Targeting protein-ligand neosurfaces with a generalizable deep learning tool.

Molecular recognition events between proteins drive biological processes in living systems. However, higher levels of mechanistic regulation have emerged, in which protein-protein interactions are conditioned to small molecules. Despite recent advances, computational tools for the design of new chemically induced protein interactions have remained a challenging task for the field.

[Analysis of the influence of enzyme preparations produced using technological microorganisms on the microbiome and cellular immunity of rats].

The observed increase in the production of enzyme preparations (EP) using mutant and genetically modified microorganisms makes it necessary to assess their risks to consumer health. However, at present, their possible influence on the microbiome, immune status of the macroorganism has not been sufficiently studied. of the research was to assess the effect of two EP - the complex of hydrolases with proteolytic and nuclease activity from the Aspergillus oryzae RCAM 01134 mutant strain (EP1) and the neutral protease - bacillolysin and serine protease from the Bacillus subtilis-96 (VKM B-3499D) mutant strain (FP2) on the intestine microbiome and cellular immunity indices of the experimental animals.

[Correction of gut dysbiosis as a promising direction in the prevention of neuroinflammation and cognitive impairment].

In recent years new data have been obtained on the role of intestinal dysbiosis in the pathogenesis mechanisms of neuroinflammation and neurodegeneration in Alzheimer's disease (AD), as well as on the influence of dietary patterns (Mediterranean diet, MIND diet) and probiotics on the correction of dysbiosis and slowing down the development of cognitive disorders. It seems reasonable to draw the attention of practicing physicians to the need to prevent cognitive dysfunction through dietary correction, probiotics and prebiotics intake. of the research was to study the possibility of using certain dietary patterns, as well as intake of probiotics and prebiotics for the correction of dysbiosis and early prevention of cognitive dysfunction, basing on the analysis of published data on the bidirectional communication between the colon microbiota and the brain and microbiota changes in patients with cognitive dysfunction and AD.

[On the regulate tropane alkaloids in grain products].

Tropane alkaloids (TA) are metabolites of various plant species in the families Brassicaceae, Solanaceae and Erythroxylaceae. Seeds of these weeds are found in flax, soy, sorghum, millet, sunflower, buckwheat and food products obtained from them, in herbals used as a part of food supplements and herbal teas. Despite the fact that the contamination of grain seeds by various parts of weeds reduces by sorting and clean up, a certain amount of TA gets into processed foods.

[Lipoic acid: physiological role and prospects for clinical application].

α-Lipoic acid (also known as thioctic acid) is a natural vitamin-like compound. Lipoic acid contains asymmetrical carbon, which causes the presence of two possible optical isomers (enantiomers): R-lipoic acid (levogyrate isomer) and S-lipoic acid (rightspinning isomer). Lipoic acid functions as a cofactor for several important mitochondrial multienzyme complexes, enhances the uptake of glucose by the cells, and modulates the activity of various signaling molecules and transcription factors.

Antidepressant Effect of Dimeric Dipeptide GSB-106, an Original Low-Molecular-Weight Mimetic of BDNF.

A large amount of clinical and experimental data suggest the involvement of neurotrophins, in particular the brain-derived neurotrophic factor (BDNF), in depression pathogenesis. However, the therapeutic use of BDNF is limited because of its instability in biological fluids, poor blood-brain barrier (BBB) permeability, and the presence of side effects. A low-molecular-weight mimetic GSB-106, which is a substituted dimeric dipeptide bis(N-monosuccinyl-L-seryl-L-lysine)hexamethylenediamide, was designed and synthesized based on the BDNF fourth loop structure at the V.

Urokinase induces matrix metalloproteinase-9/gelatinase B expression in THP-1 monocytes via ERK1/2 and cytosolic phospholipase A2 activation and eicosanoid production.

Objective: Urokinase-type plasminogen activator (uPA) regulates cell migration and invasion by pericellular proteolysis and signal transduction events. We characterized the mechanisms by which uPA regulates matrix metalloproteinase-9 (MMP9) function in THP-1 monocytes.

Methods And Results: In THP-1 monocytes, MMP9 production induced by urokinase was completely inhibited by the ERK1/2 inhibitor, PD98059, but not by the p38 mitogen-activated protein kinase inhibitor, SB202190.
