We briefly focus on diverse bioinks used in the recent progresses of biofabrication and 3D bioprinting of various tissue architectures including blood vessel, bone, cartilage, skin, heart, liver and nerve systems. This paper provides readers a guideline with the conjunction between bioinks and the targeted tissue or organ types in structuration and final functionalization of these tissue analogues. The challenges and perspectives in 3D bioprinting field are also illustrated.展开更多

Artificially created, tissue engineered, constructs have the potential to alleviate these concerns with reduced autoimmune response, high anatomical accuracy, long-term patency and growth potential. The advent of 3D bioprinting technology has further supplemented the technological toolbox, opening up new biofabrication research opportunities and expanding the therapeutic potential of the field. In this review, we highlight the challenges facing those seeking to create artificial tubular tissue with its associated complex macro- and microscopic architecture. Current biofabrication approaches, including 3D printing techniques, are reviewed and future directions suggested.展开更多

The computer network is to interconnect the world dispersed and independent computers in accordance with the network protocol. With the rapid development of information technology at home and abroad, the developed countries or parts of the developing countries are strengthening their national information infrastructure. Several of gold projects in information technology as the representative is gradually go deeper, forming an unprecedented development in the entire information network technology. With the globalization of the construction market and intensifying of the competition, construction management requires the higher information technology, which is relatively backward in China＇ s construction industry. So it has important practical significance to clearly recognize the entire network computing model and technology developments, and properly apply to the construction project management.展开更多
