-Previous studies suggested that atrial natriuretic peptide gene (Anp) and brain natriuretic peptide gene (Bnp) are plausible candidate genes for susceptibility to stroke and for sensitivity to brain ischemia in the stroke-prone spontaneously hypertensive rat (SHRSP). We performed structural and functional analyses of these 2 genes in SHRSP from Glasgow colonies (SHRSPGla) and Wistar-Kyoto rats...

Using a specific radioimmunoassay for human brain natriuretic peptide (hBNP) with a monoclonal antibody, we have investigated its synthesis, secretion, and clearance in comparison with those of atrial natriuretic peptide (ANP) in normal subjects and patients with congestive heart failure (CHF). Mean BNP-like immunoreactivity (-LI) levels in normal atrium and ventricle were 250 and 18 pmol/g, re...

OBJECTIVES The aim of this study was to investigate the potential role of brain natriuretic peptide (BNP) levels in the assessment of functional status and right heart performance in primary pulmonary hypertension (PPH). BACKGROUND Primary pulmonary hypertension is a progressive disease leading to right heart failure and death. Right heart catheterization and maximal or submaximal exercise te...

Gene expression and secretion of the cardiac polypeptide hormones atrial natriuretic factor (ANF) and brain natriuretic peptide (BNP) are simultaneously upregulated in various cardiac disorders such as congestive heart failure, ischemic heart disease, and hypertensive heart disease, in which hemodynamic or neuroendocrine changes are key components in the progression of disease. However, during ...

AIMS We examined strategies to improve the positive predictive value of natriuretic peptides in screening for undiagnosed left ventricular systolic dysfunction (LVSD) in the community. METHODS AND RESULTS The value of B-type(BNP), N-terminal proB-type (N-BNP) and N-terminal proAtrial(N-ANP) natriuretic peptides was prospectively assessed in 1360 subjects (45-80 years) together with echocardio...

objectivethis study aimed to assess brain natriuretic peptide in early diagnose of cardiac function in children with congenital heart diseases.methodologythis study was performed on children with chd and healthy. severity of heart failure modified ross classification system was used for grouping patients in four classes. for all participants, height, weight and head circumference were measured....

BACKGROUND Atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP) are a family of structurally related peptides that participate in the integrated control of renal and cardiovascular function. Previous studies suggest a functional role for these hormonal peptides in cardiorenal regulation in congestive heart failure (CHF). METHODS AND RESULTS T...

BACKGROUND Historically, hyponatremia in patients with varying brain diseases was termed cerebral salt wasting. Hyponatremia secondary to CSW was reported to be a distinct entity from SIADH, with the distinguishing feature of decreased extracellular fluid volume. Brain natriuretic peptide, a peptide with natriuretic, vasorelaxant, and aldosterone-inhibiting properties, was recently implicated i...

Atrial natriuretic peptide (ANP) gene expression was localized in the rat gastric antrum using immunohistochemistry and in situ hybridization to mucosal cells in the lower portion of the antropyloric glands. Colocalization of immunoreactive ANP, long-acting natriuretic peptide, i.e., proANP-(1-30), and serotonin in these cells identified them to be enterochromaffin cells. Fasting for 72 h in 8-...
