OBJECTIVE Elderly people at nursing homes often suffer from malnutrition, which is characterized by a loss of muscle mass and hypoalbuminemia. This malnourished state is closely associated with an impaired activity of daily living (ADL). We analyzed the nutritional state of such elderly individuals longitudinally over 3 years by anthropometry, serum(More)
BACKGROUND AND OBJECTIVES Genome-wide association studies have revealed a link between autophagy-related (ATG) genes and susceptibility to Crohn's disease. This suggests underlying involvement of autophagy impairment in the pathogenesis of Crohn's disease. This study was performed to investigate the pathophysiological importance of autophagy impairment in(More)
For patients chronically infected with hepatitis C virus (HCV), mutations in the non-structural 5A (NS5A) gene are important predictive factors for the response to interferon (IFN) therapy. In the present study, factor analysis of the therapeutic response of patients following pegylated IFN and ribavirin combination therapy was assessed in a multicenter(More)
BACKGROUND To determine the extent to which hepatic stellate cell (HSC) activation contributes to liver fibrosis, it was found necessary to develop an alternative structural and functional stellate cell marker for in situ studies. Although several HSC markers have been reported, none of those are associated with particular HSC functions. AIM The present(More)
Migration is a fundamental trait in humans and animals. Recent studies investigated the effect of migration on the evolution of cooperation, showing that contingent migration favors cooperation in spatial structures. In those studies, only local migration to immediate neighbors was considered, while long-range migration has not been considered yet, partly(More)
BACKGROUND & AIMS Precisely what type of cells mainly contributes to portal fibrosis, especially in chronic viral hepatitis, such as hepatic stellate cells (HSCs) in the parenchyma or myofibroblasts in the portal area, still remains unclear. It is necessary to clarify the characteristics of cells that contribute to portal fibrosis in order to determine the(More)
BACKGROUND AND AIM Capsule endoscopy (CE) is now widely accepted as a first-line diagnostic modality for obscure gastrointestinal bleeding (OGIB), with a high diagnostic yield compared to other modalities. However, even after negative CE examination, re-bleeding is often known to occur. The aim of the present study was to identify predictive factors of(More)
CYP3A is responsible for approximately 50% of the therapeutic drug-metabolizing activity in the liver. The present study was undertaken to establish the CYP3A4 inducible model for analysis of human drug metabolism using a bioartificial liver composed of the functional hepatocellular carcinoma cell (HCC) line FLC-5. A radial-flow bioreactor (RFB), which is a(More)
Functional intact liver organoid can be reconstructed in a radial-flow bioreactor when human hepatocellular carcinoma (FLC-5), mouse immortalized sinusoidal endothelial M1 (SEC) and A7 (HSC) hepatic stellate cell lines are cocultured. The structural and functional characteristics of the reconstructed organoid closely resemble the in vivo liver situation.(More)
BACKGROUND Transcatheter arterial chemoembolization (TACE) is an effective treatment for hepatocellular carcinoma (HCC) that can cause deterioration of liver function. We aimed to make an early predictive model of long-term liver dysfunction after TACE. METHODS We performed a prospective cohort study involving 109 HCC patients who underwent TACE at Kobe(More)
