Cataphoresis of Chinese Ink in Water Containing Deuterium Oxide

Carboxypeptidasey from Saccharomyces cerevisiae Conformational Difference Reflected in Kinetic Behaviour in Water and Deuterium Oxide

Aqueous Solutions of Deuterium Oxide

The differences between the boiling points of dilute aqueous solutions of heavy water and the boiling point of ordinary water were measured in the range from 0.3 to 7 percent of D 20. The boiling points were found to increase linearly with increase in D 20, according to the equation mole % of D20 = 70.9 (tJ.T), where tJ.T is the boiling point in degrees centigrade minus 100. The measmements, ma...

Studies of Body Water and Water Turnover Determined with Deuterium Oxide Added to Food.

In 5 dogs which ingested 25 or 50 ml. of D20 with one daily meal, maximal plasma concentrations of tracer were reached in 12-24 hr. The disappearance rate during 14 days was exponential, confirming studies of others in humans. Water turnover, calculated from values obtained for body water and the disappearance rates, agreed well with total water intake, which included water taken as such and th...

Derangement of microtubule arrays in interphase and mitotic PtK2 cells treated with deuterium oxide (heavy water).

The extent and pattern of the rearrangements of microtubule arrays in interphase and mitotic PtK2 cells treated with deuterium oxide (2H2O) were evaluated using light, immunofluorescence and electron microscopy. Combined labelling with anti-tubulin antibodies and staining with a DNA-specific fluorochrome revealed that 2H2O influences the reassembly of the cytoplasmic microtubule complex (CMTC) ...
