A novel device is described for efficiently harvesting bone marrow in bone marrow transplantation that uses a newly developed passive flexible drilling unit and suction mechanism. The device reduces the invasiveness of bone marrow harvesting by collecting stem cells from the iliac bone with minimal punctures and by reducing the operation time and the contamination by T cells. The device is inse...

Enzymatic grafting of synthetic molecules onto lignins provides a mild and eco-friendly alternative for the functionalization of lignocellulosic materials. In this study, laccase-mediated grafting of octadecylamine (OA) onto lignin-rich jute fabrics was investigated for enhancing the surface hydrophobicity. First, the lignins in jute fabrics were isolated and analyzed in the macromolecular leve...

vegetative propagation of persian walnut encounters a major problem in iran growing conditions. this experiment was carried out to study the physiological effects of rootstock as regards herbaceousness or woodiness, and with respect to the presence of leaf on it or not on minigrafting success. throughout the study, 1.5-2.5 cm length persian walnut scions were minigrafted on herbaceous vs. softw...

OBJECTIVE Fat grafting is used to improve the reconstructed breast. Local recurrences following mastectomy present as palpable subcutaneous nodules; fat necrosis/oil cysts, a sequelae of fat grafting, also present as subcutaneous nodules. Our objective was to examine the frequency and factors associated with fat necrosis in the postmastectomy reconstructed breast and propose an algorithm for ma...

BACKGROUND Aesthetic skeletal surgery of the face is a powerful tool to alter the facial skeleton; the facial form is enhanced through the use of alloplastic implants and osteotomies of the facial bones. However, the ultimate aesthetic appearance is dictated by how the soft tissue envelope drapes over the altered skeletal foundation. Intraoperative and postoperative fat grafting enhances the fi...

Compared to other techniques of propagation, grafting is the most successful and feasible technique for asexual propagation of walnut plants. There is little information about graft union formation in walnut. Therefore, the objective of this study was to evaluate histological events during graft union formation in Juglans regia L. cv. Chandler scions when minigrafted on the one-year-old seedlin...

hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...

BACKGROUND Polyostotic fibrous dysplasia is a skeletal disease that results from somatic activating mutations in the gene GNAS in skeletal stem cells, leading to proliferation of immature osteogenic cells with replacement of normal marrow and bone with fibro-osseous tissue. Lesions may cause bone deformity or fracture. In the surgical care of polyostotic fibrous dysplasia, the role of grafting ...
