in this work, poly (o-anisidine) (poa) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of carbon paste electrode (cpe). nickel ions were dispersed into the polymer by immersing the electrode in niso4 solution. the prepared ni/poa/cpe was characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy (afm) a...

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...

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...

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...
