The pathological alterations in upper motor neurons were investigated in 27 cases of adult-onset sporadic amyotrophic lateral sclerosis (ALS). No signficant cytoskeletal alterations were found in the Betz cells of any of the cases except one, although cytoskeletal pathology was consistently present in lower motor neurons. The one case had severe(More)
The effects of 3-week treatment with a typical antipsychotic drug chlorpromazine and three atypical antipsychotic drugs (risperidone, olanzapine and perospirone) on the binding to dopamine D2 and serotonin 5-HT2A receptors were examined in the rat stratum and frontal cortex, respectively. Subchronic treatment with chlorpromazine (10 mg/kg) and perospirone(More)
The purpose of this study was to determine whether human parathyroid hormone (h-PTH) enhances trabecular bone mass and connectivities that were reduced by streptozotocin (STZ)-induced diabetes in rats. Seven-month-old female Wistar rats were injected with STZ or its vehicle intraperitoneally. All vehicle-injected normal controls were sacrificed 0, 4, 6, 8,(More)
Background: Several clinical and laboratory studies concerning port-site recurrence have raised the concern that laparoscopic procedures might worsen the prognosis of malignant disease. However, the long-term prognosis of patients with malignancy who undergo laparoscopic surgery is still unknown. The purpose of this study was to examine the long-term(More)
 The complete nucleotide sequence of broad bean wilt virus -2 (BBWV-2) RNA 2 was determined. The sequence is 3593 nucleotides in length, and contains a single open reading frame which has the potential to encode a 119 kDa polyprotein. Direct amino acid sequencing of the virus coat proteins suggests that the polyprotein is processed to produce three(More)
The aim of this study was to investigate the association between daily life activity and risk of developing diabetes. The study population included 2924 Japanese male office workers aged 35 to 59 years who did not have IFG (fasting plasma glucose level 6.1–6.9 mmol/l), Type 2 diabetes (fasting plasma glucose level ≥7.0 mmol/l and/or medication for diabetes)(More)
Although the backpropagation (BP) scheme is widely used as a learning algorithm for multilayered neural networks, the learning speed of the BP algorithm to obtain acceptable errors is unsatisfactory in spite of some improvements such as introduction of a momentum factor and an adaptive learning rate in the weight adjustment. To solve this problem, a fast(More)
Hemiresection-interposition arthroplasty of the distal radioulnar joint has been carried out in 12 men. The indication was osteoarthritis with an intact triangular fibrocartilage, or when the fibrocartilage could be reconstructed. The average age was 41 years and average follow up for 53 months. In all the patients, there was relief of pain and a(More)
Insulin secretion and islet glucose metabolism were compared in pancreatic islets isolated from GK/Wistar (GK) rats with spontaneous Type 2 (non-insulin-dependent) diabetes mellitus and control Wistar rats. Islet insulin content was 24.5±3.1 μU/ng islet DNA in GK rats and 28.8±2.5 μU/ng islet DNA in control rats, with a mean (±SEM) islet DNA content of(More)
Extrarenal Wilms' tumour is rare and its imaging has received scant mention in the literature. We describe a 2-year-old boy with a firm mass in the right flank. CT, MRI and ultrasonography showed an inhomogeneous solid mass located in the retroperitoneum, which was separate from the right kidney. Angiography showed an enlarged right gonadal artery and(More)
