STOCKHOLM, Feb. 20 (Xinhua) -- The exhibition of the Chinese Terra-cotta Army here was an enormous success, project organizer Sanne Houby-Nielsen said Sunday.About 320 objects, including terra-cotta warriors from the ancient Chinese Qin Dynasty and other terra-cotta figures from Han Dynasty, were exhibited at the Far Eastern Antiquities Museum during the event, which ended Sunday.Houby-Nielsen, who is director of the museum and also director-general of the country's National Museums of World Culture, told Xinhua in an exclusive interview that the total number of visitors was around 350,000, more than double the expected turnout.This was the highest number of visitors the museum has ever experienced in its history since it was established in the 1940s, said Houby-Nielsen, adding that the exhibition was originally scheduled to end on Jan. 16, but "a great pressure from the audiences" prompted the museum to extend it till Sunday."It is an exhibition which won the most audience for many years in Sweden. We feel particularly happy because it was a very good display of the story of the first emperor and the early Han Dynasty," she said."We felt such a huge interest that we have to prolong it. So we were very grateful that it was possible to prolong the exhibition," she added.The exhibition was declared open by Swedish King Carl XVI Gustaf in August. Many of the ancient Chinese artifacts have never been exhibited outside China.Swedish Sinologist Cecelia Lindqvist commented that the event helped people understand the current China by looking at the history of China presented in the exhibition.

WASHINGTON, April 25 (Xinhua) -- A class of drugs that shows promise in breast and ovarian cancers with BRCA gene mutations could potentially benefit colorectal cancer patients with a different genetic mutation, a new study from the University of Michigan Comprehensive Cancer Center finds.Working in cell lines from colorectal cancer patients, researchers found that the class of drugs called PARP inhibitors worked against tumors with mutations in the MRE11 gene.About 15 percent of all colorectal cancers have what's called microsatellite instability, a type of error in the DNA. About 82 percent of those tumors have the MRE11 gene mutation."This is a potential broader application for PARP inhibitors, beyond breast and ovarian cancer. This is a class of drug that's already shown safety in early clinical trials and now might benefit some colorectal cancer patients as well," says lead study author Eduardo Vilar-Sanchez, a hematology/oncology fellow at the university, in a statement.The study, which was published Monday in Cancer Research, also found that PARP inhibitors are even more effective when both copies of MRE11 were mutated. Each person carries two copies of each gene, which means mutations can occur in either one or both copies. The researchers suggest that PARP inhibitors could be targeted specifically to colorectal cancer patients who have two copies of the mutated gene.Researchers are planning a phase I clinical trial to look at using PARP inhibitors in colorectal cancer patients with two mutated copies of MRE11. Future trials are being considered using PARP inhibitors to prevent colorectal cancer and other cancers in people with Lynch syndrome whose tumors have this mutation.Microsatellite instability is also seen in prostate cancer and endometrial cancer, suggesting potential for PARP inhibitors to play a role in additional types of cancer as well, Vilar-Sanchez says, adding that more research is needed in these areas.

LOS ANGELES, May 8 (Xinhua) -- Kids born in the spring and summer months might be more likely to develop celiac disease, U.S. researchers have found.Researchers from the Massachusetts General Hospital for Children drew the conclusion after examining data on 382 children diagnosed with celiac disease at between 11 months and 19 years of age, HealthDay News reported on Sunday.The study found that in the 15- to 19-year-old set, birth season appeared to make no difference, but among 317 children younger than 15 years of age, 57 percent were born in the "light" season of March through August, compared with 43 percent who were born in the "dark" season of September through February.The findings suggest that the higher incidence of this autoimmune disease may be related to a combination of seasonal and environmental factors, the report said.Celiac disease is a digestive disorder triggered by consuming the protein gluten, which is primarily found in bread and other foods containing wheat, barley or rye. It can damage the small intestine and make it difficult to absorb certain nutrients, causing problems ranging from abdominal pain to nerve damage.Even though the exact cause of celiac disease is unknown, potential triggers include the timing of infants' introduction to gluten, and viral infections contracted during the first year of life.The study's findings suggest the season of a child's birth is another potential risk factor for the disease.The researchers pointed out that infants are generally introduced to solid foods containing gluten at around six months of age, which for spring and summer babies would coincide with cold and flu season.Based on the findings, the age at which gluten is first offered to some babies may need to be altered, said the study's lead researcher, Dr. Pornthep Tanpowpong. "If you're born in the spring or the summer, it might not be appropriate to introduce gluten at the same point as someone born in the fall or winter," said Tanpowpong. "Although we need to further develop and test our hypothesis, we think it provides a helpful clue for ongoing efforts to prevent celiac disease."The study also noted that exposure to sunlight may also play a role in celiac disease, since vitamin D deficiency has been associated with the disease.The study was presented Sunday in Chicago during Digestive Disease Week, an international gathering sponsored by the American Gastroenterological Association and other organizations, HealthDay News said.Because the study was presented at a medical meeting and is small, its findings should be considered preliminary until published in a peer-reviewed journal and confirmed in other research, the report said.

BEIJING, Feb. 15 (Xinhua) -- A senior Chinese mainland official has said the government will work with Taiwan to enhance cross-Strait economic exchanges and cooperation.The mainland would this year focus on fulfilling the cross-Strait Economic Cooperation Framework Agreement (ECFA) and conducting follow-up negotiations on the pact, which took effect in September last year, Xu Mang, director of the economy bureau of the Taiwan Affairs Office of the State Council, told Xinhua in an interview.Top of the follow-up agenda was cross-Strait investment protection. The mainland hoped to reach a mutually beneficial agreement on the issue with Taiwan at an early date, with concerns of both sides respected, Xu said.Xu said the two sides should adhere to the principle of balance in negotiations, aiming for effective protection, fewer restrictions and more convenience for cross-Strait investment.Mainland and Taiwan negotiators agreed in December last year to continue discussing the investment protection agreement at the seventh round of talks scheduled for this year.The mainland would also continue this year to encourage investment in Taiwan, address Taiwan enterprises' concerns over economic transformation and development, and promote cross-Strait cooperation in finance, modern services and agriculture, Xu said.The first step in implementing the ECFA, the "early harvest program," took effect on Jan. 1, when the mainland reduced tariffs on 539 Taiwanese items, or 16 percent of imports from Taiwan, while Taiwan cut duties on 267 mainland items, 10 percent of imports from the mainland.Within two years, the duties on those products will be reduced to zero.Xu said the implementation of the early harvest program would boost trade links across the Strait.As the products receiving tariff reductions covered industries including agriculture, petrochemicals, machinery, textiles and transport, Taiwan businesses on the mainland would benefit from lower purchase costs on Taiwan raw materials, Xu said.Taiwan's small and medium-sized enterprises and low-income groups would especially benefit from the tariff reductions on exports of 18 agricultural products to the mainland, Xu said.Statistics from Taiwan showed that driven by the tariff reduction, the island's small and medium-sized enterprise export trade volume to the mainland would increase to 18 billion U.S. dollars per year."The tariff reduction policy will benefit more Taiwan compatriots," Xu said.Cross-Strait trade volume totaled 145.37 billion U.S. dollars last year, a rise of 36.9 percent year on year. The figure included 115.69 billion U.S. dollars of Taiwan exports to the mainland, up 20.2 percent. 

LOS ANGELES, April 1 (Xinhua) -- A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar is scheduled to depart Sunday, April 3 on a nine-day mission to image Hawaii volcanoes, the Jet Propulsion Laboratory (JPL) announced on Friday.The aircraft will fly from the Dryden Aircraft Operations Facility in Palmdale, California to the Big Island of Hawaii to study the Kilauea volcano that recently erupted, said JPL in Pasadena, Los Angeles.The mission will help scientists better understand processes occurring under Earth's surface, JPL said.Developed by JPL, the Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, uses a technique called interferometric synthetic aperture radar that sends pulses of microwave energy from the aircraft to the ground to detect and measure very subtle deformations in Earth's surface, such as those caused by earthquakes, volcanoes, landslides and glacier movements.As the Gulfstream-III flies at an altitude of about 12,500 meters, the radar, located in a pod under the aircraft's belly, will collect data over Kilauea, according to JPL.The UAVSAR's first data acquisitions over this volcanic region took place in January 2010, when the radar flew over the volcano daily for a week. The UAVSAR detected deflation of Kilauea's caldera over one day, part of a series of deflation-inflation events observed at Kilauea as magma is pumped into the volcano's east rift zone.This month's flights will repeat the 2010 flight paths to an accuracy of within 5 meters, or about 16.5 feet, assisted by a Platform Precision Autopilot designed by engineers at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, JPL said.By comparing these camera-like images, interferograms are formed that reveal changes in Earth's surface, said JPL.Between March 5 and 11, 2011, a spectacular fissure eruption occurred along the east rift zone. Satellite radar imagery captured the progression of this volcanic event."The April 2011 UAVSAR flights will capture the March 2011 fissure eruption surface displacements at high resolution and from multiple viewing directions, giving us an improved resolution of the magma injected into the east rift zone that caused the eruption," said JPL research scientist Paul Lundgren."Our goal is to be able to deploy the UAVSAR on short notice to better understand and aid in responding to hazards from Kilauea and other volcanoes in the Pacific region covered by this study," Lundgren added.
