The article offers information on a study on efficacy and tolerability of drug clopidogrel napadisilate in coronary stenting patients of Korea. It mentions that clopidogrel napadisilate is not inferior to clopidogrel bisulfate in anti-platelet efficacy and mentions that it showed no adverse events. It mentions that the drug can be used in patients with percutaneous coronary intervention with drug-eluting stent (DES).

The spontaneous polarization and electro-optic response of ferroelectric liquid crystals (FLCs) were investigated in a cell fabricated with a polyimide alignment layer coated by the Langmuir-Blodgett method. The surface properties of the cured polyimide layers were monitored by contact angle measurement, and by FTIR spectroscopy and AFM for the orientation and surface roughness, respectively. The apparent spontaneous polarization of an FLC determined in a practical sandwich-cell depended on various conditions such as cell thickness, cooling rate from the smectic A to chiral smectic C phase, and deposition pressure. Electro-optic response and decay times of FLCs were also measured. Furthermore, the ions in the FLC mixture reduced the magnitude of the effective electric field, but had no effect at high frequency.
