Fluorescent-labeled antibodies: Balancing functionality and degree of labeling

S Vira, E Mekhedov, G Humphrey, PS Blank - Analytical biochemistry, 2010 - Elsevier
A critical assumption in using labeled antibodies is that the conjugation reaction has no
deleterious effects on antibody avidity. This study demonstrates that this assumption need not …

Does vertebral level of pedicle subtraction osteotomy correlate with degree of spinopelvic parameter correction?

V Lafage, F Schwab, S Vira, R Hart, D Burton… - … of Neurosurgery: Spine, 2011 - thejns.org
Object Pedicle subtraction osteotomy (PSO) is a spinal realignment technique that may be
used to correct sagittal spinal imbalance. Theoretically, the level and degree of resection via a …

Role of pelvic translation and lower-extremity compensation to maintain gravity line position in spinal deformity

…, V Challier, R Lafage, BG Diebo, S Vira… - … of Neurosurgery: Spine, 2016 - thejns.org
