Background. Airway pressure release ventilation (APRV) is a mode of mechanical ventilation that theoretically believed to improve cardiac output by lowering right atrial pressure. However, hemodynamic parameters have never been formally assessed. Methods. Seven healthy swine were intubated and sedated. A baseline assessment of conventional ventilation (assist control) and positive end-expirator...

BACKGROUND Lipid accumulation product (LAP) has been advocated as a simple clinical indicator of metabolic syndrome (MS). However, no studies have evaluated the accuracy of LAP in predicting MS in Taiwanese adults. The aim of our investigation was to use LAP to predict MS in Taiwanese adults. METHODS Taiwanese adults aged 50 years and over (n = 513) were recruited from a physical examination ...

To detect viral infections and tumors, CD8+ T lymphocytes monitor cells for the presence of antigenic peptides bound to MHC class I molecules. The majority of MHC class I-presented peptides are generated from the cleavage of cellular and viral proteins by the ubiquitin-proteasome pathway. Many of the oligopeptides produced by this process are too long to stably bind to MHC class I molecules and...

Background The increase in the prevalence of obesity worldwide has led to non-alcoholic fatty liver disease (NAFLD) becoming one of the most common causes of chronic liver disease. Chemerin is a novel adipokine which regulates adipogenesis which is also a marker of systemic and vascular inflammation. Lipid accumulation product (LAP) is associated with the presenc...

Since its inception Language Action Perspective (LAP) has made significant progress in developing ontological and epistemological theories of information systems, new modeling approaches and tools, or new computer based coordination tools. In some sense LAP has come of age and can be regarded a specific computing movement, or a unique discourse and voice in the information technology revolution...

Background The ratio of the transmitral early inflow velocity (E wave) and the tissue Doppler mitral annular velocity (e’ wave) can be used to measure left atrial pressure on the echocardiographic examination. An elevated E/e’ (>15) on echo Doppler is an established measure of elevated LAP. Unlike echo, cardiac MRI (CMR) has no non-invasive measure of LAP. Normally both the atrioventricular val...

Serum leucine-aminopeptidase (LAP) and cystine-aminopeptidase (CAP) determinations have been made using a chemical method based on enzymatic hydrolysis of l-leucine-/?-naphthylamide-hydrochloride and cystine-di-/?naphthylamide, respectively. Fractionation of serum proteins by gel filtration on "Sephadex-G 200" has been used for separation of LAP and CAP (oxytocinase). — CAP which appears during...

The phosphorylation state of transcription factors is a critical determinant of their function. C/EBPbeta occurs in cells as the transcriptional activator liver-enriched activating protein (LAP) and in the truncated form liver-enriched inhibitory protein (LIP) that inhibits transcription. Analysis of C/EBPbeta phosphorylation by isoelectric focusing (IEF) shows that LAP is present in multiple f...

BACKGROUND Body mass index (BMI, kg/m2) may not be the best marker for estimating the risk of obesity-related disease. Consistent with physiologic observations, an alternative index uses waist circumference (WC) and fasting triglycerides (TG) concentration to describe lipid overaccumulation. METHODS The WC (estimated population minimum 65 cm for men and 58 cm for women) and TG concentration f...

BACKGROUND One of the purposes of treatment for dogs with mitral regurgitation (MR) is lowering left atrial pressure (LAP). There has been few study of the amlodipine in dogs with MR and amlodipine's effect on LAP has not been fully evaluated in a quantitative manner because of difficulties in directly measuring LAP. The objective of our study was to compare the short-term effects of amlodipine...
