هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...
in his recent commentary, gorik ooms argues that “denying that researchers, like all humans, have personal opinions … drives researchers’ personal opinion underground, turning global health science into unconscious dogmatism or stealth advocacy, avoiding the crucial debate about the politics and underlying normative premises of global health.” these ‘unconscious’ dimensions of global health are...
starting from the 6th century a.h., and especially starting from the mongol era onward, along with the flourishing of historiography, historical shāhnāmeh-composition also became a point of interest, and shāhnāmehs appeared with the aim of recording historical events. in the composition of these shāhnāmehs, ferdowsi’s shāhnāmeh was like a model for the shāhnāmeh-writers, and due to this the spi...
The composition of Kuh-e- Barandeh volcanic dome is andesite, dacitic andesite and dacite of calc-alkaline affinity. A prominent feature of this dome is the presence of various types of enclaves with different composition, shape and size. Detailed field and laboratory investigation proved that they are of xenolith and autolith types. The xenoliths are of pelitic and basic protoliths. Xenoliths ...
supported catalysts synthesized via the interaction of mg(oet)2 with ticl4 in the presence or absence of an internal stereoregulating donor (di-n-butyl phthalate), with different solvents (chlorobenzene, n-undecane, n-heptane) at different titanation temperatures have been studied by a set of physicochemical methods. data on the chemical composition, x-ray structure and pore structure of these ...
AspectS is an approach to general-purpose aspect-oriented programming in the Squeak/Smalltalk environment. Based on concepts of AspectJ it extends the Smalltalk metaobject protocol to accommodate the aspect modularity mechanism. In contrast to systems like AspectJ, weaving and unweaving in AspectS happens dynamically at runtime, on-demand, employing metaobject composition. Instead of introducin...
In this study, the effect of nano-titania addition on the mechanical strength of mullite-bonded alumina-siliconcarbide nano-composites was investigated. To this end, the gel-casting process via nano-silica sol was used for shaping the nano-composite.The firing temperature of composition was determined by use of STA. The compressive and bending strengths of samples were measured after firing at ...
Background and Objectives: Essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. Origanum vulgare L. subsp. vulgare is one of the most distributed subspecies within the genus Origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes...
