A double-quadratic model for predicting Vibrio species in water environments of Japan.

Vibrio spp. are natural inhabitants of marine and estuarine environments. Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus are the major infectious agents for humans.

The Development of a Novel, Validated, Rapid and Simple Method for the Detection of Sarcocystis fayeri in Horse Meat in the Sanitary Control Setting.

Sarcocystis fayeri (S. fayeri) is a newly identified causative agent of foodborne disease that is associated with the consumption of raw horse meat. The testing methods prescribed by the Ministry of Health, Labour and Welfare of Japan are time consuming and require the use of expensive equipment and a high level of technical expertise.

Defining the Genome Features of Escherichia albertii, an Emerging Enteropathogen Closely Related to Escherichia coli.

Escherichia albertii is a recently recognized close relative of Escherichia coli. This emerging enteropathogen possesses a type III secretion system (T3SS) encoded by the locus of enterocyte effacement, similar to enteropathogenic and enterohemorrhagic E. coli (EPEC and EHEC).

[Control of toxicity of Sarcocystis fayeri in horsemeat by freezing treatment and prevention of food poisoning caused by raw consumption of horsemeat].

More than 27 outbreaks per year of food poisoning caused by consuming horse meat were reported in Kumamoto Prefecture (including Kumamoto City) from January 2009 to September 2011. It was found that the causative agent of the outbreaks was a protein with a molecular weight of 15 kDa that had originated from bradyzoites of Sarcocystis fayeri parasitizing the horse meat. Rabit ileal loop tests showed that pepsin treatment of homogenates of frozen horse meat containing the cysts of S.

Human gastroenteritis outbreak associated with Escherichia albertii, Japan.

Although Escherichia albertii is an emerging intestinal pathogen, it has been associated only with sporadic human infections. In this study, we determined that a human gastroenteritis outbreak at a restaurant in Japan had E. albertii as the major causative agent.

Human serum albumin-thioredoxin fusion protein with long blood retention property is effective in suppressing lung injury.

Thioredoxin (Trx) is a redox-active protein with anti-inflammatory effects but with a short half life of 1 h. Genetic fusion of Trx to human serum albumin (HSA) extended its half life without causing significant loss of its biological activities. HSA-Trx caused a decrease in the number of cells in brochoalveolar lavage fluid, the wet/dry ratio and the inflammation at the respiratory tract of the ovalbumin (OVA) induced lung injury model mouse.

Spontaneously Ruptured Giant Splenic Cyst with Elevated Serum Levels of CA 19-9, CA 125 and Carcinoembryonic Antigen.

Splenic cyst is a relatively rare disease; however, the occurrence of complications associated with its rupture is even more rare. A 20-year-old female patient who had severe abdominal and left shoulder pain was admitted to our hospital. The patient's abdomen was hard and tender to the touch and she presented with a high fever.

Albumin fusion of thioredoxin--the production and evaluation of its biological activity for potential therapeutic applications.

Thioredoxin-1 (Trx) is a redox-active protein with anti-inflammatory effects. The effect of albumin fusion on the pharmacokinetic and pharmacodynamic properties of Trx was evaluated in this study. The findings indicate that the properties of human serum albumin and the fusion protein are comparable.

Expression of MUC1 recognized by a monoclonal antibody MY.1E12 is a useful biomarker for tumor aggressiveness of carcinoma of the gallbladder.

The overall outcome of gallbladder carcinoma has not been favorable because of frequent recurrence at distant sites after surgery. A high-level expression of MUC1 recognized by a monoclonal antibody (mAb), MY.1E12, is correlated with poor survival in several types of carcinomas.

Expression of UDP-N-acetyl-alpha-D-galactosamine-polypeptide N-acetylgalactosaminyltransferase isozyme 3 in the subserosal layer correlates with postsurgical survival of pathological tumor stage 2 carcinoma of the gallbladder.

Purpose And Experimental Design: Little is known about the molecular events leading to the development and progression of pathological tumor stage 2 (pT(2)) gallbladder carcinoma. An alteration in the site of O-glycosylation may be associated with malignant behavior of carcinoma cells by modulation of the biological properties of the target mucin. The UDP-N-acetyl-alpha-D-galactosamine-polypeptide N-acetylgalactosaminyltransferase isozyme 3 (GalNAc-T3) has the epithelial gland-specific expression and catalyzes mucin-type O-glycosylation.

Aorsin, a novel serine proteinase with trypsin-like specificity at acidic pH.

A proteinase that hydrolyses clupeine and salmine at acidic pH, called aorsin, was found in the fungus Aspergillus oryzae. Purified aorsin also hydrolysed benzyloxycarbonyl-Arg-Arg-4-methylcoumaryl-7-amide optimally at pH 4.0.

Long-term results after cholecystectomy alone for patients with pancreaticobiliary maljunction without bile duct dilatation.

A pancreaticobiliary maljunction (PB-MJ) without bile duct dilatation is relatively rare. The standard treatment for these patients remains controversial. In this study, we followed up the patients with PB-MJ without bile duct dilatation who mainly underwent a cholecystectomy alone.

Analysis of microsatellite instability, K-ras gene mutation and p53 protein overexpression in intrahepatic cholangiocarcinoma.

Background/aims: Genetic alterations are considered to play an important role in both the carcinogenesis and biological behavior of human malignancies. However, the clinical implications of intrahepatic cholangiocarcinoma are poorly understood. We investigated the microsatellite instability, K-ras gene mutations and p53 protein overexpression and their correlation with clinicopathological features to elucidate the clinical implications of genetic alterations in intrahepatic cholangiocarcinoma.

Expression of cyclooxygenase-2 in the subserosal layer correlates with postsurgical prognosis of pathological tumor stage 2 carcinoma of the gallbladder.

Postsurgical recurrence at distant sites frequently occurs in pathological tumor stage 2 (pT(2)) carcinoma of the gallbladder even though the carcinoma is limited to the gallbladder wall. Little is known, however, about the molecular events leading to its development and progression. A large body of evidence suggests that cyclooxygenase-2 (COX-2) is up-regulated in carcinoma tissues and plays roles in promoting cell-proliferation, growth and metastasis of carcinoma cells.
