This study was to evaluate the reduction of dose undulation at the field edge, gap leakage and interleaf transmission by utilizing a dual-level four-bank micro multileaf collimator (mMLC) and compare with standard MLC. Method and Materials: A 6MV Varian 600C linear accelerator has been collimated with a dual-level fourbank mMLC. The dual mMLC consists of four banks of leaves with upper and lowe...
Several in vitro methods have been tested for their ability to predict drug penetration across the blood-brain barrier (BBB) into the central nervous system (CNS). In this article, the performance of a variety of micellar liquid chromatographic (MLC) methods and immobilized artificial membrane (IAM) liquid chromatographic approaches were compared for a set of 45 solutes. MLC measurements were p...
In this study, micelles prepared from distearoylphosphatidylethanolamine with covalently attached poly(ethylene) glycol) (PEG) of molecular weight 2000 (DSPE-PEG-2000) were employed in micellar electrokinetic chromatography (MEKC) as pseudostationary phases. Since DSPE-PEG-2000 contains long hydrophobic alkyl chains, an anionic phosphate group, and hydrophilic PEG chains, the prepared micelles ...
