According to the BBC, the British Association for the Blind said that smokers are twice as likely to be blind as non-smokers. Cigarette smoke contains toxic chemicals, which can irritate and hurt eyes. For example, heavy metals such as lead and copper will gather in the lens, leading to lens opacity, that is, cataract. Smoking can also damage retinal blood vessels and aggravate vision problems related to diabetes. The probability of smokers suffering from age-related macular degeneration increased by 3 times, and the probability of sudden blindness caused by optic neuropathy increased by 16 times.
Blocking specific protein can kill tumor cells.
Research at the University of Pennsylvania has found that tumor cells can be killed by blocking some protein. For many years, researchers have tried to target a gene called MYC, but it has been difficult to achieve it. When MYC gene is mutated or overexpressed, it will drive the growth of many cancer types. Researchers at the University of Pennsylvania's perelman School of Medicine found that protein, named ATF4, is the companion of the MYC gene. When this protein is blocked, cancer cells will produce too much protein and die. These findings may point to a new way to treat cancer. Researchers are also trying to confirm whether this method will lead to serious off-target effect.
● Exciting music makes sports easier.
Researchers from Okana Root, School of Health and Sports Science, University of British Columbia, found that listening to inspiring music during exercise won't make you feel so tired, even for people who don't usually exercise much. The researchers asked the subjects to do 1 minute high-intensity interval training in three different environments, including listening to inspiring music, playing other music and no music. The results show that listening to inspiring music can make participants enjoy the sports pleasure brought by high-intensity interval training more than playing other music or not playing music.
Researchers say that stimulating music can keep the exerciser's attention away from the adverse reactions produced by the body, such as rapid heartbeat or muscle aches, thus reducing the difficulty of exercise.
● Excessive muscle growth or eating disorders.
In addition, this disorder is also related to social disorder and depression. Among the 1489 1 to 18 years old 1 respondents, about 22% of men and 5% of women showed this eating disorder. These people eat a lot of abnormal diets or take dietary supplements and anabolic steroids in order to gain muscles. Researchers say that dietary supplements are a regulatory blind spot, which may cause liver and kidney damage in extreme cases, while anabolic steroids and other hormones will cause health problems in the short and long term.
