Estudo da expressão de CLIC4 e proteínas associadas em queilites actínicas e carcinomas de células escamosas de lábio inferior

A proteína do canal de cloro intracelular 4 (CLIC4) regula a passagens dos íons de cloro e relaciona-se com a proteína p53, fator de necrose tumoral α (TNF-α), fator de crescimento transformante-β (TGF-β) e com a diferenciação de fibroblastos em miofibroblastos (-SMA) em alguns cânceres huma...

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...

Sleep disorder or simple sleep ontogeny? Tendency for morningness is associated with worse sleep quality in the elderly

Braz. j. med. biol. res; 49 (10), 2016
The objective of this study was to evaluate the alterations in sleep and circadian parameters during the aging process. The study sample comprises volunteers older than 18 up to 90 years of age that answered the Pittsburgh Sleep Quality Index (PSQI) and the Horne and Östberg circadian preference questio...

Multiple facets of HIV-associated renal disease

Braz. j. med. biol. res; 49 (4), 2016
HIV infection has a broad spectrum of renal manifestations. This study examined the clinical and histological manifestations of HIV-associated renal disease, and predictors of renal outcomes. Sixty-one (64% male, mean age 45 years) HIV patients were retrospectively evaluated. Clinical presentation and re...

Cytokine profile and lymphocyte subsets in type 2 diabetes

Braz. j. med. biol. res; 49 (4), 2016
Type 2 diabetes mellitus (T2D) is a metabolic disease with inflammation as an important pathogenic background. However, the pattern of immune cell subsets and the cytokine profile associated with development of T2D are unclear. The objective of this study was to evaluate different components of the immun...

In vitro antibacterial activity of a silicone-based endodontic sealer and two conventional sealers

Braz. oral res. (Online); 30 (1), 2016
Abstract The aim of this study was to evaluate whether the modification in the silver component is capable of providing GuttaFlow 2 with antibacterial activity against Enterococcus faecalis compared with epoxy resin-based (AH Plus) and zinc oxide and eugenol-based (Endofill) sealers. The antibacterial ac...

Moderate sedation helps improve future behavior in pediatric dental patients - a prospective study

Braz. oral res. (Online); 30 (1), 2016
Abstract There is little evidence on the long-term effects of pharmacological management in children undergoing dental treatment. This study aimed to assess children's behavior in consecutive dental sessions following oral rehabilitation using different pharmacological regimens for behavioral control. Pa...

Effect of lectin (ScLL) on fibroblasts stimulated with LPS - an in vitro study

Braz. oral res. (Online); 30 (1), 2016
Abstract: The lectin (ScLL) extracted from the Synadenium carinatum plant has been evaluated as an immunomodulator in diseases such as asthma, neosporosis and leishmaniasis. However, it has not yet been evaluated in the oral cavity. This study evaluated the effect of ScLL on viability, proliferation and ...

The effect of standardised implantoplasty protocol on titanium surface roughness: an in-vitro study

Braz. oral res. (Online); 30 (1), 2016
Abstract: To analyse the changes of surface characteristics of machined and moderately roughened titanium disks following a standardised implantoplasty protocol. Forty titanium discs (machined: n = 20; moderately roughened: n = 20) were instrumented with one half of each disc maintained as the control (n...

Thickness and nanomechanical properties of protective layer formed by TiF4 varnish on enamel after erosion

Braz. oral res. (Online); 30 (1), 2016
Abstract The layer formed by fluoride compounds on tooth surface is important to protect the underlying enamel from erosion. However, there is no investigation into the properties of protective layer formed by NaF and TiF4 varnishes on eroded enamel. This study aimed to evaluate the thickness, topography...
