Health in the Legal Amazon: an analysis of morbidity and mortality indicators between 2010 e 2021.

We carried out the health situation analysis in the Legal Amazon through morbidity and mortality indicators and the comparison between intra and inter-state federation of the region and Brazil. Analysis of the health situation, trends, and identification of clusters in the Brazilian Amazon, for the period from 2010 to 2021, using secondary data available in official health information systems. Circulatory diseases were the main cause of death, representing 23% of deaths.

O-GlcNAcylation regulates tyrosine hydroxylase serine 40 phosphorylation and L-DOPA levels.

O-GlcNAcylation is a post-translational modification characterized by the covalent attachment of a single moiety of GlcNAc on serine/threonine residues in proteins. Tyrosine hydroxylase (TH), the rate-limiting step enzyme in the catecholamine synthesis pathway and responsible for production of the dopamine precursor, L-DOPA, has its activity regulated by phosphorylation. Here, we show an inverse feedback mechanism between O-GlcNAcylation and phosphorylation of TH at serine 40 (TH pSer40).

Comparative Analysis of the Enzymatic, Coagulant, and Neuromuscular Activities of Two Variants of Venom and Antivenom Efficacy.

We compared the enzymatic, coagulant, and neuromuscular activities of two variants (yellow-CDRy and white-CDRw) of venom with a sample of (CDT) venom and examined their neutralization by antivenom against CDT venom. The venoms were screened for enzymatic and coagulant activities using standard assays, and electrophoretic profiles were compared by SDS-PAGE. Neutralization was assessed by preincubating venoms with crotalic antivenom and assaying the residual activity.
