Abstract:
A device and method is described for the collection of breath or air samples into a chemically clean bag or balloon, to facilitate analysis of volatile organic compounds (VOCs) in low concentrations in the collected samples. A reservoir of activated charcoal is introduced into the bag or balloon for initial removal of VOCs and it is then replaced with a similar reservoir of activated charcoal until the bag or balloon is employed to collect a sample. The device fulfills a long-felt need for collection of breath and air samples with a high VOC signal-to-noise ratio.
Abstract:
The present invention provides a method for identifying biomarkers and generating an output indicative of disease. The method for identifying biomarkers comprises the steps of collecting a breath sample from subjects known to have a disease and subjects known to be free of the disease; analyzing the collected breath samples to determine all mass ions in each of the collected breath samples using at least one time-resolved separation technique and at least one mass-resolved separation technique; identifying a subset of the determined mass ions in a processor as the biomarkers for detecting the disease, the subset of the determined mass ions are statistically significant for detecting the disease; and combining the subset of the determined mass ions in a multivariate algorithm in the processor to generate a value of a discriminant function indicating the likelihood that the subject has the disease.
Abstract:
A tissue marking system (120) that includes a first ink reservoir (125) that contains ink of a first color and a second ink reservoir (126) that contains ink of a second color different from the first color. A first isolation space (140) is positioned between the first ink reservoir and the second ink reservoir. A third ink reservoir (127) contains ink of a third color different from the first color and the second color. A second isolation space (145) is positioned between the second ink reservoir and the third ink reservoir.
Abstract:
A method for preparing a dairy protein concentrate, isolate or micellar casein, said method including the steps of: (a) preparing a pasteurised liquid skim milk, whole milk, milk protein concentrate or reconstituted milk feedstock; (b) subjecting the feedstock prepared above to membrane filtration to obtain a retentate having a protein content of between 50% and 95% by weight on a dry matter basis; (c) reacting said retentate with a proteolytic enzyme to modify the protein, for example to cleave the glycomacropeptide (GMP) from kappa-casein. The product of this method has sufficient functionality to enable it to be used as a replacer or extender for rennet casein in the manufacture of food products, particularly analog cheese products.
Abstract:
Disclosed is a method for identifying an individual who has an altered risk for developing colorectal cancer comprising detecting a single nucleotide polymorphism (SNP).
Abstract:
A surgical instrument for use with a trocar that provides access to an interior portion of a patient. The instrument includes an elongated rod portion sized to fit within the trocar and a leg portion attached to the elongated rod portion and movable with respect to the leg portion to define an acute angle therebetween. A marker is attached to the leg portion and is operable to apply a marking substance to the interior of the patient.
Abstract:
The invention relates to a Powder supply system for supplying powder to a powder spray device comprising a powder supply hopper; a powder fluidizing device for fluidizing powder positioned in the powder supply hopper; a powder pump for conveying powder from the powder supply hopper to the spray device. According to the invention the powder supply hopper is pivotally mounted to a support structure. The invention further relates to a method for colour change in a powder supply system.

Abstract:
An arrangement for the collection, concentration, and optional analysis of volatile organic components in a alveolar breath includes a mouthpiece (20), a T-shaped valve unit (30), a breath reservoir (40), and a condensation unit (50) which removes water vapor from the alveolar breath.
