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.

HANOI, Oct. 25 (Xinhua) -- The hand-foot-mouth disease (HFMD) and dengue were on the rise across Vietnam, reported the Vietnam Preventive Medicine Administration (PMA) on Tuesday.As of Oct. 23, the country had more than 76,120 HFMD patients and 135 fatalities. The number of incidents has increased significantly over the last few weeks, with an average of 2,000-2, 500 new cases reported each week.Southern Ho Chi Minh City and Binh Duong, Long An and Quang Ngai were the most-hit localities, said the report.Meanwhile, dengue was also reported on the rise. In the first ten months of the year, there were more than 41,200 infected cases and 32 fatalities. Currently, an average of 2-3 cases a day were hospitalized by dengue infections, mainly from capital Hanoi.Epidemiologists said that the increase of HFMD and dengue was due to the lack of specialized medicine and preventive vaccines. In addition, complicated climate change, environment pollution and low awareness of the disease among the community have contributed to the spread of the diseases nationwide.

BEIJING, Dec. 26 (Xinhua) -- The Standing Committee of the National People's Congress (NPC), China's top legislature, began here Monday to deliberate draft interpretations on two annexes of the Basic Law of the Macao concerning election issues.Li Fei, deputy director of the Commission of Legislative Affairs of the NPC Standing Committee, explained the draft interpretations to lawmakers.The Basic Law of the Macao Special Administrative Region (Macao SAR) was adopted in 1993 and went into effect on Dec. 20, 1999.Annex I to the Basic Law provides a method for selecting the SAR's chief executives while Annex II sets the method for the formation of its legislative assembly.Clause 7 of Annex I of the Basic Law says that if there is a need to amend the method for selecting the Chief Executives for 2009, and the terms subsequent to the year 2009, such amendments must be made with endorsement of a two-thirds majority of all the members of the Legislative Council and the consent of the Chief Executive, and they shall be reported to the Standing Committee of the National People's Congress for approval.Clause 3 of Annex II says that if there is a need to amend the method of forming the Legislative Assembly of the Macao Special Administrative Region in and after 2009, such amendments must be made with the endorsement of a two-thirds majority of all the members of the Assembly and the consent of the Chief Executive, and they shall be reported to the Standing Committee of the National People's Congress for the record.Li said that the phase "if there is a need to amend ..." should mean that they may or may not be amended.The decision-making on whether such necessity exists is reserved to the central authorities, or the NPC standing committee, said Li, adding that the Macao SAR government, rather than members of the Legislative Assembly, individually or jointly, should be the proper entity to propose any such amendments.Li also explained that if no amendment to the methods is adopted, the two Annexes should still apply.The full text of draft has not been made public yet, but the points raised by Li are identical to those in the committee's prior interpretations on Hong Kong SAR's Basic Law in 2004.During the deliberation, members of the committee noted that draft would help to safeguard Macao's long-term prosperity and stability.They also believed that it was "proper and necessary" to adopt the draft during this week's session as Macao's chief executive Fernando Chui Sai On had made the issue of modifying the method a "major work" in his policy address for the fiscal year 2012.Chui's statement recognized that "there is agreement that it is appropriate to properly modify the two methods in order to adapt to society's development and progress" and promised to "submit a proposal on whether to modify and - if so - how to modify the methods."Macao expects the formation of its fifth Legislative Assembly in 2013, and the selection of its fourth Chief Executive in 2014.

BEIJING, Oct. 18 (Xinhuanet) -- Some seaweeds can kill the reef-building corals around them by emitting anti-coral chemicals, a new study found.The study was published Monday in the online edition of the journal Proceedings of the U.S. National Academy of Sciences (PNAS).The researchers investigated the interactions between eight different species of seaweed and three species of coral growing in the waters nearby the Fiji Islands, and identified a class of anti-coral organic compounds known as terpenes.These chemicals, found on the surfaces of several species of seaweed, can kill the coral by suppressing its photosynthesis.The finding suggests that the living space competition with seaweeds could be a factor of the coral's worldwide decline.Plant-eating fish normally controls seaweed growth on coral reefs, but the populations of these consumers are declining by the overfishing, which eventually resulted in the seaweed's dominant position, according to the researchers.Despite overfishing, pollution and warming oceans are also the contributors to coral's worldwide decline, said Jennifer Smith, a marine ecologist at the University of California, San Diego.

WASHINGTON, Nov. 21 (Xinhua) -- The use of acupuncture for children is common and acupuncture is generally safe for children when performed by "appropriately trained practitioners," Canadian researchers reported Monday in online journal Pediatrics.Researchers at the University of Alberta looked at data from 37 studies of needle acupuncture, spanning 60 years, on children from birth to age 17, and assessed the association between needle acupuncture and various levels of adverse events in children. They found that of 279 adverse events identified, 253 were mild, one was moderate and 25 were serious.Serious side effects included bleeding, infections, and heart and lung problems. One child may have contracted HIV. But the researchers said the serious side effects were related to substandard conditions from the care provider, rather than acupuncture's technique itself. They concluded that in trained hands, pediatric acupuncture is safe.Acupuncture has been around for thousands of years, and traditional Chinese theory suggests needle placement helps balance the body's energy flow, called "qi". Acupuncture is sometimes used to treat headaches, migraines, back and joint pains, cramps, and chemotherapy-induced nausea. Estimates show 150,000 U.S. children undergo acupuncture each year.
