    In recent years, many efforts have been made in tissue engineering and new methods for the treatment of cartilage damage, with an emphasis on their non-invasive and less aggressive nature. Meanwhile, injectable and in situ forming hydrogels have been considered as a less invasive nature. On the other hand, lack of enough mechanical properties in these hydrogels is one of their main problem. In this study, gelatin and alginate was used to fabricate hydrogel as interpenetrating network (IPN) hydrogel and silica nano particles were also used to increase mechanical properties in the fabricating of hydrogels. Gelatin is also combined with dopamine in order to induce bio adhesive properties of...

    Coronary artery disease is the first cause of death across the world. Targeted delivery of therapeutics through controlled release of micro- and nano-particles remains a very capable approach to develop new strategies in treating restenosis and atherosclerotic plaques. In this research, to produce the arterial geometry, an image-processing was done using CT-scan images of a LAD coronary artery. After implementing the finite element mesh, the Fluid-Structure Interaction (FSI) simulation based on physiological boundary conditions was performed. Next, a Lagrangian description of particles dynamics in a non-Newtonian blood flow considering momentum equation of motion for each particle and the...
