The patient (male, tet. 35), when admitted to hospital, 2Gth December, 1913, was suffering from intense pain over the greater part of the abdomen, of which the respiratory movements were somewhat restricted. There was no visible peristalsis. On palpation there was some tenderness. No tumour could be felt. The temperature was 101*4 and the pulse 120. The only history which could be obtained from...

The aim of this study was to assess the changes in insulin secretion and insulin sensitivity in relation to fasting and 2-hour plasma glucose (PG) levels and to assess the independent contributions of their impairments to non-diabetic hyperglycemia. A total of 2157 Japanese workers (mean age 52.6±7.3 years and mean BMI 23.9±3.2 kg/m(2)) underwent an oral glucose tolerance test (OGTT). Of thes...

Cytokinesis in budding yeast involves an actomyosin-based ring which assembles in a multistepped fashion during the cell cycle and constricts during cytokinesis. In this report, we have investigated the structural and regulatory events that occur at the onset of cytokinesis. The septins, which form an hour-glass like structure during early stages of the cell cycle, undergo dynamic rearrangement...

The influence of in vivo melatonin administration on in vitro pituitary follicle stimulating hormone (FSH), growth hormone (GH) and prolactin secretion, as well as the possible influence of dopamine (DA) were evaluated in prepubertal (31-day-old), pubertal (33-day-old) and adult female rats at diestrus phase of the sexual cycle. The in vitro pituitary hormone secretions were evaluated at basal ...

We hypothesized that decrements in maximum power output (W(max)) of the rat diaphragm (Dia) muscle with repetitive activation are due to a disproportionate reduction in force (force fatigue) compared with a slowing of shortening velocity (velocity fatigue). Segments of midcostal Dia muscle were mounted in vitro (26 degrees C) and stimulated directly at 75 Hz in 400-ms-duration trains repeated e...

BACKGROUND It is generally accepted that physical training decreases blood pressure in hypertensive subjects, but the importance of training intensity has not been established. This study compared the effects of endurance training at different intensities on ambulatory blood pressure and on blood pressure load (percentage of readings above 140/90 and 120/80 mm Hg during the waking and sleeping ...

The effects of cryoextraction on transport characteristics of rabbit lenses were evaluated by measuring Na+ and Ca++ levels, initial rates of 86Rb accumulation, and bioelectric potentials. The results demonstrate that membrane damage results from cryoextraction and is partially reversible during subsequent culture. While the decline in potential often exceeds 30 mV, maximum recovery of 80% occu...

Increased plasma norepinephrine levels have been observed in some persons with early essential hypertension. Although both plasma norepinephrine level and mean arterial blood pressure rise with age, little is known about the state of catecholamine secretion in elderly patients with essential hypertension. We studied the 24-hour cycle levels of plasma norepinephrine, epinephrine, and dopamine in...

OBJECTIVE: Since bread is the main source of food in Iran, we aimed to assess the effect of four types of Iranian breads on metabolic and cardiovascular responses before and during 15, 30, 60, 90, 120 and 180 minutes of consumption in type 2 diabetic patients. MATERIALS AND METHODS: Ten type 2 diabetic patients (6 women and 4 men) with mean age of 51 ± 9.8 years and mean BMI of 31.9 ± 1.19 kg/...
