    • The invention describes a novel method for determining the mass of vital tumor cells of xenotransplants in animal models. Cells altered by genetic engineering which form a tumor after transplantation synthesize an excreted reporter gene. This is shown by way of example for a secreted form of human placenta-specific, alkaline phosphate (SEAP). The latter can be demonstrated in the serum of test animals or in culture supernatants. The activity of SEAP in the serum correlates with the number of vital tumor cells in the animal and can be measured prior to the formation of a palpable tumor. The invention shows the use of cell lines altered by genetic engineering in such a manner in subcutaneous and orthotopic tumor models. Dicistronic, eukaryotic expression vectors are used for the stable transfection of the mammalian cell lines or tumor cells used. These vectors contain, under the control of a constitutive or inducible promotor element, the gene coding for SEAP, coupled with a second gene. This latter gene codes e.g. for a receptor tyrosine kinase such as erbB2/HER2 which transforms during overexpression.
    • 本发明描述了用于确定动物模型中异种移植物的重要肿瘤细胞的质量的新方法。 通过基因工程改变的细胞在移植后形成肿瘤合成排泄的报道基因。 这通过例如人胎盘特异性碱性磷酸盐(SEAP)的分泌形式的方式示出。 后者可以在测试动物的血清或培养物上清液中证实。 血清中SEAP的活性与动物中重要的肿瘤细胞的数量相关,并且可以在形成可触及的肿瘤之前测量。 本发明显示了通过基因工程改变的细胞系在皮下和原位肿瘤模型中的使用。 双顺反子,真核表达载体用于稳定转染所用的哺乳动物细胞系或肿瘤细胞。 这些载体在组成型或诱导型启动子元件的控制下含有编码SEAP的基因,加上第二个基因。 后一种基因编码例如 用于在过表达期间转化的受体酪氨酸激酶如erbB2 / HER2。

    • An adaptor for connecting a chip card to a PCMCIA-standard computer slot has a housing with a top cover, a separate bottom cover, and at least one intermediate insulative element or frame connecting the top cover to the bottom cover at a spacing to one another. The top cover and bottom cover have substantially congruent outer contours. The housing has a receiving channel. A printed circuit board is mounted in the housing and extends parallel to the receiving channel. The circuit board has contact elements for electrically contacting a chip card received in the receiving channel. The housing has a front face and a back face wherein the front face has an insertion slot communicating with the receiving channel. The back face has a contact plug electrically connected to the printed circuit board and adapted to electrically contact the PCMCIA-standard computer slot. Cams at the channel entrance are used for card retention. The intermediate element is formed of plural parts which are joined by pins fitted into holes and which are molded about tabs that extend from the covers.
