Synovial Fibrosis in Osteoarthritis of the Knee: Mechanism of Development and Potential Therapeutic Targets
<p>Synovial tissue fibrosis is an immune mediated disease characterized by fibroblast cell migration, proliferation and transition to a myofibroblast phenotype characterized by alpha smooth muscle actin (a-SMA) upregulation and stress fiber formation. Transforming growth factor-β (TGF-b) plays an …

Design of low-cost, fully passive prosthetic knee for persons with transfemoral amputation in India
An estimated 230,000 above-knee amputees are in need of prosthetic devices in India with a majority of them facing severe socio-economic constraints in their daily lives. However, only a few passive prosthetic knee devices in the market have been designed to enable normative gait and to meet the …

Integrated Prosthetic Leg Design Frameworks for People with an Above-Knee Amputation
… low-cost, high biomechanical performance above-knee prosthetic leg components (prosthetic foot and knee) that will result in a walking motion likely to be perceived as able-bodied after minimal acclimation time. Above-knee amputees have two common gait deviations from able-bodied and below-knee …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
… and reduce cost is to use ortho-planar compliant mechanisms which can be made from sheets of material, or lamina emergent mechanisms (LEMs). This thesis presents principles which can be used for designing LEMs. Pop-up paper mechanisms use topologies similar to LEMs, so it is advantageous to study …
