Dear Editors: In an earlier paper by Linus Pauling titled "Genetic and Somatic Effects of Carbon-14" (1), it is established that this by-product of nuclear explosions might induce greater genetic and somatic damage than previously assumed. Furthermore, Pauling states that the damage produced by carbon-14 that is incorporated into genetic material is… (More)
A neural circuit at the human cerebellar cortex and nuclei is interpreted in terms of an optimized code and a reliable network.
Murine and human melanoma cells differ relatively reliably from non-tumorigenic melanocytes in certain biological properties. When cultured at low pH, melanocytes tend to be pigmented and melanoma cells unpigmented. The growth of virtually all metastatic melanoma cells is inhibited by phorbol esters such as TPA (12-0-tetradecanoyl phorbol-13-acetate), which… (More)
The transcription-translation process is represented by a virtual neural network. The input unit corresponds to the transcription process, the hidden unit to the mRNA-ribosome-tRNA interaction and the output unit to the final state of the protein. A correlation was found between the natural amino acid frequency and the degree of codon degeneracy and an… (More)
