abstract::Endothelin-1 (ET-1) is a potent endogenous vasoconstrictor that was recently shown to exhibit bronchoconstrictive properties in vitro. In asthmatic patients, the expression of ET-1 peptide was also shown to be increased in endobronchial biopsies. Thus, we postulated that ET-1 could be higher in subjects with nocturnal...

abstract::Clinicians are frequently faced with patients in whom the radiographic resolution of community-acquired pneumonia seems delayed. Previous studies of radiographic resolution of the disease have yielded conflicting results. We prospectively assessed the radiographic resolution of pneumonia in 81 non-immuno-compromised p...

Other studies have pointed to a prominent role for chemoreceptor stimuli. We postulated that mechanoreceptor stimuli f...

abstract::The failure of patients to adhere to physician-prescribed regimens, either pharmacologic or behavioral, has been well documented in medical literature. Poor adherence to asthma medication regimens has been repeatedly demonstrated in both children and adults, with rates of nonadherence commonly reported from 30 to 70%....
