During adolescence, there is a tendency to sleep late and sleep less because of altered psychosocial and life-style changes. Recent studies have demonstrated the link between sleeping less and gaining weight in children, adolescents, and adults. We studied the effect of late sleeping and sleeping less on body mass index (BMI) in medical college freshmen. All participants were adolescents (104 m...

Because methionine enkephalin contributes to and dynorphin opposes dilation during a 10-min hypoxic exposure, opioids modulate pial artery dilation to this stimulus. However, such modulation may be dependent on the duration of hypoxia. The present study was designed to characterize the modulation of hypoxic pial dilation by opioids as a function of stimulus duration in newborn pigs equipped wit...

This study was undertaken to determine the relationships between myocardial mitochondrial function, regional myocardial blood flow (MBF), and tissue ATP content in acute ischemia. Fifty-one anesthetized dogs were used in the tests. MBF was measured by the H2 gas clearance method in order to define the ischemic area, during periods of coronary occlusion of 10, 20, 60, and 90 min. The correlation...

The aims of this study were (a) to establish the occurrence, duration and intensity of behavioral estrus symptoms, and (b) to determine the relationship between behavioral estrus symptoms with the total estrogen profiles in cycling Murrah buffaloes (n=10) subjected to Doublesynch protocol (0 PGF2α, 2 GnRH, 9 PGF2α and 11 GnRH). After both GnRH injections, estrus and its behavioral signs were de...

The time-course of the rate of oxygen consumption (QO2) has been measured in the excised frog sartorius muscle after single isometric tetani of 0.1-1.0 s at 20 degrees C. To measure deltaQO2(t), the change in QO2 from its basal level, a novel method was devised, based on the validity in this tissue of the one-dimensional diffusion equation for oxygen, established in the preceding paper. After a...
