  8. Attitudes of second language students towards self-editing their own written texts

    Directory of Open Access Journals (Sweden)

    Daniel Kasule

    2010-05-01

    Full Text Available Recognizing students’ deliberate e!orts to minimize errors in their written texts is valuable in seeing them as responsible active agents in text creation. This paper reports on a brief survey of the attitudes towards self-editing of seventy university students using a questionnaire and class discussion. The context of the study is characterized by its emphasis on evaluating the finished written product. Findings show that students appreciate the role of self-editing in minimizing errors in their texts and that it helps in eventually producing well-written texts. Conceptualizing writing as discourse and therefore as social practice leads to an understanding of writers as socially-situated actors; repositions the student writer as an active agent in text creation; and is central to student-centred pedagogy. We recommend the recognition of self-editing as a vital element in the writing process and that additional error detection mechanisms namely peers, the lecturer, and the computer, increase student autonomy.

  14. Peer-editing Practice in the Writing Classroom: Benefits and Drawbacks

    Directory of Open Access Journals (Sweden)

    Ann Rosnida Md. Deni

    2011-01-01

    Full Text Available Small scale studies have shown that peer-editing is beneficial to students as it increases their awareness of the complex process of writing, it improves their knowledge of and skills in writing and helps them become more autonomous in learning. Teachers too may benefit from peer-editing as this practice discloses invaluable information on students’ writing weaknesses and strengths: and teachers’ teaching effectiveness. This is a small scale study conducted on fifteen first-year degree students majoring in Tourism to view the usefulness of peer-editing practice in enhancing their writing skills. Retrospective notes were taken to record students’ receptiveness and reaction towards peer editing practice: students writing samples and peer- editing questionnaires were analyzed to view students’ revisions and comments; and an open— ended questionnaire was distributed to identify students perceptions of peer—editing practice in the writing classroom. Analysis of data gathered revealed that peer-editing practice benefitted both the teacher and most of her students as it exposed important information that could improve her teaching of writing and her students’ writing practices. Data analysis also. however, discloses that peer-editing practice may have adverse effects on students’ motivation and improvement in writing if they are not deployed properly.

  15. Inconsistent reports of risk behavior among Brazilian middle school students: National School Based Survey of Adolescent Health (PeNSE 2009/2012

    Directory of Open Access Journals (Sweden)

    Dandara de Oliveira Ramos

    Full Text Available Abstract: This study assessed the consistency of self-reports of risk behavior (overall and within four specific domains: alcohol use, tobacco use, drug use, and sexual activity in two editions of the Brazilian National School Based Survey of Adolescent Health (PeNSE: 2009 and 2012. The overall proportion of cases with at least one inconsistent response in the two editions was 11.7% (2.7% on the alcohol items, 2.1% for drug use, 4.3% for cigarette use, 3% for sexual activity and 22.7% (12.8% on alcohol items, 2.5% for drug use, 4.3% for cigarette use, 4.1% for sexual activity, respectively. Such inconsistency was more prevalent among males, delayed students, those who reported having experimented with drugs, and those who did not have a cellphone. Because inconsistent responses were more prevalent among the students who claimed to have engaged in risky activities, removing inconsistent responders affected the estimated prevalence of all risk behaviors in both editions of the survey. This study supports the importance of performing consistency checks of self-report surveys, following the growing body of literature on this topic.

  19. Peer editing: a strategic source in EFL students’ writing process

    Directory of Open Access Journals (Sweden)

    Nubia Mercedes Díaz Galvis

    2011-06-01

    Full Text Available This article reports on a research project focused on peer editing as a pedagogical tool to promote collaborative assessment in the EFL writing process. With teachers overstretched in the Bogotá public school system, a method needed to be found that would allow students to receive much needed feedback without overtaxing the teachers` resources. Peer editing, a phenomenon that often occurs naturally within the classroom, was therefore systematically implemented as a solution to the stated problem. The main aims of this study, conducted with a group of ninth grade student at a public school in Bogotá, were to determine the role of peer editing in the writing process and to characterize the relationships built when students corrected each others writings. The instruments used for collecting data were field notes, video recordings and students’ artifacts. The results showed that when students were engaged in peer editing sessions they created zones of proximal development in which high achiever students provided linguistic scaffolding and empowered low achievers. It was also found that students used thinking strategies such as noticing and explaining when they identified errors related to the formal aspects of the language.

  15. Does atlas-based autosegmentation of neck levels require subsequent manual contour editing to avoid risk of severe target underdosage? A dosimetric analysis

    International Nuclear Information System (INIS)

    Voet, Peter W.J.; Dirkx, Maarten L.P.; Teguh, David N.; Hoogeman, Mischa S.; Levendag, Peter C.; Heijmen, Ben J.M.

    2011-01-01

    Background and purpose: To investigate the dosimetric impact of not editing auto-contours of the elective neck and organs at risk (OAR), generated with atlas-based autosegmentation (ABAS) (Elekta software) for head and neck cancer patients. Materials and methods: For nine patients ABAS auto-contours and auto-contours edited by two observers were available. Based on the non-edited auto-contours clinically acceptable IMRT plans were constructed (designated 'ABAS plans'). These plans were then evaluated for the two edited structure sets, by quantifying the percentage of the neck-PTV receiving more than 95% of the prescribed dose (V 95 ) and the near-minimum dose (D 99 ) in the neck PTV. Dice coefficients and mean contour distances were calculated to quantify the similarity of ABAS auto-contours with the structure sets edited by observer 1 and observer 2. To study the dosimetric importance of editing OAR auto-contours a new IMRT plan was generated for each patient-observer combination, based on the observer's edited CTV and the non-edited salivary gland auto-contours. For each plan mean doses for the non-edited glands were compared with doses for the same glands edited by the observer. Results: For both observers, edited neck CTVs were larger than ABAS auto-contours (p ≤ 0.04), by a mean of 8.7%. When evaluating ABAS plans on the PTVs of the edited structure sets, V 95 reduced by 7.2% ± 5.4% (1 SD) (p 99 was 14.2 Gy (range 1-54 Gy). Even for Dice coefficients >0.8 and mean contour distances 99 up to 11 Gy were observed. For treatment plans based on observer PTVs and non-edited auto-contoured salivary glands, the mean doses in the edited glands differed by only -0.6 Gy ± 1.0 Gy (p = 0.06). Conclusions: Editing of auto-contoured neck CTVs generated by ABAS is required to avoid large underdosages in target volumes. Often used similarity measures for evaluation of auto-contouring algorithms, such as dice coefficients, do not predict well for expected PTV underdose

    The reliable evaluation of occupational therapy students completing practice education placements along with provision of appropriate feedback is critical for both students and for universities from a quality assurance perspective. This study describes the development of a comment bank for use with an online version of the Student Practice Evaluation Form-Revised Edition (SPEF-R Online) and investigates its reliability. A preliminary bank of 109 individual comments (based on previous students' placement performance) was developed via five stages. These comments reflected all 11 SPEF-R domains. A purpose-designed online survey was used to examine the reliability of the comment bank. A total of 37 practice educators returned surveys, 31 of which were fully completed. Participants were asked to rate each individual comment using the five-point SPEF-R rating scale. One hundred and two of 109 comments demonstrated satisfactory agreement with their respective default ratings that were determined by the development team. At each domain level, the intra-class correlation coefficients (ranging between 0.86 and 0.96) also demonstrated good to excellent inter-rater reliability. There were only seven items that required rewording prior to inclusion in the final SPEF-R Online comment bank. The development of the SPEF-R Online comment bank offers a source of reliable comments (consistent with the SPEF-R rating scale across different domains) and aims to assist practice educators in providing reliable and timely feedback to students in a user-friendly manner. © 2014 Occupational Therapy Australia.

    Stott, Peter [JET, UK (United Kingdom)

    1998-10-01

    The first edition of John Wesson's book on tokamaks, published in 1987, established itself as essential reading for researchers in the field of magnetic confinement fusion: it was an excellent introduction for students to tokamak physics and also a valuable reference work for the more experienced. The second edition, published in 1997, has been completely rewritten and substantially enlarged (680 pages compared with 300). The new edition maintains the aim of providing a simple introduction to basic tokamak physics, but also includes discussion of the substantial advances in fusion research during the past decade. The new book, like its predecessor, is well written and commendable for its clarity and accuracy. In fact many of the chapters are written by a series of co-authors bringing the benefits of a wide range of expertise but, by careful editing, Wesson has maintained a uniformity of style and presentation. The chapter headings and coverage for the most part remain the same - but are expanded considerably and brought up to date. The most substantial change is that the single concluding chapter in the first edition on 'Experiments' has been replaced by three chapters: 'Tokamak experiments' which deals with some of the earlier key experiments plus a selection of recent small and medium-sized devices, 'Large experiments' which gives an excellent summary of the main results from the four large tokamaks - TFTR, JET, JT60/JT60U and DIII-D, and 'The future' which gives a very short (possibly too short in my opinion) account of reactors and ITER. This is an excellent book, which I strongly recommend should have a place - on the desk rather than in the bookshelf - of researchers in magnetic confinement fusion. (book review)

    Full Text Available This study set out to investigate the effect of peer- editing as a metacognitive strategy on the development of writing. It was hypothesized that peer-editing could be used to raise grammatical and compositional awareness of the learners. Forty pre-intermediate sophomores at Islamic Azad University-Tabriz Branch participated in the study, taking the course Writing I. To warrant the initial homogeneity of the groups, a nonequivalent pretest –posttest design was selected and the groups were randomly determined as the control and the experimental groups, each with twenty subjects.  The treatment following the pretest involved a three-phase planning procedure including: consciousness awareness via error recognition activities, error categorizing activities, and self/peer editing. Statistical analysis of the post-test composition did not reveal any significant difference between the two groups.  It seems that peer-editing entails a firm grammatical foundation which needs to be formed early in the process of language learning. The results underscore the need to reorient the method of teaching grammar at university level in a way to accommodate a task-based approach to cognitive and metacognitive strategies-based training.

    Full Text Available Communication also means having to sort out the problems involved in learning a foreign language, especially with regards to production rather than reception. These learning strategies or skills can also be applied to translation teaching methodology, where students put in practice their risk taking, avoidance, reduction and/ or compensatory strategies in getting the message across. We acknowledge translation as a writing task constrained by the source text. In addition, the translation and the writing cycles have in common a generation stage and a revision stage where grammatical, lexical and stylistic correctness is assessed. Somewhere in the middle between translation and writing skills lies MT (Machine Translation post-editing that involves correcting the raw MT output with the aim of providing a quality text according to the intended purpose. Our research is intended to test the suitability of MT post-editing as an activity to promote error correction and, subsequently, to enhance written production in second and foreign language teaching.

  11. Fan edits and the legacy of The Phantom Edit

    Directory of Open Access Journals (Sweden)

    Joshua Wille

    2014-09-01

    Full Text Available A fan edit can generally be defined as an alternative version of a film or television text created by a fan. It offers a different viewing experience, much as a song remix offers a different listening experience. The contemporary wave of fan edits has emerged during the remix zeitgeist of digital media and at a time when digital video editing technology has become more affordable and popular. The increasing number of alternative versions of films and the works of revisionist Hollywood filmmakers such as George Lucas have contributed to a greater public understanding of cinema as a fluid medium instead of one that exists in a fixed form. The Phantom Edit (2000, a seminal fan edit based on Lucas's Star Wars Episode I: The Phantom Menace (1999, inspired new ranks of fan editors. However, critics have misunderstood fan edits as merely the work of disgruntled fans. In order to provide a critical and historical basis for studies in fan editing as a creative practice, I examine previous interpretations of fan edits in the context of relevant contemporary works, and I use an annotated chronology of The Phantom Edit to trace its influence on subsequent fan editing communities and uncover their relationship with intellectual property disputes.

    Adenosine-to-inosine (A-to-I) RNA editing, a process mediated by adenosine deaminases that act on the RNA (ADAR) gene family, is a recently discovered epigenetic modification dysregulated in human cancers. However, the clinical significance and the functional role of RNA editing in colorectal cancer (CRC) remain unclear. We have systematically and comprehensively investigated the significance of the expression status of ADAR1 and of the RNA editing levels of antizyme inhibitor 1 (AZIN1), one of the most frequently edited genes in cancers, in 392 colorectal tissues from multiple independent CRC patient cohorts. Both ADAR1 expression and AZIN1 RNA editing levels were significantly elevated in CRC tissues when compared with corresponding normal mucosa. High levels of AZIN1 RNA editing emerged as a prognostic factor for overall survival and disease-free survival and were an independent risk factor for lymph node and distant metastasis. Furthermore, elevated AZIN1 editing identified high-risk stage II CRC patients. Mechanistically, edited AZIN1 enhances stemness and appears to drive the metastatic processes. We have demonstrated that edited AZIN1 functions as an oncogene and a potential therapeutic target in CRC. Moreover, AZIN1 RNA editing status could be used as a clinically relevant prognostic indicator in CRC patients.

    Full Text Available Objective: To learn the social representations of ergonomic risk prepared ​​by dental students. Methodology: This exploratory study, subsidized the Theory of Social Representations, with 64 dental students of an educational institution, by means of interviews. The data were processed in Alceste4.8 and lexical analysis done by the descending hierarchical classification. Results: In two categories: knowledge about exposure to ergonomic risk end attitude of students on preventing and treating injuries caused by repetitive motion. For students, the ergonomic risk is related to the attitude in the dental office. Conclusion: Prevention of ergonomic risk for dental students has not been incorporated as a set of necessary measures for their health and the patients, to prevent ergonomic hazards that can result in harm to the patient caused by work-related musculoskeletal disorder, which is reflected in a lower quality practice.

    New Perspectives on Technical Editing by Avon J. Murphy (ed.) ISBN : 978-0895033949 (2010) Baywood Publishing Company Inc, Hardcover, 210 pages, 35.5 GBP This book presents a collection of 10 chapters dealing with diverse aspects of technical editing (ie, editorial planning, and analysis and structural changes made to other people's technological documents): research in technical editing, trends and teaching of technical editing, copyediting, and technical journal editing. The role and function of the modern journal and book editor is also dealt with in detail. Each chapter is written by an expert in the field: senior editors, university professors in technical communication, technical writers and linguists. The ever-evolving role of the editor is clearly elucidated in several historical reviews, and in the descriptions of the expectations for the future. A very striking aspect of this book is its extensive collection of bibliographic resources: every chapter lists dozens of very useful references, and the closing chapter, and annotated bibliography, contain many not so well known references, and are most useful. All in all, the book is a treasure trove listing more than 400 references, in addition to numerous webpage URLs embedded in the texts. The book is designed to help the reader to understand current practices and norms in technical editing, and to help to take action in editing as well as in teaching and educating would-be editors. The audience for this book thus includes editors and teachers, but also writers, researchers and students. A deep reading of this book will result in a better understanding of the difference between full technical editing and its much narrower component so well known as copyediting, and will convince any prospective editor that editing should not be undertaken if the people involved do not master the art of precision and accuracy in technical (as well as in human) communication, do not possess the technical know how and computer

    Site-directed RNA editing (SDRE) is a general strategy for making targeted base changes in RNA molecules. Although the approach is relatively new, several groups, including our own, have been working on its development. The basic strategy has been to couple the catalytic domain of an adenosine (A) to inosine (I) RNA editing enzyme to a guide RNA that is used for targeting. Although highly efficient on-target editing has been reported, off-target events have not been rigorously quantified. In this report we target premature termination codons (PTCs) in messages encoding both a fluorescent reporter protein and the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein transiently transfected into human epithelial cells. We demonstrate that while on-target editing is efficient, off-target editing is extensive, both within the targeted message and across the entire transcriptome of the transfected cells. By redirecting the editing enzymes from the cytoplasm to the nucleus, off-target editing is reduced without compromising the on-target editing efficiency. The addition of the E488Q mutation to the editing enzymes, a common strategy for increasing on-target editing efficiency, causes a tremendous increase in off-target editing. These results underscore the need to reduce promiscuity in current approaches to SDRE.

    Klein, Jennifer; Cornell, Dewey; Konold, Timothy

    2012-09-01

    This study examined whether characteristics of a positive school climate were associated with lower student risk behavior in a sample of 3,687 high school students who completed the School Climate Bullying Survey and questions about risk behavior from the Youth Risk Behavior Surveillance Survey (YRBS). Confirmatory factor analyses established fit for 20 items with three hypothesized school climate scales measuring (1) prevalence of bullying and teasing; (2) aggressive attitudes; and (3) student willingness to seek help. Structural equation modeling established the relationship of these measures with student reports of risk behavior. Multigroup analyses identified differential effects across gender and race. A positive school climate could be an important protective factor in preventing student risk behavior.

    The suicide risk among young adults is related to multiple factors; therefore, it is difficult to predict and prevent suicidal behavior. We conducted the present study to reveal the most important factors relating to suicidal ideation in Japanese university students with major depressive episodes (MDEs) of major depressive disorder (MDD). The subjects were 30 Japanese university students who had MDEs of MDD, and were aged between 18 and 26 years old. They were divided into two groups - without suicide risk group (n=15), and with suicide risk group (n=15) - based on the results of the Mini-International Neuropsychiatric Interview. Additionally, healthy controls were recruited from the same population (n=15). All subjects completed the self-assessment scales including the Beck Depression Inventory 2nd edition (BDI-II), the Beck Hopelessness Scale (BHS), Rosenberg's Self-Esteem Scale (RSES), and SF-36v2™ (The Medical Outcomes Study 36-item short-form health survey version 2), and they were all administered a battery of neuropsychological tests. The RSES score of the suicide risk group was significantly lower than the RSES score of the without suicide risk group, whereas the BDI-II score and the BHS score were not significantly different between the two groups. The mean social functioning score on the SF-36v2 of the with suicide risk group was significantly lower than that of the without suicide risk group. The individual's self-esteem and social functioning may play an important role in suicide risk among young adults with MDEs of MDD.

    2004-09-01

    Mathematical methods are essential tools for all physical scientists. This second edition provides a comprehensive tour of the mathematical knowledge and techniques that are needed by students in this area. In contrast to more traditional textbooks, all the material is presented in the form of problems. Within these problems the basic mathematical theory and its physical applications are well integrated. The mathematical insights that the student acquires are therefore driven by their physical insight. Topics that are covered include vector calculus, linear algebra, Fourier analysis, scale analysis, complex integration, Green's functions, normal modes, tensor calculus, and perturbation theory. The second edition contains new chapters on dimensional analysis, variational calculus, and the asymptotic evaluation of integrals. This book can be used by undergraduates, and lower-level graduate students in the physical sciences. It can serve as a stand-alone text, or as a source of problems and examples to complement other textbooks. All the material is presented in the form of problems Mathematical insights are gained by getting the reader to develop answers themselves Many applications of the mathematics are given

    Cardiovascular disease (CVD) is responsible for more than half of all deaths in the European region. The aim of the study was to compare body composition, blood pressure, total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C), family history, activity behaviors, and the 10-year risk of having a heart attack between 166 university students (21.62 ± 2.59 yrs) from Utah (USA) and 198 students (22.11 ± 2.51 yrs) from Hungary. Ninety-two percent of the Hungarian students and 100% of the Utah students had an estimated 10-year Framingham risk score of 1% or less. The high prevalence of low risk was primarily due to the young age of study participants, healthy body composition and non-smoking behavior. Hungarians who had higher 10-year risk of heart attack had significantly higher waist hip ratio (WHR), TC, diastolic blood pressure (DBP) and were smokers compared to those Hungarians with lower risk. The self-reported physical activity levels between the two groups of students were not different. In conclusion the young men and women who participated in this study were, for the most part healthy; however the smoking habits and the lower physical activity of the Hungarian students likely elevated their risk of CVD.

    1999-12-01

    This edition is identical in format and content to the 1996 edition, now sold as the "library edition", except that the names and information for elements 104-109 have been updated. My earlier review still applies; a page-by-page comparison found this edition identical to the first except as noted in the previous sentence. The major revision has been in size and price. The 50% price reduction is welcome, but the format was not changed when the size was reduced, and the resulting 9-point font puts readers at risk of eyestrain. I would like to correct one of the criticisms in my earlier review There is excellent discussion of the industrial uses of each element, as well as its most common source minerals. The more economically important elements are given extensive discussions, detailing industrial uses of the element and its compounds. However, biological activity is given spotty coverage. There is no mention - under "iron" or elsewhere - of the central biological role of iron in oxygen transport or of magnesium in photosynthesis. When coverage appears it is not bad: the roles of calcium in vertebrate and invertebrate skeletons, of fluorine in reducing tooth decay by changing hydroxyapatite to fluorapatite, and of cobalt in vitamin B12 are discussed. While information on transuranium elements has been updated, there has been no attempt to correct several minor errors in spelling, placement, or even information. On page 14 the 1s subshell appears as part of the L (n = 2) shell, and upon the electrolysis of molten sodium chloride on page 54, "sodium collects atthe cathode, and chloride [sic] at...the anode."

    Natural disaster loss is on the rise, and the vulnerability of the human and physical environment to the violent forces of nature is increasing. In many parts of the world, disasters caused by natural hazards such as earthquakes, floods, landslides, drought, wildfires, intense windstorms, tsunami, and volcanic eruptions have caused the loss of human lives, injury, homelessness, and the destruction of economic and social infrastructure. Over the last few years, there has been an increase in the occurrence, severity, and intensity of disasters, culminating with the devastating tsunami of 26 December 2004 in South East Asia.Natural hazards are often unexpected or uncontrollable natural events of varying magnitude. Understanding their mechanisms and assessing their distribution in time and space are necessary for refining risk mitigation measures. This second edition of Natural Hazards, (following a first edition published in 1991 by Cambridge University Press), written by Edward Bryant, associate dean of science at Wollongong University, Australia, grapples with this crucial issue, aspects of hazard prediction, and other issues. The book presents a comprehensive analysis of different categories of hazards of climatic and geological origin.

    It is questionable whether the Maslach Burnout is suitable for studying burnout prevalence in preclinical medical students because many questions are patient-centered and the students have little or no contact with patients. Among factors associated with burnout in medical students, the gender shows conflicting results. The first aim of this study was to investigate the prevalence of the risk of burnout in medical students in preclinical and clinical years of training, using the Maslach Burnout Inventory-Student Survey, specifically designed and validated to assess the burnout in university students, and secondly, to investigate the association between gender and burnout subscales. A cross-sectional study was carried out in a sample of 270 Spanish medical students-176 (65%) in the third year and 94 (35%) in the sixth year of training-using the Maslach Burnout Inventory-Student Survey questionnaire. Internal consistencies (Cronbach's alpha) for the three subscales on the whole sample were as follows: for exhaustion 0.78, cynicism 0.78, and efficacy 0.71. Moreover, the prevalence of burnout risk was significantly higher in sixth-year students 35 (37.5%) compared with students in third year of training 26 (14.8%) (χ(2) test, p burnout subscales. The Maslach Burnout Inventory-Student Survey overcame difficulties encountered when students have little or no contact with patients. Our findings show that the risk of burnout prevalence doubled from the third year to sixth year of training and that gender was not significantly associated with any of the subscales of burnout.

  3. Re-editing the paradigm of Cytidine (C) to Uridine (U) RNA editing.

    Fossat, Nicolas; Tam, Patrick P L

    2014-01-01

    Cytidine (C) to Uridine (U) RNA editing is a post-trancriptional modification that until recently was known to only affect Apolipoprotein b (Apob) RNA and minimally require 2 components of the C to U editosome, the deaminase APOBEC1 and the RNA-binding protein A1CF. Our latest work has identified a novel RNA-binding protein, RBM47, as a core component of the editosome, which can substitute A1CF for the editing of ApoB mRNA. In addition, new RNA species that are subjected to C to U editing have been identified. Here, we highlight these recent discoveries and discuss how they change our view of the composition of the C to U editing machinery and expand our knowledge of the functional attributes of C to U RNA editing.

  4. Ebola virus RNA editing depends on the primary editing site sequence and an upstream secondary structure.

    Directory of Open Access Journals (Sweden)

    Masfique Mehedi

    Full Text Available Ebolavirus (EBOV, the causative agent of a severe hemorrhagic fever and a biosafety level 4 pathogen, increases its genome coding capacity by producing multiple transcripts encoding for structural and nonstructural glycoproteins from a single gene. This is achieved through RNA editing, during which non-template adenosine residues are incorporated into the EBOV mRNAs at an editing site encoding for 7 adenosine residues. However, the mechanism of EBOV RNA editing is currently not understood. In this study, we report for the first time that minigenomes containing the glycoprotein gene editing site can undergo RNA editing, thereby eliminating the requirement for a biosafety level 4 laboratory to study EBOV RNA editing. Using a newly developed dual-reporter minigenome, we have characterized the mechanism of EBOV RNA editing, and have identified cis-acting sequences that are required for editing, located between 9 nt upstream and 9 nt downstream of the editing site. Moreover, we show that a secondary structure in the upstream cis-acting sequence plays an important role in RNA editing. EBOV RNA editing is glycoprotein gene-specific, as a stretch encoding for 7 adenosine residues located in the viral polymerase gene did not serve as an editing site, most likely due to an absence of the necessary cis-acting sequences. Finally, the EBOV protein VP30 was identified as a trans-acting factor for RNA editing, constituting a novel function for this protein. Overall, our results provide novel insights into the RNA editing mechanism of EBOV, further understanding of which might result in novel intervention strategies against this viral pathogen.

    Multilingualism is common offline, but we have a more limited understanding of the ways multilingualism is displayed online and the roles that multilinguals play in the spread of content between speakers of different languages. We take a computational approach to studying multilingualism using one of the largest user-generated content platforms, Wikipedia. We study multilingualism by collecting and analyzing a large dataset of the content written by multilingual editors of the English, German, and Spanish editions of Wikipedia. This dataset contains over two million paragraphs edited by over 15,000 multilingual users from July 8 to August 9, 2013. We analyze these multilingual editors in terms of their engagement, interests, and language proficiency in their primary and non-primary (secondary) languages and find that the English edition of Wikipedia displays different dynamics from the Spanish and German editions. Users primarily editing the Spanish and German editions make more complex edits than users who edit these editions as a second language. In contrast, users editing the English edition as a second language make edits that are just as complex as the edits by users who primarily edit the English edition. In this way, English serves a special role bringing together content written by multilinguals from many language editions. Nonetheless, language remains a formidable hurdle to the spread of content: we find evidence for a complexity barrier whereby editors are less likely to edit complex content in a second language. In addition, we find that multilinguals are less engaged and show lower levels of language proficiency in their second languages. We also examine the topical interests of multilingual editors and find that there is no significant difference between primary and non-primary editors in each language.

    Angelin, Martin; Evengård, Birgitta; Palmgren, Helena

    2015-07-01

    The numbers of university students studying abroad increase every year. These students are not tourists as their studies require different types of travel that expose them to different risks. Moreover, health care students (HCSs) may be exposed to even greater risks according to their travel destinations and itineraries. Clearly, research-based pre-travel advice is needed. This study reports on a prospective survey conducted from April 2010 to January 2014 of health care and non-health care students from Swedish universities in Umeå, Stockholm and Gothenburg studying abroad. Of the 393 students included in the study, 85% responded. Over half (55%) were HCSs. Pre-travel health information was received by 79% and information on personal safety by 49% of HCSs. The rate of illness during travel was 52%. Health care students more often travelled to developing regions and were at increased risk for travellers' diarrhoea. One in 10 experienced theft and 3% were involved in traffic accidents. One in five met a new sexual partner during travel and 65% of these practised safe sex. Half of all participants increased their alcohol consumption while abroad; high alcohol consumption was associated with increased risk for being a victim of theft, as well as for meeting a new sexual partner during travel. University authorities are responsible for the safety and well-being of students studying abroad. This study supplies organisers and students with epidemiological data that will help improve pre-travel preparation and increase student awareness of the potential risks associated with studying abroad. © 2015 John Wiley & Sons Ltd.

    Full Text Available Background: Life style related behavioural risk factors are mainly implicated for increased burden of cardio- vascular diseases. Research related to these risk behaviours especially among medical students is essential, considering their role as future physicians and role models in public health intervention programmes. Objective: To evaluate the burden of cardiovascular risk behaviours among students of a medical college of Delhi, India. Materials and Methods: A cross sectional study was carried out among undergraduate medical students of a medical college in Delhi. Self administered questionnaire was used to collect information on identification data and risk behaviours in relation to cardiovascular diseases. Binary logistic regression analysis was done to calculate adjusted odds ratio to assess association between risk behaviours and covariates. Results: The minimum recommendation of taking at least five servings per day of fruits and vegetables was complied only by 12% of students. Consumption of carbonated soft drinks either once or more on daily basis was present in 23.7% students and 32.0% reported frequent consumption of fast foods in past week. Consumption of alcohol was present in 28.8% students but only small proportion of students (7% was current tobacco users. Large proportions of students (42.6% were either not carrying out or were involved in only occasional physical activity in past week. Conclusions: Unhealthy behavioural practises are present and may progress as student advance through medical college. Developing strategies targeting at these risk behaviours and determining factors is necessary to promote healthy life style among medical students.

    The RNA Editing Database (REDIdb) is an interactive, web-based database created and designed with the aim to allocate RNA editing events such as substitutions, insertions and deletions occurring in a wide range of organisms. The database contains both fully and partially sequenced DNA molecules for which editing information is available either by experimental inspection (in vitro) or by computational detection (in silico). Each record of REDIdb is organized in a specific flat-file containing a description of the main characteristics of the entry, a feature table with the editing events and related details and a sequence zone with both the genomic sequence and the corresponding edited transcript. REDIdb is a relational database in which the browsing and identification of editing sites has been simplified by means of two facilities to either graphically display genomic or cDNA sequences or to show the corresponding alignment. In both cases, all editing sites are highlighted in colour and their relative positions are detailed by mousing over. New editing positions can be directly submitted to REDIdb after a user-specific registration to obtain authorized secure access. This first version of REDIdb database stores 9964 editing events and can be freely queried at http://biologia.unical.it/py_script/search.html.

  18. Dana's Minerals and How to Study Them, Fourth Edition

    Science.gov (United States)

    Cribb, Warner

    Anyone who spends time in a geology lab, natural science museum, or rock and mineral shop can see that nature provides us with an incredible variety of minerals. Countless introductory geology students get “turned on” to the science of geology by studying minerals. Despite the development of modern instruments that enable rapid and detailed mineral, chemical, and atomic structural analysis, the study of minerals by hand sample remains one of the most popular and economical pursuits of many professional geologists, students, and amateur mineral enthusiasts.Because individuals with varying backgrounds in physical science collect and study minerals, a considerable need exists for a reference text that can be effectively used by both professionals and amateurs. Edward Salisbury Dana published the first such text, Minerals and How to Study Them, over a century ago. The third and last edition of this book was published in 1948. In the 50 years since, considerable changes have occurred in the understanding of mineral chemistry, crystallography, and microscopy. As a result, Dana's third edition is somewhat out of date, and its presentation of material is somewhat antiquated for modern-day readers.

    Along with the progressive acceleration of urbanization, the need to identify potentially troublesome "Not In My Back Yard" (NIMBY) facilities in the city is inevitable. To resolve NIMBY conflict, it is important to know people's NIMBY risk acceptability for these facilities. A questionnaire survey was used among Chinese and Japanese college students to identify NIMBY risk acceptability. LISREL was used to construct a structural equation model to analyze the difference in NIMBY risk acceptability between the Chinese and Japanese college students. Factors that may affect NIMBY risk acceptability were analyzed: "perceiving utility," "perceiving risk," "trust in government," "reasonable compensation," and "procedural justice." The findings show that Japanese students' concerns were greater than Chinese students' concerns. Perceiving utility and perceiving risk were the most important factors that affect people's NIMBY risk acceptability, followed by procedural justice, trust in government, and reasonable compensation. There is a difference between the different cultural backgrounds in confronting the risk: Chinese students focus more on the reputation and value of real estate, while Japanese students pay more attention to environmental pollution and damage to health. Furthermore, cultural influences play a role in students' risk perception. To improve the risk acceptability for NIMBY facilities and provide a basis for resolving NIMBY conflicts, it is necessary to ensure the benefits of the NIMBY facility while reducing environmental pollution. The findings of this study may be of interest for policy makers and practitioners to devise future NIMBY strategies.

    It is well recognized that professional musicians are at risk of hearing damage due to the exposure to high sound pressure levels during music playing. However, it is important to recognize that the musicians' exposure may start early in the course of their training as students in the classroom and at home. Studies regarding sound exposure of music students and their hearing disorders are scarce and do not take into account important influencing variables. Therefore, this study aimed to describe sound level exposures of music students at different music styles, classes, and according to the instrument played. Further, this investigation attempted to analyze the perceptions of students in relation to exposure to loud music and consequent health risks, as well as to characterize preventive behaviors. The results showed that music students are exposed to high sound levels in the course of their academic activity. This exposure is potentiated by practice outside the school and other external activities. Differences were found between music style, instruments, and classes. Tinnitus, hyperacusis, diplacusis, and sound distortion were reported by the students. However, students were not entirely aware of the health risks related to exposure to high sound pressure levels. These findings reflect the importance of starting intervention in relation to noise risk reduction at an early stage, when musicians are commencing their activity as students.

  5. Structure of the Wechsler Intelligence Scale for Children--Fourth Edition among a national sample of referred students.

    Watkins, Marley W

    2010-12-01

    The structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; D. Wechsler, 2003a) was analyzed via confirmatory factor analysis among a national sample of 355 students referred for psychoeducational evaluation by 93 school psychologists from 35 states. The structure of the WISC-IV core battery was best represented by four first-order factors as per D. Wechsler (2003b), plus a general intelligence factor in a direct hierarchical model. The general factor was the predominate source of variation among WISC-IV subtests, accounting for 48% of the total variance and 75% of the common variance. The largest 1st-order factor, Processing Speed, only accounted for 6.1% total and 9.5% common variance. Given these explanatory contributions, recommendations favoring interpretation of the 1st-order factor scores over the general intelligence score appear to be misguided.

  8. Novel Features and Considerations for ERA and Regulation of Crops Produced by Genome Editing

    Directory of Open Access Journals (Sweden)

    Nina Duensing

    2018-06-01

    Full Text Available Genome editing describes a variety of molecular biology applications enabling targeted and precise alterations of the genomes of plants, animals and microorganisms. These rapidly developing techniques are likely to revolutionize the breeding of new crop varieties. Since genome editing can lead to the development of plants that could also have come into existence naturally or by conventional breeding techniques, there are strong arguments that these cases should not be classified as genetically modified organisms (GMOs and be regulated no differently from conventionally bred crops. If a specific regulation would be regarded necessary, the application of genome editing for crop development may challenge risk assessment and post-market monitoring. In the session “Plant genome editing—any novel features to consider for ERA and regulation?” held at the 14th ISBGMO, scientists from various disciplines as well as regulators, risk assessors and potential users of the new technologies were brought together for a knowledge-based discussion to identify knowledge gaps and analyze scenarios for the introduction of genome-edited crops into the environment. It was aimed to enable an open exchange forum on the regulatory approaches, ethical aspects and decision-making considerations.

    The Clouds and Earth's Radiant Energy System (CERES) analyzes MODerate-resolution Imaging Spectroradiometer (MODIS) data and Visible Infrared Imaging Radiometer Suite (VIIRS) to derive cloud properties that are combine with aerosol and CERES broadband flux data to create a multi-parameter data set for climate study. CERES has produced over 15 years of data from Terra and over 13 years of data from Aqua using the CERES-MODIS Edition-2 cloud retrieval algorithm. A recently revised algorithm, CERESMODIS Edition 4, has been developed and is now generating enhanced cloud data for climate research (over 10 years for Terra and 8 years for Aqua). New multispectral retrievals of properties are included along with a multilayer cloud retrieval system. Cloud microphysical properties are reported at 3 wavelengths, 0.65, 1.24, and 2.1 microns to enable better estimates of the vertical profiles of cloud water contents. Cloud properties over snow are retrieved using the 1.24-micron channel. A new CERES-VIIRS cloud retrieval package was developed for the VIIRS spectral complement and is currently producing the CERES-VIIRS Edition 1 cloud dataset. The results from CERES-MODIS Edition 4 and CERES-VIIRS Edition 1 are presented and compared with each other and other datasets, including CALIPSO, CloudSat and the CERES-MODIS Edition-2 results.

    To study the prevalence of symptoms of eating disorders and risk eating behaviours and the relationship between life at a dance school and the risk of developing an eating disorder (ED) in an adolescent population of Spanish dance students. Questionnaires were used to assess attitudes to eating, cultural influences on the body shape model, eating disorders (DSM-IV) and risk factors for eating disorders in 76 adolescent dance students (age 12-17 years) at the Barcelona Theatre Institute. Subjects were compared with a community sample of 453 female adolescents. To study the relationship between ED and characteristics of this particular school, an original questionnaire was administered to 105 students at the school aged from 12 to 21 years. The prevalence of eating disorders and several risk attitudes and behaviours were similar in the dance students and the female adolescents from the general population. Students at risk of eating disorders perceived greater pressure from coaches concerning eating, appearance, weight and artistic performance; they felt less satisfied with their weight and weighed themselves more often; they avoided performing so as not to exhibit their body in public, disliked comparing their body with their peers and believed that audiences paid a great deal of attention to their bodies. In contrast, Body Mass Index (BMI) had hardly any influence on these experiences. Depressive symptoms were associated almost exclusively with experience of stressors and aversive situations. Dance school students do not necessarily present a greater risk of ED than other girls of the same age. The risk of ED may be associated with greater pressure from coaches, with attitudes related to the ED itself, or with depressive symptoms, rather than with the BMI.

    To determine which admissions variables and curricular outcomes are predictive of being at risk of failing the Medical Council of Canada Qualifying Examination Part 1 (MCCQE1), how quickly student risk of failure can be predicted, and to what extent predictive modeling is possible and accurate in estimating future student risk. Data from five graduating cohorts (2011-2015), Schulich School of Medicine & Dentistry, Western University, were collected and analyzed using hierarchical generalized linear models (HGLMs). Area under the receiver operating characteristic curve (AUC) was used to evaluate the accuracy of predictive models and determine whether they could be used to predict future risk, using the 2016 graduating cohort. Four predictive models were developed to predict student risk of failure at admissions, year 1, year 2, and pre-MCCQE1. The HGLM analyses identified gender, MCAT verbal reasoning score, two preclerkship course mean grades, and the year 4 summative objective structured clinical examination score as significant predictors of student risk. The predictive accuracy of the models varied. The pre-MCCQE1 model was the most accurate at predicting a student's risk of failing (AUC 0.66-0.93), while the admissions model was not predictive (AUC 0.25-0.47). Key variables predictive of students at risk were found. The predictive models developed suggest, while it is not possible to identify student risk at admission, we can begin to identify and monitor students within the first year. Using such models, programs may be able to identify and monitor students at risk quantitatively and develop tailored intervention strategies.

    International nursing electives have been identified as a positive learning experience for students. However, whilst there are risks associated with international student placements in general, there is a scarcity of research specifically relating to student nurse's experiences of risk. This study aimed to investigate UK undergraduate student nurse experiences of risk during an international placement. A phenomenological methodology was applied and semi-structured interviews were conducted with student nurses who had recently returned from an international clinical placement abroad. Ten, second year student nurses, studying on a pre-registration diploma/BSc (Hons) Nursing Studies/Registered Nurse programme from one UK University participated in the study. Findings from the study highlighted that students felt that three types of risk existed; physical risk, clinical-professional risk and socio-cultural risk. Perceptions of risk were influenced by sociological theory relating to the concept of 'the other' and students attempted to reduce risk by employing strategies to reduce 'Otherness'. They also applied psychological theory relating to heuristics such as 'safety in numbers.' It also emerged from the study that exposure to perceived risk enhanced learning as students reported that it encouraged personal and professional development in particular and so assisted students in their move toward self-actualisation. It is suggested, and intended, that findings from this study can be applied to the preparation of students to further enhance their safety and learning experience during international placements abroad.

    Many schools engage in health promotion, health interventions, and services aimed at improving the health and well-being outcomes for students. The purpose of this study was to examine the effects of schools on student health risk-taking behaviors and depressive symptoms. A nationally representative sample (n = 9,056) of students from 96 secondary schools completed a health and well-being survey using Internet Tablets that included questions on school climate, health risk-taking behaviors, and mental health. Teachers (n = 2,901) and school administrators (n = 91) completed questionnaires on aspects of the school climate which included teacher well-being and burnout, the staff work environment, health and welfare services for students, and school organizational support for student health and well-being. Multilevel models were used to estimate school effects on the health risk-taking behaviors and depression symptoms among students. Schools where students reported a more positive school climate had fewer students with alcohol use problems, and fewer students engaging in violence and risky motor vehicle behaviors. Schools where teachers reported better health and welfare services for students had fewer students engaging in unsafe sexual health behaviors. Schools where teachers reported higher levels of well-being had fewer students reporting significant levels of depressive symptoms. More positive school climates and better school health and welfare services are associated with fewer health risk-taking behaviors among students. However, the overall school effects were modest, especially for cigarette use and suicidal behaviors. Copyright © 2011 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Now more than ever, organizations must plan, response and recognize all forms of risks that they face. "Fundamentals of Risk Management", now in its second edition, provides a comprehensive introduction to the subject of commercial and business risk for anyone studying for a career in risk as well as a broad range of risk professionals. It examines the key components of risk management and its application with examples to demonstrate its benefit to organisations in the public and private sector. The second edition has been completely updated to take into account the greater influence of ISO 3100, the emergence of Governance Risk and Compliance (GRC) and the wide use of the bowtie method to illustrate risk management. In addition, there is now a chapter on the skills and competencies required by an effective risk manager.

  2. Using data to help increase STEM retention rates for at-risk students; Student expectations and skill building

    Reed, D. E.; Jones, G.; Heaney, A.

    2013-12-01

    Retention in the STEM fields is often a focus for higher education due to a shortage of trained workforce members. In particular, much effort has been spent on first year retention rates and introductory level courses under the assumption that students are more likely to drop out of STEM majors early in their higher education degree progress. While the retention rates of women, minorities, and low income students have been a priority by both the National Science Foundation and the private sector, we are interested in at-risk first year students for this study. The University of Wyoming Synergy Program's goal is to promote academic success and retention for underprepared and at-risk students by creating a series of first semester curricula as theme-based college transition skills courses that are paired with English courses. This creates a cohort group of courses for the students with increased communication between instructors at the same time allowing greater development of student social networks. In this study we are highlighting the results of the STEM students as compared with other at-risk participants in the program. The Synergy Program enrolls approximately 144 students each year with pre- and post-course surveys that directly measure which college skills students select as important as well as student expectations of the amount of time required for STEM courses. Follow-up surveys track the same queries for students who persist to their junior and senior year. In addition, instructors complete a summative survey about skills they find important to student success and individual student's challenges and successes with a variety of skills. Our results show a large gap in skills between those identified as important by students and those identified by their instructors. Expectations for the amount of time required to complete work for STEM courses and the reported time spent on course work are not constant when progressing throughout college. This analysis

    This paper is a report of a study conducted to test the validity and reliability of the Reynolds Adolescent Depression Scale - Second Edition in Korean culture. Depression is a significant mental health problem in adolescents. The Reynolds Adolescent Depression Scale - Second Edition has been shown to be a useful tool to assess depression in adolescents, with extensive research on this measure having been conducted in western cultures. Measures developed in western cultures need to be tested and validated before being used in Asian cultures. The participants were a convenience sample of 440 Korean adolescents with a mean age of 13.78 years (sd = 0.95) from grades 7 to 9 in three public middle schools in South Korea. A cross-sectional design was used. Back-translation was used to create the Korean version, with additional testing for cultural meaning and comprehension. The data were collected at the end of 2004. Internal consistency reliability for the Korean version of the Reynolds Adolescent Depression Scale - Second Edition was 0.89, with subscale reliability ranging from 0.66 to 0.81. Evidence for criterion-related, convergent and discriminant validity for the Korean version of the Reynolds Adolescent Depression Scale - Second Edition was found. Confirmatory factor analysis supported the 4-factor structure of Reynolds Adolescent Depression Scale - Second Edition. Our results support the validity and reliability for the Korean version of the Reynolds Adolescent Depression Scale - Second Edition as a measure of depression and suggest that it can be used to screen students and to evaluate the effectiveness of preventive interventions in school settings.

  4. Small RNA and A-to-I Editing in Autism Spectrum Disorders

    Science.gov (United States)

    Eran, Alal

    One in every 88 children is diagnosed with Autism Spectrum Disorders (ASDs), a set of neurodevelopmental conditions characterized by social impairments, communication deficits, and repetitive behavior. ASDs have a substantial genetic component, but the specific cause of most cases remains unknown. Understanding gene-environment interactions underlying ASD is essential for improving early diagnosis and identifying critical targets for intervention and prevention. Towards this goal, we surveyed adenosine-to-inosine (A-to-I) RNA editing in autistic brains. A-to-I editing is an epigenetic mechanism that fine-tunes synaptic function in response to environmental stimuli, shown to modulate complex behavior in animals. We used ultradeep sequencing to quantify A-to-I receding of candidate synaptic genes in postmortem cerebella from individuals with ASD and neurotypical controls. We found unexpectedly wide distributions of human A-to-I editing levels, whose extremes were consistently populated by individuals with ASD. We correlated A-to-I editing with isoform usage, identified clusters of correlated sites, and examined differential editing patterns. Importantly, we found that individuals with ASD commonly use a dysfunctional form of the editing enzyme ADARB1. We next profiled small RNAs thought to regulate A-to-I editing, which originate from one of the most commonly altered loci in ASD, 15q11. Deep targeted sequencing of SNORD115 and SNORD116 transcripts enabled their high-resolution detection in human brains, and revealed a strong gender bias underlying their expression. The consistent 2-fold upregulation of 15q11 small RNAs in male vs. female cerebella could be important in delineating the role of this locus in ASD, a male dominant disorder. Overall, these studies provide an accurate population-level view of small RNA and A-to-I editing in human cerebella, and suggest that A-to-I editing of synaptic genes may be informative for assessing the epigenetic risk for autism

    We propose a connectivity editing framework for quad-dominant meshes. In our framework, the user can edit the mesh connectivity to control the location, type, and number of irregular vertices (with more or fewer than four neighbors) and irregular faces (non-quads). We provide a theoretical analysis of the problem, discuss what edits are possible and impossible, and describe how to implement an editing framework that realizes all possible editing operations. In the results, we show example edits and illustrate the advantages and disadvantages of different strategies for quad-dominant mesh design. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and John Wiley & Sons Ltd.

    The most important factor which predisposes young people to suicide is depression, although protective factors such as self-esteem, emotional adaptation and social support may reduce the probability of suicidal ideation and suicide attempts. Several studies have indicated an elevated risk of suicide for health-related professions. Little is known, however, about the relationship between perceived emotional intelligence and suicide risk among nursing students. The main goals were to determine the prevalence of suicide risk in a sample of nursing students, to examine the relationship between suicide risk and perceived emotional intelligence, depression, trait anxiety and self-esteem, and to identify any gender differences in relation to these variables. Cross-sectional study of nursing students (n=93) who completed self-report measures of perceived emotional intelligence (Trait Meta-Mood Scale, which evaluates three dimensions: emotional attention, clarity and repair), suicide risk (Plutchik Suicide Risk Scale), self-esteem (Rosenberg Self-esteem Scale), depression (Zung Self-Rating Depression Scale) and anxiety (Trait scale of the State-Trait Anxiety Inventory). Linear regression analysis confirmed that depression and emotional attention are significant predictors of suicidal ideation. Moreover, suicide risk showed a significant negative association with self-esteem and with emotional clarity and repair. Gender differences were only observed in relation to depression, on which women scored significantly higher. Overall, 14% of the students were considered to present a substantial suicide risk. The findings suggest that interventions to prevent suicidal ideation among nursing students should include strategies to detect mood disorders (especially depression) and to improve emotional coping skills. In line with previous research the results indicate that high scores on emotional attention are linked to heightened emotional susceptibility and an increased risk of

    2012-02-01

    The central dogma of molecular Biology states that DNA is transcribed base by base into RNA which is in turn translated into proteins. However, some organisms edit their RNA before translation by inserting, deleting, or substituting individual or short stretches of bases. In many instances the mechanisms by which an organism recognizes the positions at which to edit or by which it performs the actual editing are unknown. One model system that stands out by its very high rate of on average one out of 25 bases being edited are the Myxomycetes, a class of slime molds. In this talk we will show how the computational methods and concepts from statistical Physics can be used to analyze DNA and protein sequence data to predict editing sites in these slime molds and to guide experiments that identified previously unknown types of editing as well as the complete set of editing events in the slime mold Physarum polycephalum.

    2016-12-09

    Nationally, approximately one third of older adults fall each year. Falls and resulting injury result in decreased mobility, functional impairment, loss of independence, and increased mortality. Utilization of evidence-based protocols by health care providers to identify older adults at risk of falling is limited, and rates of participation by older adults in prevention activities is low. Because of nursing's increasing role in caring for older adults, development of fall prevention education for nursing students would result in increased awareness of the need for fall prevention in community-dwelling older adults and increased access of older adults to falls risk assessment. There is a need to extend research to inform teaching and learning strategies for fall prevention. After pretesting, a convenience sample of 52 undergraduate nursing students and 22 graduate nursing students completed an online education program and performed a falls risk assessment on an older adult. After completing the clinical assignment, students completed a posttest and self-efficacy survey. Data were analyzed using multivariate statistical tests. Results revealed an increase in knowledge and student self-reporting of efficacy of fall risk assessment skills for the older adult population. This study suggests that nursing students acquired the necessary knowledge and self-efficacy for assessing fall risk of older adults through the combination of an online learning module and participating in actual fall risk assessment of an older adult.

    With CRISPR/Cas9 and other genome-editing technologies, successful somatic and germline genome editing are becoming feasible. To respond, an American Society of Human Genetics (ASHG) workgroup developed this position statement, which was approved by the ASHG Board in March 2017. The workgroup included representatives from the UK Association of Genetic Nurses and Counsellors, Canadian Association of Genetic Counsellors, International Genetic Epidemiology Society, and US National Society of Genetic Counselors. These groups, as well as the American Society for Reproductive Medicine, Asia Pacific Society of Human Genetics, British Society for Genetic Medicine, Human Genetics Society of Australasia, Professional Society of Genetic Counselors in Asia, and Southern African Society for Human Genetics, endorsed the final statement. The statement includes the following positions. (1) At this time, given the nature and number of unanswered scientific, ethical, and policy questions, it is inappropriate to perform germline gene editing that culminates in human pregnancy. (2) Currently, there is no reason to prohibit in vitro germline genome editing on human embryos and gametes, with appropriate oversight and consent from donors, to facilitate research on the possible future clinical applications of gene editing. There should be no prohibition on making public funds available to support this research. (3) Future clinical application of human germline genome editing should not proceed unless, at a minimum, there is (a) a compelling medical rationale, (b) an evidence base that supports its clinical use, (c) an ethical justification, and (d) a transparent public process to solicit and incorporate stakeholder input.

    Although there is substantial evidence that health risk behaviors increase risks of premature morbidity and mortality, little is known about the multiple health risk behaviors in Chinese college students. Here, we investigated the prevalence of multiple health risk behaviors and its relation to mental health among Chinese college students. A cross-sectional study was conducted in Wuhan, China from May to June 2012. The students reported their health risk behaviors using self-administered questionnaires. Depression and anxiety were assessed using the self-rating depression scale and self-rating anxiety scale, respectively. A total of 2422 college students (1433 males) aged 19.7 ± 1.2 years were participated in the study. The prevalence of physical inactivity, sleep disturbance, poor dietary behavior, Internet addiction disorder (IAD), frequent alcohol use and current smoking was 62.0, 42.6, 29.8, 22.3, 11.6 and 9.3%, respectively. Significantly increased risks for depression and anxiety were found among students with frequent alcohol use, sleep disturbance, poor dietary behavior and IAD. Two-step cluster analysis identified two different clusters. Participants in the cluster with more unhealthy behaviors showed significantly increased risk for depression (odds ratio (OR): 2.21; 95% confidence interval (CI): 1.83, 2.67) and anxiety (OR: 2.32; 95% CI: 1.85, 2.92). This study indicates that a relatively high prevalence of multiple health risk behaviors was found among Chinese college students. Furthermore, the clustering of health risk behaviors was significantly associated with increased risks for depression and anxiety.

    2011-12-12

    We propose new connectivity editing operations for quadrilateral meshes with the unique ability to explicitly control the location, orientation, type, and number of the irregular vertices (valence not equal to four) in the mesh while preserving sharp edges. We provide theoretical analysis on what editing operations are possible and impossible and introduce three fundamental operations to move and re-orient a pair of irregular vertices. We argue that our editing operations are fundamental, because they only change the quad mesh in the smallest possible region and involve the fewest irregular vertices (i.e., two). The irregular vertex movement operations are supplemented by operations for the splitting, merging, canceling, and aligning of irregular vertices. We explain how the proposed highlevel operations are realized through graph-level editing operations such as quad collapses, edge flips, and edge splits. The utility of these mesh editing operations are demonstrated by improving the connectivity of quad meshes generated from state-of-art quadrangulation techniques. © 2011 ACM.

    Genome editing is defined as highly-effective and precise modification of cellular genome in a large scale. In recent years, such genome-editing methods have been rapidly developed in the field of industrial strain improvement. The quickly-updating methods thoroughly change the old mode of inefficient genetic modification, which is "one modification, one selection marker, and one target site". Highly-effective modification mode in genome editing have been developed including simultaneous modification of multiplex genes, highly-effective insertion, replacement, and deletion of target genes in the genome scale, cut-paste of a large DNA fragment. These new tools for microbial genome editing will certainly be applied widely, and increase the efficiency of industrial strain improvement, and promote the revolution of traditional fermentation industry and rapid development of novel industrial biotechnology like production of biofuel and biomaterial. The technological principle of these genome-editing methods and their applications were summarized in this review, which can benefit engineering and construction of industrial microorganism.

    2015-06-01

    Full Text Available Background: Cardiovascular diseases (CVDs are global epidemic and contribute to double burden in developing countries. Individual’s dietary habits and risk behavior influence the onset and progression of CVDs. Medical students are future role models of the society and their knowledge, habits and behavior can influence their practice in prevention of CVDs in general population. Aims & Objectives: To assess the prevalence of common cardiovascular risk factors among a sample of medical students. Methods: A cross-sectional survey was conducted among the medical students of the four professional years.  An anonymous self-administered questionnaire was used to assess the prevalent cardiovascular risk factors, dietary habits and risk behavior among the medical students. Results: Family history of CVD, obesity and hypertension were highly prevalent among the medical students. Majority of them took <5 servings of fruit or vegetables per day (97.6%, ate junk foods (91.3% and had long sedentary activity (47.6%. Taking red meat intake (OR 4.79, junk foods (Odds Ratio, OR 2.59, and snacking habit (OR 1.73 was observed more among male students; no physical activity or sports was significantly more in females. Logistic regression analysis showed that a family history of CVD was strongly associated with hypertension and obesity among medical students while exercise was protective against hypertension. Conclusion: The medical students had very poor compliance to recommended dietary intake and physical activity. Generating awareness, incorporating healthy habits and introducing structured educational programs into medical curriculum will help in changing lifestyle.

    the genome. Due to its precision, gene editing is more precise than either conventional crop breeding methods or standard genetic engineering methods. Thus this technology is a very powerful tool that can be used toward securing the world's food supply. In addition to improving the nutritional value of crops, it is the most effective way to produce crops that can resist pests and thrive in tough climates. There are 3 types of modifications produced by genome editing; Type I includes altering a few nucleotides, Type II involves replacing an allele with a pre-existing one and Type III allows for the insertion of new gene(s) in predetermined regions in the genome. Because most genome-editing techniques can leave behind traces of DNA alterations evident in a small number of nucleotides, crops created through gene editing could avoid the stringent regulation procedures commonly associated with GM crop development. For this reason many scientists believe plants improved with the more precise gene editing techniques will be more acceptable to the public than transgenic plants. With genome editing comes the promise of new crops being developed more rapidly with a very low risk of off-target effects. It can be performed in any laboratory with any crop, even those that have complex genomes and are not easily bred using conventional methods.

    Early assessment and management of risk factors is known to have significant impact in preventing cardiovascular disease (CVD) and its associated burden. Cardiovascular disease risk assessment and management (CVDRAM) is best approached by teamwork across health care professionals. This study aimed at assessing health care students' (HCSs) knowledge about the parameters needed for estimating CVD risk, their self-assessed preparedness/confidence and perceived barriers for the provision of CVDRAM services through a survey administered to third and fourth year pharmacy, medical, and nursing students in Qatar. Although all student cohorts achieved similar knowledge scores, less than half ( n = 38, 47%) were able to identify all of the six main risk factors necessary to estimate absolute CVD risk, and a third (32%) were unable to identify total cholesterol as an independent risk factor necessary to estimate CVD risk. Training on the use of CVD risk assessment tools differed among the three student cohorts. All student cohorts also perceived similar levels of preparedness in CVDRAM. However, pharmacy students reported the highest preparedness/confidence with the use of the latest CVDRAM guidelines. The majority of statements listed under the barriers scale were perceived by the students as being moderate (median score = 3). Poor public acceptance or unawareness of importance of estimating CVD risk was the only barrier perceived as a major by nursing students. Future integration of interprofessional educational (IPE) activities in the CVDRAM curricula of HCSs may be a suitable strategy to minimize barriers and foster collaborative practice for the provision of CVDRAM services in Qatar.

  18. Deletions in cox2 mRNA result in loss of splicing and RNA editing and gain of novel RNA editing sites.

    Directory of Open Access Journals (Sweden)

    Stefanie Grüttner

    Full Text Available As previously demonstrated, the maize cox2 RNA is fully edited in cauliflower mitochondria. Use of constructs with a deleted cox2 intron, however, led to a loss of RNA editing at almost all editing sites, with only a few sites still partially edited. Likewise, one deletion in exon 1 and three in exon 2 abolish RNA editing at all cox2 sites analyzed. Furthermore, intron splicing is abolished using these deletions. Mutation of a cytosine residue, which is normally edited and localized directly adjacent to the intron, to thymidine did not result in restoration of splicing, indicating that the loss of splicing was not due to loss of RNA editing. One deletion in exon 2 did not lead to loss of splicing. Instead, most editing sites were found to be edited, only three were not edited. Unexpectedly, we observed additional RNA editing events at new sites. Thus it appears that deletions in the cox2 RNA sequence can have a strong effect on RNA processing, leading to loss of splicing, loss of editing at all sites, or even to a gain of new editing sites. As these effects are not limited to the vicinity of the respective deletions, but appear to be widespread or even affect all editing sites, they may not be explained by the loss of PPR binding sites. Instead, it appears that several parts of the cox2 transcript are required for proper RNA processing. This indicates the roles of the RNA sequence and structural elements in the recognition of the editing sites.

    For the majority of Polish students school is a source of negative experiences and therefore may increase the risk of adolescent problem behaviors. The results of the study conducted in Warsaw middle schools (N=2244, 54% girls) indicated that changes for worse (between 7 and 8 grade) in students' behavior increase the risk of drug use. However, changes for better in students' perception of school value and school achievements are risk factors, too (even when family and peer risk factors are controlled). PMID:21152104

    Full Text Available RNA editing is vital to provide the RNA and protein complexity to regulate the gene expression. Correct RNA editing maintains the cell function and organism development. Imbalance of the RNA editing machinery may lead to diseases and cancers. Recently, RNA editing has been recognized as a target for drug discovery although few studies targeting RNA editing for disease and cancer therapy were reported in the field of natural products. Therefore, RNA editing may be a potential target for therapeutic natural products. In this review, we provide a literature overview of the biological functions of RNA editing on gene expression, diseases, cancers, and drugs. The bioinformatics resources of RNA editing were also summarized.

    This is a descriptive study examining nursing students' perceptions of the environmental risks and their environmental attitudes. The study population comprised 2364 nursing students studying at universities in Istanbul in the fall semester of the 2012-2013 academic year. The sampling group was formed by 778 students which were selected by a stratified random sampling procedure. The data were collected using "The Student Personal Information Form", "The Environmental Risk Perception Scale" and "The Environmental Attitudes Scale". The students' mean score on perceptions of environmental risk was 6.04 ± 0.81(min 2.56; max 7.00) and the mean score of their environmental attitudes was 4.02 ± 0.47(min 2.28; max 5.00). It was determined that factors such as gender, interest in environmental issues, endorsement of the college course on environment as necessary, and participation in an environmental activity and awareness of non-government environmental organizations affected the environmental risk perception and environmental attitudes. A moderate positive relationship (r = 0.366, p environmental risk perceptions and their environmental attitudes.

    Environmental destruction is one of the most important problems in this century. The aim of the study was to determine the environmental attitudes and perceived risks associated with environmental factors of the students. This cross-sectional study was conducted in 7 faculties of Mersin University. The research data were collected using a questionnaire. The questionnaire included sociodemographic characteristics, the "Environmental Attitudes Scale," and the "Environmental Risk Perception Scale." 774 students who filled out questionnaires were evaluated. The sample included 55.8% females. Environmental Attitudes Scale mean scores of students were identified as 81.1 ± 11.3. The highest perceived risk was release of radioactive materials associated with nuclear power generation. The environmental attitudes and risk perception scores were higher in Health Sciences than in the other faculties. Females were more positive towards the environment and had higher risk perceptions than the men. There is a negative correlation between age and resource depletion risk and global environmental risk score. Students had a positive attitude to the environment and had moderate-level risk perception about the environment. Environmental awareness of students, especially those studying in the Social Sciences, should be increased. The environmental education curriculum should be revised throughout all the courses.

  5. ADAR2 editing activity in newly diagnosed versus relapsed pediatric high-grade astrocytomas

    High-grade (WHO grade III and IV) astrocytomas are aggressive malignant brain tumors affecting humans with a high risk of recurrence in both children and adults. To date, limited information is available on the genetic and molecular alterations important in the onset and progression of pediatric high-grade astrocytomas and, even less, on the prognostic factors that influence long-term outcome in children with recurrence. A-to-I RNA editing is an essential post-transcriptional mechanism that can alter the nucleotide sequence of several RNAs and is mediated by the ADAR enzymes. ADAR2 editing activity is particularly important in mammalian brain and is impaired in both adult and pediatric high-grade astrocytomas. Moreover, we have recently shown that the recovered ADAR2 activity in high-grade astrocytomas inhibits in vivo tumor growth. The aim of the present study is to investigate whether changes may occur in ADAR2-mediated RNA editing profiles of relapsed high-grade astrocytomas compared to their respective specimens collected at diagnosis, in four pediatric patients. Total RNAs extracted from all tumor samples and controls were tested for RNA editing levels (by direct sequencing on cDNA pools) and for ADAR2 mRNA expression (by qRT-PCR). A significant loss of ADAR2-editing activity was observed in the newly diagnosed and recurrent astrocytomas in comparison to normal brain. Surprisingly, we found a substantial rescue of ADAR2 editing activity in the relapsed tumor of the only patient showing prolonged survival. High-grade astrocytomas display a generalized loss of ADAR2-mediated RNA editing at both diagnosis and relapse. However, a peculiar Case, in complete remission of disease, displayed a total rescue of RNA editing at relapse, intriguingly suggesting ADAR2 activity/expression as a possible marker for long-term survival of patients with high-grade astrocytomas

    Senior medical students represent future physicians who commonly refer patients for diagnostic imaging studies that may involve ionizing radiation. The radiology curriculum at the University of British Columbia provides students with broad-based knowledge about common imaging examinations. The purpose of this study was to investigate students' awareness of radiation exposures and risks. An anonymous multiple-choice cross-sectional questionnaire was distributed to final year medical students to assess knowledge of radiation from common diagnostic examinations and radiation-related risks following completion of the longitudinal radiology curriculum, carried out over the four years of medical training. Sixty-three of 192 eligible students participated (33% response rate). The majority felt that knowledge of radiation doses of common imaging examinations is somewhat or very important; however, only 12% (N = 8) routinely discuss radiation-related risks with patients. While all respondents recognized children as most sensitive to the effects of radiation, only 24% (N = 15) correctly identified gonads as the most radiation-sensitive tissue. Almost all respondents recognized ultrasound and MRI as radiation free modalities. Respondents who correctly identified the relative dose of common imaging examinations in chest x-ray equivalents varied from 3-77% (N = 2 - 49); the remaining responses were largely underestimates. Finally, 44% (N = 28) correctly identified the excess risk of a fatal cancer from an abdominal CT in an adult, while the remainder underestimated this risk. Medical students acknowledge the importance of radiation-related issues to patient care. While almost all students are familiar with radiation-free modalities, many are not familiar with, and commonly underestimate, the relative doses and risks of common imaging studies. This may expose patients to increasing imaging investigations and exposure to radiation hazards.

    Full Text Available Abstract Background The college environment offers great opportunity for HIV high-risk behaviors, including unsafe sex and multiple partnerships. While the overall incidence of HIV infection has seen some decline in recent years, rates of HIV infection among young adults have not seen a proportionate decline. As in the general population, African American young adults have been disproportionately affected by the HIV/AIDS epidemic. This study examined the sexual risk behaviors and perception of HIV risk of students in a predominantly African American commuter urban university in the Midwest. Methods Students enrolled in randomly selected general education courses completed a paper and pencil survey. Data were collected in Fall 2007, and univariate, bivariate, and multivariate analyses were conducted using SPSS for Windows v.16. Results The sample included 390 students, the majority (83% of whom were never married and 87% were sexually experienced. Among males reporting male partnerships those who used marijuana (OR = 17.5, p = 0.01 and those who used alcohol along with illegal drugs (OR = 8.8, p = 0.03 were significantly more likely to report multiple partnerships. Among females reporting male partnerships, those 30 years and older were significantly less likely (OR = 0.09, p = 0.03 to report having multiple male partners. There were significant differences in condom use last sex (p = 0.01 and consistent condom use (p = 0.002 among the different age groups. Older students were less likely to report condom use. Females age 30 years and older (OR = 3.74, p = 0.05 and respondents age 20–29 years (OR = 2.41, p = 0.03 were more likely to report inconsistent condom use than those below 20 years. Marijuana use was correlated with inconsistent condom use (p = 0.02 and alcohol with not using condom last sex among females. Perception of HIV risk was generally poor with 54% of those age 30 years and older, 48.1% of 20–29 year olds, and 57.9% of those

    Q fever is an occupational risk for veterinarians, however little is known about the risk for veterinary medicine students. This study aimed to assess the seroprevalence of Coxiella burnetii among veterinary medicine students and to identify associated risk factors. A cross-sectional study with questionnaire and blood sample collection was performed among all veterinary medicine students studying in The Netherlands in 2006. Serum samples (n = 674), representative of all study years and study directions, were analyzed for C. burnetii IgG and IgM phase I and II antibodies with an immunofluorescence assay (IFA). Seropositivity was defined as IgG phase I and/or II titer of 1:32 and above. Of the veterinary medicine students 126 (18.7%) had IgG antibodies against C. burnetii. Seropositivity associated risk factors identified were the study direction 'farm animals' (Odds Ratio (OR) 3.27 [95% CI 2.14-5.02]), advanced year of study (OR year 6: 2.31 [1.22-4.39] OR year 3-5 1.83 [1.07-3.10]) having had a zoonosis during the study (OR 1.74 [1.07-2.82]) and ever lived on a ruminant farm (OR 2.73 [1.59-4.67]). Stratified analysis revealed study direction 'farm animals' to be a study-related risk factor apart from ever living on a farm. In addition we identified a clear dose-response relation for the number of years lived on a farm with C. burnetii seropositivity. C. burnetii seroprevalence is considerable among veterinary medicine students and study related risk factors were identified. This indicates Q fever as an occupational risk for veterinary medicine students.

    Life science classrooms often emphasize the exception to the rule when it comes to teaching genetics, focusing heavily on rare single-gene and Mendelian traits. By contrast, the vast majority of human traits and diseases are caused by more complicated interactions between genetic and environmental factors. Research indicates that students have a deterministic view of genetics, generalize Mendelian inheritance patterns to all traits, and have unrealistic expectations of genetic technologies. The challenge lies in how to help students analyze complex disease risk with a lack of curriculum materials. Providing open access to both content resources and an engaging storyline can be achieved using a "serious game" model. "Touching Triton" was developed as a serious game in which students are asked to analyze data from a medical record, family history, and genomic report in order to develop an overall lifetime risk estimate of six common, complex diseases. Evaluation of student performance shows significant learning gains in key content areas along with a high level of engagement.

    The purpose of this study is to understand how cancer risk behaviors cluster in U.S. college students and vary by race and ethnicity. Using the fall 2010 wave of the National College Health Assessment (NCHA), we conducted a latent class analysis (LCA) to evaluate the clustering of cancer risk behaviors/conditions: tobacco use, physical inactivity, unhealthy diet, alcohol binge drinking, and overweight/obesity. The identified clusters were then examined separately by students' self-reported race and ethnicity. Among 30,093 college students surveyed, results show a high prevalence of unhealthy diet as defined by insufficient fruit and vegetable intake (>95%) and physical inactivity (>60%). The LCA identified behavioral clustering for the entire sample and distinct clustering among Black and American Indian students. Cancer risk behaviors/conditions appear to cluster among college students differentially by race. Understanding how risk behaviors cluster in young adults can lend insight to racial disparities in cancer through adulthood. Health behavior interventions focused on modifying multiple risk behaviors and tailored to students' racial group could potentially have a much larger effect on cancer prevention than those targeting any single behavior.

    Full Text Available Early assessment and management of risk factors is known to have significant impact in preventing cardiovascular disease (CVD and its associated burden. Cardiovascular disease risk assessment and management (CVDRAM is best approached by teamwork across health care professionals. This study aimed at assessing health care students’ (HCSs knowledge about the parameters needed for estimating CVD risk, their self-assessed preparedness/confidence and perceived barriers for the provision of CVDRAM services through a survey administered to third and fourth year pharmacy, medical, and nursing students in Qatar. Although all student cohorst achieved similar knowledge scores, less than half (n = 38, 47% were able to identify all of the six main risk factors necessary to estimate absolute CVD risk, and a third (32% were unable to identify total cholesterol as an independent risk factor necessary to estimate CVD risk. Training on the use of CVD risk assessment tools differed among the three student cohorts. All student cohorts also perceived similar levels of preparedness in CVDRAM. However, pharmacy students reported the highest preparedness/confidence with the use of the latest CVDRAM guidelines. The majority of statements listed under the barriers scale were perceived by the students as being moderate (median score = 3. Poor public acceptance or unawareness of importance of estimating CVD risk was the only barrier perceived as major by nursing students. Future integration of interprofessional educational (IPE activities in the CVDRAM curricula of HCSs may be a suitable strategy to minimize barriers and foster collaborative practice for the provision of CVDRAM services in Qatar.

    Full Text Available Objective: To determine the association between health-risk behaviors and a history of sexual coercion among urban Chinese high school students. Design: A cross-sectional study was performed among 109,754 high school students who participated in the 2005 Chinese Youth Risk Behavior Survey. Data were analyzed for 5,215 students who had experienced sexual intercourse (1,483 girls, 3,732 boys. Multivariate logistic regression was used to determine the relationship between sexual coercion and the related covariates, and data were stratified by gender. Results: Of those students who had had sexual intercourse, 40.9% of the females and 29.6% of the males experienced sexual coercion (p<0.01. When analyses controlled for demographic characteristics, in the study sample, that is, students who had sexual intercourse, drug use (odds ratios [OR], 2.44, attempted suicide (OR, 2.30, physical abuse (OR, 1.74, binge drinking (OR, 1.62, verbal abuse (OR, 1.29, experience of being drunk (OR, 0.68, and smoking of cigarettes (OR, 0.52 were related to a history of sexual coercion. Patterns of health-risk behaviors also differed among female and male students who had experienced sexual coercion. Conclusions: Sexual coercion is associated with health-risk behaviors. Initiatives to reduce the harm associated with sexual coercion among high school students are needed.

    We determined selected risk factors for the metabolic syndrome and assessed the metabolic risk status (using IDF criteria) of third-year physiology students at Stellenbosch University (88 males and 178 females). Outcome measures included anthropometry [body mass index (BMI), waist circumference, waist-to-hip ratio], blood pressure (BP), resting pulse rate, and fasting blood glucose, total cholesterol and triglyceride levels. In addition, students completed a lifestyle questionnaire. A number of gender-based differences were found, with male students displaying a greater incidence of risk factors for the metabolic syndrome: 6% of males versus 3% of females displayed a cluster of three risk factors. Twenty-five per cent of female students (but only 14% of males) exhibited waist circumferences above the accepted range, which was positively correlated, for males and females, with both systolic and diastolic BP, and in females only, also with total cholesterol levels. Male students on average exercised more than their female counterparts, but also exhibited poorer eating habits. Average blood triglyceride levels for both male and female students exceeded the accepted threshold (1.85 +/- 1.62 mmol/l and 2.15 +/- 1.79 mmol/l, respectively). We concluded that metabolic risk factors were evident in a much younger population than commonly expected. Moreover, the gender-specific differences observed may impact on future risk assessment and preventative measures adopted.

    Adenosine-to-inosine (A-to-I) RNA editing, catalysed by ADAR enzymes conserved in metazoans, plays an important role in neurological functions. Although the fine-tuning mechanism provided by A-to-I RNA editing is important, the underlying rules governing ADAR substrate recognition are not well understood. We apply a quantitative trait loci (QTL) mapping approach to identify genetic variants associated with variability in RNA editing. With very accurate measurement of RNA editing levels at 789 sites in 131 Drosophila melanogaster strains, here we identify 545 editing QTLs (edQTLs) associated with differences in RNA editing. We demonstrate that many edQTLs can act through changes in the local secondary structure for edited dsRNAs. Furthermore, we find that edQTLs located outside of the edited dsRNA duplex are enriched in secondary structure, suggesting that distal dsRNA structure beyond the editing site duplex affects RNA editing efficiency. Our work will facilitate the understanding of the cis-regulatory code of RNA editing.

    2013-01-01

    This paper reports on the perceived effectiveness of a program to increase awareness of the health risks of obesity among African-American students. Thirty (n = 30) senior level Bachelor of Science in Nursing students attending a Historically Black College and University (HBCU) took a knowledge test, then participated in an hour-long educational session on obesity. Following the session, the students completed a 10-item post-test to evaluate the effectiveness of the program in increasing awareness of obesity as a risk for heart disease and diabetes. The findings suggested a need to further educate African-American students on the consequences of obesity as well as recommendations to advance the science of personal and family risk awareness in nursing students.

    High failure rates in introductory college science courses, including anatomy and physiology, are common at institutions across the country, and determining the specific factors that contribute to this problem is challenging. To identify students at risk for failure in introductory physiology courses at our open-enrollment institution, an online pilot survey was administered to 200 biology students. The survey results revealed several predictive factors related to academic preparation and prompted a comprehensive analysis of college records of >2,000 biology students over a 5-yr period. Using these historical data, a model that was 91% successful in predicting student success in these courses was developed. The results of the present study support the use of surveys and similar models to identify at-risk students and to provide guidance in the development of evidence-based advising programs and pedagogies. This comprehensive approach may be a tangible step in improving student success for students from a wide variety of backgrounds in anatomy and physiology courses.

    This study aims to determine the risk-taking attitude of students at Islamic Junior High School (MTs) in Bekasi towards learning mathematics. This is a preliminary research to get information about risk taking attitude in order to conduct next research. Data are obtained by providing questionnaires of 20 indicators, which includes be careful in act, having peace of mind, resolute in making decisions and confident in the act. Respondents are as many as 97 students of 7th grade students of MTs and taken with random techniques from two MTs in the city of Bekasi. The research instrument was adopted from DOSPERT developed, adapted to the ability of 7th grade students of MTs. The attitude of risk taking is part of the student's responsibility attitude to the learning of mathematics, either during preparation, process or after learning mathematics. The attitude of risk taking is important to know in order to be trained continuously. Because the trained attitude of risk taking will make students succeed in learning and working later.

    The clustered regularly interspaced short palindromic repeat (CRISPR)/associated protein 9 (Cas9) technology is revolutionizing genome editing approaches. Its high efficiency, specificity, versatility, flexibility, simplicity and low cost have made the CRISPR/Cas9 system preferable to other guided site-specific nuclease-based systems such as TALENs (Transcription Activator-like Effector Nucleases) and ZFNs (Zinc Finger Nucleases) in genome editing of viruses. CRISPR/Cas9 is presently being applied in constructing viral mutants, preventing virus infections, eradicating proviral DNA, and inhibiting viral replication in infected cells. The successful adaptation of CRISPR/Cas9 to editing the genome of Vaccinia virus paves the way for its application in editing other vaccine/vector-relevant orthopoxvirus (OPXV) strains. Thus, CRISPR/Cas9 can be used to resolve some of the major hindrances to the development of OPXV-based recombinant vaccines and vectors, including sub-optimal immunogenicity; transgene and genome instability; reversion of attenuation; potential of spread of transgenes to wildtype strains and close contacts, which are important biosafety and risk assessment considerations. In this article, we review the published literature on the application of CRISPR/Cas9 in virus genome editing and discuss the potentials of CRISPR/Cas9 in advancing OPXV-based recombinant vaccines and vectors. We also discuss the application of CRISPR/Cas9 in combating viruses of clinical relevance, the limitations of CRISPR/Cas9 and the current strategies to overcome them.

    Full Text Available For those interested in audio, basic sound editing skills go a long way. Being able to handle and manipulate the materials can help you take control of your object of study: you can zoom in and extract particular moments to analyze, process the audio, and upload the materials to a server to compliment a blog post on the topic. On a more practical level, these skills could also allow you to record and package recordings of yourself or others for distribution. That guest lecture taking place in your department? Record it and edit it yourself! Doing so is a lightweight way to distribute resources among various institutions, and it also helps make the materials more accessible for readers and listeners with a wide variety of learning needs. In this lesson you will learn how to use Audacity to load, record, edit, mix, and export audio files. Sound editing platforms are often expensive and offer extensive capabilities that can be overwhelming to the first-time user, but Audacity is a free and open source alternative that offers powerful capabilities for sound editing with a low barrier for entry. For this lesson we will work with two audio files: a recording of Bach’s Goldberg Variations available from MusOpen and another recording of your own voice that will be made in the course of the lesson. This tutorial uses Audacity 2.1.2, released January 2016.

    To determine whether student characteristics, lower-extremity kinematics, and strength are risk factors for sustaining lower-extremity injuries in preprofessional contemporary dancers. Prospective cohort study. Codarts University of the Arts. Forty-five first-year students of Bachelor Dance and Bachelor Dance Teacher. At the beginning of the academic year, the injury history (only lower-extremity) and student characteristics (age, sex, educational program) were assessed using a questionnaire. Besides, lower-extremity kinematics [single-leg squat (SLS)], strength (countermovement jump) and height and weight (body mass index) were measured during a physical performance test. Substantial lower-extremity injuries during the academic year were defined as any problems leading to moderate or severe reductions in training volume or in performance, or complete inability to participate in dance at least once during follow-up as measured with the Oslo Sports Trauma Research Center (OSTRC) Questionnaire on Health Problems. Injuries were recorded on a monthly basis using a questionnaire. Analyses on leg-level were performed using generalized estimating equations to test the associations between substantial lower-extremity injuries and potential risk factors. The 1-year incidence of lower-extremity injuries was 82.2%. Of these, 51.4% was a substantial lower-extremity injury. Multivariate analyses identified that ankle dorsiflexion during the SLS (OR 1.25; 95% confidence interval, 1.03-1.52) was a risk factor for a substantial lower-extremity injury. The findings indicate that contemporary dance students are at high risk for lower-extremity injuries. Therefore, the identified risk factor (ankle dorsiflexion) should be considered for prevention purposes.

    Cardiovascular diseases are one of the leading causes of mortality and morbidity worldwide. The atherosclerotic process in the aorta starts in childhood, while atheroclerotic changes of coronary heart vessels start in adolescence. The aim of the study was to evaluate the knowledge of the students attending all four grades of grammar school about the risk factors for cardiovascular disease, with special attention to the risk factors that can be influenced by modification of life-style. Data from the entrance and exit tests were collected from 197 students attending a grammar school in Novi Sad. Chi-square test and Student T-test or Mann-Whitney U test were used to examine the statistical difference between categorized variables and the continuous variables, respectively. The difference between the number of correct answers for all the students on the entrance test and exit test was statistically significant (pgrammar school and after the lectures, the student's knowledge level was increased by 82.3% (p<0.0005). Children and adolescents from Vojvodina and Serbia should be well informed about the cardiovascular disease risk factors and their prevention with special attention paid to the risk factors that can be influenced by changing lifestyle habits.

    Objectives To identify subtypes of adolescent gamblers based on the 10 Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria for pathological gambling and the 9 Diagnostic and Statistical Manual of Mental Disorders, fifth edition criteria for gambling disorder and to examine associations between identified subtypes with gambling, other risk behaviors, and health/functioning characteristics. Methods Using cross-sectional survey data from 10 high schools in Connecticut (N = 3901), we conducted latent class analysis to classify adolescents who reported past-year gambling into gambling groups on the basis of items from the Massachusetts Gambling Screen. Adolescents also completed questions assessing demographic information, substance use (cigarette, marijuana, alcohol, and other drugs), gambling behaviors (relating to gambling formats, locations, motivations, and urges), and health/functioning characteristics (eg, extracurricular activities, mood, aggression, and body mass index). Results The optimal solution consisted of 4 classes that we termed low-risk gambling (86.4%), at-risk chasing gambling (7.6%), at-risk negative consequences gambling (3.7%), and problem gambling (PrG) (2.3%). At-risk and PrG classes were associated with greater negative functioning and more gambling behaviors. Different patterns of associations between at-risk and PrG classes were also identified. Conclusions Adolescent gambling classifies into 4 classes, which are differentially associated with demographic, gambling patterns, risk behaviors, and health/functioning characteristics. Early identification and interventions for adolescent gamblers should be sensitive to the heterogeneity of gambling subtypes. PMID:25275877

  17. Direct Visual Editing of Node Attributes in Graphs

    2016-10-01

    Full Text Available There are many expressive visualization techniques for analyzing graphs. Yet, there is only little research on how existing visual representations can be employed to support data editing. An increasingly relevant task when working with graphs is the editing of node attributes. We propose an integrated visualize-and-edit approach to editing attribute values via direct interaction with the visual representation. The visualize part is based on node-link diagrams paired with attribute-dependent layouts. The edit part is as easy as moving nodes via drag-and-drop gestures. We present dedicated interaction techniques for editing quantitative as well as qualitative attribute data values. The benefit of our novel integrated approach is that one can directly edit the data while the visualization constantly provides feedback on the implications of the data modifications. Preliminary user feedback indicates that our integrated approach can be a useful complement to standard non-visual editing via external tools.

    2014-01-01

    A growing body of literature has emerged describing the risks of extended-duty shifts and sleep deprivation. Worldwide, midwifery organizations have not adopted standards for practitioner or student duty shifts. This project reviews the literature related to extended-duty shifts in an effort to develop evidence-based recommendations for student nurse-midwives/student midwives (SNMs/SMs). A comprehensive literature search was conducted through electronic databases, major journals, and reference lists published in English since January 2001. Primary research studies evaluating sleep deprivation and shift duration were included. Studies that did not include the target population (shift workers) and those that formed conclusions related to extended-duty shifts greater than 30 hours were excluded. In addition, an extensive worldwide review of duty-hour recommendations from more than 300 health care organizations was conducted. A total of 40 studies met the inclusion criteria. Extended-duty shifts (those greater than 12 hours) increased the risk for cognitive and physical functional errors, safety concerns, and decreased quality of life from sleep deprivation. Cognitive function errors included attention lapses, visual tracking errors, decreased mentation and immediate recall, and decreased learning capacity. Physical errors included decreased motor skills and slowed reaction times in clinical simulations. These deficits led to an increased risk of motor vehicle accidents, needle sticks, and performance equivalent to unsafe blood alcohol concentrations. An overall decrease in quality of life and job satisfaction was linked to extended-duty shifts. Seven organizations for medical residents or advanced practice nurses have developed policy statements on duty shifts, with extended-duty shift limitations between 12 and 24 hours. The risks associated with extended-duty shifts may inhibit the development of SNMs/SMs into competent practitioners and place patients at risk. It

    Adenosine to inosine (A-to-I) pre-mRNA editing by the ADAR enzyme family has the potential to increase the variety of the proteome. This editing by adenosine deamination is essential in mammals for a functional brain. To detect novel substrates for A-to-I editing we have used an experimental method...... to find selectively edited sites and combined it with bioinformatic techniques that find stem-loop structures suitable for editing. We present here the first verified editing candidate detected by this screening procedure. We show that Gabra-3, which codes for the alpha3 subunit of the GABA(A) receptor......, is a substrate for editing by both ADAR1 and ADAR2. Editing of the Gabra-3 mRNA recodes an isoleucine to a methionine. The extent of editing is low at birth but increases with age, reaching close to 100% in the adult brain. We therefore propose that editing of the Gabra-3 mRNA is important for normal brain...

    There are many barriers to medical students receiving education about the linkage between nutrition and cancer, including the lack of role models and teachers and insufficient curricular time. We tested the use of a multimedia program as a possible solution to teaching diet-risk assessment and counseling skills. Images of Cancer Prevention, The Nutrition Link is a CD-ROM multimedia program that was developed and evaluated by 147 medical students. Pre-use and post-use surveys, computer log files, and recorded response sessions were used to determine the learner's 1) ease in using the program, 2) attitudes about the treatment of the content, 3) knowledge gain, and 4) attitudes about the role of physicians in nutrition assessment and counseling for cancer risk reduction. Students improved their knowledge of dietary guidelines for cancer risk reduction and made positive changes in their attitudes toward the role of physicians in dietary counseling. However, most students reported that they would not use the program unless it was required that they do so. The multimedia program was successful; it affected students' knowledge and attitudes concerning nutrition as a modifiable risk factor for some cancers. In addition, the design and delivery of the multimedia product was positively reviewed by the students for ease of access, message design, individualized instruction, and flexibility. Despite these favorable ratings, it was not clear that students would use the program unless required to do so.

At present, many systems display fine algebraic expressions, but the edition of such expressions is weak. Systems like Word and FrameMaker place sub-expressions in too many boxes so that many editing actions are not simple, while usual CAS (computer algebra systems) just use a 1D representation for the edition. Furthermore, Edix allows ...

    The current study aims to examine discrepancies in parents' and college students' perceptions of alcohol risk and the role of perceived risk in predicting parents' intentions to discuss alcohol with their child. In total, 246 college student-parent dyads (56.1% female students, 77.2% mothers) were recruited from a mid-size university. Participants completed measures of absolute likelihood, comparative likelihood, and severity of alcohol consequences. In comparison to students, parents perceived the risks of alcohol poisoning (pacademic impairment (pparents rated the majority of alcohol consequences (e.g., passing out, regrettable sexual situation, throwing up) as more severe than students (all psparents tended to be more optimistic than their child about the comparative likelihood of alcohol consequences. After controlling for demographics and past alcohol communication, greater absolute likelihood (β=.20, p=.016) and less confidence in knowledge of student behavior (β=.20, p=.013) predicted greater intentions to discuss alcohol. Providing parents of college students with information about college drinking norms and the likelihood of alcohol consequences may help prompt alcohol-related communication.

    Aims Drunk driving is a major public health concern, but drugged driving has received little attention. This study examines drugged driving and riding with a drugged driver in a college student sample, in terms of prevalence, age-related trends, race/sex differences, overlap with drunk driving, and risk for alcohol and marijuana dependence. Methods Students (N=1194) ages 19 to 22 were interviewed annually for three years about past-year frequency of drugged driving, riding with a drugged/drunk driver, drunk driving, access to a car, and alcohol/drug dependence. Annual follow-up rates were excellent (88% to 91%). Repeated measures analyses were conducted using generalized estimating equations (GEE). Results One in six (17%wt) 19-year-olds with access to a car drove drugged in the past year; prevalence remained stable through age 22. Drugged driving was more prevalent among males (pdrunk (ranges between 47% and 60%). Both drugged and drunk driving were independently associated with increased risk for alcohol dependence, holding constant age, sex, and race. Drunk driving did not add to the risk for marijuana dependence in the context of drugged driving. Conclusions The prevalence of drugged driving is similar to drunk driving among college students. Both are strongly associated with underlying alcohol and drug dependence. Prevention and treatment implications are discussed. PMID:21601379

    Nowadays, Cardiovascular Diseases (CVDs) represents an escalating worldwide public health problem. Providing consistent data on the magnitude and risk factors of CVDs among young population will help in controlling the risks and avoiding their consequences. The objective was to estimate the prevalence of risk factors of Coronary Heart Disease (CHD) among medical students during their clinical clerkship (4th - 6th years). A cross-sectional study was done during the educational year 2012-2013 at King Abdulaziz University (KAU), Jeddah. Ethical standards were followed and a multistage stratified random sample method was used for selection of 214 medical students. Data was collected through an interviewing questionnaire, measurements and laboratory investigations. Both descriptive and analytical statistics were done by SPSS version 21. CHD risk percent in thirty years was calculated using Framingham algorithm for each student, then the risk among all students was determined. The commonest risk factors of CHDs were daily intake of high fat diet (73.4%), physical inactivity (57.9%), overweight/or obesity (31.2%) and daily consumption of fast food (13.1%). Hyper-cholesterolemia (17.2%) and hypertension (9.3%) were also prevalent risk factors. Smoking prevalence was low (2.8%). Males had significantly higher mean scores for most of CHD risk factors compared to females (p Students't test = 4.74, p students was 10.7%, 2.3% and 0.5% for mild, moderate and severe risk, respectively. An alarmingly high prevalence of CHD risk factors was prevailed among medical students, especially among males. However, a low prevalence of smoking may indicate the success of "Smoke-free Campus" program. Screening risk factors of CHD among medical students and implementation of intervention programs are recommended. Programs to raise awareness about CHD risk factors, encourage young adult students to adopt a healthy dietary behavior and promote physical exercise should be initiated.

  11. Genome edited animals: Learning from GM crops?

    Bruce, Ann

    2017-06-01

    Genome editing of livestock is poised to become commercial reality, yet questions remain as to appropriate regulation, potential impact on the industry sector and public acceptability of products. This paper looks at how genome editing of livestock has attempted to learn some of the lessons from commercialisation of GM crops, and takes a systemic approach to explore some of the complexity and ambiguity in incorporating genome edited animals in a food production system. Current applications of genome editing are considered, viewed from the perspective of past technological applications. The question of what is genome editing, and can it be considered natural is examined. The implications of regulation on development of different sectors of livestock production systems are studied, with a particular focus on the veterinary sector. From an EU perspective, regulation of genome edited animals, although not necessarily the same as for GM crops, is advocated from a number of different perspectives. This paper aims to open up new avenues of research on genome edited animals, extending from the current primary focus on science and regulation, to engage with a wider-range of food system actors.

    Perceived risk of harm has long been a key preventive factor for adolescent marijuana use. However, in recent years, perceived risk has decreased markedly and marijuana use has increased only slightly, leading to new questions about their association. This study investigates the magnitude and stability of the US adolescent marijuana risk/use association from 1991 to 2016, overall and by gender and race/ethnicity. Self-reported data on past 12-month marijuana use, perceived risk of regular marijuana use, gender, and race/ethnicity were obtained from 275,768 US 12th grade students participating in the nationally representative Monitoring the Future study. Time-varying effect modeling (TVEM) was used to examine the marijuana risk/use association over time. Both before and after controlling for gender and race/ethnicity, perceived risk was a strong protective factor against adolescent marijuana use. The magnitude of the great risk/use association strengthened for Hispanic students; remained generally stable over time for 12th graders overall, males, females, and White students; and weakened for Black students. The magnitude of the moderate risk/use association strengthened for 12th graders overall, males, females, White and Hispanic students, but did not continue to strengthen for Black students from 2005 onwards. In general, marijuana use prevalence decreased over time within all levels of perceived risk. Perceived risk remains a strong protective factor for adolescent marijuana use, and the protective association for moderate risk (vs. no/slight risk) is actually increasing over time. Results suggest that accurate and credible information on the risks associated with marijuana use should remain a key component of prevention efforts. Copyright © 2017 Elsevier Ltd.

    2008-01-01

    To examine cross-sectional associations between credit card debt, stress, and health risk behaviors among college students, focusing particularly on weight-related behaviors. Random-sample, mailed survey. Undergraduate and graduate students (n = 3206) attending a large public university. Self-reported health indicators (e.g., weight, height, physical activity, diet, weight control, stress, credit card debt). More than 23% of students reported credit card debt > or = $1000. Using Poisson regression to predict relative risks (RR) of health behaviors, debt of at least $1000 was associated with nearly every risk indicator tested, including overweight/obesity, insufficient physical activity, excess television viewing, infrequent breakfast consumption, fast food consumption, unhealthy weight control, body dissatisfaction, binge drinking, substance use, and violence. For example, adjusted RR [ARR] ranged from 1.09 (95% Confidence interval [CI]: 1.02-1.17) for insufficient vigorous activity to 2.17 (CI: 0.68-2.82) for using drugs other than marijuana in the past 30 days. Poor stress management was also a robust indicator of health risk. University student lifestyles may be characterized by a variety of coexisting risk factors. These findings indicate that both debt and stress were associated with wide-ranging adverse health indicators. Intervention strategies targeting at-risk student populations need to be tailored to work within the context of the many challenges of college life, which may serve as barriers to healthy lifestyles. Increased health promotion efforts targeting stress, financial management, and weight-related health behaviors may be needed to enhance wellness among young adults.

    To understand the prevalence and risk factors for suicidal ideation among college students and to provide a scientific basis for promoting psychological health and suicide prevention. 623 college students at Central South University were selected using stratified cluster sampling and administered a suicide ideation questionnaire, a Symptom Check List (SCL-90), an Adolescent Self-Rating Life Events Check List (ASLEC), a Social Support Rating Scale (SSRS) and a questionnaire about background information. Multivariate logistic regression analysis was employed to identify risk factors for suicide ideation. One year prior to our investigation, 14.6% of respondents had suicide ideation, 2.5% had made a specific suicide plan, and 1.8% had made a suicide attempt. The main risk factors for suicide ideation were dissatisfaction with the selected major of study, limited social support, recent negative life events and depressive tendency. The prevalence of suicide ideation among these college students was high. Appropriate measures focusing on the risk factors identified in this study should be urgently developed to prevent suicides in college students.

    The research review synthesizes the knowledge base on risk and protective factors for dating violence while highlighting its relevance to violence against college women. In particular, the review highlights the personal, family, relationship, and behavioral factors that heighten the risk of dating violence victimization and perpetration while also noting the methodological limitations of the current body of empirical research and identifying directions for future academic work. Researchers have identified the correlation between risky health and behavioral factors and dating violence, most often modeling these as part of the etiology of dating violence among college students. Less often have scholars explored these as co-occurring risk factors. This approach to dating violence may be used to develop meaningful and impactful interventions to reduce the incidence and prevalence of college dating violence while also addressing the other health risk behaviors that impact academic success and place students' well-being at risk. © The Author(s) 2014.

    To determine the prevalence of asthenopia and identify any associated risk factors in the college students in Xi'an, China. From April to September 2012, 1 500 students from five universities in Xi'an were selected according to a multi-stage stratified cluster sampling method. Data on demographic features, lifestyle or dietary habits, health status, living environment conditions, sleep and mental status, and asthenopia symptoms were collected through a self-administered validated questionnaire. Univariate logistic regression and multivariate logistic regression analysis modified by the factor analysis were performed to evaluate risk factors for asthenopia. Fifty-seven percent of the college students complained of asthenopia. Statistically significant risk factors for asthenopia in the univariate analysis included 13 variables. Multivariate analysis revealed a significant relationship between the use of computer and asthenopia (OR 1.21, 95%CI: 1.09 to 1.35). Good sleep and mental status (OR 0.86, 95%CI: 0.76 to 0.97), good living environment conditions (OR 0.67, 95%CI: 0.60 to 0.76), and high intake of green leafy vegetables (OR 0.89, 95%CI: 0.80 to 0.98) were found to be strong predictors of decreasing the occurrence of asthenopia complaints. Asthenopia symptom appears to be common among college students; and it is strongly associated with computer use, psychosocial state, environment conditions and dietary habits, suggesting that additional studies are warranted to verify these risk factors and establish prevention guidelines, especially for college students.

    Farmers are at high risk of occupational skin diseases which may start already during vocational training. This study was aimed at identification of risk factors for work-related skin diseases among vocational students of agriculture. The study involved 440 students (245 males, 195 females aged 17-21 years) in 11 vocational schools which were at least 100 km from each other. The protocol included a physician-managed questionnaire and medical examination, skin prick tests, patch tests, total IgE and Phadiatop. Logistic regression model was used for the identification of relevant risk factors. Work-related dermatoses were diagnosed in 29 study participants (6.6%, 95%CI: 4.3-8.9%): eczema in 22, urticaria in 14, and co-existence of both in 7 students. Significant risk factors for work-related eczema were: history of respiratory allergy (OR=10.10; pagriculture. Atopy, past history of asthma, allergic rhinitis, and eczema (either atopic, allergic or irritant) are relevant risk factors for work-related eczema and urticaria in young farmers, along with family history of any skin disease. Positive skin prick tests seem relevant, especially in the case of urticaria. Asking simple, aimed questions during health checks while enrolling students into agricultural schools would suffice to identify students at risk for work-related eczema and urticaria, giving them the chance for selecting a safer profession, and hopefully avoiding an occupational disease in the future.

    2016-01-01

    Assuming that suicide is the result of a series of factors acting cumulatively, the aim of this paper was to study the association of self-esteem, resilience and locus of control with the risk of suicidal behavior in a sample of nursing students. Observational, cross-sectional and correlational study with 186 nursing students who answered a questionnaire that contained, in addition to demographic data, the Spanish forms of Rosenberg self-esteem scale, the brief resilient coping scale, the Plutchik scale of suicide risk and the Rotter's internal-external locus of control scale. The scores of males and females are very similar on all scales except Locus of Control, where a significantly greater tendency of females attributed to external control. 6.4% of students have scores indicating suicide risk. Suicide risk scores correlated negatively and significantly with self-esteem and resilience and positively with locus of control. The multiple linear regression analysis identified self-esteem as the main variable related to suicide risk. The results suggest that students who have low self-esteem, have difficulty in adjusting to adverse situations and tend to the external attribution of the consequences of their actions may have an increased risk of suicidal behavior. Furthermore, the identification of self-esteem as the important factor involved in suicide risk can help in designing prevention programs. Copyright © 2016 Elsevier España, S.L.U.

    Psychological distress and suicidal behavior are important mental health problems among university students and warrant research to inform strategies for effective prevention in this young population. The present study aimed to assess psychological distress and suicidal behavior and to unravel their associations among university students. A total of 5972 undergraduate students, randomly selected from six universities in central China, comprised the sample. The Chinese version of the Symptom Checklist-90-revised (SCL-90-R) was used to assess various psychological symptoms. Logistic regression analysis was used to examine the relationship between psychological distress and risk for suicidal behavior. 40.7% of the university students reported positive in a least one of the 9 psychological symptom dimensions assessed by the SCL-90-R. 7.6% of the students reported suicidal behavior in the previous twelve months. The risk of suicidal behavior was significantly associated with psychological symptoms of all types, but there were notable differences by sex. For male students, depression and phobic anxiety increased the risk of suicidal behavior. Meanwhile, depression and obsessive-compulsiveness were positively associated with suicidal behavior in female students. Furthermore, increasing risk of suicidal behavior was associated with increasing positive symptom total (PST) score and a statistically significant trend was observed. Data collected from a cross-sectional survey does not allow any examination of causal inference. Psychological distress and suicidal behavior were both common among university students; and psychological distress was highly associated with suicidal behavior. The findings underscore the importance of mental health care for university students. Copyright © 2017 Elsevier B.V. All rights reserved.

    The clustered regularly interspaced short palindromic repeat (CRISPR)/associated protein 9 (Cas9) technology is revolutionizing genome editing approaches. Its high efficiency, specificity, versatility, flexibility, simplicity and low cost have made the CRISPR/Cas9 system preferable to other guided site-specific nuclease-based systems such as TALENs (Transcription Activator-like Effector Nucleases) and ZFNs (Zinc Finger Nucleases) in genome editing of viruses. CRISPR/Cas9 is presently being applied in constructing viral mutants, preventing virus infections, eradicating proviral DNA, and inhibiting viral replication in infected cells. The successful adaptation of CRISPR/Cas9 to editing the genome of Vaccinia virus paves the way for its application in editing other vaccine/vector-relevant orthopoxvirus (OPXV) strains. Thus, CRISPR/Cas9 can be used to resolve some of the major hindrances to the development of OPXV-based recombinant vaccines and vectors, including sub-optimal immunogenicity; transgene and genome instability; reversion of attenuation; potential of spread of transgenes to wildtype strains and close contacts, which are important biosafety and risk assessment considerations. In this article, we review the published literature on the application of CRISPR/Cas9 in virus genome editing and discuss the potentials of CRISPR/Cas9 in advancing OPXV-based recombinant vaccines and vectors. We also discuss the application of CRISPR/Cas9 in combating viruses of clinical relevance, the limitations of CRISPR/Cas9 and the current strategies to overcome them. PMID:29361752

To facilitate the diagnostic use of these measures in the clinical decision-making process, this article provides information on education-stratified, directional prevalence rates (i.e., base rates) of discrepancy scores between the major index scores for the WAIS-III, the WMS-III, and between the WAIS-III and WMS-III. To illustrate how such base-rate data can be clinically used, this article reviews the relative risk (i.e., odds ratio) of empirically defined "rare" cognitive deficits in 2 of the clinical samples presented in the WAIS-III--WMS-III Technical Manual (The Psychological Corporation, 1997).

    This year-long, quasi-experimental study investigated the impact of the use of netbook computers and interactive science software on fifth-grade students' science learning processes, academic achievement, and interest in further science, technology, engineering, and mathematics (STEM) study within a linguistically diverse school district in California. Analysis of students' state standardized science test scores indicated that the program helped close gaps in scientific achievement between at-risk learners (i.e., English learners, Hispanics, and free/reduced-lunch recipients) and their counterparts. Teacher and student interviews and classroom observations suggested that computer-supported visual representations and interactions supported diverse learners' scientific understanding and inquiry and enabled more individualized and differentiated instruction. Finally, interviews revealed that the program had a positive impact on students' motivation in science and on their interest in pursuing science-related careers. This study suggests that technology-facilitated science instruction is beneficial for improving at-risk students' science achievement, scaffolding students' scientific understanding, and strengthening students' motivation to pursue STEM-related careers.

    Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students at risk of later psychiatric events. Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves for unadjusted associations and multivariable cause-specific Cox proportional hazard analyses for adjusted hazard ratios (HRs). We identified 12,147 healthy students with exam-related beta-blocker use and 12,147 matched healthy students with no current or prior use of beta-blockers (median age, 19 years; 80.3% women). Among all healthy students, 0.14% had a first-time prescription for a beta-blocker during the exam period with the highest proportion among students aged 19 years (0.39%). Eighty-one percent of the students filled only that single prescription for a beta-blocker during follow-up. During follow-up, 2225 (18.3%) beta-blocker users and 1400 (11.5%) nonbeta-blocker users were prescribed an antidepressant (p beta-blocker users and 658 (5.4%) nonbeta-blocker users were prescribed a psychotropic drug (p beta-blocker users and 6 (0.05%) nonbeta-blocker users attempted suicide (p = 0.03).

    Full Text Available Objective. To examine risk taking behaviours associated with alcohol consumption amongst UK undergraduate students. Design and Methods. A cross-sectional web survey was used to assess attitudes and health behaviours. The survey included the Alcohol Use Disorders Identification Test (AUDIT. Students were also asked about why they drank alcohol; about their preferred alcoholic beverage; and if they had experienced any consequences associated with drinking alcohol as well as questions relating to sexual risk taking, drug use, and smoking. Results. 2779 (65% female; 84% White British students completed some part of the survey. Of these, 98% (n=2711 completed the AUDIT. Of the 92% that drank 66% (n=1,643 were categorised as being AUDIT positive. 8% (n=224 were categorised as probably alcohol dependent. Higher AUDIT scores were significantly associated with negative consequences such as unplanned sexual activity, physical injuries, and arguments. Other risk taking behaviours such as drug use and smoking were also found to be positively correlated with higher AUDIT scores; drug use; and smoking. Conclusions. The results from this study provide insight into students’ alcohol consumption and associated risk taking. University policies need to protect students’ overall health and wellbeing to ensure academic potential is maximised.

    The emergence of new gene-editing technologies is profoundly transforming human therapeutics, agriculture, and industrial biotechnology. Advances in clustered regularly interspaced short palindromic repeats (CRISPR) have created a fertile environment for mass-scale manufacturing of cost-effective products ranging from basic research to translational medicine. In our analyses, we evaluated the patent landscape of gene-editing technologies and found that in comparison to earlier gene-editing techniques, CRISPR has gained significant traction and this has established dominance. Although most of the gene-editing technologies originated from the industry, CRISPR has been pioneered by academic research institutions. The spinout of CRISPR biotechnology companies from academic institutions demonstrates a shift in entrepreneurship strategies that were previously led by the industry. These academic institutions, and their subsequent companies, are competing to generate comprehensive intellectual property portfolios to rapidly commercialize CRISPR products. Our analysis shows that the emergence of CRISPR has resulted in a fivefold increase in genome-editing bioenterprise investment over the last year. This entrepreneurial movement has spurred a global biotechnology revolution in the realization of novel gene-editing technologies. This global shift in bioenterprise will continue to grow as the demand for personalized medicine, genetically modified crops and environmentally sustainable biofuels increases. However, the monopolization of intellectual property, negative public perception of genetic engineering and ambiguous regulatory policies may limit the growth of these market segments.

    The aim of this study was to evaluate the positive predictive value (PPV) and the diagnostic performance of the ultrasonographic descriptors in the fifth edition of BI-RADS, comparing with the fourth edition using video clips. From September 2013 to July 2014, 80 breast masses in 74 women (mean age, 47.5±10.7 years) from five institutions of the Korean Society of Breast Imaging were included. Two radiologists individually reviewed the static and video images and analyzed the images according to the fourth and fifth edition of BI-RADS. The PPV of each descriptor was calculated and diagnostic performances between the fourth and fifth editions were compared. Of the 80 breast masses, 51 (63.8%) were benign and 29 (36.2%) were malignant. Suspicious ultrasonographic features such as irregular shape, non-parallel orientation, angular or spiculated margins, and combined posterior features showed higher PPV in both editions (all P<0.05). No significant differences were found in the diagnostic performances between the two editions (all P>0.05). The area under the receiver operating characteristics curve was higher in the fourth edition (0.708 to 0.690), without significance (P=0.416). The fifth edition of the BI-RADS ultrasound lexicon showed comparable performance to the fourth edition and can be useful in the differential diagnosis of breast masses using ultrasonography

    Trevisan, Marta; Palù, Giorgio; Barzon, Luisa

    2017-11-01

    Genome editing by programmable nucleases represents a promising tool that could be exploited to develop new therapeutic strategies to fight infectious diseases. These nucleases, such as zinc-finger nucleases, transcription activator-like effector nucleases, clustered regularly interspaced short palindromic repeat (CRISPR)-CRISPR-associated protein 9 (Cas9) and homing endonucleases, are molecular scissors that can be targeted at predetermined loci in order to modify the genome sequence of an organism. Areas covered: By perturbing genomic DNA at predetermined loci, programmable nucleases can be used as antiviral and antimicrobial treatment. This approach includes targeting of essential viral genes or viral sequences able, once mutated, to inhibit viral replication; repurposing of CRISPR-Cas9 system for lethal self-targeting of bacteria; targeting antibiotic-resistance and virulence genes in bacteria, fungi, and parasites; engineering arthropod vectors to prevent vector-borne infections. Expert commentary: While progress has been done in demonstrating the feasibility of using genome editing as antimicrobial strategy, there are still many hurdles to overcome, such as the risk of off-target mutations, the raising of escape mutants, and the inefficiency of delivery methods, before translating results from preclinical studies into clinical applications.

    Full Text Available The paper examines the potential of a social-emotional learning (SEL programme, Promoting Alternative Thinking Strategies (PATHSin Northern Ireland (NI, to prepare at-risk students to succeed in education and later life. At-risk students are defined as students living in communities traditionally divided and fractured by social, religious, cultural intolerance, and sectarianism. The risk is not developing the social-emotional competencies necessary for good emotional health and positive relationships that are often necessary for personal and academic achievement. Themes of freedom, education and development are explored in reference to findings from a matched randomised control evaluation of PATHS implemented in six primary schools in Northern Ireland between 2008 and 2011. Results of data obtained through individual student assessments of social-emotional skills and findings from interviews with school principals, teachers and students are reported, and the potential of SEL as a vehicle for at-risk students to succeed are discussed. Findings from the evaluation clearly demonstrate how SEL provides a potential vehicle for breaking down the constraints and barriers to personal development and success for at-risk students. Recommendations are made for the further development and implementation of SEL programmes in Europe to advance the opportunities for at-risk students in divided communities to succeed.

    Full Text Available AIM:To determine the prevalence of asthenopia and identify any associated risk factors in the college students in Xi’an, China.METHODS:From April to September 2012, 1 500 students from five universities in Xi’an were selected according to a multi-stage stratified cluster sampling method. Data on demographic features, lifestyle or dietary habits, health status, living environment conditions, sleep and mental status, and asthenopia symptoms were collected through a self-administered validated questionnaire. Univariate logistic regression and multivariate logistic regression analysis modified by the factor analysis were performed to evaluate risk factors for asthenopia.RESULTS:Fifty-seven percent of the college students complained of asthenopia. Statistically significant risk factors for asthenopia in the univariate analysis included 13 variables. Multivariate analysis revealed a significant relationship between the use of computer and asthenopia (OR 1.21, 95%CI:1.09 to 1.35. Good sleep and mental status (OR 0.86, 95%CI:0.76 to 0.97, good living environment conditions (OR 0.67, 95%CI:0.60 to 0.76, and high intake of green leafy vegetables (OR 0.89, 95%CI:0.80 to 0.98 were found to be strong predictors of decreasing the occurrence of asthenopia complaints.CONCLUSION:Asthenopia symptom appears to be common among college students; and it is strongly associated with computer use, psychosocial state, environment conditions and dietary habits, suggesting that additional studies are warranted to verify these risk factors and establish prevention guidelines, especially for college students.

    Full Text Available OBJECTIVE: To compare the prevalence of major risk and protection factors for chronic non-communicable diseases in school-aged children in Brazilian capitals surveyed in the National Adolescent School-based Health Survey in its two editions, 2009 and 2012. METHODS: The frequencies, with Confidence Interval of 95%, of the following demographic variables were compared: food intake, body image, physical activity, smoking, alcohol and other drugs. Prevalence was compared in the two editions of the survey. RESULTS: The proportion of students who attend two physical education classes a week was maintained at 49% between 2009 and 2012, increasing in public schools from 50.6% (95%CI 49.8 - 51.4 to 52.5% (95%CI 49.2 - 55.7, and decreasing in private schools. There was no change in the proportion of students who watch two hours or more of television daily, about 80%. As for body image, there was no change between the two editions, and about 60% considered themselves being of normal weight. There was a reduction in the percentage of adolescents who experienced cigarettes, from 24.2% (95%CI 23.6 - 24.8 to 22.3% (95%CI 21.4 - 23.2, and the prevalence of smoking was maintained at about 6% (there was no statistical difference between 2009 and 2012. The consumption of beans, fruits, sweets and soft drinks also decreased. Frequency of drug experimentation was of 8.7% (95%CI 8.3 - 9.1 in 2009, and 9.6% (95%CI 9.0 - 10.3 in 2012, with no difference between confidence intervals, and the frequency of alcohol experimentation was maintained at about 70%; the percentage of use in the past 30 days was also maintained at around 27%. CONCLUSION: In the Brazilian capitals, the vast majority of prevalence of risk factors were kept stable in the two editions of the National Survey of School. These data generate evidence to guide the implementation of public policies to minimize the exposure of adolescents to risk factors.

    2008-01-01

    Although a variety of radiation-related education courses are provided in universities, information on faculty and student perceptions of radiation risk is limited. To obtain quantitative data on this issue, we conducted a written questionnaire survey at Nagasaki University on the perceived risks of 13 health hazards, of which six related to radiation exposure. The respondents were asked to estimate the risk of the various items to health on a rating scale of 1 to 5. 'Living near a nuclear plant' received the highest rating of 4, followed by 'not using solar UV protection in midsummer'. 'X-ray diagnostic tests' were rated at only 2, which was lower than the rating for 'air travel'. Among the respondents, undergraduate students showed the highest average risk rating across all items followed by nurses, and staff and graduate students, with doctors and dentists producing the lowest scores. These results suggest that level of specialist knowledge is associated with risk perception, and therefore that radiation education should be carefully planned to improve levels of understanding.

Results The total number of 35 (out of 100 students had a tattoo, and 67 wished to have a tattoo. There was no statistically significant difference in emotional profile between tattooed and nontattooed individuals, yet the differences were detected when the group of subjects who wanted a tattoo and those who did not want a tattoo were compared. Higher result on the aggression scale of and lower on control scale was gained by those with the wish for tattooing. Students with bigger tattoos (23 showed higher score on depression scale. Students in the tattooed group more frequently abused drugs and committed traffic offences compared to the students in non-tattooed group. Conclusion Results of this research as well as previous research show that the presence of a tattoo could be a rough indicator for possible emotional problems and risk behaviour, which could have significant implications in preventing these behaviours. Future studies are required on a larger and more representative sample as well as to clarify why young people decide to be tattooed.

    Full Text Available Students with chronic illness are at risk for a host of academic and social problems. The risk is exacerbated when students are unable to attend school short term or long term due to medical problems. Educators may be able to reduce academic and social risk for students with chronic illness through effective homebound instruction. However, there remain many barriers to effective homebowund instruction. Effective interdisciplinary and community coordination, development of policies, teacher support, inclusion of families, and use of technology can be combined to overcome these barriers and create effective homebound programs and policies. The result is reduced risk for the large and vulnerable population of students with chronic illness.

    The number of American study abroad students increased more than 150% in the past decade, along with growth in destinations with increased health risks. This study investigated travel health risk perceptions and prevention behaviors to guide interventions that address the emerging health needs of US study abroad students. A cross-sectional design was used to collect data from 318 American study abroad students using a Web-based survey. The primary source of travel health information was youth-oriented travel guidebooks (85%). The grand mean risk perception score for 18 travel health threats was 1.7 on a 1 to 4 scale, with top-rated threats being contaminated food/water, psychological distress, personal assault, and excessive sun exposure. Predeparture advice was received from primary care providers (52%) and travel health specialists (18%). Additional prevention measures were vaccines (42%) and medication (24%). Of 114 students listing their travel vaccinations, 11% described receiving a malaria vaccine and 4% a hepatitis C vaccine, although no such vaccines exist. Most respondents were confident/very confident in their ability to engage in prevention behaviors (94%). Health problems were primarily infectious disease (70%), psychological distress (10%), and injuries (8%). When asked if prior travel destinations involved areas where malaria transmission occurs, 20% responded, "Don't know." Identified gaps in travel health knowledge and prevention behaviors may produce hazardous consequences when combined with low-perceived risk, reliance on travel guidebooks for health information, and high ratings for prevention self-efficacy. Future research is needed to test the effectiveness of educational interventions designed for student travelers who would benefit from guided practice with destination-specific risk appraisal and prevention planning. Web-based educational resources are a good fit for this population because they are easily updated, available in all phases of

    The editorial process is analyzed, and five levels of edit are identified. These levels represent cumulative combinations of nine types of edit: (1) coordination, (2) policy, (3) integrity, (4) screening, (5) copy clarification, (6) Mechanical Style, (7) Language, and (9) substantive. The levels and types of edit, although developed for specific use with external reports at the Jet Propulsion Laboratory, cover the general range of technical editing, especially as it applies to an in-house technical publications organization. Each type of edit is set forth in terms of groups of actions to be performed by the editor. The edit-level concept has enhanced understanding and communication among editors, authors, and publications managers concerning the specific editorial work to be done on each manuscript. It has also proved useful as a management tool for estimating and monitoring cost.

    Depressive disorders in adolescents and young adults may have serious developmental and functional consequences, such as academic failure or persistent psychosocial problems. University students are affected by specific agents which may play a role in the onset of depression. The problem of student depression is particularly important in Poland because of a recent increase in student numbers, therefore, the aim of the presented study was to evaluate the prevalence of the risk of depression and suicidal thoughts among university students in Poznan, Poland, and to analyze the role of gender, current living arrangements, background (rural/small town or urban permanent place of residence), and reported financial status. 1,065 respondent students, mean age 21.1 years, 72% of whom were females, anonymously answered a questionnaire on the risk of depression (Kutcher's KADS) and a demographics survey. The obtained data were then analyzed statistically with the SPSS programme. 6.1 subjects were at risk of depression while 1.6 % of them had suicidal thoughts. Among analyzed determinants, perceived financial status and student's background (permanent place of residence) were found to have a statistically significant influence on the risk of depression. Students with rural/small town background and/or lower rather than good reported financial status are more likely to become depressed.

    Full Text Available Purpose The aim of this study was to evaluate the positive predictive value (PPV and the diagnostic performance of the ultrasonographic descriptors in the fifth edition of BI-RADS, comparing with the fourth edition using video clips. Methods From September 2013 to July 2014, 80 breast masses in 74 women (mean age, 47.5±10.7 years from five institutions of the Korean Society of Breast Imaging were included. Two radiologists individually reviewed the static and video images and analyzed the images according to the fourth and fifth edition of BI-RADS. The PPV of each descriptor was calculated and diagnostic performances between the fourth and fifth editions were compared. Results Of the 80 breast masses, 51 (63.8% were benign and 29 (36.2% were malignant. Suspicious ultrasonographic features such as irregular shape, non-parallel orientation, angular or spiculated margins, and combined posterior features showed higher PPV in both editions (all P0.05. The area under the receiver operating characteristics curve was higher in the fourth edition (0.708 to 0.690, without significance (P=0.416. Conclusion The fifth edition of the BI-RADS ultrasound lexicon showed comparable performance to the fourth edition and can be useful in the differential diagnosis of breast masses using ultrasonography.

    Full Text Available Background/Aim. Cardiovascular diseases are a leading cause of death in the majority of developed, as well as in many developing countries. The aim of this study was to determine cardiovascular risk factors in student population and to suggest possible measures for prevention. Methods. The study was carried out during 2007-2008 at the School of Medicine, University of Niš. It included 824 students in their final year (220 males, 604 females. Results. There was no significant difference in prevalence of hypertension among the male (1.81% and female students (0%. The prevalence of obesity (Body Mass Index - BMI > 30 kg/m2 was significantly higher (p < 0.001 in the male (7.27% than in the female population (1.32%. Abdominal obesity was also more frequently encountered (p < 0.01 in the male (9.09% than in female population (1.32%. Every fourth student smoked cigarettes with no significant difference between the male and female students. Alcohol consumption was a significantly higher problem (p < 0.001 in the male population (18.18% than in the female one (2.65%. Physical inactivity was more often found (p < 0.001 in the female students (65.56%, than in male ones (36.36%. By the bivariate correlation of cardiovascular risk factors, it was determined that in the male student population systolic blood pressure correlated significantly with diastolic blood pressure, BMI and waist size, whereas age correlated with sistolic blood pressure, waist size and smoking. In the female students sistolic blood pressure correlated with diastolic blood pressure, BMI and waist size; diastolic blood pressure correlated with BMI and physical inactivity; cigarette smoking correlated with alcohol consumption and age. Conclusion. Cardiovascular risk factors are present in the final-year students of the School of Medicine, University of Niš. It is necessary to insist on decreasing obesity prevalence, cigarette and alcohol consumption, and on increasing physical activity

    Insufficient sleep is common among high school students and has been associated with an increased risk for motor vehicle crashes (1), sports injuries (2), and occupational injuries (3). To evaluate the association between self-reported sleep duration on an average school night and several injury-related risk behaviors (infrequent bicycle helmet use, infrequent seatbelt use, riding with a driver who had been drinking, drinking and driving, and texting while driving) among U.S. high school students, CDC analyzed data from 50,370 high school students (grades 9-12) who participated in the national Youth Risk Behavior Surveys (YRBSs) in 2007, 2009, 2011, or 2013. The likelihood of each of the five risk behaviors was significantly higher for students who reported sleeping ≤7 hours on an average school night; infrequent seatbelt use, riding with a drinking driver, and drinking and driving were also more likely for students who reported sleeping ≥10 hours compared with 9 hours on an average school night. Although insufficient sleep directly contributes to injury risk, some of the increased risk associated with insufficient sleep might be caused by engaging in injury-related risk behaviors. Intervention efforts aimed at these behaviors might help reduce injuries resulting from sleepiness, as well as provide opportunities for increasing awareness of the importance of sleep.

    Many adolescents engage in risk behaviors such as substance use and aggression that jeopardize their healthy development. This study tested the hypothesis that an authoritative school climate characterized by strict but fair discipline and supportive teacher-student relationships is conducive to lower risk behavior for high school students. Multilevel logistic regression models were used to analyze cross-sectional, student-report survey data from a statewide sample of 47,888 students (50.6 % female) in 319 high schools. The students included ninth (26.6 %), tenth (25.5 %), eleventh (24.1 %) and twelfth (23.8 %) grade with a racial/ethnic breakdown of 52.2 % White, 18.0 % Black, 13.1 % Hispanic, 5.9 % Asian, and 10.8 % reporting another or two or more race/ethnicities. Schools with an authoritative school climate had lower levels of student-reported alcohol and marijuana use; bullying, fighting, and weapon carrying at school; interest in gang membership; and suicidal thoughts and behavior. These results controlled for demographic variables of student gender, race, grade, and parent education level as well as school size, percentage of minority students, and percentage of low income students. Overall, these findings add new evidence that an authoritative school climate is associated with positive student outcomes.

    Studies show that university students are at risk for eating disorders. However, risk behaviour has not been studied among Danish medical students, nor have the gender differences in risk behaviour been described in a Danish context. All first-year medical students (n = 979) received a questionnaire related to body perception, exercise habits, eating habits, height and weight in the fall of 2006 and 2007. The response rate was 57% (n = 561). The gender distribution of the study population was 71.8% females and 28.2% males and the average age was 21.5 years. More males (89.8%) than females (73.1%) were satisfied with their body and more females (34.8%) than males (10.9%) felt too fat. More females (42.7%) than males (19.9%) felt guilty when eating unhealthy food. 2.3% (all females) claimed to feel anxiety when they were about to eat. More males (48.4%) than females (28.6%) stated that they could not keep themselves from exercising. 13.5% of the underweight females (body mass index eating disorders than male students. Future research in this area should address the causes of such behaviour.

    To clarify sleep disorder risk factors among student athletes, this study examined the relationship between lifestyle habits, competition activities, psychological distress, and sleep disorders. Student athletes (N = 906; male: 70.1%; average age: 19.1 ± 0.8 years) in five university sports departments from four Japanese regions were targeted for analysis. Survey items were attributes (age, gender, and body mass index), sleep disorders (recorded through the Pittsburgh Sleep Quality Index), lifestyle habits (bedtime, wake-up time, smoking, drinking alcohol, meals, part-time jobs, and use of electronics after lights out), competition activities (activity contents and competition stressors), and psychological distress (recorded through the K6 scale). The relation between lifestyle habits, competition activities, psychological distress, and sleep disorders was explored using logistic regression analysis. Results of multivariate logistic regression analysis with attributes as adjustment variables showed that "bedtime," "wake-up time," "psychological distress," "part-time jobs," "smartphone/cellphone use after lights out," "morning practices," and "motivation loss stressors," were risk factors that were independently related to sleep disorders. Sleep disorders among student athletes are related to lifestyle habits such as late bedtime, early wake-up time, late night part-time jobs, and use of smartphones/cellphones after lights out; psychological distress; and competition activities such as morning practices and motivation loss stressors related to competition. Therefore, this study suggests the importance of improving these lifestyle habits, mental health, and competition activities. Copyright © 2017 Elsevier B.V. All rights reserved.

    Recent data demonstrates that the use of e-cigarettes is growing, especially among college students and young adults. This trend is increasingly problematic, as many of these individuals report never using traditional tobacco cigarettes, but nevertheless are using e-cigarettes. The present study sought to develop the Risks and Benefits of E-cigarettes (RABE) questionnaire to assess the perceptions about e-cigarette use among college students. College students (N=734) completed the RABE via online survey. Principal components analysis yielded two reliable scales representing perceptions about e-cigarette use. Based on the two-factor solution, subscales were named according to item content. The resulting 30 items demonstrated excellent internal consistency (Risks scale α=0.92; Benefits scale α=0.89). Subsequent confirmatory factor analysis generally supported the 2-factor structure. As an initial measure of construct validity, scale scores were compared across smoking status groups. Smoking status groups were defined by the following: "e-cigarette users" were current daily users of e-cigarettes, "conventional smokers" were daily traditional cigarette users, and "dual users" were individuals who used both e-cigarettes and traditional cigarettes daily. Scale scores for perceived Benefits of e-cigarette use differed significantly across groups (pe-cigarette use. Scale scores for perceived Risks of e-cigarette use across smoking status groups did not significantly differ. The present results indicate that the RABE is a reliable instrument to measure college student's perceived risks and benefits of e-cigarettes. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2013-12-01

    I read A Journey with Fred Hoyle: The Search for Cosmic Life shortly after the first edition appeared in 2005. The second expanded edition of this remarkable autobiographical account brings the scientific story up to date. The added Epilogue offers reflections in 2012, and shows that some of Hoyle's and Wickramasinghe's heretical theories have become accepted science today: these scientists were among the forerunners of today's astrobiology. The book is the story - presented as a blend of personal anecdotes, travel stories, references to political and social events, and science writing - of the remarkable 40-year friendship and scientific collaboration between the British astrophysicist Fred Hoyle and the Sri Lankan mathematician and astronomer Chandra Wickramasinghe. The author illuminates the story of his collaboration with Hoyle with interesting aspects of his personal life, such as the description of his educational background in Sri Lanka, and the story of how he, as a PhD student, made his first contact with his supervisor in 1960. The book also offers insights into Hoyle's and Wickramasinghe's family lives. The narrative also contains plenty of interstellar astrophysics along with the stories. Sir Fred Hoyle (1915-2001) was famous for his contribution to the theory of stellar nucleosynthesis, renowned for his coining (on BBC radio) of the term Big Bang and for his later rejection of that theory (coupled to his advocacy of the steady state cosmology), and famed as writer of more than a dozen science-fiction stories. He was the founding director of the Cambridge Institute of Theoretical Astronomy (that later became the Institute of Astronomy). Hoyle was a scientific whistleblower, a radical troublemaker, an unorthodox scientific mind, but also a victim of the system. Hoyle-Wickramasinghe thought was a long-term assault on conventional thinking: especially their notable concept of panspermia (that ever-present life pervades our universe) and their opposition to

    Reduction of risk factors of atherosclerosis, lifestyle modification significantly cause the reduction in the incidence, morbidity and mortality of cardiovascular diseases (CVDs). Objective: To evaluate cardiovascular risk factors and analyze the lifestyle of students finishing the first year of studies at selected universities in Krakow. The study was performed in 2015roku. 566 students finishing the first year of study, including 319 (56.4%) men and 247 (43.6%) women were examined. The students were in age from 18 to 27 years, an average of 20.11± 1.15 years. They represented 6 different universities in Cracow. In order to assess eating habits, lifestyle and analysis of risk factors of cardiovascular disease was used method of diagnostic survey using the survey technique. BMI was calculated from anthropometric measurements. The program Statistica 12.0 were used in statistical analysis. The analysis showed that most fruits and vegetables consume UR students and AWF, least of AGH. Only 34.8% of students regularly consume fish of the sea, there were no significant differences between universities. Sports frequently cultivate the students of AWF (93% of the students of this university). Academy of Fine Arts students drink the most coffee. Students of AGH frequently consume alcohol. 60% of all students never tried drugs, but only 25.7% of student of Fine Arts never tried drugs. Overweight occurs in 12.6% of students, and obesity in 1.1%. The most risk factors of atherosclerosis occur in students of AGH and ASP. The results of the study clearly indicate on the necessity of implementation of prevention and improvement of health behaviors in students of AGH and ASP universities.

    This study aims to identify the frequency of risk and protection factors related to drug consumption among undergraduate nursing students. It is a cross-sectional study in which authors applied the instrument Risk and Protection Factors for the Consumption of Psychoactive Substances, validated for use with undergraduate nursing students. Data were analyzed through STATA 10. Three hundred and ninety students participated in the study. The domain "prejudice and appraisal", "social permissiveness and access to psychoactive substances", "social skills and self-control" are risk factors for drugs use in 100% of participants. "Spirituality" and "satisfaction with interpersonal relations" were predominant protective domains. Based on data, authors can conclude that the students did not consider the risks in alcohol and tobacco consumption, as they think it is normal and socially acceptable.

    Alcohol over-use is one of the risk behaviour and has harmful effects on health. In the whole European Region ever forth death among 15-29 years old people is caused by alcohol over. use. The aim of the paper is to present the degree of alcohol consumption propagation among academic stu. dents in Podkarpackie, as well as estimate the occurrence of hazardous drinking. Anonymous questionnaire survey was conducted among academic students in 2010. Chi-square test was used for statistical analysis. There is statistical difference regarding alcohol use between women and men. Men report to drink more and more frequent. Regular alcohol use was declared by 11.9% of men and 2.3% of women. Hazardous drinking was reported by 20.7% students. Age does not statistically differ the occurrence of hazardous drinking. However, it is interesting that although among the group of 19 years old, every seventh student reports hazardous drinking, among the other groups it was reported by every fifth student. More students from urban areas (24%), than from rural areas (18%) report hazardous drinking. Students living in dormitory almost twice more frequent are at the risk of hazardous drinking (29%), than those living with parents (17%). Among female students hazardous drinking was reported by the following faculties: touristic and recreation (24%), law(13%), medical (14%) and mathematic-environmental (15%). Among men students hazardous drinking was highly reported by law and administration faculty students (33%). Among hazardous drinking students as many as 45% regularly smoke cigarettes.

    To find out the frequency of osteopenia and associated risk factors among young female students. Methods: This observational, cross-sectional study was conducted at the Dow University of Health Sciences, Karachi, from August 2011 to January 2012, and comprised young female students. Convenient sampling method was used. Age, residence, sun exposure, menstrual status, level of physical activity, exercise, vitamin D, calcium intake were variables of interest. Dual-energy X-ray absorptiometry scan was used to measure bone mineral density on the lumbar spine, hip, femur and distal forearm. SPSS 16 was used for data analysis. Results: A total of 100(76.9%) students were included in this study. The age range was 20-30 years. Overall,70(70%)participants were osteopenic, while 30(30%) were normal. Age<25 years, living with less exposure to sun, less physical activity and diet low in calcium and vitamin D were common risk factors. Conclusion: The frequency of osteopenia was significantly high among young female students. (author)

    . The book ends with the same appendices as in the first edition (units, formulae, physical constants, examiners' terms, a suggested revision list and notes on examination preparation) plus the two-page synoptic appendix. The second edition with its additional entries on particle physics and astrophysics should prove useful as a study guide to supplement a textbook or as a revision guide as AS or A2 examinations approach. In addition, the concise nature of many of the entries could be valuable in helping physics students sharpen their written communication skills, thereby securing marks which all too often they lose on account of inadequate answers to descriptive questions.

    Zhengleibencao (Classified Materia Medica) had been formed into several kinds of edition systems during its dissemination, among which there was the edition system of Daquanbencao (Complete Collection of Materia Medica). Daquanbencao was originally carved in the Jin dynasty, thereafter it was re-carved in the Yuan, Ming and Qing dynasties so as to form a series of editions such as the edition of Zhenyou in the second year of the Jin dynasty; the edition of the Zongwenshuyuan college in Dade renyan year of the Yuan dynasty; the WANG Qiu's carved edition of Shangyitang hall in the Ming dynasty; the carved edition of Jishanshuyuan, the Jishang mountain college in the Ming dynasty, the reprinted edition of PENG Duan-wu in the Ming dynasty, the supplementary edition of YANG Bi-da in the Qing dynasty;, and the carved edition of KE Feng-shi in the Qing dynasty. Among all the editions, Chongkanjingshizhengleidaquanbencao (Reprinted Classified Daquan Materia Medica from Historical Classics) was the representative one. As a representative of the above editions, the carved edition of WANG took the edition of the Zongwenshuyuan college of the Yuan dynasty as the original edition, but the images picture of materia medica adopted from the edition of Zhenghebencao (Materia Medica of the Zhenghe era).

    Full Text Available Introduction: A 2009 National Academies of Sciences report on child mental health prevention and treatment concluded that screening for mental health risk is an essential component of service delivery. To date, however, there are few practical assessments available or practices in place that measure individual child risk, or risk aggregated at the school or community level. This study examined the utility of a 30-item paper and pencil student self-report screener of behavioral and emotional risk (BER for surveying community risk among 7 schools. Methods: In 2010, 2,222 students in 3 middle and 4 high schools in a medium-sized school district in Georgia were administered the Behavioral and Emotional Screening System Self-Report Child/Adolescent form (BESS Student. The BESS is designed to measure 4 sub-syndromal BER factors for developing mental health disorders: inattention/hyperactivity, internalizing, school problems, and personal adjustment. Analysis of Variance and Chi Square analyses were used to assess the association between adolescent self-reported BER as an indicator of school BER, grade level, child ethnic identification and gender, socioeconomic status, and special education placement status.Results: BESS scores differentiated well between schools for overall BER and special education status, as well as between grade levels, ethnicity, and gender groups. One high school, known by the school administration to have numerous incidents of student behavior problems, had the most deviant 4 BER domain scores of all 7 schools. Girls rated themselves as having a higher prevalence of BER (14% than boys (12%; middle school students reported fewer difficulties than high school students.Conclusion: Middle and high school students were capable of identifying significant differences in their own BER across schools, suggesting that universal mental health risk screening viastudent self-report is potentially useful for identifying aggregated community

    Widening access to medical students from diverse educational backgrounds is a global educational mandate. The impact, on students' generic learning skills profiles, of development programmes designed for students at risk of attrition is unknown. This study investigated the impact of a 12-month Intervention Programme (IP) on the generic learning skills profile of academically-at-risk students who, after failing at the end of the first semester, completed the IP before entering the second semester of a conventional medical training programme. This prospective study surveyed medical students admitted in 2009 and 2010, on entry and on completion of first year, on their reported practice and confidence in information handling, managing own learning, technical and numeracy, computer, organisational and presentation skills. Of 414 first year students, 80 (19%) entered the IP. Levels of practice and confidence for five of the six skills categories were significantly poorer at entry for IP students compared to conventional stream students. In four categories these differences were no longer statistically significant after students had completed the IP; 62 IP students (77.5%) progressed to second year. A 12-month development programme, the IP, effectively addressed generic learning skills deficiencies present in academically-at-risk students entering medical school.

    A single base pair mutation in the genome can result in many congenital disorders in humans. The recent gene editing approach using CRISPR/Cas9 has rapidly become a powerful tool to replicate or repair such mutations in the genome. These approaches rely on cleaving DNA, while presenting unexpected risks. In this study, we demonstrate a modified CRISPR/Cas9 system fused to cytosine deaminase (Cas9-DA), which induces a single nucleotide conversion in the genome. Cas9-DA was introduced into sea urchin eggs with sgRNAs targeted for SpAlx1, SpDsh, or SpPks, each of which is critical for skeletogenesis, embryonic axis formation, or pigment formation, respectively. We found that both Cas9 and Cas9-DA edit the genome, and cause predicted phenotypic changes at a similar efficiency. Cas9, however, resulted in significant deletions in the genome centered on the gRNA target sequence, whereas Cas9-DA resulted in single or double nucleotide editing of C to T conversions within the gRNA target sequence. These results suggest that the Cas9-DA approach may be useful for manipulating gene activity with decreased risks of genomic aberrations.

    Full Text Available Background. Little attention has been paid to the role of poor mental health among young people with regard to HIV risk behaviour and HIV prevention in Africa. Objective. To determine the association between mental health, substance use and HIV sexual risk behaviour among a sample of university students in South Africa. Methods. A cross-sectional survey was conducted among undergraduate students who were recruited conveniently from public campus venues at the University of Limpopo Medical University of Southern Africa (Medunsa campus. The sample included 722 university students (57.6% men and 42.4% women with a mean age of 21.7 years (standard deviation ±8.8. Results. Of the 722 students, 39.5% reported depression, 23.4% screened positive for post-traumatic stress disorder (PTSD, 22% reported hazardous or harmful alcohol use, 33% reported ≥2 sexual partners in the past 12 months, 50% reported inconsistent condom use, 46% reported unknown HIV status of a sexual partner and 20% reported alcohol use in the context of sex in the past 3 months. In multivariate analysis, HIV risk behaviour was associated with, among men, hazardous or harmful alcohol use and having screened positive for PTSD, and among women, being in the 4th or more year of study and current cannabis use. Conclusion. Poor mental health, including substance use, was found to be associated with HIV risk behaviour. Co-ordinated mental health and sexual and reproductive health services that meet the needs of university students would be desirable.

    2013-01-01

    Plant regulatory circuits coordinating nuclear and plastid gene expression have evolved in response to external stimuli. RNA editing is one of such control mechanisms. We determined the Arabidopsis nuclear-encoded homeodomain-containing protein OCP3 is incorporated into the chloroplast, and contributes to control over the extent of ndhB transcript editing. ndhB encodes the B subunit of the chloroplast NADH dehydrogenase-like complex (NDH) involved in cyclic electron flow (CEF) around photosystem I. In ocp3 mutant strains, ndhB editing efficiency decays, CEF is impaired and disease resistance to fungal pathogens substantially enhanced, a process recapitulated in plants defective in editing plastid RNAs encoding NDH complex subunits due to mutations in previously described nuclear-encoded pentatricopeptide-related proteins (i.e. CRR21, CRR2). Furthermore, we observed that following a pathogenic challenge, wild type plants respond with editing inhibition of ndhB transcript. In parallel, rapid destabilization of the plastidial NDH complex is also observed in the plant following perception of a pathogenic cue. Therefore, NDH complex activity and plant immunity appear as interlinked processes. PMID:24204264

    Students at community colleges comprise nearly half of all U.S. college students and show higher risk of heavy drinking and related consequences compared to students at 4-year colleges, but no alcohol safety programs currently target this population. To examine the feasibility, acceptability, and preliminary efficacy of an alcohol risk-reduction program delivered through text messaging designed for community college (CC) students. Heavy drinking adult CC students (N=60) were enrolled and randomly assigned to the six-week active intervention (Text Message Alcohol Program: TMAP) or a control condition of general motivational (not alcohol related) text messages. TMAP text messages consisted of alcohol facts, strategies to limit alcohol use and related risks, and motivational messages. Assessments were conducted at baseline, week 6 (end of treatment) and week 12 (follow up). Most participants (87%) completed all follow up assessments. Intervention messages received an average rating of 6.8 (SD=1.5) on a 10-point scale. At week six, TMAP participants were less likely than controls to report heavy drinking and negative alcohol consequences. The TMAP group also showed significant increases in self-efficacy to resist drinking in high risk situations between baseline and week six, with no such increase among controls. Results were maintained through the week 12 follow up. The TMAP alcohol risk reduction program was feasible and highly acceptable indicated by high retention rates through the final follow up assessment and good ratings for the text message content. Reductions in multiple outcomes provide positive indications of intervention efficacy. Copyright © 2016. Published by Elsevier Ltd.

    Young people are a high risk group for gambling problems and university (college) students fall into that category. Given the high accessibility of gambling in Australia and its association with entertainment, students from overseas countries, particularly those where gambling is restricted or illegal, may be particularly vulnerable. This study examines problem gambling and its correlates among international and domestic university students using a sample of 836 domestic students (286 males; 546 females); and 764 international students (369 males; 396 females) at three Australian universities. Our findings indicate that although most students gamble infrequently, around 5 % of students are problem gamblers, a proportion higher than that in the general adult population. Popular gambling choices include games known to be associated with risk (cards, horse races, sports betting, casino games, and gaming machines) as well as lotto/scratch tickets. Males are more likely to be problem gamblers than females, and almost 10 % of male international students could be classified as problem gamblers. Hierarchical regression analysis showed that male gender, international student status, financial stress, negative affect and frequency of gambling on sports, horses/dogs, table games, casino gaming machines, internet casino games and bingo all significantly predicted problem gambling. Results from this study could inform gambling-education programs in universities as they indicate which groups are more vulnerable and specify which games pose more risk of problem gambling.

    Subjects with obstructive sleep apnea (OSA) have neurocognitive dysfunction. The aim of this study was to estimate the prevalence of symptoms and risk of OSA among university students and the association with academic performance. A cross-sectional study was conducted at Jordan University of Science and Technology. Students from faculties of engineering, medicine, nursing, pharmacy, and dentistry were asked to participate in this study. The Berlin Sleep Questionnaire was used to report symptoms and risk of OSA. Below average cumulative scores were considered poor academic performance. A total of 777 students (51% female; mean age, 20 years) completed the study questionnaire. According to the study definition, 42 students (5.4%) had high risk for OSA. Snoring was reported by 11% and daytime sleepiness and fatigue by 30%. Compared to female students, male students had more snoring (14.6 vs. 7.6%, p = 0.002) and higher risk for OSA (6.5 vs. 1.6%, p = 0.001). Both self-reported snoring and being at high risk for OSA were associated with poor academic performance (27.9 vs. 11.6% and 23.1 vs. 9.2%, respectively; p academic performance in students at high risk for OSA was 2.4 (CI 1.11-5.2, p = 0.027). Snoring and OSA were uncommon among university students. However, both were more common among male students and were associated with poor academic performance.

    The objective of this study is to identify levels of risk awareness for breast, lung and cervical cancer, in a UK student population. A sample of male (N=62) and female (N=58) university students, mean age 21.62 years completed a questionnaire identifying which risk factors they knew for each cancer. Analysis of variance was used to compare differences in risk awareness across gender and cancer types. Risk factor awareness was highest for lung cancer (0.78), mid-range for breast cancer (0.61) and lowest for cervical cancer (0.47). Women had greater risk factor awareness (0.67) than males (0.57) across all three cancers. There is also significant belief in mythic risk factors such as stress (from 14 to 40% across the three cancers). Previous research has demonstrated that risk factor awareness increases with educational status, yet even in a university student population, in which the majority of females would have been offered the HPV vaccination, risk factor awareness for cancers is variable. More health education is needed particularly around the risk factors for cervical cancer.

    2017-01-01

    The recent advent of genome and epigenome editing technologies has provided a new paradigm in which the landscape of the human genome and epigenome can be precisely manipulated in their native context. Genome and epigenome editing technologies can be applied to many aspects of aging research and offer the potential to develop novel therapeutics against age-related diseases. Here, we discuss the latest technological advances in the CRISPR-based genome and epigenome editing toolbox, and provide insight into how these synthetic biology tools could facilitate aging research by establishing in vitro cell and in vivo animal models to dissect genetic and epigenetic mechanisms underlying aging and age-related diseases. We discuss recent developments in the field with the aims to precisely modulate gene expression and dynamic epigenetic landscapes in a spatial and temporal manner in cellular and animal models, by complementing the CRISPR-based editing capability with conditional genetic manipulation tools including chemically inducible expression systems, optogenetics, logic gate genetic circuits, tissue-specific promoters, and the serotype-specific adeno-associated virus. We also discuss how the combined use of genome and epigenome editing tools permits investigators to uncover novel molecular pathways involved in the pathophysiology and etiology conferred by risk variants associated with aging and aging-related disease. A better understanding of the genetic and epigenetic regulatory mechanisms underlying human aging and age-related disease will significantly contribute to the developments of new therapeutic interventions for extending health span and life span, ultimately improving the quality of life in the elderly populations. © 2016 S.

    Full Text Available Abstract Background HIV testing and counseling (HTC with linkage to care after known infection are key components for HIV transmission prevention. This study was conducted to assess HTC uptake, HIV risk perception and linkage to care among Thai university students. Methods An outreach HTC program was conducted in a large public university in Thailand from January 2013 to December 2014. The program consisted of brief HIV knowledge assessment, free HTC, HIV risk assessment and education provided by the healthcare personnel. Students were categorized into low, moderate and high-risk groups according to the pre-defined HIV risk characteristics. Results One-thousand-eight-hundred-one students participated in the program, 494 (27 % underwent HTC. Independent characteristics associated with no HTC uptake included female sex (P < 0.001, lower HIV knowledge score (P < 0.001, younger age (P < 0.001 and students from non-health science faculties (P = 0.02. Among the 494 students undergoing HTC, 141 (29 % were categorized into moderate or high-risk group, of whom 45/141 (32 % had false perception of low HIV risk. Being heterosexual was independently associated with false perception of low HIV risk (P = 0.04. The rate of new HIV infection diagnosis was 4/494 (0.8 %. Of these 4 HIV-infected students, 3 (75 % were men who have sex with men and only 2 of the 4 students (50 % showed up for HIV continuity care. Conclusions An outreach HIV prevention program with HTC was feasible and beneficial in detecting HIV risk and infection among the university students. However, interventions to improve HTC uptake, HIV risk perception and linkage to care are needed.

    In this paper, we propose a pose editing and animation method for triangulated surfaces based on a user controlled partitioning of the model into deformable parts and rigid parts which are denoted handles. In our pose editing system, the user can sculpt a set of poses simply by transforming...... the handles for each pose. Using Laplacian editing, the deformable parts are deformed to match the handles. In our animation system the user can constrain one or several handles in order to define a new pose. New poses are interpolated from the examples poses, by solving a small non-linear optimization...... problem in order to obtain the interpolation weights. While the system can be used simply for building poses, it is also an animation system. The user can specify a path for a given constraint and the model is animated correspondingly....

    Full Text Available Background To assess the concept of children concerning their health and its risk factors, a group of primary and middle school students were asked to draw a few relevant pictures in order to deeply explore the comprehension of this key group. Methods In this cross-sectional study 1165 students, aged 7-15 years old, selected through random stratified sampling, were asked to draw a number of eight paintings, four paintings on health concepts, and the other four on health risk factors. The paintings were then assessed by two independent observers, and their themes and contents were abstracted and analyzed. Results The students drew a total of 2330 paintings, 1165 paintings on the concept of health, and 1165 paintings on health risk factors. The most and least expressed health concepts concerned “mental health” and “healthy diet” (73.3% and 4.8%, respectively. Considering health risk factors, “unhealthy diet” and the two concepts of “environmental hazards” and “neglected personal hygiene” had the most (95% and least (1.4% each frequencies. Students in public schools, primary level and girls drew more pictures about health concept or/and its risk factors (PConclusion Although students had a broad view about health and its risk factors, generally little attention had been paid to some of the main aspects such as physical activity, healthy diet, mental and oral health, and environmental hazards. In addition, it seems that parents’ educational level, as one of the main socio-economic factors, did not have any significant impact on their concepts.

    Full Text Available Background. Medications are not exempt from adverse drug reactions (ADR and how the physician perceives the risk of prescription drugs could influence their availability to report ADR and their prescription behavior. Methods. We assess the perception of risk and the perception of ADR associated with COX2-Inbitors, paracetamol, NSAIDs, and morphine in medical students and residents of northeast of Mexico. Results. The analgesic with the highest risk perception in both group of students was morphine, while the drug with the least risk perceived was paracetamol. Addiction and gastrointestinal bleeding were the ADR with the highest score for morphine and NSAIDs respectively. Discussion. Our findings show that medical students give higher risk scores than residents toward risk due to analgesics. Continuing training and informing physicians about ADRs is necessary since the lack of training is known to induce inadequate use of drugs.

  5. The expression of apoB mRNA editing factors is not the sole determinant for the induction of editing in differentiating Caco-2 cells

    International Nuclear Information System (INIS)

    Galloway, Chad A.; Smith, Harold C.

    2010-01-01

    Apolipoprotein B mRNA is edited at cytidine 6666 in the enterocytes lining the small intestine of all mammals; converting a CAA codon to a UAA stop codon. The conversion is ∼80% efficient in this tissue and leads to the expression of the truncated protein, ApoB48, essential for secretion of dietary lipid as chylomicrons. Caco-2 cell raft cultures have been used as an in vitro model for the induction of editing activity during human small intestinal cell differentiation. This induction of apoB mRNA editing has been ascribed to the expression of APOBEC-1. In agreement our data demonstrated differentiation-dependent induction of expression of the editing enzyme APOBEC-1 and in addition we show alternative splicing of the essential auxiliary factor ACF. However, transfection of these editing factors in undifferentiated proliferating Caco-2 cells was not sufficient to induce robust apoB mRNA editing activity. Only differentiation of Caco-2 cells could induce more physiological like levels of apoB mRNA editing. The data suggested that additional regulatory mechanism(s) were induced by differentiation that controlled the functional activity of editing factors.

    Full Text Available Genome editing opens new and unique opportunities for researchers to enhance crop production. Until 2013, the zinc finger nucleases (ZFNs and transcription activator-like effector nucleases (TALENs were the key tools used for genome editing applications. The advent of RNA-guided engineered nucleases - the type II clustered regularly interspaced short palindromic repeat (CRISPR/Cas9 (CRISPR-associated system from Streptococcus pyogenes holds great potential since it is simple, effective and more versatile than ZFNs and TALENs. CRISPR/Cas9 system has already been successfully employed in several crop plants. Use of these techniques is in its infant stage in sugarcane. Jung and Altpeter (2016 have reported TALEN mediated approach for the first time to reduce lignin content in sugarcane to make it amenable for biofuel production. This is so far the only report describing genome editing in sugarcane. Large genome size, polyploidy, low transformation efficiency, transgene silencing and lack of high throughput screening techniques are certainly great challenges for genome editing in sugarcane which would be discussed in detail in this review.

  9. Edit propagation using geometric relationship functions

    Guerrero, Paul; Jeschke, Stefan; Wimmer, Michael; Wonka, Peter

    2014-01-01

    We propose a method for propagating edit operations in 2D vector graphics, based on geometric relationship functions. These functions quantify the geometric relationship of a point to a polygon, such as the distance to the boundary or the direction to the closest corner vertex. The level sets of the relationship functions describe points with the same relationship to a polygon. For a given query point, we first determine a set of relationships to local features, construct all level sets for these relationships, and accumulate them. The maxima of the resulting distribution are points with similar geometric relationships. We show extensions to handle mirror symmetries, and discuss the use of relationship functions as local coordinate systems. Our method can be applied, for example, to interactive floorplan editing, and it is especially useful for large layouts, where individual edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds of objects by propagating relatively few edit operations. © 2014 ACM 0730-0301/2014/03- ART15 $15.00.

    Full Text Available Research supports the implementation of mentoring programs as potentially successful approaches to meeting the needs of at-risk students. This study examined a mentoring program entitled: LISTEN (Linking Individual Students To Educational Needs. The LISTEN mentoring program was a district-sponsored, school-based program in which at-risk, middle school students were identified by the school system and mentors were recruited specifically to assist these students with school performance or related issues. Mentors, in this study, were classroom teachers, school counselors, administrators, custodians, librarians, teaching assistants, retired teachers, and cafeteria employees. Archival data from the 2003–04 and 2004–05 academic years were analyzed. A statistically significant difference was found for all three of the study’s criterion variables (GPAs, discipline referrals, and attendance records between those measured in the 2003–04 academic year (pre-intervention and those measured in the 2004–05 academic year (post-intervention. Forty-nine of the fifty-four LISTEN participants experienced academic achievement gains in all three areas of the study.

    In 1995, a survey was conducted among students attending 69 Seventh-day Adventist (SDA) high schools within the United States and Canada. The survey assessed the extent that these students practiced sexual and drug-use behaviors which place them at risk for contracting or transmitting the human immunodeficiency virus (HIV). A total of 1,748 respondents enrolled in grades 9 through 12 completed questionnaires similar to the instrument used in the 1993 Youth Risk Behavior Survey (YRBS). Data were collected and compared to results from the 1993 YRBS. Students who attended SDA parochial schools reported lower rates of sexual intercourse compared to YRBS school counterparts (16.3% vs. 53.1%) and lower rates of all substances measured. Furthermore, respondents were more likely to engage in substance use and sexual intercourse if they had at least one parent who used tobacco, alcohol, or marijuana, as reported by the students.

  13. IMRT fluence map editing to control hot and cold spots

    2005-01-01

    Manually editing intensity-modulated radiation therapy (IMRT) fluence maps effectively controls hot and cold spots that the IMRT optimization cannot control. Many times, re-optimizing does not reduce the hot spots or increase the cold spots. In fact, re-optimizing only places the hot and cold spots in different locations. Fluence-map editing provides manual control of dose delivery and provides the best treatment plan possible. Several IMRT treatments were planned using the Varian Eclipse planning system. We compare the effects on dose distributions between fluence-map editing and re-optimization, discuss techniques for fluence-map editing, and analyze differences between fluence editing on one beam vs. multiple beams. When editing a beam's fluence map, it is essential to choose a beam that least affects dose to the tumor and critical structures. Editing fluence maps gives an advantage in treatment planning and provides controlled delivery of IMRT dose

    We tested a model consistent with the notion that perceived burdensomeness and thwarted belongingness mediate the association between future orientation and suicide risk (viz., depressive symptoms and suicide ideation) in college students. The sample was comprised of 195 Hungarian college students. Results indicated that the negative associations found between future orientation and suicide risk outcomes were accounted for by both perceived burdensomeness and thwarted belongingness. The present findings highlight the importance of studying positive future cognitions in suicide risk and provide support for perceived burdensomeness and thwarted belongingness as potential proximal mechanisms associated with heighted suicide risk in adults.

    2010-01-01

    "The Explanatory Supplement to the Astronomical Almanac" (hereafter "The Explanatory Supplement") is a comprehensive reference book on the topic of positional astronomy, covering the theories and algorithms used to produce "The Astronomical Almanac" (AsA), an annual publication produced jointly by the Nautical Almanac Office of the US Naval Observatory (USNO) and Her Majesty's Nautical Almanac Office (HMNAO) of the UK Hydrographic Office. The first edition of The Explanatory Supplement appeared in 1961 and was reprinted with amendments during the 1970s. The second edition was printed in 1992 and reprinted until 2006. Since the second edition, several changes have taken place in positional astronomy regarding reference systems and internationally accepted models, data sets, and computational methods; these have been incorporated into the AsA. Additionally, the data presented in the AsA have been modified over the years, with new tables being added and some being discontinued. Given these changes, a new edition of The Explanatory Supplement is appropriate. The third edition has been in development for the last few years and will be available in 2010. The book is organized similarly to the second (1991) edition, with each chapter written by subject matter experts. Authors from USNO and HMNAO contributed to the majority of the book, but there are authors from Jet Propulsion Laboratory, Technical University of Dresden, National Geospatial-Intelligence Agency, University of Texas Austin, and University of Virginia. This paper will discuss this latest edition of the Explanatory Supplement.

    The association between non-nutritive sweeteners and obesity is controversial. To determine whether the consumption of non-nutritive sweeteners is related to higher risk for overweight or obesity among university students in Chile, Panama, Guatemala and Peru. A total of 1,224 (472 from Chile, 300 from Panama, 248 from Guatemala and 204 from Peru) male and female university students aged between 18 and 26 years participated in the study. Each student reported their food intake (frequency of weekly consumption) in a survey that contained photos of foods containing non-nutritive sweeteners adapted for each country. Anthropometry was also measured. More than 80% of students consumed at least one product containing non-nutritive sweeteners. Females who ate acesulfame potassium and sucralose had a lower risk of overweight or obesity with an odds ratio (OR) of 0.5 (confidence intervals (CI) = 0.3-0.9; p = 0.003) and OR = 0.4 (IC = 0.2-0.8; p = 0.01), respectively. In this sample of Latinamerican university students, consumption of non-nutritive sweeteners was associated with lower risk of overweight only in females.

    This research study examined the behavioral lifestyle patterns and health status of at-risk Latino college students for future diabetes onset in relation to their age, gender, and acculturation status. Participants were 156 Latino (34% male and 66% female) university students who had a first and/or second degree relative afflicted with diabetes. Findings indicated that Latino students exhibit similar lifestyle patterns in terms of dietary intake, physical activity, and drinking and smoking behaviors observed in the general and college population that have been linked to obesity-a particularly problematic risk factor among those who already have a genetic predisposition for diabetes. The reported findings are of importance for the development of culturally-relevant treatment interventions targeting young Latinos in college.

  7. Measuring the Outcome of At-Risk Students on Biology Standardized Tests When Using Different Instructional Strategies

    Science.gov (United States)

    Burns, Dana

    Over the last two decades, online education has become a popular concept in universities as well as K-12 education. This generation of students has grown up using technology and has shown interest in incorporating technology into their learning. The idea of using technology in the classroom to enhance student learning and create higher achievement has become necessary for administrators, teachers, and policymakers. Although online education is a popular topic, there has been minimal research on the effectiveness of online and blended learning strategies compared to the student learning in a traditional K-12 classroom setting. The purpose of this study was to investigate differences in standardized test scores from the Biology End of Course exam when at-risk students completed the course using three different educational models: online format, blended learning, and traditional face-to-face learning. Data was collected from over 1,000 students over a five year time period. Correlation analyzed data from standardized tests scores of eighth grade students was used to define students as "at-risk" for failing high school courses. The results indicated a high correlation between eighth grade standardized test scores and Biology End of Course exam scores. These students were deemed "at-risk" for failing high school courses. Standardized test scores were measured for the at-risk students when those students completed Biology in the different models of learning. Results indicated significant differences existed among the learning models. Students had the highest test scores when completing Biology in the traditional face-to-face model. Further evaluation of subgroup populations indicated statistical differences in learning models for African-American populations, female students, and for male students.

  10. A Subdivision-Based Representation for Vector Image Editing.

    Science.gov (United States)

    Liao, Zicheng; Hoppe, Hugues; Forsyth, David; Yu, Yizhou

    2012-11-01

    Vector graphics has been employed in a wide variety of applications due to its scalability and editability. Editability is a high priority for artists and designers who wish to produce vector-based graphical content with user interaction. In this paper, we introduce a new vector image representation based on piecewise smooth subdivision surfaces, which is a simple, unified and flexible framework that supports a variety of operations, including shape editing, color editing, image stylization, and vector image processing. These operations effectively create novel vector graphics by reusing and altering existing image vectorization results. Because image vectorization yields an abstraction of the original raster image, controlling the level of detail of this abstraction is highly desirable. To this end, we design a feature-oriented vector image pyramid that offers multiple levels of abstraction simultaneously. Our new vector image representation can be rasterized efficiently using GPU-accelerated subdivision. Experiments indicate that our vector image representation achieves high visual quality and better supports editing operations than existing representations.

    This study determines the differences in health risk behavior, knowledge, and health benefit beliefs between health science and non-health science university students in 17 low and middle income countries. Anonymous questionnaire data were collected in a cross-sectional survey of 13,042 undergraduate university students (4,981 health science and 8,061 non-health science students) from 17 universities in 17 countries across Asia, Africa, and the Americas. Results indicate that overall, health science students had the same mean number of health risk behaviors as non-health science university students. Regarding addictive risk behavior, fewer health science students used tobacco, were binge drinkers, or gambled once a week or more. Health science students also had a greater awareness of health behavior risks (5.5) than non-health science students (4.6). Linear regression analysis found a strong association with poor or weak health benefit beliefs and the health risk behavior index. There was no association between risk awareness and health risk behavior among health science students and an inverse association among non-health science students. © 2015 Wiley Publishing Asia Pty Ltd.

    Studies using traditional screening instruments tend to report a lower prevalence of eating disorders (EDs) in men than is observed in women. It is therefore unclear whether such instruments are valid for the assessment of ED in males. Lack of a formal diagnostic definition of muscle dysmorphia syndrome (MD) makes it difficult to identify men at risk. The study aimed to assess the prevalence of ED and MD in male university students of Buenos Aires. A cross-sectional, two-stage, representative survey was of 472 male students from six different schools in Buenos Aires, mostly aged between 18 and 28 years. The first stage involved administration of self-report questionnaires (Eating Attitude Test-26; scores ≥15 indicate "at risk" status). In Stage 2 students at risk of developing EDs were evaluated with a clinical interview, the Eating Disorder Examination (EDE; 12th edition). Two control students were interviewed for every at risk student. The prevalence of EDs among university male students was 1.9% (n = 9). All participants with an ED presented with illness classified as eating disorder not otherwise specified (EDNOS). Using the Drive for Muscularity Scale (DMS) with a 52-point threshold we identified possible MD in 6.99% (n = 33) of the sample. The prevalence of ED detected in this study is comparable with previous findings in male populations, and below that observed in female populations. However, the prevalence of possible cases of MD resembles the total rate of EDs in women. Characteristics associated with EDs and MD in men are also discussed. © 2015 Wiley Periodicals, Inc.

    The adolescence period of life comes along with changes and challenges in terms of physical and cognitive development. In this hectic period, many adolescents may suffer more from various risk factors such as low socioeconomic status, substance abuse, sexual abuse and teenage pregnancy. Findings indicate that such disadvantaged backgrounds of Malaysian adolescent students lead to failure or underachievement in their academic performance. This narrative review scrutinises how some of these students are able to demonstrate academic resilience, which is satisfactory performance in cognitive or academic tasks in spite of their disadvantaged backgrounds. The review stresses the need for developing a caregiving relationship model for at-risk adolescent students in Malaysia. Such a model would allow educators to meet the students' needs for enhancing thinking skills, counteracting risk factors and demonstrating academic resilience. PMID:25663734

  16. Global Bathymetry: Machine Learning for Data Editing

    The accuracy of global bathymetry depends primarily on the coverage and accuracy of the sounding data and secondarily on the depth predicted from gravity. A main focus of our research is to add newly-available data to the global compilation. Most data sources have 1-12% of erroneous soundings caused by a wide array of blunders and measurement errors. Over the years we have hand-edited this data using undergraduate employees at UCSD (440 million soundings at 500 m resolution). We are developing a machine learning approach to refine the flagging of the older soundings and provide automated editing of newly-acquired soundings. The approach has three main steps: 1) Combine the sounding data with additional information that may inform the machine learning algorithm. The additional parameters include: depth predicted from gravity; distance to the nearest sounding from other cruises; seafloor age; spreading rate; sediment thickness; and vertical gravity gradient. 2) Use available edit decisions as training data sets for a boosted tree algorithm with a binary logistic objective function and L2 regularization. Initial results with poor quality single beam soundings show that the automated algorithm matches the hand-edited data 89% of the time. The results show that most of the information for detecting outliers comes from predicted depth with secondary contributions from distance to the nearest sounding and longitude. A similar analysis using very high quality multibeam data shows that the automated algorithm matches the hand-edited data 93% of the time. Again, most of the information for detecting outliers comes from predicted depth secondary contributions from distance to the nearest sounding and longitude. 3) The third step in the process is to use the machine learning parameters, derived from the training data, to edit 12 million newly acquired single beam sounding data provided by the National Geospatial-Intelligence Agency. The output of the learning algorithm will be

    Understanding behavioural risk factors of cardiovascular disease (CVD) is of great importance for CVD prevention and control. The aim of the study was to investigate the prevalence, risk awareness and health beliefs of behavioural risk factors of cardiovascular disease among university students in Association of Southeast Asian Nations (ASEAN) member states. In a cross-sectional survey 8806 (37.5% male and 62.5% female) university students (Mean age 20.6, SD = 2.0) from nine ASEAN countries responded to an anonymous questionnaire. Results indicate that across all nine countries, among men and women, 27.5% and 16.9%, respectively, were overweight or obese, 39.0% and 53.0% engaged in low physical activity, 6.9% and 2.5% were current tobacco users, 10.1% and 4.2% had engaged in binge drinking in the past month and 62.7% and 58.2%, respectively, did not avoid eating fat and cholesterol. After adjusting for socio-demographic factors, health status and health benefits, poor risk awareness was associated with tobacco use and binge drinking, and after adjusting for socio-demographic factors, health status and risk awareness, poorer health benefits beliefs predicted overweight, low physical activity, tobacco use, binge drinking and non-avoidance of fat and cholesterol. The study found a high prevalence of behavioural risk factors of CVD. Results may inform health promotion strategies among university students in ASEAN.

  19. Genome Editing: A New Approach to Human Therapeutics.

    2016-01-01

    The ability to manipulate the genome with precise spatial and nucleotide resolution (genome editing) has been a powerful research tool. In the past decade, the tools and expertise for using genome editing in human somatic cells and pluripotent cells have increased to such an extent that the approach is now being developed widely as a strategy to treat human disease. The fundamental process depends on creating a site-specific DNA double-strand break (DSB) in the genome and then allowing the cell's endogenous DSB repair machinery to fix the break such that precise nucleotide changes are made to the DNA sequence. With the development and discovery of several different nuclease platforms and increasing knowledge of the parameters affecting different genome editing outcomes, genome editing frequencies now reach therapeutic relevance for a wide variety of diseases. Moreover, there is a series of complementary approaches to assessing the safety and toxicity of any genome editing process, irrespective of the underlying nuclease used. Finally, the development of genome editing has raised the issue of whether it should be used to engineer the human germline. Although such an approach could clearly prevent the birth of people with devastating and destructive genetic diseases, questions remain about whether human society is morally responsible enough to use this tool.

  20. Gender Differences in Risk Aversion Among Chinese University Students.

    2015-12-01

    This paper examines gender differences in risk aversion among Chinese university students. Chinese females are proposed to be more risk averse and require a higher risk premium when faced with a gamble option in the gain-domain frame as compared to Chinese males. Two groups of 100 participants each (male = 100 and female = 100 in total) were recruited to fill up questionnaires that included items relating to objective probability lotteries. Within each group, it was found that Chinese males and females did not differ in their risk aversion. However, results show that Chinese males tend to react more readily to rising risk premium by taking up options with higher expected values when compared to Chinese females. Current findings will have useful implications to marketers (particularly, promoters of gambling products) and problem gambling counselors.

    The aim of this study was to assess religiosity and health risk behaviours among university students from 26 low, middle and high income countries. Using anonymous questionnaires, data were collected from 20,222 undergraduate university students (mean age 20.8, SD = 2. 8) from 27 universities in 26 countries across Asia, Africa and the Americas. Among all students, 41.1 % engaged at least once a week in organized religious activity, 35.8 % practised a non-organized religious activity daily or more than once daily, and more or less two-thirds of the students agreed to the three different statements on intrinsic of subjective religiosity. In multivariate logistic regression analysis, higher reported involvement in organized religious activity was associated with addictive, injury, sexual and oral health risk behaviour, while lower reported involvement in organized religious activity was associated with physical inactivity and oral health risk behaviour. Lower reported involvement in non-organized religious activity was associated with addictive, nutrition risk, injury, sexual and oral health risk behaviour, while higher reported involvement in non-organized religious activity was associated with physical inactivity. Finally, lower reported intrinsic religiosity was associated with addictive and sexual risk behaviour, while higher reported intrinsic religiosity was associated with nutrition risk behaviour, physical inactivity and oral health risk behaviour.

    2015-12-12

    RNA editing usually affects only a fraction of expressed transcripts and there is a vast amount of variation in editing levels of ADAR (adenosine deaminase, RNA-specific) targets. Here we explore natural genetic variation affecting editing levels of particular sites in 81 natural strains of Drosophila melanogaster. The analysis of associations between editing levels and single-nucleotide polymorphisms allows us to map putative cis-regulatory regions affecting editing of 16 A-to-I editing sites (cis-RNA editing quantitative trait loci or cis-edQTLs, P < 10(-8)). The observed changes in editing levels are validated by independent molecular technique. All identified regulatory variants are located in close proximity of modulated editing sites. Moreover, colocalized editing sites are often regulated by same loci. Similar to expression and splicing QTL studies, the characterization of edQTLs will greatly expand our understanding of cis-regulatory evolution of gene expression.

    To assess non-medical university students' knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. A cross-sectional survey was conducted among non-medical students of a private Midwestern university in the United States in May 2012. Questionnaire assessed demographic information and contained 21 previously validated questions regarding knowledge and perceived risk of developing oral cavity and oropharyngeal cancer. Knowledge scale was categorized into low and high. Risk level was estimated based on smoking, drinking, and sexual habits. Bivariate associations between continuous and categorical variables were assessed using Pearson correlation and Chi-square tests, respectively. The response rate was 87% (100 out of 115 students approached). Eighty-one percent (81%) had low oral cavity and oropharyngeal cancer knowledge; and only 2% perceived that their oral cavity and oropharyngeal cancer risk was high. Risk perception was negatively correlated with age at sexual debut, r (64) = -0.26, p = 0.037; one-way ANOVA showed a marginally significant association between risk perception and number of sexual partners, F(4, 60) = 2.48, p = 0.05. There was no significant association between knowledge and perception of risk; however, oral cavity and oropharyngeal cancer knowledge was significantly associated with frequency of prevention of STDs (p risk perception is low among this student population. Since oral cavity and oropharyngeal cancer incidence is increasingly shifting towards younger adults, interventions must be tailored to this group in order to improve prevention and control.

    RNA editing is a post-transcriptional process that modifies RNA molecules leading to transcript sequences that differ from their template DNA. A-to-I editing was found to be widely distributed in nuclear transcripts of metazoa, but was detected in fungi only recently in a study of the filamentous ascomycete Fusarium graminearum that revealed extensive A-to-I editing of mRNAs in sexual structures (fruiting bodies). Here, we searched for putative RNA editing events in RNA-seq data from Sordaria macrospora and Pyronema confluens, two distantly related filamentous ascomycetes, and in data from the Taphrinomycete Schizosaccharomyces pombe. Like F. graminearum, S. macrospora is a member of the Sordariomycetes, whereas P. confluens belongs to the early-diverging group of Pezizomycetes. We found extensive A-to-I editing in RNA-seq data from sexual mycelium from both filamentous ascomycetes, but not in vegetative structures. A-to-I editing was not detected in different stages of meiosis of S. pombe. A comparison of A-to-I editing in S. macrospora with F. graminearum and P. confluens, respectively, revealed little conservation of individual editing sites. An analysis of RNA-seq data from two sterile developmental mutants of S. macrospora showed that A-to-I editing is strongly reduced in these strains. Sequencing of cDNA fragments containing more than one editing site from P. confluens showed that at the beginning of sexual development, transcripts were incompletely edited or unedited, whereas in later stages transcripts were more extensively edited. Taken together, these data suggest that A-to-I RNA editing is an evolutionary conserved feature during fruiting body development in filamentous ascomycetes. © The Author(s) 2017.

    Forward planning and preventative measures before travelling can significantly reduce the risk of many vaccine preventable travel-related infectious diseases. Higher education students may be at an increased risk of importing infectious disease as many undertake multiple visits to regions with higher infectious disease endemicity. Little is known about the health behaviours of domestic or international university students, particularly students from low resource countries who travel to high-resource countries for education. This study aimed to assess travel-associated health risks and preventative behaviours in a sample of both domestic and international university students in Australia. In 2010, a 28 item self-administered online survey was distributed to students enrolled at the University of New South Wales, Sydney, Australia. Multiple methods of distributing links to the online survey were utilised. The survey examined the international travel history, travel intentions, infection control behaviours and self-reported vaccination history. A total of 1663 respondents completed the online survey, 22.1% were international students and 83.9% were enrolled at an undergraduate level. Half had travelled internationally in the previous 12 months, with 69% of those travelling only once during that time with no difference in travel from Australia between domestic and international students (p = 0.8). Uptake of pre-travel health advice was low overall with 68% of respondents reporting they had not sought any advice from a health professional prior to their last international trip. Domestic students were more likely to report uptake of a range of preventative travel health measures compared to international students, including diarrhoeal medication, insect repellent, food avoidance and condoms (P students reported low risk perception of travel threats and a low corresponding concern for these threats. Our study highlights the need to educate students about the risk

    Transcripts have been found to be site selectively edited from adenosine-to-inosine (A-to-I) in the mammalian brain, mostly in genes involved in neurotransmission. While A-to-I editing occurs at double-stranded structures, other structural requirements are largely unknown. We have investigated...... shown to be important for A-to-I editing. We demonstrate that the element also can induce editing in related but normally not edited RNA sequences. In human, thousands of genes are edited in duplexes formed by inverted repeats in non-coding regions. It is likely that numerous such duplexes can induce...... the requirements for editing at the I/M site in the Gabra-3 transcript of the GABA(A) receptor. We identify an evolutionarily conserved intronic duplex, 150 nt downstream of the exonic hairpin where the I/M site resides, which is required for its editing. This is the first time a distant RNA structure has been...

    2013-09-30

    Capturing carbon dioxide (CO2) and injecting it into deep underground formations for storage (carbon capture and underground storage, or CCUS) is one way of reducing anthropogenic CO2 emissions. Gas or aqueous-phase leakage may occur due to transport via faults and fractures, through faulty well bores, or through leaky confining materials. Contaminants of concern include aqueous salts and dissolved solids, gaseous or aqueous-phase organic contaminants, and acidic gas or aqueous-phase fluids that can liberate metals from aquifer minerals. Understanding the mechanisms and parameters that can contribute to leakage of the CO2 and the ultimate impact on shallow water aquifers that overlie injection formations is an important step in evaluating the efficacy and risks associated with long-term CO2 storage. Three students were supported on the grant Training Graduate and Undergraduate Students in Simulation and Risk Assessment for Carbon Sequestration. These three students each examined a different aspect of simulation and risk assessment related to carbon dioxide sequestration and the potential impacts of CO2 leakage. Two performed numerical simulation studies, one to assess leakage rates as a function of fault and deep reservoir parameters and one to develop a method for quantitative risk assessment in the event of a CO2 leak and subsequent changes in groundwater chemistry. A third student performed an experimental evaluation of the potential for metal release from sandstone aquifers under simulated leakage conditions. This study has resulted in two student first-authored published papers {Siirila, 2012 #560}{Kirsch, 2014 #770} and one currently in preparation {Menke, In prep. #809}.

  16. The agents of natural genome editing.

    Witzany, Guenther

    2011-06-01

    The DNA serves as a stable information storage medium and every protein which is needed by the cell is produced from this blueprint via an RNA intermediate code. More recently it was found that an abundance of various RNA elements cooperate in a variety of steps and substeps as regulatory and catalytic units with multiple competencies to act on RNA transcripts. Natural genome editing on one side is the competent agent-driven generation and integration of meaningful DNA nucleotide sequences into pre-existing genomic content arrangements, and the ability to (re-)combine and (re-)regulate them according to context-dependent (i.e. adaptational) purposes of the host organism. Natural genome editing on the other side designates the integration of all RNA activities acting on RNA transcripts without altering DNA-encoded genes. If we take the genetic code seriously as a natural code, there must be agents that are competent to act on this code because no natural code codes itself as no natural language speaks itself. As code editing agents, viral and subviral agents have been suggested because there are several indicators that demonstrate viruses competent in both RNA and DNA natural genome editing.

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

    Full Text Available Aim. The aim of this study is to detect the prevalence of substance use among tenth-grade students; their thoughts, attitudes, behaviors, and tendencies towards substance use; and risk factors of substance use in tenth-grade students in general. Methods. This study is descriptive and cross-sectional conducted between April and May 2016. Research population consists of tenth-grade students in 2015-2016 school year in the city of Ordu. Since the study involved all tenth-grade students, no sampling was done. Questions on substance use were prepared by Ordu Public Health Directorate and the authors by making use of European School Survey Project on Alcohol and Other Drugs (ESPAD study questions, AMATEM’s “Drugs and Addiction Youth Survey” study conducted on May 1996, and scientific studies conducted previously on similar subjects. Results. 9825 tenth-grade students in 88 schools from 19 counties in the city of Ordu were included in the study. 8714 of the students participated in the survey. Being male, being over the age of 15, mother and father being separated, living with relatives, being in low income, negative feelings about school, perception of being unsuccessful in school, failing a year, absenteeism, and not being content with life are the risk factors for substance use. Conclusions. The tendency of illegal substance use becoming more and more prevalent especially among youth requires the development of new treatment strategies.

    Adenosine-to-inosine (A-to-I) editing modifies RNA transcripts from their genomic blueprint. A prerequisite for this process is a double-stranded RNA (dsRNA) structure. Such dsRNAs are formed as part of the microRNA (miRNA) maturation process, and it is therefore expected that miRNAs are affected by A-to-I editing. Editing of miRNAs has the potential to add another layer of complexity to gene regulation pathways, especially if editing occurs within the miRNA–mRNA recognition site. Thus, it is of interest to study the extent of this phenomenon. Current reports in the literature disagree on its extent; while some reports claim that it may be widespread, others deem the reported events as rare. Utilizing a next-generation sequencing (NGS) approach supplemented by an extensive bioinformatic analysis, we were able to systematically identify A-to-I editing events in mature miRNAs derived from human brain tissues. Our algorithm successfully identified many of the known editing sites in mature miRNAs and revealed 17 novel human sites, 12 of which are in the recognition sites of the miRNAs. We confirmed most of the editing events using in vitro ADAR overexpression assays. The editing efficiency of most sites identified is very low. Similar results are obtained for publicly available data sets of mouse brain-regions tissues. Thus, we find that A-to-I editing does alter several miRNAs, but it is not widespread. PMID:22499667

    Direct delivery of purified Cas9 protein with guide RNA into plant cells, as opposed to plasmid-mediated delivery, displays high efficiency and reduced off-target effects. Following regeneration from edited cells, the ensuing plant is also likely to bypass genetically modified organism (GMO) legislation as the genome editing complex is degraded in the recipient cells.

    2011-01-01

    This is the second edition of the book “Thermodynamics of Fluids under Flow,” which was published in 2000 and has now been corrected, expanded and updated. This is a companion book to our other title Extended irreversible thermodynamics (D. Jou, J. Casas-Vázquez and G. Lebon, Springer, 4th edition 2010), and of the textbook Understanding non-equilibrium thermodynamics (G. Lebon, D. Jou and J. Casas-Vázquez, Springer, 2008. The present book is more specialized than its counterpart, as it focuses its attention on the non-equilibrium thermodynamics of flowing fluids, incorporating non-trivial thermodynamic contributions of the flow, going beyond local equilibrium theories, i.e., including the effects of internal variables and of external forcing due to the flow. Whereas the book's first edition was much more focused on polymer solutions, with brief glimpses into ideal and real gases, the present edition covers a much wider variety of systems, such as: diluted and concentrated polymer solutions, polymer ble...

    Aim To evaluate the risk factors of needle stick injuries (NSIs) sustained by undergraduate dental students and nurse students at the King's College London (KCL) Dental Institute. Materials and methods A retrospective study evaluated the incident reports relating to NSIs reported over a period of 2 years. Factors including the dental department, study year, and when the injury took place during administration of local anaesthesia (LA) and recapping conventional syringe or clearing work surface or during disposal. Results This report showed that students are at the highest risk of NSIs at the fourth year of their 5-year BDS course. About one-third of injuries were reported among this group of students followed by year 5 students (25%). Oral surgery clinics were the major source of incident reporting when compared with other specialised dental clinics within the institute. The left hands of the students were the most frequently affected by such injuries and then the right hands of student dental nurses. The attempt of needle recapping of conventional syringes was the least reported mechanism of injuries and constituted only 15% of the total injuries and mainly occurred in third year students. The most frequent injuries among student nurses were during disposal of the needle. Conclusion Less NSIs occur when using safety syringes. A non-recapping policy with immediate disposal of either the conventional or safety syringe systems after injection would prevent all clearance-related NSIs sustained by nurses. To avoid NSIs, education plays a vital role particularly with effective implementation of the change to safety syringes with appropriate training. PMID:22741025

    To explore the association between emotional intelligence (EI) and risky health behaviors in nursing students at the University of Oviedo (Spain). This cross-sectional study of 275 students used a validated questionnaire to measure EI level, nine risky behaviors (smoking, excessive alcohol consumption, illicit drug use, unhealthy diet, being overweight, sedentarism, risky sun exposure, occupational risk, and unsafe sex), and other factors that may influence EI. Students with the highest EI score had a lower probability of drinking too much alcohol (odds ratio [OR], 0.31; 95% confidence interval [CI] [0.19, 0.67]), eating too few fruits and vegetables (OR, 0.60; 95% CI [0.34, 0.99]), and having unsafe sex (OR, 0.10; 95% CI [0.01, 0.74]). A dose-response effect was found for those three behaviors (p for trend excessive alcohol consumption, unhealthy diet, and unsafe sex. Training nursing students about EI could improve health behaviors, and thus the role of nurses as health promoters. Copyright 2015, SLACK Incorporated.

  10. Nanoparticles for Site Specific Genome Editing

    Science.gov (United States)

    McNeer, Nicole Ali

    Triplex-forming peptide nucleic acids (PNAs) can be used to coordinate the recombination of short 50-60 by "donor DNA" fragments into genomic DNA, resulting in site-specific correction of genetic mutations or the introduction of advantageous genetic modifications. Site-specific gene editing in hematopoietic stem and progenitor cells (HSPCs) could result in treatment or cure of inherited disorders of the blood such as beta-thalassemia. Gene editing in HSPCs and differentiated T cells could help combat HIV/AIDs by modifying receptors, such as CCR5, necessary for R5-tropic HIV entry. However, translation of genome modification technologies to clinical practice is limited by challenges in intracellular delivery, especially in difficult-to-transfect hematolymphoid cells. In vivo gene editing could also provide novel treatment for systemic monogenic disorders such as cystic fibrosis, an autosomal recessive disorder caused by mutations in the cystic fibrosis transmembrane receptor. Here, we have engineered biodegradable nanoparticles to deliver oligonucleotides for site-specific genome editing of disease-relevant genes in human cells, with high efficiency, low toxicity, and editing of clinically relevant cell types. We designed nanoparticles to edit the human beta-globin and CCR5 genes in hematopoietic cells. We show that poly(lactic-co-glycolic acid) (PLGA) nanoparticles can delivery PNA and donor DNA for site-specific gene modification in human hematopoietic cells in vitro and in vivo in NOD-scid IL2rgammanull mice. Nanoparticles delivered by tail vein localized to hematopoietic compartments in the spleen and bone marrow of humanized mice, resulting in modification of the beta-globin and CCR5 genes. Modification frequencies ranged from 0.005 to 20% of cells depending on the organ and cell type, without detectable toxicity. This project developed highly versatile methods for delivery of therapeutics to hematolymphoid cells and hematopoietic stem cells, and will help to

    Full Text Available 1–3 year students attending medical and preventive faculty of a medical university were our research object. Our research had many stages, and at the first one our goal was to examine and to assess basic behavioral risks for reproductive health of students attending medical and preventive faculty of a medical university. We conducted a sociological examination via questioning. 428 students were questioned as per materials collecting program which included 74 parameters; they accounted for 91.6 % out of the overall official number of students, 45.0 % male students and 40.0 % female students combined work and studies. We detected that, as per questioning results, the specific weight of students who took care of their health amounted to 79.2 % boys and 95.2 % girls. However, the students tended to have bad habits, i.e. constant alcohol intake or smoking. And although information on diseases prevention and on how to pursue healthy lifestyle was perfectly available to them, students didn't try to use it and preserve their health. All the respondents said they were against abortion. Girls were likely to adopt a complex approach when choosing a contraceptive, they resorted to hormonal agents, and, with their partners' consent, to condoms. But they often took hormonal agents without any consultations with a gynecologist or an endocrinologist. Contraceptives were rather rarely applied, and students appeared to have no knowledge on risk factors causing reproductive health deterioration. They also tended to be negligent and too self-confident when it came to reproductive health protection. A risk of abortions was very high for girls who didn't use contraceptives, and also all students ran rather high risk of catching sexual diseases. Sexual education is needed to correct contraceptive behavior; medical workers are a main source of information on reproductive health of young people in 7–10 % cases only. We need to create interactive educational programs

    Although there are a large number of studies focused on binge drinking and traffic risk behaviors (TRB), little is known regarding low levels of alcohol consumption and its association to TRB. The aim of this cross-sectional study is to examine the association of low to moderate alcohol intake pattern and TRB in college students in Brazil. 7037 students from a National representative sample were selected under rigorous inclusion criteria. All study participants voluntarily fulfilled a structured, anonymous, and self-questionnaire regarding alcohol and drug use, social-demographic data, and TRB. Alcohol was assessed according to the average number of alcoholic units consumed on standard occasions over the past 12 months. The associations between alcohol intake and TRB were summarized with odds ratio and their confidence interval obtained from logistic regression. Compared with abstainers students who consumed only one alcohol unit had the risk of being a passenger in a car driven by a drunk driver increased by almost four times, students who reported using five or more units were increased by almost five times the risk of being involved in a car crash. Compared with students who consumed one alcohol unit, the risk of driving under the influence of alcohol increased four times in students using three alcohol units. Age group, use of illicit drugs, employment status, gender, and marital status significantly influenced occurrence of TRB among college students. Our study highlights the potential detrimental effects of low and moderate pattern of alcohol consumption and its relation to riding with an intoxicated driver and other TRB. These data suggest that targeted interventions should be implemented in order to prevent negative consequences due to alcohol use in this population. Copyright © 2012 Elsevier Inc.

Given the needs of these students, Mount St. Vincent University developed the Student Success Course (SSC, a 14-week intervention that offers instruction in learning strategies, selfmanagement, and motivation. The purpose of this study was to evaluate the effectiveness of the SSC for 100 undergraduates on academic probation. From pre- to post-test, participants reported a significant increase in cognitive strategies, study skills, and motivation as well as a significant decrease in test anxiety and procrastination (ps < .05. Over time, participants also demonstrated a significantly improved GPA (p < .0001. These results support the hypothesis that the SSC is an effective intervention, at least in the shortterm, for improving learning and motivational strategies in at risk students. Il est reconnu que les étudiants d’université dont les stratégies d’apprentissage sont inefficaces et qui ont une faible motivation risquent de souffrir de stress et d’obtenir de mauvaises notes.

    Recent progress in human pluripotent stem cell (hPSC) and genome editing technologies has opened up new avenues for the investigation of human biology in health and disease as well as the development of therapeutic applications. Gene editing approaches with programmable nucleases have been successfully established in hPSCs and applied to study gene function, develop novel animal models and perform genetic and chemical screens. Several studies now show the successful editing of disease-linked alleles in somatic and patient-derived induced pluripotent stem cells (iPSCs) as well as in animal models. Importantly, initial clinical trials have shown the safety of programmable nucleases for ex vivo somatic gene therapy. In this context, the unlimited proliferation potential and the pluripotent properties of iPSCs may offer advantages for gene targeting approaches. However, many technical and safety issues still need to be addressed before genome-edited iPSCs are translated into the clinical setting. Here, we provide an overview of the available genome editing systems and discuss opportunities and perspectives for their application in basic research and clinical practice, with a particular focus on hPSC based research and gene therapy approaches. Finally, we discuss recent research on human germline genome editing and its social and ethical implications. - Highlights: • Programmable nucleases have proven efficient and specific for genome editing in human pluripotent stem cells (hPSCs). • Genome edited hPSCs can be employed to study gene function in health and disease as well as drug and chemical screens. • Genome edited hPSCs hold great promise for ex vivo gene therapy approaches. • Technical and safety issues should be first addressed to advance the clinical use of gene-edited hPSCs.

    2002-01-01

    The authors introduce Photoshop 6.0 for radiologists and demonstrate basic techniques of editing gray-scale cross-sectional images intended for publication and for incorporation into computerized presentations. For basic editing of gray-scale cross-sectional images, the Tools palette and the History/Actions palette pair should be displayed. The History palette may be used to undo a step or series of steps. The Actions palette is a menu of user-defined macros that save time by automating an action or series of actions. Converting an image to 8-bit gray scale is the first editing function. Cropping is the next action. Both decrease file size. Use of the smallest file size necessary for the purpose at hand is recommended. Final file size for gray-scale cross-sectional neuroradiologic images (8-bit, single-layer TIFF [tagged image file format] at 300 pixels per inch) intended for publication varies from about 700 Kbytes to 3 Mbytes. Final file size for incorporation into computerized presentations is about 10-100 Kbytes (8-bit, single-layer, gray-scale, high-quality JPEG [Joint Photographic Experts Group]), depending on source and intended use. Editing and annotating images before they are inserted into presentation software is highly recommended, both for convenience and flexibility. Radiologists should find that image editing can be carried out very rapidly once the basic steps are learned and automated. Copyright RSNA, 2002

    Ajibade, Phoebe Butler

    2010-01-01

    This paper examined health behaviors (seatbelt use, tobacco use, and obesity status) of 127 black male college students using data obtained from the National College Health Risk Behavior Survey. The majority of the participants were freshmen and sophomores (70%), full time students (95%), and lived on campus (85%). The results indicated that black males often failed to use seatbelts while riding as a passenger (69%) or driving (48%). Although 15% of the students smoked, 1/3 of the smokers began smoking during college. Approximately 50% of the students were overweight or obese; among students attempting to lose weight, exercise versus nutrient intake was used as a means to lose weight. The study recommendations included the need to increase educational efforts to alert black males to their risks for a premature death, and to provide programming/mentoring initiatives to assist males in dealing with stress and discrimination that may impact their health-related decision making. The implications of this study suggest that even educated black males are at risk for premature disease and disability as a result of their health behaviors.

  4. The impact of continuity editing in narrative film on event segmentation.

    2011-01-01

    Filmmakers use continuity editing to engender a sense of situational continuity or discontinuity at editing boundaries. The goal of this study was to assess the impact of continuity editing on how people perceive the structure of events in a narrative film and to identify brain networks that are associated with the processing of different types of continuity editing boundaries. Participants viewed a commercially produced film and segmented it into meaningful events, while brain activity was recorded with functional magnetic resonance imaging (MRI). We identified three degrees of continuity that can occur at editing locations: edits that are continuous in space, time, and action; edits that are discontinuous in space or time but continuous in action; and edits that are discontinuous in action as well as space or time. Discontinuities in action had the biggest impact on behavioral event segmentation, and discontinuities in space and time had minor effects. Edits were associated with large transient increases in early visual areas. Spatial-temporal changes and action changes produced strikingly different patterns of transient change, and they provided evidence that specialized mechanisms in higher order perceptual processing regions are engaged to maintain continuity of action in the face of spatiotemporal discontinuities. These results suggest that commercial film editing is shaped to support the comprehension of meaningful events that bridge breaks in low-level visual continuity, and even breaks in continuity of spatial and temporal location.

    Hepatitis B virus (HBV) Infection is endemic in Nigeria. Healthcare students are more vulnerable because of direct contact with patients' body fluids and blood. Risk perception of HBV and HB vaccine uptake are also poor. The aim of this study was to assess the level of risk perception of hepatitis B infection, and uptake of the HBV vaccine, between medical and other students of the University of Jos. A comparative cross sectional study was conducted among 1,200 students of the departments of Medicine, Nursing sciences and Public Administration, University of Jos (400 from each arm) using a pretested self-administered questionnaire. A five point Likert scoring system was used to assess risk perception. Data was analyzed using SPSS version 20. A P -value of risk perception was 76.8%. This was also similar for medical and nursing students (40.7% and 40.1% respectively), but lower for public administration students (9.1%), PRisk perception is 5x higher among medical students compared to public administration students (OR = 5.22, 95% CI = 2.19 - 12.93; P risk perception on HBV infection are high among University of Jos students, but uptake of HB vaccine is low. Findings are worst for non-health students.

    To explore the incidence of suicide exposure and its association with suicide risk in Chinese college students, and study the modulatory effects of suicide exposure on the relations between life events and suicide risks. A total of 8202 college students from 12 Chinese colleges and universities in mainland China completed a cross-sectional survey that included suicidal behaviors questionnaire-revised (SBQ-R), Adolescent Self-Rating Life Events Check List (ASLEC), suicide exposure questionnaire, social and demographic characteristics questionnaire. The incidence of exposure to suicide events involving close relatives and acquaintances were 3.9% and 11.8% among sampled Chinese college students, respectively. Students exposed to suicide events involving close relatives had significantly higher total SBQ-R scores than those who did not (5.51∓2.44 vs 4.68∓2.11, P0.05), but exposure to acquaintance suicide events moderated the effects of life events on suicide risk (P<0.01), and the college students with a high level of life events and history of acquaintance suicide had the highest risk for suicide. In Chinese college students, the risk of suicide is closely associated with exposure to suicide events and life events, and exposure to suicide events involving acquaintances can modulate the effects of life events on suicide risk.

    2016-07-01

    Full Text Available In the domain of electronic edition, drama’s specificity has been considered in terms of metadata improvements and possibilities. At the same time, an increasing closeness between art history research and performance art has demonstrated its methodological value to assess the complex nature of the archive. My post-doctoral research follows the lead and goes as far as proposing that performance art can be an adequate methodology when preparing the electronic edition of eighteenth-century drama. Furthermore, “performing the archive” can help to fill the gap between the eventful nature of drama manuscripts and the audience of today, suggesting new ways of approaching the specific materiality of the plays.

    In Italy, inundation and landslides are widespread phenomena that impact the population and cause significant economic damage to private and public properties. The perception of the risk posed by these natural geo-hydrological hazards varies geographically and in time. The variation in the perception of the risks has negative consequences on risk management, and limits the adoption of effective risk reduction strategies. We maintain that targeted education can foster the understanding of geo-hydrological hazards, improving their perception and the awareness of the associated risk. Collaboration of a research center experienced in geo-hydrological hazards and risks (CNR IRPI, Perugia) and a high school (ITIS Alessandro Volta, Perugia) has resulted in the design and execution of a project aimed at improving the perception of geo-hydrological risks in high school students and teachers through software development. In the two-year project, students, high school teachers and research scientists have jointly developed software broadly related to landslide and flood hazards. User requirements and system specifications were decided to facilitate the distribution and use of the software among students and their peers. This allowed a wider distribution of the project results. We discuss two prototype software developed by the high school students, including an application of augmented reality for improved dissemination of information of landslides and floods with human consequences in Italy, and a crowd science application to allow students (and others, including their families and friends) to collect information on landslide and flood occurrence exploiting modern mobile devices. This information can prove important e.g., for the validation of landslide forecasting models.

    Adenosine-to-inosine RNA editing diversifies the transcriptome and promotes functional diversity, particularly in the brain. A plethora of editing sites has been recently identified; however, how they are selected and regulated and which are functionally important are largely unknown. Here we show the cis-regulation and stepwise selection of RNA editing during Drosophila evolution and pinpoint a large number of functional editing sites. We found that the establishment of editing and variation in editing levels across Drosophila species are largely explained and predicted by cis-regulatory elements. Furthermore, editing events that arose early in the species tree tend to be more highly edited in clusters and enriched in slowly-evolved neuronal genes, thus suggesting that the main role of RNA editing is for fine-tuning neurological functions. While nonsynonymous editing events have been long recognized as playing a functional role, in addition to nonsynonymous editing sites, a large fraction of 3'UTR editing sites is evolutionarily constrained, highly edited, and thus likely functional. We find that these 3'UTR editing events can alter mRNA stability and affect miRNA binding and thus highlight the functional roles of noncoding RNA editing. Our work, through evolutionary analyses of RNA editing in Drosophila, uncovers novel insights of RNA editing regulation as well as its functions in both coding and non-coding regions.

    Energy issues such as pollution, resource depletion, global warming, nuclear power and waste are problems that demand timely solutions. This book provides a critical examination of the resources, market forces, and social impacts of modern energy production. The book addresses the dilemmas that have arisen due to society's crucial dependence on energy, particularly fossil fuels, and explores the available alternative energy producing technologies. The second edition has increased emphasis on those issues at the forefront of the current energy debate: energy sustainability, climate change, and the radical restructuring of the power industry due to de-regulation. Assuming no prior technical expertise and avoiding complex mathematical formulation, it is directed at a broad readership. The second edition will follow the first in proving especially useful as a textbook for undergraduate programs in Science, Technology and Society (STS), and as a supplementary text in a variety of courses which touch upon energy studies, including environmental and technology policy, environmental, mineral and business law, energy and resource economics. Fully updated second edition of successful first edition that was adopted on Science, Technology and Society courses Provides a critical examination of all aspects of modern energy production for non-technical readers For a broad readership from a variety of backgrounds

  15. Engineered Viruses as Genome Editing Devices

    2016-01-01

    Genome editing based on sequence-specific designer nucleases, also known as programmable nucleases, seeks to modify in a targeted and precise manner the genetic information content of living cells. Delivering into cells designer nucleases alone or together with donor DNA templates, which serve as surrogate homologous recombination (HR) substrates, can result in gene knockouts or gene knock-ins, respectively. As engineered replication-defective viruses, viral vectors are having an increasingly important role as delivery vehicles for donor DNA templates and designer nucleases, namely, zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs) and clustered, regularly interspaced, short palindromic repeats (CRISPR)-associated Cas9 (CRISPR−Cas9) nucleases, also known as RNA-guided nucleases (RGNs). We review this dual role played by engineered viral particles on genome editing while focusing on their main scaffolds, consisting of lentiviruses, adeno-associated viruses, and adenoviruses. In addition, the coverage of the growing body of research on the repurposing of viral vectors as delivery systems for genome editing tools is complemented with information regarding their main characteristics, pros, and cons. Finally, this information is framed by a concise description of the chief principles, tools, and applications of the genome editing field as a whole. PMID:26336974

    Risk sexual practice among students from public universities/colleges is common in Ethiopia. However, little has been known about risk sexual behavior of students in private colleges where more students are potentially enrolled. Therefore, this study aimed to assess the magnitude of risky sexual behaviors and predictors among students of Private Colleges in Mekelle City. A mixed design of both quantitative and qualitative methods was used among 627 randomly selected students of private colleges from February to march 2013. Self administered questionnaire and focus group discussion was used to collect data. A thematic content analysis was used for the qualitative part. For the quantitative study, Univariate, Bivariate and multivariable analysis was made using SPSS version 16 statistical package and p value less than 0.05 was used as cut off point for a statistical significance. Among the total 590 respondents, 151 (29.1%) have ever had sex. Among the sexually active students, 30.5% reported having had multiple sexual partners and consistent condom use was nearly 39%. In multivariable logistic regression analysis, variables such as sex, age group, sex last twelve months and condom use last twelve months was found significantly associated with risky sexual behavior. The findings of qualitative and quantitative study showed consistency in presence of risk factors. Finding of this study showed sexual risk behaviors is high among private colleges such as multiple sexual partners and substance use. So that colleges should emphasis on promoting healthy sexual and reproductive health programs.

    RNA editing is a post-transcriptional molecular process whereby the information in a genetic message is modified from that in the corresponding DNA template by means of nucleotide substitutions, insertions and/or deletions. It occurs mostly in organelles by clade-specific diverse and unrelated biochemical mechanisms. RNA editing events have been annotated in primary databases as GenBank and at more sophisticated level in the specialized databases REDIdb, dbRES and EdRNA. At present, REDIdb is the only freely available database that focuses on the organellar RNA editing process and annotates each editing modification in its biological context. Here we present an updated and upgraded release of REDIdb with a web-interface refurbished with graphical and computational facilities that improve RNA editing investigations. Details of the REDIdb features and novelties are illustrated and compared to other RNA editing databases. REDIdb is freely queried at http://biologia.unical.it/py_script/REDIdb/.

    1989-12-01

    Comparative sequence analysis of genomic and complementary DNA clones from several mitochondrial genes in the higher plant Oenothera revealed nucleotide sequence divergences between the genomic and the messenger RNA-derived sequences. These sequence alterations could be most easily explained by specific post-transcriptional nucleotide modifications. Most of the nucleotide exchanges in coding regions lead to altered codons in the mRNA that specify amino acids better conserved in evolution than those encoded by the genomic DNA. Several instances show that the genomic arginine codon CGG is edited in the mRNA to the tryptophan codon TGG in amino acid positions that are highly conserved as tryptophan in the homologous proteins of other species. This editing suggests that the standard genetic code is used in plant mitochondria and resolves the frequent coincidence of CGG codons and tryptophan in different plant species. The apparently frequent and non-species-specific equivalency of CGG and TGG codons in particular suggests that RNA editing is a common feature of all higher plant mitochondria.

    The emergence of clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-Cas9) gene editing systems has enabled the creation of specific mutants at low cost, in a short time and with high efficiency, in eukaryotic cells. Since a CRISPR-Cas9 system typically creates an array of mutations in targeted sites, a successful gene editing project requires careful selection of edited clones. This process can be very challenging, especially when working with multiallelic genes and/or polyploid cells (such as cancer and plants cells). Here we described a next-generation sequencing method called CRISPR-Cas9 Edited Site Sequencing (CRES-Seq) for the efficient and high-throughput screening of CRISPR-Cas9-edited clones. CRES-Seq facilitates the precise genotyping up to 96 CRISPR-Cas9-edited sites (CRES) in a single MiniSeq (Illumina) run with an approximate sequencing cost of $6/clone. CRES-Seq is particularly useful when multiple genes are simultaneously targeted by CRISPR-Cas9, and also for screening of clones generated from multiallelic genes/polyploid cells. © 2018 by John Wiley & Sons, Inc.

  4. Statistical optimisation techniques in fatigue signal editing problem

    2015-01-01

    Success in fatigue signal editing is determined by the level of length reduction without compromising statistical constraints. A great reduction rate can be achieved by removing small amplitude cycles from the recorded signal. The long recorded signal sometimes renders the cycle-to-cycle editing process daunting. This has encouraged researchers to focus on the segment-based approach. This paper discusses joint application of the Running Damage Extraction (RDE) technique and single constrained Genetic Algorithm (GA) in fatigue signal editing optimisation.. In the first section, the RDE technique is used to restructure and summarise the fatigue strain. This technique combines the overlapping window and fatigue strain-life models. It is designed to identify and isolate the fatigue events that exist in the variable amplitude strain data into different segments whereby the retention of statistical parameters and the vibration energy are considered. In the second section, the fatigue data editing problem is formulated as a constrained single optimisation problem that can be solved using GA method. The GA produces the shortest edited fatigue signal by selecting appropriate segments from a pool of labelling segments. Challenges arise due to constraints on the segment selection by deviation level over three signal properties, namely cumulative fatigue damage, root mean square and kurtosis values. Experimental results over several case studies show that the idea of solving fatigue signal editing within a framework of optimisation is effective and automatic, and that the GA is robust for constrained segment selection

    Bladder cancer-associated protein (BLCAP) is a highly conserved protein among species, and it is considered a novel candidate tumor suppressor gene originally identified from human bladder carcinoma. However, little is known about the regulation or the function of this protein. Here, we show that the human BLCAP transcript undergoes multiple A-to-I editing events. Some of the new editing events alter the highly conserved amino terminus of the protein creating alternative protein isoforms by changing the genetically coded amino acids. We found that both ADAR1 and ADAR2-editing enzymes cooperate to edit this transcript and that different tissues displayed distinctive ratios of edited and unedited BLCAP transcripts. Moreover, we observed a general decrease in BLCAP-editing level in astrocytomas, bladder cancer and colorectal cancer when compared with the related normal tissues. The newly identified editing events, found to be downregulated in cancers, could be useful for future studies as a diagnostic tool to distinguish malignancies or epigenetic changes in different tumors.

    2014-09-01

    Unconventional shale resources may contain a significant amount of hydrogen in organic solids such as kerogen, but it is not possible to directly detect these solids with many NMR systems. Binomial-edited pulse sequences capitalize on magnetization transfer between solids, semi-solids, and liquids to provide an indirect method of detecting solid organic materials in shales. When the organic solids can be directly measured, binomial-editing helps distinguish between different phases. We applied a binomial-edited CPMG pulse sequence to a range of natural and experimentally-altered shale samples. The most substantial signal loss is seen in shales rich in organic solids while fluids associated with inorganic pores seem essentially unaffected. This suggests that binomial-editing is a potential method for determining fluid locations, solid organic content, and kerogen-bitumen discrimination. Copyright © 2014 Elsevier Inc.

    2012-01-01

    In this paper we present two communication protocols on computing edit distance. In our first result, we give a one-way protocol for the following Document Exchange problem. Namely given x ∈ Σn to Alice and y ∈ Σn to Bob and integer k to both, Alice sends a message to Bob so that he learns x...... or truthfully reports that the edit distance between x and y is greater than k. For this problem, we give a randomized protocol in which Alice transmits at most O ˜ (klog 2 n) bits and each party’s time complexity is O ˜ (nlogn+k 2 log 2 n) . Our second result is a simultaneous protocol for edit distance over...... permutations. Here Alice and Bob both send a message to a third party (the referee) who does not have access to the input strings. Given the messages, the referee decides if the edit distance between x and y is at most k or not. For this problem we give a protocol in which Alice and Bob run a O...

    Full Text Available Genome editing is a powerful tool to study the function of specific genes and proteins important for development or disease. Recent technologies, especially CRISPR/Cas9 which is characterized by convenient handling and high precision, revolutionized the field of genome editing. Such tools have enormous potential for basic science as well as for regenerative medicine. Nevertheless, there are still several hurdles that have to be overcome, but patient-tailored therapies, termed precision medicine, seem to be within reach. In this review, we focus on the achievements and limitations of genome editing in the cardiovascular field. We explore different areas of cardiac research and highlight the most important developments: (1 the potential of genome editing in human pluripotent stem cells in basic research for disease modelling, drug screening, or reprogramming approaches and (2 the potential and remaining challenges of genome editing for regenerative therapies. Finally, we discuss social and ethical implications of these new technologies.

A better understanding of related risk factors can help target appropriate support services for them. The aim of the study was to assess the occurrence of depression and identify its risk factors among undergraduate students in a medical College in Kolkata, India. Methodology: A descriptive, cross-sectional study using a two stage, stratified cluster sampling technique was used to select a sample of 289 students. Data were collected using a self-administered, anonymous questionnaire based on Becks Depression Inventory II. Results: The mean score of students on depression scale was 10.47±10.39. 22.5 % of students tested positive for some form of depression while 6.2% had severe to extreme depression. The risk factors of depressive symptoms identified were older age, lower family income, students who did not choose admission in MBBS course on their own, had addictions, felt negatively about results, faced difficulty with study course and had relationship issues. Students with relationship issues in their personal lives were 3.7 times more likely to exhibit depressive symptoms than without them. Students who faced difficulty coping with study course were 2.18 times more likely to exhibit depressive symptoms than without them. Conclusion: Academic performance alone doesn’t influence the mental health of students, rather factors like older age, socioeconomic status, role in choice of medical career, negative perception of academic performance, difficulty with study course and relationship issues are also important.

    Full Text Available Abstract Background Alcohol drinking is frequently related to behavioral problems, which lead to a number of negative consequences. This study was to evaluate the characteristics of male high school students who drink, the drinking patterns among them, and the associations between current drinking and other health risk behaviors which focused on personal safety, violence-related behaviors, suicide and sexual behaviors. Method A cross-sectional study was conducted to explore current alcohol drinking and health-risk behaviors among male high school students in central Thailand. Five thousand one hundred and eighty four male students were classified into 2 groups according to drinking in the previous 30 days (yes = 631, no = 4,553. Data were collected by self-administered, anonymous questionnaire which consisted of 3 parts: socio-demographic factors, health-risk behaviors and alcohol drinking behavior during the past year from December 2007 to February 2008. Results The results showed that the percent of current drinking was 12.17. Most of them were 15-17 years (50.21%. Socio-demographic factors such as age, educational level, residence, cohabitants, grade point average (GPA, having a part time job and having family members with alcohol/drug problems were significantly associated with alcohol drinking (p Conclusions An increased risk of health-risk behaviors, including driving vehicles after drinking, violence-related behaviors, sad feelings and attempted suicide, and sexual behaviors was higher among drinking students that led to significant health problems. Effective intervention strategies (such as a campaign mentioning the adverse health effects and social consequences to the risk groups, and encouraging parental and community efforts to prevent drinking among adolescents should be implemented to prevent underage drinking and adverse consequences.

    This cross-sectional study investigated self-esteem in relation to age, gender, ethnicity, and risk behaviors among a sample of nonmainstream students. Participants were 149 students in the 6th to 12th grades from two nonmainstream schools (one charter and one alternative school). Self-esteem and youth risk behaviors were determined by using a modified version of the Rosenberg Self-Esteem Scale (Rosenberg, 1965) and the National Alternative High School Youth Risk Behavior Survey (Grunbaum et al., 1999), respectively. Results indicated that nonmainstream students with high self-esteem were more likely to engage in their first sexual experience and to begin marijuana use later in life. African American students reported having their first sexual experience at an older age, but having more sexual partners than did Latino students. The implications of these findings are discussed.

    There exists a significant gap in vaccine coverage of the human papillomavirus (HPV) among college-aged students. This study assessed sexual risk-taking behavior among university students and analyzed predictors of HPV vaccine initiation and completion in this population. Data (n = 746) were from an anonymous online, cross-sectional survey distributed to university students, between the ages of 19-26 years, at a private Midwestern university. Both chi-square and multivariable logistics regression models estimated the association between sociodemographic characteristics and sexual risk factors (including number of vaginal sexual partners, number of oral sexual partners, initiation of oral sex, and initiation of vaginal sex), with HPV vaccine initiation and completion. A significant number of participants (40%) had not received a single dose of the HPV vaccine series. Of those who initiated the series, more than half (51%) did not achieve completion. Additionally, a greater number of participants have had multiple (4 or more) oral sexual partners than vaginal sexual partners (25.7% vs. 20.3%). After adjusting for covariates, it was found that sexual risk factors were not significantly associated with HPV vaccine initiation or completion. HPV vaccine initiation and completion rates are suboptimal among university students. High levels of sexual-risk taking behaviors associated with HPV infection persist, yet are not significant predictors of HPV vaccine behaviors in this age group. To increase uptake among 18-26-year-old students, future public health interventions should focus on HPV vaccine education and uptake across the entire population, irrespective of sexual risk profile.

    The present survey was designed to investigate the perception of health risks among college students in China. The data are the responses of a sample of 3,069 college students at one university to surveys that include measures of several dimensions of public judgments about fifteen specific hazards. Chinese college students conveyed their concerns as falling into three broad categories: Environmental (e.g., global warming, natural catastrophes, the ozone hole, air pollution, chemical pollution, pesticides in food), Technological (e.g., nuclear power stations, thermal power, genetically modified food, medical X-rays), and Social (cigarette smoking, drinking alcohol, overtime study or work, mental stress, motor vehicle accidents). The data were collected with a self-report questionnaire. Descriptive statistics were used to illustrate the levels of perceived risk according to the percent of “high risk” responses as well as the mean response values. Generally, the hazards that were perceived as posing the greatest health risk were those belonging to the social health risks; items related to technology risks received the lowest percentage of “high health risk” rankings. Traditional environmental risks such as natural catastrophes, pollution issues (chemical pollution, air pollution), and pesticides in food were ranked as being relatively high risks. The respondents were less concerned about new emerging issues and long-term environmental risks (global warming). In this survey, motor vehicle accidents were considered to be a “high health risk” by the greatest percentage of respondents. Generally speaking, the female respondents’ degree of recognition of health risks is higher than that of male respondents. Only for the item of smoking was the male respondents’ degree higher than that of females. There is also a geographic imbalance in the health risk perceptions. The degree of recognition of health risks from respondents in municipalities is generally

    Individuals' perceptions of risk have implications for whether and how they engage with protective strategies. This study investigated how sexual risk, specifically HIV and pregnancy and responsibility for these risks were constructed in discussions across five groups of youth in KwaZulu-Natal, South Africa. The qualitative study used focus groups and interviews with a sample of 28 tertiary level students and 7 peri-urban youth. The constructions of risk intersected with raced and gendered narratives around sexual risk and responsibility. These constructions were used by the participants to assign and displace responsibility for the risks of HIV and pregnancy, rendering some groups immune to these risks. This constitutes a form of stigmatisation and also has implications for participants' prevention practices.

    Most journals try to improve their articles by technical editing processes such as proof-reading, editing to conform to 'house styles', grammatical conventions and checking accuracy of cited references. Despite the considerable resources devoted to technical editing, we do not know whether it improves the accessibility of biomedical research findings or the utility of articles. This is an update of a Cochrane methodology review first published in 2003. To assess the effects of technical editing on research reports in peer-reviewed biomedical journals, and to assess the level of accuracy of references to these reports. We searched The Cochrane Library Issue 2, 2007; MEDLINE (last searched July 2006); EMBASE (last searched June 2007) and checked relevant articles for further references. We also searched the Internet and contacted researchers and experts in the field. Prospective or retrospective comparative studies of technical editing processes applied to original research articles in biomedical journals, as well as studies of reference accuracy. Two review authors independently assessed each study against the selection criteria and assessed the methodological quality of each study. One review author extracted the data, and the second review author repeated this. We located 32 studies addressing technical editing and 66 surveys of reference accuracy. Only three of the studies were randomised controlled trials. A 'package' of largely unspecified editorial processes applied between acceptance and publication was associated with improved readability in two studies and improved reporting quality in another two studies, while another study showed mixed results after stricter editorial policies were introduced. More intensive editorial processes were associated with fewer errors in abstracts and references. Providing instructions to authors was associated with improved reporting of ethics requirements in one study and fewer errors in references in two studies, but no

    1987-01-01

    The authors developed a cost-effective approach to imaging studies, based on initial selection of an exam that best addresses the specific clinical problem and obviates the need for additional diagnostic tests. Tightly reasoned arguments compare available imaging options with respect to diagnostic yield, feasibility, risk, and cost. To aid the clinician in making cost comparisons, each paper of the Second Edition lists the dollar cost of relevant imaging studies. The Second Edition has been thoroughly revised to reflect the important advances in diagnostic imaging of the past three years, highlighting CT's expanding role in thoracic and abdominal problems, magnetic resonance imaging as a spectacular diagnostic tool for the central nervous system, and the clinical application of many newly-developed radiopharmaceuticals. New chapters cover breast cancer screening, acute spinal trauma, search for primary cancer of unknown origin, acute anuria, blunt chest trauma, new onset seizures, and spinal cord compression from metastases. Other papers have been rewritten for greater clarity and to incorporate new techniques, like dipyridamole stress testing. A glossary and an introduction define and explain the capabilities and limitations of current techniques

A train carrying radioactive waste had begun its trip in New York and was close to its destination in California. As it stopped, the engineer called to a bystander, "Congratulations." "What for?" said the man. "You get to die. We calculated that each person along the route would receive one-millionth of the lethal dose of radioactivity. No one has died yet and you are the millionth person." "But I have received only one-millionth of the lethal dose." "That doesn't matter, it's a question of statistics." (This story is paraphrased from Rockwell's piece in The Scientist, March 16, 1998, p 7.) What Risk? contains 15 chapters (by 19 authors) arranged in five categories: methodology, science, science policy, commentaries, and perception. It deals in different ways, broadly speaking, with the problems raised by this anecdote. It would make a splendid textbook for high-school students or college undergraduates for a course dealing with pitfalls in extrapolation, unexpected variables, the proper use of statistics, political correctness and absolute safety, evaluation of the scientific literature, and the interplay of science and politics. Each article has an extensive reference list. Among the specific risks discussed are asbestos, benzene, environmental (secondhand) tobacco smoke, dioxin, ionizing radiation, and carcinogens. Some general principles emerge. (i) Since all organisms have repair mechanisms against environmental damage, there are thresholds for all damaging agents. Therefore, extrapolation from high dose rates to very low levels does not make sense. (ii) Doses and dose rates should not be confused. (iii) There are very large species differences in response to damaging agents. (iv) Unrecognized variables lurk everywhere. (v) The costs of enforcing demonstrably false standards are huge. Here are some illustrations. Nilsson

    Full Text Available To determine whether involvement in bullying as a bully, victim, or bully-victim was associated with a higher risk of poor sleep quality among high school students in China.A cross-sectional study was conducted. A total of 23,877 high school students were surveyed in six cities in Guangdong Province. All students were asked to complete the adolescent health status questionnaire, which included the Chinese version of the Pittsburgh Sleep Quality Index (PSQI and bullying involvement. Descriptive statistics were used to evaluate sleep quality and the prevalence of school bullying. Multi-level logistic regression analyses were conducted to examine the association between being victimized and bullying others with sleep quality.Among the 23,877 students, 6,127 (25.66% reported having poor sleep quality, and 10.89% reported being involved in bullying behaviors. Of the respondents, 1,410 (5.91% were pure victims of bullying, 401 (1.68% were bullies and 784 (3.28% were bully-victims. Frequently being involved in bullying behaviors (being bullied or bullying others was related to increased risks of poor sleep quality compared with adolescents who were not involved in bullying behaviors.

  14. Genome editing and assisted reproduction: curing embryos, society or prospective parents?

    Science.gov (United States)

    Cavaliere, Giulia

    2018-06-01

    This paper explores the ethics of introducing genome-editing technologies as a new reproductive option. In particular, it focuses on whether genome editing can be considered a morally valuable alternative to preimplantation genetic diagnosis (PGD). Two arguments against the use of genome editing in reproduction are analysed, namely safety concerns and germline modification. These arguments are then contrasted with arguments in favour of genome editing, in particular with the argument of the child's welfare and the argument of parental reproductive autonomy. In addition to these two arguments, genome editing could be considered as a worthy alternative to PGD as it may not be subjected to some of the moral critiques moved against this technology. Even if these arguments offer sound reasons in favour of introducing genome editing as a new reproductive option, I conclude that these benefits should be balanced against other considerations. More specifically, I maintain that concerns regarding the equality of access to assisted reproduction and the allocation of scarce resources should be addressed prior to the adoption of genome editing as a new reproductive option.

    Adenosine deaminases acting on RNA (ADARs) are zinc-containing enzymes that deaminate adenosine bases to inosines within dsRNA regions in transcripts. In short, structured dsRNA hairpins individual adenosine bases may be targeted specifically and edited with up to one hundred percent efficiency, leading to the production of alternative protein variants. However, the majority of editing events occur within longer stretches of dsRNA formed by pairing of repetitive sequences. Here, many different adenosine bases are potential targets but editing efficiency is usually much lower. Recent work shows that ADAR-mediated RNA editing is also required to prevent aberrant activation of antiviral innate immune sensors that detect viral dsRNA in the cytoplasm. Missense mutations in the ADAR1 RNA editing enzyme cause a fatal auto-inflammatory disease, Aicardi-Goutières syndrome (AGS) in affected children. In addition RNA editing by ADARs has been observed to increase in many cancers and also can contribute to vascular disease. Thus the role of RNA editing in the progression of various diseases can no longer be ignored. The ability of ADARs to alter the sequence of RNAs has also been used to artificially target model RNAs in vitro and in cells for RNA editing. Potentially this approach may be used to repair genetic defects and to alter genetic information at the RNA level. In this review we focus on the role of ADARs in disease development and progression and on their potential use to artificially modify RNAs in a targeted manner.

  19. Teaching flood risk management to secondary school students via the web

    2009-04-01

    Websites are getting increasingly important as a means to inform different groups in society about a large range of subjects. Especially young people use the internet frequently as a source of knowledge. When asked to develop educational material about flood risk management, we therefore chose to develop a website. Junior Floodsite, part of the larger Floodsite project, is developed for secondary school students around 15 or 16 years old, and their teachers, in all countries in Europe. Websites are common, but not for an audience and purpose like this. We asked a group of teachers and students to advise us and test the material we developed. Although children this age use the web a lot, this does not mean that anything you put on, will be used. To reach secondary school children about natural hazards such as floods, is not an easy thing. Amongst the masses of fun things to do on the internet, flood risk management will not stand out automatically. For students it had to be interesting, fun and useful. But not every student wants the same thing. Teachers informed us that for them it is important that the material fits seamlessly into the curriculum. They will then more readily employ the material. But in every country the curriculum is different (and even within countries they differ) and we could not make material for each individual country. To tackle these problems we decided to take a dual approach. On the one hand, we made the website flexible and modular with blocks of information and also activities like assignments, a virtual tour in Google Earth and games. Students and teachers can use those parts that they find interesting, fun or useful. On the other hand, we developed sets of structured lessons that teachers can directly put to use in their classrooms. The material on the website is written in English because most European students learn that language in school, but besides that it is also available in Dutch. Translations into other languages is welcomed

    2014-01-01

    Adenosine-to-inosine editing is one of the most frequent post-transcriptional modifications, manifested as A-to-G mismatches when comparing RNA sequences with their source DNA. Recently, a number of RNA-seq data sets have been screened for the presence of A-to-G editing, and hundreds of thousands of editing sites identified. Here we show that existing screens missed the majority of sites by ignoring reads with excessive (‘hyper’) editing that do not easily align to the genome. We show that careful alignment and examination of the unmapped reads in RNA-seq studies reveal numerous new sites, usually many more than originally discovered, and in precisely those regions that are most heavily edited. Specifically, we discover 327,096 new editing sites in the heavily studied Illumina Human BodyMap data and more than double the number of detected sites in several published screens. We also identify thousands of new sites in mouse, rat, opossum and fly. Our results establish that hyper-editing events account for the majority of editing sites. PMID:25158696

    2017-09-01

    With the development of the third-generation gene scissors, CRISPR-Cas9, concerns are being raised about ethical and social repercussions of the new gene-editing technology. In this situation, this article explores the legislation and interpretation of the positive laws in South Korea. The BioAct does not specify and regulate 'gene editing' itself. However, assuming that genetic editing is used in the process of research and treatment, we can look to the specific details of the regulations for research on humans as well as gene therapy research in order to see how genetic editing is regulated under the BioAct. BioAct differentiates the regulation between (born) humans and embryos etc. and the regulation differ entirely in the manner and scope. Moreover, due to the fact that gene therapy products are regarded as drugs, they fall under different regulations. The Korean Pharmacopoeia Act put stringent sanctions on clinical trials for gene therapy products and the official Notification "Approval and Examination Regulations for Biological Products, etc." by Food and Drug Safety Administration may be applied to gene editing for gene therapy purposes.

Directed by a guide RNA, a Cas effector introduces a double stranded break in DNA and host cell DNA repair leads to the introduction of errors (e.g., to knockout a gene) or a programmed change. Introduction of a Cas effector and guide RNA as a purified Cas ribonucleoprotein complex (CasRNP) has recently emerged as a powerful approach to alter cell types and organisms. Not only does CasRNP editing exhibit increased efficacy and specificity, it avoids optimization and iteration of species-specific factors such as codon usage, promoters, and terminators. CasRNP editing has been rapidly adopted for research use in many contexts and is quickly becoming a popular method to edit primary cells for therapeutic application. This article describes how to make a Cas9 RNP and outlines its use for gene editing in human cells. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley & Sons, Inc.

  5. Safety, Security, and Policy Considerations for Plant Genome Editing.

    Wolt, Jeffrey D

    2017-01-01

    Genome editing with engineered nucleases (GEEN) is increasingly used as a tool for gene discovery and trait development in crops through generation of targeted changes in endogenous genes. The development of the CRISPR-Cas9 system (clustered regularly interspaced short palindromic repeats with associated Cas9 protein), in particular, has enabled widespread use of genome editing. Research to date has not comprehensively addressed genome-editing specificity and off-target mismatches that may result in unintended changes within plant genomes or the potential for gene drive initiation. Governance and regulatory considerations for bioengineered crops derived from using GEEN will require greater clarity as to target specificity, the potential for mismatched edits, unanticipated downstream effects of off-target mutations, and assurance that genome reagents do not occur in finished products. Since governance and regulatory decision making involves robust standards of evidence extending from the laboratory to the postcommercial marketplace, developers of genome-edited crops must anticipate significant engagement and investment to address questions of regulators and civil society. © 2017 Elsevier Inc.

    2013-07-01

    The IEA Wind Power Technology Roadmap 2013 Edition recognises the very significant progress made since the first edition was published in 2009. The technology continues to improve rapidly, and costs of generation from land-based wind installations continue to fall. Wind power is now being deployed in countries with good resources without any dedicated financial incentives. The 2013 Edition targets an increased share (15% to 18%) of global electricity to be provided by wind power in 2050, compared to 12% in the original roadmap of 2009. However, increasing levels of low-cost wind still require predictable, supportive regulatory environments and appropriate market designs. The challenges of integrating higher levels of variable wind power into the grid need to be addressed. For offshore wind, much remains to be done to develop appropriate large-scale systems and to reduce costs. The 2013 Wind Power Roadmap also provides updated analysis on the barriers that exist for the technology and suggests ways to address them, including legal and regulatory recommendations.

    This study evaluated second-, third-, and fourth-year dental students' ability to identify systemic conditions associated with periodontal disease, risk factors most important for referral, and medications with an effect on the periodontium and their ability to apply this knowledge to make clinical decisions regarding treatment and referral of periodontal patients. A twenty-one question survey was administered at one U.S. dental school in the spring semester of 2012 to elicit the students' knowledge and confidence regarding clinical reasoning. The response rate was 86 percent. Periodontal risk factors were accurately selected by at least 50 percent of students in all three classes; these were poorly controlled diabetes, ≥6 mm pockets posteriorly, and lack of response to previous non-surgical therapy. Confidence in knowledge, knowledge of risk factors, and knowledge of medications with an effect on the periodontium improved with training and were predictive of better referral decision making. The greatest impact of training was seen on the students' ability to make correct decisions about referral and treatment for seven clinical scenarios. Although the study found a large increase in the students' abilities from the second through fourth years, the mean of 4.6 (out of 7) for the fourth-year students shows that, on average, those students missed correct treatment or referral on more than two of seven clinical cases. These results suggest that dental curricula should emphasize more critical decision making with respect to referral and treatment criteria in managing the periodontal patient.

    Full Text Available The optional subject Information and Communication Technology (ICT in obligatory secondary education is fundamentally about how to use applications. The software related to this subject is based on: photo editing programs, 3D constructions, sound editing and video editing. These can be viewed in isolation and independently or as a part of a comprehensive project in which students have to handle all of them at once. This article will explain a project with students: the virtual reconstruction of the thermal area of the roman villa of Balazote (Albacete. The goal was to improve student motivation and get actively involved in their learning process. Students used computers and classes of the course to conduct such research. First, the necessary information was sought, and then, based on that information and using different software about virtual reconstruction and recording and editing films: Gimp, SketchUP, Movie Maker, etc., our film was made. The result of this work is a film consisting of a virtual tour inside the roman villa.

    Full Text Available Abstract Background Forward planning and preventative measures before travelling can significantly reduce the risk of many vaccine preventable travel-related infectious diseases. Higher education students may be at an increased risk of importing infectious disease as many undertake multiple visits to regions with higher infectious disease endemicity. Little is known about the health behaviours of domestic or international university students, particularly students from low resource countries who travel to high-resource countries for education. This study aimed to assess travel-associated health risks and preventative behaviours in a sample of both domestic and international university students in Australia. Methods In 2010, a 28 item self-administered online survey was distributed to students enrolled at the University of New South Wales, Sydney, Australia. Multiple methods of distributing links to the online survey were utilised. The survey examined the international travel history, travel intentions, infection control behaviours and self-reported vaccination history. Results A total of 1663 respondents completed the online survey, 22.1% were international students and 83.9% were enrolled at an undergraduate level. Half had travelled internationally in the previous 12 months, with 69% of those travelling only once during that time with no difference in travel from Australia between domestic and international students (p = 0.8. Uptake of pre-travel health advice was low overall with 68% of respondents reporting they had not sought any advice from a health professional prior to their last international trip. Domestic students were more likely to report uptake of a range of preventative travel health measures compared to international students, including diarrhoeal medication, insect repellent, food avoidance and condoms (P Conclusions Our study highlights the need to educate students about the risk associated with travel and improve preventative

  18. Regulatory factors governing adenosine-to-inosine (A-to-I) RNA editing.

    Science.gov (United States)

    Hong, HuiQi; Lin, Jaymie Siqi; Chen, Leilei

    2015-03-31

    Adenosine-to-inosine (A-to-I) RNA editing, the most prevalent mode of transcript modification in higher eukaryotes, is catalysed by the adenosine deaminases acting on RNA (ADARs). A-to-I editing imposes an additional layer of gene regulation as it dictates various aspects of RNA metabolism, including RNA folding, processing, localization and degradation. Furthermore, editing events in exonic regions contribute to proteome diversity as translational machinery decodes inosine as guanosine. Although it has been demonstrated that dysregulated A-to-I editing contributes to various diseases, the precise regulatory mechanisms governing this critical cellular process have yet to be fully elucidated. However, integration of previous studies revealed that regulation of A-to-I editing is multifaceted, weaving an intricate network of auto- and transregulations, including the involvement of virus-originated factors like adenovirus-associated RNA. Taken together, it is apparent that tipping of any regulatory components will have profound effects on A-to-I editing, which in turn contributes to both normal and aberrant physiological conditions. A complete understanding of this intricate regulatory network may ultimately be translated into new therapeutic strategies against diseases driven by perturbed RNA editing events. Herein, we review the current state of knowledge on the regulatory mechanisms governing A-to-I editing and propose the role of other co-factors that may be involved in this complex regulatory process.

    Full Text Available Context: Hypertension in youth is increasing, but there is a dearth of data about the knowledge of risk factors in this age group. Aims: To assess the knowledge of risk factors of hypertension among university students and associate it with the blood pressure, physical activity, family history of cardiovascular disease (CVD, and sociodemographic variables. Materials and Methods: A cross-sectional survey among students enrolled in the first year, in the four academic programs, with the use of a validated, self-administered questionnaire on physical activity in the past 30 days and knowledge of risk factors of hypertension. A score of 6 on 11 was considered as good knowledge for modifiable risk factors. Blood pressure was also measured. The data was analyzed using PASW-17, Chi square test, and binary logistic regression analysis was done. Results: Of the 110 participants, 69.2% were < 20 years of age, 76.4% were females, and 40% were Arabs. Stress, high cholesterol, obesity, and smoking were identified as risk factors by 75.5, 73.6, 77.6, and 71.8%, respectively; 69.1% considered high salt intake and 62.7% considered high calorie diet as risk factors. Energy drink was considered as a risk factor by 64.5%, coffee consumption 35.5%, physical inactivity 47%, and oral contraceptives 13.6%. Half the group did not consider a family history of CVD as a risk factor, 60% did not consider older age as a risk factor, and 88% did not think male gender was a risk factor. Knowledge of modifiable risk factors was better than that of non-modifiable risk factors. Although nationality, course of study, raised blood pressure, and history of diabetes showed significant association with good knowledge, their net effect was not significant by the Adjusted Odd′s Ratio. Conclusions: The study identified some gaps in knowledge regarding both modifiable and non-modifiable risk factors of hypertension among students. A larger study would enable health promotion activities

    2001-10-01

    A socioculturally appropriate health risk behavior instrument, modeled after the U.S. Centers for Disease Control and Prevention's Youth Risk Behavior Survey (YRBS), was administered to 717 secondary school students in a rural area of Zimbabwe. Comparisons of risk behaviors by gender and school grade were made using univariate procedures and multiple logistic regression. Males were significantly more likely than females to have had sexual intercourse (odds ratio = 5.02, p < .0001) and to report drug use behaviors. Males also were significantly more likely to report early initiation (by age 13 years) of alcohol use, cigarette smoking, and marijuana use. School site violence and drug use behaviors also were prevalent in this sample. An interaction between gender and grade was evident for some behaviors. Additional research may further the understanding of these risk behaviors and facilitate development of effective, culturally relevant risk reduction programs.

    Skoog, D.A.; West, D.M.; Holler, F.J.

    1988-01-01

    Fundamentals of Analytical Chemistry is divided into three roughly equal parts. The first 14 chapters cover classical methods of analysis, including titrimetry and gravimetry as well as solution equilibria and statistical analysis. The next 11 chapters address electroanalytical, optical, and chromatographic methods of analysis. The remainder of the text is devoted to discussions of sample manipulation and pretreatment, good laboratory practices, and detailed directions for performing examples of 17 different types of classical and instrumental analyses. Like its predecessors, this fifth edition provides comprehensive coverage of classical analytical methods and the major instrumental ones in a literary style that is clear, straightforward, and readable. New terms are carefully defined as they are introduced, and each term is italicized for emphasis and for ease of relocation by the student who may forget its meaning. The chapters on analyses of real-world samples, on avoiding interferences, and on techniques for sample preparation should prove especially useful for the practicing chemist

    Hoffman, Reviewed By Megan M.

    2000-01-01

    "You're going to teach the organic chemistry section of the Natural Science class?" - one of my biology colleagues asked me last semester - "Better you than me!" "You are?" added a chemistry professor, with interest. Yet these same people ardently believe that all our students should have a basic understanding of carbon's remarkable bonding capabilities and how they relate to life on Earth. If our art or economics majors can learn about organic chemistry and genetics and astronomy, our faculty should be able to teach those same topics, regardless of their acknowledged specialties. The basis of a scientifically literate society is not expertise in specific arcane subfields of science. Scientific literacy is a general understanding of what science is, what science can and cannot do, and what scientific accomplishments have occurred over the centuries. If you subscribe to this definition of scientific literacy, James Trefil and Robert M. Hazen's The Sciences: An Integrated Approach can help you and your general science students. The self-avowed purpose of this text is to address science illiteracy in America. Trefil and Hazen propose that the best way to combat scientific illiteracy is to provide integrated science courses that focus on a broad understanding of science, rather than the specialized knowledge available to a science major. The new edition of The Sciences has been influenced by the 1996 publication of the National Research Council's National Science Education Standards. While the first edition of Trefil and Hazen's book admirably addressed the integration of the natural and physical sciences, in this second edition, the authors have increased the connections between science and real-world situations and have made a more conscious effort to emphasize the process of science and the overlapping nature of scientific disciplines. The text is based on 25 "scientific concepts", one per chapter. These concepts are clearly explained in relatively jargon

    Three-dimensional imaging of complex structures relies heavily on the ability to edit the routine CT scans to provide an optimal view of the area in question. The authors present a series of strategies for defining the volume editing tools. The authors have developed a series of editing tools that allow the operator to edit critical areas out of an image. The tools are based on a variety of imaging strategies that are implemented depending on the difficulty of separating two structures. The tools combine rectangular masking, threshold base filling, arbitrary curve-based masking, masking, threshold base filling, arbitrary curve-based masking, and object definition via edge detection

    University and college campuses may be the last setting where it is possible to comprehensively address the health of a large proportion of the young adult population. It is important that health promoters understand the collective challenges students are facing, and to better understand the broader lifestyle behavioural patterning evident during this life stage. The purpose of this study was to examine the clustering of modifiable health-risk behaviours and to explore the relationship between these identified clusters and mental health outcomes among a large Canadian university sample. Undergraduate students (n = 837; mean age = 21 years) from the University of Toronto completed the National College Health Assessment survey. The survey consists of approximately 300 items, including assessments of student health status, mental health and health-risk behaviours. Latent class analysis was used to identify patterning based on eight salient health-risk behaviours (marijuana use, other illicit drug use, risky sex, smoking, binge drinking, poor diet, physical inactivity, and insufficient sleep). A three-class model based on student behavioural patterns emerged: "typical," "high-risk" and "moderately healthy." Results also found high-risk students reporting significantly higher levels of stress than typical students (χ2(1671) = 7.26, p Students with the highest likelihood of engaging in multiple health-risk behaviours reported poorer mental health, particularly as it relates to stress. Although these findings should be interpreted with caution due to the 28% response rate, they do suggest that interventions targeting specific student groups with similar patterning of multiple health-risk behaviours may be needed.

    Full Text Available Genome editing and human induced pluripotent stem cells hold great promise for the development of isogenic disease models and the correction of disease-associated mutations for isogenic tissue therapy. CRISPR-Cas9 has emerged as a versatile and simple tool for engineering human cells for such purposes. However, the current protocols to derive genome-edited lines require the screening of a great number of clones to obtain one free of random integration or on-locus non-homologous end joining (NHEJ-containing alleles. Here, we describe an efficient method to derive biallelic genome-edited populations by the use of fluorescent markers. We call this technique FACS-assisted CRISPR-Cas9 editing (FACE. FACE allows the derivation of correctly edited polyclones carrying a positive selection fluorescent module and the exclusion of non-edited, random integrations and on-target allele NHEJ-containing cells. We derived a set of isogenic lines containing Parkinson's-disease-associated mutations in α-synuclein and present their comparative phenotypes.

    Alcohol consumption in our society is a known, and a widely discussed problem, due to the proven negative impact of excessive usage of spirits on health. Aim of the study was to evaluate the rate of consumption, and risk of an alcoholic disease among Polish students. Study was carried out using an authors' own questionnaire, made of a queries about amount and frequency of alcohol consumption, risky behaviors and knowledge about alcoholism. Research was conducted through community portals (f.e. facebook.com), and within 3 weeks time (from a 10(th) of January to 31(st) of January 2013) 1300 students from different Polish universities participated in it. Out of them, after removal of inadequate questionnaires, group of 1259 students (822 females, 437 males) was selected for further analysis. Average age equaled to 21.5, with the maximum of 27 and minimum of 18 years. For the statistical analysis StatSoft "Statistica" 10.0 software was used. The study shows that 95.5% of students use alcohol (mostly beer and vodka) and they tend to overuse it. 28.86% of respondents drank excessively more than 3 times during the month preceding research, 46% of subjects also had an alcoholic palimpsest more than once, 12.7% need an alcohol to enjoy a party and 0.83% of respondents can't control the amount of a one-time alcohol consumption. 3.32% of students may be in the group of a high alcoholism risk. Alcohol consumption is a common problem among Polish students. Most of respondents, mostly males, drink excessively and potentially risky for their health. There is a remarkable group of students endangered with alcohol addiction.

    Full Text Available Background: Metabolic syndrome is highly prevalent in the adult population worldwide. Education may play an important role in preventing metabolic syndrome in young adults, especially those who are attending university. Such adults are at a critical point in their lives and make their own lifestyle choices that can affect their future health. Aims: The aims of this study were to determine the metabolic syndrome risk levels of students from the Faculty of Health Sciences. Study Design: Survey design study. Methods: In a questionnaire developed by the researchers to collect data in accordance with the relevant literature, the scale of the risk of metabolic syndrome was assessed. A stepwise logistic regression analysis was performed to determine the risks. Results: Important risk factors for metabolic syndrome were found to be gender, weight gain, “stress eating” excessive amounts of food, sleeping for more than 8 hours a day, feeling tired after sleep, belonging to a divided family, and eating whilst working on the computer. Conclusion: The students from the Faculty of Health Sciences, particularly because they are trained in the health sector, are expected to have more information about the risk factors of metabolic syndrome, and take necessary precautions to prevent it.

    Full Text Available Fan edits assert that fan authority is on par with that of a work's original creator; this authority is generated not only through the argument, but through the structure of the text itself. Fan edits adhere to classical filmmaking techniques, creating coherent plots and editing for continuity. These recut texts are emblematic of current ownership debates; they are the read/write culture brought to fandom. The Star Wars series of films are among the most frequently recut texts and are my focus here.

    This study aimed to clarify relationships between prevalence of risk behaviors and sleep duration among Japanese high school students. Data from a national survey, the Japan Youth Risk Behavior Survey 2011 (the subjects were 9,778 students: 5,027 males, 4,751 females, in the first grade to the third grade of 102 schools randomly selected among high schools throughout Japan) was used for this analysis. We focused on nine items of risk behavior in JYRBS: "lack of vigorous physical activity," "skipping breakfast," "current cigarette use," "current alcohol use," "lifetime thinner use," "ever had sexual intercourse," "rarely or never wore seatbelts," "in a physical fight," and "seriously considered attempting suicide." Students with less than six hours of sleep duration accounted for approximately 40% of males and females. The odds ratios of prevalence of each of the nine risk behaviors were calculated on the basis of the group "six hours or more and less than eight hours" of sleep, whose prevalence of risk behaviors was the lowest. In the group with "four hours or more and less than six hours," the odds ratios of "lack of vigorous physical activity" and "skipping breakfast" for both males and females were significantly high. Furthermore, in the group with shorter sleep duration of "less than four hours," the odds ratios of all nine risk behaviors for males (odds ratios: 1.47-3.28) and eight risk behaviors (except for "rarely or never wore seatbelts") for females (1.54-4.68) were significantly high. On the other hand, in the group with long sleep duration of "10 hours or more," the odds ratios of "current cigarette use" and "lifetime thinner use" for both males and females were significantly high. It was shown that short sleep duration of less than six hours and long sleep duration of 10 hours or more related to the prevalence of youth risk behaviors among Japanese high school students. It was suggested that sleep duration should be considered as an important category
