The renal vasculature functions as an efficient low-pass filter of the multiple frequencies contained within renal sympathetic nerve activity. This study examined the effect of angiotensin II on the frequency response of the renal vasculature. Physio

Background— The renal vasoconstrictor response to renal nerve stimulation is greater in congestive heart failure (CHF) rats than in control rats. This study tested the hypothesis that the enhanced renal vasoconstrictor response to renal nerve stimu

When the renal nerves are stimulated with sinusoidal stimuli over the frequency range 0.04–0.8 Hz, low (≤0.4 Hz)- but not high (≥0.4 Hz)-frequency oscillations appear in renal blood flow (RBF) and are proposed to increase responsiveness of the

The psychometric stability of the Armed Services Vocational Aptitude Battery was studied with data collected at 5 points over a 16-year period using item response theory (IRT) methods. Although 25 of the 200 items changed significantly over the years

To assess the renal functional significance of the pattern of renal sympathetic nerve activation, computer-generated stimulus patterns (delivered at constant integrated voltage) were applied to the decentralized renal sympathetic nerve bundle and ren

Background —Long-term metoprolol therapy improves cardiac performance and decreases mortality in patients with chronic congestive heart failure (CHF). This study examined the effect of long-term metoprolol therapy on renal sodium handling in an exp

To examine the effect of activation of a unique population of renal sympathetic nerve fibers on renal blood flow (RBF) dynamics, anesthetized rats were instrumented with a renal sympathetic nerve activity (RSNA) recording electrode and an electromagn

The effects of physiologic alterations in endogenous angiotensin II activity on basal renal sympathetic nerve activity and its cardiac baroreflex regulation were studied. The effect of angiotensin II type I receptor blockade with intracerebroven- tri

Anatomic and neurophysiological methods were used to identify functionally specific subgroups of renal sympathetic nerve fibers. The distribution of diameters of the predominating unmyelinated fibers showed a major mode at 1.1 microns and a minor mod

Cirrhotic rats (common bile duct ligation; CBDL) have increased efferent renal sympathetic nerve activity (ERSNA), which contributes significantly to the observed renal sodium and water retention and edema formation. Basal ERSNA is increased and fail
