This study describes the preparation and characterization of poly(lactic-co-glycolic acid) microspheres containing a novel anticancer agent, taxol (namely, Taxol-PLGA-MS). A solvent evaporation technique was utilized to prepare Taxol-PLGA-MS. The trapping efficiency of taxol in the microspheres was greater than 90% and reproducible. The in vitro release(More)
A 1.5Mpixel RGBZ image sensor that simultaneously captures color (RGB) and time-of-flight (ToF) range (Z) images is presented. While ToF sensors are well documented [1,2], few, if any, monolithic sensors have been reported that capture both range and color. In one sensor [3], a combined pixel structure captures color and range, but presumably in sequential(More)
This study describes an orthogonal experimental design to optimize the formulation of cisplatin (CDDP)-loaded chitosan microspheres (namely, CDDP-DAC-MS) which were produced by an emulsion-chemical cross-linking technique. Seven factors and three levels for each factor that might affect the formulation of microspheres were selected and arranged in an(More)
We developed a package of macro programs (named PK_MOMENT) to automatically calculate non-compartmental pharmacokinetic parameters on Microsoft Excel spreadsheets. These macros include rigorous algorithms to execute moment calculations in a comprehensive manner. An optimum number of terminal data points for infinite-time extrapolation can be calculated with(More)
This study describes the pharmacokinetic behaviours of taxol after intravenous administration of taxol-loaded poly(lactic-co-glycolic acid) microspheres containing isopropyl myristate (namely, Taxol-IPM-PLGA-MS) and taxol saline solution to mice. Taxol-IPM-PLGA-MS were prepared using a solvent evaporation technique. The drug content and trapping efficiency(More)
A highly compact ambient-light-cancellation (ALC) circuit for 3D time-of-flight (ToF) image sensor pixels is presented. It is implemented in a 320x240 pixel (QVGA) sensor with 14um pixel pitch in a 90 nm backside illumination (BSI) image sensor process. The ALC circuit has less than 3% fill factor impact and is very suitable for scaling to smaller pixels.(More)
