A structural comparison of the three SpCas9 variants with wild-type SpCas9 revealed that the multiple mutations synergistically induce an unexpected displacement in the phosphodiester backbone of the PAM duplex, thereby allowing the SpCas9 variants to directly recognize the altered PAM nucleotides.
Several hypotheses can be proposed to explain this unexpected phenomenon: a nucleosome displacement induced by histone acetylation could result in masking of critical DNA activation sites (Laribee and Klemsz, 2001), or the gene repression could be linked to the acetylation by TSA of non-histone proteins implicated in gene transcription (Wilson et al, 2002; Mulholland et al, 2003).
However, steel bridges may face large deflections and inelastic displacements due to unexpected live loads and/or unfavorable environmental conditions.
Having new stepbrothers and sisters, uncles and cousins come into the 'work' family can be a lot of fun, but also can be riddled with new and unexpected challenges, turf wars, feelings of displacement and hurt feelings if not integrated and on-boarded right.
The training resulted in reduced trunk displacement and stopping time during unexpected trunk perturbations but did not alter reflex latencies measured with surface electromyography (EMG) in the erector spinae muscles.
Experimental results show that in the grasping reflex, the rate of force is increased four times, and the sliding displacement of the grasped object subjected to unexpected disturbances is reduced from 10 mm to 5.7 mm.
We have noted many technical challenges with the administration of aerosolized epoprostenol (such as cannula displacement and interruptions in the delivery system) leading to unexpected hemodynamic decompensation [ 10, 11].
However, the deck displacement becomes excessively large when subjected to ground motion with unexpected characteristics.
Based on the current recorded experimental data, several aspects are addressed in the paper, including the observed THM behavior of the compacted bentonite, the displacement of the electrical heater, and also the influence of unexpected interruptions of electric power supply.
With those words, he summed up the feeling of displacement and angry bewilderment that many felt when faced with the unexpected result.
