Electrochemical immunosensor with aptamer-based enzymatic amplification.

An electrochemical immunosensor is reported by using aptamer-based enzymatic amplification with immunoglobulin E (IgE) as the model analyte. In this method, the IgE antibody is covalently immobilized as the capture probe on the gold electrode via a self-assembled monolayer of cysteamine. After the target is captured, the biotinylated anti-IgE aptamer is used as the detection probe.

[Effect of tongxinluo ultramicro-pulverization on myocardial post-reperfusion no-reflow in mini-swine model of acute myocardial infarction].

Objective: To assess the effect of Tongxinluo (TXL) ultramicro-pulverization in preventing and treating post-reperfusion no-reflow in mini-swine model of acute myocardial infarction.

Methods: Forty mini-swines were randomly divided into 5 groups, the control group, the three (low-, middle- and high-dose) TXL groups and the sham-operation group, with 8 in each group. After pigs in the three TXL groups were administered with TXL in a dose of 0.
