The geographical variation in Helicobacter pylori genotypes is an observed phenomenon. Cytotoxin associated genes A (cagA) and E (cagE), and vacuolating cytotoxin (vacA) genotypes of H. pylori are associated with peptic ulcer disease (PUD). This study compared the distribution of these genotypes in Iranian and Afghani isolates and their association with clinical outcomes. H. pylori infected pat...

BACKGROUND Metabolic syndrome (MetS), a cluster of cardiovascular risk factors, is one of the most common metabolic disorders, which lead to many chronic diseases.

This study aims to systematically review the prevalence of MetS among Iranian children and adolescents. MATERIALS AN...

Two things are striking about this medieval definition. The first is that it is very close to the modern conception of formal consequence one finds in Bolzano and Tarski3.

Why are these distinctions d...

Derived varieties were invented by P. Cohn in [4]. Derived varieties of a given type were invented by the authors in [10]. In the paper we deal with the derived variety Vσ of a given variety, by a fixed hypersubstitution σ. We introduce the notion of the dimension of a variety as the cardinality κ of the set of all proper derived varieties of V included in V. We examine dimensions of some varie...

This paper develops a probabilistic reconstruction of the No Miracles Argument (NMA) in the debate between scientific realists and anti-realists. The goal of the paper is to clarify and to sharpen the NMA by means of a probabilistic formalization. In particular, I demonstrate that the persuasive force of the NMA depends on the particular disciplinary context where it is applied, and the stabili...

The area of Esfordi-Zarigan in Central Iran is located in Bafq metallogenic province where most the rock units belong to Precambrian, Infracambrian and Cambrian periods. Although the sedimentary and volcanic rocks are widely distributed, this research is mainly focused on petrogenesis of plutonic rocks. From stratigraphic point of view sedimentary and volcanic rocks can be classified in five ma...
