BEIJING, Sept. 4 (Xinhua) -- Officials and delegations from China and African countries have gathered at a seminar being held in Beijing to discuss rural development and economic growth.The seven-day seminar kicked off on Sunday, attracting representatives from China and 11 African countries to exchange views and experiences related to the seminar's theme of "agriculture and rural development."Justin Lin Yifu, chief economist and senior vice president of the World Bank, said at the seminar's opening ceremony that African countries should take cues from China's experience in creating a series of policies to bolster agricultural and rural development, as these policies have also facilitated the country's economic growth.Hu Jinglin, assistant to China's Minister of Finance, said improved agricultural cooperation between China and Africa will help enhance global grain security.China has worked on 142 cooperative agricultural projects with 14 African countries to date. In addition, it has sent 104 agricultural experts to 33 African countries to train more than 4,200 local agricultural technicians.

BEIJING, July 26 (Xinhuanet) -- Some forms of medical research involving animals containing human material should be more tightly regulated, a report warned.The warning was issued on Friday by an expert working group from the Academy of Medical Sciences in Britain.The report suggested the ban of the use of animal cells that can produce human sperm or egg cells. "We don't want scientists to cause problems for the future by overstepping the mark of what is publicly acceptable," said Professor Robin Lovell-Badge, a member of the expert working group.The controversy partly originated from a medical research in Britain. Three years ago, the researchers produced human embryos with the nucleus hollowed cow eggs, according to the Associated Press."This is a complex research area and there should be an ongoing dialogue between scientists, regulators and the wider public to address emerging issues." said Martin Bobrow, a professor of medical genetics at the University of Cambridge.

WASHINGTON, July 5 (Xinhua) -- Adhering to a healthy lifestyle, including not smoking, exercising regularly, having a low body weight and eating a healthy diet, appears to lower the risk of sudden cardiac death (SCD) in women, according to a study to be published Wednesday in the Journal of the American Medical Association."Sudden cardiac death (defined as death occurring within one hour after symptom onset without evidence of circulatory collapse) accounts for more than half of all cardiac deaths, with an incidence of approximately 250,000 to 310,000 cases annually in the United States," the authors write as background information in the study.Using data collected as part of the Nurses' Health Study, Stephanie Chiuve, of Brigham and Women's Hospital and Harvard Medical School, and colleagues examined the association between a healthy lifestyle and risk of SCD.A total of 81,722 women who participated in the Nurses' Health Study from June 1984 to June 2010 were included in the new study, and lifestyle factors were assessed via questionnaires every two to four years. A low-risk lifestyle was defined as not smoking, having a body mass index (BMI) of less than 25, exercise duration of 30 minutes/day or longer, and consuming a diet closely related to a Mediterranean-style diet (emphasizes high intake of vegetables, fruits, nuts, legumes, whole grains and fish, with moderate alcohol intake).During the 26 years of follow-up, there were 321 cases of SCD among women (average age 72 years at the time of the SCD event) in the study. All four low-risk factors were significantly and independently associated with a lower risk of SCD. Not smoking, exercising and eating a healthy diet each were inversely associated with risk of SCD. BMI also was associated with the risk of SCD, with women having a BMI between 21 and 24.9 at lowest risk.Women at low risk for all four lifestyle factors had a 92 percent lower risk of SCD when compared with women at low risk for none of the four lifestyle factors."In this cohort of female nurses, adherence to an overall healthy lifestyle was associated with a lower risk of SCD and may be an effective strategy for the prevention of SCD," the authors write.

BEIJING, Aug. 15 (Xinhua) -- Scientists in a lab with Daya Bay Nuclear Power Station in southern Guangdong Province have found neutrino through two detecting instruments, which is likely to provide clues to solving the mystery of why there is more matter than antimatter in the universe.The Institute of High Energy Physics with the Chinese Academy of Sciences on Monday announced the breakthrough that was achieved by more than 250 researchers from six countries and regions.The two neutrino detectors are installed underground 360 meters away from the nuclear plant at a depth of 100 meters.Scientists believe that matter and antimatter were created in equal amounts during the Big Bang, but the disappearance of antimatter remains a mystery.Neutrino is an elementary particle that is able to pass through ordinary matter almost unaffected, which makes it extremely difficult to detect.Located in Shenzhen, a city neighboring Hong Kong, the Daya Bay Nuclear Power Station commenced operation in 1993.Scientists from the Chinese Academy of Sciences and the U.S.-based Brookhaven National Laboratory and the Lawrence Berkeley National Laboratory started the underground neutrino experiment in 2006.Kam-Biu Luk, spokesman for the laboratory, said that the results of the experiment would further shed light on the evolution of basic matter after the Big Bang.The neutrino experiment in the Daya Bay is one of the largest cooperation projects with regards to basic research between China and the United States.Among the participants of the experiment are Russia, Czech Republic, and China's Hong Kong and Taiwan regions.

WASHINGTON, June 7 (Xinhua) -- Salmonella infections have not decreased during the past 15 years and have instead increased by 10 percent in recent years in the United States, according to a report released Tuesday by the Centers for Disease Control and Prevention (CDC).During the same time period, illnesses from the serious Shiga toxin-producing E. coli O157 have been cut nearly in half and the overall rates of foodborne infections have been reduced by 23 percent, the new Vital Signs report said.The report summarizes 2010 data from CDC's Foodborne Diseases Active Surveillance Network (FoodNet), which serves as America's report card for food safety by tracking whether nine of the most common infections transmitted through foods are increasing or decreasing."Although foodborne infections have decreased by nearly one-fourth in the past 15 years, more than one million people in this country become ill from Salmonella each year, and Salmonella accounts for about half of the hospitalizations and deaths among the nine foodborne illnesses CDC tracks through FoodNet," said CDC Director Thomas Frieden in a statement.In 2010, FoodNet sites, which include about 15 percent of the American population, reported nearly 20,000 illnesses, 4,200 hospitalizations and 68 deaths from nine foodborne infections. Of those, Salmonella caused more than 8,200 infections, nearly 2,300 hospitalizations and 29 deaths (54 percent of the total hospitalizations and 43 percent of the total deaths reported through FoodNet). CDC estimates that there are 29 infections for every lab-confirmed Salmonella infection.Salmonella, which is responsible for an estimated 365 million U.S. dollars in direct medical costs each year in the United States, can be challenging to address because so many different foods like meats, eggs, produce, and even processed foods, can become contaminated with it and finding the source can be challenging because it can be introduced in many different ways.In response to that challenge, the U.S. Food and Drug Administration, which regulates eggs, produce and many processed foods, has developed new rules for the egg industry to follow under its recently expanded regulatory authorities.The rate of E. coli O157 cases reported by FoodNet was two cases per 100,000 people in 1997 and, by 2010, had decreased to 0.9 cases per 100,000 people. The CDC credits the reduction in E. coli to improved detection and investigation of outbreaks, cleaner slaughter methods, better inspections of ground beef processing plants, and increased awareness by consumers and restaurant employees of the importance of properly cooking beef.
