Elección del mejor antidepresivo en pacientes con cáncer de mama en tratamiento con tamoxifeno: revisión de la evidencia básica y clínica

Rev. méd. Chile; 144 (10), 2016
Tamoxifen (Tmf), is a standard of care for women with estrogen receptor positive (ER+) breast cancer. Endoxifen is a Tmf metabolite generated by cytochrome P450 2D6 (CYP2D6). Antidepressive agents (AD) are often prescribed to women with breast cancer not only for depression, but also for anxiety and hot ...

Paraoxonase 1 (PON1) Q192R genotypes and their interaction with smoking strongly increase atherogenicity and the Framingham risk score

ABSTRACT Objective Paraoxonase 1 (PON1) polymorphisms are associated with an increased susceptibility to cardiovascular disease. PON1 Q192R polymorphism (rs662) partially determine PON1 hydrolytic activity and protect against oxidation of LDL and HDL. This study aimed to delineate the association of PO...

Polymorphisms in methylenetetrahydrofolate reductase and cystathionine beta-synthase in oral cancer - a case-control study in southeastern Brazilians

ABSTRACT INTRODUCTION: Oral squamous cell carcinoma (OSCC) is a serious public health problem, due to its high mortality rate and worldwide rising incidence. OSCC susceptibility is mediated by interactions between genetic and environmental factors. Studies suggest that genetic variants encoding enzymes ...

PAI-1 haplogenotype confers genetic susceptibility for obesity and hypertriglyceridemia in Mexican children.

Invest. clín; 57 (3), 2016
The presence of childhood obesity predisposes to the development of cardio vascular and metabolic diseases, such as coronary artery disease and type 2 diabetes mellitus, in adulthood. The polymorphisms described in PAI-1 gene have been linked with obesity and metabolic syndrome in several populations. Th...

Caliciviruses in hospitalized children, São Luís, Maranhão, 1997-1999: detection of norovirus GII. 12

Braz. j. microbiol; 47 (3), 2016
ABSTRACT Gastroenteritis is one of the most common diseases during childhood, with norovirus (NoV) and sapovirus (SaV) being two of its main causes. This study reports for the first time the incidence of these viruses in hospitalized children with and without gastroenteritis in São Luís, Maranhão. A t...

Effect of plant growth-promoting bacteria on the growth and fructan production of Agave americana L

Braz. j. microbiol; 47 (3), 2016
ABSTRACT The effect of plant growth-promoting bacteria inoculation on plant growth and the sugar content in Agave americana was assessed. The bacterial strains ACO-34A, ACO-40, and ACO-140, isolated from the A. americana rhizosphere, were selected for this study to evaluate their phenotypic and genotypic...

Diversity of group A rotavirus genes detected in the Triângulo Mineiro region, Minas Gerais, Brazil

Braz. j. microbiol; 47 (3), 2016
ABSTRACT Group A rotaviruses are the main causative agent of infantile gastroenteritis. The segmented nature of the viral genome allows reassortment of genome segments, which can generate genetic variants. In this study, we characterized the diversity of the VP7, VP4 (VP8*), VP6, NSP4, and NSP5 genes of ...
