Content-based image retrieval systems (CBIR-S) are some of the main computational technologies which offer physicians different applications to aid diagnostic processes. They allow similarity queries by extracting pictorial features from medical images. Even though research on S-CBIR started almost two decades ago, there... tde@sc.usp.br (Souza, Juliana Pereira de) Thèse de Doctorat Mon, 06 May 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/82/82131/tde-15022013-144029/?&lang=fr http://www.teses.usp.br/teses/disponiveis/82/82131/tde-15022013-144029/?&lang=fr Osteoporosis, a disease characterized by the reduction of bone mass and deterioration of bone microstructure deterioration, affects the elderly population and hundreds of millions of people worldwide. As a silent disease, its diagnosis occurs, in most cases, after injury, or, bone fracture. In an attempt to detect early signs of the disease, different methods of diagnostic imaging to obtain measures of density and bone architecture are used. Currently, there is great interest in establishing a correlation... tde@sc.usp.br (Rocha, Gabriel Lopes da) Mémoires de Maîtrise Mon, 14 Jan 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/82/82131/tde-04012013-161203/?&lang=fr http://www.teses.usp.br/teses/disponiveis/82/82131/tde-04012013-161203/?&lang=fr One of the prominent challenges in medical dermatology has been the treatment of acne. The acne affects 80 to 90% of teenagers. The search for alternative treatment has become important due to bacterial resistance of P. acnes to usually applied antibiotics against this etiologic agent and the side effects produced by these drugs. In order to overcome these limitations to inactivated the P. acnes, the photodynamic based protocols has been studied. Already, well established named photodynamic therapy... tde@sc.usp.br (Calabrese, Ana Paula Mazine) Mémoires de Maîtrise Mon, 14 Jan 2013 00:00:00 -0300 http://www.teses.usp.br/teses/disponiveis/82/82131/tde-04012013-164556/?&lang=fr http://www.teses.usp.br/teses/disponiveis/82/82131/tde-04012013-164556/?&lang=fr Aiming to obtain biomaterials that act as a support to direct and assist the process of tissue regeneration, natural polymeric materials such as collagen and chitosan have been used.

The surgery aims at rendering the patient free of seizures, without postoperative neurological deficits. In order to accomplish this, it is of major importance to precisely delineate the epileptogenic zone (EZ).
