brain injury is a complex event leading to tissue damage and functional deficits by primary and secondary mechanisms. since the application of tissue engineering approaches is a new topic in the treatment of brain injury, producing a proper experimental model to evaluate the effects of tissue engineering products on damaged brain tissue is required. in the present study, a simple and reproducib...
Introduction: Identifying the potential firing patterns following different brain regions under normal and abnormal conditions increases our understanding of events at the level of neural interactions in the brain. Furthermore, it is important to be capable of modeling the potential neural activities to build precise artificial neural networks. The Izhikevich model is one of the simplest biolog...
Abstract Background : The aim of this study is to determine of risk factors in patients with brain metastases, and prognostic factors affecting survival of patients by using the Cox proportional hazards model. Methods : This descriptive - analytic retrospective study was performed on 197 patients with brain metastases who Referred to Shahid Ramezanzadeh Radiation Center, Yazd, Iran. Several ris...
Background and Objective: One of the major side effects of cerebral ischemia is the water content enhancement in brain tissues which leads to mortality enhancement. Recently, therapeutic strategies have been focusing on preconditioning mechanisms. Erythropoietin as a glycoprotein hormone with anti-inflammatory and antioxidant effects on brain may be effective on brain edema reduction. Mate...

Elite migration and brain drain trend in Iran have undergone a dramatic ascent in the past few decades while we are seriously in need of educated manpower to help accomplish the 20-year national vision. So to consider brain drain is necessary and must be accounted by policymakers in all levels. In the upcoming paper, we study the brain drain as a social problem and elaborate a five-dimensional ...
Background : Brain injury by transient complete global brain ischemia (cardiac arrest) and regional incomplete brain ischemia (ischemic stroke) afflicts a very large number of patients with death or permanent disability. Recent studies suggest that olive extracts suppress inflammation and reduce stress oxidative injury. Methods: The aim of the study was to evaluate the effect of dietary Oli...
background & objectives: ischemic stroke is the third leading cause of death and disability in most of the human societies. there is no effective treatment due to complexity of the pathophysiological mechanisms. today, more researches are designed to introduce involving factors and new treatment strategies in brain ischemia. the objective of this study is to introduce an experimental model of t...
