The past, present and future of bovine pluripotent stem cells: a brief overview
Xiuchun TIAN
Frontiers of Agricultural Science and Engineering 2019, Volume 6, Issue 1, Pages 3-7 doi: 10.15302/J-FASE-2018247
Although the pursuit of bovine embryonic stem cells started more than 26 years ago for the purpose of gene-targeting, true pluripotent stem cells in this economically important species are still elusive. With the rapid advances in genome-editing and cloning using homologously recombined somatic cells, the need for pluripotent stem cells for precise genetic modification in any species became questionable. With the pig being the better model for human regenerative biology, the identification of the commonalities and uniqueness of the pluripotency circuitry across mammalian species may be the main objective for studying pluripotent stem cells in the bovine.

Machinery fault diagnosis has progressed over the past decades with the evolution of machineries in terms of complexity and scale. High-value machineries require condition monitoring and fault diagnosis to guarantee their designed functions and performance throughout their lifetime. Research on machinery Fault diagnostics has grown rapidly in recent years. This paper attempts to summarize and review the recent R&D trends in the basic research field of machinery fault diagnosis in terms of four main aspects: Fault mechanism, sensor technique and signal acquisition, signal processing, and intelligent diagnostics. The review discusses the special contributions of Chinese scholars to machinery fault diagnostics. On the basis of the review of basic theory of machinery fault diagnosis and its practical applications in engineering, the paper concludes with a brief discussion on the future trends and challenges in machinery fault diagnosis.

Strategic Study of CAE 2009, Volume 11, Issue 8, Pages 29-37
Low permeability oil and gas resource of China is abundant and has a great potential of exploration and development. Great exploration discoveries in low permeability sandstone, marine carbonate and volcanic rock fields were acquired and top international matching development technology in low permeability was created. Scale effective development in low permeability oil and gas reservoir was achieved. Oil and gas production in low permeability reservoir increased continuously and the proportion in production components is increasing yearly. New proved reserves and remaining oil and gas reserves considered, low permeability oil and gas resource is the main objects of exploration and development in future. Low permeability resources are the mainstream of exploration and development in China oil and gas industry and have an immense strategic importance for nation energy security.

Three-dimensional reconstruction of light microscopy image sections: present and future
Yuzhen Wang,Rui Xu,Gaoxing Luo,Jun Wu
Frontiers of Medicine 2015, Volume 9, Issue 1, Pages 30-45 doi: 10.1007/s11684-014-0337-z
Three-dimensional (3D) image reconstruction technologies can reveal previously hidden microstructures in human tissue. However, the lack of ideal, non-destructive cross-sectional imaging techniques is still a problem. Despite some drawbacks, histological sectioning remains one of the most powerful methods for accurate high-resolution representation of tissue structures. Computer technologies can produce 3D representations of interesting human tissue and organs that have been serial-sectioned, dyed or stained, imaged, and segmented for 3D visualization. 3D reconstruction also has great potential in the fields of tissue engineering and 3D printing. This article outlines the most common methods for 3D tissue section reconstruction. We describe the most important academic concepts in this field, and provide critical explanations and comparisons. We also note key steps in the reconstruction procedures, and highlight recent progress in the development of new reconstruction methods.

Strategic Study of CAE 2005, Volume 7, Issue 5, Pages 30-34
With the development of turbot cultivation and market, turbot has been proved to be a high-quality species grown-out in China. After several-year practice, the primary intensive culture model has formed in the northern part of China. The production of turbot fries in the year 2004 is around 35 million and the commercial fish 20 thousand tonnes. As a result, China has become one of the largest countries in turbot culture and consumption in the world. Turbot culture industry has not only made great contribution to the development of marine culture industry and the littoral areas economy but also laid a theoretical and practical foundation for the intensive marine fish culture industry in China. Particularly, the accession of China to WTO brought new development opportunity for turbot culture. Those new ideas and objectives are driving the turbot culture industry into an updated stage, on which turbot will be developed in a standardized, large scale genetic breeding, the industry of special formula feeds with balanced nutrition, and the recirculation system.
