Human interleukin-37 isoform 1 (IL-37b) is a key anti-inflammatory cytokine with significant therapeutic potential for inflammatory and immune-mediated disorders. However, its clinical translation is limited by poor understanding of disease-associated genetic variants and lack of an expression system for soluble production. While addressing both challenges, this study presents (a) a prioritized catalog of high-confidence, pathogenic IL-37b variants, and (b) a fusion-based expression platform for its soluble production, providing essential resources for future functional validations.

Research Background: Black garlic has been reported to have several health-promoting properties compared to fresh, raw garlic. The enzyme alliinase, which converts alliin to allicin, is deactivated at moderately high temperature, thus stripping away the typical pungent odour of fresh garlic during fermentation and rendering black garlic devoid of the typical garlic-like smell. To date, the antimicrobial activity of alliin-rich extract obtained from black garlic powder has not been reported.

Irrigation with sewage water can offer benefits such as increased crop productivity, but it also has significant drawbacks that affect crops, soil quality, and human health. Given its diverse composition of toxins, including chemicals and heavy metals, sewage water can adversely impact both soil fertility and crop health. With this in mind, the objective of this research was to evaluate the potential health risks associated with iron (Fe) in vegetables, specifically leafy and root vegetables, irrigated with wastewater, canal water, and a combination of organic and inorganic fertilizers.

Understanding solvent-induced crystallization and defect dynamics in hybrid perovskites is crucial for stable and high-efficiency solar cells. Here, we investigate the influence of DMF : DMSO solvent ratios on the nucleation, grain boundary passivation, and optoelectronic behaviors of MAPbI thin films prepared under ambient conditions. X-ray diffraction and photoluminescence analyses reveal that increasing DMSO content promotes PbI segregation, which passivates grain boundaries and modulates trap-assisted recombination.

The current investigation analyzed the population dynamics of vegetation in the severely dust-polluted environment of the stone crushing industry in the Kirana Hills of Sargodha. Data pertaining to dust levels, soil composition, and vegetation characteristics were systematically collected from all the study sites throughout the year to explore the seasonal fluctuations in the plant community structure and the underlying determinants of these variations. Heavy metal analysis revealed increased concentrations of all heavy metals at the most heavily dust-polluted sites, particularly during the winter season.

Two-dimensional (2D) materials are promising candidates for next-generation electronics, but the realization of high-performance p-type 2D field-effect transistors (FETs) has remained challenging, hindering the development of fully integrated 2D complementary metal-oxide-semiconductor (CMOS) technology. Here, we present p-type 2D FETs based on bilayer WSe synthesized via an industry-compatible metal-organic chemical vapor deposition (MOCVD) process. These devices achieve on-state current as high as 421 μA/μm at a drain voltage of 1 V and a gate overdrive voltage of 2.
