The objective of this study was to perform genomic, phylogenomic, and phenotypic characterization of bacterial isolates from a captive Cacatua alba to investigate their antimicrobial resistance profiles, virulence-associated genes, and genomic relationships with publicly available strains. Bacterial isolates obtained from the lungs and encephalon were identified as Escherichia coli (AV037), Enterobacter hormaechei (AV038), and...

Rhodococcus equi is an important bacterium that affects foals up to six months of age, especially those that are immunocompromised. The main manifestation is pyogranulomatous pneumonia; nevertheless, extrapulmonary lesions have not only been reported, but are not uncommon, including arthritis and osteomyelitis. Despite the widespread occurrence of rhodococcosis, the macro- and microscopic lesions in the musculoskeletal system...

This pilot study evaluated the short- and mid-term outcomes of intra-articular allogeneic canine adipose-derived stem cell (ADSC) enriched secretome in dogs undergoing tibial plateau levelling osteotomy (TPLO), focusing on postsurgical recovery and osteoarthritis (OA) progression. Twenty client-owned dogs were randomly assigned ( n = 10 per group) to a control group (CG), receiving placebo, or a treated group (ADSC-Se), receiv...

Cetaceans are sentinels of marine ecosystem health and are increasingly exposed to protozoal pathogens. This study investigated the occurrence and molecular identity of Sarcocystidae protozoa in 159 stranded cetaceans representing 21 species along the Brazilian coast. Molecular analysis based on PCR amplification and sequencing of the sarcocystid internal transcribed spacer 1 (ITS1) region revealed infections in 14 individuals...

Antarctica’s ice-free areas are mainly colonized by cryptogamic communities, which are known to be sensitive indicators of environmental change. Despite numerous monitoring-related studies, published research on medium-term cryptogam cover changes is limited. With this study, we aimed to investigate compositional and structural changes in cryptogamic communities over a decade near the Polish Arctowski Antarctic Station. Here,...

Organotellurium (OTe) compounds have pharmacological properties, including leishmanicidal, antimalarial, and antifungal activities. Herein, we assessed cytotoxicity effects of OTe RF07 in a panel of tumor cell lines, as well as its oxidative, toxicity, and hemolytic actions. The toxicity was evaluated on Allium cepa and Artemia salina larvae. Cell viability was also assessed by resazurin in murine cells (Sarcoma 180), human ce...

Euterpe edulis Martius (juçara palm) is an endangered species of high ecological and economic importance. Its propagation via reproduction is limited by the recalcitrance of its seeds, which hinders conservation and genetic improvement. Somatic embryogenesis represents an efficient alternative for large-scale clonal propagation and conservation. The present study evaluated the effect of abscisic acid (ABA) on histodifferentiat...

Euterpe edulis is of ecological and economic relevance and is currently threatened with extinction. Its vulnerability to extinction, combined with the recalcitrant nature of its seeds, justifies the search for alternative reproduction techniques. Somatic embryogenesis is an alternative propagation method that is subdivided into distinct phases. Maturation is a crucial phase in the process for the successful regeneration of som...

Mineral resource classification, based on confidence levels associated with tonnages and grades, is essential for public disclosure and for assessing deposit maturity and related risks. Although geometric classification methods are transparent and straightforward, they do not explicitly account for local variations in uncertainty. In contrast, geostatistical approaches focus primarily on the quality of grade estimation. The sc...

This study evaluates bioremediation using effective microorganisms (EM) to improve quality in the eutrophic Maricá Lagoon (RJ, Brazil). The intervention, implemented in late 2021, consisted of the regular application of EM in one of the lagoon’s main fluvial contributors: the Mumbuca-Ubatiba drainage basin. To evaluate bioremediation, physicochemical and biogeochemical variables were monitored in the water column and sediments...

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...

Euterpe edulis Martius (Arecaceae) is a native species of the Atlantic Forest hotspot with ecological and economic relevance. Its fruits contribute to biodiversity maintenance by feeding birds and mammals and are valued for their antioxidant properties and applications in the food and cosmetic industries. However, habitat loss and propagation constraints have contributed to the threatened status of this species, reinforcing th...
