(redirected from dose-response curves) curve [kerv] a line that is not straight, or that describes part of a circle, especially a line representing varying values in a graph. dose-effect curve (dose-response curve) a graphic representation of the effect caused by an agent (such as a ...

In 9 asthmatic patients log(dose)-response curves were obtained on 4 successive days with the Wiesbadener Doppelinhalator (WDI) and the De Vilbiss (De V) 645 nebulizer, respectively. log(dose)-response was expressed as a quadratic regression equation. From those equations the dose, causing a...
FIGURE 2-1.Possible dose-response curves 1. Threshold.The existence of a threshold in health effects of pollutants has been debated for many years. A threshold dose is the lowest dose at which there is an observable effect. Curve A inFigure 2-1illustrates a threshold response: There is no...
IC50,EC50 EC20 Dose Response Curves Sigmoidal Fitting/Dose Response Curves Sigmoidal fitting, or dose-response fitting, is a type of analysis that is often used to analyze dose-response relationships, the competition of a ligand for receptor binding (competitive binding assays), or the voltage ...
The same term "dose-response curve" describes the relationship between the number of ingested microbes or their logarithm, and the probability of acute illness or death (type I), and between a disinfectant's dose and the targeted microbe's survival ratio (type II), akin to survival curves ...
The drug's potency and efficacy can be obtained from the dose response curves. Potency indicates the amount of drug needed to produce an observable effect. Limited clinical significance can be actually obtained from the potency. It is only useful for drug selection if the potency of a drug is...
1.Random error exists not only in toxicity experiments but also in the fitting of dose-response curves(DRC).毒性实验存在随机误差,同时剂量-效应曲线(DRC)拟合也会产生误差。 2)Dose-effect curves剂量效应曲线 3)Dose-effect curve剂量-效应曲线 1.Dose-effect curves established by radiation doses and ...
