Spinal cord injury (SCI) is a trauma that disturbs motor, sensitive and autonomic function and directly impacts the quality of life. After physical damage, releasing of pro-inflammatory proteins and cytokines occurs and with collaboration of immune system cells, an immune response begins in the brain tissue. The result of neuroinflammation is edema, apoptosis and release of axonal growth inhibi...

background helicobacter pylori multiplies and causes infection in human gastric mucosal layer. new approaches have focused on using specific treatments, such as immunotherapy, to limit this infection. urease, as one of the most important virulent and antigenic factors of the bacterium, is a suitable target for this purpose. patients and methods in order to prepare recombinant proteins, the synt...

There has been much interest generated in the recovery of nanoparticulate (nanoparticle) bioproducts(Second generation of biotechnological products) such as plasmid DNA and viruses as putative gene therapyvectors, macromolecular assemblies as drug delivery vehicles and virus-like particles as vaccine components.Such product must be manufactured in advanced stages of purity, ma...

a simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (vpa) in human plasma has been developed. total time for sample preparation and gc analysis is less than 45 min. after plasma protein precipitation, vpa was extracted into chloroform with suitable recovery. by using stabilwax®-da capillary gc column, a symmetrical gas chromatographic peak was ...

A method to quick detect concentration of lecithin in eggs, namely microwave digestion spectrophotometry, was established in this research. The homogenate of eggs was treated with absolute ethanol to eliminate phosphate protein in eggs which could possibly affect concentration of lecithin examined. A sample then received a new way of pre-treatment, called microwave digestion, before UV-Vis ...

background the development of an effective subunit vaccine against brucellosis is a research area of intense. but optimization of recombinant proteins production in escherichia coli and content of endotoxins associated with final recombinant proteins are very important. objectives in the present study, expression and purification of brucella melitensis rhsp and rtf were optimized to reduce endo...

a rapid, sensitive and reproducible hplc method using amperometric detector was developed and validated for the analysis of clarithromycin in human plasma. the separation was achieved on a monolithic silica column (mz- c8 125×4.0 mm) using acetonitrile- methanol-potassium dihydrogen phosphate buffer (40:6:54,v/v), with ph of 7.5, as the mobile phase at a flow rate of 1.5 ml/min. the assay enabl...
