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 ...

A simple, rapid and sensitive method termed as magnetic solid phase extraction (MSPE) combined with high-performance liquid chromatography-ultraviolet detector (HPLC-UV) has been proposed for the determination of trace amounts of chlorpromazine (CPZ) in water, urine and plasma samples. The separation and determination was performed on a C18 column under the optimal chromatographic conditions. S...

Modeling of ion beam extraction from an ECRIS requires special procedures in order to achieve results similar what is found experimentally. The initial plasma conditions must be included for consistency between experiment and simulation. Space charge forces their compensation the extracted become important with increasing intensity. Here we consider various beam-plasma that occur along any line.

We investigate the interaction between a heavy quark-antiquark pair in color octet configuration gluon plasma. calculate nonperturbatively an effective thermal potential for such through study of correlation function hybrid state with $Q \bar{Q}$ and adjoint source static limit. discuss extraction potential, present results plasma moderately high temperatures $\lesssim 2 T_c$. The implications ...

Amplification of human immunodeficiency virus type 1 (HIV) reverse transcriptase (RT) and protease (PT) sequences from plasma is difficult when HIV RNA levels are low, and it usually cannot be accomplished in samples with <1,000 HIV RNA copies/ml. Because the RNA extraction step is critical for the success of subsequent amplifications and sequence analyses, two RNA extraction methods were compa...
