Chronic kidney disease is an increasing global public health concern, and the Developmental Origins of Health and Disease (DOHaD) concept proposes that adverse conditions during critical developmental windows predispose offspring to chronic disorders later in life. Maternal protein restriction (MPR), a well-established experimental model reflecting food insecurity, has been shown to impair nephrogenesis and promote long-term r...

Expanding integrative cytogenetic and molecular analyses is essential for understanding the evolutionary dynamics of chromosome number variation in fishes. This study presents the first cytogenetic characterization of Hypostomus sertanejo , an endemic species native to the semi-arid Jaguaribe River basin in Northeastern Brazil. Cytogenetic analysis revealed a diploid number of 2n = 52, which is the lowest documented for the ge...

Poisoning of companion animals resulting from exposure to analgesics intended for human use is a frequent and clinically relevant problem in veterinary practice, usually associated with administration without professional supervision. This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are u...

The aim of the present study was to evaluate the effects of dietary supplementation with the microalgae Nannochloropsis oculata and Phaeodactylum tricornutum , either separately or in combination, on growth performance, lipid profile, haematoimmunological parameters, and resistance to Edwardsiella tarda infection in Nile tilapia ( Oreochromis niloticus ). A total of 960 juvenile Nile tilapia (2.87 ± 0.68 g and 5.65 ± 0.16 cm)...

In the face of climate change, agricultural modelling combined with experimental research is essential for predicting yields in diverse climatic scenarios. This study calibrated, validated and applied the AquaCrop model for forage sorghum under future climate scenarios in a semi‐arid region between 2020 and 2022. Meteorological data, soil moisture, canopy cover and crop productivity were collected. Model performance was evalua...

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...

This study evaluated the effects of increasing inclusion levels of biological silage produced from tambaqui ( Colossoma macropomum ) by-products (BST) in diets of commercial hens at different ages. A completely randomized design in a 2 × 5 factorial arrangement was adopted, comprising two hen ages (23 and 83 weeks) and five BST inclusion levels (0, 1, 2, 3, and 4%), with four replicates of six birds per treatment. Moderate BST...
