• A single-parameter design method that accurately predicts the mechanical properties of octet truss scaffolds was developed. wide-range adjustment Young's modulus and yield strength achieved. The made different polymers with varying d / Ø were mapped. ranges suitable match defferent natural cancellous bones suggested. Designing a scaffold matching to optimize bone regeneration is required in t...

Graft failure is a mortal complication in allogeneic bone marrow transplantation (BMT); T cells and natural killer cells are responsible for graft rejection. However, we have recently demonstrated that the recruitment of donor-derived stromal cells prevents graft failure in allogeneic BMT. This finding prompted us to examine whether a major histocompatibility complex (MHC) restriction exists be...

Abstract Background In this research the biomechanical properties of a bone model was examined. Porcine ribs are used as experimental model. The objective to investigate and compare before after implant placement. Methods samples were divided in three groups, Group 1 where ALL-ON-FOUR protocol during pre-drilling placing implants, 2 pre-drilling, implants not placed, 3 consisting intact bones s...

Euphrates turtle is the only soft shell turtle of Iran, and unfortunately is in danger of extinction due to multiple reasons. Imaging techniques, in addition to their importance in diagnosis of injuries to animals, have been used as non-invasive methods to provide normal anatomic views. A few studies have been conducted to understand body structure of the Euphrates turtle. Since there is only g...
