Bacteremia is a major health problem that affects millions of people worldwide. E. coli is one of the main pathogens associated with bacteremia and its resistance to the antimicrobial drugs, including β-lactams, has significantly increased in recent years. In view of the above, our objective was to determine the antimicrobial resistance profile of 60 E. coli isolates obtained from patients with bacteremia, as well as to charac...

Total plasma N -glycans alter in disease states, with few studies focused on COVID-19. A discovery cohort of 310 COVID-19 patients, replicated with 97 COVID-19 patients and tested with 100 COVID-19 patients, was used to unearth the N -glycans capable of distinguishing infection, as well as prognosis of intensive care unit (ICU) admission and mortality. All significant bisected glycans were decreased in patients compared to con...

This study aimed to evaluate the exposure of Chelonia mydas (green turtles) inhabiting the south coast of Pernambuco, Northeast Brazil, to essential and toxic elements. Concentrations of Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn were determined in shell, muscle, liver, and kidney samples from 43 individuals using ICP-OES. Element concentrations varied according to tissue type. Specifically, the average concentrations of A...

Objective To develop an endoscope reprocessing system using ozonated water jets. Methods The system features a jet head with concentric orifices that moves vertically to disinfect the external surface of the endoscope. Simultaneously, ozonated water is injected into the internal channel to ensure complete disinfection. Endoscopes were experimentally contaminated with Staphylococcus aureus and Escherichia coli . Quantitative an...

6-Cyanodopamine (6-CYD) is a recently identified endogenous catecholamine that exerts positive chronotropic and inotropic actions, but its occurrence in vascular tissue and effects on vascular reactivity are unknown. In endothelium-intact and endothelium-denuded rabbit isolated aortic rings, we investigated the basal release of 6-CYD and its effects on aortic smooth muscle reactivity. 6-Cyanodopamine release was quantified by...

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...

The 2024 catastrophic floods that devastated the southern Brazilian state of Rio Grande do Sul also affected the coastal environment of the world’s largest choked lagoon, the Patos Lagoon (PL). Given its size, satellite imagery presents an incomparable advantage to evaluate the effects of the floodwaters entering this ecosystem. To obtain a general overview of the event in the lagoonal water body, this research utilized Sentin...

Atlantic bluefin tuna (ABFT) is an ecologically and economically valuable species. As global warming drives marine species toward cooler or deeper waters, ABFT distributions are expected to shift, potentially disrupting predator–prey dynamics and fisheries interactions. This study models future habitat suitability for ABFT, its primary prey (as a proxy for food availability), and the drifting longline fishery that targets adul...

Cynara cardunculus inflorescence plays a significant role in cheese manufacturing and human consumption due to the milk-clotting capacity and the production of edible immature capitula. Consequently, it is crucial to understand the complex cellular and molecular processes involved in the development of cardoon flowers. The current study used western wild cardoon in two developmental stages, vegetative and reproductive, to unde...
