Full textThere are many sports-related knee injuries, some of which involve the iliotibial band (ITT). This is a thicker part of the deep fascia of the thigh, called fascia lata. The fascia lata is a fibrous connective tissue composed of elastin fibers and networks of collagen fibers present in different layers of tissue. It has a stabilizing role in the joint and allows the transfer of forces between muscles, but its properties and strain mechanisms remain poorly understood. In this context, the strain mechanisms of the fascia lata during physiological knee movements were studied. Quantitative data of fascia lata strain fields were obtained in situ highlighting strain mechanisms in tension, compression, and shear. Therefore, the mechanical behavior of isolated fascia lata samples was analyzed with shear tests such as bias extension tests and traction of a large band tissue. The study of collagen fiber kinematics was also included. A first contribution to the finite element modelling of fascia behavior was also proposed. Finally, as the natural state of deformation of the fascia lata contributes to good knee mobility, an in situ study was set up to evaluate the impact on joint mobility and strain levels on fascia of a surgical tension-release technique, known as pie-crusting, applied to the ITT and which may be recommended in pathological cases. All the work carried out therefore provides new elements in the study of the mechanical behavior of fascia lata

Full textFocusing on planar and fibrous soft tissues, this work has consisted in determining both the mechanical properties and the failure characteristics of the human skin, in loading conditions close to an impact. In the experimental study, the results have pointed out the relationship between some micro structural parameters of the tissue and the mechanical properties measured at the macroscopic scale. According to this micro/macro dependency, a constitutive law, including structural parameters related to the fibres, has been implemented in a finite element model. The main advantage of such a model is to more locally simulate the tissue behaviour and its failure. The experiments on the human skin bring original and more precise data than classical studies. On the one hand, a heterogeneous strain field has clearly appeared and its heterogeneity has been quantified thanks to a full field measurement technique adapted to the skin. On the other hand, at the microscopic scale, the collagen fibre orientations have been determined and linked to different rupture mechanisms. The first simulations on the human skin have pointed out the importance of using a structural constitutive law in order to model complex physical phenomenon (heterogeneous strain field, gradual rupture of the tissue). Being easily suitable for any planar and fibrous soft tissues, both the testing methodology and the finite element model present interesting perspectives for tissues that are severely injured in automotive collisions. Then, considering individual diversity, such a structural approach will enable to personalize models as structural parameters are everyone's identity

Full textPrevious work in our laboratory has shown that the amino acid histidine can be used a ligand for the purification of human immunoglobulin subclasses and monoclonal antibodies. Ln this work, we tried to combine the specificity of the ligand histidine with hollow fiber membrane technology to create a powerful device for the separation of IgG for human serum and for other sources. We chose poly( ethylene vinyl alcohol) (PEVA) hollow fibber membranes as the support material. The best IgG adsorption was obtained in presence of the zwitterionic buffers. By choosing the appropriate buffer system, it was possible to adsorb on membrane specifically different IgG subsets. For instance, in Mops buffer, IgG1, IgG2 and IgG3 were bound, whereas in Tris-HC1, only IgG3 and a part of the IgG1 fraction were retained. The parameters involved in the optimization of the separation process, namely the influence of residence time and serum and plasma dilution on immunoglobulin adsorption were studied in view of two applications: purification of IgG and removal of IgG from plasma in clinical aphaeresis (extracorporeal device). The capacity of Histidyl-PEVA calculated on the basis of unit membrane volume was 86 mg IgG/ml. Ln comparation of the protein A-membrane reported in literature, the capacity of Histidyl-PEVA was found to be 3 to 8 fold higher
