The aim of this study was to develop and validate a fast and simple reversed-phase HPLC method for simultaneous determination of four cardiovascular agents-atorvastatin, simvastatin, telmisartan and irbesartan in bulk drugs and tablet oral dosage forms. The chromatographic separation was accomplished by using Symmetry C18 column (75 mm × 4.6 mm; 3.5 μ) with a mobile phase consisting of ammonium...

BACKGROUND A substantial proportion of patients receiving fibrinolytic therapy for myocardial infarction with ST-segment elevation have inadequate reperfusion or reocclusion of the infarct-related artery, leading to an increased risk of complications and death. METHODS We enrolled 3491 patients, 18 to 75 years of age, who presented within 12 hours after the onset of an ST-elevation myocardial...

W hen will it be done? " Senior managers will ask their software project managers this question more than 250,000 times this year. Corporations, which collectively commit over US$300 billion annually toward new software project initiatives, 1 will want to know the answer. However, when you consider Barry Boehm's claim that early software life-cycle estimates vary by a factor of four (25 to 400 ...

This report proposes a standard method to characterize variability and sensitivity of functional neuroimaging experiments. Most functional neuroimaging analyses result in statistic images of signal-to-noise. However, it is essential to examine both signal and noise individually, to characterize sensitivity and to identify artifacts. Confidence intervals simultaneous convey signal and noise but ...

PURPOSE Gastroenterologists have been seeking reliable noninvasive indices of inflammatory and malignant bowel disease. This prospective study was to assess the value of fecal calprotectin in predicting abnormal histologic findings in patients undergoing colonoscopy. METHODS Stool specimens supplied before colonoscopy by 72 consecutive patients were measured for calprotectin levels, and the f...

BACKGROUND Medline is one of the most important databases in the biomedical field. One of the most important hosts for Medline is Elton B. Stephens CO. (EBSCO), which has presented different search methods that can be used based on the needs of the users. Visual search and MeSH-controlled search methods are among the most common methods. The goal of this research was to compare the precision of...
