The development of nontoxic but effective radioprotectors is needed because of the increasing risk of human exposure to ionizing radiation. We have reported that α-lipoic acid confers considerable radio-protective effect in mouse tissues when given prior to x-irradiation. In the present study, α-lipoic acid supplementation prior to x-irradiation with 4 and(More)
In this study, we investigated the effects of glycine betaine (GB) on bone marrow death and intestinal damage by gamma rays or carbon ions. C(3)H/He female mice received an i.p.-injection of GB before or after whole-body irradiation with gamma rays or 50 keV microm(-1) carbon ions. The irradiated mice were observed to determine the mortality for 30 days(More)
Sequences of long-interspersed elements (LINE-1, L1) make up ∼17% of the human genome. De novo insertions of retrotransposition-active L1s can result in genetic diseases. It has been recently shown that the homozygous inactivation of two adjacent genes SLCO1B1 and SLCO1B3 encoding organic anion transporting polypeptides OATP1B1 and OATP1B3 causes a benign(More)
A 60-year-old man received interferon/ribavirin combination therapy for chronic hepatitis C in 2002 and achieved sustained virological response. In 2008, a hepatocellular carcinoma (HCC) with a diameter of 60 mm appeared and surgical resection was performed. In March 2011, the patient was referred to our hospital because of portal lymph node swelling.(More)
1 T he indocyanine green (ICG) retention test is widely used for preoperative evaluation of liver function. Individuals who have markedly poor ICG clearance without severe liver diseases are defined as patients with a " constitutional ICG excretory defect. " (1) However, the underlying molecular mechanisms remain unknown. We hypothesized that the ICG(More)
Liver consists of parenchymal hepatocytes and other cells. Liver progenitor cell (LPC) is the origin of both hepatocytes and cholangiocytic cells. The analyses of mechanism regulating differentiation of LPCs into these functional cells are important for liver regenerative therapy using progenitor cells. LPCs in adult livers were found to form cysts with(More)
Alcohol intake leads to the distribution of alcohol and its metabolite, acetaldehyde throughout the blood and organs. Hepatic cirrhosis is associated with abnormal red blood cell morphology and function, particularly impaired red blood cell deformability. To investigate the effect of drinking on red blood cells in patients with hepatic cirrhosis,(More)
BACKGROUND Off-treatment durability of nucleoside analogue (NA) therapy in patients with chronic hepatitis B has not been well investigated. In this study we monitored antiviral effect of NA therapy and evaluated off-treatment durability after NA cessation in patients with chronic hepatitis B. PATIENTS AND METHODS A total of 94 consecutive patients (39(More)
Hepatic stem/progenitor cells in liver development have a high proliferative potential and the ability to differentiate into both hepatocytes and cholangiocytes. In this study, we focused on the cell surface molecules of human induced pluripotent stem (iPS) cell-derived hepatic progenitor-like cells (HPCs) and analyzed how these molecules modulate expansion(More)
European studies have revealed that the ABCB11 c.1331T>C (V444A) polymorphism (rs2287622) C-allele frequency is higher among patients with drug-induced cholestasis. Given the low incidence of this disease, however, this association has not been sufficiently elucidated. We aimed to investigate the significance of this polymorphism in Japanese patients. We(More)
