Article Abstract
Atrazine (ATR) is a herbicide globally used to eliminate undesired weeds. Herbicide usage leads to various adverse effects on human health and the environment. The primary source of herbicides in humans is the food laced with the herbicides. The ATR binding to trypsin (TYP) was investigated in this study to explore its binding potential and toxicity. In vitro interaction of ATR with TYP was studied using multi-spectroscopic methods, molecular docking, and enzyme kinetics to explore the mechanism of binding for the TYP-ATR system. The TYP-ATR complex revealed binding constants (10 M), suggesting a moderate binding. The free energy for the TYP-ATR complexes was negative, suggesting a spontaneous interaction. Thermodynamic parameters enthalpy (ΔH) and entropy (ΔS) obtained positive values for the TYP-ATR system suggesting hydrophobic interactions in the binding process. Micro-environmental and conformational changes in TYP molecules were induced on interaction with ATR. Reduced catalytic activity of TYP was observed after interaction with ATR owing to the changes in the secondary structure of the TYP.

Due to the lack of timely vaccine prevention and effective drug treatment, lumpy skin disease is increasingly becoming a global epidemic, including in China. There is an urgent need to explore the pathogenic mechanism of lumpy skin disease virus (LSDV) and develop practical therapeutic approaches. The present study provides concrete evidence for the simultaneous induction and activation of nuclear ATM-mediated double-strand break and ATR kinase-dependent single-strand break signaling cascades during LSDV replication in the cytoplasm.

The increasing prevalence of respiratory disorders highlights the urgent need for effective mucosal vaccines that elicit targeted immune responses at pathogen entry sites. However, the advancement of mucosal vaccines is limited by challenges in antigen delivery and overcoming mucosal immune tolerance. In this study, we developed a gene delivery platform using chitosan functionalized with lactobionic acid (LA) to enhance targeting of antigen-presenting cells and to form stable DNA polyplexes with high transfection efficiency.

Iguratimod (IGU) is a novel anti-rheumatic drug, which has anti-inflammatory effects, inhibits bone destruction, and promotes bone formation. However, the gastrointestinal side-effects caused by oral tablets of IGU pose a challenge. This study aimed to develop an IGU transdermal patch for Rheumatoid Arthritis (RA) through ion-pair and chemical penetrant strategies to improve the therapeutic efficacy.
