Knotless anchors are widely used nowadays for shoulder instability repair, providing a fast and secure way of labral fixation with favorable long-term outcomes.
Although nitrogen and phosphorus are both necessary for the growth of algae, phosphorus input is more critical as many cyanobacteria are able to provide their nitrogen requirement from the available atmospheric nitrogen by way of nitrogen fixation (Kortstee et al., 1994).
The C-terminal biotinylation of a protein can be a superior way of protein fixation on streptavidin-coated surfaces including protein microchips used in proteomics.
Coating of components with trabecular metal (TM) is a new way of enhancing fixation to bone.
The time point of application as well as the way of implant fixation (press fit) seem to be decisive for the effect of BP in osseointegration.
Hence, an incompatibility is present, which has prompted an ongoing discussion in the recent literature on the best way of stem fixation (Nelson et al. 2003, Mabry and Hanssen 2007, Wood et al. 2009).
If these populations are on the way to fixation of AM, the relative stability of populations over generations suggests that this process is moving slowly.
In the two-locus Dobzhansky-Muller model of hybrid incompatibility, the heterozygote genotype AaBB is a necessary step on the way to fixation of the genotype aaBB in one of the diverging populations.
The altitudinal, latitudinal, and radial variation in AM frequencies could be interpreted as either populations at a polygenic equilibrium or transient states on the way to fixation of AM.
While one appears on its way to fixation, the ascent of the other is compromised as the likely underlying MRC2 mutation causes crooked tail syndrome in homozygotes.
