Although several therapeutic options are available for hepatocellular carcinoma (HCC), the outcome is still very poor. One reason is the complexity of signal transduction in the pathogenesis of HCC. The aim of this study was to identify new HCC-related genes and to investigate the functions of these genes in the pathogenesis and progression of HCC. Whole(More)
Objectives: This study aimed to evaluate the efficacy of gemcitabine-based chemoradiotherapy followed by surgery (gem-CRTS) for pancreatic ductal adenocarcinoma (PDAC) for borderline resectable (BR) and locally unresectable (UR) tumors. Methods: One hundred patients with PDAC who underwent the gem-CRTS protocol were classified into 3 groups, namely,(More)
We evaluated clinicopathological factors affecting survival and recurrence after initial hepatectomy in non-B non-C (NBNC) hepatocellular carcinoma (HCC) patients with comparison to hepatitis B or C virus, paying attention to relationship between alcohol consumption and histopathological findings. The medical records on the 201HCC patients who underwent(More)
OBJECTIVES This study aimed to clarify whether pretreatment human equilibrative nucleoside transporter (hENT1) expressions in endoscopic ultrasonography-guided fine-needle aspiration biopsy (EUS-FNAB) specimens obtained from resectable, borderline resectable, and locally advanced unresectable pancreatic ductal adenocarcinoma (PDAC) are concordant with those(More)
UNLABELLED Activated protein C (APC) has cytoprotective effects on liver ischemia-reperfusion injury (IRI). However, it is unclear whether APC is beneficial in steatotic liver IRI. We compared the cytoprotective effects of APC in nonsteatotic and steatotic liver IRI. METHODS Mice fed either normal diets (ND mice) or high fat diets (HF mice), were treated(More)
For pancreatic ductal adenocarcinoma (PDAC) of the head and/or body invading the splenic artery (SA), we developed a new surgical technique of proximal subtotal pancreatectomy with splenic artery and vein resection, so-called pancreaticoduodenectomy with splenic artery resection (PD-SAR). We retrospectively reviewed a total of 84 patients with curative(More)
AIM To evaluate whether the combination of the peripheral blood CD4+ adenosine triphosphate activity (ATP) assay (ImmuKnow assay: IMK assay) and cytochrome P450 3A5 (CYP3A5) genotype assay is useful for monitoring of immunological aspects in the patient followup of more than one year after living donor liver transplantation (LDLT). METHODS Forty-nine(More)
Fungal infections are frequently observed in living-donor liver transplantation (LT) and are correlated with the clinical outcome. Early diagnosis of fungus infection is difficult because of the low positive rate of blood culture and the poor specificity of the (1-3)-D-glucan assay for fungi. A polymerase chain reaction (PCR)-based method was developed for(More)
