TLDR
The sensitivity of the colorimetric reaction and stability of the colour are enhanced over existing related procedures and the serum blank diminished, enabling urea to be precisely measured in micro amounts (1--5 microliters) of serum.About:

The interactive effects of feeding and exercise on oxygen consumption, swimming performance and protein usage in juvenile rainbow trout (Oncorhynchus mykiss)
Derek Alsop,Chris M. Wood +1 more
TL;DR: The results suggest that the irreducible SDA load reduces swimming performance and that O2max is limited by the capacity to take up O2 at the gills and/or to deliver O2 through the circulatory system rather than by thecapacity to consume O2at the tissues.

TL;DR: It is reported that apoptosis could be induced in TGase2-/- mice; however, the clearance of apoptotic cells was defective during the involution of thymus elicited by dexamethasone, anti-CD3 antibody, or γ-irradiation, and in the liver after induced hyperplasia.

Comparison of methods for the analysis of dissolved urea in seawater
Neil M. Price,Paul Harrison +1 more
TL;DR: The diacetyl monoxime method was suitable for urea determinations in all the seawater samples examined; it was easily automated, and the results were accurate and reproducible, and this modified technique is recommended for measuring disolved concentrations of urea in seawater.

A New Simple Semimicro Method for Colorimetric Determination of Urea
J. J. Coulombe,L. Favreau +1 more
TL;DR: A new simple and rapid method for quantitative semimicro determination of blood urea is presented, with a maximum adsorption at 530 mµ stable at room temperature and requiring 0.2 ml.

The carbamido diacetyl reaction: a test for citrulline
TL;DR: An approach to the study of problems regarding the distribution of citrulline in natural proteins, the origin and significance of carbamido-acids, and the nature of the mechanism involving the elaboration of citrile from its precursors, ornithine, ammonia and carbon dioxide, and its subsequent conversion into arginine is begun.

A spectrophotometric method for determination of urea
G. Ceriotti,L. Spandrio +1 more
TL;DR: If phenazone is substituted for perchloric acid or arsenic pentoxide in the diacetylmonoxime reaction for urea determination, a colored product is formed, apparently from a double condensation of Phenazone with diacetymoxime and urea, and Beer's law is followed.
