SYDNEY, Sept. 5 (Xinhua) -- Australian scientists believe " brown fat," a wondrous tissue that burns energy to generate heat, could help people fight obesity, local media reported on Monday.A research team from Sydney's Garvan Institute of Medical Research (GIMR) has worked out how to grow brown fat from stem cells biopsied from adults, raising hopes that one day brown fat could be transplanted in obese people to speed up calories they burn, the Australian Associated Press (AAP) reported.Garvan endocrinologist Paul Lee, who led the research, is optimistic about targeting brown fat as an obesity intervention, commenting "it's a highly metabolically active form of fat, and very exciting that we may be able to stimulate its growth in people."People are born with supplies of brown fat around their neckline to keep them warm as infants, according to scientists at GIMR.Scientists now know that brown fat is present in most, if not all, adults mainly just behind the collarbone.Studies have found that adults with brown fat are slimmer than those without."Although this is early work, it is a proof of concept study showing that the growth of brown fat cells is possible, using precursor cells taken from adult humans, under appropriate stimulation," Lee said."Regardless of whether or not someone has lots of or little brown fat, the precursor cells are universally present. Under the appropriate growth factor and hormonal stimulation, the cells all grow and differentiate into mature brown fat cells."However, Lee warned more work was needed.Lee said even if brown fat was transplanted into obese people or drugs developed to stimulate the growth of brown fat, exercise and a healthy diet would still be crucial to aiding weight loss."So I don't think this is a solution to obesity because there are so many other factors (involved in obesity)," he said."Despite how efficient brown fat is at burning energy, we would only need a few doughnuts to diminish or negate its benefits."Lee said it would be years before tests could be carried out on brown fat transplants.In the meantime, he is expanding his study to test different ways to grow brown fat.His study, to be printed in the October issue of Endocrinology, has been published in the online edition of the journal.

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.

SHENYANG, Aug. 16 (Xinhua) -- Two more cutaneous anthrax infections were reported in northeast Liaoning Province, bringing the total number of people who were hospitalized for the disease to 32, health authorities said Tuesday.The two cases were found Monday in Donggang City, more than 100 km away from the city where the disease was first reported, the Liaoning Provincial Health Department said in a statement.Health experts noted that all the cases originated from the the same source.As of 8 p.m. Monday, four cases have been confirmed while 28 others were still being investigated, according to the health department.An initial investigation by local health authorities showed that the patients contracted the disease after direct contact with diseased cattle.The government of Liaoning has since killed or disinfected more than 400 heads of cattle in the province and carried out a survey among over 20,000 people.Cutaneous anthrax is an infection of the skin caused by direct contact with infected animals or animal products. It is rarely fatal if treated.

VIENNA, Sept. 9 (Xinhua) -- The three-day Traditional Chinese Medicine (TCM) exhibition opened Friday in the Flower Garden Hirschstetten in Vienna, with the aim to introduce traditional Chinese medicine to the Austrians and to arouse their interest in the culture of Chinese medicine.Holding for the second time, the exhibition this year have attracted more visitors to take part in the health talks on traditional Chinese medicine, read or buy books around the theme of traditional Chinese medicine. Some visitors enthusiastically tried Chinese diet therapy prepared by the organizers.In recent years, traditional Chinese medicine has been increasingly recognized and accepted in Austria. It has already not only entered into the classroom but also into the hospital and clinic.Some private health insurance companies in Austria have started to include the treatment by traditional Chinese medicine into their insuring categories. Chinese patent drugs are already available in many pharmacies in Austria.But in general, traditional Chinese medicine still faces many limits in Austria, which hasn't been involved into the public health insurance system. Some Austrians still have doubts of Chinese medicine, in particular the medicinal herb drugs. All these have restricted the development of traditional Chinese medicine here.Currently, major clinics of traditional Chinese medicine carry out only acupuncture and moxibustion, massage and other health-care physical therapy.Richard Schmerker, a doctor of traditional Chinese medicine in Austria, told reporters that the development of traditional Chinese medicine here still faces many challenges and the biggest one is the shortage of effective propaganda and popularization.But he expressed his full confidence about the future of traditional Chinese medicine in Austria. He said, the uniqueness of finding the root cause of diseases and laying the axe to the root will make it be accepted by more and more Austrians.
