BACKGROUND Myocardial ischemia-reperfusion represents a clinically relevant problem associated with thrombolysis, angioplasty and coronary bypass surgery. Injury of myocardium due to ischemia-reperfusion includes cardiac contractile dysfunction, arrhythmias as well as irreversible myocyte damage. These changes are considered to be the consequence of(More)
OBJECTIVE To report the definitive diagnosis of anti-NMDA receptor (NMDAR) encephalitis in four Japanese women previously diagnosed with "juvenile acute nonherpetic encephalitis" of unclear etiology, and to describe their long-term follow-up in the absence of tumor resection. METHODS We extensively reviewed the case histories with current clinical and(More)
Tacrolimus is a macrolide lactone with potent immunosuppressive properties. It has been shown in clinical studies to prevent allograft rejection. The pharmacokinetics of tacrolimus in healthy subjects and transplant patients has been described in earlier studies using immunoassay methods; however, detailed information on the absorption, distribution,(More)
Tyrosine 3-hydroxylase (TH, EC 1.14.16.2) catalyzes the first and rate-limiting step of the catecholamine biosynthetic pathway in the nervous and endocrine systems. The TH locus was disrupted in mouse embryonic stem cells by homologous recombination. Mice heterozygous for the TH mutation were apparently normal. In these mice, TH activity in the embryos and(More)
In order to elucidate roles of the 2'-O-methylation of pyrimidine nucleotide residues of tRNAs, conformations of 2'-O-methyluridylyl(3'----5')uridine (UmpU), 2'-O-methyluridine 3'-monophosphate (Ump), and 2'-O-methyluridine (Um) in 2H2O solution were analyzed by one- and two-dimensional proton NMR spectroscopy and compared with those of related nucleotides(More)
We administered angiotensin II (Ang II) receptor type 1 (AT1) blockade (losartan, 40 mg x kg-1 x d-1), type II receptor (AT2) blockade (PD123319, 100 mg x kg-1 x d-1), or angiotensin-converting enzyme (ACE) inhibitor (enalapril, 30 mg x kg-1 x d-1) to spontaneously hypertensive rats (SHR) from 10 to 20 weeks of age. Control SHR and Wister-Kyoto rats (WKY)(More)
To characterize the metabolic pathway of FK506 (tacrolimus), FK506 or its 31-O-desmethyl metabolite was incubated with liver microsomes prepared from dexamethasone-treated rats in the presence of a NADPH-generating system under aerobic conditions. Besides the four oxidized metabolites already reported, four new metabolites were isolated and identified by(More)
We examined the role of dietary electrolytes and humoral factors in causing seasonal changes in blood pressure. Normal subjects had no seasonal difference in blood pressure, although urinary sodium and norepinephrine were significantly higher in winter than in summer. In patients with essential hypertension blood pressure, urinary sodium and norepinephrine(More)
Human T-cell leukemia virus type-I (HTLV-I) is the etiologic agent of adult T-cell leukemia (ATL). This study examined the status of the oncogenic transcription factor AP-1 in leukemic cells freshly isolated from patients with ATL. Leukemic cells from peripheral blood of all patients with ATL exhibited constitutive AP-1 DNA binding activity, whereas(More)
