2. YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy
Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac matrix remodeling. A classic model of DCM was established

3. A Randomized Comparative Study of Two Techniques to Optimize the Root Coverage Using a Porcine Collagen Matrix
Resumo: O objetivo deste estudo randomizado, controlado e clínico foi comparar para recobrimento radicular a técnica de retalho estendido (EFT) com a técnica de retalho avançado coronalmente (CAF) utilizando uma matriz suína colágena (PCM). Vinte pacientes com duas retrações gengivais bilaterais, classe I ou II de Miller em dentes não molares foram

4. Avaliação in vitro de matriz colágena suína como arcabouço tridimensional para cultivo de fibroblastos gengivais / In vitro evaluation of porcine collagen matrix as a threedimensional scaffold for gingival fibroblasts seeding
Introdução: Fibroblastos gengivais desempenham um importante papel na regeneração de tecidos moles de proteção. Mucograft® (MCS-3D) é um substituto xenógeno novo que vem sendo utilizado na periodontia em técnicas de recobrimento radicular e aumento de tecido queratinizado. O objetivo do presente estudo foi avaliar morfológica e imunohistoquimicame

5. Desenvolvimento e caracterização de dispositivo de PLLA/Trietil-Citrato associado à derme suína acelular para reparação de lesões cutâneas / Development and characterization of PLLA/Triethyl citrate device associated to acellular dermal matrix to repair cutanous wounds
One of the challenges of the Tissue Engineering is to promote a better functioning of organs and tissues damaged by diseases or traumas. With target for developing a biphasic device for future regeneration and dermal application in Tissue Engineering and Regenerative Medicine, fibroblasts from VERO cell line were cultivated on a porcine acellular dermal matr

6. Mineralização in vitro de matrizes de colágeno aniônico derivadas de tecidos biológicos / In vitro mineralization of anionic collagen matrices
The reconstruction of osseous defects is still a problem that affects millions of people and medicine tries to solve it. One alternative to solve these problems has been the development of biomaterials that can be used as inductors in the osseous repair process. Collagen is a natural polymer able to promote healing and bone regeneration, and among hydroxyapa

7. Avaliação do metabolismo celular decorrente da aplicação de força nos condrócitos do côndilo mandibular e do joelho de suínos / Comparison of in vitro desponse to mechanical loading between the porcine mandibular condyle and ankle articular cartilages
Functionally, the mandibular condylar cartilage is similar to the ankle articular cartilage, both provides lubrication to resist friction and offers protection against external mechanical loading. However, the effect of tension loadings on these two articular cartilages remains unclear. The purpose of this study was to evaluate in vitro, the metabolism of th

9. Using porcine acellular collagen matrix (Pelvicol®) in bladder augmentation: experimental study
PURPOSE: Evaluate the rabbit augmented bladder with PelvicolÒ. MATERIALS AND METHODS: Twenty New Zealand rabbits were divided into 4 groups. Bladder augmentation was performed using a 10 x 10 mm sized porcine acellular collagen matrix. The material was placed on the dome of the bladder wall as a patch with 5-0 polyglycolic sutures.

10. Matriz extracelular de pericardio fibroso porcino : estudo morfologico e bioquimico / Extracellular matrix of porcine fibrous pericardium: morphological and biochemical study
Pericardial tissue has been used to construct bioprostheses employed in the repair different kinds of injuries. However, calcification and mechanical failure have been the main causes of limited durability of cardiac bioprostheses constructed with bovine pericardium. In the course of this work a study has been conducted on the porcine fibrous pericardium and

11. Collagen matrices behavior in treatment of skin rat wounds / Comportamento de matrizes de colágeno utilizadas no tratamento de feridas planas induzidas em pele de rato
The potentiality of the use of a collagen based matrix and of a cream prepared by the mixture of a commercial cream plus collagen (90:10 w/w) were evaluated in the healing process of rats skin. The acellular collagen matrix and the collagen gel were obtained by an alkaline treatment of porcine serosa which does not damage the native collagen structure and

12. Exercise training decreases the size and alters the composition of the neointima in a porcine model of percutaneous transluminal coronary angioplasty (PTCA)
Exercise training (EX) following percutaneous transluminal coronary angiography (PTCA) reduces progression to restenosis and increases event-free survival rates. Our aim was to determine whether EX inhibits lesion development and/or alters the extracellular matrix (ECM) composition of the neointima (NI) in a porcine PTCA model. Miniature Yucatan swine were a
