Objective(s): Dispersive liquid-liquid microextraction coupled with gas chromatography (GC)-flame ionization detector was developed for the determination of valproic acid (VPA) in human plasma. Materials and Methods: Using a syringe, a mixture of suitable extraction solvent (40 µl chloroform) and disperser (1 ml acetone) was quickly added to 10 ml of diluted plasma sample containing VPA (pH, 1....
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background and aims. the accelerating effect of plasma rich in growth factors in the healing of extraction sockets has been shown by some studies. the aim of the present investigation was to evaluate the effect of deproteinized bovine bone matrix (dbbm) with and without plasma rich in growth factors (prgf) in canine extrac...
in this study, simple and efficient ultrasound-assisted emulsification microextraction (usaeme) combined with gas chromatography-flame ionization detector (gc-fid) was developed for the preconcentration and determination of carbamazepine in biological samples. in this method, the fine droplets of 1-octanol were formed and dispersed in the sample with the help of ultrasonic waves, which accelera...
in this study, a high-performance liquid chromatographic method (hplc) and uv spectrophotometric method were developed, validated and applied for the determination of theophylline in biological fluids. liquid- liquid extraction is performed for isolation of the drug and elimination of plasma and saliva interferences. urine samples were applied without any extraction. the chromatographic separat...
Background and Objective: Visfatin a 491 amino acid peptide is expressed as a Pre-B cell colony-enhancing factor or Nicotinamide phosphoribosyltransferase and might be regulated by several factors such as nutritional status, physical stress, suggesting a regulatory role of peripheral visfatin in energy homeostasis. The purpose of the present study was to investigate the effects of endurance t...

the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
A simple and reproducible HPLC method with spectrophotometric detection was developed for determination of rivastigmine in human plasma. Liquid-liquid extraction of rivastigmine and donepezil (as internal standard) from plasma samples was performed with 1-butanol/n-hexane (2:98 v/v) in alkaline condition followed by back-extraction into diluted acetic acid. Chromatography was carried out using ...
