以淀粉作为膨胀阻燃体系中的成炭剂，取代或部分取代了膨胀型阻燃剂中的季戊四醇，研究了淀粉对膨胀阻燃剂及其与线性低密度聚乙烯膨胀体系的热降解行为和阻燃性。

Unlike previous models in which overexpression of the amyloid precursor protein results in amyloid plaque formation, have produced mice that overexpress only Aβ40 or Aβ42 and prove that Aβ42 is critical for the formation of amyloid deposits in vivo.

不同于早先调控淀粉样蛋白前体蛋白的动物模型，McGowan 等(Neuron， Vol 47， 191-199， 21 July 2005)培养了专一表达Aβ40或者 Aβ42的老鼠，结果直接证明了Aβ42 确实是引起淀粉样蛋白沉淀的主要因素，而不是Aβ40。
