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."

NEW DELHI, March 5 (Xinhua) -- Doctors in India have claimed to have successfully performed a rare robotic heart surgery on a 23- year-old person at a hospital in the southern Indian city of Chennai, local media reported Saturday.Dr. R. Ravi Kumar, the Director of the Institute of Cardiovascular Disease at the Chettinad Health City, said the robotically assisted procedure involved replacing both the mitral and the aortal valve simultaneously.The surgery carried out on D. Vijayakanth, an auto driver from Vellore, was done by a three armed robot, took four hours and cost 225,000 rupees (4,500 U.S. dollars)."The best part about using a robot in cardiac surgery is that the patient's heart need not be opened and the surgery can be done using a small 4cm incision. This is not possible with normal surgeries without a robot," Dr Ravi Kumar was quoted by local daily The Times of India as saying.Robotic surgery, which is fairly new in the country, can be used for a gamut of medical procedures, said Dr Ravi Kumar."It requires a lot of precision and intense training because though the robotic hands do the surgery, it has to be controlled by a trained surgeon. One of the biggest disadvantages is the lack of sensory perception which is there when the surgeon actually does the surgery himself," he said.

WINDHOEK, May 21 (Xinhua) -- Top Chinese legislator Wu Bangguo on Saturday met with Namibian President Hifikepunye Pohamba on advancing the bilateral cooperation to further develop the partnership with Namibia.Wu, chairman of the National People's Congress (NPC) Standing Committee, China's top legislative body, extended Chinese President Hu Jintao's greetings to Pohamba and hailed an "all- weather" partnership forged between the two nations.Namibia is one of the youngest states in Africa, which became fully independent in 1990.Wu reviewed the profound friendship between the two countries, which established diplomatic ties one day after Namibia's announcement of its full independence.Wu said the two countries have reaped good harvests in cooperation in the fields of politics, trade, culture, education, public health and culture in recent years, which has already set a model for countries engaged in the South-South cooperation.He also highlighted the mutual understanding and support on issues concerning each other's core interests, and to bring the bilateral economic and trade cooperation to a new high, Wu put forward a three-point proposal concerning the importation of the husbandry and aquatic products, resource and mining as well as the infrastructure construction.Namibia is a nation with significant influence in the southern Africa, Wu said, vowing that China will work with the Namibian side to push the bilateral partnership to a higher level.For his part, Pohamba welcomed Wu's visit, the first one ever paid by a Chinese top legislator, and spoke highly of China's long-standing support for Namibia's national liberation and construction.Namibia will develop the long-term and strategic cooperation in a much broader domain with China and welcomes more Chinese businesses to invest in the country, the Namibian president said.On the China-Afrcia relationship, the two leaders stressed that the two sides should work closer under the framework of the Forum of China-Africa Cooperation to boost political mutual trust, substantial and pragmatic cooperation on trade and humanitarian exchanges, especially those among the young generations, so as to further enrich a new China-Africa partnership.Namibia is the first leg of Wu's 12-day African-Asian tour. He will also visit Angola, South Africa and Maldives.

SAN FRANCISCO, May 26 (Xinhua) -- Internet advertising revenues in the United States surged to 7.3 billion U.S. dollars in the first quarter of 2011, the highest first-quarter revenue level on record for the industry, said a new report released on Thursday.The numbers also represented a 23-percent increase over the same period a year earlier, the Interactive Advertising Bureau ( IAB) and PricewaterhouseCoopers said in the report."The consistent and considerable year-over-year growth we're seeing demonstrates that digital media is an increasingly popular destination for ad dollars, and for good reason," Randall Rothenberg, chief executive officer of the IAB, said in a statement."As Americans spend more time online for information and entertainment purposes, digital advertising and marketing has emerged as one of the most effective tools businesses have to attract and retain customers," he added."These numbers indicate that the interactive advertising field hasn't simply bounced back since the recession; it's growing with dynamic energy," noted David Silverman, a partner at PricewaterhouseCoopers.IAB, a trade association for interactive marketing, comprised more than 500 media and technology companies who are responsible for selling 86 percent of online advertising in the United States.

LOS ANGELES, March 2 (Xinhua) -- Those who take a nap are more likely to have lower levels of blood pressure despite stress, said a new study in the latest issue of International Journal of Behavioral Medicine available on Wednesday.In the study, researchers at Sarah Conklin of Allegheny College in Meadville, Pennsylvania examined 85 healthy university students, who were divided into two groups, with one group taking an hour- long nap during the day, and the other group having no time to sleep. Both groups were given a mental stress test.The study found that participants in both groups experienced increase in blood pressure and pulse rates when they took the stress test, but the average blood pressure of those who slept for at least 45 minutes was significantly lower after the stress test than it was for those who did not sleep.The researchers drew the conclusion that a daytime nap of at least 45 minutes may help stressed-out people lower their blood pressure and protect their heart."Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors," the researchers said in the study."Further research is needed to explore the mechanism by which daytime sleep is linked with cardiovascular health and to evaluate daytime sleep as a recuperative and protective practice, especially for individuals with known cardiovascular disease risk and those with suboptimal sleep quality," they added.Sleep deficiency is common in the United States, posing a long- term health threat. On average, Americans get nearly two hours less sleep a night than they did 50 years ago, according to background information provided by the journal.
