LOS ANGELES, Oct. 3 (Xinhua) -- An organizer of the World Stem Cell Summit says one of the key problems medical researchers face these days is how to apply their findings in the real world."How do you take the phenomenal scientific research going on in labs and translate it into medical treatments,?" said Bernie Siegel, the founder and co-chair of the summit and executive director of the Genetic Policy Institute, which organized the event."It's a big job to do this, and more than just the science," Siegel said, noting that in a growing field now moving beyond basic lab research, the aim is to connect the people who do the work with those who finance it.The three-day summit, which opened Monday in Pasadena, features more than 150 top international speakers and 50 hours of programming with leaders from science, pharmaceutics, business, policy, ethics, law and other fields.The cell therapy industry, a "nascent" field, has emerged to be a potentially multi-billion business with unlimited potential, Siegel said.Stephen Dalton, a University of Georgia professor, reported that one of the biggest developments in stem cell research in the past year was the realization that cells can be transdifferentiated from one state to another without returning to a pluripotent state.Dalton said the principle was previously supported by a few isolated examples but it was not until 2010 that the idea was widely accepted.Mark Sussman, a professor from San Diego State University, called the identification of lung stem cells from human tissue samples capable of regenerating the highly complex and specialized structures of mature lungs a breakthrough in lung biology and regenerative medicine.He said results presented by the Anversa group in the New England Journal of Medicine demonstrate that human lung stem cells can be expanded in vitro and also retain the capacity to integrate into adult tissue upon introduction into mice.The study, Sussman said, has opened up an entirely new field of possibilities for lung regeneration and potential therapeutic applications for many conditions where treatment options are either very limited or nonexistent.

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.

SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.
