1. Desenvolvimento de membranas acelulares de colágeno derivadas de pericárdio porcino para uso em engenharia de tecido / Development of acellular collagen membranes derived from porcine pericardium with potential application in tissue engineering
A utilização e o desenvolvimento de biomateriais para a regeneração tecidual são de grande importância, principalmente para a área médica e odontológica. Matrizes de colágeno derivadas de tecidos de origem animal são utilizadas devido o colágeno apresentar características como biodegradabilidade e biocompatibilidade. Essas matrizes podem ser obt

2. Otimização da liofilização do pericárdio bovino com o auxílio de ferramentas matemáticas / Freeze-drying optimization of bovine pericardium by mathematical modeling
Freeze-drying is a method of preservation that provides high-quality dehydrated products. It is a process that requires time and energy and it may take days to finish. Freeze-drying optimization is used to minimize the process time keeping the high quality of the product. Mathematical models that predict the behavior of products during freeze-drying can dras

3. Performance analysis of the glutaraldehyde treated bovine pericardium valved conduit, implanted in the aortic position in ovines / Análise do comportamento de conduto valvado de pericárdio bovino tratado pelo glutaraldeído, implantado em posição aórtica de ovinos
A necessidade de cirurgia para substituição da aorta ascendente e valva aórtica com reimplante coronariano em grupos especiais de pacientes onde a anticoagulação é indesejável, como nos idosos, é crescente nos últimos anos. Este estudo objetiva desenvolver e avaliar em modelo animal o comportamento de um conduto valvado aórtico feito com pericárdi

4. Traqueoplasty in dogs using equine and swine pericardium preserved in glicerin 98% / Traqueoplastia em cães com emprego de pericárdio equino e suíno conservados em glicerina a 98%
In this experimental study, it was evaluated the use of equine and swine pericardium preserved in glycerin 98% in the repair of surgically provoked tracheal lesions in dogs. The animals were devided in two groups, with ten dogs each, one group treated with equine pericardium and the other with swine pericardium. After twelve hours of water and food restraint

5. The fate of preserved homograft pericardium and autogenous pericardium within the heart
Animal experiments were performed to assess the usefulness of preserved homograft pericardium for intracardiac surgery, with particular reference to the problem of homograft mitral valve papillary muscle fixation. The fate of fresh autogenous pericardium was also studied. Both homograft and autogenous pericardium were destroyed and replaced by fibrous tissue

6. A New Biologic Prosthesis for Vascular Substitute in Mongrel Dogs
New glutaraldehyde-treated vascular prosthesis tubes of bovine pericardium were placed in the abdominal aortas of 29 mongrel dogs and observed for 30 to 540 days. Clinical evaluation was performed during follow-up, and histologic and arteriographic studies were done at the end of the study. Patency was shown by arteriography in 27 of 29 tubes (93.1%). Neoend
