Wheat head blast (WHB), caused by the fungus Pyricularia oryzae pathotype Triticum (PoT), is a major disease affecting wheat in the Brazilian Cerrado region. This disease can significantly reduce grain yield because the environmental conditions in the tropical Cerrado biome favor PoT infection of wheat heads. This study aimed to evaluate the effect of the 2NS/AS translocation on WHB resistance and its impact on key yield compo...

Childhood trauma is associated with the development of psychiatric disorders in adulthood, including major depressive disorder (MDD). In preclinical research, animal models are widely used to investigate behavioral and neurobiological alterations related to depressive-like phenotypes, including anhedonia, anxiety-like behavior, and cognitive deficits. Several studies have shown that physical exercise is beneficial for MDD. How...

Background early-life challenges during the prenatal period can induce persistent neurological alterations. The immature innate immune system exhibits plasticity, and appropriately timed stimuli may shape immune responses into adulthood. Objective to investigate whether prenatal exposure to lipopolysaccharide (LPS) modulates brain alterations after sepsis in adult offspring of both sexes. Methods pregnant Wistar rats received...

Fipronil is a widely used agricultural insecticide associated with the contamination of apiculture products and honeybee mortality. This study evaluated the presence of fipronil in honey samples from conventional and agroecological apiaries in Paraná, Brazil, and its toxic effects on Africanized Apis mellifera bees. Honey from four conventional apiaries showed fipronil levels above the maximum residue limit (0.05 µg mL −1 ), w...
