Inflammatory bowel disease (IBD) induces immunological and autonomic imbalances. Exercise is a beneficial strategy for controlling IBD symptoms. We investigated the role of exercise on gastrointestinal (GI) motility changes parameters in rats with ileitis. Rats were divided into control, ileitis, exercise+ileitis groups. Ileitis was induced by TNBS (40 mM, intraileally). The swimming (1 h/day/4 weeks, 5%/bw). assessed eating behaviour oxidative stress. Body composition bioimpedance....

Changes in dietary habits including increased intake of refined sugars and fats decreased fiber have been suggested as potential risk factors for the development inflammatory bowel diseases (IBD). Bioelectrical impedance analysis-derived phase angle (PhA) has gaining attention clinical evaluation nutritional status. In this study, we first time investigated relationship PhA ultra-processed food with oxidative stress, body composition biochemical parameters adult patients IBD.Body were...

The purinergic system participates in the control of blood pressure. Hypertension promotes occurrence gastrointestinal disorders such as intestinal inflammation and gastric emptying delay. This study aimed i) to investigate participation P2X7 receptor blocker Brilliant Blue G (BBG) on solids changes oxidative stress fundus, duodenum, colon spontaneously hypertensive rats (SHR) ii) putative relationship this effect with renin-angiotensin system. Rats were divided into five groups: Control,...

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 rats with PCOS.Female were into three groups: Control, PCOS, PCOS + Exercise. was induced by letrozole (1 mg/kg via p.o.) for 21 days consecutively. Physical swimming, consecutive days, 1 h/day 5 % load. In all groups, we assessed murinometric thermography, brown adipose tissue (BAT) peri-ovarian...

Patients undergoing chemotherapy with cisplatin commonly present gastrointestinal effects such as constipation and gastric emptying (GE) delay. Both the purinergic system physical exercise modulate (GI) tract. In current study, we investigated role of ATP, exercise, P2X7 receptor blocking on GE delay induced by in rats. Male rats were divided into following groups: control (C), (Cis), (Ex), Brilliant Blue G (BBG), Cis+Ex, Cis+ATP, Cis+BBG, Cis+Ex+BBG, Cis+Ex+BBG+ATP, Cis+ATP+BBG. was...

Background: In addition to the cardiovascular and renal systems, gastrointestinal tract also contains angiotensin ATR 1a , 1b 2 . We previously observed that 2Kidney-1Clip hypertension model elicits physical exercise dysmotility, which is prevented by renin-angiotensin system blockers. Here, we investigate effect of on inflammation, stress biomarkers, II receptors in duodenum 2K1C rats. Methods: Arterial was induced surgical model. The rats were allocated Sham, 2K1C, or 2K1C+Exercise groups....
