COVID-19 vaccination shifts neutrophils toward a mixed activated and regulatory phenotype in patients with severe diseaseNARA Subscribed
Background Dysregulation of the innate immune response to SARS-CoV-2 has been linked to poor outcomes in COVID-19. Neutrophils are key players in this response, displaying distinct functional profiles associated with disease severity. This study investigates how neutrophil phenotypes, and their mediators are modulated in severe COVID-19 following vaccination. Methods and Results We conducted an observational case-control study...
The endocannabinoidome–microbiota axis in obesity: a potential link to colorectal cancer developmentNARA Subscribed
Colorectal cancer (CRC) is a multifactorial disease strongly influenced by genetic and environmental factors, as well as by immune and metabolic disorders such as obesity and gut dysbiosis. Recent evidence highlights the interplay between the endocannabinoidome (eCBome) and the gut microbiota as a central regulatory axis of intestinal homeostasis, metabolism, and immune responses. Although no studies have directly investigated...
Prebiotics and probiotics in animal nutrition: implications for food safety, sustainability, and circular production systemsNARA Subscribed
The pursuit of sustainable and efficient animal production systems has intensified global interest in microbiota-targeted nutritional strategies. This review synthesizes current research on prebiotics and probiotics, selectively utilized microbial substrates and beneficial live microorganisms, respectively, that confer health benefits, across major livestock and aquaculture sectors, including poultry, swine, ruminants, fish, a...
Biochar-driven shifts in the soil bacterial community structure of degraded semiarid soilsNARA Subscribed
Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...
Inhabiting the host: ectoparasites and Vector-Borne pathogens in Phyllostomidae bats within urban forest fragmentsNARA Subscribed
While bats are known to harbor various viruses and bacteria, their role as hosts for hemoparasites has not been extensively studied. This research investigated the presence of ectoparasites and vector-borne pathogens—including Anaplasmataceae agents, hemoplasmas, apicomplexans, and kinetoplastids—in 74 Phyllostomidae bats sampled from an urban forest fragment in southeastern Brazil. Overall, 31.1% of the bats were infested wit...
Organomineral fertilization with sewage sludge: heavy metal content in the soil and bioaccumulation in Urochloa brizanthaNARA Subscribed
The use of sewage sludge as biochar or compost in organomineral fertilizers has been investigated as an alternative to mineral fertilizers, as it can maintain crop yields, reduce environmental impacts, and improve soil quality. Therefore, this study aimed to evaluate the efficiency of organomineral fertilizers derived from sewage sludge and lignolytic compounds, formulated through different technologies, on the bioaccumulation...
Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120 sites using active search and litter sifting. Native vegetation cover was quantified...
