Abstract
Searching for a universal trend by the same tuning method in different high-temperature superconductors with a similar crystal structure is a common strategy to find clues for a better understanding the superconducting mechanism in a unified way. It is known that the hole-doped bismuth-oxide Ba1-xKxBiO3 possesses a similar perovskite structure to that of the hole-doped copper-oxide (cuprate) superconductors but also holds a comparatively high superconducting transition temperature. In this study, we report the first observation of the pressure-induced quantum phase transition (QPT) from superconducting to insulating states in a series of Ba1-xKxBiO3 single-crystal samples. A similar QPT has also been observed recently in the compressed cuprate superconductors1. Significantly, we found that the QPT observed in Ba1-xKxBiO3 is intriguingly associated with the valence change of the Bi ions in the material. These results lead us to propose that the pressure-induced valence change from Bi3+ to Bi5+ destroys the hole-doping effect on stabilizing the conductivity and corresponding superconductivity. By comparing the high-pressure behaviors observed in these two kinds of oxides, we identified another prominent feature shared by them - the more the hole-doping concentration, the higher the critical pressure required for driving the QPT.

Published: August 2023

Abstract
Background: Poor oral health in children highlights the need for prevention and effective interventions. During late childhood and adolescence, peer relationships can play a vital role in adopting and maintaining positive health behaviours.
Aim: To explore the change in oral health outcome measures of school-based student peer-led oral health interventions to promote oral health compared to other modes of delivery.
Methods: Adhering to PRISMA guidelines, a search strategy was developed, piloted, and run in four electronic databases: Medline via Ovid, Web of Science, CINAHL via EBSCO, and CENTRAL (Cochrane Central Register of Controlled Trials) using key concepts of peer, oral health and adolescent in the school context. Methodological quality was assessed using QuaDs quality assessment tool. All articles were independently screened by two researchers and data was analysed using narrative data synthesis.
Results: There were 7572 identified, 24 studies progressed to full-text review, ten studies met the eligibility criteria and were included in the review. Only six studies based their interventions on psychological & behavioural theory. Intervention delivered by peers showed improvements in both clinical and self-reported outcomes when compared to other delivery methods (e.g., professionals). Quality of included studies was reported according to QuaDs guidance.
Conclusion: Peer-led interventions were more effective in improving oral health status and behaviours when compared to other modes of delivery. Future research should assess if a bi-directional impact of peer-led interventions can be seen. Specifically, if there is added value for peer-leader's oral behaviours.

Abstract
Background
Disparities in posthospitalization outcomes for people with chronic medical conditions and insured by Medicaid are well documented, yet interventions that mitigate them are lacking. Prevailing transitional care interventions narrowly target people over age 65, with specific disease processes, or limitedly focus on individual-level behavioral change such as self-care or symptom management, thus failing to adequately provide a holistic approach to ensure an optimal post-hospital care continuum. The current study evaluates the implementation of THRIVE – an evidence-based, equity-focused clinical pathway that supports Medicaid-insured individuals with multiple chronic conditions transitioning from hospital to home by focusing on the social determinants of health and systemic and structural barriers in health care delivery. THRIVE services include coordinating care, standardizing interdisciplinary communication, and addressing unmet clinical and social needs following hospital discharge.
Methods
Type I Hybrid Effectiveness-Implementation Stepped-Wedge Cluster Randomized Trial
Discussion
The implementation and evaluation of the THRIVE clinical pathway will identify clinical supports and practice factors that influence success.

Abstract
No systematic methods exist for triaging outpatients with serious conditions. Our previous pilot study showed that the National Early Warning Score (NEWS) could predict admissions and unexpected intensive care unit (ICU) transfers in rapid response system-activated outpatients. The Visensia Score Index (VSI) is another artificial intelligence-based Early Warning Score Systems that automatically collates and analyzes data from bedside monitors. This single-center retrospective cohort study aimed to investigate and compare efficacy of NEWS and VSI as a prediction tool among whole first-visit patients of our internal medicine clinic. From June 1, 2018 to November 30, 2018 at a 350-bed teaching community hospital in Japan. Patient age and sex, and physiological measurements, NEWS, VSI as well as disposition and outcomes were collected. This study included 3301 patients. There were 108 (3.3%), 16 (0.5%), and 5 (0.2%) patients admitted to the general ward, high dependency unit (HDU), and ICU, respectively. The areas under the curve (AUCs) of the NEWS for hospital admission, HDU or ICU admission, and ICU admission were 0.71 (95% CI, 0.66–0.76), 0.88 (95% CI, 0.80–0.97), and 1.00 (95% CI, 0.996–1.0), respectively. The AUCs of the VSI for admission, HDU or ICU admission, and ICU admission were 0.66 (95% CI, 0.60–0.71), 0.82 (95% CI, 0.71–0.93), and 0.97 (95% CI, 0.96–0.98), respectively. The AUC of the NEWS was significantly superior to that of the VSI for hospital (p = 0.03) and ICU admission (p < 0.01). The NEWS could triage patients with serious conditions in an outpatient setting.

Abstract
Prodigiosin finds tremendous application in the food industry owing to its physicochemical and non-toxic attributes. In the present investigation, microbial production of food color (prodigiosin) was done by Serratia marcescens NCIM 5246 under solid-state fermentation (SSF). For economical prodigiosin yield, initial substrate screening was conducted using agro-waste such as rice bran, wheat bran, orange peel powder, green gram husk and cane molasses. A maximum pigment yield of 1059.67 ± 1.53 µg/L was observed on wheat bran media. Further, Taguchi Design of the experiment (DOE) using Qualitek-4 software with bigger is better as quality attributes was done for process optimization. The Taguchi (DOE) comprised five independent variables, i.e., pH, temperature, substrate concentration, trace metal concentration, and inoculum size at two levels. The software deduced independent variables’ individual and interactive effects on product yield by performing an L8 orthogonal array (OA). The output variable (prodigiosin yield) was improved based on the S/N ratio. Under optimized cultural conditions maximum prodigiosin yield of 1320.2 ± 20 µg/L was obtained. The expected prodigiosin yield of 1386.60 µg/L showed a 95% resemblance with the actual yield, showed model validation, and 24.57% improvement in overall yield. The extracted pigment was purified by TLC and was characterized as prodigiosin by absorption spectroscopy and FTIR.

Abstract

A new lipid system broadening the capacity of antigen carriage, including mRNA and protein, is established, and an assembled virus-like-structure (VLS) encapsulated mRNA of S1 protein from XBB.1 and loaded S1 protein from omicron BA.1 on the surface is identified. This characterized VLS enables to specifically augment mRNA expression in human respiratory epithelial cells and macrophages via its loaded S1 protein on the surface interacting with ACE2 or DC-SIGN molecules of cells. It also archives effective mRNA expression in mouse dendritic cells (DCs) and macrophages via surface S1 protein binding to DC-SIGN molecules followed by the activation of DCs and macrophages in mice. The intensive antibody response against viral variants in Balb/c mice immunized by VLS was observed to be greater than those immunized by mRNA or protein vaccine alone, while ACE+/+ mice and hamsters immunized with VLS were observed to be more effective for restraining viral replication of the Omicron or Wuhan strain challenge. The mechanism of this robust immunity elicited by VLS was found being involved in the integrated effect of diverse signals from activated innate immunity to the adaptive immune system.

Abstract
In this paper, we derive the surfaces, which are called Hasimoto surfaces, corresponding to solutions of the localized induction equation for involute evolute curves. We investigate the differential geometric properties of these surfaces associated with the involute evolute curves. Moreover, we calculate the Gaussian and mean curvatures of Hasimoto surfaces in terms of curvatures of the curve pairs. Then, we determine the conditions for these surfaces' parameter curves to be the geodesics, asymptotics, and/or lines of curvature of the surface. We have demonstrated the evolutions of involute evolute curves in examples.

Abstract
Increased consumption of palm oil results in more palm oil by-products. To meet environmental sustainability, deodorizing distillate palm oil (DDPO) also calls attention to diversifying its technological or commercial application. Because of this, the present work, to present new economic-scientific alternatives for this by-product, aimed to evaluate the larvicide effect of DDPO, well as to investigate the synergistic effect of the combination of these fatty acid present in the composition of DDPO, against larvae of 3rd instar of Ae. aegypti. The DDPO larvicide assay showed a high mortality rate, with an LC50 of 6.18 µg.mL− 1 at 24 h and 8.73 µg.mL− 1 at 48 h of treatment. In addition, the results of LC50, among saturated fatty foods and between the combination of fatty acid (myristic, lauric, stearic and oleic) with palmitic acid, were met positively by second-degree polynomial regression analysis. Finally, the study of molecular docking, corroborated, as potential inhibitors of the binding of juvenile hormones. Together, the results suggest that DDPO can be a potential natural larvicide agent, making it an alternative to the excessive use of synthetic insecticides, thus minimizing its impacts on the environment and promoting new technologies for the use of this palm oil by-product.
The nature of edge pinning and vanishing friction in microscale structural superlubric graphite contact

Published: August 2023

Abstract

Structural superlubricity (SSL), a state of ultralow friction and no wear between two solid surfaces in contact, offers a fundamental solution for reducing friction and wear. Recent studies find that the edge pinning of SSL contact dominates the friction. However, its nature remains mysterious due to the lack of direct characterizations on atomic scale, especially for graphite, one of the most widely used materials for SSL. Here, for microscale graphite mesa, with detailed characterizations using atomic force microscopy, friction force microscopy, focused ion beam, high-resolution transmission electron microscope, and X-ray photoelectron spectroscopy, we unambiguously reveal the atomic structure and chemical composition of the disordered edge. The friction stress for each contact condition, namely, edge/edge, edge/surface, and surface/surface contacts are quantified, with the ratio being 104:103:1. The mechanism is revealed by full-atomic molecular dynamic simulations, which reproduce the measured friction quantitatively. Inspired by such understanding, through fabricating SixNy caps with tensile stress, we further eliminate the friction caused by the edges through disengaging the edges from the substrate. As a result, an SSL contact with ultralow friction stress of 0.1 kPa or lower is achieved directly. Such a vanishing friction is 1-2 orders lower than all the values ever reported and approaches the theoretical limit of friction for structural superlubric contact.
Impact of COVID-19 pandemic on retinopathy of prematurity services in low resource settings
Authors: Gilbert Clare 
Published: August 2023

Abstract
Background and objectives
Retinopathy of prematurity is an increasingly important cause of blindness children in low- and middle-income countries. Timely screening and treatment greatly reduce blindness. This study assessed the impact of the COVID-19 pandemic on ROP services in low- and middle-income countries.
Methods
An online survey with closed and open-ended questions in Microsoft Teams was sent to 304 ophthalmologists providing screening, treatment and/or vitreoretinal services(January 15 to March 12 2021). Categories were used to report impact on services. 28 participants were purposively selected for interview.
Results
184/201 completed forms from 32 countries were received. Two thirds of participants worked in government facilities and 45.6% were pediatric ophthalmologists. A moderate to severe impact was reported by 13% for screening, 9% for treatment and 16% for vitreoretinal surgery with some variation between government, private and not-for-profit sectors. 22% thought services would take a year to recover. Fifteen ophthalmologists from 12 countries were interviewed. Many reported fewer neonatal admissions, and several reported more ROP blind infants once restrictions lifted. Themes associated with services continuing included limited lockdown, autonomy and flexibility, commitment, advocacy and technology. Themes associated with a negative impact include fear and panic, closure of facilities, COVID infection or quarantining of health workers and parents, lack of transport and exacerbation of poverty.
Conclusions
The COVID pandemic had a very variable impact on the provision of ROP services. In some countries where the impact was great, more infants became blind from ROP. Lessons can be learnt for planning pandemic preparedness.

Published: August 2023

Abstract
Background: Ethanol infusion of the vein of Marshall (EI-VOM) has been widely used to facilitate mitral isthmus (MI) ablation. According to the literature, the success rate of achieving a bidirectional conduction block across the MI ranges from 51% to 96%, and there is no standardized strategy or method for other cardiac electrophysiologists.
Objectives: This study aimed to introduce and evaluate a novel ablation method of MI.
Methods: Consecutive patients with persistent atrial fibrillation (PeAF) that underwent catheter ablation were included. The MI ablation procedure followed a stepwise approach. In step 1, Ethanol infusion of the vein of Marshall (EI-VOM) was performed; in step 2, a "V-shape" endocardial linear ablation connecting the left inferior pulmonary vein (LIPV) to mitral annulus (MA) was performed; in step 3, earliest activation sites(EASs) near the ablation line were identified using activation mapping and reinforced ablation was performed; in step 4, precise epicardial ablation was performed, with the catheter introduced into the coronary sinus(CS) to aim at key ablation targets (KATs).
Results: 135 patients with PeAF underwent catheter ablation. Finally, 119 of them were included in the stepwise ablation method. Bidirectional conduction blocks were achieved in 117 patients (98.3%). The block rates of every step were 0%, 58.0%, 44.0%, and 92.9%, and the cumulative block rates for the four steps were 0%, 58.0%, 76.5%, and 98.3%, respectively. No patient suffered from fatal complications.
Conclusions: Our novel stepwise catheter ablation method for MI demonstrated a high bidirectional block rate with high reproducibility.
Influence of bioconvection on Williamson MHD fluid flow through extending porous surface
Authors: Basit Abdul , Zahid Muhammad , Liśkiewicz Grzegorz 
Published: August 2023

Abstract
The primary goal of this research is to investigate the consequences of Brownian motion and thermophoresis diffusion in Williamson MHD fluid flow across an extended porous sheet, as well as thermal radiation and microorganism bioconvection. Similarity functions are used to convert partial differential equations (PDEs) into equivalent ordinary differential equations (ODEs) to achieve this goal. The Runge-Kutta (RK) method with shooting strategy is then utilised to obtain the desired outcomes using a MATLAB script. In the presence of a strong magnetic parameter, the fluid velocity decreases, but it increases with mixed convection. As thermophoresis (Nt) and Brownian motion (Nb) parameters are increased, the temperature rises. The velocity field is decreased by theLewis number of bioconvection.

Published: August 2023

Abstract
Phenol is one of the important ingredients of pyrolysis oil, contributing to the high biotoxicity of pyrolysis oil. To promote the degradation and conversion of phenol during anaerobic digestion, hydro-chars with high phenol adsorption capacity were produced. The phenol adsorption capabilities of the plain hydro-char, plasma modified hydro-char at 25 ℃ (HC-NH3-P-25), and plasma modified hydro-char at 500 ℃ (HC-NH3-P-500), and their adsorption kinetics and thermodynamics were explored. Experimental results indicate that the phenol adsorption capability of HC-NH3-P-500 was the highest. The phenol adsorption kinetics of all samples followed the Pseudo-second-order equation and interparticle diffusion model, indicating that the adsorption rate of phenol was controlled by interparticle diffusion and chemistry adsorption simultaneously. By DFT calculations, π-π stacking and hydrogen bond are the main interactions for phenol adsorption. It was observed that an enriched graphite N content decreased the average vertical distance between hydro-chars and phenol in π-π stacking complex, from 3.5120 Å to 3.4532 Å, causing an increase in the negative adsorption energy between phenol and hydro-char from 13.9330 to 23.4181 kJ/mol. For hydrogen bond complex, the average vertical distance decreased from 3.4885 Å to 3.3386 Å due to the increase in graphite N content; causing the corresponding negative adsorption energy increased from 19.0233 to 19.9517 kJ/mol. Additionally, the presence of graphite N in the hydro-char created a positive diffusion region and enhanced the electron density between hydro-char and phenol. Analyses suggest that enriched graphite N contributed to the adsorption complex stability, resulting in an improved phenol adsorption capacity.

Abstract
Purpose
The extraction of essential oil from citrus fruit peel is an innovative way to make use of a valuable component that is often considered waste. This research focused on extracting essential oil from three different galgal cultivars (Punjab Galgal; PBG, Haryana Galgal; HRG, and Himachal Galgal; HPG) using various methods. The extracted oils were tested for bioactive components, which were subsequently investigated for antibacterial and antioxidant properties.
Method
The peel obtained from various fruit cultivars were examined for physicochemical and phytochemical properties. The essential oils were then extracted from peel by employing different techniques and the yield was calculated to adopt best possible method. The characterization of bioactive components in essential oils was done using gas chromatography mass spectrometry method. Finally, the essential oils were studied for antioxidant and antimicrobial properties.
Results
The pH, titratable acidity, total soluble solids, moisture, color, proteins, fat, fibers, total carotenoids, chlorophyll, and ash content of fruit peel varied across different fruit varieties. Among the methods tested for essential oil extraction, the Clevenger method demonstrated superior performance compared to supercritical fluid, steam distillation, microwave-assisted, and ultrasound-assisted extraction. The essential oils extracted from the fruit peels contained varying amounts of D-limonene, a-ocimene, a-myrcene, and a-pinene, with variations observed among different cultivars. Furthermore, all essential oils exhibited good antioxidant and antibacterial properties.
Conclusion
The utilization of essential oils as antioxidant and antimicrobial agents in foods is an effective strategy for fruit industry waste valorization, and it could also best serve as a substitute for various chemical preservatives.
