RATIONALE Nuclear factor (NF)-kappaB is a transcription factor known to regulate the expression of many inflammatory genes, including cytokines, chemokines, and adhesion molecules. NF-kappaB is held inactive in the cytoplasm, bound to I-kappaB. The removal of I-kappaB, via the actions of inhibitor of kappaB (I-kappaB) kinase-2 (IKK-2), allows NF-kappaB to(More)
BACKGROUND In allergic asthma, exposure to relevant antigens leads to an early asthmatic response (EAR) followed, in certain subjects, by a late asthmatic response (LAR). Although many subjects with asthma consider LAR to be one of the defining symptoms of their disease, and despite its widespread use in the clinical assessment of new therapeutic entities,(More)
BACKGROUND Continuous Performance Test (CPT) is a commonly used paradigm to assess attention disorders that could involve working memory processes. METHODS Event-related potentials (ERPs) during a CPT (X-AX) test were obtained in 16 healthy male students, with ages ranging from 9 to 11 years (X = 10.3). In grouped averaged ERPs, an endogenous slow(More)
Sixteen ADHD children and a control group were asked to reproduce the varying time duration of successively presented visual stimuli. Time estimation was poorer in ADHD children, who showed more impulsive errors. ERPs exhibited similar grand-mean waveforms for both groups during the estimating period, but they were significantly different during the(More)
Abediterol is a novel potent, long-acting inhaled β(2)-adrenoceptor agonist in development for the treatment of asthma and chronic obstructive pulmonary disease. Abediterol shows subnanomolar affinity for the human β(2)-adrenoceptor and a functional selectivity over β(1)-adrenoceptors higher than that of formoterol and indacaterol in both a cellular model(More)
The ovalbumin (OVA) model of allergic inflammation, both in rat and mouse is characterised by a late bronch-oconstrictive response (LAR) after allergen challenge that can be measured using whole-body plethysmogra-phy (WBP) in conscious unrestrained animals. Circadian oscillations of lung mechanical properties have been reported in conscious undisturbed(More)
The key factors governing the absorption of drugs from the lungs are deposition pattern, dissolution rate, solubility and permeability. Whereas the thin epithelium in the respiratory airways is generally considered to constitute a minor barrier in the overall absorption process, the other two components depend, among other parameters, on the formulation and(More)
Background RNA viruses are major causes of respiratory infections and known to exacerbate asthma and other respiratory diseases. The objective of the study was to use poly I:C, a synthetic analogue dsRNA, to elicit exacerbation in a model of allergic inflammation driven by house dust mite (HDM) in Freund's Complete Adjuvant (FCA). This model is(More)
