background: today with population growing, surface water is one of the most important water resources used for domestic and industrial consumptions. in order to purify the surface water, coagulants materials are used. the purpose of this study was to assess the possibility of using poly aluminum chloride (pacl) in water refinery number 1 in city of orumieh and investigating its health effects. ...
objective: the aim of this study is to determine if simvastatin pretreatment would change clomiphene response in clomiphene citrate-resistant (cc-r)women with (pcos). materials and methods: this quasi experimental study included twenty five clomiphene resistant women with pcos. all patients received cyclic oral contraceptives pills (ocp) (30µg of ethinyl estradiol and 150µg of desogestrol) from...
The base dependent binding of the cytotoxic alkaloid palmatine to four synthetic polynucleotides, poly(dA).poly(dT), poly(dA-dT).poly(dA-dT), poly(dG).poly(dC) and poly(dG-dC).poly(dG-dC) was examined by competition dialysis, spectrophotometric, spectrofluorimetric, thermal melting, circular dichroic, viscometric and isothermal titration calorimetric (ITC) studies. Binding of the alkaloid to va...
زمینه و هدف : آلفاتالاسمی یکی از اختلالات شایع هموگلوبین میباشد. با توجه به ناهمگونی جهشها و پیچیدگی فنوتیپ در آلفاتالاسمی، تعیین دقیق نوع جهش زوجین، تنها روش برای تعیین وضعیت جنین در رابطه با تالاسمی است. حذفهای شایع در این ژن برای زوجین مشکوک به طور روتین مورد بررسی قرار میگیرد؛ اما جهشهای نقطهای بهدلیل نداشتن اطلاعات کافی در مورد فراوانی آنها کمتر مورد توجه قرار میگیرد. این مطالعه به...
Poly(A)+ and poly(A)- mRNA from HeLa cells were separated and translated in heterologous messenger-dependent protein synthesizing systems. Two-dimensional electrophoretic analysis revealed three classes of polypeptides. At the level of detectability in the electropherograms, a small number (about 10) of proteins were detected only among the poly(A)- mRNA products, a larger number (about 40) wer...
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...
Four carbohydrate derivatives of poly-D-lysine have been synthesized and assayed as substrates for the tissue culture of embryonic mouse cerebellar cells. On poly-beta-(D-glucopyranosyl)-poly-D-lysine and on poly-beta-(N-acetyl-D-glucosaminyl)-poly-D-lysine, dissociated cerebellar cells formed a monolayer. On poly-beta-(D-galactopyranosyl)-poly-D-lysine, cellular aggregates were formed and cabl...
We examined the synthesis, physical properties, and resist properties of various iodine-containing molecules polymers as materials. By condensation reaction 2,6-dimethylphenol (DMP) with 4-iodebenzaldehyde (IBA), 3,5-diiodesalicylaldehyde (DISA) 4-hydroxy-3,5-diiodebenzaldehyde (HDIA), corresponding iodine containing compounds DIPM, 2-DIPM, 4-DIPM were synthesized. The these adamantyl bromo ace...
Background: Natural Killer cells express killer inhibitory receptors specific for HLA-class I molecules. These receptors could induce signals that determine NK cells ability to mediate cytotoxicity. Purified soluble form of HLA class I molecules (sHLA) could bind to NK cell receptors and down-regulate the NK killer function. Objective: To evaluate the influence of sHLA and two monoclonal an...
