Radio Frequency Identification (RFID) is a system that uses radio frequency to transmit identification wirelessly. Its functionality is much more powerful than bar code system, with which a contacting reader must be used to read the bar code. RFID, on the other hand, may read the information stored in a tag with a non-contact reader from a distance as far(More)
Fructosyltransferases catalyze the transfer of a fructose unit from one sucrose/fructan to another and are engaged in the production of fructooligosaccharide/fructan. The enzymes belong to the glycoside hydrolase family 32 (GH32) with a retaining catalytic mechanism. Here we describe the crystal structures of recombinant fructosyltransferase (AjFT) from(More)
BACKGROUND AND AIM The aim of the present study was to elucidate a reasonable model and the efficacy of hepatocellular carcinoma (HCC) screening on an elderly population. METHODS Two-stage HCC screening was conducted in a hepatitis C virus (HCV)-endemic area. First, participants underwent blood tests for hepatitis B surface antigen (HBsAg), anti-HCV(More)
Glycosyltransferases (GTs), which are distributed widely in various organisms, including bacteria, fungi, plants and animals, play a role in synthesizing biological compounds. Glycosyltransferase-1 from Bacillus cereus (BcGT-1), which is capable of transferring glucose to small molecules such as kaempferol and quercetin, has been identified as a member of(More)
Rubredoxin (D.g. Rd) is a small non-heme iron-sulfur protein shown to function as a redox coupling protein from the sulfate reducing bacteria Desulfovibrio gigas. The protein is generally purified from anaerobic bacteria in which it is thought to be involved in electron transfer or exchange processes. Rd transfers an electron to oxygen to form water as part(More)
Branched-chain aminotransferases (BCAT), which utilize pyridoxal 5'-phosphate (PLP) as a cofactor, reversibly catalyze the transfer of the α-amino groups of three of the most hydrophobic branched-chain amino acids (BCAA), leucine, isoleucine, and valine, to α-ketoglutarate to form the respective branched-chain α-keto acids and glutamate. The BCAT from(More)
OBJECTIVE This study compared the characteristic parameters of ocular vestibular-evoked myogenic potential (oVEMP) test between eyes gazing up and eyes closed to evaluate the feasibility of oVEMP test with eyes closed. METHODS Twenty-three healthy adults underwent oVEMP testing with upward gaze and with eyes closed in a randomized order. For each(More)
OBJECTIVES Esophageal squamous cell carcinoma (ESCC) is common in hypopharyngeal squamous cell carcinoma (HSCC) patients. This prospective study is to reveal the prevalence of simultaneous ESCC in newly diagnosed HSCC patients by unsedated transnasal esophagogastroduodenoscopy (EGD) and to analyze the clinical predictors for simultaneous esophageal lesions(More)
Lectins with sugar-binding specificity are widely distributed in higher plants and various other species. The expression of rice lectin from Oryza sativa is up-regulated in the growing coleoptile when anaerobic stress persists. A rice lectin of molecular weight 15.2 kDa has been crystallized using the hanging-drop vapour-diffusion method. From the(More)
