Molecular analysis has been done for characterization of the interactions between three beet curly top virus (BCTV) strains and two Arabidopsis ecotypes in terms of virus inducible disease symptoms and infectivities. The total DNA was isolated from three tissues (shoot tips, infection origins and roots) of virus infected plants and this DNA was analyzed by quantitatively and qualitatively to elucidate virus movement and symptom development. CTV-Worland infected Col-O and Sei-O showed only symptom shown in hypersusceptible ecotype Sei-O by BCTV-worland was shoot tip stunting. Kinetics of virus DNA accumulation of three different viruses indicated that roots contained more virus DNA than shoot tips or infection origins, and that disease symptom severity was strongly correlated with virus DNA accumulation. These results suggest that the mild and Worland-specific symptoms shown in Sei-O by BCTV-worland are caused by the interactions of host factors provided by hypersusceptible ecotype and viral factors of mild strain.

This prospective clinical study evaluates the 5-10 year results of the BiPolar shoulder Arthroplasty in patients with end-stage RotatorCuff Arthropathy. The study group consisted of 48 patients (59 shoulders). Average age was 72 years and average FU time was 73 months. Results showed that the average UCLA score went from 7.9 Pre-op to 23.3 Post-op. Final Constant score averaged $52\% (unadjusted). Pain relief using the VAS was 1.2(were 0=no pain. 15 = excruciating pain). ROM improved by an average of $20^\circ$. There were 2 reoperations because of periprosthetic fractures. Despite rather poor functional results, these patients were satisfied with their pain relief and the functional gains accompanying pain relief would be an added benefit.

This is a prospective study in which we evaluate the 5-10 year results of BiPolar shoulder arthroplasty in 64 patients (71 shoulders) with primary glenohumeral osteoarthritis. Fifty two patients (56 shoulders) were followed for greater than 60 months (average 79months)1 and no patients were lost to follow Lip. The average age of the patient at operation was 72.5 years. The UCLA score increased from 10.8 preoperatively to 25,7 postoperatively. The final Constant score in this elderly subset of patients averaged $65\%$ (unadjusted). Eighty seven percent of patients were satisfied with their final result. Excellent pain relief was achieved with a VAS of 2.5 (0=no pain, 15=excruciating pain). Active anterior forward flexion improved from $45^{\circ}$ to $104^{\circ}$. Seventy five percent of patients reveal persisting head-shell motion at an average of 7 years. There were two reoperations because of humeral stem loosening; both stems should have been cemented at the initial arthroplasty. It is demonstrated that BiPolar shoulder arthroplasty is durable over time, with clinical results equivalent to that in the literature when compared with hemiarthroplasty and total shoulder replacement.
