Background: Although the risk of gastric cancer can be stratified according to Helicobacter pylori (H. pylori) IgG antibody titer and pepsinogen levels (ABC classification), a population-based gastric cancer screening system combining serological tests and endoscopy has not been introduced. This study aimed to compare the total testing cost per participant between the ABC classification method and the existing protocol.

However, these findings have not been supported by pathological findings. We aimed to examine the association between the EUS and pathological findings of the same area of the pancreas.

The significantly upregulated and downregulated genes in the IRF2 KO pancreas have been reported. The catalogue of gene transcripts included two types of calcium-binding proteins (S100 calcium binding protein G [S100g] and Annexin A10 [Anxa10]), which were highly upregulated in the IRF2 KO pancreas.

However, effective therapeutic strategies for preventing and treating NASH-mediated liver cirrhosis and HCC are lacking. Cholesterol is closely associated with vascular endothelial growth factor (VEGF), a key factor that promotes HCC.

The pathways of autophagy and endocytosis are closely related, and Rab7 plays crucial roles in both. In this study, we analyzed the function of Rab7 in acute pancreatitis using pancreas-specific Rab7 knockout (Rab7) mice.

Background & Aims: Proliferation, differentiation, and morphogenesis of the intestinal epithelium are tightly regulated by a number of molecular pathways. Coordinated action of intestine is achieved by gastrointestinal hormones, most of which exert these actions through G-protein-coupled receptors. We herein investigated the role of Gα-mediated signaling in intestinal homeostasis.

Aim: We attempted to clarify the difference in the gut environment between mice administrated several experimental diets.
Methods: Male wild-type mice were fed a high-fat (HF) diet, a choline-deficient amino acid-defined (CDAA) diet, and a methionine-choline-deficient (MCD) diet for 8 weeks.
The role of Toll-like receptor (TLR) signaling has attracted much attention in the development of hepatic inflammation and hepatocellular carcinoma (HCC). We herein sought to determine the role of TLRs and responsible cells in steatohepatitis-related HCC. We used hepatocyte-specific Pten-deficient (Pten(Δ) (hep)) mice, which exhibit steatohepatitis followed by liver tumor formation, including HCC.

It has been thought to arise from injury to the global rostral midbrain including the nigrostriatal pathway by a transtentorial pressure gradient. We present a similar patient, but his parkinsonism resisted levodopa administration during the initial therapy.

A 46-year-old female diagnosed with intestinal BD presented with ileocecal perforation and diffuse peritonitis and subsequently underwent ileocolic resection with ileostomy. After surgery, she suffered from refractory para-ileostomal ulceration associated with BD.

Methods: A total of 16 patients with endoscopically proven high-risk GVs treated using combined B-RTO with ET+LPD and EIS with CA between January 2007 and July 2012 were enrolled.
Results: Twelve cases included GVs involving both the cardia and fundus, two cases included fundal varices and two cases included cardiac varices.
We herein report a case of hepatocellular carcinoma (HCC) with lung metastasis that was successfully treated with transcatheter arterial infusion chemotherapy via the hepatic and bronchial arteries. A 64-year-old man diagnosed with HCC in 2003 was treated with locoregional therapy followed by sorafenib for recurrent HCC. Tumor thrombosis and lung metastasis were noted in April 2012.

However, little is known about the clinical presentation of GIST, especially small lesions. The purpose of the present study was to clarify the efficacy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of GIST and to determine its clinical course.

Emerging data have shown a close association between compositional changes in gut microbiota and the development of nonalcoholic fatty liver disease (NAFLD). The change in gut microbiota may alter nutritional absorption and storage. In addition, gut microbiota are a source of Toll-like receptor (TLR) ligands, and their compositional change can also increase the amount of TLR ligands delivered to the liver.

Interferon regulatory factor (IRF) 1 and IRF2 function as a tumor suppressor and oncoprotein, respectively, in several types of cancers. We investigated whether IRF1 and IRF2 are involved in the progression of pancreatic cancer.
