To date, the pathogenesis of vitiligo is unknown although there are many theories about its etiology, including self-destructive, biochemical, neural, autoimmune, and genetic hypotheses.
Apoptosis is a process of self destruction that requires the activation of a genetic programme that may lead to changes in cell morphology, DNA fragmentation, and protein cross linking.
Factors contributing to the development of vitiligo remain largely unknown. However, a number of hypotheses exist to explain the aetiology: neurochemical-mediated effects on melanocytes, intrinsic melanocyte defect and autoimmunity.

Il semble y avoir une autodestruction de l'implant et la correction reste en général stable; nous n'avons jamais retrouvé ? de maladie du Silastic ? dans ce site.
The present experiments were designed to investigate the influence of amygdala lesions on blood pressure inspontaneously hypertensive rate. The results show that: 1) When compared with control group, the blood pressure was significantly attenuated in the amygdalalesioned SHR;2) The blood pressure after operation was lower than before operation in the amygdala-lesioned SHR; 3)The increase in blood pressure was age-dependent in the control group SHR. These studies indicate that the amygdala complex may play a...
Applying pre-stress to the fiber/adhesive layer is adopted to modify the residual stress of ARALL, and the Bell-peel property influenced by different residual stresses in ARALL is investigated in this paper. The results indicate that the residual stress is lowered by applying prestress and no matter what kind of laminate, as-cured one or prestressed one, the fracture resulting from peeling is multiple. Imposing prestress on ARALL not only contributes to increase the Bell-peel strength, strength, but also c...
