Varied causative and risk factors can lead to cardiac dysfunction. Cardiac dysfunction often evolves into heart failure by cardiac remodeling due to autonomic nervous system disturbance and neurohumoral abnormalities, even if the detriment factors are removed. Renal sympathetic nerve activity plays a pivotal regulatory role in neurohumoral mechanisms. The(More)
Role of peroxynitrite in [3H] gamma-aminobutyric acid (GABA) release evoked by N-methyl-D-aspartate (NMDA) and S-nitroso-N-acetyl-penicillamine (SNAP) and mechanisms of [3H]GABA release induced by peroxynitrite in comparison with those induced by NMDA and SNAP were investigated using cerebrocortical neurons. NMDA dose dependently increased [3H]GABA release,(More)
Functional roles of peroxynitrite in N-methyl-D-aspartate (NMDA)- and sodium nitroprusside (SNP)-evoked releases of acetylcholine (ACh) from cerebral cortical neurons in primary culture have been investigated. NMDA increased the release of ACh in a dose-dependent manner, which was significantly suppressed by(More)
The effect of hydroxyl radical scavengers on acetylcholine (ACh) release evoked by nitric oxide (NO) generators and N-methyl-D-aspartate (NMDA) was investigated. Dimethylthiourea enhanced dose-dependently NO generators-evoked ACh release. Similarly, uric acid and mannitol significantly facilitated ACh release evoked by NO generators. The NMDA-induced ACh(More)
Short-range interaction among the spins can not only results in the rich phase diagram but also brings about fascinating phenomenon both in the contexts of quantum computing and information. In this paper, we investigate the quantum correlation of the system coupled to a surrounding environment with short-range anisotropic interaction. It is shown that the(More)
Peroxynitrite is a product produced by spontaneous reaction of nitric oxide (NO) with superoxide. Functional roles of peroxynitrite in the release of endogenous acetylcholine evoked by NO generators has been examined using primary-cultured cerebral cortical neurons. NO generators, such as sodium nitroprusside and S-nitroso-N-acetylpenicillamine,(More)
We examined changes in expression of the candidate plasticity-related gene 15 (CPG15) in the dentate gyrus (DG) and hippocampal CA3 region in the pentylenetetrazole (PTZ) kindling model and investigated the role of this gene in the phenomenon of mossy fiber sprouting (MFS). Experimental rats were divided into the control and PTZ groups. The epileptic model(More)
