Toxicity of PAHs-enriched sediments on meiobenthic communities under ocean warming and CO-driven acidification scenarios.

This study aimed to assess the interactive effects of CO-driven acidification, temperature rise, and PAHs toxicity on meiobenthic communities. Laboratory microcosms were established in a full factorial experimental design, manipulating temperature (25 °C and 27 °C), pH (8.1 and 7.

Coinfection with Canine Distemper Virus and Yellow Fever Virus in a Neotropical Primate in Brazil.

We describe a natural coinfection with canine distemper virus (CDV) and yellow fever virus in a free-ranging neotropical primate of the genus , found dead in the northeastern region of Brazil. The laboratory diagnosis included histopathology, immunohistochemistry, rRT-PCR, and phylogenetic analyses. The CDV sequences from this primate in Brazil represent a divergent lineage in Rio Grande do Norte, closely related to genotypes EU1/South America 1 and South America 2.

Biomechanical and histological analyses of a multilayer stent in a swine model of suprarenal aortic aneurysm.

Objectives: To analyze and compare, in an animal model, the treatment of thoracoabdominal aneurysms with multilayer stents and its hemodynamic effects through the biomechanical and histological analysis of the aortic wall in contact with the stent.

Methods: Large White pigs were randomized into two groups: Stent (n=6) and Control (n=5, non-stent). All animals were subjected to the creation of a suprarenal aneurysm with a bovine pericardial patch.

Poultry Preslaughter Operations in Hot Environments: The Present Knowledge and the Next Steps Forward.

Poultry production faces significant challenges, including high feed prices, diseases, and thermal stress, which impact broiler welfare and productivity. Despite advances in cooling technologies and ventilation, preslaughter operations still lead to considerable losses. This review highlights the need for the improved management of thermal environments and animal logistics.
