Effects of long-acting and short-acting beta-agonists on methacholine dose-response curves in asthmatics.
Regular use of short-acting beta-agonists may decrease control of asthma and increase airway responsiveness to bronchoconstrictor stimuli. The aim of this study was to determine the effects of regular treatment with the long-acting beta-agonist, salmeterol, on the methacholine dose-response curve (DRC) in mild-to-moderate asthmatics. Changes in methacholine airway responsiveness were measured i...
متن کاملImplicit dose-response curves.
We develop tools from computational algebraic geometry for the study of steady state features of autonomous polynomial dynamical systems via elimination of variables. In particular, we obtain nontrivial bounds for the steady state concentration of a given species in biochemical reaction networks with mass-action kinetics. This species is understood as the output of the network and we thus bound...

هدف از انجام این تحقیق مشخص کردن موثرترین متد اصلاح خطا بر روی دقت آهنگ و تاکید تلفظ کلمه در زبان انگلیسی بود. این تحقیق با پیاده کردن چهار متد ارائه اصلاح خطا در چهار گروه، سه گروه آزمایشی و یک گروه تحت کنترل، انجام شد که گروه های فوق الذکر شامل دانشجویان سطح بالای متوسط کتاب اول passages بودند. گروه اول شامل 15، دوم 14، سوم 15 و آخرین 16 دانشجو بودند. دوره مربوطه به مدت 10 هفته ادامه یافت و د...
15 صفحه اولThe steep dose-response curves of anesthesia.
To the Editor:—The critique by Eger et al. on the article by Eckenhoff and Johansson concerns combining the dose–response curves of several ion channels to make them steeper. The slopes of the in vivo studies are steep, whereas those of the in vitro studies are gradual. Both groups anticipate that when several binding sites among ion channels are combined, the dose–response curves may become st...
متن کاملEffects of fluticasone propionate on methacholine dose-response curves in nonsmoking atopic asthmatics.
Methacholine is frequently used to determine bronchial hyperresponsiveness (BHR) and to generate dose-response curves. These curves are characterized by a threshold (provocative concentration of methacholine producing a 20% fall in forced expiratory volume in one second (PC20) = sensitivity), slope (reactivity) and maximal response (plateau). We investigated the efficacy of 12 weeks of treatmen...
