    Island endemics are typically differentiated from their mainland progenitors in behavior, morphology, and genetics, often resulting from long-term evolutionary change. To examine mechanisms for the origins of island endemism, we present a phylogeographic analysis of whole mitochondrial genomes from the endangered island fox (Urocyon littoralis), endemic to California's Channel Islands, and mainland gray foxes (U. cinereoargenteus). Previous genetic studies suggested that foxes first appeared on the islands >16,000 years ago, before human arrival (~13,000 cal BP), while archaeological and paleontological data supported a colonization >7000 cal BP. Our results are consistent with initial fox colonization of the northern islands probably by rafting or human introduction ~9200-7100 years ago, followed quickly by human translocation of foxes from the northern to southern Channel Islands. Mitogenomes indicate that island foxes are monophyletic and most closely related to gray foxes from northern California that likely experienced a Holocene climate-induced range shift. Our data document rapid morphological evolution of island foxes (in ~2000 years or less). Despite evidence for bottlenecks, island foxes have generated and maintained multiple mitochondrial haplotypes. This study highlights the intertwined evolutionary history of island foxes and humans, and illustrates a new approach for investigating the evolutionary histories of other island endemics.

    The media affects individuals' behaviors, especially by means of news and advertisements. In this study, we evaluated health content of organ donation and transplantation news in the printed media and on television programs for a 1-year period in Turkey. We examined 2449 news items in 230 newspapers and magazines; 1179 news programs on 45 television channels, all concerning organ donation and transplantation. The news obtained from the Media Pursuit Center were transferred to an electronic file to evaluate the format and content of the news. Nine variables were examined about the scope and the formal characteristics of the news: the publication name, its type, the province, the date, the headline, the title length, the presence of a photograph, or its kind, the news size, and the page number. In the content analysis of the news, we also examined 9 variables: the topic, the message of the headline, the property of the words in the title, the identification of photographs in the news, the age, gender of actors in the news, as well as donor or recipient. In a summary, print media and television channels, failed to show sufficient information about organ donation and transplantation. The percentage of news about organ donation and transplantation was small and mostly negative items in the media. On television channels, sufficient place was not given to organ donation and transplantation. The news in printed media and on television channels was not about motivated or altruistic behavior. The pattern of organ donation and transplantation news is important in terms of perception and comment by the public. Furthermore it directly affects the perception of the news by the reader.

  7. They Came, They Liked, They Commented: Social Influence on Facebook News Channels.

    Winter, Stephan; Brückner, Caroline; Krämer, Nicole C

    2015-08-01

    Due to the increasing importance of social networking sites as sources of information, news media organizations have set up Facebook channels in which they publish news stories or links to articles. This research investigated how journalistic texts are perceived in this new context and how reactions of other users change the influence of the main articles. In an online experiment (N=197), a Facebook posting of a reputable news site and the corresponding article were shown. The type of user comments and the number of likes were systematically varied. Negative comments diminished the persuasive influence of the article, while there were no strengthening effects of positive comments. When readers perceived the topic as personally relevant, comments including relevant arguments were more influential than comments with subjective opinions, which can be explained by higher levels of elaboration. However, against expectations of bandwagon perceptions, a high number of likes did not lead to conformity effects, which suggests that exemplifying comments are more influential than statistical user representations. Results are discussed with regard to effects of news media content and the mechanisms of social influence in Web 2.0.

  11. Attitudinal impact and cognitive channelling of immigration stereotypes through the news

    JJ Igartua

    2013-10-01

    Full Text Available Introduction: Based on research on the framing effect and research on the treatment of immigration, the processes of reception and impact of news about crime are analyzed. Method: We conducted two experimental investigations in which participants were exposed to a news story and later filled in a questionnaire with self-report scales. Two independent variables were manipulated: the mention of protagonists’ national/ geographic origin in the news story and the involvement with the topic. Results: The study indicates that when the involvement with the news story is low, the presence of information about the nationality of the protagonist exerted an indirect effect through attitudinal impact. However, when involvement is high, the indirect effect is explained by the activation of trains of thought which influence the formation and/or reinforcement of negative beliefs about immigration. Conclusions: The results are consistent with a dual model of news framing effects and reinforce the recommendations made by some organisations about not reporting the nationality of the protagonists of a criminal act in news programmes.

  14. Diet patterns of island foxes on San Nicolas Island relative to feral cat removal

    Cypher, Brian L.; Kelly, Erica C.; Ferrara, Francesca J.; Drost, Charles A.; Westall, Tory L.; Hudgens, Brian

    2017-01-01

    Island foxes (Urocyon littoralis) are a species of conservation concern that occur on six of the Channel Islands off the coast of southern California. We analysed island fox diet on San Nicolas Island during 2006–12 to assess the influence of the removal of feral cats (Felis catus) on the food use by foxes. Our objective was to determine whether fox diet patterns shifted in response to the cat removal conducted during 2009–10, thus indicating that cats were competing with foxes for food items. We also examined the influence of annual precipitation patterns and fox abundance on fox diet. On the basis of an analysis of 1975 fox scats, use of vertebrate prey – deer mice (Peromyscus maniculatus), birds, and lizards – increased significantly during and after the complete removal of cats (n = 66) from the island. Deer mouse abundance increased markedly during and after cat removal and use of mice by foxes was significantly related to mouse abundance. The increase in mice and shift in item use by the foxes was consistent with a reduction in exploitative competition associated with the cat removal. However, fox abundance declined markedly coincident with the removal of cats and deer mouse abundance was negatively related to fox numbers. Also, annual precipitation increased markedly during and after cat removal and deer mouse abundance closely tracked precipitation. Thus, our results indicate that other confounding factors, particularly precipitation, may have had a greater influence on fox diet patterns.

  17. Effects of roads on survival of San Clemente Island foxes

    Snow, N.P.; Andelt, William F.; Stanley, T.R.; Resnik, J.R.; Munson, L.

    2012-01-01

    Roads generate a variety of influences on wildlife populations; however, little is known about the effects of roads on endemic wildlife on islands. Specifically, road-kills of island foxes (Urocyon littoralis) on San Clemente Island (SCI), Channel Islands, California, USA are a concern for resource managers. To determine the effects of roads on island foxes, we radiocollared foxes using a 3-tiered sampling design to represent the entire population in the study area, a sub-population near roads, and a sub-population away from roads on SCI. We examined annual survival rates using nest-survival models, causes of mortalities, and movements for each sample. We found the population had high annual survival (0.90), although survival declined with use of road habitat, particularly for intermediate-aged foxes. Foxes living near roads suffered lower annual survival (0.76), resulting from high frequencies of road-kills (7 of 11 mortalities). Foxes living away from roads had the highest annual survival (0.97). Road-kill was the most prominent cause of mortality detected on SCI, which we estimated as killing 3-8% of the population in the study area annually. Based on movements, we were unable to detect any responses by foxes that minimized their risks from roads. The probabilities of road-kills increased with use of the road habitat, volume of traffic, and decreasing road sinuosity. We recommend that managers should attempt to reduce road-kills by deterring or excluding foxes from entering roads, and attempting to modify behaviors of motorists to be vigilant for foxes. ?? 2011 The Wildlife Society.

A very short overview of these activities is given in this issue of the ATLAS News Letter, while the various topics will be described in more detail in the next issues. The Physics and Combined Performance groups are working in four main areas: 1) Assess the ATLAS potential for physics, with emphasis on new channels and ideas. Recent examples are Extra-dimensions, invisible Higgs decays, heavy ion physics, the expected potential of a "Super-LHC" running at a luminosity of 10^35, etc.. 2) Improve the understanding of the detector performance and optimise the reconstruction algorithms. Examples of issues in the pipeline are: can we tag charm-jet ? What can we gain in the jet energy resolution by combining the calorimeter and tracker information to reconstruct the jet energy ? 3) Follow detector changes and detector-related issues and monitor the impact on the perform...

  20. Theoretical study on the mechanism of the reaction of FOX-7 with OH and NO2 radicals: bimolecular reactions with low barrier during the decomposition of FOX-7

    Zhang, Ji-Dong; Zhang, Li-Li

    2017-12-01

    The decomposition of 1,1-diamino-2,2-dinitroethene (FOX-7) attracts great interests, while the studies on bimolecular reactions during the decomposition of FOX-7 are scarce. This study for the first time investigated the bimolecular reactions of OH and NO2 radicals, which are pyrolysis products of ammonium perchlorate (an efficient oxidant usually used in solid propellant), with FOX-7 by computational chemistry methods. The molecular geometries and energies were calculated using the (U)B3LYP/6-31++G(d,p) method. The rate constants of the reactions were calculated by canonical variational transition state theory. We found three mechanisms (H-abstraction, OH addition to C and N atom) for the reaction of OH + FOX-7 and two mechanisms (O abstraction and H abstraction) for the reaction of NO2 + FOX-7. OH radical can abstract H atom or add to C atom of FOX-7 with barriers near to zero, which means OH radical can effectively degrade FOX-7. The O abstraction channel of the reaction of NO2 + FOX-7 results in the formation of NO3 radical, which has never been detected experimentally during the decomposition of FOX-7.

  9. Multi-population comparison of resource exploitation by island foxes: Implications for conservation

    B.L. Cypher

    2014-12-01

    Full Text Available Imperiled island foxes are inherently resource-limited by their insular ecology. We examined food use on all 6 islands where they occur to assess resource exploitation patterns. Over 40 different food items were identified with item use varying among islands. Sixteen items occurred with ≥10% frequency in annual fox diets: deer mice, birds, lizards, beetles, beetle larvae, Jerusalem crickets, silk-spinning sand crickets, grasshoppers, earwigs, snails, and fruits of toyon, manzanita, prickly pear cactus, ice plant, Australian saltbush, and summer holly. Foxes used a diversity of food items with variations among islands attributable to island-specific availabilities. Deer mice in particular appeared to be preferred. Foxes also exhibited extensive use of non-native items, such as ice plant fruits, European snails, and earwigs, and foxes may even be dependent on these items on some islands. To increase food security and promote population stability, we recommend (1 continuing and enhancing habitat restoration efforts on all islands, (2 increasing the abundance of native items in association with any removals of non-native species used by foxes, and (3 monitoring annual trends in abundance of key food items as well as periodic monitoring of item use by foxes to determine functional responses to changes in item availability.

Looking for the connections between public opinion and the media, focusing on the position of the American government during the first Gulf War, as Mueller, Seaver and Page stated, shows that the United States government has been trying to influence the media in critical situations like wartime. In this study, we are attempting to evaluate Embedded Journalism as a new method of coverage in the Iraq 2003 War. There are plenty of studies in the field of embedded journalism; however, this study is going to measure the objectivity of the Foxnews’ coverage, according to Mindich theory (2000.

    News from Journal House Guidelines for Submission The Journal's current Guide to Submissions can be found on pages 29-30 of this issue. They have been streamlined a bit and also include a handy check list. This information is also available on JCE Online at http://jchemed.chem.wisc.edu/Journal/Authors/. Wanted: Demo Checkers The Tested Demonstrations column needs people who like to try out demos. Column editor Ed Vitz is looking for additional volunteers to serve as "checkers" for manuscripts that have been submitted to the Journal for possible publication as Tested Demonstrations. A checker is expected to perform two functions: to review the manuscript for accuracy and novelty, and to attempt to perform the demonstration according to the procedure supplied by the author. Checkers may suggest important improvements in demonstration procedures, and for their efforts they are cited in the byline when the manuscript is published. For instance, the demo showing the yellow cascading precipitates (lead iodide) made from potassium iodide and lead nitrate was submitted by Wobbe de Vos and checked by Kim Kostka. The (yellow) cascading precipitates are from "Using Large Glass Cylinders To Demonstrate Chemical Reactions" that appeared in the April 1999 issue of JCE. We prefer that checkers begin the review process (which may in some cases involve procuring supplies) very soon after being contacted so that their review can be completed in the timely manner that authors deserve. Checkers are usually teachers who routinely present lecture demonstrations in their classes in either high school or colleges. We try not to call on checkers more often than once a year, which is one of the reasons for this request. Another is that we lose many highly valued, experienced checkers to retirement or other endeavors. Prospective checkers may want to look at a copy of the JCE Tested Demonstration Evaluation Form.

    Unilateral laparoscopic ovariectomy was attempted in a red fox (Vulpes vulpes) with an ovarian cyst through single portal access. The ovarian cyst was resistant to conservative therapy using gonadotropin-releasing hormone. A 10-mm laparoscope with an operating channel was introduced into the abdomen via a 12-mm umbilical portal. The left ovary and cyst (34.1 x 30.8 mm) were fixed to the left abdominal wall by a transabdominal suspension suture. The ovarian pedicles and ligaments were progressively cauterized and transected with a multifunction bipolar electrocoagulation forceps. The resected cystic ovary was exteriorized through the umbilical portal site. The surgical time was 42 min, and no intra- and postoperative complications were encountered. Two months after the surgery mating was observed, and the fox gave birth to three healthy cubs 56 days after the mating. This is the first report of using laparoscopy in the red fox with an ovarian cyst.

    News from Journal House Perspective on JCE Online Recently a reader asked us for a perspective on JCE Onlinehow the chemical education community is receiving it and how the Journal staff itself views it. We share our responses below. Subscriber Numbers How many people subscribe to JCE Online+? As of June 1, 1999, our records show that 13% of individual JCE subscriptions in the USA include JCE Online+. This percentage has increased significantly during the past year- in June 1998 it was approximately 4% and December 1998 about 7%. Almost all subscribers to JCE Online subscribe to print as well. Since JCE Online has only very recently been made available to institutional subscribers, there are no numbers to report. There has been considerable interest in online from libraries. Given that JCE Online+ is a fairly recent subscriber option and that many subscribers have a wait-and-see approach to any new option, we feel that the numbers above are quite high. The steady growth is encouraging. Online Usage How many people visit our Web site? Statistics for the period January 1, 1999, through May 31, 1999, that may be of interest include: Total Pages Served 361,115 Total Visits 138,377 Total Unique Visitors 51,744 Total Repeat Visitors 11,536 Average Visit Length 03:05 Average Requests/Visit 10.8 Average Pages/Visit 2.6 Average Daily Visits 916 Online Rationale and Expectations JCE Online is a very important part of the whole Journal, but we do not expect it to supplant print: online and print are very different media. Usage of JCE Online is growing steadily; our subscribers are realizing what we have learned: it is not possible to deliver the Journal in the print medium alone- print is no longer adequate to accomplish our mission. Examples of things not possible in print include: ·JCE Index to all 76 years of Journal issues, available all the time with responses within seconds. ·Supplementary materials that are important to only a limited number of our subscribers

    The small intestines of 420 wild canids (111 corsac foxes, 191 red foxes and 118 wolves) from Mongolia, were examined for adult worms of the genus Echinococcus. The Mongolian genotype of Echinococcus multilocularis was found in fifteen red foxes and four wolves, whereas two genotypes (G6/7 and G10) of Echinococcus canadensis were found in two and three wolves, respectively. No adult Echinococcus worms were found in the corsac foxes examined. The genotypes of E. multilocularis and E. canadensis are discussed in terms of host specificity and distribution in Mongolia. The importance of wolves in the completion of the life cycle of Echinococcus spp. is also discussed.

Twitter...... is different from email in that retweeting does not depend on pre-existing social relations, but often occur among strangers, thus in this respect Twitter may be more similar to traditional news media.

  7. BRAZILIAN NEWS PORTALS CHARACTERISTICS

    Heloiza G. Herckovitz

    2011-02-01

    Full Text Available A content analysis of four Brazilian news media portals found that economic news dominated the top headlines with little attention paid to education, the environment and welfare. Other trends included a focus on local events and national news sources, reliance on few sources, mostly official ones, and a low percentage of news that fitted the concept of newsworthiness (a combination of both social significance and deviance concepts. Other findings of a study of 432 top news stories published by UOL, Estadão, iG and Terra during a 15-day period between February and March 2008 indicate that the top portions of the portals’ front pages carry news that lacks story depth, editorial branding, and multimedia applications. The results suggest that online news portals are in their infancy although Brazil has the largest online population of Latin America. This study hopes to shed light on the gatekeeping process in Brazilian news portals. Brazilian media portals have yet to become a significant editorial force able to provide knowledge about social issues and public affairs in a socially responsible fashione.

    Higman, S A; McKay, F J; Engstrom, P F; O'Grady, M A; Young, R C

    2000-01-01

    Fox Chase Cancer Center developed a format for affiliation with community providers in 1986. Fox Chase Network was formed to establish hospital-based community cancer centers to increase access to patients involved in clinical research. Under this program, the Fox Chase Network now contributes 500 patients per year to prevention and clinical research studies. As relationships with community providers form, patient referrals have increased at Fox Chase Cancer Center and for each Fox Chase Network member. A dedicated staff is required to operate the central office on a day-to-day basis as well as at each affiliate. We have found this to be a critical element in each program's success. New challenges in the cancer business-increasing volumes with declining revenue-have caused us to reconfigure the services offered to affiliates, while maintaining true to our mission: to reduce the burden of human cancer.

  10. Behavioral interactions of penned red and arctic foxes

    Rudzinski, D.R.; Graves, H.B.; Sargeant, A.B.; Storm, G.L.

    1982-01-01

    Expansion of the geographical distribution of red foxes (Vulpes vulpes) into the far north tundra region may lead to competition between arctic (Alopex lagopus) and red foxes for space and resources. Behavioral interactions between red and arctic foxes were evaluated during 9 trials conducted in a 4.05-ha enclosure near Woodworth, North Dakota. Each trial consisted of introducing a male-female pair of arctic foxes into the enclosure and allowing them to acclimate for approximately a week before releasing a female red fox into the enclosure, followed by her mate a few days later. In 8 of 9 trials, red foxes were dominant over arctic foxes during encounters. Activity of the arctic foxes decreased upon addition of red foxes. Arctic foxes tried unsuccessfully to defend preferred den, resting, and feeding areas. Even though the outcome of competition between red and arctic foxes in the Arctic is uncertain, the more aggressive red fox can dominate arctic foxes in direct competition for den sites and other limited resources.

  11. Mitochondrial Analysis of the Most Basal Canid Reveals Deep Divergence between Eastern and Western North American Gray Foxes (Urocyon spp.) and Ancient Roots in Pleistocene California.

    Goddard, Natalie S; Statham, Mark J; Sacks, Benjamin N

    2015-01-01

    Pleistocene aridification in central North America caused many temperate forest-associated vertebrates to split into eastern and western lineages. Such divisions can be cryptic when Holocene expansions have closed the gaps between once-disjunct ranges or when local morphological variation obscures deeper regional divergences. We investigated such cryptic divergence in the gray fox (Urocyon cinereoargenteus), the most basal extant canid in the world. We also investigated the phylogeography of this species and its diminutive relative, the island fox (U. littoralis), in California. The California Floristic Province was a significant source of Pleistocene diversification for a wide range of taxa and, we hypothesized, for the gray fox as well. Alternatively, gray foxes in California potentially reflected a recent Holocene expansion from further south. We sequenced mitochondrial DNA from 169 gray foxes from the southeastern and southwestern United States and 11 island foxes from three of the Channel Islands. We estimated a 1.3% sequence divergence in the cytochrome b gene between eastern and western foxes and used coalescent simulations to date the divergence to approximately 500,000 years before present (YBP), which is comparable to that between recognized sister species within the Canidae. Gray fox samples collected from throughout California exhibited high haplotype diversity, phylogeographic structure, and genetic signatures of a late-Holocene population decline. Bayesian skyline analysis also indicated an earlier population increase dating to the early Wisconsin glaciation (~70,000 YBP) and a root height extending back to the previous interglacial (~100,000 YBP). Together these findings support California's role as a long-term Pleistocene refugium for western Urocyon. Lastly, based both on our results and re-interpretation of those of another study, we conclude that island foxes of the Channel Islands trace their origins to at least 3 distinct female founders from

  13. Tweeting News Articles

    Marco Toledo Bastos

    2013-09-01

    Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

    2017-01-01

    The Rocky Mountain Red Fox (Vulpes vulpes macroura), once common in the Blue Mountains ecoregion of northeastern Oregon, was considered rare in eastern Oregon by the 1930s and thought to be extirpated by the 1960s, when putatively new Red Fox populations began to appear. Although the new foxes were long presumed to be nonnative (originating from...

    Hartley, Jannie Møller

    The aim of the paper is to make explicit how the different categories are applied in the online newsroom and thus how new categories can be seen as positioning strategies in the form of radicalisations of already existing categories. Thus field theory provides us with tools to analyse how online...... journalists are using the categorisations to create hierarchies within the journalistic field in order to position themselves as specialists in what Tuchman has called developing news, aiming and striving for what today is know as breaking news and the “exclusive scoop,” as the trademark of online journalism...... in a media environment where immediacy rules (Domingo 2008a).

  5. Effect of British hunting ban on fox numbers.

    Baker, Philip J; Harris, Stephen; Webbon, Charlotte C

    2002-09-05

    Pressure to ban the hunting of foxes with hounds in Britain has fuelled debate about its contribution to the control of fox populations. We took advantage of a nationwide one-year ban on fox-hunting during the outbreak of foot-and-mouth disease (FMD) in 2001 to examine this issue and found that the ban had no measurable impact on fox numbers in randomly selected areas. Our results argue against suggestions that fox populations would increase markedly in the event of a permanent ban on hunting.

  8. Comparison of selected immunological parameters in silver and polar foxes

    Kostro, K.; Woloszyn, S.

    1996-01-01

    The aim of the work was to compare selected nonspecific immunological parameters in silver and polar foxes. It was found that out of three mitogens (Con A, La and PWM) only Con A stimulated the strongest lymphocyte proliferation in both species of foxes. Mean stimulation indices and the absolute values of incorporated thymidine were significantly higher in polar foxes. The average percentages of phagocytes and the fatal indices of neutrophils were comparable in both species of foxes, while the mean value of the phagocyte index was much higher in the silver fox. However, in polar foxes a higher concentration of lysozyme in the blood serum was found. The differences in the parameters may influence the susceptibility of these foxes to some infections already at the level of nonspecific primary response. (author)

    2017-12-01

    Full Text Available The last presidential elections in the United States of America (2016 have brought to the international public opinion’ s attention the phenomenon of “fake news”. Though it isn’t a new phenomenon, the spread of fake information for manipulating and misinforming the masses has existed in all historical periods. This time the phenomenon was noticed because of the number of fake news and, especially because of their impact, starting the discussion whether the victory of Donald Trump happened because of fake news and raising the question whether this phenomenon is a danger to democracy. An important reaction came also from the part of technology companies, of tech giants, Google and Facebook especially, which want the implementation of the phenomenon. Misinformation with public speech under the form of fake news brings to discussion the responsibility in the online space, but also the protection of people against this phenomenon.

Thirty pieces of news about internal affairs of Iran together with their Persian translations were downloaded from the corresponding website, i.e. 30 pieces of English news and their corresponding Persian translations from the Euro News website and 30 pieces of English news with their corresponding translations from the BBC website. The frequency of lexical items was observed to not differ significantly. Two sets of translations were compared to their source texts based on four discursive strategies of hyperbole, polarization, vagueness and euphemism. An independent-samples t-test was conducted to compare the frequency of strategies applied by the two news agencies. Results revealed no significant difference between the two agencies except for the discursive strategy of vagueness.

    A post mortem examination on a young fox which had been observed to be clinically ill revealed a severe infection with Angiostrongylus vasorum. A further 11 foxes were examined and four were infected with the parasite; three of these also had advanced lesions of sarcoptic mange. The cases all occurred outside the previously defined focus of endemic infection for dogs in Cornwall and they appear to be the first recorded cases of A vasorum in foxes in the United Kingdom.

  7. There is no news like bad news: women are more remembering and stress reactive after reading real negative news than men.

    Marie-France Marin

    Full Text Available With the advent of specialized television channels offering 24-hour coverage, Internet and smart phones, the possibility to be constantly in contact with the media has increased dramatically in the last decades. Despite this higher access to knowledge, the impact media exposure has on healthy individuals remains poorly studied. Given that most information conveyed in the media is negative and that upon perception of threat, the brain activates the stress system, which leads to cortisol secretion, we decided to determine how healthy individuals react to media information. Accordingly, we investigated whether reading real negative news (1 is physiologically stressful, (2 modulates one's propensity to be stress reactive to a subsequent stressor and (3 modulates remembrance for these news. Sixty participants (30 women, 30 men were randomly assigned to either twenty-four real neutral news excerpts or to twenty-four real negative excerpts for 10 minutes. They were then all exposed to a well-validated psychosocial stressor, the Trier Social Stress Test (TSST, which consists of an anticipation phase of 10 minutes and a test phase of 10 minutes. A total of eight salivary cortisol samples were collected, at 10-minutes intervals, throughout the experimental procedure. One day later, a free recall of the news was performed. Results showed that although reading negative news did not lead to change in cortisol levels (p>0.05, it led to a significant increase in cortisol to a subsequent stressor in women only (p<0.001. Also, women in the negative news condition experienced better memory for these news excerpts compared to men (p<0.01. These results suggest a potential mechanism by which media exposure could increase stress reactivity and memory for negative news in women.

  11. Sensing the News: User Experiences when Reading Locative News

    2012-02-01

    Full Text Available This article focuses on user experiences on reading location-aware news on the mobile platform and aims to explore what experiences this kind of locative journalism generates and how such experiences change the users’ social interaction with news. We produced a specially designed mobile application and tailored news stories specific to this project called LocaNews in order to explore participants’ relation to the content in this journalistic format. The result is generated through a field study and a questionnaire of 32 people to find out how they experience the news presented in this format. The user participants’ responses are analyzed based on their news experiences, contextualizing places and their social interaction with the news within this form of journalism. Results showed that the local, semi-local and non-local user approaches the locative news in a different manner, but that the average user found this kind of news more interesting and more informative than ordinary news. The participants also have a problem identifying this as journalism, rather than an information service.

  12. Missense polymorphisms in the MC1R gene of the dog, red fox, arctic fox and Chinese raccoon dog.

    Nowacka-Woszuk, J; Salamon, S; Gorna, A; Switonski, M

    2013-04-01

    Coat colour variation is determined by many genes, one of which is the melanocortin receptor type 1 (MC1R) gene. In this study, we examined the whole coding sequence of this gene in four species belonging to the Canidae family (dog, red fox, arctic fox and Chinese raccoon dog). Although the comparative analysis of the obtained nucleotide sequences revealed a high conservation, which varied between 97.9 and 99.1%, we altogether identified 22 SNPs (10 in dogs, six in farmed red foxes, two in wild red foxes, three in arctic foxes and one in Chinese raccoon dog). Among them, seven appeared to be novel: one silent in the dog, three missense and one silent in the red fox, one in the 3'-flanking region in the arctic fox and one silent in the Chinese raccoon dog. In dogs and red foxes, the SNPs segregated as 10 and four haplotypes, respectively. Taking into consideration the published reports and results of this study, the highest number of missense polymorphisms was until now found in the dog (9) and red fox (7). © 2012 Blackwell Verlag GmbH.

    Rando, Halie M; Stutchman, Jeremy T; Bastounes, Estelle R; Johnson, Jennifer L; Driscoll, Carlos A; Barr, Christina S; Trut, Lyudmila N; Sacks, Benjamin N; Kukekova, Anna V

    2017-09-01

    The de novo assembly of the red fox (Vulpes vulpes) genome has facilitated the development of genomic tools for the species. Efforts to identify the population history of red foxes in North America have previously been limited by a lack of information about the red fox Y-chromosome sequence. However, a megabase of red fox Y-chromosome sequence was recently identified over 2 scaffolds in the reference genome. Here, these scaffolds were scanned for repeated motifs, revealing 194 likely microsatellites. Twenty-three of these loci were selected for primer development and, after testing, produced a panel of 11 novel markers that were analyzed alongside 2 markers previously developed for the red fox from dog Y-chromosome sequence. The markers were genotyped in 76 male red foxes from 4 populations: 7 foxes from Newfoundland (eastern Canada), 12 from Maryland (eastern United States), and 9 from the island of Great Britain, as well as 48 foxes of known North American origin maintained on an experimental farm in Novosibirsk, Russia. The full marker panel revealed 22 haplotypes among these red foxes, whereas the 2 previously known markers alone would have identified only 10 haplotypes. The haplotypes from the 4 populations clustered primarily by continent, but unidirectional gene flow from Great Britain and farm populations may influence haplotype diversity in the Maryland population. The development of new markers has increased the resolution at which red fox Y-chromosome diversity can be analyzed and provides insight into the contribution of males to red fox population diversity and patterns of phylogeography. © The American Genetic Association 2017.

  14. Contact: Releasing the news

    Pinotti, Roberto

    The problem of mass behavior after man's future contacts with other intelligences in the universe is not only a challenge for social scientists and political leaders all over the world, but also a cultural time bomb as well. In fact, since the impact of CETI (Contact with Extraterrestrial Intelligence) on human civilization, with its different cultures, might cause a serious socio-anthropological shock, a common and predetermined worldwide strategy is necessary in releasing the news after the contact, in order to keep possible manifestations of fear, panic and hysteria under control. An analysis of past studies in this field and of parallel historical situations as analogs suggests a definite "authority crisis" in the public as a direct consequence of an unexpected release of the news, involving a devastating "chain reaction" process (from both the psychological and sociological viewpoints) of anomie and maybe the collapse of today's society. The only way to prevent all this is to prepare the world's public opinion concerning contact before releasing the news, and to develop a long-term strategy through the combined efforts of scientists, political leaders, intelligence agencies and the mass media, in order to create the cultural conditions in which a confrontation with ETI won't affect mankind in a traumatic way. Definite roles and tasks in this multi-level model are suggested.

  15. Hillslope failure and paraglacial reworking of sediments in response to glacier retreat, Fox Valley, New Zealand.

    McColl, Samuel T.; Fuller, Ian C.; Anderson, Brian; Tate, Rosie

    2017-04-01

    Climate and glacier fluctuations influence sediment supply to glacier forelands, which in turn influences down-valley hazards to infrastructure and tourism within glacier forelands. At Fox Glacier, one of New Zealand's most iconic and popular glaciers, rapid retreat has initiated a range of hillslope and valley floor responses, that present a cascade of hazards and changes that need to be carefully managed. Fox Glacier has retreated many kilometres historically, with 2.6 km of retreat since the mid-20th century, and a phase of rapid retreat of 50-340 m per year since 2009. To study the system response to past and ongoing glacial retreat at the Fox valley, morphological changes are being observed using time-lapse photography and the annual collection of high-resolution digital elevation models (DEMs) and orthophoto mosaics. The DEMs are being produced using Structure from Motion photogrammetry from UAV/RPAS and helicopter platforms, and are being used, along with manual ground surveying, to produce ground surface change models (DoDs; DEMs of Difference) and sediment budgets for the valley. Results from time-lapse photography and DoDs show that glacial retreat has initiated destabilisation and (mostly chronic) mass movement of surficial glacial sediments on the valley slopes near the glacier terminus. Alluvial fans farther down valley are actively growing, reworking glacial and landslide sediments from tributary catchments. These paraglacial sediments being delivered to the proglacial river from the glacier terminus and alluvial fans are driving aggradation of the valley floor of decimetres to metres per year and maintaining a highly dynamic braid plain. Valley floor changes also include the melting of buried dead ice, which are causing localised subsidence at the carpark and one of the alluvial fans. The unstable slopes and active debris fans, aggrading and highly active river channel, ground subsidence, add to the spectacle but also the hazards of the Fox valley

  17. Shaggy Lame Fox Syndrome in Pribilof Island Arctic Foxes ( Alopex lagopus pribilofensis), Alaska.

    Spraker, T R; White, P A

    2017-03-01

    A previously unrecognized condition is described in wild free-ranging Pribilof arctic foxes ( Alopex lagopus pribilofensis) from the Pribilof Islands, Alaska, USA. This condition is called shaggy lame fox syndrome (SLFS) denoting the primary clinical signs first observed. Criteria used to suspect SLFS on gross examination included emaciation, failure to shed winter pelage and moderate to severe polyarthritis. Criteria used to confirm SLFS histologically included polyarthritis (characterized by lymphoplasmacytic synovitis, tenosynovitis, bursitis, periosteal bony proliferation, and periarticular lymphoplasmacytic vasculitis) and systemic leukocytoclastic vasculitis. Other histological lesions often found included renal cortical infarcts, myocarditis with myocardial infarcts, lymphoplasmacytic meningitis, lymphoplasmacytic cuffing of meningeal and a few cerebral vessels, and cavitating infarcts of the brainstem and thalamus. The cause of SLFS is not known at this time; however, the gross and histological lesions suggest that the cause of SLFS may be a bacterial polyarthritis with a secondary immune-mediated vasculitis. These lesions are consistent with changes described with Erysipelothrix rhusiopathiae in domestic dogs; E. rhusiopathiae was identified from the synovial membrane of a swollen stifle joint and the kidney from one fox using real-time polymerase chain reaction and with culture from a fox that had gross and histological lesions of SLFS. Therefore, E. rhusiopathiae is a possible etiological agent for SLFS.

  19. A spring aerial census of red foxes in North Dakota

    Sargeant, A.B.; Pfeifer, W.K.; Allen, S.H.

    1975-01-01

    Systematic aerial searches were flown on transects to locate adult red foxes (Vulpes vulpes), pups, and rearing dens on 559.4 km2 (six townships) in eastern North Dakota during mid-May and mid-June each year from 1969 through 1973 and during mid-April 1969 and early May 1970. The combined sightings of foxes and fox dens from the mid-May and mid-June searches were used to identify individual fox families. The number of fox families was used as the measurement of density. Dens, highly visible during the mid-May searches, were the most reliable family indicator; 84 percent of 270 families identified during the study were represented by dens. Adult foxes second in importance, were most observable during the mid-May searches when 20 to 35 percent of those estimated to be available were sighted. Adult sightings during other search periods ranged from 4 to 17 percent of those available. Pup sightings were the most variable family indicator, but they led to the discovery of some dens. Sources of error for which adjustment factors were determined are: den moves exceeding criterion established for the spacing of dens in a single family, overestimation of the number of fox families living near township boundaries, and the percentage of fox families overlooked during the aerial searches. These adjustment factors appeared to be largely compensatory.

    1995-01-01

    The red fox, Vulpes vulpes, was investigated with snow tracking, radiotracking and directive observation at the Haibei Research Station of Alpine Meadow Ecosystem, Academia Sinica, from March to September 1994. The objectives of this study were to determine the distribution and use of natal dens, activity rhythms, and home range sizes for the foxes.

    In 2011, a group A rotavirus was isolated from the brain of a fox with encephalitis and neurologic signs, detected by rabies surveillance in Italy. Intracerebral inoculation of fox brain homogenates into mice was fatal. Genome sequencing revealed a heterologous rotavirus of avian origin, which could provide a model for investigating rotavirus neurovirulence.

    Rates at which Eastern fox squirrels (Sciurus niger) are exploited in areas open to public hunting may be useful guides for designing fall hunting seasons that are biologically defensible. However, there is a question whether the harvest of fox squirrels by public hunting will even occasionally be great enough to challenge the limit allowed by the best designed...

  3. Dispersal patterns of red foxes relative to population density

    Allen, Stephen H.; Sargeant, Alan B.

    1993-01-01

    Factors affecting red fox (Vulpes vulpes) dispersal patterns are poorly understood but warranted investigation because of the role of dispersal in rebuilding depleted populations and transmission of diseases. We examined dispersal patterns of red foxes in North Dakota based on recoveries of 363 of 854 foxes tagged as pups and relative to fox density. Foxes were recovered up to 8.6 years after tagging; 79% were trapped or shot. Straight-line distances between tagging and recovery locations ranged from 0 to 302 km. Mean recovery distances increased with age and were greater for males than females, but longest individual recovery distances were by females. Dispersal distances were not related to population density for males (P = 0.36) or females (P = 0.96). The proportion of males recovered that dispersed was inversely related to population density (r = -0.94; n = 5; P = 0.02), but not the proportion of females (r = -0.49; n = 5; P = 0.40). Dispersal directions were not uniform for either males (P = 0.003) or females (P = 0.006); littermates tended to disperse in similar directions (P = 0.09). A 4-lane interstate highway altered dispersal directions (P = 0.001). Dispersal is a strong innate behavior of red foxes (especially males) that results in many individuals of both sexes traveling far from natal areas. Because dispersal distance was unaffected by fox density, populations can be rebuilt and diseases transmitted long distances regardless of fox abundance.

  5. Rough-legged buzzards, Arctic foxes and red foxes in a tundra ecosystem without rodents.

    Ivan Pokrovsky

    Full Text Available Small rodents with multi-annual population cycles strongly influence the dynamics of food webs, and in particular predator-prey interactions, across most of the tundra biome. Rodents are however absent from some arctic islands, and studies on performance of arctic predators under such circumstances may be very instructive since rodent cycles have been predicted to collapse in a warming Arctic. Here we document for the first time how three normally rodent-dependent predator species-rough-legged buzzard, arctic fox and red fox - perform in a low-arctic ecosystem with no rodents. During six years (in 2006-2008 and 2011-2013 we studied diet and breeding performance of these predators in the rodent-free Kolguev Island in Arctic Russia. The rough-legged buzzards, previously known to be a small rodent specialist, have only during the last two decades become established on Kolguev Island. The buzzards successfully breed on the island at stable low density, but with high productivity based on goslings and willow ptarmigan as their main prey - altogether representing a novel ecological situation for this species. Breeding density of arctic fox varied from year to year, but with stable productivity based on mainly geese as prey. The density dynamic of the arctic fox appeared to be correlated with the date of spring arrival of the geese. Red foxes breed regularly on the island but in very low numbers that appear to have been unchanged over a long period - a situation that resemble what has been recently documented from Arctic America. Our study suggests that the three predators found breeding on Kolguev Island possess capacities for shifting to changing circumstances in low-arctic ecosystem as long as other small - medium sized terrestrial herbivores are present in good numbers.

  6. Porencephaly in a fennec fox (Vulpes zerda).

    Yamazaki, Mutsumi; Yoshimoto, Saeko; Ishikawa, Tomoko; Une, Yumi

    2016-12-01

    A postmortem examination revealed a large brain cavity in the right cerebral hemisphere of a 9-year-old male fennec (Vulpes zerda). The cavity was filled with cerebrospinal fluid and extended to the right lateral ventricle. Swelling and displacement of the right hippocampal area were also observed. Histologic examination revealed no evidence of previous infarct lesions, hemorrhage, inflammation or invasive tumor cells. Observation of the defective part suggested a local circulatory disorder during the fetal stage, although the cause was not detected. No neurological symptoms that could enable a provisional diagnosis were observed during the course of his life. This is the first report of asymptomatic porencephaly in a fennec fox.

  7. "Reversed" intraguild predation: red fox cubs killed by pine marten.

    Brzeziński, Marcin; Rodak, Lukasz; Zalewski, Andrzej

    2014-01-01

    Camera traps deployed at a badger Meles meles set in mixed pine forest in north-eastern Poland recorded interspecific killing of red fox Vulpes vulpes cubs by pine marten Martes martes . The vixen and her cubs settled in the set at the beginning of May 2013, and it was abandoned by the badgers shortly afterwards. Five fox cubs were recorded playing in front of the den each night. Ten days after the first recording of the foxes, a pine marten was filmed at the set; it arrived in the morning, made a reconnaissance and returned at night when the vixen was away from the set. The pine marten entered the den several times and killed at least two fox cubs. It was active at the set for about 2 h. This observation proves that red foxes are not completely safe from predation by smaller carnivores, even those considered to be subordinate species in interspecific competition.

  11. The good news about giving bad news to patients.

    Farber, Neil J; Urban, Susan Y; Collier, Virginia U; Weiner, Joan; Polite, Ronald G; Davis, Elizabeth B; Boyer, E Gil

    2002-12-01

    There are few data available on how physicians inform patients about bad news. We surveyed internists about how they convey this information. We surveyed internists about their activities in giving bad news to patients. One set of questions was about activities for the emotional support of the patient (11 items), and the other was about activities for creating a supportive environment for delivering bad news (9 items). The impact of demographic factors on the performance of emotionally supportive items, environmentally supportive items, and on the number of minutes reportedly spent delivering news was analyzed by analysis of variance and multiple regression analysis. More than half of the internists reported that they always or frequently performed 10 of the 11 emotionally supportive items and 6 of the 9 environmentally supportive items while giving bad news to patients. The average time reportedly spent in giving bad news was 27 minutes. Although training in giving bad news had a significant impact on the number of emotionally supportive items reported (P woman, unmarried, and having a history of major illness were also associated with reporting a greater number of emotionally supportive activities. Internists report that they inform patients of bad news appropriately. Some deficiencies exist, specifically in discussing prognosis and referral of patients to support groups. Physician educational efforts should include discussion of prognosis with patients as well as the availability of support groups.

  18. Evaluation of stochastic differential equation approximation of ion channel gating models.

    Bruce, Ian C

    2009-04-01

    Fox and Lu derived an algorithm based on stochastic differential equations for approximating the kinetics of ion channel gating that is simpler and faster than "exact" algorithms for simulating Markov process models of channel gating. However, the approximation may not be sufficiently accurate to predict statistics of action potential generation in some cases. The objective of this study was to develop a framework for analyzing the inaccuracies and determining their origin. Simulations of a patch of membrane with voltage-gated sodium and potassium channels were performed using an exact algorithm for the kinetics of channel gating and the approximate algorithm of Fox & Lu. The Fox & Lu algorithm assumes that channel gating particle dynamics have a stochastic term that is uncorrelated, zero-mean Gaussian noise, whereas the results of this study demonstrate that in many cases the stochastic term in the Fox & Lu algorithm should be correlated and non-Gaussian noise with a non-zero mean. The results indicate that: (i) the source of the inaccuracy is that the Fox & Lu algorithm does not adequately describe the combined behavior of the multiple activation particles in each sodium and potassium channel, and (ii) the accuracy does not improve with increasing numbers of channels.

  4. Predation on seabirds by red foxes at Shaiak Island, Alaska

    Petersen, M.R.

    1982-01-01

    Two Red Foxes (Vulpes fulva) that invaded Shaiak Island before the 1976 nesting season had a marked impact on the nesting success of five of seven species of seabirds breeding on the island that year. Common Eiders (Somateria mollissima), Glaucous-winged Gulls (Larus glaucescens), and Common Murres (Uria aalge), that nest in areas accessible to foxes, did not raise any young to fledging. Double-crested Cormorants (Phalacrocorax auritus) were only slightly more successful; 13 (4.3%) of 300 pairs raised one or more young to fledging. Evidence suggested that 21 (35.6%) of 62 pairs of Tufted Puffins (Lunda cirrhata) lost eggs or chicks to foxes, and foxes killed at least 13 (8.3%) of 156 adult puffins on ten sample plots. Conversely, Black-Legged Kittiwakes (Rissa tridactyla) and Pelagic Cormorants (Phalacrocorax pelagicus), which nested primarily on cliffs inaccessible to foxes, lost very few nests. There was no apparent change in general nest site selections by seabirds the following year, when foxes were no longer present. Any avoidance by birds of areas vulnerable to fox predation would probably be discernible only after several years of continuous predation.

  5. Eucoleus boehmi infection in red fox (Vulpes vulpes) from Italy.

    2014-12-15

    In the last decade an increase of the number of red foxes in anthropized habitats across European countries, including Italy, has been observed. This pones implications in terms of disease transmission between wildlife and domestic animals; in fact, there are evidences of the role of foxes as reservoirs and amplifiers of a broad spectrum of parasites infecting pets. The present study evaluated the prevalence of Eucoleus boehmi, an emerging extra-intestinal nematodes of the Capillariinae subfamily, in red foxes. The nasal passages and sinuses of 179 red foxes culled from several areas of northern and central Italy were inspected and the mucosal surfaces were scrapped and examined for adult nematodes and eggs, microscopically and genetically identified. Overall 55 foxes (30.7%) were found to be infected with E. boehmi, i.e. 27 on inspection of the nasal passages and sinuses and 28 on mucosal flush and scraping. The occurrence of E. boehmi was significantly (p fox body condition (mean: 7.8 specimens). These results show that E. boehmi is highly prevalent in the red fox populations of certain areas of Italy. Epidemiological implications are discussed, with a special focus on the role that this wild canid may have in the increasing transmission of nasal eucoleosis to domestic dogs.

    2017-11-01

    Amyloid A (AA) amyloidosis occurs spontaneously in many mammals and birds, but the prevalence varies considerably among different species, and even among subgroups of the same species. The Blue fox and the Gray fox seem to be resistant to the development of AA amyloidosis, while Island foxes have a high prevalence of the disease. Herein, we report on the identification of AA amyloidosis in the Red fox (Vulpes vulpes). Edman degradation and tandem MS analysis of proteolyzed amyloid protein revealed that the amyloid partly was composed of full-length SAA. Its amino acid sequence was determined and found to consist of 111 amino acid residues. Based on inter-species sequence comparisons we found four residue exchanges (Ser31, Lys63, Leu71, Lys72) between the Red and Blue fox SAAs. Lys63 seems unique to the Red fox SAA. We found no obvious explanation to how these exchanges might correlate with the reported differences in SAA amyloidogenicity. Furthermore, in contrast to fibrils from many other mammalian species, the isolated amyloid fibrils from Red fox did not seed AA amyloidosis in a mouse model. © 2017 The Protein Society.

  7. Examination of D. immitis presence in foxes in Serbia

    2014-01-01

    Full Text Available Dirofilariosis is a parasitic disease that usually affects dogs, but it can occur in other carnivore species. Since the disease appears endemically in dogs in some parts of Serbia, the aim of our investigation was to determine whether dirofilariosis exists in wild animals. The study included a total of 150 red foxes (Vulpes vulpes, 30 hunted foxes per region of South Banat, Raska, Rasina, Morava and Zlatibor were examined. After the corpses of foxes were autopsied, the heart and blood vessels were examined macroscopically for the evidence of adult forms of D. immitis. The presence of the agent was found in four foxes from the territory of three municipalities of South Banat: Kovin, Alibunar and Opovo, representing 13.33% of the total number of examined foxes in this region. None of the 120 autopsied foxes from four districts of central Serbia was found to have dirofilaria. The results obtained in investigation lead to conclusion that dirofilariosis exists as a parasitic disease in red foxes in South Banat.

  8. Assessing News Contagion in Finance

    2018-02-01

    Full Text Available The analysis of news in the financial context has gained a prominent interest in the last years. This is because of the possible predictive power of such content especially in terms of associated sentiment/mood. In this paper, we focus on a specific aspect of financial news analysis: how the covered topics modify according to space and time dimensions. To this purpose, we employ a modified version of topic model LDA, the so-called Structural Topic Model (STM, that takes into account covariates as well. Our aim is to study the possible evolution of topics extracted from two well known news archive—Reuters and Bloomberg—and to investigate a causal effect in the diffusion of the news by means of a Granger causality test. Our results show that both the temporal dynamics and the spatial differentiation matter in the news contagion.

    Habermann, R.T.; Herman, C.M.; Williams, F.P.

    1958-01-01

    1) Twenty-one raccoons and 3 red foxes were collected from areas where suspected rabies occurred. All were found to be nonrabid. 2) Distemper was diagnosed in 14 of the 21 raccoons by demonstrating intracytoplasmic and intranuclear inclusions in the brain and visceral tissues. Two of the 3 foxes were considered to have distemper; the clinical signs were typical and mouse inoculation tests were negative for rabies. 3) Deaths of the other 7 raccoons were attributed to: leishmaniasis 1, gastritis 1, bronchopneumonia 1, parasitism 2, car injury 1; 1 showed no significant lesions. The death of 1 fox was attributed to parasitism. 4) Distemper may be a frequent cause of death in raccoons and foxes, in epizootics which simulate rabies.

    Forchhammer, M C; Asferg, T

    2000-01-01

    The influence of parasites on host life histories and populations is pronounced. Among several diseases affecting animal populations throughout the world, sarcoptic mange has influenced many carnivore populations dramatically and during the latest epizootic in Fennoscandia reduced the abundance of red fox by over 70%. While the numerical responses of red fox populations, their prey and their competitors as well as clinical implications are well known, knowledge of how sarcoptic mange affects ...

  7. Gray fox (Urocyon cinereoargenteus parasite diversity in central Mexico

    Norma Hernández-Camacho

    2016-08-01

    Full Text Available Mexico has a long history of parasitological studies in communities of vertebrates. However, the mega diversity of the country makes fauna inventories an ongoing priority. Presently, there is little published on the parasite fauna of gray foxes (Urocyon cinereoargenteus Schereber, 1775 and this study provides new records of parasites for gray foxes in central Mexico. It is a continuation of a series of previous parasitological studies conducted with this carnivore in Mexico from 2003 to the present. A total of 24 foxes in the Parque Nacional El Cimatario (PANEC were trapped, anaesthetized, and parasites recovered. The species found were Dirofilaria immitis, Ctenocephalides canis, C. felis, Euhoplopsillus glacialis affinis (first report for gray foxes in Mexico Pulex simulants, and Ixodes sp. Three additional gray fox carcasses were necropsied and the parasites collected were adult nematodes Physaloptera praeputialis and Toxocara canis. The intensive study of the gray fox population selected for the 2013–2015 recent period allowed for a two-fold increase in the number of parasite species recorded for this carnivore since 2003 (nine to 18 parasite species, mainly recording parasitic arthropods, Dirofilaria immitis filariae and adult nematodes. The parasite species recorded are generalists that can survive in anthropic environments; which is characteristic of the present ecological scenario in central Mexico. The close proximity of the PANEC to the city of Santiago de Queretaro suggests possible parasite transmission between the foxes and domestic and feral dogs. Furthermore, packs of feral dogs in the PANEC might have altered habitat use by foxes, with possible impacts on transmission.

  8. "I Have Good News and Bad News:" The Effects of Power Imbalances and Physical Distance on News-givers' Use of Blended News Delivery

    Legg, Angela M.

    2013-01-01

    People dislike giving bad news, and one strategy they use to ease the process is to pair bad news with some good news, a phenomenon called blended news delivery. Often, blended news arrives from people in power positions such as physicians, managers, or teachers. But followers also find themselves needing to give bad news to those in higher power positions. Similarly, people can choose how they deliver bad news, such as in person or over email. The current study brings much needed empirical a...

  9. Trichinella britovi in a red fox (Vulpes vulpes) from Portugal.

    Lopes, Ana Patrícia; Vila-Viçosa, Maria João; Coutinho, Teresa; Cardoso, Luís; Gottstein, Bruno; Müller, Norbert; Cortes, Helder C E

    2015-06-15

    Trichinellosis is one of the most important foodborne parasitic zoonoses, caused by nematodes of the genus Trichinella. Pigs and other domestic and wild animals, including red foxes (Vulpes vulpes), are sources of Trichinella infection for human beings. Trichinella britovi is the major agent of infection in sylvatic animals and the most important species circulating in the European wildlife. The present study aimed at assessing Trichinella spp. infection in red foxes from the North of Portugal. Forty-seven carcasses of wild red foxes shot during the official hunting season or killed in road accidents were obtained between November 2008 and March 2010. In order to identify the presence of Trichinella spp. larvae in red foxes, an individual artificial digestion was performed using approximately 30 g of muscle samples. Larvae of Trichinella spp. were detected in one (2.1%) out of the 47 assessed foxes. After a multiplex polymerase chain reaction analysis, T. britovi was molecularly identified as the infecting species. The recognition of T. britovi in a red fox confirms that a sylvatic cycle is present in the North of Portugal and that the local prevalence of Trichinella infection in wildlife must not be ignored due to its underlying zoonotic risks.

  10. Cs-137 in Arctic foxes (Alopex lagopus) on Svalbard

    Gwynn, Justin P.; Fuglei, Eva; Dowdall, Mark

    2007-01-01

    This study presents 137 Cs muscle activity concentrations in Arctic foxes (Alopex lagopus) from Svalbard over a period of several years and discusses the transfer of 137 Cs to Arctic foxes through likely predator-prey relationships. Mean 137 Cs activity concentrations and 137 Cs T ag values (per trapping season) ranged from 0.51 ± 2.76 to 1.32 ± 2.89 Bq/kg (w.w.) and 5.1 x 10 -4 to 1.3 x 10 -3 m 2 /kg, respectively. Mean concentration ratios of 137 Cs in Arctic foxes compared to probable prey ranged from 1.0 to 7.9. On Svalbard, transfer of 137 Cs to Arctic foxes is likely to occur via both marine and terrestrial food chains. The relative contribution of marine and terrestrial food sources to the diet of Arctic foxes may vary by location and by season and may lead to either an increase or decrease in the trophic transfer of 137 Cs to Arctic foxes compared to transfer resulting from terrestrial only diets

  11. Accelerated FoxP2 evolution in echolocating bats.

    Gang Li

    Full Text Available FOXP2 is a transcription factor implicated in the development and neural control of orofacial coordination, particularly with respect to vocalisation. Observations that orthologues show almost no variation across vertebrates yet differ by two amino acids between humans and chimpanzees have led to speculation that recent evolutionary changes might relate to the emergence of language. Echolocating bats face especially challenging sensorimotor demands, using vocal signals for orientation and often for prey capture. To determine whether mutations in the FoxP2 gene could be associated with echolocation, we sequenced FoxP2 from echolocating and non-echolocating bats as well as a range of other mammal species. We found that contrary to previous reports, FoxP2 is not highly conserved across all nonhuman mammals but is extremely diverse in echolocating bats. We detected divergent selection (a change in selective pressure at FoxP2 between bats with contrasting sonar systems, suggesting the intriguing possibility of a role for FoxP2 in the evolution and development of echolocation. We speculate that observed accelerated evolution of FoxP2 in bats supports a previously proposed function in sensorimotor coordination.

  12. The forkhead transcription factor FoxY regulates Nanos.

    Song, Jia L; Wessel, Gary M

    2012-10-01

    FoxY is a member of the forkhead transcription factor family that appeared enriched in the presumptive germ line of sea urchins (Ransick et al. Dev Biol 2002;246:132). Here, we test the hypothesis that FoxY is involved in germ line determination in this animal. We found two splice forms of FoxY that share the same DNA-binding domain, but vary in the carboxy-terminal trans-activation/repression domain. Both forms of the FoxY protein are present in the egg and in the early embryo, and their mRNAs accumulate to their highest levels in the small micromeres and adjacent non-skeletogenic mesoderm. Knockdown of FoxY resulted in a dramatic decrease in Nanos mRNA and protein levels as well as a loss of coelomic pouches in 2-week-old larvae. Our results indicate that FoxY positively regulates Nanos at the transcriptional level and is essential for reproductive potential in this organism. Copyright © 2012 Wiley Periodicals, Inc.

    Nedjat, Sima; Nedjat, Saharnaz; Majdzadeh, Reza; Farshadi, Mojgan

    2014-01-01

    People are increasingly interested in health news. As a mass media, the 'Islamic Republic of Iran Broadcasting' (IRIB) has the highest number of target audiences. In Iran, some people follow health news via health programs on satellites and other means of communication. However, all of these programs do not live up to the standards of scientific evidence. In this study, we examined Tehran people's trust in health news disseminated by the IRIB and other mass media outlets. A cross-sectional study was conducted in Tehran. Through multistage sampling, 510 households proportional to size were randomly selected from five regions of Tehran including northern, eastern, western, southern and central regions. One person from each household completed the questionnaire through interviews. The questionnaire included questions on people's level of trust in health news delivered by the IRIB, satellite programs, the internet and magazines. It also included demographic questions. The validity and reliability of the questionnaire was evaluated. Among the interviewees, 50.6% was female. The highest level of trust by the participants was observed in the IRIB (65.2%), and the lowest trust was observed in satellite news (43.4%); pnews broadcasters had more mastery over the subject than the ones in satellite channels (pnews (pnews had improved in the past 10 years. Fifty nine point eight percent of participants believed the quality and accuracy of the IRIB health news was monitored. People's higher level of trust in domestic news as compared to foreign sources and the better status of domestic sources in other areas such as precision in reporting, coverage of more important news, its delivery in lay language, the news broadcasters' proficiency, and other cases - from the participants' point of view - can highlight the significance of designing interventions for changing health behavior among domestic health news producers. Therefore, the results of this study can prove useful to health

  14. Creative Cycling of News Professionals

    Astrid Gynnild, PhD.

    2007-03-01

    Full Text Available The theory of creative cycling emerged from my PhD study of news professionals in Norway. The study was carried out according to classic grounded theory principles (Glaser and Strauss 1967, Glaser 1978, 1998, 2001, 2005, and the area of interest was the performance of news journalism in the multimedia age. The theory runs counter to widespread tendencies of industrial age thinking in news media. It emphasizes news professionals’ search for meaning in their daily work, and suggests that their main concern is self-fulfillment through original contribution. The dilemma and resolution, creative cycling, is a basic social process continuously going within inner and outer framings. It consists of three interrelated dimensions: productive processing, breaks and shifts and inspirational looping.

  15. RHYTHM STRUCTURE IN NEWS READING

    Lluís Mas Manchón

    2013-06-01

    Full Text Available Rhythm is central to news reading in radio and television programs. This paper proposes a three level structure for rhythm in news discourse. It gives a comprehensive definition of rhythm and types of rhythm. Firstly, the Base Rhythm Structure consists of semantic and pragmatic rhythmic accents, coincident with very specific words. Secondly, these accents are grouped together according to type, frequency and order, thereby configuring three types of “rhythmic units” (the Internal Rhythm Structure: starting, main and end units. A last structure level presents four discursive factors that are very important in integrating the overall time structure of news announcing (the Melodic Rhythm Structure. This integral structure for news announcing rhythm should be further tested in acoustic-experimental studies under the criterion of information transmission efficacy.

  16. Are flying-foxes coming to town? Urbanisation of the spectacled flying-fox (Pteropus conspicillatus in Australia.

    Jessica Tait

    Full Text Available Urbanisation of wildlife populations is a process with significant conservation and management implications. While urban areas can provide habitat for wildlife, some urbanised species eventually come into conflict with humans. Understanding the process and drivers of wildlife urbanisation is fundamental to developing effective management responses to this phenomenon. In Australia, flying-foxes (Pteropodidae are a common feature of urban environments, sometimes roosting in groups of tens of thousands of individuals. Flying-foxes appear to be becoming increasingly urbanised and are coming into increased contact and conflict with humans. Flying-fox management is now a highly contentious issue. In this study we used monitoring data collected over a 15 year period (1998-2012 to examine the spatial and temporal patterns of association of spectacled flying-fox (Pteropus conspicillatus roost sites (camps with urban areas. We asked whether spectacled flying-foxes are becoming more urbanised and test the hypothesis that such changes are associated with anthropogenic changes to landscape structure. Our results indicate that spectacled flying-foxes were more likely to roost near humans than might be expected by chance, that over the period of the study the proportion of the flying-foxes in urban-associated camps increased, as did the number of urban camps. Increased urbanisation of spectacled flying-foxes was not related to changes in landscape structure or to the encroachment of urban areas on camps. Overall, camps tended to be found in areas that were more fragmented, closer to human habitation and with more urban land cover than the surrounding landscape. This suggests that urbanisation is a behavioural response rather than driven by habitat loss.

  17. Politics and Politicians – Main Topic and Main Characters on Television News

    Viktorija Car

    2010-01-01

    Full Text Available The paper examines the relationship between television as a medium, and politics and politicians as the content of television news in Croatia. The first part of the paper explains the models of ‘media logic’, ‘partisan logic’ and ‘party logic’. The second part of the paper presents the results of the research conducted on the representative sample of primetime news HTV Dnevnik for the period 1991-2009, and Nova TV Dnevnik and RTL Vijesti for the period 2005-2009. The goal of the research was to examine the presence of political topics on primetime news, as well to what extent politicians are presented as main characters. The results show a sustained decline of politics on the news and their simultaneous replacement by news on disasters and lifestyle. Further, citizens and their opinion become more important than opinions of politicians, experts and scientists. Comparing the news on public service television and on commercial televisions, the author elaborates on the internal processes and changes of the television medium and finally introduces the concept of ‘power logic’ to explain news selection and news editing on the Croatian TV channels.

  6. Red fox predation on breeding ducks in midcontinent North America

    Sargeant, Alan B.; Allen, Stephen H.; Eberhardt, Robert T.

    1984-01-01

    Red fox (Vulpes vulpes) predation on nesting ducks was assessed by examining 1,857 adult duck remains found at 1,432 fox rearing dens from 1968 to 1973. Dabbling ducks were much more vulnerable to foxes than diving ducks. Dabbling ducks (1,798) found at dens consisted of 27% blue-winged teals (Anas discors), 23% mallards (A. platyrhynchos), 20% northern pintails (A. acuta), 9% northern shovelers (Spatula clypeata), 8% gadwalls (A. strepera), 3% green-winged teals (A. crecca), 2% American wigeons (A. americana), and 10% unidentified. Relative abundance of individual species and nesting chronology were the most important factors affecting composition of ducks taken by foxes. Seventy-six percent of 1,376 adult dabbling ducks and 40% of 30 adult diving ducks for which sex was determined were hens. In western North Dakota and western South Dakota, 65% of mallard and northern pintail remains found at dens were hens compared with 76% in eastern North Dakota and eastern South Dakota (P fox predation rates on ducks. Predation rate indices ranged from 0.01 duck/den in Iowa to 1.80 ducks/den in eastern North Dakota. Average annual predation rate indices for dabbling ducks in a 3-county intensive study area in eastern North Dakota were closely correlated with May pond numbers (r = 0.874, P foxes than hens of late nesting species. Predation rate indices were expanded to estimate total numbers of ducks taken by fox families during the denning season. Estimated numbers of dabbling ducks taken annually by individual fox families in 2 physiographic regions comprising the intensive study area ranged from 16.1 to 65.9. Predation was highest during wet years and lowest during dry years and averaged lower, but was more variable, in the region where tillage was greatest and wetland water levels were least stable. Predation in the intensive study area averaged 2.97 adult dabbling ducks/ km2/year and represented an estimated average annual loss of 13.5% of hen and 4.5% of drake

  7. Crystallization and preliminary crystallographic studies of FoxE from Rhodobacter ferrooxidans SW2, an FeII oxidoreductase involved in photoferrotrophy

    Pereira, L.; Saraiva, I. H.; Coelho, R.; Newman, D. K.; Louro, R. O.; Frazão, C.

    2012-01-01

    Crystals of the R. ferrooxidans SW2 iron oxidoreductase FoxE were obtained and the phase problem was solved by Fe SAD at 2.44 Å resolution. FoxE is a protein encoded by the foxEYZ operon of Rhodobacter ferrooxidans SW2 that is involved in Fe II -based anoxygenic photosynthesis (‘photoferrotrophy’). It is thought to reside in the periplasm, where it stimulates light-dependent Fe II oxidation. It contains 259 residues, including two haem c-binding motifs. As no three-dimensional model is available and there is no structure with a similar sequence, crystals of FoxE were produced. They diffracted to 2.44 Å resolution using synchrotron radiation at the Fe edge. The phase problem was solved by SAD using SHELXC/D/E and the experimental maps confirmed the presence of two haems per molecule

  8. Landscape genetics of the nonnative red fox of California.

    Sacks, Benjamin N; Brazeal, Jennifer L; Lewis, Jeffrey C

    2016-07-01

    Invasive mammalian carnivores contribute disproportionately to declines in global biodiversity. In California, nonnative red foxes (Vulpes vulpes) have significantly impacted endangered ground-nesting birds and native canids. These foxes derive primarily from captive-reared animals associated with the fur-farming industry. Over the past five decades, the cumulative area occupied by nonnative red fox increased to cover much of central and southern California. We used a landscape-genetic approach involving mitochondrial DNA (mtDNA) sequences and 13 microsatellites of 402 nonnative red foxes removed in predator control programs to investigate source populations, contemporary connectivity, and metapopulation dynamics. Both markers indicated high population structuring consistent with origins from multiple introductions and low subsequent gene flow. Landscape-genetic modeling indicated that population connectivity was especially low among coastal sampling sites surrounded by mountainous wildlands but somewhat higher through topographically flat, urban and agricultural landscapes. The genetic composition of populations tended to be stable for multiple generations, indicating a degree of demographic resilience to predator removal programs. However, in two sites where intensive predator control reduced fox abundance, we observed increases in immigration, suggesting potential for recolonization to counter eradication attempts. These findings, along with continued genetic monitoring, can help guide localized management of foxes by identifying points of introductions and routes of spread and evaluating the relative importance of reproduction and immigration in maintaining populations. More generally, the study illustrates the utility of a landscape-genetic approach for understanding invasion dynamics and metapopulation structure of one of the world's most destructive invasive mammals, the red fox.

  9. Comparative studies on testicular and epididymal morphology, and serum hormone concentrations in foxes and the hybrids during the breeding season.

    The silver fox and the blue fox belong to different genera, and the hybrid males are fully or partially sterile. In the present study, the objective was to evaluate the causes of hybrid male sterility, and therefore analyze the differences in testicular, and epididymal morphology and serum hormone concentrations among silver foxes, blue foxes, and the hybrids during the breeding season. Samples were collected from 20 male silver foxes, 20 male blue foxes, 15 male HSBs (silver fox female × blue fox male hybrids) and 14 male HBSs (blue fox male × silver fox female hybrids), respectively. Seminal evaluation showed large numbers of sperm present in the semen of blue foxes and silver foxes, but no sperm present in the hybrids. Mean testicular volume and the diameter of seminiferous tubules in silver foxes and blue foxes were greater than in the hybrids; and there were many Sertoli cells, spermatogenic cells, and sperm in silver foxes and blue foxes, while spermatogenic cells decreased with no sperm in the hybrids. Mean serum LH and prolactin concentrations in silver foxes and blue foxes were less and testosterone was greater than in the hybrids (P<0.05). The results indicate that germ cell meioses in the hybrids were arrested at the prophase stage of meiosis, and that lesser concentrations of testosterone and greater concentrations of LH and prolactin can inhibit the completion of spermatogenesis.

In 2012 the plant is expected to process 1003 tonnes for EDF and 12 tonnes for The Netherlands. AREVA has delivered to the CNNC Chinese company 700 fuel assemblies and 800 control rod clusters. The French Institute for Radioprotection and Nuclear Safety (IRSN) said that there was neither health nor environmental hazards on French soil due to the Fukushima accident. The French Academy of Sciences has highlighted the least sanitary impact of nuclear power compared to other energies. The American Nuclear Safety Association has stated that the American nuclear power plants are safe and that the probability of a severe accident is very low. A new study shows an excess of cases of leukemia near nuclear power stations in France. This study rests on very few statistical cases. An opinion survey in the United Kingdom shows that the construction of nuclear power stations is considered as the best investment in infrastructures. EDF has planned to recruit in 2012 about 6000 people essentially in the nuclear sector. The Netherlands government has given its consent for the construction of the high flux reactor Pallas on the Petten site, this reactor will replace the HFR whose lifetime is over 50 years. (A.C.)

    Full Text Available To provide convenience for the user that frequently read the news, a system to gather, classify, and provide news from several news websites in one place was needed. This system utilized a recommender system to provide only relevant news to the user. This research proposed a system architecture that used vector space model, and Rocchio relevance feedback to provide specific news recommendation to user’s feedback. The results are that the proposed system architecture can achieve the goal by using five levels of feedback from the user. However, the time needed to gather news is increasing exponentially in line with the number of terms gathered from articles.

  12. Expression of Fox genes in the cephalochordate Branchiostoma lanceolatum

    2015-07-01

    Full Text Available Forkhead box (Fox genes code for transcription factors that play important roles in different biological processes. They are found in a wide variety of organisms and appeared in unicellular eukaryotes. In metazoans, the gene family includes many members that can be subdivided into 24 classes. Cephalochordates are key organisms to understand the functional evolution of gene families in the chordate lineage due to their phylogenetic position as an early divergent chordate, their simple anatomy and genome structure. In the genome of the cephalochordate amphioxus Branchiostoma floridae, 32 Fox genes were identified, with at least one member for each of the classes that were present in the ancestor of bilaterians. In this work we describe the expression pattern of 13 of these genes during the embryonic development of the Mediterranean amphioxus, Branchiostoma lanceolatum. We found that FoxK and FoxM genes present an ubiquitous expression while all the others show specific expression patterns restricted to diverse embryonic territories. Many of these expression patterns are conserved with vertebrates, suggesting that the main functions of Fox genes in chordates were present in their common ancestor.

  13. Fox Den Disease: An Interesting Case Following Delayed Diagnosis.

    Stehr, Ryan C; Kim, Nicholas; LoGiudice, John A; Ludwig, Kirk

    2015-06-01

    Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues. This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a 53-year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks. Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation. Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis. With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated.

    Full Text Available Pediatric urology is a pediatric speciality dedicated to the diagnosis and treatment of congenital and acquired genitourinary tract diseases. It is a speciality that is rapidly changing, thanks to the technological development that has been emerging in recent years. There have been important diagnostic and therapeutic news.Congenital anomalies of the kidneys and urinary tract (CAKUT include various entities of structural malformations that result from defects in their morphogenesis. Clinical research and genetic studies on the origins of CAKUT are quickly evolving, with significant growth of high-quality research.Management goals of CAKUT include prevention of febrile urinary tract infections (UTIs in newborns and toddles and renal injury, while minimizing the morbidity of treatment and follow-up. Treatment options include observation with or without continuous antibiotic prophylaxis (CAP and surgical correction. Now, randomized controlled studies show that children with normal urinary tracts or low-grade vesicoureteral reflux (VUR do not benefit from prophylaxis.All children with known mechanical or functional obstructions of the urinary tract are considered to have UTI. Functional obstruction often results from lower urinary tract dysfunction (LUTD of either neurogenic or non-neurogenic origin and dilating VUR.The role of bladder and bowel dysfunction (BBD in children with UTI and the long-term risk of renal scarring have shed new light on treatment strategies. Often it is BBD, rather than reflux, that causes UTI in children older than 2 years.Pediatric urology has evolved in recent years, with a greater focus on bladder and renal function, minimally invasive treatment, evidence-based interventions, and guideline adherence. Other topics in pediatric urology include urinary incontinence in children with special needs and the use of robot-assisted laparoscopic surgery (RALS in children, with advantages over conventional laparoscopic surgery

  15. WHEN AND WHY DO HEDGEHOGS AND FOXES DIFFER?

    Keil, Frank C

    2010-01-01

    Philip E. Tetlock's finding that "hedgehog" experts (those with one big theory) are worse predictors than "foxes" (those with multiple, less comprehensive theories) offers fertile ground for future research. Are experts as likely to exhibit hedgehog- or fox-like tendencies in areas that call for explanatory, diagnostic, and skill-based expertise-as they did when Tetlock called on experts to make predictions? Do particular domains of expertise curtail or encourage different styles of expertise? Can we trace these different styles to childhood? Finally, can we nudge hedgehogs to be more like foxes? Current research can only grope at the answers to these questions, but they are essential to gauging the health of expert political judgment.

  16. Removing foxing stains from old paper at 157 nm

    Sarantopoulou, E.; Samardzija, Z.; Kobe, S.; Kollia, Z.; Cefalas, A.C.

    2003-01-01

    Using a molecular fluorine laser at 157 nm foxing stains were removed successfully from a 16th century old paper. Laser cleaning of stains and foxing from old paper manuscripts is far more effective at 157 nm in comparison to different wavelengths without leaving any yellowish after-effect on the paper. This is because at 157 nm illumination of old paper, complete bond breaking of all the organic molecules of the paper is taking place. Mass spectroscopy at 157 nm and for moderate laser intensities up to 1 mJ/cm 2 of old paper suffering from foxing indicate organic matter disintegration to small photofragments atomic, diatomic or triatomic, which are flying apart with supersonic speed. In addition high spatial resolution energy dispersive X-ray system (EDXS) analysis over the effected areas indicate the presence of iron, suggesting that biological activity is taking place preferentially in paper areas containing iron

  1. Red fox spatial characteristics in relation to waterfowl predation

    Sargeant, A.B.

    1972-01-01

    Radio-equipped red foxes (Vulpes vulpes) on the Cedar Creek area in Minnesota were spatially distributed, with individual families occupying well defined, nonoverlapping, contiguous territories. Territory boundaries often conformed to natural physical boundaries and appeared to be maintained through some nonaggressive behavior mechanism. Individual foxes traveled extensively throughout the family territory each night. Fox territories appeared to range from approximately 1 to 3 square miles in size, dependent largely on population density. Red foxes used a sequence of dens to rear their pups, and the amount and location of food remains at individual dens changed as the pups matured. The denning season was divided into pre-emergence, confined-use, and dispersed-use periods of 4 to 5 weeks each. Remains of adult waterfowl were collected at rearing dens on six townships in three ecologically different regions of eastern North Dakota. Remains of 172 adult dabbling ducks and 16 adult American coots (Fulica americana) were found at 35 dens. No remains from diving ducks were found. The number of adult ducks per den averaged 1.6, 5.9, and 10.2 for paired townships in regions with relatively low, moderate and high duck populations, respectively. Eighty-four percent of the ducks were females. The species and sex composition of ducks found at dens during early and late sampling periods reflected the nesting chronology of prairie dabbling ducks. Occupied rearing dens were focal points of red fox travel, and the locations of dens may have had considerable influence on predation. Thirty-five of 38 dens found on the six township study areas were on pastured or idle lands. The distribution of rearing dens on the Sand Lake and Arrowwood national wildlife refuges suggested that, on these areas, fox dens were concentrated because of the topography and land-use practices.

  2. News Consumption and Media Bias

    Yi Xiang; Miklos Sarvary

    2007-01-01

    Bias in the market for news is well-documented. Recent research in economics explains the phenomenon by assuming that consumers want to read (watch) news that is consistent with their tastes or prior beliefs rather than the truth. The present paper builds on this idea but recognizes that (i) besides “biased” consumers, there are also “conscientious” consumers whose sole interest is in discovering the truth, and (ii) consistent with reality, media bias is constrained by the truth. These two fa...

  2. Genetic signatures of adaptation revealed from transcriptome sequencing of Arctic and red foxes.

    Kumar, Vikas; Kutschera, Verena E; Nilsson, Maria A; Janke, Axel

    2015-08-07

    The genus Vulpes (true foxes) comprises numerous species that inhabit a wide range of habitats and climatic conditions, including one species, the Arctic fox (Vulpes lagopus) which is adapted to the arctic region. A close relative to the Arctic fox, the red fox (Vulpes vulpes), occurs in subarctic to subtropical habitats. To study the genetic basis of their adaptations to different environments, transcriptome sequences from two Arctic foxes and one red fox individual were generated and analyzed for signatures of positive selection. In addition, the data allowed for a phylogenetic analysis and divergence time estimate between the two fox species. The de novo assembly of reads resulted in more than 160,000 contigs/transcripts per individual. Approximately 17,000 homologous genes were identified using human and the non-redundant databases. Positive selection analyses revealed several genes involved in various metabolic and molecular processes such as energy metabolism, cardiac gene regulation, apoptosis and blood coagulation to be under positive selection in foxes. Branch site tests identified four genes to be under positive selection in the Arctic fox transcriptome, two of which are fat metabolism genes. In the red fox transcriptome eight genes are under positive selection, including molecular process genes, notably genes involved in ATP metabolism. Analysis of the three transcriptomes and five Sanger re-sequenced genes in additional individuals identified a lower genetic variability within Arctic foxes compared to red foxes, which is consistent with distribution range differences and demographic responses to past climatic fluctuations. A phylogenomic analysis estimated that the Arctic and red fox lineages diverged about three million years ago. Transcriptome data are an economic way to generate genomic resources for evolutionary studies. Despite not representing an entire genome, this transcriptome analysis identified numerous genes that are relevant to arctic

  4. Volcano surveillance by ACR silver fox

    Patterson, M.C.L.; Mulligair, A.; Douglas, J.; Robinson, J.; Pallister, J.S.

    2005-01-01

    Recent growth in the business of unmanned air vehicles (UAVs) both in the US and abroad has improved their overall capability, resulting in a reduction in cost, greater reliability and adoption into areas where they had previously not been considered. Uses in coastal and border patrol, forestry and agriculture have recently been evaluated in an effort to expand the observed area and reduce surveillance and reconnaissance costs for information gathering. The scientific community has both contributed and benefited greatly in this development. A larger suite of light-weight miniaturized sensors now exists for a range of applications which in turn has led to an increase in the gathering of information from these autonomous vehicles. In October 2004 the first eruption of Mount St Helens since 1986 caused tremendous interest amoUg people worldwide. Volcanologists at the U.S. Geological Survey rapidly ramped up the level of monitoring using a variety of ground-based sensors deployed in the crater and on the flanks of the volcano using manned helicopters. In order to develop additional unmanned sensing methods that can be used in potentially hazardous and low visibility conditions, a UAV experiment was conducted during the ongoing eruption early in November. The Silver Fox UAV was flown over and inside the crater to perform routine observation and data gathering, thereby demonstrating a technology that could reduce physical risk to scientists and other field operatives. It was demonstrated that UAVs can be flown autonomously at an active volcano and can deliver real time data to a remote location. Although still relatively limited in extent, these initial flights provided information on volcanic activity and thermal conditions within the crater and at the new (2004) lava dome. The flights demonstrated that readily available visual and infrared video sensors mounted in a small and relatively low-cost aerial platform can provide useful data on volcanic phenomena. This was

The transcriptional activity of most FoxO members is inhibitory to myogenic differentiation and overexpression of FoxO1 inhibits the development of oxidative type?I fibres in?vivo. In this study, we found that FoxO6, the last discovered FoxO family member, is expressed ubiquitously in various tissues but with higher e...

  13. Expression analysis of the speech-related genes FoxP1 and FoxP2 and their relation to singing behavior in two songbird species

    SUMMARY Humans and songbirds are among the rare animal groups that exhibit socially learned vocalizations: speech and song, respectively. These vocal-learning capacities share a reliance on audition and cortico-basal ganglia circuitry, as well as neurogenetic mechanisms. Notably, the transcription factors Forkhead box proteins 1 and 2 (FoxP1, FoxP2) exhibit similar expression patterns in the cortex and basal ganglia of humans and the zebra finch species of songbird, among other brain regions. Mutations in either gene are associated with language disorders in humans. Experimental knock-down of FoxP2 in the basal ganglia song control region Area X during song development leads to imprecise copying of tutor songs. Moreover, FoxP2 levels decrease naturally within Area X when zebra finches sing. Here, we examined neural expression patterns of FoxP1 and FoxP2 mRNA in adult Bengalese finches, a songbird species whose songs exhibit greater sequence complexity and increased reliance on audition for maintaining their quality. We found that FoxP1 and FoxP2 expression in Bengalese finches is similar to that in zebra finches, including strong mRNA signals for both factors in multiple song control nuclei and enhancement of FoxP1 in these regions relative to surrounding brain tissue. As with zebra finches, when Bengalese finches sing, FoxP2 is behaviorally downregulated within basal ganglia Area X over a similar time course, and expression negatively correlates with the amount of singing. This study confirms that in multiple songbird species, FoxP1 expression highlights song control regions, and regulation of FoxP2 is associated with motor control of song. PMID:24006346

  14. "Crashing the gates" - selection criteria for television news reporting of traffic crashes.

    De Ceunynck, Tim; De Smedt, Julie; Daniels, Stijn; Wouters, Ruud; Baets, Michèle

    2015-07-01

    This study investigates which crash characteristics influence the probability that the crash is reported in the television news. To this purpose, all news items from the period 2006-2012 about traffic crashes from the prime time news of two Belgian television channels are linked to the official injury crash database. Logistic regression models are built for the database of all injury crashes and for the subset of fatal crashes to identify crash characteristics that correlate with a lower or higher probability of being reported in the news. A number of significant biases in terms of crash severity, time, place, types of involved road users and victims' personal characteristics are found in the media reporting of crashes. More severe crashes are reported in the media more easily than less severe crashes. Significant fluctuations in media reporting probability through time are found in terms of the year and month in which the crash took place. Crashes during week days are generally less reported in the news. The geographical area (province) in which the crash takes place also has a significant impact on the probability of being reported in the news. Crashes on motorways are significantly more represented in the news. Regarding the age of the involved victims, a clear trend of higher media reporting rates of crashes involving young victims or young fatalities is observed. Crashes involving female fatalities are also more frequently reported in the news. Furthermore, crashes involving a bus have a significantly higher probability of being reported in the news, while crashes involving a motorcycle have a significantly lower probability. Some models also indicate a lower reporting rate of crashes involving a moped, and a higher reporting rate of crashes involving heavy goods vehicles. These biases in media reporting can create skewed perceptions in the general public about the prevalence of traffic crashes and eventually may influence people's behaviour. Copyright © 2015

  15. Spatial relations between sympatric coyotes and red foxes in North Dakota

    Sargeant, A.B.; Allen, S.H.; Hastings, J.O.

    1987-01-01

    Spatial relations between coyotes (Canis latrans) and red foxes (Vulpes vulpes) on a 360-km2 area in North Dakota were studied during 1977-78. Coyote families occupied large (mean = 61.2 km2), relatively exclusive territories that encompassed about one-half of the study area. Fox families occupied much smaller (mean = 11.9 km2), relatively exclusive, territories that overlapped perimeters of coyote territories and/or encompassed area unoccupied by coyotes. No fox family lived totally within a coyote territory, but 3 fox families lived within the 153.6-km2 home range of an unattached yearling male coyote. Both coyotes and foxes, from families with overlapping territories, tended to use their overlap areas less than was expected by amount of overlap. Encounters between radio-equipped coyotes and foxes from families with overlapping territories occurred less often than was expected by chance. Foxes living near coyotes exhibited considerable tenacity to their territories, and no monitored fox was killed by coyotes during 2,518 fox-days of radio surveillance. A hypothesis for coyote-induced fox population declines, based largely on fox avoidance mechanisms, is presented.

    A total of 6141 foxes (Vulpes vulpes) were examined for infection with Trichinella. The foxes were killed in Denmark during the hunting season 1995-1996 and 1997-1998; 3133 and 3008, respectively, Foxes included in the investigation came from throughout the country with the exception of the island...... of Bornholm. The right foreleg from each fox was submitted for investigation. The legs were stored at -20 degrees C for 3-10 months prior to examination. Following thawing, muscle tissue (10 g) from each leg was examined by trichinoscopy and by a pepsin-HCl digestion technique. In 1995-1996, three foxes were...... found positive corresponding to a prevalence of 0.001. Each of the infected foxes harboured an extremely low infection, i.e, about one larva per 10 g muscle tissue. It was not possible to obtain sufficient larval material for species identification, All three foxes were shot in the vicinity of a small...

    2015-02-01

    We determined the absolute hearing sensitivity of the red fox (Vulpes vulpes) using an adapted standard psychoacoustic procedure. The animals were tested in a reward-based go/no-go procedure in a semi-anechoic chamber. At 60 dB sound pressure level (SPL) (re 20 μPa) red foxes perceive pure tones between 51 Hz and 48 kHz, spanning 9.84 octaves with a single peak sensitivity of -15 dB at 4 kHz. The red foxes' high-frequency cutoff is comparable to that of the domestic dog while the low-frequency cutoff is comparable to that of the domestic cat and the absolute sensitivity is between both species. The maximal absolute sensitivity of the red fox is among the best found to date in any mammal. The procedure used here allows for assessment of animal auditory thresholds using positive reinforcement outside the laboratory. Copyright © 2014 Elsevier B.V. All rights reserved.

    Blastomyces dermatitidis, a fungus that can cause fatal infection in humans and other mammals, is not readily recoverable from soil, its environmental reservoir. Because of the red fox's widespread distribution, susceptibility to B. dermatitidis, close association with soil, and well-defined home ranges, this animal has potential utility as a sentinel for this fungus.

  5. Predation by Red Foxes (Vulpes vulpes at an Outdoor Piggery

    Patricia A. Fleming

    2016-10-01

    Full Text Available Outdoor pig operations are an alternative to intensive systems of raising pigs; however for the majority of outdoor pork producers, issues of biosecurity and predation control require significant management and (or capital investment. Identifying and quantifying predation risk in outdoor pork operations has rarely been done, but such data would be informative for these producers as part of their financial and logistical planning. We quantified potential impact of fox predation on piglets bred on an outdoor pork operation in south-western Australia. We used remote sensor cameras at select sites across the farm as well as above farrowing huts to record interactions between predators and pigs (sows and piglets. We also identified animal losses from breeding records, calculating weaning rate as a proportion of piglets born. Although only few piglets were recorded lost to fox predation (recorded by piggery staff as carcasses that are “chewed”, it is likely that foxes were contributing substantially to the 20% of piglets that were reported “missing”. Both sets of cameras recorded a high incidence of fox activity; foxes appeared on camera soon after staff left for the day, were observed tracking and taking live piglets (despite the presence of sows, and removed dead carcasses from in front of the cameras. Newly born and younger piglets appeared to be the most vulnerable, especially when they are born out in the paddock, but older piglets were also lost. A significant ( p = 0.001 effect of individual sow identification on the weaning rate, but no effect of sow age (parity, suggests that individual sow behavior towards predators influences predation risk for litters. We tracked the movement of piglet carcasses by foxes, and confirmed that foxes make use of patches of native vegetation for cover, although there was no effect of paddock, distance to vegetation, or position on the farm on weaning rate. Trials with non-toxic baits reveal high levels

    OBJECTIVE Excessive endogenous glucose production contributes to fasting hyperglycemia in diabetes. This effect stems from inept insulin suppression of hepatic gluconeogenesis. To understand the underlying mechanisms, we studied the ability of forkhead box O6 (FoxO6) to mediate insulin action on hepatic gluconeogenesis and its contribution to glucose metabolism. RESEARCH DESIGN AND METHODS We characterized FoxO6 in glucose metabolism in cultured hepatocytes and in rodent models of dietary obesity, insulin resistance, or insulin-deficient diabetes. We determined the effect of FoxO6 on hepatic gluconeogenesis in genetically modified mice with FoxO6 gain- versus loss-of-function and in diabetic db/db mice with selective FoxO6 ablation in the liver. RESULTS FoxO6 integrates insulin signaling to hepatic gluconeogenesis. In mice, elevated FoxO6 activity in the liver augments gluconeogenesis, raising fasting blood glucose levels, and hepatic FoxO6 depletion suppresses gluconeogenesis, resulting in fasting hypoglycemia. FoxO6 stimulates gluconeogenesis, which is counteracted by insulin. Insulin inhibits FoxO6 activity via a distinct mechanism by inducing its phosphorylation and disabling its transcriptional activity, without altering its subcellular distribution in hepatocytes. FoxO6 becomes deregulated in the insulin-resistant liver, accounting for its unbridled activity in promoting gluconeogenesis and correlating with the pathogenesis of fasting hyperglycemia in diabetes. These metabolic abnormalities, along with fasting hyperglycemia, are reversible by selective inhibition of hepatic FoxO6 activity in diabetic mice. CONCLUSIONS Our data uncover a FoxO6-dependent pathway by which the liver orchestrates insulin regulation of gluconeogenesis, providing the proof-of-concept that selective FoxO6 inhibition is beneficial for curbing excessive hepatic glucose production and improving glycemic control in diabetes.

    A meiotic linkage map is essential for mapping traits of interest and is often the first step toward understanding a cryptic genome. Specific strains of silver fox (a variant of the red fox, Vulpes vulpes), which segregate behavioral and morphological phenotypes, create a need for such a map. One such strain, selected for docility, exhibits friendly dog-like responses to humans, in contrast to another strain selected for aggression. Development of a fox map is facilitated by the known cytogenetic homologies between the dog and fox, and by the availability of high resolution canine genome maps and sequence data. Furthermore, the high genomic sequence identity between dog and fox allows adaptation of canine microsatellites for genotyping and meiotic mapping in foxes. Using 320 such markers, we have constructed the first meiotic linkage map of the fox genome. The resulting sex-averaged map covers 16 fox autosomes and the X chromosome with an average inter-marker distance of 7.5 cM. The total map length corresponds to 1480.2 cM. From comparison of sex-averaged meiotic linkage maps of the fox and dog genomes, suppression of recombination in pericentromeric regions of the metacentric fox chromosomes was apparent, relative to the corresponding segments of acrocentric dog chromosomes. Alignment of the fox meiotic map against the 7.6x canine genome sequence revealed high conservation of marker order between homologous regions of the two species. The fox meiotic map provides a critical tool for genetic studies in foxes and identification of genetic loci and genes implicated in fox domestication.

    2014-08-29

    Forty wild canids including 31 golden jackals (Canis aureus Linné, 1758) and 9 red foxes (Vulpes vulpes Linné, 1758) collected between 2008 and 2011 in the northeast, northwest and center of Tunisia were necropsied and examined for intestinal helminth parasites. All jackals and foxes were found infected with a prevalence rate of 95% for cestodes, 82.5% for nematodes and 7.5% for acanthocephalans. A total of twelve helminth species were recorded in red foxes: cestodes, Dipylidium caninum (55.6%), Diplopylidium noelleri (55.6%), Mesocestoïdes lineatus (55.6%), Mesocestoïdes litteratus (33%), Mesocestoïdes corti (22%); nematodes, Ancylostoma caninum (11%), Uncinaria stenocephala (44%), Spirura rytipleurites (11%), Trichuris vulpis (33%), Pterygodermatites affinis (67%), Oxynema linstowi (33%) and the acanthocephalan Macracanthorhynchus hirudinaceus (22%). The fifteen recovered helminth species in jackals were Echinococcus granulosus (9.7%), D. caninum (16%), D. noelleri (16%), M. lineatus (74%), M. litteratus (23%), M. corti (12.9%), Taenia pisiformis (3.2%), Taenia spp. (19%), Toxocara canis (16%), Toxascaris leonina (6.5%), A. caninum (9.7%), U. stenocephala (68%), P. affinis (6.5%), O. linstowi (3.2%) and Macracanthorhynchus hirudinaceus (3.2%). This is the first report on the presence of P. affinis, D. noelleri and O. linstowi in Tunisia. E. granulosus was found in young jackals, aged less than 4 years old, with a higher abundance in females (8.9 worms). M. lineatus presented the highest mean intensity of 231.86 and 108.8 tapeworms respectively in jackals and foxes. Canids from the northwest region had the highest prevalence (77.5%) and highest intensity (243.7) of helminth species compared to those from the northeast and central areas. U. stenocephala and O. linstowi had the highest mean intensity for nematodes in both jackals and foxes at 14.3 and 88 worms respectively. Copyright © 2014 Elsevier B.V. All rights reserved.

  13. Immobilization of swift foxes with ketamine hydrochloride-xylazine hydrochloride

    2002-01-01

    There is an increasing need to develop field immobilization techniques that allow researchers to handle safely swift foxes (Vulpes velox) with minimal risk of stress or injury. We immobilized captive swift foxes to determine the safety and effectiveness of ketamine hydrochloride and xylazine hydrochloride at different dosages. We attempted to determine appropriate dosages to immobilize swift foxes for an adequate field-handling period based on three anesthesia intervals (induction period, immobilization period, and recovery period) and physiologic responses (rectal temperature, respiration rate, and heart rate). Between October 1998–July 1999, we conducted four trials, evaluating three different dosage ratios of ketamine and xylazine (2.27:1.2, 5.68:1.2, and 11.4:1.2 mg/kg ketamine:mg/kg xylazine, respectively), followed by a fourth trial with a higher dosage at the median ratio (11.4 mg/kg ketamine:2.4 mg/kg xylazine). We found little difference in induction and recovery periods among trials 1–3, but immobilization time increased with increasing dosage (Pimmobilization period and recovery period increased in trial 4 compared with trials 1–3 (P≤0.03). There was a high variation in responses of individual foxes across trials, making it difficult to identify an appropriate dosage for field handling. Heart rate and respiration rates were depressed but all physiologic measures remained within normal parameters established for domestic canids. We recommend a dosage ratio of 10 mg/kg ketamine to 1 mg/kg xylazine to immobilize swift foxes for field handling.

  17. What does the fox say? Monitoring antimicrobial resistance in the environment using wild red foxes as an indicator.

    Solveig Sølverød Mo

    Full Text Available The objective of this study was to estimate and compare the occurrence of AMR in wild red foxes in relation to human population densities. Samples from wild red foxes (n = 528 included in the Norwegian monitoring programme on antimicrobial resistance in bacteria from food, feed and animals were included. All samples were divided into three different groups based on population density in the municipality where the foxes were hunted. Of the 528 samples included, 108 (20.5%, 328 (62.1% and 92 (17.4% originated from areas with low, medium and high population density, respectively. A single faecal swab was collected from each fox. All samples were plated out on a selective medium for Enterobacteriaceae for culturing followed by inclusion and susceptibility testing of one randomly selected Escherichia coli to assess the overall occurrence of AMR in the Gram-negative bacterial population. Furthermore, the samples were subjected to selective screening for detection of E. coli displaying resistance towards extended-spectrum cephalosporins and fluoroquinolones. In addition, a subset of samples (n = 387 were subjected to selective culturing to detect E. coli resistant to carbapenems and colistin, and enterococci resistant to vancomycin. Of these, 98 (25.3%, 200 (51.7% and 89 (23.0% originated from areas with low, medium and high population density, respectively. Overall, the occurrence of AMR in indicator E. coli from wild red foxes originating from areas with different human population densities in Norway was low to moderate (8.8%. The total occurrence of AMR was significantly higher; χ2 (1,N = 336 = 6.53, p = 0.01 in areas with high population density compared to areas with medium population density. Similarly, the occurrence of fluoroquinolone resistant E. coli isolated using selective detection methods was low in areas with low population density and more common in areas with medium or high population density. In conclusion, we found indications that

    1998 ACS Meeting in Boston he suffered a serious fall following a stroke, from which he never recovered. One of his last photographs, taken the previous day at a Journal luncheon, appears on page 1360 of the November 1998 issue. His commentary on his long career in chemistry and education appears on page 1520 of the December 1998 issue. Seaborg was a Nobel laureate, discoverer of elements, scientific advisor to presidents, former chancellor of the University of California, former chairman of the Atomic Energy Commission, chairman of the steering committee of the CHEM Study project, founder of Lawrence Hall of Science, , the list goes on and on. He was at the same time a passionate supporter of education. Seaborg published fourteen articles in the Journal between 1951 and 1998. He was interviewed in 1975 by David Ridgway as part of the Impact series (JCE 1975, 52, 70), and that interview is highly recommended reading (see supplement to this article). He received the 1994 ACS George C. Pimentel Award in Chemical Education; his award address was published in the ACS Division of Chemical Education's CHED Newsletter, Fall 1995. Memorial articles with details of his life and his scientific contributions have appeared in The New York Times (Saturday, February 27, 1999, page 1) and Chemical & Engineering News (March 8, 1999, page 29). But there is also the spirit of the man, what he believed in, what he tried to do, what he hoped he had accomplished. A sense of that can be gained from the excerpts that are reprinted below, taken first from the Impact interview and then from the award address. Ridgway: On reflection, now, out of your many contributions to chemistry, is there one that you feel has had more of an impact than others? Seaborg: The discovery of plutonium would answer that question. The impact there is probably nearly as great as any single chemical discovery. Ridgway: What was the state of the "art" in your field when you first decided to bend your energies in this

  20. Asymmetric News Effects on Volatility: Good vs. Bad News in Good vs. Bad Times

    Laakkonen, Helinä; Lanne, Markku

    2008-01-01

    We study the impact of positive and negative macroeconomic US and European news announcements in different phases of the business cycle on the highfrequency volatility of the EUR/USD exchange rate. The results suggest that in general bad news increases volatility more than good news. The news effects also depend on the state of the economy: bad news increases volatility more in good times than in bad times, while there is no difference between the volatility effects of good news in bad and go...

  1. Delivering bad news in emergency care medicine.

    Maynard, Douglas W

    2017-01-01

    Forecasting is a strategy for delivering bad news and is compared to two other strategies, stalling and being blunt. Forecasting provides some warning that bad news is forthcoming without keeping the recipient in a state of indefinite suspense (stalling) or conveying the news abruptly (being blunt). Forecasting appears to be more effective than stalling or being blunt in helping a recipient to "realize" the bad news because it involves the deliverer and recipient in a particular social relation. The deliverer of bad news initiates the telling by giving an advance indication of the bad news to come; this allows the recipient to calculate the news in advance of its final presentation, when the deliverer confirms what the recipient has been led to anticipate. Thus, realization of bad news emerges from intimate collaboration, whereas stalling and being blunt require recipients to apprehend the news in a social vacuum. Exacerbating disruption to recipients' everyday world, stalling and being blunt increase the probability of misapprehension (denying, blaming, taking the situation as a joke, etc.) and thereby inhibit rather than facilitate realization. Particular attention is paid to the "perspective display sequence", a particular forecasting strategy that enables both confirming the recipient's perspective and using that perspective to affirm the clinical news. An example from acute or emergency medicine is examined at the close of the paper.

  2. News clippings for introductory astronomy

    Bobrowsky, Matthew

    1999-09-01

    Most students entering our introductory astronomy course for nonscience majors arrive not merely lacking scientific facts-they also have misconceptions about the nature of science, and many have a handicapping ``science anxiety'' (in addition to math anxiety). So I have added a ``current science'' requirement to our introductory course. Each student must compile a file of five astronomy news articles taken from readily available sources.

  3. FoxA1 binding to the MMTV LTR modulates chromatin structure and transcription

    Holmqvist, Per-Henrik; Belikov, Sergey; Zaret, Kenneth S.; Wrange, Oerjan

    2005-01-01

    Novel binding sites for the forkhead transcription factor family member Forkhead box A (FoxA), previously referred to as Hepatocyte Nuclear Factor 3 (HNF3), were found within the mouse mammary tumor virus long terminal repeat (MMTV LTR). The effect of FoxA1 on MMTV LTR chromatin structure, and expression was evaluated in Xenopus laevis oocytes. Mutagenesis of either of the two main FoxA binding sites showed that the distal site, -232/-221, conferred FoxA1-dependent partial inhibition of glucocorticoid receptor (GR) driven MMTV transcription. The proximal FoxA binding segment consisted of two individual FoxA sites at -57/-46 and -45/-34, respectively, that mediated an increased basal MMTV transcription. FoxA1 binding altered the chromatin structure of both the inactive- and the hormone-activated MMTV LTR. Hydroxyl radical foot printing revealed FoxA1-mediated changes in the nucleosome arrangement. Micrococcal nuclease digestion showed the hormone-dependent sub-nucleosome complex, containing ∼120 bp of DNA, to be expanded by FoxA1 binding to the proximal segment into a larger complex containing ∼200 bp. The potential function of the FoxA1-mediated expression of the MMTV provirus for maintenance of expression in different tissues is discussed

  4. Syntheses and Thermal Behaviors of Rb(FOX-7)·H2O and Cs(FOX-7)·H2O

    Luo, Jinan; Xu, Kangzhen; Wang, Min; Ren, Xiaolei; Chen, Yongshun; Song, Jirong; Zhao, Fengqi

    2010-01-01

    Two new energetic organic alkali metal salts, 1,1-diamino-2,2-dinitroethylene rubidium salt [Rb(FOX-7)·H 2 O] and 1,1- diamino-2,2-dinitroethylene cesium salt [Cs(FOX-7)·H 2 O], were synthesized by reacting of 1,1-diamino-2,2-dinitroethylene (FOX-7) and rubidium chloride or cesium chloride in alkali methanol aqueous solution, respectively. The thermal behaviors of Rb(FOX-7)·H 2 O and Cs(FOX-7)·H 2 O were studied with DSC and TG methods. The critical temperatures of thermal explosion of the two compounds are 216.22 and 223.73 .deg. C, respectively. Specific heat capacities of the two compounds were determined with a micro-DSC method, and the molar heat capacities are 217.46 and 199.47 J mol -1 K -1 at 298.15 K, respectively. The adiabatic times-to-explosion were also calculated to be a certain value of 5.81 - 6.36 s for Rb(FOX-7)·H 2 O, and 9.92 - 10.54 s for Cs(FOX-7)·H 2 O. After FOX-7 becoming alkali metal salts, thermal decomposition temperatures of the compounds heighten with the rise of element period, but thermal decomposition processes become intense

  5. For Video Games, Bad News Is Good News: News Reporting of Violent Video Game Studies.

    Copenhaver, Allen; Mitrofan, Oana; Ferguson, Christopher J

    2017-12-01

    News coverage of video game violence studies has been critiqued for focusing mainly on studies supporting negative effects and failing to report studies that did not find evidence for such effects. These concerns were tested in a sample of 68 published studies using child and adolescent samples. Contrary to our hypotheses, study effect size was not a predictor of either newspaper coverage or publication in journals with a high-impact factor. However, a relationship between poorer study quality and newspaper coverage approached significance. High-impact journals were not found to publish studies with higher quality. Poorer quality studies, which tended to highlight negative findings, also received more citations in scholarly sources. Our findings suggest that negative effects of violent video games exposure in children and adolescents, rather than large effect size or high methodological quality, increase the likelihood of a study being cited in other academic publications and subsequently receiving news media coverage.

  6. Giving bad news: a qualitative research exploration.

    Aein, Fereshteh; Delaram, Masoumeh

    2014-06-01

    The manner in which healthcare professionals deliver bad news affects the way it is received, interpreted, understood, and dealt with. Despite the fact that clinicians are responsible for breaking bad news, it has been shown that they lack skills necessary to perform this task. The purpose of this study was to explore Iranian mothers' experiences to receive bad news about their children cancer and to summarize suggestions for improving delivering bad news by healthcare providers. A qualitative approach using content analysis was adopted. Semi-structured interviews were conducted with 14 mothers from two pediatric hospitals in Iran. Five major categories emerged from the data analysis, including dumping information, shock and upset, emotional work, burden of delivering bad news to the family members, and a room for multidisciplinary approach. Effective communication of healthcare team with mothers is required during breaking bad news. Using multidisciplinary approaches to prevent harmful reactions and providing appropriate support are recommended.

  7. The Changing Landscape of Science News

    Riordon, James

    2011-03-01

    Social media are revolutionizing the ways that people communicate and the ways they get their news. Traditional news outlets are in decline, and no subject area is declining faster than science news. Every day there are fewer professional science journalists working in traditional media. On the other hand, ever greater numbers of scientists, science enthusiasts, and online journalists are turning to blogs, podcasts, eBooks, twitter feeds, and social media sites like Facebook and Tumbler to spread news about science. I will present an overview of the state of science journalism and speculate on the likely directions it seems to be heading. I will also offer some general guidelines to help scientists understand what makes a good science news story, as well as suggesting ways that they can get their work in the news.

  10. The Cognitive Information Effect of Televised News.

    Lăzăroiu, George; Pera, Aurel; Ştefănescu-Mihăilă, Ramona O; Bratu, Sofia; Mircică, Nela

    2017-01-01

    The purpose of this review is to summarize the key findings which prove that the biased perceptions of viewers may provide an inaccurate image of the informational validity of televised news. The news may generate distorted recollections of what occurred in particular reported events if displayed routines influence viewers not to pay attention to the essential features of a narrative. Elaborating on Fiske and Hartley (2010), Zelizer (2010), and Gunter (2015), we indicate that the character of the news setting has altered and individuals' news consumption routines have changed in adapting to media advancements. The news may be undergone at various psychological stages by news publics. Televised news may transmit information undeviatingly to publics that may (not) be committed successfully to memory. Our paper shows that individuals' skills to handle information that is displayed in a linguistic configuration are influenced by their abilities in the utilization of certain symbol systems that are employed to represent notions and meanings. Televised news may shape what individuals grasp, influence their perceptions, convictions, and views regarding prevailing events and matters, and transmit knowledge and interpretation. If news stories can be jotted down in a linguistic style that sidesteps making needless processing demands and captivate news users by facilitating them to make connections with former knowledge, they may be more worthy of note and more edifying. We conclude that news narratives present a cognitive demanding task to individuals, displaying novel information regarding evolving events in a multifarious format. Broadcast news exhibits intricate contents, displaying configurations that employ excessively the cognitive abilities for information processing of viewers.

  12. The Stock Market's Reaction to Unemployment News: Why Bad News is Usually Good for Stocks

    John H. Boyd; Ravi Jagannathan; Jian Hu

    2001-01-01

    We find that on average an announcement of rising unemployment is 'good news' for stocks during economic expansions and 'bad news' during economic contractions. Thus stock prices usually increase on news of rising unemployment, since the economy is usually in an expansion phase. We provide an explanation for this phenomenon. Unemployment news bundles two primitive types of information relevant for valuing stocks: information about future interest rates and future corporate earnings and divide...

  13. Canine distemper virus infection in fennec fox (Vulpes zerda).

    Woo, Gye-Hyeong; Jho, Yeon-Sook; Bak, Eun-Jung

    2010-08-01

    Fifteen 8-month-old fennec foxes imported from Sudan showed fever, mucopurulent ocular discharge, diarrhea, severe emaciation, seizures, and generalized ataxia, and died. Three of the 15 animals were presented for diagnostic investigation. Severe dehydration, brain congestion, and gastric ulcers were observed in all animals. In one animal, the lungs had failed to collapse and were multifocally dark red in appearance. Histopathologically, there were lymphohistiocytic meningoencephalitis with malacia, mild interstitial pneumonia, lymphoid depletion of lymphoid tissues and organs, and intestinal villous atrophy with intralesional coccidia. There were many intracytoplasmic and/or intranuclear inclusion bodies in the epithelial cells of the medullary velum, lungs, liver, kidneys, trachea, pancreas, stomach, gall bladder, urinary bladder, and ureters, and in macrophages of malacia foci and lymphocytes and macrophages of lymphoid organs. Additionally, intestinal coccidia were confirmed to be Isospora species by a fecal test. To our knowledge, this is the first report of canine distemper with intestinal coccidiosis in fennec fox.

  14. Lafora's-like disease in a fennec fox (Vulpes zerda).

    Honnold, Shelley P; Schulman, F Yvonne; Bauman, Karen; Nelson, Kevin

    2010-09-01

    A 6-yr-old captive-born female fennec fox (Vulpes zerda) had a history of multiple seizures and was treated with diazepam and phenobarbital therapy. Despite medical treatment, the seizures continued. They were intermittent and progressive, resulting in neurologic deficits and death of the animal within 6 mo of onset of the clinical signs. At necropsy, the animal was in good nutritional condition, and no gross lesions were noted in the brain. Histologically, amphophilic to basophilic, periodic acid-Schiff (PAS) positive, diastase-resistant inclusions were present in the brain, heart, and liver. Ultrastructurally, the inclusions were variably electron dense, fibrillary to occasionally granular, and non-membrane bound. The clinical, histologic, and ultrastructural findings were consistent with Lafora's disease, which in humans is a rare, fatal, autosomal recessive hereditary neurometabolic disorder characterized by progressive myoclonic epilepsy. This is the first report of Lafora's-like disease in a fennec fox.

  15. Foraging ecology and spatial behavior of the red fox (Vulpes vulpes) in a wet grassland ecosystem

    Meisner, Katrine; Sunde, Peter; Clausen, Kevin Kuhlmann

    2014-01-01

    We investigated diet composition, habitat selection and spatial behaviour of the red fox (Vulpes vulpes) in relation to the availability of wader nests in a coastal polder area in southwest Denmark. The predatory role of the red fox in wet grassland ecosystems has profound implications...... for conservation status of declining populations of grassland breeding waders. However, few studies have focussed on the foraging ecology and behaviour of the red fox in these landscapes. Faecal analyses revealed that fox diet consisted of birds (43 % of prey remains / 32 % of biomass), rodents (39 % / 21...... %), sheep (mainly as carrion, 14 % / 41 %) and lagomorphs (4 % / 7 %). Charadriiformes (including waders) comprised 3–12 % of prey remains throughout the year. Telemetry data and spotlight counts indicated that foxes did not select areas with high densities of breeding waders, suggesting that foxes did...

  16. Lattice Three-Species Models of the Spatial Spread of Rabies among FOXES

    Benyoussef, A.; Boccara, N.; Chakib, H.; Ez-Zahraouy, H.

    Lattice models describing the spatial spread of rabies among foxes are studied. In these models, the fox population is divided into three-species: susceptible (S), infected or incubating (I), and infectious or rabid (R). They are based on the fact that susceptible and incubating foxes are territorial while rabid foxes have lost their sense of direction and move erratically. Two different models are investigated: a one-dimensional coupled-map lattice model, and a two-dimensional automata network model. Both models take into account the short-range character of the infection process and the diffusive motion of rabid foxes. Numerical simulations show how the spatial distribution of rabies, and the speed of propagation of the epizootic front depend upon the carrying capacity of the environment and diffusion of rabid foxes out of their territory.

  19. Analysis of the Structure and Function of FOX-4 Cephamycinase.

    2016-02-01

    Class C β-lactamases poorly hydrolyze cephamycins (e.g., cefoxitin, cefotetan, and moxalactam). In the past 2 decades, a new family of plasmid-based AmpC β-lactamases conferring resistance to cefoxitin, the FOX family, has grown to include nine unique members descended from the Aeromonas caviae chromosomal AmpC. To understand the basis for the unique cephamycinase activity in the FOX family, we determined the first X-ray crystal structures of FOX-4, apo enzyme and the acyl-enzyme with its namesake compound, cefoxitin, using the Y150F deacylation-deficient variant. Notably, recombinant expression of N-terminally tagged FOX-4 also yielded an inactive adenylylated enzyme form not previously observed in β-lactamases. The posttranslational modification (PTM), which occurs on the active site Ser64, would not seem to provide a selective advantage, yet might present an opportunity for the design of novel antibacterial drugs. Substantial ligand-induced changes in the enzyme are seen in the acyl-enzyme complex, particularly the R2 loop and helix H10 (P289 to N297), with movement of F293 by 10.3 Å. Taken together, this study provides the first picture of this highly proficient class C cephamycinase, uncovers a novel PTM, and suggests a possible cephamycin resistance mechanism involving repositioning of the substrate due to the presence of S153P, N289P, and N346I substitutions in the ligand binding pocket.

  5. Spontaneous rickets in the wild arctic fox Alopex lagopus

    Ogden, J.A.; Conlogue, G.J.

    1981-01-01

    Normal and rachitic, skeletally immature arctic foxes (Alopex lagopus) were subjected to physical examination, roentgenographic studies, and in some cases histologic studies. The involved animals had active rickets coupled with antecedent normal diaphyseal bone formation. Evaluation of all the long bones showed highly variable manifestations of the disease, which undoubtedly reflect different rates of physeal endochondral transformation and metaphyseal remodeling. Histologic examination showed distinct patterns of widening of the physes and variable osteodystrophy in the trabecular and cortical bone of the metaphyses and epiphyseal ossification centers. These aforementioned factors certainly would necessitate different regional calcium needs and, therefore, different regional responses to an overall calcium deficiency. The physes involved in the most rapid growth rates in this period showed the most widening of the growth plate, and the most dystrophic changes in the metaphysis. Skeletal injuries, including metaphyseal fractures and slow-down of longitudinal growth (particularly in the ulna) were also evident. Because of apparent dietary differences in the affected and normal fox kits, this juvenile-onset disease was presumed due to calcium-deficient intake following weaning. To the best of our knowledge this is the first report of spontaneously occurring rickets in a wild animal in its natural habitat. There are several possible mechanisms for the variable widening of the physis and the loss of bone mineralization in these fox kits: calcium-deficient diet, binding of calcium in the bowel by high phosphorus intake, secondary hyperparathyroidism, and vitamin A toxicity.

  6. Red fox prey demands and implications to prairie duck production

    Sargeant, A.B.

    1978-01-01

    Experiments were conducted during spring and summer with 33 red foxes (Vulpes vulpes) to determine prey demands, feeding characteristics, and growth rates using natural foods. Pups began eating prey the 4th week after birth. Then, prey consumption averaged 1.38 and 1.90 kg/pup/week for weeks 5-8 and 9-12 of the denning season respectively, and 2.54 kg/pup/week for the postdenning period. Feeding by adults averaged 2.25 kg/adult/week. Free water was not needed by either pups or adults. About 90 percent of the prey offered to pups on simulated natural diets was consumed, remains varied with prey availability and prey type. Prey biomass required by a typical fox family was estimated at 18.5 kg/km2 for the 12-week denning season and 2.4 kg/km2/week for the postdenning period. Because of the large prey demands, ducks could represent a small part of the foxes' diet and yet be of consequence to the productivity of particular species. An example is provided for the mallard (Anas platyrhynchos).

  7. Molecular Mechanisms in the shock induced decomposition of FOX-7

    Mishra, Ankit; Tiwari, Subodh C.; Nakano, Aiichiro; Vashishta, Priya; Kalia, Rajiv; CACS Team

    Experimental and first principle computational studies on FOX 7 have either involved a very small system consisting of a few atoms or they did not take into account the decomposition mechanisms under extreme conditions of temperature and pressure. We have performed a large-scale reactive MD simulation using ReaxFF-lg force field to study the shock decomposition of FOX 7. The chemical composition of the principal decomposition products correlates well with experimental observations. Furthermore, we observed that the production of N2 and H2O was inter molecular in nature and was through different chemical pathways. Moreover, the production of CO and CO2 was delayed due to production of large stable C,O atoms cluster. These critical insights into the initial processes involved in the shock induced decomposition of FOX-7 will greatly help in understanding the factors playing an important role in the insensitiveness of this high energy material.

    Rural mail-carrier sightings of red foxes (Vulpes vulpes) during mid-April, -July, and -September of 1969-73 were compared to spring fox family estimates derived by aerial searches of six townships. The mid-April mail-carrier index reflected annual fox density changes on the six townships (correlation coefficient = 0.958) . Random exclusions of individual mail-carrier reports indicated participation could decline 40 percent without affecting index accuracy.

    A meiotic linkage map is essential for mapping traits of interest and is often the first step toward understanding a cryptic genome. Specific strains of silver fox (a variant of the red fox, Vulpes vulpes), which segregate behavioral and morphological phenotypes, create a need for such a map.

  11. AB126. Association between FOX03A gene polymorphisms and human longevity: a meta-analysis

    Zhao, Shanchao; Bao, Jiming; Song, Xianlu

    2016-01-01

    Objective Numerous studies have shown associations between the FOX03A gene, encoding the forkhead box 03 transcription factor, and human or specifically male longevity. However, the associations of specific FOX03A polymorphisms with longevity remain inconclusive. We performed a meta-analysis of existing studies to clarify these potential associations. Methods A comprehensive search was conducted to identify studies of FOX03A gene polymorphisms and longevity. Pooled odds ratios (ORs) and 95% c...

    Lledó, Lourdes; Serrano, José Luis; Isabel Gegúndez, María; Giménez-Pardo, Consuelo; Saz, José Vicente

    2016-01-01

    We examined 314 red foxes (Vulpes vulpes) from the province of Soria, Spain, for Rickettsia typhi, Rickettsia slovaca, and Borrelia burgdorferi infection. Immunofluorescence assays showed 1.9% had antibodies to R. typhi, 6.7% had antibodies to R. slovaca, and 8.3% had antibodies to B. burgdorferi. Serostatus was not correlated with sex or age. Because red foxes can be infected by Rickettsiae and B. burgdorferi, presence of red foxes may be and indicator for the presence of these pathogens.

  13. Tech Transfer News. Volume 6, No. 1

    Victor, Megan E.

    2014-01-01

    On October 28, 2011, the White House released a Presidential Memorandum entitled: Accelerating Technology Transfer and Commercialization of Federal Research in Support of High-Growth Businesses. With this memo, the President challenged all federal agencies conducting R&D to accelerate technology transfer and commercialization of federally developed technology to help stimulate the national economy. The NASA Technology Transfer Program responded by asking the center technology transfer offices to reach out to - and work more closely with - their regional economic development organizations to promote the transfer of NASA technologies to the local private sector for use in the marketplace. Toward that effort, the KSC Technology Transfer Office teamed with the Florida Space Coast Economic Development Commission (EDC) to host a technology transfer forum designed to increase our business community's awareness of available KSC technologies for transfer. In addition, the forum provided opportunities for commercial businesses to collaborate with KSC in technology development. (see article on page 12) The forum, held on September 12, 2013, focused on KSC technology transfer and partnership opportunities within the Robotics, Sustainability, Information Technology and Environmental Remediation technology areas. The event was well attended with over 120 business leaders from the community. KSC Center Director Robert Cabana and the Center Chief Technologist Karen Thompson provided remarks, and several KSC lead researchers presented technical information and answered questions, which were not in short supply. Florida Today and the Orlando Sentinel ran news stories on the forum and both NASA TV and Channel 6 News filmed portions of the event. Given the reaction by the media and local business to the forum, it is evident the community is recognizing the opportunities that NASA-developed technologies can provide to aspiring entrepreneurs and existing companies to bring new

  18. Phylogenetic relationships of the Fox (Forkhead) gene family in the Bilateria

    Mazet, Francoise; Yu, Jr Kai; Liberles, David A.; Holland, Linda Z.; Shimeld, Sebastian M.

    2003-01-01

    The Forkhead or Fox gene family encodes putative transcription factors. There are at least four Fox genes in yeast, 16 in Drosophila melanogaster (Dm) and 42 in humans. Recently, vertebrate Fox genes have been classified into 17 groups named FoxA to FoxQ. Here, we extend this analysis to invertebrates, using available sequences from D. melanogaster, Anopheles gambiae (Ag), Caenorhabditis elegans (Ce), the sea squirt Ciona intestinalis (Ci) and amphioxus Branchiostoma floridae (Bf), from which we also cloned several Fox genes. Phylogenetic analyses lend support to the previous overall subclassification of vertebrate genes, but suggest that four subclasses (FoxJ, L, N and Q) could be further subdivided to reflect their relationships to invertebrate genes. We were unable to identify orthologs of Fox subclasses E, H, I, J, M and Q1 in D. melanogaster, A. gambiae or C. elegans, suggesting either considerable loss in ecdysozoans or the evolution of these subclasses in the deuterostome lineage. Our analyses suggest that the common ancestor of protostomes and deuterostomes had a minimum complement of 14 Fox genes.

  19. A Multiplex PCR assay to differentiate between dog and red fox.

    Weissenberger, M; Reichert, W; Mattern, R

    2011-11-01

    Foxes are frequently the cause of car accidents in Baden-Württemberg (BW, Germany). The domestic dog (Canis familiaris) is in close relation to the red fox (Vulpes vulpes) and the silver fox which is a coat colour variant of the red fox. As insurance claims that involve accidents with animals require authentication, we analyzed frequency distribution and allele sizes in two canine microsatellite loci in 26 dogs (different breeds) and 19 red foxes of the region of BW, Germany. Moreover, sequencing analysis was performed. Red foxes exhibited only 1 allele at each microsatellite locus, whereas in dog 7 alleles at the CPH4 locus and 6 alleles at the CPH12 locus were detected. Sequences of PCR products from the two species revealed several differences between dogs and foxes. We established a sequenced allelic ladder and give population data from dogs and red foxes from the region of BW, Germany. Using microsatellite polymorphisms is efficient in differentiating between dogs and foxes in forensic casework. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    This study investigated the expression of genes in cashmere goats at different periods of their fetal development. Bioinformatics analysis was used to evaluate data obtained by transcriptome sequencing of fetus skin samples collected from Inner Mongolia cashmere goats on days 45, 55, and 65 of fetal age. We found that FoxN1 , FoxE1 , and FoxI3 genes of the Fox gene family were probably involved in the growth and development of the follicle and the formation of hair, which is consistent with previous findings. Real-time quantitative polymerase chain reaction detecting system and Western blot analysis were employed to study the relative differentially expressed genes FoxN1 , FoxE1 , and FoxI3 in the body skin of cashmere goat fetuses and adult individuals. This study provided new fundamental information for further investigation of the genes related to follicle development and exploration of their roles in hair follicle initiation, growth, and development.

  2. USP7 Attenuates Hepatic Gluconeogenesis Through Modulation of FoxO1 Gene Promoter Occupancy

    Hall, Jessica A.; Tabata, Mitsuhisa; Rodgers, Joseph T.

    2014-01-01

    Hepatic forkhead protein FoxO1 is a key component of systemic glucose homeostasis via its ability to regulate the transcription of rate-limiting enzymes in gluconeogenesis. Important in the regulation of FoxO1 transcriptional activity are the modifying/demodifying enzymes that lead to posttranslational modification. Here, we demonstrate the functional interaction and regulation of FoxO1 by herpesvirus-associated ubiquitin-specific protease 7 (USP7; also known as herpesvirus-associated ubiquitin-specific protease, HAUSP), a deubiquitinating enzyme. We show that USP7-mediated mono-deubiquitination of FoxO1 results in suppression of FoxO1 transcriptional activity through decreased FoxO1 occupancy on the promoters of gluconeogenic genes. Knockdown of USP7 in primary hepatocytes leads to increased expression of FoxO1-target gluconeogenic genes and elevated glucose production. Consistent with this, USP7 gain-of-function suppresses the fasting/cAMP-induced activation of gluconeogenic genes in hepatocyte cells and in mouse liver, resulting in decreased hepatic glucose production. Notably, we show that the effects of USP7 on hepatic glucose metabolism depend on FoxO1. Together, these results place FoxO1 under the intimate regulation of deubiquitination and glucose metabolic control with important implication in diseases such as diabetes. PMID:24694308

  3. [Relationship between FoxO1 Expression and Wound Age during Skin Incised Wound Healing].

    2018-02-01

    To investigate FoxO1 expression and its time-dependent changes during the skin incised wound healing. After the establishment of the skin incised wound model in mice, the FoxO1 expression of skin in different time periods was detected by immunohistochemistry and Western blotting. Immunohistochemistry staining showed that FoxO1 was weakly expressed in a few fibroblasts of epidermis, hair follicles, sebaceous glands, vessel endothelium and dermis in the control group. The FoxO1 expression was enhanced in the epidermis and skin appendages around the wound during 6-12 h after injury, which could be detected in the infiltrating neutrophils and a small number of monocytes. FoxO1 was mainly expressed in monocytes during 1-3 d after injury, and in neovascular endothelial cells and fibroblasts during 5-10 d. On the 14th day after injury, the FoxO1 expression still could be detected in a few fibroblasts. The Western blotting results showed that the FoxO1 expression quantity of the tissue samples in injury group was higher than in control group. The FoxO1 expression peaked at 12 h and 7 d after injury. FoxO1 is time-dependently expressed in skin wound healing, which can be a useful marker for wound age determination.

    2008-01-01

    The forkhead transcription factor FoxA1 is thought to be involved in mammary tumorigenesis. However, the precise role of FoxA1 in breast cancer development is controversial. We examined expression of FoxA1 in 35 human breast cancer cell lines and compared it with that of ErbB2, a marker of poor prognosis in breast cancer. We found that FoxA1 is expressed at high levels in all ErbB2-positive cell lines and a subset of ErbB2-negative cell lines. Down-regulation of FoxA1 by RNA interference significantly suppressed proliferation of ErbB2-negative and FoxA1-positive breast cancer cell lines. Down-regulation of FoxA1 also enhanced the toxic effect of Herceptin on ErbB2-positive cell lines through induction of apoptosis. Taken together with previous data that FoxA1 is a marker of luminal cells in mammary gland, our present results suggest that FoxA1 plays an important role as a lineage-specific oncogene in proliferation of cancer cells derived from mammary luminal cells

  5. Acetylation curtails nucleosome binding, not stable nucleosome remodeling, by FoxO1

    Hatta, M.; Liu, F.; Cirillo, L.A.

    2009-01-01

    Transcriptional activity of FoxO factors is controlled through the actions of multiple growth factors signaling through protein kinase B, whereby phosphorylation of FoxO factors inhibits FoxO-mediated transactivation by promoting nuclear export. Phosphorylation of FoxO factors is enhanced by p300-mediated acetylation, which decreases their affinity for DNA. The negative effect of acetylation on FoxO DNA binding, together with nuclear FoxO mobility, is eliminated by over-expression of the de-acetylase Sirt1, suggesting that acetylation mobilizes FoxO factors in chromatin for inducible gene expression. Here, we show that acetylation significantly curtails the affinity of FoxO1 for its binding sites in nucleosomal DNA but has no effect on either stable nucleosome binding or remodeling by this factor. We suggest that, while acetylation provides a first, essential step toward mobilizing FoxO factors for inducible gene repression, additional mechanisms exist for overcoming their inherent capacity to stably bind and remodel nuclear chromatin.

  6. Turning Science Results into News

    2006-09-01

    Do you want to get into the New York Times? Aside from writing an angry letter or robbing a bank, getting into the news (with your science result) requires a well-crafted press release. Reaching out to reporters is very different from reaching out to fellow scientists. Scientific significance is not the same as newsworthiness, but many science results can be molded into interesting stories that reporters can relate to their audience. This presentation will present examples of science stories that made it big and some that flopped. We will also examine what makes a story attractive to newspaper and magazine editors.

  9. Neuronal IFN-beta-induced PI3K/Akt-FoxA1 signalling is essential for generation of FoxA1(+)Treg cells

    Liu, Yawei; Marin, Andrea; Ejlerskov, Patrick

    2017-01-01

    Neurons reprogramme encephalitogenic T cells (Tenc) to regulatory T cells (Tregs), either FoxP3(+)Tregs or FoxA1(+)Tregs. We reported previously that neuronal ability to generate FoxA1(+)Tregs was central to preventing neuroinflammation in experimental autoimmune encephalomyelitis (EAE). Mice...... lacking interferon (IFN)-β were defective in generating FoxA1(+)Tregs in the brain. Here we show that lack of neuronal IFNβ signalling is associated with the absence of programme death ligand-1 (PDL1), which prevents their ability to reprogramme Tenc cells to FoxA1(+)Tregs. Passive transfer-EAE via IFNβ......-competent Tenc cells to mice lacking IFNβ and active induced-EAE in mice lacking its receptor, IFNAR, in the brain (Nes(Cre):Ifnar(fl/fl)) result in defective FoxA1(+)Tregs generation and aggravated neuroinflammation. IFNβ activates neuronal PI3K/Akt signalling and Akt binds to transcription factor FoxA1...

  10. Sequence comparison of prefrontal cortical brain transcriptome from a tame and an aggressive silver fox (Vulpes vulpes)

    2011-01-01

    Background Two strains of the silver fox (Vulpes vulpes), with markedly different behavioral phenotypes, have been developed by long-term selection for behavior. Foxes from the tame strain exhibit friendly behavior towards humans, paralleling the sociability of canine puppies, whereas foxes from the aggressive strain are defensive and exhibit aggression to humans. To understand the genetic differences underlying these behavioral phenotypes fox-specific genomic resources are needed. Results cDNA from mRNA from pre-frontal cortex of a tame and an aggressive fox was sequenced using the Roche 454 FLX Titanium platform (> 2.5 million reads & 0.9 Gbase of tame fox sequence; >3.3 million reads & 1.2 Gbase of aggressive fox sequence). Over 80% of the fox reads were assembled into contigs. Mapping fox reads against the fox transcriptome assembly and the dog genome identified over 30,000 high confidence fox-specific SNPs. Fox transcripts for approximately 14,000 genes were identified using SwissProt and the dog RefSeq databases. An at least 2-fold expression difference between the two samples (p fox transcriptome. Conclusions Transcriptome sequencing significantly expanded genomic resources available for the fox, a species without a sequenced genome. In a very cost efficient manner this yielded a large number of fox-specific SNP markers for genetic studies and provided significant insights into the gene expression profile of the fox pre-frontal cortex; expression differences between the two fox samples; and a catalogue of potentially important gene-specific sequence variants. This result demonstrates the utility of this approach for developing genomic resources in species with limited genomic information. PMID:21967120

  11. Going Down the Hole: Beaconsfield, Celebrities and the Changing News Culture in Australia

    Jason Bainbridge

    2011-04-01

    Full Text Available For fourteen days, all of Australia and much of the world was focused on the rescue of two miners trapped underground in Beaconsfield, Tasmania. This article looks at the period from Todd Russell and Brant Webb’s rescue up to and including Channel Nine’s screening of an exclusive interview with the men on 21 May 2006. It analyses the ways in which Beaconsfield was reported—and the exclusive interview with the miners pursued—as a way of exploring notions of celebrity, infotainment, chequebook journalism and the changing shape of news culture in Australia. For these reasons, the events at Beaconsfield should not be dismissed as just another news story, but rather, should be regarded as indicative of the ways in which news is increasingly being reported, packaged and folded back into larger entertainment structures.

  12. Specific detection of Echinococcus spp. from the Tibetan fox (Vulpes ferrilata) and the red fox (V. vulpes) using copro-DNA PCR analysis.

    2012-10-01

    There are three Echinococcus species, Echinococcus granulosus, E. multilocularis, and E. shiquicus, which are distributed on the vast area of pastureland on the eastern Tibetan plateau in China. Tibetan foxes (Vulpes ferrilata) have been determined to be the main wild definitive host of E. multilocularis and E. shiquicus, but little information is available on the prevalence of these two parasites in Tibetan foxes. Consequently, the copro-prevalence of these parasites in foxes from the eastern Tibetan plateau was evaluated in this study. For each copro-DNA sample extracted from fox feces, a 133-bp segment of EgG1 Hae III was used to screen for infection with E. granulosus. Multiplex nested polymerase chain reaction (PCR) analysis was used to target an 874-bp segment of the mitochondrial COI gene to distinguish E. multilocularis and E. shiquicus. Among 184 fecal samples, 120 were from Tibetan foxes and six from red foxes (Vulpes vulpes). Of the fecal samples from Tibetan foxes, 74 (giving a copro-prevalence of 62%) showed the presence of Echinococcus spp.: 23 (19%) were found to contain E. multilocularis, 32 (27%) E. shiquicus, and 19 (16%) showed mixed infection with both E. multilocularis and E. shiquicus. Two fecal samples from red foxes were found to be infected with E. multilocularis. No fox feces were found to be infected with E. granulosus. Tests on zinc finger protein genes and a 105-bp fragment of the Sry gene found no significant difference in the prevalence of the two parasites between sexes. The efficiency of our multiplex nested PCR methods were compared with previous polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) methods and some problems associated with the copro-PCR were discussed.

  13. Press problem related to nuclear energy news reporting

    2008-01-01

    Since the event of Niigataken Chuetsu-oki Earthquake in 2007 and the subsequent press reports on damage of nuclear power station after it, a stance of media is being questioned. In order to clear this problem, basic organizational structure of the press related to nuclear energy news was analyzed. Local news department, social news department, science news department and economical news department involve in nuclear energy news the accordance with their own situations and concerns. This structure makes problem of nuclear energy news reporting complicated. Changing this system is required but very difficult. It is concluded that the press problem around nuclear energy news is strange. (author)

    2018-01-01

    Even democracies endowed with the most active free press struggle to maintain diversity of news coverage. Consolidation and market forces may cause only a few dominant players to control the news cycle. Editorial policies may be biased by corporate ownership relations, narrowing news coverage and focus. To an increasing degree this problem also applies to social media news distribution, since it is subject to the same socio-economic drivers. To study the effects of consolidation and ownership on news diversity, we model the diversity of Chilean coverage on the basis of ownership records and social media data. We create similarity networks of news outlets on the basis of their ownership and the topics they cover. We then examine the relationships between the topology of ownership networks and content similarity to characterize how ownership affects news coverage. A network analysis reveals that Chilean media is highly concentrated both in terms of ownership as well as in terms of topics covered. Our method can be used to determine which groups of outlets and ownership exert the greatest influence on news coverage.

    Richard Gilbech, External Tank "Tiger Team" Lead, begins this space shuttle news conference with detailing the two major objectives of the team. The objectives include: 1) Finding the root cause of the foam loss on STS-114; and 2) Near and long term improvements for the external tank. Wayne Hale, Space Shuttle Program Manager, presents a chart to explain the external tank foam loss during STS-114. He gives a possible launch date for STS-121 after there has been a repair to the foam on the External Tank. He further discusses the changes that need to be made to the surrounding areas of the plant in New Orleans, due to Hurricane Katrina. Bill Gerstemaier, NASA Associate Administrator for Space Operations, elaborates on the testing of the external tank foam loss. The discussion ends with questions from the news media about a fix for the foam, replacement of the tiles, foam loss avoidance, the root cause of foam loss and a possible date for a new external tank to be shipped to NASA Kennedy Space Center.

    2012-12-01

    NASA's Energy and Water Cycle Study (NEWS) program fosters collaborative research towards improved quantification and prediction of water and energy cycle consequences of climate change. In order to measure change, it is first necessary to describe current conditions. The goal of the first phase of the NEWS Water and Energy Cycle Climatology project was to develop "state of the global water cycle" and "state of the global energy cycle" assessments based on data from modern ground and space based observing systems and data integrating models. The project was a multi-institutional collaboration with more than 20 active contributors. This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

This presentation will describe the results of the water cycle component of the first phase of the project, which include seasonal (monthly) climatologies of water fluxes over land, ocean, and atmosphere at continental and ocean basin scales. The requirement of closure of the water budget (i.e., mass conservation) at various scales was exploited to constrain the flux estimates via an optimization approach that will also be described. Further, error assessments were included with the input datasets, and we examine these in relation to inferred uncertainty in the optimized flux estimates in order to gauge our current ability to close the water budget within an expected uncertainty range.

  7. News from Council - September 2016

    2016-01-01

    I would like to inform you of the main news from the Council this week. First of all, the Council congratulated CERN and the Collaborations on the superb performance of the accelerator complex and experiments. It has been a great year so far, with important physics results across the whole spectrum of the CERN research programme.   Looking forward, one of the main accomplishments from this week’s meetings is that the Council has approved the opening of a credit facility with the European Investment Bank (EIB) to cover the cash shortage during the peak years of the High-Luminosity LHC (HL-LHC) construction. This is very good news since it will allow us to carry out the work necessary for the HL-LHC without compromising the rest of the Laboratory’s scientific programme. Turning to the scientific and geographical enlargement, the Council approved the admission of India as an Associate Member State, and I very much hope that the agreement can be signed in the near future so that Indi...

  16. Data Exchanges in Mobile News Apps

    Kammer, Aske; Wallberg, Filip

    This paper maps the flows of data to and from third-party actors when users access content in mobile news apps. This way, it analyzes the strategic networks of collaboration and data exchange that news organizations engage in in the digital economy, expanding the traditional two-sided model...... of media economics (centered around sales to audiences and advertisers) to also account for what happens “behind the curtain”. Research already shows that the trade with data constitutes a central component of web-based business models (Evens & Van Damme, 2016; Gerlitz & Helmond, 2013; Lindskow, 2016......), but no systematic scrutiny of the same phenomenon exists with regards to mobile news use even though the use of mobile platforms for news accessing increases these years (Newman, Levy, & Nielsen, 2015).

  17. Adaptive divergence despite strong genetic drift: genomic analysis of the evolutionary mechanisms causing genetic differentiation in the island fox (Urocyon littoralis)

    The evolutionary mechanisms generating the tremendous biodiversity of islands have long fascinated evolutionary biologists. Genetic drift and divergent selection are predicted to be strong on islands and both could drive population divergence and speciation. Alternatively, strong genetic drift may preclude adaptation. We conducted a genomic analysis to test the roles of genetic drift and divergent selection in causing genetic differentiation among populations of the island fox (Urocyon littoralis). This species consists of 6 subspecies, each of which occupies a different California Channel Island. Analysis of 5293 SNP loci generated using Restriction-site Associated DNA (RAD) sequencing found support for genetic drift as the dominant evolutionary mechanism driving population divergence among island fox populations. In particular, populations had exceptionally low genetic variation, small Ne (range = 2.1–89.7; median = 19.4), and significant genetic signatures of bottlenecks. Moreover, islands with the lowest genetic variation (and, by inference, the strongest historical genetic drift) were most genetically differentiated from mainland gray foxes, and vice versa, indicating genetic drift drives genome-wide divergence. Nonetheless, outlier tests identified 3.6–6.6% of loci as high FST outliers, suggesting that despite strong genetic drift, divergent selection contributes to population divergence. Patterns of similarity among populations based on high FST outliers mirrored patterns based on morphology, providing additional evidence that outliers reflect adaptive divergence. Extremely low genetic variation and small Ne in some island fox populations, particularly on San Nicolas Island, suggest that they may be vulnerable to fixation of deleterious alleles, decreased fitness, and reduced adaptive potential.

  19. Sequence comparison of prefrontal cortical brain transcriptome from a tame and an aggressive silver fox (Vulpes vulpes

    Sun Qi

    2011-10-01

    Full Text Available Abstract Background Two strains of the silver fox (Vulpes vulpes, with markedly different behavioral phenotypes, have been developed by long-term selection for behavior. Foxes from the tame strain exhibit friendly behavior towards humans, paralleling the sociability of canine puppies, whereas foxes from the aggressive strain are defensive and exhibit aggression to humans. To understand the genetic differences underlying these behavioral phenotypes fox-specific genomic resources are needed. Results cDNA from mRNA from pre-frontal cortex of a tame and an aggressive fox was sequenced using the Roche 454 FLX Titanium platform (> 2.5 million reads & 0.9 Gbase of tame fox sequence; >3.3 million reads & 1.2 Gbase of aggressive fox sequence. Over 80% of the fox reads were assembled into contigs. Mapping fox reads against the fox transcriptome assembly and the dog genome identified over 30,000 high confidence fox-specific SNPs. Fox transcripts for approximately 14,000 genes were identified using SwissProt and the dog RefSeq databases. An at least 2-fold expression difference between the two samples (p Conclusions Transcriptome sequencing significantly expanded genomic resources available for the fox, a species without a sequenced genome. In a very cost efficient manner this yielded a large number of fox-specific SNP markers for genetic studies and provided significant insights into the gene expression profile of the fox pre-frontal cortex; expression differences between the two fox samples; and a catalogue of potentially important gene-specific sequence variants. This result demonstrates the utility of this approach for developing genomic resources in species with limited genomic information.

  2. FoxO and stress responses in the cnidarian Hydra vulgaris.

    Diane Bridge

    2010-07-01

    Full Text Available In the face of changing environmental conditions, the mechanisms underlying stress responses in diverse organisms are of increasing interest. In vertebrates, Drosophila, and Caenorhabditis elegans, FoxO transcription factors mediate cellular responses to stress, including oxidative stress and dietary restriction. Although FoxO genes have been identified in early-arising animal lineages including sponges and cnidarians, little is known about their roles in these organisms.We have examined the regulation of FoxO activity in members of the well-studied cnidarian genus Hydra. We find that Hydra FoxO is expressed at high levels in cells of the interstitial lineage, a cell lineage that includes multipotent stem cells that give rise to neurons, stinging cells, secretory cells and gametes. Using transgenic Hydra that express a FoxO-GFP fusion protein in cells of the interstitial lineage, we have determined that heat shock causes localization of the fusion protein to the nucleus. Our results also provide evidence that, as in bilaterian animals, Hydra FoxO activity is regulated by both Akt and JNK kinases.These findings imply that basic mechanisms of FoxO regulation arose before the evolution of bilaterians and raise the possibility that FoxO is involved in stress responses of other cnidarian species, including corals.

  3. Complete Mitochondrial Genome of the Red Fox (Vuples vuples) and Phylogenetic Analysis with Other Canid Species.

    Zhong, Hua-Ming; Zhang, Hong-Hai; Sha, Wei-Lai; Zhang, Cheng-De; Chen, Yu-Cai

    2010-04-01

    The whole mitochondrial genome sequence of red fox (Vuples vuples) was determined. It had a total length of 16 723 bp. As in most mammal mitochondrial genome, it contained 13 protein coding genes, two ribosome RNA genes, 22 transfer RNA genes and one control region. The base composition was 31.3% A, 26.1% C, 14.8% G and 27.8% T, respectively. The codon usage of red fox, arctic fox, gray wolf, domestic dog and coyote followed the same pattern except for an unusual ATT start codon, which initiates the NADH dehydrogenase subunit 3 gene in the red fox. A long tandem repeat rich in AC was found between conserved sequence block 1 and 2 in the control region. In order to confirm the phylogenetic relationships of red fox to other canids, phylogenetic trees were reconstructed by neighbor-joining and maximum parsimony methods using 12 concatenated heavy-strand protein-coding genes. The result indicated that arctic fox was the sister group of red fox and they both belong to the red fox-like clade in family Canidae, while gray wolf, domestic dog and coyote belong to wolf-like clade. The result was in accordance with existing phylogenetic results.

  9. Physiological adaptations to fasting in an actively wintering canid, the Arctic blue fox (Alopex lagopus).

    Mustonen, Anne-Mari; Pyykönen, Teija; Puukka, Matti; Asikainen, Juha; Hänninen, Sari; Mononen, Jaakko; Nieminen, Petteri

    2006-01-01

    This study investigated the physiological adaptations to fasting using the farmed blue fox (Alopex lagopus) as a model for the endangered wild arctic fox. Sixteen blue foxes were fed throughout the winter and 32 blue foxes were fasted for 22 d in Nov-Dec 2002. Half of the fasted blue foxes were food-deprived again for 22 d in Jan-Feb 2003. The farmed blue fox lost weight at a slower rate (0.97-1.02% body mass d(-1)) than observed previously in the arctic fox, possibly due to its higher initial body fat content. The animals experienced occasional fasting-induced hypoglycaemia, but their locomotor activity was not affected. The plasma triacylglycerol and glycerol concentrations were elevated during phase II of fasting indicating stimulated lipolysis, probably induced by the high growth hormone concentrations. The total cholesterol, HDL- and LDL-cholesterol, urea, uric acid and total protein levels and the urea:creatinine ratio decreased during fasting. Although the plasma levels of some essential amino acids increased, the blue foxes did not enter phase III of starvation characterized by stimulated proteolysis during either of the 22-d fasting procedures. Instead of excessive protein catabolism, it is liver dysfunction, indicated by the increased plasma bilirubin levels and alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase activities, that may limit the duration of fasting in the species.

  13. FoxO1 in dopaminergic neurons regulates energy homeostasis and targets tyrosine hydroxylase

    2016-01-01

    Dopaminergic (DA) neurons are involved in the integration of neuronal and hormonal signals to regulate food consumption and energy balance. Forkhead transcriptional factor O1 (FoxO1) in the hypothalamus plays a crucial role in mediation of leptin and insulin function. However, the homoeostatic role of FoxO1 in DA system has not been investigated. Here we report that FoxO1 is highly expressed in DA neurons and mice lacking FoxO1 specifically in the DA neurons (FoxO1 KODAT) show markedly increased energy expenditure and interscapular brown adipose tissue (iBAT) thermogenesis accompanied by reduced fat mass and improved glucose/insulin homoeostasis. Moreover, FoxO1 KODAT mice exhibit an increased sucrose preference in concomitance with higher dopamine and norepinephrine levels. Finally, we found that FoxO1 directly targets and negatively regulates tyrosine hydroxylase (TH) expression, the rate-limiting enzyme of the catecholamine synthesis, delineating a mechanism for the KO phenotypes. Collectively, these results suggest that FoxO1 in DA neurons is an important transcriptional factor that directs the coordinated control of energy balance, thermogenesis and glucose homoeostasis.

  16. Probing the Mechanism of Inactivation of the FOX-4 Cephamycinase by Avibactam.

    Nukaga, Michiyoshi; Papp-Wallace, Krisztina M; Hoshino, Tyuji; Lefurgy, Scott T; Bethel, Christopher R; Barnes, Melissa D; Zeiser, Elise T; Johnson, J Kristie; Bonomo, Robert A

    2018-05-01

    Ceftazidime-avibactam is a "second-generation" β-lactam-β-lactamase inhibitor combination that is effective against Enterobacteriaceae expressing class A extended-spectrum β-lactamases, class A carbapenemases, and/or class C cephalosporinases. Knowledge of the interactions of avibactam, a diazabicyclooctane with different β-lactamases, is required to anticipate future resistance threats. FOX family β-lactamases possess unique hydrolytic properties with a broadened substrate profile to include cephamycins, partly as a result of an isoleucine at position 346, instead of the conserved asparagine found in most AmpCs. Interestingly, a single amino acid substitution at N346 in the Citrobacter AmpC is implicated in resistance to the aztreonam-avibactam combination. In order to understand how diverse active-site topologies affect avibactam inhibition, we tested a panel of clinical Enterobacteriaceae isolates producing bla FOX using ceftazidime-avibactam, determined the biochemical parameters for inhibition using the FOX-4 variant, and probed the atomic structure of avibactam with FOX-4. Avibactam restored susceptibility to ceftazidime for most isolates producing bla FOX ; two isolates, one expressing bla FOX-4 and the other producing bla FOX-5 , displayed an MIC of 16 μg/ml for the combination. FOX-4 possessed a k 2 / K value of 1,800 ± 100 M -1 · s -1 and an off rate ( k off ) of 0.0013 ± 0.0003 s -1 Mass spectrometry showed that the FOX-4-avibactam complex did not undergo chemical modification for 24 h. Analysis of the crystal structure of FOX-4 with avibactam at a 1.5-Å resolution revealed a unique characteristic of this AmpC β-lactamase. Unlike in the Pseudomonas -derived cephalosporinase 1 (PDC-1)-avibactam crystal structure, interactions (e.g., hydrogen bonding) between avibactam and position I346 in FOX-4 are not evident. Furthermore, another residue is not observed to be close enough to compensate for the loss of these critical hydrogen

  17. Trypanosomiasis in an Australian little red flying fox (Pteropus scapulatus).

    Mackie, J T; Stenner, R; Gillett, A K; Barbosa, A; Ryan, U; Irwin, P J

    2017-07-01

    An adult female Australian little red flying fox (Pteropus scapulatus) presented with icterus and anaemia. Examination of a blood smear revealed numerous trypanosomes 20.4-30.8 µm long with tapered ends. Necropsy and histological findings were consistent with trypanosome infection of lymphoid tissue and intravascular haemolysis. Sequence and phylogenetic analysis demonstrated this trypanosome species to be genetically distinct and most similar to Trypanosoma minasense and Trypanosoma rangeli (with a genetic distance of 1% at the 18S rRNA locus for both). To the authors' knowledge this is the first report of a trypanosome infection associated with clinical disease in bats. © 2017 Australian Veterinary Association.

    2014-12-01

    A 10-mo-old female fennec fox (Vulpes zerda) with drooling suddenly died and was examined postmortem. Histologic examination of different tissue samples was performed. Vacuolar degeneration and diffuse fatty change were observed in the liver. Several diagnostic methods were used to screen for canine parvovirus, canine distemper virus, canine influenza virus, canine coronavirus, canine parainfluenza virus, and canine adenovirus (CAdV). Only CAdV type 1 (CAdV-1) was detected in several organs (liver, lung, brain, kidney, spleen, and heart), and other viruses were not found. CAdV-1 was confirmed by virus isolation and nucleotide sequencing.

    2014-04-03

    The red fox (Vulpes vulpes) is host to a community of zoonotic and other helminth species. Tracking their community structure and dynamics over decades is one way to monitor the long term risk of parasitic infectious diseases relevant to public and veterinary health. We identified 17 helminth species from 136 foxes by mucosal scraping, centrifugal sedimentation/flotation and the washing and sieving technique. We applied rarefaction analysis to our samples and compared the resulting curve to the helminth community reported in literature 35 years ago. Fox helminth species significantly increased in number in the last 35 years (p-value <0.025). Toxascaris leonina, Mesocestoides litteratus, Trichuris vulpis and Angiostrongylus vasorum are four new veterinary-relevant species. The zoonotic fox tapeworm (E. multilocularis) was found outside the previously described endemic regions in the Netherlands. Helminth fauna in Dutch red foxes increased in biodiversity over the last three decades.

  20. Breaking bad news in cancer patients.

    Konstantis, Apostolos; Exiara, Triada

    2015-01-01

    In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59%) had specific training on breaking bad news. 20 doctors (33.90%) were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66%) had a consistent plan for breaking bad news. 57 (96.61%) delivered bad news in a quiet place, 53 (89.83%) ensured no interruptions and enough time, 53 (89.83%) used simple words and 54 (91.53%) checked for understanding and did not rush through the news. 46 doctors (77.97%) allowed relatives to determine patient's knowledge about the disease. There were low rates of specific training in breaking bad news. However, the selected location, the physician's speech and their plan were according to current guidelines.

Materials and Methods: 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Results: Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59% had specific training on breaking bad news. 20 doctors (33.90% were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66% had a consistent plan for breaking bad news. 57 (96.61% delivered bad news in a quiet place, 53 (89.83% ensured no interruptions and enough time, 53 (89.83% used simple words and 54 (91.53% checked for understanding and did not rush through the news. 46 doctors (77.97% allowed relatives to determine patient′s knowledge about the disease. Conclusions: There were low rates of specific training in breaking bad news. However, the selected location, the physician′s speech and their plan were according to current guidelines.

  2. The news machine hacking, the untold story

    Hanning, James

    2014-01-01

    There is one mystery figure at the heart of ?Hackergate' ? Glenn Mulcaire, the News of the World's top private investigator. The former AFC Wimbledon footballer has never spoken publicly or in court about his work investigating and backing up front-page news stories (such as the News of the World's award-winning David Beckham scoop). Mulcaire's arrest in 2006 for intercepting royal-household phone messages barely registered at the time. Yet his work has continued to generate headlines and embarrassment for the establishment ? with a Prime Minister on the back foot after his former aide Andy

    Wild animals, especially canids, are important reservoirs of vector-borne pathogens, that are transmitted by the ticks and other bloodsucking arthropods. In total, 300 red foxes (Vulpes vulpes), shot by the hunters in eastern and northern Slovakia, were screened for the presence of vector-borne pathogens by PCR-based methods Blood samples were obtained from nine red foxes and tissue samples originated from 291 animals (the liver tissue samples from 49 foxes and spleen samples from 242 red foxes). Babesia vulpes and haemotropic Mycoplasma species were identified by amplification and sequencing of 18S rRNA and 16S rRNA gene fragments, respectively. Overall, the presence of these pathogens was recorded in 12.3% of screened DNA samples. Altogether 9.7% (29/300) of investigated foxes carried DNA of Babesia spp. In total, 12 out of 29 Babesia spp. PCR - positive amplicons were further sequenced and identified as B. vulpes (41.4%; 12/29), remaining 17 samples are referred as Babesia sp. (58.6%; 17/29). Overall prevalence of B. vulpes reached 4.0% (n=300). Thirteen (4.3%) samples tested positive for distinct Mycoplasma species. To the best of our knowledge, this study brings the first information on B. vulpes infection in red foxes in Slovakia, and the first data on the prevalence and diversity of haemotropic Mycoplasma spp. in European red fox population. Moreover, co-infections with B. vulpes and Mycoplasma spp. were confirmed in 1.7% of tested DNA samples. The relatively high rates of blood pathogen' prevalence and species diversity in wild foxes indicate the role of the fox population in the maintenance of the parasites in sylvatic cycles and strengthen the assumption that foxes play an important role in spreading of infectious microorganisms within and outside the natural foci.

    High-quality sequencing of the dog (Canis lupus familiaris) genome has enabled enormous progress in genetic mapping of canine phenotypic variation. The red fox (Vulpes vulpes), another canid species, also exhibits a wide range of variation in coat color, morphology, and behavior. Although the fox genome has not yet been sequenced, canine genomic resources have been used to construct a meiotic linkage map of the red fox genome and begin genetic mapping in foxes. However, a more detailed gene-specific comparative map between the dog and fox genomes is required to establish gene order within homologous regions of dog and fox chromosomes and to refine breakpoints between homologous chromosomes of the 2 species. In the current study, we tested whether canine-derived gene-containing bacterial artificial chromosome (BAC) clones can be routinely used to build a gene-specific map of the red fox genome. Forty canine BAC clones were mapped to the red fox genome by fluorescence in situ hybridization (FISH). Each clone was uniquely assigned to a single fox chromosome, and the locations of 38 clones agreed with cytogenetic predictions. These results clearly demonstrate the utility of FISH mapping for construction of a whole-genome gene-specific map of the red fox. The further possibility of using canine BAC clones to map genes in the American mink (Mustela vison) genome was also explored. Much lower success was obtained for this more distantly related farm-bred species, although a few BAC clones were mapped to the predicted chromosomal locations.

  6. SCP4 Promotes Gluconeogenesis Through FoxO1/3a Dephosphorylation.

    2018-01-01

    FoxO1 and FoxO3a (collectively FoxO1/3a) proteins regulate a wide array of cellular processes, including hepatic gluconeogenesis. Phosphorylation of FoxO1/3a is a key event that determines its subcellular location and transcriptional activity. During glucose synthesis, the activity of FoxO1/3a is negatively regulated by Akt-mediated phosphorylation, which leads to the cytoplasmic retention of FoxO1/3a. However, the nuclear phosphatase that directly regulates FoxO1/3a remains to be identified. In this study, we discovered a nuclear phosphatase, SCP4/CTDSPL2 (SCP4), that dephosphorylated FoxO1/3a and promoted FoxO1/3a transcription activity. We found that SCP4 enhanced the transcription of FoxO1/3a target genes encoding PEPCK1 and G6PC, key enzymes in hepatic gluconeogenesis. Ectopic expression of SCP4 increased, while knockdown of SCP4 inhibited, glucose production. Moreover, we demonstrated that gene ablation of SCP4 led to hypoglycemia in neonatal mice. Consistent with the positive role of SCP4 in gluconeogenesis, expression of SCP4 was regulated under pathophysiological conditions. SCP4 expression was induced by glucose deprivation in vitro and in vivo and was elevated in obese mice caused by genetic (A vy ) and dietary (high-fat) changes. Thus, our findings provided experimental evidence that SCP4 regulates hepatic gluconeogenesis and could serve as a potential target for the prevention and treatment of diet-induced glucose intolerance and type 2 diabetes. © 2017 by the American Diabetes Association.

  11. Healthy depictions? Depicting adoption and adoption news events on broadcast news.

    Kline, Susan L; Chatterjee, Karishma; Karel, Amanda I

    2009-01-01

    Given that the public uses the media to learn about adoption as a family form, this study analyzes U.S. television news coverage of adoption between 2001 and 2005 (N = 309 stories), to identify the types of news events covered about adoption. A majority of news stories covered fraud, crime, legal disputes, and negative international adoption cases. Adoptees as defective or unhealthy were depicted more in negative news event stories, birth parents appeared less overall, and adoptive parents were most likely to have healthy depictions in positively oriented adoption experience, big family, and reunion stories. Although three quarters of the stories used primary adoption participants as news sources, one-third of the negative event stories did not contain healthy depictions of adoption participants. The authors discuss ways journalists and researchers might improve adoption news coverage.

Experiments show that the method of story segmentation is effective and the retrieval is also efficient.

  14. The U.S. Online News Coverage of Mammography Based on a Google News Search.

    Young Lin, Leng Leng; Rosenkrantz, Andrew B

    2017-12-01

    To characterize online news coverage relating to mammography, including articles' stance toward screening mammography. Google News was used to search U.S. news sites over a 9-year period (2006-2015) based on the search terms "mammography" and "mammogram." The top 100 search results were recorded. Identified articles were manually reviewed. The top 100 news articles were from the following sources: local news outlet (50%), national news outlet (24%), nonimaging medical source (13%), entertainment or culture news outlet (6%), business news outlet (4%), peer-reviewed journal (1%), and radiology news outlet (1%). Most common major themes were the screening mammography controversy (29%), description of a new breast imaging technology (23%), dense breasts (11%), and promotion of a public screening initiative (11%). For the most recent year, article stance toward screening mammography was 59%, favorable; 16%, unfavorable; and 25%, neutral. After 2010, there was an abrupt shift in articles' stances from neutral to both favorable and unfavorable. A wide range of online news sources addressed a range of issues related to mammography. National, rather than local, news sites were more likely to focus on the screening controversy and more likely to take an unfavorable view. The controversial United States Preventive Services Task Force guidelines may have influenced articles to take a stance on screening mammography. As such online news may impact public perception of the topic and thus potentially impact guideline adherence, radiologists are encouraged to maintain awareness of this online coverage and to support the online dissemination of reliable and accurate information.

  16. Incorporating popularity in a personalized news recommender system

    Nirmal Jonnalagedda

    2016-06-01

    Full Text Available Online news reading has become a widely popular way to read news articles from news sources around the globe. With the enormous amount of news articles available, users are easily overwhelmed by information of little interest to them. News recommender systems help users manage this flood by recommending articles based on user interests rather than presenting articles in order of their occurrence. We present our research on developing personalized news recommendation system with the help of a popular micro-blogging service, “Twitter.” News articles are ranked based on the popularity of the article identified from Twitter’s public timeline. In addition, users construct profiles based on their interests and news articles are also ranked based on their match to the user profile. By integrating these two approaches, we present a hybrid news recommendation model that recommends interesting news articles to the user based on their popularity as well as their relevance to the user profile.

    2013-12-01

    In the present study, 428 foxes were collected and examined for intestinal helminths using the washing-out method. Parasites were found in 93.2% of the examined animals. The most frequently identified nematodes were Uncinaria stenocephala (58.9%), Toxocara canis (38.3%) and Molineus patens (30.6%). Other nematodes found were Pterygodermatites affinis (4.2%), Capillaria sp. (2.8%), Crenosoma vulpis (2.8%), Toxascaris leonina (2.5%), Trichuris vulpis (0.7%) and Physaloptera sp. (0.2%). Mesocestoides sp. (27.6%) and Taenia crassiceps (22.2%) were the most prevalent cestodes, followed by T. polyacantha (6.5%), Hymenolepis nana (2.1%), T. pisiformis (2.1%) and Dipylidium caninum (1.4%). The study also revealed four trematode species: Rossicotrema donicum (1.6%), Heterophyes heterophyes (1.1%), Metagonimus yokogawai (1.1%), Prohemistomum appendiculatum (0.4%) and two protozoan species: oocysts of Sarcocystis (2.8%) and Isospora (0.4%). This is the first extensive study on the intestinal parasites of the red fox (Vulpes vulpes) in Slovenia. The 2.6% prevalence of Echinococcus multilocularis in the same sample population as investigated herein has been reported previously (Vergles Rataj et al., 2010).

  18. Risk aversion affects economic values of blue fox breeding scheme.

    2016-12-01

    The profit and production of an average Finnish blue fox farm was simulated using a deterministic bio-economic farm model. Risk was included using Arrow-Prat absolute risk aversion coefficient and profit variance. Risk-rated economic values were calculated for pregnancy rate, litter loss, litter size, pelt size, pelt quality, pelt colour clarity, feed efficiency and eye infection. With high absolute risk aversion, economic values were lower than with low absolute risk aversion. Economic values were highest for litter loss (18.16 and 26.42 EUR), litter size (13.27 and 19.40 EUR), pregnancy (11.99 and 18.39 EUR) and eye infection (12.39 and 13.81 EUR). Sensitivity analysis showed that selection pressure for improved eye health depended strongly on proportion of culled animals among infected animals and much less on the proportion of infected animals. The economic value of feed efficiency was lower than expected (6.06 and 8.03 EUR). However, it was almost the same magnitude as pelt quality (7.30 and 7.30 EUR) and higher than the economic value of pelt size (3.37 and 5.26 EUR). Risk factors should be considered in blue fox breeding scheme because they change the relative importance of traits. © 2016 Blackwell Verlag GmbH.

  1. Does iris(in) bring bad news or good news?

    Buscemi, Silvio; Corleo, Davide; Buscemi, Carola; Giordano, Carla

    2017-09-20

    Irisin, a novel myokine produced in response to physical activity, promotes white-to-brown fat transdifferentiation. The name irisin referred to the ancient Greek goddess Iris, the messenger who delivered (bad) news from the gods. In mice, it has been demonstrated that irisin plays a key role in metabolic regulation, energy expenditure and glucose homeostasis. New findings from various studies carried out in both animals and humans suggest that irisin might also have other favorable effects, such as increasing bone cortical mass, preventing hepatic lipid accumulation, and improving cognitive functions, thus mediating many exercise-induced health benefits. However, data on the role and function of irisin in humans have prompted controversy, due mostly to the only recent confirmation of the presence of irisin in humans. Another strong limitation to the understanding of irisin mechanisms of action is the lack of knowledge about its receptor, which until now remains unidentified in humans and in animals. This review presents an overall analysis of the history of irisin, its expression, and its involvement in health, especially in humans. Level of Evidence Level V, review.

    This paper proposes a new method to compute the news impact curve for stochastic volatility (SV) models. The new method incorporates the joint movement of return and volatility, which has been ignored by the extant literature, by simply adding a couple of steps to the Bayesian MCMC estimation procedures for SV models. This simple procedure is versatile and applicable to various SV type models. Contrary to the monotonic news impact functions in the extant literature, the new method gives a U-s...

  9. 'BREAKS' Protocol for Breaking Bad News.

    Narayanan, Vijayakumar; Bista, Bibek; Koshy, Cheriyan

    2010-05-01

    Information that drastically alters the life world of the patient is termed as bad news. Conveying bad news is a skilled communication, and not at all easy. The amount of truth to be disclosed is subjective. A properly structured and well-orchestrated communication has a positive therapeutic effect. This is a process of negotiation between patient and physician, but physicians often find it difficult due to many reasons. They feel incompetent and are afraid of unleashing a negative reaction from the patient or their relatives. The physician is reminded of his or her own vulnerability to terminal illness, and find themselves powerless over emotional distress. Lack of sufficient training in breaking bad news is a handicap to most physicians and health care workers. Adherence to the principles of client-centered counseling is helpful in attaining this skill. Fundamental insight of the patient is exploited and the bad news is delivered in a structured manner, because the patient is the one who knows what is hurting him most and he is the one who knows how to move forward. Six-step SPIKES protocol is widely used for breaking bad news. In this paper, we put forward another six-step protocol, the BREAKS protocol as a systematic and easy communication strategy for breaking bad news. Development of competence in dealing with difficult situations has positive therapeutic outcome and is a professionally satisfying one.

  10. Inhibition of FoxO1 acetylation by INHAT subunit SET/TAF-Iβ induces p21 transcription.

    Chae, Yun-Cheol; Kim, Kee-Beom; Kang, Joo-Young; Kim, Se-Ryeon; Jung, Hyeon-Soo; Seo, Sang-Beom

    2014-08-25

    Post-translational modification of forkhead family transcription factor, FoxO1, is an important regulatory mode for its diverse activities. FoxO1 is acetylated by HAT coactivators and its transcriptional activity is decreased via reduced DNA binding affinity. Here, we report that SET/TAF-Iβ inhibited p300-mediated FoxO1 acetylation in an INHAT domain-dependent manner. SET/TAF-Iβ interacted with FoxO1 and activated transcription of FoxO1 target gene, p21. Moreover, SET/TAF-Iβ inhibited acetylation of FoxO1 and increased p21 transcription induced by oxidative stress. Our results suggest that SET/TAF-Iβ inhibits FoxO1 acetylation and activates its transcriptional activity toward p21. Copyright © 2014 Federation of European Biochemical Societies.

  12. Ion channeling

    Erramli, H.; Blondiaux, G.

    1994-01-01

    Channeling phenomenon was predicted, many years ago, by stark. The first channeling experiments were performed in 1963 by Davies and his coworkers. Parallely Robinson and Oen have investigated this process by simulating trajectories of ions in monocrystals. This technique has been combined with many methods like Rutherford Backscattering Spectrometry (R.B.S.), Particles Induced X-rays Emission (P.I.X.E) and online Nuclear Reaction (N.R.A.) to localize trace elements in the crystal or to determine crystalline quality. To use channeling for material characterization we need data about the stopping power of the incident particle in the channeled direction. The ratios of channeled to random stopping powers of silicon for irradiation in the direction have been investigated and compared to the available theoretical results. We describe few applications of ion channeling in the field of materials characterization. Special attention is given to ion channeling combined with Charged Particle Activation Analysis (C.P.A.A.) for studying the behaviour of oxygen atoms in Czochralski silicon lattices under the influence of internal gettering and in different gaseous atmospheres. Association between ion channeling and C.P.A.A was also utilised for studying the influence of the growing conditions on concentration and position of carbon atoms at trace levels in the MOVPE Ga sub (1-x) Al sub x lattice. 6 figs., 1 tab., 32 refs.

  13. Death feigning by ducks in response to predation by red foxes (Vulpes fulva)

    Sargeant, A.B.; Eberhardt, L.E.

    1975-01-01

    Predation by captive red foxes (Vulpes fulva) on approximately 50 ducks comprised of five species was observed in tests conducted at the Northern Prairie Wildlife Research Center, Jamestown, North Dakota. Most ducks were attacked from a rear or lateral position and seized in the cervical or thoracic region. All birds became immobile (death-feigned) immediately when seized and with few exceptions remained motionless during prey-handling and for varying lengths of time thereafter. Initial death feints lasted from 20 sec to 14 min. Recovery was delayed by tactile, visual and, possibly, auditory cues from the foxes. Death-feigning birds appeared alert and often took advantage of escape opportunities. Twenty-nine birds survived initial capture and handling by the foxes. Naive foxes were wary of ducks during initial confrontations, but experienced foxes showed little hesitation in attacking them. After capture, most ducks were taken alive to lay-down sites where they were mouthed and often killed. Then the ducks were usually cached or taken to dens or pups. Several birds were cached alive. Red foxes appear to have adapted to the escape of death-feigning ducks by learning to kill some birds soon after capture and by the evolution of an appendage-severing behavior. Death feigning appears to be a highly developed antipredator behavior of ducks that facilitates the escape of some birds after capture by red foxes.

  14. Differential effects of coyotes and red foxes on duck nest success

    Sovada, Marsha A.; Sargeant, A.; Grier, J.W.

    1995-01-01

    Low recruitment rates prevail among ducks in the Prairie Pothole Region of North America, primarily because of high nest depredation rates. The red fox (Vulpes vulpes) is a major predator of duck eggs, but fox abundance is depressed by coyotes (Canis latrans). We tested the hypothesis that nest success of upland-nesting ducks is higher in areas with coyotes than in areas with red foxes. We conducted the study during 1990-92 in uplands of 36 areas managed for nesting ducks in North Dakota and South Dakota. Overall nest success averaged 32% (95% CI = 25-40) on 17 study areas where coyotes were the principal canid and 17% (CI = 11-25) on 13 study areas where red foxes were the principal canid (P = 0.01). Both canids were common on 6 other areas, where nest success averaged 25% (CI = 13-47). Habitat composition, predator communities with the exception of canids, and species composition of duck nests in coyote and red fox areas were similar overall. Upon examining only nests with greater than or equal to 6 eggs on the last visit prior to hatch or depredation, we determined nests with evidence characteristic of fox predation accounted for 4% of depredated nests in coyote areas and 27% in fox areas (P = 0.001). An expanding coyote population is contributing to higher overall nest success. Management of coyotes may be an effective method for increasing duck nest success.

  15. Configuration and stability of 1, 1-diamino-2, 2-dinitrothylene (FOX-7) embedded in graphene

    Wang, Yan Qun; Wang, Gui Xiang

    2016-01-01

    The configuration and stability of 1,1-diamino-2,2-dinitroethylene (FOX-7) embedded in graphene were studied using density functional theory with all-electron double numerical polarized basis sets. The results suggested that graphene had a greater impact on the planarity of FOX-7 molecules than did H-bonding. Under the synergistic effect of graphene and H-bonding, the geometry of H-bonded FOX-7 embedded in graphene was flatter than that of FOX-7 without H-bonds, which facilitated π–π stacking, as well as the stability of FOX-7 in graphene. The conjugated structure of FOX-7 contributed to its stability between layers of graphene. When the conjugated structure in FOX-7 was completely disrupted, the stabilization energy decreased by 48.6%. This theoretical work is useful for gaining new insights into the microscopic interaction of energetic molecules with graphene, and it will provide theoretical guidance for the encapsulation and storage of energetic materials

  16. FOX-2 Dependent Splicing of Ataxin-2 Transcript Is Affected by Ataxin-1 Overexpression

    Welzel, Franziska; Kaehler, Christian; Isau, Melanie; Hallen, Linda; Lehrach, Hans; Krobitsch, Sylvia

    2012-01-01

    Alternative splicing is a fundamental posttranscriptional mechanism for controlling gene expression, and splicing defects have been linked to various human disorders. The splicing factor FOX-2 is part of a main protein interaction hub in a network related to human inherited ataxias, however, its impact remains to be elucidated. Here, we focused on the reported interaction between FOX-2 and ataxin-1, the disease-causing protein in spinocerebellar ataxia type 1. In this line, we further evaluated this interaction by yeast-2-hybrid analyses and co-immunoprecipitation experiments in mammalian cells. Interestingly, we discovered that FOX-2 localization and splicing activity is affected in the presence of nuclear ataxin-1 inclusions. Moreover, we observed that FOX-2 directly interacts with ataxin-2, a protein modulating spinocerebellar ataxia type 1 pathogenesis. Finally, we provide evidence that splicing of pre-mRNA of ataxin-2 depends on FOX-2 activity, since reduction of FOX-2 levels led to increased skipping of exon 18 in ataxin-2 transcripts. Most striking, we observed that ataxin-1 overexpression has an effect on this splicing event as well. Thus, our results demonstrate that FOX-2 is involved in splicing of ataxin-2 transcripts and that this splicing event is altered by overexpression of ataxin-1. PMID:22666429

    2016-11-01

    Blood samples from 21 red foxes (Vulpes vulpes) and 8 hunting dogs from the same locality in the Czech Republic were examined for presence of Hepatozoon canis/Hepatozoon sp. The dogs were selected based on their close contact with foxes during fox bolting and because they had not traveled into known endemic areas. Using diagnostic PCR amplifying partial 18S rDNA fragment, Hepatozoon DNA was detected in 20 red foxes (95 %) and 4 dogs (50 %). From 8 positive foxes and 2 positive dogs, we obtained nearly complete 18S rDNA sequences. Phylogenetic analyses of these sequences revealed very low variability. Buffy coat smears from positive dogs were prepared and examined. No Hepatozoon gamonts were found. This study provides the first report of autochthonous infection of H. canis/Hepatozoon in dogs and foxes from the Czech Republic. Our study indirectly demonstrates cross infection between red foxes and dogs and confirms autochthonous infection of Hepatozoon canis in dogs living in a geographic area well outside the range of Rhipicephalus sanguineus sensu lato, which is so far the only known vector of H. canis in Europe.

  18. A Fork in the Path: Developing Therapeutic Inroads with FoxO Proteins

    Kenneth Maiese

    2009-01-01

    Full Text Available Advances in clinical care for disorders involving any system of the body necessitates novel therapeutic strategies that can focus upon the modulation of cellular proliferation, metabolism, inflammation and longevity. In this respect, members of the mammalian forkhead transcription factors of the O class (FoxOs that include FoxO1, FoxO3, FoxO4 and FoxO6 are increasingly being recognized as exciting prospects for multiple disorders. These transcription factors govern development, proliferation, survival and longevity during multiple cellular environments that can involve oxidative stress. Furthermore, these transcription factors are closely integrated with several novel signal transduction pathways, such as erythropoietin and Wnt proteins, that may influence the ability of FoxOs to act as a “double-edge sword” to sometimes promote cell survival, but at other times lead to cell injury. Here we discuss the fascinating but complex role of FoxOs during cellular injury and oxidative stress, progenitor cell development, fertility, angiogenesis, cardiovascular function, cellular metabolism and diabetes, cell longevity, immune surveillance and cancer.

  20. FoxO3A promotes metabolic adaptation to hypoxia by antagonizing Myc function

    Jensen, Kim Steen; Binderup, Tina; Jensen, Klaus Thorleif

    2011-01-01

    Exposure of metazoan organisms to hypoxia engages a metabolic switch orchestrated by the hypoxia-inducible factor 1 (HIF-1). HIF-1 mediates induction of glycolysis and active repression of mitochondrial respiration that reduces oxygen consumption and inhibits the production of potentially harmful...... tumour tissue in vivo and that FoxO3A short-hairpin RNA (shRNA)-expressing xenograft tumours are decreased in size and metabolically changed. Our findings define a novel mechanism by which FoxO3A promotes metabolic adaptation and stress resistance in hypoxia....... reactive oxygen species (ROS). Here, we show that FoxO3A is activated in hypoxia downstream of HIF-1 and mediates the hypoxic repression of a set of nuclear-encoded mitochondrial genes. FoxO3A is required for hypoxic suppression of mitochondrial mass, oxygen consumption, and ROS production and promotes...... cell survival in hypoxia. FoxO3A is recruited to the promoters of nuclear-encoded mitochondrial genes where it directly antagonizes c-Myc function via a mechanism that does not require binding to the consensus FoxO recognition element. Furthermore, we show that FoxO3A is activated in human hypoxic...

  1. High activity antioxidant enzymes protect flying-fox haemoglobin against damage: an evolutionary adaptation for flight?

    Reinke, N B; O'Brien, G M

    2006-11-01

    Flying-foxes are better able to defend haemoglobin against autoxidation than non-volant mammals such as sheep. When challenged with the common physiological oxidant, hydrogen peroxide, haemolysates of flying-fox red blood cells (RBC) were far less susceptible to methaemoglobin formation than sheep. Challenge with 1-acetyl-2-phenylhydrazine (APH) caused only half as much methaemoglobin formation in flying-fox as in ovine haemolysates. When intact cells were challenged with phenazine methosulfate (PMS), flying-fox RBC partially reversed the oxidant damage, and reduced methaemoglobin from 40 to 20% over 2 h incubation, while ovine methaemoglobin remained at 40%. This reflected flying-fox cells' capacity to replenish GSH fast enough that it did not deplete beyond 50%, while ovine RBC GSH was depleted to around 20%. The greater capacity of flying-foxes to defend haemoglobin against oxidant damage may be explained in part by antioxidant enzymes catalase, superoxide dismutase and cytochrome-b ( 5 ) reductase having two- to four-fold higher activity than in sheep (P foxes.

  2. Diets of swift foxes (Vulpes velox) in continuous and fragmented prairie in Northwestern Texas

    Kamler, J.F.; Ballard, W.B.; Wallace, M.C.; Gipson, P.S.

    2007-01-01

    Distribution of the swift fox (Vulpes velox) has declined dramatically since the 1800s, and suggested causes of this decline are habitat fragmentation and transformation due to agricultural expansion. However, impacts of fragmentation and human-altered habitats on swift foxes still are not well understood. To better understand what effects these factors have on diets of swift foxes, scats were collected in northwestern Texas at two study sites, one of continuous native prairie and one representing fragmented native prairie interspersed with agricultural and fields in the Conservation Reserve Program. Leporids, a potential food source, were surveyed seasonally on both sites. Diets of swift foxes differed between sites; insects were consumed more on continuous prairie, whereas mammals, birds, and crops were consumed more on fragmented prairie. Size of populations of leporids were 2-3 times higher on fragmented prairie, and swift foxes responded by consuming more leporids on fragmented (11.1% frequency occurrence) than continuous (3.8%) prairie. Dietary diversity was greater on fragmented prairie during both years of the study. Differences in diets between sites suggested that the swift fox is an adaptable and opportunistic feeder, able to exploit a variety of food resources, probably in relation to availability of food. We suggest that compared to continuous native prairie, fragmented prairie can offer swift foxes a more diverse prey base, at least within the mosaic of native prairie, agricultural, and fields that are in the Conservation Reserve Program.

  3. Habitat selection and diurnal refugia of gray foxes in southwestern Georgia, USA.

    Nicholas R Deuel

    Full Text Available Understanding habitat selection of gray foxes (Urocyon cinereoargenteus is essential to evaluate their potential response to changes in land use and predator communities. Few studies have evaluated temporal habitat selection or explicitly identified habitats used by gray foxes for diurnal refugia. We used GPS collars to obtain location data for 34 gray foxes (20 males and 14 females from February 2014 to December 2015 to evaluate temporal (seasonal and diel habitat selection and selection of diurnal refugia in southwestern Georgia, USA. We analyzed habitat selection at 2 levels, selection of a core area within the home range and selection of locations within the home range. Habitat selection was non-random (P 0.05. Hardwoods, human use (i.e., areas associated with regular human activity such as buildings, lawns, parking areas, etc., and roads were selected (P 0.05. Selection of habitats for diurnal refugia did not vary seasonally or by sex (P > 0.05, with foxes selecting (P < 0.05 areas near hardwood forests, roads, agriculture, human use, pastures/food plots, and shrub scrub habitats. Gray foxes were observed on the ground while resting, and we found no evidence of gray foxes diurnally resting in trees. Our results suggest that on our study area, gray foxes are an edge species that prefer forests with a hardwood component in areas near human use and roads.

  4. Sand Floor for Farmed Blue Foxes: Effects on Claws, Adrenal Cortex Function, Growth and Fur Properties

    Leena Ahola

    2009-01-01

    Full Text Available Farmed blue foxes (Vulpes lagopus are traditionally housed on mesh floors where they are unable to perform certain species-specific behaviours, such as digging, which may compromise the animals' welfare. This study describes how a possibility to use in-cage sand floor affects welfare-related variables like growth of the claws, adrenal cortex function, and fur properties in juvenile blue foxes. The foxes (N=32 were housed in male-female sibling pairs in an outdoor fur animal shed in cage systems consisting of two traditional fox cages. For the eight male-female sibling pairs of the Control group, there was a mesh floor in both cages of each cage system, whereas for the eight pairs of the Sand group there was a mesh floor in one cage and a 30–40 cm deep earth floor in the other cage. The results show that sand floor is beneficial for the wearing of the claws of foxes. Furthermore, an early experience of sand floor may have positive effects on the foxes' fur development. The results, however, also suggest that there might appear welfare problems observed as disturbed claw growth and increased adrenal cortex activation if foxes that are once provided with clean and unfrozen sand floor are not allowed to enjoy this floor all the time.

    Mr Pierre Gadonneix, President of Gaz de France, presented 'The Gaz de France Group in the new European context: opportunities and strategy of a major gas operator' during the 21. world gas congress, which was held in Nice from 6. to 9. June 2000. A few weeks from the liberalization of the gas market in Europe. It seems interesting to publish this article, which very pertinently presents the point of view of the leading French gas operator. We also considered it right to publish the presentation of Mr Burckhard Bergmann, President of Eurogas, who presented the European vision. To complete this panorama of the gas situation, we are also publishing news about the international gas situation in 1999, written by Marie-Francoise Chabrelie of Cedigaz which is summarized here under: in a changing environment, characterized by privatisation, the deregulation and the opening up of markets (Europe, Australia), natural gas has progressively gained ground in the world energy market. This trend was confirmed in 1999. Major discoveries open the way to new projects for local use and export. In spite of the uncertainties regarding the situation in countries of the ex-Soviet Union, several favourable factors, including economic recovery in Asia faster than forecast, indicate a growth hypothesis ranging from 2.5% for this year.

  7. A content analysis of smokeless tobacco coverage in U.S. newspapers and news wires.

    Wackowski, Olivia A; Lewis, M Jane; Delnevo, Cristine D; Ling, Pamela M

    2013-07-01

    Research attention on smokeless tobacco (SLT) has focused on SLT use, health risks, harm-reduction potential, and risk perceptions, but few studies have examined mediated communications about SLT. This study aims to contribute to the literature by providing the first description of SLT coverage in the news, an important communication channel given its ability to educate and shape public opinion about tobacco issues. A content analysis was conducted on SLT-related news and opinion articles between 2006 and 2010 from top circulating national and state newspapers and select news wires. Articles were coded for the main SLT topic, SLT risk references, and slant of opinion articles. SLT was discussed in news/feature articles (n = 677) in terms of business (28%), new products, product regulation and harm reduction (19%), prevention/cessation (11.4%), taxation (10.2%), profiles/trends in use (9%), bans (8.1%), and tobacco industry promotional activities (4.9%). Health risk references (i.e., addictiveness, carcinogenicity, and specific health effects including oral cancer) were found in 40% of articles, though frequency differed by article topic. Although the majority of opinion articles (n = 176) conveyed an anti-SLT slant (64%), 25.6% were pro-SLT. SLT topics of both national and local importance are covered in the news. Public health professionals can participate in SLT coverage by sending in press releases about new study findings, events, or resources and by submitting opinion pieces to share views or respond to previous coverage. Research on SLT news should continue given its potential to shape the public's SLT knowledge and opinions.

  8. A Content Analysis of Smokeless Tobacco Coverage in U.S. Newspapers and News Wires

    2013-01-01

    Introduction: Research attention on smokeless tobacco (SLT) has focused on SLT use, health risks, harm-reduction potential, and risk perceptions, but few studies have examined mediated communications about SLT. This study aims to contribute to the literature by providing the first description of SLT coverage in the news, an important communication channel given its ability to educate and shape public opinion about tobacco issues. Methods: A content analysis was conducted on SLT-related news and opinion articles between 2006 and 2010 from top circulating national and state newspapers and select news wires. Articles were coded for the main SLT topic, SLT risk references, and slant of opinion articles. Results: SLT was discussed in news/feature articles (n = 677) in terms of business (28%), new products, product regulation and harm reduction (19%), prevention/cessation (11.4%), taxation (10.2%), profiles/trends in use (9%), bans (8.1%), and tobacco industry promotional activities (4.9%). Health risk references (i.e., addictiveness, carcinogenicity, and specific health effects including oral cancer) were found in 40% of articles, though frequency differed by article topic. Although the majority of opinion articles (n = 176) conveyed an anti-SLT slant (64%), 25.6% were pro-SLT. Conclusions: SLT topics of both national and local importance are covered in the news. Public health professionals can participate in SLT coverage by sending in press releases about new study findings, events, or resources and by submitting opinion pieces to share views or respond to previous coverage. Research on SLT news should continue given its potential to shape the public’s SLT knowledge and opinions. PMID:23288875

    Hepatozoon canis is a protozoan tick-borne pathogen of dogs and wild canids. Hepatozoon spp. have been reported to infect foxes in different continents and recent studies have mostly used the polymerase chain reaction (PCR) for the detection and characterization of the infecting species. Surveying red foxes (Vulpes vulpes) may contribute to better understanding the epidemiology of canine vector-borne diseases, including hepatozoonosis caused by H. canis in domestic dogs. The present study investigated the prevalence of Hepatozoon spp. by means of histopathology and molecular analysis of different tissues in red foxes from different parts of Portugal. Blood and tissues including bone marrow, heart, hind leg muscle, jejunum, kidney, liver, lung, popliteal or axillary lymph nodes, spleen and/or tongue were collected from 91 red foxes from eight districts in northern, central and southern Portugal. Tissues were formalin-fixed, paraffin-embedded, cut and stained with hematoxylin and eosin. Polymerase chain reaction (PCR) amplified a ~650 bp fragment of the 18S rRNA gene of Hepatozoon spp. and the DNA products were sequenced. Hepatozoon canis was detected in 68 out of 90 foxes (75.6%) from all the sampled areas by PCR and sequencing. Histopathology revealed H. canis meronts similar in shape to those found in dogs in the bone marrow of 11 (23.4%) and in the spleen of two (4.3%) out of 47 foxes (p = 0.007). All the 11 foxes found positive by histopathology were also positive by PCR of bone marrow and/or blood. Positivity by PCR (83.0%) was significantly higher (p Hepatozoon canis was found to be highly prevalent in red fox populations from northern, central and southern Portugal. Detection of the parasite by histopathology was significantly less sensitive than by PCR. Red foxes are a presumptive reservoir of H. canis infection for domestic dogs.

  10. Inhibition of FoxO transcriptional activity prevents muscle fiber atrophy during cachexia and induces hypertrophy

    Reed, Sarah A.; Sandesara, Pooja B.; Senf, Sarah M.; Judge, Andrew R.

    2012-01-01

    Cachexia is characterized by inexorable muscle wasting that significantly affects patient prognosis and increases mortality. Therefore, understanding the molecular basis of this muscle wasting is of significant importance. Recent work showed that components of the forkhead box O (FoxO) pathway are increased in skeletal muscle during cachexia. In the current study, we tested the physiological significance of FoxO activation in the progression of muscle atrophy associated with cachexia. FoxO-DNA binding dependent transcription was blocked in the muscles of mice through injection of a dominant negative (DN) FoxO expression plasmid prior to inoculation with Lewis lung carcinoma cells or the induction of sepsis. Expression of DN FoxO inhibited the increased mRNA levels of atrogin-1, MuRF1, cathepsin L, and/or Bnip3 and inhibited muscle fiber atrophy during cancer cachexia and sepsis. Interestingly, during control conditions, expression of DN FoxO decreased myostatin expression, increased MyoD expression and satellite cell proliferation, and induced fiber hypertrophy, which required de novo protein synthesis. Collectively, these data show that FoxO-DNA binding-dependent transcription is necessary for normal muscle fiber atrophy during cancer cachexia and sepsis, and further suggest that basal levels of FoxO play an important role during normal conditions to depress satellite cell activation and limit muscle growth.—Reed, S. A., Sandesara, P. B., Senf, S. F., Judge, A. R. Inhibition of FoxO transcriptional activity prevents muscle fiber atrophy during cachexia and induces hypertrophy. PMID:22102632

  11. FoxO1 and HNF-4 are involved in regulation of hepatic glucokinase gene expression by resveratrol.

    Ganjam, Goutham Kumar; Dimova, Elitsa Y; Unterman, Terry G; Kietzmann, Thomas

    2009-11-06

    Resveratrol, a polyphenol derived from grapes, exerts important effects on glucose and lipid metabolism, yet detailed mechanisms mediating these effects remain unknown. The liver plays a central role in energy homeostasis, and glucokinase (GK) is a key enzyme involved in glucose utilization. Resveratrol activates SIRT1 (sirtuin 1), which promotes deacetylation of the forkhead transcription factor FoxO1. Previously, we reported that FoxO1 can suppress and that HNF-4 can stimulate GK expression in the liver. Here, we examined the role of FoxO1 and HNF-4 in mediating resveratrol effects on liver GK expression. Resveratrol suppressed hepatic GK expression in vivo and in isolated hepatocytes, and knocking down FoxO1 with shRNAs disrupted this effect. Reporter gene, gel shift, supershift assay, and chromatin immunoprecipitation studies show that FoxO1 binds to the GK promoter and that the interplay between FoxO1 and HNF-4 within the GK promoter is essential for mediating the effects of resveratrol. Resveratrol promotes deacetylation of FoxO1 and enhances its recruitment to the FoxO-binding element. Conversely, resveratrol suppresses recruitment of HNF-4 to its binding site, and knockdown of FoxO1 blocks this effect of resveratrol. Coprecipitation and chromatin immunoprecipitation studies show that resveratrol enhances interaction between FoxO1 and HNF-4, reduces binding of HNF-4 to its own site, and promotes its recruitment to the FoxO site in a FoxO1-dependent manner. These results provide the first evidence that resveratrol represses GK expression via FoxO1 and that the interaction between FoxO1 and HNF-4 contributes to these effects of resveratrol.

    2015-01-01

    Corynebacterium (C.) ulcerans could be isolated from the spleen of a red fox (Vulpes vulpes) that had been found dead in the state of Baden-Württemberg, Germany. Pathohistological examination suggested that the fox had died of distemper, as was confirmed by PCR. The isolate was identified biochemically, by MALDI-TOF MS, FT-IR and by partial 16S rRNA, rpoB and tox gene sequencing. Using the Elek test the C. ulcerans isolate demonstrated diphtheria toxin production. FT-IR and sequencing data obtained from the C. ulcerans isolate from the red fox showed higher similarity to isolates from humans than to those from wild game.

  15. Different expression of FoxM1 in human benign and malignant pleural effusion.

    Tang, Zhonghao; Li, Hongqing; Zhu, Huili; Bai, Chunxue

    2015-01-01

    The aims of this study were as follows: to analyze the forkhead box M1 (FoxM1) expression in benign and malignant pleural effusion by reverse transcription-polymerase chain reaction assay (RT-PCR); to explore the role of FoxM1 in formation and progress in malignant pleural effusion, and whether there is significant difference in expression level of FoxM1 between benign and malignant pleural effusion; to seek a gene marker diagnostically useful to identify benign and malignant pleural effusion in diagnosis and treatment of pleural effusion; and to collect expression level data of FoxM1 in 23 malignant pleural effusion samples (17 adenocarcinoma samples, four squamous carcinoma samples and two small cell lung carcinoma samples) and 15 benign pleural effusion samples (11 inflammatory pleural effusions, two transudates, two tuberculous pleural effusions) by RT-PCR. Among all 38 samples, average FoxM1 expression level of benign pleural effusions is (235.09 ± 59.99), while malignant pleural effusions (828.77 ± 109.76). Among 23 malignant samples, average FoxM1 expression level is (529.27 ± 75.85) in samples without cytological diagnostic evidence, while (1,218.12 ± 167.21) in samples with cytological diagnostic evidence. Differences of FoxM1 expression level between benign pleural effusions and malignant ones have statistical significance. There is an area of 0.881 under the receiver-operating characteristic curve, which verifies the accuracy of using FoxM1 expression level as diagnostic index to identify benign and malignant pleural effusions. According to our study, diagnostic sensitivity and specificity for FoxM1 expression level at 418.1 were 82.6 and 86.7 %, respectively, while 47.8 and 100 %, respectively, at 768.7. FoxM1 expression level in malignant pleural effusions is significantly higher than in benign ones. This study provides a new approach in clinical diagnosis, with FoxM1 as a specific molecule marker to identify benign and malignant pleural

    Fuglei, E.; Bustnes, J.O.; Hop, H.; Mork, T.; Bjoernfoth, H.; Bavel, B. van

    2007-01-01

    Adipose tissues from 20 arctic foxes (Alopex lagopus) of both sexes from Svalbard were analysed for polybrominated diphenyl ether (PBDE), polychlorinated biphenyl (PCB), p,p'-dichlorodiphenyltrichloroethane (DDE), chlordane, and hexachlorobenzene (HCB) concentrations. Gender (0.43 15 N from muscle samples and showed significantly positive relationship with all contaminants, with the exception of HCB concentrations. This indicates that foxes feeding at high trophic levels had higher tissue contaminant levels as a result of bioaccumulation in the food chain. - High contaminant concentrations in the coastal ecotype of arctic fox may cause toxic health effects due to huge annual cyclic variation in storage and mobilisation of adipose tissue

  4. Television news coverage of obesity in China, 1982-2009.

    Yi, Zhe; Xu, Rui Qing; Zhao, Kun; Li, Ke Ji

    2012-06-01

    The purpose of this study was to explore how obesity was covered in television news in China, including the trends over time and the characteristics of obesity-related news. The frame analysis was adopted to assess the content of obesity-related news broadcasted in China Central Television (CCTV) from 1982 to 2009. To investigate the characteristics of the news, the obesity-related news was divided into subgroups according to populations concerned, as well as the period in which the news was broadcasted. The differences between subgroups were examined. A total of 1 599 pieces of news reported obesity, in which 1 278 pieces (79.92%) aired in "wealthy" period (2006-2009). More news was concerned with adults (1 134, 70.92%). "Individual behavior" dominated most of the cause frames (389, 24.33%), solution frames (522, 32.65%), and responsibility frames (860, 53.78%). There was more news mentioning individual factors in news aired in "wealthy" period and news concerning children. The coverage of social-structure causes was higher in news concerning children, while the coverage of social-structure solutions was higher in news concerning children and news aired in "wealthy" period. Although the coverage of obesity was modest, it showed an incremental trend as the economy grew. Obesity was mostly depicted as an individual problem in terms of responsibility, causes and solutions.

  6. Channel box

    Tanabe, Akira.

    1993-01-01

    In a channel box of a BWR type reactor, protruding pads are disposed in axial position on the lateral side of a channel box opposing to a control rod and facing the outer side portion of the control rod in a reactor core loaded state. In the initial loading stage of fuel assemblies, channel fasteners and spacer pads are abutted against each other in the upper portion between the channel boxes sandwiching the control rod therebetween. Further, in the lower portion, a gap as a channel for the movement of the control rod is ensured by the support of fuel support metals. If the channel box is bent toward the control rod along with reactor operation, the pads are abutted against each other to always ensure the gap through which the control rod can move easily. Further, when the pads are brought into contact with each other, the bending deformation of the channel box is corrected by urging to each other. Thus, the control rod can always be moved smoothly to attain reactor safety operation. (N.H.)

  7. Local television news reporting of kidney disease.

    Jaffery, Jonathan B; Jacobson, Lynn M; Goldstein, Kenneth M; Pribble, James M

    2006-12-01

    Local television is the primary news source for the majority of Americans. This study aims to describe how local news reports on kidney disease. Using our searchable database of health-related late local news segments from 2002, we identified stories with the key words kidney, hypertension, blood pressure, or diabetes. This database is a representative sample of the late local news on 122 stations in the 50 largest US media markets, comprising 60% of the population. The content of each identified story was reviewed to determine whether it mentioned: (1) chronic kidney disease (CKD), (2) screening for kidney disease, or (3) kidney disease as a potential complication (for blood pressure- or diabetes-related stories). Only 2 of 1,799 database news stories (0.11%) included "kidney" as a summary key word; neither referred to CKD, screening, or complications of other diseases. Of 19 stories about hypertension or blood pressure (1.06% of all stories) and the 14 stories about diabetes (0.78% of all stories), none mentioned these criteria. Despite efforts to increase public awareness of and screening for CKD, local television news (the most important news source for a majority of Americans) did little to help achieve these goals. Further work will be needed to confirm whether this paucity of coverage varies over time and determine why so little attention is given to CKD. Educating physicians and public relations personnel who advocate for kidney disease about journalists' needs may be an important step to help advance public awareness of CKD.

  8. News Authorship and News Sources: Impacts on Environmental Coverage in The Nigerian Press

    Ogadimma C. Emenyeonu

    2017-07-01

    Full Text Available This study examines the impacts of news authorship and news sources on environmental coverage in the Nigerian press to shed light on the roles they play in news construction. The study finds that journalists in conjunction with policy makers are the catalyst for environmental information, whereas citizens who are pivotal in creating relevant public opinion on environmental issues are left behind. The study reveals that investigative reporting lacks in environmental coverage because most coverage are events driven which explains why environmental news is reported as straight news and as such journalists rely heavily on official sources rather than subsidiary sources. The study opines that for proper environmental coverage, journalists must choose sources from both main and subsidiary actors and revert to proactive, investigative and interpretive reporting so as to make environmental stories relatable to the intended audiences.

  10. Home range defense in the red fox, Vulpes vulpes L

    Preston, E.M.

    1975-01-01

    This paper describes the home range defense behavior observed when nonresident male red foxes were introduced into established home ranges of resident male-female pairs. In 12 observation periods, four intruders were introduced to each of three mated pairs which had been given three weeks to acclimate to a 4.05-hectare, fenced enclosure. The residents centered their activities around a natural den and the frequency of intruder-resident encounters decreased rapidly with increasing distance from the den. The primary home range defense was continual harassment of the intruders by the resident males through agonistic displays and chases. Physical contact was rare. Even though the resident males were dominant in less than a majority of the interactions observed, they were usually successful in displacing the intruders within a few hours. The resident females seldom interacted with the intruders.

  11. Spatiotemporal distribution of rabies in Arctic foxes in Greenland

    Raundrup, Katrine; Moshøj, Charlotte Margaret; Wennerberg, Sanne

    2015-01-01

    The temporal occurrence, spatial distribution, spread, and prevalence of rabies in Arctic foxes, Vulpes lagopus, in Greenland were studied using historical observations from 1969 to 2011 and survey data collected in the winters 1992 and 1993. Regionally, the prevalence of rabies ranged between 0...... and 7.1 %. Wavelet analysis was used to identify periodicities in the abundance of rabies cases based on the historical observations. No general length of the cyclic interval of rabies occurrences in Greenland could be demonstrated. The frequency of outbreaks was found to be variable but can be grouped...... as short (less than 5 years), medium (5–10 years), and long (more than 10 years). Moreover, rabies outbreaks in neighboring regions were found to be more closely correlated compared to regions further apart. In West Greenland, the temporal outbreaks of rabies were found to occur along a north...

  14. [Influence of the news media].

    Camarena Luna, R

    1991-01-01

    Newspapers, in addition to news, also cover topics of permanent interest to their readers. One such topic is sexuality. The appearance of the incurable sexually transmitted disease AIDS obliges a reconsideration of the complex and contradictory concept of sexuality. Sexuality is not often spoken of openly; rather, it is secret, hidden, and referred to obliquely. Sexuality is the manifestation and satisfaction of the sexual impulses common to all individuals. Sexuality is determined by anatomic and physiologic aspects and also by the knowledge, experiences, values, and norms internalized by the individual living in a social group. Messages about sexual conduct are constantly being received. This social part of sexuality supported by customs and morals is the part that is directly influenced by communications media. An important objective of the media is to create awareness and mold opinions. Mexico's large national circulation newspapers present different points of view about sexuality. Newspapers that continually critique homosexual practices and those that demonstrate implicit approval of pornographic videos by advertising them both present attitudes without providing opportunities to reason, compare, or support opinions. Sexuality is usually referred to indirectly and superficially in the press. Sex education may be mentioned but not the erotic implications of sexuality, and acceptance or opposition to use of condoms may be discussed without mention of psychological barriers to their use. The national press is not prepared to propose new attitudes toward sexuality in the age of AIDS. Only 1 national newspaper in Mexico regularly provides information on AIDS including aspects related to sexual pleasure and responsibility and safer sex. The majority continue with their pre-AIDS coverage of sexuality, using it to arouse interest but providing little depth. Newspapers should provide more extensive coverage on sexuality and its modifications due to AIDS, a reality

    2017-01-01

    Social media for news consumption is a double-edged sword. On the one hand, its low cost, easy access, and rapid dissemination of information lead people to seek out and consume news from social media. On the other hand, it enables the wide spread of "fake news", i.e., low quality news with intentionally false information. The extensive spread of fake news has the potential for extremely negative impacts on individuals and society. Therefore, fake news detection on social media has recently b...

  16. Surface channeling

    Sizmann, R.; Varelas, C.

    1976-01-01

    There is experimental evidence that swift light ions incident at small angles towards single crystalline surfaces can lose an appreciable fraction of their kinetic energy during reflection. It is shown that these projectiles penetrate into the bulk surface region of the crystal. They can travel as channeled particles along long paths through the solid (surface channeling). The angular distribution and the depth history of the re-emerged projectiles are investigated by computer simulations. A considerable fraction of the penetrating projectiles re-emerges from the crystal with constant transverse energy if the angle of incidence is smaller than the critical angle for axial channeling. Analytical formulae are derived based on a diffusion model for surface channeling. A comparison with experimental data exhibits the relevance of the analytical solutions. (Auth.)

    2012-12-01

    NASA's Earth Observatory (EO) is an online publication featuring NASA Earth science news and images. Since its inception in 1999, the EO team has relied heavily on near-real time satellite data to publish imagery of breaking news events, such as volcanoes, floods, fires, and dust storms. Major news outlets (Associated Press, The Weather Channel, CNN, etc.) have regularly republished Earth Observatory imagery in their coverage of events. Because of the nature of modern 24-hour news cycle, media almost always want near-real time coverage; providing it depends heavily on rapid data turnaround, user-friendly data systems, and fast data access. We will discuss how we use near-real time data and provide examples of how data systems have been transformed in the past 13 years.

    Eucoleus boehmi (Nematoda: Capillariidae) occurs in the nasal conchae and paranasal sinuses of wild and domestic canids. We surveyed the red fox ( Vulpes vulpes ) on Prince Edward Island, Canada, for E. boehmi infection and characterized the associated histopathology. Nasal capillarid infections were detected based on histologic examination of three coronal sections of the nasal cavity and by centrifugal flotation examination (CFE) of rectal feces. Capillarids were detected in histologic sections in 28 of 36 (78%) foxes; detection occurred most frequently in the caudal section (28 foxes) and least in the rostral section (10 foxes). Adult worm morphology was typical for capillarids (stichosome esophagus, bacillary bands, bipolar plugged eggs); E. boehmi eggs were specifically identified based on the characteristic pitted shell wall surface. Adult worms were detected in histologic sections in all 28 and E. boehmi eggs in 21 of the positive foxes. No eggs of Eucoleus aerophilus were observed in any of the sections. Affected foxes had an eosinophilic and lymphoplasmacytic rhinitis with goblet cell hyperplasia. Eggs of E. aerophilus were detected on CFE in 20 of 36 (56%) foxes; 19 of the histologically positive foxes were coinfected with E. aerophilus. Eggs of E. boehmi were detected on CFE in 26 of 36 (72%) foxes and were consistent in size and morphology with those described from wild canids, but they differed from those reported from cases of infection in dogs. Prevalence based on identification of eggs on histologic section or CFE indicated 27 of 36 (75%) red foxes examined were infected with E. boehmi.

  19. Measuring the Interestingness of News Articles

    Pon, R K; Cardenas, A F; Buttler, D J

    2007-09-24

    An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

    Using a modified epidemiological model, the dissemination of news by media agents after the occurrence of large scale disasters was studied. A modified compartmented model was developed in a previous paper presented at INAC 2007. There it used to study to the Chernobyl's nuclear accident (1986) and the Concorde airplane crash (2000). Now the model has been applied to a larger and more diverse group of events - nuclear, non-nuclear and naturally caused disasters. To be comprehensive, old and recent events from various regions of the world were selected. A more robust news repository was used, and improved search techniques were developed to ensure that the scripts would not count false positive news. The same model was used but with improved non-linear embedded simulation optimization algorithms to generate the parameters of interest for our model. Individual parameters and some specific combination of them allow some interesting perceptions on how the nature of the accident / disaster gives rise to different profiles of growth and decay of the news. In our studies events involving nuclear causes generate news repercussion with more explosive / robust surge profiles and longer decaying tails than those of other natures. As a consequence of these differences, public opinion and policy makers are also much more sensitive to some issues than to others. The model, through its epidemiological parameters, shows in quantitative manner how 'nervous' the media content generators are with respect to nuclear installations and how resilient this negative feelings about nuclear is.

  1. News exposure predicts anti-Muslim prejudice.

    Shaver, John H; Sibley, Chris G; Osborne, Danny; Bulbulia, Joseph

    2017-01-01

    News coverage of Islamic extremism is reigniting debates about the media's role in promoting prejudice toward Muslims. Psychological theories of media-induced prejudice date to the 1950's, and find support from controlled experiments. However, national-scale studies of media effects on Muslim prejudice are lacking. Orthogonal research investigating media-induced prejudice toward immigrants has failed to establish any link. Moreover, it has been found that people interpret the news in ways that confirm pre-existing attitudes, suggesting that media induced Muslim prejudice in liberal democracies is unlikely. Here, we test the association between news exposure and anti-Muslim prejudice in a diverse national sample from one of the world's most tolerant societies, where media effects are least likely to hold (N = 16,584, New Zealand). In support of media-induced Islamophobia, results show that greater news exposure is associated with both increased anger and reduced warmth toward Muslims. Additionally, the relationship between media exposure and anti-Muslim prejudice does not reliably vary with political ideology, supporting claims that it is widespread representations of Muslims in the news, rather than partisan media biases, that drives anti-Muslim prejudice.

  3. Helios, and not FoxP3, is the marker of activated Tregs expressing GARP/LAP.

    Elkord, Eyad; Abd Al Samid, May; Chaudhary, Belal

    2015-08-21

    Regulatory T cells (Tregs) are key players of immune regulation/dysregulation both in physiological and pathophysiological settings. Despite significant advances in understanding Treg function, there is still a pressing need to define reliable and specific markers that can distinguish different Treg subpopulations. Herein we show for the first time that markers of activated Tregs [latency associated peptide (LAP) and glycoprotein A repetitions predominant (GARP, or LRRC32)] are expressed on CD4+FoxP3- T cells expressing Helios (FoxP3-Helios+) in the steady state. Following TCR activation, GARP/LAP are up-regulated on CD4+Helios+ T cells regardless of FoxP3 expression (FoxP3+/-Helios+). We show that CD4+GARP+/-LAP+ Tregs make IL-10 immunosuppressive cytokine but not IFN-γ effector cytokine. Further characterization of FoxP3/Helios subpopulations showed that FoxP3+Helios+ Tregs proliferate in vitro significantly less than FoxP3+Helios- Tregs upon TCR stimulation. Unlike FoxP3+Helios- Tregs, FoxP3+Helios+ Tregs secrete IL-10 but not IFN-γ or IL-2, confirming they are bona fide Tregs with immunosuppressive characteristics. Taken together, Helios, and not FoxP3, is the marker of activated Tregs expressing GARP/LAP, and FoxP3+Helios+ Tregs have more suppressive characteristics, compared with FoxP3+Helios- Tregs. Our work implies that therapeutic modalities for treating autoimmune and inflammatory diseases, allergies and graft rejection should be designed to induce and/or expand FoxP3+Helios+ Tregs, while therapies against cancers or infectious diseases should avoid such expansion/induction.

  4. Gastrointestinal helminths of arctic foxes (Alopex lagopus) from different bioclimatological regions in Greenland

    Kapel, C. M O; Nansen, P.

    1996-01-01

    Nine species of gastrointestinal helminths were recovered from 254 arctic foxes (Alopex lagopus) from 8 different localities in Greenland. Prevalences of infection with the helminth species differed from area to area: Toxascaris leonina (3968%), Strongyloides stercoralis (0-14%), Mesocestoides...... of Greenland. In general, the composition of the helminth fauna of arctic foxes in Greenland showed distinct differences geographically. Thus, the diversity of helminth species in foxes caught in the northern districts of Greenland seems lower than in the southern districts; only nematode species with direct...... life cycles were represented equally in all parts of the country. The diversity of the surrounding fauna, and thereby the food items available for the foxes, seems to determine the spectrum of helminth species. Helminths requiring rodents as intermediate hosts were absent on the west coast, even...

    2017-04-05

    Severe lung strongylosis was detected in a wild red fox (Vulpes vulpes) (1/12) from Apulia (Italy). We performed routine diagnostics on 12 foxes found dead in Apulia. Eleven of them showed lesions consistent with a vehicle collision. However, the remaining fox appeared to have died from other causes. At necropsy we observed, catarrhal enteritis, fatty liver, lung congestion with some areas rm in consistence and brain haemorrhages and malacia. Histopathology revealed lung brosis with mononucleate cells in ltration, thrombosis a several larval nematodes spread in the parenchyma, interstitial nephritis, interstitial myocarditis, encephalitis, encephalomalacia, and a brain granuloma. The larvae recovered from the lung parenchyma were identi ed as the rst stage larvae of Angiostrongylus vasorum. This is the rst documented report of angiostrongylosis in a fox in Southern Italy.

    daf-16 /FoxO is required to survive starvation in Caenorhabditis elegans , but how daf-16I FoxO promotes starvation resistance is unclear. We show that daf-16 /FoxO restructures carbohydrate metabolism by driving carbon flux through the glyoxylate shunt and gluconeogenesis and into synthesis of trehalose, a disaccharide of glucose. Trehalose is a well-known stress protectant, capable of preserving membrane organization and protein structure during abiotic stress. Metabolomic, genetic, and pharmacological analyses confirm increased trehalose synthesis and further show that trehalose not only supports survival as a stress protectant but also serves as a glycolytic input. Furthermore, we provide evidence that metabolic cycling between trehalose and glucose is necessary for this dual function of trehalose. This work demonstrates that daf-16 /FoxO promotes starvation resistance by shifting carbon metabolism to drive trehalose synthesis, which in turn supports survival by providing an energy source and acting as a stress protectant.

  8. Spark Channels

    1968-04-15

    A brief summary is given of the principal methods used for initiating spark channels and the various highly time-resolved techniques developed recently for studies with nanosecond resolution. The importance of the percentage overvoltage in determining the early history and subsequent development of the various phases of the growth of the spark channel is discussed. An account is then given of the recent photographic, oscillographic and spectroscopic investigations of spark channels initiated by co-axial cable discharges of spark gaps at low [{approx} 1%] overvoltages. The phenomena observed in the development of the immediate post-breakdown phase, the diffuse glow structure, the growth of the luminous filament and the final formation of the spark channel in hydrogen are described. A brief account is also given of the salient features emerging from corresponding studies of highly overvolted spark gaps in which the spark channel develops from single avalanche conditions. The essential differences between the two types of channel formation are summarized and possible explanations of the general features are indicated. (author)

  9. Thrilling News Revisited: The Role of Suspense for the Enjoyment of News Stories.

    Kaspar, Kai; Zimmermann, Daniel; Wilbers, Anne-Kathrin

    2016-01-01

    Previous research on news perception has been dominated by a cognitively oriented perspective on reception processes, whereas emotions have been widely neglected. Consequently, it has remained open which features of a news story might elicit affective responses and hence modulate news perception, shifting the focus to the emotional potential of the narrative. According to the affective-disposition theory, the experience of suspense is the striving force of immersion in fictional dramas. Thereby, a positive affective disposition toward the protagonist of a story and a high likelihood of a bad ending should increase suspense that, in turn, should positively influence reading appreciation and lingering interest in the story. We investigated whether suspense and its determinants also play such a key role in the context of news stories. Study 1 ( n = 263) successfully replicated results of an earlier study, whereas Studies 2 ( n = 255) and 3 ( n = 599) challenged the generalizability of some effects related to manipulated characteristics of a news story. In contrast, correlational relationships between perceived news characteristics and news evaluation were relatively stable. In particular, participants' liking of the protagonist and the perceived likelihood of a good ending were positively associated with suspense, reading appreciation, and lingering interest. This result indicates a preference for happy endings and contradicts the notion that likely negative outcomes are beneficial for suspense and the enjoyment of news stories, as postulated by the affective-disposition theory in the context of fictional dramas. Moreover, experienced suspense reliably mediated the correlations between, on the one hand, participants' liking of the protagonist and the perceived likelihood of a good ending and, on the other hand, reading appreciation and lingering interest. The news story's personal relevance was less influential than expected. Further, we observed a large absence of

    In this paper, we investigate both the contemporaneous and the lead-lag relationships between the mass media news and the new media news of the financial news on the constitute stocks of the CSI 300. The empirical results show that: (1) there exists a strong correlation between these two types of news; (2) the granger causality direction from new media news to mass media news is increasingly obvious, while the reverse direction has a downward trend; (3) new media is playing a increasingly important role in the stock market and exhibits a trend to substitutes the mass media.

  11. Disease Risk Perception and Safety Practices: A Survey of Australian Flying Fox Rehabilitators.

    2016-02-01

    Full Text Available Interactions with flying foxes pose disease transmission risks to volunteer rehabilitators (carers who treat injured, ill, and orphaned bats. In particular, Australian bat lyssavirus (ABLV can be transmitted directly from flying foxes to humans in Australia. Personal protective equipment (PPE and rabies vaccination can be used to protect against lyssavirus infection. During May and June 2014, active Australian flying fox carers participated in an online survey (SOAR: Survey Of Australian flying fox Rehabilitators designed to gather demographic data, assess perceptions of disease risk, and explore safety practices. Responses to open-ended questions were analysed thematically. A logistic regression was performed to assess whether rehabilitators' gender, use of PPE, threat perception, and years of experience predicted variation in their odds of being bitten or scratched. Eligible responses were received from 122 rehabilitators located predominantly on the eastern coast of Australia. Eighty-four percent of respondents were female. Years of experience ranged from <1 to 30 years (median 5 years. Respondents were highly educated. All rehabilitators were vaccinated against rabies and 94% received a rabies titre check at least every two years. Sixty-three percent of carers did not perceive viruses in flying foxes as a potential threat to their health, yet 74% of carers reported using PPE when handling flying foxes. Eighty-three percent of rehabilitators had received a flying fox bite or scratch at some point during their career. Carers provide an important community service by rescuing and rehabilitating flying foxes. While rehabilitators in this study have many excellent safety practices, including a 100% vaccination rate against rabies, there is room for improvement in PPE use. We recommend 1 the establishment of an Australia-wide set of guidelines for safety when caring for bats and 2 that the responsible government agencies in Australia support

    2014-07-02

    Recently, Hepatozoon canis infection has been detected among shepherd, hunting and stray dogs in the southern part of Hungary, which is considered to be free of Rhipicephalus sanguineus sensu lato and close to the border with Croatia. The aim of this study was to acquire information on the possibility that red foxes and/or golden jackals could play a role in the appearance and spread of H. canis in Hungary. A conventional PCR was used to amplify a 666 bp long fragment of the Hepatozoon 18S rRNA gene from blood samples collected from 334 foxes shot in 231 locations in 16 counties and 15 golden jackals shot in 9 locations in two southwestern counties close to Croatia. A second PCR assay was performed in some of the samples positive by the first PCR to amplify a larger segment (approximately 1500 bp) of the 18S rRNA gene of Hepatozoon spp. for further phylogenetic analysis. Hepatozoon infection was detected in canids shot in 30 locations and 9 counties. Altogether 26 foxes (8.0%, 95% CI: 5-11%) and 9 jackals (60%, 95% CI: 33-81%) were PCR positive. Hepatozoon canis sequences were obtained from 12 foxes and 7 jackals. DNA sequences from 16 animals were 99-100% similar to H. canis from Croatian foxes or dogs while two of the sequences were 99% similar to an Italian fox. Half (13/26) of the infected red foxes and all golden jackals were shot in the two southwestern counties. This is the first report on molecular evidence of H. canis in red foxes (Vulpes vulpes) and golden jackals (Canis aureus) from Hungary, which is considered free from the tick vector of H. canis, R. sanguineus. Although no R. sanguineus sensu lato had been found on infected or non-infected wild canids, the detection of authochnous canine hepatozoonosis in Hungary might imply that the range of R. sanguineus sensu lato has reached this country.

  14. Novel Ehrlichia and Hepatozoon agents infecting the crab-eating fox (Cerdocyon thous) in southeastern Brazil.

    2013-05-01

    This study evaluated infection by vector-borne agents in 58 crab-eating fox (Cerdocyon thous L.) that were road-killed in an Atlantic rainforest reserve in the state of Espírito Santo, southeastern Brazil. Spleen, lung, or blood samples collected from the foxes were tested in the laboratory by a battery of polymerase chain reaction (PCR) assays targeting bacteria of the genera Rickettsia, Borrelia, Coxiella, Anaplasma, and Ehrlichia; and protozoa of the genera Babesia, Hepatozoon, and Leishmania. Of the targeted organisms, evidence of infection in the foxes was detected for Ehrlichia and Hepatozoon organisms only. Overall, six (10.3%) foxes were infected by an ehrlichial agent closely related to an ehrlichial agent recently detected in free-ranging Jaguars [(Panthera onca (L.)] in central-western Brazil, and to Ehrlichia ruminantium. For Hepatozoon, 28 (48.3%) foxes were infected by an agent closely related to Hepatozoon sp. Curupira 2 and H. americanum; and one (1.7%) fox was infected by an organism closely related to reptile-associated Hepatozoon agents. Finally, 11 (19.0%) foxes were found infested by Amblyomma cajennense (F.) nymphs, which were all PCR negative for the range of vector-borne agents cited above. Because the haplotypes found in free-ranging foxes are genetically closely related to pathogens of great veterinary importance, namely E. ruminantium and H. americanum, it is highly desirable to know if these novel organisms have any important role as agents of diseases in domestic animals and wildlife in Brazil.

    1982-01-01

    A bait delivery system has been developed for red foxes and skunks in Ontario, Canada. A biomarker (Tetracycline HCl) is incorporated into a meatball in a plastic bag. Deposits of tetracycline in teeth are detected microscopically with ultra-violet illumination of undecalcified sections. Baits were dropped from aircraft at the rate of 35 per km2 and accepted by 70% of foxes and 60% of skunks in the test area. Trials of various strains of inactivated vaccines are in progress.

    2013-01-01

    Red foxes (Vulpes vulpes) are the most widespread members of the order of Carnivora. Since they often live in (peri)urban areas, they are a potential reservoir of viruses that transmit from wildlife to humans or domestic animals. Here we evaluated the fecal viral microbiome of 13 red foxes by random PCR in combination with next-generation sequencing. Various novel viruses, including a parvovirus, bocavirus, adeno-associated virus, hepevirus, astroviruses, and picobirnaviruses, were identified. PMID:23616657

  17. Flying-foxes in the Australian urban environment—community attitudes and opinions

    Nina Y. Kung

    2015-12-01

    Full Text Available The urban presence of flying-foxes (pteropid bats in eastern Australia has increased in the last 20 years, putatively reflecting broader landscape change. The influx of large numbers often precipitates community angst, typically stemming from concerns about loss of social amenity, economic loss or negative health impacts from recently emerged bat-mediated zoonotic diseases such as Hendra virus and Australian bat lyssavirus. Local authorities and state wildlife authorities are increasingly asked to approve the dispersal or modification of flying-fox roosts to address expressed concerns, yet the scale of this concern within the community, and the veracity of the basis for concern are often unclear. We conducted an on-line survey to capture community attitudes and opinions on flying-foxes in the urban environment to inform management policy and decision-making. Analysis focused on awareness, concerns, and management options, and primarily compared responses from communities where flying-fox management was and was not topical at the time of the survey. While a majority of respondents indicated a moderate to high level of knowledge of both flying-foxes and Hendra virus, a substantial minority mistakenly believed that flying-foxes pose a direct infection risk to humans, suggesting miscommunication or misinformation, and the need for additional risk communication strategies. Secondly, a minority of community members indicated they were directly impacted by urban roosts, most plausibly those living in close proximity to the roost, suggesting that targeted management options are warranted. Thirdly, neither dispersal nor culling was seen as an appropriate management strategy by the majority of respondents, including those from postcodes where flying-fox management was topical. These findings usefully inform community debate and policy development and demonstrate the value of social analysis in defining the issues and options in this complex human

  18. Diversity of Flea (Siphonaptera) Parasites on Red Foxes (Vulpes vulpes) in Romania.

    Red foxes (Vulpes vulpes (L.)) are widespread across Europe, tolerant of synanthropic ecosystems, and susceptible to diseases potentially shared with humans and other animals. We describe flea fauna on red foxes in Romania, a large, ecologically diverse country, in part because fleas may serve as an indicator of the risk of spillover of vector-borne disease. We found 912 individual fleas of seven species on the 305 foxes assessed, for an infestation prevalence of 49.5%. Mean flea load per fox was 5.8 (range 0-44 fleas), and flea detections were most abundant in fall and early spring. Fleas included generalists (Ctenocephalides canis (Curtis), 32.6% of all fleas), Ct. felis (Bouché, 0.1%), and Pulex irritans L. (29.9%), the fox specialist Chaetopsylla globiceps (Taschenberg, 32.5%), mesocarnivore fleas Paraceras melis Walker (3.2%) and Ch. trichosa Kohaut (1.5%), and the small mammal flea Ctenophthalmus assimilis (Taschenberg, 0.1%), which is rarely or never reported from carnivores. There were significantly more female than male Ch. globiceps, Ct. canis, and Pu. irritans, and these three species were the most broadly distributed geographically. Diversity indices suggested reduced diversity in mountainous areas above 700 m. When compared to other flea studies on foxes in Europe, Romania had flea diversity near the median of reports, which was unexpected given Romania's high ecological diversity. Notably absent prey specialists, compared to other studies, include Archaeopsylla erinacei (Bouché) and Spilopsyllus cuniculi (Dale). Further studies of possible disease agents in fox fleas could help elucidate possible risks of vector-borne disease in foxes, domestic animals, and humans as well. © The Authors 2017.

  19. Laser ignitibility of insensitive secondary explosive 1,1-diamino-2,2-dinitroethene (FOX-7)

    Fang, Xiao; McLuckie, Warren G

    2015-01-01

    Highlights: • Carbon black (CB) is an efficient optical sensitizer compatible with 1,1-diamino-2,2-dinitroethene (FOX-7). • A CB doped insensitive explosive FOX-7 can be ignited by a low-power diode laser. • Laser ignitibility of the optically sensitized FOX-7 is mainly affected by laser power among the other parameters. • Inhomogeneities in the explosive affect laser ignition reliability. - Abstract: An experimental investigation into laser ignitibility of insensitive secondary explosives, 1,1-diamino-2,2-dinitroethene (FOX-7) has been carried out, using a diode laser of continuous wave at the laser wavelength of 974 nm. The direct optical ignition of an insensitive explosive will add more safety features to insensitive munitions (IM) or explosive devices. In this study, effects of laser parameters on the ignitibility were analysed in terms of laser ignition threshold, the times to initiate the ignition and full combustion, and burning sustainability. The results have shown that carbon black (CB) as an optical sensitizer is compatible with FOX-7, and significantly enhances laser ignitibility of the explosive when a small amount of CB is uniformly doped in FOX-7. The delay times for ignition and subsequent development of sustainable burning of the material are mainly determined by ignition laser power, although the other laser parameters have effects. The minimum laser power required to ignite the optically sensitized FOX-7 was found below 10 W and a fast ignition was initiated in as short as 70 μs by a laser power of 40 W. Also the effect of the mixture uniformity of FOX-7/CB on laser ignition performance was evaluated in this study

  20. Review of Arctic fox. Life at the top of the world, by Gary Hamilton

    2009-01-01

    The Arctic fox is the only truly Arctic species among the terrestrial carnivorous mammals of the world. It is distributed across the circumpolar Arctic region. Like polar bears, Arctic foxes regularly traverse the pack ice of the polar basin, a fact that astonished Fridtjof Nansen during his attempt to reach the North Pole more than 100 years ago. However, despite its unique lifestyle, which in some respects is more fascinating than that of the polar bear, there has been no popular book (exce...

  1. Nodal-dependent mesendoderm specification requires the combinatorial activities of FoxH1 and Eomesodermin.

    Christopher E Slagle

    2011-05-01

    Full Text Available Vertebrate mesendoderm specification requires the Nodal signaling pathway and its transcriptional effector FoxH1. However, loss of FoxH1 in several species does not reliably cause the full range of loss-of-Nodal phenotypes, indicating that Nodal signals through additional transcription factors during early development. We investigated the FoxH1-dependent and -independent roles of Nodal signaling during mesendoderm patterning using a novel recessive zebrafish FoxH1 mutation called midway, which produces a C-terminally truncated FoxH1 protein lacking the Smad-interaction domain but retaining DNA-binding capability. Using a combination of gel shift assays, Nodal overexpression experiments, and genetic epistasis analyses, we demonstrate that midway more accurately represents a complete loss of FoxH1-dependent Nodal signaling than the existing zebrafish FoxH1 mutant schmalspur. Maternal-zygotic midway mutants lack notochords, in agreement with FoxH1 loss in other organisms, but retain near wild-type expression of markers of endoderm and various nonaxial mesoderm fates, including paraxial and intermediate mesoderm and blood precursors. We found that the activity of the T-box transcription factor Eomesodermin accounts for specification of these tissues in midway embryos. Inhibition of Eomesodermin in midway mutants severely reduces the specification of these tissues and effectively phenocopies the defects seen upon complete loss of Nodal signaling. Our results indicate that the specific combinations of transcription factors available for signal transduction play critical and separable roles in determining Nodal pathway output during mesendoderm patterning. Our findings also offer novel insights into the co-evolution of the Nodal signaling pathway, the notochord specification program, and the chordate branch of the deuterostome family of animals.

    Full Text Available This paper demonstrates that digital tools provide opportunities for new storytelling techniques. To take full advantage of the new media resources and to establish an innovative news narrative structure, the existing research limit and the relationship between narrative and the media were examined. This paper progresses from a discussion on the narrative structure to how the plot of a story is influenced by its discourse, and then to how different media characteristics can change the structure and voice of the involved narrative. A new narrative structure that can be used to explore the hypertext and interactivity of Internet news is described. Finally, this paper discusses the cultivation of news storytelling in the digital age.

  3. [Breaking bad news in clinical practice].

    Herrera, Andrea; Ríos, Matías; Manríquez, José Manuel; Rojas, Gonzalo

    2014-10-01

    Breaking bad news is a complex task that requires multiple communication skills from health professionals. Clinical practice demands to communicate all type of bad news, from a diagnosis of cancer to adverse effects of a treatment. On the other hand, since the beginning of the health reform in 2003, the need to improve the quality of services was proposed, among which the concern about the rights and duties of patients stands out. Therefore, the health care provider-patient relationship becomes again the subject of discussion and study, and a topic of great importance for clinical work. We revise the consequences of breaking bad news for the patient and for the health care provider, as well as the current protocols available for this purpose. The importance of developing communication skills both for future health professionals as for those who currently work in the area is emphasized.

Where does it operate? And what are its consequences? These questions are raised in order to help identify the actions and strategies benefitting news sources, as well as the impact on journalism: the accommodation of journalists, the reduction or elimination of investigative journalism, the transference of the news to digital social networks, and the expansion of media sources. The article draws on a survey conducted with 163 news sources and journalists, on the premise that spin doctors are professional communicators, who are able to forge public opinion using processes, procedures, journalist’s co-optation, and knowledge of journalism and public relations, in order to be successful in the media, or directly with the target audience.

  8. Bad news: The influence of news coverage and Google searches on Gardasil adverse event reporting.

    Faasse, Kate; Porsius, Jarry T; Faasse, Jonathan; Martin, Leslie R

    2017-12-14

    Human papilloma virus vaccines are a safe and effective tool for reducing HPV infections that can cause cervical cancer. However, uptake of these vaccines has been suboptimal, with many people holding negative beliefs and misconceptions. Such beliefs have been linked with the experience of unpleasant side effects following medical treatment, and media coverage may heighten such concerns. The present study sought to assess the influence of news coverage (number of news articles per month) on adverse event reporting in response to Gardasil vaccination in New Zealand over a 7.5-year period, and whether the influence of news coverage was mediated by internet search activity (Google search volumes). Multiple linear regression analyses and simple mediation analyses were used, controlling for year and number of vaccinations delivered. News coverage in the previous month, and Google search volumes in the same month, were significant predictors of adverse event reporting, after accounting for vaccination rates and year. Concurrent Google search volumes partially mediated the effect of prior news coverage. The results suggest that some of the adverse events reported were not related to the vaccination itself, but to news coverage and internet search volumes, which may have contributed to public concerns about potentially unpleasant or harmful outcomes. These findings have implications for the importance of psychological and social factors in adverse event reporting, and the role of the news media in disseminating health information.

  9. When Sound Bites Become the News: a Case Study on Manufacturing News in Croatia

    2017-06-01

    Full Text Available Media environment is rapidly changing and facing a widespread crisis in journalism. It is followed by the decline of audience trust and increasing market pressures. The main goal is to win the audience’s attention, very often by creating drama and producing ‘conflict’. The news is not based on something that really happened and that is relevant, but it is more often manufactured or artificially produced. In this case study we explore the curious life cycle of a sound bite from a passing remark by the then Croatian Prime Minister Zoran Milanović’s to the headlines, discussions and extensive reports which developed over the course of several days. This example shows how news could be manufactured and content blurred when it is built around a fragment without providing the context, in this case a political quote. For several days, politicians, experts, war veterans, but also ordinary citizens were involved in the manufactured news story without making a reference to the context. Consequently, the democratic debate was avoided. Drawing on a discussion of news fragmentation as isolation from context, we show that in this case, news values (what news is are increasingly blurred, preventing the news from becoming the source of information and discussion of the country’s key issues.

    Satellite DNA is a characteristic component of mammalian centromeric heterochromatin, and a comparative analysis of its evolutionary dynamics can be used for phylogenetic studies. We analysed satellite and satellite-like DNA sequences available in NCBI for 4 species of the family Canidae (red fox, Vulpes vulpes, VVU; domestic dog, Canis familiaris, CFA; arctic fox, Vulpes lagopus, VLA; raccoon dog, Nyctereutes procyonoides procyonoides, NPR) by comparative sequence analysis, which revealed 86-90% intraspecies and 76-79% interspecies similarity. Comparative fluorescence in situ hybridisation in the red fox and dog showed signals of the red fox satellite probe in canine and vulpine autosomal centromeres, on VVUY, B chromosomes, and in the distal parts of VVU9q and VVU10p which were shown to contain nucleolus organiser regions. The CFA satellite probe stained autosomal centromeres only in the dog. The CFA satellite-like DNA did not show any significant sequence similarity with the satellite DNA of any species analysed and was localised to the centromeres of 9 canine chromosome pairs. No significant heterochromatin block was detected on the B chromosomes of the red fox. Our results show extensive heterogeneity of satellite sequences among Canidae and prove close evolutionary relationships between the red and arctic fox. © 2017 S. Karger AG, Basel.

    2015-07-01

    Extraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012. Of the cardiopulmonary nematodes, a high prevalence of Angiostrongylus vasorum and Eucoleus aerophilus (syn. Capillaria aerophila) was found, 78.2% and 41.8% respectively; Crenosoma vulpis (15.8%) and Filaroides spp. (4.8%) were also found. Spirocerca lupi (23.5%), Aonchotheca putorii (syn. Capillaria putorii) (8.6%) and Physaloptera spp. (2.5%) were detected in the stomach and Pearsonema plica (syn. Capillaria plica) (56.8%) in the bladder. Eucoleus boehmi (syn. Capillaria boehmi) was also detected in the nasal cavities of one of the two foxes examined. A coprological examination revealed eggs of E. aerophilus, A. putorii, S. lupi, Physaloptera spp. and eggs of intestinal parasites. Filarial worms were absent in all the 165 animals examined, nor was there evidence of Trichinella spp. in any of the foxes. The foxes were found to host a high prevalence of many species of extraintestinal nematodes. The prevalence of A. vasorum in foxes found in the present study is among the highest in Europe. In addition, to the best of our knowledge, E. boehmi and Filaroides spp. have never been reported before in this host in Italy.

  12. FoxM1 is a general target for proteasome inhibitors.

    Uppoor G Bhat

    2009-08-01

    Full Text Available Proteasome inhibitors are currently in the clinic or in clinical trials, but the mechanism of their anticancer activity is not completely understood. The oncogenic transcription factor FoxM1 is one of the most overexpressed genes in human tumors, while its expression is usually halted in normal non-proliferating cells. Previously, we established that thiazole antibiotics Siomycin A and thiostrepton inhibit FoxM1 and induce apoptosis in human cancer cells. Here, we report that Siomycin A and thiostrepton stabilize the expression of a variety of proteins, such as p21, Mcl-1, p53 and hdm-2 and also act as proteasome inhibitors in vitro. More importantly, we also found that well-known proteasome inhibitors such as MG115, MG132 and bortezomib inhibit FoxM1 transcriptional activity and FoxM1 expression. In addition, overexpression of FoxM1 specifically protects against bortezomib-, but not doxorubicin-induced apoptosis. These data suggest that negative regulation of FoxM1 by proteasome inhibitors is a general feature of these drugs and it may contribute to their anticancer properties.

    Angiostrongylus vasorum is the causative agent of canine angiostrongylosis, a severe snail-borne disease of dogs. Red foxes are important natural reservoirs of infection, and surveys of foxes provide a more objective picture of the parasite distribution. Our aim was to investigate the possibility of the presence of A. vasorum in red foxes from the western part of Romania and to analyse the risk factors related to the sex, age and geographic origin of the foxes. Between July 2016 and April 2017, 567 hunted red foxes from 10 counties of western Romania were examined by necropsy for the presence of lungworms. Overall, the infection with A. vasorum has been found in 24 red foxes (4.2%) originating in four counties (Mureș, Hunedoara, Sălaj and Cluj). There was no significant difference between the prevalence in males and females, between juveniles and adults and between counties. This is the first report of autochthonous infections of A. vasorum in Romania, showing a relatively low prevalence and extending eastwards the known distributional range of this parasite in Europe. The presence of autochthonous cases in domestic dogs in Romania remains to be confirmed by further studies.

  14. Breaking bad news among cancer physicians

    Sami Ayed Alshammary

    2017-01-01

    Full Text Available Background: Breaking bad news to patients with cancer diagnosis is not an easy task for physicians. The diagnosis must be explicitly stated and understood, and prognosis must be well-discussed in the most gentle and comfortable manner. It is important that the disclosure is performed in a way that patients will not lose all hope and get very depressed, leading them to undergo an abrupt change of their outlook in life. Objective: The aim of this study was to explore the physicians' perceptions and perspectives of breaking bad news to cancer patients. Methods: A cross-sectional survey of all comprehensive cancer centre physicians currently working in a university teaching hospital in the Middle East was conducted from August to September 2016. Results: Sixty-eight percent responded to the survey. Eighty-four percent were comfortable with breaking bad news, and 70% had training in breaking bad news. Eighty-six percent of responders stated that patients should be told about their cancer. Almost 30% of the respondents stated that they would still disclose the diagnosis to patients even if it would be against the preference of the relatives. Nearly 61% said that they would only tell the details to the patients if asked while 67% of them disagreed that patients should be told about the diagnoses only if the relatives consent. About 51% of physicians wanted to discuss the bad news with the family members and patient together, whereas 24% stated that the patient alone should be involved in the discussion. Conclusion: Physicians face a dilemma when families do not wish the patient to know the cancer diagnosis and this highlights the necessity of taking into consideration the social circumstances in healthcare. When taking these into considerations, curriculum in the medical school must, therefore, be updated and must integrate the acquisition of skills in breaking bad news early in training.

  15. Tipping news in information accumulation system

    Shin, J. K.

    2010-05-01

    As a continuous opinion dynamics model, the information accumulation system (IAS) includes three basic mechanisms of the news, the inheritance and the diffusion as contributing to the information accumulation process of a system. A system is composed of agents who diffuse information through internal interaction, while each of them has incomplete memory or inheritance rate. The news comes from external sources of information, such as mass media. Previously the model IAS was studied only for the small news problems. In this study, a tipping news problem is considered. A key question of the problem is: what is the minimum strength of advertisement that can tip the minority opinion to a majority one? Dynamics of the IAS is briefly revisited with a special interest on nonlinear behavior of the model. In particular, it is shown that a discrete map of the IAS for a single color problem can be transformed into a logistic map, from which the dynamics of the IAS can be better understood. To show the applicability of the IAS model, the result is applied to explain the concept of the critical population size, which claims that there is a minimum population size for a social knowledge system to be continuously inherited without being lost. And critical size of the tipping news is found analytically in terms of IAS parameters. Some of the key results from the present study are compared in detail with the results from the Brownian particle model, which is believed to be the most similar model to the IAS. The concept of tipping news is used to show that a traditional society can tip at an exceptionally low inter-community exposure. Finally, the result was applied to the language competition problem.

  16. Behavioral consequences of conflict-oriented health news coverage: the 2009 mammography guideline controversy and online information seeking.

    Weeks, Brian E; Friedenberg, Laura M; Southwell, Brian G; Slater, Jonathan S

    2012-01-01

    Building on channel complementarity theory and media-system dependency theory, this study explores the impact of conflict-oriented news coverage of health issues on information seeking online. Using Google search data as a measure of behavior, we demonstrate that controversial news coverage of the U.S. Preventive Services Task Force's November 2009 recommendations for changes in breast cancer screening guidelines strongly predicted the volume of same-day online searches for information about mammograms. We also found that this relationship did not exist 1 year prior to the coverage, during which mammography news coverage did not focus on the guideline controversy, suggesting that the controversy frame may have driven search behavior. We discuss the implications of these results for health communication scholars and practitioners.

  19. Volume, Volatility and Public News Announcements

    Bollerslev, Tim; Li, Jia; Xue, Yuan

    We provide new empirical evidence for the way in which financial markets process information. Our results are based on high-frequency intraday data along with new econometric techniques for making inference on the relationship between trading intensity and spot volatility around public news...... announcements. Consistent with the predictions derived from a theoretical model in which investors agree to disagree, our estimates for the intraday volume-volatility elasticity around the most important news announcements are systematically below unity. Our elasticity estimates also decrease significantly...

  20. Welcome to the Era of Fake News

    Jonathan Albright

    2017-06-01

    Full Text Available For the news industry, information is used to tell stories, which have traditionally been organized around “facts”. A growing problem, however, is that fact-based evidence is not relevant to a growing segment of the populace. Journalists need facts to tell stories, but they need data to understand how to engage audiences with this accurate information. The implementation of data is part of the solution to countering the erosion of trust and the decay of social discourse across networked spaces. Rather than following “trends”, news organizations should establish the groundwork to make facts “matter” by shaping the narrative instead of following deceptive statements.
