Comparing bufuralol 1'-hydroxylase activity among liver microsomes prepared from individuals whose CYP2D6 genotypes had been determined, we found that the activity tended to decrease depending on the number of the CYP2D6*10 allele. Pre-incubation of liver microsomes from individuals homozygous for the CYP2D6*10 allele resulted in a decrease in the enzyme(More)
OBJECTIVE To determine the extent of audiometric correlation with CT findings. METHODS Forty-four patients (82 ears) with surgically confirmed otosclerosis underwent preoperative CT examination. Based on the computed tomography (CT) findings, the ears were classified into five groups as follows: Group A, the group with no pathological CT findings; Group(More)
PURPOSE To explore a more effective treatment for newly diagnosed stage IV, relapsed, or refractory extranodal natural killer/T-cell lymphoma, nasal type (ENKL), we conducted a phase II study of the steroid (dexamethasone), methotrexate, ifosfamide, L-asparaginase, and etoposide (SMILE) regimen. PATIENTS AND METHODS Patients with newly diagnosed stage IV,(More)
BACKGROUND Chronic pain is defined as intractable pain caused by abnormal pain transmission or impairment of the pain control system per se. Alteration of regional cerebral blood flow (rCBF) is known to occur under the presence of pain stimulation. Epidural spinal cord stimulation (SCS) is occasionally effective in relieving the symptom. OBJECTIVE The aim(More)
In this work, we examined structural changes of actin filaments interacting with myosin visualized by quick freeze deep-etch replica electron microscopy (EM) by using a new method of image processing/analysis based on mathematical morphology. In order to quantify the degree of structural changes, two characteristic patterns were extracted from the EM(More)
The route of the cochlear nerve can be imaged using computed tomography (CT) or magnetic resonance imaging (MRI). To gain information about the cochlear nerve, we conducted a trial measuring the width of the cochlear nerve canal (CNC) using CT. When we examined images of the route of the cochlear nerve on MRI, both in ears with congenital sensorineural(More)
In recent years, the development of single-molecule detection techniques has allowed the dynamic properties of biomolecules, which are normally obscured in conventional ensemble measurements, to be measured. One of these single-molecule detection techniques allows the measurement of dissociation and association events of individual molecules to be measured.(More)
UNLABELLED The current study is an investigation of alterations in regional cerebral blood flow (rCBF) distribution in patients with transient hypothyroidism after thyroidectomy. In addition, the effects of thyroxine treatment on rCBF changes were studied. METHODS Noninvasive rCBF measurements using 99mTc-HMPAO SPECT were performed on 24(More)

The biocompatibility of two different titanium alloys, Ti-6Al-4V ELI and Ti-5Al-2, 5Fe, and pure titanium were evaluated. The results were as follows: 1) Titanium alloys were implanted into the dorsal subcutaneous tissues of the Hartley guinea-pig for 12 weeks, immersed in calf serum or in Ringer's solution for 8 weeks. The surface changes of the titanium(More)
Human dihydrodiol dehydrogenase (DD) catalyses the oxidation of trans-dihydrodiols of polycyclic aromatic hydrocarbons and the reduction of several ketone-containing drugs. About 40-fold interindividual difference in DD activities has been noted. Recently, we found that transcriptional factors, hepatocyte nuclear factor (HNF)-1 alpha, HNF-4 alpha and HNF-4(More)
