6. Nasal Polyposis: More than a Chronic Inflammatory Disorder-A Disease of Mechanical Dysfunction- The São Paulo Position
Abstract Introduction The importance of our study lies in the fact that we have demonstrated the occurrence ofmechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in

7. Characterization of Decellularized Human Pericardium for Tissue Engineering and Regenerative Medicine Applications
Resumo Fundameto: O enxerto de pericárdio pode ser usado em muitos procedimentos de correção cirúrgica. Uma das estratégias da engenharia tecidual é o processo de descelularização. No entanto, embora esse processo diminua a resposta imunogênica, a descelularização pode modificar tanto o comportamento como a composição da matriz extracelular nat

9. How biomechanics can affect the endodontic treated teeth and their restorative procedures?
Abstract: Endodontic treatment is a common dental procedure used for treating teeth which the pulp tissue has become irreversibly inflamed or necrotic as a result of the carious process or dental trauma. This procedure which involves mechanical and chemical preparation of root canal may affect several mechanical and physical properties of the tooth structure

11. Effects of 1,25-dihydroxycholecalciferol and reduced vitamin D3 level on broiler performance and bone quality
ABSTRACT This study was conducted to evaluate the effect of two levels of vitamin D3 with or without 1,25- dihydroxycholecalciferol (1,25(OH)2D3) on live performance and bone quality of broiler chickens. For that, we used a completely randomized design in a 2 × 2 factorial arrangement, with eight replicates of 30 Cobb®500 male broiler chicks each (n = 960)
