BERLIN, June 14 (Xinhua) -- A two-year-old boy became the first child to be killed by the deadly E. coli in Germany on Tuesday, officials said.To date, the terrifying EHEC infection has claimed 36 lives in Germany and one in Sweden.The child, from the northern town of Celle, died in hospital in Hanover of kidney failure and abnormal breakdown of red blood cells, two extreme symptoms of the infection with enterohaemorrhagic E. coli (EHEC), authorities in the state of Lower Saxony said.The boy became the youngest known fatal victim since the outbreak of E. coli in May. His father and 10-year-old brother were also infected with the deadly bacteria, but are recovering, doctors told a local newspaper.The Robert Koch Institute, Germany's national disease prevention and control agency, said on Tuesday that a total of 3, 235 cases had been reported in the country. Among them, 782 people are suffering from haemolytic uraemic syndrome (HUS), a life- threatening illness arising from E. coli, which would destroy human kidney and nervous system.The institute added that the number of new infections is declining sharply in recent days, with only seven reported on Tuesday.German authorities announced on Friday that bean sprouts from a farm in northern Germany were one source of the outbreak, and dropped the previous warning against eating raw cucumbers, tomatoes and lettuce. However, the food panic has caused losses worth hundreds of millions of dollars for European farmers.

YUEYANG, Hunan, June 2 (Xinhua) -- The population of finless porpoises, an endangered species of freshwater dolphin that lives in China's Yangtze River, may decrease by over 80 percent over the next 30 years, experts said on Thursday after conducting a field survey along the river.The rare species will edge closer to extinction if no action is taken, said Wang Ding, a dolphin expert from the Hydrobiology Institute of the Chinese Academy of Sciences.Wang's team conducted a survey on Poyang Lake, Dongting Lake and other locations along the Yangtze from Sunday to Wednesday this week.The dolphin population currently stands at 1,000, even lower than that of the giant panda, Wang said.The dolphin population is decreasing by a rate of 6.4 percent annually, Wang said."The next ten years will be a critical period for the conservation of this species," Wang said.A long-lasting drought in central China has lowered water levels in many of the region's lakes and rivers, doing great harm to the dolphins' habitat and leading to a decrease in population, Wang said.Mei Zhigang, a member of Wang's survey team, said that human activity has also contributed to the dropping population.Mei said that large numbers of shipping vessels on the Yangtze have impeded the dolphins' migration path, causing them to reproduce less frequently.

BEIJING, Sept. 26 (Xinhuanet) -- Although it is home to traditional Chinese medicine (TCM), China must do much more to improve its academic research capacity for acupuncture, a form of TCM, to take the lead worldwide on both the academic and clinical sides.At present, among all academic theses on acupuncture indexed by the Science Citation Index (SCI), a leading world thesis index system, only 5 percent are from the Chinese mainland, according to Wang Linpeng, the director of the acupuncture and moxibustion center of the Beijing Hospital of Traditional Chinese Medicine, which is affiliated with the Capital Medical University.Although Chinese acupuncturists absolutely excel worldwide in clinical practice, "they are not as good as their foreign peers in academic capacity, particularly Western-style research methods and lab experiment design," he told China Daily on Friday during the 2011 International Symposium on Acupuncture. A patient suffering from facial paralysis receives acupuncture treatment at a hospital in Nanjing, the capital of Jiangsu province, on Dec 6, 2010.Studies by TCM practitioners - including acupuncturists - largely focus on their area of specialization, and few are in line with global interest in the medical science that has been proven effective over thousands of years, he said."Chinese TCM practitioners are very good at treating conditions, but they are clumsy at showing how and why it really works in an internationally accepted 'language' and 'manner'," said Gao Sihua, chancellor of the Beijing University of Chinese Medicine."It's especially true in TCM circles, where few Chinese practitioners would regularly follow international academic articles and research trends," Wang said.Measured by the number of articles on acupuncture indexed by SCI, the US and European countries lead globally, he said.

CANBERRA, Sept. 9 (Xinhua) -- Managing other people at work triggers structural changes in the brain, protecting its memory and learning center well into old age, Australia's study revealed on Friday.Australia's University of New South Wales (UNSW) researchers have, for the first time, identified a clear link between managerial experience throughout a person's working life, and the integrity and larger size of an individual's hippocampus (the area of the brain responsible for learning and memory) at the age of 80. "We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus," Dr Michael Valenzuela, Leader of Regenerative Neuroscience in UNSW's School of Psychiatry, said in a statement released on Friday."This could be linked to the unique mental demands of managing people, which requires continuous problem solving, short term memory and a lot of emotional intelligence, such as the ability to put yourself in another person's shoes. Over time this could translate into the structural brain changes we observed."The findings confirmed that staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer's.Using MRI imagery in a cohort of 75-92 year-olds, researchers found larger hippocampal volumes in those with managerial experience compared to those without. The effect was also seen in women who had taken on managerial roles in nursing or teaching, for example.The study was presented at this week's Brain Sciences UNSW symposium Brain Plasticity The Adaptable Brain, held in Australia.

BEIJING, June 14 (Xinhuanet) -- Having a pet at home during the first year of a child may halve the risk of developing allergic to them later in life, a new study suggests.The study was published in the journal Clinical & Experimental Allergy.Researchers from Henry Ford Hospital in Detroit assessed 566 boys and girls who were followed from birth until age 18. They found that boys who had dogs and teens who had cats during their first year of life had 50 percent less risk of developing pet allergies later.Lead researcher Ganesha Wegienka said: "This research provides further evidence that experiences in the first year of life are associated with health status later in life, and that early life pet exposure does not put most children at risk of being sensitised to these animals later in life."The researchers said that exposure to animals at other times in childhood didn't appear to be as significant as the first year.However, Wegienka cautioned that this study doesn't prove a cause-and-effect relationship between having a pet and avoiding allergies, just an association between those two factors."We don't want to say that everyone should go out and get a dog or cat to prevent allergies," she said."More research is needed, though we think this is a worthwhile avenue to pursue."
