  • Patent number: 6555116
    Abstract: Thioredoxin, a small dithiol protein, is a specific reductant for allergenic proteins and particularly allergenic proteins present in pollen and animal and plant sources. All targeted proteins contain disulfide (S—S) bonds that are reduced to the sulfhydryl (SH) level by thioredoxin. The proteins are allergenically active and less digestible in the oxidized (S—S) state. When reduced (SH state), they lose their allergenicity and/or become more digestible. Thioredoxin achieved this reduction when activated (reduced) either by NADPH via NADP-thioredoxin reductase (physiological conditions) or by lipoic acid chemical reductant. Skin tests carried out with sensitized dogs showed that treatment of the pollens with reduced thioredoxin prior to injection eliminated or decreased the allergenicity of the pollen. Studies showed increased digestion of the pollen proteins by pepsin following reduction by thioredoxin.

  • Patent number: 6501578
    Abstract: A line of sight laser communication system includes a laser to generate a laser signal with femtosecond pulses. A first grating spectrally disperses the femtosecond pulses of the laser signal. A programmable mask converts the femtosecond pulses of the laser signal into coded words. A second grating spectrally recombines the coded words of the laser signal. A telescope then launches the laser signal. The launched laser signal is received at a receiving telescope. A second laser generates a set of reference pulses. A non-linear crystal combines the set of reference pulses and the laser signal to create an output signal only when the laser signal and the reference pulses temporally coincide. A camera records the output signal.

  • Patent number: 6465235
    Abstract: Novel carbonyl hydrolase mutants derived from the amino acid sequence of naturally-occurring or recombinant non-human carbonyl hydrolases and DNA sequences encoding the same. The mutant carbonyl hydrolases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant carbonyl hydrolase to encode the substitution, insertion or deletion of one or more amino acids in the amino acid sequence of a precursor carbonyl hydrolase. Such mutants have one or more properties which are different than the same property of the precursor hydrolase.

  • Patent number: 6436655
    Abstract: A method for determining the existence and the amount of soluble fibrin contained in a specimen fluid is provided. The method includes the steps of precipitating soluble fibrin out of the opaque specimen fluid, aggregating the soluble fibrin precipitates in a limited region of a transparent container so as to render the precipitates optically detectable in the opaque specimen fluid, and optically detecting the precipitates. The amount of soluble fibrin may be determined by measuring the time from the addition of the precipitating regent to the detection of the soluble fibrin precipitates. Methods of the present invention allow one to measure soluble fibrin in whole blood, and therefore render the test useful in the operating room under conditions of major surgery and in the presence of severe trauma wherein DIC is likely to supervene.

  • Patent number: 6436078
    Abstract: A housing is secured to an area of skin to allow suction to be applied to a local area of skin through an aperture. After formation of a suction blister, a blade is actuated to sever a suction cup thereby detaching the means for creating suction at the aperture and at the same time removing the roof of the suction blister to expose an area of dermis from which the skin's epidermis has been removed. A rotatable portion of the apparatus is then moved into a position in which a port communicates with a compartment within the rotatable portion. The compartment may contain a reservoir of fluid substance to be transdermally absorbed or may contain means for taking a sample of exudate produced at the exposed dermis. A modified apparatus has means for applying suction to the exposed dermis to enhance the rate at which exudate is formed and for handling a sample of exudate for analysis. Transdermal delivery and sampling are thereby achieved non-invasively and without the impediment of the skin's epidermis.
