Objective: To investigate the efficacy of a type I collagen-derived artificial tubular implant on sciatic nerve regeneration. Materials and Methods: Sprague-Dawley rat sciatic nerve injury model was built by cutting a 5.0 mm defect on the sciatic nerve of the right thigh. Rats with sciatic nerve injury were treated with type I collagen-derived artificial tubular implants (Group A), autologous c...

Inspired upon the development of living systems, many models of artificial embryogeny are being proposed. These are usually aimed at the solution of some know limitations of evolutionary computation; among these scalability, flexibility and, more recently, fault-tolerance. This paper focuses on the latter, proposing an explanation of the intrinsic regenerative capabilities displayed by some mod...

Taking into account the increasing need to artificial joints for in-vitro use, this paper presents a layout of a challenge leading to detail analyzing of regeneration problems of articular joint and gives a step-by-step plan for designing a novel intelligent artificial joint. This paper has been prepared based on the objective of European Project MTKD-CT-2004-517226 to represent the methodology...

Reforestation can be carried out using natural regeneration or artificial regeneration. There are vari-ous methods for the regeneration, including manual planting, mechanical planting and aerial/or ground seeding. This article aimed to review current reports on productivity of provide a summary rates machines. According review’s results, may vary from 143 475 seedlings per productive ...

Periosteum, a membrane covering the surface of bone, plays an essential role in maintaining function bone tissue—and especially providing nourishment and vascularization during regeneration process. Currently, most artificial periostea have relatively weak mechanical strength rapid degradation rate, they lack integrated angiogenesis osteogenesis functions. In this study, bi-layer, biomimetic, p...
