The atrial natriuretic peptide (ANP), a member of the natriuretic peptide family, is a cardiovascular hormone which possesses well defined natriuretic, diuretic, and vasodilating properties. Most of the biological effects of ANP aremediated through its guanylyl cyclase coupled A receptor. Because ANP and its receptors have been shown to be expressed and differentially regulated in the immune sy...
In vitro release of atrial natriuretic peptide (ANP) from atria was examined by ANP radioimmunoassay. Isolated right rat atria were incubated in Krebs-Ringer bicarbonate buffer, and test substances were added to the incubation medium. The fluid was assayed for rat ANP by a radioimmunoassay method recently developed in our laboratory. We produced an antiserum to human ANP(99-216) (alpha-hANP(1-2...
جهت دستیابی به سود و سهم بازار، بسیاری از شرکت ها روش های جدید گوناگونی از قبیل برون سپاری ساخت و ایجاد تنوع در تولید را به کار گرفته اند. این ابداعات در یک محیط پایدار موثر می باشند، ولی می توانند موجب آسیب پذیرتر شدن یک زنجیره تامین نسبت به انواع گوناگونی از اختلالات شوند که از طریق چرخه های اقتصادی غیر قطعی، تقاضا های مصرف کننده و حوادث طبیعی و غیر طبیعی ایجاد می شوند. از این رو مدیریت ریسک ...
OBJECTIVE The first aim of this work was to investigate, under basal conditions in adult male rats, the long-term consequences of perinatal maternal food restriction on the plasma concentrations of vasopressin (VP), aldosterone and atrial natriuretic peptide (ANP) and on plasma renin activity (PRA). Furthermore, under these same conditions, the hypothalamic VP gene expression as well as the den...
Hyperosmolality has been known to increase ANP release. However, its physiological role in the regulation of atrial myocytic ANP release and the mechanism by which hyperosmolality increases ANP release are to be defined. The purpose of the present study was to define these questions. Experiments were performed in perfused beating rabbit atria. Hyperosmolality increased atrial ANP release, cAMP ...
The biological effects of atrial natriuretic peptide (ANP) are mediated by natriuretic peptide receptors (NPRs), which can either activate guanylyl cyclase (NPRA and NPRB) or inhibit adenylyl cyclase (NPRC) to modulate intracellular cGMP or cAMP, respectively. During cardiac development, ANP serves as an early maker of differentiating atrial and ventricular chamber myocardium. As development pr...
Atrial natriuretic peptide (ANP) levels correlate with hyperglycemia in diabetes mellitus, but ANP effects on pancreatic islet β-cell insulin secretion are controversial. ANP was investigated for short- and long-term effects on insulin secretion and mechanisms regulating secretion in isolated rat pancreatic islets. A 3-h incubation with ANP did not affect basal or glucose-stimulated islet insul...
PURPOSE Atrial natriuretic peptide (ANP) has been recently described as an endogenous inhibitor of the synthesis and angiogenic action of vascular endothelial growth factor (VEGF). Given VEGF's key role in promoting neovascularization in proliferative diabetic retinopathy (PDR), this study was designed to evaluate the possibility that ANP could be involved in the neovascular and fibrotic compli...
تحلیلswot ، یکی از مهم ترین ابزارهای تصمیم گیران در فرآیند مدیریت راهبردی است. این ابزار، مدیران را قادر به کشف و شناسایی عوامل داخلی و خارجی مؤثر بر راهبرد سازمان می کند. در نتیجه، این تحلیل ابزار خوبی برای تدوین راهبرد است. تحلیل swot دارای کاستی هایی نیز هست. این تحلیل توانایی ارزیابی وابستگی های موجود در بین عوامل شناسایی شده را ندارد و تنها فهرستی از عوامل و راهبرد ها را به صورت کیفی بیان ...
The balance between vasoconstrictor/sodium-retaining and vasodilator/natriuretic systems is essential for maintaining body fluid and electrolyte homeostasis. Natriuretic peptides, such as atrial natriuretic peptide (ANP), belong to the vasodilator/natriuretic system. ANP is produced by the conversion of pro-ANP into ANP, which is achieved by a proteolytical cleavage executed by corin. In the ki...
