Influence of a 1000 Times Weakened Magnetic Field on Embryogenesis and Ontogenesis of the Japanese Quail in Several Generations.

The paper presents experimental data on the influence of a 1000-fold weakening of the Earth's magnetic field on the embryonic and postembryonic development of the Japanese quail in three generations. It has been shown that the weakening of the earth's magnetic field by a factor of 1000 affects the formation of blood vessels in Japanese quail embryos, in particular, causing a decrease in angiogenesis in seven-day-old embryos of both the first generation (F) and the next two ones (F and F). Pathological and anatomical studies of embryos of different ages in three generations have revealed various pathologies associated with vascular system disorders, as well as disorders in the development of the beak and eyes.

Radioprotective role of cyanobacterial phycobilisomes.

Cyanobacteria are thought to be responsible for pioneering dioxygen production and the so-called "Great Oxygenation Event" that determined the formation of the ozone layer and the ionosphere restricting ionizing radiation levels reaching our planet, which increased biological diversity but also abolished the necessity of radioprotection. We speculated that ancient protection mechanisms could still be present in cyanobacteria and studied the effect of ionizing radiation and space flight during the Foton-M4 mission on Synechocystis sp. PCC6803.

[Secondary Structure of Aβ(1-16) Complexes with Zinc: A Study in the Gas Phase Using Deuterium/Hydrogen Exchange and Ultra-High-Resolution Mass Spectrometry].

Complexes of peptide fragment 1-16 of beta-amyloid with transition metals play an important role in the development of a broad class of neurodegenerative diseases, which determines the interest in investigating the structures of these complexes. In this work, we have applied the method of the deuterium/hydrogen exchange in combination with ultra-high-resolution mass spectrometry to study conformational changes in (1-16) beta-amyloid peptide induced by binding of zinc(II) atoms. The efficiency of the deuterium/hydrogen exchange depended on the number of zinc atoms bound to the peptide and on the temperature of the ionization source region.

[ACUTE HEPATIC LESION ASSOCIATED WITH MYOCARDIAL INFARCTION: CLINICAL SIGNIFICANCE AND MODERN DIAGNOSTICS].

This review of the literature is devoted to the problem of acute kidney injury (AKI) in patients with acute myocardial infarction (MI). We discuss the occurrence of AKI in patients with MI, mechanisms of its development and modern diagnostic methods. The article examines biomarkers of kidney injury that may be useful for early diagnostics of AKI.
