It is well known that chronic ethanol treatment affects the synthesis of RNA and protein in the brain and the maintenance and function of nervous system. The changes in myelination-related genes are most prominent in human alcoholics. Previously, our cDNA microarray study showed altered Proteolipid protein (PLP), a major protein of central myelin. The(More)
Oxidative stress-induced cell death leads to phosphorylation of 14-3-3ζ at serine 58. 14-3-3ζ is detected at significant levels in cerebrospinal fluid after kainic acid (KA)-induced seizures. Here we examined temporal changes in 14-3-3ζ phosphorylation in the hippocampus and amygdala of mice after KA treatment. Mice were killed at 2, 6, 24, or 48 h after KA(More)
Kainic acid (KA) induces hippocampal cell death and astrocyte proliferation. There are reports that sphingosine kinase (SPHK)1 and sphingosine-1- phosphate (S1P) receptor 1 (S1P(1)) signaling axis controls astrocyte proliferation. Here we examined the temporal changes of SPHK1/S1P(1) in mouse hippocampus during KA-induced hippocampal cell death. Mice were(More)
Atlanto-occipital assimilation is one of the most common osseous anomalies observed at the craniocervical junction. Most patients with atlas assimilation show no symptom, but some have neurological problems such as myelopathy that may require surgical treatment. Occipitocervical fusion may be required if atlato-occipital assimilation is accompanied by(More)
OBJECT The aim of this prospective observational study was to assess the incidence and pattern of hypopituitarism after diffuse axonal injury (DAI) and to identify its effect on these patients in terms of functional outcome. METHODS Of 1307 patients with traumatic brain injury treated at the authors' institution between March 2005 and June 2008, 65(More)
In the patients with brain metastasis (BM), it is impossible to determine who will benefit from surgery because of limited survival. In an attempt to identify optimal candidates for brain metastatectomy, we analyzed patients who survived for <3 months after craniotomy for a single BM lesion. Between January 1st, 1997 and July 31st, 2007, 83 patients with a(More)
BACKGROUND The aim of this study is to report the results of pure endoscopic endonasal transsphenoidal surgery (EETSS) for pituitary adenomas (PAs) and to evaluate the efficacy and safety of this procedure. In addition, we tried to determine the predicting factors for progression of PAs. METHODS We reviewed the medical records of 331 consecutive patients(More)
