    2012-12-01

    Full Text Available Intestinal infections caused by protozoa and helminths are considered a major cause of diseases by infectious processes in the world. The present study aims to conduct a survey regarding the recent years of the prevalence of intestinal parasites in school children in various cities in Brazil, identifying which species are most commonly found and the regions that require greater dedication in this area. The analyzed studies showed that the Northern and Northeastern regions presented a higher prevalence of intestinal parasites, however, in the Southeast, results were encouraging with low levels of contamination by parasites compared to all regions in Brazil. As for intestinal parasites, the most common, found in all Brazilian regions, was Ascaris lumbricoides followed by Giardia lamblia. Therefore, one can conclude that the high prevalence of intestinal parasites in children found in some places in Brazil can demonstrate the need for greater care with basic sanitation and personal hygiene, both in households and in the places of study. These data show the importance of conducting educational programs that will develop personal awareness of parents, families and children themselves.

    Full Text Available We report here partial outcomes of a study aimed to verify future High School teachers' performance when, during the development of a called "Teaching Practice" undergraduate course, were asked to plan, elaborate and teach, in classroom situations, electromagnetism topics to a students class which included visual handicapped pupils. Data analyzed show that the main difficulties presented by the future Physics High School teachers are related to the approach to know physics phenomena as dependent of vision and to break with some elements of the traditional pedagogy. By other hand, as alternatives, future teachers showed creativity in order to surpass passive aptitudes related to this educational problem, working out methodological strategies deprived of the relation knowing/seeing, as well as, the work with orality in a physics education context.

    Full Text Available En este trabajo se describen algunos de los principales desarrollos de las ciencias sociales aplicadas a la salud en México en los últimos 25 años. El artículo inicia con una breve descripción de las tres corrientes fundacionales que han hecho de la salud su objeto de estudio: la antropología médica, de larga tradición en este país; la medicina social, impulsada principalmente desde la Universidad Autónoma Metropolitana-Xochimilco; y la sociología de la salud pública, impulsada desde el Instituto Nacional de Salud Pública. Tras revisar los principales aportes de cada corriente, así como los debates que entre ellas ha tenido lugar; describe los desarrollos recientes en este campo, mismos que constituyen una suerte de "segunda generación" de la sociología médica mexicana. La revisión se centra en los aportes en el campo de lo teórico, lo conceptual, y las áreas con más producción actual. Concluye señalando la importancia de este campo en México y la necesidad de reactivar los intercambios académicos entre las diferentes corrientes de pensamiento, como mecanismo para elevar la calidad de los trabajos.This paper describes the main developments of social sciences applied to health in Mexico.

  10. Fact versus fiction. The socio-economic benefits to be found in teaching critical thinking skills on nuclear waste issues in public schools

    International Nuclear Information System (INIS)

    Anderson, H.

    1984-01-01

    The safe storage of radioactive wastes has been the topic of much heated debate. Many of the concerns raised demonstrate that the public is poorly informed about nuclear matters, bewildered by conflicting testimony and lacking the intellectual skills required to discriminate between statements of fact versus opinion or motive. Recently, the National Council for the Social Studies (NCSS) adopted a set of guidelines intended to encourage a stronger emphasis on urgent science-related social issues in the classroom and to provide for social studies teachers, rational and structure for the presentation of these issues. In this way, the NCSS is moving to meet the needs of the community for greater technological awareness. NCSS believes students need instruction and strategies for evaluating science-related material intelligently. As a case study in point, the topic ''Nuclear Waste: A Science Related Social Issue of Urgent Concern'' was brought before a recent NCSS national meeting. This paper discusses strategies for dealing with nuclear waste issues in the classroom and the potential socio-economic benefits to be found in dispelling myths surrounding nuclear issues

    , which detects small changes in the radial velocity of a star as it wobbles slightly under the gentle gravitational pull from an (unseen) exoplanet, has been most prolific method in the search for exoplanets. In return for building the instrument, the HARPS consortium was granted 100 observing nights per year during a five-year period to carry out one of the most ambitious systematic searches for exoplanets so far implemented worldwide by repeatedly measuring the radial velocities of hundreds of stars that may harbour planetary systems. The programme soon proved very successful. Using HARPS, Mayor's team discovered - among others - in 2004, the first super-Earth (around µ Ara; in 2006, the trio of Neptunes around HD 69830; in 2007, Gliese 581d, the first super Earth in the habitable zone of a small star (eso0722); and in 2009, the lightest exoplanet so far detected around a normal star, Gliese 581e (eso0915). More recently, they found a potentially lava-covered world, with density similar to that of the Earth's (eso0933). "These observations have given astronomers a great insight into the diversity of planetary systems and help us understand how they can form," says team member Nuno Santos. The HARPS consortium was very careful in their selection of targets, with several sub-programmes aimed at looking for planets around solar-like stars, low-mass dwarf stars, or stars with a lower metal content than the Sun. The number of exoplanets known around low-mass stars - so-called M dwarfs - has also dramatically increased, including a handful of super Earths and a few giant planets challenging planetary formation theory. "By targeting M dwarfs and harnessing the precision of HARPS we have been able to search for exoplanets in the mass and temperature regime of super-Earths, some even close to or inside the habitable zone around the star," says co-author Xavier Bonfils. The team found three candidate exoplanets around stars that are metal-deficient. Such stars are thought to be

  12. The founding of Zemun Hospital

    Full Text Available This year Zemun Hospital - Clinical Hospital Center Zemun celebrates 230th anniversary of continuous work, thus becoming the oldest medical facility in Serbia. The exact date of the hospital founding has been often questioned in history. Various dates appeared in the literature, but the most frequent one was 25th of February 1784. Until now, the document which confirms this has never been published. This article represents the first official publication of the document which confirms that Zemun Hospital was indeed founded on this date. The first hospitals started emerging in Zemun when the town became a part of the Habsburg Monarchy. The first sanitary facility ever formed was the “Kontumac” - a quarantine established in 1730. Soon after, two more confessional hospitals were opened. The Serbian (Orthodox Hospital was founded before 1769, whereas the German (Catholic Hospital started working in 1758. Both hospitals were financed, amongst others, by the Town Hall - the Magistrate. In order to improve efficiency of these hospitals, a decision was made to merge them into a single City Hospital. It was founded on 25th February 1784, when the General Command ordered the Magistrate of Zemun to merge the financess of all existing hospitals and initiate the construction of a new building. Although financially united, the hospitals continued working in separate buildings over a certain period of time. The final, physical merging of these hospitals was completed in 1795.

    teachers' investigation of their own practice. By listening to hospitalized children, and based on readings of Walter Benjamin, this text proposes to challenge the thinking that has dominated the educational scene in Brazil. Even though this hegemonic thinking may have us believe there are no alternatives, the proposals for reforms are varied and refute the ideology disseminated by the media. Such reforms spring from the base of society and are articulated to popular segments whose protagonists are the educators. The founding experiences both inside and outside of public schools seek to respond to the changes of our times. The society of media information and visual bombardment gives up reflecting on and carefully analyzing the cultural and educational production that invade it, reproducing as dogmas the parlance produced by the media. What is the place for excluded individuals in a society of the spectacle? In a society that promises easy profits, rapid celebrity and knowledge without learning? Amidst the complex informational culture of disconnected discourses, what seems to be usual for most hospitalized children in Brazil is that they are marked by the cycle of poverty, exclusion and absence of anybody who, allowing them to speak, listens to their voices. It can be concluded that listening to the narrative of the excluded has consequently implications to the expansion of educational experiences that can tell a different story: that of a more humanized world.

  16. Lightweight Double Neutron Star Found

    More than forty years after the first discovery of a double neutron star, we still havent found many others but a new survey is working to change that.The Hunt for PairsThe observed shift in the Hulse-Taylor binarys orbital period over time as it loses energy to gravitational-wave emission. [Weisberg Taylor, 2004]In 1974, Russell Hulse and Joseph Taylor discovered the first double neutron star: two compact objects locked in a close orbit about each other. Hulse and Taylors measurements of this binarys decaying orbit over subsequent years led to a Nobel prize and the first clear evidence of gravitational waves carrying energy and angular momentum away from massive binaries.Forty years later, we have since confirmed the existence of gravitational waves directly with the Laser Interferometer Gravitational-Wave Observatory (LIGO). Nonetheless, finding and studying pre-merger neutron-star binaries remains a top priority. Observing such systems before they merge reveals crucial information about late-stage stellar evolution, binary interactions, and the types of gravitational-wave signals we expect to find with current and future observatories.Since the Hulse-Taylor binary, weve found a total of 16 additional double neutron-star systems which represents only a tiny fraction of the more than 2,600 pulsars currently known. Recently, however, a large number of pulsar surveys are turning their eyes toward the sky, with a focus on finding more double neutron stars and at least one of them has had success.The pulse profile for PSR J1411+2551 at 327 MHz. [Martinez et al. 2017]A Low-Mass DoubleConducted with the 1,000-foot Arecibo radio telescope in Puerto Rico, the Arecibo 327 MHz Drift Pulsar Survey has enabled the recent discovery of dozens of pulsars and transients. Among them, as reported by Jose Martinez (Max Planck Institute for Radio Astronomy) and coauthors in a recent publication, is PSR J1411+2551: a new double neutron star with one of the lowest masses ever measured

    We assessed whether baseline measurements of physical activity, aerobic fitness, body fat and abdominal fat were predictors of changes in body fat measurements over a two-year period. The study comprised of 204 children aged 9.8 ± 0.6 years with a normal body mass distribution, who recruited from four schools in middle-class areas of Malmö, Sweden, from 2001 to 2004. Peak oxygen uptake and physical activity were measured at baseline. Body fat was measured by dual-energy X-ray absorptiometry at baseline and two years later. Physical activity, aerobic fitness and total body fat or abdominal fat were predictors of change in total body fat or abdominal fat over a period of two years. Changes in the percentage of body fat were not related to any of the baseline measurements. Our two-year follow-up of children with a mean age of 9.8 years at baseline showed that physical activity, aerobic fitness and body fat or abdominal fat predicted changes in total body fat or abdominal fat, but not the percentage of body fat. ©2018 Foundation Acta Paediatrica.

  19. Establishment probability in newly founded populations

    2012-06-01

    Full Text Available Abstract Background Establishment success in newly founded populations relies on reaching the established phase, which is defined by characteristic fluctuations of the population’s state variables. Stochastic population models can be used to quantify the establishment probability of newly founded populations; however, so far no simple but robust method for doing so existed. To determine a critical initial number of individuals that need to be released to reach the established phase, we used a novel application of the “Wissel plot”, where –ln(1 – P0(t is plotted against time t. This plot is based on the equation P0t=1–c1e–ω1t, which relates the probability of extinction by time t, P0(t, to two constants: c1 describes the probability of a newly founded population to reach the established phase, whereas ω1 describes the population’s probability of extinction per short time interval once established. Results For illustration, we applied the method to a previously developed stochastic population model of the endangered African wild dog (Lycaon pictus. A newly founded population reaches the established phase if the intercept of the (extrapolated linear parts of the “Wissel plot” with the y-axis, which is –ln(c1, is negative. For wild dogs in our model, this is the case if a critical initial number of four packs, consisting of eight individuals each, are released. Conclusions The method we present to quantify the establishment probability of newly founded populations is generic and inferences thus are transferable to other systems across the field of conservation biology. In contrast to other methods, our approach disaggregates the components of a population’s viability by distinguishing establishment from persistence.

    2018-06-01

    How did giant black holes grow so big? Astronomers have long had evidence of baby black holes with masses of no more than tens of suns, and of million- or billion-solar-mass behemoths lurking at the centers of galaxies. But middle-size ones, weighing thousands or tens of thousands of suns, seemed to be missing. Their absence forced theorists to propose that supermassive black holes didn't grow gradually by slowly consuming matter, but somehow emerged as ready-made giants. Now, astronomers appear to have located some missing middleweights. An international team has scoured an archive of galaxy spectra and found more than 300 small galaxies that have the signature of intermediate mass black holes in their cores, opening new questions for theorists.

  6. Commentary on Malone: Who Founded Behaviorism?

    Science.gov (United States)

    Reese, Hayne W

    2015-05-01

    Malone (The Behavior Analyst, 37, 1-12 2014) argued that the emergence of behaviorism was inevitable with or without Watson's participation, mainly because protobehavioral ideas and dissatisfaction with classical structuralism were already widespread. However, the first premise is questionable because many of the ideas Malone cited were consistent with structuralism rather than behaviorism, and even if both premises were true they would not make the emergence of behaviorism-or anything else-inevitable. Historical evidence for inevitability is always retrospective and therefore always allows the logical fallacy of "after this, therefore because of this." In the relevant real world Watson existed, he was a psychologist, he was the first to publish an article that described a "behaviorism," and he promoted his behaviorism in later works. Stories about what would have happened without Watson's participation are therefore counterfactual and this lack of historicity makes the stories fictional rather than scientific. In the real world, Watson founded behaviorism.

    Observations made of two common failures of structures founded on peat/organic soil in Johor, Malaysia is presented. Critical evaluation of current lightweight fill technology to mitigate such settlement is also discussed. Lightweight technology, such as Expanded Polystyrene (EPS), has been used in construction on soft yielding ground for decades. Regrettably, some published information of EPS failures to perform on construction sites are also cited in this paper. This paper outlines some concepts leading to the development of an alternative innovative lightweight fill is that the idealised cellular structure of the GCM permit free flow of water and complemented by the mat structure which evens out any differential settlement A further highlight of this paper is the monitoring of the field performance of this lightweight fill (GCM) as a feasible alternative to fill weight reduction on yielding ground.. Hence, a prime research objective was to compare the fill settlements observed with 1m high fill of surcharge loading on peat ground (comparison of the case of using a partial 0.6m high GCM and that of a total of 1m of conventional sand backfill).

    2016-11-01

    Full Text Available We disclose the finding, during a recent archaeological work in the city of Salamanca, of two marble fragments belonging to a statue of a togatus, which we believe could have been part of the decorative and propagandistic program of the forum in the time of the Early Empire. The data that we have about the location and layout of the forum and the various public spaces and buildings that formed it are indeed very limited. The location of this sculpture would confirm and might even provide some more information in this regard. The discovery was made out of archaeological context, because there is no historical stratigraphic sequence in the basement of the site where it appeared, the material and formal characteristics that can be seen in sculpture, along with the space in which it was found, as well as the archaeological context of the area in a broader sense, allow some clarifications on a number of aspects of formal, chronological and interpretive order relating to it.

  9. Did John B. Watson Really "Found" Behaviorism?

    Science.gov (United States)

    Malone, John C

    2014-05-01

    Developments culminating in the nineteenth century, along with the predictable collapse of introspective psychology, meant that the rise of behavioral psychology was inevitable. In 1913, John B. Watson was an established scientist with impeccable credentials who acted as a strong and combative promoter of a natural science approach to psychology when just such an advocate was needed. He never claimed to have founded "behavior psychology" and, despite the acclaim and criticism attending his portrayal as the original behaviorist, he was more an exemplar of a movement than a founder. Many influential writers had already characterized psychology, including so-called mental activity, as behavior, offered many applications, and rejected metaphysical dualism. Among others, William Carpenter, Alexander Bain, and (early) Sigmund Freud held views compatible with twentieth-century behaviorism. Thus, though Watson was the first to argue specifically for psychology as a natural science, behaviorism in both theory and practice had clear roots long before 1913. If behaviorism really needs a "founder," Edward Thorndike might seem more deserving, because of his great influence and promotion of an objective psychology, but he was not a true behaviorist for several important reasons. Watson deserves the fame he has received, since he first made a strong case for a natural science (behaviorist) approach and, importantly, he made people pay attention to it.

  10. Orphan Stars Found in Long Galaxy Tail

    Science.gov (United States)

    2007-09-01

    Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought. The comet-like tail was observed in X-ray light with NASA's Chandra X-ray Observatory and in optical light with the Southern Astrophysical Research (SOAR) telescope in Chile. The feature extends for more than 200,000 light years and was created as gas was stripped from a galaxy called ESO 137-001 that is plunging toward the center of Abell 3627, a giant cluster of galaxies. "This is one of the longest tails like this we have ever seen," said Ming Sun of Michigan State University, who led the study. "And, it turns out that this is a giant wake of creation, not of destruction." Chandra X-ray Image of ESO 137-001 and Tail in Abell 3627 Chandra X-ray Image of ESO 137-001 and Tail in Abell 3627 The observations indicate that the gas in the tail has formed millions of stars. Because the large amounts of gas and dust needed to form stars are typically found only within galaxies, astronomers have previously thought it unlikely that large numbers of stars would form outside a galaxy. "This isn't the first time that stars have been seen to form between galaxies," said team member Megan Donahue, also of MSU. "But the number of stars forming here is unprecedented." The evidence for star formation in this tail includes 29 regions of ionized hydrogen glowing in optical light, thought to be from newly formed stars. These regions are all downstream of the galaxy, located in or near the tail. Two Chandra X-ray sources are near these regions, another indication of star formation activity. The researchers believe the orphan stars formed within the last 10 million years or so. The stars in the tail of this fast-moving galaxy, which is some 220 million light years away, would be much more isolated than the vast majority of stars in galaxies. H-alpha Image of

  12. The founding of CEBAF, 1979 to 1987

    Westfall, C.

    1995-01-01

    -nuclear physics had attracted a considerable following. The growing electro-nuclear physics community was eager to find a scheme to permit virtually continuous acceleration, which would greatly improve the capability of performing coincidence experiments. In the words of the UVa conference proceedings, this experimental capability promised to open entire new areas of nuclear physics. Convinced that he could be the one to design the necessary groundbreaking machine after hearing the ideas of Loew and Servranckx, McCarthy began gathering a small accelerator building team. Against all odds, McCarthy's pipe dream resulted in the construction of a major accelerator laboratory, the Continuous Electron Beam Accelerator Facility (CEBAF). The founding of CEBAF is a tale of luck, perseverance, the triumph of flexible amateurism over rigid professionalism, and ironically, the potential of amateurs when supported by a thoroughly professional international network with well-defined methods for organizing and building accelerators. The CEBAF tale also has a surprise ending, for at the last minute, McCarthy's pipe dream was radically transformed by Hermann Grunder, who would direct the construction of the project. The twists and turns of this tale reveal many lessons about what aids and what detracts from the success of a large, federally sponsored scientific project

A random selection of 150 students from a population of senior high school students in Ghana were asked to complete the Eating Habits Questionnaire for Adolescents. Data were analyzed by the use of bivariate correlation, t test, and multiple regression analytical techniques using SPSS version 16. The findings revealed a significant positive relationship between peer influence and eating habits suggesting that the higher the peer pressure, the more unhealthy the students’ eating habits. Counterintuitively, parental and media influences did not significantly correlate with students’ eating habits. Gender difference in eating habits suggested that girls had more unhealthy eating habits than boys. Finally, multiple regression analysis revealed that peer influence was a better predictor of students’ eating habits than parental and media influences. The findings were discussed and recommendations were given in light of the study’s limitations.

    Two parasitic amoebian species are found in mollusks of the water bodies of Ukraine. Vahlkampfia sp. is found in hepatopankreas of Unio conus Spengler, 1793, and Acanthamoeba sp. is observed in mantle cavity of Viviparus viviparus Linnaeus, 1758. For these protist species, the mollusks are shown to be intermediate hosts where amoebae feed and reproduce. An experimental infection with Vahlkampfia sp. and Acanthamoeba sp. was not successful, no pathological changes in mollusks were observed. These amoebae are successfully cultured in fresh water and agar medium, hence we can safely consider them free-living. Copyright © 2017 Elsevier Inc. All rights reserved.

    These are turbulent times for American neurosurgery. It is important to look ahead and prepare for the future but it is also important to look back-for it is memory and tradition that prevent the tyranny of the present. It is impossible to know where we are going if we don't remember where we were. In this paper I want to discuss the founding principles of neurosurgery-the principles that have allowed neurosurgery to prosper in its first century-and to stress the importance of adhering to these principles in times of change. I also want to talk to you about how the American Association of Neurological Surgeons (AANS) is helping neurosurgeons honor our founding principles, while preparing neurosurgery for its second century.

    2017-10-01

    In January 2017, counterfeits of the hepatitis C drug 'HARVONI ® Combination Tablets' (HARVONI ® ) were found at a pharmacy chain through unlicensed suppliers in Japan. A total of five lots of counterfeit HARVONI ® (samples 1-5) bottles were found, and the ingredients of the bottles were all in tablet form. Among them, two differently shaped tablets were present in two of the bottles (categorized as samples 2A, 2B, 4A, and 4B). We analyzed the total of seven samples by high-resolution LC-MS, GC-MS and NMR. In samples 2A, 3 and 4B, sofosbuvir, the active component of another hepatitis C drug, SOVALDI ® Tablets 400 mg (SOVALDI ® ), was detected. In sample 4A, sofosbuvir and ledipasvir, the active components of HARVONI ® , were found. A direct comparison of the four samples and genuine products showed that three samples (2A, 3, 4B) are apparently SOVALDI ® and that sample 2A is HARVONI ® . In samples 1 and 5, several vitamins but none of the active compounds usually found in HARVONI ® (i.e., sofosbuvir and ledipasvir) were detected. Our additional investigation indicates that these two samples are likely to be a commercial vitamin supplement distributed in Japan. Sample 2B, looked entirely different from HARVONI ® and contained several herbal constitutents (such as ephedrine and glycyrrhizin) that are used in Japanese Kampo formulations. A further analysis indicated that sample 2B is likely to be a Kampo extract tablet of Shoseiryuto which is distributed in Japan. Considering this case, it is important to be vigilant to prevent a recurrence of distribution of counterfeit drugs.

  9. On the number of founding germ cells in humans

    Directory of Open Access Journals (Sweden)

    Byers Breck

    2005-08-01

    Full Text Available Abstract Background The number of founding germ cells (FGCs in mammals is of fundamental significance to the fidelity of gene transmission between generations, but estimates from various methods vary widely. In this paper we obtain a new estimate for the value in humans by using a mathematical model of germ cell development that depends on available oocyte counts for adult women. Results The germline-development model derives from the assumption that oogonial proliferation in the embryonic stage starts with a founding cells at t = 0 and that the subsequent proliferation can be defined as a simple stochastic birth process. It follows that the population size X(t at the end of germline expansion (around the 5th month of pregnancy in humans; t = 0.42 years is a random variable with a negative binomial distribution. A formula based on the expectation and variance of this random variable yields a moment-based estimate of a that is insensitive to the progressive reduction in oocyte numbers due to their utilization and apoptosis at later stages of life. In addition, we describe an algorithm for computing the maximum likelihood estimation of the FGC population size (a, as well as the rates of oogonial division and loss to apoptosis. Utilizing both of these approaches to evaluate available oocyte-counting data, we have obtained an estimate of a = 2 – 3 for Homo sapiens. Conclusion The estimated number of founding germ cells in humans corresponds well with values previously derived from chimerical or mosaic mouse data. These findings suggest that the large variation in oocyte numbers between individual women is consistent with a smaller founding germ cell population size than has been estimated by cytological analyses.

    Full Text Available Pathogens of Phytophthora genus are common not only in forest nurseries and stands, but also in water courses. Species of Phytophthora spread with plants for plantings (and soil attached to them and with water courses as well, attacking the plants growing in riparian ecosystems. Several specialized organisms damaging only one tree species were identified like P. alni on alders or P. quercina on oaks. Some Phytophthora species can develop on several hosts like P. plurivora and P. cactorum on oaks, beeches, alders, ashes and horse chestnuts. Other oomycetes like P. gallica species was found for the first time in Poland in water used for plant watering in forest nursery. Species P. lacustris and P. gonapodyides were found in superficial water. Phytophthora species P. polonica was identified in the declining alder stands for the first time in the world, and P. taxon hungarica and P. megasperma were found in the rhizosphere of seriously damaged ash stands for the first time in Poland. The most often isolated species were P. plurivora (clade 2 with frequency 37% and P. lacustris with frequency 33% (clade 6. The best represented clade 6 revealed the occurrence of 6 species: P. gonapodyides, P. lacustris, P. megasperma, P. sp. raspberry, P. taxon hungarica and P. taxon oak soil.

    When estimating the time since death or manner of death, the identification and the pathological evaluations of a body are generally impeded by post mortem changes. Research and case studies help experts to achieve a more accurate diagnosis, but at present there is scant literature covering topics concerning forensic science and decompositional processes in aquatic environments. The two case studies presented each involve a decomposed body found in a unique aquatic environment; namely wells containing ground water. In Case 1 an entomologist attended the scene and in Case 2 an entomologist was only involved after 20 months when it was decided that the insect evidence collected at the second autopsy may be useful in determining a time frame. The first case highlights the problems associated with body retrieval from aquatic environments as the body was removed it dismembered. Fortunately, the well was able to be drained, so much of the insect evidence was retrieved. In the second case the body was found dismembered but the entomological evidence was overlooked and lost. During the second autopsy insects were found, collected, and sent to an entomologist to help clarify the post mortem interval.

    By combining the modified conformal-evaporated-film-by-rotation (M-CEFR) technique with nickel electroforming, we have produced master negatives of nonplanar biotemplates. An approximately 250-nm-thick conformal coating of nanocrystaline nickel is deposited on a surface structure of interest found in class Insecta, and the coating is then reinforced with a roughly 60-μm-thick structural layer of nickel by electroforming. This structural layer endows the M-CEFR coating with the mechanical robustness necessary for casting or stamping multiple polymer replicas of the biotemplate. We have made master negatives of blowfly corneas, beetle elytrons, and butterfly wings.

    1997-01-01

    The aerobic microbial degradation of 21 condensed thiophenes found in petroleum or synthetic fuels have been studied, motivated by recent research which showed that resistance to biodegradation increases with increasing methyl-substitution. The specific objective was to identify metabolites in pure cultures of aromatic hydrocarbon-degrading Pseudomonas spp. incubated in mineral medium in the presence of an aromatic growth substrate and a condensed thiophene. Over 80 metabolites of the condensed thiophenes were identified using gas chromatography analysis with an atomic emission detector. Among the metabolites identified were sulfoxides, sulfones, hydroxy- and carboxyl-substituted benzothiophenes, hydroxy-substituted dibenzothiophenes, substituted benzothiophene-2,3-diones, and 3-hydroxy-2-formylbenzothiophenes

    Full Text Available This paper presents the results of observation of mould growth in laboratory colonies of termites. It also attempts to determine the species of mould fungi present in the research laboratory and the main colonies and their entomopathogenic for the termites. The following four species were found in test termite colonies: Trichoderme viride, Mucor himeralis, Rhizopus nigricans, Aspergillus sp., Aspergillus flavus, Alternaria sp., Penicylium verucosum and Fusarium sp. were recognisable in test colonies with domestic and exotic wood. Morphological observations of the fungi were carried out using a microscope with a 40x magnification. The growth of mould fungi in test containers caused death of whole termite colonies.

    2017-08-01

    Full Text Available Genetic mutations contribute to the etiology of autism spectrum disorder (ASD, a common, heterogeneous neurodevelopmental disorder characterized by impairments in social interaction, communication, and repetitive and restricted patterns of behavior. Since neuroligin3 (NLGN3, a cell adhesion molecule at the neuronal synapse, was first identified as a risk gene for ASD, several additional variants in NLGN3 and NLGN4 were found in ASD patients. Moreover, synaptopathies are now known to cause several neuropsychiatric disorders including ASD. In humans, NLGNs consist of five family members, and neuroligin1 (NLGN1 is a major component forming a complex on excitatory glutamatergic synapses. However, the significance of NLGN1 in neuropsychiatric disorders remains unknown. Here, we systematically examine five missense variants of NLGN1 that were detected in ASD patients, and show molecular and cellular alterations caused by these variants. We show that a novel NLGN1 Pro89Leu (P89L missense variant found in two ASD siblings leads to changes in cellular localization, protein degradation, and to the impairment of spine formation. Furthermore, we generated the knock-in P89L mice, and we show that the P89L heterozygote mice display abnormal social behavior, a core feature of ASD. These results, for the first time, implicate rare variants in NLGN1 as functionally significant and support that the NLGN synaptic pathway is of importance in the etiology of neuropsychiatric disorders.

    The Austral archipelago, on the western side of the South Pacific superswell, is composed of several volcanic chains, corresponding to distinct events from 35 Ma to the present, and lies on oceanic crust created between 60 and 85 Ma. In 1982, Turner and Jarrard proposed that the two distinct volcanic stages found on Rurutu Island and dated as 12 Ma and 1 Ma could be due to two different hotspots, but no evidence of any recent aerial or submarine volcanic source has ever been found. In July 1999, expedition ZEPOLYF2 aboard the R/V L'Atalante conducted a geophysical survey of the northern part of the Austral volcanic archipelago. Thirty seamounts were mapped for the first time, including a very shallow one (French Navy ship that discovered its summit in 1993, is the missing hotspot in the Cook-Austral history. This interpretation adds a new hotspot to the already complicated geologic history of this region. We suggest that several hotspots have been active simultaneously on a region of the seafloor that does not exceed 2000 km in diameter and that each of them had a short lifetime (<20 m.y.). These short-lived and closely spaced hotspots cannot be the result of discrete deep-mantle plumes and are likely due to more local upwelling in the upper mantle strongly influenced by weaknesses in the lithosphere.

    2015-09-03

    Using available reports, a checklist of the recorded helminth parasites of wild mammals from Patagonia was generated. Records of parasites found in Patagonia were included, together with records from mammals in áreas outside of Patagonia but whose range extends into Patagonia. Information about the host, localities, and references were also included. A total of 1323 records (224 Cestoda, 167 Trematoda, 894 Nematoda, 34 Acanthocephala, and 4 Pentastomida) belonging to 452 helminth species (77 Cestoda, 76 Trematoda, 277 Nematoda, 21 Acanthocephala, and 1 Pentastomida) found in 57 native mammals (22 Rodentia, 4 Didelphimorphia 1 Microbiotheria, 7 Chiroptera, 5 Cingulata, and 13 Carnivora) were listed. However, only 10.6 % of the reports were conducted on samples from Patagonia and corresponded to 25% of mammals in the region. In addition, many studies were made on a few species and, for example, 52% corresponded to studies made on Lama guanicoe. This suggests the need to increase efforts to know the parasitic fauna in a peculiar region as is the Patagonia. This is the first compilation of the helminth parasites of mammals in Argentine Patagonia and is important for parasitological and paleoparasitological studies.

    2009-12-01

    Sennoside A and B were detected in 21 commercial health tea products surveyed in 2000-2007, but there were 8 products in which the leaves could not be identified as senna because the leaves had become discolored. The results of assay of sennoside levels and TLC chromatograms suggested that processed senna had been used in these products. Next, with reference to tea and health tea manufacturing methods, pharmaceutical senna was roasted or wet-processed experimentally. The results indicated that the discolored leaves contained in commercial health tea were most likely derived from senna leaves. Moreover, sennosides in medicinal doses were detected in some processed senna samples, and were determined to have a cathartic action in mice. Based on morphological confirmation and the results of component analysis, including sennoside, the discolored leaves found in commercial health teas were therefore determined to be senna leaves. There may be possible health risks, including diarrhea.

    2013-02-01

    On 31 August 2012 a magnitude 7.6 earthquake ruptured deep beneath the sea floor of the Philippine Trench, a powerful intraplate earthquake centered seaward of the plate boundary. In the wake of the main shock, sensors detected a flurry of aftershocks, counting 110 in total. Drawing on seismic wave observations and rupture mechanisms calculated for the aftershocks, Ye et al. found that many were located near the epicenter of the main intraplate quake but at shallower depth; all involved normal faulting. Some shallow thrusting aftershocks were located farther to the west, centered within the potentially dangerous megathrust fault formed by the subduction of the Philippine Sea plate beneath the Philippine microplate, the piece of crust housing the Philippine Islands.

    This article provided details of an ancient reptile that once swam in ancient seas near the present location of Alberta's oil sands region. The plesiosaur has now been named after a curator at the Royal Tyrrell Museum who was also a renowned paleontologist. The nearly complete remains of one of the oldest plesiosaur fossils were recovered at a Syncrude Canada mine near Fort McMurray in 1994. Paleontologists from the University of Calgary have recently published a paper on the prehistoric aquatic predator in a German research journal. A plaster cast of the plesiosaur found at the Syncrude site is now on display at the Oil Sands Discovery Centre in Fort McMurray. 1 fig.

  2. Proposal for founding mistrustful quantum cryptography on coin tossing

    International Nuclear Information System (INIS)

    Kent, Adrian

    2003-01-01

    A significant branch of classical cryptography deals with the problems which arise when mistrustful parties need to generate, process, or exchange information. As Kilian showed a while ago, mistrustful classical cryptography can be founded on a single protocol, oblivious transfer, from which general secure multiparty computations can be built. The scope of mistrustful quantum cryptography is limited by no-go theorems, which rule out, inter alia, unconditionally secure quantum protocols for oblivious transfer or general secure two-party computations. These theorems apply even to protocols which take relativistic signaling constraints into account. The best that can be hoped for, in general, are quantum protocols which are computationally secure against quantum attack. Here a method is described for building a classically certified bit commitment, and hence every other mistrustful cryptographic task, from a secure coin-tossing protocol. No security proof is attempted, but reasons are sketched why these protocols might resist quantum computational attack

  3. Survey of Legionella Species Found in Thai Soil

    Full Text Available Members of the Gram-negative genus Legionella are typically found in freshwater environments, with the exception of L. longbeachae, which is present in composts and potting mixes. When contaminated aerosols are inhaled, legionellosis may result, typically as either the more serious pneumonia Legionnaires’ disease or the less severe flu-like illness Pontiac fever. It is presumed that all species of the genus Legionella are capable of causing disease in humans. As a followup to a prior clinical study of legionellosis in rural Thailand, indigenous soil samples were collected proximal to cases’ homes and workplaces and tested for the presence of legionellae by culture. We obtained 115 isolates from 22/39 soil samples and used sequence-based methods to identify 12 known species of Legionella represented by 87 isolates.

  4. 100 New Impact Crater Sites Found on Mars

    Science.gov (United States)

    Kennedy, M. R.; Malin, M. C.

    2009-12-01

    Recent observations constrain the formation of 100 new impact sites on Mars over the past decade; 19 of these were found using the Mars Global Surveyor Mars Orbiter Camera (MOC), and the other 81 have been identified since 2006 using the Mars Reconnaissance Orbiter Context Camera (CTX). Every 6 meter/pixel CTX image is examined upon receipt and, where they overlap images of 0.3-240 m/pixel scale acquired by the same or other Mars-orbiting spacecraft, we look for features that may have changed. New impact sites are initially identified by the presence of a new dark spot or cluster of dark spots in a CTX image. Such spots may be new impact craters, or result from the effect of impact blasts on the dusty surface. In some (generally rare) cases, the crater is sufficiently large to be resolved in the CTX image. In most cases, however, the crater(s) cannot be seen. These are tentatively designated as “candidate” new impact sites, and the CTX team then creates an opportunity for the MRO spacecraft to point its cameras off-nadir and requests that the High Resolution Imaging Science Experiment (HiRISE) team obtain an image of ~0.3 m/pixel to confirm whether a crater or crater cluster is present. It is clear even from cursory examination that the CTX observations are areographically biased to dusty, higher albedo areas on Mars. All but 3 of the 100 new impact sites occur on surfaces with Lambert albedo values in excess of 23.5%. Our initial study of MOC images greatly benefited from the initial global observations made in one month in 1999, creating a baseline date from which we could start counting new craters. The global coverage by MRO Mars Color Imager is more than a factor of 4 poorer in resolution than the MOC Wide Angle camera and does not offer the opportunity for global analysis. Instead, we must rely on partial global coverage and global coverage that has taken years to accumulate; thus we can only treat impact rates statistically. We subdivide the total data

  5. A system view of the No Fault Found (NFF) phenomenon

    2007-01-01

    When a unit is tested outside a technical system, it has normally been removed due to a fault. However, in some cases the external test may not discover any fault and a No Fault Found (NFF) event may occur. The NFF phenomenon is a major problem when dealing with complex technical systems, and its consequences may be manifested in decreased safety and dependability and increased life cycle costs. There are multiple interacting causes of NFF, demanding tough requirements for successful solutions. The purpose of this paper is to describe the phenomenon of NFF and to highlight possible improvements for the prevention of causes of NFF and the reduction of its consequences. The study was performed as an explorative literature study, and the analysis was based on a holistic system view. The identified causes and solutions are related to life cycle stages, availability performance factors, and system stakeholders

    The settlement of Madagascar is one of the most unusual, and least understood, episodes in human prehistory. Madagascar was one of the last landmasses to be reached by people, and despite the island's location just off the east coast of Africa, evidence from genetics, language and culture all attests that it was settled jointly by Africans, and more surprisingly, Indonesians. Nevertheless, extremely little is known about the settlement process itself. Here, we report broad geographical screening of Malagasy and Indonesian genetic variation, from which we infer a statistically robust coalescent model of the island's initial settlement. Maximum-likelihood estimates favour a scenario in which Madagascar was settled approximately 1200 years ago by a very small group of women (approx. 30), most of Indonesian descent (approx. 93%). This highly restricted founding population raises the possibility that Madagascar was settled not as a large-scale planned colonization event from Indonesia, but rather through a small, perhaps even unintended, transoceanic crossing.

    Edible insects are gaining more and more attention as a sustainable source of animal protein for food and feed in the future. In Belgium, some insect products can be found on the market, and consumers are sourcing fresh insects from fishing stores or towards traditional markets to find exotic insects that are illegal and not sanitarily controlled. From this perspective, this study aims to characterize the microbial load of edible insects found in Belgium (i.e., fresh mealworms and house crickets from European farms and smoked termites and caterpillars from a traditional Congolese market) and to evaluate the efficiency of different processing methods (blanching for all species and freeze-drying and sterilization for European species) in reducing microorganism counts. All untreated insect samples had a total aerobic count higher than the limit for fresh minced meat (6.7 log cfu/g). Nevertheless, a species-dependent blanching step has led to a reduction of the total aerobic count under this limit, except for one caterpillar species. Freeze-drying and sterilization treatments on European species were also effective in reducing the total aerobic count. Yeast and mold counts for untreated insects were above the Good Manufacturing Practice limits for raw meat, but all treatments attained a reduction of these microorganisms under this limit. These results confirmed that fresh insects, but also smoked insects from non-European trades, need a cooking step (at least composed of a first blanching step) before consumption. Therefore, blanching timing for each studied insect species is proposed and discussed.

  9. Found: The Original 1945 Records of Australian Radio Astronomy

    Goss, Miller; Ekers, Ron; Sim, Helen

    2015-08-01

    In July 2014, we found the original records of the first published Australian radio astronomy observations. These were obtained by Joseph L. Pawsey and Ruby Payne-Scott in early October 1945. The observations gave strong evidence of a million degree corona as well as frequent radio bursts.These observations followed earlier detections of the radio sun by Stanley Hey, George Southworth, Grote Reber and Elizabeth Alexander. The latter observations (the "Norfolk Island Effect" of March 1945) were the immediate motivation for the campaign carried out by Pawsey and Payne-Scott.These observations formed the basis for a number of pioneering publications: the 9 February 1946 Nature paper of Pawsey, Payne-Scott and McCready which was submitted on the last date on which data was obtained on 23 October 1945, the major publication of the initial Australian radio solar publication in the Proceedings of the Royal Society of London in August 1947 and Pawsey's presentation of the radio properties of the million degree corona in the Nature of 2 November 1946. Contemporaneously with these publications, D. F.Martyn was involved in an independent theoretical study of the properties of the solar corona.(Ginzburg and Shklovsky were also involved in this era in a study of the properties of the corona.) The back-to-back Martyn and Pawsey Nature papers were the first that described the radio properties of the hot corona, due to free-free emission. The division of the observed emission into "bursting" and "quiet" modes was challenging for the novice radio astronomers.These historical records had been recognized by Paul Wild in 1968, who instructed the CSIRO Division of Radiophysics secretary to E.("Taffy") G. Bowen, Ms. Sally Atkinson, to submit these to the Australian Academy of Science. Wild characterized these documents as "of considerable historical interest". Apparently the transmission of the documents was not done; a thorough search of the Australian Academy Library in August 2014

    2017-01-01

    Background: Although prescriptions are dispensed at discretion of medical professionals, many pharmaceutical companies use direct-to-consumer (DTC) advertising to increase sales. Over-the-counter (OTC) medications are similarly marketed. Methods: We examined the content of advertisements in 38 issues of 9 popular US women's fashion magazines. We evaluated target audience, health condition, product availability, message appeal, target to females, and mention of potential side effects and benefits. Results: Sixty total medication advertisements were identified, 58.3% (95% CI: 45.8, 70.8) for prescription products. In magazines targeted to non-Hispanic Whites, >65% of advertisements were for OTC medications whereas 80% (95% CI: 66.7, 94.5) of advertisements found in Black/Latina magazines were for prescription medications. The rational appeal was used most commonly in non-Hispanic White magazines (75.9%; 95% CI: 60.3, 91.5). Emotional appeal was featured more often in prescription advertisements magazines (60.0; 95% CI:43.8, 76.2) compared to OTC (8.0; 95% CI: -2.6, 18.6). Conclusion: Although emotional appeal may be effective for selling medication to women, it often does not completely inform consumers of potential risks.

    2017-11-13

    Cultivable microbiota presents in a coffee semi-dry processing wastewater treatment plant (WTP) was identified. Thirty-two operational taxonomic units (OTUs) were detected, these being 16 bacteria, 11 yeasts and 4 filamentous fungi. Bacteria dominated the microbial population (11.61 log CFU mL - 1 ), and presented the highest total diversity index when observed in the WTP aerobic stage (Shannon = 1.94 and Simpson = 0.81). The most frequent bacterial species were Enterobacter asburiae, Sphingobacterium griseoflavum, Chryseobacterium bovis, Serratia marcescens, Corynebacterium flavescens, Acetobacter orientalis and Acetobacter indonesiensis; these showed the largest total bacteria populations in the WTP, with approximately 10 log CFU mL - 1 . Yeasts were present at 7 log CFU mL - 1 of viable cells, with Hanseniaspora uvarum, Wickerhamomyces anomalus, Torulaspora delbrueckii, Saturnispora gosingensis, and Kazachstania gamospora being the prevalent species. Filamentous fungi were found at 6 log CFU mL - 1 , with Fusarium oxysporum the most populous species. The identified species have the potential to act as a biological treatment in the WTP, and the application of them for this purpose must be better studied.

  14. Nurse executive transformational leadership found in participative organizations.

    Dunham-Taylor, J

    2000-05-01

    The study examined a national sample of 396 randomly selected hospital nurse executives to explore transformational leadership, stage of power, and organizational climate. Results from a few nurse executive studies have found nurse executives were transformational leaders. As executives were more transformational, they achieved better staff satisfaction and higher work group effectiveness. This study integrates Bass' transformational leadership model with Hagberg's power stage theory and Likert's organizational climate theory. Nurse executives (396) and staff reporting to them (1,115) rated the nurse executives' leadership style, staff extra effort, staff satisfaction, and work group effectiveness using Bass and Avolio's Multifactor Leadership Questionnaire. Executives' bosses (360) rated executive work group effectiveness. Executives completed Hagberg's Personal Power Profile and ranked their organizational climate using Likert's Profile of Organizational Characteristics. Nurse executives used transformational leadership fairly often; achieved fairly satisfied staff levels; were very effective according to bosses; were most likely at stage 3 (power by achievement) or stage 4 (power by reflection); and rated their hospital as a Likert System 3 Consultative Organization. Staff satisfaction and work group effectiveness decreased as nurse executives were more transactional. Higher transformational scores tended to occur with higher educational degrees and within more participative organizations. Transformational qualities can be enhanced by further education, by achieving higher power stages, and by being within more participative organizations.

    The co-authors of this paper hereby state their intention to work together to launch the Genomic Observatories Network (GOs Network) for which this document will serve as its Founding Charter. We define a Genomic Observatory as an ecosystem and/or site subject to long-term scientific research, including (but not limited to) the sustained study of genomic biodiversity from single-celled microbes to multicellular organisms.An international group of 64 scientists first published the call for a global network of Genomic Observatories in January 2012. The vision for such a network was expanded in a subsequent paper and developed over a series of meetings in Bremen (Germany), Shenzhen (China), Moorea (French Polynesia), Oxford (UK), Pacific Grove (California, USA), Washington (DC, USA), and London (UK). While this community-building process continues, here we express our mutual intent to establish the GOs Network formally, and to describe our shared vision for its future. The views expressed here are ours alone as individual scientists, and do not necessarily represent those of the institutions with which we are affiliated.

    Although in a previous study we showed that caffeine and theobromine were the main psychopharmacologically active constituents in a 50-g bar of chocolate, mere activity does not guarantee a role in our liking for the food. Our aim was to see if liking for a drink repeatedly paired with these amounts of caffeine and theobromine would increase compared to a placebo-paired drink. Participants (n=64) consumed a 'novel' drink + treatment capsule on six non-consecutive mornings using a double-blind, placebo-controlled independent-sample design. Aspects of liking and intensity of various sensory descriptors for these drinks were measured at every drink collection. Treatment capsules contained either an ecologically relevant dose combination of 19-mg caffeine and 250-mg theobromine or a placebo. Liking for the drink paired with the methylxanthine-containing capsules increased over time compared to the placebo-paired drink. This highly significant effect was confirmed by subjective, retrospective changes in liking for the drink. Methylxanthines in amounts found in 50-g chocolate may well contribute to our liking for chocolate, especially to the more acquired taste for dark chocolate.

    Err. Wait. Please no! USB sticks are not innocent little things. They can quickly mutate into malicious nasty beasts! Just in the recent past, at least two physics experiments were suffering as their control and data acquisition PCs, respectively, were infected by USB sticks holding malicious code. A bit longer ago, a series of laptops were infected at a 2008 computing conference as an infected USB stick made its tour around. Bad luck for those who ran a Windows operating system and inserted that stick…   So, you found a USB stick in the cafeteria? Take care. If this were a lollipop, you wouldn’t just pick it up and lick it, would you? So beware of USB sticks whose origin or previous usage you don’t know. They might infect your PC once plugged in. In order to be on the safe side, accept and share only USB sticks whose owner you trust. Run up-to-date anti-virus software on your PC, make sure that its operating system is patched...

    This study describes the morphology of the nematode cysts and larvae found in Achatina fulica (giant African snail) in Brazil. Sixty snails were collected in Mesquita, Rio de Janeiro State. Fourteen of the snails were naturally infected. The cysts were spherical, pink colored and measured 0.97 to 1.57 mm in diameter. In the majority of cases they had a single larvae involved in amorphous material. A total of 222 encysted larvae were recovered. Of these, 30 were utilized in the morphological study. The length of the larvae varied from 2.57 to 5.8 mm and they were classified as small--up to 3.5 mm; medium--from 3.53 to 4.5 mm; and large--greater than 4.52 mm. The average length of the larvae in the three groups was 2.85, 3.87 and 5.23 mm, respectively. The larval cuticle was white, shiny and transversally striated until the posterior end of the body. At the anterior end there is a mouth with three lips, with amphids and papillae, followed by a muscular esophagus with average length of 0.61 mm, terminating in an esophageal bulb and having a nerve ring in the middle third of the esophagus, and an intestine with an opening near the posterior end. The tail begins from this opening and has two types of ends: short and abrupt or long and gradually tapering. The difference in the tail end can suggest sexual dimorphism, although no primordial reproductive structures were observed. These characteristics were not sufficient to identify the larvae, so there is a need for further study.

    Full Text Available There is currently no consensus on the treatment sequence in chronic obstructive pulmonary disease (COPD, although it is recognized that early diagnosis is of paramount importance to start treatment in the early stages of the disease. Although it is fairly consensual that initial treatment should be with an inhaled short-acting beta agonist, a short-acting muscarinic antagonist, a long-acting beta-agonist or a long-acting muscarinic antagonist. As the disease progresses, several therapeutic options are available, and which to choose at each disease stage remains controversial. When and in which patients to use dual bronchodilation? When to use inhaled corticosteroids? And triple therapy? Are the existing non-inhaled therapies, such as mucolytic agents, antibiotics, phosphodiesterase-4 inhibitors, methylxanthines and immunostimulating agents, useful? If so, which patients would benefit? Should co-morbitities be taken into account when choosing COPD therapy for a patient?This paper reviews current guidelines and available evidence and proposes a therapeutic scheme for COPD patients. We also propose a treatment algorithm in the hope that it will help physicians to decide the best approach for their patients. The authors conclude that, at present, a full consensus on optimal treatment sequence in COPD cannot be found, mainly due to disease heterogeneity and lack of biomarkers to guide treatment. For the time being, and although some therapeutic approaches are consensual, treatment of COPD should be patient-oriented.

    Full Text Available 【Abstract】Objective: Yoga is becoming more and more popular in the female society while the concomitant sports injury is seldom mentioned. Many clinicians have noted that yoga may result in knee problems, which though requires more researches to corroborate. This investigation was conducted to ascertain the relationship between yoga and meniscus injury as well as the extent of impairment ac-cording to variant yoga practice periods. Methods: Totally 819 women aged 20-49 years who practiced yoga or other popular sports including badminton, jogging, climbing hills, etc for at least one hour per day were selected to participate in this research. These subjects were required to complete a questionnaire and receive relevant physical examination. Magnetic resonance (MR scan of the knee was recommended for the suspicious subjects for ultimate diagnosis. The subject with abnormal meniscus MR signals was defined as a case and matched with two con-trols in terms of age and body mass index (BMI. Altogether there were 273 cases and 546 controls. The nested case-control model was adopted to assess the risk of meniscus injury between variant exposures in practicing yoga and several other popular sports. Moreover, the 181 yoga sub-jects were subdivided into three groups according to differ-ent exercise durations, followed by further analysis with the variables of age, BMI and Lysholm score. Results: Yoga was found associated with a higher risk (P=0.008, OR=1.621 of meniscus injury compared with badminton, jogging and climbing hills. The three yoga sub-groups showed statistical difference between each other in terms of Lysholm score (P=0.027 and BMI (P=0.003. The subjects with longer-term yoga practice had lighter weight but lower Lysholm scores. Conclusions: Yoga perhaps exerts destructive impact on the meniscus for Chinese women, yet it needs further verifications. Furthermore, the female yoga players with longer exercise duration are more susceptible to

  1. Possible Analog for Early Solar System Disk Found

    Science.gov (United States)

    1998-10-01

    SOCORRO, NM -- The smallest protoplanetary disk ever seen rotating around a young star has been detected by an international team of astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope. If confirmed, this result could provide an "ideal laboratory" for studying potential planet-forming disks of a size similar to the one that formed our Solar System. The researchers used the VLA to image the core of an object known as NGC 2071, some 1300 light years from Earth. The team of astronomers was able to measure the rotation of a disk seen around a young star by tracking water masers - clusters of super-heated molecules that amplify radio emission -- within it. This is the first direct evidence of such motion in a protoplanetary disk. "This result is exciting because only through understanding protoplanetary disks can scientists answer the question of how easy - or hard - it is to create planets," said Jose M. Torrelles of the Institute for Astrophysics of Andalucia in Granada, Spain, leader of the research team. "Other protoplanetary disks have been found, but the system in NGC 2071 is the first that may be comparable to the disk that created our own Solar System. Its size is similar to the orbit of the planet Neptune around our Sun." "Because there is very little matter in one of these protoplanetary disks -- typically less than one hundredth the mass of our Sun -- they are extremely difficult to detect and study" said Paul Ho of the Harvard-Smithsonian Center for Astrophysics and another team member. "We needed the highest possible resolution of the VLA to do this work." The VLA is an array of twenty-seven radio dishes, each 25 meters in diameter, located outside of Socorro. The individual antennas can be moved along tracks to change the array's alignment. The work on NGC 2071 was done when the array was stretched out to over 36 kilometers, thus providing the extremely high resolution necessary to image the system. This disk

    A study of fatty-acid ratios in French fries has proved to be an excellent choice for an entry-level research class. This research develops reasoning skills and involves the subject of breast cancer, a major concern of American society. Analysis of tumor samples removed from women with breast cancer revealed high ratios of linoleic to linolenic acid, suggesting a link between the accelerated growth of breast tumors and the combination of these two fatty acids. When the ratio of linoleic to linolenic acid was approximately 9 to 1, accelerated growth was observed. Since these fatty acids are found in cooking oils, Wichita Collegiate students, under the guidance of their chemistry teacher, decided that an investigation of the ratios of these two fatty acids should be conducted. A research class was structured using a gas chromatograph for the analysis. Separation of linoleic from linolenic acid was successfully accomplished. The students experienced inductive experimental research chemistry as it applies to everyday life. The structure of this research class can serve as a model for high school and undergraduate college research curricula.

    2016-06-01

    This study tested the association between school-wide measures of an authoritative school climate and high school dropout rates in a statewide sample of 315 high schools. Regression models at the school level of analysis used teacher and student measures of disciplinary structure, student support, and academic expectations to predict overall high school dropout rates. Analyses controlled for school demographics of school enrollment size, percentage of low-income students, percentage of minority students, and urbanicity. Consistent with authoritative school climate theory, moderation analyses found that when students perceive their teachers as supportive, high academic expectations are associated with lower dropout rates.

    Morberg, Siv; Lagerström, Monica; Dellve, Lotta

    2009-11-01

    To gain a deeper understanding of how Swedish head school nurses perceive their leadership in developing school health care. A well-functioning school health care is important for promoting the health of children and young people. Constructivist-grounded theory was used to analyse 11 individual interviews with nine head school nurses. Head school nurses strive to find a balance between what they experience as vague formal goals and strong informal goals which leads to creating local goals in order to develop school health care. The head school nurse's job is experienced as a divided and pioneering job in which there is uncertainty about the leadership role. They provide individual support to school nurses, are the link between school nurses and decision makers and highlight the importance of school nurses' work to organizational leaders. This study shows that school health care needs to be founded on evidence-based methods. Therefore, a structured plan for education and training in school health care management, based on research and in cooperation with the academic world, would develop the head school nurses' profession, strengthen the position of school health care and advance the school nurses' work.

    2012-07-01

    Full Text Available Different human languages look different from other human languages. To use a term from the computer industry, each human language has its own “look and feel”. European English speakers can easily recognise a phrase such as “Comment allez-vous?” as being written in French while the phrase “¿Habla usted español?” is written in Spanish. Each language has its own letter frequencies, word frequencies and other identifiers. This paper describes key identifiers in MXit lingo as found in Dr Math conversations. MXit is a mobile instant messaging system which originated in South Africa and is expanding to other countries. Dr Math is a mobile tutoring system which uses MXit as a communication protocol. Primary and secondary school pupils can receive help with the mathematics homework using the Dr Math tutoring system. The pupils use MXit on their cell phones and the tutors use traditional Internet workstations. After exploring how MXit lingo is written, this paper will briefly explore why MXit lingo is written the way it is. By identifying and describing the orthographic conventions visible in the spelling of MXit lingo, although with some theoretical support, insight into the purposeful and functional nature of written, mobile communication will be revealed. In highlighting spelling that is influenced by Black South African English, an attempt will be made to contribute to the empirical development of a field of study that explores the construction of words used in South African mobile communication.

    Full Text Available Outdoor school is a stable element of Czech educational system. However,many changes have occurred during the last twenty years in the purposes of outdoorschools and in their organization. The article presents various school statistics andresults of research which included questionnaire survey in elementary schools in Pragueand a case study of two classes. The study found that the outdoor school programmesare getting shorter, budgets for outdoor schools are reduced, and prices of outdoorschool programmes for parents are increasing. Because of high prices, almost 20 % ofpupils cannot attend outdoor schools. Nevertheless, according to teachers, pupils andparents, the main purpose of outdoor school programmes is to create a better socialclimate in peer groups. Because of high rates of absence, this goal is partly invalid.Another purpose should be that teachers and children get to know each other better.This goal is invalid as well because many schools hire commercial agencies which limitsthe time that pupils and teachers spend together.

    School achievement gaps and school failure are problematic issues in Latin America, and are mainly explained by the socio-economic status (SES) of the students. What schools can do to improve school achievement and reduce school failure is a critical issue, both for school management and teacher training. In this study, we present the association of individual and school-related socio-emotional variables with school achievement and performance, controlling for the effects of SES. A probabilistic sample of 4,964 students, drawn from 191 schools enrolled in year 10 in urban areas of Chile, answered questionnaires assessing subjective wellbeing, social wellbeing in school, school climate, school social wellbeing and students’ perceptions of teachers’ wellbeing. Using structural equation modeling, and controlling for SES, we modeled subjective wellbeing as a mediator of the relationship between school-related variables, such as school climate and perception of teacher’s wellbeing, and (a) school achievement, and (b) school performance. School achievement was computed as a product of (a) the probability of passing the school year, and (b) the percentage of yearly attendance at school. Data on school achievement was drawn from administrative registries from the Chilean Ministry of Education. School performance was computed as the estimated grade point average (GPA) at the end of the school year, based on the students’ previous 5-year GPAs, and was also obtained through administrative data of the last 5 years. Findings reveal the mediating role of subjective wellbeing in the relationship between school-related evaluations (students’ social wellbeing at school, their perception of teachers’ wellbeing and school climate) and school achievement. For school achievement, two variables were mediated (students’ social wellbeing at school and school climate). However, for school performance, no significant mediations were found. We conclude that, on the one hand

School achievement was computed as a product of (a the probability of passing the school year, and (b the percentage of yearly attendance at school. Data on school achievement was drawn from administrative registries from the Chilean Ministry of Education. School performance was computed as the estimated grade point average (GPA at the end of the school year, based on the students’ previous 5-year GPAs, and was also obtained through administrative data of the last 5 years. Findings reveal the mediating role of subjective wellbeing in the relationship between school-related evaluations (students’ social wellbeing at school, their perception of teachers’ wellbeing and school climate and school achievement. For school achievement, two variables were mediated (students’ social wellbeing at school and school climate. However, for school performance, no significant mediations were found. We conclude that, on the

    Full Text Available Entrepreneurial leadership, as a distinctive type of leadership required for dealing with challenges and crises of current organizational settings, has increasingly been applied to improve school performance. However, there is limited research on the impact ofschool leaders' entrepreneurial leadership practices on school innovativeness. The main purpose of this study is to identify the relationship between principals' entrepreneurial leadership practices and school innovativeness through the teachers' perspectives. The participants included 294 Malaysian secondary school teachers in Selangor, Malaysia. A questionnaire containing 64 items (50 items on school principals' entrepreneurial leadership practices and 14 items on school innovativeness was utilized. An analysis of the data indicates that teachers perceive entrepreneurial leadership as highly important for school principals. However, the principals practise it moderately. Furthermore, this study found a significant correlation between teachers' perceptions of school principals' entrepreneurial leadership practices and school in-novativeness. Implications of the findings for developing school principals' entrepreneurial leadership and school innovativeness are discussed.

    1999-11-01

    Associations between psychosomatic symptoms and school-induced stress, and personal and social resources were analyzed among 862 Norwegian adolescents ages 13-15 years participating in the WHO project, "Health Promoting Schools." Stress-related factors were represented by the average of scores of 3-12 items. Both in combined and separate analyses of each psychosomatic symptom, increasing school distress, the most direct measure of stress experience, was associated with increased risk. A similar relationship was found with school alienation, though not significant for all symptoms. Social support from the teacher decreased the risk among girls, whereas social support from other pupils reduced the risk among both genders, but in particular among boys. No consistent associations were seen between psychosomatic complaints and general or school-related self-efficacy or decision control. In some analyses, however, these factors seemed to modify the association with school distress or school alienation.

    2014-01-01

    Full Text Available Background: Although injuries at school are an important issue in public health, environmental factors in schools and school yards have seldom been the focus of school injury research. The goal of our investigation was to examine the effect of environmental factors on school injuries. Methods: Nine comprehensive Finnish schools registered school injuries over a period of two school years. Injuries were classified as being associated with environmental factors, suspected environmental factors, and others. The consensus between two independent classifiers was 81%. Results: A total of 722 injuries were classified. In 11.6% of these injuries, the physical environment factor was evident, and in 28.1% of the injuries, physical environment was suspected of being a contributory risk factor. Thus the physical environment of the school was a contributing factor in over a third (39.7% of injuries occurring in the school, on the school yard or during the journey to or from school. In this study, conducted in Finland, ice on the ground was mentioned most frequently as an environmental risk factor. Conclusions: In Finland, the Nordic weather conditions are not taken into account in the school yard and playground plans as they ought to from the safety point of view. An initiative has been launched on a mandatory wintertime master plan for every school yard.

    Peake, R.T.; Schmidt, A.; MacWaters, J.T.; Chmelynski, H.

    1990-01-01

    During the winter of 1989, Rn screening measurements were made in 130 schools distributed across the United States. The primary purpose of the paper is to identify schools suitable for a year-long follow-up study, the results of which will be used to update EPA's guidance for Rn testing in schools. The 130 schools were selected nonrandomly using school characteristics and accessibility in areas where there were known or suspected Rn problems in homes. Levels found in this screening study may indicate the potential for Rn problems in US schools. Over half of the 130 schools tested had at least one radon measurement ≥4 pCi/L, and nearly 20% of the 3028 rooms measured ≥4 pCi/L. The number of rooms ≥4 pCi/L is often three rooms or less. However, schools with more than five rooms ≥4 pCi/L are common in some areas. The data include schools that could be typical of much of the US school population as well as schools which exhibit extreme radon problems, such as those tested in Nashville, TN and Spokane, WA

    Directory of Open Access Journals (Sweden)

    Yeyep Natrio

    2018-04-01

    Full Text Available Phenomenon of using proverb in academic environment particularly school is usual right now. Not only using Indonesian proverb but also using English proverb, students are interested to apply them. The trend to use English as the L2 in presenting good philosophy of life is one method to help students to master and acquaintance with English. In term of English proverb, it is usually used to present condition of school environment, students, and the regulation of school which are managed systematically. Particularly, most of the English proverbs in SMAN 1 Lubuk Alung are applied to boost motivation of the students. In fact, there are some of them are misled in transferring the meaning from the real receptor language. The translation of the proverbs were dull and were not appropriate to English sense as receptor language. Learners are unaware of the pragmatic knowledge that a proverb has because they do not recognize the purpose of the communicative act that a proverb has socio-pragmatically. I conclude that the proverbs which were taken from Senior High School No. 1 Lubuk Alung, West Sumatera tends to the incorrect translation so that the students have a problem called pragmatic failure. The process of applying the English proverbs to represent the Indonesian proverbs is not suitable in the Receptor Language (RL, English. There is misleading of choosing word and also the arrangement/ structure of those words. The effort of delivering similar message in another language was failed since they did not know how to transfer knowledge about linguistic, cultural, and social information about the target language.

  20. Belongingness in Early Secondary School: Key Factors that Primary and Secondary Schools Need to Consider.

    Directory of Open Access Journals (Sweden)

    Sharmila Vaz

    Full Text Available It is unknown if, and how, students redefine their sense of school belongingness after negotiating the transition to secondary school. The current study used longitudinal data from 266 students with, and without, disabilities who negotiated the transition from 52 primary schools to 152 secondary schools. The study presents the 13 most significant personal student and contextual factors associated with belongingness in the first year of secondary school. Student perception of school belongingness was found to be stable across the transition. No variability in school belongingness due to gender, disability or household-socio-economic status (SES was noted. Primary school belongingness accounted for 22% of the variability in secondary school belongingness. Several personal student factors (competence, coping skills and school factors (low-level classroom task-goal orientation, which influenced belongingness in primary school, continued to influence belongingness in secondary school. In secondary school, effort-goal orientation of the student and perception of their school's tolerance to disability were each associated with perception of school belongingness. Family factors did not influence belongingness in secondary school. Findings of the current study highlight the need for primary schools to foster belongingness among their students at an early age, and transfer students' belongingness profiles as part of the hand-over documentation. Most of the factors that influenced school belongingness before and after the transition to secondary are amenable to change.

More recently, with the development of new technologies, our society has seen the cyber-bullying born. This new type of harassment "on-line" comes and intersects the harassment at school. After the description of a clinical situation, we describe the impact of this phenomenon on the different actors concerned, the lines for prevention and for appropriate support.

  3. Social regulation of maternal traits in nest-founding bumble bee (Bombus terrestris) queens.

    Woodard, S Hollis; Bloch, Guy; Band, Mark R; Robinson, Gene E

    2013-09-15

    During the nest-founding phase of the bumble bee colony cycle, queens undergo striking changes in maternal care behavior. Early in the founding phase, prior to the emergence of workers in the nest, queens are reproductive and also provision and feed their offspring. However, later in the founding phase, queens reduce their feeding of larvae and become specialized on reproduction. This transition is synchronized with the emergence of workers in the colony, who assume the task of feeding their siblings. Using a social manipulation experiment with the bumble bee Bombus terrestris, we tested the hypothesis that workers regulate the transition from feeding brood to specialization on reproduction in nest-founding bumble bee queens. Consistent with this hypothesis, we found that early-stage nest-founding queens with workers prematurely added to their nests reduce their brood-feeding behavior and increase egg laying, and likewise, late-stage nest-founding queens increase their brood-feeding behavior and decrease egg-laying when workers are removed from their nests. Further, brood-feeding and egg-laying behaviors were negatively correlated. We used Agilent microarrays designed from B. terrestris brain expressed sequenced tags (ESTs) to explore a second hypothesis, that workers alter brain gene expression in nest-founding queens. We found evidence that brain gene expression in nest-founding queens is altered by the presence of workers, with the effect being much stronger in late-stage founding queens. This study provides new insights into how the transition from feeding brood to specialization on reproduction in queen bumble bees is regulated during the nest initiation phase of the colony cycle.

    Full Text Available This study aimed at examining school administrators’ innovational leadership behaviors and the level of practicing these behaviors. The study was designed using the descriptive model since it aimed to identify school administrators’ innovative behaviors and approaches in school management. School Management Innovational Leadership Scale (SMILES developed (2016 by the researcher was used in the study as the data collection instrument. Data was collected from 111 school administrators and 346 teachers during the 2015-2016 academic teaching year. According to the research results, school administrators’ innovational leadership behaviors are collected under three factors; "Encouraging Innovation", "Pursuing Innovation", and "Implementing Innovation".It was found that school administrators mostly show the innovational leadership behaviors expressed in the three factors and in the total scale. It was expressed in the study that compared to females; males believe that school administrators show more innovational leadership behaviors. Also, compared to participants with graduate degrees, participants with undergraduate degrees believe that school administrators show more innovational leadership behaviors. At the same time, compared to teachers, school administrators believe that they show more innovational leadership behaviors.

  11. Nest Relocation and Colony Founding in the Australian Desert Ant, Melophorus bagoti Lubbock (Hymenoptera: Formicidae

    Directory of Open Access Journals (Sweden)

    Patrick Schultheiss

    2010-01-01

    Full Text Available Even after years of research on navigation in the Red Honey Ant, Melophorus bagoti, much of its life history remains elusive. Here, we present observations on nest relocation and the reproductive and founding stages of colonies. Nest relocation is possibly aided by trail laying behaviour, which is highly unusual for solitary foraging desert ants. Reproduction occurs in synchronised mating flights, which are probably triggered by rain. Queens may engage in multiple matings, and there is circumstantial evidence that males are chemically attracted to queens. After the mating flight, the queens found new colonies independently and singly. Excavation of these founding colonies reveals first insights into their structure.

    This article reports a study of the founding of applied behavior analysis through its publications. Our methods included hand searches of sources (e.g., journals, reference lists), search terms (i.e., early, applied, behavioral, research, literature), inclusion criteria (e.g., the field's applied dimension), and (d) challenges to their face and content validity. Our results were 36 articles published between 1959 and 1967 that we organized into 4 groups: 12 in 3 programs of research and 24 others. Our discussion addresses (a) limitations in our method (e.g., the completeness of our search), (b) challenges to the validity of our methods and results (e.g., convergent validity), and (c) priority claims about the field's founding. We conclude that the claims are irresolvable because identification of the founding publications depends significantly on methods and because the field's founding was an evolutionary process. We close with suggestions for future research. PMID:25729133

    Blakeney, P

    1995-01-01

    School reintegration programs have been developed to enhance a positive sense of self-worth in a child who has been burned. The premise of these programs is that cognitive and affective education about children with burns will diminish the anxiety of the patient with burns, the patient's family, faculty and staff of the school, and the students. Five principles guide school reentry programs: (1) preparation begins as soon as possible; (2) planning includes the patient and family; (3) each program is individualized; (4) each patient is encouraged to return to school quickly after hospital discharge; and (5) burn team professionals remain available for consultation to the school. Reintegration programs can vary in format depending on patient and/or family need and capability of the burn team, thus allowing flexibility in assisting every child with burns make the transition from hospital patient to normal living.

  2. Genomic identification of founding haplotypes reveals the history of the selfing species Capsella rubella.

    Directory of Open Access Journals (Sweden)

    Yaniv Brandvain

    Full Text Available The shift from outcrossing to self-fertilization is among the most common evolutionary transitions in flowering plants. Until recently, however, a genome-wide view of this transition has been obscured by both a dearth of appropriate data and the lack of appropriate population genomic methods to interpret such data. Here, we present a novel population genomic analysis detailing the origin of the selfing species, Capsella rubella, which recently split from its outcrossing sister, Capsella grandiflora. Due to the recency of the split, much of the variation within C. rubella is also found within C. grandiflora. We can therefore identify genomic regions where two C. rubella individuals have inherited the same or different segments of ancestral diversity (i.e. founding haplotypes present in C. rubella's founder(s. Based on this analysis, we show that C. rubella was founded by multiple individuals drawn from a diverse ancestral population closely related to extant C. grandiflora, that drift and selection have rapidly homogenized most of this ancestral variation since C. rubella's founding, and that little novel variation has accumulated within this time. Despite the extensive loss of ancestral variation, the approximately 25% of the genome for which two C. rubella individuals have inherited different founding haplotypes makes up roughly 90% of the genetic variation between them. To extend these findings, we develop a coalescent model that utilizes the inferred frequency of founding haplotypes and variation within founding haplotypes to estimate that C. rubella was founded by a potentially large number of individuals between 50 and 100 kya, and has subsequently experienced a twenty-fold reduction in its effective population size. As population genomic data from an increasing number of outcrossing/selfing pairs are generated, analyses like the one developed here will facilitate a fine-scaled view of the evolutionary and demographic impact of the

  3. Was bioethics founded on historical and conceptual mistakes about medical paternalism?

    Science.gov (United States)

    McCullough, Laurence B

    2011-02-01

    Bioethics has a founding story in which medical paternalism, the interference with the autonomy of patients for their own clinical benefit, was an accepted ethical norm in the history of Western medical ethics and was widespread in clinical practice until bioethics changed the ethical norms and practice of medicine. In this paper I show that the founding story of bioethics misreads major texts in the history of Western medical ethics. I also show that a major source for empirical claims about the widespread practice of medical paternalism has been misread. I then show that that bioethics based on its founding story deprofessionalizes medical ethics. The result leaves the sick exposed to the predatory power of medical practitioners and healthcare organizations with only their autonomy-based rights to non-interference, expressed in contracts, to protect them. The sick are stripped of the protection afforded by a professional, fiduciary relationship of physicians to their patients. Bioethics based on its founding story reverts to the older model of a contractual relationship between the sick and medical practitioners not worthy of intellectual or moral trust (because such trust cannot be generated by what I call 'deprofessionalizing bioethics'). On closer examination, bioethics based on its founding story, ironically, eliminates paternalism as a moral category in bioethics, thus causing bioethics to collapse on itself because it denies one of the necessary conditions for medical paternalism. Bioethics based on its founding story should be abandoned. © 2010 Blackwell Publishing Ltd.

  4. Co-founding ant queens prevent disease by performing prophylactic undertaking behaviour.

    Pull, Christopher D; Cremer, Sylvia

    2017-10-13

    Social insects form densely crowded societies in environments with high pathogen loads, but have evolved collective defences that mitigate the impact of disease. However, colony-founding queens lack this protection and suffer high rates of mortality. The impact of pathogens may be exacerbated in species where queens found colonies together, as healthy individuals may contract pathogens from infectious co-founders. Therefore, we tested whether ant queens avoid founding colonies with pathogen-exposed conspecifics and how they might limit disease transmission from infectious individuals. Using Lasius niger queens and a naturally infecting fungal pathogen Metarhizium brunneum, we observed that queens were equally likely to found colonies with another pathogen-exposed or sham-treated queen. However, when one queen died, the surviving individual performed biting, burial and removal of the corpse. These undertaking behaviours were performed prophylactically, i.e. targeted equally towards non-infected and infected corpses, as well as carried out before infected corpses became infectious. Biting and burial reduced the risk of the queens contracting and dying from disease from an infectious corpse of a dead co-foundress. We show that co-founding ant queens express undertaking behaviours that, in mature colonies, are performed exclusively by workers. Such infection avoidance behaviours act before the queens can contract the disease and will therefore improve the overall chance of colony founding success in ant queens.

  5. Memory for found targets interferes with subsequent performance in multiple-target visual search.

    Science.gov (United States)

    Cain, Matthew S; Mitroff, Stephen R

    2013-10-01

    Multiple-target visual searches--when more than 1 target can appear in a given search display--are commonplace in radiology, airport security screening, and the military. Whereas 1 target is often found accurately, additional targets are more likely to be missed in multiple-target searches. To better understand this decrement in 2nd-target detection, here we examined 2 potential forms of interference that can arise from finding a 1st target: interference from the perceptual salience of the 1st target (a now highly relevant distractor in a known location) and interference from a newly created memory representation for the 1st target. Here, we found that removing found targets from the display or making them salient and easily segregated color singletons improved subsequent search accuracy. However, replacing found targets with random distractor items did not improve subsequent search accuracy. Removing and highlighting found targets likely reduced both a target's visual salience and its memory load, whereas replacing a target removed its visual salience but not its representation in memory. Collectively, the current experiments suggest that the working memory load of a found target has a larger effect on subsequent search accuracy than does its perceptual salience.

    2014-01-01

    The human microbiome is influenced by a number of factors, including environmental exposure to microbes. Because many humans spend a large amount of time in built environments, it can be expected that the microbial ecology of these environments will influence the human microbiome. In an attempt to further understand the microbial ecology of built environments, the microbiota of car interiors was analyzed using culture dependent and culture independent methods. While it was found that the number and type of bacteria varied widely among the cars and sites tested, Staphylococcus and Propionibacterium were nearly always the dominant genera found at the locations sampled. Because Staphylococcus is of particular concern to human health, the characteristics of this genus found in car interiors were investigated. Staphylococcus epidermidis, S. aureus, and S. warnerii were the most prevalent staphylococcal species found, and 22.6% of S. aureus strains isolated from shared community vehicles were resistant to methicillin. The reduction in the prevalence of pathogenic bacteria in cars by using silver-based antimicrobial surface coatings was also evaluated. Coatings containing 5% silver ion additives were applied to steering wheels, placed in cars for five months and were found to eliminate the presence of culturable pathogenic bacteria recovered from these sites relative to controls. Together, these results provide new insight into the microbiota found in an important built environment, the automobile, and potential strategies for controlling the presence of human pathogens.

    1996-07-01

    Native Americans have been classified into four founding haplogroups with as many as seven founding lineages based on mtDNA RFLPs and DNA sequence data. mtDNA analysis was completed for 83 Yanomami from eight villages in the Surucucu and Catrimani Plateau regions of Roraima in northwestern Brazil. Samples were typed for 15 polymorphic mtDNA sites (14 RFLP sites and 1 deletion site), and a subset was sequenced for both hypervariable regions of the mitochondrial D-loop. Substantial mitochondrial diversity was detected among the Yanomami, five of seven accepted founding haplotypes and three others were observed. Of the 83 samples, 4 (4.8%) were lineage B1, 1 (1.2%) was lineage B2, 31 (37.4%) were lineage C1, 29 (34.9%) were lineage C2, 2 (2.4%) were lineage D1, 6 (7.2%) were lineage D2, 7 (8.4%) were a haplotype we designated "X6," and 3 (3.6%) were a haplotype we designated "X7." Sequence analysis found 43 haplotypes in 50 samples. B2, X6, and X7 are previously unrecognized mitochondrial founding lineage types of Native Americans. The widespread distribution of these haplotypes in the New World and Asia provides support for declaring these lineages to be New World founding types.

  11. The influence of school culture and school climate on violence in schools of the Eastern Cape Province

    2012-01-01

    Full Text Available This article reports on research undertaken about the influence of school culture and school climate on violence at schools in the Eastern Cape. An adapted California School Climate and Survey - Short Form (CSCSS-SF, which was used as the data-collection instrument, was completed by 900 Grade 10 to 12 learners. With the assistance of Pearson's product moment correlation coefficient, it was found that the better the school culture and school climate are at a school, the lower the levels of school violence. On the other hand, a lack of school safety contributed to learners experiencing higher levels of violence at schools. The results of hierarchy regression analyses indicated that school culture and school climate can be used to explain a significant percentage of variance in school violence. The f² values indicate that, with the exception of two aspects of the variance physical and verbal harassment, the results did not have any practical value. The article concludes with a few suggestions on how the results can be used to address school violence.

    Common variants of APOA5 gene affect plasma triglyceride (TG) in the population and a number of rare variants APOA5 have been reported in individuals with hypertriglyceridemia (HTG). APOA5 was analysed in 98 HTG individuals (plasma TG >9 mmol/L) in whom no mutations in LPL and APOC2 had been found. Two patients were found to be heterozygous for two novel APOA5 variants. The first variant (p.L253P) was identified in an obese male who consumed a diet rich in fat and simple sugars. He was also a carrier in trans of the common TG-raising p.S19W SNP (5*3 haplotype). The second variant (c.295-297 del GAG, p.E99 del) was found in a lean male with no life style or metabolic factors known to affect plasma TG. He was a carrier in trans of the TG-raising 5*2 haplotype and was homozygous for the rare c.1337T allele of a SNP of GCKR gene. No mutations in other genes affecting plasma TG (LMF1 and GPIHBP1) were found in these patients. These APOA5 variants, resulted to be deleterious in silico, were not found in 350 control subjects. These novel APOA5 variants predispose to HTG in combination with other genetic or nutritional factors. Copyright © 2011 Elsevier B.V. All rights reserved.

    Truancy continues to be a major problem, affecting most school districts in the U.S. Truancy is related to school dropout, with associated adverse consequences, including unemployment and delinquency. It is important to obtain a more complete picture of truants' educational experience. First, the present study sought to examine the longitudinal growth (increasing/decreasing trend) in truant youths' attitudes toward school and misbehavior in school (disobedience, inappropriate behavior, skipping school). Second, this study focused on examining the impact of a Brief Intervention (BI) targeting the youths’ substance use, as well as socio-demographic and background covariates, on their attitudes toward school and school behavior problems over time. A linear growth model was found to fit the attitudes toward school longitudinal data, suggesting the youths’ attitudes toward school are related across time. An auto-regressive lag model was estimated for each of the school misbehaviors, indicating that, once initiated, youth continued to engage in them. Several socio-demographic covariates effects were found on the youths’ attitudes towards school and school misbehaviors over time. However, no significant, overall BI effects were uncovered. Some statistically significant intervention effects were found at specific follow-up points for some school misbehaviors, but none were significant when applying the Holm procedure taking account of the number of follow-ups. The implications of these findings are discussed. PMID:25247027

    We examined the frequency of incidentally found or unexpected tumors discovered at the time of magnetic resonance imaging (MRI) examinations in the temporomandibular joint (TMJ) region for patients with suspicion of TMJ arthrosis. Five MR images (T1-weighted transverse scout image and proton density and T2-weighted oblique sagittal images at the open and closed mouth) were acquired. In 2776 MRI examinations of TMJ arthrosis, two tumors were discovered. They consisted of an adenoid cystic carcinoma in the deep portion of the parotid gland, and a malignant tumor extending from the infratemporal fossa to the parapharyngeal space. The rate of incidentally founded or unexpected tumors in TMJ examinations was low (0.072%), but the two tumors found were malignant tumors, and therefore, scout image should be carefully examined, not only used for positing the slice.

These data agreed with those of the glasses of the Pre-Han period found in China, suggesting the presence of possible trade between China in the Pre-Han Period (ca. fourth-third centuries B.C.) and Japan in the earlier Yayoi period (ca. first century B.C.).

    We investigated the hypothesis that a sociocultural variable known as the culture of honor would be uniquely predictive of school-violence indicators. Controlling for demographic characteristics associated in previous studies with violent crime among adults, we found that high-school students in culture-of-honor states were significantly more likely than high-school students in non-culture-of-honor states to report having brought a weapon to school in the past month. Using data aggregated over a 20-year period, we also found that culture-of-honor states had more than twice as many school shootings per capita as non-culture-of-honor states. The data revealed important differences between school violence and general patterns of homicide and are consistent with the view that many acts of school violence reflect retaliatory aggression springing from intensely experienced social-identity threats.

    The National Institut of Nuclear Sciences and Techniques founded of 2001 a National School of Dismantling, NSD, at the end, which was validated by CEA, COGEMA, EDF and ANDRA. This school addresses four major issues: Decontamination; Dismantling; Demolition and waste Disposal (4D). Dedicated for instructing scientific and technical knowledge and know-how, needed in dismantling the nuclear installations, NSD has as targets: - personnel at engineering and operational level; - personnel occupied with involved trades from conception through intervention; - students and employees on leave; - employees while training on the job. Initial basic education for students in collaboration with schools and universities concerns: - master degree in radioactive waste management; - master degree in dismantling; - professional license in 3 D; - pro 4 D graduation. NSD is also engaged in continual formation for employees qualified, or not, adapted to the needs generated by the following tasks and personnel: - introduction in dismantling; - project team; - specialist engineer; - team head; - agent for remedial action; - agent for dismantling. The National School of Dismantling joins a network of human and technological capabilities confined within the 4 D frame, namely: - scientific and technical competencies (experts, instructors working in the nuclear field and dismantling); - pedagogical competence (professionals from basic and continual education); - specific material means such as those used by construction site schools, mock-ups, rooms for practical training etc

    DJ-1 is a multi-functional protein that plays roles in transcriptional regulation and anti-oxidative stress, and loss of its function is thought to result in onset of Parkinson's disease. We have previously reported that L166P, a mutant DJ-1 found in Parkinson's disease patients, had no activity to prevent hydrogen peroxide (H 2 O 2 )-induced cell death. In this study, we analyzed other mutants of DJ-1 found in Parkinson's disease patients, including M26I, R98Q, and D149A, as well as L166P. We first found that all of the mutants made heterodimers with wild-type DJ-1, while all of the mutants except for L166P made homodimers. We then found that M26I and L166P, both of which are derived from homozygous mutations of the DJ-1 gene, were unstable and that their stabilities were recovered, in part, in the presence of proteasome inhibitor, MG132. NIH3T3 cell lines stably expressing these mutants of DJ-1 showed that cell lines of L166P and C106S, a mutant for protease activity (-) of DJ-1, had no activity to scavenge even endogenously producing reactive oxygen species. These cell lines also showed that all of the mutants had reduced activities to eliminate exogenously added H 2 O 2 and that these activities, except for that of D149A, were parallel to those preventing H 2 O 2 -induced cell death

  20. Bacterial communities found in placental tissues are associated with severe chorioamnionitis and adverse birth outcomes.

    Directory of Open Access Journals (Sweden)

    Ronan M Doyle

    Full Text Available Preterm birth is a major cause of neonatal mortality and morbidity worldwide. Bacterial infection and the subsequent inflammatory response are recognised as an important cause of preterm birth. It is hypothesised that these organisms ascend the cervical canal, colonise placental tissues, cause chorioamnionitis and in severe cases infect amniotic fluid and the foetus. However, the presence of bacteria within the intrauterine cavity does not always precede chorioamnionitis or preterm birth. Whereas previous studies observing the types of bacteria present have been limited in size and the specificity of a few predetermined organisms, in this study we characterised bacteria found in placental tissues from a cohort of 1391 women in rural Malawi using 16S ribosomal RNA gene sequencing. We found that specific bacteria found concurrently on placental tissues associate with chorioamnionitis and delivery of a smaller newborn. Severe chorioamnionitis was associated with a distinct difference in community members, a higher bacterial load and lower species richness. Furthermore, Sneathia sanguinengens and Peptostreptococcus anaerobius found in both matched participant vaginal and placental samples were associated with a lower newborn length-for-age Z-score. This is the largest study to date to examine the placental microbiome and its impact of birth outcomes. Our results provide data on the role of the vaginal microbiome as a source of placental infection as well as the possibility of therapeutic interventions against targeted organisms during pregnancy.

    Ancient DNA from the bone remains of 25 out of 28 pre-Columbian individuals from the Late Classic-Postclassic Maya site of Xcaret, Quintana Roo, was recovered, and mitochondrial DNA (mtDNA) was amplified by using the polymerase chain reaction. The presence of the four founding Amerindian mtDNA lineages was investigated by restriction analysis and by direct sequencing in selected individuals. The mtDNA lineages A, B, and C were found in this population. Eighty-four percent of the individuals were lineage A, whereas lineages B and C were present at low frequencies, 4% and 8%, respectively. Lineage D was absent from our sample. One individual did not possess any of the four lineages. Six skeletons out of 7 dated from the Late Classic period were haplotype A, whereas 11 skeletons out of 16 dated from the Postclassic period were also haplotype A. The distribution of mtDNA lineages in the Xcaret population contrasts sharply with that found in ancient Maya from Copán, which lack lineages A and B. On the other hand, our results resemble more closely the frequencies of mtDNA lineages found in contemporary Maya from the Yucatán Peninsula and in other Native American contemporary populations of Mesoamerican origin.

    The radon testing survey in Metropolitan Toronto public schools was the most intensive project of its kind ever undertaken in Canadian schools. It also included an extensive public education program on radiation and radon-in-schools. The radon levels at 632 schools were measured using the CAIRS Radon Monitors. Ninety percent of the locations measured were found to have a radon level equal to or less than 2 mWL. Two locations in two different schools were found to have a radon level at or above the Action Level (20 mWL). The remaining results were between the two extremes. Follow-up testing in those schools where more than 10 mWL of radon was found is in progress. (author)

Some recent research is beginning to consider the effects of groups of strengths, combined as a higher order variable and termed covitality. This study investigated the combined influence of four positive character traits, gratitude, optimism, zest and persistence, upon school engagement, within a sample of 112 Australian primary school students. The combined effect of these four traits, in defining covitality as a higher or second-order factor within a path analysis, was found to predict relatively higher levels of school engagement and pro-social behaviour.

    Full Text Available Thymoma, the most common neoplasm of the anterior mediastinum, is a rare tumor of thymic epithelium that can be locally invasive. We reported 2 cases of invasive thymoma incidentally found during routine coronary artery bypass graft (CABG surgery at Faghihee Hospital of Shiraz University of Medical Sciences of Iran in a period of about 6 months. The 2 patients were male and above 60 years old. They had no clinical symptoms and radiological evidence of mediastinal mass before detection of the tumor during operation. For both patients mass was completely excised and sent to the laboratory. The ultimate pathological diagnosis of both masses was invasive thymoma (stage 2. There are few reports in which thymomas were found incidentally during cardiac surgery. In spite of rare coincidence, due to being asymptomatic and possibly invasive, special attention to thymus gland during cardiac surgery or other mediastinal surgery and preoperative imaging studies seem to be reasonable approach.

When the tale is analysed in comparison to other variants it is found that in the Chinese version Yeh-Shen (Cinderella is prized for the small size of her feet. The result of Yeh-Shen having small feet in the story is that she is led her into wealth, power and marriage, the same pursuable goals that led to the custom of footbinding. In southern China the custom of footbinding became a historically defining feature of the society. A women's beauty and her delicacy were judged by the size of her feet, and small feet were the aim of the binding. Small feet played such an important role in the society that it can be found as early as the ninth century C.E., in the traditional oral story, Yeh-Shen.

    Food supplements are regularly found to contain pharmacologically active substances. Recently, the food supplement Dexaprine was removed from the Dutch market because it was associated with severe adverse events. Reports to the Dutch Poisons Information Center (DPIC) showed that ingestion of as little as half a tablet caused several cases of nausea, agitation, tachycardia, and palpitations and even one case of cardiac arrest. The remaining tablets of four patients were sent in by different healthcare professionals. Analysis by ultra-performance liquid chromatography quadrupole time of flight mass-spectrometry (UPLC-QTOF-MS) confirmed the presence of synephrine, oxilofrine, deterenol, yohimbine, caffeine, and theophylline. Two more compounds were found which were tentatively identified as β-methyl-β-phenylethylamines. This incident is only the next in a series of similar incidents involving dietary supplements with (undeclared) active substances that are either unsafe or have no known safety profile.

The results showed differences in the various Campylobacter populations, e.g. the Danish population as reflected in the domestically acquired infections and the Danish-produced food was more uniform than the isolates......The subtypes of Campylobacter isolates from human infections in two Danish counties were compared to isolates from retail food samples and faecal samples from chickens, pigs and cattle. During a 1-year period, 1285 Campylobacter isolates from these sources were typed by two methods: 'Penner' heat......-stable serotyping and automated ribotyping (RiboPrinting). C. jejuni was the dominating species, but C. coli was more prevalent among food and chicken isolates (16%) compared to human isolates (4%). In total, 356 different combined sero-ribotypes (subtypes) were found. A large subtype overlap was seen between human...

  11. The art of compromise: the founding of the National Gallery of British Art, 1890-1892

    Directory of Open Access Journals (Sweden)

    Amy Woodson-Boulton

    2015-03-01

    Full Text Available This article argues that the press played a key role in defining the Tate Gallery by facilitating a national debate about the siting, nature, and purpose of the proposed National Gallery of British Art. Art critics, politicians, journalists and a variety of newspaper editors weighed in on whether Britain should create a museum of modern art, a museum of national art, or both. The understanding of British art as quintessentially modern at the time of the founding of the Gallery meant that from the beginning the Tate Gallery was founded as both the National Gallery of British Art and a museum of modern art. The changing definition of modern art in the twentieth century, however, created fractures between these two identities that eventually led to the split between Tate Britain and Tate Modern.

    A large quantity of uranous salt samples was found in an unused laboratory in Niamey (Capital City). The National Center of Radiation Protection (Centre National de Radioprotection (CNRP)), in collaboration with the Ministry of Mines and Energy (MM/E), has carried out the recuperation of several hundred kilograms of uranous salt and the decontamination of the area. At the end of the operation, 1813 uranous salt samples with average mass of 250 grams and two old calibration sources were found. Such quantities of uranous salt powder, hold near the river without control is a real hazard for the public because of probable act of vandalism. The regulatory body might continue in informing and sensitizing workers and public for recovering other orphaned sources and prevent sanitary hazards as the one solved at the ONAREM Laboratory.

    Very little is known about how the spa gene mutates over time in methicillin-resistant Staphylococcus aureus (MRSA) from the same patient. Copenhagen is an area with low prevalence of MRSA but with high variability in spa types. We collected 1536 MRSA isolates from 319 patients during a 5-year...... period and found spa type alterations in 30 MRSA isolates (2%) from 13 patients (4%). The alteration most often seen was the deletion of repeats followed by repeat duplication and point mutation....

    Under the auspices of Bacchus! Acutissimins, natural flavano-ellagitannins, occur in oak-aged wine as a result of a diastereoselective condensation reaction of the flavan-3-ol catechin, a component of grapes, with the C-glucosidic ellagitannin vescalagin, found in oak. The acutissimins are further converted into natural mongolicains and analogues of camelliatannin G in a remarkably chemoselective fashion by simple aerobic oxidation.

    Conclusion: Although the positive CEA, CYFRA 21-1, NSE, and TSGF rates were observed at low values during the NSLCLC serum diagnosis, they still played an important role in diagnosing lung cancer. Significant levels of CEA, CYFRA 21-1, NSE, and TSGF were detected in the serum. The amounts found were useful for diagnosing NSCLC patients who depended on the currently limited biomarker development.

    The significant excess recently found by the CDF Collaboration in the inclusive jet cross section for jet transverse energies E T ≥ 200 GeV over current QCD predictions can be explained either by possible production of excited bosons (excited gluons, weak bosons, Higgs scalars, etc.) or by that of excited quarks. The masses of the excited boson and the excited quark are estimated to be around 1600 GeV and 500 GeV, respectively. (author)

    1982-01-01

    A DNA found in post-mitochondrial fractions from Ehrlich ascites cells, comprising 0.2% of the total cellular DNA, is partially characterized. It appears in cytoplasmic homogenates as a 14.6 S molecule, and is eluted from hydroxyapatite with 0.24 M sodium phosphate buffer. Its Cs 2 SO 4 buoyant density is lower than Erlich ascites tumor nuclear DNA and it has low dG+dC content, as determined by chromatography of hydrolysates of 32 P-labelled DNA. It is enriched in sequences which reassociate rapidly in the presence of excess nuclear DNA. It can be used as promoter for DNA synthesis by an endogenous DNA-dependent DNA polymerase found in association with the post-mitochondrial preparations. It is found to be associated with newly incorporated radioactivity following incubation in vitro with labelled UTP. Its localization in situ has not yet been attempled. It is thought to represent viral A-type particle associated, or plasma membrane associated DNA. (author) [pt

  4. A divergent Cardinium found in daddy long-legs (Arachnida: Opiliones).

    2010-11-01

    Recent studies indicate that a newly described bacterial endosymbiont, Cardinium, is widespread in arthropods and induces different reproductive manipulations in hosts. In this study, we used a portion of the 16S rRNA gene of the Cardinium to screen 16 Opilionid species from the suborder Palptores. We found the incidence of Cardinium in these Opiliones was significantly higher than in other pooled arthropods (31.2% versus 7.2%, P=0.007). Phylogenetic analyses using maximum parsimony (MP) and Bayesian analysis revealed two distinct clades in Opiliones. One is a divergent monophyletic clade with strong support that has so far not been found in other arthropods, and a second one contains Cardinium both from Opiliones and other arthropods. There is not complete concordance of the Cardinium strains with host phylogeny, suggesting some horizontal movement of the bacteria among Opiliones. Although the divergence in the sequenced 16S rRNA region between the Cardinium infecting Opiliones and Cardinium from other arthropods is greater than among Cardinium found in other arthropods, all are monophyletic with respect to the outgroup bacteria (endosymbionts of Acanthamoeba). Based on high pairwise genetic distances, deep branch, and a distinct phylogenetic grouping, we conclude that some Opiliones harbor a newly discovered Cardinium clade. Copyright © 2010 Elsevier Inc.

    A small number of free-living viruses have been found to be obligately vertically transmitted, but it remains uncertain how widespread vertically transmitted viruses are and how quickly they can spread through host populations. Recent metagenomic studies have found several insects to be infected with sigma viruses (Rhabdoviridae). Here, we report that sigma viruses that infect Mediterranean fruit flies (Ceratitis capitata), Drosophila immigrans, and speckled wood butterflies (Pararge aegeria) are all vertically transmitted. We find patterns of vertical transmission that are consistent with those seen in Drosophila sigma viruses, with high rates of maternal transmission, and lower rates of paternal transmission. This mode of transmission allows them to spread rapidly in populations, and using viral sequence data we found the viruses in D. immigrans and C. capitata had both recently swept through host populations. The viruses were common in nature, with mean prevalences of 12% in C. capitata, 38% in D. immigrans and 74% in P. aegeria We conclude that vertically transmitted rhabdoviruses may be widespread in a broad range of insect taxa, and that these viruses can have dynamic interactions with their hosts. © 2017 The Authors.

  7. Chronology, Narrative, and Founding Acts: Between a Transcendental Rock and a Decisionist Hard Place

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available In attempting to represent political transformations, we often encounter a moment that seems to resist narrativisation, a moment of obstinate inconsistency which various theoretical, historical and fictional accounts cannot properly absorb except by way of indicating the parameters of a rupture. Here, I present a position which views these unrepresentable moments as structurally necessary features of revolutionary events. It is not simply that, at such historical junctures, we are faced with an abundance of information and that the unrepresentability or narrative deficit is the consequence of this surplus; on the contrary, the founding act that accompanies any radical transformation necessarily involves a certain temporal contraction. To the extent that narrative relies on a linear chronology, it fails to capture this moment of contraction. Indeed, this is why works of political philosophy associated with a founding contract (for example Hobbes’s Leviathan and Rousseau’s Social Contract cannot fully suppress the moment of circularity in which the rhythm of chronological time skips a beat and, to paraphrase Rousseau, one requires an effect to perform the function associated with its own cause. If the moment of founding can be represented at all, it is only by way of paradox and metaphor.

  8. Spiders (Araneae) Found in Bananas and Other International Cargo Submitted to North American Arachnologists for Identification.

    Spiders found in international cargo brought into North America are sometimes submitted to arachnologists for identification. Often, these spiders are presumed to be of medical importance because of size or a submitter's familiarity with a toxic spider genus from the continent of origin. Starting in 2006, requests were made for spiders found in international cargo brought into North America, in addition to the specimens from similar cargo shipments already in our museum collections. This was an ad hoc study that allowed us to focus on spiders of concern to the discoverer. We identified 135 spiders found in international cargo. A key for the most common species is provided. The most frequently submitted spiders were the pantropical huntsman spider, Heteropoda venatoria (L.) (Sparassidae), and the redfaced banana spider, Cupiennius chiapanensis Medina Soriano (Ctenidae). Spiders of medical importance were rare. The most common cargo from which spiders were submitted was bananas with most specimens coming from Central America, Ecuador, or Colombia. Lack of experience with nonnative fauna caused several experienced American arachnologists to misidentify harmless ctenid spiders (C. chiapanensis, spotlegged banana spider, Cupiennius getazi Simon) as highly toxic Phoneutria spiders. These misidentifications could have led to costly, unwarranted prophylactic eradication measures, unnecessary employee health education, heightened employee anxiety and spoilage when perishable goods are left unloaded due to safety concerns. © 2014 Entomological Society of America.

  9. Can schools reduce bullying? The relationship between school characteristics and the prevalence of bullying behaviours.

    2017-06-01

    Bullying remains a persistent phenomenon in schools, but the extent to which day-to-day policies and practices relate to bullying prevalence has not been widely studied. In this study, we use an educational effectiveness framework to interrogate this relationship. The aim was to study the relationship between school factors and prevalence of bullying in primary schools. We hypothesize that school conditions (e.g., size), school policies (e.g., behaviour policies), and school processes (e.g., teaching quality) are related to bullying prevalence. Surveys were administered to pupils in 35 primary schools in four local authorities in England. Pupils (N = 1,411) and teachers (N = 68) in the final year of primary school (year 6) were surveyed. This study drew on the following data sources: A pupil survey on bullying behaviours A survey of teachers on school policies and processes Analysis of data on school processes from school inspection reports Analysis of secondary data on school conditions and pupil characteristics. Three-level multilevel models were used to analyse the data. Results show a substantial school- and classroom-level effect on prevalence of bullying. Effective school policies were found to be related to levels of bullying. The study provides support for the importance of schools' embedded policies and practices in relation to bullying prevalence and provides evidence for policy on the importance of focusing on a broad range of outcomes. © 2017 The British Psychological Society.

  10. Striking Graphite Bearing Clasts Found in Two Ordinary Chondrite Samples; NWA6169 and NWA8330

    Meteorites play an integral role in understanding the history of the solar system. Not only can they contain some of the oldest material found in the solar system they also can contain material that is unique. Many lithologies are only found as foreign clasts within distinctly different host meteorites. In this investigation two foreign clasts within the meteorites, NWA6169 and NWA8330 were studied. The purpose of this investigation was to examine the mineralogy and petrography of the clasts within the samples. From there an identification and possible origin were to be inferred. NWA6169 is an unclassified ordinary chondrite that has a presumed petrologic type of L3. NWA8330 is a classified ordinary chondrite that has a petrologic type of LL3. Both meteorites were found to contain clasts that were similar; both modally were comprised of about 5% acicular graphite. Through SEM and Raman Spectroscopy it was found that they contained olivine, pyroxene, plagioclase, Fe-Ni sulfides, graphite, and metals. They were found to portray an igneous texture with relationships that suggest concurrent growth. Analytical microprobe results for NWA6169 revealed mineral compositions of Fa31-34, Fs23-83, and Ab7-85. For NWA8330 these were Fa28-32, Fs10-24, and Ab4-83. Only one similar material has been reported, in the L3 chondrite Krymka (Semenenko & Girich, 1995). The clast they described exhibited similar mineralogies including the unusual graphite. Krymka data displayed compositional values of Fa28.5-35.0 and Fs9-25.9. These ranges are fairly similar to that of NWA6169 and NWA8330. These samples may all be melt clasts, probably of impact origin. Two possibilities are (1) impact of a C-type asteroid onto the L chondrite parent asteroid, and (2) a piece of proto-earth ejected from the moon-forming collision event. These possibilities present abundant questions, and can be tested. The measurement of oxygen isotope compositions from the clasts should reveal the original source of the

    The NIH and Department of Health & Human Services recommend online patient information (OPI) be written at a sixth grade level. We used a panel of readability analyses to assess OPI from NCI-Designated Cancer Center (NCIDCC) Web sites. Cancer.gov was used to identify 68 NCIDCC Web sites from which we collected both general OPI and OPI specific to breast, prostate, lung, and colon cancers. This text was analyzed by 10 commonly used readability tests: the New Dale-Chall Readability Formula, Flesch Reading Ease scale, Flesch-Kinaid Grade Level, FORCAST scale, Fry Readability Graph, Simple Measure of Gobbledygook test, Gunning Frequency of Gobbledygook index, New Fog Count, Raygor Readability Estimate Graph, and Coleman-Liau Index. We tested the hypothesis that the readability of NCIDCC OPI was written at the sixth grade level. Secondary analyses were performed to compare readability of OPI between comprehensive and noncomprehensive centers, by region, and to OPI produced by the American Cancer Society (ACS). A mean of 30,507 words from 40 comprehensive and 18 noncomprehensive NCIDCCs was analyzed (7 nonclinical and 3 without appropriate OPI were excluded). Using a composite grade level score, the mean readability score of 12.46 (ie, college level: 95% CI, 12.13-12.79) was significantly greater than the target grade level of 6 (middle-school: Preadability metrics (P<.05). ACS OPI provides easier language, at the seventh to ninth grade level, across all tests (P<.01). OPI from NCIDCC Web sites is more complex than recommended for the average patient.

    Use of supplements is common among men seeking urologic evaluation for sexual health matters. With a dizzying array of formulations available and little regulation on the dosage, purity, or ingredients found in these products, the health effects of nutraceuticals are often confusing to patients and medical practitioners alike. In this review, we set out to concisely summarize the data on ingredients found within the top-selling nutraceutical agents marketed for men's sexual health in order to provide a clinical guide for urologists. We used sales data from the most popular retail provider of men's health supplements to identify the top-selling products marketed toward improvement of men's sexual health. We summarized the available information related to the ingredients, dosage, cost, and mechanism of action for these substances and performed an extensive literature search to identify and review the current evidence available for each of the most common ingredients found in these nutraceuticals. The top-selling nutraceuticals marked for men's sexual health contain a blend of multiple supplements (up to 33 in one formulation identified), the most common being ginseng, tribulus, zinc, horny goat weed, B complex vitamins/trace minerals, fenugreek, L-arginine, maca, DHEA, ginkgo, and yohimbine. The currently available medical literature evaluating the efficacy of these substances is generally of low quality. Despite the dearth of evidence supporting nutraceutical agents in the men's health arena, these substances are still commonly used by patients. As these products can affect the health and well-being of men presenting to a urology clinic, a familiarity with commonly used agents can help the urologist appropriately counsel their patients. © 2015 International Society for Sexual Medicine.

    Although corn (Zea mays L.) and soybeans (Glycine max L.) do not require pollination, they offer floral resources used by insect pollinators. We asked if a similar community of insect pollinators visits these crops in central Iowa, a landscape dominated by corn and soybean production. We used modified pan traps (i.e., bee bowls) in both corn and soybean fields during anthesis and used nonmetric multidimensional scaling (NMS) to compare the communities found in the two crops. Summed across both crops, 6,704 individual insects were captured representing at least 60 species, morphospecies, or higher-level taxa. Thirty-four species were collected in both crops, 19 collected only in corn and seven were collected only in soybean. The most abundant taxa were Lasioglossum [Dialictus] spp., Agapostemon virescens Cresson, Melissodes bimaculata (Lepeletier), and Toxomerus marginatus (Say), which accounted for 65% of the insect pollinators collected from both crops. Although social bees (Apis mellifera L. and Bombus spp.) were found in both crops, they accounted for only 0.5% of all insects captured. The NMS analysis revealed a shared community of pollinators composed of mostly solitary, ground nesting bees. Many of these species have been found in other crop fields throughout North America. Although corn and soybean are grown in landscapes that are often highly disturbed, these data suggest that a community of pollinators can persist within them. We suggest approaches to conserving this community based on partnering with activities that aim to lessen the environmental impact of annual crop production. © The Authors 2016.

    Ginseng is not widely accepted by U.S. consumers due to its unfamiliar flavors, despite its numerous health benefits. Previous studies have suggested that the bitter compounds in chocolate and coffee may mask the off-flavors of ginseng. The objectives of this study were to: (1) profile sensory characteristics of ginseng extract solution, caffeine solution, cyclo (L-Pro-L-Val) solution, theobromine solution, and 2 model solutions simulating chocolate bitterness; and (2) determine the changes in the sensory characteristics of ginseng extract solution by the addition of the bitter compounds found in chocolate and coffee. Thirteen solutions were prepared in concentrations similar to the levels of the bitter compounds found in coffee and chocolate products. Twelve panelists participated in a descriptive analysis panel which included time-intensity ratings. Ginseng extract was characterized as sweeter, starchier, and more green tea than the other sample solutions. Those characteristics of ginseng extract were effectively modified by the addition of caffeine, cyclo (L-Pro-L-Val), and 2 model solutions. A model solution simulating dark chocolate bitterness was the least influenced in intensities of bitterness by the addition of ginseng extract. Results from time-intensity ratings show that the addition of ginseng extract increased duration time in certain bitterness of the 2 model solutions. Bitter compounds found in dark chocolate could be proposed to effectively mask the unique flavors of ginseng. Future studies blending aroma compounds of chocolate and coffee into such model solutions may be conducted to investigate the influence on the perception of the unique flavors through the congruent flavors. © 2012 Institute of Food Technologists®

    Correct identification of pigments and all accompanying phases found in colour layers of historical paintings are relevant for searching their origin and pigment preparation pathways and for specification of their further degradation processes. We successfully applied the analytical route combining non-destructive in situ X-ray fluorescence analyses with subsequent laboratory investigation of micro-samples by optical microscopy, scanning electron microscopy/energy-dispersive spectroscopy and X-ray powder micro-diffraction (micro-XRD) to obtain efficiently all the data relevant for mineralogical interpretations of the copper pigments origin. Cu salts (carbonates, chlorides, sulphates, etc.) used as pigments exist in a range of polymorphs with similar or identical composition. The efficiency of the micro-XRD for direct identification of such crystal phases present in micro-samples of colour layers was demonstrated in the presented paper. A new, until now unpublished, type of copper pigment--cumengeite, Pb(21)Cu(20)Cl(42)(OH)(40)--used as a blue pigment on a sacral wall painting in the Czech Republic was found by means of micro-XRD. Furthermore, azurite, malachite, paratacamite, atacamite and posnjakite were identified in fragments of colour layers of selected Gothic wall paintings. We found Cu-Zn arsenates indicating the natural origin of azurite and malachite; artificial malachite was distinguishable according to its typical spherulitic crystals. The corrosion of blue azurite to green basic Cu chloride was clearly evidenced on some places exposed to the action of salts and moisture-in a good agreement with the results of laboratory experiments, which also show that oxalic acid accelerates the corrosion of Cu pigments.

    Calibration is one of the long-standing problems in optical interferometric measurements, particularly with long baselines which demand stars with angular sizes on the milliarcsecond scale and no detectable companions. While systems of calibrators have been generally established for the near-infrared in the bright source regime (K {approx}< 3 mag), modern large interferometers are sensitive to significantly fainter magnitudes. We aim to provide a list of sources found to be unresolved from direct observations with high angular resolution and dynamic range, which can be used to choose interferometric calibrators. To this purpose, we have used a large number of lunar occultations recorded with the ISAAC instrument at the Very Large Telescope to select sources found to be unresolved and without close companions. An algorithm has been used to determine the limiting angular resolution achieved for each source, taking into account a noise model built from occulted and unocculted portions of the light curves. We have obtained upper limits on the angular sizes of 556 sources, with magnitudes ranging from K{sub s} Almost-Equal-To 4 to 10, with a median of 7.2 mag. The upper limits on possible undetected companions (within Almost-Equal-To 0.''5) range from K{sub s} Almost-Equal-To 8 to 13, with a median of 11.5 mag. One-third of the sources have angular sizes {<=}1 mas, and two-thirds have sizes {<=}2 mas. This list of unresolved sources matches well the capabilities of current large interferometric facilities. We also provide available cross-identifications, magnitudes, spectral types, and other auxiliary information. A fraction of the sources are found to be potentially variable. The list covers parts of the Galactic Bulge and in particular the vicinity of the Galactic Center, where extinction is very significant and traditional lists of calibrators are often insufficient.

    The Protein Data Bank (PDB) is one of the richest sources of structural biological information in the World. It started to exist as the computer-readable depository of crystallographic data complementing printed papers. The proper interpretation of the content of the individual files in the PDB still needs the detailed information found in the citing publication. An advanced graph theoretical method is presented here for automatically repairing, re-organising and re-structuring PDB data yielding the identification of all the protein-ligand complexes and all the binding sites in the PDB. As an application, we identified strong cysteine and tryptophan irregularities in the data.

    In the ant Pachycondyla villosa, new colonies are usually started cooperatively by two or more young queens who establish a dominance order with a division of labour. Co-founding can lead to primary polygyny, where queens stay together after workers have emerged. Here we show that two queens...... these were attacked and sometimes killed in queen associations. The removal of dominant alpha queens from three-queen associations resulted in beta queens obtaining the dominant role and sometimes the destruction of the existing eggs. It appears that two queens suffice for a successful association...

    2013-12-01

    Full Text Available ake found footage horror films have been massively made in the last two decades. To shoot a fictional script and give to it the texture of a documentary, a filmmaker has to deal with a number of creative restrictions in order to impose to images and sounds an effect of reality present in amateur footage. This essay examines recurring patterns of style, in this subgenre of movies, which have been used to combine narrative clarity and documental verisimilitude – a combination imposed by the presence of recording devices on the diegesis.

  16. Low Latitude Pelagic Foraminifera Found in the Hudson River: Are They Hurricane Deposits?

    River sediment cores provide a record of past environmental changes through stacked layers of sediments. In core CD02-29A, recovered from the southern Hudson River, a significant number of tropical planktic foraminifer tests were found. Foraminifera were concentrated in sediment layers of low impedance, suggesting high carbonate content. Because modern planktic foraminifera are exclusively marine, their presence in Hudson sediments in the core was remarkable. We can think of only two mechanisms that could explain this observation: either living specimens are carried upriver with the daily tides, or storm surges carry large amounts of seawater and re-suspended marine sediment upriver. To test for the presence of living specimens in Hudson River water, plankton tow samples were collected during high tide at the Hudson Battery south of the sample site, and at Piermont Pier north of the sample site and no living foraminifera were found. In addition, oxygen isotope (δ18O) analyses reveal a marine composition but the large difference in δ18O between the two surface dwelling species Globigerinoides ruber (pink) and Globigerinoides sacculifer, picked from the same sediment layer, suggests re-suspension and mixing of marine sediment deposits. Because only planktic, tropical to subtropical foraminiferal assemblages were found, the Hudson River deposits differ from previously recorded storm deposits found on Long Island and in New Jersey. In particular, the foraminiferal assemblages contain up to 40% G. ruber (pink), suggesting a highly tropical signal from a location where abundances of G. ruber are very low. This data, in addition to the pulsed occurrence of tests in the sediment suggests that the introduction of planktic foraminifera into the Hudson River must be driven by rare events. We suggest that storm surges from rare high-intensity hurricanes most likely explain the presence of these tests in Hudson River sediments, possibly assisted by the Gulf Stream entraining

    In response to persistent racial disparities in academic and behavioral outcomes between Black and White students, equitable school climate has drawn attention as a potential target for school reform. This study examined differences in Black and White students' experiences of school climate and explored whether indicators of school organizational health and staff burnout moderated differences in students' school experiences by race. Utilizing hierarchical linear modeling with a sample of 18,397 Black students (n=6228) and White students (n=12,169) and 2391 school staff in 53 schools, we found a consistent pattern of racial inequalities, such that Black students reported less positive experiences than White students across three indicators of school climate (caring γ=-0.08, porganizational health and student-reported school climate (e.g., staff affiliation and student-perceived equity, γ=0.07, porganizational health indicators were more strongly associated with positive perceptions of school climate among White students than Black students, translating into greater racial disparities in perceived school climate at schools with greater organizational health (e.g., supportive leadership by race on student-perceived engagement, γ=-0.03, p=.042). We also found negative associations between staff-reported burnout and students' experience of equity, such that the racial gap was smaller in schools with high ratings of burnout (γ=0.04, p=.002). These findings have implications for educators and education researchers interested in promoting school social contexts that equitably support student engagement and success.

    Glioblastoma multiforme (GBM) is the most frequent malignant brain tumor in adults, and its prognosis remains dismal despite intensive research and therapeutic advances. Diagnostic biomarkers would be clinically meaningful to allow for early detection of the tumor and for those cases in which surgery is contraindicated or biopsy results are inconclusive. Recent findings show that GBM cells release microvesicles that contain a select subset of cellular proteins and RNA. The aim of this hypothesis-generating study was to assess the diagnostic potential of miRNAs found in microvesicles isolated from the serum of GBM patients. To control disease heterogeneity, we used patients with newly diagnosed GBM. In the discovery stage, PCR-based TaqMan Low Density Arrays followed by individual quantitative reverse transcriptase polymerase chain reaction were used to test the differences in the miRNA expression levels of serum microvesicles among 25 GBM patients and healthy controls paired by age and sex. The detected noncoding RNAs were then validated in another 50 GBM patients. We found that the expression levels of 1 small noncoding RNA (RNU6-1) and 2 microRNAs (miR-320 and miR-574-3p) were significantly associated with a GBM diagnosis. In addition, RNU6-1 was consistently an independent predictor of a GBM diagnosis. Altogether our results uncovered a small noncoding RNA signature in microvesicles isolated from GBM patient serum that could be used as a fast and reliable differential diagnostic biomarker.

    The blood parasites from the genus Hepatozoon Miller, 1908 (Apicomplexa: Adeleida: Hepatozoidae) represent the most common intracellular protozoan parasites found in snakes. In the present study, we examined 209 individuals of snakes, from different zoogeographical regions (Africa, America, Asia and Europe), for the occurrence of blood parasites using both molecular and microscopic examination methods, and assess phylogenetic relationships of all Hepatozoon parasites from snakes for the first time. In total, 178 blood smears obtained from 209 individuals, representing 40 species, were examined, from which Hepatozoon unicellular parasites were found in 26 samples (14·6% prevalence). Out of 180 samples tested by molecular method polymerase chain reaction (PCR), the presence of parasites was observed in 21 individuals (prevalence 11·6%): 14 snakes from Africa belonging to six genera (Dendroaspis, Dispholidus, Mehelya, Naja, Philothamnus and Python), five snakes from Asia from the genus Morelia and two snakes from America, from two genera (Coluber and Corallus). The intensity of infection varied from one to 1433 infected cells per 10 000 erythrocytes. Results of phylogenetic analyses (Bayesian and Maximum Likelihood) revealed the existence of five haplotypes divided into four main lineages. The present data also indicate neither geographical pattern of studied Hepatozoon sp., nor congruency in the host association.

    MODY 5 and 6 have been shown to be low-penetrant MODYs. As the genetic background of unknown MODY is assumed to be similar, a new analytical strategy is applied here to elucidate genetic predispositions to unknown MODY. We examined to find whether there are major MODY gene loci remaining to be identified using SNP linkage analysis in Japanese. Whole-exome sequencing was performed with seven families with typical MODY. Candidates for novel MODY genes were examined combined with in silico network analysis. Some peaks were found only in either parametric or non-parametric analysis; however, none of these peaks showed a LOD score greater than 3.7, which is approved to be the significance threshold of evidence for linkage. Exome sequencing revealed that three mutated genes were common among 3 families and 42 mutated genes were common in two families. Only one of these genes, MYO5A, having rare amino acid mutations p.R849Q and p.V1601G, was involved in the biological network of known MODY genes through the intermediary of the INS. Although only one promising candidate gene, MYO5A, was identified, no novel, high penetrant MODY genes might remain to be found in Japanese MODY.

    Full Text Available Purpose. This article is devoted to the analysis of author-specific adjectives as neologisms found in texts by contemporary poetesses. The author aims to both define derivational models for the formation of IAN adjectives and identify the features of the functioning of adjectives in the text. Methodology. The method of the system scientific description is used in the work, implying the use of the methods of multi-aspect systematization of author-specific neologisms in accordance with the research task. Comparative-comparative method, implemented in observation, comparison and theoretical interpretation of the results of the new language material analysis, allows drawing conclusions upon carrying out the research. Results. In the course of the conducted research it was revealed that author-specific adjectives, found in the texts by V. Polozkova, A. Kudryasheva, D. Balyko, A. Rivelote represent the most numerous group of authorial neologisms. Having been created by productive models of addition, suffixation and prefixation, these lexemes express new semantic nuances in poetic texts, thus reflecting the special state of the persona. Practical implications. The results of this study can be used at university in the pedagogical practice of language teachers in the framework of studying Neology as an academic discipline as well as in analyzing contemporary poetry.

    2006-01-01

    Purpose: To assess prospectively how often contacts are found between the trigeminal nerve and arteries or veins in the perimesencephalic cistern via MRI in normal volunteers. Materials and methods: 48 volunteers without a history of trigeminal neuralgia were examined prospectively (MRI at 1.5T; T2-CISS sequence, coronal orientation, 0.9 mm slice thickness). Two radiologists decided by consensus whether there was a nerve-vessel contact in the perimesencephalic cistern. Results: In 27% of the volunteers, no contact was found between the trigeminal nerve and regional vessels, while in 73%, such a contact was present. In 61% of the cases, the offending vessel was an artery, in 39%, it was a vein. In 2 volunteers, a deformation of the nerve was noted. Conclusion: Contrary to what has been suggested by retrospective studies, the majority of normal volunteers, if studied prospectively, do show a contact between the trigeminal nerve and local vessels. A close proximity between the nerve and regional vessels is thus normal and is not necessarily proof of a pathological nerve-vessel conflict. (orig.)

    Feeding raw meat-based diets (RMBDs) to companion animals has become increasingly popular. Since these diets may be contaminated with bacteria and parasites, they may pose a risk to both animal and human health. The purpose of this study was to test for the presence of zoonotic bacterial and parasitic pathogens in Dutch commercial RMBDs. We analysed 35 commercial frozen RMBDs from eight different brands. Escherichia coli serotype O157:H7 was isolated from eight products (23 per cent) and extended-spectrum beta-lactamases-producing E coli was found in 28 products (80 per cent). Listeria monocytogenes was present in 19 products (54 per cent), other Listeria species in 15 products (43 per cent) and Salmonella species in seven products (20 per cent). Concerning parasites, four products (11 per cent) contained Sarcocystis cruzi and another four (11 per cent) S tenella In two products (6 per cent) Toxoplasma gondii was found. The results of this study demonstrate the presence of potential zoonotic pathogens in frozen RMBDs that may be a possible source of bacterial infections in pet animals and if transmitted pose a risk for human beings. If non-frozen meat is fed, parasitic infections are also possible. Pet owners should therefore be informed about the risks associated with feeding their animals RMBDs. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    The founding of ISOTT was based upon the blending of Medical and Engineering sciences. This occurrence is portrayed by the Shamattawa, the joining of the Chippewa and Flambeau rivers. Beginning with Carl Scheele's discovery of oxygen, the medical sciences advanced the knowledge of its importance to physiological phenomena. Meanwhile, engineering science was evolving as a mathematical discipline used to define systems quantitatively from basic principles. In particular, Adolf Fick's employment of a gradient led to the formalization of transport phenomena. These two rivers of knowledge were blended to found ISOTT at Clemson/Charleston, South Carolina, USA, in 1973.The establishment of our society with a mission to support the collaborative work of medical scientists, clinicians and all disciplines of engineering was a supporting step in the evolution of bioengineering. Traditional engineers typically worked in areas not requiring knowledge of biology or the life sciences. By encouraging collaboration between medical science and traditional engineering, our society became one of the forerunners in establishing bioengineering as the fifth traditional discipline of engineering.

    Glasses in forms of ornament and decorative objects have been found in Thailand for several hundred years. The mosaic glass used in this work was only one piece that excavated at Phu Khao thong archaeological site in Ranong Province, southern area of Thailand. Micro-beam X-ray fluorescence spectroscopy (μ-XRF) based on synchrotron radiation was firstly carried out to analyze its elemental composition and distribution. Scanning electron microscope coupled with energy dispersive X-ray fluorescence spectroscopy (SEM-EDS) and (PIXE) were also used to characterize the composition. The main composition of this mosaic glass sample found in Thailand was a lead-based silicate glass. The colorations were affected from transition metals, especially iron, copper and manganese. It was shown that although it look-liked the same, but the main composition was differ to that of Persia and South Asia, especially the lead content. However, it demonstrated the long distance trade or exchange network of the ancient time.

    To define variations of the depressor septi muscle in Iranians; to provide guidance for modification of this muscle during rhinoplasty in patients with an active muscle and short upper lip; and to correlate our findings with our clinical experience to develop the applied algorithms. This study was conducted by dissecting 82 depressor septi nasi muscles in 41 Iranian cadavers. Origin and insertion points of each muscle were studied. Three variations were found in muscle insertion points: periosteal, orbicularis oris, and floating. Forty-four percent of the muscles were inserted into the periosteum of the maxilla (n = 36); 39% of muscles were inserted into the orbicularis oris muscle (n = 32); and 17% were diminutive or floating (n = 14). Periosteal insertion was thicker and stronger than the other variations. In all cadavers, the origin of the muscle was medial crus of alar cartilage and caudal of the nasal septum. This cadaveric dissection showed that the percentage of depressor septi muscle insertions is not similar to that found in other surveys. In this study, periosteal insertion of the depressor septi muscle was the most common variation.

    Full Text Available Zoanthids (Anthozoa, Hexacorallia are colonial anemones that contain one of the deadliest toxins ever discovered, palytoxin (LD(50 in mice 300 ng/kg, but it is generally believed that highly toxic species are not sold in the home aquarium trade. We previously showed that an unintentionally introduced zoanthid in a home aquarium contained high concentrations of palytoxin and was likely responsible for a severe respiratory reaction when an individual attempted to eliminate the contaminant colonies using boiling water. To assess the availability and potential exposure of palytoxin to marine aquarium hobbyists, we analyzed zoanthid samples collected from local aquarium stores for palytoxin using liquid chromatography and high resolution mass spectrometry and attempted to identify the specimens through genetic analysis of 16S and cytochrome c oxidase 1 (COI markers. We found four specimens of the same apparent species of zoanthid, that we described previously to be responsible for a severe respiratory reaction in a home aquarium, to be available in three aquarium stores in the Washington D.C. area. We found all of these specimens (n = 4 to be highly toxic with palytoxin or palytoxin-like compounds (range 0.5-3.5 mg crude toxin/g zoanthid. One of the most potent non-protein compounds ever discovered is present in dangerous quantities in a select species of zoanthid commonly sold in the home aquarium trade.

    Are molecular pathways reflecting the biology of small for gestational age (SGA) neonates preserved in umbilical cord-derived mesenchymal stem cells (MSCs)? MSCs from SGA newborns were found to express an altered EGR-1-dependent gene network involved in the regulation of cell proliferation and oxidative stress. Individuals with suboptimal intrauterine development are at greater risk of metabolic diseases such as type II diabetes, obesity and cardiovascular disease. Umbilical cords (n = 283) from the GUSTO (growing up in Singapore towards healthy outcomes) birth cohort study, and primary MSC isolates established from SGA and matched control cases (n = 6 per group), were subjected to gene expression analysis and candidate genes were studied for functional validation. Umbilical cord specimens were derived from babies born at the National University Hospital (NUH) in Singapore. Local ethical approval was obtained. MSC isolates were established in Wharton's jelly and molecular analysis was conducted by gene expression microarrays and RT-PCR. Cells from SGA and control groups were compared in the presence and absence of insulin and candidate gene function was studied via siRNA-mediated gene knockdown and over-expression experiments in MSCs. Using repeated measure ANOVAs, proliferation rates of MSCs isolated from SGA neonates were found to be significantly increased (P < 0.01). In the absence of insulin, EGR-1 levels were found to be significantly reduced in the group of SGA-derived MSCs, whereas EGR-1 expression was found to be up-regulated in the same group in the presence of insulin (P < 0.01). EGR-1 was found to induce expression of COX-2 in the SGA group (P < 0.01) and both, EGR-1 and COX-2 stimulated glucose uptake in MSCs (P < 0.01). EGR-1 and COX-2 levels were associated in whole umbilical cords (n = 283, P < 0.01) and EGR-1 positively correlated with abdominal circumference and birthweight (n = 91, P < 0.01 and n = 91, P < 0.01).

    . By differencing within identical twin pair we are able to take heritable endowments transmitted from parent to child into account. For all outcomes OLS is found to be upward biased. Father schooling is found to have no causal effect on infant and early childhood health. Mother schooling increases birth weight...... and the probability of high school completion. For older cohorts, we are able to replicate the findings of Behrman & Rosenzweig (2002) that fathers' schooling has a positive causal effect on child schooling but mothers' does not.

    2013-01-01

    This paper describes the founding of the Revue Philosophique de la France et de l'Étranger by Théodule Ribot (1839-1916) in 1876. Like the English journal Mind, which was launched the same year, this journal introduced the new scientific psychology to France. Its founding increased Ribot's scientific credibility in psychology and led him to be regarded as the most distinguished French specialist in the field. First, we review the state of French philosophy at the time of the journal's founding, focusing on the three main French schools of thought in philosophy and on their relations with psychology. Second, after analyzing the preface written by Ribot in the first issue of the Revue Philosophique, we examine how the journal was received in French philosophical circles. Finally, we discuss its subsequent history, highlighting its founder's promotion of new ideas in psychology. © 2012 Wiley Periodicals, Inc.

    1989-01-01

    In 28 newly diagnosed type 2 diabetic patients (insulin-independent), computerized tomography (CT) was used to determine the density of the pancreas and the kidneys, densities of the liver, spleen and blood in the abdominal aorta, and to investigate pathological changes in the tissues mentioned above. The results were correlated with laboratory findings. The following changes were found: decreased density of the pancreas (29.4 H) and the liver (49.1 H) and increased density of the spleen (56.3 H) and blood in the abdominal aorta (43.7 H). The decreased density of the pancreas appears to be connected with disorders of lipoprotein metabolism. The decreased liver density was related to increased energy intake by food and to overweight evaluated by Broc's index. Other CT findings in the newly diagnosed type 2 diabetics (changes in the size of the pancreas, and kidneys, kidney cysts, nephrolithiasis, sclerotic plaques on aorta) were not significant.

    Full Text Available Hylarana chalconota is a cryptic species of frog endemic to Java Island [1]. This species is small with long legs, and brown skin. The Snout-Vent Length (SVL ranges between 30-40 mm for male and 45-65 mm for female. [4] Reports the existence of this species in State University of Malang, which was not found in 1995 [5]. Sampel #1 displays spots in its skin, which does not exist in sample #2. To reveal the haplotype diversity of COI gene in this species, we analyzed Cytochrome-c oxidase subunit-1 (COI sequences of both samples. Using a pair of primers according to [6] both samples had 604 bp and 574 bp fragment length, respectively. These fragments showed polymorphism; with mutation position in sites 104, 105, and 124. Based on this result, we suggest that the two samples share a different haplotypes, proposed as UM1 and UM2.

    We investigated possible sex differences in the development of locomotor activity in rats treated neonatally with desmethylimipramine (DMI) followed by intraventricular 6-hydroxydopamine (6-HDA). In addition, the locomotor response to the stimulant caffeine was investigated in the male rats after they had reached adulthood. Both male and female 6-HDA-treated rats exhibited increased activity relative to controls. No sex differences were seen in either the development or magnitude of this effect. Male rats were used to determine the dose effects function for caffeine (0.5, 5, 15, 30 mg/kg) on locomotor activity. Control rats exhibited increased locomotor activity whereas 6-HDA-treated rats showed no increases with any dose of caffeine. Large decreases in the dopamine content of the olfactory tubercle (-88%, -82%), nucleus accumbens (-96%, -95%), and striatum (-99%, -99%) were found in both male and female rats. Choline acetyltransferase and glutamic acid decarboxylase activities were unchanged.

    The deuterium content of the constitutional and interlayer water extracted from the clay minerals (illite, montmorillonite, interstratified illite-montmorillonite mineral, kaolinite, halloysite) constituting the clay veins found in the granitic rocks in Hiroshima Prefecture was measured. The clay minerals were heated at 270 deg C to extract the interlayer water, then heated to 1,400 or 1,500 deg C to extract the constitutional water. The deuterium content of the local surface water collected from sampling points was measured. In the clay veins formed along perpendicular joints, the constituent clay minerals change from lower to upper part: illite → montmorillonite → kaolinite → halloysite. The deuterium content values of the constitutional water for illite and montmorillonite were estimated to be -67 to -69% and -86 to -89%, respectively. The deuterium content values of the constitutional water for halloysite range from -68 to -80% and for kaolinite from -63 to -67%. (J.P.N.)

    In 1918, the first issue of the American Journal of Physical Anthropology was prepared and distributed by Aleš Hrdlička, the Curator of Physical Anthropology at the Smithsonian Institution. This was a singular act, both in the general and specific sense. It was the first journal of physical anthropology published in the United States, and it was a sole effort by Hrdlička, who was committed to promoting and recognizing physical anthropology as a new science in America. On this 100th anniversary of the founding of the journal, Hrdlička's efforts were successful: physical/biological anthropology is a strong and timely discipline that represents a major area of scientific research today. © 2018 Wiley Periodicals, Inc.

Compared with a control group of 2000 diseased falcons without evidence of aspergillosis, the prevalence of Babesia shortti, CFIDS, Mannheimia (Pastorella haemolytica, Escherichia coli, and falcon herpes virus infection was conspicuously higher in association with aspergillosis. These entities may be considered suitable candidates as predisposing factors for the mycosis.

    2013-10-01

    Examining the meanings of the experiences of advanced practice nurses (APNs) who chose to work with older adults and why they continue to work with this population was the focus of this hermeneutic qualitative research study. Twelve geriatric APNs currently practicing in two South Central states were interviewed using an open-ended interview guide. Using Gadamerian hermeneutics, the researchers identified Gerontology Found Me as the significant expression that reflected the fundamental meaning of the experience as a whole. Four themes emerged that further described the meanings of the participants' personal, educational, and professional experiences: Becoming a Gerontology Nurse, Being a Gerontology Nurse, Belonging to Gerontology, and Bringing Others to Gerontology. This study concluded that APNs' personal and professional experiences were more influential than educational experiences to become geriatric nurses, and having these personal and professional experiences of being in relationship with older individuals further contributed to their choice of gerontology.

    During our screening of tropical plants for endophyte microorganisms, a Xylareaceous fungus was found living on the internal part of Sapindus saponaria fruits. The fruits of S. saponaria accumulate great amounts of triterpenoidal and sesquiterpenoidal saponins. The saponin 3-O-({beta}-D-xylopyranosyl)-(1{yields}3)-{alpha}-L -rhamnopyranosyl-(1{yields}2)-{alpha}-L-arabinopyranosyl-hederagenin was isolated using chromatographic methods, after alkaline hydrolysis of the crude extract obtained from S. saponaria fruits and added to the culture medium used to grows the fungus. A new saponin was isolated from this experiment by preparative scale HPLC and characterized as a 22{alpha}-hydroxy derivative. The structure of this hydroxylated saponin was elucidated based on interpretation of MS/MS data and NMR spectra. (author)

    2005-01-01

    This study evaluated in vitro the antimicrobial activity of rough extracts from leaves of Arctium lappa and their phases. The following microorganisms, commonly found in the oral cavity, specifically in endodontic infections, were used: Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis and Candida albicans. The agar-diffusion method allowed detection of the hexanic phase as an inhibitor of microbial growth. Bioautographic assays identified antimicrobial substances in the extract. The results showed the existence, in the rough hexanic phase and in its fractions, of constituents that have retention factors (Rf) in three distinct zones, thereby suggesting the presence of active constituents with chemical structures of different polarities that exhibited specificity against the target microorganisms. It may be concluded that the Arctium lappa constituents exhibited a great microbial inhibition potential against the tested endodontic pathogens.

    2013-01-01

    The Archive Effect: Found Footage and the Audiovisual Experience of History examines the problems of representation inherent in the appropriation of archival film and video footage for historical purposes. Baron analyses the way in which the meanings of archival documents are modified when they are placed in new texts and contexts, constructing the viewer's experience of and relationship to the past they portray. Rethinking the notion of the archival document in terms of its reception and the spectatorial experiences it generates, she explores the 'archive effect' as it is produced across the genres of documentary, mockumentary, experimental, and fiction films. This engaging work discusses how, for better or for worse, the archive effect is mobilized to create new histories, alternative histories, and misreadings of history. The book covers a multitude of contemporary cultural artefacts including fiction films like Zelig, Forrest Gump and JFK, mockumentaries such as The Blair Witch Project and Forgotten Silve...

    2014-01-01

    This paper presents the first part of a state of the art review on the No Fault Found (NFF) phenomenon. The aim has been to compile a systematic reference point for burgeoning NFF literature, and to provide a comprehensive overview for gaining an understanding of NFF knowledge and concepts. Increasing systems complexities have seen a rise in the number of unknown failures that are being reported during operational service. Units tagged as ‘NFF’ are evidence that a serviceable component was removed, and attempts to troubleshoot the root cause have been unsuccessful. There are many reasons on how these failures manifest themselves and these papers describe the prominent issues that have persisted across a variety of industrial applications and processes for decades. This article, in particular, deals with the impact of NFF from an organizational culture and human factors point of view. It also highlights recent developments in NFF standards, its financial implications and safety concerns

    2014-01-01

    This is the second half of a two paper series covering aspects of the no fault found (NFF) phenomenon, which is highly challenging and is becoming even more important due to increasing complexity and criticality of technical systems. Part 1 introduced the fundamental concept of unknown failures from an organizational, behavioral and cultural stand point. It also reported an industrial outlook to the problem, recent procedural standards, whilst discussing the financial implications and safety concerns. In this issue, the authors examine the technical aspects, reviewing the common causes of NFF failures in electronic, software and mechanical systems. This is followed by a survey on technological techniques actively being used to reduce the consequence of such instances. After discussing improvements in testability, the article identifies gaps in literature and points out the core areas that should be focused in the future. Special attention is paid to the recent trends on knowledge sharing and troubleshooting tools; with potential research on technical diagnosis being enumerated

      Since the ban of tri-butyl tin, other various alternative antifouling agents have been used. In this study, the contamination levels from these antifouling agents were examined in the main harbors in Korea. The sampled harbors were classified into four types and the levels of contamination from the antifouling agents were analyzed. The highest degree of contamination was found in the big harbors, followed by the fishing harbors, harbors near agricultural areas, and military and coast guard harbors. In addition, an increase in the number of ships that entered the ports significantly influenced the contamination by the antifouling agents. Correlation analysis was conducted to characterize the alternative antifouling agents. The results revealed strong correlations between the dichlofluanid and chlorothalonil, and between the chlorothalonil and TCMTB, because unlike Irgarol 1051 and SEA-NINE 211, which are used only as antifouling agents, chlorothalonil, dichlofluanid, and TCMTB are also used in agriculture.

    Our archival researches at the Royal Society reveal that a small envelope attached to a 1675 letter from an Antwerp apothecary, A. Boutens, contained a sample of the 'Ludus' prepared as a remedy for the 'stone disease' then sweeping through Europe, which was first announced in J. B. van Helmont's De lithiasi (1644). After examining the fascination with the medical use of the Ludus (which required the 'alkahest' for its preparation) and the tenacious efforts to procure it, we trace the fortunae of two other ludi in England, brought to and offered by Francis Mercurius van Helmont during his English sojourn. Both eventually found their way to the geologist John Woodward, one of them through Sir Isaac Newton. Finally we show how the allure of the Ludus helmontii vanished, with transformations in mineral analysis and reclassifications from Woodward to John Hill.

    Infectious diarrhea is seen with increasing frequency in general practice. The main reason is growing tourism in countries with conditions of public health different from ours, where the incidence of enteropathogenic parasites is higher. To obtain an overview of these parasites, the results of 23,276 stool samples from patients in general practice throughout Switzerland were analyzed. Protozoa were found in 32% of samples (4.6% pathogenic protozoa, 24% facultative pathogenic protozoa and 3.4% apathogenic protozoa). Helminths were demonstrated in 2.9% of stool samples. The helminth spectrum covered 15 types, with Trichuris trichiuria predominating (one third). 8% of the Swiss population travel every year to areas with a higher diarrhea incidence. A proportion of these subjects constitute a health risk on their return to Switzerland. They chiefly consist of people working in, or living with someone working in, the food industry. Specific parasitologic diagnosis of diarrhea contributes significantly to reducing this risk.

    Full Text Available Inside cells, viruses build specialized compartments for replication and morphogenesis. We observed that virus release associates with specific structures found on the surface of mammalian cells. Cultured adherent cells were infected with a bunyavirus and processed for oriented sectioning and transmission electron microscopy. Imaging of cell basal regions showed sophisticated multilamellar structures (MLS and extracellular filament bundles with attached viruses. Correlative light and electron microscopy confirmed that both MLS and filaments proliferated during the maximum egress of new viruses. MLS dimensions and structure were reminiscent of those reported for the nanostructures on gecko fingertips, which are responsible for the extraordinary attachment capacity of these lizards. As infected cells with MLS were more resistant to detachment than control cells, we propose an adhesive function for these structures, which would compensate for the loss of adherence during release of new virus progeny.

    Koenigs-Knorr glycosylation of acceptors with more than one free hydroxyl group by 2,3,5,6-tetrabenzoyl galactofuranosyl bromide was performed using diphenylborinic acid 2-aminoethyl ester (DPBA) as inducer of regioselectivity. High regioselectivity for the glycosylation on the equatorial hydroxyl group of the acceptor was obtained thanks to the transient formation of a borinate adduct of the corresponding 1,2-cis diol. Nevertheless formation of orthoester byproducts hampered the efficiency of the method. Interestingly electron-withdrawing groups on O-6 or on C-1 of the acceptor displaced the reaction in favor of the desired galactofuranosyl containing disaccharide. The best yield was obtained for the furanosylation of p-nitrophenyl 6-O-acetyl mannopyranoside. Precursors of other disaccharides, found in the glycocalix of some pathogens, were synthesized according to the same protocol with yields ranging from 45 to 86%. This is a good alternative for the synthesis of biologically relevant glycoconjugates.

    Animal cruelty is defined as a deliberate action that causes pain and suffering to an animal. In Brazil, legislation known as the Environmental Crimes Law states that cruelty toward all animal species is criminal in nature. From 644 domestic cats necropsied between January 1998 and December 2009, 191 (29.66%) presented lesions highly suggestive of animal cruelty. The main necroscopic finding was exogenous carbamate poisoning (75.39%) followed by blunt-force trauma (21.99%). Cats from 7 months to 2 years of age were the most affected (50.79%). In Brazil, violence is a public health problem and there is a high prevalence of domestic violence. Therefore, even if laws provide for animal welfare and protection, animals are common targets for violent acts. Within a context of social violence, cruelty toward animals is an important parameter to be considered, and the non-accidental lesions that were found are evidence of malicious actions.

  18. Who founded Buddhism? Notes on the psychological effectiveness of religious objects.

    Black, David M

    2017-04-01

    Starting with an outline of Buddhist history from a psychoanalytic perspective, this paper uses ideas from philosophy and psychoanalysis to consider the nature of the psychological effectiveness of religious objects. It suggests that the development of the devotional cult of Buddhas 'without form' such as Amitābha, at-first-glance surprising when juxtaposed with the founding vision of Gautama Siddhartha, tells us a great deal about the psychological needs that impel the evolution of religious thinking. Distinguishing religious objects from mythological ones, it argues that 'religious objects' are, more specifically, allegorical objects that can be encountered in the second person; that these may not always be well described as 'illusion'; and that they may in some cases be better understood as providing opportunities for experience that, like the transference in psychoanalysis, may have far-reaching psychological impacts.

    Full Text Available Paper currency by its very nature is frequently transferred from one person to another and represents an important medium for human contact with-and potential exchange of-microbes. In this pilot study, we swabbed circulating $1 bills obtained from a New York City bank in February (Winter and June (Summer 2013 and used shotgun metagenomic sequencing to profile the communities found on their surface. Using basic culture conditions, we also tested whether viable microbes could be recovered from bills.Shotgun metagenomics identified eukaryotes as the most abundant sequences on money, followed by bacteria, viruses and archaea. Eukaryotic assemblages were dominated by human, other metazoan and fungal taxa. The currency investigated harbored a diverse microbial population that was dominated by human skin and oral commensals, including Propionibacterium acnes, Staphylococcus epidermidis and Micrococcus luteus. Other taxa detected not associated with humans included Lactococcus lactis and Streptococcus thermophilus, microbes typically associated with dairy production and fermentation. Culturing results indicated that viable microbes can be isolated from paper currency.We conducted the first metagenomic characterization of the surface of paper money in the United States, establishing a baseline for microbes found on $1 bills circulating in New York City. Our results suggest that money amalgamates DNA from sources inhabiting the human microbiome, food, and other environmental inputs, some of which can be recovered as viable organisms. These monetary communities may be maintained through contact with human skin, and DNA obtained from money may provide a record of human behavior and health. Understanding these microbial profiles is especially relevant to public health as money could potentially mediate interpersonal transfer of microbes.

    Full Text Available Abstract Background Ocular albinism type 1 (OA1 is an X-linked ocular disorder characterized by a severe reduction in visual acuity, nystagmus, hypopigmentation of the retinal pigmented epithelium, foveal hypoplasia, macromelanosomes in pigmented skin and eye cells, and misrouting of the optical tracts. This disease is primarily caused by mutations in the OA1 gene. Methods The ophthalmologic phenotype of the patients and their family members was characterized. We screened for mutations in the OA1 gene by direct sequencing of the nine PCR-amplified exons, and for genomic deletions by PCR-amplification of large DNA fragments. Results We sequenced the nine exons of the OA1 gene in 72 individuals and found ten different mutations in seven unrelated families and three sporadic cases. The ten mutations include an amino acid substitution and a premature stop codon previously reported by our team, and eight previously unidentified mutations: three amino acid substitutions, a duplication, a deletion, an insertion and two splice-site mutations. The use of a novel Taq polymerase enabled us to amplify large genomic fragments covering the OA1 gene. and to detect very likely six distinct large deletions. Furthermore, we were able to confirm that there was no deletion in twenty one patients where no mutation had been found. Conclusion The identified mutations affect highly conserved amino acids, cause frameshifts or alternative splicing, thus affecting folding of the OA1 G protein coupled receptor, interactions of OA1 with its G protein and/or binding with its ligand.

    The present program of research synthesizes the findings from three studies in line with two goals. First, the present research explores how the oil and gas industry is performing at risk mitigation in terms of finding and fixing errors when they occur. Second, the present research explores what factors in the work environment relate to a risk-accommodating environment. Study 1 presents a descriptive evaluation of high-consequence incidents at 34 oil and gas companies over a 12-month period (N = 873), especially in terms of those companies' effectiveness at investigating and fixing errors. The analysis found that most investigations were fair in terms of quality (mean = 75.50%), with a smaller proportion that were weak (mean = 11.40%) or strong (mean = 13.24%). Furthermore, most companies took at least one corrective action for high-consequence incidents, but few of these corrective actions were confirmed as having been completed (mean = 13.77%). In fact, most corrective actions were secondary interim administrative controls (e.g., having a safety meeting) rather than fair or strong controls (e.g., training, engineering elimination). Study 2a found that several environmental factors explain the 56.41% variance in safety, including management's disengagement from safety concerns, finding and fixing errors, safety management system effectiveness, training, employee safety, procedures, and a production-over-safety culture. Qualitative results from Study 2b suggest that a compliance-based culture of adhering to liability concerns, out-group blame, and a production-over-safety orientation may all impede safety effectiveness. © 2016 Society for Risk Analysis.

    Peri-implantitis is a disease characterized by soft tissue inflammation and continued loss of supporting bone, which can result in implant failure. Peri-implantitis is a multifactorial disease, and one of its triggering factors may be the presence of excess cement in the soft tissues surrounding an implant. This descriptive study evaluated the composition of foreign particles from 36 human biopsy specimens with 19 specimens selected for analysis. The biopsy specimens were obtained from soft tissues affected by peri-implantitis around cement-retained implant crowns and compared with the elemental composition of commercial luting cement. Nineteen biopsy specimens were chosen for the comparison, and five test cements (TempBond, Telio, Premier Implant Cement, Intermediate Restorative Material, and Relyx) were analyzed using scanning electron microscopy equipped with energy dispersive x-ray spectroscopy. This enabled the identification of the chemical composition of foreign particles embedded in the tissue specimens and the composition of the five cements. Statistical analysis was conducted using classification trees to pair the particles present in each specimen with the known cements. The particles in each biopsy specimen could be associated with one of the commercial cements with a level of probability ranging between .79 and 1. TempBond particles were found in one biopsy specimen, Telio particles in seven, Premier Implant Cement particles in four, Relyx particles in four, and Intermediate Restorative Material particles in three. Particles found in human soft tissue biopsy specimens around implants affected by peri-implant disease were associated with five commercially available dental cements.

    Fungal infection in plant leads to use of many hazardous antifungal chemicals. Alternative to these chemicals, defense related antifungal proteins can be used in case of fungal diseases. An experiment was done in two varieties of edible radish (Raphanus sativus var. Pyuthane Raato and Raphanus sativus var. all season) with aims to produce defense protein within the plant, to identify and perform molecular characterization of those antifungal proteins. The next aim was to compare the antifungal property of those proteins with commercially available synthetic pesticides. Both varieties of radish were infected with fungi (Alternaria alternata and Fusarium oxysporum). Protein samples were isolated from leaves following the standard protocol as described for β-glucuronidase (GUS) assay and were run along with the standard protein marker of 10-250kDa in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) to identify and molecularly characterize them. An additional band in the range of 37-50kDa was observed in the fungal infected samples, which was not seen on uninfected samples. The antifungal assay was carried out for every sample in 96 wells microtitre plate. The extracted protein samples from fungal inoculated plants showed the significant inhibition of fungal growth compared to other samples. On the basis of molecular weight and their antifungal properties, the protein samples from the fungal infected plant were found to be PR2 (Glucanase) and PR3 (Chitinase). Defense related proteins were successfully produced in two varieties of radish found in Nepal. The use of such biologically produced proteins may reduce the use of biologically harmful synthetic pesticides.

Morphometric variations of three species of harvested cephalopods found in northern sea of Aceh Province, Indonesia. Biodiversitas 15: 142-146. The purpose of the present study was to evaluate the morphometrics of three harvested cephalopods, Sepioteuthis lessoniana, Sepia officinalis and Uroteuthis sp. found in northern sea of Aceh Province, Indonesia. Sampling was conducted for six months from July to December 2012 in one week interval. A total of 318 cephalopods; 139 Sepioteuthis lessoniana, 139 Uroteuthis sp. and 40 Sepia officinalis were analyzed for morphometric study and 13 anatomical characters were measured to the nearest 0.01 mm using a digital calipers. Morphometric measurements were significantly different between the different species of cephalopods (ANOVA, p<0.05. S. officinalis differed in six morphological characters (head length, head width, tentacles length, gladius width, rancis width and length from the squid species. Fin width and length were significantly greater in S. lessoniana than in S. officinalis and Uroteuthis sp. On the other hand, Uroteuthis sp. had significantly greater mantle lengths, standard lengths and gladius lengths than the other two cephalopod species (Duncan Test, p<0.05. However, fin width was similar between S. lessoniana and Uroteuthis sp., while eye diameter was similar between S. officinalis and Uroteuthis sp. A Discriminant Function Analysis scatter plot successfully discriminated the three species indicating significant differences in morphological variation. This analysis also indicates that morphometrically, S. lessoniana and S. officinalis are more similar to each other despite being in different orders.

    Full Text Available The Jinchuan yak is a new yak population identified in Sichuan, China. This population has a special anatomical characteristic: an additional pair of ribs compared with other yak breeds. The genetic structure of this population is unknown. In the present study, we investigated the maternal phylogeny of this special yak population using the mitochondrial DNA variation. A total of 23 Jinchuan yaks were sequenced for a 823-bp fragment of D-loop control region and three individuals were sequenced for the whole mtDNA genome with a length of 16,371-bp. To compare with the data from other yaks, we extracted sequence data from Genebank, including D-loop of 398 yaks (from 12 breeds and 55 wild yaks, and whole mitochondrial genomes of 53 yaks (from 12 breeds and 21 wild yaks. A total of 127 haplotypes were defined, based on the D-loop data. Thirteen haplotypes were defined from 23 mtDNA D-loop sequences of Jinchuan yaks, six of which were shared only by Jinchuan, and one was shared by Jinchuan and wild yaks. The Jinquan yaks were found to carry clades A and B from lineage I and clade C of lineage II, respectively. It was also suggested that the Jinchuan population has no distinct different phylogenetic relationship in maternal inheritance with other breeds of yak. The highly haplotype diversity of the Pali breed, Jinchuan population, Maiwa breed and Jiulong breed suggested that the yak was first domesticated from wild yaks in the middle Himalayan region and the northern Hengduan Mountains. The special anatomic characteristic that we found in the Jinchuan population needs further studies based on nuclear data.

    A common and unfortunate cause for heat stroke-related deaths in children is entrapment in closed vehicles. The aim of this study was to analyze the pathological consequences of such grave events. Autopsy reports of all children that were brought to a national forensic medicine center after being found dead in closed vehicles over a 21-year period (1995-2015) were reviewed. Data extracted were the circumstances of the events, child age, sex, height and weight, time, date and duration of entrapment, and environmental temperatures at the time of entrapment and the autopsy findings. Eight deceased children were brought to the forensic medicine center for autopsy, and seven families consented to the procedure. Autopsy findings included diffuse petechiae and hemorrhages of serosal membranes (n = 7/7) and lung congestion (n = 3/7). Typical autopsy findings following classical heat stroke in children include diffuse petechiae and hemorrhages and lung involvement. These findings are similar to those reported in adults that had died following exertional heat stroke-a very different mechanism of heat accumulation. Prevention of future events can possibly be obtained by public education on the rapid heating of closed vehicles, the vulnerability of children to heat, and the caregiver role in child entrapment. • A common and unfortunate cause for heat stroke-related deaths in children is entrapment in closed vehicles. The pathological consequences of such grave events have not been previously reported. What is New: • This study is the first to describe autopsy findings from children who were found dead in parked cars. • Autopsy findings included diffuse petechiae hemorrhages of serosal membranes and lung congestion. • These findings are identical to those seen in adults following exertional heat stroke.

    Highlights: • Corrosion of brass in NaCl concentrations found in eccrine sweat was investigated. • Concentrations < 0.2 M produce a layer of mainly zinc oxide after 24 h. • A concentration of 0.2 M enables active corrosion of brass at room temperature. • 0.2 M NaCl gives both zinc and copper dissolution. • 24-h immersion of brass in 0.2 M NaCl gives an oxide film thickness of 1.3 nm. - Abstract: In this work, the corrosion properties of α phase brass immersed in concentrations of aqueous NaCl solutions that are typically found in eccrine fingerprint sweat and range between 0.01 M and 0.2 M have been analysed. Analysis methods employed were electrochemical techniques, X-ray photoelectron spectroscopy and optical profiling. For NaCl concentrations <0.2 M, active corrosion did not occur although, after a period of 24 h, a passivating layer of mainly zinc oxide formed. At a concentration of 0.2 M active corrosion did occur, with measured corrosion potentials consistent with both brass and copper dissolution. A 1 h contact time at this concentration (0.2 M) resulted in the formation of a zinc oxide passivating layer with the surface ratio of zinc oxide to copper oxide increasing with time. Film thickness was calculated to be of the order of 1.3 nm after 24 h contact. Formation of oxide layers on brass by fingerprint sweat as observed here may well have implications for the successful investigation of crime by the visualisation of corrosion fingerprint ridge patterns or the reduction of hospital environmental contamination by hand contact with brass objects such as door handles or taps.

    Full Text Available Attitudes toward traditional and chiropractic medicine were compared using Milgram's lost letter technique. A total of 192 letters were placed on the windshields of vehicles in parking lots at six restaurants and department stores in each of four quadrants of a medium-sized, Southeastern city. These letters were addressed to "Admissions" at either a fictitious Institute of Medicine or Institute of Chiropractic Care. Return addresses included either a male or a female name. Thus, those who found a lost letter were faced with the option of returning or not returning a letter from either a male or a female, addressed to an Institute of traditional or non-traditional medicine. After examining previous studies which had used the lost letter technique, numerous methodological improvements were implemented. For example, letters were randomly assigned to potential drop spots for each of 24 study locations (six study locations in each of four city quadrants, and a Latin square design was used to control for possible order effects in the four study conditions that were implemented. Nearly 65% of the letters (124 of 192 were returned. We found: 1 letters addressed to a fictitious Institute of Chiropractic Care were just as likely to be returned as those addressed to a fictitious Institute of Medicine; 2 letters with female return addresses were as likely to be returned as those with male return addresses; 3 there was no interaction between study conditions; 4 based on what was essentially a replication study, a comparison of the pattern of returns using the first and second cycle of lost letters (n = 96 for each cycle revealed an equivalent pattern of no-difference findings. DOI: 10.2458/azu_jmmss.v1i1.78

    MR imaging is used to assess iron overload in patients with hemoglobinopathies and in those who have undergone multiple blood transfusions. Sometimes splenic nodules are found incidentally on these examinations and this may cause diagnostic uncertainty. To determine the prevalence, imaging characteristics and evolution of splenic nodules found on MR imaging for iron overload evaluation. Retrospective review of all MR imaging examinations performed for iron overload assessment from 2005 to 2015 in a tertiary pediatric hospital. The presence of focal splenic nodules including number, size, signal characteristics and changes on follow-up MR imaging were recorded. Relevant patient clinical information including underlying hematological disease was also documented. A total of 318 patients had MR imaging for iron overload assessment. Of these, 25 (8%) had at least one incidental splenic nodule. Sickle cell disease was present in 22 patients (88%) and thalassemia in 3 (12%). On intermediate-weighted spin-echo images, the nodules had high signal intensity compared to the remainder of the spleen in 23 patients (92%) and low signal intensity in the remaining 2 (8%). In all patients (100%) the nodules showed progressive loss of signal intensity with increasing echo time values. Follow-up MR imaging was performed in 20 (80%) patients, which showed an increase in the size of the splenic nodules in 7 patients (35%) stability in 11 (55%) and a decrease in size in 2 (10%). It is not uncommon to find splenic nodules during MR evaluation of iron overload. In patients with sickle cell disease, most of these nodules are thought to represent preserved splenic tissue and appear hyperintense compared to the remainder of the spleen. They frequently remain stable on follow-up imaging, although about a third of them may show growth. Awareness of these nodules is important to avoid concern for potential malignancy and unnecessary investigations. (orig.)

    Cytochrome P450 monooxygenases (CYPs) usually overexpressed in resistant strain were found involved in oxidative detoxification of insecticides. In this study, an investigation was conducted to confirm if resistance irrelevant CYPs which were not overexpressed in resistant strain before, were capable of degrading insecticides. Three resistance irrelevant CYPs viz. CYP417A2v2, CYP425A1v2, and CYP4DJ1 from CYP4 family of Laodelphax striatellus were randomly selected for experiments. CYP417A2v2 and CYP425A1v2 were found expressed successfully in Sf9 cell line while CYP4DJ1 was not expressed successfully and out of two expressed CYPs, only CYP417A2v2 showed its efficient catalytic activity. For catalytic activity, three traditional model probe substrates and five insecticides were assayed. For the probe substrates screened, p -nitroanisole and ethoxycoumarin were preferentially metabolized by CYP417A2v2 (specific activity 3.76 ± 1.22 and 1.63 ± 0.37 nmol min -1  mg protein -1 , respectively) and they may be potential diagnostic probes for this enzyme. Among insecticides, only imidacloprid was efficiently degraded by CYP417A2v2. Incubation of imidacloprid with CYP417A2v2 of L. striatellus and subsequent HPLC, LC-MS, and MS/MS analysis revealed the formation of imidacloprid metabolites, that is, 4' or 5'hydroxy-imidacloprid by hydroxylation. This result implies the exemption of CYPs character that it is not always, all the CYPs degrading insecticides being selected and overexpressed in resistant strains and the degrading CYPs without mutations to upregulate could be candidates during insecticide resistance evolution. This characterization of individual insect CYPs in insecticide degradation can provide insight for better understand of insecticide resistance development.

    A direct observation of the thermal vibrations of Be metal was performed by the Maximum Entropy Method (MEM) using neutron single crystal data. In the previous study, the existence of the small but significant cubic anharmonicity of Be has been found by the conventional least squares refinement of the observed structure factors [Larsen, Lehmann and Merisalo (1980) Acta Cryst. A36, 159-163]. In the present study, the same data were used for the MEM analysis which are comprised of 48 reflections up to sinθ/λ = 1.41A -1 in order to obtain the high resolution nuclear density of Be without using any thermal vibrational model. It was directly visible in the MEM map that not only the cubic terms but also quartic anharmonicities exist in the thermal vibrations of Be nuclei. In order to evaluate thermal parameters of Be including anharmonic terms quantitatively, the least squares refinement of the effective one-particle potential (OPP) parameters up to quartic term was carried out by using the MEM nuclear densities around atomic sites as the data set to be fitted. It was found that the present treatment has a great advantage to decide the most appropriate model of OPP by visually comparing the model with MEM density map. As a result of the least squares refinement, the anharmonic thermal parameters are obtained as α 33 = -0.340(5)[eV/A 3 ], α 40 = 0, β 20 = 9.89(1)[eV/A 4 ] and γ 00 = 0. No other anharmonic term was significant. (author)

    MR imaging is used to assess iron overload in patients with hemoglobinopathies and in those who have undergone multiple blood transfusions. Sometimes splenic nodules are found incidentally on these examinations and this may cause diagnostic uncertainty. To determine the prevalence, imaging characteristics and evolution of splenic nodules found on MR imaging for iron overload evaluation. Retrospective review of all MR imaging examinations performed for iron overload assessment from 2005 to 2015 in a tertiary pediatric hospital. The presence of focal splenic nodules including number, size, signal characteristics and changes on follow-up MR imaging were recorded. Relevant patient clinical information including underlying hematological disease was also documented. A total of 318 patients had MR imaging for iron overload assessment. Of these, 25 (8%) had at least one incidental splenic nodule. Sickle cell disease was present in 22 patients (88%) and thalassemia in 3 (12%). On intermediate-weighted spin-echo images, the nodules had high signal intensity compared to the remainder of the spleen in 23 patients (92%) and low signal intensity in the remaining 2 (8%). In all patients (100%) the nodules showed progressive loss of signal intensity with increasing echo time values. Follow-up MR imaging was performed in 20 (80%) patients, which showed an increase in the size of the splenic nodules in 7 patients (35%) stability in 11 (55%) and a decrease in size in 2 (10%). It is not uncommon to find splenic nodules during MR evaluation of iron overload. In patients with sickle cell disease, most of these nodules are thought to represent preserved splenic tissue and appear hyperintense compared to the remainder of the spleen. They frequently remain stable on follow-up imaging, although about a third of them may show growth. Awareness of these nodules is important to avoid concern for potential malignancy and unnecessary investigations. (orig.)

    The purpose of this study was to identify the psychological themes found during the modified CARING at Columbia-Music Therapy (CAC-MT) program with refugee adolescents from North Korea. Nine students attending an alternative school participated in this study. Academically, students belong to an equivalent middle school level. Students participated in a music therapy program comprised of 25 sessions. A multiple case analysis was conducted to gather qualitative results. Students were found to be exposed to various psychosocially stressful life situations such as lack of social support system, family separation, academic difficulty, and economic hardship throughout their adaptation process to their new country. There were 5 common psychological themes--avoidance, distrust, loneliness, feelings of loss, and fear--found among the refugee students over the course of the CAC-MT treatment. For future research, studies with a larger sample size and differing types of session structure should be conducted to closely examine the effects of this program on refugee adolescents.

    1921-08-31

    Ten varieties of North American shellfish were examined for the occurrence of Cristispira in their styles. A cristispira was found in various numbers in Ostrea virginiana, Venus mercenaria, and Modiola modiolus, but none in Ensis americana, Mya arenaria, Mactra solidissima, Pecten irradians, Mytilus edulis, Fulgur canaliculatus, or Nassa obsoleta. Of 298 oysters, only 128 showed the crystalline styles, in which cristispiras were present in 99. Active cristispiras were found in 59 styles only and degenerated forms in the remaining 40. In 110 clams (Venus mercenaria) 70 styles were found, and only 8 of these contained cristispiras; 5 yielded active and the other 3 degenerated cristispiras. In 97 modiolas there were 73 styles, only 4 of which contained cristispiras. The physical properties of the crystalline styles of these shellfish varied considerably. The styles of the oysters were moderately soft, and when exposed to the air or mixed with sea water they underwent liquefaction, forming a clear, viscid material. The styles from clams and modiolas were opaque and were more firm, not easily crushed even in a mortar. The styles of the scallops were the most solid of all the styles examined. It happened that the softer the styles, the more frequent was the occurrence of the cristispira; in fact, no cristispira was detected in styles other than those of oysters, clams, and modiolas, of which oysters had the softest styles and the largest percentage of cristispira invasion. The following observations were made regarding the structure of the cristispira found in oysters. The body is a long, flexible cylinder, with blunt extremities, towards which the diameter gradually diminishes. In motion the body rapidly stretches and contracts, forming in the contracted state several serpentine undulations. A membranous appendage (Gross' crista) winds about the body throughout its entire length. The inner margin is in connection with the body, the outer margin is free and is distinctly

    2004-07-01

    In response to the report ''Investigation of Beryllium Exposure Cases Discovered at the North Las Vegas Facility of the National Nuclear Security Administration'', published by the U.S. Department of Energy (DOE), National Nuclear Security Administration (NNSA) in August 2003, Bechtel Nevada (BN) President and General Manager Dr. F. A. Tarantino appointed the Beryllium Investigation & Assessment Team (BIAT) to identify both the source and pathway for the beryllium found in the North Las Vegas (NLV) B-Complex. From September 8 to December 18, 2003, the BIAT investigated the pathway for beryllium and determined that a number of locations existed at the Nevada Test Site (NTS) which could have contained sufficient quantities of beryllium to result in contamination if transported. Operations performed in the B-1 Building as a result of characterization activities at the Engine Maintenance, Assembly, and Disassembly (EMAD); Reactor Maintenance, Assembly, and Disassembly (RMAD); Test Cells A and C; and the Central Support Facility in Area 25 had the greatest opportunity for transport of beryllium. Investigative monitoring and sampling was performed at these sites with subsequent transport of sample materials, equipment, and personnel from the NTS to the B-1 Building. The timeline established by the BIAT for potential transport of the beryllium contamination into the B-1 Building was from September 1997 through November 2002. Based on results of recently completed swipe sampling, no evidence of transport of beryllium from test areas has been confirmed. Results less than the DOE beryllium action level of 0.2 ???g/100 cm2 were noted for work support facilities located in Area 25. All of the identified sites in Area 25 worked within the B-1 tenant's residency timeline have been remediated. Legacy contaminants have either been disposed of or capped with clean borrow material. As such, no current opportunity exists for release or spread of beryllium

    Sauli Heikkilä

    2017-06-01

    Full Text Available The author of this essay, musician and founder of the Throat Singing Association of Finland (1997, tells the story of how an association of throat singing practitioners came to be in Finland, and how to teach this art to those wishing to learn it. The story also covers the author’s own musical preferences and his life-changing visit to a week-long workshop led by Boris Salchak from Tuva in 1995. Two years later, the author and other aficionados of Tuvan xöömei founded the Throat Singing Association and started holding festivals featuring invited Tuvan singers and throat singing courses. The author describes his collaboration with renowned Tuvan performers, as well as throat singing scholars from the USA, the Netherlands, UK, Italy, etc. The author holds that throat (or overtone singing is a special sound practice. Tuvan practices can be compared with similar techniques developed by indigenous peoples of Africa, North America, Japan and Tibet. Throat singing as a practice is closely linked to specific ancient worldviews of peoples and cultures living close to nature. Finns are also considered living in close proximity to nature, which may explain their partiality to throat signing. Dozens actively practice xöömei and hundreds have experienced it, which is a much larger percentage than in other European states. In the essay, the author also focuses on the throat singing courses he has been giving for a while and shares his observations of his students, their motivation, specific training techniques and adapting them to the desires and intentions of his students. He believes that almost everybody can learn singing, and most people can have a command of throat singing. The essay also covers the main problems that aspiring throat singers can face, as well as specific styles of the xöömei, concluding with the idea that it is impossible to master throat singing in a short period of time. The key to success is only found in regular and extensive

  18. The MUC1 extracellular domain subunit is found in nuclear speckles and associates with spliceosomes.

    Directory of Open Access Journals (Sweden)

    Full Text Available MUC1 is a large transmembrane glycoprotein and oncogene expressed by epithelial cells and overexpressed and underglycosylated in cancer cells. The MUC1 cytoplasmic subunit (MUC1-C can translocate to the nucleus and regulate gene expression. It is frequently assumed that the MUC1 extracellular subunit (MUC1-N does not enter the nucleus. Based on an unexpected observation that MUC1 extracellular domain antibody produced an apparently nucleus-associated staining pattern in trophoblasts, we have tested the hypothesis that MUC1-N is expressed inside the nucleus. Three different antibodies were used to identify MUC1-N in normal epithelial cells and tissues as well as in several cancer cell lines. The results of immunofluorescence and confocal microscopy analyses as well as subcellular fractionation, Western blotting, and siRNA/shRNA studies, confirm that MUC1-N is found within nuclei of all cell types examined. More detailed examination of its intranuclear distribution using a proximity ligation assay, subcellular fractionation, and immunoprecipitation suggests that MUC1-N is located in nuclear speckles (interchromatin granule clusters and closely associates with the spliceosome protein U2AF65. Nuclear localization of MUC1-N was abolished when cells were treated with RNase A and nuclear localization was altered when cells were incubated with the transcription inhibitor 5,6-dichloro-1-b-d-ribofuranosylbenzimidazole (DRB. While MUC1-N predominantly associated with speckles, MUC1-C was present in the nuclear matrix, nucleoli, and the nuclear periphery. In some nuclei, confocal microscopic analysis suggest that MUC1-C staining is located close to, but only partially overlaps, MUC1-N in speckles. However, only MUC1-N was found in isolated speckles by Western blotting. Also, MUC1-C and MUC1-N distributed differently during mitosis. These results suggest that MUC1-N translocates to the nucleus where it is expressed in nuclear speckles and that MUC1-N and MUC

    2001-01-01

    Habit surveys were carried out around four licensed nuclear sites to identify people who collect foodstuffs from the wild (so-called 'free foods'). In total, around 800 collectors were readily identified, most of whom collected more than one free food. The data indicated that estimates of higher than average doses could reasonably be based on the three foodstuffs of most importance. Foods were selected for further study on the basis of either the number of collectors or the amount consumed. The radionuclides of interest were identified using published information on the discharges from each site. The resultant average and higher than average doses were estimated using the site-specific habit data. For all sites, doses from the consumption of free foods were low and of no radiological importance. Assessments based solely on data for cultivated foods would not therefore have underestimated radiological impact significantly. However, given the wide utilisation of free foods found in this study, for rigorous assessments it would be prudent to take account of the consumption of foods from the wild. (author)

    An autopsy case of acute myelocytic leukemia preceded by hemopoietic dysplasia, presumably on a sequela to the atomic bomb in Hiroshima is reported. On admission, severe anemia and thrombocytosis were found and the bone marrow aspiration showed myeloid hyperplasia without definite maturation arrest. Mild to moderate eosinophilia and basophilia continued during the course of the disease, accompaning mild monocytosis 2 years later. Furthermore, he had the radical operation for the early gastric cancer in this preleukemic stage. After the administration of methenolone acetate (25 mg/day), severe anemia has dramatically improved, but leukocytosis with profound monocytosis persisted, and subsequently acute myelocytic leukemia developed. He died from an intracerebral bleeding due to an accidental trauma on the head. Autopsy findings disclosed the systemic leukemic infiltration. Repeated chromosome analyses revealed the mosaic karyotype of 46, XY/45, XY, -16 on admission, but it was 46, XY/46, XY, del (8) (p 12) in the overt leukemic phase. The granulopoietic colony forming capacity of bone marrow cells was already low one year before the onset of overt leukemia. This finding suggested that the existence of an abnormal clone could be predictable. In addition, the possible causative effect of the exposure to the atomic bomb in leukemogenesis in this case is discussed.

    Use of herbal dietary supplements by the public is common and has been happening for centuries. In the United States, the Food and Drug Administration has a limited scope of regulation over marketed herbal dietary supplements, which may contain toxic botanical compounds that pose a public health risk. While the Food and Drug Administration has made efforts to prohibit the sale of unsafe herbal dietary supplements, numerous reports have proliferated of adverse events due to these supplements. This literature review investigates bioactive plant compounds commonly used in herbal dietary supplements and their relative toxicities. Using primarily the National Library of Medicine journal database and SciFinder for current reports, 47 toxic compounds in 55 species from 46 plant families were found to demonstrate harmful effects due to hepatic, cardiovascular, central nervous system, and digestive system toxicity. This review further contributes a novel and comprehensive view of toxicity across the botanical dietary market, and investigates the toxicity of the top ten botanical dietary supplements purchased in the United States of America to gauge the exposure risk of toxicity to the public. The criteria of measuring toxicity in this review (plant compound, family, quantity, and toxicity effects) across the entire market in the United States, with special attention to those supplements whose exposure to the consumer is maximal, provides a unique contribution to the investigation of botanical supplements.

    To evaluate the quality of pharmaceutical advertisement claims and supporting references in Australian pharmacy journals that target community pharmacists. All full-page advertisements for a medicinal product, found in two Australian pharmacy journals from the year 2012 to 2015 were included. Advertisement claims and references were evaluated by claim type (unambiguous to immeasurable) and level of evidence (strong to irrelevant) in supporting references. Two hundred and ninety distinct advertisements and 598 claims were identified, with a median of 2 claims per advertisement. Twenty-seven percent of claims were unambiguous, 40% were vague, 16% were emotive/immeasurable and 17% were non-clinical or other marketing claims. Half of all claims were referenced. Although 68% of unambiguous claims were referenced, 63% of those were supported by studies that were funded directly or indirectly by pharmaceutical companies. Only 13% of claims were supported with strong or moderate independent evidence. Pharmaceutical advertisements continue to present vague and emotive claims with little independent supporting evidence. Pharmacists need to be aware of these limitations when providing patient care. Increased awareness of this issue among pharmaceutical companies, Australian pharmaceutical journal publishers, regulators and pharmacists will assist in promoting optimised healthcare outcomes for the Australian public. © 2016 Royal Pharmaceutical Society.

    We analyzed the gizzards, and grits retained in the gizzards of 41 cranes that migrated to the Izumi Plain during the winter of 2015/2016 and died there, either due to accident or disease. These included 31 Hooded Cranes (Grus monacha) and 10 White-naped Cranes (G. vipio). We determined body weight, gizzard weight, total grit weight and number per gizzard, and size, shape, and surface roundness of the grits. Average gizzard weights were 92.4 g for Hooded Cranes and 97.1 g for White-naped Cranes, and gizzard weight positively correlated with body weight in both species. Average total grit weights per gizzard were 19.7 g in Hooded Cranes and 25.7 g in White-naped Cranes, and were significantly higher in the latter. Average percentages of body weight to grit weight were 0.8% in Hooded Cranes and 0.5% in White-naped Cranes. Average grit number per gizzard was 693.5 in Hooded Cranes and 924.2 in White-naped Cranes, and were significantly higher in the latter. The average grit size was 2.8 mm in both species. No differences were found in the shape and surface roundness of grits between the two species. To the best of our knowledge, this is the first study on the grits retained in the gizzards of Hooded and White-naped Cranes.

    Full Text Available Fungi and other eukaryotes represent one of the last frontiers of microbial diversity in the sponge holobiont. In this study we employed pyrosequencing of 18S ribosomal RNA gene amplicons containing the V7 and V8 hypervariable regions to explore the fungal diversity of seven sponge species from the North Sea and the Mediterranean Sea. For most sponges, fungi were present at a low relative abundance averaging 0.75% of the 18S rRNA gene reads. In total, 44 fungal OTUs (operational taxonomic units were detected in sponges, and 28 of these OTUs were also found in seawater. Twenty-two of the sponge-associated OTUs were identified as yeasts (mainly Malasseziales, representing 84% of the fungal reads. Several OTUs were related to fungal sequences previously retrieved from other sponges, but all OTUs were also related to fungi from other biological sources, such as seawater, sediments, lakes and anaerobic digesters. Therefore our data, supported by currently available data, point in the direction of mostly accidental presence of fungi in sponges and do not support the existence of a sponge-specific fungal community.

    2017-12-01

    Full Text Available Circular to subcircular boreholes were found on the surfaces of three different bivalve shells (Mactra chinensis, Felaniella usta, and Nuttallia japonica that were pushed onto the sand beach at Sagot Cape, Baengnyeongdo, Korea. The boreholes are characterized by beveled holes that are parabolic in cross section. The boreholes are classified into the ichnospecies Oichnus paraboloides, probably drilled by a naticid gastropod Glossaulax didyma didyma living in the Baengnyeong tidal flat. In the case of Mactrashells, boreholes are observed more or less evenly on left and right valves, and 96% of boreholes are located on the umbo. This may suggest that the life position of the Baengnyeong bivalves did not dictate the preference of G. didyma didyma in the Baengnyeong tidal flat ecosystem. The clustered distribution of the boreholes in the umbo area indicates a strong site selectivity for boreholes that is quite a common phenomenon in many naticid gastropods.

    Hydrogels of chitosan were synthesised using glutaric dialdehyde as the crosslinking agent in an acetonitrile/water solution (1:4, v/v). These hydrogels recognised and adsorbed the dibenzothiophene sulfone (DBTS) against other related compounds found in diesel, e.g. dibenzothiophene (DBT), fluorene (FLE) and 4,6-dimethyl DBT (DMDBT). In order to improve the recognition and adsorption of DBTS, the latter compound served as a template for the building of recognition sites inside the hydrogel matrix through the use of the molecular imprinting technique (MIT). Despite the adsorption capacity of the molecular imprinted hydrogel (MIH) was not increased, the imprinting process of chitosan allowed both an enhancement of two orders of magnitude in ligand affinity constant and material homogeneity as seen by SEM. The change in swelling degree (Q) suggested the presence of a conformational memory of the hydrogel that might allow the design of stimuli-response but also tailored-made hydrogels responding at a required factor as temperature. The imprinting process improved ligand recognition and consequently hydrogel's specificity as shown by a monolayer adsorption. In contrast, the adsorption isotherm of DBTS by the non-imprinted hydrogel showed a multilayer adsorption due to non-specific interactions. (author)

    Full Text Available The objectives of this study were to characterize peptides found in unprocessed amaranth hydrolysates (UAH and extruded amaranth hydrolysates (EAH and to determine the effect of the hydrolysis time on the profile of peptides produced. Amaranth grain was extruded in a single screw extruder at 125 °C of extrusion temperature and 130 rpm of screw speed. Unprocessed and extruded amaranth flour were hydrolyzed with pepsin/pancreatin enzymes following a kinetic at 10, 25, 60, 90, 120 and 180 min for each enzyme. After 180 min of pepsin hydrolysis, aliquots were taken at each time during pancreatin hydrolysis to characterize the hydrolysates by MALDI-TOF/MS-MS. Molecular masses (MM (527, 567, 802, 984, 1295, 1545, 2034 and 2064 Da of peptides appeared consistently during hydrolysis, showing high intensity at 10 min (2064 Da, 120 min (802 Da and 180 min (567 Da in UAH. EAH showed high intensity at 10 min (2034 Da and 120 min (984, 1295 and 1545 Da. Extrusion produced more peptides with MM lower than 1000 Da immediately after 10 min of hydrolysis. Hydrolysis time impacted on the peptide profile, as longer the time lower the MM in both amaranth hydrolysates. Sequences obtained were analyzed for their biological activity at BIOPEP, showing important inhibitory activities related to chronic diseases. These peptides could be used as a food ingredient/supplement in a healthy diet to prevent the risk to develop chronic diseases.

    2018-04-01

    Full Text Available There is an increased consumer interest in minimally processed vegetables that has led to the development of products, such as pre-cut sliced mushrooms. Few data are available on the hygienic condition and the presence of foodborne pathogens in such products. Therefore, the current study aimed to evaluate the safety and hygienic characteristics of both ready-to-eat and ready-to-cook, pre-cut sliced mushrooms obtained from a local Italian market. For the evaluation of the hygienic condition, the aerobic mesophilic bacteria, aerobic psychrotrophic bacteria and Escherichia coli enumerations were performed. Salmonella spp., Listeria monocytogenes and Campylobacter spp. were considered in the assessment of the foodborne pathogens. High microbial loads were detected, including counts higher than 5 log CFU/g for E. coli and 6 log CFU/g for the other bacteria counts considered, but no pathogens were found. Ready-to-eat and ready-to-cook products differed only for aerobic mesophilic counts (7.87 and 8.26 log CFU/g, respectively, P=0.003. Strategies to enhance the hygienic level of the mushrooms, particularly the ready-to-eat products, are needed.

    Two Steinernema isolates found in Louisiana and Mississippi were later identified as isolates of S. rarum. DNA sequences of ITS regions of the United States isolates are identical with sequences of Argentinean S. rarum strains Samiento and Noetinger and differ by two bases from the Arroyo Cabral isolate from Córdoba, Argentina. SEM observations revealed several new structures in the isolates from the US: female face views have a hexagonal-star perioral disc and eye-shaped lips; some females do not have cephalic papillae; lateral fields of infective juveniles are variable; there are two openings observed close to the posterior edge of the cloaca. Virulence of the US isolates to Anthonomus grandis, Diaprepes abbreviatus, Solenopsis invicta, Coptotermes formosanus, Agrotis ipsilon, Spodoptera frugiperda, and Trichoplusia ni and reproductive potential were evaluated in comparison with other heterorhabditid and steinernematid nematodes. Results such as particularly high virulence to S. frugiperda indicate that the biocontrol potential of the new S. rarum strains merits further study. PMID:19259427

    Expression of wild-type protein tyrosine phosphatase (PTP) 1B may act either as a tumor suppressor by dysregulation of protein tyrosine kinases or a tumor promoter through Src dephosphorylation at Y527 in human breast cancer cells. To explore whether mutated PTP1B is involved in human carcinogenesis, we have sequenced PTP1B cDNAs from human tumors and found splice mutations in ~20% of colon and thyroid tumors. The PTP1BΔE6 mutant expressed in these two tumor types and another PTP1BΔE5 mutant expressed in colon tumor were studied in more detail. Although PTP1BΔE6 revealed no phosphatase activity compared with wild-type PTP1B and the PTP1BΔE5 mutant, its expression induced oncogenic transformation of rat fibroblasts without Src activation, indicating that it involved signaling pathways independent of Src. The transformed cells were tumourigenic in nude mice, suggesting that the PTP1BΔE6 affected other molecule(s) in the human tumors. These observations may provide a novel therapeutic target for colon and thyroid cancer.

    The electron microscopic structure of cilia from the inferior turbinate of the nose was studied in 12 adults, four with chronic sinusitis, one with allergic rhinitis, two with bronchiectasis, three with deviated nasal septum, and two normals. The changes are compared with those found in nasal cilia in 14 patients with retinitis pigmentosa. There were compound cilia in the seven cases with chronic sinusitis, allergic rhinitis, and bronchiectasis but, apart from this, the structure of the cilia was similar in all 12 cases. There were variations in the microtubular pattern in about 4% of cilia, dynein arms were not seen in 4%, and in the rest an average of 5-6 dynein arms were seen in each cilium. The orientation of the cilia was 0 to 90 degrees. In the retinitis pigmentosa patients there was a highly significant increase in cilial abnormalities. The establishment on a quantitative basis of the variations in normal structure of nasal cilila facilitated the recognition of an association between cilial abnormalities and retinitis pigmentosa and should help in the identification of associations that may exist between cilial abnormalities and other diseases.

    Based on a compilation of three estimation approaches, the total nationwide population of wild pigs in the United States numbers approximately 6.3 million animals, with that total estimate ranging from 4.4 up to 11.3 million animals. The majority of these numbers (99 percent), which were encompassed by ten states (i.e., Alabama, Arkansas, California, Florida, Georgia, Louisiana, Mississippi, Oklahoma, South Carolina and Texas), were based on defined estimation methodologies (e.g., density estimates correlated to the total potential suitable wild pig habitat statewide, statewide harvest percentages, statewide agency surveys regarding wild pig distribution and numbers). In contrast to the pre-1990 estimates, none of these more recent efforts, collectively encompassing 99 percent of the total, were based solely on anecdotal information or speculation. To that end, one can defensibly state that the wild pigs found in the United States number in the millions of animals, with the nationwide population estimated to arguably vary from about four million up to about eleven million individuals.

    Samples of tree seeds, buds, and needles collected within a winter period at ambient temperatures from -11 to -17 degrees C were analyzed for the presence of methylotrophic microflora. Thin sections of blue spruce needles were found to contain bacteria morphologically close to pink-pigmented methylobacteria. The methylobacteria that were isolated in pure cultures from samples of linden seeds and buds, pine and blue spruce needles, as well as of lilac, maple, and apple buds, were classified into the genera Methylobacterium and Paracoccus based on the data of morphological studies, enzyme assay, and DNA-DNA hybridization analysis. The methanotrophs that were isolated in pure cultures from samples of linden buds and blue spruce needles were identified into the genus Methylocystis based on the data of morphological studies, enzyme assay, DNA-DNA hybridization, and the phylogenetic analysis of the particulate methane monooxygenase gene pmoA sequences. The inference is made that aerobic methylotrophic bacteria are permanently associated with plants. At the beginning of the vegetative period in spring, the phyllosphere of coniferous and deciduous trees is colonized by the methylotrophic bacteria that have wintered inside plant tissues.

    This paper describes the isolation and molecular identification of a novel paramyxovirus found during an investigation of an outbreak of neurorespiratory disease in a collection of Australian pythons. Using Illumina® high-throughput sequencing, a 17,187 nucleotide sequence was assembled from RNA extracts from infected viper heart cells (VH2) displaying widespread cytopathic effects in the form of multinucleate giant cells. The sequence appears to contain all the coding regions of the genome, including the following predicted paramyxoviral open reading frames (ORFs): 3'--Nucleocapsid (N)--putative Phosphoprotein (P)--Matrix (M)--Fusion (F)--putative attachment protein--Polymerase (L)--5'. There is also a 540 nucleotide ORF between the N and putative P genes that may be an additional coding region. Phylogenetic analyses of the complete N, M, F and L genes support the clustering of this virus within the family Paramyxoviridae but outside both of the current subfamilies: Paramyxovirinae and Pneumovirinae. We propose to name this new virus, Sunshine virus, after the geographic origin of the first isolate--the Sunshine Coast of Queensland, Australia. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available The use of targeted cancer therapies in combination with conventional chemotherapeutic agents and/or radiation treatment has increased overall survival of cancer patients. However, longer survival is accompanied by increased incidence of comorbidities due, in part, to drug side effects and toxicities. It is well accepted that inflammation and tumorigenesis are linked. Because peroxisome proliferator-activated receptor (PPAR-γ agonists are potent mediators of anti-inflammatory responses, it was a logical extension to examine the role of PPARγ agonists in the treatment and prevention of cancer. This paper has two objectives: first to highlight the potential uses for PPARγ agonists in anticancer therapy with special emphasis on their role when used as adjuvant or combined therapy in the treatment of hematological malignancies found in the vasculature, marrow, and eyes, and second, to review the potential role PPARγ and/or its ligands may have in modulating cancer-associated angiogenesis and tumor-stromal microenvironment crosstalk in bone marrow.

    Full Text Available Using a combination of flower traps and visual observations, we surveyed three watermelon (Citrullus lanatus (Thunb. Matsum. & Nakai fields in the Lower Rio Grande Valley to determine what bees inhabit this crop in this region. No managed honey bee (Apis mellifera L. hives were in any of the fields; however, two contained managed hives of the common eastern bumble bee, Bombus impatiens (Cresson. A total of 15 species were collected or observed from all three fields combined. Of these species, only four were found to be very abundant: Agapostemon angelicus Cockerell/texanus Cresson, A. mellifera, Lasioglossum coactum (Cresson, and Melissodes thelypodii Cockerell. Apis mellifera comprised 46% of all bees collected from all three fields combined and was highly abundant in two of the three fields. In the third field, however, A. mellifera and Agapostemon angelicus/texanus were equally abundant. Surprisingly, B. impatiens comprised only 1% of the total bees surveyed in all three fields combined, despite two of the fields having several managed hives each. As B. impatiens is not native to this region, it was not surprising that none were collected or observed in the field with no managed hives.

  20. ADAMTS-1 Is Found in the Nuclei of Normal and Tumoral Breast Cells.

    Suély V Silva

    Full Text Available Proteins secreted in the extracellular matrix microenvironment (ECM by tumor cells are involved in cell adhesion, motility, intercellular communication and invasion. The tumor microenvironment is expansively modified and remodeled by proteases, resulting in important changes in both cell-cell and cell-ECM interactions and in the generation of new signals from the cell surface. Metalloproteinases belonging to the ADAMTS (a disintegrin and metalloprotease with thrombospondin motifs family have been implicated in tissue remodeling events observed in cancer development, growth and progression. Here we investigated the subcellular localization of ADAMTS-1 in normal-like (MCF10-A and tumoral (MCF7 and MDA-MB-231 human breast cells. ADAMTS-1 is a secreted protease found in the extracellular matrix. However, in this study we show for the first time that ADAMTS-1 is also present in the nuclei and nucleoli of the three mammary cell lines studied here. Our findings indicate that ADAMTS-1 has proteolytic functions in the nucleus through its interaction with aggrecan substrate.

    Background: Although prescriptions are dispensed at discretion of medical professionals, many pharmaceutical companies use direct-to-consumer (DTC) advertising to increase sales. Over-the-counter (OTC) medications are similarly marketed. Methods: We examined the content of advertisements in 38 issues of 9 popular US women’s fashion magazines. We evaluated target audience, health condition, product availability, message appeal, target to females, and mention of potential side effects and benefits. Results: Sixty total medication advertisements were identified, 58.3% (95% CI: 45.8, 70.8) for prescription products. In magazines targeted to non-Hispanic Whites, >65% of advertisements were for OTC medications whereas 80% (95% CI: 66.7, 94.5) of advertisements found in Black/Latina magazines were for prescription medications. The rational appeal was used most commonly in non-Hispanic White magazines (75.9%; 95% CI: 60.3, 91.5). Emotional appeal was featured more often in prescription advertisements magazines (60.0; 95% CI:43.8, 76.2) compared to OTC (8.0; 95% CI: -2.6, 18.6). Conclusion: Although emotional appeal may be effective for selling medication to women, it often does not completely inform consumers of potential risks. PMID:28058239

    During July to November, 2006, an important archaeological excavation was conducted in Yun country, Hubei province, southern China. Chinese archaeologists found some remnant of leather materials, covered with red pigments, on a 6th century B.C. Chinese bronze sword. To understand the technology/ies that may have been utilized for manufacturing the leathers, a combined of Raman spectroscopy, FT-IR and XRF was thus applied to the remnant of leather materials. Raman analyses showed that red pigment on the leather was cinnabar (HgS). FT-IR and XRF analyses indicated that the content of some elements, such as Ca (existing as CaCO 3) and Fe (existing as Fe 2O 3), were much higher than those in the surrounding grave soil. The results inferred an application of lime depilation and retting, and the Fe-Al compound salt as tanning agent. And it was furthermore implicated that the Fe-Al salt tanning technique had been developed in the middle and late Spring and Autumn Period of China.

  3. ASSESSMENT OF RADIOACTIVE AND NON-RADIOACTIVE CONTAMINANTS FOUND IN LOW LEVEL RADIOACTIVE WASTE STREAMS

    This paper describes and presents the findings from two studies undertaken for the European Commission to assess the long-term impact upon the environment and human health of non-radioactive contaminants found in various low level radioactive waste streams. The initial study investigated the application of safety assessment approaches developed for radioactive contaminants to the assessment of nonradioactive contaminants in low level radioactive waste. It demonstrated how disposal limits could be derived for a range of non-radioactive contaminants and generic disposal facilities. The follow-up study used the same approach but undertook more detailed, disposal system specific calculations, assessing the impacts of both the non-radioactive and radioactive contaminants. The calculations undertaken indicated that it is prudent to consider non-radioactive, as well as radioactive contaminants, when assessing the impacts of low level radioactive waste disposal. For some waste streams with relatively low concentrations of radionuclides, the potential post-closure disposal impacts from non-radioactive contaminants can be comparable with the potential radiological impacts. For such waste streams there is therefore an added incentive to explore options for recycling the materials involved wherever possible

    The importance of assigning a correct provenience of ancient marble artifacts in detecting forgeries and in associating broken or separated fragments is obvious. The first use of isotopic analysis for marble provenience studies was that of Craig and Craig in 1972. The stable isotopic signature technique uses the deviation ratios for 13 C / 12 C and 18 O / 16 O relative to a conventional standard. This deviation is expressed as δ 13 C and δ 18 O. By statistical treatment of the data from the data base of some classical Greek and Roman marble quarries it could be possible to locate and to fix the extension of every quarry distribution point (δ 13 C, δ 18 O) as a scatter plot of these values. The quarry statistical characteristics could be described by a bivariate Gaussian distribution. Some marble artifacts found at Histria and Tomis sites were analyzed to determine their provenience using stable isotopic analysis and petrography. The main petrographic features are accessory mineral content, grain size, structures and texture. Comparison between the isotopic values of the samples and the ancient quarry data base was carried out by statistical methods. This allowed to find for every sample the confidence level of the provenience of any quarry of the data base, or the probability that any random point ( 13 C/ 12 C, 18 O/ 16 O) of a specific quarry falls to a distance greater than that of the measured sample point.

    The name Moellerella wisconsensis is proposed for a group of the family Enterobacteriaceae previously called enteric group 46. The species name, wisconsensis, was coined because six of the nine strains were isolated in Wisconsin. M. wisconsensis strains were negative for indole production, Voges-Proskauer, H2S production, urea, phenylalanine deaminase, lysine and ornithine decarboxylases, arginine dihydrolase, gas production from D-glucose, acid production from trehalose, and motility; the strains were positive for methyl red, citrate (Simmons), and acid production from lactose and raffinose and resistant to colistin. DNAs from five strains of M. wisconsensis were highly related (80 to 93% in reactions assayed on hydroxyapatite at 60 degrees C and 78 to 97% at 75 degrees C) to 32P-labeled DNA of the proposed type strain (CDC 2896-78, ATCC 35017). Labeled DNA from this type strain was only 2 to 32% related (at 60 degrees C) to DNA from 49 strains of named and unnamed species of Enterobacteriaceae. Eight of nine M. wisconsensis strains were isolated from human stool samples. Clinical information on one strain was available, and it was found to be associated with a case of diarrhea. On MacConkey agar, colonies of M. wisconsensis were bright red with precipitated bile around them and thus were indistinguishable from Escherichia coli colonies. Future studies should focus on the isolation of this new organism and its relationship to human disease.

    Full Text Available Being part of the Indian subcontinent both the North Eastern region of India and the Bangladesh share a long common cultural, economic and political history. One of the most critical problems of developing countries like India as well as Bangladesh is their enormous increase in human population. Contraceptive Prevalence Rate (CPR of India is 48.3 and that of Bangladesh is 53.8. As the large majority of population of both the countries belong to rural area, the family planning programmes have largely remained unsuccessful because of many factors including lack of availability of contraceptive drugs in rural markets, lack of accessibility of rural people to medical personnel as well as the lack of acceptability of synthetic drugs due to various socio-cultural and religious perceptions prevailing among many ethnic communities. These contributed to a growing interest among researchers in developing contraceptives of natural origin and at present natural herbal contraception have become one of the major focuses of modern contraceptive research. Since time immemorial herbal drugs are being practiced by various rural communities and ethnic tribes in North East India as well as in Bangladesh, and hence the acceptability of herbal contraceptives is expected to be much higher among rural folk. In different parts of North East India and Bangladesh, ethnic communities are using plant based medicinal products till today. This study aims at highlighting the contraceptive property of some plants found in North-Eastern India as well as in Bangladesh.

    The authors present the history of the founding of the French journal L'Annee Psychologique. The names of Theodule Ribot (1839-1916), Henry Beaunis (1830-1921), and Alfred Binet (1857-1911) are closely associated with the journal. Ribot's election to the chair of Experimental and Comparative Psychology at the College de France in 1888 marked the official emancipation of psychology in France. Because there was no laboratory associated with the chair, Beaunis, a physiological psychologist from Nancy, proposed to Ribot the creation of the first French laboratory of experimental psychology (1889). Under Beaunis's direction, this laboratory was established at the Sorbonne in Paris but was in fact dependent on another educational institution, L'Ecole Pratique des Hautes Etudes. In 1893 the laboratory's research was first published in a yearly journal named Travaux du Laboratoire de Psychologie Physiologique (2 volumes: 1893-1894). Binet, who joined the laboratory in 1891, was not satisfied by the form of this publication. With Beaunis's agreement, he then created L'Annee Psychologique in 1894 to develop the reputation of the laboratory's research. The authors present the evolution and vicissitudes of the journal from 1895 to 1912, with a glance up to the present.

    2005-01-01

    Fifty-eight garments were taped and searched for mid to dark blue wool fibres. These were then removed from the tapings, mounted on slides and examined using a high-power microscope (400x). A total of 2,740 blue wool fibres were identified and visible range microspectrophotometry (MSP) was performed on them. Three hundred independent blue wool populations were identified on 56 of the 58 garments searched. The lack of control fibres meant the spectral range of each population was unknown. The number of populations may have been underestimated by grouping together the fibres that had broad single peaks and a lack of distinguishing features in the spectra. Although blue wool is considered to be a common fibre type, 300 unique spectral shapes were identified by the use of microspectrophotometry alone. This demonstrates that the dyes used in the dyeing of blue wool are variable. Showing that many different populations of blue wool occur on a range of garments should ensure that the forensic scientist does not underestimate or understate the strength of evidence in cases where blue wool is found. Hopefully this work will enlighten scientists and enable them to also assess the true value of their findings when other commonly occurring fibres are encountered.

    Full Text Available A total of 102 honey samples collected from small apiaries (≤ 20 hives in Poland were analysed for the presence of Clostridium botulinum spores. The samples were prepared using the dilution centrifugation method and cultured in parallel in cooked meat medium (CMM and tripticase peptone glucose yeast (TPGY enrichment broths. Identification of toxin types A, B, and E of Clostridium botulinum strains was performed with the use of the multiplex PCR method. Positive samples were also subjected to quantitative analysis with the use of Clostridium botulinum Isolation Agar Base (CBAB. The prevalence analysis showed 22 (21.6% samples contaminated with C. botulinum spores. The major serotype detected was botulin neurotoxin type A – 16 (72.7% whereas type B was found in 3 (13.6% honey samples and type E also only in 3 (13.6% honey samples. Dual-toxin-producing strains were noted. The average quantity of spores in PCR - C. botulinum positive samples was 190 in 1 gram of honey.

The aim of this review is to discuss in greater detail the topics covered in the recent symposium entitled “Traumatic brain injury: laboratory and clinical perspectives,” presented at the 2014 International Behavioral Neuroscience Society annual meeting. Herein we review contemporary laboratory models of traumatic brain injury (TBI) including common assays for sensorimotor and cognitive behavior. New modalities to evaluate social behavior after injury to the developing brain, as well as the attentional set-shifting test (AST) as a measure of executive function in TBI, will be highlighted. Environmental enrichment (EE) will be discussed as a preclinical model of neurorehabilitation, and finally, an evidence-based approach to sports-related concussion will be considered. The review consists predominantly of published data, but some discussion of ongoing or future directions is provided. PMID:25496906

  11. From Founding Father to Pious Son: Filiation, Language, and Royal Inheritance in Alfonso X, the Learned

    Ryan Szpiech

    2015-07-01

    Full Text Available The influence of King Alfonso X of Castile (reg. 1252–1284 has been so wide that modern historians have stressed Alfonso’s foundational role as a ‘father’ of many Castilian cultural institutions and areas of writing, including prose literature, science, the legal code, and vernacular historiography. This paper argues that the modern focus on Alfonso’s foundational, ‘fatherly’ role, while logical in the context of modern literary historiography, is at odds with Alfonso’s own medieval view of himself as a ‘son’ and heir, one who inherited rather than founded cultural institutions. It proposes that a reorientation of Alfonsine studies according to this medieval worldview, one focused less on Alfonso’s innovations and foundations and more on his continuty with and dependance on his forebears, will permit a clearer portrayal of Alfonso’s importance in medieval literary history. To this end, it explores Aflonso’s representation of himself as the ‘son’ of his father, King Fernando III, in the prologues to his scientific translations, in his encomium of his father known as the Setenario, and in song 292 of his Cantigas de Santa María. A reading of these examples is offered as a first step towards the study of filiation and ‘sonship’ in the vast Alfonsine historiographical and legal corpuses.

    Drinking water for Riga city is provided by the groundwater well field complex “Baltezers, Zakumuiza, Rembergi” and by the Daugava river as a surface water source. Presently (2016), the both sources jointly supply 122 thous.metre3day-1 of drinking water. It seems reasonable to use in future only groundwater, because river water is of low quality and its treatment is expensive. The research on this possibility was done by scientists of Riga Technical university as the task drawn up by the company “Aqua-Brambis”. It was required to evaluate several scenario of the groundwater supply for Riga city. By means of hydrogeological modelling, it was found out that groundwater well fields could provide 120-122 thous.metre3day-1 of drinking water for the Riga city and it is possible further not to use water of the Daugava river. However, in order to provide more extensive use of groundwater sources, existing water distribution network shall be adapted to the change of the water sources and supply directions within the network. Safety of water supply shall be ensured. The publication may be of interest for specialists dealing with problems of water supply for large towns.

    DNA polymerase (pol) η is a specialized error-prone polymerase with at least two quite different and contrasting cellular roles: to mitigate the genetic consequences of solar UV irradiation, and promote somatic hypermutation in the variable regions of immunoglobulin genes. Misregulation and mistargeting of pol η can compromise genome integrity. We explored whether the mutational signature of pol η could be found in datasets of human somatic mutations derived from normal and cancer cells. A substantial excess of single and tandem somatic mutations within known pol η mutable motifs was noted in skin cancer as well as in many other types of human cancer, suggesting that somatic mutations in A:T bases generated by DNA polymerase η are a common feature of tumorigenesis. Another peculiarity of pol ηmutational signatures, mutations in YCG motifs, led us to speculate that error-prone DNA synthesis opposite methylated CpG dinucleotides by misregulated pol η in tumors might constitute an additional mechanism of cytosine demethylation in this hypermutable dinucleotide.

    This study aims to show that health websites not asking for HONcode certification (Control sample websites A) do not respect elementary ethical standards such as the HONcode. The HONcode quality and ethical standards and the certification process have been developed by the Health on the Net Foundation to improve the transparency of the health and medical information found on the Internet. We compared the compliance with the 8 HONcode principles, and respectively the respect of principles 1 (authority), 4 (assignment), 5 (justification) and 8 (honesty in advertising and editorial policy) by certified websites (A) and by health websites which have not requested the certification (B). The assessment of the HONcode compliance was performed by HON evaluators by the same standards for all type of sites. Results shows that 0.6% of health websites not asking for HONcode certification does respect the eight HONcode ethical standards vs. 89% of certified websites. Regarding the principles 1, 4, 5 and 8, 1.2% of B respect these principles vs. 92% for A. The certification process led health websites to respect the ethical and quality standards such as the HONcode, and disclosing the production process of the health website.

    Mutations within LRRK2, most notably p.G2019S, cause Parkinson’s disease (PD) in rare monogenic families, and sporadic occurrences in diverse populations. We investigated variation throughout LRRK2 (84 SNPs; genotype or diplotype found for 49 LD blocks) for 275 cases (European ancestry, onset at age 60 or older) and 275 neurologically healthy control subjects (NINDS Neurogenetics Repository). Three grade-of-membership groups, i.e. genetic risk sets, were identified that exactly matched many subjects (cases: 46, 4, 137; controls: 0, 178, 0), and distinguished 94% of the subjects (i.e. > 50% likeness to one set). Set I, affected, carried certain low frequency alleles located in multiple functional domains. Set II was unaffected. Set III, also affected, resembled II except for slightly elevated frequencies of minor alleles not defining set I. We conclude that certain low frequency alleles distributed throughout LRRK2 are a genetic background to a third of cases, defining a distinct subset. PMID:19489756

    There is an increased consumer interest in minimally processed vegetables that has led to the development of products, such as pre-cut sliced mushrooms. Few data are available on the hygienic condition and the presence of foodborne pathogens in such products. Therefore, the current study aimed to evaluate the safety and hygienic characteristics of both ready-to-eat and ready-to-cook, pre-cut sliced mushrooms obtained from a local Italian market. For the evaluation of the hygienic condition, the aerobic mesophilic bacteria, aerobic psychrotrophic bacteria and Escherichia coli enumerations were performed. Salmonella spp., Listeria monocytogenes and Campylobacter spp. were considered in the assessment of the foodborne pathogens. High microbial loads were detected, including counts higher than 5 log CFU/g for E. coli and 6 log CFU/g for the other bacteria counts considered, but no pathogens were found. Ready-to-eat and ready-to-cook products differed only for aerobic mesophilic counts (7.87 and 8.26 log CFU/g, respectively, P=0.003). Strategies to enhance the hygienic level of the mushrooms, particularly the ready-to-eat products, are needed.

    We introduce PROFOUND, a source finding and image analysis package. PROFOUND provides methods to detect sources in noisy images, generate segmentation maps identifying the pixels belonging to each source, and measure statistics like flux, size, and ellipticity. These inputs are key requirements of PROFIT, our recently released galaxy profiling package, where the design aim is that these two software packages will be used in unison to semi-automatically profile large samples of galaxies. The key novel feature introduced in PROFOUND is that all photometry is executed on dilated segmentation maps that fully contain the identifiable flux, rather than using more traditional circular or ellipse-based photometry. Also, to be less sensitive to pathological segmentation issues, the de-blending is made across saddle points in flux. We apply PROFOUND in a number of simulated and real-world cases, and demonstrate that it behaves reasonably given its stated design goals. In particular, it offers good initial parameter estimation for PROFIT, and also segmentation maps that follow the sometimes complex geometry of resolved sources, whilst capturing nearly all of the flux. A number of bulge-disc decomposition projects are already making use of the PROFOUND and PROFIT pipeline, and adoption is being encouraged by publicly releasing the software for the open source R data analysis platform under an LGPL-3 license on GitHub (github.com/asgr/ProFound).

    To better understand the roles of leaves at different stem positions during plant development, we measured the physiological properties of leaves 1-4 on maize seedling stems, and performed a proteomics study to investigate the differences in protein expression in the four leaves using two-dimensional difference gel electrophoresis and tandem mass spectrometry in conjunction with database searching. A total of 167 significantly differentially expressed protein spots were found and identified. Of these, 35% are involved in photosynthesis. By further analysis of the data, we speculated that in leaf 1 the seedling has started to transition from a heterotroph to an autotroph, development of leaf 2 is the time at which the seedling fully transitions from a heterotroph to an autotroph, and leaf maturity was reached only with fully expanded leaves 3 and 4, although there were still some protein expression differences in the two leaves. These results suggest that the different leaves make different contributions to maize seedling growth via modulation of the expression of the photosynthetic proteins. Together, these results provide insight into the roles of the different maize leaves as the plant develops from a heterotroph to an autotroph. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Between 2007 and 2014, 83 cetaceans were found stranded along the Ligurian coast of Italy, in the Pelagos Sanctuary, the largest marine protected area in the Mediterranean basin. Forty-nine (59%) were submitted to complete or partial necropsy, depending on the conservation status of the carcass. Based on gross and histological pathology and ancillary testing, the cause of death was determined and categorized as anthropogenic or natural (i.e., nonanthropogenic) in origin for 33 animals (67%) and of undetermined origin in the remaining 16 (33%). Natural causes of death, accompanied by either poor or good nutritional status, were attributed to 29 animals (59%), whereas four (8%) were diagnosed with an anthropogenic cause of death, consisting of interaction with fishing activities. Infectious and noninfectious disease was the most common cause of death, involving 29 cetaceans (59%). These data are valuable for understanding health and mortality trends in cetacean populations and can provide information for establishing policies for cetacean conservation and management in such an important protected area of the Mediterranean basin.

    This paper presents an ontologically founded basic architecture for information systems, which are intended to capture, represent, and maintain metadata for various domains of clinical and epidemiological research. Clinical trials exhibit an important basis for clinical research, and the accurate specification of metadata and their documentation and application in clinical and epidemiological study projects represents a significant expense in the project preparation and has a relevant impact on the value and quality of these studies.An ontological foundation of an information system provides a semantic framework for the precise specification of those entities which are presented in this system. This semantic framework should be grounded, according to our approach, on a suitable top-level ontology. Such an ontological foundation leads to a deeper understanding of the entities of the domain under consideration, and provides a common unifying semantic basis, which supports the integration of data and the interoperability between different information systems.The intended information systems will be applied to the field of clinical and epidemiological research and will provide, depending on the application context, a variety of functionalities. In the present paper, we focus on a basic architecture which might be common to all such information systems. The research, set forth in this paper, is included in a broader framework of clinical research and continues the work of the IMISE on these topics.

    We report the distribution of mosquitoes of the maculipennis complex in two distinct areas of the Czech Republic (Bohemia and South Moravia) and in one locality of neighbouring Slovakia with emphasis on the detection of the newly described cryptic species Anopheles daciae (Linton, Nicolescu & Harbach, 2004). A total of 691 mosquitoes were analysed using a species-specific multiplex PCR assay to differentiate between the members of the maculipennis complex. In the Czech Republic, we found Anopheles maculipennis (with a prevalence rate of 1.4%), Anopheles messeae (49.0%) and Anopheles daciae (49.6%). In Slovakia, only An. messeae (52.1%) and An. daciae (47.9%) were detected. In this study, An. daciae was documented for the first time in the two countries where it represented a markedly higher proportion of maculipennis complex species (with an overall prevalence almost reaching 50%) in comparison to previous reports from Germany, Romania and Poland. The determination of the differential distribution of maculipennis complex species will contribute to assessing risks of mosquito-borne diseases such as malaria or dirofilariasis.

    To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome. Prospective case series study. 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress. Brachycephalic dogs anesthetized for pharyngoscopy and laryngoscopy between January 2007 and June 2008 underwent flexible bronchoscopy for systematic evaluation of the principal and lobar bronchi. For dogs that underwent surgical correction of any component of brachycephalic syndrome, owners rated surgical outcome during a follow-up telephone survey. Correlation between laryngeal collapse and bronchial abnormalities and association between bronchial abnormalities and long-term outcome were assessed. Pugs (n = 20), English Bulldogs (13), and French Bulldogs (7) were affected. A fixed bronchial collapse was recognized in 35 of 40 dogs with a total of 94 bronchial stenoses. Abnormalities were irregularly distributed between hemithoraces; 15 of 94 bronchial abnormalities were detected in the right bronchial system, and 79 of 94 were detected in the left. The left cranial bronchus was the most commonly affected structure, and Pugs were the most severely affected breed. Laryngeal collapse was significantly correlated with severe bronchial collapse; no significant correlation was found between severity of bronchial abnormalities and postsurgical outcome. Bronchial collapse was a common finding in brachycephalic dogs, and long-term postsurgical outcome was not affected by bronchial stenosis.

  5. Principles of methodology guiding the study of religion as found in the work of Friedrich Heiler

    Full Text Available The issue of methodology in the study of religious phenomena appears as problematic to those Russian experts who deal with the scientific study of religious phenomena. On the other hand, western European researchers have already made much positive progress in this direction. This article attempts to define the principles which guide the scholar in the study of religion as found in the work of the renowned German scholar Friedrich Heiler. The author’s starting point is Heiler’s fundamental concept which permeates all his work and is most clearly defined in his last monograph: «Erscheinungsformen und Wesen der Religion». Heiler gives several pointers to students of religion: attention to detail, a fi rm grounding in the core matter of the object to be studies, and at the same time a comprehensive and panoramic view of religion and religious phenomena as a whole. The author concludes that Heiler’s protracted study of both Christianity and the Eastern religions led him to regard the phenomenological method as the most eff ective. The author presupposes a negative reception of this method by Russian students of religious phenomena due to the fact that the latter are too unfamiliar with Heiler’s work and conclusions

    As in other cold seeps, the dominant bivalves in mud volcanoes (MV) from the Gulf of Cadiz are macrofauna belonging to the families Solemyidae (Acharax sp., Petrasma sp.), Lucinidae (Lucinoma sp.), Thyasiridae (Thyasira vulcolutre) and Mytilidae (Bathymodiolus mauritanicus). The delta(13)C values measured in solemyid, lucinid and thyasirid specimens support the hypothesis of thiotrophic nutrition, whereas isotopic signatures of B. mauritanicus suggest methanotrophic nutrition. The indication by stable isotope analysis that chemosynthetic bacteria make a substantial contribution to the nutrition of the bivalves led us to investigate their associated bacteria and their phylogenetic relationships based on comparative 16S rRNA gene sequence analysis. PCR-denaturing gradient gel electrophoresis analysis and cloning of bacterial 16S rRNA-encoding genes confirmed the presence of sulfide-oxidizing symbionts within gill tissues of many of the studied specimens. Phylogenetic analysis of bacterial 16S rRNA gene sequences demonstrated that most bacteria were related to known sulfide-oxidizing endosymbionts found in other deep-sea chemosynthetic environments, with the co-occurrence of methane-oxidizing symbionts in Bathymodiolus specimens. This study confirms the presence of several chemosynthetic bivalves in the Gulf of Cadiz and further highlights the importance of sulfide- and methane-oxidizing symbionts in the trophic ecology of macrobenthic communities in MV.

    Full Text Available Calliphorid larvae are important in the decomposition of carrion. Since these larvae are present in the primary stages of succession on carcasses, they may be important indicators of death time and the movement of corpses in homicide investigations. In this study we examined the morphological differences among puparia of Chrysomya megacephala, C. putoria and Cochliomyia macellaria. Puparia of the three species (N=30, each were obtained from the F2 generation bred in culture medium at 25° C, and 60% relative humidity on a 12 h photoperiod. The interspecific differences found were related to the conspicuousness of six tubercles located in the region near the posterior spiracles and to the distance between the two peritrema involving the spiracles. The latter were (mean ± SD 15.2 ± 3.1 mum for C. megacephala, 18.8 ± 2.8 mum for C. putoria and 16.5 ± 3.5 mum for C. macellaria. The results of the present study may be useful in forensic entomology.

    Hot Jupiter systems provide unique observational constraints for migration models in multiple systems and binaries. We report on the discovery of the Kepler-424 (KOI-214) two-planet system, which consists of a transiting hot Jupiter (Kepler-424b) in a 3.31 day orbit accompanied by a more massive outer companion in an eccentric (e = 0.3) 223 day orbit. The outer giant planet, Kepler-424c, is not detected transiting the host star. The masses of both planets and the orbital parameters for the second planet were determined using precise radial velocity (RV) measurements from the Hobby-Eberly Telescope (HET) and its High Resolution Spectrograph (HRS). In stark contrast to smaller planets, hot Jupiters are predominantly found to be lacking any nearby additional planets; they appear to be l onely . This might be a consequence of these systems having a highly dynamical past. The Kepler-424 planetary system has a hot Jupiter in a multiple system, similar to υ Andromedae. We also present our results for Kepler-422 (KOI-22), Kepler-77 (KOI-127), Kepler-43 (KOI-135), and Kepler-423 (KOI-183). These results are based on spectroscopic data collected with the Nordic Optical Telescope (NOT), the Keck 1 telescope, and HET. For all systems, we rule out false positives based on various follow-up observations, confirming the planetary nature of these companions. We performed a comparison with planetary evolutionary models which indicate that these five hot Jupiters have heavy element contents between 20 and 120 M ⊕ .

    In the 1970s, during excavations at Los Morrillos, San Juan, Argentina, quinoa seeds were found within ancient pumpkin crocks protected from the light and high temperatures, and preserved in the very dry conditions of the region. The radiocarbon dates confirmed the age of these seeds at around 2300 years. Sectioning of some of these seeds showed reddish-brown embryos, different from the white embryos of recently harvested quinoa seeds. The ancient seeds did not germinate. The structure of the embryo cells was examined using light and transmission electron microscopy; proteins were analyzed by electrophoresis followed by Coomassie blue and periodic acid Schiff staining and fatty acids by gas chromatography. The state of nuclear DNA was investigated by TUNEL assay, DAPI staining, ladder agarose electrophoresis and flow cytometry. Results suggest that, although the embryo tissues contained very low water content, death occurred by a cell death program in which heterochromatin density was dramatically reduced, total DNA was degraded into small fragments of less than 500bp, and some proteins were modified by non-enzymatic glycation, generating Maillard products. Polyunsaturated fatty acids decreased and became fragmented, which could be attributable to the extensive oxidation of the most sensitive species (linolenic and linoleic acids) and associated with a collapse of lipid bodies.

    Genomes usually contain some non-repetitive sequences that are missing from the reference genome and occur only in a population subset. Such non-repetitive, non-reference (NRNR) sequences have remained largely unexplored in terms of their characterization and downstream analyses. Here we describe 3,791 breakpoint-resolved NRNR sequence variants called using PopIns from whole-genome sequence data of 15,219 Icelanders. We found that over 95% of the 244 NRNR sequences that are 200 bp or longer are present in chimpanzees, indicating that they are ancestral. Furthermore, 149 variant loci are in linkage disequilibrium (r 2 > 0.8) with a genome-wide association study (GWAS) catalog marker, suggesting disease relevance. Additionally, we report an association (P = 3.8 × 10 -8 , odds ratio (OR) = 0.92) with myocardial infarction (23,360 cases, 300,771 controls) for a 766-bp NRNR sequence variant. Our results underline the importance of including variation of all complexity levels when searching for variants that associate with disease.

    Tributyltin (TBT) and its degradation products, mono- (MBT) and dibutyltin (DBT), were determined in liver, kidney, and brain tissues of adult southern sea otters (Enhydra lutris nereis) found dead along the coast of California during 1992a??1996. Hepatic concentrations of butyltin compounds (BTs = MBT + DBT + TBT) ranged from 40 to 9200 ng/g wet wt, which varied depending on the sampling location and gender. Concentrations of BTs in sea otters were comparable to those reported in stranded bottlenose dolphins from the U.S. Atlantic Coast during 1989a??1994. Greater accumulation of butyltins in sea otters was explained by their bottom-feeding habit and the diet that consists exclusively of invertebrates such as mollusks and gastropods. Livers of female sea otters contained approximately 2-fold greater concentrations of BTs than did those of males. The composition of butyltin compounds in sea otter tissues was predominated by TBT in most cases and suggestive of recent exposure. Large harbors such as Monterey Harbor that handle ships legally painted with TBT-containing antifouling paints continued to experience ecotoxicologically significant butyltin contamination. Sea otters, which were affected by infectious diseases, contained greater concentrations of BTs in their tissues than those that died from trauma and other unknown causes.

    2014-04-01

    In a first part, the author analyses and discusses the present situation of energy in Europe, and wanders whether it will turn to be something like a chaos foretold. The author notably outlines the too slow implementation of the European gas market, wanders about the actual existence of an electricity market, and outlines the weakened credibility of the European energy policy. In a second part, the author proposes a further analysis of this crisis of the European energy and tries to identify its origins and to show that, although ambitious, this project was founded on neither an actual vision nor means. Ambiguities of the Lisbon Treaty are outlined. The behaviour of member States is described as the triumph of the 'every-man for himself' principle, and the author wanders about the ability of the Commission in the search of a balanced position. In the third part, the author proposes guidelines for a re-foundation of the European energy contract. These guidelines are: to base the European energy policy on solidarity and sustainability, to favour the use of all energy sources by introducing a political coordination between member States, and to put the Directorate General for Energy (DG Energy or ENER) at the heart of the governance of the European energy policy

    In murine models of obesity/diabetes, there is an increase in plasma serum amyloid A (SAA) levels along with redistribution of SAA from high-density lipoprotein (HDL) to apolipoprotein B (apoB)-containing lipoprotein particles, namely, low-density lipoprotein and very low-density lipoprotein. The goal of this study was to determine if obesity is associated with similar SAA lipoprotein redistribution in humans. Three groups of obese individuals were recruited from a weight loss clinic: healthy obese (n = 14), metabolic syndrome (MetS) obese (n = 8), and obese with type 2 diabetes (n = 6). Plasma was separated into lipoprotein fractions by fast protein liquid chromatography, and SAA was measured in lipid fractions using enzyme-linked immunosorbent assay and Western blotting. Only the obese diabetic group had SAA detectable in apoB-containing lipoproteins, and SAA reverted back to HDL with active weight loss. In human subjects, SAA is found in apoB-containing lipoprotein particles only in obese subjects with type 2 diabetes, but not in healthy obese or obese subjects with MetS.

    In the USA, botanical dietary supplements are presumed to be safe, but this is not necessarily always the case. Extracts of the evergreen tree yohimbe, Pausinystalia johimbe, though banned in many countries, are sold in hundreds of dietary supplements in the USA. We analyzed 49 brands of supplements labelled as containing yohimbe or yohimbine available for sale from seven major retailers in the USA. Supplements were analyzed using ultra high-performance liquid chromatography coupled to photodiode and quadrupole time-of-flight mass spectrometry detectors for quantity of three alkaloids found in P. johimbe (yohimbine, rauwolscine, and corynanthine). The alkaloids were confirmed on the basis of retention time, ultraviolet spectra, and mass spectra against reference standards. The quantity of the most active alkaloid, yohimbine, per recommended serving ranged from none detected to 12.1 mg. Thirty-nine percent of the supplements (19/49) did not contain rauwolscine and corynanthine suggesting that the yohimbine was either from highly processed plant extract or synthetic in origin. Only 11 supplement brands (22%, 11/49) listed a specific quantity of yohimbine on the label. Most of these were inaccurately labelled (actual content ranged from 23% to 147% of the content on the label). Eighteen percent (9/49) of the supplements' labels did not provide any information about yohimbine's adverse effects. Of the 49 yohimbine supplement brands sold at seven major retail chains in the USA, only 4.1% (2/49) provided consumers with both accurate information about the quantity of yohimbine as well as information about yohimbine's known adverse effects.

  17. Cytogenetic and molecular genetic analysis of leukemias found in atomic bomb survivors

    1994-01-01

    Seventy five radiation-related leukemia patients in Hiroshima including 16 patients exposed to more than one Gray were cytogenetically examined. Statistical analysis of data on the frequencies of chromosomal aberrations in the survivor groups according to bone marrow doses by DS86 estimation revealed that the heavily exposed group tended to have significantly higher aberration rates compared to the non-exposed group. Furthermore, the chromosomal aberrations in the survivors were observed to be of a more complex nature and had the characteristic findings of secondary leukemia. These observations therefore suggest that patients with a history of heavy exposure to atomic bomb radiation had leukemic cells originating from a stem cell which had been damaged by irradiation at the time of the bombing as well as cells involved in complex chromosome abnormalities. A higher incidence(p=0.06) of 11q23 abnormality was found in acute leukemia patients who had a history of exposure to A-bomb and developed from 1986 to 1993. However, we could not detect rearrangement of MLL gene in these patients. Break point region on 11q23 of radiation induced leukemias may be different from the common 8.5 kb region. Molecular biologic studies on RAS genes in acute and chronic leukemias and the BCR gene in chronic myelocytic leukemia were performed in exposed and non-exposed groups. So far, no distinctive differences have been observed in the frequency and sites of point mutations in N and K-RAS genes or in the rearrangement of the BCR gene. Further, retrospective analysis using DNA from leukemia patients who developed the disease in the early period from atomic bomb radiation exposure would be useful for elucidation of the mechanisms of radiation-induced leukemia.

    We present an analysis and interpretation of the Kepler binary system KOI 1224. This is the fourth binary found with Kepler that consists of a thermally bloated, hot white dwarf in a close orbit with a more or less normal star of spectral class A or F. As we show, KOI 1224 contains a white dwarf with T eff = 14, 700 ± 1000 K, mass = 0.22 ± 0.02 M ☉ , and radius = 0.103 ± 0.002 R ☉ , and an F-star companion of mass 1.59 ± 0.06 M ☉ that is somewhat beyond its terminal-age main sequence. The orbital period is quite short at 2.69802 days. The ingredients that are used in the analysis are the Kepler binary light curve, including the detection of the Doppler boosting effect; the NUV and FUV fluxes from the GALEX images of this object; an estimate of the spectral type of the F-star companion; and evolutionary models of the companion designed to match its effective temperature and mean density. The light curve is modeled with a new code named Icarus which we describe in detail. Its features include the full treatment of orbital phase-resolved spectroscopy, Doppler boosting, irradiation effects, and transits/eclipses, which are particularly suited to irradiated eclipsing binaries. We interpret the KOI 1224 system in terms of its likely evolutionary history. We infer that this type of system, containing a bloated hot white dwarf, is the direct descendant of an Algol-type binary. In spite of this basic understanding of the origin of KOI 1224, we discuss a number of problems associated with producing a system with an orbital period this short.

    Diabetes insipidus is a rare disorder characterized by an impairment in water balance because of the inability to concentrate urine. While central diabetes insipidus is caused by mutations in the AVP , the reason for genetically determined nephrogenic diabetes insipidus can be mutations in AQP2 or AVPR2 After release of AVP from posterior pituitary into blood stream, it binds to AVPR2, which is one of the receptors for AVP and is mainly expressed in principal cells of collecting ducts of kidney. Receptor activation increases cAMP levels in principal cells, resulting in the incorporation of AQP2 into the membrane, finally increasing water reabsorption. This pathway can be altered by mutations in AVPR2 causing nephrogenic diabetes insipidus. In this study, we functionally characterize four mutations (R68W, ΔR67-G69/G107W, V162A and T273M) in AVPR2, which were found in Turkish patients. Upon AVP stimulation, R68W, ΔR67-G69/G107W and T273M showed a significantly reduced maximum in cAMP response compared to wild-type receptor. All mutant receptor proteins were expressed at the protein level; however, R68W, ΔR67-G69/G107W and T273M were partially retained in the cellular interior. Immunofluorescence studies showed that these mutant receptors were trapped in ER and Golgi apparatus. The function of V162A was indistinguishable from the indicating other defects causing disease. The results are important for understanding the influence of mutations on receptor function and cellular trafficking. Therefore, characterization of these mutations provides useful information for further studies addressing treatment of intracellularly trapped receptors with cell-permeable antagonists to restore receptor function in patients with nephrogenic diabetes insipidus. © 2018 The authors.

    We present the analysis of the first circumbinary planet microlensing event, OGLE-2007-BLG-349. This event has a strong planetary signal that is best fit with a mass ratio of q approx. = 3.4×10(exp -4), but there is an additional signal due to an additional lens mass, either another planet or another star. We find acceptable light-curve fits with two classes of models: two-planet models (with a single host star) and circumbinary planet models. The light curve also reveals a significant microlensing parallax effect, which constrains the mass of the lens system to be M(sub L) approx. = 0.7 Stellar Mass. Hubble Space Telescope (HST) images resolve the lens and source stars from their neighbors and indicate excess flux due to the star(s) in the lens system. This is consistent with the predicted flux from the circumbinary models, where the lens mass is shared between two stars, but there is not enough flux to be consistent with the two-planet, one-star models. So, only the circumbinary models are consistent with the HST data. They indicate a planet of mass m(sub c) = 80 +/- 13 Stellar Mass, orbiting a pair of M dwarfs with masses of M(sub A) = 0.41+/- 0.07 and M(sub B) = 0.30 +/- 0.07, which makes this the lowest-mass circumbinary planet system known. The ratio of the separation between the planet and the center of mass to the separation of the two stars is approx.40, so unlike most of the circumbinary planets found by Kepler, the planet does not orbit near the stability limit.

    The present paper shows the regulatory work made through inspections concerning radiation safety and security in the area of industrial gamma radiography. An account is shown of the items which should be available in the storage facility where the equipment and radioactive sources are placed as well as in site radiography and which are required to the users of the equipment meant for this practice, in order to ensure compliance with the regulations in force. The objective of this paper is to assess the most frequent deviations to the regulatory standards found during this type of inspections, such as lack of complete and operable radiation protection equipment, lack of available elements bound to act in case of emergency, no delimitation of controlled areas, gamma radiography equipment stored in unlocked position, wear gauge unavailable, record of movements of equipment and radioactive sources not updated, anomalous monthly or annual personal dose values, among the main findings. In particular, in connection with dose reports, some cases of occupational exposed workers exceeding the annual dose limits or investigation levels are highlighted. In addition, the explanations provided by the person responsible for radiation protection of companies in regard to the possible causes or circumstances which might have given rise to such dose values, the conclusions reached and the preventive and corrective measures implemented by these companies are analysed. Finally, an assessment of the annual dose distributions of the occupational exposed workers concerned with this kind of practice in the period 2004-2007 is shown. As a conclusion, the relevance of these deviations according to degradation in safety and security performance and the role of the regulatory work as a promoter of the implementation of safety culture will be emphasized.

    Toothpastes have multi-functional configurations as oral care products. They can however constitute a pos- sible source, amongst others, of toxic metal exposure in public health. Indeed, the public health impact of personal hygiene and consumer products is largely unknown. To determine the level of toxic metals (lead, cadmium, cobalt, chromium, nickel) in toothpastes available in Nigeria, (home produced and imported), and assess the potential risk to the people. The samples of toothpastes commonly used in Nigeria were tested. Using a market basket protocol thirty five different brands of toothpaste were used. Samples were digest by addition of 10 mL mixture of conc. nitric and hydrochloric acids (HCl:HNO(3), 3:1), followed by heating to dryness. 20 mL deionized water was added, stirred and filtered. The filtrate was made up in standard volumetric flask and lead, cadmium, chromium, cobalt and nickel concentrations were determined using the atomic absorption spectrophotometry 205A. The daily intake of metals and target hazard quotient (THQ) were then calculated. Pepsodent and Flodent had the highest levels of lead at respectively 23.575 and 18.092 mg/kg while Colgate Herbal had the highest nickel of 18.535 mg/kg. The daily intake estimates of all imported toothpaste samples were below the stated upper limits (UL). All target hazard quotients were also found to be below one. Although the UL, THQ and daily intake rates were all normal, the high levels of lead in some of the tooth- pastes an important concern to public health suggesting that pre-marketing safety studies of toothpastes may be worthwhile for the regulatory authorities.

    The sudden development of vertigo or dizziness without focal neurological symptoms is generally attributable to vestibular diseases such as benign paroxysmal positional vertigo. Isolated vertigo or dizziness attack needs more attention than vestibular diseases. This retrospective study was performed to elucidate the frequency of strokes in patients with isolated vertigo or dizziness attack. We enrolled 221 patients (men, 119; women, 102; mean age, 68.4 ± 10.3 years) who were admitted to our hospital over the last 10 years because of sudden isolated vertigo or dizziness attack without other neurological symptoms except for nystagmus, deafness, or tinnitus. We investigated the clinical features, final diagnosis, neuroimaging findings, and short- or long-term outcome of these patients. One hundred eighteen patients had vertigo whereas the other 103 had dizziness. Brain computed tomography or magnetic resonance imaging revealed recent stroke lesions in 25 patients (11.3%) (ischemic, 21; hemorrhagic, 4).The lesions were generally small and localized in the cerebellum (n = 21), pons (n = 1), medulla oblongata (n = 1), or corona radiata (n = 1). Of the 25 patients, 19 (76%) had dizzy-type spells; none had neurological dysfunction at the time of discharge. In the remaining 196 patients, no stroke was detected on computed tomography or magnetic resonance imaging. Stroke was found in 11% of patients with isolated vertigo or dizziness attack. The posterior inferior cerebellar artery area was the most frequently implicated for isolated vertigo or dizziness. Copyright © 2016 National Stroke Association. Published by Elsevier Inc.

    Many marine habitats, such as the surface and tissues of marine invertebrates, including corals, harbour diverse populations of microorganisms, which are thought to play a role in the health of their hosts and influence mutualistic and competitive interactions. Investigating the presence and stability of quorum sensing (QS) in these ecosystems may shed light on the roles and control of these bacterial communities. Samples of 13 cnidarian species were screened for the presence and diversity of N-acyl-homoserine lactones (AHLs; a prevalent type of QS molecule) using thin-layer chromatography and an Agrobacterium tumefaciens NTL4 biosensor. Ten of 13 were found to harbour species-specific, conserved AHL profiles. AHLs were confirmed in Anemonia viridis using liquid chromatography tandem mass spectrometry. To assess temporal role and stability, AHLs were investigated in A. viridis from intertidal pools over 16 h. Patterns of AHLs showed conserved profiles except for two mid-chain length AHLs, which increased significantly over the day, peaking at 20:00, but had no correlation with pool chemistry. Denaturing gel electrophoresis of RT-PCR-amplified bacterial 16S rRNA showed the presence of an active bacterial community that changed in composition alongside AHL profiles and contained a number of bands that affiliate with known AHL-producing bacteria. Investigations into the quorum sensing-controlled, species-specific roles of these bacterial communities and how these regulatory circuits are influenced by the coral host and members of the bacterial community are imperative to expand our knowledge of these interactions with respect to the maintenance of coral health. © 2013 Federation of European Microbiological Societies.

    Marine debris is an identified concern for coastal areas and is known to accumulate in large quantities in the North Pacific Ocean. The proximity of the Main Hawaiian Islands to these "garbage patches" represents an ongoing concern with little understanding of debris origins or efficacy of current mitigation policies. Debris accumulation surveys were conducted monthly between October 2013 and August 2014 and daily during January 2015 at 3 beaches on Maui's coastline. Debris accumulation rates, loads, and sources varied between sites and were influenced by both environmental and anthropogenic factors. Debris accumulation was strongly influenced by the temporal scale of sampling, with daily surveys showing a significant increase in accumulation rate. Plastics were the most common debris item at each site ranging from local, land-based debris including cigarette butts, straws, and food wrappers, to foreign, ocean-based debris such as oyster spacer tubes and hagfish traps. The results of this study indicate that the passage of a tobacco free beaches bill on Maui has not significantly reduced the amount of tobacco related debris. Alternatively, a ban on plastic grocery bags has eliminated this type of debris from Maui's shorelines, with no bags found at any of the sampling sites. The wide spread origins of collected debris further suggests that mitigation strategies to reduce debris will need to take place across hundreds of local municipalities. The efficacy of marine debris policies furthermore depends on enforcement and implementation strategy, as current results suggest policy enforcement at the producer level affords more effective results than that at the consumer level. Local debris mitigation actions have nevertheless been shown to affect debris loads, and municipalities are therefore encouraged to adopt a holistic combination of policy, community-based debris removal programs, increased public awareness, and ongoing monitoring to address marine debris.

    Population structure and genetic diversity of invasions are the result of evolutionary processes such as natural selection, drift and founding events. Some invasions are also molded by specific human activities such as selection for cultivars and intentional introduction of desired phenotypes, which can lead to low genetic diversity in the resulting invasion. We investigated the population structure, diversity and origins of a species with both accidental and intentional introduction histories, as well as long-term selection as a cultivar. Dyer's woad ( Isatis tinctoria ; Brassicaceae) has been used as a dye source for at least eight centuries in Eurasia, was introduced to eastern USA in the 1600s, and is now considered invasive in the western USA. Our analyses of amplified fragment length polymorphisms (AFLPs) from 645 plants from the USA and Eurasia did not find significantly lower gene diversity ( H j ) in the invaded compared to the native range. This suggests that even though the species was under cultivation for many centuries, human selection of plants may not have had a strong influence on diversity in the invasion. We did find significantly lower genetic differentiation ( F st ) in the invasive range but our results still suggested that there are two distinct invasions in the western USA. Our data suggest that these invasions most likely originated from Switzerland, Ukraine and Germany, which correlates with initial biological control agent survey findings. Genetic information on population structure, diversity and origins assists in efforts to control invasive species, and continued combination of ecological and molecular analyses will help bring us closer to sustainable management of plant invasions.

    An event at the end of the Cretaceous Period 65.5 m.y. ago produced an impact structure 300 km in diameter designated the Chicxulub Crater, located partly on the Yucatan Peninsula and the Caribbian Sea floor. Mass extinction following that event killed 75% of Earth's living species, including dinosaurs. To this date, the killer space object has not been identified, but it was frequently conjectured to be a comet or an asteroid. The goal of our study was to search for evidence which might implicate the culprit. The Chicxulub impact caused extensive wildfires producing Ir-rich dust fallouts in worldwide localities, among which the least contaminated by land-derived sediments may be situated on deep ocean floors. Our study is based on a sample of pelagic clay from the giant piston core LL44-GPC3 taken from the Pacific Plate, north of the Hawaiian Islands (Woods Hole Oceanographic Institution). The 1-cm thick Ir-rich layer was located at a downcore depth of 1055-1056 cm below sea floor. From a 5 cubic cm sample provided by Jim Broda, we found 29 impact glass spherules and 4 silicon carbide (SiC) crystals. SiC has been reported in carbonaceous meteorites. Our findings of SiC in the K/T boundary layer seem to implicate that an asteroid having composition akin to that of carbonaceous chondrites might have been the killer projectile during the Chicxulub event. However, impact by a comet cannot be ruled out, since the mineralogy of cometary dust is as yet unknown.

    DNMT1 is recruited to substrate sites by PCNA and UHRF1 to maintain DNA methylation after replication. The cell cycle dependent recruitment of DNMT1 is mediated by the PCNA-binding domain (PBD) and the targeting sequence (TS) within the N-terminal regulatory domain. The TS domain was found to be mutated in patients suffering from hereditary sensory and autonomic neuropathies with dementia and hearing loss (HSANIE) and autosomal dominant cerebellar ataxia deafness and narcolepsy (ADCA-DN) and is associated with global hypomethylation and site specific hypermethylation. With functional complementation assays in mouse embryonic stem cells, we showed that DNMT1 mutations P496Y and Y500C identified in HSANIE patients not only impair DNMT1 heterochromatin association, but also UHRF1 interaction resulting in hypomethylation. Similar DNA methylation defects were observed when DNMT1 interacting domains in UHRF1, the UBL and the SRA domain, were deleted. With cell-based assays, we could show that HSANIE associated mutations perturb DNMT1 heterochromatin association and catalytic complex formation at methylation sites and decrease protein stability in late S and G2 phase. To investigate the neuronal phenotype of HSANIE mutations, we performed DNMT1 rescue assays and could show that cells expressing mutated DNMT1 were prone to apoptosis and failed to differentiate into neuronal lineage. Our results provide insights into the molecular basis of DNMT1 dysfunction in HSANIE patients and emphasize the importance of the TS domain in the regulation of DNA methylation in pluripotent and differentiating cells. © The Author 2017.

    Genome analysis of Mycobacterium leprae strain Kyoto-2 in this study revealed characteristic nucleotide substitutions in gene ML0411, compared to the reference genome M. leprae strain TN. The ML0411 gene of Kyoto-2 had six SNPs compared to that of TN. All SNPs in ML0411 were non-synonymous mutations that result in amino acid replacements. In addition, a seventh SNP was found 41 bp upstream of the start codon in the regulatory region. The seven SNP sites in the ML0411 region were investigated by sequencing in 36 M. leprae isolates from the Leprosy Research Center in Japan. The SNP pattern in 14 of the 36 isolates showed similarity to that of Kyoto-2. Determination of the standard SNP types within the 36 stocked isolates revealed that almost all of the Japanese strains belonged to SNP type III, with nucleotide substitutions at position 14676, 164275, and 2935685 of the M. leprae TN genome. The geographical distribution pattern of east Asian M. leprae isolates by discrimination of ML0411 SNPs was investigated and interestingly turned out to be similar to that of tandem repeat numbers of GACATC in the rpoT gene (3 copies or 4 copies), which has been established as a tool for M. leprae genotyping. All seven Korean M. leprae isolates examined in this study, as well as those derived from Honshu Island of Japan, showed 4 copies of the 6-base tandem repeat plus the ML0411 SNPs observed in M. leprae Kyoto-2. They are termed Northeast Asian (NA) strain of M. leprae. On the other hand, many of isolates derived from the Okinawa Islands of Japan and from the Philippines showed 3 copies of the 6-base tandem repeat in addition to the M. leprae TN ML0411 type of SNPs. These results demonstrate the existence of M. leprae strains in Northeast Asian region having characteristic SNP patterns. Copyright © 2013 Elsevier B.V. All rights reserved.

    The aim of this paper is to describe the difficulties encountered when implementing stereotactic radiotherapy of non-small cell lung cancer (T1-T2, N0, M0) using a voluntary breath-hold technique. From 25/03/2010 to 22/02/2011, eight patients with a non-small cell lung cancer were selected for treatment. CT images were obtained with the patient maintaining breath-hold using a spirometer. Treatment was delivered when the patient maintains this level of breath-hold. Treatment was performed with a 4 MV and 10 MV photon beams from a linear accelerator Varian 2100CS, equipped with a 120 leaves collimator. 60 Gy or 48 Gy were delivered, in four sessions, to the 80% isodose. The planning target volume (PTV) was defined by adding a 5 mm margin to the internal target volume (ITV), the ITV corresponding to the gross tumour volume (GTV) plus a 3 mm margin. CTV is considered equal to GTV. The non-understanding of the gating technique, the great number of beams and the limited breath-hold times led to the failure of some treatments. It can be explained by some patients insufficient respiratory abilities and the low dose rate of one of the beams used for treatment, thus forcing some radiation fields to be delivered in two or three times. Implementing such a technique can be limited by the patients' physical abilities and the materials used. Some solutions were found: a training phase more intense with a coaching of the breath-hold technique more precise, or the use of an abdominal compression device. (authors)

    This clinical study was conducted to compare the levels of endotoxins (lipopolysaccharides [LPSs]) found in primary and secondary endodontic infections with apical periodontitis by correlating LPS contents with clinical/radiographic findings. In addition, the presence of target gram-negative anaerobic bacteria was also investigated. Samples were taken from 15 root canals with primary infections and 15 with secondary infections by using paper points. The limulus amebocyte lysate assay was used to quantify endotoxins, and the polymerase chain reaction technique (16S rDNA) was used for bacterial investigation. Endotoxins were detected in 100% of the root canal samples collected from primary (15/15) and secondary (15/15) infections with median values of 7.49 EU/mL and 3.96 EU/mL, respectively (P asymptomatic teeth with primary infections (P 3 mm) (P < .05). Prevotella nigrescens (10/15, 4/15), Fusobacterium nucleatum (5/15, 1/15), Treponema denticola (3/15, 1/15), and Treponema socranskii (5/15, 1/15) were detected in teeth with primary and secondary infections, respectively. P. endodontalis was present only in teeth with primary infections (5/15). Teeth with primary endodontic infections had higher contents of endotoxins and a more complex gram-negative bacterial community than teeth with secondary infections. Moreover, the levels of endotoxins were related to the severity of bone destruction in periapical tissues as well as the development of clinical features in teeth with primary infections.

    Full Text Available Transient receptor potential ankyrin1 (TRPA1 and transient receptor potential vanilloid 1 (TRPV1 are members of the TRP superfamily of structurally related, nonselective cation channels and mediators of several signaling pathways. Previously, we identified methyl syringate as an hTRPA1 agonist with efficacy against gastric emptying. The aim of this study was to find hTRPA1 and/or hTRPV1 activators in Agastache rugosa (Fisch. et Meyer O. Kuntze (A.rugosa, commonly known as Korean mint to improve hTRPA1-related phenomena. An extract of the stem and leaves of A.rugosa (Labiatae selectively activated hTRPA1 and hTRPV1. We next investigated the effects of commercially available compounds found in A.rugosa (acacetin, 4-allylanisole, p-anisaldehyde, apigenin 7-glucoside, L-carveol, β-caryophyllene, trans-p-methoxycinnamaldehyde, methyl eugenol, pachypodol, and rosmarinic acid on cultured hTRPA1- and hTRPV1-expressing cells. Of the ten compounds, L-carveol, trans-p-methoxycinnamaldehyde, methyl eugenol, 4-allylanisole, and p-anisaldehyde selectively activated hTRPA1, with EC50 values of 189.1±26.8, 29.8±14.9, 160.2±21.9, 1535±315.7, and 546.5±73.0 μM, respectively. The activities of these compounds were effectively inhibited by the hTRPA1 antagonists, ruthenium red and HC-030031. Although the five active compounds showed weaker calcium responses than allyl isothiocyanate (EC50=7.2±1.4 μM, our results suggest that these compounds from the stem and leaves of A.rugosa are specific and selective agonists of hTRPA1.

    Hot Jupiter systems provide unique observational constraints for migration models in multiple systems and binaries. We report on the discovery of the Kepler-424 (KOI-214) two-planet system, which consists of a transiting hot Jupiter (Kepler-424b) in a 3.31 day orbit accompanied by a more massive outer companion in an eccentric (e = 0.3) 223 day orbit. The outer giant planet, Kepler-424c, is not detected transiting the host star. The masses of both planets and the orbital parameters for the second planet were determined using precise radial velocity (RV) measurements from the Hobby-Eberly Telescope (HET) and its High Resolution Spectrograph (HRS). In stark contrast to smaller planets, hot Jupiters are predominantly found to be lacking any nearby additional planets; they appear to be "lonely". This might be a consequence of these systems having a highly dynamical past. The Kepler-424 planetary system has a hot Jupiter in a multiple system, similar to \\upsilon Andromedae. We also present our results for Kepler-422 (KOI-22), Kepler-77 (KOI-127), Kepler-43 (KOI-135), and Kepler-423 (KOI-183). These results are based on spectroscopic data collected with the Nordic Optical Telescope (NOT), the Keck 1 telescope, and HET. For all systems, we rule out false positives based on various follow-up observations, confirming the planetary nature of these companions. We performed a comparison with planetary evolutionary models which indicate that these five hot Jupiters have heavy element contents between 20 and 120 M ⊕. Based on observations obtained with the Hobby-Eberly Telescope, which is a joint project of the University of Texas at Austin, the Pennsylvania State University, Stanford University, Ludwig-Maximilians-Universität München, and Georg-August-Universität Göttingen.

    Hot Jupiter systems provide unique observational constraints for migration models in multiple systems and binaries. We report on the discovery of the Kepler-424 (KOI-214) two-planet system, which consists of a transiting hot Jupiter (Kepler-424b) in a 3.31 day orbit accompanied by a more massive outer companion in an eccentric (e = 0.3) 223 day orbit. The outer giant planet, Kepler-424c, is not detected transiting the host star. The masses of both planets and the orbital parameters for the second planet were determined using precise radial velocity (RV) measurements from the Hobby-Eberly Telescope (HET) and its High Resolution Spectrograph (HRS). In stark contrast to smaller planets, hot Jupiters are predominantly found to be lacking any nearby additional planets; they appear to be {sup l}onely{sup .} This might be a consequence of these systems having a highly dynamical past. The Kepler-424 planetary system has a hot Jupiter in a multiple system, similar to υ Andromedae. We also present our results for Kepler-422 (KOI-22), Kepler-77 (KOI-127), Kepler-43 (KOI-135), and Kepler-423 (KOI-183). These results are based on spectroscopic data collected with the Nordic Optical Telescope (NOT), the Keck 1 telescope, and HET. For all systems, we rule out false positives based on various follow-up observations, confirming the planetary nature of these companions. We performed a comparison with planetary evolutionary models which indicate that these five hot Jupiters have heavy element contents between 20 and 120 M {sub ⊕}.

    Three extracellular dipeptidyl peptidase genes, dppB, dppE, and dppF, were unveiled by sequence analysis of the Aspergillus oryzae genome. We investigated their differential enzymatic profiles, in order to gain an understanding of the diversity of these genes. The three dipeptidyl peptidases were expressed using Aspergillus nidulans as the host. Each recombinant enzyme was purified and subsequently characterized. The enzymes displayed similar optimum pH values, but optimum temperatures, pH stabilities, and substrate specificities varied. DppB was identified as a Xaa-Prolyl dipeptidyl peptidase, while DppE scissile substrates were similar to the substrates for Aspergillus fumigatus DPPV (AfDPPV). DppF was found to be a novel enzyme that could digest both substrates for A. fumigatus DPPIV and AfDPPV. Semi-quantitative PCR revealed that the transcription of dppB in A. oryzae was induced by protein substrates and repressed by the addition of an inorganic nitrogen source, despite the presence of protein substrates. The transcription of dppE depended on its growth time, while the transcription of dppF was not affected by the type of the nitrogen source in the medium, and it started during the early stage of the fungal growth. Based on these results, we conclude that these enzymes may represent the nutrition acquisition enzymes. Additionally, DppF may be one of the sensor peptidases responsible for the detection of the protein substrates in A. oryzae environment. DppB may be involved in nitrogen assimilation control, since the transcription of dppB was repressed by NaNO3, despite the presence of protein substrates.

    This work reports the occurrence of mites predominantly predatory, phytophagous and with varied feeding habits on plants of the Atlantic Forest vegetation type of the State of Sao Paulo. The objective was to estimate the possible role of the Atlantic Forest vegetation as reservoir of these groups of mites which are also found on plants of agricultural importance. Samples were taken from 187 plant species belonging to 73 families in three vegetation types of the Atlantic Forest from February of 2001 to October of 2002. A total of 2,887 mites belonging to 163 morpho-species of 16 families were collected. Mite diversity was high, especially of predatory mites; these corresponded to 1,562 specimens of 92 morpho-species. Within this group, Phytoseiidae comprised 71% of the specimens and 62% of the morpho-species. Phytophagous mites comprised 836 specimens of 36 morpho-species. Within this group, Tenuipalpidae comprised the larger proportion of specimens (61%) whereas Tetranychidae corresponded to the larger proportion of morpho-species (64%). Mites with varied feeding habits corresponded to 491 specimens of 36 morpho-species. In this group, the larger proportion of specimens (52%) consisted of Ascidae and the larger proportion of morpho-species (42%) consisted of Tydeinae (family Tydeidae). High abundance and high morpho-species richness of mites of predominantly predatory, phytophagous and variable feeding habits were observed on 17, five and nine plant species, respectively. The results obtained suggest the importance of plants of the studied vegetation as reservoirs of predatory mites. (author)

    Plastic is becoming increasingly more abundant in the marine environment. Plastic ingestion has been shown to be a source of exposure to a variety of harmful compounds, such as polycyclic aromatic hydrocarbons (PAHs), bisphenol A (BPA), and phthalates, which are known for their negative physiological effects on the endocrine system as well as their ability to adsorb and leach from plastic into the bodies of marine organisms. The physiological effects of these compounds on loggerhead sea turtles (Caretta caretta) still remain unknown. This study investigated the presence of toxicants on marine plastic samples collected from Bermuda, the Sargasso Sea, and the North Atlantic Ocean. Gas chromatography/triple quadruple mass spectrometry (GC/MS) analysis showed PAHs were present on many plastic debris samples. Plastic additives such as phthalates and (BPA) were also found. ΣPAH concentrations for anthracene, chrysene, benzo[b]fluoranthene, and benzo[k]fluoranthene for 2013 environmental plastic samples averaged 26.7ng/g of plastic. This study also examined the presence of these compounds in fluids from the stomach, small intestine, and large intestine from two adult loggerhead turtles. GC/MS analysis also showed the presence of BPA and phthalates on plastic samples, as well as in two out of the six gastrointestinal fluids samples. Average ΣPAH concentration for GI fluids for the loggerheads in the study was 58.7 ng/mL. This study showed plastic could be a significant source of PAHs in sea turtles and the first to detect PAHs in sea turtle GI fluid. Loggerhead sea turtles are a long living species and could accumulate high concentrations of these endocrine-disrupting chemicals throughout their lifetime.

    It is cytogenetically difficult to distinguish between host and donor cells in allogeneic bone marrow transplantation (BMT) individuals of the same sex. Here we describe a patient with a cytogenetic marker found after BMT. A 7-month-old male presented with leukemia which was CD7+, CD33+, HLADR+, and CD4-, CD8-, indicating a diagnosis of acute stem cell leukemia (ASCL). Cytogenetic analysis revealed an abnormal clone in all of the cells analyzed: 46,XY,t(2;8)(p11.2;q24),inv(9)(p13p24). This translocation is associated with B-cell acute lymphoblastic leukemia (ALL); thus, it was possible for this patient to develop B-cell ALL. The abnormal clone persisted along with normal 46,XY cells, and evolved in several of seven additional analyses. The patient was treated with two courses of chemotherapy and failed to attain cytogenetic remission. While in relapse, the patient received a BMT from his 3-year-old brother. Two weeks later, a different translocation was seen in all cells: 46,XY,t(3;12)(p21;q21). This result could be interpreted in two ways: (1) the structural abnormality was indicative of a newly evolved clone related to the patient`s disease; or (2) the donor was a balanced translocation carrier. Cytogenetic analysis of peripheral blood from the donor revealed the same translocation seen in the patient. Parental blood chromosomes were normal indicating that the donor carried a de novo balanced translocation. Subsequent chromosome analysis of both peripheral blood and BM from the patient revealed the presence of the translocation in all cells. De novo balanced translocations are rare and occur with a frequency of 1/2,000 live borns. The family received genetic counseling and was informed of the possible reproductive risks to translocation carriers. This unusual finding will serve as a useful cytogenetic marker to assist in monitoring the patient`s clinical course, i.e., chimerism and remission status.

  2. Extensive horizontal transfer of core genome genes between two Lactobacillus species found in the gastrointestinal tract

    Full Text Available Abstract Background While genes that are conserved between related bacterial species are usually thought to have evolved along with the species, phylogenetic trees reconstructed for individual genes may contradict this picture and indicate horizontal gene transfer. Individual trees are often not resolved with high confidence, however, and in that case alternative trees are generally not considered as contradicting the species tree, although not confirming it either. Here we conduct an in-depth analysis of 401 protein phylogenetic trees inferred with varying levels of confidence for three lactobacilli from the acidophilus complex. At present the relationship between these bacteria, isolated from environments as diverse as the gastrointestinal tract (Lactobacillus acidophilus and Lactobacillus johnsonii and yogurt (Lactobacillus delbrueckii ssp. bulgaricus, is ambiguous due to contradictory phenotypical and 16S rRNA based classifications. Results Among the 401 phylogenetic trees, those that could be reconstructed with high confidence support the 16S-rRNA tree or one alternative topology in an astonishing 3:2 ratio, while the third possible topology is practically absent. Lowering the confidence threshold for trees to be taken into consideration does not significantly affect this ratio, and therefore suggests that gene transfer may have affected as much as 40% of the core genome genes. Gene function bias suggests that the 16S rRNA phylogeny of the acidophilus complex, which indicates that L. acidophilus and L. delbrueckii ssp. bulgaricus are the closest related of these three species, is correct. A novel approach of comparison of interspecies protein divergence data employed in this study allowed to determine that gene transfer most likely took place between the lineages of the two species found in the gastrointestinal tract. Conclusion This case-study reports an unprecedented level of phylogenetic incongruence, presumably resulting from extensive

    This study introduces the detailed geometry and kinematics of recently found Quaternary fault in southern Korea, named Seooe Fault, and discusses its tectonic implication through a synthetic analysis with previous studies. The N-S striking Seooe Fault shows a top-to-the-east thrust geometry and cuts the Cretaceous Goseong Formation and overlying Quaternary deposits, and its slip senses and associated minor folds in the hanging wall indicate an E-W compressional stress. The age of the lower part of the Quaternary deposits obtained by OSL dating indicates that the last movement of the fault occurred after 61 60 ka. Arcuate geometry of the main fault showing an upward decreasing dip-angle, reverse offset of the fault breccias, and reverse-sense indicators observed on neighboring N-S striking high-angle fractures indicate that this Quaternary fault was produced by the reactivation of pre-existing fault under E-W compressional stress field. Using the apparent vertical displacement of the fault and the attitudes of cutting slope and main fault surface, its minimum net displacement is calculated as 2.17 m. When the value is applied to the empirical equation of maximum displacement - moment earthquake magnitude (Mw), the magnitude is estimated to reach about 6.7, assuming that this displacement was due to one seismic event. Most of the Quaternary faults in southern Korea are observed along major inherited fault zones, and their geometry and kinematics indicate that they were reactivated under ENE-WSW or E-W compressional stress field, which is concordant with the characteristics of the Seooe Fault. In addition, focal mechanism solutions and geotechnical in-situ stress data in and around the Korean peninsula also support the current ENE-WSW or E-W regional compression. On the basis of the regional stress trajectories in and around East Asia, the current stress field in Korean peninsula is interpreted to have resulted from the cooperation of westward shallow subduction of

    The invasive eel parasite Anguillicoloides crassus (syn. Anguillicola crassus) is considered one of the major causes for the decline of the European eel (Anguilla anguilla) panmictic population. It impairs the swim bladder function and reduces swimming performance of its host. The life cycle of this parasite involves different intermediate and paratenic hosts. Despite an efficient immune system of the paratenic fish hosts acting against infections with A. crassus, levels of parasitized eels remain high in European river systems. Recently, the round goby Neogobius melanostomus (Gobiidae) has become dominant in many rivers in Europe and is still spreading at a rapid pace. This highly invasive species might potentially act as an important, so far neglected paratenic fish host for A. crassus. Based on own observations and earlier single sightings of A. crassus in N. melanostomus, 60 fresh individuals of N. melanostomus were caught in the Rhine River and examined to assess the infection levels with metazoan parasites, especially A. crassus. Glycerin preparations were used for parasite identification. The parasite most frequently found in N. melanostomus was the acanthocephalan Pomphorhynchus sp. (subadult stage) which occurred mainly encysted in the mesenteries and liver. Every third gobiid (P = 31.7%) was infected by A. crassus larvae (L3) which exclusively occurred inside the acanthocephalan cysts. No intact or degenerated larvae of A. crassus were detected elsewhere in the goby, neither in the body cavity and mesenteries nor in other organs. Affected cysts contained the acanthocephalan larvae and 1-12 (mI =3) living A. crassus larvae. Additionally, encysted larvae of the nematode Raphidascaris acus were detected in the gobies, but only in the body cavity and not inside the acanthocephalan cysts. Based on our observations, we suggest that A. crassus might actively bypass the immune response of N. melanostomus by invading the cysts of acanthocephalan parasites of the

    Sugars are aldoses or ketoses with multiple hydroxy groups which have been elusive to spectroscopic studies. Here we report a rotational study of the aldopentose ribose. According to any standard textbook aldopentoses can exhibit either linear forms, cyclic five-membered (furanose) structures or six-membered (pyranose) rings, occurring either as α- or β- anomers depending on the orientation of the hydroxy group at C-1 (anomeric carbon). β-Furanose is predominant in ribonucleosides, RNA, ATP and other biochemically relevant derivatives, but is β-furanose the native form also of free ribose? Recent condensed-phase X-ray and older NMR studies delivered conflicting results. In order to solve this question we conducted a microwave study on D-ribose that, owing to ultrafast UV laser vaporization, has become the first C-5 sugar observed with rotational resolution. The spectrum revealed six conformations of free ribose, preferentially adopting β-pyranose chairs as well as higher-energy α-pyranose forms. The method also allowed for unambiguous distinction between different orientations of the hydroxy groups, which stabilize the structures by cooperative hydrogen-bond networks. No evidence was observed of the α-/β-furanoses or linear forms found in the biochemical derivatives. i) D. Šišak, L. B. McCusker, G. Zandomeneghi, B. H. Meier, D. Bläser, R. Boese, W. B.

  6. Urodele p53 tolerates amino acid changes found in p53 variants linked to human cancer

    2007-09-01

    Full Text Available Abstract Background Urodele amphibians like the axolotl are unique among vertebrates in their ability to regenerate and their resistance to develop cancers. It is unknown whether these traits are linked at the molecular level. Results Blocking p53 signaling in axolotls using the p53 inhibitor, pifithrin-α, inhibited limb regeneration and the expression of p53 target genes such as Mdm2 and Gadd45, suggesting a link between tumor suppression and regeneration. To understand this relationship we cloned the p53 gene from axolotl. When comparing its sequence with p53 from other organisms, and more specifically human we observed multiple amino acids changes found in human tumors. Phylogenetic analysis of p53 protein sequences from various species is in general agreement with standard vertebrate phylogeny; however, both mice-like rodents and teleost fishes are fast evolving. This leads to long branch attraction resulting in an artefactual basal emergence of these groups in the phylogenetic tree. It is tempting to assume a correlation between certain life style traits (e.g. lifespan and the evolutionary rate of the corresponding p53 sequences. Functional assays of the axolotl p53 in human or axolotl cells using p53 promoter reporters demonstrated a temperature sensitivity (ts, which was further confirmed by performing colony assays at 37°C. In addition, axolotl p53 was capable of efficient transactivation at the Hmd2 promoter but has moderate activity at the p21 promoter. Endogenous axolotl p53 was activated following UV irradiation (100 j/m2 or treatment with an alkylating agent as measured using serine 15 phosphorylation and the expression of the endogenous p53 target Gadd45. Conclusion Urodele p53 may play a role in regeneration and has evolved to contain multiple amino acid changes predicted to render the human protein defective in tumor suppression. Some of these mutations were probably selected to maintain p53 activity at low temperature. However

    Full Text Available In the context of a hunt for a postulated hormone that is tissue-mass inhibiting and reproductively associated, there is described probable relatedness to a granin protein. A 7–8 kDa polypeptide candidate (gels/MS appeared in a bioassay-guided fractionation campaign involving sheep plasma. An N-terminal sequence of 14 amino acids was obtained for the polypeptide by Edman degradation. Bioinformatics and molecular biology failed to illuminate any ovine or non-ovine protein which might relate to this sequence. The N-terminal sequence was synthesized as the 14mer EPL001 peptide and surprisingly found to be inhibitory in an assay in vivo of compensatory renal growth in the rat and modulatory of nematode fecundity, in line with the inhibitory hormone hypothesis. Antibodies were raised to EPL001 and their deployment upheld the hypothesis that the EPL001 amino acid sequence is meaningful and relevant, notwithstanding bioinformatic obscurity. Immunohistochemistry (IHC in sheep, rodents and humans yielded staining of seeming endocrine relevance (e.g. hypothalamus, gonads and neuroendocrine cells in diverse tissues, with apparent upregulation in certain human tumours (e.g. pheochromocytoma. Discrete IHC staining in Drosophila melanogaster embryo brain was seen in glia and in neuroendocrine cells, with staining likely in the corpus cardiacum. The search for the endogenous antigen involved immunoprecipitation (IP followed by liquid chromatography and mass spectrometry (LC–MS. Feedstocks were PC12 conditioned medium and aqueous extract of rat hypothalamus—both of which had anti-proliferative and pro-apoptotic effects in an assay in vitro involving rat bone marrow cells, which inhibition was subject to prior immunodepletion with an anti-EPL001 antibody—together with fruit fly embryo material. It is concluded that the mammalian antigen is likely secretogranin II (SgII related. The originally seen 7–8 kDa polypeptide is suggested to be a new proteoform

  8. Common Genetic Variants Found in HLA and KIR Immune Genes in Autism Spectrum Disorder

    Directory of Open Access Journals (Sweden)

    Anthony R Torres

    2016-10-01

    Full Text Available The common variant - common disease hypothesis was proposed to explain diseases with strong inheritance. This model suggests that a genetic disease is the result of the combination of several common genetic variants. Common genetic variants are described as a 5% frequency differential between diseased versus matched control populations. This theory was recently supported by an epidemiology paper stating that about 50% of genetic risk for autism resides in common variants. However, rare variants, rather than common variants, have been found in numerous genome wide genetic studies and many have concluded that the common variant—common disease hypothesis is incorrect. One interpretation is that rare variants are major contributors to genetic diseases and autism involves the interaction of many rare variants, especially in the brain. It is obvious there is much yet to be learned about autism genetics.Evidence has been mounting over the years indicating immune involvement in autism, particularly the HLA genes on chromosome 6 and KIR genes on chromosome 19. These two large multigene complexes have important immune functions and have been shown to interact to eliminate unwanted virally infected and malignant cells. HLA proteins have important functions in antigen presentation in adaptive immunity and specific epitopes on HLA class I proteins act as cognate ligands for KIR receptors in innate immunity. Data suggests that HLA alleles and KIR activating genes/haplotypes are common variants in different autism populations. For example, class I allele (HLA-A2 and HLA-G 14bp-indel frequencies are significantly increased by more than 5% over control populations (Table2. The HLA-DR4 Class II and shared epitope frequencies are significantly above the control populations (Table 2. Three activating KIR genes: 3DS1, 2DS1 and 2DS2 have increased frequencies of 15%, 22% and 14% in autism populations, respectively. There is a 6% increase in total activating KIR

  9. A possible mechanism for earthquakes found in the mantle wedge of the Nazca subduction zone

    Beneath Colombia, the Cauca cluster of intermediate-depth earthquakes extends for 200 km along the trench (3.5°N-5.5°N, 77.0°W-75.3°W) and, with 58 earthquakes per year with local magnitude ML >= 2.5, has a higher rate of seismicity than the subduction zone immediately to the north or south. By precisely locating 433 cluster earthquakes from 1/2010-3/2014 with data from the Colombian National Seismic Network, we found that the earthquakes are located both in a continuous Nazca plate subducting at an angle of 33°-43° and in the overlying mantle wedge. The mantle wedge earthquakes (12% of the earthquakes) form two isolated 40-km-tall columns extending perpendicular to the subducting slab. Using waveform inversion, we computed focal mechanisms for 69 of the larger earthquakes. The focal mechanisms are variable, but the intraslab earthquakes are generally consistent with an in-slab extensional stress axis oriented 25° counterclockwise from the down-dip direction. We suggest that the observed mantle wedge earthquakes are the result of hydrofracture in a relatively cool mantle wedge. This segment of the Nazca Plate is currently subducting at a normal angle, but Wagner et al. (2017) suggested that a flat slab slowly developed in the region between 9-5.9 Ma and persisted until 4 Ma. During flat slab subduction, the overlying mantle wedge typically cools because it is cut off from mantle corner flow. After hydrous minerals in the slab dehydrate, the dehydrated fluid is expelled from the slab and migrates through the mantle wedge. If a cool mantle wedge remains today, fluid dehydrated from the slab may generate earthquakes by hydrofracture, with the mantle wedge earthquakes representing fluid migration pathways. Dahm's (2000) model of water-filled fracture propagation in the mantle wedge shows hydrofractures propagating normal to the subducting slab and extending tens of km into the mantle wedge, as we observe.

    Early school start times may curtail children's sleep and inadvertently promote sleep restriction. The current study examines the potential implications for early school start times for behavioral problems in public elementary schools (student ages 5-12 years) in Kentucky. School start times were obtained from school Web sites or by calling school offices; behavioral and disciplinary problems, along with demographic information about schools, were obtained from the Kentucky Department of Education. Estimated associations controlled for teacher/student ratio, racial composition, school rank, enrollment, and Appalachian location. Associations between early school start time and greater behavioral problems (harassment, in-school removals, suspensions, and expulsions) were observed, although some of these associations were found only for schools serving the non-Appalachian region. Findings support the growing body of research showing that early school start times may contribute to student problems, and extend this research through a large-scale examination of elementary schools, behavioral outcomes, and potential moderators of risk.

    In an agreeable shadow of the great 650th anniversary of Charles University foundation (1348-1998), arising of the first Institute of Sports Medicine round the world on Medical Faculty in Prague (1948-1998) was commemorated by scientific session. Since J. E. Purkynĕ (1850) have gone idea of favourable effect of body training for human health by representatives of Prague Medical Faculty, till Doctor J. Král, who started lectures for medical students in this discipline in 1933. Rise of Institute of Sports Medicine was approved in 1934, but its realization thanks to Professor Král, was performed after 2nd World War in 1948. From the beginning, students have lectures within the framework of daily study of whole wide of the branche, including practical exercises and closing examine. First text book of sports medicine and first book about clinic in sports medicine was written (J. Král). Members of Institute lectured on many foreign universities and scientific congresses and published more than 2,500 scientific works, some of them have world priority. For example first wireless transmission of heart frequency (V. Seliger, V. Kruta), cardiologic observations during big sports load (J. Král, Z. Hornof), discoveries at biochemical laboratory (J. Král, A. Zenísek), at medical functional anthropologic laboratory (V. Novotný), introducing of remedial exercises in clinical practice (L. Schmid, M. Zintlová, J. Chrástek) etc. In the set out choice of literary citation it is put on only fragment of publications which document scientific activity of jubileeing Institute. For period of duration of Institute more than hundred thousand patients were examined--both sportives and non-sportives, young and old. Contemporary trend goes from classic care about sportsmen towards preventive medicine. Attention is focused first of all to testing of middle aged and older patients in sense of prevention of cardiovascular and metabolic diseases and indication for specific movement load. In 650 years history of pedagogic and scientific success of Charles University, 50-year activity of Institute of Sports Medicine means only tiny part. In view of healthy risks, which brings modern life style and in view of worsening of environment, an important task stand before the discipline with new prevention conception.

  17. From Normal Schools to Primary Teaching Schools: historic journey of primary teachers’ training schools

    Full Text Available This article provides a brief outline of the teacher training schools in Portugal for what was traditionally known as primary education, starting in the second half of the nineteenth century, when such schools began functioning regularly.  Initially know as Primary Normal Schools, these institutions were renamed in 1930 to Primary Teaching Schools. In the second half of the 1980s, under full democracy, they were phased out, their place being taken by the Higher Schools of Education. In this article we seek to chronicle their evolution with a set of reflections on the ideals professed in their day, which are to be found primarily in training contexts and in textbooks. These principles deal mainly with such issues as the social roles to be played by the primary school teachers, the values inherent to the profession, pedagogical options considered to be legitimate and educational practices thought to be exemplary. We will analyse in particular the importance that the conceptions of the New School had in the construction of identity references during the republican period and their appropriation by the conservative pedagogy that circulated in the New State. We will also take into account the process of feminization, which left its own mark on the development of this teaching sector. Finally, we will outline a model of analysis for training institutions, using as our reference the case of Portugal.

For example, in our own solar system, we find evidence of certain short-lived radioactive nuclides (Aluminum 26 being the most well known). This implies the existence of a high-energy process late in the evolution of our solar system. If our solar system was immersed for a time in a sea of energetic particles, this could explain the rare nuclides present in meteorites found on the Earth today. RCW 38, at a distance of 6,000 light years from Earth, is one of the nearest star-forming regions with very young, hot stars.

    Weeks, William B; Wallace, Tanner A

    2008-01-01

    We wanted to determine whether the type of medical school attended--private US, public US, or foreign medical school--is associated with practice characteristics or incomes of physicians. Therefore, we used survey responses obtained during the 1990s from 10,436 actively practicing white male physicians who worked in one of 13 medical specialties and who graduated from a public US (5,702), private US (3,797), or international (937) medical school. We used linear regression modeling to determine the association between type of medical school attended and physicians' annual incomes after controlling for specialty, work hours, provider characteristics, and practice characteristics. We found that, for most specialties, international medical school graduates worked longer hours, were less likely to be board certified, had practiced medicine for fewer years, and were less likely to work in rural settings than US medical school graduates. After controlling for key variables, international medical school graduates' annual incomes were 2.6 percent higher (95% CI: 0.1%, 4.4%, p = .043) and public US medical school graduates' were 2.2 percent higher (95% CI: -0.9% -6.1%, p = 0.2) than private US medical school graduates' incomes. Because of their lower tuition expenses, international and public US medical school graduates may experience higher returns on educational investment than their counterparts who graduated from private US medical schools.

    Full Text Available The aims in this research were to determine the perceptions of school climate held by educators of primary schools in the southern Cape. Six primary schools with a staff complement of 178 educators participated in the investigation. Two instruments were used: the Organisational Climate Description Questionnaire Rutgers Elementary (OCDQ-RE and Dimensions of Organisational Health Inventory of Elementary Schools (OHI-E. The results indicated that primary school educators in the southern Cape perceived their relations with their principals as closed, while educator-educator relations were perceived as more open. An engaged school climate was taken as the typical prototype for the relevant primary schools. Average health profiles were drawn for the overall organisational health of primary schools. A significant relationship was found between primary schools' perceptions of organisational climate and organisational health. A significant difference was found between perceptions held by educators from different primary schools regarding the various dimensions of organisational climate and health. These findings have significant implications for the implementation of change in schools, educators' job satisfaction, motivation, productivity, well-being, and learner achievement.

    This paper presents a comparison between the instruction in international school and state school in the middle level in Indonesia to find out the strength and weakness of each school in order to identify some professional development needs. The observation and interview were conducted to see the instruction of each school. Some pedagogy aspects consisting of attitude, strategy, and practice were observed to get the overview of instruction. Through this study, it has been found that the teachers apply an active learning approach that created an enthusiastic atmosphere of students’ participation. However, the different circumstance found is in the aspect of the number of students, the language of instruction and students’ characteristics between those schools.

    Parents' attitudes about their children's schools matter. Their views can shape their children's attitudes about school, affect their levels of family-school engagement, and influence their residential and school enrollment decisions. In this article, we describe the development of a survey scale to assess parent perceptions of the climate of their child's school. Our comprehensive scale development process incorporated feedback from academics and potential respondents from the outset of the design process to enhance scale quality. We conducted 3 studies with national samples of parents (n = 385; n = 253; n = 266) to gather evidence of scale score reliability and valid score inferences based on convergent and discriminant validity. Through confirmatory factor analysis, we identified a theoretically grounded factor structure that fit the data well but found no evidence that parental response patterns distinguish between academic and social elements of school climate. Furthermore, we found that parents of younger children, on average, had a more positive perception of the school's climate than did parents of older children. We conclude by discussing how researchers and Pre-K-12 schools and districts can use the scale to aid school improvement efforts. 2014 APA

    Background: Schools are important settings for the promotion of a healthy diet and sufficient physical activity and thus overweight prevention. Objective: To assess differences in school nutrition environment and body mass index (BMI) in primary schools between and within 12 European countries. Methods: Data from the World Health Organization (WHO) European Childhood Obesity Surveillance Initiative (COSI) were used (1831 and 2045 schools in 2007/2008 and 2009/2010, respectively). School personnel provided information on 18 school environmental characteristics on nutrition and physical activity. A school nutrition environment score was calculated using five nutrition-related characteristics whereby higher scores correspond to higher support for a healthy school nutrition environment. Trained field workers measured children’s weight and height; BMI-for-age (BMI/A) Z-scores were computed using the 2007 WHO growth reference and, for each school, the mean of the children’s BMI/A Z-scores was calculated. Results: Large between-country differences were found in the availability of food items on the premises (e.g., fresh fruit could be obtained in 12%−95% of schools) and school nutrition environment scores (range: 0.30−0.93). Low-score countries (Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania) graded less than three characteristics as supportive. High-score (≥0.70) countries were Ireland, Malta, Norway, Portugal, Slovenia and Sweden. The combined absence of cold drinks containing sugar, sweet snacks and salted snacks were more observed in high-score countries than in low-score countries. Largest within-country school nutrition environment scores were found in Bulgaria, Czech Republic, Greece, Hungary, Latvia and Lithuania. All country-level BMI/A Z-scores were positive (range: 0.20−1.02), indicating higher BMI values than the 2007 WHO growth reference.

    The first Polish Higher Mining School was founded in 1816 in Kielce. The historical background of its foundation is described, curricula are outlined, prominent professors and graduates named. The significance of this School for Polish geology, mining and metallurgy to the present day is stressed. The School was closed in 1826 and the next Mining School to contine its traditions was instituted not earlier than in 1889 in Dabrowa Gornicza. It was also known as the Mine Foreman or Mine Deputy School (Sztygarka). This School was closed in 1905, reopened in 1910 and closed again in 1914. After Poland regained independence in 1919 the School flourished for 20 years. During the Second World War the teaching staff and student body were decimated and facilities destroyed. After 1945 the School was rebuilt and developed into an engineering school as a branch of the Academy of Mining and Metallury in Cracow by 1968 and a branch of the Silesian Politechnical between 1968 and 1984. In 1985 the School was taken over by the Ministry of Mining and Power Engineering and reorganized as a mining trade school. The Mining School in Dabrowa Gornicza, where several prominent professors of geology and managers of Polish geological and mining enterprises began their careers, contributed greatly to the development of geology in Poland. 12 refs.

  8. Approaches to School Leadership in Inclusive STEM High Schools: A Cross-Case Analysis

    Science.gov (United States)

    Ford, Michael Robert

    Inclusive STEM-focused high schools (ISHSs) are a relatively new phenomenon in the landscape of public education. This study of four exemplar ISHSs (identified by experts in STEM education as highly successfully in preparing students underrepresented in STEM for STEM majors in college and future STEM careers) provides a rich description of the approach to ISHS school leadership by identifying various internal and external leadership factors influencing school leadership. This study examined an existing data set that included site visits to four ISHSs along with pre- and post-visit data, and a cross-case analysis focused on the leadership contributions of ISHS leaders and their larger community. This study found that the ISHSs expanded the concept of school leadership to include leadership both within and outside the school. In addition, school leaders needed autonomy to innovate and respond to their schools' needs. This included autonomy in hiring new teachers, autonomy from school district influence, and autonomy from restrictive teachers' union regulation and policies. Finally, ISHSs needed to continually invest in increasing their schools' capacities. This included investing in teacher professionalization, providing pathways for school leadership, collaborating with business and industry, and identifying the best student supports. A product of this study was a proposition for characterizing school leadership in an ISHS. This proposition may offer valuable insight, implications, and information for states and schools districts that may be planning or improving STEM education programs.

    Objective To determine factors that characterizes school environments and their relationship with student learning, welfare and health. Method This is a case study supported by a comprehensive qualitative paradigm applied to classroom ecology. The fieldwork was carried out in six public schools for students in economic strata one and two that use computers in virtual classrooms. The information was collected through field journals, film recordings, observation, and recordings of interviews. The information was analyzed by categories in open general and focused cycles. Results The virtual era has enriched the debate about the importance of the environment in pedagogical processes. Nonetheless, the emergence of new diseases is a risk which students are exposed to. Pollution and overcrowding factors prevail in traditional classroom activities, while in the computer rooms the environment is healthier. Hence the need to incorporate these issues into the curriculum reforms and action plans to guide healthy living of schoolchildren and their families. Despite budget constraints, innovative ideas and projects were found. Schools have developed free preventive and corrective strategies such as workshops, talks and lectures by invited specialists, trainees, and students writing theses. They have also introduced controlled Internet access. Conclusion The educational community understands that the concept of health is at the heart of a comprehensive concept of education. In addition, classroom ecology has determining implications for learning and living together in pleasant and healthy environments that are incorporated into institutional educational projects.

    Full Text Available Procrastination is a trait and/or a form of behavior that denotes an individual’s delay in an activity which should be done, and which causes discomfort. In the study we wished to determine the differences between high school students regarding gender, educational programme and learning success of the previous school year in three factors. On a sample of 284 high school students of different Slovenian secondary schools, we found that on average boys show statistically significantly more shortage of learning self-discipline than girls, while girls, on average, significantly more discomfort than boys. Comparison of secondary school students between programmes showed that, on average, gimnazija students show significantly more learning self-discipline than students in secondary technical education. The comparison in relation to different levels of learning success at the end of the previous school year and the factors of procrastination showed, however, no statistically significant differences.

    Participants were 204 academically at-risk Latino students recruited into a study when in first grade and followed for 9 years. Using piecewise latent growth curve analyses, we investigated trajectories of teacher-rated behavioral engagement and student-reported school belonging during elementary school and middle school and the association between trajectories and enrollment in bilingual education classes in elementary school and a change in school ethnic congruence across the transition to middle school. Overall, students experienced a drop in school belonging and behavioral engagement across the transition. A moderating effect of ethnic congruence on bilingual enrollment was found. A decline in ethnic congruence was associated with more positive trajectories for students previously enrolled in bilingual classes but more negative trajectories for non-bilingual students.

    Full Text Available This study explores the opportunities and challenges of women who own low-fee private schools in three West African nations. With the implementation of the Millennium Development Goals (MDGs in 2000 and the Sustainable Development Goals in 2016, it has become obvious to policymakers that school leadership needs to be a policy priority around the world. Increased school autonomy and a greater focus on schooling and school results have made it essential to understand and support the role of school leaders. Few countries however have strong and systematic initiatives to professionalize school leadership and to nurture and support current school leaders. This becomes even more complex for governments given the rise of private schooling in low and middle-income countries worldwide; thus, it is crucial for governments to understand the importance of leadership at the school level and how to nurture and professionalize it. In this study, the authors examine the roles of women school leaders in Burkina Faso, Ghana, and Liberia within the context of MDG 3: promote gender equality and empower women. Because of the many challenges in the public sector in education in low and middle-income countries, the private sector has responded by creating thousands of small businesses. Since a large and growing number of women are leading these private schools, this study presents the findings on the nature of the leadership of these women entrepreneurs. Fourteen school proprietors participated in face-to face interviews about their reasons for founding a school as well as the supports and challenges they face. Findings discuss the limited professional learning opportunities for school leaders in these nations. The study describes the school leaders’ desires to help build their nations, and the unique cultural and contextual factors in each country.

    Full Text Available This descriptive study used nonparametric (Kruskal–Wallis and Mann–Whitney U tests to determine the efficacy of New York City (NYC small school initiative. A sample of 369 NYC high schools was tested on various performance indicators. The results: Large schools generated statistically significant higher performance scores and were more effective at preparing students for college and careers. On the New York State (NYS English language arts (ELA test, a Mann–Whitney U found statistically significant difference between scores for small school (median = 2.62, n = 213 and large school (median = 2.81, n = 58, U = 3200.00, z = −5.63, p = .001, r = −.34. On the state’s math test, a Mann–Whitney U found statistically significant difference between scores for small school (median = 2.76, n = 213 and large school (median = 3.12, n = 58, U = 3086.00, z = −5.84, p = .000, r = −.35. On NYC Department of Education (NYCDOE–assigned college and career readiness scores (CCRS, a Mann–Whitney U found statistically significant difference between CCRS for small school (median = 3.00, n = 213 and large school (median = 3.00, n = 58, U = 4705.50, z = −2.90, p = .004, r = −.018. The evidence suggests the city reconfigured large failing schools into smaller ones, resulting in the concentration of poverty (through the placement of mostly low socioeconomic status [SES] and underperforming Black and Hispanic students in those schools. Recommendations include future studies exploring the effect of mediating and moderating factors.

    Character strengths have been found to be substantially related to children's and adolescents' well-being. Initial evidence suggests that they also matter for school success (e.g., Weber and Ruch, 2012). The present set of two studies aimed at replicating and extending these findings in two different age groups, primary school students (N = 179; mean age = 11.6 years) and secondary school students (N = 199; mean age = 14.4 years). The students completed the VIA-Youth (Values in Action Inventory of Strengths for Youth), a self-report measure of the 24 character strengths in the VIA classification. Their teachers rated the students' positive behavior in the classroom. Additionally, school achievement was assessed: For the primary school students (Study 1), teachers rated the students' overall school achievement and for the secondary school students (Study 2), we used their grades as a measure of school achievement. We found that several character strengths were associated with both positive classroom behavior and school achievement. Across both samples, school achievement was correlated with love of learning, perseverance, zest, gratitude, hope, and perspective. The strongest correlations with positive classroom behavior were found for perseverance, self-regulation, prudence, social intelligence, and hope. For both samples, there were indirect effects of some of the character strengths on school achievement through teacher-rated positive classroom behavior. The converging findings from the two samples support the notion that character strengths contribute to positive classroom behavior, which in turn enhances school achievement. Results are discussed in terms of their implications for future research and for school interventions based on character strengths.

    Full Text Available Poetycka antropologia Julii Hartwig [Julia Hartwig’s poetic anthropology] written by Marcin Terlecki is a book that fills the yawning gap in our literary understanding of the twentieth century Polish poetry and constitutes the first attempt at a comprehensive and detailed presentation of the lyrical works by J. Hartwig. The modern collection in which the work appears allow M. Terlecki to reveal the poetess’ fundamental insights dominating and underlying her world outlook and epistemological views. This, in turn, puts him in a position to give an explanation to the logic embedded in the evolution under scrutiny. M. Terlecki convincingly supports his own argument concerning J. Hartwig’s poetic reception of the world proving the thesis that its fundamentals are deeply rooted in the anthropological perspective. Terlecki differentiates the latter into three basic categories. First, there is “strangeness/alienation”, which results in the need for self-definition (determination of one’s nature and basic qualities. Then, “identity”, whose reflection turns out to be not only what is different in its external shape, but also what is different inside — within the plane of one’s own culture, biography and personality. And, finally, “empathy”, born out of questions on a feasibility of contact with what is different, alien and absent. The three categories, connected by the logic of anthropological vision, are presented as basic and fundamental for the subsequent stages in Hartwig’s poetical output. At the same time, they reveal themselves as axes of anthropological reading material provided by the author — for the discussed book is the author’s own research project on “poetic anthropology”.
