BACKGROUND Mesenchymal stem cells within the stromal-vascular fraction of subcutaneous adipose tissue, adipose-derived stem cells (ADSCs), produced soluble factors and they exhibit diverse pharmacological effects in skin biology. OBJECTIVE The present study examines the protective effect of ADSCs for human dermal fibroblasts (HDFs) through anti-oxidation(More)
A mixed micelle that comprised of MPEG-PLA (MPP) and Pluronic copolymers was developed for enhanced bioavailability and to overcome multidrug resistance of docetaxel in cancer therapy. The mixed micelles that sufficiently solubilized docetaxel were evaluated for the effect of Pluronic copolymers weight ratio on the mixed micelles with respect to drug(More)
In our previous study, lung tumor-specific targeting of paclitaxel was achieved in mice by intravenous administration of chitosan-modified paclitaxel-loaded PLGA nanoparticles (C-NPs-paclitaxel). Transient formation of aggregates in the blood stream followed by enhanced trapping in the capillaries was proposed as a mechanism of the lung-specific(More)
The objective of this study was to examine the kinetics of the distribution of dehydroevodiamine (DHED) in the rat brain. After an intravenous infusion of 15 min (dose of 1-10 mg/kg), the temporal profiles of the plasma levels of DHED declined in a multiexponential manner. Moment analysis indicated that the clearance and steady-state volume of distribution(More)
A microemulsion system of docetaxel was prepared and evaluated for its solubilization capacity and oral bioavailability improvement. Based on a solubility study and pseudo ternary phase diagrams, microemulsions of about 30 nm in mean diameter were formulated with improved solubilization capacity towards the hydrophobic drug, docetaxel. The o/w microemulsion(More)
Ketoprofen plasters of 70 cm(2) size using DuroTak acrylic adhesive polymers were developed either containing 30 mg (Ketotop-L) or 60 mg drug (Ketotop-P). The in vitro skin permeation profile was obtained in hairless mouse skin and showed the permeation rate of Ketotop-P to be twice that of Ketotop-L. The plasma concentration profile of ketoprofen was(More)
The effect of sixteen excipients on the transport of recombinant human epidermal growth factor (rhEGF) across Caco-2 cell monolayers was examined at 37 degrees C. The apparent apical to basolateral (A-B) permeability (Papp) of 30 microM rhEGF was 8.15 x 10(-7) cm/sec, indicative of a poor level of absorption in the GI tract. The Papp was 1.7- and 6.3-fold(More)
Purpose. Taurine, a β-amino acid, is a neuromodulator which interacts functionally with the glycinergic, GABAergic, cholinergic and adrenergic systems. Although a continuous cell culture model is not available for the choroid plexus epithelia, we recently described a primary cell culture of rabbit choroid plexus epithelia. The goal of the current study was(More)
The effect of protein-calorie malnutrition (PCM) on the expression and functional activity of P-glycoprotein (P-gp) in the liver of rats was examined. Control protein diets and protein-restricted diets were fed to Sprague-Dawley rats for 4 weeks, and the expression of P-gp in the liver (Western blot), in vitro uptake of a representative substrate of P-gp,(More)
Although acute renal failure (ARF) has been an area of extensive research in recent decades, our understanding of ARF is far from complete. Organic cations (OCs) are primarily excreted via vectorial transport by various renal organic cation transporters (OCTs). It is reasonable to assume that ARF may alter the expression profiles of these transporters. In a(More)
