WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.

UNITED NATIONS, Nov. 1 (Xinhua) -- China on Tuesday urged the International Atomic Energy Agency (IAEA) to further strengthen its leading role in enhancing global nuclear safety and promoting relevant international cooperation.Wang Min, Chinese deputy representative to the United Nations, made the remarks at an open meeting of the 66th session of UN General Assembly on the IAEA report.IAEA shoulders important responsibilities in promoting peaceful uses of nuclear energy and preventing nuclear proliferation, Wang said, adding that it needs to further summarize experiences and lessons of the Fukushima nuclear accident, assisting member states to enhance nuclear safety and emergency response capabilities.Wang urged the IAEA to "increase technical assistance to developing countries, improve newcomer's national nuclear infrastructure and promote the safe, secure and sustainable development of nuclear energy."The IAEA was also asked to strengthen nuclear safeguards regime, effectively prevent nuclear proliferation, and maintain an objective and impartial stand on sensitive and hot nuclear issues.China has always adhered to the principle of "safety first", he said. "China has established a rather comprehensive legal and standards system on nuclear safety, put in place an independent and effective supervision and regulatory framework, set up a comprehensive emergency response mechanism, and keep a good safety record in general."China has decided to contribute 200,000 U.S. dollars to the Nuclear Security Fund of the IAEA for the purpose of enhancing nuclear security capability of the Asia-Pacific Region, Wang added.

BEIJING, Jan. 19 (Xinhua) -- China's major textile companies are expected to witness an annual increase of 8 percent in their value-added output over the next four years, the Ministry of Industry and Information Technology said Thursday.The ministry published a plan regarding supporting the development of the textile industry during the country's 12th Five-Year Plan period (2011-2015), according to which the sector's exports will reach 300 billion U.S. dollars by 2015 with an annual growth of 7.5 percent.The industry is also expected to employ 20 million people by 2015 and its energy consumption per unit of value-added output will drop by 20 percent from 2010, the guideline said.The country will encourage the textile industry to enhance brand-building and aims to build 5-10 textile companies of global influence and 50 companies with an annual revenue of more than 10 billion yuan by 2015.The guideline warned of potential risks for the sector, including volatile changes in raw material prices, rising production costs and a complicated international trade environment.The guideline said the industry should develop new products and explore new markets to ensure a healthy development during the coming period.

BEIJING, Oct. 24 (Xinhuanet) -- There is no evidence to prove that using a cell phone can increase the risks of brain cancer, suggested a lastest study by Danish researchers.To arrive at the result, the researchers examined the health records from 1990 to 2007 for 358,403 Danish cell phone plan subscribers.They found that among people using cell phones for as long as 13 years or more, the cancer risks were almost the same as for non-subscribers.The finding, published in the British Medical Journal last week, alleviated the fear among the world's 5 billion cell phone users.Five months ago, a statement from the World Health Organization's International Agency for Research on Cancer (IARC) sparked fear in cell phone users around the world because it said that cell phone use might cause brain cancer.However, the finding could not rule out the risk of brain cancer triggered by heavy use of cell phones, admitted Patrizia Frei of the Danish Cancer Society's Institute of Cancer Epidemiology, lead author of the study.Frei added, cited by CNN, "There are still some open questions, about greater amounts of use, and about the effects on children."The IARC did not give formal response to the study, but it offered some ways for cell phone consumers to reduce possible risks months ago.Texting and using hands-free sets for voice calls lower exposure to potentially harmful radiation, compared to device-to-ear voice calls, by at least 10-fold, IARC stated, reported by the New York Daily News.

WASHINGTON, Dec. 5 (Xinhua) -- A recent study found that low vitamin D levels are significantly more prevalent in obese children and are associated with risk factors for type 2 diabetes. This study was accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism.High rates of vitamin D deficiency have been found in obese populations and past studies have linked low vitamin D levels to cardiovascular disease and type 2 diabetes. But the mechanisms by which obesity and its comorbidities are related to vitamin D deficiency are not fully known.This new study examined associations between vitamin D levels and dietary habits in obese children, and tested whether there were correlations between vitamin D levels and markers of abnormal glucose metabolism and blood pressure.In this study, researchers measured vitamin D levels, blood sugar levels, serum insulin, body mass index (BMI) and blood pressure in 411 obese subjects and 87 control non-overweight subjects. Study participants were also asked to provide dietary information including daily intake of soda, juice and milk, average daily fruit and vegetable intake, and whether or not they routinely skipped breakfast. BMI is a measurement of body fat calculated from weight and height."Our study found that obese children with lower vitamin D levels had higher degrees of insulin resistance," said Micah Olson, of The University of Texas Southwestern Medical Center in Dallas and lead author of the study. "Although our study cannot prove causation, it does suggest that low vitamin D levels may play a role in the development of type 2 diabetes.""Poor dietary habits such as skipping breakfast and increased soda and juice intake were associated with the lower vitamin D levels seen in obese children," said Olson. "Future studies are needed to determine the clinical significance of lower vitamin D levels in obese children ... and whether treatment with vitamin D can improve primary clinical endpoints such as insulin resistance.
