Screening for carriage of methicillin-resistant Staphylococcus aureus (MRSA) is fundamental to modern-day nosocomial infection control, both for epidemiologic investigation and day-to-day decisions on barrier isolation. Numerous microbiologic techniques have been advocated for screening for nasal carriage of MRSA, including the use of charcoal rather than rayon swabs, preincubation of swabs in ...

Oxidized low-density lipoprotein (ox-LDL) plays a critical role in the development of atherosclerosis. Recent studies show that ox-LDL may induce apoptosis of cultured rabbit smooth muscle cells and human macrophages. This study was designed to determine the modulation by ox-LDL of apoptosis in cultured human coronary arterial endothelial cells (HCAEC) during hypoxia-reoxygenation and to determ...

PURPOSE To investigate whether oxidized low-density lipoprotein (Ox-LDL) affects endothelium-dependent responses in isolated porcine ciliary arteries. METHODS In a myograph system for isometric force measurements, quiescent vessels were incubated with 50 microg/ml, 100 microg/ml, or 200 microg/ml Ox-LDL; 100 microg/ml native LDL (n-LDL); 1 microM of the ET(A)- endothelin receptor antagonist B...

A monoclonal antibody called MRC OX-44 is described that labels all myeloid cells and peripheral lymphoid cells but only 12% of thymocytes. The OX-44+ thymic cells include most if not all cells found in the medulla but only a small fraction of the cortical cells. Together with CD4 and CD8 antigens, seven subsets of thymic cell were defined and it was notable that most CD4- CD8- cells were OX-44...

objective(s) oxidized low-density lipoproteins (ox-ldls) appear to play a significant role in atherogenesis. in fact, circulating ox-ldl concentrations have been recognized as a risk factor for cardiovascular disease (cvd). the main objectives of this study were to assess the effects of antioxidant vitamins on ox-ldl as a biomarker of cvd in male subjects with cvd risk factors. materials and me...

background: hyperlipidemia and oxidized-low-density lipoproteins (ox-ldl) are important independent cardiovascular risk factors that have been shown to stimulate vascular smooth muscle cell (vsmc) proliferation. the purpose of the present study was to investigate the effect of vitamin e on ox-ldl, lipid profile, c-reactive protein (crp), and vsmc proliferation of rat aorta. methods: male wistar...

OBJECTIVE Circulating oxidized LDL (Ox-LDL) is associated with clinical manifestations of atherosclerosis. However, no previous study has examined the relationship between subclinical atherosclerosis and Ox-LDL. The aims of the present study were to investigate the relationship between clinically silent ultrasound-assessed atherosclerotic changes in the carotid and femoral arteries and Ox-LDL a...

Vascular calcification is associated with significant cardiovascular morbidity and mortality, and has been demonstrated as an actively regulated process resembling bone formation. Oxidized low density lipoprotein (Ox-LDL) has been identified as a regulatory factor involved in calcification of vascular smooth muscle cells (VSMCs). Additionally, over-expression of recombinant human neutral sphing...

Objective. To evaluate the effectiveness of oxandrolone in improving the nutritional status and linear growth of pediatric patients with cystic fibrosis (CF). Methods. Medical records of patients with CF treated with oxandrolone were reviewed for height z score, height velocity (HV), BMI z score, weight velocity (WV), Tanner stage, pulmonary function, liver enzyme levels, and any reported adver...

Oxidized low density lipoprotein (Ox-LDL) induces apoptosis in vascular smooth muscle cells (VSMCs), which may increase atherosclerotic plaque instability. In this study, we examined the molecular mechanisms causing the Ox-LDL-induced apoptosis in VSMCs, especially focusing on the involvement of Bax/Bcl-2 and the lectinlike Ox-LDL receptor-1 (LOX-1). In cultured bovine aortic smooth muscle cell...
