Syndecan-2 is a novel target of insulin-like growth factor binding protein-3 and is over-expressed in fibrosis [PDF]

open access: yes, 2012
Extracellular matrix deposition and tissue scarring characterize the process of fibrosis. Transforming growth factor beta (TGFβ) and Insulin-like growth factor binding protein-3 (IGFBP-3) have been implicated in the pathogenesis of fibrosis in various ...

Numerical Simulation of Particle Motions in Cascade Impactor and Human Respiratory System [PDF]

open access: yesMATEC Web of Conferences, 2021
Dry powder inhalations (DPIs) have gathered attention as a treatment for respiratory diseases due to the large effective absorption area in a human lung. A cascade impactor is generally used to investigate the inhalation performance of DPIs.

Spatial and temporal changes in extracellular elastin and laminin distribution during lung alveolar development [PDF]

open access: yes, 2018
Lung alveolarization requires precise coordination of cell growth with extracellular matrix (ECM) synthesis and deposition. The role of extracellular matrices in alveogenesis is not fully understood, because prior knowledge is largely extrapolated from ...

Amelioration of bleomycin-induced lung fibrosis in hamsters by dietary supplementation with taurine and niacin: biochemical mechanisms. [PDF]

open access: yes, 1994
Interstitial pulmonary fibrosis induced by intratracheal instillation of bleomycin (BL) involves an excess production of reactive oxygen species, unavailability of adequate levels of NAD and ATP to repair the injured pulmonary epithelium, and an ...

Not All Antibodies Are Created Equal: Factors That Influence Antibody Mediated Rejection. [PDF]

open access: yes, 2017
Consistent with Dr. Paul Terasaki's "humoral theory of rejection" numerous studies have shown that HLA antibodies can cause acute and chronic antibody mediated rejection (AMR) and decreased graft survival. New evidence also supports a role for antibodies

Non-linear relationship of cell hit and transformation probabilities in a low dose of inhaled radon progenies [PDF]

open access: yes, 2009
Cellular hit probabilities of alpha particles emitted by inhaled radon progenies in sensitive bronchial epithelial cell nuclei were simulated at low exposure levels to obtain useful data for the rejection or support of the linear-non-threshold (LNT ...

Genetic partitioning of interleukin-6 signalling in mice dissociates Stat3 from Smad3-mediated lung fibrosis [PDF]

open access: yes, 2012
Idiopathic pulmonary fibrosis (IPF) is a fatal disease that is unresponsive to current therapies and characterized by excessive collagen deposition and subsequent fibrosis.

A Compartment-Based Mathematical Model for Studying Convective Aerosol Transport in Newborns Receiving Nebulized Drugs during Noninvasive Respiratory Support

open access: yesPharmaceutics, 2020
Nebulization could be a valuable solution to administer drugs to neonates receiving noninvasive respiratory support. Small and irregular tidal volumes and air leaks at the patient interface, which are specific characteristics of this patient population ...

Inhalable spray-dried chondroitin sulphate microparticles: effect of different solvents on particle properties and drug activity [PDF]

open access: yes, 2020
Spray-drying stands as one of the most used techniques to produce inhalable microparticles, but several parameters from both the process and the used materials affect the properties of the resulting microparticles.

Influence of excipients on spray-dried powders for inhalation [PDF]

open access: yes, 2014
Two areas attracting considerable attention when developing effective pulmonary drug delivery systems include the improvement of aerosolisation efficiency of the inhaled formulation and the controlled release of drug from the formulation following ...
