WASHINGTON, April 13 (Xinhua) -- The U.S. Food and Drug Administration (FDA) announced on Wednesday that it has approved the cPAX Aneurysm Treatment System for surgery on brain aneurysms that are difficult to manage because of their size and shape.An aneurysm is a bulge in the wall of a blood vessel, which can rupture as it increases in size, causing hemorrhage or death. Brain aneurysms often produce no symptoms until they grow and press on nerves in the brain, or until they begin to leak blood or rupture.Aneurysms can be repaired in two ways: surgeons can close the base of the aneurysm with a surgical clip, or use a technique commonly known as coiling, in which surgeons use a catheter to thread metallic coils through a blood vessel in the groin and into the blood vessel in the brain that contains the aneurysm. Surgeons then fill the aneurysm with the detachable coils, which block it from circulation and cause blood to clot, effectively destroying the aneurysm.Aneurysms larger than 10 millimeters are difficult to treat with clipping or coiling. The cPAX device system is indicated for use in those brain aneurysms."Like coiling, the cPAX Aneurysm Treatment System is a form of endovascular repair," said Christy Foreman, director of the Office of Device Evaluation in the FDA's Center for Devices and Radiological Health. "But instead of tiny metallic coils, it uses a special polymer material to fill the space within the aneurysm."According to the FDA, the cPAX device system is indicated for use in adults aged 22 and older and should not be used in patients with an active infection or in those in whom anticoagulation and antiplatelet therapy is contraindicated.

BEIJING, Feb. 8 (Xinhua) -- China's aviation authorities announced on Tuesday that more passengers traveled by air during the Spring Festival holidays, with Chinese airlines handling some 5.07 million passengers during the period.The number of passengers on flights during the Chinese Lunar New Year holidays, which ended Tuesday, was up 6 percent from the same period last year, according to the Civil Aviation Administration of China (CAAC).On average, 72 percent of the seats on flights across the country were loaded during the holiday travel season, up 2 percentage points from the same period last year, according to the CAAC.To prepare for the holiday travel surge, the CAAC arranged 38,992 flights during the holidays, including eight chartered flights to Egypt to fly home 1,796 Chinese travelers stranded amid massive protests in the African country.

CANBERRA, April 14 (Xinhua) -- The Australian federal government could struggle to get its carbon tax through parliament, as key independent Member of Parliament (MP) Tony Windsor on Thursday warned the plan may never become a reality.Windsor, who is one of the independents Prime Minister Julia Gillard will rely on to get her carbon tax pass the Parliament, said while climate action will benefit the bush, he will not "vote for something that does nothing"."There is no carbon tax, there may not be a carbon tax," he told ABC News on Thursday morning."The prime minister doesn't have the numbers, as I understand it at the moment."I have a vote, others do as well, so you can never guarantee something before it gets through a minority parliament."Windsor said people in his rural New South Wales electorate were concerned about the lack of detail around the proposed carbon tax.Gillard played down his comments, saying that Windsor, who sits on the multi-party climate change committee, had been "perfectly consistent" in his approach to the carbon price debate."He does believe climate change is real ... that pricing carbon is the best way, an important way, of tackling climate change," Gillard told ABC Radio on Thursday."(But) he's going to look at the (legislative) package and wait to the end and then judge (it)."Gillard added that the Labor government remains determined to introduce a carbon tax from mid-2012 followed by an emissions trading scheme.

LOS ANGELES, April 10 (Xinhua) -- Drinking green tea and practicing Taichi may promote bone health of postmenopausal women and reduce the risk of inflammation, a new study suggests.The study, conducted by researchers at the Laura W. Bush Institute for Women's Health at the Texas Tech University Health Sciences Center, focused on postmenopausal women and investigated the potential for green tea to work synergistically with Taichi in enhancing bone strength of postmenopausal women.Originating as a martial art in China, Taichi is a mind-body exercise that utilizes slow, gentle movements to build strength and flexibility, as well as deep breathing and relaxation, to move qi, or vital energy, throughout the body.The study findings were published Sunday at EurekAlert.org, the website of the American Association for the Advancement of Science (AAAS).Carried out as a double-blind, placebo-controlled, intervention trial (the "holy grail" of scientific studies), this experiment involved 171 postmenopausal women with the average age of 57 who had weak bones but not full-fledged osteoporosis. Subjects were divided into 4 groups -- placebo: starch pill (placebo) and no Taichi; GTP or green tea polyphenols (500 mg/day) and no Taichi; Placebo plus Taichi (starch pill and practising Taichi three times a week); and GTP plus Taichi.The study lasted for 6 months, during which blood and urine samples were collected and muscle strength assessed.The results show that consumption of GTP (at a level equivalent to about four-six cups of steeped green tea daily) and participation in Taichi independently enhanced markers of bone health by three and six months, respectively. A similar effect was found for muscle strength at the 6-month time point. Participants taking Taichi classes also reported significant beneficial effects in quality of life in terms of improving their emotional and mental health.Perhaps most remarkable, however, was the substantial effect that both GTP and Taichi had on biological markers of oxidative stress. Because oxidative stress is a main precursor to inflammation, this finding suggests that green tea and Taichi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well.In the study, the researchers developed an animal model (the ovariectomized, middle-aged female rat), with which they could effectively study the effects of green tea consumption on protection against breakdown of the bone's microarchitecture, according to the AAAS.In humans, this can lead to osteoporosis, a condition common to older women. The researchers say what they have learned from the animal models might also be applicable to postmenopausal women.There is a "favorable effect of modest green tea consumption on bone remodeling in this pre-osteoporotic population," said lead researcher Dr. Chwan-Li (Leslie) Shen, an associate professor at the institute.The researchers plan to soon complete a more long-term study utilizing more technically savvy measures of bone density, according to the AAAS.
