Summary: Alpha-amylase plays an important role in the management of diabetes and its complications. This study explored the binding of caffeic acid and coumaric acid with alpha-amylase and their effects on the formation of advanced glycation end-products (AGEs). The results showed that both compounds could bind to alpha-amylase and inhibit the formation of AGEs. Caffeic acid exhibited stronger antiglycative activity compared to p-coumaric acid, which could be attributed to its additional -OH group and high antioxidant activity. The study also highlighted the role of hydrogen bonding in the complex formation. Molecular docking studies suggested that these compounds could be utilized in the design of antidiabetic drugs.

Summary: In this study, various parameters of oxidative stress, immune response, and abnormalities in the erythrocyte nucleus of Labeo rohita inhabiting the polluted Kshipra River, India, were measured. The heavy metal concentrations in the river water were in the order of Ni > Fe > Cd > Cr > Mn > Zn > Cu. The fish showed increased levels of antioxidant enzymes in gills, liver, and gut compared to the reference fish, but decreased levels of GST and GSH. Heavy metals also caused immunosuppression and histopathological changes in the fish. These findings highlight the potential impact of heavy metal-induced stress on fish inhabiting polluted river water and the importance of pollution control.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
