Haplotypes in CCR5-CCR2 , CCL3 and CCL5 are associated with natural resistance to HIV-1 infection in a Colombian cohort

Biomédica (Bogotá); 37 (2), 2017
RESUMEN Introduction: Variants in genes encoding for HIV-1 co-receptors and their natural ligands have been individually associated to natural resistance to HIV-1 infection. However, the simultaneous presence of these variants has been poorly studied. Objective: To evaluate the association of single a...

Genetic Polymorphism in MMP9 May Be Associated With Anterior Open Bite in Children

Braz. dent. j; 28 (3), 2017
Abstract Anterior open bite (AOB) has a multifactorial etiology caused by the interaction of sucking habits and genetic factors. The aim of this study was to evaluate the association between AOB and polymorphisms in genes that encode Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs). F...

Effectiveness and safety of first-generation protease inhibitors in real-world patients with hepatitis C virus genotype 1 infection in Brazil: a multicenter study

Clinics; 72 (6), 2017
OBJECTIVE: To evaluate the effectiveness and safety of first-generation protease inhibitors for the treatment of genotype 1 hepatitis C virus-infected patients at Brazilian reference centers. METHODS: This multicenter cross-sectional study included hepatitis C virus genotype 1 monoinfected patients trea...

Virological suppression in children and adolescents is not influenced by genotyping, but depends on optimal adherence to antiretroviral therapy

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Objective: To evaluate the virological outcomes in children and adolescents infected with HIV-1 in Salvador, Bahia according to genotyping results. Methods: We retrospectively evaluated the rates of virological suppression of children and adolescents submitted to HIV-1 genotyping test from Jan...

A systematic review of East African-Indian family of Mycobacterium tuberculosis in Brazil

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Introduction: The Mycobacterium tuberculosis East African-Indian (EAI) spoligotyping family (belonging to lineage 1, Indo-Oceanic, defined by the region of deletion RD239) is distributed worldwide, but is more prevalent in Southeast Asia, India, and East Africa. Studies in Latin America have ra...

Geolocalization of HIV-1 subtypes and resistance mutations of patients failing antiretroviral therapy in Salvador - Brazil

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Background: Geographical distribution of HIV variants is an important way to understand the circulation and spread of such viral strains. Objectives: To evaluate the spatial distribution of HIV-1 variants in patients failing antiretroviral therapy, in Salvador, Brazil. Methods: We performed a...

Association between the p53 arginine/arginine homozygous genotype at codon 72 and human papillomavirus E6/E7 mRNA expression

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Objective: To evaluate the association between p53 polymorphisms and human papillomavirus (HPV) E6/E7 mRNA expression. Methods: We analyzed 175 cervical samples from women aged 16-69 years old who were tested for HPV E6/E7 mRNA expression (NucliSENS® EasyQ® HPV). The samples were divided int...

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Background: Dai is a major Chinese ethnic minority group residing in rural areas of the southern part of Yunnan. However, no data exist on the Human Papillomavirus (HPV) prevalence and genotype distribution among Dai women. Method: A total of 793 participants (Dai = 324, Han = 251, other ethni...

Bioethanol strains of Saccharomyces cerevisiae characterised by microsatellite and stress resistance

Braz. j. microbiol; 48 (2), 2017
Abstract Strains of Saccharomyces cerevisiae may display characteristics that are typical of rough-type colonies, made up of cells clustered in pseudohyphal structures and comprised of daughter buds that do not separate from the mother cell post-mitosis. These strains are known to occur frequently in fer...

Screening of melon genotypes for resistance to vegetable leafminer and your phenotypic correlations with colorimetry

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Melon is one of the most important vegetable crops in the world. With short cycle in a system of phased planting, phytosanitary control is compromised, and a great volume of agricultural chemicals is used to control vegetable leafminer. Genetic control is an ideal alternative to avoid the damage...
