BEIJING, May 19 (Xinhuanet) -- LinkedIn said Wednesday that its stock will debut at 45 U.S. dollars per share, a higher price than the company was expecting even earlier this week, media reports said.The first major U.S. social networking firm to go public, LinkedIn jacked up its initial public offering (IPO) share price for 7.84 million shares to 45 dollars just a week after it first set a target of 32-35 dollars per share.It minted LinkedIn with a market value of more than 4 billion dollars, the highest for a U.S. Internet company taking its first bow on Wall Street since Google Inc. went public nearly seven years ago.The sale could bring in more than 354 million dollars. The company's shares are expected to begin trading on the New York Stock Exchange on Thursday under the symbol "LNKD".LinkedIn has more than 100 million members in over 200 countries and territories. In 2010, the company made 15 million dollars in profit on 243 million dollars in revenue, according to its SEC filing.LinkedIn's biggest shareholder is its founder and chairman, Reid Hoffman, who owns more than 21 percent of the company.

LOS ANGELES, April 2 (Xinhua) -- People taking antidepressants may be more likely to develop thicker arteries which may raise the risk of heart disease and stroke, a new study suggests.Depression can heighten the risk for heart disease, but the effect of antidepressant use is separate and independent from depression itself, according to the study make public by the American Association for the Advancement of Science (AAAS) on Saturday.The data suggest that antidepressants may combine with depression for a negative effect on blood vessels, said study first author Amit Shah, MD, a cardiology fellow at Emory University School of Medicine.Study findings will be presented on April 5 at the American College of Cardiology meeting in New Orleans, according to the AAAS.The study included 513 middle-aged male twins who both served in the U.S. military during the Vietnam War. Twins are genetically the same but may be different when it comes to other risk factors such as diet, smoking and exercise, so studying them is a good way to distill out the effects of genetics.Researchers measured carotid intima-media thickness - the thickness of the lining of the main arteries in the neck -- by ultrasound. Among the 59 pairs of twins where only one brother took antidepressants, the one taking the drugs tended to have higher carotid intima-media thickness (IMT), even when standard heart disease risk factors were taken into account.The effect was seen both in twins with or without a previous heart attack or stroke. A higher level of depressive symptoms was associated with higher IMT only in those taking antidepressants."One of the strongest and best-studied factors that thickens someone's arteries is age, and that happens at around 10 microns per year," Shah said. "In our study, users of antidepressants see an average 40 micron increase in IMT, so their carotid arteries are in effect four years older."Antidepressants' effects on blood vessels may come from changes in serotonin, a chemical that helps some brain cells communicate but also functions outside the brain, Shah said."I think we have to keep an open mind about the effects of antidepressants on neurochemicals like serotonin in places outside the brain, such as the vasculature. The body often compensates over time for drugs' immediate effects," Shah said. " Antidepressants have a clinical benefit that has been established, so nobody taking these medications should stop based only on these results. This isn 't the kind of study where we can know cause and effect, let alone mechanism, and we need to see whether this holds up in other population groups."

ABUJA, Jan. 28 (Xinhua) -- China and Nigeria celebrated the 40th anniversary of the establishment of diplomatic relations on Thursday evening in Nigeria's capital city Abuja.More than 600 Chinese and Nigerian guests, including Nigeria's former Head of State Yakubu Gowon, attended the gala event.On Feb. 10, 1971, the two most populous developing countries in Asia and Africa set up their diplomatic relations, said Deng Boqing, the Chinese ambassador to Nigeria.The frequent high level visits from both sides built up the mutual trust, the exchanges and cooperation in the fields of economy, culture, science, education and health, he said.The bilateral trade volume in 2010 is expected to break the record 7.5 billion U.S. dollars in 2008. The total Chinese investment in Nigeria has been nearly 8 billion dollars by the end of 2010, he said.Deng also gave tribute to the indispensable efforts made by the overseas Chinese and Chinese companies in Nigeria.Yakubu Gowon, former head of state in the 1970s, told Xinhua that he was delighted to witness the establishment of diplomatic ties between China and Nigeria in 1971 during his term. He visited China and met the late Chinese leader Mao Zedong in 1974.Nigeria's President Goodluck Jonathan sent his representative to the celebration of the 40th anniversary of bilateral ties, pledging the two countries would work closely in the future.

WASHINGTON, March 30 (Xinhua) -- A trace amount of radioactive iodine has been found in a sample of milk from the west state of Washington, the U.S. Environmental Protection Agency and the Food and Drug Administration (FDA) said Wednesday.According to a joint statement from the two agencies, results from a screening sample taken March 25 from Washington detected 0.8 pCi/L of iodine-131, which is more than 5,000 times lower than the Derived Intervention Level set by the FDA.These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children, the statement said.Iodine-131 has a very short half-life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly."Radiation is all around us in our daily lives, and these findings are a minuscule amount compared to what people experience every day. For example, a person would be exposed to low levels of radiation on a round trip cross country flight, watching television, and even from construction materials," said Patricia Hansen, an FDA senior scientist.
