Neotropical freshwater biodiversity is remarkable, mainly due to historical, biotic, and environmental processes. Landscape connectivity can promote or restrict species dispersal in fish metacommunities, thereby influencing the diversity and phylogenetic structure of communities. This study evaluated whether structural landscape variables of the Tramandaí River basin affect the phylogenetic diversity of the component communiti...

The physiological quality of seed potato tubers during storage is important for maintaining their subsequent performance. This study evaluated the effects of harvest timing and storage temperature on Asterix and Orchestra seed potato tubers produced in Rio Paranaíba, Brazil. Tubers were harvested on August 10 and September 15, 2024, stored at 1.5, 3.5, or 6.5 °C, and evaluated for up to 120 and 90 days, respectively. Sprouting...

Anthropogenic habitat transformation has led to population declines and increasing isolation of populations of many species, particularly top predators, where small and fragmented populations often experience limited dispersal and reduced genetic diversity. Jaguars ( Panthera onca ), for example, have lost half of their historical range and most populations outside the Amazon biome are small, isolated and highly threatened. He...

In modern sows, litter size often exceeds the number of functional teats. Therefore, many farms retain surplus piglets within the litter. The present study evaluated the effect of cross-fostering biological litters with up to two surplus piglets relative to functional teats, allowing piglet replacement until day three of lactation. Females were selected ( n = 201) at farrowing and evenly distributed among treatments: +0 (numbe...

Purpose To investigate the effects of 24 weeks of resistance training (RT) on pro- and active matrix metalloproteinases (MMPs) and their association with functional performance in end-stage kidney disease (ESKD) patients undergoing hemodialysis. Methods Forty-two ESKD patients (mean age: 65 ± 4 years; dry body mass: 71 ± 16 kg; body mass index: 25 ± 3 kg/m 2 ) were randomized into two groups: the control (CTL, n = 20) and RT g...

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...
