Predictors of Diffusing Capacity in Children With Sickle Cell Disease: A Longitudinal Study

open access: yesFrontiers in Pediatrics, 2021
Background: Gas exchange abnormalities in Sickle Cell Disease (SCD) may represent cardiopulmonary deterioration. Identifying predictors of these abnormalities in children with SCD (C-SCD) may help us understand disease progression and develop informed ...

Optimization in First-Passage Resetting

open access: yes, 2020
We investigate classic diffusion with the added feature that a diffusing particle is reset to its starting point each time the particle reaches a specified threshold.

Recommendations for the use of endoscopic lung volume reduction in South Africa: Role in the treatment of emphysema [PDF]

open access: yes, 2015
Emphysema is a very common cause of morbidity and mortality in South Africa (SA). Therapeutic options in severe emphysema are limited. Endoscopic lung volume reduction (ELVR) is increasingly being used internationally for the treatment of advanced ...

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Postural variation of pulmonary diffusing capacity as a marker of lung microangiopathy in Indian patients with type 2 diabetes mellitus

open access: yesIndian Journal of Endocrinology and Metabolism, 2016
Introduction: Diabetes mellitus (DM) is characterized by the presence of chronic hyperglycemia and formation of advanced glycation end products (AGEs). Interaction between AGE and its receptor leads to endothelial damage and microangiopathy.

Diffusing capacity in acute untreated tropical eosinophilia [PDF]

open access: yes, 1988
Single breath carbon monoxide diffusing capacity (TLCO) measurements were made in 50 acute untreated tropical eosinophilia (TE) patients. Forty-four (38%) patients had a low diffusing capacity (< 85% predicted) which was moderately severe (40- 70 ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Approximation of diffuse measures for parabolic capacities

open access: yesComptes Rendus. Mathématique, 2008
Given a parabolic cylinder Q = (0, T) x Omega, with Omega subset of R-N, we consider the class of finite measures which do not charge sets of zero p-parabolic capacity in Q. We prove that such measures can be strongly approximated by measures which can be written as v(t) - Delta(p)v with v is an element of L-p(0, T; W-0(1,p) (Omega)) boolean AND L ...

Effect of aerobic fitness on capillary blood volume and diffusing membrane capacity responses to exercise

open access: yesJournal of Physiology, 2016
Endurance trained athletes exhibit enhanced cardiovascular function compared to non‐athletes, although it is considered that exercise training does not enhance lung structure and function.

Relationship between diffusion capacity and small airway abnormality in COPDGene. [PDF]

open access: yes, 2019
Impaired single breath carbon monoxide diffusing capacity (DLCO) is associated with emphysema. Small airways disease (SAD) may be a precursor lesion to emphysema, but the relationship between SAD and DLCO is undescribed. We hypothesized that in mild COPD,
