Thyroid hormone receptor alpha gene variants increase the risk of developing obesity and show gene-diet interactions.
Thyroid hormone receptor-beta resistance has been associated with metabolic traits. THRA gene sequencing of an obese woman (index case) who presented as empirical thyroid hormone receptor-α (THRA) resistance, disclosed a polymorphism (rs12939700) in a critical region involved in TRα alternative processing.THRA gene variants were evaluated in three independent europid populations (i) in two population cohorts at baseline (n=3417 and n=2265), 6 years later (n=2139) and (ii) in 4734 high cardiovascular risk subjects (HCVR, PREDIMED trial).The minor allele of the index case polymorphism (rs12939700), despite having a very low frequency (4%), was significantly associated with higher body mass in…
Risk factors differentially associated with non-alcoholic fatty liver disease in males and females with metabolic syndrome.
espanolIntroduccion: el higado graso no alcoholico (HGNA) es una enfermedad hepatica cronica mas prevalente en los paises occidentales. Objetivos: evaluar factores de riesgo asociados a HGNA en hombres y mujeres diagnosticados con SM estratificados segun terciles del indice de esteatosis hepatica (HSI). Metodos: analisis transversal del estudio PREDIMED Plus (incluyendo unicamente informacion del nodo Navarra-Nutricion). Un total de 278 participantes (141 hombres y 137 mujeres) con SM fueron estratificados segun terciles de HSI. El estudio analizo variables clinicas, bioquimicas e informacion sobre el estilo de vida, como grado de adherencia a la dieta mediterranea y practica de actividad f…
Quantum dynamical study of the O(1D) + CH4→ CH3+ OH atmospheric reaction
Time independent quantum mechanical (TIQM) scattering calculations have been carried out for the O((1)D) + CH4(X(1)A1) → CH3(X(2)A2″) + OH(X(2)Π) atmospheric reaction, using an ab initio ground potential energy surface where the CH3 group is described as a pseudo-atom. Total and state-to-state reaction probabilities for a total angular momentum J = 0 have been determined for collision energies up to 0.5 eV. The vibrational and rotational state OH product distributions show no specific behavior. The rate coefficient has been calculated by means of the J-shifting approach in the 10-500 K temperature range and slightly depends on T at ordinary temperatures (as expected for a barrierless reacti…
