SAN FRANCISCO, Nov. 1 (Xinhua) -- Apple announced on Tuesday that its latest iPhone 4S smartphone will be available in China's Hong Kong, South Korea and 13 additional countries next Friday.Customers will be able to pre-order iPhone 4S beginning this Friday, the Cupertino, California-based company said in a statement.The other 13 countries are Albania, Armenia, Bulgaria, El Salvador, Greece, Guatemala, Malta, Montenegro, New Zealand, Panama, Poland, Portugal and Romania.So far, some owners have been complaining about the shorter battery life on their new iPhone 4S handsets. Apple is reportedly investigating the issue and has not made official comments yet.The iPhone 4S looks the same as the previous iPhone 4 but has major hardware upgrade inside. Apple announced sales of more than four million units of iPhone 4S in the three days after its launch in the United States on Oct. 14.The iPhone 4S now is available in 29 countries and is expected to arrive in stores in more than 70 countries by the end of this year.
LOS ANGELES, Oct. 3 (Xinhua) -- An organizer of the World Stem Cell Summit says one of the key problems medical researchers face these days is how to apply their findings in the real world."How do you take the phenomenal scientific research going on in labs and translate it into medical treatments,?" said Bernie Siegel, the founder and co-chair of the summit and executive director of the Genetic Policy Institute, which organized the event."It's a big job to do this, and more than just the science," Siegel said, noting that in a growing field now moving beyond basic lab research, the aim is to connect the people who do the work with those who finance it.The three-day summit, which opened Monday in Pasadena, features more than 150 top international speakers and 50 hours of programming with leaders from science, pharmaceutics, business, policy, ethics, law and other fields.The cell therapy industry, a "nascent" field, has emerged to be a potentially multi-billion business with unlimited potential, Siegel said.Stephen Dalton, a University of Georgia professor, reported that one of the biggest developments in stem cell research in the past year was the realization that cells can be transdifferentiated from one state to another without returning to a pluripotent state.Dalton said the principle was previously supported by a few isolated examples but it was not until 2010 that the idea was widely accepted.Mark Sussman, a professor from San Diego State University, called the identification of lung stem cells from human tissue samples capable of regenerating the highly complex and specialized structures of mature lungs a breakthrough in lung biology and regenerative medicine.He said results presented by the Anversa group in the New England Journal of Medicine demonstrate that human lung stem cells can be expanded in vitro and also retain the capacity to integrate into adult tissue upon introduction into mice.The study, Sussman said, has opened up an entirely new field of possibilities for lung regeneration and potential therapeutic applications for many conditions where treatment options are either very limited or nonexistent.

BEIJING, Dec. 31 (Xinhua) -- In a New Year's address broadcast on Saturday, Chinese President Hu Jintao vowed that China will continue to develop friendly exchanges with other countries and positively participate in international cooperation on global issues.While addressing domestic and overseas audiences via state TV and radio broadcasters, Hu urged the acceleration of the transformation of the country's economic development pattern and structural adjustments while making more efforts in ensuring people's livelihood.The country will continue to balance maintaining steady and relatively fast economic growth with adjusting its economic structures and managing inflation expectations, he said in the speech titled "Jointly Improve World Peace and Development," which was broadcast by China Radio International, China National Radio and China Central Television.A photo released on Dec. 31, 2011 shows Chinese President Hu Jintao delivering a New Year address, titled "Jointly Improve World Peace and Development", to domestic and overseas audiences via state TV and radio broadcasters.China will stick to the guidelines of "one country, two systems," "Hong Kong people governing Hong Kong," "Macao people governing Macao," and a high degree of autonomy in maintaining the long-term prosperity and stability of Hong Kong and Macao, Hu said."We will adhere to the principles of 'peaceful reunification' and 'one country, two systems,' continue to push forward the peaceful development of cross-Strait relations, ensure the basic benefits for those of the Chinese nationality, and endlessly work for the common benefit of the compatriots on both sides of the Taiwan Strait," he said.2011 was the first year of the country's 12th Five-Year Plan period (2011-2015). In the face of complicated international situations and arduous tasks in maintaining domestic reform, development and stability, Chinese people united and continued to push forward the opening up and reform drive and the socialist modernization construction, while maintaining steady and relatively fast economic growth and making progress in building a well-off society in an all-around way, he said.China was also actively engaged in international cooperation to boost the growth of the global economy and financial stability, and it was involved in resolving international and regional issues, he said.The world is currently witnessing multipolarization and globalization, and various countries are increasingly interdependent, Hu said."However, the instability and uncertainty of the world economic recovery is on the rise, international and regional hot-topic issues have cropped up one after another, and the peace and development of the world faces unprecedented opportunities and challenges," Hu said.China will stick to peace, development and cooperation, adhere to independent foreign policy, maintain world peace and promote common development, Hu said.The country will stick to the principle of mutual benefit when opening itself up, he said."We will develop friendly cooperations with all countries on the basis of the five principles of peaceful co-existence, and we will continue to actively participate in international cooperation on global issues," Hu said."I believe that as long as people from all countries make efforts hand-in-hand, the world will have a better future and the welfare of the people of all countries will improve," Hu said.An article by Hu on boosting the country's cultural development will be published in Qiu Shi (Seeking Truth), an official magazine of the Communist Party of China Central Committee, on Jan. 1.
WASHINGTON, Dec. 7 (Xinhua) -- The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida.Their report, published on-line Wednesday in Gynecologic Oncology, suggests that this combination, ixabepilone and sunitinib, might offer a much needed treatment option for women with advanced ovarian cancer.Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it."Women die from ovarian cancer because their tumors become resistant to chemotherapy, so a drug that might be able to reduce that resistance -- which may be what this combination of agents is doing -- would be a boon to treatment of this difficult cancer," says study coauthor Gerardo Colon-Otero.The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. It might be a potential biomarker that may help identify patients who might benefit from such combination therapy, the researchers say.
BEIJING, Jan. 9 (Xinhua) -- The United States Treasury Secretary Timothy Geithner will discuss economic ties and exchange views with Chinese officials on the global economic situation during his trip to China, Foreign Ministry spokesman Liu Weimin said on Monday.Liu said at a regular press briefing that Geithner will visit China from Jan. 10 to 11 as the U.S. President's special representative. Premier Wen Jiabao, Vice President Xi Jinping, Vice Premier Li Keqiang and Vice Premier Wang Qishan will meet with him during the visit.Liu said China and the U.S. have agreed to build a partnership of cooperation based on mutual respect and mutual benefit."The global economic and financial situation is facing severe challenges. Further strengthening China-U.S. economic and trade cooperation will be helpful in meeting these challenges," Liu said."China has proposed further promoting the two countries' economic and trade cooperation and hopes the U.S. will work with China toward this end," Liu said.
