Purchase of Cryogenic Equipment and EDS System Upgrade

纽约城市学院的生物学家正在申请配套资金来购买透射电子显微镜（TEM）。新的TEM将取代26年前购买的菲利普斯300。新设备辅助的研究领域相当广泛，涵盖神经生物学、分子发育遗传学、免疫生物学、原生生物学、分子系统学、内吞生物学和进化等领域。更具体地说，以下项目将得到帮助：1)有孔虫中含硅藻内共生的吞噬小体-吞噬溶酶体加工；2)有孔虫的核分裂与分类学；3)浮游硅藻分子系统学；4)胸腺护理细胞的细胞表面表型；5)胸腺细胞与胸腺护理细胞的接触；6)果蝇复眼的分子与遗传分析；7)非洲爪蟾（Xenopus laevis）胚胎和变形神经系统轴突发育和连接特异性的分子机制；8)视网膜调节巩膜生长的信号级联过程中涉及的生长因子和神经递质的研究，当巩膜生长发生偏差时，可导致近视。

Biologists at the City College of New York are requesting matching funds to purchase a transmission electron microscope (TEM). The new TEM will replace a Phillips 300 purchase 26 years ago. The research aided by the new equipment is quite broad in aspect, covering fields such as Neurobiology, Molecular Developmental Genetics, Immunobiology, Protistology, Molecular Systematics, Endocytobiology, and Evolution. More specifically the following projects will be aided: 1) Phagosome- phagolysosomal processing in diatom-bearing endosymbioses in foraminifera; 2) Karyokinesis and systematics of foraminifera; 3) Molecular systematics of planktonic diatoms; 4) Cell surface phenotypes of thymic nurse cells; 5) Contact between thymocytes and thymic nurse cells; 6) Molecular and genetic analysis of the Drosophila compound eye; 7) Molecular mechanisms underlying axonal development and connection specificity in the embryonic and metamorphosing nervous system of the frog Xenopus laevis; and 8) Studies of growth factors and neurotransmitters involved in the signal cascade by means of which the retina modulates growth of the sclera which, when awry, can lead to myopia.
