Atrial natriuretic peptides (ANP) have recently been identified in both heart and CNS. These peptides possess potent natriuretic, diuretic, and vasorelaxant activities, and are all apparently derived from a single prohormone. Specific ANP binding sites have been characterized in the adrenal zona glomerulosa and kidney cortex, and one study reported ANP binding sites in the CNS. However, a detai...

The aim of the current study was to present the spatial distribution of atrial natriuretic peptide (ANP) in short-term cultures of pig granulosa cells obtained from small, medium, and large ovarian follicles. The specific immunoreactivity was detected by three monoclonal antibodies recognizing different epitopes of the ANP molecule (Mab 6C3, Mab 6F11, Mab5D3). The specific ANP immunoreactivity ...

BACKGROUND The hormone atrial natriuretic peptide (ANP) causes bronchodilation and partially protects against direct and indirect bronchial challenges. Both in vitro and in vivo studies have found that the protective effect of ANP against bronchoconstriction is enhanced by inhibition of the enzyme neutral endopeptidase (NEP). It was hypothesised that pretreatment with thiorphan, an NEP inhibito...

M-atrial natriuretic peptide (ANP; M-ANP) is a novel next generation 40 amino acid peptide based on ANP, which is highly resistant to enzymatic degradation and has greater and more sustained beneficial actions compared with ANP. The current study was designed to advance our understanding of the therapeutic potential of M-ANP in a canine model of acute angiotensin II–induced hypertension with el...

تخصیص دارایی فرایند توزیع سرمایه در میان گونه‌های مختلفی از دارایی‌ها مانند نقد، اوراق قرضه، سهام، کالاها و ... است که به منظور بهینه نمودن موازنه‌ی ریسک-بازده بر اساس موقعیت و اهداف مشخص سرمایه‌گذار نهادی/فردی صورت می‌گیرد. تخصیص دارایی نخستین گام در تشکیل سبد سرمایه‌گذاری و یک مفهوم کلیدی در مدیریت پول و برنامه¬ریزی مالی است. با نگاهی به ادبیات این موضوع، با پژوهش‌هایی روبرو می‌شویم که اکثر آ...

Atrial wall stretching is a known stimulus for atrial natriuretic peptide (ANP) secretion. The effects of the stimulation of autonomic nervous system, hemodynamic factors, and humoral factors (epinephrine, angiotensin, vasopressin, and brain extracts) on the release of ANP under basal conditions and during increased atrial pressure produced by acute volume loading in pithed rats were examined. ...

To explore whether pathophysiological plasma levels of atrial natriuretic peptide (ANP) actually involve sodium excretion in spontaneously hypertensive rats (SHR), we examined the in vivo and ex vivo effects of ANP and an endopeptidase inhibitor, thiorphan, on urinary sodium excretion and the elimination rate of ANP. We found the following: 1) The basal plasma ANP level was higher in 16-week-ol...

Atrial natriuretic peptide (ANP) inhibits renal sympathetic nerve activity (RSNA), provided the vagi are intact. Afferents from chemosensitive cardiopulmonary receptors are specifically required. Such receptors produce the Bezold-Jarisch reflex, are prominent on the ventricular epicardium, and are richly supplied with 5-hydroxytryptamine type 3 (5-HT3) receptors. We tested the hypothesis that e...

A new insofar as chronobiologic therapeutic approach by atrial natriuretic peptide (ANP) for hypertension and/or congestive heart failure (CHF) is based on the release of ANP from ANP cDNA transfected Chinese Hamster Ovary (CHO) cells encapsulated in polycaprolactone (PCL) tubes. ANP secretion was maintained for at least 6 months. The encapsulated cells remained viable during culturing. Control...
