    Full Text Available There are times when something is simply so familiar that we can no longer see it at all. It can be a story, or a concept, or even a flesh-and-blood person. Familiarity breeds not only contempt, but a kind of invisibility as well. For too many of us, such is the case with Sir William Osler. In his time (1849–1919, many considered him to be one of the greatest practitioners, teachers, and writers ever in the field of medicine. He was instrumental in the founding of the Medical Library Association (MLA and was elected its second president.

    William Osler (1849-1919) is generally regarded as one of the greatest and most respected physicians in the history of medicine. As an outstanding clinician and a professor of medicine at four universities in three countries he exerted a profound influence on medical education. His textbook "The Principles and Practice of Medicine" became the most popular treatise on medicine in the world. He emphasized the value of hard work. His compassion and concern for patients, students and colleagues reflected his personality. Osler's humanism, his philosophy and views did not lose their validity even today.

    2002-01-01

    Sir William (Bill) Mitchell, former President of the CERN Council, died on 30th October 2002 at the age of 77. Mitchell was professor of Physics at Oxford University from 1978 to 1989, having previously been Professor of Physics, Dean of Science and Deputy Vice-Chancellor at Reading University. From 1985 to 1990 he was Chairman of the UK's Science and Engineering Research Council (SERC), which at the time was the funding agency for the UK's participation in the CERN programme. As Chairman, Mitchell was one of the UK representatives on the CERN Council, and in 1991 he was elected President, a position he held for three years. This was a difficult period for CERN. Financial problems were being faced in many member states, notably in Germany as a result of unification. This led to calls for reductions in the CERN budget and, more significantly, to requests for delays in consderation of future programmes. On the other hand for the future of CERN and the progress of elementary particle physics, it was necessary...

The 50th anniversary celebration of Troy's hospital brought William Osler to the city as the keynote speaker. This speech, delivered on November 28, 1900, is one of Sir William's less well known addresses. Osler began his comments with Sir Thomas More's Utopia and talked at length about the hospital, its obligations, the influences it has upon the community, and the role of physicians and surgeons. He broached one of his old saws, the salary of attending physicians and their needed role in hospital management. His words were published in the diamond jubilee's records, but the hospital did not outlive its prominent guest professor, and it closed its doors in 1914. Just like the great historical city of Troy, New York's own Troy was on the brink of decline, and its hospital would be the first fatality. Therefore, it is almost prescient that the words of Osler, taken into historical context juxtaposed against the socioeconomic forces at work, are akin to the Greek's offering of a wooden edifice to end the Trojan War.

    William Richard Gowers is one of the great pioneers in neurology and the author of the well-known neurology textbook, "A Manual of Diseases of the Nervous System." His concepts of neurology are based on meticulously and carefully accumulated knowledge of history, observations, and neurological examinations of patients with various neurological diseases. He is not only a great neurologist but also a great teacher who loves teaching students and physicians through well-prepared lectures. We can glean the essence of the field of neurology through his life story and numerous writings concerning neurological diseases.

  12. Sir William Petty: modern epidemiologist (1623-1687).

    Science.gov (United States)

    Banta, J E

    1987-01-01

    William Petty, physician, epidemiologist, political economist, demographer, cartographer, and administrator was an intellectual product of the seventeenth century. Petty was born in the year 1623 in Romsey, England of lower middle class parents; however, by the time of his death in 1687 he had become a knight of the realm, founder of the Royal Society, and friend of kings. Petty's life reflected the northern renaissance which induced such dramatic changes in science, technology, politics, and entrepreneurship. His education was eclectic, nonetheless he took his Doctor of Physic degree from Oxford in 1649 and became an Oxford don, where he spent the next few years as an academic before undertaking a definitive survey of Ireland on behalf of the Cromwell government. Ireland changed Petty's destiny and he became a man of the world and entrepreneur which stimulated his interest in public policy formulation and economics. It was Petty's peculiar genius to be innovative in the application of measurement, statistics, and mathematics to socioeconomic and demographic phenomena. As a physician he related his knowledge of health and disease to these phenomena in what in the modern context would be called human ecology or social epidemiology. These relationships and their measurement were employed to establish an objective set of data which could be analyzed for the purpose of rational public policy planning by the state. This scientific approach to public policy places Petty squarely in the context of modern epidemiologic and public health practice and marks the initiation of a major use of the epidemiologic method.

Este vínculo encierra la clave para la comprensión de su excepcional aportación a la historiografía del arte español. Sus diversas actividades, como historiador del arte, coleccionista de libros y cuadros, y director de ediciones privadas de libros raros, fueron todas manifestaciones de su gran fascinación por el paralelo entre la literatura y el arte, la palabra y la imagen. Tal relación se encuentra incluso en el esquema decorativo de su biblioteca.This article examines the remarkable unity between Sir William Stirling Maxwell's art history, his library and his art collection and argües that this relationship is the key to understanding his unique contribution to scholarship of Spanish art. In particular, it will be shown that his actlvities as an art historian, bibliophile, art collector and editor of prívate editions of rare books were all expressions of his fascination with the relationship between literature and art in general, and more specifically between word and image. Even the decorative scheme of his library emphasised this relationship.

    Wessels, Quenton; Correia, Janine Carla; Taylor, Adam M

    2016-11-01

    Sir William Turner, a Lancastrian, was renowned as a scientist, anatomist and a great reformer of medical education. His students became anatomists at various international institutions, which consequently shaped the future of anatomy as a subject matter both in the United Kingdom and in South Africa. Although Turner's accomplishments have been documented, little is known about the details that determined his career path and the individuals that shaped his future. Here the authors aim to highlight some aspects of Turner's academic achievements and his personal life as well as how he crossed paths with other great minds of the Victorian era including Richard Owen, Charles Darwin, James Paget and Joseph Lister. © The Author(s) 2015.

    2004-08-01

    Sir William Burnett (1779-1861) had an active career as a Royal Navy surgeon in the French Revolutionary and Napoleonic Wars, including service at the battles of St Vincent, the Nile and Trafalgar. From 1822 to 1855 he was professional head of the Royal Naval Medical Department, when he provided effective leadership in a time of great change. Although his official work earned him the reputation of a "hard-working, unimaginative, somewhat harsh man", his correspondence shows a very humane centre under the official carapace. His official performance and reputation were both eroded towards the end of his career by his determined promotion of zinc chloride, for which he held lucrative patents.

    When Ian came to Oxford almost a decade ago he brought with him experience of very different institutions but also respect and sensitivity towards this one. It did not take him long to appreciate the fundamental good sense of the English custom of the coffee break at 11 and the tea break at 4. But Ian was a dynamo and we learned that the true purpose of the coffee break is to initiate a physics discussion which, had it not been for the intervention of lunch, would still have been going on at tea time. Ian was a man at ease with himself and forever generous to others. He was an ever-present inhabitant of the Discussion Room in Keble Road and loved to include anyone who was interested in the subject under consideration. Students, post-docs, staff; we have spent many happy hours exploring the magical world of theoretical physics in Ian's company…

  3. Obituary: Ian R. Bartky, 1934-2007

    Dick, Steven J.

    2009-01-01

    Ian Robertson Bartky, a physical chemist who turned to history for his second career, died 18 December 2007 of complications from lung cancer. He was 73. In addition to his scientific career, he will be remembered for his meticulous research on the evolution of time systems, especially for his two books Selling the True Time: Nineteenth Century Timekeeping in America (Stanford University Press, 2000), and One Time Fits All: The Campaigns for Global Uniformity (Stanford University Press, 2007). Ian was born on 15 March 1934 in Chicago, Illinois. He was the son of Walter Bartky, a Professor of Astronomy at the University of Chicago, and eventually its Dean of the Division of Physical Sciences. The elder Bartky's astronomy textbook, Highlights of Astronomy, published in 1935 and reprinted as late as 1964, includes a considerable discussion of time and standard meridians, which may have influenced Ian, even though his father died in 1958 at the age of 57 when Ian would have been only in his early 20s. Imbued with the love of science from his father, Ian graduated from Illinois Institute of Technology, and went on to obtain his doctorate in physical chemistry from the University of California Berkeley. He mentor was Nobelist William F. Giauque, and Ian always spoke fondly of Giauque's influence in setting rigorous standards that Ian followed when he joined the National Bureau of Standards [NBS] in 1961. Ian spent most of his career there, and it was there that he acquired his professional interest in time, notably when the House Commerce Committee asked him in the mid-1970s to determine whether the dates of Daylight Saving Time should be extended. This resulted in an NBS report in 1976, which concluded that any energy savings would be miniscule. With his usual attention to detail, Ian researched the entire history of the problem, and thus acquired his second great love after science--history. With Elizabeth Harrison he published a well-known article on the issues

  7. Ian Macpherson's Writing of the Disaster

    Directory of Open Access Journals (Sweden)

    Timothy C. Baker

    2008-10-01

    Full Text Available The Scottish Renaissance novelist Ian Macpherson is rarely considered within either Scottish or British contexts. This discussion of his novels demonstrates that they simultaneously serve both as reworkings of the pastoral tradition and as documents of what Maurice Blanchot calls the disaster. Offering a close reading of the novels themselves, focusing on Macpherson’s final novel, Wild Harbour, as well as a comparison with the more celebrated work of D.H. Lawrence, this article argues that Macpherson deserves significant reappraisal as both exemplars of the Scottish Renaissance tradition and as philosophically-engaged approaches to modernity.

    2000-06-01

    It has been suggested that SIRS are triggered by superfluous pro-inflammatory cytokine production, and that organ injury is caused by uncontrolled inflammatory responses. However, the results of clinical studies, on the usefulness of specific cytokine antagonists and anti-TNF antibodies for the treatment of septic shock, have been unsatisfactory. The reason for this might have been that when uncontrolled inflammatory reactions progressed locally, anti-inflammatory reactions were elevated in the circulated blood by way of CARS, thus the timing of administration and pharmacokinetics did not match clinical course. Recent research has shown that SIRS is always accompanied by CARS, and since it seems to do the amplitude of SIRS and CARS to each other so that there may be a deep valley, if there is a high mountain. We introduce the recent knowledge which indicates that SIRS is a preliminary alert for not only organ dysfunction but also immunosuppression after severe injury or major surgery.

    In this paper, a fractional wave equation for the average neutron motion in a nuclear reactor is considered. This representation covers the full spectrum of the average neutron transport behavior, i.e., Fick ian and non-Fick ian effects. The fractional diffusion model retains the main dynamic characteristics of the neutron motion. The relaxation time associated with a rapid variation in the neutron flux contains an adjustable parameter, which can be manipulated to obtain the best representation of the neutron transport phenomena.

  6. One day, Sir, you may tax it

    CERN Multimedia

    2011-01-01

    “One day, Sir, you may tax it”… Those are the words I used to get the audience's attention during my talk at the World Economic Forum’s annual meeting in Davos, where I was invited to speak about the science agenda in 2011. For those of you who don’t know the quote, it was Michael Faraday’s response to William Gladstone when asked to comment on the utility of his blue-sky research into the newfangled phenomenon of electricity.   So what does a 19th century English scientist have to do with the science agenda today? A great deal, I would contend. Faraday was doing basic science, but he had the foresight to realise that through applied research his findings could one day be developed into something taxable – as it turned out, electric light. Faraday had a sense of the potential of his blue-sky research, but he also appreciated that basic science alone is not enough. This was my key message in Davos. Governments often speak of ...

  12. A Transdisciplinary Mind: An Interview with Ian Mitroff

    Directory of Open Access Journals (Sweden)

    Russ Volckmann

    2006-06-01

    Full Text Available Known more widely as the “Father of Crisis Management,” University of Southern California professor Ian Mitroff came to the work of Ken Wilber and integral theory over two decades ago. No one else has brought an integral perspective to the fields of management and organization theory for as long as Mitroff. In this interview he talks about the development of his theories, the people he has worked closely with, his spiritual development and the streams of his work, including his research on spirituality in organizations. While his involvement with Wilber’s Integral Institute is not what he would like it to be, he sees there the potential to develop an institution that addresses the politicization and failures of our institutions of higher education. In the face of the crisis in leadership, integral and transdisciplinary approaches have the potential for making a positive difference as we are faced with the dissolution of distinctions that underlie how we make meaning in the world.

The relentless intelligence of some young peopleeducated outside the Romanian land, as Dionisie Pop Marţian (1829-1865, has started the struggle for "the economic emancipation of thenation" by promoting the ideas, the principles and the institutions on whichwas build the prosperity of the West. Seen as a "reactionary" or as a "manof progress", Marţian has delivered a heterogeneous economic outlook, amixture of liberal principles and protectionist principles. The mostsignificant "protection" supported by Marţian was the one againstignorance. The compilation made by Marţian using the works of variousauthors sustaining the "social economy" shows the dimensions of economicbackwardness - the absence of current economic terms from the lexicon.Marţian invents some economic terms, which are understandable, such as:„comerciu”(trade, „manufaptură” (manufacture, „product”, „const”,„fair price”, „banc-rupt” etc. Marţian's mission was clear: "the spreadingof economics through speaking and writing.".

  17. Modification of the IAN-R1 reactor

    International Nuclear Information System (INIS)

    Jaime, J.; Ahumada, S.; Spin, R.A.

    1990-01-01

    The IAN-R1 reactor is the only nuclear reactor operating in Colombia; it is installed at the Institute of Nuclear Affairs (AIN) in Bogota, which is an official body coming under the Ministry of Mining and Energy. This reactor started operation in January 1965 with a rated power of 10 kW and was modified a year later to operate at 20 kW, which has been its rated power up to the present. Given its importance for the application of nuclear technology in Columbia for various purposes, principally in the areas of neutron activation analysis, determination of uranium content in minerals using the delayed neutron counting method, production of certain radioisotopes such as 198 Au and 82 Br for engineering applications, and production of radioactive material for teaching and research purposes, research has been in progress for some years into ways of increasing its power. The study on experimental requirements and on the demand for locally produced radioisotopes came to the conclusion that its power should be increased to 1000 kW, which would allow the facility to remain on the same site. The modification includes conversion of the core to low-enriched fuel, operation up to 1 MW, modification of the shielding, renovation of instrumentation and installation of a radioisotope processing plant. When the reactor is modified we will be able to produce other radioisotopes for applications in nuclear medicine, industry and engineering; at the same time, the safety of the facility will be optimized and the experimental facilities improved

    The SIR-2 experiment, flying on the Indian Chandrayaan-1 mission to the Moon, is a near-infrared point spectrometer of the second-generation built by a European collaboration around the Max-Planck Institute for Solar System Research. SIR-2 has been designed based on the heritage of the SIR Technology experiment on ESA's SMART-1 mission, in order to investigate the mineralogical composition of the Moon for a period of two years. The SIR-2 instrument, which will operate in conjunction with the Indian Hyper-Spectral Imaging spectrometer (HySI) on board Chandrayaan-1, will cover, together with HySi, a combined spectral range of 0.4 to 2.4 m. We will explain the SIR-2 experiment and report on the performance of the instrument during its commissioning phase to deliver high spatial and spectral near-infrared data from its first 100 km polar orbits around the Moon.

    In this paper, a fractional wave equation for the average neutron motion in a nuclear reactor is considered. This representation covers the full spectrum of the average neutron transport behavior, i.e., Fick ian and non-Fick ian effects. The fractional diffusion model retains the main dynamic characteristics of the neutron motion. The relaxation time associated with a rapid variation in the neutron flux contains an adjustable parameter, which can be manipulated to obtain the best representation of the neutron transport phenomena.

    2015-09-01

    En 2011, Mexico won the Colombian international tender for the renewal of instrumentation and control of the IAN-R1 Reactor, to Argentina and the United States. This paper presents the design criteria and the development made for the new digital control system installed in the Colombian nuclear reactor IAN-R1, which is based on a redundant and diverse architecture, which provides increased availability, reliability and safety in the reactor operation. This control system and associated instrumentation met all national export requirements, with the safety requirements established by the IAEA as well as the requirements demanded by the Colombian Regulatory Body in nuclear matter. On August 20, 2012, the Colombian IAN-R1 reactor reached its first criticality controlled with the new system developed at Instituto Nacional de Investigaciones Nucleares (ININ). On September 14, 2012, the new control system of the Colombian IAN-R1 reactor was officially handed over to the Colombian authorities, this being the first time that Mexico exported nuclear technology through the ININ. Currently the reactor is operating successfully with the new control system, and has an operating license for 5 years. (Author)

    By means of Monte Carlo methods, with the code MCNPX, the neutron characteristics of the research nuclear reactor Ian-R1 of Colombia, in power off but with the neutrons source in their start position, have been valued. The neutrons spectra, the total flow and their average power were calculated in the irradiation spaces inside the graphite reflector, as well as in the cells with air. Also the spectra, the total flow and the absorbed dose were calculated in several places distributed along the radial shaft inside the water moderator. The neutrons total flow was also considered to the long of the axial shaft. The characteristics of the neutrons spectra vary depending on their position regarding the source and the material that surrounds to the cell where the calculation was made. (Author)

    William Herschel made the first serious study of 1 Ceres and 2 Pallas in the year 1802. He was moved by their dissimilarities to the other planets to coin a new term to distinguish them. For this purpose he enlisted the aid of his good friends William Watson and Sir Joseph Banks. Watson gave him a long list of possible names, which Herschel rejected. With a lifetime of experience classifying and naming newly found objects in nature, Banks became the man both Erasmus Darwin (in 1781) and William Herschel (in 1802) turned to for sage advice in developing a new descriptive language. In the case of Ceres and Pallas, Banks turned the task over to his friend, the noted philologist Stephen Weston, FRS. It has recently been stated by a noted British historian that it was Weston - not Herschel - who coined the term 'asteroid' to collectively describe Ceres and Pallas. This claim is investigated, and parallels are drawn in the use of neologism in astronomy and botany.

    scattering is much weaker, and this allowed him to develop a method of successive approximation. The material and the calculation are cut up into a series of atomic slices, and the electronic structure solved without approximation in each slice. Being two-dimensional, this was much more manageable than a full three-dimensional calculation. Then the slices could be put together by a sort of perturbation theory to calculate the scattering current as a function of energy along each of the reciprocal lattice 'rods' allowed by the surface periodicity. John didn't just stop at having solved the problem in principle, he also developed a suite of computer codes to do the job in a routine way. He even published the code for all to use, and I believe that to the present day the calculations are still done effectively in the same way. Without the calculations, one cannot interpret the data in terms of a surface atomic structure. Effectively one is doing a computer experiment in parallel to the laboratory experiment, and one fiddles more or less systematically with the surface structure until one gets agreement between the simulations and the laboratory data. One of the things that John noticed was that the process of photoemission (UPS) from a surface is rather similar, and can be calculated in an analogous way. This suddenly became very important because the new synchrotron at Daresbury was about to become operational, pumping out billions of photons for solid state research. Sam Edwards (now Sir Sam) was head of SRC (forerunner of EPSRC) at the time and recognised the problem of interpreting all the data that the machine would provide. And after UPS would come EXAFS, and after that XANES and all the rest of the alphabet soup. With that foresight, unusual at the time, John Pendry was appointed to head the theory group at Daresbury. Previously the theoreticians had revolved around the nuclear physics accelerator, and John had to turn it completely around and refocus it, which he did

We found that about 35% of the tests had at least 1 scoring error. Of SIRS scale scores tallied by examiners, about 8% were incorrectly summed. When the errors were corrected, only 1 SIRS classification was reclassified in the fourfold scheme used by the SIRS. We note that mistallied scores on psychological tests are common, and we review some strategies for reducing scale score errors on the SIRS. (c) 2013 APA, all rights reserved.

    Full Text Available The following essay asks whether art history is still a ‘coy’ science in the sense outlined by Donald Preziosi in his groundbreaking Rethinking Art History of 1989. Surprisingly, the answer is ‘yes,’ because Preziosi’s central point has been largely missed. While most art historians embraced forms of anti-foundationalism and relativism as a response to the ‘crisis of art history,’ Preziosi actually pointed to a deeper problem – the contingency of a disciplinary vantage point at all. In reviewing Preziosi’s critique of art history, and his demonstration of a healthy reflexivity in his work on Aegean art and architecture, it is shown that the proper response to Preziosi’s challenge is to place the act of writing history at the basis of questions of the discipline’s status.

    2011-01-01

    Sir John Charnley (1911-1982), pioneer of the total hip prosthesis, saved countless elderly people from immobility. During the Second World War he assisted Dudley Buxton, orthopaedic surgeon to the British armed forces in the Middle East, in developing new instruments and splints. After the war he first studied healing of bone fractures and the role of compression, and then completely dedicated himself to arthroplasty of the hip. Through countless experiments he found the optimal diameter for the head of the stainless steel prosthesis as well as the optimal polymer for the socket; he also advocated tight cementing of the shaft into the femur. Sir John Charnley received the Lasker Award in 1974 and was knighted in 1977.

  19. SIRS in the Time of Sepsis-3.

    Science.gov (United States)

    Simpson, Steven Q

    2018-01-01

    Severe sepsis is a common, deadly, and diagnostically vexing condition. Recent recommendations for diagnosing sepsis, referred to as consensus guidelines, provide a definition of sepsis and remove the systemic inflammatory response syndrome (SIRS) as a component of the diagnostic process. A concise definition of sepsis is welcomed. However, the approach to developing these guidelines, although thorough, had weaknesses. Emphasis is placed on mortality prediction rather than on early diagnosis. Diagnostic criteria are recommended to replace current criteria without evidence of any effect that their use would have on mortality. SIRS is a prevalent feature of patients with sepsis, should remain an important component of the diagnostic process, and remains a valuable term for discussing patients with life-threatening organ dysfunction caused by infection.

    2018-03-01

    Epidemic phenomena are often modeled in the form of dynamical systems. Such model has also been used to model spread of rumor, spread of extreme ideology, and dissemination of knowledge. Among the simplest is SIR (susceptible, infected and recovered) model, a model that consists of three compartments, and hence three variables. The variables are functions of time which represent the number of subpopulations, namely suspect, infected and recovery. The sum of the three is assumed to be constant. Hence, the model is actually two dimensional which sits in three-dimensional ambient space. This paper deals with the reduction of a SIR type model into two variables in two-dimensional ambient space to understand the geometry and dynamics better. The dynamics is studied, and the phase portrait is presented. The two dimensional model preserves the equilibrium and the stability. The model has been applied for knowledge dissemination, which has been the interest of knowledge management.

    I examine the observational and theoretical researches of William Herschel on 21 comets that he observed over the period 1781 to 1812. Herschel's focus, unlike most contemporaries, was on their physical structure, not their orbits. He forged a strong connection between comets and his nebulae with a scheme of cometary "maturation" (1812) involved a comet traveling from star to star after its central "planetary body'; was born from gravitational collapse of a nebula. During close passages of a star, the comet brightened and lost mass from its atmosphere; at other times, when between stars, it encountered nebulae and was rejuvenated by picking up more mass. Laplace soon adopted these ideas to improve his nebula hypothesis for solar system formation.

    Full Text Available Leishmania donovani, a protozoan parasite is the major causative agent of visceral leishmaniasis. Increased toxicity and resistance to the existing repertoire of drugs has been reported. Hence, an urgent need exists for identifying newer drugs and drug targets. Previous reports have shown sirtuins (Silent Information Regulator from kinetoplastids as promising drug targets. Leishmania species code for three SIR2 (Silent Information Regulator related proteins. Here, we for the first time report the functional characterization of SIR2 related protein 2 (SIR2RP2 of L. donovani.Recombinant L. donovani SIR2RP2 was expressed in E. coli and purified. The enzymatic functions of SIR2RP2 were determined. The subcellular localization of LdSIR2RP2 was done by constructing C-terminal GFP-tagged full-length LdSIR2RP2. Deletion mutants of LdSIR2RP2 were generated in Leishmania by double targeted gene replacement methodology. These null mutants were tested for their proliferation, virulence, cell cycle defects, mitochondrial functioning and sensitivity to known SIR2 inhibitors.Our data suggests that LdSIR2RP2 possesses NAD+-dependent ADP-ribosyltransferase activity. However, NAD+-dependent deacetylase and desuccinylase activities were not detected. The protein localises to the mitochondrion of the promastigotes. Gene deletion studies showed that ΔLdSIR2RP2 null mutants had restrictive growth phenotype associated with accumulation of cells in the G2/M phase and compromised mitochondrial functioning. The null mutants had attenuated infectivity. Deletion of LdSIR2RP2 resulted in increased sensitivity of the parasites to the known SIR2 inhibitors. The sirtuin inhibitors inhibited the ADP-ribosyltransferase activity of recombinant LdSIR2RP2. In conclusion, sirtuins could be used as potential new drug targets for visceral leishmaniasis.

    To assess the clinical and demographic profile of Systemic Inflammatory Response Syndrome (SIRS) and sepsis, among newly admitted children in different age groups in a hospital in North India. This prospective study was conducted at a referral care centre in Northern India. All children, age group 0 to SIRS) and sepsis and to gain clinical and demographic data. The criteria laid at International consensus conference, 2002, were used to define patients as SIRS, Sepsis, Severe sepsis and Septic shock. During the study period, a total of 865 patients were screened for SIRS. Prevalence of SIRS amongst hospitalised children was 23 % (n = 201). Seventy nine percent (n = 159) of patients had infection associated SIRS and 21 % (42) had non-infective SIRS. Sixty four percent (n = 129) SIRS patients had uncomplicated sepsis, 15 % (n = 30) patients fulfilled criteria for severe sepsis. Out of the latter 30, 19 had septic shock. Organ dysfunction in SIRS was noted in 25 % (n = 51). 37.25 % (n = 19) had multiple organ dysfunction syndrome (MODS). The most common organism isolated was Staphylococcus aureus (n = 9). Focus of infection in majority was pulmonary (44 %). Mean duration of antibiotic therapy and hospital stay in the SIRS group were 6.4 and 6.5 d respectively. In the group without SIRS, mean duration were 2.44 d and 3.07 d respectively The differences were statistically significant. In conclusion, the proportion of sepsis contributing to SIRS is high in a tertiary care hospital. Therefore rapid recognition of SIRS is essential. Goal directed treatment of sepsis is also important so that high mortality associated with severe sepsis and septic shock are prevented.

    SIR-2 is an upgraded, compact grating, near-infrared spectrometer, which covers the wave-length range between 0.9 and 2.45 μ m, with a spectral resolution of Δ λ pixel = 6 nm. SIR-2 has been chosen to fly on board the Indian mission Chandrayan-1 in 2007-2009. SIR-2, which will benefit from its heritage of SIR on SMART-1, will deliver, compared to SMART-1, a homogenous lunar surface coverage with unsurpassed spatial resolution and thus will greatly improve our knowledge of the lunar surface composition. The SIR-2 NIR data, combined with the hyperspectral data from the HySI instrument on Chandrayaan-1, will provide, for the first time, a full spectral coverage of the olivine and large part of the pyroxen bands, thus allowing one to extract from the data the necessary input parameters for the mineralogical mixing models. We present the SIR-2 design and discuss the potential science.

    En 2011, Mexico won the Colombian international tender for the renewal of instrumentation and control of the IAN-R1 Reactor, to Argentina and the United States. This paper presents the design criteria and the development made for the new digital control system installed in the Colombian nuclear reactor IAN-R1, which is based on a redundant and diverse architecture, which provides increased availability, reliability and safety in the reactor operation. This control system and associated instrumentation met all national export requirements, with the safety requirements established by the IAEA as well as the requirements demanded by the Colombian Regulatory Body in nuclear matter. On August 20, 2012, the Colombian IAN-R1 reactor reached its first criticality controlled with the new system developed at Instituto Nacional de Investigaciones Nucleares (ININ). On September 14, 2012, the new control system of the Colombian IAN-R1 reactor was officially handed over to the Colombian authorities, this being the first time that Mexico exported nuclear technology through the ININ. Currently the reactor is operating successfully with the new control system, and has an operating license for 5 years. (Author)

    By means of Monte Carlo methods, with the code MCNPX, the neutron characteristics of the research nuclear reactor Ian-R1 of Colombia, in power off but with the neutrons source in their start position, have been valued. The neutrons spectra, the total flow and their average power were calculated in the irradiation spaces inside the graphite reflector, as well as in the cells with air. Also the spectra, the total flow and the absorbed dose were calculated in several places distributed along the radial shaft inside the water moderator. The neutrons total flow was also considered to the long of the axial shaft. The characteristics of the neutrons spectra vary depending on their position regarding the source and the material that surrounds to the cell where the calculation was made. (Author)

    A study was conducted to monitor reproductive of lactating Holstein Fries ian cows by measuring milk progesterone levels. Sequential post-partum milk samples were collected weekly throughout 20 weeks after pregnancy. Progesterone concentrations were determined by solid phase RIA. Lactating cows required an average of 5.2 weeks to resume luteal activity; 48% of the cows conceived after first insemination and had significantly high progesterone concentrations during the first 5 weeks after insemination than cows which returned to heat 5-8 weeks after insemination> Results also revealed that adequate level of progesterone, which varied between 4.2 and 9.1 nmol/l, is required to maintain early pregnancy and progesterone level remains high in pregnant cows.

  11. Concepts, Diagnosis and the History of Medicine: Historicising Ian Hacking and Munchausen Syndrome.

    Science.gov (United States)

    Millard, Chris

    2017-08-01

    Concepts used by historians are as historical as the diagnoses or categories that are studied. The example of Munchausen syndrome (deceptive presentation of illness in order to adopt the 'sick role') is used to explore this. Like most psychiatric diagnoses, Munchausen syndrome is not thought applicable across time by social historians of medicine. It is historically specific, drawing upon twentieth-century anthropology and sociology to explain motivation through desire for the 'sick role'. Ian Hacking's concepts of 'making up people' and 'looping effects' are regularly utilised outside of the context in which they are formed. However, this context is precisely the same anthropological and sociological insight used to explain Munchausen syndrome. It remains correct to resist the projection of Munchausen syndrome into the past. However, it seems inconsistent to use Hacking's concepts to describe identity formation before the twentieth century as they are given meaning by an identical context.

    Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. Later, the diagnosis was confirmed by genetic analysis. This female is the oldest living patient with Williams syndrome in Hungary. Orv Hetil. 2017; 158(47): 1883-1888.

  15. Differences between Structured Interview of Reported Symptoms (SIRS) and SIRS-2 sensitivity estimates among forensic inpatients: A criterion groups comparison.

    Tarescavage, Anthony M; Glassmire, David M

    2016-10-01

    The Structured Interview of Reported Symptoms (SIRS) underwent a major revision in 2010 yielding the SIRS-2. The new test has since been criticized for several potential problems, particularly in terms of its sensitivity to feigned psychopathology. For this reason, the purpose of this study was to examine the concordance between SIRS and SIRS-2 classifications and sensitivity estimates in an archival sample of 263 criminal defendants (215 males, 48 females) who were admitted to a high-security state psychiatric hospital for restoration of competency to stand trial. In a subgroup of 39 presumed feigning patients who elevated 1 or more collateral measures of feigning (primarily the M-FAST) at conservative cutoffs, we found marked discrepancies between the sensitivity of the SIRS (.87) and SIRS-2 (.54). The marked differences in sensitivity were partially explained by a global interpretation discordance rate of 47%, with discordance primarily resulting from SIRS-based feigning cases being classified as indeterminate on the SIRS-2. Follow-up analyses of intercorrelations and percentile distributions indicated that the new SIRS-2 scales may lack utility in the assessment of feigning because of problems relating to the construct validity of the scales and their interpretive cutoffs. Future directions in research and clinical practice are discussed, with added emphasis on the significant limitations of archival pretrial forensic samples for identifying presumed genuine groups necessary to calculate specificity estimates (which were meaningfully higher for the SIRS-2 in this sample). Overall, the primary clinical implication is that feigning should remain a strong consideration in SIRS-2 cases yielding an indeterminate classification.

    In sepsis, dysregulation of the immune response leads to rapid multiorgan failure and death. Accurate and timely diagnosis is lifesaving and should discriminate sepsis from the systemic inflammatory response syndrome (SIRS) caused by non-infectious agents. Osteopontin acts as an extracellular matrix component or a soluble cytokine in inflamed tissues. Its exact role in immune response and sepsis remains to be elucidated. Therefore, we investigated the role of osteopontin in SIRS and sepsis. Prospective, observational study. Intensive care unit of a university hospital. Fifty-six patients with SIRS or sepsis and 56 healthy subjects were enrolled. We analyzed the serum levels of osteopontin and TH1-TH2 cytokines and investigated the role of osteopontin on interleukin 6 secretion by monocytes. Serum osteopontin levels were strikingly higher in patients than in controls and in sepsis than in SIRS, and decreased during the resolution of both the disorders. Receiver operating characteristic curves showed that osteopontin levels have discriminative power between SIRS and sepsis with an area under the curve of 0.796. Osteopontin levels directly correlated with those of interleukin 6 and in vitro, recombinant osteopontin increased interleukin 6 secretion by monocytes in both the absence and presence of high doses of lipopolysaccharide. These data suggest that osteopontin might be a mediator involved in the pathogenesis of SIRS and sepsis, possibly by supporting interleukin 6 secretion. 45. SIRS/Sepsis: clinical studies.

  20. The Relationship between History and Ethics in Ian McEwan’s Black Dogs

    Directory of Open Access Journals (Sweden)

    Maryam Sedaghat

    2014-06-01

    Full Text Available The relationship between history and ethics may seem irrelevant at first; however, these two have been related during the long history of war, violence and mass killing. The need of history to ethics is for saving itself from all the violence and terror. Emmanuel Levinas as a philosopher has tried to define ethics in a way that suits the terrible historical condition of humanity in the twentieth century. In his view, ethics is the infinite responsibility towards other human beings. He defines ‘being’ in relation to the ‘other’ who may be a complete stranger. In this definition a person bears complete responsibility toward the other and should answer the other’s call for help. In Ian McEwan's novel Black Dogs the protagonist is exposed to historical legacies of violence, and develops an ethical consciousness until the end of the novel. Responsibility seems to be a good answer to historical mass killing and violence that is dominant in the world.

    Psychologists are faced with formidable challenges in making their assessment methods relevant to growing numbers of Hispanic clients for whom English is not the primary or preferred language. Among other clinical issues, the determination of malingering has profound consequences for clients. In this investigation, we evaluated a Spanish translation of the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) with 80 Spanish-speaking Hispanic American outpatients. Using a between-subjects simulation design, the Spanish SIRS was found to produce reliable results with small standard errors of measurement. Regarding validity, very large effect sizes (mean Cohen's d= 2.00) were observed between feigners and honest responders for the SIRS primary scales. We consider the potential role of the Spanish SIRS with reference to Spanish translations for other assessment instruments.

    Previous examination in a small number of individuals with Williams syndrome (also referred to as Williams-Beuren syndrome) has shown subtly softer skin and reduced deposition of elastin, an elastic matrix protein important in tissue recoil. No quantitative information about skin elasticity in individuals with Williams syndrome is available; nor has there been a complete report of dermatologic findings in this population. To fill this knowledge gap, 94 patients with Williams syndrome aged 7-50 years were recruited as part of the skin and vascular elasticity (WS-SAVE) study. They underwent either a clinical dermatologic assessment by trained dermatologists (2010 WSA family meeting) or measurement of biomechanical properties of the skin with the DermaLab™ suction cup (2012 WSA family meeting). Clinical assessment confirmed that soft skin is common in this population (83%), as is premature graying of the hair (80% of those 20 years or older), while wrinkles (92%), and abnormal scarring (33%) were detected in larger than expected proportions. Biomechanical studies detected statistically significant differences in dP (the pressure required to lift the skin), dT (the time required to raise the skin through a prescribed gradient), VE (viscoelasticity), and E (Young's modulus) relative to matched controls. The RT (retraction time) also trended longer but was not significant. The biomechanical differences noted in these patients did not correlate with the presence of vascular defects also attributable to elastin insufficiency (vascular stiffness, hypertension, and arterial stenosis) suggesting the presence of tissue specific modifiers that modulate the impact of elastin insufficiency in each tissue. © 2014 Wiley Periodicals, Inc.

    In "Dove Cottage", the old house of the poet laureate William Wordsworth (1770-1850) in Grasmere, England, there is a portrait of Sir Humphry Davy (1778-1829). In 1804, Wordsworth invited his young friend to his home. Davy's works in the field of chemistry are well known. Interestingly enough, once he wished he could be a poet. His future seemed to be prosperous and delightful. He was highly evaluated by Robert Southey, poet laureate. But he has chosen the way of chemist. The author found some facts from literatures and received some information by courtesy of the Wordsworth Trust, Centre for British Romanticism. Davy's life and his works were introduced chronologically.

  6. Sex Complexity and Politics in Black Dogs by Ian McEwan

    Science.gov (United States)

    Abbasiyannejad, Mina; Talif, Rosli

    Ian McEwan's Black Dogs (BD) is a story of socio-political conflict during the critical era of the Cold War. Black Dogs is riddled with party (political) domination and its outcomes in society. Europe is still suffering the consequences of the Second World War, perhaps the biggest war of the twentieth century. In the aftermath of such worldwide upheaval, the conflicts that were in tandem with the scramble for political domination emerged in diverse ways, affecting nations and their human populations. Systematic sexual assault during the war years showed that sex was used both for intimidation and humiliation. This study attempts to picture the multidimensional aspects of politics which are practically related to the most intimate human relationship, that is, sex. It pictures how personal is equated with the political and vice versa. The theory of sexual politics is the theoretical framework used to scrutinize power-structure relationship. By reviewing the major conflicts in such a scenario, as the Cold War, and societal restriction, this study concludes that conflict in the macrocosm (world and society) affects the microcosm (individual) in McEwan's Black Dogs. It provides a rather broad picture of politics and sexuality and highlights the stresses of wider society on human dysfunctional relationships. Rape as a tactic of war for a political goal demonstrates another aspect of sex. Reviewing the period in which the story takes place and relating it to the conflicts in society, the study goes beyond simple cause and effect problems among individuals and portrays a holistic view of sexuality and society.

    Full Text Available Over the past decade, sepsis has been diagnosed according to consensus guidelines established in 1991 as an infection in addition to the symptoms of systemic inflammatory response syndrome (SIRS. In addition to the previous criteria, the 2001 conference added several new diagnostic criteria for sepsis. Of particular interest was the inclusion of the biomarkers procalcitonin (PCT and C-reactive protein (CRP, despite the overall conclusion that it was premature to use biomarkers for sepsis diagnosis. The primary recommendation of the panel was the implementation of the Predisposition, insult Infection, Response, and Organ dysfunction (PIRO.The immune system has traditionally been devided into innate and adaptive components, each of which has a different role and function in defending the host against infectious agents. Stimulation of different TLRs induces distinct patterns of gene expression, which not only leads to the activation of innate immunity but also increasing evidence supports an additional critical role for TLRs in orchestrating the development of adaptive immune responses. The superantigens are able to induce toxic shock syndrome and can sometimes cause multiple organ failure via adaptive immune system. The superantigenic activity of the bacterial exotoxins can be attributed to their ability to cross-link major histocompatibility complex class II molecules on antigen-presenting cells outside the peptide groove with T-cell receptors to form a trimolecular complex. This trimolecular interaction leads to uncontrolled release of a number of proinflammatory cytokines. Proinflammatory cytokines especially IFN-γ and TNF-α, the key cytokines causing toxic shock syndrome. KEYWORDS: sepsis, innate immunity, adaptive.

    Systemic Inflammatory Response Syndrome (SIRS) and sepsis remain leading causes of death. Despite many similarities, the two entities are very distinct clinically and immunologically. T-Lymphocytes play a key pivotal role in the pathogenesis and ultimately outcome following both SIRS and sepsis. Integrins are essential in the trafficking and migration of lymphocytes. They also serve vital roles in efficient wound healing and clearance of infections. Here, we investigate whether integrin expression, specifically β1 (CD29) and β2 (CD18), are disrupted in SIRS and sepsis, and assess differences in integrin expression between these two critically ill clinical categories. T-Lymphocytes were isolated from whole blood collected from ICU patients exhibiting SIRS or sepsis. Samples were analyzed for CD18 (β2) and CD29 (β1) on CD3 + T cells through flow cytometry. Septic patients were stratified into either exclusively abdominal or non-abdominal sources of sepsis. CD18 was almost ubiquitously expressed on CD3 + T cells irrespective of clinical condition. However, CD29 (β1 integrin) was lowest in SIRS patients (20.4% of CD3 + T cells) when compared with either septic patients (35.5%) or healthy volunteers (54.1%). Furthermore, there was evidence of compartmentalization in septic patients, where abdominal sources had a greater percentage of CD3 + CD29 + T cells (41.7%) when compared with those with non-abdominal sources (29.5%). Distinct differences in T-cell integrin expression exists between patients in SIRS versus sepsis, as well as relative to the source of sepsis. Further work is needed to understand cause and effect relative to the progression from SIRS into sepsis.

    By the end of his career, Sir William Broadbent (1835-1907) had become an eminent London general physician who had been appointed Physician-in-Ordinary to King Edward VII and to the Prince of Wales. Previously he had been Physician-in-Extraordinary to Queen Victoria. At earlier stages in his professional life, he had played a significant role in the development of clinical neurology in Victorian-era Britain. In 1866, he had enunciated a principle (Broadbent's hypothesis) that for the first time satisfactorily accounted for the mechanisms by which the trunk and bulbar muscles and the upper face were spared in hemiplegia. He had also carried out original investigations into the distribution of fiber tracts in the human cerebral hemispheres. At intervals over the years, he published on aspects of aphasia and developed a rather complicated though logical conceptual schema of the presumed anatomical background to the process of speech, based on clinic-pathological correlations. His role in all this neurological research and his other contributions on subjects such as neurosyphilis have largely been forgotten by subsequent generations.

    Public discourse concerning current vaccination recommendations has dramatically increased. The current battle is not new, having had a lengthy foreshadowing during the 19th and early 20th centuries. Over a 30-year period, a concerted effort to limit the use of smallpox vaccine grew at the very time typhoid vaccines were being developed and advocated for widespread prevention. As a long time advocate for widespread smallpox vaccination and a supporter of the newly tested typhoid vaccine, Sir William Osler entered the public debate at the beginning of World War I. Osler was asked to address the officers and men in the British army on the need for typhoid vaccination. His speech entitled "Bacilli and Bullets" outlined the medical reasons for getting inoculated against typhoid. Osler's strong support for typhoid vaccination of the British troops was met by opposition in Parliament but not by most of the troops. Osler's arguments in support of vaccination failed to respond to the concept of "conscientious objection," which was central to the antivaccinationists' argument. Similar arguments are being propounded by current antivaccination groups.

    Systemic inflammatory response syndrome (SIRS) is a clinical syndrome following inflammation. Clinically, it is difficult to distinguish SIRS following an infection, i.e., sepsis, from non-infectious SIRS. Myeloperoxidase is a hemeprotein stored in the neutrophil azurophilic granules and is one of the main pillars of neutrophil attack. Therefore, we hypothesized that myeloperoxidase can differentiate between sepsis and non-infectious SIRS in patients with systemic inflammatory response syndrome in the intensive care unit (ICU). An observational single-center cohort study was conducted measuring myeloperoxidase in patients with SIRS in the first 48 h after admission. The outcomes were established using predefined definitions. Thirty-day mortality was retrospectively assessed. We found significantly higher levels of myeloperoxidase in patients with sepsis and septic shock compared to patients without sepsis (60 ng/ml versus 43 ng/ml, P = 0.002). Myeloperoxidase levels were related to 30-day mortality (P = 0.032), and high MPO levels on top of a high APACHE IV score further increased mortality risk. We show that myeloperoxidase is a potentially novel biomarker for sepsis in the ICU. Myeloperoxidase could eventually help in diagnosing sepsis and predicting mortality. However, more research is necessary to confirm our results.

    Due to the obsolescence of the instrumentation and control system of the nuclear research reactor IAN-R1, the Institute of Geology and Mining of Colombia, IngeoMinas, launched an international convoking for renewal it which was won by the Instituto Nacional de Investigaciones Nucleares (ININ). Within systems to design, the reactor protection system is described as important for safety, because this carried out, among others two primary functions: 1) ensuring the reactor shutdown safely, and 2) controlling the interlocks to protect against operational errors if defined conditions have not been met. To fulfill these functions, the various subsystems related to the safety report the state in which they are using binary signals and are connected to the inputs of two redundant logic wiring circuits called action logics (Al) that are part of the reactor protection system. These Al also serve as logical interface to indicate at all times the status of subsystems, both the operator and other systems. In the event that any of the subsystems indicates a state of insecurity in the reactor, the Al generate signals off (or scram) of the reactor, maintaining the interlock until the operator sends a reset signal. In this paper the design, implementation, verification and testing of circuits that make up the Al 1 and 2 of IAN-R1 reactor is described, considering the fulfillment of the requirements that the different international standards imposed on this type of design.

    A large amount of research demonstrates the importance of key interventions in reducing mortality rates of pediatric patients with sepsis (Dellinger et al., 2008). Assessment and recognition of declining status must occur for interventions to be initiated. Of health care practitioners, nurses typically spend the most time with patients, and they must be knowledgeable in recognizing the systemic inflammatory response syndrome and sepsis while also being aware of the importance of prompt intervention. The literature does not discuss pediatric nurses' knowledge of systemic inflammatory response syndrome (SIRS)/sepsis recognition. The purpose of this study was to assess the knowledge of acute and critical care pediatric nurses of SIRS diagnostic criteria, sepsis guidelines, and the importance of SIRS recognition. This cross-sectional, quantitative, correlational descriptive study included 242 acute and critical care pediatric nurses at a 490-bed urban pediatric hospital. Participants completed an original questionnaire with face and content validity regarding SIRS criteria, sepsis guidelines, priority interventions, and attitude toward the importance of SIRS recognition. Findings demonstrated a significant knowledge deficit among participants in several key areas of SIRS/sepsis recognition. The mean score was 60.8% ± 7.4%. Item analyses demonstrated nurses easily recognize septic shock but have difficulty recognizing patients in earlier stages of the sepsis continuum. Significant confusion was evident regarding the role of blood pressure and serum lactic acid levels in diagnosing sepsis. It is recommended that an educational intervention be created for acute and critical care pediatric nurses to aid them in recognizing sepsis in its earlier stages.

    The point spectrometer SIR-2 on Chandrayaan-1 provided radiance spectra integrated over circular footprints of 200 m diameter in the wavelength range 934-2410.8 nm in 256 channels [1]. To analyze SIR-2 reflectance spectra in their spatial context, a coregistration to Chandrayaan-1 M³ hyperspectral images [2] as well as a correction for topography and thermal emission are inevitable. The thermal and topographic correction procedure is based on the surface temperature and a digital elevation model (DEM) inferred from M³ data. The corrected reflectance spectra are then normalized to a standard illumination and viewing geometry.

    Full Text Available The development of tourism is a significant aspect of the processes of modernity in the High Arctic. This article discusses the British art historian and mountaineer Sir William Martin Conway's two travelogues, The First Crossing of Spitsbergen (1897 and With Ski and Sledge over Arctic Glaciers (1898, in terms of a pioneering tourist approach to the archipelago of Svalbard. Unlike earlier yachting tourists, Conway described a journey into the uncharted interior of the main island, Spitsbergen. His books are therefore narrated as exploration accounts and following many of the demands of that genre, such as an emphasis on mapping, natural science and being the first. However, they may also be read as guidebooks for other discerning and undaunted British gentleman travellers. Inspired by the art critic John Ruskin’s “science of aspects”, which combined accurate scientific observations and practical knowledge with an imaginative and aesthetic response to the landscape, Conway attempts to give his readers a positive sense of the qualities of the Arctic. At the same time, he promotes Svalbard as an Arctic “Playground of Europe”, where adventurous Alpinists in addition to climbing unknown mountains and glaciers could find fraternal domesticity far away from home around the hearth of the campfire. In this way Conway locates natural beauty, life and recreational opportunities where travellers before him had only described desolation and death.

  19. Sir Victor Horsley (1857-1916) and the birth of English neurosurgery.

    2007-02-01

    Modern surgery developed in the second half of the 19th century, at the end of which neurosurgery was established as a profitable region of operative intervention. In the British Isles, the first exponent was Sir William Macewen (1848-1924) in Glasgow. But neuroscience had advanced in London due to the excellence of the neurologists in the several hospitals there. Foremost among English neurosurgeons was Victor Horsley whose career had a worldwide influence on the speciality. Initially, operations were carried out for cranial trauma, the removal of displaced bone or blood clot, and the drainage of abscesses arising from infection of the middle ears and air sinuses. The diagnosis of brain and spinal tumours by neurologists encouraged removal by surgeons, of which Horsley was among the earliest. Horsley performed many operations on animals, experiments opposed by the anti-vivisectionists whose campaigns Horsley countered. Horsley had many other interests, some of which displeased the establishment, and in World War I his experience in neurosurgery was not used. He served as a general surgeon, visiting Egypt, India and Mesopotamia where, in Amara, he died from hyperpyrexia complicating bacillary dysentery.

  20. The Systemic Inflammatory Response Syndrome (SIRS) in acutely hospitalised medical patients: a cohort study.

    Sepsis is an infection which has evoked a systemic inflammatory response. Clinically, the Systemic Inflammatory Response Syndrome (SIRS) is identified by two or more symptoms including fever or hypothermia, tachycardia, tachypnoea and change in blood leucocyte count. The relationship between SIRS symptoms and morbidity and mortality in medical emergency ward patients is unknown. We conducted a prospective cohort study of the frequency of SIRS and its relationship to sepsis and death among acutely hospitalised medical patients. In 437 consecutive patients, SIRS status, blood pressure, infection and comorbidity on admission was registered together with 28-day mortality. A hundred and fifty-four patients (35%) had SIRS on admission, 211 patients (48%) had no SIRS, and 72 patients (16%) had insufficient data to evaluate their SIRS status. SIRS patients were 2.2 times more frequently infected, with 66/154 SIRS patients versus 41/211 non-SIRS patients: p SIRS patients with 15/154 SIRS patients versus 3/211 non-SIRS patients: p = 0.001, RR 6.9 (95% CI 2.0-23.3). Most of the deaths among patients with SIRS occurred among patients with malignant conditions. Septic shock developed in 4/154 (3%) of the patients with SIRS, whereas this occurred in only one of the 211 patients (0.5%) without SIRS on arrival: p = 0.08, RR 5.5 (95% CI 0.6-48.6). We found SIRS status on admission to be moderately associated with infection and strongly related to 28-day mortality.

    Williams syndrome is a genetic neurodevelopmental disorder characterized by an uncommon hypersociability and a mosaic of retained and compromised linguistic and cognitive abilities. Nearly all clinically diagnosed individuals with Williams syndrome lack precisely the same set of genes, with breakpoints in chromosome band 7q11.23 (refs 1-5). The contribution of specific genes to the neuroanatomical and functional alterations, leading to behavioural pathologies in humans, remains largely unexplored. Here we investigate neural progenitor cells and cortical neurons derived from Williams syndrome and typically developing induced pluripotent stem cells. Neural progenitor cells in Williams syndrome have an increased doubling time and apoptosis compared with typically developing neural progenitor cells. Using an individual with atypical Williams syndrome, we narrowed this cellular phenotype to a single gene candidate, frizzled 9 (FZD9). At the neuronal stage, layer V/VI cortical neurons derived from Williams syndrome were characterized by longer total dendrites, increased numbers of spines and synapses, aberrant calcium oscillation and altered network connectivity. Morphometric alterations observed in neurons from Williams syndrome were validated after Golgi staining of post-mortem layer V/VI cortical neurons. This model of human induced pluripotent stem cells fills the current knowledge gap in the cellular biology of Williams syndrome and could lead to further insights into the molecular mechanism underlying the disorder and the human social brain.

    1996-10-01

    1996 may be marked as a transitional year in the study of Williams syndrome (WS), when the causes of this complex condition and a practical way to investigate began to come into focus. WS presents a remarkable collection of symptoms that affect blood vessels, growth, intelligence, and behavior. WS commonly leads to infantile hypercalcemia, retardation of growth, prematurely wrinkled skin, supraventricular aortic stenosis (SVAS), and sensitivity to loud noise. Children with this condition are often mentally retarded, with distinctive {open_quotes}elfin{close_quotes} facial features, a hoarse voice, and an {open_quotes}engaging{close_quotes} personality. Their cognitive deficits may be minimal or profound but typically involve a specific pattern of strengths and weaknesses, with better-than-average face recognition but little ability to recognize how parts of patterns that they see fit into a whole. 36 refs.

    In the present study 37 patients with surgical infection were investigated and a new set of diagnostic tests for detection of major syndromes of systemic inflammation - systemic inflammatory response syndrome (SIRS), compensatory anti-inflammatory response syndrome (CARS) and mixed antagonist response syndrome (MARS) - was developed. In summary, we have demonstrated that patients with surgical infection were characterized by an immunodeficiency with significant reduction of mitogen-induced proliferation and IL-2/IL-4 production in vitro combined with decrease of HLA DR(+) monocytes. Furthermore, it was revealed that the patient's serum exhibited substantially enhanced suppressive and inflammatory activities as well as the level of C-reactive protein. We have defined the negative correlation between the serum inflammatory and suppressive activities (SIA and SSA) that was most prominent at the early stage of disease. Since the changes of serum bioactivity in the course of surgical infection were prominent and coherent, we supposed that tested activities might reflect the distinctive features of systemic inflammation. In according to this assumption, the patients were divided into 3 subgroups with predominance of SIRS, CARS and MARS by using the SIA and SSA expression. It has been shown that SIRS was more frequently detected at the early stage, whereas CARS - at the late stage of disease. Patients with SIRS, CARS or MARS significantly differed by the content of CD8(+) T and CD72(+) B lymphocytes, the concentration of IgG and IgA, the production of IL-2 and IL-4. Finally, the data obtained from patients, those were studied repeatedly, showed the possibility of transformation of the major systemic inflammatory syndromes during the disease course. Our findings suggest that measurement of serum inflammatory and suppressive activities may help to differentiate patients with SIRS, CARS or MARS and to select the appropriate strategy of immunotherapy.

    The objectives of this study were to evaluate the efficacy of additional cone beam computed tomography (CBCT) imaging on decreasing the risk of inferior alveolar nerve (IAN) injury during third molar removal in patients at high risk and to assess the surgical outcomes. The study sample included patients considered at high risk for IAN injury based on panoramic radiography (PAN) evaluation. The primary predictor was the type of imaging method (PAN only or with additional CBCT). The other variables were demographic and anatomical/radiographic factors. The primary outcome variable was IAN injury. The secondary outcome variables were the preoperative surgical plan and surgical results including IAN exposure and duration of surgery. The sample comprised 122 patients (139 teeth) aged 18-48 years. Postoperative temporary IAN injury was present in three (4.2%) cases in the CBCT group and 11 (16.4%) in the PAN group at 7 days after surgery. However, none of the patients had a permanent IAN injury at the 6-month follow-up. Additional CBCT imaging was not superior to PAN in reducing IAN injury after third molar surgery during long-term follow-up. Nonetheless, CBCT may decrease the prevalence of temporary IAN injury and improve the surgical outcomes in high-risk patients.

The interview addresses many different questions including why Williams became an astronaut, and the events that led to his interest. Other interesting information that this one-on-one interview discusses is his reaction to and the reasons for the change of the mission objectives. Williams also mentions the scheduled space-walk that he will perform, docking with the International Space Station (ISS), the repairs of equipment, and the change of the batteries.

  20. Comparability of Structured Interview of Reported Symptoms (SIRS) and Structured Interview of Reported Symptoms-Second Edition (SIRS-2) Classifications With External Response Bias Criteria.

    2018-02-01

    Rogers, Sewell, and Gillard (2010) released a revised version of the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992), the SIRS-2, which introduced several new scales, indices, and a new classification model with the overall goal of improving its classification of genuine versus feigned presentations. Since the release of the SIRS-2, several concerns have been raised regarding the quality of the SIRS-2 development and validation samples and the method used to calculate classification accuracy estimates. To further explore issues related to the clinical utility of the SIRS-2, the current study examined associations of the SIRS and SIRS-2 with the Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008/2011) validity scales in separate samples of disability claimants and criminal defendants. Results indicate that the SIRS-2 reduced the number of feigning classifications. Additional analyses suggest that the Modified Total Index and Supplementary Scale Index do not assess the test-taking strategy that Rogers and colleagues (2010) intended the indices to capture. External data indicates that evaluees reclassified on the SIRS-2 in nonfeigning categories exhibited feigned symptoms of psychopathology. Indeed, we found that SIRS-identified feigners showed significant evidence of overreporting on the Minnesota Multiphasic Personality Inventory-2-Restructured Form validity scales, regardless of their SIRS-2 classification. The current study highlights the overall weakness in clinical utility of the SIRS-2. Implications of these results for both clinical and forensic settings are discussed.

  1. Likelihood of obtaining Structured Interview of Reported Symptoms (SIRS) and SIRS-2 elevations among forensic psychiatric inpatients with screening elevations on the Miller Forensic Assessment of Symptoms Test.

    2016-12-01

    The Miller Forensic Assessment of Symptoms Test (M-FAST) was designed as a screening measure for feigned psychiatric symptoms. When M-FAST Total Scores are elevated (raw score ≥6), the test manual recommends follow-up with a more comprehensive measure of feigning, such as the widely used and researched Structured Interview of Reported Symptoms (SIRS) or the revised version of the test (SIRS-2). The purpose of the current study was to evaluate how often M-FAST screening elevations are associated with subsequent elevations on the SIRS or SIRS-2. The sample included archival data from 100 forensic psychiatric inpatients who obtained M-FAST Total Score elevations ≥6 during screening and were subsequently administered the SIRS (that was also rescored using SIRS-2 criteria). Among examinees who elevated the M-FAST over the recommended cutoff, 66.0% met standard SIRS feigning criteria, 42% met SIRS-2 criteria for feigning, and 81.0% obtained at least 1 SIRS/SIRS-2 elevation in the Probable Feigning range or higher. These results are consistent with the M-FAST manual guidelines, which support the use of the ≥6 M-FAST cutoff score to screen for potential feigning (but not as an independent marker of feigning). A higher M-FAST cutoff score of ≥16 was associated with subsequently meeting full SIRS criteria for feigning in 100.0% of protocols. Because the SIRS criteria were designed to have very low false positive rates, these findings indicate that more confident assertions about feigning can be made when elevations reach this level on the MFAST.

    Systemic inflammatory response syndrome (SIRS) is frequently observed after various types of acute cerebral injury and has been linked to clinical deterioration in non-traumatic brain injury (TBI). SIRS scores have also been shown to be predictive of length of stay and mortality in trauma patients. We aimed to determine the prognostic utility of SIRS present at admission in trauma patients with isolated TBI. This was a 5-year retrospective cohort study of adults (≥18 years) with isolated TBI admitted to a Level II trauma center. The prognostic value of SIRS, total SIRS scores, and each SIRS criterion was examined by Χ 2 and logistic regression analyses. Of the 330 patients identified, 50 (15.2%) met SIRS criteria. SIRS was significantly associated with poor outcome (P SIRS score of 2 on admission (P = 0.007) and increased significantly to 6.5 times in patients with a SIRS score of 3 (P = 0.002). Logistic regression demonstrated SIRS and each criterion to be significant independent prognostic factors (SIRS, P = 0.030; body temperature, P = 0.006; tachypnea, P = 0.022, tachycardia P = 0.023). SIRS at admission is an independent predictor of poor outcome in isolated TBI patients. These data demonstrate SIRS to be an important clinical tool that may be used in facilitating prognostication, particularly in elderly trauma patients. Future prospective studies aimed at therapeutic interventions to mitigate SIRS in TBI patients are warranted. Prognostic, Level III.

    Full Text Available Ian McEwan's On Chesil Beach is the story of conflicts at various levels. In this novella, the author shows how different factors, particularly cultural norms and sexual conflicts can affect people's lives and lead them down a certain path. Using a hermeneutic approach, this paper discusses the influential socio-economic, political, and cultural factors that had great impact on people's lives. McEwan illustrates how circumstances and settings influence people’s livelihoods and how the socio-economic status of the characters plays an important role in determining their future conditions. This essay shows the influence of culture, including the social climate of the time, on the society's attitudes towards sexuality, class differences, legislation, contraceptives, abortion and—most of all—on the personal lives of the characters in On Chesil Beach.

Latar belakang sosial Seno yang sekaligus sebagai wartawan melemparkan gagasan kritisnya terkait kondisi difabel yang masih mendapat stigma negatif dari masyarakat. Cerminan sosial dalam novel tidak jauh berbeda dengan realitas yang terjadi di Indonesia, dimana ideologi kenormalan menyumbangkan berbagai bentuk ketidakadilan terhadap difabel. Difabel masih dianggap sebagai individu yang cacat, sebagai kutukan Tuhan, dan sebagai sumber aib bagi keluarga. Pendobrakan terhadap realitas yang ada, dilakukan pengarang lewat tokoh utama “Aku” yang difabel dengan menyajikan fakta bahwa difabel memiliki kemampuan yang berbeda, tetapi masyarakat masih belum memahaminya karena sudah terlanjur terjebak pada stigma negatif terhadap difabel.

  5. William Band at Yenching University

    2008-04-01

    William Band (1906-1993) has been widely remembered by his American colleagues and students as ``a fine physicist and teacher,'' who taught at Washington State University in Pullman between 1949 and 1971 and authored Introduction to Quantum Statistics (1954) and Introduction to Mathematical Physics (1959). Not many, however, knew much about Band's early career, which was very ``uncommon and eventful.'' Born in England, Band graduated from University of Liverpool in 1927 with an MsSc degree in physics. Instead of pursuing his Ph.D. at Cambridge, he chose to teach physics at Yenching University, a prestigious Christian university in Beijing, China. Arriving in 1929, Band established his career at Yenching, where he taught and researched the theory of relativity and quantum mechanics, pioneered the study on low-temperature superconductivity in China, founded the country's first graduate program in physics, and chaired the Physics Department for 10 years until he fled from Yenching upon hearing of the attack on Pearl Harbor. It took him two years to cross Japanese occupied areas under the escort of the Communist force; he left China in early 1945. This presentation will explore Band's motivation to work in China and his contributions to the Chinese physics research and education.

    Many people, not only at CERN but also throughout the world, were saddened to learn that their friend and colleague David Williams had passed away in the early hours of Tuesday 24 October. His death came after a year of fighting cancer with all of his usual determination and optimism. Even days before the end he was still welcoming to visitors, and was alert and interested in all their news. Born in 1944, David came to CERN from the University of Cambridge in 1966, with a degree in Physics and Computer Science. Joining what at the time was called the Documents and Data (DD) Division, in the earlier part his career he worked first on software for analysis of bubble chamber photographs, subsequently leading the group that supported experiments with 'hybrids' of bubble chambers and electronic detectors and then the group supporting online computing in experiments. He thus witnessed all of the enormous changes that took place in particle physics as the era of bubble chambers came to an end and the availability ...

  7. William Harvey, Aristotle and astrology.

    Science.gov (United States)

    Gregory, Andrew

    2014-06-01

    In this paper I argue that William Harvey believed in a form of astrology. It has long been known that Harvey employed a macrocosm-microcosm analogy and used alchemical terminology in describing how the two types of blood change into one another. This paper then seeks to examine a further aspect of Harvey in relation to the magical tradition. There is an important corollary to this line of thought, however. This is that while Harvey does have a belief in astrology, it is strongly related to Aristotle's views in this area and is quite restricted and attenuated relative to some contemporary beliefs in astrology. This suggests a more general thesis. While Harvey was amenable to ideas which we associate with the natural magic tradition, those ideas had a very broad range of formulation and there was a limit to how far he would accept them. This limit was largely determined by Harvey's adherence to Aristotle's natural philosophy and his Christian beliefs. I argue that this is also the case in relation to Harvey's use of the macrocosm-microcosm analogy and of alchemical terminology, and, as far as we can rely on the evidence, this informs his attitudes towards witches as well. Understanding Harvey's influences and motives here is important in placing him properly in the context of early seventeenth-century thought.

  8. William Paley's lost "intelligent design".

    2009-01-01

    William Paley's Natural Theology has experienced a resurgence in popularity in recent decades with the continuing controversies over the teaching of evolution and the emergence of a new "intelligent design" movement. But while both the movement's supporters and detractors agree that Paley is an intellectual forefather of the present-day movement, this agreement is forged at the expense of historical accuracy. Paley's intelligent design has almost nothing in common with the present day movement and, in fact, suggests theological arguments against the type of reasoning used by the modern movement. Paley wrote in reaction to Hume and in response to the evolutionary theories of Buffon and Erasmus Darwin. In this light, the Natural Theology suggests a different reading than it is usually given. Paley's narrowly-argued theology relies upon the ability to detect the presence of "purpose" in nature without relying upon knowing what those purposes are. His empirically-argued theology leads him to a God who operates through natural law, not in its contravention, and his concern goes far beyond proving the existence of a deity to undertaking the theological project of determining the attributes and characteristics of the deity. Though not himself an evolutionist, Paley put forth a theological worldview consistent with evolution. In fact, given his arguments that the observation of great contrivance increases the testimony of nature to God's power, Paley's philosophy might be more consistent with a theistic Darwinian evolution than with special creation.

  9. William Friedman, Geneticist Turned Cryptographer.

    William Friedman (1891-1969), trained as a plant geneticist at Cornell University, was employed at Riverbank Laboratories by the eccentric millionaire George Fabyan to work on wheat breeding. Friedman, however, soon became intrigued by and started working on a pet project of Fabyan's involving the conjecture that Francis Bacon, a polymath known for the study of ciphers, was the real author of Shakespeare's plays. Thus, beginning in ∼1916, Friedman turned his attention to the so called "Baconian cipher," and developed decryption techniques that bore similarity to approaches for solving problems in population genetics. His most significant, indeed pathbreaking, work used ideas from genetics and statistics, focusing on analysis of the frequencies of letters in language use. Although he had transitioned from being a geneticist to a cryptographer, his earlier work had resonance in his later pursuits. He soon began working directly for the United States government and produced solutions used to solve complex military ciphers, in particular to break the Japanese Purple code during World War II. Another important legacy of his work was the establishment of the Signal Intelligence Service and eventually the National Security Agency. Copyright © 2017 by the Genetics Society of America.

  14. The blot on the landscape: Fred Williams and Australian art history

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available A defining shift in Australian art historiography occurred with the publishing of Bernard Smith’s 1980 Boyer Lecture series, The Spectre of Truganini. Seeing the exclusion of an Aboriginal presence in Australian art through the ideas of Freud, the history of Australian art, Smith proposed, was a history of repression. After Smith, Ian McLean has developed the most detailed account of the history of Australian art according to this methodology. This essay examines the work of the modern Australian artist Fred Williams in relation to both Smith and McLean’s understanding of the history of Australian art but to expand on their work I argue that, rather than Freud alone, it is Lacan’s refiguring of Freud that offers us the most insight into Williams’s work. Further, insofar as I argue that the history of Australian art is the very subject matter of Williams’s work, his work stands in for a wider project, the understanding of the history of Australian art according to Lacan’s proposal of a foundational split between the eye and the gaze.

    2009-12-01

    Full Text Available Abstract Background Sepsis is an infection which has evoked a systemic inflammatory response. Clinically, the Systemic Inflammatory Response Syndrome (SIRS is identified by two or more symptoms including fever or hypothermia, tachycardia, tachypnoea and change in blood leucocyte count. The relationship between SIRS symptoms and morbidity and mortality in medical emergency ward patients is unknown. Methods We conducted a prospective cohort study of the frequency of SIRS and its relationship to sepsis and death among acutely hospitalised medical patients. In 437 consecutive patients, SIRS status, blood pressure, infection and comorbidity on admission was registered together with 28-day mortality. Results A hundred and fifty-four patients (35% had SIRS on admission, 211 patients (48% had no SIRS, and 72 patients (16% had insufficient data to evaluate their SIRS status. SIRS patients were 2.2 times more frequently infected, with 66/154 SIRS patients versus 41/211 non-SIRS patients: p Conclusion We found SIRS status on admission to be moderately associated with infection and strongly related to 28-day mortality.

    Viral marketing is a marketing strategy utilizes social media to spread information about a product or services provided. It is the most powerful way to share information in a short amount of time. The objective of this study is to investigate the dynamic of viral marketing within a time duration in the point of view of mathematics. This study used the epidemiological model known as Susceptible-Infected-Recovered (SIR). The model consists of a system of three differential equations with three state variables namely susceptible (S), infected (I) and recovered (R). It considers a case of SIR model with demography. Numerical experiments have been performed. The results show that viral marketing reaches its peak within two days. The online messages shared will become higher if the initial number of the infected individual has been increased.

    The SIR-B mapping experiment which will evaluate the utility of SAR images taken singularly, in pairs, and in combination with other data sets for cartographic, topographic, and thematic mapping, and determine the optimum configuration of a SAR system for future mapping mission is outlined. SIR-B is the first orbital imaging radar mission which will incorporate maintenance of geometric image fidelity along with careful calibration and documentation of internal timing and frequency parameters. This along and and the multiple incidence angle images of the same target which are necessary for stereoscopy and topographic mapping, make it the ideal opportunity for cartographic experimentation. It is emphasized that comprises a significant part of the overall experiment objectives.

    Canine babesiosis is a tick-borne disease caused by the haemoprotozoan parasites of the genus Babesia. Early detection of systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) is of major importance in clinical practice for providing information about severity and outcomes of the disease and therapy. Plasma samples were taken at admission from five dogs with uncomplicated babesiosis caused by B. canis canis, five dogs with babesiosis and SIRS, five dogs with babesiosis and MODS, and five healthy dogs. After two-dimensional electrophoresis and capillary reversed - phase liquid chromatography coupled online with tandem mass spectrometry, 68 differentially expressed spots with level of significance PSIRS in babesiosis was characterised by increases in paraoxonase 1 and apoA-I, whereas MODS with decrease of complement inhibitors leading to prolonged complement activation and decrease of vitamin D binding protein due to haemolysis and activation of the coagulation cascade.

    2014-05-01

    Consensus guidelines recommend sepsis screening for adults with systemic inflammatory response syndrome (SIRS), but the epidemiology of SIRS among adult emergency department (ED) patients is poorly understood. Recent emphasis on cost-effective, outcomes-based healthcare prompts the evaluation of the performance of large-scale efforts such as sepsis screening. We studied a nationally representative sample to clarify the epidemiology of SIRS in the ED and subsequent category of illness. This was a retrospective analysis of ED visits by adults from 2007 to 2010 in the National Hospital Ambulatory Medical Care Survey (NHAMCS). We estimated the incidence of SIRS using initial ED vital signs and a Bayesian construct to estimate white blood cell count based on test ordering. We report estimates with Bayesian modified credible intervals (mCIs). We used 103,701 raw patient encounters in NHAMCS to estimate 372,844,465 ED visits over the 4-year period. The moderate estimate of SIRS in the ED was 17.8% (95% mCI: 9.7 to 26%). This yields a national moderate estimate of approximately 16.6 million adult ED visits with SIRS per year. Adults with and without SIRS had similar demographic characteristics, but those with SIRS were more likely to be categorized as emergent in triage (17.7% versus 9.9%, pSIRS patients. Traumatic causes of SIRS comprised 10% of presentations; other traditional categories of SIRS were rare. SIRS is very common in the ED. Infectious etiologies make up only a quarter of adult SIRS cases. SIRS may be more useful if modified by clinician judgment when used as a screening test in the rapid identification and assessment of patients with the potential for sepsis.

    In this paper, a time-delayed SIR model with a nonlinear incidence rate is considered. The existence of Hopf bifurcations at the endemic equilibrium is established by analyzing the distribution of the characteristic values. A explicit algorithm for determining the direction of the Hopf bifurcation and the stability of the bifurcating periodic solutions are derived by using the normal form and the center manifold theory. Numerical simulations to support the analytical conclusions are carried out

    In order to maximize the benefit of prompt antimicrobial therapy and avoid the risk associated with inappropriate use of antimicrobial agents, patients with suspected sepsis must be rapidly differentiated from patients with systemic inflammatory response syndrome (SIRS). In combination with standard microbiological testing, a number of biomarkers have been recently evaluated for this purpose, and the performance characteristics of the most promising of these are reviewed.

    The College Fjord with its glaciers was imaged by ASTER on June 24, 2000.This image covers an area 20 kilometers (13 miles) wide and 24 kilometers (15 miles) long in three bands of the reflected visible and infrared wavelength region. College Fjord is located in Prince Williams Sound, east of Seward, Alaska. Vegetation is in red, and snow and ice are white and blue. Ice bergs calved off of the glaciers can be seen as white dots in the water. At the head of the fjord, Harvard Glacier (left) is one of the few advancing glaciers in the area; dark streaks on the glacier are medial moraines: rock and dirt that indicate the incorporated margins of merging glaciers. Yale Glacier to the right is retreating, exposing (now vegetated) bedrock where once there was ice. On the west edge of the fjord, several small glaciers enter the water. This fjord is a favorite stop for cruise ships plying Alaska's inland passage.This image is located at 61.2 degrees north latitude and 147.7 degrees west longitude. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager.

    Full Text Available Abstract Introduction: The world renowned comedian and four-time Oscar nominated actor Robin Williams died on August 11, 2014. From the outset, the news indicated that his death was believed to be a suicide and this was later confirmed to be true by the autopsy reports. Williams had been suffering from severe depression, which is believed to be the leading contributor to his suicide. In this case study, I will highlight the event of the actor's suicide and the main risk factors along with depression leading to his tragic death. As of the end of 2015, no other case study seemed to have addressed or explored the links between the cause (or causes and events leading to Robin Williams' suicide. Case description: Robin Williams was suffering from relationship problems, financial problems, drug addiction, and major depression. All of these factors led to his suicide. Comments: The chances of committing suicide drastically increase in the presence of any of the key risk factors. Unfortunately, the actor Robin Williams was dealing with four of the major risk factors all together, which put him at a high risk of committing suicide and eventually led to his tragic death.

    2010-01-01

    Recent advances in social cognitive neuroscience have led to the concept of the ''social brain''. The social brain includes neural processes specialized for processing social information necessary for the recognition of self and others, and interpersonal relationships. Because of its unique behavioral phenotypic features which includes 'hypersociability', Williams syndrome has gained popularity among social cognitive neuroscientists. Individuals with Williams syndrome share the same genetic risk factor for cognitive-behavioral dysfunction utilizing brain imaging to elucidate endophenotype provides us with an unprecendented opportunity to study gene, brain and behavior relationships especially those related to social cognition. In this review, we provide an overview of neuroimaging studies on social cognition in Williams syndrome and discuss the neural basis of the social brain. (author)

    In accordance with the 1st International pediatric sepsis consensus conference, where sepsis was defined as SIRS associated with suspected or proven infection, we have identified the need to assess the prevalence of SIRS and sepsis in children with abnormal temperatures hospitalized in The Children's Clinical University Hospital in Latvia. A descriptive prospective point prevalence study (using two time periods, each 24 h, randomly chosen) was conducted on all children (n = 943) treated in the hospital. All children with abnormal temperatures - fever or hypothermia (n = 92) - were included in the study. Questionnaires evaluating age-specific SIRS criteria were completed. The prevalence of SIRS was detected with 95% CI. Out of a total of 943 patients treated in the hospital, 10% (n = 92) had abnormal temperatures. In all these cases the abnormal temperature was a fever; hypothermia was not established in any patient. Of the children with fever, 72% (n = 66) had SIRS. Of the SIRS patients, 8% (n = 5) developed sepsis, 5% (n = 3) severe sepsis and 2% (n = 1) septic shock. Seventy-six percent (n = 50) of the SIRS patients had fever in combination with respiratory rate >2 SD above normal for age; 50% (n = 33) had fever with abnormal leukocyte count; 15% (n = 10) had fever with tachycardia >2 SD above normal for age. Most of the SIRS patients (39%, n = 25) were aged 2-5 years. Twenty-one percent (n = 14) of the children with SIRS and 50% (n = 2) of those with severe sepsis and septic shock had an underlying disease. In no case was SIRS and sepsis recognized by doctors and the diagnoses were not recorded on the patients' cards. Our results would indicate a high risk for sepsis development in children with SIRS. Early SIRS diagnosis and awareness of risk of developing sepsis could change the medical approach to the patient in everyday clinical practice, eventually leading to early, goal-directed therapy for sepsis.

    With the prevalence of new media, e.g., microblogging, rumors spread faster and wider than ever before. On the basis of prior studies, this paper modifies a flow chart of the rumor spreading process with the SIR (Susceptible, Infected, and Recovered) model, and thus makes the rumor spreading process more realistic and apparent. The authors believe that ignorants will inevitably change their status once they are made aware of a rumor by spreaders; the probabilities that a spreader becomes a stifler are differentiated in accordance with reality. In the numerical simulation part, the impact that variations of different parameters have on the rumor spreading process will be analyzed.

    To investigate whether systemic inflammatory response syndrome (SIRS) after cerebral infarction is associated with poor outcome and its associated clinical factors. We prospectively studied 500 patients with cerebral infarction, recorded the associated clinical factors on presentation and calculated the mortality at 21st day. There are 85 SIRS patients in 500 patients with cerebral infarction, 31 with total anterior cerebral infarction (TACI), 34 with partial anterior cerebral infarction (PACI), 15 with posterior cerebral infarction (POCI) and 5 with lacunar cerebral infarction (LACI). The frequency of SIRS was positively correlated with mortality rate according to Oxfordshire Community Stroke Project (OCSP) subtypes in cerebral infarction patients with fever (Spearman correlation coefficient = 1.0; P SIRS and mortality of cerebral infarction were as follows: age, infection, 48 h Chinese Stroke Scale score, 48 h Glasgow score, OCSP subtypes and dysphagia. Diabetes was the risk factor for SIRS, but had no effect on mortality. On Cox regression, 48 h Glasgow score was the sole independent risk factor of outcome. However, if SIRS was included in the formula, P > 0.05. SIRS is the predictor of poor outcome after acute cerebral infarction. It is important to prevent SIRS especially in TACI and POCI. Diabetes is the risk factor for SIRS, but has no effect on mortality.

    The clinical entity, definitions, and the significance of SIRS (systemic inflammatory response syndrome) were reviewed. The term, SIRS was proposed to define sepsis and its sequelae clearly in 1991, in order to make early detection of the disease possible, and to improve the ability to compare innovative potential diagnostic and therapeutic modalities by standardizing terms. Although the criteria of SIRS is not strict and too sensitive, SIRS has been shown to be useful as a warning sign of severe condition in clinical setting. We also discussed about a new concept, CARS (compensatory anti-inflammatory response syndrome), which was characterized as anti-inflammatory mediators-dominant condition, in this issue.

    2007-02-01

    Ingested type I IFN inhibits clinical attacks, relapses and inflammation in murine chronic relapsing EAE by inhibiting Th1-like cytokines. Type I IFN activates human suppressor T cells that produce SIRS. We examined whether oral (ingested) SIRS peptide inhibits EAE by decreasing Th1-like cytokines. Parenteral SIRS peptide 1-21 showed a significant inhibition of disease severity in murine EAE. Ingested SIRS peptide at 10 and 100 microg SIRS peptide showed a significant inhibition of disease severity but also a prolonged delay in the onset of disease compared to placebo. There were significantly less inflammatory foci in the SIRS peptide fed group compared to the control mock fed group. Splenocytes from SIRS peptide 1-21 fed mice showed increased production of Th2-like CD30L, IL-13, TCA-3 cytokines/chemokines and decreased production of Th1-like cytokine lymphotactin. Ingested (oral) SIRS peptide significantly inhibits both clinical EAE and inflammation predominately via counter-regulatory type 2-like cytokines/chemokines IL-13, CD30L and TCA-3.

    The interval from presentation with systemic inflammatory response syndrome (SIRS) to the start of antibiotic administration affects mortality in patients with sepsis. However, patients with subarachnoid hemorrhage (SAH) often develop SIRS directly from their brain injury, making it a less useful indicator of infection. We therefore hypothesized that SIRS would not be a suitable trigger for antibiotics in this population. We examined the time from the development of SIRS until antibiotic initiation and its relationship to long-term neurological outcomes in patients with nontraumatic SAH. Patients' baseline characteristics, time of antibiotic administration, and hospital course were collected from retrospective chart review. The primary outcome, 6-month functional status, was prospectively determined using blinded, structured interviews incorporating the modified Rankin Scale (mRS). Sixty-six of 70 patients with SAH during the study period had 6-month follow-up and were included in this analysis. SIRS developed in 57 patients (86%, 95% CI 78-95%). In ordinal logistic regression models controlling for age and illness severity, the time from SIRS onset until antibiotic initiation was not associated with 6-month mRS scores (OR per hour, 0.994; 95% CI 0.987-1.001). In this cohort of patients with SAH, time from SIRS onset until antibiotic administration was not related to functional outcomes. Our results indicate that SIRS is nonspecific in patients with SAH, and support the safety of withholding antibiotics in those who lack additional evidence of infection or hemodynamic deterioration.

    2016-06-20

    Systemic inflammation in humans may be triggered by infection, termed sepsis, or non-infective processes, termed non-infective systemic inflammatory response syndrome (SIRS). MicroRNAs regulate cellular processes including inflammation and may be detected in blood. We aimed to establish definitive proof-of-principle that circulating microRNAs are differentially affected during sepsis and non-infective SIRS. Critically ill patients with severe (n = 21) or non-severe (n = 8) intra-abdominal sepsis; severe (n = 23) or non-severe (n = 21) non-infective SIRS; or no SIRS (n = 16) were studied. Next-generation sequencing and qRT-PCR were used to measure plasma microRNAs. Detectable blood miRNAs (n = 116) were generally up-regulated in SIRS compared to no-SIRS patients. Levels of these 'circulating inflammation-related microRNAs' (CIR-miRNAs) were 2.64 (IQR: 2.10-3.29) and 1.52 (IQR: 1.15-1.92) fold higher for non-infective SIRS and sepsis respectively (p SIRS. Six CIR-miRNAs (miR-30d-5p, miR-30a-5p, miR-192-5p, miR-26a-5p, miR-23a-5p, miR-191-5p) provided good-to-excellent discrimination of severe sepsis from severe SIRS (0.742-0.917 AUC of ROC curves). CIR-miRNA levels inversely correlated with pro-inflammatory cytokines (IL-1, IL-6 and others). Thus, among critically ill patients, sepsis and non-infective SIRS are associated with substantial, differential changes in CIR-miRNAs. CIR-miRNAs may be regulators of inflammation and warrant thorough evaluation as diagnostic and therapeutic targets.

    Clinical disorders have intrigued the human mind for thousands of years. Many are enshrined in history as 'medical curiosities'. This report is a tribute to one of the greatest minds of modern genetics and medicine, Sir Archibald Edward Garrod (1857--1936), who brought forward the scientific study of inborn errors of metabolism. Garrod's concept of 'chemical individuality' with no awareness of 'genes' more than 100 years ago is an amazing example of futuristic thinking. His own words reflect this, 'Owing, as I believe, to their chemical individuality different human beings differ widely in their liability to individual maladies, and to some extent in the signs and symptoms which they exhibit'. The concept of chemical individuality is here to stay. Garrod has also provided insight into a number of scientific concepts and modern thinking.

    It remains difficult to treat severely ill patients, especially those who have sepsis and subsequent multiple organ dysfunction syndrome. We propose the hypothesis that the pathophysiology in the sequential sepsis and multiple organ dysfunction syndrome may be strongly related to the imbalance between inflammatory cytokines and antiinflammatory cytokines induced for the host defense to active neutrophils and endothelial cells. Thus we attempted to develop cytokine modulation therapy to normalize the cytokine balance in the host defense system. In this review, we elucidate the relationship between cytokine imbalance and SIRS/CARS in patients with severe burn injury. Furthermore, we examine the possible usage of G-CSF to amplify neutrophil function, and clarify the reasons why various innovative therapies against sepsis have failed.

The scattering parameters of the structure are measured using vector network analyzer (VNA. The self generated capacitive and inductive reactances within the interdigital resonators exhibited in a resonance frequency of 4.9 GHz. The resonant frequency and bandwidth of the capacitive cross-coupled resonator is directly optimized from the physical arrangement of the resonators. The measured insertion loss (S21 and return loss (S11 were 0.3 dB and 28 dB, respectively, at resonance frequency which were almost close to the simulation results.

This paper traces his lecturing career from its beginnings in Ireland to the triumphs of the Royal Institution, and on lecture tours in the United States of America. After a period in mathematics and mechanics, he became a populariser of science, especially astronomy, and found fame and fortune among the working classes and the aristocracy. What motivated him to tireless travels is uncertain, but it might have been that it was rewarding, financially and to his reputation. Whatever his motives, contemporary accounts are clear that BallÕs lectures were extremely popular and well-received.

  19. SIR (Safe Integral Reactor) - reducing size can reduce cost

    International Nuclear Information System (INIS)

    Hayns, M.R.

    1991-01-01

    Traditional engineering economics have favoured the advantages of larger size as a means of reducing specific capital costs and hence unit generating costs. For large and small plants utilising the same concept, e.g. a small four-loop PWR vs a large four-loop PWR with the same number of components, economies of scale are well established. If, however, a smaller plant is sized to take advantage of features which are only feasible at smaller outputs, is of simpler design, with the advantage taken of the simplified design to produce the most cost-effective layout, and incorporates fewer, more easily replaceable components with minimal assembly on site, it is possible to produce a plant which is competitive with larger plant of more traditional design. When 'system' effects, such as better matching of installed capacity to the growth in demand and the fact that a smaller total capacity will be needed to meet a given demand with a specified level of confidence, are taken into account, it can be shown that a utility's overall cash-flow position can be improved with lower associated absolute financial risks. The UK/US Safe Integral Reactor (SIR) is an integral pressurized water reactor in the 300-400 MW(e) range which utilises conventional water reactor technology in a way not feasible at the very large, sizes of recent years. The SIR concept is briefly explained and its technical and economic advantages in terms of simplicity, construction, maintenance, availability, decommissioning, safety and siting described. The results of system analyses which demonstrate the overall financial advantages to a utility are presented. (author)

  20. Rorty, Williams, and Davidson: Skepticism and Metaepistemology

    Full Text Available We revisit an important exchange on the problem of radical skepticism between Richard Rorty and Michael Williams. In his contribution to this exchange, Rorty defended the kind of transcendental approach to radical skepticism that is offered by Donald Davidson, in contrast to Williams’s Wittgenstein-inspired view. It is argued that the key to evaluating this debate is to understand the particular conception of the radical skeptical problem that is offered in influential work by Barry Stroud, a conception of the skeptical problem which generates metaepistemological ramifications for anti-skeptical theories. In particular, we argue that, contra Williams, Rorty’s view that Davidson was offering a theoretical diagnosis of radical skepticism can be consistently maintained with his transcendental approach.

    Ultraviolet light (UV) causes DNA damage that is removed by nucleotide excision repair (NER). UV-induced DNA lesions must be recognized and repaired in nucleosomal DNA, higher order structures of chromatin and within different nuclear sub-compartments. Telomeric DNA is made of short tandem repeats located at the ends of chromosomes and their maintenance is critical to prevent genome instability. In Saccharomyces cerevisiae the chromatin structure of natural telomeres is distinctive and contingent to telomeric DNA sequences. Namely, nucleosomes and Sir proteins form the heterochromatin like structure of X-type telomeres, whereas a more open conformation is present at Y'-type telomeres. It is proposed that there are no nucleosomes on the most distal telomeric repeat DNA, which is bound by a complex of proteins and folded into higher order structure. How these structures affect NER is poorly understood. Our data indicate that the X-type, but not the Y'-type, sub-telomeric chromatin modulates NER, a consequence of Sir protein-dependent nucleosome stability. The telomere terminal complex also prevents NER, however, this effect is largely dependent on the yKu-Sir4 interaction, but Sir2 and Sir3 independent. © The Author(s) 2017.

  5. Fighting addiction's death row: British Columbia Supreme Court Justice Ian Pitfield shows a measure of legal courage

    Full Text Available Abstract The art in law, like medicine, is in its humanity. Nowhere is the humanity in law more poignant than in BC Supreme Court Justice Ian Pitfield's recent judgment in the legal case aimed at protecting North America's only supervised injection facility (SIF as a healthcare program: PHS Community Services Society versus the Attorney General of Canada. In order to protect the SIF from politicization, the PHS Community Services Society, the community organization that established and operates the program, along with two people living with addiction and three lawyers working for free, pro bono publico, took the federal government of Canada to court. The courtroom struggle that ensued was akin to a battle between David and Goliath. The judge in the case, Justice Pitfield, ruled in favour of the PHS and gave the Government of Canada one year to bring the Controlled Drugs and Substances Act (CDSA into compliance with the country's Charter of Rights and Freedoms. If parliament fails to do so, then the CDSA will evaporate from enforceability and law in June of 2009. Despite the fact that there are roughly twelve million intravenous drug addiction users in the world today, politics andprejudice oards harm reduction are still a barrier to the widespread application of the "best medicine" available for serious addicts. Nowhere is this clearer than in the opposition by conservative Prime Minister Stephen Harper and his faithful servant, federal health minister Tony Clement, towards Vancouver's SIF ("Insite". The continued angry politicization of addiction will only lead to the tragic loss of life, as addicts are condemned to death from infectious diseases (HIV & hepatitis and preventable overdoses. In light of the established facts in science, medicine and now law, political opposition to life-saving population health programs (including SIFs to address the effects of addiction is a kind of implicit capital punishment for the addicted.

    Enterobacteriaceae clinical isolates showing amikacin resistance (MIC 64 to >256 mg/L) in the absence of 16S rRNA methyltransferase (MTase) genes were found. The aim of this study was to clarify the molecular mechanisms underlying amikacin resistance in Enterobacteriaceae clinical isolates that do not produce 16S rRNA MTases. PCR was performed to detect already-known amikacin resistance determinants. Cloning experiments and sequence analyses were performed to characterize unknown amikacin resistance determinants. Transfer of amikacin resistance determinants was performed by conjugation and transformation. The complete nucleotide sequence of the plasmids was determined by next-generation sequencing technology. Amikacin resistance enzymes were purified with a column chromatography system. The enzymatic function of the purified protein was investigated by thin-layer chromatography (TLC) and HPLC. Among the 14 isolates, 9 were found to carry already-known amikacin resistance determinants such as aac(6')-Ia and aac(6')-Ib. Genetic analyses revealed the presence of a new amikacin acetyltransferase gene, named aac(6')-Ian, located on a 169 829 bp transferable plasmid (p11663) of the Serratia marcescens strain NUBL-11663, one of the five strains negative for known aac(6') genes by PCR. Plasmid p11663 also carried a novel ESBL gene, named blaTLA-3. HPLC and TLC analyses demonstrated that AAC(6')-Ian catalysed the transfer of an acetyl group from acetyl coenzyme A onto an amine at the 6'-position of various aminoglycosides. We identified aac(6')-Ian as a novel amikacin resistance determinant together with a new ESBL gene, blaTLA-3, on a transferable plasmid of a S. marcescens clinical isolate. © The Author 2015.

  7. Nicotinamide clearance by Pnc1 directly regulates Sir2-mediated silencing and longevity.

    Science.gov (United States)

    Gallo, Christopher M; Smith, Daniel L; Smith, Jeffrey S

    2004-02-01

    The Saccharomyces cerevisiae Sir2 protein is an NAD(+)-dependent histone deacetylase (HDAC) that functions in transcriptional silencing and longevity. The NAD(+) salvage pathway protein, Npt1, regulates Sir2-mediated processes by maintaining a sufficiently high intracellular NAD(+) concentration. However, another NAD(+) salvage pathway component, Pnc1, modulates silencing independently of the NAD(+) concentration. Nicotinamide (NAM) is a by-product of the Sir2 deacetylase reaction and is a natural Sir2 inhibitor. Pnc1 is a nicotinamidase that converts NAM to nicotinic acid. Here we show that recombinant Pnc1 stimulates Sir2 HDAC activity in vitro by preventing the accumulation of NAM produced by Sir2. In vivo, telomeric, rDNA, and HM silencing are differentially sensitive to inhibition by NAM. Furthermore, PNC1 overexpression suppresses the inhibitory effect of exogenously added NAM on silencing, life span, and Hst1-mediated transcriptional repression. Finally, we show that stress suppresses the inhibitory effect of NAM through the induction of PNC1 expression. Pnc1, therefore, positively regulates Sir2-mediated silencing and longevity by preventing the accumulation of intracellular NAM during times of stress.

    Systemic inflammatory response syndrome (SIRS) is a common complication after cardiovascular surgery that in severe cases can lead to multiple organ dysfunction syndrome and even death. We therefore set out to identify reliable early biomarkers for SIRS in a prospective small patient study for timely intervention. 21 Patients scheduled for planned cardiovascular surgery were recruited in the study, monitored for signs of SIRS and blood samples were taken to investigate biomarkers at pre-assigned time points: day of admission, start of surgery, end of surgery, days 1, 2, 3, 5 and 8 post surgery. Stored plasma and cryopreserved blood samples were analyzed for cytokine expression (IL1β, IL2, IL6, IL8, IL10, TNFα, IFNγ), other pro-inflammatory markers (sCD163, sTREM-1, ESM-1) and response to endotoxin. Acute phase proteins CRP, PCT and pro-inflammatory cytokines IL6 and IL8 were significantly increased (pSIRS group at the end of surgery. Soluble TREM-1 plasma concentrations were significantly increased in patients with SIRS (pSIRS after cardiovascular surgery. A combination of normalized IL1β plasma levels, responses to endotoxin and soluble TREM-1 plasma concentrations at the end of surgery are predictive markers of SIRS development in this small scale study and could act as an indicator for starting early therapeutic interventions.

    Little is known regarding systemic inflammatory response syndrome (SIRS) criteria and mortality in developing countries. We evaluated the utility of the SIRS criteria to predict death among a paediatric surgical population in Lilongwe, Malawi. Age, SIRS variables (temperature, heart rate, systolic blood pressure, respiratory rate and leucocyte count), diagnosis, surgical procedure and outcome were analysed for paediatric surgical patients during 2012. Age-specific criteria for SIRS variables were then applied to the data. Using published SIRS criteria, temperature was the only variable that correlated with mortality. When norms for an African population were used, leucocyte count also correlated with mortality. With the exception of temperature, published SIRS criteria were not predictive of mortality. Leucocyte count became predictive of death using norms specific to an African population. SIRS and its component data are a worthwhile area of future prospective research in developing countries. © The Author [2014]. Published by Oxford University Press. All rights reserved.

    Triggering receptor expressed on myeloid cells-1 (TREM-1) was reported to play a key roll in amplification of production of inflammatory cytokines. TREM-1 is suggested to be a specific biomarker for sepsis for this reason, but the clinical significance of TREM-1 has not been elucidated. We investigated TREM-1 expression on the cell-surface, and plasma levels of soluble TREM-1 (sTREM-1) in patients with non-infectious systemic inflammatory response syndrome (SIRS) and sepsis admitted to the ICU. Thirty-five patients with SIRS and 21 patients with sepsis admitted to ICU were subjected to the study. TREM-1 expressions on the surfaces of monocytes and neutrophils were measured by flow cytometry. Plasma sTREM-1 level and serum interleukin (IL)-6 level were measured. Septic patients had decreased TREM-1 expression, clearly on neutrophils or to a lesser extent on monocyte compared to SIRS patients on ICU admission (neutrophils pSIRS patients (pSIRS/sepsis patients (pSIRS patients. sTREM-1 may be useful to evaluate disease severity and outcome of patients with SIRS or sepsis.

    2016-12-01

    Full Text Available After the Syrian civil war, deaths of those fleeing crisis areas have tragically become a regular news item. Not new to the world, however, such crises emerge from tensions between identity and difference as codified in international politics, whereby refugees and migrants become the Other and subject to unyielding universals, such as the law or narrow concepts of what is right. Indeed, the cultural logic of “global identities” informing the current refugee and migrant crisis seems recurrent, as exemplified in the recent cases of the Tamils from Sri Lanka and the Somalis. The cultural logic of global identity is also reflected in the popular nineteenth-century novella by Sir Arthur Conan Doyle, The Man with the Twisted Lip, in which the main character disguises himself as a professional beggar to appeal to middle class values in order to incite their guilty consciences. Drawing on Ian Baucom, Marc Shell, and Jean-Joseph Goux, this article argues that the main character’s actions reflect and embody the cultural logic of the global politico-economy in late nineteenth century London. As such, Doyle’s novella illustrates the Derridean notion of hospitality by revealing that “identity and difference are mutually constitutive” (Baker 109 and offers insightful commentary on the current refugee and migrant crisis.

    William Hazlitt, a distinguished literary figure of the early nineteenth century and a forerunner of psychoanalytic insights, had a keen awareness of the impact of the imagination on assessing works of art. At forty-two, he became hopelessly involved in an obsessive love affair with a nineteen-year-old woman and could not extricate himself from the relationship. The affair followed the death of his father, a powerful influence on his life. Factors in his obsessive love included finding an object of idealization subject to his imaginative creation and narcissistically reexperiencing himself about to begin a new life. © 2017 The Psychoanalytic Quarterly, Inc.

    Full Text Available Joint fluid aspiration, or arthrocentesis, is one of the most useful and commonly performed procedures for the diagnosis and treatment of rheumatic diseases, but to date no definite guidelines have been published. For this reason, a group of experts of the Italian Society of Rheumatology (SIR produced evidence based recommendations for performing arthrocentesis. Among them, the most relevant are: a arthrocentesis is necessary when synovial effusion of unknown origin is present, especially if septic or crystal arthritis is suspected; b the patient should be clearly informed of the benefits and risks of the procedure in order to give an informed consent; c ultrasonography should be used to facilitate arthrocentesis in difficult joints; d fluid evacuation often has a therapeutic effect and facilitates the success of the following intraarticular injection; e careful skin disinfection and the use of sterile, disposable material is mandatory for avoiding septic complications. Disposable, non sterile gloves should always be used by the operator, mainly for his own protection; f contraindications are the presence of skin lesions or infections in the area of the puncture; g the patient’s anticoagulant treatment is not a contraindication, providing the therapeutic range is not exceeded; h joint rest after arthrocentesis is not indicated. Several of these recommendations were based on experts’ opinion rather than on published evidence which is scanty.

  17. Sir James Young Simpson and religion: myths and controversies.

    Science.gov (United States)

    Cameron, Ewen A; MacGillivray, Neil

    2013-02-01

    This paper analyses two key aspects of the life and work of Sir James Young Simpson: his evangelical Christianity and his reaction to criticism following his use of anaesthesia in obstetrics. Simpson's personal religious struggle is placed in the context of the devastating events surrounding the Disruption of the established Church of Scotland in 1843. Whatever his involvement in the events of that year, the development of his faith demonstrates his simple evangelical conviction in the atonement of Christ, very much in keeping with that of many believers in Victorian Britain. There has arisen the notion (still current as is clear from publications in medical journals within recent years) that there was a savage religious response, especially in Presbyterian Scotland, to his use of chloroform - in reality the attack on Simpson's enthusiastic promotion of chloroform was brief, sporadic and of little moment. Simpson's carefully constructed counter to criticism of anaesthesia, drawing on considerable theological and linguistic expertise, reveals a complexity at odds with the simplicity of his faith. The contrast is so great and the reaction so elaborate that it is proposed that Simpson deliberately exaggerated the affair, believing the publicity could only be valuable.

    2015-07-01

    Recent studies of rumor or information diffusion process in complex networks show that in contrast to traditional comprehension, individuals who participate in rumor spreading within one network do not always get the rumor from their neighbors. They can obtain the rumor from different sources like online social networks and then publish it on their personal sites. In our paper, we discuss this phenomenon in complex networks by adopting the concept of independent spreaders. Rather than getting the rumor from neighbors, independent spreaders learn it from other channels. We further develop the classic "ignorant-spreaders-stiflers" or SIR model of rumor diffusion process in complex networks. A steady-state analysis is conducted to investigate the final spectrum of the rumor spreading under various spreading rate, stifling rate, density of independent spreaders and average degree of the network. Results show that independent spreaders effectively enhance the rumor diffusion process, by delivering the rumor to regions far away from the current rumor infected regions. And though the rumor spreading process in SF networks is faster than that in ER networks, the final size of rumor spreading in ER networks is larger than that in SF networks.

    Resveratrol (RES) has been studied for its effects on the lifespan extension of Caenorhabditis elegans, but controversy still remains on its mechanism related with SIR-2. In this study, longevity assay was performed to confirm SIR-2-dependent lifespan extension of C. elgeans with RES and oxyresveratrol (OXY), an isomer of hydroxylated RES using loss-of-function mutants of C. elegans including sir-2.1 mutant. The results showed that OXY and RES significantly (P elegans compared with the control. OXY and RES also significantly (P elegans by overexpression of SIR-2.1, which is related to lifespan extension through calorie restriction and the AMP-activated protein kinase (AMPK) pathway, although this process is independent of the FOXO/DAF-16 pathway. © 2016 by the Society for Experimental Biology and Medicine.

    The Structured Interview of Reported Symptoms (SIRS; Rogers et al., Structured interview of reported symptoms (SIRS) and professional manual, 1992) is a well-validated psychological measure for the assessment of feigned mental disorders (FMD) in clinical, forensic, and correctional settings. Comparatively little work has evaluated its usefulness in compensation and disability contexts. The present study examined SIRS data from 569 individuals undergoing forensic neuropsychiatric examinations for the purposes of workers' compensation, personal injury, or disability proceedings. Using bootstrapping comparisons, three primary groups were identified: FMD, feigned cognitive impairment (FCI), genuine-both (GEN-Both) that encompasses both genuine disorders (GEN-D) and genuine-cognitive presentation (GEN-C). Consistent with the SIRS main objective, very large effect sizes (M Cohen's d = 1.94) were observed between FMD and GEN-Both groups. Although not intended for this purpose, moderate to large effect sizes (M d = 1.13) were found between FCI and GEN-Both groups. An important consideration is whether SIRS results are unduly affected by common diagnoses or clinical conditions. Systematic comparisons were performed based on common disorders (major depressive disorder, PTSD, and other anxiety disorders), presence of a cognitive disorder (dementia, amnestic disorder, or cognitive disorder NOS), or intellectual deficits (FSIQ SIRS primary scales was small and nonsignificant, providing evidence of the SIRS generalizability across these diagnostic categories. Finally, the usefulness of the SIRS improbable failure-revised (IF-R) scale was tested as a FCI screen. Although it has potential in ruling out genuine cases, the IF-R should not be used as a feigning screen.

    Coagulopathy and thrombocytopenia often occur in critically ill patients, and disseminated intravascular coagulation (DIC) can lead to multiple organ dysfunction and a poor outcome. However, the relation between coagulopathy and systemic inflammatory response has not been thoroughly clarified. Thus, we evaluated coagulative activity, organ dysfunction, and systemic inflammatory response syndrome (SIRS) in critically ill patients with thrombocytopenia and examined the balance between coagulopathy and systemic inflammation. Two hundred seventy-three patients, who were admitted to 13 critical care centers in Japan and fulfilled the criteria of platelet count of less than 150*10(9)/L, were included. Coagulative variables (platelet count, fibrin/fibrinogen degradation products, and DIC scores), organ dysfunction index (Sequential Organ Failure Assessment [SOFA] score), and SIRS score in each patient were evaluated for 4 consecutive days after fulfilling the above entry criteria. The effect of SIRS on coagulopathy and organ dysfunction was evaluated in these patients. Both the maximum SIRS score and entry SIRS score had significant relation to the maximum SOFA score during the observation period. Coagulation disorders indicated by the minimum platelet count, maximum DIC scores, and positivity for DIC worsened gradually with increases in SIRS scores. Both the minimum platelet count and maximum DIC scores were significantly correlated with the maximum SOFA score, indicating that a relation exists between coagulopathy and organ dysfunction. In critically ill patients with thrombocytopenia, coagulopathy and organ dysfunction progress with significant mutual correlation, depending on the increase in SIRS scores. The SIRS-associated coagulopathy may play a critical role in inducing organ dysfunction after severe insult.

    The European SMART-1 mission to the Moon, primarily a testbed for innovative technologies, was launched in September 2003 and will reach the Moon in 2005. On board are several scientific instruments, including the point-spectrometer SMART-1 Infrared Spectrometer (SIR). Taking into account the capabilities of the SMART-1 mission and the SIR instrument in particular, as well as the open questions in lunar science, a selection of targets for SIR observations has been compiled. SIR can address at least five topics: (1) Surface/regolith processes; (2) Lunar volcanism; (3) Lunar crust structure; (4) Search for spectral signatures of ices at the lunar poles; and (5) Ground truth and study of geometric effects on the spectral shape. For each topic we will discuss specific observation modes, necessary to achieve our scientific goals. The majority of SIR targets will be observed in the nadir-tracking mode. More than 100 targets, which require off-nadir pointing and off-nadir tracking, are planned. It is expected that results of SIR observations will significantly increase our understanding of the Moon. Since the exact arrival date and the orbital parameters of the SMART-1 spacecraft are not known yet, a more detailed planning of the scientific observations will follow in the near future.

    Adenosine (ADO) is an endogenous nucleoside, which has been involved in blood pressure failure during severe systemic inflammatory response syndrome (severe SIRS) after cardiac surgery with cardiopulmonary bypass (CPB). Adenosine acts via its receptor subtypes, namely A1, A2A, A2B, or A3. Because A2A receptors are implicated in vascular tone, their expression might contribute to severe SIRS. We compared adenosine plasma levels (APLs) and A2A ADO receptor expression (ie, B, K, and mRNA amount) in patients with or without postoperative SIRS. : This was a prospective comparative observational study. Forty-four patients who underwent cardiac surgery involving CPB. Ten healthy subjects served as controls. Among the patients, 11 presented operative vasoplegia and postoperative SIRS (named complicated patients) and 33 were without vasoplegia or SIRS (named uncomplicated patients). Adenosine plasma levels, K, B, and mRNA amount (mean +/- SD) were measured on peripheral blood mononuclear cells. Adenosine plasma levels, B, and K were significantly higher in complicated patients than in uncomplicated patients (APLs: 2.7 +/- 1.0 vs 1.0 +/- 0.5 micromol l, P SIRS after CPB.

    Systemic inflammatory response syndrome (SIRS) is frequently observed after extracorporeal membrane oxygenation (ECMO) decannulation; however, these issues have not been investigated well in the past. Retrospective chart review was performed to identify post-ECMO SIRS phenomenon, defined by exhibiting 2/3 of the following criteria: fever, leukocytosis, and escalation of vasopressors. The patients were divided into 2 groups: patients with documented infections (Group I) and patients with true SIRS (Group TS) without any evidence of infection. Survival and pre-, intra- and post-ECMO risk factors were analyzed. Among 62 ECMO survivors, 37 (60%) patients developed the post-ECMO SIRS phenomenon, including Group I (n = 22) and Group TS (n = 15). The 30-day survival rate of Group I and TS was 77% and 100%, respectively (p = 0.047), although risk factors were identical. SIRS phenomenon after ECMO decannulation commonly occurs. Differentiating between the similar clinical presentations of SIRS and infection is important and will impact clinical outcomes. Copyright © 2016 Elsevier Inc. All rights reserved.

    The study was conducted to know the significance of brain natriuretic peptide (BNP) for prognosis of septic patients. The subjects were 1000 patients selected in emergency department of Beijing Chaoyang Hospital of the Capital Medical University (Beijing, China) and were classified into 3 groups as follows: systemic inflammatory response syndrome (SIRS), non-SIRS, and sepsis groups. Plasma serum brain natriuretic peptide (BNP) levels and the positive detection rates of BNP were examined. The BNP level of 100 pg/mL or more was regarded as positive, and then the positive detection rates of BNP of these groups were compared. The prognostic values of BNP and APACHE (Acute physiology and chronic health evaluation) II score for the 28-day mortality were investigated, and their cutoff values for death were determined. There were significant differences in the positive detection rates of BNP between any 2 groups and in 28-day mortality between the patients with SIRS and non-SIRS groups. The BNP level had positive correlation to APACHE II score in 3 groups. Brain natriuretic peptide level of more than 113 pg/mL was independent predictor of death in septic patients. The positive rates of BNP in SIRS and septic patients were significantly higher than that of non-SIRS patients, and this is an index for unfavorable prognosis in septic patients.

  9. Elementary proof of convergence to the mean-field model for the SIR process.

    The susceptible-infected-recovered (SIR) model has been used extensively to model disease spread and other processes. Despite the widespread usage of this ordinary differential equation (ODE) based model which represents the mean-field approximation of the underlying stochastic SIR process on contact networks, only few rigorous approaches exist and these use complex semigroup and martingale techniques to prove that the expected fraction of the susceptible and infected nodes of the stochastic SIR process on a complete graph converges as the number of nodes increases to the solution of the mean-field ODE model. Extending the elementary proof of convergence for the SIS process introduced by Armbruster and Beck (IMA J Appl Math, doi: 10.1093/imamat/hxw010 , 2016) to the SIR process, we show convergence using only a system of three ODEs, simple probabilistic inequalities, and basic ODE theory. Our approach can also be generalized to many other types of compartmental models (e.g., susceptible-infected-recovered-susceptible (SIRS)) which are linear ODEs with the addition of quadratic terms for the number of new infections similar to the SI term in the SIR model.

    Systemic inflammatory response syndrome (SIRS) and sepsis as causes of multiple organ dysfunction syndrome (MODS) remain challenging to treat in polytrauma patients. In this study, the focus was set on widely used scoring systems to assess their diagnostic quality. A total of 512 patients (mean age: 39.2 ± 16.2, range: 16-88 years) who had an Injury Severity Score (ISS) ≥17 were included in this retrospective study. The patients were subdivided into four groups: no SIRS, slight SIRS, severe SIRS, and sepsis. The ISS, New Injury Severity Score (NISS), Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, and prothrombin time were collected at admission. The Kruskal-Wallis test and χ(2)-test, multinomial regression analysis, and kernel density estimates were performed. Receiver operating characteristic (ROC) analysis is reported as the area under the curve (AUC). Data were considered as significant if p SIRS severity for NISS (slight vs. no SIRS, 1.06, p = 0.07; severe vs. no SIRS, 1.07, p = 0.04; and sepsis vs. no SIRS, 1.11, p = 0.0028) and APACHE II score (slight vs. no SIRS, 0.97, p = 0.44; severe vs. no SIRS, 1.08, p = 0.02; and sepsis vs. no SIRS, 1.12, p = 0.0028). ROC analysis revealed that the NISS (slight vs. no SIRS, AUC 0.61; severe vs. no SIRS, AUC 0.67; and sepsis vs. no SIRS, AUC 0.77) and APACHE II score (slight vs. no SIRS, AUC 0.60; severe vs. no SIRS, AUC 0.74; and sepsis vs. no SIRS, AUC 0.82) had the best predictive ability for SIRS and sepsis. Quick assessment with the NISS or APACHE II score could preselect possible candidates for sepsis following polytrauma and provide guidance in trauma surgeons' decision-making.

  11. HST1 increases replicative lifespan of a sir2Δ mutant in the absence of PDE2 in Saccharomyces cerevisiae.

    Silent information regulator 2 (Sir2), which is the founding member of the sirtuin family of proteins, is a pro-longevity factor for replicative lifespan (RLS) in Saccharomyces cerevisiae. Sir2 is required for transcriptional silencing at mating type loci, telomeres, and rDNA loci. Sir2 also represses transcription of highly expressed growth-related genes, such as PMA1 and some ribosomal protein genes. Although the Sir2 paralogues Hst1, Hst2, Hst3, and Hst4 occur in S. cerevisiae, none of them could replace the transcriptional regulation of PMA1 by Sir2 in the wild type. In this study, we demonstrate that Hst1, the closest Sir2 paralogue, deacetylates the acetylated lysine 16 of histone H4 (H4K16Ac) and represses PMA1 transcription in the sir2Δ pde2Δ mutant. We further show that Hst1 plays a role in extending the RLS of the sir2Δ pde2Δ mutant. Collectively, our results suggest that Hst1 can substitute for Sir2 by deacetylating H4K16Ac only in the sir2Δ pde2Δ.

    Sepsis is frequently observed in patients with alcoholic hepatitis (AH) and is an important mortality predictor. Several studies have also identified systemic inflammatory response syndrome (SIRS) as a significant prognostic factor. The aim of this study was to systematically review and quantify the effect of SIRS and sepsis on mortality in patients with AH. MEDLINE and EMBASE were searched from its inception till January 2016. Participants in the included studies were adults with AH and those with developed SIRS or sepsis during hospitalization. We estimated the risk ratio (RR) with a 95% confidence interval (CI) of mortality by comparing participants with SIRS vs. non-SIRS and sepsis vs. non-sepsis. Data were extracted from six studies involving 1,264 patients (of whom 507 had SIRS) and four studies involving 57,529 patients (of whom 1,449 had sepsis). SIRS and sepsis were both significantly associated with mortality with RRs of 2.7 (95% CI 1.74-4.14, I2=50%) and 2.8 (95% CI 1.58-4.93, I2=94%), respectively. Not only is sepsis associated with mortality but also SIRS. SIRS may be the initial trigger of cascade events leading to mortality in patients with AH. Identification of the key element of SIRS may thus provide a potential therapeutic target.

    Full text of publication follows. Introduction: Selective Internal Radiation Therapy (SIRT) is a promising technique for solid hepatic neoplasms treatment. SIRT consists in implanting radioactive microspheres (RMS) in targeted hepatic lesions via femoral artery. Two RMS-Therapsheres [glass-microspheres/TSR] and Sir-Spheres [resin-spheres/SSR]- are marketed in the European market, both radiolabeled with Yttrium-90. The objective of this study is to assess occupational exposure for nuclear medicine, radiology and clinical staff involved in Y 90 -RMS preparation and implantation. Materials and methods: The study was conducted on 20 patients treated for Hepato-Cellular Carcinoma: 10 treated with TSR and 10 with SSR. Dose rate (DR, mSv/h) or absorbed doses (mSv) measurements were made during all steps of TSR and SSR handling: sources receipt and unpacking, preparation, transport to radiology, implantation, and patient care. Measurements were made with portable ionization chamber(Babyline/Nardeux), spectrometer(FieldSpect/Aries), digital dosimeter (NED/Unfors) and operational dosimeter (Mk2/Siemens). Values were expressed as mean±SD. Results: patients received of 1.8 GBq to 3.1 GBq of TSR and 0.55 GBq to 2.4 GBq of SSR. TSR were delivered ready-to-use with the prescribed activity. For SSR only one activity was commercially available and shipped (3 GBq at calibration-time)requiring a preparation step to adjust needed activity. DR measured during RMS was 1723 ± 157 μSv/h SSR and 1189 ± 92 μSv/h for TSR. When preparing spheres in radiopharmacy, fingers and whole body doses were respectively 8326 ± 2360 μSv and 12.3 ± 5,2 μSv for Sir-Spheres vs. 33.5 ± 7.8 μSv and 1.1 ± 0.3 μSv for TSR. DR in contact with carrying case during RMS transfer to radiology were 299 ± 102 μSv/h for SSR and 5.3 ± 1.2 μSv/h for TSR. During RMS infusion, radiologist's finger doses were limited to 3.6 ± 1 μSv for SSR and 0.7± 0.3 μSv for TSR. Finally, following RMS

    We develop a multi-group epidemic framework via virtual dispersal where the risk of infection is a function of the residence time and local environmental risk. This novel approach eliminates the need to define and measure contact rates that are used in the traditional multi-group epidemic models with heterogeneous mixing. We apply this approach to a general n-patch SIS model whose basic reproduction number [Formula: see text] is computed as a function of a patch residence-time matrix [Formula: see text]. Our analysis implies that the resulting n-patch SIS model has robust dynamics when patches are strongly connected: There is a unique globally stable endemic equilibrium when [Formula: see text], while the disease-free equilibrium is globally stable when [Formula: see text]. Our further analysis indicates that the dispersal behavior described by the residence-time matrix [Formula: see text] has profound effects on the disease dynamics at the single patch level with consequences that proper dispersal behavior along with the local environmental risk can either promote or eliminate the endemic in particular patches. Our work highlights the impact of residence-time matrix if the patches are not strongly connected. Our framework can be generalized in other endemic and disease outbreak models. As an illustration, we apply our framework to a two-patch SIR single-outbreak epidemic model where the process of disease invasion is connected to the final epidemic size relationship. We also explore the impact of disease-prevalence-driven decision using a phenomenological modeling approach in order to contrast the role of constant versus state-dependent [Formula: see text] on disease dynamics.

    2008-02-01

    Almost a century ago, William Osler, the foremost physician of his time, was approached by a leading periodical to write a series of articles on the health of the American woman. Osler, then the Regius Professor of Medicine at Oxford, wrote an essay dealing with the psychological stresses affecting the "new woman" of the early 20th century at varying stages of her development and the "nervousness" that ensued. The article was never published as a result of his belated reservations on the propriety of a professional writing for a lay journal. Osler's thinking frequently reflected the spirit of his Victorian-Edwardian era, although at times he demonstrated advanced and prescient ideas about sexuality, not often the subject of discussion, even in circumspect form, in contemporary nonprofessional literature.

    The Wood's lamp aids in the diagnosis of multiple infectious, inflammatory and neoplastic dermatologic conditions. Although the Wood's lamp has many applications, which have improved both the diagnosis and management of disease, the man credited for its invention is relatively unknown in medicine. Robert Williams Wood, a prominent physicist of the early 20th century, is credited for the invention of the Wood's lamp. Wood was the father of infrared and ultraviolet photography and made significant contributions to other areas in optics and spectroscopy. Wood's work encompassed the formative years of American Physics; he published over 200 original papers over his lifetime. A few years after the invention of the Wood's lamp for ultraviolet photography, physicians in Europe adopted the Wood's lamp for dermatologic applications. Wood's lamp remains popular in clinics globally, given its ease of use and ability to improve diagnostic precision. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Medicine and literature have always been connected over the ages. William Shakespeare (1564-1616 is no exception. There are plenty of references to medicine and diseases in the works of Shakespeare. The knowledge which Shakespeare has of medical conditions is much more than is expected of a common man. This is attributed to his association with practitioners of his time and reading of contemporary texts in medicine. Also his son in law Dr. John Hall who married Susanna, Shakespeare's eldest daughter would have contributed substantially to the knowledge of medicine in Shakespeare's compositions. Surgery at the Elizabethan times was well known and is reflected to a large extent in his plays.

    It is not at all unusual for a wealthy aristocrat to provide substantial funds for building an academic institution. But it is highly unusual that the aristocrat concerned should have been steeped in the education, science and industry for which the institution would become justly famous. The man who provided all the necessary funds to build and equip the Cavendish Laboratory at Cambridge University in the UK was William Cavendish, who succeeded his father's cousin as 7th Duke of Devonshire in 1858 and became chancellor of the university in 1861. He had crowned his own undergraduate career at Cambridge in 1829 at Trinity College with the awards of second Wrangler and first Smiths Prize, and in the same year, aged just 21, was elected a fellow of the Royal Society.

    Williams syndrome (WS) is a neuro-developmental disorder which is characterized by an unusual fractionation of language abilities and other cognitive functions. We have investigated four cases of English-speaking subjects with WS, and we show that despite their low IQs the WS children's performance on syntactic tasks and on regular inflection is not impaired. Irregular inflection, however, is affected causing many errors. We also report results from studies investigating the same linguistic phenomena in children with specific language impairment. These children exhibit a different pattern of impairment, with relatively poor performance on syntactic tasks and regular inflection. We suggest a linguistic characterization of the morphosyntax in WS according to which WS subjects are impaired in accessing (particular kinds of) information from lexical entries, with their computational system for language appearing to be intact. We interpret the selective impairments found in WS and SLI as supporting the theoretical distinction between a computational system and an associative memory system for language.

    Full Text Available Human beings have never been satisfied with this ephemeral world. Perhaps, yearning and desire of rejoining −stemming from the descent from the heaven to the earth− are the emotions felt by the members of both celestial and non-celestial religions. Mysticism, having started with the zeal of people who weren‘t satisfied with this ephemeral world towards the eternal world, aimed at the love of God in the religions where there is a belief of single God. In this article, glancing at the life of a Christian mystic William Blake, we will try to shed light into his mystic thoughts. While studying Blake‘s mystic thoughts, there will be common points with Sufism. Nevertheless, analysis of these common points has been assigned to other studies.

It was nearly 40 years since he arrived in Canton (Guangzhou) in 1909 and left at retirement age. He taught western medicine in Canton Christian College and worked as a medical doctor in Canton Hospital, the oldest western medical hospital in the Orient. He was regarded as a famous foreign doctor and an excellent professor in internal medicine in the Republic of China. He wrote At the point of Lancet: 100 years of Canton Hospital 1835 - 1935, which recorded the achievement made by American missionary doctors, particularly the pioneers such as Peter Parker M.D. and John G. Kerr. M.D. So far the book is still an important reference for the studies on history of western medicine in China and the history of modern medical exchange between China and other countries.

    The Spaceborne Imaging Radar-C (SIR-C) was a radar system, which successfully operated on two separate shuttle missions in April and October 1994. During these two missions, a total of 143 hours of radar data were recorded. SIR-C was the first multifrequency and polarimetric spaceborne radar system, operating in dual frequency (L- and C- band) and with quad-polarization. SIR-C had a variety of different operating modes, which are innovative even from today's point of view. Depending on the mode, it was possible to acquire data with different polarizations and carrier frequency combinations. Additionally, different swaths and bandwidths could be used during the data collection and it was possible to receive data with two antennas in the along-track direction.The United States Geological Survey (USGS) distributes the synthetic aperture radar (SAR) images as single-look complex (SLC) and multi-look complex (MLC) products. Unfortunately, since June 2005 the SIR-C processor has been inoperable and not repairable. All acquired SLC and MLC images were processed with a course resolution of 100 m with the goal of generating a quick look. These images are however not well suited for scientific analysis. Only a small percentage of the acquired data has been processed as full resolution SAR images and the unprocessed high resolution data cannot be processed any more at the moment.At the Alaska Satellite Facility (ASF) a new processor was developed to process binary SIR-C data to full resolution SAR images. ASF is planning to process the entire recoverable SIR-C archive to full resolution SLCs, MLCs and high resolution geocoded image products. ASF will make these products available to the science community through their existing data archiving and distribution system.The final paper will describe the new processor and analyze the challenges of reprocessing the SIR-C data.

    In acetaminophen-induced acute liver failure (ALF), the hepatic coma grade worsens and mortality rates increase, as the number of systemic inflammatory response syndrome components fulfilled (SIRS score) increases. This study aimed to investigate the impact of SIRS score on clinical features of non-acetaminophen-related ALF. Ninety-nine patients with non-acetaminophen-related ALF with hepatic coma who did not undergo liver transplantation were investigated. Each patient was given a SIRS score of 0, 1, 2, 3 or 4 at the time of diagnosis. At the diagnosis of ALF with hepatic coma, with the increase of SIRS score, hepatic coma grade and prothrombin activity were deteriorated. After the diagnosis of ALF with hepatic coma, 25 patients (25%) developed acute respiratory distress syndrome (ARDS), 31 patients (31%) developed disseminated intravascular coagulation (DIC), and 21 patients (22%) developed acute renal failure (ARF). Thirty-eight patients (38%) developed MOF. With the increase of SIRS score, frequencies of the development of ARDS, DIC and MOF increased. ARF was more frequently developed in patients with a SIRS score of 2 or higher. Overall, 36 patients (36%) survived. Overall survival rate was 66% in 29 patients with a score of 0, 43% in 21 patients with a score of 1, 17% in 29 patients with a score of 2 and 15% in 20 patients with a score of 3 or 4. SIRS score will be useful for predicting not only the overall survival but also the development of complications such as ARDS, DIC and MOF in non-acetaminophen-related ALF with hepatic coma.

    This study was designed to identify changes in the monocytic membrane marker HLA-DR and heat shock proteins (HSPs) in relation to T-regulatory cells (T-regs) and other immunological marker changes in patients with systemic inflammatory response syndrome (SIRS) or sepsis/septic shock. Healthy volunteers, intensive care unit (ICU) patients with SIRS due to head injury and ICU patients with severe sepsis/septic shock were enrolled in the current study. Determination of CD14+/HLA-DR+ cells, intracellular heat-shock proteins and other immunological parameters were performed by flow cytometry and RT-PCR techniques as appropriate. Univariate and multivariate analysis examined associations of CD14/HLA-DR, HSPs, T-regs and suppressor of cytokine signalling (SOCS) proteins with SIRS, sepsis and outcome. Fifty patients (37 with severe sepsis and 13 with SIRS) were enrolled, together with 20 healthy volunteers used as a control group. Compared to healthy individuals, patients with SIRS and severe sepsis showed progressive decline of their CD14/HLA-DR expression (0% to 7.7% to 50% within each study subpopulation, pSIRS patients compared to controls and fell significantly in severe sepsis/septic shock patients (pSIRS and sepsis were found for CD14/HLA-DR expression and monocyte and polymorphonuclear cell levels of HSP70 and 90. The role of these biomarkers in assessing the prognosis of sepsis needs to be further explored and validated in prospective studies. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Retinal stem cells bear potency of proliferation, self-renewal, and differentiation into many retinal cells. Utilizing appropriate sensors one can effectively detect the self-renewal and aging process abilities. Silencing information regulator (SirT1, a member of the sirtuin family, is a NAD-dependent histone deacetylase and an essential mediator for longevity in normal cells by calorie restriction. We firstly investigate the SirT1 mRNA expression in retinal stem cells from rats and 19 human eyes of different ages. Results revealed that SirT1 expression was significantly decreased in in vivo aged eyes, associated with poor self-renewal abilities. Additionally, SirT1 mRNA levels were dose-dependently increased in resveratrol- treated retinal stem cells. The expression of SirT1 on oxidative stress-induced damage was significantly decreased, negatively correlated with the level of intracellular reactive oxygen species production. Treatment with resveratrol could effectively further reduce oxidative stress induced by H2O2 treatment in retinal stem cells. Importantly, the anti-oxidant effects of resveratrol in H2O2-treated retinal stem cells were significantly abolished by knockdown of SirT1 expression (sh-SirT1. SirT1 expression provides a feasible sensor in assessing self-renewal and aging process in retinal stem cells. Resveratrol can prevent reactive oxygen species-induced damages via increased retinal SirT1 expression.

    Full Text Available Differentiating sepsis from other noninfectious causes of systemic inflammation is often difficult in the elderly. The aim of this study was to evaluate the ability of C-reactive protein (CRP, Erythrocyte Sedimentation Rate (ESR, procalcitonin (PCT, and Interleukin-6 (IL-6 to identify elderly patients with sepsis. In this single center prospective observational study, we included all consecutive elderly patients admitted with suspected sepsis and systemic inflammatory response syndrome (SIRS in an emergency department. Blood samples for measuring CRP, PCT, IL-6, ESR and white blood cells (WBC count were taken at first day of admission. Sensitivity, specificity, positive and negative predictive values were calculated for each inflammatory markers being studied. A total of 150 elderly patients aged 65 and older, 50 with sepsis and 50 with SIRS, and fifty individuals in a normal health status were included. CRP exhibited the greatest sensitivity (98% and negative predictive value (98.6% and performed best in differentiating patients with sepsis from those with SIRS. In a receiver operating characteristic curve analysis, IL-6 performed best in distinguishing between SIRS and the control group (AUC 0.75, 95% CI. On the other hand, both CRP and ESR appeared to be a more accurate diagnostic parameter for differentiating sepsis from SIRS among elderly patients.

    Full Text Available As an epidemic mathematical model, the SIR model represents the transition of the Susceptible, Infected, and Recovered. The profound implication of the SIR model is viewed as the propagation and dynamic evolutionary process of the different internal components and the characteristics in a complex system subject to external effect. The uniaxial stress-strain curve of engineering material represents the basic constitutive relation, which also represents the damage propagation in the units of the damaged member. Hence, a novel dynamic stress-strain model is established based on the SIR model. The analytical solution and the approximate solution for the proposed model are represented according to the homotopy analysis method (HAM, and the relationship of the solution and the size effect and the strain rate is discussed. In addition, an experiment on the size effect of confined concrete is carried out and the solution of SIR model is suitable for simulation. The results show that the mechanical mechanism of the parameters of the uniaxial stress-strain model proposed in this paper reflects the actual characteristics of the materials. The solution of the SIR model can fully and accurately show the change of the mechanical performance and the influence of the size effect and the strain rate.

    Early recognition of severe form of acute pancreatitis is important because these patients need more agressive diagnostic and therapeutical approach an can develope systemic complications such as: sepsis, coagulopathy, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), Multiple Organ Dysfunction Syndrome (MODS), Multiple Organ Failure (MOF). To determine role of the combination of Systemic Inflammatory Response Syndrome (SIRS) score and serum Interleukin-6 (IL-6) level on admission as predictor of illness severity and outcome of Severe Acute Pancreatitis (SAP). We evaluated 234 patients with first onset of SAP appears in last twenty four hours. A total of 77 (33%) patients died. SIRS score and serum IL-6 concentration were measured in first hour after admission. In 105 patients with SIRS score 3 and higher, initial measured IL-6 levels were significantly higher than in the group of remaining 129 patients (72 +/- 67 pg/mL, vs 18 +/- 15 pg/mL). All nonsurvivals were in the first group, with SIRS score 3 and 4 and initial IL-6 concentration 113 +/- 27 pg/mL. The values of C-reactive Protein (CRP) measured after 48h, Acute Physiology and Chronic Health Evaluation (APACHE II) score on admission and Ranson score showed the similar correlation, but serum amylase level did not correlate significantly with Ranson score, IL-6 concentration and APACHE II score. The combination of SIRS score on admission and IL-6 serum concentration can be early, predictor of illness severity and outcome in SAP.

    Fibroblast growth factor 21 (FGF21) is a key regulator in glucose and lipid metabolism and its plasma levels have been shown to be increased not only in humans in different situations such as type 2 diabetes, obesity, and nonalcoholic fatty liver disease but also in animal models of sepsis and pancreatitis. FGF21 is considered as a pharmacological candidate in conditions associated with insulin resistance. The aim of this study was to compare FGF21 plasma levels in patients with sepsis, in patients with systemic inflammatory response syndrome (SIRS), and in healthy controls. We measured FGF21 plasma concentrations in 22 patients with established sepsis, in 11 with SIRS, and in 12 healthy volunteers. Here, we show that FGF21 levels were significantly higher in plasma obtained from patients with sepsis and SIRS in comparison with healthy controls. Also, FGF21 levels were significantly higher in patients with sepsis than in those with noninfectious SIRS. FGF21 plasma levels measured at study entry correlated positively with the APACHE II score, but not with procalcitonin levels, nor with C-reactive protein, classical markers of sepsis. Plasma concentrations of FGF21 peaked near the onset of shock and rapidly decreased with clinical improvement. Taken together, these results indicate that circulating levels of FGF21 are increased in patients presenting with sepsis and SIRS, and suggest a role for FGF21 in inflammation. Further studies are needed to explore the potential role of FGF21 in sepsis as a potential therapeutic target.

    Full Text Available Considerando que la fuerza divina es un poder propiamente humano, que permite trascender desde la mera visualización y percepción sensorial del mundo finito y terrenal hacia el reino eterno y verdadero de la imaginación, el poeta, artista y visionario inglés William Blake (1757-1827 identificó a dios con dicha facultad humana. En su lucha contra la ‘religión de la razón’, bajo cuyo poder el hombre se había limitado a la ‘vacía’ percepción exterior, Blake buscará recobrar la ‘religión de la imaginación’. Desde esta perspectiva, este estudio pretende dilucidar el modo en que la materialidad de lo escrito (Roger Chartier y la utilización de un método de escritura particular por parte del visionario -distinto al que su propio tiempo le ofrecía- afecta el circuito de la comunicación visionaria de comienzo a fin, relacionándose directamente con la finalidad que Blake otorgó a sus poemas proféticos iluminados: despertar en los lectores esa capacidad visionaria y verdadera que ‘reside en el pecho de todos los hombres’.Considering the ‘divine force’ as a human power that allows humans to transcend from the mere sensory visualization and perception of the finite and earthly world to the true and eternal realm of imagination, William Blake, the english poet, artist and visionary (1757-1827 identified god with this human faculty.

    Currently, there is no biomarker that can reliable distinguish between infectious and non-infectious systemic inflammatory response syndrome (SIRS). However, such a biomarker would be of utmost importance for early identification and stratification of patients at risk to initiate timely and appropriate antibiotic treatment. Within this proof of principle study, the high potential of Raman spectroscopy for the fast differentiation of non-infectious SIRS and sepsis is demonstrated. Blood plasma collected from 70 patients from the intensive care unit (31 patients with sepsis and 39 patients classified with SIRS without infection) was analyzed by means of Raman spectroscopy. A PCA-LDA based classification model was trained with Raman spectra from test samples and yielded for sepsis a sensitivity of 1.0 and specificity of 0.82. These results have been confirmed with an independent dataset (prediction accuracy 80%). Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    1988-01-01

    A digital cartographic multisensor image database of excellent geometry and improved resolution was created by registering SIR-B images to a rectified Landsat TM reference image and applying intensity-hue-saturation enhancement techniques. When evaluated against geodetic control, RMSE(XY) values of approximately + or - 20 m were noted for the composite SIR-B/TM images. The completeness of cartographic features extracted from the composite images exceeded those obtained from separate SIR-B and TM image data sets by approximately 10 and 25 percent, respectively, indicating that the composite images may prove suitable for planimetric mapping at a scale of 1:100,000 or smaller. At present, the most effective method for extracting cartographic information involves digitizing features directly from the image processing display screen.

    The Quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA) score has been shown to accurately predict mortality in septic patients and is part of recently proposed diagnostic criteria for sepsis. We sought to ascertain the sensitive of the score in diagnosing sepsis, as well as the diagnostic timeliness of the score when compared to traditional systemic inflammatory response syndrome (SIRS) criteria in a population of emergency department (ED) patients treated in the ED, admitted, and subsequently discharged with a diagnosis of sepsis. Electronic health records of 200 patients who were treated for suspected sepsis in our ED and ultimately discharged from our hospital with a diagnosis of sepsis were randomly selected for review from a population of adult ED patients (N=1880). Data extracted included the presence of SIRS criteria and the qSOFA score as well as time required to meet said criteria. In this cohort, 94.5% met SIRS criteria while in the ED whereas only 58.3% met qSOFA. The mean time from arrival to SIRS documentation was 47.1min (95% CI: 36.5-57.8) compared to 84.0min (95% CI: 62.2-105.8) for qSOFA. The median ED "door" to positive SIRS criteria was 12min and 29min for qSOFA. Although qSOFA may be valuable in predicting sepsis-related mortality, it performed poorly as a screening tool for identifying sepsis in the ED. As the time to meet qSOFA criteria was significantly longer than for SIRS, relying on qSOFA alone may delay initiation of evidence-based interventions known to improve sepsis-related outcomes.

    Full Text Available Chagas disease remains one of the most neglected diseases in the world despite being the most important parasitic disease in Latin America. The characteristic chronic manifestation of chagasic cardiomyopathy is the region's leading cause of heart-related illness, causing significant mortality and morbidity. Due to the limited available therapeutic options, new drugs are urgently needed to control the disease. Sirtuins, also called Silent information regulator 2 (Sir2 proteins have long been suggested as interesting targets to treat different diseases, including parasitic infections. Recent studies on Trypanosoma cruzi sirtuins have hinted at the possibility to exploit these enzymes as a possible drug targets. In the present work, the T. cruzi Sir2 related protein 1 (TcSir2rp1 is genetically validated as a drug target and biochemically characterized for its NAD+-dependent deacetylase activity and its inhibition by the classic sirtuin inhibitor nicotinamide, as well as by bisnaphthalimidopropyl (BNIP derivatives, a class of parasite sirtuin inhibitors. BNIPs ability to inhibit TcSir2rp1, and anti-parasitic activity against T. cruzi amastigotes in vitro were investigated. The compound BNIP Spermidine (BNIPSpd (9, was found to be the most potent inhibitor of TcSir2rp1. Moreover, this compound showed altered trypanocidal activity against TcSir2rp1 overexpressing epimastigotes and anti-parasitic activity similar to the reference drug benznidazole against the medically important amastigotes, while having the highest selectivity index amongst the compounds tested. Unfortunately, BNIPSpd failed to treat a mouse model of Chagas disease, possibly due to its pharmacokinetic profile. Medicinal chemistry modifications of the compound, as well as alternative formulations may improve activity and pharmacokinetics in the future. Additionally, an initial TcSIR2rp1 model in complex with p53 peptide substrate was obtained from low resolution X-ray data (3.5 Å to

    A shortcut review was carried out to establish whether serum procalcitonin levels can be used to identify serious bacterial infection in ED patients with undifferentiated SIRS. 14 papers presented the best evidence to answer the clinical question. The review concludes that raised procalcitonin levels are associated with bacteraemia; however, there are no clinical management studies addressing this question in ED patients with SIRS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Geologic environments of the Williams Quadrangle, Arizona, were evaluated for uranium favorability by means of literature research, uranium-occurrence investigation and other surface studies, subsurface studies, aerial radiometric data, hydrogeochemical data, and rock-sample analytic data. Favorability criteria are those of the National Uranium Resource Evaluation program. Three geologic environments are favorable for uranium: the Tertiary fluvial rocks of the Colorado Plateau where they unconformably overlie impermeable bed rock (for channel-controlled peneconcordant deposits); collapse breccia pipes in Paleozoic strata of the Colorado Plateau (for vein-type deposits in sedimentary rocks); and Precambrian crystalline rocks of the Hualapai, Peacock, and Aquarius Mountains, and Cottonwood and Grand Wash Cliffs (for magmatic-hydrothermal deposits). Unfavorable geologic environments are: Tertiary and Quaternary volcanic rocks, Tertiary and Quaternary sedimentary rocks of the Colorado Plateau, nearly all Paleozoic and Mesozoic sedimentary rocks, and the Precambrian-Cambrian unconformity of the Grand Wash Cliffs area. Tertiary rocks in Cenozoic basins and Precambrian crystalline rocks in the Grand Canyon region and in parts of the Aquarius Mountains and Cottonwood and Grand Wash Cliffs are unevaluated

Bill demonstrated expertise in a wide range of fields, with a highly productive and creative research and writing career that included geology, oceanography, climatology, atmospheric physics, and meteorology.Donn was born in Brooklyn, N.Y., on March 2, 1918. At the tender age of 10 years, he demonstrated his love and talent for science by building a telescope with his brother, Bertram. During his undergraduate years at Brooklyn College, he switched his major from astronomy to geology. He was largely selftrained in both meteorology and oceanography, serving as head of the Meteorology Section, U.S. Merchant Marine Academy during World War II . One by-product of these years was the textbook Meteorology—With Marine Applications, first published in 1946. This widely adopted text became a standard for a generation of mariners and college students.

    Congenital amusia is defined by marked deficits in pitch perception and production. Though historically examined only in otherwise typically developing (TD) populations, amusia has recently been documented in Williams syndrome (WS), a genetic, neurodevelopmental disorder with a unique auditory phenotype including auditory sensitivities and increased emotional responsiveness to music but variable musical skill. The current study used structural T1-weighted magnetic resonance imaging and diffusion tensor imaging to examine neural correlates of amusia in 17 individuals with WS (4 of whom met criteria for amusia). Consistent with findings from TD amusics, amusia in WS was associated with decreased fractional anisotropy (FA) in the right superior longitudinal fasciculus (SLF). The relationship between amusia and FA in the inferior component of the SLF was particularly robust, withstanding corrections for cognitive functioning, auditory sensitivities, or musical training. Though the number of individuals with amusia in the study is small, results add to evidence for the role of fronto-temporal disconnectivity in congenital amusia and suggest that novel populations with developmental differences can provide a window into understanding gene-brain-behavior relationships that underlie musical behaviors.

  18. Porters, watchmen, and the crime of William Sayers: the non-scientific staff of the Royal Observatory, Greenwich, in Victorian times

    Chapman, Allan

    2003-06-01

    A careful study of the detailed archives of the Victorian Royal Observatory makes it possible to build up a picture of the employment and working conditions not only of the astronomical staff who worked at Greenwich, but also of the labourers, watchmen, and gate porters. Indeed, the archives open up a window on to how the Observatory was run on a daily basis: how its non-scientific staff were recruited and paid, and what were their terms of employment. They also say a great deal about how Sir George Biddell Airy directed and controlled every aspect of the Observatory's life. Yet while Airy was a strict employer, he emerges as a man who was undoubtedly fair-minded and sometimes even generous to his non-scientific work-force. A study of the Observatory staff files also reveals the relationship between the Observatory labouring staff and the Airy family's domestic servants. And of especial interest is the robbery committed by William Sayers, the Airy family footman in 1868, bringing to light as it does Sir George and Lady Richarda Airy's views on crime and its social causes and consequences, the prison rehabilitation service in 1868, and their opinions on the reform of offenders. Though this paper is not about astronomy as such, it illuminates a fascinating interface where the world of astronomical science met and worked alongside the world of ordinary Victorian people within the walls of one of the nineteenth century's most illustrious astronomical institutions.

    Systemic inflammatory response syndrome (SIRS) development is accompanied by mitochondrial dysfunction and excessive ROS production. Mitochondrial dysfunctions also occur in many SIRS-related diseases and may be critical for their pathogenesis; therefore, a use of mitochondria-targeted drugs is a promising trend in SIRS research and therapy. Here, we review recent studies concerning the application of the mitochondria-targeted antioxidants and uncouplers of oxidative phosphorylation in animal models of SIRS and related diseases. We propose that a new class of uncouplers of oxidative phosphorylation, lipophilic cations could be a base for a new generation of drugs for SIRS treatment. J. Cell.

  1. William Byrd: Political and Recusant Composer

    2012-05-01

    Full Text Available Amidst the pendulum of political and religious upheaval that pervaded England throughout the sixteenth and seventeenth century, William Byrd stands as one of the best loved and lauded composers. Byrd succeeded in the secular and sacred realms, contributing great works to the Anglican Church, popularizing the English madrigal and producing prolific amounts of sacred music. However, in a time where one’s religious beliefs were often linked with political loyalty, Byrd defied his monarch’s established and enforced Protestant religion, composing politically charged music for recusant use in clandestine Catholic Church services. His themes were aligned with the Jesuit mission and his texts were often drawn from the lips of martyred Catholics at the gallows; their last words forever immortalized by Byrd for the furthering of the Jesuit cause and the Counter-Reformation. The examination of sources by prominent Byrd scholars, an analyses of Byrd’s ‘political’ compositions and a study of the social and historical background are used to place Byrd within the appropriate context, prove his recusant and political leanings, and analyze his precarious relationship with the English monarch, Elizabeth I. It is shown that Byrd could not have proceeded with his recusant practices, personally or musically, had it not been for his status as a composer, as well as Byrd’s shrewdness in procuring diplomatic relationships with high persons at court and with Queen Elizabeth I through the Chapel Royal. Finally, Byrd’s success at writing for the Anglican Church service and popular secular music showcased his ability to take a moderate stance in situations that benefitted his status with the crown

As part of that endeavor, James’s unorthodox scientific pursuits, from his experiments with nitrous oxide and hallucinogenic drugs to his investigation of spiritualist mediums, represent his attempt to address the “hard problems” of consciousness for which his training in brain physiology and experimental psychology could not entirely account. As a student, James’s reading in chemistry and physics had sparked his interest in the concepts of energy and force, terms that he later deployed in his writing about consciousness and in his arguments against philosophical monism and scientific materialism, as he developed his “radically empiricist” ideas privileging discontinuity and plurality. Despite James’s long campaign against scientific materialism, he was, however, convinced of the existence of a naturalistic explanation for the more “wayward and fitful” aspects of mind, including transcendent experiences associated with hysteria, genius, and religious ecstasy. In this paper, I examine aspects of James’s thought that are still important for contemporary debates in psychology and neuroscience: his “transmission theory” of consciousness, his ideas on the “knowing of things together,” and, finally, the related concept of “the compounding of consciousness,” which postulates the theoretical possibility for individual entities within a conscious system of thought to “know” the thoughts of others within the system. Taken together, these ideas suggest that James, in spite of, or perhaps because of, his forays into metaphysics, was working toward a naturalistic understanding of consciousness, what I will term a “distributive model,” based on his understanding of consciousness as an “awareness” that interacts dynamically within, and in relation to

    FoxO transcription factors and sirtuin family deacetylases regulate diverse biological processes, including stress responses and longevity. Here we show that the Caenorhabditis elegans sirtuin SIR-2.4--homolog of mammalian SIRT6 and SIRT7 proteins--promotes DAF-16-dependent transcription and stress-induced DAF-16 nuclear localization. SIR-2.4 is required for resistance to multiple stressors: heat shock, oxidative insult, and proteotoxicity. By contrast, SIR-2.4 is largely dispensable for DAF-16 nuclear localization and function in response to reduced insulin/IGF-1-like signaling. Although acetylation is known to regulate localization and activity of mammalian FoxO proteins, this modification has not been previously described on DAF-16. We find that DAF-16 is hyperacetylated in sir-2.4 mutants. Conversely, DAF-16 is acetylated by the acetyltransferase CBP-1, and DAF-16 is hypoacetylated and constitutively nuclear in response to cbp-1 inhibition. Surprisingly, a SIR-2.4 catalytic mutant efficiently rescues the DAF-16 localization defect in sir-2.4 null animals. Acetylation of DAF-16 by CBP-1 in vitro is inhibited by either wild-type or mutant SIR-2.4, suggesting that SIR-2.4 regulates DAF-16 acetylation indirectly, by preventing CBP-1-mediated acetylation under stress conditions. Taken together, our results identify SIR-2.4 as a critical regulator of DAF-16 specifically in the context of stress responses. Furthermore, they reveal a novel role for acetylation, modulated by the antagonistic activities of CBP-1 and SIR-2.4, in modulating DAF-16 localization and function.

    Recently, increasing emphasis is being placed upon assessment of the inflammatory status of the patient. Serum inflammatory cytokines, particularly IL-6, have been used as an adjunct to this assessment. Another method uses a combination of simple laboratory and clinical data to provide an assessment of the patient's current level of systemic inflammation, the SIRS. The aim of this study was to investigate, in a group of adult trauma patients, the relationship between the interleukin-6 (IL-6) concentration, the systemic inflammatory response score (SIRS) and outcome. In patients with femoral shaft fracture, serum IL-6 levels and clinical parameters were recorded prospectively on admission and on days 1, 3, 5, and 7. Clinical course, the SIRS score and complications were documented. Nonparametric tests were used to assess relationships between variables and receiver operator characteristic (ROC) curves were used to examine their predictive values. Significance was assumed at the p SIRS state" detected early (day 1 and 3) positively correlated with the IL-6 measurement from the same period (p SIRS state (p SIRS state with an 83% sensitivity and a 75% specificity (area under ROC curve 0.76, p SIRS state and an IL-6 > 300 pg/mL was associated with a significantly increased risk of complication (pneumonia, MOF, death). Both systems were found to be significantly diagnostic of these complications using ROC curve analysis. The IL-6 concentration and SIRS score are useful adjuncts to clinical evaluation of the injured patient. In the early phase, they are closely correlated with the NISS and each other. A cutoff value of 200 pg/dL was shown to be significantly diagnostic of a SIRS state. Significant correlations between adverse events and both the IL-6 level and SIRS state are demonstrated.

    On March 28, 2008, the space research community lost another of its pioneers. William A. Rense, professor emeritus of physics at the University of Colorado in Boulder, who died in Estes Park, Colorado, following complications from cancer. He was 94. Bill, as he was widely known, was born in 1914 in Massillon, Ohio, the son of German immigrants. His was a large family - five brothers and one sister. His father, Joseph Rense, worked for the city of Cleveland while his mother, Rosalia (Luther) Rense was a housewife. As a child, Bill developed a love of astronomy which led him to earn a bachelor's degree in physics and astronomy from Case Western Reserve University in Cleveland, followed by master's and PhD degrees in physics at Ohio State University. He held teaching positions at Rutgers, University of Miami (Florida), Texas A & M, and Louisiana State University before taking his final appointment at CU in 1949. While teaching at LSU, he met and in 1942 married Wanda (Childs) Rense. In addition to teaching physics at CU, Bill did research in CU's Upper Air Laboratory. His early work there included studies of polarized light and its implications for the analysis of zodiacal light. He and his co-workers also began developing instrumentation to be flown above the Earth's atmosphere in sounding rockets. In 1952 he obtained the first photographic spectrogram of the solar Lyman-alpha line of hydrogen (121.6nm). This work was followed in 1956 by the first full disk spectroheliogram in Lyman-alpha. These results could not have been possible without the use of pointing control systems for sounding rockets. These "sun trackers" kept the payloads pointed at the sun long enough for the measurements to be made, and CU was a pioneer in their development. The expanding research venue led the Upper Air Laboratory to be renamed the Laboratory for Atmospheric and Space Physics (LASP), and Bill Rense was its first director. He continued his research into the properties of the solar

    Recent data suggest that both elevated serum chloride levels and volume overload may be harmful during fluid resuscitation. The purpose of this study was to examine the relationship between the intravenous chloride load and in-hospital mortality among patients with systemic inflammatory response syndrome (SIRS), with and without adjustment for the crystalloid volume administered. We conducted a retrospective analysis of 109,836 patients ≥ 18 years old that met criteria for SIRS and received fluid resuscitation with crystalloids. We examined the association between changes in serum chloride concentration, the administered chloride load and fluid volume, and the 'volume-adjusted chloride load' and in-hospital mortality. In general, increases in the serum chloride concentration were associated with increased mortality. Mortality was lowest (3.7%) among patients with minimal increases in serum chloride concentration (0-10 mmol/L) and when the total administered chloride load was low (3.5% among patients receiving 100-200 mmol; P SIRS, a fluid resuscitation strategy employing lower chloride loads was associated with lower in-hospital mortality. This association was independent of the total fluid volume administered and remained significant after adjustment for severity of illness, supporting the hypothesis that crystalloids with lower chloride content may be preferable for managing patients with SIRS.

    Three different 90Y internally administered radionuclide therapies are currently used in both standard-of-care and clinical trial procedures atMD Anderson Cancer Center. TheraSphere and SIR-Spheres therapies utilize 90Y-labeled microspheres, while Zevalin is an 90Y-labeled radioimmunotherapeutic agent. Several publications have indicated radionuclidic impurities resulting from 90Y production methods. The 90Y in SIR-Spheres and Zevalin are produced from a 90Sr/90Y generator, which leaves measurable quantities of 90Sr in the final product. TheraSphere 90Y is produced in a nuclear reactor which results in a large number of impurities, most notably 88Y and 91Y. Product information sheets reference these impurities with specific limits given. These limits represent a tiny fraction of the total product activity, and in the case of TheraSphere and SIR-Spheres gamma-emitting impurities, this has been verified in the literature. An analysis of 90Sr impurities in SIR-Spheres and Zevalin is presented in this paper. Impurity quantities were found to be within the vendors’ documented limits.

    Systemic inflammatory response syndrome (SIRS) is a syndrome that reflects the widespread activation of inflammatory pathways. The goal of this study was to find whether the presence or absence of SIRS on emergency surgical admissions is related to the subsequent clinical outcome in terms of in-hospital interventions, length of stay, and mortality. The presence of SIRS at admission, final diagnosis of the underlying disease, treatments, and clinical outcomes were prospectively recorded for 1 month. Comparisons of interventions and outcomes were performed between SIRS+ vs. SIRS- patients. In patients with SIRS, the contribution of each positive criterion was evaluated with regards to mortality. A total of 179 patients were recruited. The prevalence of SIRS at admission was 35.2%. SIRS+ patients required less diagnostic procedures compared with SIRS- (28.6% vs. 34.5%) but had more therapeutic interventions (39.7% vs. 16.4%), surgical interventions (33.3% vs. 3.4%), intensive treatments (11.1% vs. 0.9%; p SIRS+ patients with four positive criteria had more surgical interventions, intensive treatments, and fatal outcomes compared with the others. Of importance the most influent factor was the respiratory rate followed by the white cell count and the heart rate/temperature. Patients with SIRS at admission apparently receive more interventions, have longer length of stay, and increased mortality than those patients without SIRS. These findings require separate validation in a larger cohort study.

    Full Text Available SIRS Digues is a computing tool that makes informations on levees more durable and accessible in order to enhance their management. The first version of the software, which was IRSTEA’s initiative, was deployed in 2004. The second version was released in 2015. This article aims at pointing out the innovative aspects of this last version. They concern thematic and functionalities, computing technics and architecture, and last but not least, the business model chosen in order to build a long lasting software. The software’s kernel is sketched to propose a general description of levees: it focuses on description of the levees and linked objects, on disorders that affects them, on works... Most of these topics were already broached by the first version. The kernel of the version 2 may be extended using optional thematic modules. These modules concern: vegetation monitoring, reporting (in coherence with current French regulatory requirements, riverbanks, riverbed... Main functionnalities perfomed by SIRS Digues V1 and V2 are : data structuring and centralisation, quick access to relevant data, reporting and mapping, etc. SIRS Digues 2.0 updates and improves already existing functionalities of the first version. SIRS Digues V2 relies on an documentoriented NoSQL database, CouchDB, and on geospatial libraries, Geotoolkit and Apache-SIS. SIRS Digues V2 was released with a copyleft license. Copyrights belong to the French levees managers’ society, “France Digues”, which acts as a cooperative. Members put their heads together in order to gather their financial capacities and fund software development. France Digues has got the technical and thematic expertise and supply various services to the members. This business model aims to ensure accessibility, durability and adaptability of the software.

  20. Soluble Immune Response Suppressor (SIRS): Reassessing the immunosuppressant potential of an elusive peptide.

    Webb, David R

    2016-10-01

    A previously studied immunosuppressive cytokine, Soluble Immune Response Suppressor (SIRS), may have relevance to current studies of immune suppression in a variety of human disease states. Despite extensive efforts using experimental models, mainly in mice, much remains to be discovered as to how autoimmune cells in mice and humans escape normal regulation and, conversely, how tumor cells evade evoking an immune response. It is the contention of this commentary that the literature pre-2000 contain results that might inform current studies. The broadly immunosuppressive protein, SIRS, was studied extensively from the 1970s to 1990s and culminated in the determination of the n-terminal 21mer sequence of this 15kDa protein which had high homology to the short neurotoxins from sea snakes, that are canonical members of the three finger neurotoxin superfamily (3FTx). It was not until 2007 that the prophylactic administration of the synthetic N-terminal peptide of the SIRS 21mer, identical to the published sequence, was reported to inhibit or delay the development of two autoimmune diseases in mice: experimental allergic encephalomyelitis (EAE) and type I diabetes (T1D). These findings were consistent with other studies of the 3FTx superfamily as important probes in the study of mammalian pharmacology. It is the perspective of this commentary that SIRS, SIRS peptide and the anti-peptide mAb, represent useful, pharmacologically-active probes for the study of the immune response as well as in the potential treatment of autoimmune, inflammatory diseases and cancer.

  1. Treatment of post-cardiopulmonary bypass SIRS by hemoadsorption: a case series.

    The use of cardiopulmonary bypass (CPB) in cardiothoracic surgery results in a well-known activation of the immunologic response. In some cases, however, this triggered immunologic response may be excessive, leading to a severe systemic inflammatory response syndrome (SIRS) and induced organ dysfunction. For example, patients frequently develop hemodynamic instability with hypotension and low systemic vascular resistance. To date, different therapeutic approaches, such as steroids, have been tried to control this maladaptive postoperative SIRS response, yet definitive proof of clinical efficacy is missing. A new cytokine adsorber device (CytoSorb; CytoSorbents) may be a useful approach to control hyperinflammatory systemic reactions by reducing a broad range of proinflammatory cytokines and other inflammatory mediators. This may, in turn, help to reestablish a physiologic immune response and help to restore deranged clinical parameters in these patients. In this retrospective case series study, we describe 16 cardiac surgery patients following prolonged CPB with post-CPB SIRS and subsequent acute kidney injury, who were then treated with hemoadsorption using CytoSorb in combination with continuous renal replacement therapy (CRRT). Treatment of patients with CytoSorb who presented with severe post-CPB SIRS resulted in a reduction of elevated cytokine levels, which was associated with a clear stabilization of deranged hemodynamic, metabolic, and organ function parameters. Treatment was well tolerated and safe, with no device-related adverse events occurring. CytoSorb therapy combined with CRRT is a potentially promising new treatment approach to achieve hemodynamic stability, cytokine reduction, and improved organ function in cardiac surgery patients who develop post-CPB SIRS.

  2. A Dirty Hero’s Fight for Clean Energy: Satire, Allegory, and Risk Narrative in Ian McEwan’s Solar

    2012-01-01

    Full Text Available In contrast to most other fictional texts treating ecological crisis, Ian McEwan's Solar (2010, celebrated as "the book on climate change," does not develop an apocalyptic scenario culminating in a collective catastrophe. Instead, while on the level of discourse mocking today's rhetoric of risk, it stages the disastrous personal risk management of its protagonist by use of satire. Whereas traditionally literary descriptions of natural disasters often function as allegories for social disasters, McEwan reverses this model by employing a private disaster to foreshadow a possible global catastrophe. The story can thus be read as satiric-allegorical risk narrative. On the one hand this concept is responsible for basic misunderstandings, on the other hand for praise as "the first climate-novel by an author of world-class quality." This essay first analyzes the protagonist's explicit reckoning with risk discourse, then unveils the satirical and allegorical dimensions of his own risk management to demonstrate the novel's aesthetic originality and the potential of this new form of eco-fiction.

    Sedimentological and geochemical investigation of sediment cores collected in the deep (>400 m) central basin of Prince William Sound, along with geochemical fingerprinting of sediment source areas, are used to identify earthquake-generated sediment gravity flows. Prince William Sound receives sediment from two distinct sources: from offshore (primarily Copper River) through Hinchinbrook Inlet, and from sources within the Sound (primarily Columbia Glacier). These sources are found to have diagnostic elemental ratios indicative of provenance; Copper River Basin sediments were significantly higher in Sr/Pb and Cu/Pb, whereas Prince William Sound sediments were significantly higher in K/Ca and Rb/Sr. Within the past century, sediment gravity flows deposited within the deep central channel of Prince William Sound have robust geochemical (provenance) signatures that can be correlated with known moderate to large earthquakes in the region. Given the thick Holocene sequence in the Sound ( 200 m) and correspondingly high sedimentation rates (>1 cm year-1), this relationship suggests that sediments within the central basin of Prince William Sound may contain an extraordinary high-resolution record of paleoseismicity in the region.

    Stellar astrophysicist William Kenneth Rose died near his home in Potomac, Maryland, on September 30, 2010, after an extended illness. Rose was the son of pharmacist Kenneth William Rose and Shirley Near Rose and was born in Ossining, New York, on August 10, 1935. He received an AB from Columbia College in 1957 and a PhD in physics from Columbia University in 1963, with a thesis on "measurements of linear polarization in discrete radio sources using a 9.4 cm maser," under the direction of Charles H. Townes. Rose played a major role in designing and constructing the maser and used it at a radio telescope at Maryland Point that belonged to the Naval Research Lab. He observed Jupiter and Saturn and a number of extra-solar-system sources, and also diffuse centimeter emission (see appendix). The thesis was not published in an archival journal, but can be found under Library of Congress code QB 475.R67. While in graduate School, Bill married Sheila Tuchman, whose primary scientific interests were biological. None of their three children chose to be scientists, but two are CPAs. Bill moved successfully through the academic hurdles) from a research position at Princeton (1963-67), where a collaboration with Nick Woolf and Martin Schwarzchild on the infrared spectra of giant stars became one of his most-cited papers, to assistant and associate professorships at MIT (1967-71), and then associate and full professorships at the University of Maryland (1971 to retirement in 2005). His most innovative work was probably that on nova explosions arising from degenerate ignition of hydrogen accreted on white dwarfs in close binary systems, published in 1968. The same idea occurred to others at about the same time, and Bill did not, perhaps, get quite his fair share of the credit. I first met Sheila and Bill in summer 1969 at the Stony Brook summer school on stellar evolution (not published until 1972). He lectured on the nature of nova explosions and on nuclear burning in thin

  5. Fkh1 and Fkh2 associate with Sir2 to control CLB2 transcription under normal and oxidative stress conditions

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available The Forkhead box family of transcription factors is evolutionary conserved from yeast to higher eukaryotes and its members are involved in many physiological processes including metabolism, DNA repair, cell cycle, stress resistance, apoptosis and aging. In budding yeast, four Forkhead transcription factors were identified, namely Fkh1, Fkh2, Fhl1, and Hcm1, which are implicated in chromatin silencing, cell cycle regulation and stress response. These factors impinge transcriptional regulation during cell cycle progression, and histone deacetylases play an essential role in this process, e.g. the nuclear localisation of Hcm1 depends on Sir2 activity, whereas Sin3/Rpd3 silence cell cycle specific gene transcription in G2/M phase. However, a direct involvement of Sir2 in Fkh1/Fkh2-dependent regulation of target genes is at present unknown. Here, we show that Fkh1 and Fkh2 associate with Sir2 in G1 and M phase, and that Fkh1/Fkh2-mediated activation of reporter genes is antagonized by Sir2. We further report that Sir2 overexpression strongly affects cell growth in an Fkh1/Fkh2-dependent manner. In addition, Sir2 regulates the expression of the mitotic cyclin Clb2 through Fkh1/Fkh2-mediated binding to the CLB2 promoter in G1 and M phase. We finally demonstrate that Sir2 is also enriched at the CLB2 promoter under stress conditions, and that the nuclear localization of Sir2 is dependent on Fkh1 and Fkh2. Taken together, our results show a functional interplay between Fkh1/Fkh2 and Sir2 suggesting a novel mechanism of cell cycle repression. Thus, in budding yeast, not only the regulation of G2/M gene expression but also the protective response against stress could be directly coordinated by Fkh1 and Fkh2.

    In May 2008, the Supreme Court addressed whether the government can regulate the ownership and distribution of virtual child pornography. U.S. v. Williams marked the first time the Court directly addressed the concept of pandering virtual child pornography. This article examines the Court's decision in U.S. v.

Restricting the sale of both real and virtual child pornography is essential to combat the various problems surrounding its existence, which include policing its creation and distribution on the Internet as well as the connection between child pornography and subsequent sexual offenses against children.

  8. Antonio Gramsci en los estudios culturales de Raymond Williams

    Full Text Available Este artículo intenta poner de manifiesto la deuda de los estudios culturales de Raymond Williams con la obra del filólogo-político Antonio Gramsci. En concreto, intenta demostrar cómo Williams encuentra en Gramsci el método adecuado para analizar las manifestaciones artístico-culturales en relación con la lucha por la hegemonía y cómo es a partir de Gramsci que pueden ser entendidos los desarrollos posteriores de los estudios culturales, desde Williams hasta Stuart Hall. Mediante el análisis de la obra de Williams y a partir del conocimiento del pensamiento de Gramsci hemos sido capaces de encontrar la herencia de Gramsci como elemento decisivo en la fundación de los estudios culturales tal y como nacen de manera multidisciplinar a partir de los pioneros trabajos en este campo de Raymond Williams. Asimismo podemos llegar a la conclusión de que tanto los Quaderni de Gramsci como los denominados “escritos juveniles” supusieron para Williams el descubrimiento no sólo del método adecuado para analizar las manifestaciones artístico-culturales en relación con la hegemonía, sino que además Gramsci aportó un número importante de problemáticas y palabras clave sobre las que han sido fundados posteriormente los estudios culturales en las distintas universidades de manera global.

  9. Obituary: William L. Kraushaar, 1920-2008

    Clark, George W.

    2009-01-01

    Professor William L. Kraushaar, a former MIT physics professor and a pioneer in the field of high-energy astronomy, died 21 March 2008 of complications from Parkinson's disease. He was 87. Kraushaar received his bachelor's degree from Lafayette College in 1942. During World War II he worked at the National Bureau of Standards on projects that included development of the proximity fuse for artillery shells. After the war he earned his doctorate at Cornell University. In 1949 Kraushaar was appointed research associate at MIT, where he made the first measurements of the mean life of the pi meson at the MIT electron synchrotron. Over the next fifteen years he rose through the faculty ranks, becoming a full professor before leaving MIT for the University of Wisconsin at Madison in 1965. In 1957 Kraushaar began a decade-long effort to map the sky in the "light" of cosmic gamma rays. Their detection promised to open new ways to investigate high-energy processes in the universe. Initial balloon-borne experiments failed due to background gamma rays generated in the residual atmosphere above the highest attainable altitudes. In 1958, Kraushaar seized a new opportunity for experiments above the atmosphere. Working with Professor George Clark, he directed the development in the MIT Laboratory for Nuclear Science of a gamma-ray detector for a satellite experiment that was launched in April 1961 as Explorer 11. It registered 31 events with the electronic signatures of cosmic gamma rays with energies greater than 50 MeV. Kraushaar then initiated a second and more refined experiment to be carried on OSO 3. In this project Kraushaar and Clark were joined by Gordon Garmire, a former student of Kraushaar. The OSO 3 experiment, launched in March of 1967, registered 621 cosmic gamma-ray events. It yielded the first all-sky map of high-energy cosmic gamma rays showing a concentration of gamma rays from directions in the Milky Way where gamma-ray producing interactions of charged cosmic

    The determination of the geographical origin of food products is relevant to comply with the legal regulations of traceability, to avoid food fraud, and to guarantee food quality and safety to the consumers. For these reasons, stable isotope ratio (SIR) analysis using an isotope ratio mass spectrometry (IRMS) instrument is one of the most useful techniques for evaluating food traceability and authenticity. The present study was aimed to determine, for the first time, the geographical origin for all commercial fish species belonging to the Merlucciidae family using SIR analysis of carbon (δ 13 C) and nitrogen (δ 15 N). The specific results enabled their clear classification according to the FAO (Food and Agriculture Organization of the United Nations) fishing areas, latitude, and geographical origin in the following six different clusters: European, North African, South African, North American, South American, and Australian hake species.

  12. Compact Diplexer with High Isolation and Wide Stopband Based on SIRs

    2017-05-01

    A compact microstrip diplexer with a high isolation and improved out-of-band performance is proposed in this paper. The proposed diplexer is based on cascaded-quadruplet (CQ) bandpass filters (BPFs), which is composed of λ/4 stepped-impedance resonators (SIRs). By employing the edge and quasi-lumped coupling topology, a compact diplexer with improved passband selectivity can be achieved. Meanwhile, by appropriately adjusting the impedance and electric length ratios of SIRs, the stopband can be extended to 20 GHz with a rejection level of 10 dB, which is 12.7 times of the fundamental frequency. The predicted results on S parameters are compared with the measured ones and good agreement is achieved.

  13. Mutations that Allow SIR2 Orthologs to Function in a NAD+-Depleted Environment

    Directory of Open Access Journals (Sweden)

    Caitlin R. Ondracek

    2017-03-01

    Full Text Available Sirtuin enzymes depend on NAD+ to catalyze protein deacetylation. Therefore, the lowering of NAD+ during aging leads to decreased sirtuin activity and may speed up aging processes in laboratory animals and humans. In this study, we used a genetic screen to identify two mutations in the catalytic domain of yeast Sir2 that allow the enzyme to function in an NAD+-depleted environment. These mutant enzymes give rise to a significant increase of yeast replicative lifespan and increase deacetylation by the Sir2 ortholog, SIRT1, in mammalian cells. Our data suggest that these mutations increase the stability of the conserved catalytic sirtuin domain, thereby increasing the catalytic efficiency of the mutant enzymes. Our approach to identifying sirtuin mutants that permit function in NAD+-limited environments may inform the design of small molecules that can maintain sirtuin activity in aging organisms.

    Full Text Available This paper considers an SIRS model with nonlinear incidence rate and treatment. It is assumed that susceptible and infectious individuals have constant immigration rates. We investigate the existence of equilibrium and prove the global asymptotical stable results of the endemic equilibrium. We then obtained that the model undergoes a Hopf bifurcation and existences a limit cycle. Some numerical simulations are given to illustrate the analytical results.

  17. Milestones in plant sulfur research on sulfur-induced-resistance (SIR in Europe

    Full Text Available Until the 1970´s of the last century sulfur (S was mainly regarded as a pollutant being the main contributor of acid rain, causing forest dieback in central Europe. When Clean Air Acts came into force at the start of the 1980´s SO2 contaminations in the air were consequently reduced within the next years. S changed from an unwanted pollutant into a lacking plant nutrient in agriculture since agricultural fields were no longer fertilized indirectly by industrial pollution. S deficiency was first noticed in Brassica crops that display an especially high S demand because of its content of S-containing secondary metabolites, the glucosinolates. In Scotland, where S depositions decreased even faster than in continental Europe, an increasing disease incidence with Pyrenopeziza brassicae was observed in oilseed rape in the beginning 1990´s and the concept of sulfur-induced-resistance (SIR was developed after a relationship between the S status and the disease incidence was uncovered. Since then a lot of research was carried out to unravel the background of SIR in the metabolism of agricultural crops and to identify metabolites, enzymes and reactions, which are potentially activated by the S metabolism to combat fungal pathogens. The S status of the crop is affecting many different plant features such as color and scent of flowers, pigments in leaves, metabolite concentrations and the release of gaseous S compounds which are directly influencing the desirability of a crop for a variety of different organisms from microorganisms, over insects and slugs to the point of grazing animals.The present paper is an attempt to sum up the knowledge about the effect of the S nutritional status of agricultural crops on parameters that are directly related to their health status and by this to SIR. Milestones in SIR research are compiled, open questions are addressed and future projections were developed.

    The emergence of Zika and Ebola demonstrates the importance of understanding the role of sexual transmission in the spread of diseases with a primarily non-sexual transmission route. In this paper, we develop low-dimensional models for how an SIR disease will spread if it transmits through a sexual contact network and some other transmission mechanism, such as direct contact or vectors. We show that the models derived accurately predict the dynamics of simulations in the large population limi...

    In this paper, we investigate two stochastic SIR epidemic models with higher order perturbation. For the nonautonomous periodic case of the model, by using Has'minskii's theory of periodic solution, we show that the system has at least one nontrivial positive T-periodic solution. For the system disturbed by both the white noise and telephone noise, we establish sufficient conditions for positive recurrence and the existence of ergodic stationary distribution of the positive solution.

    This paper is concerned with traveling waves of a delayed SIR model with nonlocal dispersal and a general nonlinear incidence. The existence and nonexistence of traveling waves of the system are established respectively by Schauder's fixed point theorem and two-sided Laplace transform. It is also shown that the spread speed c is influenced by the dispersal rate of the infected individuals and the delay τ.

    A class of SIR epidemic model with generalized nonlinear incidence rate is presented in this paper. Temporary immunity and stochastic perturbation are also considered. The existence and uniqueness of the global positive solution is achieved. Sufficient conditions guaranteeing the extinction and persistence of the epidemic disease are established. Moreover, the threshold behavior is discussed, and the threshold value R0 is obtained. We show that if R0 1, then the system remains permanent in the mean.

  2. The Sex Differences of Morphology and Immunology of SIRS of Newborn Wistar Rats.

    2014-01-01

    The sex differences of infection and inflammatory diseases particularly appear at reproductive age and depend on the sex hormone level, varied between male and female. There are a few sets of data about the sex differences of infection and inflammatory diseases course, including systemic inflammatory response syndrome (SIRS) and sepsis, of newborns. The aim of our research was the estimation of morphological and immunological manifestation of SIRS of the newborn Wistar rats. Investigations were carried out on male and female two-day-old Wistar rats (10-12 g). SIRS was modeled by intraperitoneal injection of LPS (E. coli, O26: B6 strain, Sigma) in high dose-15 mg/kg. We did not find out any sex differences of the liver lesions severity between newborn males and females after LPS injection. The levels of endotoxin and estradiol in the serum, as the number of neutrophils in the intra-alveolar septa of the lungs, were higher in males than females with SIRS. Production of IL-2 and TNF-α by the spleen cells of males was higher than that in control group that reflects polarization predominantly on the Th1-type immune response. The secretion of IL-2, TNF-α, and IFN-γ by ConA activated spleen cells of females decreased that reflects the suppression of Th1-type immune response. We suppose that the LPS administration in the high dose causes the multidirectional reaction of the immune system of neonatal males and females Wistar rats.

    This retrospective, single-center study was designed to distinguish severe diabetic foot infection (DFI) from moderate DFI based on the presence or absence of systemic inflammatory response syndrome (SIRS). The database of a single academic foot and ankle program was reviewed and 119 patients were identified. Severe DFI was defined as local infection associated with manifestation of two or more objective findings of systemic toxicity using SIRS criteria. Patients with severe DFI experienced a 2.55-fold higher risk of any amputation (95% CI 1.21-5.36) and a 7.12-fold higher risk of major amputation (1.83-41.05) than patients with moderate DFI. The risk of minor amputations was not significantly different between the two groups (odds ratio 1.02 [95% CI 0.51-2.28]). The odds of having a severe DFI was 7.82 times higher in patients who presented with gangrene (2.03-44.81) and five times higher in patients who reported symptoms of anorexia, chills, nausea, or vomiting (2.22-11.25). The mean hospital length of stay for patients with severe DFI was ∼4 days longer than for patients with moderate DFI, and this difference was statistically significant. SIRS is valid in distinguishing severe from moderate DFI in hospitalized patients. Patients with severe DFI, as by manifesting two or more signs of systemic inflammation or toxicity, had higher rates of major amputation and longer hospital stays and required more surgery and more subsequent admissions than patients who did not manifest SIRS.

    The development of a vaccine conferring long-lasting immunity remains a challenge against visceral leishmaniasis (VL). Immunoproteomic characterization of Leishmania donovani proteins led to the identification of a novel protein NAD+-dependent Silent Information regulatory-2 (SIR2 family or sirtuin) protein (LdSir2RP) as one of the potent immunostimulatory proteins. Proteins of the SIR2 family are characterized by a conserved catalytic domain that exerts unique NAD-dependent deacetylase activity. In the present study, an immunobiochemical characterization of LdSir2RP and further evaluation of its immunogenicity and prophylactic potential was done to assess for its possible involvement as a vaccine candidate against leishmaniasis. LdSir2RP was successfully cloned, expressed and purified. The gene was present as a monomeric protein of ~45 kDa and further established by the crosslinking experiment. rLdSir2RP shown cytosolic localization in L. donovani and demonstrating NAD+-dependent deacetylase activity. Bioinformatic analysis also confirmed that LdSir2RP protein has NAD binding domain. The rLdSir2RP was further assessed for its cellular response by lymphoproliferative assay and cytokine ELISA in cured Leishmania patients and hamsters (Mesocricetus auratus) in comparison to soluble Leishmania antigen and it was observed to stimulate the production of IFN-γ, IL-12 and TNF-α significantly but not the IL-4 and IL-10. The naïve hamsters when vaccinated with rLdSir2RP alongwith BCG resisted the L. donovani challenge to the tune of ~75% and generated strong IL-12 and IFN-γ mediated Th1 type immune response thereof. The efficacy was further supported by remarkable increase in IgG2 antibody level which is indicative of Th1 type of protective response. Further, with a possible implication in vaccine design against VL, identification of potential T-cell epitopes of rLdSir2RP was done using computational approach. The immunobiochemical characterization strongly suggest the

    Nicotinamide (NAM), a form of vitamin B 3 , is a byproduct and noncompetitive inhibitor of the deacetylation reaction catalyzed by Sirtuins. These represent a family of evolutionarily conserved NAD + -dependent deacetylases that are well-known critical regulators of metabolism and aging and whose founding member is Sir2 of Saccharomyces cerevisiae. Here, we investigated the effects of NAM supplementation in the context of yeast chronological aging, the established model for studying aging of postmitotic quiescent mammalian cells. Our data show that NAM supplementation at the diauxic shift results in a phenocopy of chronologically aging sir2Δ cells. In fact, NAM-supplemented cells display the same chronological lifespan extension both in expired medium and extreme Calorie Restriction. Furthermore, NAM allows the cells to push their metabolism toward the same outcomes of sir2Δ cells by elevating the level of the acetylated Pck1. Both these cells have the same metabolic changes that concern not only anabolic pathways such as an increased gluconeogenesis but also respiratory activity in terms both of respiratory rate and state of respiration. In particular, they have a higher respiratory reserve capacity and a lower non-phosphorylating respiration that in concert with a low burden of superoxide anions can affect positively chronological aging.

    The use of computed tomography (CT) in acute pancreatitis (AP) continues to increase in parallel with the increasing use of diagnostic imaging in clinical medicine. To determine the factors associated with obtaining >1 CT scan in acute interstitial pancreatitis (AIP). Demographic and clinical data of all adult patients admitted between 1/2010 and 1/2015 with AP (AP) were evaluated. Only patients with a CT severity index (CTSI) ≤ 3 on a CT obtained within 48 h of presentation were included. A total of 229 patients were included, of whom 206 (90%) had a single CT and 23 (10%) had >1 CT during the first week of hospitalization. Patients undergoing >1 CT had significantly higher rates of acute fluid collection (AFC), persistent SIRS, opioid use ≥4 days, and persistent organ failure compared to those undergoing 1 CT (p SIRS (OR = 3.6, 95% CI 1.4-9.6, p = .01) and an AFC on initial CT (OR = 3.5, 95% CI 1.4-9, p = .009) were independently associated with obtaining >1 CT. An AFC on initial CT and persistent SIRS are associated with increased CT imaging in AIP patients. However, these additional CT scans did not change clinical management.

    This paper describes and demonstrates a method for relative risk estimation which is based on the stochastic SIR-SI vector-borne infectious disease transmission model specifically for Dengue and Chikungunya diseases in Malaysia. Firstly, the common compartmental model for vector-borne infectious disease transmission called the SIR-SI model (susceptible-infective-recovered for human populations; susceptible-infective for vector populations) is presented. This is followed by the explanations on the stochastic SIR-SI model which involve the Bayesian description. This stochastic model then is used in the relative risk formulation in order to obtain the posterior relative risk estimation. Then, this relative estimation model is demonstrated using Dengue and Chikungunya data of Malaysia. The viruses of these diseases are transmitted by the same type of female vector mosquito named Aedes Aegypti and Aedes Albopictus. Finally, the findings of the analysis of relative risk estimation for both Dengue and Chikungunya diseases are presented, compared and displayed in graphs and maps. The distribution from risk maps show the high and low risk area of Dengue and Chikungunya diseases occurrence. This map can be used as a tool for the prevention and control strategies for both diseases

    Systemic inflammatory response syndrome (SIRS) is associated with an increased risk of hepatic encephalopathy, renal failure, and poor outcome in patients with cirrhosis; however, there is a paucity of studies on this entity for severe alcoholic hepatitis (SAH). To evaluate SIRS at baseline as a predictor of development of acute kidney injury (AKI) and mortality in patients with SAH. Consecutive in-patients with SAH (discriminant function ≥ 32) without AKI at baseline were followed up for the development and progression of AKI (AKIN criteria). Of the 365 patients (mean age 45.5 ± 9.5, 356 males), SIRS at baseline was present in 236 (64.6%). AKI developed in 122 (33.4%), of which 50 (40.9%) had progression of AKI. SIRS was associated with bacterial infections in 96 (40.6%) and in 140 (59.3%) occurred in the absence of proven infection microbiologically. The presence of SIRS predicted both AKI development (p SIRS (p = 0.001). High MELD score (p = 0.002, HR 1.1, 95% CI 1.02-1.09), in-hospital progression of AKI (p = 0.04, HR 1.54, 95% CI 1.003-2.38), and SIRS (p = 0.004, HR 1.98, 95% CI 1.25-3.1) were significant predictors of 90-day mortality (model 1), while high MELD score (p SIRS at admission predicts both the development of AKI and 90-day mortality in patients with SAH. This could definitely have a therapeutic and prognostic implication.

    2015-04-01

    The myeloperoxidase index (MPXI) is elevated in infection. We ascertained whether MPXI might be useful in differentiation of sepsis versus non-infectious systemic inflammatory response syndrome (SIRS) in emergency department (ED). After exclusion of patients with an age of SIRS (sepsis: 224, 50.3%; and non-infectious SIRS: 220, 49.7%) diagnosed and treated at the ED of The Wonju Severance Christian Hospital from May 2012 to June 2012 were retrospectively reviewed. Median MPXI was higher in sepsis versus non-infectious SIRS (0.1 (IQR: -3.1 to 2.5) vs -1.2 (-4.1 to 1.6), respectively, p=0.020). Median white cell count, neutrophil percentage, C reactive protein level and δ neutrophil index were also higher. However, MPXI resulted as not statistically useful for differential diagnostic parameter in analysis. MPXI is higher in sepsis than in non-infectious SIRS. However, there is currently no evidence that the MPXI adds any additional benefit to differentiate sepsis from non-infectious SIRS in the ED. Therefore, further study will be needed.

  16. Seasonal distribution of Dall's porpoise in Prince William Sound, Alaska

    Science.gov (United States)

    Moran, John R.; O'Dell, Matthew B.; Arimitsu, Mayumi L.; Straley, Janice M.; Dickson, Danielle M. S.

    2018-01-01

    Dall's porpoise, Phocoenoides dalli, are a conspicuous predator in the Prince William Sound ecosystem, yet there has been little effort directed towards monitoring this species since the 1980s, prior to the Exxon Valdez oil spill. We used vessel-based surveys to examine the seasonal distribution of Dall's porpoise in the waters of Prince William Sound during eight years from 2007 to 2015. Over the course of 168 days and 15,653 km of survey effort, 921 Dall's porpoise were encountered in 210 groups. We estimate an encounter rate of 0.061 porpoise/km traveled or 1 porpoise encountered for every 16.5 km traveled. Dall's porpoise were found throughout the year in Prince William Sound, and used a wide range of habitats, including those not considered typical of the species, such as bays, shallow water, and nearshore waters. Dall's porpoise seasonally shifted their center of distribution from the western passages in fall to the bays of the eastern Sound in winter and spring. Dall's porpoises were widely dispersed throughout the Sound in summer. We identified potential Dall's porpoise habitat (depth, slope, and distance from shore) within Prince William Sound using generalized additive models (GAM). Dall's porpoise were found in deeper water during summer and in shallowest water during spring. We propose that their use of novel habitats is a function of reduced predation risk associated with the decline of their main predator, killer whales (Orcinus orca), following the Exxon Valdez oil spill, and the presence of overwintering and spawning Pacific herring (Clupea pallasii). While the size of the Dall's porpoise population within Prince William Sound remains unknown, our encounter rates were lower than those reported in the 1970s. Their high metabolic rate and ubiquitous presence makes them one of the more important, yet understudied, forage fish predators in the region.

    Clinical Validation of the Caregiver-Child Socioemotional and Relationship Rating Scale (SIRS) for Child Behavior in a Preschool-Age Sample The description of child behavior in mother-child-interaction is important in early detection and treatment of psychiatric disorders in preschool children. The Caregiver-Child Socioemotional and Relationship Rating Scale (SIRS) may serve this diagnostic purpose. We aim to examine interrater-reliability of SIRS and concurrent, convergent, and discriminant validity to maternal behavior by Play-PAB, and a measure of mother-child-relationsship by Parent-Infant-Global-Assessment-Scale (PIRGAS). Five raters assessed 47 ten-minute video sequences of parent-child-interaction recorded at the Family Day Hospital for Preschool Children with SIRS, Play-PAB, and PIRGAS. We report psychometric properties of SIRS, and present the association with Play-PAB and PIRGAS. SIRS shows a satisfying interrater-reliability for all items. Positive child behavior e. g. the SIRS' "child responsiveness" shows negative correlation to Play-PAB-scales' parental "hostility" and "intrusiveness", but independence of parental "involvement", "positive emotionality", and "discipline". Child and parental behavior show expected associations with the global relationship measure PIRGAS. The assessment of child behavior in parent-child-interaction with SIRS can be quickly learned and reliably applied without extensive training. SIRS shows meaningful relations to parental behavior and a clinical global measure of the caregiver-child-relationship. We recommend SIRS for clinical diagnostics to describe child behavior in mother-child-interaction.

  19. Antonio Gramsci en los estudios culturales de Raymond Williams

    Directory of Open Access Journals (Sweden)

    Álvaro Alonso Trigueros

    2014-05-01

    Full Text Available Este artículo intenta poner de manifiesto la deuda de los estudios culturales de Raymond Williams con la obra del filólogo-político Antonio Gramsci. En concreto, intenta demostrar cómo Williams encuentra en Gramsci el método adecuado para analizar las manifestaciones artístico-culturales en relación con la lucha por la hegemonía y cómo es a partir de Gramsci que pueden ser entendidos los desarrollos posteriores de los estudios culturales, desde Williams hasta Stuart Hall. Mediante el análisis de la obra de Williams y a partir del conocimiento del pensamiento de Gramsci hemos sido capaces de encontrar la herencia de Gramsci como elemento decisivo en la fundación de los estudios culturales tal y como nacen de manera multidisciplinar a partir de los pioneros trabajos en este campo de Raymond Williams. Asimismo podemos llegar a la conclusión de que tanto los Quaderni de Gramsci como los denominados “escritos juveniles” supusieron para Williams el descubrimiento no sólo del método adecuado para analizar las manifestaciones artístico-culturales en relación con la hegemonía, sino que además Gramsci aportó un número importante de problemáticas y palabras clave sobre las que han sido fundados posteriormente los estudios culturales en las distintas universidades de manera global.

  20. Mitochondrial DNA is Released in Urine of SIRS Patients With Acute Kidney Injury and Correlates With Severity of Renal Dysfunction.

    Systemic inflammatory response syndrome (SIRS) is characterized by the activation of the innate immune system resulting in stimulation of inflammatory responses, coagulation, and platelet activation that may contribute to complication such as the development of acute kidney injury (AKI). AKI importantly worsens the outcome of SIRS, implying the existence of a detrimental cross talk via systemic messages. Mitochondria are a source of damage-associated molecular patterns (DAMPs) and are thought to form a molecular link between tissue injury and stimulation of innate immunity. The role of mitochondrial DNA (mtDNA) in the cross talk between the onset of SIRS and subsequent development of AKI is unknown. Hence, we performed a case control study in critically ill patients with SIRS diagnosed with or without AKI, in which we determined mtDNA levels in plasma and urine, and correlated these to markers of renal impairment, inflammation, coagulation, and platelet activation. In addition, we exposed mice, primary renal tubular epithelial cells (TECs), and platelets to mtDNA or purified mitochondrial ligands, and measured their response to elucidate underlying pathophysiological mechanisms. Our data reveal that increased systemic mtDNA levels in SIRS patients do not correlate with systemic inflammation and renal disease activity. Moreover, AKI does not have an additional effect on circulating mtDNA levels. In contrast, we found that urinary mtDNA levels correlate with an elevated albumin creatinine ratio (ACR) as well as with increased urinary markers of inflammation, coagulation, and platelet activation. Both renal TECs and platelets respond to mtDNA and mtDNA ligands, leading to increased expression of, respectively, inflammatory cytokines and P-selectin. Moreover, activation of platelets results in mtDNA release. Together, these data suggest that circulating mtDNA is probably not important in the detrimental cross talk between SIRS and AKI, whereas renal mtDNA accumulation

    Hepatic encephalopathy (HE) is a complication associated with worst prognosis in decompensated liver cirrhosis (LC) patients. Previous studies have identified prognostic factors for HE, and recent studies reported an association between systemic inflammatory response syndrome (SIRS) and liver disease. This study aimed to identify prognostic factors for 30-day mortality in alcoholic LC patients with HE who visited the emergency department (ED).This was a retrospective study of alcoholic LC patients with HE from January 1, 2010, to April 30, 2015. The baseline characteristics, complications of portal hypertension, laboratory values, Child-Pugh class, Model for End-stage Liver Disease (MELD) score, chronic liver failure-sequential organ failure assessment (CLIF-SOFA) score, and SIRS criteria were assessed. The presence of 2 or more SIRS criteria was considered SIRS. The primary outcomes were 30-day mortality and prognostic factors for patients with HE visiting the ED.In total, 105 patients who met the inclusion criteria were analyzed. Overall, the 30-day mortality rate was 6.7% (7 patients).Significant variables were hepatorenal syndrome, international normalized ratio, white blood cell count, total bilirubin level, MELD score CLIF-SOFA score, and SIRS in univariate analysis. CLIF-SOFA score and SIRS were the significant factors in the multivariate analysis (hazard ratio 5.56, 15.98; 95% confidence interval 1.18-26.18, 1.58-161.37; P = 0.03, P = 0.02). The mortality rates differed according to the CLIF-SOFA score (P SIRS in alcoholic LC patients with HE visiting the ED are independent predictors of 30-day mortality.

    We carefully compute the gluon propagator in the background of a non-Abelian Weizsaecker-Williams field. This background field is generated by the valence quarks in very large nuclei. We find contact terms in the small fluctuation equations of motion which induce corrections to a previously incorrect result for the gluon propagator in such a background field. The well-known problem of the Hermiticity of certain operators in the light cone gauge is resolved for the Weizsaecker-Williams background field. This is achieved by working in a gauge where singular terms in the equations of motion are absent and then gauge transforming the small fluctuation fields to the light cone gauge

    Social scientists have mostly taken it for granted that William Foote Whyte's sociological classic Street Corner Society (SCS, 1943) belongs to the Chicago school of sociology's research tradition or that it is a relatively independent study which cannot be placed in any specific research tradition. Social science research has usually overlooked the fact that William Foote Whyte was educated in social anthropology at Harvard University, and was mainly influenced by Conrad M. Arensberg and W. Lloyd Warner. What I want to show, based on archival research, is that SCS cannot easily be said either to belong to the Chicago school's urban sociology or to be an independent study in departmental and idea-historical terms. Instead, the work should be seen as part of A. R. Radcliffe-Brown's and W. Lloyd Warner's comparative research projects in social anthropology. © 2013 Wiley Periodicals, Inc.

  4. Ischemic Stroke in Williams-Beuren Syndrome: A Case Report

    2009-04-01

    Full Text Available A 15-year-old girl was admitted because of an acute onset of facial palsy and right hemiparesis. The patient had a history of moderate mental retardation and developmental delay. On admission, her vital signs were stable, except for high blood pressure. Magnetic resonance imaging demonstrated an infarct involving the left internal capsule and putamen. Because of the patient's young age, an extensive stroke survey was performed. Williams-Beuren syndrome was finally confirmed by fluorescent in situ hybridization. Compared with the previously reported cases, no evidence of cerebral arterial stenosis or cardiac abnormalities was found by noninvasive imaging techniques. Because Williams-Beuren syndrome is a complex, multiple congenital anomaly syndrome with prominent cardiovascular features, regular assessment and antihypertensive treatment are necessary to minimize the lifelong cardiovascular risk in patients with this syndrome.

    The objective of this study is to investigate the influences of percutaneous nephrolithotomy (PNL) and open surgery nephrolithotomy on the systemic stress response, SIRS and renal function. Forty patients with kidney calculi were enrolled in the study. Twenty cases were randomized to the PNL group and the other twenty cases to the open surgery group. Levels of C-reactive protein (CRP), interleukin-6(IL-6), β(2)-microglobulin (β(2)-MG), respiration rate, heart rate, body temperature and white blood cell counts were examined. CRP and IL-6 were measured in all patients pre-operatively and on post-operative days 1, 3 and 6, respectively. There was significant difference in their pre- and post-operation levels (P PNL group and 12 cases in open surgery group; there was significant difference between the two groups (P 0.05). Urine β(2)-MG levels were also measured. There was significant difference between pre- and the first day post-PNL (P PNL (P > 0.05). There was significant difference between pre- and first and third day post-open surgery (P 0.05). There was significant difference between two groups at the first, third and sixth days (P PNL group and open surgery group to some extent. The degree of stress response of PNL is lower than that of open surgery, proving the advantages of PNL with reference to serum immunology. There were cases in both the groups with SIRS, but the degree of SIRS in PNL group was lesser than the other group. Both the groups have no obvious effect on glomerular filtration function after operation and have effect on renal tubular reabsorption in the early stage after operation; but the recovery of the PNL group is faster than the open surgery group. It is thus shown that PNL is much safer and more feasible and has lesser effect on renal function.

  6. Systemic inflammatory response syndrome (SIRS): where did it come from and is it still relevant today?

    Balk, Robert A

    2014-01-01

    The concept of a systemic inflammatory response syndrome (SIRS) to describe the complex pathophysiologic response to an insult such as infection, trauma, burns, pancreatitis, or a variety of other injuries came from a 1991 consensus conference charged with the task of developing an easy-to-apply set of clinical parameters to aid in the early identification of potential candidates to enter into clinical trials to evaluate new treatments for sepsis. There was recognition that a diverse group of injuries produced a common inflammatory response in the host and provided attractive targets for new anti-inflammatory molecules designed to prevent further propagation and/or provide specific treatment. Effective application of these new anti-inflammatory strategies necessitated identification of early clinical markers that could be assessed in real-time and were likely to define a population of patients that would have a beneficial response to the targeted intervention. It was felt that early clinical manifestations might be more readily available to clinicians than more sophisticated and specific assays for inflammatory substances that were systemically released by the network of injurious inflammatory events. Therefore, the early definition of a systemic inflammatory response syndrome (SIRS) was built upon a foundation of basic clinical and laboratory abnormalities that were readily available in almost all clinical settings. With further refinement, it was hoped, that this definition would have a high degree of sensitivity, coupled with a reasonable degree of specificity. This manuscript reviews the derivation, application, utilization, potential benefits, and speculation regarding the future of the SIRS definition.

    Full Text Available Backgrounds:Magnesium has been known for its antioxidative and antiinflammatory properties in many studies. In this study two dosing regimens of magnesium were compared with a placebocontrol group in order to investigate safety and efficacy of high doses of intravenous magnesium sulfate infusion on critically ill trauma patients. Inflammatory and oxidative factors were measured in this trial.Methods:45 trauma patients with systemic inflammatory response syndromes (SIRS were randomly assigned into 2 treatment and one placebo groups. The high dose group received 15 g MgSO4, low dose group received 7.5 g of MgSO4 over 4 hour infusion, and placebo groupreceived saline alone. The initial and post magnesium sulfate injections levels of tumor necrosis factor alpha (TNF-α, total antioxidant power and lipid peroxidation were measured after 6, 18 and 36 hours. The pre-infusion along with 6 and 36 hour level ofmicroalbuminuria were also determined.Results:Repeated measurements illustrated that there was no significant difference in TNF-α, total antioxidant power and lipid peroxidation levels among groups during the period of analysis.The microalbuminuria at 36 hour post infusion of high dose group was lower than that of control group (p = 0.024. Patient’s mortality (28 day was similar among all treatment groups. Both magnesium infusion groups tolerated the drug without experiencing anycomplications.Conclusion:No evidence for antioxidative and antiinflammatory effects of magnesium in traumatic SIRS positive patients was found. Magnesium in high doses may be recommended for traumaticpatients with SIRS status to prevent microalbuminuria.

    Procalcitonin (PCT) has previously been proposed as useful marker to rule out bloodstream-infection (BSI). The objective of this study was to evaluate the sensitivity of different PCT cut-offs for prediction of BSI in patients with community (CA)- and hospital-acquired (HA)-BSI. A total of 898 patients fulfilling systemic-inflammatory-response-syndrome (SIRS) criteria were enrolled in this prospective cohort study at the Medical University of Graz, Austria. Of those 666 patients had positive blood cultures (282 CA-BSI, 384 HA-BSI, enrolled between January 2011 and December 2012) and 232 negative blood cultures (enrolled between January 2011 and July 2011 at the emergency department). Blood samples for determination of laboratory infection markers (e.g. PCT) were collected simultaneously with blood cultures. Procalcitonin was significantly (p SIRS patients with bacteremia/fungemia than in those without. Receiver operating characteristic curve analysis revealed an area under the curve (AUC) value of 0.675 for PCT (95% CI 0.636-0.714) for differentiating patients with BSI from those without. AUC for IL-6 was 0.558 (95% CI 0.515-0.600). However, even at the lowest cut-off evaluated (i.e. 0.1 ng/ml) PCT failed to predict BSI in 7% (n = 46) of patients. In the group of patients with SIRS and negative blood culture 79% (n = 185) had PCT levels > 0.1. Procalcitonin was significantly higher in patients with BSI than in those without and superior to IL-6 and CRP. The clinical importance of this is questionable, because a suitable PCT threshold for excluding BSI was not established. An approach where blood cultures are guided by PCT only can therefore not be recommended. © 2014 John Wiley & Sons Ltd.

    Gilman, James K

    2017-03-01

    The purpose of this article is to examine the Army service of Dr. William H. Welch during World War I. Archival research utilizing prime source documents in the William H. Welch Collection of the Alan M. Chesney Medical Archives for the Johns Hopkins Medical Institutions. Welch joined the Army at the age of 67 after serving as one of the principal transformational forces for reforming medical education in the United States and founding the first academic institution for educating public health professionals in the United States, the Johns Hopkins School of Public Health and Hygiene. His longstanding relationship with Army Surgeon General William Gorgas served as the backdrop for Welch's service. Welch served as both a staff officer and as a traveling medical inspector general, assessing the medical care of troops preparing for overseas duty. He did not adapt particularly well to military dress and decorum but his status as one of the icons of American medicine rendered these shortcomings insignificant. Welch was joined in Army service by a number of American medical luminaries-both Mayo brothers, George Crile, and Harvey Cushing among them. Although Welch remained on active duty for only 13 months, he maintained a nominal relationship with Army medicine through appointment to the Medical Officer Reserve Corps until the time of his death. 2016 marks the centennial of the establishment of the first independent academic institution in America dedicated to education and training of professionals focused on public health and hygiene issues. 2017 marks the centennial of U.S. entry into World War I. Dr. William H. Welch played an important role in both of these historic events and, although his active service was brief, the impact of his example was substantial. Analysis of his military career in its full historical context provides insight into the relationship between academic medicine and military medicine during periods of armed conflict.

    Full Text Available In this article I suggest that historically lyric and narrative are not mutually exclusive categories. Focusing on the case of Sir Philip Sidney’s sonnet sequence, “Astrophil and Stella”, I argue that the fundamentally lyric form of the sonnet functions rhetorically and contextually in such a way as to invite narrative construal. I suggest that this is the norm in pre-Enlightenment poetic practice and theory, something which was perhaps occluded by the decline of interest in rhetoric.

    2017-11-01

    Sir Richard Owen, a Lancastrian, was a prominent biologist, comparative anatomist, geologist, palaeontologist and known for coining the term dinosaur. His expertise in anatomical dissection proved to be one of his biggest assets and aided his career progression at the Royal College of Surgeons and the Zoological Society. Owen's apprenticeship in Lancaster helped him to gain expertise in anatomy and anatomical dissection. The authors aim to provide some novel contextual background to his childhood in Lancaster, his affection for his hometown and his contribution to Lancaster's sanitary reform. The latter aspect of his scientific accomplishments is typically overlooked.

    The years 2007 and 2008 mark the bi-centenary of two brilliant discoveries by Sir Humphry Davy: the isolation of sodium and potassium (1807) and the subsequent first observation (1808) of the beautiful blue and bronze colours now known to be characteristic of the solvated electron(1) in potassium-ammonia systems. In celebration of these dazzling discoveries, we reflect on Davy's many extraordinary contributions to science, technology and poetry. Humphry Davy, a truly great man, of Cornish spirit, brought immeasurable benefits to humankind.

    Full Text Available We discuss multigroup SIRS (susceptible, infectious, and recovered epidemic models with random perturbations. We carry out a detailed analysis on the asymptotic behavior of the stochastic model; when reproduction number ℛ0>1, we deduce the globally asymptotic stability of the endemic equilibrium by measuring the difference between the solution and the endemic equilibrium of the deterministic model in time average. Numerical methods are employed to illustrate the dynamic behavior of the model and simulate the system of equations developed. The effect of the rate of immunity loss on susceptible and recovered individuals is also analyzed in the deterministic model.

    Solar radiation is the driving force for the earth's weather and climate. Understanding the elements of this dynamic energy balance requires accurate measurements of broadband solar irradiance. Since the mid-1990's the ARM Program has deployed pyrheliometers and pyranometers for the measurement of direct normal irradiance (DNI), global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI), and upwelling shortwave (US) radiation at permanent and mobile field research sites. This poster summarizes the basis for assessing the broadband solar radiation data available from the SIRS, SKYRAD, and GNDRAD measurement systems and provides examples of data inspections.

  19. Effect of infection age on an SIR epidemic model with demography on complex networks

    2017-08-01

    For the long term population behavior, demography is a very important factor impacting the disease spread. Infection age also helps us better understand the process of the disease transmission. In this paper, we incorporate these two factors in an SIR epidemic model on complex networks. Through mathematical analysis, the basic reproduction number R0 is shown to be a sharp threshold to determine whether or not the disease spreads. Precisely, if R0 is less than 1 then the disease-free equilibrium is globally asymptotically stable while if R0 is larger than 1 then the endemic equilibrium is globally asymptotically stable. Some simulations are carried out to illustrate the theoretical results.

    2016-11-01

    In this paper, we study the threshold dynamics of a stochastic delayed SIR epidemic model with vaccination. We obtain sufficient conditions for extinction and persistence in the mean of the epidemic. The threshold between persistence in the mean and extinction of the stochastic system is also obtained. Compared with the corresponding deterministic model, the threshold affected by the white noise is smaller than the basic reproduction number Rbar0 of the deterministic system. Results show that time delay has important effects on the persistence and extinction of the epidemic.

    In the 1970's many neurosurgeons gradually adapted microsurgical techniques to spine surgery as the benefits of magnification, illumination, and use of fine instruments in cranial surgery became apparent. In the early 1970 s, Robert W. Williams, а neurosurgeon in private practice in Las Vegas, Nevada, independently began to devise spinal microneurosurgical techniques with the goal of improving surgical outcome in lumbar and cervical surgery. Much of his initial work with microlumbar discectomies and microcervical foraminotomies was presented at annual meetings of the American Association of Neurological Surgeons and Congress of Neurological Surgeons in the 1970s and 1980s. An outsider to organized academic neurosurgery, Dг. Williams found his work was received cautiously and with significant skepticism. He found the orthopedic spine surgery community and journals more receptive, thus much of his earlier work was published in the orthopedic literature. This resulted in an orthopedic and neurosurgical following which was unique at that time. Dr. William's interesting career and contribution to spinal microsurgery is outlined, demonstrating the contributions to surgery, both neurological and orthopedic, that can be achieved by a neurosurgeon in private practice.

    Rosa, Regis Goulart; Moraes, Rafael Barberena; Lisboa, Thiago Costa; Schunemann, Daniel Pretto; Teixeira, Cassiano

    We compared the discriminatory capacity of the sequential organ failure assessment (SOFA) versus the systemic inflammatory response syndrome (SIRS) score for predicting ICU mortality, need for and length of mechanical ventilation, ICU stay, and hospitalization in patients with suspected infection admitted to a mixed Brazilian ICU. We performed a retrospective analysis of a longitudinal ICU database from a tertiary hospital in Southern Brazil. Patients were categorized according to whether they met the criteria for sepsis according to SOFA (variation ≥2 points over the baseline clinical condition) and SIRS (SIRS score ≥2 points). From January 2008 to December 2014, 1487 patients were admitted to the ICU due to suspected infection. SOFA ≥2 identified more septic patients than SIRS ≥2 (79.0% [n=1175] vs. 68.5% [n=1020], pSIRS ≥2 in predicting need for mechanical ventilation (AUROC=0.64 vs. 0.62, p=0.001), ICU stay>7 days (AUROC=0.65 vs. 0.63, p=0.004), and length of hospitalization >10 days (AUROC=0.61 vs. 0.59, p7 days.

  4. On Reading Poems: Visual & Verbal Icons in William Carlos Williams' «Landscape With The Fall Of Icarus»

    Directory of Open Access Journals (Sweden)

    Irene R. Fairley

    1981-09-01

    Full Text Available Williams' admiration for Brueghel's landscape is coded in structural and stylistic correspondences between the poem and the painting. Structures in the poem have effects analogous to the use of devices of color, line, foregrounding in the painting. The poem, like the painting, presents a «neutral» scene but subtly insures the reader's involvement. Further, Williams draws a visual statement so that graphic features suggest a global image isomorphic with the motif of descent. Features of the poem, such as line and clause length, syntactic construction, semantic coherence, are discussed as factors that contribute to rapid glancing and increase readability. A study of readers shows their sensitivity to graphic features including the poem's shape, and corroborates the importance of stylistic features.

  6. Stability Analysis of SIR Model with Distributed Delay on Complex Networks.

    Directory of Open Access Journals (Sweden)

    Chuangxia Huang

    Full Text Available In this paper, by taking full consideration of distributed delay, demographics and contact heterogeneity of the individuals, we present a detailed analytical study of the Susceptible-Infected-Removed (SIR epidemic model on complex population networks. The basic reproduction number [Formula: see text] of the model is dominated by the topology of the underlying network, the properties of individuals which include birth rate, death rate, removed rate and infected rate, and continuously distributed time delay. By constructing suitable Lyapunov functional and employing Kirchhoff's matrix tree theorem, we investigate the globally asymptotical stability of the disease-free and endemic equilibrium points. Specifically, the system shows threshold behaviors: if [Formula: see text], then the disease-free equilibrium is globally asymptotically stable, otherwise the endemic equilibrium is globally asymptotically stable. Furthermore, the obtained results show that SIR models with different types of delays have different converge time in the process of contagion: if [Formula: see text], then the system with distributed time delay stabilizes fastest; while [Formula: see text], the system with distributed time delay converges most slowly. The validness and effectiveness of these results are demonstrated through numerical simulations.

    Room temperature vulcanized silicone rubber (RTV SIR) coatings are employed in order to improve the pollution performance of high voltage ceramic insulators by imparting surface hydrophobicity. In this paper, the performance of three RTV SIR coatings containing different fillers is investigated in a salt-fog test. Alumina trihydrate (ATH) and silica are the fillers included in the formulation, aiming to increase the material endurance to the energy supplied by the surface electrical activity during periods of hydrophobicity loss. The primary action of these fillers is to increase the material heat conductivity, i.e. the amount of energy conducted to the substrate. In addition, in the case of ATH relief is also achieved due to particle decomposition. The results indicate that for the compositions commercially available, where low amounts of fillers are used, and under the conditions of the test, ATH filled coatings performed better than the silica filled ones. This is attributed to ATH decomposition which further relieves the material structure and therefore decelerates material aging.

  8. Resveratrol induces vascular smooth muscle cell differentiation through stimulation of SirT1 and AMPK.

    Directory of Open Access Journals (Sweden)

    Anne Marie Thompson

    Full Text Available Phenotypic plasticity in vascular smooth muscle cells (VSMC is necessary for vessel maintenance, repair and adaptation to vascular changes associated with aging. De-differentiated VSMC contribute to pathologies including atherosclerosis and intimal hyperplasia. As resveratrol has been reported to have cardio- protective effects, we investigated its role in VSMC phenotypic modulation. We demonstrated the novel finding that resveratrol promoted VSMC differentiation as measured by contractile protein expression, contractile morphology and contraction in collagen gels. Resveratrol induced VSMC differentiation through stimulation of SirT1 and AMPK. We made the novel finding that low or high dose resveratrol had an initially different mechanism on induction of differentiation. We found that low dose resveratrol stimulated differentiation through SirT1-mediated activation of AKT, whereas high dose resveratrol stimulated differentiation through AMPK-mediated inhibition of the mTORC1 pathway, allowing activation of AKT. The health effects of resveratrol in cardiovascular diseases, cancer and longevity are an area of active research. We have demonstrated a supplemental avenue where-by resveratrol may promote health by maintaining and enhancing plasticity of the vasculature.

    A major objective of soil moisture-related hydrological-research during NASA's SIR-C/X-SAR mission was to determine and compare soil moisture patterns within humid watersheds using SAR data, ground-based measurements, and hydrologic modeling. Currently available soil moisture-inversion methods using active microwave data are only accurate when applied to bare and slightly vegetated surfaces. Moreover, as the surface dries down, the number of pixels that can provide estimated soil moisture by these radar inversion methods decreases, leading to less accuracy and, confidence in the retrieved soil moisture fields at the watershed scale. The impact of these errors in microwave- derived soil moisture on hydrological modeling of vegetated watersheds has yet to be addressed. In this study a coupled water and energy balance model operating within a topographic framework is used to predict surface soil moisture for both bare and vegetated areas. In the first model run, the hydrological model is initialized using a standard baseflow approach, while in the second model run, soil moisture values derived from SIR-C radar data are used for initialization. The results, which compare favorably with ground measurements, demonstrate the utility of combining radar-derived surface soil moisture information with basin-scale hydrological modeling.

    In 1931 two pharmaceutical drawers containing mineral specimens, belonging to Sir Hans Sloane, the 18th century collector, Royal Physician, President of the Royal Society and of the Royal College of Physicians of London, were found in the Department of Botany of the Natural History Museum (NHM) of London. The drawers, each divided into 49 compartments, contained a total of 107 mineral pharmaceutical specimens, some labelled as mercury or white arsenic.

    Using administrative codes and minimal physiologic and laboratory data, we sought a high-specificity identification strategy for patients whose sepsis initially appeared during their ICU stay. We studied all patients discharged from an academic hospital between September 1, 2013 and October 31, 2014. Administrative codes and minimal physiologic and laboratory criteria were used to identify patients at high risk of developing the onset of sepsis in the ICU. Two clinicians then independently reviewed the patient record to verify that the screened-in patients appeared to become septic during their ICU admission. Clinical chart review verified sepsis in 437/466 ICU stays (93.8%). Of these 437 encounters, only 151 (34.6%) were admitted to the ICU with neither SIRS nor evidence of infection and therefore appeared to become septic during their ICU stay. Selected administrative codes coupled to SIRS criteria and applied to patients admitted to ICU can yield up to 94% authentic sepsis patients. However, only 1/3 of patients thus identified appeared to become septic during their ICU stay. Studies that depend on high-intensity monitoring for description of the time course of sepsis require clinician review and verification that sepsis initially appeared during the monitoring period.

    To understand the effect of impulsive vaccination and restricting infected individuals boarding transports on disease spread, we establish an SIR model with impulsive vaccination, impulsive dispersal and restricting infected individuals boarding transports. This SIR epidemic model for two regions, which are connected by transportation of non-infected individuals, portrays the evolvement of diseases. We prove that all solutions of the investigated system are uniformly ultimately bounded. We also prove that there exists globally asymptotically stable infection-free boundary periodic solution. The condition for permanence is discussed. It is concluded that the approach of impulsive vaccination and restricting infected individuals boarding transports provides reliable tactic basis for preventing disease spread.

    CD133-expressing glioma cells play a critical role in tumor recovery after treatment and are resistant to radiotherapy. Herein, we demonstrated that glioblastoma-derived CD133-positive cells (GBM-CD133 + ) are capable of self-renewal and express high levels of embryonic stem cell genes and SirT1 compared to GBM-CD133 - cells. To evaluate the role of SirT1 in GBM-CD133 + , we used a lentiviral vector expressing shRNA to knock-down SirT1 expression (sh-SirT1) in GBM-CD133 + . Silencing of SirT1 significantly enhanced the sensitivity of GBM-CD133 + to radiation and increased the level of radiation-mediated apoptosis. Importantly, knock-down of SirT1 increased the effectiveness of radiotherapy in the inhibition of tumor growth in nude mice transplanted with GBM-CD133 + . Kaplan-Meier survival analysis indicated that the mean survival rate of GBM-CD133 + mice treated with radiotherapy was significantly improved by Sh-SirT1 as well. In sum, these results suggest that SirT1 is a potential target for increasing the sensitivity of GBM and glioblastoma-associated cancer stem cells to radiotherapy.

    Sir2, an evolutionarily conserved NAD(+)-dependent deacetylase, has been implicated as a key factor in mediating organismal life span. However, recent contradictory findings have brought into question the role of Sir2 and its orthologs in regulating organismal longevity. In this study, we report that Drosophila Sir2 (dSir2) in the adult fat body regulates longevity in a diet-dependent manner. We used inducible Gal4 drivers to knock down and overexpress dSir2 in a tissue-specific manner. A diet-dependent life span phenotype of dSir2 perturbations (both knockdown and overexpression) in the fat body, but not muscles, negates the effects of background genetic mutations. In addition to providing clarity to the field, our study contrasts the ability of dSir2 in two metabolic tissues to affect longevity. We also show that dSir2 knockdown abrogates fat-body dFOXO-dependent life span extension. This report highlights the importance of the interplay between genetic factors and dietary inputs in determining organismal life spans. Copyright © 2012 The Authors. Published by Elsevier Inc.

    William Hooker and his son Joseph were famous as botanists and as the creators of the Royal Botanic Gardens in Kew. Joseph was famous also as the friend and mentor of Charles Darwin. But there was another brother, a little older than Joseph, also a doctor and naturalist. He went to Jamaica in the interests of his health and soon died there of yellow fever. His life was short and tragic with a medical conundrum at its end but its story also illustrates many of the beliefs and concerns that preoccupied doctors in this early Victorian era. It also illustrates the close relationship between medicine and botany that prevailed then.

A form of State which sought to overcome the crisis of capitalism by proposing control over the system. We attempt to demonstrate the relation that should exist, according to Beveridge, the "father" of this model of capitalist State, between the development of a social security system, employment, and the situation of private property, while simultaneously pointing out the specifics and complexity of his ideas in the relation observed between full occupation and private property as basic elements for the construction of a Social Security system.

The patient was treated with balloon angioplasty and stent implantation. Short-term follow-up showed a good clinical result with excellent patency of the stents but early restenosis of the segments in which only balloon angioplasty was performed. These stenoses were subsequently also treated successfully by stent implantation. Stent patency was observed 3 years after the first procedure

    Yoshida, Naoki; Hara, Tadayuki

    2007-04-01

    An SIR epidemic model with density dependent birth and death rates is formulated. In our model it is assumed that the total number of the population is governed by logistic equation. The transmission of infection is assumed to be of the standard form, namely proportional to I(t-h)/N(t-h) where N(t) is the total (variable) population size, I(t) is the size of the infective population and a time delay h is a fixed time during which the infectious agents develop in the vector. We consider transmission dynamics for the model. Stability of an endemic equilibrium is investigated. The stability result is stated in terms of a threshold parameter, that is, a basic reproduction number R0.

    This research study demonstrates a numerical model intended for comprehension the spread of the year 2015 Zika virus disease utilizing the standard SIR framework. In modeling virulent disease dynamics, it is important to explore whether the illness spread could accomplish a pandemic level or it could be eradicated. Information from the year 2015 Zika virus disease event is utilized and Brazil where the event began is considered in this research study. A three dimensional nonlinear differential equation is formulated and solved numerically utilizing the Euler's method in MS excel. It is appeared from the research study that, with health intercessions of public, the viable regenerative number can be decreased making it feasible for the event to cease to exist. It is additionally indicated numerically that the pandemic can just cease to exist when there are no new infected people in the populace.

  7. Sir John Adams: his legacy to the world of particle accelerators

    Wilson, E J N

    2011-01-01

    John Adams acquired an unrivalled reputation for his leading part in designing and constructing the Proton Synchrotron (PS) in CERN’s early days. In 1968, and after several years heading a fusion laboratory in the UK, he came back to Geneva to pilot the Super Proton Synchrotron (SPS) project to approval and then to direct its construction. By the time of his early death in 1984 he had built the two flagship proton accelerators at CERN and, during the second of his terms as Director-General, he laid the groundwork for the proton–antiproton collider which led to the discovery of the intermediate vector boson. How did someone without any formal academic qualification achieve this? What was the magic behind his leadership? The speaker, who worked many years alongside him, will discuss these questions and speculate on how Sir John Adams might have viewed today’s CERN.

  8. SIR rumor spreading model considering the effect of difference in nodes’ identification capabilities

    Science.gov (United States)

    Wang, Ya-Qi; Wang, Jing

    In this paper, we study the effect of difference in network nodes’ identification capabilities on rumor propagation. A novel susceptible-infected-removed (SIR) model is proposed, based on the mean-field theory, to investigate the dynamical behaviors of such model on homogeneous networks and inhomogeneous networks, respectively. Theoretical analysis and simulation results demonstrate that when we consider the influence of difference in nodes’ identification capabilities, the critical thresholds obviously increase, but the final rumor sizes are apparently reduced. We also find that the difference in nodes’ identification capabilities prolongs the time of rumor propagation reaching a steady state, and decreases the number of nodes that finally accept rumors. Additionally, under the influence of difference of nodes’ identification capabilities, compared with the homogeneous networks, the rumor transmission rate on the inhomogeneous networks is relatively large.

    Li, Dan; Liu, Shengqiang; Cui, Jing'an

    2017-12-01

    This paper studies the spread dynamics of a stochastic SIRS epidemic model with nonlinear incidence and varying population size, which is formulated as a piecewise deterministic Markov process. A threshold dynamic determined by the basic reproduction number R0 is established: the disease can be eradicated almost surely if R0 disease persists almost surely if R0 > 1. The existing method for analyzing ergodic behavior of population systems has been generalized. The modified method weakens the required conditions and has no limitations for both the number of environmental regimes and the dimension of the considered system. When R0 > 1, the existence of a stationary probability measure is obtained. Furthermore, with the modified method, the global attractivity of the Ω-limit set of the system and the convergence in total variation to the stationary measure are both demonstrated under a mild extra condition.

    Nineteenth-century Ireland, and especially Dublin, had a vibrant scientific tradition. And astronomy in particular was seriously cultivated, being part of an Irish tradition extending back to early medieval times. This paper examines principally the career of Sir Robert Stawell Ball, who, while holding three prestigious posts in Ireland, namely those of Andrews Professor at Trinity College, Dublin, Royal Astronomer of Ireland, and Director of the Dunsink Observatory, became famous for his genius as a popular astronomical interpreter, lecturer, and writer. The paper looks at Ball's wider career, the circumstances that provided a receptive market for astronomical information across the English-speaking world, and his massive outreach as both a lecturer and a writer.

    Sepsis is defined as a syndrome combining a systemic inflammatory response with a documented infection. It may progress to more serious cases such as septic shock following the failure of one or more organs and the emergence of hemodynamic defects. Assuming that the emergence of serious septic syndromes may be partially explained by the early loss of regulation of the inflammatory response, we decided to compare, in a transcriptomic perspective, the biological mechanisms expressed during an induced systemic inflammatory response with those expressed during severe septic syndromes. By using open-access transcriptomic databases, we first studied the kinetics of an induced inflammatory response. The use of functional analysis helped us identify discriminating biological mechanisms, such as the mTOR signaling pathway, between the pathological cases of sepsis and non-pathological (i.e., the artificially induced SIRS) cases.

    Two main non-destructive techniques can be used to measure standard 222 Rn gas ampoules: well-type ionization chambers and gamma-ray spectrometry, the former being used in the Système International de Référence (SIR) for international comparison purposes. The reliability of these techniques requires that the variability of the flame-sealed gas glass ampoules used have a negligible influence on the detector response. This variability is studied in this work by considering three parameters: the volume of the ampoule, the position of the sealing point and the thickness of the glass. Results showed that variability of the gas ampoules induced measurement bias larger than the uncertainty of the standard sources. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Sir Isaac Newton, creator of the first and perhaps most important scientific theory, is a giant of the scientific era. Despite this, he has remained inaccessible to most modern readers, indisputably great but undeniably remote. In this witty, engaging, and often moving examination of Newton's life, David Berlinski recovers the man behind the mathematical breakthroughs. The story carries the reader from Newton's unremarkable childhood to his awkward undergraduate days at Cambridge through the astonishing year in which, working alone, he laid the foundation for his system of the world, his Principia Mathematica, and to the subsequent monumental feuds that poisoned his soul and wearied his supporters. An edifying appreciation of Newton's greatest accomplishment, Newton's Gift is also a touching celebration of a transcendent man.

    Franceschetti, Andrea; Pugliese, Andrea

    2008-07-01

    We consider a SIR age-structured model with immigration of infectives in all epidemiological compartments; the population is assumed to be in demographic equilibrium between below-replacement fertility and immigration; the spread of the infection occurs through a general age-dependent kernel. We analyse the equations for steady states; because of immigration of infectives a steady state with a positive density of infectives always exists; however, a quasi-threshold theorem is proved, in the sense that, below the threshold, the density of infectives is close to 0, while it is away from 0, above the threshold; furthermore, conditions that guarantee uniqueness of steady states are obtained. Finally, we present some numerical examples, inspired by the Italian demographic situation, that illustrate the threshold-like behaviour, and other features of the stationary solutions and of the transient.

  16. Optimizing Real-Time Vaccine Allocation in a Stochastic SIR Model.

    Directory of Open Access Journals (Sweden)

    Chantal Nguyen

    Full Text Available Real-time vaccination following an outbreak can effectively mitigate the damage caused by an infectious disease. However, in many cases, available resources are insufficient to vaccinate the entire at-risk population, logistics result in delayed vaccine deployment, and the interaction between members of different cities facilitates a wide spatial spread of infection. Limited vaccine, time delays, and interaction (or coupling of cities lead to tradeoffs that impact the overall magnitude of the epidemic. These tradeoffs mandate investigation of optimal strategies that minimize the severity of the epidemic by prioritizing allocation of vaccine to specific subpopulations. We use an SIR model to describe the disease dynamics of an epidemic which breaks out in one city and spreads to another. We solve a master equation to determine the resulting probability distribution of the final epidemic size. We then identify tradeoffs between vaccine, time delay, and coupling, and we determine the optimal vaccination protocols resulting from these tradeoffs.

    The aim of this study was to explore the effects of parenteral supplementation with omega-3 fish oil emulsion (Omegaven) on systemic inflammatory response syndrome (SIRS) during the initial stage of severe acute pancreatitis (SAP). In a prospective, randomized and controlled trial, 60 patients with SAP were randomized either to treat with conventional therapy (Con group, n=30) or conventional therapy plus intravenous supplementation with omega-3 fish oil emulsion 0.2 g/kg every day (FO group, n=30). The effects were analyzed by the SIRS-related indexes. The results showed that APACHE-II scores in FO group were significantly lower, and the gap increased much farther after the 4th day than those in Con group (PSIRS scores were markedly decreased and the SIRS state vanished after the 4th day; Plasma level of TNF-alpha was significantly reduced, while IL-10 decreased markedly, most prominently between the 4th and 7th day, and the ratio of IL-10/TNF-alpha raised as compared with Con group (PSIRS, markedly retrieve the unbalance of the pro-/anti-inflammatory cytokines, improve severe condition of illness and may provide a new way to regulate the SIRS.

    Full Text Available We compared the discriminatory capacity of the sequential organ failure assessment (SOFA versus the systemic inflammatory response syndrome (SIRS score for predicting ICU mortality, need for and length of mechanical ventilation, ICU stay, and hospitalization in patients with suspected infection admitted to a mixed Brazilian ICU. We performed a retrospective analysis of a longitudinal ICU database from a tertiary hospital in Southern Brazil. Patients were categorized according to whether they met the criteria for sepsis according to SOFA (variation ≥2 points over the baseline clinical condition and SIRS (SIRS score ≥2 points. From January 2008 to December 2014, 1487 patients were admitted to the ICU due to suspected infection. SOFA ≥2 identified more septic patients than SIRS ≥2 (79.0% [n = 1175] vs. 68.5% [n = 1020], p  7 days (AUROC = 0.65 vs. 0.63, p = 0.004, and length of hospitalization >10 days (AUROC = 0.61 vs. 0.59, p 7 days.

    Sepsis is a subtype of systemic inflammatory response syndrome (SIRS), which is characterized by infection. Circulating microRNAs (miRNAs), including miR-150, miR-146a and miR-223, are potential biomarkers of sepsis. In this study, we demonstrated that measuring the relative expression of miR-146a/U6 in plasma, using the 2 -ΔΔCt method, provides a method for differentiating between sepsis and non-sepsis-SIRS. We observed a significant increase in miR-146a expression in the initial cohort of 6 non-sepsis-SIRS patients compared to the 4 sepsis patients (P=0.01) and in the second cohort of 8 non-sepsis-SIRS patients compared to the 10 sepsis patients (P=0.027). Additionally, we identified that sodium citrate and ethylenediaminetetraacetic acid (EDTA) K 2 may be used as anticoagulant reagents. Generation of a standard curve is not necessary in these diagnostic tests, unless the standard of normalization is carefully selected. Thus we provide more detailed guidance for the clinical use of circulating miRNA biomarkers.

    Thrombopoietin (TPO), a growth factor primarily involved in regulating thrombopoiesis, has been recently implicated in the pathogenesis of sepsis. TPO levels are, indeed, greatly increased in patients with sepsis compared to control subjects, and correlate with sepsis severity. The aim of this study was to evaluate TPO as predictive biomarker of sepsis and of sepsis severity in patients entering the emergency department (ED) with systemic inflammatory response syndrome (SIRS). This was a prospective observational study. Ours is a sub-study of the 'Need-speed trial', a multi-center observational study involving six Italian centers affiliated to the GREAT Italian Network. TPO was measured by ELISA. We enrolled 13 patients with SIRS (6 with acute pancreatitis, 3 with acute heart failure, 1 with pulmonary embolism, and 3 with allergic reactions), and 40 patients with sepsis, eight of whom had severe sepsis and three septic shock. TPO was significantly higher in patients with sepsis than with SIRS. In addition, TPO was higher in patients with severe sepsis than with sepsis, and in patients with septic shock than with severe sepsis, although these differences did not reach the statistical significance. Our preliminary results suggest that TPO may have the potential to be considered a promising early biomarker for both the diagnosis of sepsis and the assessment of sepsis severity in patients with SIRS entering the ED.

  5. [50 years of total hip prosthesis--a tribute to Prof. Sir John Charnley].

    Mikić, Zelimir Dj; Lesić, Aleksandar R

    2013-01-01

    November 2012 marked the 50th anniversary of the first implantation of a successful and long-lived hip endoprosthesis, which was performed by Prof Sir John Charnley in the "Centre for Hip Surgery" at a small country place in the north-west England. John Charnley (1911-1982) finished medical school at the Victoria University of Manchester in 1935, and than started training in orthopaedics at the Manchester Royal Infirmary, and completed it after the Second World War, in which he served as a volunteer. After that he continued working in the same hospital, and, apart from that he worked as a lecturer at the University of Manchester, and from 1949 as a visiting surgeon in the Wrightington Hospital. In 1958 Charnley decided to put his efforts into the development of hip replacement research and surgery, and initiated the foundation of the "Centre for Hip Surgery" with Biomechanical laboratory in the Wrightington Hospital in 1960, where the intesive basic and clinical research started, and becuase of that Charnley in 1962 left Manchester and moved with a full time practice at the Wrightington Hospital. That period of research time was not easy, there were many "trial and tribulations", but, owing to the tenacity and inventive mind of Charnley, in 1962 a new prosthesis consisting of a cemented metal stem with a 22 mm head articulating with a cemented polyethilene acetabular component, and with a low frictional torque was designed. The first such prosthesis, which later produced excellent long-term results, was implanted on November 22nd, 1962, and today, when we look back over a distance of fifty years, we can conclude that that day could be considered as a beginning of a modem aloarthroplastic surgery, and certainly as one of the greatest orthopaedic advance in the whole of the 20th century; and all that was initiated and promoted by Prof. Sir John Charnley.

  6. Face processing in Williams syndrome is already atypical in infancy

    Full Text Available Face processing is a crucial socio-cognitive ability. Is it acquired progressively or does it constitute an innately-specified, face-processing module? The latter would be supported if some individuals with seriously impaired intelligence nonetheless showed intact face-processing abilities. Some theorists claim that Williams syndrome (WS provides such evidence since, despite IQs in the 50s, adolescents/adults with WS score in the normal range on standardised face-processing tests. Others argue that atypical neural and cognitive processes underlie WS face-processing proficiencies. But what about infants with WS? Do they start with typical face-processing abilities, with atypicality developing later, or are atypicalities already evident in infancy? We used an infant familiarisation/novelty design and compared infants with WS to healthy controls as well as to a group of infants with DS matched on both mental and chronological age. Participants were familiarised with a schematic face, after which they saw a novel face in which either the features (eye shape were changed or just the configuration of the original features. Configural changes were processed successfully by controls, but not by infants with WS who were only sensitive to featural changes and who showed syndrome-specific profiles different from infants with the other neurodevelopmental disorder. Our findings indicate that theorists can no longer use the case of Williams syndrome to support claims that evolution has endowed the human brain with an independent face-processing module.

  7. William John Burchell: The multi-skilled polymath

    Full Text Available On the bicentenary of William John Burchell’s sojourn and journey in southern Africa, we review his contribution to science in the region. In November 1810, Burchell arrived in Cape Town and, in mid-1811, he set off on a 4-year, 7000-km journey of scientific exploration. When he returned to Cape Town in April 1815, he had amassed 63 000 specimens and 500 drawings. Burchell is remembered mainly for his contributions to descriptive and philosophical aspects of natural history of the country. He is less well known for some significant and novel contributions to the earth sciences, the social sciences and even astronomy. Burchell’s observations in physical geography and geology and his contribution to cartography have received little attention. In natural history, some of his views were prescient of the concepts of evolution and holism. In the social sciences, he provided unique ethnographic descriptions, developed an orthography of two indigenous languages and produced drawings that have attracted international research. William John Burchell is worthy of our memory.

  8. William James, Nitrous Oxide, and the Anaesthetic Revelation.

    William James greatly influenced the fields of psychology, philosophy, and religion during the late 19 th and early 20 th centuries. This was the era of Modernism, a time when many writers rejected the certainty of Enlightenment ideals. Positivism, which rose to prominence in the early 19th century, had emphasized physical phenomena, empirical evidence, and the scientific method. Darwin's On the Origin of Species (1859), with its theory of natural selection, provided an explanation for the evolution of species apart from a divine Creator. Within this context, William James served as a "mediator between scientific agnosticism and the religious view of the world." James' own experience inhaling nitrous oxide played an important role in shaping his views. For James, the use of nitrous oxide served a key role in elucidating some of his most central ideas: 1) the value of religion, and the emphasis on mysticism and revelation (as opposed to theology and doctrine) as religion's foundation; 2) the universe as pluralistic (as opposed to absolutist, constant, eternal), driven by chance, experience, and change.

    In this retrospective study we assessed the frequency of hypogammaglobulinemia in 708 patients with SIRS, severe sepsis and septic shock. We evaluated the relationship between hypogammaglobulinemia IgG, IgM and 28 day mortality. Total of 708 patients and 1,513 samples were analyzed. In the three subgroups we investigated, patients met the criteria of SIRS, severe sepsis and septic shock. IgG hypogammaglobulinemia was demonstrated in 114 patients with severe sepsis (25.2%), 11 septic shock patients (24.4%), and in 29 SIRS patients (13.9%). IgM hypogammaglobulinemia was documented in 55 patients with severe sepsis (12.2%), 6 septic shock patients (13.3%), and in 17 SIRS patients (8.1%). Mortality of patients with severe sepsis and normal IgG levels was significantly lower (111 patients; 32.8%) compared with those with IgG hypogammaglobulinemia (49 patients; 43.0%; p=0.001). Mortality of patients with septic shock and IgG hypogammaglobulinemia (n=5) was significantly higher compared with those with normal IgG levels (45.5% vs. 38.2%; p=0.001). Mortality of patients with severe sepsis and IgM hypogammaglobulinemia did not differ from that of patients with normal IgM levels (37.0 vs. 41.8%). Mortality of patients with septic shock and IgM hypogammaglobulinemia was significantly higher compared with those with normal IgM levels (50% vs. 38.5%; p=0.0001). This study documented relatively high incidence of hypogammaglobulinemia IgG and IgM in patients with severe sepsis, septic shock and SIRS respectively. The presence of IgG hypogammaglobulinemia in patients with severe sepsis is independent factor of mortality.

    Early detection of the causing microorganism and timely therapeutic intervention are crucial for improved outcome of patients with sepsis. Quite recently, we evaluated the technical and diagnostic feasibility of a commercial multiplex real-time polymerase chain reaction (PCR) (LightCycler SeptiFast® assay) for detection of blood stream infections in a cohort of intensive care unit (ICU) patients with the risk of abdominal sepsis. The PCR positivity rate showed a high coincidence with systemic inflammatory response syndrome (SIRS; 75.8%). In this study, we focussed on patients from the same surgical ICU with upcoming SIRS and addressed the utility on therapeutic decision making following diagnostic application of PCR in addition and comparison to conventional microbiological and laboratory tests. In total, 104 patients on the ICU fulfilling the American College of Chest Physicians/Society of Critical Care Medicine SIRS criteria were enrolled. Blood samples were taken within 24 h of upcoming SIRS. Some 39.9% (n = 59) of the blood samples (n (Total) = 148) were positive using multiplex-PCR and 20.3% (n = 30) using conventional culture. In 11.4% of all samples, multiplex-PCR detected more than one microorganism. Among the 77 microorganisms identified by multiplex-PCR, only 25 (32.5%) could be confirmed by blood culture; an additional 17 could be confirmed by microbiological test results from other significant patient specimen. Positive blood samples independent of the detection method were characterised by significant elevated levels of procalcitonin (p SIRS. Thus, we showed for the first time that PCR test results guide clinical treatment successfully.

    The objective of the study was to determine the accuracy of phospholipase A2 group II (PLA2-II), interferon-gamma-inducible protein 10 (IP-10), angiopoietin-2 (Ang-2), and procalcitonin (PCT) plasma levels in early ruling in/out of sepsis among systemic inflammatory response syndrome (SIRS) patients. Biomarker levels were determined in 80 SIRS patients during the first 4 h of admission to the medical ward. The final diagnosis of sepsis or non-infective SIRS was issued according to good clinical practice. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for sepsis diagnosis were assessed. The optimal biomarker combinations with clinical variables were investigated by logistic regression and decision tree (CART). PLA2-II, IP-10 and PCT, but not Ang-2, were significantly higher in septic (n = 60) than in non-infective SIRS (n = 20) patients (P ≤ 0.001, 0.027, and 0.002, respectively). PLA2-II PPV and NPV were 88 and 86%, respectively. The corresponding figures were 100 and 31% for IP-10, and 93 and 35% for PCT. Binary logistic regression model had 100% PPV and NPV, while manual and software-generated CART reached an overall accuracy of 95 and 98%, respectively, both with 100% NPV. PLA2-II and IP-10 associated with clinical variables in regression or decision tree heterogeneous models may be valuable biomarkers for sepsis diagnosis in SIRS patients admitted to medical ward (MW). Further studies are needed to introduce them into clinical practice.

    Klein Klouwenberg, Peter M C; Ong, David S Y; Bonten, Marc J M; Cremer, Olaf L

    2012-05-01

    To quantify the effects of minor variations in the definition and measurement of systemic inflammatory response syndrome (SIRS) criteria and organ failure on the observed incidences of sepsis, severe sepsis and septic shock. We conducted a prospective, observational study in a tertiary intensive care unit in The Netherlands between January 2009 and October 2010. A total of 1,072 consecutive adults were included. We determined the upper and lower limits of the measured incidence of sepsis by evaluating the influence of the use of an automated versus a manual method of data collection, and variations in the number of SIRS criteria, concurrency of SIRS criteria, and duration of abnormal values required to make a particular diagnosis. The measured incidence of SIRS varied from 49% (most restrictive setting) to 99% (most liberal setting). Subsequently, the incidences of sepsis, severe sepsis and septic shock ranged from 22 to 31%, from 6 to 27% and from 4 to 9% for the most restrictive versus the most liberal measurement settings, respectively. In non-infected patients, 39-98% of patients had SIRS, whereas still 17-6% of patients without SIRS had an infection. The apparent incidence of sepsis heavily depends on minor variations in the definition of SIRS and mode of data recording. As a consequence, the current consensus criteria do not ensure uniform recruitment of patients into sepsis trials.

    The systemic inflammatory response syndrome (SIRS) criteria have not been validated in patients with hematologic malignancies (HM). To determine whether daily assessment of SIRS criteria allows early identification of HM patients who will develop septic shock (SS). Observational, single-center,nested case-control study. Oncology unit of a tertiary care center. 547 consecutive, hospitalized, HM subject were enrolled. Using incidence-density sampling, 184 controls were matched to 46 SS cases. The study exposure was the SIRS score. The study outcome was the development of SS during the hospitalization. 8.4% of subjects developed SS. SIRS scores measured 24 hours prior to SS were significantly higher in cases than in controls (2.1 vs. 1.4,pSIRS cutpoints, fever, tachypnea and tachycardia were each associated with the onset of SS. Population-specific SIRS criteria were empirically derived. Single-center study. Further validation is warranted. SIRS can identify HM patients at risk for SS at least 24 hours before SS onset. These data may lead to evidence-based guidelines using routine vital signs to risk-stratify HM patients for SS.

    Williams-Beuren syndrome is a multisystemic genetic disorder caused by a contiguous gene deletion at 7q11.23. Keratoconus is a complex disease and it is suspected to have a genetic origin, although the specific gene responsible for keratoconus has not been identified. Although there are several ocular features in Williams-Beuren syndrome, keratoconus is not regularly described as part of this syndrome. To report a new patient with keratoconus and Williams-Beuren syndrome. This is the third case of an association between Williams-Beuren syndrome and keratoconus. The authors believe that the Williams-Beuren syndrome chromosome region can be a possible target for further investigation as the genetic basis of keratoconus.

    2015-01-01

    This article pays homage to the life and work of a veritable pioneer in toxicology and drug metabolism, namely a Welshman, Richard Tecwyn Williams, FRS. Professor Williams, or RT as he was known, made major contributions to knowledge about the metabolism and toxicology of drugs and xenobiotics during a scientific career spanning nearly 50 years. Author or coauthor of close to 400 research articles and reviews, including a classic book, entitled Detoxication Mechanisms, Williams and his research school investigated virtually all aspects of drug metabolism, especially conjugations. In particular, the concepts of phase 1 and phase II metabolic pathways were introduced by Williams; the biliary excretion of drugs was extensively studied as were species differences in drug metabolism and detoxication. Besides investigating the metabolism of many pharmaceutical drugs, such as sulfonamides and thalidomide, Williams and his group investigated the disposition and fate in the body of organic pesticides and recreational drugs of abuse, such as amphetamine, methamphetamine and lysergic acid diethylamide (LSD).

    Cationic polyurethane, a biodegradable non-viral vector, protects DNA from nuclease degradation and helps to deliver genes efficiently. Oct4, a POU-domain transcription factor, is highly expressed in maintaining pluripotency and cellular reprogramming process in stem cells. SirT1, a NAD-dependent histone deacetylase, is an essential mediator of cellular longevity. Herein we demonstrated that both Oct4 and SirT1 (Oct4/SirT1) expression was decreased in an age-dependent manner in retina with aged-related macular degeneration and retinal pigment epithelium cells (RPEs). To investigate the possible rescuing role of Oct4/SirT1, polyurethane-short branch polyethylenimine (PU-PEI) was used to deliver Oct4/SirT1 into aged RPEs (aRPEs) or light-injured rat retinas. Oct4/SirT1 overexpression increased the expression of several progenitor-related genes and the self-renewal ability of aRPEs. Moreover, Oct4/SirT1 overexpression resulted in the demethylation of the Oct4 promoter and enhanced the expression of antioxidant enzymes, which was accompanied by a decrease in intracellular ROS production and hydrogen peroxide-induced oxidative stress. Importantly, PU-PEI-mediated Oct4/SirT1 gene transfer rescued retinal cell loss and improved electroretinographic responses in light-injured rat retinas. In summary, these data suggest that PU-PEI-mediated delivery of Oct4/SirT1 reprograms aRPEs into a more primitive state and results in cytoprotection by regulating the antioxidative capabilities of these cells.

  10. What motion is: William Neile and the laws of motion.

    Science.gov (United States)

    Kemeny, Max

    2017-07-01

    In 1668-1669 William Neile and John Wallis engaged in a protracted correspondence regarding the nature of motion. Neile was unhappy with the laws of motion that had been established by the Royal Society in three papers published in 1668, deeming them not explanations of motion at all, but mere descriptions. Neile insisted that science could not be informative without a discussion of causes, meaning that Wallis's purely kinematic account of collision could not be complete. Wallis, however, did not consider Neile's objections to his work to be serious. Rather than engage in a discussion of the proper place of natural philosophy in science, Wallis decided to show how Neile's preferred treatment of motion lead to absurd conclusions. This dispute is offered as a case study of dispute resolution within the early Royal Society.

  11. The Values of Masculinity in William Shakespeare’s Macbeth

    2017-04-01

    Full Text Available The theme of gender plays a vital role in William Shakespeare’s famous political play Macbeth. From the very beginning of the play the dramatist focuses on the importance of masculinity in gaining power and authority. Lady Macbeth along with the three witches are as important characters as Macbeth. Because they influence Macbeth profoundly. And Shakespeare very carefully draws the character of Lady Macbeth who being a female sometimes exhibits more masculinity than Macbeth. Similarly is the case of the three witches. Though they look like women they are also bearded which prove the presence of masculinity in their nature. Throughout the play several times the exposition of masculinity is demanded from the character of Macbeth. So the value of masculinity plays an important part in the drama.

  12. Beat Perception and Sociability: Evidence from Williams Syndrome.

    Lense, Miriam D; Dykens, Elisabeth M

    2016-01-01

    Beat perception in music has been proposed to be a human universal that may have its origins in adaptive processes involving temporal entrainment such as social communication and interaction. We examined beat perception skills in individuals with Williams syndrome (WS), a genetic, neurodevelopmental disorder. Musical interest and hypersociability are two prominent aspects of the WS phenotype although actual musical and social skills are variable. On a group level, beat and meter perception skills were poorer in WS than in age-matched peers though there was significant individual variability. Cognitive ability, sound processing style, and musical training predicted beat and meter perception performance in WS. Moreover, we found significant relationships between beat and meter perception and adaptive communication and socialization skills in WS. Results have implications for understanding the role of predictive timing in both music and social interactions in the general population, and suggest music as a promising avenue for addressing social communication difficulties in WS.

    William Whewell's work on historical science has received some attention from historians and philosophers of science. Whewell's own work on the history of German Gothic church architecture has been touched on within the context of the history of architecture. To a large extent these discussions have been conducted separately. I argue that Whewell intended his work on Gothic architecture as an attempt to (help) found a science of historical architecture, as an exemplar of historical science. I proceed by analyzing the key features of Whewell's philosophy of historical science. I then show how his architectural history exemplifies this philosophy. Finally, I show how Whewell's philosophy of historical science matches some developments in a science (biological systematics) that, in the mid-to late-nineteenth century, came to be reinterpreted as a historical science. I comment briefly on Whewell as a potential influence on nineteenth century biology and in particular on Darwin. Copyright © 2016 Elsevier Ltd. All rights reserved.

    William Herschel (Fig. 1) is rightfully known as one of the greatest astronomers of all time. Born in Hanover (in modern Germany) in 1738, Herschel immigrated to England in 1757 and began a successful career as a professional musician. Later in life Herschel developed a strong interest in astronomy. He began making his own reflecting telescopes in 1774, and soon his telescopes were recognized as the finest in the world. It was through one of his homemade telescopes, a Newtonian reflector with a focal length of seven feet and an aperture of 6.2 inches, that Herschel first spotted the planet Uranus in 1781. The discovery of a new planet catapulted Herschel to fame and secured him a position as personal astronomer to King George III.

    Williams-Beuren syndrome is the clinical manifestation of a congenital genetic disorder in the elastin gene, among others. There is a history of cardiac arrest refractory to resuscitation manoeuvres in anaesthesia. The incidence of myocardial ischaemia is high during anaesthetic induction, but there are patients who do not have this condition yet also have had very serious cardiac events, and issues that are still to be resolved. Case descriptions will enable the common pathophysiological factors to be defined, and decrease morbidity and mortality. We report the case of a 3-year-old boy with cardiac arrest at induction, rescued with circulatory assistance with extracorporeal membrane oxygenation and hypothermia induced for cerebral protection.

  16. Charles William Lacaillade. Biologist, Parasitologist, Educator, and Mentor.

    Charles William Lacaillade (1904-1978) was an eminent biologist in the middle decades of the twentieth century. He was born in Lawrence, Massachusetts of parents whose ancestors were French Canadians. His father, also named Charles William Lacaillade, was a dentist who graduated from Tufts University School of Dentistry in 1898. His mother, Elodia Eno, came from a family of very successful businessmen. Lacaillade was the third of six children. His two older brothers, Harold Carleton and Hector Eno, both graduated from the University of Louisville, School of Dentistry, while his younger brother, Lawrence, became a businessman. His sister, Luemma, married Dr. Henry Steadman, a veterinarian, while his youngest sister, Gloria, married a U.S. Army officer, Lieutenant Colonel Victor Anido. Lacaillade received his MS and PhD degrees in biology and zoology from Harvard University. He then became a fellow at The Rockefeller Institute for Medical Research. At both institutions, he studied under some of the most eminent biological scientists of the time. These included Rudolf W. Glaser, George Howard Parker, Theobald Smith, Carl TenBroeck, and William Morton Wheeler. At the Rockefeller Institute, he co-discovered the vector and mode of transmission of Eastern Equine Encephalomyelitis. This discovery, and the research he conducted with Rudolf W. Glaser, quickly established him as an outstanding biological researcher. However, a change in leadership at the Rockefeller Institute resulted in research priorities being given to the disciplines of general physiology, physical chemistry, and nutrition. This shift in the research agenda away from the biological sciences precluded career advancement at the Rockefeller Institute for post-doctoral fellows like Lacaillade. It was the height of the Great Depression, and even biologists with terminal doctoral degrees found it difficult to find positions. In 1935, Lacaillade accepted a position as an assistant in biology at St. John

    2010-10-01

    This article is part of an occasional series profiling editors of the American Journal of Clinical Hypnosis (AJCH). William E. Edmonston was the second editor, succeeding Milton H. Erickson. His research focused on the use of conditioning paradigms and psychophysiological measures to explore a wide variety of hypnotic phenomena, leading to a "neo-Pavlovian" theory of neutral hypnosis as physiological relaxation (anesis). A longtime professor of psychology at Colgate University, he created an interdisciplinary undergraduate major in neuroscience, and was named New York State College Professor of the Year in 1988. He gave the Journal a new look, and a greater balance of clinical and experimental papers. The article also provides background on George Barton Cutten, George H. Estabrooks, and Frank A. Pattie, pioneers of hypnosis who were linked to Edmonston.

  19. Syntax in Spanish-speaking children with Williams syndrome.

    The syntactic skills of Spanish-speaking children with Williams syndrome (WS) were assessed in different areas (phrase structure, recursion, and bound anaphora). Children were compared to typically-developing peers matched either in chronological age (CA-TD) or in verbal age (VA-TD). In all tasks children with WS performed significantly worse than CA-TD children, but similarly to VA-TD children. However, significant differences were observed in specific domains, particularly regarding sentences with cross-serial dependencies. At the same time, children with WS were less sensitive to syntactic constraints and exhibited a poorer knowledge of some functional words (specifically, of nonreflexive pronouns). A processing bottleneck or a computational constraint may account for this outcome. Copyright © 2016 Elsevier Inc. All rights reserved.

    Prior work suggests that our understanding of how things work ("intuitive physics") and how people work ("intuitive psychology") are distinct domains of human cognition. Here we directly test the dissociability of these two domains by investigating knowledge of intuitive physics and intuitive psychology in adults with Williams syndrome (WS) - a genetic developmental disorder characterized by severely impaired spatial cognition, but relatively spared social cognition. WS adults and mental-age matched (MA) controls completed an intuitive physics task and an intuitive psychology task. If intuitive physics is a distinct domain (from intuitive psychology), then we should observe differential impairment on the physics task for individuals with WS compared to MA controls. Indeed, adults with WS performed significantly worse on the intuitive physics than the intuitive psychology task, relative to controls. These results support the hypothesis that knowledge of the physical world can be disrupted independently from knowledge of the social world. Copyright © 2017 Elsevier B.V. All rights reserved.
