The α-emitting radionuclide radium-223 (Ra) is widely used for the treatment of bone metastasis in patients with castration-resistant prostate cancer. However, Ra decays into radon-219 (Rn) which is a noble-gas isotope, and Rn may escape from patients treated with Ra via their respiration. In this study, we quantified the amount of Rn contained in the breath of patients treated with Ra to estimate its effect on the internal exposure dose of caregivers.

The analysis of volatile organic compounds (VOCs) within exhaled breath potentially offers a non-invasive method for the detection and surveillance of human disease. Oral contamination of exhaled brea...
Real time measurements of the differences in inhaled and exhaled normal and fully deuterated acetone concentration levels at rest and during exercise have been conducted using proton transfer reaction...
New insight into the omic sciences suggests that volatile organic compounds (VOCs) contained in exhaled breath can reflect the healthy or disease state of patients, representing an attractive, promisi...
Current anti-doping testing is primarily conducted in urine and blood. Recently, due to confounding factors with urine and blood collections such as invasiveness, cost, and stringent shipping conditio...
Lung adenocarcinoma is characterized by poor prognosis and short survival rates. Therefore, tools to identify the tumoural molecular structure and guide effective diagnosis and therapy decisions are e...
Given the possible prognostic relationship between exhaled breath condensate pH and clinical symptoms, it is quite plausible that exhaled breath condensate pH can prove useful in the inten...
Cross sectional case-control study investigating the difference of volatile organic compound in the exhaled breath of the patients with GI bleeding and normal population.
This is a prospective pilot study investigating exhaled breath condensate analyses to quantify the variability over time of various biomarkers associated with symptomatic pneumonitis.
The purpose of this study is to detect a specific profile of breath in healthy subjects by an untargeted metabolomic study using exhaled breath analysis by mass soectrometry.
Carbon-12 and carbon-13 are naturally-abundant isotopes in exhaled breath carbon dioxide. The ratio of carbon-13 to carbon-12 in exhaled breath is known as the breath delta value. This stu...

Measurement of radioactivity in the entire human body.
Qualitative and quantitative measurement of MOVEMENT patterns.
A diagnostic test in which vitamin B12 is tagged with radioactive cobalt, taken orally, and gastrointestinal absorption is determined via measurement of the amount of radioactivity in a 24-hour urine collection.
