A superparamagnetic reduced graphene oxide-Fe(3)O(4) hybrid composite (rGO-Fe(3)O(4)) was prepared via a facile and straightforward method through the solvothermal reaction of iron (III) acetylacetonate (Fe(acac)(3)) and graphene oxide (GO) in ethylenediamine (EDA) and water. By this method, chemical reduction of GO as well as the formation of Fe(3)O(4)(More)
We report that ultra-small, monodisperse, water-dispersible magnetite (Fe(3)O(4)) nanoparticles can be synthesized by a facile one-pot approach using trisodium citrate as crystal grain growth inhibitor and stabilizer in polyol solution. The resultant Fe(3)O(4) nanoparticles exhibit an excellent long-term colloidal stability in various buffer solutions(More)
OBJECTIVE To detect the level of serum and liver tissue TGF-beta1 in patients with chronic hepatitis B, to study their relation to liver fibrosis and gain the evidence for diagnosis of liver fibrosis. METHODS The liver fibrosis grades (S0-S4) of 131 cases with chronic HBV infection were diagnosed after liver biopsy. Serum TGF-beta1 was detected by(More)
OBJECTIVE To study the impact of IFN-gamma on liver fibrosis and its possible mechanism. Thirty healthy male SD rats were randomly divided into two groups: fibrosis model group, IFN-gamma treatment group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4. After 12-week-treatment, serum hyalurnic acid and TGF-beta1 was examined,(More)
OBJECTIVE To investigate the dynamic expression of TGF-beta1/Smad protein in rats with liver fibrosis induced by carbon tetrachloride (CCl4), to study mechanism of TGF-beta1/Smad signaling and the relationship between its transduction and liver fibrosis. METHODS Fifty healthy male SD rats were randomly divided into two groups: normal control group and(More)
