2Projection micro stereolithography based 3D printing and its applications显示文摘Projection micro stereolithography(PμSL)is a high-resolution(up to 0.6μm)3D printing technology based on area projection triggered photopolymerization,and capable of fabricating complex 3D architectures covering multiple scales and with multiple materials.This paper reviews the recent development of the PμSL based 3D printing technologies,together with the related applications.It introduces the working principle,the commercialized products,and the recent multiscale,multimaterial printing capability of PμSL as well as some functional photopolymers that are suitable to PμSL.This review paper also summarizes a few typical applications of PμSL including mechanical metamaterials,optical components,4D printing,bioinspired materials and biomedical applications,and offers perspectives on the directions of the further development of PμSL based 3D printing technology.Qi Ge Zhiqin Li Zhaolong Wang Kavin Kowsari Wang Zhang Xiangnan He Jianlin Zhou Nicholas X Fang 2020International Journal of Extreme Manufacturing2020,2,2:11
3MRI阴性药物难治性颞叶癫痫合并抑郁症患者的静息态功能磁共振研究显示文摘背景抑郁症在颞叶癫痫中发生率高达50%~60%,而30%的药物难治性颞叶癫痫患者可表现为头颅核磁共振(MRI)无明显异常,这部分患者相较于伴有海马硬化的药物难治性颞叶癫痫患者出现继发性全面强直阵挛发作的机率更高。因此,MRI阴性药物难治性颞叶癫痫合并抑郁症的患者,生活质量更差、自杀风险更高,更需要癫痫外科手术治疗。朱曦 陈蕾 罗程 Zhu X He Z Luo C 2018癫痫杂志2018,4,3:11

10Docosahexaenoic acid suppresses arachidonic acid-induced proliferation of LS-174T human colon carcinoma cells显示文摘AIM:To investigate the impact of arachidonic acid (AA) and docosahexaenoic acid (DHA) and their combination on colon cancer cell growth.METHODS:The LS-174T colon cancer cell line was used to study the role of the prostaglandin precursor AA and the omega-3 polyunsaturated fatty acid DHA on cell growth. Cell viability was assessed in XTT assays. For analysis of cell cycle and cell death,flow cytometry and DAPI staining were applied. Expression of cyclooxygenase-2 (COX-2),p21 and bcl-2 in cells incubated with AA or DHA was examined by real-time RT-PCR. Prostaglandin E2 (PGE2) generation in the presence of AA and DHA was measured using a PGE2-ELISA.RESULTS:AA increased cell growth,whereas DHAreduced viability of LS 174T cells in a time-and dose-dependent manner. Furthermore,DHA down-regulated mRNA of bcl-2 and up-regulated p21. Interestingly,DHA was able to suppress AA-induced cell proliferation and significantly lowered AA-derived PGE2 formation. DHA also down-regulated COX-2 expression. In addition to the effect on PGE2 formation,DHA directly reduced PGE2-induced cell proliferation in a dose-dependent manner. CONCLUSION:These results suggest that DHA can inhibit the pro-proliferative effect of abundant AA or PGE2.Piet Habbel Karsten H Weylandt Katja Lichopoj Johannes Nowak Martin Purschke Jing-Dong Wang Cheng-Wei He Daniel C Baumgart Jing X Kang 2009World Journal of Gastroenterology2009,15,9:2

15Cooperation in an asymmetric volunteer's dilemma game with relatedness显示文摘What motivates some members of a social group to voluntarily incur costs in order to provide for the common good? This question lies at the heart of theoretical and empirical studies of cooperative behavior. This is also the question that underlies the classic volunteer's dilemma model, which has been previously explored in scenarios where group members are related or interact asym- metrically. Here we present a model that combines asymmetry and relatedness, showing that the probability of volunteerism in such systems depends closely on both the degree of asymmetry and level of relatedness between interacting individuals. As has been shown in previous volunteer's dilemma models, the payoff ratio and overall group size also influence the probability of volunteerism. The probability of volunteerism decreases with increasing group size or decreasing cost-to-benefit ratio of the coplayers; in the presence of asymmetrical interactions, subordinate players were more likely to offer public goods than the dominant player. More asymmetrical interactions decrease the probability of volunteerism of the dominant player; overall volunteerism increases with increasing relatedness.HE JunZhou WANG RuiWu CHRISTOPHER X J Jensen LI YaoTang LI ChaoQian 2012Chinese Science Bulletin2012,57,16:2
