We study inversions of the jump operator on Π1 classes, combined with certain basis theorems. These jump inversions have implications for the study of the jump operator on the random degrees—for various notions of randomness. For example, we characterize the jumps of the weakly 2-random sets which are not 2-random, and the jumps of the weakly 1-random relative to 0′ sets which are not 2-random....

Consistent differences in expression of specific proteins were observed between numerous cancer cell clones with high and low potential for spontaneous metastasis. Seventeen clones from two unrelated murine fibrosarcomas were examined concomitantly for spontaneous formation of lung metastases and for occurrence of individual polypeptide differences by high resolution two-dimensional gel electro...
