Variation in the adhesive protein gene sequences of Mytilus edulis, M. galloprovincialis, and M. trossulus collected in Delaware, Kamaishi (Japan), and Alaska, respectively, was analyzed by the polymerase chain reaction (PCR) using two sets of oligonucleotide primers. The first set, Me 13 and Me 14, was designed to amplify the repetitive region. The length(More)
This study was carried out to clarify the carcinogenic factors associated with nonviral hepatocellular carcinoma (HCC). A total of 320 HCC patients diagnosed and treated from January 2000 to December 2006 were enrolled. The clinical characteristics of non-B non-C HCC patients were examined to determine possible carcinogenic factors. Of 320 HCC patients, 64(More)
AIM Regulatory T (Treg) cells may play a pivotal role in the persistence of hepatitis C virus (HCV) infection and the development of hepatocellular carcinoma (HCC). Therefore, we examined their frequency in peripheral blood from patients with HCV-positive chronic hepatitis (CH), cirrhosis (LC) and HCC. METHODS Treg cells were identified as CD4(+), CD25(+)(More)
Of 10 epileptic children with IgA deficiency, one showed normal IgA synthesis and secretion on in vitro pokeweed mitogen (PWM) stimulated lymphocyte culture in contrast to IgA deficiency in vivo, two showed IgA synthesis in cytoplasm without any release of IgA into the supernatant and seven failed to synthesize IgA. Co-cultures with allogeneic T or B cells(More)
BACKGROUND C-reactive protein (CRP) is used as a biomarker of ulcerative colitis (UC) activity, but CRP levels are sometimes insufficient to reflect UC activity. Therefore, a simple noninvasive biomarker assay with sufficient sensitivity and specificity to accurately reflect UC activity is desired. Since prostaglandin E2 production and colonic inflammation(More)
The current study was carried out with particular emphasis on the association between phonetic function tests and alterations in the appearance of the hypopharyngeal and laryngeal mucosa, such as capillary dilatation, edema, and vocal fold injection after alcohol intake. The results demonstrated the occurrence of previously unrecognized pathophysiological(More)
BACKGROUND AND STUDY AIMS Polypoid lesions of the gallbladder can be diagnosed by transabdominal ultrasonography and endoscopic ultrasonography. However, the image resolution is limited, and the histopathology of these lesions is difficult to determine. We report here on our preliminary results in four patients using a high-frequency (20 MHz) ultrasonic(More)
Pancreaticoduodenectomy is the standard care for invasive ampullary adenocarcinomas. However, endoscopic snare papillectomy (ESP) might play a curative role in very selected patients. We studied a series of 15 patients with T1 ampullary adenocarcinoma who were treated by ESP alone and followed up for a mean of 29.6 ± 21.9 months (range 8 - 81 months). ESP(More)
Torasemide is a new loop diuretic that combines the effects of furosemide and spironolactone. There are no reports on the effects of torasemide in cats and dogs. This study compared the diuretic effects of furosemide and torasemide in cats and dogs. Cats with pressure overload cardiac hypertrophy were given oral placebo, torasemide 0.3 mg/kg, or furosemide(More)
