BACKGROUND: With the rapid development of industrialization andmodernization of the society, caused by trauma to the limb (finger) in patients withincreasing. The proportion of patients due to systemic multi-trauma condition ofinstability can not be the emergency line replantation to be in stable condition afterlimb (finger) is often the ability to save technology, but relevant to [...]
Periodontal disease is the reason which caused periodontal tissue defects eventually leadto teeth missing.It’s the problem that how to prevent tissue from defects effectively and keepthe function.Tissue engineering brings the new technology.How to choose the ideal seed cellsand the meet the requirements scaffold material is the most importantObjective To establish a model of dog periodontal [...]
BACKGROUND:Under the theory of bone-tissue engineering, biocompatibility of biomaterial is evaluated by observing the morphous and determining the multiplication and differentiation rate of osteoblasts on biomaterials.OBJECTIVE:To observe the effects of nano-hydroxyapatite-collagen-rhBMP-2(nHAC/rhBMP-2) on proliferation and differentiation of osteoblasts.Evaluating the osteoeytes compatibility of composite materials from the area of cytology, while comparing with the allogeneic bone.To provide [...]
Automobile possession increase year by year with the development of Chinesenational economy, and traffic accident is also followed frequently. In a large amount oftraffic accident, the proportion of head injury is very important, the high of disabilityrate and mortality cause many social and economic problems, such as directlyeconomic loss and family misfortune. So all over [...]
Objective:To observe the effect of salvianolic acid B postconditioning on morphology and biomechanics of decellularized porcine aortic valve, providing theoretical support for tissue engineering.Methods:Fresh aortic valves from porcine of6to7month were divided randomly into three groups(40valve leaflets in each group).Porcine aortic valve leaflets were treated by two different methods. Control group1involved treatment with Triton-x100、sodium deoxycholate、DNase and [...]
The core of tissue engineering is to build a complex three-dimensional space ofcells and porous materials, which is to promote the implantation of cell’s adhesion,proliferation, differentiation and metabolism. Therefore, how to effectively prepared tomeet the needs of the porous scaffold is of concern. Among many fabricated methods,solvent casting/porogen leaching (SC/PL) is one of the most [...]
Experimental purposes: In order to adjust the setting time and degradability of (tetracalciumphosphate TTCP+dalcium hydrogen phosphate DCPA) system bone cement, optimize itscompressive strength, improve its bioactivity, we try to compound C3S that we have prepared toTTCP+DCPA system bone cement, and explore the physical and chemical properties of thecomposite bone cement.Experimental methods:(1) The stting time of [...]
When the human body is doing exercise, the skin surface above the muscles will produce a weak biological signal, which is called surface electromyography. The biological signals can be a true reflection of the body of the movement, and the way to extract the signal is simple, painless, and noninvasive. Using the scientific methods, researchers [...]
BackgroundThe sternum is a flat bone located in the middle of the chest wall，The shape ofdagger，Sternal manubrium, sternum, xiphoid. Sternum on both sides of ribsconnected to constitute the thorax, since an important role in the protection of themediastinum and chest visceral. If the sternum lesions occur, such as: congenitalmalformations, dysplasia, refractory sternal osteomyelitis, traumatic sternalcomminuted, [...]
Biomedical polymer material is a kind of advanced material which have special functions on reparation, replacement and regeneration of organic tissues. In recent years, it has become one of the most fast growing biological materials.For the biomedical polymer materials, their biological properties not only depend on its own nature, to a large extent, it also [...]
