  • Patent number: 8835665
    Abstract: Methods for recovery of recyclable water and/or fermentation co-products from thin stillage process streams. Microbial metabolites plant derivatives and/or plant extractives are removed from thin stillage after which water is recovered and recycled. Thin stillage is commingled with polar organic solvents or with oil to react microbial metabolites, plant derivatives and/or plant extractives. The reacted organic solvents are then separated from the processed thin stillage. Thin stillage may be commingled with an oil to re act with certain organic compounds, after which, the reacted oil is separated from the processed thin stillage is further extracted with one or more polar organic solvents. Alternatively, thin stillage may be first processed with one or more polar organic solvents, and then processed with an oil. Useful organic compounds may be recovered from the reacted oil and reacted organic solvents.

  • Patent number: 8383172
    Abstract: Methods for separation and recovery of individual cyclic peptides from plant materials, said method comprising the steps of: (a) extracting an oil from a plant material; (b) separating the extracted oil into a non-polar fraction and a polar fraction; (c) separation and recovery of cyclic peptides from the non-polar fraction, and (d) separation and recovery of cyclic peptides from the polar fraction. The methods are suitable for separation and recovery of individual cyclolinopeptides from flax seed oil. Individual cyclolinopeptides are useful for modulation physiological disorders associated with apoptosis. Modified flaxseed oils may be produced by commingling flaxseed oils absent cyclolinopeptides, with at least one cyclolinopeptide separated and recovered with the methods disclosed herein.

  • Publication number: 20040248197
    Abstract: A diagnostic test for preclinical and clinical Alzheimer's disease is based on plasma levels of A&bgr;40, A&bgr;42, their ratio, or their rate of entry following administration of antibodies that sequester A&bgr;. Alterations of any of these parameters from control values identifies preclinical or clinical Alzheimer's disease.

  • Publication number: 20040192898
    Abstract: This invention provides variant 266 antibodies that are engineered to lack an N-glycosylation site within the CDR2 of the heavy chain, pharmaceutical compositions thereof, and polynucleotide sequences, vectors, and transformed cells useful to express the variant antibodies. The variants sequester soluble A&bgr; peptide from human biological fluids and specifically bind an epitope contained within position 13-28 of the amyloid beta peptide A&bgr; with significantly greater affinity than either mouse antibody 266 or humanized 266 antibodies retaining N-glycosylation sites. The variant antibodies are useful for treatment or prevention of conditions and diseases associated with A&bgr;, including Alzheimer's disease, Down's syndrome, cerebral amyloid angiopathy, mild cognitive impairment, and the like.
