    Lennart M. Roesner

    2014-08-01

    Full Text Available Mutations in human DNA mismatch repair (MMR genes are commonly associated with hereditary nonpolyposis colorectal cancer (HNPCC. MLH1 protein heterodimerizes with PMS2, PMS1, and MLH3 to form MutLα, MutLβ, and MutLγ, respectively. We reported recently stable expression of GFP-linked MLH3 in human cell lines. Monitoring these cell lines during the cell cycle using live cell imaging combined with confocal microscopy, we detected accumulation of MLH3 at the centrosomes. Fluorescence recovery after photobleaching (FRAP revealed high mobility and fast exchange rates at the centrosomes as it has been reported for other DNA repair proteins. MLH3 may have a role in combination with other repair proteins in the control of centrosome numbers.

  14. Contemporary Education for Public Administration

    Directory of Open Access Journals (Sweden)

    Ivan Koprić

    2007-01-01

    Full Text Available The paper examines the development of contemporary administrative education, as a crucial criterion without which it is not possible to achieve professionalism in public administration. While the term professionalism has a variety of meanings, today it is largely deemed that specific educational preparation is a foundation without which other elements of professionalism in public administration cannot be achieved. The level of professionalism, competence, education and knowledge thus become critical variables of administration reforms in transitional countries. Afterwards, the author examines the trends in the development of contemporary administrative education, pointing particularly to the importance of establishing a coherent, vertically passable system, i.e. a system which encompasses all levels of education – from secondary school education to doctoral studies. In this matter, one of the most important features in the development of administrative studies is their diversification, with simultaneous strengthening of the general administrative profile. Thus, the general administrative profile becomes modified, updated and extended by new teaching disciplines. In the final section of the paper, the author addresses the performance of administrative education in Croatia, pointing to its underdevelopment. Indeed, the author suggests that there are no sustainable results of reforms without the training of staff for administration.

    The ARES Directorate education team is charged with translating the work of ARES scientists into content that can be used in formal and informal K-12 education settings and assisting with public outreach. This is accomplished through local efforts and national partnerships. Local efforts include partnerships with universities, school districts, museums, and the Lunar and Planetary Institute (LPI) to share the content and excitement of space science research. Sharing astromaterials and exploration science with the public is an essential part of the Directorate's work. As a small enclave of physical scientists at a NASA Center that otherwise emphasizes human space operations and engineering, the ARES staff is frequently called upon by the JSC Public Affairs and Education offices to provide presentations and interviews. Scientists and staff actively volunteer with the JSC Speaker's Bureau, Digital Learning Network, and National Engineers Week programs as well as at Space Center Houston activities and events. The education team also participates in many JSC educator and student workshops, including the Pre-Service Teacher Institute and the Texas Aerospace Scholars program, with workshop presentations, speakers, and printed materials.

  16. Digital publics and participatory education

    Directory of Open Access Journals (Sweden)

    Brian J. McNely

    2010-10-01

    Full Text Available This article—a collaborative exploration between instructors, students, and members of the broader, digital classroom community—explores how the strategic incorporation of sociotechnical networks and digital technologies facilitates literate practices that extend the classroom in productive ways. The article builds toward coauthors’ reflective practices (Schön, 1983, or “participatory perspectives”, had during an undergraduate English Studies course at a mid-sized, public, American university. Specifically, participants argue that these literate practices afforded not just information sharing, but the opening up of a traditional classroom to include broader digital publics and collaborative knowledge work (Spinuzzi, 2006. Toward this end, we ground literate practice in scholarship that attends to public writing in online spaces, and theoretically frame our argument using Jenkins et al.’s (2006 principles of participatory education. We then detail the specific curricular approach deliberately designed to create digitally connected publics and end with generalizable significance of coauthors’ participatory perspectives.

    The Large Synoptic Survey Telescope (LSST) will conduct a 10-year wide, fast, and deep survey of the night sky starting in 2022. LSST Education and Public Outreach (EPO) will enable public access to a subset of LSST data so anyone can explore the universe and be part of the discovery process. LSST EPO aims to facilitate a pathway from entry-level exploration of astronomical imagery to more sophisticated interaction with LSST data using tools similar to what professional astronomers use. To deliver data to the public, LSST EPO is creating an online Portal to serve as the main hub to EPO activities. The Portal will host an interactive Skyviewer, access to LSST data for educators and the public through online Jupyter notebooks, original multimedia for informal science centers and planetariums, and feature citizen science projects that use LSST data. LSST EPO will engage with the Chilean community through Spanish-language components of the Portal and will partner with organizations serving underrepresented groups in STEM.

    2004-01-01

    Full Text Available Education services also define the activities of Slovene public libraries. In planning targeted services they are often faced with development lagging. The accelerated progress in this field also reminds them of their lagging and points to a very uneven development and quality level of library activities in the various environments they are centered in. Perhaps due to such conditions public libraries do not excell in developing activities to satisfy education needs of their users. Even so, some successful cases point to the fact that libraries know how to act and could be successful under suitable conditions. The article presents an overview on how the law-defined needs for liferlong education (learning, education of users and information literacy, are meet through aquisition policies and through the realisation of different events taking into account the various levels of literacy of the participating population. The analysis of available reports and data point to the fact that libraries could be more successful if supported by increased expert help backed by financial aid.

    2017-01-01

    With special attention to Denmark, this article discusses to what degree religious education in public school in the Scandinavian countries, often said to be among the frontrunners as regards non-confessional religious education, reflects and accommodates an increased religious pluralism as well...... the 'repoliticization' and 'securitization' of religion (with special regard to Islamophobia, Islam and immigrant Muslim minorities), concludes, inter alia, that parts of the RE curricula do not just include a wider variety of religions but also helps to counter, if not stop, changes that have to do with the new...... plurality of religions. The analysis indicates that religious education is meant to serve the promotion of social cohesion by way of promoting knowledge and understanding of the new multi-religious world, at the same time as it continues to promote and propagate, for example, Danish culture as Christian...

  1. Public Education and Radioactive Waste

    International Nuclear Information System (INIS)

    Sarten, S.

    2009-01-01

    Throughout the country the mention of anything nuclear or the word radiation ignites fear in the minds of many Americans. Political hype, news stories and the lack of basic understanding about nuclear power and radiation causes many people to reject what they do not understand. Often little, if any, thought may have been given to nearby nuclear weapons facilities where family members and neighbors were gainfully employed at these sites. As older nuclear facilities are closed being a result of the end of the Cold War, with indications that radioactive materials might be transported to other parts of the country, the public in expressing concern. It is important that the public have an understanding of how these materials are handled to insure public safety. It becomes important that both the companies handling these materials and the U.S. Department of Energy create an environment that will involve community participation in developing strategies that will promote and support an understanding of how radioactive wastes will be packaged, transported, and disposed. This is being performed in Oak Ridge, TN. through the efforts of the Oak Ridge Site Specific Advisory Board (ORSSAB). The ORSSAB is a DOE sponsored board of private citizens from all walks of life and professionalism's. The objective of this paper is to offer suggestions as to how public confidence, through education about nuclear, radioactive and associated and wastes are effectively handle the problems related to waste disposal, removal or on-site storage. It is essential that the public fully understand and become involved in the need for the reduction of the waste stream volumes and the technical problems being faced in reaching this goal. The effort of gaining public understanding and support of this important task cannot be limited to just those within close proximity to the facility presently housing these materials, but must extend to those outlying areas and along any potential route that might be

  2. Public education in cancer prevention.

    Science.gov (United States)

    Van Parijs, L G

    1986-01-01

    Life-style is now recognized as a main determinant of cancer risk. Public education is an important component of cancer control programmes and has been shown to be effective in leading to life-style changes. Four basic types of education programmes are reviewed: for increasing the public's awareness of cancer, for changing specific risk behaviour (such as stopping smoking), for learning self-examination skills (such as breast self-examination), and for promoting early cancer detection in the community.To change human behaviour it is best to approach the risk habit through the same forces that develop and sustain the habit. Simply giving information of an association between specific habits and cancer, even if repeated several times, will lead to increased public awareness and encourage some to make a minimal effort to change their behaviour, but in general the new habit does not persist and continuing and intensifying this approach are ineffective. An alternative strategy utilizes socially active forces to support the prevention practice and remove possible barriers to action. For example, an antismoking programme should create a favourable social image of the non-smoker. Although a culturally and socially relevant mass media campaign can influence knowledge and beliefs and induce people to participate in a screening activity, this needs to be supplemented over a period of time by personal contact methods, such as group discussions, telephone conversations and home visits, in order to promote a regular screening habit. Contrary to popular opinion, mass communication methods can be expensive on a per person cost-effectiveness basis because of low participation rates and weakness in sustaining healthy behaviour.

    2018-04-12

    PurposeConstitutional epimutations are an alternative to genetic mutations in the etiology of genetic diseases. Some of these epimutations, termed secondary, correspond to the epigenetic effects of cis-acting genetic defects transmitted to the offspring following a Mendelian inheritance pattern. In Lynch syndrome, a few families with such apparently heritable MLH1 epimutations have been reported so far.MethodsWe designed a long-range polymerase chain reaction next-generation sequencing strategy to screen MLH1 entire gene and applied it to 4 French families with heritable epimutations and 10 additional patients with no proven transmission of their epimutations.ResultsThis strategy successfully detected the insertion of an Alu element in MLH1 coding sequence in one family. Two previously unreported MLH1 variants were also identified in other epimutation carriers: a nucleotide substitution within intron 1 and a single-nucleotide deletion in the 5'-UTR. Detection of a partial MLH1 duplication in another family required multiplex ligation-dependent probe amplification technology. We demonstrated the segregation of these variants with MLH1 methylation and studied the functional consequences of these defects on transcription.ConclusionThis is the largest cohort of patients with MLH1 secondary epimutations associated with a broad spectrum of genetic defects. This study provides further insight into the complexity of molecular mechanisms leading to secondary epimutations.GENETICS in MEDICINE advance online publication, 12 April 2018; doi:10.1038/gim.2018.47.

    Lynch syndrome is a hereditary cancer syndrome caused by a constitutional mutation in one of the mismatch repair genes. The implementation of predictive testing and targeted preventative surveillance is hindered by the frequent finding of sequence variants of uncertain significance in these genes. We aimed to determine the pathogenicity of previously reported variants (c.-28A>G and c.-7C>T) within the MLH1 5'untranslated region (UTR) in two individuals from unrelated suspected Lynch syndrome families. We investigated whether these variants were associated with other pathogenic alterations using targeted high-throughput sequencing of the MLH1 locus. We also determined their relationship to gene expression and epigenetic alterations at the promoter. Sequencing revealed that the c.-28A>G and c.-7C>T variants were the only potentially pathogenic alterations within the MLH1 gene. In both individuals, the levels of transcription from the variant allele were reduced to 50% compared with the wild-type allele. Partial loss of expression occurred in the absence of constitutional epigenetic alterations within the MLH1 promoter. We propose that these variants may be pathogenic due to constitutional partial loss of MLH1 expression, and that this may be associated with intermediate penetrance of a Lynch syndrome phenotype. Our findings provide further evidence of the potential importance of noncoding variants in the MLH1 5'UTR in the pathogenesis of Lynch syndrome. © 2015 The Authors. **Human Mutation published by Wiley Periodicals, Inc.

    1997-01-01

    Despite the extensive regulatory concurrence regarding the need to educate the public in changing utility markets, the task of doing so remains one of the most salient and challenging tasks facing regulators. As they transition from an environment earmarked by ratebase rate-of-return regulation to the new more-competitive environment, regulators ponder the degree to which the public understands the new competitive environment, the impacts of this environment on their utility service and fees, and the roles, responsibilities, and the mission of the public utilities commission in context of the new regulatory environment. In an effort to mitigate potential fears, confusions, and withdrawal of public support, public utility commissions have begun the monumental task of educating the public and, in the process, repositioning the public utility commission in the eyes of the myriad of consumer, media, governmental, industry, and special interest groups often referred to as the public

    Constitutional epimutation of the two major mismatch repair genes, MLH1 and MSH2, has been identified as an alternative mechanism that predisposes to the development of Lynch syndrome. In the present work, we aimed to investigate the prevalence of MLH1 constitutional methylation in colorectal cancer (CRC) patients with abnormal expression of the MLH1 protein in their tumors. In a series of 38 patients who met clinical criteria for Lynch syndrome genetic testing, with loss of MLH1 expression in the tumor and with no germline mutations in the MLH1 gene (35/38) or with tumors presenting the BRAF p.Val600Glu mutation (3/38), we screened for constitutional methylation of the MLH1 gene promoter using methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) in various biological samples. We found four (4/38; 10.5%) patients with constitutional methylation in the MLH1 gene promoter. RNA studies demonstrated decreased MLH1 expression in the cases with constitutional methylation when compared with controls. We could infer the mosaic nature of MLH1 constitutional hypermethylation in tissues originated from different embryonic germ layers, and in one family we could show that it occurred de novo. We conclude that constitutional MLH1 methylation occurs in a significant proportion of patients who have loss of MLH1 protein expression in their tumors and no MLH1 pathogenic germline mutation. Furthermore, we provide evidence that MLH1 constitutional hypermethylation is the molecular mechanism behind about 3% of Lynch syndrome families diagnosed in our institution, especially in patients with early onset or multiple primary tumors without significant family history. © 2018 The Authors.

  20. The Saccharomyces cerevisiae Mlh1-Mlh3 heterodimer is an endonuclease that preferentially binds to Holliday junctions.

    Science.gov (United States)

    Ranjha, Lepakshi; Anand, Roopesh; Cejka, Petr

    2014-02-28

    MutLγ, a heterodimer of the MutL homologues Mlh1 and Mlh3, plays a critical role during meiotic homologous recombination. The meiotic function of Mlh3 is fully dependent on the integrity of a putative nuclease motif DQHAX2EX4E, inferring that the anticipated nuclease activity of Mlh1-Mlh3 is involved in the processing of joint molecules to generate crossover recombination products. Although a vast body of genetic and cell biological data regarding Mlh1-Mlh3 is available, mechanistic insights into its function have been lacking due to the unavailability of the recombinant protein complex. Here we expressed the yeast Mlh1-Mlh3 heterodimer and purified it into near homogeneity. We show that recombinant MutLγ is a nuclease that nicks double-stranded DNA. We demonstrate that MutLγ binds DNA with a high affinity and shows a marked preference for Holliday junctions. We also expressed the human MLH1-MLH3 complex and show that preferential binding to Holliday junctions is a conserved capacity of eukaryotic MutLγ complexes. Specific DNA recognition has never been observed with any other eukaryotic MutL homologue. MutLγ thus represents a new paradigm for the function of the eukaryotic MutL protein family. We provide insights into the mode of Holliday junction recognition and show that Mlh1-Mlh3 prefers to bind the open unstacked Holliday junction form. This further supports the model where MutLγ is part of a complex acting on joint molecules to generate crossovers in meiosis.

    MutLγ, a heterodimer of the MutL homologues Mlh1 and Mlh3, plays a critical role during meiotic homologous recombination. The meiotic function of Mlh3 is fully dependent on the integrity of a putative nuclease motif DQHAX2EX4E, inferring that the anticipated nuclease activity of Mlh1-Mlh3 is involved in the processing of joint molecules to generate crossover recombination products. Although a vast body of genetic and cell biological data regarding Mlh1-Mlh3 is available, mechanistic insights into its function have been lacking due to the unavailability of the recombinant protein complex. Here we expressed the yeast Mlh1-Mlh3 heterodimer and purified it into near homogeneity. We show that recombinant MutLγ is a nuclease that nicks double-stranded DNA. We demonstrate that MutLγ binds DNA with a high affinity and shows a marked preference for Holliday junctions. We also expressed the human MLH1-MLH3 complex and show that preferential binding to Holliday junctions is a conserved capacity of eukaryotic MutLγ complexes. Specific DNA recognition has never been observed with any other eukaryotic MutL homologue. MutLγ thus represents a new paradigm for the function of the eukaryotic MutL protein family. We provide insights into the mode of Holliday junction recognition and show that Mlh1-Mlh3 prefers to bind the open unstacked Holliday junction form. This further supports the model where MutLγ is part of a complex acting on joint molecules to generate crossovers in meiosis. PMID:24443562

    Loss of mismatch repair (MMR) function in sporadic colorectal cancer occurs most commonly because of inactivation of MLH1, and it causes an increase in mutation rate. However, it is uncertain whether loss of MMR alters any other cellular function. The aim of this study was to investigate the role of MMR in regulating cell numbers and apoptosis. MLH1 protein levels were manipulated by (a) cloning and forcibly expressing MLH1 in HCT116 (a cell line with MLH1 mutation) and RKO (a cell line with MLH1 silencing), and (b) knockdown of MLH1 in SW480 (a cell line with normal MMR function). Cell number and apoptotic bodies were measured in standard and 'high stress' (ie, after staurosporine exposure) conditions. Restoration of MLH1 function in HCT116 and RKO resulted in increased cell number (pculture conditions. However, on induction of apoptotic stress, restoration of MLH1 resulted in reduced cell numbers (pcontext dependent: in 'low stress' conditions it may act to inhibit apoptosis, while in 'high stress' conditions it may induce apoptosis. However, within the context of chromosomal instability, the effect of MLH1 on cell numbers is limited.

    Objectives (1) Evaluate peer-reviewed publications regarding education in otolaryngology since 2000. (2) Analyze publication trends as compared with overall otolaryngology publications. Study Design Bibliometric analysis. Setting Academic medical center. Subjects and Methods A search for articles regarding education in otolaryngology from 2000 to 2015 was performed with MEDLINE and EMBASE databases, yielding 1220 articles; 362 relevant publications were categorized by topic, subspecialty, subject, article type, and funding source. Impact factors for each journal by year were obtained, and trends of each category over time were analyzed. These were then compared with publication numbers and impact factors for all otolaryngology journals. Results From 2000 to 2015, publications in otolaryngology education increased more rapidly than the field of otolaryngology overall. The most published topics included operative skills training, surgical simulation, and professionalism/career development. Recently there has been a decline in publications related to residency administration and duty hours relative to other topics. Only 12.2% of publications reported a funding source, and only 12.2% of studies were controlled. Conclusion Recent trends in otolaryngology literature reflect an increasing focus on education; however, this work is underfunded and often lacks high-quality evidence.

  10. Effect of nuclear education on public attitude

    International Nuclear Information System (INIS)

    Ohnishi, Teruaki

    1995-01-01

    A method is proposed to assess the effect of nuclear education. In this method, the nuclear education is treated as a part of the activities for public acceptance (PA), and a unit PA activity is assumed to give the same effect on the public, in essence, as a unit of nuclear information given by the newsmedia. Moreover, the change of attitude to nuclear energy is assumed to originate from enhanced understanding which, in turn, is brought by the stimulus given by the nuclear education. With the values of constants determined by using the data in Japan, example calculations were made for the educational time b 0 and the infiltration rate of education into minors B as parameters. It became clear from this calculation that the attitude to nuclear energy formed in the age of school children plays an essential role in shaping future public opinion since it is held in individuals without any notable modification for a long time after its formation, and that the effect of nuclear education to minors emerges depending on the variables b 0 and B in a highly non-linear manner. It was also found that there exists an optimum condition for nuclear education to attain the maximum amelioration of public opinion under a given condition of man-power for educational workers.

  17. Public higher education in the Philippines

    Science.gov (United States)

    Cardozier, V. R.

    1984-06-01

    Clearly, the national government of the Philippines has decided to increase the number and comprehensiveness of its public colleges and universities. While private colleges and universities are likely to dominate higher education in the Philippines for the remainer of this century, it appears that public, tax-supported higher education will become increasingly available there. The Philippines is not a wealthy country but it is devoting a substantial portion of its national resources to public higher education. In 1983, higher education received 2.85 percent of the national budget, a figure that has been rising for years. Compared with some highly developed countries, this is not a large percentage, but for a country that has traditionally relied on private higher education, it is a major and growing investment in the public sector. While many of the better universities in the Philippines are private, many other private educational institutions are small and struggling. As their financial resources become more limited, and as less expensive, tax-supported higher education becomes increasingly available, a lot of the struggling private colleges will probably close. This process is also being hastened by actions of the government to upgrade quality, for example in the case of the many private colleges that developed after World War II. In an attempt to improve the academic quality of these marginal institutions, the Ministry of Education, Culture and Sports has been given extensive authority, and while its intrusion into private institutions has been modest by some measures, its requirements are affecting them all and will speed the demise of some. This is bound to lead to a stronger role for public higher education in the Philippines, a country that is striving diligently to improve the education and hence the quality of life of its people.

    2012-07-01

    In the winter of 2007-08 a new public-facing antimicrobial campaign was agreed by the Advisory Committee on Antimicrobial Resistance and Healthcare-Associated Infection (ARHAI) Education sub-Group (later divided into subgroups for professional and public education): it comprised posters with a positive message on how the public could help themselves when they had a cold. However, the poster campaign, used in isolation in England, did not improve antibiotic use; therefore, the Public Education sub-Group took forward educational approaches to change the behaviour of the public and health professionals. Professionals have been encouraged to give patients clear information about the likely duration of symptoms, self-care, and benefits and harms of antibiotics, reinforcing the public poster campaigns in surgeries, hospitals and pharmacies. Since 2008, campaigns have been launched in England to coincide with European Antibiotic Awareness Day (EAAD) on 18 November, using Department of Health and EAAD materials. Professional education has been facilitated by the 2008 National Institute for Health and Clinical Excellence respiratory tract infection delayed prescribing guidance for general practitioners. A toolkit of materials for medicines management teams, to facilitate good antimicrobial stewardship in primary care (ASPIC), is being taken forward by the Public Education sub-Group and professional societies. After advice from ARHAI, in 2009 the General Medical Council requested that all postgraduate deans and Royal Colleges ensure infection prevention and control and antimicrobial prescribing become standard practice implemented in all clinical settings, and that they are emphasized strongly in undergraduate and postgraduate medical training. ARHAI has also taken a keen interest in reviewing, advising and leading on a number of European Union initiatives dealing with professional education.

    Purpose The aim of this paper is to describe the experience and educational benefits of a course that has several unique educational design features. Design/methodology/approach This includes narrative description of faculty and student experience from participants in a flipped-instructional-design inter-professional education course. Findings "Improving Public Health - An Interprofessional Approach to Designing and Implementing Effective Interventions" is an undergraduate public health course open to students regardless of background. Its student activities mirror the real-life tasks and challenges of working in a public health agency, including team-building and leadership; problem and project definition and prioritization; evidence-finding and critical appraisal; written and oral presentation; and press interviews. Students successfully developed project proposals to address real problems in a wide range of communities and settings and refined those proposals through interaction with professionals from population and public health, journalism and library sciences. Practical implications Undergraduate public health education is a relatively new endeavor, and experience with this new approach may be of value to other educators. Originality/value Students in this course, journalism graduate students who conducted mock interviews with them and instructors who oversaw the course all describe unique aspects and related personal benefit from this novel approach.

    2001-08-01

    This report constitutes a part of a series of reports within project JADE, comparison of deposition methods. A comparison of the deposition methods MLH (Medium Long Holes with approximately 25 copper canisters emplaced in a horizontal deposition hole about 200 metres in length bored between central and side tunnels) and KBS-3 (copper canisters are emplaced in vertical deposition holes bored in the floors of horizontal tunnels) has earlier been performed and KBS-3 was judged to be more advantageous than MLH. However, the prerequisites for the comparison have changed with time and an updated evaluation of MLH was therefore required. In this report, the current knowledge of MLH is summarized with focus on geological prerequisites, methods for boring long, horizontal deposition holes, reinforcement and sealing, deposition and cost. Comparisons with KBS-3 are performed sequentially. An MLH-repository is judged to be more sensitive to ingress of water to the deposition holes during the deposition process. This implies that a MLH repository based on today's knowledge is basically recommended for bedrock with fairly low water baring capacity. It has been demonstrated that MLH has considerable economic potential compared to KBS-3. However, the method is judged to be more technically immature than KBS-3. Particularly, methods and equipment for deposition of canisters need to be developed further. Methods and equipment for deposition can be developed, which fulfill the demands on function and safety, in the near future. MLH cannot therefore be rejected as deposition method

  3. Public education through safety culture demonstration

    2005-01-01

    The activities relating to nuclear energy have been world widely opposed against, because there have existed scars in the past; atomic bombs and a few accidents in nuclear facilities. It cannot be denied that the most effective education of public is through Medias such as news or documentary on newspaper and television. Once such cases appeared to public, it is difficult to erase the bad pictures from their memory. Since education for public is mainly depending on media, it is recommended putting harder effort on dissemination of information on regulation and regulatory function to public. The regulatory function of each country is the key of safe utilization of nuclear energy. Since prime responsibility of maintenance and operation are rested on the operators. To achieve the goal of safety, regulatory authority's task now is emphasized on encouraging operators of nuclear facilities to implement their safety culture. This will reduce the probability of unwanted events and therefore raising credit of nuclear energy. (author)

    Full Text Available In the article the interrelationships between the types of dominating values in the society and corresponding consequences for higher education aims and objectives. In the context of the mentioned interrelationships, there are given the examples of studies offered by the USA and Daugavpils University, as well as the access to value structuring and typology found in scientific literature. The surveyed study results render the public evaluation on the instrumental and terminal values of the higher education. Authors pay a special attention to systemic view or four quadrant matrix use in the analysis of value formation process. Semantic analysis of the concept “knowledge” and hermeneutic interpretation depict the direct connection of the education with individual and collective values. By determining the values dominating in the public, one can predict its expectations in the field of education and adapt it to the necessary changes.

    Loss of DNA mismatch repair (MMR) in humans, mainly due to mutations in the hMLH1 gene, is linked to hereditary nonpolyposis colorectal cancer (HNPCC). Because not all MLH1 alterations result in loss of MMR function, accurate characterization of variants and their classification in terms of their effect on MMR function is essential for reliable genetic testing and effective treatment. To date, in vivo assays for functional characterization of MLH1 mutations performed in various model systems have used episomal expression of the modified MMR genes. We describe here a novel approach to determine accurately the functional significance of hMLH1 mutations in vivo, based on co-expression of human MLH1 and PMS2 in yeast cells. Yeast MLH1 and PMS1 genes, whose protein products form the MutLα complex, were replaced by human orthologs directly on yeast chromosomes by homologous recombination, and the resulting MMR activity was tested. The yeast strain co-expressing hMLH1 and hPMS2 exhibited the same mutation rate as the wild-type. Eight cancer-related MLH1 variants were introduced, using the same approach, into the prepared yeast model, and their effect on MMR function was determined. Five variants (A92P, S93G, I219V, K618R and K618T) were classified as non-pathogenic, whereas variants T117M, Y646C and R659Q were characterized as pathogenic. Results of our in vivo yeast-based approach correlate well with clinical data in five out of seven hMLH1 variants and the described model was thus shown to be useful for functional characterization of MLH1 variants in cancer patients found throughout the entire coding region of the gene.

    Full Text Available AbstractPurpose: The article explains the role of user education in public libraries based on the assessment of users’ educational needs in a selected public library. We present a part of the results of the needs assessment study conducted on users of the Ljubljana City Library (LCL. In this presentation, we focus on the thematic areas of users’ interest, the most appropriate time of day and the most appropriate period of the year for participating in education. The aim of presenting this information is to support the development of an appropriate adult education provision and an effective use of human, financial and material resources in public libraries.Methodology/approach: The basic research method used was descriptive and causal non- experimental. The study involved 943 adults LCL users who have filled in an online or a printed form of the questionnaire.Results: Results of data analysis showed that users express a greater degree of interest in the following course topics: travel, foreign languages, literature, public speaking and health. They express the lowest degree of interest in the topics: policy, motoring and mathematics. Afternoons and evenings suit them best, whereas the autumn and winter season are in their view the best time of the year for participating in education. The analysis also showed some statistically significant differences in relation to sex, age, status and educational level of the users.Research limitation: By the practical application of results the characteristics of the sample of users and the environment from which they come, as well as the shortcomings of the questionnaire as an instrument for data collection, have to be considered.Originality/practical implications: The data obtained are useful in preparing the basis of educational activities in LCL, as well as for the design of educational programs in other comparable public libraries and other providers of adult education.

    The objective of this paper is to inform about the aspects of radiation protection public policies concerning the public spheres and the ordinary population. It is known that information has been considered a very important good in several knowledge areas. However, the efficiency of their transmission mechanisms should be periodically evaluated, checking existing critical and stagnation points. Nuclear area can be mentioned as a historically typical case, where the public policies assume relevant importance as tool for promotion, control and education of the population in general. Considering the polemic nature of such subject, it is clear that there is a need for conducting the construction of educational contents taking in account the educator training necessities. The addressing of radiation protection aspects applied to nuclear techniques conducts, for example, to the awareness on the benefits of radiation and its industrial and medical applications, which are established considering the worldwide adopted basic principles of radiation protection. Such questions, concerned with (or related to) public policies, establish a link between radiation protection and education, themes explored in this article to provide a better view of the current Brazilian scenario.

    1977-01-01

    A brief review is given of the changes that took place in 1972-73 in public opinion and political views in Sweden, leading to new attitudes and increasing interest in matters is of energy policy. Although nuclear power was from the beginning the main issue, it became more and more widely recognized that a number of complex and technically difficult problems were involved. In late 1973 the Government decided to prepare a comprehensive energy policy programme for the period 1975-85 and to put this programme before Parliament in the spring of 1975. In order to involve the public in the decision making process, a public education programme was introduced in January 1974. The essentials of this programme are described. The main effort was provided by the adult education associations. These were given financial incentives to start energy study circles and prepared their own study material. Journalist seminars were also arranged. The paper then describes how the public, by its activities in the energy study circles, was given a possibility to influence the formulation of the new Swedish energy policy. It outlines the links between the educational efforts, the discussions in the study circles, and the standpoints ultimately taken by the different political parties on the key energy issues, especially as regards the future role of nuclear power. Finally, it also tries to evaluate to what extent this effort in education and involvement can be expected to react on the implementation of the energy policy programme and on future energy policy decisions

  17. Mlh2 is an accessory factor for DNA mismatch repair in Saccharomyces cerevisiae.

    Full Text Available In Saccharomyces cerevisiae, the essential mismatch repair (MMR endonuclease Mlh1-Pms1 forms foci promoted by Msh2-Msh6 or Msh2-Msh3 in response to mispaired bases. Here we analyzed the Mlh1-Mlh2 complex, whose role in MMR has been unclear. Mlh1-Mlh2 formed foci that often colocalized with and had a longer lifetime than Mlh1-Pms1 foci. Mlh1-Mlh2 foci were similar to Mlh1-Pms1 foci: they required mispair recognition by Msh2-Msh6, increased in response to increased mispairs or downstream defects in MMR, and formed after induction of DNA damage by phleomycin but not double-stranded breaks by I-SceI. Mlh1-Mlh2 could be recruited to mispair-containing DNA in vitro by either Msh2-Msh6 or Msh2-Msh3. Deletion of MLH2 caused a synergistic increase in mutation rate in combination with deletion of MSH6 or reduced expression of Pms1. Phylogenetic analysis demonstrated that the S. cerevisiae Mlh2 protein and the mammalian PMS1 protein are homologs. These results support a hypothesis that Mlh1-Mlh2 is a non-essential accessory factor that acts to enhance the activity of Mlh1-Pms1.

    Lynch syndrome (LS) is a tumor predisposing condition caused by constitutional defects in genes coding for components of the mismatch repair (MMR) apparatus. While hypermethylation of the promoter of the MMR gene MLH1 occurs in about 15% of colorectal cancer samples, it has also been observed as a constitutional alteration, in the absence of DNA sequence mutations, in a small number of LS patients. In order to obtain further insights on the phenotypic characteristics of MLH1 epimutation carriers, we investigated the somatic and constitutional MLH1 methylation status of 14 unrelated subjects with a suspicion of LS who were negative for MMR gene constitutional mutations and whose tumors did not express the MLH1 protein. A novel case of constitutional MLH1 epimutation was identified. This patient was affected with multiple primary tumors, including breast cancer, diagnosed starting from the age of 55 y. Investigation of her offspring by allele specific expression revealed that the epimutation was not stable across generations. We also found MLH1 hypermethylation in cancer samples from 4 additional patients who did not have evidence of constitutional defects. These patients had some characteristics of LS, namely early age at onset and/or positive family history, raising the possibility of genetic influences in the establishment of somatic MLH1 methylation.

  20. Innovating undergraduate pathology education through public engagement.

    2018-05-01

    The trends in modern undergraduate medical education focus on a patient-centred approach through problem-based learning over the traditional modular curriculum. Integrating pathology into this style of learning has resulted in the dilution of core scientific principles which may have contributed to reduced understanding and interest in the subject. We aim to innovate pathology education by utilising National Pathology Week which is organised by the Royal College of Pathologists to develop the public engagement model which empowers students to learn pathology by teaching the public. Through this model, we hope to generate a greater interest in pathology at both undergraduate and postgraduate stages of education. We obtained funding from the Royal College of Pathologists to organise National Pathology Week at Exeter Medical School and the Royal Devon & Exeter Hospital. We involved 125 undergraduate student volunteers from health-related courses. We designed a curriculum aiming to educate both students and public on current topics such as cancer screening programmes, antibiotic resistance, diagnosis of inflammatory bowel disease and the role of pathologists. We hosted 15 pathologists, biomedical scientists and microbiologists to engage with students, share experiences and offer an insight into their careers. Through this project, we interacted with over 500 members of the public and 150 school students. The medical student volunteers developed a range of skills including competent use of microscopes to visualise pathology slides, effective communication with lay audiences to teach pathology and understanding of the clinical application of pathology. We believe the public engagement model of teaching undergraduate students has the potential to develop a greater interest in pathology whilst benefitting the wider community.

    Full Text Available In the context of the so-called digital culture, this paper discusses the issue of education and the political implications of the distance learning expansion movement in Brazil. In addition to the advances in the democratization of the access to information through the mediation of information and communication technologies (ICTs, which should be recognized as an effort to spread a certain “political culture”, this does not necessarily mean, as Habermas (2003b recalls, that the effective political participation of citizens is assured, especially in light of recurrent dislocation between the political public sphere and civil society. What are the interests behind the phenomenon of digitization of culture? And what is the purpose of education in this new cultural context? As an expression of contemporary social life, digital culture generates structural changes, not only in the form of transmission and access to culture, but also in the very concept and attitude towards culture, with decisive political implications for education. That leads us to think, for example, about the differences between the concepts of education present in the classical Greek Paideia culture, in the modern culture of Bildung, and in the contemporary educational model increasingly subservient to the ICTs we now have.

  6. Mlh1-Mlh3, a Meiotic Crossover and DNA Mismatch Repair Factor, Is a Msh2-Msh3-stimulated Endonuclease*

    Crossing over between homologous chromosomes is initiated in meiotic prophase in most sexually reproducing organisms by the appearance of programmed double strand breaks throughout the genome. In Saccharomyces cerevisiae the double-strand breaks are resected to form three prime single-strand tails that primarily invade complementary sequences in unbroken homologs. These invasion intermediates are converted into double Holliday junctions and then resolved into crossovers that facilitate homolog segregation during Meiosis I. Work in yeast suggests that Msh4-Msh5 stabilizes invasion intermediates and double Holliday junctions, which are resolved into crossovers in steps requiring Sgs1 helicase, Exo1, and a putative endonuclease activity encoded by the DNA mismatch repair factor Mlh1-Mlh3. We purified Mlh1-Mlh3 and showed that it is a metal-dependent and Msh2-Msh3-stimulated endonuclease that makes single-strand breaks in supercoiled DNA. These observations support a direct role for an Mlh1-Mlh3 endonuclease activity in resolving recombination intermediates and in DNA mismatch repair. PMID:24403070

    Defects in the DNA mismatch repair (MMR) protein MLH1 are frequently observed in sporadic and hereditary colorectal cancers (CRC). Affected tumors generate much less metastatic potential than the MLH1 proficient forms. Although MLH1 has been shown to be not only involved in postreplicative MMR but also in several MMR independent processes like cytoskeletal organization, the connection between MLH1 and metastasis remains unclear. We recently identified non-erythroid spectrin αII (SPTAN1), a scaffolding protein involved in cell adhesion and motility, to interact with MLH1. In the current study, the interaction of MLH1 and SPTAN1 and its potential consequences for CRC metastasis was evaluated. Nine cancer cell lines as well as fresh and paraffin embedded colon cancer tissue from 12 patients were used in gene expression studies of SPTAN1 and MLH1. Co-expression of SPTAN1 and MLH1 was analyzed by siRNA knock down of MLH1 in HeLa, HEK293, MLH1 positive HCT116, SW480 and LoVo cells. Effects on cellular motility were determined in MLH1 deficient HCT116 and MLH1 deficient HEK293T compared to their MLH1 proficient sister cells, respectively. MLH1 deficiency is clearly associated with SPTAN1 reduction. Moreover, siRNA knock down of MLH1 decreased the mRNA level of SPTAN1 in HeLa, HEK293 as well as in MLH1 positive HCT116 cells, which indicates a co-expression of SPTAN1 by MLH1. In addition, cellular motility of MLH1 deficient HCT116 and MLH1 deficient HEK293T cells was impaired compared to the MLH1 proficient sister clones. Consequently, overexpression of SPTAN1 increased migration of MLH1 deficient cells while knock down of SPTAN1 decreased cellular mobility of MLH1 proficient cells, indicating SPTAN1-dependent migration ability. These data suggest that SPTAN1 levels decreased in concordance with MLH1 reduction and impaired cellular mobility in MLH1 deficient colon cancer cells. Therefore, aggressiveness of MLH1-positive CRC might be related to SPTAN1.

  12. mlh3 mutations in baker's yeast alter meiotic recombination outcomes by increasing noncrossover events genome-wide.

    Directory of Open Access Journals (Sweden)

    Najla Al-Sweel

    2017-08-01

    Full Text Available Mlh1-Mlh3 is an endonuclease hypothesized to act in meiosis to resolve double Holliday junctions into crossovers. It also plays a minor role in eukaryotic DNA mismatch repair (MMR. To understand how Mlh1-Mlh3 functions in both meiosis and MMR, we analyzed in baker's yeast 60 new mlh3 alleles. Five alleles specifically disrupted MMR, whereas one (mlh3-32 specifically disrupted meiotic crossing over. Mlh1-mlh3 representatives for each class were purified and characterized. Both Mlh1-mlh3-32 (MMR+, crossover- and Mlh1-mlh3-45 (MMR-, crossover+ displayed wild-type endonuclease activities in vitro. Msh2-Msh3, an MSH complex that acts with Mlh1-Mlh3 in MMR, stimulated the endonuclease activity of Mlh1-mlh3-32 but not Mlh1-mlh3-45, suggesting that Mlh1-mlh3-45 is defective in MSH interactions. Whole genome recombination maps were constructed for wild-type and MMR+ crossover-, MMR- crossover+, endonuclease defective and null mlh3 mutants in an S288c/YJM789 hybrid background. Compared to wild-type, all of the mlh3 mutants showed increases in the number of noncrossover events, consistent with recombination intermediates being resolved through alternative recombination pathways. Our observations provide a structure-function map for Mlh3 that reveals the importance of protein-protein interactions in regulating Mlh1-Mlh3's enzymatic activity. They also illustrate how defective meiotic components can alter the fate of meiotic recombination intermediates, providing new insights for how meiotic recombination pathways are regulated.

  13. Association between MLH1 -93G>a polymorphism and risk of colorectal cancer.

    Directory of Open Access Journals (Sweden)

    Ting Wang

    Full Text Available The -93G>A (rs1800734 polymorphism located in the promoter of mismatch repair gene, MLH1, has been identified as a low-penetrance variant for cancer risk. Many published studies have evaluated the association between the MLH1 -93G>A polymorphism and colorectal cancer (CRC risk. However, the results remain conflicting rather than conclusive.The aim of this study was to assess the association between the MLH1 -93G>A polymorphism and the risk of CRC.To derive a more precise estimation of the association, a meta-analysis of six studies (17,791 cases and 13,782 controls was performed. Odds ratios (ORs and 95% confidence intervals (CIs were used to evaluate the strength of the association. Four of these published studies were performed on subjects of known microsatellite instability (MSI status. An additional analysis including 742 cases and 10,895 controls was used to assess the association between the MLH1 -93G>A polymorphism and the risk of MSI-CRC.The overall results indicated that the variant genotypes were associated with a significantly increased risk of CRC (AG versus GG: OR = 1.06, 95% CI = 1.01-1.11; AA/AG versus GG: OR = 1.06, 95% CI = 1.01-1.11. This increased risk was also found during stratified analysis of MSI status (AA versus GG: OR = 2.52, 95% CI = 1.94-3.28; AG versus GG: OR = 1.29, 95% CI = 1.10-1.52; AA/AG versus GG: OR = 1.45, 95% CI = 1.24-1.68; AA versusOR = 2.29, 95% CI = 1.78-2.96. Egger's test did not show any evidence of publication bias.Our results suggest that the MLH1 -93G>A polymorphism may contribute to individual susceptibility to CRC and act as a risk factor for MSI-CRC.

  14. The mismatch repair and meiotic recombination endonuclease Mlh1-Mlh3 is activated by polymer formation and can cleave DNA substrates in trans.

    2017-04-01

    Crossing over between homologs is initiated in meiotic prophase by the formation of DNA double-strand breaks that occur throughout the genome. In the major interference-responsive crossover pathway in baker's yeast, these breaks are resected to form 3' single-strand tails that participate in a homology search, ultimately forming double Holliday junctions (dHJs) that primarily include both homologs. These dHJs are resolved by endonuclease activity to form exclusively crossovers, which are critical for proper homolog segregation in Meiosis I. Recent genetic, biochemical, and molecular studies in yeast are consistent with the hypothesis of Mlh1-Mlh3 DNA mismatch repair complex acting as the major endonuclease activity that resolves dHJs into crossovers. However, the mechanism by which the Mlh1-Mlh3 endonuclease is activated is unknown. Here, we provide evidence that Mlh1-Mlh3 does not behave like a structure-specific endonuclease but forms polymers required to generate nicks in DNA. This conclusion is supported by DNA binding studies performed with different-sized substrates that contain or lack polymerization barriers and endonuclease assays performed with varying ratios of endonuclease-deficient and endonuclease-proficient Mlh1-Mlh3. In addition, Mlh1-Mlh3 can generate religatable double-strand breaks and form an active nucleoprotein complex that can nick DNA substrates in trans. Together these observations argue that Mlh1-Mlh3 may not act like a canonical, RuvC-like Holliday junction resolvase and support a novel model in which Mlh1-Mlh3 is loaded onto DNA to form an activated polymer that cleaves DNA.

    2014-11-24

    Methylation of the MLH1 promoter region has been suggested to be a major mechanism of gene inactivation in sporadic microsatellite instability-positive (MSI-H) colorectal cancers (CRCs). Recently, single-nucleotide polymorphism (SNP) in the MLH1 promoter region (MLH1-93G/A; rs1800734) has been proposed to be associated with MLH1 promoter methylation, loss of MLH1 protein expression and MSI-H tumors. We examined the association of MLH1-93G/A and six other SNPs surrounding MLH1-93G/A with the methylation status in 210 consecutive sporadic CRCs in Japanese patients. Methylation of the MLH1 promoter region was evaluated by Na-bisulfite polymerase chain reaction (PCR)/single-strand conformation polymorphism (SSCP) analysis. The genotype frequencies of SNPs located in the 54-kb region surrounding the MLH1-93G/A SNP were examined by SSCP analysis. Methylation of the MLH1 promoter region was observed in 28.6% (60/210) of sporadic CRCs. The proportions of MLH1-93G/A genotypes A/A, A/G and G/G were 26% (n=54), 51% (n=108) and 23% (n=48), respectively, and they were significantly associated with the methylation status (p=0.01). There were no significant associations between genotype frequency of the six other SNPs and methylation status. The A-allele of MLH1-93G/A was more common in cases with methylation than the G-allele (p=0.0094), especially in females (p=0.0067). In logistic regression, the A/A genotype of the MLH1-93G/A SNP was shown to be the most significant risk factor for methylation of the MLH1 promoter region (odds ratio 2.82, p=0.003). Furthermore, a haplotype of the A-allele of rs2276807 located -47 kb upstream from the MLH1-93G/A SNP and the A-allele of MLH1-93G/A SNP was significantly associated with MLH1 promoter methylation. These results indicate that individuals, and particularly females, carrying the A-allele at the MLH1-93G/A SNP, especially in association with the A-allele of rs2276807, may harbor an increased risk of methylation of the MLH1 promoter

    1991-12-01

    Commentary is provided on the implementation of China's Three Priorities in strengthening family planning (FP) for population control. The Three Priorities issued by the Party Central Committee of China and the State Council refers to the emphasis on 1) "publicity and education rather than economic disincentives," 2) contraception rather than induced abortion," and 3) "day to day management work rather than irregular campaigns." The expectations are that leaders at all levels should be active, steadfast, patient, and down to earth. Improvements in management lead to more constant, scientific, and systematic FP. Family planning should be voluntary. The achievement is not just population control but better relations with the Party and cadres, which leads to social stability and unity. The directives have been well thought out and are to be resolutely carried out. It was stressed in April 1991 by the General-Secretary and the Premier that coercion would not be tolerated in FP work. The confidence of the masses must be relied upon. The success of FP is guaranteed with the practice of these directives. Constancy of education and publicity is the key work. There should be a strong population awareness and the awareness of available resources/capita, and also an understanding and firm command of the principles and methods of better implementation. FP has an effect both on the fundamental interests of the country and immediate personal interests. The task is expected to be difficult because traditional ideas are still strong. The country is just at the beginning stages of socialism. A social security system is not a reality and farmer's educational attainment is not high. Productivity in the rural areas is underdeveloped. There is a contradiction between childbearing intentions of some farmers and the government requirements of FP. In order for the people to understand government FP policy, painstaking and meticulous education must be carried out to explain why FP is

  1. Gender issues in medical and public health education.

    Science.gov (United States)

    Wong, Y L

    2000-01-01

    There is no doubt that gender bias has been inherent in medical and public health education, research, and clinical practice. This paper discusses the central question for medical and public health educators viz. whether women's health concerns and needs could be best addressed by the conventional biomedical approach to medical and public health education, research, and practice. Gender inequalities in health and gender bias in medical and public health education are revealed. It is found that in most public health and prevention issues related to women's health, the core issue is male-female power relations, and not merely the lack of public health services, medical technology, or information. There is, thus, an urgent need to gender-sensitize public health and medical education. The paper proposes a gender analysis of health to distinguish between biological causes and social explanations for the health differentials between men and women. It also assessed some of the gender approaches to public health and medical education currently adopted in the Asia-Pacific region. It poses the pressing question of how medical and public health educators integrate the gender perspective into medical and public health education. The paper exhorts all medical and public health practitioners to explore new directions and identify innovative strategies to formulate a gender-sensitive curriculum towards the best practices in medicine and public health that will meet the health needs of women and men in the 21st century.

    Education and public engagement (EPE) is an essential part of astronomy's mission. New technologies, remote observing and robotic facilities are opening new possibilities for EPE. A number of projects (e.g., Telescopes In Education, MicroObservatory, Goldstone Apple Valley Radio Telescope and UNC's Skynet) have developed new infrastructure, a number of observatories (e.g., University of Arizona's "full-engagement initiative" towards its astronomy majors, Vatican Observatory's collaboration with high-schools) have dedicated their resources to practical instruction and EPE. Some of the facilities are purpose built, others are legacy telescopes upgraded for remote or automated observing. Networking among institutions is most beneficial for EPE, and its implementation ranges from informal agreements between colleagues to advanced software packages with web interfaces. The deliverables range from reduced data to time and hands-on instruction while operating a telescope. EPE represents a set of tasks and challenges which is distinct from research applications of the new astronomical facilities and operation modes. In this paper we examine the experience with several EPE projects, and some lessons and challenges for observatory operation.

    The Huntington's disease gene (HTT) CAG repeat mutation undergoes somatic expansion that correlates with pathogenesis. Modifiers of somatic expansion may therefore provide routes for therapies targeting the underlying mutation, an approach that is likely applicable to other trinucleotide repeat diseases. Huntington's disease Hdh(Q111) mice exhibit higher levels of somatic HTT CAG expansion on a C57BL/6 genetic background (B6.Hdh(Q111) ) than on a 129 background (129.Hdh(Q111) ). Linkage mapping in (B6x129).Hdh(Q111) F2 intercross animals identified a single quantitative trait locus underlying the strain-specific difference in expansion in the striatum, implicating mismatch repair (MMR) gene Mlh1 as the most likely candidate modifier. Crossing B6.Hdh(Q111) mice onto an Mlh1 null background demonstrated that Mlh1 is essential for somatic CAG expansions and that it is an enhancer of nuclear huntingtin accumulation in striatal neurons. Hdh(Q111) somatic expansion was also abolished in mice deficient in the Mlh3 gene, implicating MutLγ (MLH1-MLH3) complex as a key driver of somatic expansion. Strikingly, Mlh1 and Mlh3 genes encoding MMR effector proteins were as critical to somatic expansion as Msh2 and Msh3 genes encoding DNA mismatch recognition complex MutSβ (MSH2-MSH3). The Mlh1 locus is highly polymorphic between B6 and 129 strains. While we were unable to detect any difference in base-base mismatch or short slipped-repeat repair activity between B6 and 129 MLH1 variants, repair efficiency was MLH1 dose-dependent. MLH1 mRNA and protein levels were significantly decreased in 129 mice compared to B6 mice, consistent with a dose-sensitive MLH1-dependent DNA repair mechanism underlying the somatic expansion difference between these strains. Together, these data identify Mlh1 and Mlh3 as novel critical genetic modifiers of HTT CAG instability, point to Mlh1 genetic variation as the likely source of the instability difference in B6 and 129 strains and suggest that MLH1

    Willis, Y.A.

    1992-01-01

    This paper assumes that a stronger national commitment to public education on nuclear energy and, most particularly radioactive waste management, it needed to overcome public resistance to nuclear projects. Effective public education must become the superordinate goal uniting industry, government, professional societies, national laboratories and the educational community. Since instruction is labor intensive, we must search for more cost effective ways of achieving results. Therefore, this paper proposes: Collaborative training and educational strategies involving as many of the stakeholders as possible; and Innovative tools to improve the credibility, quality and cost effectiveness of education. This win-win approach can reduce the collective expenditures through cost-sharing, as well as the sharing of resources and products. It can close gaps in both in-house training and formal education. Finally, in public outreach, the joint approach addresses the politics of sponsorship by providing checks and balances, and thus improving credibility and public acceptance

    Between 10% and 15% of colorectal carcinomas demonstrate sporadic DNA mismatch-repair protein deficiency as a result of MLH1 promoter methylation and are thought to arise from sessile serrated adenomas, termed the serrated neoplasia pathway. Although the presence of the BRAF V600E mutation is indicative of a sporadic cancer, up to 30% to 50% of colorectal carcinomas with MLH1 promoter hypermethylation will lack a BRAF mutation. We report the clinicopathologic and molecular features of MLH1-deficient colorectal carcinoma with wild-type BRAF and MLH1 promoter hypermethylation (referred to as MLH1-hypermethylated BRAF wild-type colorectal carcinoma, n=36) in comparison with MLH1-deficient BRAF-mutated colorectal carcinoma (n=113) and Lynch syndrome-associated colorectal carcinoma (n=36). KRAS mutations were identified in 31% of MLH1-hypermethylated BRAF wild-type colorectal carcinomas compared with 0% of MLH1-deficient BRAF-mutated colorectal carcinomas and 37% of Lynch syndrome-associated colorectal carcinomas. When a precursor polyp was identified, MLH1-hypermethylated BRAF wild-type colorectal carcinomas arose from precursor polyps resembling conventional tubular/tubulovillous adenomas in contrast to MLH1-deficient BRAF-mutated colorectal carcinomas, which arose from precursor sessile serrated adenomas (PMLH1-hypermethylated BRAF wild-type colorectal carcinoma and MLH1-deficient BRAF-mutated colorectal carcinoma had a predilection for the right colon compared with Lynch syndrome-associated colorectal carcinoma (86% vs. 92% vs. 49%, P0.05). In conclusion, our results indicate that MLH1-hypermethylated BRAF wild-type colorectal carcinomas can harbor KRAS mutations and arise from precursor polyps resembling conventional tubular/tubulovillous adenomas.

    Few astronomical objects excite students more than big explosions and black holes. Gamma Ray Bursts (GRBs) are both: powerful explosions that signal the births of black holes. NASA's Swift satellite mission, set for launch in Fall 2004, will detect hundreds of black holes over its two-year nominal mission timeline. The NASA Education and Public Outreach (E/PO) group at Sonoma State University is leading the Swift E/PO effort, using the Swift mission to engage students in science and math learning. We have partnered with the Lawrence Hall of Science to create a ``Great Explorations in Math and Science" guide entitled ``Invisible Universe: from Radio Waves to Gamma Rays," which uses GRBs to introduce students to the electromagnetic spectrum and the scale of energies in the Universe. We have also created new standards-based activities for grades 9-12 using GRBs: one activity puts the students in the place of astronomers 20 years ago, trying to sort out various types of stellar explosions that create high-energy radiation. Another mimics the use of the Interplanetary Network to let students figure out the direction to a GRB. Post-launch materials will include magazine articles about Swift and GRBs, and live updates of GRB information to the Swift E/PO website that will excite and inspire students to learn more about space science.

    2015-01-01

    This article describes a framework and empirical evidence to support the argument that educational programs and policies are crucial public health interventions. Concepts of education and health are developed and linked, and we review a wide range of empirical studies to clarify pathways of linkage and explore implications. Basic educational expertise and skills, including fundamental knowledge, reasoning ability, emotional self-regulation, and interactional abilities, are critical components of health. Moreover, education is a fundamental social determinant of health - an upstream cause of health. Programs that close gaps in educational outcomes between low-income or racial and ethnic minority populations and higher-income or majority populations are needed to promote health equity. Public health policy makers, health practitioners and educators, and departments of health and education can collaborate to implement educational programs and policies for which systematic evidence indicates clear public health benefits. © The Author(s) 2015.

    Mismatch repair (MMR) enzymes have been shown to be deficient in prostate cancer (PCa). MMR can influence the regulation of tumor development in various cancers but their role on PCa has not been investigated. The aim of the present study was to determine the functional effects of the mutL-homolog 1 (MLH1) gene on growth of PCa cells. The DU145 cell line has been established as MLH1-deficient and thus, this cell line was utilized to determine effects of MLH1 by gene expression. Lack of MLH1 protein expression was confirmed by Western blotting in DU145 cells whereas levels were high in normal PWR-1E and RWPE-1 prostatic cells. MLH1-expressing stable transfectant DU145 cells were then created to characterize the effects this MMR gene has on various growth properties. Expression of MLH1 resulted in decreased cell proliferation, migration and invasion properties. Lack of cell growth in vivo also indicated a tumor suppressive effect by MLH1. Interestingly, MLH1 caused an increase in apoptosis along with phosphorylated c-Abl, and treatment with MLH1 siRNAs countered this effect. Furthermore, inhibition of c-Abl with STI571 also abrogated the effect on apoptosis caused by MLH1. These results demonstrate MLH1 protects against PCa development by inducing c-Abl-mediated apoptosis.

The importance of preparing a public health workforce with sufficient capacity and appropriate capabilities has been recognized by major organizations around the world (1. Champions for public health note that a suitably educated workforce is essential to the delivery of public health services, including emergency response to biological, manmade, and natural disasters, within countries and across the globe. No single repository offers a comprehensive compilation of who is teaching public health, to whom, and for what end. Moreover, no international consensus prevails on what higher education should entail or what pedagogy is optimal for providing the necessary education. Although health agencies, public or private, might project workforce needs, the higher level of education remains the sole responsibility of higher education institutions. The long-term goal of this study is to describe approaches to the education of the public health workforce around the world by identifying the peer-reviewed literature, published primarily by academicians involved in educating those who will perform public health functions. This paper reports on the first phase of the study: identifying and categorizing papers published in peer-reviewed literature between 2000 and 2015.

  5. The MLH1 ATPase domain is needed for suppressing aberrant formation of interstitial telomeric sequences.

    Jia, Pingping; Chai, Weihang

    2018-05-01

    Genome instability gives rise to cancer. MLH1, commonly known for its important role in mismatch repair (MMR), DNA damage signaling and double-strand break (DSB) repair, safeguards genome stability. Recently we have reported a novel role of MLH1 in preventing aberrant formation of interstitial telomeric sequences (ITSs) at intra-chromosomal regions. Deficiency in MLH1, in particular its N-terminus, leads to an increase of ITSs. Here, we identify that the ATPase activity in the MLH1 N-terminal domain is important for suppressing the formation of ITSs. The ATPase activity is also needed for recruiting MLH1 to DSBs. Moreover, defective ATPase activity of MLH1 causes an increase in micronuclei formation. Our results highlight the crucial role of MLH1's ATPase domain in preventing the aberrant formation of telomeric sequences at the intra-chromosomal regions and preserving genome stability.

    Lynch syndrome is an autosomal dominant inherited disease caused by germline mutations in mismatch repair genes. Analysis for microsatellite instability (MSI) and immunohistochemistry (IHC) of protein expressions of disease-associated genes is used to screen for Lynch syndrome in endometrial cancer patients. When losses of both MLH1 and PMS2 proteins are observed by IHC, MLH1 promoter methylation analysis is conducted to distinguish Lynch syndrome-associated endometrial cancer from sporadic cancer. Here we report a woman who developed endometrial cancer at the age of 49 years. She had a family history of colorectal cancer (first-degree relative aged 52 years) and stomach cancer (second-degree relative with the age of onset unknown). No other family history was present, and she failed to meet the Amsterdam II criteria for the diagnosis of Lynch syndrome. Losses of MLH1 and PMS2, but not MSH2 and MSH6, proteins were observed by IHC in endometrial cancer tissues. Because MLH1 promoter hypermethylation was detected in endometrial cancer tissue samples, the epigenetic silencing of MLH1 was suspected as the cause of the protein loss. However, because of the early onset of endometrial cancer and the positive family history, a diagnosis of Lynch syndrome was also suspected. Therefore, we provided her with genetic counseling. After obtaining her consent, MLH1 promoter methylation testing and genetic testing of peripheral blood were performed. MLH1 promoter methylation was not observed in peripheral blood. However, genetic testing revealed a large deletion of exon 5 in MLH1; thus, we diagnosed the presence of Lynch syndrome. Both MLH1 germline mutation and MLH1 promoter hypermethylation may be observed in endometrial cancer. Therefore, even if MLH1 promoter hypermethylation is detected, a diagnosis of Lynch syndrome cannot be excluded.

One of the key factors of the university success is to implement the diversification strategy into the overall academic strategy and mission of the higher education institution. The analysis recommends the performance-based funding system and public higher education institutions achieve certain performance indicators. The performance-based funding system will promote higher competitiveness of education institutions and improve the quality of higher education in general. The conclusions suggest the development trends of financing public higher education institutions of Ukraine.

    Full Text Available As a policy initiative, for-profit operation of public schools has not lived up to the claims of its proponents. An examination of issues such as teaching methods, academic achievement, autonomy, local control, and the image and influence of for-profit public schools suggests that "for-profits" are unlikely to succeed in the long term in improving the overall quality of public education. They do, however, seem capable of harming public schools.

  20. The Saccharomyces cerevisiae MLH3 gene functions in MSH3-dependent suppression of frameshift mutations

    The Saccharomyces cerevisiae genome encodes four MutL homologs. Of these, MLH1 and PMS1 are known to act in the MSH2-dependent pathway that repairs DNA mismatches. We have investigated the role of NLH3 in mismatch repair. Mutations in MLH3 increased the rate of reversion of the hom3-10 allele by increasing the rate of deletion of a single T in a run of 7 Ts. Combination of mutations in MLH3 and MSH6 caused a synergistic increase in the hom3-10 reversion rate, whereas the hom3-10 reversion rate in an mlh3 msh3 double mutant was the same as in the respective single mutants. Similar results were observed when the accumulation of mutations at frameshift hot spots in the LYS2 gene was analyzed, although mutation of MLH3 did not cause the same extent of affect at every LYS2 frameshift hot spot. MLH3 interacted with MLH1 in a two-hybrid system. These data are consistent with the idea that a proportion of the repair of specific insertion/deletion mispairs by the MSH3-dependent mismatch repair pathway uses a heterodimeric MLH1-MLH3 complex in place of the MLH1-PMS1 complex

    MLH1 is a major tumour suppressor gene involved in the pathogenesis of Lynch syndrome and various sporadic cancers. Despite their potential pathogenic importance, genomic regions capable of regulating MLH1 expression over long distances have yet to be identified. Here we use chromosome conformation capture (3C) to screen a 650-kb region flanking the MLH1 locus to identify interactions between the MLH1 promoter and distal regions in MLH1 expressing and non-expressing cells. Putative enhancers were functionally validated using luciferase reporter assays, chromatin immunoprecipitation and CRISPR-Cas9 mediated deletion of endogenous regions. To evaluate whether germline variants in the enhancer might contribute to impaired MLH1 expression in patients with suspected Lynch syndrome, we also screened germline DNA from a cohort of 74 patients with no known coding mutations or epimutations at the MLH1 promoter. A 1.8kb DNA fragment, 35kb upstream of the MLH1 transcription start site enhances MLH1 gene expression in colorectal cells. The enhancer was bound by CTCF and CRISPR-Cas9 mediated deletion of a core binding region impairs endogenous MLH1 expression. 5.4% of suspected Lynch syndrome patients have a rare single nucleotide variant (G>A; rs143969848; 2.5% in gnomAD European, non-Finnish) within a highly conserved CTCF binding motif, which disrupts enhancer activity in SW620 colorectal carcinoma cells. A CTCF bound region within the MLH1 -35 enhancer regulates MLH1 expression in colorectal cells and is worthy of scrutiny in future genetic screening strategies for suspected Lynch syndrome associated with loss of MLH1 expression.

    Germline mutations of MLH1 are responsible for tumor generation in nearly 50% of patients with Lynch Syndrome, and around 15% of sporadic colorectal cancers show MLH1-deficiency due to promotor hypermethylation. Although these tumors are of lower aggressiveness the benefit for these patients from standard chemotherapy is still under discussion. Recently, it was shown that the sensitivity to the DNA-PKcs inhibitor KU60648 is linked to loss of the MMR protein MSH3. However, loss of MSH3 is rather secondary, as a consequence of MMR-deficiency, and frequently detectable in MLH1-deficient tumors. Therefore, we examined the expression of MLH1, MSH2, MSH6, and MSH3 in different MMR-deficient and proficient cell lines and determined their sensitivity to KU60648 by analyzing cell viability and survival. MLH1-dependent ability of double strand break (DSB) repair was monitored after irradiation via γH2AX detection. A panel of 12 colon cancer cell lines, two pairs of cells, where MLH1 knock down was compared to controls with the same genetic background, and one MLH1-deficient cell line where MLH1 was overexpressed, were included. In summary, we found that MLH1 and/or MSH3-deficient cells exhibited a significantly higher sensitivity to KU60648 than MMR-proficient cells and that overexpression of MLH1 in MLH1-deficient cells resulted in a decrease of cell sensitivity. KU60648 efficiency seems to be associated with reduced DSB repair capacity. Since the molecular testing of colon tumors for MLH1 expression is a clinical standard we believe that MLH1 is a much better marker and a greater number of patients would benefit from KU60648 treatment. © 2017 Wiley Periodicals, Inc.

  3. Finding the needle in a haystack: identification of cases of Lynch syndrome with MLH1 epimutation.

    Science.gov (United States)

    Hitchins, Megan P

    2016-07-01

    Constitutional epimutation of the DNA mismatch repair gene, MLH1, represents a minor cause of Lynch syndrome. MLH1 epimutations are characterized by the soma-wide distribution of methylation of a single allele of the MLH1 promoter accompanied by constitutive allelic loss of transcription. 'Primary' MLH1 epimutations, considered pure epigenetic defects, tend to arise de novo in patients without a family history or any apparent genetic mutation. These demonstrate non-Mendelian inheritance. 'Secondary' MLH1 epimutations have a genetic basis and have been linked to non-coding genetic alterations in the vicinity of MLH1. These demonstrate autosomal dominant inheritance. Despite convincing evidence of their role in causing Lynch-type cancers, routine screening for MLH1 epimutations has not been widely adopted. Complicating factors may include: the need to perform additional methylation-based testing beyond the standard genetic screening for a germline mutation; the lack of a consensus algorithm for the selection of patients warranting MLH1 epimutation testing; overlapping molecular pathology features of MLH1 methylation and loss of MLH1 expression with more prevalent sporadic MSI cancers; the rarity of MLH1 epimutation; the variable inter-generational inheritance patterns; and the cost-effectiveness of screening. Nevertheless, a positive molecular diagnosis of MLH1 epimutation is clinically important because carriers have a high personal risk of developing metachronous Lynch-type cancers, and their relatives may also be at risk of carriage. Extending existing universal and clinic-based screening algorithms for Lynch syndrome to include an additional arm of selection criteria for cases warranting MLH1 epimutation testing could provide a cost-effective means of diagnosing these cases.

    The history of providing public information on nuclear energy in Canada for more than 40 years is described. Information centers are part of all nuclear power plants and they receive many thousands of visitors each year. Until the 1970s public information programs were relatively easy. There was a lot of interest in nuclear energy, and there was little debate about it or opposition to it. But times have changed, and Canadian public information strategies and tactics have evolved to meet challenge of answering increasing public concerns. In the past 20 years Canada has gone through three phases in relationship with the public: information, communication, participation. Activities on implementation of these phases are outlined

    MLH1 is a key DNA mismatch repair (MMR) protein involved in maintaining genomic stability by participating in the repair of endogenous and exogenous mispairs in the daughter strands during S phase. Exogenous mispairs can result following treatment with several classes of chemotherapeutic drugs, as well as with ionizing radiation. In this study, we investigated the role of the MLH1 protein in determining the cellular and molecular responses to prolonged low-dose rate ionizing radiation (LDR-IR), which is similar to the clinical use of cancer brachytherapy. An isogenic pair of MMR(+) (MLH1(+)) and MMR(-) (MLH1(-)) human colorectal cancer HCT116 cells was exposed to prolonged LDR-IR (1.3-17 cGy/h x 24-96 h). The clonogenic survival and gene mutation rates were examined. Cell cycle distribution was analyzed with flow cytometry. Changes in selected DNA damage repair proteins, DNA damage response proteins, and cell death marker proteins were examined with Western blotting. MLH1(+) HCT116 cells showed greater radiosensitivity with enhanced expression of apoptotic and autophagic markers, a reduced HPRT gene mutation rate, and more pronounced cell cycle alterations (increased late-S population and a G(2)/M arrest) following LDR-IR compared with MLH1(-) HCT116 cells. Importantly, a progressive increase in MLH1 protein levels was found in MLH1(+) cells during prolonged LDR-IR, which was temporally correlated with a progressive decrease in Rad51 protein (involved in homologous recombination) levels. MLH1 status significantly affects cellular responses to prolonged LDR-IR. MLH1 may enhance cell radiosensitivity to prolonged LDR-IR through inhibition of homologous recombination (through inhibition of Rad51).

  9. Future directions for Public Health Education reforms in India

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Health systems globally are experiencing a shortage of competent public health professionals. Public health education across developing countries is stretched by capacity generation and maintaining an adequate ‘standard’ and ‘quality’ of their graduate product. We analyzed the Indian public health education scenario using the institutional and instructional reforms framework advanced by the Lancet Commission report on Education of Health Professionals. The emergence of a new century necessitates a re-visit on the institutional and instructional challenges surrounding public health education. Currently, there is neither an accreditation council nor a formal structure or system of collaboration between academic stakeholders. Health systems have little say in health professional training with limited dialogue between health systems and public health education institutions. Despite a recognized shortfall of public health professionals, there are limited job opportunities for public health graduates within the health system and absence of a structured career pathway for them. Public health institutions need to evolve strategies to prevent faculty attrition. A structured development program in teaching-learning methods and pedagogy is the need of the hour.

    Introduction At the present time, higher education institutions dealing with education for public health in Europe and beyond are faced with a complex and comprehensive task of responding to global health challenges. Review Literature reviews in public health and global health and exploration of internet presentations of regional and global organisations dealing with education for public health were the main methods employed in the work presented in this paper. Higher academic institutions are searching for appropriate strategies in competences-based education, which will increase the global attractiveness of their academic programmes and courses for continuous professional development. Academic professionals are taking advantage of blended learning and new web technologies. In Europe and beyond they are opening up debates about the scope of public health and global health. Nevertheless, global health is bringing revitalisation of public health education, which is recognised as one of the core components by many other academic institutions involved in global health work. More than ever, higher academic institutions for public health are recognising the importance of institutional partnerships with various organisations and efficient modes of cooperation in regional and global networks. Networking in a global setting is bringing new opportunities, but also opening debates about global harmonisation of competence-based education to achieve functional knowledge, increase mobility of public health professionals, better employability and affordable performance. Conclusions As public health opportunities and threats are increasingly global, higher education institutions in Europe and in other regions have to look beyond national boundaries and participate in networks for education, research and practice.

    The CpG island methylator phenotype (CIMP) is a major molecular pathway in colorectal cancer. Approximately 25% to 60% of CIMP tumors are microsatellite unstable (MSI-H) due to DNA hypermethylation of the MLH1 gene promoter. Our aim was to determine if the distributions of clinicopathologic factors in CIMP-positive tumors with MLH1 DNA methylation differed from those in CIMP-positive tumors without DNA methylation of MLH1. We assessed the associations between age, sex, tumor-site, MSI status BRAF and KRAS mutations, and family colorectal cancer history with MLH1 methylation status in a large population-based sample of CIMP-positive colorectal cancers defined by a 5-marker panel using unconditional logistic regression to assess the odds of MLH1 methylation by study variables. Subjects with CIMP-positive tumors without MLH1 methylation were significantly younger, more likely to be male, and more likely to have distal colon or rectal primaries and the MSI-L phenotype. CIMP-positive MLH1-unmethylated tumors were significantly less likely than CIMP-positive MLH1-methylated tumors to harbor a BRAF V600E mutation and significantly more likely to harbor a KRAS mutation. MLH1 methylation was associated with significantly better overall survival (HR, 0.50; 95% confidence interval, 0.31-0.82). These data suggest that MLH1 methylation in CIMP-positive tumors is not a completely random event and implies that there are environmental or genetic determinants that modify the probability that MLH1 will become methylated during CIMP pathogenesis. MLH1 DNA methylation status should be taken into account in etiologic studies. ©2015 American Association for Cancer Research.

    Aberrant DNA methylation is a common molecular feature in human cancer. The aims of this study were to analyze the methylation status of MLH1, one of the DNA mismatch repair (MMR) genes, in human colorectal and lung cancer and to evaluate its clinical relevance. The expression of MLH1 was analyzed in 8 colorectal cancer (CRC) and 8 lung cancer cell lines by real-time RT-PCR and western blotting. The MLH1 protein expression was evaluated by immunohistochemistry on tissue microarrays including 121 primary CRC and 90 lung cancer patient samples. In cancer cell lines, the methylation status of MLH1 promoter and exon 2 was investigated by bisulfite sequencing (BS). Methylation-specific-PCR (MSP) was used to evaluate methylation status of MLH1. The expression of MLH1 mRNA was detected in 8 CRC cell lines as well as normal colonic fibroblast cells CCD-33Co. At protein levels, MLH1 was lost in one CRC cell line HCT-116 and normal cells CCD-33Co. No methylation was found in the promoter and exon 2 of MLH1 in CRC cell lines. MLH1 was expressed in 8 lung cancer cell lines at both mRNA and protein levels. Compared to cancer cells, normal bronchial epithelial cells (HBEC) had lower expression of MLH1 protein. In primary CRC, 54.5% of cases exhibited positive staining, while 47.8% of lung tumors were positive for MLH1 protein. MSP analysis showed that 58 out of 92 (63.0%) CRC and 41 out of 73 (56.2%) lung cancer exhibited MLH1 methylation. In CRC, the MLH1 methylation was significantly associated with tumor invasion in veins (P=0.012). However, no significant links were found between MLH1 expression and promoter methylation in both tumor entities. MLH1 methylation is a frequent molecular event in CRC and lung cancer patients. In CRC, methylation of MLH1 could be linked to vascular invasiveness. Copyright © 2017 Elsevier GmbH. All rights reserved.

    The DNA mismatch repair (MMR) gene MutL homolog 1 ( MLH1 ) is critical for the maintenance of genomic integrity. Methylation of the MLH1 gene promoter was identified as a prognostic marker for numerous types of cancer including glioblastoma, colorectal, ovarian and gastric cancer. The present study aimed to determine whether MLH1 promoter methylation was associated with survival in male patients with esophageal squamous cell carcinoma (ESCC). Formalin-fixed, paraffin-embedded ESCC tissues were collected from 87 male patients. MLH1 promoter methylation was assessed using the methylation-specific polymerase chain reaction approach. Kaplan-Meier survival curves and log-rank tests were used to evaluate the association between MLH1 promoter methylation and overall survival (OS) in patients with ESCC. Cox regression analysis was used to obtain crude and multivariate hazard ratios (HR), and 95% confidence intervals (CI). The present study revealed that MLH1 promoter methylation was observed in 53/87 (60.9%) of male patients with ESCC. Kaplan-Meier survival analysis demonstrated that MLH1 promoter hypermethylation was significantly associated with poorer prognosis in patients with ESCC (P=0.048). Multivariate survival analysis revealed that MLH1 promoter hypermethylation was an independent predictor of poor OS in male patients with ESCC (HR=1.716; 95% CI=1.008-2.921). Therefore, MLH1 promoter hypermethylation may be a predictor of prognosis in male patients with ESCC.

    Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to "best evidence medical education" (BEME) and second to evaluate the development of this literature toward more "best evidence" between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words "anatomy," "anatomical," or "anatomist." Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about "teaching methods" and 17% about "teaching content," 8% referred to "practical value," and 10% to "side effects" of anatomy education. Ten percent of the statements were "positional," five percent "traditional," four percent "self-evident," and two percent referred to "quality of care." Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education. Copyright © 2011 American Association of Anatomists.

    Two nuclear power stations on the coast of southern China are situated some 50 kilometers to the northeast of Hong Kong. Although the stations are far away from Hong Kong, the construction and operation of the nuclear power stations have generated public anxiety locally, in particular, after the Chernobyl accident in 1986. A comprehensive contingency plan which takes into account such concerns of the public has been implemented in Hong Kong. Cooperation by the public is vital to the effective implementation of any contingency plan. Understanding of the basics of radiation protection as well as the contingency plan will help the public to appreciate the situation and react in a rational manner. A public education program to promote awareness of the contingency plan has been implemented in Hong Kong. In particular, a Virtual Exhibition Hall on radiation has been developed and launched in February 2002 for access by the public via Internet. A video and a set of web pages will be launched in the later part of 2002 to inform and educate the public on matters related to nuclear accident response in Hong Kong. This paper describes the public education programme in Hong Kong to promote public awareness and understanding of the nuclear contingency plan

    Education about basic concepts of new technological developments should be kept abreast of the progress of the technology. The education should not be an over simplified version of the scientific or technological material but should be presented in language suitable for people who are non scientific and think more in terms of the arts where imagery and historical background form a platform for appreciation of new ideas. Energy must be a subject in the schools curriculum and a topic which is discussed and explained in the media. The most important task is to bring the reality of the nuclear cycle into clear perspective for non-scientists. Children should have it explained at an early age and for them illustrations and 'hands on experience' are necessary. The impact on the society and the environment should be clearly and factually assessed and presented. International co-operation in maintaining the availability of such material is also valuable. Some examples of such educational material prepared in the United Kingdom are presented. 1 app. (I.P.)

    Epidemiological data demonstrated that hormone replace treatment has protective effect against colorectal cancer (CRC). Our previous studies showed that this effect may be associated with DNA mismatch repair. This study aims to investigate the mechanism of estrogen induction of MLH1, and whether colorectal tumor proliferation can be inhibited through induction of MLH1 by estrogen signal pathway. Human CRC cell lines were used to examine the regulation of MLH1 expression by over-expression and depletion of estrogen receptor-α (ERα) and estrogen receptor-β (ERβ), under the treatment with 17β-estradiol or β-Estradiol 6-(O-carboxy-methyl)oxime:BSA, followed by a real-time Q-PCR and Western blotting analysis. Luciferase reporter and chromatin immunoprecipitation assays were used to identify the estrogen response elements in the proximal promoter of MLH1 gene. Then, the influence of estrogen-induced MLH1 on CRC tumor growth were determined in vitro and in vivo. We found that mismatch repair ability and microsatellite stability of cells were enhanced by estrogen via induction of MLH1 expression, which was mediated by ERβ, through a transcriptional activation process. Furthermore, we identified that ERβ exerted an inhibitory effect on CRC tumor proliferation in vitro and in vivo, combined with 5-FU, through up-regulation of MLH1 expression. Finally, we concluded that estrogen enhances mismatch repair ability and tumor inhibition effect in vitro and in vivo, via induction of MLH1 expression mediated by ERβ.

    The DNA repair machinery plays a key role in maintaining genomic stability by preventing the emergence of mutations. Furthermore, the -93G>A polymorphism in the MLH1 gene has been associated with an increased risk of developing colorectal cancer. Therefore, the aim of this study was to examine the expression pattern and effect of this polymorphism in normal and tumour samples from patients with colorectal cancer. The MLH1 -93G>A (rs1800734) polymorphism was detected by PCR-RFLP in 49 cases of colorectal cancer. MLH1 expression was investigated using real-time quantitative PCR. The results indicate a significant decrease in MLH1 expression in tumour samples compared to their normal counterparts. The MLH1 gene was also significantly repressed in samples from patients who had some degree of tumour invasion into other organs. Similarly, those patients who were in a more advanced tumour stage (TNM III and IV) exhibited a significant reduction in MLH1 gene expression. Finally, the mutant genotype AA of MLH1 was associated with a significant decrease in the expression of this gene. This finding suggests that this polymorphism could increase the risk of developing colorectal cancer by a defective mismatch repair system, particularly through the loss of MLH1 expression in an allele-specific manner.

    ANDRILL field projects during the IPY included the McMurdo Ice Shelf (MIS) and Southern McMurdo Sound (SMS) drilling projects, and the Mackay Sea Valley (MSV) and Offshore New Harbor (ONH) seismic surveys. ANDRILL's international network of scientists, engineers, students and educators work together to convey an understanding of geoscience research and the process of science to non-technical audiences. ANDRILL education and public outreach (EPO) program goals are to: (1) promote environmental and polar science literacy for all audiences; (2) develop and disseminate engaging resources for formal and informal education; (3) develop and nurture a network of polar science educators; (4) spark the curiosity of students and the general public; (5) encourage students to pursue careers in science; (6) challenge misconceptions about scientific research; (7) provide professional development opportunities for educators; and, (8) encourage inquiry teaching in science education. During the IPY, ANDRILL established partnerships with several IPY projects to enhance science literacy and promote the IPY in formal and informal education and outreach venues. ANDRILL-led initiatives include the ARISE (ANDRILL Research Immersion for Science Educators) Program, Project Iceberg, the FLEXHIBIT (FLEXible exHIBIT; in partnership with Antarctica’s Climate Secrets/IPY Engaging Antarctica), and the Project Circle. ANDRILL partnerships developed with several museums and school districts for teacher professional development workshops and a variety of public events. A polar learning community was created from the ARISE participants and their many contacts, the Project Circle participants, and interested educators who contacted ANDRILL. EPO activities are continuing in the post-IPY period with additional funding. The ARISE program has been successful in building a team of educators and a network of international collaborations across grade levels and cultures. The ANDRILL website has expanded to

Mismatch repair prevents the accumulation of erroneous insertions/deletions and non-Watson–Crick base pairs in the genome. Pathogenic mutations in the MLH1 gene are associated with a predisposition to Lynch and Turcot’s syndromes. Although genetic testing for these mutations is available, robust classification of variants requires strong clinical and functional support. Here, the first structure of the N-terminus of human MLH1, determined by X-ray crystallography, is described. The structure shares a high degree of similarity with previously determined prokaryotic MLH1 homologs; however, this structure affords a more accurate platform for the classification of MLH1 variants

    Full Text Available Education exchanges are a key element of public diplomacy for most countries that considered effective in that domain of foreign policy activities. Education exchanges are attributed an important role in the post-war peace settlement between Germany and France and in determining the outcome of the Cold war. Relevant aspects of public diplomacy remain key elements of foreign policy instruments of the US, Germany and many other countries. Russia has been increasingly active in public diplomacy in the past decade and the role of education exchanges has been increasing which is also demonstrated by a growing number of expert publications on the subject. However the strategy, the quality of organization and the use of modern technologies remain at a relatively low level which leads to an inefficient use of resources. Priority issues that can be a core of Russia's public diplomacy (and foreign policy in general. Moreover, systemic work would be required to evaluate efficiency of current and complete projects which would allow determine effectiveness of programs and appropriateness of resources used. Education exchanges need to be targeted at both bringing international students to Russia and assisting Russian students to study internationally and professors to teach abroad. Finally, international best practices show that there is a need to maintain connections with international exchanges alumni and assist them to maintain connections with each other including with the use of modern technologies.

  5. The cost-effectiveness of public postsecondary education subsidies.

    2001-02-01

    Although educational attainment is a well-recognized covariate of health status, it is rarely thought of as a tool to be used to improve health. Since fewer than 40% of U.S. citizens have a college degree, it may be possible for the government to improve the health status of the population by assuming a larger burden of the cost of postsecondary education. This paper examines the costs and health effects of a government subsidy for public postsecondary education institutions. All high school graduates in 1997 were included in a decision analysis model as a hypothetical cohort. Data from the U.S. Department of Education, the World Health Organization, and the National Center for Health Statistics were used as model inputs. Results. Relative to the present educational system, a federal subsidy for public and private colleges equal to the amount now paid by students for tuition and living expenses would save $6,176 and avert 0.0018 of a disability-adjusted life-year (DALY) per person annually if enrollment increased 5%. The overall savings among 1997 high school graduates would be $17.1 billion and 4,992 DALYs would be averted per year relative to the present educational system. If enrollment increased by just 3%, $3,743 would be saved and 0.0011 DALYs would be averted per person. An enrollment increase of 7% would lead to savings of $8,610 and 0.0025 DALYs would be averted per person relative to the present educational system. If the government were to offer a full subsidy for college tuition at public universities, both lives and money would be saved, so long as enrollment levels increased. Providing a free postsecondary education for students attending public schools may be more cost-effective than most health investments. Copyright 2001 American Health Foundation and Academic Press.

    Full Text Available To describe the frequency of MLH1 promoter methylation in colorectal cancer (CRC; to explore the associations between MLH1 promoter methylation and clinicopathological and molecular factors using a systematic review and meta-analysis.A literature search of the PubMed and Embase databases was conducted to identify relevant articles published up to September 7, 2012 that described the frequency of MLH1 promoter methylation or its associations with clinicopathological and molecular factors in CRC. The pooled frequency, odds ratio (OR and 95% confidence intervals (95% CI were calculated.The pooled frequency of MLH1 promoter methylation in unselected CRC was 20.3% (95% CI: 16.8-24.1%. They were 18.7% (95% CI: 14.7-23.6% and 16.4% (95% CI: 11.9-22.0% in sporadic and Lynch syndrome (LS CRC, respectively. Significant associations were observed between MLH1 promoter methylation and gender (pooled OR = 1.641, 95% CI: 1.215-2.215; P = 0.001, tumor location (pooled OR = 3.804, 95% CI: 2.715-5.329; P<0.001, tumor differentiation (pooled OR = 2.131, 95% CI: 1.464-3.102; P<0.001, MSI (OR: 27.096, 95% CI: 13.717-53.526; P<0.001. Significant associations were also observed between MLH1 promoter methylation and MLH1 protein expression, BRAF mutation (OR = 14.919 (95% CI: 6.427-34.631; P<0.001 and 9.419 (95% CI: 2.613-33.953; P = 0.001, respectively.The frequency of MLH1 promoter methylation in unselected CRC was 20.3%. They were 18.7% in sporadic CRC and 16.4% in LS CRC, respectively. MLH1 promoter methylation may be significantly associated with gender, tumor location, tumor differentiation, MSI, MLH1 protein expression, and BRAF mutation.

    How do we reach the public with the exciting story of Solar System Exploration? How do we encourage girls to think about careers in science, math, engineering and technology? Why should NASA scientists make an effort to reach the public and informal education settings to tell the Solar System Exploration story? These are questions that the Solar System Exploration Forum, a part of the NASA Office of Space Science Education (SSE) and Public Outreach network, has tackled over the past few years. The SSE Forum is a group of education teams and scientists who work to share the excitement of solar system exploration with colleagues, formal educators, and informal educators like museums and youth groups. One major area of the SSE Forum outreach supports the training of Girl Scouts of the USA (GS) leaders and trainers in a suite of activities that reflect NASA missions and science research. Youth groups like Girl Scouts structure their activities as informal education.

    We are going towards a globalized world, this involving the integration of every activity and every person. The public involvement in the development process is evident, taking into account that any objective will affect the people and the negative feedback could influence the result of the investment. Generally the public could be influenced by amplification of negative evaluated consequences, resulting psychosocial effects leading to illness or anxieties. This problem will be resolved by the public access to information provided by experts. A real-time interactive communication system is proposed as an open tool in order to facilitate decision-making by access to rapid and reliable information. The main task of the system is to collect, process, display and exchange the information relative to environmental impact assessment (EIA), to provide assistance, to receive specific opinions, being also proposed for public understanding of the field. The education and training integration will mitigate the barriers, which may inhibit the interaction and communication process. To increase learning will assure specialists-public interaction and a good information flow for knowledge exchange. The paper will outline key approaches in reaching agreement on the people educational process importance. The impact of development will be available to the public revealing the positive consequences, such as increased employment and income. An effective way to avoid negative reactions consists of the extensive consultation to identify the concerns and needs of the public, the access to suggestive and attractive programs for education and training. The system is developed as a modern information module, integrated into complex international management systems. It can be placed everywhere, everybody could access the facilities for education, world experience and training. Providing a real-time response to citizen concerns, the system represents an economic and rapid way to mitigate the

    One of the most difficult barriers to overcome in the task of gaining greater public acceptance of nuclear power is the widespread lack of correct information about the true risks and benefits of nuclear energy. The news media are the most prevalent sources of information for the public but they are highly constrained by the limits of space, time, and reader/viewer interest span in being able to cover this complex subject with any degree of completeness, much less with any degree of accuracy. Another source of information for the general public is the educational system, and while it also has its limitations, they are somewhat different from those faced by the media, and the educational system is generally considered to be a more credible information source than the media. This paper report on three programs undertaken in 1985 and 1986 by the Virginia Section of the American Nuclear Society (ANS) in conjunction with the University of Virginia (UVA), the Virginia State Department of Education, and various nuclear industry participants. Each program had its unique features, successes, an failures. All-in-all, these programs have been reported as being quite successful in helping to reach the public through informing the educators

    2014-02-01

    Full Text Available The interest of this paper is based on presenting the importance of educational instruction today, in general and in particular the accounting career. This, it should be noted, is part of the development trends of cognitive skills, instrumental skills and values that a person must acquire during the education period at a higher educational institution, which will allow the graduate to be competent to begin the professional practice.The complexity that is involved in the public accountant career in both their education based on international standards like the attributes to be displayed in the quality of performance, has forced higher education experts to guide newways of undertaking the education strategy. This is accomplished through the adoption of models consistent with the demands of society and the employment market. Of these, competencies education is one of the models that best contribute to the learning process, allowing at the potential accounting professional to develop skills, abilities and attitudes needed to join into the labor market successfully. In this sense, the college, university, or an academic unit faculty, school, program - they decided to adopt, provide and ensure competencies education, mustdo according to the guidelines proposed for teaching methodologies, social responsibility and the business world. Similarly, should be based on participatory action committed by students and teachers, and the respect for human values. Within this scheme, it must prioritize the humanistic education of the person in their professional projection.

    2016-09-01

    We sought to evaluate the caliber of education mainstream media provides the public about brain death. We reviewed articles published prior to July 31, 2015, on the most shared/heavily trafficked mainstream media websites of 2014 using the names of patients from two highly publicized brain death cases, "Jahi McMath" and "Marlise Muñoz." We reviewed 208 unique articles. The subject was referred to as being "alive" or on "life support" in 72% (149) of the articles, 97% (144) of which also described the subject as being brain dead. A definition of brain death was provided in 4% (9) of the articles. Only 7% (14) of the articles noted that organ support should be discontinued after brain death declaration unless a family has agreed to organ donation. Reference was made to well-known cases of patients in persistent vegetative states in 16% (34) of articles and 47% (16) of these implied both patients were in the same clinical state. Mainstream media provides poor education to the public on brain death. Because public understanding of brain death impacts organ and tissue donation, it is important for physicians, organ procurement organizations, and transplant coordinators to improve public education on this topic. © 2016 John Wiley & Sons A/S.

  6. The corruption bogey in South Africa: Is public education safe?

    Directory of Open Access Journals (Sweden)

    Erika Serfontein

    2015-02-01

    Full Text Available Corruption is a constant global phenomenon, which is becoming more complex and intense as competition for resources increases. It is even more so amongst those living in developing countries, particularly emerging economies such as South Africa. Acts of corruption directly contest the basic principles of South Africa's Constitution, which aims at establishing freedom and security for everyone and a democracy 'for the people, by the people'. The aim of this article is to determine whether South African public education is safe from the corruption 'bogey', where reflection is made on professional public school management, which is the responsibility of school principals. Our objectives include designing an education-specific definition of corruption to advance accountable and transparent leadership; establishing the degree to which corruption has infiltrated the public education sphere; and making recommendations to fight corruption in public schools at professional public school management level. Among other findings, we found that even though some principals actively advocate upholding high morals, their conduct proves differently.

    1986-01-01

    The complexities of our political and legal systems, along with both insufficient information and misinformation, has resulted in significant problems in the disposal of radioactive waste. Distrust of the industry and regulators by the public, along with insufficient understanding of public fear by those responsible for waste disposal, has created a delay which shows few signs of early resolution. In light of these problems, this paper will specifically cover low-level radioactive waste disposal and management issues in the Appalachian Compact state of Pennsylvania. It will focus on the public's perception of waste technologies, and related policy issues, and the necessity of research and public education to create a bridge of understanding between those responsible for disposing of this material, those who benefit (the general public) from the creation of the waste, and those who are asked to live near disposal sites

    Single nucleotide polymorphisms (SNPs) in mismatch repair genes, especially in the MLH1 gene, are closely associated with susceptibility to hereditary nonpolyposis colorectal cancer. However, few relevant findings are available regarding the association between sporadic colorectal cancer (SCRC) and SNPs of MLH1 in Chinese patients. Therefore, the present study aimed to describe the pathogenic association between three important MLH1 polymorphisms and SCRC in the Chinese population. Peripheral blood samples from 156 SCRC patients and 311 healthy controls were collected. DNA was purified from peripheral blood, and the V384D, R217C, and I219V polymorphisms were evaluated using high-resolution melting analysis and direct sequencing. The association between the three important MLH1 polymorphisms and clinical pathological features of the SCRC patients was analyzed. In addition, PMS2-MLH1 protein interactions were determined by co-immunoprecipitation (Co-IP) to determine the protein functional alteration induced by these SNPs. Among the three polymorphisms, V384D was significantly associated with the risk of SCRC (OR = 31.36, P MLH1 R217C, V384D, and I219V variants had relative binding abilities with PMS2 of 0.59, 0.70, and 0.80, respectively, compared with the wild-type. These findings suggest that MLH1 V384D could be a promising genetic marker for susceptibility to SCRC.

    The mutL homolog-1 ( MLH1 ) is a DNA mismatch repair gene and has been reported to be frequently methylated in numerous cancers. However, the association between MLH1 methylation and esophageal cancer (EC), as well as its clinical significance, remains unclear. Hence, we conducted a systematic meta-analysis based on 19 articles (including 1384 ECs, 345 premalignant lesions, and 1244 healthy controls). Our analysis revealed that the frequency of MLH1 methylation was significantly elevated during EC carcinogenesis. In addition, we observed that MLH1 promoter methylation was associated with age (odds ratio [OR]=1.79; 95% CI =1.20-2.66), advanced tumor grade (OR=3.7; 95% CI =2.37-5.77), lymph node metastasis (OR=2.65; 95% CI =1.81-3.88), distant metastasis (OR=7.60; 95% CI =1.23-47.19), advanced clinical stage (OR=4.46; 95% CI =2.88-6.91), and poor prognosis in EC patients (hazard ratio =1.64, 95% CI =1.00-2.69). The pooled sensitivity, specificity, and area under the curve of MLH1 methylation in EC patients versus healthy individuals were 0.15, 0.99, and 0.77, respectively. Our findings indicate that MLH1 methylation is involved in the carcinogenesis, progression, and metastasis of EC. Moreover, methylated MLH1 could be a potential diagnostic and prognostic biomarker for EC.

    Mismatch repair-deficient (dMMR) colorectal cancer (CRC) is caused by Lynch syndrome (LS) in 3% and sporadic inactivation of MLH1 by hypermethylation (MLH1-hm) in 12% of cases. It is not clear whether outcomes between LS-associated and MLH1-hm CRC differ. The objective of this study was to explore differences in clinical factors and outcomes in these two groups. Patients with dMMR CRC identified by immunohistochemistry staining and treated at a single institution from 1998 to 2012 were included. MLH1-hm was established with BRAF mutational analysis or hypermethylation testing. Patients' charts were accessed for information on pathology, germ-line MMR mutation testing, and clinical course. A total of 143 patients had CRC associated with LS (37 patients, 26%) or MLH1-hm (106 patients, 74%). Patients with LS were younger, more often male, presented more often with stage III disease, and had more metachronous disease than patients with MLH1-hm tumors. There was no difference in cancer-specific survival (CSS) between the groups; overall survival was longer in patients with LS, but this difference was minimal after adjusting for age and stage at diagnosis. CSS did not differ in LS-associated CRC compared with MLH1-hm CRC, suggesting that they carry a similar prognosis.Genet Med 18 9, 863-868.

    In this study, we investigated microsatellite instability in urothelial carcinoma of the renal pelvis by lack of immunohistochemical staining for MLH1 and MSH2. The study included 44 cases of urothelial carcinoma of the renal pelvis obtained from radical nephroureterectomy specimens at our institution. We evaluated the loss of nuclear immunohistochemical staining of MLH1 and MSH2. Eight of 44 (18 %) patients had negative MLH1 expression and 25/44 (57 %) patients had negative MSH2 expression. Six of 8 (75 %) patients with negative MLH1 expression were male and 2/8 (25 %) patients were female. Nineteen of 25 (75 %) patients with negative MSH2 expression were male, and 6/25 (24 %) patients were female. Seven of 8 (88 %) cases with negative MLH1 expression were high-grade urothelial carcinoma, and 21/25 (84 %) cases with negative MSH2 expression were high-grade urothelial carcinoma. Twenty-one of 44 (48 %) cases had an inverted growth pattern, of which 3/21 (14 %) cases had negative MLH1 expression and 14/21 (67 %) cases had negative MSH2 expression. Our study showed that microsatellite instability based on negative expression of MLH1 and MSH2 was more common in male patients with high-grade urothelial carcinoma. There is a strong correlation between inverted growth pattern and negative MSH2 expression. Microsatellite instability testing should be performed in patients with upper urinary tract carcinoma and may have prognostic value.

    To elucidate the role of the mismatch repair gene Mlh1 in genome instability during the fetal stage, spontaneous mutations were studied in Mlh1-deficient lacZ-transgenic mouse fetuses. Mutation levels were high at 9.5 days post coitum (dpc) and gradually increased during the embryonic stage, after which they remained unchanged. In addition, mutations that were found in brain, liver, spleen, small intestine and thymus showed similar levels and no statistically significant difference was found. The molecular nature of mutations at 12.5 dpc in fetuses of Mlh1 +/+ and Mlh1 -/- mice showed their own unique spectra, suggesting that deletion mutations were the main causes in the deficiency of the Mlh1 gene. Of note, fetuses of irradiated mice exhibited marked differences such as post-implantation loss and Mendelian distribution. Collectively, these results strongly suggest that high mutation ofMlh1 -/- -deficient fetuses has little effect on the fetuses during their early developmental stages, whereas Mlh1 -/- -deficient fetuses from X-ray irradiated mothers are clearly effected.

  15. AMERICAN AND ITALIAN PERSPECTIVES ON PUBLIC AND PRIVATE EDUCATION CHOICES

    2011-07-01

    Full Text Available This work is based on the analysis of the public and private support to education and human capital development in two specific national contexts: the U.S. and Italy. Recent researches have firmly demonstrated the value of higher levels of education for socio-economic development, poverty reduction, higher incomes, employment and eliminating child labour, gender equality. The increased competition and globalization of economic activity, acceleration in technological and scientific knowledge, information revolution and more recently the worldwide economic recession continue to raise the value of education and training in preparing individuals for future employment, upgrading skills for greater workplace mobility, and underpinning wealth creation and economic development through human capital formation. The International Labour Organization (2010 has pointed out the key role played by higher levels of education and skills training in employment and social protection policies. In the Western world, the education industry is complex and diverse. It combines a dominant public sector of schools and universities and community colleges which educate the majority of students; a varied private sector mainly consists of nonprofit organizations that encompass some of the world's most elite education and scientific institutes. The importance of education for economic growth and development is well documented from a historical and economic standpoints. In this research we examine some evolving relationships between the marketplace, the state, and education institutions, knowing that the context of these relations has evolved strikingly in recent years, which have seen three major developments: a growing system differentiation, changing governance patterns, and a diminished direct involvement of governments in the funding and provision of education. Therefore, we are interested in understanding on one hand the possible evolution of the studied phenomenon, and

    Previous studies reported the reconstitution of an Mlh1-Pms1-independent 5′ nick-directed mismatch repair (MMR) reaction using Saccharomyces cerevisiae proteins. Here we describe the reconstitution of a mispair-dependent Mlh1-Pms1 endonuclease activation reaction requiring Msh2-Msh6 (or Msh2-Msh3), proliferating cell nuclear antigen (PCNA), and replication factor C (RFC) and a reconstituted Mlh1-Pms1-dependent 3′ nick-directed MMR reaction requiring Msh2-Msh6 (or Msh2-Msh3), exonuclease 1 (Exo1), replication protein A (RPA), RFC, PCNA, and DNA polymerase δ. Both reactions required Mg2+ and Mn2+ for optimal activity. The MMR reaction also required two reaction stages in which the first stage required incubation of Mlh1-Pms1 with substrate DNA, with or without Msh2-Msh6 (or Msh2-Msh3), PCNA, and RFC but did not require nicking of the substrate, followed by a second stage in which other proteins were added. Analysis of different mutant proteins demonstrated that both reactions required a functional Mlh1-Pms1 endonuclease active site, as well as mispair recognition and Mlh1-Pms1 recruitment by Msh2-Msh6 but not sliding clamp formation. Mutant Mlh1-Pms1 and PCNA proteins that were defective for Exo1-independent but not Exo1-dependent MMR in vivo were partially defective in the Mlh1-Pms1 endonuclease and MMR reactions, suggesting that both reactions reflect the activation of Mlh1-Pms1 seen in Exo1-independent MMR in vivo. The availability of this reconstituted MMR reaction should now make it possible to better study both Exo1-independent and Exo1-dependent MMR. PMID:26170454

    Lynch syndrome (LS) is an inherited predisposition cancer syndrome, typically caused by germline mutations in the mismatch repair genes MLH1, MSH2, MSH6 and PMS2. In the last years, a role for epimutations of the same genes has also been reported. MLH1 promoter methylation is a well known mechanism of somatic inactivation in tumors, and more recently, several cases of constitutional methylation have been identified. In four subjects affected by multiple tumors and belonging to a suspected LS family, we detected a novel secondary MLH1 gene epimutation. The methylation of MLH1 promoter was always linked in cis with a 997 bp-deletion (c.-168_c.116+713del), that removed exon 1 and partially involved the promoter of the same gene. Differently from cases with constitutional primary MLH1 inactivation, this secondary methylation was allele-specific and CpGs of the residual promoter region were totally methylated, leading to complete allele silencing. In the colon tumor of the proband, MLH1 and PMS2 expression was completely lost as a consequence of a pathogenic somatic point mutation (MLH1 c.199G>A, p.Gly67Arg) that also abrogated local methylation by destroying a CpG site. The evidences obtained highlight how MLH1 mutations and epimutations can reciprocally influence each other and suggest that an altered structure of the MLH1 locus results in epigenetic alteration. © The Author 2015.

    Previous studies reported the reconstitution of an Mlh1-Pms1-independent 5' nick-directed mismatch repair (MMR) reaction using Saccharomyces cerevisiae proteins. Here we describe the reconstitution of a mispair-dependent Mlh1-Pms1 endonuclease activation reaction requiring Msh2-Msh6 (or Msh2-Msh3), proliferating cell nuclear antigen (PCNA), and replication factor C (RFC) and a reconstituted Mlh1-Pms1-dependent 3' nick-directed MMR reaction requiring Msh2-Msh6 (or Msh2-Msh3), exonuclease 1 (Exo1), replication protein A (RPA), RFC, PCNA, and DNA polymerase δ. Both reactions required Mg(2+) and Mn(2+) for optimal activity. The MMR reaction also required two reaction stages in which the first stage required incubation of Mlh1-Pms1 with substrate DNA, with or without Msh2-Msh6 (or Msh2-Msh3), PCNA, and RFC but did not require nicking of the substrate, followed by a second stage in which other proteins were added. Analysis of different mutant proteins demonstrated that both reactions required a functional Mlh1-Pms1 endonuclease active site, as well as mispair recognition and Mlh1-Pms1 recruitment by Msh2-Msh6 but not sliding clamp formation. Mutant Mlh1-Pms1 and PCNA proteins that were defective for Exo1-independent but not Exo1-dependent MMR in vivo were partially defective in the Mlh1-Pms1 endonuclease and MMR reactions, suggesting that both reactions reflect the activation of Mlh1-Pms1 seen in Exo1-independent MMR in vivo. The availability of this reconstituted MMR reaction should now make it possible to better study both Exo1-independent and Exo1-dependent MMR. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

The poster will share what we have learned about successful partnerships. One portion of the program is focused on providing training and NASA content and resources to K-12 educators. Teacher workshops are performed in several locations per year, including LPI and the Harris County Department of Education, as well as across the country in cooperation with other programs and NASA Planetary Science missions. To serve the public, LPI holds several public events per year called Sky Fest, featuring activities for children, telescopes for night sky viewing, and a short scientist lecture. For Sky Fest, LPI partners with the NASA Johnson Space Center Astronomical Society; they provide the telescopes and interact with members of the public as they are viewing celestial objects. International Observe the Moon Night (InOMN) is held annually and involves the same aspects as Sky Fest, but also includes partners from Johnson Space Center's Astromaterials Research and Exploration Science group, who provide Apollo samples for the event. Another audience that LPI E/PO serves is the NASA Planetary Science E/PO community. Partnering efforts for the E/PO community include providing subject matter experts for professional development workshops and webinars, connections to groups that work with diverse and underserved audiences, and avenues to collaborate with groups such as the National Park Service and the Afterschool Alliance.

    Full Text Available Due to increasing national diversity, programs addressing cultural competence have multiplied in U.S. medical training institutions. Little progress has been made to translate cultural competency training from the clinical setting into the public health setting where the focus is on population-based health, preventative programming, and epidemiological and behavioral research. The need for culturally relevant public health programming and culturally sensitive public health research is more critical than ever. Awareness of differing cultural roles needs to be included in all processes of planning, implementation and evaluation. In focusing on community-based health program planning and research, cultural competence implies that it is possible for public health professionals to completely know another culture, whereas intercultural competence implies it is a dual-sided process. Public health professionals need a commitment toward intercultural competence and skills that demonstrate flexibility, openness and self-reflection so that cultural learning is possible. In this article, the authors recommend a number of elements to develop, adapt and strengthen intercultural competence education in public health educational institutions.

    Due to increasing national diversity, programs addressing cultural competence have multiplied in U.S. medical training institutions. Although these programs share common goals for improving clinical care for patients and reducing health disparities, there is little standardization across programs.

    Continuing education (CE) is a vital component in strengthening the public health work force, and its importance has been emphasized by the Institute of Medicine and the Council for Education in Public Health. A CE preference survey was undertaken of alumni of the University of California, Berkeley, School of Public Health (UCB-SPH). Questionnaires were mailed to a one-third random sample of 1,500 graduates from 1981-1992 who currently reside in U.S. Department of Health and Human Services (HHS) Region IX. A response rate of 57% was achieved. Results of the survey show that CE activities are highly desired among respondents. Overall, 58% of respondents prefer a half-day to one-day seminar format during regular business hours, as opposed to night classes. They prefer a traditional didactic classroom presentation that is within one hour's automobile travel. The optimal setting for CE courses would be at the University of California, Berkeley, or in-house at their institution. Subject areas of interest noted by respondents are health policy development, communication in public health, community involvement, and research. Schools of public health may respond to the CE needs of their alumni through a variety of channels, including the mainstreaming of CE as part of a school's teaching responsibility, special seminars or institutes, extension courses through the larger university system, distance-based learning, and through a separately funded for-profit CE activity.

    Currently, uveal melanoma is not considered within the Lynch syndrome tumor spectrum. However, there are studies suggesting a contribution of microsatellite instability in sporadic uveal melanoma tumorigenesis. We report a 45-year-old woman who was referred for genetic counseling due to a family history of Lynch syndrome caused by a MLH1 mutation. She originally underwent enucleation of the right eye secondary to a uveal spindle cell melanoma diagnosed at age 25. The tumor recurred 22 years later presenting as an ovarian metastasis and concurrently a microscopic endometrial endometrioid carcinoma, grade 1/3 was diagnosed. Subsequent studies highlighted that the uveal melanoma showed high microsatellite instability and loss of MLH1 and PMS2 protein expression, with no MLH1 promoter methylation or BRAF mutation. Additionally, a GNAQ mutation was found. We conclude that our patient's uveal melanoma is most likely related to MLH1 germline mutation and thus Lynch syndrome related. To the best of our knowledge, this is the first report of uveal melanoma showing MLH1/PMS2 protein loss in the context of Lynch syndrome.

  10. FINANCING PUBLIC INSTITUTIONS OF ACADEMIC EDUCATION IN SPAIN

    2015-04-01

    Full Text Available Currently, Spanish universities meet the educational needs of the students with a wide offer of courses and the opportunity to study at all levels. They appear as an attractive option in the context of the relatively low cost of living compared to other countries in the EU area and under conditions of a tax system controlled by the Government. Starting from the assumption that the financing model of the academic education public institutions represents the foundation of their modernization in the current society based on changes and evolution, in this paper we propose to bring into the light of the concerns of those who are interested, through a persuasive exhibit, the Spanish model and its specific features. To this end, our debate will begin with a description of the Spanish system of academic education under the decentralized model of financing imprint, continuing with the presentation of specific skills in terms of funding on the triptych template: state - autonomous communities - universities. Subsequently, our investigative approach will focus on detailing the tertiary education financing sources: public resources, private and patrimonial revenues. The end of our presentation will be intended for conclusions, through which we aim to advance our vision regarding the investigated problems. In fact, the paper is intended to be a precursor step in carrying out a comparative study between the academic education funding mechanism in Romania and the Spanish one.

  11. Public health has no place in undergraduate medical education.

    Science.gov (United States)

    Woodward, A

    1994-12-01

    It is time to review the reasons for including public health in medical education. Undergraduate medical students are interested above all in the diagnosis and treatment of individual cases of disease; population-based health care means little to most students, and is seldom regarded as important. Should public health teachers concentrate their efforts in other areas, where students are more receptive? This paper presents arguments for and against the proposition that public health has no place in the undergraduate medical course. In favour of the proposition, it is argued that the clinical imperative is so firmly entrenched in the minds of students and in the cultures of medical schools that public health will always be diminished and elbowed to one side in medical curricula. Moreover, the major gains in the health of populations will be won in other arenas. Therefore public health should rupture the links with medical schools that were formed in another age and, in any event, are now weakening as public health strikes a new identity. The effort that currently goes into teaching unwilling medical students would have better returns if it was invested elsewhere. Against the proposition, it is argued that the health of populations will not be improved without participation of all groups with an interest in and an influence on health care. No group is more influential in the organization and delivery of health services than the medical profession, so it would be foolish for public health to withdraw from medical education. Moreover, effective medical practice requires an ability to think in terms of populations as well as individuals.(ABSTRACT TRUNCATED AT 250 WORDS)

  12. PUBLIC AND PRIVATE HIGHER EDUCATION INSTITUTIONS IN MALAYSIA: COMPETING, COMPLEMENTARY OR CROSSBREEDS AS EDUCATION PROVIDERS

    Directory of Open Access Journals (Sweden)

    Wan Chang Da

    2007-01-01

    Full Text Available Delivery of higher education used to be exclusive to the public sector in Malaysia. However, legislative changes made in 1996 led to the coexistence of public and private higher education institutions. In 2007, there were 20 public universities compared to more than 500 private institutions, of which 30 are currently categorised as universities or university colleges. Looking at their respective roles as higher education providers, public and private institutions display characteristics of being substitutes while at the same time serving complementary roles to one another. This dichotomy between public and private higher education institutions can, in fact, be seen as inclining towards a hybrid model that allows both to operate within a single system of higher education provision in the country. Such a hybrid model is evident in how the clientele is being divided between public and private higher institutions. It is also evident in the different roles played by the respective faculty members as well as in the programmes being made available in either type of institutions.

    2013-01-01

    This review positions public health as an endeavour that requires a high order of professionalism in addressing the health of populations; this requires investment in an educational capacity that is designed to meet this need. In the global context, the field has evolved enormously over the past half century, supported by institutions such as the World Bank, the World Health Organization and the Institute of Medicine. Operational structures are formulated by strategic principles, with educational and career pathways guided by competency frameworks, all requiring modulation according to local, national and global realities. Talented and well-motivated individuals are attracted by its multidisciplinary and transdisciplinary environment, and the opportunity to achieve interventions that make real differences to people's lives. The field is globally competitive and open to many professional backgrounds based on merit. Its competencies correspond with assessments of population needs, and the ways in which strategies and services are formulated. Thus, its educational planning is needs-based and evidence-driven. This review explores four public health education levels: graduate, undergraduate, continuing professional education and promotion of health literacy for general populations. The emergence of accreditation schemes is examined, focusing on their relative merits and legitimate international variations. The role of relevant research policies is recognized, along with the need to foster professional and institutional networks in all regions of the world. It is critically important for the health of populations that nations assess their public health human resource needs and develop their ability to deliver this capacity, and not depend on other countries to supply it.

    2016-07-01

    Full Text Available The tertiary education is a critic mechanism for the socio-economic progress, for individuals who aspire a brighter future and it is also considered an important catalyzer of the economic mobility (Department of Treasury and Department of Education, 2012, 2. Based on the positive role and impact that the tertiary education has on the sustainable development, President Obama once stated that it is of damage to treat education as a luxurious public service. In line with the general considerations about the tertiary education in the U.S. the parallel comparison with Albania comes as a direct interpretation of utopia in the education policy-making. As policies are usually drafted based on data and findings, in the case of Albania there is a lack of data on expenses on tertiary education as share of GDP. This stands also for the main limitation of the paper.

    Purpose To describe the frequency of MLH1 promoter methylation in colorectal cancer (CRC); to explore the associations between MLH1 promoter methylation and clinicopathological and molecular factors using a systematic review and meta-analysis. Methods A literature search of the PubMed and Embase databases was conducted to identify relevant articles published up to September 7, 2012 that described the frequency of MLH1 promoter methylation or its associations with clinicopathological and molecular factors in CRC. The pooled frequency, odds ratio (OR) and 95% confidence intervals (95% CI) were calculated. Results The pooled frequency of MLH1 promoter methylation in unselected CRC was 20.3% (95% CI: 16.8–24.1%). They were 18.7% (95% CI: 14.7–23.6%) and 16.4% (95% CI: 11.9–22.0%) in sporadic and Lynch syndrome (LS) CRC, respectively. Significant associations were observed between MLH1 promoter methylation and gender (pooled OR = 1.641, 95% CI: 1.215–2.215; P = 0.001), tumor location (pooled OR = 3.804, 95% CI: 2.715–5.329; PMLH1 promoter methylation and MLH1 protein expression, BRAF mutation (OR = 14.919 (95% CI: 6.427–34.631; PMLH1 promoter methylation in unselected CRC was 20.3%. They were 18.7% in sporadic CRC and 16.4% in LS CRC, respectively. MLH1 promoter methylation may be significantly associated with gender, tumor location, tumor differentiation, MSI, MLH1 protein expression, and BRAF mutation. PMID:23555617

    To evaluate the association between Helicobacter pylori (H. pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability (MSI). The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction (MSP-PCR) in gastric biopsy samples from uninfected or H. pylori-infected children (n = 50), from adults with chronic gastritis (n = 97) and from adults with gastric cancer (n = 92). MLH1 and MGMT mRNA expression were measured by real-time PCR and normalised to a constitutive gene (β actin). MSI analysis was performed by screening MSI markers at 4 loci (Bat-25, Bat-26, D17S250 and D2S123) with PCR; PCR products were analysed by single strand conformation polymorphism followed by silver staining. Statistical analyses were performed with either the χ(2) test with Yates continuity correction or Fisher's exact test, and statistical significance for expression analysis was assessed using an unpaired Student's t-test. Methylation was not detected in the promoter regions of MLH1 and MGMT in gastric biopsy samples from children, regardless of H. pylori infection status. The MGMT promoter was methylated in 51% of chronic gastritis adult patients and was associated with H. pylori infection (P MLH1 methylation frequencies among H. pylori-infected and non-infected chronic gastritis adult patients were 13% and 7%, respectively. We observed methylation of the MLH1 promoter (39%) and increased MSI levels (68%) in samples from gastric cancer patients in comparison to samples from H. pylori-infected adult chronic gastritis patients (P MLH1 and MGMT mRNA were significantly reduced in chronic gastritis samples that were also hypermethylated (P MLH1 methylation did not occur in earlier-stage H. pylori infections and thus might depend on the duration of infection.

    Lynch syndrome (LS) patients have DNA mismatch repair deficiency and up to 80% lifetime risk of colorectal cancer (CRC). Screening of mutation carriers reduces CRC incidence and mortality. Selection for constitutional mutation testing relies on family history (Amsterdam and Bethesda Guidelines) and tumour-derived biomarkers. Initial biomarker analysis uses mismatch repair protein immunohistochemistry and microsatellite instability. Abnormalities in either identify mismatch repair deficiency but do not differentiate sporadic epigenetic defects, due to MLH1 promoter region methylation (13% of CRCs) from LS (4% of CRCs). A diagnostic biomarker capable of making this distinction would be valuable. This study compared two biomarkers in tumours with mismatch repair deficiency; quantification of methylation of the MLH1 promoter region using a novel assay and BRAF c.1799T>A, p.(Val600Glu) mutation status in the identification of constitutional mutations. Tumour DNA was extracted (formalin fixed, paraffin embedded, FFPE tissue) and pyrosequencing used to test for MLH1 promoter methylation and presence of the BRAF c.1799T>A, p.(Val600Glu) mutation 71 CRCs from individuals with pathogenic MLH1 mutations and 73 CRCs with sporadic MLH1 loss. Specificity and sensitivity was compared. Unmethylated MLH1 promoter: sensitivity 94.4% (95% CI 86.2% to 98.4%), specificity 87.7% (95% CI 77.9% to 94.2%), Wild-type BRAF (codon 600): sensitivity 65.8% (95% CI 53.7% to 76.5%), specificity 98.6% (95% CI 92.4% to 100.0%) for the identification of those with pathogenic MLH1 mutations. Quantitative MLH1 promoter region methylation using pyrosequencing is superior to BRAF codon 600 mutation status in identifying constitutional mutations in mismatch repair deficient tumours.

  3. Educating the Public about Deep-Earth Science

    Cronin, V. S.

    2010-12-01

    The nature of Earth’s interior is an active frontier of scientific research. Much of our current understanding of sub-crustal Earth is based on knowledge acquired in the last 2-3 decades, made possible by public funding and by dense seismic arrays, satellite remote sensing, increases in computer power that enable use of enhanced numerical techniques, improved theoretical and experimental knowledge of high PT mineral physics and chemistry, and a vigorous scientific community that has been trained to take advantage of these opportunities. An essential component of science is effective communication; therefore, providing for public education about science is a responsibility of the research community. Current public understanding of Earth’s interior is meager at best. In pre-college texts and in non-technical mass media, Earth's interior is typically visualized as an onion or baseball of concentric different-colored shells along whose upper surface "crustal" plates move like packages on conveyor belts of convecting mantle. Or the crust is thought to float on a molten mantle, as in the 19th century ideas of William Lowthian Green. Misconceptions about Earth that are brought to the undergraduate classroom must be confronted frankly and replaced by current understanding based on good science. Persistent ignorance has consequences. What do we want the public to know? First, the public should understand that knowledge of Earth's interior is important, not irrelevant. The public should know that deep-Earth processes result in Earth's dynamic magnetic field. Deep-Earth processes affect how radiation from the Sun reaches Earth, consequently affecting the atmosphere, the oceans, and the viability of life on Earth. The composition and differentiated structure of Earth's interior is a result of the early accretionary history of Earth and the Earth-Moon system. The public should also know that lithospheric tectonics, with all of its consequences (dynamic topography, volcanoes

    To investigate the impact of autophagy on the low-dose hyper-radiosensitivity (HRS) of human lung adenocarcinoma cells via MLH1 regulation. Immunofluorescent staining, Western blotting, and electron microscopy were utilized to detect autophagy in A549 and H460 cells. shRNA was used to silence MLH1 expression. The levels of MLH1, mTOR, p-mTOR, BNIP3, and Beclin-1 were measured by real-time polymerase chain reaction (PCR) and Western blotting. A549 cells, which have low levels of MLH1 expression, displayed HRS/induced radioresistance (IRR). Conversely, the radiosensitivity of H460 cells, which express high levels of MLH1, conformed to the linear-quadratic (LQ) model. After down-regulating MLH1 expression, A549 cells showed increased HRS and inhibition of autophagy, whereas H460 cells exhibited HRS/IRR. The levels of mTOR, p-mTOR, and BNIP3 were reduced in cells harboring MLH1 shRNA, and the changes in the mTOR/p-mTOR ratio mirrored those in MLH1 expression. Low MLH1-expressing A549 cells may exhibit HRS. Both the mTOR/p-mTOR and BNIP3/Beclin-1 signaling pathways were found to be related to HRS, but only mTOR/p-mTOR is involved in the regulation of HRS via MLH1 and autophagy.

    This paper, based on the international research literatures on perception of risks, designs a conceptual model of public perception of nuclear power risk. In this model, it is considered that the public perception of nuclear power risk is a dynamic, complicate and closed system and is a process from subjective perception to objective risk. Based on the features of the public perception of nuclear power risk and multi-faceted dimension influences as discussed, suggestions for the public education for nuclear power acceptance are given in five aspects with indication that the public education for nuclear power acceptance plays an important role in maintaining the public perception of nuclear power risk system.

    Dawn Education and Public Outreach strives to reach diverse learners using multi-disciplinary approaches. In-depth professional development workshops in collaboration with NASA's Discovery Program, MESSENGER and Stardust-NExT missions focusing on STEM initiatives that integrate the arts have met the needs of diverse audiences and received excellent evaluations. Another collaboration on NASA ROSES grant, Small Bodies, Big Concepts, has helped bridge the learning sequence between the upper elementary and middle school, and the middle and high school Dawn curriculum modules. Leveraging the Small Bodies, Big Concepts model, educators experience diverse and developmentally appropriate NASA activities that tell the Dawn story, with teachers' pedagogical skills enriched by strategies drawn from NSTA's Designing Effective Science Instruction. Dawn mission members enrich workshops by offering science presentations to highlight events and emerging data. Teachers' awareness of the process of learning new content is heightened, and they use that experience to deepen their science teaching practice. Activities are sequenced to enhance conceptual understanding of big ideas in space science and Vesta and Ceres and the Dawn Mission 's place within that body of knowledge Other media add depth to Dawn's resources for reaching students. Instrument and ion engine interactives developed with the respective science team leads help audiences engage with the mission payload and the data each instrument collects. The Dawn Dictionary, an offering in both audio as well as written formats, makes key vocabulary accessible to a broader range of students and the interested public. Further, as Dawn E/PO has invited the public to learn about mission objectives as the mission explored asteroid Vesta, new inroads into public presentations such as the Dawn MissionCast tell the story of this extraordinary mission. Asteroid Mapper is the latest, exciting citizen science endeavor designed to invite the

    in expression between the tumor transition zone and the invasive front. Expression of hMSH2, hMLH1, and hPMS2 was screened immunohistochemically in 92 stage IV tumors and derived liver metastases. In cases with loss of mismatch repair protein expression, lymph node metastases were also examined....... Clinicopathological parameters and Ki-67 staining indexes were evaluated and compared. Four tumors displayed a complete loss of hMLH1/hPMS2 expression at the transition zone; however, three of these expressed both proteins at the invasive front and in liver and lymph node metastases. A further four were predominantly...... hMLH1/hPMS2 negative at the transition zone, but with distinct subclones of hMLH1/hPMS2-expressing cells at the transition zone. All of these tumors expressed hMLH1/hPMS2 at the invasive front and in liver metastases, with three also expressing hMLH/hPMS2 in lymph node metastases. No significant...

    At least one-third of patients meeting clinical criteria for Lynch syndrome will have no germline mutation and constitutional epimutations leading to promoter methylation of MLH1 have been identified in a subset of these patients. We report the first case of constitutional MLH1 promoter methylation associated with a colonic polyposis syndrome in a 39 year-old man with a family history of colorectal cancer (CRC) and a personal history of 21 polyps identified over 8 years as well as the development of two synchronous CRCs over 16 months who was evaluated for a hereditary cancer syndrome. Immunohistochemistry (IHC) of multiple tumors showed absent MLH1 and PMS2 expression, though germline testing with Sanger sequencing and multiplex ligation-dependent probe amplification of these mismatch repair genes (MMR) genes was negative. A next generation sequencing panel of 29 genes also failed to identify a pathogenic mutation. Hypermethylation was identified in MLH1 intron 1 in tumor specimens along with buccal cells and peripheral white blood cells, confirming the diagnosis of constitutional MLH1 promoter methylation. This case highlights that constitutional MLH1 methylation should be considered in the differential diagnosis for a polyposis syndrome if IHC staining shows absent MMR gene expression.

    2016-01-01

    In the last decade, public health (PH) has come to the frontlines in Saudi Arabia. The recent outbreak of a novel corona virus (MERS-CoV) highlighted the importance of PH services and the need for a competent PH workforce. The urgency and panic induced by infectious disease outbreaks explain the heightened interest. Decision makers' interest in public health was observed through a series of decisions, including creating a position for Deputy Minister for Public Health, changing the name of "Directorate of Primary Healthcare Centers" to "Directorate of Public Health" in all health regions and initiating a special scholarship program to prepare health administration professionals in collaboration with US-based universities. A distinguished group of PH leaders in Saudi Arabia was gathered in a structured workshop that was organized by the Al Imam Mohammad Ibn Saud Islamic University, college of medicine to discuss the current status and future needs of PH education in the Kingdom of Saudi Arabia. The workshop highlighted the need for PH education development and outlined the challenges ahead. The main challenges laid out by participants in the workshop were the development of an appropriate PH curriculum, appropriate training spots for practical placement, the development of research priorities for PH to satisfy the needs of PH programs and agencies, attracting the most qualified academic staff, the enrolment of highly motivated students and finally, the establishment of a quality assurance program to ensure the quality of PH education programs. The development of a framework for graduate competencies in PH was perceived to be a top priority. Moreover, setting a PH workforce surveillance system, building partnership between PH academic institutions and PH services providers, implementing national campaigns to explain what PH is about and illuminating the role of PH workers were also of utmost importance.

    2002-01-01

    In July 2002, the U.S. Congress approved Yucca Mountain in Nevada as the nation's first long-term geologic repository site for spent nuclear fuel and high-level radioactive waste. This major milestone for the country's high-level radioactive waste disposal program comes after more than twenty years of scientific study and intense public interaction and outreach. This paper describes public interaction and outreach challenges faced by the U.S. Department of Energy's (DOE) Yucca Mountain Project in the past and what additional communication strategies may be instituted following the July 2002 approval by the U.S. Congress to develop the site as the nation's first long-term geologic repository for spent nuclear fuel and high-level radioactive waste. The DOE public involvement activities were driven by two federal regulations--the National Environmental Policy Act (NEPA) and the Nuclear Waste Policy Act (NWPA) of 1982, as amended. The NEPA required that DOE hold public hearings at key points in the development of an Environmental Impact Statement (EIS) and the NWPA required the agency to conduct public hearings in the vicinity of the site prior to making a recommendation regarding the site's suitability. The NWPA also provided a roadmap for how DOE would interact with affected units of government, which include the state of Nevada and the counties surrounding the site. Because the Department anticipated and later received much public interest in this high-profile project, the agency decided to go beyond regulatory-required public involvement activities and created a broad-based program that implemented far-reaching public interaction and outreach tactics. Over the last two decades, DOE informed, educated, and engaged a myriad of interested local, national, and international parties using various traditional and innovative approaches. The Yucca Mountain Project's intensive public affairs initiatives were instrumental in involving the public, which in turn resulted in

    Countries in South Asian Association for Regional Cooperation (SAARC) lack enough public health workforces to address their poor public health situation. Recently, there have been efforts to develop capacity building in public health in these countries by producing competent public health workforce through public health institutes and schools. Considering the wide nature of public health, the public health education and curricula should be linked with skills, knowledge, and competencies needed for public health practice and professionalism. The 3 domains of public health practice and the 10 essential public health services provide an operational framework to explore this link between public health practice and public health education. This framework incorporates five core areas of public health education. A master degree course in public health can be structured by incorporating these core areas as basic and reinforcing one of these areas as an elective followed by a dissertation work.

    2005-12-01

    The Solar TErrestrial RElations Observatory (STEREO) is scheduled for launch in Spring 2006. STEREO will study the Sun with two spacecrafts in orbit around it and on either side of Earth. The primary science goal is to understand the nature and consequences of Coronal Mass Ejections (CMEs). Despite their importance, scientists don't fully understand the origin and evolution of CMEs, nor their structure or extent in interplanetary space. STEREO's unique 3-D images of the structure of CMEs will enable scientists to determine their fundamental nature and origin. We will discuss the Education and Public Outreach (E/PO) program for the In-situ Measurement of Particles And CME Transients (IMPACT) suite of instruments aboard the two crafts and give examples of upcoming activities, including NASA's Sun-Earth day events, which are scheduled to coincide with a total solar eclipse in March. This event offers a good opportunity to engage the public in STEREO science, because an eclipse allows one to see the solar corona from where CMEs erupt. STEREO's connection to space weather lends itself to close partnerships with the Sun-Earth Connection Education Forum (SECEF), The Exploratorium, and UC Berkeley's Center for New Music and Audio Technologies to develop informal science programs for science centers, museum visitors, and the public in general. We will also discuss our teacher workshops locally in California and also at annual conferences such as those of the National Science Teachers Association. Such workshops often focus on magnetism and its connection to CMEs and Earth's magnetic field, leading to the questions STEREO scientists hope to answer. The importance of partnerships and coordination in working in an instrument E/PO program that is part of a bigger NASA mission with many instrument suites and many PIs will be emphasized. The Education and Outreach Porgram is funded by NASA's SMD.

    Most people involved in the public arena know that people often react with fear and concern to the word {open_quotes}radiation.{close_quotes} It is also known that many of these same people readily admit they have little knowledge of the topic. As publics are facing the demands of decision making related to low level radioactive waste, discussions of high level waste challenges, and confusing information regarding what are sound data, the difficulty in conveying good, science based information to the public is increased. In examining the various groups involved in the low level radioactive waste (LLRW) discussions, it is some of the environmental activist groups with an anti-nuclear goal whose messages are heard by the general public. Why do these groups succeed and others not? This paper will provide a cursory examination of issues surrounding how people hear the radiation science message, what people want and need to know versus what the scientific literature contains and provide examples of how information is presented from the LLRW Education Program at Ohio State University.

    NASA's EPOXI mission is reusing the Deep Impact (DI) flyby spacecraft to study comets and extra-solar planets around other stars. During the Extrasolar Planetary Observations and Characterization (EPOCh) phase of the mission extrasolar planets transiting their parent stars were observed to gain further knowledge and understanding of planetary systems. Observations of Earth also allowed for characterization of Earth as an extrasolar planet. A movie of a lunar transit of the Earth created from EPOCh images and links to existing planet finding activities from other NASA missions are available on the EPOXI website. The Deep Impact Extended Investigation (DIXI) continues the Deep Impact theme of investigating comet properties and formation by observing comet Hartley 2 in November 2010. The EPOXI Education and Public Outreach (E/PO) program is both creating new materials and updating and modifying existing Deep Impact materials based on DI mission results. Comparing Comets is a new educational activity under development that will guide students in conducting analyses of comet surface features similar to those the DIXI scientists will perform after observing comet Hartley 2. A new story designed to stimulate student creativity was developed in alignment with national educational standards. EPOXI E/PO also funded Family Science Night (FSN), a program bringing together students, families, and educators for an evening at the National Air and Space Museum in Washington, DC. FSN events include time for families to explore the museum, a presentation by a space scientist, and an astronomy themed IMAX film. Nine events were held during the 2008-2009 school year with a total attendance of 3,145 (attendance since inception reached 44,732). Half of attendance is reserved for schools with high percentages of underrepresented minorities. EPOXI additionally offers a bi-monthly newsletter to keep the public, teachers, and space enthusiasts updated on current mission activities. For more

    Transits of Venus are among the rarest predictable astronomical event that humans can enjoy, and the 2012 transit will be visible by almost all the people on Earth. It is our job as educators to bring out the thrill of being able to see the tiny dot of Venus silhouetted against the solar disk even with just a simple eye-protection filter. My Website at http://www.transitofvenus.info brings together not only historical information about the five previous transits of Venus that were observed through the 20th century--1639, 1761, 1769, 1874, and 1882--but also the scientific work carried out at the 2004 transit and at recent transits of Mercury. Based on space observations of the 1999 transit of Mercury with NASA's Transition Region and Coronal Explorer (TRACE), Glenn Schneider and I provided proof of the contemporary explanation of the black-drop effect as an amalgam of instrumental point-spread and solar limb-darkening [1]. Based on observations of the changes in the total solar irradiance during the transit, we provided an analysis of this solar-system analogue to exoplanet transits [2]. High-resolution (0.5 arcsec pixels) observations of ingress and egress with TRACE during the 2004 transit provided information about the visibility of Venus's atmosphere through its refraction of sunlight, interpreted with Venus Express observations [3]. We anticipate observing the 2012 transit with groundbased facilities of the University of Hawaii at Haleakala, and of the National Solar Observatory at Sacramento Peak, and Kitt Peak, as well as with NASA and JAXA spacecraft, including Solar Dynamics Observatory, ACRIMsat, and Hinode. The Program Group on Public Education on the Occasions of Eclipses and Transits of Commission 46 on Education and Development of the International Astronomical Union, which I chair, looks forward to participating in Education and Public Outreach efforts related to the 2012 transit.

  7. The unstructured linker arms of Mlh1-Pms1 are important for interactions with DNA during mismatch repair

    Science.gov (United States)

    Plys, Aaron J.; Rogacheva, Maria V.; Greene, Eric C.; Alani, Eric

    2012-01-01

    DNA mismatch repair (MMR) models have proposed that MSH proteins identify DNA polymerase errors while interacting with the DNA replication fork. MLH proteins (primarily Mlh1-Pms1 in baker’s yeast) then survey the genome for lesion-bound MSH proteins. The resulting MSH-MLH complex formed at a DNA lesion initiates downstream steps in repair. MLH proteins act as dimers and contain long (20 – 30 nanometers) unstructured arms that connect two terminal globular domains. These arms can vary between 100 to 300 amino acids in length, are highly divergent between organisms, and are resistant to amino acid substitutions. To test the roles of the linker arms in MMR, we engineered a protease cleavage site into the Mlh1 linker arm domain of baker’s yeast Mlh1-Pms1. Cleavage of the Mlh1 linker arm in vitro resulted in a defect in Mlh1-Pms1 DNA binding activity, and in vivo proteolytic cleavage resulted in a complete defect in MMR. We then generated a series of truncation mutants bearing Mlh1 and Pms1 linker arms of varying lengths. This work revealed that MMR is greatly compromised when portions of the Mlh1 linker are removed, whereas repair is less sensitive to truncation of the Pms1 linker arm. Purified complexes containing truncations in Mlh1 and Pms1 linker arms were analyzed and found to have differential defects in DNA binding that also correlated with the ability to form a ternary complex with Msh2-Msh6 and mismatch DNA. These observations are consistent with the unstructured linker domains of MLH proteins providing distinct interactions with DNA during MMR. PMID:22659005

    Sessile serrated adenomas are the precursor polyp of approximately 20% of colorectal carcinomas. Sessile serrated adenomas with dysplasia are rarely encountered and represent an intermediate step to malignant progression, frequently associated with loss of MLH1 expression. Accurate diagnosis of these lesions is important to facilitate appropriate surveillance, particularly because progression from dysplasia to carcinoma can be rapid. The current World Health Organization classification describes two main patterns of dysplasia occurring in sessile serrated adenomas, namely, serrated and conventional. However, this may not adequately reflect the spectrum of changes seen by pathologists in routine practice. Furthermore, subtle patterns of dysplasia that are nevertheless associated with loss of MLH1 expression are not encompassed in this classification. We performed a morphological analysis of 266 sessile serrated adenomas with dysplasia with concurrent MLH1 immunohistochemistry with the aims of better defining the spectrum of dysplasia occurring in these lesions and correlating dysplasia patterns with MLH1 expression. We found that dysplasia can be divided morphologically into four major patterns, comprising minimal deviation (19%), serrated (12%), adenomatous (8%) and not otherwise specified (79%) groups. Minimal deviation dysplasia is defined by minor architectural and cytological changes that typically requires loss of MLH1 immunohistochemical expression to support the diagnosis. Serrated dysplasia and adenomatous dysplasia have distinctive histological features and are less frequently associated with loss of MLH1 expression (13 and 5%, respectively). Finally, dysplasia not otherwise specified encompasses most cases and shows a diverse range of morphological changes that do not fall into the other subgroups and are frequently associated with loss of MLH1 expression (83%). This morphological classification of sessile serrated adenomas with dysplasia may represent an

    Methylated O6-methylguanin-DNA-methytransferase (MGMT) promoter methylation is associated with survival in patients with glioblastoma. Current evidence suggests that further mismatch repair genes play a pivotal role in the tumor response to treatment. Candidate genes are MLH1, MSH2, and MSH6. Formerly, we found evidence of prognostic impact of MLH1 and MSH6 immunohistochemical expression in a small series of patients with initial glioblastoma. Two hundred and eleven patients were included who underwent macroscopically total removal of primary glioblastoma and at least one re-craniotomy for recurrence. Immunohistochemical staining was performed on paraffin-embedded specimens of initial tumors with specific antibodies against MLH1, MSH2, and MSH6. RESULTS were compared to the Ki67 proliferation index and patient survival. Additionally, fresh frozen samples from 16 paired initial and recurrent specimens were examined using real-time reverse transcription polymerase chain reaction (RT-PCR) with specific primers against MLH1, MSH2, and MSH6. RESULTS were compared to MGMT status and survival. (1) Immunohistochemical expression of MSH6 was significantly associated with the Ki67 proliferation index (PMLH1, MLH2, and MSH6 over treatment combined with lacking MGMT methylation. In another two patients, decreased MLH1, MSH2, and MSH6 expression was observed in combination with MGMT promoter methylation. Our data indicate that there may be glioblastoma patient subgroups characterized by MMR-expression changes beyond MGMT promoter methylation. The immunohistochemical expression of MLH1, MSH2, and MSH6 in initial glioblastoma is not associated with patient survival.

    Full Text Available Computer simulation, an active learning technique, is now one of the advanced pedagogical technologies. Th e use of simulation games in the educational process allows students to gain a firsthand understanding of the processes of real life. Public- administration, public-policy and political-science courses increasingly adopt simulation games in universities worldwide. Besides person-to-person simulation games, there are computer-based simulations in public-administration education. Currently in Russia the use of computer-based simulation games in Master of Public Administration (MPA curricula is quite limited. Th is paper focuses on computer- based simulation games for students of MPA programmes. Our aim was to analyze outcomes of implementing such games in MPA curricula. We have done so by (1 developing three computer-based simulation games about allocating public finances, (2 testing the games in the learning process, and (3 conducting a posttest examination to evaluate the effect of simulation games on students’ knowledge of municipal finances. Th is study was conducted in the National Research University Higher School of Economics (HSE and in the Russian Presidential Academy of National Economy and Public Administration (RANEPA during the period of September to December 2015, in Saint Petersburg, Russia. Two groups of students were randomly selected in each university and then randomly allocated either to the experimental or the control group. In control groups (n=12 in HSE, n=13 in RANEPA students had traditional lectures. In experimental groups (n=12 in HSE, n=13 in RANEPA students played three simulation games apart from traditional lectures. Th is exploratory research shows that the use of computer-based simulation games in MPA curricula can improve students’ outcomes by 38 %. In general, the experimental groups had better performances on the post-test examination (Figure 2. Students in the HSE experimental group had 27.5 % better

    Purpose: Constitutional MLH1 epimutations manifest as promoter methylation and silencing of the affected allele in normal tissues, predisposing to Lynch syndrome–associated cancers. This study investigated their frequency and inheritance. Methods: A total of 416 individuals with a colorectal cancer showing loss of MLH1 expression and without deleterious germline mutations in MLH1 were ascertained from the Colon Cancer Family Registry (C-CFR). Constitutive DNA samples were screened for MLH1 methylation in all 416 subjects and for promoter sequence changes in 357 individuals. Results: Constitutional MLH1 epimutations were identified in 16 subjects. Of these, seven (1.7%) had mono- or hemi-allelic methylation and eight had low-level methylation (2%). In one subject the epimutation was linked to the c.-27C>A promoter variant. Testing of 37 relatives from nine probands revealed paternal transmission of low-level methylation segregating with a c.+27G>A variant in one case. Five additional probands had a promoter variant without an MLH1 epimutation, with three showing diminished promoter activity in functional assays. Conclusion: Although rare, sequence changes in the regulatory region of MLH1 and aberrant methylation may alone or together predispose to the development of cancer. Screening for these changes is warranted in individuals who have a negative germline sequence screen of MLH1 and loss of MLH1 expression in their tumor. PMID:22878509

    Mlh1 is an essential factor of mismatch repair (MMR) and meiotic recombination. It interacts through its C-terminal region with MutL homologs and proteins involved in DNA repair and replication. In this study, we identified the site of yeast Mlh1 critical for the interaction with Exo1, Ntg2......, and Sgs1 proteins, designated as site S2 by reference to the Mlh1/Pms1 heterodimerization site S1. We show that site S2 is also involved in the interaction between human MLH1 and EXO1 or BLM. Binding at this site involves a common motif on Mlh1 partners that we called the MIP-box for the Mlh1 interacting...... protein box. Direct and specific interactions between yeast Mlh1 and peptides derived from Exo1, Ntg2, and Sgs1 and between human MLH1 and peptide derived from EXO1 and BLM were measured with K(d) values ranging from 8.1 to 17.4 microM. In Saccharomyces cerevisiae, a mutant of Mlh1 targeted at site S2...

    Because climate hazards present a range of potential impacts and considerations for different kinds of stakeholders, community responses to increase resilience are best considered through the inclusion of diverse, informed perspectives. The Science Center Public Forums project has created multifaceted modules to engage diverse publics in substantive deliberations around four hazards: heat waves, drought, extreme precipitation, and sea level rise. Using a suite of background materials including visualization and narrative components, each of these daylong dialogues engage varied groups of lay-participants at eight US science centers in learning about hazard vulnerabilities and tradeoffs of proposed strategies for building resilience. Participants listen to and consider the priorities and perspectives of fellow residents and stakeholders, and work together to formulate detailed resilience plans reflecting both current science and informed public values. Deliverables for the project include visualizations of hazard vulnerabilities and strategies through immersive planetarium graphics and Google Earth, stakeholder perspective narratives, and detailed background materials for each project hazard. This session will: communicate the process for developing the hazard modules with input from subject matter experts, outline the process for iterative revisions based upon findings from formative focus groups, share results generated by participants of the project's first two pilot forums, and describe plans for broader implementation. These activities and outcomes could help to increase the capacity of informal science education institutions as trusted conveners for informed community dialogue by educating residents about vulnerabilities and engaging them in critical thinking about potential policy responses to critical climate hazards while sharing usable public values and priorities with civic planners.

    Sessile serrated adenomas with BRAF mutation progress rapidly to cancer following the development of dysplasia (SSAD). Approximately 75% of SSADs methylate the mismatch repair gene MLH1, develop mismatch repair deficiency and the resultant cancers have a good prognosis. The remaining SSADs and BRAF mutant traditional serrated adenomas (TSA) develop into microsatellite stable cancers with a poor prognosis. The reason for this dichotomy is unknown. In this study, we assessed the genotypic frequency of the MLH1-93 polymorphism rs1800734 in SSADs and TSAs to determine if the uncommon variant A allele predisposes to MLH1 promoter hypermethylation. We performed genotyping for the MLH1-93 polymorphism, quantitative methylation specific PCR, and MLH1 immunohistochemistry on 124 SSAD, 128 TSA, 203 BRAF mutant CRCs and 147 control subjects with normal colonoscopy. The minor A allele was significantly associated with a dose dependent increase in methylation at the MLH1 promoter in SSADs (p = 0.022). The AA genotype was only observed in SSADs with MLH1 loss. The A allele was also overrepresented in BRAF mutant cancers with MLH1 loss. Only one of the TSAs showed loss of MLH1 and the overall genotype distribution in TSAs did not differ from controls. The MLH1-93 AA genotype is significantly associated with promoter hypermethylation and MLH1 loss in the context of SSADs. BRAF mutant microsatellite stable colorectal cancers with the AA genotype most likely arise in TSAs since the A allele does not predispose to methylation in this context.

    Full Text Available The built environment is an integral part of the infrastructure necessary for survival. The environmental sustainability of our future generations is being scrutinised by the people responsible for the higher education. The role of higher education in creating a more environmentally sustainable future is undeniable. The aim would be to train the professionals to be environmentally literate. These issues present a challenge to the educationist as well as to the students of the Built Environment, to reconcile the environmental aspects as part of the built environment. The focus of the paper is mainly on the teaching approaches specifically on the integration of environmental sustainability issues into the subjects offered. This relates to the development of the student's awareness, perceptions of environmental sustainability and to the issues at stake with the intention to set a structured inte gration of environmental sustainability, through subjects related to the various aspects of the built environment education. These issues are in congruence with the publications of the new criteria for the validation of the courses in Built Environment, which contains newly articulated demands for students to have an understanding of the natural world and of the impact of their designs on the environment as well as on the humans.

    DNA mismatch repair maintains genomic stability by correcting errors that have escaped polymerase proofreading. Defects on mismatch repair genes lead to an increased mutation rate, microsatellite instability and predisposition to human non-polyposis colorectal cancer (HNPCC). Human MutLalpha is a heterodimer formed by the interaction of MLH1 and PMS2 that coordinates a series of key events in mismatch repair. It has been proposed that nuclear import of MutLalpha may be the first regulatory step on the activation of the mismatch repair pathway. Using confocal microscopy and mismatch repair deficient cells, we have identified the sequence determinants that drive nuclear import of human MLH1, PMS2, and MutLalpha. Transient transfection of the individual proteins reveals that MLH1 has a bipartite and PMS2 has a single monopartite nuclear localization signal. Although dimerization is not required for nuclear localization, the MutLalpha heterodimer is imported more efficiently than the MLH1 or PMS2 monomers. Interestingly, the bipartite localization signal of MLH1 can direct import of MutLalpha even when PMS2 encompasses a mutated localization signal. Hence we conclude that the presence of redundant nuclear localization signals guarantees nuclear transport of MutLalpha and, consequently, efficient mismatch repair.

    Full Text Available The availability of accessible educational facilities is essential for the better rural education. However, because of the huge population, lack of resources and absence of proper policy plans; the distance between educational facilities and rural communities is mounting as time progresses. These sorts of problematic circumstances put damaging effects on education standards and become responsible for the declining literacy rate. Hence, the goal of this research is to investigate the lack of educational institutions with respect to indigenous standards. Therefore, in this study, the dearth of education institutions was determined for the one of the most deprived sub-regions of Pakistan, i.e. Badin. The data were collected through observations, questionnaire survey, and from secondary sources, like census report and other pertinent public sector documents. The outcome of this study can be taken as an input to develop policy plans, targeting the education accessibility issues of backward communities. This research could show a guiding-path to local planning agencies, as these can come-up with the policy plans to trounce the education accessibility issues from the bucolic sub-regions of developing countries

    The mammalian DNA mismatch repair (MMR) system consists of a number of proteins that play important roles in repair of base pair mismatch mutations and in maintenance of genomic integrity. A defect in this system can cause genetic instability, which can lead to carcinogenesis. For instance, a germline mutation in one of the mismatch repair proteins, especially MLH1 or MSH2, is responsible for hereditary non-polyposis colorectal cancer. These MMR proteins also play an important role in the induction of apoptosis. Accordingly, altered expression of or a defect in MLH1 or MSH2 may confer resistance to anti-cancer drugs used in chemotherapy. We hypothesized that the ability of these two MMR proteins to regulate apoptosis are interdependent. Moreover, a defect in either one may confer resistance to chemotherapy by an inability to trigger apoptosis. To this end, we studied three cell lines-SW480, LoVo, and HTC116. These cell lines were selected based on their differential expression of MLH1 and MSH2 proteins. SW480 expresses both MLH1 and MSH2; LoVo expresses only MLH1 but not MSH2; HCT116 expresses only MSH2 but not MLH1 protein. MTT assays, a measure of cytotoxicity, showed that there were different cytotoxic effects of an anti-cancer drug, etoposide, on these cell lines, effects that were correlated with the MMR status of the cells. Cells that are deficient in MLH1 protein (HCT116 cells) were resistant to the drug. Cells that express both MLH1 and MSH2 proteins (SW480 cells) showed caspase-3 cleavage, an indicator of apoptosis. Cells that lack MLH1 (HCT116 cells) did not show any caspase-3 cleavage. Expression of full-length MLH1 protein was decreased in MMR proficient (SW480) cells during apoptosis; it remained unchanged in cells that lack MSH2 (LoVo cells). The expression of MSH2 protein remained unchanged during apoptosis both in MMR proficient (SW480) and deficient (HCT116) cells. Studies on translocation of MLH1 protein from nucleus to cytosolic fraction, an

    Clinical screening criteria, such as young age of endometrial cancer diagnosis and family history of signature cancers, have traditionally been used to identify women with Lynch Syndrome, which is caused by mutation of a DNA mismatch repair gene. Immunohistochemistry and microsatellite instability analysis have evolved as important screening tools to evaluate endometrial cancer patients for Lynch Syndrome. A complicating factor is that 15-20% of sporadic endometrial cancers have immunohistochemical loss of the DNA mismatch repair protein MLH1 and high levels of microsatellite instability due to methylation of MLH1. The PCR-based MLH1 methylation assay potentially resolves this issue, yet many clinical laboratories do not perform this assay. The objective of this study was to determine if clinical and pathologic features help to distinguish sporadic endometrial carcinomas with MLH1 loss secondary to MLH1 methylation from Lynch Syndrome-associated endometrial carcinomas with MLH1 loss and absence of MLH1 methylation. Of 337 endometrial carcinomas examined, 54 had immunohistochemical loss of MLH1. 40/54 had MLH1 methylation and were designated as sporadic, while 14/54 lacked MLH1 methylation and were designated as Lynch Syndrome. Diabetes and deep myometrial invasion were associated with Lynch Syndrome; no other clinical or pathological variable distinguished the 2 groups. Combining Society of Gynecologic Oncology screening criteria with these 2 features accurately captured all Lynch Syndrome cases, but with low specificity. In summary, no single clinical/pathologic feature or screening criteria tool accurately identified all Lynch Syndrome-associated endometrial carcinomas, highlighting the importance of the MLH1 methylation assay in the clinical evaluation of these patients.

    In certain types of human cancers, transcriptional inactivation of hMLH1 by promoter hypermethylation plays a causal role in the loss of mismatch repair functions that modulate cytotoxic pathways in response to DNA-damaging agents. The aim of the present study was to investigate the role of promoter methylation of the hMLH1 gene in malignant astrocytomas. We examined the hMLH1 promoter methylation in a homogeneous cohort of patients with 41 malignant astrocytomas treated by 1-(4-amino-2-methyl-5-pyrimidinyl)methyl-3-2(2-chloroethyl)-3-nitrosourea chemotherapy in combination with radiation and interferon therapy, and assessed the correlation of such methylation with clinical outcome. hMLH1 promoter methylation was found in 6 (15%) of the 41 newly diagnosed malignant astrocytomas. Hypermethylation of the hMLH1 promoter corresponded closely with a loss of immunohistochemical staining for hMLH1 protein (P = 0.0013). Patients with hMLH1-methylated tumors displayed a greater chance of responding to adjuvant therapy as compared with those with hMLH1-unmethylated tumors (P = 0.0150). The presence of hMLH1 hypermethylation was significantly associated with a longer progression-free survival on both univariate analysis (P = 0.0340) and multivariate analysis (P = 0.0161). The present study identified hMLH1 methylation status as a predictor of the clinical response of malignant astrocytomas to chloroethylnitrosourea-based adjuvant therapy. The findings obtained suggest that determination of the methylation status of hMLH1 could provide a potential basis for designing rational chemotherapeutic strategies, as well as for predicting prognosis.

  11. Educating for Civic Engagement: Public Achievement as a Case Study

    Costello, Bernadette Christine

    Over the last four decades there is evidence that citizens are less civically engaged, have less trust in each other and governmental institutions, and are less prepared to participate in deliberative and civic processes. This research studies the importance of acquiring deliberative and civic skills and behaviors as an integral part of civic engagement and developing educational and learning strategies to impart those skills and behaviors in an educational environment. This research uses a civic action program called Public Achievement (PA) as a case study to investigate if participating in a civic and deliberative focused program enables participants to continue to use the skills and behaviors learned in PA in non-PA activities. The research study was focused by a literature review of philosophical frameworks, educational history in the United States, and educational theory. The literature review and examples of learning civic skills and behaviors in secondary and higher educational institutions are examined to frame the analysis of PA. Based on the literature review and the design of PA, constructs and a survey instrument were developed to test the hypothesis that students who participate in PA will be more likely to exhibit civic skills and behaviors than students who did not participate in PA. The research was conducted with two schools in rural Missouri, two schools in Minneapolis, Minnesota, and two schools in St. Paul, Minnesota. The study results show that students who participated in PA were not more likely to exhibit civic skills and behaviors, and in many cases, non-PA students exhibited civic skills and behaviors more often. The findings revealed that there are programmatic, organizational, and societal barriers that may impede the effectiveness of PA. The findings suggest that implementation of civic engagement programs may be more effective when the effort is supported and reinforced by and across all parts of the organization, organizational

    The total solar eclipse of 2017 was a high-profile opportunity for nationwide public education. Astronomy experts suddenly became vital sources of information for a lay population whose interest in the eclipse greatly surpassed expectations. At the National Air and Space Museum, we leveraged our relatively accessible location and particularly diverse audience to help thousands of people, from novices to enthusiasts, prepare to view the eclipse safely. The goal was to empower all people so they could experience this unique astronomical event, understand what was happening, and observe the Sun safely. Over the course of two years spent talking with the public about the eclipse, we encountered common misconceptions, worries about safety or liability, and people experiencing confusion or information overload. We developed guidelines for handling these challenges, from correcting misinformation to managing the sudden spike in demand for glasses just before August 21.In particular, we helped people understand the following essential points:- The total phase of the eclipse is only visible from a limited path.- The partial eclipse is visible from a large area outside the path of totality.- The eclipse takes up to three hours from start to finish, providing ample time for viewing.- The Sun can be observed safely using several methods, including but not limited to eclipse glasses.- The eclipse happens because the Moon’s orbit is taking it directly between the Sun and the Earth.- Eclipses do not happen every month because the Moon’s orbit is tilted with respect to the Earth's orbital plane.- Students in schools can safely view the eclipse, with proper protection and supervision, to prevent eye damage and minimize liability.Public education about the eclipse appears to have been successful, as evidenced by the large number of people who saw their first total solar eclipse and the absence of reported eye damage cases. Amidst the excitement, photographs, and stories that

    Successful IYPE activities and implementation of Geoheritage day in Lithuania increased public awareness in geology. A series of projects introducing geology to the general public and youth, supported by EU funds and local communities, were initiated. Researchers from the scientific and applied geology institutions of Lithuania participated in these projects and provided with the geological data. In one case, the Lithuanian Survey of Protected Areas supported the installation of a series of geological exhibitions in several regional and national parks. An animation demonstrating glacial processes was chosen for most of these because the Lithuanian surface is largely covered with sedimentary deposits of the Nemunas (Weichselian) glaciation. Researchers from the Lithuanian Geological Survey used the mapping results to demonstrate real glacial processes for every chosen area. In another case, 3D models showing underground structures of different localities were based on detailed geological maps and profiles obtained for that area. In case of the Sartai regional park, the results of previous geological research projects provided the possibility to create a movie depicting the ca. 2 Ga geological evolution of the region. The movie starts with the accretion of volcanic island arcs on the earlier continental margin at ca. 2 Ga and deciphers later Precambrian tectonic and magmatic events. The reconstruction is based on numerous scientific articles and interpretation of geophysical data. Later Paleozoic activities and following erosion sculptured the surface which was covered with several ice sheets in Quaternary. For educational purpose, a collection of minerals and rocks at the Forestry Institute was used to create an exhibition called "Cycle of geological processes". Forestry scientists and their students are able to study the interactions of geodiversity and biodiversity and to understand ancient and modern geological processes leading to a soil formation.

    Recent reports of national commissions and study groups have pointed out that the American educational system is not meeting the needs of its students. Uniformly, the reports call for a new instructional focus designed to achieve the goal of ''universal scientific and technological literacy for citizenship.'' The population's inability to deal with numerous controversial science-related social issues forms the basis for this call for educational reform. Foremost on the list of science-related social issues are nuclear issues in general and the storage of nuclear waste in particular. The National Council for the Social Studies (NCSS) 1983 publication ''Guidelines for Teaching Science Related Social Issues'' was designed to encourage stronger instructional emphasis on science-related social issues, and to provide social studies teachers with a rational and structure for the presentation of the issues. This paper discusses the dilemmas faced by educators who attempt to deal with science-related social issues. Also, it addresses the need for instructional materials in order to effectively address nuclear issues in the classroom

    Germline mutations in the PMS2 gene are an uncommon cause of Lynch Syndrome (LS), present in PMS2 immunohistochemical expression, with retained MLH1 expression, triggers referral to genetics services due to the significant risk of LS 3 . As detection of PMS2 germline mutations is problematic 4 , this may result in patients being labeled as "Lynch-like", with implications for future surveillance 5 . A recent study suggested that some cases of isolated PMS2 loss result from MLH1 promoter methylation and are sporadic rather than likely LS 6 ; they therefore recommended MLH1 promoter methylation testing in all cases of isolated PMS2 loss 6 .

    The fabrication of a miniature spark counter for public communication and education using naturally occurring radon as a radioactive source without involving any man-made radioactivity is described. The battery-powered miniature spark counter weighs 2.07 kg with a volume of 4.844 x 10/sup -4/ m/sup 3/. The circuitry consists of seven major components: timer, high-voltage power supply, attenuator, noninverting amplifier, low-pass filter, one-shot generator, and counter. Cellulose nitrate films irradiated with alpha particles from radon emanating from soil were etched and counted. The visible sparks during counting are rather heuristic, which can be used to demonstrate naturally occurring radioactivity in classrooms or showplaces

    Full Text Available Universities cater mainly for national audiences. But the days of splendid isolation are over. Students, graduates, faculty and staff vote with their feet. Institutions and system are, increasingly, involved in processes of regionalisation and globalisation. This article describes how a number of European initiatives are transforming the way universities operate in education, research and management. Incentives for change range from earmarked funding to projects grants and loans, from voluntary networking and benchmarking to quality audits and rankings. These instruments for change have become part of the fabric of university life, often consolidated in institutional strategies and national legislation. They are emerging as 'European public goods'. This article highlights a number of these initiatives in the various categories and points at their impact on university practice.

    Colorectal cancer (CRC) is the second most common cause of cancer-related deaths in the Western world and interactions between genetic and environmental factors, including diet, are suggested to play a critical role in its etiology. We conducted a long-term feeding experiment in the mouse to address gene expression and methylation changes arising in histologically normal colonic mucosa as putative cancer-predisposing events available for early detection. The expression of 94 growth-regulatory genes previously linked to human CRC was studied at two time points (5 weeks and 12 months of age) in the heterozygote Mlh1 +/- mice, an animal model for human Lynch syndrome (LS), and wild type Mlh1 +/+ littermates, fed by either Western-style (WD) or AIN-93G control diet. In mice fed with WD, proximal colon mucosa, the predominant site of cancer formation in LS, exhibited a significant expression decrease in tumor suppressor genes, Dkk1, Hoxd1, Slc5a8, and Socs1, the latter two only in the Mlh1 +/- mice. Reduced mRNA expression was accompanied by increased promoter methylation of the respective genes. The strongest expression decrease (7.3 fold) together with a significant increase in its promoter methylation was seen in Dkk1, an antagonist of the canonical Wnt signaling pathway. Furthermore, the inactivation of Dkk1 seems to predispose to neoplasias in the proximal colon. This and the fact that Mlh1 which showed only modest methylation was still expressed in both Mlh1 +/- and Mlh1 +/+ mice indicate that the expression decreases and the inactivation of Dkk1 in particular is a prominent early marker for colon oncogenesis.

    Genetic, physiological and environmental factors are implicated in colorectal carcinogenesis. Mutations in the mutL homolog 1 (MLH1) gene, one of the DNA mismatch repair genes, are a main cause of hereditary colon cancer syndromes such as Lynch syndrome. Long-term chronic inflammation is also a key risk factor, responsible for colitis-associated colorectal cancer; radiation exposure is also known to increase colorectal cancer risk. Here, we studied the effects of radiation exposure on inflammation-induced colon carcinogenesis in DNA mismatch repair-proficient and repair-deficient mice. Male and female Mlh1(-/-) and Mlh1(+/+) mice were irradiated with 2 Gy X-rays when aged 2 weeks or 7 weeks and/or were treated with 1% dextran sodium sulfate (DSS) in drinking water for 7 days at 10 weeks old to induce mild inflammatory colitis. No colon tumors developed after X-rays and/or DSS treatment in Mlh1(+/+) mice. Colon tumors developed after DSS treatment alone in Mlh1(-/-) mice, and exposure to radiation prior to DSS treatment increased the number of tumors. Histologically, colon tumors in the mice resembled the subtype of well-to-moderately differentiated adenocarcinomas with tumor-infiltrating lymphocytes of human Lynch syndrome. Immunohistochemistry revealed that expression of both p53 and β-catenin and loss of p21 and adenomatosis polyposis coli proteins were observed at the later stages of carcinogenesis, suggesting a course of molecular pathogenesis distinct from typical sporadic or colitis-associated colon cancer in humans. In conclusion, radiation exposure could further increase the risk of colorectal carcinogenesis induced by inflammation under the conditions of Mlh1 deficiency. © 2014 The Authors.

  2. Public Health Education: Teaching Epidemiology in High School Classrooms.

    Science.gov (United States)

    D'Agostino, Emily

    2018-03-01

    Epidemiology instruction has expanded at the undergraduate level in part because it increases student critical thinking and scientific literacy, promotes students' perception of public health as both practical and relevant, and empowers students as independent, lifelong learners. Why then are more high schools not adopting epidemiology as a course requirement for students? Although prior iterations of high school epidemiology courses are noteworthy for incorporating active and participatory learning, embedding them into existing and continually shifting curricula is challenging and time-consuming, especially for teachers not trained in the field. It also may be argued that currently available epidemiology teaching resources emphasize content rather than thinking skills and therefore do not optimally promote students' personal engagement with, and in-depth understanding of, the mission and goals of public health. I propose a new framework for high school epidemiology that draws from progressive education ideology, including three critical elements: empowerment, authenticity, and transfer. I provide multiple examples to show how this framework has been used across a wide array of settings to hone epidemiology thinking skills in high school students.

    Full Text Available The research explores the relationship between sexism and homophobia in adolescents of a public educational institution in Chimbote. The research design was descriptive - correlational and a sample of 406 students between males and females from 1st to 5th level of secondary education. As a measure they were evaluated with the Scale of Detection of Sexism of Ramos, Cuadrado and Recio (2007 adaptation of Acosta (2010 and the scale of modern homophobia of Raja and Stokes (2005 adaptation of Paredes (2013. The results of the research reflect a very significant, direct and strong relationship that indicates that the more sexism in adolescents, the more homophobic attitudes they can show. For hostile sexism and homophobia towards gay, a correlation of (r =.641 ** p <.01 and for lesbians (r =. 658 ** p <.01 was obtained; between gay sexism and homophobia towards gay (r =.574 ** p <.01 and towards lesbians (r =.646 ** p <.01. Levels of sexism by gender are identified as a high level of hostile and benevolent sexism for the male population with 14.1% and 15.7% respectively. There are also levels of homophobia according to gender in adolescents to gay and lesbian people with 35.3% and 25.3%

    A positive family history, germline mutations in DNA mismatch repair genes, tumours with high microsatellite instability, and loss of mismatch repair protein expression are the hallmarks of hereditary non-polyposis colorectal cancer (Lynch syndrome). However, in ~10-15% of cases of suspected Lynch syndrome, no disease-causing mechanism can be detected. Oligo array analysis was performed to search for genomic imbalances in patients with suspected mutation-negative Lynch syndrome with MLH1 deficiency in their colorectal tumours. A deletion in the LRRFIP2 (leucine-rich repeat flightless-interacting protein 2) gene flanking the MLH1 gene was detected, which turned out to be a paracentric inversion on chromosome 3p22.2 creating two new stable fusion transcripts between MLH1 and LRRFIP2. A single-nucleotide polymorphism in MLH1 exon 8 was expressed from both alleles, initially pointing to appropriate MLH1 function at least in peripheral cells. In a second case, an inherited duplication of the MLH1 gene region resulted in constitutional MLH1 promoter methylation. Constitutional MLH1 promoter methylation may therefore in rare cases be a heritable disease mechanism and should not be overlooked in seemingly sporadic patients.

    The aim of this study was to evaluate the methylation status of the promoter region of MLH1 gene in colorectal cancer (CRC) and its precursor lesions as well as elucidate its association with various clinicopathological characteristics among Iranian population. Epigenetic silencing of mismatch repair genes, such as MLH1 , by methylation of CpG islands of their promoter region has been proved to be an important mechanism in colorectal carcinogenesis. Fifty colorectal cancer and polyp tissue samples including 13 Primary colorectal tumor and 37 Adenoma polyp samples were enrolled in this study. Methylation-specific polymerase chain reaction (MSP) was performed to find the frequency of MLH1 Promoter Methylation. Promoter methylation of MLH1 gene was detected in 5 out of 13 tumor tissues and 4 out of 37 adenoma polyp. The frequency of MLH1 methylation in tumor samples was significantly higher compared to that in polyp tissues (P= 0.026). No significant association was observed between MLH1 promoter methylation and clinicopathological characteristics of the patients. The frequency of  MLH1  promoter methylation in CRC and colon polyp was 18%. Our findings indicated that methylation of MLH1 promoter region alone cannot be considered as a biomarker for early detection of CRC.

    Germline mutations of the DNA mismatch repair genes MLH1, MSH2, MSH6 or PMS2, and deletions affecting the EPCAM gene adjacent to MSH2, underlie Lynch syndrome by predisposing to early-onset colorectal, endometrial and other cancers. An alternative but rare cause of Lynch syndrome is constitutional epimutation of MLH1, whereby promoter methylation and transcriptional silencing of one allele occurs throughout normal tissues. A dominantly transmitted constitutional MLH1 epimutation has been linked to an MLH1 haplotype bearing two single-nucleotide variants, NM_000249.2: c.-27C>A and c.85G>T, in a Caucasian family with Lynch syndrome from Western Australia. Subsequently, a second seemingly unrelated Caucasian Australian case with the same MLH1 haplotype and concomitant epimutation was reported. We now describe three additional, ostensibly unrelated, cancer-affected families of European heritage with this MLH1 haplotype in association with constitutional epimutation, bringing the number of index cases reported to five. Array-based genotyping in four of these families revealed shared haplotypes between individual families that extended across ≤2.6-≤6.4 megabase regions of chromosome 3p, indicating common ancestry. A minimal ≤2.6 megabase founder haplotype common to all four families was identified, which encompassed MLH1 and additional flanking genes and segregated with the MLH1 epimutation in each family. Our findings indicate that the MLH1 c.-27C>A and c.85G>T variants are borne on a European ancestral haplotype and provide conclusive evidence for its pathogenicity via a mechanism of epigenetic silencing of MLH1 within normal tissues. Additional descendants bearing this founder haplotype may exist who are also at high risk of developing Lynch syndrome-related cancers.

    Germline defects in MLH1 , MSH2 , MSH6 and PMS2 predisposing for Lynch syndrome (LS) are mainly based on sequence changes, whereas a constitutional epimutation of MLH1 (CEM) is exceptionally rare. This abnormal MLH1 promoter methylation is not hereditary when arising de novo, whereas a stably heritable and variant-induced CEM was described for one single allele. We searched for MLH1 promoter variants causing a germline or somatic methylation induction or transcriptional repression. We analysed the MLH1 promoter sequence in five different patient groups with colorectal cancer (CRC) (n=480) composed of patients with i) CEM (n=16), ii) unsolved loss of MLH1 expression in CRC (n=37), iii) CpG-island methylator-phenotype CRC (n=102), iv) patients with LS (n=83) and v) MLH1-proficient CRC (n=242) as controls. 1150 patients with non-LS tumours also served as controls to correctly judge the results. We detected 10 rare MLH1 promoter variants. One novel, complex MLH1 variant c.-63_-58delins18 is present in a patient with CRC with CEM and his sister, both showing a complete allele-specific promoter methylation and transcriptional silencing. The other nine promoter variants detected in 17 individuals were not associated with methylation. For four of these, a normal, biallelic MLH1 expression was found in the patients' cDNA. We report the second promoter variant stably inducing a hereditary CEM. Concerning the classification of promoter variants, we discuss contradictory results from the literature for two variants, describe classification discrepancies between existing rules for five variants, suggest the (re-)classification of five promoter variants to (likely) benign and regard four variants as functionally unclear. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The Incorporated Research Institutions for Seismology's Education and Public Outreach (EPO) program is committed to advancing awareness and understanding of seismology and geophysics, while inspiring careers in the Earth sciences. To achieve this mission, IRIS EPO combines content and research expertise of consortium membership with educational and outreach expertise of IRIS staff to create a portfolio of programs, products, and services that target a range of audiences, including grades 6-12 students and teachers, undergraduate and graduate students, faculty, and the general public. IRIS also partners with UNAVCO and other organizations in support of EarthScope where the facilities are well-suited for sustained engagement of multiple audiences. Examples of research-related EPO products and services include the following resources. Tools developed in collaboration with IRIS Data Services provide public and educational access to data, and to a suite of data products. Teachers can stream seismic data from educational or research sensors into their classroom, and the Active Earth Monitor display, designed for visitor centers, universities and small museums, provides views of recent data along with animations that explain seismology concepts, and stories about recent research. Teachable Moment slide sets, created in collaboration with the University of Portland within 24 hours of major earthquakes, provide interpreted USGS tectonic maps and summaries, animations, visualizations, and other event-specific information so educators can explore newsworthy earthquakes with their students. Intro undergraduate classroom activities have been designed to introduce students to some grand challenges in seismological research, while our Research Experiences for Undergraduates program pairs students with seismology researchers throughout the Consortium and provides the opportunity for the students to present their research at a national meeting.

    Full Text Available In Participation in physical education is considered to be a fundamental right of pupils all over the world. In Hungary, where the rich elite sports traditions of the country are paralleled by the population’s moderate physical activity, the challenge posed by non-communicable diseases and growing obesity figures among youth was addressed by the introduction of daily P.E. in public education starting in the 2012/13 academic year. The objective of the present paper is to discuss, based on empirical research, the intended and unintended consequences of this measure in an educational and social context using the qualitative analysis of the views of key stakeholders and the quantitative analysis of statistical data on the infrastructural and personal conditions of P.E. The results indicate that neither before nor after the enforcement of the Act on Public Education were the infrastructural and personal conditions of daily P.E. created and, in addition to the intended consequences, a number of unintended consequences have also been encountered by various stakeholders. The study can also be regarded as an attempt to reveal these dysfunctions in order to contribute to positive changes in the area.

    Full Text Available The Educated Citizen Initiative proposes that an understanding of public health issues is a core component of an educated citizenry and is essential to developing one’s societal responsibility. This initiative supports the Institute of Medicine’s recommendation that all undergraduates should have access to education in public health. Furthermore, the Liberal Education and America’s Promise (LEAP framework developed by the Association of American Colleges and Universities supports the integration of public health education into general and liberal education with an aim to produce an educated citizenry. The LEAP framework is implemented by teaching about the role of social determinants in a population’s health status; the significance of personal and social responsibility; and providing skills for inquiry, critical thinking, problem solving, and evaluation. This article describes one university’s experience in generating an educated citizenry cognizant of comprehensive public health conflicts, thus contributing to both a local and global perspective on learning.

    NASA’s Frontier Fields is an ambitious three-year Great Observatories program that will expand our understanding of galaxy formation and evolution in the early universe. The program includes six deep-field observations of strong-lensing galaxy clusters that will be taken in parallel with six deep “blank fields.” The observations allow astronomers to look deeper into the universe than ever before, and potentially uncover galaxies that are as much as 100 times fainter than what the telescopes can typically observe. The Frontier Fields science program is ideal for informing audiences about scientific advances and topics in STEM. The study of galaxy properties, statistics, optics, and Einstein’s theory of general relativity naturally leverages off of the science returns of the Frontier Fields program. As a result, the Space Telescope Science Institute’s Office of Public Outreach (OPO) has initiated an E/PO project to follow the progress of the Frontier Fields.For over two decades, the Hubble E/PO program has sought to bring the wonders of the universe to the education community, the youth, and the public, and engage audiences in the adventure of scientific discovery. Program components include standards-based curriculum-support materials, exhibits and exhibit components, professional development workshops, and direct interactions with scientists. We are also leveraging our new social media strategy to bring the science program to the public in the form of an ongoing blog. The main underpinnings of the program’s infrastructure are scientist-educator development teams, partnerships, and an embedded program evaluation component. OPO is leveraging this existing infrastructure to bring the Frontier Fields science program to the education community and the public in a cost-effective way.This talk features the goals and current status of the Frontier Fields E/PO program, with a particular emphasis on our education goals and achievements.

    Poly(ADP-ribose) polymerase inhibitors (PARPi) are currently evaluated in clinical trials in combination with topoisomerase I (Top1) inhibitors against a variety of cancers, including colon carcinoma. Since the mismatch repair component MLH1 is defective in 10-15% of colorectal cancers we have investigated whether MLH1 affects response to the Top1 inhibitor irinotecan, alone or in combination with PARPi. To this end, the colon cancer cell lines HCT116, carrying MLH1 mutations on chromosome 3 and HCT116 in which the wild-type MLH1 gene was replaced via chromosomal transfer (HCT116+3) or by transfection of the corresponding MLH1 cDNA (HCT116 1-2) were used. HCT116 cells or HCT116+3 cells stably silenced for PARP-1 expression were also analysed. The results of in vitro and in vivo experiments indicated that MLH1, together with low levels of Top1, contributed to colon cancer resistance to irinotecan. In the MLH1-proficient cells SN-38, the active metabolite of irinotecan, induced lower levels of DNA damage than in MLH1-deficient cells, as shown by the weaker induction of γ-H2AX and p53 phosphorylation. The presence of MLH1 contributed to induce of prompt Chk1 phosphorylation, restoring G2/M cell cycle checkpoint and repair of DNA damage. On the contrary, in the absence of MLH1, HCT116 cells showed minor Chk1 phosphorylation and underwent apoptosis. Remarkably, inhibition of PARP function by PARPi or by PARP-1 gene silencing always increased the antitumor activity of irinotecan, even in the presence of low PARP-1 expression.

    Germ-line mutations in the DNA mismatch repair genes MLH1, MSH2, and MSH6 predispose to the development of colorectal cancer (Lynch syndrome or hereditary nonpolyposis colorectal cancer). These mutations include disease-causing frame-shift, nonsense, and splicing mutations as well as large genomic rearrangements. However, a large number of mutations, including missense, silent, and intronic variants, are classified as variants of unknown clinical significance. Intronic MLH1, MSH2, or MSH6 variants were investigated using in silico prediction tools and mini-gene assay to asses the effect on splicing. We describe in silico and in vitro characterization of nine intronic MLH1, MSH2, or MSH6 mutations identified in Danish colorectal cancer patients, of which four mutations are novel. The analysis revealed aberrant splicing of five mutations (MLH1 c.588 + 5G > A, MLH1 c.677 + 3A > T, MLH1 c.1732-2A > T, MSH2 c.1276 + 1G > T, and MSH2 c.1662-2A > C), while four mutations had no effect on splicing compared to wild type (MLH1 c.117-34A > T, MLH1 c.1039-8 T > A, MSH2 c.2459-18delT, and MSH6 c.3439-16C > T). In conclusion, we classify five MLH1/MSH2 mutations as pathogenic, whereas four MLH1/MSH2/MSH6 mutations are classified as neutral. This study supports the notion that in silico prediction tools and mini-gene assays are important for the classification of intronic variants, and thereby crucial for the genetic counseling of patients and their family members.

    BACKGROUND: The human MLH1 gene (hMLH1) is one of the DNA mismatch repair genes. Defects in these genes are believed to be the underlying cause of microsatellite instability (MSI). MSI has been demonstrated in many human cancers such as colon cancer and some female-specific tumors. The hMLH1 gene

    We previously developed a novel tumor subtype classification model for duodenal adenocarcinomas based on a combination of the CpG island methylator phenotype (CIMP) and MLH1 methylation status. Here, we tested the prognostic value of this model in stage II colorectal cancer (CRC) patients. Tumors were assigned to CIMP+/MLH1-unmethylated (MLH1-U), CIMP+/MLH1-methylated (MLH1-M), CIMP-/MLH1-U, or CIMP-/MLH1-M groups. Age, tumor location, lymphovascular invasion, and mucin production differed among the four patient subgroups, and CIMP+/MLH1-U tumors were more likely to have lymphovascular invasion and mucin production. Kaplan-Meier analyses revealed differences in both disease-free survival (DFS) and overall survival (OS) among the four groups. In a multivariate analysis, CIMP/MLH1 methylation status was predictive of both DFS and OS, and DFS and OS were shortest in CIMP+/MLH1-U stage II CRC patients. These results suggest that tumor subtype classification based on the combination of CIMP and MLH1 methylation status is informative in stage II CRC patients, and that CIMP+/MLH1-U tumors exhibit aggressive features and are associated with poor clinical outcomes.

    Recent surveys indicate that approximately 40% of graduates from schools of public health are employed within the private sector or have an employer charged with regulating the private sector. These data suggest that schools of public health should provide curricular opportunities for their students--the future public health workforce--to learn about the relationship between the private sector and the public's health. To identify opportunities for graduate students in schools of public health to select course work that educates them about the relationship between the private sector and public health. We systematically identified and analyzed data gathered from publicly available course titles and descriptions on the Web sites of accredited schools of public health. Data were collected in the United States. The sample consisted of accredited schools of public health. Descriptions of the number and types of courses that schools of public health offer about the private sector and identification of how course descriptions frame the private sector relative to public health. We identified 104 unique courses with content about the private sector's relationship to public health. More than 75% of accredited schools of public health offered at least 1 such course. Nearly 25% of identified courses focused exclusively on the health insurance industry. Qualitative analysis of the data revealed 5 frames used to describe the private sector, including its role as a stakeholder in the policy process. Schools of public health face a curricular gap, with relatively few course offerings that teach students about the relationship between the private sector and the public's health. By developing new courses or revising existing ones, schools of public health can expose the future public health workforce to the varied ways public health professionals interact with the private sector, and potentially influence students' career paths.

    Full Text Available This mixed method study sought to explore the issues that faced secondary teachers in a rural central Georgia public high school when attempting to implement a multicultural education program.  The key issues of this study centered on the teachers’ multicultural education training and the school’s multicultural education program. Data were gathered from a total of thirty randomly chosen teachers in the Social Studies, Math and English departments at the school. Twenty-five of the thirty teachers received a hard copy four question Likert scale survey to complete. The remaining 5 participants took part in face-to-face interviews discussing six open-ended questions.  The findings pointed to several issues facing the teachers such as the lack of an officially implemented multicultural education program, the lack of support from school administrators, no in-service training available for teachers, parental and student misapprehension, and a lack of an officially defined policy on implementation and support of a multicultural education program from administrators locally and district-wide.

    Constitutional epimutations of DNA mismatch repair (MMR) genes have been recently reported as a possible cause of Lynch syndrome. However, little is known about their prevalence, the risk of transmission through the germline and the risk for carriers to develop cancers. In this study, we evaluated the contribution of constitutional epimutations of MMR genes in Lynch syndrome. A cohort of 134 unrelated Lynch syndrome-suspected patients without MMR germline mutation was screened for constitutional epimutations of MLH1 and MSH2 by quantitative bisulfite pyrosequencing. Patients were also screened for the presence of EPCAM deletions, a possible cause of MSH2 methylation. Tumors from patients with constitutional epimutations were extensively analyzed. We identified a constitutional MLH1 epimutation in two proband patients. For one of them, we report for the first time evidence of transmission to two children who also developed early colonic tumors, indicating that constitutional MLH1 epimutations are associated to a real risk of transgenerational inheritance of cancer susceptibility. Moreover, a somatic BRAF mutation was detected in one affected child, indicating that tumors from patients carrying constitutional MLH1 epimutation can mimic MSI-high sporadic tumors. These findings may have important implications for future diagnostic strategies and genetic counseling. © 2011 Wiley Periodicals, Inc.

    It was shown that Lynch syndrome can be caused by germline hypermethylation of the MLH1 and MSH2 promoters. Furthermore, it has been demonstrated very recently that germline deletions of the 3' region of EPCAM cause transcriptional read-through which results in silencing of MSH2 by hypermethylation.

    Gastric carcinoma (GC) has one of the highest mortality rates of cancer diseases and has a high incidence rate in China. Palliative chemotherapy is the main treatment for advanced gastric cancer. It is necessary to compare the effectiveness and toxicities of different regimens. This study explores the possibility of methylation of DNA damage repair genes serving as a prognostic and chemo-sensitive marker in human gastric cancer. The methylation status of five DNA damage repair genes (CHFR, FANCF, MGMT, MLH1, and RASSF1A) was detected by nested methylation-specific PCR in 102 paraffin-embedded gastric cancer samples. Chi-square or Fisher's exact tests were used to evaluate the association of methylation status and clinic-pathological factors. The Kaplan-Meier method and Cox proportional hazards models were employed to analyze the association of methylation status and chemo-sensitivity. The results indicate that CHFR, MLH1, RASSF1A, MGMT, and FANCF were methylated in 34.3% (35/102), 21.6% (22/102), 12.7% (13/102), 9.8% (10/102), and 0% (0/102) of samples, respectively. No association was found between methylation of CHFR, MLH1, RASSF1A, MGMT, or FANCF with gender, age, tumor size, tumor differentiation, lymph node metastasis, and TNM stage. In docetaxel-treated gastric cancer patients, resistance to docetaxel was found in CHFR unmethylated patients by Cox proportional hazards model (HR 0.243, 95% CI, 0.069-0.859, p = 0.028), and overall survival is longer in the CHFR methylated group compared with the CHFR unmethylated group (log-rank, p = 0.036). In oxaliplatin-treated gastric cancer patients, resistance to oxaliplatin was found in MLH1 methylated patients (HR 2.988, 95% CI, 1.064-8.394, p = 0.038), and overall survival was longer in the MLH1 unmethylated group compared with the MLH1 methylated group (log-rank, p = 0.046). CHFR is frequently methylated in human gastric cancer, and CHFR methylation may serve as a docetaxel-sensitive marker. MLH1 methylation was

    2016-01-01

    Full Text Available Public perception of bats has historically been largely negative with bats often portrayed as carriers of disease. Bats are commonly associated with vampire lore and thus elicit largely fearful reactions despite the fact that they are a vital and valuable part of the ecosystem. Bats provide a variety of essential services from pest control to plant pollination. Despite the benefits of bats to the environment and the economy, bats are suffering at the hands of humans. They are victims of turbines, human encroachment, pesticides, and, most recently, white nose syndrome. Because of their critical importance to the environment, humans should do what they can to help protect bats. We propose that humans will be more likely to do so if their perceptions and attitudes toward bats can be significantly improved. In a preliminary study we found some support for the idea that people can be educated about bats through bat oriented events and exhibits, and that this greater knowledge can inspire humans to act to save bats.

    Over the past two decades, 33 cases of colonic adenocarcinomas have been diagnosed in rhesus macaques ( Macaca mulatta ) at the nonhuman primate colony of the Keeling Center for Comparative Medicine and Research at The University of Texas MD Anderson Cancer Center. The distinctive feature in these cases, based on PET/computed tomography (CT) imaging, was the presence of two or three tumor lesions in different locations, including proximal to the ileocecal juncture, proximal to the hepatic flexure, and/or in the sigmoid colon. These colon carcinoma lesions selectively accumulated [ 18 F]fluorodeoxyglucose ([ 18 F]FDG) and [ 18 F]fluoroacetate ([ 18 F]FACE) at high levels, reflecting elevated carbohydrate and fatty acid metabolism in these tumors. In contrast, the accumulation of [ 18 F]fluorothymidine ([ 18 F]FLT) was less significant, reflecting slow proliferative activity in these tumors. The diagnoses of colon carcinomas were confirmed by endoscopy. The expression of MLH1, MSH2, and MSH6 proteins and the degree of microsatellite instability (MSI) was assessed in colon carcinomas. The loss of MLH1 protein expression was observed in all tumors and was associated with a deletion mutation in the MLH1 promoter region and/or multiple single-nucleotide polymorphism (SNP) mutations in the MLH1 gene. All tumors exhibited various degrees of MSI. The pedigree analysis of this rhesus macaque population revealed several clusters of affected animals related to each other over several generations, suggesting an autosomal dominant transmission of susceptibility for colon cancer. The newly discovered hereditary nonpolyposis colorectal cancer syndrome in rhesus macaques, termed MLH1 -rheMac, may serve as a model for development of novel approaches to diagnosis and therapy of Lynch syndrome in humans.

    Approximately 15% of colorectal carcinomas (CRC) exhibit a hypermutated genotype accompanied by high levels of microsatellite instability (MSI-H) and defects in DNA mismatch repair. These tumors, unlike the majority of colorectal carcinomas, are often diploid, exhibit frequent epigenetic silencing of the MLH1 DNA mismatch repair gene, and have a better clinical prognosis. As an adjunct study to The Cancer Genome Atlas consortium that recently analyzed 224 colorectal cancers by whole exome sequencing, we compared the 35 CRC (15.6%) with a hypermutated genotype to those with a non-hypermutated genotype. We found that 22 (63%) of hypermutated CRC exhibited transcriptional silencing of the MLH1 gene, a high frequency of BRAF V600E gene mutations and infrequent APC and KRAS mutations, a mutational pattern significantly different from their non-hypermutated counterparts. However, the remaining 13 (37%) hypermutated CRC lacked MLH1 silencing, contained tumors with the highest mutation rates (“ultramutated” CRC), and exhibited higher incidences of APC and KRAS mutations, but infrequent BRAF mutations. These patterns were confirmed in an independent validation set of 250 exome-sequenced CRC. Analysis of mRNA and microRNA expression signatures revealed that hypermutated CRC with MLH1 silencing had greatly reduced levels of WNT signaling and increased BRAF signaling relative non-hypermutated CRC. Our findings suggest that hypermutated CRC include one subgroup with fundamentally different pathways to malignancy than the majority of CRC. Examination of MLH1 expression status and frequencies of APC, KRAS, and BRAF mutation in CRC may provide a useful diagnostic tool that could supplement the standard microsatellite instability assays and influence therapeutic decisions.

    hMLH1 gene, lying on chromosome 3p21-23, is a key factor of the mismatch repair (MMR) complex, which amends DNA replication errors. MMR alterations are involved in the development of both hereditary and sporadic forms of colorectal carcinoma related to ulcerative colitis (UC). I219V Polymorphism is located on exon 8 of hMLH1 and provides an aminoacidic substitution of isoleucine to valine, on the protein codon 219. This may affect the speed and fidelity of protein synthesis because of a tRNA paucity or changes in the mRNA secondary structure. Most of the hereditary nonpolyposis colon cancer-associated missense mutations of hMLH1 cause structural changes of the amino- or carboxy-terminal regions, involving the domains that interact with ATP and hPMS2. In this study, we analyzed the hMLH1 I219V polymorphism frequency in colectomized patients with UC. Venous blood from 100 ulcerative patients and 97 apparently healthy subjects has been collected. Out of 100 patients affected with UC, 75 noncolectomized showed an alternating course of disease, while 25 did not respond to the common drugs, and underwent colectomy. Genotyping was performed by polymerase chain reaction and following enzymatic digestion by BccI. No significant differences were found between patients with UC and controls both for genotype and allele frequencies. However, our data show a significant association when colectomized and noncolectomized patients are compared. The frequencies of G homozygosity were 28% in colectomized and 10.7% in noncolectomized patients (p < 0.05, chi(2) = 4.4, Odds ratio = 3.3). The allele frequencies of allele A were 52% in colectomized and 68% in noncolectomized patients; while those of allele G were 48% and 32%, respectively. I219V polymorphism in hMLH1 could influence the clinical course of the disease and lead to resistance to therapy.

    Missense alterations of the mismatch repair gene MLH1 have been identified in a significant proportion of individuals suspected of having Lynch syndrome, a hereditary syndrome that predisposes for cancer of colon and endometrium. The pathogenicity of many of these alterations, however, is unclear. A number of MLH1 alterations are located in the C-terminal domain (CTD) of MLH1, which is responsible for constitutive dimerization with PMS2. We analyzed which alterations may result in pathogenic effects due to interference with dimerization. We used a structural model of CTD of MLH1-PMS2 heterodimer to select 19 MLH1 alterations located inside and outside two candidate dimerization interfaces in the MLH1-CTD. Three alterations (p.Gln542Leu, p.Leu749Pro, p.Tyr750X) caused decreased coexpression of PMS2, which is unstable in the absence of interaction with MLH1, suggesting that these alterations interfere with dimerization. All three alterations are located within the dimerization interface suggested by our model. They also compromised mismatch repair, suggesting that defects in dimerization abrogate repair and confirming that all three alterations are pathogenic. Additionally, we provided biochemical evidence that four alterations with uncertain pathogenicity (p.Ala586Pro, p.Leu636Pro, p.Thr662Pro, and p.Arg755Trp) are deleterious because of poor expression or poor repair efficiency, and confirm the deleterious effect of eight further alterations.

    Background: The promoter methylation of MLH1 gene and gastric cancer (GC)has been investigated previously. To get a more credible conclusion, we performed a systematic review and meta and bioinformatic analysis to clarify the role of MLH1 methylation in the prediction and prognosis of GC. Methods: Eligible studies were targeted after searching the PubMed, Web of Science, Embase, BIOSIS, CNKI and Wanfang Data to collect the information of MLH1 methylation and GC. The link strength between the two was estimated by odds ratio with its 95% confidence interval. The Newcastle-Ottawa scale was used for quantity assessment . Subgroup and sensitivity analysis were conducted to explore sources of heterogeneity. The Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) were employed for bioinformatics analysis on the correlation between MLH1 methylation and GC risk, clinicopathological behavior as well as prognosis. Results: 2365 GC and 1563 controls were included in the meta-analysis. The pooled OR of MLH1 methylation in GC was 4.895 (95% CI: 3.149-7.611, PMLH1 methylation enhanced GC risk but might not related with GC clinicopathological features and prognosis. Conclusion: MLH1 methylation is an alive biomarker for the prediction of GC and it might not affect GC behavior. Further study could be conducted to verify the impact of MLH1 methylation on GC prognosis.

    Gene silencing of the repair genes MLH1 and MGMT was shown to be a mechanism underlying the development of microsatellite instability (MSI), a phenotype frequently associated with various human malignancies. Recently, aberrant methylation of MLH1, MGMT and MSI were shown to be associated with mutations in genes such as BRAF, RAS and IDH1 in colon and brain tumours. Little is known about the methylation status of MLH1 and MGMT in thyroid tumours and its association with MSI and mutational status. In a series of 96 thyroid tumours whose mutational profiles of BRAF, IDH1 and NRAS mutations and RET/PTC were previously determined, we investigated MLH1 and MGMT expression and methylation status by qPCR and methylation-specific PCR after bisulphite treatment, respectively. MSI was determined by PCR using seven standard microsatellite markers. Samples with point mutations (BRAF, IDH1 and NRAS) show a decrease in MLH1 expression when compared to negative samples. Additionally, malignant lesions show a higher MSI pattern than benign lesions. The MSI phenotype was also associated with down-regulation of MLH1. The results of this study allow us to conclude that low expression of MLH1 is associated with BRAF V600E mutations, RET/PTC rearrangements and transitions (IDH1 and NRAS) in patients with thyroid carcinoma. In addition, a significant relationship between MSI status and histological subtypes was found

    The aim of this study was to evaluate the effect of chronic smoking on the expression profile of the repair genes MLH1, MSH2 and ATM in the normal oral mucosa of chronic smokers and never smokers. The sample consisted of thirty exfoliative cytology smears per group obtained from Smokers and Never Smokers. Total RNA was extracted and expression of the MLH1, MSH2 and ATM genes were evaluated by quantitative real-time and immunocytochemistry. The gene and protein expression data were correlated to the clinical data. Gene expression was analyzed statistically using the Student t-test and Pearson's correlation coefficient, with pMLH1, MSH2 and ATM genes were downregulated in the smoking group compared to the control with significant values for MLH1 (p=0.006), MSH2 (p=0.0001) and ATM (p=0.0001). Immunocytochemical staining for anti-MLH1, anti-MSH2 and anti-ATM was negative in Never Smokers; in Smokers it was rarely positive. No significant correlation was observed among the expression of MLH1, MSH2, ATM and age, number of cigarettes consumed per day, time of smoking during life, smoking history or levels of CO in expired air. The expression of genes and proteins related to DNA repair mechanism MLH1, MSH2 and ATM in the normal oral mucosa of chronic smokers was reduced. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-07-01

    Given that endometrial cancer (EC) is often the sentinel cancer for female Lynch syndrome patients, we have successfully implemented universal screening of ECs and have previously shown that this is the preferred method to identify these patients. However, during the course of universal screening of EC, we encountered 6 cases with an unusual pattern of mismatch-repair protein immunohistochemistry that has not been previously described in this setting. In these 6 cases, there was an abrupt loss of MLH1 and PMS2 expression in a portion of the tumor. In 3 cases, marked histologic differences were identified between the areas of the tumor with retained expression and areas with loss of expression. In 2 cases, the areas with loss of expression were of higher grade (1 demonstrated solid growth and the other demonstrated increased nuclear atypia with diffuse p53 expression). In 4 tumors, histologic features associated with microsatellite instability (MSI) were present, including increased intraepithelial lymphocytes. The areas with loss of and retained MLH1/PMS2 expression were separately microdissected and assessed for MSI and MLH1 promoter methylation. The areas with loss of MLH1 and PMS2 more commonly demonstrated MSI compared with the areas with intact expression (83% vs. 33%). MLH1 promoter methylation analysis demonstrated heterogenous hypermethylation, as all areas with loss of MLH1/PMS2 expression had more extensive methylation of MLH1 compared with those areas with retained expression. In summary, we describe the histologic and molecular features of 6 cases of EC with abrupt loss of MLH1 and PMS2 expression and demonstrate that heterogenous methylation of the MLH1 promoter results in this distinct and unusual pattern of immunohistochemical expression.

    2017-03-01

    To determine the correlation between BRAF genotype and MLH1 promoter methylation in a screening program for Lynch syndrome (LS), a universal screening program for LS was established in two medical centers. Tumors with abnormal MLH1 staining were evaluated for both BRAF V600E genotype and MLH1 promoter methylation. Tumors positive for both were considered sporadic, and genetic testing was recommended for all others. A total 1011 colorectal cancer cases were screened for Lynch syndrome, and 148 (14.6%) exhibited absent MLH1 immunostaining. Both BRAF and MLH1 methylation testing were completed in 126 cases. Concordant results (both positive or both negative) were obtained in 86 (68.3%) and 16 (12.7%) cases, respectively, with 81% concordance overall. The positive and negative predictive values for a BRAF mutation in predicting MLH1 promoter methylation were 98.9% and 41%, respectively, and the negative predictive value fell to 15% in patients ≥70 years old. Using BRAF genotyping as a sole test to evaluate cases with absent MLH1 staining would have increased referral rates for genetic testing by 2.3-fold compared with MLH1 methylation testing alone (31% vs 13.5%, respectively, PMLH1 methylation testing for BRAF wild-type cases only would significantly decrease the number of methylation assays performed and reduce the referral rate for genetic testing to 12.7%. A BRAF mutation has an excellent positive predictive value but poor negative predictive value in predicting MLH1 promoter methylation. A hybrid use of these tests may reduce the number of low-risk patients referred to genetic counseling and facilitate wider implementation of Lynch syndrome screening programs.

    Can stories succeed where traditional forms of diplomacy have faltered? This study examined whether a primetime drama could impact American viewers’ knowledge, attitudes, and behavior with respect to U.S. foreign policy and funding by surveying 173 viewers of an episode of Law & Order: SVU (“Witness”). Additionally, this study sought to uncover which theoretical construct — involvement with a specific character or involvement with the narrative more generally (transportation) — best predicted impact. The fictional character in question was Nardelie, a woman forced to flee the Democratic Republic of the Congo after repeated rape by militias vying for “conflict minerals,” so named because control of these valuable minerals has triggered numerous conflicts. Separate regression analyses suggested a positive relationship between impact of the storyline and both theoretical constructs. However, when both constructs were entered into a single regression, involvement with Nardelie was the stronger predictor of knowledge (e.g., conflict minerals, sexual violence, and asylum issues) and current or future behavior (i.e., discussing global health) while transportation was the stronger predictor of attitudes (i.e., support for aid). This suggests that, while correlated, these constructs do not completely overlap. Implications of these results and the use of entertainment education in public diplomacy are discussed.

    Community - Scientist partnerships take many forms. In the northwest corner of Washington state a large, active, serpentinitic earthflow has, for decades, shed >25,000 m^3/yr of asbestos-rich sediment into a small agricultural stream system. While the landslide, which moves 3 m/yr, and its unusual sediment have much attracted scientific interest, the situation also presents a great opportunity for community - scientist partnerships. The Swift Creek Landslide Observatory (SCLO) (http://landslide.geol.wwu.edu) is a partnership between scientists and technical staff at Western Washington University + local landowners + the state Department of Ecology + Whatcom County Public Works + a local video security firm. SCLO maintains two remote webcams from which current images are posted to the SCLO website hourly. Users can also view archived images from the cameras, create image-compare visualizations, and create time-lapse movies from the eight-year image archive. SCLO is used by local emergency managers and residents to evaluate the threat of debris flows and floods. It is also used by educators to dramatically illustrate hillslope evolution at a variety of time scales.

    The prevalence of MLH1 constitutional epimutations in the general population is unknown. We sought to analyse the prevalence of MLH1 constitutional epimutations in unselected and selected series of patients with colorectal cancer (CRC). Patients with diagnoses of CRC (n=2123) were included in the unselected group. For comparison, a group of 847 selected patients with CRC who fulfilled the revised Bethesda guidelines (rBG) were also included. Somatic and constitutional MLH1 methylation was assayed via methylation-specific multiplex ligation-dependent probe amplification of cases lacking MLH1 expression. Germline alterations in mismatch-repair (MMR) genes were assessed via Sanger sequencing and methylation-specific multiplex ligation-dependent probe amplification. Loss of MLH1 expression occurred in 5.5% of the unselected series and 12.5% of the selected series (pMLH1 were detected in the unselected population (0/62); five cases from the selected series were positive for MLH1 epimutations (15.6%, 5/32; p=0.004). Our results suggest a negligible prevalence of MLH1 constitutional epimutations in unselected cases of CRC. Therefore, MLH1 constitutional epimutation analysis should be conducted only for patients who fulfil the rBG and who lack MLH1 expression with methylated MLH1.

    2013-07-01

    Although the presence of MLH1 methylation in microsatellite-unstable colorectal cancer generally indicates involvement of the CpG island methylator phenotype (CIMP) in the development of the tumor, these two conditions do not always correlate. A minority of microsatellite-unstable colorectal cancers exhibit discordance between CIMP and MLH1 methylation statuses. However, the clinicopathological features of such microsatellite-unstable colorectal cancers with discrepant MLH1 methylation and CIMP statuses remain poorly studied. Microsatellite-unstable colorectal cancers (n=220) were analyzed for CIMP and MLH1 methylation statuses using the MethyLight assay. Based on the combinatorial CIMP and MLH1 methylation statuses, the microsatellite-unstable colorectal cancers were grouped into four subtypes (CIMP-high (CIMP-H) MLH1 methylation-positive (MLH1m+), CIMP-H MLH1 methylation-negative, CIMP-low/0 (CIMP-L/0) MLH1m+, and CIMP-L/0 MLH1 methylation-negative), which were compared in terms of their associations with clinicopathological and molecular features. The CIMP-L/0 MLH1 methylation-negative and CIMP-H MLH1m+ subtypes were predominant, comprising 63.6 and 24.1% of total microsatellite-unstable colorectal cancers, respectively. The discordant subtypes, CIMP-H MLH1 methylation-negative and CIMP-L/0 MLH1m+, were found in 5 and 7% of microsatellite-unstable colorectal cancers, respectively. The CIMP-H MLH1 methylation-negative subtype exhibited elevated incidence rates in male patients and was associated with larger tumor size, more frequent loss of MSH2 expression, increased frequency of KRAS mutation, and advanced cancer stage. The CIMP-L/0 MLH1m+ subtype was associated with onset at an earlier age, a predominance of MLH1 loss, and earlier cancer stage. None of the CIMP-L/0 MLH1m+ subtype patients succumbed to death during the follow-up. Our findings suggest that the discordant subtypes of colorectal cancers exhibit distinct clinicopathological and molecular features

    2016-12-01

    Full Text Available The aim of this research paper is to compare the quality of education delivered at the undergraduate level in the public and private institutions of the Twin Cities (Islamabad and Rawalpindi in Pakistan. Data is collected with the help of questionnaires from 246 students. The data was collected from three public and three private educational institutions of the Twin Cities, and the age of students ranged from 18 to 27 years. The research instrument used in this paper is the independent sample t-test to find the difference between the three private and three public educational institutions selected in Rawalpindi and Islamabad in terms of different variables that are very important in measuring the quality of education. For analysis, Levene’s test was adopted, which reflects the variations in educational quality with respect to academic staff availability in the twin cities. The differences in close supervision of students by academic staff between public and private sector educational institutions were also analysed, and the results reflected a difference between private and public educational institutions with respect to close supervision of students. The results also highlighted the factors that are involved in higher performance of students in private institutes as compared to that of students in public institutes. These factors can be implemented in the public sector to increase student performance.

    Although there is a relationship between DNA repair deficiency and temozolomide (TMZ) resistance in glioblastoma (GBM), it remains unclear which molecule is associated with GBM recurrence. We isolated three TMZ-resistant human GBM cell lines and examined the expression of O6-methylguanine-DNA methyltransferase (MGMT) and mismatch repair (MMR) components. We used immunohistochemical analysis to compare MutL homolog 1 (MLH1), postmeiotic segregation increased 2 (PMS2) and MGMT expression in primary and recurrent GBM specimens obtained from GBM patients during TMZ treatment. We found a reduction in MLH1 expression and a subsequent reduction in PMS2 protein levels in TMZ-resistant cells. Furthermore, MLH1 or PMS2 knockdown confered TMZ resistance. In recurrent GBM tumours, the expression of MLH1 and PMS2 was reduced when compared to primary tumours.

    2017-01-01

    Abstract Aberrant formation of interstitial telomeric sequences (ITSs) promotes genome instabilities. However, it is unclear how aberrant ITS formation is suppressed in human cells. Here, we report that MLH1, a key protein involved in mismatch repair (MMR), suppresses telomeric sequence insertion (TSI) at intra-chromosomal regions. The frequency of TSI can be elevated by double-strand break (DSB) inducer and abolished by ATM/ATR inhibition. Suppression of TSI requires MLH1 recruitment to DSBs, indicating that MLH1's role in DSB response/repair is important for suppressing TSI. Moreover, TSI requires telomerase activity but is independent of the functional status of p53 and Rb. Lastly, we show that TSI is associated with chromosome instabilities including chromosome loss, micronuclei formation and chromosome breakage that are further elevated by replication stress. Our studies uncover a novel link between MLH1, telomerase, telomere and genome stability. PMID:28180301

    Background & Aims Lynch syndrome patients have DNA mismatch repair deficiency and up to 80% life-time risk of colorectal cancer. Screening of mutation carriers reduces colorectal cancer incidence and mortality. Selection for constitutional mutation testing relies on family history (Amsterdam and Bethesda Guidelines) and tumour derived biomarkers. Initial biomarker analysis uses mismatch repair protein immunohistochemistry and microsatellite instability. Abnormalities in either identify mismatch repair deficiency but do not differentiate sporadic epigenetic defects, due to MLH1 promoter region methylation (13% of CRCs) from Lynch Syndrome (4% of CRCs). A diagnostic biomarker capable of making this distinction would be valuable. This study compared two biomarkers in tumours with mismatch repair deficiency; quantification of methylation of the MLH1 promoter region using a novel assay and BRAF c.1799T>A, p.(Val600Glu) mutation status in the identification of constitutional mutations. Methods Tumour DNA was extracted (FFPE tissue) and pyrosequencing used to test for MLH1 promoter methylation and presence of the BRAF c.1799T>A, p.(Val600Glu) mutation 71 CRCs from individuals with pathogenic MLH1 mutations and 73 CRCs with sporadic MLH1 loss. Specificity and sensitivity was compared. Findings Unmethylated MLH1 promoter: sensitivity 94.4% (95% CI 86.2–98.4%), specificity 87.7% (95% CI 77.9–94.2%), Wild-type BRAF (codon 600): sensitivity 65.8% (95% CI 53.7–76.5%), specificity 98.6% (95% CI 92.4–100.0%) for the identification of those with pathogenic MLH1 mutations. Conclusions Quantitative MLH1 promoter region methylation using pyrosequencing is superior to BRAF codon 600 mutation status in identifying constitutional mutations in mismatch repair deficient tumours.

    Programmed death-ligand 1 (PD-1/PD-L1) inhibition therapy demonstrates potential as a future treatment for esophageal cancer. Mismatch repair status and tumor PD-L1 expression are the candidate predictive biomarkers for response to this therapy. In colorectal cancer, mismatch repair-deficient tumors are associated with improved survival, although they are not sensitive to 5-fluorouracil-based chemotherapy. The purpose of the present study was to investigate the association between MutL homolog 1 (MLH1) expression and prognosis, response to therapy and PD-L1 expression in esophageal cancer. Immunohistochemistry was used to evaluate MLH1 and PD-L1 expression in 251 resected specimens. Of the specimens, 30.3% exhibited low MLH1 expression and 15.5% exhibited high PD-L1 expression. The 5-year overall survival rates for the high MLH1 expression group and the low MLH1 expression group were 51.3 and 55.6%, respectively (P=0.5260). The responder ratio was 45.7% in the high MLH1 expression group and 15.4% in the low MLH1 expression group (PMLH1 expression group (P=0.0064) and 25.0% in the low MLH1 expression group. MLH1 expression may be a predictive factor for the response to preoperative therapy in esophageal cancer, and esophageal cancer with low MLH1 expression may have a mechanism that assists in promoting tumor PD-L1 expression.

    Huntington's disease (HD) is a dominantly inherited neurodegenerative disease caused by an expanded CAG repeat in HTT. Many clinical characteristics of HD such as age at motor onset are determined largely by the size of HTT CAG repeat. However, emerging evidence strongly supports a role for other genetic factors in modifying the disease pathogenesis driven by mutant huntingtin. A recent genome-wide association analysis to discover genetic modifiers of HD onset age provided initial evidence for modifier loci on chromosomes 8 and 15 and suggestive evidence for a locus on chromosome 3. Here, genotyping of candidate single nucleotide polymorphisms in a cohort of 3,314 additional HD subjects yields independent confirmation of the former two loci and moves the third to genome-wide significance at MLH1, a locus whose mouse orthologue modifies CAG length-dependent phenotypes in a Htt-knock-in mouse model of HD. Both quantitative and dichotomous association analyses implicate a functional variant on ∼32% of chromosomes with the beneficial modifier effect that delays HD motor onset by 0.7 years/allele. Genomic DNA capture and sequencing of a modifier haplotype localize the functional variation to a 78 kb region spanning the 3'end of MLH1 and the 5'end of the neighboring LRRFIP2, and marked by an isoleucine-valine missense variant in MLH1. Analysis of expression Quantitative Trait Loci (eQTLs) provides modest support for altered regulation of MLH1 and LRRFIP2, raising the possibility that the modifier affects regulation of both genes. Finally, polygenic modification score and heritability analyses suggest the existence of additional genetic modifiers, supporting expanded, comprehensive genetic analysis of larger HD datasets. © The Author 2017.

    Hepatocellular carcinoma (HCC) is a malignant cancer causing deleterious health effect worldwide, especially in China. So far clinical cure rate and long-term survival rate of HCC remains low. Most HCC patients after cancer resection have recurrence or metastasis within 5 years. This study aims to explore the genetic association of mutL homolog 1 ( MLH1 ) polymorphisms with HCC risk and prognosis. Four candidate MLH1 polymorphisms, rs1800734, rs10849, rs3774343 and rs1540354 were studied from a hospital-based case-control study including 1,036 cases (HCC patients) and 1,036 controls (non-HCC patients) in Guangxi, China. All these SNPs interacted with environmental risk factors, such as HBV infection, alcohol intake and smoking in the pathogenesis of HCC. However, only rs1800734 had significant difference between cases and controls. Compared to the AA genotype, patients with AG, GG and AG/GG genotype of rs1800734 had an increased risk of HCC [ORs (95% CI) = 1.217 (1.074∼1.536), 1.745 (1.301∼2.591) and 1.291 (1.126∼1.687)] and a decreased survival time [co-dominant, HR (95% CI) = 1.553 (1.257∼1.920); dominant, HR (95% CI) = 2.207 (1.572∼3.100)]. Furthermore, we found that tumor number, tumor staging, metastasis and rs1800734 were associated with the overall survival of HCC patients by multivariate COX regression analysis. No significant difference was found between the other three MLH1 polymorphisms with HCC risk and prognosis. Our study suggests MLH1 SNP, rs1800734 as a new predictor for poor prognosis of HCC patients.

    Abstract Colorectal cancer (CRC) genome is unstable and different types of instabilities, such as chromosomal instability (CIN) and microsatellite instability (MSI) are thought to reflect distinct cancer initiating mechanisms. Although 85% of sporadic CRC reveal CIN, 15% reveal mismatch repair (MMR) malfunction and MSI, the hallmarks of Lynch syndrome with inherited heterozygous germline mutations in MMR genes. Our study was designed to comprehensively follow genome-wide expression changes and their implications during colon tumorigenesis. We conducted a long-term feeding experiment in the mouse to address expression changes arising in histologically normal colonic mucosa as putative cancer preceding events, and the effect of inherited predisposition (Mlh1+/−) and Western-style diet (WD) on those. During the 21-month experiment, carcinomas developed mainly in WD-fed mice and were evenly distributed between genotypes. Unexpectedly, the heterozygote (B6.129-Mlh1tm1Rak) mice did not show MSI in their CRCs. Instead, both wildtype and heterozygote CRC mice showed a distinct mRNA expression profile and shortage of several chromosomal segregation gene-specific transcripts (Mlh1, Bub1, Mis18a, Tpx2, Rad9a, Pms2, Cenpe, Ncapd3, Odf2 and Dclre1b) in their colon mucosa, as well as an increased mitotic activity and abundant numbers of unbalanced/atypical mitoses in tumours. Our genome-wide expression profiling experiment demonstrates that cancer preceding changes are already seen in histologically normal colon mucosa and that decreased expressions of Mlh1 and other chromosomal segregation genes may form a field-defect in mucosa, which trigger MMR-proficient, chromosomally unstable CRC.

    Missense variants discovered during sequencing of cancer susceptibility genes can be problematic for clinical interpretation. MLH1 K618A, which results from a 2-bp alteration (AAG→GCG) leading to a substitution of lysine to alanine in codon 618, has variously been interpreted as a pathogenic mutation, a variant of unknown significance, and a benign polymorphism. We evaluated the role of MLH1 K618A in predisposition to cancer by genotyping 1512 control subjects to assess its frequency in the general population. We also reviewed the literature concerning MLH1 K618A in families with colorectal cancer. The measured allele frequency of the K618A variant was 0.40%, which is remarkably close to the 0.44% summarized from 2491 control subjects in the literature. K618A was over-represented in families with suspected Lynch syndrome. In 1366 families, the allele frequency was 0.88% (OR = 2.1, 95% CI = 1.3 to 3.5; P = 0.006). In studies of sporadic cancers of the type associated with Lynch syndrome, K618A was over-represented in 1742 cases (allele frequency of 0.83) (OR = 2.0, 95% CI = 1.2 to 3.2; P = 0.008). We conclude that MLH1 K618A is not a fully penetrant Lynch syndrome mutation, although it is not without effect, appearing to increase the risk of Lynch syndrome-associated tumors approximately twofold. Our systematic assessment approach may be useful for variants in other genes. PMID:22426235

    Lynch syndrome (LS) is an autosomal-dominant inherited disorder mainly caused by a germline mutation in the DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6, and PMS2) and is associated with increased risk for various cancers, particularly colorectal cancer and endometrial cancer (EC). Women with LS account for 2% to 6% of EC patients; it is clinically important to identify LS in such individuals for predicting and/or preventing additional LS-associated cancers. PMS2 germline mutation (PMS2-LS) is the rarest contribution to LS etiology among the 4 LS-associated MMR germline mutations, and its detection is complicated. Therefore, prudent screening for PMS2-LS is important as it leads to an efficient LS identification strategy. Immunohistochemistry is recommended as a screening method for LS in EC. Isolated loss of PMS2 (IL-PMS2) expression is caused not only by PMS2-LS but also by MLH1 germline mutation or MLH1 promoter hypermethylation (MLH-PHM). This study aimed to determine the association between MLH1-PHM and IL-PMS2 to avoid inappropriate genetic analysis. We performed MLH1 methylation analysis and MLH1/PMS2 germline mutation testing on the IL-PMS2 cases. By performing MMR-immunohistochemistry on 360 unselected ECs, we could select 8 (2.2%) cases as IL-PMS2. Heterogenous MLH1 staining and MLH1-PHM were detected in 4 of 8 (50%) IL-PMS2 tumors. Of the 5 IL-PMS2 patients who underwent genetic analysis, 1 had PMS2 germline mutation with normal MLH1 expression (without MLH1-PHM), and no MLH1 germline mutation was detected. We suggest that MLH1 promoter methylation analysis for IL-PMS2 EC should be performed to exclude sporadic cases before further PMS2 genetic testing.

    Traditional Chinese medicine formulates treatment according to body constitution (BC) differentiation. Different constitutions have specific metabolic characteristics and different susceptibility to certain diseases. This study aimed to assess the characteristic genes of gan-shen Yin deficiency constitution in different diseases. Fifty primary liver cancer (PLC) patients, 94 hypertension (HBP) patients, and 100 diabetes mellitus (DM) patients were enrolled and classified into gan-shen Yin deficiency group and non-gan-shen Yin deficiency group according to the body constitution questionnaire to assess the clinical manifestation of patients. The mRNA expressions of 17 genes in PLC patients with gan-shen Yin deficiency were different from those without gan-shen Yin deficiency. However, considering all patients with PLC, HBP, and DM, only MLH3 was significantly lower in gan-shen Yin deficiency group than that in non-gen-shen Yin deficiency. By ROC analysis, the relationship between MLH3 and gan-shen Yin deficiency constitution was confirmed. Treatment of MLH3 (-/- and -/+) mice with Liuweidihuang wan, classical prescriptions for Yin deficiency, partly ameliorates the body constitution of Yin deficiency in MLH3 (-/+) mice, but not in MLH3 (-/-) mice. MLH3 might be one of material bases of gan-shen Yin deficiency constitution.

    China's nuclear industry is recently experiencing rapid development, creating a need for research into public perceptions and acceptance of nuclear power. In this paper, we propose a strategy for investigating public perception and acceptance in China, in a continuous and accurate way, and testing the effectiveness of public education in order to find a proper way to improve the perception and acceptance of nuclear energy in China. Questionnaires are conducted separately both before and after public education activities on nuclear energy held in Beijing. Some conclusions and future continuation of this study are also discussed.

    Full Text Available The issue of mixed educational financing is rarely evoked in the literature, although the financial contribution of parents in the public educational system can be significant. This paper presents a comparative analysis of the mixed system and public and private ‘extreme’ systems in terms of economic growth and social disparity. For developing countries and for heterogeneous individuals, the mixed system is widely preferred. For homogeneous agents the public and private systems cannot lead to better economic performance than the mixed system. The public system always reduces social inequality, in contrast to the mixed and private systems, which generate the same level of inequality.

    Full Text Available Background. Lynch Syndrome (LS is characterized by germline mutations in the DNA mismatch repair (MMR genes MLH1, MSH2, MSH6, and PMS2. This syndrome is inherited in an autosomal dominant pattern and is characterized by early onset colorectal cancer (CRC and extracolonic tumors. The aim of this study was to identify mutations in MMR genes in three Mexican patients with LS. Methods. Immunohistochemical analysis was performed as a prescreening method to identify absent protein expression. PCR, Denaturing High Performance Liquid Chromatography (dHPLC, and Sanger sequencing complemented the analysis. Results. Two samples showed the absence of nuclear staining for MLH1 and one sample showed loss of nuclear staining for MSH2. The mutations found in MLH1 gene were c.2103+1G>C in intron 18 and compound heterozygous mutants c.1852_1854delAAG (p.K618del and c.1852_1853delinsGC (p.K618A in exon 16. In the MSH2 gene, we identified mutation c.638dupT (p.L213fs in exon 3. Conclusions. This is the first report of mutations in MMR genes in Mexican patients with LS and these appear to be novel.

    Full Text Available Hereditary NonPolyposis Colorectal Cancer (Lynch syndrome is an autosomal dominant disease caused by germline mutations in a class of genes deputed to maintain genomic integrity during cell replication, mutations result in a generalized genomic instability, particularly evident at microsatellite loci (Microsatellite Instability, MSI. MSI is present in 85–90% of colorectal cancers that occur in Lynch Syndrome. To standardize the molecular diagnosis of MSI, a panel of 5 microsatellite markers was proposed (known as the “Bethesda panel”. Aim of our study is to evaluate if MSI testing with two mononucleotide markers, such as BAT25 and BAT26, was sufficient to identify patients with hMLH1/hMSH2 germline mutations. We tested 105 tumours for MSI using both the Bethesda markers and the two mononucleotide markers BAT25 and BAT26. Moreover, immunohistochemical evaluation of MLH1 and MSH2 proteins was executed on the tumours with at least one unstable microsatellite, whereas germline hMLH1/hMSH2 mutations were searched for all cases showing two or more unstable microsatellites.

    Background: The Slovak Republic joined the European Union (EU on May 1st 2004. The public health system
    of the country is under continuous transition including public health education and training. The aim of the presented paper is to describe and discuss how far the transition of public health education of the country
    went during last time period.

    Methods: Web site review, documentation search and curriculum content analysis were the main methods
    employed within presented paper.

    Results: There are 7 universities offering public health education on bachelor, master and doctoral level.
    Among them 6 could be found in list of accredited universities of the Ministry of Education by Accreditation
    Committee of the Government of the Slovak Republic. The three levels of education are fully harmonized with
    the Bologna principles. The Accreditation Committee of the Government of the Slovak Republic describes very detailed aims of a public health education program including recommended study subjects. Universities add to additional, mostly clinical medicine or hygiene subjects to recommend study subjects leaving likely very
    little time for research at universities.

    Conclusions: Despite large progress further effort is needed to clarify what is public health, what kind of subject should be included in curricula and on introduction of public health research at universities.

    Because of the need for a well-trained public health workforce, professional competencies have been recently revised by the Institute of Medicine and the National Health Educator Competencies Update Project. This study compared the self-identified training needs of public health educators with the updated competencies and assessed employer support for continuing education. A convenience sample of public health educators was recruited from an e-mail list of San Jose State University master of public health alumni. Respondents completed a Web-based survey that elicited information on emerging trends in public health education, training needs, and employer support for continuing education. Concerns about funding cuts and privatization of resources emerged as a theme. Key trends reported were an increase in information technology, the need for policy advocacy skills, and the importance of a lifespan approach to health issues. Primary areas for training were organization development, evaluation, and management. Although most employers were reported to support continuing education, less than two-thirds of respondents were reimbursed for expenses. These findings have implications for both research and practice. Innovative technologies should be developed to address health education professionals' training needs, and emerging themes should be incorporated into curricula for students.

Besides of the historical and sociological sources he pays attention on a few aspects, which - in his opinion - intensified the negative public responses: Chernobyl catastrophe, the coal-lobby influences, the political parties (not only 'green') games during election time, existing of old conventional coal power stations, accessibility of own cheap coal, cost of transformation from communistic to free-market economy, low-level of public pro-ecology thinking and so on. On the other hand the author describes some non-realistic attitudes of society - for example - they accept nuclear medicine while do not agree to develop nuclear power engineering. Finally he presents conclusions, which can change public perception of radiation. (author)

    2013-12-01

    Stephanie Baird Wilkerson, PhD Carol Haden EdD Magnolia Consulting,LLC Education and public outreach (EPO) program developers and providers seeking insights regarding effective practices for evaluating EPO activities programs benefit from understanding why evaluation is critical to the success of EPO activities and programs, what data collection methods are appropriate, and how to effectively communicate and report findings. Based on our extensive experience evaluating EPO programs, we will share lessons learned and examples of how these practices play out in actual evaluation studies. EPO program developers, providers, and evaluators must consider several factors that influence which evaluation designs and data collection methods will be most appropriate, given the nature of EPO programs. Effective evaluation practices of EPO programs take into account a program's phase of development, duration, and budget as well as a program's intended outcomes. EPO programs that are just beginning development will have different evaluation needs and priorities than will well-established programs. Effective evaluation practices consider the 'life' of a program with an evaluation design that supports a program's growth through various phases including development, revision and refinement, and completion. It would be premature and inappropriate to expect the attainment of longer-term outcomes of activities during program development phases or early stages of implementation. During program development, EPO providers should clearly define program outcomes that are feasible and appropriate given a program's scope and expected reach. In many respects, this directly relates to the amount of time, or duration, intended audiences participate in EPO programs. As program duration increases so does the likelihood that the program can achieve longer-term outcomes. When choosing which outcomes are reasonable to impact and measure, program duration should be considered. Effective evaluation

Although the global economic crisis was the reason for disinvestment into ICT in 2009 there is expected that ICT will generate almost 5.8 million new jobs in Europe till year 2013 and they have to be saturated also by adequately qualified ICT specialists.This contribution presents the research in the progress focused on the tertiary education system in the Czech Republic. We are predicting trends in education and especially in ICT education in Europe and in the Czech Republic as well for next ten years. We can expect that future ten years period will be critical not only for the Czech tertiary education system, but also for the Czech Republic because number of ICT students will be decreasing and number of ICT specialist demanded by labor market will be increasing. From macroeconomic point of view we can expect that also state subventions into state governed tertiary education system will decrease in the whole Europe.Some recommendations, proposals and forecasts for further development of education system are presented at the end of this contribution.

    Continuing education of health care providers plays an important role in producing a health work force that is efficient and effective. In India public health education has primarily relied on conventional methods of training. However, such methods have limitations in equipping the health workforce of a vast and varied country like India. This paper analyzes the current status of distance education in public health and lists the various courses that are presently available in India through the distance education mode. Presently 25 institutions in India are offering 69 courses in various domains of public health through distance education. The providers of these programs comprised both government and private educational institutions. This paper also points out the role and importance of various stakeholders in the design and delivery of distance education programs in public health and raises key areas that need attention in the governance of such programs. It urges the use of digital technology in the delivery of distance education programs and points out how distance education that is designed and delivered using the latest technology could address the current gap in training human resources for health in India.

    A competent and motivated health workforce is indispensable to achieve the best health outcomes possible through given available resources and circumstances. However, apart from the shortages and unequal distribution, the workforce has fallen short of responding to the public health challenges of 21 st century also because of primarily the traditional training of health professionals. Although, health professionals have made enormous contributions to health and development over the past century, the 20 th century educational strategies are unfit to tackle 21 st century challenges. One of the key recommendations of the Lancet Commission on Education of Health Professionals is to improve health through reforms of professional education by establishing networks and partnerships which takes advantage of information and communication linkages. The primary goal of this manuscript is to highlight the potential of networks and partnerships in advancing the agenda of educational reforms to revitalize public health education in India. It outlines the current status and expanding scope of public health education in India, existing networks of public health professionals and public health education institutions in the country, and opportunities, advantages and challenges for such networks. Although, we have networks of individuals and institutions in the country, there potential to bring about change has still not being utilized fully and effectively. Immediate collaborative efforts could be directed towards designing and adaptation of competency driven curriculum frameworks suitable of addressing public health challenges of 21 st century, shifting the current focus of curriculum to multidisciplinary public health outlook, developing accreditation mechanisms for both the programs and institutions, engaging in creating job opportunities and designing career pathways for public health professionals in public and private sector. These efforts could certainly be facilitated

At the time when global focus on public health is increasing, a severe shortage of public health professionals is projected. A strong educational framework is imperative to ensure the capacity and capability of the worldwide public health workforce for the future. Frenk and Chen (2011 comment that academic public health has done far less than medicine or nursing to examine its pedagogy. The goal of this study is to examine the literature pertaining to the education of public health professionals in order to document the extent to which those preparing public health professionals think about what they teach, how they teach, and what the results of the instruction are. The specific objectives are to (1 identify relevant peer reviewed literature, (2 analyze that literature for content, (3 characterize the literature according to type of methodology, and (4 draw conclusions and implications to enhance future pedagogical efforts. The study searched three bibliographic sources for articles written in English between 2000-2012. The search of PubMed, Scopus, Education Full Text identified 576 unique articles. The articles were analyzed according to ten content themes and four format categories. The conclusions are that those teaching public health professionals devote considerable thought to what and how they teach, although original research and evaluation studies are fewer than descriptive reports of courses, programs and curricula. A journal devoted specifically to articles pertaining to education of public health professionals will encourage academicians to write articles sharing approaches to educating the public health workforce.

    Prior to 2001, the Department of Energy (DOE) sponsored limited tours of the Hanford Site for the public, but discontinued the program after the 9/11 terrorist attacks on the U.S. In 2003, DOE's Richland Operations Office (DOE-RL) requested the site's prime contractor to reinstate the public tour program starting in 2004 under strict controls and security requirements. The planning involved a collaborative effort among the security, safety and communications departments of DOE-RL and the site's contracting companies. This paper describes the evolution of, and enhancements to, Hanford's public tours, including the addition of a separate tour program for the B Reactor, the first full-scale nuclear reactor in the world. Topics included in the discussion include the history and growth of the tour program, associated costs, and visitor surveys and assessments.

    The establishment and continuing development of a sufficient and competent public health workforce is fundamental for the planning, implementation, evaluation, effect and ethical validity of public health strategies and policies and, thus, for the development of the population's health and the cost-effectiveness of health and public health systems and interventions. Professional public health strategy-making demands a background of a comprehensive multi-disciplinary curriculum including mutually, dynamically coherent competences - not least, competences in sociology and other behavioural sciences and their interaction with, for example, epidemiology, biostatistics, qualitative methods and health promotion and disease prevention. The size of schools and university departments of public health varies, and smaller entities may run into problems if seeking to meet the comprehensive curriculum challenge entirely by use of in-house resources. This commentary discusses the relevance and strength of establishing comprehensive curriculum development networks between schools and university departments of public health, as one means to meet the comprehensiveness challenge. This commentary attempts to consider a two-stage strategy to develop complete curricula at the bachelor and master's as well as PhD levels.
