Background Infertility and fertility decline are quite a conundrum for medicine, rampant among 10-15 percent of couples. In about 40 percent of cases, men are the main culprit. Since sperm production disorders are the focal cause of man infertility, insights into these disorders and taking action to ameliorate the situation is quite vital. The current study concentrates on infertility due to sp...

Health care providers who feel prepared are more apt to assume tobacco interventionist roles; therefore, educational preparation is critical. A nonprobability sample of health professions students at an urban academic health center were asked to respond to a twenty-two-item survey eliciting demographic, behavioral, and tobacco-related attitudinal information. Frequency distributions were assess...

We have observed the presence of membrane junctions formed between the plasma membrane and cortical endoplasmic reticulum of mature, unactivated eggs of xenopus laevis. The parallel, paired membranes of the junction are separated by a 10-mn gap within which electron-dense material is present. This material occurs in patches with an average center-to-center distance of approximately 30 nm. These...

Here we explain a much avoided phenomenon in the evolution of speed sports for men and women: The world records in running tend to be set by black athletes and in swimming by white athletes. We show that this phenomenon is predictable from physics. Locomotion is a ‘falling-forward’ cycle, in which body mass falls forward and then rises again. Mass that falls from a higher altitude falls faster,...

To examine the effects of theophylline toxicity on cardiac rhythm, patients underwent continuous ambulatory ECG recording during acute theophyllme toxicity and recovery. The patients, who were recruited from inpatient wards, intensive care units, and emergency departments of a University Medical Center and a Veterans Administration Medical Center, had serum theophylline concentrations (STC) gre...
