Volatile Organic Compounds

01/01/2013 - "We have tested the efficacy of a new method to identify BAD, based on the detection of differences in volatile organic compounds (VOC) in urine headspace of BAD vs. ulcerative colitis and healthy controls. "
08/01/2011 - "Our group has characterized the VOCs (volatile organic compounds) in the headspace gas emitted from faecal samples from healthy subjects, from patients with infectious diarrhoea and from those with Crohn's disease or ulcerative colitis, both in relapse and remission. "

04/01/2003 - "With increasing interest in the detection of disease-related volatile organic compounds (VOCs) found in human breath, breath analysis could prove to be a very useful diagnostic tool, especially for the early detection of lung cancer. "
05/01/2015 - "The colorimetric sensor array signature of exhaled breath volatile organic compounds was capable of distinguishing patients with lung cancer from clinically relevant control subjects in a discovery level trial. "
01/01/2015 - "Results collected in more than 20 years of studies suggest a relationship between the volatile organic compounds exhaled in breath and lung cancer. "
09/01/2014 - "Early studies done by mass spectrometry show that volatile organic compounds from human breath can represent certain disease states of our bodies, such as lung cancer, and revealed the potential of breath analysis. "
02/15/2014 - "Few studies have investigated associations between nonoccupational exposure to ambient volatile organic compounds and lung cancer. "

06/01/1995 - "Improved indoor environment can also be achieved by selecting building materials, building construction, and indoor activities on the principle that the emission of volatile organic compounds should be as low as reasonably achievable, to minimise symptoms related to asthma due to indoor air pollution."
08/01/2007 - "The purpose of this study was to analyze association between exposure to volatile organic compounds (VOC) and asthma in adults. "
01/01/2004 - "Observational studies have consistently found a relation between volatile organic compounds and indicators of asthma, such as symptoms, peak flows, and objectively measured bronchial reactivity. "
08/01/2002 - "The specific volatile organic compounds (VOCs) identified in association with occupational asthma are generally not the same as those in studies showing respiratory effects of VOC mixtures on nonoccupational adult and pediatric asthma. "
06/01/2015 - "Volatile organic compounds (VOCs) are one of the aggravating factors of asthma and other allergic diseases. "

09/01/2012 - "Exhaled volatile organic compounds (VOCs) have shown promise in diagnosing chronic obstructive pulmonary disease (COPD) but studies have been limited by small sample size and potential confounders. "
01/01/2015 - "The purpose of this study was to investigate whether volatile organic compounds (VOCs) could be detected in the exhaled breath of patients with COPD and whether these VOCs could distinguish COPD patients from healthy subjects. "
01/01/2015 - "Exhaled volatile organic compounds discriminate patients with chronic obstructive pulmonary disease from healthy subjects."
01/01/2014 - "Short-Term Intra-Subject Variation in Exhaled Volatile Organic Compounds (VOCs) in COPD Patients and Healthy Controls and Its Effect on Disease Classification."
09/01/2012 - "Machine learning methods on exhaled volatile organic compounds for distinguishing COPD patients from healthy controls."

01/01/2015 - "The efficacy of breath volatile organic compounds (VOCs) analysis for the screening of patients bearing breast cancer lesions has been demonstrated by using gas chromatography and artificial olfactory systems. "
10/01/2012 - "This study aims to verify the existence of specific volatile organic compounds (VOCs) in the breath of breast cancer patients. "
10/01/2012 - "Volatile organic compounds (VOCs) in exhaled breath of patients with breast cancer in a clinical setting."
06/01/2011 - "We are investigating the utility of the analysis of breath volatile organic compounds (VOCs) as an effective modality for breast cancer (BC) detection and monitoring by collecting breath samples with a simple portable device to determine whether BC patients have breath VOCs distinct from those in healthy volunteers. "
09/01/2006 - "We evaluated a breath test for volatile organic compounds (VOCs) as a predictor of breast cancer. "
