Lymphangioleiomyomatosis: circulating levels of FGF23 and pulmonary diffusion [PDF]
Jornal Brasileiro de Pneumologia, 2023 Objective: Lymphangioleiomyomatosis (LAM) is a rare, destructive disease of the lungs with a limited number of determinants of disease activity, which are a critical need for clinical trials.

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.

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.

European Respiratory Journal, 2018 The aim of this study was to determine reference equations for the combined measurement of diffusing capacity of the lung for carbon monoxide (CO) and nitric oxide (NO) (DLCONO). In addition, we wanted to appeal for consensus regarding methodology of the

Heritability and genome-wide association study of diffusing capacity of the lung
European Respiratory Journal, 2018 Although several genome-wide association studies (GWAS) have investigated the genetics of pulmonary ventilatory function, little is known about the genetic factors that influence gas exchange.

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
