Volatile organic compounds (VOCs) are low molecular weight (<1 kDa) compounds which represent the final products of cell metabolism. Their composition can be affected by several factors including diet, hormones, environment and the presence of diseases, in particular, cancer.
Endogenous breath VOCs
Inflammatory bowel disease (IBD) is a growing and significant problem in childhood. The diagnosis and monitoring of IBD in children is highly invasive and is accompanied by risk, stress/anxiety for children and families and significant use of healthcare resources. Children, young people and families
Physicians in ancient Greece understood that smelling the breath of their patients can assist in diagnosis. However, while this rather primitive diagnostic method hasn't changed much over the centuries, there has been an increasing interest in recent years in improving methods of noninvasive early
Worldwide there are 130 000 new larnx cancers diagnosed annually resulting in 82 000 deaths.Survival after diagnosis of larynx cancer depends on initial stage. For T3N0Mo laryngeal cancers 5-year survival ranges from 59 to 66%. Patients survivals are as follows: receiving either chemoradiation
Cancer is accompanied by increased oxidative stress and induction of polymorphic cytochrome P- 450 mixed oxidase enzymes (CYP). Both processes affect the abundance of volatile organic compounds (VOCs) in the breath because oxidative stress causes lipid peroxidation of polyunsaturated fatty acids in
The Effects of N-Acetylcysteine on Oxidative Stress in Chronic Hepatitis C
Objective:
There is evidence that suggests oxidative stress plays a role in the pathologic mechanism of disease progression in chronic hepatitis C virus infection (HCV). This study will test the hypothesis that
