Unintended Consequences of Data Sharing Under the Meaningful Use Program.

Interoperability has been designed to improve the quality and efficiency of health care. It allows the Centers for Medicare and Medicaid Services to collect data on quality measures as a part of the Meaningful Use program. Covered providers who fail to provide data have lower rates of reimbursement.

Orientation of d-tubocurarine in the muscle nicotinic acetylcholine receptor-binding site.

Ligand modification and receptor site-directed mutagenesis were used to examine binding of the competitive antagonist, d-tubocurarine (dTC), to the muscle-type nicotinic acetylcholine receptor (AChR). By using various dTC analogs, we measured the interactions of specific dTC functional groups with amino acid positions in the AChR gamma-subunit. Because data for mutations at residue gammaTyr(117) were the most consistent with direct interaction with dTC, we focused on that residue.
