Abstract:

Microneedles are small-scale devices that may be used for access to interstitial fluid and/or capillary blood for transdermal monitoring of chemicals [1]. In this presentation, the integration of several types of electrochemical sensors with hollow microneedles will be considered. For example, carbon fiber electrodes have been integrated with digital micromirror device-produced microneedles; ascorbic acid and hydrogen peroxide were detected with these devices [2]. Carbon paste electrodes have also been integrated with digital micromirror device-produced microneedles; electrodes made from rhodium-dispersed carbon paste were used for hydrogen peroxide sensing [3]. In addition, lactate oxidase-modified rhodium-dispersed carbon paste electrodes were demonstrated for lactate sensing, including in the presence of interferents such as ascorbic acid, uric acid, and acetaminophen. A multiplexed microneedle array containing digital micromirror device-produced microneedles was subsequently used for amperometric detection of glucose, lactate, and pH; detection of these analytes in complex media was shown [4]. More recently, digital micromirror device-produced hollow microneedles were modified with a working sensor, which was prepared with graphene ink and 4 (3-Butyl-1-imidazolio)-1-butanesulfonate) ionic liquid. Direct oxidation of fentanyl via square-wave voltammetry was shown; a detection limit of 27.8 μM was demonstrated using this approach [5]. Two photon polymerization has also been used to create hollow microneedles for biosensing; a porous carbon electrode created using interference lithography was used for potassium ion sensing in the presence of interfering sodium ions [6]. In another study, nitrogen-incorporated ultrananocrystalline diamond coatings were deposited on Ti –6Al–4V alloy microneedles using microwave plasma enhanced chemical vapor deposition; dopamine and uric acid were electrochemically detected in an in vitro study [7]. These studies indicate that microneedles may have utility for minimally invasive detection of analytes in a real time manner. Benefits and disadvantages of the microneedle-based sensing approach as well as efforts needed for clinical translation of microneedle-based sensing technology will be considered.

Abstract:

Aims: To derive an expression for change in entropy of spinning black holes on the basis of the model for the energy of spinning black holes ( Mahto et al. 2011a) & the model for entropy change ( Mahto et al. 2011b) and then calculate their values for different test spinning black holes. Study Design: Data for the mass of black holes have collected from the research paper entitled :Super massive Black Holes in Galactic Nuclei: Past Present & Future Research(2005), Space Science Reviews by L. Ferrarese & H. Ford and Black holes in Astrophysics(2005), New Journal Physics by R. Narayan. The data for black hole constant for spinning black holes () is taken from the paper entitled: Study of Schwarzschild radius with reference to the spinning black holes. Bulletin of Pure and Applied Sciences (2011a). Place and Duration of Study: Department of Physics, Marwari College Bhagalpur and University Department of Physics, T.M.B.U. Bhagalpur, between December 2013 and March 2014. Methodology: A theoretical based work using Laptop to calculate the calculation for change in entropy of different test spinning black holes at Marwari College Bhagalpur and the residential research chamber of the first author. Results: The calculation shows that the change in entropy of spinning black holes of the rest masses for stellar – mass black holes (M ~ 5 ­ 20 Mʘ) in X-ray binaries is to J/K and for the super massive black holes (M ~ 106 – 109.5 Mʘ) in active galactic nuclei is to J/K. The nature of the graph for XRBs is the same to the Hawking entropy with the event horizon and straight line for AGN which confirms the validity of equations and . Conclusion: The change in energy and entropy of black holes are mainly dependent on the mass and independent of their event horizons.

Abstract:

Healthcare education and practice has significantly been impacted by COVID-19. This includes the challenge on pedagogical approaches that highlight the potential of technology to facilitate innovative new approaches in response to social distancing, lockdowns, remote learning and improving the patient experience and positive outcomes. Many of these innovative approaches are not fundamentally new but are now seeing relevance beyond early adopters to mainstream implementation. This presentation draws upon collaborations with educational researchers and technologists that have explored the integration of technology into healthcare education and practice. COVID-19 Adversity to Opportunity Many healthcare programmes required reenvisaging teaching and learning approaches in response to COVID-19 restrictions. This had a particular impact on the development of interpersonal and practical knowledge and skills essential for healthcare graduates. The limited access to on-campus learning provided an opportunity for both institutional and individual evaluation of pedagogical practices. The affordances of traditional, didactic, and “hands-on” skills were compared with those that could be facilitated using online asynchronous/ synchronous strategies. A particular concern was the development of the interpersonal and practical skills required in safe and effective healthcare practice. Alongside easing of restrictions, these skills were adapted using online demonstrations within the limits of socially distanced “bubbles”, telehealth and limited clinical placements. Reconsideration of summative assessments was also required- with the introduction online synchronous and asynchronous verbal assessments, and asynchronous submissions of practical skills online (Cochrane et al., 2021; Narayan et al., 2021). In the prospect of COVID-19 restrictions continuing to lift, it is envisioned that most of the reenvisaged pedagogical approaches to healthcare education will persist, without compromising student critical thinking or practical skills. Interprofessional Collaboration This presentation will highlight the importance of interprofessional collaboration in healthcare curriculum design using a Design-Based-Research methodology (Chen et al., 2020; Kartoğlu et al., 2020) to facilitate authentic learning and develop self-determined learning capabilities for healthcare professionals. DBR- Design Principles in response to COVID Transferable design principles will be introduced for enhancing healthcare education that will improve practice in a COVID19 world, particularly drawing from eight healthcare projects including: STUDIO602 – enhancing clinical practice with mobile technologies (Cochrane & Sinfield, 2021), developing a virtual reality handover experience for healthcare students (Cochrane et al., 2018), using immersive reality to develop critical thinking in clinical health education (Stretton et al., 2018), enhancing first responder clinical simulation education using immersive reality and biometrics (Cochrane et al., 2020), designing authentic learning for graduate entry nursing students (Macdiarmid et al., 2021), designing public and environmental health education (Kersey et al., 2018), Biomedical engineering (Lam et al., 2021), and physiology education (Fabris et al., 2019).

Abstract:

ABSTRACT Reconstruction of the post-burn contracture is a complex task in plastic surgery. A burn patient treated traditionally only by dressings develops scar with contracture involving the burned region. The lip is a part of the face that is frequently affected by burn injury. Post-burn scar sequelae in this area often result in cosmetic disfigurement and psychological upset in patients. Microstomia poses difficulty in airway intubation during anesthesia and contracture of the neck if present confounds difficulty. Reconstruction of post-burn oral commissure aims to restore both symmetry of the lips (esthetic) and full oral competence (functional). Frequently treated in our department, we present a case series of post-burn contracture of neck with microstomia whose neck extension and mouth opening both were restricted giving less option but more challenge for both anesthesiologists and plastic surgeons.

Abstract:

ABSTRACT Purpose Several antiplaque agents are being available in the market in spite of vast development of modern medical science, satisfactory treatment of ‘oral diseases’ by newer drugs is not fully achieved, rather the chemical compounds has exposed the patients to it is different ill effects, therefore, there is interest to find out effective remedy of any disease by harmless herbal drugs thus the aim of this study was to compare plaque formation at 24 hours after the use of Triphala, Hi ora, Chlorhexidine and colgate plax mouth washes. Methods A controlled, randomized, double-blind, crossover clinical trial was designed. Thirty subjects underwent four consecutive experimental phases with four treatments: Triphala, Hi Ora, Chlorhexidine and colgate plax. On the day of study, the subjects discontinued all other oral hygiene habits and were randomly assigned for treatment with the experimental mouthwash. Each experimental phase was preceded by a 28- day washout period. Plaque formation was recorded after one undisturbed day. Results Triphala, Hi Ora and Chlorhexidine reduced de novo plaque formation to a greater extent than the colgate plax mouthwash (p < 0.05). Conclusion Triphala and Hi Ora presents an anti-plaque efficacy similar to that of chlorhexdine, and was more effective at inhibiting plaque formation than the colgate plax mouth wash.

Abstract:

BackgroundSleep disorders are prevalent in rheumatoid arthritis (RA). Sleep is closely related to disease activity, depression, stress, fatigue and pain [1]. Community prevalence of sleep disorders in India varies from 6.2% to 36.3% [2,3]. Studies assessing sleep quality in the Indian population with RA are limited.ObjectivesTo assess the prevalence of impaired sleep quality using Pittsburgh Sleep Quality Index (PSQI) and determine factors predicting impaired sleep quality in patients with RA.MethodsA cross-sectional study was conducted in patients with RA presenting to our rheumatology clinic after informed consent and Ethics Committee approval from January 2021. Sleep quality was assessed by PSQI, depression by Patient Health Questionnaire (PHQ-9) and Quality of life by Indian Health Assessment Questionnaire (IHAQ). Disease activity was assessed using Disease Activity Index (DAS28 CRP) and Clinical Disease Activity Index (CDAI). Serum samples for interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α) were collected and stored at -800C. Relationship of fatigue was examined with age, serum TNF-α, IL-1, IL-6, CDAI, DAS28 CRP and patient global assessment (PtGA) using Spearman correlation coefficient. Linear regression analysis was performed to determine the predictors of impaired sleep quality in patients with RA.ResultsOne hundred and fifty-four patients were enrolled, 133 were females (86.3%). Median pain VAS score was 6[2]. Mean DAS was 4.35 ± 1.31, mean CDAI: 19.75 ± 7.91 and median IHAQ was 9.5[8]. The prevalence of depression (PHQ-9 >10) was 5.8% (n = 9) with a median PHQ-9 of 2[3]. One patient was on tofacitinib, 20 were on methotrexate monotherapy and others were on combination of conventional DMARDs.The prevalence of impaired sleep (PSQI >5) was 8.4% (n = 13) with a median PSQI of 2[2]. PSQI had significant correlation with PHQ-9 (r = 0.471, p<0.0001), IHAQ (r = 0.288, p<0.0001), DAS28 (r = 0.197, p = 0.015) and CDAI (r = 0.235 p = 0.003). Age, pain VAS, serum TNF-α, IL-1 and IL-6 had no correlation with PSQI. Among individual components of DAS, PtGA (r = 0.296 p <0.0001) alone correlated with PSQI. PHQ-9, IHAQ and PtGA were significant predictors of impaired sleep quality (Table 1).ConclusionCompared to other studies within India, our patients had very low prevalence of impaired sleep quality. Sleep quality significantly influences disease activity likely by affecting PtGA. Risk factors for poor sleep quality are presence of depression, poor quality of life and patient global assessment of disease activity. Hence a holistic management of RA must involve addressing these risk factors.Table 1.Predictors of impaired sleep qualityPredictorsβ (95% CI)P valuePtGA0.176(0.023 - 0.412)0.004Depression (PHQ-9)0.282 (0.101 - 0.342)<0.0001IHAQ0.230 (0.025 -.129)0.004References[1] McBeth J, Dixon WG, Moore SM, Hellman B, James B, Kyle SD, et al.

Abstract:

ABSTRACT Introduction The ultimate success of fixed prosthesis is to pay meticulous attention to the detailed production of the missing tooth structure. Such an accurate replication is technically demanding. Hence, the aim of the study was to evaluate the accuracy of marginal fit of castings with varying sprue diameter and using ring and ringless techniques. Materials and methods Forty standardized wax copings were fabricated on a stainless steel die and divided into two groups. The first group was cast using the metal ring investment technique; the second group was cast using the ringless investment technique. Both the groups were further divided into two groups, each based on the diameter of the sprue (groups I and III: 4.5 mm and groups II and IV: 2.5 mm). The vertical marginal gap was measured at three sites per specimen, using a digital optical microscope at ×100 magnification. The results were analyzed using two-way analysis of variance and independent t-test to determine statistical significance. Results The vertical marginal gaps of castings fabricated using the ringless technique (0.145 ± 0.072 mm) were significantly less (p < 0.001) than those castings fabricated using the conventional metal ring technique (0.264 ± 0.100 mm); however, the vertical marginal gaps of the 2.5 mm sprue diameter (0.199 ± 0.092 mm) and 4.5 mm sprue diameter (0.211 ± 0.118 mm) castings were not statistically significant (p > 0.05). There was also statistically significant interaction (p < 0.001) between group IIA (0.120 ± 0.038 mm) and group IA (0.302 ± 0.098 mm), which was analyzed using the independent t-test. Conclusion It can be concluded that the ringless casting technique in comparison to metal ring technique produces metal castings of better marginal adaptation. Furthermore, the sprue diameter had significant difference wherein the 4.5 mm diameter produced the least vertical discrepancies in the ringless casting technique and 2.5 mm produced lesser vertical discrepancies in the metal ring. Clinical significance One of the key factors that decides the success of a metal-ceramic restoration is the marginal fit. The accurate fit of the restoration greatly minimizes the plaque accumulation, offers good mechanical properties, and reduces micro-leakage and development of secondary caries. The techniques of casting procedure and sprue diameter can have an influence on the outcome. Hence, the current research was undertaken to study the influence of these factors on marginal fit.

Abstract:

Morphological instability of the lithium-electrolyte interface is a critical problem limiting the development of lithium-metal negative electrodes for batteries. At high current densities approaching the diffusion-limited current density, dendrites form due to depletion of Li+ ions near the electrode surface (1). At lower current densities, unstable deposition produces whiskers (2). Whiskers are separated by typically several micrometers, and in contrast to dendrites grow by addition of Li atoms to their base or "root" (3). Experimental evidence indicates that whisker growth is fed by large-scale interface or grain boundary diffusion, and that whiskers relieve compressive stress in the metal generated by electrodeposition (4-7). The present study proposes that Li electrodeposition is destabilized by interface diffusion driven by compressive stress due to incorporation of Li atoms at grain boundaries. The competition between stress and stabilizing surface energy effects generates a surface pattern which determines (in part) whisker sites. A morphological instability model is formulated based on the Asaro-Tiller-Grinfel'd (ATG) surface instability on elastically stress solids (8). The model applies to deposits less than 1 micron thick for which elastic deformation is expected to dominate (9,10). The Li electrode is depicted by a three-layer elastic model consisting of a stress-free substrate (current collector) layer, a Li layer with uniform diffusion-induced in-plane stress, and top layer. The top layer can simulate submicron thickness solid-electrolyte interface (SEI) layers, or macroscopically thick polymer separators and solid electrolytes. The Li-top layer interface deforms by diffusion. Out-of-plane normal stress is included to simulate the effect of applied stress on the instability (11,12). For model calculations, the interface stress was estimated from neutron-depth-profiling measurements of Li diffusion into Cu current collectors (13). The measured Li incorporation was found to be consistent with a whisker spacing of several microns, in agreement with experimental results (3,6,14). Calculations showed that the instability is inhibited significantly by the use of substrates with elastic modulus much greater than that of Li. This substrate stiffness effect is consistent with experimental observations of Sn whiskers (15). The effect of a stress-free SEI layer on the instability was found to be negligible, due to its small thickness. Whisker growth was suppressed by macroscopically thick top layers with elastic modulus at least 10 times that of Li. No significant whisker inhibition was found at applied stress levels of ~ 1 MPa, which are found experimentally to stabilize deposition in Li films significantly exceeding 1 micron thickness (11,12). This effect may be due to an instability associated with viscoplastic rather than elastic deformation (16). REFERENCES P. Bai et al., Energy Environ. Sci., 9, 3221(2016). L Frenck et al., Front.

Abstract:

Abstract B-cell acute lymphoblastic leukemia (B-ALL) is an aggressive hematological malignancy of B lineage progenitors. It remains a leading cause of death in childhood, while outcomes in adults are dismal. There is therefore a need to better understand drivers of high-risk B-ALL and to develop novel therapeutic approaches targeting these challenging patient cohorts. Loss-of-function mutations affecting CREBBP are recurrent second-hit mutations across multiple genetic subtypes of B-ALL and are associated with adverse features, including high-risk genetic subtypes and persistent measurable residual disease. In addition, they have been mechanistically associated with chemoresistance and are more frequently found in relapse. We sought to identify novel treatment options for CREBBP-mutated high-risk B-ALL. CREBBP-mutated isogenic human B-ALL cell lines were genome-engineered to provide a platform for synthetic lethal drug screening. We subjected these cell lines to a targeted drug screen focused on clinically-actionable drugs in classes that have either been implicated or hypothesized to show differential sensitivity patterns in published models of B cell lymphoma and other CREBBP-mutated malignancies. Unexpectedly, CREBBP-mutated cells were not differentially sensitive to traditional cytotoxic chemotherapy, and paradoxically showed a degree of sensitization to the glucocorticoid Dexamethasone, used in current ALL induction regimens. As anticipated, and validating our screen design, inhibitors of the CREBBP paralogue EP300 (the CREBBP/EP300-specific bromodomain inhibitor Inobrodib and the CREBBP/EP300 acetylase inhibitor A485) exhibited synthetic lethality, consistent with previous reports in B-cell lymphoma. The most potent hit was the BCL2 inhibitor Venetoclax, which we show acts through a non-canonical, but BCL2-dependent mechanism resulting in ferroptotic programmed cell death. CREBBP-mutated cell lines were transcriptionally and functionally characterized, revealing underlying differences in cell-cycle, metabolism and response to oxidative stress. Acquisition of resistance to Venetoclax further dysregulated these pathways and resulted in a transcriptionally-convergent state. Lastly, we demonstrate that small-molecule inhibition of CREBBP sensitizes B-ALL cells, regardless of genotype, to Venetoclax-induced ferroptosis in vitro and in vivo, providing a potential novel drug combination for broader clinical translation in B-ALL. In summary, we have identified a number of actionable compounds that specifically target CREBBP-mutated high-risk B-ALL, demonstrate a novel mechanism-of-action for the BCL2 inhibitor Venetoclax in B-ALL and propose CREBBP-inhibitors and Venetoclax as a novel treatment combination for B-ALL across genotypes.

Abstract:

This technical note summarizes a technical comparison of common testing procedures, as well as reviewed of the UN Test N` 5, for the assessment of the self-heating properties of cargoes and materials that has shown a clear trend on maritime fire and explosions events, as well as considering of external factors that can combine self-heating and emit flammable gases to conclude in an unlikely event affecting the security of crews and ships. A high understanding of the external factors effect on the cargo materials certainly will help the application of spontaneous reactions management actions (SRMA) on board of ships during the cargo sea passage. The intended comparison is based on laboratory, industry and field observations and data, whereas the among the external factors considered are, moisture content, stockpile procedure and aging, air velocities and moderate pressures internal and externally to the cargo material. The comparison results have shown that the self-heating and the flammable gas emissions has a common pattern when reacting with any oxygen available source, regardless the reactive material chemical composition. Keywords: reactive materials, self-heating, self-ignition, direct reduced iron fines, materials handling, UN test N` 5, maritime safety, spontaneous reactions, risk management. IMSBC Code , IMO.

Abstract:

We consider one of the fundamental problems of classical invariant theory - the research of Poincare series for an algebra of invariants of Lie group $SL_2$. The first two terms of the Laurent series expansion of Poincare series at the point $z = 1$ give us important information about the structure of the algebra $\mathcal{I}_{d}.$ It was derived by Hilbert for the algebra ${\mathcal{I}_{d}=\mathbb{C}[V_d]^{\,SL_2}}$ of invariants for binary $d-$form (by $V_d$ denote the vector space over $\mathbb{C}$ consisting of all binary forms hom*ogeneous of degree $d$). Springer got this result, using explicit formula for the Poincare series of this algebra. We consider this problem for the algebra of joint invariants $\mathcal{I}_{2n}=\mathbb{C}[\underbrace{V_2 \oplus V_2 \oplus \cdots \oplus V_2}_{\text{n times}}]^{SL_2}$ and the algebra of joint covariants $\mathcal{C}_{2n}=\mathbb{C}[\underbrace{V_2 {\oplus} V_2 {\oplus} \cdots {\oplus} V_2}_{\text{n times}}{\oplus}\mathbb{C}^2 ]^{SL_2}$ of $n$ quadratic forms. We express the Poincare series $\mathcal{P}(\mathcal{C}_{2n},z)=\sum_{j=0}^{\infty }\dim(\mathcal{C}_{2n})_{j}\, z^j$ and $\mathcal{P}(\mathcal{I}_{2n},z)=\sum_{j=0}^{\infty }\dim(\mathcal{I}_{2n})_{j}\, z^j$ of these algebras in terms of Narayana polynomials. Also, for these algebras we calculate the degrees and asymptotic behavious of the degrees, using their Poincare series.

Abstract:

Abstract Introduction: Extensive research studies on breast cancer disparities have had limited impact on reducing breast cancer disparities. Quality improvement initiatives use data-driven, rigorous approaches to plan, execute, and study the delivery of healthcare services. There have been limited studies using quality improvement methods to address health disparities. The purpose of our study was to describe the design of a quality improvement initiative to address breast cancer disparities using the A3 problem solving method. Methods: A3 problem solving method was used to reduce breast cancer screening disparities. The A3 method is a quality improvement tool used to identify problems, organize and synthesize data, and propose solutions to achieve goals (summarized on one side of a sheet of paper). A3 methods are outlined by the FOCUS-PDCA acronym: F - Find process to improve, O - Organize team of stakeholders, C - Clarify current state, U - Understand sources of variation that contribute to the problem, S - Select change ideas, P - Plan and do the improvement, C - Check the results, A - Act. Quantitative data was derived from the electronic medical record. Qualitative data was derived from divergent thinking exercises asking participants from diverse standing urban stakeholder groups about barriers to cancer screening. Results: Design of the A3 problem solving process was conducted between November 2022 until May 2023 yielding the following FOCUS-PDCA design and initial results. F - Increase the percentage of patients who have undergone mammography screening within the last two years. O - Team includes representative leaders from primary care, community health, ambulatory operations, diversity, equity, and inclusion, radiology, breast center, population health, information services, and federally qualified health centers. C and U - Quantitative data collection revealed that 74% of 37,509 eligible patients (women between 50-74 years old) received a mammogram within the last two years (75% White, 58% Black, 67% Asian, 60% American Indian, 64% Hispanic). Divergent thinking exercises revealed the following root causes for mammography screening disparities: patients don’t know they are due, transportation issues, barriers to scheduling, access to mammography facilities, financial concerns, and fears about returning to clinics during COVID-19. S - Process improvements included multilingual and modality reminders, marketing campaigns, transportation vouchers, co-location of screening centers with federally qualified health centers, expanded access to mammography screening facilities, educational activities for primary care physicians, participation in community events, equity-focused review of screening guidelines. PDCA - Based on selected improvements, changes in breast cancer screening percentages will be displayed using run charts until December 2024, stratified by race and ethnicity. Conclusion: A3 problem solving tools represent structured, scientifically rigorous approaches that cancer centers can use to reduce screening disparities. Citation Format: Nia Foster, Arissa J.

Abstract:

Lithium microstructure formation is the limiting factor preventing the application of lithium metal anodes and, to some degree, fast-charging of graphite anodes, because of enhanced cell degradation and risks of short-circuits. To improve mechanistic understanding and develop prevention strategies, a complementary analytical tool set is necessary. Contributing to non-invasive in operando techniques, we present pulse electron paramagnetic resonance (pEPR) with a practical sampling rate of 100 microseconds, providing a global view on lithium microstructure formation and evolution.[1] pEPR experiments offer an estimate of the dimension and size distribution of the morphology that is in line with post-test SEM characterization. For lithium metal anodes, the sampling rate is sufficient to observe dynamic morphology changes that evolve for several seconds after fresh lithium deposition, attributed to surface smoothening, comparable to recently observed heating-induced healing of dendrites.[2] For graphite anodes, lithium plating can be followed at C-rates up to 18C. Quantitative measurements reveal an exponential increase of deposited lithium mass upon galvanostatic charge. The plating onset is pinpointed to the characteristic voltage drop well below 0 V vs. Li/Li+.[3] After stopping the charge at intermediate states of charge, the partial intercalation of lithium can be monitored at OCV, identifying two kinetic domains and the amount of remaining dead lithium.

Abstract:

Rechargeable sodium (Na) batteries that utilizing solid-state ion conductors have attracted intense attentions for large-scale energy storage systems due to the abundant resources of Na compounds and electrochemical voltage (2.70 V vs. 3.05V for Li). So far, the most popular inorganic Na-ion SEs include oxides, halides, and chalcogenides such as Na3PhCh4 (Ph=P, Sb; Ch=S, Se) etc. In specific, Na3SbCh4 (Ch=S, Se) chalcogenide conductors exhibit impressive ionic conductivity at room temperature due to vacancy-assisted three-dimensional (3D) ion transport channels. In this talk, we will introduce our works on the studies on in-situ synthesis of Na chalcogenide solid electrolytes (SEs) and several strategies for interface stabilization of such SEs towards Na anode. The in-situ synthesis studies of Na3SbCh4 (Ch=S, Se) reveal the structural evolutions during the solid-state reaction process.1 Besides, efficient interface stabilization strategies have been demonstrated to enable solid-state Na metal batteries that using Na as the anode, and metal sulfide (TiS2 or FeS2) as the cathode.2, 3 For instance, phase transition interlayer (PEG-PPG-PEG) has been successfully proved to prevent the side reactions between the Na3SbS4 SE and Na metal and contribute to the uniform Na deposition at interface to prevent dendrite formation and growth. The goal of our work is to develop novel chalcogenide Na conductors and promote their applications in solid-state Na batteries.

Abstract:

ABSTRACT Aim To compare laryngeal preservation rates, survival rates, and voice outcomes after treatment of early glottic cancer between transoral laser microsurgery (TLM) and radiotherapy (RT). Materials and methods A review of oncologic results was performed on a consecutive series of individuals with early-stage glottic carcinoma (T1 and T2) who were treated between 2011 and 2014 at Kidwai Memorial Institute of Oncology and had received either RT or TLM. Data were collected with a view to assess overall survival, disease-specific survival, laryngectomyfree survival, and laryngeal preservation rates. The Voice Handicap Index-30 (VHI-30) was used as the measure of voice quality after treatment. Results Two-year overall survival for TLM group was 93.8% and for RT group was 90.5%, p = 0.643. Disease-free survival (TLM = 90.6% vs RT = 76.2%) was not found to be significant (p-value = 0.104). Laryngeal preservation rate was 79.5% in TLM and 71.4% in RT group (p-value = 0.003). Laryngectomy- free survival was better in TLM (TLM = 96.9% vs RT = 76.2%, p = 0.003). Substage analysis showed equivalent voice for TLM (VHI = 6–12) and RT (VHI = 6–14) in T1a patients (p = 0.94), whereas voice outcome was better for RT in T1b (VHI = 10–16 for TLM vs VHI = 11–18 for RT, p = 0.044) and T2 (VHI = 21–29 for TLM vs VHI = 16–23 for RT, p = 0.002) stages. Conclusion Transoral laser microsurgery can be considered the treatment of choice for early glottic cancer in view of better laryngeal preservation rate and laryngectomy-free survival with added advantage of low treatment cost and shorter hospital stay compared with RT. Clinical significance Laryngeal cancers represent the most common malignancy of head and neck, with estimated worldwide incidence of 120,000 cases annually. Optimal treatment modality has generated significant controversy in literature. External beam RT, open partial laryngectomy, and TLM are various treatment options available. This study depicts TLM as a preferred modality for early glottic cancer.

Abstract:

Slurry electrodes have been proposed as a means to enhance the scalability of hybrid redox flow battery (RFB) chemistries for better usability in utility scale energy storage applications1–3. In conventional hybrid RFB’s, scalability is limited due the spatial constraints of the flow cell and the metal deposited by the negative half-reaction on charge1. By using a slurry electrode, the solid metal can be deposited onto electrically conductive particles dispersed in the electrolyte instead of on the stationary electrode within the flow cell. In this way, hybrid RFB chemistries can achieve the same scalability as more commonly studied true RFB chemistries, such as all-vanadium. Due to the high abundance, low cost, and low toxicity of iron electrolytes, the all-iron RFB chemistry is of particular interest for use with a slurry electrode2,4. The usefulness of the slurry electrode depends on the current distribution of the plating reaction. To successfully decouple the storage and power capacities of the RFB and thus enhance its scalability5, the faradaic current of the plating reaction must occur predominantly on the mobile slurry particles, as opposed to on the stationary current collector1. This current distribution is dependent on a variety of factors, such as the applied overpotential, the electrical conductivity of the slurry, the ionic conductivity of the electrolyte, the kinetics of the reaction, and the rate of ionic mass transport to reaction sites. Ionic mass transport in electrolytes containing slurry electrodes may differ from ionic transport in neat electrolyte in interesting and important ways. Due to the volume fraction of the electrolyte occupied by solid particles, the effective concentration of the ionic species may be lower than in neat electrolyte. Further, the solid particle volume fraction hinders ionic diffusion by introducing diffusion path tortuosity. This effect is more severe in higher slurry particle loadings. In this work, the effect of varying dispersed solid particle loading on ionic diffusivity is investigated via voltammetry using a rotating disk electrode. The diffusivities of ionic iron species are measured as a function of the volume fraction of solids dispersed in the electrolyte. Comparisons with the Bruggeman correlation6,7 are made and amendments to the Levich equation are considered. (1) Petek, T. J.; Hoyt, N. C.; Savinell, R. F.; Wainright, J. S.

Abstract:

ABSTRACT Aim To evaluate and compare various nuclear morphometric parameters in different histopathological grades of oral squamous cell carcinoma (OSCC) by using computerized image analysis and also to correlate it with regional lymph node metastasis. Materials and methods This retrospective study was conducted on paraffin blocks of 40 tissue specimens of OSCC cases treated with neck dissection, which were retrieved from the archives of the Department of Oral Pathology and Microbiology, Mahatma Gandhi Mission’s Dental College and Hospital, Navi Mumbai, India. All cases were histopathologically graded as well, moderately, and poorly differentiated OSCC. Further, they were also categorized based on pathological lymph node status as with or without lymph node metastasis. Sections from tumor proper were subjected to Feulgen nuclear staining technique. Images of 10 microscopic fields at the deepest invading part of tumor were captured randomly and 100 nuclei of tumor cells with clear, complete, nonoverlapping outlines were selected in each case. Nuclear morphometric parameters, such as large diameter, small diameter, nuclear area, and nuclear perimeter were measured for each of the 100 cells. Results An increase in mean nuclear area coefficient of variation (NACV) was observed in OSCC cases with lymph node metastasis pN(+) than in those without lymph node metastasis pN(–), (p = 0.67). A significant increase in nuclear area and perimeter was observed in pN(+) cases (p < 0.01). A significant decrease in circular rate and increase in largest to smallest nuclear diameter (L/S) ratio (p < 0.01) was observed in pN(+) cases. On comparing the nuclear morphometric parameters with different histopathological grades of OSCC, we found an increase in mean NACV values from well-differentiated OSCC to moderately differentiated and poorly differentiated OSCC (p = 0.612). An increase in mean nuclear area and perimeter was noted as grades of OSCC advanced (p > 0.01). The mean circular rate was found to be lowest in poorly differentiated OSCC (p = 0.362). A significant increase in mean L/S ratio was observed within different histopathological grades of OSCC (p = 0.044), which when further confirmed using least significant difference (LSD) post hoc test, indicated a difference only between well-differentiated and poorly differentiated cases of OSCC (p = 0.132). Conclusion Our observations reveal that tumor cells with greater nuclear dimension and more elliptical shape tend to show increased incidence of nodal metastasis. Also, a positive inclination was observed in nuclear size and shape with increasing histopathological grades of OSCC. However, our data warrant a large-scale study to establish nuclear morphometry as a quantitative objective parameter and also for the rational application of the same.

Abstract:

ABSTRACT Islamic banking is undoubtedly faced with several potential financing risks, with the three largest financing contracts (Mudharaba, Musharaka, and Murabaha) that reduce the financial performance of Islamic banks. The potential risk is strengthened if the stability of national economic growth is contracted. Therefore, this research aims to investigate the impact of Mudharaba, Musharaka, and Murabaha financing on Financing Risk moderated by the business cycle and the relationship between Financing Risk and the Financial Performance of Islamic Commercial Banks. The sample of this study was 12 Islamic Commercial Banks in Indonesia during the period 2017-2021. The Data were then analyzed using the technique of Moderated Regression Analysis (MRA). Researchers found that Musharaka financing has a significant positive effect on Financing Risk, Mudharaba and Murabaha Financing has an insignificant effect on Financing Risk, and Financing Risk has a significant negative effect on Financial Performance. The Business Cycle does not moderate the Financing of Mudharaba, Musharakah, and Murabaha on Financing Risk. The results can encourage the Islamic Commercial Bank to evaluate the distribution strategy of Musharaka financing, optimize the distribution of Mudharaba and Murabaha financing, and prepare financing strategies that do not depend on macroeconomic conditions. Keywords: Financing Risk, Financing, Business Cycle, Financial Performance. ABSTRAK Perbankan syariah dengan tiga akad pembiayaan terbesar (Mudharaba, Musharaka, dan Murabaha) dihadapkan pada sejumlah potensi risiko pembiayaan yang menurunkan kinerja keuangan Bank Syariah. Potensi risiko tersebut menguat jika stabilitas pertumbuhan ekonomi nasional juga terganggu atau mengalami kontraksi. Oleh karena itu, penelitian ini hendak mengkaji pengaruh Pembiayaan Mudharaba, Musharaka, dan Murabaha terhadap Risiko Pembayaran dengan dimoderasi oleh Siklus Bisnis, dan sekaligus menguji hubungan antara Risiko Pembayaran dan Kinerja Keuangan Bank Syariah. Sampel penelitian ini adalah 12 Islamic Commercial Bank di Indonesia selama periode 2017-2021. Data tersebut kemudian dianalisis dengan menggunakan teknik Moderated Regression Analysis (MRA). Peneliti menemukan bahwa Pembiayaan Musharaka berpengaruh positif signifikan terhadap Risiko Pembiayaan, Pembiayaan Mudharaba dan Murabaha tidak berpengaruh signifikan terhadap Risiko Pembiayaan, dan Risiko Pembiayaan berpengaruh negatif signifikan terhadap Kinerja Keuangan. Adapun Siklus Bisnis tidak dapat memoderasi Pembiayaan Mudharaba, Musharaka, dan Murabaha terhadap Risiko Pembiayaan. Hasil penelitian ini dapat menjadi evaluasi bagi Islamic Commercial Bank agar dapat mengevaluasi strategi penyaluran pembiayaan Musharaka, mengoptimalkan penyaluran pembiayaan Mudharaba dan Murabaha, dan mempersiapkan strategi pembiayaan yang tidak bergantung pada kondisi makro ekonomi.

Abstract:

ABSTRACT Introduction Mishri is one of the form of smokeless tobacco, which is a roasted, powdered preparation made by baking tobacco on a hot metal plate until it is uniformly black, after which it is powdered. It is noted that mishri use is more commonly used by the women of low socioeconomic status, hence the need was felt to conduct this study among women mishri users of slums. Also, the consequences of mishri use are little known, hence an effort is made to find out its ill-effect on oral health. Objective To assess knowledge, attitude, and practice (KAP) among women using mishri regarding its effects on their oral and general health. Materials and methods A 6-month KAP study was conducted among 100 women who were using mishri. Snowball sampling was used. Oral examination of the participants was also done for oral potentially malignant disorders, such as leukoplakia, erythroplakia, oral submucous fibrosis, and hyperkeratinized pouch. Results About 61% of the population used mishri for cleaning the teeth and others used it as quid; 0.85% of the total participants knew that the use of mishri may lead to precancerous lesions/conditions. Only 17% knew that mishri use can cause gum disease; 84% of the population was willing to quit the habit of using mishri. Conclusion It is concluded that all the participants had poor knowledge. Attitude toward quitting mishri use was found to be good. About 4% of the participants reported about quitting the habit. Clinical significance There is need to create awareness regarding harmful effects of mishri usage in this particular area to improve oral health status.

Abstract:

ABSTRACT Objectives To assess clinical skills of interns in selected procedures using direct observation of procedural skills (DOPS) To assess the change in procedural skills among students who received a structured feedback on DOPS. Materials and methods The study was interventional and conducted between December 2015 and February 2016 at the Department of Obstetrics and Gynaecology of Sree Narayana Institute of Medical Sciences, Ernakulam, Kerala, India. In the study, investigator observed the trainee performing a practical procedure within the workplace and recorded a rating for each competency on the assessment form. Feedback was given expanding on the reasons for any ratings of development required and makes practical suggestions for any remedial steps. The intern is reassessed for the same procedure at a later stage and the impact on skills is scored. Then the structured feedback is provided, and later on again the score on skills obtained by DOPS are compared between pre- and post-values by Wilcoxon-signed rank test. Results The average of pre- and post-feedback values were compared by Wilcoxon signed rank test. The p-value calculated was <0.001, which is significant. None of the interns were competent to perform the procedure before feedback; 80% of them needed more practice and 20% needed supervision. After feedback, 53.3% achieved competency and 46.7% achieved competency needing supervision; 93.3% of interns regarded feedback as superior quality, while 6.7% regarded as satisfactory. Conclusion Direct observation of procedural skills can be used to assess clinical skills of interns in selected procedures and it brings changes in procedural skills among students who received a structured feedback on DOPS.

Abstract:

The development of energy systems in which solar radiation acts as an energy input is the most attractive alternative for meeting global demand in a sustainable manner in the near future. Since photovoltaic technologies are limited by the daily and seasonal intermittencies inherent in solar radiation, they often work in tandem with batteries, which can store electrical energy as electrochemical energy to be supplied on demand. However, a monolithic device that integrates electrical energy production and storage by sharing a common electrode is not yet available, a challenge since 1976 when this concept was first reported1. But, it has been in the last decade when the interest in this type of systems has increased due to advances in portable electronics and the potential in applications such as microbots or for the IoT (internet of things). In these applications, the device shape and weight factor, portability and decentralization of production and energy storage are more important properties than the overall efficiency of the process. The studies of photorechargeable batteries in the decade of 2010 were mainly based on dye-sensitized solar cells2, and extended to Li-ion batteries3. More recently, photorechargeable lithium batteries have been reported by using a semiconductor electrode with the dual functionality of light harvesting and electrochemical energy storage4, 5. However, a single material for both capacitive and light harvesting functions affects the system operation and hinders the interpretation of the physical processes because of the changes in the electrical properties of the semiconductor induced by the intercalation of ions. In a previous study, a photocapacitive system was developed based on BiVO4 light harvester and PbOx nanoparticles performing the capacitive platform by redox pesudocapacitance6. Based on this idea, a new photoelectrode based on Cu2O-TiO2 heterostructured film is studied as photoelectrode in an adapted Li coin cell (inset figure 1)7. The optical and electrochemical characterization of the electrodeposited Cu2O and nanoparticulated TiO2 films were analyzed separately by UV-vis and UPS spectroscopy and cyclic voltammetry (CV). The analysis of these results depicts an energetic scheme of the heterostructure system that explains the cyclic voltammetry registered at different light powers (figure 1). Then, a Cu2O-TiO2/Li photobattery is fabricated and its performance studied. The fabricated photorechargeable lithium battery can accumulate 88% of the theoretical energy density of the TiO2 electrode (~150 mAh g-1 at 0.1 C discharge rate) using only white LED illumination. The overall efficiency of the output electric energy respect to the light energy emitted by the LED is 0.29%. Beyond the photorechargeable lithium battery, this study analyzes the mechanism of operation in order to provide enlightening design rules to guide the development of a monolithic photorechargeable battery technology.

Abstract:

ABSTRACT Background Treatment with dental implants has become increasingly important in the range of prosthodontic treatment. Significant improvements in oral rehabilitation particularly in edentulous individuals have been seen. In Adhiparasakthi Dental College, Melmaruvathur, a survey was made to evaluate awareness among patients for dental implants, their level of knowledge, and attitude toward replacement of missing teeth by dental implants. Materials and methods A survey of 480 people was conducted through a printed questionnaire and completed by willing respondents. The questionnaires were prepared in English and Tamil language to enable better understanding and completion. Results Of the 510 people surveyed, 480 responses were retrieved, of which 331 were aware of dental implant treatment in Melmaruvathur, Tamil Nadu. Among them, 304 respondents were aware that implants could be used for replacement of missing teeth. Most of the respondents stated that dental implants were placed in the jawbone, followed by gums. Only 41% respondents assumed that implants last for a lifetime and only 35% of respondents believe that poor oral hygiene was the most common cause of implant failure. Conclusion More dental education programs are needed to improve understanding of the importance of restoration of missing teeth. General implant awareness levels are satisfactory. However, increased awareness of patients for restoration of missing tooth with dental implants is necessary. Dental education programs with special emphasis on advantages, treatment, maintenance, and postoperative care of dental implant therapy are needed. More than two-thirds of the surveyed population is interested in knowing about and being treated with dental implants. How to cite this article Narayanan V, Karuppiah P, Rajasekar A, Mayavan LD.

Abstract:

Amyloid-β (Aβ) has long been implicated as a causative protein in Alzheimer's disease. Cellular Aβ accumulation is toxic and causes mitochondrial dysfunction, which precedes clinical symptoms of Alzheimer's disease pathology. In the present study, we explored the possible use of epoxyeicosatrienoic acids (EETs), epoxide metabolites of arachidonic acid, as therapeutic target against Aβ-induced mitochondrial impairment using cultured neonatal hippocampal astrocytes. Inhibition of endogenous EET production by a selective epoxygenase inhibitor, MS-PPOH, caused a greater reduction in mitochondrial membrane potential in the presence of Aβ (1, 10 μM) exposure versus absence of Aβ. MS-PPOH preincubation also aggravated Aβ-induced mitochondrial fragmentation. Preincubation of the cells with either 14,15- or 11,12-EET prevented this mitochondrial depolarization and fragmentation. EET pretreatment also further improved the reduction observed in mitochondrial oxygen consumption in the presence of Aβ. Preincubation of the cells with EETs significantly improved cellular respiration under basal condition and in the presence of the protonophore, carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone (FCCP). The uncoupling of ATP synthase from the electron transfer chain that occurred in Aβ-treated cells was also prevented by preincubation with EETs. Lastly, cellular reactive oxygen species production, a hallmark of Aβ toxicity, also showed significant reduction in the presence of EETs. We have previously shown that Aβ reduces EET synthesis in rat brain hom*ogenates and cultured hippocampal astrocytes and neurons (Sarkar P, Narayanan J, Harder DR. Differential effect of amyloid beta on the cytochrome P450 epoxygenase activity in rat brain. Neuroscience 194: 241–249, 2011). We conclude that reduction of endogenous EETs may be one of the mechanisms through which Aβ inflicts toxicity and thus supplementing the cells with exogenous EETs improves mitochondrial dynamics and prevents metabolic impairment.

Abstract:

If inherently intermittent renewable energy technologies are to offer a practical alternative to conventional heat engines, it is critically important that efficient, cost-effective and sustainable energy storage solutions are developed to decouple supply and demand profiles. A promising strategy is to pair the competitive energy densities of batteries with the superior cycling lifetimes and power densities of supercapacitors,[1] employing an appropriate maximum power point tracking (MPPT) system to optimise energy exchange between these complementary devices.[2] Mixed-valence manganese(III/IV) oxides (MnOz, where z ranges between 1.5 and 2.0) have emerged as foremost candidates for the electroactive material in supercapacitor cathodes due to their low toxicity, minimal cost,[3] ready availability (manganese appears at an average concentration of ca. 1,000 ppm in the Earth’s crust[4]), wide electrochemical stability window (ca. 1.0 V in aqueous electrolytes[5]), and high maximum theoretical specific capacitance (ca. 1,370 F g-1, based on the reduction of Mn4+ ions by a single electron[6]). Charge storage in MnOz is predominantly mediated by the pseudocapacitive intercalation of cations from the surrounding electrolyte in each discharge phase, followed by the release of these guest ions during charging. Of the various crystallographic phases of MnOz, cryptomelane (α-MnOz) and birnessite (δ-MnOz) polymorphs are deemed two of the most promising candidates for storage applications because they possess characteristically wide channels for intercalation/de-intercalation:[8,9] α-MnOz consists of ca. 4.6 Å diameter one-dimensional tunnels enclosed between corner-sharing MnO6 octahedra, whereas δ-MnOz comprises two-dimensional layers of MnO6 octahedra separated by ca. 7.0 Å. Herein, a scalable, low-cost synthesis procedure is discussed that enables the production of highly pseudocapacitive birnessite and cryptomelane electrodes with tuneable material characteristics, including particle morphology, crystallographic structure, average Mn oxidation state, and the level of pre-intercalation by Na+ and K+ ions.[10] In addition to comparing the electrochemical properties of these NaxKyMnOz products in aqueous conditions, their application within an asymmetric supercapacitor is showcased: by optimising the relative masses of a NaxKyMnOz cathode and activated carbon anode in a 100 cm2 aqueous full-cell configuration, discharge capacitances in the range 10-30 F g-1 can be achieved over a voltage span of 1.8 V at current densities as high as 10 A g-1, with Coulombic efficiency exceeding 80% up to ca. 20 A g-1. With these competitive performance characteristics, the developed NaxKyMnOz materials are a promising option for high-power supercapacitor cathodes, helping to pave the way towards more efficient and sustainable energy storage.

Abstract:

Father's involvement is something that influences the child's problematic behavior. The purpose of this study is to investigate whether father involvement can influence children's problematic behavior. This study used the systematic literature review (SLR) method by referring to 10 valid articles published in the last 10 years with the publication years between 2013 - 2023. The finding of the literature shows that there is a significant impact of father involvement on the children's problematic behavior. The more the father is involved in the children's development, the lower the level of children's problematic behavior is. The image of a father as a mentor and motivator for early childhood can still be explored in depth. Because of the limitations of this study, this study suggests that future research can further discuss the impact of the father’s involvement in the children's problematic behavior in a specific cultural aspect by considering cross-cultural factors. This is intended to conclude the relationship between the father’s interactive situations with the impact of the father’s involvement in the children's problematic behavior.

Abstract:

Non-Von Neumann computing application constituted by artificial synapses based on electrochemical random-access memory (ECRAM) has aroused tremendous attention owing to its capability to perform parallel operations, thus reducing the cost of time and energy spent [1-3]. Existing ECRAM synapses comprise two-terminal memristors and three-terminal synaptic transistors (SynT). While low cost, scalability, and high density are the highlights for memristors, their nonlinear, asymmetric state modulation, high ON current withdrawal, and sneak path in crossbar array integration prevent them from becoming the ideal synaptic elements for artificial neural networks (ANN) [4]. SynT configuration, on the other hand, offers an additional electrolyte-gated control from which ion doping content can be monitored via redox reactions, thus decoupling write-read actions and improving the linearity of programming states [5-6]. Nevertheless, existing SynTs suffer from different integration issues stemming from liquid-based ionic conductors and manually exfoliated channels. Moreover, several kinds of SynTs possess highly conductive channels in the range of µS to mS, significantly scaling up the energy spent for analog states reading. Despite having numerous communications on the performance of different ECRAM, a comprehensive electrochemical view of ion intercalation into the active material, the main root of conductance modulation, is clearly missing. In this work, we present the elaboration procedure of an all-solid-state synaptic transistor composed of nanoscale electrolyte and channel layers. The devices have been elaborated on 8’’ Silicon wafers using microfabrication processes compatible with conventional semiconductor technology and CMOS back end of line (BEoL) integration. (Figure 1a) We demonstrate the excellent synaptic plasticity properties of short-term potentiation (STP) and long-term potentiation (LTP) of our SynT. We performed tests to study the correlation between linearity, asymmetry, and the number of analog states. By averaging the amount of injected ions per write operation, we estimated the energy consumed for switching among adjacent states of this device is 22.5 pJ, yielding area-normalized energy of 4 fJ/µm2. In addition, operating in the range of nS, our SynTs meet the critical criteria of low energy consumption for both write and read operations. Endurance was highlighted by cycling in ambient conditions with 100 states of potentiation and depression for over 1000 cycles with only a slight variation of Gmax/Gmin ratio of 6.2 % (Figure 1b, c). Approximately 95 % accuracy in MNIST pattern recognition test on ANN in the crossbar array configuration has been obtained by simulation with SynTs as synaptic elements reassured SynT is a promising candidate for future neuromorphic computing hardware. To shed light on the properties of intercalation phenomena of Li ions into the TiO2 layer, a further electrochemical study on a cell comprising Ti/TiO2/LiPON/Li corresponding to the SynT gate stack was performed. This understanding will help to elucidate the correlation with conductance modulation characteristics for a synaptic transistor. Multiple tests were carried out, including cyclic voltammetry (CV) with different scan rates, rate capability with Galvanostatic cycling with potential limit (GCPL), and electrochemical impedance spectroscopy (EIS) on different states of charge. A circuit model was introduced to fit the frequency response of the cell, and it explained well the behavior of charging capability at different OCV (Figure 1d). References [1] P.

Abstract:

Advanced batteries containing a Li metal anode (LMA) are needed to enable the clean economy and meet ambitious climate targets. Currently, LMA batteries are limited by dendrite propagation due to the non-uniform plating and stripping of Li, which is detrimental to cell performance. The non-crystalline solid electrolyte (SE), lithium phosphorus oxynitride (LiPON) is unique in demonstrating stable Li plating/stripping at appreciable rates, but its synthesis requires costly and slow vacuum deposition methods. We use aqueous precursor solutions which are rapidly condensed during spin coating and gently annealed to produce dense, flat, Li metal oxide films without long-range order. However, such solution-processed SEs typically exhibit ionic conductivities (σ ion ) too low for energy storage applications (~10-8 S cm-1) and far lower than vacuum-deposited LiPON (~10-6 S cm-1). We will discuss various approaches to increase the σion of these materials, including compositional engineering and controlled processing conditions. Structure-property relationships have been elucidated using modelling of the local structure and interphase formation against Li evaluated by time-dependent electrochemical impedance spectroscopy and in situ X-ray photoelectron spectroscopy. Electrochemical testing of these films deposited onto a current collector in an anode-free cell will be used to evaluate their ability to facilitate stable deposition and stripping of Li. Initial exploration of processing parameters have yielded σion values > 10-7 S cm-1 [1] and the presence of medium-range order (nanocrystalline domains) in some cases. Beyond Li, new non-crystalline SEs for other ions will be discussed. As only limited chemical compositions and processing conditions of these materials have been reported, with no corresponding structural studies, our work provides insight to enable the optimisation and discovery of scalable non-crystalline SEs for advanced batteries. 1.

Abstract:

ABSTRACT Introduction Pregnancy is a natural process that may create some changes in different parts of the body including the oral cavity. These changes will lead to oral diseases if enough and timely care of oral cavity is not taken. Women may experience increased gingivitis or pregnancy gingivitis beginning in the second or third month of pregnancy that increases in severity throughout the duration of pregnancy. To motivate the patient toward oral health and implement the needed prophylactic measures, a longitudinal study was planned to observe the effect of oral health education during pregnancy on knowledge, attitude, practice, oral health status, and treatment needs (TNs) of pregnant women belonging to different socioeconomic groups. Materials and methods A longitudinal study was conducted among 112 pregnant women belonging to different socioeconomic groups to assess the effect of oral health education on knowledge, attitude, practice, oral health status, and TNs. The demographic details, knowledge, attitude, and practice of pregnant women, and oral health status were collected through a predesigned questionnaire by a principal investigator through an interview. Oral health examination was carried out to assess oral health status using revised World Health Organization Proforma 1997, and oral health education was given through PowerPoint presentation to the participants in local language, i.e., Marathi, after collecting the baseline data. Reinforcement of oral health education and blanket referral was done at 14th week, and follow-up data were collected at 28th week of gestation. The demographic details, such as age, sex, education, occupation, income, and the questions based on knowledge, attitude, and practice among participants were analyzed using number, percentage, and mean. Results At baseline, knowledge was limited, attitude was positive, while the practice was poor regarding oral health care during pregnancy in pregnant women belonging to different socioeconomic groups. After oral health education and blanket referral, at 28th week of gestation, knowledge regarding oral health care improved drastically, attitude toward oral health became more positive, whereas practice did not change much among all the pregnant women belonging to different socioeconomic groups, probably indicating sociocultural influences. Conclusion Intensive oral health education during pregnancy leads to drastic improvement in knowledge and attitude. Practice, gingival health, and the number of filled teeth also improved to some extent. Clinical significance Regular oral health education programs should be conducted at community level among pregnant woman to reduce the burden of oral diseases.

Abstract:

The ability to recognize the concept of early numbers in early childhood is very important to develop so that children are ready to take part in learning mathematics at a higher level. This study aims to determine the effect of mathematics learning approaches and self-regulation to recognize the concept of early numbers ability in kindergarten. The study used an experimental method with a treatment design by level 2x2. The sample used was 32 children. Score data, ability to recognize number concepts, analyzed and interpreted. The results showed that: (1) The Realistic Mathematics Education approach is better than the Open Ended Approach in improving the ability to recognize children's number concepts; (2) There is an interaction effect between mathematics learning approaches and Self-Regulation to recognize the concept of early numbers ability; (3) The Realistic Mathematics Education approach is more suitable for children with high self-regulation, (4) The Open Ended approach is more suitable for children with low self-regulation. Subsequent experiments are expected to find mathematics learning approaches for children whose self-regulation is low on recognizing the concept of early numbers ability.

Abstract:

Lithium-ion batteries (LIBs) are considered one of the best candidates to meet the skyrocketing demand for high energy density energy storage systems that was sparked by increasing popularity of portable electronics, electro-mobility and the necessary shift towards renewable energy sources.1 While the demand for energy storage systems rises rapidly, research moves forward rather sluggishly due to the complex interplay between the various active and inactive materials of a battery. One of the bottlenecks is the large time requirement and limited knowledge gain of typical, sequential experiments where one experiment is performed after the other. To mitigate this limitation, high-throughput experimentation (HTE) setups have been designed, where multiple experiments are performed in parallel rather than in sequence. Although they are common in other fields of research, high-throughput methods have not been widely adopted in battery research yet.2 Nevertheless, once a HTE setup is established, the bottleneck tends to move from the experiment to the data processing and analysis. Suitable tools to circumvent this are modern machine learning (ML) techniques, recognized as invaluable tools for accelerated material development. In most studies conducted for LIBs, only a limited number of electrolyte formulations is considered for a given set of individual electrolyte components due to aforementioned limitations of experimental capabilities. In this work, we have employed a unique HTE setup that is capable of applying electrochemical impedance spectroscopy (EIS) to 96 liquid electrolytes in a broad temperature range in parallel to study one of the fundamental bulk properties of liquid electrolytes; the ionic conductivity. Two large datasets of ionic conductivities were acquired for electrolytes consisting of lithium hexafluorophosphate (LiPF6), ethylene carbonate (EC), ethyl methyl carbonate (EMC) and either vinylene carbonate (VC) or propylene carbonate (PC) in the temperature range of -30 to 60 °C. Conducting salt concentration as well as solvent ratios were varied in wide ranges and experimental results bundled with all necessary metadata in an in-house developed .json file format for each individual experiment. More than 5000 individual conductivity values have been determined for 128 different electrolyte formulations in total. The conductivity datasets were used by our project partners in different ML approaches. Linear and Gaussian process regression were used to unravel the impact of individual electrolyte components on the ionic conductivity.3 Symbolic regression was used to discover an equation that directly models the conductivity based on the electrolyte formulation and has some common features with the empirical Debye-Hückel-Onsager equation.4 Active learning was used to improve an initial predictive model with as little additional experiments as possible in order to generate an accurate model for a given dataset.5 The presented work serves as a proof of concept in a system where the relation between parameters and observable are comparatively simple and is the foundation for applying similar principles of data processing, metadata handling and ML application to more complex experiments like galvanostatic cycling.

Abstract:

Представлен обзор, касающийся применения твердых дисперсных систем в фармации. Рассмотрены основные методы получения твердых дисперсий. Метод «удаления растворителя» является наиболее простым: в растворителе растворяют лекарственного вещества и носитель с его последующим выпариванием. Метод сплавления заключается в нагревании смеси лекарственного вещества с носителем выше температуры плавления с последующим отверждением при быстром охлаждении. Метод совместного измельчения основан на совместном использовании энергии сжатия, сдвига и трения для перевода находящегося в твердом состоянии лекарственного вещества и носителя в аморфное состояние. Метод «замешивания» является разновидностью метода совместного измельчения. В данном случае растворитель выполняет одновременно несколько функций: растворяет один из компонентов, а также проникает в микротрещины кристаллов другого компонента, оказывая расклинивающее действие и способствуя измельчению и взаимопроникновению одного вещества в поры другого. Метод с использованиемагентов, стабилизирующих аморфное состояние лекарственного вещества, заключается в смешивании следующих компонентов: умеренно растворимого лекарственного вещества, агента, индуцирующего переход системы в аморфное состояние и агента, стабилизирующего ее аморфное состояние. Полученная смесь подвергается термической или механохимической обработке. Для получения твердых дисперсных систем также используются комбинации методов. Приведены примеры полимеров и веществ не полимерной природы, используемых в качестве носителей в твердых дисперсных системах. Изучены работы авторов, посвящённые созданию и исследованиютвердых дисперсий различных фармацевтических субстанций, а также лекарственных форм, полученных на основе данных твердых дисперсий.

Abstract:

ABSTRACTBackground: Corona Virus Disease 2019 (COVID-19) is an infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov2). The COVID-19 pandemic severely limits the community environment, one of which is the limitation of dental and oral health services. The wide spread of the COVID-19 virus has caused many people to feel afraid to have their teeth checked in the midst of a pandemic, thus affecting the motivation and interest of the public to visit the dentist's practice. Objective: This study aims to determine the relationship between motivation and public interest in visiting the dentist during the COVID-19 pandemic in Sungai Miai Village. Methods: This study used an analytic observational research with a cross sectional design. The subject of this research is the Sungai Miai Village Community aged 20-55 years using a sampling technique by means of cluster random sampling totaling 113 people. Results: The results of the analysis using the Gamma test to determine the relationship between motivation and interest in visiting the dentist during the COVID-19 pandemic obtained a significant value of 0.009 (<0.05) with a correlation value of -0.52 Conclusion: There is a relationship between motivation to visit the practice dentists and interest in visiting a dentist practice with a moderate correlation strength.

Abstract:

Collisionless shocks are frequently analysed using the magnetohydrodynamics (MHD) formalism, even though MHD assumes a small mean free path. Yet, isotropy of pressure, the fruit of binary collisions and assumed in MHD, may not apply in collisionless shocks. This is especially true within a magnetized plasma, where the field can stabilize an anisotropy. In a previous article (Bret & Narayan, J. Plasma Phys., vol. 88, no. 6, 2022b, p. 905880615), a model was presented capable of dealing with the anisotropies that may arise at the front crossing. It was solved for any orientation of the field with respect to the shock front. Yet, for some values of the upstream parameters, several downstream solutions were found. Here, we complete the work started in Bret & Narayan (J. Plasma Phys., vol. 88, no. 6, 2022b, p. 905880615) by showing how to pick the physical solution out of the ones offered by the algebra. This is achieved by 2 means: (i) selecting the solution that has the downstream field obliquity closest to the upstream one. This criterion is exemplified on the parallel case and backed up by particle-in-cell simulations. (ii) Filtering out solutions which do not satisfy a criteria already invoked to trim multiple solutions in MHD: the evolutionarity criterion, that we assume valid in the collisionless case. The end result is a model in which a given upstream configuration results in a unique, or no downstream configuration (as in MHD). The largest departure from MHD is found for the case of a parallel shock.

Abstract:

AbstractThe aim of this paper is to give new results about factorizations of the Fibonacci numbers F n and the Lucas numbers L n. These numbers are defined by the second order recurrence relation a n+2 = a n+1+a n with the initial terms F 0 = 0, F 1 = 1 and L 0 = 2, L 1 = 1, respectively. Proofs of theorems are done with the help of connections between determinants of tridiagonal matrices and the Fibonacci and the Lucas numbers using the Chebyshev polynomials. This method extends the approach used in [CAHILL, N. D.—D’ERRICO, J. R.—SPENCE, J. P.: Complex factorizations of the Fibonacci and Lucas numbers, Fibonacci Quart. 41 (2003), 13–19], and CAHILL, N.

Abstract:

Abstract Bacteriophages and bacterial toxins are promising antibacterial agents to treat infections caused by multidrug-resistant (MDR) bacteria. In fact, bacteriophages have recently been successfully used to treat life-threatening infections caused by MDR bacteria (Schooley RT, Biswas B, Gill JJ, Hernandez-Morales A, Lancaster J, Lessor L, Barr JJ, Reed SL, Rohwer F, Benler S, et al. 2017.

Safety of bacteriophage therapy in severe Staphylococcus aureus infection. Nat Microbiol. 5(3):465–472). One potential problem with using these antibacterial agents is the evolution of resistance against them in the long term. Here, we studied the fitness landscape of the Escherichia coli TolC protein, an outer membrane efflux protein that is exploited by a pore forming toxin called colicin E1 and by TLS phage (Pagie L, Hogeweg P. 1999.

Microbiol Mol Biol Rev. 71(1):158–229). By systematically assessing the distribution of fitness effects of ∼9,000 single amino acid replacements in TolC using either positive (antibiotics and bile salts) or negative (colicin E1 and TLS phage) selection pressures, we quantified evolvability of the TolC. We demonstrated that the TolC is highly optimized for the efflux of antibiotics and bile salts. In contrast, under colicin E1 and TLS phage selection, TolC sequence is very sensitive to mutations. Finally, we have identified a large set of mutations in TolC that increase resistance of E. coli against colicin E1 or TLS phage without changing antibiotic susceptibility of bacterial cells. Our findings suggest that TolC is a highly evolvable target under negative selection which may limit the potential clinical use of bacteriophages and bacterial toxins if evolutionary aspects are not taken into account.

Define the generalized Narayana number $N(d,n,k)$ to count the paths in ${\cal C}(d,n)$ with ${\rm asc}(P)=k$. We consider the derivation of a formula for $N(d,n,k)$, implicit in MacMahon's work. We examine other statistics for $N(d,n,k)$ and show that the statistics ${\rm asc}$ and ${\rm des}-d+1$ are equidistributed. We use Wegschaider's algorithm, extending Sister Celine's (Wilf-Zeilberger) method to multiple summation, to obtain recurrences for $N(3,n,k)$. We introduce the generalized large Schröder numbers $(2^{d-1}\sum_k N(d,n,k)2^k)_{n\ge1}$ to count constrained paths using step sets which include diagonal steps.

Abstract:

Background and objective: Nephropathy is the major cause of end-stage renal disease (ESRD) in type 2 diabetes mellitus (T2DM). Delay in identification and management of nephropathy in T2DM may cause development of ESRD. An increased level of serum ferritin plays a role in the pathogenesis of chronic kidney disease (CKD) in T2DM. Hence, the present study intended to assess the level of serum ferritin in renal dysfunction in patients with T2DM. Material and methods: This was a retrospective study with 81 T2DM patients with and without nephropathy. They were categorized into two groups. Group-1 consisted of 46 T2DM cases without nephropathy and remaining 35 with nephropathy.The clinical and biochemical parameters such as blood glucose, urea, creatinine, iron, ferritin, transferrin, total iron binding capacity (TIBC), and haemoglobin were measured by standard methods, and estimated glomerular filtration rate (eGFR) by MDRD formula. Results: Significantly (p<0.05) elevated level of serum ferritin along with urea and creatinine was found in patients with T2DM with nephropathy.A significant positive correlation (r = 0.37) of serum ferritin and negative correlation (r = - 0.852) of eGFR with creatinine were found. It indicated that ferritin could be a good marker to monitor kidney function in T2DM. Conclusion: Apart from eGFR and serum creatinine, raised serum ferritin level was a good indicator of renal dysfunction in T2DM patients and might play an important role in renal dysfunction in early stage diabetic nephropathy.

Abstract:

Photo by Ishan @seefromthesky on Unsplash ABSTRACT A strike to highlight the plight facing contract doctors which has been proposed has received mixed reactions from those within the profession and the public. This unprecedented nationwide proposal has the potential to cause real-world effects, posing an ethical dilemma. Although strikes are common, especially in high-income countries, these industrial actions by doctors in Malaysia are almost unheard of. Reviewing available evidence from various perspectives is therefore imperative to update the profession and the complexity of invoking this important human right. INTRODUCTION Contract doctors in Malaysia held a strike on July 26, 2021. COVID-19 cases are increasing in Malaysia. In June, daily cases ranged between 4,000 to 8,000 despite various public health measures. The R naught, which indicates the infectiousness of COVID-19, remains unchanged. During the pandemic, health care workers (HCWs) have been widely celebrated, resulting in a renewed appreciation of the risks that they face.[1] The pandemic has exposed flawed governance in the public healthcare system, particularly surrounding the employment of contract doctors. Contract doctors in Malaysia are doctors who have completed their medical training, as well as two years of internship, and have subsequently been appointed as medical officers for another two years. Contract doctors are not permanently appointed, and the system did not allow extensions after the two years nor does it offer any opportunity to specialize.[2] Last week, Parliament did decide to offer a two-year extension but that did not hold off the impending strike.[3] In 2016, the Ministry of Health introduced a contract system to place medical graduates in internship positions at government healthcare facilities across the country rather than placing them in permanent posts in the Public Service Department. Social media chronicles the issues that doctors in Malaysia faced. However, tensions culminated when and contract doctors called for a strike which ended up taking place in late July 2021. BACKGROUND Over the past decade, HCW strikes have arisen mostly over wages, work hours, and administrative and financial factors.[4] In 2012, the British Medical Association organized a single “day of action” by boycotting non-urgent care as a response to government pension reforms.[5] In Ireland, doctors went on strike for a day in 2013 to protest the austerity measures implemented by the EU in response to the global economic crisis. It involved a dispute over long working hours (100 hours per week) which violated EU employment laws and more importantly put patients’ lives at risk.[6] The strike resulted in the cancellation of 15,000 hospital appointments, but emergencies services were continued. Other major strikes have been organized in the UK to negotiate better pay for HCWs in general and junior doctors’ contracts specifically.[7] During the COVID-19 pandemic, various strikes have also been organized in Hong Kong, the US, and Bolivia due to various pitfalls in managing the pandemic.[8] A recent strike in August 2020 by South Korean junior doctors and medical students was organized to protest a proposed medical reform plan which did not address wage stagnation and unfair labor practices.[9] These demands are somewhat similar to the proposed strike by contract doctors in Malaysia. As each national health system operates within a different setting, these strikes should be examined in detail to understand the degree of self-interest involved versus concerns for patient’s welfare. l. The Malaysia Strike An anonymous group planned the current strike in Malaysia. The group used social media, garnering the attention of various key stakeholders including doctors, patients, government, and medical councils.[10] The organizers of the strike referred to their planned actions as a hartal. (Although historically a hartal involved a total shutdown of workplaces, offices, shops, and other establishments as a form of civil disobedience, the Malaysian contract doctors pledged no disturbance to healthcare working hours or services and intend a walk-out that is symbolic and reflective of a strike.)[11] The call to action mainly involved showing support for the contract doctors with pictures and placards. The doctors also planned the walk-out.[12] Despite earlier employment, contract medical doctors face many inequalities as opposed to their permanent colleagues. These include differences in basic salary, provisions of leave, and government loans despite doing the same job. The system disadvantages contract doctors offering little to no job security and limited career progression. Furthermore, reports in 2020 showed that close to 4,000 doctors’ contracts were expected to expire by May 2022, leaving their futures uncertain.[13] Some will likely be offered an additional two years as the government faces pressure from the workers. Between December 2016 and May 2021, a total of 23,077 contract doctors were reportedly appointed as medical officers, with only 789 receiving permanent positions.[14] It has been suggested that they are appointed into permanent positions based on merit but the criteria for the appointments remain unclear. Those who fail to acquire a permanent position inevitably seek employment elsewhere. During the COVID-19 pandemic, there have been numerous calls for the government to absorb contract doctors into the public service as permanent staff with normal benefits. This is important considering a Malaysian study that revealed that during the pandemic over 50 percent of medical personnel feel burned out while on duty.[15] This effort might be side-lined as the government prioritizes curbing the pandemic. As these issues remain neglected, the call for a strike should be viewed as a cry for help to reignite the discussions about these issues. ll. Right to strike The right to strike is recognized as a fundamental human right by the UN and the EU.[16] Most European countries also protect the right to strike in their national constitutions.[17] In the US, the Taft-Hartley Act in 1947 prohibited healthcare workers of non-profit hospitals to form unions and engage in collective bargaining. But this exclusion was repealed in 1947 and replaced with the requirement of a 10-day advanced written notice prior to any strike action.[18] Similarly, Malaysia also recognizes the right to dispute over labor matters, either on an individual or collective basis. The Industrial Relations Act (IRA) of 1967[19] describes a strike as: “the cessation of work by a body of workers acting in combination, or a concerted refusal or a refusal under a common understanding of a number of workers to continue to work or to accept employment, and includes any act or omission by a body of workers acting in combination or under a common understanding, which is intended to or does result in any limitation, restriction, reduction or cessation of or dilatoriness in the performance or execution of the whole or any part of the duties connected with their employment” According to the same act, only members of a registered trade union may legally participate in a strike with prior registration from the Director-General of Trade Unions.[20] Under Section 43 of the IRA, any strike by essential services (including healthcare) requires prior notice of 42 days to their employer.[21] Upon receiving the notice, the employer is responsible for reporting the particulars to the Director-General of Industrial Relations to allow a “cooling-off” period and appropriate action. Employees are also protected from termination if permitted by the Director-General and strike is legalized. The Malaysian contract healthcare workers’ strike was announced and transparent. Unfortunately, even after legalization, there is fear that the government may charge those participating in the legalized strike.[22] The police have announced they will pursue participants in the strike.[23] Even the Ministry of Health has issued a warning stating that those participating in the strike may face disciplinary actions from the ministry. However, applying these laws while ignoring the underlying issues may not bode well for the COVID-19 healthcare crisis. lll. Effects of a Strike on Health Care There is often an assumption that doctors’ strikes would unavoidably cause significant harm to patients. However, a systematic review examining several strikes involving physicians reported that patient mortality remained the same or fell during the industrial action.[24] A study after the 2012 British Medical Association strike has even shown that there were fewer in-hospital deaths on the day, both among elective and emergency populations, although neither difference was significant.[25] Similarly, a recent study in Kenya showed declines in facility-based mortality during strike months.[26] Other studies have shown no obvious changes in overall mortality during strikes by HCWs.[27] There is only one report of increased mortality associated with a strike in South Africa[28] in which all the doctors in the Limpopo province stopped providing any treatment to their patients for 20 consecutive days. During this time, only one hospital continued providing services to a population of 5.5 million people. Even though their data is incomplete, authors from this study found that the number of emergency room visits decreased during the strike, but the risks of mortality in the hospital for these patients increased by 67 percent.[29] However, the study compared the strike period to a randomly selected 20-day period in May rather than comparing an average of data taken from similar dates over previous years. This could greatly influence variations between expected annual hospital mortality possibly due to extremes in weather that may exacerbate pre-existing conditions such as heart failure during warmer months or selecting months with a higher incidence of viral illness such as influenza. Importantly, all strikes ensured that emergency services were continued, at least to the degree that is generally offered on weekends. Furthermore, many doctors still provide usual services to patients despite a proclaimed strike. For example, during the 2012 BMA strike, less than one-tenth of doctors were estimated to be participating in the strike.[30] Emergency care may even improve during strikes, especially those involving junior doctors who are replaced by more senior doctors.[31] The cancellation of elective surgeries may also increase the number of doctors available to treat emergency patients. Furthermore, the cancellation of elective surgery is likely to be responsible for transient decreases in mortality. Doctors also may get more rest during strike periods. Although doctor strikes do not seem to increase patient mortality, they can disrupt delivery of healthcare.[32] Disruptions in delivery of service from prolonged strikes can result in decline of in-patient admissions and outpatient service utilization, as suggested during strikes in the UK in 2016.[33] When emergency services were affected during the last strike in April, regular service was also significantly affected. Additionally, people might need to seek alternative sources of care from the private sector and face increased costs of care. HCWs themselves may feel guilty and demotivated because of the strikes. The public health system may also lose trust as a result of service disruption caused by high recurrence of strikes. During the COVID-19 pandemic, as the healthcare system remains stretched, the potential adverse effects resulting from doctor strikes remain uncertain and potentially disruptive. In the UK, it is an offence to “willfully and maliciously…endanger human life or cause serious bodily injury.”[34] Likewise, the General Medical Council (GMC) also requires doctors to ensure that patients are not harmed or put at risk by industrial action. In the US, the American Medical Association code of ethics prohibits strikes by physicians as a bargaining tactic, while allowing some other forms of collective bargaining.[35] However, the American College of Physicians prohibits all forms of work stoppages, even when undertaken for necessary changes to the healthcare system. Similarly, the Delhi Medical Council in India issued a statement that “under no circ*mstances doctors should resort to strike as the same puts patient care in serious jeopardy.”[36] On the other hand, the positions taken by the Malaysian Medical Council (MMC) and Malaysian Medical Association (MMA) on doctors’ strikes are less clear when compared to their Western counterparts. The MMC, in their recently updated Code of Professional Conduct 2019, states that “the public reputation of the medical profession requires that every member should observe proper standards of personal behavior, not only in his professional activities but at all times.” Strikes may lead to imprisonment and disciplinary actions by MMC for those involved. Similarly, the MMA Code of Medical Ethics published in 2002 states that doctors must “make sure that your personal beliefs do not prejudice your patients' care.”[37] The MMA which is traditionally meant to represent the voices of doctors in Malaysia, may hold a more moderate position on strikes. Although HCW strikes are not explicitly mentioned in either professional body’s code of conduct and ethics, the consensus is that doctors should not do anything that will harm patients and they must maintain the proper standard of behaviors. These statements seem too general and do not represent the complexity of why and how a strike could take place. Therefore, it has been suggested that doctors and medical organizations should develop a new consensus on issues pertaining to medical professional’s social contract with society while considering the need to uphold the integrity of the profession. Experts in law, ethics, and medicine have long debated whether and when HCW strikes can be justified. If a strike is not expected to result in patient harm it is perhaps acceptable.[38] Although these debates have centered on the potential risks that strikes carry for patients, these actions also pose risks for HCWs as they may damage morale and reputation.[39] Most fundamentally, strikes raise questions about what healthcare workers owe society and what society owes them. For strikes to be morally permissible and ethical, it is suggested that they must fulfil these three criteria:[40] a. Strikes should be proportionate, e., they ‘should not inflict disproportionate harm on patients’, and hospitals should as a minimum ‘continue to provide at least such critical services as emergency care.’ b. Strikes should have a reasonable hope of success, at least not totally futile however tough the political rhetoric is. c. Strikes should be treated as a last resort: ‘all less disruptive alternatives to a strike action must have been tried and failed’, including where appropriate ‘advocacy, dissent and even disobedience’. The current strike does not fulfil the criteria mentioned. As Malaysia is still burdened with a high number of COVID-19 cases, a considerable absence of doctors from work will disrupt health services across the country. Second, since the strike organizer is not unionized, it would be difficult to negotiate better terms of contract and career paths. Third, there are ongoing talks with MMA representing the fraternity and the current government, but the time is running out for the government to establish a proper long-term solution for these contract doctors. One may argue that since the doctors’ contracts will end in a few months with no proper pathways for specialization, now is the time to strike. However, the HCW right to strike should be invoked only legally and appropriately after all other options have failed. CONCLUSION The strike in Malaysia has begun since the drafting of this paper. Doctors involved assure that there will not be any risk to patients, arguing that the strike is “symbolic”.[41] Although an organized strike remains a legal form of industrial action, a strike by HCWs in Malaysia poses various unprecedented challenges and ethical dilemmas, especially during the pandemic. The anonymous and uncoordinated strike without support from the appropriate labor unions may only spark futile discussions without affirmative actions. It should not have taken a pandemic or a strike to force the government to confront the issues at hand. It is imperative that active measures be taken to urgently address the underlying issues relating to contract physicians. As COVID-19 continues to affect thousands of people, a prompt reassessment is warranted regarding the treatment of HCWs, and the value placed on health care.

Abstract:

AbstractObjective. To describe the effects of wearing individual protection equipment against biological hazard when performing a simulated resuscitation.Methods. Uncontrolled quasi-experimental study involving 47 volunteers chosen by random sampling stratified by sex and professional category. We determined vital signs, anthropometric parameters and baseline lactate levels; subsequently, the volunteers put on level D individual protection equipment against biological hazard and performed a simulated resuscitation for 20 minutes. After undressing and 10 minutes of rest, blood was extracted again to determine lactate levels. Metabolic fatigue was defined as a level of lactic acid above 4 mmol/L at the end of the intervention.Results. 25.5% of the participants finished the simulation with an unfavorable metabolic tolerance pattern. The variables that predict metabolic fatigue were the level of physical activity and bone mass -in a protective formand muscle mass. People with a low level of physical activity had ten times the probability of metabolic fatigue compared to those with higher levels of activity (44% versus 4.5%, respectively).Conclusion. Professionals who present a medium or high level of physical activity tolerate resuscitation tasks better with a level D individual biological protection suit in a simulated resuscitation.Descriptors: cardiopulmonary resuscitation; personal protective equipment; anaerobic threshold; containment of biohazards; stress, physiological.How to cite this article: Martín-Rodríguez F.

Abstract:

Aligning protein-protein interaction networks from different species is a useful mechanism for figuring out orthologous proteins, predicting/verifying protein unknown functions or constructing evolutionary relationships. The network alignment problem is proved to be NP-hard, requiring exponential-time algorithms, which is not feasible for the fast growth of biological data. In this paper, we present a novel protein-protein interaction global network alignment algorithm, which is enhanced with an extended large neighborhood search heuristics. Evaluated on benchmark datasets of yeast, fly, human and worm, the proposed algorithm outperforms state-of-the-art. Furthermore, the complexity of ours is polynomial, thus being scalable to large biological networks in practice.
