Tendon the presence of denatured collagen are factors that are believed to cause weakening of the tendon ECM and an increase in the potential for another rupture to occur. In response to repeated mechanical loading or injury, cytokines may be released by tenocytes and can induce the release of MMPs, causing degradation of the ECM and leading to recurring injury and chronic tendinopathies. A variety of other molecules are involved in tendon repair and regeneration. There are five growth factors that have been shown to be significantly upregulated and active during tendon healing: insulin-like growth factor 1 (IGF-I), platelet-derived growth factor
Inelastic mean free path beam has traveled through the solid. The parameter formula_4, termed the inelastic mean free path (IMFP), is defined as the distance an electron beam can travel before its intensity decays to formula_5 of its initial value. The inelastic mean free path of electrons can roughly be described by a universal curve, which is the same for all materials. Inelastic mean free path The inelastic mean free path (IMFP) is an index of how far an electron on average travels through a solid before losing energy. If a monochromatic primary beam of electrons is incident on a solid surface, the majority
