Core-shell hydrogel beads with extracellular matrix for tumor spheroid formation

Creating multicellular tumor spheroids is critical for characterizing anticancer treatments since they may provide a better model of the tumor than conventional monolayer culture. Moreover, tumor cell interaction with the extracellular matrix can determine cell organization and behavior. In this work, a microfluidic system was used to form cell-laden core-shell beads which incorporate elements of the extracellular matrix and support the formation of multicellular spheroids. The bead core (comprising a mixture of alginate, collagen, and reconstituted basement membrane, with gelation by temperature control) and shell (comprising alginate hydrogel, with gelation by ionic crosslinking) were simultaneously formed through flow focusing using a cooled flow path into the microfluidic chip. During droplet gelation, the alginate acts as a fast-gelling shell which aids in preventing droplet coalescence and in maintaining spherical droplet geometry during the slower gelation of the collagen and reconstituted basement membrane components as the beads warm up. After droplet gelation, the encapsulated MCF-7 cells proliferated to form uniform spheroids when the beads contained all three components: alginate, collagen, and reconstituted basement membrane. The dose-dependent response of the MCF-7 cell tumor spheroids to two anticancer drugs, docetaxel and tamoxifen, was compared to conventional monolayer culture.     

Hybrid capillary-inserted microfluidic device for sheathless particle focusing and separation in viscoelastic flow

A novel microfluidic device which consists of two stages for particle focusing and separation using a viscoelastic fluid has been developed. A circular capillary tube was used for three-dimensional particle pre-alignment before the separation process, which was inserted in a polydimethylsiloxane microchannel. Particles with diameters of 5 and 10 μm were focused at the centerline in the capillary tube, and the location of particles was initialized at the first bifurcation. Then, 5 and 10 μm particles were successfully separated in the expansion region based on size-dependent lateral migration, with ∼99% separation efficiency. The proposed device was further applied to separation of MCF-7 cells from leukocytes. Based on the cell size distribution, an approximate size cutoff for separation was determined to be 16 μm. At 200 μl/min, 94% of MCF-7 cells were separated with the purity of ∼97%. According to the trypan blue exclusion assay, high viability (∼90%) could be achieved for the separated MCF-7 cells. The use of a commercially available capillary tube enables the device to be highly versatile in dealing with particles in a wide size range by using capillary tubes with different inner diameters.

论大学校园文化中的公寓文化建设

公寓文化是校园文化的重要组成部分。目前在校园文化特别是公寓文化建设中存在着一些问题,如学校对公寓文化建设重视不够,公寓文化活动仍处于自发性和盲目性状态,缺乏有效的管理监督机制,内涵相对贫乏,网络文化的消极影响严重等。高校应加强对学生公寓的管理,在提升公寓后勤管理队伍的整体素质的同时,通过加强公寓硬件、精神文明、管理服务等方面的建设,营造一个优秀健康、和谐向上的大学生公寓文化氛围,促进大学生的全面健康发展。

陕西民间“夜啼帖”名义考原

流传千年,"夜啼帖"仍然在陕西民间口口相传,其不仅满足了父母照顾孩子的心理需求,同时也是一项非常古老的道教医疗仪式。它的文字可以追溯到明中叶,它止啼的奥秘与道教的医用符咒,道教与巫、医的关系密切,其通过召唤神明祛疾的仪式源自早期道教的"三皇"信仰。作为极少数被民间普遍接受和使用的传统医疗手段,"夜啼帖"背后的民俗文化值得深入探究。
