CAPE TOWN, Dec. 15 (Xinhua) -- More people voluntarily get HIV tests in the Western Cape province, an indication of people's rising awareness of the epidemic, authorities said on Thursday.Nearly 11,000 people in the province have been tested over the past 10 days as authorities stepped efforts to halve the number of HIV transmissions over the next few years, according to official figures.Authorities expect more people to be tested when the monthly campaign ends by the end of December.In December last year, 67,111 people were tested.This year's figure is expected to be higher than that of last year, said Western Cape Premier Helen Zille.The campaign, known as Know Your Status and Win, may become a regular feature in the province, said Zille.To encourage more people to take part in the campaign, the province offers awards to several winners by drawing, ranging from 10,000 rand (about 1,250 U. S. dollars) to 50,000 rand (about 6, 250 dollars)."The bottom line is that people respond to incentives," said Zille, who hailed the campaign a success.She said the reality was that those who stubbornly did not want to get tested, were those crucially in need of doing so.While the data still had to be audited, preliminary results indicated a spike in the number of people who were tested.There was also a significant increase at routine testing center that were not part of the campaign, said Zille. Of 22.9 million HIV positive people in sub-Saharan Africa, 5.6 million in South Africa, according to an annual report by UNAIDS.

BEIJING, Dec. 30 (Xinhua) -- China's quality watchdog said Friday that the latest checks by testing organizations did not find excessive levels of aflatoxin in milk products made by Chinese dairies.The special checks were launched after the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) reported on Dec. 23 that two batches of milk products made by two separate domestic dairies, including heavyweight Mengniu Dairy Group, were found to contain high levels of the cancer-causing toxin.A brief statement on the government agency's website Friday said the checks have covered major makers, including Mengniu, Yili Industrial Group, Bright Dairy, and Sanyuan Food.An AQSIQ official said earlier the toxin had originated from cows eating mildewed feed, citing reviews by experts. The toxin would disappear if the animals stop eating the rotten feed, the official said.Aflatoxin is produced by a fungus that commonly grows on crops such as grain and peanuts. High levels of the toxin may lead to cancer in some animals.

BEIJING, Oct. 28 (Xinhua) -- The Chinese government will donate one million U.S. dollars to quake-hit Turkey, Foreign Ministry spokeswoman Jiang Yu announced Friday.Jiang said that China has paid great attention to the situation since a 7.2-magnitude earthquake hit eastern Turkey on Sunday.Jiang noted that Premier Wen Jiabao sent a message of condolence to Turkish Prime Minister Recep Tayyip Erdogan immediately after the quake.The Red Cross Society of China has also donated 50,000 U.S. dollars, and China will continue to offer emergency relief aid to Turkey, she added.According to the Turkish government, as of Friday morning, 570 people were dead and 2,250 injured after the powerful earthquake struck the province of Van in eastern Turkey on Sunday.

HARBIN, Jan. 5 (Xinhua) -- A launching ceremony for the 2012 Sino-Russia Tourism Year was held in northeast China's Heilongjiang province Thursday.The initiative, along with an accompanying initiative to be launched in Russia in 2013, will boost people-to-people exchanges and consolidate Sino-Russian relations, Russian President Dmitry Medvedev said in a statement on Dec. 31, 2011.The initiative is the third of its kind to take place between China and Russia, following Sino-Russia National Year and the Sino-Russia Year of Language held in 2006 and 2009, respectively.The creation of the 2012 Sino-Russia Tourism Year is a vital decision made by leaders of both countries to boost the China-Russia comprehensive strategic partnership of cooperation, said Shao Qiwei, director of China's National Tourism Administration.The tourism year will serve as a platform to display the abundant tourism resources of the two countries, said Grigory Sarishvili, deputy head of the Russia Federal Tourism Agency.Statistics from Russian tourism authorities showed that the number of Chinese tourists to Russia during the first nine months in 2011 saw a year-on-year increase of 52 percent.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."
