Abstract: The present invention relates to a mathematical and computer model of a joint. The model includes representation of the biological processes related to the synovial tissue and cartilage. In one embodiment, the model represents a human joint afflicted with rheumatoid arthritis.

Abstract: The present invention relates generally to a computer model of an adaptive immune response. One embodiment of the invention relates to a computer model of an adaptive immune response within the framework of signals conveyed at the site of antigen exposure. Another embodiment of the model includes a representation of complex physiological regulatory mechanisms related to, for example, cellular dynamics, mediator production, antigen-presenting cell (APC) recruitment, APC maturation, lymphocyte activation, lymphocyte trafficking, and/or lymphocyte effector function. In another embodiment, the model can account for mediator production in response to antigen within a chronically inflamed peripheral tissue, as well as the regulatory effects of mediators on APC and lymphocyte population dynamics, including maturation, activation, and apoptosis, and the regulatory effects of mediators produced by APCs and lymphocytes on a chronically inflamed peripheral tissue.

Abstract: A method is provided for isolating DNA from eukaryotic cell and flow sorted chromosomes. When DNA is removed from chromosome and cell structure, detergent and proteolytic digestion products remain with the DNA. These products can be removed with organic extraction, but the process steps associated with organic extraction reduce the size of DNA fragments available for experimental use. The present process removes the waste products by dialyzing a solution containing the DNA against a solution containing polyethylene glycol (PEG). The waste products dialyze into the PEG leaving isolated DNA. The remaining DNA has been prepared with fragments containing more than 160 kb. The isolated DNA has been used in conventional protocols without affect on the protocol.
