Well, in Barnes and Noble reviews of Daniel's story, one might find various opinions. Some reviews could praise the plot for being engaging and full of twists. For example, if it's a mystery story about Daniel, the reviewers might talk about how they were kept on the edge of their seats trying to figure out what would happen next.
Mouse experimentBefore medical research results could be applied to humans, they often needed to go through layers of experiments, especially in live experiments. White mice were common subjects in live experiments.
There were many reasons why white mice became common experimental subjects. First, it had a strong reproductive ability. It only took 1 - 2 months from birth to reproductive ability, and the average pregnancy period was about 20 days. A female mouse could give birth to 4 - 7 litters a year, with a litter of 8 - 15 cubs. The experimental results could be seen earlier. Secondly, the genetic similarity between mice and humans was high, and the base pairs on the embryos were similar to those of humans. Thirdly, it was large in quantity and could meet the needs of a large number of experiments. Fourthly, it was small in size and easy to control, and the living environment was simple, easy to manage, and low in feeding costs. Fifth, they matured early and could breed all year round. On average, they could give birth to ten children at a time, which was convenient for genetic selection and reduced the cost of experiments. Sixth, it was relatively docile and would not take the initiative to attack people. Even if it was bitten, the wound was not big and was relatively easy to deal with. Seventh, after selection, the physiological differences between individuals were very small, and it was easy to eliminate interference options in the experiment. Eighth, their genes were similar to humans but they were not related to humans.
In terms of drug research and development, every newly developed drug that wanted to be listed in the market had to undergo complete experiments. Among them, live experiments were the highlight. There were two stages to live experiments. First, a long experiment had to be carried out on various animals. During the process, a lot of white mice would be consumed. Only after countless experiments on animals had been carried out to ensure safety could they apply for human experiments.
During the experiment, there would be some unexpected situations, such as the mouse running away while weighing. The experimenter needed to find it in time, because if it was not found after a long time (such as one night), the mouse might not be used for the experiment anymore.
