Influenza virus polymerase uses capped RNA primers for transcription initiation in infected cells. This unique mechanism involves the specific binding of the polymerase to capped mRNA precursors in the nucleus of infected cells. These host RNAs are then cleaved by a polymerase associated endonuclease at a position 10-15 nucleotides downstream of the cap(More)
The influenza virus polymerase complex contains two associated enzymatic activities, an endoribonuclease and a RNA-dependent RNA polymerase activity. Both activities have so far been observed only with the complete polymerase complex consisting of three subunits, PB1, PB2, and PA. This chapter describes a robust and optimized procedure for the purification(More)
This article identifies and critically appraises six systematic reviews published from 2007 to 2013 that assessed the efficacy of interventions used by occupational therapists for adults with rheumatoid arthritis. Results suggest there is sufficient evidence to support the use of therapeutic exercise, patient education through joint protection, and(More)
We describe a fast and robust new assay format to measure poly(A) polymerase (PAP) activity in a microtiter plate format. The new assay principle uses only natural nucleotide triphosphates and avoids a labour-intensive filtration step. A coupled enzymatic system combining PAP and reverse transcriptase forms the basis of the assay. The PAP generates a(More)
Immobilization of the globe by tenotomization of the extrinsic muscles of one eye reduces the encounter rate for X-latency cells in the contralateral dorsal lateral geniculate nucleus (LGN) of adult cats. The reduction in the relative encounter rate for X-latency cells after tenotomy was comparable to that previously observed in the adult cat following(More)
