multiple myeloma (mm) characterized by proliferation of plasma cells in bone marrow and production of monoclonal immunoglobulin's. recently, arsenic trioxide (ato), has been considered for treatment refractory mm. we assessed the safety and efficacy of ato for patients with refractory mm. a phase 2, study of arsenic trioxide was conducted in 12 mm patients, whose refractory to two standard ther...

a capillary electrophoresis method was used for assay of some degradation products of carvedilol. the optimized parameters were as; running buffer 80 mm acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kv, temperature is 20 ºc and the wavelength range of 200-350 nm. the results indicate that the proposed ce method could effectively separate carvedilol from its de...

Abstract The objective of this work was to evaluate microfluidic chip electrophoresis, known as lab-on-a-chip technique, for the detection milk adulteration using cheese whey in comparison with SDS-PAGE. Raw, pasteurized, processed at an ultra-high temperature (UHT), and powdered samples received increasing concentrations (0, 1, 2.5, 5, 10, 20, 30, 50, 100% v/v), were subjected electrophoresis ...

Two steps of enzymatic oxidations from hypoxanthine to uric acid with xanthine oxidase (XOD) were kinetically analyzed by capillary electrophoresis/dynamic frontal analysis. When a substrate solution was introduced into separation buffer containing XOD, the reaction continuously proceeded during electrophoresis and product resolved zone. A plateau signal detected based on constant rate XOD. The...

Forensic DNA analysis has vastly evolved since the first forensic samples were evaluated by restriction fragment length polymorphism (RFLP). Methodologies advanced from gel electrophoresis techniques to capillary and now next generation sequencing (NGS). Capillary was still is standard method used in analysis. However, dependent upon information needed, there are several different that can be t...

The synthesis of keratin proteins during development of the embryonic chick feather was studied by quantitative gel electrophoresis of the reduced and carboxymethylated proteins. The results demonstrated a coordinated synthesis of the major keratin proteins, during and after the onset of keratin synthesis. The results from gel electrophoresis correlated well with electron microscope visualizati...

Protein-rich wheat bran aqueous extract was fractionated by size exclusion chromatography. Each of the chromatographic fractions hydrolyzed with V8 protease in a reaction medium containing Ca2+. Both and hydrolysates were characterized physically chemically. The objective to obtain information about which components are involved formation nanoparticles, reported previous works. Six from 0.3 102...

In proteomics research chemical as well as physical methods are used to detect proteins subsequently to their separation. Physical methods are mostly applied after chromatography. They are either based on spectroscopy like light absorption at certain wavelengths or mass determination of peptides and their fragments with mass spectrometry. Chemical methods are used after two-dimensional electrop...

Introduction: In this study, the effect of para-nonylphenol as an environmental pollutant on viability, morphology and proliferation of bone marrow mesenchymal stem cells was investigated. Methods: Bone marrow mesenchymal stem cells of rat were treated with the 0.5, 1, 2.5, 3.5 and 5 μM of paranonylphenol for a period of 21 days, then the viability of the cells were estimated using trypan bl...
