Hamburger based his work on earlier discoveries of how the immune system causes allergic reactions. Researchers had determined that Immunoglobulin E (IgE), a blood fraction involved in fighting off invasions by foreign substances, is often present in abnormally large amounts in allergy victims. The Y-shaped molecules join with allergens such as pollens and then lock onto special sites on the surfaces of the connective tissue structures known as mast cells, causing them to release histamines, which in turn trigger allergy symptoms...

...Communists and the fellow-traveling M.D.P. (Portuguese Democratic Movement) with party representation in the Cabinet; the two groups had polled a mere 18% of the vote in last April's Constituent Assembly election, compared with 38% for the Socialists and 26% for the P.P.D.

He was a House master--but of the non-resident, catch all House. He graduated from Harvard, gaining a bona fide Ivy League background--but at the age of 31. And the particular...

...Consequently, in the process of national reconstruction after the war, nationalist politicians sought to project an image of a heroic France united behind de Gaulle and the Resistance Ophuls attempted to show that this image was a self-serving myth, since the Resistance never comprised more than a tiny fraction of the population, which for the most part collaborated actively or passively with the Vichy government and the Germans. Ophuls's interviews with survivors revealed a shocking absence of moral sensibility, even in retrospect. The most egregious instance was the case of a man incapable of understanding what was wrong...
