Insilico molecular characterization of a cyanobacterial lytic polysaccharide monooxygenase.

Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that catalyze the oxidative cleavage of β(1-4) glycosidic bonds and have attracted considerable attention because of their potential for enhancing efficiency in degrading recalcitrant polymeric substrates, in synergism with hydrolytic enzymes. Fungal-derived LPMOs are the most prevalent type, while other taxonomic groups have been described as potential alternative sources of these enzymes. In the present study, we aimed to identify and characterize in silico a LPMO of cyanobacterial origin with putative functions in chitin depolymerization.

First molecular detection of in a domestic cat () from an urban area in eastern Amazon.

Background: Domestic cats have been implicated as accidental hosts of sp. However, in recent years, the recurrent description of new cases in endemic and nonendemic areas draw attention to the potential epidemiological role of cats as reservoir hosts. Although dogs are considered urban reservoirs, cats could act as a secondary natural reservoirs in these areas.

Incomplete myelopathy and human T cell lymphotropic virus type-1 (HTLV-1).

This was a cross-sectional prospective study. We performed a multivariate statistical analysis of the neurological signs and symptoms of patients infected with human T cell lymphotropic virus type 1 (HTLV-1) in an attempt to separate them into distinct groups and identify clinical-neurological manifestations that could differentiate the various profiles. The study was performed in the city of Belém (state of Pará), located in the Amazon region of Brazil, from 2014 to 2016.
