WASHINGTON, Oct. 4 (Xinhua) -- Green tea may slow down weight gain and serve as another tool in the fight against obesity, according to U.S. Pennsylvania State University food scientists.Obese mice that were fed a compound found in green tea along with a high-fat diet gained weight significantly more slowly than a control group of mice that did not receive the green tea supplement, said Joshua Lambert, assistant professor of food science in agricultural sciences."In this experiment, we see the rate of body weight gain slows down," said Lambert.The researchers, who released their findings on Tuesday in the online version of Obesity, fed two groups of mice a high-fat diet. Mice that were fed Epigallocatechin-3-gallate -- EGCG -- a compound found in most green teas, along with a high-fat diet, gained weight 45 percent more slowly than the control group of mice eating the same diet without EGCG.In addition to lower weight gain, the mice fed the green tea supplement showed a nearly 30 percent increase in fecal lipids, suggesting that the EGCG was limiting fat absorption, according to Lambert. The green tea did not appear to suppress appetite. Both groups of mice were fed the same amount of high-fat food and could eat at any time."There seems to be two prongs to this," said Lambert. "First, EGCG reduces the ability to absorb fat and, second, it enhances the ability to use fat."A person would need to drink ten cups of green tea each day to match the amount of EGCG used in the study, according to Lambert. However, he said that recent studies indicate that just drinking a few cups of green tea may help control weight."Human data -- and there's not a lot at this point -- shows that tea drinkers who only consume one or more cups a day will see effects on body weight compared to nonconsumers," said Lambert.

WASHINGTON, Nov. 18 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy to E. coli derived asparaginase and pegapargase chemotherapy drugs used to treat ALL.Acute lymphoblastic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes, a type of white blood cell. White blood cells help the body fight infection and are formed in the bone marrow.Erwinaze is injected directly into the muscle three times a week and works by breaking down one of the body's protein building blocks (the amino acid, asparagine) that is present in the blood, and is necessary for the growth of all cells. Leukemia cells cannot produce this protein building block. When a patient is treated with Erwinaze the leukemia cells die. Normal human cells are able to make enough asparagine for their own needs through biosynthesis and will not be affected by treatment with Erwinaze."The approval of Erwinaze underscores the FDA's commitment to the approval of drugs for conditions with limited patient populations with unmet medical needs using novel trial endpoints," said Richard Pazdur, director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research.Side effects associated with Erwinaze treatment include serious allergic reactions, inflammation of the pancreas, high blood levels of liver enzymes, blood clotting, bleeding, nausea, vomiting and high blood sugar.

BEIJING, Jan. 23 (Xinhua) -- An online survey has revealed that Chinese people have a mixed opinion on Sunday's Spring Festival TV gala, the 30th of its kind since 1983, albeit many of them agree that there were innovations and improvements in it.As of 10:00 p.m. Monday, about 48 percent of some 71,000 respondents in the poll held by sina.com.cn, one of China's major portal websites, said they think the gala fall short of their expectations.Another 23 percent of them said they think the gala was just fine, and only 10 percent said it was splendid.The gala, an annual grand celebration broadcast by the China Central Television on the eve of the traditional Spring Festival, China's lunar New Year, is the most-watched TV event in the country."I can see the efforts of the gala staff, but it is still not good enough," said netizen "roam the life" at the Sina weibo, a popular Twitter-like microblogging website.At the Sina weibo website, the topic "grumble at the 2012 Spring Festival TV gala" has outnumbered others with over 64 million comments and become the hottest topic of Monday.Nonetheless, many people acknowledge the innovations and improvements in the gala.The gala made some attempts to take a more public-friendly approach by inviting some "grassroots" performers, such as farmer-singer Zhu Zhiwen, as well as cutting all commercials during the broadcast.A dance performance depicting a romance of peacocks and starring Yang Liping, a well-known dancer in China, is the most-followed topic at the gala's official weibo account, drawing over 3,500 comments.The audience was also impressed by a piano duet played by Li Yundi, first prize winner of the the 14th Frederic Chopin international piano competition, and Leehom Wang, a Chinese-American pop singer-songwriter.Moreover, about 59 percent of the online poll respondents said the stage design was quite cool."There are really many improvements in the gala, but it is absolutely difficult to please everyone," wrote weibo user "Wawamiaowaiwai."Unlike their elder generation, the young generation in China has more diversified options for entertainment, and it is of great challenge to attract them at the Spring Festival celebration, said Xia Xueluan, a professor of sociology with Peking University.

SAN FRANCISCO, Oct. 5 (Xinhua) -- Microsoft announced Wednesday that it will bring cable television content to its Xbox video game console over the upcoming holiday season, expanding the console into an entertainment hub.According to the company's press release, nearly 40 world- leading TV and entertainment providers such as HBO GO and BBC will stream their content through the Xbox Live service in more than 20 countries and regions.Users will be able to sift through shows online with the Kinect motion sensor device for Xbox 360 and Bing voice search, Microsoft said.To watch TV programs via Xbox as an alternate delivery system, customers have to already subscribe to the TV services and Microsoft's Xbox Live Gold service of 60 U.S. dollars per year."Today's announcement is a major step toward realizing our vision to bring you all the entertainment you want, shared with the people you care about, made easy," Microsoft said in the press release.Microsoft first entered the gaming console market in 2001 with the Xbox, the predecessor to the Xbox 360.

PARIS, Dec. 23 (Xinhua) -- French health authorities on Friday urged 30,000 women to remove the local-made breast implant, pledging that relevant expenses would be covered by the state.The health ministry said in a statement that they spot "no increased risk of cancer currently in women wearing the PIP (Poly Implant Prothese) brand compared with other implants.""However, well-established risks associated with these prostheses are rupture and irritant gel may lead to inflammatory reactions, making it difficult to explant," the statement added.French Health Minister Xavier Bertrand advised French women who have the PIP implants to get them taken out "as a preventive measure but not of an urgent nature." The removal of the implant will be at the state's expense.The recommendation came after eight cases, mainly breast cancer, were reported recently among women with PIP implants.The involved implant was produced by the French company PIP, once the world's third-largest producer of silicone implants who sold its products to tens of thousands of women in more than 65 countries, mainly in South America and western Europe.
