[Pharmacological correction of hypoxia in patients with severe carbon monoxide poisoning].

The article deals with the materials, which have been received in the process of the examination and treatment of 44 patients with acute severe methadone poisonings. It has been revealed, that gravity of these patients' condition depends on the intensity of hypoxia due to breath deficiency because of methadone. The development of hypoxia, in its turn, causes violations of antiradical protection system and intensification of processes of peroxide lipid oxidation. It has been registered that the including of reamberin into the complex program of the intensive therapy of acute severe methadone po

Anoxia tolerance of con-familial tiger beetle larvae is associated with differences in energy flow and anaerobiosis.

In this study, we compared survivorship, heat dissipation and biochemical features of anaerobiosis of two tiger beetle species (Coleoptera: Cicindelidae) exposed to anoxia. One species commonly experiences environmental immersion from rainfall and snowmelt (Cicindela togata), and the habitat of the other (Amblycheila cylindriformis) is not prone to flooding. The ancestral genus, A. cylindriformis, survives anoxia for only 2 days at 25 degrees C. In response to anoxia, these larvae immediately lose locomotory abilities, tissue concentrations of ATP fall precipitously within 12 h, and significan

Loss of APOBEC1 disrupts RNA editing homeostasis and accelerates prion disease progression.

BACKGROUND: RNA editing is an epitranscriptomic mechanism that shapes transcriptome diversity and fine-tunes neuronal function. While adenosine-to-inosine (A-to-I) editing by ADAR enzymes has been extensively studied in neurodegenerative disorders, the role of cytidine-to-uridine (C-to-U) editing catalyzed by APOBEC1 remains largely unexplored. METHODS: We investigated the impact of APOBEC1 on RNA editing homeostasis and prion disease progression using complementary in vitro and in vivo models. Global RNA editing and gene expression profiles were established in non-infected N2A and prion-infe…
