“Background: Empirically
derived dietary patterns show strong cross-sectional associations with cardiovascular disease (CVD) risk factors in the Multi-Ethnic Study of Atherosclerosis (MESA).
Objective: We investigated associations between dietary patterns and risk of incident CVD in 5316 men and women.
Design: White, black, Hispanic, and Chinese adults aged 45-84 y and free of CVD and diabetes completed food-frequency questionnaires find more at baseline. Dietary patterns were derived by using principal components analysis. Incident CVD events (n = 207) identified over a median of 4.6 y were verified by death certificates and medical records.
Results: The Fats and Processed Meat dietary 17-AAG ic50 pattern was associated with a greater risk (hazard ratio quintile 5 compared with quintile 1: 1.82; 95% CI: 0.99, 3.35), and the Whole Grains and Fruit dietary pattern was associated with a lower risk (0.54; 0.33, 0.91) of CVD after adjustment for demographic and lifestyle confounders. Associations between
CVD and the Whole Grains and Fruit dietary pattern remained strong after adjustment for waist circumference, blood pressure, lipids, or inflammatory markers.
Conclusions: Data from this multiethnic cohort reinforce findings from predominantly white cohorts, ie, that “”healthy”" and “”unhealthy”" dietary patterns empirically exist and that these patterns are important lifestyle
predictors of CVD incidence. Am J Clin Nutr 2009;90:647-54.”
“The influence of organically modified montmorillonate (OMMT) on the curing reversion of natural rubber (NR) and polychloroprene rubber (CR) blend has been demonstrated in this article. Characteristics of the NR/CR/OMMT hybrid composite were undertaken by combining the cure kinetics, thermal stability, and the detection of phase morphology. Akt inhibitor Compared to the neat rubber blend, thermal gravity analysis has shown improved thermal stability results during degradation for the nanofiller filled ones. Differential scanning calorimetry study has offered cure kinetic results; among which blending with NR has lifted the cure activation temperature of CR low toward. Meanwhile, transmission electron microscopy has shown the intercalation and immobilization of OMMT in the CR phase formed a barrier to NR phase. In addition, to discover the reversion source, infrared spectroscopy has been applied to trace the oxygenic function units in the neat NR vulcanizate. All of the experimental results and related analysis has offered us the base to explain the improvement of the anti-reversion of the rubber blends. (C) 2010 Wiley Periodicals, Inc.
