Modern Occurrence
During the post-war period in Spain, there were several outbreaks of lathyrism, caused by the shortage of food, which led people to consume excessive amounts of Almorta flour.
In Spain, a seed mixture known as comuña consisting of Lathyrus sativus, L. cicera, Vicia sativa and V. ervilia provides a potent mixture of toxic amino acids to poison monogastric (single stomached) animals. Particularly the toxin beta-cyanoalanine from seeds of V. sativa enhances the toxicity of such a mixture through its inhibition of sulfur amino acid metabolism and hence depletion of protective reduced thiols. Its use for sheep does not pose any lathyrism problems if doses do not exceed 50 percent of the ration.

Famous quotes containing the words modern and/or occurrence:
“A more problematic example is the parallel between the increasingly abstract and insubstantial picture of the physical universe which modern physics has given us and the popularity of abstract and non-representational forms of art and poetry. In each case the representation of reality is increasingly removed from the picture which is immediately presented to us by our senses.”
—Harvey Brooks (b. 1915)
“One is absolutely sickened, not by the crimes that the wicked have committed, but by the punishments that the good have inflicted; and a community is infinitely more brutalised by the habitual employment of punishment than it is by the occasional occurrence of crime.”
—Oscar Wilde (1854–1900)
