Oral cancer is usually treated combining surgery, radiation therapy and chemotherapy, following effective therapeutic protocols. Severe maxillary and mandibular bone atrophy resulting after therapies are usually treated with autologous bone grafting procedures even though these techniques often present a significant risk of postoperative complications and disadvantages. We describe the case of ...

The goal of this study was improvement of sandy soil using a combination of polystyrene foam container waste and Portland cement. For this purpose, Babolsar sand was used as the base soil. Strips of disposable polystyrene foam container waste in “chips” of 50 ´ 5 mm and 50 ´ 10 mm were added to the soil at 0.0%, 0.1%, 0.2% and 0.3% by weight along with 3% Portland cement at a relative density o...

PURPOSE Our primary aim was to use a rabbit guided bone augmentation model to evaluate whether use of autogeneic bone grafts or bovine bone mineral (BBM) combined with a space-making barrier enhances bone augmentation compared with a barrier alone. MATERIALS AND METHODS Sixteen rabbits were studied. In each rabbit, 2 titanium cylinders, each with 1 titanium lid, were placed subcutaneously in ...

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying  process resulted in a decrease in all fatty acid c...

The human bone marrow (hBM) is a complex organ critical for hematopoietic and immune homeostasis, where many cancers metastasize. Understanding the fundamental biology of hBM in health diseases remain difficult due to complexity studying or manipulating BM humans. Accurate biomaterial-based vitro models microenvironment are further our understanding BM-niche advancing new clinical interventions...

pepino (solanum muricatum), a new vegetable crops, is from solanaceae family and cultivated as annual crops. in order to investigate the effects of mulch on weed dry weight in pepino and soil humidity and temperature, an experiment was conducted based on randomized completely design with three replication at the ferdowsi university of mashhad green house, during 2009. treatments included rice s...

The aim of this study was to retrospectively review the long-term hearing results and the impact of mastoid exclusion/obliteration in patients with cholesteatoma (102 ears) who underwent retrograde tympanomastoidectomy and in whom bone chips/paté were applied as the sole materials during the procedure. In 79 ears, this was combined with ossiculoplasty in a single-stage procedure. In >71% of ear...
