Breath volatile analysis from patients diagnosed with harmful drinking, cirrhosis and hepatic encephalopathy: A pilot study (2013)
Journal Article

Hepatic encephalopathy (HE) is a neuropsychiatric state potentially complicating cirrhosis following the accumulation of toxic compounds that cross the blood-brain barrier and affect brain function; the compounds may undergo alveolar gas exchange and...

An investigation of volatile organic compounds from the saliva of healthy individuals using headspace-trap/GC-MS (2013)
Journal Article

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...

The Development of Novel Fuel Dehydrating Icing Inhibitors (2013)
Journal Article

Dissolved water is a normal component of jet fuel which is vapourised during combustion; however, free water is a contaminant that can starve engines, freeze to form ice crystals capable of blocking fuel feeds, support microbial growth, and contribut...

A Pilot Study Combining a GC-Sensor Device with a Statistical Model for the Identification of Bladder Cancer from Urine Headspace (2013)
Journal Article

There is a need to reduce the number of cystoscopies on patients with haematuria. Presently there are no reliable biomarkers to screen for bladder cancer. In this paper, we evaluate a new simple in-house fabricated, GC-sensor device in the diagnosis...

The importance of methane breath testing: A review (2013)
Journal Article

Sugar malabsorption in the bowel can lead to bloating, cramps, diarrhea and other symptoms of irritable bowel syndrome as well as affecting absorption of other nutrients. The hydrogen breath test is now a well established noninvasive test for assessi... Read More about The importance of methane breath testing: A review.

The use of MS for the investigation of irritable bowel syndrome and inflammatory bowel disease (2013)
Journal Article

Currently, the diagnosis of bowel diseases such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) relies on invasive and expensive procedures. Identification of biomarker-based tests to aid diagnosis is an important area of resea... Read More about The use of MS for the investigation of irritable bowel syndrome and inflammatory bowel disease.

Volatile organic compounds (VOCs) found in urine and stool (2013)
Book Chapter

An Investigation of Fecal Volatile Organic Metabolites in Irritable Bowel Syndrome (2013)
Journal Article

Diagnosing irritable bowel syndrome (IBS) can be a challenge; many clinicians resort to invasive investigations in order to rule out other diseases and reassure their patients. Volatile organic metabolites (VOMs) are emitted from feces; understanding... Read More about An Investigation of Fecal Volatile Organic Metabolites in Irritable Bowel Syndrome.

Volatiles from oral anaerobes confounding breath biomarker discovery (2013)
Journal Article

The levels of compounds in exhaled mouth air do not necessarily reflect levels in the systemic circulation as bacteria can bio-transform substrates to produce compounds within the mouth. This should be of concern to researchers measuring breath volat... Read More about Volatiles from oral anaerobes confounding breath biomarker discovery.

Fecal microbiome and volatile organic compound metabolome in obese humans with nonalcoholic fatty liver disease (2013)
Journal Article

BACKGROUND & AIMS: The histopathology of nonalcoholic fatty liver disease (NAFLD) is similar to that of alcoholic liver disease. Colonic bacteria are a source of many metabolic products, including ethanol and other volatile organic compounds (VOC) th...
