The aim of this work was to investigate volatile organic compounds (VOCs) emanating from urine samples to determine whether they can be used to classify samples into those from prostate cancer and non-cancer groups. Participants were men referred for a trans-rectal ultrasound-guided prostate biopsy because of an elevated prostate specific antigen (PSA)(More)
Volatiles from infusions of lemon basil Ocimum citriodorum Vis were evaluated by SPME-GC/MS. Citral, linalool and estragole were the major constituents. Citral, the major contributor to the lemony flavour, was significantly higher in post-flowering (79%) and full-flowering (65%), it was reduced to 42% at pre-flowering. Linalool was consistent throughout the(More)
Analysis of volatile organic compounds (VOCs) from saliva, to aid disease diagnoses, has received little attention. This work aims to address the paucity of information on saliva volatiles and includes a database of newly identified compounds whilst incorporating a review of the literature. The volatile constituents in the headspace of whole saliva obtained(More)
A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported. 1840 VOCs have been assigned from breath (872), saliva (359), blood (154), milk (256), skin secretions (532) urine (279), and faeces (381) in apparently healthy individuals. Compounds were assigned CAS registry numbers and(More)
Steroids metabolism plays an important role in mammals and contributes to quality of pig meat. The main objective of this study was to identify metabolites of androstenone, 17β-estradiol and dihydrotestosterone using primary cultured pig hepatocytes as a model system. The role of 3β-hydroxysteroid dehydrogenase (3βHSD) in regulation of steroid metabolism(More)
