SAN FRANCISCO, Aug. 9 (Xinhua) -- Nokia is planning to stop selling its low-end phones and smartphones in the United States, instead focusing on products using Microsoft's Windows Phone platform, U.S. media reported on Tuesday.The Finnish handset maker will end sales of its low-end Series 40 phones and smartphones based on the Symbian mobile operating system in the United States and Canada, as it needs to put all of its efforts into the Windows Phone products which are due out later this year, Chris Weber, head of Nokia's U.S. subsidiary, told technology news site All Things Digital."When we launch Windows Phones we will essentially be out of the Symbian business, the S40 business, etc.," Weber said.Staff members speak to trade visitors at the Nokia booth at the CommunicAsia expo in Singapore June 21, 2011.In February, Nokia and Microsoft announced plans to form a broad strategic partnership, under which Nokia agrees to adopt Windows Phone as its principal smartphone strategy.North America is a priority for Nokia, Weber noted, in part because it is a key market for Microsoft and also because Nokia sees it as a key to winning in the smartphone battle globally."We'll develop for North America and make the phones globally available and applicable," Weber said.In another development, technology blog Engadget and other U.S. media on Tuesday reported that Nokia will not bring N9, its first smartphone running the Linux-based mobile operating system MeeGo, to the U.S. market."After the very positive reception to the launch of the Nokia N9, the product is now being rolled out in countries around the world. At this time we will not be making it available in the U.S., " Nokia said in a statement.

BEIJING, Aug. 1 (Xinhua) -- The after-tax CIF (cost, insurance and freight) price of China's jet fuel imports has been set at 7,768 yuan (1,206 U.S. dollars) per metric ton for August, China's economic planner said on Monday.The price adjustment marked the first time for the economic planner to adjust jet fuel prices on a monthly basis after it announced jet fuel pricing reforms in July, according to a notice posted on the National Development and Reform Commission (NDRC)'s website.The NDRC announced on July 7 that it would introduce a market-oriented jet fuel pricing mechanism starting from Aug. 1.Under the new mechanism, the ex-plant price of jet fuel is required to be no higher than the after-tax CIF price of jet fuel imports from Singapore, Asia's largest oil trading and storage center.Taking transportation expenses, trade volumes and international crude oil prices into account, the jet fuel premium is negotiable between jet fuel sellers and buyers and will be reviewed once a year, while jet fuel ex-plant prices will be adjusted on the first day of every month, according to the NDRC.

VANCOUVER, Sept. 18 (Xinhua) -- At the fourth International Qigong Tournament and Exchange currently going on in Vancouver, many of the competitors spoke Sunday of how the practice had improved their lives after being able to overcome the complications of illness and injury.While many of the more than 300 competitors in the eight-day tournament were out to demonstrate they were among the best practitioners in the world, others were clearly happy to be competing after previously living with various ailments that had affected their mobility and overall way of life."I've been very ill," said competitor Felicia Kazmer of the New Jersey-based U.S. Health Qigong Association. "I have Lyme disease and infections. I was out on medical for six months last year and through the practice of Qigong, and especially the intense practice because I knew we were coming to the tournament, I am feeling better than I have in years and years. I know that this has opened the meridians and allowed the qi to flow and it's worked better than any drug."While Qigong has been practiced in China for centuries, it is relatively new to the outside world. It is for this reason that after holding the biennial International Qigong Tournament and Exchange in China on the first three occasions, the event was moved abroad for the first time to help increase its awareness and growing popularity.Altogether, 44 Health Qigong teams are in Canada from 25 nations and regions for the tournament.Philip Moot, a 26-year-old from The Hague, was attending the tournament for a second time after taking in the last competition in Shanghai in 2009. Now studying Chinese acupuncture, the Dutchman said he took up Qigong after suffering from Pfieffer, a glandular fever that is a fatigue illness."I was always tired and when I woke up in the morning I felt already tired. Then I started with Qigong and exercises and it improved my health enormously. I'm doing it now, I think four years, and it made me stronger. The tiredness is gone."Moot said the more you put into Qigong, a series of movements and postures that focuses on regulated breathing techniques, focused meditation and self-massage, the more a person will get out of it.He compared the practice to charging up a battery and added he had now turned his parents on to Qigong, as well as a friend's father who is battling cancer. "It's helping him also to relieve the pain a little and not to think constantly of this disease."According to various clinical studies, the regular practice of Qigong has shown to be beneficial in reducing stress, better balance, lowering blood pressure, enhancing the immune system, improving sleep patterns, as well as improved cardiovascular, respiratory, circulatory and digestive functions, among many others.Depending on who you talk to, the benefits of Health Qigong means different things to different people, according to practitioner Susan Gallin. The New Jersey nurse took up the practice 18 months ago after undergoing knee surgery."But after the surgery my knee was never back to normal. So someone suggested to take Qigong," she said. "And I started taking it and it was amazing. I guess maybe after a couple of months my knee started to feel better and I'm not 100 per cent right now, but I do really well. I can squat down, things I couldn't do before the surgery."Working in the medical industry, Gallin said she was at odds with the western mentality of taking pills for everything. She felt hospitals should offer more wellness programs than they do."Some of the hospitals in the United States offer such things that include this type of alternative medicine, but I don't think it's enough. Some of the bigger pharmaceutical companies offer wellness programs before the hospitals and you would think we are in a healthcare system that they would offer a wellness (program), try to keep you well so you don't get sick. I know for myself I always try to do whatever I can before I take a pill."Reg Carter knows what it is like to endure a steady diet of pills after having to take anti-inflammatories and painkillers for problems with his joints. For the past two years the native Derby, England, has been practicing Qigong and was in Vancouver as part of the British team taking part."I had shoulder injuries, a broken collarbone, arthritis of several joints, elbows, my hands, fingers and the mobility has improved considerably since I've been doing the Qigong. The mobility has improved and also with the strengthening through the lower body and legs. The back injuries has improved. I don't get so much pain and I find I can move about a lot more fluidly," he said."I just feel like I've had a lot more life balance. I feel a lot more calmer. My sleep pattern's improved. I don't get angry so often, and if I do I find that I can get to grips with it and keep a lot calmer."Toronto resident Karen Widmer has never endured the pain suffered by Carter, but credits the energy of Qigong in aiding the recovery of a broken wrist she suffered four years ago while studying a level one Qigong course.Through regular practice, Qigong practitioners are said to be able to direct the energy in the body, the qi, towards the limbs."I completed it (the course) with a broken wrist and I could feel the energy repair much faster and the recovery time was better than they had actually thought," said the yoga instructor.Now totally hooked on Health Qigong and with 5,000 hours of practice to her credit, the 50-something Widmer explains it takes 10,000 hours of practice to achieve the title of "master.""While it looks like a physical process, it's actually very much more a spiritual process. Since we are electro-magnetic beings, it makes sense that we could send that current around in a positive way. But it does lead a person to longevity. It's a wellness that is authentic and I hope to be 100 years old and still doing it," she said."I have always enjoyed movement knowing that movement is health. And I would say that even people who aren't athletic can do this. It helps balance. Balance prevents falls, which prevents breakage. It is very beneficial to do this."

WASHINGTON, Aug. 4 (Xinhua) -- Researchers have found a way to turn mouse embryonic stem cells into sperm and this finding opens up new avenues for infertility research and treatment, according to a study published Thursday in the online edition of journal Cell,A Kyoto University team coaxed mouse embryonic stem cells into sperm precursors, called primordial germ cells (PGCs), and shown that these cells can give rise to healthy sperm. The researchers say that such in vitro reconstitution of germ cell development represents one of the most fundamental challenges in biology.When transplanted into mice that were unable to produce sperm normally, the stem cell derived PGCs produced normal-looking sperm, which were then used to successfully fertilize eggs. These fertilized eggs, when transplanted into a recipient mother, produced healthy offspring that grew into fertile male and female adult mice. The same procedure could produce fertile offspring from induced pluripotent stem cells that are often derived from adult skin cells."Continued investigations aimed at in vitro reconstitution of germ cell development, including the induction of female primordial germ cell-like cells and their descendants, will be crucial for a more comprehensive understanding of germ cell biology in general, as well as for the advancement of reproductive technology and medicine," the researchers wrote.

WASHINGTON, June 21 (Xinhua) -- A new study from Harvard School of Public Health (HSPH) and University of California, San Francisco, researchers suggests that men with prostate cancer who smoke increase their risk of prostate cancer recurrence and of dying from the disease. The study will be published Wednesday in the Journal of the American Medical Association."In our study, we found similar results for both prostate cancer recurrence and prostate cancer mortality," said Stacey Kenfield, lead author and a research associate in the HSPH Department of Epidemiology. "These data taken together provide further support that smoking may increase risk of prostate cancer progression."Kenfield and her colleagues conducted a prospective observational study of 5,366 men diagnosed with prostate cancer between 1986 and 2006 in the Health Professionals Follow-Up Study. The researchers documented 1,630 deaths, 524 (32 percent) due to prostate cancer, 416 (26 percent) due to cardiovascular disease, and 878 prostate cancer recurrences.The researchers found that men with prostate cancer who were current smokers had a 61 percent increased risk of dying from prostate cancer, and a 61 percent higher risk of recurrence compared with men who never smoked. Smoking was associated with a more aggressive disease at diagnosis, defined as a higher clinical stage or Gleason grade (a measure of prostate cancer severity). However, among men with non-metastatic disease at diagnosis, current smokers had an 80 percent increased risk of dying from prostate cancer.Compared with current smokers, men with prostate cancer who had quit smoking for 10 or more years, or who had quit for less than 10 years but smoked less than 20 pack-years before diagnosis, had prostate cancer mortality risk similar to men who had never smoked. Men who had quit smoking for less than 10 years and had smoked 20 or more pack-years had risks similar to current smokers."These data are exciting because there are few known ways for a man to reduce his risk of dying from prostate cancer," said senior author Edward Giovannucci, professor of nutrition and epidemiology at HSPH. "For smokers, quitting can impact their risk of dying from prostate cancer. This is another reason to not smoke."Prostate cancer is the most frequently diagnosed form of cancer diagnosed in the United States and the second leading cause of cancer death among U.S. men, affecting one in six men during their lifetime. More than two million men in the U.S. and 16 million men worldwide are prostate cancer survivors.
