The ratio of reactive oxygen and nitrogen species determines the type of cell death that bacteria undergo.

Reactive oxygen and nitrogen species (RONS) are emerging as a novel antibacterial strategy to combat the alarming increase in antimicrobial resistance (AMR). RONS can inhibit bacterial growth through reactions with cellular molecules, compromising vital biological functions and leading to cell death. While their mechanisms of action have been studied, many remain unclear, especially in biologically relevant environments.

Surviving in the urban jungle: The role of foam nests as thermal insulator in Pleurodema borellii (anura: Leptodactylidae).

Urbanisation stands as a primary driver of biodiversity loss globally, reshaping natural landscapes and imposing novel environmental conditions upon organisms. This ecological novelty poses challenges, and species capable of thriving in urban environments are considered tolerant. Among vertebrates, anurans are the most susceptible to land-use changes, mainly due to their life history and morphological traits.

Effect of dietary protein on serum hepcidin and iron in adults with obesity and insulin resistance: A randomized single blind clinical trial.

Background And Aims: Both obesity and iron deficiency are public health problems. The association between the two problems could be explained by chronic low-grade inflammation in obesity, which could stimulate hepcidin expression and modify iron concentration that the consumption of high-protein diets could prevent. Thus, this study aimed to compare the effects of high-protein diets with a predominance of animal or vegetable protein on serum hepcidin and iron concentrations in adults with obesity.

Comparison of safety and efficacy of femoropopliteal arterial disease using different dose drug-coated balloons: Systematic review and meta-analysis.

Background: Endovascular therapy with balloon percutaneous angioplasty (PTA) in the femoro-popliteal segment is frequently performed, however, long-term favorable outcomes and patency remain challenging, with restenosis rates reaching 60% post-standard balloon angioplasty. Drug-coated balloons (DCBs) have shown promise in improving these outcomes; Paclitaxel, used in DCBs, inhibits hyperplasia and smooth muscle cell proliferation, reducing restenosis; however, the optimal dose of Paclitaxel remains unclear, with high-dose (HD-DCB [>3 mg/mm]) and low-dose (LD-DCB [<2.0 mg/mm]) options available.

Efficacy and safety of guselkumab in patients with active lupus nephritis: results from a Phase 2, randomized, placebo-controlled study.

Objective: Evaluate the efficacy and safety of guselkumab, an interleukin (IL)-23 inhibitor, in a Phase 2, multicentre, randomized, double-blind, placebo-controlled study of patients with active lupus nephritis (LN).

Methods: Adults (18-75 years) with active LN (Class III-IV proliferative nephritis [kidney biopsy] and urine protein-to-creatinine ratio [UPCR)] of ≥ 1 mg/mg despite standard-of-care therapy) were randomized (1:1; planned sample = 60) to receive intravenous infusions of guselkumab 400 mg or placebo at Weeks 0, 4, and 8, then subcutaneous injections (guselkumab 200 mg or placebo) at Week12 and every 4 weeks through Week48 in addition to their background therapy. The primary end point was achievement of ≥ 50% decrease in proteinuria from baseline at Week24.

Over 400 food resources from Brazil: evidence-based records of wild edible mushrooms.

Many species of mushroom-forming fungi have been harvested in the wild and used for food and medicine for thousands of years. In Brazil, the knowledge of the diversity of wild edible mushrooms remains scattered and poorly studied. Based on new samples, bibliographic records revision, and searches through the GenBank, we recorded 409 species of wild edible mushrooms in Brazil, of which 350 can be safely consumed and 59 are edible but with conditions.

Habitat loss and discontinuity as drivers of habitat fragmentation: The role of contamination and connectivity of habitats.

Habitat discontinuity of aquatic environments is a serious problem that might hamper the different activities performed by organisms. When combined with contamination, the consequences for the population's dynamics might be exacerbated, particularly regarding foraging activity. Therefore, the aim of this study was to evaluate the combined effects of habitat discontinuity and contamination on the foraging behavior by zebrafish (Danio rerio) and on their ability to explore heterogeneous landscapes.

Two-flap earlobe rotation for extensive mid-helix defect: a case report of a new modification to an existing technique.

Reconstructing ear defects in very elderly patients is challenging, but one-step procedures are beneficial due to reduced morbidity and fewer hospital visits while maintaining ear size, shape, and symmetry. In 2018, Jaber . introduced a 90° earlobe rotation technique to repair full-thickness auricular defects while preserving the earlobe.
