Those plaques contain billions of copies of amyloid beta all stuck together in one gloppy mess.

这些斑块含有数十亿的：-淀粉样蛋白拷贝，它们乱七八糟地堆积在一起形成一个糊状的大块。

One of the most promising is to inhibit an enzyme that shears off amyloid beta from a larger protein.

最优希望的一种就是抑制一种将β淀粉状蛋白从大蛋白中剪切下来的酶。

Amyloid beta itself might be injuring nerve cells or the plaques, made of accumulations of amyloid beta, could be the culprits.

淀粉样β蛋白本身可能损伤神经细胞或者有它聚集形成的老年斑才是罪魁祸首。

The method combines an examination by positron emission tomography with a drug that lights up beta-amyloid.

Researchers in Iceland identified a rare genetic mutation that slows the activity of an enzyme called beta secretase, which is required to produce amyloid-beta.

As a result, the concentration of amyloid-beta increases and begins to form deposits, known as amyloid plaque, in the brain.

The next year Golde, at the Mayo Clinic, and his collaborator Edward Koo, at uc, San Diego, showed--at least in the test tube--that high doses of ibuprofen and other anti-inflammatories could lower production of amyloid-beta-42, which was believed to be a bad type of amyloid.
