While we have a fair understanding of how and where forelimb-hand manipulative movements are controlled by the neocortex, due to functional imaging studies, we know little about the control of bipedal movements such as walking because of technical difficulties. We succeeded in visualizing cortical activation patterns of human gait by measuring relative(More)
OBJECTIVE To establish an appropriate steroid treatment regimen for autoimmune pancreatitis (AIP). METHODS A retrospective survey of AIP treatment was conducted in 17 centres in Japan. The main outcome measures were rate of remission and relapse. RESULTS Of 563 patients with AIP, 459 (82%) received steroid treatment. The remission rate of(More)
Genetic polymorphisms of UDP-glucuronosyltransferases (UGTs) are involved in individual and ethnic differences in drug metabolism. To reveal co-occurrence of the UGT1A polymorphisms, we first analyzed haplotype structures of the entire UGT1A gene complex using the polymorphisms from 196 Japanese subjects. Based on strong linkage disequilibrium between(More)
To document synaptic interactions between neurons in the precentral cortex of macaque monkeys, we recorded in vivo the intracellular (IC) membrane potentials of cortical neurons simultaneously with extracellular (EC) action potentials of neighboring cells. The synaptic potentials correlated with EC spikes were obtained by spike-triggered averages (STA) of(More)
1. We examined single-neuronal activity in the temporal pole of monkeys, including the anterior ventromedial temporal (VMT) cortex (the temporopolar cortex, area 36, area 35, and the entorhinal cortex) and the anterior inferotemporal (IT) cortex, during a visual recognition memory task. In the task, a trial began when the monkey pressed a lever. After a(More)
BACKGROUND To compare the efficacy and toxicity of three platinum-based combination regimens against cisplatin plus irinotecan (IP) in patients with untreated advanced non-small-cell lung cancer (NSCLC) by a non-inferiority design. PATIENTS AND METHODS A total of 602 patients were randomly assigned to one of four regimens: cisplatin 80 mg/m(2) on day 1(More)
Identification of familiar people is essential in our social life. We can identify familiar people by hearing their voices as well as by viewing their faces. By measuring regional cerebral blood flow (rCBF) by positron emission tomography (PET), we identified neural substrates for the recognition of familiar voices. The brain activity during discrimination(More)
BACKGROUND Liver fibrosis is the main predictor of the progression of nonalcoholic fatty liver disease. Transient elastography (FibroScan), which measures liver stiffness, is a novel, noninvasive method to assess liver fibrosis. AIM We investigated the usefulness of liver stiffness measurement in the evaluation of liver fibrosis in nonalcoholic fatty(More)
1. Using iontophoretic techniques, we investigated the influence of dopamine (DA) antagonists [haloperidol (HAL), a non-selective DA antagonist; sulpiride (SUL), a selective antagonist for D2 receptors; and fluphenazine (FLU), a potent antagonist for D1 receptors] on neuronal activity related to a delayed response (DR) task in the monkey prefrontal cortex(More)
