Controlling New Media (without the Law)

The purpose of this paper is to explore some emerging modes of control that are evolving wholly or partially outside conventional media law. We focus in particular on the entirely novel mechanisms of control enabled through code and technology in general. We compare these new models with traditional regulatory bodies and their decision-making processes and, making reference to the values and interests that are embedded in the design of mediating technologies, ask whether the new tools of control are appropriate for achieving public policy objectives in a complex new-and-old media landscape, or whether in fact they introduce some dangers.

The New Audiovisual Media Services Directive : Television without Frontiers, Television without Cultural Diversity

After long deliberations, the European Community (EC) has completed the reform of its audiovisual media regulation. The paper examines the main tenets of this reform with particular focus on its implications for the diversity of cultural expressions in the European media landscape. It also takes into account the changed patterns of consumer and business behaviour due to the advances in digital media and their wider spread in society. The paper criticises the somewhat unimaginative approach of the EC to new media and the political (and at times protectionist) considerations behind some of the Directive's provisions.

Short- and long-term cultivation of embryonic and neonatal murine keratinocytes

Studies using cultured cells allow one to dissect complex cellular mechanisms in greater detail than when studying living organisms alone. However, before cultured cells can deliver meaningful results they must accurately represent the in vivo situation. Over the last three to four decades considerable effort has been devoted to the development of culture media which improve in vitro growth and modeling accuracy. In contrast to earlier large-scale, non-specific screening of factors, in recent years the development of such media has relied increasingly on a deeper understanding of the cell's biology and the selection of growth factors to specifically activate known biological processes. These new media now enable equal or better cell isolation and growth, using significantly simpler and less labor-intensive methodologies. Here we describe a simple method to isolate and cultivate epidermal keratinocytes from embryonic or neonatal skin on uncoated plastic using a medium specifically designed to retain epidermal keratinocyte progenitors in an undifferentiated state for improved isolation and proliferation and an alternative medium to support terminal differentiation.

Governance of Digital Game Environments and Cultural Diversity : Transdisciplinary Enquiries

Digital game environments are of increasing economic, social and cultural value. As their influence on diverse facets of life grows, states have felt compelled to intervene and secure some public interests. Yet, the contours of a comprehensive governance model are far from recognisable and governments are grappling with the complexity and fluidity of online games and virtual worlds as private spaces and as experimentation fields for creativity and innovation. This book contributes to a more comprehensive and fine-grained understanding of digital game environments, which is a precondition for addressing any of the pressing governance questions posed. Particular attention is given to the concept and policy objective of cultural diversity, which also offers a unique entry point into the discussion of the appropriate legal regulation of digital games. Governance of Digital Game Environments and Cultural Diversity will be of interest to researchers of media law, internet law and governance, cultural studies, anthropology and sociology. As the book addresses a highly topical theme, it will attract the attention of policymakers at national, regional and international levels and will also serve as a great resource tool for scholars in new media and, in particular, digital games and virtual worlds.

Development of Drugs Targeting the PI3K Signalling Pathway in Leukaemias and Lymphomas

The phosphoinositide 3-kinase (PI3K) family of signalling enzymes play a key role in the transduction of signals from activated cell surface receptors controlling cell growth and proliferation, survival, metabolism, and migration. The intracellular signalling pathway from activated receptors to PI3K and its downstream targets v-akt murine thymoma viral oncogene homolog (Akt) and mechanistic target of rapamycin (mTOR) is very frequently deregulated by genetic and epigenetic mechanisms in human cancer, including leukaemia and lymphoma. In the past decade, an arsenal of small molecule inhibitors of key enzymes in this pathway has been developed and evaluated in pre-clinical studies and clinical trials in cancer patients. These include pharmacological inhibitors of Akt, mTOR, and PI3K, some of which are approved for the treatment of leukaemia and lymphoma. The PI3K family comprises eight different catalytic isoforms in humans, which have been subdivided into three classes. Class I PI3K isoforms have been extensively studied in the context of human cancer, and the isoforms p110α and p110δ are validated drug targets. The recent approval of a p110δ-specific PI3K inhibitor (idelalisib/Zydelig®) for the treatment of selected B cell malignancies represents the first success in developing these molecules into anti-cancer drugs. In addition to PI3K inhibitors, mTOR inhibitors are intensively studied in leukaemia and lymphoma, and temsirolimus (Torisel®) is approved for the treatment of a type of lymphoma. Based on these promising results it is hoped that additional novel PI3K pathway inhibitors will in the near future be further developed into new drugs for leukaemia and lymphoma.
