In short, naïve mice were put under general anesthesia and headplated.
When the two sets of mice were put together in the same cage, the obese mice became lean.
For the hot-plate test, mice were put onto the hot plate set at 50, 55, or 60 °C, and the latency to lick, flinch, or jump was measured once for each animal.
After the injection, the mice were put in a dark chamber for 4 h, and then tumor region were stripped from the mice.
In the third set of experiments, the mice were put down at 6 and 24 h for the control, "5 %," "20%%," and "100%%," ligated groups.
But differences did crop up once the grownup mice were put through a series of standard behavioral tests.
When humanized mice and wild mice were put in mazes that engaged both types of learning, the humanized mice mastered the route to the reward faster than their wild counterparts, report Schreiweis, Graybiel, and their colleagues online today in the Proceedings of the National Academy of Sciences.
The mice were put in a chamber where they experienced foot shocks, causing them to freeze in fear.
As related on the Israeli news site Arutz Sheva, the mice were put to the test during a December 2009 controlled experiment in which explosive charges were planted on twenty-two people scattered throughout a Tel Aviv mall.
And when the two groups of mice were put on a high-fat diet at age 6 months, the trajectories of their weight and their metabolic health diverged even more dramatically.
To ensure constant body temperature during testing, mice were put on a warming source.
