Dynamics of the nitrogen and phosphorous content in the Rybinsk Reservoir over the many-year period

open access: yesВодное хозяйство России: проблемы, технологии, управление
Annual dynamics of the biogenic elements content enables to assess the degree of the water bodies’ trophic state and the scale of their anthropogenic euthrophication. We have researched content of all biogenic elements’ forms in the Rybinsk Reservoir in

Purine Chemistry in the Early RNA World at the Origins of Life: From RNA and Nucleobases Lesions to Current Key Metabolic Routes

open access: yesChemBioChem, EarlyView.
In the nascent processes of the beginnings and evolution of life, nucleobases and especially purines, ribonucleos(t)ides and primitive RNAs have been continuously modified. A RNA‐peptide world and key metabolic pathways probably have emerged from the corresponding chemical modifications resulting from adenine deamination, purine alkylation and ...

The inhibitory effect of Yam polysaccharides on acrylamide‐induced programmed cell death in RAW 264.7 cells

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 443-457, January 2023., 2023
Acrylamide triggered macrophage cell apoptosis and autophagy and pyroptosis. ;P2X7 was of great significance in acrylamide‐induced cell death, but was mainly responsible for the regulation of autophagy and pyroptosis. Acrylamide stimulated oxidative stress via P2X7 in macrophage cells.

Machine Learning‐Assisted Pulse Electrodeposition of Copper for Enhanced Nitrate Sensing

open access: yesChemElectroChem, EarlyView.
A copper‐based electrochemical sensor was developed via pulse electrodeposition for nitrate detection, achieving high sensitivity of 9.928 μA/mM, a wide linear range of 0.1 to 20 mM, and satisfactory recoveries in real sample analysis. Additionally, machine learning models were designed to predict sensing performance based on electrodeposition ...
