LOS ANGELES, April 4 (Xinhua) -- A woman's breast milk cells may be used to predict cancer in future research, according to a study published by HealthDay News on Monday.In the study, researchers at the University of Massachusetts in Amherst collected breast milk from 271 women in the United States. All had either undergone a biopsy of the breast to check for cancer, or were scheduled for one.The researchers evaluated breast milk samples from the biopsied and non-biopsied breasts.The researchers first isolated potentially cancerous cells, known as epithelial cells, and then isolated DNA to look for signals that regulate tumor suppresser genes.In the next step, the researchers analyzed three genes among the many known to undergo a process called methylation in breast cancer. Methylation in a specific region of a gene can inhibit or suppress the expression of a gene.For one gene, SFRP1, the average methylation was higher in the biopsied breast, the study found.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast.Among the women whose biopsies detected cancer, average methylation of the RASSF1 gene in the biopsied breast was considerably higher compared to the non-biopsied breast."It looks as if we can use the cells from breast milk to assess breast cancer risk," said Dr. Kathleen Arcaro, an associate professor of veterinary and animal sciences at the university.It's too soon, however, to assess the cancer detection rate associated with breast milk cell examination, she said."We can't say at this point for two reasons," she said. "One is, we need long-term follow-up. And the second really important reason is, we need to sample a larger panel of genes."Arcaro is to present her findings later Monday at the annual meeting of the American Association for Cancer Research in Orlando, Florida, according to HealthDay News.

HOUSTON, May 2 (Xinhua) -- The Offshore Techonology Conference, one of the world's largest offshore technology shows, kicked off here Monday.The five-day event, which attracted an estimated 72,000 victors from all around the world, not only provided a platform for the about 2,400 participating companies from 40 countries to lure visitors with their newest products and technologies, but also for the them to share insights and discuss issues the industry is facing.On Monday, a number of companies, including Halliburton and Baker Hughes, received the Spotlight on New Technology Award by the OTC for their new products and solutions.Founded in 1969, the annual Offshore Technology Conference is the world's foremost event for the development of offshore resources in the fields of drilling, exploration, production, and environmental protection. OTC is held annually at Reliant Center in Houston.

BEIJING, Feb. 26 (Xinhua) -- China's Ministry of Education said Friday that 34.29 million students graduated from the country's higher-learning institutions between 2006 and 2010.Xu Mei, the ministry's spokeswoman, said the number is even more than that of the graduates in the 20 years prior to 2006 combined."During the 11th five-year plan period (2006-2010), higher education has become even more accessible to the general public. Higher-learning institutions provide a strong support of brain power and human resources to the social and economic development," Xu said.The "Outline of China's National Plan for Medium and Long-Term Education Reform and Development (2010-2020)," which was publicized last year, says "the strategic goals to be attained by 2020 are to basically modernize education; shape a learning society; and turn China into a country rich in human resources."

MOHE, Heilongjiang, Feb. 3 (Xinhua) -- Some 1.318 million tonnes of crude oil had flowed through an oil pipeline from Russia's far-east to China by Jan. 31, a month after the pipeline began operating, an officer of the Chinese operator of the pipeline said.The pipeline, which originates in the Russian town of Skovorodino in the far-eastern Amur region, enters China at Mohe and terminates at Daqing City of northeast China's Heilongjiang Province.The facility withstood the test of the severe coldness since it was put into operation on Jan. 1 and no production accident has been reported so far, said Gou Hanghai, director of the Mohe administration station of the pipeline.The pipeline remains a daily oil delivering capacity of 42,000 tonnes, he saidThe 1,000-km-long pipeline will transport 15 million tonnes of crude oil from Russia to China per year from 2011 to 2030, according to an agreement signed between the two countries.Some 72 kilometers of the pipeline is in Russia and 927 kilometers of it is in China.

LOS ANGELES, March 27 (Xinhua) -- Walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut, U.S. researchers have found.Study findings were presented on Sunday at the 241st National Meeting & Exposition of the American Chemical Society (ACS) in Anaheim, Southern California.Nuts contain plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free, ACS researchers said in the study.Moreover, nuts contain healthful polyunsaturated and monosaturated fats rather than artery-clogging saturated fat, according to the study.The researchers based their conclusion on analysis of antioxidants in nine different types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias and pecans.They found that walnuts have the highest levels of antioxidants, with plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free.The latest study adds more evidence that walnuts are top nuts for heart-healthy antioxidants, the researchers said.Previous studies showed that regular consumption of small amounts of nuts or peanut butter can decrease the risk of heart disease, certain kinds of cancer, gallstones, Type 2 diabetes, and other health problems.But the latest study is the first to compare both the amount and quality of antioxidants found in different nuts."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who led the latest study."A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."
