VIENTIANE, Dec. 5 (Xinhua) -- Laos and China pledged on Monday to deepen military exchanges and cooperation, strengthen unity and friendship between the two countries'militaries and work together to maintain regional peace and stability.The vows came out of the meeting between the Lao Deputy Prime Minister, Minister of National Defense Douangchay Phichith, Lao Deputy Minister of National Defense Sanyahak Phomvihane and the visiting Deputy Chief of General Staff of the Chinese People's Liberation Army (PLA) Cai Yingting.Douangchay said the Lao side appreciates the Chinese side's long-term support and help which have contributed to the Lao social economic development and national defense building. The Lao Party, government and military attach great importance to developing relations with China, and are willing to make joint efforts with the Chinese side to further promote the two states and militaries' ties to a new level.Sanyahak said that no matter how changes in the international and regional situation, the solid traditional friendship between the two countries' people and militaries won't change. Laos is willing to cooperate with China closely, deepen communication and cooperation between the two militaries, and constantly strengthen unity and friendship of the two sides.Cai said that China and Laos are friendly neighbors, the peoples of the two countries have forged a profound friendship since ancient times. In recent years, the bilateral ties continue to see a healthier and stabler development, especially after the two countries have established a comprehensive strategic and cooperative partnership.The Chinese side will continue to maintain close high-level contacts with Laos, enhance substantial cooperation, and strengthen friendly coordination, in order to contribute to the bilateral ties, and regional peace, stability and prosperity, Cai added.The Cai-led Chinese PLA delegation arrived in Lao's capital of Vientiane on Monday at the invitation of the Lao Ministry of National Defense, kicking off their friendly visit to Laos.

BEIJING, Oct. 27 (Xinhuanet) -- A new study shows that it's not simply a lack of willpower that explains weight regain but hormones keep one insisting on eating, a persistent biological urge. As any dieter knows, it's hard to keep weight off. Weight regain is a familiar problem for dieters. The research appears in Thursday's issue of the New England Journal of Medicine. To study what drives it, Proietto and his colleagues enrolled 50 overweight or obese patients in Australia in a 10-week diet program. On average, the participants lost almost 30 pounds in the 10 weeks - faster than the standard advice of losing a pound or two per week. Even so, they gained an average of 12 pounds back over the next year. The scientists checked the blood levels of nine hormones known to influence appetite - and found that even a year after the end of the weight-loss program, six of the hormones were still out of whack. People who regain weight should not be harsh on themselves, as eating is our most basic instinct, study author Joseph Proietto of the University of Melbourne in Australia said. It's better not to gain weight than to try to lose it.

WASHINGTON, Jan. 19 (Xinhua) -- New research published this week in Nature Medicine indicates that targeted drugs such as gefitinib might more effectively treat non-small cell lung cancer if they could be combined with agents that block certain microRNAs.The study, led by investigators with the Ohio State University Comprehensive Cancer Center, shows that overexpression of two genes called MET and EGFR causes the deregulation of six microRNAs, and that this deregulation leads to gefitinib resistance.The findings support the development of agents that restore the levels of these microRNAs. It offers a new strategy for treating non-small cell lung cancer, which is responsible for about 85 percent of the 221,000 lung-cancer cases and 157,000 deaths that occur annually in the United States. It also suggests that measuring the expression levels of certain microRNAs -- those controlled by the MET gene -- might predict which lung-cancer cases are likely to be resistant to gefitinib.Epidermal growth factor receptor (EGFR) is frequently overexpressed in non-small cell lung cancer, and this leads to uncontrolled cell proliferation. Gefitinib selectively inhibits EGFR activation and triggers cancer cells to self-destruct by apoptosis. However, non-small cell lung cancer cells inevitably develop resistance to the drug. The study reveals how this resistance occurs."Our findings suggest that gefitinib resistance that is caused by MET overexpression is at least partly due to miRNA deregulation, " says principal investigator Carlo Croce.

WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

UNITED NATIONS, Oct. 28 (Xinhua) -- China's progress in meeting a development goal on children's health can serve as an inspiration to other countries working towards the same objective, Dr. Renee Van de Weerdt, chief of maternal, newborn and child health at the UN Children's Fund (UNICEF) told Xinhua in an interview Friday.Van de Weerdt said that "the example of China is very encouraging because it means it can be done, even in a very big country with a very big population."China is on track to meet the fourth Millennium Development Goal (MDG), one of the eight development targets that the international community has pledged to meet by 2015. MDG 4 requires that each country reduce its rate of mortality for children under age five to two-thirds of what it was in 1990.According to Van de Weerdt, most deaths of children under five take place in the first month of life. After the first month, the most prevalent causes of death are pneumonia and diarrhea.ACHIEVING THE GOAL WORLDWIDEThe international community has been doing "relatively well" in working towards achieving MDG 4, Van de Weerdt said.The UN Interagency Group for Child Mortality Estimation (IGME) stated in their 2011 Report on Levels and Trends in Child Mortality that the number of under-five deaths worldwide has dropped from more than 12 million in 1990 to 7.6 million in 2010."We really continue to see progress," Van de Weerdt said. "The number of children that die every year continues to drop so we are really pleased to see that progress. Unfortunately, the progress isn't sufficient to really be able to say that if we continue at this pace we would achieve MDG 4 by 2015."Some regions, according to Van de Weerdt, like Latin America and parts of Asia are making more headway towards the goal than others that are currently lagging behind.
