BERLIN, June 5 (Xinhua) -- German authority said on Sunday that bean sprouts might be the "most convincing" source for the E. coli outbreak which has killed 22 people and infected more than 2,000 in the Europe.Gert Lindemann, Agriculture Minister of the state Lower Saxony, told reporters in a press conference that restaurants and food outlets where the cases of E. coli had been reported all had received shipments of the particular bean sprouts.A related company in the Uelzen region has been shut down and its products have been recalled, he said."It is the most convincing... source for the E. coli outbreak," Lindemann said. Although a conclusive laboratory analysis will not come out until Monday, current indications were strong enough to issue a public warning, he said.Authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries - all of whom had once traveled in northern Germany. More than 600 of those infected have developed Hemolytic Uremic Syndrome (HUS), a potentially deadly complication attacking the kidneys.The source of E.coli was first thought to be the cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by Laboratory tests in Hamburg on Tuesday.

BEIJING, Aug. 18 (Xinhua) -- A controlled trial has found that Chinese herbal medicine decoction maxingshigan-yinqiaosan has a similar efficacy to oseltamivir in reducing time to fever resolution in people suffering mild H1N1 influenza virus infections.Carried out by a group of Chinese researchers, headed by Prof. Wang Chen with Beijing Chao-Yang Hospital under the Capital Medical University, the study was published by the famous internal medicine journal Ann Intern Med on Tuesday.Participants of the trial were 410 young adults aged 15 to 59 years with laboratory-confirmed H1N1 influenza.The researchers concluded that both active intervention, alone and in combination, were effective in reducing time to fever resolution in young adults with H1N1 flu, and therefore suggest that maxingshigan-yinqiaosan may be an alternative to oseltamivir.

VIENNA, Aug. 11 (Xinhua) -- Austrian researchers have developed a method of using fungi and produced enzymes to split Polyethylene Terephthalate (PET) material into their initial state, enabling the recovery of all individual components, said the Austrian Center of Industrial Biotechnology (ACIB) Thursday in a press release.Enzyme is a special protein that acts as biological catalyst, for example, bacteria and fungi in the nature can break down long chain molecules.Researchers from the Technical University of Graz, the Technical University of Vienna and the Agricultural University of Vienna jointly found that efficient enzymes are capable to break and split PET into small fragments.With different methods, the researchers forced the fungi to overproduce their precious "split-tools" after they are modified and improved by genetic engineering.Through the new method developed by the ACIB, it is now possible to decompose the PET polymer to its initial monomers with high product quality and from this to produce new high-quality materials again.This circuit avoids waste and thus saves resources and is friendly to the environment, said Geog Guebitz, head of the Research Department on Enzymes and Polymers in the ACIB.He further explained that the ACIB has established a partnership with some industrial enterprises to carry out application experiments. From the current splitting time of 24 hours, the researchers expect to shorten the whole process to "a few hours," he added.PET is a common plastic material in the polyester family, widely used in the textile industry. PET film is mainly used in electrical insulation materials, which can be also used for production of film, X-ray films and computer taps, even to produce plastic bottle and other blow molding products.

BEIJING, Aug. 23 (Xinhuanet) -- More than 90 percent of U.S. heart attack patients who need the lifesaving procedure receive it within just 90 minutes of being admitted to the hospital, according to a study released Monday in the journal Circulation.The study on the American Heart Association's journal shows that in 2010, 91 percent of heart attack patients who needed angioplasty were treated within the 90-minute window. While in 2005, 44% were.Researchers analyzed data on more than 300,000 such patients who underwent emergency angioplasty between January of 2005 and October of 2010.The improvement is the result of a nationwide effort between federal agencies, health care organizations and health care providers to improve heart attack care and outcome, said study author Dr. Harlan M. Krumholz, a professor of medicine and epidemiology and public health at Yale University School of Medicine, according to U.S. News reports.
