Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...

Resistance training in rodent models is widely used to investigate muscular and cardiovascular adaptations. Traditional models often attach loads to the tail. The present study aimed to develop and validate a resistance training model for rats using a pulley system combined with a load-bearing vest, allowing progressive overload without tail attachment. Spontaneously hypertensive rats were assigned to control (CTR, n = 4) or r...

Background Benign prostatic hyperplasia (BPH) is a highly prevalent condition among aging men and a major cause of lower urinary tract symptoms (LUTS). Although α1-adrenoceptor blockers and 5-alpha-reductase inhibitors remain the cornerstone of treatment, their long-term use is frequently limited by adverse effects and suboptimal symptom control. Growing experimental and clinical evidence suggests that chronic prostatic inflam...

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...

Soil microbiomes are critical for ecosystem functioning, yet the global influences of climate and agricultural practices on their diversity and structure remain incompletely characterized. Here we analyzed 1921 soil samples from 33 countries worldwide across diverse biomes to assess how climate gradients and agricultural inputs, including pesticides and fertilizers, shape prokaryotic and fungal communities. We found that micro...
