We review our results of transplantation performed during the last 10 years in 65 children less than 15 years old: 32 parental grafts (group P) are compared with 35 grafts from well-matched (mean HLA-A,B mismatches: 1.7) cadavers (group C). Group P patients' survival is slightly but not significantly better than that o…

OBJECTIVE: To evaluate the effectiveness of pedicle subtraction osteotomy (PSO) assisted with anterior column reconstruction in the treatment of chronic osteoporotic vertebral compression fracture (OVCF).

We have used Landsat-5 TM and Landsat-7 ETM+ images together with simultaneous ground-truth data at sample points in the Doñana marshes to predict water turbidity and depth from band reflectance using Generalized Additive Models. We have point samples for 12 different dates simultaneous with 7 Landsat-5 and 5 Land…

This study reports a follow-up on 2415 occlusal sealings performed in a dental office. After nine to ten years service time, the survival rate of all sealed surfaces dropped to 69.5% because of either occlusal or interproximal carious activities. Retention of the sealings was intact in 91.5% after one year, but dropped…
