Mosaic mutations induced in Drosophila by ethylenimine.

irst well defined case of the mutagenic effectiveness of chemicals was Tyet:ied for mustard gas treatment of Drosophila by AUERBACH and ROBSON ( 1946). Chemical mutagenesis studies have since been extended to a number of biological systems, including bacteria, fungi and higher organisms. AUERBACH (1965) has discussed the development of chemical mutagenesis in the last 20 years. The application ...

CH2-Symmetric/CH2-Antisymmetric Stretch Ratio Sensor for Cell Analysis

Here we report on a novel infrared sensor system for measuring the CH2-symmetric/CH2-antisymmetric stretch ratio of cell samples. Based on IR absorbance spectra of healthy and malignant breast [1], blood [2] and brain [3] cells found in literature we hypothesized the possibility of disease stage cell discrimination by only comparing a few absorbance peaks in the lipid absorbance wavelength regi...
