Abstract: The present invention is directed to a method for differentially diagnosing dementia or the risk of dementia in a patient. The method comprises obtaining a sample from the patient; analyzing the sample to obtain quantifying data for one or more than one metabolite marker; comparing the quantifying data for the one or more than one metabolite marker to corresponding data obtained from one or more than one reference sample; and using the comparison to differentially diagnose dementia or the risk of dementia. The method may also assis in assessing dementia or the risk of dementia in a patient. The present invention is also directed to metabolite markers and compounds useful in the present method.

Abstract: A novel method and apparatus for Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FTICR-MS). The FTICR-MS apparatus has a pre-ICR mass separation and filtering device capable of receiving ionized molecules with a plurality of mass to charge (M/Z) sub-ranges. The pre-ICR mass separation and filtering device divides the ionized molecules into a plurality of smaller packets, each of the smaller packets is within one of the M/Z sub-ranges. A magnet in the FTICR-MS apparatus provides a controlled magnetic field. A plurality of ion cyclotron resonance (ICR) cells are arranged in series in the controlled magnetic field and operate independently. An ion trapping device connects the pre-ICR mass separation and filtering device, and stores one of the plurality of smaller packets, prior to sending it to one of the plurality of ICR cells.

Abstract: The present invention relates to the diagnosis of colorectal and ovarian cancers (CRC and OC, respectively). The present invention describes the relationship between endogenous small molecules and CRC or OC. Specifically, the present invention relates to the diagnosis of CRC and OC through the measurement of vitamin E isoforms and related metabolites. The present invention also relates to diagnostic markers identified in said method. The present invention relates to the underlying case and pre-symptomatic phases of CRC, the diagnosis of various stages and severity of CRC, the early detection of CRC, monitoring and diagnosing the effect of therapy on CRC and OC health states.

Abstract: The invention can be summarized as follows.

Abstract: A method for non-targeted complex sample analysis which involves the following steps. A first step involves providing a database (16) containing identifying data of known molecules. A second step involves introducing a complex sample containing multiple unidentified molecules into a Fourier Transform Ion Cyclotron Mass Spectrometer (12) to obtain data regarding the molecules in the complex sample. A third step involves comparing the collected data regarding the molecules in the complex sample with the identifying data of known molecules in order to arrive at an identification through comparison of the molecules in the sample.
