Validez de constructo y confiabilidad del “cuestionario para medir la adherencia al tratamiento de los pacientes con enfermedad cardiovascular”

La determinación de la adherencia al tratamiento de los pacientes con enfermedad cardiovascular es indispensable para la planeación de intervenciones que impacten la salud pública. El objetivo de la presente investigación fue determinar la validez de constructo y la confiabilidad del “Cuestionario ...

Effect of green tea as a protective measure against dental erosion in coronary dentine

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate the effect of green tea as a protective measure on eroded dentin. Disks of human coronary dentin were selected based on surface hardness and randomly assigned to 3 groups (n = 10): DW - distilled water, CHX - 0.2% chlorhexidine digluconate, and GT - green te...

Swimming training attenuates oxidative damage and increases enzymatic but not non-enzymatic antioxidant defenses in the rat brain

Braz. j. med. biol. res; 49 (10), 2016
Although it is well known that physical training ameliorates brain oxidative function after injuries by enhancing the levels of neurotrophic factors and oxidative status, there is little evidence addressing the influence of exercise training itself on brain oxidative damage and data is conflicting. This ...

Comparison of totally tubeless percutaneous nephrolithotomy and standard percutaneous nephrolithotomy for kidney stones: a randomized, clinical trial

Braz. j. med. biol. res; 49 (4), 2016
This study aimed to compare the totally tubeless percutaneous nephrolithotomy and standard percutaneous nephrolithotomy techniques regarding their rates of success and complications in patients with kidney stones. Patients were randomly assigned to two groups. Forty-four patients (24 men; mean age: 50.40...

Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats

Braz. j. med. biol. res; 49 (6), 2016
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in ...

Effect of magnesium ion on human osteoblast activity

Braz. j. med. biol. res; 49 (7), 2016
Magnesium, a promising biodegradable metal, has been reported in several studies to increase bone formation. Although there is some information regarding the concentrations of magnesium ions that affect bone remodeling at a cellular level, little is known about the effect of magnesium ions on cell gap ju...

Quercetin alleviates pulmonary angiogenesis in a rat model of hepatopulmonary syndrome

Braz. j. med. biol. res; 49 (7), 2016
Quercetin shows protective effects against hepatopulmonary syndrome (HPS), as demonstrated in a rat model. However, whether these effects involve pulmonary vascular angiogenesis in HPS remains unclear. Therefore, this study aimed to assess the effect of quercetin on pulmonary vascular angiogenesis and ex...

Effect of EDTA on TGF-β1 released from the dentin matrix and its influence on dental pulp stem cell migration

Braz. oral res. (Online); 30 (1), 2016
Abstract: Bioactive molecules stored in dentin, such as transforming growth factor beta1 (TGF-b1), may be involved in the signaling events related to dental tissue repair. The authors conducted an in vitro evaluation of the amount of TGF-b1 released from dentin slices after treatment with 10% ethylenedia...

Antimicrobial activity of different disinfectants against cariogenic microorganisms

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to assess the in vitro antimicrobial effects of chlorhexidine digluconate (CHX), polyhexamethylene biguanide (PHBM), and octenidine dihydrochloride (OCT) on cariogenic microorganisms by using their minimum inhibitory concentration (MIC) and minimum bactericidal concentr...

Validation and Invariance of the Dental Anxiety Scale in a Brazilian sample

Braz. oral res. (Online); 30 (1), 2016
Abstract: The aim of this study was to evaluate the properties of the Dental Anxiety Scale (DAS) when applied to Brazilian adults and to test its invariance across independent samples and different sociodemographic groups. Sociodemographic data, reports on previous unpleasant dental experiences and DAS r...
