BACKGROUND Elevated resting pulmonary arterial pressure (PAP) in patients with left ventricular systolic dysfunction (LVSD) purports a poor prognosis. However, PAP response patterns to exercise in LVSD and their relationship to functional capacity and outcomes have not been characterized. METHODS AND RESULTS Sixty consecutive patients with LVSD (age 60±12 years, left ventricular ejection frac...

background: phosphatidate phosphohydrolase (pap) catalyzes the dephosphorylation of phosphatidic acid to yield p i and diacylglycerol. two different forms of pap have been reported in rat hepatocyte: pap 1 that participates in the synthesis of phospholipids and triacylglycerols and pap 2 which is involved in lipid signaling pathways. two isoforms of pap 2 are pap 2a and pap 2b . this study exam...

Fractional flow reserve (FFR) is considered the standard for assessment of physiological significance coronary artery stenosis. Intracoronary papaverine (PAP) most potent vasodilator used achievement maximal hyperemia. However, its use can provoke ventricular tachycardia (VT) due to excessive QT prolongation. We evaluated clinical efficacy and safety administration PAP after nicorandil (NIC), a...

objective(s): in developing countries and worldwide cervical cancer is an important cause of   female mortality. reports describing the frequency and pattern of abnormal pap smears in saudi arabia, using the revised bethesda system (rbs) are very few. the current study was conducted to explore the changing pattern of epithelial cell abnormalities (eca) detected in pap smears (ps) in females of ...

With the sharp rise in global interest sustainability and environmental concerns, there is a growing demand replacing petroleum-derived raw materials with renewable plant-based production of polymers. In this study, two palm fatty acid polyesters were synthesized from palmitic stearic acids. Their chemical structures identified by FTIR 1H-NMR analysis. Both showed moderately high conversion rat...

background: colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. objectives: in order to evaluate molecular epidemiologyof some virulence associated factors in escherichia coli,isolated from poultry, the presence of iut a, iss, hly f, omp t, iron, afa, sfa (s)and pap g (ii) were investigated by multiplex pcrassay. methods: two hundred th...
