Frequencies of polymorphisms of the Rh, Kell, Kidd, Duffy and Diego systems of Santa Catarina, Southern Brazil

Background Red blood cell genes are highly polymorphic with the distribution of alleles varying between different populations and ethnic groups. The objective of this study was to investigate gene polymorphisms of blood groups in the state of Santa Catarina, Southern Brazil. Methods Three hundred and sev...

Patients with dental calculus have increased saliva and gingival crevicular fluid fetuin-A levels but no association with fetuin-A polymorphisms

Braz. oral res. (Online); 30 (1), 2016
ABSTRACT: Fetuin-A is a potent inhibitor of calcium-phosphate precipitation and of the calcification process, therefore it can also be related with dental calculus. Thus, we aimed to investigate a possible relationship between fetuin-A gene polymorphism and the presence of dental calculus. A possible rel...

MnSOD and GPx1 polymorphism relationship with coronary heart disease risk and severity

Biol. Res; 49 (), 2016
BACKGROUND: Disturbance of the equilibrium between reactive oxygen species (ROS) and anti-oxidants (AOX) has been implicated in various diseases, including atherosclerosis, the most common pathologic process underlying coronary heart disease (CHD). Thus, the defense systems against ROS are critical prote...

The p. N103K mutation of leptin (LEP) gene and severe early onset obesity in Pakistan

Biol. Res; 49 (), 2016
BACKGROUND: Obesity is a complex disorder and has been increasing globally at alarming rates including Pakistan. However, there is scarce research on understanding obesity genetics in Pakistan. Leptin is a hormone secreted by adipocytes in response to satiety and correlates with body weight. Any mutation...

Asociación de polimorfismos del gen factor de necrosis tumoral (TNF) con el desarrollo de reestenosis de stent post angioplastía coronaria

Rev. chil. cardiol; 35 (2), 2016
Introducción: La intervención coronaria percutánea (PCI en inglés) con implante de stent coronario es uno de los procedimientos más utilizados para la revascularización miocárdica en condiciones agudas o crónicas. Múltiples factores se han relacionado con la restenosis de stent, incluyendo aspec...

Apolipoprotein E polymorphism and functional disability in Brazilian elders: the Bambuí Health and Aging Study

Abstract Numerous studies have associated the apolipoprotein E (apoE) ε4 allele with worse health status, but few have assessed the existence of genotype-dependent variations in functional performance. Among participants in the Bambuí Health and Aging Study, Minas Gerais State, Brazil, 1,408 elderl...

Detección del virus del papiloma humano en Corrientes, Argentina: alta prevalencia de genotipo 58 y su filodinámica

Rev. argent. microbiol; 47 (4), 2015
Human papillomavirus (HPV) has the highest mortality rate due to cervical cancer in Northeastern Argentina. The aim of this work was to detect and characterize HPV in samples from the Province of Corrientes, Argentina. HPV detection and typing was performed using PCR-RFLP on samples with different cervic...

Caracterización molecular de aislamientos de Shigella sonnei recuperados en el programa de vigilancia por el laboratorio de la enfermedad diarreica aguda en Colombia

Biomédica (Bogotá); 35 (3), 2015
Introducción. En Colombia, Shigella sonnei es uno de los serotipos más frecuentemente aislados (53,4 %) de muestras clínicas humanas asociadas a la enfermedad diarreica aguda. La identificación de patrones de restricción del ADN mediante electroforesis en gel de campo pulsado constituye la base de l...

Polimorfismo C677T del gen de la metilentetrahidrofolato reductasa en madres de niños afectados con defectos del tubo neural

Invest. clín; 56 (3), 2015
Los defectos del tubo neural (DTN) son las alteraciones congénitas más frecuentes del sistema nervioso central. El mecanismo de transmisión hereditario de los DTN aislados es multifactorial, se debe a la interacción de factores ambientales y genéticos. El polimorfismo 677C>T del gen de la metilentet...

Genetic variants associated with fetal hemoglobin levels show the diverse ethnic origin in Colombian patients with sickle cell anemia

Biomédica (Bogotá); 35 (3), 2015
Introduction: Fetal hemoglobin is an important factor in modulating the severity of sickle cell anemia. Its level in peripheral blood underlies strong genetic determination. Associated loci with increased levels of fetal hemoglobin display population-specific allele frequencies. Objective: We investigate...
