On specific gravity.—No. II

On the Group Specific a Substance in Horse Saliva. Ii

A method is described for the purification of the A substance in horse saliva, and additional observations on the chemical properties of the preparation are reported. The preparation isolated was found to be highly active serologically and it appears to be polysaccharide in nature.

Part II: Specific Recommendations for Quality Assurance

Quality assurance in medical services has become a more and more important issue. In order to achieve reliable results of DNA image cytometry as described and discussed in detail in the first part of this report [2], the conditions for reproducible preparation, measurement and interpretation have to be worked out, carefully followed and checked at various steps of the process in certain time in...

On common neighborhood graphs II

Let G be a simple graph with vertex set V (G). The common neighborhood graph or congraph of G, denoted by con(G), is a graph with vertex set V (G), in which two vertices are adjacent if and only if they have at least one common neighbor in G. We compute the congraphs of some composite graphs. Using these results, the congraphs of several special graphs are determined.

Specific association of photosystem II and light-harvesting complex II in partially solubilized photosystem II membranes.

In this study, we report the structural characterization of photosystem II complexes obtained from partially solubilized photosystem II membranes. Direct observation by electron microscopy, within a few minutes after a mild disruption of the membranes with the detergent n-dodecyl-alpha,D-maltoside, revealed the presence of several large supramolecular complexes. Images of these complexes were s...
