Targeting plasminogen activator inhibitor-1 in tetracycline-induced pleural injury in rabbits american journal of physiology lung cellular and molecular physiology (2017)
Elevated active plasminogen activator inhibitor-1 (PAI-1) has an adverse effect on the outcomes of intrapleural fibrinolytic therapy (IPFT) in tetracycline-induced pleural injury in rabbits. To enhance IPFT with prourokinase (scuPA), two mechanistically distinct approaches to ...
Time course of resolution of adhesions during fibrinolytic therapy in tetracycline-induced pleural injury in rabbits American Journal of Physiology - Lung Cellular and Molecular Physiology (2015)
The time required for the effective clearance of pleural adhesions/organization after intrapleural fibrinolytic therapy (IPFT) is unknown. Chest ultrasonography and computed tomography (CT) were used to assess the efficacy of IPFT in a rabbit model ...
Targeting of Plasminogen Activator Inhibitor 1 Improves Fibrinolytic Therapy for Tetracycline-Induced Pleural Injury in Rabbits American Journal of Respiratory Cell and Molecular Biology (2015)
Endogenous active plasminogen activator inhibitor 1 (PAI-1) was targeted in vivo with monoclonal antibodies (mAbs) that redirect its reaction with proteinases to the substrate branch. mAbs were used as an adjunct to prourokinase (single-chain [sc] urokinase [uPA]) ...
Mechanism of Fibroblasts Inflammatory Response to Pseudomonas aeruginosa Elastase Microbiology (2014)
Receptor tyrosine kinases, including the epidermal growth factor receptors (EGFR), are able to activate the mitogen-activated protein kinases (MAPK) via several adaptor proteins and protein kinases such as Raf. EGFR can be activated by a ...
Active α-macroglobulin is a reservoir for urokinase after fibrinolytic therapy in rabbits with tetracycline-induced pleural injury and in human pleural fluids American Journal of Physiology - Lung Cellular and Molecular Physiology (2013)
Intrapleural processing of prourokinase (scuPA) in tetracycline (TCN)-induced pleural injury in rabbits was evaluated to better understand the mechanisms governing successful scuPA-based intrapleural fibrinolytic therapy (IPFT), capable of clearing pleural adhesions in this model. Pleural ...
Intrapleural adenoviral delivery of human plasminogen activator inhibitor-1 exacerbates tetracycline-induced pleural injury in rabbits. American Journal of Respiratory Cell and Molecular Biology (2013)
Elevated concentrations of plasminogen activator inhibitor–1 (PAI-1) are associated with pleural injury, but its effects on pleural organization remain unclear. A method of adenovirus-mediated delivery of genes of interest (expressed under a cytomegalovirus promoter) to ...
Liposomal antibiotics for the treatment of infectious diseases Expert Opinion on Drug Delivery (2013)
Introduction: Liposomal delivery systems have been utilized in developing effective therapeutics against cancer and targeting microorganisms in and out of host cells and within biofilm community. The most attractive feature of liposome-based drugs are enhancing ...
Inhibition of PKC attenuates Pseudomonas aeruginosa elastase-induced epithelial barrier disruption American Journal of Respiratory Cell and Molecular Biology (2011)
Pseudomonas aeruginosa pulmonary infection compromises the human airway epithelium, and can be especially devastating to immunocompromised or debilitated individuals. We have reported earlier that P. aeruginosa elastase (PE) increases paracellular permeability in epithelial cell monolayers ...
Intrapleural low-molecular-weight urokinase or tissue plasminogen activator versus single-chain urokinase in tetracycline-induced pleural loculation in rabbits Experimental Lung Research (2009)
The authors compared the ability of a single dose of the proenzyme single-chain urokinase (scuPA), low-molecular-weight urokinase, tissue plasminogen activator (tPA), or a mutant site-inactive scuPA to resolve intrapleural loculations at 72 to 96 hours ...
Regulation of the Inflammatory Response in Health and Disease (2009)
The ability of multi-cellular organisms to mount a concerted response is an evolutionary advantage. In the case of bacterial challenges, the multicellular organism is tested by a diverse, complex and dynamic challenges, and must adapt ...
Activity and Interactions of Liposomal Antibiotics in Presence of Polyanions and Sputum of Patients with Cystic Fibrosis Biology Faculty Publications and Presentations (2009)
Background: To compare the effectiveness of liposomal tobramycin or polymyxin B against Pseudomonas aeruginosa in the Cystic Fibrosis (CF) sputum and its inhibition by common polyanionic components such as DNA, F-actin, lipopolysaccharides (LPS), and lipoteichoic ...
Bismuth–thiol incorporation enhances biological activities of liposomal tobramycin against bacterial biofilm and quorum sensing molecules production by Pseudomonas aeruginosa International Journal of Pharmaceutics (2009)
Recurrent pulmonary infection and inflammation are major risk factors for high morbidity and mortality in patients with cystic fibrosis (CF). As such, frequent antibiotic use and drug resistant bacterial strains are main concerns in individuals ...
Co-encapsulation of gallium with gentamicin in liposomes enhances antimicrobial activity of gentamicin against Pseudomonas aeruginosa Journal of Antimicrobial Chemotherapy (2008)
The aim of this study was to enhance the antimicrobial efficacy of a liposomal gentamicin formulation with gallium metal (Lipo-Ga-GEN) against clinical isolates of Pseudomonas aeruginosa. Sputum isolates of P. aeruginosa from cystic fibrosis patients were ...
Pseudomonas aeruginosa elastase induces IL-8 production in the lung cells via the epidermal growth factor/extracellular signal-regulated proteins/NFÎºB pathway Biology Faculty Publications and Presentations (2008)
Background: The induction of chemokine secretion by fibroblasts is crucial for the migration of leukocytes into the parenchyma of the injured lung. Several bacterial products activate the lung’s structural as well as immune cells to ...
Liposomal Bismuth-Ethanedithiol Formulation Enhances Antimicrobial Activity of Tobramycin International Journal of Pharmaceutis (2008)
Pseudomonas aeruginosa and Burkholderia cenocepacia (formally, genomovar III genotype of Burkholderia cepacia complex) have emerged as serious opportunistic resistant pathogens in patients with cystic fibrosis (CF). We have developed a liposomal formulation containing bismuth-ethanedithiol (BiEDT) and tobramycin to overcome bacterial ...
Pulmonary infection in Cystic Fibrosis: Role of quorum-sensing. Recent Development in Signal Transduction Research (2008)
Chronic lung infections are the major cause of morbidity and mortality in individuals suffering from Cystic Fibrosis. The chronic infections are caused by opportunistic pathogens residing in the CF lungs and are a major medical ...
Bactericidal efficacy of liposomal aminoglycosides against Burkholderia cenocepacia Journal of Antimicrobial Chemotherapy (2007)
