The concentration of Cu that kills 50% of larvae (LC50) and the concentration of Cu that causes 50% inhibition of normal larval development (EC50) were determined by probit analysis (piecewise linear regression analysis) using measured concentrations of dissolved Cu at the beginning of the experime...

increases the plasma concentration and decreases the brain concentration of nicotine. Interestingly, our work indicates that despite the sustained nicotine binding by the an- tibodies, active immunization may not necessarily alter the metabo- lism of nicotine to cotinine, suggesting that the vaccine ...
In contrast, the ECOD-activity remained inhibited in the prochloraz-exposed daphnids for 12h following transfer to azole-free medium, which correlated with elimination of the measured internal prochloraz concentration (DT95≈13h). These results indicate that lethal toxicity of the azole fungicides is...
The picture below shows you the aquatic environmental hazard classification criteria for asubstance. LowerLC50/EC50/NOECindicates higher toxicity. Please note thatdegradationandbio-concentrationshall also be taken into account. When classifying amixturecontaining multiple components, we will ne...
With PriSm 9, X0 is a parameter that must be set to a constant value, but you can set it to any value in the nonlinear regression parameters dialog. •New equations to fit the absolute EC50 (different than the usual relative EC50). Multiple t test analysis The multiple t test ...
The lowest concentration inducing alterations in cell viability (LOAEC) after 24 h exposure to MeHg was 3000 nM for neurospheres generated from hiPSC-derived hNPCs, and 1000 nM in neurospheres derived from primary hNPCs, while EC50 was similar in the two models [41]. In hiPSC-derived ...
Regarding in vitro studies, anti- inflammatory activity is exhibited by EC50 (µg/mL) (corresponding to the sample concen- tration that inhibits 50% of NO production) for various studied plants, meaning that a low EC50 concentration results in high anti-inflammatory activity. Concerning in vivo...

The non-Aroclor® PCBs (PCB11, 206, 207, 208, and 209) reach a concentration peak in Lake Ontario and in the Indiana Harbor Ship Canal in the fifties, and a second peak in the seventies. These PCBs are associated with the production of commercial paint pigments and dyes, which were ...
