To be considered a valid test of reactivity, at least one heart rate and one behavioural measurement in the test had to change significantly between treatments (tranquilizer administation versus sham tranquilizer administration), and behavioural measures had to be displayed in at least 75% of the trials.
In the runway test, no significant difference in heart rate values in tranquilized and non-tranquilized horses was found, and no behavioural attribute was displayed in more than 52% of the trials; therefore it was rejected as a valid test of reactivity.
Experimental test of reactivity of pulverized coal milled in a new rotating impact disintegrator developed at the IT SB RAS (Novosibirsk, Russia) showed that the coal activation threshold was reduced by a factor of two or more, making it easier to ignite and burn more efficiently.
Our results do not corroborate the strain differences in reactivity found in the other two tests of emotional reactivity.
Rearing in each of the three tests of emotional reactivity was correlated with several measures in the learning and memory tasks.
We assessed whether behavior in different tests of emotional reactivity is correlated with performance in aversively motivated learning tasks, using four strains of rats generally considered to have a different emotional reactivity.
Lastly, we evaluated whether performance on the different tests of emotional reactivity was correlated with performance on aversively motivated learning tasks, to determine whether cognition is affected by emotional processes.
Rearing in the three tests of emotional reactivity was negatively correlated with the mean distance swum in the sMWM task: rats that were more active in these tests swam a shorter distance in the sMWM to escape onto the submerged platform.
Then, we performed transposon mutagenesis and obtained ca. 16,500 kanamycin resistant mutants from which we selected 23 that displayed a stable R phenotype both in vitro and in mice, as judged by the crystal violet test, lack of reactivity with anti O-PS antibodies and phage typing.
For example, using the approach for at least two of the signs apprehension or nervousness, over-reactivity (as evaluated by tests of over-reactivity including repeated spontaneous startle responses) and ataxia or hypermetria, not all experimentally inoculated, BSE-confirmed cattle were clinical suspects under these criteria.
For example, recognition of the significance of certain clinical tests resulted in their subsequent application during the study (e.g. tests of over-reactivity).
