The aim was to assess the relationship between RM consumption and the prevalence or incidence of the Met S and its components in a Mediterranean
population at high risk of cardiovascular disease. Methods and results: Cross-sectional analyses were carried out at baseline and at 1-year follow-up and longitudinal analysis were conducted in a cohort of individuals at high risk of cardiovascular disease from the PREDIMED study. A 137-item validated semi-quantitative food frequency questionnaire, anthropometric measurements, blood pressure, fasting plasma glucose and lipid profile were evaluated both at baseline and after 1-year follow-up. The MetS was defined in accordance with the updated ATP III criteria.
Subjects in the upper quartile of RM consumption were more likely to meet the criteria for the MetS at baseline (OR, 2.3; 95% CI, 1.4-3.9; P-trend=0.001) and after this website 1-year
follow-up (OR, 2.2; 95% CI, 1.3-3.7; P-trend=0.034) compared with those in the quartile of reference, even after adjusting for potential confounders.
The longitudinal analyses showed that individuals in the fourth quartile of RM consumption had an increased risk of MetS (OR, 2.7; 95% CI, 1.1-6.8; P-trend=0.009) or central obesity incidence (OR, 8.1; 95% CI, 1.4-46.0; P-trend=0.077) at the end of the follow-up compared to the lowest quartile.
Conclusions: Higher find more RM consumption is associated with a significantly higher prevalence and incidence of MetS and central obesity in individuals at high risk of cardiovascular disease. (C) 2010 Elsevier B.V. All rights reserved.”
“This work examines the quality factors (Q factors) of resonance associated with the axial and transverse vibrations of single-wall carbon nanotube (SWCNT) resonators through the use of molecular dynamics (MD) simulation. Specifically, the work investigates
the effect of device length, diameter, and chirality, as well as temperature, on the resonant frequency and quality factor of these devices and benchmarks the results of MD simulations against classical theories of energy dissipation. The quality factor (Q) associated with transverse vibration is found to increase with increasing device length (Q similar to L-theta, where 0.8 www.selleckchem.com/products/p5091-p005091.html < theta < 1.4) and decrease with increasing device diameter (Q similar to D-mu, where 1.4 < mu < 1.6), while the Q associated with axial vibration is almost independent of length and diameter. We show that to accurately predict temperature dependence of Q, the external and internal energies need to be properly decomposed, and temperature quantum correction should be performed. For both vibrational modes, Q shows a temperature dependence Q similar to T-alpha, where alpha > 1 when below Debye temperature due to quantum effects, and Q gradually recovers the classical T-1 dependence when above Debye temperature. Our temperature dependence is in contrast to prior studies that suggested Q similar to T-beta, where 0 < beta < 1.
