Introduction: Temporal bone osteomyelitis is more commonly seen in immunocompromised patients and is very rare in non-immunocompromised individuals. Mucormycosis is a fulminating fungal infection caused by Mucor which is a saprophytic fungus commonly seen in diabetic patients. Here we report a case of temporal bone osteomyelitis in a child with a traumatic history which was causing clinical fe...

Background: Due to the known disadvantages of autologous bone grafting, tissue engineering approaches have become an attractive method for ridge augmentation in dentistry. To the best of our knowledge, this is the first study conducted to evaluate the potential therapeutic capacity of PRP-assisted hADSCs seeded on HA/TCP granules on regenerative healing response of canine alveolar surgical bone...

background cleft palate (cp) is a common congenital defect. it makes serious difficulties for cleft-affected children. the gold standard of care is autogenous bone grafting which may cause additional problems in donor site along with disappointing results. tissue engineering is a promising solution for a widespread range of defects and disorders. it is reasonable to utilize this novel technolog...

Bioceramic scaffolds such as silicate bioceramics have been widely used for bone tissue engineering. However, their high degradation rate, low mechanical strength and surface instability are main challenges compromising their bioactivity and cytocompatibility which further negatively affect the cell growth and attachment. In this study, we have investigated the effects of silk fibroin coating o...

Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (PCL), poly (vinyl alcohol) (PVA) and hydroxyapatite nanoparticles (nHA). The morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. Scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

Background: Osteoporosis is one of the uncomfortable postmenopausal symptoms. The risk of imbalanced nutrition especially traces elements and vitamins are high during post menopause and may lead to osteoporosis due to reduction of content of mineral bone. The aim of this study was to investigate the potential consequence of Selenium (Se) treatment in ovariectomized rat model with osteoporosis i...
