Genetic Risk Analysis of Coronary Artery Disease in a Population-based Study in Portugal, Using a Genetic Risk Score of 31 Variants

Arq. bras. cardiol; 111 (1), 2018
Abstract Background: Genetic risk score can quantify individual's predisposition to coronary artery disease; however, its usefulness as an independent risk predictor remains inconclusive. Objective: To evaluate the incremental predictive value of a genetic risk score to traditional risk factors associa...

The rs4430796 SNP of the HNF1β gene associates with type 2 diabetes in older adults

SUMMARY INTRODUCTION: The impact of type 2 diabetes mellitus raises interest in understanding its evolutionary-genetic basis, to unveil yet unknown pathways that may have immediate medical relevance. The HNF1β gene (hepatocyte nuclear factor-1 beta) is a transcription factor expressed in tissues su...

Desempeño de métodos moleculares para la identificación de subtipos poco comunes del virus de la hepatitis C, genotipo 2

Biomédica (Bogotá); 38 (2), 2018
Resumen Introducción. El virus de la hepatitis C (HCV) presenta una gran variabilidad genética, con siete genotipos y numerosos subtipos. La determinación del tipo viral ha sido fundamental para la escogencia y la duración del tratamiento antiviral adecuado. En Venezuela, el genotipo 2 del HCV es r...

Interferon-gamma release assay performance in northeastern Brazil: influence of the IFNG+874 A>T polymorphism

Braz. j. infect. dis; 22 (3), 2018
ABSTRACT Introduction Latent tuberculosis infection diagnosis based on the release of interferon-gamma in cultures of peripheral blood cells stimulated with Mycobacterium tuberculosis antigens has replaced the tuberculin skin test in many countries with low tuberculosis prevalence. The IFN-γ produc...

Clinical and mutational spectrum of Colombian patients with Pelizaeus Merzbacher Disease

Colomb. med; 49 (2), 2018
Abstract Case Presentation: Pelizaeus Merzbacher Disease (PMD) is an X-linked developmental defect of myelination that causes childhood chronic spastic encephalopathy. Its genetic etiology can be either a duplication (or other gene dosage alterations) or a punctual mutation at the PLP1 locus. Clinically...

Braz. j. microbiol; 49 (2), 2018
Abstract Equine influenza is one of the major respiratory infectious diseases in horses. An equine influenza virus outbreak was identified in vaccinated and unvaccinated horses in a veterinary school hospital in São Paulo, SP, Brazil, in September 2015. The twelve equine influenza viruses isolated belon...

PCA3 rs544190G>A and prostate cancer risk in an eastern Chinese population

Int. braz. j. urol; 44 (3), 2018
ABSTRACT Background: The association of prostate cancer antigen 3 (PCA3) polymorphism (SNP, rs544190G>A) with metastatic prostate cancer in European descent has been reported. Our aim of the current study was to re-validate the effect of PCA3 polymorphism on prostate cancer risk in an Eastern Chinese...
