Some computational models at the cellular level.
A number of viewpoints on how a cell can be modelled are discussed in this paper in light of the ability it has to process information. The paper begins with a very brief summary of four general types of computation: sequential, parallel, distributed, and emergent. These form the general framework from which a number of comparisons are made. Several metaphors are introduced to enable reflection...
متن کاملMetabolism of the myocardium at cellular level.
The contractile properties of the heart are the result of the interaction of a complex system of intracellular filaments (Gergely, 1966). These lie longitudinally in the cell and consist of alternating arrays of thick and thin filaments. The thin filaments arise from each side of transversely oriented Z lines and interdigitate with the thick filaments forming a structure which repeats along the...
متن کاملCellular identity at the single-cell level.
A single cell creates surprising heterogeneity in a multicellular organism. While every organismal cell shares almost an identical genome, molecular interactions in cells alter the use of DNA sequences to modulate the gene of interest for specialization of cellular functions. Each cell gains a unique identity through molecular coding across the DNA, RNA, and protein conversions. On the other ha...
متن کاملAntibody Synthesis at the Cellular Level
The specific suppressing activity of passively administered antibody on 7S antibody synthesis against sheep and chicken red blood cells has been investigated at the cellular level using the indirect hemolytic agar-plaque technique. 7S antibody production was found to be sensitive to antibody-induced suppression. No inhibitory effect of transferred antibody was seen until 48 to 72 hr after admin...
متن کامل“Persisters”: Survival at the Cellular Level
Rather than being slowly eroded and destroyed, countless numbers of varied forms of life adapt to the diverse aspects of an ever changing environment. However, the amount of variation is maintained at a practical optimum, as too much variation would make the population ill-adapted in a stable environment, while too little variation would render it unable to adapt to environmental stresses. This...
