13-09-22 Scientists at the Stanford University School of Medicine have shown how a protein fragment known as beta- amyloid（淀粉体） , strongly implicated in Alzheimer's disease, begins destroying synapses（突触） before it clumps into plaques that lead to n...

10-09-02 In Alzheimer's disease, the problem is beta- amyloid（淀粉体） , a protein that accumulates in the brain and causes nerve cells to weaken and die. Drugs designed to eliminate plaques（斑块，瓷片） made of beta-amyloid have a fatal problem: they need...

09-11-24 Alzheimer's disease is caused by the build-up of a brain peptide（肽） called amyloid（淀粉状肽）- beta. That's why eliminating the protein has been the focus of almost all drug research pursuing a cure for the devastating（破坏性的） neurodegenerat...
