  • Patent number: 6306612
    Abstract: A method of facilitating vascular growth in a subject in need of such treatment comprises inhibiting EMAP II activity in the subject by an amount effective to stimulate vascular growth in the subject (e.g., in the lungs or heart of the subject). Pharmaceutical formulations useful for carrying out such methods (e.g., an antibody that specifically binds to EMAP II in a pharmaceutically acceptable carrier) and screening techniques useful for identifying additional compounds that can be used for carrying out such methods are also disclosed.

  • Patent number: 6251388
    Abstract: Described herein are methods for producing recombinant forms of asparaginase derived from Wolinella succinogenes. In addition, methods for covalent modification of proteins, including asparaginases, by acylation are also provided. Certain embodiments provide for epitopic-labeling of the amino terminus of W. succinogenes asparaginase. Additional embodiments concern methods for the therapeutic utilization of the native, homotetrameric form of W. succinogenes asparaginase, as well as the use of epitopically-labeled or non-epitopically-labeled recombinant W. succinogenes asparaginase (or a covalently modified analog thereof) in the therapeutic treatment of malignant and non-malignant hematological disease and other diseases where asparagine depletion or deprivation would be efficacious or which respond to asparagine depletion or deprivation, as well as their potential utilization in the therapeutic treatment of autoimmune diseases such as rheumatoid arthritis, AIDS, and SLE.

  • Patent number: 6181957
    Abstract: A non-invasive method for determining blood level of an analyte of interest, such as glucose, comprises: generating an excitation laser beam (e.g., at a wavelength of 700 to 900 nanometers); focusing the excitation laser beam into the anterior chamber of an eye of the subject so that aqueous humor in the anterior chamber is illuminated; detecting (preferably confocally detecting) a Raman spectrum from the illuminated aqueous humor; and then determining the blood glucose level (or the level of another analyte of interest) for the subject from the Raman spectrum. Preferably, the detecting step is followed by the step of subtracting a confounding fluorescence spectrum from the Raman spectrum to produce a difference spectrum; and determining the blood level of the analyte of interest for the subject from that difference spectrum, preferably using linear or nonlinear multivariate analysis such as partial least squares analysis. Apparatus for carrying out the foregoing method is also disclosed.

  • Patent number: 5849996
    Abstract: The present invention relates to non-human transgenic animals which contain a transgene comprising a BCR/ABL gene fusion and which develop leukemia. In a preferred embodiment of the present invention, the transgenic animals exhibit a rapid induction of acute leukemia. The present invention offers the advantage of providing, for the first time, a non-human transgenic animal model system which carries the BCR/ABL gene fusion characteristic of the Philadelphia chromosome and which develops leukemia in a manner directly analogous to the clinical progression of chronic myelogenous leukemia (CML) and/or acute lymphoblastic leukemia (ALL) in humans. This model system for human leukemia may be valuable in obtaining a better understanding of CML and ALL and in developing effective therapeutic regimens.

  • Patent number: 5843921
    Abstract: A therapeutic food composition for treatment of diabetic patients to diminish fluctuations in blood sugar levels and prevent hypoglycemic episodes, comprising per unit about 20-50 grams of nutrients including slowly absorbed or digested complex carbohydrate, preferably uncooked cornstarch; more rapidly absorbed complex carbohydrate; protein; fat; and at least one sweetening agent, but less than about 3 grams of any simple sugar other than fructose. Fructose may be present in the composition in quantities greater than 3 grams per unit. Diabetic patients may be treated to diminish blood sugar fluctuations and prevent hypoglycemia via the administration of the novel food composition as an evening or pre-bedtime snack or during the daytime hours to patients receiving insulin therapy or engaging in activities that might provoke hypoglycemia.

  • Patent number: 5667981
    Abstract: The invention relates to methods and kits for diagnosing cancers arising from cells which express tyrosine phosphorylated CRKL protein, such as cells having the Philadelphia (Ph) chromosome, which includes chronic myelogenous leukemia (CML) and acute lymphoblastic leukemia (ALL), through the detection of increased levels of phosphorylated CRKL protein or through the detection of increased CRKL gene copy or mRNA expression. The invention also relates to methods of treating such cancers.

  • Patent number: 5605893
    Abstract: A therapeutic food composition for treatment of diabetic patients to diminish fluctuations in blood sugar levels and prevent hypoglycemic episodes, comprising per unit about 20-50 grams of nutrients including a slowly absorbed or digested complex carbohydrate, preferably cornstarch; a more rapidly absorbed complex carbohydrate; protein; and fat, but substantially no simple sugars. Diabetic patients may be treated to diminish blood sugar fluctuations and prevent hypoglycemia via the administration of the novel food composition as an evening or pre-bedtime snack or during the daytime hours to patients receiving insulin therapy or engaging in activities that might provoke hypoglycemia.
