OBJECTIVE To determine the levels of NT-pro BNP in HIV patients over 40 years who are receiving highly active antiretroviral therapy (HAART) and investigating potential independent clinical or laboratory factors. METHOD We determine levels of NT-pro BNP in peripheral blood of HIV patients from Costa del Sol Hospital, over 40 years. We collected epidemiological, classical cardiovascular risk f...

A prospective study was performed to evaluate the diagnostic accuracy of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) levels, measured simultaneously in serum and pleural fluid, in identifying pleural effusions due to heart failure. Pleural fluid and serum samples from all patients presenting for thoracentesis between April 2004 and May 2005 were simultaneously collected. The discrimin...

Peptide synthesis is widely used for the production of small proteins and peptides, but producing uniformly isotopically labelled peptides for NMR and other biophysical studies could be limited for economic reasons. Here, we propose a use of a modified pGEV-1 plasmid to express neurotensin (NT(1-13)), pGlu(1)-Leu(2)-Tyr(3)-Glu(4)-Asn(5)-Lys(6)-Pro(7)-Arg(8)-Arg(9)-Pro(10)-Tyr(11)-Ile(12)-Leu(13...

B-type natriuretic peptide (BNP) is a member of a fournatriuretic peptide family that shares a common 17-peptide ring structure. The N-terminal fragment (NT-pro-BNP) is biologically inert, but both are secreted in the plasma in equimolar quantities and both have been evaluated for use in the management of congestive heart failure. BNP and NT-pro-BNP are frequently used in the diagnosis of conge...

BACKGROUND The Zwolle Risk Score (ZRS) identifies ST-elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PPCI) eligible for early discharge. We aimed to investigate whether baseline N-terminal pro-brain natriuretic peptide (NT-proBNP) is also able to identify these patients and could improve future risk strategies. METHODS AND RESULTS PPCI...

BACKGROUND The prognostic significance of chest pain is well established in patients with coronary artery disease, but still ill defined in primary prevention. Therefore, the aim of our analysis was to assess the prognostic value of different forms of chest pain in a large cohort of primary care subjects under the conditions of contemporary modalities of care in primary prevention, including me...

BACKGROUND Genetic and epidemiological evidence suggests an inverse association between B-type natriuretic peptide (BNP) levels in blood and risk of type 2 diabetes (T2D), but the prospective association of BNP with T2D is uncertain, and it is unclear whether the association is confounded. METHODS AND FINDINGS We analysed the association between levels of the N-terminal fragment of pro-BNP (N...

INTRODUCTION It is unclear whether the fluid status, as determined by bioimpedance vector analysis (BIVA) combined with serum N-terminal pro-B-type natriuretic peptides (NT-pro-BNP) measurement, is associated with treatment outcome among patients receiving continuous renal replacement therapy (CRRT). Our objective was to answer this question. METHODS Patients who were in the intensive care un...

Among the members of the proprotein convertase (PC) family, PC1 and PC2 have well established roles as prohormone convertases. Another good candidate for this role is PC5-A that has been shown to be present in the regulated secretory pathway of certain neuroendocrine tissues, but evidence that it can process prohormones is lacking. To determine whether PC5-A could function as a prohormone conve...
