Thanks...


which 3) is kind of funny.
why should it be present tense?
which is kind of funny.
this "which" is refered to a matter of past.

zhenzhen，每次都是画龙点睛阿，太佩服了， afoot, halving,少了您怎么都是不完整啊。。。

Great answer!

Learning to find stuff on the internet is a vital skill for everyone and you can't find a better tool than Google. So learn to google!

When you are talking about a fact now, you use the present tense even if the fact was established in the past. For example: The fact that he did not have anything to eat all day causes him to feel dizzy now.

August 20, 2007: 60-Second Science Virus Infection Could Be Contributing to Obesity

The presence of human adenovirus-36 seems to transform adult stem cells found in fatty tissue into fat cells--infection with the virus may therefore be a factor in at least some cases of obesity. Steve Mirsky reports.

On July 26th, we’ve reported that obesity could be sort of contagious when you friends gain weight, you feel more **carrying if you extra pounds. Now comes report that common virus may contribute to obesity epidemic. Researchers found that adenovirus-36 can transform adult stem cells obtained from fatty tissue into fat cells, then announced the finding in the meeting of the American Chemical Society. Adenovirus-36 infection is known to cause some resportorian? issues. Other researchers reviewed that animals infected with the virus accumulated fat. And another study showed that 30% of obesity people had the infection, compared with the only 11% of lean individuals. What the new study did was provide direct evidence to that virus actually cause fat levers to increase. The researchers collected fat from suction(liposuction) patients and icy ** adult stem cells. They exposed half to the virus and found that the infected stem cells turned into fat cells. So, vaccine or antiviral drugsmay yet get drafted for the battle of the boggy.

On July 26, we've reported that obesity could be sort of contagious when your friends gain weight, you feel more (conf) carrying if you're extra pounds. Now comes to report that common virus may contribute to obesity epidemic. Researchers found that human adenovirus 36 could transform adult stem cells obtained from fatty tissue into fat cells .They announced the finding at the meeting of American chemical society. Adenovirus 36 infection is known to cause some worse peto issues. Other researchers reviewed that animal's infected with virus accumulated fat. And other study showed that 36percent of obesity people had infection compare with those only 11percent of lean individuals. What a new study did was provided direct evidence to that virus actually causes fat level to increase. The researcher's collected fat from lab sucking patience that isolated adult stem cells. They exposed half to the virus and found the infection stem cells trading to fat cells .So the vaccines of antivirus drugs may yet get drafted for the battle of botch.  


绿色高亮的是不确定的，谢谢指正。

some different from kelediguo :

Other researchers reviewed(revealed) that animals infected with the virus accumulated fat.

这是应该是researchers 而不是research, 因为这里的Other 相对的是前面的they (announced the finding),面这个they指的是researchers of this study.

~~~~~~~~~~~~~~~~

Top down tips:
1.get drafted --drafted 原意指征兵之意,这里用了这一层意思..
2.respiratory的发音是[risˈpaiərətri],但不知为什么steve没有发ai这个长元音
3.lean 有a.瘦的；贫乏的之意
4.adenovirus [微生]腺病毒
5.fatty tissue脂肪组织
stem cells干细胞
liposuction〈医〉皮下脂肪切除术

get drafted for the battle of the bulge.
是什么意思啊？谢谢！

我觉得这个地方是 researchers 而不是research,因为这里的Other针对 的是前面的they(They announced the finding in the meeting of the American Chemical Society.)这个they是指这个study的研究者.

还有1个发音问题
respiratory的发音是[risˈpaiərətri],但不知为什么steve没有发ai这个长元音

reference material:

Common virus may contribute to obesity in some people, new study shows
BOSTON, Aug. 20, 2007 ?Scientists today reported new evidence that infection with a common virus may be a contributing factor to the obesity epidemic sweeping through the United States and other countries. In laboratory experiments they showed that infection with human adenovirus-36 (Ad-36), long recognized as a cause of respiratory and eye infections in humans, transforms adult stem cells obtained from fat tissue into fat cells. Stem cells not exposed to the virus, in contrast, were unchanged.

In addition, the study reported identification of a specific gene in the virus that appears to be involved in this obesity-promoting effect. The findings, which could lead to a vaccine or antiviral medication to help fight viral obesity in the future, were presented at the 234th national meeting of the American Chemical Society.

not saying that a virus is the only cause of obesity, but this study provides stronger evidence that some obesity cases may involve viral infections,says study presenter Magdalena Pasarica, M.D., Ph.D., of the Pennington Biomedical Research Center, a campus of the Louisiana State University system.

all infected people will develop obesity,she notes. would ultimately like to identify the underlying factors that predispose some obese people to develop this virus and eventually find a way to treat it.

Pasarica was part of the original research group which demonstrated that the Ad-36 virus was capable of causing animals infected with the virus to accumulate fat. Led by Nikhil Dhurandhar, Ph.D., now an associate professor at Pennington Biomedical Research Center, the group also conducted a noted epidemiologic study the first to associate a virus with human obesity showing 30 percent of obese people were infected with the Ad-36 virus in comparison to 11 percent of lean individuals. But evidence that the virus could actually cause fat levels to increase in human cells was lacking until now, Pasarica says.

In the current study, Pasarica and her associates obtained adult stem cells from fatty tissue from a broad cross-section of patients who had undergone liposuction. Half of the stem cells were exposed to Ad-36 and the other half were not exposed to the virus.

After about a week of growth in tissue culture, most of the virus-infected adult stem cells developed into fat cells, whereas the non-infected stem cells did not, the researchers say.

Funded by the National Institutes of Health (NIH), Dr. Dhurandhar抯 group recently identified a gene in the Ad-36 virus that appears to be involved in causing fat accumulation observed in infected animals. That gene, called E4Orfl, is now emerging as a promising target for future human therapies, such as vaccines and anti-viral medicines, aimed at preventing or inhibiting the obesity virus, she says.

The exact mechanism by which the virus might cause obesity in people is currently unknown, says Pasarica, who does not rule out the possibility that other human viruses may also contribute to obesity. Researchers also do not know how long the virus remains in the body of obese individuals nor how long its fat-enhancing effect lasts once the virus is gone. However, Pasarica notes a recent study demonstrated that animals that developed the virus remained obese up to six months after their infection was gone. More studies are needed, especially in humans, she adds.

Pasarica and her associates are now in the process of trying to identify the factors that predispose some people with the virus to develop obesity while others do not, but results of this investigation are not yet available, they say.

About 97 million adults in the United States are overweight or obese, according to NIH, and face an increased risk of Type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, and other health disorders. Obesity has many established causes that include over-eating, eating high-fat foods, lack of exercise, a genetic predisposition and certain medications.
