BEIJING, Jan. 1 (Xinhua) -- State Grid Corporation of China (SGCC), the country's largest power supplier, said Sunday it has put to trial operation a cross-border electricity transmission project in northeastern Heilongjiang province to supply Chinese with Russia's electric power exports.The electric power SGCC purchased from Russia began reaching Chinese customers late Saturday night after the completion of the direct-current back-to-back networking substation, or called "the trans-Amur project" by Russians, SGCC said in a statement on its website.The trial operation will last 168 hours, SGCC said in the statement.With a transmission capacity of 750 mega-watts, the electricity transmission project is China's biggest cross-border power line, according to SGCC."The implementation of the project will gain experience for the expansion of Sino-Russian energy cooperation and help promote the economic development for both countries," SGCC said.The project is also part of the Sino-Russian energy and trade cooperation.Russian Deputy Energy Minister Andrei Shishkin said in June 2011 that the transmission project would increase Russia's power supply to five or six billion kilowatt hours of electricity to China and Russia intended to increase its electricity supply to China in the coming years.Russian companies plan export 60 billion kwh of electricity to China by 2020. Power plants will be built along its border with China to reduce power transmission losses and reduce transportation costs.Also on Sunday, an oil pipeline linking Russia's far east and northeast China witnessed its one year anniversary of operation, as operators announced an accumulated 15 million tonnes of oil had been transported into China in 2011.
SAN FRANCISCO, Oct. 10 (Xinhua) -- Apple announced on Monday that pre-orders of its iPhone 4S have topped 1 million in a single day, surpassing the previous single-day pre-order record of the company's smartphone.The iPhone 4S pre-orders surpassed 1 million in the first 24 hours and the previous single day pre-order record held by iPhone 4 is 600,000, according to Apple."We are blown away with the incredible customer response to iPhone 4S," Philip Schiller, Apple's senior vice president of worldwide product marketing, said in a statement."The first day pre-orders for iPhone 4S have been the most for any new product that Apple has ever launched and we are thrilled that customers love iPhone 4S as much as we do," he added.U.S., newly installed Chief Executive Officer Tim Cook takes stage to give a general introduction of Apple's products, Oct. 4, 2011. Apple Inc. last Tuesday unveils iPhone 4S, the much-anticipated latest generation of iPhone.The iPhone 4S, which looks the same as the iPhone 4 but has major hardware upgrade inside, is available for pre-order last Friday and set to first arrive in stores in the United States this Friday.So far, iPhone 4, which, according to Apple, has been sold more than the first three generations of iPhones combined, is Apple's best selling iPhone.The pre-order numbers are good news for Apple as the initial introduction of iPhone 4S last Tuesday has not lived up to the anticipation of some investors and analysts, and spurred a new wave of concerns about whether the company could keep its innovation momentum in the wake of the passing of its co-founder Steve Jobs last Wednesday.

KATHMANDU, Oct. 30 (Xinhua) -- "One of the major problems of death due to breast cancer in Nepal is poverty and untimely diagnosis," said Dr. Abish Adhikari Oncologist at the Bir Hospital in Nepali capital Kathmandu in an exclusive interview with Xinhua on Sunday.Adhikari said that the other reason why breast cancer leads to death of women is "women are not decision makers in their houses"."Many people who come here do not want to treat their wives or daughters because of the expenses as they are poor and it is really expensive here to treat cancer," Adhikari said.According to the Nepal Cancer Relief Society, of all cancer cases among the Nepali women and teenage girls as well, 60 percent is of breast cancer.Unverified rough data of the breast cancer patients in Nepal are above 50,000.Adhikari added that women are shy to talk about the problems of breast. They do not go to hospitals for the check up until they are bedridden and at the time they reach hospital they are mostly in the advanced stage.The major causes behind the breast cancer in Nepal are heredity, late pregnancy, consumption of alcohol and smoking. However, unawareness about it remains another major problem that leadind to death of many women in Nepal.Moreover, the rural women in Nepal are unaware about breast cancer, and if they are having some problem, they tend to hide it.Talking to Xinhua, Sajani Manandhar, General Secretary of Richa Bajimaya Memorial Foundation, a cancer awareness raising group said that the major cause of the preventable cancer in Nepal is unawareness.Also a nurse by profession, she said that no one bothers about mammography or regular checkup but are diagnosed at the very late stage.There are less than five hospitals that provide mammography service in the country.Roshani Chitrakar, 48 who is in advanced stage of cancer said that she did not told anyone while she found something unusual in her breast because it was not painful."I took it normally, but when I thought it might be a cancer and told my family and I was already in the advanced stage," she said.Her daughter, Roji Manandhar, said that the doctor has already told that she will not be living long. She is having difficulty even to eat currently.Another cancer patient, 67 years old farmer, Nakkali Nahakhusi said that she told her husband when she found her breast unusual. Her husband, former armyman, immediately took her to the hospital when she told about the problem.Now, she is already cured, and said with smilingly that the god of death did not want to take me away.She said that awareness should be raised because cancer is curable at the early stage.
WASHINGTON, Oct. 18 (Xinhua) -- Heart failure (HF) hospitalizations dropped 29.5 percent nationally over the past decade, according to a study by Yale physicians to be published Wednesday in the Journal of the American Medical Association.The risk-adjusted rate of heart failure hospitalization fell from 2,845 to 2,007 per 100,000 person-years from 1998 to 2008 in a fee-for-service Medicare claims analysis by Dr. Jersey Chen of Yale University and colleagues.The team also found that the rate of hospitalization for black men dropped at a lower rate, and that one-year mortality rates declined slightly during that period, but remained high.HF imposes one of the highest disease burdens of any medical condition in the United States and the risk increases with age. As a result, HF ranks as the most frequent cause of hospitalization and re-hospitalization among senior Americans. HF is also one of the most resource-intensive conditions, with direct and indirect costs in the United States estimated at 39.2 billion U.S. dollars in 2010.The study showed that the HF hospitalization rates varied significantly from state to state. The decline in the hospitalization rate from 1998 to 2008 was significantly higher than the national average in 16 states and significantly lower in three states (Wyoming, Rhode Island and Connecticut).Chen and his team also found that risk-adjusted one-year mortality decreased from 31.7 percent to 29.6 percent between 1999 and 2008, a relative decline of 6.6 percent, with substantial variation in different states."Because of the substantial decline in HF hospitalizations, compared to the rate of 1998, there were an estimated 229,000 fewer HF hospitalizations in 2008," said Chen in a statement, adding that with a mean HF hospitalization cost of 18,000 dollars in 2008, this decline represents a savings of 4.1 billion dollars in fee-for-service Medicare."The overall decline in the heart failure hospitalization rate was mainly due to fewer individual patients being hospitalized with heart failure rather than a reduction in the frequency of repeat hospitalizations," said Chen.
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.
