The nuclear transplantation technique is known as the most potential and efficient method for producing large numbers of genetically identical animals from a single embryo and somatic cells. After Dolly was introduced in 1997, many scientists were amazed. A possibility came to a reality that live offspring could be produced with differentiated somatic cells from an adult animal. On the other side, many in the press and the sensationalists focused on the socially, ethically and scientifically unacceptable sides of the technology. In this article, the history, current status and prospects of the technological development of nuclear transplantation in mammals and its application to the production of cloned animals are described. For the efficient and successful production of cloned embryos by nuclear transplantation, the right selection, preactivation and micromanipulation of oocytes as capacious recipient cytoplasm, the adequate and benefitial preparation of multiple totipotent embryonic and somatic cells as donor nuclei, fusion of them and in vitro production of cloned embryos are very critical. Recently the overall efficiency of production of cloned embryos and offspring in livestock has been much improved. Cloning will also be a more efficient, faster and useful way of creating transgenic fetuses for gene therapies, gene pharming, organs for xenotransplantation by preselection and mass production of transgenic embryos and consequently improving the production efficiency in transgenic animals. Further technical development of nuclear transplantation will enable large-scale production of cloned livestock and in near future the commercial cloning of animals will become a reality.

Laser cleaning has the advantages of environmental protection, precision, and high efficiency, and has good prospects for application in removing oxide films on the surface of aluminum alloy. This paper discusses the cleaning threshold and cleaning mechanism of aluminum alloy surface oxide film. A nanosecond pulsed laser was used to remove a 5-㎛-thick oxide film from the surface of 7A04 aluminum alloy, and the target surface temperature and cleaning depth were simulated. The effects of different laser energy densities on the surface morphology of the aluminum alloy were analyzed, and the plasma motion process was recorded using a high-speed camera. The temperature measurement results of the experiment are close to the simulation results. The results show that the laser cleaning of aluminum alloy oxide film is mainly based on the vaporization mechanism and the shock wave generated by the explosion.

Plants are exposed to various types of stresses in their surroundings, and stress-resistant and regulatory proteins are produced as defense mechanisms. Abscisic acid is well known for its important role in stress signals as a phytohormone and is also involved in the physiological reactions of plants such as leaf senescence and seed dormancy. In particular, it has been found to perform a variety of functions in other biological systems, such as animals and microalgae, not plants. In this review, the biosynthesis and signaling process of abscisic acid and its function were investigated and the future prospects for the industrial application of abscisic acid in various biotechnologies, including agriculture, biomedical and industrial biotechnology, have been proposed based on study of emerging applications such as increased crop yields, disease treatment development and bioenergy production.

Atherosclerosis, a disease with high morbidity and mortality worldwide, is a chronic inflammatory disease that is a major cause of cardiovascular diseases such as stroke and myocardial infarction. Atherosclerosis is characterized by the accumulation of lipid deposits in the arteries, forming atheromas. This leads to the narrowing of the arteries and thrombosis. Recently, the need to develop bio-derived anti-atherosclerotic materials has been highlighted with concerns about the side effects of synthetic therapeutics. Accordingly, related research (such as the discovery of biomaterials for the improvement and treatment of atherosclerosis and the identification of mechanisms) has been actively conducted. Biomaterials including polysaccharides, polyphenols, and coenzyme Q10 have been reported to inhibit or delay symptoms by modulating factors involved in the development of atherosclerosis. For biomaterials with superior activity, in vivo anti-atherosclerotic activity has been confirmed. In this review, the pathogenesis of atherosclerosis was investigated, and the current status and application prospects of biomaterials with anti-atherosclerotic activity were proposed.
