The effects of lung volume reduction treatment on diffusing capacity and gas exchange

European Respiratory Review, 2020
Lung volume reduction (LVR) treatment in patients with severe emphysema has been shown to have a positive effect on hyperinflation, expiratory flow, exercise capacity and quality of life.

Heterogeneous pattern of differences in respiratory parameters between elderly with either good or poor FEV1

BMC Pulmonary Medicine, 2018
Background The relationship of spirometric values to other respiratory and functional parameters in advanced age is not well studied. We assessed this relationship in elderly subjects with either good or poor spirometric parameters to reveal whether ...

Mechanisms of gas transfer impairment utilizing nitric oxide following severe COVID‐19 pneumonitis

Physiological Reports, 2023
Reduced carbon monoxide diffusing capacity (DLCO) is common after recovery from severe COVID‐19 pneumonitis. The extent to which this relates to alveolar membrane dysfunction as opposed to vascular injury is uncertain.

Convergence of diffusion with concentrating capacity

Journal of Mathematical Analysis and Applications, 1989
AbstractThe diffusion of electric charge on a thin-film dielectric is described by an initial-boundary-value problem for a parabolic partial differential equation on a planar region. Consider the situation where conductivity on a given subregion increases to large values and the corresponding limiting problem has the total capacitance of that subregion

Capacity of discrete molecular diffusion channels [PDF]

2011 IEEE International Symposium on Information Theory Proceedings, 2011
In diffusion-based molecular communications, messages can be conveyed via the variation in the concentration of molecules in the medium. In this paper, we intend to analyze the achievable capacity in transmission of information from one node to another in a diffusion channel. We observe that because of the molecular diffusion in the medium, the channel

Carrying Capacity of a Population Diffusing in a Heterogeneous Environment

Mathematics, 2020
The carrying capacity of the environment for a population is one of the key concepts in ecology and it is incorporated in the growth term of reaction-diffusion equations describing populations in space.

RITUXIMAB TREATMENT FOR INTERSTITIAL LUNG INJURY IN SCLERODERMA SYSTEMATICA

Научно-практическая ревматология, 2013
Objective: to study the efficiency and tolerance of rituximab (RTM) treatment in patients with scleroderma systematica (SDS) with interstitial lung injury (ILI).Subjects and methods. The trial included 27 patients (26 women and 1 man) (mean age 45.7±13.0

Combined diffusing capacity for nitric oxide and carbon monoxide as predictor of bronchiolitis obliterans syndrome following lung transplantation

Respiratory Research, 2018
Background There is a need for non-invasive parameters that are sensitive to the development of the bronchiolitis obliterans syndrome (BOS) in lung transplantation (LTx) patients.

Absolute lung size and the sex difference in breathlessness in the general population. [PDF]

PLoS ONE, 2018
Breathlessness is associated with major adverse health outcomes and is twice as common in women as men in the general population. We evaluated whether this is related to their lower absolute lung volumes.Cross-sectional analysis of the population-based ...
