background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

thrombotic thrombocytopenic purpura is the result of multiple thrombus disseminated in small arterioles throughout the body. principle damage is in the endothelium of small vessels and capillaries. from 1982 to 1999, 28 patients (16 female and 12 male) have been treated for ttp. the outcome was evaluated for risk factors and prognosis. these patients were 18 to 69 years old. all had neurologica...

the experimental studies of methane conversion to higher hydrocarbons and methanol using a dielectric barrier discharge (dbd) reactor are presented in this article. the process is carried out at ambient atmospheric pressure and temperature. the dbd reactor is stimulated by an alternative voltage of 50 hz and amplitude of max.23kv. the examination of the effect of voltage and flow rates on metha...

in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

background and objectives: biomaterials are widely used in medical devices such as urinary catheters. one of the main problems associated with long term using of the urinary catheters is biofilm formation on their surfaces. many techniques have been presented to reduce the biofilm formation. one of the most revolutionary techniques allowing such surface fictionalization is plasma surface modific...

a simple, rapid and sensitive high-performance liquid chromatographic (hplc) method for the determination of risperidone in human plasma was developed. an hplc system based on a nucleosil c8 column (150?4 mm) and a uv detector (?= 280 nm) were used. a mixture of sodium dihydrogen phosphate buffer-acetonitrile (55:45, v/v) adjusted to ph 6.0 at a flow rate of 1.5 ml min-1 was used as mobile phas...

objective(s) the purpose of the present study was to evaluate the effect of ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. materials and methods forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (c), fasting (f), training (t) and fasting-training (f-t). the t and f...

background: plasminogen is one of the compounds derived from human plasma. activation of plasminogen produces plasmin. plasmin is able to lyse fibrinogen, fibrin, and some other human plasma proteins. the aim of the present work was to study the separation of human plasminogen by affinity chromatography using gel lysine sepharose. materials and methods: normal human plasma was used as the start...
