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, May 28 (Xinhua) -- The issue of third-party online payment permits in China this week will boost the sector's development through giving it a legal status, analysts said.The People's Bank of China (PBOC), or the central bank, on Thursday announced its first batch of electronic payment licenses to 27 qualified third-party online payment platforms, including Alipay, Tenpay and 99bill.It also stipulated that all the third-party payment businesses should obtain licenses before September, or cease doing business.The move has long been awaited after the central bank said in June last year that non-financial institution payment service would be regulated, and that all businesses involved in the service must get licenses before Sept. 1, 2011.The license covers payment transactions such as Internet payment, mobile phone payment, bank card acquiring service, issuance and accept of prepaid cards and currency exchange.The move provides a legal status for the third-party payment sector so that it can develop in a more standard and healthy way, said Zhang Meng, an analyst with Analysys International, an Internet market information provider.Third-party payment enterprises refer to those non-financial operators who work as the third party between buyers and sellers to provide payment settlement through Internet, telephones or mobile phones.China has the world's highest number of Internet users, with about 457 million netizens, among whom 148 million were active online shoppers as of the end of last year.China's online payment topped 1.09 trillion yuan (167.29 billion U.S. dollars) last year. The figure was 397.3 billion yuan in the first quarter this year, almost doubled year-on-year.99bill CEO Guan Guoguang called the issue of the third-party payment licenses "a milestone" for China's e-payment sector.Requiring that enterprises must be licensed to operate e-payment businesses will help standardize the sector, improve services and boost integration of e-payment and e-commerce, said Guan.The first group of e-payment license holders include Alipay.com Co. Ltd, a unit of Alibaba Group Holding which owns the country's largest e-commerce website Alibaba.com Co. Ltd.; China UMS, a unit of China UnionPay Co. Ltd; Tenpay.com, an e-payment platform developed by Chinese Internet giant Tencent Holdings and Shengfutong, launched by Shanda Interactive Entertainment.Five applicants, however, failed to get licenses.Businesses with licenses will attract more investment and high-end personnel, says iResearch analyst Cheng Shanbao.For those without a license, they will be merged or have to pull out of the sector, according to Yeepay CEO Tang Bin.The central bank selected enterprises that have good management and risk control systems, as well as profit prospects, Zhang Meng said.Mergers are inevitable as the cut-off date of Sept. 1 is approaching, he added.The third-party payment enterprises mainly profit from 1 to 4 percent fees, but analysts believe profits from the fees might be reduced due to fierce competition.

CANBERRA, May 27 (Xinhua) -- An Australian student has discovered a part of the universe that astrophysicists have spent decades trying to find, Australia's Monash University on Friday confirmed in a statement.Astrophysicists have long thought the universe has a greater mass than is visible in the planets, but they had no way of proving it is there.Undergraduate student Amelia Fraser-McKelvie, 22, was on a summer internship at Monash University to learn more about astrophysics, when she managed to solve one of the big mysteries of science.Fraser-McKelvie, an aerospace engineering student, conducted a targeted X-ray search for the matter and found evidence of it within three months.Her tutor, Kevin Pimbblet, said the discovery is significant."We've been looking for this ordinary matter for a couple of decades," he said in a statement on Friday."It's been published in one of the most prestigious journals in the world, so astronomers all over the world will be able to read this article."Scientists had thought the matter would have a temperature of about 1 million degrees Celsius, 1.8 million degrees Fahrenheit, and should therefore be observable at X-ray wavelengths.Amelia Fraser-McKelvie's discovery has proved that prediction is correct, Pimbblet said.The trio published a research paper on the missing mass in one of the world's oldest and most prestigious scientific journals, Monthly Notices of the Royal Astronomical Society.He said the discovery could change the way telescopes are built.

BEIJING, Feb. 5 (Xinhua) -- Lending to China's small and medium-sized enterprises (SMEs) rose faster than loans to large enterprises last year, according to the People's Bank of China (PBOC), the central bank.Outstanding loans to small enterprises by banks and financial institutions jumped 29.3 percent year on year to 7.55 trillion yuan (1.15 trillion U.S. dollars) in 2010, while loans to medium-sized enterprises stood at 10.13 trillion yuan, up 17.8 percent, said the PBOC.Outstanding loans to large enterprises rose 13.3 percent to 13.42 trillion yuan, highlighting the government's efforts to optimize the loan structure, the PBOC said.About 99 percent of Chinese enterprises are SMEs which contribute 60 percent of the country's gross domestic product.Financing has long been difficult for Chinese SMEs as banks prefer to lend to big companies, particularly reputable state-owned enterprises.The government has moved to help SMEs get finance by differentiating the reserve requirement ratio for the Rural Credit Cooperative, the major lender to SMEs, and encouraging innovation in SME bond issuance.In July last year, the PBOC asked financial institutions to establish independent criteria for approving loans to SMEs and to improve efficiency in processing SME loan applications.The PBOC said SME loan growth would continue to accelerate this year.
