Electro-Medicine : Biological Physics – The Molecular Basis of Alzheimers Disease – Video



13-03-2012 19:27 Research @ New insights on what causes Alzheimers disease could arise from a recent discovery made by bioengineers from the University of California, San Diego. The finding concerns the infamous amyloid beta peptides (A?)—fragments of which form plaques thought to play a role in Alzheimers disease. The bioengineers found that amyloid beta peptides (A?) spontaneously trigger calcium waves in purified cultures of astrocyte cells extracted from the cortex region of rat brains and grown in the lab. These calcium waves could be relevant for understanding the origin of Alzheimers disease. The accumulation of Amyloid beta fragments and sustained disruption of the calcium balance within cells are leading hypotheses for what causes Alzheimers disease. Mice on cell phones: The study involved 96 mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimer's disease as they aged. Some mice were left as-is, so researchers could test the effects of the radiation on normal memory as well. Both the Alzheimer's and normal mice were exposed to the electromagnetic field generated by standard cell phone use for two 1-hour periods each day for seven to nine months. They were housed in cages arranged around a centrally-located antenna that generated a cell-phone signal. The cages were arranged at the same distance from the antenna and exposed to the ...
