Nucleotide-binding oligomerization domain 1 (NOD1) is an intracellular epithelial cell protein known to play a role in host defense at mucosal surfaces. Here we show that a ligand specific for NOD1, a peptide derived from peptidoglycan, initiates an unexpected signaling pathway in human epithelial cell lines that results in the production of type I IFN.(More)
BACKGROUND & AIMS The mortality rate associated with severe acute pancreatitis (SAP) with necrosis remains high because early prediction of pancreatic necrosis is difficult. We evaluated whether perfusion computerized tomography (CT), which is used to identify early stage ischemia in the brain, could detect ischemic changes in the pancreas in the early(More)
Creutzfeldt-Jakob disease (CJD) is characterized by rapidly progressive dementia with a variety of neurological disorders and a fatal outcome. The authors present a case with visual disturbance as a leading symptom and rapid deterioration in global cognitive functions. The cerebrospinal fluid was positive for 14-3-3 protein, and diffusion-weighted magnetic(More)
OBJECTIVE The objective was to investigate the relationship between prognosis in case of pancreatic cancer and perfusion in tissue surrounding pancreatic cancer using perfusion CT. METHODS We enrolled 17 patients diagnosed with inoperable pancreatic adenocarcinoma. All patients were examined by perfusion CT and then underwent chemotherapy using(More)
Background. In Europe and the United States, it is known that obesity, which is increasing, is closely associated with gastroesophageal reflux disease (GERD), but in Japan no definite consensus has been reached on this relationship. Clarification of the relationship between the two is an important issue. Methods. After screening, gastrointestinal endoscopic(More)
OBJECTIVES Although simultaneous occurrences of autoimmune pancreatitis (AIP) and cancer are occasionally observed, it remains largely unknown whether cancer and AIP occur independently or these disorders are interrelated. The aim of this study was to examine the relationship between AIP and cancer. METHODS We conducted a multicenter, retrospective cohort(More)
Early intensive care for severe acute pancreatitis is essential for improving SAP mortality rates. However, intensive therapies for SAP are often delayed because there is no ideal way to accurately evaluate severity in the early stages. Currently, perfusion CT has been shown useful to predict prognosis of SAP in the early stage. In this presented paper, we(More)
The intracellular sensor NOD1 has important host-defense functions relating to a variety of pathogens. Here, we showed that this molecule also participates in the induction of a noninfectious pancreatitis via its response to commensal organisms. Pancreatitis induced by high-dose cerulein (a cholecystokinin receptor agonist) administration depends on NOD1(More)
OBJECTIVES With the increasing number of living donor liver transplantations, biliary complications in donors have emerged as a major postoperative problem. The aim of the present study was to characterize the features of the biliary complications that occur in donors. METHODS The study subjects comprised 731 consecutive patients who donated liver grafts(More)
