MILAN, Italy, Dec. 1 (Xinhua) -- Italy has a new HIV infection every three hours on average, the national department of health said in a statement during the World AIDS Day commemoration Thursday.According to the statement, there were about 3,000 new infections in the country in 2010, with nearly one third of those affecting a foreigner.At least 157,000 people are presently estimated to be HIV-positive in Italy, though the country's AIDS infections and deaths continue to register a negative trend.Nearly 90 percent of the new patients acquired the virus through unprotected sex, and were mostly from the northern regions.People discovered to be HIV-positive in 2010 had an average age of 39 for men and 35 for women, more than a third of whom were diagnosed at an advanced stage of the disease, the statement said.Misinformation and a lack of preventive measures are a great cause for concern, Milan's councillor for social services and health Pierfrancesco Majorino told Xinhua at a campaign launched in Milan's La Scala Square."We have to keep in mind that AIDS is something very close to each of us, and adopt all most effective campaigns to provide complete and correct information," he said.A red ribbon -- the international symbol of AIDS awareness -- was formed by a group of people at the center of the square to remind everyone to stay alert to the disease.On World AIDS Day, disease prevention and health information campaigns were launched throughout Italy, including free ultra-rapid HIV-screening tests.

WASHINGTON, Nov. 24 (Xinhua) -- An inexpensive drug that treats Type 2 diabetes has been shown to prevent a number of natural and man-made chemicals from stimulating the growth of breast cancer cells, according to a newly published study by a Michigan State University researcher. The research, led by pediatrics professor James Trosko and colleagues from South Korea's Seoul National University, provides biological evidence for previously reported epidemiological surveys that long-term use of the drug metformin for Type 2 diabetes reduces the risk of diabetes-associated cancers, such as breast cancers.The research appeared online this week in PLoS One.For the study, Trosko and colleagues focused on the concept that cancers originate from adult human stem cells and that there are many natural and man-made chemicals that enhance the growth of breast cancer cells. Using culture dishes, they grew miniature human breast tumors, or mammospheres, that activated a certain stem cell gene. Then the mammospheres were exposed to natural estrogen -- a known growth factor and potential breast tumor promoter -- and man-made chemicals that are known to promote tumors or disrupt the endocrine system.The team found that estrogen and the chemicals caused the mammospheres to increase in numbers and size. However, with metformin added, the numbers and size of the mammospheres were dramatically reduced. While each of the chemicals enhanced growth by different means, metformin seemed to be able to inhibit their stimulated growth in all cases."While future studies are needed to understand the exact mechanism by which metformin works to reduce the growth of breast cancers, this study reveals the need to determine if the drug might be used as a preventive drug and for individuals who have no indication of any existing cancers," Trosko said.

SAN FRANCISCO, Nov. 28 (Xinhua) -- Amazon.com on Monday announced that this past Black Friday was the best ever for its Kindle products with consumers buying four times as many Kindle e- readers and tablets as they did last year.According to the online retail giant, its newly launched tablet Kindle Fire was the bestselling product across all of Amazon.com on Black Friday, the day after Thanksgiving, which falls on Nov. 25 this year, when major retailers in the United States traditionally offer big discounts.Kindle Fire is Amazon's answer to Apple's popular iPad. Priced at 199 U.S. dollars, the Amazon product is much cheaper than iPad which starts from 499 dollars.Survey results by research firm ChangeWave Research released days before Black Friday indicated that Amazon is poised to become the No. 2 player in the tablet computer market behind Apple, due to strong demand for Kindle Fire.Amazon said Black Friday sales also showed that a lot of customers were buying multiple Kindles, one for themselves and others as gifts.The trend is expected to continue through this holiday shopping season, Amazon's vice president of Kindle products Dave Limp said in a statement.

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.

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.
