  2. Physiology of Escherichia coli K-12 During Conjugation: Altered Recipient Cell Functions Associated with Lethal Zygosis

    PubMed Central

    Skurray, Ronald A.; Reeves, Peter

    1973-01-01

    The number of viable F− cells decreases when Escherichia coli recipient cells are mixed with an excess of Hfr cells. Evidence is presented showing that lethal zygosis was accompanied by changes in the physiology of the recipient cells, including (i) inhibition of deoxyribonucleic acid synthesis, (ii) inhibition of β-galactosidase induction, (iii) altered transport and accumulation of galactosides, and (iv) leakage of β-galactosidase into the supernatant fluid. The results are discussed in terms of possible conjugation-associated changes that, at high Hfr to F− ratios, lead to lethal zygosis. PMID:4572705

  9. Creating Effective K-12 Outreach

    NASA Astrophysics Data System (ADS)

    Hopkins, J.

    2011-12-01

    Grant opportunities require investigators to provide 'broader impacts' for their scientific research. For most researchers this involves some kind of educational outreach for the K-12 community. I have been able to participate in many different types of grant funded science teacher professional development programs. The most valuable have been outreach where the research seamlessly integrated with my classroom curriculum and was sustainable with my future classes. To accomplish these types of programs, the investigators needed to research the K-12 community and identify several key aspects of the K-12 environment where their expertise would benefit me and my students. There are a lot of different K-12 learning environments, so researchers need to be sure to match up with the right grade level and administrative environment. You might want to consider non-main stream school settings, such as magnet programs, STEM academies, and distance learning. The goal is to try to make your outreach seem natural and productive. This presentation will illustrate how researchers can create an educational outreach project that will be a win-win situation for everyone involved.

  13. Streptococcus salivarius K12 Limits Group B Streptococcus Vaginal Colonization.

    PubMed

    Patras, Kathryn A; Wescombe, Philip A; Rösler, Berenice; Hale, John D; Tagg, John R; Doran, Kelly S

    2015-09-01

    Streptococcus agalactiae (group B streptococcus [GBS]) colonizes the rectovaginal tract in 20% to 30% of women and during pregnancy can be transmitted to the newborn, causing severe invasive disease. Current routine screening and antibiotic prophylaxis have fallen short of complete prevention of GBS transmission, and GBS remains a leading cause of neonatal infection. We have investigated the ability of Streptococcus salivarius, a predominant member of the native human oral microbiota, to control GBS colonization. Comparison of the antibacterial activities of multiple S. salivarius strains by use of a deferred-antagonism test showed that S. salivarius strain K12 exhibited the broadest spectrum of activity against GBS. K12 effectively inhibited all GBS strains tested, including disease-implicated isolates from newborns and colonizing isolates from the vaginal tract of pregnant women. Inhibition was dependent on the presence of megaplasmid pSsal-K12, which encodes the bacteriocins salivaricin A and salivaricin B; however, in coculture experiments, GBS growth was impeded by K12 independently of the megaplasmid. We also demonstrated that K12 adheres to and invades human vaginal epithelial cells at levels comparable to GBS. Inhibitory activity of K12 was examined in vivo using a mouse model of GBS vaginal colonization. Mice colonized with GBS were treated vaginally with K12. K12 administration significantly reduced GBS vaginal colonization in comparison to nontreated controls, and this effect was partially dependent on the K12 megaplasmid. Our results suggest that K12 may have potential as a preventative therapy to control GBS vaginal colonization and thereby prevent its transmission to the neonate during pregnancy.

    1993-01-01

    Constant denaturant gel electrophoresis (CDGE) was used to screen 179 breast carcinomas for mutations in the conserved regions of the TP53 gene (exons 5 through 8). Mutations were found in 35 of 163 primary tumours (21%) and in 5 of 16 metastases (31%) and resided predominantly in exon 7. The majority of the mutations were G:C-->A:T transitions. Immunohistochemistry demonstrated nuclear accumulation of p53 protein in 35 of 162 primary tumours (22%) and in four of 15 metastases (27%). TP53 mutation was strongly associated with nuclear accumulation of p53 protein. In total 42 of 163 primary tumours (26%) and 5 of 16 metastases (31%) were demonstrated to contain TP53 alterations (mutation and/or nuclear protein accumulation). TP53 alteration in primary tumour was significantly associated with the following parameters: positive node status, T status > 1, negative oestrogen receptor status, negative progesterone receptor status, presence of ERBB2 gene amplification, and invasive ductal histology. Furthermore, there were statistically significant associations, independent of other prognostic factors, between TP53 alterations in primary tumour and disease-free and overall survival.

  6. Chloride alterations in hospitalized patients: Prevalence and outcome significance

    Thongprayoon, Charat; Cheungpasitporn, Wisit; Cheng, Zhen

    2017-01-01

    Serum Cl (sCl) alterations in hospitalized patients have not been comprehensively studied in recent years. The aim of this study is to investigate the prevalence and outcome significance of (1) sCl alterations on hospital admission, and (2) sCl evolution within the first 48 hr of hospital admission. We conducted a retrospective study of all hospital admissions in the years 2011–2013 at Mayo Clinic Rochester, a 2000-bed tertiary medical center. Outcome measures included hospital mortality, length of hospital stay and discharge disposition. 76,719 unique admissions (≥18 years old) were studied. Based on hospital mortality, sCl in the range of 105–108 mmol/L was found to be optimal. sCl <100 (n = 13,611) and >108 (n = 11,395) mmol/L independently predicted a higher risk of hospital mortality, longer hospital stay and being discharged to a care facility. 13,089 patients (17.1%) had serum anion gap >12 mmol/L; their hospital mortality, when compared to 63,630 patients (82.9%) with anion gap ≤12 mmol/L, was worse. Notably, patients with elevated anion gap displayed a progressively worsening mortality with rising sCl. sCl elevation within 48 hr of admission was associated with a higher proportion of 0.9% saline administration and was an independent predictor for hospital mortality. Moreover, the magnitude of sCl rise was inversely correlated to the days of patient survival. In conclusion, serum Cl alterations on admission predict poor clinical outcomes. Post-admission sCl increase, due to Cl-rich fluid infusion, independently predicts hospital mortality. These results raise a critical question of whether iatrogenic cause of hyperchloremia should be avoided, a question to be addressed by future prospective studies. PMID:28328963

    1994-12-31

    In order to clarify the effect of mineral alteration on nuclide migration, we examined the processes, mechanisms, and kinetics of chlorite weathering, and the uranium concentrations in minerals and rocks at Koongarra, Australia. The observed concentrations of uranium in rocks were compared to those calculated. The sequence of chlorite weathering may be simply expressed as a chlorite {yields} vermiculite {yields} kaolinite conversion. These minerals occur as a function of depth, which corresponds well to uranium concentrations on the meter scale. Iron minerals, closely related to the uranium redistribution, are released during the weathering. The first-order kinetic model of the weathering process suggests that the weathering rate is not constant but time-dependent. The uranium concentrations are qualitatively proportional to the extent of the weathering, the weathered part having higher uranium concentration. Uranium mainly occurs with iron minerals, and sub micron sized saleeite, a uranyl phosphate, is one of the most probable uranyl phases associated with the iron minerals. The uranium fixation mechanisms are probably saleeite microcrystal coprecipitation and sorption to the iron minerals. Our model, which describes uranium concentrations in rocks as a function of time, shows that the transition zone (a vermiculite dominant area) plays an important role in the uranium migration. We have established that weathering of chlorite has affected the redistribution of uranium for more than one million years. The present study demonstrates the significance of mineral alteration when we estimate nuclide migration for geologic time.

  9. Scientists Involved in K-12 Education

    NASA Astrophysics Data System (ADS)

    2004-12-01

    The publication of countless reports documenting the dismal state of science education in the 1980s, and the Third International Mathematics and Science Study (TIMMS) report (1996) called for a wider involvement of the scientific community in K-12 education and outreach. Improving science education will not happen without the collaboration of educators and scientists working in a coordinated manner and it requires a long-term, continuous effort. To contribute effectively to K-12 education all scientists should refer to the National Science Education Standards, a set of policies that guide the development of curriculum and assessment. Ocean scientists can also specifically refer to the COSEE recommendations (www.cosee.org) that led to the creation of seven regional Centers for Ocean Sciences Education Excellence. Scientists can get involved in K-12 education in a multitude of ways. They should select projects that will accommodate time away from their research and teaching obligations, their talent, and their interest but also contribute to the education reform. A few examples of effective involvement are: 1) collaborating with colleagues in a school of education that can lead to better education of all students and future teachers, 2) acting as a resource for a national program or a local science fair, 3) serving on the advisory board of a program that develops educational material, 4) speaking out at professional meetings about the value of scientists' involvement in education, 5) speaking enthusiastically about the teaching profession. Improving science education in addition to research can seem a large, overwhelming task for scientists. As a result, focusing on projects that will fit the scientist's needs as well as benefit the science reform is of prime importance. It takes an enormous amount of work and financial and personnel resources to start a new program with measurable impact on students. So, finding the right opportunity is a priority, and stepping

  15. K-12 educational outcomes of immigrant youth.

    Crosnoe, Robert; Turley, Ruth N López

    2011-01-01

    The children from immigrant families in the United States make up a historically diverse population, and they are demonstrating just as much diversity in their experiences in the K-12 educational system. Robert Crosnoe and Ruth López Turley summarize these K-12 patterns, paying special attention to differences in academic functioning across segments of the immigrant population defined by generational status, race and ethnicity, and national origin. A good deal of evidence points to an immigrant advantage in multiple indicators of academic progress, meaning that many youths from immigrant families outperform their peers in school. This apparent advantage is often referred to as the immigrant paradox, in that it occurs despite higher-than-average rates of social and economic disadvantages in this population as a whole. The immigrant paradox, however, is more pronounced among the children of Asian and African immigrants than other groups, and it is stronger for boys than for girls. Furthermore, evidence for the paradox is far more consistent in secondary school than in elementary school. Indeed, school readiness appears to be one area of potential risk for children from immigrant families, especially those of Mexican origin. For many groups, including those from Latin America, any evidence of the immigrant paradox usually emerges after researchers control for family socioeconomic circumstances and youths' English language skills. For others, including those from Asian countries, it is at least partially explained by the tendency for more socioeconomically advantaged residents of those regions to leave their home country for the United States. Bilingualism and strong family ties help to explain immigrant advantages in schooling; school, community, and other contextual disadvantages may suppress these advantages or lead to immigrant risks. Crosnoe and Turley also discuss several policy efforts targeting young people from immigrant families, especially those of Latin

  16. Using Google Earth for K-12 Education

    NASA Astrophysics Data System (ADS)

    Kennedy, K.; Bailey, J. E.; Ornduff, T.

    2009-12-01

    Google Earth offers powerful medium for people to view the world. The ability to explore over mountains, through canyons, under oceans and even back in time to historical views of the landscape, makes it an ideal tool for teaching about the planet we live on. However, the true power of Google Earth is only fully unlocked when it is used as a background for dynamic geospatial content visualized through Keyhole Markup Language. Google Earth provides data layers both (e.g., roads) and dynamic (e.g. clouds) in nature. But KML allows for other, user-created content to be added. All of these data can form the basis for stories and lessons told with the backdrop of an interactive model of the Earth. Since 2006, educators from the University of Alaska Fairbanks (UAF) have worked in collaboration with Google to promote use, understanding and knowledge of Google Earth and KML in K-12 schools across the state of Alaska. Activities have included running workshops for teachers (of all technical abilities), visits to students in rural classrooms to provide hands-on tuition, and the development of lesson plans in combination with teachers in the community. The goal is to foster an understanding of how these tools work and to generate ideas of how they might enhance learning in the classroom. In this case, Alaska offers an excellent testing ground for methods that could be employed in other states or countries.

Grafton Local schools is located in a rural community and is using communications technology to bring to their students some of the same benefits students from suburban and urban areas receive. The Bug O Nay Ge Shig School is located on an Indian Reservation in Cass Lake, MN. The students at this school are using the computer to help them with geological studies. A grant has been issued to the friends of the Nashville Library. Nashville is a small township in Holmes County, Ohio. A community organization has been formed to turn their library into a state of the art Media Center. Their goal is to have a place where rural students can learn about different career options and how to go about pursuing those careers. Taylor High School in Cincinnati, Ohio was added to the schools involved in the Wind Tunnel Project. A mini grant has been awarded to Taylor High School for computer equipment. The computer equipment is utilized in the school's geometry class to computationally design objects which will be tested for their aerodynamic properties in the Barberton Wind Tunnel. The students who create the models can view the test in the wind tunnel via desk top conferencing. Two teachers received stipends for helping with the Regional Summer Computer Workshop. Both teachers were brought in to teach a session within the workshop. They were selected to teach the session based on their expertise in particular software applications.

  1. Addition of Cryoprotectant Significantly Alters the Epididymal Sperm Proteome

    PubMed Central

    2016-01-01

    Although cryopreservation has been developed and optimized over the past decades, it causes various stresses, including cold shock, osmotic stress, and ice crystal formation, thereby reducing fertility. During cryopreservation, addition of cryoprotective agent (CPA) is crucial for protecting spermatozoa from freezing damage. However, the intrinsic toxicity and osmotic stress induced by CPA cause damage to spermatozoa. To identify the effects of CPA addition during cryopreservation, we assessed the motility (%), motion kinematics, capacitation status, and viability of epididymal spermatozoa using computer-assisted sperm analysis and Hoechst 33258/chlortetracycline fluorescence staining. Moreover, the effects of CPA addition were also demonstrated at the proteome level using two-dimensional electrophoresis. Our results demonstrated that CPA addition significantly reduced sperm motility (%), curvilinear velocity, viability (%), and non-capacitated spermatozoa, whereas straightness and acrosome-reacted spermatozoa increased significantly (p < 0.05). Ten proteins were differentially expressed (two decreased and eight increased) (>3 fold, p < 0.05) after CPA, whereas NADH dehydrogenase flavoprotein 2, f-actin-capping protein subunit beta, superoxide dismutase 2, and outer dense fiber protein 2 were associated with several important signaling pathways (p < 0.05). The present study provides a mechanistic basis for specific cryostresses and potential markers of CPA-induced stress. Therefore, these might provide information about the development of safe biomaterials for cryopreservation and basic ground for sperm cryopreservation. PMID:27031703

  2. UPSeis - Visiting Seismographs for K-12 Schools

    NASA Astrophysics Data System (ADS)

    Wagner, S. R.; Len, S.; Pennington, W. D.

    2004-12-01

    Upper Peninsula Seismic Experiments in Schools (UPSeis) is an educational program developed to engage K-12 students in hands-on activities learning about earthquakes and Earth science. The system is intended to enhance teaching earth sciences to students, typically using teleseismic and regional earthquakes recorded directly in the classroom. This seismograph is computer-based and self-contained, requiring no hook-ups to the Internet or to advanced timing devices. It is easy to operate and relatively inexpensive to purchase. The UPSeis curriculum is designed so that a seismograph operates in a classroom for two or three months at a time, allowing the recording of at least 2 to 3 very large earthquakes somewhere in the world. The system comes with classroom activities, which are broken into several units, such as 'Seismic Waves', 'The UPSeis Technique' and 'Earthquake Hazards'. Within each unit, activities are rated for the appropriate grade level. All of the units have also been correlated to the Michigan Content Standards, and are easily adaptable to other state educational content standards as well. Our intention is to assist teachers and volunteers with bringing earth science into the classroom, by making it easier to obtain and operate seismographs. Ideally, a sponsor (University or Company) will pay for a system and any related costs. We further plan to train volunteers at conferences and meetings (such as AGU or SEG) in order to train them on a system and provide them with the knowledge required to assist teachers in the classroom. The volunteer would be available to come into the school and work with the teacher and students on some of the activities, particularly after they have recorded an earthquake. In addition, the volunteer would rotate their system between local area schools every 2 or 3 months. This allows teachers to use the system for a few months without the concern for maintenance of a permanent system. For schools interested in having a

    It has been increasingly evident that climatic extremes play crucial roles in the magnitudes and directions of carbon fluxes. However, significantly less is known about how these effects may change across multiple time and spatial scales. Here we used several databases collected from eddy-covariance (EC) towers and MODIS to understand these effects for: 1) long-term influences at an oak opening site (i.e. single site); 2) a cluster of EC fluxes from the Maumee watershed (i.e. different ecosystem types under the same climate); 3) several agricultural systems in the Midwest (i.e., same ecosystem among different climates); and 4) long term EVI, ET, GPP and LST (2000-2011) impacts across the Mongolia Plateau. We employed various wavelet analyses (transform, variance, coherency, and cross-wavelet) for the temporal data while an anomaly index was calculated for the spatial data on the plateau. As expected, the occurrences of extreme events and their influences varied greatly by year, but all produced significant and lasting effects on NEE, ER and, particularly on GEP. Three different ecosystems in the Maumee Watershed responded differently in magnitude/direction to the same climate anomaly (e.g. 2012 warmest March on record). Both the beginning time and magnitude of the NEE oscillation of the daily period at Oak Openings and the marshland were influenced by the unusual high March temperature, but the cropland ecosystem was less influenced because crops were not sown until the end of spring. Similarly, crops in different climates responded differently to the similar extremes. Across the broader spatiotemporal scales, we found that the forest biome more resistant to climatic extremes than the grassland and desert biomes on Mongolia Plateau. Frequency distributions of standardized anomalies of EVI during 2000-2010 showed that a number of the positively skewed years were more common in the desert biome compared to grasslands and forests.

  5. Designing Effective K-12 Educational Initiatives for Grant Proposals

    NASA Astrophysics Data System (ADS)

    Usselman, Marion

    2009-11-01

    The National Science Foundation requires that grantees make an effort to extend the reach of academic research to communities beyond the laboratory and address the work's possible ``Broader Impacts'' to society. NSF CAREER awards and many of the NSF Research Center grant solicitations are even more explicit, requiring that grantees craft educational initiatives that are based in best practices, bring the academic research to the broader community, and positively impact the pipeline of students pursuing science, technology, engineering and mathematics (STEM) education and careers. For new faculty, and even veteran faculty, these requirements for creative educational initiatives that significantly affect a community outside the confines of the laboratory can be very daunting. This presentation addresses how to design an effective educational plan that incorporates K-12 educational outreach, that will have a real impact on the target audience, and that can realistically be accomplished by a science faculty member.

  10. Test Of Astronomy STandards TOAST Survey of K-12 Teachers

    NASA Astrophysics Data System (ADS)

    Slater, Timothy F.; Slater, Stephanie; Stork, Debra J.

    2015-01-01

    Discipline-based education research in astronomy is focused on understanding the underlying mental mechanisms used by students when learning astronomy and teachers when teaching astronomy. Systematic surveys of K-12 teacher' knowledge in the domain of astronomy are conducted periodically in order to better focus and improve professional development. These surveys are most often done when doing contemporary needs assessments or when new assessment instruments are readily available. Designed by Stephanie J. Slater of the CAPER Center for Astronomy & Physics Education Research, the 29-item multiple-choice format Test Of Astronomy STandards - TOAST is a carefully constructed, criterion-referenced instrument constructed upon a solid list of clearly articulated and widely agreed upon learning objectives. The targeted learning concepts tightly align with the consensus learning goals stated by the American Astronomical Society - Chair's Conference on ASTRO 101, the American Association of the Advancement of Science's Project 2061 Benchmarks, and the National Research Council's 1996 National Science Education Standards. Without modification, the TOAST is also aligned with the significantly less ambitious 2013 Next Generation Science Standards created by Achieve, Inc., under the auspices of the National Research Council. This latest survey reveals that K-12 teachers still hold many of the same fundamental misconceptions uncovered by earlier surveys. This includes misconceptions about the size, scale, and structure of the cosmos as well as misconceptions about the nature of physical processes at work in astronomy. This suggests that professional development in astronomy is still needed and that modern curriculum materials are best served if they provide substantial support for implementation.

    NASA Astrophysics Data System (ADS)

    Bennett, K. F.

    2013-12-01

    Phenology is defined as periodic [or annual] life cycles of plants and animals driven by seasonal environmental changes. Climate change impinges a strong effect on phenology, potentially altering the structure and functioning of ecosystems. In the fall of 2011, the Ashburnham-Westminster Regional School District became the first of five schools to join Harvard University's Phenocam Network with the installation of a webcam to monitor phenology (or 'phenocam') at Overlook Middle School in Ashburnham, Massachusetts. Our school district is now part of a network of near-surface remote sensing phenocams that capture and send images of forest, shrub, and grassland vegetation cover at more than 130 diverse sites in North America. Our phenocam provides a digital image every half hour of the mixed forest canopy north from the school, enabling the detection of changes in canopy development, quantified as canopy 'greenness'. As a part of the Phenocam project, students at the K-12 level have expanded the scope of phenological monitoring protocol that is part of the Harvard Forest Schoolyard Ecology Program, Buds, Leaves, and Global Warming. In this protocol, students work with ecologists at Harvard Forest to monitor buds and leaves on schoolyard trees to determine the length of the growing season, giving them the opportunity to be a part of real and important research concerning the critical environmental issue of climate change. Students involved in the Buds, Leaves, and Global Warming study have the opportunity to compare their ground data on budburst, color change, and leaf drop to the phenocam images, as well as to similar forested sites in locations throughout the United States. Lessons have been developed for comparing student data to phenocam images, canopy greenness time series graphs extracted from the images, and satellite data. Lessons addressing map scale and the Urban Heat Island effect will also be available for teachers. This project will greatly enhance the

A mixed-method approach was used to examine student perspectives toward K--12 education careers, and the influence of the college experience on perspectives, at a public research university. Quantitative data come from a cross-sectional survey sample (N = 444) of upper-division natural science majors in the university. The survey focused on student background characteristics, undergraduate experiences, perceptions of the college environment, career interests, and satisfaction. Pursuit of K--12 education as a top current career choice was rare among the respondents (3.6%). However, about one-fourth of them indicated some interest in this career and overall interest increased slightly during the college experience. Based on student perceptions, K--12 education was substantially less emphasized within the natural sciences than other career fields. Regression analyses revealed that the most important predictors (aside from initial career interests) of interest in and attitude toward K--12 teaching were self-concept and personality measures. Several college experience measures were also predictors, including perceptions about faculty and peers in the natural sciences. The effect of college experiences differed for students initially more inclined toward K--12 teaching, who reported a net decrease in interest, versus those more disinclined, who reported a net gain in interest. Satisfaction with the college experience was similar for the two groups. Qualitative data come from follow-up interviews conducted with eight survey respondents who recalled a top choice of K--12 teaching upon entering college but had decided to pursue another career. These students perceived other career fields to offer better professional opportunities for

  12. Framing K-12 partnerships in order to make a difference.

    PubMed

    Hamos, James E

    2006-06-01

    The Health Professions Partnership Initiative (HPPI) furthered the establishment of partnerships between academic health centers and K-12 school systems. The present article contends that partnerships in efforts such as the HPPI exist in varying degrees of depth with deeper partnerships being those based in a concept of mutuality even as partners continue to maintain institutional identity. In the context of K-12 schools, the article reinforces the view that K-12 students, teachers, and administrators can benefit through partnership contexts, but also suggests that institutions of higher education-including academic health centers-should enter into partnerships because they benefit when they commit as stakeholders in the outcomes, not principally as altruistic good neighbors to the schools. Partnerships can continue to grow when multiple stakeholders accept mutual dependence as a norm, with goals, processes, and outcomes impacting each partner.

    This study demonstrates the effects of simulated microgravity on E. coli K 12 MG1655 grown on LB medium supplemented with glycerol. Global gene expression analysis indicated that the expressions of hundred genes were significantly altered in simulated microgravity conditions compared to that of normal gravity conditions. Under these conditions genes coding for adaptation to stress are up regulated (sufE and ssrA) and simultaneously genes coding for membrane transporters (ompC, exbB, actP, mgtA, cysW and nikB) and carbohydrate catabolic processes (ldcC, ptsA, rhaD and rhaS) are down regulated. The enhanced growth in simulated gravity conditions may be because of the adequate supply of energy/reducing equivalents and up regulation of genes involved in DNA replication (srmB) and repression of the genes encoding for nucleoside metabolism (dfp, pyrD and spoT). In addition, E. coli cultured in LB medium supplemented with glycerol (so as to protect the cells from freezing temperatures) do not exhibit multiple stress responses that are normally observed when cells are exposed to microgravity in LB medium without glycerol.

    Background. Walking and biking to work, active commuting (AC) is associated with many health benefits, though rates of AC remain low in the US. K-12 educators represent a significant portion of the workforce, and employee health and associated costs may have significant economic impact. Therefore, the purpose of this study was to examine the current rates of AC and factors associated with AC among K-12 educators. Methods. A volunteer sample of K-12 educators (n = 437) was recruited to participate in an online survey. Participants responded about AC patterns and social ecological influences on AC (individual, interpersonal, institutional, community, and environmental factors). t-tests and ANOVAs examined trends in AC, and Pearson correlations examined the relationship between AC and dependent variables. Multiple regression analysis determined the relative influence of individual, interpersonal, institutional, community, and environmental levels on AC. Results. Participants actively commuted 0.51 ± 1.93 times/week. There were several individual, interpersonal, institutional, community, and environmental factors significantly related to AC. The full model explained 60.8% of the variance in AC behavior. Conclusions. This study provides insight on the factors that determine K-12 educators mode of commute and provide some insight for employee wellness among this population. PMID:24089620

    The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

    A simulation-based technical feasibility study was completed to show the types of technologies required to achieve ZEB status with this building type. These technologies are prioritized across the building's subsystem such that design teams can readily integrate the ideas. Energy use intensity (EUI) targets were established for U.S. climate zones such that K-12 schools can be zero-ready or can procure solar panels or other renewable energy production sources to meet the zero energy building definition. Results showed that it is possible for K-12 schools to achieve zero energy when the EUI is between 20 and 26 kBtu/ft2/yr. Temperate climates required a smaller percentage of solar panel coverage than very hot or very cold climates. The paper provides a foundation for technically achieving zero energy schools with a vision of transforming the school construction market to mainstream zero energy buildings within typical construction budgets.

  17. Bridging the gap between community health and K-12 schools.

    Ahmed, Christine

    The topic of this article is program planning for K-12 school health programs collaborating with community agencies, businesses, colleges, and organizations. Community involvement was listed as one of the weakest areas of school health efforts in a national coordinated school health study [1]. This article presents the 5-year results demonstrating the outcomes of K-12 schools program planning aimed at community involvement in the coordinated school health model. Directors of the Departments of Education and Health in South Dakota initiated training for school personnel in the coordinated school health model through development of councils in the schools starting in 2000. The expectations of the councils were to design a program plan to support the health of students and staff in their school. The short-term results of a 5-year evaluation indicated the greatest area of gain was in community health involvement to improve student and staff health.

    We have created the first K-12 education activity using data provided by the National Virtual Observatory (NVO). The activity, ``Adopt an Object,'' was suggested by Heidi Kaiter, a middle school science teacher from Concord, MA. It is designed for middle school students, but could be adapted for high school and Astro 101 students as well. Each group of students selects a well-known sky object to ``adopt'' for detailed study. Students use the NVO's ``Data-Scope'' to look up multiwavelength images, observations, and catalog data for their object. The activity ends with a brief oral presentation and written report summarizing what each group has learned about their object. The activity includes a complete teacher's guide, with a lesson plan, additional resources, and correlations to national education standards. We are currently inviting K-12 teachers to field test the activity in their classes. We are also developing several other activities for K-12 and college teachers using NVO data. The activity discussed here is available online at http://www.voservices.net/nvoedu.

  20. Use of Cooperative K-12 Water Quality Data by Scientists

    2001-05-01

    Cooperative data collected by volunteers who are not paid professionals has been successfully used in weather observations, groundwater levels, and water quality. However, the notion of involving K-12 students directly in research, specifically concerning water quality data, has left many research scientists wondering "what about quality assurance and control (QA/QC)?" Global Learning and Observations to Benefit the Environment (GLOBE) is a worldwide network of K-12 students, teachers, and scientists working together to study and understand the global environment. Students and teachers from over 8,000 schools in more than 80 countries are working with research scientists to learn more about our planet. GLOBE students make environmental observations (hydrology, meteorology, soils, and other measurements) at or near their schools and report their data through the Internet (www.globe.gov). GLOBE and other parallel K-12 volunteer measurement programs have developed multi-year records of stream water quality at locations where career scientists do not or only infrequently sample. Since 1995, over 600 GLOBE schools throughout the U.S. have gathered and reported surface water quality data for alkalinity, electrical conductivity, dissolved oxygen, pH, and temperature. A comparative analysis of GLOBE and USGS water quality data, and the protocols used to make these measurements, was done to assess: i) how measurement protocols compare qualitatively, ii) how the variability in data compare, and iii) what spatial and/or temporal patterns are apparent in the data. When compared to equivalent USGS protocols, it becomes apparent that some of the GLOBE hydrology protocols can be improved. However there are limits to the quality of K-12 data imposed by the levels of scientific training of participants and sophistication of instrumentation. The higher spatial and statistical variability of GLOBE data compared to USGS data makes it unsuited for use as a stand-alone method for

  1. Females and STEM: Determining the K-12 Experiences that Influenced Women to Pursue STEM Fields

    NASA Astrophysics Data System (ADS)

    Petersen, Anne Marie

    In the United States, careers in the fields of Science, Technology, Engineering, and Mathematics (STEM) are increasing yet there are not enough trained personnel to meet this demand. In addition, of those that seek to pursue STEM fields in the United States, only 26% are female. In order to increase the number of women seeking STEM based bachelor's degrees, K-12 education must provide a foundation that prepares students for entry into these fields. The purpose of this phenomenological study was to determine the perceived K-12 experiences that influenced females to pursue a STEM field. Twelve college juniors or seniors seeking a degree in Biology, Mathematics, or Physics were interviewed concerning their K-12 experiences. These interviews were analyzed and six themes emerged. Teacher passion and classroom characteristics such as incorporating challenging activities played a significant role in the females' decisions to enter STEM fields. Extra-curricular activities such as volunteer and mentor opportunities and the females' need to benefit others also influenced females in their career choice. Both the formal (within the school) and informal (outside of the traditional classroom) pipeline opportunities that these students encountered helped develop a sense of self-efficacy in science and mathematics; this self-efficacy enabled them to persist in pursuing these career fields. Several participants cited barriers that they encountered in K-12 education, but these barriers were primarily internal as they struggled with overcoming self-imposed obstacles in learning and being competitive in the mathematics and science classrooms. The experiences from these female students can be used by K-12 educators to prepare and encourage current female students to enter STEM occupations.

  2. Infrared Astronomy Professional Development for K-12 Educators: WISE Telescope

    2010-01-01

    K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

    Educator Academy is a K-12 STEM curriculum developed by the STEM K-12 Outreach Committee of the American Institute of Aeronautics and Astronautics (AIAA). Consisting of three independent curriculum modules, K-12 students participate in inquiry-based engineering challenges to improve critical thinking skills and enhance problem solving skills. The Mars Rover Celebration Curriculum Module is designed for students in grades 3-8. Throughout this module, students learn about Mars and the solar system. Working with given design criteria, students work in teams to do basic research about Mars that will determine the operational objectives and structural features of their rover. Then, students participate in the design and construction of a model of a mock-up Mars Rover to carry out a specific science mission on the surface of Mars. At the end of this project, students have the opportunity to participate in a regional capstone event where students share their rover designs and what they have learned. The Electric Cargo Plan Curriculum Module is designed for students in grades 6-12. Throughout this module, students learn about aerodynamics and the four forces of flight. Working individually or in teams, students design and construct an electrically-powered model aircraft to fly a tethered flight of at least one lap without cargo, followed by a second tethered flight of one lap carrying as much cargo as possible. At the end of this project, students have the opportunity to participate in a regional capstone event where students share what they have learned and compete with their different cargo plane designs. The Space Weather Balloon Curriculum Module is designed for students in grades 9-12. Throughout this module, students learn and refine physics concepts as well as experimental research skills. Students participate in project-based learning that is experimental in nature. Students are engaged with the world around them as they collaborate to launch a high altitude

    We begin with the absurdity of ninth-grade biology to bewail the fate of high school science education as one component of a wholly inadequate K-12 education. Our proposal for a coherent physics-chemistry-biology core curriculum for all high school students leads naturally to seeking the connections between the sciences, the sciences and mathematics, and indeed to the social sciences and the humanities. Our goal is literacy--scientific and humanistic--as the sensible goal for a 21st century high school graduate.

    Patients with monoclonal gammopathy of undetermined significance (MGUS) are at increased fracture risk, and we have previously shown that MGUS patients have altered trabecular bone microarchitecture compared with controls. However, there are no data on whether the porosity of cortical bone, which may play a greater role in bone strength and the occurrence of fractures, is increased in MGUS. Thus, we studied cortical porosity and bone strength (apparent modulus) using high-resolution peripheral quantitative computed tomography imaging of the distal radius in 50 MGUS patients and 100 age-, gender-, and body mass index-matched controls. Compared with controls, MGUS patients had both significantly higher cortical porosity (+16.8%; P < .05) and lower apparent modulus (-8.9%; P < .05). Despite their larger radial bone size, MGUS patients have significantly increased cortical bone porosity and reduced bone strength relative to controls. This increased cortical porosity may explain the increased fracture risk seen in MGUS patients.

    Propacetamol, a water-soluble prodrug form of paracetamol, is hydrolyzed by esterase to generate paracetamol in the blood. Each gram of propacetamol is equal to 0.5 g of paracetamol. It has been reported to cause hypotension in critically ill patients with a fever. We aimed to investigate the hemodynamic effects of propacetamol for the control of fever in patients with diverse severities of illness who were managed in the emergency department (ED). We also aimed to identify clinical factors related to significant hemodynamic alterations in ED patients. This was a retrospective study of 1507 ED patients who received propacetamol. Significant hemodynamic alterations were defined as systolic blood pressure (SBP) <90 mmHg or diastolic blood pressure (DBP) <60 mmHg, or a drop in SBP >30 mmHg, which required treatments with a bolus of fluid or vasopressor administration. Postinfusion SBP and DBP were significantly lower than the preinfusion SBP and DBP. A clinically significant drop in BP occurred in 162 (10.7 %) patients, and interventions were necessary. Among the predictors assessed, congestive heart failure (OR 6.21, 95 % CI 2.67-14.45) and chills (OR 3.10, 95 % CI 2.04-4.70) were independent factors for a significant hemodynamic change. Administration of propacetamol can provoke a reduction in BP in ED patients. This reduction was clinically significant for 10 % of infusions. Clinicians should be aware of this potential deleterious effect, especially in patients with congestive heart failure or who experience chills prior to the administration of propacetamol.

    The Teachers on the Leading Edge (TOTLE) program has designed an innovative model for middle school teacher professional development related to Pacific NW plate margin hazards and EarthScope science. The program has been effective at improving teacher knowledge and confidence and has led to high rates of curricular implementation. The elements particularly key to success are: a) facilitation team with broad expertise in both geoscience and education; b) regional team format that encouraged learning community development; c) teachers' desire to focus on regional geologic hazards; d) significant use of animations and field trips to aid in "visualization" of processes; and e) extensive "kit" of teaching materials for easy classroom transfer. The 1-week workshops were held in summer 2008-2010 and 35 Pacific NW middle school teachers attended each year. Geoscientists from universities and research institutions conducted the field trips and content sessions. Master K-12 Earth science teachers designed or modified curricular materials and led the teaching implementation sessions. Each year, the teachers were divided into 5 regional teams led by geoscience educator team leaders (community college instructors or similar). Teachers were surveyed on teaching confidence and content knowledge before and after the workshops. Follow-up surveys addressed teaching confidence and curricular implementation and were conducted 0.7 years after (all cohorts), 1.7 years after (2009 cohort), and 2.7 years after (2008 cohort). Teacher confidence (4-point scale: 1="not at all confident"; 4="very confident") on workshop content topics continued to rise in each subsequent survey from 2.7 (pre) to 3.3 (post) to 3.5 (0.7 yr follow up) to 3.7 (2-3 yr follow up) suggesting the program impact is long-lived. In the post-workshop surveys, 100% of participants agreed or strongly agreed that the program would positively impact their teaching. Average teacher performance on content questions improved

    In the yeast Saccharomyces cerevisiae, complex sphingolipids have three types of polar head group and five types of ceramide; however, the physiological significance of the structural diversity is not fully understood. Here, we report that deletion of vacuolar H+-ATPase (V-ATPase) in yeast causes dramatic alteration of the complex sphingolipid composition, which includes decreases in hydroxylation at the C-4 position of long-chain bases and the C-2 position of fatty acids in the ceramide moiety, decreases in inositol phosphorylceramide (IPC) levels, and increases in mannosylinositol phosphorylceramide (MIPC) and mannosyldiinositol phosphorylceramide [M(IP)2C] levels. V-ATPase-deleted cells exhibited slow growth at pH 7.2, whereas the increase in MIPC levels was significantly enhanced when V-ATPase-deleted cells were incubated at pH 7.2. The protein expression levels of MIPC and M(IP)2C synthases were significantly increased in V-ATPase-deleted cells incubated at pH 7.2. Loss of MIPC synthesis or an increase in the hydroxylation level of the ceramide moiety of sphingolipids on overexpression of Scs7 and Sur2 sphingolipid hydroxylases enhanced the growth defect of V-ATPase-deleted cells at pH 7.2. On the contrary, the growth rate of V-ATPase-deleted cells was moderately increased on the deletion of SCS7 and SUR2. In addition, supersensitivities to Ca2+, Zn2+ and H2O2, which are typical phenotypes of V-ATPase-deleted cells, were enhanced by the loss of MIPC synthesis. These results indicate the possibility that alteration of the complex sphingolipid composition is an adaptation mechanism for a defect of V-ATPase.

    How does one bring night-time astronomical observations into the classroom? How does a teacher - during the school day - show students the craters on the Moon, the rings of Saturn, or the four Galilean moons of Jupiter? One of the greatest drawbacks to teaching Astronomy is the lack of real-time telescopic observations during the school day, and yet this is a very exciting time for astronomical discoveries. The solution is to access a telescope in a substantially different time zone where it is still night. This facility - the Aloha Telescope - on Maui has already been established by a partnership between Georgia Tech and the Air Force Research Lab. This robotic telescope's sole purpose is for K-12 education, as it is equipped with a video-camera and is operated remotely via high-speed internet connections. This facility and its outreach program allow east-coast teachers and, in turn, students to have local daytime access to - and direct control of - the telescope. When observing the Moon, teachers and students will move the telescope wherever they wish across the highly-magnified lunar surface (~ 5 arcminute FOV). This telescope will enable night-time astronomical observations to come alive as day-time activities and will be an important tool for STEM education and activities. The use of the Aloha Telescope requires minimal training and is free after registering for a date and time.Dr. Sowell has written specific telescopic exercises and surface feature tours appropriate for K-12 and college-level users. These exercises, and other aspects of the Aloha Telescope and program, are posted on the website at http://aloha.gatech.edu

    Many astronomers now have some involvement in K-12 education, either through their children, through large projects with an education or outreach office, or through an educational component to their own grants. Some may need to incorporate education components into future proposals. For those new to education, it can be difficult to decide how best to use their limited resources without "re-inventing the wheel." Some astronomers are comfortable taking a direct role in the classroom or working with teachers, others prefer developing web-based or printed materials, while still others wouldrather work with local schools of education to enhance the training of future teachers. Which of these roles is most useful? In this session, participants will learn what has worked well in the past, with special attention paid to ways in which astronomers' and physicists' training and instincts may fail them when working in education. Invited teachers will describe their classrooms and how astronomers can be most helpful to them. Sample (successful) activities will be demonstrated, and information given about the wide range of existing astronomy and space-science education programs around the country. A full menu of useful ways that astronomers can get involved will be presented, as well as the organizations and institutions which can help in devising a meaningful education program. Handouts will include a catalog of national astronomy education projects, a list of educational web sites, information about the NASA OSS education brokers and facilitators, examples of successful educational materials, and a listing of roles astronomers have played or could play to enhance K-12 education.

  13. Significant alterations in reported clinical practice associated with increased oversight of organ transplant center performance.

    2010-09-01

    In the past several years, emphasis on quality metrics in the field of organ transplantation has increased significantly, largely because of the new conditions of participation issued by the Centers for Medicare and Medicaid Services. These regulations directly associate patients' outcomes and measured performance of centers with the distribution of public funding to institutions. Moreover, insurers and marketing ventures have used publicly available outcomes data from transplant centers for business decision making and advertisement purposes. We gave a 10-question survey to attendees of the Transplant Management Forum at the 2009 meeting of the United Network for Organ Sharing to ascertain how centers have responded to the increased oversight of performance. Of 63 responses, 55% indicated a low or near low performance rating at their center in the past 3 years. Respondents from low-performing centers were significantly more likely to indicate increased selection criteria for candidates (81% vs 38%, P = .001) and donors (77% vs 31%, P < .001) as well as alterations in clinical protocols (84% vs 52%, P = .007). Among respondents indicating lost insurance contracts (31%), these differences were also highly significant. Based on respondents' perceptions, outcomes of performance evaluations are associated with significant changes in clinical practice at transplant centers. The transplant community and policy makers should practice vigilance that performance evaluations and regulatory oversight do not inadvertently lead to diminished access to care among viable candidates or decreased transplant volume.

    An increasing number of outbreaks of gastroenteritis recently caused by Escherichia coli O157:H7 have been linked to the consumption of leafy green vegetables. Although it is known that E. coli survives and grows in the phyllosphere of lettuce plants, the molecular mechanisms by which this bacterium associates with plants are largely unknown. The goal of this study was to identify E. coli genes relevant to its interaction, survival, or attachment to lettuce leaf surfaces, comparing E. coli K-12, a model system, and E. coli O157:H7, a pathogen associated with a large number of outbreaks. Using microarrays, we found that upon interaction with intact leaves, 10.1% and 8.7% of the 3,798 shared genes were differentially expressed in K-12 and O157:H7, respectively, whereas 3.1% changed transcript levels in both. The largest group of genes downregulated consisted of those involved in energy metabolism, including tnaA (33-fold change), encoding a tryptophanase that converts tryptophan into indole. Genes involved in biofilm modulation (bhsA and ybiM) and curli production (csgA and csgB) were significantly upregulated in E. coli K-12 and O157:H7. Both csgA and bhsA (ycfR) mutants were impaired in the long-term colonization of the leaf surface, but only csgA mutants had diminished ability in short-term attachment experiments. Our data suggested that the interaction of E. coli K-12 and O157:H7 with undamaged lettuce leaves likely is initiated via attachment to the leaf surface using curli fibers, a downward shift in their metabolism, and the suppression of biofilm formation.

    Successful implementation of marine conservation plans is largely inhibited by inadequate consideration of the broader social and economic context within which conservation operates. Marine waters and their biodiversity are shared by a host of stakeholders, such as commercial fishers, recreational users and offshore developers. Hence, to improve implementation success of conservation plans, we must incorporate other marine activities while explicitly examining trade-offs that may be required. In this study, we test how the inclusion of multiple marine activities can shape conservation plans. We used the entire Mediterranean territorial waters of Israel as a case study to compare four planning scenarios with increasing levels of complexity, where additional zones, threats and activities were added (e.g., commercial fisheries, hydrocarbon exploration interests, aquaculture, and shipping lanes). We applied the marine zoning decision support tool Marxan to each planning scenario and tested a) the ability of each scenario to reach biodiversity targets, b) the change in opportunity cost and c) the alteration of spatial conservation priorities. We found that by including increasing numbers of marine activities and zones in the planning process, greater compromises are required to reach conservation objectives. Complex plans with more activities incurred greater opportunity cost and did not reach biodiversity targets as easily as simplified plans with less marine activities. We discovered that including hydrocarbon data in the planning process significantly alters spatial priorities. For the territorial waters of Israel we found that in order to protect at least 10% of the range of 166 marine biodiversity features there would be a loss of ∼15% of annual commercial fishery revenue and ∼5% of prospective hydrocarbon revenue. This case study follows an illustrated framework for adopting a transparent systematic process to balance biodiversity goals and economic

    Mutations in BRCA1 and BRCA2 are responsible for a large proportion of breast-ovarian cancer families. Protein-truncating mutations have been effectively used in the clinical management of familial breast cancer due to their deleterious impact on protein function. However, the majority of missense variants identified throughout the genes continue to pose an obstacle for predictive informative testing due to low frequency and lack of information on how they affect BRCA1/2 function. Phosphorylation of BRCA1 and BRCA2 play an important role in their function as regulators of DNA repair, transcription and cell cycle in response to DNA damage but whether missense variants of uncertain significance (VUS) are able to disrupt this important process is not known. Here we employed a novel approach using NetworKIN which predicts in vivo kinase-substrate relationship, and evolutionary conservation algorithms SIFT, PolyPhen and Align-GVGD. We evaluated whether 191 BRCA1 and 43 BRCA2 VUS from the Breast Cancer Information Core (BIC) database can functionally alter the consensus phosphorylation motifs and abolish kinase recognition and binding to sites known to be phosphorylated in vivo. Our results show that 13.09% (25/191) BRCA1 and 13.95% (6/43) BRCA2 VUS altered the phosphorylation of BRCA1 and BRCA2. We highlight six BRCA1 (K309T, S632N, S1143F, Q1144H, Q1281P, S1542C) and three BRCA2 (S196I, T207A, P3292L) VUS as potentially clinically significant. These occurred rarely (n<2 in BIC), mutated evolutionarily conserved residues and abolished kinase binding to motifs established in the literature involved in DNA repair, cell cycle regulation, transcription or response to DNA damage. Additionally in vivo phosphorylation sites identified via through-put methods are also affected by VUS and are attractive targets for studying their biological and functional significance. We propose that rare VUS affecting phosphorylation may be a novel and important mechanism for which BRCA1 and

    Spaceflight factors, including microgravity and space radiation, have many detrimental short-term effects on human physiology, including muscle and bone degradation, and immune system dysfunction. The long-term progression of these physiological effects is still poorly understood, and a serious concern for long duration spaceflight missions. We hypothesized that some of the degenerative effects of spaceflight may be caused in part by an inability of stem cells to proliferate and differentiate normally resulting in an impairment of tissue regenerative processes. Furthermore, we hypothesized that long-term bone tissue degeneration in space may be mediated by activation of the p53 signaling network resulting in cell cycle arrest and/or apoptosis in osteoprogenitors. In our analyses we found that spaceflight caused significant bone loss in the weight-bearing bones of mice with a 6.3% reduction in bone volume and 11.9% decrease in bone thickness associated with increased osteoclastic activity. Along with this rapid bone loss we also observed alterations in the cell cycle characterized by an increase in the Cdkn1a/p21 cell cycle arrest molecule independent of Trp53. Overexpression of Cdkn1a/p21 was localized to osteoblasts lining the periosteal surface of the femur and chondrocytes in the head of the femur, suggesting an inhibition of proliferation in two key regenerative cell types of the femur in response to spaceflight. Additionally we found overexpression of several matrix degradation molecules including MMP-1a, 3 and 10, of which MMP-10 was localized to osteocytes within the shaft of the femur. This, in conjunction with 40 nm resolution synchrotron nano-Computed Tomography (nano-CT) observations of an increase in osteocyte lacunae cross-sectional area, perimeter and a decrease in circularity indicates a potential role for osteocytic osteolysis in the observed bone degeneration in spaceflight.

    Many important regulators of gene activity are natively disordered, but fully or partially order when they bind to their targets on DNA. Interestingly, the ensembles of disordered states for such free proteins are not structurally featureless, but can qualitatively differ from protein to protein. In particular, in random coil like states the chains are swollen, making relatively few contacts, while in molten globule like states a significant collapse occurs, with ensuing high density of intra-protein interactions. Furthermore, since many DNA binding proteins are positively charged polyelectrolytes, the electrostatic self-repulsion also influences the degree of collapse of the chain and its conformational preferences in the free state and upon binding to DNA. In our work, we have found that the nature of the natively disordered ensemble significantly affects the way the protein folds upon binding to DNA. In particular, we showed that posttranslational modifications of amino acid residues, such as lysine acetylation, can alter the degree of collapse and conformational preferences for a free protein, and also profoundly impact the binding affinity and pathways for the protein DNA association. These trends will be discussed in the context of DNA interacting with various histone tails and the p53 protein.

    2012-12-01

    As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons.

    The purpose of this study was to identify and describe strategies for creating and sustaining school-university partnerships for K--12 science education. This descriptive study focused on the science partnership experience of two research universities and their K--12 partner schools. The study utilized a theoretical approach of "appreciative inquiry" and examined the following questions: (1) What are the characteristics and processes of school-university science partnerships that enable them to develop and sustain the partnership? (2) What are the characteristics and process of school-university science partnerships that hinder and limit the partnership? The researcher made on-site visits to each university to collect survey and interview data from a total of forty-nine participants within six school-university science partnerships. This study was not designed to be generalizable to other partnerships. Participants' responses were analyzed according to three partnership themes generated from the literature in order to frame this study: governance, collaboration, and change. Three key school-university science partnership strategies emerged from this analysis: linking science partnerships with the academic mission of the university, with the student services mission of the university, and with school reform efforts. Core research results included: participants concurred science is more peripheral than reading, language arts, and math content areas in current K--6 curriculum; the majority of respondents reported faculties' participation in school-university partnerships is sustainable when tied to their academic and research interests and rewarded with credit toward tenure; most participants reported science partnerships are sustainable when they create an aggregate for change. This study concludes that: Current school reform efforts need to focus on teaching more science, especially in the K--6 curriculum. For science partnerships to be sustainable, faculty

    Space exploration remains a topic of immense interest and excitement for children and the general public. A diverse approach has been utilized at the Space Science and Engineering Center to initiate outreach and K-12 education activities. The hands-on experience gained through a working relationships with educators has been useful in understanding the challenges, usefulness and limitations of scientists' involvement in the education process. Our efforts have included school visits, development of lesson plans (KidSat), internet based activities (Planet Exploration Toolkit for Live from Mars, a Passport to Knowledge Project), World Wide Web, Public Lectures, summer teacher enhancement workshops, internships, and substitute teaching in science classes. The feedback and comments from teachers and students has demonstrated the usefulness and need for these efforts. The experience has also demonstrated that a committed effort in outreach is ultimately satisfying although immensely time consuming. Our outreach efforts have been partially supported by a NASA/IDEA grant, Wisconsin Space Grant Consortium, NOAA and more recently, the Evjue Foundation (Madison-Wisconsin).

    The lack of diversity in physics is a known problem, and yet efforts to change our demographics have only had minor effects during the last decade. I will explain some of the hidden barriers that dissuade underrepresented minorities in becoming physicists using a framework borrowed from sociology, Maslow's hierarchy of needs. I will draw from current research at the undergraduate to faculty levels over a variety of STEM fields that are also addressing a lack of diversity. I will also provide analysis from the Joint Institute for Nuclear Astrophysics Center for the Evolution of Elements (JINA-CEE) outreach programs to understand the likelihood of current K-12 students in becoming physicists. Specifically, I will present results from the pre-surveys from our Art 2 Science Camps (ages 8-14) about their attitudes towards science as well as results from analysis of teacher recommendations for our high school summer program. I will conclude with a positive outlook describing the pipeline created by JINA-CEE to retain students from middle school through college. This work was supported in part by the National Science Foundation under Grant No. PHY-1430152 (JINA Center for the Evolution of the Elements).

    Since the mid 1990s the Electronic Visualization Laboratory at the University of Illinois at Chicago has been investigating how advanced visualization technology such as CAVEs, ImmersaDesks, PCs, and plasma panels can be used effectively in K-12 education. The creation of the GeoWall has given us more flexibility in deploying these technologies, and conducting these investigations outside the laboratory. Over the two years we have been using GeoWalls in a variety of educational settings around the Chicago area. Since the Fall of 2002, the SciTech Museum in Aurora, IL has used a GeoWall to show a variety of educational content. In February 2002 the Museum of Science and Industry in Chicago, IL set up a GeoWall to show 'Virtual Harlem' which allowed museum patrons to walk the streets of Harlem NY in the 1930s to learn about the place and the people. Since 1999 we have been working with Abraham Lincoln Elementary School in Oak Park, IL using a variety of display devices to teach the scientific method and investigate the use of multiple perspectives in learning. We began using a GeoWall there in the spring of 2002 and in the spring of 2003 we expanded our work in Oak Park to include Gwendolyn Brooks Middle School.

    1997-01-01

    Escherichia coli K-12 can utilize D-allose, an all-cis hexose, as a sole carbon source. The operon responsible for D-allose metabolism was localized at 92.8 min of the E. coli linkage map. It consists of six genes, alsRBACEK, which are inducible by D-allose and are under the control of the repressor gene alsR. This operon is also subject to catabolite repression. Three genes, alsB, alsA, and alsC, appear to be necessary for transport of D-allose. D-Allose-binding protein, encoded by alsB, is a periplasmic protein that has an affinity for D-allose, with a Kd of 0.33 microM. As was found for other binding-protein-mediated ABC transporters, the allose transport system includes an ATP-binding component (AlsA) and a transmembrane protein (AlsC). It was found that AlsE (a putative D-allulose-6-phosphate 3-epimerase), but not AlsK (a putative D-allose kinase), is necessary for allose metabolism. During this study, we observed that the D-allose transporter is partially responsible for the low-affinity transport of D-ribose and that strain W3110, an E. coli prototroph, has a defect in the transport of D-allose mediated by the allose permease.

    The Earth System Science Education Alliance (ESSEA) is a partnership between the Institute for Global Environmental Strategies (IGES) and the Center for Educational Technologies (CET) at Wheeling Jesuit University, through funding from NASA's Earth Science Enterprise. ESSEA is supporting universities, colleges, and science education organizations in offering K-12 Earth system science online graduate courses that have been developed within the CET at Wheeling Jesuit University for NASA's Earth Science Enterprise. The Earth system science courses use an inquiry-based instructional design model, are delivered over the Internet, and feature student-centered, knowledge-building virtual communities. They have been successfully implemented for both in-service and pre-service teacher education. An annual announcement by ESSEA solicits proposals from US teams interested in offering the courses. Currently 12 institutions from across the US are offering the courses to teachers, with plans to select 7 new organizations in early 2001. This presentation will focus on the content and structure of the courses, which can be freely downloaded and used by any organization, as well as lessons learned about online instruction.

    To better understand the molecular basis underlying aphid immune tolerance to beneficial bacteria and immune defense to pathogenic bacteria, we characterized how the pea aphid Acyrthosiphon pisum responds to Escherichia coli K-12 infections. E. coli bacteria, usually cleared in the hemolymph of other insect species, were capable of growing exponentially and killing aphids within a few days. Red fluorescence protein expressing E. coli K-12 laboratory strain multiplied in the aphid hemolymph as well as in the digestive tract, resulting in death of infected aphids. Selected gene deletion mutants of the E. coli K-12 predicted to have reduced virulence during systemic infections showed no difference in either replication or killing rate when compared to the wild type E. coli strain. Of note, however, the XL1-Blue E. coli K-12 strain exhibited a significant lag phase before multiplying and killing aphids. This bacterial strain has recently been shown to be more sensitive to oxidative stress than other E. coli K-12 strains, revealing a potential role for reactive oxygen species-mediated defenses in the otherwise reduced aphid immune system.

    Excess calorie intake is a growing global problem. This study investigated effect of complexing partially gelatinized starch with condensed tannins on in vitro starch digestibility. Extracts from tannin and non-tannin sorghum, and cellulose control, were reacted with normal and waxy maize starch in 30% (30E) and 50% ethanol (50E) solutions at 70°C/20min. More tannins complexed with the 30E than 50E starches (mean 6.2 vs 3.5mg/g, respectively). In the 30E treatments, tannins significantly increased crystallinity, pasting temperature, peak viscosity, and slow digesting starch (from 100 to 274mg/g) in normal, but not waxy starch, suggesting intragranular cross-linking with amylose. Tannins doubled resistant starch (RS) to approx. 300mg/g in both starches. In 50E treatments, tannins made both maize starches behave like raw potato starch (>90% RS), suggesting granule surface interactions dominated. Non-tannin treatments generally behaved similar to cellulose. Condensed tannins could be used to favorably alter starch digestion profile.

    Oral candidiasis is often accompanied by severe inflammation, resulting in a decline in the quality of life of immunosuppressed individuals and elderly people. To develop a new oral therapeutic option for candidiasis, a nonpathogenic commensal oral probiotic microorganism, Streptococcus salivarius K12, was evaluated for its ability to modulate Candida albicans growth in vitro, and its therapeutic activity in an experimental oral candidiasis model was tested. In vitro inhibition of mycelial growth of C. albicans was determined by plate assay and fluorescence microscopy. Addition of S. salivarius K12 to modified RPMI 1640 culture medium inhibited the adherence of C. albicans to the plastic petri dish in a dose-dependent manner. Preculture of S. salivarius K12 potentiated its inhibitory activity for adherence of C. albicans. Interestingly, S. salivarius K12 was not directly fungicidal but appeared to inhibit Candida adhesion to the substratum by preferentially binding to hyphae rather than yeast. To determine the potentially anti-infective attributes of S. salivarius K12 in oral candidiasis, the probiotic was administered to mice with orally induced candidiasis. Oral treatment with S. salivarius K12 significantly protected the mice from severe candidiasis. These findings suggest that S. salivarius K12 may inhibit the process of invasion of C. albicans into mucous surfaces or its adhesion to denture acrylic resins by mechanisms not associated with the antimicrobial activity of the bacteriocin. S. salivarius K12 may be useful as a probiotic as a protective tool for oral care, especially with regard to candidiasis.

    Bachmann, B J

    1990-01-01

    The linkage map of Escherichia coli K-12 depicts the arrangement of genes on the circular chromosome of this organism. The basic units of the map are minutes, determined by the time-of-entry of markers from Hfr into F- strains in interrupted-conjugation experiments. The time-of-entry distances have been refined over the years by determination of the frequency of cotransduction of loci in transduction experiments utilizing bacteriophage P1, which transduces segments of DNA approximately 2 min in length. In recent years, the relative positions of many genes have been determined even more precisely by physical techniques, including the mapping of restriction fragments and the sequencing of many small regions of the chromosome. On the whole, the agreement between results obtained by genetic and physical methods has been remarkably good considering the different levels of accuracy to be expected of the methods used. There are now few regions of the map whose length is still in some doubt. In some regions, genetic experiments utilizing different mutant strains give different map distances. In other regions, the genetic markers available have not been close enough to give accurate cotransduction data. The chromosome is now known to contain several inserted elements apparently derived from lambdoid phages and other sources. The nature of the region in which the termination of replication of the chromosome occurs is now known to be much more complex than the picture given in the previous map. The present map is based upon the published literature through June of 1988. There are now 1,403 loci placed on the linkage group, which may represent between one-third and one-half of the genes in this organism. PMID:2194094

    PubMed Central

    Siegel, Eli C.

    1973-01-01

    An ultraviolet (UV)-sensitive mutator gene, mutU, was identified in Escherichia coli K-12. The mutation mutU4 is very close to uvrD, between metE and ilv, on the E. coli chromosome. It was recessive as a mutator and as a UV-sensitive mutation. The frequency of reversion of trpA46 on an F episome was increased by mutU4 on the chromosome. The mutator gene did not increase mutation frequencies in virulent phages or in lytically grown phage λ. The mutU4 mutation predominantly induced transitional base changes. Mutator strains were normal for recombination and host-cell reactivation of UV-irradiated phage T1. They were normally resistant to methyl methanesulfonate and were slightly more sensitive to gamma irradiation than Mut+ strains. UV irradiation induced mutations in a mutU4 strain, and phage λ was UV-inducible. Double mutants containing mutU4 and recA, B, or C were extremely sensitive to UV irradiation; a mutU4 uvrA6 double mutant was only slightly more sensitive than a uvrA6 strain. The mutU4 uvrA6 and mutU4 recA, B, or C double mutants had mutation rates similar to that of a mutU4 strain. Two UV-sensitive mutators, mut-9 and mut-10, isolated by Liberfarb and Bryson in E. coli B/UV, were found to be co-transducible with ilv in the same general region as mutU4. PMID:4345920

    The complexities and uncertainties associated with the science of global climate change is a barrier to the implementation of global change into K-12 classrooms. This issue is part of a larger conundrum where by teachers who are not well-versed in the content of an emerging science field are less likely to incorporate that topic into their curriculum. As such, it is not surprising that the K-12 community has been slow to embrace global climate change as a curriculum element, given that science underlying global climate change is interdisciplinary and replete with new discoveries, complex models, and competing theories. Faculty members associated with the Big Sky Institute have experimented with ways to promote collaboration between researchers and educators to enhance scientific literacy. In 2004, with funding from the US Environmental Protection Agency and private foundations, we implemented a five-day, field based professional development workshop for middle and high school teachers that focused on the research underlying EPA's Climate Change, Wildlife and Wildlands curriculum. A primary objective of the overall project is to promote one-on-one engagement of teachers with researchers whose work forms the basis of the content of the curriculum. Further, we seek to assess the degree to which increased content knowledge leads to incorporation of global climate change content into classrooms and curricula. During the workshop, we focused on two broad research findings, namely: 1) Global climate change is systemically pervasive such that even wildlands (i.e., unmanaged, pristine parks and reserves) are or potentially will be altered by global climate change. 2) At the same time, natural climate variability may enhance or mask human-induced climate impacts on wildlands and wildlife. In addition, we emphasized two broadly framed "ways of thinking" about global climate change, namely: 1) Wildlands can be used to detect and measure the impacts of human-induced climate

    Monoclonal gammopathy of undetermined significance (MGUS) is a benign condition with an approximate 1% annual risk of symptomatic plasma cell disorder development, mostly to multiple myeloma (MM). We performed genomewide screening of copy-number alterations (CNAs) in 90 MGUS and 33 MM patients using high-density DNA microarrays. We identified CNAs in a smaller proportion of MGUS (65.6%) than in MM (100.0%, P = 1.31 × 10(-5) ) and showed median number of CNAs is lower in MGUS (3, range 0-22) than in MM (13, range 4-38, P = 1.82 × 10(-10) ). In the MGUS cohort, the most frequent losses were located at 1p (5.6%), 6q (6.7%), 13q (30.0%), 14q (14.4%), 16q (8.9%), 21q (5.6%), and gains at 1q (23.3%), 2p (6.7%), 6p (13.3%), and Xq (7.8%). Hyperdiploidy was detected in 38.9% of MGUS cases, and the most frequent whole chromosome gains were 3 (25.6%), 5 (23.3%), 9 (37.8%), 15 (23.3%), and 19 (32.2%). We also identified CNAs such as 1p, 6q, 8p, 12p, 13q, 16q losses, 1q gain and hypodiploidy, which are potentially associated with an adverse prognosis in MGUS. In summary, we showed that MGUS is similar to MM in that it is a genetically heterogeneous disorder, but overall cytogenetic instability is lower than in MM, which confirms that genetic abnormalities play important role in monoclonal gammopathies.

  19. Clinical Significance of Epigenetic Alterations in Human Hepatocellular Carcinoma and Its Association with Genetic Mutations.

    PubMed

    Nishida, Naoshi; Kudo, Masatoshi

    Accumulation of genetic and epigenetic alterations is a hallmark of cancer genomes, including those in hepatocellular carcinoma (HCC). Particularly, in human HCC, epigenetic changes are more frequently observed than genetic changes in a variety of cancer-related genes, suggesting a potential role for epigenetic alterations during hepatocarcinogenesis. Several environmental factors, such as inflammation, obesity, and steatosis, are reported to affect the epigenetic status in hepatocytes, which could play a role in HCC development. In addition, genetic mutations in histone modulators and chromatin regulators would be critical for the acceleration of epigenetic alteration. It is also possible that major genetic mutations of HCC, such as TP53 and CNTTB1 mutations, are associated with the disturbance of epigenetic integrity. For example, specific TP53 mutations frequently induced by aflatoxin B1 exposure might affect histone modifiers and nucleosome remodelers. Generally, epigenetic alteration is reversible, because of which dysregulation of transcription takes place, without affecting protein structure. Therefore, differentiation therapy is one of the potential approaches for HCC with advanced epigenetic alterations. On the other hand, a tumor carrying an accumulation of genetic mutations would result in many abnormal proteins that could be recognized as non-self and could be targets for immune reactions; thus, immune-checkpoint blockers should be effective for HCCs with genetic hypermutation. Although the emergence of genetic and epigenetic alterations could be linked to each other and there could be some crossover or convergence between these cancer pathways, characterization of the mutation spectrum of genetic and epigenetic alterations could influence future HCC treatment.

    2015-12-01

    Cool science is an art contest where K12 students create placards (7" x 22") to educate the public about climate change. Students are prompted to create their artwork in response to questions such as: What is the evidence for climate change? How does climate change impact your local community? What can you do to reduce the impacts of climate change? In each of three years, 500-600 student entrees have been submitted from more than 12 school districts across Massachusetts. A panel of judges including scientists, artists, rapid transit representatives, and educators chooses elementary, middle, and high school winners. Winners (6), runners-up (6), and honorable mentions (12) and their families and teachers are invited to an annual Cool Science Award Ceremony to be recognized and view winning artwork. All winning artwork is posted on the Cool Science website. The winning artwork (2 per grade band) is converted into placards (11" x 28") and posters (2.5' x 12') that are placed on the inside (placards) and outside (posters) of buses. Posters are displayed for one month. So far, Cool Science was implemented in Lowell, MA where over 5000 public viewers see the posters daily on the sides of Lowell Rapid Transit Authority (LRTA) buses, making approximately 1,000,000 impressions per year. Cool Science acts to increase climate literacy in children as well as the public, and as such promotes intergenerational learning. Using art in conjunction with science learning about climate change appears to be effective at engaging not just traditionally high achieving science students, but also those interested in the creative arts. Hearing winners' stories about how they created their artwork and what this contest meant to them supports the idea that Cool Science attracts a wide diversity of students. Parents discuss climate change with their children. Multiple press releases announcing the winners further promotes the awareness of climate change throughout school districts and their

    The University of New England’s Center for Excellence in the Neurosciences has developed a successful and growing K-12 outreach program that incorporates undergraduate and graduate/professional students. The program has several goals, including raising awareness about fundamental issues in neuroscience, supplementing science education in area schools and enhancing undergraduate and graduate/professional students’ academic knowledge and skill set. The outreach curriculum is centered on core neuroscience themes including: Brain Safety, Neuroanatomy, Drugs of Abuse and Addiction, Neurological and Psychiatric Disorders, and Cognition and Brain Function. For each theme, lesson plans were developed based upon interactive, small-group activities. Additionally, we’ve organized our themes in a “Grow-up, Grow-out” approach. Grow-up refers to returning to a common theme, increasing in complexity as we revisit students from early elementary through high school. Grow-out refers to integrating other scientific fields into our lessons, such as the chemistry of addiction, the physics of brain injury and neuronal imaging. One of the more successful components of our program is our innovative team-based model of curriculum design. By creating a team of undergraduate, graduate/professional students and faculty, we create a unique multi-level mentoring opportunity that appears to be successful in enhancing undergraduate students’ skills and knowledge. Preliminary assessments suggest that undergraduates believe they are enhancing their content knowledge and professional skills through our program. Additionally, we’re having a significant, short-term impact on K-12 interest in science. Overall, our program appears to be enhancing the academic experience of our undergraduates and exciting K-12 students about the brain and science in general. PMID:25565921

  4. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

    This study evaluated the efficacy of a supercritical carbon dioxide (SCCO(2)) system with a gas-liquid porous metal contactor for eliminating Escherichia coli K12 in apple cider. Pasteurized, preservative-free apple cider was inoculated with E. coli K12 and processed using the SCCO(2) system at CO(2) concentrations of 0-10% (wt.%, g CO(2)/100g product), outlet temperatures of 34, 38, and 42 degrees C, a system pressure of 7.6 MPa, and a flow rate of 1L/min. Increased CO(2) concentrations and temperatures significantly (P<0.05) enhanced the bactericidal effect, resulting in a maximum reduction of 7.31 log CFU/mL at 8% CO(2) and 42 degrees C. A response surface model indicated that minimum CO(2) concentrations of 9.9% at 34 degrees C, 7.4% at 38 degrees C, and 5.4% at 42 degrees C are needed to achieve a 5-log reduction of E. coli K12 in apple cider. SEM observations showed morphological changes in the cell envelope after SCCO(2) processing. At a processing condition of 8% and 38 degrees C, the reduction of E. coli was 6.03 log and the sublethal injury of the survivors was 84%. The regrowth or survival of E. coli in SCCO(2) processed apple cider was not observed during storage for 28 days at 4, 8, and 20 degrees C. Thus this study showed the potential of SCCO(2) processing with a gas-liquid porous metal contactor for the nonthermal pasteurization of apple cider.

  7. Positive clinical outcomes derived from using Streptococcus salivarius K12 to prevent streptococcal pharyngotonsillitis in children: a pilot investigation

    2016-01-01

    Background Streptococcus salivarius K12 (BLIS K12®) is a probiotic strain producing the bacteriocins salivaricin A2 and salivaricin B, both of which strongly antagonize the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. It successfully colonizes and exhibits persistence in the oral cavity and is endowed with an excellent safety profile. Previous observations of a small group of children indicated that the use of BLIS K12 could also reduce the occurrence of viral pharyngitis. The present study focused on a further evaluation of the role of BLIS K12 in the control of pediatric streptococcal disease and moreover whether its use could also help provide protection against various nonstreptococcal infections. Methods In total, 48 children with a recent history of recurrent pharyngeal streptococcal disease were enrolled in the treated group. The control group comprised 76 children known to have had a very low recent occurrence of oral streptococcal disease. The treated children were given BLIS K12 daily for 90 days. The number of episodes of streptococcal pharyngotonsillitis, tracheitis, viral pharyngitis, rhinitis, flu, laryngitis, acute otitis media, enteritis, and stomatitis was recorded during probiotic treatment and for a follow-up period of 9 months, and this was compared with the episodes of the control group over the corresponding period. Results Compared with the pretreatment time period, 2013, a 90% reduction of streptococcal pharyngeal disease was observed in 2014; compared with untreated children, a statistically significant reduction of all of the other disease conditions assessed, other than stomatitis, was detected in the probiotic-treated children. Conclusion In agreement with previous findings, in the present study, it was found that the daily use of BLIS K12 has been associated with a concurrent and persisting reduction in the occurrence of pharyngeal, recurrent, streptococcal disease.

    The Next Generation Science Standards (NGSS) provide an historic opportunity to significantly improve Earth and space science (ESS) education nationally at the K-12 level. The increased emphasis on ESS related topics in the NGSS relative to previous standards provides a real opportunity for ensuring all K-12 students in adopting states learn about the ESS - allowing us to reach many more students than are currently are exposed to our discipline. The new standards are also exciting in that they explicitly couple science and engineering practice, cross-cutting concepts, and disciplinary core ideas in such a way that student must actively demonstrate their understanding through actions rather than through mere regurgitation of memorized responses. Achieving mastery of NGSS Performance Expectations will require practice with higher-order learning skills - with students engaging in the practices of scientists and engineers. Preparing students for this mastery will be a challenging task for teachers, since in many states professional development support is limited at best for the current curriculum - let alone the curricula that will be developed to address the NGSS. As adoption of the NGSS expands across the country, states will be at various levels of implementation of the new standards over the next several years - and there is real concern that teachers must have sufficient professional development to be able to be successful in preparing their students - particularly in view of likely coupled assessments and teacher evaluations. NESTA strongly supports implementation of the NGSS, and the rigorous and compelling ESS education it will engender, when coupled with a strong emphasis nationwide on teacher professional development. For the past two years, the National Earth Science Teachers Association (NESTA) has continued our leadership in K-12 ESS education through workshops, web seminars, events and publications that emphasize implementation of the NGSS in ESS

  9. Frustration, anger, and the significance of alter-ego transferences in group psychotherapy.

    PubMed

    Stone, W N

    1995-07-01

    When working with narcissistically vulnerable and angry patients in group psychotherapy one must take into account the entire treatment context. Interaction takes place among the identified patient, the other members, the therapist, and the image of the group as a whole. In members' counter-reactions to the difficult person, group-destructive forces frequently are stimulated. The offending individual may flee, or the group may reach an impasse in which little growth occurs. In this communication, I have focused on alter-ego relationships and transferences as a way of understanding aspects of group formation and destruction. Angry patients may have intense wishes to be like others and to feel part of the human condition. They suffer from feeling alone. Disruption of an alter-ego relationship may result in rage. A self-psychological perspective in concert with knowledge of group dynamics enables the clinician to formulate ways of intervening in problematic group interactions. The therapist's capacity to attend to the vulnerabilities of the self of all persons involved in the group is often severely tested, particularly under circumstances of emotional contagion. Elucidation of twinship and alter-ego transferences may help stabilize difficult patients and enable them to restart their psychological growth.

    Selected K--12 public school science educators in 14 eastern North Carolina counties were surveyed to examine their perceptions of their undergraduate preparation programs with regard to instructing students with learning disabilities in the regular classroom. A quantitative study, this research examined science educator preparedness in instructing students with learning disabilities by evaluating educator perception in regard to mainstrearned and inclusive educational settings. Specifically, two null hypotheses were tested. Null hypothesis I stated a significant difference does not exist between selected North Carolina K--12 science educators' perceptions of their undergraduate teacher education preparation programs and their perceptions of their abilities to instruct students needing accommodations on behalf of their learning disabilities in mainstrearned or inclusive settings. Participants' responses to perception as well as value statements regarding opinions, adaptations, and undergraduate training with respect to mainstreaming and inclusion were evaluated through t-test analyses of 22 Likert-scale items. Null hypothesis 1 was not accepted because a statistically significant difference did exist between the educators' perceptions of their undergraduate training and their perceived abilities to instruct students with learning disabilities in mainstreamed or inclusive settings. Null hypothesis 2 stated a significant difference does not exist between selected North Carolina K--12 science educators' attained educational level; grade level currently taught, supervised or chaired; and years of experience in teaching science, supervising science education, and/or chairing science departments in selected North Carolina public schools and their opinions of their undergraduate teacher education program with regard to instructing students with learning disabilities in mainstreamed or inclusive educational settings.

  12. The Significance of Acid Alteration in the Los Humeros High-Temperature Geothermal Field, Puebla, Mexico.

    NASA Astrophysics Data System (ADS)

    Elders, W. A.; Izquierdo, G.

    2014-12-01

    The Los Humeros geothermal field is a high-enthalpy hydrothermal system with more than 40 drilled deep wells, mostly producing high steam fractions at > 300oC. However, although it has a large resource potential, low permeability and corrosive acid fluids have hampered development so that it currently has an installed electrical generating capacity of only 40 MWe. The widespread production of low pH fluids from the reservoir is inconsistent with the marked absence in the reservoir rocks of hydrothermal minerals typical of acid alteration. Instead the hydrothermal alteration observed is typical of that due to neutral to alkaline pH waters reacting with the volcanic rocks of the production zones. Thus it appears that since the reservoir has recently suffered a marked drop in fluid pressure and is in process of transitioning from being water-dominated to being vapor-dominated. However sparse examples of acid leaching are observed locally at depths of about 2 km in the form of bleached, intensely silicified zones, in low permeability and very hot (>350oC) parts of reservoir. Although these leached rocks retain their primary volcanic and pyroclastic textures, they are altered almost entirely to microcrystalline quartz, with some relict pseudomorphs of plagioclase phenocrysts and traces of earlier-formed hydrothermal chlorite and pyrite. These acid-altered zones are usually only some tens of meters thick and deeper rocks lack such silicification. The acid fluids responsible for their formation could either be magmatic volatiles, or could be formed during production (e.g. reaction of water and salts forming hydrogen chloride by hydrolysis at high temperatures). The very high boron content of the fluids produced by the Los Humeros wells suggests that their ultimate source is most likely magmatic gases. However, these acid gases did not react widely with the rocks. We suggest that the silicified zones are forming locally where colder descending waters are encountering

    Obesity and sarcopenia have been associated with mineral metabolism derangement and low bone mineral density (BMD). We investigated whether imbalance of serum factors in obese or obese sarcopenic patients could affect bone cell activity in vitro. To evaluate and characterize potential cellular and molecular changes of human osteoblasts, cells were exposed to sera of four groups of patients: (1) affected by obesity with normal BMD (O), (2) affected by obesity with low BMD (OO), (3) affected by obesity and sarcopenia (OS), and (4) affected by obesity, sarcopenia, and low BMD (OOS) as compared to subjects with normal body weight and normal BMD (CTL). Patients were previously investigated and characterized for body composition, biochemical and bone turnover markers. Then, sera of different groups of patients were used to incubate human osteoblasts and evaluate potential alterations in cell homeostasis. Exposure to OO, OS, and OOS sera significantly reduced alkaline phosphatase, osteopontin, and BMP4 expression compared to cells exposed to O and CTL, indicating a detrimental effect on osteoblast differentiation. Interestingly, sera of all groups of patients induced intracellular alteration in Wnt/β-catenin molecular pathway, as demonstrated by the significant alteration of specific target genes expression and by altered β-catenin cellular compartmentalization and GSK3β phosphorylation. In conclusion our results show for the first time that sera of obese subjects with low bone mineral density and sarcopenia significantly alter osteoblasts homeostasis in vitro, indicating potential detrimental effects of trunk fat on bone formation and skeletal homeostasis.

    Berry shriveling is an often reported occurrence in the Shiraz (Vitis vinifera L.) cultivar. This study investigated the effect of berry shriveling occurring in a high yielding (18.6 ± 1.6 kg/vine) Shiraz vineyard in relation to a temporal investigation of grape and wine composition using three harvest dates. Berry shriveling resulted in delayed total soluble solids and amino acid accumulation into the berry, however differences between treatments diminished or became smaller by the third harvest date. Similarly, ethyl esters of fatty acids and higher alcohol acetates were lower in wines from shriveled berries from the first two harvests; anthocyanins were reduced in wines from shriveled berries at all harvest dates, whereas terpenes were unaltered. Wines made from shriveled berries had higher γ-nonalactone and β-damascenone concentrations. This study provides novel information on the chemical alterations of grapes and wines made from grapes affected by shriveling.

    In the present study, we found that the ice nucleation-active bacteria Xanthomonas campestris significantly altered anisotropic ice growth rate. Results of ice growth experiments in the presence of X. campestris showed that this bacterium decreased the ice crystal growth rate in the c-axis, whereas it increased growth rates in directions normal to the c-axis. These results indicate that these alterations in anisotropic growth rate are the result of selective binding of bacterial ice-nucleating proteins along the {0 0 0 1} basal plane.

    PubMed

    Morse, Dennis C; Henck, Judith W; Bailey, Steven A

    2016-04-01

    Pregabalin was administered to pregnant Wistar rats during organogenesis to evaluate potential developmental toxicity. In an embryo-fetal development study, compared with controls, fetuses from pregabalin-treated rats exhibited increased incidence of jugal fused to maxilla (pregabalin 1250 and 2500 mg/kg) and fusion of the nasal sutures (pregabalin 2500 mg/kg). The alterations in skull development occurred in the presence of maternal toxicity (reduced body weight gain) and developmental toxicity (reduced fetal body weight and increased skeletal variations), and were initially classified as malformations. Subsequent investigative studies in pregnant rats treated with pregabalin during organogenesis confirmed the advanced jugal fused to maxilla, and fusion of the nasal sutures at cesarean section (gestation day/postmating day [PMD] 21) in pregabalin-treated groups. In a study designed to evaluate progression of skull development, advanced jugal fused to maxilla and fusion of the nasal sutures was observed on PMD 20-25 and PMD 21-23, respectively (birth occurs approximately on PMD 22). On postnatal day (PND) 21, complete jugal fused to maxilla was observed in the majority of control and 2500 mg/kg offspring. No treatment-related differences in the incidence of skull bone fusions occurred on PND 21, indicating no permanent adverse outcome. Based on the results of the investigative studies, and a review of historical data and scientific literature, the advanced skull bone fusions were reclassified as anatomic variations. Pregabalin was not teratogenic in rats under the conditions of these studies.

  16. Climate Change Education Today in K-12: What's Happening in the Earth and Space Science Classroom?

    NASA Astrophysics Data System (ADS)

    Holzer, M. A.; National Earth Science Teachers Association

    2011-12-01

    Climate change is a highly interdisciplinary topic, involving not only multiple fields of science, but also social science and the humanities. There are many aspects of climate change science that make it particularly well-suited for exploration in the K-12 setting, including opportunities to explore the unifying processes of science such as complex systems, models, observations, change and evolution. Furthermore, this field of science offers the opportunity to observe the nature of science in action - including how scientists develop and improve their understanding through research and debate. Finally, climate change is inherently highly relevant to students - indeed, students today will need to deal with the consequences of the climate change. The science of climate change is clearly present in current science education standards, both at the National level as well as in the majority of states. Nonetheless, a significant number of teachers across the country report difficulties addressing climate change in the classroom. The National Earth Science Teachers Association has conducted several surveys of Earth and space science educators across the country over the past several years on a number of issues, including their needs and concerns, including their experience of external influences on what they teach. While the number of teachers that report external pressures to not teach climate change science are in the minority (and less than the pressure to not teach evolution and related topics), our results suggest that this pressure against climate change science in the K-12 classroom has grown over the past several years. Some teachers report being threatened by parents, being encouraged by administrators to not teach the subject, and a belief that the "two sides" of climate change should be taught. Survey results indicate that teachers in religious or politically-conservative districts are more likely to report difficulties in teaching about climate change than in

    Pacheco, H. A.; LaDue, N.; Moore, J. D.; Whitsett, S.

    2011-12-01

    Since 1994, the Albert Einstein Distinguished Science Educator Fellowship Act has brought Master K-12 STEM educators to Washington D.C. and Virginia for 11-month appointments in STEM-related Federal agencies and Congressional Offices. These top educators are leaders in their communities and often have years of experience working with government-funded researchers reaching out to the K-12 community. During their fellowship year, Einstein Fellows use their years of experience and expertise in to inform efforts and initiatives in the federal departments, directorates and offices to which they are assigned. The collaborative efforts of a group of NSF Einstein Fellows has led to the development of "Broader Impacts in the K-12 Community", a suite of experience-based recommendations and ideas designed to leverage grant resources and maximize effective partnerships between the research and K-12 communities. The goal of this presentation is to communicate best practices for researchers engaging in the realm of K-12 education from the perspective of educators. Challenges are highlighted and mapped to realistic solutions. Written originally as a panel talk to help NSF panel members consider feasible, high-quality K-12 broader impacts, this presentation has become an invaluable resource for principle investigators as they consider engaging with the K-12 community. While this presentation specifically addresses merit review components of NSF solicitations, these recommendations are relevant for any STEM initiatives that involve partnerships between scientists and teachers.

  3. Grapevine phenolic compounds in xylem sap and tissues are significantly altered during infection by Xylella fastidiosa.

    PubMed

    Wallis, Christopher M; Chen, Jianchi

    2012-09-01

    Pierce's disease of grapevine (PD), caused by the bacterial pathogen Xylella fastidiosa, remains a serious problem for grape production in California and elsewhere. This research examined induction of phenolic compounds in grapevines ('Thompson Seedless') infected with X. fastidiosa over a 6-month period. Two months postinoculation with X. fastidiosa, catechin, digalloylquinic acid, and astringin were found at greater levels in xylem sap; multiple catechins, procyanidins, and stilbenoids were found at greater levels in xylem tissues; and precursors to lignin and condensed tannins were found at greater levels in xylem cell walls. However, such large-scale inductions of phenolic compounds were not observed 4 months after inoculation. Six months after inoculation, infected plants had significantly reduced phenolic levels in xylem sap and tissues when compared with control plants, including lowered levels of lignin and condensed tannins. At 6 months, PD symptoms were severe in infected plants and most photosynthetic tissue was abscised. These results suggest that, even though grapevine hosts may initially respond to X. fastidiosa infections with increased production of phenolic compounds, ultimately, PD causes grapevines to enter a state of decline whereby diseased hosts no longer have the resources to support secondary metabolite production, including defense-associated phenolic compounds.

  4. Significant glial alterations in response to iron loading in a novel organotypic hippocampal slice culture model

    Healy, Sinead; McMahon, Jill; Owens, Peter; FitzGerald, Una

    2016-01-01

    Aberrant iron deposition in the brain is associated with neurodegenerative disorders including Multiple Sclerosis, Alzheimer’s disease and Parkinson’s disease. To study the collective response to iron loading, we have used hippocampal organotypic slices as a platform to develop a novel ex vivo model of iron accumulation. We demonstrated differential uptake and toxicity of iron after 12 h exposure to 10 μM ferrous ammonium sulphate, ferric citrate or ferrocene. Having established the supremacy of ferrocene in this model, the cultures were then loaded with 0.1–100 μM ferrocene for 12 h. One μM ferrocene exposure produced the maximal 1.6-fold increase in iron compared with vehicle. This was accompanied by a 1.4-fold increase in ferritin transcripts and mild toxicity. Using dual-immunohistochemistry, we detected ferritin in oligodendrocytes, microglia, but rarely in astrocytes and never in neurons in iron-loaded slice cultures. Moreover, iron loading led to a 15% loss of olig2-positive cells and a 16% increase in number and greater activation of microglia compared with vehicle. However, there was no appreciable effect of iron loading on astrocytes. In what we believe is a significant advance on traditional mono- or dual-cultures, our novel ex vivo slice-culture model allows characterization of the collective response of brain cells to iron-loading.

  6. Recent trends in vegetation greenness in China significantly altered annual evapotranspiration and water yield

    NASA Astrophysics Data System (ADS)

    Liu, Yibo; Xiao, Jingfeng; Ju, Weimin; Xu, Ke; Zhou, Yanlian; Zhao, Yuntai

    2016-09-01

    There has been growing evidence that vegetation greenness has been increasing in many parts of the northern middle and high latitudes including China during the last three to four decades. However, the effects of increasing vegetation greenness particularly afforestation on the hydrological cycle have been controversial. We used a process-based ecosystem model and a satellite-derived leaf area index (LAI) dataset to examine how the changes in vegetation greenness affected annual evapotranspiration (ET) and water yield for China over the period from 2000 to 2014. Significant trends in vegetation greenness were observed in 26.1% of China’s land area. We used two model simulations driven with original and detrended LAI, respectively, to assess the effects of vegetation ‘greening’ and ‘browning’ on terrestrial ET and water yield. On a per-pixel basis, vegetation greening increased annual ET and decreased water yield, while vegetation browning reduced ET and increased water yield. At the large river basin and national scales, the greening trends also had positive effects on annual ET and had negative effects on water yield. Our results showed that the effects of the changes in vegetation greenness on the hydrological cycle varied with spatial scale. Afforestation efforts perhaps should focus on southern China with larger water supply given the water crisis in northern China and the negative effects of vegetation greening on water yield. Future studies on the effects of the greenness changes on the hydrological cycle are needed to account for the feedbacks to the climate.

  7. Dietary Mannoheptulose Does Not Significantly Alter Daily Energy Expenditure in Adult Labrador Retrievers

    McKnight, Leslie L.; Root-McCaig, Jared; Wright, David; Davenport, Gary M.; France, James; Shoveller, Anna Kate

    2015-01-01

    Mannoheptulose (MH), a sugar found in avocados that inhibits glycolysis in vitro, has been preliminarily investigated as a novel food ingredient for dogs. This study aimed to determine the effects of dietary MH, delivered as an extract of un-ripened avocado, on energy expenditure (EE) in healthy adult Labrador Retriever dogs (total of 12 dogs, 26.99 ± 0.634 kg, 4.9 ± 0.2 y). The study was a double-blind, cross-over with each dog receiving both dietary treatments, control (CON) and MH (400 mg/kg of diet; 6 mg/kg BW), in random order. Resting and post-prandial (10 h) EE and respiratory quotient (RQ) were determined by indirect calorimetry (d 42). The following day, body composition was assessed using dual X-ray absorptiometry. Continuous activity monitoring was conducted using an Atical® accelerometer (d 43–47). A vastus lateralis muscle biopsy was obtained prior to the morning meal (d 49) and 4 h after consumption of their meal (d 56) to determine the protein content and phosphorylation of 5' adenosine monophosphate-activated protein kinase (AMPK). Diet did not affect body weight, resting EE or skeletal muscle AMPK phosphorylation. Dogs fed MH had significantly lower post-prandial RQ (p = 0.02) and ratio of fat to lean body mass (p = 0.02). Physical activity during light time periods (but not dark) was lower in dogs fed MH (p < 0.05) during weekends, but not on weekdays. These results suggest that MH affects energy balance of adult dogs, but that these effects are not dose dependent and not due to physical activity. PMID:26656105

    2015-12-01

    To understand soil microbial community stability and temporal turnover in response to climate change, a long-term soil transplant experiment was conducted in three agricultural experiment stations over large transects from a warm temperate zone (Fengqiu station in central China) to a subtropical zone (Yingtan station in southern China) and a cold temperate zone (Hailun station in northern China). Annual soil samples were collected from these three stations from 2005 to 2011, and microbial communities were analyzed by sequencing microbial 16S ribosomal RNA gene amplicons using Illumina MiSeq technology. Our results revealed a distinctly differential pattern of microbial communities in both northward and southward transplantations, along with an increase in microbial richness with climate cooling and a corresponding decrease with climate warming. The microbial succession rate was estimated by the slope (w value) of linear regression of a log-transformed microbial community similarity with time (time-decay relationship). Compared with the low turnover rate of microbial communities in situ (w=0.046, P<0.001), the succession rate at the community level was significantly higher in the northward transplant (w=0.058, P<0.001) and highest in the southward transplant (w=0.094, P<0.001). Climate warming lead to a faster succession rate of microbial communities as well as lower species richness and compositional changes compared with in situ and climate cooling, which may be related to the high metabolic rates and intense competition under higher temperature. This study provides new insights into the impacts of climate change on the fundamental temporal scaling of soil microbial communities and microbial phylogenetic biodiversity.

    The Center for Earthquake Research and Information at the University of Memphis has been committed to increasing awareness for Seismic Hazard, Earthquake Engineering, and Earth Science among Mid-America's policy-makers, engineers, emergency managers, the general public, and K-12 teachers and students for nearly three decades. During that time we have learned many lessons related to providing effective education and outreach programs, especially for K-12 students. The lessons learned from these activities may be particularly appropriate for other regions where large earthquakes occur infrequently but have disproportionately high consequence areas due to low attenuation of seismic waves. Effective education programs in these settings must provide a consistent message across many states to a wide variety of socio-economic groups and professional communities through the leveraged resources of various groups and agencies. It is also beneficial to hire and train staff with K-12 teaching experience to work directly K-12 education organizations, and science curriculum coordinators.

    Escherichia coli K-12 has the ability to migrate on semisolid media by means of swarming motility. A systematic and comprehensive collection of gene-disrupted E. coli K-12 mutants (the Keio collection) was used to identify the genes involved in the swarming motility of this bacterium. Of the 3,985 nonessential gene mutants, 294 were found to exhibit a strongly repressed-swarming phenotype. Further, 216 of the 294 mutants displayed no significant defects in swimming motility; therefore, the 216 genes were considered to be specifically associated with the swarming phenotype. The swarming-associated genes were classified into various functional categories, indicating that swarming is a specialized form of motility that requires a wide variety of cellular activities. These genes include genes for tricarboxylic acid cycle and glucose metabolism, iron acquisition, chaperones and protein-folding catalysts, signal transduction, and biosynthesis of cell surface components, such as lipopolysaccharide, the enterobacterial common antigen, and type 1 fimbriae. Lipopolysaccharide and the enterobacterial common antigen may be important surface-acting components that contribute to the reduction of surface tension, thereby facilitating the swarm migration in the E. coli K-12 strain.

    The effect of mechanical impact on the polymorphic transformation of mefenamic acid (MFA) and the formation of a solid dispersion of mefenamic acid, a poor glass forming/poorly-water soluble compound, with polyvinylpyrrolidone (PVP) K12 was investigated. The implication of solid dispersion formation on solubility enhancement of MFA, prepared by cryomilling, was investigated. Solid state characterization was conducted using powder X-ray diffraction (PXRD) and Fourier-transform infrared (FTIR) spectroscopy combined with crystal structure analysis. Apparent solubility of the mixtures in pH 7.4 buffer was measured. A calculation to compare the powder patterns and FTIR spectra of solid dispersions with the corresponding physical mixtures was conducted. Solid state characterization showed that (1) MFA I transformed to MFA II when pure MFA I was cryogenically milled (CM); and (2) MFA forms a solid dispersion when MFA was cryogenically milled with PVP K12. FTIR spectral analysis showed that hydrogen bonding facilitated by mechanical impact played a major role in forming solid dispersions. The apparent solubility of MFA was significantly improved by making a solid dispersion with PVP K12 via cryomilling. This study highlights the importance of cryomilling with a good hydrogen bond forming excipient as a technique to prepare solid dispersion, especially when a compound shows a poor glass forming ability and therefore, is not easy to form amorphous forms by conventional method.

    To maximize the contributions of nanotechnology to this society, at least 60 countries have put efforts into this field. In Taiwan, a government-funded K-12 Nanotechnology Programme was established to train K-12 teachers with adequate nanotechnology literacy to foster the next generation of Taiwanese people with sufficient knowledge in nanotechnology. In the present study, the Nanotechnology Attitude Scale for K-12 teachers (NAS-T) was developed to assess K-12 teachers' attitudes toward nanotechnology. The NAS-T included 23 Likert-scale items that can be grouped into three components: importance of nanotechnology, affective tendencies in science teaching, and behavioural tendencies to teach nanotechnology. A sample of 233 K-12 teachers who have participated in the K-12 Nanotechnology Programme was included in the present study to investigate the psychometric properties of the NAS-T. The exploratory factor analysis of this teacher sample suggested that the NAS-T was a three-factor model that explained 64.11% of the total variances. This model was also confirmed by the confirmatory factor analysis to validate the factor structure of the NAS-T. The Cronbach's alpha values of three NAS-T subscales ranged from 0.89 to 0.95. Moderate to strong correlations among teachers' NAS-T domain scores, self-perception of own nanoscience knowledge, and their science-teaching efficacy demonstrated good convergent validity of the NAS-T. As a whole, psychometric properties of the NAS-T indicated that this instrument is an effective instrument for assessing K-12 teachers' attitudes toward nanotechnology. The NAS-T will serve as a valuable tool to evaluate teachers' attitude changes after participating in the K-12 Nanotechnology Programme.

    Bacterial plasmids and phages encode the synthesis of toxic molecules that inhibit protozoan predation. One such toxic molecule is violacein, a purple pigmented, anti-tumour antibiotic produced by the Gram-negative soil bacterium Chromobacterium violaceum. In the current experiments a range of Escherichia coli K12 strains were genetically engineered to produce violacein and a number of its coloured, biosynthetic intermediates. A bactivorous predatory protozoan isolate, Colpoda sp.A4, was isolated from soil and tested for its ability to 'graze' on various violacein producing strains of E. coli K12. A grazing assay was developed based on protozoan "plaque" formation. Using this assay, E. coli K12 strains producing violacein were highly resistant to protozoan predation. However E. coli K12 strains producing violacein intermediates, showed low or no resistance to predation. In separate experiments, when either erythromycin or pentachlorophenol were added to the plaque assay medium, protozoan predation of E. coli K12 was markedly reduced. The inhibitory effects of these two molecules were removed if E. coli K12 strains were genetically engineered to inactivate the toxic molecules. In the case of erythromycin, the E. coli K12 assay strain was engineered to produce an erythromycin inactivating esterase, PlpA. For pentachlorophenol, the E. coli K12 assay strain was engineered to produce a PCP inactivating enzyme pentachlorophenol-4-monooxygenase (PcpB). This study indicates that in environments containing large numbers of protozoa, bacteria which use efflux pumps to remove toxins unchanged from the cell may have an evolutionary advantage over bacteria which enzymatically inactivate toxins.

    The mental health challenges of some vocations present a challenge for current intervention models. Bibliotherapy focused on transdiagnostic processes that might both prevent and alleviate a range of mental health distress could be an effective and practical approach. K-12 school personnel (N = 236; 91% female; 30-60 years old) responding to a wellness-oriented program announcement were randomized to receive an Acceptance and Commitment Therapy (ACT) self-help volume or to a waitlist. Three-fourths were above clinical cutoffs in general mental health, depression, anxiety, or stress. Participants read the book for two months, completed exercises and quizzes, and after post assessment were followed for 10 weeks; waitlist participants were then also given the book with two months to complete it. Overall, participants showed significant improvement in psychological health. Significant preventive effects for depression and anxiety were observed along with significant ameliorative effects for those in the clinical ranges of depression, anxiety and stress. Follow up general mental health, depression, and anxiety outcomes were related to the manner in which participants used the workbook and to post levels of psychological flexibility.

    Research highlights: {yields} Aging is associated with muscle atrophy and loss of muscle mass, known as the sarcopenia of aging. {yields} We demonstrate that age-related muscle atrophy is associated with marked changes in miRNA expression in muscle. {yields} Treating aged mice with the adipokine leptin significantly increased muscle mass and the expression of miRNAs involved in muscle repair. {yields} Recombinant leptin therapy may therefore be a novel approach for treating age-related muscle atrophy. -- Abstract: Age-associated loss of muscle mass, or sarcopenia, contributes directly to frailty and an increased risk of falls and fractures among the elderly. Aged mice and elderly adults both show decreased muscle mass as well as relatively low levels of the fat-derived hormone leptin. Here we demonstrate that loss of muscle mass and myofiber size with aging in mice is associated with significant changes in the expression of specific miRNAs. Aging altered the expression of 57 miRNAs in mouse skeletal muscle, and many of these miRNAs are now reported to be associated specifically with age-related muscle atrophy. These include miR-221, previously identified in studies of myogenesis and muscle development as playing a role in the proliferation and terminal differentiation of myogenic precursors. We also treated aged mice with recombinant leptin, to determine whether leptin therapy could improve muscle mass and alter the miRNA expression profile of aging skeletal muscle. Leptin treatment significantly increased hindlimb muscle mass and extensor digitorum longus fiber size in aged mice. Furthermore, the expression of 37 miRNAs was altered in muscles of leptin-treated mice. In particular, leptin treatment increased the expression of miR-31 and miR-223, miRNAs known to be elevated during muscle regeneration and repair. These findings suggest that aging in skeletal muscle is associated with marked changes in the expression of specific miRNAs, and that nutrient

    Adenoid cystic carcinoma (ACC) of the head and neck is a malignant tumor with poor long-term prognosis. Besides the recently identified MYB-NFIB fusion oncogene generated by a t(6;9) translocation, little is known about other genetic alterations in ACC. Using high-resolution, array-based comparative genomic hybridization, and massively paired-end sequencing, we explored genomic alterations in 40 frozen ACCs. Eighty-six percent of the tumors expressed MYB-NFIB fusion transcripts and 97% overexpressed MYB mRNA, indicating that MYB activation is a hallmark of ACC. Thirty-five recurrent copy number alterations (CNAs) were detected, including losses involving 12q, 6q, 9p, 11q, 14q, 1p, and 5q and gains involving 1q, 9p, and 22q. Grade III tumors had on average a significantly higher number of CNAs/tumor compared to Grade I and II tumors (P = 0.007). Losses of 1p, 6q, and 15q were associated with high-grade tumors, whereas losses of 14q were exclusively seen in Grade I tumors. The t(6;9) rearrangements were associated with a complex pattern of breakpoints, deletions, insertions, inversions, and for 9p also gains. Analyses of fusion-negative ACCs using high-resolution arrays and massively paired-end sequencing revealed that MYB may also be deregulated by other mechanisms in addition to gene fusion. Our studies also identified several down-regulated candidate tumor suppressor genes (CTNNBIP1, CASP9, PRDM2, and SFN) in 1p36.33-p35.3 that may be of clinical significance in high-grade tumors. Further, studies of these and other potential target genes may lead to the identification of novel driver genes in ACC.

  1. Brain Based Learning: K-12 Teachers' Preferred Methods of Science Instruction

    The purpose of this quantitative study was to investigate Brain Based Learning (BBL) techniques in teaching science. Participants included 216 K-12, full-time, regular education teachers from 8 Northeast Tennessee school systems who taught at least 1 science class. Specifically this research was guided by 7 research questions on teachers' perceptions and practices in teaching science. Data were collected by a survey that consisted of 82 statements where teachers rated their level of agreement and was distributed online via Survey Monkey. The first portion of my survey included demographic identifiers, teachers' knowledge of the term BBL, and inquiries regarding science background and training. The remainder of the statements were focused on teachers' perceptions and practices of BBL strategies in teaching science. The final item was open-ended and allowed teachers to share comments related to teaching science. For statements 6-81, participants responded by using a 5-point Likert scale that ranged from 1 (strongly disagree) to 5 ( strongly agree). Quantitative data were analyzed with a series of independent samples t tests, one-way analysis of variance tests, and a Pearson correlation coefficient. The results of the study indicate that teachers' perceptions are positively correlated to their self-reported practices. Females, in general, and elementary teachers tend to practice BBL strategies in teaching science significantly more than other subgroups.

    How do you design a site that will meet the needs of teachers and students and actually be used in the classroom, when there are millions of Web sites competing for their attention? Many science centers, including the National Snow and Ice Data Center (NSIDC), strive to meet the informational needs of the general public without specifically targeting educators, who desire Web material that is prepackaged for use in the classroom. In creating a new educational Web site, we wanted to develop our materials to ensure the content is used by educators in the classroom, seeking collaborators beyond our organization. Noting a lack of on-line information geared to the public on frozen ground and its significance to global climate, we are developing a Web site, All About Frozen Ground, to assist K-12 students, teachers and the public to understand frozen ground, its relation to the climate system, and its impact on engineering in cold regions. NSIDC partnered with scientists, writers, teachers, and an evaluator to make certain the content meets science standards and the requirements and interests of teachers and their students. Following accepted evaluation procedures, we will test the material in the classroom and through on-line surveys, and use the feedback to improve the Web site and its accompanying educational materials.

    Microbes, as one of the primary producers of the biosphere, play an important role in ecosystems. Exploring the mechanism of adaptation and resistance of microbial population to various environmental factors has come into focus in the fields of modern microbial ecology and molecular ecology. However, facing the increasingly serious problem of acoustic pollution, very few efforts have been put forth into studying the relation of single cell organisms and sound field exposure. Herein, we studied the biological effects of sound exposure on the growth of E. coli K-12 with different acoustic parameters. The effects of sound exposure on the intracellular macromolecular synthesis and cellular morphology of E. coli K-12 were also analyzed and discussed. Experimental results indicated that E. coli K-12 exposed to sound waves owned a higher biomass and a faster specific growth rate compared to the control group. Also, the average length of E. coli K-12 cells increased more than 27.26%. The maximum biomass and maximum specific growth rate of the stimulation group by 8000 Hz, 80dB sound wave was about 1.7 times and 2.5 times that of the control group, respectively. Moreover, it was observed that E. coli K-12 can respond rapidly to sound stress at both the transcriptional and posttranscriptional levels by promoting the synthesis of intracellular RNA and total protein. Some potential mechanisms may be involved in the responses of bacterial cells to sound stress. PMID:27077011

    Exposing K-12 students to cutting edge science that impacts their daily lives can bring classroom lessons to life. Citizen-science projects are an excellent way to bring high-level science to the classroom and help satisfy one of the cornerstone concepts of the Next Generation Science Standards (NGSS), "engaging in practices that scientists and engineers actually use." This can be a daunting task for teachers who may lack the background or resources to integrate these projects into the classroom. This is where scientific societies such as the American Society for Microbiology (ASM) can play a critical role. ASM encourages its members to engage with the K-12 community by providing networking opportunities and resources for ASM members and K-12 teachers to work together to bring microbiology into the classroom.

  7. K-12 Teacher Understanding of Energy Conservation: Conceptual Metaphor, Dissipation, and Degradation

    NASA Astrophysics Data System (ADS)

    Daane, Abigail R.

    In K-12 educational settings, conservation of energy is typically presented in two ways: the conservation of energy principle (energy is neither created nor destroyed) and the sociopolitical need to conserve energy (we guard against energy being used up). These two meanings of conservation typically remain disconnected from each other and can appear contradictory, even after instruction. In an effort to support teachers in building robust understandings of energy from their existing knowledge, I designed a study to investigate the productive ideas in K-12 teachers' conversations about energy. A micro-analysis of discourse, gestures, and artifacts of professional development courses revealed teachers' productive ideas about three aspects of energy: conceptual metaphor, dissipation and degradation. In learning about energy, K-12 teachers come to use conceptual metaphors in their own language and value attending to students' metaphorical language as a means of formative assessment. Teachers' conversations about dissipation suggest that apparent difficulties with energy conservation may have their roots in a strong association between forms of energy (thermal) and their perceptible indicators (warmth). Teachers address this challenge by employing an exaggeration strategy to locate the dissipated thermal energy, making the energy indicator perceptible. Finally, teachers' unprompted statements about sociopolitical aspects of energy are related to both statements from the NGSS and aspects of energy degradation. I conclude that energy conservation can be better taught and learned in K-12 Education by: 1) understanding and applying conceptual metaphors about energy in K-12 settings, 2) using prior experiences to better understand dissipative energy processes involving imperceptible thermal energy, thereby understanding how energy conservation applies in all situations, and 3) connecting productive ideas about sociopolitical aspects of energy to canonical physics.

    Recurrent pharyngo-tonsillar infections caused by group A beta-hemolytic streptococci (GABHS) occur frequently in young children, and the treatment of these infections contributes substantially to the total current requirement for antibiotic prescribing. Our study goal was to assess through a retrospective observational analysis whether the administration of the oral probiotic, Streptococcus salivarius K12 (SsK12), could reduce the occurrence of GABHS pharyngo-tonsillar infections in children who had a recent history of recurrent episodes of these infections. Twelve primary care pediatricians identified, through their databases, a total of 130 children who had experienced recurrent GABHS pharyngo-tonsillar infections over a period of at least 6–12 months prior to their inclusion in the study. Of these children, 76 then undertook a 90-day program requiring once-a-day dosing with a commercially available (Bactoblis) lozenge containing SsK12. No probiotic supplement was given to the remaining 54 (control) children. Each subject was monitored for the occurrence of GABHS pharyngo-tonsillitis and also for acute otitis media, bronchitis, sinusitis, and bronchopneumonia for at least 12 months following their entry to the study. Even 9 months after the use of SsK12 had been stopped, the probability of new GABHS infections was significantly lower (P>0.001) when compared to the period before dosing commenced. When compared to the untreated children, those taking SsK12 appear to have had significantly fewer GABHS infections both during the 90-day period of prophylaxis and during the following 9 months (P<0.001). These observations are supportive of the use of probiotic SsK12 for the control of recurrent GABHS pharyngo-tonsillar infections in children, and as an associated benefit, the use of this probiotic could lead to reduced antibiotic consumption. Follow-up controlled prospective studies should now be initiated in order to further establish the efficacy of this newly

    Today's scientist is frequently asked to find ways to identify "broader impacts" in their research proposals, in addition to proposing a compelling project on the forefront of research. Broader impact requirements are designed to ensure that research results have a positive impact for the society at large, which in most cases is the source of the support for the research in the first place. Indeed, most research solicitations from funding agencies require components of the proposal that will benefit society and spread knowledge beyond the scientist's peer group. Developing these program elements in an efficient and effective way can be daunting to a scientist who is typically focused on their research and may not have expertise nor an extensive network in the education and outreach arena. Geoscientists seeking to make a significant contribution in K-12, working with teachers and students in a school setting, should develop an understanding of the state of Earth and space science education today across the country, develop partnerships with education and outreach specialists working in the K-12 setting, and learn from best practices to optimize their efforts. Where is Earth and space science taught today in K-12? Is it required? Is it an elective? Is it even in the curriculum? What is the background of the teachers teaching in this subject area? What resources do they need? What are science standards, and is Earth and space science tested in the schools? What are the key approaches scientists can use to have optimal positive impact in the K-12 setting?

NNIN's education and outreach programs are large and varied and includes outreach to the K-12 community in the form of professional development workshops and school programs. Two important components of nanoscale science education are understanding size and scale and the tools used in nanoscale science and engineering (NSE). As part of our K-12 endeavors, we educate K-12 students and teachers about the tools of nanoscience by providing experiences with the Hitachi TM 3000 tabletop Scanning Electron Microscope (SEM). There are three of these across the network that are used in education and outreach. This paper will discuss approaches we use to engage the K-12 community at NNIN's site at Georgia Institute of Technology to understand size and scale and the applications of a variety of microscopes to demonstrate the imaging capabilities of these to see both the micro and nano scales. We not only use the tabletop SEM but also include USB digital microscopes, a Keyence VHX- 600 Digital Microscope, and even a small lens used with smart phones. The goal of this outreach is to educate students as well as teachers about the capabilities of the various instruments and their importance at different size scales.
