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.

BEIJING, Feb. 17 (Xinhua) -- China's new rules for reviewing proposed mergers and acquisition (M&A) deals by foreign firms on grounds of national security would benefit both Chinese and foreign investors, a Ministry of Commerce (MOC) spokesman said Thursday.The rules will facilitate the growth of foreign-invested enterprises (FIEs) in China and improve the quality and structure of foreign direct investment (FDI) flowing into China, MOC spokesman Yao Jian said at a press conference.The move also marked an improving legal environment for the security of China's business sector along with its opening-up drive, given that M&A by FIEs will increasingly become a trend in the coming years, Yao said."The adoption of the rules in China will also increase policy transparency and improve law-based government administration," said Yao.Yao's words came after the State Council, China's Cabinet, announced last Saturday that it was establishing a panel to check whether M&A deals struck by foreign firms in the country endanger national security.The panel will review attempts by FIEs to buy or merge with domestic companies whose business pertains to national defence, agriculture, energy, resources, key infrastructure, transport systems, key technology sectors and important equipment manufacturing industries, according to a statement published on the central government's website www.gov.cn.The review will be conducted by a foreign investment security review board under the cabinet, members of which come from the National Development and Reform Commission (NDRC), the MOC and other agencies.The new regulations, which take effect in March, come at a time when China is expected to see more M&A deals struck by foreign firms.Currently, inward M&A accounts for about 3 percent of China's total FDI, a sharp contrast with the global average level of more than 70 percent, said Yao. "M&A by FIEs will become a major trend in China."China's taking in FDI through more M&A will promote industrial consolidation and restructuring, and it will also mean more efficient utilization of the existing resources, he said."As the share of M&A in the FDI will probably rise from the current 3 percent to 8 percent, 10 percent or even more, it is necessary to timely formulate China's own rules governing foreign takeovers in line with international standards," Yao said.In April 2010, the State Council said in a statement that foreign investment should be allowed to be more diversified and foreign investors encouraged to participate in the consolidation and restructuring of domestic firms via equity holdings or acquisitions.He Manqing, a researcher with the Chinese Academy of International Trade and Economic Cooperation of the MOC, said "It is right and proper to impose regulations and requirements on proposed M&A deals in the sectors of strategic importance and those involving national security.""The introduction of the regulations conforms to the new trend in China's receiving of FDI and indicates that China's regulations on FDI are becoming more mature," said He.The NDRC said Wednesday that national security scrutiny would only occur when foreign companies take a majority stake in a domestic M&A deal, meaning that a minority stake purchase will not trigger a review."The new rules draw references from similar rules in the United States, Germany and Canada," the NDRC said in a statement on its website.The NDRC also said that the new regulations were in line with World Trade Organization rules and did not imply that China had changed its policies on opening up and attracting FDI.China's FDI jumped 23.4 percent in January to 10.03 billion U.S. dollars, said Yao. The monthly growth rate was up from December's 15.6 percent.As the world's top investment destination, China received a total of 105.74 billion U.S dollars in FDI in 2010, up 17.4 percent year on year, the MOC said last month.

BEIJING, Feb. 3 (Xinhua) -- Chinese Foreign Ministry said here Thursday that almost all Chinese travellers stranded in Egypt had returned home by planes sent by the government.A total of 1,848 Chinese, including those from Hong Kong, Macao and Taiwan, had been flown back by Thursday afternoon, the ministry said in a statement.The Chinese government has organized eight flights from four Chinese airline companies to Egypt since Jan. 31.The last two planes, belonging to China Eastern Airlines, returned to Beijing from Egypt Thursday, bringing back a total of 431 Chinese citizens, according to the ministry.

BEIJING, April 14 (Xinhuanet) -- The discovery of a sharp-toothed dinosaur fossil in New Mexico, the United States, may bridge a gap in the evolution of the species, researchers said in Wednesday's journal Proceedings of the Royal Society B.Researchers from the Smithsonian Institution unearthed the dinosaur skull and neck vertebrae in Abiquiu, New Mexico, where it had remained buried for around 230 million years. The short snout and slanting front teeth of the find — Daemonosaurus chauliodus — had never before been seen in a Triassic era dinosaur, said Hans-Dieter Sues of the Smithsonian's National Museum of Natural History.Sues, curator of vertebrate paleontology at the museum, said the discovery helps fill the evolutionary gap between the dinosaurs that lived in what is now Argentina and Brazil about 230 million years ago and the later theropods like the famous Tyrannosaurus rex."Various features of the skull and neck in Daemonosaurus indicate that it was intermediate between the earliest known predatory dinosaurs from South America and more advanced theropod dinosaurs," said Sues."One such feature is the presence of cavities on some of the neck vertebrae related to the structure of the respiratory system," he added.The discovery suggests that there is still much to be learned about the early evolution of dinosaurs."The continued exploration of even well-studied regions like the American Southwest will still yield remarkable new fossil finds," Sues said.
