LOS ANGELES, June 4 (Xinhua) -- Pregnant women who eat high-fat diet may be more likely to have a higher rate of stillbirth, a new study suggests.Researchers at Oregon Health & Science University (OHSH) came to the conclusion after observing 24 pregnant Japanese macaques that ate either a diet comprising 32 percent calories from fat or a control diet with 14 percent fat calories for at least four years.The researchers found the monkeys that ate a high-fat diet experienced a significant decrease in blood flow from the uterus to the placenta, a reduction of 38 percent to 56 percent, and a rise in placental inflammation.This was the case regardless of whether the monkeys were obese or slender. The risk of stillbirth was further compounded, however, when the monkeys were obese with hyper-insulinemia, or pre-diabetes.A large order of McDonald's french fries are shown May 22, 2008. McDonald's has switched to cooking oils free of trans fats in all of its restaurants in the United States and Canada, Chief Executive Jim Skinner said on may 23Eating a high-fat diet decreases blood flow from the mother to the placenta, the temporary organ that nourishes the unborn fetus, thus raising the risk of stillbirth, the researchers explained.Because the placental structure of the Japanese macaque is very similar to that in humans, cause and effect can be better established, the researchers said.Additional studies are needed to determine exactly how a high- fat diet decreases placental blood flow, the researchers noted.This is the first study to explain exactly how a fatty diet contributes to stillbirth, the researchers said in the study appearing in the June edition of the journal Endocrinology.The researchers hope their work will inform expectant moms and their physicians about the inherent dangers of a high-calorie, high- fat diet."This study demonstrates that maternal diet during pregnancy has a profound influence on both placental and fetal development," said Antonio Frias, M.D., principal investigator and assistant professor of obstetrics and gynecology (perinatology/maternal-fetal medicine) in the OHSU School of Medicine."The high-calorie, high-fat diet common in our society has negative effects on placental function and may be a significant contributor to adverse pregnancy outcomes, such as stillbirth."Previous studies have shown that nearly all adverse outcomes during pregnancy -- abnormal fetal growth, preeclampsia, preterm labor and stillbirth -- are in some way associated with an abnormally developed, or damaged, placenta, the temporary organ that nourishes the unborn fetus.In addition, maternal obesity has been associated with placental inflammation and dysfunction and an increased risk of stillbirth.Taking these findings into account, the researchers hypothesized that eating a diet high in fat during pregnancy also may increase the risk of placental inflammation and the risk of stillbirth.The researchers said they plan to conduct further studies on the impact of dietary changes and diet supplementation on improving outcomes in both monkeys and humans.

LOS ANGELES, June 10 (Xinhua) -- The Aquarius/SAC-D observatory, NASA's first ever satellite to study the saltiness of Earth's oceans, is in excellent health after its launch early Friday, initial telemetry reports showed.The observatory rocketed into space from Vandenberg Air Force Base in California atop a United Launch Alliance Delta II rocket at 7:20:13 a.m. PDT (10:20:13 a.m. EDT).Less than 57 minutes later, the observatory separated from the rocket's second stage and began activation procedures, establishing communications with ground controllers and unfurling its solar arrays, NASA's Jet Propulsion Laboratory (JPL) said.During the next 25 days, the Aquarius/SAC-D service platform will be tested and maneuvered into its final operational, near-polar orbit 408 miles (657 kilometers) above Earth. Science operations will begin after the observatory's instruments are checked out. This commissioning phase may last up to 65 days, JPL said.Aquarius will map the global open ocean once every seven days for at least three years with a resolution of 93 miles (150 kilometers). The maps will show how ocean surface salinity changes each month, season and year. Scientists expect to release preliminary salinity maps later this year."Aquarius is a critical component of our Earth sciences work, and part of the next generation of space-based instruments that will take our knowledge of our home planet to new heights," said NASA Deputy Administrator Lori Garver. "The innovative scientists and engineers who contributed to this mission are part of the talented team that will help America win the future and make a positive impact across the globe."Aquarius will measure salinity by sensing thermal microwave emissions from the water's surface with three microwave instruments called radiometers. When other environmental factors are equal, these emissions indicate the saltiness of surface water. A microwave radar scatterometer instrument will measure ocean waves that affect the precision of the salinity measurement.Because salinity levels in the open ocean vary by only about five parts per thousand, Aquarius will be able to detect changes as small as approximately two parts per 10,000, equivalent to about one-eighth of a teaspoon of salt in a gallon of water."Data from this mission will advance our understanding of the ocean and prediction of the global water cycle," said Michael Freilich, director of NASA's Earth Science Division in the Science Mission Directorate at agency headquarters in Washington. "This mission demonstrates the power of international collaboration and accurate spaceborne measurements for science and societal benefit. This would not be possible without the sustained cooperation of NASA, CONAE and our other partners."The Aquarius/SAC-D (Satellite de Aplicaciones Cientificas) observatory is a collaboration between NASA and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE).Aquarius was built by NASA's JPL and the Goddard Space Flight Center in Greenbelt, Maryland. NASA's Launch Services Program at the Kennedy Space Center in Florida manages the launch.JPL will manage Aquarius through its commissioning phase and archive mission data. Goddard will manage Aquarius mission operations and process science data. CONAE is providing the SAC-D spacecraft, optical camera, thermal camera with Canada, microwave radiometer, sensors from various Argentine institutions and the mission operations center. France and Italy also are contributing instruments.

SYDNEY, Aug. 25 (Xinhua) -- Scientists in Australia have discovered a way of stopping mosquitoes carrying dengue virus, raising hopes for preventing the 50 million human cases of the disease every year, local media reported on Thursday.Groundbreaking experiments in Queensland have found a common insect bacteria, wMel Wolbachia, which can dramatically reduce the presence of dengue fever in mosquitoes.The research, led by Professor Scott O'Neill, Dean at Melbourne's Monash University, was published on Thursday in the prestigious journal, Nature.Australian researchers working on the Eliminate Dengue program aim to protect the mosquitoes themselves from dengue and so stop them transmitting the virus to humans."What the experiments have shown is that this strain of Wolbachia when it is put into mosquitoes really reduces the ability of the (dengue) virus to grow in the mosquito and if it can't grow, then it can't get transmitted in people," O'Neill told reporters.O'Neill said while it was too early to say if the experiments heralded the end of dengue fever, it was a major step towards that goal.In the past decade, there have been 2400 cases of dengue fever reported during 36 outbreaks in Australia.Dengue fever has become endemic in tropical regions, where it is spread by a specific type of mosquito that becomes infected after biting humans with the disease.Despite millions of people being infected with dengue each year, there is currently no way of stopping its rapid spread either by vaccines or controlling mosquito populations.Further trials will be conducted in Cairns in north Queensland over the coming wet season and approval is currently being sought for trials in Thailand, Vietnam, Brazil and Indonesia that will directly determine the effectiveness of the method in reducing dengue disease in human populations, according to Monash University.
