Se positions from the anomalous map were used to trace the chains.
From the analysis of Se-Met-ParC55 MAD data sets it was concluded that the relatively large number of Se sites (16 Se sites per monomer, 4 monomers per asymmetric unit) and twinning of the crystals that increased the number of the Se sites in the asymmetric unit to 128, made the determination and refinement of the Se positions very difficult.
After several rounds of model building into both molecules in the asymmetric unit, the NCS operators were refined sufficiently to provide an average map that showed a high level of side chain detail and, together with the Se positions and our high resolution MVt-ΔH1 structure, allowed unambiguous tracing.
Both SHW and CLS played a role in the 2012 JPC-SE position statement on asbestos.
That's exactly as it should be: unless you object to the representation of sexual violence per se (a position that would take some defending), then to represent it as it is is right.
The indicated alleles share a conserved amino acid sequence (QKRAA, QRRAA or RRRAA) – also called the shared epitope (SE) – at position 70 to 74 in the third hypervariable region of the DRβ1 chain.
Therefore, the JPC-SE's position statement calling for the global ban of asbestos (JPC-SE 2012), along with the innumerable epidemiologists who have rapidly risen to support it, is timely and speaks to the injustice being inflicted by mostly high-income countries and their industries against poor and unaware populations in countries where asbestos is heavily used.
In addition, the pulsatile tube became an obstructive zone per se in positions II and III.
Lung recruitment, defined as an opening of previously collapsed lung units, is thus not necessary per se for prone position to improve lung mechanical properties and increase lung gas content.
Figure 3 shows the relationship between the intensity of fluorescent radiation of Cr and Se and the position of the Zn0.81Cd0.20Cr1.99Se4 crystal.
In several cases, modulations were not due to the eye-position signal per se, the apparent eye-position modulation being just an epiphenomenon.
