Overall, rates of severe or fatal gastrointestinal bleeding are very low under the age of 70, but increased sharply after that age. Another side-effect of aspirin use is peptic ulcer, the risk which is elevated by 30-60 percent. The study also uncovers uncertainty over the most appropriate dose of aspirin necessary to maximize the power / harm ratio, with doses varying between 75 mg to 325mg a day time in various clinical trials and studies. It is also not yet determined whether taking aspirin for much longer than 10 years shall bring about greater benefits. Professor Jack Cuzick, Queen Mary University of London, comments: It has long been known that aspirin – one of the cheapest & most common drugs in the marketplace – can protect against certain types of malignancy.SkyScan 1272: This innovative high-resolution X-ray micro-CT 3D microscope for materials and life technology applications can visualize up to 200 Megapixel virtual slices through objects. More than 2,600 such slices could be reconstructed after an individual data acquisition in up to three offset positions. Using advanced contrast technology, the SkyScan 1272 can differentiate object information as small as 0. An optional 16-placement sample changer gives high throughput, even allowing the addition or replacement of samples without interrupting live scans.
