Methods are described herein for small molecule biochemical profiling of an individual subject for diagnosis of a disease or disorder, facilitating diagnosis of a disease or disorder, and/or identifying an increased risk of developing a disease or disorder in the individual subject. Aberrant levels of small molecules present in a sample from an individual subject are identified and diagnostic information relevant to the individual subject is obtained based on the identified aberrant levels. The obtained diagnostic information includes one or more of an identification of at least one biochemical pathway associated with the identified subset of the small molecules having aberrant levels, an identification at least one disease or disorder associated with the identified subset of the small molecules having aberrant levels, and an identification of at least one recommended follow up test associated with the identified subset of the small molecules having aberrant levels.


A method, apparatus, and computer-readable storage medium for analyzing sample data from a component separation/mass spectrometer system. A profile plot is formed for each sample, each having retention time and intensity axes, the intensity being represented as a function of retention time for a selected sample ion mass. An intensity peak arrangement, including at least one identifying peak, each having a peak range and characteristic intensity, is identified for a selected ion in the profile plot for each sample. An orthogonal plot, corresponding to the profile plot, for each sample is formed, extending along the retention time axis perpendicularly to the intensity axis. The characteristic intensity of each of the at least one identifying peak is represented on the retention time axis of the orthogonal plot with gradated indicia.


Methods are provided for synthesizing mixtures of lipids that are representative of the structural diversity of the lipids present in samples of interest. The complex mixtures of lipids produced according to the methods of the present disclosure can be used as internal standards for detecting and quantifying the lipids in samples of interest. Kits including the internal standards and instructions for their use in the detection and quantification of lipids in samples of interest are also provided.

Type 2 diabetes (T2DM) is preventable by sustained changes in diet and physical exercise. Despite this, modern societies are already approaching 10% population prevalence of diabetes, and another 15% with pre-diabetes. The costs of T2DM are huge, approaching 10% of all health costs. Prevention of diabetes is a priority for national healthcare agencies and for the health insurance industry. Investment in prevention and lifestyle programmes requires a solid evidence-base for targeting and customising these interventions in a cost-effective manner. Translation of the findings from T2DM prevention studies to the benefit of general public health has not yet been possible. DEXLIFE will identify novel diagnostic and predictive biomarkers (i) to detect the progression toward diabetes in high risk individuals and (ii) that are responsive to lifestyle interventions known to be effective in diabetes prevention. New biomarkers alone will be insufficient to alter the course of diabetes progression. We bring a strong translational focus to this proposal, by setting the main intervention in the real-life context of a major health insurance system. The accumulated phenotyping repertoire from an extensive panel of omic analyses will be refined and modelled into a new diagnostic panel for the allocation of high risk subjects to individualised preventive regimens. Our multi-disciplinary team has a strong track record in clinical diabetes and metabolism. Several unique clinical cohorts will provide the basis for a series of clinical, physiological and mechanistic investigations, which will identify, monitor and analyse the impact of biomarkers over time. An exercise and dietary intervention study will be included in two specific cohorts, enabling us to assess the impact of such interventions on plasma biomarkers and functional tissue-based markers. Project clinical and industry partners will support the translation of our findings into clinical practice.
