In 2020, the National Fire Agency of the Republic of Korea surveyed 50,527 firefighters and identified 242 burn-related incidents. The body parts affected by these burns were the hands (28.51%), ears (10.74%), and neck (10.33%), with hands and facial areas accounting for ∼50% of all burns. This trend implies that gloves and hoods do not provide sufficient protection against burns. Firefighters alternate between activity and rest during firefighting operations to enhance mission efficiency. However, the accumulated heat in their hood and gloves from these repeated cycles has not been considered thus far. This study investigated thermal accumulation patterns based on the moisture content of hoods and gloves, reflecting repeated cycles of work and rest for firefighters. Consequently, heat accumulation occurred in a dry state in both the hood and gloves, and the degree of heat storage was higher in the hood. The glove stored heat even when wet because of its multilayer structural characteristics. These results suggest that repeated activities (work-rest) with gloves and hoods under dry/wet conditions can generate residual heat and heat accumulation, causing burns on the hand and face. This study clearly demonstrated the impact of the moisture conditions of gloves and hoods in repetitive situations where they are exposed to relatively low levels of heat radiation and are then subject to rest periods. The results of this study are expected to be valuable in designing new protective gear to prevent burn injuries and developing efficient firefighting tactics.</p>","PeriodicalId":56061,"journal":{"name":"Science Progress","volume":"108 1","pages":"368504251315803"},"PeriodicalIF":2.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11752760/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143017038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, obesity has turned into one of the most health public problems worldwide, which highlights the urgent need for new and safe treatments. Obesity is mainly related to excessive fat accumulation; therefore, proteins participating in white adipose tissue increase and dysfunction are considered pertinent and attractive targets for developing new methods that can help with body weight control. In this context, virtual screening of libraries containing a large number of molecules represents a valuable strategy for the identification of potential anti-adipogenic compounds with reduced costs and time production. Here, we review the scientific literature about the prediction of new ligands of specific proteins through molecular docking and virtual screening of chemical libraries, with the aim of proposing new potential anti-adipogenic molecules. First, we present the targets related to adipogenesis and adipocyte functions that were selected for the following studies: PPARγ, Crif1, SIRT1, ERβ, PC1, FTO, Mss51, and FABP4. Then, we describe the obtention of new ligands according to the characteristics of the virtual screening approach, i.e. a structure-based drug design (SBDD) or a ligand-based drug design (LBDD). Finally, the critical analysis of these computational strategies and the corresponding results points out the necessity of combining computational and <i>in vitro</i> or <i>in vivo</i> assays for the identification of effective new anti-adipogenic molecules for obesity control.

Cases were divided into pre-COVID-19 and post-COVID-19 periods. Chi-square tests assessed differences in oral pathologies incidence, while logistic regression analyzed associations with COVID-19 status and corticosteroid use.ResultsMucormycosis cases demonstrated a significant increase from 3 (pre-COVID-19) to 23 (post-COVID-19), with 65.22% of post-COVID-19 patients testing COVID-19-positive. A significant increase in mucormycosis severity was observed after COVID-19 (χ² = 14.24, p = 0.0026).

This precursor is synthesized via the condensation of o-phenylenediamine (OPD) with 4-nitrobenzaldehyde (NBA). The formation of the Schiff base involves the nucleophilic attack of OPD's amino groups on the carbonyl carbon of 4-nitrobenzaldehyde, resulting in an imine linkage essential for subsequent cyclization reactions. Cyclization of the mono Schiff base N-(4-nitrobenzyl) benzene-1,2-diamine (NBD) is a crucial step in forming the benzimidazole ring. This compound's significance lies in its structural and electronic properties, influenced by the electron-withdrawing nitro group, making it valuable in coordination chemistry, medicinal chemistry, and materials science. In coordination chemistry, metal complexes of 2-(4-nitrophenyl)-1H-benzimidazole (NBI) acts as a ligand, forming stable complexes with transition metals that exhibit enhanced catalytic activity. These metal complexes are essential for various catalytic processes, including organic transformations and polymerization reactions. In medicinal chemistry, the benzimidazole core is a common motif in biologically active compounds. The presence of the nitro group can modulate the biological activity, making derivatives of 2-(4-nitrophenyl)-1H-benzimidazole (NBI) promising candidates for antimicrobial, anticancer, and antiviral agents.
