Abstract: Device and method for non-invasively monitoring asthma and other respiratory diseases, as well as non-respiratory diseases. The method includes collecting condensate from a subject's breath, testing the condensate to determine its acetic acid/acetate level or concentration, and evaluating these properties to determine the presence, absence or status of a respiratory or non-respiratory disease in the subject. The method may also include, prior to the testing step, standardizing the volatile substances that may be present within the condensate in a degassing or gas standardizing step. The device includes a mouthpiece apparatus configured to receive breath from a subject, a condensation apparatus to condense the subject's breath and produce a condensate, and a collection apparatus having a collection chamber containing means for testing the condensate to determine the acetic acid and/or acetate concentration.

Abstract: A device (10) and method for non-invasively monitoring asthma and other respiratory diseases. The method includes collecting condensate from a subject's breath, testing the condensate to determine its acidity level or ammonium concentration, and evaluating these properties to determine the presence, absence or status of a respiratory disease in the subject. The method may also include, prior to the testing step, standardizing the volatile substances that may be present within the condensate in a degassing or gas standardizing step. The device (10) includes a mouthpiece apparatus (20) configured to receive breath from a subject, a condensation apparatus (60) to condense the subject's breath and produce a condensate, and a collection apparatus (100) having a collection chamber (102) containing means for testing the condensate to determine its chemical properties. The device (10) also include a system for removing or standardizing the volatile substances that may be present with the condensate.

Abstract: The present invention relates to a method of treating asthma by raising the pH of the airways of an individual. The effect can be mediated directly by administering a pharmaceutically acceptable basic solution or alternatively, the effect can be mediated by enhancing the activity of glutaminase.

Abstract: Disclosed is a device for determination of the content of higher oxides of nitrogen in exhaled breath condensate which comprises a conduit having an exhalate condensing portion with an inlet and an outlet (the inlet can be configured to fit with a mechanical respirator or, for direct use by the patient, an inlet assembly providing one-way ingress of ambient atmosphere to the device can be associated with the inlet of the conduit exhalate condensing portion); a coolant jacket coaxially surrounding said exhalate condensing portion; a gas release port; and, in enclosed fluid communication with said conduit exhalate condensing portion outlet, a sample assay assembly comprising (i) a translucent analysis chamber attached to the outlet to receive condensate fluid and having a reagent entry port, (ii) a reagent chamber in enclosed fluid communication with the reagent entry port and (iii) a pliable element connecting the outlet and the analysis chamber and forming a portion of the reagent chamber such that flexion of
