However, the dose-response curve may not extend between the controls (the NS controls are considerably lower than the Bottom plateau) as seen below. So, how do we calculate the IC50? The relative IC50 is estimated by considering the Bottom and Top plateaus obtained by implementing the 4PL mo...
ECOSAR is a free tool, easy to install and use. It can be downloadedhere. After you have downloaded it and installed it, you will see the following main screen. To start using ECOSAR, you only need to input very limited substance info and then click "calculate" button. User Inputs for...
Dominance of cyanobacteria in phytoplankton communities creates undesirable situations in fresh, brackish, and salty waters worldwide. Dense cyanobacterial blooms may lead to serious health consequences for cattle, wildlife, pets, and humans (Carmichael1992; Paerl et al.2001; Huisman et al.2006). Such...
To calculate ternary complex model constants, the same data set was fitted to the allosteric EC50 shift model built into the Prism software (Equations 3 and 4) (24). Noncompetitive antagonism is described by the ternary complex model, in which the KD for a ternary complex equals KD/α for...
Processor has set of registers. Since processors are single-threaded, this set of registers belongs to just a single thread. For example, when you calculate a sum of two numbers: //-- assume we have two ints: a and bintc=a+b; ...
