TL;DR: It has been gencrally assumed that the inhibition of cholinesterase by physostigmine and prostigmine is non-competitive, but as Lineweaver and Burk have made clear, the type of inhibition cannot be determined from this relationship.

TL;DR: Presented in this communication are procedures for the simultaneous determination of serum inorganic phosphate and ‘(acid” and “alkaline” phosphatase activity.

TL;DR: The presence, in appreciable and measurable concentration, of material that is presumably creatine has been established by an adaptation of the Folin and Wu calorimetric technique to the Evelyn-Malloy photoelectric calorimeter.

TL;DR: The present investigation deals with the preparation and some of the characteristics of purified potato phosphorylase.

TL;DR: In this paper, the authors investigated the kinetics of the reaction between ammonium and cyanate ions and concluded that the reaction is a mixture of ionic strength on the velocity.

TL;DR: The conclusions derived from kinetic studies undertaken by numerous investigators have been in agreement; namely, that desoxyribosenucleic acid polymerizes polydispersely in solution to form heavy asymmetric particles.

TL;DR: The ratio of lactic to pyruvic acid in the blood is suggested as a measure of oxidative conditions in tissues, and it is applied to various studies now in progress dealing with muscular exercise and the reaction of human subjects to high altitude.

TL;DR: This paper confirms and extends the work of Eakin and his associates on preparing highly active concentrates from raw egg white which combine atoichiometrically with biotin and render it unavailable to yeast, and refers to the substance as an antibiotin factor.

TL;DR: It seems evident, therefore, that normal pigmented tissues do not provide a rich enough source for any detailed study of this enzyme system, and the melanoma, a tumor composed chiefly of melanin-producing cells, might be expected to provide a richer source of the enzyme.

TL;DR: An investigation of the blood proteins in tuberculosis by this newer method, using the Tiselius electrophoresis apparatus, found a decrease in the albumin to globulin ratio and new components arc readily detected.
