Chinese hamster ovary (CHO) cells cultured in vitro were continuously exposed to increasing concentrations of diethylmaleate (DEM). Chronic exposure of these cells (designated CHO/DEM) to 80 microM diethylmaleate resulted in an increase in cystine transport, a decrease in glutathione inhibition of the enzyme gamma-glutamylcysteine synthetase, elevation of intracellular glutathione levels to 4.3...

This paper presents a procedure for assessing the quality of a digital elevation model (DEM) which has been applied to the output of a normalized cross correlation based stereomatching algorithm. Using semimetric photography of natural gravel river bed surfaces acquired in the field, digital photogrammetry was used to extract DEMs automatically for use in characterizing surface roughness proper...
