WASHINGTON, Dec. 5 (Xinhua) -- A recent study found that low vitamin D levels are significantly more prevalent in obese children and are associated with risk factors for type 2 diabetes. This study was accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism.High rates of vitamin D deficiency have been found in obese populations and past studies have linked low vitamin D levels to cardiovascular disease and type 2 diabetes. But the mechanisms by which obesity and its comorbidities are related to vitamin D deficiency are not fully known.This new study examined associations between vitamin D levels and dietary habits in obese children, and tested whether there were correlations between vitamin D levels and markers of abnormal glucose metabolism and blood pressure.In this study, researchers measured vitamin D levels, blood sugar levels, serum insulin, body mass index (BMI) and blood pressure in 411 obese subjects and 87 control non-overweight subjects. Study participants were also asked to provide dietary information including daily intake of soda, juice and milk, average daily fruit and vegetable intake, and whether or not they routinely skipped breakfast. BMI is a measurement of body fat calculated from weight and height."Our study found that obese children with lower vitamin D levels had higher degrees of insulin resistance," said Micah Olson, of The University of Texas Southwestern Medical Center in Dallas and lead author of the study. "Although our study cannot prove causation, it does suggest that low vitamin D levels may play a role in the development of type 2 diabetes.""Poor dietary habits such as skipping breakfast and increased soda and juice intake were associated with the lower vitamin D levels seen in obese children," said Olson. "Future studies are needed to determine the clinical significance of lower vitamin D levels in obese children ... and whether treatment with vitamin D can improve primary clinical endpoints such as insulin resistance.

BEIJING, Dec. 28 (Xinhuanet) -- A vagrant boy sat all huddled up in a corner of Beijing Railway Station, trying to keep himself warm in the chilly wind on Tuesday afternoon.He could only remember that he was 16 and that his home was far away from Beijing but failed to provide other vital information such as his name or home address.Two officials from the social assistance center for the homeless in Beijing's Dongcheng district came to his assistance within half an hour of receiving a passer-by's call. The boy was taken to the center's office for some paper work and then sent to a shelter for the homeless in Fengtai district.A teenager, unsure of his identity and living on a street corner near Beijing Railway Station, is helped by China Daily photographer Wang Jing on Tuesday before being taken to a care center."Our center handles about three or four similar cases every month. Those whose family cannot be contacted immediately are sent to the shelter," said Cao Hui, an official who came to the railway station to pick up the boy.The method of collecting vagrants and sending them to shelters would include an extra step by 2013, according to a notice jointly issued by eight government departments, including the Ministry of Civil Affairs (MCA), on Monday.The circular required the public security, urban management authorities and rescue centers nationwide to collect blood samples from vagrant children. Their DNA information will be recorded and checked against the national DNA database to see if these could be matched with that of missing children's parents', in case they were kidnapped or stolen by criminals.The eight government departments will start a year-long national campaign in 2012, aiming to return street children to their homes, which will be led by the MCA.The MCA urged provincial governments to set up special offices to coordinate the campaign.Civil Affairs minister Li Liguo said on Monday that the ministry will speed up revising the management regulations related to the homeless and beggars in cities, introduced in 2003. Detailed rules about how different government departments should cooperate with each other to help vagrant children would be formulated in the revised regulation.The notice also urged the civil affairs authorities to organize social workers to provide one-on-one psychological counseling and aid services to street children.Educational authorities in locations where the vagrant children are originally from are required to facilitate their returning to schools or vocational institutions. Those from poor families can have their school fees reduced or waived.Yu Jianrong, a professor with the Chinese Academy of Social Sciences and an initiator of a grassroots campaign to help child beggars, begun in January, applauded the government's consistent efforts to help street children to resume a normal life."The notice definitely shows the government's determination to keep children away from begging or performing on the street.""However, seeing no vagrant children on the street doesn't mean all problems have been solved. The government should make more efforts to improve the social security network for children," he added.Ablikim has been working with a non-governmental organization in Urumqi of Northwest China's Xinjiang Uygur autonomous region that has helped about 300 children - originally from Xinjiang who turned up on the streets of more prosperous cities, begging and picking pockets - to reunite with their families or put them in child rescue centers.The 27-year-old Uygur volunteer, urged the police to carefully check the identities of adults who brought several children to the railway station or bus stops, as they could well be human traffickers.

JERUSALEM, Dec. 11 (Xinhua) -- Kfir Damari, a communication systems engineer, has a dream: to land a miniature spacecraft on the moon sometime in 2013.Damari is one of the founders of Team SpaceIL, a non-profit organization representing Israel in the Google Lunar X Competition. The prize: 20 million U.S. dollars to the first of the 26 international teams currently registered that lands an unmanned craft on the moon, moves it a minimum of 500 meters across the lunar surface and transmits live high-resolution images back to earth."It's a tough mission, but I believe that if everyone in Israel joins hands it's possible," Damari told Xinhua.It is exactly the kind of entrepreneurial spirit that Israel, a country largely void of natural resources, counts on to make it a global leader in technological innovation.The two other men behind the initiative are Yonatan Winetraub, 25, a systems engineer at Israel Aerospace Industries (IAI) and a graduate of NASA's International Space University, and Yariv Bash, 31, a computer scientist and electronics engineer. The three first met at an innovation conference held by IAI a year ago.They describe the lander as a nano-satellite, whose design was revealed at the project's official inauguration ceremony on Thursday. The vessel weighs 100 kg, 80 percent of which are fuel, and is outfitted with rocket boosters and a panoramic camera."It's somewhat of a cellular phone sitting on a large fuel tank. All the technology that we require is basically contained in a typical smartphone with its communication and imaging features," Damari said.Launched in 2007, the Lunar X Prize aims to encourage space enthusiasts and engineers worldwide to develop cheap technologies for robotic space exploration.The Israelis have slated a modest 15 million U.S. dollars for the endeavor, 90 percent of which must come from private contributions according to the competition's rules. They have already raised 3.5 million dollars.The fact that they have formed a non-profit NGO in itself is worthy of praise. Most other teams have obtained the patronage of private corporations for whom money is not a problem, with some reportedly allotting up to 100 million U.S. dollars.To compensate for the disparities in funding, Damari and his partners have enlisted the support of 120 local volunteers, many of them engineers holding top positions in the technological and scientific community as well as the country's leading defense industries.Rona Ramon, the widow of Israeli astronaut Ilan Ramon killed aboard the Columbia Space Shuttle in 2003, was one of the sponsors too.In a bid to keep costs down, SpaceIL is heavily relying on the existing knowledge accumulated by Israel's defense industries over the past decades in building and launching mainly small, lightweight communications and military surveillance satellites into space.The challenge, Damari said, is to take that know-how a step further. The professionals who have volunteered for the project, among them some of Israel's most revered space experts, are currently grappling with several issues, including the ignition system, optic-visual navigation, beaming imagery to earth and the intricacies of enabling the nano-satellite a smooth lunar landing.SpaceIL is still searching for a third party that they will lease to launch their vehicle into space. Once there, they will have to navigate it to the moon on their own.While 20 million U.S. dollars is a major motivator for anyone, the Israelis said they're not seeking personal gain, but rather plan to invest the prize money in the vision that originally prompted their registration in December last year: inspiring the country's younger generation to pursue engineering and the sciences and to dream big, just like Neil Armstrong did when he disembarked from the Apollo 11 and took the first step on the moon in 1969.The funds, they said, will be funneled to educational programs that seek to rejuvenate youths' interest in science disciplines, which have been on the decline in the country's high schools in recent decades."We hope to attract the next generation of kids, to enable them to be engineers and scientists and to make sure that we have more people that can build spaceships in Israel in the future," said Damari.He and the other men behind the initiative also acknowledge that their motives are no less driven by patriotism. Winning the Lunar X has the potential to create national pride and put Israel "on the map as a start-up nation" by accomplishing a feat reserved for superpowers."The moon is something you see every day. I think that for me personally, space exploration is the way to enlist the nation to do something that has not yet been done," said Damari, who started programming aged six and wrote his first computer virus aged 11."It's also about exploring new borders, going the distance. (The project) will leverage Israel's space industry. I'm sure that all the industries that will partner with us will learn a lot and develop new applications, especially for the civilian market," he said.On Thursday, Israeli President Shimon Peres, whose name has become synonymous with the nation's hi-tech industries, honored the trio by unveiling their model at the ceremony held at MABAT -- IAI's missiles and space division near Tel Aviv."More than Israel is leading technology, it is likely to lead Israel. It's the key to our economy ... If they win the prize, and I'm sure they will, it will also reward Israel with the deepest appreciation and the best deterrence," Peres told a crowd of senior executives from local defense industries."I admire your audacity and vision," he complimented the three scientists.Will they realize their ambition? Damari expressed humble optimism, "It's not easy, but certainly possible ... We believe we can win."

SANTO DOMINGO, Sept. 30 (Xinhua) -- Haitian health authorities on Friday said the number of deaths caused by cholera increased to 6,435 in the Caribbean country since October 2010.The Haitian Health Ministry said the number of people infected with cholera almost reached half a million, although the ministry repeated the epidemic was decreasing.The report said 455,727 people had been treated due to cholera, and 242,205 had to be hospitalized.The western province of Artibonite suffered the plague most with 1,196 deaths. The southwest province of Nippes registered the smallest death toll of 181.Meanwhile, in the Haitian capital Port-au-Prince, 221 people have been killed since October 2010 when the epidemic first broke out in central Haiti.The epidemic is supposedly due to the spill of dregs from a Nepalese camp, which is part of the UN Stabilization Mission in Haiti (MINUSTAH).The Dominican Republic, a country neighboring the island country Haiti to the east, has also been suffering the disease since November 2010, which has killed at least 135 people there.

SHIJIAZHUANG, Dec. 3 (Xinhua) -- More than 3.48 million people in rural areas of north China's Hebei Province have been given access to safe drinking water this year, a local official said Saturday.Authorities in the province have invested more than 1.7 billion yuan (270 million U.S. dollars) so far in 2011 in building drinking water infrastructure, said Liang Jianyi, deputy director of the Hebei Provincial Department of Water and Resources.More than 32 million rural people in Hebei, especially in mountainous and coastal areas, had long suffered from unsafe water, with problems including high fluorine and alkaline contents, Liang said.From 2005 to 2010, the provincial authorities put almost 6 billion yuan into providing safe drinking water for 13 million rural residents, he added.
