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...

A limited number of strains belonging to several genera of Rhizobiaceae are capable of expressing a hydrogenase system that allows partial or full recycling of hydrogen evolved by nitrogenase, thus increasing the energy efficiency of the nitrogen fixation process. This review is focused on the genetics and biotechnology of the hydrogenase system from Rhizobium leguminosarum bv. viciae, a freque...

In a time of increasing concerns about the immense energy consumption and poor environmental performance of contemporary processes in the chemical industry, there is great need to develop novel sustainable technologies that enhance energy efficiency. There is abundant chemical literature on process innovations (laboratory-scale) around the plasma reactor itself, which, naturally, is the essenti...

Nitrogen (N) is crucial for crop productivity. However, nowadays more than half of the N added to cropland is lost to the environment, wasting the resource, producing threats to air, water, soil and biodiversity, and generating greenhouse gas emissions. Based on FAO data, we have reconstructed the trajectory followed, in the past 50 years, by 124 countries in terms of crop yield and total nitro...
