Abstract: A method of preparing cell samples for viable cell number quantification with a fluorescence digital imaging microscopy system employing digital thresholding technique. The cell sample is stained with a first, fluorescent dye and treated with a second dye that is able to quench the fluorescence of the first dye. The fluorescent dye accumulates in viable cells only and is used to stain the viable cells. The second dye is excluded from viable cells but enters non-viable cells, thereby quenching the background fluorescence in non-viable cells and the medium. Two examples of dye combinations are described: fluorescein diacetate used as the fluorescent dye with eosin Y as the quenching dye; and calcein-AM used as the fluorescent dye with trypan blue as the quenching dye. By reducing the background fluorescence, the dynamic range and accuracy of viable cell number measurements are enhanced.

Abstract: The present invention describes methods for inhibition of tumor growth in the brain, using antagonists of integrins such as &agr;v&bgr;3 and &agr;v&bgr;5. Antagonists of the present invention can inhibit angiogenesis in brain tumor tissue. They can also inhibit vitronectin and tenascin-mediated cell adhesion and migration in brain tumor cells. They can further induce direct brain tumor cell death.

Abstract: A non-invasive method for analyzing the blood-brain barrier includes obtaining a Raman spectrum of a selected portion of the eye and monitoring the Raman spectrum to ascertain a change to the dynamics of the blood brain barrier. Also, non-invasive methods for determining the brain or blood level of an analyte of interest, such as glucose, drugs, alcohol, poisons, and the like, comprises: generating an excitation laser beam (e.g., at a wavelength of 600 to 900 nanometers); focusing the excitation laser beam into the anterior chamber of an eye of the subject so that aqueous humor, vitreous humor, or one or more conjunctiva vessels in the eye is illuminated; detecting (preferably confocally detecting) a Raman spectrum from the illuminated portion of the eye; and then determining the blood level or brain level (intracranial or cerebral spinal fluid level) of an analyte of interest for the subject from the Raman spectrum.

Abstract: A method for controlling bleeding from bones, comprising the use of copolymers of oxyethylene and oxypropylene or mixtures thereof to cover the bleeding portions of bones. The copolymers are resorbable by the body, not metabolized, simple to prepare, inexpensive, readily available, and do not interfere with the fusion, osteogenesis, and related tissue healing and repair of the affected bones.

Abstract: A non-invasive method for determining blood level of an analyte of interst, 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.
