SAN FRANCISCO, Dec. 13 (Xinhua) -- A Nokia executive has claimed that the youth of today are fed up with the iPhone and baffled by Android, U.S. media reported on Tuesday."What we see is that youth are pretty much fed up with iPhones. Everyone has the iPhone. Also, many are not happy with the complexity of Android and the lack of security," said Niels Munksgaard, director of portfolio, product marketing and sales at Nokia entertainment global, in an exclusive interview with technology news site Pocket-lint.He added that the youth today want to try something new and are turning to the Windows phone platform.Many tech bloggers and industry critics said Nokia, the once leader who is eager for a comeback in the mobile industry, should not trash-talk its competitors, noting that it should focus on breakthroughs like design, ecosystem of app developers to get back its place in the competition.Nokia has placed most of its bets on Windows phone platform as it introduced Lumia 800 and Lumia 710 in London in late October. It is also reportedly testing the 4G version of Lumia 800 in the United States.

WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

WASHINGTON, Nov. 18 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy to E. coli derived asparaginase and pegapargase chemotherapy drugs used to treat ALL.Acute lymphoblastic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes, a type of white blood cell. White blood cells help the body fight infection and are formed in the bone marrow.Erwinaze is injected directly into the muscle three times a week and works by breaking down one of the body's protein building blocks (the amino acid, asparagine) that is present in the blood, and is necessary for the growth of all cells. Leukemia cells cannot produce this protein building block. When a patient is treated with Erwinaze the leukemia cells die. Normal human cells are able to make enough asparagine for their own needs through biosynthesis and will not be affected by treatment with Erwinaze."The approval of Erwinaze underscores the FDA's commitment to the approval of drugs for conditions with limited patient populations with unmet medical needs using novel trial endpoints," said Richard Pazdur, director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research.Side effects associated with Erwinaze treatment include serious allergic reactions, inflammation of the pancreas, high blood levels of liver enzymes, blood clotting, bleeding, nausea, vomiting and high blood sugar.

BEIJING, Nov. 6 (Xinhua) -- Employment quality in China is relatively low, which is a major reason affecting the quality of economic growth, says a latest report on the labor market.The report, released Saturday by the Labor Market Research Center of the Beijing Normal University focusing on the quality of employment in China, says Beijing, Shanghai and Tianjin were the top three cities in terms of employment quality, adding the overall employment quality in China is still low."Poor employment quality in China is a major reason for the poor quality of economic growth," said Lai Desheng, a professor with the Beijing Normal University.

BAGHDAD, Nov. 15 (Xinhua) -- Iraqi President Jalal Talabani told the newly-arrived Chinese ambassador Tuesday that Iraq is willing to expand cooperation and strengthen ties with China.Talabani made the statement when receiving the credential from Ni Jian, China's new ambassador to Iraq, in his presidential palace.The friendship between Iraq and China can be traced back to more than a millennium ago and endured the test of time, Talabani said.The recent years have seen increasing cooperation and exchanges between the two countries in multiple fields, bearing positive results and breakthroughs, he said.Ni Jian said that China attaches great importance to the Chinese-Iraqi relations and is willing to broaden friendly ties with Iraq on the basis of equality and mutual benefit.
