The association between Clonorchis sinensis seropositivity and hepatocellular carcinoma in an endemic area: a study in Guangxi, China.

Background: Chronic infection with Clonorchis sinensis (C.sinensis) has been associated swith the development of intrahepatic cholangiocarcinoma (ICC); however, the relationship between C.sinensis and hepatocellular carcinoma (HCC) remains uncertain.

[Chemical constituents from fruiting bodies of Tremella sanguinea].

The chemical constituents from the fruiting bodies of Tremella sanguinea were separated and purified by column chromatography on silica gel,ODS,Sephadex LH-20,and RP-HPLC. The structures of the isolated compounds were identified on the basis of physicochemical properties and spectroscopic data analysis,as well as comparisons with the data reported in the literature. Sixteen compounds were isolated from the 90% ethanol extract of the fruiting bodies of T.

Quantification of microRNA by gold nanoparticle probes.

MicroRNAs are important posttranscriptional regulators of gene expression in animals and plants. A sensitive and specific detection method is urgently needed for intensive studies on differential expression and regulatory roles of microRNA. Here we present a simple and reliable method for the quantification of microRNA.
