Introduction: It is reported that migraine may be risk factor of brain cancers. Since the one of the best ways to assess this possible relationship is molecular mechanism study, here the common central dysregulated proteins between these diseases are investigated via network analysis. Methods: The dysregulated proteins of migraine and gliosarcoma are extracted from STRING database and interact...

Background Central venous catheter (CVC) is used for measuring hemodynamic variables, transfusion of blood, fluids and medications when peripheral vascular lack sufficiency. Unfortunately CVC is associated with many complications ranging from anxiety and discomfort for the patient to severe mechanical side effects such as arterial lacerations, pleural and pericardial injury as well as infection...

In this study, we give the relationships between the conical curvatures of ruled surfaces generated by the unit vectors of the ruling, central normal and central tangent of a ruled surface in the Euclidean 3-space E^3. We obtain differential equations characterizing slant ruled surfaces and if the reference ruled surface is a slant ruled surface, we give the conditions for the surfaces generate...

this paper tries to evaluate the nature of open market operation in the conventional banking system and to compare the usage of government securities and central bank securities for conducting this operation. in addition, the experience of the iranian central bank in using central bank musharakah certificates is reviewed. the main results of the paper, derived from an analytical- descriptive ap...

Once the responsibilities of central bank increases, developing good governance for achieving its different aims to satisfy the required statutory power becomes more complicated. In the case of the central bank of Islamic republic of Iran - as monetary policymaker and supervisor-this issue is valid as well. Considering the necessity of independency, accountability, and transparency for developi...

In this paper, some properties of $alpha$-skew Armendariz and central Armendariz rings have been studied by variety of others. We generalize the notions to central $alpha$-skew Armendariz rings and investigate their properties. Also, we show that if $alpha(e)=e$ for each idempotent $e^{2}=e in R$ and $R$ is $alpha$-skew Armendariz, then $R$ is abelian. Moreover, if $R$ is central $alpha$-skew A...

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...

The fall of Soviet Union and independence of republics of central Asia as well as South Caucasus have brought both chances and challenges for Iran. At first it seemed that Muslim republics, which broke from Soviet Union, might have brought great chances for Iran to promote her ideological claims and economic interests. Dreams of Islamic revolution in new independent central Asian republics invo...

The paper concentrates on the conditions, contingencies and determinants of central bank transparency and communication. From the state of the economy and the quality of national institutions, to the structure of monetary policy committees, the personality of the governor and the nature of the monetary policy framework - with a particular focus on the case of inflation targeting, there i...

A 16-years-old female patient with painless swelling of the right side of mandible is described. She noticed the swelling from two years ago, without painful symptoms. Axial CT imaging showed buccal expansion with intact buccal and lingual cortical bone. The report of incisional biopsy was central odontogenic fibroma. Under general anesthesia the lesion was removed after ostectomy of buccal cor...
