[Q]: Question: Does identification of structural alert for liver and kidney toxicity using repeated dose toxicity data?
Answer: It was not possible to assign an unambiguous mode of action for all the SAs, but a mechanistic explanation is provided for some of them. Such achievements may help in the early identification of liver and renal toxicity of substances.
[A]: yes


[Q]: Question: Is variation in mortality among populations higher for pymetrozine than for imidacloprid and spiromesifen in Trialeurodes vaporariorum in greenhouses in Finland?
Answer: High variation in resistance levels to pymetrozine among populations within natural whitefly dispersal limits reflects variation in the usage of this compound among individual greenhouse crop producers. Thus, resistance management is recommended at the individual greenhouse crop producer level, even in a dense production cluster. © 2014 Society of Chemical Industry.
[A]: yes


[Q]: Question: Does mR imaging relaxometry allow noninvasive characterization of in vivo differentiation of muscle precursor cells?
Answer: MR imaging relaxation and diffusion measurements can be used as potential biomarkers for noninvasive in vivo monitoring of the myogenic differentiation process from muscle precursor cells to mature skeletal muscle tissue in muscle cell therapy.
[A]:
yes
