Phosphoinositide-specific phospholipase C (PLC) is a key enzyme in signal transduction. It was previously demonstrated that an antibody to an isozyme of PLC, PLC-delta, produces intense staining of neurofibrillary tangles (NFT), the neurites surrounding senile plaque (SP) cores and neuropil threads in the brains of patients with Alzheimer's disease (AD).(More)
We examined protein kinase C (PKC) activity in Ca2+-dependent PKC (Ca2+-dependent PKC activities) and Ca2+-independent PKC (Ca2+-independent PKC activities) assay conditions in brains from Alzheimer's disease (AD) patients and age-matched controls. In cytosolic and membranous fractions, Ca2+-dependent and Ca2+-independent PKC activities were significantly(More)
The present article focuses on our studies on the metabolism of the inositol phospholipids in Alzheimer disease (AD). The phospholipase C (PLC) isozyme, PLC-delta 1, was abnormally accumulated in neurofibrillary tangles (NFT), the neurites surrounding senile plaque cores, and neuropil threads in AD brains. Anti-PLC-delta 1 antibody marked the same(More)
Introduction. The incidence of endometriosis affecting skin tissue represents only 0.5-1.0% of all endometriosis cases. A malignancy in the abdominal wall arising from endometriosis following cesarean section is even rarer; only 21 cases have previously been reported. The therapeutic strategy has not been determined because of the limited cases. We report a(More)
Phosphoinositide-specific phospholipase C (PLC) is a key enzyme in signal transduction. We have previously demonstrated that an antibody to an isozyme of PLC, PLC-delta, produced intense staining of neurofibrillary tangles in the brains of patients with Alzheimer's disease. In the present study, we investigated the protein level and activity of this enzyme(More)
The paper proposes a procedure to analyse local patterns of connectivity among people in social networks using the idea of ego-centric network. The ego-centric networks of every nodes are transformed into normalized representation and classified into patterns. The procedure can be applied to large dataset by giving it in SQL code. We applied the procedure(More)
Primary vulvar adenocarcinomas are very rare. We describe the rare case of primary vulvar apocrine adenocarcinoma, a histologically rare subtype of vulvar adenocarcinoma. A 57-year-old Japanese woman presented with an enlarging vulvar mass. A dark-red, hemorrhagic, ulcerated tumor was on the right side of the anterior labial commissure measuring(More)
Endometriosis is defined as the presence of endometrium-like tissues at extrauterine sites, most commonly in the abdominal cavity. Lymph node endometriosis is a rare but clinically important type of endometriosis that can mimic lymph node metastasis of a malignant tumor.

Mollaret's meningitis is a rare disease of unknown etiology, characterized by repeated aseptic meningitis with transient neurological symptoms and quick recovery. The patient, a 16-year-old boy, had episodes of acute encephalitis followed by complete recovery every year from the age of 13 to 16 years. The symptoms at onset were loss of consciousness, a(More)
