But if there are two copies of a gene, then the animal has a spare functioning copy, which allows those genes to rack up more mutations — both beneficial, harmful and neutral — without reducing survival fitness).
Therefore, in some instances, mutations in the gene arise that spare functions related to survival, while impairing those that are important for myelination.
A fine balance needs to be reached between successfully eradicating these tumors and the need to spare functioning renal tissue to avoid dialysis.
However, careful linguistically informed experimental designs can reveal the relative autonomy yet cumulative contribution of each component to overall linguistic functioning, and indeed distinctions within components of relatively impaired and spared function (van der Lely and Marshall, 2011).
In any case, the reasonable designs of the lifeline segment are relatively few because of the limits to structure type, function, flux, and coded spare part size.
Also, vasopressin's selective constriction of renal efferent over afferent arterioles could spare renal function in shock.
A range of probe dependencies have been observed for synthetic CCR5 ligands: from compounds that block chemokine binding but not HIV-1 gp-120 binding to compounds that block HIV-1 binding but partially spare CCR5 function through chemokine signaling.
It causes a pins-and-needles sensation in the soles of the foot and legs, but spares motor function and usually does not weaken muscles.
Minimally invasive image-guided ablation techniques and intra-arterial interventions may prolong survival, spare more functioning liver tissue in comparison to surgical resection (which can be very important in cirrhotic patients), allow retreatment if necessary, and may be an effective bridge to transplantation [23, 24, 25, 26, 27].
Most importantly, by using an intersectional approach to restrict DTR expression to the caudal CNS, we were able to spare essential functions such as respiration and chewing.
