Abstract: Provided herein is a method for determining a metabolic state of a plant or part thereof comprising a) rapid evaporating a multitude of metabolites of said plant or part thereof; b) determining the amount of at least one metabolite characteristic of said metabolic state; and c) thereby, determining a metabolic state of a plant thereof. Further provided is a method for in vivo determining a metabolite distribution in a plant or part thereof comprising a) in vivo rapid evaporating at least one metabolite of interest in at least a first and a second location of said plant or part thereof; b) determining the amounts of at least one metabolite at said first and a second location; and, c) thereby, in vivo determining metabolite distribution in a plant or part thereof. Moreover, provided are devices, data collections, and uses relating to the aforesaid methods.

Abstract: The present invention relates to the field of diagnostic methods. Specifically, the present invention contemplates a method for diagnosing a cardiac disease in a subject based on determining the amounts of at least three lipid metabolite biomarkers and at least one further cardiac biomarker. The invention also relates to tools for carrying out the aforementioned methods, such as diagnostic devices.

Abstract: The present invention relates to diagnostic means and methods for heart failure. In particular, the invention relates to a method for diagnosing heart failure in a subject suspected to suffer therefrom comprising determining the amount of at least one cholesterol parameter and/or total sphingomyelins and/or triacylglycerols in a sample of the said subject, and comparing the amount(s) determined in step (a) to a reference, whereby it is diagnosed whether the subject suffers from heart failure, or not. Moreover, the invention pertains to a device for diagnosing whether a subject suffers from heart failure, or not, and to the use, in general, of enzymatic detection agents for at least one cholesterol parameter and/or total sphingomyelins and/or triacylglycerols for diagnosing in a sample of a subject whether the said subject suffers from heart failure, or not. Finally, contemplated is a kit for diagnosing heart failure in subject suspected to suffer therefrom.
