background and aims: there has been scant information concerning antihypertrophic effects of vitamin d specifically on its cellular and molecular mechanisms. sirtuin 1 (sirt1) is regarded as a key deacetylase enzyme in cardiomyocytes which applies potential cardioprotective effects by functional regulation of different proteins. this study aimed to evaluate the effects of 1, 25-dihydroxyvitamin...

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-...

BACKGROUND AND PURPOSE Hyponatremia is a common complication after subarachnoid hemorrhage. In this study we investigated the relations among hyponatremia, plasma natriuretic peptides, and antidiuretic hormone concentrations after subarachnoid hemorrhage. METHODS Blood samples for radioimmunoassay measurement of plasma brain natriuretic peptide-like immunoreactivity, atrial natriuretic peptid...

Atrial natriuretic peptides (ANPs) are a family of peptide hormones, e.g., ANP, long-acting natriuretic peptide, vessel dilator, and kaliuretic peptide synthesized by the ANP gene. Brain natriuretic peptide (BNP) and C-type natriuretic peptide are also members of this family but are synthesized by separate genes. Within the kidney, the ANP prohormone's posttranslational processing is different ...

The prevalence of heart failure is increasing. Patients usually present to their general practitioner but a definitive diagnosis of left ventricular systolic dysfunction can only be achieved by cardiac imaging. Measuring plasma concentrations of brain natriuretic peptide has been advocated as a screening test that might reduce demands on cardiological services. We report the results of a commun...

BACKGROUND Resistant hypertension is a common clinical problem and greatly increases the risk of target organ damage. METHODS We evaluated the characteristics of 279 consecutive patients with resistant hypertension (uncontrolled despite the use of 3 antihypertensive agents) and 53 control subjects (with normotension or hypertension controlled by using <or=2 antihypertensive medications). Part...

Hospital admissions with heart failure (HF) are increasing worldwide. It is the main reason for hospitalization of elderly patients. Heart failure affects nearly 15% of patients aged >75 years. Prognosis after diagnosis of HF is comparable to that of cancers with 50% survival after 4 years of mild HF and 50% after one year in more severe cases. Current data increasingly suggest that measurement...

1. Adrenomedullin, a newly identified vasorelaxant peptide, participates in the regulation of the cardiovascular system. To investigate the pathophysiological significance of adrenomedullin in patients with acute myocardial infarction, we measured plasma levels of adrenomedullin. 2. Cardiac catheterization was performed on admission, after 1 day, and after 4 weeks in 36 patients with acute myoc...
