OBJECTIVE The main objective of this study was to evaluate the wear characteristics of fiber-reinforced dental composites. Variables under investigation include the fiber weight percent added to the matrix as well as fiber length. METHODS Dental specimens with glass fiber content of 2, 5.1, 5.7, and 7.6 wt% with fiber length of either 1.5 or 3 mm, were prepared by mixing an activated dental r...

OBJECTIVES In this study is investigated if bundling of two scanners leads to better accuracy in recording faces than a standard face-scanning device. MATERIAL AND METHODS In a group of 28 volunteers, two test specimens were attached to their faces: one on their forehead and one turned 90° on their cheek. Each volunteer was scanned by FaceScan3D® and two bundled Artec EVA® scanners. The scans...

Methods 300 patients were evaluated at 36 months, with a diagnosis of contact dermatitis. All of them underwent delayed skin test reading (patch test), with Brazilian Standard Battery of 30 substances. The test steps (placing two readings and grading of positive responses) were performed according to the standards established by the Brazilian Study Group of Contact Dermatitis (BSGCD) and the In...

The present study aimed to evaluate antimicrobial activity of tigecydcline against 84 multidrug resistant (MDR) Acinetobacter spp. strains by disc diffusion and E-test methods. The results of disc diffusion test were compared according to two different interpretation ways. In addition, E-test results and the disc diffusion results that interpreted by both the methods were checked for compatibil...

Many of the functions required for formation of the imaginal discs of Drosophila melanogaster larvae, from which adult structures are derived, are disc-specific and not required for formation of other larval tissues. Mutants blocked in disc-specific functions can produce mature viable larvae, indicating that larval development is not dependent on concomitant disc development. Some of the mutant...

A 25-year-old Nepali man presented with a 20-day history of fever associated with a lower backache. Physical examination found tenderness over the lower lumbar vertebrae. Magnetic resonance imaging following intravenous contrast injection showed enhancement of the L4 and L5 vertebrae, particularly pronounced around the intervening disc, and areas of endplate erosion. Extra-vertebral enhancement...
