VIENNA, March 28 (Xinhua) -- Stress hormone is helpful in alleviating acrophobia, a morbid fear of great heights, according to a study by Austrian scientists.They published the findings in the recent Proceedings of the National Academy of Sciences of the United States of America.Frank H. Wilhelm, professor from the Department of Clinical Psychology, Psychotherapy and Health Psychology at the University of Salzburg, Austria, carried out the first study demonstrating the clinical effectiveness of hormones released at periods of high stress in anxiety.The study found hormones and other drugs could be a good addition to behavioral treatment of several anxiety disorders.People with acrophobia have formed a so-called fear memory, which could be activated when the fear-causing stimulus occurs. They tend to react with feelings of extreme fear and anxiety to the ride in a glass elevator.Hence, scientists conducted a confrontation therapy, trying to mask this memory.A total of 40 experimental subjects had been put in a safe environment to constantly confront the fear-inducing stimulus, until they had a new reaction to the perceived threat.Observations also suggested hormones released in high stress had impact on learning and memory.Additionally, stress hormones were believed to facilitate the storage of new, anxiety-free competence and experienced confidence in the therapy. Animal studies have shown that this emotional relearning benefits from cortisol, one of the stress hormones.

SAN FRANCISCO, May 10 (Xinhua) -- Microsoft Corp. on Monday said it will buy Internet communications company Skype for 8.5 billion U.S. dollars in cash, a bold move for the software giant to explore new business opportunities."Skype is a phenomenal service that is loved by millions of people around the world," Microsoft CEO Steve Ballmer said in a statement."Together we will create the future of real-time communications so people can easily stay connected to family, friends, clients and colleagues anywhere in the world," he added.Microsoft said it has agreed to buy Skype from the investor group led by Silver Lake, and the deal has been approved by the boards of directors of both companies.Skype will become a new business division within Microsoft, and Skype CEO Tony Bates will assume the title of president of the Microsoft Skype Division, reporting directly to Ballmer.The Skype deal ranks one of the biggest purchase in the 36-year history of Microsoft, which is struggling to compete in the fields of Internet and mobile phones beyond its dominance on personal computer software market.Founded in 2003 and based in Luxembourg, Skype offers a software application that allows users to make free or cheap phone calls and chats over the Internet with additional features including instant messaging and video conferencing.Numbers showed that Skype's 170 million connected users made over 207 billion minutes of voice and video conversations in 2010.Skype was acquired by eBay in September 2005, and then acquired by an investment group led by Silver Lake in November 2009.In a press release announcing the acquisition, Microsoft noted that the deal will increase the accessibility of real-time video and voice communications, generating significant new business and revenue opportunities, and enhancing its existing offerings of real-time communications products and services.Microsoft said Skype will support its devices like Xbox and Kinect, Windows Phone and a wide array of Windows devices, and it will continue to invest in and support Skype clients on non-Microsoft platforms.The acquisition is expected to obtain all required regulatory clearances within this calendar year, Microsoft said.

WASHINGTON, March 4 (Xinhua) -- New data suggest that the epilepsy drug Topamax (topiramate) and its generic versions increase the risk for the birth defects cleft lip and cleft palate in babies born to women who use the medication during pregnancy, the U.S. Food and Drug Administration (FDA) said Friday in a statement.Before prescribing topiramate, approved to treat certain types of seizures in people who have epilepsy, health care professionals should warn patients of childbearing age about the potential hazard to the fetus if a woman becomes pregnant while using the drug, the FDA said.Topiramate also is approved to prevent migraine headaches, but not to relieve the pain of migraines."Health care professionals should carefully consider the benefits and risks of topiramate when prescribing it to women of childbearing age," said Russell Katz, director of the Division of Neurology Products in the FDA's Center for Drug Evaluation and Research. "Alternative medications that have a lower risk of birth defects should be considered."Cleft lip and cleft palate, collectively called oral clefts, are birth defects that occur when parts of the lip or palate do not completely fuse together early in the first trimester of pregnancy, a time when many women do not know they are pregnant.The defects range from a small notch in the lip to a groove that runs into the roof of the mouth and nose, possibly leading to problems with eating, talking, and to ear infections. Surgery often is performed to close the lip and palate and most children do well after treatment.Data from the North American Antiepileptic Drug (AED) Pregnancy Registry indicate an increased risk of oral clefts in infants exposed to topiramate during the first trimester of pregnancy. Infants exposed to topiramate as a single therapy experienced a 1.4 percent prevalence of oral clefts, compared with a prevalence of 0.38 percent - 0.55 percent in infants exposed to other antiepileptic drugs.Infants of mothers who did not have epilepsy and were not being treated with other antiepileptic drugs had a prevalence of 0.07 percent. Similar data from the United Kingdom Epilepsy and Pregnancy Register supported the North American AED Pregnancy Registry data.According to the FDA, before starting topiramate, pregnant women and women of childbearing potential should discuss other treatment options with their health care professional.
