Cyclic changes in blood neutrophil counts of grey collie dogs with cyclic hematopoiesis can be eliminated by daily endotoxin injections. Studies were performed to determine the mechanism whereby endotoxin alters this disease. Bone marrow granulocyte-macrophage progenitor cells (colony-forming cells [CFUc]) showed cyclic variation in the untreated grey collie, which was eliminated by chronic end...

The article continues an analysis of the genetic 8-dimensional Yin-Yang-algebra. This algebra was revealed in a course of matrix researches of structures of the genetic code and it was described in the author's articles arXiv:0803.3330 and arXiv:0805.4692. The article presents data about many kinds of cyclic permutations of elements of the genetic code in the genetic (8x8)matrix [C A; U G] of 6...
