Fluid volume and osmolality balance are maintained by complex neuroendocrine liquid-salt intake behavior, cardiovascular renal mechanisms, gastrointestinal adjustments. Mechanical stretching of the right atrium (AS) enhances central venous pressure heart rate while decreasing gastric emptying (GE) liquid in rats. We evaluated effect AS on GE plasma levels atrial natriuretic peptide (ANP), oxytocin (OT), corticosterone (CORT) to determine whether ANP contributes OT-mediated delay liquids due...
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....
Ischemia/reperfusion (I/R) injury and metabolic acidosis (MA) are two critical conditions that may simultaneously occur in clinical practice. The result of this combination can be harmful to the kidneys, but issue has not been thoroughly investigated. present study evaluated influence low systemic pH on various parameters kidney function rats were subjected an experimental model renal I/R injury. Metabolic was induced male Wistar by ingesting ammonium chloride (NH4Cl) tap water, beginning 2...
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...
Cardiovascular effects of the linalool‐rich essential oil Aniba rosaeodora (here named as EOAR) in normotensive rats were investigated. In anesthetized rats, intravenous (i.v.) injection EOAR induced dose‐dependent biphasic hypotension and bradycardia. Emphasis was given to first phase (phase 1) cardiovascular effects, which is rapid (onset time 1–3 s) not observed animals submitted bilateral vagotomy or selective blockade neural conduction vagal C‐fibre afferents by perineural treatment...
Physical exercise, mainly after vigorous activity, may induce gastrointestinal dysmotility whose mechanisms are still unknown. We hypothesized that physical exercise and ensuing lactate-related acidemia alter motor behavior. In the present study, we evaluated effects of short-term on gastric emptying rate in awake rats subjected to 15-min swimming sessions against a load equivalent 5% their body weight. After 0, 10, or 20 min testing, were gavage fed with 1.5 ml liquid test meal (0.5 mg/ml...
The aim of the work was evaluate effects testosterone undecanoate (TU) treatment combined with moderate physical training on: estrous cycle, body weight (BW), motor behavior (MB), and morphohistology reproductive system, liver kidney in rats. Female Wistar rats (180 g - 250 g) were divided as follows: sedentary + TU (S TU), trained (T vehicle V), V). swam 50 min/Day, strapped a 5% BW load, for 4 weeks. During this training, (BW) monitored daily well cycle (EC) by vaginal smear. (15 mg/kg...
In the present study, a practical activity is proposed to adopt an experimental approach demonstrate relationship between equilibrium potential for K(+) and transmembrane electrical without glass micropipettes. A conventional setup recording contractile of isolated smooth muscle preparations was used based on events elegantly described by Somlyo in 1960s. They showed that, response given stimulus, cells may contract, recruiting electromechanical or pharmacomechanical coupling mechanisms that...
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...
Homeostasis of blood volume (BV) is attained through a functional interaction between the cardiovascular and renal systems. The gastrointestinal tract also adjusts its permeability motor behavior after acute BV imbalances. We evaluated effect progressive nephron loss on gut motility. Male Wistar rats were subjected or not (sham) to 5/6 partial nephrectomy (PNX) in two steps (0 7th day). After further 3, 7, 14 days, PNX sham operation (control) instrumented monitor mean arterial pressure...
Cisplatin is a chemotherapy agent known for its neurotoxicity. We evaluated the effect of cisplatin on gastric emptying (GE), gastrointestinal (GI) transit liquid, baroreflex function, thermal, and mechanical withdrawal latencies in rats. increased GE liquid with doses ≥ 2 mg.kg(-1) by 59.7-77.4%. This delay was not present two weeks after treatment five at 1 mg.kg(-1). also enhanced gain possibly increasing sympathetic activity. Our results demonstrated that (2-10 mg.kg(-1)) causes...
Abstract Latin America does not have a tradition of higher education evaluation. However, several countries are exploring quality assurance processes, some which include external monitoring. The case Chile is becoming reference in this respect the 1990s. article focuses on main effects or impact evaluation and validation procedures institutional improvement that progress. Particularly, compulsory ‘new private’ university accreditation as well ‘traditional State‐supported’ University...
