Tissue-type plasminogen activator (t-PA) is a widely used thrombolytic agent for treating acute myocardial infarction. Some previous studies suggest that t-PA benefits the heart independently of lysing coronary artery thrombi. The purpose of this study was to determine whether t-PA directly affects infarct size independently of lysing coronary thrombi, affects the no-reflow phenomenon, and exac...

A new micromachined cell lysis device is developed. It is designed for miniature bio-analysis systems where cell lysing is needed to obtain intracellular materials for further analysis such as DNA identification. It consists of muti-electrode pairs to apply electric fields to cells. We adopt the means of using electric field lysing because it can greatly simplify purification steps for preparat...

The FastPrep-24 5G (Fig. 1) is a high-speed, benchtop reciprocating instrument that is intended for the optimal lysis of challenging and routine sample types. Its use of bead-beating technology makes it suitable in all applications that require grinding, lysing or homogenization of various solid sample materials. Mechanical sample lysis offers rapid sample preparation for the isolation of DNA, ...

Alga-lysing bacteria have been paid much attention to in recent years. In this study, the alga-lysing strain P05 which was isolated from an immobilizing biosystem was immobilized by coke and elastic filler, forming two biological reactors. The removal efficiencies of algae, NH4(+)-N and organic matter using the two reactors were studied. The results showed that strain P05 was an ideal algal-lys...

Current clinically approved thrombolytic agents have significant drawbacks including reocclusion and bleeding complications. To address these problems, a staphylokinase-based thrombolytic agent equipped with antithrombotic activity from hirudin was engineered. Because the N termini for both staphylokinase and hirudin are required for their activities, a Y-shaped molecule is generated using engi...

To avoid the adverse effects of aprotinin (Apr) in autologous fibrin glue, we compared the inhibitory properties of four commercial anti-fibrinolytic agents (tranexamic acid (Tra), epsilon-aminocaproic acid (Ips), gabexate mesilate (Gab) and nafamostat mesilate (Naf)). The optimum conditions for the lysing of fibrin glue were an incubation temperature of 37 degrees C, and incubation medium cont...
