Differentiation of embryonic and adult myogenic progenitors undergoes a complex series of cell rearrangements and specification events which are controlled by distinct gene regulatory networks. Delineation of the molecular mechanisms that regulate skeletal muscle specification and formation should be important for understanding congenital myopathies and(More)
This study is one of the first to test the relationship of formulation and structure of reconstituted high density lipoproteins (rHDL), drug behavior involved in remolding process and their targeting mechanism in a foam cell model. Tanshinone IIA-loaded rHDL (TA-rHDL) with different formulations and techniques were prepared and characterized. The targeting(More)
Novel Tanshinone II A (TA) ternary solid dispersion (tSD) pellets with the combination of polyvinylpyrrolidone and poloxamer 188 as dispersing carriers were prepared by a single-step technique. A formulation screening study showed that the addition of poloxamer 188 to binary TA-PVP system could remarkably promote the dissolution rate of TA from 60% to 100%(More)
To investigate the possibility of reconstituted protein-free high-density lipoprotein (HDL) being a carrier for delivering a lipophilic cardiovascular drug, Tanshinone IIA-loaded HDL-like nanostructured lipid carriers (TA-NLC) were prepared by a nanoprecipitation/solvent diffusion method. The physicochemical parameters of TA-NLC were characterized in terms(More)
The protein and mRNA expression of focal adhesion plaque associated cytoskeletons, including talin, vinculin, paxillin, and tensin, was studied using immunofluorescence in combination with confocal laser scanning microscopy and fluorescent quantitative polymerase chain reaction in 41 matched samples of human normal colorectal mucosae, primary colorectal(More)
Stealth tanshinone IIA-loaded solid lipid nanoparticles (TA-SSLNs) have been prepared and the influence of poloxamer 188 coating on in vitro phagocytosis and in vivo pharmacokinetics in rats were evaluated. TA-SSLNs have been prepared by a nanoprecipitation/solvent diffusion method. Poloxamer 188 was used as a stealth agent. The physicochemical parameters(More)
To compare blood glucose fluctuations in type 2 diabetes mellitus (T2DM) patients were treated using three procedures: insulin intensive therapy which is continuous subcutaneous insulin infusion (CSII), MDI3 (three injections daily), and MDI4 (four injections daily). T2DM patients were hospitalized and were randomly assigned to CSII, aspart 30-based MDI3,(More)
This study investigated phospholipids complex (PC) loaded pellets of poorly permeable Salvianolic acid B (SalB), in which PC was to improve the liposolubility and permeability of SalB. Transmission electron microscopy observation, differential scanning calorimetry measurement, infrared spectroscopy analysis, n-octanol/water partition coefficient study, and(More)
BACKGROUND Dayu County, which is located in southwestern Jiangxi Province in China, has been a cadmium (Cd)-contaminated area since the 1960s. A series of studies about Cd pollution were carried out in the 1980s. However, no further studies of the area were conducted during the following 19 years. AIM To observe cadmium (Cd) exposure levels and its health(More)
