WASHINGTON, Nov. 11 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved HEMACORD, the first licensed hematopoietic progenitor cells-cord cell therapy.HEMACORD is indicated for use in hematopoietic stem cell transplantation procedures in patients with disorders affecting the blood forming system. For example, cord blood transplants have been used to treat patients with certain blood cancers and some inherited metabolic and immune system disorders."The use of cord blood hematopoietic progenitor cell therapy offers potentially life-saving treatment options for patients with these types of disorders," said Karen Midthun, director of FDA's Center for Biologics Evaluation and Research, in a statement.HEMACORD contains hematopoietic progenitor cells (HPCs) from human cord blood. Cord blood is one of three sources of HPCs used in transplants. The other two are bone marrow and peripheral blood. Once these HPCs are infused into patients, the cells migrate to the bone marrow where they divide and mature. When the mature cells move into the bloodstream they can partially or fully restore the number and function of many blood cells, including immune function.

BEIJING, Oct. 28 (Xinhuanet) -- Taking aspirin everyday may lower the risk of developing colon cancer for people with the cancer-causing genes, researchers found.The finding was published on Friday in the British medical journal "Lancet".The researchers followed 508 patients with Lynch syndrome, an inherited disorder which increases the risk of developing colon and other cancers.These patients were divided into two groups: members in one group took 600 mg aspirins everyday; another group took only the dummy pills.After 4 years, 10 colon cancer cases were reported among 258 patients who took daily aspirins for at least two years, comparing with 23 cases among 250 patients on dummy pills."This is good news for a very specific population," said Asad Umar, a cancer prevention expert at the U.S. National Cancer Institute.However, the finding doesn't apply to the general public, suggested the lead author of the study John Burn, a geneticist at Newcastle University in England.Only those who are at risk of such diseases should consider taking aspirin regularly, such as people having a family history of colon cancer, he added.

ACCRA, Dec. 1 (Xinhua) -- The Ghanaian government allayed the fears of many here on Thursday that it would provide funding for the treatment of persons living with HIV/AIDS in the country.Vice President John Dramani Mahama affirmed this when he addressed a ceremony to mark this year's World AIDS Day at Obuasi, near Kumasi, 270 km north of the capital Accra.Mahama said should the Global Fund pull out of supporting the country, the government would partner with development partners to raise the 5.8 million U. S. dollars needed yearly for the treatment of HIV/AIDS patients."Government will work together with the Ghana AIDS Commission (GAC) and donor partners to ensure that people living with HIV/ AIDS have access to antiretroviral drugs."The Presidency is with you, and whatever we will do to win the fight against HIV/AIDS shall be done," Mahama said.Ghana's HIV/AIDS infection rate, according to official figures, has dropped from 3 percent to the current 1.5 percent, albeit with pockets of higher rates of infection among some populations in the country.Mahama called for more innovativeness in mobilizing resources to avoid the danger of retrogression.Director-General of the GAC Angela El-Adas announced that the Ministry of Health had pledged 2.5 million Ghana cedis (1.66 million dollars) out of the 5.8 million dollars needed for next year.Meanwhile, in the capital, the Ghana Network of Persons Living with HIV and AIDS (NAP+ GHANA) joined persons living with HIV (PLHIV) globally on Thursday to commemorate this year's World AIDS Day."We stand united with our fellow PLHIV and the global HIV and AIDS community by fully supporting the vision of 'Getting to Zero', " Charity Owusu Danso, vice president of NAP+ Ghana, said in a message here.Established in 2005, NAP+GHANA is a network of member associations of persons living with HIV/AIDS in Ghana to represent the views, hopes and aspirations of PLHIV across the country."We are extremely worried. Everyday, we receive reports from PLHIV across the country that anti-retroviral drugs are out of stock or that hospitals or clinics won't give HIV treatment to new patients because there aren't even enough drugs for existing patients, " the statement said.

BEIJING, Oct. 6 (Xinhua) -- China's first space lab module were in good condition and all tests went on "smoothly" during the past week, according to a statement issued by the country's space project authorities Thursday.The unmanned module, Tiangong-1, or Heavenly Palace-1, blasted off on Sept. 29 from Jiuquan Satellite Launch Center in northwest China's desert area.Tiangong-1 switched to the orbit of 362 kilometers high and had orbited the Earth for 109 times by 6:00 p.m. Thursday, the statement said.Tests on the module's remote control system, video/audio equipments, temperature/humidity sensors, docking facilities and other functions had been conducted successfully, it added.It also revealed that the Jiuquan Launch Center and other units were preparing for the launch of the Shenzhou-8 unmanned spacecraft, which is scheduled to join the Tiangong-1 later this year.Shenzhou-8 and Tiangong-1 are expected to perform China's first space docking at a height of 340 kilometers above the earth's surface.

JERUSALEM, Jan. 12 (Xinhua) -- An Israeli company has developed a system that scans the brain and provides a three dimensional image of the nerve cell connectivity to treat brain diseases like Alzheimer's or HDHD.The firm ElMindA trademarked a non-invasive system, the BNA ( Brain Network Activation), that helps doctors visualize the connectivity between nerve cells and synchronization that can even measure the severity of the patients condition from one day to another, the Israel21c news site reported on ThursdayBy creating a three-dimensional image of the brain while asking the patients to repeat an activity several times, BNA developers hope this system will become a regular way of diagnosing brain illnesses."Our vision is that every psychiatrist and neurologist in the world will routinely send every patient for BNA tests," said Dr. Eli Zangvil, ElMindA's strategic advisor for business development. "Our test would add information and aid in diagnostics in a way no other existing technology can do," he added.BNA could help doctors find out exactly at what stage of the disease patients and prescribe the exact medication for them."To do that, we must collect a lot of data," Zangvil said. "To say this person has a certain disease or condition, I have to be able to compare their pattern to a normal brain pattern of a person of the same age and gender." he said.Researchers hope to gather the amount of data they need to obtain FDA approval in the U.S. by the end of 2012, and start marketing it to hospitals by 2013.
