Baikal endemic and Palearctic species of caddisflies (Trichoptera) build cases from microplastics
Acta Biologica SibiricaPollution of freshwater ecosystems by microplastics is a serious problem. Many studies are related to the pelagic zone and the organisms living in it. However, benthic organisms are most susceptible to this problem in aquatic ecosystems.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Arginase Inhibitor in the Pharmacological Correction of Endothelial Dysfunction
International Journal of Hypertension, 2011 This paper is about a way of correction of endothelial dysfunction with the inhibitor of arginase: L-norvaline. There is an imbalance between vasoconstriction and

Advanced Functional Materials, EarlyView.There is a significant need for biomaterials with well‐defined stability and bioactivity to support tissue regeneration. In this study, we developed a tunable microgel platform that enables the decoupling of stiffness from porosity, thereby promoting bone regeneration.

Microplastics in Sediments of the Littoral Zone and Beach of Lake Baikal
Limnological ReviewMost studies on microplastic pollution in aquatic ecosystems have focused on the quantitative and qualitative assessment of particles in surface waters. However, the highest concentrations and accumulation of microplastic particles are observed in bottom

Advanced Functional Materials, EarlyView.This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...
