Application of short-term inhalation studies to assess the inhalation toxicity of nanomaterials
Particle and Fibre Toxicology, 2014 BackgroundA standard short-term inhalation study (STIS) was applied for hazard assessment of 13 metal oxide nanomaterials and micron-scale zinc oxide.MethodsRats were exposed to test material aerosols (ranging from 0.5 to 50 mg/m3) for five consecutive ...

Specific inhalation challenge in the diagnosis of occupational asthma: consensus statement
European Respiratory Journal, 2014 This consensus statement provides practical recommendations for specific inhalation challenge (SIC) in the diagnosis of occupational asthma. They are derived from a systematic literature search, a census of active European centres, a Delphi conference ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes
