Blood Test Forecasts Concussion Severity
Levels of a protein fragment in the blood paralleled how long head injuries benched hockey players.  
December 15, 2014 |By Ingrid Wickelgren

Confusion is one symptom of a concussion. But confusion may also characterize decisions about how soon to let an athlete play after taking a hit to the head. Sizing up symptoms such as dizziness and nausea is subjective, after all. Now a study suggests that a blood test could objectively determine whether or not the damage is bad enough to put a player on the bench. The work is in the Journal of Neurotrauma.

A strong blow to the head causes chemical changes within nerve cells that damage their structural proteins. Among the debris is a protein fragment called SNTF—which in more severe cases, spills into the bloodstream.

The new study followed 20 professional hockey players who got concussions with symptoms that lasted six days or more. And blood levels of SNTF were much higher one hour to six days later than were levels of the protein fragment in eight other athletes who had gotten concussions that cleared up within five days. Levels were also low in 45 non-concussed players tested during the pre-season.

A blood test for SNTF might thus forecast recovery time from a head injury. Combined with other neurological tests, levels of this molecule could help doctors tell athletes when it’s safe to suit up again.

As a graduate in Aganda,Moses find that his hometown is lack of electricity and citizens have to go a long way to find
wood .So he quits job and trys to find an alternitive fuel.Finally,he introduces a technology that can turn plant waste
to fuel.

1. 1'15 A study suggests that a blood test for SNCF can forcast recovery time from a head injury. The people who got severe hit have high blood levels of SNTF than other less severe wounded and non-concussion people.

2. 1'39 A visit of home made him quit his job and learn everything he could about renewable resource. The success of his invention makes the farm waste become charcoal, protecting the trees in Uganda and giving the opportunities to poorest people.

3.2'34 Conditions before Mose invented the new technology are compared with the conditions after the invention. This part also describe some things that M did to help the people in Uganda and the achievement of those helps.

4.2'20 A satellite was launched to observe the magnitude....(not understand)

5.The images help the scientists observe the magnitude field clearly.

6.Triclosan is antibiotic-resistant microbe, which can result in many bad results. Many countries have banned the use of triclosan.

1:38 One person work out the method of turning waste to fuel to make the children in his hometown have the opportunity to go to school.
2:48 This invention help large number of families to make more money and live a better live. Many people join in this career and spread it to other countries.
2:20 Milky way to find the magnetic field.
1:51 The milky way may help people find the clue about the origin of universe magnetic.
3:08 A kind of chemical thing can go in to people's body through the environment. The effect isn't known. Governments make laws to prevent adding this thing into food.
9:46 A river is grabbed by other investors and the local people are suffered from lack of water. There are examples that environment is destroyed by this action. People should be careful.

Blood test can forecast the concussion,some way can help doctor to deal with it.

Time 2
2'16'20 Moses realized that many children had to move the wood in a long distance so that it would influence thier time to study.Thus,he resigned and found that they could turned waste into fuel.Then it makes their poor people's life better.

Time 3
3'32'28 Before Moses made the eco-fuel Africa,people came across many difficulties in life. When Moses creates eco-fuel to Uganda,it benefits a lot to local people's life.And Moses also plants more trees and schools.

Time 4
2'50'29 Magnetic fields in the Milky Way is like a picture.

Time 5
2'27'25 The Milky Way's overall magnetic field is not about the cosmology but it is a key clue about the first place in the universe.

Time 6
3'08'42 Microbes exploits their killer. Finally,M was banned in the products.

Obstacle
9'26'70 The government sells the water and lands for foreign argibusiness without local people's agreements,they don't even know it.And some experts said that the environment will be worse with the foreign agribusiness.
