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."

BEIJING, Feb. 1 (Xinhua) -- A plane carrying Chinese nationals who were stranded in Egypt arrived at Beijing Capital International Airport Tuesday afternoon.The plane, operated by the Air China International Corporation, arrived in Beijing at 16:50 p.m. Bejing time. The second plane, operated by Hainan Airlines, will arrive in south China's Guangzhou city later Tuesday.The two planes carry a total of 480 Chinese nationals."China has attached great importance to safety of the stranded Chinese nationals since demonstrations and protests broke out in Egypt on Jan. 28," said Chinese Foreign Ministry spokesman Hong Lei at a regular news briefing.Hong said China has taken a package of emergency measures including warning against travel and an around-the-clock hotline to provide consular protection and assistance for the Chinese nationals.The spokesman said that a working taskforce, composed of officials from China's Foreign Ministry, National Tourism Administration, Ministry of Public Security and Civil Aviation Administration, are currently working with the Chinese embassy in Cairo to provide assistance to stranded Chinese in Egypt and to try to facilitate their early return to China.

BEIJING, Jan. 30 (Xinhua) -- As of Jan. 28, 77.4 million mu (5.16 million acres) of crops had been harmed by the ongoing drought, and 2.57 million people were faced with drinking water shortages in China, the national drought control authorities said Sunday.Local governments of the affected regions must make efforts to monitor drought conditions, speed up the building of water projects, increase drought-fighting material reserves and grant subsidies to the drought-stricken population, said officials at a meeting attended by Chen Lei, deputy head of the Office of State Flood Control and Drought Relief Headquarters (SFDH).The National Meteorological Center (NMC) forecast the drought to worsen in the next two months, saying Sunday that the drought-hit north China and regions along the Yellow and Huaihe rivers would receive little rain or snow in February and March.Chen, also minister of water resources, stressed the importance of drought relief efforts, guaranteeing agricultural production and ensuring drinking water safety for boosting consumers' confidence, controlling consumer prices and inflation and maintaining economic growth.Since last Autumn when the drought began, local authorities have assigned 9.55 million people and 2.15 million sets of drought-fighting machineries to draw 8.2 billion cubic meters of water to irrigate 110 million mu of crop land.

BEIJING, March 15 (Xinhuanet) -- The number of Alzheimer patients is growing rapidly, so is that of unpaid caregivers, says a report released Tuesday by the Alzheimer's Association.Nearly 15 million caregivers, most of them family members but also friends, are providing billions of hours of unpaid care for Alzheimer's patients and other forms of dementia in the U.S. — 37 percent more than last year, the report says.Alzheimer's is the sixth leading cause of death in the nation, and the only one among the top 10 that have no prevention or cure, says William Thies, chief medical and scientific officer of the Alzheimer's Association.However, if people were more aware of early symptoms and were diagnosed sooner, then planning could help ease stress on patients and caregivers, according to Beth Kallmyer, senior director of constituent services of Alzheimer's Association."The toll on families is devastating," says Kallmyer, "Stress is extremely high, and one-third are experiencing depression."The time and stress of caring for an Alzheimer’s patient takes a physical toll, translating into nearly 8 billion dollars worth of extra health care costs for caregivers, the report says.

JERUSALEM, March 31 (Xinhua) -- Two researchers at the Hebrew University (HU) of Jerusalem have been honored with a prestigious award for their study of the connection between several inflammatory diseases, cancer and bacteria.Medical faculty members, Dr. Eli Pilarsky and Prof. Sigal Ben- Yehuda, won this year's Sir Zelman Cowen Universities Fund prize that recognizes significant achievement in the field of medicine.The prize committee noted the impressive contributions of Pilarsky and Ben-Yehuda in understanding complex diseases like cancer and antibiotic-resistant infections, and, in a first, decided to award the two scientists this year.Pilarsky told Xinhua that his research deals with the connection between chronic inflammatory diseases like hepatitis, and the development of cancer cells."The relevance of this discovery is that we were able to establish the link between the molecules secreted with such inflammations and the proliferation of cancer cells," Pilarsky explained, noting that "we discovered that the inflammation favors the cancer cells' growth, and now we are trying to find a way to manipulate these molecules to stop the cancer cells from appearing. ""The importance of these findings lies in the fact that 20 percent of the world's cancer cases are attributed to inflammation processes," Pilarsky pointed out.
