Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook ( Centropomus parallelus ) in the South Atlantic

ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicator...

Evaluating Rainfall Forecast Skill in Numerical Weather Prediction Models and the Effects of Bias Correction on the PCJ (Piracicaba-Capivari-Jundiaí) River Basins in Brazil

Precipitation forecasts from numerical weather prediction systems can contain systematic errors in both occurrence and magnitude, limiting their usefulness for hydrological applications. This study evaluated two operational precipitation forecasting systems against two observatio...

How common is alcohol use disorder in posttraumatic stress disorder? A systematic review, meta‐analysis, and moderator analysis

BACKGROUND AND OBJECTIVES: Comorbidity between posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) complicates care, yet reported prevalence varies widely across settings and methods. We estimated AUD prevalence among adults with PTSD and identified sources of var...

Individual and Combined Effects of Commercial Glyphosate and Dicamba-Based Herbicide Formulations on Cytotoxicity, Oxidative Stress and Cell Death on Human Intestinal Caco-2 Cells

Pesticide contamination of food and environmental matrices represents a potential risk to human health. This study investigated the toxicological effects of commercial glyphosate and dicamba-based herbicide formulations, individually and in combination, on human intestinal epithe...

Autoantibodies neutralizing type I interferons underlie a third of cases of Chikungunya virus encephalitis or myelitis

Abstract Chikungunya virus (CHIKV) infection is typically not life-threatening but may, in rare cases, affect the central nervous system (CNS). In three cohorts of confirmed CHIKV cases from Martinique (French overseas territory) and Brazil (patients aged 0–89 years, n = 245), 20...

LC-QTOF-MS Chemical Characterization, Cytotoxicity, and Antimicrobial Activity of Blue Geopropolis: An Emerging Type of Brazilian Propolis

Background/Objectives: This study characterized blue geopropolis from Melipona quadrifasciata quadrifasciata (southern Brazil) by comparing its chemical composition, cytotoxicity, antimicrobial activity, and coloration mechanisms directly against green and red Apis mellifera prop...
