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."

WASHINGTON, Dec. 12 (Xinhua) -- British scientists have discovered a new way to target cancer through manipulating a master switch responsible for cancer cell growth. The findings, published Monday in the U.S. journal Cancer Cell, reveal how cancer cells grow faster by producing their own blood vessels.Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumor. These proteins are vascular growth factors like VEGF -- the target for the anti-cancer drug Avastin. Making these proteins requires the slotting together of different parts of genes, a process called splicing.Scientists at the University of West England and the University of Bristol discovered that mutations in one specific cancer gene can control how splicing is balanced, allowing a master switch in the cell to be turned on. This master switch of splicing makes cancer cells grow faster, and blood vessels to grow more quickly, as they alter how VEGFs are put together.In experimental models, the researchers found that by using new drugs that block this master switch they prevented blood vessel growth and stopped the growth of cancers."The research clearly demonstrates that it may be possible to block tumor growth by targeting and manipulating alternative splicing in patients, adding to the increasingly wide armory of potential anti-cancer therapies," the authors said.

WASHINGTON, Oct. 19 (Xinhua) -- A total of 25 people have been killed in 12 U.S. states in a listeria outbreak traced to Colorado cantaloupes, the U.S. Centers for Disease Control and Prevention ( CDC) said Wednesday.The number of people sickened by the tainted cantaloupes has reached 123 in 26 states, with Pennsylvania reporting its first case. One of the ill patients, a pregnant woman, suffered a miscarriage, the CDC said in a telebriefing.The listeria outbreak has been the most deadly one since 1998, according to the CDC.Listeria is a common bacterium that typically causes mild illness in healthy people, but can cause severe illness in older people and those with compromised immune systems. It also can cause miscarriages and stillbirths in pregnant women and severe infections in new babies.The CDC estimates that about 48 million people in the U.S. each year get sick from tainted food, with about 128,000 hospitalized and 3,000 deaths.

UNITED NATIONS, Jan. 24 (Xinhua) -- China welcomes and supports all efforts and measures that would break the current deadlock of the Palestinian-Israeli negotiation and relaunch their dialogues, Chinese UN ambassador Li Baodong said here Tuesday.Li made the remarks when addressing a Security Council monthly open debate on Middle East."The Middle East peace process is currently in a stalemate. China is deeply concerned over the development," Li said."We always maintain that the parties concerned should resolve their disputes through political negotiations under the relevant UN resolutions, the principle of 'land for peace,' the Arab Peace Initiative and the Middle East Roadmap for Peace with the goal of ultimately establishing an independent Palestinian state and two states,Palestine and Israel, living side by side in peace," he said. China appreciates the efforts made recently by Jordan and Quartet of Middle East to facilitate the two parties to have direct contact, said Li, adding "We hope the relevant peace promotion efforts will help resume the Palestinian-Israeli peace negotiation sooner and achieve substantive result. China supports a greater role of the UN in resolving the Middle East issue."Calling the Israeli settlement "a major obstacle" for the resumption of Palestinian-Israel peace negotiation, Li said China is seriously concerned about the recent approval by the Israeli government of plans for expansion of new settlements."China is always against Israeli establishment of Jewish settlements in the occupied Palestinian territory including East Jerusalem. We urge Israel to cease the settlement construction immediately, be prudent in action and work actively in collaboration with the efforts of the international community to promote peace, and create conditions for the resumption Palestinian-Israeli peace negotiation," the ambassador said.China has always supported the Palestinian people in their just cause to restore the lawful rights of the nation, and maintained that establishment of an independent state is the lawful right of the Palestinian people as the basis for the implementation of the "two-state solution""China supports the establishment of an independent Palestinian state that enjoys full sovereignty, with East Jerusalem as its capital and based on the 1967 border. China supports Palestine's membership in the United Nation," Li said.The Syria-Israel track and the Lebanon-Israel track are important component of the Middle East peace process, and play an indispensable role in the overall settlement of the Middle East issue, Li said.China firmly supports the just cause of Syria and Lebanon to maintain sovereignty and territorial integrity, and recover their occupied territoriesChina supports the strategic choice made by Arab states in their pursuit of a comprehensive and lasting peace in the region, Li added.He also called on relevant parties to keep constrained, avoid the escalation of tension in Gaza, effectively implement relevant UN resolutions and fully lift the Gaza blockade.

BEIJING, Nov. 9 (Xinhua) -- A Chinese Mars orbiter named Yinghuo-1 was successfully launched on Wednesday morning from Russian-leased Baikonur cosmodrome in Kazakhstan, China's authorities said. The orbiter was launched by a Zenit-2 booster rocket at 4:16 a.m. Beijing time Wednesday (2016 GMT Tuesday), hitching a ride on Russia's Phobos-Grunt (Phobos-Soil) craft, an unmanned probe on Phobos, a moon of Mars, said China's State Administration for Sciences, Technology, and Industry for National Defence.
