Non‐Invasive Diagnosis of Hypertrophic Cardiomyopathy by Breath

Advanced Sensor Research, Volume 4, Issue 7, July 2025.
The use of sensor technologies for the diagnosis of hypertrophic cardiomyopathy (HCM) by identification of volatile organic compounds (VOCs) in breath samples. By combining gas chromatography‐mass spectrometry (GC‐MS) and electronic nose (eNose) platforms, specific VOC patterns associated with HCM are detected and analyzed.

The Effect of Grain Size on Radon Exhalation Rate in Natural-dust and Stone-dust Samples [PDF]

, 2015
Radiation dose to human population due to inhalation of radon and its progeny contributes more than 50% of the total dose from the natural sources which is the second leading cause of lung cancer after smoking. In the present work the dependence of radon

RADON EXHALATION FROM BUILDING MATERIALS USED IN YEMEN

Radiation Protection Dosimetry, 2018
The present article seeks to determine the annual effective doses of 222Rn exposure, effective radium content and radon exhalation rates in some building materials from the local market of Ibb province, Yemen. A total of 33 samples of building materials were collected from the target area. The radon exhalation rate and effective radium content in these

Re‐assessment of the risks to public health related to the genotoxicity of styrene present in plastic food contact materials

EFSA Journal, Volume 23, Issue 6, June 2025.
Abstract The EFSA Panel on Food Contact Materials (FCM) was requested by the European Commission to re‐evaluate the potential genotoxicity of styrene after oral exposure and its safety for use in plastic FCM with a specific migration limit (SML) of 40 μg/kg food.

Functional Lung Imaging Identifies Peripheral Ventilation Changes in ꞵ‐ENaC Mice

Respirology, Volume 30, Issue 4, Page 335-345, April 2025.
β‐ENaC‐Tg mice have previously been shown to exhibit muco‐obstructive disease and emphysema. This study analysed lung function in β‐ENaC‐Tg mice using XV functional imaging and flexiVent assessments. XV enabled ventilation defects to be identified and localised, and the flexiVent comfirmed increased lung compliance and reduced tissue elastance ...
