The teaching and learning of zoology and comparative anatomy face several challenges, including the identification of anatomical structures across different species, understanding evolutionary relationships, and promoting science communication and public engagement. In addition, the fragility of formalin-fixed specimens subjected to repeated handling limits their long-term use in practical classes. Plastination has emerged as...

Objective To evaluate whether patients with RLS have increased odds of ED compared with non-RLS controls. Methods We conducted a systematic review and meta-analysis analyzing the odds of ED in patients with RLS. We included studies that: (i) evaluated adults with a diagnosis of RLS established by the pre-established criteria; (ii) included a control group without RLS; and (iii) evaluated outcomes related to the odds of ED in p...

The dengue virus (DENV) belongs to the Flaviviridae family and is responsible for a febrile arbovirus disease of global relevance. In Brazil, there has been endemic circulation of the four viral serotypes since the last century, with DENV-3 being frequently associated with more severe clinical conditions and major epidemics. This study aimed to perform the motif characterization of DENV-3 strains circulating in Brazil and its...

The presence of palms on earth mounds may increase community phylogenetic diversity (PD) by promoting facilitation and acting as natural perches that enhance species recruitment. We investigated whether palm presence and mound size affect the phylogenetic diversity (alpha and beta) and structure of woody vegetation. We selected 42 earth mounds in an ecotone between the Cerrado and Caatinga biomes: 15 with Copernicia prunifera...

Carcharhinus galapagensis and Carcharhinus obscurus are challenging species to distinguish based on their physical characteristics, particularly after processing, which can hinder species-level monitoring in fisheries and conservation programs. In this study, we utilized diagnostic single nucleotide polymorphisms (SNPs) to identify 17 shark specimens collected from the Saint Peter and Saint Paul Archipelago in Brazil, a remote...
