WASHINGTON, Oct. 3 (Xinhua) -- Researchers at St. Michael's Hospital in Canada have discovered a new function for an enzyme that may protect against organ injury and death from anemia, according to a study appearing Monday in the U.S. journal of the Proceeding of the National Academy of Sciences.Researchers found that when people have anemia, neuronal nitric oxide synthase (nNOS) -- an enzyme in nerve cells that produces nitric oxide, an important signaling molecule in the body -- increases the body's ability to respond, adapt to low oxygen levels and makes the body more efficient in delivering oxygen to tissues. They also found that levels of nNOS in the brain increased in anemic mice, and that the mice without this enzyme die earlier, and with higher hemoglobin levels."Identifying this mechanism may lead to new therapies and approaches to improving outcomes for anemic patients," said Dr. Greg Hare, a researcher at the Li Ka Shing Knowledge Institute of the hospital and one of the lead investigators of the study.Anemia occurs when blood has a lower than normal number of red blood cells or hemoglobin -- an iron-rich protein that carries oxygen from the lungs and heart to the rest of the body. Cells need oxygen to survive and to produce energy for all bodily functions. The condition has many different causes including infection (malaria, HIV, parasites), nutritional deficiencies (iron, folate, B12), genetic mutations, pregnancy, trauma and surgical blood loss."This research will help us identify when an anemic patient is at greatest risk for injury and death when undergoing surgery," said Hare. "Research is underway to test these findings in humans."

PARIS, Dec. 23 (Xinhua) -- French health authorities on Friday urged 30,000 women to remove the local-made breast implant, pledging that relevant expenses would be covered by the state.The health ministry said in a statement that they spot "no increased risk of cancer currently in women wearing the PIP (Poly Implant Prothese) brand compared with other implants.""However, well-established risks associated with these prostheses are rupture and irritant gel may lead to inflammatory reactions, making it difficult to explant," the statement added.French Health Minister Xavier Bertrand advised French women who have the PIP implants to get them taken out "as a preventive measure but not of an urgent nature." The removal of the implant will be at the state's expense.The recommendation came after eight cases, mainly breast cancer, were reported recently among women with PIP implants.The involved implant was produced by the French company PIP, once the world's third-largest producer of silicone implants who sold its products to tens of thousands of women in more than 65 countries, mainly in South America and western Europe.

PARIS, Oct. 1 (Xinhua) -- People come to the French capital will be able to enjoy a new public service by leasing electric cars in the urban region from Sunday.This car-sharing system is aimed to reduce the number of private cars as well as restrain pollution, according to the Paris municipal government.The plan, dubbed "the Autolib" system, is similar to already functioning "velib system" which is a large-scale public bicycle sharing system in Paris launched in 2007.The first experimental stage of the Autolib project is said to last two month with 66 cars at 33 stations around the city.Costumers can pay between 5 euros and 7 euros (6.7-9.4 U.S. dollars) for every half-hour use or register for a yearly, weekly or 24-hour package with different cost and necessary identity cards, driving licences and an uncashed deposit.Once fully charged, the four-seated "Bluecar" can reach a top speed of 130 km an hour and has a range of 250 km with a single charge.In order to encourage short journey rather than long trip around the capital, Paris administration wants to expand the system to a 250-car team by this December, and then to 2,000 by next summer.

SAN FRANCISCO, Nov. 11 (Xinhua) -- Facebook is close to a settlement with the U.S. Federal Trade Commission (FTC) over the charges that the world's largest social network misled users about its use of their personal information, the U.S. media reported Friday.The proposed settlement would require Facebook to get users' consent before making "material retroactive changes" to its privacy policies, said a report from The Wall Street Journal, citing people familiar with the talks.The agreement with the FTC is also expected to ripple much farther in the tech industry as more companies are developing programs to observe people's online behavior and profiting from the personal information, such as the target advertisements.With a current 800-million-user base worldwide, Facebook changed its user policy in late 2009 to disclose more of users' personal information without adequate notice, leading to a federal investigation along with mounting complaints online.On Thursday, two U.S. representatives asked the Palo Alto, California-based company to explain a February patent application, saying that it raises alarm bells about how the company tracks users on other websites.Outside the U.S., Facebook is also drawing criticism on its privacy policies in countries with strict privacy laws, such as Germany. On Thursday, German authorities said they are considering suing Facebook over its use of facial recognition technology.In a PBS interview aired earlier this week, Facebook's founder and chief executive officer Mark Zuckerberg and chief operating officer Sheryl Sandberg said the company is focused on privacy, addressing that it gives users the ability to protect their privacy.Zuckerberg said Facebook users volunteer all of their personal information on the social network, unlike other Internet giants and advertising networks that compile information "behind your back."
