Despite recent advances in cancer therapy, many malignant tumors still lack effective treatment and the prognosis is very poor. Paclitaxel is a potential anticancer drug, but its use is limited by the facts that paclitaxel is a P-gp substrate and its aqueous solubility is poor. In this study, three-step tumor targeting of paclitaxel using biotinylated(More)
The aim of the study was to develop enzyme sensitive polymers for pharmaceutical applications. Thus, 2,2'-bis(2-oxazoline)-linked poly-epsilon-caprolactone (PCL-O) polymers were synthesized by using epsilon-caprolactone precursors with different molecular weights (M(n): 1500, 3900, 7500 and 12,000g/mol), and the effects of PCL block length on enzymatic(More)
Previously, we have demonstrated that 2,2-bis(2-oxazoline) linked poly-epsilon-caprolactone (PCL-O) is degraded in vitro enzymatically by surface erosion which could enable the novel use of this material for drug delivery and other biomedical applications. In this study, degradation, erosion (weight loss) and toxicity of PCL-O poly(ester-amide)s were(More)
This paper presents an advanced self balancing bridge accelerometer with closed loop digital feedback using the sigma delta-chip. Self-balancing bridge reduces the squeeze film damping by introducing the holes in the structure as add on to the proposed structure. The total area of the electrodes is 7. 44*10-6 as compared to the total area of the holes which(More)
