    • This invention relates to methods for electrofusing biological particles to cells of animal or plant tissues in vitro, in situ, or vivo. Selected biological particles are placed in contact with cells of a selected tissue and fused to cells in the tissue by means of an electric field. The method of this invention may be used to produce animals and plants characterized by features and properties that differ from those typically displayed by the native species. One embodiment of the methods of this invention has been used to produce an animal model for ocular gonorrhea by electrofusing human cells with functional receptors for the human bacterial pathogen Neisseria Gonorrhoeae to epithelial cells in the histologically intact superficial corneal tissue of living rabbits. The methods of this invention may be used to produce other animal or plant models for the study of receptor-mediated processes, including infectivity studies required for the development of vaccines effective to protect against or lessen the severity of infections caused by microbial pathogens. This is achieved by electrofusing cells with membrane receptors for a pathogen to cells of tissues of plants or animals that are normally not susceptible to infection by that pathogen. Other applications are disclosed.
    • 本发明涉及在体外,原位或体内将生物颗粒电气化到动物或植物组织细胞的方法。 将选定的生物颗粒置于与选定组织的细胞接触并通过电场与组织中的细胞融合。 本发明的方法可以用于产生特征在于与天然物种通常显示的特征和性质不同的特征和特征的动物和植物。 本发明方法的一个实施方案已经用于通过将人细胞与人细菌性病原体淋病奈瑟氏球菌的功能受体电融合到活的兔的组织学上完整的表浅角膜组织中的上皮细胞上来产生眼淋病动物模型。 本发明的方法可用于产生用于研究受体介导的过程的其它动物或植物模型,包括开发有效防止或减轻由微生物病原体引起的感染的严重性的疫苗所需的感染性研究。 这通过将具有病原体的膜受体的细胞与通常不易被该病原体感染的植物或动物的组织细胞电融合而实现。 公开了其他应用。

    • A method of preparing a transgenic animal model with enhanced, accelerated pathology for Alzheimer's Disease (AD) and the transgenic animal made by the method are disclosed. The method includes producing an F1 generation by crossing a first and second transgenic parent each carrying a different expressible transgene for differing aspects of the same desired phenotype associated with AD pathology. The offsprings of the F1 generation are then screened and those which carry a transgene from each parental transgenic animal resulting in an enhanced pathology for Alzheimer's Disease are selected. In a preferred embodiment the AD-associated pathology is for amyloid accumulation. In an embodiment a mutant presenilin transgene and a transgene for a mutant amyloid precursor protein are used. In a further embodiment the mutant presenilin transgene is the PS1 M146L mutation and the mutant amyloid precursor protein transgene is the Swedish mutation (app695 isoform containing a K670N, M671L mutation (app770 numbering )).
    • 公开了一种制备具有阿尔茨海默病(AD)增强,加速病理学和通过该方法制备的转基因动物的转基因动物模型的方法。 该方法包括通过与携带不同可表达转基因的第一和第二转基因亲本杂交产生F1代,用于与AD病理学相关的相同所需表型的不同方面。 然后筛选F1代的后代,并选择携带来自每个亲代转基因动物的转基因导致阿尔茨海默病的增强病理学的后代。 在优选实施方案中,AD相关病理学用于淀粉样蛋白积聚。 在一个实施方案中,使用突变型早老素转基因和用于突变淀粉样蛋白前体蛋白的转基因。 在另一个实施方案中,突变型早老素转基因是PS1 M146L突变,突变淀粉样蛋白前体蛋白转基因是瑞典突变(含有K670N,M671L突变(app770编号)的app695同种型))。

    • A method and apparatus for determining the type of a blood sample are provided wherein a turbidity spectrum of the blood sample is collected over a predetermined wavelength range, from which is calculated an extinction spectrum. This extinction sprectrum is then compared with a set of control spectra collected from control blood samples having known blood types, from which the type of the blood sample can be determined. A further method is provided for detecting the presence of a substance in a bodily fluid sample, the substance having a size in the range of generally 0.5 to 20 mu m. Exemplary substances that could be of interest to detect include, but are not limited to, hemoglobin, bilirubin, red blood cell antigens, microorganisms, and viruses. This embodiment includes the additional step of deconvoluting the extinction spectrum to obtain a particle size distribution for comparison with a database of control samples.
    • 提供了一种用于确定血液样本类型的方法和装置,其中在预定波长范围内收集血液样本的浊度谱,由此计算消光谱。 然后将该灭绝性脊椎动物与从具有已知血型的对照血液样品收集的一组控制光谱进行比较,从该血液样品中可以确定血液样品的类型。 提供了用于检测物质在体液样品中的存在的另一种方法,该物质的大小通常在0.5至20μm的范围内。 可能感兴趣的检测的示例性物质包括但不限于血红蛋白,胆红素,红细胞抗原,微生物和病毒。 该实施方案包括解卷积消光谱以获得粒度分布的附加步骤,用于与对照样品的数据库进行比较。
