BACKGROUND The endocrine adrenal gland has 3 zones comprised of the cortex and medulla. The character of multi-hormonal expression results in multiple clinical manifestations. To define the clinical characteristics of adrenal tumors in Taiwan, we reviewed 336 pathologically proven adrenal tumors at Chang Gung Memorial Hospital in Linkou. METHODS We retrospectively analyzed 258 pathologically ...

We introduce parametric equations in the first unit taught in our Pre-Calculus curriculum, immediately after teaching the definition of a function. The use of parametric equations greatly enhances the understanding of domain and range. We start with the students doing explorations on domain and range, using prescribed values for the parameter t. We use this activity not only to re-enforce the c...

OBJECTIVES We evaluated a monotherapy maintenance regimen with lopinavir/ritonavir versus continuing current combined antiretroviral treatment (cART) in HIV patients with suppressed plasma HIV-1 RNA. PATIENTS AND METHODS This was an open-label, non-inferiority, multicentre trial in 23 sites in France. Adults were randomized if they had no history of virological failure while receiving a prote...

This study addresses the problem of sleep apnea recognition on a minute-by-minute basis from single-lead ECGs recorded overnight. Analysis of heart rate fluctuations, quantified by the series of RR-intervals, is compared to analysis of ECG morphology variations, assessed using signal vectors from the QRSand the T-wave region and projecting them onto their first principal component. The resultin...

BACKGROUND Current criterion of waist circumference (WC) for abdominal obesity is not enough to demonstrate characteristics of obese and non-obese populations defined by BMI. The aim of this study was to redefine the cutoff values of WC according to general obesity (BMI ≥ 25 kg/m(2)). METHODS The receiver operating characteristic curve analysis was performed to determine cutoff values of WC f...

The majority of adolescent smokers are able to purchase cigarettes even though laws prohibit the sale of cigarettes to minors (Radecki & Zdunich, 1993). The present study focused on merchant licensing, civil penalties, and monitoring of merchant behavior. Several different schedules of enforcement in the city of Chicago were evaluated to determine the optimal schedules to reduce the sale of cig...

The common alpha subunit of glycoprotein hormones contains five disulfide bonds. Based on the published crystal structure, the assignments are 7-31, 59-87, 10-60, 28-82, and 32-84; the last three comprise the cystine knot, a structure also seen in a variety of growth factors. Previously, we demonstrated that the efficiency of secretion and the ability to form heterodimers by alpha subunits bear...
