Traumatic brain injury is considered as one of the main causes of morbidity and mortality worldwide. Apart from primary mechanical injury, Secondary injuries due to inflammation and apoptosis result in great neuronal damage. Current treatments are not able to regenerate the damaged part and prevent future sequels. Using human stem cells with self-assembling scaffolds may be promising in treatme...

Introduction: Brain injury is an important cause of morbidity and mortality worldwide and so far, there has been no absolute treatment for the damaged brain tissue. Using human stem cells with self-assembling scaffolds can be a promising method for treatment of traumatic brain injury. Materials and Methods: Human meningioma stem cells were isolated, cultured and then expanded into in vitro cond...

Bayesian networks are probabilistic models that represent complex distributions in a modular way and have become very popular in many fields. There are many methods to build Bayesian networks from a random sample of independent and identically distributed observations. However, many observational studies are designed using some form of clustered sampling that introduces correlations between obs...

In this paper, we introduce some mathematical features of the concentration factor, a method to extract the information of the conditions of student mental models by analyzing the distributions of students’ responses on multiple-choice questions. We discuss the state density of the concentration factor, the random attractor of SC states, and the transformations between the concentration factor ...

Background Community acquired pneumonia (CAP) is a major infectious cause of mortality in preschool children especially in developing countries. Red Cell Distribution Width (RDW) has been associated with poor outcomes of CAP. We aimed to determine whether admission stress hyperglycemia and RDW can predict mortality in preschool children with CAP for early identification of patients at risk of ...

In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...
