Functional polymorphisms in the CYP3A4, CYP3A5, and CYP21A2 genes in the risk for hypertension in pregnancy

An intronic single nucleotide polymorphism (SNP) in the CYP3A5 gene (CYP3A5*3; SNP rs776746) affects RNA splicing and enzymatic activity. The CYP3A5*3 frequency increased with distance from the equator and natural selection has been proposed to explain the worldwide distribution of this allele. CYP3A activity has been related with the risk for hypertension in pregnancy, a major cause of morbidity and mortality among women, and CYP3A5*3 could reduce the risk for this disease in populations from regions with high sodium and water availability. The CYP3A5 genotype was related with blood pressure in the general population, but the effect on the risk for hypertension in pregnancy has not been evaluated. We compared the allele and genotype frequencies of three functional SNPs in the CYP3A5 (rs776746), CYP3A4 (rs2740574), and CYP21A2 (rs6471) genes between pregnant women who developed hypertension (n=250) or who remained normotensive (control group, n=250). In addition, we sequenced the full CYP3A5 coding sequence in 40 women from the two groups to determine whether some gene variants could explain the risk for hypertensive pregnancies in our population. Allele and genotype frequencies did not differ between hypertensive and normotensive women for the three CYP variants. We did not find CYP3A5 nucleotide changes that could explain a higher risk for hypertension in pregnancy. Our data suggests that the variation in CYP3A5, CYP3A4, and CYP21A2 did not contribute to the risk for hypertension in pregnancy in our populationThe author´s work is supported by a grant from the Spanish Fondo de Investigaciones Sanitarias/Fondos FEDER European Union (ETS PI08/90008)

De la impotencia al poder-no. Tópicos de la resistencia en la cultura iberoamericana

La pujante presencia de Iberoamérica en el ámbito geopolítico, así como en la literatura y las artes a nivel global, es indiscutible en nuestros días. A partir de ello, cobra vigencia analizar ciertos tópicos culturales de la demarcación. El marco teórico posestructuralista añade grandes posibilidades reflexivas al escrutinio investigativo. Gilles Deleuze y Félix Guattari, junto con Giorgio Agamben son los principales pensadores que introducen los ejes paradigmáticos de los estudios aquí reunidos, los cuales son producto de la colaboración internacional entre académicos de la Universidad Autónoma del Estado de México y la Universidad Pontificia Bolivariana de Medellín, Colombia, a través de la Red de investigación “Crítica a las manifestaciones del poder: violencia y resistencia”.Universidad Autónoma del Estado de Méxic

Functional polymorphisms in genes of the Angiotensin and Serotonin systems and risk of hypertrophic cardiomyopathy: AT1R as a potential modifier

<p>Abstract</p> <p>Background</p> <p>Angiotensin and serotonin have been identified as inducers of cardiac hypertrophy. DNA polymorphisms at the genes encoding components of the angiotensin and serotonin systems have been associated with the risk of developing cardiovascular diseases, including left ventricular hypertrophy (LVH).</p> <p>Methods</p> <p>We genotyped five polymorphisms of the <it>AGT</it>, <it>ACE</it>, <it>AT1R</it>, <it>5-HT2A</it>, and <it>5-HTT </it>genes in 245 patients with Hypertrophic Cardiomyopathy (HCM; 205 without an identified sarcomeric gene mutation), in 145 patients with LVH secondary to hypertension, and 300 healthy controls.</p> <p>Results</p> <p>We found a significantly higher frequency of <it>AT1R </it>1166 C carriers (CC+AC) among the HCM patients without sarcomeric mutations compared to controls (p = 0.015; OR = 1.56; 95%CI = 1.09-2.23). The <it>AT1R </it>1166 C was also more frequent among patients who had at least one affected relative, compared to sporadic cases. This allele was also associated with higher left ventricular wall thickness in both, HCM patients with and without sarcomeric mutations.</p> <p>Conclusions</p> <p>The 1166 C <it>AT1R </it>allele could be a risk factor for cardiac hypertrophy in patients without sarcomeric mutations. Other variants at the <it>AGT</it>, <it>ACE</it>, <it>5-HT2A </it>and <it>5-HTT </it>did not contribute to the risk of cardiac hypertrophy.</p

How can the dermocosmetics brand la roche-posay recruit new consumers using digital channels?

The dermocosmetic brand LaRoche-Posay has recently lost a position in the sector to a competitor. The purpose of this work project is to understand the digital behavior of consumers in the dermocosmetic sector and evaluate how effective is La Roche-Posay’s digital strategy in addressing these consumers. From a primary research, we infer there are two segments of consumers, thatcan be distinguished by their involvement with skin care. The recommendation for the brand lies in targeting the involved segment of consumers, according to their digital behavior, who have great sales potential but aren’t currently well impacted by the brand
