Previous studies demonstrated that the rewarding effect of psychostimulants, such as amphetamine and cocaine, can be predicted by locomotor activity toward novelty in a free-choice situation but not motor response developed in inescapable environment. However, whether this relationship also exists with narcotic morphine remains unclear. In the present(More)
Hepatocellular carcinoma (HCC) dual targeted stimuli responsive nanoparticles (NPs) for intracellular delivery of doxorubicin (DOX) were developed based on a reduction cleavable hyaluronic acid-glycyrrhetinic acid conjugate (HA-Cyst-GA). HA-Cyst-GA conjugate readily formed NPs in aqueous milieu and exhibited a high drug loading capacity (33.9%). The NPs(More)
Tuberculosis (TB) is a serious disease that is characterized by Mycobacterium tuberculosis (M.tb)-triggered immune system impairment and lung tissue damage shows limited treatment options. MicroRNAs (miRNAs) are regulators of gene expression that play critical roles in many human diseases, and can be up- or downregulated by M.tb infection in macrophage.(More)
The objective of this study was to develop a suitable formulation for baicalein (a poorly water-soluble drug exhibiting high melting point) to prepare solid dispersions using hot melt extrusion (HME). Proper carriers and plasticizers were selected by calculating the Hansen solubility parameters, evaluating melting processing condition, and measuring the(More)
Pathological levels of homocysteine induce a dramatic degradation of arterial elastic structures. This severe metalloproteinase-dependant elastolysis affects elastic structures all over the media suggesting that smooth muscle cells (SMC) may participate to this process induced by homocysteine. Therefore, we investigated the effect of physiological (10 μM)(More)
Tumor metastasis is the biggest challenge in cancer therapy. During the metastasis process, metastatic cells could acquire stealth ability toward immune system through the formation of a protection cloak by hijacking platelets (PTs). Heparins, a heterogeneous mixture of glycosaminoglycans, can inhibit metastatic cascades by blocking P-selectin-mediated(More)
This work aimed to improve the oral bioavailability and plasma lipid-lowering effect of probucol (PB) by constructing a combined drug delivery system (CDDS) composed of nanostructured lipid carrier (NLC) and PEGylated poly(amidoamine) dendrimer (PEG-PAMAM). PEG-PAMAM with dendrimer generations of 5 (G5-PEG) or 7 (G7-PEG) were incorporated in PB-NLCs to form(More)
BACKGROUND Clinical needs often dictate testing for several autoantibodies in a single patient with evidence of autoimmune disease. We developed a microarray containing 15 autoantigens for the detection of autoantibodies in rheumatoid autoimmune diseases. METHODS We synthesized recombinant centromere protein B, cytokeratin 19, SSA 52-kDa antigen, SSA(More)
OBJECTIVE The aim of this study was to characterize the microstructure of microemulsion consisting of oleic acid, Cremophor RH40, ethanol, and water (K(m) = 2), and investigate the influence of microstructure on the solubilization potential of the microemulsion to meloxicam (MLX). METHODS Pseudo-ternary phase diagrams of microemulsion were constructed(More)
PURPOSE Anti-tumor performance of docetaxel liposomes surface-modified with glycyrrhetinic acid (GA-DX-Lip) as a new hepatocytes-targeted delivery vehicle was investigated, unmodified docetaxel liposome (DX-Lip) was chosen as a comparison. METHODS GA-DX-Lip was prepared by film dispersion method. The physicochemical properties were characterized. The(More)
