Effects of time-restricted feeding in weight loss, metabolic syndrome and cardiovascular risk in obese women.

Background: The increasing prevalence of overweight and obesity among the worldwide population has been associated with a range of adverse health consequences such as Type 2 diabetes and cardiovascular diseases. The metabolic syndrome (MetS) is a cluster of cardiometabolic abnormalities that occur more commonly in overweight individuals. Time-restricted feeding (TRF) is a dietary approach used for weight loss and overall health.

Overheating or overcooling: heat transfer in the spot to fight against the pandemic obesity.

The prevalence of obesity has nearly doubled worldwide over the past three and a half decades, reaching pandemic status. Obesity is associated with decreased life expectancy and with an increased risk of metabolic, cardiovascular, nervous system diseases. Hence, understanding the mechanisms involved in the onset and development of obesity is mandatory to promote planned health actions to revert this scenario.

ADA activity is decreased in lymphocytes from patients with advanced stage of lung cancer.

Cigarette smoking is directly associated with lung cancer. Non-small cell lung carcinoma (NSCLC) represents approximately 80% from all types of lung cancer. This latter is hard to diagnose and to treat due to the lack of symptoms in early stages of the disease.

G protein-coupled receptor kinase 2 regulates mitochondrial bioenergetics and impairs myostatin-mediated autophagy in muscle cells.

G protein-coupled receptor kinase 2 (GRK2) is an important protein involved in β-adrenergic receptor desensitization. In addition, studies have shown GRK2 can modulate different metabolic processes in the cell. For instance, GRK2 has been recently shown to promote mitochondrial biogenesis and increase ATP production.

Physical exercise prevents memory impairment in an animal model of hypertension through modulation of CD39 and CD73 activities and A2A receptor expression.

Unlabelled: : Background: Central nervous system function has been emerging as an approach to understand hypertension-mediated memory dysfunction, and chronic exercise is able to modulate the purinergic system.

Method: Herein, we investigated the effect of chronic swimming training on the purinergic system in cortex and hippocampus of L-NAME-induced hypertensive rats. Male Wistar rats were divided into four groups: Control, Exercise, L-NAME and Exercise L-NAME.

High-intensity intermittent exercise increases adenosine hydrolysis in platelets and lymphocytes and promotes platelet aggregation in futsal athletes.

Acute bouts of high-intensity intermittent exercise (HIIE) or sports are associated with changes in lymphocytes and platelet functions and we hypothesized that the purinergic system is involved with these alterations. We investigated the activity of ectonucleotidases in platelets and lymphocytes as well as the platelet aggregation of futsal players in response to an acute protocol of HIIE. Thus, 19 male semi-professional futsal players were submitted to 40 min of HIIE on a treadmill.

Acute intermittent hypoxia in rats activates muscle proteolytic pathways through a gluccorticoid-dependent mechanism.

Although it is well known that chronic hypoxia induces muscle wasting, the effects of intermittent hypoxia on skeletal muscle protein metabolism remain unclear. We hypothesized that acute intermittent hypoxia (AIH), a challenge that activates the hypothalamic-pituitary-adrenal axis, would alter muscle protein homeostasis through a glucocorticoid-dependent mechanism. Three-week-old rats were submitted to adrenalectomy (ADX) and exposed to 8 h of AIH (6% O for 40 s at 9-min intervals).
