SYDNEY, May 27 (Xinhua) -- A toddler and a policeman have become the latest victims of a rare and potentially deadly mosquito-borne disease in Western Australia (WA), local media reported on Friday.The two-year-old child contracted Murray Valley encephalitis (MVE) in the Kimberley of WA and is now in Royal Darwin Hospital in a stable condition, according to Australian Associated Press (AAP).The 29-year-old police officer, who was recently contracted the disease at an Aboriginal community of WA, has emerged from a coma in a Perth hospital but is still unable to communicate.It is not known if the victims from WA's far north will fully recover.In April 2011, a man who had been traveling in WA's northwest became the first person in the state to die from the disease in three years.A 19-year-old Canadian tourist also died after contracting MVE while traveling through the Northern Territory earlier in May.A WA Health Department spokeswoman said nine West Australians had contracted MVE so far in 2011. Several people remain very ill in hospital, she said.

WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."

BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.

WASHINGTON, March 22 (Xinhua) -- A long-term study by Greek researchers has shown the effectiveness of replacing bone marrow, purposely destroyed by chemotherapy, with autologous (self) stem cells in treating people with aggressive forms of multiple sclerosis (MS).The study was published on Tuesday in Neurology, the medical journal of the American Academy of Neurology.For the treatment, chemotherapy drugs are used to kill all of the patient's blood cells, including the immune cells that are believed to be attacking the body's own central nervous system. Bone marrow stem cells removed from the patient are purified and transplanted back into the body, which saves life by replacing the blood cells and also is proposed to "reboot" the immune system.A human embryonic stem cell line derived at Stanford University is seen in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009The study followed 35 people for an average of 11 years after transplant. The study involved people with rapidly progressive MS who had tried a number of other treatments for MS with little or no effect. All were severely disabled by the disease, with an average score of six on a scale of disease activity that ranges from zero being a normal neurological examination to 10 meaning death due to MS.A score of six means able to walk with a cane or crutch; a seven is mainly in a wheelchair. All had worsened by at least one point on the scale in the year prior to the transplant.After the transplants, the probability of participants having no worsening of their disease for 15 years was 25 percent. The probability was higher -- 44 percent -- for those who had active brain lesions, which are a sign of disease activity, at the time of the transplant.For 16 people, symptoms improved by an average of one point on the scale after the transplant, and the improvements lasted for an average of two years. The participants also had a reduction in the number and size of lesions in their brains. Two people (six percent) died from complications related to the transplant at two months and 2-1/2 years post-transplant.Study author Vasilios Kimiskidis, of Aristotle University in Thessaloniki, Greece, noted that more research is needed on this treatment, including studies that compare people receiving the treatment to a control group that does not receive the treatment."Keeping that in mind, our feeling is that stem cell transplants may benefit people with rapidly progressive MS," he said. "This is not a therapy for the general population of people with MS but should be reserved for aggressive cases that are still in the inflammatory phase of the disease."

WASHINGTON, April 25 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) and the U.S. Agency for International Development (USAID) have agreed to expand their joint efforts to overcome international development challenges such as food security, climate change, and energy and environmental management.NASA Administrator Charles Bolden and USAID Administrator Rajiv Shah signed a five-year memorandum of understanding on Monday, at NASA Headquarters. The agreement formalizes ongoing agency collaborations that use Earth science data to address developmental challenges, and to assist in disaster mitigation and humanitarian responses. The agreement also encourages NASA and USAID to apply geospatial technologies to solve development challenges affecting the United States and developing countries."Technologies for NASA missions have long improved life here on Earth. Together with USAID, we'll meet even more sustainable development challenges here on the ground, solving problems for the world community," Bolden said in a statement. "As we explore space, we'll also be exploring solutions to important health, nutritional and safety challenges in developing countries."The agencies will continue collaborations to stimulate innovative science and technology solutions to international development challenges by using Earth science data, research results, computer models, visualization applications and remote- sensing techniques.USAID is the lead federal development agency implementing U.S. development efforts through field-based programs and projects around the world. NASA has broad experience with Earth science research, development of Earth science information products, and technology applications."Through our partnership with NASA, we can apply the latest, cutting-edge technology to deliver meaningful results for people in developing countries in areas like health, food security and water," Shah said. "It's a prime example of our efforts to use the power of science and technology to tackle today's pressing development challenges."Since 2003, NASA and USAID have worked together building and expanding the SERVIR program, which allows people in developing regions to use Earth observations for addressing challenges in agriculture, biodiversity conservation, climate change, disaster response, weather forecasting, and energy and health issues.The agencies also collaborate on the LAUNCH program, which supports science and technology innovators in the nonprofit and private sectors. The program's goal is improving innovations to achieve greater impact on sustainability issues.
