LOS ANGELES, March 23 (Xinhua) -- People who are more physically active are less likely to have high blood pressure associated with a high-sodium diet, a new study suggests.The study was conducted by researchers at the Tulane University School of Public Health and Tropical Medicine in New Orleans, HealthDay News reported on Wednesday.Study findings were presented at the on-going American Heart Association's meeting on nutrition, physical activity and cardiovascular disease, held in Atlanta, said the report.To explore a potential association between exercise and the hypertensive role of dietary salt, the researchers focused on roughly 1,900 men and women (average age 38) living in a rural region in northern China. None took blood pressure medication during the study, according to the report.For one week all of the participants consumed 3,000 mg of sodium a day in their diet; for another week, they were placed on a high-sodium diet -- 18,000 mg per day.Nine blood pressure readings were taken each week, and questionnaires were completed to assess routine levels of physical activity, ranging from "very active" to "quite sedentary."When switching from the lower-sodium to a high-sodium diet, those who experienced a 5 percent or greater boost in their systolic blood pressure (the heart contraction measure represented by the top figure of a blood pressure reading) were deemed "high salt-sensitive."Those reporting the most physical activity had a 38 percent lower risk of being highly salt-sensitive than the least active group. This group was the least likely to see a 5 percent or greater rise in their blood pressure in response to a high-salt diet.Compared with the most sedentary group, those in the next-to- highest activity group had a 17 percent lower risk of salt- sensitivity, and those in the next-to-lowest activity group had a 10 percent lower risk.The team concluded that engaging in physical activity has a " significant," independent and progressively healthful impact on the degree to which salt sensitivity relates to blood pressure."For those with low physical activity, their blood pressure will increase more if they increase their sodium intake," study co- author Dr. Jiang He, chair of the department of epidemiology at the school, said in remarks published by HeathDay News."It's a little bit of a surprise," He added. "But this is the first study to look at this particular association between physical activity and salt sensitivity and blood pressure. But after thinking it over it makes sense, because we already know that physical activity will reduce blood pressure."High blood pressure, or hypertension, is a leading cause of stroke. Because of salt's association with high blood pressure, the American Heart Association recommends consuming less than 1, 500 mg of sodium per day.

LOS ANGELES, March 27 (Xinhua) -- Walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut, U.S. researchers have found.Study findings were presented on Sunday at the 241st National Meeting & Exposition of the American Chemical Society (ACS) in Anaheim, Southern California.Nuts contain plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free, ACS researchers said in the study.Moreover, nuts contain healthful polyunsaturated and monosaturated fats rather than artery-clogging saturated fat, according to the study.The researchers based their conclusion on analysis of antioxidants in nine different types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias and pecans.They found that walnuts have the highest levels of antioxidants, with plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free.The latest study adds more evidence that walnuts are top nuts for heart-healthy antioxidants, the researchers said.Previous studies showed that regular consumption of small amounts of nuts or peanut butter can decrease the risk of heart disease, certain kinds of cancer, gallstones, Type 2 diabetes, and other health problems.But the latest study is the first to compare both the amount and quality of antioxidants found in different nuts."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who led the latest study."A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."

LOS ANGELES, April 12 (Xinhua) -- With the help of NASA Telescopes, astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, the Jet Propulsion Laboratory (JPL) announced on Tuesday.The finding addresses questions about when the first galaxies arose, and how the early universe evolved, JPL noted in a press release.Infrared data from both the Hubble Space Telescope and the post- coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed that the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler, said JPL in Pasadena, Los Angeles.This challenges theories of how soon galaxies formed in the first years of the universe and could even help solve the mystery of how the hydrogen fog that filled the early universe was cleared, according to astronomers involved in the study.This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity, JPL said.Normally, galaxies like this one are extremely faint and difficult to study, but, in this case, nature has provided the astronomers with a cosmic magnifying glass, JPL said.The galaxy's image is being magnified by the gravity of a massive cluster of galaxies parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing."Without this big lens in space, we could not study galaxies this faint with currently available observing facilities," said Eiichi Egami of the University of Arizona in Tucson. "Thanks to nature, we have this great opportunity to see our universe as it was eons ago."The findings may help explain how the early universe became " reionized," according to JPL."Seeing a galaxy as it appeared near the beginning of the universe is an awe-inspiring feat enabled by innovative technology and the fortuitous effect of gravitational lensing," Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington, said in the release."Observations like this open a window across space and time, but more importantly, they inspire future work to one day peer at the stars that lit up the universe following the big bang."

BEIJING, Feb. 8 (Xinhua) -- Forty people died in more than 118,000 cases of fire reported across China from February 2 to February 8, as Chinese revelers celebrated the Lunar New Year holiday with fireworks, according to a statement released Tuesday by the country's Ministry of Public Security.The number of cases jumped from the 7,480 fires reported during last year's Spring Festival holiday, which caused losses worth 28.5 million yuan. The incidents also injured 37 people and caused more than 56 million yuan (8.5 million U.S. dollars) in damages, which is almost double the figure from last year.However, this year's losses did not include a case in northeastern Liaoning Province where a five-star hotel in the city of Shenyang was set ablaze by fireworks on February 3.The fire, which caused no casualties, is possibly the country's largest fireworks accident during this year's Spring Festival celebrations.According to the statement, some 260,000 police and fire fighters across the country were mobilized for 24,800 fire control missions.The personnel rescued more than 1,600 people and evacuated tens of thousands. Fire departments have been strengthening monitoring of high-rise buildings, shopping malls, markets, construction sites and other crowded or vulnerable locations.Also, a total of 173 companies were suspended from operating for failing to meet fire prevention and control standards, according to the ministry.

LOS ANGELES, April 20 (Xinhua) -- Hundreds of homes were evacuated on Wednesday in Monument, U.S. state of Colorado after hydrochloric acid was leaking from a train car, authorities said.The leak was first reported around 1 a.m. local time when a southbound train spotted a vapor trail on a northbound train, the Denver Post reported.Authorities first ordered the evacuation of some 255 homes, and later expanded the evacuation to an additional 160 homes, according to the report.Schools in the area were closed due to the leaking, the report said.A specialized crew from Texas has been dispatched to the scene to transfer the hydrochloric acid leaking from the train car and is expected to finish the job in four or five hours, weather permitting, the report quoted Sgt. Mike Schaller of the El Paso County Sheriff's Office as saying.The leak is contained but hydrochloric acid is still leaking slowly from the tanker, which holds 25,000-30,000 gallons, Schaller said.He said police went door-to-door notifying residents of a subdivision adjacent to the railroad tracks to evacuate as a precaution.No injuries have been reported, he said, but residents have been warned that they may have to be out of their homes until Friday as hazardous material crews offload the acid to another container.The northbound train originated in Kansas and was en route to Denver at the time, the Denver Post said.It's not yet known how much hydrochloric acid leaked from the train car.Once the leak is sealed, crews will remove the hydrochloric acid from the damaged car to a new car that will likely continue into Denver, according to the report.Monument is a town of 3,230 residents 88 kilometers south of Denver.
