BEIJING, Aug. 24 (Xinhuanet)-- A new study shows that a diet rich in cholesterol-friendly foods, such as soy products and tree nuts, can decrease LDL (bad) cholesterol significantly, according to media reports on Tuesday.The study, published in the Journal of the American Medical Association, found that people who ate a healthy diet filled with cholesterol-lowering foods experienced a 13 percent decrease in their LDL cholesterol levels.For patients with high levels of so-called bad cholesterol, doctors usually have two prescriptions: cholesterol-lowering statin drugs and a diet that cuts out foods high in saturated fat, such as ice cream, red meat and butter.But the new study found that when it comes to lowering artery-clogging cholesterol, what you eat may be more important than what you don't eat.David Jenkins of St. Michael's Hospital and the University created the "portfolio diet," which includes regular consumption of tree nuts and high amounts of fiber from oats, barley and vegetables. The diet, which replaces butter with plant sterol-enriched margarine and substitute soy-based products for meat, allows maximum benefit in lowering cholesterol and preventing heart disease. "The study highlighted the power of food to lower risk for cardiovascular disease: What you do eat and what you don't eat are both important," said Dr. Jane Klauer, a New York internist specializing in metabolism and nutrition.A high overall cholesterol level makes a person nearly twice as likely to suffer a heart attack or stroke as someone whose total cholesterol falls into a healthy range.

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.

MOSCOW, June 15 (Xinhua) -- Russia's Mission Control announced on Wednesday it had raised the International Space Station (ISS) by 10.2 km to 374.7 km with the help of the Europe's ATV-2 Johannes Kepler.The Mission Control conducted the correction to the ISS at 19: 55 Moscow time (1555 GMT) by the boosters of the ATV-2 Johannes Kepler. The correction had lasted for some 40 minutes.According to the Mission Control, the correction was made in line with the ISS's ballistic flight program.On June 12, the Europe's second Automated Transfer Vehicle (ATV) Johannes Kepler has conducted two similar operations, raising the ISS orbit by 19.2 km to 364.6 km.Corrections to the space station's orbit are conducted periodically before launches of Russian cargo ships and U.S. shuttles to compensate for the Earth's gravity and to safeguard successful dockings.According to the Mission Control, the ATV-2 Johannes Kepler is scheduled to undock from the ISS on June 21.

RAMALLAH, Aug. 26 (Xinhua) -- China's special envoy to the Middle East, Wu Sike, said here Friday that his country fully supports the Palestinians' right to establish an independent state in a balanced manner and through peace talks."China supports the Palestinian people and their cause. We also support the Palestinians to get the United Nations recognition of a Palestinian state on the lands occupied in 1967 with Jerusalem as capital," he told Xinhua in Ramallah.The envoy said peace talks with Israel are the best way to reach a settlement, adding that gaining UN recognition is not an alternative to peace negotiations.China supports a two-state solution -- Israel and an independent Palestinian state living side-by-side in peace and security, he said, noting that he believes the current developments in the Middle East have a positive impact on the Palestinian cause."The Middle East witnesses many changes. People have many chances to participate in political life. The Palestinian cause is a main issue that attracts the attention of the Arab people," he said."The recent meeting of the Arab League Peace Initiative Follow- Up Committee in Qatar assures the Arabs' support to the Palestinians' bid for full UN membership," he said. "This will help the Palestinians gain more international support."The Palestinians say they will approach the UN in September to get full membership of the world body as peace talks with Israel have long been deadlocked, a move disapproved by Israel and the United States.Wu expressed his appreciation of the reconciliation deal signed between Palestinian National Authority President Mahmoud Abbas' Fatah party and Hamas movements in Cairo in May."This move will help the Palestinians to have more countries on their side," he said.Wu said his Middle East tour was taking place at an important moment as the region is witnessing crucial changes, stressing that China respects the choices of the peoples."The Arab peoples are able to make their own decisions toward development," said the envoy.He also said the ties between China and the Arab countries are based on strong foundations, regardless of the changes taking place in the region.Wu met with Palestinian President Mahmoud Abbas and other officials Tuesday, the first day of his ongoing Middle East tour.This was Wu's second visit to Palestinian territories this year, after which he will travel on to Israel, Egypt and France.

CANBERRA, Sept. 23 (Xinhua) -- A genetic study on Friday found Aboriginal Australians are descended from the first people to leave Africa up to 75,000 years ago.Researchers from the University of Western Australia, Murdoch University and an international team analyzed genetic material of a 100-year-old West Australian Aboriginal man's hair, and found he was directly descended from a migration out of Africa into Asia.The study revealed that Australian Aboriginal ancestors split from the first modern human populations to leave Africa, between 64,000 and 75,000 years ago, at least 24,000 years before other human migrations.According to Dr. Joe Dortch, an archaeologist at the University of Western Australia, the discovery rewrites the history of the human species by confirming humans moved out of Africa in waves of migrations rather than in one single out-of-Africa diaspora.It also rewrites the story about how Aborigines arrived in Australia some 50,000 years ago."So far there are no [archaeological] sites that are over 50, 000 years old so it puts a time limit on that and focuses our future efforts," he said in a statement released on Friday.Dr. Dortch believes the finding will foster a sense of pride in modern Australian Aborigines."No-one else in the world can say 'I am descended from people who have been here 75,000 years'."Associate Professor Darren Curnoe, leader of the Human Evolutionary Biology Lab in the School of Biological, Earth & Environmental Sciences at the University of New South Wales, said the study powerfully confirms that Aboriginal Australians are one of the oldest living populations in the world, certainly the oldest outside of Africa."Australians are truly one of the world's great human populations and a very ancient one at that, with deep connections to the Australian continent and broader Asian region. About this now there can be no dispute," he told Xinhua in an email note.Meanwhile, Professor Alan Cooper, Director of the Australian Centre for Ancient DNA (ACAD) at the University of Adelaide, said while this is a major step forward, the key unresolved question remains the unique story of Aboriginal history within Australia, such as what has happened in those 50,000 years of life in the harsh Australian environment."Unfortunately, the information from a single individual tells us very little about this fascinating, and critically important part of human history. Aborigines are one of the oldest continuous human populations outside Africa, as they note in the paper, and due to the geographic isolation and limited archaeological records remain one of the most mysterious chapters in human history," he told Xinhua on Friday.The study is published on Friday in the journal Science.Indigenous Australians are the original inhabitants of the Australian continent and nearby islands. They together make up more than 2.5 percent of Australia's population.
