But they are crucial to maintaining regional ecosystems (such as water cycles) and even global ones (for example, carbon sequestration).
And an active withdrawal of atmospheric carbon dioxide will need to be part of managing climate change through, for example, carbon sequestration.
Future fossil fuel power generation is likely to include technologies which increase process efficiency and reduce its impact on the environment, for example, CO2 sequestration.
These potential benefits are difficult to monetise but indeed may be significant depending on project specifics and in the case of, for example, carbon sequestration or coastal defence may provide long term and lasting economic benefits.
For example, when sequestration cuts occurred on March 1 , 2013 I thought to myself, this is going to hurt military people in terms of jobs and pay.
Prototypical example of sequestration as a regulatory mechanism is the accumulation of the ubiquitin ligases MDM2 and the von Hippel-Lindau tumor suppressor protein VHL in the nucleolus (Mekhail et al. 2005, 2007).
If they are regulated, for example, by sequestration rather than degradation or stabilization, no significant changes at the transcript level would occur, and we would not have identified such targets by our microarray studies.
While accumulation of MPP+ in cells is a necessary condition for the toxicity of this molecule, the degree of susceptibility of particular cell types to intracellular MPP+ may vary due to the presence or absence of resistance mechanisms, for example, by sequestration as in adrenomedullary cells (43) or other more poorly understood cellular factors (7, 46).
Empirical studies have shown that the Plasmodium falciparum Erythrocyte Membrane protein 1 (PfEMP1) can mediate cytoadhesion by interacting with various host receptors, resulting for example in sequestration of the infected erythrocytes in the host tissue or rosette formation with uninfected red blood cells [ 13].
