The cytotoxicity of chemotherapeutic agents is attributed to apoptosis. Acquired resistance to the effects of chemotherapy has emerged as a significant impediment to effective cancer therapy. One feature that cytotoxic treatments of cancer have in common is their activation of the transcription factor nuclear factor-kappaB (NF-kappaB), which regulates cell(More)
A 51-year-old man who had a past history of gastric resection for medically uncontrollable gastric ulcer has loss of appetite that recurs periodically. And he has frequently presented spontaneous angina early in the morning since 1984. He was diagnosed as having variant angina by the documentation of typical ST elevation during anginal attack and also by(More)
Peutz-Jeghers syndrome (PJS) is an autosomal-dominant polyposis disorder with an increased risk of multiple cancer. The LKB1/STK11 gene, which acts as a tumor suppressor, is responsible for PJS and plays a role in suppressing breast cancer. The low expression of LKB1/STK11 in sporadic breast cancer is significantly associated with shorter survival. Here we(More)
BACKGROUND/PURPOSE The water jet technique dissects tissue while sparing cord-like structures such as blood vessels. The mechanism of such tissue-selective dissection has been unknown. The novel piezo actuator-driven pulsed water jet (ADPJ) system can achieve dissection with remarkably reduced water consumption compared to the conventional water jet;(More)
The majority of acute cellular rejection occurs in the first few months after liver transplantation. It has been, however, reported that some recipients experience late acute rejection, which occurs more than 3 months after transplantation. We herein report a case of late acute rejection that occurred nearly 10 years after liver transplantation. The patient(More)
BACKGROUND Recently, chronic hepatitis E has been increasingly reported in organ transplant recipients in European countries. In Japan, the prevalence of hepatitis E virus (HEV) infection after transplantation remains unclear, so we conducted a nationwide cross-sectional study to clarify the prevalence of chronic HEV infection in Japanese liver transplant(More)
It has been reported that treatment with branched chain amino acids (BCAAs) increases the survival rates in cirrhotic patients. In this study, we investigated the effect of L-valine, one of BCAAs, on liver fibrosis in rat. To induce liver fibrosis, male Wistar rats were injected carbon tetrachloride (CCl(4)) intraperitoneally (2.0 mL/kg) twice a week for 12(More)
BACKGROUND In living-donor liver transplantation (LDLT), the recipient's portal vein is short. Furthermore, portal vein thrombosis and stenosis can be lethal complications. We had begun the systemic administration of gabexate mesilate, a strong serine protease inhibitor, which has cytoprotective effects of endothelial cells. It is often effective on(More)
BACKGROUND Post-transplant donor-specific anti-HLA antibodies (DSA) reportedly have detrimental effects on the outcomes of organ transplantation. However, the prevalence of post-transplant DSA in the long term after pediatric liver transplantation remains unclear, and the significance of post-transplant DSA is unknown. The aim of this cross-sectional study(More)
BACKGROUND Post-transplant donor-specific HLA antibodies (DSA) may have a detrimental effect on long-term outcomes of organ transplantation. The aim of this study was to specifically evaluate the effect of recipient age on the prevalence of DSA over a long-term follow-up after living donor liver transplantation (LDLT).
