Abstract
We tested the hypothesis that γ-aminobutyric acid (GABA) mediated neurotransmission within the NTS produces an inhibition of the baroreflex response of splanchnic sympathetic nerve discharge (sSND). In urethane-anesthetized, artificially ventilated and vagotomized male SHR and Wistar Kyoto (WKY) ra...

Abstract
We investigated the expression of nerve growth factor (NGF) and its association with cardiac sympathovagal balance in a rodent model of self-limited peritonitis. Male Wistar rats were randomized into the following groups: normal control, sham, gastric perforation (GP), and GP treated with methylpred...

Abstract
We studied whether, in parallel to the activity of the hypothalamus-pituitary-adrenal axis and the sympathetic nervous system, hypothalamic cytokine expression and monoaminergic neurotransmitter concentrations are affected during the development and chronification of arthritis induced by immunizatio...

Abstract
The acceleration plethysmography (APG) is a useful tool to analyze the heart rate variability (HRV) with the merits of being portable and simple in operation. To use it clinically, 'stationarity' of the HRV measurements in resting state should be justified as a fundamental premise. Therefore, the pu...

Abstract
Patients receiving subtypes I and II of L-PANP surgery had less decrease in contraction of bladder than those receiving the same subtype of O-PANP surgery at 10 days post-operation (Z = -2.358, P = 0.018; Z = -2.268, P = 0.033). And no difference was observed in patients receiving subtype III PANP s...

Abstract
In this study the main question investigated was the number and size of both binucleate and mononucleate superior cervical ganglion (SCG) neurons and, whether post-natal development would affect these parameters. Twenty left SCGs from 20 male pacas were used. Four different ages were investigated, t...

Abstract
The sample consisted of 2 unembalmed fresh male human cadavers of a mean age of 83 years. Chondrocytes and synoviocytes were identified at the capsular tissue of each uncovertebral interface from C2-C3-C6-C7. Immunoreactivity for PGP 9.5, SP, CGRP, and NPY was observed at all uncovertebral interface...

The general view of whole vascular casts of the lumbar spinal cord and nerve roots showed a high density of vessels. Bifurcation or anastomoses of capillaries approximately took place at right angles in a T-shaped pattern and capillaries showed a lot of ring-like compressions. This ring-like compres...

The I/I genotype of the UCP2 45 bp insertion/deletion polymorphism was associated with relatively higher blood pressure and HRV sympathetic indices (low frequency percentage and low frequency:high frequency ratio) at supine rest. For the -55C/T polymorphism of UCP3, individuals carrying the -55T all...

Observational studies indicate that abnormal cardiac repolarization and impaired autonomic function, particularly in combination, appear to identify patients with less severe LV dysfunction at risk of SCD. Extensive scarring also appears to identify patients at risk. Ongoing and planned studies will...

Abstract
The activity of the subthalamic nucleus (STN) is intimately related to movement and is generated, in part, by voltage-dependent Na(+) (Na(v)) channels that drive autonomous firing. In order to determine the principles underlying the initiation and propagation of action potentials in STN neurons, 2-p...

We also examined whether there are changes in the concentration of serotonin (5HT) within the raphé nucleus i...

We showed that intracisternal injection of a low dose (1 microg/kg) of the 5-HT(1A) receptor agonist, 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT), significantly reduced the increases in heart rate and renal sympathetic nerve activity evoked by disinhibition of the DMH, but had no effect on th...

Abstract
We conclude that NPY exerts excitatory effects on sympathetic tone, but inhibits responses evoked by somatic inputs. We speculate that this apparent contradiction may be due to differential expression of NPY receptor subtypes on the soma of sympathetic premotor neurons in the RVLM and on the presyna...

We tested this hypothesis using sequen...

In the treatment of rectal cancer, various attempts have been made to reduce the local recurrence rate. In Japan, lateral node dissection (LND) has been widely performed as a standard procedure for lower rectal cancers. Studies since the 1980s have shown that LND reduces the local recurrence rate an...

Stimulation of the sensory branch of the pudendal nerve elicits vasodilatation of the vagina. The likely mechanism is via activation of spinal pathways that in turn activate pelvic nerve efferents to produced changes in vaginal blood flow.
