The effect of a warmed enema during ovum pick-up on subsequent oocyte maturation in Southern white rhinoceros .

Background: Rhinoceros are currently one of the most threatened mammal species globally. Slow population growth, increased poaching and habitat destruction have led to increased conservation efforts for each species. Assisted reproductive technologies (ART) have been implemented in an attempt to aid reproductive outputs for the conservation of these endangered species.

Influence of sleep on motor skill acquisition in children: a systematic review.

Effects of sleep on procedural (implicit) memory consolidation in children remain controversial. The aim of this systematic review was to synthesise the evidence on the influence of sleep on motor skills acquisition in children. Four electronic databases were searched: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Excerpta Medica Database (Embase), and Biblioteca Virtual em Saúde (BVS).

The double burden of malnutrition and environmental enteric dysfunction as potential factors affecting gut-derived melatonin in children under adverse environments.

Poor environmental conditions combined with continuous unhealthy and unsafe diets may substantially increase the risk of a vicious cycle of enteric infections (EED-environmental enteric dysfunction) and malnutrition (DBM-double burden of malnutrition) in children. Gut melatonin, mainly produced by the intestinal microbiota, can modulate the composition, variety, and dynamics of the microbiota itself and may affect and be affected by intestinal microbiota alterations due to DBM and EED.

Influence of angiotensin receptor and converting enzyme blockers therapy in the respiratory outcome of COVID-19 hospitalized patients.

Objectives: COVID-19, caused by SARS-CoV-2, has spread around the world since 2019. In severe cases, COVID-19 can lead to hospitalization and death. Systemic arterial hypertension and other comorbidities are associated with serious COVID-19 infection.

Melatonin supplementation enhances pulmonary rehabilitation outcomes in COPD: a randomized, double-blind, placebo-controlled study.

Melatonin (MLT), the main product of the pineal gland, is involved in muscle tissue repair and regeneration, besides several other important physiologic functions. In COPD, MLT administration can improve lung oxidative stress and sleep quality, but its potential effects on the outcomes of pulmonary rehabilitation (PR) have not been previously investigated. A randomized controlled trial was undertaken to test the hypothesis that a combined approach of rehabilitative exercise training and MLT supplementation could maximize functional performance, health status and quality of life in patients with COPD.
