The fate of a cell following stimulation by the prostanoid prostacyclin is cell specific, depending not only on the ability of prostacyclin to activate the cell surface prostacyclin(IP) receptor and regulate its coupling to various G proteins, but also on its ability to act intracellularly via the nuclear peroxisome proliferator-activated receptor family(PPAR). This review will highlight the different signalling options available to prostacyclin, and discuss the consequences for cell responses.

The last few decades have seen a phenomenal increase in the quality, diversity and pervasiveness of computer games. The worldwide computer games market is estimated to be worth around USD 21bn annually, and is predicted to continue to grow rapidly. This paper reviews some of the recent developments in applying computational intelligence （CI） methods to games, points out some of the potential pitfalls, and suggests some fruitful directions for future research.

Governments worldwide rightly regard universities as fundamental to the achievement of many national priorities. But it is the paper’s contention that many misunderstand their true benefit to society. Investments in universities are increasingly based on the belief that the science labs in particular of research-intensive universities can be the source of a continuous stream of people and ideas that will spawn innovative and fast growing companies to form the nexus of the knowledge-based economy. This belief is a source of misconceived policies that offer only ultimate disillusion. It is the totality of the university enterprise that is important, as the only place where that totality of ourselves and our world is brought together, and which makes it the strongest provider of the rational explanation and meaning that societies need. In research, universities create new possibilities; in teaching, they shape new people. Its graduates learn to seek the true meaning of things: to distinguish between the true and the merely seemingly true, to verify for themselves what is stable in that very unstable compound that often passes for knowledge. It is the complex, interacting whole of the university that is the source of the separate economic, social, cultural and utilitarian benefits valued by society. It needs to be understood, valued and managed as a whole. These perceptions are a direct challenge to not only to governments but to university administrators who have been either cowed or seduced into the slipshod thinking that is leading to demands that universities cannot satisfy, whilst obscuring their most important contributions. The challenge to both is to permit autonomy without oppressive accountability, and to give staff and students the freedom to think, speculate and research. These are the very conditions of the personal and collective creativity that are the sources of a university’s deepest benefits to its society.
