24 Hour ambulatory blood pressure monitoring (ABPM) was performed to provide data on the normal daily blood pressure of healthy schoolchildren and on patients with hypertension. The subjects studied were 123 healthy schoolchildren with a mean (SD) age of 12.5 (1.6) years (range 9.5-14.5 years), 24 children with borderline or mild hypertension, 17 with renal hypertension and normal renal functio...

Our aim was to investigate motor activity of the healthy, relatively unprepared colon in the ambulatory state. Twenty-five age- and gender-matched adults had a six-sensor solid-state probe inserted into the proximal transverse colon without sedation. Subjects ambulated freely and ate standard meals. In 528 h of recording, we found a lower (P < 0.05) area under the curve during the night. Waking...

background: hydatidosis is one of the most important helminthic diseases causing serious health and economic problems in many countries including iran. currently available diagnostic approaches for diagnosis of cystic echinococcosis (ce) are not satisfactory since they have not achieved a reasonable validity in diagnosis of ce. this study aimed to assess the perform¬ances of western blotting (w...

a study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of yazd. the average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20x mg/day. there is evidence which shows that more important factors than the amount of urinary calcium exist which influence ...

BACKGROUND Smokers have a reduced risk and ex-smokers an increased risk of ulcerative colitis (UC). Stopping smoking often precedes onset and relapses. Smoking reduces the 24 hour urine excretion of oral chromium-51 labelled EDTA in healthy individuals. AIMS To estimate the effects of smoking on the urine excretion of oral 51Cr EDTA in well characterised patients with UC. SUBJECTS Sixteen s...

BACKGROUND Laeverin is a placenta-specific membrane-bound aminopeptidase. In this study we wanted to: 1) serially measure plasma levels of laeverin in healthy women during the second half of pregnancy and postpartum, 2) determine whether laeverin is differently expressed at 22-24 weeks in women who later develop preeclampsia compared to controls, 3) compare laeverin protein expression in placen...

Healthy biological systems exhibit complex patterns of variability that can be described by mathematical chaos. Heart rate variability (HRV) consists of changes in the time intervals between consecutive heartbeats called interbeat intervals (IBIs). A healthy heart is not a metronome. The oscillations of a healthy heart are complex and constantly changing, which allow the cardiovascular system t...
