Ionomics is the study of elemental accumulation in living organisms using high-throughput elemental profiling. In the present study, we examined the ionomic responses to nutrient deficiency in maize grown in the field in long-term fertilizer trials. Furthermore, the available elements in the field soils were analyzed to investigate their changes under long-term fertilizer treatment and the iono...

Potassium permanganate has become an established fixative in electron microscopy (Luft, 1956) and has special value in the study of cell membranes. During an investigation of methods of increasing the contrast in the electron microscope of tissues embedded in epoxy resin, t a solution of potassium permanganate was used to treat the sections, using a technique similar to that of Watson (1958). P...

The rapidly expanding fields of pharmacogenomics and pharmacodiagnostics have presented the pathology laboratories with many challenges and opportunities. As custodians of patient tissues, these laboratories are in the logical position to perform biomolecular testing for proper management of patients. In order to meet these challenges, the pathology laboratories of the twenty-first century shou...

conclusions due to our satisfactory test results, the brief training, the steep learning curve and the radiation-free technique the new device has to be considered an appealing alternative for distal locking. objectives our cadaver study was performed to evaluate the accuracy and efficiency of this device. materials and methods in two runs, 30 probands (group 1: 10 students; group 2: 10 residen...

conclusions although external fixation in open pediatric fractures and severe injuries is recommended, intramedullary nailing is also an effective method with low complications. combining pins and flexible intramedullary nails is effective in developing more stability and is not associated with more complications. background tibial fractures are the third most common pediatric long-bone fractur...

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...
