BACKGROUND Syncopal episodes are common among older adults; etiologies range from benign to life threatening. We determined the frequency, yield, and costs of tests obtained to evaluate older persons with syncope. We also calculated the cost per test yield and determined whether the San Francisco syncope rule (SFSR) improved test yield. METHODS Review of(More)
In humans, intracytoplasmic sperm injection (ICSI) has become widely applied to overcome infertility. In addition to its clinical usefulness, ICSI is also a valuable research tool for studying fundamental aspects of gamete interaction during fertilization. Oocyte activation is a prerequisite for decondensation of the sperm head and formation of the male(More)
Fructose tolerance tests were applied to 54 piglets, aged between zero and 20 hours, two and three, five and seven, as well as 20 and 30 days. Fructose injections per kilogram of body weight were 0.5 g and 1.0 g. Galactose tolerance tests were applied to 33 piglets, aged between zero and 20 hours as well as between five and seven or 20 and 35 days. The(More)
Single glucose doses of 0.5 g/kg body weight or 1.0 g/kg were intravenously applied at ambient temperatures between 25 degrees C and 30 degrees C pigs aged between zero and 20 hours two and three, five and seven, ten and 14, 20 and 30 days, and eight weeks. With reference to excess glucose curves in the blood and plasma, the half-life of glucose elimination(More)
