Quantum theory of dynamic multiple light scattering

open access: yes, 2007
We formulate a quantum theory of dynamic multiple light scattering in fluctuating disordered media and calculate the fluctuation and the autocorrelation function of photon number operator for light transmitted through a disordered slab.

Clinical and radiographic features of sarcoidosis in menopausal women: The impact on therapeutic approach and prognosis [PDF]

open access: yesVojnosanitetski Pregled, 2010
Background/Aim. Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. The aim of the study was to determine are there significant differences in clinical manifestations, radiographic and lung function findings and therapeutic approach

The 6 minute walk in idiopathic pulmonary fibrosis: longitudinal changes and minimum important difference [PDF]

open access: yes, 2010
The response characteristics of the 6 minute walk test (6MWT) in studies of idiopathic pulmonary fibrosis (IPF) are only poorly understood, and the change in walk distance that constitutes the minimum important difference (MID) over time is ...

Serum uric acid as a marker of microvascular damage in systemic sclerosis patients [PDF]

open access: yes, 2016
Background: Microvascular damage of skin and internal organs is a hallmark of systemic sclerosis (SSc). Serum uric acid (UA) represents a marker of inflammation and endothelial dysfunction.

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

open access: yesRespiratory 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.

Liquid heat capacity in the approach from the solid state: anharmonic theory

open access: yes, 2011
Calculating liquid energy and heat capacity in general form is an open problem in condensed matter physics. We develop a recent approach to liquids from the solid state by accounting for the contribution of anharmonicity and thermal expansion to liquid ...

Clinical and serological features of systemic sclerosis in a multicenter African American cohort: Analysis of the genome research in African American scleroderma patients clinical database. [PDF]

open access: yes, 2017
Racial differences exist in the severity of systemic sclerosis (SSc). To enhance our knowledge about SSc in African Americans, we established a comprehensive clinical database from the largest multicenter cohort of African American SSc patients assembled

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

open access: yesPLoS 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 ...

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,

Determining kinetic constants and transport efficiencies at membrane interfaces to optimize the removal/recovery of Cu(II) through lulk liquid membranes containing benzoylacetone as carrier [PDF]

open access: yes, 2017
The removal, separation, and enrichment of heavy metals in aqueous solutions has become a prime concern over the last few decades because of both their adverse effects on the ecosystem and living organisms and their valuable resource character.
