Nanoparticles of nucleotide-free analogue of vitamin B formed in protein nanocarriers and their neuroprotective activity in vivo.

Recently, we have described the first supermolecular nanoentities of vitamin B derivative, viz. monocyano form of heptabutyl cobyrinate, unique nanoparticles with strong noncovalent intermolecular interactions, emerging optical and catalytic properties. Their nearest analogue, heptamethyl cobyrinate (ACCby), exhibits bioactivity.

[A systematic analysis of neurobiological roles of lithium].

Lithium salts have been the mainstay of treatment for bipolar disorder for more than 50 years, since the FDA approved the treatment in 1970. Molecular mechanisms of lithium's action include inhibition of glycogen synthase kinase 3 beta and inositol monophosphatase, resulting in induction of brain-derived neurotrophic factor, antiapoptotic proteins, deprivation of calcium-induced apoptosis. Recent findings suggest autophagy regulation as a possible mechanism of lithium neuroprotective action.

Rapid quasi-periodic oscillations in the relativistic jet of BL Lacertae.

Blazars are active galactic nuclei (AGN) with relativistic jets whose non-thermal radiation is extremely variable on various timescales. This variability seems mostly random, although some quasi-periodic oscillations (QPOs), implying systematic processes, have been reported in blazars and other AGN. QPOs with timescales of days or hours are especially rare in AGN and their nature is highly debated, explained by emitting plasma moving helically inside the jet, plasma instabilities or orbital motion in an accretion disc.

[Molecular and clinical aspects of the effect of cytidyndiphosphocholine on cognitive functions].

Objective: Systematization of the array of publications on cytidyldiphosphocholine (CDP-choline).

Material And Methods: Systematic computer analysis of all currently available publications on CDP-choline (1750 publications in PUBMED) using the topological theory of big data analysis.

Results: CDP-choline is essential for acetylcholine biosynthesis, phospholipid metabolism, and DNA methylation.

Does Protein Glycation Impact on the Drought-Related Changes in Metabolism and Nutritional Properties of Mature Pea ( L.) Seeds?

Protein glycation is usually referred to as an array of non-enzymatic post-translational modifications formed by reducing sugars and carbonyl products of their degradation. The resulting advanced glycation end products (AGEs) represent a heterogeneous group of covalent adducts, known for their pro-inflammatory effects in mammals, and impacting on pathogenesis of metabolic diseases and ageing. In plants, AGEs are the markers of tissue ageing and response to environmental stressors, the most prominent of which is drought.
