O-16: Comparison of Pre-Antral Follicle Culture Development during 2 Dimensional and 3 Dimensional Culture Systems
Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...
متن کاملSyntactic Structures in Research Article Titles from Three Different Disciplines: Applied Linguistics, Civil Engineering, and Dentistry
Deducing what a paper is about, titles are considered as the most important determinant of how many people will read the article. Therefore, studying the use of different syntactic structures and their rhetorical functions in titles is of great significance. The current study was set to investigate these structures used in research article titles in three disciplines of Applied Linguistics, Den...
متن کاملTopography measurements and applications in ballistics and tool mark identifications*
The application of surface topography measurement methods to the field of firearm and toolmark analysis is fairly new. The field has been boosted by the development of a number of competing optical methods, which has improved the speed and accuracy of surface topography acquisitions. We describe here some of these measurement methods as well as several analytical methods for assessing similarit...
متن کاملPredicting three-dimensional displacement around the tunnel and its impact on the value of Q-system
Having knowledge of stability of an underground space depends on stresses and strains around it. Creating underground tunnels leads to significant changes in the rock mass stress. Therefore, to achieve the necessary stability, stresses and deformations around the tunnel must be examined carefully. Usually, stress-strain behavior analysis is conducted in two-dimensional mode. This paper was cond...
متن کاملCorneal Ectasis among Wrestlers: Report of Two Cases
Report keratoconus in two patients with a long history of wrestling without any risk factor for corneal ectasia and reviewing the possible pathogenesis. To confirm suspicion of keratoconus, corneal topography was performed using scanning slit topography system and Orbscan. In two wrestlers with the complaint of visual loss in their eyes and IOP raising, corneal topography was performed and de...
