We performed fMRI on the human parieto-occipital cortex in order to identify the neural processing regions of stereopsis. Visual stimulation for stereopsis was performed with a random-dot stereogram displayed in the image guides of a new binocular visual stimulation device that we developed. Interestingly, regions from the dorsal portion of the occipital(More)
We studied the effects of grape seed proanthocyanidins extract (GSPE) given as a ratio of 3 mg in 100 g in a standard diet, on the tibial bone diaphysis in low-calcium fed rats. Measurements of bone density, mineral content, geometry, and bone strength using peripheral quantitative computed tomography (pQCT). Further, the whole tibia bones were tested for(More)
We earlier showed that intestinal STC-1 cells can respond to five basic taste stimuli. Here, we investigated which receptors or channels are involved in the sensing of umami in STC-1 cells. T1R family and metabotropic glutamate receptors were not involved. In contrast, we found that N-Methyl-D-aspartate (NMDA) receptors are expressed in STC-1 cells by(More)
We investigated the effects of grape seed proanthocyanidins extract (GSPE) on bone formation by examining total and cortical bone mass, density, architecture, and strength non-invasively using mandibular condyles of Ca-restricted rats. Forty Wistar male rats, each 5 weeks old, were divided into control (C), low-Ca diet (LCaD), low-Ca diet-standard diet(More)
Short periods of breath-holding (BH) occur frequently during various kinds of sports activities. Increased minute oxygen uptake (V O 2), increased minute carbon dioxide output (V CO 2) and increased minute ventilation (VE) are some of the typical responses just after breaking the BH and resuming breathing and these parameters return to their steady levels(More)
The morphology and immunohistochemistry of inducible nitric oxide synthase (iNOS) and nuclear factor-kappa B (NF-kappa B) were studied on the spiral and vestibular ganglion of young and old ddy mice. The significant decrease in the number of the spiral ganglion cells and a significant expression of iNOS and NF-kappa B were observed in old mice. In contrast,(More)
Ultrastructural and enzyme-cytochemical studies were performed on the Golgi apparatus in secretory cells of the lateral prostate of normal adult rats using serial ultra-thin sections. In the trans-Golgi area, a unique membrane complex composed of tubular portions and cisternal portions showing a rigid appearance is found. This corresponds to the GERL(More)
Following the induction of cold injury in the parietal cortex of rats, the brain extracellular fluid dynamics under conditions of cryogenic edema were investigated morphologically from the aspect of extracellular fluid (ECF)-cerebrospinal fluid (CSF) communication using horseradish peroxidase (HRP) injected into the cisterna magna as a marker. About 24 h(More)
