The use of babassu agro-industrial residues in animal feed, in addition to being an economic option of great importance in reducing the environmental impact in regions of the Brazilian Cerrado, provides the production of good quality foods of animal origin due to its nutritional characteristics. However, information related to the nutritional components of babassu by-industrial residues has not yet been sufficiently explored. The aim of this study was to evaluate the nutritional potential of some by-products from the babassu production chain through chemical composition and in situ degradability analyses.

Article Synopsis
  • Glyphosate formulations have been linked to neurotoxicity, causing oxidative stress and mitochondrial dysfunction, but how they affect astrocytes is still uncertain.
  • A study found that 24-hour exposure to glyphosate reduced cell viability, mitochondrial enzyme activity, and mitochondrial mass in rat astrocyte cells while increasing non-protein thiol levels and autophagy-related proteins.
  • The results suggest that glyphosate may target mitochondria and creatine kinase, with increased autophagy and non-protein thiols possibly acting as protective responses against oxidative damage, but further research is needed to understand these mechanisms better.

Complexes [In(2Ac4oClPh)Cl(MeOH)] (1), [In(2Ac4pFPh)Cl(MeOH)] (2), [In(2Ac4pClPh)Cl(MeOH)] (3) and [In(2Ac4pIPh)Cl(MeOH)] (4) were obtained with N(4)-ortho-chlorophenyl-2-acetylpyridine thiosemicarbazone (H2Ac4oClPh), N(4)-para-fluorophenyl-2-acetylpyridine thiosemicarbazone (H2Ac4pFPh), N(4)-para-chlorophenyl-2-acetylpyridine thiosemicarbazone (H2Ac4pClPh) and N(4)-para-iodophenyl-2-acetylpyridine thiosemicarbazone (H2Ac4pIPh). Theoretical studies suggested that the coordinated methanol molecule can be easily replaced by DMSO used in the preparation of stock solutions, with the formation of [In(L)Cl(DMSO)] (HL = thiosemicarbazonate ligand), and that the replacement of DMSO by water is unfavorable. However, for all complexes the displacement of one or two chloride ligands by water in aqueous solution is extremely favorable.

The azoles are the class of medications most commonly used to fight infections caused by Candida sp. Typically, resistance can be attributed to mutations in ERG11 gene (CYP51) which encodes the cytochrome P450 14α-demethylase, the primary target for the activity of azoles. The objective of this study was to identify mutations in the coding region of theERG11 gene in clinical isolates of Candida species known to be resistant to azoles.

The Atlantic Rain Forest is one of the most important Brazilian biomes and a hotspot for biodiversity that is characterized by its high level of endemism, where new species are still being described. Luehea divaricata (Malvaceae) is commonly found in riparian forests areas of the Atlantic forest. Because of the importance of this species in reforestation programs, we used nine pairs of microsatellite loci to study the genetic variability of this species along its distribution area and verify if fragmentation is compromising the survival of these populations.
