Parkinson's disease (PD), one of the most common human neurodegenerative diseases, is characterized by the loss of dopaminergic neurons in the substantia nigra of the midbrain. PD is a complex disorder with multiple genetic and environmental factors influencing disease risk. To identify susceptible genes for sporadic PD, we performed case-control(More)
Corticotropin-releasing hormone (CRH)-containing neurons in the hypothalamic paraventricular nucleus (PVN) are known to be activated during physical or psychological stress, and play an important role as one of the central activators of integrated stress response. Physical exercise has also been suggested as one of the stressors activating CRH neurons in(More)
In this study, we evaluated whether hepatic steatosis affects the viral response to interferon (IFN) and ribavirin combination therapy in Japanese patients with chronic hepatitis C (CHC). Eighty CHC patients treated with IFN alpha-2b and ribavirin for 24 weeks were evaluated retrospectively. Liver biopsy specimens were assessed histopathologically, and(More)
A genetic association between the fibroblast growth factor 20 (FGF20) gene and Parkinson's disease has been found by the pedigree disequilibrium test. This association, however, was not replicated by a case-control association study. In order to clarify the association between the FGF20 gene and Parkinson's disease, we attempted to replicate this(More)
Bacterial translocation occurs after thermal injury in association with intestinal barrier loss. Recently, we found that sensitization of Kupffer cells involved gut-derived endotoxin; therefore, the purpose of this work was to study the mechanisms of sensitization of Kupffer cells in burn injury. Rats received a 30% body surface area full-thickness steam(More)
Agonists of peroxisome proliferator-activated receptor (PPAR)-gamma have been shown to reduce tumor necrosis factor-alpha (TNF-alpha)-induced insulin resistance. On the other hand, sensitization of Kupffer cells to lipopolysaccharide (LPS) and their production of TNF-alpha are critical for progression of alcoholic liver injury. This study was intended to(More)
In alcoholic liver disease, ethanol-induced damage to sinusoidal endothelial cells (SECs) appears to be important in the progression of liver damage. However, little is known about the mechanisms responsible for protection of SECs against ethanol-induced injury. To elucidate the role of sphingosine 1-phosphate (S1P), which is stored in platelets and may be(More)
Maladaptive plasticity at corticostriatal synapses plays an important role in the development of levodopa-induced dyskinesia. Recently, it has been shown that synaptic plasticity is closely linked to morphologic changes of dendritic spines. To evaluate morphologic changes of dendritic spines of two types of striatal medium spiny neurons, which project to(More)
BACKGROUND Penetration of the GI tract by a fish bone was treated by laparotomy. DBE is a useful procedure for removal of a foreign body from the small bowel. CASE REPORT A 33-year-old male presented with bothersome postprandial fullness. He was diagnosed previously with functional dyspepsia, and had been treated with medication for 8 months with no(More)
The effects of combined exposure to ozone and cigarette smoke on airway responsiveness and tracheal vascular permeability, compared with those of single exposure were examined in guinea pigs. Airway responsiveness was assessed by measuring the specific airway resistance (sRaw) as a function of increasing concentration of inhaled methacholine aerosol(More)
