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.

Dual test gas pulmonary diffusing capacity in patients with idiopathic scoliosis 40 years after diagnosis. [PDF]

Exp Physiol
There is limited knowledge on diffusing capacity in scoliosis patients. It remains to be determined if impaired pulmonary diffusing capacity is mostly influenced by reduced alveolar–capillary membrane diffusing capacity (DM, CO), reduced pulmonary ...

Alveolar-membrane diffusing capacity limits performance in Boston marathon qualifiers. [PDF]

PLoS ONE, 2012
PURPOSE: (1) to examine the relation between pulmonary diffusing capacity and marathon finishing time, and (2), to evaluate the accuracy of pulmonary diffusing capacity for nitric oxide (DLNO) in predicting marathon finishing time relative to that of ...

Lung diffusing capacity for nitric oxide in space: microgravity gas density interactions. [PDF]

Front Physiol, 2023
Introduction: During manned space exploration lung health is threatened by toxic planetary dust and radiation. Thus, tests such as lung diffusing capacity (DL) are likely be used in planetary habitats to monitor lung health. During a DL maneuver the rate

Value of lung diffusing capacity for nitric oxide in systemic sclerosis [PDF]

Physiological Reports, 2019
A decreased lung diffusing capacity for carbon monoxide (DLCO) in systemic sclerosis (SSc) is considered to reflect losses of alveolar membrane diffusive conductance for CO (DMCO), due to interstitial lung disease, and/or pulmonary capillary blood volume

Reference values for lung function tests: III. Carbon monoxide diffusing capacity (transfer factor) [PDF]

Brazilian Journal of Medical and Biological Research, 1999
Carbon monoxide diffusing capacity (DLCO) or transfer factor (TLCO) is a particularly useful test of the appropriateness of gas exchange across the lung alveolocapillary membrane. With the purpose of establishing predictive equations for DLCO using a non-

Pulmonary diffusing capacity for carbon monoxide and nitric oxide after COVID-19: A prospective cohort study (the SECURe study). [PDF]

Exp Physiol
Many patients exhibit persistently reduced pulmonary diffusing capacity after coronavirus disease 2019 (COVID‐19). In this study, dual test gas diffusing capacity for carbon monoxide and nitric oxide (DL,CO,NO) metrics and their relationship to disease ...

Mapping EQ5D utilities from forced vital capacity and diffusing capacity in fibrotic interstitial lung disease. [PDF]

PLoS One, 2023
ObjectivesFibrotic interstitial lung disease (ILD) includes a large group of conditions that lead to scarring of the lungs. The lack of available 5-level EuroQol 5D (EQ5D) data has limited the ability to conduct economic evaluations in ILD.
