One of the benchmarks and tools for investigating the elements of the art is "stylistics", in which the study of literary instruments and rhetorical elements in the language of poets is one of the most accurate and metric methods for the understanding and drawing of poetic images. This quantitative-statistic based, first analyzes and compares two groups of single literary techniques (simile, poem, metaphor, metonymy, and amphibology) and combined techniques (metonymy metaphor, metonymy amphibology metaphor, simile metonymy amphibology metaphor) in five hundred bits of two logical and ritualistic Masnavi (Mosibatnameh and Mantegh Al-teir) and then in the same amount of Rumi's MasnaviManavi and then analyzes them. The results of the research indicate the magnificent rhetoric of Mosibatnameh among the three Masnavi according to using the combined techniques. The amount of Rumi's usage of the single technique "metonymy" and "metaphorical" is so impressive that, taking into account the totality of dingle techniques, MasnaviManavi is better than the other two. But in the field of combined techniques, the MasnaviManavi has the lowest frequency, and it can be said that Rumi has little desire to take advantage of these techniques. However, in the combined section of single and combined techniques, it is considered to be at the higher level than the Mantegh Al-teir and at the lower level than Mosibatnameh. The Masnavi “ Mantegh Al-Teir” in the single techniques section is the least-productive work and is lower than the other two works, and it is considered to be at the higher level than the MasnaviManavi and at the lower level than Mosibatnameh. But in the total number of single and combined techniques, it is lower than two other masnavi.

1. Introduction: If we do not say that Hafez is the greatest employer of the novel technique of ambiguity in Persian, we can at least acknowledge that the novel and unique technique of "ambiguity" is present in the structure of most of Hafez's poems and is among the poets of ambiguity. On the other hand, the use of irony is one of the reasons why Hafez's poetry is widely understood by common groups of people, as Zarrinkoub points out: The use of colloquial words and sarcasm of the common people is also sometimes graceful. By this usage, Hafez's poems will receive a special elegance and we can say that although Hafez's poems are scientific, but the irony doesn't hurt its body. And it gives a special elegance to his poetry, and on the one hand, it is easy to make Hafez’ s words prosperous, even though it is refined, wise, and to an industrial extent, the use of vulgar and market words and allusions (Zarinkoub, 2004). . . .

Introduction: While human endothelial progenitor cells (EPCs) have been a subject of somehow extensive investigation, EPCs from adult mouse hematopoietic system were poorly studied. Present investigation is focused on FVB mouse endothelial progenitor cells in terms of their isolation, purification, and expansion. Materials and Methods: Mononuclear cells collected from murine peripheral blood were cultured in fibronectin coated plate for two weeks, at which point, the adherent cell population were lifted and analyzed in terms of some surface markers. Using FACS Vantage equipped with one-cell deposition unit, single CD34 positive cells were plated per well already containing medium optimized for single cell growth. Several clones were then emerged, expanded, and examined in terms of some surface markers. Furthermore, the cells were investigated regarding ability to uptake DiI-ac-LDL and form capillary network on matrigel surfaces. Results: Adherent population of mononuclear cells from mouse peripheral blood was appeared morphologically heterogeneous. About 5% of the adherent cells were CD34 positive. Having optimized their culture condition, several CD34 positive clones were expanded. The cells comprising the clones were DiI-ac-LDL+ and formed capillary-like tube when being seeded on matrigel surfaces. Conclusion: The primary culture of the mononuclear cells from murine peripheral blood contains a very limited number of cells positive for endothelial lineage markers. These cells (adherent CD34 positive) could be expanded by single cell cloning technique.

Introduction: The present study aimed to compare the capability of two single-file shaping systems in disinfecting and cleaning long oval root canals. Materials and Methods: Fifty single-rooted teeth were prepared, contaminated with Enterococcus faecalis and divided into two groups. Two samplings were obtained,S1 before chemo-mechanical preparation and S2 after the preparation. Depending on the group, chemo-mechanical preparation was performed with XP-endo Shaper (XPS) and Wave One Gold (WOG). Five teeth from each group were observed under scanning electron microscopy (1000×) to evaluate the cleanliness of root canals at 3, 6 and 9 mm from the apex. All probability (P-values) were two-tailed, statistical significance was set at 0. 05 and analyses were conducted using SPSS statistical software. Results: A significant reduction in the colony forming units was observed from S1 to S2 in both tested groups. In S2, XPS group obtained significantly lower colony forming units (P<0. 001). In the cleanliness study, XPS group resulted in significantly cleaner canals compared to WOG. Conclusions: Based on this in vitro study XPS system was more effective in disinfecting and cleaning long oval canals.

The geometrical complexity of some images, especially Indianstyle images, which are not found in the field of traditional expression and which have not been mentioned by scholars in the historical tradition, is such that one must use a suitable tool to analyze them. In the present study, conducted by quantitative statistical analysis, first, frequency was usedto examine and compare the number of single and compound techniques in 500 verses of Bidel’ s sonnets (which were randomly selected from all over his divan). Then, the three compound techniques of “ irony metaphor” , “ metaphorical amphibology metaphor” and “ metaphorical amphibology irony simile” were examined in the structure of images of Bidel. The results of this study show that in both verses of Bidel’ s poems, there is almost onecompound technique; additionally, onethird of Bidel’ s images are created with the help of these techniques, and this means that by contenting ourselves with the four elements of traditional expression (simile, metaphor, irony, and metonymy) and ignoring the literary tools of compounding, the analysis and interpretation of Bidel’ spoems will be incomplete.
