Fact Sheet Protecting Workers from the Hazards of Abrasive Blasting Materials Abrasive blasting uses compressed air or water to direct a high velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture, or prepare a surface for the application of paint or other type of coating.
The most common gene associated with late-onset Alzheimer's disease is called apolipoprotein E (APOE). APOE has three common forms: 1  APOE e2 â the least common â appears to reduce the risk of Alzheimer's. 2  APOE e4 â a little more common â appears to increase the risk of Alzheimer's.
The work was funded by NIH's National Institute on Aging (NIA) and National Human Genome Research Institute (NHGRI), as well as by 18 other international public and private organizations. We do not fully understand what causes Alzheimer's disease, but we know that genetic factors can play a role, says NIA director Richard J. Hodes. M.D. Scientists have previously identified three genes, variants of which can cause early onset Alzheimer's, and one that increases risk for the late onset form.
