    Pressler, Emily; Raver, C. Cybele; Friedman-Krauss, Allison H.; Roy, Amanda

    2016-01-01

    Low-income students are at increased risk for grade retention and suspension, which dampens their chances of high school graduation, college attendance, and future success. Drawing from a sample of 357 children and their families who participated in the Chicago School Readiness Project, we examine whether greater exposure to cumulative poverty-related risk from preschool through 5th grade is associated with greater risk of student retention and suspension in 6th grade. Logistic regression results indicate that exposure to higher levels of cumulative risk across the elementary school years is associated with students’ increased risk of retention in 6th grade, even after controlling for child school readiness skills and other covariates. Importantly, findings of the association between average cumulative risk exposure and student suspension are more complex; the role of poverty-related risk is reduced to non-significance once early indicators of child school readiness and other covariates are included in regression models. While, children’s early externalizing behavior prior to kindergarten places children at greater risk of suspension 7 years later, children’s higher levels of internalizing behaviors and early math skills are associated with significantly decreased risk of suspension in the 6th grade. Together, findings from the study suggest the complex ways that both early school readiness and subsequent exposure to poverty-related risk may both serve as compelling predictors of children’s likelihood of “staying on track” academically in the 6th grade.

  14. Improving 6th Grade Climate Literacy using New Media (CLINM) and Teacher Professional Development

    NASA Astrophysics Data System (ADS)

    Smith, G.; Schmidt, C.; Metzger, E. P.; Cordero, E. C.

    2012-12-01

    The NASA-funded project, Improving 6th Grade Climate Literacy using New Media (CLINM), is designed to improve the climate literacy of California's 450,000 6th-grade students through teacher professional development that presents climate change as an engaging context for teaching earth science standards. The project fosters experience-based interaction among learners and encourages expressive creativity and idea-exchange via the web and social media. The heart of the CLINM project is the development of an online educator-friendly experience that provides content expert-reviewed, teacher-tested, standards-based educational resources, classroom activities and lessons that make meaningful connections to NASA data and images as well as new media tools (videos, web, and phone applications) based on the Green Ninja, a climate-action superhero who fights global warming by inspiring personal action (www.greenninja.info). In this session, we will discuss this approach to professional development and share a collection of teacher-tested CLINM resources. CLINM resources are grounded in earth system science; classroom activities and lessons engage students in exploration of connections between natural systems and human systems with a particular focus on how climate change relates to everyone's need for food, water, and energy. CLINM uses a team-based approach to resource development, and partners faculty in San José State University's (SJSU) colleges of Science, Education, and Humanities and the Arts with 6th-grade teachers from local school districts, a scientist from NASA Ames Research Center and climate change education projects at Stanford University, the University of Nebraska at Lincoln, and the University of Idaho. Climate scientists and other content experts identify relevant concepts and work with science educators to develop and/or refine classroom activities to elucidate those concepts; activities are piloted in pre-service science methods courses at SJSU and in

  16. Latina girls' identities-in-practice in 6th grade science

    NASA Astrophysics Data System (ADS)

    Tan, Edna

    Inequalities and achievement gaps in science education among students from different racial and socioeconomic backgrounds as well as between genders in the United States are due to not just access to resources, but also to the incongruence between identities of school science with identities salient to minority students. Minority girls are especially portrayed to be estranged from prototypical school science Discourse, often characterized as white, middle class, and masculine. This dissertation, based on a two-year ethnographic study in an urban middle school in New York City, describes the authoring of novel identities-in-practice of minority girls in a 6th grade science classroom. The findings indicate that minority girls draw from out-of-school identities salient to them to author novel identities-in-practice in the various figured worlds of the 6th grade science classroom. Through taking such authorial stances, minority girls exhibit agency in negotiating for wider boundaries in their school science participation and broker for hybrid spaces of school science where the school science Discourse was destabilized and challenged to be more inclusive of everyday funds of knowledge and Discourses important to the students. The findings also highlight the dialectic relationship between an individual students' learning and participation and the school science community-of-practice and the implications such a relationship has on the learning of both individual students and the collective community-of-practice. From year one findings, curricular adaptations were enacted, with teacher and student input, on lessons centering on food and nutrition. The adapted curriculum specifically solicited for nontraditional funds of knowledge and Discourse from students and were grounded strongly in relevance to students' out of school lives. The hybrid spaces collectively brokered for by the community-of-practice were transformed in three ways: physically, politically, and

  8. Integration of physical activity and technology motion devices within a combined 5th and 6th grade science curriculum

    NASA Astrophysics Data System (ADS)

    Finn, Kevin Eugene

    Background: National recommendations to increase school-based physical activity and promote academic success advise incorporating movement into traditional classroom lessons. Classroom-based physical activities have favorable associations with indicators of cognitive functioning, academic behaviors, and academic achievement. Purpose: This study analyzed the Active Science framework, which incorporated school-based physical activity within interactive science classroom lessons. Specifically, the study measured the effects of the Active Science framework on student physical activity levels in the classroom, student learning of science inquiry skills and content knowledge, and student perceptions of physical activity and science. A secondary purpose was to evaluate the teachers' perceptions on the implementation of the framework. Subjects: Participants were 37 Hispanic girls (age=11.1 +/-0.8 yr) in mixed 5th/6th grade science classes in a private, urban middle school. Methods: Physical activity levels of the students during the Active Science framework were measured using pedometers and heart rate monitors. Pre- and post-tests were used to assess the levels of learning achieved by the students in science inquiry skills and content during the Active Science framework. Student perceptions and attitudes toward science and physical activity were measured during student focus groups and pre-post perception surveys. Lesson plan evaluations completed by the teachers and structured interviews provided data on implementation of the framework. Results: Physical activity results showed heart rate (146 +/-9 bpm); maximal heart rate (196 +/-10.6 bpm); time (35 +/-2.5 mins); steps (3050 +/-402.7); calories (99 +/-8.4 kcal); and distance (1.1 +/-0.2 miles) while performing the activity portion of the science lessons were consistent with national recommendations for accumulating school-based physical activity.

    As climate change intensifies, increased temperatures and altered precipitation will make water, a limited resource in the arid southwestern United States, even scarcer in many locations. The USDA Southwest Regional Climate Hub (SWRCH) developed Climate Change and the Water Cycle, an engaging and scientifically rigorous education unit for 6th -12th grade students. The unit is aligned with Common Core State Standards and Next Generation Science Standards. Nine activities can be conducted over 10 instruction hours. Each activity can also stand alone. In partnership with SWRCH, the Asombro Institute for Science Education developed the unit. Each activity was reviewed by an educator for educational practices and by a scientist for scientific accuracy. The unit was pilot tested with 524 students in 2014, and pre- and post-tests were administered. Ninety-one percent of students were able to name a greenhouse gas on the post-test, compared to only 48% on the pre-test. On the post-test, 86% of students identified the relationship between average global temperature and carbon dioxide levels in the atmosphere, compared to only 52% on the pre-test. A student commented: "I loved all of the activities! They are fun and help us understand about what goes on in the world." Educators who participated in pilot testing said: "the entire curriculum is great, but I was particularly impressed with the progression of ideas and the variety of lessons," and "students could see the relevance and importance of these real life issues." Anyone interested in using the unit to host workshops for teachers in southwestern states should contact Asombro for more information (information@asombro.org). The Climate Change and the Water Cycle 6th-12th grade curriculum unit is available online: www.swclimatehub.info/education/climate-change-and-water-cycle

  10. Smoking practices, risk perception of smoking, and environmental tobacco smoke exposure among 6th-grade students in Ciudad Juárez, Mexico.

    2007-02-01

    This study assessed the smoking practices, risk perception of smoking, and environmental tobacco smoke (ETS) exposure among adolescents in Ciudad Juárez, Mexico. We used a cross-sectional method to examine the smoking practices, risk perception of smoking, and ETS exposure of 6th-grade students (N=506), aged 11-13 years, attending six randomly selected middle schools. Schools were classified by school setting (i.e., public vs. private) and socioeconomic status (SES; i.e., low, middle, or high). The results indicated that 6th-grade students attending a public, low-SES school setting in Ciudad Juárez not only exhibited significantly higher rates of ETS exposure at home and in public places (p<.01) but also were more likely to have tried smoking (p<.01) and to be current smokers (p<.01), and were less likely to support a ban on smoking in public places (p<.01), compared with students who attended a private school or a public, middle- or high-SES school setting. These results provide further evidence that public health interventions to prevent initiation of smoking and to assist in smoking cessation among adolescents and to reduce their ETS exposure at home and in public need to target all school-aged students, especially those attending school in a low-SES settings.

  12. STEM development: A study of 6th--12th grade girls' interest and confidence in mathematics and science

    NASA Astrophysics Data System (ADS)

    Heaverlo, Carol Ann

    Researchers, policymakers, business, and industry have indicated that the United States will experience a shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this shortage, one of which includes increasing the representation of girls and women in the STEM fields. In order to increase the representation of women in the STEM fields, it is important to understand the developmental factors that impact girls' interest and confidence in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). This study identifies factors that impact girls' interest and confidence in mathematics and science, defined as girls' STEM development. Using Bronfenbrenner's (2005) bioecological model of human development, several factors were hypothesized as having an impact on girls' STEM development; specifically, the macrosystems of region of residence and race/ethnicity, and the microsystems of extracurricular STEM activities, family STEM influence, and math/science teacher influence. Hierarchical regression analysis results indicated that extracurricular STEM involvement and math teacher influence were statistically significant predictors for 6--12th grade girls' interest and confidence in mathematics. Furthermore, hierarchical regression analysis results indicated that the only significant predictor for 6--12th grade girls' interest and confidence in science was science teacher influence. This study provides new knowledge about the factors that impact girls' STEM development. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of 6--12th grade girls.

    2014-02-01

    The purpose was to evaluate the reach, dose, and fidelity of Guys Only Activity for Life (G.O.A.L.), a 7-week pilot intervention conducted from February to March 2011 to increase 6th and 7th grade boys' moderate-to-vigorous physical activity (MVPA). One middle school was randomly assigned to the G.O.A.L. intervention and another from the same urban school district in the Midwestern U.S. to a comparison condition. Thirty boys, ages 10-14 years, participated in each school. The intervention, guided by the Health Promotion Model (HPM) and Self-Determination Theory (SDT), consisted of a 90-min after-school physical activity club 4 days/week and one motivational interviewing session with a registered (school) nurse. Data were gathered via attendance records, club observations, heart rate monitors, audio-taping of motivational interviewing sessions, and surveys. On average boys attended the club 2.11 days/week (SD=.86). A trained independent process evaluator reported that the physical activity club instructors provided the boys with the opportunity for a mean of 25.8 min/day of MVPA. Using a four-point Likert scale (1=disagree a lot; 4=agree a lot), the process evaluator perceived that the club was delivered with high fidelity and adherence to the underlying theories (M=3.48; SD=0.39). Sessions with the nurse lasted an average of 13 min, 29 s. All boys attended. Two trained independent coders indicated that the nurse demonstrated at least beginning proficiency for all tasks associated with motivational interviewing, with the exception of using sufficient open- as opposed to closed-ended questions and reflections compared to questions. Fidelity related to session delivery and adherence to the theories was high (M=3.83; SD=0.19). The process evaluation data indicated that strategies are needed to increase attendance and boys' MVPA during the club time.

The Health Behavior in School-Aged Children surveys of nationally representative samples of students in grades 6 through 10 were completed in 1998 (n = 15 686), 2002 (n = 14 818), 2006 (n = 9229), and 2010 (n = 10 926). We assessed frequency of bullying behaviors, physical fighting, and weapon carrying as well as weapon type and subtypes of bullying. We conducted logistic regression analyses, accounting for the complex sampling design, to identify trends and variations by demographic factors. Results. Bullying perpetration, bullying victimization, and physical fighting declined from 1998 to 2010. Weapon carrying increased for White students only. Declines in bullying perpetration and victimization were greater for boys than for girls. Declines in bullying perpetration and physical fighting were greater for middle-school students than for high-school students. Conclusions. Declines in most violent behaviors are encouraging; however, lack of decline in weapon carrying merits further attention. PMID:24825213

    The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design was used to investigate the treatment effect. There were 162 students in the experimental group and 142 students in the control group. Both the experimental and control group students took the Achievement Test in Reproduction, Development, and Growth in Living Things (RDGLT), Science Process Skills Test, and Attitudes Toward Science Questionnaire, as pre-test and post-test. Repeated analysis of variance design was used in analyzing the data. Both the experimental and control group students were taught in RDGLT units for 22 class hours. The results indicated the positive effect of guided-inquiry approach on the Turkish students' cognitive as well as affective characteristics. The guided inquiry enhanced the experimental group students' understandings of the science concepts as well as the inquiry skills more than the control group students. Similarly, the experimental group students improved their attitudes toward science more than the control group students as a result of treatment. The guided inquiry seems a transition between traditional teaching method and student-centred activities in the Turkish schools.

    Children in the United States are at risk for numerous psychological problems, such as anxiety, attention problems, and mood disorders, and are underserved by current mental health provisions. The current study is a pilot trial to examine the effects of a nonelective, classroom-based, teacher-implemented, mindfulness meditation intervention on standard clinical measures of mental health and affect in middle school children. A total of 101 healthy sixth-grade students (55 boys and 46 girls) were randomized to either an Asian history course with daily mindfulness meditation practice (intervention group) or an African history course with a matched experiential activity (active control group). Self-reported data was collected by administering the Youth Self Report (YSR), a modified Spielberger State-Trait Anxiety Inventory, and the Cognitive and Affective Mindfulness Measure -Revised before and after 6 weeks of meditation or active control condition. Both meditators and active controls decreased significantly on the YSR Internalizing Problems, Externalizing Problems, and Attention Problems subscales but did not differ in the extent of their improvements. Both groups also showed comparable improvements on measures in affect. Meditators were significantly less likely to develop suicidal ideation or thoughts of self-harm than controls. Improvements in affect were correlated with increases in mindfulness in meditators but not controls. These results suggest that mindfulness training may yield both unique and nonspecific benefits that are shared by other novel activities. PMID:24930819

    The extended abstracts which are submitted here present a summary of the proceedings of the 6th International Workshop/12th LH Gray Workshop: Microbeam Probes of Cellular Radiation Response, held at St. Catherine's College, University of Oxford, UK on March, 29th-31st, 2003. In 1993 the 4th LH Gray Workshop entitled ''Microbeam Probes of Cellular Radiation Response'' was held at the Gray Cancer Institute in Northwood. This was organized by Prof BD Michael, Dr M. Folkard and Dr KM Prise and brought together 40 participants interested in developing and applying new microbeam technology to problems in radiation biology (1). The workshop was an undoubted success and has spawned a series of subsequent workshops every two years. In the past, these workshops have been highly successful in bringing together groups interested in developing and applying micro-irradiation techniques to the study of cell and tissue damage by ionizing radiations. Following the first microbeam workshop, there has been a rapid growth in the number of centres developing radiobiology microbeams, or planning to do so and there are currently 15-20 worldwide. Much of the recent research using microbeams has used them to study low-dose effects and ''non-targeted'' responses such bystander effects, genomic instability and adaptive responses. The goal of the 6th workshop was to build on our knowledge of the development of microbeam approaches and the application to radiation biology in the future with the meeting stretching over a 3 day period. Over 80 participants reviewed the current state of radiobiology microbeam research worldwide and reported on new technological developments both in the fields of physics and biology.

    The posters presented at the 6th International Immunoglobulin Symposium covered a wide range of fields and included both basic science and clinical research. From the abstracts accepted for poster presentation, 12 abstracts were selected for oral presentations in three parallel sessions on immunodeficiencies, autoimmunity and basic research. The immunodeficiency presentations dealt with novel, rare class-switch recombination (CSR) deficiencies, attenuation of adverse events following IVIg treatment, association of immunoglobulin (Ig)G trough levels and protection against acute infection in patients with X-linked agammaglobulinaemia (XLA) and common variable immunodeficiency (CVID), and the reduction of class-switched memory B cells in patients with specific antibody deficiency (SAD). The impact of intravenous immunoglobulin on fetal alloimmune thrombocytopenia, pregnancy and postpartum-related relapses in multiple sclerosis and refractory myositis, as well as experiences with subcutaneous immunoglobulin in patients with multi-focal motor neuropathy, were the topics presented in the autoimmunity session. The interaction of dendritic cell (DC)-SIGN and alpha2,6-sialylated IgG Fc and its impact on human DCs, the enrichment of sialylated IgG in plasma-derived IgG, as wells as prion surveillance and monitoring of anti-measles titres in immunoglobulin products, were covered in the basic science session. In summary, the presentations illustrated the breadth of immunoglobulin therapy usage and highlighted the progress that is being made in diverse areas of basic and clinical research, extending our understanding of the mechanisms of immunoglobulin action and contributing to improved patient care.

    2015-07-01

    The IL-17A producing T-helper-17 (Th17) cell population plays a major role in rheumatoid arthritis (RA) pathogenesis and has gained wide interest as treatment target. IL-17A expressing Th cells are characterized by the expression of the chemokine receptor CCR6 and the transcription factor RORC. In RA, CCR6+ Th cells were identified in peripheral blood, synovial fluid and inflamed synovial tissue. CCR6+ Th cells might drive the progression of an early inflammation towards a persistent arthritis. The CCR6+ Th cell population is heterogeneous and several subpopulations can be distinguished, including Th17, Th22, Th17.1 (also called non-classic Th1 cells), and unclassified or intermediate populations. Interestingly, some of these populations produce low levels of IL-17A but are still very pathogenic. Furthermore, the CCR6+ Th cells phenotype is unstable and plasticity exists between CCR6+ Th cells and T-regulatory (Treg) cells and within the CCR6+ Th cell subpopulations. In this review, characteristics of the different CCR6+ Th cell populations, their plasticity, and their potential impact on rheumatoid arthritis are discussed. Moreover, current approaches to target CCR6+ Th cells and future directions of research to find specific CCR6+ Th cell targets in the treatment of patients with RA and other CCR6+ Th cell mediated autoimmune diseases are highlighted.

    The 6th International Conference on Emerging Zoonoses, held at Cancun, Mexico, 24-27 February 2011, offered 84 participants from 18 countries, a snapshot of current research in numerous zoonoses caused by viruses, bacteria or prions. Co-chaired by Professors Heinz Feldmann and Jürgen Richt, the conference explored 10 topics: (i) The ecology of emerging zoonotic diseases; (ii) The role of wildlife in emerging zoonoses; (iii) Cross-species transmission of zoonotic pathogens; (iv) Emerging and neglected influenza viruses; (v) Haemorrhagic fever viruses; (vi) Emerging bacterial diseases; (vii) Outbreak responses to zoonotic diseases; (viii) Food-borne zoonotic diseases; (ix) Prion diseases; and (x) Modelling and prediction of emergence of zoonoses. Human medicine, veterinary medicine and environmental challenges are viewed as a unity, which must be considered under the umbrella of 'One Health'. Several presentations attempted to integrate the insights gained from field data with mathematical models in the search for effective control measures of specific zoonoses. The overriding objective of the research presentations was to create, improve and use the tools essential to address the risk of contagions in a globalized society. In seeking to fulfil this objective, a three-step approach has often been applied: (i) use cultured cells, model and natural animal hosts and human clinical models to study infection; (ii) combine traditional histopathological and biochemical approaches with functional genomics, proteomics and computational biology; and (iii) obtain signatures of virulence and insights into mechanisms of host defense response, immune evasion and pathogenesis. This meeting review summarizes 39 of the conference presentations and mentions briefly the 16 articles in this Special Supplement, most of which were presented at the conference in earlier versions. The full affiliations of all presenters and many colleagues have been included to facilitate further inquiries

    Ramsey, Whitney J.

    The purpose of this study was to determine if there were differences in standardized test scores, expressed as percentage passing, in math, reading-language arts, science, and social studies by comparing 6th grade students in K--8 schools with those in 6--8 schools. The data were gathered from an analysis of 6th grade students' scores on the 2006--2007 TCAP standardized assessment test in the state of Tennessee. The relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient, proficient, or advanced level in each subject area was examined. The analysis was based on 5 research questions. A t-test for independent samples was used to identify the relationships between the independent variables, configuration of the school (K--8 or 6--8), and the dependent variables, the percent of students scoring below proficient, proficient, or advanced. A chi square analysis was used to identify the relationship between the proportion of K--8 schools meeting AYP versus the proportion of 6--8 schools meeting AYP. The study showed no relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient level in math, reading-language arts, and social studies. Similarly, there was not a significant difference between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the proficient level in math and reading-language arts and the advanced level in math, reading-language arts, and science. However, there was a significant relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient level and the proficient level in science and the percent of 6th grade students scoring at the proficient level and advanced level in social studies. In science, a lower percentage of 6th grade students in K--8 schools scored below proficient than did 6th grade students in 6--8 schools. In science, a higher

We found 23 cases in children reported in the literature; however, many of these cases followed immunization or were associated with viral illness. Here we report two cases of recurrent abducens nerve palsy with no obvious etiology. The diagnosis should be considered in any child who experiences abducens nerve palsy in the absence of any underlying pathology or precipitating factors.

  19. Effects of a rise in base level on graded streams

    What changes take place in a longitudinal river profile due to a rise in base level would seem to be a fundamental question in geomorphology, however, little has been accomplished toward answering this question, and the prevailing views are contradictory. Most authors say that a river will adjust its entire profile in response to a rise in base level. This misconception appears to have started in Elmo G. Harris' 1901 article, Effects of Dams and Like Obstructions in Silt-bearing Streams. The hypothesis became popular after publication of J. Hoover Mackin's classic 1948 paper, Concept of the Graded River. In the section Rise of Base Level'' Mackin explained that ''...the only generalization that can be made is that the new profile will be everywhere adjusted to the new prevailing conditions.'' Although Mackin's idea was a conceptual one, the concept has subsequently been taken literally. Contrary to this perception, the small amount of work that has been completed shows rivers will adjust their profiles only a short distance upstream from reservoir level. This may be due to the adjustment becoming infinitesimally small upstream and grading into the original profile so that the adjustment upstream is negligible. Unfortunately the misconception of stream aggradation in response to a rise in base level has prevailed for over 90 years and is widespread in the literature. Many textbooks, both introductory and advanced, from 1971 to the present, and some of the leading names in geomorphology have accepted the misconception without question.

    1996-03-01

    Finding low dimensional dynamical behavior in biological preparations has received much attention. Neurons are, however, subject to random processes, or "noise". Thus specific dynamical behavior is evidenced by well defined signatures embedded in noisy data files(D. Pierson and F. Moss Phys. Rev. Lett. 75, 2124 (1995)). We report the results of a statistical search for unstable periodic orbits in the periodically stimulated 6th ganglion of the crayfish Procambarus clarkii. Electrophysiological recordings from the caudal photoreceptor neuron within the ganglion provide the data. We discuss the results in terms of the cyclic theory of chaos.

    2015-01-01

    Biomarker measurement and LC-MS analysis of large molecule pharmaceuticals (LM-MS) are becoming increasingly important in pharmaceutical development, although they are not included in the existing bioanalytical method validation guidelines in Japan. The 6th Japan Bioanalysis Forum symposium presented challenges regarding biomarkers and LM-MS, as well as the current circumstances for regulated bioanalysis, by inviting speakers from Japan, the USA, European Union and Asia-pacific. Japan Bioanalysis Forum discussion groups also presented their outcomes and openly discussed these with the attendees - over 200 dedicated individuals from industry, regulatory agencies and academia. The symposium successfully reinforced the idea that fit-for-purpose approaches are necessary, and that science should drive any judgments and actions throughout drug development.

  5. Plasma amino acid response to graded levels of escape protein.

    1992-09-01

    A trial was conducted to examine the potential of using plasma amino acid responses to graded levels of escape protein to determine limiting amino acids in cattle. Growing calves (n = 120; mean BW = 220 +/- 21 kg) were fed a basal diet of corncob:sorghum silage (61:39) and were individually supplemented with distillers' dried grains (DDG), heat-damaged DDG (H-DDG), feather meal (FTH), or urea. The urea supplement was mixed with DDG and H-DDG to allow 0, 20, 35, 50, 65, or 80% of the supplemental CP to come from distillers' protein and maintain an 11.5% CP diet. Urea supplement was mixed with FTH to allow 0, 22, 39, 56, 73, or 90% of the supplemental CP to come from FTH. Dietary CP ranged from 11.5% at the 0% level to 17.3% at the 90% level. Plasma concentration of most essential plasma amino acids responded (P less than .10) linearly and(or) quadratically to increased escape protein. The broken-line response of plasma methionine at low DDG intake suggested that methionine was limiting at low levels of escape protein. An initial decrease followed by a plateau fit by a broken line indicated that histidine became limiting in FTH diets, and lysine eventually became limiting for DDG, H-DDG, and FTH diets before maximum BW gain was reached. Results indicate that plasma amino acid responses may identify amino acids that become limiting with increasing escape protein.

  9. Fundamentals of Physics, 6th Edition Enhanced Problems Version

    NASA Astrophysics Data System (ADS)

    Halliday, David; Resnick, Robert; Walker, Jearl

    2002-04-01

    No other text on the market today can match the success of Halliday, Resnick and Walker's Fundamentals of Physics. This text continues to outperform the competition year after year, and the new edition will be no exception. Intended for Calculus-based Physics courses, the 6th edition of this extraordinary text is a major redesign of the best-selling 5th edition, which still maintains many of the elements that led to its enormous success. Jearl Walker adds his unique style to this edition with the addition of new problems designed to capture, and keep, students' attention. Nearly all changes are based on suggestions from instructors and students using the 5th edition, from reviewer comments, and from research done on the process of learning. The primary goal of this text is to provide students with a solid understanding of fundamental physics concepts, and to help them apply this conceptual understanding to quantitative problem solving. The principal goal of Halliday-Resnick-Walker is to provide instructors with a tool by which they can teach students how to effectively read scientific material and successfully reason through scientific questions. To sharpen this tool, the Enhanced Problems Version of the sixth edition of Fundamentals of Physics contains over 1000 new, high-quality problems that require thought and reasoning rather than simplistic plugging of data into formulas.

    Ros, Eduardo; Porcas, Richard W.; Lobanov, Andrei P.; Zensus, J. Anton

    This volume contains the papers presented at the 6th Symposium of the European VLBI Network, held in Bonn on 25-28 June 2002. The initial aim of these biennial gatherings of European VLBI practitioners was to review in a timely manner new results and technical developments related to Very Long Baseline Interferometry. Now, however, interest and participation in the EVN Symposia reaches far beyond Europe, reflecting the fact that scientific research and development programs are carried out to a high degree in international and often truly global collaborations. More than 120 scientists from around the world registered for participation in the Symposium. The Symposium was hosted by the Max-Planck-Institut für Radioastronomie and was held at the Gustav Stresemann Institut. In addition to the scientific sessions and poster presentations, the program included an EVN Users Meeting, an MPIfR versus Rest-of-the-World football match (highly appropriate given the competing World Cup event!), a visit to the MPIfR's 100m radio telescope in Effelsberg, and a Conference Dinner held in the nearby old walled town of Bad Müunstereifel. To maximize the usefulness of these proceedings (and possibly as a daring precedent) the Editors decided to demand the written versions of talks and posters and to complete the editorial work before the meeting, and to deliver the book to the participants at the beginning of the Symposium. We thank the authors for their cooperation in delivering publication-ready electronic manuscripts and for meeting the strict deadlines. It is highly gratifying that only a handful of the 100 presentations are not represented in this volume. The editors have made minor changes to some of the contributions in order to improve readability, and take responsibility for any errors arising from these changes. Besides the authors, many individuals have contributed to the preparation of the meeting and its proceedings. In addition to many members of the MPIfR staff, we

  2. PREFACE: The 6th Nordic Meeting on Nuclear Physics

    NASA Astrophysics Data System (ADS)

    Løvhøiden, G.; Thorsteinsen, T. F.; Vaagen, J. S.

    1990-01-01

    After an unintended time gap of five years, the series of regular Nordic meetings on nuclear physics was continued with the 6th Nordic Meeting, August 10-15, 1989. The site was Utgarden in the outskirts of Kopervik, the administration center for the Saga island of Karmøy on the west-coast of Norway. Utgarden, a "peoples high-school'' with a kitchen, housing facility and a neighboring modern gymnasium with fine lecture halls, proved to be an inexpensive and adequate site for the meeting. From the time of the Vikings, the sound between Karmøyy and the mainland has been a vital part of the way to the north. Mobility and international orientation is still a signature of an area where today essential parts of Norway's oil- and metal industry are located. The conference program included a session on nuclear physics in industry and society, with contributed talks from a number of companies and technology/research institutions, which also sponsored the meeting. Lunch visits to Hydro's aluminium plant on Karmøy or alternatively to Statoil's gas terminal on the mainland, were included in the program. The scientific program gives a cross section of nuclear physics activities in which researchers from the Nordic countries are involved nowadays. The spectrum is rich, and the emphasis has shifted to higher energies than was the case five years ago. We appreciate the possibility to present this overview in a separate volume of Physica Scripta. The present issue covers nearly all the talks given at the meeting. The order deviates, however, somewhat from that of the conference program. The organizing committee tried to encourage in various ways the participation of young physicists; this effort was truely rewarded. The young participants put their imprint on the activities in the lecture halls and even more on the soccer arena. The meeting was sponsored by The University of Bergen, The Nordic Accelerator Committee, NORDITA, The Norwegian Research Council for Science and the

    2007-02-01

    Blood pressure screening was conducted on 4,311 (Hispanic n = 763 [17.7%], White n = 2,566 [59.5%], African American n = 610 [14.1%], Asian n = 136 [3.2%], Multiracial n = 231 [5.4%], and Native American n = 5 [0.1%]) 6th-grade students enrolled in Seminole County, Florida, Public Schools from August to December 2005. Prevalence of obesity was 21% for the overall population, with Hispanics n = 218 (28.6%) having a greater prevalence than non-Hispanics n = 630 (19.0%). Following a second screening, overall prevalence of elevated blood pressure was 1.9%, with Hispanics at 2.6% versus 1.6% for non-Hispanics. This was found to be significant when Hispanics were further compared to the White population. However, when adjusted for obesity, elevated blood pressure was not significant for Hispanics. Results confirm the presence of elevated blood pressure and obesity in all population groups, with an elevated risk for both among the Hispanic population.

  8. Perspectives on caring in the classroom: do they vary according to ethnicity or grade level?

    PubMed

    Garrett, Tracey; Barr, Jason; Rothman, Terri

    2009-01-01

    Research shows that students can articulate a definition of caring and identify specific behaviors of caring teachers. Some of this research also indicates that White students perceive caring differently from African American students. The purpose of this study was to examine what students from different cultural backgrounds and different grade levels identify as the practices teachers use to create a caring classroom. Sixth- and ninth-grade students from an ethnically diverse urban middle and high school completed a qualitative questionnaire on their teachers' classroom practices. Results indicate, although there were little differences in the categories and themes that emerged across ethnic groups and grade levels, when analyzing how the response percentages for each category were distributed within ethnic group and across grade levels, several differences were apparent.

    EPA Pesticide Factsheets

    A large number of environmental contaminants reduce circulating levels of thyroid hormone (TH), but clear markers of neurological insult associated with modest TH insufficiency are lacking. We have previously identified the presence of an abnormal cluster of misplaced neurons in the corpus callosum (CC), a heterotopia, in adult rats following hypothyroidism induced by the hormone synthesis inhibitor, propylthiouracil (PTU). In this report we have investigated the dose- response relationships to administered dose of PTU, the magnitude of reductions in circulating TH, and the incidence and volume of the heterotopia in adult offspring of PTU-treated dams. Pregnant rat dams were administered 0, 1, 2, 3 or 10 ppm of PTU in the drinking water from gestational day 6 until pups were weaned on postnatal day 21 (PN2 1). Serum hormones in the dams were reduced in a dose-dependent manner, but at the lower dose levels (1, 2 and 3ppm) reductions were limited to T4 with no change in serum T3. At higher PTU concentrations, serum T3 was reduced in dams (1 Oppm) and pups on PN14 and 21 (3 and 10 ppm). All hormone levels returned to control levels in adulthood. On PN 130, female offspring were perfused with paraformaldehyde and sections prepared for immunohistochemistry for the neuron-specific antibody NeuN. All sections (40-45 50u through the hippocampus) were examined for the presence of a heterotopia in the CC. A dose-dependent increase in incidence and volume of heterotopic re

  15. What predicts the selection of nursing as a career choice in 5th and 6th year school students?

    PubMed

    Neilson, Gavin R; Jones, Martyn C

    2012-07-01

    Demand for nursing care, and nurses, is growing in the United Kingdom given an increasingly ageing patient population with long-term co-morbidities. An ageing nursing workforce and fewer school leavers entering nursing are key barriers to student nurse recruitment. This paper aims to identify the socio-demographic and correlates nursing as a career choice in 5th and 6th year school students. This cross-sectional descriptive study gathered self-administered questionnaires from a total cohort of 5th and 6th year school students (n=1059) in one educational authority in Scotland. A response rate of 100% was achieved, with 702 students expressing a career choice. Some 71.7% (n=503) of students providing a full data set would never consider nursing, even if they obtained poor grades. Only 28.3% (n=199) would ever consider nursing. Students cited nursing as a career choice if they were female, of average to below average academic ability/achievement, expressed a positive attitude to nursing as a degree subject which was shared by their career guidance teacher. Each additional higher reduced the likelihood of nursing as a career choice by 22%. Nursing is an unpopular career choice amongst school students. Strategies are required to improve the occupational image of nursing in secondary education.

  16. Comparison of Different Methods of Grading a Level Turn Task on a Flight Simulator

    NASA Technical Reports Server (NTRS)

    Heath, Bruce E.; Crier, tomyka

    2003-01-01

    With the advancements in the computing power of personal computers, pc-based flight simulators and trainers have opened new avenues in the training of airplane pilots. It may be desirable to have the flight simulator make a quantitative evaluation of the progress of a pilot's training thereby reducing the physical requirement of the flight instructor who must, in turn, watch every flight. In an experiment, University students conducted six different flights, each consisting of two level turns. The flights were three minutes in duration. By evaluating videotapes, two certified flight instructors provided separate letter grades for each turn. These level turns were also evaluated using two other computer based grading methods. One method determined automated grades based on prescribed tolerances in bank angle, airspeed and altitude. The other method used was deviations in altitude and bank angle for performance index and performance grades.

  17. 1/6TH SCALE STRIP EFFLUENT FEED TANK-MIXING RESULTS USING MCU SOLVENT

    SciTech Connect

    Hansen, E

    2006-02-01

    The purpose of this task was to determine if mixing was an issue for the entrainment and dispersion of the Modular Caustic Side Solvent Extraction (CSSX) Unit (MCU) solvent in the Defense Waste Processing Facility (DWPF) Strip Effluent Feed Tank (SEFT). The MCU strip effluent stream containing the Cs removed during salt processing will be transferred to the DWPF for immobilization in HLW glass. In lab-scale DWPF chemical process cell testing, mixing of the solvent in the dilute nitric acid solution proved problematic, and the Savannah River National Laboratory (SRNL) was requested to perform scaled SEFT mixing tests to evaluate whether the problem was symptomatic of the lab-scale set-up or of the solvent. The solvent levels tested were 228 and 235 ppm, which represented levels near the estimated DWPF solvent limit of 239 ppm in 0.001M HNO{sub 3} solution. The 239 ppm limit was calculated by Norato in X-CLC-S-00141. The general approach for the mixing investigation was to: (1) Investigate the use of fluorescent dyes to aid in observing the mixing behavior. Evaluate and compare the physical properties of the fluorescent dyed MCU solvents to the baseline Oak Ridge CSSX solvent. Based on the data, use the dyed MCU solvent that best approximates the physical properties. (2) Use approximately a 1/6th linear scale of the SEFT to replicate the internal configuration for DWPF mixing. (3) Determine agitator speed(s) for scaled testing based on the DWPF SEFT mixing speed. (4) Perform mixing tests using the 1/6th SEFT and determine any mixing issues (entrainment/dispersion, accumulation, adhesion) through visual observations and by pulling samples to assess uniformity. The mixing tests used MCU solvent fabricated at SRNL blended with Risk Reactor DFSB-K43 fluorescent dye. This dyed SRNL MCU solvent had equivalent physical properties important to mixing as compared to the Oak Ridge baseline solvent, blended easily with the MCU solvent, and provided an excellent visual aid.

  1. Predictors of cultural capital on science academic achievement at the 8th grade level

    NASA Astrophysics Data System (ADS)

    Misner, Johnathan Scott

    The purpose of the study was to determine if students' cultural capital is a significant predictor of 8th grade science achievement test scores in urban locales. Cultural capital refers to the knowledge used and gained by the dominant class, which allows social and economic mobility. Cultural capital variables include magazines at home and parental education level. Other variables analyzed include socioeconomic status (SES), gender, and English language learners (ELL). This non-experimental study analyzed the results of the 2011 Eighth Grade Science National Assessment of Educational Progress (NAEP). The researcher analyzed the data using a multivariate stepwise regression analysis. The researcher concluded that the addition of cultural capital factors significantly increased the predictive power of the model where magazines in home, gender, student classified as ELL, parental education level, and SES were the independent variables and science achievement was the dependent variable. For alpha=0.05, the overall test for the model produced a R2 value of 0.232; therefore the model predicted 23.2% of variance in science achievement results. Other major findings include: higher measures of home resources predicted higher 2011 NAEP eighth grade science achievement; males were predicted to have higher 2011 NAEP 8 th grade science achievement; classified ELL students were predicted to score lower on the NAEP eight grade science achievement; higher parent education predicted higher NAEP eighth grade science achievement; lower measures of SES predicted lower 2011 NAEP eighth grade science achievement. This study contributed to the research in this field by identifying cultural capital factors that have been found to have statistical significance on predicting eighth grade science achievement results, which can lead to strategies to help improve science academic achievement among underserved populations.

  2. Higher Grades and Repeated Recurrence of Hepatic Encephalopathy May Be Related to High Serum Manganese Levels.

    Kobtan, Abdelrahman A; El-Kalla, Ferial S; Soliman, Hanan H; Zakaria, Soha S; Goda, Mohamed A

    2016-02-01

    Hepatic encephalopathy is a serious complication of liver failure. Until now, the precise pathophysiologic mechanisms are not fully determined. It has been demonstrated that manganese plays an important role in the pathogenesis of hepatic encephalopathy. Therefore, we studied manganese levels in serum of cirrhotic patients with hepatic encephalopathy in relation to grading and recurrence of hepatic encephalopathy. One hundred persons were enrolled in the study, 80 cirrhotic patients with or without encephalopathy and 20 healthy controls. Hepatic encephalopathy was diagnosed clinically and by laboratory findings. Serum manganese levels were measured in all participants. The grading of hepatic encephalopathy was significantly correlated to the severity of liver dysfunction. The mean serum manganese level was significantly higher in cirrhotic patients than in controls and in cirrhotic patients with encephalopathy than in those without encephalopathy. It was also significantly higher in patients with advanced grading of hepatic encephalopathy. Serum manganese level was positively correlated to number of recurrences of encephalopathy during a 6-month follow-up period. Serum manganese levels were able to predict recurrence of hepatic encephalopathy within 6 months following the episode. Serum manganese levels are positively correlated to the modified Child-Pugh score of cirrhosis as well as grading and number of recurrences of hepatic encephalopathy. Higher manganese levels seem to be related to worsening of the condition, and its measurement may be used as a predictor of repeated recurrences.

  3. Theory of Landau level mixing in heavily graded graphene p -n junctions

    LaGasse, Samuel W.; Lee, Ji Ung

    2016-10-01

    We demonstrate the use of a quantum transport model to study heavily graded graphene p -n junctions in the quantum Hall regime. A combination of p -n interface roughness and delta function disorder potential allows us to compare experimental results on different devices from the literature. We find that wide p -n junctions suppress mixing of n ≠0 Landau levels. Our simulations spatially resolve carrier transport in the device, revealing separation of higher order Landau levels in strongly graded junctions, which suppresses mixing.

    2004-02-01

    This article presents MANULEX, a Web-accessible database that provides grade-level word frequency lists of nonlemmatized and lemmatized words (48,886 and 23,812 entries, respectively) computed from the 1.9 million words taken from 54 French elementary school readers. Word frequencies are provided for four levels: first grade (G1), second grade (G2), third to fifth grades (G3-5), and all grades (G1-5). The frequencies were computed following the methods described by Carroll, Davies, and Richman (1971) and Zeno, Ivenz, Millard, and Duvvuri (1995), with four statistics at each level (F, overall word frequency; D, index of dispersion across the selected readers; U, estimated frequency per million words; and SFI, standard frequency index). The database also provides the number of letters in the word and syntactic category information. MANULEX is intended to be a useful tool for studying language development through the selection of stimuli based on precise frequency norms. Researchers in artificial intelligence can also use it as a source of information on natural language processing to simulate written language acquisition in children. Finally, it may serve an educational purpose by providing basic vocabulary lists.

  8. Factors in seventh grade academics associated with performance levels on the tenth grade biology end of course test in selected middle and high schools in northwest Georgia

    NASA Astrophysics Data System (ADS)

    Ward, Jennifer Henry

    This study attempted to identify factors in seventh grade academics that are associated with overall success in tenth grade biology. The study addressed the following research questions: Are there significant differences in performance levels in seventh grade Criterion Referenced Competency Test (CRCT) scores in science, math, reading, and language arts associated with performance categories in tenth grade biology End of Course Test (EOCT) and the following demographic variables : gender, ethnicity, socioeconomic status, disability category, and English language proficiency level? Is there a relationship among the categorical variables on the tenth grade biology EOCT and the same five demographic variables? Retrospective causal comparative research was used on a representative sample from the middle schools in three North Georgia counties who took the four CRCTs in the 2006-2007 school year, and took the biology EOCT in the 2009-2010 school year. Chi square was used to determine the relationships of the various demographic variables on three biology EOCT performance categories. Twoway ANOVA determined relationships between the seventh grade CRCT scores of students in the various demographic groups and their performance levels on the biology EOCT. Students' performance levels on the biology EOCT matched their performance levels on the seventh grade CRCTs consistently. Females performed better than males on all seventh grade CRCTs. Black and Hispanic students did worse than White and Asian/Asian Indian students on the math CRCT. Students living in poverty did worse on reading and language arts CRCTs than students who were better off. Special education students did worse on science, reading, and language arts CRCTs than students not receiving special education services. English language learners did worse than native English speakers on all seventh grade CRCTs. These findings suggest that remedial measures may be taken in the seventh grade that could impact

    2014-04-01

    Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers' responses to a questionnaire were adopted to identify the factors influencing teacher's enactment. The results indicate that the two case teachers' enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements "making plans" to solve problems in authentic context. Important factors influencing the enactment include teacher's understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided.

    The present study was conducted to evaluate the level of food safety protection provided to consumers of Grade "A" milk and milk products in the United States by the National Conference on Interstate Milk Shipments (NCIMS) Grade "A" Milk Safety Program through its implementation and enforcement of the U.S. Grade "A" Pasteurized Milk Ordinance (PMO). The number of reported illnesses associated with Grade "A" milk and milk products in the United States was obtained from state and federal agencies and published articles. The consumption of Grade "A" milk and milk products in the United States was estimated from food consumption survey data for individuals. The level of food safety protection was measured quantitatively using the metric of annual illness attack rate. During a 15-year period (1999 through 2013), the estimated annual illness attack rate was 0.41 reported illnesses per 1 billion exposures (estimated using person-day intake data) or 0.52 reported illnesses per 1 billion lb (454 million kg) of Grade "A" milk and milk products consumed. Food safety protection provided to consumers of Grade "A" milk and milk products by the NCIMS through its implementation and enforcement of the PMO is important given the common consumption of Grade "A" milk and milk products in the United States.

    This volume of Journal of Physics: Conference Series is dedicated to a subset of papers related to the work presented at the 6th edition of the international Workshop on Infrared Spectroscopy and Microscopy with Accelerator-Based Sources (WIRMS), held in Trieste, Italy, September 4-8 2011. Previous editions of the conference were held in Porquerolles (France), Lake Tahoe (USA), Rathen (Germany), Awaji (Japan), and Banff (Canada). This edition was organized and chaired by Stefano Lupi (Roma La Sapienza) and co-chaired by Andrea Perucchi (Elettra), with the support of the Italian Synchrotron Light Laboratory ELETTRA, which was honored to host the WIRMS workshop in its tenth anniversary. The 6th WIRMS edition addressed several different topics, ranging from biochemistry to strongly correlated materials, from geology to conservation science, and from forensics to the study of cometary dusts. Representatives from the infrared scientific programs at synchrotron light sources and free-electron-laser facilities. This edition was attended by 88 participants, including representatives from the infrared scientific programs at synchrotron light sources and free-electron-laser facilities, who enjoyed the stimulating scientific presentations, several detailed discussions, and the beautiful weather and scenery of the Trieste gulf. Participants came from 16 different nations and four continents, including many young scientists, six of which were supported by the organizers. There were 45 scientific talks divided in 11 sessions: Facilities, Microspectroscopy (I, II, III), Time-Resolved Spectroscopies, Extreme Conditions, Condensed Matter, Near-Field, Imaging, THz Techniques and High-Resolution Spectroscopy. 37 posters were also presented at two very lively evening poster sessions. We would like to use the opportunity of writing this preface to thank all the participants of the workshop for the very high level of their scientific contribution and for the very friendly atmosphere

    Background Epidemiological data suggest that omega-6 (ω-6) fatty acids (FAs) may be associated with cancer incidence and/or cancer mortality, whereas ω-3 FAs are potentially protective. We examined the association of the ratio of ω-6 to ω-3 FA (ω-6:ω-3) and individual FA components with pathological results among men with prostate cancer (PCa) undergoing radical prostatectomy. Methods Sixty-nine men were included in the study. Components of ω-6 (linoleic acid (LA), arachidonic acid (AA), and dihomo-γ-linolenic acid (DGLA)) and ω-3 (docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)) were analyzed by liquid chromatography/mass selective detector separation. Logistic regression analysis was performed to determine association of FA with pathological high grade (Gleason ≥4+3) disease. Results The were 35 men with low grade disease (Gleason ≤3+4) and 34 men with high grade disease. Men with low grade disease were significantly younger (58y vs 61y, p = 0.012) and had lower D’Amico clinical classification (p = 0.001) compared to men with high grade disease. There was no significant association of ω-6:ω-3 with high grade disease (OR 0.93, p = 0.78), however overall ω-6, ω-3, and individual components of ω-6 and ω-3 FAs except EPA were significantly associated with high grade disease (ω-6: OR 3.37, 95% CI: 1.27,8.98; LA: OR 3.33, 95% CI:1.24,8.94; AA: OR 2.93, 95% CI:1.24,6.94; DGLA: OR 3.21, 95% CI:1.28,8.04; ω-3: OR 3.47, 95% CI:1.22,9.83; DHA: OR 3.13, 95% CI:1.26,7.74). ω-6 and ω-3 FA components were highly correlated (Spearman ρ = 0.77). Conclusion Higher levels of individual components of ω-6 and ω-3FAs may be associated with higher-grade PCa. Impact Studies into the causative factors/pathways regarding FAs and prostate carcinogenesis may prove a potential association with PCa aggressiveness. PMID:27880795

    Prostate cancer (PC) is a leading male oncologic malignancy wideworld. During malignant transformation, normal epithelial cells undergo genetic and morphological changes known as epithelial-mesenchymal transition (EMT). Several regulatory genes and specific marker proteins are involved in PC EMT. Recently, syndecans have been associated with malignancy grade and Gleason score in PC. Considering that SNAIL is mainly a gene repressor increased in PC and that syndecan promoters have putative binding sites for this repressor, we propose that SNAIL might regulate syndecan expression during PC EMT. The aim of this study was to analyze immunochemically the expression of SNAIL, syndecans 1 and 2 and other EMT markers in a tissue microarray (TMA) of PC samples and PC cell lines. The TMAs included PC samples of different Gleason grade and benign prostatic hyperplasia (BPH) samples, as non-malignant controls. PC3 and LNCaP cell lines were used as models of PC representing different tumorigenic capacities. Semi-quantitative immunohistochemistry was performed on TMAs and fluorescence immunocytochemistry and western blot analysis were conducted on cell cultures. Results show that SNAIL exhibits increased expression in high Gleason specimens compared to low histological grade and BPH samples. Accordingly, PC3 cells show higher SNAIL expression levels compared to LNCaP cells. Conversely, syndecan 1, similarly to E-cadherin (a known marker of EMT), shows a decreased expression in high Gleason grades samples and PC3 cells. Interestingly, syndecan 2 shows no changes associated to histological grade. It is concluded that increased SNAIL levels in advanced PC are associated with low expression of syndecan 1. The mechanism by which SNAIL regulates the expression of syndecan 1 remains to be investigated. PMID:24424718

  16. Recurrent 6th nerve palsy in a child following different live attenuated vaccines: case report

    PubMed Central

    2012-01-01

    Background Recurrent benign 6th nerve palsy in the paediatric age group is uncommon, but has been described following viral and bacterial infections. It has also been temporally associated with immunization, but has not been previously described following two different live attenuated vaccines. Case presentation A case is presented of a 12 month old Caucasian boy with recurrent benign 6th nerve palsy following measles-mumps-rubella and varicella vaccines, given on separate occasions with complete recovery following each episode. No alternate underlying etiology was identified despite extensive investigations and review. Conclusions The majority of benign 6th nerve palsies do not have a sinister cause and have an excellent prognosis, with recovery expected in most cases. The exact pathophysiology is unknown, although hypotheses including autoimmune mechanisms and direct viral invasion could explain the pathophysiology behind immunization related nerve palsies. It is important to rule out other aetiologies with thorough history, physical examination and investigations. There is limited information in the literature regarding the safety of a repeat dose of a live vaccine in this setting. Future immunizations should be considered on a case-by-case basis.

    There are multiple proposals and classifications that hierarchize evidence, which may confuse those who are dedicated to generate it both in health technology assessments, as for the development of clinical guidelines, etc. The aim of this manuscript is to describe the most commonly used classifications of levels of evidence and grades of recommendation, analyzing their main differences and applications so that the user can choose the one that better suits your needs and take this health decisions basing their practice on the best available evidence. A systematic literature search was performed in PubMed and MEDLINE databases and in Google, Yahoo and Ixquick search engines. A wealth of information concerning levels of evidence and degrees recommendation was obtained. It was summarized the information of the 11 proposals more currently used (CTFPHC, Sackett, USPSTF, CEBM, GRADE, SIGN, NICE, NHMRC, PCCRP, ADA y ACCF/AHA), between which it emphasizes the GRADE WORKING GROUP, incorporated by around 90 national and international organizations such as the World Health Organization, The Cochrane Library, American College of Physicians, American Thoracic Society, UpToDate, etc.; and locally by the Ministry of Health to create clinical practice guidelines.

  18. Students' Attitudes Toward Chemistry Lessons: The Interaction Effect between Grade Level and Gender

    2009-01-01

    The purpose of this quantitative study was to examine the interaction effect between grade level and gender with respect to students' attitudes toward chemistry lessons taught in secondary schools. The sample consisted of 954 chemistry students in grades Secondary 4-7 (approximately 16-19 years of age) in Hong Kong. Students' attitudes were surveyed using an attitude toward chemistry lessons scale (ATCLS), and subscale scores were produced on four dimensions: liking for chemistry theory lessons; liking for chemistry laboratory work; evaluative beliefs about school chemistry; and behavioral tendencies to learn chemistry. When the ATCLS data were subjected to two-way MANOVA, the interaction effect between grade level and gender on students' attitudes toward chemistry lessons was statistically significant. The interaction effect was attributable to scores on the theory lessons subscale and laboratory work subscale. Male students in Secondary 4 and 5 liked chemistry theory lessons more than their female counterparts. However, male students' liking for chemistry laboratory work declined when they progressed from Secondary 4 to Secondary 7; no such a significant decline in attitude toward chemistry laboratory work was found in females. Overall, both males and females were just marginally positive about chemistry lessons during the years of secondary schooling. Implications of these findings for curriculum design are discussed.

  19. Effects of multisensory resources on the achievement and science attitudes of seventh-grade suburban students taught science concepts on and above grade level

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

    The germ of an analytic variety X at a point x∈ X is said to be quadratic if it is bi-analytically isomorphic to the germ of a cone defined by a system of homogeneous quadratic equations at the origin. Arms, Marsden and Moncrief show in [2] that under certain conditions the analytic germ of a level set of a momentum mapping is quadratic. We discuss related ideas in a more algebraic context by associating to an affine Hamiltonian action a differential graded Lie algebra, which in the presence of an invariant positive complex structure, is formal in the sence of [5].

    Objective The intensive nature of a 5- or 6-week teaching block poses unique problems for adequate delivery of content. This study was designed to compare the delivery of a unit of undergraduate neuroanatomy in a short summer school period, as a traditionally taught unit, with a rendition given in the form of the “Flipped Classroom.” The aim was to evaluate the effectiveness of the flipped classroom in the intensive mode classroom. Methods The flipped classroom encompassed the same learning outcomes, but students were responsible for covering the content at home in preparation for tutorials that applied their acquired knowledge to higher levels of thinking. The main outcome measures were the final course grades and the level of satisfaction with the course. Results There were no significant differences between the 2 cohorts in final grades (p = .259), self-rated knowledge (p = .182), or overall satisfaction with the course (p = .892). Conclusion This particular design of the flipped classroom did not add value to the intensive mode experience. It may be that this mode of delivery is ill suited to intensive classes for subjects that carry a lot of content. The use of the flipped classroom requires further research to fully evaluate its value. PMID:25902472

    Evaluation of bone mineral density (BMD) of the ancient peoples has received great interest by anthropologists. The aims of this study are to investigate the lumbar vertebrae of the Iasos people during the Byzantine period, in order to determine the prevalence of bone loss and to interpret dietary conditions of ancient Mediterranean populations. Lumbar vertebrae belonging to twenty eight skeletons of the 6th c AD were analyzed by radiographs and dual energy X-ray absorptiometry. The BMD values for each biologic sex and age group were compared. The correlation between the BMD and radiological features was also analyzed. The mean BMD was 0.940 g/cm2. BMD was decreased by aging in both sexes, but it was not significant. Osteopenia was found in 11 (39%) and osteoporosis in 4 (14.3%) out 28 vertebrae. The BMD was normal in 13 (46%) out of 28 vertebrae. Osteopenia was present in 7 (38%) of 18 male vertebrae and 4 (40%) of 10 female vertebrae. The spine score was high in the male group and there was a strong positive correlation between the BMD and spine score for both sexes. This study revealed that the BMD decreased by aging and that osteopenia was a problem in both sexes of the Iasos people during the 6th c AD. There was no correlation between the BMD and radiological features for age groups and biological sexes.

    Explanations involving submicro levels of representation are central to science education, but known to be difficult for students in secondary school. This study examines students' written explanations of physical and chemical phenomena regarding matter and changes in matter, in a large-scale test. This is done in order to understand linguistic challenges in constructing submicro level explanations involving the particle model of matter. Drawing from systemic functional linguistics, the lexicogrammatics used in explanations for realising experiential meaning in student explanations were analysed. We used answers to two partly constructed response items from the Swedish part of Trends in International Mathematics and Science Studies 2007, grade 8, to sort out explanations referring to the particle model of matter. These answers (86 from 954) were analysed regarding choices of vocabulary and grammar to distinguish between macro and submicro level of representation. The results show that students use a wide variety of lexicogrammatical resources to realise what happens on both macro and submicro level of representation, with greater diversity of verbs on the submicro level of explanation. The results suggest an uncertainty about the distinction between macro and submicro level of explanation.

    Mountain endurance running has increased in popularity in recent years. Thus the aim of the present study was to determine if maximal oxygen uptake (VO2max) and energy cost of running (Cr) measured during level and uphill running are associated. Ten high level male endurance mountain runners performed three maximal oxygen uptake tests at three slope conditions (0, 12.5 and 25%). Metabolic data, step frequency (SF) and step length (SL) were recorded. No significant differences were found in VO2max (63.29 (±3.84), 63.97 (±3.54) and 63.70 (±3.58) mlO2/kg(-1)/min(-1)) or associated metabolic data at 0, 12.5 and 25% slope respectively. High intra-individual correlations were found between metabolic data measured in the three conditions. The energy cost of running was significantly different between slopes (0.192 (±0.01), 0.350 (±0.029) and 0.516 (±0.035) mlO2/kg(-1)/min(-1), p < 0.01), 0, 12.5 and 25% respectively. However, Cr0% was not correlated with either Cr25% or Cr12.5% (rs = 0.09 and rs = 0.10), in contrast, Cr25% and Cr12.5% were correlated (rs = 0.78). Step length was positively correlated with speed under the three slope conditions. Step frequency was significantly lower at 25 compared to 12.5 and 0% slope. We found that the maximum aerobic power did not differ between level and graded treadmill tests. However, the increase in Cr on the inclined versus level conditions varied between subjects. None of the measured anthropometric or kinematic variables could explain the higher increase in Cr of some subjects when running uphill. Thus, a short graded (5min at 12.5%) running test should be performed at a submaximal velocity (around 40% of level vVO2max) to enhance understanding of an endurance runner's uphill capability. Key pointsIn elite endurance mountain runners, there is no difference in VO2max values between level and uphill running.In a homogeneous group of mountain runners, uphill Cr is not associated with level Cr.To assess performance potential of

    The present meta-analysis examined the effect of grade retention on academic outcomes and investigated systemic sources of variability in effect sizes. Using multi-level modeling, we investigated characteristics of 207 effect sizes across 22 studies published between 1990 and 2007 at two levels: the study (between) and individual (within) levels. Design quality was a study-level variable. Individual level variables were median grade retained and median number of years post retention. Quality of design was associated with less negative effects. Studies employing middle to high methodological designs yielded effect sizes not statistically significantly different from zero and 0.34 higher (more positive) than studies with low design quality. Years post retention was negatively associated with retention effects, and this effect was stronger for studies using grade comparisons versus age comparisons. Results challenge the widely held view that retention has a negative impact on achievement. Suggestions for future research are discussed. PMID:20717492

  4. An integrated exploration model for Council Run field analogs: Regional geology and seismic stratigraphy of Devonian 6th Elk sandstones

    1991-08-01

    A geologic study of the Devonian Lock Haven 6th Elk formation along the structural front of Pennsylvania and Maryland suggest that present-day structures were active at the time of deposition. These structures barred deposition to the west and helped to localize sands in a northeast-southwest fairway. The 6th Elk sandstones occur in two major depositional lobes (located in Centre and Somerset counties in Pennsylvania, and Garret County, Maryland) and were deposited on a shallow-marine shelf by turbidity currents and later modified by storm-generated currents. Deposition of 6th Elk sands may also have been influenced by cross-strike discontinuities. A seismic study of the Council Run field aids in subsurface identification of the 6th Elk. A high-amplitude seismic anomaly across the Council Run field is correlated with increasing san thickness. Two dimensional modeling suggests that the seismic response is extremely sensitive to specific acquisition and processing techniques including filter and phase variability. Additional attribute analysis integrates the seismic data with the forward models. This results in a predictive method for potentially identifying 6th Elk sandstone development from seismic data. Applying the results of the seismic modeling at Council Run field to a seismic grid across the previously defined 6th Elk depositional fairway has identified many exploratory prospects in Lycoming and Bradford counties, Pennsylvania. This area coincides with the site of a third, previously documented, Upper Devonian depositional lobe.

    Monitoring of chemical and physical groundwater parameters has been carried out worldwide in seismogenic areas with the aim to test possible correlations between their spatial and temporal variations and strain processes. Uranium (U) groundwater anomalies were observed during the preparation phases of the recent L'Aquila earthquake of 6th April 2009 in the cataclastic rocks near the overthrust fault crossing the deep underground Gran Sasso National Laboratory. The results suggest that U may be used as a potential strain indicator of geodynamic processes occurring before the seismic swarm and the main earthquake shock. Moreover, this justifies the different radon patterns before and after the main shock: the radon releases during and after the earthquake are much than more during the preparatory period because the process does not include only the microfracturing induced by stress-strain activation, but also radon increases accompanying groundwater U anomalies.

    A graphical framework is used for statistical analysis of the results from an extensive N- version test of a collection of Reynolds-averaged Navier-Stokes computational uid dynam- ics codes. The solutions were obtained by code developers and users from North America, Europe, Asia, and South America using both common and custom grid sequencees as well as multiple turbulence models for the June 2016 6th AIAA CFD Drag Prediction Workshop sponsored by the AIAA Applied Aerodynamics Technical Committee. The aerodynamic con guration for this workshop was the Common Research Model subsonic transport wing- body previously used for both the 4th and 5th Drag Prediction Workshops. This work continues the statistical analysis begun in the earlier workshops and compares the results from the grid convergence study of the most recent workshop with previous workshops.

  7. Rapid landscape change in 6th century northern Jordan: interdisciplinary geoarchaeological perspectives

    NASA Astrophysics Data System (ADS)

    Lucke, Bernhard

    2016-04-01

    Landscapes of the ancient fertile crescent are considered affected by soil degradation as result of long-term farming since the Neolithic, and impressive ruins of antiquity led to assumptions that their abandonment must have been conntected with reduced agricultural productivity. In this context, a valley fill near the site of Abila of the Decapolis in northern Jordan was apparently deposited largely during the 6th century AD, and provides evidence for a rapid and intense landscape change during the Late Byzantine period. However, an interdisciplinary case study of land use, soil development, and sediments found that the valley fill cannot be connected with large-scale soil erosion in the vicinity of the site. On the one hand, this is indicated by the distribution of soil development and archaeological material as marker of past land use activity in the past, which suggests that the best soils were and still are used intensively. On the other hand, the sediments seem to point to the occurrence of climatic extremes such as heavy floods, the occurrence of soil creep after water saturation, but also a significant shift to aridity which may have triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, possibly connected with the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. Modern analogies of the Pinatubo eruption in 1991 let it seem possible that a volcanic event, perhaps the outbreak of the Ilopango volcano, was connected with these environmental turbulences. Such events cannot be understood by isolated studies: without a broad interdisciplinary framework, single archives are prone to misinterpretation, and our understanding of the environmental history of Abila is still very limited.

    The aim of this study was to investigate the effects of graded levels of montmorillonite, a constituent of clay, on performance, hematological parameters and bone mineralization in weaned pigs. One hundred and twenty, 35-d-old crossbred pigs (Duroc×Large White×Landrace, 10.50±1.20 kg) were used in a 28-d experiment and fed either an unsupplemented corn-soybean meal basal diet or similar diets supplemented with 0.5, 1.0, 2.5 or 5.0% montmorillonite added at the expense of wheat bran. Each treatment was replicated six times with four pigs (two barrows and two gilts) per replicate. Feed intake declined (linear and quadratic effect, p< 0.01) with increasing level of montmorillonite while feed conversion was improved (linear and quadratic effect, p<0.01). Daily gain was unaffected by dietary treatment. Plasma myeloperoxidase declined linearly (p = 0.03) with increasing dietary level of montmorillonite. Plasma malondialdehyde and nitric oxide levels were quadratically affected (p<0.01) by montmorillonite with increases observed for pigs fed the 0.5 and 1.0% levels which then declined for pigs fed the 2.5 and 5.0% treatments. In bone, the content of potassium, sodium, copper, iron, manganese and magnesium were decreased (linear and quadratic effect, p<0.01) in response to an increase of dietary montmorillonite. These results suggest that dietary inclusion of montmorillonite at levels as high as 5.0% does not result in overt toxicity but could induce potential oxidative damage and reduce bone mineralization in pigs.

    Food intake and circadian rhythms are regulated by hypothalamic neuropeptides and circulating hormones, which could mediate the anti‐ageing effect of calorie restriction (CR). We tested whether these two signaling pathways mediate CR by quantifying hypothalamic transcripts of male C57BL/6 mice exposed to graded levels of CR (10 % to 40 %) for 3 months. We found that the graded CR manipulation resulted in upregulation of core circadian rhythm genes, which correlated negatively with circulating levels of leptin, insulin‐like growth factor 1 (IGF‐1), insulin, and tumor necrosis factor alpha (TNF‐α). In addition, key components in the hunger signaling pathway were expressed in a manner reflecting elevated hunger at greater levels of restriction, and which also correlated negatively with circulating levels of insulin, TNF‐α, leptin and IGF‐1. Lastly, phenotypes, such as food anticipatory activity and body temperature, were associated with expression levels of both hunger genes and core clock genes. Our results suggest modulation of the hunger and circadian signaling pathways in response to altered levels of circulating hormones, that are themselves downstream of morphological changes resulting from CR treatment, may be important elements in the response to CR, driving some of the key phenotypic outcomes.

    The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consumption, and gain-to-feed ratio increased (P < 0.01) as O2 concentration incrementally rose from 12 to 20.6%. Body weight was 138 g for the lowest atmospheric O2 level compared to 371 g for 20.6% O2. The greatest treatment difference occurred between the 12 and 14% O2 concentrations. Growth depression appeared related to feed consumption. Ascites heart ratio (AHR), ascites score (AS), right ventricular mass (RVM), and hematocrit (HCT) all increased (P < 0.01) as O2 concentration decreased. Blood HCT appeared to be a more sensitive indicator of physiological change attributable to atmospheric O2 than AHR, AS, or RVM. The data reported herein suggests that 19.6% atmospheric O2 is the minimal allowable level for housing birds within a relatively stress-free, TN environment to avoid cardiac and HCT changes related to ascites.

    Groups of Grade 3 children were tested on measures of word-level literacy and undertook tasks that required the ability to associate sounds with letter sequences and that involved visual, auditory and phonological-processing skills. These groups came from different language backgrounds in which the language of instruction was Arabic, Chinese, English, Hungarian or Portuguese. Similar measures were used across the groups, with tests being adapted to be appropriate for the language of the children. Findings indicated that measures of decoding and phonological-processing skills were good predictors of word reading and spelling among Arabic- and English-speaking children, but were less able to predict variability in these same early literacy skills among Chinese- and Hungarian-speaking children, and were better at predicting variability in Portuguese word reading than spelling. Results were discussed with reference to the relative transparency of the script and issues of dyslexia assessment across languages. Overall, the findings argue for the need to take account of features of the orthography used to represent a language when developing assessment procedures for a particular language and that assessment of word-level literacy skills and a phonological perspective of dyslexia may not be universally applicable across all language contexts.

    Lipid peroxidation, protein oxidation and antioxidant activities of muscle, intestine, hepatopancreas and serum in juvenile Jian carp (Cyprinus carpio var. Jian) were investigated after feeding graded levels of biotin (0.010, 0.028, 0.054, 0.151, 0.330, 1.540 and 2.680 mg kg(-1) diet) for 63 days. Both malondialdehyde and protein carbonyl content in all studied tissues and serum were the lowest in fish fed diets containing 0.151-0.330 mg biotin kg(-1) diet and then increased in fish fed the diet with 2.680 mg biotin kg(-1) diet (P < 0.05). Similarly, glutamate-oxaloacetate transaminase and glutamate-pyruvate transaminase activities in serum significantly decreased with biotin levels up to 0.151 mg kg(-1) diet (P < 0.05). Conversely, capacities of anti-hydroxyl radical (AHR) and anti-superoxide anion (ASA) in the detected tissues and serum significantly improved with biotin levels up to 0.054-1.540 mg kg(-1) diet and then decreased in 2.680 mg biotin kg(-1) diet group for muscle and intestinal AHR as well as hepatopancreas ASA (P < 0.05). Activities of superoxide dismutase in all studied tissues and serum significantly elevated with biotin levels up to 0.330 mg kg(-1) diet and then decreased when fish fed the diet with 2.680 mg biotin kg(-1) diet, except intestine (P < 0.05). Meanwhile, activities of catalase, glutathione peroxidase, glutathione-S-transferase and glutathione reductase and total thiol content in all studied tissues and serum showed the upward trend with biotin supplementations (P < 0.05). These results indicated that biotin improved antioxidant status and depressed lipid peroxidation and protein oxidation in all studied tissues and serum.

    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 CaCO3) and Fe (existing as Fe2O3), 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.

    The purpose of this study was to examine the relationship between the snack intake and snack availability of elementary school children. Data analyzed were from 722 4th to 6th graders' food availability and food intake questionnaires collected in the Nutrition and Health Survey in Taiwan Elementary School Children 2001-2002. The snacks commonly eaten were divided into two groups. Healthy snacks included dairy products, 100% fruit juice and fresh fruits. Unhealthy snacks included high fat/sugar snacks, cookies, candy, carbonated/sugared beverages and fast food. Structural equating modeling was used to test the models that describe the availability and intake of two snack groups. Results indicated that parents' intake and children's preference were major predictors of children intake of both healthy and unhealthy snacks. Other than that, the intake of unhealthy snacks was positively associated with "purchase by children themselves" but not the intake of healthy snacks, which was influenced predominantly by "present in home". The results support the perception that a positive family food environment is important for improving children's diet quality. To build a healthy family food environment, parents have to not only provide healthy snacks but also limit the unhealthy snacks in home. In addition to that, the role modeling of parents as eating healthy snacks instead of unhealthy snacks themselves may help children to develop similar behaviors.

    Cancer is primarily an "old-age" disease that has an "age-old" history. The overall incidence of cancer is much higher in Western countries, but is rapidly growing in Eastern countries perhaps due to change in life-style. Almost three million studies published to date indicate that cancer is a hyperproliferative disorder that arises from dysregulation of multiple cell signaling pathways. The cancer genome landscape indicates that approximately 140 genes and 12 cell signaling pathways drive almost all cancers. "Targeted therapy," a buzz word in cancer treatment for the past two decades, has provided antibodies, as well as small-molecule inhibitors. These therapies have been successful only in few instances. However, in most cases, minor increase in overall survival has been reported at the cost of huge expense. An alternative strategy is to prevent cancer or to diagnose and treat the disease at an early stage to gain survival benefits. Such interventions are also cost-effective. To address some of these issues, the 6th International Translational Cancer Research Conference was held during February 4-7th, 2016, in Ahmedabad, Gujarat, India; the homeland of Mahatma Gandhi. This conference was focused on utilizing multidisciplinary approaches for prevention and early treatment that would likely simultaneously or sequentially target many key pathways. Several distinguished speakers were invited from around the world. This article highlights primary features of this conference.

    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.

    The 6th International Symposium on Electron Beam Ion sources and their Applications was held at the Manne Siegbahn Laboratory at Stockholm University, June 20-23, 1994. A symposium in this series is held every three years. The next one will be organised by Professor Reinhard Becker at the J. W. Goethe University in Frankfurt am Main, Germany. The Stockholm symposium had a total of 65 participants from 9 countries. 43 oral presentations were given and 7 posters were exhibited. For the first time in this series the proceedings have been refereed. The symposium was given generous support by the Marcus Wallbenberg Foundation for International Co-operation in Science, a support mainly used for inviting delegates from Russia and students. The organisation of the symposium was led by Dr. Carl Johan Herrlander. His efficiency, organising skill and never ending attention to all the aspects of the symposium were of the utmost importance for carrying it through. We deeply regret that the proceedings have been very much delayed. Physica Scripta has no part in causing the delay which is solely a result of my inability to enforce deadlines. We think though that the contents still is of interest in particular as a full documentation of the conference.

  4. PREFACE: 6th International Workshop on Pseudo-Hermitian Hamiltonians in Quantum Physics

    NASA Astrophysics Data System (ADS)

    Fring, Andreas; Jones, Hugh; Znojil, Miloslav

    2008-06-01

    Attempts to understand the quantum mechanics of non-Hermitian Hamiltonian systems can be traced back to the early days, one example being Heisenberg's endeavour to formulate a consistent model involving an indefinite metric. Over the years non-Hermitian Hamiltonians whose spectra were believed to be real have appeared from time to time in the literature, for instance in the study of strong interactions at high energies via Regge models, in condensed matter physics in the context of the XXZ-spin chain, in interacting boson models in nuclear physics, in integrable quantum field theories as Toda field theories with complex coupling constants, and also very recently in a field theoretical scenario in the quantization procedure of strings on an AdS5 x S5 background. Concrete experimental realizations of these types of systems in the form of optical lattices have been proposed in 2007. In the area of mathematical physics similar non-systematic results appeared sporadically over the years. However, intensive and more systematic investigation of these types of non- Hermitian Hamiltonians with real eigenvalue spectra only began about ten years ago, when the surprising discovery was made that a large class of one-particle systems perturbed by a simple non-Hermitian potential term possesses a real energy spectrum. Since then regular international workshops devoted to this theme have taken place. This special issue is centred around the 6th International Workshop on Pseudo-Hermitian Hamiltonians in Quantum Physics held in July 2007 at City University London. All the contributions contain significant new results or alternatively provide a survey of the state of the art of the subject or a critical assessment of the present understanding of the topic and a discussion of open problems. Original contributions from non-participants were also invited. Meanwhile many interesting results have been obtained and consensus has been reached on various central conceptual issues in the

    This study was conducted to understand the effect of student-, classroom-, and school-level factors on the science performance of 8th-grade Taiwanese students in the Trends in International Mathematics and Science Study (TIMSS) 2011 by using multilevel analysis. A total of 5,042 students from 153 classrooms of 150 schools participated in the TIMSS 2011 study, in which they were required to complete questionnaires. A 3-level multilevel analysis was used to assess the influence of factors at 3 levels on the science performance of 8th-grade Taiwanese students. The results showed that the provision of education resources at home, teachers' level of education, and school climate were the strongest predictor of science performance at the student, classroom, and school level, respectively. It was concluded that the science performance of 8th-grade Taiwanese students is driven largely by individual factors. Classroom-level factors accounted for a smaller proportion of the total variance in science performance than did school-level factors.

    The objective of this study was to determine the acute gastrointestinal effects caused by the consumption of drinking water containing graded levels of added copper. Sixty healthy, adult women were randomly assigned to receive copper [Cu(II)] at four concentrations in their drinking water following a Latin-square design. Each group (n = 15) received tap water with no added copper, 1, 3, and 5 mg Cu/l of added copper sulfate for a 2-week study period, followed by 1 week of standard tap water. The subjects recorded their water consumption and gastrointestinal symptoms daily on a special form. The average daily consumption of water was 1.64 liters per subject, regardless of the amount of copper added. Final serum copper, ceruloplasmin, and liver enzymes were measured in all subjects and were not different from baseline concentrations. Twenty-one subjects (35%) recorded gastrointestinal disturbances sometime during the study, 9 had diarrhea, some with abdominal pain and vomiting, and 12 subjects presented abdominal pain, nausea, or vomiting. There was no association between copper levels in drinking water and diarrhea. However, nausea, abdominal pain, or vomiting were significantly related to copper concentrations in water. The recorded incidence rate of these symptoms was 5, 2, 17, and 15% while ingesting water with 0, 1, 3, and 5 mg Cu/l, respectively (overall [chi]2 = 11.3, p<0.01; Cu [less than/equal to]1 mg/l versus Cu [Greater than/equal to]3 mg/l, [chi]2, p<0.01). When subjects interrupted their consumption of drinking water with added copper, most symptoms disappeared. We conclude that under the conditions of the study, there was no association between aggregate copper in drinking water within the range of 0-5 mg/l and diarrhea, but a [Greater than/equal to]3 mg Cu/l level of ionized copper was associated with nausea, abdominal pain, or vomiting. Additional studies with sufficient numbers of subjects are needed to define thresholds for specific gastrointestinal

    This study was conducted for 10 weeks with the aim of investigating the erythrocyte membrane integrity as measured by erythrocyte osmotic fragility and excitability scores of rabbits fed graded level of Hibiscus sabdariffa calyx (HSC). Twenty weaners' rabbit of both sexes were used for the study and were placed on four experimental diets which contain the following percentages of HSC 0 %, 25 %, 50 %, 75 %, as feed additive and were added at 0 g, 62.5 g, 125 g, 187.5 g designated as T1, T2, T3 and T4 experimental diets. Excitability scores were measured weekly as described by Voisnet et al. (1997). At the end of the experiment, the rabbits were slaughtered by severing the jugular vein. A Blood sample (2 ml) was collected from each rabbit into sampled bottles, containing the Na EDTA as anticoagulant for hematological analysis. Packed cell volume (PCV) Haemoglobin concentration (Hb), Total red blood cell (RBC) count, Total leukocyte count as well as differential leukocyte was determined using standard method. The percentage haemolysis recorded at 0.3 % to 0.8 % was significantly (P < 0.05) higher in rabbits in T1 compared to the remaining 3 diets. The result of excitability score shows that rabbit on diet 1 and 2 had a lower value which was significantly (P < 0.05) lower than rabbits on diets 3 and 4 with a value of 65.5 ± 5.0 and 70.00 ± 5.50 % respectively. In conclusion this study demonstrated for the first time that chronic administration of HSC improves haematological parameters, brain mood and function as well as maintaining erythrocyte membrane integrity.

    Background Subsets of high grade endometrial cancer (EnCa) over-express HER2 (ERBB2), yet clinical trials have failed to demonstrate any anti-tumor activity utilizing trastuzumab, an approved platform for HER2 positive breast cancer (BrCa). A truncated p95HER2 variant lacking the trastuzumab binding site may confer resistance. The objective of this investigation was to characterize the expression of the p95HER2 truncated variant in EnCa. Materials and Methods With institutional approval, 86 high grade EnCa tumors were identified with tumor specimens from surgeries performed between 2000-2011. Clinical data were collected and all specimens underwent tumor genotyping, HER2 immunohistochemistry (IHC, HercepTest®), HER2 fluorescent in situ hybridization (FISH), along with total HER2 (H2T) and p95HER2 assessment with VeraTag® testing. Regression models were used to compare a cohort of 86 breast tumors selected for equivalent HER2 protein expression. Results We identified 44 high grade endometrioid and 42 uterine serous carcinomas (USC). IHC identified high HER2 expression (2+ or 3+) in 59% of the tumors. HER2 gene amplification was observed in 16 tumors (12 USC, 4 endometrioid). Both HER2 gene amplification and protein expression correlated with H2T values. High p95HER2 expression above 2.8 RF/mm2 was observed in 53% (n = 54) with significant correlation with H2T levels. When matched to a cohort of 107 breast tumors based on HercepTest HER2 expression, high grade EnCa presented with higher p95 levels (p < 0.001). Conclusions: These data demonstrate that compared to BrCa, high grade EnCa expresses higher levels of p95HER2 possibly providing rationale for the trastuzumab resistance observed in EnCa.

    Emmandi, R; Sastry, M I S; Patel, M B

    2014-10-15

    A simple, sensitive, and accurate Ultraviolet Spectrophotometric method has been developed and validated for the determination of Benzene in Food Grade Hexane. Benzene in spectroscopic grade Hexane shows vibrational fine structure having four well resolved peaks. In the wavelength range 240-270nm, peak at 255nm is considered for the method development. Beer's law was obeyed in the concentration range of 0.6-10.0μLL(-1), with correlation coefficient, 0.9999, detection limit 0.2μLL(-1) and quantitation limit 0.6μLL(-1) are established. Percentage recovery studies showed that the method was not affected by the presence of other solvents having the similar boiling range with Hexane. The method was validated by determining its accuracy and precision which proves suitability of the developed method for the routine determination of Benzene in Food Grade Hexane. The proposed method has been applied successfully for the analysis of the Food Grade Hexane.

  18. School-based exposure to hazardous air pollutants and grade point average: A multi-level study.

    PubMed

    Grineski, Sara E; Clark-Reyna, Stephanie E; Collins, Timothy W

    2016-05-01

    The problem of environmental health hazards around schools is serious but it has been neglected by researchers and analysts. This is concerning because children are highly susceptible to the effects of chemical hazards. Some ecological studies have demonstrated that higher school-level pollution is associated with lower aggregate school-level standardized test scores likely, related to increased respiratory illnesses and/or impaired cognitive development. However, an important question remains unexamined: How do school-level exposures impact individual children's academic performance? To address this, we obtained socio-demographic and grades data from the parents of 1888 fourth and fifth grade children in the El Paso (Texas, USA) Independent School District in 2012. El Paso is located on the US-side of the Mexican border and has a majority Mexican-origin population. School-based hazardous air pollution (HAP) exposure was calculated using census block-level US Environmental Protection Agency National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter (PM). School-level demographics were obtained from the school district. Multi-level models adjusting for individual-level covariates (e.g., age, sex, race/ethnicity, English proficiency, and economic deprivation) and school-level covariates (e.g., percent of students economically disadvantaged and student-teacher ratio) showed that higher school-level HAPs were associated with lower individual-level grade point averages. An interquartile range increase in school-level HAP exposure was associated with an adjusted 0.11-0.40 point decrease in individual students' grade point averages (GPAs), depending on HAP type and emission source. Respiratory risk from HAPs had a larger effect on GPA than did diesel PM risk. Non-road mobile and total respiratory risk had the largest effects on children's GPA of all HAP variables studied and only mother's level of education had a larger effect than those

    2008-07-01

    The 6th International Conference on Inverse Problems in Engineering: Theory and Practice (ICIPE 2008) belongs to a successful series of conferences held up to now following a three-year cycle. Previous conferences took place in Palm Coast, Florida, USA (1993), Le Croisic, France (1996), Port Ludlow, Washington, USA (1999), Angra dos Reis, Brazil (2002), and Cambridge, UK (2005). The conference has its roots on the informal seminars organized by Professor J V Beck at Michigan State University, which were initiated in 1987. The organization of this Conference, which took place in Dourdan (Paris) France, 15-19 June 2008, was made possible through a joint effort by four research departments from four different universities: LEMTA (Laboratoire de Mécanique Théorique et Appliquée, Nancy-Université) LMS (Laboratoire de Mécanique des Solides, Ecole Polytechnique, Paris) LMAC (Laboratoire de Mathématiques Appliquées, UTC Compiègne) LTN (Laboratoire de Thermocinétique, Université de Nantes) It received support from three organizations: SFT (Société Française de Thermique: French Heat Transfer Association) ACSM (Association Calcul de Structures et Simulation : Computational Structural Mechanics Association) GdR Ondes - CNRS (`Waves' Network, French National Center for Scientific Research) The objective of the conference was to provide the opportunity for interaction and cross-fertilization between designers of inverse methods and practitioners. The delegates came from very different fields, such as applied mathematics, heat transfer, solid mechanics, tomography.... Consequently the sessions were organised along mostly methodological topics in order to facilitate interaction among participants who might not meet otherwise. The present proceedings, published in the Journal of Physics: Conference Series, gathers the four plenary invited lectures and the full-length versions of 103 presentations. The latter have been reviewed by the scientific committee (see

  7. Guided-Inquiry Lessons Raise Scores on the Sixth Grade Georgia Science Test

    NASA Astrophysics Data System (ADS)

    Page, Purlie M.

    At the local level, G Middle School has the highest district-wide percentage of 6th grade science students who are not meeting standards. It is imperative that G middle school take corrective action to reduce the number of students failing to meet state science standards. Dewey's theory of conceptual framework, which involves knowledge constructed on a person's personal experience and mind activity through active forms of learning, guided this study. The goal of the study was to determine whether inquiry-based science modules produce greater 6th grade science achievement, as measured by an equivalent instrument of the science section of the Georgia Criterion-Referenced Competency Test, when compared to traditional instruction among eastern Georgia 6th graders. The sample consisted of 230 students in the nonintervention group and 119 students in the intervention group. All students were from intact classes. At the end of the intervention, an independent t test was conducted to analyze the scores. According to the study t test, (t = 12.33, df = 304.56, p < 0.05), the difference between the means was statistically significant. This project's potential impact on social change includes increasing student motivation towards, comprehension of, and interest in science concepts. At the local level, these inquiry lessons can be shared with science teachers across grade levels and within the district to improve county-wide science scores. An increase in student interest and comprehension of science concepts could ultimately lead to the United States producing more students in the fields of science, technology, engineering, and mathematics (STEM) education.

  15. Self-regulation, motivation, and math achievement in middle school: variations across grade level and math context.

    PubMed

    Cleary, Timothy J; Chen, Peggy P

    2009-10-01

    The current study examined grade level, achievement group, and math-course-type differences in student self-regulation and motivation in a sample of 880 suburban middle-school students. Analysis of variance was utilized to assess group differences in student self-regulation and motivation, and linear regression analysis was used to identify variables that best predicted students' use of regulatory strategies. A key finding was that although seventh graders exhibited a more maladaptive self-regulation and motivation profile than sixth graders, achievement groups in seventh grade (high, moderate, low) were more clearly differentiated across both self-regulation and motivation than achievement groups in sixth grade. The pattern of achievement group differences also varied across math course type, as self-regulation and motivation processes more consistently differentiated achievement groups in advanced classes than regular math courses. Finally, task interest was shown to be the primary motivational predictor of students' use of regulatory strategies during math learning. The study highlights the importance of identifying shifting student motivation and self-regulation during the early middle school years and the potential role that context may have on these processes.

  16. The effect of the level of aggression in the first grade classroom on the course and malleability of aggressive behavior into middle school.

    Kellam, S G; Ling, X; Merisca, R; Brown, C H; Ialongo, N

    1998-01-01

    This paper is on the influences of the classroom context on the course and malleability of aggressive behavior from entrance into first grade through the transition into middle school. Nineteen public elementary schools participated in developmental epidemiologically based preventive trials in first and second grades, one of which was directed at reducing aggressive, disruptive behavior. At the start of first grade, schools and teachers were randomly assigned to intervention or control conditions. Children within each school were assigned sequentially to classrooms from alphabetized lists, followed by checking to insure balanced assignment based on kindergarten behavior. Despite these procedures, by the end of first quarter, classrooms within schools differed markedly in levels of aggressive behavior. Children were followed through sixth grade, where their aggressive behavior was rated by middle school teachers. Strong interactive effects were found on the risk of being highly aggressive in middle school between the level of aggressive behavior in the first grade classrooms and each boy's own level of aggressive, disruptive behavior in first grade. The more aggressive first grade boys who were in higher aggressive first grade classrooms were at markedly increased risk, compared both to the median first grade boys, and compared to aggressive males in lower aggressive first grade classrooms. Boys were already behaving more aggressively than girls in first grade; and no similar classroom aggression effect was found among girls, although girls' own aggressive behavior did place them at increased risk. The preventive intervention effect, already reported elsewhere to reduce aggressive behavior among the more aggressive males, appeared to do so by reducing high levels of classroom aggression. First grade males' own poverty level was associated with higher risk of being more aggressive, disruptive in first grade, and thereby increased their vulnerability to classroom

  17. Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

    NASA Astrophysics Data System (ADS)

    Williams, Richard L.; Yore, Larry D.

    Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

    Terracottas from the 6th century B.C.; a description of a delivery written in 1780; and a description of a labor chair used until 1914 give an historical picture of childbirth on the Greek island of Chios. The terracottas establish the fact that women were delivered in an upright perpendicular position in classical times. The upright labor chair seems to have continued in use until 1914. Midwives have historically at deliveries. In Chios, doctors seem to have taken over from midwives only around 1914.

    The purpose of this study was to develop and calibrate health-relatedfitness portfolios for 1st-6th grade students using the many-faceted Rasch model, and examine advantages and disadvantages of a portfolio assessment system based on Rasch calibration. Nine hundred ninety-five studentsfrom 23 schools infirst-sixth grade, who completed three-six of nine health-related fitness portfolios, participated in this study. Ten physical education teachers performed the grading across various portfolios and grade levels. Students'portfolios were rated using 23 predeveloped rubrics, and their scores linked through several common portfolios that were used across schools. The rating scores were analyzed using the many-faceted Rasch model, with four defined facets: portfolio, rubric, student, and rater The model-data fit was very good, and a consistent grade difference wasfound, that is, older students scored higher in fitness knowledge than younger ones. With Rasch calibration, measurement problems in conventional portfolio assessments can be eliminated, and a valid and reliable assessment system can be developed. In addition, several other measurement advantages are provided by Rasch calibration (e.g., related facets can be examined and controlled simultaneously). A large sample size and a more complex process, however, are required in the calibration stage of developing such a system using the Rasch model.

    Differences were examined in Theory of Planned Behaviour determinants of students' intention to smoke including parents' attitudes towards smoking and parents' current cigarette use among Greek students of different school grade levels. Students (N = 763) aged 10-18 years reported their attitudes towards smoking, subjective norms, perceived behavioural control, self-identity and intention to smoke while their parents (N = 525) reported their attitudes towards smoking and their current cigarette use. All the TPB variables increased from lower to higher school grade level. Multi-sample path analyses showed that parent's attitudes towards smoking positively predicted students' intention to smoke only for elementary school children. Parents' current cigarette use did not contribute significantly. Students' attitudes, perceived behavioural control and self-identity predicted systematically intention to smoke in contrast to the subjective norm that did not contribute at all. Perceived behavioural control contributed to a higher degree in intention to smoke for senior high school students compared to the junior high school and elementary students. Self-identity contributed to a higher degree in intention to smoke for elementary compared to the junior high school students. The results of this study suggests that the determinants of smoking vary between early and late adolescence.

    Maya societies in Southern Mexico, Guatemala and Belize experienced a 'dark age' during the second half of the 6th century. This period, also known as the 'Maya Hiatus', is characterized by cultural downturn, political instability and abandonment of many sites in the Central Maya Lowlands. Many theories have been postulated to explain the occurrence of this 'dark age' in Maya history. A possible key role of a large volcanic eruption in the onset of this 'dark age' will be discussed. Volcanic deposits recovered from the sedimentary archive of lake Tuspán and the Usumacinta-Grijalva delta were studied in detail and the combination of multiple dating techniques allowed the reconstruction of the timing of a large 6th century eruption. Volcanic glass shards were fingerprinted to indicate the source volcano and high resolution pollen records were constructed to indicate the environmental impact of the eruption. Results are compared with available archaeological data and causality with the disruption of Maya civilization will be evaluated.

  14. Graded levels of Ptf1a differentially regulate endocrine and exocrine fates in the developing pancreas

    The mechanisms regulating pancreatic endocrine versus exocrine fate are not well defined. By analyzing the effects of Ptf1a partial loss of function, we uncovered novel roles for this transcription factor in determining pancreatic fates. In a newly identified hypomorphic ptf1a mutant, pancreatic cells that would normally express ptf1a and become exocrine cells, express the endocrine marker Isl1, indicating a cell fate switch. Surprisingly, a milder reduction of Ptf1a leads to an even greater increase of ectopic endocrine cells, suggesting that Ptf1a also plays a role in promoting endocrine development. We propose that low levels of Ptf1a promote endocrine fate, whereas high levels repress endocrine fate and promote exocrine fate. PMID:18519637

    1992-01-01

    Acquired cold urticaria with a negative cold stimulation test has been described in seven patients in whom the standard ice cube test did not induce localized urticaria. Subsequent total body cold exposure induced a generalized urticaria. A patient with this syndrome is presented where blood histamine levels rose from 9 to 60 micrograms/dL after a negative local cold stimulation test and from 60 to 90 micrograms/dL after total body cold exposure. Urticaria occurred only after generalized cold exposure. Blood histamine levels following the ice cube test may represent a sensitive method to diagnose this form of atypical acquired cold urticaria, without subjecting the patient to the risk of anaphylaxis reported following total body cold exposure.

    A feeding trial was performed to investigate inclusion levels of distillers dried grains with solubles (DDGS) as a fishmeal replacement for juvenile Nile tilapia (Oreochromis niloticus). On a dry matter basis, five isocaloric [19.3 ± 0.4 kJ/g (mean ± SE)], isonitrogenous (39.1 ± 0.5% crude protein) diets were formulated to contain 17.5%, 20%, 22.5%, 25%, and 27.5% DDGS and compared against a 0% DDGS, reference diet (gross energy = 14.5 kJ/g; crude protein = 39.8%). The reference diet resulted in significantly higher body weight gain (BWG), food conversion ratio (FCR), and protein efficiency ratio (PER) than experimental diets except that 17.5% DDGS provided similar FCR and PER. The diet containing 27.5% DDGS had significantly lower FCR and PER values than all other diets even though apparent digestibility did not significantly differ among experimental diets. Although DDGS can be incorporated at higher levels, 20% DDGS provided the highest apparent BWG among experimental diets, while 17.5% promoted the best FCR and PER. Fishmeal may be replaced with low levels of fuel-based DDGS to reduce feeding cost; however, additional supplements should be considered to enhance fish performance.

    Systems biology recognizes the complex multi-scale organization of biological systems, from molecules to ecosystems. The International Symposium on Systems Biology is an annual two-day event gathering the most influential researchers transforming biology into an integrative discipline investigating complex systems. In recognition of the fundamental similarity between the scientific problems addressed in environmental science and systems biology studies at the molecular, cellular, and organismal levels, the 2007 Symposium featured global leaders in “Systems Biology and the Environment.” The objective of the 2007 “Systems Biology and the Environment” International Symposium was to stimulate interdisciplinary thinking and research that spans systems biology and environmental science. This Symposium was well aligned with the DOE’s Genomics: GTL program efforts to achieve scientific objectives for each of the three DOE missions: Develop biofuels as a major secure energy source for this century; Develop biological solutions for intractable environmental problems; Understand biosystems’ climate impacts and assess sequestration strategies. Our scientific program highlighted world-class research exemplifying these priorities. The Symposium featured 45 minute lectures from 12 researchers including: Penny/Sallie Chisholm of MIT gave the keynote address “Tiny Cells, Global Impact: What Prochlorococcus Can Teach Us About Systems Biology”, plus Jim Fredrickson of PNNL, Nitin Baliga of ISB, Steve Briggs of UCSD, David Cox of Perlegen Sciences, Antoine Danchin of Institut Pasteur, John Delaney of the U of Washington, John Groopman of Johns Hopkins, Ben Kerr of the U of Washington, Steve Koonin of BP, Elliott Meyerowitz of Caltech, and Ed Rubin of LBNL. The 2007 Symposium promoted DOE’s three mission areas among scientists from multiple disciplines representing academia, non-profit research institutions, and the private sector.

    Relics of amber were excavated from King Muryeong's tomb constructed in the 6th century on the Korean peninsula. To estimate the provenance, FTIR (Fourier transform infrared spectroscopy) and py/GC/MS (pyrolysis/gas chromatography/mass spectrometry) analysis were utilized. The reference Baltic amber sample was also analyzed with the same method for comparison. The relics were confirmed to be amber from the FTIR analysis where an absorption band near 1150 cm- 1, characteristic one in Baltic amber, was also observed. In py/GC/MS analysis, pyrolyzed products like butanedioic acid and dehydroabietic acid, known constituents of amber, were observed. In addition, D-fenchyl alcohol, camphor, borneol and butanedioic acid, typical constituents of Baltic amber, were observed in some samples. From this, it appears that some of relics were made from Baltic amber and that Baltic amber was transported to the Korean peninsula in the time of tomb construction.

  1. The optimum level of parent participation: A study of three intensity levels of parent involvement during three "Playtime is Science" units in three third-grade classes

    NASA Astrophysics Data System (ADS)

    Gooden, Kelly Lynn

    The study describes the experience of introducing three intensity levels of parent participation in three third-grade classes for science instruction using Playtime is Science; an equity curriculum that utilizes parent participation. The study sought to determine the optimum level of participation by ascertaining the most influential aspect of involvement on proficiency scores and the most important aspect of involvement to participants. The levels of participation intensity were distinguished by: (1) the number of parents in the classroom; (2) the responsibilities of the parents; (3) the training received; and (4) the number of students with whom the parents worked. Involvement at each level would potentially manifest aspects of role modeling, lowered student-to-adult instructional ratio, and parent expertise to varying degrees. The three levels of participation were introduced during explorations in three Playtime is Science units following a rotation schedule. Student proficiency was assessed through scores on pre- and post-tests, journals, and discourse. ANCOVA was used to identify main and interaction effects of the independent variables (class, unit and level) on student proficiency taking into account existing differences in groups. Participant attitudes were assessed through journals and interviews. Observations of explorations triangulated findings and assessed participant interactions. Field notes, transcripts and photographs were coded according to the aspects of parent involvement. The results showed level of parent intensity of involvement had no affect on proficiency scores. Therefore, no aspect of parent involvement was determined to be the most influential. Participants felt that lowered instructional ratio and role modeling were the most important aspects of involvement. The level of involvement that utilized the lowest ratio and the most role modeling was level III, small group facilitators. Level III was recognized as the optimum level of

    Arsenic exposure in children is a public health concern but is understudied in relation to the predictors, and effects of low-level exposure. We examined the extent and dietary predictors of exposure to inorganic arsenic in 5-8 year old children from Montevideo, Uruguay. Children were recruited at school; 357 were enrolled, 328 collected morning urine samples, and 317 had two 24-h dietary recalls. Urinary arsenic metabolites, i.e. inorganic arsenic (iAs), methylarsonic acid (MMA), and dimethylarsinic acid (DMA), were measured using high-performance liquid chromatography with hydride generation and inductively coupled plasma mass spectrometry (HPLC-HG-ICP-MS), and the sum concentration (U-As) used for exposure assessment. Proportions of arsenic metabolites (%iAs, %MMA and %DMA) in urine were modelled in OLS regressions as functions of food groups, dietary patterns, nutrient intake, and nutritional status. Exposure to arsenic was low (median U-As: 9.9µg/L) and household water (water As: median 0.45µg/L) was not a major contributor to exposure. Children with higher consumption of rice had higher U-As but lower %iAs, %MMA, and higher %DMA. Children with higher meat consumption had lower %iAs and higher %DMA. Higher scores on "nutrient dense" dietary pattern were related to lower %iAs and %MMA, and higher %DMA. Higher intake of dietary folate was associated with lower %MMA and higher %DMA. Overweight children had lower %MMA and higher %DMA than normal-weight children. In summary, rice was an important predictor of exposure to inorganic arsenic and DMA. Higher meat and folate consumption, diet rich in green leafy and red-orange vegetables and eggs, and higher BMI contributed to higher arsenic methylation capacity.

    The levels of smoking of 1st and 2nd year students at Faculty of Medicine and Manisa School of Health at Celal Bayar University were investigated in 2006-2007. This study is carried out in order to see if there is a change in the same students' level of smoking while they are in 3rd and 4th year. In addition, the study aimed to examine the factors affecting the level of use and attitudes towards the law effectuated in July 19, 2009. This is a follow-up study with 80.42% return rate. A 26-item structured questionnaire was administered. The participants filled out the questionnaires under supervision of the researchers in their classrooms. The University Institutional Review Board approved the study. The total of participants (263) of the follow-up study included 189 female and 74 male. The rate of experimenting with smoking was 49% with the mean age of 15.7 (SD= 4.01 years). The mean age of experimenting with smoking was the earliest on male students studying at faculty of medicine. The level of smoking was found to be the most on females, studying at faculty of medicine and staying at the dormitory, with smoking parents (p< 0.05). The most important reason to begin smoking was curiosity (55.2%) while bad breath and yellowing of teeth were the reasons to quit (91.7%). 83.3% of the students thought that the law will be effective on quit smoking. The level of both experimenting and use of smoking has been increased over time. It is suggested that medical students' awareness about the danger of smoking should be raised at earlier grades. In addition, lectures should be offered to students at School of Health and they should be encouraged to unite in order to fight with smoking.

    Colorimetric artificial tongue and nose were used to discriminate nine Chinese green teas from different geographical origins and grade levels. Printing nanoporous porphyrin, dimeric metalloporphyrins, metallosalophen complexes and chemically responsive dyes on a hydrophobic membrane, the developed sensor array of artificial tongue and nose showed a unique pattern of colorimetric change upon exposure to green tea liquids or gases. All green tea samples, both in liquid and gas analysis, gave distinct patterns according to geographical origin and grade level, thus resulting in their facile identification. The good reproducibility of colorimetric artificial tongue and nose was proved. Data analysis was performed by chemometric techniques: hierarchical cluster analysis (HCA), and principal component analysis (PCA). Chinese green tea from the same geographical origin could cluster together in PCA score plot. No errors in classification by HCA were observed in 90 trials. The colorimetric artificial tongue and nose can be used to discriminate Chinese green tea according to geographical origin and grade level.

  13. Photometric and Spectroscopic Footprint Corrections in the Sloan Digital Sky Survey’s 6th Data Release

    NASA Astrophysics Data System (ADS)

    2016-04-01

    We identify and correct numerous errors within the photometric and spectroscopic footprints (SFs) of the Sloan Digital Sky Survey’s (SDSS) 6th data release (DR6). Within the SDSS’s boundaries hundreds of millions of objects have been detected. Yet we present evidence that the boundaries themselves contain a significant number of mistakes that are being revealed for the first time within this paper. Left unaddressed, these can introduce systematic biases into galaxy clustering statistics. Using the DR6 Main Galaxy Sample (MGS) targets as tracers, we reveal inconsistencies between the photometric and SF definitions provided in the Catalog Archive Server (CAS), and the measurements of targets therein. First, we find that 19.7 deg2 of the DR6 photometric footprint are devoid of MGS targets. In volumes of radii 7 {h}-1 {Mpc}, this can cause errors in the expected number of galaxies to exceed 60%. Second, we identify seven areas that were erroneously included or excluded from the SF. Moreover, the tiling algorithm that positioned spectroscopic fibers during and between DRs caused many areas along the edge of the SF to be significantly undersampled relative to the footprint’s interior. Through our corrections, we increase the completeness 2.2% by trimming 3.6% of the area from the existing SF. The sum total of these efforts has generated the most accurate description of the SDSS DR6 footprints ever created.

    Objectives: This in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (PAT). Materials and Methods: Thirty-six primary anterior teeth were randomly divided into 3 groups of 5th generation (Single Bond 2), 6th generation (Clearfil SE) and 7th generation (Single Bond Universal) bonding agents. The canal orifice was restored with composite resin and the push-out test was carried out to assess the bond strength. After applying the push-out load, specimens were evaluated under a light microscope at 40X magnification. One-way ANOVA and log-rank test on Kaplan-Meier curves were applied for the comparison of bond strength among the 3 groups. Results: The mean± standard deviation (SD) bond strength was 13.6±5.33 MPa for Single Bond 2, 13.85±5.86 MPa for Clearfil SE and 12.28±5.24 MPa for Single Bond Universal. The differences in bond strength among the 3 groups were not statistically significant (P>0.05). Conclusion: All three bonding agents are recommended for use with composite posts in PAT. However, due to high technical sensitivity of the Total Etch system, single or two-step self etch systems may be preferred for uncooperative children. PMID:26056518

    Yersinia pestis, the etiologic agent of the disease plague, has been implicated in three historical pandemics. These include the third pandemic of the 19(th) and 20(th) centuries, during which plague was spread around the world, and the second pandemic of the 14(th)-17(th) centuries, which included the infamous epidemic known as the Black Death. Previous studies have confirmed that Y. pestis caused these two more recent pandemics. However, a highly spirited debate still continues as to whether Y. pestis caused the so-called Justinianic Plague of the 6(th)-8(th) centuries AD. By analyzing ancient DNA in two independent ancient DNA laboratories, we confirmed unambiguously the presence of Y. pestis DNA in human skeletal remains from an Early Medieval cemetery. In addition, we narrowed the phylogenetic position of the responsible strain down to major branch 0 on the Y. pestis phylogeny, specifically between nodes N03 and N05. Our findings confirm that Y. pestis was responsible for the Justinianic Plague, which should end the controversy regarding the etiology of this pandemic. The first genotype of a Y. pestis strain that caused the Late Antique plague provides important information about the history of the plague bacillus and suggests that the first pandemic also originated in Asia, similar to the other two plague pandemics.

    Cloned livestock have potential importance in the provision of improved medicine as well as in the development of livestock production. The public is, however, increasingly concerned about the social and ethical consequences of these advances in knowledge and techniques. There is unevenness throughout Europe in different Member States' attitudes to research into livestock cloning. Although there is EU legislation controlling the use of animals for research purposes, there is no legislation specifically governing cloning in livestock production. The main EU reference is the 9th Opinion of the European Group on Ethics, which states "Cloning of farm animals may prove to be of medical and agricultural as well as economic benefit. It is acceptable only when the aims and methods are ethically justified and when carried out under ethical conditions." The ethical justification includes the avoidance of suffering, the use of the 3Rs principle and a lack of better alternatives. The Commission addresses these issues in the 6th Framework Programme by promoting the integration of ethical, legal and social aspects in all proposals where they are relevant, by fostering ethical awareness and foresight in the proposals, by encouraging public dialogue, and by supporting specific actions to promote the debate. Research must respect fundamental ethical principles, including animal welfare requirements.

    Sequential regression was used to evaluate whether language-related working memory components uniquely predict reading and writing achievement beyond cognitive-linguistic translation for students in Grades 4 through 9 ( N = 103) with specific learning disabilities (SLDs) in subword handwriting (dysgraphia, n = 25), word reading and spelling (dyslexia, n = 60), or oral and written language (oral and written language learning disabilities, n = 18). That is, SLDs are defined on the basis of cascading level of language impairment (subword, word, and syntax/text). A five-block regression model sequentially predicted literacy achievement from cognitive-linguistic translation (Block 1); working memory components for word-form coding (Block 2), phonological and orthographic loops (Block 3), and supervisory focused or switching attention (Block 4); and SLD groups (Block 5). Results showed that cognitive-linguistic translation explained an average of 27% and 15% of the variance in reading and writing achievement, respectively, but working memory components explained an additional 39% and 27% of variance. Orthographic word-form coding uniquely predicted nearly every measure, whereas attention switching uniquely predicted only reading. Finally, differences in reading and writing persisted between dyslexia and dysgraphia, with dysgraphia higher, even after controlling for Block 1 to 4 predictors. Differences in literacy achievement between students with dyslexia and oral and written language learning disabilities were largely explained by the Block 1 predictors. Applications to identifying and teaching students with these SLDs are discussed.

    Defining the aggressiveness and growth rate of a malignant cell population is a key step in the clinical approach to treating tumor disease. The correct grading of breast cancer (BC) is a fundamental part in determining the appropriate treatment. Biological variables can make it difficult to elucidate the mechanisms underlying BC development. To identify potential markers that can be used for BC classification, we analyzed mRNAs expression profiles, gene copy numbers, microRNAs expression and their association with tumor grade in BC microarray-derived datasets. From mRNA expression results, we found that grade 2 BC is most likely a mixture of grade 1 and grade 3 that have been misclassified, being described by the gene signature of either grade 1 or grade 3. We assessed the potential of the new approach of integrating mRNA expression profile, copy number alterations, and microRNA expression levels to select a limited number of genomic BC biomarkers. The combination of mRNA profile analysis and copy number data with microRNA expression levels led to the identification of two gene signatures of 42 and 4 altered genes (FOXM1, KPNA4, H2AFV and DDX19A) respectively, the latter obtained through a meta-analytical procedure. The 42-based gene signature identifies 4 classes of up- or down-regulated microRNAs (17 microRNAs) and of their 17 target mRNA, and the 4-based genes signature identified 4 microRNAs (Hsa-miR-320d, Hsa-miR-139-5p, Hsa-miR-567 and Hsa-let-7c). These results are discussed from a biological point of view with respect to pathological features of BC. Our identified mRNAs and microRNAs were validated as prognostic factors of BC disease progression, and could potentially facilitate the implementation of assays for laboratory validation, due to their reduced number.

    The aim of the study was to evaluate the effect of graded levels of Enterolobium cyclocarpum pods in the ration on feed intake and digestibility by Pelibuey lambs. Five dietary treatments were imposed where ground pods replaced concentrate diet at 0, 20, 30, 40 and 50 % of dry matter (DM), respectively. The concentrate portion was composed of ground sorghum, soybean meal, cane molasses and minerals. Five entire Pelibuey lambs with initial bodyweight 34 ± 2 kg were allocated in the treatments in a 5 × 5 Latin square design. Values of dry matter intake (DMI) and dry matter (DMD) and organic matter (OMD) digestibility were measured and metabolisable energy intake (MEI) estimated. Rumen degradation constants for E. cyclocarpum were also measured. There were no differences (P > 0.05) in average DMI (86.6 g/kg(0.75)) and OMI (81.2 g/kg(0.75)) among treatments. As the level of incorporation of E. cyclocarpum pods increased, voluntary DMI and OMI increased, whereas apparent DMD and OMD decreased linearly. Average digestible DM (65 g/kg(0.75)) and OM (61 g/kg(0.75)) intakes were similar (P > 0.05) among treatments. Similarly, MEI (0.976 MJ ME kg(0.75)/day) was not different (P > 0.05) among treatments. The potential rumen degradation (A + B) of ground pods of E. cyclocarpum was 866.4 g/kg DM. Ground pods of E. cyclocarpum can be employed for lamb feeding up to 50 % of the ration, without affecting DMI, DM apparent digestibility and MEI.

    The objective of this study was to investigate the effects of graded levels of isomaltooligosaccharides (IMO) on the performance, immune function and intestinal microflora and intestinal mucosal morphology of weaned pigs. In a 28-day experiment, one hundred eighty, twenty eight-day-old, crossbred (Duroc×Large White×Landrace), weaned pigs, with an initial body weight of 8.19±1.45 kg, were fed either an unsupplemented corn-soybean meal based diet or similar diets supplemented with 0.2%, 0.4%, 0.6%, or 0.8% IMO added at the expense of corn. Each treatment was replicated six times with six pigs (three barrows and three gilts) per pen. From day 0 to 14, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p = 0.05) linearly declined as the IMO level increased. On d 14, the level of the immunoglobulins IgA, IgM, and IgG in the serum of pigs were linearly increased (p<0.05) with increasing IMO supplementation. Interleukin-6 (IL-6) was linearly (p<0.05) and quadratically (p<0.05) decreased as IMO intake increased. From day 15 to 28, there was a trend for weight gain to be linearly increased, and IL-2 was linearly (p<0.05) increased as IMO supplementation increased on d 28. Over the entire experiment, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p<0.05) was linearly decreased as the IMO level increased. Supplementation with IMO had no effect on the intestinal microflora of pigs in the ileum and cecum of pigs, as well as the villus height and crypt depth in the ileum and jejunum (p>0.05). These results indicate that dietary inclusion of IMO increases weight gain, gain:feed and enhanced the immune status of pigs, and could be a valuable feed additive for use in weaned pigs, particularly during the period immediately after weaning.

    Few decades ago, the dilatancy-diffusion hypothesis held great promise as a physical basis for developing earthquakes prediction techniques, but the potential never become reality, as the result of too few observations consistent with the theory. One of the main problems has been the lack of detailed monitoring records of small earthquakes swarms spatio-temporally close to the incoming major earthquakes. In fact, the recognition of dilatancy-related effects requires the use of very dense network of three-component seismographs, which, in turn, implies the a-priori knowledge of major earthquakes location, i.e., actually a paradox. The deterministic prediction of earthquakes remains a long time, hard task to accomplish. Nevertheless, for seismologists, the understanding of the processes that preside over the earthquakes nucleation and the mechanics of faulting represents a big step toward the ability to predict earthquakes. Here we describe a set of seismological observations done on the foreshock sequence that preceded the April 6th 2009, Mw 6.3, L’Aquila earthquake. In this occasion, the dense configuration of the seismic network in the area gave us the unique opportunity for a detailed reconstruction of the preparatory phase of the main shock. We show that measurable precursory effects, as changes of the seismic waves velocity and of the anisotropic parameters in the crust, occurred before the main shock. From our observations we infer that fluids play a key role in the fault failure process, and, most significantly, that the elastic properties of the rock volume surrounding the main shock nucleation area undergo a dramatic change about a week before the main shock occurrence.

    The future 7th edition of TNM classification for lung cancer will be published in 2009 and comprises the IASLC recommendations for TNM parameters. The general staging of lung cancer includes the new parameters: reclassification of tumours larger than 7 cm from T2 to T3; extra tumoral nodules will change their category to T3, T4 and M1 when in the same, ipsilateral or contralateral lobe, respectively; pleural effusion will be M1a. With these alterations, cases staged as IB - T2b N0 M0 will be IIA, cases staged IIB - T2a N1 M0 will be IIA and cases IIIB- T4 N0- -1 M0 will be IIIA. The 7(th) TNM edition recommendations were applied to 203 broncho -pulmonary carcinomas, concerning epidermoid carcinomas (83) and adenocarcinomas (120) registered in the archive of the Serviço de Anatomia Patológica of the Hospitais da Universidade de Coimbra - Portugal, previously submitted to surgical resection and lymph node excision. The following alterations will be kept as the application of the future 7(th) TNM edition: 20 cases in stage IB will move to stage IIA (17) and stage IIB (3); 18 cases will change from stage IIB to stage IIA (17) and 1 case to stage IIIA; 2 cases from stage IIIB will move to stage IV; 6 cases in stage IV will move to stage IIIA (5) and 1 case to stage IIIB. In this translational adaptation from 6th to 7th TNM staging, 51 out of the 203 analysed cases change their staging, corresponding to 25.1%.

    Canned sardines are a ready-to-use fish product with excellent nutritional properties owing to its high n-3 long-chain PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-3). The present study aimed to assess the effect of two dosages of canned sardines, recommended for the primary and secondary prevention of human CVD, on the inflammatory marker concentrations and fatty acid composition of erythrocytes and key metabolic tissues (liver, muscle, adipose tissue and brain) in the rat model. Wistar rats were fed a diet containing 11 % (w/w) of canned sardines (low-sardine (LS) diet) and a diet containing 22 % (w/w) of canned sardines (high-sardine (HS) diet) for 10 weeks. Daily food intake, weight gain, and organ and final body weights were not affected by the dietary treatments. The concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol decreased in both the LS and HS groups, while those of alanine aminotransferase and adiponectin increased. The concentrations of IL-1β increased only with the highest dosage of sardine. The dose-dependent influence of the graded levels of EPA+DHA was tissue specific. Compared with that of other tissues and erythrocytes, the fatty acid composition of the brain was less affected by the canned sardine-supplemented diets. In contrast, the retroperitoneal adipose tissue was highly responsive. The deposition ratios of EPA and DHA indicated that the LS diet was optimal for DHA deposition across the tissues, except in the retroperitoneal adipose tissue. Taken together, our findings indicate that a LS diet positively affects plasma lipid profiles and inflammatory mediators, whereas a HS diet has contradictory effects on IL-1β, which, in turn, is not associated with variations in the concentrations of other pro-inflammatory cytokines. This finding requires further investigation and pathophysiological understanding.

    The main purposes of the present study are to investigate the differences on student's attitudes toward physics and their perceptions regarding classroom climate during physics classes based on gender and grade level. In addition, the study also explores female students' opinions about physics, and examines to what extent this factor might influence their decision to choose or not to choose physics or physics-related fields for their career choices in the future. A group of approximately 864 male and female students, equally proportioned by gender, were assigned to take part in this study. Two standardized instruments, namely the Individualized Classroom Environment Questionnaire (ICEQ) and the Test of Science Related Attitudes (TOSRA), have been employed to collect data. A combination of quantitative and qualitative methods was used to analyze the collected data resulting from the questionnaires as well as from the interviews. The study found, first, regardless of their gender and grade level differences, students expected a more positive classroom climate during learning physics. Also, it has been found that male students experience a more positive classroom environment than female students. Second, the study found that male students do show more positive attitudes toward physics than their female counterparts. Meanwhile, twelfth-grade students show a more positive attitude toward physics than eleventh-graders. Third, the study found that most female students do not like physics based on several reasons such as physics is a hard, monotonous and boring subject. Although eleventh-grade female students do not like physics, most of them intended to choose science as their major in the next grade. Surprisingly, a majority of twelfth-grade female students who are majoring in science have no intention to choose physics or physics-related subjects either for their prospective major at the university or for their career choices in the future.

    The achievement of recommended levels (≥ 30 min/day) of school moderate-to-vigorous physical activity (MVPA) is paramount to decrease risk of chronic disease in children from low-income families. The purpose of this study was to examine the predictors and grade-level trends of school day MVPA achievement in low-income children. Data were collected during the Fall of 2014 on 1232 children (Mean age = 8.8 ± 1.6 years; 625 girls, 607 boys) recruited from three low-income schools from the state of Utah in the U.S. Children wore pedometers for one school week and a stratified random subsample (n = 533) also wore accelerometers to record sedentary time and MVPA. Generalized linear mixed models were employed to calculate odds ratios for achieving school MVPA standards (≥ 30 min/day) from various predictors and to determine odds of achievement across grade levels, accounting for school and classroom clustering. Odds of meeting MVPA standards were 3 times greater if a student achieved at least 6000 steps during the school day (p < 0.01), and were 55% lower for every 1% increase in sedentary time (p < 0.001). Older children had 26% lower odds of meeting the recommended levels of MVPA compared to children in an immediately younger grade level (p < 0.05). A significant proportion of MVPA variance was explained by classroom and school affiliation (Rho = 0.09 to 0.54, p < 0.001). Daily steps, sedentary times, grade level, and classroom and school affiliation associate with school MVPA achievement in low-income children.

    Astronauts on long duration missions continue to experience bone loss, as much as 1-2% each month, for up to 4.5 years after a mission. Mechanical loading of bone with exercise has been shown to increase bone formation, mass, and geometry. The aim of this study was to compare the efficacy of two exercise protocols during a period of reduced gravitational loading (1/6th body weight) in mice. Since muscle contractions via resistance exercise impart the largest physiological loads on the skeleton, we hypothesized that resistance training (via vertical tower climbing) would better protect against the deleterious musculoskeletal effects of reduced gravitational weight bearing when compared to endurance exercise (treadmill running). Young adult female BALB/cBYJ mice were randomly assigned to three groups: 1/6 g (G/6; n=6), 1/6 g with treadmill running (G/6+RUN; n=8), or 1/6 g with vertical tower climbing (G/6+CLB; n=9). Exercise was performed five times per week. Reduced weight bearing for 21 days was achieved through a novel harness suspension system. Treadmill velocity (12-20 m/min) and daily run time duration (32-51 min) increased incrementally throughout the study. Bone geometry and volumetric bone mineral density (vBMD) at proximal metaphysis and mid-diaphysis tibia were assessed by in vivo peripheral quantitative computed tomography (pQCT) on days 0 and 21 and standard dynamic histomorphometry was performed on undemineralized sections of the mid-diaphysis after tissue harvest. G/6 caused a significant decrease (P<0.001) in proximal tibia metaphysis total vBMD (-9.6%). These reductions of tibia metaphyseal vBMD in G/6 mice were mitigated in both G/6+RUN and G/6+CLB groups (P<0.05). After 21 days of G/6, we saw an absolute increase in tibia mid-diaphysis vBMD and in distal metaphysis femur vBMD in both G/6+RUN and G/6+CLB mice (P<0.05). Substantial increases in endocortical and periosteal mineralizing surface (MS/BS) at mid-diaphysis tibia in G/6+CLB demonstrate that

    The Romanian Association of Medical Laboratories (RAML) conferences have acquired a reputation for standing out as the most prominent and efficient meetings in the national community of laboratory medicine, being a landmark of the development in this field in Romania and an active affiliation to international forums. This year, the conference setting was Piatra Neamt, in the northeast part of Romania, which produced a friendly and stimulating professional environment. As in previous years, leading experts in the fields of laboratory medicine attended the event. This year, we enjoyed the opportunity to have such distinguished guests as the members of the executive board of International Federation of Clinical Chemistry and Laboratory Medicine (IFCC); Graham Beastall, IFCC President; Päivi Hannele Laitinen, IFCC secretary; and Grazyna Sypniewska, IFCC Communication and Publication Division, and editor of the electronic journal of the IFCC. As usual, the conference program included all aspects of clinical laboratory activity, with a special focus on technology development, instrumentation and laboratory management. Fully aware of the fact that the complexity and depth of laboratory practice have undergone an impressive and rapid evolution, the specific goals of the event were to increase knowledge in the fundamentals of new molecular investigation, areas which show the tendency to become routine in our daily activity. In addition, laboratory management and the place of medical laboratories in the process of translational medicine were subjects of focus. The 6th Conference of the Romanian Association of Medical Laboratories was held from Wednesday 1st to Saturday 4th of June 2011. A total of 273 participants from all local branches of the Association attended. The scientific program included seven plenary sessions where 22 lectures and 18 short communications were delivered, and three poster sessions with 44 poster presentations. Session topics covered issues of

    The Synthetic Biology conference series (SBx.0) is the preeminent academic meeting in synthetic biology. Organized by the BioBricks Foundation, the SBx.0 conference series brings together leading researchers, students, industry executives, and policy makers from around the world to share, consider, debate, and plan efforts to make biology easier to engineer. Historically held every two years, the SBx.0 conferences are held in alternating locations in the United States, Europe, and Asia to encourage global participation and collaboration so that the ramifications of synthetic biology research and development are most likely to be safe ethical, and beneficial. On 9-11 July 2013, the 6th installment of the synthetic biology conference series (SB6.0) was held on the campus of Imperial College London (http://sb6.biobricks.org). The SB6.0 conference was attended by over 700 people, and many more were able to participate via video digital conference (http://sb6.biobricks.org/digital-conference/). Over the course of three days, the SB6.0 conference agenda included plenary sessions, workshops, and poster presentations covering topics ranging from the infrastructure needs arising when “Systematic Engineering Meets Biological Complexity” and design-led considerations for “Connecting People and Technologies” to discussions on “Engineering Biology for New Materials,” “Assessing Risk and Managing Biocontainment,” and “New Directions for Energy and Sustainability.” The $10,150 grant awarded by the U.S. Department of Energy (DE-SC0010233) to the BioBricks Foundation was used to provide partial reimbursement for the travel expenses of leading researchers from the United States to speak at the SB6.0 conference. A total of $9,450 was used to reimburse U.S. speakers for actual expenses related to the SB6.0 conference, including airfare (economy or coach only), ground transportation, hotel, and registration fees. In addition, $700 of the grant was used to offset

    2004-02-01

    Direct nanoscale and atomic resolution imaging is a key issue in nanoscience and nanotechnology. The invention of the dynamic force microscope in the early 1990s was an important step forward in this direction as this instrument provides a universal tool for measuring the topography and many other physical and chemical properties of surfaces at the nanoscale. Operation in the so-called non-contact mode now allows direct atomic resolution imaging of electrically insulating surfaces and nanostructures which has been an unsolved problem during the first decade of nanotechnology. Today, we face a most rapid development of the technique and an extension of its capabilities far beyond imaging; atomically resolved force spectroscopy provides information about local binding properties and researchers now develop sophisticated schemes of force controlled atomic manipulation with the tip of the force microscope. Progress in the field of non-contact force microscopy is discussed at the annually held NC-AFM conferences that are part of a series started in 1998 with a meeting in Osaka, Japan. The 6th International Conference on Non-contact Atomic Force Microscopy took place in Dingle, Ireland, from 31 August to 3 September 2003 and this special issue is a compilation of the original publications of work presented at this meeting. The papers published here well reflect recent achievements, current trends and some of the challenging new directions in non-contact force microscopy that have been discussed during the most stimulating conference days in Dingle. Fundamental aspects of forces and dissipation relevant in imaging and spectroscopy have been covered by experimental and theoretical contributions yielding a more detailed understanding of tip--surface interaction in force microscopy. Novel and improved imaging and spectroscopy techniques have been introduced that either improve the performance of force microscopy or pave the way towards new functionalities and applications

    Alcohol consumption by youth can produce negative health outcomes. This study identified correlates of lifetime alcohol use, recent alcohol use, and binge drinking among youth in sixth through 10th grade (n = 2,004) in Sarasota County, Fla. Results from a closed-ended, quantitative survey acknowledged a range of personal, social, and environmental influences. Breadth of these influences supports a need for multifaceted, community-based interventions for effective prevention of youth alcohol use. This study was unique because it represents population-specific research in which community partners are using the findings to develop community-specific social marketing interventions to prevent underage drinking and promote alternative behaviors.

  15. Comparison between the Strength Levels of Baseline Nuclear-Grade Graphite and Graphite Irradiated in AGC-2

    2015-07-01

    This report details the initial comparison of mechanical strength properties between the cylindrical nuclear-grade graphite specimens irradiated in the second Advanced Graphite Creep (AGC-2) experiment with the established baseline, or unirradiated, mechanical properties compiled in the Baseline Graphite Characterization program. The overall comparative analysis will describe the development of an appropriate test protocol for irradiated specimens, the execution of the mechanical tests on the AGC-2 sample population, and will further discuss the data in terms of developing an accurate irradiated property distribution in the limited amount of irradiated data by leveraging the considerably larger property datasets being captured in the Baseline Graphite Characterization program. Integrating information on the inherent variability in nuclear-grade graphite with more complete datasets is one of the goals of the VHTR Graphite Materials program. Between “sister” specimens, or specimens with the same geometry machined from the same sub-block of graphite from which the irradiated AGC specimens were extracted, and the Baseline datasets, a comprehensive body of data will exist that can provide both a direct and indirect indication of the full irradiated property distributions that can be expected of irradiated nuclear-grade graphite while in service in a VHTR system. While the most critical data will remain the actual irradiated property measurements, expansion of this data into accurate distributions based on the inherent variability in graphite properties will be a crucial step in qualifying graphite for nuclear use as a structural material in a VHTR environment.

    Background The validity of N classification of the 7th edition of the American Joint Committee on Cancer/Union Internationale contre le Cancer (AJCC/UICC) tumor-node-metastasis (TNM) staging system is still under debate. The purpose of this study was to evaluate the prognostic efficacy of the 7th edition of the AJCC/UICC TNM staging system (focusing on N stage), in comparison with the 6th edition, at a single Eastern institution. Methods We analyzed 1,435 patients with gastric cancer who underwent curative resection performed from September 1998 to August 2003 at the Memorial Jin-Pok Kim Korea Gastric Cancer Center. We analyzed the survival rate of the patients according to the AJCC/UICC 6th and 7th editions, and compared each stage, focusing on N stage. Results Significant differences in the 5-year survival rates were observed between the 6th and the 7th AJCC/UICC staging system. In the 6th edition staging system, the Kaplan-Meier curves discriminated each N stage significantly. In contrast, there was no difference in terms of survival curves for N stage according to the 7th edition, especially between N1 and N2: the Kaplan-Meier plots of survival curves between N1 (77.0%) and N2 (78.1%) stages overlapped significantly (p < 0.05). Conclusion Although the 7th UICC staging system is a more detailed and sophisticated system in the T category, there was no prognostic significance between the pN1 and pN2 stages according to our data. Therefore, we suggest establishing a new UICC staging system taking into consideration the application of the N stage. PMID:28203165

    During the seventies, Soviet archeologists conducted in Northern Iraq excavations of several ancient settlements dated from the Pottery Late Neolithic period (7th and 6th millennia BC). A very large collection of artifacts unearthed from these sites, in particular several thousands of well-documented pottery fragments, is now stored at the Archeological Institute in Moscow. We collected a time-sequential series of groups of potsherds from the multilayered settlement called Yarim Tepe II dated to the Halaf period (6th millennium BC). Each group comprises a minimum of 3 potsherds (up to 10) found within a same archeological layer, typically a thickness of about 20 cm. Altogether, the fragment groups encompass the entire 7-m thick stratigraphic sequence of Yarim Tepe II. We will present our first archeointensity results obtained using the experimental protocol developed for the Triaxe magnetometer, taking into account the effects of both the thermoremanent magnetization (TRM) anisotropy and the cooling rate dependence on TRM acquisition. The new data help to better constrain the geomagnetic field intensity variations in the Middle East during the 6th millennium BC. Thanks to the comparison with other datasets from Bulgaria and Syria, the new archeointensity results provide evidence for the occurrence of very rapid geomagnetic field intensity variations around 5500 BC.

    Introduction: On April 6th 2009 an earthquake of Mw=6.3 hit the historical downtown of L’Aquila and its hinterland causing more than 300 fatalities and severe damage to private and public buildings. At the time, the University of L’Aquila represented a major source of employment and income for the city. The earthquake impacted both the facilities and the administrative, financial and patrimonial activities of the university, bringing into the open the tendency – widespread in Italy – to rely on adaptive tactics rather than on strategic pre-disaster plans. This paper investigates the university’s emergency preparedness and response capability and  the strategies adopted to restore the education activities as well as avoid students migration to other universities. In addition, emphasis is placed on the role played by Student Associations in pre and post-disaster phases, and how students perceived the activities performed by these associations. Methods: To achieve this goal, it was undertaken: i) qualitative evaluation to assess the impact of earthquake on services and facilities of the university, the emergency preparedness and the measures adopted to face the emergency, ii) survey on the role played by Student Associations, both in emergency preparedness and response, according to students’ perception; iii) quantitative analysis to measure changes in the enrollment trend after the earthquake, and how university policies could curb students’ migration. Results: The policies adopted by the University allowed to diminish students’ migration; however, the measures taken by the university were based on an ad hoc plan as no emergency and continuity plans were prepared in advance. Similarly Student Associations got involved more in restoration activities than in emergency preparedness and risk awareness promotion. Discussion: Greater awareness and involvement are essential at each level (administrators, faculties, students) to plan in advance for an

    The Human papillomavirus is responsible for the most common sexually transmitted infection and is also known to be an oncogenic virus that is associated with cervical, anogenital, and head-neck cancers. The present study aims to assess whether oxidative DNA damage is correlated with the grade of HPV-related lesions. Moreover, we evaluated clinical data and unhealthy lifestyles to verify their possible influence on the genesis of oxidative DNA damage in cervical cells. We quantified the amount of 8-Oxo-2'-deoxyguanosine in DNA as a biomarker of oxidative damage in women with and without HPV infection. We also correlated oxidative damage with different stages of cervical lesions and available clinical data (e.g., HPV genotypes). To identify HPV infections, in which proteins with a transforming potential are produced, we performed a qualitative detection of HPV E6/E7 mRNA. Our results showed greater oxidative damage in HPV-related dysplastic cervical lesions compared to samples with normal cytology, especially in women with high-grade squamous intraepithelial lesions. The latter showed a closed link with high-risk HPV genotypes. Reactive oxygen species can induce DNA double-strand breaks in both the host DNA and in the circular viral episome; this could facilitate the integration of the virus, promoting HPV carcinogenesis. Therefore, in HPV-infected women, it could be useful to reduce additional resources of reactive oxygen/nitrogen species (RONS) with a healthy lifestyle.

    Serum B-lymphocyte stimulator (BLyS) levels are elevated in a subset of non-Hodgkin lymphoma (NHL) patients, particularly those with a family history of B-cell malignancies or a polymorphism in the BLyS gene. BLyS promotes growth of malignant B-cells and increased serum BLyS levels are associated with a poor clinical outcome. In this study, BLyS levels were measured before and after 4 weekly doses of rituximab in 30 patients with previously untreated follicular Grade 1 NHL. A significant increase was seen in the serum levels of BLyS (P = 0.0001) after rituximab therapy. The increase was independent of genetic variability in the BLyS gene. PMID:19051265

    The primary purpose of the study was to examine different variables (i.e. science process skill ability, science attitudes, and parents' levels of expectation for their children in science, which may impinge on science education differently for males and females in grades five, seven, and nine. The research question addressed by the study was: What are the differences between science process skill ability, science attitudes, and parents' levels of expectation in science on the academic success of fifth, seventh, and ninth graders in science and do effects differ according to gender and grade level? The subjects included fifth, seven, and ninth grade students ( n = 543) and their parents (n = 474) from six rural, public elementary schools and two rural, public middle schools in Southern Mississippi. A two-way (grade x gender) multivariate analysis of variance (MANOVA) was used to determine the differences in science process skill abilities of females and males in grade five, seven, and nine. An additional separate two-way multivariate analysis of variance (grade x gender) was also used to determine the differences in science attitudes of males and females in grade five, seven, and nine. A separate analysis of variance (PPSEX [parent's gender]) with the effects being parents' gender was used to determine differences in parents' levels of expectation for their childrens' performance in science. An additional separate analysis of variance (SSEX [student's gender]) with the effects being the gender of the student was also used to determine differences in parents' levels of expectation for their childrens' performance in science. Results of the analyses indicated significant main effects for grade level (p < .001) and gender (p < .001) on the TIPS II. There was no significant grade by gender interaction on the TIPS II. Results for the TOSRA also indicated a significant main effect for grade (p < .001) and the interaction of grade by sex ( p < .001). On variable ATT 5

    Alcohol use and involvement in school violent victimization are two significant public health problems among Hispanic youth. The present study examined alcohol use by involvement in school violent victimization among seventh through twelfth grade Hispanic students in one metropolitan area. The Pride Student National Survey was administered to students in their school classrooms. Results indicated that Hispanic students who were involved in school violent victimization were at increased risk for recent alcohol use and frequent episodic heavy drinking compared to Hispanic students who were not involved. Logistic regression revealed Hispanic males, junior high school, and high school students were at increased odds for recent alcohol use based on involvement in school violent victimization. Regarding frequent episodic heavy drinking, Hispanic males, females, and high school students were at increased odds. These findings can aid professionals in developing effective prevention programs and efforts for this high-risk population. Recommendations for future studies are included.

    The regulatory framework of the official controls on food safety, the criteria and methods from the planning of interventions in the field of official control to the management of information flows, and the standards described in the operation manual of the local competent authorities drafted by the Lombardy Region (2011) were evaluated. A questionnaire consisting of n. 10 questions with multiple answers draft in partnership with EPAM (the Association of Provincial Public Retail and catering businesses in Milan) to n. 107 Food service establishments of Milan shows that 92% of managers approve the introduction of a grading system. The regulatory framework is planned to support the implementation of risk assignment, unfortunately the attribution of risk category of retail and catering businesses is still different among regions.

    Background The esophageal cancer is one of the most common and aggressive worldwide. Recently, the AJCC changed the staging system, considering, among others, the important role of the lymph node metastasis on the prognosis. Aim To discuss the applicability of different forms of lymph node staging in a western surgical center. Methods Four hundred eighty seven patients with esophageal cancer were enrolled. Three staging systems were evaluated, the 6th and the 7th AJCC editions and the Lymph Node Metastatic Ratio. Results The majority of the cases were squamous cell carcinoma. The mean lymph node sample was eight. Considering the survival, there was no significant difference between the patients when they were classified by the 7th AJCC edition. Analysis of the Lymph Node Metastatic Ratio, just on the group of patients with 0 to 25%, has shown significant difference (p=0,01). The 6th AJCC edition shows the major significant difference between among the classifications evaluated. Conclusion In this specific population, the 7th AJCC edition for esophageal cancer was not able to find differences in survival when just the lymph node analysis was considered. PMID:26176242

    Ensuring rabies vaccines are potent and effective is paramount in preventing transmission of this deadly disease and safeguarding public health. Efficacy of human and veterinary vaccines is ensured by evaluating relative potency estimates of the vaccine compared to a rabies reference standard using the National Institutes of Health (NIH) test. Reference vaccines are based on the International Standard for Rabies Vaccine provided by the World Health Organization (WHO). A comparison study was conducted to determine the relative potency of the 5th WHO, 6th WHO, and United States Department of Agriculture's (USDA) 08-14 reference standards using the NIH test. Results from the study demonstrate that the 6th WHO reference standard is approximately twice as potent as the 5th WHO reference when reconstituted to contain 1 IU per ml. Based on these results, the Center for Veterinary Biologics (CVB) doubled the reconstitution volume of USDA veterinary reference 08-14 from 13 ml to 26 ml, for an initial use dilution of 0.7 IU per ml for use by veterinary biologics manufacturers in the NIH test. This study emphasizes the importance of reference standard calibration for use in the National Institutes of Health test.

    The purpose of this quantitative study was to determine the effect of Thinking Maps on the achievement of 6th-grade social studies students in order to determine its effectiveness. The population of this study came from a suburban middle school in the state of Georgia. The quantitative data included a pretest and posttest. The study was designed to find (a) whether there is a significant difference between the mean posttest scores on the benchmark test of 6th-grade students who are taught with either Thinking Maps or traditional social studies methods, (b) whether there is a significant difference between the mean posttest scores on the benchmark test of 6th-grade male versus female social studies students, and (c) whether there is a significant interaction between 6th-grade students' type of social studies class and gender as to differentially affect their mean posttest scores on the benchmark test. To answer these questions, students' pretest and posttest were compared to determine if there was a statistically significant difference after Thinking Maps were implemented with the treatment group for 9 weeks. The results indicate that there was no significant difference in the test scores between the students who were taught with Thinking Maps and the students who were taught without Thinking Maps. However, the students taught with Thinking Maps had the higher adjusted posttest scores.

    Whitford, Melinda M.

    Science educational reforms have placed major emphasis on improving science classroom instruction and it is therefore vital to study opportunity-to-learn (OTL) variables related to student science learning experiences and teacher teaching practices. This study will identify relationships between OTL and student science achievement and will identify OTL predictors of students' attainment at various distinct achievement levels (low/intermediate/high/advanced). Specifically, the study (a) address limitations of previous studies by examining a large number of independent and control variables that may impact students' science achievement and (b) it will test hypotheses of structural relations to how the identified predictors and mediating factors impact on student achievement levels. The study will follow a multi-stage and integrated bottom-up and top-down approach to identify predictors of students' achievement levels on standardized tests using TIMSS 2011 dataset. Data mining or pattern recognition, a bottom-up approach will identify the most prevalent association patterns between different student achievement levels and variables related to student science learning experiences, teacher teaching practices and home and school environments. The second stage is a top-down approach, testing structural equation models of relations between the significant predictors and students' achievement levels according.

    Cavanaugh, Terence William

    This study provided an initial investigation into the use of repurposed content-rich entertainment videos (versus traditional educational videos) presented in either an active or passive educational setting. Eight classes of seventh grade general science students (n = 361) were randomly assigned to one of four video treatment groups: (1) repurposed content-rich entertainment video in a passive setting, (2) repurposed content-rich entertainment video in an active setting, (3) traditional educational video in a passive setting, and (4) traditional educational video in an active setting. The subject matter of the videos focused on basic chemistry, scientific method, and the nature of life. The repurposed content-rich entertainment groups watched a StarTrek the Next Generation episode, and the traditional educational video groups watched videos from NASA and the Understanding Science Corporation. Students completed a knowledge-based pretest and an initial attitude survey prior to the treatment. During the treatment, all participants watched the videos, discussed the science content, and answered directed questions. Active setting groups discussed and answered questions during the video, while the passive setting groups discussed and answered questions after the video. The treatment period lasted approximately 135 minutes. Immediately following treatment, participants received a knowledge-based posttest and an attitude survey. Three weeks after treatment, retention tests and follow-up surveys were administered. Test and survey data were analyzed using single factor and repeated measures ANOVA followed by post hoc tests. Significant gains (p < 0.05) in test scores were found for repurposed content-rich entertainment video over traditional educational video groups. No significant differences were found in test scores between the active and passive setting groups. When the variables were combined, additional effects were noted. Specifically, significant differences were

    The experiment was conducted for ninety days of feeding trial at Haramaya University, Ethiopia using twenty four yearling male Somali goats weighing 20.4 +/- 2.02 (mean +/- SD) with the objectives to evaluate the effect of supplementation of peanut cake and wheat bran mixture (3:1) on body weight (BW) gain and carcass characteristics of Somali goats. The experiment was arranged with six blocks and four treatments in a randomized complete block design. The treatments were ad libitum feeding of hay (T1, control) and supplementation with 200 g (T2), 300 g (T3) and 400 g (T4) peanut cake and wheat bran mixture on dry matter (DM) basis. Supplementation reduced (P < 0.001) hay DM intake, but increased (P < 0.001) total DM intake at 300 g DM (T3) and 400 g DM (T4) level of supplementation compared to the control treatment. Daily BW gain, final BW, empty BW, hot carcass weight and dressing percent were higher (P < 0.001) in the supplemented treatments. Goats on the medium (T3) level of supplementation had significantly heavier (P < 0.001) liver and more muscle deposition, whereas those on hay alone (T1) exhibited heavier bone, head as well as gut contents (P < 0.05). It was concluded that supplementation of Somali goats with the different levels of peanut cake and wheat bran mixture promoted BW gain, dressing percentage and increased the proportion of edible offals. Similarity between the different levels of supplementation used in this study with regard to BW and carcass characteristics favours the use of the low (T2) or medium (T3) level than the high (T4) level of supplementation.

    Faced with reduced levels of food, animals must adjust to the consequences of the shortfall in energy. We explored how C57BL/6 mice withdrew energy from different body tissues during three months of food restriction at graded levels up to 40% (calorie restriction: CR). We compared this to the response to equivalent levels of protein restriction (PR) without a shortfall in calories. Under CR there was a dynamic change in body mass over 30 days and thereafter it stabilized. The time to reach stability was independent of the level of restriction. At the end of three months whole body dissections revealed differential utilization of the different tissues. Adipose tissue depots were the most significantly utilized tissue, and provided 55.8 to 60.9% of the total released energy. In comparison, reductions in the sizes of structural tissues contributed between 29.8 and 38.7% of the energy. The balance was made up by relatively small changes in the vital organs. The components of the alimentary tract grew slightly under restriction, particularly the stomach, and this was associated with a parallel increase in assimilation efficiency of the food (averaging 1.73%). None of the changes under CR were recapitulated by equivalent levels of PR. PMID:26079539

    Neuropsychological tests generally require adjustments for years of education when determining the presence of neurocognitive impairment. However, evidence indicates that educational quality, as assessed with reading tests, may be a better reflection of educational attainment among African Americans. Thus, African Americans with poor educational quality may be incorrectly classified with neurocognitive impairment based on neuropsychological tests. We compared the accuracy of neuropsychological test scores standardized using reading grade-equivalent versus years of education in predicting neurocognitive impairment among a sample of Whites and African-American adults who were HIV+. Participants were examined by a neurologist and classified with or without HIV-associated neurocognitive disorders according to accepted criteria. Participants were also classified as impaired versus not impaired based on their neuropsychological test scores standardized by 1) self-reported education or 2) WRAT-3 reading grade-level. Cross tabulation tables were used to determine agreement of the two methods in detecting impairment. Among African-Americans, standardized scores derived from reading scores had greater specificity than those derived from years of education (84.1% vs. 77.3). Among the Whites, correction based on years of education had both greater specificity and sensitivity. The results suggest that reading tests may be a useful alternative for determining NCI among African Americans.

  1. A correlation between selenium and carnitine levels with hypo-osmotic swelling test for sperm membrane in low-grade varicocele patients

    OBJECTIVE The hypo-osmotic swelling (HOS) test predicts membrane integrity by determining the ability of the sperm membrane to maintain equilibrium between the sperm cell and its environment. The aim of our study was to determine the correlation between selenium and carnitine levels in the seminal fluid with HOS test for sperm membrane in low-grade varicocele patients. PATIENTS AND METHODS Study numbered 64 examinees who suffered from low-grade varicocele and were divided into two groups, according to fertility potential and HOS test outcome. The study also included a control group of 64 healthy subjects, with no varicocele. RESULTS From the Shapiro-Wilk’s test, it is clear that carnitine distribution differs significantly from normal (0.938, p = 0.03). In distribution of selenium, Kolmogorov-Smirnov test clearly shows statistically significant deviation from the normal curve (z = 0.225, p < 0.000), likewise Shapiro-Wilk’s statistic (0.787, p < 0.000). According to the results, the second group had significantly higher levels of carnitine and selenium than the first group of examinees (p < 0.05); therefore, when we compared epididymal markers with HOS tests outcomes, we found significant differences between the two groups. There were no significant differences between second group and healthy subjects (p > 0.05). CONCLUSIONS HOS test outcome in varicocele patients is directly proportional to the carnitine and selenium levels, which could play a major role in both determining fertility parameters and in the treatment of its impairment. This result is important for sub-clinical varicocele in infertile patients with normal semen analysis, since there is no evidence of benefit from any treatment so far. PMID:26957259

    Juvenile osteochondritis dissecans (OCD) of the knee is a nosological entity acquired, idiopathic and potentially reversible. Dissects the subchondral bone tissue plane from the underlying bone, making a partial or complete osteochondral detachment, with a loose body. Consensus to treat none surgically poor symptomatic and stable lesions. If the lesion becomes instable or more symptomatic, surgical treatment will be best the option. Recently histological evidence holds is possible find sources of instability in deep layers sub chondral bone, even in patients with ¨stables lesions¨. This condition might be the reason of unfavorable evolution certain cases previously considered as ¨stable or incipient¨, treated with the classic non operative protocols. Objectives: The purpose of the present study consist in present a series of cases of young patients with symptomatic low grade juvenile OCD (grade I-II), treated surgically with subchondral debridement and fixation ¨in situ¨ describing the clinical and imaging findings. Methods: We evaluated 15 cases of symptomatic juvenile OCD of the knee, stables lesion (grade I/ II) according to Di Paola´s classification, who have not responded to conservative therapy for at least 6 months. Results: All patients were treated surgical consecutively with arthroscopically assisted ¨in situ¨ fixation with pins Smart Nail NR, ConMed-Linvatex and for the same group of surgeons. We evaluated the clinical and imagenologic outcomes with MRI for a minimum follow up of six month to one year. No looseness of fastening material or loose bodies in the submitted sample were recorded. The study by MRI imaging techniques using high definition chondral identification evidence allowed the consolidation of the fragment to the 6th month. Conclusion: All patients evolved asymptomatic and returned to the previous activity, with high level of satisfaction.

    The prevalence of child obesity in the Czech Republic has increased in the last several years, especially among school-aged children. While obesity trends are closely monitored in the Czech Republic, very little is known about the dietary habits and exercise behaviors of Czech children. The purpose of this study was to evaluate nutrient intakes and physical activity, as well as identify predictors of BMI-for-age in a sample of Czech school-aged children. Ninety-seven fourth, fifth and sixth graders and their parents from two large Czech cities participated in the study. Two 24-hour recalls provided total amount of energy, fat, percentage of energy derived from fat, dietary fiber, and servings of fruits and vegetables. Physical activity was measured by the Self-administered Physical Activity Checklist (SAPAC). Children consumed less energy and dietary fiber than suggested by Czech dietary recommendations. The proportion of energy that children consumed from fat was 28.5%. Children consumed 1.4 cups of fruit and 1.2 cups of vegetables. Children's physical activity levels fell within the current recommendations. Age was the only significant predictor of higher BMI-for-age. Poor dietary quality may be responsible for increasing rates of child obesity in the Czech Republic. Nutritional professionals in the Czech Republic should focus on increasing consumption of fruits, vegetables, and other high-fiber foods in order to reduce the risk for overweight among Czech children.

    Thiocyanate concentrations of serum, liver, kidney, spleen and longissimus dorsi were determined in 64 growing Large White x Landrace pigs offered 8 experimental isocaloric diets containing different levels of cassava peel and crude protein. Cassava peel increased serum thiocyanate on day 60 (P less than 0.01) and day 90 (P less than 0.01) of the trial, while the crude protein level increased it (P less than 0.05) on days 30 and 90, respectively. Interaction of the two factors was significant on day 30 (P less than 0.05) and day 90 (P less than 0.05). There was a correlation between cyanide intake and serum thiocyanate level. Coefficient of determination revealed that cyanide alone accounted for 28.5; 60.6 and 48.8% variation in serum thiocyanate on days 30, 60 and 90, respectively. Liver, spleen and longissimus dorsi thiocyanate were affected by dietary protein intake (P less than 0.05). Thiocyanate concentration was higher (P less than 0.05) on cassava peel diet. Generally, crude protein at 5% reduced organ and muscle thiocyanate concentrations. A diet containing 112.2-117.3 mg/kg hydrocyanic acid (HCN) affected serum but not organ and muscle thiocyanate in protein-sufficient diets.

However, even as the district implemented a constrained curriculum strategy, mathematics achievement growth between 6th sixth and 10th grade slowed and the achievement advantages associated with 8th eighth grade Algebra declined. Conclusions/Recommendations Our analyses suggest that curricular intensification increased the inclusiveness and decreased the selectivity of the mathematics tracking regime in Towering Pines middle schools. However, the findings suggest that this constrained curriculum strategy may have may have unintended negative consequences for student achievement. PMID:26120219

    Nineteen new archeointensity results were obtained from the analysis of groups of French pottery fragments dated to the Early Middle Ages (6th to 10th centuries AD). They are from several medieval ceramic production sites, excavated mainly in Saran (Central France), and their precise dating was established based on typo-chronological characteristics. Intensity measurements were performed using the Triaxe protocol, which takes into account the effects on the intensity determinations of both thermoremanent magnetization anisotropy and cooling rate. Intensity analyses were also carried out on modern pottery produced at Saran during an experimental firing. The results show very good agreement with the geomagnetic field intensity directly measured inside and around the kiln, thus reasserting the reliability of the Triaxe protocol and the relevance of the quality criteria used. They further demonstrate the potential of the Saran pottery production for archeomagnetism. The new archeointensity results allow a precise and coherent description of the geomagnetic field intensity variations in Western Europe during the Early Medieval period, which was until now poorly documented. They show a significant increase in intensity during the 6th century AD, high intensity values from the 7th to the 9th century, with a minimum of small amplitude at the transition between the 7th and the 8th centuries and finally an important decrease until the beginning of the 11th century. Together with published intensity results available within a radius of 700 km around Paris, the new data were used to compute a master curve of the Western European geomagnetic intensity variations over the past 1500 years. This curve clearly exhibits five intensity maxima: at the transition between the 6th and 7th century AD, at the middle of the 9th century, during the 12th century, in the second part of the 14th century and at the very beginning of the 17th century AD. Some of these peaks are smoothed, or

    Animals have to adjust their activities when faced with caloric restriction (CR) to deal with reduced energy intake. If CR is pronounced, allostasis can push individuals into alternate physiological states which can result in important health benefits across a wide range of taxa. Here we developed a new approach to determine the changes in behavioural phenotype associated with different levels of CR. We exposed C57BL/6 male mice to graded CR (from 0 to 40%) for three months and defined their behavioural phenotype using hidden Markov models of their movement and body temperature. All 40% CR mice exhibited a state-shift in behavioural phenotype and only some exposed to 30% CR did. We show for the first time that mice changed their activity characteristics rather than changed their activities. This new phenotyping approach provides an avenue to determine the mechanisms linking CR to healthspan. PMID:26306002

  8. [Grading the level of suspicion in criminal proceedings, restrictions of the proportionality principle and veto options in forensic autopsies].

    The article deals with two topics: determination of the necessary level of suspicion for an internal post-mortem examination pursuant to Section 87 (German) Code of Criminal Procedure and options of the family to object to the forensic autopsy. The level of suspicion required in this case is to be regarded as very low, even below that of the initial suspicion, because a detailed opinion as to any third-party fault can only be given after completion of the autopsy. The individual concerned does not have a right to oppose a forensic autopsy while still alive. The same applies to the family. Other than in clinical autopsies, the interest in prosecution is to be considered the higher good to be protected, because at the time of deciding a homicide cannot be ruled out and only an internal examination can furnish the necessary evidence. Consequently, it is appropriate. Contrary to the opinion often expressed in the literature, one cannot infer from the provisions of Sections 87 subs. 4, 33 subs. 3 Code of Criminal Procedure and Section 103 subs. 3 Basic Law that the family of the deceased has a right to be informed or heard. This can only be changed by the legislator in an amendment to the autopsy law.

  9. A comparison of the oral and silent reading methods of standardized science test delivery on the performance level of fifth-grade African American students

    Merenda, Gloria Louise

    This study compared two methods of standardized test administration, oral delivery using an audio tape and the standard silent reading by the student, on the performance level (test score) and science understanding (right answer/right reason) of urban fifth grade African American students. The effect of reading ability, special needs, and socioeconomic status were also examined as possible confounding variables. A randomized post-test only control group design was used with data for the sample (N = 106) collected from student files at two Detroit Public Schools, which included the Michigan Education Assessment Program (MEAP) reading and science scores. In addition, face-to-face interviews were completed with a small subsample to determine reasoning for selecting their answers. Six hypotheses were developed to determine if there were significant differences in science performance level and understanding in fifth grade urban African American students when the standardized science test, MEAP, Area Specific Portions, Physical Science and Earth/Space Science, were delivered orally, using the audio tape, and silently, which is the present standard delivery method. Significant differences in scores were found favoring the oral over the silent test group. A significant association was also found for reading and science MEAP scores, with students who had higher scores on the reading test achieving higher scores on the science test. Although socioeconomic status did not appear to result in differential outcomes among the students, a significant interaction was found between test administration type and socioeconomic status. The conclusion that was reached was that students who have difficulty in reading the printed material could benefit from having standardized tests administered orally (except for reading tests).

  10. Gender and grade level differences in interest, perceived personal capacity, and involvement in technology and engineering-related activities

    Weber, Katherine

    Society has become increasingly technological, demanding that all citizens have a level of technological literacy. In order for this to occur, both males and females must participate in technology-related activities to achieve an adequate level of technological literacy. Despite individual and organizational efforts, females continue to be underrepresented in STEM-related occupations. This is especially true in many engineering-related fields. Jolly, Campbell and Perlman (2004) devised the Engagement, Capacity, and Continuity (ECC) Trilogy. With each factor of the trilogy in place, Jolly et al. found that female representation increased in STEM. The purpose of this study was to identify whether Jolly, Campbell, and Perlman's (2004) Engagement, Capacity, and Continuity Trilogy could be utilized by teachers in technology and engineering program settings to examine their students' interest (engagement), perceived personal capacity (capacity), as well as participation in technology and engineering-related activities (continuity). This descriptive study surveyed 556 female and male middle school and high school students enrolled in Technology and Engineering classes. The results of this study revealed that when students indicated a high interest and a high perceived personal capacity, and when they participated in technology and engineering-related activities, they also indicated an interest in pursuing a career in engineering. The results also revealed that the male students continued to be encouraged by technology and engineering teachers, parents, and counselors to pursue a career in engineering more than female students. This startling finding should draw some concern; both males and females should be equally encouraged to consider engineering as a career. Technology and engineering teachers should implement activities that appeal to both males and females. Parents should encourage their daughters to participate in informal learning opportunities to nurture their

    In December 1987, Nebraska was selected by the Central Interstate Compact (CIC) Commission as the host state for the construction of a low-level radioactive waste disposal facility. After spending a year in the site screening process, the Compact`s developer, US Ecology, selected three sites for detailed site characterization. These sites were located in Nemaha, Nuckolls and Boyd Counties. One year later the Boyd County site was selected as the preferred site and additional site characterization studies were undertaken. On July 29, 1990, US Ecology submitted a license application to the Nebraska Department of Environmental Control (now Department of Environmental Quality-NDEQ). This paper will present issues that the NDEQ has dealt with since Nebraska`s selection as the host state for the CIC facility.

    The International Diabetes Federation predicts that, over the next twenty years, the largest increase in the prevalence of diabetes will be in the Africa region. Recognizing an unmet need for more focus on Africa and engagement with African scholars, the Islet Society held its 6th annual meeting July 20-21, 2014 in Stellenbosch, South Africa. Here, we present a report that covers the presentations and discussion points from that meeting. Work was presented on a variety of topics and included presentations by a significant proportion of Africa diabetes researchers. Overall, it was an excellent conference, with many new international collaborations initiated. We hope that other groups will also respond to the need for more conferences in Africa and focused on Africa.

    Proinflammatory cytokines that are produced by helper T cells (Th) regulate immune reactions, facilitate class switching of B cells, and prolong the lifespan of B and T cells. Eradication therapy using antibiotics is sometimes effective against gastrointestinal (GI) malignant lymphoma, suggesting that the tumor development or progression is affected by the inflammatory microenvironment. In the present study, serum samples from 148 patients with various subtypes of malignant lymphoma were tested for 11 proinflammatory Th1/Th2 cytokines. In the comparison by subtype or GI lesions, serum interleukin (IL)-8 (P = 6.7E-05), IL-4 (P = 7.5E-05), and IL-1β (P = 0.0043) levels showed significant differences among subtypes, being particularly elevated in follicular lymphomas (FL) and mucosa-associated lymphoid tissue (MALT) lymphomas. Serum IL-8 levels were elevated in GI-FL and MALT lymphomas, and serum IL-4 and IL-1 β levels were elevated in MALT lymphomas. These findings show that GI low-grade B-cell lymphoma could develop against the background of an inflammatory microenvironment. Thus, these cytokines may be useful as diagnostic markers and could provide new insights into tumor development.

    Twelve Hereford cows and four mature, ruminally cannulated Hereford x Angus heifers were fed supplements providing either 0 (control), 1, 2, or 3 kg/d of soybean hulls and including 440 g of protein/d (cottonseed meal was used to equalize protein intake) to determine the effects of supplementation on intake and utilization of low-quality native grass hay. Cattle were housed in individual pens and fed coarsely chopped (5-cm screen) native grass hay harvested in mid-November (4.1% CP, 76.9% NDF). Hay OM intake peaked (quadratic, P = .04) at 10.1 kg/d with 1 kg of soybean hulls and decreased when 2 kg (9.8 kg/d) or 3 kg (9.1 kg/d) of soybean hulls were fed. Although hay intake decreased when soybean hulls replaced cottonseed meal, feeding 3 kg soybean hulls decreased hay OM intake by only .64 kg. Total OM digestibility increased linearly (P = .009) with added increments of soybean hulls (45.8%, 46.2%, 46.6% and 48.6% for 0 through 3 kg soybean hulls/d, respectively), indicating that hulls were more digestible than the hay. Digestibility of NDF was not affected (P = .14) by level of soybean hull supplementation, although ADF digestibility increased (linear, P = .03). Increases in OM intake and digestibility with soybean hulls combined to increase digestible OM intake (linear, P = .0001). Soybean hull supplementation increased ruminal VFA concentrations (linear, P = .04) and the molar proportion of propionate (linear, P = .006).(ABSTRACT TRUNCATED AT 250 WORDS)

    From the 58 papers published in 2012 in Fluid Dynamics Research, the following paper has been selected for the sixth FDR prize: The finite-difference lattice Boltzmann method and its application in computational aero-acoustics by Michihisa Tsutahara (Professor Emeritus, Kobe University, Japan), published in volume 44 (August 2012) 045507. This is a review paper of the author's recent work on the finite-difference lattice Boltzmann method (FDLBM). In this paper, the author introduces a modified FDLBM and its application to aero-acoustics. To solve the discrete Bhatnager, Gross and Krook equation for simulating fluid flow, the FDLBM applies a stable finite-difference scheme on a curvilinear coordinate system, whereas the ordinary lattice Boltzmann method uses regular lattices. It is known that for the lattice Boltzmann methods, there is difficulty in simulating high Mach number compressible flows in principle. To alleviate this, the author proposed the modified FDLBM, expanding the flexibility of setting time increments. With this FDLBM, the author has shown that it is possible to simulate compressible flows efficiently around complex bluff bodies and with complex aero-acoustic behaviour. The author summarizes all those works, including studies only available in Japanese up to now, in this review paper. After discussing the details of the FDLBM proposed by the author, example results of simulating the Aeolian tone generated from a circular cylinder at the Mach number M = 0.7 are shown. Then, the scheme is expanded for moving bodies by combining with the Arbitrary Lagrangian Eulerian formulation. Using this moving mesh scheme, the author shows the simulation results of the very strong sound pressure generated by a high-speed train in a tunnel. For issues of sound propagation in compressible two-phase flows whose density ratio is high, the two-particle model is introduced. Also, techniques to reduce noise generation from the flow velocity and pressure at gas-liquid interfaces are shown. Finally, the scattering of sound waves by water droplets is discussed. In thick fog, the sound coming from a distance becomes faint due to the sound-scattering effects of micro water droplets. The author gives an example of successfully solving such an issue by the FDLBM. It is highly admirable that the author developed the new FDLBM for aero-acoustic issues and has summarized it with sub-schemes to overcome several difficulties of engineering aeroacoustics in this review. It will certainly contribute to further development of fluid dynamics through computational aero-acoustics. Consequently, this paper was selected as the winner of the sixth FDR prize.

    OBJECTIVE. Clinical implications of serum anti-Helicobacter pylori immunoglobulin G (IgG) titer were unclear. This study investigated the associations of serum anti-H. pylori IgG titer with grade of histological gastritis, mucosal bacterial density and levels of serum biomarkers, including pepsinogen (PG) I, PGII, PGI/II ratio and gastrin-17. MATERIAL AND METHODS. Study participants were from a screening program in northern China. Serum anti-H. pylori IgG measurements were available for 5922 patients with superficial gastritis. Serum anti-H. pylori IgG titer and serum biomarkers were measured using ELISA, and gastric biopsies were evaluated using standardized criteria. RESULTS. In patients with mild, moderate or severe superficial gastritis, the mean serum anti-H. pylori IgG titers were 17.3, 33.4 and 54.4 EIU (p for trend < 0.0001), respectively. As mucosal H. pylori density score increased from 0 to 3, the mean serum anti-H. pylori IgG titers also increased from 24.7 to 44.8 EIU (p for trend < 0.0001). Serum anti-H. pylori IgG titer was associated positively with serum PGI, PGII and gastrin-17 concentrations and negatively with PGI/II ratio, and the association was the strongest for PGII. The mean PGII concentration of the patients in the highest quartile of IgG titer was twice the mean concentration of the patients in the lowest quartile (17.2 vs. 8.6 EIU, p < 0.0001). CONCLUSIONS. Our results suggest that serum anti-H. pylori IgG titer was associated positively with grade of histological gastritis, mucosal bacterial density and concentrations of serum PGI, PGII and gastrin-17, and negatively with PGI/II ratio.

    With supplemental funding from the National Science Foundation (NSF), students from the University of Delaware's Science Semester course took part in a two-day research cruise in the Delaware Bay Estuary. The Science Semester, an NSF-funded project, is an integrated 15-credit sequence that encompasses the entire course work for the spring semester for approximately 60 sophomore-level elementary education majors. The semester includes the earth, life, and physical science content courses and the education science methods course integrated into one curriculum. In this curriculum, problem-based learning and other inquiry-based approaches are applied to foster integrated understandings of science and pedagogy that future elementary teachers need to effectively use inquiry-based approaches in their classrooms. The research cruise was conducted as part of one of the four major investigations during the course. The investigation focused on Delaware's state marine animal, Limulus polyphemus. It is one of the four remaining species of horseshoe crabs; the largest spawning population of Limulus is found in Delaware Bay. Within the problem- and inquiry-based learning approaches of the Science Semester course, the students became aware that very little data exists on the benthic habitat of Limulus polyphemus. In order to learn more about this habitat, a cohort of seven students from the course was recruited as part of the scientific party to take part in the research cruise to collect data on the floor of Delaware Bay. The data included: multibeam bathymetry/backscatter data, grab samples of bay bottom sediments, and CTD profiles. Prior to the cruise, all students in the course took part in laboratory exercises to learn about topographic maps and navigation charts using the Delaware Bay area as the region of study. While "at-sea", the cruise participants sent the ship's latitude and longitude positions as a function of time. The positions were used by the on-land students to

    Women persistently infected with human papillomavirus (HPV) type 16 are at high risk for development of cervical intraepithelial neoplasia grade 3 or cervical cancer (CIN3+). We aimed to identify biomarkers for progression to CIN3+ in women with persistent HPV16 infection. In this prospective study, 11,088 women aged 20-29 years were enrolled during 1991-1993, and re-invited for a second visit two years later. Cervical cytology samples obtained at both visits were tested for HPV DNA by Hybrid Capture 2 (HC2), and HC2-positive samples were genotyped by INNO-LiPA. The cohort was followed for up to 19 years via a national pathology register. To identify markers for progression to CIN3+, we performed microarray analysis on RNA extracted from cervical swabs of 30 women with persistent HPV16-infection and 11 HPV-negative women. Six genes were selected and validated by quantitative PCR. Three genes were subsequently validated within a different and large group of women from the same cohort. Secondly, Kaplan-Meier and Cox-regression analyses were used to investigate whether expression levels of those three genes predict progression to CIN3+. We found that high transcript levels of TMEM45A, SERPINB5 and p16INK4a at baseline were associated with increased risk of CIN3+ during follow-up. The hazard ratios of CIN3+ per 10-fold increase in baseline expression level were 1.6 (95% CI: 1.1-2.3) for TMEM45A, 1.6 (95% CI: 1.1-2.5) for p16INK4a, and 1.8 (95% CI: 1.2-2.7) for SERPINB5. In conclusion, high mRNA expression levels of TMEM45A, SERPINB5 and p16INK4a were associated with increased risk of CIN3+ in persistently HPV16-infected women. PMID:27508094

    Sullivan, Sandra Judd

    The purpose of this study was to determine if a math, science, and technology intervention program improved grade school girls' attitudes and stereotypes toward science and scientists, as well as participation levels in science-related activities, two years after their participating in the program. The intervention program evaluated was Operation SMART, developed by Girls Incorporated. Participants were recruited from the 6th and 7th grades from two public middle schools in Northern California. One hundred twenty-seven girls signed up for the survey and were assigned to either the SMART group (previous SMART participants) or Non-SMART group (no previous experience with SMART). The survey consisted of five parts: (1) a background information sheet, (2) the Modified Attitudes Toward Science Inventory, (3) the What Do You Do? survey, (4) the Draw-A-Scientist Test-Revised, and (5) a career interests and role models/influencer survey. Results indicated that there were no significant differences between the SMART and Non-SMART groups on any of the test measures. However, middle school attended did have a significant effect on the outcome variables. Girls from Middle School A reported more positive attitudes toward science, while girls from Middle School B reported higher participation levels in extracurricular science activities. Possible explanations for these findings suggest too much time had passed between treatment effect and time of measurement as well as the strong influence of teacher and school environment on girls' attitudes and stereotypes. Recommendations for future research are discussed.

    The strong seismological potential of the Central Apennines, including the L'Aquila basin, is documented in the historical heritage of the past two millenia and by paleoseismological data. Despite the main active fault system network of Central Italy is well described and mapped, the April 6th 2009 L'Aquila event showed that Mw> 6.0 earthquakes can occur on fault zones characterized by subtlemorphotectonic evidence, like the Paganica Fault, whose seismic hazard potential may thus be overlooked. An additional source of uncertainty is provided by the evidence that in the L'Aquila region many active extensional fault systems developed by negative inversion of pre-existing contractional deformation structures. The resulting complex along-strike segmentation and overlap patterns are thus governed by the interplay between the modern extensional stress field and the structural inheritance and reduce the effectiveness of predictive scaling laws, which do not typically account for fault attributes produced by polyphased tectonics. This is particularly true in the L'Aquila region, where seismic activation of the northwestern half of the basin-boundary fault system has been proposed for the 1703 Mw ~ 7.0 earthquake, whereas only the central segment was activated in 1461 and 2009, producing earthquakes with Mw ~ 6.0 - 6.3. The reasons for this dual behaviour are still unclear despite many structural and paleoseismological studies. Indirect evidence for paleoearthquake magnitude from ground shaking effects, like paleo-fluidization structures, can provide very useful complementary information on maximum expected earthquake intensities along active fault systems.In this work wedescribe in detail large paleo-fluidization-induced features associated with a previously unmapped extensional fault zone cutting through Quaternary strata. These sediments, including lacustrine lignites and mudstones, show a somehow enigmatic overconsolidation that we quantitatively describe, as well as

  11. Effects of tactual and kinesthetic instructional resources on simple recall and higher-level cognitive science achievement and attitudes toward science of third-grade suburban students

    Searson, Robert Francis

    This researcher investigated the effects of tactual and kinesthetic instructional resources on the simple recall and higher-level cognitive science achievement and attitudes toward science of third-grade suburban students in a northern New Jersey school district. The Learning Style Inventory (LSI) (Dunn, Dunn, & Price, 1996) was administered to ascertain the identity of the learning-style perceptual preferences of all 59 third-graders who completed the three science units. Each of the three classes was presented two science units using learning-style instructional resources; one science unit was taught using traditional methods. All three science units were completed in a six-week period. Students were administered a pretest and posttest for each science unit and the Semantic Differential Scale (Pizzo, 1981) at the conclusion of each science unit. Analysis of variance (ANOVA) assessed the effects of treatments and attitudes toward science. The statistical analysis of this study revealed a significant difference (p < 0.0001) between students' simple recall science achievement posttest scores when taught tactually and/or kinesthetically compared to when they were taught science traditionally. Furthermore, the Contingency Table analysis, using Fisher's Exact Test indicated a significant difference (p = 0.00008) between the higher-level cognitive science achievement posttest scores when students are taught science tactually and/or kinesthetically compared to when they are taught science traditionally. The findings of this study supported the view when tactual and/or kinesthetic methods were employed, higher achievement gains were realized for simple recall and higher-level cognitive science achievement. Further recommendations called for a reexamination of science instructional methods employed in our elementary classroom.

    Our aim was to study the association of two potential serum biomarkers glial fibrillary acidic protein (GFAP) and epidermal growth factor receptor (EGFR) with prognostic markers such as IDH1 mutation, tumor burden, and survival in patients with high-grade gliomas (HGG). Additionally, our objective was to evaluate the potential of serum EGFR as a surrogate marker for EGFR status in the tumor. Pre-operative serum samples were prospectively collected from patients with primary (n = 17) or recurrent (n = 10) HGG. Serum GFAP and EGFR levels were determined by ELISA and studied for correlation with molecular markers including EGFR amplification, tumor volume in contrast-enhanced T1-weighted MRI, and progression-free survival (PFS). Pre-operative serum GFAP level of ≥0.014 ng/ml was 86 % sensitive and 85 % specific for the diagnosis of glioblastoma. High GFAP was related to the lack of IDH1 mutation (P = 0.016), high Ki67 proliferation index (P < 0.001), and poor PFS (HR 5.9, CI 1.2-29.9, P = 0.032). Serum GFAP correlated with enhancing tumor volume in primary (r = 0.64 P = 0.005), but also in recurrent HGGs (r = 0.76 P = 0.011). In contrast, serum EGFR levels did not differ between HGG patients and 13 healthy controls, and were not related to EGFR status in the tumor. We conclude that high serum GFAP associates with IDH1 mutation-negative HGG, and poor PFS. Correlation with tumor burden in recurrent HGG implicates the potential of serum GFAP for detection of tumor recurrence. Our results suggest that circulating EGFR is not derived from glioma cells and cannot be used as a marker for EGFR status in the tumor.

    We evaluated frontal brain activation during a mixed attentional/working memory task with graded levels of difficulty in a group of 19 healthy subjects, by means of time-domain functional near-infrared spectroscopy (fNIRS). Brain activation was assessed, and load-related oxy- and deoxy-hemoglobin changes were studied. Generalized linear model (GLM) was applied to the data to explore the metabolic processes occurring during the mental effort and, possibly, their involvement in short-term memorization. GLM was applied to the data twice: for modeling the task as a whole and for specifically investigating brain activation at each cognitive load. This twofold employment of GLM allowed (1) the extraction and isolation of different information from the same signals, obtained through the modeling of different cognitive categories (sustained attention and working memory), and (2) the evaluation of model fitness, by inspection and comparison of residuals (i.e., unmodeled part of the signal) obtained in the two different cases. Results attest to the presence of a persistent attentional-related metabolic activity, superimposed to a task-related mnemonic contribution. Some hemispherical differences have also been highlighted frontally: deoxy-hemoglobin changes manifested a strong right lateralization, whereas modifications in oxy- and total hemoglobin showed a medial localization. The present work successfully explored the capability of fNIRS to detect the two neurophysiological categories under investigation and distinguish their activation patterns.

    Corms such as wild cocoyam [Colocasia esculenta] have potential to replace maize as a cheaper energy source in poultry rations. A feeding trial was conducted to evaluate the effects of graded levels of fermented wild cocoyam [Colocasia esculenta (L.) Schott] corm (FWCC), as substitutes for maize in the diets of broilers at the starter phase. One hundred and twenty unsexed day-old Hybro broiler chicks were randomly distributed to four dietary treatments in a Completely Randomized Design (CRD). There were 3 replicates per dietary treatment with 10 birds per replicate. Diet 1 without FWCC served as the control. Diets 2, 3 and 4 contained 10, 20 and 30% FWCC. Each of the diets represented a treatment. The experimental diets and clean drinking water were supplied ad libitum for 4 weeks (28 days) representing the starter phase of the broiler production. Result of the performance revealed significant (p<0.05) differences in feed intake, weight gain and feed conversion ratio. The economic analysis also showed that cost (Naira58.52) of a kilogram feed was highest (p<0.05) for the control and least (Naira53.10) for 30% FWCC. The least cost (Naira101.24) of feed per kilogram weight gain (p<0.05) was obtained for birds fed 30% FWCC compared to (Naira105.53) for the control. It was concluded that maize can economically be substituted with 30% FWCC in broiler starter diets.

    Diets with graded levels of the experimental microbial phytase SP1002 (0, 500, 1000, 2000 and 4000 FTU/kg) were fed to juvenile Nile tilapia (average BW = 68.8 g) for 60 days (n = 4). A digestibility trial ran parallel to the growth trial using 0.3 g TiO2/100 g as an indigestible marker. The efficiency of phytase supplementation was evaluated by parameters of growth response, crude protein and mineral utilization (using body composition data), apparent nutrient digestibility, mineral content in scale and vertebra and inorganic phosphorus in blood plasma. Data were submitted to ANOVA and Tukey-test using SAS-program. Significant improvements (p < 0.01) were found for growth, FCR and SGR, mainly for diets with 1000 and 2000 FTU/kg phytase supplementation. Protein utilization was significantly increased and maximized between 1000 and 2000 FTU/kg. Phosphorus utilization increased significantly up to 4000 FTU/kg. Digestibility of protein and phosphorus was also significantly improved. Phosphorus concentration in the blood, vertebra and scale increased significantly after phytase addition. Similarly, calcium and magnesium concentration in vertebra and scale were increased. Generally, phytase supplementation between 1000 and 2000 FTU/kg resulted in growth rates and mineralization parameters similar to a control diet with inorganic phosphorus.

    There are rare times in astronomy when a celestial event, visible in broad daylight, can be used to measure a fundamental parameter and inspire a globe full of school age students. The June 5th/6th transit of Venus was one such event. In celebration, nine astronomy postdocs from the Chilean mainland traveled to Easter Island to lead a series of astronomy outreach activities over three days, culminating in a transit-viewing event. Our team dubbed "Equipo Hetu'u" or "Team Star" in the Rapa Nui (Easter Island native) language spent two days giving astronomy talks and doing hands-on demonstrations at the Museo Antropologico P. Sebastian Englert. In the final day-and-a-half leading up to the transit, we visited the science classes in the majority of the schools on the island, in order to spread the message about the once-in-a-lifetime transit event, highlighting how we planned on using it to measure the distance to the Sun. We estimate over 25% 1500 people) of this remote island participated in one or more of our organized activities. Our experience with this project is an excellent lesson on how to organize, lead, and fully execute a major outreach endeavor that inspires hundreds with minimal resources (save the spectacular event provided by the cosmos).

    The beginning of metallurgy in the ancient Near East attracts much attention. The southern Levant, with the rich assemblage of copper artifacts from the Nahal Mishmar cave and the unique gold rings of the Nahal Qanah cave, is regarded as a main center of early metallurgy during the second half of the 5th millennium CalBC. However, a recently discovered copper awl from a Middle Chalcolithic burial at Tel Tsaf, Jordan Valley, Israel, suggests that cast metal technology was introduced to the region as early as the late 6th millennium CalBC. This paper examines the chemical composition of this item and reviews its context. The results indicate that it was exported from a distant source, probably in the Caucasus, and that the location where it was found is indicative of the social status of the buried individual. This rare finding indicates that metallurgy was first defused to the southern Levant through exchange networks and only centuries later involved local production. This copper awl, the earliest metal artifact found in the southern Levant, indicates that the elaborate Late Chalcolithic metallurgy developed from a more ancient tradition. PMID:24671185

    Proteomics is at the epicenter of post-genomics biotechnologies that are currently driving the next generation system science. Moreover, proteomics is a truly global science. The 6(th) Annual Meeting of Proteomics Society, India (PSI) and International Conference on "Proteomics from Discovery to Function" held from December 7-9, 2014, was a transformative endeavor for global proteomics, bringing together the luminaries in the field of proteomics for the very first time in India. This meeting report presents the lessons learned and the highlights of this international scientific conference that was comprised of nine thematic sessions, pre- and post-conference workshops, and an opportunity to cultivate enduring collaborations for proteomics science to benefit both India and global society. The conference had an unforgettable impression on the participants: for the first time, India hosted past and present President and Council members from the Human Proteome Organization (HUPO), along with eminent scientists and young scholars from India and abroad in the field of proteomics at such a large scale, a major highlight of this international event. In all, the PSI 2014 was a milestone conference that has firmly poised the Indian life sciences community as a leading contributor to post-genomics life sciences, thus cultivating crucial trans-generational capacity and inspiration by recognizing the emerging scholars and omics systems scientists who can think and conduct science from cell to society.

    Several events of the seismic sequence started on 6th of April 2009, that struck the town of l'Aquila, Italy, have been recorded by an array of seismic stations, located approximately 90 km south-west of the epicenters. One of the stations is in a 80-m-deep borehole, installed since the early 2008 in the middle of the main sedimentary body of the city: the Tiber valley. This represents a unique opportunity to tune seismic simulations of the soil shaking due to a seismic sequence located in Central Apennines region. This latter is considered, with the Albani Hills one, the main seismogenic area responsible of the seismic hazard in the city. We have generated a 3D velocity model for a portion of the city (5 EW x 3 NS km2 wide, and 200 m deep, including topography) where the array is located. A viscoelastic wave propagation due to S-wave pulse of general polarization and given incidence is obtained by the 3D FD hybrid numerical modeling. The 3D pulse response and the borehole recording are then used to generate the complete 3D synthetics covering the area. The results are verified by comparing to the surface recordings and large ground motion amplifications data.

    The 6th of August 2012 eruption of Te Maari (Mt Tongariro, New Zealand) generated wet pyroclastic density currents (PDCs) which caused widespread dieback of vegetation (singed, brown foliage) in their path. An absence of significant charcoal formation suggests that PDC temperatures were mostly below 250 °C. Textural evidence for liquid water being present in the matrices during emplacement (vesicles) suggests that temperatures were < 100 °C. We determined a probable minimum PDC temperature using an experiment replicating the critical temperatures required to induce foliar browning in seven species affected by the eruption. In locations where all species exhibited browned foliage (or were defoliated), temperatures were probably ≥ 64 °C assuming a PDC duration of 60 s. In the more distal areas, where only the most susceptible species were browned while others remained healthy and unaffected, temperatures were probably around 51-58 °C. These results have relevance to volcanic hazard mitigation and risk assessment, especially on the popular Tongariro Alpine Crossing.

    One hundred fifty Anak and 120 Nigerian heavy local ecotype (NHLE) chickens were used to study the effects of feeding graded levels of mango seed kernel meal (MKM) replacing maize diet on growth traits and haematological parameters. A 2 × 5 factorial arrangement was employed: two breeds and five diets. The birds were randomly allocated to five finisher diets formulated such that MKM replaced maize at 0, 10, 20, 30 and 40% (T1, T2, T3, T4 and T5) inclusion levels, respectively. The effect of breed and dietary treatments on growth performance and blood characteristics were determined. The results showed a significant (P < 0.05) breed effect on body weight and gain, shank length, thigh length, body width and body length. The growth traits of Anak breed were found to be superior to NHLE chickens. Within treatments, chicks on T1, T2 and T3, grew heavier than those on T4 and T5. However, feed intake, feed conversion ratio (FCR) and haematological indices (RBC, Hb, MCV, MCH and MCHC count) were not significant (P > 0.05) when the breeds and treatments were compared. It was concluded that inclusion of dietary MKM below 30% could replace maize in the diets of Anak and NHLE growing chickens without adverse effect on growth performance and blood constituents. This work suggests that genetic differences exist in growth traits of these breeds of chickens. This advantage could be useful in breed improvement programmes and better feeding managements of the NHLE and Anak chickens.

    The effects of feeding graded levels of dried moringa (Moringa stenopetala) leaf on intake, body weight gain (BWG), digestibility and nitrogen utilization were studied using male sheep (BW of 13.8 ± 0.12 kg). Six sheep were randomly allocated to each of the four treatment diets: Rhodes grass (Chloris gayana) hay offered ad libitum (T1), hay + 150 g moringa leaf (T2), hay + 300 g moringa leaf (T3), hay + 450 g moringa leaf (T4) were offered daily. A 7-day digestibility trial and an 84-day growth experiments were conducted. Dry matter (DM), organic matter (OM) and crude protein (CP) intakes increased (P < 0.05) with increasing levels of moringa leaf in the diets. Sheep fed T2, T3 and T4 diets gained (P < 0.05) 40.2, 79.1 and 110.1 g/head/day, respectively, while the control group (T1) lost weight (-13.3 g/head/day). The apparent digestibilities of DM, OM, neutral detergent fibre and acid detergent fibre were similar (P > 0.05) among treatments. The digestibility of dietary CP increased (P < 0.05) with increasing levels of moringa leaf, but there was no significant difference between T2 and T3 diets. The nitrogen (N) intake and urinary N excretion increased (P < 0.05) with increasing levels of moringa leaf. The N retention was highest (P < 0.05) for 450 g moringa leaf supplementation. The control group was in a negative N balance. Supplementing a basal diet of Rhodes grass hay with dried moringa leaves improved DM intake, BWG and N retention. It is concluded that M. stenopetala can serve as a protein supplement to low-quality grass during the dry season under smallholder sheep production system.

    Nowadays, new advances in the use of cell free fetal DNA (cffDNA) in maternal plasma of pregnant women has provided the possibility of applying cffDNA in prenatal diagnosis as a non-invasive method. In contrary to the risks of invasive methods that affect both mother and fetus, applying cffDNA is proven to be highly effective with lower risk. One of the applications of prenatal diagnosis is fetal gender determination, which is important in fetuses at risk of sex-linked genetic diseases. In such cases by obtaining the basic information of the gender, necessary time management can be taken in therapeutic to significantly reduce the necessity of applying the invasive methods. Therefore in this study, the probability of detecting sequences on the human Y-chromosome in pregnant women has been evaluated to identify the gender of fetuses. Peripheral blood samples were obtained from 80 pregnant women with gestational age between 6th to 10th weeks and the fetal DNA was extracted from the plasma. Identification of SRY, DYS14 & DAZ sequences, which are not presentin the maternal genome, was performed using Real-Time PCR. All the obtained results were compared with the actual gender of the newborns to calculate the test accuracy. Considerable 97.3% sensitivity and 97.3% specificity were obtained in fetal gender determination which is significant in the first trimester of pregnancy. Only in one case, false positive result was obtained. Using non-invasive method of cffDNAs in the shortest time possible, as well as avoiding invasive tests for early determination of fetal gender, provides the opportunity of deciding and employing early treatment for fetuses at risk of genetic diseases.

    As a part of the 6th IWGT, an expert working group on the comet assay evaluated critical topics related to the use of the in vivo comet assay in regulatory genotoxicity testing. The areas covered were: identification of the domain of applicability and regulatory acceptance, identification of critical parameters of the protocol and attempts to standardize the assay, experience with combination and integration with other in vivo studies, demonstration of laboratory proficiency, sensitivity and power of the protocol used, use of different tissues, freezing of samples, and choice of appropriate measures of cytotoxicity. The standard protocol detects various types of DNA lesions but it does not detect all types of DNA damage. Modifications of the standard protocol may be used to detect additional types of specific DNA damage (e.g., cross-links, bulky adducts, oxidized bases). In addition, the working group identified critical parameters that should be carefully controlled and described in detail in every published study protocol. In vivo comet assay results are more reliable if they were obtained in laboratories that have demonstrated proficiency. This includes demonstration of adequate response to vehicle controls and an adequate response to a positive control for each tissue being examined. There was a general agreement that freezing of samples is an option but more data are needed in order to establish generally accepted protocols. With regard to tissue toxicity, the working group concluded that cytotoxicity could be a confounder of comet results. It is recommended to look at multiple parameters such as histopathological observations, organ-specific clinical chemistry as well as indicators of tissue inflammation to decide whether compound-specific toxicity might influence the result. The expert working group concluded that the alkaline in vivo comet assay is a mature test for the evaluation of genotoxicity and can be recommended to regulatory agencies for use.

    Energy is a sector of paramount importance over the coming decades if we are to ensure sustainable development that respects our environment. The research and development of novel approaches to convert available energy into usable forms using micro and nanotechnologies can contribute towards this goal and meet the growing need for power in small scale portable applications. The dominant power sources for handheld and other portable electronics are currently primary and rechargeable batteries. Their limited energy density and adverse effects on the environment upon disposal suggest that alternative approaches need to be explored. This special issue will showcase some of the leading work in this area, initially presented at PowerMEMS 2006, the 6th International Workshop on Micro and Nanotechnologies for Power Generation and Energy Conversion Applications. Power MEMS are defined as microsystems for electrical power generation and other energy conversion applications, including propulsion and cooling. The range of power MEMS technologies includes micro thermodynamic machines, such as microturbines, miniature internal combustion engines and micro-coolers; solid-state direct energy conversion, such as thermoelectric and photovoltaic microstructures; micro electrochemical devices, such as micro fuel cells and nanostructure batteries; vibration energy harvesting devices, such as piezoelectric, magnetic or electrostatic micro generators, as well as micro thrusters and rocket engines for propulsion. These can either be driven by scavenging thermal, mechanical or solar energy from the environment, or from a stored energy source, such as chemical fuel or radioactive material. The unique scope leads to unique challenges in the development of power MEMS, ranging from the integration of novel materials to the efficient small scale implementation of energy conversion principles. In this special issue, Mitcheson et al provide a comparative assessment of three inertial vibration

  11. Effect of graded levels of niacin supplementation of a semipurified diet on energy and nitrogen balance, growth performance, diarrhea occurrence, and niacin metabolite excretion by growing swine.

    Thirty-six crossbred barrows with an average initial age of 42 d and BW of 13.8 kg were placed in individual metabolism crates in a 35-d experiment to evaluate the supplementation of a semipurified diet with graded levels of crystalline niacin. Response criteria were energy and N balance, growth performance, occurrence of niacin deficiency diarrhea, and urinary excretion of the niacin metabolite N(1)-methyl-2-pyridone-5-carboxylamide (PYR). The basal diet met the true ileal Trp requirement of growing swine, and supplementation with 6, 10, 14, 18, 22, or 44 mg of niacin/kg made 6 treatments. Pigs were observed for scours twice daily, and pig BW and feed consumption were determined weekly. Total urine collections and fecal grab samples were made twice daily from each pig from d 28 to 35. Pigs fed the diet containing 14 mg of niacin/kg absorbed and retained more (P < 0.05) grams of N/d, had a greater N digestibility (%, P < 0.05), a greater ADFI and ADG (P < 0.10), and no diarrhea (P < 0.05) compared with pigs fed the diet containing 6 mg of niacin/kg, and pigs fed the diet containing 10 mg of niacin/kg were intermediate in ADG. There were no additional improvements in the response criteria with niacin supplementation greater than 14 mg/kg. Urinary PYR criteria (mg/L and mg/d) were greater (P < 0.001) for pigs fed the diet containing 44 mg of niacin/kg than for pigs fed the diets containing 6 to 22 mg of niacin/kg. However, urinary PYR criteria for pigs fed the diets containing 6 to 22 mg of niacin/kg did not differ from each other, indicating that PYR was not a sensitive indicator of niacin status for growing swine. Niacin treatment did not affect the percentages of N retained/N absorbed, N retained/N intake, DE, or ME. In conclusion, 14 mg of crystalline niacin/kg of semipurified diet adequate in Trp was the minimum concentration of niacin that maximized N utilization and growth performance, and prevented niacin deficiency diarrhea of growing swine in the current
