ABSTRACT BACKGROUND: The interaction between serum lipids and C virus infection is well known, as are serum lipid levels in the Peg-IFN / RBV-based treatment. However, with direct action antivirals (DAAs) this behavior is still unclear. OBJECTIVE: To compare serum lipids levels between patients treated with Peg-IFN/RBV and DAAs and to evaluate lipids in sustained virological response (SVR) with DAAs. METHODS: Retro prospective study comparing the behavior of total cholesterol (TC), low-density lipoprotein ( ...

Abstract Diamond-like carbon (DLC) film is a biocompatible hard coating material that can prevent the leaching of metal ions. This study evaluates the structural characteristics of DLC, with and without silver nanoparticles, deposited by plasma (PECVD) on titanium alloy (Ti-6Al-4V) and bone formation in contact with DLC films. Sixty Ti-6Al-4V samples were used divided in: uncoated, coated with DLC and coated with DLC-Ag. After structural characterization, samples were fixed bilaterally at the rabbit' ...

Analisamos como a populacao negra e a Africa sao representadas nos livros didaticos de Geografia. Nessas obras constatamos poucas referencias e mencoes sobre a populacao negra, quase sempre retratada por meio de estereotipos.

Este artigo propone hacer una discusión acerca de las categorias de género, raza,espacio y poder en la realidad de las relaciones sociales. El poder se manifiesta tanto de manera visible como de manera invisible dependiendo de las estratégias del grupo que lo detiene, y en nombre del poder político, econômico y cultural. La segregación espacial a la cual algunos grupos son submetidos es un reflejo de la predominancia de privilegios de una clase dominante a lo largo de la formación social brasileña. ...

Real-time ultrasound information taken on beef heifers prior to backgrounding is used to develop a logit model to aid heifer retention decisions. The value of ultrasound data is calculated as the difference in certainty equivalents between a decision rule incorporating ultrasound information and one using only visual cues. The value of ultrasound data is found to be around $10 per head but is influenced by heifer value and backgrounding costs.

The loosening or fracture of the prosthetic abutment screw is the most frequently reported complication in implant dentistry. Thin diamond-like carbon (DLC) films offer a low friction coefficient and high wear resistance, functioning as a solid lubricant to prevent the weakening of the implant–abutment system. This study evaluated the effects of DLC nanofilms on the reverse torque of prosthetic abutments after simulated chewing. Abutments with 8° and 11° taper connections, with and without DLC or ...

Mucoepidermoid carcinoma (MEC) is the most common primary salivary malignancy comprised of mucinous, intermediate (clear-cell), and squamoid tumor cells. Intraosseous MECs are rare; however, our study presents a case of a 45-year-old female with an 8-year follow-up. The patient was diagnosed with an intermediate-grade MEC in the mandibular alveolar ridge and was submitted to partial mandibulectomy as treatment. An area of the base of the tongue and floor of the mouth were also included in the surgery ...
