Glycemic Index, Glycemic Load and Dyslipidemia in Adolescents from Chiapas, Mexico.

Cardiovascular disease risk throughout the life course is increased by abnormal blood lipid levels in youth. The dietary glycemic index (GI) and glycemic load (GL) during adolescence might be related to abnormal blood lipids. This study aimed to analyze the association between dietary GI, GL and dyslipidemia in adolescents from two marginalized regions of Chiapas, Mexico.

Sociodemographic inequalities in cardiovascular risk factors among adolescents from indigenous areas in Chiapas, Mexico.

This study was aimed to determine the prevalence of cardiovascular risk factors among different sociodemographic groups of adolescents from indigenous communities in Chiapas, Mexico. A cross-sectional prevalence study was performed in urban and rural communities in the Tzotzil-Tzeltal and Selva regions of Chiapas. A sample of 253 adolescents was studied, of whom 48% were girls and 52% were boys.

The atypical protein arginine methyltrasferase of Entamoeba histolytica (EhPRMTA) is involved in cell proliferation, heat shock response and in vitro virulence.

Protein arginine methylation regulates several cellular events, including epigenetics, splicing, translation, and stress response, among others. This posttranslational modification is catalyzed by protein arginine methyltransferases (PRMTs), which according to their products are classified from type I to type IV. The type I produces monomethyl arginine and asymmetric dimethyl arginine; in mammalian there are six families of this PRMT type (PRMT1, 2, 3, 4, 6, and 8).

The Tudor Staphylococcal Nuclease Protein of Participates in Transcription Regulation and Stress Response.

is the protozoa parasite responsible of human amoebiasis, disease that causes from 40,000 to 100,000 deaths annually worldwide. However, few are known about the expression regulation of molecules involved in its pathogenicity. Transcription of some virulence-related genes is positively controlled by the cis-regulatory element named URE1.

Identification and functional characterization of lysine methyltransferases of Entamoeba histolytica.

Lysine methylation of histones, a posttranslational modification catalyzed by lysine methyltransferases (HKMTs), plays an important role in the epigenetic regulation of transcription. Lysine methylation of non-histone proteins also impacts the biological function of proteins. Previously it has been shown that lysine methylation of histones of Entamoeba histolytica, the protozoan parasite that infects 50 million people worldwide each year and causing up to 100,000 deaths annually, is implicated in the epigenetic machinery of this microorganism.
