  • Dissemination is the purposive distribution of information and intervention materials to a specific public health or clinical practice audience. The intent is to spread information and the associated evidence-based interventions. Research on dissemination addresses how information about health promotion and care interventions is created, packaged,

  • Abstract While there have been many reports investigating the biological activity and signaling mechanisms of isoprostanes, their role in biology, particularly in platelets, appears to still be underestimated. Moreover, whether these lipids have their own receptors is still debated, despite multiple reports that discrete receptors for isporpstanes do exist on platelets, vascular tissues, amongst others.

  • Consider it as a shot across the bow. Republicans on the US House Committee on Science, Space, and Technology managed to include language in last month’s agreement for fiscal 2011 that stops the National Oceanic and Atmospheric Administration (NOAA) from spending on a new National Climate Service. The temporary restriction has little immediate impact, given that NOAA proposed how to create the service in its 2012 budget request, which is currently up for debate.

  • Whether dimerization is a general regulatory mechanism of receptor protein-tyrosine phosphatases (RPTPs) is a subject of debate. Biochemical evidence demonstrates that RPTPaand cluster of differentiation (CD)45 dimerize.

  • The mechanism behind the growth-promoting effect of insulin is a subject of debate. Employing RT4 bladder cancer cells, we examined the cross-talk between insulin and the epidermal growth factor system. We found that insulin induced a time- and dose-dependent (25–1000 nmolÆL )1 insulin) increase in mRNA expression of three ligands from the epidermal growth factor system.

  • The transmembrane topology of presenilins is still the subject of debate despite many experimental topology studies using antibodies or gene fusions. The results from these studies are partly contradictory and conse-quently several topology models have been proposed. Studies of preseni-lin-interacting proteins have produced further contradiction, primarily regarding the location of the C-terminus.

  • The lively presence of pragmatist doctrines in early 20th-century international debate, their subsequent slow and apparently inexorable decline, and their recent revival are intertwined with the fate of other currents of thought that have marked the revision of traditional philosophical systems. This volume aims to clarify the most recent developments in this process, focusing on the key theoretical issues in the revival of salient themes in the classic tradition of American philosophy within the context of analytical thought.

  • Concerns about the potential environmental, social and economic impacts of climate change have led to a major international debate over what could and should be done to reduce emissions of greenhouse gases, which are claimed to be the main cause. There is still a scientific debate over the likely scale of climate change, and the complex interactions between human activities and climate systems, but, in the words of no less than Governor Arnold Schwarzenegger, ‘I say the debate is over. We know the science, we see the threat, and the time for action is now.’...

  • Brightly colored condoms, arranged in the shape of bicycles, eyeglasses, or flowers: part of an extensive campaign against the AIDS risk, these have been a common sight on billboards in Germany for several years now. An advertising spot presented on the Arte television channel (which defines itself as the cultural television channel of Europe) calls on viewers to “fight together.” The spots on German television (distributed by both private and public channels) are about “not giving AIDS a chance.

  • First principles molecular dynamics studies on active-site models of flavo-cytochromeb2 (l-lactate : cytochrome coxidoreductase, Fcb2), in complex with the substrate, were carried out for the first time to contribute towards establishing the mechanism of the enzyme-catalyzed l-lactate oxidation reaction, a still-debated issue.

  • The C-peptide of proinsulin is important for the biosynthesis of insulin, but has been considered for a long time to be biologically inert. Recent studies in diabetic patients have stimulated a new debate about its possible regulatory role, suggesting that it is a hormonally active peptide. We des-cribe structural studies of the C-peptide using 2D NMR spectroscopy.

  • The complex C1 triggers the activation of the Complement classical pathway through the recognition and binding of antigen–antibody complex by its subunit C1q. The globular region of C1q is responsible for C1 binding to the immune complex. C1q can also bind nonimmune molecules such as DNAand sulfated polysaccharides, leading either to the activation or inhibition of Complement. The binding site of these nonimmune ligands is debated in the literature, and it has beenproposed to be located either in the globular region or in the collagen-like regionof C1q, or inboth....

  • Forecasts point to a huge increase in energy demand over the next 25 years, with a direct and immediate impact on the exhaustion of fossil fuels, the increase in pollution levels and the global warming that will have significant consequences for all sectors of society. Irrespective of the likelihood of these predictions or what researchers in different scientific disciplines may believe or publicly say about how critical the energy situation may be on a world level, it is without doubt one of the great debates that has stirred up public interest in modern times....

  • Stem cell research has the potential to affect the lives of millions of people in the United States and around the world. This research is now regularly front-page news because of the controversy surrounding the derivation of stem cells from human embryos. Realizing the promise of stem cells for yielding new medical therapies will require us to grapple with more than just scientific uncertainties. The stem cell debate has led scientists and nonscientists alike to contemplate profound issues, such as who we are and what makes us human beings.

  • Astronomy is certainly the oldest science and that of astronomer probably the oldest profession. This second assertion is notoriously debatable, but one can safely assume that in a primitive civilized society the (remunerated) shaman or priest had to be an astronomer to be credible.

  • The urgent need to ensure the conservation of biological diversity is now widely recognised, but the role of an intellectual property rights regime as an instrument for biodiversity conservation is poorly understood and often hotly debated. This volume is a detailed analysis of the economic and scientific rationales for the use of a property rights-based approach to biodiversity conservation. It discusses the justification for, and implemen- tation of, intellectual property rights regimes as incentive systems to encourage conservation.

  • Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition.

  • This book examines general changes in the regulation of the health professions in the United Kingdom from a social scientific perspective. It also considers the historical and contemporary development of regulation for a selection of key occupational groups in this context, with reference to wider debates about the health professions. Interest in new approaches to regulation was prompted by the fact that, by the late 1990s, a number of important shifts were taking place in relation to such groups in this country. These included the following trends.
