Determination of oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine products in human very low-density lipoproteins by nonaqueous low-flow capillary electrophoresis-mass spectrometry.

A simple and fast low-flow capillary electrophoresis-mass spectrometry (low-flow CE-MS) method has been developed to analyze oxidized 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphocholine (ox-PAPC) products in human very low-density lipoproteins (VLDLs). Native PAPC standard was analyzed to optimize the low-flow CE-MS method. The optimal CE conditions included separation buffer (60% (v/v) acetonitrile, 40% (v/v) methanol, 0.

Evaluation of skeletal and dentoalveolar changes in class II division I pediatric patients receiving myofunctional appliance therapy: A preliminary study.

Background/purpose: The treatment effect of myofunctional appliance therapy has remained debated. The aim of this study was to evaluate the skeletal and dentoalveolar effects in class II division I pediatric patients receiving Education Fonctionnelle (EF) myofunctional appliance therapy.

Methods: Thirteen patients undergoing EF appliance treatment (9 boys and 4 girls；average 9.

Cyclodextrin-micellar electrokinetic chromatography of apolipoproteins on human very low-density lipoprotein.

The apolipoproteins (APOs) of human very low-density lipoprotein (VLDL) were investigated by an optimized cyclodextrin-micellar electrokinetic chromatography (CD-MEKC) method. The separation buffer consisted of 20 mM sodium phosphate, 40 mM bile salts (50% sodium cholate and 50% sodium deoxycholate), 25 mM carboxymethyl-β-cyclodextrin (CM-β-CD) (pH 7.0).
