Using the threshold equalizing noise (TEN) test, 49 subjects with at least two pure-tone thresholds per ear greater than 50 dB HL and none greater than 80 dB HL were evaluated for the presence or absence of dead regions. The purpose of this study was to (1) assess the prevalence of cochlear dead regions in this clinical population, (2) measure whether(More)

To date there has been no satisfactory research method for imaging microvascular anatomy in three dimensions (3D). In this article we present a new technique that allows both qualitative and quantitative examination of the microvasculature in 3D. In 10 fresh cadavers (7 females, 3 males, mean age 68 years), selected arteries supplying the abdominal wall and(More)

PURPOSE The purpose of this study was to examine the relationships among characteristics of exercise high-risk situations, components of the RPM relevant to exercise slips, and follow-up(More)
The need to investigate aminothiols such as glutathione (GSH), cysteine (Cys), and homocysteine (Hcy) in blood is stimulated by the current interest in hyperhomocysteinemia as a risk factor for atherosclerosis. Our current goal was to determine whether various cardiovascular (CV) diseases altered levels of GSH and Cys in blood and the relationships between(More)
OBJECTIVE In a large series of patients, we associated the need for preoperative parathyroid hormone (PTH) and calcium levels as a vital component in our approach to the radioguided minimally invasive parathyroidectomy (MIRP) procedure. Our objective was to determine whether these preoperative levels indeed complemented the procedure. Our study also(More)

This study tested the hypothesis that participants with increased knowledge about medical applications of PDAs/smartphones have more positive perceptions of physicians using them. The authors assigned 250 patients and/or family members in(More)
