    Abstract: The present invention provides a process for determining genotypes in highly polymorphic systems by polymerase chain reaction amplification of cDNA or genomic DNA and direct sequencing polymerase chain reaction products using oligonucleotide primers. More specifically, Class II and Class I HLA genotypes can be unambiguously determined in any subject in 16-24 hours by direct sequencing of DRB, DQB, DQA, DPB, DPA, HLA-A, HLA-B and HLA-C- transcripts enzymatically amplified using a limited number of non-allele-specific oligonucleotides. Total cellular RNA from peripheral blood mononuclear cells is reverse transcribed using antisense primers, specific for different locus (DQB, DQA, DPA, or DPB) or group of loci (DRB1-5, or HLA-A and HLA-B and HLA-C). The synthesized cDNA molecules are then enzymatically amplified using different combinations of oligonucleotides for each locus and directly sequenced with Taq polymerase using an internal oligonucleotide. The sequenced genes are then analyzed.

    Abstract: A bioartificial liver (30) to provide liver function to patients with liver insufficiency or failure is disclosed. The bioartificial liver is based on a bioreactor of the type having two fluid paths (42, 46) separated by a permeable medium (38). The bioreactor can be of either hollow fiber or flat-bed configuration. In the configuration using hollow fibers (40), the two fluid paths correspond to the cavity (36) surrounding the hollow fibers (the extracapillary space), and to the lumens of the hollow fibers themselves. Both fluid paths have inlet and outlet ports. Communication between the two fluid paths is across the permeable medium - the hollow fiber material. Hepatocytes (34) are inoculated into the hollow fibers in a solution which quickly forms a highly porous gel. The gel subsequently contracts, leaving an open channel within the hollow fiber adjacent to the gel core entrapped hepatocytes. This channel can be perfused with nutrient media for the hepatocytes.

    Abstract: The present invention provides a method and apparatus for the automated reproduction of three dimensional objects of complex and unique geometry. A computer acquires data describing an object and its surroundings, constructs a computer-based three dimensional model of the object from that data, superimposes an ideal geometry on the computer-based model, alters the ideal geometry to fit the form and function required of the reproduction, and then guides a milling machine in the fabrication of the reproduction. In contrast to the prior art, the present invention does not require human intervention in the reproduction process. The present invention provides two preferred embodiments for the automated high precision reproduction of objects of complex and unique geometry. Both embodiments can machine reproductions solely from generic forms stored in the computer, thus eliminating the need for scanning. Alternatively, the reproductions may be machined solely from scanned data, without resort to generic forms stored in the computer.
