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)
We studied the antibody response to various kinds of well-characterized synthetic peptides of human T lymphotropic virus type 1 (HTLV-1) envelope glycoproteins in patients with HTLV-1 associated myelopathy (HAM)/tropical spastic paraparesis (TSP) and non-HAM/TSP HTLV-1 carriers. The serum antibody titers to most of the synthetic peptides were significantly(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)
We quantitated the frequency of B lymphocytes capable of producing antibodies to HTLV-1 in the peripheral blood from patients with HAM/TSP, non-HAM/TSP HTLV-1 carriers and seronegative healthy subjects. Epstein-Barr virus (EBV) was used as a polyclonal activator of B lymphocytes in a limiting dilution condition. We found that B lymphocytes committed to the(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)
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)
