Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mice's genes are so similar to humans', their findings could lead to the treatment of more genetic diseases.
Scientists at the University of California, Davis studied information from a data bank of mice's genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.
Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.
"This is extremely valuable for people with hereditary eye disease," said researcher Professor Ala Moshiri. "All researchers are going to start using these data. In the past, we knew the problem was there but we didn't know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable." Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby's parents!
Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice's genes to those of patients.
Questions you should ask yourself when you fail
The more new things we try the more failure we are likely to have.{#blank#}1{#/blank#}. Experiencing failure can be a learning experience and an opportunity for a fresh start. A good way to begin this process is by asking yourself some tough questions.
⑴What can I learn from this?
Take responsibility for what went wrong. OK, so it was not all your fault—but some of it was. Successful people don't make excuses or blame others. {#blank#}2{#/blank#} So you should look at the experience objectively(客观地).
⑵Do I need to acquire or improve some skills?
Did the problem reveal some lack of skill on your part? How could you learn or improve those skills? Perhaps there are books or courses or people you could turn to. {#blank#}3{#/blank#}
⑶Who can I learn from?
Is there someone to whom you can turn for advice? Did a boss, colleague or friend see what happened? {#blank#}4{#/blank#}. Most people do not ask for help because they believe it to be a sign of weakness rather than strength. It's not. It shows that you are ready to learn and change.
⑷What will I do next?
Now draw up an action plan. Will you try something similar or something different? Revisit your goals. Failure doesn't mean you have to give up; maybe you just need to change it in another way. {#blank#}5{#/blank#}
A. You can now reset your sights on your destination and plan a new course. B. Make them step stones to future success. C. They take responsibility for the failure. D. In fact the only way to avoid failure is to do nothing new. E. The important thing is how we deal with failure. F. Make a self-development plan to acquire the skills and experience you need. G. If they are constructive and supportive then ask them for some feedback (反馈) and guidance. |
