One-kidney, one clip (1K1C) hypertension is often associated with an expanded plasma volume and (once the arterial clip is removed) with natriuresis. Blood pressure (BP), atrial and plasma concentrations of atrial natriuretic factor (ANF), hematocrit, and renal glomerular ANF receptors were therefore studied in 1K1C rats and in their normotensive uninephrectomized controls before and after uncl...

A trial natriuretic factor (ANF), a 28-amino acid peptide hormone synthesized and secreted from atrial myocytes, has been suggested to play an important role in the regulation of extracellular fluid volume and arterial pressure. Physiological and pharmacological doses of this peptide have been shown to produce natriuresis and diuresis, vasorelaxation, and inhibition or antagonism or both of imp...

The contribution of alterations in renal hemodynamics to the diuretic and natriuretic actions of atrial natriuretic factor (ANF) was studied in chronically instrumented conscious dogs. Injection of ANF-(99-119), 10 micrograms/kg, had no effect on mean arterial pressure, heart rate, renal blood flow, or calculated renal vascular resistance; However, it increased urine flow rate (86 +/- 20%) and ...

Accessible online at: http://BioMedNet.com/karger Dear Sir, I read with interest the report by Takeichi et al. [1] on the relationship between left atrial function and plasma levels of atrial natriuretic peptide in patients with various types of heart disease. I would like to make three comments. First, the term atrial natriuretic factor (ANF) is preferable to the term atrial natriuretic peptid...

The present study was designed to evaluate the renal response to atrial natriuretic factor (ANF) in young rats developing spontaneous hypertension (SHR) and compare this response to age-matched, normotensive controls (WKY) and adult animals. At 6 weeks of age, intravenous infusion of ANF (0.25 micrograms/kg min) in anesthetized, euvolemic rats produced a significantly larger natriuresis and diu...

Release of atrial natriuretic factor (ANF) following an elevation in heart rate is thought to be mediated primarily by a change in atrial stretch. To evaluate the direct effect of chronotropic stimulation on ANF release, isolated rat left atria were electrically paced (1-9 Hz) at constant resting tension (0.5-4 g), and the amount of immunoreactive ANF (IRANF) released at each frequency and tens...

To study the mechanisms that activate expression of the atrial natriuretic factor (ANF) gene during pressure-induced hypertrophy, we have developed and characterized an in vivo murine model of myocardial cell hypertrophy. We employed microsurgical techniques to produce a stable 35- to 45-mmHg pressure gradient across the thoracic aorta of the mouse that is associated with rapid and transient ex...

Because previous data have suggested a dependence of ganglionic atrial natriuretic factor (ANF) content on preganglionic cholinergic input, we investigated the possibility that the increased neural activity observed in spontaneously hypertensive rats (SHR) may be reflected by ganglionic immunoreactive ANF levels. Four-week-old normotensive SHR had celiac ganglionic immunoreactive ANF values com...

Abstract— In this paper, Recursive least square (RLS) based complex Adaptive notch filter (ANF) using Steiglitz-McBride (SM) method is proposed to suppress the Radio frequency interference (RFI) in very-highspeed digital subscriber line (VDSL) systems. The proposed RLS-SM ANF converges fast and requires less computational complexity than the existing direct form constrained ANF using recursive ...
