[Application of chemiluminescence immunoassay method in detection of serum index for liver fibrosis in patients with advanced schistosomiasis].

The method of chemiluminescence immunoassay (CLIA) was adopted to detect the levels of hyaluronic acid (HA), laminin (LN), III procollagen (CP III), IV collagen (IV-C) in the sera of 102 cases of advanced schistosomiasis. The results showed that the levels of the 4 indexes of advanced schistosomiasis patients were significantly higher than those of healthy people. It is suggested that the application of CLIA to detect the related serum indexes in patients with advanced schistosomiasis is useful in the diagnosis of liver fibrosis.

Dielectric properties and frequency response of self-assembled monolayers of alkanethiols.

This paper presents dielectric properties of alkanethiol self-assembled monolayers (SAMs) under an ac electric field. Using a Hg-SAM/SAM-Hg junction, we measured the ac impedance of alkanethiol SAMs using a sinusoidal perturbation of 30 mV (peak-to-peak) with frequency ranging from 1 Hz to 1 MHz at zero bias. Semicircles at higher frequencies and at middle frequencies along with Warburg lines at lower frequencies were observed in complex plane impedance plots, that is, Nyquist plots.
