Optimization of Weight Ratio for DSPE-PEG/TPGS Hybrid Micelles to Improve Drug Retention and Tumor Penetration

Pharmaceutical Research, 2018
To enhance therapeutic efficacy and prevent phlebitis caused by Asulacrine (ASL) precipitation post intravenous injection, ASL-loaded hybrid micelles with size below 40 nm were developed to improve drug retention and tumor penetration.ASL-micelles were prepared using different weight ratios of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine ...

Effects of the nanofiller size and aspect ratio on the thermal and rheological behavior of PEG nanocomposites containing boehmites or hydrotalcites

Journal of Thermal Analysis and Calorimetry, 2018
In this work, polyethylene glycol nanocomposites containing different nanofillers (namely hydrotalcites or boehmites, at 5 mass% loading) were prepared by melt compounding. Their morphology and microstructure were assessed by means of SEM and XRD analyses.

Evidence for an altered sex ratio in clinic-referred adolescents with gender dysphoria.

Journal of Sexual Medicine, 2015
INTRODUCTION The number of adolescents referred to specialized gender identity clinics for gender dysphoria appears to be increasing and there also appears to be a corresponding shift in the sex ratio, from one favoring natal males to one favoring natal ...

Single Force-Guided Precision Peg-in-Hole Search of Cylindrical Part with Small Length/Diameter Ratio

2018 IEEE 8th Annual International Conference on CYBER Technology in Automation, Control, and Intelligent Systems (CYBER), 2018
This paper presents an approach to deal with precise positioning for valve spool of precision solenoid valve in automatic assembly. The valve spool is the cylindrical part with length/diameter ratio less than 0.3 and the mating clearance is narrower. At present, its assembly process is positioning first and then inserting.
