Abstract Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic,anti-infammatory and antipyretic actions. It is used to relieve mild to moderate pains. Solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . Poly allyl glycidyl ether/iminodiacetic acid-co-N, N-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

the main purpose of this research is to determine the effective factors in adopting biological control in the farmer field school approach. the method used in this research is descriptive-correlation and comparative, which has been done by survey. the rice farmers of the township of babol, mazandaran, iran were selected as the sample population of this research. the statistical sample of the re...

the management of sedimentation problems in rivers and reservoirs depend greatly on the sediment yield from the catchment land surface. in this research the effects of biological measures and ranges enclose on suspended load in two sub-catchments of kakhk experimentalwatershed in gonabad has been studied. this catchment contains both control and experimental sub-catchments. these sub-catchments...

Biological sample pretreatment is an important step in biological sample analysis. Due to the diversity of biological matrices, the analysis of target substances in these samples presents significant challenges to sample processing. To meet these emerging demands on biopharmaceutical analysis, this paper summarizes several new techniques of on-line biological sample processing: solid phase extr...

Proteomics is the large-scale study of the structure and function of proteins in complex biological sample. Such an approach has the potential value to understand the complex nature of the organism. Current proteomic tools allow large-scale, high-throughput analyses for the detection, identification, and functional investigation of proteome. Advances in protein fractionation and labeling techni...

Present work describes the fluorescence spectroscopy determination of (6-TG) using silver nanoparticles (AgNPs). The acridine could be electrostatically adsorbed to the surface of the citrate-stabilized silver nanoparticles. Upon addition of 6-TG, the acridine is replaced from the surface of AgNPs which induce the aggregation of AgNPs. Under optimum condition, the fluorescence intensity enhance...
