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."

CAPE TOWN, April 30 (Xinhua) -- The World Economic Forum on Africa, scheduled on May 2-4 in Cape Town, South Africa, will see participants exchange views on how the continent can turn to the next chapter of development.The meeting, expected to gather a record 900 participants from over 60 countries, will be held under the theme "From Vision to Action, Africa's Next Chapter," organizers said."We chose this theme because we feel it is very relevant for the events that are taking place on this continent, and the opportunity for growth and investment that the international and African communities are seeing," said Katherine Tweedie, head of Africa for the World Economic Forum.Seven of the fastest growing economies in the world in the next five years will be in sub-Saharan Africa, Tweedie noted, saying that a lot of discussion will be devoted to explore drivers behind this growth.Africa's economic growth in recent years have impressed the world. Though being the most underdeveloped continent, Africa have been more resilient than expected during the global economic crisis.The International Monetary Fund (IMF) have predicted that the continent's growth in 2011 will reach 5.3 percent.Under one of the three thematic pillars, "Shaping Africa's Role in the New Reality," the meeting will explore how Africa can take on a leadership role in the new reality and guard against newly emerging global and regional risks. Participants will look at how Africa can strengthen its representation and negotiation capacity on global platforms such as COP 17 and the G20.Meanwhile, the meeting will look into Africa's industrial diversification, which is widely considered as an effective way to increase competitiveness. Discussions under the thematic pillar of "Fostering Africa's News Champions of Growth" will focus on what innovative and entrepreneurial lessons drive Africa's fastest- growing companies, and how can Africa's emerging economies build capacity in science, technology and innovation to move up the value chain.Another topic expected to attract much attention is Africa's inclusive development. In recent years, African decision makers have been looking for ways to attain inclusive development by translating economic growth into better lives for the people.Marcus Courage, managing director of consulting group Africapractice, said ahead of the meeting that Africa must start measuring its economic growth in terms of job creation and progress of value addition of what it produces, rather than the gross domestic product (GDP), if it has to move from vision to action."One of the challenges is that we measure economic success in therms of GDP. That is not fair reflection of action," he told Xinhua.Under the thematic pillar of "Building Partnership for Inclusive Development," participants will debate on how can inclusive growth be put at the heart of a sustainable development agenda for Africa, and how can government of African countries work together with the business sector to distribute more equitably the benefits from the wealth in natural resources, among others.Regarding the highlight of this year's meeting, Tweedie said there will be a strong focus on green growth and the environment agenda, working closely with the South African government, given that South Africa will be hosting the COP 17 meetings in December.The meeting will also have very strong representation from Francophone west Africa for the first time. As a result a good part of the discussions will be focusing on issues taking place in this part of Africa, she added.Although South Africa has hosted the World Economic Forum on Africa for a number of times, this year the host is attracting particular attention.South Africa has joined the BRICS group of countries which also include Brazil, Russia, India and China, becoming the only African member in the grouping. It is also the only country from Africa in G20. In November this year, South African city of Durban will host the 17th Conference of the Parties (COP 17) to the UN Framework Convention on Climate Change.How can the country speak for Africa in the international arena, and what role can it play in facilitating closer cooperation between developing countries is also expected to draw in-depth discussions at the meeting.Meanwhile, participants are also expected to exchange views on issues including Africa's agriculture development, infrastructure construction, China-Africa cooperation, impact of political situation in North African and the Middle East on Africa's economic development, among others.

MOSCOW, Feb. 9 (Xinhua) -- China's steady economic rise causes both high hopes and anxiety among world leaders, but a Russian expert believes China's peaceful development is an opportunity for the entire world.Yakov Berger of the Far East Institute of the Russian Academy of Sciences told Xinhua that China's policy of peaceful development is a strategic choice, aimed at long-term and sustainable growth."China overcame the global financial crisis, decreased poverty, and increased people's wealth," Berger said."Still, many important tasks for China remain to be fulfilled and first of all, modernization, industrialization and urbanization. This is why China needs strong and long-lasting peace," he said.Berger said China's policy of peaceful development has already won support from the majority of countries, so they are willing to cooperate with the world's most powerful developing nation."China's peaceful development gives chance to all people in the world, as China became the main engine of the global economic development. Many developed countries are gravitated to China because they depend on Chinese supplies and the Chinese market," Berger said.However, although some countries are aware that China's sustainable growth requires peace and stability, some eye China's growing influence as negative, the professor said.Berger said that Beijing tries to persuade Washington that China's rise does not threaten American security. The question, then, is to what degree is the U.S. ready to accept the new reality, Berger said.Berger cited two main reasons why some Western politicians don't trust Beijing."First, this is a natural response from the people who got used to a certain world order," he said, "Such an order implies the existence of the so-called 'golden billion' people who have access to all of civilization's benefits while the other five billion can't make ends meet."Berger said that when China attempts to achieve the same living standards, that induces some fears based on the notion that the Earth resources are limited.Berger believed the second reason is xenophobia and racism, which generates talk about the "Chinese threat.""But they talked about the 'China threat' even in times when China used to be an underdeveloped nation," Berger noted.

BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.
