Advanced glycation end products (AGEs), the final products of nonenzymatic glycation and oxidation of proteins, are found in the plasma and accumulate in the tissues during aging and at an accelerated rate in diabetes. A novel integral membrane protein, termed receptor for AGE (RAGE), forms a central part of the cell surface binding site for AGEs. Using(More)
We hypothesized that one mechanism underlying advanced periodontal disease in diabetes may involve oxidant stress in the gingiva, induced by the effects of Advanced Glycation Endproducts (AGEs), the irreversible products of non-enzymatic glycation and oxidation of proteins and lipids which accumulate in diabetic plasma and tissue. Infusion of AGE albumin, a(More)
OBJECTIVE To compare results from testosterone radioimmunoassay kits commonly used by commercial laboratories as well as their reference ranges and to analyze the scientific literature for ranges of serum testosterone levels in normal women and those with hyperandrogenism. METHODS We reviewed quality assurance reports of various testosterone ligand(More)
Hyperandrogenism is a common disorder in the reproductive age female. It is associated with cutaneous manifestations and ovulatory dysfunction. The degree of hyperandrogenaemia is directly related to the severity of ovulatory dysfunction. The ovulatory dysfunction frequently leads to infertility. The most common form of hyperandrogenism is idiopathic(More)
Dead and dying cells were localized by light microscopy in the mucosal epithelium of the intestine of an outbred strain (CD1) and an inbred strain (B10A) of mice by vital staining with the dye, trypan blue. In whole mounts of the intestinal wall, trails, or variable-sized clusters of blue-stained cells were seen throughout the course of infection and in(More)
RATIONALE AND OBJECTIVES Diagnostic radiology chief residents were surveyed on issues related to residency training to compare features and gauge trends in training. METHODS Questionnaires were mailed to accredited programs in the United States. A variety of demographic and common-interest questions were asked. RESULTS Forty-three percent of surveys(More)
HYPOTHESIS Recent use of minimally invasive techniques to evaluate the chest and abdomen in patients with penetrating thoracoabdominal trauma has led to the discovery of many occult diaphragm injuries. Surgical repair of these injuries is relatively straightforward. However, diagnosis can be difficult, and the natural history of these injuries is(More)
Thirty-seven infants with myelomeningocele received brainstem auditory evoked potentials (BAEPs) at a median age of eight days. No infant had brainstem dysfunction at the time of testing. Median follow-up was at 30 months. Of 12 infants who subsequently developed brainstem dysfunction at a median age of three months, 11 had had abnormal neonatal BAEPs. In(More)
Using 31P spectroscopy and magnetic resonance imaging (MRI), the authors studied changes in muscle phosphorous metabolites and T2 with isometric knee extension to evaluate the potential role of T2 images in coil placement for exercise spectroscopy studies. Increased signal intensity was visible in active muscles on T2 images after exercise. Calculated(More)
