Aberrant expression and activation of EGF receptor (EGFR) has been implicated in the development and progression of many human cancers. As such, targeted therapeutic inhibition of EGFR, for example by antibodies, is a promising anticancer strategy. The overall efficacy of antibody therapies results from the complex interplay between affinity, valence, tumor(More)
Gallbladder cancer (GBC) is one leading cause of cancer-related death worldwide. WW domain-containing oxidoreductase (WWOX) is a tumor suppressor gene which can suppress proliferation of a variety of tumors. However, little was known about the relationships between WWOX and gallbladder cancer. In the current study, we intended to investigate the tumor(More)
PURPOSE The aim of this report was to introduce a novel "core-membrane" microgel drug-delivery device for spontaneously pulsed release without any external trigger. METHODS The microgel core was prepared with alginate and chitosan. The semipermeable membrane outside the microgel was made of polyelectrolytes including polycation poly(allylamine(More)
A subcutaneous exenatide delivery system was developed and characterized in vitro and in vivo. The results clearly showed that the exenatide loaded PLGA microspheres prepared by using a non-aqueous processing medium had low burst release and high drug encapsulation efficiency. Exenatide loaded in the microspheres preserved its bioactivity. The(More)
pH-sensitive liposomes represent an effective gene vector in cancer therapy. However, their use is greatly hampered by their relatively low transfection efficiency. To improve the transfection efficiency of pH-sensitive liposomes, we prepared complexes containing 3β-[N-(N',N'-dimethylaminoethane) carbamoyl] cholesterol (DC-Chol) and dioleoylphosphatidyl(More)
Porcine parvovirus (PPV) can cause reproductive failure in swine, resulting in economic losses to the industry. Antiviral effects of diammonium glycyrrhizinate (DG) have been reported on several animal viruses; however, to date it has yet to be tested on PPV. In this study, the antiviral activity of DG on swine testis (ST) cell infection by PPV was(More)
Antibodies are ubiquitous and essential reagents for biomedical research. Uses of antibodies include quantifying proteins, identifying the temporal and spatial pattern of expression in cells and tissue, and determining how proteins function under normal or pathological conditions. Specific antibodies are only available for a small portion of the proteome,(More)
Single-port laparoscopic technology is effective in minimally invasive surgery. However, this technology requires expensive instrumentation. In the present study, an alternative minimally invasive technique, periumbilical laparoscopic surgery through triple channels using common instrumenta-tion, is introduced. Increased use of this new technique may be(More)
Due to the impermeability of the blood-brain barrier and the nonselective distribution of drugs in the brain, the therapeutic access to intractable neurological disorders is challenging. In this study, dual brain-targeting polymersomes (POs) functionalized by transferrin and Tet-1 peptide (Tf/Tet-1-POs) promoted the transportation of curcumin into the brain(More)
