Abstract: The invention relates to a composition, in particular to an oral anti-ageing composition for treating hair ageing. This invention is based on the observation that the combination of hesperetin, a flavanone, derivable from a natural rutinoside hesperetin 7-rutinoside (also known as hesperidin) in citrus, e.g., in Citrus aurantium L, Citrus sinensis, Zanthozylum gilletti, leaves of Agathosma serratifolia, and trans-resveratrol synergistically up-regulates NQO-1 in a gene expression assay. The combination also induces Glo1, decreases MG and MG-protein glycation, decreases insulin resistance, decreases fasting plasma glucose, induces modest weight loss, improves renal function, decreases vascular inflammation marker slCAM-1, improves arterial dilatation and decreases the risk of cardiovascular disease.

Abstract: The present invention provides methods for diagnosing an autistic spectrum disorder (ASD), comprising detecting the concentration of an amino acid adduct in a sample obtained from a subject, wherein said amino acid adduct is a glycated amino acid adduct, an oxidised amino acid adduct, or a nitrated amino acid adduct. Methods of the invention further comprise comparing the concentration of the amino acid adduct in the sample with the concentration of the same amino acid adduct in a reference standard; and identifying the presence or absence of a concentration difference of said amino acid adduct in the sample relative to the reference standard; wherein the presence or absence of a concentration difference correlates with the presence or absence of ASD. Diagnostic algorithms for use in methods of the invention are also provided.

Abstract: The disclosure relates to a fluorescence based assay for the detection of alpha, beta-dicarbonyl containing compounds, for example alpha-oxoaldehyde compounds such as glyoxal, methylglyoxal, hydroxypyruvaldehyde, erythrosone, 3-deoxy-erythrosone, ribosone, 3-deoxyribosone, glucosone, 3-deoxyglucosone and stereoisomers thereof and butan-2,3-dione that uses a fluorogenic probe which is stable under ambient conditions. The fluorogenic probes comprise a 1,2-diaminophenyl moiety. The diaminophenyl probes yield a 20-fold increase in quantum yield when they are a derivative of fluorescein (DAF), rhodamine (DAR), BODIPY or cyanine. The assay is preferably carried out at pH 4-8. Corresponding screening methods for modulators of alpha, beta-dicarbonyl compound concentrations are also disclosed.

Abstract: The invention concerns the role of Glo 1 in the prevention and reversal of proteomic and genomic damage by carbonyl substrates thereof and, in particular, therapeutics that promote Glo 1 production.
