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.

BEIJING, Feb. 24 (Xinhua) -- Chinese Premier Wen Jiabao attended the opening ceremony of the China-EU Year of Youth in Beijing on Wednesday, encouraging young people from China and the EU to build a brighter future for bilateral strategic partnerships.Joining over 500 young people from China and the EU in the Capital Museum in downtown Beijing, Wen said that the year-long youth exchange campaign was the first theme year between China and the EU since the establishment of diplomatic ties, and is also the largest-ever China-EU cultural exchange program."This has revealed that our relations will be more vibrant in the future and full of hopes," he added.China and the EU are in a vital period for deepening cooperation, Wen said, calling on young people from both sides to consider and explore ways to share opportunities, meet challenges and seek common development, which has benefits for China, the EU and the world.Wen hopes that young people from both sides would always be brave in pursuing innovation and the truth. He also encouraged them to learn from each other in a frank and open spirit, in a bid to jointly create a better future for China-EU ties.A video speech from European Commission President Jose Manuel Barosso was aired at the ceremony. He said that the Year of Youth offers an interactive platform for European and Chinese young people to enhance mutual understanding and friendship and also inject vitality to China-EU relations.Premier Wen and Barroso jointly initiated The China-EU Year of Youth during the 12th EU-China summit held in 2009.Along with the opening ceremony in Beijing, Chinese and European youth were immersed in two-day discussions on topics such as culture, education, volunteering, creativity and environmental protection starting on Tuesday."We had excellent discussions on possible cooperation projects, ranging from environmental protection, world heritage to art and intellectual property," said Pierre Arlaud, a member of an EU youth delegation that arrived in Beijing on Monday to participate in the opening ceremony."I can feel there is a strong will from both sides to deepen understanding and forge a stronger partnership," he added.The opening ceremony was the first in a series of exchange activities that will be held throughout the year in China and Europe. The events include cultural seminars, volunteer service conferences, youth summer camps and TV debates.The year-long program was co-hosted by the All-China Youth Federation and the European Commission. The initiative aims to promote intercultural dialogue and strengthen mutual understanding and friendship between young people in China and the EU, as well as encouraging them to support the development of China-EU relations.

JAKARTA, April 27 (Xinhua) -- Marine scientists will begin conducting an ecological survey in eight locations throughout the resort island in Indonesia's Bali province that could be developed as marine managed areas due to their biodiversity and coral structure, the Jakarta Post quoted an expert as saying on Wednesday.The survey, which will take place from April 29 to May 11, will be carried out by four international scientists and local scientists from universities.Ketut Sarjana Putra, the marine program director with Conservation International Indonesia, said Tuesday the survey was aimed at identifying marine species and their population in each of the eight locations.Selected from 25 potential marine conservation zones, the eight locations are Pulaki and Pemuteran, Lovina, Les Village, Tulamben and Amed, Padangbai, Nusa Penida, Bukit Uluwatu Peninsula and Perancak Beach. "We will go around Bali, starting from Sanur in the south, heading east, then covering the northern and the western areas, then back to the south," Ketut told the daily.The survey is part of a process to build a network of marine protected areas to effectively manage the island's marine and coastal resources to sustain environmental and socioeconomic value and benefits, with priority given to the eight locations.
