In addition, with the recent availability of X-ray structures of several ABC-transporters, also structure-based design methods have been applied and will be addressed.
The World Health Organization (WHO) has developed a basic radiographic system (BRS) designed to overcome these challenges and increase the availability of X-ray services in developing countries [3].
The recent availability of X-ray crystallographic structures of Photosystem II (PSII) together with refined steady-state and time-resolved spectroscopic analyses of site-directed mutants, are leading to a more detailed understanding of the function of this photosystem.
The availability of X-ray crystallography data for both LXRα and β has and will continue to have an important part to play in the structure-based drug design of subtype selective chemotypes, although the difficulty of the challenge should not be underestimated.
The recent availability of X-ray structures for diverse ligand-bound Family A G protein-coupled receptors (GPCRs) in multiple conformations (inactive form with an antagonist/inverse agonist bound and active form with an agonist bound) now enables rational drug design efforts that have historically been applied to soluble enzyme targets.
Additionally the use of hands and feet X-rays for following radiological disease progression is not regular in routine care, especially not at exactly a time interval of 12 month: the fact that the availability of X-rays at two timepoints was an inclusion criteria may have indeed introduced a selection bias into our study.
Despite major progress in our understanding of the human P-gp mechanism, including the availability of X-ray structures of closely related homologues, the molecular details of several aspects of the P-gp reaction cycle remain uncertain.
The availability of the X-ray crystal structure of the dengue virus (DENV) E protein provided an opportunity for in silico drug design efforts to identify candidate inhibitors.
This guideline relies heavily on the acceptance of HIV-testing and availability of chest X-rays.
Spectroscopy and imaging of condensed matter have benefited greatly from the availability of intense X-ray beams from synchrotron sources, both in terms of spatial resolution and of elemental specificity.
In view of the discrepancies among the earlier MD studies, availability of new x-ray and NMR structures, and the continuing disagreement between positions of flanking bases seen in x-ray structures and predicted by NMR, we substantially extend the preceding theoretical studies on RNA kissing complexes.
