The objective of this study is to compare the lower airways inflammatory response to infection/pulmonary exacerbation among children known to have Primary Ciliary Dyskinesia (PCD) with children known to have Cystic Fibrosis (CF) as measured by the presence of inflammatory mediators in expectorated/induced sputum.
The inflammatory response to infection and pulmonary exacerbation in CF is well documented, as is the response to intravenous antibiotic treatment. On the other hand, the inflammatory response to infection and treatment in PCD has not been well characterized. Given differences in disease progression, we hypothesize that children with CF respond to infection with a more exaggerated and prolonged inflammatory response than those with PCD.

Previous studies have demonstrated that exhaled nitric oxide can be useful to monitor the efficacy of anti-inflammatory treatment as well as to predict a risk of asthma relapse in asthmati...
The purpose of the study is to compare histone acetyltransferase (HAT) and histone deacetylase (HDAC) expressions and activities in induced sputum macrophages obtained from patients with m...
A minimum of 100 patients will be enrolled in the study to demonstrate which diagnostic treatment (oxygen or nitric oxide) is most capable of identifying patients with a reactive pulmonary...
The primary aim of this study is to exploit a difference between COPD patients, chronic smokers without COPD and healthy non-smoking subjects. This will help to assess the utility of infla...
This study is to evaluate the expression of biological markers in induced sputum and peripheral blood T lymphocytes of patients with combined pulmonary fibrosis and emphysema (CPFE). The f...
The goal was to determine if inhaled nitric oxide (iNO) for 3 weeks during neonatal care of high-risk preterm infants was associated with improved pulmonary function and exercise capacity or altere...
Rheumatoid arthritis (RA) is an autoimmune disorder characterized by bone and joint destruction, but other organ systems can also be involved. Recent studies have suggested that the disease may start ...
To examine the difference in the fractional exhaled nitric oxide (FeNO) between chronic obstructive pulmonary disease (COPD) patients with asthma-COPD overlap syndrome (ACOS) and patients with Non-ACO...
Nitric oxide is produced by enzymes called nitric oxide synthases. It fulfills many important functions in the human body, but produced in excess amount has a proinflammatory activity. Fractional exha...
To test the safety of a novel miniaturized device that produces nitric oxide (NO) from air by pulsed electrical discharge, and to demonstrate that the generated NO can be used to vasodilate the pulmon...
A CALCIUM-independent subtype of nitric oxide synthase that may play a role in immune function. It is an inducible enzyme whose expression is transcriptionally regulated by a variety of CYTOKINES.
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
An NADPH-dependent enzyme that catalyzes the conversion of L-ARGININE and OXYGEN to produce CITRULLINE and NITRIC OXIDE.
A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in ENDOTHELIAL CELLS.
A CALCIUM-dependent, constitutively-expressed form of nitric oxide synthase found primarily in NERVE TISSUE.
