Dinitrosalicylic Acid: a Reagent for the Estimation of Sugar in Normal and Diabetic Urine
The methods used for the quantitative determination of sugar in urine, including the polariscope, ‘give good results when the amount of sugar present is considerable, but there is always a point where the urine contains so little sugar that the results are dubious. Special met)hods have been published for the determination of sugar in normal urine. Many of these give results that are too high, ...
متن کاملThe Determination of Sugar in Blood and Spinal Fluid with Anthrone Reagent*
The anthrone reagent of Dreywood (1) has been applied to the determination of blood sugar by Durham, Bloom, Lewis, and Mandel (2), Fetz and Petrie (3), and Zipf and Waldo (4). In the procedures developed by these authors, the heat resulting from mixing sulfuric acid with water causes the reaction to take place. Greater precision is obtained by heating the mixture of anthrone, sulfuric acid, and...

متن کاملRandom Tree-Puzzle leads to the Yule-Harding distribution.
Approaches to reconstruct phylogenies abound and are widely used in the study of molecular evolution. Partially through extensive simulations, we are beginning to understand the potential pitfalls as well as the advantages of different methods. However, little work has been done on possible biases introduced by the methods if the input data are random and do not carry any phylogenetic signal. A...
