WASHINGTON, Oct. 3 (Xinhua) -- Overweight or obesity may put children at three times greater risk for high blood pressure than those of normal weight, according to researchers from the Regenstrief Institute and Indiana University (IU) School of Medicine.Their study will appear in the November issue of Hypertension: Journal of the American Heart Association with advance online publication on Monday.More than 1,100 healthy Indiana school children were followed for nearly five years. The researchers found that when body mass index (BMI) reached or exceeded the 85th percentile for the age and gender of the child -- designated as being overweight -- the risk of high blood pressure nearly tripled. Obesity was defined as a BMI percentile higher than 95th. BMI is a measurement of body fat calculated from weight and height.Among study participants, 14 percent of overweight or obese children were pre-hypertensive or hypertensive, compared with 5 percent of normal weight children. These findings were consistent across age, gender and race.The average age at time of study enrollment was 10.2 years. Each child was assessed approximately eight times during the course of the study. All were healthy children and none were taking medication affecting blood pressure."Higher blood pressure in childhood sets the stage for high blood pressure in adulthood," said Regenstrief Institute Investigator Wanzhu Tu, professor of biostatistics at IU School of Medicine, who led the study. "Targeted interventions are needed for these children. Even small decreases in BMI could yield major health benefits."The researcher also found that leptin, a protein hormone which is involved in body weight regulation and metabolism, was positively associated with increased blood pressure in overweight and obese children.

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.

JIUQUAN, Oct. 26 (Xinhua) -- China will launch the spacecraft Shenzhou-8 in early November at the Jiuquan Satellite Launch Center in northwest deseart area.The unmanned spacecraft is expected to perform China's first space docking with Tiangong-1, or Heavenly Palace-1, a space lab module that was launched in September from the same launch center.The spacecraft and its carrier rocket, an upgraded Long March-2F, were transferred on Wednesday morning on a 20-meter-wide railway to the launch pad.The launch pad is 1,500 meters away from the assembling and testing center. It took nearly two hours to complete the transfer.Technicians completed testing on the assembling of Shenzhou-8 and the rocket after they were delivered to the launch center at the end of August, said Lu Jinrong, the launch center's chief engineer.In the next few days, the launch center will continue testing the spacecraft and the rocket, and inject propellent before the final launch in early November, Lu said.The assembling, testing and transferring of the spacecraft and rocket were all conducted while they were vertical.Shenzhou-8 is capable of docking with the spacecraft Tiangong-1 in both manual and automatic modes.The Tiangong-1 space lab module is functioning smoothly in the orbit, and all equipment and experiments are going well, according to Lu. The module is ready for the docking task, Lu said.

BEIJING, Nov. 25 (Xinhua) -- The Ministry of Commerce (MOC) said Friday that it will start an investigation into the U.S. government's policy support and subsidies for its renewable energy sector over trade barrier concerns.The MOC will look into six renewable energy programs concerning wind, solar and hydroelectric energy in the states of Washington, Massachusetts, Ohio, New Jersey and California, the MOC said in a statement posted on its website.The investigation was applied for by the China Chamber of Commerce for Imports and Exports of Machinery and Electronic Products, as well as the new energy chamber of the All-China Federation of Industry and Commerce."The applicants argued that the U.S. government's policy support and subsidies for its renewable energy industry constitute a trade barrier, as they violate the rules of the World Trade Organization and have hindered and restricted the development of China's renewable energy sector," the statement said.The applicants requested the elimination of any negative influence from the U.S. government's policy support and subsidies in order to maintain a fair trade environment, according to the statement.The investigation will end before May 25, 2012, although it may be extended to August 25, 2012 under special circumstances, according to the statement.
