Physical exercise alleviates oxidative stress in brown adipose tissue and causes changes in body composition and nutritional behavior in rats with polycystic ovary syndrome.

Aim: Polycystic Ovary Syndrome (PCOS) is a very common endocrine disorder in women. We investigate the effect of physical exercise on body composition, nutritional parameters, and oxidative stress in rats with PCOS.

Methods: Female rats were into three groups: Control, PCOS, and PCOS + Exercise.

Exercise and pyridostigmine prevents gastric emptying delay and increase blood pressure and cisplatin-induced baroreflex sensitivity in rats.

Cisplatin treatment induces an autonomic dysfunction and gastrointestinal and cardiovascular disorders. Physical exercise as well as pyridostigmine treatment induces improves in the autonomic nervous system. In the current study, we investigated the effect of physical exercise and pyridostigmine treatment on gastrointestinal and cardiovascular changes in cisplatin-treated rats.

L-Glutamine and Physical Exercise Prevent Intestinal Inflammation and Oxidative Stress Without Improving Gastric Dysmotility in Rats with Ulcerative Colitis.

The aim of this study was to evaluate the effects of glutamine supplementation or exercise on gastric emptying and intestinal inflammation in rats with ulcerative colitis (UC). Strength exercise consisted of jump training 4 × 10 repetitions/5 days a week/8 weeks with progressive overload. Endurance exercise consisted of swimming without overload for a period of 1 h a day/5 days a week/8 weeks.

Win 55,212-2, atenolol and subdiaphragmatic vagotomy prevent acceleration of gastric emptying induced by cachexia via Yoshida-AH-130 cells in rats.

The aim of this study was to investigate the effect of cachexia induced by AH-130 cells on gastrointestinal motility in rats. We evaluated food intake, body weight variation, cachexia index, gastric emptying and in vitro gastric responsiveness of control or cachexia rats. In addition, we evaluated the effect of pretreatment with atenolol (20 mg/kg, p.

Magnesium in Breast Cancer: What Is Its Influence on the Progression of This Disease?

Breast cancer is a disease of high mortality, characterized by the progressive accumulation of mutations that contribute to the uncontrolled development of breast tissue cells. Literature shows that disturbances in mineral homeostasis, such as magnesium, may interfere with tumor progression. The objective of this study is to provide updated information about magnesium's role in the pathogenesis of breast cancer.

Role of Magnesium in Oxidative Stress in Individuals with Obesity.

Adipose tissue is considered an endocrine organ that promotes excessive production of reactive oxygen species when in excess, thus contributing to lipid peroxidation. Magnesium deficiency contributes to the development of oxidative stress in obese individuals, as this mineral plays a role as an antioxidant, participates as a cofactor of several enzymes, maintains cell membrane stability and mitigates the effects of oxidative stress. The objective of this review is to bring together updated information on the participation of magnesium in the oxidative stress present in obesity.

The impact of gestational diabetes and hypothyroidism on the third-trimester ultrasound parameters and in adverse perinatal outcomes: a retrospective cohort study.

Objective: To assess the impact of gestational diabetes and hypothyroidism on the third-trimester ultrasound parameters and in adverse perinatal outcomes.

Methods: We performed a retrospective cohort study with 817 singleton pregnant women between 26w0d and 37w6d of gestation which were divided in four groups: 56 gestational diabetes mellitus (GDM), 63 hypothyroidism, 14 GDM + hypothyroidism, and 684 controls. The following ultrasound parameters were assessed: mean uterine artery pulsatility index (PI), umbilical artery PI, middle cerebral artery PI, single deepest pocket (SDP) and cerebroplacental ratio (CPR).
