MOSCOW, March 11 (Xinhua) -- A new crew which are to depart for the International Space Station (ISS) at the end of March have successfully passed the pre-flight tests, the Russian Federal Space Agency (Roscosmos) announced on Friday.At a press conference held at Russia's Cosmonauts Training Center, a Roscosmos spokesman said two Russian cosmonauts Andrei Borisenko and Alexander Samokutyaev and a U.S. astronaut Ronald Garn will leave for the ISS by a Russian Soyuz-TM-21 spacecraft on March 30.On March 17, the three crew members and their backup crew members, Anton Shkaplerov, Anatoly Ivanishin and Daniel Burbank, will make their final preparation for the space trip in the Baikonur space site in Kazakhstan.According to the Roscosmos, the three main crew members are expected to spend 170 days in the ISS. During the period, they will receive two U.S. space shuttles and three Russian Progress cargo ships and conduct a spacewalk.The agency also revealed the Soyuz-TM-21 spacecraft scheduled for the ISS was named as Gagarin.The year of 2011 was announced as Russia's Space Year to celebrate the 50th anniversary of the launch of the first Russian manned space flight carrying cosmonaut Yuri Gagarin in 1961 for a 90-minute flight.

WASHINGTON, April 3 (Xinhua) -- Scientists have confirmed that metabolic syndrome, a constellation of conditions that increases the risk of heart disease and diabetes, may also increase the risk of the two most common types of liver cancer, according to data presented at the American Association for Cancer Research's 102nd Annual Meeting 2011, held in Orlando, Florida on April 2-6.Katherine McGlynn, a senior investigator at the National Cancer Institute, said approximately one-third of the U.S. population has metabolic syndrome, which is defined as the co-occurrence of at least three of the following five conditions: raised blood pressure, elevated waist circumference, low HDL or "good" cholesterol, raised triglyceride levels and raised fasting plasma glucose levels.According to McGlynn, persons with these conditions may be at increased risk of developing hepatocellular carcinoma and intrahepatic cholangiocarcinoma.For the current study, researchers identified 3,649 cases of hepatocellular carcinoma and 743 cases of intrahepatic cholangiocarcinoma. They compared the medical history of these patients with the medical histories of 195,953 cancer-free adults.Statistical analyses showed that the persons with liver cancer were significantly more likely than cancer-free persons to have a prior history of metabolic syndrome: 37.1 percent of patients with hepatocellular carcinoma had pre-existing metabolic syndrome, as did 29.7 percent of patients with intrahepatic carcinoma; only 17.1 percent of the cancer-free adults had metabolic syndrome.Liver cancer incidence has been rising since the 1980s in the United States. The factors related to the increase are not well understood. "A lot of attention has focused on viral risk factors, but a significant part of the increase may be due to metabolic syndrome, as well as to diabetes and obesity," said McGlynn."The prognosis for liver cancer is only marginally better than the prognosis for pancreatic cancer, with a five-year survival of approximately 10 percent," she said. "Prognosis is more favorable, however, when liver cancers are diagnosed at early stages when they are small and localized to the liver."

BEIJING, March 3 (Xinhuanet) -- A new study suggested that regular use of painkiller ibuprofen may cut the risk of developing Parkinson's disease, according to Reuters reports.The research findings were published in the online edition of the journal Neurology on Wednesday and later will appear in the print edition on March 8.The study, which followed more than 136,000 U.S. men and women for six years, showed that people who took ibuprofen at least twice a week were 38 percent less likely to develop Parkinson's, a brain disorder that causes tremors and movement problems, compared to those who didn't take the pain reliever so often.Ibuprofen is sold in the U.S. as a non-steroidal anti-inflammatory drug (NSAID). But the study didn't prove that other NSAIDS, like aspirin or naproxen, could also cut the Parkinson's risk."Our study suggests ibuprofen could be a potential neuroprotective agent against Parkinson's," says lead researcher Dr. Xiang Gao from Harvard Medical School, "Protective effects are seen after taking ibuprofen two or more times a week. That's so-called regular use."However, he also warned that no proof has been found that ibuprofen itself can help ward off Parkinson's, and said that it's too early to recommend people to start taking ibuprofen to protect against the disorder.Gao said, "We just see an association, not some causal relationship."Besides, regular ibuprofen use has risks, like stomach bleeding and kidney damage.

LOS ANGELES, March 16 (Xinhua) -- The death rate in the United States reached an all-time low in 2009, dropping 2.3 percent from 2008, a newly released report said.This was the 10th straight year of decline, demonstrating that Americans are living longer than ever, according to the report from the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics.The nation saw a drop from 758.7 deaths per 100,000 people in 2008 to 741 per 100,000 people in 2009 when 2,436,682 deaths were reported, said the report published by HealthDay News on Wednesday.However, life expectancy for blacks remained unchanged -- 70.9 years for men and 77.4 years for women. The disparity between whites and blacks is now 4.3 years, representing a 0.2 percent increase from 2008 to 2009, the report found.The report said that deaths fell in 10 of the 15 leading causes of death -- heart disease dropped 3.7 percent, cancer fell 1.1 percent, and stroke declined 4.2 percent.Deaths from Alzheimer's disease, diabetes, chronic lower respiratory diseases and accidents all declined 4.1 percent, according to the report.Deaths from flu and pneumonia fell 4.7 percent, and deaths from septicemia, a bacterial infection, decreased 1.8 percent, the report said.Deaths from homicides fell 6.8 percent, but suicides increased from 35,933 in 2008 to 36,547 in 2009. Other than suicide, which overtook septicemia as the 10th leading cause of death, the ranking of the leading causes of death was unchanged from 2008 to 2009, the report noted.Infant mortality hit a record low in 2009, falling from 6.59 deaths per 1,000 births in 2008 to 6.42, representing a 2.6 percent decrease, according to the report.The report, however, did not give reasons for these trends.Experts think behavioral changes, particularly the decline in smoking, are partly responsible for the improvements.The report's lead author Kenneth Kochanek, a statistician at the center, said this is preliminary data, and the final data, which should be available this summer, may shed some light on the findings.

GENEVA, May 3 (Xinhua) -- Roughly half to three quarters of adults aged between 18 to 65 years have had headache in the last year, a prevalent problem that went under-treated, the Geneva based World Health Organization (WHO) said in a report issued Tuesday.The report, named "Of Headache Disorders and Resources in the World 2011," regarded headache disorders as one of the most prevalent disorders of mankind.WHO estimated over 10 percent of the adult population suffered from migraine, and 1.7 to 4 percent of them were troubled frequently by headache on 15 or more days every month.Among all cases studied, the report said, on average only 10 percent were treated by neurologists, and the rates were even lower in Africa and South-East Asia.Three types of headache disorders were underlined as the most frequently seen, including migraine, tension-type headache and that caused by medication-overuse.The report concluded that given the very high indirect costs of headache, investment in health care related to headache treatment might be overall cost-saving to society.
