Brain and atrial natriuretic peptides (BNP and ANP) are cardiac hormones with diuretic, natriuretic, and vasodilatory activities. Cardiomyopathic hamsters are widely used animal models of heart failure. Due to the structural divergence of BNP among species, examination on pathophysiological roles of BNP using cardiomyopathic hamsters is so far impossible. We therefore isolated hamster BNP and A...

The major class of atrial natriuretic peptide (ANP) receptors was isolated from cultured vascular smooth muscle cells, and a partial amino acid sequence was obtained. This allowed the isolation of cDNA clones from which the entire amino acid sequence was established. The smooth muscle cell ANP receptor appears to be synthesized as a 537-amino acid precursor with an N-terminal membrane transloca...

The effects of synthetic atrial natriuretic peptide (ANP) on the renal hemodynamics, glomerular filtration rate (GFR), fluid and electrolyte excretion and renin release were studied in the isolated perfused rat kidney (IPK). When 10(-9) mol of ANP was administered in 75 ml of perfusate, the renal vascular resistance (RVR) was transiently decreased for 3 to 5 min, thereafter increased for 30 min...

The administration of exogenous atrial natriuretic peptide (ANP) causes a natriuresis and diuresis in man, but this has, to date, only been demonstrated at plasma ANP concentrations within the high pathological or pharmacological ranges. Evidence that ANP acts physiologically requires the demonstration of a natriuretic effect when it is infused to recreate plasma concentrations similar to those...

To examine whether atrial natriuretic polypeptide (ANP) is released from the left ventricle in patients with dilated cardiomyopathy (DCM) we measured plasma ANP level in the aortic root (Ao), the anterior interventricular vein (AIV), the great cardiac vein (GCV), and the coronary sinus (CS) in 11 patients with DCM and 18 control subjects. Plasma ANP levels in Ao, AIV, GCV, and CS were 454 +/- 3...

The effect of acute modifications of pacing mode and rate on plasma ANP levels was evaluated. ANP was determined in ten resting patients with DDD pacemakers due to binodal disease or intermittent second-and third-degree AV block. At 82/minute pacing rate the ANP plasma levels (normal range 2 to 30 fmol/mL) corresponded to those under AAI (4.05 +/- 2.10 fmol/mL) and DDD (4.18 +/- 2.02 fmol/mL) p...

Nowadays most required products and services of companies are provided through other organisations. Outsourcing as a new approach has a significant role in management literature. Supplier should be selected by executives, when the organization decides to acquire a product or service from other organizations. Concerning supplier selection, the managers should consider more than one factor or cri...

Imidazoline receptors are divided into I(1) and I(2) subtypes. I(1)-imidazoline receptors are distributed in the heart and are upregulated during hypertension or heart failure. The aim of this study was to define the possible role of I(1)-imidazoline receptors in the regulation of atrial natriuretic peptide (ANP) release in hypertrophied atria. Experiments were performed on isolated, perfused, ...

OBJECTIVES Intestinal barrier dysfunction plays an important role in acute necrotizing pancreatitis (ANP) and intestinal microbiota dysbiosis was involved in intestinal barrier failure. Paneth cells protect intestinal barrier and are associated with intestinal microbiota. Here, we investigated changes in intestinal microbiota and antimicrobial peptides of Paneth cells in ileum during ANP. MET...

OBJECTIVES We hypothesized that the plasma atrial natriuretic peptide (ANP) level reflects atrial degenerative change and may predict the outcome of the maze procedure. BACKGROUND Although a larger preoperative left atrial dimension and longer duration of atrial fibrillation (AF) have been reported in patients with persistent AF than in those with sinus rhythm (SR), these individual factors w...
