TEHRAN, Dec. 8 (Xinhua) -- Iranian inventors ranked first in the Seoul International Invention Fair (SIIF) in South Korea, the official IRNA news agency reported on Thursday.The three-member Iranian team from Tabriz city of Iran's northwestern East Azerbaijan province was ranked first by winning one gold and one silver medals in the fields of development and environment, said the report.South Korea, the United States and Chinese Taipei were selected as other three top teams after Iran.The Seoul International Invention Fair was held in the COEX Korea Exhibition Center from December 1 to 4, at which Some 700 participants from 32 countries and regions took part.

UNITED NATIONS, Oct. 17 (Xinhua) -- China on Monday underlined the importance of safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space, saying that "the outer space is the common wealth of mankind as the global public space."The statement came as Wang Qun, the Chinese ambassador for disarmament affairs, was taking the floor at the thematic debate on outer space at the First Committee of the UN General Assembly. The First Committee is in charge of disarmament and international security."The outer space is the common wealth of mankind as the global public space," Wang said. "The permanent peace of outer space is correlated to all nations' security, development and prosperity.""Meanwhile, with the growing reliance of mankind on outer space, the risk of the weaponization of and an arms race in outer space are on rise, and the uncertainties concerning outer space security are accumulating as well," he said. "Safeguarding the peaceful use of outer space and preventing the weaponization of and an arms race in outer space are common interest and obligations of all countries."In responding to the growing challenge for security in outer space, the international community also witnessed common grounds on opposing to the weaponization of outer space and advertising the Prevention of an Arms Race in Outer Space, he said.The General Assembly, for consecutive years, adopted " Prevention of an Arms Race in Outer Space" resolution by overwhelming majority of votes, calling for negotiations on an international legally-binding instrument on the prevention of an arms race in outer space at the Conference on Disarmament in Geneva."The mankind has marched into the 6th decade of outer space exploitation, and the manned space flight has made a history of 50 years," Wang said."Recently, China has successfully launched the Tiangong-1 ( Heavenly Palace 1) as a target spacecraft for rendezvous and docking experiment, which opens a new era of China's manned space flight, and also reflects that China is committed itself to the honorable objective of promoting the peaceful exploration and utilization of the outer space, maintaining peace and bringing benefit to mankind."

BEIJING, Otc. 26 (Xinhuanet) -- The more coffee people consume, the less likely they develop the most common form of skin cancer, a new study suggests, according to media reports Tuesday."Our study indicates that coffee consumption may be an important option to help prevent basal cell carcinoma," stated Fengju Song, lead researcher of the study and a postdoctoral fellow in the department of dermatology at Brigham and Women's Hospital and Harvard Medical School in Boston.Basal cell carcinoma (BCC) is reported to be a slow-growing form of skin cancer that accounts for 75 percent of all skin cancers. It is the most common type of skin cancer, with nearly one million new cases diagnosed each year in the United States.Although BCC is hardly fatal, if ignored, there may be consequences of treatment, including disfigurement, according to a USA Today report.The US researchers found that women who drank over three cups of coffee a day were 20 percent less likely to develop BCC, whereas the risk of having BCC for men who consumed more than three cups per day lowered 9 percent.To get the findings, the researchers analysed data from almost113,000 people between1984-2008 and over 23,000 were diagnosed with BCC.The researchers agreed that caffeinated coffee was associated with BCC risk reduction, but decaffeinated coffee did not have such effect.According to a Fox News report, besides cutting the risk of skin cancer, coffee consumption has also been found to lower the risk of breast cancer and prostate cancer and cancer overall."To the best of our knowledge, coffee consumption is a healthy habit," said Fengju Song, cited by the Fox News.The findings were presented Monday at the American Association for Cancer Research International Conference in Boston and not yet published in a scientific journal.

WASHINGTON, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.

WASHINGTON, Oct. 13 (Xinhua) -- In a trial that included about 35,000 men, those who were randomized to receive daily supplementation with vitamin E had a significantly increased risk of prostate cancer, according to a study published this week in the Journal of the American Medical Association.The study followed more than 35,533 men 50 or older at 427 sites in the United States, Canada and Puerto Rico. The men were divided into four groups who took daily doses of 400 international units of Vitamin E and 200 micrograms of selenium; Vitamin E and a placebo that looked like selenium; selenium and a placebo that looked like Vitamin E; or two placebos. The recommended daily intake of Vitamin E is about 22.4 international units.The researchers from the Cleveland Clinic found that the rate of prostate cancer detection was greater in all treatment groups when compared with placebo but was statistically significant only in the vitamin E alone group -- a 17 percent increased rate of prostate cancer detection. The difference in rates of prostate cancer between vitamin E and placebo became apparent during the participants' third year in the trial. The elevated risk estimate for vitamin E was consistent across both low- and high-grade disease."The observed 17 percent increase in prostate cancer incidence demonstrates the potential for seemingly innocuous yet biologically active substances such as vitamins to cause harm. The lack of benefit from dietary supplementation with vitamin E or other agents with respect to preventing common health conditions and cancers or improving overall survival, and their potential harm, underscore the need for consumers to be skeptical of health claims for unregulated over-the-counter products in the absence of strong evidence of benefit demonstrated in clinical trials," the researchers said.
