PURPOSE To examine the distribution of acetylated alpha-tubulin in the connecting cilium of rat rod photoreceptors during different stages of photoreceptor development. METHODS An antibody found to be specific for the acetylated form of alpha-tubulin was used in immunoelectron microscopy of retinas from animals of different ages. RESULTS All the microtubules of the connecting cilium, includ...
The natural stiffness of DNA, which contributes to the interactions of the many proteins involved in its biological processing and packaging, also plays an important role in modern nanotechnology. Here we report new Monte-Carlo simulations of deformable DNA molecules of potential utility in understanding the behavior of the long, double-helical polymer in the tight confines of a cell and in the...
BACKGROUND Pseudoarthrosis after pedicle subtraction osteotomy (PSO) can require revision surgery due to posterior rod failure, and the stiffness of these revision constructs has not been quantified. OBJECTIVE To compare the multidirectional bending stiffness of 7 revision strategies following rod failure. METHODS Seven fresh-frozen human spines (T11-pelvis) were tested as follows: (1) post...
