introduction: in open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. this study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    materi...

background. one of the treatment methods for facial fractures is close reduction technique, but treatment with intermaxillary fixation (imf) interferes with normal nutrition, and malnutrition can affect patient’s recovery. anthropometric measurements such as skinfold thickness and body mass index (bmi) are universal indexes for diagnosing malnutrition. so in this study we pointed out how treatm...

conclusions this approach may be an appropriate approach to the zygomatic arch in the zmc fractures and eliminates the use of the coronal flap. introduction zygomatic arch fractures are common injuries in the maxillofacial injuries. sometimes it is necessary to fix the unstable fragments of the zygomatic arch. case presentation we introduce a combination of transconjunctival and lateral canthot...

cyanobacteria were collected and identified in five paddy fields with different soil textures of golestan province in iran. it was determined that nostoc ellipsosporum and nostoc muscorum were dominant in all sites among 20 species. to assess the ability of atmospheric nitrogen fixation by the species, their pure cultures were provided by growing on bg-11 solid culture medium. subsequently, eac...

rotavirus is the most important pathogen responsible for acute diarrhea in infants and young children. the incidence of rotavirus infection was studied in 156 children less than six years of age who were suffering from acute gastroenteritis, between february 22, 2006 and february 21, 2007 in mashhad. rotavirus antigen was detected by latex agglutination test (rotascreen) in 28.8% of the stool s...

abstract this study was conducted to investigate, under incubation conditions (fc moisture and temperature of 30o c), the effect of the potassium concentration and the cultivation background on the k- fixation in khuzestan’s sugarcane under-cultivation soils. for this reason, 70 complex soil samples in 35 pairs each coupled out of two different depths (0-30 and 30-60 cm), chosen from the under-...

background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...

conclusions despite the complications of fixation with the dhs device, it remains the most successful for treatment of intertrochanteric fractures. background according to the existing literature, the dynamic hip screw (dhs) is the preferred standard for the treatment of intertrochanteric fractures. however, some surgeons use other devices such as the locking compression plate (lcp). objectives...
