Quercetin Reduces the Susceptibility to Cardiac Reperfusion Arrhythmias in Ovariectomized Rats.

Cardiovascular diseases (CVDs) are the leading cause of death globally. Decrease in female sex hormones during menopause increases the risk of cardiovascular disease, mainly ischemic heart disease (IHD). Quercetin, a flavonoid, has beneficial properties in CVDs due to its antioxidant, anti-inflammatory, and anti-apoptotic effects.

Dealing with Childhood Externalizing Behavior: Protocol for a Feasibility RCT of the Being a Parent Program.

Concerning numbers of childhood behavior problems have been reported worldwide. Parenting interventions are considered one of the most effective early strategies to intervene with externalizing conduct. This protocol outlines a feasibility RCT that aims to implement a parenting intervention in Portugal and (a) test key feasibility parameters, (b) assess the fidelity and acceptability of the program, and (c) explore its effectiveness in childhood behavior problems, parenting skills, parental concern, and parental sense of competence.

Effect of Eight Months of Swimming on Bone Quality of Different Anatomical Regions: A Study on Wistar Rat Models.

Swimming is a popular sport with several health benefits, but its effects on bone quality are controversial possibly due to distinct effects on different anatomical regions. Our aim was to investigate the effect of 8-month swimming on bone growth, mass, geometry, trabecular microarchitecture and osteocyte density of the lumbar vertebrae, femur and tibia of male rats. Wistar rat models were assigned to either a swimming (n = 10; 2h/d, 5 d/week) or a physically active control group (n = 10) for 8 months, after which they were sacrificed and their lumbar vertebrae, femur and tibia assessed for bone mass, cortical geometry, trabecular microarchitecture and osteocyte density through µ-CT and histology.

Do you have enough space? Habitat selection of insectivorous cave-dwelling bats in fragmented landscapes of Eastern Amazon.

Individual movements of bats are triggered by their life requirements, limited by their recognition of the environment and risks of moving, and mediated by habitat selection. Mining adds fragmentation and heterogeneity to landscapes, with poorly understood consequences to the life activities of the bats. Cave dwelling bats spend most of their life cycles within caves, and as they constantly forage in external landscapes, their contribution in the input of organic matter to the caves is of paramount importance to the subterranean biodiversity.

Dermatological manifestations during Dengue, Chikungunya, and Zika infections.

Purpose Of Review: Arboviral infections caused by Dengue, Zika, and Chikungunya viruses continue to pose a significant global health threat, particularly in endemic regions. This review is timely because of the increasing prevalence of these infections, driven by factors such as urbanization and climate change. Dermatological manifestations of these viruses are crucial for early diagnosis, especially given the overlap in symptoms, which can complicate differential diagnosis.
