The purpose of this study was: 1) to compare the
change in QT interval values before, during, and after
exercise following carbohydrate depletion and loading, and
2) to assess the change following vitamin B-6 supplementation.
ECG monitoring devices and bicycle ergometers were
used to collect ECG tracings and control the...
The endocrine mechanisms involved in the initiation of sperm release
from the vertebrate testis have not been elucidated. A seasonally
breeding anuran amphibian, Hyla regilla, was selected as a model for
testing the hypothesis that steroid action is involved in gonadotropin-stimulated
sperm release. Experiments were carried out in vivo and...
Perinatal growth restriction programs higher risk for chronic disease during adulthood via morphological and physiological changes in organ systems. Perinatal growth restriction is highly correlated with a decreased nephron number, altered renal function and subsequent hypertension. I hypothesize that such renal maladaptations result in altered pharmacologic patterns for life. Pregnant...
