MI: Introduction, the function and implication of circadian rhythm, also, the author states the possible benefits of drugs related to this research can influence people's lives in the future.
1. The brief introduction of circadian rhythm, a biological clock functions to control human body temperature, blood pressure, hormone, etc.
2. SCN is an important area locates in the hypothalamus in our brain. The experiment shows that a rat which has been removed its SCN would not function well to control its daily and night activities.
3. Normally, the biological clock is activate 10-20mins longer than the daily hours of 24 hours. The reason is that human are competitive for food, goods and other stuffs in order to survive. And the biological clock is helping us to survive.
4. Also, the clock genes can stimulate the production of protein. Cyc and Per gene, then the author talks about how these two genes and other two genes interact each other. For example, people who sleep late and wake up late suffer from Per gene? ( 忘记了)
5. The biological cycle can influence people's lives by encountering the jet lag if people travel to different regions with different time. For people who live in the dark, their biological cycle can be changed as well. Because sometimes the biological cycle wouldn't stop to work even though the light is dim or in dark room. Thus, it's better to suggest people to sleep in a dark room without bright light, and wake up normally when the sunlight comes out, in this case, the biological cycle will start to function againSome people sleep early at 7pm and wakes up at 1am or 5am, while others sleep very late at night and couldn't wake up in the morning. The latter one actually encounters the syndrome of delayed sleep deprivation.
6. The scientists explore the deeper use of biological cycle to help in curing the cancer and tumor by reducing the number of tumor cells. The recent study also found that the aging problem can influence the biological cycle, an influence can cause the older rat's biological cycle functioning slower than that of the regular young rat.
