Thermodynamic studies on the interactions between intercalator-neomycin conjugates and a DNA polynucleotide triplex [poly(dA).2poly(dT)] were conducted. To draw a complete picture of such interactions, naphthalene diimide-neomycin (3) and anthraquinone-neomycin (4) conjugates were synthesized and used together with two other analogues, previously synthesized pyrene-neomycin (1) and BQQ-neomycin...
Considering the largely chiral nature of biological systems, there is interest in drug delivery systems. Here, we investigate for first time polymer micelles based on poly(2-oxazoline) (POx) ABA-type triblock copolymers with and racemic hydrophobic blocks formulation achiral drugs. Specifically, poly(2-ethyl-4-ethyl-2-oxazoline) (pEtEtOx) poly(2-propyl-4-methyl-2-oxazoline) (pPrMeOx) were used ...
poly methyl methacrylate (pmma) is the most common material used in prosthodontics. several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes cross linking or copolymerization. the innovative method for improving the physical properti...

چکیده سابقه و هدف: برای تولید سلول های دندریتیک از مونوسیت های خون محیطی انسان، آزمایشگاه های مختلف عوامل بلوغ متفاوتی را به کار می برند. ما در این مطالعه تأثیر افزودن poly(i-c) به عوامل بلوغ متداول یعنی mcm و tnf-α را در القاء پاسخ لنفوسیت های t مورد بررسی قرار دادیم. مواد و روش ها: مونوسیت های خون محیطی که پس از دو ساعت انکوباسیون در دمای c°37 به فلاسک کشت چسبیده بودند به مدت چهار روز در حضور...
