A New Drug for Losing Weight

Scientists have developed a slimming drug that successfully suppresses appetite and results in a dramatic loss of weight without any apparent ill effects. The drug interferes with appetite control and prevents the build-up of fatty tissue. More importantly， the drug appears to prevent a serious decline metabolic rate——causing tiredness and lethargy——which is typically associated with living on a starvation diet. S a result， mice taking the drug lost 45 percent more weight than mice fed the same amount of food， which compensate for the lack of food by becoming more sluggish.

The scientists， from the Johns Hopkins University in Baltimore， said that C75 is likely to produce a similar effect on humans because appetite control in the brain is thought to be based largely on the same chemical pathways as those in mice. "We are not claiming to have found the fabled weight-loss drug. What we have found， using C75， is a major path way in the brain that the body uses naturally in regulating appetite at least in mice，" said Francis Kuhajda， a pathologist and senior team member. "We badly need effective drugs for weight loss. Obesity is a huge problem.

We"re hoping to explore the possibilities of this new pathway，" he said.

Discovering a biochemical. Pathway in the brain that controls appetite raises new prospects for eloping slimming aids. Research on leptin， a hormone produced in fatty tissue for controlling fat deposits， has so far failed to produce the expected slimming drug break-through. The latest study， published in the journal Science， showed that even moderate doses of C75 produced a significant loss of appetite， which returned to normal after a few months.

The scientists believe that C75， which they produced synthetically in the laboratory， binds to an enzyme called fatty acid sythase， which is involved in storing excess food intake as fat.

Inhibiting enzyme causes a build-up of a chemical in the liver which acts as a precursor to fat deposition. This precursor is thought to have an indirect effect on the brain， causing appetite suppression.

Normally， when animals fast， a hormone called neuropeptide Y increases sharply in the appe-tite control centers of the brain， stimulating the desire for food. However， when animals are given C75， levels of this hormone fall， leading to a loss of interest in food. Dr Kuhajda said discovering that C75 has no effect on metabolic rate is one of the most significant findings of the study. "If you try to lose weight by starving， your metabolism slows down after a few days，" he said. "It"s a survival mechanism that sabotages many diets. We see this in fasting mice. Yet metabolic rate in the C75-treated mice doesn"t slow at all. "Further animals studies will be needed before C75 could be tested on humans.

Living on a starvation diet may result in __________. 查看材料

A.a dramatic loss of weight without any ill effects

C.a slowdown of fat deposition

D.fatigue and inactivity

In the case of taste he may, musically speaking, have been more perceptive than he realised. A paper in Neurology by Giovanni Frisoni and his colleagues at the National Centre for Research and Care of Alzheimers's Disease in Italy, shows that frontotemporal dementia can affect musical desires in ways that suggest a regression,if not to infancy,then at least to a patient's teens.

Frontotemporal dementia, a disease usually found with old people, is caused, as its name suggests,by damage to the front and sides of the brain. These regions are concerned with speech, and with such" higher" functions as abstract thinking and judgment.

Two of such patients intrigued Dr Frisoni. One was a 68-year-old lawyer, the other a 73-year-old housewife. Both had undamaged memories, but displayed the sorts of defect associated with frontotemporal dementia—a diagnosis that was confirmed by brain scanning.

About two years after he was first diagnosed, the lawyer, once a classical music lover who re？ferred to pop music as" mere noise" , started listening to the Italian pop band "883". As his com？mand of language and his emotional attachments to friends and family deteriorated, he continued to listen to the band at full volume for many hours a day. The housewife had not even had the lawyer's love of classical music, having never enjoyed music of any sort in the past. But about a year after her diagnosis she became very interested in the songs that her 11-year-old granddaughter was listen？ing to.

This kind of change in musical taste was not seen in any of the Alzheimer's patients, and thus appears to be specific to those with frontotemporal dementia. And other studies have remarked on how frontotemporal-dementia patients sometimes gain new talents. Five sufferers who developed ar？tistic abilities are known. And in another case, one woman with the disease suddenly started com？posing and singing country and western songs.

Dr Frisoni speculates that the illness is causing people to develop a new attitude towards novel experiences, Previous studies of novelty-seeking behaviour suggest that it is managed by the brain's right frontal lobe. A predominance of the right over the left frontal lobe, caused by damage to the latter, might thus lead to a quest for new experience. Alternatively, the damage may have affected some specific nervous system that is needed to appreciate certain kinds of music. Whether that is a gain or a loss is a different matter. As Dr Frisoni puts it in his article, there is no accounting for taste.

The writer quotes Shakespeare mainly to

A．praise the keen perception of the great English writer.

B．support Dr. Frisoni's theory about a disease.

C．start the discussion on a brain disease.

D．show the long history of the disease.

China promises Internet bounty

Yahoo! will pay $ 1 billion for a stake in the Chinese e-commerce firm Alibaba. com as it battles other U.S. Internet companies for a foothold in China's fast-growing Internet market.

Other major U.S. Web players such as eBay, Amazon. com, Barry Diller's Interactive Corp. and Monster. com are shelling out big bucks for Chinese companies, although Yahoo! hit a new record.

Why the spending spree？

The same mason U. S. companies from Coca-Cola to General Motors have long beaten a path to China's door: The nation has a lot of people. And now it has a burgeoning middle class, primed to revel in prosperity by buying consumer goods.

Less than 8 percent of China's 1.3 billion people are online—but that still gives it 103 million Inter- net users, second only to the United States, with 203 million. By 2009, the number of Chinese Netizens is expected to surpass the number of Americans online. That year, Chinese e-commerce will be a $ 390.9 billion market, according to the research firm IDC.

Those colossal projections have U. S. investors salivating—even though actual Internet sales in China to date are minuscule. Yahoo's billion-dollar deal Thursday gives it a 40 percent stake in a company with just $ 68 million in 2004 revenue. It follows last week's debut of Baidu. com— "the Google of China"— which skyrocketed 354 percent on its opening day of trading on the Nasdaq stock market, despite having just $ 13.4 million in 2004 revenues. Google has a 2.6 percent stake in Baidu and reportedly would like more.

Moreover, e-commerce has some big obstacles in a country where credit cards are still, rare. Internet transactions are sometimes paid for by sending bicycle messengers with cash. PCs are beyond the reach of most of the multitudes, who had a gross national per capita income in 2002 of just $ 940, according to the World Bank.

But its massive demographics and surging economy—China's CDP grew 9 percent in 2004—make the People's Republic seem all the riper to U.S. companies. Now that explosive growth has slowed in the United States, Internet moguls see China as vast virgin territory.

"We are doubling down in China because the potential for Internet commerce in that country is simply extraordinary," eBay CEO Meg Whitman told analysts in February.

Internet firms in China "are getting in at the very beginning of a consumer economy that's really nascent," said Laura Martin, senior analyst with Soleil/Media Metrics in Pasadena, Calif. "First movers have the best advantage at creating enormous amounts of value."

Add to that the Chinese propensity for homegrown enterprises, and you've got a mini-gold rush as U. S, Internet firms vie for Chinese partners to help them penetrate beyond the Great Wall.

Peter Sealey, an adjunct professor of marketing at the University of California-Berkeley's Haas School of Business, was chief marketing officer for the Coca-Cola Corp. in 1979 when it entered China.

Like the U.S. Internet firms, Coke allied with Chinese companies. "You always want a partner on the ground who's native to the territory, who knows the political system, who has connections," Sealey said.

The soft-drink firm faced some marketing challenges. "Coke is an acquired taste," he said. "We had Fanta Orange soda—a taste (the Chinese) were accustomed to. We used to take a case of 24 bottles of Fanta and swap in two bottles of Coke. Then we had to run ads explaining that Coke should be consumed cold."

Internet firms are likely to face a different set of cultural barriers. The reliance on a cash economy is a big one. To help spur Web transactions, eBay is introducing its online payment system PayPal in China this year. Alibaba, Yahoo's new partner, already has a payment system called Alipay.
