When times are hard, the managers say, many more elk die, and the survivors produce fewer offspring -- the population regulates itself.
This was assumed to be so because the presumed endogenous (electromagnetic) signal with which the inducer population regulates its own density trespasses to the inner cuvette, where the tester population adopts its growth decision accordingly, hence indicating that the big inducer population can regulate its density via non-chemical cell-to-cell communication.
The United States, which consumes twenty-five percent of the world's resources with five percent of its population, regulates marketing to children less than any other industrialized democracy.
The properties of the non-ER derived MV1 therefore are consistent with its role as a potentially fusogenic vesicle population regulated by GTP hydrolysis and resulting in heterotypic fusion with other vesicles by localised production of DAG.
Apoptosis or programmed cell death is a physiological process through which cell population regulates normal growth and morphogenesis.
Our data show that the impact of Snail1 activity on the osteoblast population regulates the course of bone cells differentiation and ensures normal bone remodelling.
Within the ARC, there exists two related but exclusive neuronal populations regulating energy balance: the neurons expressing proopiomelanocortin (Pomc) and cocaine- and amphetamine-regulated transcript (Cart), and those expressing neuropeptide Y (Npy) and agouti related peptide (Agrp).
Development of movement models that include the complexities of the external world may allow a better understanding of the neuronal populations regulating these processes, as well as the development of solutions for autonomous vehicles and robots, and neural prostheses for those who are motor impaired.
Intranasal application of VSV induces acute encephalitis characterized by a pronounced myeloid and T cell infiltration with two distinct phagocytic populations regulating VSV encephalitis but not virus clearance [48].
The chemical signature of the ARC populations regulating BAT is controversial, and it seems that more than one neuronal type is taking part in this control.
