There is limited research on the influence of environmental variables on the interactions of biodegradable microplastics with chromium. This study reports the results of adsorption experiments with Cr and poly(lactic acid) (PLA) in synthetic aqueous solutions. It addresses the influence of the initial oxidation state, Cr(III) or Cr(VI), the effects of UV irradiation and the presence of organic matter.

Lipopolysaccharide (LPS)-neutralizing peptides are emerging as new potential therapeutic modalities to treat sepsis and skin infections. Purinergic ligand-gated ion channels (P2X receptors) play a critical role in various biological processes, including inflammation. Recent drug development efforts have significantly focused on the modulation of P2X receptors.

Objective: Our research has pinpointed the gut microbiome's role in the progression of various pathological types of non-small cell lung cancer (NSCLC). Nonetheless, the characteristics of the gut microbiome and its metabolites across different clinical stages of NSCLC are yet to be fully understood. The current study seeks to explore the distinctive gut flora and metabolite profiles of NSCLC patients across varying TNM stages.

Anaplastic thyroid carcinoma is one of the highly fatal cancers and poses a serious threat to human health. Ferroptosis has been widely studied and proved to have an important role in tumor suppression, providing new avenues for cancer therapy; glutathione peroxidase 4(GPX4) and selenoprotein thioredoxin reductase(TXNRD1) are important regulatory targets in ferroptosis.Warburg effect is one of the important energy sources for cancer hypermetabolism, and pyruvate kinase isoenzyme 2 (PKM2) is a key metabolism enzyme that is important in this effect.

Extracellular vesicles (EVs) are nanosized lipid bilayer particles released by various cellular organisms that carry an array of bioactive molecules. EVs have diagnostic potential, as they play a role in intercellular interspecies communication, and could be applied in drug delivery. In contrast to mammalian cell-derived EVs, the study of EVs from bacteria, particularly Gram-positive bacteria, received less research attention.
