Background The Passiflora genus presents a representative variability of passion fruit species with food, pharmacological and ornamental potential. To understand this genetic variability, it is essential that genetic resources are well characterized for future use in breeding and conservation programs. The aim of this study was to investigate for the first time the diversity genetic and structure population of 88 Passiflora ge...

The anesthetic management of female dogs with mammary neoplasia, usually classified as ASA II and undergoing invasive procedures such as mastectomy and ovariohysterectomy, requires effective sedation and anesthetic stability due to the increased anesthetic risk associated with advanced age and underlying disease. In this context, this study aimed to evaluate the sedative effects and reduction in anesthetic requirements of a fu...

Multiform glioblastoma (GBM) is the most aggressive primary brain tumor, associated with high heterogeneity, treatment resistance, and poor survival. Temozolomide (TMZ), although the main chemotherapeutic agent used, shows limited efficacy due to low solubility, chemical instability, and acquired resistance. In this context, nanostructured systems can enhance their antitumor efficacy. This study aimed to develop and characteri...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia that may impair testicular function, including spermatogenesis and steroidogenesis. Creatine, an endogenously synthesized nitrogenous compound and one of the main reservoirs in the testes, is widely used, particularly among men. However, evidence regarding its effects on male reproductive health, especially under DM, remains limite...

Aim Several lines of evidence have noted that open vegetation biomes in the Neotropics are younger than moist forests, leading us to question which historical processes shaped the current species distribution patterns in these new biome formations. Here we investigate the temporal patterns of speciation and colonisation from surrounding biomes (Amazonia, Atlantic Forest and Cerrado) in the Caatinga historical assembly of squam...
