Results: Multivariate multinomial logistic regressions show that childhood problem behaviors, adolescent family

involvement, and dropping out of high school differentiated trajectory membership. Analyses comparing the trajectory groups on behavioral, social, and health outcomes at age 42 revealed that for both men and women, those in the persistent trajectory had the most problems, and those Doramapimod cost in the early adult decliner group also had specific problems. Male late starters also had poor outcomes.

Conclusions: The findings point to the value of identifying specific patterns of substance use over the life course and understanding the differences in their correlates and consequences. The implications of these findings are discussed. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“Background: Choline is an essential nutrient for humans, and part of this requirement is met by endogenous synthesis catalyzed by hepatic phosphatidylethanolamine N-methyltransferase

(PEMT). PEMT activity is difficult to estimate in humans because it requires a liver biopsy. Previously, we showed that mice that lack functional PEMT have dramatically reduced concentrations of docosahexaenoic acid (DHA; 22:6n-3) in plasma and of liver phosphatidylcholine (PtdCho)-a phospholipid formed by PEMT.

Objective: The objective was to evaluate plasma Ricolinostat ic50 PtdCho-DHA concentrations as a noninvasive marker of liver PEMT activity in humans.

Design: Plasma PtdCho-DHA concentrations were measured in 72 humans before and after they consumed a low-choline diet, and correlations were analyzed in relation to estrogen status, PEMT polymorphism rs12325817, the ratio of plasma S-adenosylmethionine (AdoMet) to S-adenosylhomocysteine (AdoHcy), and dietary choline intake; all of these factors are associated with changes in liver PEMT activity. PtdCho-DHA and PEMT activity were also measured in human liver specimens.

Results: At baseline, the portion of PtdCho species containing DHA (pmol PtdCho-DHA/nmol PtdCho) was higher in premenopausal women than in men

and postmenopausal women (P < 0.01). This ratio was lower in premenopausal women with the rs12325817 polymorphism in the PEMT gene (P < 0.05), and PtdCho-DHA concentration and PEMT activity were lower in human liver selleck products samples from women who were homozygous for PEMT rs12325817 (P < 0.05). The ratio of DHA-PtdCho to PtdCho in plasma was directly correlated with the ratio of AdoMet to AdoHcy (P = 0.0001). The portion of PtdCho species containing DHA in plasma was altered in subjects who consumed a low-choline diet.

Conclusion: PtdCho-DHA may be useful as a surrogate marker for in vivo hepatic PEMT activity in humans. This trial was registered at clinicaltrials.gov as NCT00065546. Am J Clin Nutr 2011;93:968-74.”
