1. Effect of denture cleansers on Candida species biofilms formed on the surface of differents materiais used in dentures base / Efeito de limpadores quimicos sobre biofilmes de Candida formados sobre a superficie de materiais para base de proteses removiveis
Candida denture biofilm is considered the the primary aetiological agent for the development of oral candidosis, which is the most common fungal oral infection in humans. Although, for patients with limited motor capacity, chemical cleansing with immersion in denture cleansers has been shown to be effective in controlling Candida biofilm accumulation, limite

2. Formação de biofilme bacteriano sobre polimetilmetacrilato usado como cimento ósseo / Formation of bacterial biofilm on polymethylmetacrylate used as bone cement
A infecção bacteriana é a principal complicação que um procedimento de artroplastia de quadril ou joelho pode apresentar. Mesmo após a incorporação de antibiótico (gentamicina) ao cimento ósseo, as taxas de infecções após este procedimento cirúrgico continuam gerando sérios prejuízos para o hospital e para o paciente. As principais bactérias

3. Estudo da reação tecidual à administração intraperitoneal de polimetilmetacrilato (PMMA) em ratos da linhagem Wistar
This experimental study aims to analyze the responses and tissue migration of Polymethylmetacrylate (PMMA) after implantation in the peritoneal cavity of rats. Methods: We used 80 male Wistar rats, adult, weighing between two hundred and ninety-four hundred grams, distributed in randomly in 4 groups: Group in which it was administered 0.4 ml of 0.9% saline S

4. Rheological behavior of PMMA/PS polymer blends compatibilized or not. / Estudo do comportamento reológico da mistura polimérica PMMA/PS compatibilizada ou não.
In this work, the dynamic behavior of polymethylmetacrylate/polystyrene (PMMA/PS) blends to which P(S-co-MMA) was added was studied. Several blend composition and copolymer concentrations were studied. The rheological behavior of blends was compared to Bousminas[1] and Paliernes generalized[2] models. The relaxation spectra of the blends were also inferred,

5. Fabricação e caracterização de Guia de Onda Polimerica a base de PMMA modificado por plasma de CHF3 / Polymeric optical waveguides fabricated by plasma fluorination process
Polymeric optical devices have been studied in communication and interconnection optics due to the intrinsic versatility of polymers molecular structure, that allows advantageous refractive index modeling for core and cladding, and also to their easy fabrication process or patterning capability. PMMA, polymethylmetacrylate, shows the best optical properties
