CANBERRA, Oct. 15 (Xinhua) -- Prisoners and health experts on Saturday told national broadcasting network ABC News that they are concerned of a looming HIV epidemic in Australia's prisons.The warning came following a test report undertaken in August showed that 40 percent of inmates at a correctional center in Canberra of Australia tested positive to Hepatitis C.According to the head of the Alcohol and Drug Service based at St Vincent's Hospital in Sydney, Alex Wodak, roughly 25 percent of Australia's prison population are injecting drugs, and he is concerned about the risk of an HIV explosion in Australia originating in prisons."Were Australia to have an epidemic of HIV beginning among people who inject drugs, it is almost certain that it would begin in one of our prisons. So we are very exposed to this risk," he told ABC News on Saturday.The Australia Capital Territory state government has proposed a trial prison needle exchange program in Canberra's correctional center, and Paul Cubitt, who currently works at the Alexander Maconochie Center in Canberra, said he has never seen so many syringes in a jail."Under a controlled regime it will actually take those needles that currently exist within a correctional center out of the environment, and prisoners will be more willing to use a clean item under a level of anonymity which then protects them and protects staff," he said.Meanwhile, The Community and Public Sector Union 's national secretary, Nadine Flood, agrees action must be taken to curb prisoner drug use.Dr Wodak noted that prison needle exchange programs have been operating overseas for over a decade with ten countries provide inmates with clean needles, and said it is shameful Australian prisons are lagging behind.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

BEIJING, Oct. 11 (Xinhuanet) -- An experimental drug that can remove amyloid plaques from the brains of Alzheimer's patients is being developed by Swiss Roche Holding AG in a small early-stage study, according to a report published in the Archives of Neurology on Monday.Researchers suspect the build-up of such plaques may be a cause of the memory robbing disease, although that theory has yet to be definitively proved. Gantenerumab, a biotech drug designed to bind to amyloid plaques in the brain and remove them, is being targeted at the early stages of Alzheimer's with the hope it can slow progression of the disease while patients are still able to function.The Phase I study of 16 Alzheimer's patients tested gantenerumab at two doses against a placebo over six months of treatment.The Roche drug led to a dose-dependent reduction of brain amyloid, while amyloid load increased in patients receiving a placebo, the report said.The next step will be to investigate whether removal of brain amyloid translates into clinical benefit for patients at doses of the experimental drug that are well tolerated and safe, the report said.Much larger trials and further study will be needed to fully understand how gantenerumab works and whether it can stave off Alzheimer's, said the report.Roche is approaching the disease far earlier because amyloid accumulates for 15 years before dementi.

WASHINGTON, Nov. 14 (Xinhua) -- A novel study in twins found that exposure to trichloroethylene (TCE) -- a hazardous organic contaminant found in soil, groundwater, and air -- is significantly associated with increased risk of Parkinson's disease (PD). Possibility of developing this neurodegenerative disease is also linked to perchloroethylene (PERC) and carbon tetrachloride (CCI4) exposure, according to the study appearing in Annals of Neurology on Monday.The National Institute of Neurological Disorders and Stroke estimates that as many as 500,000 Americans have PD and more than 50,000 new cases are diagnosed annually. While there is much debate regarding cause of PD, studies suggest that genetic and environmental factors likely trigger the disease. Several studies have reported that exposure to solvents may increase risk of PD, but research assessing specific agents is limited.The current epidemiological study, led by Samuel Goldman and Caroline Tanner with The Parkinson's Institute in Sunnyvale, California, investigated exposure to TCE, PERC and CCI4 and risk of developing PD. The team interviewed 99 twin pairs in which one twin had PD and one didn't, inquiring about lifetime occupations and hobbies. Lifetime exposures to six specific solvents previously linked to PD in medical literature -- n-hexane, xylene, toluene, CCI4, TCE and PERC -- were inferred for each job or hobby.The findings are the first to report a significant association between TCE exposure and PD -- a more than six-fold increased risk. Researchers also found that exposure to PERC and CCI4 tended toward significant risk of developing the disease. "Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Goldman in a statement.TCE, PERC and CCI4 have been used extensively worldwide, with TCE noted as a common agent in dry-cleaning solutions, adhesives, paints, and carpet cleaners. Despite the U.S. Food and Drug Administration (FDA) banning the use of TCE as a general anesthetic, skin disinfectant, and coffee decaffeinating agent in 1977, it is still widely used today as a degreasing agent. In the U.S., millions of pounds of TCE are still released into the environment each year and it is the most common organic contaminant found in ground water, detected in up to 30 percent of drinking water supplies in the country.In a release issued on Sept. 28, 2011, the Environmental Protection Agency announced that TCE is carcinogenic to humans.

ZHENGZHOU, Oct. 21 (Xinhua) -- A leading Chinese producer for quick-frozen snacks Thursday apologized for the production and sale of bacteria-contaminated dumplings and said that a recall was underway.A spokeswoman from Zhengzhou Sinian Food Co., Ltd. said they had confirmed the contamination of staphylococcus aureus, or golden staph, in its quick-frozen seafood and pork-stuffed dumplings.The company had started the recall and destruction of the contaminated products, said Lin Xiaohong, a marketing executive of the company, adding that an investigation into the source of the contamination was underway.The statement came after authorities in Beijing announced they had detected golden staph from one batch of dumpling products by the Henan-based company. The bacteria can cause various diseases, including pneumonia and sepsis, and is strictly banned in food procession.
