Micronucleation in the lens epithelium following in vivo exposure to physical and chemical mutagens
Rats were exposed to cataractogenic doses of known physical and chemical genotoxic agents in order to study the efficacy of using micronuclei to monitor mutagenicity in the lens epithelium. The total numbers of micronuclei were counted in lens epithelia from rats exposed to graded doses of either 250 kVp X-rays or the anti-leukemic drug, 1,4 dimethanesulfonoxybutane (Myleran (R)). The results indicate a dose-dependent incidence of micronucleation in the lens epithelium following exposure. The findings are consistent with the hypothesis that the cataractogenicity of certain agents may be related to their effect on the genome of lens epithelial cells.

Electrolytes for Low Temperature Lithium Batteries Based on Ternary Mixtures of Aliphatic Carbonates
The success of rechargeable lithium ion batteries may be largely attributed to the surface films on the carbon anodes, which provide the anodes with adequate protection against continued reaction with electrolyte while permitting charge transfer.
