a rapid and sensitive hplc method has been developed for the quantification of mirtazapine (mrz), a noradrenergic and specific serotonergic inhibitor antidepressant (nassa) and its two major metabolites n-desmethylmirtazapine (ndm) and 8-hydroxymirtazapine (8-ohm) in human plasma. the separation was achieved using chromolith c18 column and a mobile phase of acetonitrile: phosphate buffer (ph=3,...

An interaction of plasma flow with an arc-anode attachment in a dc arc plasma torch was investigated. Statistical processing of the photographic images of plasma jet was used for analysis of an effect of the anode attachment on structure and stability of plasma flow. Deflection, flattening and flutter of the plasma jet was found to be caused by disturbing effect of the arc-anode attachment.

In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...

Wind-tunnel experimentswere conducted on a 47-deg sweep, scaled 1303unmanned air vehiclemodel to assess the performance of an innovative windward-surface plasma actuator design for flight control at low angles of attack. Control was implemented by altering the flow past an aft separation ramp on the windward side using a single dielectric barrier discharge plasma actuator. The influence of ramp...

Infusion of small amounts of blood plasma into isolated, isovolumic rabbit hearts perfused with Tyrode's solution resulted in coronary vasoconstriction followed by a decrease in left ventricular developed pressure and dP/dt. Maximal effects were obtained with a perfusate plasma concentration of 1%. Increasing the plasma concentration beyond 1% did not appreciably increase the coronary vasoconst...
