Fungal Biodiversity From the Atlantic Forest With Bioactive Metabolites Against Cutaneous Leishmaniasis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Biodiversity offers a rich source of bioactive compounds for drug discovery. We isolated Aspergillus fumigatus from compost in the Atlantic Forest and found its extract active against Leishmania (Leishmania) amazonensis. Two crude extracts, I06 and I75, were selected for further study.

Superovulation with an anti-inhibin monoclonal antibody improves the reproductive performance of rat strains by increasing the pregnancy rate and the litter size

Scientific Reports
Rats are multiparous rodents that have been used extensively in research; however, the low reproductive performance of some rat strains hampers the broader use of rats as a biomedical model.

Lean ZSF1 rats in basic research on heart failure with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 1474-1478, April 2025.
Abstract Aims ZSF1 obese rats harbouring two mutant leptin receptor alleles (Leprcp and Leprfa) develop metabolic syndrome and heart failure with preserved ejection fraction (HFpEF), making them a widely used animal model in cardiometabolic research.

Inhalation of welding fumes reduced sperm counts and high fat diet reduced testosterone levels; differential effects in Sprague Dawley and Brown Norway rats

Particle and Fibre Toxicology, 2020
Background Previous studies have shown that inhalation of welding fumes may induce pulmonary and systemic inflammation and organ accumulation of metal, to which spermatogenesis and endocrine function may be sensitive.

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

Effects of Amphetamine on Striatal Dopamine Release, Open-Field Activity, and Play in Fischer 344 and Sprague–Dawley Rats

, 2015
Previous work from our laboratories has shown that juvenile Fischer 344 (F344) rats are less playful than other strains and also appear to be compromised in dopamine (DA) functioning.
