Quercetin Supplementation Reduces Oxidative Stress in the Testes of Wistar Rats Fed a High-Fat Diet.

Problem: A high-fat diet (HFD) predisposes animals to glucose intolerance, dyslipidemia and testicular oxidative stress, and impairs sperm production in rats. Quercetin is a flavonoid with antioxidant, anti-inflammatory, and lipolytic actions and is a potential supplement to combat the oxidative stress caused by HFD and its harmful effects on reproduction. This study evaluated the effects of quercetin supplementation at doses of 10 and 20 mg/day on reproductive parameters and testicular oxidative stress in Wistar rats fed a diet rich in pork fat and fructose.

The oxygen reserve index (ORi) is a novel, non-invasive parameter that estimates arterial oxygen partial pressure (PaO) during hyperoxia when the fraction of inspired oxygen (FiO) is elevated. This study aimed to assess the utility of the ORi/FiO ratio as an index for quantifying F-shunt, serving as an estimate of venous admixture. Anesthetic records were reviewed from 44 dogs undergoing general anesthesia and requiring arterial catheterization.

Introduction: Athletes competing in weight-class sports often seek to gain an advantage by competing at lower weights. Athletes competing in weight-class sports often seek to gain an advantage by competing at lower weights. To achieve this, they aim to lose weight during the competition period, leading to various physiological and psychological changes.

Nutritional status during the developmental periods leads to predisposition to several diseases and comorbidities, highlighting metabolic and reproductive changes throughout adult life, and in the next generations. One of the experimental models used to induce undernutrition is litter size expansion, which decreases the availability of breast milk to pups and delays development. This work evaluated the effects of maternal undernutrition induced by litter size expansion, a maternal undernutrition preconception model, on the metabolic and reproductive alterations of the offspring.

Introduction: Non-nutritive sucking (NNS) is commonly employed to assist in the development of preterm infants facing feeding challenges. The effectiveness of NNS interventions on sucking performance (suction and expression/compression component of sucking) in this population has not yet to be systematically explored.
Aims: To review the literature on the effects of NNS on sucking performance in preterm infants.
