[EX Q]: We performed experiments to determine the effect of PKR activation on respiratory syncytial virus (RSV) replication. We first determined that RSV infection activates PKR which induces the phosphorylation of eIF2α, resulting in the formation of host stress granules. We used RNA interference to decrease endogenous PKR levels. RSV replication was not altered in cells deficient for PKR expression. However, RSV-mediated stress granule formation was significantly reduced in PKR-knockdown cells. As an alternative method to block PKR activation, we used treatment with the kinase inhibitor 2-aminopurine (2-AP). We observed that 2-AP treatment significantly reduced viral replication. We also treated PKR-knockdown cells with 2-AP and inoculated with RSV. Under these conditions, 2-AP treatment diminished viral replication in the absence of PKR expression. These results suggest that PKR activation has a minimal effect on RSV replication and that the antiviral effect of 2-AP during RSV infection likely occurs via a PKR-independent mechanism.
[EX A]: Activation of protein kinase R is required for induction of stress granules by respiratory syncytial virus but dispensable for viral replication

[EX Q]: Background: A novel strain of influenza A (H1N1) was identified in April 2009 and developed into a pandemic by June 2009. This rapid and unexpected event had enormous implications for infection preventionists (IP) internationally. Lessons learned from this event should guide future pandemic planning efforts. Methods: Focus groups were conducted at the Association for Professionals in Infection Control and Epidemiology, Inc, (APIC) 2009 conference to evaluate IPs' experience with the novel H1N1 influenza pandemic and assess their perceived needs related to novel H1N1 topics and products required for future education and reference materials. Results: Forty IPs (37 from the United States and 3 international) participated in the focus groups. Needed reference materials identified by attendees included infection prevention guidance for nonacute care settings; occupational health polices; and brief, multilanguage patient/family educational materials. Educational topics on which IPs need to be trained include isolation precautions/ personal protective equipment recommendations for novel H1N1 patients, coordination between hospitals and community response agencies, and surge management. The rapidly changing and conflicting recommendations related to patient management made responding to this event challenging. IPs require synthesized infection prevention guidelines developed in a concise, real-time format. Conclusion: IPs must continue to partner with public health and other response agencies to address gaps in pandemic planning.

[EX Q]: Membrane-spanning α-helices represent major sites of protein-protein interaction in membrane protein oligomerization and folding. As such, these interactions may be of exquisite specifi city. Specifi city oft en rests on a complex interplay of diff erent types of residues forming the helix-helix interfaces via dense packing and diff erent non-covalent forces, including van der Waal's forces, hydrogen bonding, charge-charge interactions, and aromatic interactions. Th ese interfaces oft en contain complex residue motifs where the contribution of constituent amino acids depends on the context of the surrounding sequence. Moreover, transmembrane helix-helix interactions are increasingly recognized as being dynamic and dependent on the functional state of a given protein. Abbreviations: GpA, glycophorin A; H-bond, hydrogen bond; TMD, transmembrane domain.
