Earlier studies (Soonpaa et al., 1996) revealed a rapid drop-off of ventricular cardiomyocyte cell-cycle activity at birth in mice, followed by a burst of DNA synthesis during the first week of postnatal life which contributed to the formation of multi-nucleated cardiomyocytes by postnatal day 10 (PN10). It has recently been suggested that a second burst of cardiomyocyte cell-cycle activity occ...
This paper analyzes a model in which the risk associated with entrepreneurial activity implies that the amount of such activity is procyclical and results in both amplification and intertemporal propagation of productivity shocks. In the model risk averse agents choose between a riskless project and a risky project with higher expected return (‘the entrepreneurial activity’). Agents who choose ...
Previous papers from this laboratory (King and Cheldelin, 1952, 1952a, 1954; Hauge et al., 1955, 1955a) have reported on the oxidation of carbohydrates in Acetobacter suboxydans. Neither resting nor disintegrated cells can oxidize acetate or other intermediates of the tricarboxylic acid cycle. These findings have recently been confirmed in another laboratory (Rao and Gunsalus, 1955). From the c...
