Polyelectrolyte complex films were prepared with polyethyleneoxide-maleic acid copolymer and chitosan using a casting/solvent evaporation method. The films were examined in terms of their IR spectra, surface and cross-section morphologies, cytotoxicity, and swelling behavior at different pH levels. To assess the potential of these films as a biomedical device, the profiles of the release of model drug from the CS/PEOMA films were examined at pH 4.8. The surface morphology of the films was quite smooth and uniform, and the cross-sectional morphology was dense and homogeneous. The swelling behaviors of CS/PEOMA films were found to depend on the pH of the solution as well as on the CS/PEOMA composition. Drug release from different CS/PEOMA films at pH 4.8 was found to be dependent on film composition. The results showed the potential applicability of CS/PEOMA film as a drug delivery vehicle.
This article shows that anti-essentialism was a pivotal ideological feature of Russian Zionism-the idiom of Zionism that lay behind Russian Zionist periodicals such as Rassvet in Late Imperial Russia. For Russian Zionists, the Jewish nation was the social field that existed as a social fact. While Russian Zionists' concept of the Jewish nation was inevitably influenced by their political context, nonetheless, it was primarily a result of the convergence of the following two ideological movements. First, there emerged a sense that a socioeconomic foundation was crucial in forming a nation. The transformation of Jewish socioeconomic positions in Eastern Europe and Russia was the background of this consciousness. The second is the ideological claim that any collective entity or social field should be respected regardless of its merit and utility visa -vis others. More specifically, for Russian Zionists, the Jewish raison d' etre was the simple existence of their own social field; they believed that no further definition was required. The emergence of this viewpoint can be understood as a reaction to the Zionists' perception of Jewish history where Jews pursued the recognition and validation of their place among non-Jews by virtue of their merit or utility visa -vis non-Jews.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
