Tissue engineering using scaffold not only should have biodegradability and a certain 3D structure, but also its morphology structure should be mimetic to that of the repaired natural tissue. So to manufacture the scaffold with a biomimetic structure as the natural tissues is important. In this research, highly porous poly(L-lactic acid) (PLLA) and(More)
The structure of petals and volatile compounds from fresh Styrax tonkinensis cut flowers were investigated by using micro-techniques and a headspace solid-phase micro-extraction technique coupled with GC–MS. Styrax tonkinensis is a fast-growing woody plant that is used for timber and as a medicinal plant. In the present study, the structures of the flower(More)
Our aim was to compare hip arthroplasty with internal screw fixation in the repair of intertrochanteric fractures in elderly patients with osteoporosis. Of 112 included patient, 70 (81.81 ± 4.88 years) received hip arthroplasty with a prosthesis specially designed for intertrochanteric fractures, and 42 (83.46 ± 5.11 years) underwent plate-screw fixation.(More)
OBJECTIVE To examine the biological characteristic changes in the dedifferentiated human articular chondrocytes by the bioreactor culturing in vitro. METHODS The cartilage tissue was obtained from the joints of the adult human. The chondrocytes were isolated from the cartilage tissue with the type II collagenase digestion (0.2%, 37 degrees C, 3 h)and were(More)
Morphological and biochemical changes of Chinese horse chestnut (Aesculus chinensis Bge.) seeds were studied during the process of maturation. Fruit and seed diameter increased linearly from DPA (Days Post Anthesis) 60 to DPA 150 and were stable thereafter. The weight of fruit and seed increased sigmoidally between DPA 100 and DPA 160. The water contents of(More)
The carbon flow balance is shifted to starch rather than oil accumulation during benzoin seed development stage (80–120 DAF) and thereby lipid deposition speed slows down. Benzoin [Styrax tonkinensis (Pierre) Craib ex Hartwich] is a woody oilseed species with potential value as a biofuel feedstock. However, the continuous drop in seed crude fat(More)
