LOS ANGELES, April 6 (Xinhua) -- Freeze-dried strawberries may play a role in the prevention of esophageal cancer, a new study suggests."Strawberries may be an alternative or work together with other chemopreventive drugs for the prevention of esophageal cancer," said lead researcher Tong Chen, M.D., Ph.D., assistant professor, division of medical oncology, department of internal medicine at the Ohio State University.Study findings were presented at the ongoing 102nd annual meeting of the American Association for Cancer Research (AACR) in Orlando, Florida, according to the American Association for the Advancement of Science (AAAS) on Wednesday."We concluded from this study that six months of eating strawberries is safe and easy to consume. In addition, our preliminary data suggests that strawberries can decrease histological grade of precancerous lesions and reduce cancer- related molecular events," said Chen, who is also a member of the Molecular Carcinogenesis and Chemoprevention Program in the Ohio State University Comprehensive Cancer Center.The study involved a group of participants who consumed 60 grams of freeze-dried strawberries daily for six months and completed a dietary diary chronicling their strawberry consumption.The researchers obtained biopsy specimens before and after strawberry consumption. The results showed that 29 out of 36 participants experienced a decrease in histological grade of the precancerous lesions during the study.Using freeze-dried strawberries was important because by removing the water from the berries, they concentrated the preventive substances by nearly 10-fold, Chen said.Esophageal cancer is the third most common gastrointestinal cancer and the sixth most frequent cause of cancer death in the world, she noted.Chen and her team are studying esophageal squamous cell carcinoma (SCC) which makes up 95 percent of cases of esophageal cancer worldwide. China, where this study took place, has the highest incidence of esophageal SCC, according to the AAAS.In a previous study, Chen and colleagues found that freeze- dried strawberries significantly inhibited tumor development in the esophagus of rats. Based on these results, they embarked on a Phase Ib trial that included participants with esophageal precancerous lesions who were at high risk for esophageal cancer."Our study is important because it shows that strawberries may slow the progression of precancerous lesion in the esophagus," Chen said.But she said they need to test this in randomized placebo- controlled trials in the future.

WASHINGTON, May 25 (Xinhua) -- The number of young adults in the United States with high blood pressure may be much higher than previously reported, according to a new study by researchers at the University of North Carolina (UNC) at Chapel Hill.Researchers analyzed data on more than 14,000 men and women between 24 and 32 years old in 2008 from the National Longitudinal Study of Adolescent Health, known as Add Health. They found 19 percent had elevated blood pressure, also referred to as hypertension. Only about half of the participants with elevated blood pressure had ever been told by a health-care provider that they had the condition."The findings are significant because they indicate that many young adults are at risk of developing heart disease, but are unaware that they have hypertension," said Quynh Nguyen, a doctoral student at UNC's Gillings School of Global Public Health and the study's lead author. Hypertension is a strong risk factor for stroke and coronary heart disease, the leading cause of death for adults in the United States.The findings were published this week in the journal Epidemiology.Kathleen Mullan Harris, Add Health's principal investigator and a co-author of the paper, said the findings were noteworthy because they were from the first nationally representative, field- based study of blood pressure to focus on young adults."The message is clear," said Harris. "Young adults and the medical professionals they visit shouldn't assume they're not old enough to have high blood pressure. This is a condition that leads to chronic illness, premature death and costly medical treatment."

SAN FRANCISCO, April 19 (Xinhua) -- YouTube announced Tuesday that the much-anticipated British royal wedding of Catherine Middleton and Prince William will be live streamed on the website' s live channel.Next Friday, the live stream will follow the wedding procession, marriage ceremony at Westminster Abbey and balcony kiss, said YouTube in its official blog. The official channel (www.youtube. com/theroyalchannel), will have live blog commentary of the event, and users can also upload video wishes for the couple on the site."This one is already heralded as the first of the Internet age, where for the first time in thousands of years of royal history, the moment will be captured on-line and preserved forever," said the blog post.YouTube, whose parent company is Google, will provide the technical support for the broadcast and the footage will be provided by the BBC.On April 8, YouTube launched live streaming service YouTube Live, including a home page where users can view live events and a live steaming platform on which partners with accounts could stream live content.

BEIJING, April 12 (Xinhuanet) -- Doctors may choose riskier treatment with fewer severe side effects for themselves than they'd recommend for their patients, according to a study in the Archives of Internal Medicine Tuesday. In the study, two sets of questions were sent to primary care physicians around the United States. One involved choosing between two types of colon cancer surgery and the other situation involved choosing no treatment for the flu, or choosing a made-up treatment less deadly than the disease but which could cause permanent paralysis. Of 242 physicians who answered the colon cancer questionnaire, 38 percent went with the treatment that carried a higher risk of death but fewer side effects for themselves. By contrast, only a quarter said they would recommend that treatment to their patients.In the flu scenario, 63 percent chose the deadlier option of no treatment for themselves, versus 49 percent recommending it for patients.The findings are important because patients faced with difficult medical decisions often ask their doctors, "What would you do?" The answer reflects the doctors' values -- not necessarily those of the patients.Doctors should know what their patients value most before giving advice, and patients should ask doctors the reasons behind their answers, said study author Dr. Peter Ubel, an internist and behavioral scientist at Duke University.

NEW YORK, April 13 (Xinhua) -- New York City Mayor Michael Bloomberg and former U.S. President Bill Clinton announced on Wednesday the merger of their environmental groups, hoping to make it the most prominent climate policy organization in the world.The new organization would combine C40, a coalition of international cities run by Bloomberg, and the Clinton Climate Initiative, a project of Clinton' s philanthropic foundation, into a single organization, which will focus on population-rich cities to address global warming."I am elated by this. I think we really have a chance to make a difference," said Bill Clinton during a press conference at Gracie Mansion, adding that "together we are proving it is possible to create jobs and grow economies through reduced emissions."C40 and the Clinton Climate Initiative both seek to cut carbon emissions through programs that reduce energy use in buildings, promote mass transit and reuse greenhouse gases emitted by landfills.The newly combined organization is said to have a budget of about 15 million U.S. dollars. The group will have main offices in New York, Los Angeles and London.
