WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."

BEIJING, Jan. 8 (Xinhua) -- China canceled over one-third of all official ceremonies, seminars and forums last year in a bid to avoid extravagance or corruption in the use of public resources.Some 2,549 such activities proposed by governments or public institutions, or 37.7 percent of the total applications, which were deemed "ceremonial" and "unnecessary," were cut, saving 1.22 billion yuan (about 193.39 million U.S. dollars), said an official statement released Sunday.The statement was issued by the State Council's Office for Rectifying Malpractices, a ministry-level inter-agency supervisory body dedicated to eliminating administrative irregularities and abuse of power in government agencies, public institutions and major service sectors.Last year's inspections focused on activities co-funded by ministries and local governments, the statement said.The Chinese government agreed with the public that the soaring number of official celebrations, seminars and forums would cost plenty of money and manpower and exacerbate corrupt behaviors.In March, the State Council, or China's Cabinet, ordered 98 ministries and ministry-level government organs to make public their budgets and expenditures on official overseas visits, public vehicles and official receptions -- the "three public consumptions" that had triggered widespread public concern.Premier Wen Jiabao also repeatedly urged the country's government agencies to reduce administrative expenses, including cutting the number of meetings and documents printed.Official figures indicate that the country's crackdown on various forms of extravagant spending by officials saved the country 5.7 billion yuan in 2010.A blue book on China's conferences published in November estimated that the total output of the country's conference industry had reached nearly 1 trillion yuan. Companies made up half of this total, while a considerable portion came from the government and public institutions compared to other social organizations.

SANTO DOMINGO, Jan. 11 (Xinhua) -- The Dominican Republic and Haiti Wednesday launched a joint plan aimed at eliminating cholera, which has claimed more than 7,000 lives in both countries since October 2010.The efforts were backed by the World Health Organization (WHO), the Pan American Health Organization (PAHO), and the United Nations International Children's Emergency Fund (UNICEF), Dominican officials said.The plan, "Call to action: the Hispaniola without cholera", aims to improve sanitary and living conditions of the Haiti people who face herculean reconstruction work following a devastating earthquake in the country on Jan. 12, 2010, that killed 220,000 people and displaced over 1 million.Cases of cholera, an infection that causes severe diarrhea that can lead to dehydration and death, first appeared in Haiti in October, 2010.The epidemic has so far killed more than 7,000 people and left nearly 500,000 more sick in Haiti.It also killed 135 people in the Dominican Republic as of September 2011, according to Dominican health authorities.Some 500 million U.S. dollars will be invested in projects related to sanitization and the construction of infrastructure that has to do with waterworks in both nations in the long term.

WINDHOEK, Nov. 29 (Xinhua) -- An agreement on Economic and Technical Co-operation was signed here on Tuesday between the Chinese and Namibian governments.The agreement was signed after Namibian Cabinet ministers and officials from various ministries held talks with Chinese State Councilor Liu Yandong, who arrived in Namibia on Tuesday for a three-day official visit.Minister of Presidential Affairs Albert Kawana, who is the Acting Director-General (DG) of the National Planning Commission (NPC), and Ambassador of China to Namibia Wei Ruixing signed the agreement.The two also exchanged letters on the provision of office supplies and solar energy equipment to the Namibian government by the Chinese government.During their talks, Liu highly spoke of the steady, healthy development of the relations between the two countries.She said the substantial cooperation have been obtained on agriculture, mining and human resources. Great achievements have been made in exchanges of culture and education.The state councilor also said China would like to work together with all African countries including Namibia to promote the development of people-to-people exchanges.Namibia's Deputy Prime Minister Marco Hausiku proposed future cooperation with China in visual and performing arts.He said the Directorate of Arts in the Ministry of Youth, National Service, Sports and Culture is keen to develop future relationships that will lead to bilateral exchanges in arts education, assistance in the development of small arts businesses, the promotion of arts through the exchange of information on arts and participation in events in the respective countries."This can be achieved through the development of ties between the relevant institutions responsible for these areas, such as the line ministries responsible for arts, arts education colleges, performance theaters, art galleries and organizers of events such as festivals and expos," he noted.He also encouraged exchanges between musicians in the sphere of composition, conducting, and instrumental playing in both folklore and symphonic genres, and therefore invited China in the development of Namibia's National Symphony Orchestra.Hausiku also proposed for scholarships in information and communication technology (ICT), particularly policy development and regulatory framework, and linkages with Chinese ICT institutions for exchange purposes.

MOSCOW, Oct. 3 (Xinhua) -- A Soyuz-2.1B rocket carried a Glonass-M navigation satellite into orbit early Monday after a two-day delay caused by high winds, a Russian Space Forces spokesman said."The launch of the booster rocket is as scheduled. The satellite Glonass-M was put into the orbit under control at 03:55 Moscow time (2355 GMT on Sunday)," said Colonel Alexei Zolotukhin.Zolotukhin told reporters that the rocket was launched at 0:15 Moscow time (2015 GMT, Sunday) from the Plesetsk Space Center in northern Russia.The Russian Space Forces said the launch was initially scheduled for Saturday but was postponed due to high winds.Glonass is the Russian equivalent of the U.S. Global Positioning System (GPS), which is designed for both military and civilian use. The system requires 24 operational and 2-3 reserve satellites in orbit to ensure global coverage.In December 2010, a malfunction of the booster resulted in a loss of three Glonass satellites.
