Background and purpose: Microfluidic systems are microstructures that could be used to improve the conventional cell culture protocols used in laboratories. The aim of this research was to design and construct the microfluidic system and evaluating its ability to produce IL-2 by jurkat cells. Material and methods: At first, the sketch of microfluidic canals was designed by Corel draw and wa...
the effect of poss instruction in comparison with conventional instruction on development of esp learners’ parts of speech knowledge and attitude toward call.
هدف این تحقیق بررسی تأثیرات انجماد شیشه ای کمپلکس های تخمک–کومولوس (توده های coc) گوسفند بر بقای توده ها، بلوغ تخمک ها، بیان ژنهای بلوغ و آپوپتوزی، شیوع ناهنجاریهای کروموزومی و تغییرات فراساختاری توده ها بود. توده های coc جدا شده دارای کیفیت خوب به چهار گروه، غیرانجمادی کنترل، انجمادی conventional straw ، cryotop و solid surface تقسیم شدند. در گروههای انجمادی conventional straw وcryotop، توده...
aqueous polymer quenchants are being used increasingly in steel heat treatment industries as a substitution for conventional quenchants. by adjusting the quench parameters of the polymeric media, it is possible to achieve desirable microstructure and mechanical properties in addition to reduction in distortion and cracking. in this work, polyalkylene glycol (pag) aqueous solution was used as th...
objective: when none of digital systems and scanners is accessible and it is essential to have digitized images of conventional radiographs, digital cameras can be used. the aim of this study was to investigate whether digital images obtained by different resolutions of a digital camera are matched to the original radiographs in evaluation of caries. methods: in this diagnostic accuracy in vitr...

Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the null-geodesic equations obtained from the Lagrangian method, as well as ray-tracing equations obtained from the Plebanski’s equivalent medium theory. All calculations are done for the Schwarzschild geometry, which resu...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
OBJECTIVE To compare three different in vitro maturation (IVM) media for immature oocytes. DESIGN Experimental study. SETTING In vitro fertilization laboratory. ANIMAL(S) BDF1 female and male mice. INTERVENTION(S) Retrieval and maturation of cumulus-enclosed germinal vesicle-stage oocytes according to one of three protocols: group A, conventional IVM medium; group B, blastocyst culture ...
