2013-12-01

The Science Education Resource Center (SERC) has created a portal to information for K12 educators to provide high-quality grade level appropriate materials from a wide variety of projects and topics. These materials were compiled across the SERC site, showcasing materials that were created for, or easily adaptable to, K12 classrooms. This resource will help support implementation of Next Generation Science Standards by assisting educators in finding innovative resources to address areas of instruction that are conceptually different than previous national and state science standards. Specifically, the K12 portal assists educators in learning about approaches that address the cross-cutting nature of science concepts, increasing students quantitative reasoning and numeracy skills, incorporating technology such as GIS in the classroom, and by assisting educators of all levels of K12 instruction in using relevant and meaningful ways to teach science concepts. The K12 portal supports educators by providing access to hundreds of teaching activities covering a wide array of science topics and grade levels many of which have been rigorously reviewed for pedagogic quality and scientific accuracy. The portal also provides access to web pages that enhance teaching practices that help increase student's system thinking skills, make lectures interactive, assist instructors in conducting safe and effective indoor and outdoor labs, providing support for teaching energy and climate literacy principles, assisting educators in addressing controversial content, provide guidance in engaging students affective domain, and provides a collection of tools for making teaching relevant in 21st century classrooms including using GIS, Google Earth, videos, visualizations and simulations to model and describe scientific concepts. The portal also provides access to material for specific content and audiences by (1) Supporting AGIs 'Map your World' week to specifically highlight teaching

Instituting a standards-based K--12 science curriculum supplement program at the National Institutes of Health: A case study

NASA Astrophysics Data System (ADS)

Witherly, Jeffre

Research on student achievement indicates the U.S. K-12 education system is not adequately preparing American students to compete in the 21st century global economy in the areas of science and mathematics. Congress has asked the scientific entities of the federal government to help increase K-12 science learning by creating standards-based learning tools for science classrooms as part of a "voluntary curriculum." One problem facing federal entities, such as the National Institutes of Health (NIH), is the need to create science-learning tools that conform to the National Science Education Standards (NSES) for curriculum materials and, therefore, are standards-based and applicable to the K-12 curriculum. This case study sought to better understand the change process at one federal agency as it went from producing K-12 learning tools that were educational in nature to a program that produced K-12 standards-based learning tools: the NIH Science Curriculum Supplement Program (NIH SCSP). The NIH SCSP was studied to gain insight into how this change in educational approach occurred, what factors enabled or inhibited the change process, and what the long-term benefits of the NIH SCSP are to the NIH. Kurt Lewin's three-step theory of change guided data gathering and data analysis. Semi-structured interviews and programmatic document review served as the major data gathering sources. Details describing the process of organizational change at the NIH were revealed during analysis of these data following the coding of interview transcripts and written record documents. The study found the process of change at the NIH proceeded in a manner generally predicted by the Lewinian change model. Enablers to the change were cost-sharing with individual institutes, support of senior leadership, and crediting the role of individual institutes prominently in each supplement. The cost of creating a supplement was reported as the single inhibitor to the program. This case study yielded a

2013-12-01

For the past six years, a multi-institution effort has undertaken a broad glaciological and climate research project in Denali National Park. Most recently, two ~208 m long surface to bedrock ice cores were recovered from the Mt. Hunter plateau with supporting geophysical and weather data collected. Twenty two individuals have participated in the field program providing thousands of person-hours towards completing our research goals. Technical and scientific results have been disseminated to the broader scientific community through dozens of professional presentations and six peer-reviewed publications. In addition, we have pursued the development of interactive computer applications that use our results for educational purposes, publically available fact sheets through Denali National Park, and most recently, with assistance from PolarTREC and other affiliations, the development of a children's book and roll-out of K-8 science curriculum based on this project. The K-8 curriculum will provide students with an opportunity to use real scientific data to meet their educational requirements through alternative, interactive, and exciting methods relative to more standard educational programs. Herein, we present examples of this diverse approach towards incorporating polar research into K-12 STEM classrooms.

The aim of the scheme was to determine consistency of histopathological reporting in the United Kingdom National Breast Screening Programme. This external quality assessment scheme involved 51 sets of 12 slides which were circulated to 186-251 pathologists at intervals of 6 months for 3 years. Participants recorded their diagnoses on standard reporting forms, which were submitted to the U.K. National Cancer Screening Evaluation Unit for analysis. A high level of consistency was achieved in diagnosing major categories of breast disease including invasive carcinoma and the important borderline lesions, radial scar and ductal carcinoma in situ (DCIS), the latter exceeding a national target set prior to the onset of the scheme. Atypical hyperplasia (AH) was reported with much less consistency although, where it was the majority opinion, over 86% of diagnoses were of benign disorders and only 14% were of DCIS. Inconsistency was encountered in subtyping and measuring DCIS, the former apparently due to current uncertainties about classification and the latter to poor circumscription, variation in size in different sections and merging with zones of AH. Reporting prognostic features of invasive carcinomas was variable. Measurement of size was achieved with adequate consistency except in a small number of very poorly circumscribed tumours. Grading and subtyping were inconsistent although the latter was not specifically tested and will be the subject of future study. Members of the National Coordinating Group achieved greater uniformity than the remainder of the participants in all diagnostic categories, but both groups experienced similar types of problem. Our findings suggest that participation in the scheme improves diagnostic consistency. In conclusion, consistency in diagnosing invasive carcinoma and radial scar is excellent, and good in DCIS, but improvements are desirable in diagnosing atypical hyperplasia, classifying DCIS and reporting certain prognostic features of

The Lewis Center for Educational Research (LCER) and the Jet Propulsion Laboratory (JPL) collaborate in a K-12 educational project in which students conduct observations for several research programs led by radio astronomers. The Goldstone-Apple Valley Radio Telescope (GAVRT) program provides participating teachers with curriculum elements, based on the students' observing experiences, which support national and state academic standards. The current program is based on 2.2-GHz and 8.4-GHz radiometric observations of variable sources. The research programs monitor Jupiter, Uranus, and a selected set of quasars. The telescope is a decommissioned NASA Deep Space Network antenna at Goldstone, California. In the next three years, a second telescope will be added. This telescope will at least operate at the above frequencies as well as 6 GHz and 12 GHz. Possibly, it will operate in a continuous band from 1.2 GHz to 14 GHz. In either case, the telescope will be able to observe at least the 6.6-GHz and 12.2-GHz methanol maser lines. The success of the GAVRT program depends critically on the participation of scientists committed to the research who have the ability and enthusiasm for interacting with K-12 students, typically through teleconferences. The scientists will initially work with the LCER staff to create curriculum elements around their observing program.

Hepatitis C virus (HCV) recombinant form RF1_2k/1b is common in ethnic Georgians. This chimera virus contains genomic fragments of genotype 2 and genotype 1 and is misclassified as genotype 2 by standard genotyping. We aimed to identify RF1_2k/1b strains among genotype 2 patients and assess its impact on treatment outcomes. The study included 148 patients with HCV genotype 2 as determined by 5-untranslated region/core genotyping assay. RF1_2k/1b was identified by sequencing the non-structural protein 5B region. Patients were treated within the national hepatitis C elimination program with sofosbuvir/ribavirin (SOF/RBV), interferon (IFN)/SOF/RBV, or ledipasvir (LDV)/SOF/RBV. Of 148 patients, 103 (69.5%) had RF1_ 2k/1b. Sustained virologic response (SVR) data was available for 136 patients (RF1_ 2k/1b, n = 103; genotype 2, n = 33). Sustained virologic response was achieved in more genotype 2 patient than in RF1_2k/1b patients (97.0% vs. 76.7%, P = 0.009). Twelve weeks of LDV/SOF/RBV treatment was highly effective (100% SVR) in both genotypes. Among RF1_2k/1b patients, LDV/SOF/RBV for 12 weeks was superior (100% SVR) to SOF/RBV for 12 weeks (56.4%, P < 0.0001) or 20 weeks (79.2%, P = 0.05). Twelve weeks of IFN/SOF/RBV also showed better response than SOF/RBV for 12 weeks (88.9% vs. 56.4%, P = 0.02) in these patients. High prevalence of the RF1_2k/1b strain can significantly affect treatment outcomes. Treatment with IFN/SOF/RBV and especially LDV/SOF/RBV ensured significantly higher SVR in patients infected with RF1_2k/1b strain compared to standard HCV genotype 2 treatment with SOF/RBV. There is a need to reassess existing methods for the management of HCV genotype 2 infections, especially in areas with high prevalence of the RF1_2k/1b strain. © 2017 The Japan Society of Hepatology.

Overcoming Constraints of Building Successful Partnerships Incorporating STEM Research Into K-12 Classrooms

The Initiating New Science Partnerships in Rural Education (INSPIRE) program at Mississippi State University (MSU), funded by the NSF Graduate STEM Fellows in K-12 Education (GK12) program, focuses on the advancement of Earth and Space science education in K-12 classrooms. INSPIRE is currently in its second year of partnering ten graduate students from the STEM fields of Geosciences, Engineering and Chemistry at MSU with five teachers from local, rural school districts. The five year project serves to increase inquiry and technology experiences in science and math while enhancing graduate student's communication skills as they create interactive lessons linking their STEM research focus to the state and national standards covered in the classrooms. Each graduate student is responsible for the development of two lessons each month of the school year that are then published on the INSPIRE project webpage, www.gk12.msstate.edu, where they are a free resource for any K-12 classroom teacher seeking innovative activities for their classrooms. Many of the participating teachers and graduate students share activities developed with non-participating teachers, expanding INSPIRE's outreach throughout the local community. Numerous challenges were met during the formation of the program as well as throughout the first year in which the project management team worked together to find solutions ensuring that INSPIRE maintained successful partnerships for all involved. Proposed solutions of the following key components were identified by INSPIRE through the development, implementation, and continuous evaluation (internal and external) of the first year of the program as areas that can pose challenges to the construction of strong relationships between STEM research and K-12 classrooms: initializing the partnerships with the K-12 classrooms and STEM graduate fields at the university; maintaining strong partnerships; providing appropriate training and support; developing sound

With new career openings in the geosciences expected and a large number of presently employed geoscientists retiring in the next decade there is a critical need for a new cadre of geoscientists to fill these positions. A project funded by the National Science Foundation titled K-12 Students, Teachers, Parents, Administrators and Higher Education Faculty: Partners Helping Rural Disadvantaged Students Stay on the Pathway to a Geoscience Career involving Wright State University and the Ripley, Lewis, Union, Huntington k-12 school district in Appalachian Ohio took led to dozens of seventh and eighth grade students traveling to Sandy Hook, New Jersey for a one week field experience to study oceanography with staff of the New Jersey Sea Grant Consortium. Teachers, parent chaperones, administrators and university faculty accompanied the students in the field. Teachers worked alongside their students in targeted professional development during the weeklong field experience. During the two academic years of the project, both middle school and high school teachers received professional development in Earth system science so that all students, not just those that were on the summer field experience could receive enhanced science learning. All ninth grade high school students were given the opportunity to take a high school/college dual credit Earth system science course. Community outreach provided widespread knowledge of the project and interest among parents to have their children participate. In addition, ninth grade students raised money themselves to fund a trip to the International Field Studies Forfar Field Station on Andros Island, Bahamas to study a tropical aquatic system. Students who before this project had never traveled outside of Ohio are currently discussing ways that they can continue on the pathway to a geoscience career by applying for internships for the summer between their junior and senior years.

The University Scientist's Role in Promoting Collaborative K-12 Professional Development

NASA Astrophysics Data System (ADS)

Schuster, D.; Brown, L. L.; Carlsen, W. S.

2004-12-01

Comprehensive K-12 science teacher professional development is dependent upon the successful interaction between the university and K-12 communities (National Research Council, 2001), which can be realized through partnerships between university scientists and K-12 science teachers. This paper will identify some best practices of university scientists in the professional development of science teachers, first by citing the professional development and science education literature (Loucks-Horsley, Hewson, Love, & Stiles, 1998; National Research Council, 1996a, 1996b), and then by highlighting how these best practices were actualized in summer workshops for science educators offered at Penn State. Each summer the Pennsylvania Space Grant Consortium supports seven one-week courses for secondary science teachers taught by university scientists from disciplines representative of NASA's research interests. Approximately 100 teachers enroll in these two-credit, graduate-level workshops from a variety of locations and contexts throughout the United States. These summer courses share a number of important features (duration, general format, teacher recruitment and admission, location, number of participants, etc.), making them a unique dataset for comparative research on science teacher professional development. By recognizing the role of university scientists relating to both practice and standards of professional development, we identify areas in which teachers could be empowered to lead and, alternatively, where scientists and administrators should improve and continue to direct-- both supporting a culture of collaboration that builds K-12 science teacher capacity (Fullan, 2001, 2003; Hawley & Valli, 1999). In our observations and analysis of the evaluations, three best practices, as defined by the literature, appeared to distinguish the exceptional workshops: First, teachers give high marks and make affirmative comments about workshops with clearly presented curricular

Engineering Education in K-12 Schools

NASA Astrophysics Data System (ADS)

Spence, Anne

2013-03-01

Engineers rely on physicists as well as other scientists and mathematicians to explain the world in which we live. Engineers take this knowledge of the world and use it to create the world that never was. The teaching of physics and other sciences as well as mathematics is critical to maintaining our national workforce. Science and mathematics education are inherently different, however, from engineering education. Engineering educators seek to enable students to develop the habits of mind critical for innovation. Through understanding of the engineering design process and how it differs from the scientific method, students can apply problem and project based learning to solve the challenges facing society today. In this talk, I will discuss the elements critical to a solid K-12 engineering education that integrates science and mathematics to solve challenges throughout the world.

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.

Nucleoli in human early erythroblasts (K2, K1, K1/2 cells).

PubMed

Smetana, K; Jirásková, I; Klamová, H

2005-01-01

Human early erythroid precursors classified according to the nuclear size were studied to provide information on nucleoli in these cells using simple cytochemical procedures for demonstration of RNA and proteins of silver-stained nucleolar organizers. K2 cells with nuclear diameter larger than 13 microm and K1 cells with nuclear diameter larger than 9 microm corresponding to proerythroblasts and macroblasts (large basophilic erythroblasts) mostly possessed large irregularly shaped nucleoli with multiple fibrillar centres representing "active nucleoli". K1/2 cells with nuclear diameter smaller than 9 microm corresponding to small basophilic erythroblasts were usually characterized by the presence of micronucleoli representing "inactive nucleolar types". On the other hand, a few K1/2 cells contained large nucleoli with multiple fibrillar centres similar to those present in K2 cells and thus appeared as "microproerythroblasts". The nucleolar asynchrony expressed by the presence of large irregularly shaped nucleoli with multiple nucleoli (active nucleoli) and ring-shaped nucleoli (resting nucleoli) in one and the same nucleus of K2 or K1 cells was not exceptional and might reflect a larger resistance of these cells to negative factors influencing the erythropoiesis. The intranucleolar translocation of silver-stained nucleolus organized regions was noted in K2 cells and might indicate the premature aging of these cells without further differentiation. More studies, however, are required in this direction.

CESAME: Providing High Quality Professional Development in Science and Mathematics for K-12 Teachers

NASA Astrophysics Data System (ADS)

Hickman, Paul

2002-04-01

It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

Ras gene plays an important role in the extra- and intra-cellular signal transduction pathway. It mediates series cascade reactions, and eventually actives transcriptional factors in nucleus. It is unknown on the mechanism of carcinogenesis of Ras gene in endometrial carcinoma, though K-ras mutant is very common in endometrial atypical hyperplasia and carcinoma. On basis of discovering the mutation in 12th codon of K-ras in endometrial carcinoma cell line, HEC-1A, we explored the carcinogenesis and molecular mechanism of mutant-type [12Asp] K-ras4B gene. (1) Full-length [12Asp]K-ras4B cDNA was amplified with RT-PCR, then inserted into pcDI eukaryotic expressive vector. (2) Morphological change, growth kinetics in vitro and tumorigencity in nude mice in vivo after-before transfection were observed. (3) To test the cell growth kinetics by methyl thiazolium tetrazolium (MTT) and [3H]thymidine incorporation method. (1) The authors have successfully constructed eukaryotic expression plasmid pcDI-[12Asp] K-ras4B; (2) To confirm that [12Asp] K-ras4B mutant can trigger the neoplastic transformation of NIH3T3 cells by test in vitro and in vivo. (3) After pMCV-RasN17 plasmid, a Ras mutant were transfected into pcDI-[12Asp] K-ras4B cells, the growth of this cell were restrained significantly in comparison with control group. (4) These findings indicate the expression of RafS621A resulted in remarkable inhibition in proliferation of pcDI-[12Asp]K-ras4B cell (P < 0.05). However, RafCAAX mutant can enhance pcDI-[12Asp]K-ras4B cell growth (P < 0.05). (1) [12Asp]K-ras4B gene alone is able to cause neoplastic transformation in NIH3T3 cells in vitro and in vivo. (2) [12Asp]K-ras4B-induced NIH3T3 cells neoplastic transformation required Raf signaling pathway.

Interactive Teaching as a Recruitment and Training Tool for K-12 Science Teachers

NASA Astrophysics Data System (ADS)

Rosenberg, J. L.

2004-12-01

The Science, Technology, Engineering, and Mathematics Teacher Preparation (STEMTP) program at the University of Colorado has been designed to recruit and train prospective K-12 science teachers while improving student learning through interactive teaching. The program has four key goals: (1) recruit undergraduate students into K-12 science education, (2) provide these prospective teachers with hands-on experience in an interactive teaching pedagogy, (3) create an intergrated program designed to support (educationally, socially, and financially) and engage these prospective science teachers up until they obtain liscensure and/or their masters degree in education, and (4) improve student learning in large introductory science classes. Currently there are 31 students involved in the program and a total of 72 students have been involved in the year and a half it has been in existence. I will discuss the design of the STEMTP program, the success in recruiting K-12 science teachers, and the affect on student learning in a large lecture class of implementing interactive learning pedagogies by involving these prospective K-12 science teachers. J. L. Rosenberg would like to acknowledge the NSF Astronomy and Astrophysics Fellowship for support for this work. The course transformation project is also supported by grants from the National Science Foundation.

Are K-12 learners motivated in physical education? A meta-analysis.

PubMed

Chen, Senlin; Chen, Ang; Zhu, Xihe

2012-03-01

Previous studies devoted to K-12 learner motivation in physical education share a general assumption that students may lack motivation. This meta-analytic study examined published original studies (n = 79) to determine students' motivation level and the association between motivation and outcomes. Original means of motivation measures were converted and aggregated to determine motivation levels. Correlation effect sizes were calculated to determine the association between motivation and outcome measures. The analyses revealed that K-12 students are motivated regardless of the theoretical constructs used in the studies (M > 50). The correlation effect sizes (r = .20-.30, p < .05) indicate a weak association between motivation and outcome. The findings suggest a need to involve meaningful learning and pedagogy variables in motivation research.

Comparative analysis of envelope proteomes in Escherichia coli B and K-12 strains.

PubMed

Han, Mee-Jung; Lee, Sang Yup; Hong, Soon Ho

2012-04-01

Recent genome comparisons of E. coli B and K-12 strains have indicated that the makeup of the cell envelopes in these two strains is quite different. Therefore, we analyzed and compared the envelope proteomes of E. coli BL21(DE3) and MG1655. A total of 165 protein spots, including 62 nonredundant proteins, were unambiguously identified by two-dimensional gel electrophoresis and mass spectrometry. Of these, 43 proteins were conserved between the two strains, whereas 4 and 16 strain-specific proteins were identified only in E. coli BL21(DE3) and MG1655, respectively. Additionally, 24 proteins showed more than 2-fold differences in intensities between the B and K-12 strains. The reference envelope proteome maps showed that E. coli envelope mainly contained channel proteins and lipoproteins. Interesting proteomic observations between the two strains were as follows: (i) B produced more OmpF porin with a larger pore size than K-12, indicating an increase in the membrane permeability; (ii) B produced higher amounts of lipoproteins, which facilitates the assembly of outer membrane beta-barrel proteins; and (iii) motility- (FliC) and chemotaxis-related proteins (CheA and CheW) were detected only in K-12, which showed that E. coli B is restricted with regard to migration under unfavorable conditions. These differences may influence the permeability and integrity of the cell envelope, showing that E. coli B may be more susceptible than K-12 to certain stress conditions. Thus, these findings suggest that E. coli K-12 and its derivatives will be more favorable strains in certain biotechnological applications, such as cell surface display or membrane engineering studies.

With the support of the Department of Energy, the National Science Teachers Association and the National Oceanic and Atmospheric Administration, Imaginary Lines Inc. (dba Sally Ride Science) delivered a highly successful 2-day conference to 165 K-12 educators on climate change. The event took place on July 23rd and 24th, 2008 at the NOAA facility in Silver Spring, MD. The conference celebrated the 25th anniversary of Dr. Sally Ride’s first flight into space in 1983 and examined how our understanding of Earth has changed in those 25 years. One the first day of the conference, participants heard a keynote talk deliveredmore » by Dr. Sally Ride, followed by presentations by well-known climate change scientists: Dr. Richard Somerville, Dr. Inez Fung and Dr. Susan Solomon. These sessions were concurrently webcast and made available to educators who were unable to attend the conference. On the second day of the conference, participants attended breakout sessions where they performed climate change activities (e.g. “Neato Albedo!”, “Greenhouse in a Bottle”, “Shell-Shocked”) that they could take back to their classrooms. Additional break-out sessions on using remote sensing images to illustrate climate change effects on Earth’s surface and how to address the climate change debate, were also offered. During lunch, participants attended an Educator Street Fair and had the opportunity to interact with representatives from NOAA, NASA, the EPA, NEEF and the JASON project. A follow-up evaluation survey was administered to all conference attendees immediately following the conference to evaluate its effectiveness. The results of this survey were overwhelmingly positive. The conference materials: presentation Power Points, workshop handouts and activities were available for teachers to download after the conference from the Sally Ride Science website. In summary, the approximately $55K support for the Department of Energy was used to help plan, deliver and

The minor spliceosomal protein U11/U12-31K is an RNA chaperone crucial for U12 intron splicing and the development of dicot and monocot plants.

U12 intron-specific spliceosomes contain U11 and U12 small nuclear ribonucleoproteins and mediate the removal of U12 introns from precursor-mRNAs. Among the several proteins unique to the U12-type spliceosomes, an Arabidopsis thaliana AtU11/U12-31K protein has been shown to be indispensible for proper U12 intron splicing and for normal growth and development of Arabidopsis plants. Here, we assessed the functional roles of the rice (Oryza sativa) OsU11/U12-31K protein in U12 intron splicing and development of plants. The U11/U12-31K transcripts were abundantly expressed in the shoot apical meristems (SAMs) of Arabidopsis and rice. Ectopic expression of OsU11/U12-31K in AtU11/U12-31K-defecient Arabidopsis mutant complemented the incorrect U12 intron splicing and abnormal development phenotypes of the Arabidopsis mutant plants. Impaired cell division activity in the SAMs and inflorescence stems observed in the AtU11/U12-31K-deficient mutant was completely recovered to normal by the expression of OsU11/U12-31K. Similar to Arabidopsis AtU11/U12-31K, rice OsU11/U12-31K was determined to harbor RNA chaperone activity. Collectively, the present findings provide evidence for the emerging idea that the U11/U12-31K protein is an indispensible RNA chaperone that functions in U12 intron splicing and is necessary for normal development of monocotyledonous plants as well as dicotyledonous plants.

Keller, T.

2010-12-01

The National Academy of Sciences has created a committee of 18 National Academy of Science and Engineering members, academic scientists, cognitive and learning scientists, and educators, educational policymakers and researchers to develop a framework to guide new K-12 science education standards. The committee began its work in January, 2010, released a draft of the framework in July, 2010, and intends to have the final framework in the first quarter of 2011. The committee was helped in early phases of the work by consultant design teams. The framework is designed to help realize a vision for science and engineering education in which all students actively engage in science and engineering practices in order to deepen their understanding of core ideas in science over multiple years of school. These three dimensions - core disciplinary ideas, science and engineering practices, and cross-cutting elements - must blend together to build an exciting, relevant, and forward looking science education. The framework will be used as a base for development of next generation K-12 science education standards.

Animal models which allow the temporal regulation of gene activities are valuable for dissecting gene function in tumorigenesis. Here we have constructed a conditional inducible estrogen receptor-K-ras(G12D) (ER-K-ras(G12D)) knock-in mice allele that allows us to temporally switch on or off the activity of K-ras oncogenic mutant through tamoxifen administration. In vitro studies using mice embryonic fibroblast (MEF) showed that a dose of tamoxifen at 0.05 µM works optimally for activation of ER-K-ras(G12D) independent of the gender status. Furthermore, tamoxifen-inducible activation of K-ras(G12D) promotes cell proliferation, anchor-independent growth, transformation as well as invasion, potentially via activation of downstream MAPK pathway and cell cycle progression. Continuous activation of K-ras(G12D) in vivo by tamoxifen treatment is sufficient to drive the neoplastic transformation of normal lung epithelial cells in mice. Tamoxifen withdrawal after the tumor formation results in apoptosis and tumor regression in mouse lungs. Taken together, these data have convincingly demonstrated that K-ras mutant is essential for neoplastic transformation and this animal model may provide an ideal platform for further detailed characterization of the role of K-ras oncogenic mutant during different stages of lung tumorigenesis.

Scientists and K-12: Experience from The Science House

NASA Astrophysics Data System (ADS)

Haase, David G.

2003-03-01

In working with K-12 science and mathematics education, scientists may take on many different roles - from presenter to full-time partner. These roles are illustrated in the activities of The Science House, a K-12 education program of North Carolina State University, (www.science-house.org) which partners with teachers and students across the state to promote inquiry-based learning in mathematics and science. While it is important to involve scientists in K-12, most universities do not have effective means to make the connections. In our efforts to do so, which began with a few teacher workshops and now encompasses six offices across NC, we have sought to join the interests of the university (research, teaching, student recruiting) to the needs of K-12. Our programs now include teacher training workshops, student science camps and curriculum projects in several states. We are reminded that K-12 science education is interdisciplinary; local and political; and a process, not a problem to be solved and forgotten.

For the aging populations of any nation, Dementia is becoming a primary problem and Alzheimer’s dementia (AD) is the most common type. However, until now, there is no effective treatment for AD. Tanshinone IIA (Tan IIA) has been reported for neuroprotective potential to against amyloid β peptides (Aβ)-induced cytotoxicity in the rat pheochromocytoma cell line PC-12, which is widely used as AD research model, but the mechanism still remains unclear. To investigate the effect of Tan IIA and the possible molecular mechanism in the apoptosis of PC12 cells, we induced apoptosis in PC12 cells with β-amyloid(25-35), and treated cells with Tan IIA. After 24 h treatment, we found that Tan IIA increased the cell viability and reduced the number of apoptotic cells induced by Aβ(25-35). However, neuroprotection of Tan IIA was abolished by PI3K inhibitor LY294002. Meanwhile, Treatment with lithium chloride, a phosphorylation inhibitor of GSK3β, which is a downstream target of PI3K/Akt, can block Aβ(25-35)-induced cell apoptosis in a Tan IIA-like manner. Our findings suggest that Tan IIA is an effective neuroprotective agent and a viable candidate in AD therapy and PI3K/Akt activation and GSK3β phosphorylation are involved in the neuroprotection of Tan IIA.

Nutrients in the Nation?s streams and groundwater: National Findings and Implications

USGS Publications Warehouse

Dubrovsky, Neil M.; Hamilton, Pixie A.

2010-01-01

A comprehensive national analysis of the distribution and trends of nutrient concentrations in streams and groundwater from 1992 through 2004 is provided by the National Water-Quality Assessment (NAWQA) Program of the United States Geological Survey (USGS). Findings describe the distribution and causes of varying nutrient concentrations in streams and groundwater throughout the Nation and examine the primary sources that contribute to elevated concentrations. Results show that excessive nutrient enrichment is a widespread cause of ecological degradation in streams and that nitrate contamination of groundwater used for drinking water, particularly shallow domestic wells in agricultural areas, is a continuing human-health concern. Finally, despite major Federal, State and local nonpoint-source nutrient control efforts for streams and watersheds across the Nation, USGS trend analyses for 1993?2003 suggest limited national progress to reduce the impacts of nonpoint sources of nutrients during this period. Instead, concentrations have remained the same or increased in many streams and aquifers across the Nation, and continue to pose risks to aquatic life and human health. This Fact Sheet highlights selected national findings and their implications, and serves as a companion product to the complete analysis reported in the USGS Circular titled ?The Quality of Our Nation?s Waters?Nutrients in the Nation?s Streams and Groundwater, 1992?2004.?

NSF GK-12 Fellows as Mentors for K-12 Teachers Participating in Field Research Experiences

Ellins, K.; Perry, E.

2005-12-01

The University of Texas Institute for Geophysics (UTIG) recognizes the value of providing educational opportunities to K-12 teachers who play a critical role in shaping the minds of young people who are the future of our science. To that end, UTIG established the "Texas Teachers in the Field" program in 2000 to formalize the participation of K-12 teachers in field programs that included UTIG scientists. In 2002, "Texas Teachers in the Field" evolved through UTIG's involvement in a University of Texas at Austin GK-12 project led by the Environmental Sciences Institute, which enabled UTIG to partner a subset of GK-12 Fellows with teachers participating in geophysical field programs. During the three years of the GK-12 project, UTIG successfully partnered four GK-12 Fellows with five K-12 teachers. The Fellows served as mentors to the teachers, as liaisons between UTIG scientists leading field programs and teachers and their students, and as resources in science, mathematics, and technology instruction. Specifically, Fellows prepared teachers and their students for the field investigations, supervised the design of individual Teacher Research Experience (TRE) projects, and helped teachers to develop standards-aligned curriculum resources related to the field program for use in their own classrooms, as well as broader distribution. Although all but one TRE occurred during the school year, Texas school districts and principals were willing to release teachers to participate because the experience and destinations were so extraordinary (i.e., a land-based program in Tierra del Fuego, Argentina; and research cruises to the Southeast Caribbean Sea and Hess Deep in the Pacific Ocean) and carried opportunities to work with scientists from around the world. This exceptional collaboration of GK-12 Fellows, K-12 teachers and research scientists enriches K-12 student learning and promotes greater enthusiasm for science.

Involving Practicing Scientists in K-12 Science Teacher Professional Development

NASA Astrophysics Data System (ADS)

Bertram, K. B.

2011-12-01

The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

2016-03-01

This study assessed students' attitudes toward science in Qatar. A cross-sectional, nationwide probability sample representing all students enrolled in grades 3 through 12 in the various types of schools in Qatar completed the 'Arabic Speaking Students' Attitudes toward Science Survey' (ASSASS). The validity and reliability of the 32-item instrument, encompassing five sub-scales, have already been shown to be robust. The present analysis focused on responses from 1978 participants representing the students who completed the ASSASS in Arabic. Descriptive statistics were computed and a competing pair of multiple indicators multiple causes models is presented that attempt to link patterns in students' responses to the ASSASS with a set of indicators. The final model retained student age, gender, nationality (i.e. Qatari vs. Non-Qatari Arab), and school type as indicators. Findings from this study suggest that participants' attitudes toward science decrease with age, and that these attitudes and related preferences are influenced by students' nationality and the type of school they attend. Equally important, the often-reported advantages for male over female precollege students in terms of attitudes toward science were much less prominent in the present study.

Discovery of a Kojibiose Phosphorylase in Escherichia coli K-12.

The substrate profiles for three uncharacterized enzymes (YcjM, YcjT, and YcjU) that are expressed from a cluster of 12 genes ( ycjM-W and ompG) of unknown function in Escherichia coli K-12 were determined. Through a comprehensive bioinformatic and steady-state kinetic analysis, the catalytic function of YcjT was determined to be kojibiose phosphorylase. In the presence of saturating phosphate and kojibiose (α-(1,2)-d-glucose-d-glucose), this enzyme catalyzes the formation of d-glucose and β-d-glucose-1-phosphate ( k cat = 1.1 s -1 , K m = 1.05 mM, and k cat / K m = 1.12 × 10 3 M -1 s -1 ). Additionally, it was also shown that in the presence of β-d-glucose-1-phosphate, YcjT can catalyze the formation of other disaccharides using 1,5-anhydro-d-glucitol, l-sorbose, d-sorbitol, or l-iditol as a substitute for d-glucose. Kojibiose is a component of cell wall lipoteichoic acids in Gram-positive bacteria and is of interest as a potential low-calorie sweetener and prebiotic. YcjU was determined to be a β-phosphoglucomutase that catalyzes the isomerization of β-d-glucose-1-phosphate ( k cat = 21 s -1 , K m = 18 μM, and k cat / K m = 1.1 × 10 6 M -1 s -1 ) to d-glucose-6-phosphate. YcjU was also shown to exhibit catalytic activity with β-d-allose-1-phosphate, β-d-mannose-1-phosphate, and β-d-galactose-1-phosphate. YcjM catalyzes the phosphorolysis of α-(1,2)-d-glucose-d-glycerate with a k cat = 2.1 s -1 , K m = 69 μM, and k cat / K m = 3.1 × 10 4 M -1 s -1 .

Gueye, Paul

2010-03-01

The National Society of Black Physicists, along with the National Society of Hispanic Physicists, has been reaching out to the minority K-12 population by revolutionizing its Science Ambassador program under its Pre-College Program Committee. Since 2005, both societies have been providing unique interactive physics demonstrations to predominantly minority schools to expose them to the exciting world of physics. In a four year span, the population of targeted students went from 25 (2005) to 400 (2009). During the 2009 joint annual meeting, a Physics Day camp was introduced during which eight physics societies combined their efforts to reach to a larger group of students in a short time period. This initiative has now tackled the unique feature to expand nationally by reaching out to the members of all physics societies. While the world of optics has been an integral part of the demonstrations being performed on stage or at individual booths, physics concepts and its applications in medical physics (such as imaging or therapy) is the focus of the 2010 effort as part of LaserFest. This talk will review the impact of this program in the minority community and the importance of physics department at minority institutions in changing the conception of science in K-12 arenas.

Finding the K best synthesis plans.

PubMed

Fagerberg, Rolf; Flamm, Christoph; Kianian, Rojin; Merkle, Daniel; Stadler, Peter F

2018-04-05

In synthesis planning, the goal is to synthesize a target molecule from available starting materials, possibly optimizing costs such as price or environmental impact of the process. Current algorithmic approaches to synthesis planning are usually based on selecting a bond set and finding a single good plan among those induced by it. We demonstrate that synthesis planning can be phrased as a combinatorial optimization problem on hypergraphs by modeling individual synthesis plans as directed hyperpaths embedded in a hypergraph of reactions (HoR) representing the chemistry of interest. As a consequence, a polynomial time algorithm to find the K shortest hyperpaths can be used to compute the K best synthesis plans for a given target molecule. Having K good plans to choose from has many benefits: it makes the synthesis planning process much more robust when in later stages adding further chemical detail, it allows one to combine several notions of cost, and it provides a way to deal with imprecise yield estimates. A bond set gives rise to a HoR in a natural way. However, our modeling is not restricted to bond set based approaches-any set of known reactions and starting materials can be used to define a HoR. We also discuss classical quality measures for synthesis plans, such as overall yield and convergency, and demonstrate that convergency has a built-in inconsistency which could render its use in synthesis planning questionable. Decalin is used as an illustrative example of the use and implications of our results.

12k, a taspine derivative, has been demonstrated to have the potent anti-tumor activity in lung cancer and colorectal cancer. The study aims to further explore the underlying mechanisms of 12k on A549 cell migration in vitro. Our data demonstrated that 12k negatively regulated Wnt signaling pathway by suppressing the phosphorylation of LRP5/6, and inhibiting the expression and nuclear translocation of β-catenin. 12k was shown to downregulate MMP3 and MMP7 expression which regulated by β-catenin interacts with TCF/LEF in the nucleus, and effectively impaired the related migration protein expression of MMP2 and MMP9 in A549 cells. In addition, 12k repressed the EphrinB2 and its PDZ protein, impairing the VEGFR2 and VEGFR3 expression in A549 cells, as well as inhibited the downstream of VEGFR2 included PI3K/AKT/mTOR and ERK/MAPK signaling pathways. Taken together, our findings revealed that 12k suppressed migration of A549 cells through the Wnt/β-catenin signaling pathway and EphrinB2 related signaling pathway.

The Next Generation Science Standards: An Historic Opportunity for K-12 Earth and Space Science Education

NASA Astrophysics Data System (ADS)

Johnson, R. M.; Passow, M. J.; Holzer, M. A.; Moore, J.

2014-12-01

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

Rapid changes in dietary patterns, economic development, and urbanization in low- to middle-income countries are fueling complex malnutrition states that need better characterization using population-level data. The aim of this study was to describe the key findings related to vitamin B12 status to identify the prevalence and associated sociodemographic factors in a representative sample of children in Colombia, based on the 2010 National Nutrition Survey. We analyzed cross-sectional data from 6910 Colombian children between the ages of 5 and 12. Serum vitamin B12 concentrations were determined by chemiluminescence. Sociodemographic data was assessed by computer-assisted personal interview technology. Of the children assessed, 2.8% had vitamin B12 deficiency, defined as levels <200 pg/mL, and 18.1% had marginal vitamin B12 deficiency, defined as levels between 200 and 300 pg/mL. A multivariate logistic regression analysis revealed increased risks for vitamin B12 deficiency among children ages ≥9 y and for those living in the eastern, western, and southern regions of the country. No significant associations were found for ethnic groups, socioeconomic status, or urbanity levels. Being 11 y of age (odds ratio [OR], 2.16; 95% confidence interval [CI], 1.56-3.00; P = 0.0001), living in the west (Pacific) region of the country (OR, 3.92; 95% CI, 3.14-4.90; P = 0.0001), and being male (OR, 1.41; 95% CI, 1.20-1.65; P = 0.0001) were the factors most strongly associated with an increased risk for vitamin B12 deficiency. Compared with data from other Latin American countries, Colombian children have a lower prevalence of vitamin B12 deficiency; however the prevalence of marginal deficiency is substantial. Continued surveillance and implementation of interventions to improve dietary patterns among the high-risk groups identified should be considered. Copyright © 2016 Elsevier Inc. All rights reserved.

2004-12-01

The study of climate and global change is an important on-going focus for scientists at the National Center for Atmospheric Research (NCAR). Programs overseen by the University Corporation for Atmospheric Research Office of Education and Outreach (UCAR-EO) help to translate NCAR's scientific programs, methodologies, and technologies and their societal benefits to over 80,000 visitors to the NCAR Mesa Laboratory each year, including about 10,000 K-12 students. This is currently accomplished through the implementation of an increasingly integrated system of exhibits, guided tours, an audiotour, programs for school groups, and a teachers' guide to the exhibits, which is currently in development. The Climate Discovery Exhibit unveiled in July 2003 and expanded in 2004 offers visitors visually engaging and informative text panels, graphics, artifacts, and interactives describing Sun-Earth connections, dynamic processes that contribute to and mediate climate change, and the Earth's climate history. The exhibit seeks to help visitors to understand why scientists model the global climate system and how information about past and current climate is used to validate models and build scenarios for Earth's future climate. Exhibit-viewers are challenged to ask questions and reflect upon decision making challenges while considering the roles various natural and human-induced factors play in shaping these predictions. With support from NASA and NCAR, a K-12 Teacher's Guide has been developed corresponding the Climate Discovery exhibit's sections addressing the Sun-Earth connection and past climates (the Little Ice Age, in particular). This presentation will review efforts to identify the challenges of communicating with the public and school groups about climate change, while also describing several successful strategies for utilizing visitor questionnaires and interviews to learn how to develop and refine educational resources that will target their interests, bolster their

2006-01-01

The goal of this group project has been to coordinate and bring up-to-date information on all genes of Escherichia coli K-12. Annotation of the genome of an organism entails identification of genes, the boundaries of genes in terms of precise start and end sites, and description of the gene products. Known and predicted functions were assigned to each gene product on the basis of experimental evidence or sequence analysis. Since both kinds of evidence are constantly expanding, no annotation is complete at any moment in time. This is a snapshot analysis based on the most recent genome sequences of two E.coli K-12 bacteria. An accurate and up-to-date description of E.coli K-12 genes is of particular importance to the scientific community because experimentally determined properties of its gene products provide fundamental information for annotation of innumerable genes of other organisms. Availability of the complete genome sequence of two K-12 strains allows comparison of their genotypes and mutant status of alleles. PMID:16397293

Valine inhibition of the growth of Escherichia coli strain K-12. J. Bacteriol. 83:624–630. 1962.—The inhibition of the growth of Escherichia coli strain K-12 by valine was shown to be due to the sensitivity of the acetohydroxybutyrate-forming system to valine. It was demonstrated that both E. coli strain W, a strain whose growth is unaffected by valine, and a valine-resistant mutant of strain K-12 have acetolactate- and acetohydroxybutyrate-forming systems which are less sensitive to valine than that of strain K-12. It was further shown that α-aminobutyrate accumulates in the culture fluid of the valine-sensitive strain when incubated in the presence of valine. The levels of valine in the “free amino acid pool” were examined and found to be related to the differences in valine sensitivity of the acetolactate-forming systems of the three strains.

1998-05-01

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.

The local crystallographic structure at room temperature (RT) does not change by adding K 0.5Na 0.5NbO 3 to Bi 1/2Na 1/2TiO 3-xBi 1/2K 1/2TiO 3 for x = 0.2 and 0.4. The average crystal structure and microstructure on the other hand develop from mainly long-range polar order with ferroelectric domains to short-range order with polar nanoregions displaying amore » more pronounced relaxor character. The (0.1; 0) and (0.1; 0.02) compositions exhibit monoclinic Cc space group symmetry, which transform into Cc + P4bm at 185 and 130 °C, respectively. This high temperature phase is stable at RT for the morphotropic phase boundary compositions of (0.1; 0.05) and all compositions with x = 0.2. For the compositions of (0.1; 0) and (0.1; 0.02), local structural changes on heating are evidenced by Raman; for all other compositions, changes in the long-range average crystal structure were observed.« less

A phenomenological case study concerning science teacher educators' beliefs and teaching practices about culturally relevant pedagogy and preparing K-12 science teachers to engage African American students in K-12 science

NASA Astrophysics Data System (ADS)

Underwood, Janice Bell

Due to the rising diversity in today's schools, science teacher educators (STEs) suggest that K-12 teachers must be uniquely prepared to engage these students in science classrooms. Yet, in light of the increasing white-black science achievement gap, it is unclear how STEs prepare preservice teachers to engage diverse students, and African Americans in particular. Therefore, the purpose of this study was to find out how STEs prepare preservice teachers to engage African American students in K-12 science. Thus, using the culturally relevant pedagogy (CRP) framework, this phenomenological case study explored beliefs about culturally relevant science teaching and the influence of reported beliefs and experiences related to race on STEs' teaching practices. In the first phase, STE's in a mid-Atlantic state were invited to participate in an electronic survey. In the second phase, four participants, who were identified as exemplars, were selected from the survey to participate in three semi-structured interviews. The data revealed that STEs were more familiar with culturally responsive pedagogy (CResP) in the context of their post-secondary classrooms as opposed to CRP. Further, most of the participants in part one and two described modeling conventional ways they prepare their preservice teachers to engage K-12 students, who represent all types of diversity, without singling out any specific race. Lastly, many of the STEs' in this study reported formative experiences related to race and beliefs in various manifestations of racism have impacted their teaching beliefs and practices. The findings of this study suggest STEs do not have a genuine understanding of the differences between CRP and CResP and by in large embrace CResP principles. Secondly, in regards to preparing preservice teachers to engage African American students in science, the participants in this study seemed to articulate the need for ideological change, but were unable to demonstrate pedagogical changes

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.

Mentoring is critical for academic success. As science transitions to a team science model, team mentoring may have advantages. The goal of this study was to understand the process, benefits, and challenges of team mentoring relating to career development and research. A national survey was conducted of Building Interdisciplinary Research Careers in Women's Health (BIRCWH) program directors-current and former scholars from 27 active National Institutes of Health (NIH)-funded BIRCWH NIH K12 programs-to characterize and understand the value and challenges of the team approach to mentoring. Quantitative data were analyzed descriptively, and qualitative data were analyzed thematically. Responses were received from 25/27 (93%) program directors, 78/108 (72%) current scholars, and 91/162 (56%) former scholars. Scholars reported that team mentoring was beneficial to their career development (152/169; 90%) and research (148/169; 88%). Reported advantages included a diversity of opinions, expanded networking, development of stronger study designs, and modeling of different career paths. Challenges included scheduling and managing conflicting opinions. Advice by directors offered to junior faculty entering team mentoring included the following: not to be intimidated by senior mentors, be willing to navigate conflicting advice, be proactive about scheduling and guiding discussions, have an open mind to different approaches, be explicit about expectations and mentors' roles (including importance of having a primary mentor to help navigate discussions), and meet in person as a team. These findings suggest that interdisciplinary/interprofessional team mentoring has many important advantages, but that skills are required to optimally utilize multiple perspectives.

2015-03-01

The National Science Foundation and other funding agencies are increasingly requiring broader impacts in grant applications to encourage US scientists to contribute to science education and society. Concurrently, national science education standards are using more inquiry-based learning (IBL) to increase students' capacity for abstract, conceptual thinking applicable to real-world problems. Scientists are particularly well suited to engage in broader impacts via science inquiry outreach, because scientific research is inherently an inquiry-based process. We provide a practical guide to help scientists overcome obstacles that inhibit their engagement in K-12 IBL outreach and to attain the accrued benefits. Strategies to overcome these challenges include scaling outreach projects to the time available, building collaborations in which scientists' research overlaps with curriculum, employing backward planning to target specific learning objectives, encouraging scientists to share their passion, as well as their expertise with students, and transforming institutional incentives to support scientists engaging in educational outreach.

Involvement of IGF-1 and MEOX2 in PI3K/Akt1/2 and ERK1/2 pathways mediated proliferation and differentiation of perivascular adipocytes

DOE Office of Scientific and Technical Information (OSTI.GOV)

Liu, Ping, E-mail: lping@sdu.edu.cn; Kong, Feng; Wang, Jue

Perivascular adipocyte (PVAC) proliferation and differentiation were closely involved in cardiovascular disease. We aimed to investigate whether phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling pathways enhance PVAC functions activated by insulin-like growth factor 1(IGF-1) and suppressed by mesenchyme homeobox 2 (MEOX2). In this study, PVACs from primary culture were cultured and induced to differentiate. Cell viability assays demonstrated that IGF-1 promoted PVAC proliferation and differentiation. However MEOX2 counteracted these IGF-1-mediated actions. Flow Cytometry revealed that IGF-1 increased S phase cells and decreased apoptosis; however, MEOX2 decreased S phase cells, increased G0–G1 phase cells, and promoted apoptosis. During PVACmore » proliferation and differentiation, IGF-1 activated PI3K/Akt1/2 and ERK1/2 signaling pathways, upregulated the expression of these signaling proteins and FAS, and increased PVAC lipid content. In contrast, MEOX2 constrained the phosphorylation of ERK1/2 and Akt1/2 protein, down-regulated these signaling molecules and FAS, and decreased PVAC lipid content. Instead, MEOX2 knockdown enhanced the ERK1/2 and Akt1/2 phosphorylation, augmented the expression of these signaling molecules and FAS, and increased PVAC lipid content. Our findings suggested that PI3K/Akt1/2 and ERK1/2 activation mediated by IGF-1 is essential for PVAC proliferation and differentiation, and MEOX2 is a promising therapeutic gene to intervene in the signaling pathways and inhibit PVAC functions. - Highlights: • IGF-1 activated PI3K/Akt2 and ERK1/2 pathways to mediate PVAC proliferation and differentiation. • The expression of ERK1, ERK 2, PI3K, Akt1 and Akt2 showed different change trends between PVAC proliferation and differentiation. • MEOX2 effectively expressed in PVAC, increased early and late cellular apoptosis, and inhibited its proliferation. • MEOX2 depressed PVAC differentiation and FAS

Development of an Attitude Scale to Assess K-12 Teachers' Attitudes toward Nanotechnology

NASA Astrophysics Data System (ADS)

Lan, Yu-Ling

2012-05-01

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.

Outsider to insider: resetting the natural host niche of commensal E. coli K-12.

PubMed

Sahu, Upasana; Kar, Sudeshna

2012-01-01

The status of E. coli K-12 as an exclusively non-invasive, non-pathogenic bacterium has almost been incontrovertible. Our recent finding that a mutation in one of its main architectural protein, HU, converts E. coli K-12 to an actively invasive form suggests that gaining host cell entry might be an expedient survival tactic for traditional commensals during certain altered host conditions. The mutant E. coli (SK3842) exhibits properties usually associated with pathogenic bacteria: host cell invasion, phagosomal disruption and intracellular replication. However, unlike the situation with some pathogens, internalized SK3842 imparts anti-apoptotic and cyto-protective effects rather than lethality on the host cell, both in vitro and in vivo. Here, we show that SK3842 also provides colonization resistance against other invasive pathogens--a trait not shared by the parental commensal strain. Thus, the altered lifestyle of SK3842 encompasses characteristics both from traditional pathogens as well as beneficial probiotic strains.

K-12 educators need effective and relevant astronomy professional development. NASA's Mission Science provides innovative and accessible opportunities for K-12 teachers. Science questions involve scale and distance, including Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers can gain an understanding of basic telescopes, the history of telescopes, ground and satellite based telescopes, and models of JWST Telescope. An in-depth explanation of JWST and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. During teacher training, 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 lenticulars and diagramming of infrared data, 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 Washington STEM, NASA, and the Washington Space Grant Consortium.

Comparison of the large-scale periplasmic proteomes of the Escherichia coli K-12 and B strains.

PubMed

Han, Mee-Jung; Kim, Jin Young; Kim, Jung A

2014-04-01

Escherichia coli typically secretes many proteins into the periplasmic space, and the periplasmic proteins have been used for the secretory production of various proteins by the biotechnology industry. However, the identity of all of the E. coli periplasmic proteins remains unknown. Here, high-resolution periplasmic proteome reference maps of the E. coli K-12 and B strains were constructed and compared. Of the 145 proteins identified by tandem mass spectrometry, 61 proteins were conserved in the two strains, whereas 11 and 12 strain-specific proteins were identified for the E. coli K-12 and B strains, respectively. In addition, 27 proteins exhibited differences in intensities greater than 2-fold between the K-12 and B strains. The periplasmic proteins MalE and OppA were the most abundant proteins in the two E. coli strains. Distinctive differences between the two strains included several proteins that were caused by genetic variations, such as CybC, FliC, FliY, KpsD, MglB, ModA, and Ybl119, hydrolytic enzymes, particularly phosphatases, glycosylases, and proteases, and many uncharacterized proteins. Compared to previous studies, the localization of many proteins, including 30 proteins for the K-12 strain and 53 proteins for the B strain, was newly identified as periplasmic. This study identifies the largest number of proteins in the E. coli periplasm as well as the dynamics of these proteins. Additionally, these findings are summarized as reference proteome maps that will be useful for studying protein secretion and may provide new strategies for the enhanced secretory production of recombinant proteins.

The influence of excess K2O on the electrical properties of (K,Na)1/2Bi1/2TiO3 ceramics

NASA Astrophysics Data System (ADS)

Li, Linhao; Li, Ming; Sinclair, Derek C.

2018-04-01

The solid solution (KxNa0.50-x)Bi0.50TiO3 (KNBT) between Na1/2Bi1/2TiO3 and K1/2Bi1/2TiO3 (KBT) has been extensively researched as a candidate lead-free piezoelectric material because of its relatively high Curie temperature and good piezoelectric properties, especially near the morphotropic phase boundary (MPB) at x ˜ 0.10 (20 mol. % KBT). Here, we show that low levels of excess K2O in the starting compositions, i.e., (Ky+0.03Na0.50-y)Bi0.50TiO3.015 (y-series), can significantly change the conduction mechanism and electrical properties compared to a nominally stoichiometric KNBT series (KxNa0.50-x)Bi0.50TiO3 (x-series). Impedance spectroscopy measurements reveal significantly higher bulk conductivity (σb) values for y ≥ 0.10 samples [activation energy (Ea) ≤ 0.95 eV] compared to the corresponding x-series samples which possess bandgap type electronic conduction (Ea ˜ 1.26-1.85 eV). The largest difference in electrical properties occurs close to the MPB composition (20 mol. % KBT) where y = 0.10 ceramics possess σb (at 300 °C) that is 4 orders of magnitude higher than that of x = 0.10 and the oxide-ion transport number in the former is ˜0.70-0.75 compared to <0.05 in the latter (between 600 and 800 °C). The effect of excess K2O can be rationalised on the basis of the (K + Na):Bi ratio in the starting composition prior to ceramic processing. This demonstrates the electrical properties of KNBT to be sensitive to low levels of A-site nonstoichiometry and indicates that excess K2O in KNBT starting compositions to compensate for volatilisation can lead to undesirable high dielectric loss and leakage currents at elevated temperatures.

Technical Feasibility Study for Zero Energy K-12 Schools

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pless, Shanti D.; Torcellini, Paul A.; Bonnema, Eric

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 requiredmore » 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.« less

Structure and Differentiated Electrical Characteristics of M1/2La1/2Cu3Ti4O12 (M = Li, Na, K) Ceramics Prepared by Sol-Gel Method

NASA Astrophysics Data System (ADS)

Liu, Zhanqing; Yang, Zupei

2017-10-01

New M1/2La1/2Cu3Ti4O12 (M = Li, Na, K) ceramics based on partial substitution of Li+, Na+, and K+ for La3+ in La2/3Cu3Ti4O12 (LCTO) have been prepared by a sol-gel method, and the effects of Li+, Na+, and K+ on the microstructure and electrical properties investigated in detail, revealing different results depending on the substituent. The cell parameter increased with increasing radius of the substituent ion (Li+, Na+, K+). Li1/2La1/2Cu3Ti4O12 (LLCTO) ceramic showed better frequency and temperature stability, but the dielectric constant decreased and the third abnormal dielectric peak disappeared from the dielectric temperature spectrum. Na1/2La1/2Cu3Ti4O12 (NLCTO) ceramic exhibited higher dielectric constant and better frequency and temperature stability, and displayed the second dielectric relaxation in electric modulus plots. The performance of K1/2La1/2Cu3Ti4O12 (KLCTO) ceramic was deteriorated. These different microstructures and electrical properties may be due to the effect of different defect structures generated in the ceramic as well as grain size. This work represents the first analysis and comparison of these remarkable differences in the electrical behavior of ceramics obtained by partial substitution of Li+, Na+, and K+ for La3+ in LCTO.

K{sub 3}InF{sub 6} is synthesized by a sol-gel route starting from indium and potassium acetates dissolved in isopropanol in the stoichiometry 1:3, with trifluoroacetic acid as fluorinating agent. The crystal structures of the organic precursors were solved by X-ray diffraction methods on single crystals. Three organic compounds were isolated and identified: K{sub 2}InC{sub 10}O{sub 10}H{sub 6}F{sub 9}, K{sub 3}InC{sub 12}O{sub 14}H{sub 4}F{sub 18} and K{sub 3}InC{sub 12}O{sub 12}F{sub 18}. The first one, deficient in potassium in comparison with the initial stoichiometry, is unstable. In its crystal structure, acetate as well as trifluoroacetate anions are coordinated to the indium atom. Themore » two other precursors are obtained, respectively, by quick and slow evaporation of the solution. They correspond to the final organic compounds, which give K{sub 3}InF{sub 6} by decomposition at high temperature. The crystal structure of K{sub 3}InC{sub 12}O{sub 14}H{sub 4}F{sub 18} is characterized by complex anions [In(CF{sub 3}COO){sub 4}(OH{sub x}){sub 2}]{sup (5-2x)-} and isolated [CF{sub 3}COOH{sub 2-x}]{sup (x-1)-} molecules with x=2 or 1, surrounded by K{sup +} cations. The crystal structure of K{sub 3}InC{sub 12}O{sub 12}F{sub 18} is only constituted by complex anions [In(CF{sub 3}COO){sub 6}]{sup 3-} and K{sup +} cations. For all these compounds, potassium cations ensure only the electroneutrality of the structure. IR spectra of K{sub 2}InC{sub 10}O{sub 10}H{sub 6}F{sub 9} and K{sub 3}InC{sub 12}O{sub 12}F{sub 18} were also performed at room temperature on pulverized crystals.« less

Educating K-12 Students about Glacier Dynamics in a Changing Climate

NASA Astrophysics Data System (ADS)

Stearns, L. A.; Hamilton, G. S.

2005-12-01

Public awareness of climate change is growing in the United States. Popular movies, books and magazines are frequently addressing the issue of global warming - some with careful scientific research, but many with unrealistic statements. Early education about the basic principles and processes of climate change is necessary for the general public to distinguish fact from fiction. The U.S. National Science Foundation's GK-12 program (GK-12; grades K to 12) currently in its sixth year, provides an opportunity for scientific enrichment for students and their teachers at the K-12 level through collaborative pairings with science and engineering graduate students (the Fellows). The NSF GK-12 program at the University of Maine has three goals: to enrich the scientific education of the students by providing role models, expertise, and equipment that may not be accessible otherwise; to provide professional development for the teachers through curriculum enrichment and participation at science conferences; and to improve the teaching and communication skills of the Fellows. The University of Maine is one of over 100 U. S. universities participating in this program. During the 2004-05 academic year, 11 graduate and one undergraduate student Fellows, advised by University faculty members, taught at schools across the state of Maine. Fellows from, biology, earth science, ecology, engineering, food science, forestry, and marine science, and taught in their area of expertise. We created a hands-on activity for middle and high school students that describes glacier mass balance in a changing climate. The students make a glacier using glue, water and detergent ('flubber') and construct a glacier valley using plastic sheeting. Flubber behaves in mechanically similar ways to glacier ice, undergoing plastic deformation at low stresses and exhibiting brittle failure at high stresses. Students are encouraged to run several tests with different values for valley slope, glacier mass

2015-02-01

Perivascular adipocyte (PVAC) proliferation and differentiation were closely involved in cardiovascular disease. We aimed to investigate whether phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling pathways enhance PVAC functions activated by insulin-like growth factor 1(IGF-1) and suppressed by mesenchyme homeobox 2 (MEOX2). In this study, PVACs from primary culture were cultured and induced to differentiate. Cell viability assays demonstrated that IGF-1 promoted PVAC proliferation and differentiation. However MEOX2 counteracted these IGF-1-mediated actions. Flow Cytometry revealed that IGF-1 increased S phase cells and decreased apoptosis; however, MEOX2 decreased S phase cells, increased G0-G1 phase cells, and promoted apoptosis. During PVAC proliferation and differentiation, IGF-1 activated PI3K/Akt1/2 and ERK1/2 signaling pathways, upregulated the expression of these signaling proteins and FAS, and increased PVAC lipid content. In contrast, MEOX2 constrained the phosphorylation of ERK1/2 and Akt1/2 protein, down-regulated these signaling molecules and FAS, and decreased PVAC lipid content. Instead, MEOX2 knockdown enhanced the ERK1/2 and Akt1/2 phosphorylation, augmented the expression of these signaling molecules and FAS, and increased PVAC lipid content. Our findings suggested that PI3K/Akt1/2 and ERK1/2 activation mediated by IGF-1 is essential for PVAC proliferation and differentiation, and MEOX2 is a promising therapeutic gene to intervene in the signaling pathways and inhibit PVAC functions.

An analysis of United States K-12 stem education versus STEM workforce at the dawn of the digital revolution

NASA Astrophysics Data System (ADS)

Cataldo, Franca

The world is at the dawn of a third industrial revolution, the digital revolution, that brings great changes the world over. Today, computing devices, the Internet, and the World Wide Web are vital technology tools that affect every aspect of everyday life and success. While computing technologies offer enormous benefits, there are equally enormous safety and security risks that have been growing exponentially since they became widely available to the public in 1994. Cybercriminals are increasingly implementing sophisticated and serious hack attacks and breaches upon our nation's government, financial institutions, organizations, communities, and private citizens. There is a great need for computer scientists to carry America's innovation and economic growth forward and for cybersecurity professionals to keep our nation safe from criminal hacking. In this digital age, computer science and cybersecurity are essential foundational ingredients of technological innovation, economic growth, and cybersecurity that span all industries. Yet, America's K-12 education institutions are not teaching the computer science and cybersecurity skills required to produce a technologically-savvy 21st century workforce. Education is the key to preparing students to enter the workforce and, therefore, American K-12 STEM education must be reformed to accommodate the teachings required in the digital age. Keywords: Cybersecurity Education, Cybersecurity Education Initiatives, Computer Science Education, Computer Science Education Initiatives, 21 st Century K-12 STEM Education Reform, 21st Century Digital Literacies, High-Tech Innovative Problem-Solving Skills, 21st Century Digital Workforce, Standardized Testing, Foreign Language and Culture Studies, Utica College, Professor Chris Riddell.

A meta-analysis of self-monitoring on reading performance of K-12 students.

PubMed

Guzman, Guadalupe; Goldberg, Taryn S; Swanson, H Lee

2018-03-01

The published single-case design (SCD) research (N = 19 articles) on self-monitoring and reading performance was synthesized. The following inclusion criteria were used: (a) the study must have been peer-reviewed, (b) implemented an intervention targeting student self-monitoring of reading skills, (c) included data on at least 1 reading outcome, (d) included visual representation of the data, and (f) the study must have used an SCD to assess the topic of interest. A total of 67 participants, 45 males and 22 females, ranging in age from 7:8 -18:7 were included in the current meta-analysis. Ethnicity was reported for 42 students: 23 were Caucasian, 12 were African American, and 7 were Latino/Hispanic. Studies were compared with those meeting What Works Clearinghouse (WWC) standards and those not meeting standards. The Tau-U effect size (ES) method was the main calculation method used; however, Phi ES estimates are included for comparison purposes. Results indicated that self-monitoring had an overall significant large positive effect on the reading performance of K-12 students, Tau-U = 0.79, 95% confidence interval (CI) [0.64, 0.93], p < .0001. However, self-monitoring for studies that met WWC criteria yielded a larger overall positive ES, Tau-U = 0.93, 95% CI [0.79, 1.07], p < .0001. Although the current meta-analysis is limited to peer-reviewed SCD studies, the findings provide support for self-monitoring as an evidence-based reading intervention for students in Grades K-12. Furthermore, findings indicate that larger ES values were identified when consolidating studies based on WWC guidelines as compared with consolidating across all studies.

2012-04-01

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.

K-Ras Populates Conformational States Differently from Its Isoform H-Ras and Oncogenic Mutant K-RasG12D.

Parker, Jillian A; Volmar, Alicia Y; Pavlopoulos, Spiro; Mattos, Carla

2018-06-05

Structures of wild-type K-Ras from crystals obtained in the presence of guanosine triphosphate (GTP) or its analogs have remained elusive. Of the K-Ras mutants, only K-RasG12D and K-RasQ61H are available in the PDB representing the activated form of the GTPase not in complex with other proteins. We present the crystal structure of wild-type K-Ras bound to the GTP analog GppCH 2 p, with K-Ras in the state 1 conformation. Signatures of conformational states obtained by one-dimensional proton NMR confirm that K-Ras has a more substantial population of state 1 in solution than H-Ras, which predominantly favors state 2. The oncogenic mutant K-RasG12D favors state 2, changing the balance of conformational states in favor of interactions with effector proteins. Differences in the population of conformational states between K-Ras and H-Ras, as well as between K-Ras and its mutants, can provide a structural basis for focused targeting of the K-Ras isoform in cancer-specific strategies.

Collaborations between K-12 schools and universities for the purpose of improving science education are growing in number, but many question their effectiveness. After many years of outreach to local teachers, schools and districts, we have developed a collaboration that more effectively addresses school district goals and needs while providing university faculty and graduate students with real opportunities to contribute to science education in the schools. Funded by the NSF GK-12 program, we are working directly with school district curriculum specialists and classroom teachers to implement inquiry-based science investigations. Projects range from developing long-term research projects in middle and high school classrooms to assisting K-6 teachers in using kit-based science curriculum. As part of our program, we have gathered several types of data to document the impact of our efforts. Using surveys of knowledge and attitudes, we measured significant improvements in college student's knowledge and attitudes about inquiry teaching methods and the K-12 education system. Through analysis of the college student's journals, we have also documented critical elements of an effective collaboration. These journals, combined with evaluations by classroom teachers, provide evidence of how the program impacts the graduate students professionally. We have also surveyed classroom teachers to measure the impact of the college students on their attitudes about teaching science and the long-term impact of the collaboration on their classroom teaching.

Listening to the soloists in the choir: A study of the life experience of exemplary K--12 environmental educators

NASA Astrophysics Data System (ADS)

Carter, Robert L.

Following the environmental awakening of the last third of the twentieth century, anchored by the enactment of the National Environmental Policy Act of 1969, education, and its frontline providers---teachers---were expected to become the dominant engines for realizing the new ideal of an environmentally literate populace. In reality, no such change has yet occurred despite continuous efforts from a variety of governmental and nongovernmental entities. A review of the literature revealed that there was something missing in research on the preparation of teachers for environmental education. There did not appear to be any research into why teachers who embrace the idea of environmental education as a fundamental part of education do so in the first place. In this study, described as basic qualitative research, I used a multiple-session interview technique to explore, in depth, the life experiences of the phenomenon I refer to as "an exemplary K-12 environmental educator." The pool of potential participants was composed of environmental education award winners from several states in the upper Midwest. Ten teachers were recruited from the available pool. Among these 10 were represented both genders, teaching in grades ranging from grade 2 through grade 12. The results of this study provide a look into a complex set of interactions which were eventually manifested as the phenomenon of interest. Highlights of the findings indicate that (1) a strong connection to the environment was developed early in life, (2) this connection was the result of experiences shared in the outdoors with significant others, (3) a love of learning and self-directedness are both integral to who these individuals are, (4) the study participants, as K-12 educators, draw heavily from the support of relevant professional associations. Implications for the continuing professional education of teachers in environmental education are that more emphasis is needed on awareness and affect as components

K-Ras(G12D)-selective inhibitory peptides generated by random peptide T7 phage display technology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sakamoto, Kotaro; Kamada, Yusuke; Sameshima, Tomoya

Amino-acid mutations of Gly{sup 12} (e.g. G12D, G12V, G12C) of V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (K-Ras), the most promising drug target in cancer therapy, are major growth drivers in various cancers. Although over 30 years have passed since the discovery of these mutations in most cancer patients, effective mutated K-Ras inhibitors have not been marketed. Here, we report novel and selective inhibitory peptides to K-Ras(G12D). We screened random peptide libraries displayed on T7 phage against purified recombinant K-Ras(G12D), with thorough subtraction of phages bound to wild-type K-Ras, and obtained KRpep-2 (Ac-RRCPLYISYDPVCRR-NH{sub 2}) as a consensus sequence. KRpep-2 showedmore » more than 10-fold binding- and inhibition-selectivity to K-Ras(G12D), both in SPR analysis and GDP/GTP exchange enzyme assay. K{sub D} and IC{sub 50} values were 51 and 8.9 nM, respectively. After subsequent sequence optimization, we successfully generated KRpep-2d (Ac-RRRRCPLYISYDPVCRRRR-NH{sub 2}) that inhibited enzyme activity of K-Ras(G12D) with IC{sub 50} = 1.6 nM and significantly suppressed ERK-phosphorylation, downstream of K-Ras(G12D), along with A427 cancer cell proliferation at 30 μM peptide concentration. To our knowledge, this is the first report of a K-Ras(G12D)-selective inhibitor, contributing to the development and study of K-Ras(G12D)-targeting drugs. - Highlights: • The first K-Ras(G12D)-selective inhibitory peptides were generated. • These peptides showed more than 10-fold binding- and inhibition-selectivity to K-Ras(G12D) in compared to wild type K-Ras. • The peptide KRpep-2d suppressed downstream signal of K-Ras(G12D) and cell proliferations of cancer cell line A427.« less

Demonstration of a 13 keV Kr K-shell X-Ray Source at the National Ignition Facility

NASA Astrophysics Data System (ADS)

Fournier, K. B.; May, M. J.; Colvin, J. D.; Barrios, M. A.; Patterson, J. R.; Regan, S. P.

2013-10-01

We report 3% conversion efficiency of laser energy into Kr K-shell (~13 keV) radiation, consistent with theoretical predictions. This is ~10 × greater than previous work. The emission was produced from a 4.1 mm diameter, 4 mm tall gas pipe target filled with 1.2 or 1.5 atm of Kr gas. 160 of the NIF laser beams deposited ~700 kJ of 3 ω light into the target in a ~140 TW, 5.0 ns duration square pulse. This laser configuration sufficiently heated the targets to optimize the K-shell x-ray emission. The Dante diagnostics measured ~5 TW into 4 π solid angle of >=12 keV x rays for ~4 ns, which includes both continuum emission and flux in the Kr Heα line at 13 keV. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. This work was supported by the Defense Threat Reduction Agency under the intera- gency agreements 10027-1420 and 10027-6167.

Engineering design skills coverage in K-12 engineering program curriculum materials in the USA

NASA Astrophysics Data System (ADS)

Chabalengula, Vivien M.; Mumba, Frackson

2017-11-01

The current K-12 Science Education framework and Next Generation Science Standards (NGSS) in the United States emphasise the integration of engineering design in science instruction to promote scientific literacy and engineering design skills among students. As such, many engineering education programmes have developed curriculum materials that are being used in K-12 settings. However, little is known about the nature and extent to which engineering design skills outlined in NGSS are addressed in these K-12 engineering education programme curriculum materials. We analysed nine K-12 engineering education programmes for the nature and extent of engineering design skills coverage. Results show that developing possible solutions and actual designing of prototypes were the highly covered engineering design skills; specification of clear goals, criteria, and constraints received medium coverage; defining and identifying an engineering problem; optimising the design solution; and demonstrating how a prototype works, and making iterations to improve designs were lowly covered. These trends were similar across grade levels and across discipline-specific curriculum materials. These results have implications on engineering design-integrated science teaching and learning in K-12 settings.

Finding reproducible cluster partitions for the k-means algorithm

PubMed Central

2013-01-01

K-means clustering is widely used for exploratory data analysis. While its dependence on initialisation is well-known, it is common practice to assume that the partition with lowest sum-of-squares (SSQ) total i.e. within cluster variance, is both reproducible under repeated initialisations and also the closest that k-means can provide to true structure, when applied to synthetic data. We show that this is generally the case for small numbers of clusters, but for values of k that are still of theoretical and practical interest, similar values of SSQ can correspond to markedly different cluster partitions. This paper extends stability measures previously presented in the context of finding optimal values of cluster number, into a component of a 2-d map of the local minima found by the k-means algorithm, from which not only can values of k be identified for further analysis but, more importantly, it is made clear whether the best SSQ is a suitable solution or whether obtaining a consistently good partition requires further application of the stability index. The proposed method is illustrated by application to five synthetic datasets replicating a real world breast cancer dataset with varying data density, and a large bioinformatics dataset.

Novel taspine derivative 12k inhibits cell growth and induces apoptosis in lung cell carcinoma.

PubMed

Dai, Bingling; Wang, Wenjie; Liu, Rui; Wang, Hongying; Zhang, Yanmin

2015-03-01

Taspine is an active compound in anticancer agent development. 12k was synthesized with taspine as lead compound bearing biphenyl scaffold and showed potent anticancer activity. Here, we investigated the effect of taspine derivative 12k on A549 lung cells. We showed that 12k not only decreased significantly A549 cell viability, A549 cell colony formation but also impaired A549 cell migration. Moreover, 12k treatment blocked cell cycle progression by increasing cell number in S phase to 42.80% for 6 μmol/L vs. 28.86% for control while decreasing cell number in G1 phase. Accordingly, this was associated with an increase protein expression of cyclin E and a decrease protein expression of cyclin D1, cyclin B1 and its associated CDK1 (cdc2). Meanwhile, we found that 12k induced A549 cell apoptosis, which was closely associated with the effect of the Bcl-2 family. Increase of Bad, Bak and Bax expression levels, decrease of Bcl-2 and Mcl-1 expression levels were observed. SiRNA knockdown of c-myc in A549 cells significantly attenuated tumor inhibition effects of 12k. In conclusion, our results demonstrate that 12k has an inhibitory effect on growth of A549 cell by inducing cell cycle arrest and apoptosis. Copyright © 2015 Elsevier Masson SAS.

Career education attitudes and practices of K-12 science educators

NASA Astrophysics Data System (ADS)

Smith, Walter S.

A random sample of 400 K-12 science educators who were members of the National Science Teachers Association were surveyed regarding their attitude toward and practice of career education in their science teaching. These science teachers rejected a narrowly vocational view, favoring instead a conception of career education which included self-perception, values analysis, and vocational skills objectives. The science educators affirmed the importance of career education for a student's education, asserted career education ought to be taught in their existing science courses, and expressed a willingness to do so. Fewer than one-third of the science teachers, however, reported incorporating career education at least on a weekly basis in their science lessons. The major impediment to including more career education in science teaching was seen to be their lack of knowledge of methods and materials relevant to science career education, rather than objections from students, parents, or administrators; their unwillingness; or their evaluation of career education as unimportant. Thus, in order to improve this aspect of science teaching, science teachers need more concrete information about science career education applications.

Energy, Society, and Education, with Emphasis on Educational Technology Policy for K-12

NASA Astrophysics Data System (ADS)

Chedid, Loutfallah Georges

2005-03-01

This paper begins by examining the profound impact of energy usage on our lives, and on every major sector of the economy. Then, the anticipated US energy needs by the year 2025 are presented based on the Department of Energy's projections. The paper considers the much-touted National Energy Policy Report, and identifies a major flaw where the policy report neglects education as a contributor to solving future energy problems. The inextricable interaction between energy solutions and education is described, with emphasis on education policy as a potential vehicle for developing economically and commercially sustainable energy systems that have a minimal impact on the environment. With that said, an earnest argument is made as to the need to educate science, technology, engineering, and mathematics (STEM) proficient individuals for the energy technology development workforce, starting with the K-12 level. A framework for the aforementioned STEM education policies is presented that includes a sustained national awareness campaign, address the teacher's salary issues, and addresses teacher quality issues. Moreover, the framework suggests a John Dewey-style "learning-by-doing" shift in pedagogy. Finally, the framework presents specific changes to the current national standards that would be valuable to the 21st century student.

Amino-acid mutations of Gly 12 (e.g. G12D, G12V, G12C) of V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (K-Ras), the most promising drug target in cancer therapy, are major growth drivers in various cancers. Although over 30 years have passed since the discovery of these mutations in most cancer patients, effective mutated K-Ras inhibitors have not been marketed. Here, we report novel and selective inhibitory peptides to K-Ras(G12D). We screened random peptide libraries displayed on T7 phage against purified recombinant K-Ras(G12D), with thorough subtraction of phages bound to wild-type K-Ras, and obtained KRpep-2 (Ac-RRCPLYISYDPVCRR-NH 2 ) as a consensus sequence. KRpep-2 showed more than 10-fold binding- and inhibition-selectivity to K-Ras(G12D), both in SPR analysis and GDP/GTP exchange enzyme assay. K D and IC 50 values were 51 and 8.9 nM, respectively. After subsequent sequence optimization, we successfully generated KRpep-2d (Ac-RRRRCPLYISYDPVCRRRR-NH 2 ) that inhibited enzyme activity of K-Ras(G12D) with IC 50  = 1.6 nM and significantly suppressed ERK-phosphorylation, downstream of K-Ras(G12D), along with A427 cancer cell proliferation at 30 μM peptide concentration. To our knowledge, this is the first report of a K-Ras(G12D)-selective inhibitor, contributing to the development and study of K-Ras(G12D)-targeting drugs. Copyright © 2017 Elsevier Inc.

Westenberg, David J

2016-03-01

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.

Integrating local environmental research into K-12 science classrooms and the value of graduate student-educator partnerships

Ward, N. D.; Petrik-Finley, R.

2015-12-01

Collaboration between researchers and K-12 educators enables an invaluable exchange of teaching philosophies and educational tools. Programs that partner graduate students with K-12 educators serve the dual purpose of training future educators and providing K-12 students with unique opportunities and perspectives. The benefits of this type of partnership include providing students with enhanced educational experiences and positive student-mentor relationships, training STEM graduate students in effective teaching strategies, and providing teachers with a firsthand resource for scientific information and novel educational materials. Many high school students have had little exposure to science beyond the classroom. Frequent interactions with "real-life" scientists can help make science more approachable and is an effective strategy for promoting science as a career. Here I describe my experiences and several lessons designed as a NSK GK-12 fellow. For example, a month-long unit on biogeochemical principles was framed as a crime scene investigation of a fish kill event in Hood Canal, Washington, in which students were given additional pieces of evidence to solve the mystery as they satisfied checkpoints in their understanding of key concepts. The evidence pieces included scientific plots, maps, datasets, and laboratory exercises. A clear benefit of this investigation-style unit is that students were able to learn the material at their individual pace. This structure allowed for a streamlined integration of differentiated materials such as simplified background readings or visual learning aids for struggling students or more detailed news articles and primary literature for more advanced students. Although the NSF GK-12 program has been archived, educators and researchers should pursue new partnerships, leveraging local and state-level STEM outreach programs with the goal of increasing national exposure of the societal benefits of such synergistic activities.

Effects of paraquat on Escherichia coli: Differences between B and K-12 strains

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kitzler, J.W.; Minakami, H.; Fridovich, I.

1990-02-01

Escherichia coli B and K-12 are equally susceptible to the bacteriostatic effects of aerobic paraquat, but they differed strikingly when the lethality of paraquat was evaluated. E. coli B suffered an apparent loss of viability when briefly exposed to paraquat, whereas E. coli K-12 did not. This difference depended on the ability of the B-strain, but not the K-12 strain, to retain internalized paraquat; the B strain was killed on aerobic tryptic soy-yeast extract plates during the incubation which preceded the counting of colonies. This difference in retention of paraquat between strains was demonstrated by delayed loss of viability, bymore » growth inhibition, and by cyanide-resistant respiration after brief exposure to paraquat, washing, and testing in fresh medium. This difference was also shown by using ({sup 14}C)paraquat. This previously unrecognized difference between E. coli B and K-12 has been the cause of apparently contradictory reports and should lead to some reevaluation of the pertinent literature.« less

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

PubMed

Di Pierro, Francesco; Colombo, Maria; Zanvit, Alberto; Rottoli, Amilcare S

2016-01-01

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. 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. 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. 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. Moreover, the benefits to children may also

The authors report preliminary findings of a national survey on school violence in Israel. The national representative sample was stratified on school type--elementary, middle, and high schools--and ethnicity--Jewish and Arab students. A total of 15,916 students from 603 classes and 232 schools participated in the study, resulting in a 91 percent response rate. Findings revealed high rates of violence in all areas and among all age groups, but relatively higher rates of low-level violent behaviors and lower rates of more severe violent events. The authors report on age-related, gender, and cultural differences and discuss social workers' roles in shaping national policy and professional discourse on school violence.

Evaluation of beta-lactose, PVP K12 and PVP K90 as excipients to prepare piroxicam granules using two wet granulation techniques.

PubMed

Albertini, Beatrice; Cavallari, Cristina; Passerini, Nadia; González-Rodríguez, M L; Rodriguez, Lorenzo

2003-11-01

The present investigation aimed at evaluating the use of different excipients, beta-lactose and polyvinylpyrrolidone of two molecular weights (PVP K12 and PVP K90), in the production of improved release piroxicam granules, by wet granulation using both water and steam as granulation liquid. The formulations examined were: piroxicam (Px)/beta-lactose; Px/PVP K12 and Px/PVP K90, each one at a 1:9 weight ratio. The most significant difference between beta-lactose and PVP is that, using the first excipient, both steam and water granules were produced while, when PVP were employed, only steam granules were obtained. Image analysis revealed that beta-lactose steam granules had a larger surface area with respect to water granules, whereas lower values of this parameter were observed in PVP-s granules, confirming the Scanning Electron Microscopy micrographs and the fractal analysis results. As regards the enhancement of the dissolution profiles, the best result was obtained using beta-lactose steam granules followed by PVP K12 ones, even if the reactive dimension values indicated that during the dissolution process PVP K12 granules modified the surface more than beta-lactose granules. As regards PVP K90, this excipient was the one less influencing the granule morphology and the dissolution behaviour. Differential Scanning Calorimetry analysis suggested the partial amorphisation of the drug in the granules containing the three excipients. This result was then confirmed by X-ray powder diffraction analysis. Therefore, beta-lactose and PVP K12 could be proposed as useful excipients to enhance the dissolution rate of Px from granules prepared using the steam granulation technique.

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

Crystal Growth of the S =1/2 Antiferromagnet K2PbCu(NO2)6 Elpasolite

NASA Astrophysics Data System (ADS)

Dong, Lianyang; Besara, Tiglet; Siegrist, Theo

The elpasolite K2PbCu(NO2)6is known for its two structural transitions at 281 K and 273 K. Single crystals of K2PbCu(NO2)6 have been grown in aqueous solution, but the rapid nucleation rate and convective transport renders it difficult to obtain large high quality single crystals. We developed a gel method to grow K2PbCu(NO2)6 Elpasolite with sizes up to 5x5x5 mm3, suitable for neutron diffraction measurements. Susceptibility measurements clearly show that the Jahn-Teller distortions at 286K and 273K with associated orbital ordering produce a linear chain Heisenberg antiferromagnetic system. The intrachain interaction strength has been derived from a Bonner-Fisher analysis that yielded a value of 5.4K. This work was supported by the National Science Foundation, under award DMR-1534818. A portion of this work has been performed at the National High Magnetic Field Laboratory, which is supported by the National Science Foundation Cooperative Agreement.

AIAA Educator Academy: Enriching STEM Education for K-12 Students

NASA Astrophysics Data System (ADS)

Slagle, E.; Bering, E. A.; Longmier, B. W.; Henriquez, E.; Milnes, T.; Wiedorn, P.; Bacon, L.

2012-12-01

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

Zero Energy Schools: Designing for the Future: Zero Energy Ready K-12 Schools

Torcellini, Paul A

Designing, building, and operating zero energy ready K-12 schools provides benefits for districts, students, and teachers. Optimizing energy efficiency is important in any building, but it's particularly important in K-12 schools. Many U.S. school districts struggle for funding, and improving a school building's energy efficiency can free up operational funds that may then be available for educational and other purposes.

The Oligo-Acyl Lysyl Antimicrobial Peptide C12K-2β12 Exhibits a Dual Mechanism of Action and Demonstrates Strong In Vivo Efficacy against Helicobacter pylori

PubMed Central

Makobongo, Morris O.; Gancz, Hanan; Carpenter, Beth M.; McDaniel, Dennis P.

2012-01-01

Helicobacter pylori has developed antimicrobial resistance to virtually all current antibiotics. Thus, there is a pressing need to develop new anti-H. pylori therapies. We recently described a novel oligo-acyl-lysyl (OAK) antimicrobial peptidomimetic, C12K-2β12, that shows potent in vitro bactericidal activity against H. pylori. Herein, we define the mechanism of action and evaluate the in vivo efficacy of C12K-2β12 against H. pylori after experimental infection of Mongolian gerbils. We demonstrate using a 1-N-phenylnaphthylamine (fluorescent probe) uptake assay and electron microscopy that C12K-2β12 rapidly permeabilizes the bacterial membrane and creates pores that cause bacterial cell lysis. Furthermore, using nucleic acid binding assays, Western blots, and confocal microscopy, we show that C12K-2β12 can cross the bacterial membranes into the cytoplasm and tightly bind to bacterial DNA, RNA, and proteins, a property that may result in inhibition of enzymatic activities and macromolecule synthesis. To define the in vivo efficacy of C12K-2β12, H. pylori-infected gerbils were orogastrically treated with increasing doses and concentrations of C12K-2β12 1 day or 1 week postinfection. The efficacy of C12K-2β12 was strongest in animals that received the largest number of doses at the highest concentration, indicating dose-dependent activity of the peptide (P < 0.001 by analysis of variance [ANOVA]) regardless of the timing of the treatment with C12K-2β12. Overall, our results demonstrate a dual mode of action of C12K-2β12 against the H. pylori membrane and cytoplasmic components. Moreover, and consistent with the previously reported in vitro efficacy, C12K-2β12 shows significant in vivo efficacy against H. pylori when used as monotherapy. Therefore, OAK peptides may be a valuable resource for therapeutic treatment of H. pylori infection. PMID:22064541

A bronze matryoshka: the discrete intermetalloid cluster [Sn@Cu12@Sn20](12-) in the ternary phases A12Cu12Sn21 (A = Na, K).

PubMed

Stegmaier, Saskia; Fässler, Thomas F

2011-12-14

The synthesis and crystal structure of the first ternary A-Cu-Sn intermetallic phases for the heavier alkali metals A = Na to Cs is reported. The title compounds A(12)Cu(12)Sn(21) show discrete 33-atom intermetalloid Cu-Sn clusters {Sn@Cu(12)@Sn(20)}, which are composed of {Sn(20)} pentagonal dodecahedra surrounding {Cu(12)} icosahedra with single Sn atoms at the center. Na(12)Cu(12)Sn(21) and K(12)Cu(12)Sn(21) were characterized by single-crystal XRD studies, and the successful synthesis of analogous A-Cu-Sn compounds with A = Rb and Cs is deduced from powder XRD data. The isotypic A(12)Cu(12)Sn(21) phases crystallize in the cubic space group Pn ̅3m (No. 224), with the Cu-Sn clusters adopting a face centered cubic arrangement. A formal charge of 12- can be assigned to the {Sn@Cu(12)@Sn(20)} cluster unit, and the interpretation of the title compounds as salt-like intermetallic phases featuring discrete anionic intermetalloid [Sn@Cu(12)@Sn(20)](12-) clusters separated by alkali metal cations is supported by electronic structure calculations. For both Na(12)Cu(12)Sn(21) and K(12)Cu(12)Sn(21), DFT band structure calculations (TB-LMTO-ASA) reveal a band gap. The discrete [Sn@Cu(12)@Sn(20)](12-) cluster is analyzed in consideration of the molecular orbitals obtained from hybrid DFT calculations (Gaussian 09) for the cluster anion. The [Sn@Cu(12)@Sn(20)](12-) cluster MOs can be classified with labels indicating the numbers of radial and angular nodes, in the style of spherical shell models of cluster bonding. © 2011 American Chemical Society

Barriers in the Physics Pipeline from K-12 to Tenure

NASA Astrophysics Data System (ADS)

Kilburn, Micha

2016-09-01

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).

2018-05-14

Here, we address the function of protein phosphatase 6 (PP6) loss on K-ras-initiated tumorigenesis in keratinocytes. To do so, we developed tamoxifen-inducible double mutant (K-ras G12D -expressing and Ppp6c-deficient) mice in which K-ras G12D expression is driven by the cytokeratin 14 (K14) promoter. Doubly-mutant mice showed early onset tumor formation in lip, nipples, external genitalia, anus and palms, and had to be sacrificed by three weeks after induction by tamoxifen, while comparably-treated K-ras G12D -expressing mice did not. HE-staining of lip tumors before euthanasia revealed that all were papillomas, some containing focal squamous cell carcinoma. Immunohistochemical analysis of lip of doubly-mutant versus K-ras G12D mice revealed that cell proliferation and cell size increased approximately two-fold relative to K-ras G12D -expressing mutants, and epidermal thickness of lip tissue greatly increased relative to that seen in K-ras G12D only mice. Moreover, AKT phosphorylation increased in K-ras G12D -expressing/Ppp6c-deficient cells, as did phosphorylation of the downstream effectors 4EBP1, S6, and GSK3, suggesting that protein synthesis and survival signals are enhanced in lip tissues of doubly-mutant mice. Finally, increased numbers of K14-positive cells were present in the suprabasal layer of doubly-mutant mice, indicating abnormal keratinocyte differentiation, and γH2AX-positive cells accumulated, indicating perturbed DNA repair. Taken together, Ppp6c deficiency enhances K-ras G12D -dependent tumor promotion. This article is protected by copyright. All rights reserved. This article is protected by copyright.

The structure of hexadeca-mu-acetato-tetraaquadodeca-mu(3)-oxo-dodecamanganese bis(acetic acid) tetrahydrate, [Mn(12)O(12)(CH(3)COO)(16)(H(2)O)(4)] x 2CH(3)COOH x 4H(2)O, known as Mn(12)-acetate, has been determined at 83 (2) K by X-ray diffraction methods. The fourfold (S(4)) molecular symmetry is disrupted by a strong hydrogen-bonding interaction with the disordered acetic acid molecule of solvation, which displaces one of the acetate ligands in the cluster. Up to six Mn(12) isomers are potentially present in the crystal lattice, which differ in the number and arrangement of hydrogen-bonded acetic acid molecules. These results considerably improve the structural information available on this molecular nanomagnet, which was first synthesized and characterized by Lis [Acta Cryst. (1980), B36, 2042-2046].

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

NASA Technical Reports Server (NTRS)

Lindberg, Robert E.; Pinelli, Thomas E.; Batterson, James G.

2008-01-01

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.

2003-12-01

The World Wide Web can be a powerful tool for reaching the public as well as students and teachers around the world, supporting both formal and informal science education. The Windows to the Universe Project, initiated in 1995, provides a case study of approaches for the use of the web to support earth and space science education and literacy efforts. Through the use of innovative approaches such as easy to use design, multi-level content, and science concepts presented in a broader background context that includes connections to culture and the humanities, Windows to the Universe is an accessible format for individuals of various ages and learning styles. A large global audience regularly uses the web site to learn about earth and space science as well as related humanities content such as myths from around the world. User surveys show that the site has over 4 millions users per year, 65 percent of which are K-12 teachers and students. Approximately 46 percent of users access the site once per week or more. Recently, we have had the opportunity to expand our efforts while we continue to update existing content based on new scientific findings and events. Earth science content on Windows to the Universe is currently growing with a new geology section and development efforts are underway to expand our space weather content with a new curriculum. Educational games allow users to learn about space in a playful context, and an online journaling tool further integrates literacy into the learning experience. In addition, we are currently translating the entire Windows to the Universe web site into Spanish. We have included educators in the project as co-designers from its inception, and by aggressively utilizing and providing professional development opportunities for teachers, the web site is now used in thousands of classrooms around the world. In the past year we have continued to support K-12 educators by adding to our suite of classroom activities and leading

Using a Non-Equivalent Groups Quasi Experimental Design to Reduce Internal Validity Threats to Claims Made by Math and Science K-12 Teacher Recruitment Programs

NASA Astrophysics Data System (ADS)

Moin, Laura

2009-10-01

The American Recovery and Reinvestment Act national policy established in 2009 calls for ``meaningful data'' that demonstrate educational improvements, including the recruitment of high-quality teachers. The scant data available and the low credibility of many K-12 math/science teacher recruitment program evaluations remain the major barriers for the identification of effective recruitment strategies. Our study presents a methodology to better evaluate the impact of recruitment programs on increasing participants' interest in teaching careers. The research capitalizes on the use of several control groups and presents a non-equivalent groups quasi-experimental evaluation design that produces program effect claims with higher internal validity than claims generated by current program evaluations. With this method that compares responses to a teaching career interest question from undergraduates all along a continuum from just attending an information session to participating (or not) in the recruitment program, we were able to compare the effect of the program in increasing participants' interest in teaching careers versus the evolution of the same interest but in the absence of the program. We were also able to make suggestions for program improvement and further research. While our findings may not apply to other K-12 math/science teacher recruitment programs, we believe that our evaluation methodology does and will contribute to conduct stronger program evaluations. In so doing, our evaluation procedure may inform recruitment program designers and policy makers.

2012-06-01

It has recently been shown that pathogens with a limited capacity for sessile growth (like some Escherichia coli O157 strains) can benefit from the presence of other bacteria and form mixed biofilms with companion strains. This study addresses the question whether pathogens may influence attached growth of E. coli non-pathogenic strains via secreted factors. We compared the biofilm-modulating effects of sterile stationary-phase culture media of a biofilm non-producing strain of E. coli O157:H, a laboratory biofilm-producing E. coli K-12 strain and a biofilm-forming strain of the pathogen Yersina enterocolitica O:3. Sessile growth was monitored as biomass (crystal violet assay), exopolysaccharide (ELLA) and morphology (scanning electron and confocal laser microscopy). With two of the E. coli K-12 strains stimulation of biofilm formation by all supernatants was achieved, but only the pathogens' secreted products induced biomass increase in some 'biofilm-deficient' K-12 strains. Lectin-peroxidase labeling indicated changes in colanic acid and poly-N-acetylglucosamine amounts in extracellular matrices. The contribution of indole, protein and polysaccharide to the biofilm-modulating activities of the supernatants was compared. Indole, in concentrations equal to those established in the supernatants, suppressed sessile growth in one K-12 strain. Proteinase K significantly reduced the stimulatory effects of all supernatants, indicating a prominent role of protein/peptide factor(s) in biofilm promotion. The amount of released polysaccharides (rPS) in the supernatants was quantitated then comparable quantities of isolated rPS were applied during biofilm growth. The three rPS had notable strain-specific effects with regard to both the strain-source of the rPS and the E. coli K-12 target strain.

Glucose and creatinine are two of the most frequently measured substances in human blood/serum for assessing the health status of individuals. Because of their clinical significance, CCQM-K11 glucose in human serum and CCQM-K12 creatinine in human serum were the fourth and fifth key comparisons (KCs) performed by the Organic Analysis Working Group (OAWG). These KCs were conducted in parallel and were completed in 2001. The initial subsequent KCs for glucose, CCQM-K11.1, and creatinine, CCQM-K12.1, were completed in 2005. Measurements for the next KCs for these two measurands, CCQM-K11.2 and CCQM-K12.2, were completed in 2013. While designed as subsequent KCs, systematic discordances between the participants' and the anchor institution's results in both comparisons lead the OAWG to request reference results from two experienced laboratories that had participated in the 2001 comparisons. Based on the totality of the available information, the OAWG converted both CCQM-K11.2 and CCQM-K12.2 to 'Track C' KCs where the key comparison reference value is estimated by consensus. These comparisons highlighted that carrying out comparisons for complex chemical measurements and expecting to be able to treat them under the approaches used for formal CIPM subsequent comparisons is not an appropriate strategy. The approach used here is a compromise to gain the best value from the comparison; it is not an approach that will be used in the future. Instead, the OAWG will focus on Track A and Track C comparisons that are treated as stand-alone entities. Participation in CCQM-K11.2 demonstrates a laboratory's capabilities to measure a polar (pKow > 2), low molecular mass (100 g/mol to 500 g/mol) metabolite in human serum at relatively high concentrations (0.1 mg/g to 10 mg/g). Participation in CCQM-K12.2 demonstrates capabilities to measure similar classes of metabolites at relatively low concentrations (1 μg/g to 30 μg/g). The capabilities required for the analysis of complex

Survey on Teaching Science to K-12 Students with Disabilities: Teacher Preparedness and Attitudes

NASA Astrophysics Data System (ADS)

Kahn, Sami; Lewis, Anna R.

2014-12-01

Students with disabilities are increasingly included in general education science classrooms and are expected to demonstrate academic proficiency on standardized assessments. Teacher preparation and attitudes have been cited as major factors contributing to either the success or failure of students with disabilities in science. In order to assess the current state of what could be facilitative or inhibitory influences, a national online survey to which 1,088 K-12 science teachers responded was conducted. Mixed methods' analyses suggest that science teachers receive little formal training and feel underprepared to teach students with disabilities. Results identify specific gaps in science teachers' education, as well as attitudinal and institutional barriers that may inhibit students with disabilities' success. However, science teachers remain highly receptive to training and collaboration. Implications for science teacher education are discussed.

Vitamin K1 injection induces severe dose-related anaphylactoid reactions and overdose for the treatment of vitamin K deficiency. We aimed to find an optimal and small dose of vitamin K1 injection to treat vitamin K deficiency and avoid anaphylactoid reactions in animal. Rats were administered a vitamin K-deficient diet and gentamicin to establish vitamin K deficiency model. Behaviour tests were performed in beagle dogs to observe anaphylactoid reactions. The results showed an increased protein induced by vitamin K absence or antagonist II (PIVKA-II) levels, a prolonging of prothrombin time (PT) and activated partial thromboplastin time (APTT) and a decrease in vitamin K-dependent coagulation factor (F) II, VII, IX and X activities in the model group. In vitamin K1 0.01 mg/kg group, the liver vitamin K1 levels increased fivefold and the liver vitamin K2 levels increased to the normal amount. Coagulation markers PT, APTT, FVII and FIX activities returned to normal. Both in the 0.1 and 1.0 mg/kg vitamin K1 groups, coagulation functions completely returned to normal. Moreover, the amount of liver vitamin K1 was 40 (0.1 mg/kg) or 100 (1.0 mg/kg) times as in normal. Vitamin K2 was about 4 (0.1 mg/kg) or 5 (1.0 mg/kg) times as the normal amount. There was no obvious anaphylactoid symptom in dogs with the dose of 0.03 mg/kg, which is equivalent to the dose of 0.01 mg/kg in rats. These results demonstrated that a small dose of vitamin K1 is effective to improve vitamin K deficiency and to prevent anaphylactoid reactions, simultaneously. © 2017 Société Française de Pharmacologie et de Thérapeutique.

Direction-Finding Measurements of Heliospheric 2-3 kHz Radio Emissions

NASA Technical Reports Server (NTRS)

Gurnett, Donald A.

1998-01-01

Using data from the Voyager 1 plasma wave instrument, a series of direction-finding measurements is presented for the intense 1992-93 heliospheric 2- to 3-kHz radio emission event, and several weaker events extending into 1994. Direction-finding measurements can only be obtained during roll maneuvers, which are performed about once every three months. Two parameters can be determined from the roll-induced intensity modulation, the azimuthal direction of arrival (measured around the roll axis), and the modulation index (the peak-to-peak amplitude divided by the peak amplitude). Measurements were made at two frequencies, 1.78 and 3.11 kHz. No roll modulation was observed at 1.78 kHz, which is consistent with an isotropic source at this frequency. In most cases an easily measurable roll modulation was detectable at 3.11 kHz. Although the azimuth angles have considerable scatter, the directions of arrival at 3.11 kHz can be organized into three groups, each of which appears to be associated with a separate upward drifting feature in the radio emission spectrum. The first group, which is associated with the main 1992-93 event, is consistent with a source located near the nose of the heliosphere. The remaining two groups, which occur after the main 1992-93 event, have azimuth angles well away from the nose of the heliosphere. The modulation indexes vary over a large range, from 0.06 to 0.61, with no obvious trend. Although the variations in the directions of arrival and modulation indicies appear to reflect changes in the position and angular size of the source, it is also possible that they could be caused by refraction or scattering due to density structures in the solar wind.

Active commuting among K-12 educators: a study examining walking and biking to work.

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. 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. 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. 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.

Role of alkali carbonate and salt in topochemical synthesis of K1/2Na1/2NbO3 and NaNbO3 templates

Lee, Jae-Seok; Jeon, Jae-Ho; Choi, Si-Young

2013-11-01

Since the properties of lead-free piezoelectric materials have thus far failed to meet those of lead-based materials, either chemical doping or morphological texturing should be employed to improve the piezoelectric properties of lead-free piezoelectric ceramics. The goal of this study was to synthesize plate-like K1/2Na1/2NbO3 and NaNbO3 particles, which are the most favorable templates for morphological texturing of K1/2Na1/2NbO3 ceramics. To achieve this goal, Bi2.5Na3.5Nb5O18 precursors in a plate-like shape were first synthesized and subsequently converted into K1/2Na1/2NbO3 or NaNbO3 particles that retain the morphology of Bi2.5Na3.5Nb5O18. In this study, we found that sodium or potassium carbonate does not play a major role in converting the Bi2.5Na3.5Nb5O18 precursor to K1/2Na1/2NbO3 or NaNbO3, on the contrary to previous reports; however, the salt contributes to the conversion reaction. All synthesis processes have been performed via a molten salt method, and scanning electron microscopy, scanning probe microscopy, and inductively coupled plasma mass spectroscopy were used to characterize the synthesized K1/2Na1/2NbO3 or NaNbO3 templates.

A network model for biofilm development in Escherichia coli K-12.

PubMed

Shalá, Andrew A; Restrepo, Silvia; González Barrios, Andrés F

2011-09-22

In nature, bacteria often exist as biofilms. Biofilms are communities of microorganisms attached to a surface. It is clear that biofilm-grown cells harbor properties remarkably distinct from planktonic cells. Biofilms frequently complicate treatments of infections by protecting bacteria from the immune system, decreasing antibiotic efficacy and dispersing planktonic cells to distant body sites. In this work, we employed enhanced Boolean algebra to model biofilm formation. The network obtained describes biofilm formation successfully, assuming - in accordance with the literature - that when the negative regulators (RscCD and EnvZ/OmpR) are off, the positive regulator (FlhDC) is on. The network was modeled under three different conditions through time with satisfactory outcomes. Each cluster was constructed using the K-means/medians Clustering Support algorithm on the basis of published Affymetrix microarray gene expression data from biofilm-forming bacteria and the planktonic state over four time points for Escherichia coli K-12. The different phenotypes obtained demonstrate that the network model of biofilm formation can simulate the formation or repression of biofilm efficiently in E. coli K-12.
