BEIJING, Dec. 11 (Xinhua) -- China is faced with severe challenges in collecting enough blood plasma to produce medicines, Health Minister Chen Zhu said Sunday.Chen called on the public to join blood donation after donating blood plasma at the Beijing Red Cross Blood Center on Sunday, the fifth time since he took office in 2007.Blood plasma is needed to make blood products like prothrombin complex which is vital for hemophiliacs.The total volume of blood plasma collected last year was 4,180 tonnes, while the volume needed to produce enough medicines was 8,000 tonnes, said a statement from the ministry. The situation became even worse this year.Donations of blood plasma in China fell dramatically in recent years, as a result of safety concerns from donors and the government's efforts to regulate blood collection after contamination triggered HIV infection scandals.In an overhaul of plasma collection services in 2004, the ministry closed 262 donation centers, leaving only 138 in operation, resulting in the plasma donations falling at least one-third from 5,000 tonnes in 2003.Blood plasma are currently collected at 144 designed stations across the mainland. The stations, as requested by law, are all owned by major manufacturers of blood products.Chen promised to encourage qualified drug makers to set up more collection stations in the next five years.He also assured the public the safety of blood donation at authorized stations.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

WUHAN, Oct. 8 (Xinhua) -- A museum that honors the 1911 Revolution, also known as the Xinhai Revolution, reopened Saturday after renovation to commemorate the centenary of the uprising at Wuchang in central Hubei province.More than 200 items that illustrate the revolution, such as photos, telegraphs, models and and simulative historic scenes, are on display.Located near the famous Yellow Crane Tower, the museum was once the headquarters of the revolutionary army.The movement's leader, Sun Yat-sen, overturned the ruling Qing Dynasty (1644-1911) after the revolution on Oct. 10, 1911 and founded the Republic of China in 1912.Commemorative gatherings were also held in provinces of Guangdong, where Sun was born, and Jiangsu, where the capital of the Republic of China was located.

SEOUL, Jan. 6 (Xinhua) -- LG Electronics, the world's No.2 TV maker, said Friday that it will showcase a smart TV that runs Google TV during next week's Consumer Electronics Show (CES) in Las Vegas.The LG-made Google TV powered by Google's Android operating system (OS) will be unveiled next Monday at the U.S. consumer electronics fair in Las Vegas, according to an e-mailed statement by LG.The Internet TV will offer its Android-based user interface, enabling consumers to enjoy web browsing and social networking, LG said. Multi-taking will also be available as the Internet surfing, social networking and TV functions can be run simultaneously.LG's three-dimensional (3D) technology will be available through its Google TV. With a single click of a remote controller, any two-dimensional (2D) program or movie can be viewed in 3D due to the built-in 2D to 3D conversion engine."Through Google TV, LG has merged Google's established Android operating system with LG's proven 3D and Smart TV technologies, offering consumers a new and enthralling TV experience," said Havis Kwon, chief executive of LG Electronics' home entertainment business.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.
