It is shown how one can understand the frequencies of occurrence of nucleotides in coding DNA sequences on the basis of electron-ion interaction potential.
The pseudopotential with respect to free electrons has been calculated for a series of chemical substances. These potentials are different for carcinogenic, mutagenic-carcinogenic, and mutagenic substances thus allowing the theoretical prediction of their biological activity. The reaction mechanism is discussed on the basis of the interaction potential.
The hippocampal formation is а part of the limbic system located in the medial temporal lobe and consists of the three layered archicortex, mostly pyramidal cells. Hippocampal formation encompasses dentate gyrus, hippocampus proper and subiculum, and possibly presubiculum, parasubiculum and entorhinal cortex. It receives inputs from primary and secondary… (More)
A correlation between the carcinogenicity of organic substances and their UV-absorption characteristics has been established. It is found that chemical carcinogens have absorption maxima in the wavelength region of 206--248 nm. On the basis of revealed correlation, a mechanism of chemical carcinogenesis is proposed.
The relatedness of phonological coding to the articulatory mechanisms in visual word recognition vary in different writing systems. While articulatory suppression (i.e., continuous verbalising during a visual word processing task) has a detrimental effect on the processing of Japanese words printed in regular syllabic Khana script, it has no such effect on… (More)
