1CD44v对大鼠多形胶质瘤细胞系RG2的转移促进作用显示文摘研究颅外生长的胶质母细胞瘤能否转移以及CD44v对它们转移能力的影响。利用基因转染技术,将自发表达CD44v(meta-1)的载体导入转移力较低的大鼠胶质瘤RG2细胞内,并对有或无CD44v表达的RG2细胞做系统的实验性转移观察。结果发现,与无CD44v表达的母系RG2细胞(RG2-m)相比,CD44v的转染子RG2-a的生长指标和形态学特点并无明显改变;但RG2-a在荷瘤大鼠体内转移出现的时间明显提前,在单位时间内,受累器官的数量增加和破坏程度更为严重。研究结果证实:颅外生长的胶质母细胞具有自发转移能力,CD44v可明显提高RG2细胞的转移效率。李宏 Martin Hofmann 刘佳 江岩 郭丽 罗阳 鲁海欧 1996中华肿瘤杂志1996,18,5:12
2Hybrid multi-chip assembly of optical communication engines by in situ 3D nanolithography显示文摘Three-dimensional(3D)nano-printing of freeform optical waveguides,also referred to as photonic wire bonding,allows for efficient coupling between photonic chips and can greatly simplify optical system assembly.As a key advantage,the shape and the trajectory of photonic wire bonds can be adapted to the mode-field profiles and the positions of the chips,thereby offering an attractive alternative to conventional optical assembly techniques that rely on technically complex and costly high-precision alignment.However,while the fundamental advantages of the photonic wire bonding concept have been shown in proof-of-concept experiments,it has so far been unclear whether the technique can also be leveraged for practically relevant use cases with stringent reproducibility and reliability requirements.In this paper,we demonstrate optical communication engines that rely on photonic wire bonding for connecting arrays of silicon photonic modulators to InP lasers and single-mode fibres.In a first experiment,we show an eight-channel transmitter offering an aggregate line rate of 448 Gbit/s by low-complexity intensity modulation.A second experiment is dedicated to a four-channel coherent transmitter,operating at a net data rate of 732.7 Gbit/s-a record for coherent silicon photonic transmitters with co-packaged lasers.Using dedicated test chips,we further demonstrate automated mass production of photonic wire bonds with insertion losses of(0.7±0.15)dB,and we show their resilience in environmental-stability tests and at high optical power.These results might form the basis for simplified assembly of advanced photonic multi-chip systems that combine the distinct advantages of different integration platforms.Matthias Blaicher Muhammad Rodlin Billah Juned Kemal Tobias Hoose Pablo Marin-Palomo Andreas Hofmann Yasar Kutuvantavida Clemens Kieninger Philipp-Immanuel Dietrich Matthias Lauermann Stefan Wolf Ute Troppenz Martin Moehrle Florian Merget Sebastian Skacel Jeremy Witzens Sebastian Randel Wolfgang Freude Christian Koos 2020Light(Science & Applications)2020,9,1:4
