Fucoidans have been extensively studied for their various biological activities but the exact role of fucoidans on the inflammatory processes associated with arthritic disease has not been studied. The effect of the treatment of high, medium and low molecular weight fucoidans (HMWF, MMWF and LMWF, respectively) on the progression of collagen-induced(More)
This study examined the bioactivity of yeast (Saccharomyces cerevisiae)-fermented aged black garlic (FBG) on obese mice supplied a high-fat diet (HFD) and its in vitro antioxidant activity. Aged black garlic (BG) exhibits potent antioxidative effects and has been subjected to extensive research. In addition, the bioactivity of some natural products is(More)
NADPH, a major reducing power in microorganisms, is mostly generated from the pentose phosphate (PP) pathway by glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) expressed by the zwf and gnd genes, respectively. The characteristics of these two genes in Escherichia coli were compared after their re-introduction into the(More)
Low molecular weight fucoidan (LMWF) is widely used to treat metabolic disorders, but its physiologic effects have not been well determined. In the present study, we investigated the metabolic effects of LMWF in obese diabetic mice (leptin receptor-deficient db/db mice) and the underlying molecular mechanisms involved in endoplasmic reticulum (ER)(More)
PURPOSE The purpose of this study was to compare the degree of cognitive level, nutritional status and depression in elderly according to living situations. METHOD The subjects consisted of 173 elderly classifying three groups(living alone, living with spouse, living with children). Data was collected from March to June, 2003 by a structured questionnaire(More)
Two PHA synthase phaC1 and phaC2 genes cloned from the new strain Pseudomonas putida KCTC1639 were metabolically engineered for the overproduction of medium-chain-length polyhydroxyalkanoate (mcl-PHA). The overexpressed phaC1 and phaC2 genes in P. putida KCTC1639 were compared in terms of the biosynthesis of mcl-PHA, fatty acid assimilation, distribution of(More)
Oral health affects older adults and their quality of life. Oral care is reported to have a low priority in nursing care of older adults, and repeated assessments to detect oral health problems are seldom performed. The purpose of this study was to investigate the relationships among level of oral health, nutrition, and oral health-related quality of life(More)
A cloned tktA gene encoding transketolase (TK), the most critical enzyme in the nonoxidative pentose phosphate (PP) pathway, was reinforced into the parent Escherichia coli for metabolic flux control of carbohydrate. It was also transformed into the transformant E. coli harboring phbCAB operon for the odd-ball biosynthesis of PHB. The biosynthesis of PHB(More)
Wogonin is a plant monoflavonoid which has been reported to inhibit cell growth and/or induce apoptosis in various tumors. Herein, we investigated the in vitro and in vivo anticancer effects and associated mechanisms of wogonin in human breast cancer. Effects of wogonin were examined in estrogen receptor (ER)-positive and -negative human breast cancer cells(More)
Z39Ig is a transmembrane protein containing two Ig homology domains with unknown functions. Immunohistochemical analyses of human carotid atherosclerotic plaques detected Z39Ig staining in areas rich in foamy macrophages. Z39Ig staining was also observed in macrophages in the lining layers and sublining areas of rheumatoid arthritis synovium. Z39Ig staining(More)
