This balance cannot be maintained without a certain degree of reflection on the relationship between different intellectual commitments.
Although cardiac hypertrophy acts as a protective mechanism, it is well understood that this phenotype cannot be maintained long-term.
The model predicted about 95% cycling and 10% quiescent cells killed at each treatment, but this efficacy cannot be maintained after the fourth cycle.
The left forearm and hand seem normal in contour; active abduction of the arm is limited to 90 degrees; with undue effort the hand can be placed on top of the head, but this position cannot be maintained.
Arterial stiffness is lower among individuals who regularly perform aerobic exercise [18], [19], and short-term aerobic exercise training reduces the stiffness in central arteries [19], [20], [21], however this effect cannot be maintained without continued exercise [22].
However, in terrestrial settings without supplementary sources of water, this imbalance cannot be maintained indefinitely, so the mean evaporation from vegetation will not exceed mean rainfall in dryland situations.
The important implication is that this mark cannot be maintained after H3.1/2 has been replaced by H3.3 (due to the inability of ATXR5/6 to methylate H3.3), which could contribute to the opening of a previously inactive chromatin, and be responsible for, for example, the induction of transposable elements.
The finding that talin1-depleted HUVEC can initiate cell spreading on plastic or glass surfaces in the presence of serum is consistent with the report that talin-depleted cells can initiate spreading on fibronectin but that this spreading cannot be maintained in the absence of talin (Zhang et al., 2008).
But this superior performance cannot be maintained indefinitely.
However, after extended periods of alcohol exposure this alternate pathway cannot be maintained.
