Dibenzo[b,h][1,6]naphthyridines were synthesized in one pot by reacting 2-acetylaminobenzaldehyde with methyl ketones under basic conditions via four sequential condensation reactions. This method was also applied to the synthesis of 1,2-dihydroquinolines. 6-Methyl-1,6-dibenzonaphthyridinium triflates showed strong fluorescence, and the fluorescence intensities were changed upon intercalation i...
Muddy intercalation is one kind of rock’s secondary structural surface, where the failure of instability between strata occurred. Mechanical behaviour of muddy intercalation directly affects the stability of the rock mass. Starting from the micro-structure of Muddy intercalation, revealing its macroscopic mechanical characteristic is of great significance to the stability and optimization desig...
Over the past decades Linear Dichroism (LD) spectroscopy has proven to be a powerful tool for studies of structure and function of different cell constituents, including DNA, cell membranes and proteins. Due to the structural complexity of cell constituents, the LD studies of biomolecules depend on development of simplified model systems, which can mimic the original structure and functionality...
در بخش 1 این پایان نامه برهم کنش افاویرنز به عنوان داروی ضدرتروویروس با dna تیموس گوساله توسط روشهای اسپکتروفتومتری، فلورسانس، دورنگ نمائی دورانی چرخشی، ویسکوزیمتری، الکتروشیمی و همچنین تاثیر آنها بر روی شکستن رشته های پ بررسی گردید.بر اثر افزایش dna تغییرات قابل توجهی در طیف جذبی دارو بصورت کاهش شدت جذب (hyperchromism) مشاهده شد. علاوه بر این طیف دورنگ نمایی چرخشی تغییرات کانفورماسیونی را نشان...
Dorsal intercalation is a coordinated cell migration event that rearranges hypodermal cells during C. elegans embryogenesis, and that resembles cell intercalation in many systems from flies to mice. Despite its conservation, the molecular mechanisms that govern dorsal intercalation in worms have remained elusive. Here, we comment on our recent publication, Walck-Shannon et al.,(1) which begins ...
