Authors: Agrahari Shweta , Singh Satya Pal , Gupta Abhishek Kumar 
Published: July 2024

Abstract

Computational tools for studying the atomic and molecular structures of complex systems are very useful. This work uses the first principle method to investigate the structural and optoelectronic properties of a polyethylene oxide (PEO)-based solid polymer electrolyte including lithium salt (LiFSI) as an ion-conducting species. DFT has been used for the analysis of electrolyte conducting properties. The electrical band gap of the polymer electrolyte (PEO)8-LiFSI system has been quantitatively examined by density of states (DOS) studies. From electronical analysis, it is verified that (PEO)8 exhibits insulator properties with a wide band gap of 6.2797 eV, whereas the bandgap of (PEO)8-LiFSI slightly drops to 6.0028 eV. These findings suggest that the current polymer electrolyte system (PEO)8-LiFSI could be a viable option for the electrolyte in next-generation energy storage devices.

Abstract

Chemical exposures may impact human metabolism and contribute to the etiology of neurodegenerative disorders like Alzheimer’s Disease (AD). Identifying these small metabolites involves matching experimental spectra to reference spectra in databases. However, environmental chemicals or physiologically active metabolites are usually present at low concentrations in human specimens. The presence of noise ions can significantly degrade spectral quality, leading to false negatives and reduced identification rates. In response to this challenge, the Spectral Denoising algorithm removes both chemical and electronic noise. Spectral Denoising outperformed alternative methods in benchmarking studies on 240 tested metabolites. It improved high confident compound identifications at an average 35-fold lower concentrations than previously achievable. Spectral Denoising proved highly robust against varying levels of both chemical and electronic noise even with >150-fold higher intensity of noise ions than true fragment ions. For human plasma samples of AD patients that were analyzed on the Orbitrap Astral mass spectrometer, Denoising Search detected 2.3-fold more annotated compounds compared to the Exploris 240 Orbitrap instrument, including drug metabolites, household and industrial chemicals, and pesticides. This combination of advanced instrumentation with a superior denoising algorithm opens the door for precision medicine in exposome research.

Abstract

Objectives
1.5 billion people live without basic sanitation. A five-attribute index of sanitation-related quality of life (SanQoL-5) designed for economic evaluation has now been applied in six countries. After rescaling, scores range 0 (no sanitation capability) to 1 (full sanitation capability). To date, SanQoL-5 valuation has been via simple methods such as rank sum, not robust methods such as discrete choice experiment (DCE). We aimed to value the SanQoL-5 index using a DCE in urban Mozambique.
Methods
We enrolled 601 adults in the cities of Maputo and Dondo, sampling women and men equally alongside quotas for toilet type. The DCE task was a choice between two scenarios representing combinations of SanQoL-5 attribute levels (always, sometimes, never). Each respondent completed 10 tasks and a dominance test. We fitted a mixed logit model and rescaled coefficients to derive the index, with sub-group analysis by gender.
Results
The highest-valued attribute was disgust (“never feel disgusted while using the toilet”), with a SanQoL-5 index value of 0.25. The other attributes had similar values (ranging 0.18–0.19). People valued “sometimes” levels at around 60% of “never” levels. Mean SanQoL-5 by toilet type followed a gradient with Sustainable Development Goal 6 categories: “open defecation” 0.30, “unimproved” 0.45, “limited” 0.60 and “at least basic” 0.70.
Conclusions
This is the first DCE-based valuation of any index of sanitation-related quality of life, enabling the SanQoL-5 to be used in economic evaluation. Identifying sanitation service transitions associated with the greatest quality of life gains could inform more efficient resource allocation.
Valuing behavioural interventions for obesity reduction: A scoping review of economic models
Authors: McLaughlin Joanna , Sillero-Rejon Carlos , Moore Theresa HM , McLeod Hugh 
Published: July 2024

Abstract

Policymakers require health economic modelling to guide their decision-making over the choice of interventions for obesity. This scoping review was undertaken to report on the health economic models in use for estimating the value of behavioural interventions (individual or population level) for obesity reduction. Electronic databases (MEDLINE, Embase, PsycINFO, EconLit and Web of Science) were searched for publications meeting inclusion criteria from January 2015 to May 2023. Seventy-three studies were included, using 44 health economic models between them. When considered against the expert recommendations for modelling of this type, only four models (9%) met all five key elements. The element most commonly unfulfilled was the use of a microsimulation modelling approach (41%, n = 18), followed by model validation (46%, n = 20). A majority of models met each of the other elements: use of a lifetime horizon (59%, n = 26), inclusion of key health events (66%, n = 29) and a risk equation approach to event simulation (71%, n = 31). In addition, under half of the studies considered health inequalities in their reporting. Continued proliferation of models with inadequate time horizons, breadth of obesity-related health conditions, and perspectives on costs and outcomes, risks underestimation of the benefits of longer-term interventions and impacts on health inequalities.

Abstract
The High Field Strength Elements (HFSE) Ti, Nb and rare earth elements (REE) are commonly regarded as immobile during hydrothermal activity and metamorphism, making them important tracers of geological processes. Here, we report a Ti-REE-Nb-As mineralisation recently discovered in quartz, feldspar, muscovite ± biotite, fluorapatite, hematite, epidote and dravite-schorl veins hosted in quartz ± feldspar ± muscovite ± biotite gneisses from the Monte Leone nappe (Switzerland/Italy). The veins formed during prograde metamorphism and were boudinaged and/or folded during peak metamorphism under lower amphibolite facies. The mineralisation consists of megacrysts (≫ 2 cm) of allanite-(Ce) and Nb-REE-rich titanite-(I). Titanite-(I) displays prominent primary oscillatory- and sector-zonings in Y+REE and Nb. Allanite-(Ce) and titanite are also present as metamorphic minerals disseminated in the host-rock. The vein-hosted megacrysts and their host rocks have identical Nd isotope systematics, indicating that the HFSE mineralisation results from small-scale remobilisation of host-rock components.
Localised, fluid-assisted dissolution of vein-hosted allanite-(Ce), epidote, and dravite-schorl during retrograde alpine deuteric alteration resulted in cavities lined with chlorite, muscovite, hematite, and diverse REE minerals. The same fluids caused titanite-(I) to break down into a porous assemblage of acicular niobian rutile with lamellae of crichtonite-group minerals and/or hematite and a suite of REE-Nb-Ti micro-minerals. A few titanite (titanite-II) crystals preserve an intermediate stage of the dissolution-reprecipitation process. Unlike titanite-(I), they display a patchwork-like micro-texture (100 μm-sized subgrains with inhomogeneous Nb concentrations); they host lamellae of crichtonite-group minerals within cleavage planes of the parent titanite, as well as secondary Y+Nb+REE oxides and calcite along subgrain boundaries. Calcite indicates that CO2-enriched fluids promoted the destabilisation of titanite-(I). Highly localised fluid flow accounts for the common occurrence of fresh and altered allanite-(Ce) and titanite in close proximity.
The HFSE-enriched veins reveal a complex history of mobility of minor elements (Ti, Nb, REE, As ± B, Be) together with major components (Si, Al, K, Na, Fe) from the host rock, resulting in their early (prograde) concentration within the veins, and their remobilisation upon the action of oxidised CO2-bearing fluids during retrograde metamorphism. In general, crystallisation of enriched phases during prograde metamorphism may be an important step in determining the fertility of a source rock for hydrothermal HFSE deposits.

Published: July 2024

Indonesia is an archipelagic nation that has a variety of difficulties when it comes to the delivery of products and services. There are a number of challenges experienced in the field of logistics in Indonesia, including poor transportation infrastructure in a number of different places. Sustainable development is a concept that aims to find a balance between people’s needs now and their ability to meet those needs in the future. The research aimed to identify and analyze the relationship between leadership and community involvement (also known as community participation or engagement) in sustainable development in the shipping industry. The research used the Partial Least Squares-Structural Equation Model (PLS-SEM) with a sample of 103 shipping companies to analyze data. The research results show that leadership positively and significantly impacts sustainable development, confirming the importance of the leader’s role in implementing sustainable practices in company operations. Meanwhile, community involvement shows a positive but insignificant impact on sustainable development, indicating that the community needs to be reconsidered in the context of sustainable development in the shipping industry. The results also provide information for companies and leaders to strengthen sustainable development efforts by implementing more integrated policies focused on community involvement. Moreover, the research offers a chance to encourage cooperation between industrial actors and local populations. By harmonizing objectives, expectations, and actions, it is feasible to develop projects that strengthen sustainable practices within the ocean freight transportation business and promote the well-being of the communities it interacts with.

Tumor-Targeted Therapy
Authors: Zhang Ziyi , Tian Jinyuan , Xu Xiaoqing , Shi Wei , Qi Yajuan , Liu Zhanjun 
Published: July 2024

Introduction:
Polymer prodrug nanoparticles have become an emerging drug delivery
system in cancer therapy due to their high drug loading. However, their poor drug release and lack of
tumor cell targeting limit their clinical application.

Objective:
This study aimed to prepare targeted and reduction-reactive polyprodrug nanocarriers
based on curcumin (CUR) for co-delivery of doxorubicin (DOX), labeled as DOX/HAPCS NPs, and
to investigate their anticancer activity.

Methods:
The polymer was synthesized and characterized by chemical method. The drug loading
and drug release behavior of DOX and CUR in polymer nanoparticles were determined. Moreover,
the antitumor effects of polymer nanoparticles were evaluated using an MTT experiment and tumor
inhibition experiment, and the synergistic effect of co-delivered DOX and CUR was explored.

Results:
The particle size of DOX/HAPCS NPs was 152.5nm, and the potential was about -26.74
mV. The drug-carrying capacity of DOX and CUR was about 7.56% and 34.75%, respectively, indicating high drug-carrying capacity and good stability. DOX and CUR released over 90% within 24
hours in the tumor environment. Compared with free DOX, DOX/HAPCS NPs demonstrated significantly enhanced cell and tumor inhibitory effects (P<0.05) in vivo and in vitro and changed drug
distribution to avoid toxic side effects on normal tissues. The combined index showed that DOX and
CUR showed synergistic anticancer effects at a set ratio.

Conclusion:
The prepared reduction-responsive targeted polymer nanomedical DOX/HAPCS NPs
exhibited a synergistic anti-cancer effect, with high drug loading capacity and the ability to release
drugs in proportion, making it a promising polymer nanoparticle drug delivery system.

Authors: Таnygina Е. А. 
Published: July 2024

The presented study of the image of the color designation white in the minds of the representatives of modern Russian culture is a continuation of the cycle of studies of the images of the main Russian color terms from the point of view of the psycholinguistic doctrine of the word by A.A. Zalevskaya.The hypothesis of the study was the assumption that there are both individual and cultural components which influence the formation of the image of any phenomenon in the minds of the average bearer of a particular culture.The main methods used in the experimental research were free associative experiment and semantic differential. Factor and definitional analyzes were used to process the results.The material for the study was the associations obtained during free associative experiments in 2009 and 2020 as well as the results of an experiment using a semantic differential among students of Southwest State University. In order to identify a possible transformation of the image of white, the data of the Russian comparative associative dictionary by G.A. Cherkasova were analyzed.The work shows the current structure of the associative field of the Russian color term white. It also analyzes the change in the structure of the described associative field during the period since the 1970s until now. In addition, the main gender characteristics of the perception of the color white are shown, typically female and male associations in the structure of the considered AP are highlighted.The research methodology presented in the work can be successfully used in organizing various psycholinguistic and linguocultural studies. The results of the empirical research can find application not only in various branches of linguistics but also in psychology, neurophysiology, marketing and advertising.
Racial Biases Associated With Pulse Oximetry: Longitudinal Social Network Analysis of Social Media Advocacy Impact
Authors: Ahmed Wasim , Hardey Mariann , Winters Bradford David , Sarwal Aarti 
Published: July 2024

Background
Pulse oximetry is a noninvasive method widely used in critical care and various clinical settings to monitor blood oxygen saturation. During the COVID-19 pandemic, its application for at-home oxygen saturation monitoring became prevalent. Further investigations found that pulse oximetry devices show decreased accuracy when used on individuals with darker skin tones. This study aimed to investigate the influence of X (previously known as Twitter) on the dissemination of information and the extent to which it raised health care sector awareness regarding racial disparities in pulse oximetry.

Objective
This study aimed to explore the impact of social media, specifically X, on increasing awareness of racial disparities in the accuracy of pulse oximetry and to map this analysis against the evolution of published literature on this topic.

Methods
We used social network analysis drawing upon Network Overview Discovery and Exploration for Excel Pro (NodeXL Pro; Social Media Research Foundation) to examine the impact of X conversations concerning pulse oximetry devices. Searches were conducted using the Twitter Academic Track application programming interface (as it was known then). These searches were performed each year (January to December) from 2012 to 2022 to cover 11 years with up to 52,052 users, generating 188,051 posts. We identified the nature of influencers in this field and monitored the temporal dissemination of information about social events and regulatory changes. Furthermore, our social media analysis was mapped against the evolution of published literature on this topic, which we located using PubMed.

Results
Conversations on X increased health care awareness of racial bias in pulse oximetry. They also facilitated the rapid dissemination of information, attaining a substantial audience within a compressed time frame, which may have impacted regulatory action announced concerning the investigation of racial biases in pulse oximetry. This increased awareness led to a surge in scientific research on the subject, highlighting a growing recognition of the necessity to understand and address these disparities in medical technology and its usage.

Conclusions
Social media platforms such as X enabled researchers, health experts, patients, and the public to rapidly share information, increasing awareness of potential racial bias. These platforms also helped connect individuals interested in these topics and facilitated discussions that spurred further research. Our research provides a basis for understanding the role of X and other social media platforms in spreading health-related information about potential biases in medical devices such as pulse oximeters.

Published: July 2024

Background
Although COVID-19 is no longer a global health emergency, it remains pervasive in Singapore, a city-state situated in Southeast Asia, with periodic waves of infection. In addition to disease management, strong communication strategies are critical in the government’s response to the pandemic to keep the public updated and equip them in protecting themselves.

Objective
Grounded in the crisis and emergency risk communication (CERC) framework and emotional appeals, this study aimed to analyze public health communication strategies in Singapore during the COVID-19 pandemic.

Methods
Quantitative content analysis was conducted on 696 Facebook (Meta Platforms Inc) posts and 83 website articles published by Singapore-based public health institutions between January 2020 and September 2022.

Results
The results showed that increasing communication on message themes, such as inquisitive messaging and clarification, can enhance communication strategies. The use of emotional appeals also varies with time and should be carefully used as they are context-specific.

Conclusions
Theoretically, this study contributes to advancements in the CERC framework and concepts of emotional appeals by exploring the applications and changes of CERC message types and emotional appeals at different phases. The findings can provide practical guidance for authorities and communication practitioners in developing effective communication strategies.
