Extracellular Signaling in an Oscillatory Yeast Culture,ry metabolism in a population. The synchronized metabolic oscillation was dependent on the aeration rate, high aeration stopped the oscillation suggesting that synchronization was caused by a volatile compound in the culture. Ethanol, acetate, acetaldehyde and oxygen were found not to be the synchro

Involvement of Receptor-Kinase in the Biochemistry Upstream from cAMP Synthesis in Cells,cond” messenger agent cAMP drives pleiotypic cascades inherent in the networks of cellular signal processing. The range of phenomena dependent on cAMP includes neuromodulation, glycogenolysis and gluconeogenesis, and cardiac contraction. Any of these examples serves to illustrate that defects in cAM

The secretory pattern of LH changes throughout the reproductive cycle (the menstrual cycle in women, the oestrous cycle in other female mammals). In all female mammals, a large preovulatory surge in the release of LH is the main trigger for ovulation to occur; at other times LH is

Computation and Information an Introduction to Section 2,sms falls obviously into the category of self-organising processes it requires an essentially non linear feedback between its dynamic components. It is suggested that this feedback can be based upon interaction between passive (imposed from outside) and active (generated within a system itself) mech

Morphomechanical Feedback in Embryonic Development,ion (e.g., Prigogine, 1980). The developing organisms may be definitely attributed to self-organizing entities by a number of criteria and, above all, by their capacity for spontaneous breaks of the symmetry order. We define those breaks of macroscopical symmetry as spontaneous which do not imply an
