Low-dose methotrexate (MTX), a traditional folate antagonist and disease-modifying antirheumatic drug administered weekly either alone or as combination therapy, is widely accepted as the gold standard in rheumatoid arthritis (RA) treatment. Although its mechanism of action in RA is still poorly understood, MTX potentially acts via antiproliferative,(More)
Use of multiplex real-time reverse transcription polymerase chain reaction (RT-PCR) for the simultaneous detection of influenza type B virus and influenza A virus subtypes H5N1, H3N2, and H1N1 has been described. The method exhibited a high specificity and sensitivity of approximately 101–102 copies per microliter or 10−3–10−2 TCID50/L for each subtype, as(More)
Three new compounds of Ga(III), Au(III), Sn(IV) with matrine (MT), [H-MT][GaCl(4)] (1), [H-MT][AuCl(4)] (2) and [Sn(H-MT)Cl(5)] (3), have been synthesized and characterized by elemental analysis, IR, ESI-MS and single crystal X-ray diffraction methods. The crystal structural analyses indicate that 1 and 2 are ionic compounds, whereas 3 is a tin(IV) complex(More)
We report the imaging of hepatocellular carcinoma cells and the immunoassay for alpha fetoprotein (AFP) using CdTe/CdS/ZnS core-shell-shell QDs. Stable and high PLQY (20%-48%) CdTe/CdS/ZnS core-shell-shell QDs were synthesized by a stepwise process. Bioconjugation of the core-shell-shell QDs with streptavidin (SA) was successfully applied in(More)
Liriodenine (L), a natural alkaloid, was isolated as an active component from the anticancer traditional Chinese medicine (TCM), Zanthoxylum nitidum. It reacted with Mn(II), Fe(II), Co(II) and Zn(II) to afford four metal complexes: [MnCl(2)(L)(2)] (1), [FeCl(2)(L)(2)] (2), [Co(L)(2)(H(2)O)(2).Co(L)(2)(CH(3)CH(2)OH)(2)](ClO(4))(4) (3), and(More)
Liriodenine, an oxoaporphine alkaloid with anticancer activity isolated from Zanthoxylum nitidum (rutaceous anticancer traditional Chinese medicine), was selected as a bioactive ligand to react with HAuCl4 and NaAuCl4 to afford [LH][AuCl4] (1) and [AuCl3L] (2), respectively (where L is liriodenine). The structures of 1 and 2 were characterized by IR(More)
The alkaloid oxoglaucine (OG), which is a bioactive component from traditional Chinese medicine (TCM), was synthesized by a two-step reaction and used as the ligand to react with transition metal salts to give four complexes: [OGH][AuCl(4)]·DMSO (1), [Zn(OG)(2)(H(2)O)(2)](NO(3))(2) (2), [Co(OG)(2)(H(2)O)(2)](ClO(4))(2) (3), and(More)
OBJECTIVE To investigate the anti-proliferative effects of curcumol, an herbal extract from curcuma, in human hepatocarcinoma HepG2 cells, and its possible molecular mechanism. METHOD The effects of curcumol on human hepatocarcinoma cells were assessed in vitro. Proliferation of HepG2 cells treated with various concentration (2.5-10 mg x L(-1)) of(More)
Three new lanthanide complexes with dihalo-substituted 8-quinolinol: [Gd(BrQ)(3)(H(2)O)(2)]·1.33EtOH·0.33H(2)O (1), [Dy(ClQ)(3)(H(2)O)(2)]·1.33EtOH·0.33H(2)O (2), [Er(ClQ)(3)(H(2)O)(2)]·1.33EtOH·0.33H(2)O (3) (H-BrQ = 5,7-dibromo-8-quinolinol, H-ClQ = 5,7-dichloro-8-quinolinol) have been synthesized and characterized by elemental analysis, IR, ESI-MS,(More)
A novel and portable strategy based on fluorescence polarization immunoassay (FPIA) using quantum dots (QDs) was described in this study for simple, rapid, and sensitive detection of carcinoembryonic antigen (CEA). Under optimal conditions, the sensor has a wide dynamic range (from 0.5 ng/mL to 200 ng/mL) and a good correlation. The limit of detection (LOD)(More)
