On another call <a href=" http://crmk.co.uk/vermox-uk.pdf#pinching ">vermox uk </a> Robert Baan , a toxicologist and biochemist who organized the 2011 researchers, told U.S. News that Hamzany's study would not be a reason to rethink their conclusion. He critiqued the small size and scope of the data, noting, for example, that he would have liked details on the extent of correlation between oxidative stress levels and the most frequent cellphone users, and he expressed concern about the control group. "I don't know if being deaf has other affects on the saliva or on the physiology of the ear in general," he says. Still, Baan says Hamzany's research "raises questions, and it asks for more studies in this direction."
