Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...

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...

this article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (mtx) in plasma. samples were collocted from children receiving high-dose mtx at shafa hospital (ahvaz university of medical sciences, ahvaz, iran) at various times after the end of eachinfusion. plasma was deproteinized with trichloroacetic acid and the supernatant was i...

a rapid, simple and sensitive high-performance liquid chromatography method was developed for determination of ciprofloxacin in plasma by means of ultraviolet detection. ofloxacin was used as an internal standard and separation carried on a novapak c18 column using a mobile phase of 0.01 m phosphate buffer (ph =2.6): methanol (82: 18 v/v). extraction of drug was performed from plasma by liquid-...

background: the present study was undertaken to estimate and compare the levels of plasma total cholesterol (tc), low density lipoprotein (ldl), high density lipoprotein (hdl), very low density lipoprotein (vldl) and triglycerides in patients with oral precancerous lesions/conditions, oral cancer and normal subjects. materials and methods: the study comprised of 60 patients with oral precancero...

results mean ± standard deviation (sd) of plasma zinc levels was determined as 0.78 ± 0.22 mg/l. also zinc level was 0.76 ± 0.19 mg/l and 0.80 ± 0.24 mg/l in thalassemic and non thalassemic patients, respectively. t-test analysis showed that there is no significant difference between these two groups regarding plasma zinc level (p = 0.235). conclusions it is concluded that zinc level of studied...

An analysis of the demands of ULSI and GSI technologies shows the necessity of multi-layer devices to reduction of signal transmission delay time. This reduction is realized by using a better conductor metal, such as Cu and a surrounding insulator with low capacity than actually used, such as Dow Cyclotene 3022. In this paper, the results of evaporated and sputtered Cu to Dow Cyclotene 3022 wer...
