Laptops in the Living Room: Mobile Technologies and the Divide between Work and Private Time among Interactive Agency Workers
Authors: Ladner Sam
Published: March 2017

This article examines how mobile technology use affects the division between private and work time among workers in interactive advertising agencies. These workers are frequent users of both personal and company-issued mobile technology. This article investigates the strategies workers use to restrict workplace access during their private time. Relying on the social construction of technology as a point of departure, this article investigates the impact of mobile technologies, as well as the organizational context in which they are used. Using a mixed-method approach, this article demonstrates that the use of mobile technologies does indeed render the home/work division more permeable, but it is not their use alone that determines this effect. Rather, it is the underlying social relations of workplaces that affect how individuals negotiate the use of these technologies in non-work time and space.
Building Wi-Fi Networks for Communities: Three Canadian Cases
Authors: Middleton Catherine
Published: March 2017

This paper explores three Canadian wireless network projects that demonstrate that Wi-Fi technologies, like landline telephones, radio, and hydro, can be used to bring services to local communities. It is our position that despite the strengths and weaknesses of Fredericton’s eZone, Montréal’s Île Sans Fil, and the Lac Seul network in Northern Ontario, these three highlighted Wi-Fi networks demonstrate that a public information utilities model is still a useful lens through which to understand the development and implementation of telecommunications in Canada. Through our case studies, we have observed that in order for municipally based and community Wi-Fi networks to successfully take root in a community, it is advantageous to build on existing technological infrastructure. Moreover, municipal and community needs must be considered in the project. Finally, a cohort of interested advocates from the region is needed.
Virilio: Mimesis, Mourning, and Modern Technology
Authors: McAllister Kirsten Emiko
Published: March 2017

In The Vision Machine (1994) Paul Virilio uses powerful imagery to warn us about the consequences of our increasing dependence on “vision machines.” With little use, he claims that our sense organs will atrophy and we will degenerate into neurologically simple organisms. This article examines his use of imagery, arguing (after Nicholsen, 1997; Saussy, 2006; and Taussig, 1993) that he mimetically replicates cultural anxieties as well as the destructive drives he critiques. Arguing that he mourns the loss of an ideal human animal of knowledge constituted through the Greek practice of techne¯ (Heidegger,1977), the article further questions whether his writing is symptomatic of “left melancholia” (Brown, 2003).
Getting the Picture: Airtime and Lineup Bias on Canadian Networks during the 2006 Federal Election
Authors: Barber Marsha
Published: March 2017

This research article addresses the issue of media bias as it played out on Canada’s three major television networks during coverage of the 2006 federal election. The data suggest that in spite of critics’ concerns that networks exhibit political bias, this was not evident. However, a more subtle and systemic bias was apparent. Front-runners (i.e., parties that polls indicated would do well) received substantially more coverage than other parties. Conversely, parties that were perceived as being less successful received less coverage than political front-runners. In addition, reports about front-runners were placed higher in the lineup. These empirical findings should be of interest to critics on both the right and left of the political spectrum who are concerned about the gatekeeping and agenda-setting functions of the media.
Listening to Labour: Mainstream Media, Talk Radio, and the 2005 B.C. Teachers Strike
Authors: Gunster Shane
Published: March 2017

In October 2005, B.C. public school teachers conducted a two-and-a-half-week illegal strike that attracted widespread support from the public. This article conducts a comparative content and discourse analysis of the news coverage provided by the leading provincial outlets in three media types: The Vancouver Sun (newspaper), the News Hour on Global (television), and The Bill Good Show (political talk radio). The Bill Good Show’s open-ended, participatory format, coupled with the host’s commitment to journalistic norms of objectivity and diversity, allowed teachers to play an active and significant role in shaping discussion and debate about the strike. Conversely, coverage by The Vancouver Sun and the News Hour, both owned by CanWest Global, largely failed to reflect public opinion and instead reproduced the ideological bias of conventional strike scripts.
Live from the Met: Digital Broadcast Cinema, Medium Theory, and Opera for the Masses
Authors: Heyer Paul
Published: March 2017

Beginning with the 2006-07 season, the New York Metropolitan Opera began broadcasting live performances into select movie theatres around the world. This article explores the phenomenon using an approach known as medium theory. It draws from the work of three analysts in that tradition who have focused on the performing and recording arts: Edmund Carpenter, John Ellis, and James Monaco. The author coins the term “digital broadcast cinema” (DBC) to refer to the virtual experience of seeing a live opera on a big screen in high definition. The Met’s project is assessed with respect to the conventions that govern theatre, broadcast television, and cinema, and with reference to how it both enhances and compromises the traditional concert-going experience.
Digital Taylorization of Social Service Work
Authors: Rideout Vanda N.
Published: March 2017

As the Canadian government shifted to a neo-liberal policy regime, social service delivery was “contracted out” to community organizations such as the Riverview Centre. The outsourcing objectives were to keep delivery costs low and to build in efficiencies by relying on new technological systems. This paper shows the problems arising from the Riverview Centre’s inadequate technology system when interfacing with advanced government networks to report on employment services provided to clients. These advanced networks centralized control of social-service labour through digital Taylorization practices. Electronic reporting tasks have been standardized and routinized such that labour processes are shaped by the digital technology systems. The delivery of employment services conceals the dual aspect of the commodification of the social workers’ labour through contract employment and technological means.
Home Improvement Television:Holmes on HomesMakes It Right
Authors: Bruce Jean
Published: March 2017

Holmes on Homes is a Canadian home improvement television program and the centrepiece of HGTV (Home and Garden Television), featuring Mike Holmes as the series’ star contractor and host. This paper argues that by looking back at earlier incarnations of film and television melodrama, we can determine the way in which Holmes on Homes reinvents the home improvement subgenre. By playing out reality TV’s central tension between fiction and non-fiction, Holmes on Homes reveals its larger themes of justice and redemption, which befit its unique position between the documentary and the classic melodrama.
Looking at Shirley, the Ultimate Norm: Colour Balance, Image Technologies, and Cognitive Equity
Authors: Roth Lorna
Published: March 2017

Until recently, due to a light-skin bias embedded in colour film stock emulsions and digital camera design, the rendering of non-Caucasian skin tones was highly deficient and required the development of compensatory practices and technology improvements to redress its shortcomings. Using the emblematic “Shirley” norm reference card as a central metaphor reflecting the changing state of race relations/aesthetics, this essay analytically traces the colour adjustment processes in the industries of visual representation and identifies some prototypical changes in the field. The author contextualizes the history of these changes using three theoretical categories: the ‘technological unconscious’ (Vaccari, 1981), ‘dysconsciousness’ (King, 2001), and an original concept of ‘cognitive equity,’ which is proposed as an intelligent strategy for creating and promoting equity by inscribing a wider dynamic range of skin tones into image technologies, products, and emergent practices in the visual industries.
Out of the Fog and into the Future: Directions of Public Relations, Theory Building, Research, and Practice
Authors: Wehmeier Stefan
Published: March 2017

This Delphi study is about the future directions of public relations. International public-relations experts, scholars and practitioners, are asked about the relationship between theory and practice, as well as the impact of different disciplines, academic concepts, and theories on public relations. By looking at recent developments in public relations, different trends become obvious: The practical field, as well as public relations teaching, is drifting toward a management perspective. “Communication management” is a term that has been adopted heavily in recent years. The academic research, however, although still lacking theory building, tries to tie in to sociological theories. It looks as though public relations, on the one hand, tries to become more accepted in the management field and, on the other hand, claims its place in society. This study underlines both trends.
A Cold Cut Crisis: Listeriosis, Maple Leaf Foods, and the Politics of Apology
Authors: Greenberg Josh , Elliott Charlene
Published: March 2017

In the summer of 2008, one of the worst cases of food contamination in Canadian history was confirmed when the Canadian Food Inspection Agency and Maple Leaf Foods issued a “health hazard alert” warning the public not to serve or consumer Sure Slice brand cold cuts. This localized warning quickly spiralled into a major listeriosis epidemic. More than 200 Maple Leaf Foods products were recalled, but not in time to prevent 20 deaths, the illness of thousands more and a class action lawsuit. This article explores Maple Leaf’s crisis response strategy. Locating our analysis in relation to theorizing about the legitimacy problems that corporations and other powerful actors face in late modernity, it demonstrates that Maple Leaf’s apology was effective in terms of restoring consumer trust and confidence to the extent that it addressed the uncertainties and anxieties that are endemic to contemporary risk society; and, more broadly, it ‘worked’ by disrupting the distribution of risk and blame to other stakeholders.
Lorsque la moralisation ne suffit plus : l’alimentation à l’heure de la lutte au surpoids et des aliments fonctionnels
Authors: Vigneault Karine
Published: March 2017

In the past few years, discourses of war on obesity and functional foods have come to occupy a prominent place amidst the current multiplicity of practices concerned with the “problem” of food and eating. I suggest that, interestingly, both offer a serious challenge to nutritional science’s moralizing approach to food in putting forth a rational rather than moral conception of the subject; a “truth” that, coupled with a relational notion of risk, tends to naturalize a relatively new strategy in the government of food practices: action on environments.
Le « look » numérique des magazines de mode féminins canadiens de langue française
Authors: Bélanger Pierre C , Desjardins Véronique
Published: March 2017

This article examines the move of French-Canadian fashion magazines towards digital platforms. It focuses on a “logic of cohabitation” between the print and web versions. The magazine’s presence on different mobile devices has also been observed. The results of the analysis reveal that contents developed for digital versions of the analyzed magazines fill a utilitarian function and tend to be complementary to the print version. The latter is appreciated for its tactile properties and is perceived as a reference in terms of information. As for the mobile magazine, it acts as a provider of instantly available bite-sized content.
Dangerous Shortcuts: Representations of Sexual Minority Refugees in the Post-9/11 Canadian Press
Authors: Jenicek Ainsley
Published: March 2017

Canadian newspapers are a principal source of information on refugees claiming asylum in Canada on the basis of persecution for their sexual orientation. Many articles rely on culturally racist and classist stereotypes of sexual minorities to demonstrate claimants’ legitimacy. Refugees’ stories are further deployed as “mediating agents” to confirm Canada’s “superiority” over other regions, particularly those identified as Islamic. To determine what thematic constructions are most prevalent among Canadian news sources, the authors conducted a critical discourse analysis (CDA) and secondary textual analysis of articles culled from five Canadian English-language newspapers, employing critical race and queer theories as framing devices.
Urban Mediascapes and Multicultural Flows: Assessing Vancouver’s Communication Infrastructure
Authors: Ahadi Daniel
Published: March 2017

This paper adopts a communication infrastructure model in mapping the flow and meaning of ethnic media in Vancouver and their interaction with local, national, and global conceptions of a public commons. A communication infrastructure consists of a “thick” social network of media and organizations, which create and disseminate everyday conversations and news to any given community. Without the existence of a sustainable communication infrastructure, communities cannot form and function. The intersection of social capacity and media infrastructure, then, becomes an important predictor of potential for democratic deliberation and political engagement. Presenting an empirical study of ethnic media in Vancouver, this article asks how well these outlets provide resources to construct inclusion in an urban setting. A more complex infrastructure was mapped than anticipated, but several blind spots were still found. A set of recommendations is made to expand the politics of inclusion and recognition of shared citizenship and civic engagement.
The Royal Tour of 1939 as a Media Event
Authors: Vipond Mary
Published: March 2017

This article examines three radio broadcasts from the royal tour of 1939, namely those covering the departure of King George VI and Queen Elizabeth from Niagara Falls, Ontario, on their way to visit the United States on June 7, 1939. The analysis contributes to the debate about the function of “media events” sparked by Daniel Dayan and Elihu Katz’s eponymous 1992 book. While Dayan and Katz argue that historic national televised ceremonies enhance community loyalty and integration, their critics suggest that they place too little emphasis on issues of hierarchy and power, especially the power of the media themselves. This study concludes that by their effective use of radio to exploit the symbolism of monarchical ceremony, natural spectacle, and international portals, the Canadian Broadcasting Corporation’s announcers helped to legitimize and augment the authority of the fledgling Canadian public broadcaster.
The “Neoliberal Turn” in Provincial Cultural Policy and Administration in Québec and Ontario: The Emergence of ‘Quasi-Neoliberal’ Approaches
Authors: Gattinger Monica
Published: March 2017

This article examines the influence of neoliberalism on cultural policy in Québec and Ontario. It explores the origins and specificities of government intervention in the cultural sector in each province and then analyzes the extent of the “neoliberal turn” and its impacts on cultural policy since the 1980s. The authors argue that while both provinces have been influenced by neoliberalism, neither has rejected the traditional cultural and social objectives of its policies in favour of solely economic imperatives. Rather, they have progressively grafted economic market-based objectives onto their existing policy frameworks, in what the authors characterize as ‘quasi-neoliberal’ approaches.
Report: Citizen Journalism in Burma and the Legacy of Graham Spry
Authors: Pidduck Julianne
Published: March 2017

This report explores issues arising from the 2009 Graham Spry Memorial events on the subject of citizen journalism in Burma, staging an encounter between aspects of the work of Democratic Voice of Burma (DVB) and Graham Spry’s legacy as a politically-engaged intellectual and lobbyist. I discuss the role of DVB as a “citizen journalism” network embedded in a “space of flows.” Particular emphasis is placed on the organization’s judicious use of “old” and “new” media in the struggle for democracy in Burma. The report also takes up Nancy Fraser’s notion of “scales of justice” to discuss the power of media flows in a transnational public sphere and the limits of citizen journalism within pro-democracy movements in autocratic regimes such as that of Burma. I conclude with a discussion of the stakes of representation and inclusion, notably for questions of gender and ethnic diversity.
On the Policy Reflex in Canadian Communication Studies
Authors: Wagman Ira
Published: March 2017

This commentary notes the existence of a “policy reflex” in Canadian communication studies. The author suggests that many scholars engage in issues having to do with policy even if “policy analysis” is not the goal of scholarship. This tendency is in part due to a limited understanding of policy or a tendency among some scholars to see their work as “critical” over other possible characterizations. In many cases a turn to policy has a symbolic function, marking absence rather than presence. In a research field characterized by major gaps in research and in the face of convoluted or missing data, what we call “policy analysis” often emerges largely by default. The article discusses consequences of this reflex on policy scholarship and public discourses of culture.
Canadian Copyright: History, Change, and Potential
Authors: Bannerman Sara
Published: March 2017

The first part of this article reviews Canada’s international copyright history and the role Canada has played in international copyright from the nineteenth century to the present day. In the part two, the author asks whether we can be optimistic or pessimistic about Canada’s role, and the role of international institutions more generally, in promoting solutions to the social policy and social justice concerns raised by the expansion of intellectual property. The author argues that Canada’s history, while demonstrating Canada’s potential to support progressive change, has not borne out certain middle power ideals.
The Institutional Development of Indigenous Broadband Infrastructure in Canada and the United States: Two Paths to “Digital Self-Determination”
Authors: McMahon Rob
Published: March 2017

For years, indigenous groups in Canada and the United States have argued for public policies to support the coordinated development of community-driven broadband infrastructure. Despite different national contexts and opportunities for policy implementation, case studies from Canada and the United States reflect similarities in the strategic approaches of two indigenous groups to argue for increased “digital self-determination.” However, the opportunities to express these arguments and the specific forms they take are shaped by the institutional contexts in each state. This article illustrates how efforts to articulate a strategy of “digital self-determination” are contingent on national contexts.
McLuhan’s Grammatical Theology
Authors: Peters John Durham
Published: March 2017

This article offers one more assessment of the work of Marshall McLuhan, using his recently published dissertation on the trivium as a window for reading his later, more media-focused works. Seeing McLuhan as a grammatical theologian casts fresh light on several well-known themes in his thought: his encyclopedic method with its surrealist juxtapositions, his insistence on medium specificity, his trouble with mathematics, his love of conceptual incommensurabilities, and, above all, his suppression of dialectic as a mode of thought and argument. In terms of the trivium, McLuhan was a grammarian in his intellectual commitments and a rhetorician in his practical performances, but he was never a dialectician.
Between Life-World and Technical Systems: Dialectics in the Digital Locus
Authors: Josgrilberg Fabio B.
Published: March 2017

Strategic political, technological, and economic choices concerning the future of information and communications technologies are made in constant tension with everyday life practices. Despite the friction that arises from these power relations, how human beings relate existentially to technical objects may be a major factor in future outcomes of the so-called Information Society. What is at stake here is a dialectical tension between the lived world—the Lebenswelt, or the life-world experience—and existing technical systems. Given this context of people’s relationships to technology, this article aims to advance phenomenological perspectives on digital media through a dialogue between Milton Santos’ geographical approach to technical systems and Michel de Certeau’s theories about everyday life.
Covering Copenhagen: Climate Change in BC Media
Authors: Gunster Shane
Published: March 2017

In December 2009, considerable media attention was devoted to climate change as global leaders gathered in Copenhagen for a two-week summit to negotiate an extension to the Kyoto Protocol. This article conducts a discourse and content analysis of how regional media in British Columbia covered the event, with a particular focus on how climate politics was framed. A wide range of sources encompassing different media and different ownership structures was analyzed. Debates about climate science played very little role in media coverage. Conversely, focus on the summit ensured that the political dimensions of climate change played a central role. Climate politics, however, was framed in very different ways by mainstream and alternative media.

Published: March 2017

This article describes how the Canadian printed news media depicted the homeless and their situations between 1987 and 2007. Our study used a descriptive, cross-sectional design and a content analysis was conducted on selected newspaper articles on homelessness issues. The main themes were housing-related issues, profiling of homelessness, health-related issues, economic factors, illegal activities, community aid and support, and social factors as cause of homelessness. Housing related issues, community aid and support, profiling of homelessness and economic factors were addressed in 85.3% of the stories. This study provides a retrospective examination of the media’s interests in and portrayal of the homeless and homelessness issues.
Relationship between mindfulness and positive affect of Chinese older adults: Optimism as mediator
Authors: Zeng Weinan , Gu Meixi
Published: March 2017

We examined the mediating role of optimism in the relationship between mindfulness and positive affect with a sample of 277 Chinese people aged between 51 and 65 years who completed the Mindful Attention Awareness Scale, the Life Orientation Test-Revised, and the Positive Affect subscale
of the Positive and Negative Affect Schedule. Pearson correlation analysis results showed a significant positive relationship between mindfulness, optimism, and positive affect. Mediation analysis results further showed that optimism partially mediated the association between mindfulness and
positive affect. Thus, as the findings indicated that enhancing mindfulness levels results in greater optimism, this should be considered an effective measure for promoting positive affect in older adults.
Communication satisfaction and trust among Turkish adolescent siblings
Authors: Örücü Müge Çelik , Er Sühendan
Published: March 2017

The relationships that exist among brothers and sisters have been much less researched and observed than other kinds of family relationships. Thus, the impact of sibling dyads' gender and age difference on Turkish adolescents' communication satisfaction and trust was examined. The sample
consisted of 272 (154 female, 118 male) Turkish high school students, all of whom were aged between 14 and 18 years and had 1 younger sibling. They were asked to complete the Sibling Communication Satisfaction Scale and the Dyadic Trust Scale. A significant gender difference was obtained for
both trust and communication satisfaction, wherein females were more likely than males were to trust and be satisfied with their level of communication with their siblings, especially in the case of same-gender siblings. However, no significant result was found for age difference in terms
of either trust or communication satisfaction.
Top management team pay, firm size and performance relationship in Saudi Arabian firms
Authors: Altuwaijri Basmah , Kalyanaraman Lakshmi
Published: March 2017

We study the relationship of top management team’s (TMT) pay with firm performance with a sample of 80 firms listed on Saudi stock market. We find that firm performance and firm size emerge as significant variables in explaining TMT compensation. This is in line with many of the earlier studies which proxy the firm performance as the ability of the firm to pay higher compensation and firm size as a proxy for complexity of operations. We find that large firms and firms with better financial performance pay higher compensation to their TMT. When we group the firms into large firms and small firms, we find that firm size and firm performance are significant variables that influence TMT pay only in case of large firms. Our results show that firm size does not influence TMT pay and only firm performance impacts TMT pay.
CEOs´ monetary incentives and performance of Mexican firms
Authors: Watkins-Fassler Karen
Published: March 2017

This paper analyzes if changes in CEO remuneration and the execution of CEO stock options impact firm performance, under an emerging market context. Data is obtained from 88 non-financial companies listed in the Mexican Stock Exchange (2001-2012). A dynamic panel specification is employed, and regressions are run through the Generalized Method of Moments. Some evidence is found on the negative relationship between flat monetary incentives and Mexican firm performance, specifically for normal times. In addition, financial incentives based on results (particularly CEO stock options) do not imply higher firm performance. Results suggest that companies in particular contexts should move towards the development of CEOs, more than promoting mostly monetary incentives for boosting firm performance. Companies operating in Mexico will gain from hiring intrinsically motivated CEOs, together with testing different extrinsic rewards (neither flat nor stock options) in order to attain additive effects on intrinsic motivation.

Introduction/Objective. Pneumothorax is one of the most common complications of cardiac rhythm management (CRM) devices implantation. We aimed to assess the incidence of pneumothorax after implantation of these devices and to determine risk factors for this complication. Methods. A retrospective, observational study included patients in whom CRM devices were implanted, pacing system was upgraded, or lead revision was performed during 2012 at the Pacemaker Center, Clinical Center of Serbia. We determined the connection between different variables, including sex, age, type of implanted device, prior history of chronic obstructive pulmonary disease, operator experience, venous access, the use of intravenous contrast during procedure, and the development of pneumothorax as the procedure-related complication, using multiple logistic regression. Results. A total of 999 patients were included in this study. The patients? mean age was 68.1 ?} 9.2 years; 665 (66.6%) patients were male. The incidence of pneumothorax was 1.8% and an invasive treatment of this complication was required in 13 (72.2%) patients. Pneumothorax was more frequent in women (B = -2.136, p = 0.015), in patients with age > 75 years (B = 4.315, p = 0.001), venous access with subclavian vein puncture (B = 2.672, p = 0.045), and use of intravenous contrast during procedure (B = 3.155, p = 0.007). Conclusion. Pneumothorax is a relatively rare complication of CRM device implantation, and for reducing its incidence, cephalic vein cut-down should be preferred to subclavian or axillary vein puncture as venous access, axillary vein puncture should not be avoided when cephalic vein cannot be found or used, and in the case of difficult vein puncture, contrast venography should be done immediately, before risky punctures.
Histological evaluation of tissue reactions to newly synthetized calcium silicate- and hydroxyapatite-based bioactive materials: in vivo study
Authors: Opacic-Galic Vanja , Petrovic Violeta , Jokanovic Vukoman , Zivkovic Slavoljub
Published: March 2017

Introduction/Objective. Development of materials which could be used as biological bone substitutes is one of the most valuable and active fields of biomaterial research. The goal of the study was to research the reaction of tissue on calcium silicate- (CS) and hydroxyapatitebased (CS-HA) newly synthesized nanomaterials, after being implanted into the subcutaneous tissue of a rats and direct pulp capping of rabbit teeth. Methods. The tested materials were implanted in 40 Wistar male rats, sacrificed after seven, 15, 30, and 60 days. The direct pulp capping was performed on the teeth of rabbits. Cavities were prepared on the vestibular surface of the incisors. The animals were sacrificed after 10 and 15 days. The control material was mineral trioxide aggregate (MTA). Histological analysis covered the tracking of inflammatory reaction cellular components, presence of gigantic cells, and necrosis of the tissue. Results. Seven days after the implantation, the strongest inflammatory response was given by the MTA (3.3 ?} 0.48), while CS and CS-HA scored 3 ? 0.71. After 60 days, the rate of inflammatory reactions dropped, which was the least visible with CS-HA (0.2 ? 0.45). The least visible inflammatory reaction of the rabbits? pulp tissue was spotted with the CS (1.83 ? 0.75), than with the MTA and CS-HA (2.67 ? 1.53, 3 ? 0.63). Conclusion. The newly synthesized materials caused a slight reaction of the subcutaneous tissue. CS-HA showed the best tissue tolerance. Nanostructural biomaterials caused a slight to moderate inflammatory reaction of the rabbits? pulp tissue only in the immediate vicinity of the implanted material.
Transapical transcatheter aortic valve implantation in a patient with small body weight complicated by severe hypotension: An enigma successfully solved by echocardiography
Authors: Lazarevic Aleksandar , Naganuma Toru , Mitomo Satoru , Kawamoto Hiroyoshi , Nakao Tatsuya , Ishiguro Hisaaki , Nakamura Sunao
Published: March 2017

Introduction. Transcatheter aortic valve implantation is currently considered an alternative treatment for older patients with severe aortic valve stenosis and increased surgical risk, but can be associated with multiple life-threatening complications. Case outline. An 83-year-old woman with severe symptomatic aortic stenosis, body weight of 29 kg and body surface area of 1.1 m2 underwent transcatheter aortic valve implantation via transapical access. Severe hypotension occurred before the valve implantation, due to temporary distortion of the mitral valve apparatus by stiff wire, leading to acute mitral regurgitation. This complication was immediately recognized by continuous transesophageal echocardiography and managed by simple wire retrieval instead of applying mechanical circulatory support. After rewiring and predilatation of the stenotic aortic valve, a 23 mm balloon-expandable transcatheter stent-prosthetic valve was successfully implanted. Conclusion. This case demonstrates that continuous imaging during transcatheter aortic valve implantation is key to rapid diagnosis of life-threatening complications, associated with the procedure, especially during the early learning curve in transapical approach.
GLUT4 Is Not Necessary for Overload-Induced Glucose Uptake or Hypertrophic Growth in Mouse Skeletal Muscle
Authors: McMillin Shawna L. , Schmidt Denise L. , Kahn Barbara B. , Witczak Carol A.
Published: March 2017

GLUT4 is necessary for acute insulin- and contraction-induced skeletal muscle glucose uptake, but its role in chronic muscle loading (overload)-induced glucose uptake is unknown. Our goal was to determine whether GLUT4 is required for overload-induced glucose uptake. Overload was induced in mouse plantaris muscle by unilateral synergist ablation. After 5 days, muscle weights and ex vivo [3H]-2-deoxy-d-glucose uptake were assessed. Overload-induced muscle glucose uptake and hypertrophic growth were not impaired in muscle-specific GLUT4 knockout mice, demonstrating that GLUT4 is not necessary for these processes. To assess which transporters mediate overload-induced glucose uptake, chemical inhibitors were used. The facilitative GLUT inhibitor cytochalasin B, but not the sodium-dependent glucose cotransport inhibitor phloridzin, prevented overload-induced uptake demonstrating that GLUTs mediate this effect. To assess which GLUT, hexose competition experiments were performed. Overload-induced [3H]-2-deoxy-d-glucose uptake was not inhibited by d-fructose, demonstrating that the fructose-transporting GLUT2, GLUT5, GLUT8, and GLUT12 do not mediate this effect. To assess additional GLUTs, immunoblots were performed. Overload increased GLUT1, GLUT3, GLUT6, and GLUT10 protein levels twofold to fivefold. Collectively, these results demonstrate that GLUT4 is not necessary for overload-induced muscle glucose uptake or hypertrophic growth and suggest that GLUT1, GLUT3, GLUT6, and/or GLUT10 mediate overload-induced glucose uptake.
Facteurs environnementaux associés au trouble du spectre de l’autisme : étude de délimitation portant sur les années 2003 à 2013
Authors: Ng Michelle , de Montigny Joanne , Ofner Marianna , Do Minh
Published: March 2017

Introduction

Le nombre d’enfants chez lesquels on diagnostique un trouble du spectre de l’autisme (TSA) grimpe rapidement depuis une décennie. L’étiologie de ce trouble est toutefois en grande partie inconnue, même si la contribution de l’environnement est importante par rapport à celle de la génétique. Nous avons procédé à une étude de délimitation pour évaluer en détail l’état actuel des connaissances sur les facteurs environnementaux présents depuis le stade de la préconception jusqu’au début de la vie que l’on associe au TSA et pour dégager les lacunes de la recherche.

Méthodologie

Nous avons cherché dans les bases de données électroniques MEDLINE, PsycINFO et ERIC des articles portant sur des facteurs de risque potentiels ou des facteurs de protection des environnements physiques et sociaux associés au TSA et à ses sous-catégories entre le 1er janvier 2003 et le 12 juillet 2013. Nous avons regroupé les articles en thèmes généraux en fonction de l’exposition environnementale : facteurs chimiques, physiologiques, nutritionnels et sociaux.

Résultats

Nous avons trouvé plus de 50 000 publications, mais après élimination des études inadmissibles il est resté 315 articles. La plupart de ces études portaient sur les facteurs psychologiques, suivis de près par les facteurs chimiques et, à un degré beaucoup moindre, les facteurs nutritionnels et sociaux associés au TSA. En dépit d’une masse importante de publications et de nombreuses études hétérogènes, quelques facteurs de risque se sont démarqués régulièrement : facteurs chimiques comme les polluants atmosphériques causés par la circulation; facteurs physiologiques, dont l’âge avancé des parents, les naissances prématurées, l’insuffisance de poids à la naissance, l’hyperbilirubinémie et les grappes de complications de la grossesse et enfin le statut de la mère vis-à-vis de l’immigration. En dépit de recherches poussées sur les vaccins, les faits révèlent de façon écrasante que rien n’appuie l’existence d’un lien avec le TSA.

Conclusion

Le manque d’uniformité, de temporalité et de spécificité des liens entre les facteurs environnementaux et le TSA demeure l’obstacle le plus important dans l’établissement de liens de cause à effet. Une recherche plus robuste s’impose pour supprimer le manque d’uniformité dans les publications. Les recherches futures devraient porter sur des mécanismes sous-jacents des liens entre facteurs de risque que nous avons identifiés et le TSA.
