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.

SANAA, Feb. 5 (Xinhua) -- The Somali pirates hijacked a Chinese-flagged commercial ship off Yemen's western city port of al- Hudaida in the Red Sea, Chinese military attache to Yemen confirmed to Xinhua on Saturday.The Chinese military confirmed that the Chinese-flagged commercial ship, which was registered in Hongkong, China, had been hijacked by the Somali pirates off the Yemeni coast, Chinese military attache to Yemen told Xinhua.The ship was then moved by the pirates towards the Somali coasts, he added, without providing how many people were on board or the date of the hijack.Earlier, Yemeni Interior Ministry said the Chinese ship called "Tien Hau" was attacked by the pirates some 11 nautical miles (20. 4 kilometers) off the Yemeni island of Al-Tair off the city port of al-Hudaida.Meanwhile, a security source at the ministry told Xinhua "the security operation room of the ministry received unconfirmed information that an anti-piracy international navy fleet might intercept the pirates and help release the Chinese ship.""We are following up the situation to confirm the release of the Chinese ship, as coast guard boats were dispatched to track the ship and pirates," he told Xinhua on condition of anonymity."The hijack took place early today, but we do not have exact information about the number of the ship's crew," he added.The Gulf of Aden is considered as one of the world's most dangerous waters because of rampant piracy.

WASHINGTON, May 27 (Xinhua) -- The U.S. Treasury Department said in a report released on Friday that China was not manipulating its currency."In China, since the authorities decided in June 2010 to allow the exchange rate to appreciate in response to market forces, the renminbi (RMB) has appreciated by a total of 5.1 percent against the dollar in nominal terms through the end of April 2011, or at an annual pace of approximately 6.0 percent," noted the semi- annual report on international economic and exchange rate policies.The Treasury said that as inflation in China is significantly higher than it is in the United States, the renminbi has appreciated more rapidly against the dollar on a real, inflation- adjusted basis, at a rate of around 9 percent per year.The delayed report, which was originally scheduled to be sent to the Congress on April 15, finds "no major trading partner of the United States" manipulated its currency during the period covered in the report.The Treasury added that it will continue to "closely monitor" the renminbi appreciation pace.The report also noted that the U.S. economy is recovering from its deepest recession in the post-war period."While recent growth is encouraging, the economy still faces significant challenges," said the report. The number one challenge is still in the labor market.The U.S. unemployment rate, currently at 9.0 percent, is not expected to fall significantly this year.Besides, housing market and long-term fiscal position are " unsustainable," according to the report.In recent remarks, Treasury Secretary Timothy Geithner stated that China is the fastest growing market for U.S. exports. In 2010, U.S. exports to China grew at a pace that was 50 percent higher than the rest of the world.

UNITED NATIONS, Feb. 11 (Xinhua) -- China Friday urged the United Nations and Security Council to give more attention to Africa and called on the international community to provide greater support to the region in order to maintain peace and security. Addressing an open debate of the UN Security Council on the interdependence between security and development, Li Baodong, China's permanent representative to the UN said the inter-linkages between peace and development are most pronounced in Africa. There will be no world prosperity and stability without peace and development in the region. He called on the international community to provide greater support and more assistance to regional countries, AU and other regional and subregional organizations to maintain African peace and security. Li stressed that security and development are mutually linked and reinforcing. To safeguard peace and promote development, the international community should increase development input and eradicate root causes of conflicts. "Poverty and underdevelopment are the major causes for triggering conflicts and breeding terrorism. The developed countries should further increase its development aid, provide debts relief to developing countries, open up markets, transfer technology and help the developing countries to achieve the Millennium Development Goals as soon as possible." Li said development can be anchored only in an environment free from war and turbulence. The UN and Security Council should vigorously promote peaceful culture, encourage and support peaceful resolutions to disputes through dialogue, consultations and good offices. In addition, greater emphasis should be given to peacebuilding so as to prevent relapse into conflicts. "In post-conflict countries and regions, simultaneous progress should be made in the fields of politics, security and development throughout development and reconstruction process, " said Li. "Capacity building should be prioritized in the post-conflict countries to enhance governance, provide basic services, advance development and reconstruction so that the people could enjoy peaceful 'dividend' quickly. This is conducive to consolidating political reconciliation process and stabilizing post-conflict situations, " he said.
