اثر تنش خشکی بر تجمع پرولین و تغییرات عناصر در یونجه های یزدی ،نیکشهری و رنجر
خشکی از جمله تنش های محیطی مهم است که بر رشد و نمو گیاهان اثر دارد . برای شناسایی مکتنیزم های مقاومت به تنش خشکی در یونجه آزمایشی در محیط هیدروپونیک با 4 سطح مختلف پتانسیل های اسمزی حاصل از PEG شامل صفر ،4 - ،8- و 12- بار انجام شد . نتایج نشان داد...
Synthesis and cytotoxic evaluation of poly(ethylene glycol)-coated superparamagnetic nanoparticles
in biological media, they were coated with poly(ethylene
glycol) (PEG). Then, the cytotoxic effect of PEG@Fe3O4 nanoparticles on
osteosarcoma cells (Saos-2 cells) was evaluated. Cells were treated with different...
The Effect of Different Polymer Length on Water Droplets of Reverse AOT microemulsion
We study the effect of polyethylene glycol (PEG) on the dynamic and structure of water droplets at the reverse sodium bis-(2-ethylhexyl) sulfosuccinate (AOT) microemulsion. The mixture of water and oil with anionic surfactant AOT can form...
بررسی اثرات تنش خشکی ناشی از پلی اتیلن گلایکول بر جوانه زنی و خصوصیات مورفوفیزیولو ژیک گیاه شوید(Anethum graveolens L.)
به منظور بررسی واکنش گیاه دارویی شوید به تنش خشکی ناشی از پلی اتیلن گلایکول در مراحل جوانه زنی و رشد رویشی دو آزمایش جداگانه هر
یک به صورت فاکتوریل در قالب طرح کاملاً تصادفی با سه تکرار انجام شد. در آزمایش اول واکنش ...
Comparison of polyethylene glycol effect on hydroxyapatite morphology produced into different methods: sol–gel and precipitation
of importance of morphology, in the current research nano-sized HA particles were produced using sol–gel and precipitation methods, and to change the morphology, polyethylene glycol (PEG) was used as an organic modifier. The produced samples were characterized...
Comparison of poly-ethylene glycol effect on hydroxyapatite morphology produced into different method : sol-gel and precipitation
of morphology, in the current research nano sized HA particles were produced using sol-gel and precipitation methods and to change the morphology poly-ethylene glycol (PEG) was used as an organic modifier. The produced samples were characterized using X...
Inhibition of gene expression by DNAi
this process, the transferring DNA molecules to the nucleus plays a very important role in the success of the DNAi transfection. The use of PEI-PEG beads today is important as the best nanoparticle DNA and can produce the least toxicity. In this case...
