OBJECTIVES:To detect the physical characteristics of allogenic arteries cross-linked by Dye-mediated photooxidation (DMP) and Genipin (GP), as well as its biological propreties after being treated with allogenic vessel transplant and internal bloodstream, based on the former researches that biological tissue which have gone through different cross-linked methods will show up different biological propreties. Besides, an [...]
Clinical pressure sore is a disease which has high incidence and is difficult to cure. In order to prevent it we should study its medical principle. Medically, human tissue oxygenation, which includes the weighted average of the blood oxygen saturation and the blood hemoglobin concentration in the microvessels in human tissue, can be monitored mom-invasively, [...]
ObjectiveCartilage defects is always a big problem in the clinical work. The limit source of autologous cartilage and the high absorption rates of allograft cartilage are limiting the application of adult cartilage tissue.Recently the development of tissue engineering has brought new solutions to this problem,a large number of studies on cartilage tissue engineering drive the [...]
ObjectiveTo explore how to isolate and culture the rabbit peripheral blood mesenchymal stem cells (PBMSCs) under the conditions of the skin injury, and to observe their differentiation potential into the bone and cartilage cells. The effective method for the isolation and culture of rabbit peripheral blood mesenchymal stem cells will provide the experimental basis for [...]
Retina, as the first stage of visual pathway, converts the optical visual signal to electrical signals and arouses action potentials in ganglion cells, which then transfer the visual information to higher perceptive cortex. It is of great significance to study the response properties and coding methods of ganglion cells, which helps to explain the working [...]
Objective The current study utilized the degradation of laminin and Col IV by MMP-7 on the basis of our previous studies, with another treatment to xenogenic(porcine) acellular dermal matrix(Xeno-ADM) by MMP-7 after decellularization, was performed to investigate the feasibility of reducing the immunogenicity in xenogenic(porcine) acellular dermal matrix(Xeno-ADM), which contains only dermal reticular layer, and [...]
In the biomedical engineering field, the study of ECG waveform characteristics has been a hotspot,at the same time, the realization of automatic ECG analysis and diagnosis capabilities will greatly promote China’s medical industry.In this paper, a ECG signal analysis and diagnosis system has designed for the practical application,which was also a software engineering tool for [...]
Purpose:To study the bone regeneration guided by silk fibroin/hydroxyapatite (SF/HA) membrane in rabbit radii defects.Methods:After the SF membrane was prepared by degumming method, the SF/HA membrane was developed by alternate soaking method. The models of 10 mm segmental defects were established in both radii of 9 adult New Zealand white rabbits. 6 as experimental group, [...]
Tissue engineering is an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve tissue function or a whole organ. Scaffold material is one of the three factors of tissue engineering. Following the guidance of the performance standards of scaffold materials in tissue [...]
