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.

The authors present an epizootiological analysis of viral haemorrhagic disease of rabbits in Poland. The biological, physical and chemical properties of virus isolates used for the production and control of the vaccine 'Cunivac' (produced in Poland) are also presented. The safety and efficacy of this vaccine are demonstrated. Laboratory experiments and large-scale field observations yielded sat...

Molecular modeling frequently constructs classification models for the prediction of two-class entities, such as compound bio(in)activity, chemical property (non)existence, protein (non)interaction, and so forth. The models are evaluated using well known metrics such as accuracy or true positive rates. However, these frequently used metrics applied to retrospective and/or artificially generated...
