COPENHAGEN, May 29 (Xinhua) -- The number of confirmed E.coli cases has risen to 11 with at least another eight persons suspected of having the intestinal infection in Denmark, according to Denmark's National Serum Institute on Sunday.Five of the confirmed cases show symptoms of kidney failure which marks an advanced stage of the sickness, the institute said.Danish cucumbers are suspected of helping spread the E. coli bacteria believed to be causing a deadly outbreak of intestinal infection in Denmark and Germany, local media reported Sunday.The Danish cucumbers were mixed in Germany with cucumbers originating in the Netherlands, making it difficult to determine if Danish cucumbers are in fact contaminated.Denmark's Veterinary and Food Administration (DVFA) had earlier said the suspicion against Danish cucumber was "vague", but advised Danish consumers not to eat raw tomatoes, lettuces and cucumbers from Germany, and cucumber from Spain.It is now checking Danish cucumbers for traces of E. coli with results expected on Tuesday.Some Danish retailers have now removed these products from their supermarket shelves. And the Danish branch of fast-food chain McDonald's announced Saturday that it was dropping fresh cucumbers from its menu until further notice.The infection, which is food-borne, can be caused by eating raw or uncooked foods such as vegetables contaminated with the E. coli bacteria.Symptoms of infection include mild fever, bloody diarrhea and vomiting, and can last five to seven days. It can prove fatal in the very young, sick, or elderly.

WASHINGTON, July 5 (Xinhua) -- Intake of high levels of folate, a water-soluble B vitamin that occurs naturally in food, may reduce colorectal cancer risk, according to a new study published Tuesday in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. "We found that all forms and sources of folate were associated with lower risk of colorectal cancer," said lead author Victoria Stevens, of the American Cancer Society. "The strongest association was with total folate, which suggests that total folate intake is the best measure to define exposure to this nutrient because it encompasses all forms and sources."Total folate includes naturally occurring food folate and folic acid from fortified foods and dietary supplements.The research team investigated the association between folate intake and colorectal cancer among 99,523 participants in the Cancer Prevention Study II Nutrition Cohort; a total of 1,023 participants were diagnosed with colorectal cancer between 1999 and 2007, a period entirely after folate fortification began. Neither higher nor lower risk was observed during the first two years of follow-up (1999 to 2001), while associations were statistically significantly inverse for the subsequent years (2002 to 2007). The findings of this study add to the epidemiologic evidence that high folate intake reduces colorectal cancer incidence.Folates are essential nutrients needed to make components used for functions required for normal cell growth, including DNA synthesis and repair. Because these processes are critical for cell growth and differentiation, the relationship between folate intake and cancer development has been investigated in several cancers, and most extensively in colorectal cancer.

WASHINGTON, Aug. 18 (Xinhua) -- Black scientists were significantly less likely than their white counterparts to receive research funding from the National Institutes of Health (NIH), according to an analysis of data from 2000 to 2006.University of Kansas Professor of Economics Donna Ginther was the lead author on the study commissioned by the NIH, which will appear Friday in journal Science.The researchers found a 10 percentage point gap in research funding -- even after taking into consideration demographics, education and training, employer characteristics, NIH experience and research productivity. For example, for every 100 grants submitted to NIH, 30 grants from white applicants were funded, compared to 20 grants for black applicants.Applications for NIH funding go through peer review that considers the significance, innovation and approach of grant applications, the investigator(s) and the research environment. About half of the applications are determined to be worth scoring. Among those scored, budgets and NIH Institutes priorities determine which applications are funded. Priorities can vary by year and by Institute.The study found that applications from black researchers were less likely to be scored and on average had worse scores. After controlling for the score of the grant, there were no race or ethnicity differences in funding.Applicants self-identify race, ethnicity and gender, but that information is not available during the peer review. However, biographical facts that are included in the review materials can provide clues to the identity of the applicants.The research suggests it is possible that cumulative advantage may explain the funding differences."Small differences in access to research resources and mentoring during training or at the beginning of a career may accumulate to become large between-group differences," the paper says.Additionally, the paper suggests further research is needed to determine why black researchers are less likely to be funded.NIH Director Francis Collins and Principal Deputy Director Lawrence Tabak call the findings unacceptable and commit to immediate action by the NIH."NIH commissioned this study because we want to learn more about the challenges facing the scientific community and address them head on. The results of this study are disturbing and disheartening, and we are committed to taking action," said Collins in an accompanying commentary. "The strength of the U.S. scientific enterprise depends upon our ability to recruit and retain the brightest minds, regardless of race or ethnicity. This study shows that we still have a long way to go."NIH initiated the study in 2008 to determine if researchers of different races and ethnicities with similar research records and affiliations had similar likelihoods of being awarded a new NIH research project grant.

BEIJING, Aug. 5 (Xinhuanet) -- A study conducted by Israeli researchers at the Albert Einstein College of Medicine in New York shows that genes, rather than good eating and lifestyle habits, determine longevity, according to media reports Friday. "This study suggests that centenarians may possess additional longevity genes that help to buffer them against the harmful effects of an unhealthy lifestyle," said senior author Nir Barzilai, director of the Institute for Aging Research at Yeshiva University's Albert Einstein College of Medicine.The study involves 477 Ashkenazi Jews between the ages of 95 and 122, of whom 75 percent are women. According to the study, Ashkenazi Jews are chosen as subjects because they are more "genetically uniform than other populations, making it easier to spot gene differences that are present."The study also found that the long-lived Ashkenazi Jews drank slightly more and exercised less than their average counterparts. But Barzilai also warned: “Although this study demonstrates that centenarians can be obese, smoke and avoid exercise, those lifestyle habits are not good choices for most of us who do not have a family history of longevity.""We should watch our weight, avoid smoking and be sure to exercise, since these activities have been shown to have great health benefits for the general population, including a longer lifespan," He added.

PARIS, June 19 (Xinhua) -- Commercial Aircraft Corporation of China Ltd. (Comac) on Sunday set up its European office in Paris, the second overseas branch after its U.S. office, marking a new step for China's aviation industry in opening-up and international exchanges."The establishment of Comac Europe office is very significant. It represents the strategic cooperation between China and France and will deepen the two sides' collaboration in aerospace and all areas concerned," Chinese Ambassador Kong Quan said at an opening ceremony, citing Europe's influence in global aerospace industry and civil aviation market."Taking self-dependent innovation as the strategic cornerstone, Comac meanwhile actively conducts international cooperation and draws upon advanced technologies and experience in global civil aviation industry...," Comac President Jin Zhuanglong said.French Secretary of State for Transport Thierry Mariani (4th L), Chinese Ambassador to France Kong Quan (3rd L) and General Manager of the Commercial Aircraft Corporation of China (COMAC) Jin Zhuanglong (2nd R) attend the unveiling ceremony of COMAC Europe Office in Paris, France, June 19, 2011. The COMAC Europe Office was offically opened here Sunday.The Chinese aerospace manufacturer has built up cooperative relationship and partnership with dozens of enterprises and institutions in many countries and regions since its establishment in May 2008 in Shanghai.Regional jet ARJ21 and the trunkliner C919 are two flagship products of the young Chinese company. The group is now working to achieve certification and delivery of ARJ21-700 aircraft by the end of this year, Jin said.With regard to China's C919 trunkliner program, Jin said COMAC has signed cooperation agreements with 17 international companies in the United States and Europe, and has actively explored collaboration with GECAS, British Airways and Ryanair."In the context that the world economy is on recovery from the financial crisis, the civil aviation industry is facing great challenge. We are willing to keep close contact with all relevant public administrations and forge friendly relations and cooperation with overseas suppliers to contribute to the development of world civil aviation industry," Jin said.For the French State Secretary for Transport Thierry Marianne, who also attended the opening ceremony, the Chinese aviation market has great potential in the years to come, and China is estimated to need 3,000 new planes."We have understood that China had decided to build its own aerospace industry. It is a legitimate choice," Marianne said.A demo mock-up of the full-scale forward fuselage of C919 will be displayed during the 49th Paris Air Show on June 20-26, which will be the first time that the 1:1 demo mock-up is to be showcased at an international stage outside China, Jin told Xinhua.During the air show, Comac is going to sign agreements with an international airline and an airborne-system supplier and carry out a series of activities concerning international cooperation and exchanges, according to the group.
