BACKGROUND Normal endothelial function is a measure of vascular health and dysfunction is a predictor of coronary events. Nitric oxide-mediated coronary artery endothelial function, as assessed by vasomotor reactivity during isometric handgrip exercise (IHE), was recently quantified noninvasively with magnetic resonance imaging (MRI). Because the internal mammary artery (IMA) is often visualize...

Live High:Train Low (LHTL) altitude training is a popular ergogenic aid amongst athletes. An alternative hypoxia protocol, acute (60-90 min daily) Intermittent Hypoxic Exposure (IHE), has shown potential for improving athletic performance. The aim of this study was to compare directly the effects of LHTL and IHE on the running and blood characteristics of elite triathletes. Changes in total hae...

Adaptive Histogram Equalization (AHE) often introduces artifacts, for example at the edges of relatively homogeneous regions. In this contribution we propose a variation of global histogram equalization, that avoids these artifacts. The method which is called Interactive Histogram Equalization (IHE) is based on a simpler calculation than AHE. IHE can be a serious competitor for the established ...

Intramural hematoma of the esophagus (IHE) is an uncommon form of esophageal injury, which may be an intermediate of mucosal tear (Mallory-Weiss syndrome) or transmural rupture (Boerhaave's syndrome). To date, the pathogenesis of IHE has not been well documented. IHE may occur within the submucosal layer of the esophagus following dissection of the mucosa. The most commonly presented symptoms a...

The effect of i.v. injection of mevalonate on the activity of microsomal 3-hydroxy-3-methylglutaryl Conenzyme A reduc Ã-asewas studied in livers from non-tumor-bearing rats and in host liver and hepatomas from rats bearing transplantable Morris hepatoma 7800. We confirmed that a single bolus injection of 100 mg of mevalonate in non-tumor-bearing male rats caused a 90% inhibition of hepatic 3-hy...

pacs is used as a way to store images and matches well with the workflow in the radiology department and can spread to other parts of hospital. integration with other pacs and other hospital systems like radiology information system (ris), hospital information system (his), and electronic patient records has been completely done, but there are still problems. pacs also provide good conditions f...

This paper proposes a new analytical approach f o r evaluating ihe effects of a repair process on the defect level of multichip module ( M C M ) systems ai assembly. Repair of M C M s is usually required to improve the yield and quality of ihese systems, while preserving cost effectiveness. In the proposed approach, we develop a novel quality model, which is solved analytically in O ( r N 3 ) (...

Endothelial cell release of nitric oxide (NO) is a defining characteristic of nondiseased arteries, and abnormal endothelial NO release is both a marker of early atherosclerosis and a predictor of its progression and future events. Healthy coronaries respond to endothelial-dependent stressors with vasodilatation and increased coronary blood flow (CBF), but those with endothelial dysfunction res...
