Soil is the foundation of terrestrial ecosystems and a critical resource for agricultural activities. This study investigated internal mechanism and interaction of heavy metals, pesticides (atrazine, pyrimazole and chlorpyrifos) and microplastics in soil. Specifically, certain sampling points exhibited elevated levels of individual heavy metals (Cd, Cr, Zn), exceeding the screening values, while both microplastics and pesticides demonstrated high variability, increasing the potential ecological risks.

Drought tolerance and plant growth are critical factors affecting rice yield, and identifying genes that can enhance these traits is essential for improving crop resilience and productivity. Using a () mutant of the rice variety Huanghuazhan (HHZ) generated by radiation mutagenesis, we discovered a novel gene, , which plays a dual role in plant biology: it acts as a positive regulator of growth and development, but as a negative regulator of drought resistance. The mutant displayed a marked reduction in plant growth and seed setting rate, yet exhibited an unexpected advantage in terms of drought tolerance.

Heat acclimation (HA) is widely recognized as the best measure to prevent and protect against HS. Preventive administration of oral rehydration salts III (ORSIII) and probiotics have been reported to sustain intestinal function in cases of HS.

Cohesin is a multi-subunit protein that plays a pivotal role in holding sister chromatids together during cell division. Sister chromatid cohesion 3 (SCC3), constituents of cohesin complex, is highly conserved from yeast to mammals. Since the deletion of individual cohesin subunit always causes lethality, it is difficult to dissect its biological function in both mitosis and meiosis.

Host materials with lamellar structures are a good choice for hybrid charge storage hosts (capacitor or redox type). Emerging layered transition metal carbo-chalcogenides (TMCC) with homogeneous sulfur termination are especially attractive for charge storage.

Knockout of DNAJA1 (DNAJA1‑KO) is thought to be protective against HS based on a genome‑wide CRISPR‑Cas9 screen experiment. The present study aimed to illustrate the function of DNAJA1‑KO against HS in human umbilical vein endothelial cells.

Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) carry donor-specific genetic information and have been proposed for exploring the interindividual difference in oncology drug-induced cardiotoxicity. Herein, we evaluated the inter- and intraindividual variability of iPSC-CM-related assays and presented a proof of concept to prospectively predict doxorubicin (DOX)-induced cardiotoxicity (DIC) using donor-specific iPSC-CMs.

Using density functional theory calculations, NRA pathways are evaluated on low-index crystal surfaces CuO (111), CuO (111), and Cu (111) at different pH. CuO (111), with abundant undercoordinated Cu atoms on the surface, shows easier adsorption of NO than Cu (111) or CuO (111).

Recently, tea varieties with variations in leaf color have been widely used in agriculture production due to their potential advantages in terms of tea quality. Numerous studies have used genome, transcriptome, metabolome, proteome, and lipidome methods to uncover the causes of leaf color variations and investigate their impacts on the accumulation of crucial bioactive metabolites in tea plants.

Methods: Seventy-two male SD-grade rats were selected to establish a DM model by intraperitoneal injection of streptozotocin (STZ), and randomly divided into a control group (blank control group), a DM group (diabetic model group), a DM+miR-NC inhibitor group (miR-193a inhibition negative control group), a DM+miR-193a inhibitor group (miR-193a inhibitor group), DM+miR-NC mimic group (miR-193a overexpression negative control group), DM+miR-193a mimic group (miR-193a overexpression group), with12 rats in each group.
Results: The miR-193a expression, apoptosis rate, and Bax, Caspase3, and Caspase9 protein expression levels were elevated, and Bcl-2 protein expression was decreased in the retinal tissues of DM rats and high glucose-induced rat retinal neuronal cells, while miR-193a inhibitors reversed these processes.
