The present study was carried out to elucidate the distribution of calcium-independent phospholipase A(2) (iPLA(2)) in the normal monkey brain. iPLA(2) immunoreactivity was observed in structures derived from the telencephalon, including the cerebral neocortex, amygdala, hippocampus, caudate nucleus, putamen, and nucleus accumbens, whereas structures(More)
The present study was carried out, using inhibitors to secretory phospholipase A2 (sPLA2, 12-epi-scalaradial), cytosolic phospholipase A2 (cPLA2, AACOCF3), or calcium-independent phospholipase A2 (iPLA2, bromoenol lactone), to compare possible contributions of central nervous PLA2 isoforms to the development of allodynia after facial carrageenan injection(More)
The fusion of synaptic vesicles with the plasma membrane during exocytosis can be recorded by membrane capacitance measurements under voltage-clamp conditions. These measurements enable high time-resolution quantitation of exocytosis. The present study was carried out using the above technique to elucidate the effects of various polyunsaturated fatty acids(More)
Peroxynitrite (ONOO−) and species derived from it can oxidize and nitrate lipids, proteins and DNA leading to changes in signaling molecules. The present study was carried out to elucidate possible effects of CNS peroxynitrite in a mouse model of orofacial pain. Mice that received facial carrageenan injection + intracerebroventricular (i.c.v.) injection of(More)
Bilateral lesions of the hypothalamic paraventricular nuclei (PVN) induce hyperphagia and obesity, and ghrelin stimulates appetite in rodents and humans. Conversely, corticotrophin-releasing hormone (CRH) and melanotan-II (MT-II, a synthetic structural homologue of alpha-melanocyte-stimulating hormone, alphaMSH) inhibit feeding behavior. The purpose of the(More)
The present study was carried out to elucidate the effect of a single episode of oxidative stress on pyramidal neurons of the rat hippocampus. A significant increase in the number of neurons that were immunolabeled for the toxic lipid peroxidation product, 4-hydroxynonenal (HNE) was observed in field CA3 of the hippocampus, at 1 day, 7 days and 14 days(More)
