Nile tilapia skin (Oreochromis niloticus) for burn treatment: ultrastructural a...
Verde, Maria Elisa Quezado Lima; Ferreira Júnior, Antonio Ernando Carlos; Barros Silva, Paulo Goberlânio de; Miguel, Emilio de CastroNile tilapia (Oreochromis niloticus) skin is a well-known biomaterial used as an occlusive dressing for burn treatment. It is also an inexpensive and important source of collagen. This study aims to describe the ultrastructural aspects of Nile tilapia skin, assess its collagen amount and organization, and compare quantitative methods of histochemical and immunohistochemical analysis (in all sterilization steps ...

Silva, Paulo Goberlânio de Barros; Verde, Maria Elisa Quezado Lima; Brizeno, Luiz André Cavalcante; Wong, Deysi V. T.Abstract Immune cell profile of dental pulp tissue treated with zoledronic acid. International Endodontic Journal. Aim To characterize the pulp immune cell profile in the teeth of rats treated with zoledronic acid (ZA). Methodology Male Wistar rats (n = 6 per group) received four intravenous infusions of ZA at doses of 0.04, 0.20 or 1.00 mg kg 1 ZA or saline (control). On the 70th experimental day, they were euth...
Avaliação microscópica, estudo histoquímico e análise de propriedades tensiomét...
Alves, Ana Paula Negreiros Nunes; Verde, Maria Elisa Quezado Lima; Ferreira Júnior, Antônio Ernando Carlos; Silva, Paulo Goberlânio de BarrosOBJECTIVE: To characterize the Nile tilapia skin, a possible source of biomaterial for grafting, from their physical (tensile strength) and histomorphological characteristics, and from collagen classification. METHODS: Samples of Nile tilapia skin were used and, for microtensile tests (by Instron® universal testing machine), were subjected to immersion in glycerol solutions of increasing concentration. Part of ...
