Troglitazone, a new oral antidiabetic drug, is reported to be mostly metabolized to its conjugates and not to be oxidized by cytochrome P-450 (P-450) enzymes. Of fourteen cDNA-expressed human P-450 enzymes examined, CYP1A1, CYP2C8, CYP2C19, and CYP3A4 were active in catalyzing formation of a quinone-type metabolite at a concentration of 10 microM(More)
The primary structure of a novel putative subunit of the mouse glutamate receptor channel, designated as delta 1, has been deduced by cloning and sequencing the cDNA. The delta 1 subunit shows 21-25% amino acid sequence identity with previously characterized rodent glutamate receptor channel subunits and thus may represent a new subfamily of the glutamate(More)
The study examined the association of diabetes mellitus (DM) history with total and common site-specific cancers using a large cohort of 23,378 men and 33,503 women, extracted from 127,477 healthy participants of the JACC Study who were aged 40-79 years and living in 24 municipalities in Japan. At enrollment during 1988-90, each subject completed a(More)
It is suspected that autoimmune disease processes are involved in the pathogenesis of a part of giant cell myocarditis. However, evidence for autoimmunity has rarely been demonstrated in clinical investigations. In this study, we have demonstrated a new animal model of autoimmune myocarditis characterized by the appearance of multinucleated giant cells.(More)
One of the possible causes of dilated cardiomyopathy is considered to be a sequel to myocarditis. Two mechanisms have been proposed in the process of progression of myocarditis into dilated cardiomyopathy: one is a persistent viral infection, and the other is an autoimmune myocardial injury. To clarify the possible part played by the autoimmune mechanism in(More)
OBJECTIVES We examined by thallium-201 scintigraphy whether exercise-induced abnormal blood pressure response (BPR) is related to myocardial ischemia. BACKGROUND Hemodynamic instabilities during exercise in patients with hypertrophic cardiomyopathy (HCM) are considered to be caused by abnormal reflex control of vascular resistance. METHODS In 105(More)
We have previously shown that myelin-associated glycoprotein (MAG) inhibits neurite growth from a neuronal cell line. In this study we show that 60% of axonal growth cones of postnatal day 1 hippocampal neurons collapsed when they encountered polystyrene beads coated with recombinant MAG (rMAG). Such collapse was not observed with denatured rMAG. Neurite(More)
BACKGROUND Familial long-QT syndrome (LQTS) is characterized by prolonged ventricular repolarization. Clinical symptoms include recurrent syncopal attacks, and sudden death may occur due to ventricular tachyarrhythmias. Three genes responsible for this syndrome (KVLQT1, HERG, and SCN5A) have been identified so far. We investigated mutations of these genes(More)
To explore the association between dietary habits and risk of hepatocellular carcinoma (HCC) mortality in Japan, univariate analyses was performed using data from the JACC Study. A cohort of 46,465 males and 64,327 females aged 40 to 79 in 19 prefectures in Japan completed the baseline survey during 1988-1990 and were followed up until the end of 1999. The(More)
