The traction exerted by a cell on a planar deformable substrate can be indirectly obtained on the basis of the displacement field of the underlying layer. The usual methodology used to address this inverse problem is based on the exploitation of the Green tensor of the linear elasticity problem in a half space (Boussinesq problem), coupled with a minimization algorithm under force penalization....
BACKGROUND Spinal pain syndromes are among the most frequent causes of ill health. Long-lasting sustained overload results in a critical decrease in the distance between neighbouring vertebrae and radiation of pain. The aim of this study was to assess the effect of cervical traction and the TENS method on the strength of painless grip and maximum strength of the arm flexors. MATERIAL AND METH...
BACKGROUND/OBJECTIVES The aim of this study was to determine the most desirable force system to achieve molar protraction from an interdental miniscrew minimizing side-effects. Several iterations of force delivery were simulated through variations in the height of a miniscrew, length of a molar extension arm, and incorporation of a lingual force. MATERIALS/METHODS A three-dimensional mesh mod...
The objective of this study was to measure intradiscal pressure (IDP) changes in the lower cervical spine during a manual cervical distraction (MCD) procedure. Incisions were made anteriorly, and pressure transducers were inserted into each nucleus at lower cervical discs. Four skilled doctors of chiropractic (DCs) performed MCD procedure on nine specimens in prone position with contacts at C5 ...
Background. Elastomeric chains and NiTi coil springs are two major traction aids in orthodontic tooth movements. Force degradation occurs over time in both groups, with higher percentages in elastic chains. The effects of environmental factors and some mouth rinses on this force decay have been previously studied. No study has been performed to evaluate the effect of current popular mouth rinse...
Focal adhesions (FAs) regulate force transfer between the cytoskeleton and ECM-integrin complexes. We previously showed that vinculin regulates force transmission at FAs. Vinculin residence time in FAs correlated with applied force, supporting a mechanosensitive model in which forces stabilize vinculin's active conformation to promote force transfer. In the present study, we examined the relati...
