r-phycoerythrin (r-pe), a fluorescent protein from phycobiliprotein family, is isolated from red algae. conjugation of antibodies to r-pe facilitates multiple fluorescent staining methods. in the present study polyclonal antibodies and polyclonal f(ab')2 fragment antibodies were conjugated to r-pe by two different methods. the efficiency of the methods was evaluated using immunocytochemistry (i...
OBJECTIVES The optimal therapy for hypertriglyceridemic acute pancreatitis, especially the role of plasma exchange (PE), is not entirely clear. The aim of our large, single-center, observational, cohort study was to analyze the factors affecting outcome in hypertriglyceridemic pancreatitis treated with PE. METHODS We included 111 episodes of hypertriglyceridemic pancreatitis treated with PE, ...
INTRODUCTION Overuse of CT Pulmonary Angiograms (CTPA) for diagnosing pulmonary embolism (PE), particularly in Emergency Departments (ED), is considered problematic. Marked variations in positive CTPA rates are reported, with American 4-10% yields driving most concerns. Higher resolution CTPA may increase sub-segmental PE (SSPE) diagnoses, which may be up to 40% false positive. Excessive use an...
BACKGROUND Previous research has shown that pharmacoeconomic (PE) data are considered important but may not be optimally utilized by decision makers. No research has compared the effectiveness of different types of PE models. OBJECTIVES The purpose of this study was to examine the perceived value and understanding of PE models among decision makers in managed care organizations. The perspecti...
OBJECTIVE To compare the performance of screening by soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) ratio > 38 for the prediction of delivery with pre-eclampsia (PE) at < 1 week and < 4 weeks from assessment when the test is carried out at 31-34 vs 35-37 weeks' gestation. METHODS This was a prospective observational study in women attending a third-trimester ult...
Pulmonary embolism (PE) remains a challenge for any physician because its clinical presentation covers a broad spectrum and is often similar to other cardio-pulmonary disorders. PE is still under-diagnosed due to it’s various/atypical clinical presentations, the dynamic of embolic processes and due to the fact that we have several diagnostic methods without 100% sensitivity and specificity. Abo...
To better understand the molecular basis for increased atrial natriuretic factor (ANF) and brain natriuretic peptide (BNP) expression during overload-induced cardiac hypertrophy, we studied the induction of the genes in primary myocardial cells by the alpha 1-adrenergic agonist, phenylephrine (PE), a potent hypertrophic agent. PE augmented the transcription of both genes to similar extents, alt...
Background. Pulmonary embolism (PE) is clinically suspected in many patients who complain of shortness of breath or chest pain due to its nonspecific nature. The prevalence of PE, however, is low in this population. To assist physicians in diagnostic decision making, several clinical decision rules (CDR) have been developed. The appropriate use of these CDRs has been proven to decrease the need...
BACKGROUND AND OBJECTIVES Physical examination (PE) skills among U.S. medical students have been shown to be deficient. This study examines the effect of a Web-based physical examination curriculum on first-year medical student PE skills. METHODS Web-based video clips, consisting of instruction in 77 elements of the physical examination, were created using Microsoft Windows Moviemaker softwar...
