A simple, precise, and rapid method to measure plasma malondialdehyde (MDA) was developed by use of solvent extraction--flow-injection analysis. The reagent solution, containing thiobarbituric acid (TBA), 5 g/L in 100 mL/L phosphoric acid, and extraction solvent (methylisobutyl ketone, MIBK) were propelled with a double-plunger micropump at a flow rate of 0.3 mL/min, and 20 microL of sample was...

    In this double blind crossover study we assessed the bioequivalence of 200 mg enteric coated sodium valproate tablets manufactured by Roozdarou with 200 mg enteric coated sodium valproate (Orlept) manufactured by Desitin, Germany. Twelve healthy male volunteers were administered a single dose of 600 mg sodium valproate manufactured by Roozdarou, followed by a similar dose of Orlept, 2 weeks...

Low temperature plasma assisted nit riding treatments of 316 stainless steel produce a complex layer constituted by tow different metastable f.c.c. solid solution denoted ( γ N1 and γ N2 ). About the formation of these double layers, different hypothesis was proposed in the literature. For verifying these hypotheses, the effects of differentes conditions such as nit riding temperature, cleaning...

OBJECTIVES To develop an equation to predict dual plasma sample method (DPSM) (99m)Tc-diethylene triamine pentaacetic acid ((99m)Tc-DTPA) plasma clearance from single plasma sample method (SPSM), and to clarify the condition in which DPSM can be substituted by SPSM in measurement of glomerular filtration rate (GFR). METHODS Patients with chronic kidney disease (CKD) were selected. Watson modi...

Background: Platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. Platelet concentrates can be prepared by the apheresis method or from the whole blood using the Buffy-coat or Platelet-rich plasma methods. The purpose of this study was to compare four variations of platelet-rich plasma method based on double...

the main aim of this research was to investigate the effects of plasma nitriding parameters including frequency and duty cycle for a seris of test samples with different grooves during conventional plasma nitriding (cpn) and active screen plasma nitriding (aspn) treatments. the sample assemblies were consisted of rectangular grooved steel blocks with different groove dimensions of 2, 4, 6, 8 an...

background: equine chorionic gonadotropin (ecg) is commonly used in association with a progestagen treatment to synchronize estrus of goats and ewes during breeding and non-breeding seasons. classical purification of the ecg from serum includes ph fractionation with metaphosphoric acid two ethanol precipitation steps as well as dialysis followed by fixed-bed chromatography. objectives: the aim ...
