Abstract:
Peptide-lipid constructs of the structure L-S-F are disclosed, where F is a peptide, S is a spacer covalently linking F to L via an oligomer of ethylene glycol, and L is a diacyl- or dialkyl-glycerolipid (including glycerophospholipids). The spacer ideally has 6 to 14 ethylene glycol repeats, corresponding to PEG with a molecular weight of approximately 250 to 600. Also disclosed is a method of detecting reactive antibodies in serum by contacting serum with cells modified to incorporate a peptide-lipid construct, where the peptide is an epitope of the antibody, and determining the degree of agglutination of the cells.
Abstract:
Methods for the diagnosis, risk assessment, and monitoring of Autism Spectrum Disorder (ASD) are disclosed. More specifically the present invention relates to the measurement of small molecules (metabolites) in human plasma that are found to have different abundances between persons with a clinical manifestation of ASD and subjects not expressing symptoms of ASD. Further, this invention relates to the monitoring of putative therapeutic strategies designed to ameliorate the biochemical abnormalities associated with ASD.
Abstract:
The present invention provides a mass spectrometry-based method of identifying a cancer marker in sera and uses of said cancer marker in diagnosing cancer in human and non-human subjects. The invention further provides isolated cancer markers.
Abstract:
Disclosed is a method of diagnosing a neuralgic or neuritic condition in a subject, the method comprising the steps of : obtaining a sample of body fluid from the subject having a suspected neuralgic or neuritic condition; and testing the sample for the presence of antibodies reactive with a bacterial antigen; diagnosis of a neuralgic or neuritic condition being made where the sample from the patient contains a concentration of said antibodies above a pre-determined level.
Abstract:
Disclosed is a method for detecting the presence, progression or risk of onset of neurodegenerative disease, based on determination of the concentration of lipid markers in an individual's serum or plasma sample.
Abstract:
The present invention relates to methods of treating neurodegenerative disorders associated with Alzheimer's disease (AD), Parkinson's disease (PD) and synucleinopathies, such as dementia with Lewy bodies, Down Syndrome (DS) and associated cognitive disorders, multiple system atrophy, and rare neuroaxonal dystrophies, such as Niemann-Pick type C disease (NPC) and Gaucher' s disease comprising administering an inhibitor to disrupt the interaction between Αβ or aS and neuronal lipids. The invention further relates to assays for identifying agents that reduce interaction between Αβ or aS and neuronal lipids. Lastly, the invention relates to methods and compositions for intranasal administration of fatty acids or lipids containing fatty acid acyl chains of dietary lipids for promoting central nervous system health and/or prevention or treatment of neurodegenerative disorders.
Abstract:
The present invention is related to a method for diagnosing Farber's disease in a subject, wherein the method comprises detecting C26 ceramide in a sample from the subject.
Abstract:
The present disclosure provides methods and systems for detecting melanoma in a host. The methods include non-invasive methods of detecting melanoma and methods and systems for providing a molecular signature and/or melanoma biomarker signature for a host.
Abstract:
A method is disclosed comprising obtaining or acquiring chemical or other non- mass spectrometric data from one or more regions of a target (2) using a chemical sensor (20). The chemical or other non-mass spectrometric data may be used to determine one or more regions of interest of the target (2). An ambient ionisation ion source 1 may then be used to generate aerosol, smoke or vapour (5) from one or more regions of the target (2).
