TL;DR: In the course of a comparative study of several methods for the determination of sugar in blood, it became desirable to investigate the reaction betsveen copper sulfate and potassium iodide which is concerned in a number of methods.

TL;DR: In this article, it was shown that the most suitable reagent would be a compound similar to picric acid in that it, would be reduced by glucose to form a highly colored nitroamino compound, but dissimilar to Picric acid, it would neither form colored compounds with acetone or creatinine nor be reduced in the presence of urinary constituents other than the sugars.

TL;DR: With improvements in technique, and a growing appreciation of the inherent difficulties in the estimation of ammonia in blood there has been a preponderant trend to the lower extreme of values, until, according to Myers (3), ‘(there appears to be some question at the present time as to whether ammonia actually exists in the blood).

TL;DR: In this paper, the Volhard method was applied to the determination of chlorides in protein-free filtrates by the use of tungstic acid, as developed and used by Folin.

TL;DR: A method by means of which the concentration of all these elements may be quantitatively determined on 7 cc.

TL;DR: The first recognition of the role of the lactic acid bacteria in the fermentation of pentoses was in 1894 when Kayser (1) isolated from sauerkraut an organism which fermented arabinose and xylose with the production of Lactic acid as discussed by the authors.

TL;DR: The investigation embodied in this paper was primarily under-taken in an endeavor to determine in what manner H&3 is ‘transported in the blood after inhalation of this gas’.

TL;DR: In 1919 Haggard and Henderson outlined a method for the direct determination of the carbon dioxide tension of arterial and venous blood and demonstrated the applicability of the method to the study of abnormal physiological conditions involving disturbances of the respiratory system and the acidbase equilibrium in the blood.
