Emotional words evoke region- and valence-specific patterns of concurrent neuromodulator release in human thalamus and cortex.

Words represent a uniquely human information channel-humans use words to express thoughts and feelings and to assign emotional valence to experience. Work from model organisms suggests that valence assignments are carried out in part by the neuromodulators dopamine, serotonin, and norepinephrine. Here, we ask whether valence signaling by these neuromodulators extends to word semantics in humans by measuring sub-second neuromodulator dynamics in the thalamus (N = 13) and anterior cingulate cortex (N = 6) of individuals evaluating positive, negative, and neutrally valenced words.

Safety and efficacy of three alternative regimens against relapsing Plasmodium vivax malaria in glucose 6-phosphate dehydrogenase deficient patients in the Brazilian Amazon (ALTPRIM).

Background: Daily primaquine-induced hemolysis is a common cause of complications during Plasmodium vivax malaria treatment in individuals with glucose 6-phosphate dehydrogenase deficiency (G6PDd). Alternative regimens balancing safety and efficacy are needed.

Methods: G6PDd participants with P.

Native and Non-Native Soil and Endophytic spp. from Semi-Arid Sisal Fields of Brazil Are Potential Biocontrol Agents for Sisal Bole Rot Disease.

Sisal () bole rot caused by is the main phytosanitary problem affecting sisal in the Brazilian semi-arid region. The aim of this study was to evaluate spp. as biocontrol agents for sisal bole rot.

High Power Short Duration Atrial Fibrillation Ablation: Long-Term Predictors of Success and Recurrence - A Multivariate Analysis.

Background: Point-by-point ablation with a high-power short-duration (HPSD) technique in atrial fibrillation (AF) ablation is used worldwide. Little data is available with the HPSD and dragging technique (DT).

Objective: To perform a multivariate analysis of clinical and procedural predictors of success and recurrence in HPSD with DT.

Unraveling the Nanomechanical and Vibrational Properties of the Mayaro Virus.

Mayaro virus (MAYV) is an emerging mosquito-borne viral pathogen whose infection results in arthritogenic disease. Despite ongoing research efforts, MAYV biology is largely unknown. Physical virology can assess MAYV nanoparticle metastability, assembly/disassembly, and polymorphism, allowing us to understand virion architecture and dynamics.
