  1. Special Edition: Left Realism Today - Guest Editor’s Introduction

    Directory of Open Access Journals (Sweden)

    Walter DeKeseredy


    Full Text Available Since its birth in the mid-1980s, as a major variant of critical criminology, Left Realism continues to ebb and flow. Furthermore, not all Left realist contributions are alike and some are subject to very heated debates. The fact remains, however, that Left Realism is ‘alive and well’. Of course, given that I devoted 26 years of my life (much of it with Martin D Schwartz to the realist project, I could easily be accused of being biased. Nonetheless, some contemporary empirical support for my claim is the recent publication of Roger Matthews’ (2014 book Realist Criminology. The main objective of this volume is to use this offering as a ‘launching pad’ or ‘springboard’ for broader analyses of the relevance of Left Realism to critical criminology as we know it today. Matthews’ piece is the lead article. Following this are six others that, in part, address his monograph and that also point us to new directions in Left realist ways of knowing. In keeping with the spirit of the International Journal of Crime, Justice and Social Democracy, the authors constitute an international cadre of progressive scholars, including me, Joseph Donnermeyer, Steve Hall, Russell Hogg, John Lea, Claire Renzetti, and Simon Winlow. It cannot be emphasized enough, though, that this special issue is not a ‘love-in’ and there is no ‘party line’ here. All of the authors have strong positions on topics of major concern to academics and activists seeking new ways of thinking critically about crime, law and social control.

  3. Are Bones Alive? (United States)

    Caravita, Silvia; Falchetti, Elisabetta


    Many studies have investigated the classification of living things. Our study deals with a different problem: the attribution of life to one component of a living organism, specifically the bones. The task involves not only specifying what we mean by "alive", but also requires "informed thinking" leading to an understanding of…

  8. Radiochemistry - today

    International Nuclear Information System (INIS)

    After a longer starting period many radiation techniques have prevailed practically. Today radiation processes are usual components of chemistry, biology, medicine, and technologies in the most common sense. This paper deals with the latest state of radiation chemistry, whereas the possible practical applications are in the foreground of discussion as to reach mainly practicians in laboratory and industry. But also physicians, pharmacists and chemical engineers should be informed about the possibilities of application of high energyy radiation. Because radiation chemistry has also enriched works of related subjects, for example physical, organic and inorganic chemistry, this paper will also be of interest for experts of these disciplines.

  9. Psychoanalysis today (United States)



    The paper discusses the precarious position of psychoanalysis, a therapeutic approach which historically has defined itself by freedom from constraint and counted treatment length not in terms of number of sessions but in terms of years, in today's era of empirically validated treatments and brief structured interventions. The evidence that exists for the effectiveness of psychoanalysis as a treatment for psychological disorder is reviewed. The evidence base is significant and growing, but less than might meet criteria for an empirically based therapy. The author goes on to argue that the absence of evidence may be symptomatic of the epistemic difficulties that psychoanalysis faces in the context of 21st century psychiatry, and examines some of the philosophical problems faced by psychoanalysis as a model of the mind. Finally some changes necessary in order to ensure a future for psychoanalysis and psychoanalytic therapies within psychiatry are suggested. PMID:16946899

  14. The Status of Hitler Today

    Directory of Open Access Journals (Sweden)

    Ben Novak


    Full Text Available A finales del siglo XX, podía afirmarse que Hitler estaba más vivo y con más influencia que en la cumbre de su poder medio siglo antes. ¿Cómo ha alcanzado Hitler esta posición? ¿No está muerto? ¿Cómo puede ser tan prominente más de cincuenta años después de su defunción? Esta cuestión de Hitler en la actualidad posee diversos problemas históricos que están íntimamente conectados con otros morales. En este trabajo, sin embargo, pretendo concentrarme primordialmente en su dimensión histórica. A la luz del sorprendente ascenso de Hitler en la moderna conciencia histórica, esto puede llevarnos a la siguiente pregunta: ¿No hemos otorgado al dictador nazi un poder aún mayor que cuando estaba vivo y comandando sus divisiones de la Wehrmacht en el punto culminante de sus conquistas?___________________ABSTRACT:By the end of the twentieth century, it can be said, Hitler was more alive and prominent than at the height of his power a half-century before. How did Hitler become this way? Isn’t he dead? How can he become so prominent more than half a century after his death? The issue of Hitler today poses several historical problems that are deeply moral problems as well. In this work, however, I intend to concentrate primarily on their historical dimension. In light of Hitler’s astonishing rise in modern historical consciousness, this leads to the inevitable question: Have we not granted to Hitler a far greater power over us than ever he had when he was alive and commanding his Wehrmacht divisions at the farthest extent of his conquests?

  16. Drive alive: teen seat belt survey program. (United States)

    Burkett, Katie M; Davidson, Steve; Cotton, Carol; Barlament, James; Loftin, Laurel; Stephens, James; Dunbar, Martin; Butterfield, Ryan


    To increase teen seat belt use among drivers at a rural high school by implementing the Drive Alive Pilot Program (DAPP), a theory-driven intervention built on highway safety best practices. The first component of the program was 20 observational teen seat belt surveys conducted by volunteer students in a high school parking lot over a 38-month period before and after the month-long intervention. The survey results were published in the newspaper. The second component was the use of incentives, such as gift cards, to promote teen seat belt use. The third component involved disincentives, such as increased police patrol and school policies. The fourth component was a programmatic intervention that focused on education and media coverage of the DAPP program. Eleven pre-intervention surveys and nine post-intervention surveys were conducted before and after the intervention. The pre- and post-intervention seat belt usage showed significant differences (p<0.0001). The average pre-intervention seat belt usage rate was 51.2%, while the average post-intervention rate was 74.5%. This represents a percentage point increase of 23.3 in seat belt use after the DAPP intervention. Based on seat belt observational surveys, the DAPP was effective in increasing seat belt use among rural high school teenagers. Utilizing a theory-based program that builds on existing best practices can increase the observed seat belt usage among rural high school students.

  20. Bipolar latch with compensated keep-alive current

    Directory of Open Access Journals (Sweden)

    Dr. Hans Gustat


    Full Text Available A permanent current in addition to the main clocked current is sometimes used to increase the maximum clock rate of a bipolar latch. Although it speeds up the activation of a clocked differential stage, it deteriorates the latch function by the additional current in the inactive phase of each differential stage. Thus, a keep-alive current must be kept small with respect to the main clocked current. In this Letter, a compensation technique is shown avoiding the erroneous output of a keep-alive current. It still speeds up the activation of the main transistor pair, but results in a constant symmetric offset without affecting the differential value of the output voltage. In simulations of flip-flops and clocked comparators, this compensated keep-alive current has a much larger effect on the maximum clock rate than the uncompensated keep-alive current used so far.

    actual writing of the paper, and could be assessed as a separate task by the librarian. This would ensure that students would not write papers based on substandard sources, but on articles approved by the teachers. The information search became a separate task that was to be handed in and approved by the librarian before the students could start writing their papers. The lectures, film and tutorial were left untouched. The reference management was still peer examined and evaluated by the librarian. The difference in results was remarkable. Information searching skills, reference management skills and the overall subject skills were improved compared to the previous course. Allthough the teaching librarian and teacher noticed a remarkable difference from one semester to another, and the teacher saw remarkable change throughout the course in managing sources, the number of students in the fall 2012 were too few to actually draw any firm conclusions. In spring 2013 there are more students taking the course and it will be interesting to see how they perform.

  15. Not to declare dead someone still alive: Case reports

    Directory of Open Access Journals (Sweden)

    Anđelić Slađana


    Full Text Available Introduction. Diagnosing death represents an activity that carries a great deal of public responsibility for medical professionals and is continually exposed to the control of citizens and media. Although this is a taboo subject in medical circles, unfortunately in medical practice there are situations when the physician issues a death diagnosis form without even examining the person or for an already buried person. Such physician’s action is impermissible and it leads to the possibility of professional and criminal law punishment. Case Outline. By giving examples from practice, we wish to point out the need for exceptional caution when confirming and diagnosing death in order to diagnose the true, i.e. rule out apparent death and consequently avoid the mistake of declaring dead someone still alive. Conclusion. When confirming and declaring death, exceptional caution of the physician is necessary so as not to declare dead someone still alive!

  16. Today's markets for superconductivity

    International Nuclear Information System (INIS)



    The worldwide market for superconductive products may exceed $1 billion in 1987. These products are expanding the frontiers of science, revolutionizing the art of medical diagnosis, and developing the energy technology of the future. In general, today's customers for superconductive equipment want the highest possible performance, almost regardless of cost. The products operate within a few degrees of absolute zero, and virtually all are fabricated from niobium or niobium alloys-so far the high-temperature superconductors discovered in 1986 and 1987 have had no impact on these markets. The industry shows potential and profound societal impact, even without the new materials

  17. 'Hysteria' today and tomorrow. (United States)

    LaFrance, W Curt


    'Hysteria' (conversion disorder) remains in modern humanity and across cultures, as it has for millennia. Advances today in tools and criteria have afforded more accurate diagnosis, and advances in treatments have empowered patients and providers, resulting in a renewed interest in somatoform disorders. Future progress in understanding mechanisms may be influenced by developments in functional neuroimaging and neurophysiology. No animal model exists for somatoform symptoms or conversion disorder. Despite the absence of a known molecular mechanism, psychotherapy is helping patients with conversion disorder to take control of their symptoms and have improved quality of life, shedding light on what was once an enigma.

  18. Nuclear energy today

    International Nuclear Information System (INIS)


    Energy is the power of the world's economies, whose appetite for this commodity is increasing as the leading economies expand and developing economies grow. How to provide the energy demanded while protecting our environment and conserving natural resources is a vital question facing us today. Many parts of our society are debating how to power the future and whether nuclear energy should play a role. Nuclear energy is a complex technology with serious issues and a controversial past. Yet it also has the potential to provide considerable benefits. In pondering the future of this imposing technology, people want to know. - How safe is nuclear energy? - Is nuclear energy economically competitive? - What role can nuclear energy play in meeting greenhouse gas reduction targets? - What can be done with the radioactive waste it generates? - Does its use increase the risk of proliferation of nuclear weapons? - Are there sufficient and secure resources to permit its prolonged exploitation? - Can tomorrow's nuclear energy be better than today's? This publication provides authoritative and factual replies to these questions. Written primarily to inform policy makers, it will also serve interested members of the public, academics, journalists and industry leaders. (author)

  1. Serbian grammar today

    Directory of Open Access Journals (Sweden)

    Tanasić Sreto Z.


    Full Text Available The paper surveys research on Serbian grammar over the past fifty-odd years, approximately from the 1970s up to the present day. The paper aims at demonstrating the most relevant results of the study of Serbian grammar and at emphasising the novelties in this period. The 1970s are a time in which the study of Serbian was seen as a continuation of postwar research, and at the same time results of more recent research were being introduced to academic work, results of newer theories were being accepted, phenomena that previously did not appear in the focus of attention in Serbian scholarship were also being studied, and the research was founded on stylistically diverse corpus of the Serbian language. That was also a time of the inclusion of young academics who are still active today. New insights were given into a number of phenomena that had been topics of earlier grammatical research, but many linguistic items were also described that had been studied little or not at all. Numerous blank spots in the grammatical description of Serbian were filled in. It can be said that Serbian grammatical research in this period is on a par with the achievement of global linguistic and Slavic scholarship. All the above-mentioned leads to the conclusion that the past fifty years is a period in which great results were achieved in the grammatical research of Serbian. That facilitated the modernisation of instruments of the Standard Serbian language.

  2. Knee arthrography today

    International Nuclear Information System (INIS)

    Otto, H.; Kallenberger, R.


    The role of knee arthrography today is demonstrated and technical problems are discussed. Among a lot of variants the position of the patient and the choice of contrast media play a great part concerning the result of the examination. Mild complications occur in 0.25% of the examinations, severe and live threatening complications are extremely rare. Diagnosis of meniscal lesions is most important for knee arthrography; arthroscopy and arthrography are complementary examinations and not mutually exclusive, they achieve combined an accuracy of 97-98%. In the same way arthrography is able to evaluate the condropathy of the femoro-tibial joint, whereas accuracy of arthroscopy in the diagnosis of patellar chondropathy is much higher. There is a great reliability of arthrography regarding the evaluation of lesions of the capsule, but accuracy in lesions of the cruciate ligaments is low. Arthrography is very suitable for evaluation of Baker-cysts, since indications for almost occuring internal derangement of the knee are even available. Knee arthrography is a complex and safe procedure with very less discomfort for the patient; it has a central position in the evaluation of lesions of the knee. (orig.) [de

  5. Is Schrödinger's cat dead oa alive?

    Directory of Open Access Journals (Sweden)

    Wojciech Grygiel


    Full Text Available The Schrödinger's Cat paradox was proposed in 1935 by Edwin Schrodinger, one of the founders of quantum mechanics, as an attempt to visualize the macroscopic realization of a quantum superposition state. A cat is placed in a sealed box together with a vial of poison. A two-state particle (e.g. an electron is sent into a detector in the box resulting either in a broken or an intact vial and a dead or live cat, respectively. The main problem consists in whether the superposition state of a microscopic particle can be transferred upon the macroscopic cat, that is, whether the cat can exist in a superposition state, being simultaneously dead and alive. Since the standard Copenhagen interpretation is unable to assign any reality to the quantum superposition state, the paradox finds no resolution within the regime of this interpretation. Von Neumann's insistence on the uniform treatment of both microscopic (quantum and macroscopic (classical objects according to the laws of quantum mechanics provides a more consistent framework for the resolution of the paradox. In particular, the discovery of the phenomenon of decoherence, whereby the disappearance of the quantum interferences at the macro level is accounted for, suggests the onset of an extremely efficient interference relaxation process (10-23 s upon the interaction of the two state particle with the detector. As a result, Schrodinger's cat can exist macroscopically either as dead or alive and never as a combination of both. Decoherence not only aids the resolution of the Schrodinger's Cat paradox but also sheds light upon the mechanisms by which the macro-world emerges from the microscopic quantum realm.

  7. Left-Wing Extremism: The Current Threat

    Energy Technology Data Exchange (ETDEWEB)

    Karl A. Seger


    Left-wing extremism is ''alive and well'' both in the US and internationally. Although the current domestic terrorist threat within the U. S. is focused on right-wing extremists, left-wing extremists are also active and have several objectives. Leftist extremists also pose an espionage threat to U.S. interests. While the threat to the U.S. government from leftist extremists has decreased in the past decade, it has not disappeared. There are individuals and organizations within the U.S. who maintain the same ideology that resulted in the growth of left-wing terrorism in this country in the 1970s and 1980s. Some of the leaders from that era are still communicating from Cuba with their followers in the U.S., and new leaders and groups are emerging.

  12. Staying alive! Sensors used for monitoring cell health in bioreactors. (United States)

    O'Mara, P; Farrell, A; Bones, J; Twomey, K


    Current and next generation sensors such as pH, dissolved oxygen (dO) and temperature sensors that will help drive the use of single-use bioreactors in industry are reviewed. The current trend in bioreactor use is shifting from the traditional fixed bioreactors to the use of single-use bioreactors (SUBs). However as the shift in paradigm occurs there is now a greater need for sensor technology to play 'catch up' with the innovation of bioreactor technology. Many of the sensors still in use today rely on technology created in the 1960's such as the Clark-type dissolved oxygen sensor or glass pH electrodes. This is due to the strict requirements of sensors to monitor bioprocesses resulting in the use of traditional well understood methods, making it difficult to incorporate new sensor technology into industry. A number of advances in sensor technology have been achieved in recent years, a few of these advances and future research will also be discussed in this review. Copyright © 2017 Elsevier B.V.

    Sandrick, Karen M


    Today's lending dynamics are leading many hospitals to revisit their strategies for accessing capital: Fixed-rate bonds will likely be a centerpiece of just about any organization's capital structure going forward. Joint partnerships with physicians may provide opportunity for specific service-line strength without heavy investment in facility and equipment. Many hospitals are evaluating the sale of noncore and core assets as well as the use of ground leases or arrangements that would permit them to repurchase the assets at a later time.

  18. 'Alive' searches as complementing death searches in the epidemiological follow-up of Ontario miners

    International Nuclear Information System (INIS)

    Fair, M.E.; Newcombe, H.B.; Lalonde, P.; Poliquin, C.


    'Alive' searches have been used to complement the 'death' searches, in a study of the mortality experience of a cohort of Ontario miners. The purpose has been to develop a way of distinguishing between those cohort members who are 'confirmed' alive at a given time, and those who are 'lost to follow-up'. A total of 30,000 Workers' Compensation Board (WCB) records with valid Social Insurance Numbers (SIN) were used to search the income tax files by computer over two consecutive years (1977 and 1978) representing nearly 27 million tax returns. These tax file searches using SIN numbers have provided information on the procedures to be used in, and likely success of, the corresponding searches of the tax files that could be carried out where the SIN number is not available on the work records. The latter kind of search would have to be based on names, birth dates and such, and would be probabilistic in nature. The results of the study were as follows: After the initial death search, it was found that 7.5% of the cohort had died in Canada and their records were found on the Mortality Data Base. The remaining 92.5% has been 'assumed alive' in the earlier analysis. After the 'alive' follow-up using the income tax file, one was able to confirm that 89.1% of the 'assumed alive' had filed an income tax after the study period. Thus only 3.4% of the cohort remained untraced. Among those there could be an admixture of deaths outside of Canada, persons who have moved outside of Canada and are still alive, and/or persons alive within Canada, but who have not filed an income tax return. This study has indicated that the procedures developed are useful for purposes of 'alive' follow-up, for evaluation of the quality of the Mortality Data Base-cohort death file searches, for improving the accuracy of analytical results of epidemiological studies, and for reducing the cost and labour of resolving doubtful death searches

  19. Today's threat and tomorrow's reaction

    International Nuclear Information System (INIS)

    Moore, L.R.


    Full text: The events of September 11 have only confirmed our past nightmares and warnings to industries, agencies, and governments. The threat of even more significant catastrophic attacks, using nuclear materials, was just as real ten years ago, as it is today. In many cases, our vulnerability remains the same as years ago. There is a dire need for all organizations to agree upon threats and vulnerabilities, and to implement appropriate protections, for nuclear materials or other 'means' to achieve an event of mass destruction. All appropriate organizations (industries, agencies, and governments) should be able to define, assess, and recognize international threats and vulnerabilities in the same manner. In complimentary fashion, the organizations should be able to implement safeguards against this consistent generic threat. On an international scale the same threats, and most vulnerabilities, pose high risks to all of these organizations and societies. Indeed, in today's world, the vulnerabilities of one nation may clearly pose great risk to another nation. Once threats and vulnerabilities are consistently recognized, we can begin to approach their mitigation in a more 'universal' fashion by the application of internationally recognized and accepted security measures. The path to recognition of these security measures will require agreement on many diverse issues. However, once there is general agreement, we can then proceed to the acquisition of diverse national and international resources with which to implement the security measures 'universally' to eliminate 'weak-links' in the chain of nuclear materials, on a truly international scale. I would like to discuss: developing a internationally acceptable 'generic' statement of threat, vulnerability assessment process, and security measure; proposing this international statement of threat, vulnerability assessment process, and appropriate security measures to organizations (industries, agencies, and governments

  20. Artificial insemination in pigs today. (United States)

    Knox, R V


    Use of artificial insemination (AI) for breeding pigs has been instrumental for facilitating global improvements in fertility, genetics, labor, and herd health. The establishment of AI centers for management of boars and production of semen has allowed for selection of boars for fertility and sperm production using in vitro and in vivo measures. Today, boars can be managed for production of 20 to 40 traditional AI doses containing 2.5 to 3.0 billion motile sperm in 75 to 100 mL of extender or 40 to 60 doses with 1.5 to 2.0 billion sperm in similar or reduced volumes for use in cervical or intrauterine AI. Regardless of the sperm dose, in liquid form, extenders are designed to sustain sperm fertility for 3 to 7 days. On farm, AI is the predominant form for commercial sow breeding and relies on manual detection of estrus with sows receiving two cervical or two intrauterine inseminations of the traditional or low sperm doses on each day detected in standing estrus. New approaches for increasing rates of genetic improvement through use of AI are aimed at methods to continue to lower the number of sperm in an AI dose and reducing the number of inseminations through use of a single, fixed-time AI after ovulation induction. Both approaches allow greater selection pressure for economically important swine traits in the sires and help extend the genetic advantages through AI on to more production farms.

  1. Misconceptions Yesterday, Today, and Tomorrow. (United States)

    Leonard, Mary J; Kalinowski, Steven T; Andrews, Tessa C


    A recent essay in CBE-Life Sciences Education criticized biology education researchers' use of the term misconceptions and recommended that, in order to be up-to-date with education research, biology education researchers should use alternative terms for students' incorrect ideas in science. We counter that criticism by reviewing the continued use and the meaning of misconceptions in education research today, and describe two key debates that account for the controversy surrounding the term. We then identify and describe two areas of research that have real implications for tomorrow's biology education research and biology instruction: 1) hypotheses about the structure of student knowledge (coherent vs. fragmented) that gives rise to misconceptions; and 2) the "warming trend" that considers the effects of students' motivation, beliefs about the nature of knowledge and learning (their epistemic beliefs), and learning strategies (their cognitive and metacognitive skills) on their ability to change their misconceptions in science. We conclude with a description of proposed future work in biology education research related to misconceptions. © 2014 M. J. Leonard et al.

  2. Religious Renaissance in China Today

    Directory of Open Access Journals (Sweden)

    Richard Madsen


    Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

  3. The Coolness of Capitalism Today

    Directory of Open Access Journals (Sweden)

    Jim McGuigan


    Full Text Available This paper is about the reconciliation of cultural analysis with political economy in Marxist-inspired research on communications. It traces how these two traditions became separated with the development of a one-dimensional and consumerist cultural studies, on the one-hand, and a more classically Marxist political economy of communications, on the other hand, that was accused of holding a simplistic and erroneous concept of ideology. The paper defends a conception of ideology as distorted communication motivated by unequal power relations and sketches a multidimensional mode of cultural analysis that takes account of the moments of production, consumption and textual meaning in the circulation of communications and culture. In accordance with this framework of analysis, the cool-capitalism thesis is outlined and illustrated with reference to Apple, the ‘cool’ corporation. And, the all-purpose mobile communication device is selected as a key and urgent focus of attention for research on commodity fetishism and labour exploitation on a global scale today.

  7. Privacy in Digital Age: Dead or Alive?! Regarding the New EU Data Protection Regulations

    Directory of Open Access Journals (Sweden)

    Seyed Ebrahim Dorraji


    the critical analysis of the outstanding scientific material.Practical implications – The authors highlight the ongoing change of perception of privacy. If regulation is left behind the development of technology, privacy will hardly stay alive. On the other hand, if legislation is applied on an ex-ante basis, technological development will depend on the legislators. The balance of both may be the golden means and it basically depends on the coordinated behavior of all the stakeholders.Value – The article emphasizes that the rising role of sharp development of technology by itself does not violate privacy. It is the people using this technology and the policies they carry out that create violations (Garfinkel, 2000. In fact, threats, in the first instance, are the consequences of human behavior. In other words, technology can be a significant factor of violating or demolishing privacy, however, it may also be the major method of protecting it. The balance of both may be the key means.Research type – general review.

  10. Extension for prevention: is it relevant today? (United States)

    Osborne, J W; Summitt, J B


    Extension for prevention has been an integral part of dentistry for over 100 years. Because this concept advocated the removal of sound tooth structure, it was not totally accepted at the turn of the century. The advent of the gold casting catapulted extension for prevention into general acceptance. In 1883, Webb presented a concept of "prevention of extension of decay". This concept advocated a proximal cavity preparation extending toward the buccal and lingual aspects of the tooth so that contact with adjacent teeth would not be at the margins. The separation of the margins, along with proper restoration contours, was thought to promote natural cleansing of the embrasures with saliva and fluids in the diet. GV Black's 1891 idea of "extension for prevention" was to provide extension of the preparation to the facial and lingual line angles in order to bring about "self-cleansing" margins via food excursion. Black's concept also included extending preparations through fissures to allow cavosurface margins to be on non-fissured enamel. Black integrated the extension of the proximal margins with his concept of an occlusal isthmus for a Class II amalgam preparation one-third the faciolingual width of the occlusal surface. Challenges to this concept of extension for prevention were immediate; and, by the 1950's, narrower, more conservative preparations were seen by a few as being more effective in preserving teeth. Not only occlusal width was reassessed, but the need to routinely extend proximal margins to the buccal and lingual line angles was also questioned. By the mid-1960's and early 1970's a more conservative approach to amalgam preparation was advocated and was being taught in some dental schools. Today, a standardized outline form should not be used or taught as a principle of cavity preparation. In areas where fissure caries has necessitated a preparation extending into dentin, a composite resin or dental amalgam restoration should be placed, and a fissure

    Pedrò, Francesc


    In all OECD countries, digital media and connectedness are integral to the lives of todays learners. It is often claimed that these learners are ""new millennium learners"", or ""digital natives"", who have different expectations about education. This book contributes to the debate about the effects of technology attachment and connectedness on todays learners, and their expectations about teaching. The book sets out to answer the following questions: Can the claim that todays students are ""new millenium learners"" or ""digital natives be sustained empirically? Is there consistent research evidence demonstrating the effects of technology on cognitive development, social values, and learning expectations? What are the implications for educational policy and practice?

    Marlière Christian


    Full Text Available In this paper is presented an innovative method to map in-vivo and at nanometer scale the electrical charge distribution on membranes of alive cells. It relies on a new atomic force microscopy (AFM mode based on an electro-mechanical coupling effect. Furthermore, an additional electrical signal detected by both the deflection of the AFM cantilever and simultaneous direct current measurements was detected at low scanning rates. It was attributed to the detection of the current stemming from ionic channels. It opens a new way to directly investigate in situ biological electrical surface processes involved in bacterial adhesion, biofilm formation, microbial fuel cells, etc.

  20. MTV's "Staying Alive" global campaign promoted interpersonal communication about HIV and positive beliefs about HIV prevention. (United States)

    Geary, Cynthia Waszak; Burke, Holly McClain; Castelnau, Laure; Neupane, Shailes; Sall, Yacine Ba; Wong, Emily; Tucker, Heidi Toms


    In 2002 MTV launched a global multicomponent HIV prevention campaign, "Staying Alive," reaching over 166 countries worldwide. An evaluation of this campaign focused on three diverse sites: Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal. Data were collected before and after campaign implementation through population-based household surveys. Using linear regression techniques, our evaluation examined the effects of campaign exposure on interpersonal communication about HIV and the effects of campaign exposure and interpersonal communication on beliefs about HIV prevention. We found a consistent positive effect of exposure on interpersonal communication across all sites, though there were differences among sites with regard to whom the respondent talked about HIV. We also found a consistent positive effect of exposure on HIV prevention beliefs across sites when interpersonal communication was simultaneously entered into the model. Finally, in two sites we found a relationship between interpersonal communication and HIV prevention beliefs, controlling for exposure, though again, the effects differed by the type of person the communication was with. These similar findings in three diverse sites provide ecological validity of the findings that "Staying Alive" promoted interpersonal communication and influenced young people's beliefs about HIV prevention in a positive way, evidence for the potential of a global media campaign to have an impact on social norms.

  1. Passion in today's health care leaders. (United States)

    Piper, Llewellyn E


    Passion in today's health care leaders is essential as health care organizations face increasing demands for survival. Leaders in health care have been educated, selected, promoted, and retained based on their analytical and creativity skills. Today's health care leaders must also have emotional intelligence. Emotional intelligence is primal for passion. Emotional intelligence, which leads to passion, is crucial to the survivability of today's health care organizations. In order for health care organizations to go from good to great, the leader must inspire followers through passion. This article encourages health care leaders to gain awareness of emotional intelligence and to use emotional intelligence as part of their leadership to inspire passion. Through passion, leaders and followers become more motivated to accomplish the health care mission of serving others.

  3. Plastic debris ingested by a rough-toothed dolphin, Steno bredanensis, stranded alive in northeastern Brazil

    Directory of Open Access Journals (Sweden)

    Helen Maria Duarte do Rego Barros


    Full Text Available An adult male rough-toothed dolphin, Steno bredanensis, stranded alive on Poço da Draga Beach, Fortaleza, Ceará State, northeastern Brazil. The animal was unable to swim, was visibly emaciated, and died while being transported to the AQUASIS rehabilitation facilities. During the necropsy, two plastic bags and four pieces of sea sponges were found in the fore-stomach chamber, where the mucosa had several ulcers. The ingestion of plastic debris by dolphins is not well understood. They can eat it by mistake, since it resembles some of their prey species, or ingest it along with a prey. In Ceará State, the inappropriate disposal of solid wastes and urban effluents are major sources of pollution in the coastal zone. Urgent measures are required to minimize this threat to coastal marine mammals, such as legal mechanisms, enforcement and awareness campaigns.

  4. Different types of biotechnological wound coverages created with the application of alive human cells

    Directory of Open Access Journals (Sweden)

    Papuga A. Ye.


    Full Text Available Currently, the development and the implementation of the new biotechnological wound coverings (skin equivalents designed for temporal or permanent replacement of damaged or destroyed areas of human skin remains extremely actual relevant in clinical practice. Skin equivalents or equivalents of individual skin layers which include alive cells of different types take a special place among the artificial wound coverings. They mostly contain two basic types of cells – fibroblasts and keratinocytes (together or separately. Such bioconstructions are usually served as temporary coverings, which supply the damaged skin by biologically active substances and stimulate the regeneration of the patient's own tissues. In this review we consider as commercially available wound coverings and those which are still studied in the laboratories. Until now ideal substitutes of natural skin have not yet created, so the efforts of many researchers are focusing on the solution of this problem.

    Today, petroleum products account for 97% of the energy consumed in road transport. The purpose of replacing these products with alternative energies is to reduce oil dependence as well as greenhouse gas emissions. The high price of oil has promoted the use of 'conventional' alternative motor fuels (biofuels, LPG, NGV) and also renewed interest in syn-fuels (GTL, CTL, BTL) that have already given rise to industrial and pilot projects.

  10. [Recurrent left atrial myxoma]. (United States)

    Moreno Martínez, Francisco L; Lagomasino Hidalgo, Alvaro; Mirabal Rodríguez, Roger; López Bermúdez, Félix H; López Bernal, Omaida J


    Primary cardiac tumors are rare. Mixomas are the most common among them; 75% are located in the left atrium, 20% in the right atrium, and the rest in the ventricles. The seldom appear in atrio-ventricular valves. Recidivant mixoma are also rare, appearing in 1-5% of all patients that have undergone surgical treatment of a mixoma. In this paper we present our experience with a female patient, who 8 years after having been operated of a left atrial mixoma, began with symptoms of mild heart failure. Transthoracic echocardiography revealed recurrence of the tumor, and was therefore subjected to a second open-heart surgery from which she recovered without complications.

  11. Left atrial appendage occlusion

    Directory of Open Access Journals (Sweden)

    Ahmad Mirdamadi


    Full Text Available Left atrial appendage (LAA occlusion is a treatment strategy to prevent blood clot formation in atrial appendage. Although, LAA occlusion usually was done by catheter-based techniques, especially percutaneous trans-luminal mitral commissurotomy (PTMC, it can be done during closed and open mitral valve commissurotomy (CMVC, OMVC and mitral valve replacement (MVR too. Nowadays, PTMC is performed as an optimal management of severe mitral stenosis (MS and many patients currently are treated by PTMC instead of previous surgical methods. One of the most important contraindications of PTMC is presence of clot in LAA. So, each patient who suffers of severe MS is evaluated by Trans-Esophageal Echocardiogram to rule out thrombus in LAA before PTMC. At open heart surgery, replacement of the mitral valve was performed for 49-year-old woman. Also, left atrial appendage occlusion was done during surgery. Immediately after surgery, echocardiography demonstrates an echo imitated the presence of a thrombus in left atrial appendage area, although there was not any evidence of thrombus in pre-pump TEE. We can conclude from this case report that when we suspect of thrombus of left atrial, we should obtain exact history of previous surgery of mitral valve to avoid misdiagnosis clotted LAA, instead of obliterated LAA. Consequently, it can prevent additional evaluations and treatments such as oral anticoagulation and exclusion or postponing surgeries including PTMC.

  12. Hypoplastic left heart syndrome

    Directory of Open Access Journals (Sweden)

    Thiagarajan Ravi


    Full Text Available Abstract Hypoplastic left heart syndrome(HLHS refers to the abnormal development of the left-sided cardiac structures, resulting in obstruction to blood flow from the left ventricular outflow tract. In addition, the syndrome includes underdevelopment of the left ventricle, aorta, and aortic arch, as well as mitral atresia or stenosis. HLHS has been reported to occur in approximately 0.016 to 0.036% of all live births. Newborn infants with the condition generally are born at full term and initially appear healthy. As the arterial duct closes, the systemic perfusion becomes decreased, resulting in hypoxemia, acidosis, and shock. Usually, no heart murmur, or a non-specific heart murmur, may be detected. The second heart sound is loud and single because of aortic atresia. Often the liver is enlarged secondary to congestive heart failure. The embryologic cause of the disease, as in the case of most congenital cardiac defects, is not fully known. The most useful diagnostic modality is the echocardiogram. The syndrome can be diagnosed by fetal echocardiography between 18 and 22 weeks of gestation. Differential diagnosis includes other left-sided obstructive lesions where the systemic circulation is dependent on ductal flow (critical aortic stenosis, coarctation of the aorta, interrupted aortic arch. Children with the syndrome require surgery as neonates, as they have duct-dependent systemic circulation. Currently, there are two major modalities, primary cardiac transplantation or a series of staged functionally univentricular palliations. The treatment chosen is dependent on the preference of the institution, its experience, and also preference. Although survival following initial surgical intervention has improved significantly over the last 20 years, significant mortality and morbidity are present for both surgical strategies. As a result pediatric cardiologists continue to be challenged by discussions with families regarding initial decision

  13. Corrosion issues in nuclear industry today

    International Nuclear Information System (INIS)

    Cattant, F.; Crusset, D.; Feron, D.


    In the context of global warming, nuclear energy is a carbon-free source of power and so is a meaningful option for energy production without CO 2 emissions. Currently, there are more than 440 commercial nuclear reactors, accounting for about 15% of electric power generation in the world, and there has not been a major accident in over 20 years. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this. The re-emergence of nuclear power today is founded on the present generation of nuclear reactors meeting the demands of extended service life, ensuring the cost competitiveness of nuclear power and matching enhanced safety requirements. Nuclear power plant engineers should be able to demonstrate such integrity and reliability of their system materials and components as to enable nuclear power plants to operate beyond their initial design life. Effective waste management is another challenge for sustainable nuclear energy today; more precisely, a solution is needed for the management of high-level and long-lived intermediate-level radioactive waste over the very long term. Most nuclear countries are currently gathering the data needed to assess the feasibility of a deep geological waste repository, including the prediction of the behaviour of materials over several thousands of years. The extended service life of nuclear power plants and the need for permanent disposal for nuclear waste are today's key issues in the nuclear industry. We focus here on the major role that corrosion plays in these two factors, and on the French approaches to these two issues. (authors)

  15. Global aromatics supply. Today and tomorrow

    Energy Technology Data Exchange (ETDEWEB)

    Bender, M. [BASF SE, Ludwigshafen (Germany)


    Aromatics are the essential building blocks for some of the largest petrochemical products in today's use. To the vast majority they are consumed to produce intermediates for polymer products and, hence, contribute to our modern lifestyle. Their growth rates are expected to be in line with GDP growth in future. This contrasts the significantly lower growth rates of the primary sources for aromatics - fuel processing and steam cracking of naphtha fractions. A supply gap can be expected to open up in future for which creative solutions will be required. (orig.)

  18. Integrating a project monitoring system into a public health network: experiences from Alive & Thrive Vietnam. (United States)

    Tuan, Nguyen Thanh; Alayon, Silvia; Do, Tran Thanh; Ngan, Tran Thi; Hajeebhoy, Nemat


    Little information is available about how to build a monitoring system to measure the output of preventive nutrition interventions, such as counselling on infant and young child feeding. This paper describes the Alive & Thrive Vietnam (A&T) project experience in nesting a large-scale project monitoring system into the existing public health information system (e.g. using the system and resources), and in using monitoring data to strengthen service delivery in 15 provinces with A&T franchises. From January 2012 to April 2014, the 780 A&T franchises provided 1,700,000 counselling contacts (~3/4 by commune franchises). In commune franchises in April 2014, 80% of mothers who were pregnant or with children under two years old had been to the counselling service at least one time, and 87% of clients had been to the service earlier. Monitoring data are used to track the progress of the project, make decisions, provide background for a costing study and advocate for the integration of nutrition counselling indicators into the health information system nationwide. With careful attention to the needs of stakeholders at multiple levels, clear data quality assurance measures and strategic feedback mechanisms, it is feasible to monitor the scale-up of nutrition programmes through the existing routine health information system.

  19. Universal dynamics of complex adaptive systems: Gauge theory of things alive

    International Nuclear Information System (INIS)

    Mack, G.


    A universal dynamics of objects and their relations - a kind of ''universal chemistry'' - is discussed which satisfies general principles of locality and relativity. Einsteins theory of gravitation and the gauge theory of elementary particles are prototypes, but complex adaptive systems - anything that is alive in the widest sense - fall under the same paradigma. Frustration and gauge symmetry arise naturally in this context. Besides a nondissipative deterministic dynamics, which is thought to operate at a fundamental levle, a Thermo-Dynamics in sense of Prigogine is introduced by adding a diffusion process. It introduces irreversibility and entropy production. It equilibrates the chaotic local model of the time development (only) and is designed to be undetectable under continued observation with given finite measuring accuracy. Compositeness and the development of structure can be described in this framework. The existence of a critical equilibrium state may be postulated which is invariant under the dynamics. But it is usually not reached in a finite time from a given starting configuration, because local dynamics suffers from critical slowing down, especially in the presence of frustration. (orig.)

  20. When the dead are alive! The influence of the living dead in the letter of Jude

    Directory of Open Access Journals (Sweden)

    Stephan J. Joubert


    Full Text Available This essay investigates the impact of the deceased on  the audience to which the letter of Jude was originally addressed. A construct of the influence of the “living dead” in ancient Babylon, Israel, the Graeco-Roman world and in African tradition serves as a basic cognitive map to come to terms with Jude’s views on the dead. It is argued that, since the wicked dead, who are being physically punished in  the underworld,  are kept alive  in the collective memory of Jude’s community and since their deeds are re-enacted in the sinful behavior  of intruders in their midst, their lives are influenced by  the “presence” of these living dead. On the other hand and, although Jude does not deal with the physical whereabouts of the righteous death, he and his readers know that their postmortem honour is still intact. The righteous in this community is assured that God protects the integrity of the faithful dead.

  1. Gastric residual volume in critically ill patients: a dead marker or still alive? (United States)

    Elke, Gunnar; Felbinger, Thomas W; Heyland, Daren K


    Early enteral nutrition (EN) is consistently recommended as first-line nutrition therapy in critically ill patients since it favorably alters outcome, providing both nutrition and nonnutrition benefits. However, critically ill patients receiving mechanical ventilation are at risk for regurgitation, pulmonary aspiration, and eventually ventilator-associated pneumonia (VAP). EN may increase these risks when gastrointestinal (GI) dysfunction is present. Gastric residual volume (GRV) is considered a surrogate parameter of GI dysfunction during the progression of enteral feeding in the early phase of critical illness and beyond. By monitoring GRV, clinicians may detect patients with delayed gastric emptying earlier and intervene with strategies that minimize or prevent VAP as one of the major risks of EN. The value of periodic GRV measurements with regard to risk reduction of VAP incidence has frequently been questioned in the past years. Increasing the GRV threshold before interrupting gastric feeding results in marginal increases in EN delivery. More recently, a large randomized clinical trial revealed that abandoning GRV monitoring did not negatively affect clinical outcomes (including VAP) in mechanically ventilated patients. The results have revived the discussion on the role of GRV monitoring in critically ill, mechanically ventilated patients receiving early EN. This review summarizes the most recent clinical evidence on the use of GRV monitoring in critically ill patients. Based on the clinical evidence, it discusses the pros and cons and further addresses whether GRV is a dead marker or still alive for the nutrition management of critically ill patients. © 2014 American Society for Parenteral and Enteral Nutrition.

  2. Sustainability by Education: How Latvian Heritage was Kept Alive in German Exile

    Directory of Open Access Journals (Sweden)

    Franzenburg Geert


    Full Text Available Sustainability is one of the core challenges for education in modern times, particularly concerning cultural heritage. The study evaluates, from a German point of view, how Latvians outside of Latvia after World War II kept their cultural heritage alive by educational concepts, which can be characterized as early roots of modern sustainable education. The evaluation focus concerns a group of Latvians in Germany associated with the Latvian high school in Muenster (MLG. The study concerns the 25 years from 1957 (school relocation to Muenster until 1982 (founding of the organization “Latvian Center of Muenster e.V.” (LCM, and combines interviews and literature research. It underlines that environmental, social and heritage education can be seen as core elements of Latvian education abroad. Therefore, the study will not present a concise history of the Latvian high school in Muenster (MLG, which has already been done (Sprogis, 2009, but will concisely evaluate the educational concepts of this particular period as a model, how Latvians maintained their heritage in a sustainable way.

  3. Lipids, hemoproteins and carotenoids in alive Rhodotorula mucilaginosa cells under pesticide decomposition - Raman imaging study. (United States)

    Pacia, Marta Z; Pukalski, Jan; Turnau, Katarzyna; Baranska, Malgorzata; Kaczor, Agnieszka


    Various species of yeasts are gaining attention as producers of nutraceuticals and biofuels and due to their capacity to biodegrade chemical waste. Rhodotorula mucilaginosa is one of the most oleaginous species of yeast, an efficient de novo carotenoid producer and was reported to be capable of decomposing of organic pesticides. In this work we studied the influence of a toxic pesticide, diazinone, on production of storage (lipids) and protective (carotenoids, hemoproteins) compounds by Rh. mucilaginosa alive cells with the help of Raman imaging. It occurred that the yeast in non-oleaginous phase and aerobic environment was rich in carotenoids and their level increased significantly under incubation with diazinone, while anaerobic environment resulted in production of both carotenoids and hemoproteins and the level of the latter decreased under the influence of the pesticide. For yeasts in oleaginous phase, it was concluded that lipid production (via triggering of NAD + accumulation and increase of the NO level) resulted in nitrosative stress leading to flavohemoprotein synthesis and was associated with the increase of the mitochondrial activity.

  5. Information surety for today and tomorrow

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, S.K.


    Information Surety is the enhancement of the confidentiality, integrity, and availability of information and software systems. It is attained through sequential steps: identification of software reliability requirements and information protection needs, designing for a balanced level of risk throughout the system, and application of appropriate software and hardware technologies and procedures. The ability to apply these steps when developing systems is impaired by a general lack of understanding of surety issues by system developers, and by the fact that there are many separate areas of knowledge involved that are not currently integrated into a disciplined approach (e.g., risk assessment, information access control in computers and networks, secure messaging, trusted software development). Our best systems today are achieved by clever designers who use ad-hoc methods. In the absence of good development tools, technologies may be applied haphazardly and/or retrofitted, without yielding balanced protection. This paper will take the audience through an exploration of the elements of information surety, some common misconceptions about information surety today, and the even greater challenges on the horizon. It will end with some suggestions for research areas which will help evolve the discipline of information surety.

    Sheila M. Bird


    Full Text Available The prison-based N-ALIVE pilot trial had undertaken to notify the Research Ethics Committee and participants if we had reason to believe that the N-ALIVE pilot trial would not proceed to the main trial. In this paper, we describe how external data for the third year of before/after evaluation from Scotland's National Naloxone Programme, a related public health policy, were anticipated by eliciting prior opinion about the Scottish results in the month prior to their release as official statistics. We summarise how deliberations by the N-ALIVE Trial Steering-Data Monitoring Committee (TS-DMC on N-ALIVE's own interim data, together with those on naloxone-on-release (NOR from Scotland, led to the decision to cease randomization in the N-ALIVE pilot trial and recommend to local Principal Investigators that NOR be offered to already-randomized prisoners who had not yet been released.

  9. Radioactive waste management: yesterday, today and tomorrow

    International Nuclear Information System (INIS)

    Prince, A.T.


    The public believes that there is a radioactive waste problem, but knowledge in the field is so well advanced that the only problem left is how to choose the most economically effective method among many available. Tailings from uranium ore processing could be made harmless by removing the majority of the radium and storing the remaining waste in well-designed retention areas. Non-fuel reactor wastes may be handled by incineraton, reverse osmosis, and evaporation in a central waste management centre. The dry storage of spent fuel in concrete cannisters is being investigated. Ultimate disposal of high-level wastes will be in deep, stable geologic formations. (LL)

  10. Power generation today - responsibility for the environment

    International Nuclear Information System (INIS)

    In the years following the war, the electric power utilities built up a reliable and economic energy supply with the mandate of the people, thereby also taking the environment into account in the technical development of the power stations. Due to the change in public opinion after the build-up phase, environmental protection was brought to the forefront of the public debate. Today, roles must be reassigned in the division of labour between politics and industry, tried and tested during many years. It is politics' task to dictate the long-term and calculable goals of environmental policy while taking into account their effect on the economy. With this as a basis, the individual companies must then be allowed to develop their own sense of responsibility for environmental protection. In addition to this, environmental protection needs to be accorded a permanent position in strategic and operational corporate planning. (orig./UA) [de

  11. ETI, SETI and today's public opinion (United States)

    Pinotti, Roberto

    During the last three decades the general public's initial opinions about ETI and SETI changed, turning ignorance, fear and superficiality into a gradual understanding of the importance of these concepts. After a brief analysis of this changing psycho-sociological attitude, the paper provides an "estimate of the situation" about general interest for ETI and SETI, suggesting a growing awareness in today's public opinion. Science fiction movies like Close Encounters of the Third Kind and E.T. the Extra-Terrestrial and popular interest in UFOs as visitors from outer space played a major role in the average man's acceptance of the reality of extra-terrestrial life and its meaning for mankind.

  14. "Stayin' alive": a novel mental metronome to maintain compression rates in simulated cardiac arrests. (United States)

    Hafner, John W; Sturgell, Jeremy L; Matlock, David L; Bockewitz, Elizabeth G; Barker, Lisa T


    A novel and yet untested memory aid has anecdotally been proposed for aiding practitioners in complying with American Heart Association (AHA) cardiopulmonary resuscitation (CPR) compression rate guidelines (at least 100 compressions per minute). This study investigates how subjects using this memory aid adhered to current CPR guidelines in the short and long term. A prospective observational study was conducted with medical providers certified in 2005 AHA guideline CPR. Subjects were randomly paired and alternated administering CPR compressions on a mannequin during a standardized cardiac arrest scenario. While performing compressions, subjects listened to a digital recording of the Bee Gees song "Stayin' Alive," and were asked to time compressions to the musical beat. After at least 5 weeks, the participants were retested without directly listening to the recorded music. Attitudinal views were gathered using a post-session questionnaire. Fifteen subjects (mean age 29.3 years, 66.7% resident physicians and 80% male) were enrolled. The mean compression rate during the primary assessment (with music) was 109.1, and during the secondary assessment (without music) the rate was 113.2. Mean CPR compression rates did not vary by training level, CPR experience, or time to secondary assessment. Subjects felt that utilizing the music improved their ability to provide CPR and they felt more confident in performing CPR. Medical providers trained to use a novel musical memory aid effectively maintained AHA guideline CPR compression rates initially and in long-term follow-up. Subjects felt that the aid improved their technical abilities and confidence in providing CPR. Copyright © 2012. Published by Elsevier Inc.

  18. Field primatology of today: current ethical issues. (United States)

    MacKinnon, K C; Riley, E P


    As members of professional organizations such as American Society of Primatologists (ASP) and the International Primatological Society (IPS), primatologists must adhere to a set of nonhuman primate-focused principles outlined in resolutions and policy statements on, for example, the ethical treatment of nonhuman primates. Those of us that work in the field must also address issues such as the protection of primate health in the wild and the conservation of wild primate populations. Moreover, we increasingly find ourselves in complex situations where we must balance human and nonhuman primate needs and interests. The selection of commentary pieces in this edition of the American Journal of Primatology originated from presentations given in the symposium, Field Primatology of Today: Navigating the Ethical Landscape, held at the 32nd Annual Meeting of the American Society of Primatologists (ASP) in September 2009. The goals of that symposium and these resulting commentary pieces are threefold: (1) to revive a discussion of key contemporary ethical issues faced by field primatologists, (2) to highlight the need for centrally placed ethical considerations in various facets of our professional lives, particularly research and teaching, and (3) to consider what a comprehensive ethical code that addresses all of these issues might look like.

  19. Academic dishonesty today, unethical practices tomorrow? (United States)

    LaDuke, Rebekah D


    The purpose of this article was to review the most current published literature on the topics of academic dishonesty, unethical professional practices, and research that studied the correlation between these 2 areas of interest. Literature was retrieved by utilizing key words such as academic dishonesty, cheating, workplace dishonesty, and unethical behavior. Multiple research databases were used and a reference librarian in locating relevant research studies resulting in 16 research articles reviewed and 7 articles referenced within the literature review. Upon completion, it became apparent that nursing educators should be concerned that nursing students found to be academically dishonest today may have a higher incidence of displaying unethical practices as a registered nurse tomorrow. It also became clear that the nursing profession needs to conduct its own research in this field to verify findings discovered by other professions such as engineering, business, and psychology. Finally, recommendations were given on how nursing educators should handle the topic of ethics in nursing programs. Copyright © 2013 Elsevier Inc. All rights reserved.

  20. Today's Food System: How Healthy Is It? (United States)

    Wallinga, David


    With its focus on the quantity of production, often to the exclusion of other goals, today's food system is on an unsustainable course. The problem begins with and is driven by industrialized production of both crops and animals. Industrialization is a product of technological change, public policy, and, most recently, globalized trade. The lack of sustainability derives from reliance on the intensive use of nonrenewable and hard-to-renew resources-soil, antibiotics, fresh water, and fossil fuels, for example-but also from the waste and pollution created by the industrial model. For at least 50 years, American agriculture policies have promoted production of, and ultimately lower market prices for, commodity crops like corn, wheat, and soybeans. Over the last 3 decades in particular, these "cheap food" policies have exacerbated the negative impacts of an industrialized agriculture on the health of the agro-ecosystem, as well as on the health of the humans who must share and be sustained by it. Sustainability and health are two sides of the same food system coin. Policies that put US food production on more sustainable footing can help aid in public efforts to address the myriad crises confronting both the food and health systems.

  1. Ultrasound physical principles in today's technology. (United States)

    Starkoff, Brian


    Introduction : New technology options are being provided on modern ultrasound machines such as tissue harmonic imaging, panoramic imaging, encoded pulses, mechanical and matrix 4D ultrasound and elastography. The increase in available features requires enhanced knowledge of the clinical benefits associated with each feature and of the additional diagnostic information in the images. However the question arises as to the necessity of understanding how these new technologies work. Also, ultrasound machines have become much more automated in recent years, with designers making it easier for users to produce excellent quality images with minimal technical input. Discussion : System presets provide adjustments to a variety of basic settings without the user requiring the knowledge of what each setting is doing. The developments in machine design and the increased level of automation pose an interesting question for sonologists and sonographers: Is there a need to know as much about the physical principles of ultrasound today as was required in the past? Conclusion : To answer this question, this article will look at just one recent advance in ultrasound - Tissue Harmonic Imaging. The various mechanisms of this technology will be discussed with reference to the underlying principles of basic ultrasound physics. The conclusion provided is that a good grounding in the physics of ultrasound remains of vital importance in understanding new technologies and enabling informed decisions to be made on their use.

  2. Introduction: The Continued Importance of Smallholders Today

    Directory of Open Access Journals (Sweden)

    Jacqueline M. Vadjunec


    Full Text Available Smallholders remain an important part of human-environment research, particularly in cultural and political ecology, peasant and development studies, and increasingly in land system and sustainability science. This introduction to the edited volume explores land use and livelihood issues among smallholders, in several disciplinary and subfield traditions. Specifically, we provide a short history of smallholder livelihood research in the human-environment tradition. We reflect on why, in an age of rapid globalization, smallholder land use and livelihoods still matter, both for land system science and as a reflection of concerns with inequality and poverty. Key themes that emerge from the papers in this volume include the importance of smallholder farming and land-use practices to questions of environmental sustainability, the dynamic reality of smallholder livelihoods, the challenges of vulnerability and adaptation in contemporary human-environment systems, and the structural and relative nature of the term “smallholder.” Overall these contributions show that smallholder studies are more pertinent than ever, especially in the face of global environmental change. Additionally, we argue that questions of smallholder identity, social difference, and teleconnections provide fertile areas of future research. We conclude that we need to re-envision who the smallholder is today and how this translates into modern human-environment smallholder studies.

    Full Text Available Ancient Azerbaijanian music was found after archelogical excavations. In the first literature The Book of Dede Korkut, then in Nizami's and Fuzuli's literal works a vast of information could be found about the Medieval Age music. The first phase of Azerbaijanian musical history contains arts of bards, laters phases contains classical modes. The researches of Azerbaijanian modes extend to the Medieval Age. The expand of 19th century European music affected Azerbaijanian culture, too. The early years of 20th century is reckoned as a new rising period in Azerbaijanin music. Uzeyir Hacibeyov composed Leyli and Majnun in that period which was the first opera of the East. Meanwhile, several musical high schools, conservatories, symphony orchestras, national instrumental orchestras, and theatres were established. The smphonic music which was established in 1920's had a major development in between 1940 and 1960. In between 1960 and 1980, younger generation, too, participated in artistic activities, alongside the older generation. In 1988-1994 Armenians invaded Karabagh and commited several genocides which some of the most known are called 20 January and Khojaly genocides. In that period, Azerbaijanian composes divided into three stages as 20 January, Karabagh, and Khojaly. Today, Azerbaijanian music is well known all over the world, while being played in lots of festivals in the whole world.

    Full Text Available As in the other Scandinavian countries, so in Finland an exceptionally high percentage of the population belongs to a religious community. Today, about 82 per cent of Finns are members of the Evangelical Lutheran Church. However, the picture of the Finnish religious and spiritual landscape is more complex than it may at first appear. The project ‘Religions in Finland’ was started in 2003. The project is a joint-effort of the Church Research Institute and the Research Network for the Study of New Religious Movements. The aim is to create an electronic database for describing, mapping and analysing religious associations and communities in Finland (active ones and also those that no longer exist. In August 2007 there were 777 communities and organizations listed in the database. They are classified into ten categories representing religious traditions according to their historical and cultural background. There are 29 organizations classified under the category Western esotericism. This article presents a general overview of the major and recently founded esoteric groups in Finland, most of which are registered associations.

  6. RTP as an Optional Service: It's Alive, But Is It Well?

    Energy Technology Data Exchange (ETDEWEB)

    Goldman, Charles; Barbose, Galen; Neenan, Bernie


    Economists have advocated for real-time pricing (RTP) of electricity on the basis of the gains in economic efficiency that would result from charging customers the contemporaneous marginal cost of supplying electricity instead of the average cost. In recent years, RTP has also become the subject of interest in a variety of policy contexts, including integrated resource planning initiatives, ongoing efforts to improve efficiency and reliability in competitive electricity markets, and implementation of default service in states with retail choice. Most experience with RTP has been as an optional service, that is, a self-selecting alternative to the standard utility service. By our count, approximately 70 utilities in the U.S. offered an optional RTP program at some point over the past 20 years. However, many programs are now defunct. In 2003, 47 utilities in the U.S. were still offering an optional RTP program, on either a pilot or permanent basis (see Figure 1). In addition, 10 utilities in states with retail choice currently offer RTP as the default service for large customers that are not under contract with a competitive supplier. Another two utilities have received regulatory approval to do so in the next few years. Although the results of a few optional RTP programs have been publicized, the vast majority of programs have operated in relative obscurity. To provide a wider perspective on utility and customer experience with RTP, we surveyed 43 optional RTP programs offered in 2003. We interviewed RTP program managers and other utility staff, and reviewed publicly available sources, including key regulatory documents and program evaluations. Based on this research, we identified trends related to RTP program history and outlook, program design and implementation, customer participation, and participant price response. The results are both surprising and instructive. We conclude that RTP is indeed alive but is not prospering as well it could. Thus, we offer a

    Block, Gladys; Azar, Kristen Mj; Block, Torin J; Romanelli, Robert J; Carpenter, Heather; Hopkins, Donald; Palaniappan, Latha; Block, Clifford H


    In the United States, 86 million adults have pre-diabetes. Evidence-based interventions that are both cost effective and widely scalable are needed to prevent diabetes. Our goal was to develop a fully automated diabetes prevention program and determine its effectiveness in a randomized controlled trial. Subjects with verified pre-diabetes were recruited to participate in a trial of the effectiveness of Alive-PD, a newly developed, 1-year, fully automated behavior change program delivered by email and Web. The program involves weekly tailored goal-setting, team-based and individual challenges, gamification, and other opportunities for interaction. An accompanying mobile phone app supports goal-setting and activity planning. For the trial, participants were randomized by computer algorithm to start the program immediately or after a 6-month delay. The primary outcome measures are change in HbA1c and fasting glucose from baseline to 6 months. The secondary outcome measures are change in HbA1c, glucose, lipids, body mass index (BMI), weight, waist circumference, and blood pressure at 3, 6, 9, and 12 months. Randomization and delivery of the intervention are independent of clinic staff, who are blinded to treatment assignment. Outcomes will be evaluated for the intention-to-treat and per-protocol populations. A total of 340 subjects with pre-diabetes were randomized to the intervention (n=164) or delayed-entry control group (n=176). Baseline characteristics were as follows: mean age 55 (SD 8.9); mean BMI 31.1 (SD 4.3); male 68.5%; mean fasting glucose 109.9 (SD 8.4) mg/dL; and mean HbA1c 5.6 (SD 0.3)%. Data collection and analysis are in progress. We hypothesize that participants in the intervention group will achieve statistically significant reductions in fasting glucose and HbA1c as compared to the control group at 6 months post baseline. The randomized trial will provide rigorous evidence regarding the efficacy of this Web- and Internet-based program in reducing or

  8. Why Dora Left

    DEFF Research Database (Denmark)

    Gammelgård, Judy


    The question of why Dora left her treatment before it was brought to a satisfactory end and the equally important question of why Freud chose to publish this problematic and fragmentary story have both been dealt with at great length by Freud’s successors. Dora has been read by analysts, literary...... critics, and not least by feminists. The aim of this paper is to point out the position Freud took toward his patient. Dora stands out as the one case among Freud’s 5 great case stories that has a female protagonist, and reading the case it becomes clear that Freud stumbled because of an unresolved...... problem toward femininity, both Dora’s and his own. In Dora, it is argued, Freud took a new stance toward the object of his investigation, speaking from the position of the master. Freud presents himself as the one who knows, in great contrast to the position he takes when unraveling the dream. Here he...

    CERN Multimedia


    The Prevessin Control Room during LEP's start up in 1989. The Prévessin Control Room (PCR) was recently engulfed in a wave of nostalgia. The PCR, scene of some of the greatest moments in CERN's history, is being dismantled to prepare for a complete overhaul. In February 2006, a new combined control centre for all the accelerators will open its doors on the same site, together with a new building currently under construction (see Bulletin issue 27/2004 of 28 June 2004). This marks the end of an important chapter in CERN's history. The Prévessin Control Room saw its first momentous event 28 years ago when the 400 GeV beam for the SPS was commissioned in the presence of Project Leader John Adams. It was also here that the first proton-antiproton collisions were observed, in 1981. Eight years later, in 1989, operators and directors alike jumped for joy at the announcement of the first electron-positron collisions at the start up of LEP, the biggest accelerator in the world. Today the 80 terminals and PCs have b...

  10. "What Today's University Students Have Taught Us”

    Directory of Open Access Journals (Sweden)

    Alison J. Head


    Full Text Available Today, more students in the US are attending university than ever before. An unprecedented number of these students were born digital—meaning digital technologies have been a constant feature in their lives. For these young adults, information literacy competencies are always being formed, practiced, and learned. Project Information Literacy (PIL is a series of ongoing quantitative and qualitative research studies in the US that investigates what it is like to be a university student in the digital age. This research study has investigated how students find information and conduct research—in their words and through their experiences—for coursework, use in their everyday lives, and, once they graduate, in the workplace and their communities. Since 2008, more than 11,000 university students at nearly 60 US higher education institutions have been surveyed or interviewed, making PIL the largest study of information literacy ever conducted. Results from PIL’s studies have concluded students’ information competencies are put to the test in the vast information landscape they inhabit. Furthermore, finding and using information is exponentially more complex than it was a generation ago, especially since the information landscape has shifted from one of scarce resources to one of overload. In this keynote, five research takeaways were presented from PIL’s eight studies: (1 Students find research more difficult than ever before, (2 getting started is the hardest part of research, (3 frustrations begin with finding context, i.e., big picture, information-gathering, language, and situational context, (4 search strategies are based on predictability, familiarity, and efficiency, and (5 evaluation is the one information skills most learn to use. Discussion included implications of these findings for teaching, learning, work, and librarianship in the 21st century.

  11. Fixing health care from the inside, today. (United States)

    Spear, Steven J


    Today, you are about as safe in a U.S. hospital as you would be parachuting off a bridge or a building. But it doesn't have to be that way. Right now, some hospitals are making enormous short-term improvements, with no legislation or market reconfiguration and little or no capital investment. Instead of waiting for sweeping changes in market mechanisms, these institutions are taking an operations approach to patient care. In case after detailed case, the article describes how doctors, nurses, technicians, and managers are radically increasing the effectiveness of patient care and dramatically lowering its cost by applying the same capabilities in operations design and improvement that drive the famous Toyota Production System. They are removing ambiguity in the output, responsibilities, connections, and methods of their work processes. These changes-which can be done in the course of an ordinary workday, sometimes in a matter of hours-are designed to make the following crystal clear: Which patient gets which procedure (output); Who does which aspect of the job (responsibility); Exactly which signals are used to indicate that the work should begin (connection); and Precisely how each step is carried out (method). Equally important, managers are being transformed from rescuers who arrive with ready-made solutions into problem solvers who help colleagues learn the experimental method. Thus, these hospitals are breaking free of the work-around culture that routinely obscures the root causes of so many problems, creates so much waste, and leads to so many unnecessary deaths.

  12. Ancient water supports today's energy needs (United States)

    D'Odorico, Paolo; Natyzak, Jennifer L.; Castner, Elizabeth A.; Davis, Kyle F.; Emery, Kyle A.; Gephart, Jessica A.; Leach, Allison M.; Pace, Michael L.; Galloway, James N.


    The water footprint for fossil fuels typically accounts for water utilized in mining and fuel processing, whereas the water footprint of biofuels assesses the agricultural water used by crops through their lifetime. Fossil fuels have an additional water footprint that is not easily accounted for: ancient water that was used by plants millions of years ago, before they were transformed into fossil fuel. How much water is mankind using from the past to sustain current energy needs? We evaluate the link between ancient water virtually embodied in fossil fuels to current global energy demands by determining the water demand required to replace fossil fuels with biomass produced with water from the present. Using equal energy units of wood, bioethanol, and biodiesel to replace coal, natural gas, and crude oil, respectively, the resulting water demand is 7.39 × 1013 m3 y-1, approximately the same as the total annual evaporation from all land masses and transpiration from all terrestrial vegetation. Thus, there are strong hydrologic constraints to a reliance on biofuel energy produced with water from the present because the conversion from fossil fuels to biofuels would have a disproportionate and unsustainable impact on the modern water. By using fossil fuels to meet today's energy needs, we are virtually using water from a geological past. The water cycle is insufficient to sustain the production of the fuel presently consumed by human societies. Thus, non-fuel-based renewable energy sources are needed to decrease mankind's reliance on fossil fuel energy without placing an overwhelming pressure on global freshwater resources.

  13. Using Self-Organizing Neural Network Map Combined with Ward's Clustering Algorithm for Visualization of Students' Cognitive Structural Models about Aliveness Concept. (United States)

    Yorek, Nurettin; Ugulu, Ilker; Aydin, Halil


    We propose an approach to clustering and visualization of students' cognitive structural models. We use the self-organizing map (SOM) combined with Ward's clustering to conduct cluster analysis. In the study carried out on 100 subjects, a conceptual understanding test consisting of open-ended questions was used as a data collection tool. The results of analyses indicated that students constructed the aliveness concept by associating it predominantly with human. Motion appeared as the most frequently associated term with the aliveness concept. The results suggest that the aliveness concept has been constructed using anthropocentric and animistic cognitive structures. In the next step, we used the data obtained from the conceptual understanding test for training the SOM. Consequently, we propose a visualization method about cognitive structure of the aliveness concept.

  14. Understanding phototropism: from Darwin to today. (United States)

    Holland, Jennifer J; Roberts, Diana; Liscum, Emmanuel


    Few individuals have had the lasting impact on such a breadth of science as Charles Darwin. While his writings about time aboard the HMS Beagle, his study of the Galapagos islands (geology, fauna, and flora), and his theories on evolution are well known, less appreciated are his studies on plant growth responses to a variety of environmental stimuli. In fact, Darwin, together with the help of his botanist son Francis, left us an entire book, 'The power of movements in plants', describing his many, varied, and insightful observations on this topic. Darwin's findings have provided an impetus for an entire field of study, the study of plant tropic responses, or differential growth (curvature) of plant organs in response to directional stimuli. One tropic response that has received a great deal of attention is the phototropic response, or curvature response to directional light. This review summarizes many of the most significant advancements that have been made in our understanding of this response and place these recent findings in the context of Darwin's initial observations.

  15. Non-compact left ventricle/hypertrabeculated left ventricle

    International Nuclear Information System (INIS)

    Restrepo, Gustavo; Castano, Rafael; Marmol, Alejandro


    Non-compact left ventricle/hypertrabeculated left ventricle is a myocardiopatie produced by an arrest of the normal left ventricular compaction process during the early embryogenesis. It is associated to cardiac anomalies (congenital cardiopaties) as well as to extracardial conditions (neurological, facial, hematologic, cutaneous, skeletal and endocrinological anomalies). This entity is frequently unnoticed, being diagnosed only in centers with great experience in the diagnosis and treatment of myocardiopathies. Many cases of non-compact left ventricle have been initially misdiagnosed as hypertrophic myocardiopatie, endocardial fibroelastosis, dilated cardiomyopatie, restrictive cardiomyopathy and endocardial fibrosis. It is reported the case of a 74 years old man with a history of chronic arterial hypertension and diabetes mellitus, prechordial chest pain and mild dyspnoea. An echocardiogram showed signs of non-compact left ventricle with prominent trabeculations and deep inter-trabecular recesses involving left ventricular apical segment and extending to the lateral and inferior walls. Literature on this topic is reviewed

    Arash Khamooshian


    Full Text Available During standard transesophageal echocardiographic examinations in sinus rhythm (SR patients, the left atrial appendage (LAA is not routinely assessed with Doppler. Despite having a SR, it is still possible to have irregular activity in the LAA. This situation is even more important for SR patients where assessment of the left atrium is often foregone. We describe a case where we encountered this situation and briefly review how to assess the left atrium and its appendage in such a case scenario.

  17. [Left-handedness and health]. (United States)

    Milenković, Sanja; Belojević, Goran; Kocijancić, Radojka


    Hand dominance is defined as a proneness to use one hand rather than another in performing the majority of activities and this is the most obvious example of cerebral lateralization and an exclusive human characteristic. Left-handed people comprise 6-14% of the total population, while in Serbia, this percentage is 5-10%, moving from undeveloped to developed environments, where a socio-cultural pressure is less present. There is no agreement between investigators who in fact may be considered a left-handed person, about the percentage of left-handers in the population and about the etiology of left-handedness. In the scientific literature left-handedness has been related to health disorders (spine deformities, immunological disorders, migraine, neurosis, depressive psychosis, schizophrenia, insomnia, homosexuality, diabetes mellitus, arterial hypertension, sleep apnea, enuresis nocturna and Down Syndrome), developmental disorders (autism, dislexia and sttutering) and traumatism. The most reliable scientific evidences have been published about the relationship between left-handedness and spinal deformities in school children in puberty and with traumatism in general population. The controversy of other results in up-to-now investigations of health aspects of left-handedness may partly be explained by a scientific disagreement whether writing with the left hand is a sufficient criterium for left-handedness, or is it necessary to investigate other parameters for laterality assessment. Explanation of health aspects of left-handedness is dominantly based on Geschwind-Galaburda model about "anomalous" cerebral domination, as a consequence of hormonal disbalance.

  19. International space Launch Services Today, ILS (United States)

    Rymarcsuk, James A.; Haase, Ethan E.


    In the last five years the international space launch industry has undergone substantial change. New entrants and existing players in this market have introduced new and upgraded vehicles with greater lift capability than was available five years ago. In addition, some of these vehicles offer reduced risk from their predecessors thanks to design improvements and reductions in the number of failure points. The entry of these vehicles have generated greater supply, increased choice, and improved capabilities to the benefit of satellite operators and manufacturers. Some launch service providers have also enhanced the products and services they offer due to the increased competitiveness in the market. Although the number of commercial satellites launched per year has remained within a fairly narrow range in the last five years, expectations for the future that were once very optimistic have fallen dramatically. The significant number of commercial NGSO satellites launched in the late 1990s helped raise these expectations, but today, the predicted continued growth in launches due to NGSO and broadband systems has not materialized. Despite the decline in expectations from the late 1990s, however, the satellite market that the launch industry supports remains robust. Satellite operators maintain generally favorable financial positions, but the number of satellites required to provide services worldwide is growing slowly, with the number of new and replacement satellites launched per year remaining essentially flat. Satellite operators are undergoing consolidation that is rendering them stronger than ever, and putting them in a position to demand better service from their launch service providers. The increase in supply in the marketplace and the corresponding lack of growth in demand has led to a highly competitive marketplace for launch services internationally. ILS is well positioned with products and services to meet customer needs. Key customer buying factors include

  3. Deterrence Today Roles, Challenges and Responses

    International Nuclear Information System (INIS)

    Dunn, L.A.


    deterrence in reassuring traditional allies confronting new hostile proliferators. In practice, however, extending deterrence in response to proliferation threats raises a number of difficult questions and will require adaptation of traditional approaches. But in other situations, what role, if any, deterrence - though not necessarily nuclear deterrence - should play is itself an open question. This applies perhaps most to possible efforts by the United States and other countries to bring to bear deterrence or other complementary strategies aimed at shaping a terrorist adversary's strategic calculus to help meet the threat of use of a nuclear weapon or other WMD attack by al- Qaeda and its Jihadist allies. Here, too, new thinking will be required to define and implement such complementary strategies for influencing the calculations of terrorist adversaries. But questions about the applicability - or at least complexities - of deterrence also are reflected in today's expressions of concern that some new nuclear powers may be 'non-deterrable' as well as that an asymmetric balance of stakes is creating a new deterrence equation outside of Europe. Regarding Russia, Moscow no longer is an adversary of the West but nor is it a friend - and moving beyond deterrence to a non-adversarial relationship so far has been more rhetoric than reality. As for China, the U.S. extended nuclear deterrent continues to play a role in helping to avoid a confrontation over Taiwan as well as in reassuring those officials in Asia that are uncertain about the ultimate impact of China's rise. That said, it would be preferable to mute the role of nuclear deterrence in the U.S.-China strategic relationship and, as with Russia, to develop a non-adversarial relationship between the United States and China. From an American perspective, the following essay addresses this new, more complex agenda of the early 21. century. Specifically, it turns first to the challenge of extending deterrence to U.S. allies and

  4. Antioxidants keep the potentially probiotic but highly oxygen-sensitive human gut bacterium Faecalibacterium prausnitzii alive at ambient air.

    Directory of Open Access Journals (Sweden)

    M Tanweer Khan

    Full Text Available The beneficial human gut microbe Faecalibacterium prausnitzii is a 'probiotic of the future' since it produces high amounts of butyrate and anti-inflammatory compounds. However, this bacterium is highly oxygen-senstive, making it notoriously difficult to cultivate and preserve. This has so far precluded its clinical application in the treatment of patients with inflammatory bowel diseases. The present studies were therefore aimed at developing a strategy to keep F. prausnitzii alive at ambient air. Our previous research showed that F. prausnitzii can survive in moderately oxygenized environments like the gut mucosa by transfer of electrons to oxygen. For this purpose, the bacterium exploits extracellular antioxidants, such as riboflavin and cysteine, that are abundantly present in the gut. We therefore tested to what extent these antioxidants can sustain the viability of F. prausnitzii at ambient air. The present results show that cysteine can facilitate the survival of F. prausnitzii upon exposure to air, and that this effect is significantly enhanced the by addition of riboflavin and the cryoprotectant inulin. The highly oxygen-sensitive gut bacterium F. prausnitzii can be kept alive at ambient air for 24 h when formulated with the antioxidants cysteine and riboflavin plus the cryoprotectant inulin. Improved formulations were obtained by addition of the bulking agents corn starch and wheat bran. Our present findings pave the way towards the biomedical exploitation of F. prausnitzii in redox-based therapeutics for treatment of dysbiosis-related inflammatory disorders of the human gut.

We present a case of an unusually large left atrial myxoma discovered incidentally in a patient with longstanding dyspnea being managed as bronchial asthma.

  10. Left-handedness and health

    Directory of Open Access Journals (Sweden)

    Milenković Sanja


    Full Text Available Hand dominance is defined as a proneness to use one hand rather than another in performing the majority of activities and this is the most obvious example of cerebral lateralization and an exclusive human characteristic. Left-handed people comprise 6-14% of the total population, while in Serbia, this percentage is 5-10%, moving from undeveloped to developed environments, where a socio-cultural pressure is less present. There is no agreement between investigators who in fact may be considered a left-handed person, about the percentage of left-handers in the population and about the etiology of left-handedness. In the scientific literature left-handedness has been related to health disorders (spine deformities, immunological disorders, migraine, neurosis, depressive psychosis, schizophrenia, insomnia, homosexuality, diabetes mellitus, arterial hypertension, sleep apnea, enuresis nocturna and Down Syndrome, developmental disorders (autism, dislexia and sttutering and traumatism. The most reliable scientific evidences have been published about the relationship between left-handedness and spinal deformities in school children in puberty and with traumatism in general population. The controversy of other results in up-to-now investigations of health aspects of left-handedness may partly be explained by a scientific disagreement whether writing with the left hand is a sufficient criterium for left-handedness, or is it necessary to investigate other parameters for laterality assessment. Explanation of health aspects of left-handedness is dominantly based on Geschwind-Galaburda model about 'anomalous' cerebral domination, as a consequence of hormonal disbalance. .

  11. Left ventricular wall stress compendium. (United States)

    Zhong, L; Ghista, D N; Tan, R S


    Left ventricular (LV) wall stress has intrigued scientists and cardiologists since the time of Lame and Laplace in 1800s. The left ventricle is an intriguing organ structure, whose intrinsic design enables it to fill and contract. The development of wall stress is intriguing to cardiologists and biomedical engineers. The role of left ventricle wall stress in cardiac perfusion and pumping as well as in cardiac pathophysiology is a relatively unexplored phenomenon. But even for us to assess this role, we first need accurate determination of in vivo wall stress. However, at this point, 150 years after Lame estimated left ventricle wall stress using the elasticity theory, we are still in the exploratory stage of (i) developing left ventricle models that properly represent left ventricle anatomy and physiology and (ii) obtaining data on left ventricle dynamics. In this paper, we are responding to the need for a comprehensive survey of left ventricle wall stress models, their mechanics, stress computation and results. We have provided herein a compendium of major type of wall stress models: thin-wall models based on the Laplace law, thick-wall shell models, elasticity theory model, thick-wall large deformation models and finite element models. We have compared the mean stress values of these models as well as the variation of stress across the wall. All of the thin-wall and thick-wall shell models are based on idealised ellipsoidal and spherical geometries. However, the elasticity model's shape can vary through the cycle, to simulate the more ellipsoidal shape of the left ventricle in the systolic phase. The finite element models have more representative geometries, but are generally based on animal data, which limits their medical relevance. This paper can enable readers to obtain a comprehensive perspective of left ventricle wall stress models, of how to employ them to determine wall stresses, and be cognizant of the assumptions involved in the use of specific models.

  12. Slovenian Anti-Semitism, Buried Alive in the Ideology of Slovenian National Reconciliation

    Directory of Open Access Journals (Sweden)

    Irena Šumi


    Full Text Available Following 1991, the ideology of national reconciliation as formulated by philosopher Spomenka Hribar during the 1980s became part and parcel of the Slovenian postsocialism transition. The interpretation of the confessional clash on the occupied Slovenian soil during WWII that the ideology adopts had, and still has, numerous legal, political, cultural and social consequences. In accord with the historical essence of the Slovenian biopolitics that insists on pseudo-biological understandings of social continuities, the reconciliation ideology affirms a specific type of historic revisionism whose central point is a total silence on pre-war confessional and ideological antiSemitism on the part of the then-Slovenian Catholic Church and its close ally, the Slovenian People’s Party. The ideology of reconciliation likewise totally suppresses the wartime persecution of Slovenian Jews in the hands of collaborationist authorities, as well as post-war programmatic anti-Semitism of the revolutionary authorities. With this complete omission, the reconciliation idea not only entirely missed its declared goal, to “accept our history,” but decontextualised the history itself, and with it, distorted it. Although the idea of reconciliation in this ideational framework is a glaring political failure, it has, paradoxically, sucessfully established itself as the diacritic between the closely complementary transition political left and right even as both are, since 1991, entirely devoted to neoliberal ideologies and politics.

  13. Charles Darwin's Origin of Species, directional selection, and the evolutionary sciences today. (United States)

    Kutschera, Ulrich


    The book On the Origin of Species, published in November 1859, is an "abstract" without references, compiled by Charles Darwin from a much longer manuscript entitled "Natural Selection." Here, I summarize the five theories that can be extracted from Darwin's monograph, explain the true meaning of the phrase "struggle for life" (i.e., competition and cooperation), and outline Darwin's original concept of natural selection in populations of animals and plants. Since neither Darwin nor Alfred R. Wallace distinguished between stabilizing and directional natural selection, the popular argument that "selection only eliminates but is not creative" is still alive today. However, I document that August Weismann (Die Bedeutung der sexuellen Fortpflanzung für die Selektions-Theorie. Gustav Fischer-Verlag, Jena, 1886) and Ivan Schmalhausen (Factors of evolution. The theory of stabilizing selection. The Blackiston Company, Philadelphia, 1949) provided precise definitions for directional (dynamic) selection in nature and illustrate this "Weismann-Schmalhausen principle" with respect to the evolutionary development of novel phenotypes. Then, the modern (synthetic) theory of biological evolution that is based on the work of Theodosius Dobzhansky (Genetics and the origin of species. Columbia University Press, New York, 1937) and others, and the expanded version of this system of theories, are outlined. Finally, I document that symbiogenesis (i.e., primary endosymbiosis, a process that gave rise to the first eukaryotic cells), ongoing directional natural selection, and the dynamic Earth (plate tectonics, i.e., geological events that both created and destroyed terrestrial and aquatic habitats) were the key processes responsible for the documented macroevolutionary patterns in all five kingdoms of life. Since the evolutionary development of the earliest archaic bacteria more than 3,500 mya, the biosphere of our dynamic planet has been dominated by prokaryotic microbes. Eubacteria

  14. 'Africa Alive Corridors': Forging a new future for the people of Africa by the people of Africa (United States)

    Felix Toteu, Sadrack; Malcolm Anderson, John; de Wit, Maarten


    ' Africa Alive Corridors' (AAC) addresses major stewardship goals in Africa through a selection of 20 heritage Corridors (varying from 1000 to 4000 km in length and 50 to 100 km wide). These include more than 400 heritage nodes (World Heritage Sites, Biosphere Reserves, biodiversity hotspots, Geoparks, etc.). AAC tracks Africa's journey from around 4 billion years ago to the present day through these chronologically sequenced Corridors. And so, the 4-billion-year autobiography of the continent is told. It encompasses the geological, biological and anthropological/cultural history of Africa's 54 nations - a (hi-) story without borders. The wealth of scientific and biographical knowledge archived in this network of Corridors tells the story of continental drift, mega-geohazards, climate variability and change, and the origin and extinction of biodiversity; and includes our human roots, culture and spirituality, our impact on the Earth and our potential to influence its future. In telling this story of Africa, new research avenues will be discovered and new learning methodologies will be experienced and developed and shared. In this way, the AAC provide loci along which the eight UN-Millennium Development Goals may be readily and realistically achieved. In concert, they can form the basis for a new collective endeavour - of Pan African Earth Stewardship Science. In this, the final - 2010 - phase of IYPE (the International Year of Planet Earth), we aim to make a start at bringing the ' Africa Alive Corridors' into real-life context. Whilst the concept of the Corridors has been formulated and presented at various international forums—most recently in Africa at the launch of IYPE in Arusha, Tanzania, in May 2008—here we present in brief their conceptual framework, and summarize the rationale behind the selection of the 20 African Corridors. Then, we describe, for the first time, how the AAC concept might evolve. To achieve the latter, we focus on an exploratory

  15. Mechanical vapor compression refrigeration for low temperature industrial applications today

    International Nuclear Information System (INIS)

    Ferguson, J.E.


    If the super conductor industry settles out at a temperature of -100 0 F or above, mechanical refrigeration will be vying for the cooling business. Today there very definitely is a break point in the application of equipment at approximately -120 0 F or 189 0 K. Other technologies are generally utilized below this level. However, with market potential comes invention and breakthroughs in refrigeration can also occur. Today standard refrigeration systems are cost effective, reliable and produced in the millions for high temperature applications of +10 0 F to +40 0 F evaporator temperature. Lower temperatures require additional hardware, consume additional power and are produced today in limited quantities for special applications

  16. Left main percutaneous coronary intervention. (United States)

    Teirstein, Paul S; Price, Matthew J


    The introduction of drug-eluting stents and advances in catheter techniques have led to increasing acceptance of percutaneous coronary intervention (PCI) as a viable alternative to coronary artery bypass graft (CABG) for unprotected left main disease. Current guidelines state that it is reasonable to consider unprotected left main PCI in patients with low to intermediate anatomic complexity who are at increased surgical risk. Data from randomized trials involving patients who are candidates for either treatment strategy provide novel insight into the relative safety and efficacy of PCI for this lesion subset. Herein, we review the current data comparing PCI with CABG for left main disease, summarize recent guideline recommendations, and provide an update on technical considerations that may optimize clinical outcomes in left main PCI.

  19. Apraxia in left-handers. (United States)

    Goldenberg, Georg


    In typical right-handed patients both apraxia and aphasia are caused by damage to the left hemisphere, which also controls the dominant right hand. In left-handed subjects the lateralities of language and of control of the dominant hand can dissociate. This permits disentangling the association of apraxia with aphasia from that with handedness. Pantomime of tool use, actual tool use and imitation of meaningless hand and finger postures were examined in 50 consecutive left-handed subjects with unilateral hemisphere lesions. There were three aphasic patients with pervasive apraxia caused by left-sided lesions. As the dominant hand is controlled by the right hemisphere, they constitute dissociations of apraxia from handedness. Conversely there were also three patients with pervasive apraxia caused by right brain lesions without aphasia. They constitute dissociations of apraxia from aphasia. Across the whole group of patients dissociations from handedness and from aphasia were observed for all manifestations of apraxia, but their frequency depended on the type of apraxia. Defective pantomime and defective tool use occurred rarely without aphasia, whereas defective imitation of hand, but not finger, postures was more frequent after right than left brain damage. The higher incidence of defective imitation of hand postures in right brain damage was mainly due to patients who had also hemi-neglect. This interaction alerts to the possibility that the association of right hemisphere damage with apraxia has to do with spatial aptitudes of the right hemisphere rather than with its control of the dominant left hand. Comparison with data from right-handed patients showed no differences between the severity of apraxia for imitation of hand or finger postures, but impairment on pantomime of tool use was milder in apraxic left-handers than in apraxic right-handers. This alleviation of the severity of apraxia corresponded with a similar alleviation of the severity of aphasia as

    International Nuclear Information System (INIS)

    Rahman, N.; Tai, J.; Soofi, A.


    The transient left ventricular apical ballooning syndrome, also known as Takotsubo cardiomyopathy, is characterized by transient left ventricular dysfunction in the absence of obstructive epicardial coronary disease. Although the syndrome has been reported in Japan since 1990, it is rare in other regions. Rapid recognition of the syndrome can modify the diagnostic and therapeutic attitude i.e. avoiding thrombolysis and performing catheterization in the acute phase. (author)

  1. Left Main Coronary Artery Aneurysm

    Directory of Open Access Journals (Sweden)

    Hossein Doustkami


    Full Text Available Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. The most common cause of coronary artery aneurysms is atherosclerosis. Angiography is the gold standard for diagnosis and treatment. Depending on the severity of the coexisting coronary stenosis, patients with left main coronary artery aneurysms can be effectively managed either surgically or pharmacologically. We herein report a case of left main coronary artery aneurysm in a 72-year-old man with a prior history of hypertension presenting to our hospital because of unstable angina. The electrocardiogram showed ST-segment depression and T-wave inversion in the precordial leads. All the data of blood chemistry were normal. Echocardiography showed akinetic anterior wall, septum, and apex, mild mitral regurgitation and ejection fraction of 45%. Coronary angiography revealed a saccular aneurysm of the left main coronary artery with significant stenosis in the left anterior descending, left circumflex, and right coronary artery. The patient immediately underwent coronary artery bypass grafting and ligation of the aneurysm. At six months’ follow-up, he remained asymptomatic.

    Gervaz, P; Usel, M; Rapiti, E; Chappuis, P; Neyroud-Kaspar, I; Bouchardy, C


    Prognosis of colon cancer (CC) has steadily improved during the past three decades. This trend, however, may vary according to proximal (right) or distal (left) tumor location. We studied if improvement in survival was greater for left than for right CC. We included all CC recorded at the Geneva population-based registry between 1980 and 2006. We compared patients, tumor and treatment characteristics between left and right CC by logistic regression and compared CC specific survival by Cox models taking into account putative confounders. We also compared changes in survival between CC location in early and late years of observation. Among the 3396 CC patients, 1334 (39%) had right-sided and 2062 (61%) left-sided tumors. In the early 1980s, 5-year specific survival was identical for right and left CCs (49% vs. 48%). During the study period, a dramatic improvement in survival was observed for patients with left-sided cancers (Hazard ratio [HR]: 0.42, 95% confidence interval [CI]: 0.29-0.62, p colon cancer patients, those with right-sided lesions have by far the worse prognosis.

    International Nuclear Information System (INIS)

    Makishita, Hideo; Miyasaka, Motomaro; Tanizaki, Yoshio; Yanagisawa, Nobuo; Sugishita, Morihiro.


    We reported 7 patients with left thalamic hemorrhage in the chronic stage (from 1.5 months to 4.5 months), and described language disorders examined by Western Aphasia Battery (WAB) and measured cerebral blood flow by single photon emission CT. Examination of language by WAB revealed 4 aphasics out of 7 cases, and 3 patients had no language deficit. The patient with Wernicke's aphasia showed low density area only in the left posterior thalamus in X-ray CT, and revealed severe low blood flow area extending to left temporal lobe in emission CT. In the case with transcortical sensory aphasia, although X-ray CT showed no obvious low density area, emission CT revealed moderate low flow area in watershed area that involved the territory between posterior cerebral and middle cerebral arteries in the left temporooccipital region in addition to low blood flow at the left thalamus. In one of the two patients classified as anomic aphasia, whose score of repetition (8.4) was higher than that of comprehension (7.4), emission CT showed slight low flow area at the temporo-occipital region similarly as the case with transcortical sensory aphasia. In another case with anomic aphasia, scored 9 on both fluensy and comprehension subtests and 10 on repetition, there was wide low density area all over the left thalamus and midline shift to the right in X-ray CT, and emission CT showed severe low blood flow in the same region spreading widely toward the cerebral surface. On the other hand, in all of the 3 patients without aphasia, emission CT showed low flow region restricted to the left thalamus. (J.P.N.)

    Recent years have brought enormous changes to the specialty of diagnostic imaging and in particular to the radiology labor market. The impact of subspecialties, the increased use of advanced imaging, and lifestyle issues driving career-related and job-related decision making by young radiologists have combined to bring about a new world of recruitment. Success in attracting, hiring, and retaining desired candidates requires acceptance of today's radiology labor market conditions. Knowledge of exactly what conditions today's entry-level candidates are seeking is key. In addition, innovation in the recruitment and development of a desirable workplace can be extremely helpful. Although these challenges may be difficult for some radiology employers to accept, it may help to know that radiology is not alone. For a wide variety of reasons, some similar, some unique to particular specialties, most medical employers today must work hard and make compromises to hire the physicians they seek.

  12. Left ventricular diastolic performance of left ventricular hypertrophy

    Energy Technology Data Exchange (ETDEWEB)

    Ikezono, Tohru; Ozaki, Masaharu; Yamagishi, Takashi; Shimizu, Tatsuro; Furutani, Yuji; Kusukawa, Reizo


    To study left ventricular diastolic performance in different forms of left ventricular hypertrophy, ECG gated cardiac blood pool scan was performed in 11 patients with hypertrophic nonobstructive cardiomyopathy (HCM) and in 19 patients with hypertension (HT), and left ventricular volume curve (LVVC) was analyzed and compared with those of 13 normal subjects (N). Ejection fraction (EF) and early filling volume ratio (the ratio of volume increment of 100 msec later than the zero point in the first derivative of LVVC to the end diastolic volume) (%EFV) were computed from LVVC. Peak ejection rate (PER) and peak filling rate (PFR) were obtained from the first derivative of LVVC. Peak ejection acceleration (PEA) and peak filling acceleration (PFA) were calculated from the second derivative of LVVC. EF, PER and PEA did not show any difference between these 3 groups. PFR was lower in HT (2.6 +- 0.5) compared with those in HCM (3.0 +- 0.5) (p < 0.05) and in N (3.4 +- 0.5) (p < 0.001), but the %EFV in HCM (4.9 +- 1.8) was lower than those in HT (6.9 +- 1.9) (p < 0.01) and in N (11.4 +- 1.4) (p < 0.001). Moreover, PFA in HCM (27.9 +- 7.2) was increased than those in HT (20.2 +- 5.4) (p < 0.01) with no differences between HCM and N (29.4 +- 8.1). Significant correlation was observed between PFR and PFA (Y = 0.06X + 1.4. r = 0.856. p < 0.001). These result indicate that, in HCM, reduced increase in early left ventricular volume is compensated by a greater filling acceleration. In contrast, there is no compensation by filling acceleration in HT.

  13. A genome-wide association study in large white and landrace pig populations for number piglets born alive.

    Directory of Open Access Journals (Sweden)

    Sarah Bergfelder-Drüing

    Full Text Available The number of piglets born alive (NBA per litter is one of the most important traits in pig breeding due to its influence on production efficiency. It is difficult to improve NBA because the heritability of the trait is low and it is governed by a high number of loci with low to moderate effects. To clarify the biological and genetic background of NBA, genome-wide association studies (GWAS were performed using 4,012 Large White and Landrace pigs from herdbook and commercial breeding companies in Germany (3, Austria (1 and Switzerland (1. The animals were genotyped with the Illumina PorcineSNP60 BeadChip. Because of population stratifications within and between breeds, clusters were formed using the genetic distances between the populations. Five clusters for each breed were formed and analysed by GWAS approaches. In total, 17 different significant markers affecting NBA were found in regions with known effects on female reproduction. No overlapping significant chromosome areas or QTL between Large White and Landrace breed were detected.

  14. Charles Darwin's Origin of Species, directional selection, and the evolutionary sciences today (United States)

    Kutschera, Ulrich


    The book On the Origin of Species, published in November 1859, is an “abstract” without references, compiled by Charles Darwin from a much longer manuscript entitled “Natural Selection.” Here, I summarize the five theories that can be extracted from Darwin’s monograph, explain the true meaning of the phrase “struggle for life” (i.e., competition and cooperation), and outline Darwin’s original concept of natural selection in populations of animals and plants. Since neither Darwin nor Alfred R. Wallace distinguished between stabilizing and directional natural selection, the popular argument that “selection only eliminates but is not creative” is still alive today. However, I document that August Weismann ( Die Bedeutung der sexuellen Fortpflanzung für die Selektions-Theorie. Gustav Fischer-Verlag, Jena, 1886) and Ivan Schmalhausen ( Factors of evolution. The theory of stabilizing selection. The Blackiston Company, Philadelphia, 1949) provided precise definitions for directional (dynamic) selection in nature and illustrate this “Weismann-Schmalhausen principle” with respect to the evolutionary development of novel phenotypes. Then, the modern (synthetic) theory of biological evolution that is based on the work of Theodosius Dobzhansky ( Genetics and the origin of species. Columbia University Press, New York, 1937) and others, and the expanded version of this system of theories, are outlined. Finally, I document that symbiogenesis (i.e., primary endosymbiosis, a process that gave rise to the first eukaryotic cells), ongoing directional natural selection, and the dynamic Earth (plate tectonics, i.e., geological events that both created and destroyed terrestrial and aquatic habitats) were the key processes responsible for the documented macroevolutionary patterns in all five kingdoms of life. Since the evolutionary development of the earliest archaic bacteria more than 3,500 mya, the biosphere of our dynamic planet has been dominated by

  15. Five-year results of 206 laparoscopic left colectomies for cancer. (United States)

    Lechaux, D; Trebuchet, G; Le Calve, J L


    The purpose of this study was to evaluate the 5-year survival of 206 consecutive patients with left colon carcinoma operated with a laparoscopic procedure between March 1992 and December 2000. Patients with obstructing or bulky cancers were excluded from this study. Tumor stage was defined according to the Dukes modified classification. The laparoscopic-assisted technique included primary high vascular ligation, centrifugal dissection of the mesentery, and "no touch" technique. The survival rates were calculated with the Kaplan-Meier test. There were 109 males and 97 females, median age 67 (range 34-91). There were 30 left hemicolectomies (15%) and 177 sigmoid colectomies (85%). 22 patients required open conversion (11%). Overall operative mortality (1 month) was 1% and morbidity 12% (surgical and medical). There were 56 Dukes A carcinomas (27%), 69 Dukes B (34%), 54 Dukes C (26%), and 27 Dukes D (13%). 125 patients (61%) are alive and disease free, 22 (11%) are alive with disease recurrence, and 59 patients (28%) are deceased. None have been lost to follow-up. Only 1 case of trocar site implantation occurred after curative resections. Three-year observed survival rate were 93% for Dukes A + B (node negative tumors confined to the bowel wall), 78% for Dukes C, and 15% for Dukes D. The 5-year survival rates were 85% for Dukes A + B, 61% for Dukes C, and 8% for Dukes D. Laparoscopic colectomy for cancer seems to be a safe procedure. The long-term results are comparable to those of open surgery. Further randomized trials will be necessary to confirm the value of this technique.

  17. Seven children -- four alive. (United States)

    Mcconahay, M J


    The author reports her observations on the status of women, maternal and child health, and access to family planning services in parts of Guatemala. Her comments refer specifically to experiences in the Mezquital squatter settlement around the capital of Guatemala City, the town of Puerto Abajo 60 miles northwest of Mezquital, highland villages, and the Peten province to the North. Guatemala's population is doubling every 22 years. 10 million individuals currently inhabit the country, thus making it the most populous of Central American nations. Only 23% of Guatemalan women, however, use family planning facilities, far fewer than would like to, were services more widely available. This low rate of exposure to, and use of, contraception results in the largely expected high average of 6 children per woman in Guatemala. Guatemala is a Catholic and very conservative country; the government has not encouraged family planning and abortion is barely considered. Women in Guatemala need access to family planning services, but also education, employment, housing, and the opportunity to make productive contributions to the country. Further, single mothers and heads of households find it difficult to provide for the daily basic needs of the family, let alone worry about contraception. Basic health services protecting against preventable causes of morbidity such as cholera and intestinal worms must be provided before family sizes may be reduced and general development may take place.

  1. Game theory, alive

    CERN Document Server

    Karlin, Anna R


    This book presents a rigorous introduction to the mathematics of game theory without losing sight of the joy of the subject. This is done by focusing on theoretical highlights (e.g., at least six Nobel Prize winning results are developed from scratch) and by presenting exciting connections of game theory to other fields, such as computer science, economics, social choice, biology, and learning theory. Both classical topics, such as zero-sum games, and modern topics, such as sponsored search auctions, are covered. Along the way, beautiful mathematical tools used in game theory are introduced, including convexity, fixed-point theorems, and probabilistic arguments. The book is appropriate for a first course in game theory at either the undergraduate or graduate level, whether in mathematics, economics, computer science, or statistics. Game theory's influence is felt in a wide range of disciplines, and the authors deliver masterfully on the challenge of presenting both the breadth and coherence of its underlying ...

  3. Is Venus alive? (United States)

    Taylor, Harry A., Jr.

    Apart from the earth, the near environment of only one other planet, Venus, has been the subject of sustained in situ investigations from space. Owing to the similarity in the physical characteristics of the two bodies, this is most appropriate in that it provides the opportunity to test the credo that through comparative analysis, planetary exploration holds the promise for better understanding of our earth environment.The Pioneer Venus Orbiter was placed into orbit about Venus in December 1978 and has provided a wealth of observations of the planet surface, its atmosphere and clouds, the ionosphere, and the interaction of the solar wind and interplanetary magnetic field with the planetary environment. Among these observations, perhaps the most potentially significant and yet controversial result has been the claimed evidence of extensive lightning and the coupled assertion that the lightning is stimulated by volcanic activity. This lightning- volcanism scenario has become widely publicized in films, books, and numerous journal and magazine articles. Also, these results have had considerable influence in stimulating ongoing research on the basis that active volcanic output might explain otherwise unanswered questions in wide-ranging disciplines, including atmospheric and cloud physics, geology, and plasma physics. Quite naturally, the question of whether Venus is geologically either living or dead is fundamentally significant for comparative planetary analysis.

Harris argues that it is misguided to suggest that Hegelrsquo;s philosophical project was a dialectical illusion generated by his historical situation and that he would never have believed that his vision was achievable if he had been faced with the world that we face today. Not only does Harris proclaim himself to be a Hegelian, he claims that Hegel would today also remain a Hegelian. He goes on to argue that despite the fragmentation of the twentieth century and the apparent collapse of the vision articulated in the French Revolution, Hegelrsquo;s thinking continues to be relevant because although his philosophy is the lsquo;comprehension of onersquo;s timersquo;, Hegel also produces a philosophy that is out of time and somehow /

  10. Childhood obesity: what can be done to help today's youth? (United States)

    Henry, Linda L


    Childhood obesity is at epidemic proportions in the United States today. This epidemic has created a public health crisis. Although several initiatives are under way to address childhood obesity, including legislative bills before Congress and a call by the National Academy of Sciences for society to band together to stop the rise in the rates of childhood obesity, none of these efforts address what can be done today to help those youth that are considered morbidly obese and who have failed to find solutions with the standard medical treatment plan. This article discusses the use of bariatric surgery as a possible solution, presents a case study to illustrate the impact bariatric surgery can have on youth who are morbidly obese, and defines the pediatric nurse's role in helping to assure that youth are included in the current legislative process.

  12. Energy financing in today's world - a banker's viewpoint

    International Nuclear Information System (INIS)

    Mackrell, Ian


    If the world runs on energy, the energy industry runs on finance. Supplying the industry's huge appetite for funds -on the scale and in the form required - has always posed a major challenge to the international banking community. But in some respects that challenge is greater today than it has ever been, not only because of the industry's escalating requirements but also because of the way bank's attitudes have been changing in the recent past. One reason for this is the rapidly evolving scene within the energy business in response to the harsher competitive conditions and the greater uncertainties of tomorrow. However, the other major factor is that banking itself has been undergoing significant change as a result of severe pressures and constraints, both internal and external. Some of the key global trends and issues affecting energy financing in today's world are considered here. (author)

This increase results primarily because standard setters believe asset and liability measures that reflect current economic conditions and up-to-date expectations of the future will result in more useful information for making economic decisions, which is the objective of financial reporting. This is why sta...

  17. Energy supply today and tomorrow, national and global

    International Nuclear Information System (INIS)

    Ott, G.


    A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

  19. "Children are from heaven" or how today children respect adults

    Directory of Open Access Journals (Sweden)

    Barbara Vogrinec


    Full Text Available The starting point of the text is a returning to the patriarchal, which is not simply the one that we are witnessing today, in the time of so-called postmodern, postpatriarchal society in its (until now last form. It is a matter of returning to rules, of which the basic premise is that adults are subjects (transcendences, freedoms, activities and children are subjects that are objects for adults (imanences, non-freedoms, pasivities, but which notwithstanding differ from the oldfashioned rules from the past. We attempted to explain this returning, following the example of rules offered by the book Children Are From Heaven – a selfhelp book, published at the end of the nineties of the 20th century, which immediately became the world's bestseller. In addition, our aim was to answer the following questions: What has happened with rules of civilization and good manners, regulating the relations between children and adults today? How have they changed and what has happened with children's or adults's relation to these rules or their performings? How has this relation changed? Considering the mentioned basic premise which implies that children respect adults, we also tried to answer the question: What has happened with the respect, or, how do children respect adults today? Disscussion is presented in the framework of lacanian psychoanalysis.

  4. Flavoured Dark Matter moving left (United States)

    Blanke, Monika; Das, Satrajit; Kast, Simon


    We investigate the phenomenology of a simplified model of flavoured Dark Matter (DM), with a dark fermionic flavour triplet coupling to the left-handed SU(2) L quark doublets via a scalar mediator. The DM-quark coupling matrix is assumed to constitute the only new source of flavour and CP violation, following the hypothesis of Dark Minimal Flavour Violation. We analyse the constraints from LHC searches, from meson mixing data in the K, D, and B d,s meson systems, from thermal DM freeze-out, and from direct detection experiments. Our combined analysis shows that while the experimental constraints are similar to the DMFV models with DM coupling to right-handed quarks, the multitude of couplings between DM and the SM quark sector resulting from the SU(2) L structure implies a richer phenomenology and significantly alters the resulting impact on the viable parameter space.

  5. Clinical practice of functional electrical stimulation: from "Yesterday" to "Today". (United States)

    Dimitrijevic, Milan R


    Functional electrical stimulation (FES) is an accepted treatment method for paresis or paralysis after spinal cord and head injury as well as stroke and other neurological upper motor neuron disorders. At the beginning, FES worked like an electrophysiological brace for the correction of drop foot of patients after a stroke. When analyzing early accomplishments, it becomes evident that FES was influenced rather by technological and biomedical engineering development than by contemporary knowledge on neurocontrol of movement in individuals with upper motor neuron paralysis. Nevertheless, with better understanding of pathophysiology of spasticity and neurocontrol of impaired movement, FES advanced from an electrophysiological brace to a treatment modality for the improvement of muscle control, neuroaugmentation of residual movements, and supportive procedure for "spontaneous recovery" of motor control. In the present article we shall illustrate barriers which delayed FES to be applied in clinical practice of neuron rehabilitation from "Yesterday" to "Today." We shall discuss the importance to apply FES early after the onset of neurological conditions to prevent disuse of noninjured portions of the CNS. Moreover, FES can play a significant role in the supporting processes of neuroplasticity in the subacute phase of upper motor neuron dysfunction. Therefore, the electrophysiological brace of "Yesterday" provides "Today" a correction of missing neuromuscular function. At the same time, it is an active external device for the correction of motor deficits interacting with the somatosensory-motor integration. Thus, "Yesterday" and "Today" of the same technological approach can be very different, thanks to a different understanding and assessment of "external" and "internal" components of human motor control.

A second example is high unemployment and the concurrent shortage of IT specialists. Affirmative action has led to troublesome labour relations. HIV/AIDS has an enormous impact on business and must be managed. South African managers need to change their managerial approaches to cope with the increasing demands of this country. Managers must be aware of the realities facing them and know how to turn them into potential growth opportunities for their organisations and South Africa as a country.

    Singh, M; Cowan, S; Child, G


    Four dogs were treated for acute toxicity following ingestion of the popular garden shrub 'Yesterday, today, tomorrow' (Brunfelsia spp). Clinical signs included vomiting, diarrhoea, muscle tremors, anxiousness, opisthotonus and seizures. All dogs recovered following treatment with any or all of general anaesthetic, gastric lavage, enema, diazepam, phenobarbitone or propofol sedation. Brunfelsia spp toxicity should be considered in young, previously healthy dogs presenting with gastrointestinal signs that rapidly progress to muscle tremors and seizures. Examination of faeces was required for diagnosis in all cases. Owners should also be questioned thoroughly about their dogs' access to such plants.

  15. 3D and 4D Seismic Technics Today

    Directory of Open Access Journals (Sweden)

    Marcin Marian


    Full Text Available Years ago, exploration was done through surface observations and „divining rods“ – now, it is done by satellites, microprocessors, remote sensing, and supercomputers. In the 1970´ s, the exploration success rate was 14 percent, today, it is nearly 29 percent. Not so long ago, three – dimension (3D seismic diagnostic techniques helped recover 25-50 percent of the oil in place – now, 4D seismic helps recover up to 70 percent of the oil in place. 3D and 4D seismic and earth imaging systems also help in understanding the subsurface flow of other fluids, such as groundwater and pollutants.Seismic surveys – a technique in which sound waves are bounced off underground rock struktures to reveal possible oil and gas bearing formation – are now standard fare for the modern petroleum industry. But today’s seismic methods are best at locating „structural traps“ where faults or folds in the underground rock have created zones where oil can become trapped.

  16. Traditional agricultural practices and the sex ratio today (United States)


    We study the historical origins of cross-country differences in the male-to-female sex ratio. Our analysis focuses on the use of the plough in traditional agriculture. In societies that did not use the plough, women tended to participate in agriculture as actively as men. By contrast, in societies that used the plough, men specialized in agricultural work, due to the physical strength needed to pull the plough or control the animal that pulls it. We hypothesize that this difference caused plough-using societies to value boys more than girls. Today, this belief is reflected in male-biased sex ratios, which arise due to sex-selective abortion or infanticide, or gender-differences in access to family resources, which results in higher mortality rates for girls. Testing this hypothesis, we show that descendants of societies that traditionally practiced plough agriculture today have higher average male-to-female sex ratios. We find that this effect systematically increases in magnitude and statistical significance as one looks at older cohorts. Estimates using instrumental variables confirm our findings from multivariate OLS analysis. PMID:29338023

  17. [Picture of Paracelsus, the physician--and we today]. (United States)

    Nager, F


    This article features the question whether Paracelsus and his dark, sometimes contradictory doctrine still includes some messages for modern physician. The lonely, pugnacious fighter from Central Switzerland remains today 'confused between favour and hatred from the parties'. Some contradictory examples shall outline controversies lasting for centuries. Subsequently Paracelsus' picture of nature, man and medicine is outlined, particular his meaning of nature and work of a good physician, but also his furious often unjustified overwhelming criticism about those physicians who went astray "in the labyrinthus medicorum". Sheep-physicians and wolf-physicians are confronted mercilessly and in a black and white scheme by this Lutherus medicorum. This likewise strange as well as also fascinating picture of a physician by this man of Hohenheim does not imply a clearly conceived temple inviting for an easy academic stroll. The sketch of a temple, however, serves as a symbol for the paracelsic science of healing: Philosophy, astronomy and alchemy are the three columns for the physician. These three columns are founded on virtue, the ethos of the physician. Religion the love for god, serves as a celestial roof. Finally the author expresses his opinion, that even today 500 years later, a modern, scientifically educated physician may profit from the philosophic and ethic principles of Paracelsus, who himself was a contemporary of a time of change like we are in our days.

    Shaikh, Asad F; Joseph, Susan M; Lima, Brian; Hall, Shelley A; Malyala, Rajasekhar; Rafael, Aldo E; Gonzalez-Stawinski, Gonzalo V; Chamogeorgakis, Themistokles


    Background  Left ventricular assist devices (LVADs) have revolutionized the treatment of patients with end-stage heart failure. These devices are replaced when pump complications arise if heart transplant is not possible. We present our experience with HeartMate II (HMII (Thoratec, Plesanton, California, United States)) LVAD pump exchange. Materials and Methods  We retrospectively reviewed all cases that required pump exchange due to LVAD complication from November 2011 until June 2016 at a single high-volume institution. The indications, demographics, and outcome were extracted and analyzed. Results  Of 250 total patients with implanted HMII LVADs, 16 (6%) required pump exchange during the study period. The initial indications for LVAD placement in these patients were bridge to transplantation ( n  = 6 [37.5%]) or destination therapy ( n  = 10 [62.5%]). Fifteen patients (93.8%) required pump exchange due to pump thrombosis and 1 (6.2%) due to refractory driveline infection. Nine patients (56.2%) underwent repeat median sternotomy while a left subcostal approach was used in the remaining seven patients. Fifteen patients (93.7%) survived until hospital discharge. During the follow-up period (median, 155 days), 11 patients remained alive and 4 of these underwent successful cardiac transplantation. Conclusion  HMII LVAD pump exchange can be safely performed for driveline infection or pump thrombosis when heart transplantation is not an option. Georg Thieme Verlag KG Stuttgart · New York.

  20. An Introduction to Flight Software Development: FSW Today, FSW 2010 (United States)

    Gouvela, John


    Experience and knowledge gained from ongoing maintenance of Space Shuttle Flight Software and new development projects including Cockpit Avionics Upgrade are applied to projected needs of the National Space Exploration Vision through Spiral 2. Lessons learned from these current activities are applied to create a sustainable, reliable model for development of critical software to support Project Constellation. This presentation introduces the technologies, methodologies, and infrastructure needed to produce and sustain high quality software. It will propose what is needed to support a Vision for Space Exploration that places demands on the innovation and productivity needed to support future space exploration. The technologies in use today within FSW development include tools that provide requirements tracking, integrated change management, modeling and simulation software. Specific challenges that have been met include the introduction and integration of Commercial Off the Shelf (COTS) Real Time Operating System for critical functions. Though technology prediction has proved to be imprecise, Project Constellation requirements will need continued integration of new technology with evolving methodologies and changing project infrastructure. Targets for continued technology investment are integrated health monitoring and management, self healing software, standard payload interfaces, autonomous operation, and improvements in training. Emulation of the target hardware will also allow significant streamlining of development and testing. The methodologies in use today for FSW development are object oriented UML design, iterative development using independent components, as well as rapid prototyping . In addition, Lean Six Sigma and CMMI play a critical role in the quality and efficiency of the workforce processes. Over the next six years, we expect these methodologies to merge with other improvements into a consolidated office culture with all processes being guided by

  1. Lovable Anarchism: Campus Protest in Japan From the 1990s to Today

    Directory of Open Access Journals (Sweden)

    Carl Cassegård


    Full Text Available This is a paper on the transformation of campus activism in Japan since the 1990's. Japan's so-called freeter movements (movements of young men and women lack-ing regular employment are often said to have emerged as young people shifted their base of activism from campuses to the 'street'. However, campuses have continued to play a role in activism. Although the radical student organisations of the New Left have waned, new movements are forming among students and pre-carious university employees in response to neoliberalization trends in society and the precarization of their conditions. This transformation has gone hand in hand with a shift of action repertoire towards forms of direct action such as squatting, sit-ins, hunger strikes, and opening "cafés". In this paper I focus on the develop-ment of campus protest in Kyoto from the mid-1990s until today to shed light on the following questions: How have campus-based activists responded to the ne-oliberalization of Japanese universities? What motivates them to use art or art-like forms of direct action and how are these activities related to space? I investigate the notions of space towards which activists have been oriented since the 1990's, focusing on three notions: official public space, counter-space and no-man's-land. These conceptions of space, I argue, are needed to account for the various forms campus protest has taken since the 1990s.

  2. Compression syndrome of the left renal vein

    Energy Technology Data Exchange (ETDEWEB)

    Justich, E.


    Severe compression of the left renal vein produces a pressure gradient between it and the inferior vena cava and results in changes in haemodynamics. The cause of the narrowing is usually the aorta, less commonly the superior mesenteric artery. Compression of the left renal vein may be responsible for a number of abnormalities such as primary varicoceles, primary varices of the ovarian, renal, pelvic and ureteric veins on the left, the more frequent occurrence of unilateral renal vein thrombosis on the left and the development of renovascular hypertension. One hundred and twenty-three selective phlebograms of the left renal vein and CT examinations of this structure in a further 87 patients acting as a control group were carried out. The significance of compression of the left renal vein as an aetiological factor in the development of the above mentioned abnormalities is discussed.

  4. Speaking from experience: today's Cuban women and breast cancer. (United States)

    Núñez, Marta


    Over 2200 new cases of breast cancer are diagnosed annually in Cuba, and a decade ago I became one of them. Late in 2000, I underwent breast cancer surgery at the National Oncology and Radiology Institute in the Cuban capital. My experience-both with the disease and as a sociologist at the University of Havana studying gender relations-serves as the basis for the following essay. The article characterizes today's Cuban women, particularly those of us with or at risk of breast cancer, and describes my own and others' responses to our disease. My aim is to provide insights useful to the physicians, nurses, engineers, physicists, technicians, and service and administrative workers in Cuba's health services who interact with us, whose increased awareness will make us feel more deeply understood and respected. In this context, I also reflect on the Cuban media's portrayal of cancer, with recommendations for dismantling the biases of fatalism and even pity often conveyed.

  5. The situation of hepatosplenic schistosomiasis in Brazil today

    Directory of Open Access Journals (Sweden)

    Andrade Zilton A


    Full Text Available Specific chemotherapy against schistosomiasis together with environmental changes occurring in endemic areas of Brazil are causing a revolution in the clinico-pathological presentation of the disease when comparing to date from 10 to 15 years ago. To update the subject, an inquire was made among the most experienced Brazilian investigators in this field. They agree that a decrease of about 50 to 70% in prevalence, and an even higher decrease in incidence are taking place in Brazil today. The prevalence of schistosome-infection has decreased in some areas and increased in other, with spreading sometimes occurring to peri-urban regions, indicating that schistosomiasis control depends on the application of multiple measures. General clinical and pathological manifestations related to hepatosplenic disease, such as ascites, gastric hemorrhages, big-spleen syndrome, cor pulmonale, glomerulopathy, etc. are also less severe nowadays than they used to be in the past

  7. Hegel Today: Towards a Tragic Conception of Intercultural Conflicts

    Directory of Open Access Journals (Sweden)

    Karin G de Boer


    Full Text Available This essay draws on Hegelrsquo;s conception of tragedy in the emPhenomenology/em to reinterpret the intercultural conflicts that confront us today. It is argued that the prevailing self-conception of modern states, relying on the opposition between universality and particularity, effaces the irresolvable entanglement of contrary values such as progress and tradition or reason and faith. The essay seeks to employ Hegelrsquo;s insight into the dynamic of tragic conflicts to conceptualize precisely this entanglement. This requires, however, that the tragic strand of this insight be extricated from the predominant optimism of Hegelrsquo;s dialectics as a whole. By turning this tragic strand into a conceptual perspective of its own, this essay seeks to account for the inherent tendency of contending cultural paradigms to oppose their counterpart instead of recognizing themselves in the other.nbsp; br /

  8. Medical Malpractice: Reform for Today's Patients and Clinicians. (United States)

    Stamm, Jason A; Korzick, Karen A; Beech, Kristen; Wood, Kenneth E


    The current system of medical malpractice does a poor job of serving the best interests of physicians or patients. Economic and societal forces are shifting the nature of health care from the individual physician to a system of health care professionals, characterized by accountable care organizations. In particular, more physicians are employed, quality and outcomes are routinely measured, and reimbursement is moving to value-based purchasing. Medical malpractice likewise needs to transition to a new model that is consistent with the modern era of patient-centered care. Collective accountability, the concept that patient care is the responsibility of all the members of the health care organization, requires malpractice reform that reflects a systems-based practice of medicine. Enterprise liability, coupled with medical error communication and resolution programs, provides the legal framework necessary for the patient-centered practice of medicine in today's environment.

  9. Spectroscopic Analysis of Today's Compact Fluorescent Light Bulbs (United States)

    Pluhar, Edward


    In today's consumer market, there are many different light bulbs that claim to produce `natural' light. In my research, I both quantitatively and qualitatively analyzed this claim. First, utilizing a spectroscope, I compared the spectra emitted by different brands and types of compact fluorescent light (CFL) bulbs to the spectra emitted by the Sun. Once the bulbs were quantitatively analyzed, I proceeded to qualitatively analyze them by exposing subjects to the different bulbs. The subjects were asked to rate the quality of color in different pictures illuminated by each type of CFL. From these tests, I was able to determine the ``best'' CFL bulbs, and conclude whether the health risks associated with CFL bulbs outweigh the cost savings, longevity of the bulbs, and/or quality of light benefits.

  10. Big Data, the perfect instrument to study today's consumer behavior

    Directory of Open Access Journals (Sweden)

    Cristina STOICESCU


    Full Text Available Consumer behavior study is a new, interdisciplinary and emerging science, developed in the 1960s. Its main sources of information come from economics, psychology, sociology, anthropology and artificial intelligence. If a century ago, most people were living in small towns, with limited possibilities to leave their community, and few ways to satisfy their needs, now, due to the accelerated evolution of technology and the radical change of life style, consumers begin to have increasingly diverse needs. At the same time the instruments used to study their behavior have evolved, and today databases are included in consumer behavior research. Throughout time many models were developed, first in order to analyze, and later in order to predict the consumer behavior. As a result, the concept of Big Data developed, and by applying it now, companies are trying to understand and predict the behavior of their consumers.

  11. Anarchy, socialism and a Darwinian left. (United States)

    Clarke, Ellen


    In A Darwinian left Peter Singer aims to reconcile Darwinian theory with left wing politics, using evolutionary game theory and in particular a model proposed by Robert Axelrod, which shows that cooperation can be an evolutionarily successful strategy. In this paper I will show that whilst Axelrod's model can give support to a kind of left wing politics, it is not the kind that Singer himself envisages. In fact, it is shown that there are insurmountable problems for the idea of increasing Axelrodian cooperation within a welfare state. My surprising conclusion will be that a Darwinian left worthy of the name would be anarchistic.

  12. What is Beyond Right/Left?

    Dyrberg, Torben Bech


    The article looks at New Labour's move beyond right/left in the mid/late 1990s, which is an occasion to spell out the nature of right/left and what it means for democracy. In contrast to both defenders and critics of this move I argue in the first part that right/left is not an empty label bound up...... right/left. I argue that the new hegemonic orientation is that of front/back, which designs political renewal as a response to the social changes cutting across the outdated lines of contestation of partisan politics. The democratic problem of this move lies in squeezing politics between technocratic...

  14. The simplest "field" methods for extractin of nematodes from plants, wood, insects and soil, with additional description how to keep extracted nematodes alive for a long time. (United States)

    Ryss, A Yu


    The simplest modification of the dynamic extraction method using cottonwool filter based on the Baermann funnel principle, is described. This modification excludes the funnel because a great share of Sticky worms attach to sloping walls of a funnel and thus do not reach the collector Eppendorf tube. But the main principle of the Baermann funnel is used, I. e. sinking down of actively moving heavy narrow bodies via wide holes of filter and thus separating the active worms from passive non-Brownian moving substrate particles, which do not pass the filter and remain above it. This principle is illustrated because it has never been described before. In the proposed modification any sloping walls in the extraction paths are excluded and thus the probability to attach sticky nemotodes to walls is also excluded; only cylindrical equipment with abrupt vertical walls is used; procedures are extremely simplified to be user-friendly for beginners: only filter (cotton pads), Eppendorf tubes, plastic glasses and narrow PVC tubing are applied. The new simplified modification allows one to collect nematodes by non-professional workers, e. g. in Polar expeditions without microscopic study of results. As an addition, an efficient method to maintain extracted nematodes alive is proposed, using the "effect of water film" in foam rubber inside the Eppendorf tube. To maintain nematodes alive during several months it is recommended to suppress bacteria via addition of 0.2-0.4% formaldehyde solution and then keep the tube with nematodes in a refrigerator.

  15. Research network involving retired experts as a means to keep alive relevant knowledge - The case of IPEN in Brazil

    Barroso, A.C.O.; Imakuma, K.; Reis, J.S.B. Jr.


    Full text: On one hand, by appraising the drivers that influence energy policies worldwide, one come to the conclusion that the prospects for a revival nuclear power deployment have never been so clearly designed. On the other hand, looking to what has been the situation over the last twenty years, it is evident that, should the revival come to strength in the next five to ten years, one will run into knowledge shortage problems of many kinds. This feeling, which is the tip of an iceberg, has been constantly alerted by almost everyone studying the scenario and these concerns, thanks to the proactive and catalytic role of the IAEA, gave rise to the growing field of nuclear knowledge management - NKM. Despite the repeated recommendations of IAEA, the Brazilian nuclear area as a whole is not making coordinated efforts in this concern. Reasons are many, but probably the root cause resides in the fact that the country does not have a nuclear program or a clear policy concerning the role of nuclear in the Brazilian electricity generation matrix. There are, however, some isolated initiatives in some institutions concerning mapping, diagnostic and preservation of critical nuclear knowledge. This work has studied a social network - SN that has emerged naturally and that is helping to transfer and keep alive the knowledge of retired experts at IPEN. Enabling and driving factors that have strongly contributed to the network formation and its sustainability can be summarized as: 1) The fact that Human resources of IPEN belong to a special career of science and technology for which to have master and doctor degrees represent significant salary increases. 2) The location of IPEN, sited in the campus of the country's leading university, Sao Paulo University - USP and the special institutional arrangement under which it functions as the nuclear technology unit of this university. Researchers of IPEN, with doctor degree and teaching abilities, can become also professors of graduate

  1. A new clinical sign probably associated to left hemiplegia with left hemineglect syndrome: the crossed legs. (United States)

    Bazan, Rodrigo; Fernandes, Thiago; Braga, Gabriel; Luvizutto, Gustavo; Resende, Luiz


    To describe a new clinical sign associated with left unilateral neglect syndrome (UNS) in patients with ischemic stroke. Head computed tomography (CT) and National Institute of Health Stroke Scale were obtained in 150 patients with ischemic stroke. Those with right cerebral vascular lesions, left hemiplegia and right leg persistently crossed over the left were submitted to specific tests for UNS. The tests were also applied to 30 patients with right cerebral vascular lesions, left hemiplegia but without crossed legs. From 9 patients with persistent tendency to cross the right leg over the left, UNS was detected in 8. One patient died before the clinical tests were applied. Of the 30 patients without the crossed legs, 20 had normal clinical tests for UNS and 10 had minimal alterations, not sufficient for the diagnosis of UNS. The right leg crossed over the left may represent a new neurological semiotic sign associated with left hemiplegia and left UNS.

  3. The power of data: structural bioinformatics yesterday and today

    KAUST Repository

    Tramontano, Anna


    The protein structure database was established in 1971. At the time it contained seven structures, today there are more than 100,000. The improvement is not only a matter of quantity, but also of quality. Did we effectively exploit this information to gain knowledge? The answer is certainly affirmative. I will illustrate how this wealth of experimental data has allowed us to explore the landscape of macromolecular structures on one side, and to uncover the properties of specific protein families on the other. The latter plays an essential role in pursuing exciting new avenues in biomedical and biotechnological sciences. Experimental data are also part of a virtuous cycle whereby they reinforce and guide our ability to infer unknown macromolecular structures, which, while providing relevant information to scientists, permits to gauge the level of our understanding of the complex problem of protein folding. A paradigmatic example of the latter is represented by the “Critical Assessment of Techniques for Protein Structure Prediction” (CASP) initiative that I will briefly discuss.

  4. Domestic violence: a complex health care issue for dentistry today. (United States)

    Kenney, John P


    As a natural outgrowth of the dental professional's role in recognizing and reporting child abuse the topic has been broadened in recent years to domestic violence, that is child, spouse/intimate partner, disabled and elder abuse. Forty years ago in the US there were 662 cases of child abuse reported to authorities. Today that reported number is in excess of 3 million per year [D. Wiese, D. Daro, Current trends in reporting and fatalities; the results of the 1994 annual 50 state survey, National Committee to Prevent Child Abuse, Working Paper 808, 1995]. The "dirty secret" of spousal/intimate partner violence is believed to affect 3-4 million individuals per year in the US. Studies have also found that between 50 and 70% of these perpetrators also abuse their children or those of their intimate partner [J. Kessman, Domestic violence, identifying the deadly silence, Texas Dent. J. (2000) 43]. Just as child abuse is most often manifested in the head or neck regions, likewise the evidence of physical violence to intimate partners and the elderly can be seen in the head or neck regions. The insidious part of partner and elder abuse is that often the largest component of these behaviors is psychological, emotional and indirect neglect, which leave no physical evidence [M. Bowers, Forensic Dental Evidence: An Investigator's Handbook, Elesevier, San Diego, CA, 2004, p. 119].

  5. Financial Management in Children: Today Need, Tomorrow Necessity

    Directory of Open Access Journals (Sweden)

    Tooraj Sadeghi


    Full Text Available Nearly 80% of young people today will never be able to retire. Why? Because they lack the personal finance training that leads to long-term planning and future security. Connecting the dots between kids and money management skills prepares them for the financial realities the world will face over the next century. Pocket money is one of the first ways for children to learn the basics of managing money – a skill they’ll definitely need for life – and it makes children feel independent. Whether to give pocket money, and at what age, and how much to give are issues that often concern parents. There are many ways to handle this. To a large extent it depends on family values, practices and finances. The main reason for giving children pocket money is to help children learn to be able to manage money while they are still young and parents can guide them. It also may help children to feel that they are important members of the family, because they are given part of the family's spending money.

  6. Teenage Mothers Today: What We Know and How It Matters. (United States)

    Mollborn, Stefanie


    Over the past two decades, births to U.S. teenagers have fallen and no longer follow overall fertility patterns. Yet the unique challenges faced by teenage mothers and their families justify continued research. Across disciplines, newer work has furthered our understanding of teenage motherhood today. In this article, I highlight four areas of progress: processes of selection into teenage motherhood, the broader consequences of teenage childbearing beyond the socioeconomic realm, heterogeneity of effects, and the application of life course principles. Emerging societal trends such as complex family structures, a stalled recovery from the recession for families of low socioeconomic status, and a rapidly evolving political environment for reproductive health care continue to challenge the lives of teenage mothers. Given that the consequences for teenagers of becoming mothers may change, continued research is needed. Shifts in policy to favor supporting teenage mothers and addressing the causes of both teenage pregnancy and social disadvantage may help improve the lives of these mothers and their families.

  7. [Being a family today - ethics for assisted reproductive techniques]. (United States)

    Mathieu, S


    Currently in France, all the children born as a result of an assisted reproduction procedure, represent 2.5% of all births. Although this proportion is not high, it is not to be neglected, particularly with regard to the sociological issues raised by assisted reproduction technologies (ART) - i.e. removing anonymity of gamete donation, post mortem insemination, ART access to single women and gay couples, surrogacy - to name four of the most prominent debates. What is new with ART is that a new therapeutic target of medicine is being developed, in other words procreation. Now it is no longer necessary for a man and a woman to resort to sex to have a child. This is a profound questioning of the representation of what appeared to be intangible, with some sort of divine aura. How, in this context, developing an ethics for ART? From a fethnographic field survey, we show here how this ethos of ART develops and how, therefore, we consider the multiple ways of being a family today. Copyright © 2013.

  9. Accuracy and reliability of gyro measurements at today's tunnelling projects (United States)

    Heunecke, Otto; Liebl, Wolfgang


    Gyro theodolites - briefly gyros - allow the orientation transfer from a reference line to another line without need for a connecting geodetic network. They are routinely used for orientation control of networks in tunnelling projects. This is currently the only way to stabilize accuracy and reliability in tunnelling networks and is indispensable with respect of today's requirements for excavation and breakthrough accuracy. In order to archive a reliable assessment of correctness, the measuring method has to be planned in a way that systematic influences in the determination of an underground directional angle are minimized. For this purpose, the principle of differential measurements is used for an azimuth determination both in terms of time as well as in space. All required corrections and reductions must be considered correctly to obtain the directional angle of interest with a measurement uncertainty less than 1 mgon ({\\wedge }=3.3^''). Some accuracy considerations obtained from own experiences are discussed to state whether the specified standard deviations of the used gyros according to DIN 18723-7 can be confirmed.

  11. U.S. bioremediation market: Yesterday, today, and tomorrow

    International Nuclear Information System (INIS)

    Devine, K.


    The use of bioremediation for full-scale cleanup has increased dramatically throughout the past 10 years. This growth in activity is expected to continue through the year 2000. It is estimated that fewer than 10 companies offered field-level bioremedial services prior to 1985. Although the market today still is dominated by a small number of companies, the total number of firms claiming to offer services and/or products for bioremediation purposes has grown to over 1,000. It is estimated that aggregate bioremediation revenues for 1994 through 2000 will equal $2 to $3 billion (1994 dollars). This revenue will be generated in the initial part of this 7-year period primarily from underground storage cleanup, with revenues from hazardous waste sites becoming an increasingly important factor by accounting for the majority of revenues in the latter years. Market opportunities exist in technology development and implementation including biosparging, centralized treatment facilities for petroleum-contaminated soils, biofilters, and improvements in the cost-effectiveness of the technology

    Today's Leaders for a Sustainable Tomorrow is a collaboration of five residential environmental learning centers (Audubon Center of the North Woods, Deep Portage Learning Center, Laurentian Environmental Center, Long Lake Conservation Center and Wolf Ridge Environmental Learning Center) that together increased energy efficiency, energy conservation and renewable energy technologies through a number of different means appropriate for each unique center. For energy efficiency upgrades the centers installed envelope improvements to seal air barriers through better insulation in walls, ceilings, windows, doors as well as the installation of more energy efficient windows, doors, lighting and air ventilation systems. Through energy sub-meter monitoring the centers are able to accurately chart the usage of energy at each of their campuses and eliminate unnecessary energy usage. Facilities reduced their dependence on fossil fuel energy sources through the installation of renewable energy technologies including wood gasification, solar domestic hot water, solar photovoltaic, solar air heat, geothermal heating and wind power. Centers also installed energy education displays on the specific renewable energy technologies used at the center.

  13. What are today's choices for PWRs water chemistry?

    International Nuclear Information System (INIS)

    Berge, P.


    Water chemistry has always been, from the very beginning of operation of power Pressurized Water Reactors (PWRs), an important factor in determining the integrity of many reactor components. For both the primary and secondary coolant circuits, the parameters to control the quality of the chemistry have been subject to changes in time. These changes were dictated mainly by corrosion problems which required an adjustment of the chemistry, before any modification could be made in the design or the selection of materials for the subsequently built reactors or replacement components. The situation today, despite 40 years of experience, still leaves open different options for the specifications of the chemistry of the circuits. These options are sometimes due to differences in design or materials of the circuits, but more often, to the perception by the plant chemists, of the role of the chemistry on the different phenomena which could affect the operation of their plant. Paul Cohen, who was well known in the nuclear industry for the early development of the chemistry in PWRs in the USA, used to say, 'if the head chemist has changed in a plant, the chemistry will change'. The purpose of this lecture is to discuss some of the options which are offered to the chemist in compliance with the basic principles of the chemistry guidelines. (J.P.N.)

  14. [Childhood in flux--Part II: Modern times until today]. (United States)

    Hardt, Jochen; Hoffmann, Sven Olaf


    At the end of the 19th century, the Society for the Prevention of Cruelty to Children was founded in New York, after a barbarous case of neglect and abuse of a girl became public. From then on, children received more and more protection. Only in the 1950s were doctors in the USA bound by law to report cases of putative physical abuse to officials. In Sweden, physical punishment of children has been forbidden since 1989, and in Germany since 2001. The existence of sexual abuse of children had been a taboo subject for centuries, even though individual attempts to break that taboo were made--e. g., by S. Freud in the theory of seduction (Verführungstheorie). Only with the birth of the women's liberation movement in the early 1970s has public awareness arisen. Due to the work of J. Bowlby in the 1950s, it became clear that children of primates need more than air, water and food, namely a relationship between the child and an adult person (attachment). To what degree the basic needs of children are being fulfilled in Western societies today is still a controversial issue.

  15. The analytic setting today: using the couch or the chair? (United States)

    Wiener, Jan


    This paper re-visits Murray Jackson's 1961 paper in the Journal of Analytical Psychology, 'Chair, couch and countertransference', with the aim of exploring the role of the couch for Jungian analysts in clinical practice today. Within the Society of Analytical Psychology (SAP) and some other London-based societies, there has been an evolution of practice from face-to-face sessions with the patient in the chair, as was Jung's preference, to a mode of practice where patients use the couch with the analyst sitting to the side rather than behind, as has been the tradition in psychoanalysis. Fordham was the founding member of the SAP and it was because of his liaison with psychoanalysis and psychoanalysts that this cultural shift came about. Using clinical examples, the author explores the couch/chair question in terms of her own practice and the internal setting as a structure in her mind. With reference to Bleger's (2013) paper 'Psychoanalysis of the psychoanalytic setting', the author discusses how the analytic setting, including use of the couch or the chair, can act as a silent container for the most primitive aspects of the patient's psyche which will only emerge in analysis when the setting changes or is breached. © 2015, The Society of Analytical Psychology.

    To present the Mediterranean diet (MD) pyramid: a lifestyle for today. A new graphic representation has been conceived as a simplified main frame to be adapted to the different nutritional and socio-economic contexts of the Mediterranean region. This review gathers updated recommendations considering the lifestyle, dietary, sociocultural, environmental and health challenges that the current Mediterranean populations are facing. Mediterranean region and its populations. Many innovations have arisen since previous graphical representations of the MD. First, the concept of composition of the 'main meals' is introduced to reinforce the plant-based core of the dietary pattern. Second, frugality and moderation is emphasised because of the major public health challenge of obesity. Third, qualitative cultural and lifestyle elements are taken into account, such as conviviality, culinary activities, physical activity and adequate rest, along with proportion and frequency recommendations of food consumption. These innovations are made without omitting other items associated with the production, selection, processing and consumption of foods, such as seasonality, biodiversity, and traditional, local and eco-friendly products. Adopting a healthy lifestyle and preserving cultural elements should be considered in order to acquire all the benefits from the MD and preserve this cultural heritage. Considering the acknowledgment of the MD as an Intangible Cultural Heritage of Humanity by UNESCO (2010), and taking into account its contribution to health and general well-being, we hope to contribute to a much better adherence to this healthy dietary pattern and its way of life with this new graphic representation.

  17. Interfaith education: A new model for today's interfaith families (United States)

    Gordon, Sheila C.; Arenstein, Benjamin


    With societal changes rapidly transforming cultures that had been largely homogenous, today's multi-cultural - and in particular interfaith - families need new educational strategies to help them understand their cultural roots and identify and clarify what aspects of their heritages they wish to nurture and transmit to their children. This paper focuses on a new model for religious education, namely non-doctrinaire "dual-faith" education, which the principal author has helped to develop in the United States (US) through the Interfaith Community (IFC), a small, independent non-profit organisation created and led by dual-faith Jewish/Christian families. The model is premised on the notion that families can have two different faiths in one household and that - with respect and education - families can be harmonious, religion can be transmitted, and tolerance broadly nurtured. While the model is particular to the US and to families with Jewish and Christian heritages, its premises and structure have significant potential to be adaptable to other religious combinations and other cultures and countries. After reviewing relevant literature and situating the IFC model in the global and US contexts, the paper sets out to clarify the importance of the concept, describe its elements, and discuss its implications for religious education in this time of changing ethos and demography.

    Full Text Available This paper aims to contribute to a constructive debate on human rights. The two World Wars of the last century brought about the creation of the United Nations aimed “to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small”. Only three years later the Universal Declaration of the Human Rights was elaborated and promoted by the UN, considered to be the foundation of international human rights law. Today, as globalization brings all closer together in a “global village”, one can see that there are many ways to perceive and guarantee human rights, in different states, but also within different states. Poverty, illiteracy, censorship, cruel treatment and even the lack of guarantee for the right to life are, unfortunately, the norm for many people of the world. Such observations bring up questions regarding the legitimacy, universality and coherence of human rights.

  1. Social aspects of left-handedness

    Directory of Open Access Journals (Sweden)

    Belojević Goran


    Full Text Available Throughout human history left-handedness has been considered as sinful. It has been associated with the devil, weakness, female gender, unhealthiness, evil, something that has to be turned to a “good” - right side by force. Left-handedness is being more and more acceptable at rational level, but in everyday life it is still considered to be unusual if someone writes with the left hand. Lessening of the number of lefthanders is associated with ageing. There are about 13% lefthanders among people in twenties and less than 1% lefthanders among those in eighties. This finding may be explaned with more pronounced socio-cultural pressure on left-handed people in the past, compared to nowadays. On the other hand, this may also support the hypothesis about a reduced life span of lefthanded people. With cross-exercising of left-handedness, certain typical characteristics and behavioral patterns appear in these people. This was a sort of provoked behavior and an attack on the integrity of an emotional attitude toward oneself. Stuttering may also appear as a consequence of unsuccessful cross-exercising of left-handedness. The hypothesis about left-handedness as an advantage is supported with the reports about relatively more lefthanders in some specific groups such as: mathematicians, sculptors, architects, painters, musicians, actors, tennis players, as well as famous army commanders and rulers.

    Full Text Available Mobile laser scanning systems (MLS offer a great potential for acquiring detailed point cloud data of urban and suburban surroundings with minimum effort. In this paper a new solution for MLSs is presented, requiring solely a combination of a profile laser scanning device and systems that are included in today's serialized end consumer vehicles. While today's mobile laser scan systems require different and expensive additional hardware that needs to be mounted onto the vehicle, the devices included within vehicle electronics offer good alternatives without additional costs.The actual scan consists of a continuous profile scan together with information gathered from on-board sensor modules. In a post- processing step, the sensor data is used to reconstruct the car's trajectory for the period of the scan and, based on this information, the track of the scan device for every measured laser pixel. Synchronization of pixel data and vehicle movement is realized via a timestamp signal which is transmitted to the car's field bus system and the scan device. To generate the final point cloud scenario, the trajectory is interpolated for every single scan point and used to convert its local position within the profile into the global coordinate system (Fig.1, Left.

METHODS: Twenty-three patients with pre-implant QRS...... complex >150 ms, QRS complex narrowing under CRT, and sinus rhythm were included ≥3 months after CRT implantation. Echocardiographic assessment of left ventricular ejection fraction (LVEF), global peak systolic longitudinal strain (GLS), and contraction pattern by 2D strain was performed during intrinsic......V pacing. CONCLUSIONS: The acute effect of tLVp on LV systolic function and contraction pattern is significantly lower than the effect of BiV pacing and not different from intrinsic conduction in patients with LBBB and CRT....

  4. [Vectorcardiographic manifestations of left intraventricular conduction disorders]. (United States)

    de Micheli, A; Medrano, G A


    Both, the vectorcardiographic changes produced by the various degrees of left bundle branch block and these observed with the different types of left distal block, are described. When a "wave jumping" phenomenon exists, the vectorcardiographic changes are more characteristic in the horizontal plane than in the frontal plane and can be interpreted satisfactorily in basis of the ventricular activation sequence. The normal counterclockwise rotation of the horizontal vectorcardiogram persists in the presence of left bundle branch block of slight and moderate degrees, since the electromotive forces of the free left ventricular wall are still predominant. In the majority of intermediate degree blocks, the middle portion of the RH loop develops with a clockwise rotation and general aspect with a clockwise rotation and the general aspect of the ventricular loop resembles an eight figure. This is due to the electromotive forces originated by the delayed depolarization of the left septal mass that starts to predominate. With advanced degrees of block, the largest portion of the RH loop shows a clockwise rotation, as well as marked notchings and slurrings. The initial anterior portion of the horizontal vectorcardiogram does not disappear, but is situated to the left of the anterior-posterior axis with a counterclockwise rotation (first right septal vector). Otherwise, the direct electrical sign of left distal block emphasized: evidence of delayed activation in a limited zone of the homolateral ventricle. This local delay gives rise to an asynchronism of the activation phenomenon between the upper and lower regions of the ventricle. The diagnosis of left bifascicular block is based essentially on the evidence of unequal delay of the activation sequence in the basal regions and in the inferior ones of the homolateral ventricle and also on the frequent persistence of the first left septal vector.

  5. The ultimately accountable job: leading today's sales organization. (United States)

    Colletti, Jerome A; Fiss, Mary S


    In recent years, sales leaders have had to devote considerable time and energy to establishing and maintaining disciplined processes. The thing is, many of them stop there--and they can't afford to, because the business environment has changed. Customers have gained power and gone global, channels have proliferated, more product companies are selling services, and many suppliers have begun providing a single point of contact for customers. Such changes require today's sales leaders to fill various new roles: Company leader. The best sales chiefs actively help formulate and execute company strategy, and they collaborate with all functions of the business to deliver value to customers. Customer champion. Customers want C-level relationships with suppliers in order to understand product strategy, look at offerings in advance, and participate in decisions made about future products--and sales leaders are in the best position to offer that kind of contact. Process guru. Although sales chiefs must look beyond the sales and customer processes they have honed over the past decade, they can't abandon them. The focus on process has become only more important as many organizations have begun bundling products and services to meet important customers' individual needs. Organization architect. Good sales leaders spend a lot of time evaluating and occasionally redesigning the sales organization's structure to ensure that it supports corporate strategy. Often, this involves finding the right balance between specialized and generalized sales roles. Course corrector. Sales leaders must watch the horizon, but they can't take their hands off the levers or forget about the dials. If they do, they might fail to respond when quick adjustments in priorities are needed.

  6. Astronomy Cast Live: Live Blogging Today's Science to the World (United States)

    Bemrose-Fetter, Rebecca; Gay, P. L.; Astronomy Cast LIVE Team


    In today's digital, on-demand society, consumers of information both want to know exactly what is happening as it is happening, and to be able to subscribe to content of their choosing. Meeting the needs of these tech savvy individuals are bloggers, podcasters and vodcasters. Using text, audio, and video to reach their respective audiences, these communicators are the new face of public outreach and journalism, but even their communications means are starting to become passé in the face of live blogging. The idea behind live blogging is simple: Take any person - even an undergraduate - with an Internet connected device, put them someplace interesting, and have them report on what they are seeing and experiencing online in real-time. This new tool is bringing astronomy enthusiasts around the world the thrill of live astronomy announcements, attending talks in real, and being "in the room" with astronomers via an Internet connection. These audiences can be anyone, from any nation, with any age. Beyond the public communications benefits of this program, it is also a program that allows the participation of early undergraduate students in science conferences. To date, two undergraduate students and five E/PO professionals have live blogged text, audio, and video content from three science conferences and a shuttle launch. Together, they have produced over 200 hundred stories that have reached tens of thousands of people around the world. In this poster we describe how we have made astronomy live blogging a reality from both the technical and personal standpoint. This project is funded through NSF grant # 0744944.

  7. Evolutionary biology today and the call for an extended synthesis. (United States)

    Futuyma, Douglas J


    Evolutionary theory has been extended almost continually since the evolutionary synthesis (ES), but except for the much greater importance afforded genetic drift, the principal tenets of the ES have been strongly supported. Adaptations are attributable to the sorting of genetic variation by natural selection, which remains the only known cause of increase in fitness. Mutations are not adaptively directed, but as principal authors of the ES recognized, the material (structural) bases of biochemistry and development affect the variety of phenotypic variations that arise by mutation and recombination. Against this historical background, I analyse major propositions in the movement for an 'extended evolutionary synthesis'. 'Niche construction' is a new label for a wide variety of well-known phenomena, many of which have been extensively studied, but (as with every topic in evolutionary biology) some aspects may have been understudied. There is no reason to consider it a neglected 'process' of evolution. The proposition that phenotypic plasticity may engender new adaptive phenotypes that are later genetically assimilated or accommodated is theoretically plausible; it may be most likely when the new phenotype is not truly novel, but is instead a slight extension of a reaction norm already shaped by natural selection in similar environments. However, evolution in new environments often compensates for maladaptive plastic phenotypic responses. The union of population genetic theory with mechanistic understanding of developmental processes enables more complete understanding by joining ultimate and proximate causation; but the latter does not replace or invalidate the former. Newly discovered molecular phenomena have been easily accommodated in the past by elaborating orthodox evolutionary theory, and it appears that the same holds today for phenomena such as epigenetic inheritance. In several of these areas, empirical evidence is needed to evaluate enthusiastic speculation

  8. Undergraduate Biocuration: Developing Tomorrow's Researchers While Mining Today's Data. (United States)

    Mitchell, Cassie S; Cates, Ashlyn; Kim, Renaid B; Hollinger, Sabrina K


    Biocuration is a time-intensive process that involves extraction, transcription, and organization of biological or clinical data from disjointed data sets into a user-friendly database. Curated data is subsequently used primarily for text mining or informatics analysis (bioinformatics, neuroinformatics, health informatics, etc.) and secondarily as a researcher resource. Biocuration is traditionally considered a Ph.D. level task, but a massive shortage of curators to consolidate the ever-mounting biomedical "big data" opens the possibility of utilizing biocuration as a means to mine today's data while teaching students skill sets they can utilize in any career. By developing a biocuration assembly line of simplified and compartmentalized tasks, we have enabled biocuration to be effectively performed by a hierarchy of undergraduate students. We summarize the necessary physical resources, process for establishing a data path, biocuration workflow, and undergraduate hierarchy of curation, technical, information technology (IT), quality control and managerial positions. We detail the undergraduate application and training processes and give detailed job descriptions for each position on the assembly line. We present case studies of neuropathology curation performed entirely by undergraduates, namely the construction of experimental databases of Amyotrophic Lateral Sclerosis (ALS) transgenic mouse models and clinical data from ALS patient records. Our results reveal undergraduate biocuration is scalable for a group of 8-50+ with relatively minimal required resources. Moreover, with average accuracy rates greater than 98.8%, undergraduate biocurators are equivalently accurate to their professional counterparts. Initial training to be completely proficient at the entry-level takes about five weeks with a minimal student time commitment of four hours/week.

    Full Text Available Hearing the words “international migration”, two things might come to our mind. One of them is the emigration process and the other is the wave of refugees. In our study, we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Nowadays, the examination of the migration potential is an important topic in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth became even faster after 2010. The reason of the acceleration was the opening of the Austrian and German labour market. The actuality of the topic is based on the fact that international emigration merges the labour market’s processes, influences the given country’s employment level, moreover it has an influencing role on the rate of wages. Emigration from a given state has several reasons: natural disasters, war, marginalization, economic reasons, etc. In our study, we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration processes is a difficult task, due to the lack of data. The reason of the deficiency is that those who leave the country, often forget to report their leaving. From 1 March 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate. Earlier, temporary (more than 3 months settlement was also obligatory to be reported. Many of the leaving Hungarians do not report their leaving, however working abroad for more than 3 months should be reported towards social insurance organizations and tax authorities. I would like to emphasise that my migration potential presentation does not show a direct correlation with the actual migration. However, this study might show the expected movement rates and the composition of emigrants.

  11. Anatomic relationship between left coronary artery and left atrium in patients undergoing atrial fibrillation ablation. (United States)

    Anselmino, Matteo; Torri, Federica; Ferraris, Federico; Calò, Leonardo; Castagno, Davide; Gili, Sebastiano; Rovera, Chiara; Giustetto, Carla; Gaita, Fiorenzo


    Atrial fibrillation transcatheter ablation (TCA) is, within available atrial fibrillation rhythm control strategies, one of the most effective. To potentially improve ablation outcome in case of recurrent atrial fibrillation after a first procedure or in presence of structural myocardial disease, isolation of the pulmonary veins may be associated with extensive lesions within the left atrium. To avoid rare, but potentially life-threatening, complications, thorough knowledge and assessment of left atrium anatomy and its relation to structures in close proximity are, therefore, mandatory. Aim of the present study is to describe, by cardiac computed tomography, the anatomic relationship between aortic root, left coronary artery and left atrium in patients undergoing atrial fibrillation TCA. The cardiac computed tomography scan of 21 patients affected by atrial fibrillation was elaborated to segment left atrium, aortic root and left coronary artery from the surrounding structures and the following distances measured: left atrium and aortic root; left atrium roof and aortic root; left main coronary artery and left atrium; circumflex artery and left atrium appendage; and circumflex artery and mitral valve annulus. Above all, the median distance between left atrium and aortic root (1.9, 1.5-2.1 mm), and between circumflex artery and left atrium appendage ostium (3.0, 2.1-3.4 mm) were minimal (≤3 mm). None of measured distances significantly varied between patients presenting paroxysmal versus persistent atrial fibrillation. The anatomic relationship between left atrium and coronary arteries is extremely relevant when performing atrial fibrillation TCA by extensive lesions. Therefore, at least in the latter case, preablation imaging should be recommended to avoid rare, but potentially life-threatening, complications with the aim of an as well tolerated as possible procedure.

  16. Phenomenology of left-right symmetric dark matter

    International Nuclear Information System (INIS)

    Garcia-Cely, Camilo; Heeck, Julian


    We present a detailed study of dark matter phenomenology in low-scale left-right symmetric models. Stability of new fermion or scalar multiplets is ensured by an accidental matter parity that survives the spontaneous symmetry breaking of the gauge group by scalar triplets. The relic abundance of these particles is set by gauge interactions and gives rise to dark matter candidates with masses above the electroweak scale. Dark matter annihilations are thus modified by the Sommerfeld effect, not only in the early Universe, but also today, for instance, in the Center of the Galaxy. Majorana candidates—triplet, quintuplet, bi-doublet, and bi-triplet—bring only one new parameter to the model, their mass, and are hence highly testable at colliders and through astrophysical observations. Scalar candidates—doublet and 7-plet, the latter being only stable at the renormalizable level—have additional scalar-scalar interactions that give rise to rich phenomenology. The particles under discussion share many features with the well-known candidates wino, Higgsino, inert doublet scalar, sneutrino, and Minimal Dark Matter. In particular, they all predict a large gamma-ray flux from dark matter annihilations, which can be searched for with Cherenkov telescopes. We furthermore discuss models with unequal left-right gauge couplings, g R  ≠ g L , taking the recent experimental hints for a charged gauge boson with 2 TeV mass as a benchmark point. In this case, the dark matter mass is determined by the observed relic density

  17. Early Modern ET, Reflexive Telescopics, and Their Relevance Today (United States)

    Danielson, Dennis

    The period from the discovery of Tycho's New Star in 1572 to Galileo's "geometrization of astronomical space" in 1610 (and the years following) saw the disintegration of the boundary between the sublunary and superlunary spheres—between the "lower storey" and "upper storey" of the Aristotelian Universe. This establishment of a strong physical affinity between the universe "up there" and the earthly realm "down here" was also complemented by the rise of Copernicanism: for once the Earth was seen as a planet, the other planets could readily be imagined as other Earths. This analogy suggested not only physical but also biological affinities and supported the plausibility of humans' capacity to travel to the Moon and beyond. Robert Burton—given the demise of Aristotle's physics—declared in 1621 that "If the heavens be penetrable … it were not amiss in this aerial progress to make wings and fly up." John Wilkins and Francis Godwin in the 1630s actively imagined creatures in the Moon and human journeys thither. The epic poet John Milton in 1667 hinted that "every star [is] perhaps a world / Of destined habitation." Moreover, space travel was no one-way street: Thomas Traherne in the 1670s imagined a dweller among the stars visiting Earth and remarking on what must be the condition of its inhabitants. In these and other ways, seventeenth-century writers offered serious and impressive speculation about extraterrestrial life and its possible perceptions of Earth. Such speculations remain pertinent to astrobiological theory today. What Hans Blumenberg in the 1970s called "reflexive telescopics"—the examination of Earth from an imagined extraterrestrial viewpoint—is an important counterpart to the search for life "out there." It serves as a reminder of the obvious but profound premise that Earth is part of the cosmos. At a popular level we often continue to speak of "outer space" as if the old "two-storey" picture of the universe still had some residual legitimacy

  18. Drilling simulated temporal bones with left-handed tools: a left-hander's right? (United States)

    Torgerson, Cory S; Brydges, Ryan; Chen, Joseph M; Dubrowski, Adam


    Left-handed trainees can be at a disadvantage in the surgical environment because of a right-handed bias. The effectiveness of teaching left-handed trainees to use an otologic drill designed for their dominant hand versus the conventional right-handed drill was examined. Novice medical students were recruited from the university community. Twenty-four subjects were left-handed, and 12 were right-handed. Eight left-handed surgeons also participated. A randomized controlled trial was conducted to compare the performance of left-handed trainees using novel left-handed drills to that of left-handed trainees using right-handed tools and to that of right-handed trainees using right-handed tools. The evaluation consisted of 3 phases: pretest, skill acquisition, and 2 post-tests. The measurement tools included expert assessment of performance, and subjective and objective final product analyses. An initial construct validity phase was conducted in which validity of the assessment tools was ensured. Both the left-handers using left-handed tools and the right-handers using right-handed tools significantly outperformed the left-handers using right-handed tools at pretest, immediate posttest, and delayed posttest. All participants improved their performance as a function of practice. The left-handed trainees learned bone drilling better with tools designed for the left hand. These tools may be incorporated into residency training programs for the development of surgical technical skills. Future studies should assess skill transfer between the left-handed and right-handed drills.

  19. Digestive system fistula: a problem still relevant today. (United States)

    Głuszek, Stanisław; Korczak, Maria; Kot, Marta; Matykiewicz, Jarosław; Kozieł, Dorota


    Digestive system fistula originates most frequently as a complication after surgical procedures, less often occurs in the course of inflammatory diseases, but it can also result from neoplasm and injuries. THE AIM OF THE STUDY was to analyze the causes and retrospectively assess the perioperative procedures as well as the results of digestive system fistula treatment. MATERIAL AND METHODS. Own experience in digestive system fistula treatment was presented. The subject group consisted of 32 patients treated at the General Surgery, Oncology and Endocrinology Clinical Department between 01.05.2005 and 30.04.2010 due to different digestive tract diseases. The causes of the occurrence of digestive system fistula, methods and results of treatment were analyzed. RESULTS. The analysis covered 32 patients with digestive system fistula, among them 15 men and 17 women. Average age for men was 57 years (20-78), and for women 61 years (24-88). In 11 patients idiopathic fistula causally connected with primary inflammatory disease (7 cases) and with neoplasm (4 cases) was diagnosed, in 19 patients fistula was the result of complications after surgery, in 2 - after abdominal cavity injury. Recovery from fistula was achieved in 23 patients (72%) with the use of individually planned conservative therapy (TPN, EN, antibiotics, drainage, and others) and surgery, depending on the needs of individual patient. 5 patients (16%) died, whereas in 4 left (12%) recovery wasn't achieved (fistula in palliative patients, with advanced stages of neoplasm - bronchoesophageal fistula, the recurrence of uterine carcinoma). CONCLUSIONS. Recently the results of digestive system fistula treatment showed an improvement which manifests itself in mortality decrease and shortening of fistula healing time. Yet, digestive system fistula as a serious complication still poses a very difficult surgical problem.

  20. Industrial espionage today and information wars of tomorrow (United States)

    Joyal, Paul


    In this report we review case histories of industrial espionage publicized in the media and in Congressional hearings. The threat to the United Stages as the world's largest investor in R&D is magnified by the transition from a cold war military confrontation of the super powers to an economic competition in global markets. To sustain their market share, France, Japan and Russia have initiated national programs to acquire U.S. technical know-how. Former intelligence staff now distill fragments of sensitive information into meaningful knowledge to guide industrial and national efforts to ascertain dominance. This threat is amplified by the exponential proliferation of global communication networks, like INTERENET, that reach into corporate America and permit unseen adversaries to probe the vast U.S. data stores for unprotected intelligence. Counter intelligence in industrial espionage by the United Stages on a national level is virtually impossible because of public scrutiny in our open society. On the positive side, the upheaval of a rapid transition from high-tension and high economic stability to low-tension and high economic instability is prompting international collaboration against international terrorism. On the corporate level, strategic alliances with foreign firms are expanding to sustain competitiveness and innovation in areas of specialty. A national security plan to protect the U.S. information resources is needed; and a viable policy to operate our information highways as safe conduits for electronic business. The well being of the global economy, not just that of our nation, is at stake and should not be left to chance and provocation.

  1. Mortality-related resource utilization in the inpatient care of hypoplastic left heart syndrome. (United States)

    Danford, David A; Karels, Quentin; Kulkarni, Aparna; Hussain, Aysha; Xiao, Yunbin; Kutty, Shelby


    Quantifying resource utilization in the inpatient care of congenital heart diease is clinically relevant. Our purpose is to measure the investment of inpatient care resources to achieve survival in hypoplastic left heart syndrome (HLHS), and to determine how much of that investment occurs in hospitalizations that have a fatal outcome, the mortality-related resource utilization fraction (MRRUF). A collaborative administrative database, the Pediatric Health Information System (PHIS) containing data for 43 children's hospitals, was queried by primary diagnosis for HLHS admissions of patients ≤21 years old during 2004-2013. Institution, patient age, inpatient deaths, billed charges (BC) and length of stay (LOS) were recorded. In all, 11,122 HLHS admissions were identified which account for total LOS of 277,027 inpatient-days and $3,928,794,660 in BC. There were 1145 inpatient deaths (10.3%). LOS was greater among inpatient deaths than among patients discharged alive (median 17 vs. 12, p providers and consumers that current practices often result in major resource expenditure for inpatient care of HLHS that does not result in survival to hospital dismissal. They highlight the need for data-driven critical review of standard practices to identify patterns of care associated with success, and to modify approaches objectively.

    Plug, B.


    As the millennium approaches, the future of the nuclear power generation appears desolate. Today's nuclear executives are facing challenges resulting from worldwide change and have forced utilities to reevaluate their corporation's future directions. The nuclear industry must be competitive more than ever to address today's rapid changing marketplace and pressures exerted from: regulatory reformation; increased competition; changes in technology; customer evolution; and globalization. These factors have compelled nuclear executives to address questions such as: What impact will these changes have on today's marketplace, and on my corporation? What will characterize tomorrow's successful nuclear facility? How can today's nuclear corporation compete in tomorrow's marketplace? Will my corporation survive? (author)

  3. Left Right Patterning, Evolution and Cardiac Development

    Directory of Open Access Journals (Sweden)

    Iain M. Dykes


    Full Text Available Many aspects of heart development are determined by the left right axis and as a result several congenital diseases have their origins in aberrant left-right patterning. Establishment of this axis occurs early in embryogenesis before formation of the linear heart tube yet impacts upon much later morphogenetic events. In this review I discuss the differing mechanisms by which left-right polarity is achieved in the mouse and chick embryos and comment on the evolution of this system. I then discus three major classes of cardiovascular defect associated with aberrant left-right patterning seen in mouse mutants and human disease. I describe phenotypes associated with the determination of atrial identity and venous connections, looping morphogenesis of the heart tube and finally the asymmetric remodelling of the embryonic branchial arch arterial system to form the leftward looped arch of aorta and associated great arteries. Where appropriate, I consider left right patterning defects from an evolutionary perspective, demonstrating how developmental processes have been modified in species over time and illustrating how comparative embryology can aide in our understanding of congenital heart disease.

    Giridhar A Govindswamy


    Full Text Available Objectives: To assess the number of investigations left behind by patients in radiology department, their cost, and the possible methods of reducing the problem. Materials and Methods: A total of 1424 radiographs, 160 computed tomography (CT scans, 300 ultrasonography (USG reports, and 46 Doppler reports were left behind by patients in one financial year. The total cost of these left behind investigations was calculated and the reports were categorized into normal and abnormal for each modality. Results: Of the radiographs left behind 658 were abnormal, with 211 among these being radiographs of postoperative patients. Thirty-seven percent of CT scans had positive findings. Sixty-eight percent of USG reports had positive findings while 46% of Doppler reports were abnormal. Conclusion: We believe that the cost and number of these left behind investigations over a period of time would definitely be significant for the health care system in a developing country. It is time to think of the possible reasons and methods for containing this problem.

  5. Left atrial laceration with epicardial ligation device. (United States)

    Keating, Vincent P; Kolibash, Christopher P; Khandheria, Bijoy K; Bajwa, Tanvir; Sra, Jasbir; Kress, David C


    Many new devices and techniques are being developed to attempt a reduction in embolic stroke risk for patients with atrial fibrillation who are either unable or unwilling to maintain long-term anticoagulation. One of these new devices (LARIAT®, SentreHEART Inc., Redwood City, California, USA) employs delivery of an epicardial suture to ligate the left atrial appendage after percutaneous pericardial and transseptal access. This series presents three clinical cases that demonstrate a serious and recurrent complication of left atrial laceration and cardiac tamponade shortly following delivery of an epicardial suture ligation to the left atrial appendage. Three clinical cases are described in detail with pre- and postprocedure angiography and echocardiography as well as illustrations reflecting the surgeon's findings on direct visualization of the left atrial lacerations postligation. Potential hypotheses of each injury are examined in light of the case timelines and findings at sternotomy. There was no suggestion that tamponade was related to pericardial or transseptal access, but rather a complication with device delivery. These three patients quickly progressed to clinical cardiac tamponade despite attempted drainage, stressing the importance of cardiovascular surgery backup, including a cardiopulmonary bypass pump, when delivering novel, percutaneous ligation devices for the left atrial appendage.

  7. Deficit or creativity: Cesare Lombroso, Robert Hertz, and the meanings of left-handedness. (United States)

    Kushner, Howard I


    In the first decade of the twentieth century two influential researchers attempted to explain the origin and impact of left-handedness in human history. The first, the Turin physician Cesare Lombroso, often referred to as the father of modern criminology, was nearing the end of his long distinguished career. Lombroso tied left-handedness to criminality, insanity, and feeble mindedness. According to Lombroso, these groups shared biological regressions to primitive mentalities that could not be reversed by education or training. The second, French sociologist Robert Hertz, was at the beginning of a career cut short by his death in combat during the First World War. Hertz challenged Lombroso's claims, insisting that the predominance of right-handedness, whatever its biological substrate, was ultimately a cultural artefact driven by a primitive human urge to make sense of the world by dividing it into binary oppositions in which the right was viewed as sacred and the left as profane. Ending discrimination against left-handedness would, according to Hertz, unleash access to both hands and thus both hemispheres. The results, he insisted, would allow repressed talents and creativity to flourish. The conflicting views of Lombroso and Hertz have informed investigations of the causes and consequences of left-handedness until today. While the language of the debate has been reframed in current scientific discourses, left-handedness continues to be portrayed in the contradictory ways first elaborated by Lombroso and Hertz more than a century ago as either the cause of a variety of learning disabilities or as the key that can unlock creativity and talent. The debate also exposed the extent to which other cultural concerns, particularly anti-Semitism, informed theories of handedness.

  8. The kinds of Ya in today Persian languag

    Directory of Open Access Journals (Sweden)

    S.Mohammadreza Ebnorrasool


    Full Text Available Abstract Diversity of suffix ‘-i’, called ‘ya’, in Persian language, which is of important consideration, for any reason, has not been able to attract scholars and grammarians in the field of Persian language. Here is an attempt to mention different kinds of ‘ya’ and to explain their applications, relying on grammar books, dictionaries, and today native application. The character generally has three types of applications in Persian language. It is firstly one of the Persian alphabet, so it primarily functions as a ‘phoneme’.

  9. Left ventricular performance during psychological stress

    International Nuclear Information System (INIS)

    Young, D.Z.; Massachusetts General Hospital, Boston; Dimsdale, J.E.; Moore, R.H.; Barlai-Kovach, M.; Newell, J.B.; McKusick, K.A.; Boucher, C.A.; Fifer, M.A.; Strauss, H.W.


    Left ventricular ejection fraction, systolic blood pressure and plasma norepinephrine were measured in six normotensive and six mildly hypertensive subjects during rest and psychological stress. Compared with rest, 8 of the 12 subjects developed significant changes in ejection fraction (increase in 6, decrease in 2); 10 of 12 subjects developed significant elevations of plasma norepinephrine; and all developed significant increases in systolic blood pressure. When the stress effects were examined for the total group, as opposed to within subjects, there were significant increases in plasma norepinephrine and systolic blood pressure but, interestingly, mean ejection fraction and stroke volume remained unchanged, implying stress led to increased left ventricular contractility.

    Left-truncation occurs frequently in survival studies, and it is well known how to deal with this for univariate survival times. However, there are few results on how to estimate dependence parameters and regression effects in semiparametric models for clustered survival data with delayed entry....... Surprisingly, existing methods only deal with special cases. In this paper, we clarify different kinds of left-truncation and suggest estimators for semiparametric survival models under specific truncation schemes. The large-sample properties of the estimators are established. Small-sample properties...

    Energy Technology Data Exchange (ETDEWEB)

    Lopez-Negrete, L.; Garcia-Lozano, J.; Sanchez, J. L.; Tejeiro, A.; Sala, J. [Hospital Valle del Nalon. Riano-Sama. Asturias (Spain)


    We report two cases of left paraduodenal internal hernias located in the fossa of Landzert that were diagnosed by CT. Internal hernias are an infrequent cause of acute abdomen, due to the intestinal sub occlusion they produce. Left paraduodenal hernias are responsible for about 50% of internal hernias. CT makes it possible to demonstrate the group of herniated loops between the stomach, fourth segment of the duodenum, descending colon, and tail of the pancreas. The identification of the loops in an atypical position together with displaced blood vessels (mesenteric vessels) and colon gives concerns on them a typical radiological semiology that makes them easily identifiable.

    We propose a possible mechanism for the generation of magnetic fields in negative refraction index composite metamaterials. Considering the propagation of a high-frequency modulated amplitude electric field in a left-handed material (LHM), we show that the ponderomotive interaction between the field and low-frequency potential distributions leads to spontaneous generation of magnetic fields, whose form and properties are discussed

  5. Vergisson 4: a left-handed Neandertal. (United States)

    Condemi, Silvana; Monge, Janet; Quertelet, Sylvain; Frayer, David W; Combier, Jean


    Handedness is an important marker for lateralization of humans in the modern and fossil record. For the most part, Neandertals and their ancestors are strongly right-handed. We describe a single tooth from a Neandertal level at Vergisson 4 (Vg 4-83). This left upper central incisor shows all the features typical of Neandertal incisors. It also exhibits a predominance of left-handed striations. Striations on the incisor's labial surface were mapped at 20x magnification using Photoshop. Angulations of the striations were determined from their deviation from the maximum mesio-distal line and were analyzed using NIH's freeware, Image J. Of the 60 labial surface striations, Vg 4-83 shows a strong predominance of left-handed striations (46; 76.7%), which are statistically significantly different (p handed striations. The identification of another left-handed Neandertal adds to our understanding about handedness variation in this fossil hominin. Given the high frequency of right-handed Neandertals, the 90: 10 modern ratio is still preserved in this group. © 2016 Wiley Periodicals, Inc.

  10. Left-Right Symmetry at LHC

    CERN Document Server

    Maiezza, Alessio; Nesti, Fabrizio; Senjanovic, Goran


    We revisit the issue of the limit on the scale of Left-Right symmetry breaking. We focus on the minimal SU(2)_L x SU(2)_R x U(1)_B-L gauge theory with the seesaw mechanism and discuss the two possibilities of defining Left-Right symmetry as parity or charge conjugation. In the commonly adopted case of parity, we perform a complete numerical study of the quark mass matrices and the associated left and right mixing matrices without any assumptions usually made in the literature about the ratio of vacuum expectation values. We find that the usual lower limit on the mass of the right-handed gauge boson from the K mass difference, M_WR>2.5TeV, is subject to a possible small reduction due to the difference between right and left Cabibbo angles. In the case of charge conjugation the limit on M_WR is somewhat more robust. However, the more severe bounds from CP-violating observables are absent in this case. In fact, the free phases can also resolve the present mild discrepancy between the Standard Model and CP-violat...

  14. Modern Democratic Left and Economic Crisis

    Directory of Open Access Journals (Sweden)

    Dubravko Radošević


    Full Text Available Political left, notably social democracy, implies acceptance of market economy and parliamentary democracy, as a political framework within which the interests of large sections of the population could be preserved. Does the modern political left have a chance to revive, after the global economic crisis? We believe it does. The core idea of social democracy is the idea of equality. It is the growing inequality that could help the return of social democracy. In Croatia, during transition, there was predominantly the process of neoliberalization, and the democratic left accepted a neoliberal economic agenda. Currently Croatia has a structural economic problem and deep recession. Due to the global crisis, the democratic left in Croatia should abandon economic neoliberalism. Macroeconomic policy decision-makers in Croatia should reject orthodox policies, and it is necessary to implement heterodox economic policies. There is an urgent need to achieve a new (postKeynesian consensus, a new combination of post-Keynesian economics and social democracy

  16. Left ventricular function in chronic aortic regurgitation

    International Nuclear Information System (INIS)

    Iskandrian, A.S.; Hakki, A.H.; Manno, B.; Amenta, A.; Kane, S.A.


    Left ventricular performance was determined in 42 patients with moderate or severe aortic regurgitation during upright exercise by measuring left ventricular ejection fraction and volume with radionuclide ventriculography. Classification of the patients according to exercise tolerance showed that patients with normal exercise tolerance (greater than or equal to 7.0 minutes) had a significantly higher ejection fraction at rest (probability [p] . 0.02) and during exercise (p . 0.0002), higher cardiac index at exercise (p . 0.0008) and lower exercise end-systolic volume (p . 0.01) than did patients with limited exercise tolerance. Similar significant differences were noted in younger patients compared with older patients in ejection fraction at rest and exercise (both p . 0.001) and cardiac index at rest (p . 0.03) and exercise (p . 0.0005). The end-diastolic volume decreased during exercise in 60% of the patients. The patients with a decrease in volume were significantly younger and had better exercise tolerance and a larger end-diastolic volume at rest than did patients who showed an increase in volume. The mean corrected left ventricular end-diastolic radius/wall thickness ratio was significantly greater in patients with abnormal than in those with normal exercise reserve (mean +/- standard deviation 476 +/- 146 versus 377 +/- 92 mm Hg, p less than 0.05). Thus, in patients with chronic aortic regurgitation: 1) left ventricular systolic function during exercise was related to age, exercise tolerance and corrected left ventricular end-diastolic radius/wall thickness ratio, and 2) the end-diastolic volume decreased during exercise, especially in younger patients and patients with normal exercise tolerance or a large volume at rest

  17. Observation of alive benthos under a sharp hypoxia and high H2S concentrations inside the microbial mats (methane seeps in the shallows of Black Sea) (United States)

    Gulin, M.


    In 2008 experimental as well as in situ investigations were implemented for studying of vitality and locomotion activity of the micro- and meiobenthos associated with the gas seeps. Research area: near-shore shallow field with the gas seeps, southern sector of Tarkhankut Cape, NW Crimea Peninsula, Black Sea. Cuvette LDO-oxymeter coupled with other sensors and also life-time diagnostics of the organisms including microscopic video filming were used for this case. Concentrations of dissolved methane in the pore space of microbial mats were varied from 27 to 1076 µL/cm3 (220 on average). Content of organic matter of the uppermost seep mats was approximately in 50 times higher than at the background stations. Probably, such enrichments is attractive for benthic organisms. At the same time, H2S-pollution of seep microbiotope environment is detected as critical (Eh = -400/-460 mV). Near to the gas seeps alive and active Polychaeta, Nematoda, Harpacticoida and Ciliata were found. It is important, that anoxia-adapted organisms of the last two groups were quickly died at contact with air.

  18. Assessment of stiffness of the hypertrophied left ventricle of bicyclists using left ventricular inflow Doppler velocimetry. (United States)

    Fagard, R; Van den Broeke, C; Bielen, E; Vanhees, L; Amery, A


    Sixteen male bicyclists and 16 control subjects were studied to assess whether the left ventricular hypertrophy of athletes is associated with changes in diastolic left ventricular function. The cyclists had a larger left ventricular internal diameter on echocardiography (55.2 versus 47.9 mm; p less than 0.001) and a disproportionate increase in wall thickness relative to the internal diameter (0.48 versus 0.41; p less than 0.01), indicating a mixed eccentric-concentric type of hypertrophy. Left ventricular inflow Doppler velocimetry showed similar results in athletes and control subjects for peak flow velocities in the atrial contraction phase (30 versus 32 cm/s; p = NS) and in the early diastolic rapid filling phase (71 versus 67 cm/s; p = NS). The similar ratio of both velocities, that is, 0.43 in the cyclists and 0.49 in the control subjects, suggests that left ventricular distensibility is unaltered in cyclists. It is concluded that the left ventricular hypertrophy observed in cyclists is not associated with changes in ventricular stiffness, as estimated from left ventricular inflow Doppler velocimetry.

    A 70-year-old man with a 3-year history of bronchiectasis presented with massive hemoptysis that had lasted for 3 days. In our attempt to perform bronchial artery embolization, upper abdominal angiography was required to locate the left bronchial artery, which in this case was of anomalous origin, arising from a replaced left hepatic artery, which arose from the left gastric artery-a very unusual anatomical variant. We performed embolization with polyvinyl alcohol particles, and the patient's symptoms resolved completely, with no additional complications after conservative treatment.

  1. Dyscalculia, dysgraphia, and left-right confusion from a left posterior peri-insular infarct. (United States)

    Bhattacharyya, S; Cai, X; Klein, J P


    The Gerstmann syndrome of dyscalculia, dysgraphia, left-right confusion, and finger agnosia is generally attributed to lesions near the angular gyrus of the dominant hemisphere. A 68-year-old right-handed woman presented with sudden difficulty completing a Sudoku grid and was found to have dyscalculia, dysgraphia, and left-right confusion. Magnetic resonance imaging (MRI) showed a focus of abnormal reduced diffusivity in the left posterior insula and temporoparietal operculum consistent with acute infarct. Gerstmann syndrome from an insular or peri-insular lesion has not been described in the literature previously. Pathological and functional imaging studies show connections between left posterior insular region and inferior parietal lobe. We postulate that the insula and operculum lesion disrupted key functional networks resulting in a pseudoparietal presentation.

  3. Left ventricular non-compaction cardiomyopathy and left ventricular assist device: a word of caution. (United States)

    Kornberger, A; Stock, U A; Risteski, P; Beiras Fernandez, A


    In patients with left ventricular non-compaction (LVNC), implantation of a left ventricular assist device (LVAD) may be performed as a bridge to transplantation. In this respect, the particular characteristics of the left ventricular myocardium may represent a challenge. We report a patient with LVNC who required urgent heart transplantation for inflow cannula obstruction nine months after receiving a LVAD. LVAD parameters, echocardiography and examination of the explanted heart suggested changes of left ventricular configuration brought about by LVAD support as the most likely cause of inflow cannula obstruction. We conclude that changes experienced by non-compacted myocardium during LVAD support may give rise to inflow cannula obstruction and flow reduction. Presence of LVNC mandates tight surveillance for changes in LV configuration and LVAD flow characteristics and may justify urgent transplantation listing status.

  4. [Left postpneumonectomy syndrome: early endoscopic treatment]. (United States)

    Rombolá, Carlos A; León Atance, Pablo; Honguero Martínez, Antonio Francisco; Rueda Martínez, Juan Luis; Núñez Ares, Ana; Vizcaya Sánchez, Manuel


    Postpneumonectomy syndrome is characterized by postoperative bronchial obstruction caused by mediastinal shift. The syndrome is well documented in the medical literature as a late complication of right pneumonectomy; however, it rarely occurs following resection of the left lung, and only 10 cases have been published. The pathophysiology, clinical manifestations, prognosis, and treatment are similar for both sides of the lung. We present the case of an adult patient who underwent left pneumonectomy and developed postpneumonectomy syndrome 15 months later. Stenosis of the intermediate bronchus occurred between the vertebral body and the right pulmonary artery. Endoscopic treatment with a self-expanding metal stent was successful, and complete remission was observed over the 6 months of follow-up.

    We present a critical analysis of the spontaneous symmetry breaking and the Higgs sector of the conventional SU(2) L circle-times SU(2) R circle-times U(1) B-L left-right symmetric theory involving bi-doublet and triplet Higgs fields. We examine the phenomenological constraints imposed on the minimization of the Higgs potential arising from experimental observations, and explore the resulting consequences including the problem of ''fine- tuning'' arising from the hierarchy of mass scales involved. We show that it is non-trivial to satisfy all of these constraints. We contrast the benefits of this general class left-right models against the required ''fine-tuning'' necessary to force the phenomenology to conform to experimental fact. 17 refs., 1 fig

  6. Minimal Left-Right Symmetric Dark Matter. (United States)

    Heeck, Julian; Patra, Sudhanwa


    We show that left-right symmetric models can easily accommodate stable TeV-scale dark matter particles without the need for an ad hoc stabilizing symmetry. The stability of a newly introduced multiplet either arises accidentally as in the minimal dark matter framework or comes courtesy of the remaining unbroken Z_{2} subgroup of B-L. Only one new parameter is introduced: the mass of the new multiplet. As minimal examples, we study left-right fermion triplets and quintuplets and show that they can form viable two-component dark matter. This approach is, in particular, valid for SU(2)×SU(2)×U(1) models that explain the recent diboson excess at ATLAS in terms of a new charged gauge boson of mass 2 TeV.

    Left ventricular noncompaction (LVNC) may result in systolic left ventricular (LV) failure resulting in the need for heart transplantation. LV assist devices (LVAD) have been used to bridge these patients to transplantation; however, the extensive trabeculations found in these patients predispose them to thromboembolic events and pump thrombosis. We describe a patient with LVNC in whom an aggressive surgical approach was used to debride the LV cavity of trabeculations to successfully implant an LVAD. © 2017 Wiley Periodicals, Inc.

The hemodynamic abnormalities seen in PH-LHD are complex, and there are currently minimal evidence-based recommendations for the management of PH-LHD. While it is accepted that PH in the context of left heart disease is a marker of worse prognosis, it remains unclear whether its primary treatment is beneficial or harmful. In this article, we discuss the prevalence and significance of PH in patients with heart failure (HF) with reduced ejection fraction (HFrEF) as well as HF with preserved ejection fraction (HFpEF), and those with valvular heart disease and provide insights into the complex pathophysiology of cardiopulmonary interrelationship in individuals with PH due to left heart disease. Furthermore, we provide a framework for diagnostic testing and an approach to optimal management of these complex patients based on current European Society of Cardiology (ESC) guidelines.

  13. Anomalous Origin of Left Circumflex Artery (United States)

    Çitaku, Hajdin; Kamberi, Lulzim; Gorani, Daut; Koçinaj, Dardan; Krasniqi, Xhevdet


    Introduction: The coronary anatomic variation of the left circumflex artery (LCx) is considered as the most common anatomic variation with a separate ostium from the right sinus, and very unusual variation as a proximal branch of right coronary artery (RCA). Case report: We report two cases, the first case is a 64-year-old man with chest pain and with history of hypertension, obesity, dyslipidemia and current smoker, and the second case is a 67-year-old who presented to the emergency department with chest pain and with a past medical history of arterial hypertension and type 2 diabetes mellitus. In the coronarography of the first case is detected an ectopic left circumflex coronary artery from the right coronary sinus with stenotic changes in RCA and LCx. The second case in the coronary angiography revealed an ectopic left circumflex coronary artery from the proximal part of the right coronary artery with stenotic changes in LAD, RCA and LCx. Based on guidelines for revascularization our patients successfully underwent treatment procedures. We present two cases that because of the atherosclerotic coronary artery disease leads to the need of coronarography find out the presence of coronary artery anomalies. Conclusion: During the coronarography we should think about coronary artery anomaly or missing artery knowing that type of these anomalies, considering that may be a contributing factor in the development of the atherosclerosis determines the method of the treatment.

  14. Pulmonary hypertension due to left heart disease. (United States)

    Berthelot, Emmanuelle; Bailly, Minh Tam; Hatimi, Safwane El; Robard, Ingrid; Rezgui, Hatem; Bouchachi, Amir; Montani, David; Sitbon, Olivier; Chemla, Denis; Assayag, Patrick

    Pulmonary hypertension due to left heart disease, also known as group 2 pulmonary hypertension according to the European Society of Cardiology/European Respiratory Society classification, is the most common cause of pulmonary hypertension. In patients with left heart disease, the development of pulmonary hypertension favours right heart dysfunction, which has a major impact on disease severity and outcome. Over the past few years, this condition has been considered more frequently. However, epidemiological studies of group 2 pulmonary hypertension are less exhaustive than studies of other causes of pulmonary hypertension. In group 2 patients, pulmonary hypertension may be caused by an isolated increase in left-sided filling pressures or by a combination of this condition with increased pulmonary vascular resistance, with an abnormally high pressure gradient between arteries and pulmonary veins. A better understanding of the conditions underlying pulmonary hypertension is of key importance to establish a comprehensive diagnosis, leading to an adapted treatment to reduce heart failure morbidity and mortality. In this review, epidemiology, mechanisms and diagnostic approaches are reviewed; then, treatment options and future approaches are considered. Copyright © 2017. Published by Elsevier Masson SAS.

  15. Stationarity: Wanted dead or alive? (United States)

    Lins, Larry F.; Cohn, Timothy A.


    Aligning engineering practice with natural process behavior would appear, on its face, to be a prudent and reasonable course of action. However, if we do not understand the long-term characteristics of hydroclimatic processes, how does one find the prudent and reasonable course needed for water management? We consider this question in light of three aspects of existing and unresolved issues affecting hydroclimatic variability and statistical inference: Hurst-Kolmogorov phenomena; the complications long-term persistence introduces with respect to statistical understanding; and the dependence of process understanding on arbitrary sampling choices. These problems are not easily addressed. In such circumstances, humility may be more important than physics; a simple model with well-understood flaws may be preferable to a sophisticated model whose correspondence to reality is uncertain.

    Full Text Available Reading Comprehension has been determined (by the Director of First Common Year Program to be one of the core subjects for the first year IPB students, either in semester one or two. With the objective of being able to read English texts effectively and efficiently, the teaching of reading for these undergraduate programs are basically confined to skills that can develop reading speed and improve students‘ comprehension and reasoning abilities. Thus, skills like finding both general and specific ideas, guessing unknown words, finding meanings from English-English dictionary, predicting, ad nfinding inferences are those need to be covered. Such kind of teaching, however, can sometimes become a demanding task when dealing with certain classroom conditions and with certain targets. It is, therefore, a challenge for all English teachers in my university to be able to carry out the task well so as to achieve the above teaching objectives. Meanwhile, students‘ evaluation reveals that 3 semesters ago, teachers obtained various scores in their teaching evaluation, ranging from 2 to 3.7 out of the 1-4 scale. This paper, accordingly, is written to find out the teaching method and strategies used by those obtaining relatively good scores (3.2 and above in order to disseminate them as better insights for the teaching of reading not only in my university but also other schools or colleges.

    Evaluation of: Tabár L, Vitak B, Chen TH et al. Swedish Two-County Trial: impact of mammographic screening on breast cancer mortality during 3 decades. Radiology 260(3), 658-663 (2011). In the 1980s, the periodic invitation of women aged 40-69 years for mammographic screening in the Swedish Two-County Trial showed a strong 30% reduction in breast cancer mortality. The result of 2-3-yearly mammographic examinations has persisted throughout the long follow-up of three decades. Through the richness of the collected and verified data, the trial has also demonstrated a substantial and absolute reduction in mortality risk. For each 414 women screened for 7 years (approximately four screening examinations), one breast cancer death was prevented. Transferring these outcomes to, for example, the national program of the UK, for every 1000 women aged 47-73 years attending the 3-yearly screenings (nine screening examinations) at least five to seven breast cancer deaths would be prevented. In recent follow-up papers by the Swedish trial group, the major human cost of screening (false-positive outcome, occurrence of interval cancer, overdiagnosis and radiation exposure) were judged to be in balance with the accurately demonstrated mortality benefit.

  2. Left-Deviating Prism Adaptation in Left Neglect Patient: Reflexions on a Negative Result

    Directory of Open Access Journals (Sweden)

    Jacques Luauté


    Full Text Available Adaptation to right-deviating prisms is a promising intervention for the rehabilitation of patients with left spatial neglect. In order to test the lateral specificity of prism adaptation on left neglect, the present study evaluated the effect of left-deviating prism on straight-ahead pointing movements and on several classical neuropsychological tests in a group of five right brain-damaged patients with left spatial neglect. A group of healthy subjects was also included for comparison purposes. After a single session of exposing simple manual pointing to left-deviating prisms, contrary to healthy controls, none of the patients showed a reliable change of the straight-ahead pointing movement in the dark. No significant modification of attentional paper-and-pencil tasks was either observed immediately or 2 hours after prism adaptation. These results suggest that the therapeutic effect of prism adaptation on left spatial neglect relies on a specific lateralized mechanism. Evidence for a directional effect for prism adaptation both in terms of the side of the visuomanual adaptation and therefore possibly in terms of the side of brain affected by the stimulation is discussed.

  3. Ipsilesional deficit of selective attention in left homonymous hemianopia and left unilateral spatial neglect. (United States)

    Chokron, Sylvie; Peyrin, Carole; Perez, Céline


    Patients with homonymous hemianopia may present a subtle ipsilesional deficit, recently referred to as 'sightblindness' in addition to the contralesional visual field defect. We recently demonstrated that this deficit could be worse in right brain-damaged patients with left hemianopia than in left brain-damaged patients with right hemianopia, confirming right hemisphere dominance for visuo-spatial and attentional capacities. In the present study we investigate whether this ipsilesional deficit could be attentional in nature and to what extent it is comparable in right brain-damaged (RBD) patients with left hemianopia and in RBD patients with left neglect. The study was also conducted in RBD patients with neither left hemianopia nor left neglect signs in order to test if a right hemisphere lesion per se could be responsible for subtle ipsilesional attentional deficit. To reach this aim, we tested selective attentional capacities in both visual fields of 10 right brain-damaged patients with left neglect (LN), 8 right brain-damaged patients with left homonymous hemianopia (LHH), 8 right brain-damaged patients with no signs of left neglect or left hemianopia (RBD controls), and 17 healthy age-matched participants (Normal controls). A lateralized letter-detection task was used to test if right-brain damaged patients with LN or LH may present a deficit of selective attention in their right, ipsilesional visual field, in comparison to Normal and RBD controls. Participants were asked to detect a target letter in either a single large stimulus (low attentional load) or a small stimulus surrounded by flankers (high attentional load). Stimuli were displayed either in the left or in the right visual field. Accuracy and reaction times were recorded. Results on accuracy showed that both LN and LH patients exhibited lower correct responses than Normal controls in their ipsilesional right visual field, suggesting an attentional deficit in their ipsilesional, supposed healthy

  7. Science in the Making: Right Hand, Left Hand. III: Estimating historical rates of left-handedness. (United States)

    McManus, I C; Moore, James; Freegard, Matthew; Rawles, Richard


    The BBC television programme Right Hand, Left Hand, broadcast in August 1953, used a postal questionnaire to ask viewers about their handedness. Respondents were born between 1864 and 1948, and in principle therefore the study provides information on rates of left-handedness in those born in the nineteenth century, a group for which few data are otherwise available. A total of 6,549 responses were received, with an overall rate of left-handedness of 15.2%, which is substantially above that expected for a cohort born in the nineteenth and early twentieth centuries. Left-handers are likely to respond preferentially to surveys about handedness, and the extent of over-response can be estimated in modern control data obtained from a handedness website, from the 1953 BBC data, and from Crichton-Browne's 1907 survey, in which there was also a response bias. Response bias appears to have been growing, being relatively greater in the most modern studies. In the 1953 data there is also evidence that left-handers were more common among later rather than early responders, suggesting that left-handers may have been specifically recruited into the study, perhaps by other left-handers who had responded earlier. In the present study the estimated rate of bias was used to correct the nineteenth-century BBC data, which was then combined with other available data as a mixture of two constrained Weibull functions, to obtain an overall estimate of handedness rates in the nineteenth century. The best estimates are that left-handedness was at its nadir of about 3% for those born between about 1880 and 1900. Extrapolating backwards, the rate of left-handedness in the eighteenth century was probably about 10%, with the decline beginning in about 1780, and reaching around 7% in about 1830, although inevitably there are many uncertainties in those estimates. What does seem indisputable is that rates of left-handedness fell during most of the nineteenth century, only subsequently to rise in

    The final part of this series attempts to evaluate the relevance of Nazi medicine for doctors today. Euthanasia, informed consent, the conflict of interests of the individual versus those of society and racism were as prominent themes of Nazi medicine as they are today. It would be foolish not to learn from experiences of the past. Nazi medicine can therefore never be an irrelevant subject of the days gone by.

    There is a growing perception that the left handed (LH) medical students are facing difficulties while performing the clinical tasks that involve psychomotor skill, although the evidence is very limited and diverse. The present study aimed to evaluate the clinical psychomotor skills among Right-handed (RH) and left-handed (LH) medical students. For this study, 54 (27 left handed and 27 right handed) first year medical students were selected. They were trained for different clinical psychomotor skills including suturing, laparoscopy, intravenous cannulation and urinary catheterization under the supervision of certified instructors. All students were evaluated for psychomotor skills by different instructors. The comparative performance of the students was measured by using a global rating scale, each selected criteria was allotted 5-points score with the total score of 25. There were no significant differences in the performance of psychomotor skills among LH and RH medical students. The global rating score obtained by medical students in suturing techniques was: LH 15.89 ± 2.88, RH 16.15 ± 2.75 (p = 0.737), cannulation techniques LH 20.44 ± 2.81, RH 20.70 ± 2.56 (p = 0.725), urinary catheterization LH 4.33 ± 0.96 RH 4.11 ± 1.05 (p = 0.421). For laparoscopic skills total peg transfer time was shorter among LH medical students compared to RH medical students (LH 129.85 ± 80.87 s vs RH 135.52 ± 104.81 s) (p = 0.825). However, both RH and LH students completed their procedure within the stipulated time. Among LH and RH medical students no significant difference was observed in performing the common surgical psychomotor skills. Surgical skills for LH or RH might not be a result of innate dexterity but rather the academic environment in which they are trained and assessed. Early laterality-related mentoring in medical schools as well as during the clinical residency might reduce the inconveniences faced by the left

  11. The New Left in the European Democracies: The Case of the German Radical Left

    Directory of Open Access Journals (Sweden)

    Marco Damiani


    Full Text Available The new form of the social and political conflict cannot be explained by the traditional categories of right and left, but it articulates to them on two plans, that of the establishment, intended like plan of the structured political conflict from the traditional actors, and that of the anti-establishment, in which new representations of politics emerge. The New Left is characterized by type of intermittent participation and new perspectives on mobilization inside the parties and the social movements. This type of parties differs moreover from the traditional ones left of the socialist and social democratic left in not arranging of organizations collaterals placed under the direction of the leadership of the same party. The mobilization that spontaneously assumes not conventional forms of active participation of the citizens, or is primed by the action of an associative network of which the same parties take part, than however does not monopo-lize the collective action. In this regard, the attention will be dedicated to the study of Die Linke: an anti-establishment party of the non-socialist German left-wing, heir to the communist tradition. The choice was affected to the German model because: 1 Germany is a country with a strong social democratic tradition, but 25 years after the fall of the Berlin Wall the German political system identifies a new antagonist political party; 2 Die Linke represents an interesting case in the political landscape of the European radical left because is a one-party that gives up at the federation of parties to try to unify the political parties of German radical left-wing.

  12. Teaching Medieval Music Today: New Approaches to Paleography and Music History

    Directory of Open Access Journals (Sweden)

    Cesarino Ruini


    Full Text Available Besides a tendency to abstractness, inherent in the technical nature of the subject itself, a common problem in the teaching of medieval music history is how to awaken the interest of learners in matters that are so far back in time as to have nothing in common with modern sensibility. Referring to the introduction of the staff by Guido of Arezzo in the 11th century, the article tries to explain how, by aptly combining chronologically organized descriptions of facts with a basic study of documents (that is, by adopting the rudiments of the research methods used by expert historians, students can be encouraged to reconstruct history with a strict method. This approach also sheds light on the reasons why men and women of the past adopted certain innovations or kept certain traditions alive.

    Directory of Open Access Journals (Sweden)

    Fabrizio Gambini


    Full Text Available The conception of psychiatry in neuroscience is a blind alley that leads to the loss of all that is human beyond diagnostic calcification and the designation of behaviour. On the other hand, psychoanalysis has failed in its potential for giving new life to psychiatry, and has created a false dichotomy between scientific blindness and fictional speculation. The article offers no third way but rather offers an interpretation of Freud and Lacan that entails a solid conception of language, and one that respects and accounts for the variables in subjective expressions through which all human expressiveness is necessarily made manifest. This means it is essential for psychoanalysis to interact with philosophy and, in particular, with so‐called negative philosophies.

  17. Doctors Today

    LENUS (Irish Health Repository)

    Murphy, JFA


    Doctors’ relationship with patients and their role in society is changing. Until the 1960s doctors concentrated on the welfare of patients with less emphasis placed on patients’ rights1. Over recent decades there has been increasing empowerment of the individual across all facets of society including health care. Doctors continue to be perceived as having expertise and authority over medical science. Patients, however, now hold sway over questions of values or preferences. We all must be aware of this change in the doctor- patient interaction. We need to be more aware of the outcomes that patients view as important. The concept of shared decision-making with the patient is now widely appreciated. The process involves a change in mind set particularly for doctors who trained in an earlier era.

    Graham-Smith, F.


    The theory concerning pulsars is reviewed, with particular attention to possible evolution, life cycle, and rejuvenation of these bodies. Quantum liquids, such as neutron superfluids, and evidence for the existence of superfluid vortices and other internal phenomena are considered with particular attention to the Crab pulsar. Rate of change of the rotation rate is measured and analyzed for the Crab pulsar and the implications of deviations in the pulse times from those of a perfect rotator are examined. Glitches, the sudden increase in rotation rate of a pulsar that has previously exhibited a steady slowdown, are discussed and it is suggested that the movement of the superfluid core relative to the crust is responsible for this phenomenon. It is noted that radio waves from pulsars can be used to determine the intensity and structure of interplanetary and interstellar gas turbulence and to provide a direct measure of the strength of the interstellar magnetic field

  6. Left atrio-vertebral ratio: A new computed-tomography measurement to identify left atrial dilation. (United States)

    Baque-Juston, Marie; Volondat, Manuelle; Fontas, Eric; Roger, Coralie; Brunner, Philippe; Padovani, Bernard; Chevallier, Patrick


    Left cardiac chambers dilation, interstitial lung changes and pleural effusions are the characteristics of cardiogenic pulmonary oedema on computed tomography (CT) of the chest but mensuration of the left atrial size is not routinely performed. Cardiac chambers normal dimensions are known to be proportional to the patient's build and anthropomorphic data but adjustment of chambers dimensions to available elements seen on the axial CT images has never been evaluated before. Our objective was to use data easily available on axial images to directly scale the left atrium. We chose to divide the left atrial diameter by the thoracic vertebral diameter, using the latter as a body-mass indicator. As a preliminary study, we aimed to evaluate the range of values of this left atrio-vertebral ratio (LAVR) by comparing patients suffering from cardiogenic pulmonary oedema with patients free of cardiac disease. We hypothesized that if the difference of values in these two populations of patients was significant enough, this ratio would be relevant and could be used as a quick criterion in different clinical situations. Two radiologists reviewed CT scans of 32 of patients free of cardiac disease and 40 patients in acute cardiac failure. The maximum diameter of the left atrium at the level of the right inferior pulmonary vein was divided by the vertebral transverse diameter to generate a left atrio-vertebral ratio. Receiver operating characteristic curves identified the threshold associated with pulmonary oedema. The mean LAVR was 1.85 ± 0.27 in asymptomatic patients and 2.48 ± 0.35 in patients with pulmonary oedema. A LAVR of 2.1 yielded 85% sensitivity and 88% specificity for the diagnosis of cardiogenic pulmonary oedema. LAVR is a simple new measure directly scaling the left atrial diameter to the anthropomorphic characteristics of the patient. In our series, a ratio above 2.1 is strongly associated with cardiogenic pulmonary oedema indirectly suggesting left atrial dilation

  7. Left ventricular heart failure and pulmonary hypertension† (United States)

    Rosenkranz, Stephan; Gibbs, J. Simon R.; Wachter, Rolf; De Marco, Teresa; Vonk-Noordegraaf, Anton; Vachiéry, Jean-Luc


    Abstract In patients with left ventricular heart failure (HF), the development of pulmonary hypertension (PH) and right ventricular (RV) dysfunction are frequent and have important impact on disease progression, morbidity, and mortality, and therefore warrant clinical attention. Pulmonary hypertension related to left heart disease (LHD) by far represents the most common form of PH, accounting for 65–80% of cases. The proper distinction between pulmonary arterial hypertension and PH-LHD may be challenging, yet it has direct therapeutic consequences. Despite recent advances in the pathophysiological understanding and clinical assessment, and adjustments in the haemodynamic definitions and classification of PH-LHD, the haemodynamic interrelations in combined post- and pre-capillary PH are complex, definitions and prognostic significance of haemodynamic variables characterizing the degree of pre-capillary PH in LHD remain suboptimal, and there are currently no evidence-based recommendations for the management of PH-LHD. Here, we highlight the prevalence and significance of PH and RV dysfunction in patients with both HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF), and provide insights into the complex pathophysiology of cardiopulmonary interaction in LHD, which may lead to the evolution from a ‘left ventricular phenotype’ to a ‘right ventricular phenotype’ across the natural history of HF. Furthermore, we propose to better define the individual phenotype of PH by integrating the clinical context, non-invasive assessment, and invasive haemodynamic variables in a structured diagnostic work-up. Finally, we challenge current definitions and diagnostic short falls, and discuss gaps in evidence, therapeutic options and the necessity for future developments in this context. PMID:26508169

A middle-aged female with a positive family history of coronary disease was admitted with chest pain, electrocardiography (ECG changes in the area of the inferolateral wall and elevation in cardiac specific enzymes. Initially, she was suspected of having acute coronary syndrome. However, in the left ventricular apex, especially alongside the lateral and inferior walls, cardiac ultrasound visualised hypertrabeculation with multiple trabeculae projecting inside the left ventricular cavity. A short-axis view of the heart above the papillary muscles revealed the presence of two layers of the myocardium: a compacted homogeneous layer adjacent to the epicardium and a spongy layer with trabeculae and sinusoids under the endocardium. The thickness ratio between the two layers was 2.2:1. The same abnormalities were corroborated by multislice computed tomography (MSCT of the heart. Conclusion. Left ventricular noncompaction is a rare, usually hereditary cardiomyopathy, which should be considered as a possibility in patients with myocardial hypertrophy. It is very often mistaken for coronary disease owing to ECG changes and elevated cardiac specific enzymes associated with myocardial hypertrophy and heart failure.

  9. Doubling left syntactic positions in Danish

    DEFF Research Database (Denmark)

    Jørgensen, Henrik


    This paper deals with the doubling of left syntactic positions in Danish. Such doublings consist of a referential element: a NP or a clause, and an anaphoric element, an unstressed personal pronoun or an unstressed resumptive adverb. In main clauses, the CP-spec position may double in this way, w...... in the analysis of a broadcasted public speech (sect. 5). In earlier versions of Danish, as shown in sect. 4, the construction is both more frequent in writing and also seems almost obligatory....

  10. Mycobacterium chimaera left ventricular assist device infections. (United States)

    Balsam, Leora B; Louie, Eddie; Hill, Fred; Levine, Jamie; Phillips, Michael S


    A global outbreak of invasive Mycobacterium chimaera infections after cardiac surgery has recently been linked to bioaerosols from contaminated heater-cooler units. The majority of cases have occurred after valvular surgery or aortic graft surgery and nearly half have resulted in death. To date, infections in patients with left ventricular assist devices (LVADs) have not been characterized in the literature. We report two cases of device-associated M. chimaera infection in patients with continuous-flow LVADs and describe challenges related to diagnosis and management in this population. © 2017 Wiley Periodicals, Inc.

  12. Multiple Coronary Artery Microfistulas Associated with Apical Hypertrophic Cardiomyopathy: Left and Right Coronary Artery to the Left Ventricle

    Directory of Open Access Journals (Sweden)

    Jeong-Woo Choi


    Full Text Available A 76-year-old woman underwent coronary angiography for chest pain. On the coronary angiogram, no significant coronary artery atherosclerotic stenosis was observed. Multiple coronary artery microfistulas, draining from the left anterior descending artery to the left ventricle and from the posterior descending artery of the right coronary artery to the left ventricle, were observed. Apical wall thickening and fistula flow from the left anterior descending artery were demonstrated by using transthoracic echocardiography. We describe a rare case of multiple coronary artery microfistulas from the left and right coronary artery to the left ventricle combined with apical hypertrophic cardiomyopathy.

  13. Heart Failure with Transient Left Bundle Branch Block in the Setting of Left Coronary Fistula

    Directory of Open Access Journals (Sweden)

    Stephen P. Juraschek


    Full Text Available Coronary arterial fistulas are rare communications between vessels or chambers of the heart. Although cardiac symptoms associated with fistulas are well described, fistulas are seldom considered in the differential diagnosis of acute myocardial ischemia. We describe the case of a 64-year-old man who presented with left shoulder pain, signs of heart failure, and a new left bundle branch block (LBBB. Cardiac catheterization revealed a small left anterior descending (LAD-to-pulmonary artery (PA fistula. Diuresis led to subjective improvement of the patient's symptoms and within several days the LBBB resolved. We hypothesize that the coronary fistula in this patient contributed to transient ischemia of the LAD territory through a coronary steal mechanism. We elected to observe rather than repair the fistula, as his symptoms and ECG changes resolved with treatment of his heart failure.

  14. Nonlinear left-handed transmission line metamaterials

    International Nuclear Information System (INIS)

    Kozyrev, A B; Weide, D W van der


    Metamaterials, exhibiting simultaneously negative permittivity ε and permeability μ, more commonly referred to as left-handed metamaterials (LHMs) and also known as negative-index materials, have received substantial attention in the scientific and engineering communities [1]. Most studies of LHMs (and electromagnetic metamaterials in general) have been in the linear regime of wave propagation and have already inspired new types of microwave circuits and devices. The results of these studies have already been the subject of numerous reviews and books. This review covers a less explored but rapidly developing area of investigation involving media that combine nonlinearity (dependence of the permittivity and permeability on the magnitude of the propagating field) with the anomalous dispersion exhibited by LHM. The nonlinear phenomena in such media will be considered on the example of a model system: the nonlinear left-handed transmission line. These nonlinear phenomena include parametric generation and amplification, harmonic and subharmonic generation as well as modulational instabilities and envelope solitons. (topical review)

  15. Emission computer tomography of the left ventricle

    Energy Technology Data Exchange (ETDEWEB)

    Semmler, W.; Felix, R.; Calder, D.; Golde, G.; Botsch, H.


    Tomographic studies and time-dependent tomograms on phantoms and patients were carried out using a 7-pinhole collimator in order to study the clinical value of ECG-triggered tomographic radionuclid ventriculography. A suitable computer programme has been developed. The results have shown that it is possible to evaluate local contraction abnormalities by this method. Using a left oblique position of the collimator (LAO (45/sup 0/) - cranial (15/sup 0/)), emission computer tomography is aligned with the longitudinal axis for the heart. In this way, a single projection is sufficient to show the montility of the anterior and posterior walls and of the septum. Hypokinesis, akinesis or dyskinesis can be recognised visually. The localisation and extent of the defect can be determined through the 7-pinhole collimator. Reconstructed images of the triggered radionuclide scintigrams show excellent marginal definition. In the RAO projection the left ventricle can be seen without superimposition and images obtained which equal those of a first-pass technique.

  16. Left hepatectomy after right paramedian sectoriectomy. (United States)

    Takamoto, Takeshi; Hashimoto, Takuya; Makuuchi, Masatoshi


    Repeat hepatectomy is beneficial for selected patients with recurrence of liver malignancies. However, the operative procedure becomes technically demanding when the previous hepatectomy was complex, with hepatic veins and stump of portal pedicles exposed on the liver transection surface. We performed left hepatectomy after right paramedian sectoriectomy (RPMS) for three patients. Here, we describe our surgical technique and the postoperative outcomes achieved. This procedure allowed for safe adhesiolysis between the middle and right hepatic veins by following a fibrous plane. The mean operative time was 8.7 h, including 4.9 h of adhesiolysis. The mean remnant liver volume (right lateral sector and the caudate lobe) was calculated as 704 ml, being 62% of total liver volume. There was no postoperative liver failure or mortality. In conclusion, left hepatectomy after RPMS is a feasible procedure for patients with sufficient remnant liver volume, even though the middle and right hepatic veins run side by side after liver regeneration.

    Full Text Available Total anomalous systemic venous connection (TASVC to the left atrium (LA is a rare congenital anomaly. An 11-year-old girl presented with complaints of palpitations and cyanosis. TASVC with left isomerism and noncompaction of LV was diagnosed after contrast echocardiogram and computed tomography angiogram. The knowledge of anatomy and pathophysiology is essential for the successful management of these cases. Anesthetic concerns in this case were polycythemia, paradoxical embolism and rhythm abnormalities. The patient was successfully operated by rerouting the systemic venous connection to the right atrium.

  11. Surgery of secondary mitral insufficiency in patients with impaired left ventricular function

    Directory of Open Access Journals (Sweden)

    Weber Raluca


    Full Text Available Abstract Background Secondary mitral insufficiency (SMI is an indicator of a poor prognosis in patients with ischemic and dilated cardiomyopathies. Numerous studies corroborated that mitral valve (MV surgery improves survival and may be an alternative to heart transplantation in this group of patients. The aim of the study was to retrospectively analyze the early and mid-term clinical results after MV repair resp. replacement in patients with moderate-severe to severe SMI and left ventricular ejection fraction (LVEF below 35%. Methods We investigated 40 patients with poor LVEF (mean, 28 ± 5% and SMI who underwent MV repair (n = 26 resp. replacement (n = 14 at the University Hospital Muenster from January 1994 to December 2005. All patients were on maximized heart failure medication. 6 pts. had prior coronary artery bypass grafts (CABG. Twenty-seven patients were in New York Heart Association (NYHA class III and 13 were in class IV. Eight patients were initially considered for transplantation. During the operation, 14 pts had CABG for incidental disease and 8 had tricuspid valve repair. Follow-up included echocardiography, ECG, and physician's examination and was completed in 90% among survivors. Additionally, the late results were compared with the survival after orthotope heart transplantation (oHTX in adults with ischemic or dilated cardiomyopathies matched to the same age and time period (148 patients. Results Three operative deaths (7.5% occurred as a result of left ventricular failure in one and multiorgan failure in two patients. There were 14 late deaths, 2 to 67 months after MV procedure. Progress of heart failure was the main cause of death. 18 patients who were still alive took part on the follow-up examination. At a mean follow-up of 50 ± 34 (2–112 months the NYHA class improved significantly from 3.2 ± 0.5 to 2.2 ± 0.4 (p 0.05.

  12. Diaphragmatic left ventricular aneurysm. Clinical features, surgical treatment, and long-term follow-up in 22 patients. (United States)

    Codini, M A; Ruggie, N T; Goldin, M D; Messer, J V; Najafi, H


    Although the formation of a left ventricular aneurysm (LVA) is a common and well-recognized complication of myocardial infarction (MI), diaphragmatic LVA is a rare clinical entity. Of 354 consecutive patients who underwent LVA resection, we describe the clinical features and surgical results of 22 patients (6%) with diaphragmatic LVA. All patients had a history of MI. The principal clinical indication for surgery was heart failure in nine patients, angina pectoris in ten patients, and recurrent ventricular tachycardia unresponsive to medical therapy in three patients. A ventricular septal defect was present in two patients, and moderate to severe mitral regurgitation was present in four patients. Three of the four surgical deaths (operative mortality, 18%) occurred in patients with mitral regurgitation or with ventricular septal defect. Eleven patients are alive at a mean follow-up of 40 months. Six of them are asymptomatic and two have angina at a higher level of physical activity than before surgery. Notable differences exist in the clinical presentation and surgical findings between patients with diaphragmatic and anterior LVA.

  13. Left ventricular assist device implantation in patients after left ventricular reconstruction. (United States)

    Palmen, Meindert; Braun, Jerry; Beeres, Saskia L M A; Klautz, Robert J M


    Left ventricular assist device (LVAD) implantation can be challenging in patients with a prior surgical ventricular restoration (SVR). In this case series of heart failure patients with a history of SVR, we describe the surgical technique and outcome of a customized approach for inflow cannula orientation. Seven patients with a history of SVR with end-stage chronic heart failure were accepted for long-term LVAD support. In all patients, the Dacron patch was removed through left ventriculotomy and a Hegar 22 dilator was inserted at the estimated optimal position of the LVAD inflow cannula. The left ventricle was reconstructed around the dilator from the left ventricular (LV) apex to the base. Finally, the LVAD sewing ring was sutured onto the remaining apical defect and a HeartWare® LVAD was implanted. LVAD implantation was successful in all 7 patients. Transoesophageal echocardiography ensured an adequate LVAD position and inflow and outflow cannula Doppler flow recordings. The mean intensive care unit stay was 5.8 ± 2.6 days, and the hospital stay after surgery was 32 ± 16 days. All patients follow regular visits (follow-up 20 ± 16 months) at the outpatient clinic without any remarkable event. Using the technique described, LVAD implantation in patients after SVR is feasible and safe. © The Author 2016.

  14. Slow Progress in Dune (Left Front Wheel) (United States)


    The left front wheel of NASA's Mars Exploration Rover Opportunity makes slow but steady progress through soft dune material in this movie clip of frames taken by the rover's front hazard identification camera over a period of several days. The sequence starts on Opportunity's 460th martian day, or sol (May 10, 2005) and ends 11 days later. In eight drives during that period, Opportunity advanced a total of 26 centimeters (10 inches) while spinning its wheels enough to have driven 46 meters (151 feet) if there were no slippage. The motion appears to speed up near the end of the clip, but that is an artifact of individual frames being taken less frequently.

  16. Psychotic Symptoms Associated with Left Caudate Infarction

    Directory of Open Access Journals (Sweden)

    Ying-Chih Cheng


    Full Text Available Psychotic symptoms following acquired brain lesion are relatively rare, and thus, the specific association linking such symptoms to the distinct brain structure remains unclear. The frontal–subcortical circuits are thought to modulate motor activity and human behavior, and have been reported to be associated with many neuropsychiatric symptoms. We herein report the case of a 77-year-old man without previous psychiatric disorder who developed a new onset of psychotic symptoms following left caudate infarction. The presented case supports the fact that psychosis might arise from alteration of the distinct brain structure. The functional impairment of the frontal–subcortical circuits may be a critical factor linking the pathogenesis of psychosis associated with acquired brain lesion.

  17. ODEs: is there anything left to do

    Energy Technology Data Exchange (ETDEWEB)

    Gear, C.W.


    Two decades ago many people thought that there was very little left to occupy the researcher in the numerical initial-value problem for ordinary differential equations, but there has since been an enormous increase in the effort devoted to this problem and related software. The question is whether everything is finally done so that more difficult areas can be studied. The development of numerical solution techniques is examined from the identification of a problem to the never-final preparation of automatic codes for the solution of classes of similar problems. A number of ODE problems that are only a part of the way along this path of development are discussed. These problems include ones with highly oscillatory solutions, ones with frequent discontinuities, and ones in which very little accuracy is needed (and which should be integrated at low cost). 4 figures.

  18. What's Left of the Left-Right Dimension? Why the Economic Policy Positions of Europeans Do Not Fit the Left-Right Dimension. (United States)

    Otjes, Simon


    In political science the economic left-right dimension plays a central role. A growing body of evidence shows that the economic policy preferences of a large segment of citizens do not scale sufficiently. Using Mokken scale analysis, this study determines the causes of this phenomenon. Differences in the extent to which the economic policy preferences of citizens fit the left-right dimension can be explained in terms of the interaction between individual level and political system-level variables: citizens who spend more attention to politicians with views that conform to the left-right dimension, have views that conform to the left-right dimension. There is also a role for the legacy of communist dictatorship: citizens who were socialised in democratic countries have views that fit the left-right dimension better than those socialised during communism.

  19. Hurt but still alive: Residual activity in the parahippocampal cortex conditions the recognition of familiar places in a patient with topographic agnosia

    Directory of Open Access Journals (Sweden)

    Mitsouko van Assche


    Photographs of personally familiar and unfamiliar places were displayed during functional magnetic resonance imaging (fMRI. Familiar places were either recognized or unrecognized by the patient and 6 age- and education-matched controls in a visual post-scan recognition test. In fMRI, recognized places were associated with a network comprising the fusiform gyrus in the intact side, but also the right anterior PHC, which included the lesion site. Moreover, this right PHC showed increased connectivity with the left homologous PHC in the intact hemisphere. By contrasting recognized with unrecognized familiar places, we replicate the finding of the joint involvement of the retrosplenial cortex, occipito-temporal areas, and posterior parietal cortex in place recognition. This study shows that the ability for left and right anterior PHC to communicate despite the neurological damage conditioned place recognition success in this patient. It further highlights a hemispheric asymmetry in this process, by showing the fundamental role of the right PHC in topographic agnosia.

  6. Maintaining professionalism in today's business environment: ethical challenges for the pain medicine specialist. (United States)

    Lebovits, Allen


    There are many external influences in today's market force that impair the relationship between the pain medicine specialist and the patient, and ultimately prevent optimal quality of care. This article explores the ethical challenges facing the pain medicine specialist in today's increasingly "business" environment and will offer solutions for maintaining the professionalism of pain medicine. Four commonly encountered bioethical principles in the practice of pain medicine are reviewed: beneficence, nonmaleficence, justice, and autonomy. The following ethical challenges of the pain medicine specialist are reviewed: practicing outside ones specialty area, practice characteristics, the consultant role, the economic lure of aggressive intervention, not evaluating for and treating comorbid psychopathology, reimbursement pressures, workers' compensation, and use of unproven methods. Solutions offered include collegial associations, social responsibility, legislative initiatives, pain education, interdisciplinary evaluation and treatment, improved relationships with third-party payers, reduced racial disparities, and ethics education. Ethics is the "roadmap" that enables the pain medicine specialist to navigate the increasingly murky waters of practicing pain management today by maintaining the professionalism necessary to combat today's "business" pressures.

  20. UFO in the Left Atrium: How to Capture Metal Debris Floating in the Left Atrium. (United States)

    Fassini, Gaetano; Moltrasio, Massimo; Conti, Sergio; Biagioli, Viviana; Tondo, Claudio


    Electrophysiology procedures involving left atrium navigation are becoming more frequent, mostly due to the increase of atrial fibrillation ablation. Mapping catheters of different shapes and size as well as dedicated sheaths are mandatory tools for the accomplishment of procedural end point. Therefore, technical issues are expected, usually unrelated to significant risk. However, any accidental intra-atrial device loss of integrity implies a risk of cerebrovascular embolization. The lack of clear evidence on how to manage these events and the need for a quick solution complicate the scenario. We report an empirical solution in the case of debris floating in the left atrium.

  1. Left Ventricular Hypertrophy Evaluation in Obese Hypertensive Patients: Effect of Left Ventricular Mass Index Criteria

    Directory of Open Access Journals (Sweden)

    Eduardo Cantoni Rosa


    Full Text Available PURPOSE: To evaluate left ventricular mass (LVM index in hypertensive and normotensive obese individuals. METHODS: Using M mode echocardiography, 544 essential hypertensive and 106 normotensive patients were evaluated, and LVM was indexed for body surface area (LVM/BSA and for height² (LVM/h². The 2 indexes were then compared in both populations, in subgroups stratified according to body mass index (BMI: or = 30kg/m². RESULTS: The BSA index does not allow identification of significant differences between BMI subgroups. Indexing by height² provides significantly increased values for high BMI subgroups in normotensive and hypertensive populations. CONCLUSION: Left ventricular hypertrophy (LVH has been underestimated in the obese with the use of LVM/BSA because this index considers obesity as a physiological variable. Indexing by height² allows differences between BMI subgroups to become apparent and seems to be more appropriate for detecting LVH in obese populations.

    Full Text Available Background: early diagnosis of left ventricular mass (LVM inappropriateness and left ventricular hypertrophy (LVH can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. This study was performed to determine if diastolic dysfunction is associated with LVH and inappropriate LVM. Materials and Methods: one hundred and twenty five uncomplicated hypertension from Isfahan Healthy Heart Program underwent two-dimensional echocardiography. Inappropriate LVM was defined as an LVM index greater than 88 g/m2 of body-surface area in women and greater than 102 g/m2 in men. LVH-defined septal and posterior wall thickness greater than 0/9 cm in women and greater than 1 cm in men, respectively. Echocardiographic parameters, including early diastolic peak velocity (E/late diastolic peak velocity (A, deceleration time (DT, and E/early mitral annulus velocity (E′ were measured. Results: the mean systolic and diastolic blood pressure at the patients′ admission day were 142.87 ± 18.12 and 88.45 ± 9.18 mmHg, respectively. Totally, 21.7% of subjects had inappropriate LV mass that moderate and severe abnormal LV mass was revealed in 5.6% and 5.6%, respectively. The mean of age and BMI was significantly higher in patients with moderate left ventricular hypertrophy (P 0.05. Spearman′s Rank test was used to test the correlation between diastolic dysfunction and LV mass (P = 0.025. Conclusion: LVH is correlated with the severity of diastolic dysfunction manifested by the E/A value and deceleration time, but inappropriate LVM can slightly predict diastolic dysfunction severity in uncomplicated hypertension.

  3. Evaluating Today's Landscape Multifunctionality and Providing an Alternative Future: A Normative Scenario Approach

    Directory of Open Access Journals (Sweden)

    Rainer Waldhardt


    Full Text Available Intensive agriculture has had multiple negative effects on the environment across large areas of Europe, including a decrease in the degree to which these landscapes serve multiple functions. A quantitative evaluation of the deficits in landscape multifunctionality is difficult, however, for a given landscape as long as "multifunctional reference landscapes" are lacking. We present an interdisciplinary normative scenario approach to overcome this obstacle. Given the example of the lower Wetter-catchment in the Wetterau region (Hesse, Germany, we compare the existing landscape with an expert-generated multifunctional landscape scenario that may also serve as an alternative future. This approach may inspire policy makers and land users by providing a methodology for the design of alternative multifunctional futures in five steps: (1 documentation of today's landscape structure and land use at the scale of uniformly managed land units; (2 detection of functional deficits of today's landscape considering environmental (soil contamination, groundwater production, water quality, biodiversity, economic (land rent, and societal (landscape perception by its population attributes; (3 compilation of a catalogue of alternative land uses (including linear landscape elements suitable to minimize the detected functional deficits; (4 rule-based modification of today's land-use pattern into a normative scenario; and (5 comparison of today's landscape and the normative scenario by applying the model network ITE²M. Results highlight a strongly unbalanced allocation of private and public goods in today's landscape with severe deficits in environmental and societal landscape features, but a significantly higher land rent. The designed multifunctional scenario, instead, may be preferred by the local population, and their willingness to pay for multifunctionality could potentially compensate calculated opportunity costs. Hence, the generated landscape scenario may be

  4. Endocarditis in left ventricular assist device (United States)

    Thyagarajan, Braghadheeswar; Kumar, Monisha Priyadarshini; Sikachi, Rutuja R; Agrawal, Abhinav


    Summary Heart failure is one of the leading causes of death in developed nations. End stage heart failure often requires cardiac transplantation for survival. The left ventricular assist device (LVAD) has been one of the biggest evolvements in heart failure management often serving as bridge to transplant or destination therapy in advanced heart failure. Like any other medical device, LVAD is associated with complications with infections being reported in many patients. Endocarditis developing secondary to the placement of LVAD is not a frequent, serious and difficult to treat condition with high morbidity and mortality. Currently, there are few retrospective studies and case reports reporting the same. In our review, we found the most common cause of endocarditis in LVAD was due to bacteria. Both bacterial and fungal endocarditis were associated with high morbidity and mortality. In this review we will be discussing the risk factors, organisms involved, diagnostic tests, management strategies, complications, and outcomes in patients who developed endocarditis secondary to LVAD placement.

    Full Text Available In this paper we review studies that investigated tool use disorders in left-brain damaged (LBD patients over the last thirty years. Four tasks are classically used in the field of apraxia: Pantomime of tool use, single tool use, real tool use and mechanical problem solving. Our aim was to address two issues, namely, (1 the role of mechanical knowledge in real tool use and (2 the cognitive mechanisms underlying pantomime of tool use, a task widely employed by clinicians and researchers. To do so, we extracted data from 36 papers and computed the difference between healthy subjects and LBD patients. On the whole, pantomime of tool use is the most difficult task and real tool use is the easiest one. Moreover, associations seem to appear between pantomime of tool use, real tool use and mechanical problem solving. These results suggest that the loss of mechanical knowledge is critical in LBD patients, even if all of those tasks (and particularly pantomime of tool use might put differential demands on semantic memory and working memory.

  6. Challenges training left-handed surgeons. (United States)

    Anderson, Maia; Carballo, Erica; Hughes, David; Behrer, Christopher; Reddy, Rishindra M


    Being left-handed (LH) is considered a disadvantage in surgical training. We sought to understand the perspectives of LH trainees and surgical educators on the challenges and modifications in training LH surgeons. A survey was distributed to surgeons, surgical residents, and medical students about challenges teaching and learning surgical technique. 25 LH surgeons, 65 right-handed (RH) surgeons, and 39 LH trainees completed the survey. Compared to LH surgeons, RH surgeons reported more difficulty (46% vs 16%, p = 0.003) and less comfort teaching LH trainees (28% vs 4%, p = 0.002), and 10 (15%) reported that LH trainees have less technical ability. RH surgeons identified challenges translating technique to LH trainees and physical limitations of an environment optimized for right-handed mechanics. The disadvantage LH surgical trainees face is due to barriers in training rather than inherent lesser ability. Nonetheless, minimal modifications are made to overcome these barriers.

    Miller, Erin M; Hinton, Robert B; Czosek, Richard; Lorts, Angela; Parrott, Ashley; Shikany, Amy R; Ittenbach, Richard F; Ware, Stephanie M


    Left ventricular noncompaction (LVNC) can occur in isolation or can co-occur with a cardiomyopathy phenotype or cardiovascular malformation. The yield of cardiomyopathy gene panel testing in infants, children, and adolescents with a diagnosis of LVNC is unknown. By characterizing a pediatric population with LVNC, we sought to determine the yield of cardiomyopathy gene panel testing, distinguish the yield of testing for LVNC with or without co-occurring cardiac findings, and define additional factors influencing genetic testing yield. One hundred twenty-eight individuals diagnosed with LVNC at ≤21 years of age were identified, including 59% with idiopathic pathogenesis, 32% with familial disease, and 9% with a syndromic or metabolic diagnosis. Overall, 75 individuals had either cardiomyopathy gene panel (n=65) or known variant testing (n=10). The yield of cardiomyopathy gene panel testing was 9%. The severity of LVNC by imaging criteria was not associated with positive genetic testing, co-occurring cardiac features, pathogenesis, family history, or myocardial dysfunction. Individuals with isolated LVNC were significantly less likely to have a positive genetic testing result compared with those with LVNC and co-occurring cardiomyopathy (0% versus 12%, respectively; P testing should be considered in individuals with cardiomyopathy co-occurring with LVNC. These data do not suggest an indication for cardiomyopathy gene panel testing in individuals with isolated LVNC in the absence of a family history of cardiomyopathy. © 2017 American Heart Association, Inc.

  8. Left ventricular noncompaction: Clinical-echocardiographic study

    Directory of Open Access Journals (Sweden)

    Nikolić Aleksandra


    Full Text Available Background/Aim. Left ventricular noncompaction (LVNC is a disorder in endomyocardial morphogenesis, seen either isolated (in the absence of other cardiac anomalies or in association with congenital heart disease and some neuromuscular diseases. Intrauterine arrest of the compaction of myocardial fibers is postulated to be the reason of LVNC. Recognition of this condition is extremely important due to its high mortality and morbidity that lead to progressive heart failure, ventricular arrhythmias and thromboembolic events. The aim of this study was to determine the prevalence and clinical presentation of LVNC among consecutive outpatients according to clinical and echocardiographyic findings. Methode. A total of 3,854 consecutive patients examined at the Institute for Cardiovascular Diseases within a period January 2006 - January 2007 were included in the study. All the patients underwent echocardiographic examination using the same equipment (Vivid 7, GE Medical System. Echocardiographic parameters and clinical presentation in patients with echocardiographic criteria for LVNC were analyzed. Results. Analyzing 3,854 consecutive outpatients, using two-dimensional Color Doppler echocardiography from January 2006 to January 2007, 12 patients met the criteria for LVNC. Seven of them were male. The mean age at diagnosis was 45 ± 15 years. Analyzing clinical manifestation of LVNC it was found that seven patients had signs of heart failure, six had arrhythmias with no embolic events. Conclusion. Our results suggest that the real prevalence of LVNC may be higher than expected. New studies have to be done to solve this problem.

  9. Cilia in Left-Right Symmetry Breaking. (United States)

    Shinohara, Kyosuke; Hamada, Hiroshi


    Visceral organs of vertebrates show left-right (L-R) asymmetry with regard to their position and morphology. Cilia play essential role in generating L-R asymmetry. A number of genes required for L-R asymmetry have now been identified in vertebrates, including human, many of which contribute to the formation and motility of cilia. In the mouse embryo, breaking of L-R symmetry occurs in the ventral node, where two types of cilia (motile and immotile) are present. Motile cilia are located at the central region of the node, and generate a leftward fluid flow. These motile cilia at the node are unique in that they rotate in the clockwise direction, unlike other immotile cilia such as airway cilia that show planar beating. The second type of cilia essential for L-R asymmetry is immotile cilia that are peripherally located immotile cilia. They sense a flow-dependent signal, which is either chemical or mechanical in nature. Although Ca 2+ signaling is implicated in flow sensing, the precise mechanism remains unknown.

  10. Evaluation of left cardiac function by exercise in hypertrophic cardiomyopathy

    International Nuclear Information System (INIS)

    Konishi, Tokuji; Horayama, Norihisa; Hamada, Masayuki; Nakano, Takeshi; Takezawa, Hideo


    Left ventricular systolic and diastolic features at rest and exercise in hypertrophic cardiomyopathy were evaluated by Fourier analysis of blood pool scintigraphy (intracorporeal labelling with sup(99m)Tc-RBC). In the normal group (17 subjects), the left ventricular ejection fraction showed a linear increase, but no abnormality of regional ventricular wall motion, by multistage exercises. The hypertrophic cardiomyopathy group showed higher left ventricular ejection fractions at rest than those of the normal group, and in the HCM group (non-obstructive, from morphological features; 7 cases) the left ventricular ejection fraction did not increase any more when it reached a certain plateau in accordance with increased stress. In the HOCM (obstructive; 5 cases), the left ventricular ejection fraction showed a decreasing tendency as the stress was increased and also showed contractile abnormalities from the left ventricular center to the apex. Fourier analysis was effective for the evaluation of these changes. (Chiba, N.)

  11. Isolated Left Pulmonary Artery Agenesis: A Case Report

    Directory of Open Access Journals (Sweden)

    Tansel Ansal Balcı


    Full Text Available Unilateral pulmonary artery agenesis without any cardiovascular malformation is a rare anomaly. We present the imaging findings of a patient who was diagnosed as isolated left pulmonary artery agenesis. A 27-year-old female patient was admitted to our hospital due to dyspnea during exercise for five years. Chest X-ray revealed minimally small left pulmonary hilum and left lung. She was admitted to our clinic with the suspicion of pulmonary artery pathology. Absent perfusion of the left lung with normal ventilation was visualized on scintigraphy. MDCT angiography of pulmonary arteries showed absent left main pulmonary artery with systemic collaterals around left hemithorax. Pulmonary artery agenesis can be asymptomatic and isolated until adulthood. Both scintigraphy and CT angiography images of pulmonary artery agenesis of a patient are rare in the literature. Pulmonary ventilation- perfusion scintigraphy can be used not only for pulmonary embolism but also pathologies involving pulmonary artery and its branches. (MIRT 2012;21:80-83

  12. The compression syndrome of the left renal vein

    International Nuclear Information System (INIS)

    Justich, E.


    Severe compression of the left renal vein produces a pressure gradient between it and the inferior vena cava and results in changes in haemodynamics. The cause of the narrowing is usually the aorta, less commonly the superior mesenteric artery. Compression of the left renal vein may be responsible for a number of abnormalities such as primary varicoceles, primary varices of the ovarian, renal, pelvic and ureteric veins on the left, the more frequent occurrence of unilateral renal vein thrombosis on the left and the development of renovascular hypertension. One hundred and twenty-three selective phlebograms of the left renal vein and CT examinations of this structure in a further 87 patients acting as a control group were carried out. The significance of compression of the left renal vein as an aetiological factor in the development of the above mentioned abnormalities is discussed. (orig.) [de

    For ease of use and to aid precision, left-handed instruments are invaluable to the left-handed surgeon. Although they exist, they are not available in many surgical centres. As a result, most operating theatre staff (including many left-handers) have little knowledge of their value or even application. With specific reference to cardiac surgery, this article addresses the ways in which they differ, why they are needed and what is required - with tips on use.

    Cardiac rupture after blunt trauma is rare and associated with high mortality. The anatomic pattern of blunt cardiac rupture has been demonstrated with the right cardiac chambers more frequently affected than the left. Furthermore, left atrial injury is usually restricted to the atrial appendage and the pulmonary vein-atrial junction. Herein, we report the first case of a 61-year old man with a rupture of the left atrial roof after blunt trauma with minimal thoracic injury.

    Full Text Available Dual left anterior descending coronary artery is a rare congenital anomaly with 4 subtypes. Double left anterior descending coronary artery originating from the left main stem and the right coronary artery (type IV dual left anterior descending artery has been reported to occur in 0.01% to 0.7% of patients undergoing cardiac catheterization. We report a case of a 49-year-old woman who was found to have this anomaly during coronary angiography. The patient had been complaining of chest pain that mimics angina pectoris and exercise tolerance test was positive for myocardial ischemia.

  18. Detection of left ventricular thrombi by computerised tomography

    International Nuclear Information System (INIS)

    Nair, C.K.; Sketch, M.H.; Mahoney, P.D.; Lynch, J.D.; Mooss, A.N.; Kenney, N.P.


    Sixteen patients suspected of having left ventricular mural thrombi were studied. All had suffered transmural myocardial infarction. Fifteen patients had a ventricular aneurysm. One had had systemic emboli. The mean length of time between the myocardial infarction and the study was 14.8 months, with a range of one month to 79 months. All patients underwent computerised tomography of the heart, M-mode echocardiography (M-mode), and two-dimensional echocardiography (2-D). Eight patients underwent left ventricular cineangiography. Five patients had surgical confirmation. Computerised tomography, two-dimensional, and M-mode echocardiography predicted left ventricular mural thrombi in 10, eight, and one of the 16 patients, respectively. Left ventricular cineangiography predicted left ventricular mural thrombi in four out of eight patients. Computerised tomography and left ventricular cineangiography correctly predicted the presence or absence of left ventricular thrombi in all five patients who underwent operation. In the same group, however, two-dimensional and M-mode echocardiography failed to predict the presence of thrombi in one and three patients, respectively. Among the 11 patients without surgical confirmation, one, in whom no left ventricular thrombi were shown by M-mode and two-dimensional echocardiography, was found to have thrombi on computerised tomography. In another, two-dimensional echocardiography was positive but this finding was not confirmed either by computerised tomography or by left ventricular angiography. (author)

  19. Unruptured aneurysm of the left sinus of Valsalva compressing the left main coronary artery: successful percutaneous treatment. (United States)

    Hausinger, P; Sasi, V; Volford, G; Bitay, M; Bogáts, G; Thury, A; Palkó, A; Forster, T; Nemes, A


    Aneurysm of the left sinus of Valsalva is an extremely rare entity. It may be asymptomatic and incidentally discovered, or may be symptomatic and manifest acutely with compression of adjacent cardiac structures. Encasement of the left main coronary artery by such an aneurysm is a recognized but infrequent complication that can lead to severe coronary insufficiency. Surgical decompression of the left main coronary artery is the standard treatment for such conditions. We describe a patient presenting with extrinsic compression of the left main coronary artery by a large unruptured aneurysm of the left sinus of Valsalva occurring 4 months after unsuccessful surgical repair. Since reoperation was considered high-risk for the patient, successful fractional flow reserve- and intravascular ultrasound-guided percutaneous treatment of the left main coronary artery was performed with implantation of one bare-metal stent.

  2. Left atrial strain: a new parameter for assessment of left ventricular filling pressure. (United States)

    Cameli, Matteo; Mandoli, Giulia Elena; Loiacono, Ferdinando; Dini, Frank Lloyd; Henein, Michael; Mondillo, Sergio


    In order to obtain accurate diagnosis, treatment and prognostication in many cardiac conditions, there is a need for assessment of left ventricular (LV) filling pressure. While systole depends on ejection function of LV, diastole and its disturbances influence filling function and pressures. The commonest condition that represents the latter is heart failure with preserved ejection fraction in which LV ejection is maintained, but diastole is disturbed and hence filling pressures are raised. Significant diastolic dysfunction results in raised LV end-diastolic pressure, mean left atrial (LA) pressure and pulmonary capillary wedge pressure, all referred to as LV filling pressures. Left and right heart catheterization has traditionally been used as the gold standard investigation for assessing these pressures. More recently, Doppler echocardiography has taken over such application because of its noninvasive nature and for being patient friendly. A number of indices are used to achieve accurate assessment of filling pressures including: LV pulsed-wave filling velocities (E/A ratio, E wave deceleration time), pulmonary venous flow (S wave and D wave), tissue Doppler imaging (E' wave and E/E' ratio) and LA volume index. LA longitudinal strain derived from speckle tracking echocardiography (STE) is also sensitive in estimating intracavitary pressures. It is angle-independent, thus overcomes Doppler limitations and provides highly reproducible measures of LA deformation. This review examines the application of various Doppler echocardiographic techniques in assessing LV filling pressures, in particular the emerging role of STE in assessing LA pressures in various conditions, e.g., HF, arterial hypertension and atrial fibrillation.

  3. Limited left atrial surgical ablation effectively treats atrial fibrillation but decreases left atrial function. (United States)

    Compier, Marieke G; Tops, Laurens F; Braun, Jerry; Zeppenfeld, Katja; Klautz, Robert J; Schalij, Martin J; Trines, Serge A


    Limited left atrial (LA) surgical ablation with bipolar radiofrequency is considered to be an effective procedure for treatment of atrial fibrillation (AF). We studied whether limited LA surgical ablation concomitant to cardiac surgery is able to maintain LA function. Thirty-six consecutive patients (age 66 ± 12 years, 53% male, 78% persistent AF) scheduled for valve surgery and/or coronary revascularization and concomitant LA surgical ablation were included. Epicardial pulmonary vein isolation (PVI) and additional endo-epicardial lines were performed using bipolar radiofrequency. An age- and gender-matched control group (n = 36, age 66 ± 9 years, 69% male, 81% paroxysmal AF) was selected from patients undergoing concomitant epicardial PVI only. Left atrial dimensions and function were assessed on two-dimensional echocardiography preoperatively and at 3- and 12-month follow-up. Sinus rhythm (SR) maintenance was 67% for limited LA ablation and 81% for PVI at 1-year follow-up (P = 0.18). Left atrial volume decreased from 72 ± 21 to 50 ± 14 mL (31%, P Atrial transport function was restored in 54% of patients in SR after limited LA ablation compared with 100% of patients in SR after PVI. Atrial strain and contraction parameters (LA ejection fraction, A-wave velocity, reservoir function, and strain rate) significantly decreased after limited LA ablation. After PVI, strain and contraction parameters remained unchanged. Even limited LA ablation decreased LA volume, contraction, transport function, and compliance, indicating both reverse remodelling combined with significant functional deterioration. In contrast, surgical PVI decreased LA volume while function remained unchanged. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2016.

    Full Text Available There is more than one way to manage hair loss surgically. Apart from hair transplantation, there are other techniques which have been used by many to treat baldness. This article attempts to review the surgical methodology and philosophy that have acted as guiding lights in the approach to surgical treatment of baldness over the years and reviews the current role of other techniques in the armamentarium of hair restoration surgeons today.

  11. Memorization of Sequences of Movements of the Right or the Left Hand by Right- and Left-Handers: Vector Coding. (United States)

    Bobrova, E V; Bogacheva, I N; Lyakhovetskii, V A; Fabinskaja, A A; Fomina, E V


    In order to test the hypothesis of hemisphere specialization for different types of information coding (the right hemisphere, for positional coding; the left one, for vector coding), we analyzed the errors of right and left-handers during a task involving the memorization of sequences of movements by the left or the right hand, which activates vector coding by changing the order of movements in memorized sequences. The task was first performed by the right or the left hand, then by the opposite hand. It was found that both'right- and left-handers use the information about the previous movements of the dominant hand, but not of the non-dom" inant one. After changing the hand, right-handers use the information about previous movements of the second hand, while left-handers do not. We compared our results with the data of previous experiments, in which positional coding was activated, and concluded that both right- and left-handers use vector coding for memorizing the sequences of their dominant hands and positional coding for memorizing the sequences of non-dominant hand. No similar patterns of errors were found between right- and left-handers after changing the hand, which suggests that in right- and left-handersthe skills are transferred in different ways depending on the type of coding.

  12. The thermal effect on the left-handedness of the mesoscopic composite right-Left handed transmission line (United States)

    Wei, Xiao-Jing; Zhao, Shun-Cai; Guo, Hong-Wei


    Starting from the quantum fluctuation of current in the mesoscopic composite right-left handed transmission line (CRLH-TL) in the thermal Fock state, we investigate the left-handedness dependent of the frequencies, intensity and quantum fluctuations of the current field in the CRLH-TL under different thermal environment. The results show that the intensity and quantum fluctuations of current field in lower frequency bands affect the left-handedness distinctly under different thermal environment. The thermal effect on the left-handedness in the mesoscopic CRLH-TL deserves further experimental investigation in its miniaturization application.

  13. Nipro extra-corporeal left ventricular assist device fitting after left ventricular reconstruction with mitral valve plasty. (United States)

    Arakawa, Mamoru; Yamaguchi, Atsushi; Nishimura, Takashi; Itoh, Satoshi; Yuri, Koichi; Kyo, Shunei; Adachi, Hideo


    Both left ventricular assist device and left ventricular reconstruction are treatment choices for severe heart failure conditions. Our institution performed a left ventricular assist device installation following a left ventricular reconstruction procedure on a 42-year-old male patient who presented with dilated cardiomyopathy and low cardiac output syndrome. A mitral valve plasty was used to correct the acute mitral valve regurgitation and we performed a Nipro extra-corporeal left ventricular assist device installation on post-operative day 14. Due to the left ventricular reconstruction that the patient had in a previous operation, we needed to attach an apical cuff on posterior apex, insert the inflow cannula with a large curve, and shift the skin insertion site laterally to the left. We assessed the angle between the cardiac longitudinal axis and the inflow cannula using computed tomography. The patient did not complain of any subjective symptoms of heart failure. Although Nipro extra-corporeal left ventricular assist device installation after left ventricular reconstruction has several difficulties historically, we have experienced a successful case.

  14. Career development tips for today's nursing academic: bibliometrics, altmetrics and social media. (United States)

    Smith, Derek R; Watson, Roger


    A discussion of bibliometrics, altmetrics and social media for the contemporary nursing scholar and academic researcher. Today's nursing academic faces myriad challenges in balancing their daily life and, in recent years, academic survival has been increasingly challenged by the various research assessment exercises that evaluate the performance of knowledge institutions. As such, it is essential that today's nursing academic keep up to date with the core competencies needed for survival in a modern research career, particularly the intersecting triad of bibliometrics, altmetrics and social media. Discussion paper. Published literature and relevant websites. The rise of social media and altmetrics has important implications for contemporary nursing scholars who publish their research. Some fundamental questions when choosing a journal might be 'does it have a Twitter and/or Facebook site, or a blog (or all three)'; and 'does it have any other presence on social media, such as LinkedIn, Wikipedia, YouTube, ResearchGate and so on?' Another consequence of embracing social media is that individual academics should also develop their own strategies for promoting and disseminating their work as widely as possible. The rising importance of social media and altmetrics can no longer be ignored, and today's nursing academic now has another facet to consider in their scholarly activities. Despite the changing nature of research dissemination, however, it is still important to recognize the undoubted value of established knowledge dissemination routes (that being the peer-reviewed publication). © 2016 John Wiley & Sons Ltd.

  15. Left ventricular function in hypertrophic cardiomyopathy

    International Nuclear Information System (INIS)

    Takahashi, Hiromi; Yamaguchi, Ryutaro; Ifuku, Masayasu


    The present study was to investigate of left ventricular (LV) function during exercise in 26 patients with hypertrophic cardiomyopathy(HCM) usingTc-99m equilibrium angiocardiography, and to elucidate the mechanism of impaired functional reserve during exercise. In patients with HCM, LV ejection fraction decreased from 65 ± 8 (mean ± SD) % at rest to 59 ± 18 % at peak exercise, in contrast to an increase among controls (from 56 ± 9 % to 64 ± 9 %). As compared with resting values, cardiac output increased to 168 ± 24 % at peak exercise in HCM, but the increase was significantly less than that in controls (215 ± 47 %). Stroke volume decreased gradually to 83 ± 16 % during exercise in HCM, while it increased to 114 ± 10 % at an exercise level of half intensity, and it decreased slightly to 106 ± 16 % at peak exercise. LV end-systolic volume decreased among controls to 78 ± 27 % at peak exercise, but remained unchanged in HCM (118 ± 58 %). An increase in peak ejection rate at peak exercise was less in HCM than in controls (143 ± 26 % vs 170 ± 42 %). No significant differences were observed between the two groups concerning changes in indices of LV diastolic function including LV end-diastolic volume, peak filling rate or 1/3 filling rate during exercise. In the analysis of LV function curves, pulmonary arterial diastolic pressure increased to a greater extent in HCM than in controls (19 ± 6 mmHg vs 11 ± 6 mmHg); whereas, an increase in the stroke work index was less in HCM (80 ± 26 g.m/m 2 /beat vs 121 ± 21 g.m/m 2 /beat) at peak exercise. Thus, the LV function curve shifted downward and to the right in patients with HCM. The above findings indicate that LV functional reserve during exercise is impaired, especially as to systolic function in patients with HCM, while deterioration of diastolic function may be partly compromised by elevated filling pressure.

  16. Left ventricular biomechanics in professional football players. (United States)

    von Lueder, T G; Hodt, A; Gjerdalen, G F; Steine, K


    Chronic exercise induces adaptive changes of left ventricular (LV) ejection and filling capacities which may be detected by novel speckle-tracking echocardiography (STE) and tissue Doppler imaging (TDI)-based techniques. A total of 103 consecutive male elite Norwegian soccer players and 46 age-matched healthy controls underwent echocardiography at rest. STE was used to assess LV torsional mechanics and LV systolic longitudinal strain (LS). Diastolic function was evaluated by trans-mitral blood flow, mitral annular velocities by TDI, and LV inflow propagation velocity by color M-mode. Despite similar global LS, players displayed lower basal wall and higher apical wall LS values vs controls, resulting in an incremental base-to-apex gradient of LS. Color M-mode and TDI-derived data were similar in both groups. Peak systolic twist rate (TWR) was significantly lower in players (86.4±2.8 vs controls 101.9±5.2 deg/s, P<.01). Diastolic untwisting rate (UTWR) was higher in players (-124.5±4.2 vs -106.9±6.7 deg/s) and peaked earlier during the cardiac cycle (112.7±0.8 vs 117.4±2.4% of systole duration, both P<.05). Untwisting/twisting ratio (-1.48±0.05 vs -1.11±0.08; P<.001) and untwisting performance (=UTR/TW; -9.25±0.34 vs -7.38±0.40 s -1 , P<.01) were increased in players. Augmented diastolic wall strain (DWS), a novel measure of LV compliance in players, was associated with improved myocardial mechanical efficiency. The described myocardial biomechanics may underlie augmented exertional cardiac function in athletes and may have a potential role to characterize athlete's heart by itself or to distinguish it from hypertensive or hypertrophic cardiomyopathy. © 2017 John Wiley & Sons A/S.

    NARCIS (Netherlands)

    Saouti, N.; Hindori, V.; Morshuis, W.J.; Heijmen, R.H.


    OBJECTIVES: Intentional covering of the left subclavian artery (LSA) as part of thoracic endovascular aortic repair (TEVAR) can cause (posterior) strokes or left arm malperfusion. LSA revascularization can be done as prophylaxis against, or as treatment of, these complications. We report our
