in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
مدل جمعی بوهر یکی از مدلهای هسته ای است که برای انرژی های تحریک پایین در هسته های زوج زوج بکار می رود و داده های بدست آمده ازاین مدل، با تقریب خوبی نسبت به سایر مدل ها با داده های تجربی مطابقت دارد. نتایج تحلیلی با روشهای تقارن دینامیکی برای مدل قطره- مایع هسته ای نیز قابل محاسبه است. در این پروژه به یک سیستم چند ذره ای با پتانسیل های مستقل از?ی نوسانگر هارمونیک و پتانسیل دیویدسن بصورت ?^2+(?_...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
Stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells. Stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions. However, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...
While a precise forecast for the next decade is clearly impossible, some of the major challenges that need to be addressed in the next 10-20 years can be identified. These include problems of repositories, the changing scope of cultural heritage; new links between national, regional and local; between culture, knowledge and scholarship; European approaches to intellectual property and to models...
