Cancer is a Genetic Disease
The role of somatic mutations in cancer was debated for many years. Witkowski (1990) puts that historical debate in context with a comprehensive time line of developments in cancer research interleaved with developments in basic genetics and molecular biology.
Boveri (1914, 1929) often gets credit for the first comprehensive theory of somatic genetic changes in cancer progression (Wunderlich 2002). Tyzzer (1916) used the term “somatic mutation” to describe events in cancer progression. In the 1950s, Armitage and Doll (1954, 1957) cautiously described the stages of multistage progression as possibly resulting from somatic mutations but perhaps arising from other causes. Burdette (1955), in a comprehensive review of the role of genetic mutations in carcinogenesis, tended to oppose the central role of mutations in progression. In (1969), Fould’s extensive summary of cancer progression also downplayed the role of mutation.
Reducing your sleep
As you recall, during jet lag we travel over several time zones. If we travel 2 time zones to the West, our body temperature rhythm will still be set to 2 hours ahead. In response we feel out of place and it takes a while for our body temperature rhythm to adjust to the new time zone.
In the same way, when we try to reduce the amount of time we spend sleeping, it takes a while for our bodies to adjust to the new sleeping time. The main challenge with reducing sleeping is understanding how sleep works, which we have over-come by going through all this information together. The second challenge is people tend to misread their bodies. If you feel tired and drowsy during the day ask yourself this question: “Am I tired right now because I need sleep? Or is it because of the way I’m living my life or acting at the current moment?” Even if you take a highly energetic person and place them in front of a TV for 2 hours, they WILL GET TIRED! This is why it’s important to realize that increasing your daily energy levels is as important as decreasing your sleep, they work together. This post gives you introductory information about how to reduce your sleep.
How to sleep?
In order to reduce the total amount of time you spend sleeping, you must increase the quality of your sleep first. Both light exposure and your activity levels affect your body temperature rhythm in a very big way. high intensity light has a huge effect on the strength of your sleeping system.
If you expose yourself to light during the day, your body temperature rhythm will “peak” at a higher point and will fall at a later point. You’ll experience better sleep and will be able to lower your amount of sleep. If you get inadequate light exposure your body temperature will be closer to “flat-lining”, preventing quality sleep and lowering your energy levels throughout the day. Lack of sunlight also inhibits melatonin hormone secretion, this further promotes lower energy levels and sleep difficulties.
Michael C. Hall – Dexter Morgan – Cancer
Michael C. Hall is 38 years old. He’s at the top of his profession. His role as Dexter Morgan has brought him acclaim, awards and fame. Dexter Morgan maybe a killer by night but in real life he is currently battling cancer. Michael C. Hall, 38, has been diagnosed with Hodgkin’s lymphoma, a type of blood cancer.
