VIENNA, April 12 (Xinhua) -- A protein group has been identified as an "allergy multiplier" that causes food allergy, a symptom that could also accompany other allergies and produce serious consequences, Austrian researchers said Tuesday.The so-called non-specific lipid transfer proteins (nsLTP) are believed to be the causes of food allergy, a research team from the Medical University of Vienna said in a new report.These plant allergens are found not only in many fruits and vegetables, but also in cereals and some types of pollen. Due to their compact structures, they are not degraded in the gastrointestinal tract and can trigger immune reactions that cause severe allergic symptoms, said the report.The researchers believe that with nsLTP identified as an " allergy multiplier," diagnostic and treatment procedures could be adapted and improved.

BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.

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."

JAKARTA, April 27 (Xinhua) -- Marine scientists will begin conducting an ecological survey in eight locations throughout the resort island in Indonesia's Bali province that could be developed as marine managed areas due to their biodiversity and coral structure, the Jakarta Post quoted an expert as saying on Wednesday.The survey, which will take place from April 29 to May 11, will be carried out by four international scientists and local scientists from universities.Ketut Sarjana Putra, the marine program director with Conservation International Indonesia, said Tuesday the survey was aimed at identifying marine species and their population in each of the eight locations.Selected from 25 potential marine conservation zones, the eight locations are Pulaki and Pemuteran, Lovina, Les Village, Tulamben and Amed, Padangbai, Nusa Penida, Bukit Uluwatu Peninsula and Perancak Beach. "We will go around Bali, starting from Sanur in the south, heading east, then covering the northern and the western areas, then back to the south," Ketut told the daily.The survey is part of a process to build a network of marine protected areas to effectively manage the island's marine and coastal resources to sustain environmental and socioeconomic value and benefits, with priority given to the eight locations.
