WASHINGTON, April 3 (Xinhua) -- Scientists have confirmed that metabolic syndrome, a constellation of conditions that increases the risk of heart disease and diabetes, may also increase the risk of the two most common types of liver cancer, according to data presented at the American Association for Cancer Research's 102nd Annual Meeting 2011, held in Orlando, Florida on April 2-6.Katherine McGlynn, a senior investigator at the National Cancer Institute, said approximately one-third of the U.S. population has metabolic syndrome, which is defined as the co-occurrence of at least three of the following five conditions: raised blood pressure, elevated waist circumference, low HDL or "good" cholesterol, raised triglyceride levels and raised fasting plasma glucose levels.According to McGlynn, persons with these conditions may be at increased risk of developing hepatocellular carcinoma and intrahepatic cholangiocarcinoma.For the current study, researchers identified 3,649 cases of hepatocellular carcinoma and 743 cases of intrahepatic cholangiocarcinoma. They compared the medical history of these patients with the medical histories of 195,953 cancer-free adults.Statistical analyses showed that the persons with liver cancer were significantly more likely than cancer-free persons to have a prior history of metabolic syndrome: 37.1 percent of patients with hepatocellular carcinoma had pre-existing metabolic syndrome, as did 29.7 percent of patients with intrahepatic carcinoma; only 17.1 percent of the cancer-free adults had metabolic syndrome.Liver cancer incidence has been rising since the 1980s in the United States. The factors related to the increase are not well understood. "A lot of attention has focused on viral risk factors, but a significant part of the increase may be due to metabolic syndrome, as well as to diabetes and obesity," said McGlynn."The prognosis for liver cancer is only marginally better than the prognosis for pancreatic cancer, with a five-year survival of approximately 10 percent," she said. "Prognosis is more favorable, however, when liver cancers are diagnosed at early stages when they are small and localized to the liver."

NAIROBI, Feb. 23 (Xinhua) -- The East Africa Community (EAC) and the Chinese government held talks on Wednesday to explore new areas of cooperation and boost trade between both sides.A statement from the EAC Secretariat said China's Ministry of Commerce Director Department of West Asian and African Affairs Chai Zhijing held discussions with Secretary General of the East African Community Juma Mwapachu on bilateral cooperation. "The Chinese delegation were at the EAC Headquarters to explore areas of cooperation specifically trade and investment opportunities in areas such as agriculture, animal-husbandry, production and processing of mineral and other natural resources, manufacturing, commerce and logistics, and tourism," the statement said.It noted that the delegation wants to know how China could support and facilitate cross-border infrastructure projects such as transport, communication and power.The Chinese and EAC officials also discussed cooperation in human resource development and training.Speaking during the meeting, Mwapachu said the visit by the director will open further the cooperation space between China and the EAC.He said the prevalence of Chinese firms in the region was very high in the construction industry and some other infrastructural developments.He noted that Chinese companies were involved in the construction of the EAC Arusha-Namanga-Athi River Road projectThe EAC secretary general said the regional economic bloc, which comprises Kenya, Uganda, Tanzania, Rwanda and Burundi, was truly looking forward to forging a lasting relationship with China.Chai said China has very good economic and cultural relations with all the five partner states of the East African Community and that all the five states were enjoying economic stability.He said EAC had a reputable framework for integration and development for the region, adding that "these form the solid basis for establishing cooperation with the People's Republic of China."The two sides agreed to come up with a concrete framework for engaging each other in the identified areas of cooperation, within one month.

WASHINGTON, April 4 (Xinhua) -- Scientists have identified a gene that appears to play a role in regulating how much alcohol people drink, in a study of over 47,000 people published Monday in the Proceedings of the National Academy of Sciences.The researchers say that finding a common genetic variation influencing levels of alcohol consumption may lead to a better understanding of mechanisms underlying alcohol drinking behavior in the general population.The gene, called "autism susceptibility candidate 2", or AUTS2, has previously been linked to autism and attention deficit hyperactivity disorder, but its function is not known.The new study, by an international consortium led by scientists at Imperial College London and King's College London, found that there are two versions of the AUTS2 gene, one three times more common than the other. People with the less common version drink on average five percent less alcohol than people with the more common version.The gene is most active in parts of the brain associated with neuropsychological reward mechanisms, suggesting that it might play a part in regulating the positive reinforcement that people feel when they drink alcohol.Alcohol consumption is known to be partly determined by genes but until now the only gene known to make a notable contribution was the gene encoding alcohol dehydrogenase, an enzyme that breaks down alcohol in the liver.Professor Paul Elliott, from the School of Public Health at Imperial College London, said: "Of course there are a lot of factors that affect how much alcohol a person drinks, but we know from twin studies that genes play an important role. The difference that this particular gene makes is only small, but by finding it we've opened up a new area of research into the biological mechanisms that control drinking."

CANBERRA, April 14 (Xinhua) -- The Australian federal government could struggle to get its carbon tax through parliament, as key independent Member of Parliament (MP) Tony Windsor on Thursday warned the plan may never become a reality.Windsor, who is one of the independents Prime Minister Julia Gillard will rely on to get her carbon tax pass the Parliament, said while climate action will benefit the bush, he will not "vote for something that does nothing"."There is no carbon tax, there may not be a carbon tax," he told ABC News on Thursday morning."The prime minister doesn't have the numbers, as I understand it at the moment."I have a vote, others do as well, so you can never guarantee something before it gets through a minority parliament."Windsor said people in his rural New South Wales electorate were concerned about the lack of detail around the proposed carbon tax.Gillard played down his comments, saying that Windsor, who sits on the multi-party climate change committee, had been "perfectly consistent" in his approach to the carbon price debate."He does believe climate change is real ... that pricing carbon is the best way, an important way, of tackling climate change," Gillard told ABC Radio on Thursday."(But) he's going to look at the (legislative) package and wait to the end and then judge (it)."Gillard added that the Labor government remains determined to introduce a carbon tax from mid-2012 followed by an emissions trading scheme.

MOSCOW, May 24 (Xinhua) -- Russia's Soyuz TMA-20 spacecraft with three crew members onboard has landed in Kazakhstan on Tuesday, said the Mission Control Center (MCC) outside Moscow.The spacecraft undocked from the International Space Station early Tuesday, carrying Russian cosmonaut Dmitry Kondratyev, European Space Agency (ESA) astronaut Paolo Nespoli and NASA astronaut Catherine Coleman back to Earth.According to the center, the Soyuz TMA-20 landed in the Kazakh steppe at 6:27 Moscow time (0227 GMT). Some 17 planes and helicopters and several rescue vehicles had conducted search works.Flight engineers Catherine "Cady" Coleman of the U.S. (L) and Italian Paolo Nespoli (R), and Russian cosmonaut and station commander Dmitry Kondratyev are seen after the Soyuz capsule landed, about 150 km (93 miles) southeast of the Kazakh town of Zhezkazgan May 24, 2011. A Russian Soyuz capsule delivered an international trio of astronauts back to Earth on Tuesday after six months on the International Space Station, parachuting through clear skies toward a safe landing on the Kazakh steppe.Deputy head of Federal Medical and Biological Agency Vyacheslav Rogozhkin said Italian astronaut Naspoli had some health problem after landing."Two crew members are fine, the third one has some problems with his vestibular system," Rogozhkin told a press conference after the landing.In December, the Soyuz TMA-20 was launched from the Kazakh Baikonur space center with three crew members.The next launch of manned spacecraft to the ISS was scheduled in early June.
