Time-resolved in situ SAXS and XAS measurements were carried out to monitor the formation of nanoparticles of the sulfides of cadmium and zinc, from solutions containing he corresponding acetate, and thioacetamide under solvothermal conditions. Analysis of the SAXS data shows that particles of ca 5 nm in radius form within the first few minutes of the reaction and then grow uniformly to ca 20 n...

Cataracts developed in 90% of rainbow trout maintained on a thioacetamide diet for prolonged periods of time. The most striking feature in the histology of these lenses was a massive proliferation of the lens epithelium and its transforma tion to a pleomorphic cell mass which sometimes replaced a great portion of the anterior lens cortex. The profuse invasion of the epithelial cells, their diso...
