COPD represents one of the leading causes of mortality in the general population. This study aimed at evaluating the relationship between airway hyperresponsiveness (AHR) and COPD and its relevance for clinical practice. We performed a MEDLINE search that yielded a total of 1919 articles. Eligible studies were defined as articles that addressed specific aspects of AHR in COPD, such as prevalenc...

Activation of poly(ADP-ribose) polymerases (PARPs) is considered a key event in the molecular and cellular processes leading from acute asthma attacks to bronchial hyper-reactivity, leucocyte recruitment, chronic inflammation, airway remodelling and lung damage. The present investigation has been carried out to investigate the action of hydroxyl-dimethylaminomethyl-thieno[2,3-c]isoquinolin-5(4H...

BACKGROUND Adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) are thought to contribute to the airway inflammation and airway hyper-responsiveness (AHR) of allergic asthma. Some differences from allergic asthma have been noted, including airway neutrophilia, and the involvement of ICAM-1 in toluene diisocyanate (TDI) asthma is currently unclear. OBJECTIVE We utilized mice l...

BACKGROUND AND AIM Inflammatory cells involved in the pathophysiology of asthma express nicotinic receptor. Therefore 1,1 dimethyl(-4-)phenylpiperazinium (DMPP) in two doses were compared to dexamethasone in asthmatic guinea pigs. MATERIALS AND METHODS Six groups were included; Normal control and five asthmatic (OVA-sensitized and challenged) groups; which were treated for 10 days as follows:...

Animal models with a high predictive value for human trials are needed to develop novel human-specific therapeutics for respiratory diseases. The aim of the present study was to examine lung-function parameters in marmoset monkeys (Callithrix jacchus) that can be used to detect pharmacologically or provocation-induced AHR (airway hyper-responsiveness). Therefore a custom-made lung-function devi...

Asthma symptoms include wheezing, coughing, dyspnea, and chest tightness, as well variable degrees of airway blockage hyper-responsiveness. Many biomarkers have been widely studied in asthmatic children for asthma diagnosis monitoring. Clinical decisions related to control status traditionally based on subjective symptoms, rescue medication use, lung function changes. Biomarkers reflecting rema...

Asthma is a common chronic pulmonary inflammatory disease, featured with mucus hyper-secretion in the airway. Recent studies found that glucagon like peptide-1 (GLP-1) analogs, including liraglutide and exenatide, possessed a potent anti-inflammatory property through a protein kinase A (PKA)-dependent signaling pathway. Therefore, the aim of current study was to investigate the value of GLP-1 a...
