BACKGROUND The changes in nonalcoholic fatty liver disease (NAFLD) range over a wide spectrum, extending from steatosis to steatohepatitis (NASH). However, it has remained difficult to differentiate between NASH and nonprogressive NAFLD by clinical examination. We investigated the interrelationships between serum high-sensitivity C-reactive protein (hs-CRP)(More)
The acrosome reaction is a membrane fusion event that is prerequisite for sperm penetration through the zona pellucida. To elucidate the molecular mechanisms involved in membrane fusion, the expression and localization of Rab proteins, a subfamily of small GTPases that have been shown to play key roles in regulation of intracellular membrane traffic and(More)
AIM To identify the predictive factors for the presence of small bowel lesions in patients with obscure gastrointestinal bleeding (OGIB). METHODS A total of 242 patients with OGIB (overt 149: occult 93) were retrospectively included in the present study. Capsule endoscopy (CE) was carried out to investigate the small bowel, and detected lesions were(More)
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver injury in many countries. Genetic factors are important for the development of NAFLD, as well as environmental factors. Recently an angiotensin II type 1 receptor (AGTR1) has been recognized as important in the aetiology of fibrosis in the liver. (More)
Tektins are composed of a family of filament-forming proteins associated with ciliary and flagellar microtubules. A new member of the TEKTIN gene family, which was designated as rat Tektin4, was obtained by PCR technique combined with yeast two-hybrid screening. Rat Tektin4 cDNA consists of 1,341 bp encoding a 52 kDa protein of 447 amino acids. Tektin4(More)
Tight junctions (TJs) create a paracellular permeability barrier to restrict the passage of ions, small solutes, and water. Ameloblasts are enamel-forming cells that sequentially differentiate into preameloblasts, secretory, transition, and ruffle-ended and smooth-ended maturation ameloblasts (RAs and SAs). TJs are located at the proximal and distal ends of(More)
BACKGROUND Evidence regarding the association between alcohol consumption and the gastro-esophageal reflux disease (GERD) spectrum has been conflicting. We examined the association between alcohol consumption and erosive esophagitis and Barrett's epithelium in Japanese men. METHODS The study population comprised 463 men subjects who had undergone an upper(More)
Tektins are composed of a family of filament-forming proteins localized in cilia and flagella. Four types of mammalian Tektins have been reported, and at least two types of Tektins, Tektin2 and Tektin4, have been verified to be present in sperm flagella. A new member of the TEKTIN gene family, which was designated as rat Tektin5, was obtained by PCR(More)
Claudins are integral membrane proteins at tight junctions (TJs) and form TJ strands. In the present study, we found that claudin-7 was localized along the entire lateral membranes of epididymal epithelium, including the apical junctional region throughout the epididymis, but claudin-8 was restricted to the apical junctional region. This finding raises the(More)
BACKGROUND/AIMS The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument. METHODS This was a two-way crossover study conducted over 6(More)
