MANILA, June 14 (Xinhua) -- At least 200 people, mostly children, have been taken to hospitals after allegedly suffering from food poisoning at a birthday party in the northern Philippine province of Bulacan, local newspaper Manila Bulletin reported Tuesday.Most of the victims suffered from stomach and chest pains, diarrhea and vomiting, local health officer Dr. Rizalli Lucas was quoted as saying.The victims claimed the cause of their food poisoning was the spaghetti served during a birthday celebration over the weekend in a village of Calumpit town.James P. de Jesus, mayor of Calumpit, said the situation is now contained and controlled but they still have to implement health measures and to determine the cause of the alleged food poisoning.Police have started investigating the incident.

WASHINGTON, Aug. 2 (Xinhua) -- The weakness of aging is associated with leaky calcium channels inside muscle cells and a drug already in Phase II clinical trials for the treatment of heart failure might plug those leaks, according to a report published Tuesday in the online edition of Cell Metabolism.Earlier studies by the research team led by Andrew Marks of Columbia University showed the same leaks underlie the weakness and fatigue that come with heart failure and Duchenne muscular dystrophy."It's interesting, normal people essentially acquire a form of muscular dystrophy with age," Marks said. "The basis for muscle weakness is the same." Extreme exercise like that done by marathon runners also springs the same sort of leaks, he added, but in that case damaged muscles return to normal after a few days of rest. A microscopic view shows smooth muscle cells derived from human embryonic stem cells showing the nuclei (blue) and proteins of the cytoskeleton (green) in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009The leaks occur in a calcium release channel called ryanodine receptor 1 (RyR1) that is required for muscles to contract. Under conditions of stress, those channels are chemically modified and lose a stabilizing subunit known as calstabin1.Calcium inside of muscle cells is usually kept contained. When it is allowed to leak out into the cell that calcium itself is toxic, turning on an enzyme that chews up muscle cells. Once the leak starts, it's a vicious cycle. The calcium leak raises levels of damaging reactive oxygen species, which oxidize RyR1 and worsen the leak.The researchers made their discovery by studying the skeletal muscles of young and old mice. They also showed that 6-month-old mice carrying a mutation that made their RyR1 channels leaky showed the same muscular defects and weakness characteristic of older mice.When older mice were treated with a drug known as S107, the calcium leak in their muscles slowed and the animals voluntarily showed about a 50 percent increase in the amount of time spent wheel running. Now in clinical trials for patients with heart failure, the drug is known to work by restoring the connection between costabilin and RyR1.Despite considerable effort to understand and reverse age- related muscle wasting, there are no established treatments available. The new work suggests there may be hope in approaching the problem from a different angle."Most research has focused on making more muscle mass," Marks said. "What's different here is that we are focused not on muscle mass but on muscle function. More muscle doesn't help if it is not functional."

SAN FRANCISCO, June 22 (Xinhua) -- Apple Inc. plans to introduce a new iPhone in September featuring faster chip and more advanced camera, U.S. media reported on Wednesday.The new iPhone model, which will closely resemble iPhone 4, will include the A5 processor, a more powerful chip that Apple added to the iPad 2 tablet computer earlier this year, along with an 8-megapixel camera, up from the 5-megapixel model in the iPhone 4, Bloomberg quoted two people familiar with the product as saying.The device will run the iOS 5 operating system Apple previewed at its annual developer conference earlier this month.Aiming at attracting customers in developing countries, Apple is also working to finish a cheaper version of the iPhone which will use chips and displays of similar quality to the current iPhone 4, said the sources.Meanwhile, it was reported that Apple is also testing a new version of the iPad with a higher resolution screen, which, similar to the one currently used on iPhone 4, will be about one- third higher than iPad 2 and feature a more responsive touchscreen.According to a recent projection on smartphone market by the International Data Corp. (IDC), a small market share decline of iPhone is expected as the smartphone market matures and diversifies in 2011.The release of a new iPhone would help Apple gain more market share as smartphones powered by Google's Android system are predicted to grow to more than 40 percent of the market in the second half of this year.

BEIJING, Sept. 20 (Xinhuanet)-- Google's executive chairman Eric Schmidt is to face a Senate hearing on whether the company is abusing its dominance in Internet search, according to media reports on Tuesday.At the Wednesday's hearing before the Senate Judiciary Committee's antitrust panel, Schmidt will argue that critics are wrong to say Google gives preference to its own products, instead, Google is just trying to deliver the best-cultivated search results for users. The issue of search ranking is a touchy subject with Google, which says its algorithm is devised to give users the most useful result so they will come back.Another focal point of the hearing, which Schmidt concerned most is "scrapers", those who game its search algorithm, for example, taking commonly searched words, combine them into a nonsensical block of text and throw it up on the Web to grab eyeballs and advertising dollars.Google believes that, if scrapers succeed too often, consumers will lose confidence in search and turn to other resources, thus posing an existential threat to the company.Regulators in the U.S. and abroad have been looking into various aspects of Google's business practices since the company's 2007 purchase of ad firm DoubleClick. At the moment, European regulators are conducting an antitrust inquiry into Google's search business while the Federal Trade Commission is doing likewise. Google relies overwhelmingly on its core product, Internet search, and dominates the market for that product. It handles around two-thirds of U.S. Internet searches and more than 80 percent in many European countries, according to comScore Inc.
