UNLABELLED This study evaluated the reference range and reproducibility of the gastric emptying study with oatmeal as a function of age and sex. METHODS Twenty-four healthy subjects, 12 men and 12 women, categorized into 3 age groups, 20-40, 40-60, and 60-80 y, were studied twice, 1 d apart, with instant oatmeal labeled with (99m)Tc-sulfur colloid. Imaging was performed in the upright positio...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
An 83-year-old woman was scheduled for a second transurethral resection of a bladder tumor. The preoperative electrocardiogram evaluation revealed atrial fibrillation with a slow ventricular response (ventricular rate: 59 /min). After intravenous injection of 1% lidocaine 40 mg and propofol 60 mg, the ventricular rate increased to 113 beats/min and then fell rapidly to 27 beats/min. Blood press...
BACKGROUND [18F]THK5351, a recently-developed positron emission tomography (PET) tracer for measuring tau neurofibrillary tangle accumulation, may help researchers examine aging, disease, and tau pathology in living human brains. We examined THK5351 tracer pharmacokinetics to define an optimal acquisition time for static late images. METHODS Primary measurements were calculation of regional v...
We evaluated the association between kidney dysfunction and sudden cardiac death risk among ambulatory women with coronary heart disease. The Heart and Estrogen Replacement Study evaluated the effects of hormone treatment on cardiovascular events among 2763 postmenopausal women with coronary heart disease. Kidney dysfunction was categorized by estimated glomerular filtration rate (eGFR) using t...
In this study, the extraction parameters of Pinus brutia bark were optimized using a hybrid artificial intelligence technique. Firstly, samples extracted by ultrasound-assisted and microwave-assisted which are defined as âgreenâ methods at different conditions. The selected for 0:100; 20:80; 40:60; 80:20 (%) ethanol: water ratios; 40 ºC, 60 °C temperatures 5 min, 10 15 20 min times 90, 18...
We have examined changes in plasma concentrations of calcium in seven anaesthetized pigs during i.v. infusion of irrigating fluid containing 1.5% glycine. Volumes infused were 875 ml at 20 min (22 ml kg-1), 1475 ml at 40 min and 2075 ml at 60 min (75 ml kg-1). Plasma concentrations of sodium decreased from 134.5 (SD 3.4) to 112.8 (6.7) mmol litre-1 at 60 min and correlated with the volume of gl...
Mechanical performance and 42K exchange were studied during anoxia in isoalted, arterially perfused, interventricular rabbit septa at 42 beats/min and 28 degree C. The septa were perfused at 1.8 ml/min per g with a modified Tyrode solution having dextrose as the metabolic substrate. Developed tension declined to 16% of preanoxic control values during 60 min of anoxia, and returned to 65% of con...
