Digital TV offers of 200 channels and 500 video-on-demand films, podcasting, mobile television, a new web blog being created every two seconds - these are some of the factual elements depicting contemporary audiovisual media in the digital environment. The present article looks into some of these technological advances and sketches their implications for the markets of media content, in particular as newly emerging patterns of consumer and business behaviour are concerned. Ultimately, it puts forward the question of whether the existing audiovisual media regulatory models, which are still predominantly analogue-based, have been rendered obsolete by the transformed (and continually transforming) digital environment.

In the profoundly changing and dynamic world of contemporary audiovisual media, what has remained surprisingly unaffected is regulation. In the European Union, the new Audiovisual Media Services Directive (AVMS), proposed by the European Commission on December 13, 2005, should allegedly rectify this situation. Amending the existing Television without Frontiers Directive, it should offer a fresh approach and meet the challenge of appropriately regulating media in a complex environment. It is meant to achieve a balance between the free circulation of TV broadcast and new audiovisual media and the preservation of values of cultural identity and diversity, while respecting the principles of subsidiarity and proportionality inherent to the Community. The purpose of this paper is to examine whether and how the changes envisaged to the EC audiovisual media regime might influence cultural diversity in Europe. It addresses subsequently the question of whether the new AVMS properly safeguards the balance between competition and the public interest in this regard, or whether cultural diversity remains a mere political banner.

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.

BACKGROUND: Marfan syndrome (MFS) is a heritable disorder of connective tissue, affecting principally skeletal, ocular, and cardiovascular systems. The most life-threatening manifestations are aortic aneurysm and dissection. We investigated changes in the proteome of aortic media in patients with and without MFS to gain insight into molecular mechanisms leading to aortic dilatation. METHODS AND RESULTS: Aortic samples were collected from 46 patients. Twenty-two patients suffered from MFS, 9 patients had bicuspid aortic valve, and 15 patients without connective tissue disorder served as controls. Aortic media was isolated and its proteome was analyzed in 12 patients with the use of 2-dimensional difference gel electrophoresis and mass spectrometry. We found higher amounts of filamin A C-terminal fragment, calponin 1, vinculin, microfibril-associated glycoprotein 4, and myosin-10 heavy chain in aortic media of MFS aneurysm samples than in controls. Regulation of filamin A C-terminal fragmentation was validated in all patient samples by immunoblotting. Cleavage of filamin A and the calpain substrate spectrin was increased in the MFS and bicuspid aortic valve groups. Extent of cleavage correlated positively with calpain 2 expression and negatively with the expression of its endogenous inhibitor calpastatin. CONCLUSIONS: Our observation demonstrates for the first time upregulation of the C-terminal fragment of filamin A in dilated aortic media of MFS and bicuspid aortic valve patients. In addition, our results present evidence that the cleavage of filamin A is highly likely the result of the protease calpain. Increased calpain activity might explain, at least in part, histological alterations in dilated aorta.

Cultural protectionism has been an element of national and foreign policies, as an extension of state sovereignty expressed both in a defensive and offensive manner. While the generic protectionist formula in the sense of restraining trade between states through measures such as import tariffs or quotas and through privileging domestic production has somewhat disintegrated over time under the rationale for free trade and the strong practical evidence of its benefits, the particular case of cultural protectionism has persevered. As we reveal in this paper, however, it has been modified, or at least its rhetoric has changed. The enquiry into the notion of cultural protectionism or cultural diversity, as the current political jargon would have it, is but one of the paper’s objectives. Its second and certainly more ambitious goal is the search for the normative dimensions of cultural diversity policies in the global digital space, asking what adjustments are needed and how feasible the entire project of diversity regulation in this environment may be. Taking into account the specificities of cyberspace and in a forward-looking manner, we propose some adjustments to current media policy practices that could better serve the goal of a sustainably diverse cultural environment.

Irrespective of the diverse stances taken on the effect of the UNESCO Convention on Cultural Diversity in the external relations context, since its wording is fairly open-ended, it is clear to all observers that the Convention’s impact will largely depend on how it is implemented domestically. The discussion on the national implementation of the Convention, both in the policy and in the academic discourses, is only just emerging. The implementation model of the EU could set an important example for the international community and for the other State Parties that have ratified the UNESCO Convention, as both the EU and its Member States acting individually, have played a critical role in the adoption of the Convention, as well as in the longer process of promoting cultural concerns on the international scene. Against this backdrop, this article analyses the extent to which the EU internal law and policies, in particular in the key area of media, take into account the spirit and the letter of the UNESCO Convention on Cultural Diversity. The article seeks to critically evaluate the present state of affairs and make some recommendations for calibration of future policies.

Assisted reproductive technologies (ART) induce vascular dysfunction in humans and mice. In mice, ART-induced vascular dysfunction is related to epigenetic alteration of the endothelial nitric oxide synthase (eNOS) gene, resulting in decreased vascular eNOS expression and nitrite/nitrate synthesis. Melatonin is involved in epigenetic regulation, and its administration to sterile women improves the success rate of ART. We hypothesized that addition of melatonin to culture media may prevent ART-induced epigenetic and cardiovascular alterations in mice. We, therefore, assessed mesenteric-artery responses to acetylcholine and arterial blood pressure, together with DNA methylation of the eNOS gene promoter in vascular tissue and nitric oxide plasma concentration in 12-wk-old ART mice generated with and without addition of melatonin to culture media and in control mice. As expected, acetylcholine-induced mesenteric-artery dilation was impaired (P = 0.008 vs. control) and mean arterial blood pressure increased (109.5 ± 3.8 vs. 104.0 ± 4.7 mmHg, P = 0.002, ART vs. control) in ART compared with control mice. These alterations were associated with altered DNA methylation of the eNOS gene promoter (P < 0.001 vs. control) and decreased plasma nitric oxide concentration (10.1 ± 11.1 vs. 29.5 ± 8.0 μM) (P < 0.001 ART vs. control). Addition of melatonin (10(-6) M) to culture media prevented eNOS dysmethylation (P = 0.005, vs. ART + vehicle), normalized nitric oxide plasma concentration (23.1 ± 14.6 μM, P = 0.002 vs. ART + vehicle) and mesentery-artery responsiveness to acetylcholine (P < 0.008 vs. ART + vehicle), and prevented arterial hypertension (104.6 ± 3.4 mmHg, P < 0.003 vs. ART + vehicle). These findings provide proof of principle that modification of culture media prevents ART-induced vascular dysfunction. We speculate that this approach will also allow preventing ART-induced premature atherosclerosis in humans.

This paper begins to address the international regulation of emerging technologies taking an approach that includes the co-production of technologies and the nature of wicked problems. Both the development of technologies over time, the role of science in regulation, and results from case studies in the regulation of biotechnologies are discusses. Biotechnology, nanotechnology and synthetic biology receive the most attention.

Constructing an original panel on Maximum Residue Levels (MRLs) in pesticides for 50 countries over 2006-2012, this paper studies the effect of heterogeneity in MRL regulation on bilateral trade. We find evidence of regulatory heterogeneity diminishing trade at the extensive margin when the exporter faces more stringent regulation abroad, suggesting compliance costs in entering the destination market. Significantly, however, we also find strong evidence of regulatory heterogeneity increasing trade at the intensive margin for exports coming from countries that set the strictest standards, alluding to the positive informative effect of such regulation.
