The Ultimate Units in Protein Solutions and the Changes Which Accompany the Process of Solution of Proteins

1. The experiments show that suspensions of finely divided particles of insoluble proteins incapable of swelling in acid (denatured egg albumin, casein trichloroacetate, sulfate, etc.) raise the viscosity of the suspension but little and that the influence of acid on the viscosity is negligible. 2. The same is true for solutions of certain genuine proteins such as genuine crystalline egg albumi...

The Ultimate Units in Protein Solutions and the Changes Which Accompany the Process of Solution of Proteins. by Jacques Loeb and 1vl Kunitz

A number of facts suggest that the genuine proteins are kept in aqueous solution by the forces of attraction between the molecules of proteins or their polar groups and the molecules of water, or, in other words, that they form true solutions. Such facts are the high concentrations of salts required for precipitation of genuine proteins (regardless of valency of ion), the increase in solubility...

Do Cognitive Changes Accompany Developments in the Adolescent Brain?

The news that the brain continues to develop through much of adolescence risks becoming an explanation for anything and everything about teenagers and suggests the need for closer analysis. Central to such analysis is clarifying what develops at a psychological level during these years. An examination of contemporary research data on adolescent cognitive development identifies increased executi...

Electrophysiological changes that accompany reactive gliosis in vitro.

An in vitro injury model was used to examine the electrophysiological changes that accompany reactive gliosis. Mechanical scarring of confluent spinal cord astrocytes led to a threefold increase in the proliferation of scar-associated astrocytes, as judged by bromodeoxyuridine (BrdU) labeling. Whole-cell patch-clamp recordings demonstrated that current profiles differed absolutely between nonpr...
