The authors undertook a morphometric study of the intervertebral foramina in anatomic specimens of spines unaffected by degenerative lesions. They studied the variations in shape and size of 38 intervertebral foramina during flexion-extension movements and following an isolated disc collapse. The cast technique takes into account the bony prominences, the(More)
Allosteric regulation at distant sites is central to many cellular processes. In particular, allosteric sites in proteins are major targets to increase the range and selectivity of new drugs, and there is a need for methods capable of identifying intra-molecular signalling pathways leading to allosteric effects. Here, we use an atomistic graph-theoretical(More)
The authors have studied, on anatomical preparations, the variations in shape and size of 38 intervertebral foramina during flexion-extension movements, on spines which were free of degenerative lesions; they also studied the same variations following an isolated disc collapse. The cast technique takes into account the bony prominences, the bulge of the(More)
Using Stochastic Frontier Analysis (SFA) in a sample of commercial banks from 107 countries for the period 1996-2003, we obtain a mean cost efficiency score of 0,84, which supports the evidence found in other works, suggesting an improvement of efficiency scores over the ones obtained in the previous decade. Adding some data on the financial information(More)
In order to investigate the relations between handedness and migraine or immune disorders, we performed a case control study comparing the handedness of patients suffering from systemic lupus erythematosus (SLE), type I diabetes, Graves' disease, or migraine to that of a random sample of controls from the general population. A handedness index was measured(More)
