2015-02-01

Full Text Available The characteristically disruptive conduct exhibited both at school and home by children diagnosed with attention deficit hyperactivity disorder (ADHD appears to be particularly emotionally difficult for the children's mothers, who often turn to educational professionals for guidance. With a view to improving best practice in assistance to mothers and to promoting the tenets of inclusive education policy, the authors investigated the ways in which mothers experienced the support provided by educational psychologists. A qualitative interpretivist approach was adopted, with five purposefully selected mothers, whose children had previously been diagnosed with ADHD. Data was gathered from a focus group discussion and an individual interview. It emerged that mothers experienced parenting their children with ADHD as stressful, requiring continual reassurance and emotional support from educational psychologists. Having need of counselling for their families and academic help for their children, these mothers expected that educational psychologists should collaborate with educators and other role players, so as to enhance overall support to their children as learners. The findings pointed to the need for an effective inclusive school environment that forefront the role of educational psychologists in sharing knowledge and working collaboratively across the education system in South Africa.

Bradley, Stacy; Drapeau, Martin; Destefano, Jack

2012-01-01

Continuing education is one of the means by which professionals maintain and increase their level of competence. However, the relationship between continuing education and the professional's sense of personal competence and other practice-related variables remains unclear. This study examined practicing psychologists' continuing education activities and how these relate to feelings of perceived competence, professional value, and professional support. Psychologists (n = 418) licensed to practice in Quebec were surveyed by pencil-and-paper mail-in survey concerning their continuing education activities, as well as their perceptions of their competence in practice, and their feelings of being professionally valued and professionally supported. Results indicated that feelings of competence in practice were related to professional reading, taking courses/workshops, years being licensed, and attending psychology conferences/conventions. Feelings of professional value were related to age and participating in psychology networking groups, and feelings of professional support were related to participating in case discussion groups, supervision groups, and psychology networking groups. The results showcase the complexity of professional development. Although relationships were found between continuing education activities and the 3 factors of interest, these relationships were moderate. Findings are discussed in the context of their value to individual psychologists, as well as to psychology licensing and regulatory boards, such as promoting participation in those activities related to feelings of competence and support.

Educational Psychologist Training for Special and Developmental Teaching as Professional Activity

Directory of Open Access Journals (Sweden)

Gavrilushkina O.P.

2015-11-01

Full Text Available The article presents the experience of designing the educational module "Special and Developmental Teaching" of School Psychology Master’s program. The modular-sized program includes practical training and research activity in each module in a networking, it complies with Federal State Educational Standard and professional teaching and educational psychology standarts. Practice-oriented education Master’s training model based on the activity and competence approaches is productive. We have shown the advantages of networking and the need to divert more resources towards practical training and to include research activity in particular module. It is necessary to teach educational psychologists not only to "know", but also to "knows how", to have professional thinking and metasubject competencies, to have the capacity for reflection, i. e. to operate in an uncertain environment for new schemes on the basis of the scientific method. It is important that the modular principle design allows adding training subjects from one of educational program to other and so developing new programs.

A psychologist-led educational intervention results in a sustained reduction in neonatal intensive care unit infections

Directory of Open Access Journals (Sweden)

Hans eVan Rostenberghe

2014-11-01

Full Text Available Even though in the corporate world psychological science has been widely used, the formal use of evidence- based psychology in important areas of clinical medicine has been scanty at best. It was the aim of this study to determine the efficacy of a psychologist-led two-week nurse educator training on the infection rate in the NICU. Materials and methods: Six senior neonatal nurses underwent in 2007 a training course covering the retrieval of evidence and knowledge of psychological principles that would allow them to share the evidence in such a way that evidence is effectively brought into practice. The course was led by a psychologist. The nurses created and delivered their own teaching modules, all focused on infection control. The rates of bacteraemia, 2 years prior to intervention were analyzed and compared with the rate following the intervention for three years.Results: The immediate output of the course included three teaching modules (hand washing, sterile procedures, general measures to control infection. These modules were subsequently administered to the NICU nurses in structured and regular continuous nursing education (CNE sessions. The psychological techniques taught in the course were applied. Bacteraemia in the NICU significantly decreased in the year of the course and the subsequent years when compared to previous years.Conclusion: This study suggests that a psychologist-led course, followed by a structured CNE can lead to a sustainable reduction in infection rates in a NICU.

To treat or not to treat: should psychologists treat tobacco use disorder?

Science.gov (United States)

Bodie, Linda P

2014-08-01

The author presented this Presidential Address for Divison 18, Psychologists in Public Service, at the 2012 American Psychological Association Convention in Orlando, Florida. The address challenges public service psychologists to reduce the tobacco disease burden through their roles as researchers, leaders, educators, and practitioners and explains why treating tobacco use disorder is important and relevant for psychologists. The address discusses the prevalence and the resulting mortality and morbidity rates of tobacco use disorder, which call for effective evidence-based interventions that can be integrated by psychologists into other ongoing treatments. Treatment of the underserved populations, including those with serious mental illness and/or substance use disorders, presents many barriers. In addition, education and training for tobacco use disorder in undergraduate and graduate clinical psychology programs present further barriers for psychology trainees. However, progress is being made because of the numerous resources and psychology leaders who are advocates for tobacco use disorder treatment and research. Challenges for the future include increasing awareness of the importance of treatment for tobacco use disorder, finding innovative ways to increase access to comprehensive evidence-based treatment, and acknowledging that psychologists can make a difference in reducing the tobacco use disorder disease burden. Psychologists have an ethical and professional responsibility to treat tobacco use disorder.

2014-10-01

Research purpose: The aim of this study was to review the role of I-O psychologists as counsellors and to ascertain whether these practitioners are effectively prepared for this purpose. Motivation for the study: I-O psychologists are mainly concerned with the deep-rooted problems individuals experience in the workplace, and they therefore need appropriate counselling skills. However, it is not clear whether graduates in this discipline receive adequate training for this role. Research design, approach and method: A qualitative research design with convenience and snowball sampling of 22 participants was utilised. Participants were practising I-O psychologists across Gauteng and North West (South Africa. Semi-structured in-depth interviews were used to gather data, which were transcribed verbatim and analysed using content analysis. Main findings: Participants were familiar with the meaning of counselling and confirmed that they are faced with a range of counselling situations requiring a unique set of skills and competencies. Based on these findings, participants made recommendations for the future training of I-O psychologists and recommended that counselling be included in the scope of practice of I-O psychologists. Practical/managerial implications: The role of the I-O psychologist requires training in short-term therapeutic techniques and counselling in tertiary education. Contribution/value-add: The study clarifies the role of the I-O psychologist as a counsellor that will ensure that I-O psychologists can be trained more effectively for this role.

LaPaglia, Donna; Thompson, Britta; Hafler, Janet; Chauvin, Sheila

2017-06-01

Psychologists' roles within academic medicine have expanded well beyond research and scholarship. They are active as providers of patient care, medical education, and clinical supervision. Although the number of psychologists in academic health centers continues to grow, they represent a small portion of total medical school faculties. However, with the movement toward collaborative care models, emphasis on interprofessional teams, and increased emphasis on psychological science topics in medical curricula, psychologists are well-positioned to make further contributions. Another path through which psychologists can further increase their contributions and value within academic health centers is to aspire to leadership roles. This article describes the first author's reflections on her experiences in a two-year, cohort-based, educational leadership development certificate program in academic medicine. The cohort was comprised largely of physicians and basic scientists, and a small number of non-physician participants of which the first author was the only clinical psychologist. The insights gained from this experience provide recommendations for psychologists interested in leadership opportunities in academic medicine.

A partial report from a study dealing with Psychology's current status in Argentina is presented. Pursuant to this preliminary study 36,128 psychologists have taken their degree at both State and private universities in Argentina--between 1956, when the first Department of Psychology was created, and 1992. So, over a 32.5-million population (as per the 1991 census), there is a psychologist every 897 inhabitants, or 111 psychologists every 100,000 inhabitants. According to psychologists' geographical distribution, the highest density is to be found in the capital city of Buenos Aires (one psychologist every 246 inhabitants) while the lowest density is to be found in the Province of Chaco (one psychologist every 17,465 inhabitants). During year 1993, a total of 26,726 students have been studying Psychology at the different Argentine universities: Of these, 6,858 have taken their Psychology degree during this academic year. A great majority of psychologists work in the clinical field, being Psychoanalysis their prominent theoretical orientation. Ladies psychologists supposedly account for 85% of the overall number of psychologists. Psychological Associations have 24,878 active psychologists recorded, of which a great majority work in the clinical field.

Older Driver Safety: A Survey of Psychologists' Attitudes, Knowledge, and Practices.

Science.gov (United States)

Love, Janet; Tuokko, Holly

2016-09-01

Using an online survey, we examined the knowledge, attitudes, and practices with respect to older driver safety concerns of clinical psychologists from across Canada who self-identified as working with at least some drivers over 60 years of age. Eighty-four psychologists completed the survey, and many were aware of the issues relevant to older driver safety, although only about half reported that assessing fitness to drive was an important issue in their practice. The majority (75%) reported that they would benefit from education concerning evaluation of fitness to drive. The primary recommendation emerging from this investigation is to increase efforts to inform and educate psychologists about driving-related assessment and regulatory issues in general, and specifically with respect to older adults. As the population ages, it is of growing importance for all health care providers to understand the influence of mental health conditions-including cognitive impairment and dementia-on driving skills.

Recognition of names of eminent psychologists.

Science.gov (United States)

Duncan, C P

1976-10-01

Faculty members, graduate students, undergraduate majors, and introductory psychology students checked those names they recognized in the list of 228 deceased psychologists, rated for eminence, provided by Annin, Boring, and Watson. Mean percentage recognition was less than 50% for the 128 American psychologists, and less than 25% for the 100 foreign psychologists, by the faculty subjects. The other three groups of subjects gave even lower recognition scores. Recognition was probably also influenced by recency; median year of death of the American psychologists was 1955, of the foreign psychologists, 1943. High recognition (defined as recognition by 80% or more of the faculty group) was achieved by only 34 psychologists, almost all of them American. These highly recognized psychologists also had high eminence ratings, but there was an equal number of psychologists with high eminence ratings that were poorly recognized.

Family planning providers' role in offering PrEP to women.

Science.gov (United States)

Seidman, Dominika; Weber, Shannon; Carlson, Kimberly; Witt, Jacki

2018-03-09

Pre-exposure prophylaxis (PrEP) provides a radically different HIV prevention option for women. Not only is PrEP the first discrete, woman-controlled method that is taken in advance of exposure, but it is both safe and highly effective, offering over 90% protection if taken daily. While multiple modalities of PrEP are in development ranging from vaginal rings to injectables and implants, only PrEP with oral tenofovir/emtricitabine is currently FDA-approved. Family planning clinics provide key access points for many women to learn about and obtain PrEP. By incorporating PrEP services into family planning care, family planning providers have the opportunity to meet women's expectations, ensure women are aware of and offered comprehensive HIV prevention options, and reverse emerging disparities in PrEP access. Despite real and perceived barriers to integrating PrEP into family planning care, providing PrEP services, ranging from education to onsite provision, is not only possible but an important component of providing high-quality sexual and reproductive healthcare to women. Lessons learned from early adopters will help guide those in family planning settings initiating or enhancing PrEP services. Copyright © 2018. Published by Elsevier Inc.

Ethical issues in the professional work of psychologists: state of affairs in Slovenia

Directory of Open Access Journals (Sweden)

Tina Zupan

2000-12-01

Full Text Available The aim of the research was to determine the state of affairs regarding professional ethics of Slovene psychologists, particularly regarding the implementation of ethical principles and psychologists' and students' knowledge of ethics and procedures in the cases of ethical dilemmas and violations. Two dedicated questionnaires were designed by the authors. 800 Slovene psychologists received the questionnaire and 150 of them responded. There were also 56 psychology students involved in the study. The results show some problematic issues such as: record keeping, exceptions of confidentiality, access to personal data, the content of informed consent, incompetence, copying of literature and diagnostic instruments – even not standardised ones, psychology students as subjects in psychological research, and lack of information on ethical aspects of students' practical work. Psychologists and students reported inadequate knowledge of professional ethics and suggested various kinds of ethical education. Institutions mostly enable psychologists to work within the Code of ethics. There are, however, conflicts regarding access to data and professional autonomy. Psychologists report conflicts between law and ethics, incorrect reports in media and lack of control over professional ethics. In the case of ethical violation psychologists do less than they should. They emphasise the problem of incompetence. The frequency and seriousness of certain violation were estimated. Ways of verifying knowledge, stimulating ethical conduct and taking different measures in the case of violations were suggested. The state of affairs in different working environments of psychologists was also described. Results show that psychologist who have worked in the field for a shorter period answer more frequently contrary to the Code of Ethics. Students' knowledge of ethics is mostly very satisfactory. The study emphasises the ethical aspects of psychological practice in Slovenia. It

To examine trends in the psychologist workforce and training opportunities, including factors that may influence the decision of clinical psychologists to practice in rural settings. We use a mixed-methods approach to examine the psychologist workforce nationally and in North Carolina (NC), including (1) an analysis of the location of programs awarding doctoral degrees; (2) an analysis of the practice, demographic, and educational characteristics of the psychologist workforce; and (3) interviews with directors of doctoral programs in clinical psychology to understand where current graduates are getting jobs and why they may or may not be choosing to practice in rural communities. Fewer than 1% of programs and institutions awarding doctoral degrees in psychology in the United States are located in rural areas. In NC, approximately 80% of practicing psychologists have out-of-state degrees and about 80% of recent NC graduates are not currently licensed in the state. This juxtaposition undermines the utility of adding more in-state degree programs. While expansion of training programs within rural areas could help alleviate the shortages of mental health providers, adding new degree-granting programs alone will not necessarily increase supply. We discuss complementary recruitment and retention strategies, including greater incentives for rural training and practice as well as training in emerging technologies that don't require providers to be physically located in underserved areas, such as telemedicine. Increasing the supply of psychologists practicing in rural areas will require a thoughtful, multipronged approach to training this critical part of the behavioral health workforce. © 2018 National Rural Health Association.

Full Text Available In this article the analysis of professional standards in terms of the scope of work of the psychologist with clients in difficult life and legal situations. The criteria of analysis chosen: reflected in professional activities, the choice of grounds for the selection of professional activities that focus on a specific Department, selection of a particular direction of activity of the psychologist (prevention, support, rehabilitation. It is shown that all five of the analyzed standards imply such a situation, but only three of them ("educational psychologist", "Psychologist in the social sphere", "Specialist in rehabilitative work in the social sphere" describe the activities of the psychologist, and the remaining ("Expert of bodies of guardianship and guardianship concerning minors" and "Specialist in working with families" are more organizational in nature. The conclusion about compliance of the training programs developed by the Department of legal psychology and law and education, the requirements of professional standards, proposed improvements in these programs.

2017-08-01

This study aimed to evaluate questionnaire development to measure the knowledge of Complementary-Alternative Medicine (CAM), attitudes towards CAM, CAM experiences, and CAM educational needs of clinical psychologists in Indonesia. A 26-item questionnaire was developed through an extensive literature search. Data was obtained from provisional psychologists from the Master of Professional Clinical Psychology programs at two established public universities in urban areas of Indonesia. To validate the questionnaire, panel reviews by executive members of the Indonesian Clinical Psychology Association (ICPA), experts in health psychology, and experts in public health and CAM provided their professional judgements. The self-reporting questionnaire consisted of four scales including: knowledge of CAM (6 items), attitudes towards CAM (10 items), CAM experiences (4 items), and CAM educational needs (6 items). All scales, except CAM Experiences, were assessed on a 7-point Likert scale. Sixty provisional psychologists were eligible to complete the questionnaire with a response rate of 73% (N=44). The results showed that the CAM questionnaire was reliable (Cronbach's coefficient alpha range=0.62-0.96; item-total correlation range=0.14-0.92) and demonstrated content validity. Following further psychometric evaluation, the CAM questionnaire may provide the evidence-based information to inform the education and practice of Indonesian clinical psychologists.

Who Will Use Pre-Exposure Prophylaxis (PrEP) and Why?: Understanding PrEP Awareness and Acceptability amongst Men Who Have Sex with Men in the UK--A Mixed Methods Study.

Science.gov (United States)

Frankis, Jamie; Young, Ingrid; Flowers, Paul; McDaid, Lisa

2016-01-01

Recent clinical trials suggest that pre-exposure prophylaxis (PrEP) may reduce HIV transmission by up to 86% for men who have sex with men (MSM), whilst relatively high levels of PrEP acceptability have been reported to date. This study examines PrEP awareness amongst sub-groups of MSM communities and acceptability amongst MSM in a low prevalence region (Scotland, UK), using a mixed methods design. Quantitative surveys of n = 690 MSM recruited online via social and sociosexual media were analysed using descriptive statistics and multivariate logistic regression. In addition, n = 10 in-depth qualitative interviews with MSM were analysed thematically. Under one third (29.7%) of MSM had heard of PrEP, with awareness related to living in large cities, degree level education, commercial gay scene use and reporting an HIV test in the last year. Just under half of participants (47.8%) were likely to use PrEP if it were available but there was no relationship between PrEP acceptability and previous PrEP awareness. Younger men (18-25 years) and those who report higher risk UAI were significantly more likely to say they would use PrEP. Qualitative data described specific PrEP scenarios, illustrating how risk, patterns of sexual practice and social relationships could affect motivation for and nature of PrEP use. These findings suggest substantial interest PrEP amongst MSM reporting HIV risk behaviours in Scotland. Given the Proud results, there is a strong case to investigate PrEP implementation within the UK. However, it appears that disparities in awareness have already emerged along traditional indicators of inequality. Our research identifies the need for comprehensive support when PrEP is introduced, including a key online component, to ensure equity of awareness across diverse MSM communities (e.g. by geography, education, gay scene use and HIV proximity), as well as to responding to the diverse informational and sexual health needs of all MSM communities.

More than 40 years ago, psychologist-historian Robert Watson argued that the study of history was of particular salience to psychology. In this article we explore the relationship between psychology and history and argue that the psychologist-historian plays a vital role in the discipline of psychology. We provide a brief overview of the emergence of the history of psychology as a professional subdiscipline, describe who psychologist-historians are, explain why they are needed, and detail how to join their ranks. We argue that increasing historical sophistication among psychologists will have beneficial effects on research and teaching, and we invite all psychologists to participate in the making of psychology's history.

George Kelly: cognitive psychologist, humanistic psychologist, or something else entirely?

Science.gov (United States)

Benjafield, John G

2008-11-01

George Kelly was regarded by some of his contemporaries as a cognitive psychologist and by others as a humanistic psychologist. Kelly himself resisted being rubricized. He did, however, name several people who had been influential in his life and work, one of whom was J.F. Herbart. A comparison of Herbart and Kelly reveals several similarities. Both shared a belief that psychology was fundamentally a mathematical discipline. Both eliminated distinctions usually taken for granted in psychology, such as emotion versus cognition. Reconstructing Kelly's relation to Herbart allows one to see more clearly why Kelly was such a unique figure in 20th century psychology.

A Thematic Inquiry into the Burnout Experience of Australian Solo-Practicing Clinical Psychologists.

Science.gov (United States)

Hammond, Trent E; Crowther, Andrew; Drummond, Sally

2017-01-01

Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists' different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists' natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding 'first order constructs' and then axial code 'second order constructs.' Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients' expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of working as a solo

Vacuolar Localization of Endoproteinases EP(1) and EP(2) in Barley Mesophyll Cells.

Science.gov (United States)

Thayer, S S; Huffaker, R C

1984-05-01

The localization of two previously characterized endoproteinases (EP(1) and EP(2)) that comprise more than 95% of the protease activity in primary Hordeum vulgare L. var Numar leaves was determined. Intact vacuoles released from washed mesophyll protoplasts by gentle osmotic shock and increase in pH, were purified by flotation through a four-step Ficoll gradient. These vacuoles contained endoproteinases that rapidly degraded purified barley ribulose-1,5-bisphosphate carboxylase (RuBPCase) substrate. Breakdown products and extent of digestion of RuBPCase were determined using 12% polyacrylamide-sodium dodecyl sulfate gels. Coomassie brilliant blue- or silver-stained gels were scanned, and the peaks were integrated to provide quantitative information. The characteristics of the vacuolar endoproteinases (e.g. sensitivity to various inhibitors and activators, and the molecular weights of the breakdown products, i.e. peptide maps) closely resembled those of purified EP(1) and partially purified EP(2). It is therefore concluded that EP(1) and EP(2) are localized in the vacuoles of mesophyll cells.

Prescribing Privileges for Psychologists: A Public Service or Hazard?

Directory of Open Access Journals (Sweden)

Shaheen E. Lakhan

2007-07-01

Full Text Available The privilege to prescribe pharmacotherapeutics has been granted in limited areas to psychologists. The psychologist's role in society may be approaching a great evolution that can dramatically impact the state of mental healthcare and the discipline of psychiatry. Opponents argue drug company funding and cheaper non-PhD psychological professionals fuel the movement for prescription rights for PhD level psychologists. However, proponents claim that this right would equip psychologists with greater psychotherapeutic modalities and the capability of having richer doctor-patient relationships to diagnose and treat underserved populations. Nonetheless, the paucity of prescribing psychologist studies cannot allow the biopsychosocial community to make firm opinions, let alone a decision on this debate. This article reviews the history of clinical psychology and highlights the potential divergence into collaborative clinical and health psychologists and autonomous prescribing psychologists.

Pre-Exposure Prophylaxis: A Narrative Review of Provider Behavior and Interventions to Increase PrEP Implementation in Primary Care.

Science.gov (United States)

Silapaswan, Andrew; Krakower, Douglas; Mayer, Kenneth H

2017-02-01

Since FDA approval of HIV pre-exposure prophylaxis (PrEP) for HIV prevention, attention has been focused on PrEP implementation. The CDC estimates that 1.2 million U.S. adults might benefit from PrEP, but only a minority are using PrEP, so there is a significant unmet need to increase access for those at risk for HIV. Given the large numbers of individuals who have indications for PrEP, there are not enough practicing specialists to meet the growing need for providers trained in providing PrEP. Moreover, since PrEP is a preventive intervention for otherwise healthy individuals, primary care providers (PCPs) should be primary prescribers of PrEP. There are important clinical considerations that providers should take into account when planning to prescribe PrEP, which are highlighted in the clinical case discussed. A growing body of research also suggests that some providers may be cautious about prescribing PrEP because of concerns regarding its "real-world" effectiveness, anticipated unintended consequences associated with its use, and ambiguity as to who should prescribe it. This review summarizes findings from studies that have assessed prescriber behavior regarding provision of PrEP, and offers recommendations on how to optimize PrEP implementation in primary care settings. Development and dissemination of educational interventions for PCPs and potential PrEP users are needed, including improved methods to assist clinicians in identifying appropriate PrEP candidates, and programs to promote medication adherence and access to social and behavioral health services. PCPs are well-positioned to prescribe PrEP and coordinate health-related services to improve the sexual health of their patients, but tailored educational programs are needed.

We aimed to assess HIV pre-exposure prophylaxis (PrEP) awareness and prescribing practices among Washington State medical providers from diverse professional disciplines and practice types. In May 2016, we administered an anonymous online survey to licensed medical practitioners who provide primary, longitudinal, walk-in, emergency, obstetric, gynecologic, sexually transmitted infection (STI), or family planning care. Of 735 eligible providers, 64.8% had heard of PrEP. Younger providers and providers with a Doctor of Medicine (MD) degree were more likely to be aware of PrEP compared to older providers (p=0.0001) and providers of other training backgrounds (Advanced Registered Nurse Practitioner [ARNP], Doctor of Osteopathic Medicine [DO], or Physician Assistant [PA]) (p=0.04). Among providers aware of PrEP, most frequent reported concerns about prescribing were adherence (46.0%) and costs (42.9%). Providers felt very (20.1%) or somewhat (33.8%) comfortable discussing PrEP overall, but very (26.8%) or somewhat (44.7%) uncomfortable discussing cost and insurance issues. The 124 PrEP prescribers reported a median of 2 (range 1-175, total 1,142) patients prescribed PrEP. Prior authorizations and insurance denials had prevented prescriptions for 28.7% and 12.1% of prescribers, respectively. Interventions to improve PrEP access should include education to inform medical providers about PrEP, with particular attention to provider types less likely to be aware. Continued efforts to eliminate cost and insurance barriers and educate providers regarding financial resources would help improve PrEP access.

Differentiation of Students in the Early Danish Welfare State: Professional Entanglements Between Educational Psychologists and Psychiatrists

Directory of Open Access Journals (Sweden)

Christian Ydesen

2018-05-01

Full Text Available Historically, numerous contextual factors have influenced the practice of differentiating students. Scholars and practitioners consider it a context-sensitive practice subject to negotiations and entanglements among various agents, groups, interests, ideas, and values. Drawing on Foucault, this article pursues the practices, negotiations, and entanglements surrounding differentiation processes and IQ testing’s use in the early Danish welfare state. We argue that the differentiating practice of IQ testing in the Danish educational system resulted from various factors, including the increasing professionalisation of the educational system. This practice entailed an increased division of labour among professional groups; debates reflecting differing ideas about eugenics, heredity, and social equality; the schooling of psychologists and psychiatrists in Denmark; and the development of psychology and psychiatry as academic disciplines. In that sense, we will demonstrate that changes in society’s understanding of intelligence incorporating a greater use of environmental explanations can be said to reflect the emerging welfare society’s security mechanisms, and a willingness to cope with and address social inequality in an evolving and supposedly universalistic Danish welfare state.

Antiretroviral pre-exposure prophylaxis (PrEP) is recommended to prevent HIV infection among high-risk men who have sex with men (MSM) though not available in Brazil where the HIV epidemic persists unabated in this group. This cross-sectional study describes PrEP awareness and willingness and associated factors among MSM and transvestite/transgender women (trans women) pre-screened for the PrEP Brasil study. Awareness was reported by 61.3 % of the participants and was associated with age, education, site, study period and prior HIV testing. Most participants (82.1 %) were willing to use PrEP, which was associated with site, study period, number of male condomless anal sexual partners and anal sex with HIV positive/unknown partners. PrEP information is need among young and less educated individuals. Willingness to use PrEP was high and future studies should be conducted to confirm PrEP acceptability and the characteristics of the population who chose to adopt this intervention.

A Thematic Inquiry into the Burnout Experience of Australian Solo-Practicing Clinical Psychologists

Hammond, Trent E.; Crowther, Andrew; Drummond, Sally

2018-01-01

Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists’ different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists’ natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding ‘first order constructs’ and then axial code ‘second order constructs.’ Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients’ expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of

Balancing life and work by unbending gender: Early American women psychologists' struggles and contributions.

Science.gov (United States)

Johnston, Elizabeth; Johnson, Ann

2017-07-01

Women's participation in the work force shifted markedly throughout the twentieth century, from a low of 21 percent in 1900 to 59 percent in 1998. The influx of women into market work, particularly married women with children, put pressure on the ideology of domesticity: an ideal male worker in the outside market married to a woman taking care of children and home (Williams, 2000). Here, we examine some moments in the early-to-mid-twentieth century when female psychologists contested established norms of life-work balance premised on domesticity. In the 1920s, Ethel Puffer Howes, one of the first generation of American women psychologists studied by Scarborough and Furumoto (1987), challenged the waste of women's higher education represented by the denial of their interests outside of the confines of domesticity with pioneering applied research on communitarian solutions to life-work balance. Prominent second-generation psychologists, such as Leta Hollingworth, Lillian Gilbreth, and Florence Goodenough, sounded notes of dissent in a variety of forums in the interwar period. At mid-century, the exclusion of women psychologists from war work galvanized more organized efforts to address their status and life-work balance. Examination of the ensuing uneasy collaboration between psychologist and library scholar Alice Bryan and the influential male gatekeeper E. G. Boring documents gendered disparities in life-work balance and illuminates how the entrenched ideology of domesticity was sustained. We conclude with Jane Loevinger's mid-century challenge to domesticity and mother-blaming through her questioning of Boring's persistent focus on the need for job concentration in professional psychologists and development of a novel research focus on mothering. © 2017 Wiley Periodicals, Inc.

HIV-negative male couples' attitudes about pre-exposure prophylaxis (PrEP) and using PrEP with a sexual agreement.

Science.gov (United States)

Mitchell, Jason W; Lee, Ji-Young; Woodyatt, Cory; Bauermeister, José; Sullivan, Patrick; Stephenson, Rob

2016-08-01

One efficacious strategy to help prevent HIV is oral pre-exposure prophylaxis (PrEP), a daily regimen of antiretroviral treatment taken by HIV-negative individuals. Two of the recommendations of Centers for Disease Control and Prevention (CDC) guidelines for PrEP pertain to being in a relationship (i.e., male couples). Despite the recognition of how primary partners in male couples' relationships shape HIV risk and CDC's PrEP guidelines, there is a paucity of data that examine HIV-negative male couples' attitudes toward PrEP use and using PrEP with a sexual agreement. A sexual agreement is an explicit agreement made between two individuals about what sex and other related behaviors may occur within and outside of their relationship. In this qualitative study, we examine HIV-negative male couples' attitudes toward PrEP use and whether they thought PrEP could be integrated into a sexual agreement. Data for this study are drawn from couple-level interviews conducted in 2014 with 29 HIV-negative male couples who had a sexual agreement and were from Atlanta or Detroit. Both passive (e.g., flyers) and active (e.g., targeted Facebook advertisements) recruitment methods were used; the sample was stratified by agreement type. Thematic analysis was applied to identify the following themes regarding HIV-negative male couples' attitudes toward PrEP use: (1) PrEP and condom use; (2) concerns about PrEP (e.g., effectiveness, side effects, and promoting sexually risky behavior); and (3) accessibility of PrEP. Some thought PrEP could be a part of couples' agreement because it could help reduce sexual anxiety and sexual risk, and would help keep the couple safe. Others described PrEP use with an agreement as something for "others". Some were also concerned that incorporating PrEP could usurp the need for a sexual agreement in a couples' relationship. These themes highlight the need to improve informational messaging and promotion efforts about PrEP among HIV-negative male couples

Workplace Responses and Psychologists' Needs Following Client Suicide.

2017-01-01

This research aimed to explore the role of workplace responses in psychologists' adaptation to client suicides. Participants were 178 psychologists who completed an online self-report questionnaire which included both open and closed questions yielding qualitative and quantitative data. Fifty-six (31.5%) participants reported one or more client suicides. Mixed results were found in terms of perceived support from the workplace following a client suicide. Psychologists reported a need for more open communication in the workplace, peer supports, space to grieve, as well as opportunities to engage in a learning process. The findings have important implications for research and for understanding the role of the workplace postvention. It also raises the need for external support to be accessible for psychologists working in private practice.

PrEP Whores and HIV Prevention: The Queer Communication of HIV Pre-Exposure Prophylaxis (PrEP).

Science.gov (United States)

Spieldenner, Andrew

2016-12-01

HIV pre-exposure prophylaxis (PrEP) has been introduced as another biomedical tool in HIV prevention. Whereas other such tools-including post-exposure prophylaxis (PEP) and interruption of perinatal transmission-have been embraced by those impacted by HIV, PrEP has been met with more conflict, especially within the gay community and HIV organizations. The "PrEP whore" has come to designate the social value and personal practices of those taking PrEP. This study examines the "PrEP whore" discourse by using queer theory and quare theory. Within these theoretical vantage points, the study explicates four discursive areas: slut shaming, dirty/clean binaries, mourning the loss of condoms, and reclaiming the inner whore. The study illuminates possible discursive strategies that lie outside of the domains of public health and within the individual and community.

Growth profile and extracellular polymeric substances (EPS) production of Serratia sp.1 was studied in shake flask fermentation for 72 h using wastewater sludge as raw material. Maximum cell concentration of 6.7 × 10(9) cfu/mL was obtained at 48 h fermentation time. EPS dry weight, flocculation activity and dewaterability of different EPS (tightly bound or TB-EPS, loosely bound or LB-EPS and broth-EPS or B-EPS) were also measured. The highest concentration of LB-EPS (2.45 g/L) and TB-EPS (0.99 g/L) were attained at 48 h of fermentation. Maximum flocculation activity and dewaterability (ΔCST) of TB-EPS (76.4%, 14.5s and 76.5%, 15.5s), LB-EPS (67.8%, 8.1s and 64.7%, 7.6s) and broth EPS (61%, 6.1s and 70.4%, 6.8s) were obtained at 36 and 48 h of growth. Higher flocculation activity and dewaterability were achieved with TB-EPS than with the two other EPS. Characterization of TB-EPS and LB-EPS was done in terms of their protein and carbohydrate content. Protein content was much higher in TB-EPS where as carbohydrate content was only slightly higher in TB-EPS than LB-EPS. Morphology of the Serratia strain after fermentation in sludge and TSB was observed under a scanning electron microscope and the cell size was found to be bigger in the sludge medium than the TSB medium.

Role of the pharmacist in pre-exposure chemoprophylaxis (PrEP therapy for HIV prevention

Directory of Open Access Journals (Sweden)

Clauson KA

2009-03-01

Full Text Available With a global estimate of 2.5 million new infections of HIV occurring yearly, discovering novel methods to help stem the spread of the virus is critical. The use of antiretroviral chemoprophylaxis for preventing HIV after accidental or occupational exposure and in maternal to fetal transmission has become a widely accepted method to combat HIV. Based on this success, pre-exposure chemoprophylaxis (PrEP is being explored in at-risk patient populations such as injecting drug users, female sex workers and men who have sex with men. This off-label and unmonitored use has created a need for education and intervention by pharmacists and other healthcare professionals. Pharmacists should educate themselves on PrEP and be prepared to counsel patients about their means of obtaining it (e.g. borrowing or sharing medications and ordering from disreputable Internet pharmacies. They should also be proactive about medication therapy management in these patients due to clinically important drug interactions with PrEP medications. Only one trial exploring the safety and efficacy of tenofovir as PrEP has been completed thus far. However, five ongoing trials are in various stages and two additional studies are scheduled for the near future. Unfortunately, studies in this arena have met with many challenges that have threatened to derail progress. Ethical controversy surrounding post-trial care of participants who seroconvert during studies, as well as concerns over emerging viral resistance and logistical site problems, have already halted several PrEP trials. Information about these early trials has already filtered down to affected individuals who are experimenting with this unproven therapy as an “evening before pill”. The potential for PrEP is promising; however, more extensive trials are necessary to establish its safety and efficacy. Pharmacists are well-positioned to play a key role in helping patients make choices about PrEP, managing their therapy

Gamarel, Kristi E; Golub, Sarit A

2015-04-01

In the USA, men who have sex with men (MSM) in primary partnerships are at elevated risk for human immunodeficiency virus (HIV) infection. Pre-exposure prophylaxis (PrEP), a new biomedical prevention strategy, has potential to reduce HIV transmission. This study examined predictors of PrEP adoption intentions among HIV-negative MSM in primary partnerships. The sample included HIV-negative MSM (n = 164) who participated in an ongoing cross-sectional study with an in-person interview examining PrEP adoption intentions. Higher HIV risk perception, intimacy motivations for condomless sex, recent condomless anal sex with outside partners, education, and age were each independently associated with PrEP adoption intentions. In a multivariate model, only age, education, and intimacy motivations for condomless sex were significantly associated with PrEP adoption intentions. Intimacy motivations may play a central role in PrEP adoption for MSM couples. Incorporating relationship dynamics into biomedical strategies is a promising avenue for research and intervention.

The School Psychology and Perception of Education Professionals

Directory of Open Access Journals (Sweden)

Ana Carolina Gravena Vanalli

2011-12-01

Full Text Available This study aimed at verifying the education professionals' perception about the performance of school psychologists. To attain this goal, 24 education professionals were interviewed, being 19 educators and five school psychologists from 11 private and public schools of two cities of São Paulo state. Based on descriptions about the psychologists' performance found in the literature, it is possible to compare them to the school psychologists' performance and to the education professionals' perception. From the data obtained, it was verified that the participants had knowledge, even though in a general perspective, about the performance area and considered important the service of those professionals to the school as an institution. However, it was noticed the difference of perception between the performances reported by the psychologists and these professionals' performance described by the other education professionals interviewed, seeming to generate dissatisfaction and possible conflicts. Therefore, it is necessary that the psychologist attributions become clearer and widespread so their interventions could match educators' expectations, provide satisfying results and be more frequently included in school institutions.

The Pre-Exposure Prophylaxis-Stigma Paradox: Learning from Canada's First Wave of PrEP Users.

Grace, Daniel; Jollimore, Jody; MacPherson, Paul; Strang, Matthew J P; Tan, Darrell H S

2018-01-01

With the emergence of daily oral tenofovir disoproxil fumarate and emtricitabine-based pre-exposure prophylaxis (PrEP) use in Canada, questions have emerged concerning the impacts of this HIV prevention tool on gay men's social and sexual lives. We conducted small focus groups and individual qualitative interviews with 16 gay men in Toronto who were part of the 'first wave' of Canadian PrEP users. Participants were on PrEP for at least one year as part of a demonstration project (November 2014-June 2016). These participants accessed PrEP before regulatory approval by Health Canada in February 2016. The mean age of participants was 37.6 years (SD 11.02); 94% completed secondary education, and 69% were white. Sex-stigma emerged as a complex theme in men's accounts of PrEP use across three overlapping domains: (1) PrEP-related stigma, including discussions of concealment and stigma from friends, family, and sexual partners, (2) PrEP as a perceived tool for combating HIV-related stigma, where some men said that they no longer discussed HIV status with sexual partners, and (3) PrEP as illuminating structural stigma, where it was attributed to unmasking stigma related to sex and sexuality. For some participants, PrEP has allowed for liberating sex and a self-described return to normalcy-normal, exciting, pleasurable sex that was no longer reliant on condom use. Paradoxically, some men said that PrEP use both led them to experience stigmatizing reactions within their social and sexual networks, while also helping to remove stigma, shame, and fear related to HIV, sexuality, and sex with gay men living with HIV.

Conceptualisations of mental illness are not universally applicable, as culture shapes the expression, perceptions and treatment preferences thereof. By focusing on the perceptions of Hindu psychologists regarding mental illness, this study aimed to provide a deeper understanding of the impact that religious beliefs have on such conceptualisations. Semi-structured interviews were conducted with six Hindu psychologists around the Johannesburg area, South Africa. Responses were analysed using thematic content analysis. From the findings, it was evident that religion plays a critical role in the understanding and treatment of mental illness. Hindu beliefs around psychological disturbances were salient. Additionally, it was found that a tension existed between psychologists' awareness of the influential function of religion, particularly amongst collectivistic communities such as the Hindu community, and their occupational understandings and practices, which are deeply rooted in Western thought. Furthermore, it was suggested that the fear of stigma prevented Hindu clients from reaping the benefits of seeking help from culturally competent psychologists.

The ethical ideologies of psychologists (who provide health services) and physicians were compared using the Ethics Position Questionnaire. The findings reveal that psychologists tend to be less relativistic than physicians. Further, we explored the degree to which physicians and psychologists report being influenced by a variety of factors (e.g., family views) in their ethical decision making. Psychologists were more influenced by their code of ethics and less influenced by family views, religious background, and peer attitudes than were physicians. We argue that these differences reflect the varied professional cultures in which practitioners are trained and socialized.

This study investigated the acceptability of daily use of free oral pre-exposure prophylaxis (PrEP) and associated factors among transgender women sex workers in Shenyang, China, following a briefing on PrEP. A total of 183 HIV negative or sero-status unknown participants completed the cross-sectional survey. The prevalence of acceptability of daily use of free oral PrEP was 61.2%. Adjusting for education level and monthly income, variables on negative attitudes toward PrEP (i.e., having concerns about the side-effects of PrEP) [Adjusted odds ratios (AOR): 0.26], perceived subjective norms (i.e., perceiving support from male partners to take PrEP) (AOR: 2.08), and perceived behavioral control (e.g., perceiving complete control over using PrEP) (AOR: 2.10-16.72) were significantly associated with acceptability of daily use of free oral PrEP. In addition, experiencing violence during sex work, perceived risk of contracting HIV from clients and probable anxiety were also significant. Future PrEP promotion campaigns should consider these factors.

The role of psychologists in health care delivery.

Wahass, Saeed H

2005-05-01

Advances in the biomedical and the behavioral sciences have paved the way for the integration of medical practice towards the biopsychosocial approach. Therefore, dealing with health and illness overtakes looking for the presence or absence of the disease and infirmity (the biomedical paradigm) to the biopsychosocial paradigm in which health means a state of complete physical, psychological and social well-being. Psychology as a behavioral health discipline is the key to the biopsychosocial practice, and plays a major role in understanding the concept of health and illness. The clinical role of psychologists as health providers is diverse with the varying areas of care giving (primary, secondary and tertiary care) and a variety of subspecialties. Overall, psychologists assess, diagnose, and treat the psychological problems and the behavioral dysfunctions resulting from, or related to physical and mental health. In addition, they play a major role in the promotion of healthy behavior, preventing diseases and improving patients' quality of life. They perform their clinical roles according to rigorous ethical principles and code of conduct. This article describes and discusses the significant role of clinical health psychology in the provision of health care, following a biopsychosocial perspective of health and illness. Professional and educational issues have also been discussed.

Home-based pre-exposure prophylaxis (PrEP services for gay and bisexual men: An opportunity to address barriers to PrEP uptake and persistence.

Directory of Open Access Journals (Sweden)

Steven A John

Full Text Available Gay, bisexual, and other men who have sex with men (GBM are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906 would prefer to get PrEP-related care from a primary care provider (PCP compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i.e., HB-PrEP, defined to participants as conducting HIV/STI self-testing from home with PrEP prescription mailing after an initial in-person clinic visit. We examined the associations of demographics, sexual HIV transmission risk, concern about frequent medical checkups associated with PrEP, health care access, and PrEP intentions with preferences for healthcare provider type and HB-PrEP. Concern about frequent medical checkups were associated with preferring a PCP for PrEP-related care, but men who perceived a barrier to bringing up the topic of PrEP with a doctor preferred a specialist clinic or provider more than a PCP. HB-PrEP was more appealing for younger men and those engaged in sexual HIV transmission risk, suggesting HB-PrEP could help reach GBM most vulnerable to HIV and in need of PrEP. HB-PrEP expansion has potential to increase PrEP uptake and persistence among GBM, particularly for men with barriers to clinic-based care and higher intentions to initiate PrEP. Clinical guidelines regarding HB-PrEP are needed to expand its use.

Development of the nuclear weapons complex EP architecture

Murray, C.; Halbleib, L.

1996-07-01

The Nuclear Weapons Guidance Team is an interagency committee led by Earl Whiteman, DOE that chartered the generation of EP40100, Concurrent Qualification and its successor EP401099, Concurrent Engineering and Qualification. As this new philosophy of concurrent operations has evolved and as implementation has been initiated, conflicts and insufficiencies in the remaining Engineering Procedures (EPs) have become more apparent. At the Guidance Team meeting in November 1995, this issue was explored and several approaches were considered. It was concluded at this meeting, that a smaller set of interagency EPs described in a hierarchical system could provide the necessary interagency direction to support complex-wide implementation. This set consolidates many existing EP processes where consistency and commonality are critical to success of the extended enterprise. The Guidance Team subsequently chartered an interagency team to initiate development activity associated with the envisioned new EP set. This team had participation from seven Nuclear Weapons Complex (NWC) sites as well as DOE/AL and DP-14 (team members are acknowledged later in this report). Per the Guidance Team, this team, referred to as the Architecture Subcommittee, was to map out and define an EP Architecture for the interagency EPs, make recommendations regarding a more agile process for EP approval and suggest an aggressive timeline to develop the combined EPs. The Architecture Subcommittee was asked to brief their output at the February Guidance Team meeting. This SAND report documents the results of the Architecture Subcommittee`s recommendations.

2014-01-01

As part of the National HIV Behavioral Surveillance System among men who have sex with men (MSM) in Denver, Colorado, we assessed knowledge of pre-exposure prophylaxis (PrEP); willingness to use PrEP; and potential changes in risk behaviors among HIV-negative participants reporting sexual activity with a male partner in the preceding 12 months. We examined knowledge of PrEP before (2008) and after (2011) results of the iPrEx trial were available. Of the 425 participants in the 2008 sample, 91 (21 %) were aware of PrEP compared to 131 (28 %) of the 461 participants in the 2011 sample (adjusted prevalence ratio: 1.43, 95 % confidence interval: 1.18, 1.72). Despite the increase in 2011, few MSM in Denver were aware of PrEP. Educating high-risk MSM about the potential utility of PrEP as an adjunct to other effective prevention methods is needed when considering the addition of PrEP to the HIV prevention arsenal.

This qualitative study explored the acceptability of HIV pre-exposure prophylaxis (PrEP) among MSM in India, and identified facilitators and barriers to future PrEP uptake. In 2014, we conducted 10 focus groups (n=61) among a purposive sample of diverse MSM recruited through community-based organizations in Chennai and Mumbai, and 10 key informant interviews with community leaders and health care providers. Participants' mean age was 26.1 years (SD 4.8); 62% completed secondary education, and 42% engaged in sex work. No focus group participants had heard of PrEP, but once explained, most reported they would likely use it. PrEP was alternately perceived as a 'back-up plan', a condom substitute, or a burden with concurrent condom use. Facilitators were potential for covert use, sex without condoms, and anxiety-less sex. Potential barriers emerged around stigma associated with PrEP use, fear of disclosures to one's family, wife, or male steady partner, and being labeled as HIV-positive or promiscuous by peers. Preferences emerged for intermittent rather than daily PrEP use, injectable PrEP, and free or subsidized access through community organizations or government hospitals. Key informants expressed additional concerns about risk compensation, non-adherence, and impact on ART availability for treatment. Demonstration projects are needed in India to support PrEP implementation tailored for at-risk MSM. Educational interventions for MSM should address concerns about PrEP effectiveness, side effects, and mitigate risk compensation. Community engagement may facilitate broad acceptability and challenge stigma around PrEP use. Importantly, provision of free or subsidized PrEP is necessary to making implementation feasible among low socioeconomic status MSM in India.

2017-01-01

Full Text Available The Serbian school system is currently undergoing a transformation process, dealing with important issues of interest to society as a whole. One of the possible directions of this transformation is the development of a positive school as an institution in which value is placed not only on achievement but also on the wellbeing of all parties. This paper considers to what extent the professional potential of school psychologists could be utilized in this process. The analysis presented here aims to reassess the possibilities of applying the principles of positive psychology to defining and implementing the role of school psychologists, and to put forward along these lines certain suggestions for their practical work. For this purpose, we have reviewed the theoretical foundations of positive education and related research findings, analysed regulations and research findings regarding the work of school psychologists in Serbian schools, and discussed prospects for their further engagement from the standpoint of contemporary theories of organizational changes and development. The possibilities for creating a positive school have been corroborated through numerous studies. According to Serbian school regulations, the school psychologist is expected to be engaged in improving all aspects of work in a school, as well as relationships between all participants in that process. Research findings on building a positive school provide a stimulus, while the position of the school psychologist provides the basis for his or her engagement in the process of transforming Serbian schools into positive schools. The conclusion is that school psychologists could contribute to the development of the school as a positive institution provided their professional role is redefined in accordance with the principles of positive psychology.

Recent clinical trials have shown that a daily dose of oral TDF/FTC pre-exposure prophylaxis (PrEP) is effective in reducing human immunodeficiency (HIV) risk. Understanding trial participants' perspectives about retention and PrEP adherence is critical to inform future PrEP trials and the scale-up and implementation of PrEP programs. We analyzed 53 in-depth interviews conducted in April 2010 with participants in the TDF2 study, a Phase 3, randomized, double-blind, placebo-controlled clinical trial of daily oral TDF/FTC with heterosexual men and women in Francistown and Gaborone, Botswana. We examined participants' knowledge, attitudes, and experiences of the trial, identified facilitators and barriers to enrollment and retention, and compared participant responses by study site, sex, and study drug adherence. Our findings point to several factors to consider for participant retention and adherence in PrEP trials and programs, including conducting pre-enrollment education and myth reduction counseling, providing accurate estimates of participant obligations and side effect symptoms, ensuring participant understanding of the effects of non-adherence, gauging personal commitment and interest in study outcomes, and developing a strong external social support network for participants.

Squires, Garry; Bragg, Joanna; Muscutt, Janet; Wasilewski, David

2014-01-01

There is growing concern internationally about the prevalence of mental health problems among school-aged children and their access to specialist services. School psychologists (SPs) may be one group of professionals well-positioned to support the well-being of children and young people, due to their position as applied psychologists working within educational settings and their capability to deliver therapeutic interventions. This research considers findings from a large scale, United Kingdom (UK)-wide survey of the views of SPs (N = 455) about facilitators and barriers to the provision of therapeutic interventions to children and young people. Principal Components Analyses of ranked questionnaire responses yielded three components: The role of the SP; training and practice; and support and psychology service context. Quantitative findings were then triangulated, using qualitative responses from the survey. Greater direction and clarification of the role of the SP as a provider of therapeutic interventions is recommended, particularly given the diverse roles undertaken by SPs and competing demands, particularly from assessment activities.

2011-01-01

In this research, piezoelectric ceramic PMN(lead magnesium niobate-lead zirconate-lead titanate)/carbon nano-fibers(CNFs)/epoxy resin(EP) ccomposites were prepared and the dynamic mechanical properties and damping mechanism of PMN/CNFs/EP composites were investigated. The addition of CNFs into PMN/EP composite results in decrease of volume resistivity of the composite. When the concentration of CNFs is 0.6% weight of epoxy resin the volume resistivity of PMN/CNFs/EP composite is about 10 8 Ω·m. Dynamic mechanical analysis indicates that the loss factor, loss area, and damping temperature range of PMN/CNFs/EP composites increase with the CNFs content increasing till to 0.6% of weight of epoxy resin. When the CNFs content is more than 0.6% the damping properties of composites decrease oppositely. In PMN/CNFs/EP composites, the CNFs content 0.6% and the volume resistivity of PMN/CNFs/EP composites about 10 8 Ω·m just satisfy the practicing condition of piezo-damping, so the composites show optimal damping property.

Research purpose: The aim of this study was to explore the personal and professional impact of including positive psychology in the professional training of clinical and counselling psychologists. Motivation for the study: It is not known how students previously educated in a pathogenic paradigm experience the exposure to positive psychology, and resultant paradigm shift, as part of their professional training. Research design, approach and method: A qualitative research design was implemented. Data consisted of written documents submitted by the participants and was analyzed by means of thematic analysis. Main findings: Integrating positive psychology in the professional training curriculum was valuable and enriching on both a professional and personal level. The participants reported an experience of positive emotions and increased sense of self-understanding and psychological well-being. Professionally they experienced a sense of increased self-efficacy. Practical/managerial implications: Positive psychology should be considered as part of the basic training of psychologists since it may enhance the development of trainee psychologists’ professional self, enhance aspects of psychological well-being as well as prevent stress and burnout. Contribution/value-add: This is the first South African study to explore the impact of including positive psychology principles and interventions in professional training.

Selected engineering properties and applications of EPS geofoam

Science.gov (United States)

Elragi, Ahmed Fouad

Expanded polystyrene (EPS) geofoam is a lightweight material that has been used in engineering applications since at least the 1950s. Its density is about a hundredth of that of soil. It has good thermal insulation properties with stiffness and compression strength comparable to medium clay. It is utilized in reducing settlement below embankments, sound and vibration damping, reducing lateral pressure on substructures, reducing stresses on rigid buried conduits and related applications. This study starts with an overview on EPS geofoam. EPS manufacturing processes are described followed by a review of engineering properties found in previous research work done so far. Standards and design manuals applicable to EPS are presented. Selected EPS geofoam-engineering applications are discussed with examples. State-of-the-art of experimental work is done on different sizes of EPS specimens under different loading rates for better understanding of the behavior of the material. The effects of creep, sample size, strain rate and cyclic loading on the stress strain response are studied. Equations for the initial modulus and the strength of the material under compression for different strain rates are presented. The initial modulus and Poisson's ratio are discussed in detail. Sample size effect on creep behavior is examined. Three EPS projects are shown in this study. The creep behavior of the largest EPS geofoam embankment fill is shown. Results from laboratory tests, mathematical modeling and field records are compared to each other. Field records of a geofoam-stabilized slope are compared to finite difference analysis results. Lateral stress reduction on an EPS backfill retaining structure is analyzed. The study ends with a discussion on two promising properties of EPS geofoam. These are the damping ability and the compressibility of this material. Finite element analysis, finite difference analysis and lab results are included in this discussion. The discussion with the

"Enhanced" interrogation of detainees: do psychologists and psychiatrists participate?

Halpern, Abraham L; Halpern, John H; Doherty, Sean B

2008-09-25

After revelations of participation by psychiatrists and psychologists in interrogation of prisoners at Guantánamo Bay and Central Intelligence Agency secret detention centers, the American Psychiatric Association and the American Psychological Association adopted Position Statements absolutely prohibiting their members from participating in torture under any and all circumstances, and, to a limited degree, forbidding involvement in interrogations. Some interrogations utilize very aggressive techniques determined to be torture by many nations and organizations throughout the world. This paper explains why psychiatrists and psychologists involved in coercive interrogations violate the Geneva Conventions and the laws of the United States. Whether done with ignorance of professional ethical obligations or not, these psychiatrists and psychologists have crossed an ethical barrier that may best be averted from re-occurring by teaching medical students and residents in all medical specialties about the ethics principles stemming from the 1946-1947 Nuremberg trials and the Geneva Conventions, together with the Ethics Codes of the World Medical Association and the American Medical Association; and, with regard to psychiatric residents and psychological trainees, by the teaching about The Principles of Medical Ethics With Annotations Especially Applicable to Psychiatry and the Ethical Principles of Psychologists and Code of Conduct, respectively. In this way, all physicians and psychologists will clearly understand that they have an absolute moral obligation to "First, do no harm" to the human beings they professionally encounter.

A maladaptive role for EP4 receptors in mouse mesangial cells.

Directory of Open Access Journals (Sweden)

Guang-xia Yang

Full Text Available Roles of the prostaglandin E2 E-prostanoid 4 receptor (EP4 on extracellular matrix (ECM accumulation induced by TGF-β1 in mouse glomerular mesangial cells (GMCs remain unknown. Previously, we have identified that TGF-β1 stimulates the expression of FN and Col I in mouse GMCs. Here we asked whether stimulation of EP4 receptors would exacerbate renal fibrosis associated with enhanced glomerular ECM accumulation. We generated EP4(Flox/Flox and EP4(+/- mice, cultured primary WT, EP4(Flox/Flox and EP4(+/- GMCs, AD-EP4 transfected WT GMCs (EP4 overexpression and AD-Cre transfected EP4(Flox/Flox GMCs (EP4 deleted. We found that TGF-β1-induced cAMP and PGE2 synthesis decreased in EP4 deleted GMCs and increased in EP4 overexpressed GMCs. Elevated EP4 expression in GMCs augmented the coupling of TGF-β1 to FN, Col I expression and COX2/PGE2 signaling, while TGF-β1 induced FN, Col I expression and COX2/PGE2 signaling were down-regulated in EP4 deficiency GMCs. 8 weeks after 5/6 nephrectomy (Nx, WT and EP4(+/- mice exhibited markedly increased accumulation of ECM compared with sham-operated controls. Albuminuria, blood urea nitrogen and creatinine (BUN and Cr concentrations were significantly increased in WT mice as compared to those of EP4(+/- mice. Urine osmotic pressure was dramatically decreased after 5/6 Nx surgery in WT mice as compared to EP4(+/- mice. The pathological changes in kidney of EP4(+/- mice was markedly alleviated compared with WT mice. Immunohistochemical analysis showed significant reductions of Col I and FN in the kidney of EP4(+/- mice compared with WT mice. Collectively, this investigation established EP4 as a potent mediator of the pro-TGF-β1 activities elicited by COX2/PGE2 in mice GMCs. Our findings suggested that prostaglandin E2, acting via EP4 receptors contributed to accumulation of ECM in GMCs and promoted renal fibrosis.

Thus, they affect the professionals’ decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italians, 30 Chileans, questioned on this topic. Our findings are consistent with original research and suggest that some participants do not know how to correctly interpret p values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researchers. Recommendations for improving statistical cognition are proposed.

The current study evaluates a depression prevention program for adolescents led by psychologists vs. teachers in comparison to a control. The universal school-based prevention program has shown its efficacy in several studies when implemented by psychologists. The current study compares the effects of the program as implemented by teachers versus that implemented by psychologists under real-life conditions. A total of 646 vocational track 8th grade students from Germany participated either in a universal prevention program, led by teachers (n = 207) or psychologists (n = 213), or a teaching-as-usual control condition (n = 226). The design includes baseline, post-intervention, and follow-up (at 6 and 12 months post-intervention). The cognitive-behavioral program includes 10 sessions held in a regular school setting in same-gender groups and is based on the social information-processing model of social competence. Positive intervention effects were found on the change in girls’ depressive symptoms up to 12 months after program delivery when the program was implemented by psychologists. No such effects were found on boys or when program was delivered by teachers. The prevention program can successfully be implemented for girls by psychologists. Further research is needed for explanations of these effects. PMID:24837667

Wastewater treatment plants often face the problems of sludge settling mainly due to sludge bulking. Generally, synthetic organic polymer and/or inorganic coagulants (ferric chloride, alum and quick lime) are used for sludge settling. These chemicals are very expensive and further pollute the environment. Whereas, the bioflocculants are environment friendly and may be used to flocculate the sludge. Extracellular polymeric substances (EPS) produced by sludge microorganisms play a definite role in sludge flocculation. In this study, 25 EPS producing strains were isolated from municipal wastewater treatment plant. Microorganisms were selected based on EPS production properties on solid agar medium. Three types of EPS (slime, capsular and bacterial broth mixture of both slime and capsular) were harvested and their characteristics were studied. EPS concentration (dry weight), viscosity and their charge (using a Zetaphoremeter) were also measured. Bioflocculability of obtained EPS was evaluated by measuring the kaolin clay flocculation activity. Six bacterial strains (BS2, BS8, BS9, BS11, BS15 and BS25) were selected based on the kaolin clay flocculation. The slime EPS was better for bioflocculation than capsular EPS and bacterial broth. Therefore, extracted slime EPS (partially purified) from six bacterial strains was studied in terms of sludge settling [sludge volume index (SVI)] and dewatering [capillary suction time (CST)]. Biopolymers produced by individual strains substantially improved dewaterability. The extracted slime EPS from six different strains were partially characterized. Copyright (c) 2009 Elsevier Ltd.

Halpern John H

2008-09-01

Full Text Available Abstract After revelations of participation by psychiatrists and psychologists in interrogation of prisoners at Guantánamo Bay and Central Intelligence Agency secret detention centers, the American Psychiatric Association and the American Psychological Association adopted Position Statements absolutely prohibiting their members from participating in torture under any and all circumstances, and, to a limited degree, forbidding involvement in interrogations. Some interrogations utilize very aggressive techniques determined to be torture by many nations and organizations throughout the world. This paper explains why psychiatrists and psychologists involved in coercive interrogations violate the Geneva Conventions and the laws of the United States. Whether done with ignorance of professional ethical obligations or not, these psychiatrists and psychologists have crossed an ethical barrier that may best be averted from re-occurring by teaching medical students and residents in all medical specialties about the ethics principles stemming from the 1946–1947 Nuremberg trials and the Geneva Conventions, together with the Ethics Codes of the World Medical Association and the American Medical Association; and, with regard to psychiatric residents and psychological trainees, by the teaching about The Principles of Medical Ethics With Annotations Especially Applicable to Psychiatry and the Ethical Principles of Psychologists and Code of Conduct, respectively. In this way, all physicians and psychologists will clearly understand that they have an absolute moral obligation to "First, do no harm" to the human beings they professionally encounter.

Background and Purpose The guinea pig trachea (GPT) is commonly used in airway pharmacology. The aim of this study was to define the expression and function of EP receptors for PGE2 in GPT as there has been ambiguity concerning their role. Experimental Approach Expression of mRNA for EP receptors and key enzymes in the PGE2 pathway were assessed by real-time PCR using species-specific primers. Functional studies of GPT were performed in tissue organ baths. Key Results Expression of mRNA for the four EP receptors was found in airway smooth muscle. PGE2 displayed a bell-shaped concentration–response curve, where the initial contraction was inhibited by the EP1 receptor antagonist ONO-8130 and the subsequent relaxation by the EP2 receptor antagonist PF-04418948. Neither EP3 (ONO-AE5-599) nor EP4 (ONO-AE3-208) selective receptor antagonists affected the response to PGE2. Expression of COX-2 was greater than COX-1 in GPT, and the spontaneous tone was most effectively abolished by selective COX-2 inhibitors. Furthermore, ONO-8130 and a specific PGE2 antibody eliminated the spontaneous tone, whereas the EP2 antagonist PF-04418948 increased it. Antagonists of other prostanoid receptors had no effect on basal tension. The relaxant EP2 response to PGE2 was maintained after long-term culture, whereas the contractile EP1 response showed homologous desensitization to PGE2, which was prevented by COX-inhibitors. Conclusions and Implications Endogenous PGE2, synthesized predominantly by COX-2, maintains the spontaneous tone of GPT by a balance between contractile EP1 receptors and relaxant EP2 receptors. The model may be used to study interactions between EP receptors. PMID:22934927

Drago Žagar

2011-12-01

Full Text Available In the paper the development of educational psychology as a scientific discipline is presented, and the history of its development in Slovenia is described in detail. The key scientific research and professional areas of educational psychologists are outlined. The fact is that the educational psychology in the broader Euro-American psychological context has a relatively longer tradition than in Slovenia. However, the analysis of various sources shows that the Slovene educational psychologists with their contributions have established a strong position in the modern international flows, both in the areas of educational psychological issues as well as in the methodology of the research. Nowadays Slovene educational psychologists with their research results, teaching and professional work offer an important contribution to the understanding, quality and the development of educational practice.

Pope, Kenneth S

2011-01-01

After the 9-11 terrorist attacks, U.S. psychologists faced hard choices about what roles, if any, were appropriate for psychologists in the detainee interrogations conducted in settings such as the Bagram Airbase, the Abu Ghraib Prison, and the Guantanamo Bay Detention Camps. The American Psychological Association (APA) sparked intense controversy with its policies and public statements. This article reviews APA decisions, documents, and public statements in this area, in the context of major criticisms and responses to those criticisms. The review focuses on key issues: how the APA created and reported policies in the areas of ethics and national security; transparency; psychologists' professional identities; psychologists' qualifications; ethical-legal conflicts; policies opposing torture; interpretations of avoiding harm; and effective interrogations. It suggests lessons learned, missed opportunities, and questions in need of a fresh approach. © 2011 by Annual Reviews. All rights reserved

2014-01-01

Background Mast cells play a critical role in allergic and inflammatory diseases, including exercise-induced bronchoconstriction (EIB) in asthma. The mechanism underlying EIB is probably related to increased airway fluid osmolarity that activates mast cells to the release inflammatory mediators. These mediators then act on bronchial smooth muscle to cause bronchoconstriction. In parallel, protective substances such as prostaglandin E2 (PGE2) are probably also released and could explain the refractory period observed in patients with EIB. Objective This study aimed to evaluate the protective effect of PGE2 on osmotically activated mast cells, as a model of exercise-induced bronchoconstriction. Methods We used LAD2, HMC-1, CD34-positive, and human lung mast cell lines. Cells underwent a mannitol challenge, and the effects of PGE2 and prostanoid receptor (EP) antagonists for EP1–4 were assayed on the activated mast cells. Beta-hexosaminidase release, protein phosphorylation, and calcium mobilization were assessed. Results Mannitol both induced mast cell degranulation and activated phosphatidyl inositide 3-kinase and mitogen-activated protein kinase (MAPK) pathways, thereby causing de novo eicosanoid and cytokine synthesis. The addition of PGE2 significantly reduced mannitol-induced degranulation through EP2 and EP4 receptors, as measured by beta-hexosaminidase release, and consequently calcium influx. Extracellular-signal-regulated kinase 1/2, c-Jun N-terminal kinase, and p38 phosphorylation were diminished when compared with mannitol activation alone. Conclusions Our data show a protective role for the PGE2 receptors EP2 and EP4 following osmotic changes, through the reduction of human mast cell activity caused by calcium influx impairment and MAP kinase inhibition.

Full Text Available Metastasis is the most dangerous risk faced by patients with hereditary non-polyposis colon cancer (HNPCC. The expression of matrix metalloproteinases (MMPs has been observed in several types of human cancers and regulates the efficacy of many therapies. Here, we show that treatment with various concentrations of prostaglandin E2 (PGE2; 0, 1, 5 or 10 μM promotes the migration ability of the human LoVo colon cancer cell line. As demonstrated by mRNA and protein expression analyses, EP2 and EP4 are the major PGE2 receptors expressed on the LoVo cell membrane. The Phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K/Akt cell survival pathway was upregulated by EP2 and EP4 activation. Following the activation of the PI3K/Akt pathway, β-catenin translocated into the nucleus and triggered COX2 transcription via LEF-1 and TCF-4 and its subsequent translation. COX2 expression correlated with the elevation in the migration ability of LoVo cells. The experimental evidence shows a possible mechanism by which PGE2 induces cancer cell migration and further suggests PGE2 to be a potential therapeutic target in colon cancer metastasis. On inhibition of PGE2, in order to determine the downstream pathway, the levels of PI3K/Akt pathway were suppressed and the β-catenin expression was also modulated. Inhibition of EP2 and EP4 shows that PGE2 induces protein expression of COX-2 through EP2 and EP4 receptors in LoVo colon cancer cells.

account the great current and future stakes of public health. It should be supplemented by psychopharmacology lectures. This reform of psychologists' training would ensure a common pedestal of increased knowledge coupled with theoretical/practical competence. The positive consequences of such a reform would relate to many fields. Here are six examples. Education: prevention, tracking, treatment of personal problems or of instruction from nursery school to university; orientation; council, assistance with managing difficulties of teaching staff, etc. Health: tracking, prevention, diagnosis, treatment of psychic and behavioural disorders, of addictive attitudes, of psychological problems related to somatic pathologies (cancer, HIV, etc.), of problems related to ageing of population; training and supervision of medical staff, etc. Justice: caring of victims, of offenders in prison or out of prison, fight against repetition, expertise, staff training (magistrates, lawyers, penitentiary staff, social workers...). Work context: (companies, public and private organisations): recruitment, management of staff problems, human resources management, coaching, competence assessment, orientation, etc. Sport: assessment, management and improvement of performances, management of stress, success, failures, and career; fight against doping; help for retraining after suspension of activity, etc. development of many useful research axes in relation to ground needs in all application fields of psychology. Such a reform, which would make it possible to shift towards a training more adapted to reality, more homogeneous and aiming at excellence, would ensure better guarantees of service to psychologist users and to their possible employers. Beyond a deep improvement of their initial training and their offer of competence, it would also enable psychologists to witness a very clear improvement of their professional status as well as their level of remuneration.

Of the two million new HIV infections in adults in 2014, 70% occurred in sub-Saharan Africa. Several African countries have already approved guidelines for pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV as part of combination HIV prevention but key questions remain about how to identify and deliver PrEP to those at greatest need. Throughout the continent, individuals in sero-discordant relationships, and members of key populations (sex workers, men who have sex with men (MSM), transgender women and injection drug users) are likely to benefit from the availability of PrEP. In addition, adolescent girls and young women (AGYW) are at substantial risk in some parts of the continent. It has been estimated that at least three million individuals in Africa are likely to be eligible for PrEP according to WHO's criteria. Tens of demonstration projects are planned or underway across the continent among a range of countries, populations and delivery settings. In each of the target populations, there are overarching issues related to (i) creating demand for PrEP, (ii) addressing supply-side issues and (iii) providing appropriate and tailored adherence support. Critical for creating demand for PrEP is the normalization of HIV prevention. Community-level interventions which engage opinion leaders as well as empowerment interventions for those at highest risk will be key. Critical to supply of PrEP is that services are accessible for all, including for stigmatized populations. Establishing accessible integrated services provides the opportunity to address other public health priorities including the unmet need for HIV testing, contraception and sexually transmitted infections treatment. National policies need to include minimum standards for training and quality assurance for PrEP implementation and to address supply chain issues. Adherence support needs to recognize that social and structural factors are likely to have an important influence

Politics and Israeli psychologists: is it time to take a stand?

Science.gov (United States)

Avissar, Nissim

2007-01-01

In Israel, it is quite rare for psychologists to relate to political and social issues. This remarkable tendency of psychologists to avoid dealing with such matters seems to supersede the common indifference or obtuseness of other groups in the Israeli public and similar groups in particular (e.g., physicians or social workers). Within this context, this paper focuses on the qualities and forms of reaction of the psychotherapeutic community in Israel to the national conflict that has been present intermittently since the late 1980s - namely, the two Intifadas. More specifically, as opposed to the current situation (the second Al-Aksa Intifada), in the course of the first Intifada (1987-1996), the voice of Israeli psychologists was clearly heard. Until now, this is the only exception to the rule of neutrality and passivity, in which psychologists in Israel became politically active. Specific elements of involvement of the therapeutic community is presented and discussed. Also, an attempt is made to suggest possible reasons to the very puzzling questions: Why then? Or what factors allowed for this change in position to occur? And more importantly, why did the protest of the psychologists in Israel vanish and their clear voices turn into silence?

Clinical Applications for EPs in the ICU.

Koenig, Matthew A; Kaplan, Peter W

In critically ill patients, evoked potential (EP) testing is an important tool for measuring neurologic function, signal transmission, and secondary processing of sensory information in real time. Evoked potential measures conduction along the peripheral and central sensory pathways with longer-latency potentials representing more complex thalamocortical and intracortical processing. In critically ill patients with limited neurologic exams, EP provides a window into brain function and the potential for recovery of consciousness. The most common EP modalities in clinical use in the intensive care unit include somatosensory evoked potentials, brainstem auditory EPs, and cortical event-related potentials. The primary indications for EP in critically ill patients are prognostication in anoxic-ischemic or traumatic coma, monitoring for neurologic improvement or decline, and confirmation of brain death. Somatosensory evoked potentials had become an important prognostic tool for coma recovery, especially in comatose survivors of cardiac arrest. In this population, the bilateral absence of cortical somatosensory evoked potentials has nearly 100% specificity for death or persistent vegetative state. Historically, EP has been regarded as a negative prognostic test, that is, the absence of cortical potentials is associated with poor outcomes while the presence cortical potentials are prognostically indeterminate. In recent studies, the presence of middle-latency and long-latency potentials as well as the amplitude of cortical potentials is more specific for good outcomes. Event-related potentials, particularly mismatch negativity of complex auditory patterns, is emerging as an important positive prognostic test in patients under comatose. Multimodality predictive algorithms that combine somatosensory evoked potentials, event-related potentials, and clinical and radiographic factors are gaining favor for coma prognostication.

Introduction HIV epidemics in the Asia-Pacific region are concentrated among men who have sex with men (MSM) and other key populations. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention intervention and could be a potential game changer in the region. We discuss the progress towards PrEP implementation in the Asia-Pacific region, including opportunities and barriers. Discussion Awareness about PrEP in the Asia-Pacific is still low and so are its levels of use. A high proportion of MSM who are aware of PrEP are willing to use it. Key PrEP implementation barriers include poor knowledge about PrEP, limited access to PrEP, weak or non-existent HIV prevention programmes for MSM and other key populations, high cost of PrEP, stigma and discrimination against key populations and restrictive laws in some countries. Only several clinical trials, demonstration projects and a few larger-scale implementation studies have been implemented so far in Thailand and Australia. However, novel approaches to PrEP implementation have emerged: researcher-, facility- and community-led models of care, with PrEP services for fee and for free. The WHO consolidated guidelines on HIV testing, treatment and prevention call for an expanded access to PrEP worldwide and have provided guidance on PrEP implementation in the region. Some countries like Australia have released national PrEP guidelines. There are growing community leadership and consultation processes to initiate PrEP implementation in Asia and the Pacific. Conclusions Countries of the Asia-Pacific region will benefit from adding PrEP to their HIV prevention packages, but for many this is a critical step that requires resourcing. Having an impact on the HIV epidemic requires investment. The next years should see the region transitioning from limited PrEP implementation projects to growing access to PrEP and expansion of HIV prevention programmes. PMID:27760688

Psychologists abandon the Nuremberg ethic: concerns for detainee interrogations.

Pope, Kenneth S; Gutheil, Thomas G

2009-01-01

In the aftermath of 9-11, the American Psychological Association, one of the largest U.S. health professions, changed its ethics code so that it now runs counter to the Nuremberg Ethic. This historic post-9-11 change allows psychologists to set aside their ethical responsibilities whenever they are in irreconcilable conflict with military orders, governmental regulations, national and local laws, and other forms of governing legal authority. This article discusses the history, wording, rationale, and implications of the ethical standard that U.S. psychologists adopted 7 years ago, particularly in light of concerns over health care professionals' involvement in detainee interrogations and the controversy over psychologists' prominent involvement in settings like the Guantánamo Bay Detainment Camp and the Abu Ghraib prison. It discusses possible approaches to the complex dilemmas arising when ethical responsibilities conflict with laws, regulations, or other governing legal authority.

Epstein-Barr Virus Nuclear Antigen Leader Protein Coactivates EP300.

Epstein-Barr virus nuclear antigen (EBNA) leader protein (EBNALP) is one of the first viral genes expressed upon B-cell infection. EBNALP is essential for EBV-mediated B-cell immortalization. EBNALP is thought to function primarily by coactivating EBNA2-mediated transcription. Chromatin immune precipitation followed by deep sequencing (ChIP-seq) studies highlight that EBNALP frequently cooccupies DNA sites with host cell transcription factors (TFs), in particular, EP300, implicating a broader role in transcription regulation. In this study, we investigated the mechanisms of EBNALP transcription coactivation through EP300. EBNALP greatly enhanced EP300 transcription activation when EP300 was tethered to a promoter. EBNALP coimmunoprecipitated endogenous EP300 from lymphoblastoid cell lines (LCLs). EBNALP W repeat serine residues 34, 36, and 63 were required for EP300 association and coactivation. Deletion of the EP300 histone acetyltransferase (HAT) domain greatly reduced EBNALP coactivation and abolished the EBNALP association. An EP300 bromodomain inhibitor also abolished EBNALP coactivation and blocked the EP300 association with EBNALP. EBNALP sites cooccupied by EP300 had significantly higher ChIP-seq signals for sequence-specific TFs, including SPI1, RelA, EBF1, IRF4, BATF, and PAX5. EBNALP- and EP300-cooccurring sites also had much higher H3K4me1 and H3K27ac signals, indicative of activated enhancers. EBNALP-only sites had much higher signals for DNA looping factors, including CTCF and RAD21. EBNALP coactivated reporters under the control of NF-κB or SPI1. EP300 inhibition abolished EBNALP coactivation of these reporters. Clustered regularly interspaced short palindromic repeat interference targeting of EBNALP enhancer sites significantly reduced target gene expression, including that of EP300 itself. These data suggest a previously unrecognized mechanism by which EBNALP coactivates transcription through subverting of EP300 and thus affects the expression of

Abnormal placental development and early embryonic lethality in EpCAM-null mice.

Directory of Open Access Journals (Sweden)

Keisuke Nagao

Full Text Available BACKGROUND: EpCAM (CD326 is encoded by the tacstd1 gene and expressed by a variety of normal and malignant epithelial cells and some leukocytes. Results of previous in vitro experiments suggested that EpCAM is an intercellular adhesion molecule. EpCAM has been extensively studied as a potential tumor marker and immunotherapy target, and more recent studies suggest that EpCAM expression may be characteristic of cancer stem cells. METHODOLOGY/PRINCIPAL FINDINGS: To gain insights into EpCAM function in vivo, we generated EpCAM -/- mice utilizing an embryonic stem cell line with a tacstd1 allele that had been disrupted. Gene trapping resulted in a protein comprised of the N-terminus of EpCAM encoded by 2 exons of the tacstd1 gene fused in frame to betageo. EpCAM +/- mice were viable and fertile and exhibited no obvious abnormalities. Examination of EpCAM +/- embryos revealed that betageo was expressed in several epithelial structures including developing ears (otocysts, eyes, branchial arches, gut, apical ectodermal ridges, lungs, pancreas, hair follicles and others. All EpCAM -/- mice died in utero by E12.5, and were small, developmentally delayed, and displayed prominent placental abnormalities. In developing placentas, EpCAM was expressed throughout the labyrinthine layer and by spongiotrophoblasts as well. Placentas of EpCAM -/- embryos were compact, with thin labyrinthine layers lacking prominent vascularity. Parietal trophoblast giant cells were also dramatically reduced in EpCAM -/- placentas. CONCLUSION: EpCAM was required for differentiation or survival of parietal trophoblast giant cells, normal development of the placental labyrinth and establishment of a competent maternal-fetal circulation. The findings in EpCAM-reporter mice suggest involvement of this molecule in development of vital organs including the gut, kidneys, pancreas, lungs, eyes, and limbs.

EpCAM (CD326) is encoded by the tacstd1 gene and expressed by a variety of normal and malignant epithelial cells and some leukocytes. Results of previous in vitro experiments suggested that EpCAM is an intercellular adhesion molecule. EpCAM has been extensively studied as a potential tumor marker and immunotherapy target, and more recent studies suggest that EpCAM expression may be characteristic of cancer stem cells. To gain insights into EpCAM function in vivo, we generated EpCAM -/- mice utilizing an embryonic stem cell line with a tacstd1 allele that had been disrupted. Gene trapping resulted in a protein comprised of the N-terminus of EpCAM encoded by 2 exons of the tacstd1 gene fused in frame to betageo. EpCAM +/- mice were viable and fertile and exhibited no obvious abnormalities. Examination of EpCAM +/- embryos revealed that betageo was expressed in several epithelial structures including developing ears (otocysts), eyes, branchial arches, gut, apical ectodermal ridges, lungs, pancreas, hair follicles and others. All EpCAM -/- mice died in utero by E12.5, and were small, developmentally delayed, and displayed prominent placental abnormalities.

Bone marrow (BM)–derived hematopoietic cells, which are major components of tumor stroma, determine the tumor microenvironment and regulate tumor phenotypes. Cyclooxygenase (COX)−2 and endogenous prostaglandins are important determinants for tumor growth and tumor-associated angiogenesis; however, their contributions to stromal formation and angiogenesis remain unclear. In this study, we observed that Lewis lung carcinoma cells implanted in wild-type mice formed a tumor mass with extensive stromal formation that was markedly suppressed by COX-2 inhibition, which reduced the recruitment of BM cells. Notably, COX-2 inhibition attenuated CXCL12/CXCR4 expression as well as expression of several other chemokines. Indeed, in a Matrigel model, prostaglandin (PG) E2 enhanced stromal formation and CXCL12/CXCR4 expression. In addition, a COX-2 inhibitor suppressed stromal formation and reduced expression of CXCL12/CXCR4 and a fibroblast marker (S100A4) in a micropore chamber model. Moreover, stromal formation after tumor implantation was suppressed in EP3−/− mice and EP4−/− mice, in which stromal expression of CXCL12/CXCR4 and S100A4 was reduced. The EP3 or EP4 knockout suppressed S100A4+ fibroblasts, CXCL12+, and/or CXCR4+ stromal cells as well. Immunofluorescent analyses revealed that CXCL12+CXCR4+S100A4+ fibroblasts mainly comprised stromal cells and most of these were recruited from the BM. Additionally, either EP3- or EP4-specific agonists stimulated CXCL12 expression by fibroblasts in vitro. The present results address the novel activities of COX-2/PGE2-EP3/EP4 signaling that modulate tumor biology and show that CXCL12/CXCR4 axis may play a crucial role in tumor stromal formation and angiogenesis under the control of prostaglandins.

The Electro-Polishing (EP) process is the best candidate of final surface treatment for the production of ILC cavities. Nevertheless, the broad distribution of the gradient caused by field emitters in cavities is sitll a serious problem for the EP process. A candidate source of field emitter is the sulfur component which is produced in the EP process and remains the inner-surface of cavities. We studied the effect of Ethanole- and degreaser-rinse processes after the EP process by a unique method. Moreover, we tried to test the sponge cleaning as the post-EP process to remove the field emitter inside the cavcity. This article describe the results of series tests of the post-EP process at KEK.

EpsA is an essential gene in exopolysaccharide production in Lactobacillus johnsonii FI9785.

2016-07-01

Lactobacillus johnsonii FI9785 has an eps gene cluster which is required for the biosynthesis of homopolymeric exopolysaccharides (EPS)-1 and heteropolymeric EPS-2 as a capsular layer. The first gene of the cluster, epsA, is the putative transcriptional regulator. In this study we showed the crucial role of epsA in EPS biosynthesis by demonstrating that deletion of epsA resulted in complete loss of both EPS-1 and EPS-2 on the cell surface. Plasmid complementation of the epsA gene fully restored EPS production, as confirmed by transmission electron microscopy and nuclear magnetic resonance (NMR) analysis. Furthermore, this complementation resulted in a twofold increase in the expression levels of this gene, which almost doubled amounts of EPS production in comparison with the wild-type strain. Analysis of EPS by NMR showed an increased ratio of the heteropolysaccharide to homopolysaccharide in the complemented strain and allowed identification of the acetylated residue in EPS-2 as the (1,4)-linked βGlcp unit, with the acetyl group located at O-6. These findings indicate that epsA is a positive regulator of EPS production and that EPS production can be manipulated by altering its expression. © 2015 The Authors.

OMEGA EP is a new high-energy petawatt laser system under construction at the University of Rochester's Laboratory for Laser Energetics. This paper describes our designs for two diagnostics critical to OMEGA EP's mission. The focal-spot diagnostic (FSD) is responsible for characterizing the focal spot of OMEGA EP's off-axis parabolic mirror at full energy. The ultrafast temporal diagnostic (UTD) is responsible for characterizing pulse shapes of full-energy target shots ranging in width from <1 to 100 ps as well as setting the desired pulse width before the shot. These diagnostics will enable, for the first time, complete spatial and temporal characterization of the focus of a high-energy petawatt laser at full energy

Epidermal growth factor pathway substrate 15, Eps15

DEFF Research Database (Denmark)

Salcini, A E; Chen, H; Iannolo, G

1999-01-01

Eps15 was originally identified as a substrate for the kinase activity of the epidermal growth factor receptor (EGFR). Eps15 has a tripartite structure comprising a NH2-terminal portion, which contains three EH domains, a central putative coiled-coil region, and a COOH-terminal domain containing...... multiple copies of the amino acid triplet Aspartate-Proline-Phenylalanine. A pool of Eps15 is localized at clathrin coated pits where it interacts with the clathrin assembly complex AP-2 and a novel AP-2 binding protein, Epsin. Perturbation of Eps15 and Epsin function inhibits receptor-mediated endocytosis...... of EGF and transferrin, demonstrating that both proteins are components of the endocytic machinery. Since the family of EH-containing proteins is implicated in various aspects of intracellular sorting, biomolecular strategies aimed at interfering with these processes can now be envisioned...

Full Text Available A educação especial tem sido um contexto de inserção do psicólogo na área educacional. À luz das políticas de inclusão vigentes, a atuação do psicólogo se volta à promoção de práticas educacionais que favoreçam a participação e aprendizado de todos os alunos. A formação de profissionais na área da educação demanda o estudo das necessidades sociais que irão atender. Somente a partir de dados concretos acerca do contexto e das possibilidades de intervenção pode-se identificar os conhecimentos que deverão ser ensinados. Entretanto, são raros os estudos que investigam as formas contemporâneas de intervenção da psicologia na educação especial. Assim, reunir dados sobre essa atuação permite instrumentalizar a reflexão sobre a formação em psicologia educacional. Esse trabalho é resultado de uma pesquisa qualitativa e exploratória que objetivou descrever as características da atuação de psicólogos da Grande Florianópolis vinculados à instituições de educação especial. Os dados foram coletados por meio de entrevistas semiestruturadas. As categorizações foram decorrentes do dialogo estabelecido nas entrevistas e, portanto, constituídas posteriormente. A análise dos dados permitiu verificar a sobreposição das três formas de intervenção que historicamente definiram a atuação do psicólogo nessa área, a saber, a segregação, a integração e a inclusão, sendo o foco principal de atuação centrada no aluno com queixa escolar e/ou com suspeita de deficiência intelectual. Diante disso, conclui-se esse estudo ressaltando a importância dos psicólogos refletirem sobre as implicações das políticas inclusivas para sua prática profissional.In the field of education, special education has been context in which psychologists have a place.

Exopolysaccharide (EPS synthesis by Oenococcus oeni: from genes to phenotypes.

Directory of Open Access Journals (Sweden)

Maria Dimopoulou

Full Text Available Oenococcus oeni is the bacterial species which drives malolactic fermentation in wine. The analysis of 50 genomic sequences of O. oeni (14 already available and 36 newly sequenced ones provided an inventory of the genes potentially involved in exopolysaccharide (EPS biosynthesis. The loci identified are: two gene clusters named eps1 and eps2, three isolated glycoside-hydrolase genes named dsrO, dsrV and levO, and three isolated glycosyltransferase genes named gtf, it3, it4. The isolated genes were present or absent depending on the strain and the eps gene clusters composition diverged from one strain to another. The soluble and capsular EPS production capacity of several strains was examined after growth in different culture media and the EPS structure was determined. Genotype to phenotype correlations showed that several EPS biosynthetic pathways were active and complementary in O. oeni. Can be distinguished: (i a Wzy-dependent synthetic pathway, allowing the production of heteropolysaccharides made of glucose, galactose and rhamnose, mainly in a capsular form, (ii a glucan synthase pathway (Gtf, involved in β-glucan synthesis in a free and a cell-associated form, giving a ropy phenotype to growth media and (iii homopolysaccharide synthesis from sucrose (α-glucan or β-fructan by glycoside-hydrolases of the GH70 and GH68 families. The eps gene distribution on the phylogenetic tree was examined. Fifty out of 50 studied genomes possessed several genes dedicated to EPS metabolism. This suggests that these polymers are important for the adaptation of O. oeni to its specific ecological niche, wine and possibly contribute to the technological performance of malolactic starters.

The aim of this study was to clarify, using a nationwide survey, what is perceived as necessary knowledge and skills for psychologists involved in cancer palliative care in Japan, the expectations of medical staff members, and the degree to which these expectations are met. We conducted a questionnaire survey of psychologists involved in cancer palliative care. A total of 419 psychologists from 403 facilities were asked to fill out the questionnaire and return it anonymously. Some 401 psychologists (89 males, 310 females, and 2 unspecified; mean age, 37.2 ± 9.5 years) responded about necessary knowledge and skills for psychologists working in cancer palliative care, the necessity for training, expectations at their current workplace, and the degree to which expectations are met. More than 90% of participants responded that many kinds of knowledge and skills related to the field of cancer palliative care are necessary. Over 80% of participants indicated a necessity for training related to these knowledge and skills. Although more than 50% (range, 50.1-85.8%) of participants responded that such services as "cooperation with medical staff within a hospital," "handling patients for whom psychological support would be beneficial," and "assessment of patients' mental state" were expected at their workplace, fewer than 60% (31.4-56.9%) responded that they actually performed these roles. Our results show that many psychologists in cancer palliative care feel unable to respond to the expectations at their current workplace and that they require more adequate knowledge and skills related to cancer palliative care to work effectively. No other nationwide surveys have generated this type of information in Japan, so we believe that the results of our study are uniquely important.

The role of extracellular polymeric substances (EPS) in Cd adsorption by Bacillus subtilis and Pseudomonas putida was investigated using a combination of batch adsorption experiments, potentiometric titrations, Fourier transform infrared spectroscopy (FTIR). An increased adsorption capacity of Cd was observed for untreated bacteria relative to that for EPS-free bacteria. Surface complexation modeling of titration data showed the similar pK{sub a} values of functional groups (carboxyl, phosphate and hydroxyl) between untreated and EPS-free bacteria. However, site concentrations on the untreated bacteria were found to be higher than those on the EPS-free bacteria. FTIR spectra also showed that no significant difference in peak positions was observed between untreated and EPS-free bacteria and carboxyl and phosphate groups were responsible for Cd adsorption on bacterial cells. The information obtained in this study is of fundamental significance for understanding the interaction mechanisms between heavy metals and biofilms in natural environments. - Highlights: > The presence of EPS on bacterial surfaces facilitates the adsorption of Cd. > The promoting effects on Cd adsorption are more remarkable on Gram-positive B. subtilis cells than that on Gram-negative P. putida cells. > Carboxyl and phosphate groups are mostly responsible for Cd binding on untreated and EPS-free cells. > Intact bacterial cells and EPS-free cells have similar binding mechanisms for Cd. - Intact bacterial cells and EPS-free cells have similar binding mechanisms for Cd.

Circulating tumor cells (CTCs) are the potential precursors of metastatic disease. Most assays established for the enumeration of CTCs so far–including the gold standard CellSearch—rely on the expression of the cell surface marker epithelial cell adhesion molecule (EpCAM). But, these approaches may not detect CTCs that express no/low levels of EpCAM, e.g. by undergoing epithelial-to-mesenchymal transition (EMT). Here we present an enrichment strategy combining different antibodies specific for surface proteins and extracellular matrix (ECM) components to capture an EpCAMlow/neg cell line and EpCAMneg CTCs from blood samples of breast cancer patients depleted for EpCAM-positive cells. The expression of respective proteins (Trop2, CD49f, c-Met, CK8, CD44, ADAM8, CD146, TEM8, CD47) was verified by immunofluorescence on EpCAMpos (e.g. MCF7, SKBR3) and EpCAMlow/neg (MDA-MB-231) breast cancer cell lines. To test antibodies and ECM proteins (e.g. hyaluronic acid (HA), collagen I, laminin) for capturing EpCAMneg cells, the capture molecules were first spotted in a single- and multi-array format onto aldehyde-coated glass slides. Tumor cell adhesion of EpCAMpos/neg cell lines was then determined and visualized by Coomassie/MitoTracker staining. In consequence, marginal binding of EpCAMlow/neg MDA-MB-231 cells to EpCAM-antibodies could be observed. However, efficient adhesion/capturing of EpCAMlow/neg cells could be achieved via HA and immobilized antibodies against CD49f and Trop2. Optimal capture conditions were then applied to immunomagnetic beads to detect EpCAMneg CTCs from clinical samples. Captured CTCs were verified/quantified by immunofluorescence staining for anti-pan-Cytokeratin (CK)-FITC/anti-CD45 AF647/DAPI. In total, in 20 out of 29 EpCAM-depleted fractions (69%) from 25 metastatic breast cancer patients additional EpCAMneg CTCs could be identified [range of 1–24 CTCs per sample] applying Trop2, CD49f, c-Met, CK8 and/or HA magnetic enrichment.

Jeanie L Y Cheong

Full Text Available OBJECTIVES: Extremely preterm (EP survivors have smaller brains, lower IQ, and worse educational achievement than their term-born peers. The contribution of smaller brain size to the IQ and educational disadvantages of EP is unknown. This study aimed (i to compare brain volumes from multiple brain tissues and structures between EP-born (< 28 weeks and term-born (≥ 37 weeks control adolescents, (ii to explore the relationships of brain tissue volumes with IQ and basic educational skills and whether this differed by group, and (iii to explore how much total brain tissue volume explains the underperformance of EP adolescents compared with controls. METHODS: Longitudinal cohort study of 148 EP and 132 term controls born in Victoria, Australia in 1991-92. At age 18, magnetic resonance imaging-determined brain volumes of multiple tissues and structures were calculated. IQ and educational skills were measured using the Wechsler Abbreviated Scale of Intelligence (WASI and the Wide Range Achievement Test(WRAT-4, respectively. RESULTS: Brain volumes were smaller in EP adolescents compared with controls (mean difference [95% confidence interval] of -5.9% [-8.0, -3.7%] for total brain tissue volume. The largest relative differences were noted in the thalamus and hippocampus. The EP group had lower IQs(-11.9 [-15.4, -8.5], spelling(-8.0 [-11.5, -4.6], math computation(-10.3 [-13.7, -6.9] and word reading(-5.6 [-8.8, -2.4] scores than controls; all p-values<0.001. Volumes of total brain tissue and other brain tissues and structures correlated positively with IQ and educational skills, a relationship that was similar for both the EP and controls. Total brain tissue volume explained between 20-40% of the IQ and educational outcome differences between EP and controls. CONCLUSIONS: EP adolescents had smaller brain volumes, lower IQs and poorer educational performance than controls. Brain volumes of multiple tissues and structures are related to IQ and

Preparing for the Rollout of Pre-Exposure Prophylaxis (PrEP: A Vignette Survey to Identify Intended Sexual Behaviors among Women in Kenya and South Africa if Using PrEP.

Directory of Open Access Journals (Sweden)

Amy Corneli

Full Text Available Several clinical trials have demonstrated the efficacy of pre-exposure prophylaxis (PrEP in reducing HIV risk. One concern with introducing PrEP is whether users will engage in riskier sexual behaviors.We assessed the effect that PrEP may have on sexual risk behaviors by administering a survey to 799 women in Bondo, Kenya, and Pretoria, South Africa. Participants were asked about their sexual behavior intentions twice--once as if they were taking PrEP and once as if they were not taking PrEP--within four risk situations (vignettes. They responded using a 5-point ordinal scale. We used a series of linear mixed effects models with an unstructured residual covariance matrix to estimate the between- and within-subject differences in the mean likelihood of engaging in risky sexual behavior across the PrEP and non-PrEP contexts. We also calculated the total percentage of participants who reported a greater likelihood of engaging in risky sexual behavior if taking PrEP than if not taking PrEP, by vignette.We found statistically significant differences in the mean likelihood of engaging in risky sexual behavior with the between-subject comparison (-0.17, p < 0.01 and with the within-subject comparison (-0.31, p < 0.001. Depending on the vignette, 27% to 40% of participants reported a greater likelihood of engaging in risky sexual behavior if taking PrEP than if not taking PrEP.Our findings indicate that modest increases in risky sexual behavior could occur with PrEP. Although responses from the majority of participants suggest they would not be more likely to engage in risky sexual behavior if they took PrEP, a substantial proportion might. Programs rolling out PrEP should be prepared to assist similar women in making informed choices about reducing their risk of HIV and about their sexual health beyond HIV prevention.

1998-01-01

A group of European utilities, along with Westinghouse and its industrial partner GENESI (an Italian consortium including ANSALDO and FIAT) initiated a program to evaluate Westinghouse passive nuclear plant technology for application in Europe. The European utility group consisted of: Agrupacion electrica para al Desarrollo Technologico Nuclear (DTN), Spain; Electricite de France; ENEL, SpA., Italy; IVO Power Engineering, Ltd., Finland; Scottish Nuclear Limited (acting for itself on behalf of Nuclear Electric plc, U.K.; Tractebel Energy Engineering, Belgium; UAK (represented by NOK-Beznau), Switzerland; and Vattenfall AB, Ringhals, Sweden. The European Passive Plant (EPP) program, which began in 1994, is an evaluation of the Westinghouse 600 MWe AP 600 and 1000 MWe Simplified Pressurized Water Reactor (SPWR) designs in meeting the European Utility Requirements (EUR), and where necessary, modifying the design to achieve compliance. Phase 1 or the EPP program was completed and included the two major tasks of evaluating the effect of the EUR on the Westinghouse nuclear island and developing the EP 1000, a 1000 MWe passive plant reference design that conforms to the EUR and would be licensable in Europe. The EP 1000 closely follows the Westinghouse SPWR design for safety systems and containment and the AP 600 design for auxiliary systems. It also includes features that where required to meet the EUR and key European licensing requirements. The primary circuit of the EP 1000 retains most of the general features of the current-day designs, but some evolutionary features to enhance reliability, simplicity of operation, ease of maintenance, and plant safety have been incorporated into the design. The core, reactor vessel, and reactor internals of the EP 1000 are similar to those of currently operating Westinghouse PWR plants, but several new features are included to enhance the performance characteristics. The basic EP 1000 safety philosophy is based on use of inherent

Academic medical centers struggle to achieve parity in advancement and promotions between educators and discovery-oriented researchers in part because of narrow definitions of scholarship, lack of clear criteria for measuring excellence, and barriers to making educational contributions available for peer review. Despite recent progress in expanding scholarship definitions and identifying excellence criteria, these advances are not integrated into educator portfolio (EP) templates or curriculum vitae platforms. From 2013 to 2015, a working group from the Academy of Medical Educators (AME) at the University of California, San Francisco (UCSF) designed a streamlined, criteria-based EP (EP 2.0) template highlighting faculty members' recent activities in education and setting rigorous evaluation methods to enable educational scholarship to be objectively evaluated for academic advancement, AME membership, and professional development. The EP 2.0 template was integrated into the AME application, resulting in high overall satisfaction among candidates and the selection committee and positive feedback on the template's transparency, ease of use, and streamlined format. In 2016, the EP 2.0 template was integrated into the campus-wide curriculum vitae platform and academic advancement system. The authors plan to increase awareness of the EP 2.0 template by educating promotions committees and faculty at UCSF and partnering with other institutions to disseminate it for use. They also plan to study the impact of the template on supporting educators by making their important scholarly contributions available for peer review, providing guidance for professional development, and decreasing disparities in promotions.

EpCAM nuclear localization identifies aggressive Thyroid Cancer and is a marker for poor prognosis

2010-01-01

Proteolytic cleavage of the extracellular domain (EpEx) of Epithelial cell adhesion molecule (EpCAM) and nuclear signaling by its intracellular oncogenic domain Ep-ICD has recently been implicated in increased proliferation of cancer cells. The clinical significance of Ep-ICD in human tumors remains an enigma. EpEx, Ep-ICD and β-catenin immunohistochemistry using specific antibodies was conducted on 58 archived thyroid cancer (TC) tissue blocks from 34 patients and correlated with survival analysis of these patients for up to 17 years. The anaplastic (ATC) and aggressive thyroid cancers showed loss of EpEx and increased nuclear and cytoplasmic accumulation of Ep-ICD. In contrast, the low grade papillary thyroid cancers (PTC) showed membranous EpEx and no detectable nuclear Ep-ICD. The ATC also showed concomitant nuclear expression of Ep-ICD and β-catenin. Kaplan-Meier Survival analysis revealed reduced overall survival (OS) for TC patients showing nuclear Ep-ICD expression or loss of membranous EpEx (p < 0.0004), median OS = 5 months as compared to 198 months for patients who did not show nuclear Ep-ICD or demonstrated only membranous EpE. We report reciprocal loss of membrane EpEx but increased nuclear and cytoplasmic accumulation of Ep-ICD in aggressive TC; nuclear Ep-ICD correlated with poor OS of TC patients. Thus nuclear Ep-ICD localization may serve as a useful biomarker for aggressive TC and may represent a novel diagnostic, prognostic and therapeutic target for aggressive TC

Traditional fermented foods are the best source for the isolation of strains with specific traits to act as functional starters and to keep the biodiversity of the culture collections. Besides, these strains could be used in the formulation of foods claimed to promote health benefits, i.e. those containing probiotic microorganisms. For the rational selection of strains acting as probiotics, several in vitro tests have been proposed. In the current study, we have characterized the probiotic potential of the strain Lactobacillus paraplantarum BGCG11, isolated from a Serbian soft, white, homemade cheese, which is able to produce a "ropy" exopolysaccharide (EPS). Three novobiocin derivative strains, which have lost the ropy phenotype, were characterized as well in order to determine the putative role of the EPS in the probiotic potential. Under chemically gastrointestinal conditions, all strains were able to survive around 1-2% (10(6)-10(7)cfu/ml cultivable bacteria) only when they were included in a food matrix (1% skimmed milk). The strains were more resistant to acid conditions than to bile salts and gastric or pancreatic enzymes, which could be due to a pre-adaptation of the parental strain to acidic conditions in the cheese habitat. The ropy EPS did not improve the survival of the producing strain. On the contrary, the presence of an EPS layer surrounding the strain BGCG11 hindered its adhesion to the three epithelial intestinal cell lines tested, since the adhesion of the three non-ropy derivatives was higher than the parental one and also than that of the reference strain Lactobacillus rhamnosus GG. Aiming to propose a potential target application of these strains as probiotics, the cytokine production of peripheral blood mononuclear cells (PBMC) was analyzed. The EPS-producing L. paraplantarum BGCG11 strain showed an anti-inflammatory or immunosuppressor profile whereas the non-ropy derivative strains induced higher pro-inflammatory response.

Differences regarding job satisfaction and job involvement of psychologists with different dominant career anchors.

Science.gov (United States)

Bester, C L; Mouton, T

2006-08-01

In order to contribute to higher levels of job satisfaction, job involvement and productivity, a match or fit should be established between the dominant career anchor associated with a specific occupation and that of the employee. A career anchor is an individual's set of self-perceived talents, abilities, motives, needs and values that form the nucleus of one's occupational self-concept. Psychologists have always been part of the service orientated careers and therefore one would expect that it is likely that their dominant career anchor would be service orientation. If this is the case, psychologists with service as their dominant career anchor are supposed to have greater job satisfaction and job involvement compared to those with different career anchors. However, according to literature, this assumption is not necessarily correct. The primary goals of the current study were to determine whether in fact service is the dominant career anchor of psychologists in the Free State and whether there are significant differences regarding job satisfaction and job involvement between psychologists with and without service as their dominant career anchor. A third goal was to determine whether psychologists with different dominant career anchors differ significantly from one another regarding job satisfaction and job involvement. Questionnaires measuring career orientations, job satisfaction and job involvement were sent to 165 of the 171 registered psychologists in the Free State region. Only 75 psychologists (45,5%) responded which exceeded the traditional return rate of 20 to 30%. Due to the small sample of respondents, a nonparametric statistical test, namely the Mann Whitney U test was conducted to determine possible differences. An analysis of the data showed that 21 respondents had entrepreneurship as their dominant career orientation while 12 fell in the technical/functional, 12 in the challenging, 9 in the service and 8 in the autonomy categories of dominant

HIV prevention method preferences were evaluated among 512 U.S. men who have sex with men (MSM; median age: 22 years). Approximately 90 % consistently preferred one option across pairwise comparisons of condoms, daily oral pre-exposure prophylaxis (PrEP), and long-acting PrEP delivered via either an injectable or one of two types of PrEP implants differing in visibility. Condoms were most frequently preferred (33.8 %), followed by non-visible implants (21.5 %), and oral PrEP (17.0 %); HIV risk was reported by more choosing implants. In a follow-up question comparing the four PrEP options only, daily oral pills and non-visible implants were most frequently preferred (35.5 and 34.3 %, respectively), followed by injections (25.2 %) and visible implants (4.3 %). An inductive, open-coding approach determined that convenience, duration of protection, and privacy were the most commonly cited reasons for a PrEP method choice, and associated with self-report of HIV risk. Tailoring PrEP product development to privacy and other concerns important to those at highest HIV risk may improve HIV prevention.

We use a collaborative autoethnographical approach to explore the themes of influence, curiosity, rich insight and sincerity. We attempt to bring honesty and transparency to our collaborative dialogue about our previous work on vicarious trauma (VT and secondary traumatic stress (STS, as well as how our themes are revealed in the different paths we have taken as counselling psychologists since our earlier collaboration. We consider what it means to influence, to be influential, and to be influenced. Through our dialogue, we try to speak with authenticity about our experiences as colleagues, counselling psychologists, scientist practitioners, and human beings. We discuss both the potential contribution of autoethnographical approaches and the challenges of using these methods, for counselling psychologists.

Extracellular polysaccharide (EPS) antigens produced by different mould species were purified and partially characterized. Purification included (NH4)2SO4 treatment, Sepharose CL-4B column chromatography and Con A-sepharose chromatography. The EPS of Penicillium digitatum, Mucor racemosus and Cladosporium cladosporioides showed high antigenic capacities. Immunologically the EPS were partially genus-specific, but cross-reactivity was observed. The EPS antigens produced by species of Penicillium, Aspergillus repens and Geotrichum candidum lost their immunological activity upon heating (100 degrees C) at pH 1.8, while the EPS antigen of M. racemosus, Rhizopus oligosporus and C. cladosporioides were stable under the same conditions. The dominant monosaccharides present in the EPS antigen were mannose, galactose and glucose. The EPS obtained from cultures of M. racemosus and R. oligosporus also contained rhamnose. In the EPS produced by Penicillium spp. and A. repens the galactose residues were determined to be immunodominant.

Prostaglandin E2 is a potent endogenous molecule that binds to four different G-protein-coupled receptors: EP1-4. Each of these receptors is a valuable drug target, with distinct tissue localisation and signalling pathways. We review the structural features of EP modulators required for subtype-selective activity, as well as the structural requirements for improved pharmacokinetic parameters. Novel EP receptor subtype selective agonists and antagonists appear to be valuable drug candidates in the therapy of many pathophysiological states, including ulcerative colitis, glaucoma, bone healing, B cell lymphoma, neurological diseases, among others, which have been studied in vitro, in vivo and in early phase clinical trials.

Rendina, H Jonathon; Whitfield, Thomas H F; Grov, Christian; Starks, Tyrel J; Parsons, Jeffrey T

2017-01-01

Much of the data on the acceptability of HIV Pre-Exposure Prophylaxis (PrEP) is based on willingness to take PrEP (i.e., hypothetical receptivity) rather than actual intentions (i.e., planned behavioral action) to do so. We sought to examine differences between hypothetical willingness and behavioral intentions to begin PrEP in a national sample of gay and bisexual men (GBM) across the U.S. We utilized data collected in 2015 to examine differences between those Unwilling (42.6% n = 375), Willing but not intending (41.4%, n = 365), and willing and Intending to take PrEP (15.9%, n = 140) in a multivariable, multinomial logistic regression. Men with less education had higher odds of Intending to take PrEP. Compared to men unsure about PrEP's efficacy, those who believed PrEP was at least 90% efficacious had higher odds of Intending to take PrEP. Those who saw themselves as appropriate candidates for PrEP had higher odds of Intending to take PrEP while those who saw themselves as inappropriate candidates for PrEP had lower odds of Intending to take PrEP in comparison to men unsure if they were appropriate candidates. Increased motivation for condom non-use because of perceived sexual pressure by partners was associated with higher odds of Intending to take PrEP. The groups did not differ by risk behavior nor recent STI diagnosis. Overall, the distinction between willingness and intentions to take PrEP was meaningful and may help explain disparities between PrEP acceptability and uptake. While much of the literature has focused on hypothetical willingness to take PrEP, these results highlight the importance of simultaneously assessing willingness and intentions when examining correspondence with uptake and developing interventions to increase PrEP uptake.

2014-01-01

Although relatively rare, encapsulating peritoneal sclerosis (EPS) is nonetheless a major concern within the renal community. Risk of developing EPS is associated with long-term peritoneal dialysis (PD). High mortality was previously reported, although surgery has since improved outcomes. Research into EPS focuses on imaging and early detection methods, genetics, biomarkers and preventive strategies. No previous studies have examined patients' experiences of EPS. The aim of the present study was to explore the experience of patients who have undergone surgery for EPS in one center in the North of England. A qualitative phenomenological approach, involving in-depth interviews, was adopted. Nine participants were recruited out of a total of 18 eligible. Most participants were interviewed twice over a 12-month period (October 2009 to October 2010). Interpretive data analysis was conducted, following the philosophical tradition of hermeneutics, to draw out themes from the data. Data collection and analysis took place concurrently and participants were sent a summary of their first interview to allow a period of reflection prior to the subsequent interview. EPS presented the most serious challenge participants had faced since developing chronic kidney disease (CKD). Three major themes were identified, each with subcategories. The key issues for patients were related to identification of early symptoms and lack of understanding. The patients' sense of 'not being heard' by health care professionals led to a loss of trust and enhanced their feelings of uncertainty. The enormity of the surgery, the suffering, and what they had to endure had an enormous impact, but an overriding aspect of this experience was also the loss they felt for their independence and for the PD therapy over which they had control. The findings of this study highlight a number of important issues relevant to clinical practice, including lack of information and understanding of EPS, particularly its

The epsN gene, located in the eps gene cluster of this strain, is associated with EPS biosynthesis. Bioinformatics analysis of this gene was performed. The conserved domain analysis showed that the EpsN protein contained MATE-Wzx-like domains. Then the epsN gene was amplified to construct the recombinant expression vector pMG36e-epsN. The results showed that the EPS yields of the recombinants were significantly improved. By determining the yields of EPS and intracellular polysaccharide, it was considered that epsN gene could play its Wzx flippase role in the EPS biosynthesis. This is the first time to prove the effect of EpsN on L. kefiranofaciens EPS biosynthesis and further prove its functional property.

The acute inpatient setting poses potential challenges to delivering one-to-one psychological therapy; however, there is little research on the experiences of both receiving and delivering therapies in this environment. This qualitative study aimed to explore service users' and psychologists' experiences of undertaking individual therapy in acute inpatient units. It focused on the relationship between service users and psychologists, what service users found helpful or unhelpful, and how psychologists attempted to overcome any challenges in delivering therapy. The study used a qualitative, interview-based design. Eight service users and the six psychologists they worked with were recruited from four acute inpatient wards. They participated in individual semi-structured interviews eliciting their perspectives on the therapy. Service users' and psychologists' transcripts were analysed together using Braun and Clarke's (2006, Qualitative Research in Psychology, 3, 77) method of thematic analysis. The accounts highlighted the importance of forming a 'human' relationship - particularly within the context of the inpatient environment - as a basis for therapeutic work. Psychological therapy provided valued opportunities for meaning-making. To overcome the challenges of acute mental health crisis and environmental constraints, psychologists needed to work flexibly and creatively; the therapeutic work also extended to the wider context of the inpatient unit, in efforts to promote a shared understanding of service users' difficulties. Therapeutic relationships between service users and clinicians need to be promoted more broadly within acute inpatient care. Psychological formulation can help both service users and ward staff in understanding crisis and working collaboratively. Practice-based evidence is needed to demonstrate the effectiveness of adapted psychological therapy models. Developing 'human' relationships at all levels of acute inpatient care continues to be an

The use of EPS underneath shallow foundation do not show the correlation with the seismic response of structure if there is no interface element constructed. Variation of EPS size used were contributed to the acceleration and displacement of  structure with shallow foundation. As the larger size of EPS applied, the larger reduction of seismic responses will be obtained.

It is increasingly clear that the HIV response will not be sustainable if the number of infections is not significantly reduced. For two decades, research has been ongoing to identify new behavioural and biomedical strategies to prevent HIV infection. In the past few years, the efficacy of several new strategies has been demonstrated, including oral pre-exposure prophylaxis (PrEP; i.e. daily use of tenofovir/emtricitabine). Because several social, political and logistic barriers remain, however, optimal PrEP implementation will require a better dissemination of new evidence in a number of areas and additional implementation research from various disciplinary perspectives (i.e. social science, policy and ethics; health systems; and economics, including cost-effectiveness studies). Discussion of new evidence on those topics, as well as case studies of potential PrEP implementation in diverse environments, can improve the understanding of the role that PrEP may play in addressing the global HIV/AIDS epidemic.In light of these needs, the Network for Multidisciplinary Studies in ARV-based HIV Prevention (NEMUS) and the World Health Organization (WHO) were honoured to co-organize a special issue of JIAS aimed at contributing to a scholarly discussion of current conditions surrounding PrEP implementation, potential impact and efficiency, social science concerns and the study of PrEP implementation in specific country cases. The papers included in this monograph identify and cover many of the main aspects of the complex yet promising discussions around PrEP implementation today. This is a collection of timely contributions from global leaders in HIV research and policy that addresses geographic diversity, uses a trans-disciplinary approach and covers a variety of the complex issues raised by PrEP. As this publication will become accessible to all, we hope that it will remain a valuable resource for policy makers, programme managers, researchers and activists around the

PrEP in Europe - expectations, opportunities and barriers.

In contrast to the global trend showing a decline in new HIV infections, the number reported in the World Health Organization (WHO) region of Europe is increasing. Health systems are disparate, but even countries with free access to screening and treatment observe continuing high rates of new infections in key populations, notably men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) is only available in France. This commentary describes the European epidemics and healthcare settings where PrEP could be delivered, how need might be estimated for MSM and the residual barriers to access. Health systems and government commitment to HIV prevention and care, both financial and political, differ considerably between the countries that make up Europe. A common feature is that funds for prevention are a small fraction of funds for care. Although care is generally good, access is limited in the middle-income countries of Eastern Europe and central Asia, and only 19% of people living with HIV received antiretroviral therapy in 2014. It is challenging to motivate governments or civil society to implement PrEP in the context of this unmet treatment need, which is driven by limited national health budgets and diminishing assistance from foreign aid. The high-income countries of Western Europe have hesitated to embrace PrEP for different reasons, initially due to key gaps in the evidence. Now that PrEP has been shown to be highly effective in European MSM in two randomized controlled trials, it is clear that the major barrier is the cost of the drug which is still on patent, although inadequate health systems and diminishing investment in civil society are also key challenges to overcome. The momentum to implement PrEP in European countries is increasing and provides a welcome opportunity to expand and improve clinical services and civil society support focused on HIV and related infections including other sexually transmitted and blood-borne infections.

Awareness of pre-exposure prophylaxis (PrEP) among women who inject drugs in NYC: the importance of networks and syringe exchange programs for HIV prevention.

Science.gov (United States)

Walters, Suzan M; Reilly, Kathleen H; Neaigus, Alan; Braunstein, Sarah

2017-06-29

Women who inject drugs (WWID) are at heightened risk for HIV due to biological, behavioral, and structural factors. Pre-exposure prophylaxis (PrEP) could aid in HIV prevention for WWID. However, little is known about WWID awareness of PrEP, which is a necessary step that must occur before PrEP uptake. We report factors associated with greater awareness among WWID to identify efficient means of awareness dissemination. Data from the 2015 National HIV Behavioral Surveillance (NHBS) system cycle on injection drug use collected in New York City (NYC) were used. Bivariable analyses, using chi-squared statistics, were conducted to examine correlates of awareness of PrEP with socio-demographic, behavioral, and health care variables. Multivariable logistic regression was used to estimate adjusted associations and determine differences in awareness of PrEP. The analysis consisted of 118 WWID. Awareness of PrEP was relatively low (31%), and risk factors were high. In the last 12 months, almost two thirds (65%) reported condomless sex, approximately one third (31%) reported transactional sex, and one third (32%) reported sharing injection equipment. In multivariable logistic regression, increased PrEP awareness was associated with reported transactional sex (AOR 3.32, 95% CI 1.22-9.00) and having a conversation about HIV prevention at a syringe exchange program (SEP) (AOR 7.61, 95% CI 2.65-21.84). We did not find race, education, household income, age, binge drinking, or sexual identity to be significantly associated with PrEP awareness. Large proportions of WWID were unaware of PrEP. These findings suggest that social networks (specifically sex work and SEP networks) are an efficient means for disseminating messaging about prevention materials such as PrEP. We recommend that SEP access increase, SEP processes be adopted in other health care settings, and WWID networks be utilized to increase PrEP awareness.

2014-12-01

The purpose of this study was to empirically investigate Nationally Certified School Psychologists' (NCSP) training in and use of evidence-based interventions (EBIs) for child behavior concerns as well as their reported implementation barriers. A modified Tailored Design Method (TDM; Dillman, Smyth, & Christian, 2009) using up to four mail-based participant contacts was used to obtain survey data (72% usable response rate; n = 392) from a randomly selected national sample of 548 currently practicing NCSPs. Lack of time was rated as the most serious barrier to behavioral EBI implementation, followed by a lack of necessary resources, and financial constraints. Nearly three-quarters (71%) of respondents reported a perceived inadequacy of graduate program training in behavioral EBIs, with a statistically significant difference found between respondents who attended American Psychological Association (APA)-accredited/National Association of School Psychologists (NASP)-approved programs and those who did not. These findings highlight the significant barriers school psychologists encounter when attempting to implement behavioral EBIs within applied practice, as well as the importance of graduate program training in implementation science. Implications for training, practice, and research are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

EPS-LASSO: Test for High-Dimensional Regression Under Extreme Phenotype Sampling of Continuous Traits.

Science.gov (United States)

Xu, Chao; Fang, Jian; Shen, Hui; Wang, Yu-Ping; Deng, Hong-Wen

2018-01-25

Extreme phenotype sampling (EPS) is a broadly-used design to identify candidate genetic factors contributing to the variation of quantitative traits. By enriching the signals in extreme phenotypic samples, EPS can boost the association power compared to random sampling. Most existing statistical methods for EPS examine the genetic factors individually, despite many quantitative traits have multiple genetic factors underlying their variation. It is desirable to model the joint effects of genetic factors, which may increase the power and identify novel quantitative trait loci under EPS. The joint analysis of genetic data in high-dimensional situations requires specialized techniques, e.g., the least absolute shrinkage and selection operator (LASSO). Although there are extensive research and application related to LASSO, the statistical inference and testing for the sparse model under EPS remain unknown. We propose a novel sparse model (EPS-LASSO) with hypothesis test for high-dimensional regression under EPS based on a decorrelated score function. The comprehensive simulation shows EPS-LASSO outperforms existing methods with stable type I error and FDR control. EPS-LASSO can provide a consistent power for both low- and high-dimensional situations compared with the other methods dealing with high-dimensional situations. The power of EPS-LASSO is close to other low-dimensional methods when the causal effect sizes are small and is superior when the effects are large. Applying EPS-LASSO to a transcriptome-wide gene expression study for obesity reveals 10 significant body mass index associated genes. Our results indicate that EPS-LASSO is an effective method for EPS data analysis, which can account for correlated predictors.

Interprofessional Education: Opportunities and Challenges for Psychology.

Ward, Wendy; Zagoloff, Alexandra; Rieck, Cortney; Robiner, William

2018-02-16

This manuscript is an outgrowth of an invited panel presentation at the national Association for Psychologists in Academic Health Centers Conference in 2017 on Interprofessional Education (IPE). IPE is a structured and transformative educational strategy designed to provide active learning experiences where trainees from diverse healthcare professions gain shared content knowledge plus collaboration skills as they learn about, from, and with each other. Collaboration skills include understanding professional role distinctions and overlap, effective team-based communication, shared values/ethics and respect for each other's expertise, and teamwork dynamics. It is increasingly important to expand training beyond the intraprofessional activities in which psychology trainees engage to prepare them to participate in interprofessional collaborative care. As healthcare systems move to team-based collaborative practice and value-based reimbursement models, the profession of psychology needs leaders at every academic health center to facilitate the design and/or implementation of IPE activities. The panel of psychologists presented roles that psychologists play in IPE institutional program design and implementation, graduate training programs, and the perspectives of an early career psychologist and psychology trainee. Opportunities and challenges are highlighted, culminating in a call to action. Psychologists must embrace their identity as health professionals and engage their learners in IPE so that the emerging cognitive schemata of healthcare that is developed includes the profession of psychology. Otherwise, healthcare teams and health professionals will not understand the value, roles, or potential contributions of psychologists in enhancing patient care outcomes, ultimately jeopardizing psychologists' referrals, involvement in healthcare delivery, and career opportunities.

Structures and Logic of EP Implementation and Administration in China

Dieter Grunow

2011-01-01

Full Text Available This paper describes empirical observations gathered during a research project on the implementation of environmental protection (EP policies in China. The project focused on local EP in both urban and rural areas. Policy field analysis was used as a conceptual framework for structuring the observations. The paper develops in three main steps discussing the following topics: 1 Collective problems within the policy field of EP show that EP issues in general are unlike those of other policy fields. Official EP policies in China today resemble those of other countries – but they are separating issues and responsibilities, making local implementation very demanding. 2 China lags behind in its willingness and ability to implement these policies – leading to implementation gaps. To explore the causes and consequences, specific sites in China are described in an extended look at local implementation structures. It was found that although policies in China are basically the same everywhere, the structures for implementing them and the quality of their implementation vary widely with regard to resources, organization, coordination, staff qualifications, personnel placement, and other aspects. 3 Not all of the challenges hampering local implementation of environmental policies were China-specific; however, some of those which are can be described as the macro-context: an ineffective rule of law, insufficient involvement of civil society, and complicated macro-structures of public administration prevent a generally high level of successful EP implementation in China.

When psychologists work with religious clients: applications of the general principles of ethical conduct.

Yarhouse, M A; VanOrman, B T

1999-12-01

Psychologists become more effective and relevant when they appreciate that many clients hold religious values and commitments. Greater awareness of religion and religious values in the lives of clients may aid clinicians' efforts to provide more accurate assessments and effective treatment plans. The authors use the American Psychological Association's (1992) "Ethical Principles of Psychologists and Code of Conduct" as a framework to examine many of the ethical issues relevant when psychologists work with religious clients. This article also provides suggestions for ways in which clinicians may obtain the skills needed to offer competent assessments and interventions with religiously committed clients.

Could FDA approval of pre-exposure prophylaxis make a difference? A qualitative study of PrEP acceptability and FDA perceptions among men who have sex with men.

Science.gov (United States)

Underhill, Kristen; Morrow, Kathleen M; Operario, Don; Mayer, Kenneth H

2014-02-01

The FDA has approved tenofovir-emtricitabine for use as HIV pre-exposure prophylaxis, but it is unknown how approval may affect PrEP acceptability among US men who have sex with men. We conducted 8 focus groups among 38 Rhode Island MSM, including 3 groups among 16 male sex workers and 5 groups among 22 men in the general MSM community. Participants reported wide-ranging beliefs regarding consequences and meanings of FDA approval. Some participants would not use PrEP without approval, while others perceived approval as irrelevant or less significant than other sources of information. Our results suggest that FDA approval sends a signal that directly shapes PrEP acceptability among some MSM, while indirect influences of approval may affect uptake by others. Efforts to educate MSM about PrEP can increase acceptability by incorporating information about FDA approval, and outreach strategies should consider how this information may factor into personal decisions about PrEP use.

Full Text Available Molecular markers for predicting prostate cancer (PCa that would have poor prognosis are urgently needed for a more personalized treatment for patients. Regulated intramembrane proteolysis of Epithelial cell adhesion molecule results in shedding of the extracellular domain (EpEx and release of its intracellular domain (Ep-ICD which triggers oncogenic signaling and might correlate to tumor aggressiveness. This study aimed to explore the potential of Ep-ICD and EpEx to identify PCa that have poor prognosis.Immunohistochemical analysis of Ep-ICD and EpEx was carried out in normal prostate tissues (n = 100, benign prostate hyperplasia (BPH, n = 83, and prostate cancer (n = 249 using domain specific antibodies. The expression of Ep-ICD and EpEx was correlated with clinico- pathological parameters and disease free survival (DFS.Reduced expression of nuclear Ep-ICD and membrane EpEx was observed in PCa in comparison with BPH and normal prostate tissues (p = 0.006, p < 0.001 respectively. For patients who had PCa with Gleason Score less than 7, preserved nuclear Ep-ICD emerged as the most significant marker in multivariate analysis for prolonged DFS, where these patients did not have recurrence during follow up of up to 12 years (p = 0.001.Reduced expression of nuclear Ep-ICD was associated with shorter disease free survival in patients with a Gleason Score less than 7 and may be useful in identifying patients likely to have aggressive tumors with poor prognosis. Furthermore, nuclear Ep-ICD can differentiate between normal and prostate cancer tissues for ambiguous cases.

Role of the Prostaglandin E2 EP1 Receptor in Traumatic Brain Injury

Science.gov (United States)

Glushakov, Alexander V.; Fazal, Jawad A.; Narumiya, Shuh; Doré, Sylvain

2014-01-01

Brain injuries promote upregulation of so-called proinflammatory prostaglandins, notably prostaglandin E2 (PGE2), leading to overactivation of a class of its cognate G-protein-coupled receptors, including EP1, which is considered a promising target for treatment of ischemic stroke. However, the role of the EP1 receptor is complex and depends on the type of brain injury. This study is focused on the investigation of the role of the EP1 receptor in a controlled cortical impact (CCI) model, a preclinical model of traumatic brain injury (TBI). The therapeutic effects of post-treatments with a widely studied EP1 receptor antagonist, SC-51089, were examined in wildtype and EP1 receptor knockout C57BL/6 mice. Neurological deficit scores (NDS) were assessed 24 and 48 h following CCI or sham surgery, and brain immunohistochemical pathology was assessed 48 h after surgery. In wildtype mice, CCI resulted in an obvious cortical lesion and localized hippocampal edema with an associated significant increase in NDS compared to sham-operated animals. Post-treatments with the selective EP1 receptor antagonist SC-51089 or genetic knockout of EP1 receptor had no significant effects on cortical lesions and hippocampal swelling or on the NDS 24 and 48 h after CCI. Immunohistochemistry studies revealed CCI-induced gliosis and microglial activation in selected ipsilateral brain regions that were not affected by SC-51089 or in the EP1 receptor-deleted mice. This study provides further clarification on the respective contribution of the EP1 receptor in TBI and suggests that, under this experimental paradigm, the EP1 receptor would have limited effects in modulating acute neurological and anatomical pathologies following contusive brain trauma. Findings from this protocol, in combination with previous studies demonstrating differential roles of EP1 receptor in ischemic, neurotoxic, and hemorrhagic conditions, provide scientific background and further clarification of potential therapeutic

for endocytosis of the epidermal growth factor receptor (EGFR), the prototypical ligand-inducible receptor, but not of the transferrin receptor (TfR), the prototypical constitutively internalized receptor. Eps15, an endocytic protein that is tyrosine phosphorylated by EGFR, is a candidate for such a function....... Here, we show that tyrosine phosphorylation of Eps15 is necessary for internalization of the EGFR, but not of the TfR. We mapped Tyr 850 as the major in vivo tyrosine phosphorylation site of Eps15. A phosphorylation-negative mutant of Eps15 acted as a dominant negative on the internalization...... of the EGFR, but not of the TfR. A phosphopeptide, corresponding to the phosphorylated sequence of Eps15, inhibited EGFR endocytosis, suggesting that phosphotyrosine in Eps15 serves as a docking site for a phosphotyrosine binding protein. Thus, tyrosine phosphorylation of Eps15 represents the first molecular...

People at high risk for HIV acquisition should be offered pre-exposure prophylaxis (PrEP). Tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) is currently the only medication recommended for pre-exposure prophylaxis (PrEP) by the Centers for Disease Control and Prevention (CDC) in people at high risk for HIV acquisition. This article will review medications currently under investigation and the future landscape of PrEP therapy. Areas covered: This article will review clinical trials that have investigated nontraditional regimens of TDF/FTC, antiretroviral agents from different drug classes such as integrase strand transfer inhibitors (INSTI), nucleoside reverse transcriptase inhibitors (NRTI), and non-nucleoside reverse transcriptase inhibitors (NNRTI) as potential PrEP therapies. Expert commentary: Currently, there are several investigational drugs in the pipeline for PrEP against HIV infection. Increased utilization of PrEP therapy depends on provider identification of people at high risk for HIV transmission. Advances in PrEP development will expand options and access for people and reduce the risk of HIV acquisition.

2015-01-01

A central part of providing evidence-based practice is appropriate cultural competence to facilitate psychological assessment and intervention with diverse clients. At a minimum, cultural competence with lesbian, gay, bisexual, and transgender (LGBT) people involves adequate scientific and supervised practical training, with increasing depth and complexity across training levels. In order to further this goal, we offer 28 recommendations of minimum standards moving toward ideal training for LGBT-specific cultural competence. We review and synthesize the relevant literature to achieve and assess competence across the various levels of training (doctoral, internship, post-doctoral, and beyond) in order to guide the field towards best practices. These recommendations are aligned with educational and practice guidelines set forth by the field and informed by other allied professions in order to provide a roadmap for programs, faculty, and trainees in improving the training of psychologists to work with LGBT individuals.

Previous research highlights barriers to clinical psychologists conducting research, but has rarely examined U.K. clinical psychologists. The study investigated U.K. clinical psychologists' self-reported research output and tested part of a theoretical model of factors influencing their intention to conduct research. Questionnaires were mailed to 1,300 U.K. clinical psychologists. Three hundred and seventy-four questionnaires were returned (29% response-rate). This study replicated in a U.K. sample the finding that the modal number of publications was zero, highlighted in a number of U.K. and U.S. studies. Research intention was bimodally distributed, and logistic regression classified 78% of cases successfully. Outcome expectations, perceived behavioral control and normative beliefs mediated between research training environment and intention. Further research should explore how research is negotiated in clinical roles, and this issue should be incorporated into prequalification training. © 2012 Wiley Periodicals, Inc.

The deposition kinetics of extracellular polymeric substances (EPS) on silica surfaces were examined in both monovalent and divalent solutions under a variety of environmentally relevant ionic strength and pH conditions by employing a quartz crystal microbalance with dissipation (DCM-D). Soluble EPS (SEPS) and bound EPS (BEPS) were extracted from four bacterial strains with different characteristics. Maximum favorable deposition rates (k(fa)) were observed for all EPS at low ionic strengths in both NaCl and CaCl2 solutions. With the increase of ionic strength, k(fa) decreased due to the simultaneous occurrence of EPS aggregation in solutions. Deposition efficiency (alpha; the ratio of deposition rates obtained under unfavorable versus corresponding favorable conditions) for all EPS increased with increasing ionic strength in both NaCl and CaCl2 solutions, which agreed with the trends of zeta potentials and was consistent with the classic Derjaguin-Landau-Verwey-Overbeek (DLVO) theory. Comparison of alpha for SEPS and BEPS extracted from the same strain showed that the trends of alpha did not totally agree with trends of zeta potentials, indicating the deposition kinetics of EPS on silica surfaces were not only controlled by DLVO interactions, but also non-DLVO forces. Close comparison of alpha for EPS extracted from different sources showed alpha increased with increasing proteins to polysaccharides ratio. Subsequent experiments for EPS extracted from the same strain but with different proteins to polysaccharides ratios and from activated sludge also showed that alpha were largest for EPS with greatest proteins to polysaccharides ratio. Additional experiments for pure protein and solutions with different pure proteins to pure saccharides ratios further corroborated that larger proteins to polysaccharides ratio resulted in greater EPS deposition.

Membrane fouling is one of the main constraints of the wide use of membrane bioreactor (MBR) technology. The biomass in MBR systems includes extracellular polymeric substances (EPS), metabolic products of active microbial secretion that adversely affect the membrane performance. Solids retention time (SRT) in the MBR is one of the most important parameters affecting membrane fouling in MBR systems, where fouling is minimized at optimal SRT. Among the operating parameters in MBR systems, SRT is known to strongly influence the ratio of proteins to polysaccharides in the EPS matrix. In this study, we have direct evidence for changes in EPS adherence and viscoelastic properties due to changes in the sludge removal rate that strongly correlate with the membrane fouling rate and EPS composition. EPS were extracted from a UF membrane in a hybrid growth MBR operated at sludge removal rates of 59, 35.4, 17.7, and 5.9 L day(-1) (corresponding SRT of 3, 5, 10, and 30 days, respectively). The EPS adherence and adsorption kinetics were carried out in a quartz crystal microbalance with dissipation monitoring (QCM-D) technology in several adsorption measurements to a gold sensor coated with Polyvinylidene Fluoride (PVDF). EPS adsorption to the sensor surface is characterized by a decrease of the oscillation frequency and an increase in the dissipation energy of the sensor during parallel flow of aqueous media, supplemented with EPS, above the sensor surface. The results from these experiments were further modeled using the Voigt based model, in which the thickness, shear modulus, and shear viscosity values of the adsorbed EPS layers on the PVDF crystal were calculated. The observations in the QCM-D suggested that the elevated fouling of the UF membrane is due to higher adherence of the EPS as well as reduction in viscosity and elasticity of the EPS adsorbed layer and elevation of the EPS fluidity. These results corroborate with confocal laser scanning microscopy (CLSM) image

Gavrilovic, M.

2002-01-01

The paper presents a brief summary of the state of environmental protection in the vicinity of Electric Power Industry of Serbia (EPS) power facilities, both when economy of FR Yugoslavia (FRY) was at an acceptable level and the current situation resulting from a drastic decline of economic power of country and EPS itself, from unfavourable political development from the past period, from the sanctions imposed by UN Security Council, from a prolonged isolation from modern courses worldwide as well as from bombing of facilities during NATO aggression against Yugoslavia. The paper is focused on the analysis of the possibilities of taking certain activities aimed at environmental protection under expected realistic circumstances of EPS recovery and its further development, in accordance with the overall economic recovery and development of the country, and to estimate the price of all environmental protection measures which, would otherwise have been realised in the course of the past period if sanctions of UN Security Council have not been imposed on FR Yugoslavia.

ep possibility for ISABELLE

Wilson, R.

1977-01-01

The feasibility of adding an electron ring to ISABELLE is discussed in terms of cost, physics goals, count rate estimates, the detector requirements, and the possibility of producing intermediate bosons. The purpose of adding an electron ring to ISABELLE must be considered to be the study of e + p → e + x, e - p → νx, and e + p → anti νx. Other processes, such as W production, are less interesting for an ep ring than for a pp ring. However, there may be other new particles--such as leptonic quarks--that only turn up here. These processes are, however, exciting. In a 30 day run at L = 10 32 cm -2 sec -1 300 neutrino events are expected at q 2 > 5000 GeV 2 where the propagator is expected to be less than 1 / 4 . Thus the value of the mass in the propagator can be measured to 5%. The ep cross section would be measured over the momentum transfer range 1 2 2 ). This range is large enough that a logarithmic deviation from scaling can be distinguished easily from a power law approach to scaling

Key developments of the EP1000 design

1999-01-01

In 1994, a group of European utilities initiated, together with Westinghouse and its industrial partner GENESI (an Italian consortium including ANSALDO and FIAT), a program designated EPP (European Passive Plant) to evaluate Westinghouse passive nuclear plant technology for application in Europe. The Phase I of the European Passive Plant program involved the evaluation of the Westinghouse 600 MWe AP600 and 1000 MWe Simplified Pressurized Water Reactor (SPWR) designs against the European Utility Requirements (EUR), and when necessary, the investigation of possible modifications to achieve compliance with the EUR. In Phase 1 of the program, which has been completed in 1996, the following major tasks were accomplished: The impacts of the European Utility Requirements (EUR) on the Westinghouse nuclear island design were evaluated. A 1000 MWe passive plant reference design (EP1000) was developed which conforms to the EUR and is expected to be licensable in Europe. With respect to the NSSS and containment, the EP1000 reference design closely follows those of the Westinghouse SPWR design, while the AP600 design has been taken as the basis for the design of the auxiliary systems. Extensive design and testing efforts have been made for the AP600 and SPWR during the respective multi-year programs. While the results of these programs have been and will continue to be utilised, at the maximum extent, to minimise the work to be performed on the EP1000 design, the compliance with EUR is a key design requirement for the EP1000 The ultimate objective of Phase 2 of the program is to develop design details and perform supporting analyses to produce a Safety Case Report (SCR) for submittal to European Safety Authorities. The first part of Phase 2, hereafter referred as Phase 2A, started at the beginning of 1997 and will be completed at the end of 1998. Scope of this phase of the program is to develop the design modifications of important systems and structures so to comply with the

Full Text Available The correlation between the spectral peak photon energy, Ep, and the radiated energy or luminosity (i.e., the “Amati relation” and other correlations derived from it is one of the central and most debated topics in GRB astrophysics, with implications for physics and the geometry of prompt emission, the identification and understanding of various classes of GRBs (short/long, XRFs,sub-energetic, and GRB cosmology. Fermi is exceptionally suited to provide, also in conjunction with Swift observations, a significant step forward in this field of research. Indeed, one of the main goals of Fermi/GBM is to make accurate measurements of Ep, by exploiting its unprecedented broad energy band from ~8 keV to ~30MeV; in addition, for a small fraction of GRBs, the LAT can extend the spectral measurements up to the GeV energy range, thus allowing a reliable estimate of the bolometric radiated energy/luminosity. We provide a review, an update and a discussion of the impact of Fermi observations in the investigation, understanding and testing of the Ep,i –Eiso (“Amati” relation.

EP4 as a Therapeutic Target for Aggressive Human Breast Cancer

2018-03-01

Full Text Available G-protein-coupled receptors (GPCRs, also called seven-transmembrane or heptahelical receptors are a superfamily of cell surface receptor proteins that bind to many extracellular ligands and transmit signals to an intracellular guanine nucleotide-binding protein (G-protein. When a ligand binds, the receptor activates the attached G-protein by causing the exchange of Guanosine-5′-triphosphate (GTP for guanosine diphosphate (GDP. They play a major role in many physiological functions, as well as in the pathology of many diseases, including cancer progression and metastasis. Only a few GPCR members have been exploited as targets for developing drugs with therapeutic benefit in cancer. Present review briefly summarizes the signaling pathways utilized by the EP (prostaglandin E receptor family of GPCR, their physiological and pathological roles in carcinogenesis, with special emphasis on the roles of EP4 in breast cancer progression. We make a case for EP4 as a promising newer therapeutic target for treating breast cancer. We show that an aberrant over-expression of cyclooxygenase (COX-2, which is an inflammation-associated enzyme, occurring in 40–50% of breast cancer patients leads to tumor progression and metastasis due to multiple cellular events resulting from an increased prostaglandin (PG E2 production in the tumor milieu. They include inactivation of host anti-tumor immune cells, such as Natural Killer (NK and T cells, increased immuno-suppressor function of tumor-associated macrophages, promotion of tumor cell migration, invasiveness and tumor-associated angiogenesis, due to upregulation of multiple angiogenic factors including Vascular Endothelial Growth Factor (VEGF-A, increased lymphangiogenesis (due to upregulation of VEGF-C/D, and a stimulation of stem-like cell (SLC phenotype in cancer cells. All of these events were primarily mediated by activation of the Prostaglandin (PG E receptor EP4 on tumor or host cells. We show that

Full Text Available We compare the GLAMEPS system, a pan-European limited area ensemble prediction system, with ECMWF's EPS over Belgium for an extended period from March 2010 until the end of December 2010. In agreement with a previous study, we find GLAMEPS scores considerably better than ECMWF's EPS. To compute the economic value, we introduce a new relative economic value score for continuous forecasts. The added value of combining the GLAMEPS system with the LAEF system over Belgium is studied. We conclude that adding LAEF to GLAMEPS increases the value, although the increase is small compared to the improvement of GLAMEPS to ECMWF's EPS. As an added benefit we find that the combined GLAMEPS-LAEF multi-EPS system is more robust, that is, it is less vulnerable to the (accidental removal of one of its components.

2012-01-01

The epithelial cell adhesion molecule (EpCAM) has been shown to be overexpressed in breast cancer and stem cells and has emerged as an attractive target for immunotherapy of breast cancer patients. This study analyzes the effects of EpCAM on breast cancer cell lines with epithelial or mesenchymal phenotype. For this purpose, shRNA-mediated knockdown of EpCAM gene expression was performed in EpCAM high breast cancer cell lines with epithelial phenotype (MCF-7, T47D and SkBR3). Moreover, EpCAM low breast carcinoma cell lines with mesenchymal phenotype (MDA-MB-231, Hs578t) and inducible overexpression of EpCAM were used to study effects on proliferation, migration and in vivo growth. In comparison to non-specific silencing controls (n/s-crtl) knockdown of EpCAM (E#2) in EpCAM high cell lines resulted in reduced cell proliferation under serum-reduced culture conditions. Moreover, DNA synthesis under 3D culture conditions in collagen was significantly reduced. Xenografts of MCF-7 and T47D cells with knockdown of EpCAM formed smaller tumors that were less invasive. EpCAM low cell lines with tetracycline-inducible overexpression of EpCAM showed no increased cell proliferation or migration under serum-reduced growth conditions. MDA-MB-231 xenografts with EpCAM overexpression showed reduced invasion into host tissue and more infiltrates of chicken granulocytes. The role of EpCAM in breast cancer strongly depends on the epithelial or mesenchymal phenotype of tumor cells. Cancer cells with epithelial phenotype need EpCAM as a growth- and invasion-promoting factor, whereas tumor cells with a mesenchymal phenotype are independent of EpCAM in invasion processes and tumor progression. These findings might have clinical implications for EpCAM-based targeting strategies in patients with invasive breast cancer

Full Text Available The problem in this study is whether there is a positive influence of CFPS and EPS before and after restatement in giving positive impact on stock returns. The sample used in EPS before and after the restatement, while as many as 102 samples meanwhile CFPS before and after restatement using 82 sample companies listed on the Stock Exchange. Independent variables used in this study are the earnings per share and cash flow per share and the dependent variables used in this study is the stock return. Test equipment used in this study using multiple regression statistical model           The results of this study demonstrate that EPS before restatement did not impact significantly on the stock returns which indicates that investors have been aware that there is signal to improve the EPS before the restatement. EPS after restatement had no significant effect on return, this indicates that the new information is in accordance with the Market Efficiency hypothesis is that will make the market participants to react and take action to respond that new information. CFPS before and after restatement also had no significant effect on stock returns because investors do not use operating cash flow information as a basic for investment decisions. This can have implications on investors who use financial statements to make right decisions on the location of their assets in the companies that perform restatement as well for the company itself that financial report restatement can be made if it is seen as a form of commitment and sense of responsibility to the market to provide trustable information

The depressive conditions that affect women in the postpartum period are very relevant, either due to its high prevalence or to the impairment in the woman's quality of life, her fetus' and other components of her family. The multidisciplinary approach of these patients can significantly contribute to the early diagnosis and therapeutic treatment; avoiding that mild frames develop into serious situations as puerperal psychosis. The harmonic performance of the team formed by the obstetrician, pediatrician, psychiatrist, nurse and psychologist will be fundamental to reduce the impact of situations of postpartum depression (PPD. It is up to the obstetrician to suspect those women who have risk factors for developing PPD, according to their personal and familiar history. The obstetrician, pediatrician, or other partners of the health care team will be observing the patient's puerperal period whereas investigating suspicious situations of PPD, by using objective diagnosis methods. The psychologists are responsible for defining the final diagnosis and psychotherapy and they are an important part in the preparation of pregnant women during prenatal care for patients at risk of PPD. Precocious diagnosis will provide referral for combined services with the psychologist, treating and elucidating the patient about the PPD's condition.

1989-12-01

Is the clinical psychologist best characterized as a scientist-practitioner? Or does the practice of science and psychotherapy involve metaphysics to such an extent that the clinical psychologist ought to be considered a metaphysician-scientist-practitioner? To answer these questions, the roles, if any, of metaphysics in science and psychotherapy are examined. This article investigates this question by examining the views of the logical positivists, Karl Popper and Imre Lakatos, and concludes that the practice of science and psychotherapy involves metaphysics in (a) problem choice, (b) research and therapy design, (c) observation statements, (d) resolving the Duhemian problem, and (e) modifying hypotheses to encompass anomalous results.

The mechanism(s) responsible for the breakdown (nanoporation) of cell plasma membranes after nanosecond pulse (nsEP) exposure remains poorly understood. Current theories focus exclusively on the electrical field, citing electrostriction, water dipole alignment and/or electrodeformation as the primary mechanisms for pore formation. However, the delivery of a high-voltage nsEP to cells by tungsten electrodes creates a multitude of biophysical phenomena, including electrohydraulic cavitation, electrochemical interactions, thermoelastic expansion, and others. To date, very limited research has investigated non-electric phenomena occurring during nsEP exposures and their potential effect on cell nanoporation. Of primary interest is the production of acoustic shock waves during nsEP exposure, as it is known that acoustic shock waves can cause membrane poration (sonoporation). Based on these observations, our group characterized the acoustic pressure transients generated by nsEP and determined if such transients played any role in nanoporation. In this paper, we show that nsEP exposures, equivalent to those used in cellular studies, are capable of generating high-frequency (2.5 MHz), high-intensity (>13 kPa) pressure transients. Using confocal microscopy to measure cell uptake of YO-PRO®-1 (indicator of nanoporation of the plasma membrane) and changing the electrode geometry, we determined that acoustic waves alone are not responsible for poration of the membrane.

Abstract Six randomized clinical trials have been implemented to examine the efficacy of tenofovir disoproxil fumarate (TDF) and/or TDF/emtricitabine (TDF/FTC) as preexposure prophylaxis for HIV-1 infection (PrEP). Although largely complementary, the six trials have many similar features. As the earliest results become available, an urgent question may arise regarding whether changes should be made in the conduct of the other trials. To consider this in advance, a Consultation on the Implications of HIV Pre-Exposure Prophylaxis (PrEP) Trials Results sponsored by the Division of AIDS (DAIDS) of the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH), and the Bill and Melinda Gates Foundation (BMGF) was held on January 29, 2010, at the Natcher Conference Center, NIH, Bethesda, MD. Participants included basic scientists, clinical researchers (including investigators performing the current PrEP trials), and representatives from the U.S. Food and Drug Administration (FDA) and the agencies sponsoring the trials: the U.S. Centers for Disease Control and Prevention (CDC), the U.S. Agency for International Development (USAID), the BMGF, and the U.S. NIH. We report here a summary of the presentations and highlights of salient discussion topics from this workshop. PMID:20969483

Ethical Considerations for Psychologists Taking a Public Stance on Controversial Issues: The Balance Between Personal and Professional Life.

2014-07-01

Previous literature has documented the general issues psychologists often face while balancing their personal and professional lives. The struggle stems from attempting to satisfy the need to maintain a life outside of work while having the professional obligation to follow the American Psychological Association's (APA's) Ethical Principles of Psychologists and Code of Conduct (Ethics Code) to prevent their personal lives from interfering with their professional roles and relationships. The present paper analyzes the subject of psychologists taking a public position on controversial public issues. Although the APA Ethics Code does not restrict how psychologists conduct themselves during their personal time, taking a public stance on a controversial issue could potentially strain professional relationships and inadvertently reflect negatively on the profession. The present paper examines ethical issues that a) should be taken into account before psychologists take a public position on a controversial issue, and b) are in conflict with APA's Ethics Code or current research.

1990-12-01

We study electroweak production of heavy quarks - charm, beauty, and top - in deep inelastic electron-proton collisions at the proposed LEP+LHC collider at CERN. The assumed energy for the collisions is E e =50 GeV, E p =8000 GeV, providing an ep center of mass energy, √s≅1.26 TeV. We invoke the boson-gluon fusion model to estimate theoretical cross sections and distributions for the heavy quarks. Higher order QCD corrections are only approximately taken into account, by assuming a (normalization) K-factor of 2 for the charm and beauty quark production rates and incorporating the parton shower cascades. With these assumptions and the parameterization of Eichten et al. for the structure functions (EHLQ, set 1), we find the following cross sections: σ(ep→c+X)≅O(3 μb), σ(ep→b+X)≅O(40 nb), and σ(ep→t+X)≅4 pb for m t =120 GeV, decreasing to 0.5 pb for m t =250 GeV. These cross sections would provide O(6x10 9 ) charmed hadrons, O(8x10 7 ) beauty hadrons, and O(10 3 ) top hadrons, for an integrated ep luminosity of 1000 pb -1 . The heavy quark rates in ep collisions are considerably smaller than the corresponding rates in pp collisions at LHC, with √s=16 TeV. This gives a clear advantage to pp collisions for top searches. However, for the charmed and beauty quarks only a tiny fraction of the cross sections in p+p→Q+X can be triggered in comparison to the corresponding cross sections in e+p→Q+X, resulting in comparable number of measured heavy quark events in the ep and pp mode. We sketch the energy-momentum profile of heavy quark events in ep collisions and illustrate the kind of analyses that experiments at the LEP+LHC collider would undertake to quantitatively study heavy quark physics. In particular, prospects of measuring the particle-antiparticle mixing parameter x s =ΔM/Γ for the B s 0 -anti B s 0 meson system are evaluated, and search strategies for the top quark in ep collisions are presented.

Evaluation of resection margins during cancer surgery can be challenging, often resulting in incomplete tumour removal. Fluorescence-guided surgery (FGS) aims to aid the surgeon to visualize tumours and resection margins during surgery. FGS relies on a clinically applicable imaging system in combination with a specific tumour-targeting contrast agent. In this study EpCAM (epithelial cell adhesion molecule) is evaluated as target for FGS in combination with the novel Artemis imaging system. The NIR fluorophore IRDye800CW was conjugated to the well-established EpCAM specific monoclonal antibody 323/A3 and an isotype IgG1 as control. The anti-EpCAM/800CW conjugate was stable in serum and showed preserved binding capacity as evaluated on EpCAM positive and negative cell lines, using flow cytometry and cell-based plate assays. Four clinically relevant orthotopic tumour models, i.e. colorectal cancer, breast cancer, head and neck cancer, and peritonitis carcinomatosa, were used to evaluate the performance of the anti-EpCAM agent with the clinically validated Artemis imaging system. The Pearl Impulse small animal imaging system was used as reference. The specificity of the NIRF signal was confirmed using bioluminescence imaging and green-fluorescent protein. All tumour types could clearly be delineated and resected 72 h after injection of the imaging agent. Using NIRF imaging millimetre sized tumour nodules were detected that were invisible for the naked eye. Fluorescence microscopy demonstrated the distribution and tumour specificity of the anti-EpCAM agent. This study shows the potential of an EpCAM specific NIR-fluorescent agent in combination with a clinically validated intraoperative imaging system to visualize various tumours during surgery

A measurement of the inclusive deep-inelastic neutral current e+p scattering cross section is reported in the region of four-momentum transfer squared, 12<=Q^2<=150 GeV^2, and Bjorken x, 2x10^-4<=x<=0.1. The results are based on data collected by the H1 Collaboration at the ep collider HERA at positron and proton beam energies of E_e=27.6 GeV and E_p=920 GeV, respectively. The data are combined with previously published data, taken at E_p=820 GeV. The accuracy of the combined measurement is typically in the range of 1.3-2%. A QCD analysis at next-to-leading order is performed to determine the parton distributions in the proton based on H1 data.

Merkel cell polyomavirus recruits MYCL to the EP400 complex to promote oncogenesis.

2017-10-01

Full Text Available Merkel cell carcinoma (MCC frequently contains integrated copies of Merkel cell polyomavirus DNA that express a truncated form of Large T antigen (LT and an intact Small T antigen (ST. While LT binds RB and inactivates its tumor suppressor function, it is less clear how ST contributes to MCC tumorigenesis. Here we show that ST binds specifically to the MYC homolog MYCL (L-MYC and recruits it to the 15-component EP400 histone acetyltransferase and chromatin remodeling complex. We performed a large-scale immunoprecipitation for ST and identified co-precipitating proteins by mass spectrometry. In addition to protein phosphatase 2A (PP2A subunits, we identified MYCL and its heterodimeric partner MAX plus the EP400 complex. Immunoprecipitation for MAX and EP400 complex components confirmed their association with ST. We determined that the ST-MYCL-EP400 complex binds together to specific gene promoters and activates their expression by integrating chromatin immunoprecipitation with sequencing (ChIP-seq and RNA-seq. MYCL and EP400 were required for maintenance of cell viability and cooperated with ST to promote gene expression in MCC cell lines. A genome-wide CRISPR-Cas9 screen confirmed the requirement for MYCL and EP400 in MCPyV-positive MCC cell lines. We demonstrate that ST can activate gene expression in a EP400 and MYCL dependent manner and this activity contributes to cellular transformation and generation of induced pluripotent stem cells.

Endometriosis is a debilitating, estrogen-dependent, progesterone-resistant, inflammatory gynecological disease of reproductive age women. Two major clinical symptoms of endometriosis are chronic intolerable pelvic pain and subfertility or infertility, which profoundly affect the quality of life in women. Current hormonal therapies to induce a hypoestrogenic state are unsuccessful because of undesirable side effects, reproductive health concerns, and failure to prevent recurrence of disease. There is a fundamental need to identify nonestrogen or nonsteroidal targets for the treatment of endometriosis. Peritoneal fluid concentrations of prostaglandin E2 (PGE2) are higher in women with endometriosis, and this increased PGE2 plays important role in survival and growth of endometriosis lesions. The objective of the present study was to determine the effects of pharmacological inhibition of PGE2 receptors, EP2 and EP4, on molecular and cellular aspects of the pathogenesis of endometriosis and associated clinical symptoms. Using human fluorescent endometriotic cell lines and chimeric mouse model as preclinical testing platform, our results, to our knowledge for the first time, indicate that selective inhibition of EP2/EP4: (i) decreases growth and survival of endometriosis lesions; (ii) decreases angiogenesis and innervation of endometriosis lesions; (iii) suppresses proinflammatory state of dorsal root ganglia neurons to decrease pelvic pain; (iv) decreases proinflammatory, estrogen-dominant, and progesterone-resistant molecular environment of the endometrium and endometriosis lesions; and (v) restores endometrial functional receptivity through multiple mechanisms. Our novel findings provide a molecular and preclinical basis to formulate long-term nonestrogen or nonsteroidal therapy for endometriosis. PMID:26199416

Modeling Bacteria-Water Interactions in Soil: EPS Dynamics Under Evaporative Conditions

The soil habitat represents a major linkage between the water and carbon cycles: the ability of soils to sequester or release carbon is determined primarily by soil moisture. Water retention and distribution in soils controls the abundance and activity of soil microbes. Microbes in turn impact water retention by creating biofilms, composed of extracellular polymeric substances (EPS). We model the effects of bacterial EPS on water retention at the pore scale. We use the lattice Boltzmann method (LBM), a well-established fluid dynamics modeling platform, and modify it to include the effects of water uptake and release by the swelling/shrinking EPS phase. The LB model is implemented in 2-D, with a non-ideal gas equation of state that allows condensation and evaporation of fluid in pore spaces. Soil particles are modeled according to experimentally determined particle size distributions and include realistic pore geometries, in contrast to many soil models which use spherical soil particles for simplicity. Model results are compared with evaporation experiments in soil micromodels and other simpler experimental systems, and model parameters are tuned to match experimental results. Drying behavior and solid-gel contact angle of EPS produced by the soil bacteria Sinorhizobium meliloti has been characterized and compared to the behavior of deionized water under the same conditions. The difference in behavior between the fluids is used to parameterize the model. The model shows excellent qualitative agreement for soil micromodels with both aggregated and non-aggregated particle arrangements under no-EPS conditions, and reproduces realistic drying behavior for EPS. This work represents a multi-disciplinary approach to understanding microbe-soil interactions at the pore scale.

Full Text Available organizational-professional conflict occurs among employees in situations when organizational expectations and demands are opposed to the professional principles and standards. The results of studies have shown that this conflict negatively affects employees' attitude towards the job and affective-motivational state of fulfilment with work role. The purpose of this research was to examine exposure to organizational-professional conflict among I/O psychologists in Serbia, to find out whether there is a correlation between the exposure to organizational-professional conflict, job satisfaction and work engagement, and to determine the main factors of exposure to organizational-professional conflict. Our sample consisted of 96 I/O psychologists. Results have shown that there was significant high negative correlation between the exposure to organizational-professional conflict and job satisfaction, as well as significant moderate negative correlation between the exposure to organizational-professional conflict and work engagement. The highest correlations were with social dimensions of job satisfaction. The exposure to organizational-professional conflict was lower among I/O psychologists with longer work experience and those at higher positions in organizational hierarchy. The exposure to organizational-professional conflict was higher among I/O psychologists who were working in privately owned companies and among those who were fixed-term employees. There was no significant correlation between the exposure to organizational-professional conflict and the size of the organization or business field. Our study showed that organizational-professional conflict should be considered as an important theoretical and research topic, as well as a relevant professional and career issue.

The EUMETSAT Polar System (EPS) will be followed by a second generation system called EPS-SG. This new family of missions will contribute to the Joint Polar System being jointly set up with NOAA in the timeframe 2020-2040. These satellites will fly, like Metop (EPS), in a sun synchronous, low earth orbit at 830 km altitude and 09:30 local time descending node, providing observations over the full globe with revisit times of 12 hours. EPS-SG consists of two different satellites configurations, the EPS-SGa series dedicated to IR and MW sounding, and the EPS-SGb series dedicated to microwave imaging and scatterometry. The EPS-SG family will consist of three successive launches of each satellite-type. The Microwave Imager (MWI) will be hosted on Metop-SGb series of satellites, with the primary objective of supporting Numerical Weather Prediction (NWP) at regional and global scales. Other applications will be observation of surface parameters such as sea ice concentration and hydrology applications. The 18 MWI instrument frequencies range from 18.7 GHz to 183 GHz. All MWI channels up to 89 GHz will measure V- and H polarizations. The MWI was also designed to provide continuity of measurements for select heritage microwave imager channels (e.g. SSM/I, AMSR-E). The additional sounding channels such as the 50-55 and 118 GHz bands will provide additional cloud and precipitation information over sea and land. This combination of channels was successfully tested on the NPOESS Aircraft Sounder Testbed - Microwave Sounder (NAST-M) airborne radiometer, and it is the first time that will be implemented in a conical scanning configuration in a single instrument. An overview of the EPS-SG programme and the MWI instrument will be presented.

The utiquity and many roles of exopolymers (EPS in aquatic systems

Directory of Open Access Journals (Sweden)

Roger S. Wotton

Full Text Available Exopolymers (EPS are produced by unicellular and multicellular organisms. They consist largely of polysaccharides that hydrate rapidly on contact with water and link to form gels. EPS have many uses: in attachment; in locomotion on substrata; as a protection against predators, pathogens and changes in physico-chemical conditions; as a means of overcoming the threat of desiccation; in preventing abrasion; and in feeding. When free of organisms, some EPS form loosely associated polymer gels that are important in the development of organic matter aggregates. These aggregates, together with mucus-bound faecal pellets, play an essential role in nutrient cycling, and in the metabolism of ecosystems.;

Prostaglandin E2 (PGE2) receptor 3 (EP3) regulates tumor cell proliferation, migration, and invasion in numerous cancers. The role of EP3 as a prognostic biomarker in endometrial cancer remains unclear. The primary aim of this study was to analyze the prognostic significance of EP3 expression in endometrial cancer. We analyzed the EP3 expression of 140 endometrial carcinoma patients by immunohistochemistry. RL95-2 endometrial cancer cell line was chosen from four endometrial cancer cell lines (RL95-2, Ishikawa, HEC-1-A, and HEC-1-B) according to EP3 expression level. Treated with PGE2 and EP3 antagonist, RL95-2 cells were investigated by MTT, BrdU, and wound healing assay for functional assessment of EP3. EP3 staining differed significantly according to WHO tumor grading in both whole cohort (p = 0.01) and the subgroup of endometrioid carcinoma (p = 0.01). Patients with high EP3 expression in their respective tumors had impaired progression-free survival as well as overall survival in both cohorts above. EP3 expression in the overall cohort was identified as an independent prognostic marker for progression-free survival (HR 1.014, 95%CI 1.003-1.024, p = 0.01) when adjusted for age, stage, grading, and recurrence. Treatment with EP3 antagonists induced upregulation of estrogen receptor β and decreased activity of Ras and led to attenuated proliferation and migration of RL95-2 cells. EP3 seems to play a crucial role in endometrial cancer progression. In the context of limited systemic treatment options for endometrial cancer, this explorative analysis identifies EP3 as a potential target for diagnostic workup and therapy.

Several genetic mutations affecting the development and function of mammalian hair cells have been shown to cause deafness but not vestibular defects, most likely because vestibular deficits are sometimes centrally compensated. The study of hair cell physiology is thus a powerful direct approach to ascertain the functional status of the vestibular end organs. Deletion of Epidermal growth factor receptor pathway substrate 8 (Eps8), a gene involved in actin remodeling, has been shown to cause deafness in mice. While both inner and outer hair cells from Eps8 knockout (KO) mice showed abnormally short stereocilia, inner hair cells (IHCs) also failed to acquire mature-type ion channels. Despite the fact that Eps8 is also expressed in vestibular hair cells, Eps8 KO mice show no vestibular deficits. In the present study we have investigated the properties of vestibular Type I and Type II hair cells in Eps8-KO mice and compared them to those of cochlear IHCs. In the absence of Eps8, vestibular hair cells show normally long kinocilia, significantly shorter stereocilia and a normal pattern of basolateral voltage-dependent ion channels. We have also found that while vestibular hair cells from Eps8 KO mice show normal voltage responses to injected sinusoidal currents, which were used to mimic the mechanoelectrical transducer current, IHCs lose their ability to synchronize their responses to the stimulus. We conclude that the absence of Eps8 produces a weaker phenotype in vestibular hair cells compared to cochlear IHCs, since it affects the hair bundle morphology but not the basolateral membrane currents. This difference is likely to explain the absence of obvious vestibular dysfunction in Eps8 KO mice. Copyright © 2016 IBRO. Published by Elsevier Ltd. All rights reserved.

Immunohistochemical analysis based Ep-ICD subcellular localization index (ESLI) is a novel marker for metastatic papillary thyroid microcarcinoma

International Nuclear Information System (INIS)

2012-01-01

Thyroid cancer is among the fastest growing malignancies; almost fifty-percent of these rapidly increasing incidence tumors are less than or equal to 1cm in size, termed papillary thyroid microcarcinoma (PTMC). The management of PTMC remains a controversy due to differing natural history of these patients. Epithelial cell adhesion molecule (EpCAM) is comprised of an extracellular domain (EpEx), a single transmembrane domain and an intracellular domain (Ep-ICD). Our group reported nuclear Ep-ICD correlated with poor prognosis in thyroid cancer (Ralhan et al., BMC Cancer 2010,10:331). Here in, we hypothesized nuclear and cytoplasmic accumulation of Ep-ICD and loss of membranous EpEx may aid in distinguishing metastatic from non-metastatic PTMC, which is an important current clinical challenge. To test our hypothesis, Ep-ICD and EpEx expression levels were analyzed in PTMC and the staining was correlated with metastatic potential of these carcinomas. Thirty-six PTMC patients (tumor size 0.5 - 1cm; metastatic 8 cases and non-metastatic 28 cases) who underwent total thyroidectomy were selected. The metastatic group consisted of patients who developed lymph node or distant metastasis at diagnosis or during follow up. The patients’ tissues were stained for Ep-ICD and EpEx using domain specific antibodies by immunohistochemistry and evaluated. PTMC patients with metastasis had higher scores for nuclear and cytoplasmic Ep-ICD immunostaining than the patients without metastasis (1.96 ± 0.86 vs. 1.22 ± 0.45; p = 0.007 and 5.37 ± 0.33 vs. 4.72 ± 1.07; p = 0.016, respectively). Concomitantly, the former had lower scores for membrane EpEx than the non-metastatic group (4.64 ± 1.08 vs. 5.64 ± 1.51; p = 0.026). An index of aggressiveness, Ep-ICD subcellular localization index (ESLI), was defined as sum of the IHC scores for accumulation of nuclear and cytoplasmic Ep-ICD and loss of membranous EpEx; ESLI = [Ep − ICD nuc + Ep − ICD cyt + loss of membranous EpEx].

Objective To compare the value and effectiveness of different prioritization strategies of pre-exposure prophylaxis (PrEP) in New York City (NYC). Design Mathematical modeling utilized as clinical trial is not feasible. Methods Using a model accounting for both sexual and parenteral transmission of HIV we compare different prioritization strategies (PPS) for PrEP to two scenarios—no PrEP and PrEP for all susceptible at-risk individuals. The PPS included PrEP for all MSM, only high-risk MSM, high-risk heterosexuals, and injection drug users, and all combinations of these four strategies. Outcomes included HIV infections averted, and incremental cost effectiveness (per-infection averted) ratios. Initial assumptions regarding PrEP included a 44% reduction in HIV transmission, 50% uptake in the prioritized population and an annual cost per person of $9,762. Sensitivity analyses on key parameters were conducted. Results Prioritization to all MSM results in a 19% reduction in new HIV infections. Compared to PrEP for all persons at-risk this PPS retains 79% of the preventative effect at 15% of the total cost. PrEP prioritized to only high-risk MSM results in a reduction in new HIV infections of 15%. This PPS retains 60% of the preventative effect at 6% of the total cost. There are diminishing returns when PrEP utilization is expanded beyond this group. Conclusions PrEP implementation is relatively cost-inefficient under our initial assumptions. Our results suggest that PrEP should first be promoted among MSM who are at particularly high-risk of HIV acquisition. Further expansion beyond this group may be cost-effective, but is unlikely to be cost-saving. PMID:25493594

"God save us from psychologists as expert witnesses": the battle for forensic psychology in early twentieth-century Germany.

Science.gov (United States)

Wolffram, Heather

2015-11-01

This article is focused on the jurisdictional battle between psychiatrists and psychologists over psychological expertise in legal contexts that took place during the first decades of the 20th century. Using, as an example, the debate between the psychologist William Stern, the psychiatrist Albert Moll, and the jurist Albert Hellwig, which occurred at the International Congress for Sexual Research held in Berlin in 1926, it aims to demonstrate the manner in which psychiatrists' responses to psychologists' attempts to gain admittance to Germany's courtrooms were shaped not only by epistemological and methodological objections, but also by changes to expert witnessing that had already encroached on psychiatrists' professional territory. Building upon recent work examining the relationship between psychologists and jurists prior to the First World War, this article also seeks to examine the role of judges and lawyers in the contest over forensic psychology in the mid-1920s, arguing that they ultimately became referees in the increasingly public disputes between psychiatrists and psychologists.

The HIV epidemic among Black men and transgender women who have sex with men (BMTW) demands an urgent public health response. HIV point prevalence among this population ranges from 25 to 43%-a rate far exceeding any other group. Pre-exposure prophylaxis (PrEP) for HIV prevention is a very promising prevention tool; however, its full potential to slow the epidemic has yet to be realized. For the current study, random time-location sampling at Black Gay Pride Events was used to collect data from N = 1274 BMTW, from five US cities, reporting HIV-negative/unknown status. In-field HIV testing was also provided to participants. Participants were assessed on awareness and use of PrEP, health care factors, HIV testing history, psychosocial variables, and sex behaviors. About one third of participants were aware of PrEP (39%), and a small percentage of participants were users of PrEP (4.6%). In multivariable analyses, being in a relationship, testing for HIV in the past 6 months, and others being aware of one's sexuality were positively associated with PrEP awareness. Higher levels of internalized homophobia and greater numbers of female sex partners were positively associated with PrEP use, while education and condom use were negatively associated. Based on study findings, messaging and uptake of PrEP needs greater expansion and requires novel approaches for scale-up. Improving linkage to HIV testing services is likely critical for engaging BMTW with PrEP. The potential for PrEP to slow the HIV epidemic is high; however, we must strengthen efforts to ensure universal availability and uptake.

This paper deals with the extracellular polymeric substance (EPS) of Proteus mirabilis TJ-1 used as a novel biosorbent to remove dye from aqueous solution in batch systems. As a widely used and hazardous dye, basic blue 54 (BB54) was chosen as the model dye to examine the adsorption performance of the EPS. The effects of pH, initial dye concentration, contact time and temperature on the sorption of BB54 to the EPS were examined. At various initial dye concentrations (50-400 mg/L), the batch sorption equilibrium can be obtained in only 5 min. Kinetic studies suggested that the sorption followed the internal transport mechanism. According to the Langmuir model, the maximum BB54 uptake of 2.005 g/g was obtained. Chemical analysis of the EPS indicated the presence of protein (30.9%, w/w) and acid polysaccharide (63.1%, w/w). Scanning electron microscopy (SEM) images showed that the EPS with a crystal-linear structure was whole enwrapped by adsorbed dye molecules. FTIR spectrum result revealed the presence of adsorbing groups such as carboxyl, hydroxyl and amino groups in the EPS. High-molecular weight of the EPS with more binding-sites and stronger van der Waals forces together with its specific construct leads to the excellent performance of dye adsorption. The EPS shows potential board application as a biosorbent for both environmental protection and dye recovery.

Proneoplastic effects of PGE2 mediated by EP4 receptor in colorectal cancer.

LENUS (Irish Health Repository)

Doherty, Glen A

2009-01-01

BACKGROUND: Prostaglandin E2 (PGE2) is the major product of Cyclooxygenase-2 (COX-2) in colorectal cancer (CRC). We aimed to assess PGE2 cell surface receptors (EP 1-4) to examine the mechanisms by which PGE2 regulates tumour progression. METHODS: Gene expression studies were performed by quantitative RT-PCR. Cell cycle was analysed by flow cytometry with cell proliferation quantified by BrdU incorporation measured by enzyme immunoassay. Immunohistochemistry was employed for expression studies on formalin fixed paraffin embedded tumour tissue. RESULTS: EP4 was the most abundant subtype of PGE2 receptor in HT-29 and HCA7 cells (which show COX-2 dependent PGE2 generation) and was consistently the most abundant transcript in human colorectal tumours (n = 8) by qRT-PCR (ANOVA, p = 0.01). G0\\/G1 cell cycle arrest was observed in HT-29 cells treated with SC-236 5 microM (selective COX-2 inhibitor) for 24 hours (p = 0.02), an effect abrogated by co-incubation with PGE2 (1 microM). G0\\/G1 arrest was also seen with a specific EP4 receptor antagonist (EP4A, L-161982) (p = 0.01). Treatment of HT-29 cells with either SC-236 or EP4A caused reduction in intracellular cAMP (ANOVA, p = 0.01). Early induction in p21WAF1\\/CIP1 expression (by qRT-PCR) was seen with EP4A treatment (mean fold increase 4.4, p = 0.04) while other genes remained unchanged. Similar induction in p21WAF1\\/CIP1 was also seen with PD153025 (1 microM), an EGFR tyrosine kinase inhibitor, suggesting EGFR transactivation by EP4 as a potential mechanism. Additive inhibition of HCA7 proliferation was observed with the combination of SC-236 and neutralising antibody to amphiregulin (AR), a soluble EGFR ligand. Concordance in COX-2 and AR localisation in human colorectal tumours was noted. CONCLUSION: COX-2 regulates cell cycle transition via EP4 receptor and altered p21WAF1\\/CIP1 expression. EGFR pathways appear important. Specific targeting of the EP4 receptor or downstream targets may offer a safer alternative

Transgender women may face a disparate risk for HIV/AIDS compared to other groups. In 2012, Truvada was approved for daily use as HIV pre-exposure prophylaxis (PrEP). However, there is a dearth of research about barriers and facilitators to PrEP in transgender women. This paper will shed light on transgender women living in New York City's perceived and actual challenges to using PrEP and potential strategies to overcome them. After completing an initial screening process, four 90-min focus groups were completed with n = 18 transgender women. Participants were asked what they like and dislike about PrEP. Participants identified the following barriers: uncomfortable side effects, difficulty taking pills, stigma, exclusion of transgender women in advertising, and lack of research on transgender women and PrEP. Facilitators included: reducing pill size, increasing the types of available HIV prevention products, and conducting scientific studies to evaluate PrEP in transgender women.

Psychologists experience of cognitive behaviour therapy in a developing country: a qualitative study from Pakistan

Ayub Muhammad

2010-01-01

Full Text Available Abstract Background Psychological therapies especially Cognitive Behaviour Therapy (CBT are used widely in the West to help patients with psychiatric problems. Cognitive Behaviour Therapy has an established evidence base for the treatment of different emotional disorders. In spite of these developments in the developed world, patients in most developing countries hardly benefit from non pharmacological interventions. Although a significant number of psychologists are trained in Pakistan each year, psychological interventions play only a minor role in treatment plans in Pakistan. We conducted interviews with psychologists in Pakistan, to explore their experiences and their views on "providing CBT in Pakistan". These interviews were conducted as part of a project whose focus was to try to develop culturally-sensitive CBT in Pakistan. Methods In depth semi structured interviews were conducted with 5 psychologists working in psychiatry departments in Lahore, Pakistan. Results All the psychologists reported that psychotherapies, including CBT, need adjustments for use in Pakistan, although they were not able to elicit on these in details. Four major themes were discovered, hurdles in therapy, therapy related issues, involvement of the family and modification in therapy. The biggest hurdles in therapy were described to be service and resource issues. Conclusions For CBT to be acceptable, accessible and effective in Non Western cultures numerous adjustments need to be made, taking into consideration; factors related to service structure and delivery, patient's knowledge and beliefs about health and the therapy itself. Interviews with the psychologists in these countries can give us insights which can guide development of therapy and manuals to support its delivery.

This chapter presents a method called PolyA-iEP that has been developed for the prediction of polyadenylation sites. More precisely, PolyA-iEP is a method that recognizes mRNA 3'ends which contain polyadenylation sites. It is a modular system which consists of two main components. The first exploits the advantages of emerging patterns and the second is a distance-based scoring method. The outputs of the two components are finally combined by a classifier. The final results reach very high scores of sensitivity and specificity.

PrEP as a feature in the optimal landscape of combination HIV prevention in sub-Saharan Africa.

Science.gov (United States)

McGillen, Jessica B; Anderson, Sarah-Jane; Hallett, Timothy B

2016-01-01

The new WHO guidelines recommend offering pre-exposure prophylaxis (PrEP) to people who are at substantial risk of HIV infection. However, where PrEP should be prioritised, and for which population groups, remains an open question. The HIV landscape in sub-Saharan Africa features limited prevention resources, multiple options for achieving cost saving, and epidemic heterogeneity. This paper examines what role PrEP should play in optimal prevention in this complex and dynamic landscape. We use a model that was previously developed to capture subnational HIV transmission in sub-Saharan Africa. With this model, we can consider how prevention funds could be distributed across and within countries throughout sub-Saharan Africa to enable optimal HIV prevention (that is, avert the greatest number of infections for the lowest cost). Here, we focus on PrEP to elucidate where, and to whom, it would optimally be offered in portfolios of interventions (alongside voluntary medical male circumcision, treatment as prevention, and behaviour change communication). Over a range of continental expenditure levels, we use our model to explore prevention patterns that incorporate PrEP, exclude PrEP, or implement PrEP according to a fixed incidence threshold. At low-to-moderate levels of total prevention expenditure, we find that the optimal intervention portfolios would include PrEP in only a few regions and primarily for female sex workers (FSW). Prioritisation of PrEP would expand with increasing total expenditure, such that the optimal prevention portfolios would offer PrEP in more subnational regions and increasingly for men who have sex with men (MSM) and the lower incidence general population. The marginal benefit of including PrEP among the available interventions increases with overall expenditure by up to 14% (relative to excluding PrEP). The minimum baseline incidence for the optimal offer of PrEP declines for all population groups as expenditure increases. We find that using

Methane oxidation and formation of EPS in compost: effect of oxygen concentration

Oxygen concentration plays an important role in the regulation of methane oxidation and the microbial ecology of methanotrophs. However, this effect is still poorly quantified in soil and compost ecosystems. The effect of oxygen on the formation of exopolymeric substances (EPS) is as yet unknown. We studied the effect of oxygen on the evolution of methanotrophic activity. At both high and low oxygen concentrations, peak activity was observed twice within a period of 6 months. Phospholipid fatty acid analysis showed that there was a shift from type I to type II methanotrophs during this period. At high oxygen concentration, EPS production was about 250% of the amount at low oxygen concentration. It is hypothesized that EPS serves as a carbon cycling mechanism for type I methanotrophs when inorganic nitrogen is limiting. Simultaneously, EPS stimulates nitrogenase activity in type II methanotrophs by creating oxygen-depleted zones. The kinetic results were incorporated in a simulation model for gas transport and methane oxidation in a passively aerated biofilter. Comparison between the model and experimental data showed that, besides acting as a micro-scale diffusion barrier, EPS can act as a barrier to macro-scale diffusion, reducing the performance of such biofilters. - 1.5% oxygen resulted in a slightly higher and more stable methane oxidation activity

2018-02-21

Quality Improvement (QI) is a health care interprofessional team activity wherein psychology as a field and individual psychologists in health care settings can and should adopt a more robust presence. The current article makes the argument for why psychology's participation in QI is good for health care, is good for our profession, and is the right thing to do for the patients and families we serve. It reviews the varied ways individual psychologists and our profession can integrate quality processes and improve health care through: (1) our approach to our daily work; (2) our roles on health care teams and involvement in organizational initiatives; (3) opportunities for teaching and scholarship; and (4) system redesign and advocacy within our health care organizations and health care environment.

EP1000 passive plant description

International Nuclear Information System (INIS)

Saiu, G.

1999-01-01

In 1994, a group of European Utilities, together with Westinghouse and its Industrial Partner GENESI (an Italian consortium including ANSALDO and FIAT), initiated a program designated EPP (European Passive Plant) to evaluate Westinghouse Passive Nuclear Plant Technology for application in Europe. In Phase I of the European Passive Plant Program which was completed in 1996, a 1000 MWe passive plant reference design (EP1000) was established which conforms to the European Utility Requirements (EUR) and is expected to meet the European Safety Authorities requirements. Phase 2 of the program was initiated in 1997 with the objective of developing the Nuclear Island design details and performing supporting analyses to start development of Safety Case Report (SCR) for submittal to European Licensing Authorities. The first part of Phase 2, 'Design Definition' phase (Phase 2A) will be completed at the end of 1998, the main efforts being design definition of key systems and structures, development of the Nuclear Island layout, and performing preliminary safety analyses to support design efforts. The second part, 'Phase 2B', includes both the analyses and evaluations required to demonstrate the adequacy of the design, and to support the preparation of Safety Case Report. The second part of Phase 2 of the program will start at the beginning of 1999 and will be completed in the 2001. Incorporation of the EUR has been a key design requirement for the EP1000 from the beginning of the program. Detailed design solutions to meet the EUR have been defined and the safety approach has also been developed based on the EUR guidelines. This paper integrates and updates the plant description reported in the IAEA TECDOC-968. The most significant developments of the EP1000 plant design during Phase 2A of the EPP program are described and reference is made to the key design requirements set by the EUR Rev. B document.

We investigated message comprehension and message framing preferences for communicating about PrEP efficacy with US MSM. We conducted eight focus groups (n = 38) and n = 56 individual interviews with MSM in Providence, RI. Facilitators probed comprehension, credibility, and acceptability of efficacy messages, including percentages, non-numerical paraphrases, efficacy ranges versus point estimates, and success- versus failure-framed messages. Our findings indicated a range of comprehension and operational understandings of efficacy messages. Participants tended to prefer percentage-based and success-framed messages, although preferences varied for communicating about efficacy using a single percentage versus a range. Participants reported uncertainty about how to interpret numerical estimates, and many questioned whether trial results would predict personal effectiveness. These results suggest that providers and researchers implementing PrEP may face challenges in communicating with users about efficacy. Efforts to educate MSM about PrEP should incorporate percentage-based information, and message framing decisions may influence message credibility and overall PrEP acceptability.

Systemic EP4 Inhibition Increases Adhesion Formation in a Murine Model of Flexor Tendon Repair.

Directory of Open Access Journals (Sweden)

Full Text Available Flexor tendon injuries are a common clinical problem, and repairs are frequently complicated by post-operative adhesions forming between the tendon and surrounding soft tissue. Prostaglandin E2 and the EP4 receptor have been implicated in this process following tendon injury; thus, we hypothesized that inhibiting EP4 after tendon injury would attenuate adhesion formation. A model of flexor tendon laceration and repair was utilized in C57BL/6J female mice to evaluate the effects of EP4 inhibition on adhesion formation and matrix deposition during flexor tendon repair. Systemic EP4 antagonist or vehicle control was given by intraperitoneal injection during the late proliferative phase of healing, and outcomes were analyzed for range of motion, biomechanics, histology, and genetic changes. Repairs treated with an EP4 antagonist demonstrated significant decreases in range of motion with increased resistance to gliding within the first three weeks after injury, suggesting greater adhesion formation. Histologic analysis of the repair site revealed a more robust granulation zone in the EP4 antagonist treated repairs, with early polarization for type III collagen by picrosirius red staining, findings consistent with functional outcomes. RT-PCR analysis demonstrated accelerated peaks in F4/80 and type III collagen (Col3a1 expression in the antagonist group, along with decreases in type I collagen (Col1a1. Mmp9 expression was significantly increased after discontinuing the antagonist, consistent with its role in mediating adhesion formation. Mmp2, which contributes to repair site remodeling, increases steadily between 10 and 28 days post-repair in the EP4 antagonist group, consistent with the increased matrix and granulation zones requiring remodeling in these repairs. These findings suggest that systemic EP4 antagonism leads to increased adhesion formation and matrix deposition during flexor tendon healing. Counter to our hypothesis that EP4 antagonism

Men who have sex with men (MSM) continue to be disproportionately affected by HIV in Malaysia. Recent success has been observed within demonstration projects examining the efficacy of HIV pre-exposure prophylaxis (PrEP), an antiretroviral -based medication taken by HIV-negative men to prevent sero-conversion. In order for such promising findings to be translated in real-world settings, it is important to understand the acceptability of PrEP, including perceived barriers to access or uptake. As part of a larger mixed-methods study exploring acceptability and willingness to use PrEP among MSM in Malaysia, 19 men took part in audio-recorded focus group discussions hosted by a community-based HIV organization and facilitated by a trained researcher. Discussions focussed on awareness and potential information management, general perceptions of PrEP and potential motivations or barriers to the use of PrEP, including those at the personal, social, health system or structural level. Data were transcribed verbatim and underwent a detailed thematic analysis. Rather than perceiving PrEP as a replacement for condoms in terms of having safer sex, many participants viewed it as an additional layer protection, serving as a crucial barrier to infection on occasions where condom use was intended, but did not occur. It was also perceived as more valuable to "at-risk" men, such as those in HIV sero-discordant relationships or those with a higher number of sexual partners. Elements of discussion tended to suggest that some men taking PrEP may be subject to stigma from others, on the assumption they may be promiscuous or engage in high-risk sexual behaviours. This qualitative study indicates that, broadly speaking, PrEP may be acceptable to MSM in Malaysia. However, in order for its potential to be realized, and uptake achieved, educative interventions are required to inform the target population as to the efficacy and potential, positive impact of PrEP. Given concerns for how those

Full Text Available In the current study we aimed to clarify the potential of EpCAM and villin as in vivo biomarkers for both Barrett esophagus (BE-associated neoplasia and BE versus cardiac mucosa. Immunohistochemical staining in BE with various degrees of intraepithelial neoplasia (IN, Barrett carcinoma (BC and in normal cardiac mucosa (CM revealed a lack of EpCam and villin in squamous esophageal epithelium. All specimens of IN and BC showed EpCam with varying staining intensities. In 57% of CM samples a weak signal was detected; the remainder displayed strong EpCam expression. Villin was found in 97% of BE specimens and in all those with IN; 37% of BC and 75% of CM specimens were also positive. We conclude that expression of EpCam and villin differs only between squamous epithelium and BE. Determination of these proteins does not allow discrimination between different degrees of neoplasia or between esophageal intestinal metaplasia and cardiac mucosa.

Identification of patients with oral dysplasia at high risk of cancer development and oral squamous cell carcinoma (OSCC) at increased risk of disease recurrence will enable rigorous personalized treatment. Regulated intramembranous proteolysis of Epithelial cell adhesion molecule (EpCAM) resulting in release of its intracellular domain Ep-ICD into cytoplasm and nucleus triggers oncogenic signaling. We analyzed the expression of Ep-ICD in oral dysplasia and cancer and determined its clinical significance in disease progression and prognosis. In a retrospective study, immunohistochemical analysis of nuclear and cytoplasmic Ep-ICD and EpEx (extracellular domain of EpCAM), was carried out in 115 OSCC, 97 oral dysplasia and 105 normal oral tissues, correlated with clinicopathological parameters and disease outcome over 60 months for oral dysplasia and OSCC patients. Disease-free survival (DFS) was determined by Kaplan-Meier method and multivariate Cox regression analysis. In comparison with normal oral tissues, significant increase in nuclear Ep-ICD and membrane EpEx was observed in dysplasia, and OSCC (p = 0.013 and < 0.001 respectively). Oral dysplasia patients with increased overall Ep-ICD developed cancer in short time period (mean = 47 months; p = 0.044). OSCC patients with increased nuclear Ep-ICD and membrane EpEx had significantly reduced mean DFS of 33.7 months (p = 0.018). Our study provided clinical evidence for Ep-ICD as a predictor of cancer development in patients with oral dysplasia and recurrence in OSCC patients, suggesting its potential utility in enhanced management of those patients detected to have increased risk of progression to cancer and recurrence in OSCC patients

When the science fails and the ethics works: 'Fail-safe' ethics in the FEM-PrEP study.

Kingori, Patricia

2015-12-01

This paper will explore the concept of 'fail safe' ethics in the FEM PrEP trial, and the practice of research and ethics on the ground. FEM-PrEP examined the efficacy of PrEP in African women after promising outcomes in research conducted with MSM. This was a hugely optimistic time and FEM-PrEP was mobilised using rights-based ethical arguments that women should have access to PrEP. This paper will present data collected during an ethnographic study of frontline research workers involved in FEM-PrEP. During our discussions, 'fail-safe' ethics emerged as concept that encapsulated their confidence that their ethics could not fail. However, in 2011, FEM-PrEP was halted and deemed a failure. The women involved in the study were held responsible because contrary to researcher's expectations they were not taking the oral PrEP being researched. This examination of FEM-PrEP will show that ethical arguments are increasingly deployed to mobilise, maintain and in some cases stop trials in ways which, at times, are superseded or co-opted by other interests. While promoting the interests of women, rights-based approaches are argued to indirectly justify the continuation of individualised, biomedical interventions which have been problematic in other women-centred trials. In this examination of FEM-PrEP, the rights-based approach obscured: ethical concerns beyond access to PrEP; the complexities of power relationships between donor and host countries; the operations of the HIV industry in research-saturated areas and the cumulative effect of unfilled expectations in HIV research and how this has shaped ideas of research and ethics.

Brazil's response to the HIV epidemic now includes free access to preexposure prophylaxis (PrEP) to populations at substantial risk for HIV infection including men who have sex with men (MSM). We used nationally representative demographic, epidemiologic, and surveillance data to offer estimates for the number of MSM at substantial risk for HIV infection who might be eligible and willing to use PrEP in Brazil. Starting from the age/sex-stratified population, we calculated the number of men aged 15 to 64 years, in 5-year age groups, and the proportion of those who report sex with other men during their lifetime. We focused on 11 cities (representing all regions) that are responsible for a significant fraction of the HIV burden of the country and used city-specific HIV prevalence estimates to infer the fraction of MSM who are HIV-negative. We then derived the proportion of HIV-negative MSM under substantial risk for HIV infection defined as having unprotected receptive anal intercourse in the 6 months before study participation. Finally, PrEP uptake among the eligible was inferred from the PrEP Brazil study. Our results show that PrEP demand in these 11 cities is of 66,120 men aged 15 to 64 years. When we consider the lower and upper bounds for the available parameters, we find that PrEP demand in these 11 cities might vary from 33,378 to 97,962 men. If PrEP is restricted to those aged 15 to 49 years, demand drops by 20%. PrEP demand varies considerably by city, mostly because of the differences in population size and city-specific HIV prevalence. We have shed light on the probable size of PrEP demand in Brazil certain that the incorporation of PrEP as part of Brazil's combination prevention for populations at substantial risk for HIV infection is a necessary challenge. PrEP will not only prevent HIV infections, it will also expand testing among the most vulnerable with the added benefit of offering combination prevention for the uninfected and immediate treatment for

Despite progress in scaling up antiretroviral treatment, HIV prevention strategies have not been successful in significantly curbing HIV incidence in Latin America. HIV prevention interventions need to be expanded to target the most affected key populations with a combination approach, including new high impact technologies. Oral pre-exposure prophylaxis (PrEP) is recommended as additional prevention choice for individuals at higher risk of infection and could become a cost-effective prevention tool. We discuss the barriers and solutions for a fair consideration of PrEP as part of combination HIV prevention strategies in Latin America. Although demonstration projects are ongoing or being planned in a number of countries, to date no Latin American country has implemented a public PrEP programme. The knowledge of policymakers about PrEP implementation needs to be strengthened, and programmatic guidance and cost estimate tools need to be developed to support adequate planning. Despite high levels of awareness among health providers, especially if engaged in HIV or key population care, willingness to prescribe PrEP is still low due to the lack of national policies and guidelines. Key populations, especially men who have sex with men, transgender women and sex workers, have been engaged in demonstration projects, and qualitative research shows high awareness and willingness to use PrEP, especially if accessible in the public sector for free or at affordable price. Concerns of safety, adherence, effectiveness and risk compensation need to be addressed through targeted social communication strategies to improve PrEP knowledge and stimulate demand. Alliance among policymakers, civil society and representatives from key populations, healthcare providers and researchers will be critical for the design and successful implementation of PrEP demonstration projects of locally adapted delivery models.

The adsorption of Zn onto the humic and illuvial horizons of the podzol soil in the presence of soil bacteria was studied using a batch-reactor technique as a function of the pH (from 2 to 9) and the Zn concentration in solution (from 0.076mM to 0.760mM). Exopolysaccharides-forming aerobic heterotrophs Pseudomonas aureofaciens were added at 0.1 and 1.0gwetL(-1) concentrations to two different soil horizons, and Zn adsorption was monitored as a function of the pH and the dissolved-Zn concentration. The pH-dependent adsorption edge demonstrated more efficient Zn adsorption by the humic horizon than the mineral horizon at otherwise similar soil concentrations. The Zn adsorption onto the EPS-poor strain was on slightly lower than that onto EPS-rich bacteria. Similar differences in the adsorption capacities between the soil and bacteria were also detected by "langmuirian" constant-pH experiments conducted in soil-Zn and bacteria-Zn binary systems. The addition of 0.1gwetL(-1)P. aureofaciens to a soil-bacteria system (4gdryL(-1)soil) resulted in statistically significant decrease in the adsorption yield, which was detectable from both the pH-dependent adsorption edge and the constant-pH isotherm experiments. Increasing the amount of added bacteria to 1gwetL(-1) further decreased the overall adsorption in the full range of the pH. This decrease was maximal for the EPS-rich bacteria and minimal for the EPS-poor bacteria (a factor of 2.8 and 2.2 at pH=6.9, respectively). These observations in binary and ternary systems were further rationalized by linear-programming modeling of surface equilibria that revealed the systematic differences in the number of binding sites and the surface-adsorption constant of zinc onto the two soil horizons with and without bacteria. The main finding of this work is that the adsorption of Zn onto the humic soil-bacteria system is lower than that in pure, bacteria-free soil systems. This difference is statistically significant (psoil particles

Online counseling may be defined as an interaction between users and mental health professionals that takes place through computer mediated communication technology. This study aimed to investigate the attitudes of Italian psychologists towards different aspects of online counseling provided via email, chat, forums, and videoconference. An online questionnaire was administered to a sample of 289 licensed psychologists in the Veneto Region (Italy) in order to collect opinions, preferences, and intentions to use online modalities, along with prior knowledge and practice experiences. Only 18.3% of the respondents had previous experience with online counseling. Overall, the majority of psychologists (62.6%) were favorable towards online counseling, but they also had several reservations about the provision of online diagnosis and therapeutic interventions. Results showed a consistent lack of clarity regarding ethical and penal issues concerning online modalities. More efforts must be directed to deepening the application of new technologies in the field of psychology in order to enable an ethical and professional practice of online counseling in Italy.

Pre-exposure prophylaxis (PrEP) is effective for preventing HIV among HIV-serodiscordant heterosexual couples. Gender roles may influence perceived personal and social risks related to HIV-prevention behaviors and may affect use of PrEP. In this study, interviews and focus groups were conducted with 68 individuals from 34 mutually disclosed serodiscordant heterosexual partnerships in Thika, Kenya. Sociocultural factors that affect adherence to PrEP were explored using grounded analysis. Three factors were identified, which shape perceptions of PrEP: gendered power dynamics and control over decision-making in the household; conflicts between risk-reduction strategies and male sexual desire; culture-bound definitions of women's work. Adherence to PrEP in the Partners PrEP Study was high; however, participants articulated conflicting interests related to PrEP in connection with traditional gender roles. The successful delivery of PrEP will require understanding of key social factors, particularly related to gender and dyadic dynamics around HIV serostatus.

Full Text Available Abstract Background To evaluate the expression and test the clinical significance of the epithelial cellular adhesion molecule (Ep-CAM in esophageal squamous cell carcinoma (SCC to check the suitability of esophageal SCC patients for Ep-CAM directed targeted therapies. Methods The Ep-CAM expression was immunohistochemically investigated in 70 primary esophageal SCCs using the monoclonal antibody Ber-EP4. For the interpretation of the staining results, we used a standardized scoring system ranging from 0 to 3+. The survival analysis was calculated from 53 patients without distant metastasis, with R0 resection and at least 2 months of clinical follow-up. Results Ep-CAM neo-expression was observed in 79% of the tumors with three expression levels, 1+ (26%, 2+ (11% and 3+ (41%. Heterogeneous expression was observed at all expression levels. Interestingly, tumors with 3+ Ep-CAM expression conferred a significantly decreased median relapse-free survival period (log rank, p = 0.0001 and median overall survival (log rank, p = 0.0003. Multivariate survival analysis disclosed Ep-CAM 3+ expression as independent prognostic factor. Conclusion Our results suggest Ep-CAM as an attractive molecule for targeted therapy in esophageal SCC. Considering the discontenting results of the current adjuvant concepts for esophageal SCC patients, Ep-CAM might provide a promising target for an adjuvant immunotherapeutic intervention.

Equilibrium adsorption experiments, isothermal titration calorimetry and potentiometric titration techniques were employed to investigate the adsorption of Cu(II) by extracellular polymeric substances (EPS) extracted from Pseudomonas putida X4, minerals (montmorillonite and goethite) and their composites. Compared with predicted values of Cu(II) adsorption on composites, the measured values of Cu(II) on EPS-montmorillonite composite increased, however, those on EPS-goethite composite decreased. Potentiometric titration results also showed that more surface sites were observed on EPS-montmorillonite composite and less reactive sites were found on EPS-goethite composite. The adsorption of Cu(II) on EPS molecules and their composites with minerals was an endothermic reaction, while that on minerals was exothermic. The positive values of enthalpy change (Delta H) and entropy change (DeltaS) for Cu(II) adsorption on EPS and mineral-EPS composites indicated that Cu(II) mainly interacts with carboxyl and phosphoryl groups as inner-sphere complexes on EPS molecules and their composites with minerals.

Fever in influenza results from the release of endogenous pyrogen (EP) following virus-phagocyte interaction and its level correlates with the differing virulence of virus strains. However, the different levels of fever produced in ferrets by intracardial inoculation of EP obtained from the interaction of different virus strains with ferret of human phagocytes did not correlate with the levels of interleukin 1 (IL-1), IL-6 or tumour necrosis factor in the same samples as assayed by conventional in vitro methods. Hence, the EP produced by influenza virus appears to be different to these cytokines.

The stability and morphology of bedforms have traditionally been treated as a function of mean flow velocity/non-dimensional bed shear stress and sediment particle size, despite the known influence of key biological components such as extracellular polymeric substances (EPS). EPS is produced by microbial communities and can increase erosion thresholds by more than 300%. However, the mechanisms behind the influence of EPS on sediment transport and bedform dynamics is poorly understood, as is the fate of EPS and exchange of EPS between the sediment bed and water column during ripple formation. The exchange of EPS between the sediment bed and water column is dynamic, with important implications for a range of physical and geochemical processes, with the spatio-temporal variation in EPS content, from source to eventual fate, being extremely important for determining the behaviour and natural variability of sedimentary systems. This paper reports on a series of flume experiments where a tripartite mixture of sand, clay and model EPS (xanthan gum) was used to create a sediment substrate, which was subject to a unidirectional current (0.8 ms-1 for 10.5 hrs, n=6). For each run the spatio-temporal changes in concentration, distribution, and effect of EPS, on the evolving bed of mixed sediment was monitored throughout, with complete 3D bed morphology scans also acquired at ~360 s intervals. The various substrate mixtures produced bedforms varying from ripples to dunes and biochemical analysis of EPS concentration across the formed bedforms, suggest EPS is winnowed from the sediment - water interface, particularly at the bedform crests. The depth of winnowing in each run was found to be related to the bedform size, with variation in the stoss, crest and trough of the bedforms identified. The loss of EPS was also significantly correlated with the depth to which clay was winnowed, presumably due to a close association between the clay mineral and EPS fractions. The paper will

A search for the lepton flavour violating processes ep->mu X and ep -> tau X is performed with the H1 experiment at HERA. Final states with a muon or tau and a hadronic jet are searched for in a data sample corresponding to an integrated luminosity of 66.5 pb-1 for e^+ p collisions and 13.7 pb^-1 for e^- p collisions at a centre-of-mass energy of 319 GeV. No evidence for lepton flavour violation is found. Limits are derived on the mass and the couplings of leptoquarks inducing lepton flavour violation in an extension of the Buchm"uller-R"uckl-Wyler effective model.

A search for the lepton flavour violating processes ep{yields}{mu}X and ep{yields}{tau}X is performed with the H1 experiment at HERA. Final states with a muon or tau and a hadronic jet are searched for in a data sample corresponding to an integrated luminosity of 66.5 pb{sup -1} for e{sup +}p collisions and 13.7 pb{sup -1} for e{sup -}p collisions at a centre-of-mass energy of 319 GeV. No evidence for lepton flavour violation is found. Limits are derived on the mass and the couplings of leptoquarks inducing lepton flavour violation in an extension of the Buchmueller-Rueckl-Wyler effective model. Leptoquarks produced in ep collisions with a coupling strength of {lambda}=0.3 and decaying with the same coupling strength to a muon-quark pair or a tau-quark pair are excluded at 95% confidence level up to masses of 459 GeV and 379 GeV, respectively.

QCD studies in ep collisions

International Nuclear Information System (INIS)

Smith, W.H.

1997-01-01

These lectures describe QCD physics studies over the period 1992--1996 from data taken with collisions of 27 GeV electrons and positrons with 820 GeV protons at the HERA collider at DESY by the two general-purpose detectors H1 and ZEUS. The focus of these lectures is on structure functions and jet production in deep inelastic scattering, photoproduction, and diffraction. The topics covered start with a general introduction to HERA and ep scattering. Structure functions are discussed. This includes the parton model, scaling violation, and the extraction of F 2 , which is used to determine the gluon momentum distribution. Both low and high Q 2 regimes are discussed. The low Q 2 transition from perturbative QCD to soft hadronic physics is examined. Jet production in deep inelastic scattering to measure α s , and in photoproduction to study resolved and direct photoproduction, is also presented. This is followed by a discussion of diffraction that begins with a general introduction to diffraction in hadronic collisions and its relation to ep collisions, and moves on to deep inelastic scattering, where the structure of diffractive exchange is studied, and in photoproduction, where dijet production provides insights into the structure of the Pomeron. 95 refs., 39 figs

Wright, Daniel B

2009-11-01

Although psychologists frequently use statistical procedures, they are often unaware of the statisticians most associated with these procedures. Learning more about the people will aid understanding of the techniques. In this article, I present a list of 10 prominent statisticians: David Cox, Bradley Efron, Ronald Fisher, Leo Goodman, John Nelder, Jerzy Neyman, Karl Pearson, Donald Rubin, Robert Tibshirani, and John Tukey. I then discuss their key contributions and impact for psychology, as well as some aspects of their nonacademic lives. © 2009 Association for Psychological Science.

Heavy Quark Production in ep Collisions at HERA

Bloch, I.

2006-01-01

Collisions of electrons with protons at a centre-of-mass energy of 318 GeV are being recorded by the two experiments H1 and ZEUS at the ep accelerator HERA at DESY, Hamburg (Germany). Measurements involving beauty and charm quarks, performed by these experiments, provide a good environment to test perturbative QCD predictions as the large quark mass supplies a hard scale. Recent measurements of beauty and charm production in ep collisions are presented here. QCD predictions at next-to-leading order are found to generally agree with the measurements. Beauty measurements however are sometimes slightly higher than the predicted cross sections. Beauty and charm contributions to the proton structure were also measured and are well described by QCD predictions

Production of Z0 bosons in elastic and quasi-elastic ep collisions at HERA

2012-10-01

The production of Z 0 bosons in the reaction ep → eZ 0 p (*) , where p (*) stands for a proton or a low-mass nucleon resonance, has been studied in ep collisions at HERA using the ZEUS detector. The analysis is based on a data sample collected between 1996 and 2007, amounting to 496 pb -1 of integrated luminosity. The Z 0 was measured in the hadronic decay mode. The elasticity of the events was ensured by a cut on η max max is the maximum pseudorapidity of energy deposits in the calorimeter defined with respect to the proton beam direction. A signal was observed at the Z 0 mass. The cross section of the reaction ep → eZ 0 p (*) was measured to be σ (ep → eZ 0 p (*) ) = 0.13 ± 0.06 (stat.) ± 0.01 (syst.) pb, in agreement with the Standard Model prediction of 0.16 pb. This is the first measurement of Z 0 production in ep collisions.

Castor oil induces laxation and uterus contraction via ricinoleic acid activating prostaglandin EP3 receptors.

Science.gov (United States)

Tunaru, Sorin; Althoff, Till F; Nüsing, Rolf M; Diener, Martin; Offermanns, Stefan

Castor oil is one of the oldest drugs. When given orally, it has a laxative effect and induces labor in pregnant females. The effects of castor oil are mediated by ricinoleic acid, a hydroxylated fatty acid released from castor oil by intestinal lipases. Despite the wide-spread use of castor oil in conventional and folk medicine, the molecular mechanism by which ricinoleic acid acts remains unknown. Here we show that the EP(3) prostanoid receptor is specifically activated by ricinoleic acid and that it mediates the pharmacological effects of castor oil. In mice lacking EP(3) receptors, the laxative effect and the uterus contraction induced via ricinoleic acid are absent. Although a conditional deletion of the EP(3) receptor gene in intestinal epithelial cells did not affect castor oil-induced diarrhea, mice lacking EP(3) receptors only in smooth-muscle cells were unresponsive to this drug. Thus, the castor oil metabolite ricinoleic acid activates intestinal and uterine smooth-muscle cells via EP(3) prostanoid receptors. These findings identify the cellular and molecular mechanism underlying the pharmacological effects of castor oil and indicate a role of the EP(3) receptor as a target to induce laxative effects.

Rubinstein-Taybi syndrome (RSTS) is a heterogeneous disorder with approximately 45-55% of patients showing mutations in the CREB binding protein and a further 3% of patients having mutations in EP300. We report a male child with a deletion of exons 3-8 of the EP300 gene who has RSTS. He has a milder skeletal phenotype, a finding that has been described in other cases with EP300 mutations. The mother suffered from pre-eclampsia and HELLP syndrome in the pregnancy. She subsequently developed a mullerian tumor of her cervix 6 years after the birth of her son.

The free volume properties of epoxy/hydroxyl terminated butyl nitrile rubber (EP/HTBN) have been studied by means of positron annihilation technique. The toughness effect is found to be correlated with the content of HTBN and the free volume properties of the EP/HTBN interfaces. When the content of HTBN component is 5%, the free volume size in the interface is close to that of EP, and the toughness effect is strong. But with further addition of HTBN, holes with big size free volume are formed in the interface, and the toughness effect is limited. (authors)

Women, behavior, and evolution: understanding the debate between feminist evolutionists and evolutionary psychologists.

Science.gov (United States)

Liesen, Laurette T

2007-03-01

Often since the early 1990s, feminist evolutionists have criticized evolutionary psychologists, finding fault in their analyses of human male and female reproductive behavior. Feminist evolutionists have criticized various evolutionary psychologists for perpetuating gender stereotypes, using questionable methodology, and exhibiting a chill toward feminism. Though these criticisms have been raised many times, the conflict itself has not been fully analyzed. Therefore, I reconsider this conflict, both in its origins and its implications. I find that the approaches and perspectives of feminist evolutionists and evolutionary psychologists are distinctly different, leading many of the former to work in behavioral ecology, primatology, and evolutionary biology. Invitingly to feminist evolutionists, these three fields emphasize social behavior and the influences of environmental variables; in contrast, evolutionary psychology has come to rely on assumptions deemphasizing the pliability of psychological mechanisms and the flexibility of human behavior. In behavioral ecology, primatology, and evolutionary biology, feminist evolutionists have found old biases easy to correct and new hypotheses practical to test, offering new insights into male and female behavior, explaining the emergence and persistence of patriarchy, and potentially bringing closer a prime feminist goal, sexual equality.

Here, in order to mitigate this intrinsic drawback of DM1, we developed mesoporous silica nanoparticles (MSNs loaded with DM1 and surface-decorated with hydrochloride dopamine (PDA, polyethylene glycol (PEG, and epithelial cell adhesion molecule (EpCAM aptamer (APt for the targeted treatment of colorectal cancer (CRC. In this system, the PDA coating could be used as pH-sensitive gatekeepers to control the release of DM1 from MSNs in response to the pH stimulus and EpCAM APt-guided active targeting enables the increased delivery of DM1 to CRC as well as a reduction in toxicity and side effects by minimizing the exposure of normal tissues to DM1. Results demonstrated that DM1 inhibited the formation of microtubules and induced apoptosis in tumor cells via caspase signaling. In comparison with the control groups, the MSNs-DM1@PDA-PEG-APt bioconjugates exhibited

Clinical psychologists' views of intensive interaction as an intervention in learning disability services.

Science.gov (United States)

Berry, Ruth; Firth, Graham; Leeming, Catherine; Sharma, Vishal

2014-01-01

Intensive Interaction was initially developed in the 1980s as an educational approach for developing social communication and engagement with people with severe or profound intellectual disabilities and/or autism. Intensive Interaction has subsequently been adopted by a range of practitioners and professionals working in learning disability services and has a broad multi-disciplinary acceptance, being recommended in a number of UK governmental guidance documents. Despite this, there has been limited work on developing a deeper psychological understanding of the approach. This study utilises a qualitative description/thematic analysis approach to explore how clinical psychologists conceptualise the approach with regard to currently accepted psychological theories, as well as looking at other factors that influence their adoption and advocacy. The sample deliberately consisted of eight NHS (National Health Service) clinical psychologists known to be using or advocating the use of Intensive Interaction with people with a learning disability. The results of this study indicate that although the participants referred to some theories that might explain the beneficial outcomes of Intensive Interaction, these theories were rarely explicitly or clearly referenced, resulting in the authors having to attribute specific theoretical positions on the basis of inductive analysis of the participants' responses. Moreover, the participants provided varying views on how Intensive Interaction might be conceptualised, highlighting the lack of a generally accepted, psychologically framed definition of the approach. In conclusion, it was felt that further research is required to develop a specifically psychological understanding of Intensive Interaction alongside the formation of a Special Interest Group, which might have this task as one of its aims. There appeared to be a limited recognition amongst the participants of the specific psychological theories that can be seen to explain

'PrEP is not ready for our community, and our community is not ready for PrEP': pre-exposure prophylaxis for HIV for people who inject drugs and limits to the HIV prevention response.

Science.gov (United States)

Guise, Andy; Albers, Eliot Ross; Strathdee, Steffanie A

2017-04-01

Pre-exposure prophylaxis for HIV, or 'PrEP', is the use of antiretroviral medicines by people who are HIV-negative to protect themselves against acquiring HIV. PrEP has shown efficacy for preventing HIV acquisition. Despite the potential, many concerns have been voiced by people who inject drugs (PWID) and their organizations. There is a need to engage with these views and ensure their integration in to policy and strategy. This paper presents PWID views on PrEP to foster the uptake of these opinions into scientific and policy debate around PrEP METHODS: Critical analysis of a report of a community consultation led by the International Network of People who Use Drugs (INPUD). The INPUD report highlights enthusiasm from PWID for PrEP, but also three main concerns: the feasibility and ethics of PrEP, its potential use as a substitute for other harm reduction strategies and how a focus on PrEP heralds a re-medicalization of HIV. Each concern relates to evidenced gaps in essential services or opposition to harm reduction and PWID human rights. People who use drugs have fundamental concerns about the potential impacts of pre-exposure prophylaxis for HIV which reflect a 'fault line' in HIV prevention: a predominance of biomedical approaches over community perspectives. Greater community engagement in HIV prevention strategy is needed, or we risk continuing to ignore the need for action on the underlying structural drivers and social context of the HIV epidemic. © 2016 Society for the Study of Addiction.

Though recommended, participation of patients with specific expertise in therapeutic education programs (TEP) is rare. This work reports the experience of a national reference centre for rare systemic diseases. Involvement of "expert patients" (EP) has been planned from the development of a TEP dedicated to systemic lupus: patients' roles and required expertise have been defined and linked to the pedagogical tools. Such patients have been recruited during individual interviews and called to participate to specific pedagogical training. EP intervention have been evaluated by questionnaire to EP and health care providers. Three EP's functions have been identified: sharing experiences, giving "tips and tricks" and promoting dialogue. EP's interventions has been organised into a hierarchy (from sharing to co-animation). Among 298 patients enrolled in the TEP, 25 (8.4%) have been identified as possible EP. Eight of them (32%) benefited from a specific training of 12 hours. Among these patients, two (25%) regularly participate to the education sessions. For EP as well as for health care providers, EP's intervention seems beneficial (visual scale scores of 7.5 and 9.5, respectively). Though difficult to organise, EP's intervention in TEP dedicated to rare systemic diseases seems useful and would earn to be increase.

2015-10-01

Extracellular polymeric substances (EPS) play an important role in the treatment of acid mine drainage (AMD) by sulfate-reducing bacteria (SRB). In this paper, Desulfovibrio desulfuricans was used as the test strain to explore the effect of heavy metals on the components and adsorption ability of EPS. Fourier-transform infrared (FTIR) spectroscopy analysis results showed that heavy metals did not influence the type of functional groups of EPS. Potentiometric titration results indicated that the acidic constants (pKa) of the EPS fell into three ranges of 3.5-4.0, 5.9-6.7, and 8.9-9.8. The adsorption site concentrations of the surface functional groups also increased. Adsorption results suggested that EPS had a specific binding affinity for the dosed heavy metal, and that EPS extracted from the Zn(2+)-dosed system had a higher binding affinity for all heavy metals. Additionally, Zn(2+) decreased the inhibitory effects of Cd(2+) and Cu(2+) on the SRB. Copyright © 2015 Elsevier Ltd. All rights reserved.

Unplanned dialysis start (UPS) leads to worse clinical outcomes than planned start, and only a minority of patients ever receive education on this topic and are able to make a modality choice, particularly for home dialysis. This study aimed to determine the predictive factors for patients receiving education, making a decision, and receiving their preferred modality choice in UPS patients following a UPS educational program (UPS-EP). The Offering Patients Therapy Options in Unplanned Start (OPTiONS) study examined the impact of the implementation of a specific UPS-EP, including decision support tools and pathway improvement on dialysis modality choice. Linear regression models were used to examine the factors predicting three key steps: referral and receipt of UPS-EP, modality decision making, and actual delivery of preferred modality choice. A simple economic assessment was performed to examine the potential benefit of implementing UPS-EP in terms of dialysis costs. The majority of UPS patients could receive UPS-EP (214/270 patients) and were able to make a decision (177/214), although not all patients received their preferred choice (159/177). Regression analysis demonstrated that the initial dialysis modality was a predictive factor for referral and receipt of UPS-EP and modality decision making. In contrast, age was a predictor for referral and receipt of UPS-EP only, and comorbidity was not a predictor for any step, except for myocardial infarction, which was a weak predictor for lower likelihood of receiving preferred modality. Country practices predicted UPS-EP receipt and decision making. Economic analysis demonstrated the potential benefit of UPS-EP implementation because dialysis modality costs were associated with modality distribution driven by patient preference. Education and decision support can allow UPS patients to understand their options and choose dialysis modality, and attention needs to be focused on ensuring equity of access to educational

Prostaglandin E2 EP2 Receptor Deletion Attenuates Intracerebral Hemorrhage-Induced Brain Injury and Improves Functional Recovery

Full Text Available Intracerebral hemorrhage (ICH is a devastating type of stroke characterized by bleeding into the brain parenchyma and secondary brain injury resulting from strong neuroinflammatory responses to blood components. Production of prostaglandin E2 (PGE2 is significantly upregulated following ICH and contributes to this inflammatory response in part through its E prostanoid receptor subtype 2 (EP2. Signaling through the EP2 receptor has been shown to affect outcomes of many acute and chronic neurological disorders; although, not yet explored in the context of ICH. Wildtype (WT and EP2 receptor knockout (EP2−/− mice were subjected to ICH, and various anatomical and functional outcomes were assessed by histology and neurobehavioral testing, respectively. When compared with age-matched WT controls, EP2−/− mice had 41.9 ± 4.7% smaller ICH-induced brain lesions and displayed significantly less ipsilateral hemispheric enlargement and incidence of intraventricular hemorrhage. Anatomical outcomes correlated with improved functional recovery as identified by neurological deficit scoring. Histological staining was performed to begin investigating the mechanisms involved in EP2-mediated neurotoxicity after ICH. EP2−/− mice exhibited 45.5 ± 5.8% and 41.4 ± 8.1% less blood and ferric iron accumulation, respectively. Furthermore, significantly less striatal and cortical microgliosis, striatal and cortical astrogliosis, blood–brain barrier breakdown, and peripheral neutrophil infiltration were seen in EP2−/− mice. This study is the first to suggest a deleterious role for the PGE2-EP2 signaling axis in modulating brain injury, inflammation, and functional recovery following ICH. Targeting the EP2 G protein-coupled receptor may represent a new therapeutic avenue for the treatment of hemorrhagic stroke.

Tay, Stacie; Alcock, Kat; Scior, Katrina

2018-03-24

To assess the prevalence of personal experiences of mental health problems among clinical psychologists, external, perceived, and self-stigma among them, and stigma-related concerns relating to disclosure and help-seeking. Responses were collected from 678 UK-based clinical psychologists through an anonymous web survey consisting of the Social Distance Scale, Stig-9, Military Stigma Scale, Secrecy Scale, Attitudes towards Seeking Professional Psychological Help Scale-Short Form, alongside personal experience and socio-demographic questions. Two-thirds of participants had experienced mental health problems themselves. Perceived mental health stigma was higher than external and self-stigma. Participants were more likely to have disclosed in their social than work circles. Concerns about negative consequences for self and career, and shame prevented some from disclosing and help-seeking. Personal experiences of mental health problems among clinical psychologists may be fairly common. Stigma, concerns about negative consequences of disclosure and shame as barriers to disclosure and help-seeking merit further consideration. © 2018 Wiley Periodicals, Inc.

Full Text Available As with other areas, the growth of occupational and organizational psychology is based on scientific research, variety of situational factors and trends, and needs that arise in the organizational environment. The aim of the study was to describe the tasks carried out by psychologists in organizations in the past (55 years long history of the field in Slovenia, and to compare these with the tasks that are currently performed. The results were compared with similar studies that had been conducted in Slovenia. The results reveal that the work carried out by psychologists in organizations is currently more diverse, but also more focused on specific forms of work, particularly those related to psychological assessment, counseling, and motivation. Their duties are now more likely to be conducted in an international environment and involve working directly with employees and leaders. Participants also gave recommendations to psychologists who work or want to work in the field of organizational psychology.

References to Human Rights in Codes of Ethics for Psychologists: Critical Issues and Recommendations. Part 1

Directory of Open Access Journals (Sweden)

Жанель Готье

2018-12-01

Full Text Available There are codes of ethics in psychology that explicitly refer to human rights. There are also psychologists interested in the protection and promotion of human rights who are calling for the explicit inclusion of references to human rights in all psychology ethics codes. Yet, references to human rights in ethics documents have rarely been the focus of attention in psychological ethics. This article represents the first part of a two-part article series focusing on critical issues associated with the inclusion of references to human rights in the ethical codes of psychologists, and recommendations about how psychological ethics and the human rights movement can work together in serving humanity. The first part of the article series examines issues pertaining to the interpretation of references to human rights in codes of ethics for psychologists, and the justifications for including these references in psychological ethics codes. The second part of the article series examines how the Universal Declaration of Ethical Principles for Psychologists can be used to extend or supplement codes of ethics in psychology, how ethical principles and human rights differ and complement each other, and how psychological ethics and the human rights movement can work together in serving humanity and improving the welfare of both persons and peoples.

Primary care psychology services (PCPS) represent an important resource in meeting the various health needs of our communities. This study evaluated the PCPS in a two-county area within the Republic of Ireland. The objectives were to (i) examine the viewpoints of the service for both psychologists and stakeholders (healthcare professionals only) and (ii) examine the enactment of the stepped care model of service provision. Separate surveys were sent to primary care psychologists (n = 8), general practitioners (GPs; n = 69) and other stakeholders in the two counties. GPs and stakeholders were required to rate the current PCPS. The GP survey specifically examined referrals to the PCPS and service configuration, while the stakeholder survey also requested suggestions for future service provision. Psychologists were required to provide information regarding their workload, time spent on certain tasks and productivity ideas. Referral numbers, waiting lists and waiting times were also obtained. All 8 psychologists, 23 GPs (33% response rate) and 37 stakeholders (unknown response rate) responded. GPs and stakeholders reported access to the PCPS as a primary concern, with waiting times of up to 80 weeks in some areas. Service provision to children and adults was uneven between counties. A stepped care model of service provision was not observed. Access can be improved by further implementation of a stepped care service, developing a high-throughput service for adults (based on a stepped care model), and employing a single waiting list for each county to ensure equal access. © 2016 John Wiley & Sons Ltd.

Corporate actions for the climate - Greenhouse gas reduction practices at EpE member companies

International Nuclear Information System (INIS)

Chalendar, Pierre-Andre de

2012-11-01

Corporate awareness of the reality of climate change and the impact of human activity on global warming goes back some twenty years. It was at this time that EpE members decided to take voluntary action towards lowering greenhouse gas emissions. EpE member companies started out by measuring their emissions (see EpE publication entitled 'Measuring and Controlling Greenhouse Gas Emissions'), then worked to identify initiatives easiest to implement and those that would have the best reduction potential. This booklet is prepared to contribute to other businesses improving their knowledge and understanding of the best practices identified and implemented by EpE members, in order to speed up the reduction of global emissions, without hampering their competitiveness. The practices showcased here have intentionally been detailed so that they can be easier to adopt. (authors)

E&P data lifecycle: a case study in Petrobras Company

Science.gov (United States)

Mastella, Laura; Campinho, Vania; Alonso, João

2013-04-01

Petrobras, the biggest Brazilian Petroleum Company, has been studying and working on Brazilian sedimentary basins for nearly 60 years. The corporate database currently registers over 25000 wells and all their associated products (geophysical logs, cores, sidewall samples) and analyses. There are thousands of samples, descriptions, pictures, measures, and other scientific data resulted from petroleum exploration and production. This data constitutes a huge scientific database which is applied to support Petrobras economic strategy. Geological models built during the exploration phase continue to be refined during both the development and production phases: data should be continually manipulated, correlated and integrated. As E&P assets reach maturity, a new cycle starts: data is re-analyzed and new hypotheses are made in order to increase hydrocarbon productivity. Initial geological models then evolve from accumulated knowledge throughout all the E&P phases. Therefore the quality control must be performed in the first phases of data acquisition, i.e., during the exploration phase, to avoid reworking and loss of information. The last decade witnessed a great evolution in petroleum industry technology. As a consequence, the complexity and particulars of the information generated have increased accordingly. Current technology has also facilitated access to networks and databases, making it possible to store large amounts of information. This scenario makes available a large mass of information from difference sources, which uses heterogeneous vocabulary as well as different scales and measurement units. In this context, knowledge might be diluted and the total amount of information cannot be applied in E&P process. In order to provide adequate data governance, data input is controlled by rules, standards and policies, implemented by corporate software systems. Petrobras' integrated E&P database is a centralized repository to which all E&P systems can have access. The

To investigate the effects of lead(II) on the production of extracellular polysaccharides (EPS), including bound extracellular polysaccharides (bEPS) and soluble extracellular polysaccharides (sEPS), and the colony formation of Microcystis aeruginosa, cultures of M. aeruginosa were exposed to four concentrations (5.0, 10.0, 20.0 and 40.0 mg/L) of lead(II) for 10 d under controlled laboratory conditions. The results showed that 5.0 and 10.0 mg/L lead(II) stimulated M. aeruginosa growth throughout the experiment while 20.0 and 40.0 mg/L lead(II) inhibited M. aeruginosa growth in the first 2 d exposure and then stimulated it. As compared to the control group, significant increases in the bEPS and sEPS production were observed in 20.0 and 40.0 mg/L lead(II) treatments (P bEPS production, which conversely promoted colony formation, suggesting that heavy metals might be contributing to the bloom-forming of M. aeruginosa in natural conditions.

Rated casemix of general practitioner referrals to practice counsellors and clinical psychologists: a retrospective survey of a year's caseload.

Cape, J; Parham, A

2001-06-01

Although evidence-based guidelines are beginning to be produced as to which psychological therapies might be appropriate for which patients, little is known about how general medical practitioners (GPs) in practice distribute referrals between different psychological therapy services. In a retrospective survey, 19 practice counsellors and 10 clinical psychologists from the same geographical area rated a year's caseload of GP referrals using identical data collection methods. Rated casemix was found to be broadly similar, although practice counsellors rated relationship and bereavement problems as more common in their caseloads (totalling 986 patients), and clinical psychologists rated panic disorder, phobias, and obsessive-compulsive problems as more common in their caseloads (totalling 320 patients). Depression and anxiety reactions were the most common problems rated in both groups, but the clinical psychologist cases of depression were rated as more severe and complex. Where differences were found, they may have reflected the different ways that counsellors and clinical psychologists conceptualize cases rather than actual differences in casemix. The results are discussed in relation to evidence-based guideline recommendations about cases appropriate to be seen by practice counsellors and by clinical psychologists in primary and secondary care, and the need to adapt such guidance to local services and skills of practitioners.

Rooting gene trees without outgroups: EP rooting.

Sinsheimer, Janet S; Little, Roderick J A; Lake, James A

2012-01-01

Gene sequences are routinely used to determine the topologies of unrooted phylogenetic trees, but many of the most important questions in evolution require knowing both the topologies and the roots of trees. However, general algorithms for calculating rooted trees from gene and genomic sequences in the absence of gene paralogs are few. Using the principles of evolutionary parsimony (EP) (Lake JA. 1987a. A rate-independent technique for analysis of nucleic acid sequences: evolutionary parsimony. Mol Biol Evol. 4:167-181) and its extensions (Cavender, J. 1989. Mechanized derivation of linear invariants. Mol Biol Evol. 6:301-316; Nguyen T, Speed TP. 1992. A derivation of all linear invariants for a nonbalanced transversion model. J Mol Evol. 35:60-76), we explicitly enumerate all linear invariants that solely contain rooting information and derive algorithms for rooting gene trees directly from gene and genomic sequences. These new EP linear rooting invariants allow one to determine rooted trees, even in the complete absence of outgroups and gene paralogs. EP rooting invariants are explicitly derived for three taxon trees, and rules for their extension to four or more taxa are provided. The method is demonstrated using 18S ribosomal DNA to illustrate how the new animal phylogeny (Aguinaldo AMA et al. 1997. Evidence for a clade of nematodes, arthropods, and other moulting animals. Nature 387:489-493; Lake JA. 1990. Origin of the metazoa. Proc Natl Acad Sci USA 87:763-766) may be rooted directly from sequences, even when they are short and paralogs are unavailable. These results are consistent with the current root (Philippe H et al. 2011. Acoelomorph flatworms are deuterostomes related to Xenoturbella. Nature 470:255-260).

A search for scalar and vector leptoquarks coupling to first generation fermions is performed using the e^+p and e^-p scattering data collected by the H1 experiment between 1994 and 2000. The data correspond to a total integrated luminosity of 117 pb^{-1}. No evidence for the direct or indirect production of such particles is found in data samples with a large transverse momentum final state electron or with large missing transverse momentum. Constraints on leptoquark models are established. For leptoquark couplings of electromagnetic strength, leptoquarks with masses up to 275-325 GeV are ruled out. These limits improve and supercede earlier H1 limits based on subsamples of the data used here.

We present EP-DNN, a protocol for predicting enhancers based on chromatin features, in different cell types. Specifically, we use a deep neural network (DNN)-based architecture to extract enhancer signatures in a representative human embryonic stem cell type (H1) and a differentiated lung cell type (IMR90). We train EP-DNN using p300 binding sites, as enhancers, and TSS and random non-DHS sites, as non-enhancers. We perform same-cell and cross-cell predictions to quantify the validation rate and compare against two state-of-the-art methods, DEEP-ENCODE and RFECS. We find that EP-DNN has superior accuracy with a validation rate of 91.6%, relative to 85.3% for DEEP-ENCODE and 85.5% for RFECS, for a given number of enhancer predictions and also scales better for a larger number of enhancer predictions. Moreover, our H1 → IMR90 predictions turn out to be more accurate than IMR90 → IMR90, potentially because H1 exhibits a richer signature set and our EP-DNN model is expressive enough to extract these subtleties. Our work shows how to leverage the full expressivity of deep learning models, using multiple hidden layers, while avoiding overfitting on the training data. We also lay the foundation for exploration of cross-cell enhancer predictions, potentially reducing the need for expensive experimentation.

In this paper, we introduced expanded perlite (EP) into the system of ferrite composites for the first time. By sol-gel self-propagating combustion method, expanded perlite/barium ferrite (EP/BaFe{sub 12}O{sub 19}) was prepared, and then ternary composites of expanded perlite/barium ferrite/polyaniline (EP/BaFe{sub 12}O{sub 19}/PANI) were obtained by in-situ oxidative polymerization of aniline on EP/BaFe{sub 12}O{sub 19} mixture. Although, as is well known, the values of saturation magnetization (Ms), remnant magnetization (Mr) and coercivity (Hc) of composites are all lower than the pure BaFe{sub 12}O{sub 19} particles owing to the existence of the nonmagnetic EP and PANI, the EP/BaFe{sub 12}O{sub 19}/PANI composites exhibit absorption characteristics at the range of 2–18 GHz, the effective absorption bandwidth (less than −4 dB) reached 12.12 GHz and the minimum reflection loss of −5.66 dB at 8.48 GHz with only 2 mm thickness of absorbing layer. So the composites could resist urban electromagnetic pollution, such as wireless network, communication and so on, effectively. - Highlights: • The expanded perlite (EP) was introduced into the system of ferrite composites at the first time. • Novel ternary nanocomposite of EP/BaFe{sub 12}O{sub 19}/PANI is prepared by in-situ oxidative polymerization. • Composite absorber exhibit a minimum reflection loss of -5.66 dB at 8.48 GHz with a matching thickness of 2 mm. • Composite absorber possess the features like low-cost, lightweight and wide bandwidth absorption of civil EM radiation.

Biofilms, consisting of microorganisms and their secreted extracellular polymeric substances (EPSs), serve as "ecosystem engineers" stabilizing sedimentary environments. Natural sediment bed provides an excellent substratum for biofilm growth. The porous structure and rich nutrients allow the EPS matrix to spread deeper into the bed. A series of laboratory-controlled experiments were conducted to investigate sediment colonization of Bacillus subtilis and the penetration of EPS into the sediment bed with incubation time. In addition to EPS accumulation on the bed surface, EPS also penetrated downward. However, EPS distribution developed strong vertical heterogeneity with a much higher content in the surface layer than in the bottom layer. Scanning electron microscope images of vertical layers also displayed different micromorphological properties of sediment-EPS matrix. In addition, colloidal and bound EPSs exhibited distinctive distribution patterns. After the full incubation, the biosedimentary beds were eroded to test the variation of bed stability induced by biological effects. This research provides an important reference for the prediction of sediment transport and hence deepens the understanding of the biologically mediated sediment system and broadens the scope of the burgeoning research field of "biomorphodynamics."

The aim of this work was to assess the uptake of Fe(II) by extracellular polymeric substances (EPS) from the acidophilic bacterium Acidiphillium 3.2Sup(5). These EPS were extracted using EDTA. EPS of A. 3.2Sup(5) loaded in sorption tests with Fe(II), were characterized using the following experimental techniques: scanning electron microscopy (SEM) with energy dispersive X-ray microanalysis (EDX), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The experimental results indicate that EPS adsorb ferrous iron according to Freundlich model with a metal sorption uptake of K = 1.14 mg1−1/n L1/n g−1 and a sorption intensity of 1/n = 1.26. In addition, ferrous iron sorption by EPS took place by preferential interaction with the carboxyl group which promotes the formation of ferrous iron oxalates (FeC2O4). Since the interaction reaction was reversible (Log K = 0.77 ± 0.33), that means that the cation sorption can be reversed at convenience. (Author)

Full Text Available This study used steel fibre as reinforcement while enhancing the EPS-LWC strength. In line with architectural demand and ventilation requirement, opening within wall panel was also taken into account. Experimental tests were conducted for reinforced and unreinforced EPS-LWC wall panel. Two samples with size of 1500 mm (height x 1000 mm (length x 75 mm (thickness for each group of wall panel were prepared. Samples in each group had opening size of 600 mm (height x 400 mm (length located at 350 mm and 550 mm from upper end respectively. EPS-LWC wall panel had fcu of 20.87 N/mm2 and a density of 1900 kg/m3. The loading capacity, displacement profiles and crack pattern of each sample was analyzed and discussed. Unreinforced EPS-LWC enhanced with steel fibre resist almost similar loading as reinforced EPS-LWC wall panel. The presence of steel fibre as the only reinforcement creates higher lateral displacement. Wall panel experience shear failure at the side of opening. The number of micro cracks reduces significantly due to presence of steel fibre.

Person-first and identity-first language: Developing psychologists' cultural competence using disability language.

Science.gov (United States)

Dunn, Dana S; Andrews, Erin E

2015-04-01

The American Psychological Association (APA) advocates the use of person-first language (e.g., people with disabilities) to refer to individuals with disabilities in daily discourse and to reduce bias in psychological writing. Disability culture advocates and disability studies scholars have challenged the rationale for and implications of exclusive person-first language use, promoting use of identity-first language (e.g., disabled people). We argue that psychologists should adopt identity-first language alongside person-first constructions to address the concerns of disability groups while promoting human dignity and maintaining scientific and professional rigor. We review the evolution of disability language and then discuss the major models used to characterize disability and people with disabilities. The rationale for person-first language and the emergence of identity-first language, respectively, are linked to particular models. We then discuss some language challenges posed by identity-first language and the current intent of person-first language, suggesting that psychologists make judicious use of the former when it is possible to do so. We conclude by offering five observations of ways that use of both person-first and identity-first language could enhance psychologists' cultural competence regarding disability issues in personal and scientific communications.

Obesity, a known risk factor for pancreatic cancer, is associated with inflammation and insulin resistance. Proinflammatory prostaglandin E2 (PGE2) and elevated insulin-like growth factor type 1 (IGF-1), related to insulin resistance, are shown to play critical roles in pancreatic cancer progression. We aimed to explore a potential cross talk between PGE2 signaling and the IGF-1/Akt/mammalian target of rapamycin complex 1 (mTORC1) pathway in pancreatic cancer, which may be a key to unraveling the obesity-cancer link. In PANC-1 human pancreatic cancer cells, we showed that PGE2 stimulated mTORC1 activity independently of Akt, as evaluated by downstream signaling events. Subsequently, using pharmacological and genetic approaches, we demonstrated that PGE2-induced mTORC1 activation is mediated by the EP4/cAMP/PKA pathway, as well as an EP1/Ca(2+)-dependent pathway. The cooperative roles of the two pathways were supported by the maximal inhibition achieved with the combined pharmacological blockade, and the coexistence of highly expressed EP1 (mediating the Ca(2+) response) and EP2 or EP4 (mediating the cAMP/PKA pathway) in PANC-1 cells and in the prostate cancer line PC-3, which also robustly exhibited PGE2-induced mTORC1 activation, as identified from a screen in various cancer cell lines. Importantly, we showed a reinforcing interaction between PGE2 and IGF-1 on mTORC1 signaling, with an increase in IL-23 production as a cellular outcome. Our data reveal a previously unrecognized mechanism of PGE2-stimulated mTORC1 activation mediated by EP4/cAMP/PKA and EP1/Ca(2+) signaling, which may be of great importance in elucidating the promoting effects of obesity in pancreatic cancer. Ultimately, a precise understanding of these molecular links may provide novel targets for efficacious interventions devoid of adverse effects. Copyright © 2015 the American Physiological Society.

Deposition of extracellular polymeric substances (EPS) on membrane surfaces is a precursor step for bacterial attachment. The purpose of this study was to analyze the morphological changes on a clean polysulfone ultrafilration membrane after exposure to effluent from a membrane bioreactor. The effluent was filtered to remove bacteria before exposing the membrane. The morphological characterization was performed by atomic force microscopy (AFM). The lateral (2D) and central growth characteristics (3D) of the EPS deposits were evaluated by section and topographical analyses of the height images. The contact angle of single EPS units was 9.07 ± 0.50° which increased to 24.41 ± 1.00° for large clusters (over 10 units) and decreased to 18.68 ± 1.00° for the multilayered clusters. The surface tension of the single EPS units was 49.34 ± 1.70 mNm(-1). The surface tension of single layered small and large EPS clusters were 51.26 ± 2.05 and 53.48 ± 2.01 mNm(-1), respectively. For the multilayered clusters, the surface tension was 51.43 ± 2.05 mNm(-1). The spreading values were negative for all deposits on the polysulfone membrane indicating that the EPS clusters did not have tendency to spread but preferred to retain their shapes.

Recent experiments have confirmed the importance of strange quarks in the description of the spin structure of the proton. This unexpected fact has spurred an intense experimental activity to study the contribution of strange quarks to other aspects of the nucleon. In this framework experiments have been designed to weigh up this contribution to the charge distribution and the magnetization of the nucleon. The experimental way that leads to the measuring of the s-quark contribution is presented. The strange form factor can be deduced from the weak form factor of the proton combined with its electromagnetic form factors. The weak form factor can be measured by studying parity violation in ep elastic scattering. One of the chapters reviews the experimental equipment required to perform parity breaking measurements.The preliminary results of 2 experiments: SAMPLE and HAPPEX are given. (A.C.)

Rubinstein-Taybi syndrome (RSTS) is a developmental disorder characterized by a typical face and distal limbs abnormalities, intellectual disability, and a vast number of other features. Two genes are known to cause RSTS, CREBBP in 60% and EP300 in 8-10% of clinically diagnosed cases. Both paralogs act in chromatin remodeling and encode for transcriptional co-activators interacting with >400 proteins. Up to now 26 individuals with an EP300 mutation have been published. Here, we describe the phenotype and genotype of 42 unpublished RSTS patients carrying EP300 mutations and intragenic deletions and offer an update on another 10 patients. We compare the data to 308 individuals with CREBBP mutations. We demonstrate that EP300 mutations cause a phenotype that typically resembles the classical RSTS phenotype due to CREBBP mutations to a great extent, although most facial signs are less marked with the exception of a low-hanging columella. The limb anomalies are more similar to those in CREBBP mutated individuals except for angulation of thumbs and halluces which is very uncommon in EP300 mutated individuals. The intellectual disability is variable but typically less marked whereas the microcephaly is more common. All types of mutations occur but truncating mutations and small rearrangements are most common (86%). Missense mutations in the HAT domain are associated with a classical RSTS phenotype but otherwise no genotype-phenotype correlation is detected. Pre-eclampsia occurs in 12/52 mothers of EP300 mutated individuals versus in 2/59 mothers of CREBBP mutated individuals, making pregnancy with an EP300 mutated fetus the strongest known predictor for pre-eclampsia. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Up the years with the Bettersons: Gender and parent education in interwar America.

Science.gov (United States)

Johnson, Ann; Johnston, Elizabeth

2015-08-01

In the 1920s and 1930s, the parent education movement opened doors for many female psychologists and other child development professionals by providing training and jobs. Female experts in the parent education movement spread the emerging "gospel of child development" to other women-mothers-in a variety of formats. Although psychologists like John B. Watson advocated traditional definitions of motherhood focusing on role adjustment, there is evidence that women psychologists and parent educators introduced ways of thinking about family life that challenged tradition, encouraging role expansion and self-fulfillment. We explore examples provided by women at the Minnesota Institute of Child Welfare who produced radio programs on child rearing. Starting in 1932, advice about child rearing was embedded within stories featuring a fictional family, the Bettersons. The family narrative format provides an opportunity to identify implicit (and sometimes explicit) values and norms informing prescribed roles for mothers, fathers, and children. Analysis suggests that gender roles were shifting in more egalitarian directions, with an awareness of new identity options for both women and men. We explore implications for evaluating the impact of female experts involved in the parent education movement. (c) 2015 APA, all rights reserved).

Strategic framing of public messages about HIV pre-exposure prophylaxis (PrEP) may influence public support for policies and programs affecting access. This survey study examined how public attitudes toward PrEP differed based on the social group PrEP was described as benefiting ("beneficiary") and the moderating effect of prejudice. Members of the general public (n = 154) recruited online were randomly assigned to three beneficiary conditions: general population, gay men, or Black gay men. All participants received identical PrEP background information before completing measures of PrEP attitudes (specifying beneficiary), racism, and heterosexism. Despite anticipating greater PrEP adherence among gay men and Black gay men and perceiving PrEP as especially beneficial to the latter, participants expressed lower support for policies/programs making PrEP affordable for these groups vs. the general population. This disparity in support was stronger among participants reporting greater prejudice. Inclusive framing of PrEP in public discourse may prevent prejudice from undermining implementation efforts.

Studies further indicate that this reduces patient satisfaction levels, lengthens hospital stays, and increases cost. Hospitals are aiming to discharge patients earlier, and this can interfere with adequate pain management. Therefore, the pain service at Chelsea and Westminster Hospital has adapted to this changing model of care. An increasing body of evidence demonstrates that psychological factors are key components of patients’ pain experiences in both acute and chronic pain. Therefore, it is reasonable to suggest a clinical psychologist should be involved in inpatient pain management. This small study discusses three cases that highlight how patient care could be improved by including a clinical psychologist as part of the inpatient pain team. Two cases particularly highlight the active role of the psychologist in the diagnosis and management of common conditions such as fear and anxiety, along with other psychiatric comorbidities. The management therefore employed an eclectic approach adapted from chronic pain and comprising of behavioral, cognitive behavioral, and dialectical behavioral therapeutic techniques blended with brief counseling. The third case exemplifies the importance of nurse-patient interactions and the quality of nurse-patient relationships on patient outcomes. Here, the psychologist helped to optimize

2011-04-01

Interventions in extreme situations, such as natural or technological disasters, terrorist attacks or emergencies in general, take place in settings of great uncertainty and are always accompanied by extraordinary circumstances. For this reason, there are various processes related to implementing intervention protocols that must be carefully examined, including an evaluation of work scenarios, personnel selection, within-group relationships in work teams, decision-making processes, or certain peculiarities of burnout among emergency personnel. In the view of this author, an ad hoc review of the role of the organisational psychologist can highlight interesting analysis and performance possibilities that could make work in emergency and disasters contexts more effective. The aim of this paper is to provide an overview of the role of the organisational psychologist pre-and post-disaster. Furthermore, it supports the idea that professional profiles must be designed that take into account specific knowledge and skills, as well as certain aptitudes and values. © 2011 The Author(s).
