One basic fact we want to point out is that editing allows a higher GC content in the genome, because forward editing permits fixation of C in the sense strand and G in the antisense strand, and genes in organellar genomes are distributed on both strands of a circular molecule.
This would also permit the fixation of this Central allele at the Western edge of the contact zone by repetitive backcrosses, consistent with the observed pattern.
The haptic design of the single-piece AcrySof® (Alcon) IOL permitted secure fixation of the suture to the haptic.
Their microoxic interior permits N2 fixation by nitrogenase, a highly O2-sensitive enzyme.
Results of this in vitro study indicate that a modified hemispherical implant geometry can reduce head center elevation while permitting favorable screw fixation trajectories into the pelvis in comparison to a conventional jumbo cup.
In both experiments CO2 levels were allowed to range widely from a few hundred to about 3000 ppm, which permitted observation of fixation rates both at varying CO2 concentrations and at each number of days after planting.
Screw fixation permits a lesser degree of soft-tissue handling and dissection compared with plate-and-screw fixation.
Spanning fixation permits repeated, unobstructed and comfortable inspection of the soft tissue status prior to definitive surgery.
External fixation permits minimal disruption of the precarious biology remaining in this area, and circular external fixation not only permits post-operative alterations in alignment and contact between fracture fragments (a commonly quoted advantage of external fixation in general) but more importantly controls the biomechanical environment.
Rigid internal fixation permits early exercises, and good or excellent functional recovery of the elbow was achieved in all patients in this case series.
Previous attempts to investigate HSC proliferation history have been limited to assays that involve in vitro manipulation of donor cell populations for efficient labeling, or that require fixation to permit experimental readout [2], [3], [5], [8], [22].
