Cognitive Interviewing to Develop a New Health-Related Quality of Life Measure for Parkinson's Disease: The Preference-Based Parkinson's Disease Index (PB-PDI).

Preference-based measures (PBM) for health-related quality of life (HRQoL) are essential in assessing the cost-utility of different treatment options. The preference-based Parkinson's disease Index (PB-PDI) is being developed for people with Parkinson's disease (PD). The aim of this study was to refine the PB-PDI through cognitive interviews with people with PD.

Biochemical characterization of the respiratory syncytial virus P-P and P-N protein complexes and localization of the P protein oligomerization domain.

The RNA-dependent RNA polymerase complex of respiratory syncytial virus (RSV) is composed of the large polymerase (L), the phosphoprotein (P), the nucleocapsid protein (N) and the co-factors M2-1 and M2-2. The P protein plays a central role within the replicase-transcriptase machinery, forming homo-oligomers and complexes with N and L. In order to study P-P and N-P complexes, and the role of P phosphorylation in these interactions, the human RSV P and N proteins were expressed in E.
