Evaluation of the health status of preschool children stratified based on the weight-length index (WLI).

This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.

Genetic characterization of two S-adenosylmethionine-induced ABC transporters reveals their roles in modulations of secondary metabolism and sporulation in Streptomyces coelicolor M145.

S-Adenosylmethionine (SAM) was previously documented to activate secondary metabolism in a variety of Streptomyces spp. and to promote actinorhodin (ACT) and undecylprodigiosin (RED) in Streptomyces coelicolor. The SAM-induced proteins in S.

Assessment of reference values for hair minerals of Korean preschool children.

Hair samples of 655 children (3-6 yr of age) from metropolitan and small cities in Korea were analyzed to determine the content of 23 minor and trace elements with the aim of assessing reference values. Fifteen essential elements (Fe, Zn, Cu, Ca, Mg, Mn, P, Na, K, Cr, Se, Li, V, Co, Mo) and 8 harmful elements (Pb, Al, Hg, As, Cd, Ba, Bi, U) were taken into account. Measurements were performed by inductively coupled plasma-mass spectrometry.

Empirically derived major dietary patterns and their associations with overweight in Korean preschool children.

Prevailing dietary patterns and their association with nutritional outcomes are poorly understood, particularly for children in Korea. Our purposes were to identify major dietary patterns and to examine their associations with overweight among young children in Korea. For 1441 preschool children, usual diet was assessed by a FFQ, from which thirty-three food groups were created and entered into a factor analysis.

Dietary trans-10, cis-12 and cis-9,trans-11 conjugated linoleic acids induce apoptosis in the colonic mucosa of rats treated with 1,2-dimethylhydrazine.

We have previously shown that a diet containing a mixture of conjugated linoleic acid (CLA) isomers reduces the incidence of colon tumors in rats treated with 1,2-dimethylhydrazine (DMH). The present study examined which of the two main CLA isomers, trans-10,cis-12 CLA (t10c12) or cis-9,trans-11 CLA (c9t11), decreases colon tumor numbers and the mechanisms for this effect. Six-week-old, male Sprague-Dawley rats were intramuscularly injected with 15 mg/kg of DMH twice per week for 6 weeks and fed a control diet, 1% t10c12, or 1% c9t11 for 30 weeks.

Accumulation of S-adenosylmethionine induced oligopeptide transporters including BldK to regulate differentiation events in Streptomyces coelicolor M145.

S-Adenosylmethionine (SAM), the major methyl donor in diverse biological processes, was recently found to be involved in the regulation of differentiation in streptomycetes. Exogenous SAM, in a quantity as low as 2muM, enhanced antibiotic production and inhibited morphological development of Streptomyces coelicolor M145. Total protein profiling of S.

Effect of conjugated linoleic acid isomers on insulin resistance and mRNA levels of genes regulating energy metabolism in high-fat-fed rats.

Objective: We investigated the effects of specific conjugated linoleic acid (CLA) isomers on glucose metabolism and insulin resistance and on mRNA levels of genes important in glucose and lipid metabolism.

Methods: Sprague-Dawley rats were fed for 8 wk on a high-fat diet (45% kcal from fat) or one of three CLA-supplemented diets (1% CLA) containing differing isomers of CLA, including a mixture of CLAs (CLA mix), cis-9, trans-11-CLA (C9,T11-CLA), or trans-10, cis-12-CLA (T10,C12-CLA).

Results: Compared with the high-fat group, all the CLA groups had enhanced glucose tolerance.

trans-10, cis-12 conjugated linoleic acid reduces insulin-like growth factor-II secretion in HT-29 human colon cancer cells.

We previously demonstrated that a mixture of conjugated linoleic acid (CLA) isomers decreases colon cancer incidence in rats treated with 1,2-dimethylhydrazine. Our in vitro studies have also shown that CLA inhibits the growth of HT-29 cells, a human colon cancer cell line. When we compared the individual potencies of the two main isomers found in the mixture of CLA isomers (e.

Dietary supplementation of conjugated linoleic acid reduces colon tumor incidence in DMH-treated rats by increasing apoptosis with modulation of biomarkers.

Objectives: We investigated the effects of conjugated linoleic acid (CLA) on tumor incidence, apoptosis, eicosanoid formation, 1,2-diacylglycerol (DAG), and fatty acid profiles of colonic mucosa in 1,2-dimethylhydrazine-treated rats fed different types of dietary fats.

Methods: One hundred twenty male 7-wk-old Sprague-Dawley rats were assigned to a beef tallow (BT) diet or a fish oil (FO) diet; each group was further divided into two groups, one with CLA supplementation (BTC and FOC) and the other without (BT and FO). All groups were fed for 30 wk on experimental diets that contained 12% (w/w) dietary fat (including 1% CLA for the BTC and FOC groups) and were intramuscularly injected with 1,2-dimethylhydrazine for 6 wk, for a total dose of 180 mg/kg of body weight.

Conjugated linoleic acid (CLA) inhibits growth of Caco-2 colon cancer cells: possible mediation by oleamide.

We have previously observed that dietary conjugated linoleic acid (CLA) inhibited colon tumorigenesis induced by 1,2-dimethylhydrazine in rats. The present study was performed to determine the mechanisms by which CLA inhibits colon cancer cell growth. CLA markedly inhibited Caco-2 cell growth, while linoleic acid (LA) slightly increased growth.
