The fiber-tracking method enables in vivo visualization of the white matter tracts of the brain using a diffusion tensor MR imaging technique. While this method represents a promising tool in the field of neurosurgery, especially when confronted with brain tumors in eloquent areas, its reliability remains unknown. We present here our preliminary validation(More)
Septins are evolutionarily conserved cytoskeletal GTPases that can form heteropolymer complexes involved in cytokinesis and other cellular processes. We detected expression of the human septin genes Nedd5, H5, Diff6, and hCDC100 in postmortem brain tissues using the reverse transcription-coupled polymerase chain reaction and their products by immunoblot(More)
Gene mutations of Cu/Zn superoxide dismutase (SOD) have been discovered in familial amyotrophic lateral sclerosis (ALS). Oxidative stress also plays a role in the pathogenesis of sporadic ALS. Whether antioxidant therapy is beneficial in this fatal disease is now crucial. We have shown that SOD treatment improves neuromuscular dysfunction and morphological(More)
We have carried out a comparative immunohistochemical study on four members of the septin family, CDCrel-1, Septin6, CDC10, and H5, which are abundantly expressed in the adult mouse brain. We found that each septin showed overlapping but distinct distribution at the levels of light and electron microscopy. CDCrel-1 was abundant in inhibitory presynaptic(More)
We studied trophic effects of angiotensin II, vasopressin, cholecystokinin, and oxytocin on explanted ventral spinal cord cultures from 13- and 14-day-old rat embryos. There was a significant neurite promoting effect of the spinal cord cultures by using angiotensin II, vasopressin, and cholecystokinin. Cholecystokinin had the most potent effect at any(More)
We previously reported that F4/80(+) Kupffer cells are subclassified into CD68(+) Kupffer cells with phagocytic and ROS producing capacity, and CD11b(+) Kupffer cells with cytokine-producing capacity. Carbon tetrachloride (CCl4)-induced hepatic injury is a well-known chemical-induced hepatocyte injury. In the present study, we investigated the immunological(More)
GM3, the simplest ganglioside, modulates cell adhesion, proliferation and differentiation in the central nervous system and exogenously added GM3 regulates cell-cell and cell-extracellular matrix adhesion and induces apoptosis. To assess the anti-tumor action of exogenous GM3, we examined its effect on the proliferation and invasion of glioma cells. Its(More)
We studied trophic effects of angiotensin II, vasopressin and oxytocin on explanted ventral spinal cord cultures from 13-14-old day rat embryos. There was a significant neurite promoting effect in angiotensin II and vasopressin-treated cultures. Angiotensin II had the most potent effect at any concentrations. It became clear that minimum effective(More)
Eight months after radical surgery for small-cell neuroendocrine carcinoma (SCNC) of the urinary bladder, a 69-year-old man was admitted with a brain tumor in the left frontal lobe. The tumor, about 5 cm in diameter, was intensely but heterogeneously enhanced on computed tomography and magnetic resonance imaging. The tumor was subtotally removed, leaving(More)
