Journal ArticleDOI
A review of the volatiles from the healthy human body
B P J de Lacy Costello,Anton Amann,Anton Amann,Huda Al-Kateb,C. Flynn,Wojciech Filipiak,Wojciech Filipiak,T Khalid,D. Osborne,Norman M. Ratcliffe +9 more
TL;DR: A compendium of all the volatile organic compounds (VOCs) emanating from the human body (the volatolome) is for the first time reported and it is the authors' intention that this database will not only be a useful database of VOCs listed in the literature, but will stimulate further study of V OCs from healthy individuals.
Journal ArticleDOI
The human volatilome: volatile organic compounds (VOCs) in exhaled breath, skin emanations, urine, feces and saliva
Anton Amann,Anton Amann,Ben de Lacy Costello,Wolfram Miekisch,Jochen K. Schubert,Bogusław Buszewski,Joachim D. Pleil,Norman M. Ratcliffe,Terence H. Risby +8 more
TL;DR: In future studies, combined investigations of a particular compound with regard to human matrices such as breath, urine, saliva and cell culture investigations will lead to novel scientific progress in the field.
Journal ArticleDOI
Fecal microbiome and volatile organic compound metabolome in obese humans with nonalcoholic fatty liver disease
Maitreyi Raman,Iftikhar Ahmed,Patrick M. Gillevet,Chris Probert,Norman M. Ratcliffe,S. Smith,Rosemary Greenwood,Masoumeh Sikaroodi,Victor Lam,Pam Crotty,Jennifer Bailey,Robert P. Myers,Kevin P. Rioux +12 more
TL;DR: A significant increase in fecal ester VOC is associated with compositional shifts in the microbiome of obese NAFLD patients, and these novel bacterial metabolomic and metagenomic factors are implicated in the etiology and complications of obesity.
Journal ArticleDOI
Volatile organic compounds from feces and their potential for diagnosis of gastrointestinal disease
C.E. Garner,S. Smith,B P J de Lacy Costello,Paul D. White,R. Spencer,Chris Probert,Norman M. Ratcliffe +6 more
TL;DR: Findings in this work could lead the way to the development of a rapid diagnostic device based on VOC detection for gastrointestinal disease diagnosis.
Journal ArticleDOI
The importance of methane breath testing: a review
TL;DR: The combined measurement of hydrogen and methane should offer considerable improvement in the diagnosis of malabsorption syndromes and SIBO when compared with a single hydrogen breath test.
