BACKGROUND Type-2 diabetic patients exhibit postprandial hypertriglyceridemia, a risk factor for atherosclerosis. Several inflammatory markers are also risk factors for atherosclerosis, such as ultrasensitive C-reactive protein (CRP) and number of leukocytes. There is a relationship between the increase in triglycerides and that of leukocytes in the(More)
Sildenafil slows down the gastric emptying of a liquid test meal in awake rats and inhibits the contractility of intestinal tissue strips. We studied the acute effects of sildenafil on in vivo intestinal transit in rats. Fasted, male albino rats (180-220 g, N = 44) were treated (0.2 mL, iv) with sildenafil (4 mg/kg) or vehicle (0.01 N HCl). Ten minutes(More)
Major clinical studies have shown that the targets for blood glucose, lipid profile and blood pressure in type 2 diabetic patients are difficult to maintain in clinical practice. However, there are few data concerning South American populations. Using guidelines represented by the Brazilian Diabetes Society, we evaluated cardiovascular (CV) risk factors,(More)
UNLABELLED According to Brazilian National Data Survey diabetes is the fifth cause for hospitalization and is one of the ten major causes of mortality in this country. AIMS to stratify the estimated cardiovascular risk (eCVR) in a population of type 2 diabetics (T2DM) according to the Framingham prediction equations as well as to determine the association(More)
We evaluated the effects of cyclooxygenase-2 (COX-2) selective inhibitors, COX-1 selective inhibitor, or COX non-selective inhibitor on gastric emptying and intestinal transit of liquids, and evaluated the effect of a COX-2 selective inhibitor on gastric tonus (GT). Male Wistar rats were treated per os with saline (control), rofecoxib, celecoxib, ketorolac,(More)
The present study analysed the effect of protein restriction on serum insulin and leptin levels and their relationship with energy balance during lactation. Four groups of rats received isocaloric diets containing 170 g protein/kg or 60 g protein/kg from pregnancy until the 14th day of lactation: control non-lactating, control lactating (both fed a control(More)
AIM To evaluate the prevalence of overweight and obesity in type 2 diabetic (DM2) outpatients from different regions of Brazil. PATIENTS AND METHODS We studied 2,519 randomly selected patients, from 11 hospitals, 2 endocrine and one general public care clinics from 10 cities. Overweight was defined as body-mass index (BMI) > 25 and obesity as BMI > 30(More)
AIM Stapled haemorrhoidopexy may damage the anorectal musculature and its sensorimotor function. Most studies have not used a barostat for the measurement of compliance. This study aimed to investigate the effect of stapled haemorrhoidopexy on rectal compliance and sensitivity. METHOD After Ethical Committee approval, we studied 10 male patients (mean age(More)
