INTRODUCTION In periapical surgery, the absence of standardization between different studies makes it difficult to compare the outcomes. OBJECTIVE To compare the healing classification of different authors and evaluate the prognostic criteria of periapical surgery at 12 months. MATERIAL AND METHODS 278 patients (101 men and 177 women) with a mean age of 38.1 years (range 11 to 77) treated w...

This study is focused on developing an integrated optimization-simulation model to develop the operation policies for a multi-purpose reservoir. Objective function of the optimization model is considered to be a linear function of reliability, resiliency, and vulnerability of river-reservoir systems. Genetic Algorithm (GA) is used to solve the optimization model in which the coefficients of the...

Morphological udder traits have recently become of greater interest from farmers to researchers. In dairy ewes, the udder is very important due to its physiological and conformational characteristics. External udder traits were measured in ewes (Ovis aries L.) of nine genotypes (355 ewes) created of the basis of Improved Valachian (IV), Tsigai (T), and Lacaune (LC) breeds (six traits; 1185 data...

 Background: As a major responsibility, health authorities must control rational prescription of drugs (RUD). A way to analyze the regional status of drug prescription is the WHO’s recommended indices. The purpose of the study was to determine the status of drug prescriptions in pharmacies of healthcare centers under the authority of Tehran University of Medical Sciences based on the WHO indice...

We discuss a figured pin from Shahdad, previously well known but published with a partial and unsatisfactory drawing.  More detailed observations and a new, more realistic recording of this important artifact reconsider its stylistic and iconographic links with the imagery of the Halil Rud civilization and the eastern Iranian Plateau in general, and, at its opposite cultural poles, with Mesopot...

The main responsibility for the rational use of drugs (RUD) in children belongs to parents. aim this study was determine knowledge and awareness level parents about RUD children. included literate volunteer with no learning disability. drug scale (RDUS), developed by Demirtas, modified assess parents' (higher score indicates higher level). Questionnaires which all questions were not answered ex...

patients warranted additional i.v. anaesthetic prior to application of the electrical stimulus. Fortunately, neither of the patients reported awareness of the procedural events. Consequently, we no longer use bispectral index monitoring alone to assess pre-ictal anaesthetic depth in patients receiving ECT. Moreover, Zand and colleagues recently reported that the BISwas not a reliable monitorof ...
