A rapid and sensitive HPLC method was developed for determination of losartan in plasma. Losartan was extracted from plasma by a two-step extraction procedure using chloroform as extracting solvent in acidic medium. HPLC analysis was performed on a cyano reversed-phase column using phosphate buffer (pH 4.3), acetonitrile (750:250, v/v) as mobile phase with a flow rate of 0.9 mL/min. Sodium dicl...

A mathematical model for blood flow in narrow capillaries under the effect of transverse magnetic field has been investigated. It is assumed that there is a lubricating layer between red blood cells and tube wall. The transient flow of the fit red blood cell surrounded by plasma annulus in the narrow capillary is considered. The analysis of fluid flow between red cell and tube wall, when the ce...

“Plasma hole” is a singular vortex spontaneously formed in an electron cyclotron resonance plasma. So far the ion flow velocity field associated with the plasma hole has been measured with a directional Langmuir probe (DLP). Here we present the first result of measuring azimuthal and radial flow velocity profiles of the plasma hole in an argon plasma using a laser induced fluorescence (LIF) Dop...

CONTEXT Accurate quantitation of bone marrow plasma cells is an important component in the diagnosis and posttreatment assessment of plasma cell dyscrasias. Although flow cytometry is sometimes used for this purpose and can rapidly evaluate many cells, the accuracy of flow-based plasma cell quantitation compared with morphologic assessment (currently the gold standard) is uncertain as direct co...

The Atmospheric Pressure Chemical Vapor Synthesis (APCVS) route is a process that can be used for the synthesis of doped-nanocrystalline powders with very small crystallite sizes having a narrow particle size distribution and high purity. In this study, APCVS technique was used to prepare boron-doped titania nanopowders. The effects of temperature, borate flow rate and water flow rate on the am...
