Genetic ancestry proportion influences risk of adverse events from tuberculosis treatment in BrazilNARA Subscribed
Tuberculosis (TB) treatment is highly effective, but response to therapy varies by geography and population subgroups. We assessed differences in TB treatment response in a representative and heterogeneous Brazilian population. We estimated genetic ancestry according to major genetic ancestry groups (African, European, and Amerindian) in the Regional Prospective Observational Research in Tuberculosis (RePORT)-Brazil cohort usi...
Streptomyces amazonensis sp. nov. isolated from Madeira river sediments with genomic potential for secondary metabolite productionNARA Subscribed
The genus Streptomyces is recognized as a source of secondary metabolites (SMs) with applications in medicine, industry, and agriculture. This study presents the description and characterization of a new Streptomyces species, isolated from sediments of the Madeira River in the Brazilian Amazon. Four strains (CPAA MAD 27, CPAA MAD 39, CPAA MAD 42, and CPAA MAD 51) were obtained from sampling sites distributed along the river. T...
Species of Micropleura Linstow, 1906 (Dracunculoidea: Nematoda) are common parasites of crocodilians worldwide. Studies related to this genus remain scarce, particularly regarding genetic characterizations, due to the difficulty in obtaining the parasite specimens. Although the morphology of M . vazi Travassos, 1933, a parasite of Caiman spp. in the Neotropics, has been previously evaluated, some morphological inconsistencies...
Population decline of a leaf frog coincident with recurrent ranavirosis outbreaks in the Atlantic ForestNARA Subscribed
Amphibian populations are increasingly threatened by emerging pathogens, yet robust evidence linking disease outbreaks with population-level impacts remains scarce in the Neotropics. We investigated a mortality event affecting endemic treefrogs in the Brazilian Atlantic Forest by integrating field observations, molecular characterisation, histopathology, and long-term monitoring. Ranavirosis infection was the confirmed primary...
Solvent-dependent Sensitization and Photophysical Behavior of IrIII-EuIII Bimetallic ComplexesNARA Subscribed
The photophysical properties of a heterobimetallic Ir III –Eu III complex were investigated in solvents with different polarity, coordinating ability, and vibrational characteristics to elucidate the factors governing Eu III sensitization. Steady-state and time-resolved luminescence measurements revealed that the solvent profoundly influences both the donor-to-acceptor energy-transfer process and the europium-centered emission...
