VENTILATION HETEROGENEITY IN THE ACINAR AND CONDUCTIVE ZONES OF THE NORMAL AGEING LUNG Online Supplement
1. Principle and computation of Sacin and Scond from phaseIII slope analysis : The MBW normalized slope analysis technique identifies the various mechanisms of ventilation heterogeneity generating a phaseIII slope, attributing these to either the conductive airways (where convection predominates) or the acinar air spaces (where diffusion and convection interact). In the conductive lung zone, a ...
متن کاملInvestigation of lung normal tissue doses in lung tumors radiation therapy using both gated and conventional radiotherapy
Introduction: In radiation therapy of lung tumors, respiratory motion causes target moving, so a larger margin is needed to cover the clinical target volume (CTV). With the margin increasing, a larger volume of normal tissue will be exposed to high-dose. In this study, dosimetric parameters of normal lung tissue were compared between gated and conventional radiotherapy (RT), u...
متن کاملVentilation heterogeneity in the acinar and conductive zones of the normal ageing lung.
RATIONALE Small airways function studies in lung disease have used three promising multiple breath washout (MBW) derived indices: indices of ventilation heterogeneity in the acinar (S(acin)) and conductive (S(cond)) lung zones, and the lung clearance index (LCI). Since peripheral lung structure is known to change with age, ventilation heterogeneity is expected to be affected too. However, the a...

متن کاملEvaluation of silica nanoparticles cytotoxicity (20-40 nm) on cancerous epithelial cell (A549) and fibroblasts cells of human normal lung fibroblast (MRC5)
Introduction: Silica nanoparticles have received more attraction in medical and industrial applications due to their unique properties such as small size, the possibility of surface functionalization, ease of production, and low cost. So, it is necessary to study the respiratory toxicity of occupational exposure due to the production and increasing use of silica nanoparticles, especially in the...
