The objective of the present study was to evaluate the effects of the genetic merit for backfat thickness (GMB) and subcutaneous fat thickness (FT) on meat quality traits of Nellore and crossbred (½ Aberdeen Angus + ½ Nellore) steers. The animals were obtained by mating Nellore cows with Nellore or Aberdeen Angus bulls. Both paternal genetic groups were selected to provide positive (+, high GMB) or negative (-, low GMB) expect...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

The dynamics of moisture transport in the Amazon are key to the South American water cycle. Convection-permitting regional climate models (CPRCMs) offer a valuable tool to better understand these processes. This study evaluates integrated water vapor transport (IVT) and precipitation in the Amazon Basin using a CPRCM simulation during austral summer (DJF) and winter (JJA). Simulations at 4.5 km resolution cover most of South A...

Ischemic stroke is a leading cause of disability worldwide, with current therapies mainly focused on clot fibrinolysis rather than neuroprotection. Nestorone ® (NES), a highly selective progesterone receptor agonist, has shown neuroprotective potential in experimental stroke. However, NES exhibits poor water solubility and high hepatic first-pass metabolism, limiting its oral bioavailability, which motivated us to develop new...

Background Posttraumatic stress disorder (PTSD) is increasingly recognized as a sequela of subarachnoid hemorrhage (SAH); however, its prevalence and clinical correlates remain understudied. This study assessed the prevalence of PTSD symptoms and associated psychological symptoms among survivors of SAH. Methods A 6-month prospective analysis of 45 SAH survivors from the GASH trial (NCT03569540) was conducted. PTSD symptoms wer...

Records of tick parasitism in Brazilian birds result from specific community studies, in which similar parasitic rates are found among species phylogenetically close and with similar habitat use. However, to understand the tick–bird dynamics, it is necessary to consider the ecological aspects of the organisms and the environment. Over a year, during both dry and rainy periods, we captured three Thamnophilidae species with mist...
