BACKGROUND It is controversial as to whether nicorandil would have cardioprotective effects in patients with acute myocardial infarction (AMI) who are undergoing reperfusion therapy. A meta-analysis was performed to study the impacts of nicorandil on functional outcomes after AMI. METHODS AND RESULTS Randomized prospective cohort or retrospective cohort(More)
BACKGROUND/AIMS Histological typing of gastric cancer is important for determining the treatment strategy and predicting the prognosis. We compared the histological types obtained by endoscopic forceps biopsy with the finally determined histological types of surgically resected specimens to investigate the reliability of histologically typing gastric cancer(More)
BACKGROUND Low-dose dobutamine stress echocardiography (DSE) assesses myocardial viability at the early stage of acute myocardial infarction (AMI), but its assessment is subjective and variable. Automated function image (AFI) determines global longitudinal peak strain (GLPS) based on tissue tracking technique. The ability of GLPS obtained by AFI during(More)
Although diarrhea or constipation is the most common symptom in the digestive tract disorders, the pathophysiology is very difficult to make out clear. Particularly, the main subject of this symposium, chronic diarrhea develops commonly recurring diarrhea condition over a period of months or years, and requires many tests and much effort to diagnose it. And(More)
The first step in the formation of bile acids is 7uhydroxylation of cholesterol. Subsequently 7ahydroxycholest-4-en-3-one is formed, which is a common precursor of the two primary bile acids, cholic acid and chenodeoxycholic acid. 5,BCholestane-3~t , 7a -d io l , a p recursor of chenodeoxycholic acid is formed from the A4-3-keto intermediate by a pathway(More)

We treated two patients with a ruptured amebic liver abscess. The diagnosis was made at a relatively early stage and treatment was successful for one patient, but an accurate diagnosis of liver abscess was not made and invasive extraintestinal amebiasis led to multiple organ failure and to death for the other. Neither patient had been outside of Japan, and(More)
Although several investigators have reported serum α-fetoprotein positive gastric cancer with or without metastasis to the liver, its site of production is still unclear. We studied on the site of α-fetoprotein synthesis in our cases which showed remarkably high level of serum α-fetoprotein, and clarified the presence of αfetoprotein producing gastric(More)
A p-i-n organic photovoltaic cell with tetrabenzoporphyrin (BP), a BP-C₆₀ dyad and PCBM for the p-, i- and n-layers, respectively, gave a better fill factor and power conversion efficiency than the corresponding p-i-n cell having a 1:1 blend film of BP and PCBM as the i-layer.
