    2006-01-01

    Abstract Background Seasonal changes in pore water and sediment redox geochemistry have been observed in many near-surface sediments. Such changes have the potential to strongly influence trace metal distribution and thus create seasonal fluctuations in metal mobility and bioavailability. Results Seasonal trends in pore water and sediment geochemistry are assessed in the upper 50 cm of littoral kettle lake sediments. Pore waters are always redox stratified, with the least compressed redox str...

    Full Text Available Abstract Background Seasonal changes in pore water and sediment redox geochemistry have been observed in many near-surface sediments. Such changes have the potential to strongly influence trace metal distribution and thus create seasonal fluctuations in metal mobility and bioavailability. Results Seasonal trends in pore water and sediment geochemistry are assessed in the upper 50 cm of littoral kettle lake sediments. Pore waters are always redox stratified, with the least compressed redox stratification observed during fall and the most compressed redox stratification observed during summer. A 2-step sequential sediment extraction yields much more Fe in the first step, targeted at amorphous Fe(III (hydroxides (AEF, then in the second step, which targets Fe(II monosulfides. Fe extracted in the second step is relatively invariant with depth or season. In contrast, AEF decreases with sediment depth, and is seasonally variable, in agreement with changes in redox stratification inferred from pore water profiles. A 5-step Tessier extraction scheme was used to assess metal association with operationally-defined exchangeable, carbonate, iron and manganese oxide (FMO, organic/sulfide and microwave-digestible residual fractions in cores collected during winter and spring. Distribution of metals in these two seasons is similar. Co, As, Cd, and U concentrations approach detection limits. Fe, Cu and Pb are mostly associated with the organics/sulfides fraction. Cr and Zn are mostly associated with FMO. Mn is primarily associated with carbonates, and Co is nearly equally distributed between the FMO and organics/sulfide fractions. Conclusion This study clearly demonstrates that near-surface lake sediment pore water redox stratification and associated solid phase geochemistry vary significantly with season. This has important ramifications for seasonal changes in the bioavailability and mobility of trace elements. Without rate measurements, it is not possible to

This study investigates the impact of asylum interviews on the mental health in a sample of 40 traumatized asylum seekers. The comparison group consisted of refugees (N=10 that had not been invited to an asylum interview. Additionally, the moderating effects of trial-related variables such as perceived justice of the trial, stress of giving testimony, and stress of waiting for the asylum interview were examined. Method: Participants were assessed on average 10 days before (t1 and 16 days after (t2 the asylum interview. Chi-square tests for dichotomous and categorical variables were used to compare the descriptive statistics of the two groups. To investigate symptom changes from t1 to t2, paired t-tests were calculated. The magnitude of effects was measured by Cohen's effect size d within groups. Hierarchical regression analyses were conducted for demographic and trial variables predicting posttraumatic intrusions, avoidance, and hyperarousal. Results: Data showed a significant increase in posttraumatic intrusions and a significant decrease in posttraumatic avoidance and hyperarousal symptoms from t1 to t2. No significant symptom changes in the posttraumatic stress disorder subscales were found in the comparison group. The results of hierarchical regression analyses revealed perceived justice of the interview to predict the increase of intrusions and the number of experienced traumata and testimony stress to predict posttraumatic avoidance. Conclusions: The present findings underline the stressful impact of asylum interviews on traumatized refugees. They indicate that the asylum interview might decrease posttraumatic avoidance and trigger posttraumatic intrusions, thus highlight the importance of ensuring that the already vulnerable group of traumatized refugees needs to be treated with empathy during their asylum

  3. Resilience among asylum seekers living with HIV

    Full Text Available Abstract Background A small body of evidence demonstrates the challenges faced by migrant communities living with HIV but has yet to consider in-depth the experience of asylum seekers whose residency status is undetermined. The overall aim of our study was to explore the experiences of those who are both living with HIV and seeking asylum. This paper focuses on the stressors precipitated by the HIV diagnosis and by going through the asylum system; as well as participants’ resilience in responding to these stressors and the consequences for their health and wellbeing. Methods We conducted an ethnographic study. Fieldwork took place in the UK between 2008–2009 and included: 350 hours of observation at voluntary services providing support to black and minority ethnic groups living with HIV; 29 interviews and four focus group discussions with those who were seeking asylum and living with HIV; and 15 interviews with their health and social care providers. Data were analysed using the constant comparative method. Results There were three main stressors that threatened participants’ resilience. First, migration caused them to leave behind many resources (including social support. Second, stigmatising attitudes led their HIV diagnosis to be a taboo subject furthering their isolation. Third, they found themselves trapped in the asylum system, unable to influence the outcome of their case and reliant on HIV treatment to stay alive. Participants were, however, very resourceful in dealing with these experiences. Resilience processes included: staying busy, drawing on personal faith, and the support received through HIV care providers and voluntary organisations. Even so, their isolated existence meant participants had limited access to social resources, and their treatment in the asylum system had a profound impact on perceived health and wellbeing. Conclusions Asylum seekers living with HIV in the UK show immense resilience. However, their isolation

    This paper is written on behalf of the West Australian Branch of the Australasian Faculty of Public Health Medicine. As public health physicians, we feel it is important that public health professionals should contribute constructively to address the needs of a socially deprived, marginalised group with high rates of physical and psychiatric morbidity. Depending on the definition, there are between 18 and 48 million asylum seekers and refugees in the world. Most seek protection in neighbouring countries, largely in Africa and Asia, rather than coming to North America, Europe and Australasia. Contrary to popular belief, numbers of successful applications to Australia's humanitarian program have actually fallen. This article attempts to correct misperceptions and misapprehensions about the effect of asylum seekers on the public health. Public health professionals should lobby for changes to Govemment policy that at present leave asylum seekers vulnerable to a cycle of poverty, ill-health and limited access to health services.

    Directory of Open Access Journals (Sweden)

    Marina Matešić

    2014-04-01

    Full Text Available This article examines the changes towards more gender-sensitive interpretations of refugee status in international and national asylum laws and policies within the context of contemporary and historical global power relations. It also analyzes the changes in the language that can be found in the international UNHCR guidelines for the protection of women asylum seekers, U.S. national guidelines for assessing gender-related asylum claims, and recent U.S. court decisions assessing the gendered claims of women. Among the analyzed court cases, the focus is on the 2005 Mohammed case due to its problematic court decision and legal interpretations. Finding the Western countries’ instrumentalization of the international refugee protection system crucial for understanding the contemporary asylum system and women asylum seekers, the argument connects the historical conditions with the way in which the protection of women refugees from “cultural” gendered violence has been articulated in asylum politics in the U.S. The author’s overall findings are that international law, governmental organizations, and liberal women’s human rights NGOs have shaped the international and national legal protection of (women asylum seekers in such a way that it reproduces global inequalities in its representation of “Third World” women and their culture, uses women asylum seekers fleeing from violence for the purpose of exercising Western cultural superiority, and covers up the restrictive and racist Western asylum politics towards immigrants and asylum seekers.

    INTRODUCTION Asylum seekers face a wide array of challenges, including the need for a fair and just adjudication process. In the state of Georgia, the Atlanta Asylum Network addresses the needs of such individuals by providing them physical, psychological and gynecological assessments, the results of which are presented to the courts in the asylum appeal process. OBJECTIVE As a component of the Network's program evaluation, assess outcomes among asylum seekers using its services, as well as relation of outcomes to type of service provided, the individual's geographic origin and English language proficiency. METHODS A retrospective examination was conducted of program data gathered by the Network between 2003 and 2012. Subjects included asylum seekers who received assessments by the Network during this period. The primary variable of interest was the final case outcome, defined as determination of asylum status: granted, withholding of removal, administrative closure and prosecutorial discretion, denied or voluntary departure. Outcomes were subsequently collapsed into a single positive or negative outcome variable. Positive outcomes included asylum granted, removal withheld, administrative closure and prosecutorial discretion. Negative outcomes included asylum denied and voluntary departure. We conducted bivariate and multivariate analyses, relating final case outcomes to Network services, geographic origin and English language proficiency, among the key variables. RESULTS A total of 69 of 120 asylum seekers in the study had a known final case outcome, and of those, 63.8% (44) had a positive outcome; or 37% of the total number of asylum seekers (n = 120). Among the 20 who received 2 of the 3 types of assessment (physical, psychological, gynecological), 16 (80%) received a positive case outcome. Most persons with a known final outcome came from Africa (41), where 78% (32) of cases resulted positive. Asylum seekers not proficient in English were 2.4 times more likely

  8. Problems Faced by Mexican Asylum Seekers in the United States

    Full Text Available Violence in Mexico rose sharply in response to President Felipe Calderón’s military campaign against drug cartels which began in late 2006. As a consequence, the number of Mexicans who have sought asylum in the United States has grown significantly. In 2013, Mexicans made up the second largest group of defensive asylum seekers (those in removal proceedings in the United States, behind only China (EOIR 2014b. Yet between 2008 and 2013, the grant rate for Mexican asylum seekers in immigration court fell from 23 percent to nine percent (EOIR 2013, 2014b. This paper examines—from the perspective of an attorney who represented Mexican asylum seekers on the US-Mexico border in El Paso, Texas—the reasons for low asylum approval rates for Mexicans despite high levels of violence in and flight from Mexico from 2008 to 2013. It details the obstacles faced by Mexican asylum seekers along the US-Mexico border, including placement in removal proceedings, detention, evidentiary issues, narrow legal standards, and (effectively judicial notice of country conditions in Mexico. The paper recommends that asylum seekers at the border be placed in affirmative proceedings (before immigration officials, making them eligible for bond. It also proposes increased oversight of immigration judges.

    Asylum seekers often have complex medical needs. Little is known about the cultural competences health care providers should have in their contact with asylum seekers in order to meet their needs. Cultural competence is generally defined as a combination of knowledge about certain cultural groups, as well as attitudes towards and skills for dealing with cultural diversity. Given asylum seekers' specific care needs, it may be asked whether this set of general competences is adequate for the medical contact with asylum seekers. We explored the cultural competences that nurse practitioners working with asylum seekers thought were important. A purposive sample of 89 nurse practitioners in the Netherlands completed a questionnaire. In addition, six group interviews with nurse practitioners were also conducted. A framework analysis was used to analyse the data of the questionnaires and the interviews. From the analysis, several specific competences emerged, which were required for the medical contact with asylum seekers: knowledge of the political situation in the country of origin; knowledge with regard to diseases common in the country of origin; knowledge of the effects of refugeehood on health; awareness of the juridical context in the host country; ability to deal with asylum seekers' traumatic experiences; and skills to explain the host country's health care system. Apart from these cultural competences specific for the situation of asylum seekers, general cultural competences were also seen as important, such as the ability to use interpretation services. We conclude that insight into these cultural competences may help to develop related education and training for health care providers working with asylum seekers.

    The number of asylum seekers in Germany has increased dramatically in 2015. Their medical care includes the officially recommended vaccinations; yet, no detailed information on this is yet available in Germany. In light of the rising number of asylum seekers, we have developed a concept to facilitate their vaccination. This concept includes the coordination of different partners, the supply of vaccines and other materials through the local health office, and the cooperation with the local physicians' association. To evaluate and accelerate progress, we compared the number of vaccinations conducted by physicians independently of the vaccination concept with those conducted within the new concept. For the period of investigation, 2,256 new asylum seekers were temporarily accommodated in the facilities. The vaccination concept was applied in only some of the facilities. Twenty-eight percent of all asylum seekers (642) were vaccinated at least once; 89 % of the vaccinees (571) were vaccinated within the newly developed concept. In the facilities that were not included in this concept, only 6 % of the refugees were vaccinated, whereas in the facilities that were included up to 58 % were vaccinated. Even though the new concept has started successfully, further innovations are required to reach sufficient vaccination coverage among asylum seekers. In view of the large number of new asylum seekers expected, the adjustment and expansion of the new concept requires professional planning and coordination. Furthermore, additional resources are required.

  20. Should she be granted asylum? Examining the justifiability of the persecution criterion and nexus clause in asylum law

    Directory of Open Access Journals (Sweden)

    Noa Wirth Nogradi

    2016-10-01

    Full Text Available The current international asylum regime recognizes only persecuted persons as rightful asylum applicants. The Geneva Convention and Protocol enumerate specific grounds upon which persecution is recognized. Claimants who cannot demonstrate a real risk of persecution based on one of the recognized grounds are unlikely to be granted asylum. This paper aims to relate real-world practices to normative theories, asking whether the Convention’s restricted preference towards persecuted persons is normatively justified. I intend to show that the justifications of the persecution criterion also apply to grounds currently lacking recognition. My main concern will be persecution on the grounds of gender.The first section introduces the dominant standpoints in theories of asylum, which give different answers to the question of who should be granted asylum, based on different normative considerations. Humanitarian theories base their claims on the factual neediness of asylum-seekers, holding that whoever is in grave danger of harm or deprivation should be granted asylum. Political theories base their justifications on conceptions of legitimacy and membership, holding that whoever has been denied membership in their original state should be granted asylum. Under political theories, Matthew Price’s theory will be discussed, which provides a normative justification of the currently recognized persecution criterion. The second section provides a descriptive definition of persecution based on Kuosmanen (2014, and evaluates the normative relevance of the different elements of this definition based on the theories presented previously. The third section is devoted to the examination of the normative justifiability of the nexus clause’s exclusive list of the bases (grounds upon which persons might be persecuted. The section argues that while the clause does not recognize that persecution might be based on gender, in fact many women experience harms based on

    2013-08-01

    Erving Goffman's "Asylums" is a key text in the development of contemporary, community-orientated mental health practice. It has survived as a trenchant critique of the asylum as total institution, and its publication in 1961 in book form marked a further stage in the discrediting of the asylum model of mental health care. In this paper, some responses from a range of disciplines to this text, 50 years on, are presented. A consultant psychiatrist with a special interest in cultural psychiatry and mental health legislation, two collaborating psychotherapists in adult and forensic mental health, a philosopher, and a recent medical graduate, present their varying responses to the text. The editors present these with the hope of encouraging further dialogue and debate from service users, carers, clinicians, and academics and researchers across a range of disciplines.

    This paper will highlight one of the key findings of a qualitative study based on the analysis of in-depth interviews with 14 health visitors describing their experiences working with refugees and asylum seekers. Despite changes in government legislation to improve children's services in order to prevent harm to children, this recent study demonstrated that health visitors were working with the complexities of needs among refugees and asylum seekers related to safeguarding both children and vulnerable women. The health visitors often worked with families and individuals with no support from other professional services, they worked with failed asylum seekers who were unable to access other forms of support and they worked with women and children who were caught in a cycle of domestic abuse due to their immigration status. They were also working with families who would disappear from the systems in place to safeguard children.

    US policy on refugees was developed as an ad hoc response to the problem of displaced persons in Europe following the Second World War and quickly became a foreign policy tactic to be manipulated in the context of the Cold War political struggle. It was not until 1980 that the US formally adopted an asylee policy in legislative forum. That policy, too, was affected by the Cold War. The dismantlement of the Berlin Wall in 1989 and the subsequent collapse of the Soviet Union in 1991, however, have radically changed the dynamics of refugee and asylee issues. Refugee and asylee pressures are increasingly being linked with the broader worldwide issues of population growth, unbalanced economic development, and migration pressures. New refugee and asylum policies are required in the new world order which are not predicated upon the need to respond to communism. These policies must be reserved for truly persecuted individuals. The author discusses the creation of an asylum policy, mass asylum, and pending policy reforms. The refugee system provides a means of access for many people looking to escape the poverty, unemployment, and destitution of their homeland. Asylum policy is the most vulnerable element of refugee policy for exploitation. To alleviate the economic forces which lie at the core of asylum abuse will require more fundamental policies than the procedural changes currently under consideration by Congress or those proposed by President Clinton. Among them must be policies which promote family planning and provide the means for its practice; expand commitments to economic development assistance; and link trade access to the US marketplace and the receipt of foreign aid to the strict adherence of internationally specified human rights practices.

  12. Multimorbidity in adult asylum seekers: a first overview.

    Full Text Available PRINCIPALS: Over the last two decades, the total annual number of applications for asylum in the countries of the European Union has increased from 15,000 to more than 300,000 people. The aim of this study was to give a first overview on multimorbidity of adult asylum seekers. METHODS: Our retrospective Swiss single center data analysis examined multimorbidity of adult asylums seekers admitted to our ED between 1 January 2000 and 31 December 2012. RESULTS: A total of 3170 patients were eligible for the study; they were predominantly male (2392 male, 75.5% versus 778 female, 24.5. The median age of the patients was 28 years (range 28-82. The most common region of origin was Africa (1544, 48.7%, followed by the Middle East (736, 23.6%. 2144 (67.6% of all patients were not multimorbid.

Infectious diseases were most frequent in patients from Africa (6.6%, followed by the Balkans and Eastern Europe/Russia (each 3.8%. CONCLUSION: The health care problems of asylum seekers are manifold. More than 60% of the study population assessed in our study did not suffer from more than one disease. Nevertheless a significant percentage of asylum seekers is multimorbid and exhibits underlying psychiatric, infectious or chronic medical conditions despite their young age.

  13. 'Insane criminals' and the 'criminally insane': criminal asylums in Norway, 1895-1940.

    Science.gov (United States)

    Dahl, Hilde

    2017-02-01

    This article looks into the establishment and development of two criminal asylums in Norway. Influenced by international psychiatry and a European reorientation of penal law, the country chose to institutionalize insane criminals and criminally insane in separate asylums. Norway's first criminal asylum was opened in 1895, and a second in 1923, both in Trondheim. Both asylums quickly filled up with patients who often stayed for many years, and some for their entire lives. The official aim of these asylums was to confine and treat dangerous and disruptive lunatics. Goffman postulates that total institutions typically fall short of their official aims. This study examines records of the patients who were admitted to the two Trondheim asylums, in order to see if the official aims were achieved.

    Human rights abuses of women are ubiquitous throughout the world. Those perpetrated by governments entitle women to seek political asylum, and many women refugees do so in the United States. The asylum process often requires medical or psychological evaluations to corroborate women's reports of torture or other abuses.

    Full Text Available In the Indonesian West Java town of Cisarua, asylum seekers and refugees face prolonged periods of waiting in limbo. Australian government policies have contributed to the lengthy waiting times, particularly Operation Sovereign Borders. Those in protracted situations have found ways to ensure that during their time in Cisarua their basic needs are met and they demonstrate creativity and resilience in difficult circumstances. Education for children is a priority for asylum seeker and refugee communities and a learning centre developed by the community has provided hope for children and their families. The paper draws on the experiences of Author One during his waiting time in Cisarua and research conducted by Authors Two and Three in late 2013.

  16. Forensic dental investigations and age assessment of asylum seekers.

    Nuzzolese, Emilio; Di Vella, Giancarlo

    2008-06-01

    Age estimation is useful in forensic investigations to aid in the process of identifying unknown victims as well as living individuals. In many countries age estimation is commonly used to assist immigration authorities in deciding whether refugees or illegal migrants have reached that designated age that separates a juvenile from an adult. This is particularly important for the protection of unaccompanied minors. Italy is a country of great appeal for immigration as people from other Mediterranean countries can easily reach Italian coasts. In Italy, as in other western world countries, unaccompanied asylum seekers deemed to be under 18 face a very different path through the immigration system. They cannot be deported and are sent through a juvenile system where they have access to education programmes and may be granted a residence permit. The Section of Legal Medicine of the University of Bari was approached by Judges and Immigration Police with the question to assess the age of unaccompanied asylum seekers who claim to be below 18 years of age. The contribution of forensic odontologists for age estimation was recognised and since November 2006 age estimation of asylum seekers in Bari (Italy) relies on clinical and dental examination together with skeletal maturation as seen on radiographs of the left hand and wrist, the pelvis for iliac crests and root development and mineralisation of third molars as seen on an orthopantomogram.

  17. An Overview of Pending Asylum and Refugee Legislation in the US Congress

    Directory of Open Access Journals (Sweden)

    Melanie Nezer

    2014-05-01

    Full Text Available There has been no significant legislation related to the asylum process enacted in Congress in nearly a decade.  In 1996, the Illegal Immigration Reform and Immigration Responsibility Act (IIRIRA became law, rolling back protections for asylum seekers by including a one-year deadline for filing asylum applications, subjecting asylum seekers to “expedited removal” procedures, and expanding the detention of asylum seekers. In 2005, Congress enacted the REAL ID Act, which created additional legal barriers to asylum, including new requirements for proving an asylum claim. During the past several sessions of Congress, bills have been introduced that would make significant changes to the country’s asylum laws and refugee admissions program. This paper provides an overview of the pending legislation and the changes proposed.  This overview is instructive in understanding (1 which members of Congress have demonstrated interest and leadership in refugee and asylum issues; (2 which refugee and asylum reform issues have been of most interest to members of Congress in recent years; (3 the different approaches to refugee and asylum issues by members of Congress who have shown leadership on these issues; and (4 which provisions have been enacted, which have gained traction, and which remain pending without significant movement through the legislative process.While it is difficult to imagine in the current partisan climate how any asylum or refugee legislation could be enacted into law, some legislative provisions have been reintroduced over a number of sessions of Congress and some have a history of bipartisan support.  Legislation focused on a group of particular interest or concern to members of Congress could gain traction.  A more comprehensive legislative approach framed by the need generally to improve the system could be less effective, particularly in the context of the years-long stalemate on comprehensive immigration reform

    Children of asylum seekers are at risk for psychosocial problems because of their flight history and exceptional living circumstances. This study aims to assess the association of sociodemographic factors and asylum procedural factors with psychosocial problems of asylum seekers' children, and differences herein by informant (parents, teachers, and children). To this end, we obtained data on psychosocial problems among a random sample of 267 children aged 4 to 16, living in Dutch asylum seekers' centers, using the multi-informant Strength and Difficulties Questionnaire. The results show that the prevalence rate of psychosocial problems among asylum seekers' children was high. The occurrence was not associated with asylum-procedural variables but only with child-contextual factors such as mental health of the mother and leaving behind a parent in the country of origin. The associations varied in strength by informant. Therefore, preventive and supportive measures to improve psychosocial health of young asylum-seekers should concentrate on these contextual issues.

  11. Discursive Representations of Asylum Seekers and Illegal Immigrants in Ireland

    Directory of Open Access Journals (Sweden)

    Elaine Burroughs

    2013-12-01

    Full Text Available Migrants are often referred to as an all encompassing group of people and the “many faces of migration”, the variety of people, legalities and complexities involved, can be overlooked. The same can be said for non-EU migrants in the Irish context. Non-EU migrants (or those that are not Caucasian are generally viewed to be a distinct cohort of comparable migrants. Indeed, these migrants are often portrayed in a broadly negative way by key Irish institutions (such as the parliament or the media, and these representations impact upon how Irish society views non-EU migration and indeed migration in general. While Ireland is by no means the only European country in which this type of practice occurs, this paper aims to draw attention to generalized, inaccurate and misleading representations of non-EU migrants in Ireland, by specifically examining representations of asylum seekers and illegal immigrants. There can be an overlap in how these “types” of migrants are conceptualized and this paper therefore aims to develop an understanding of the implications involved for migrants categorized as an “asylum seeker” or an “illegal immigrant.” Furthermore, these topics are under-researched within the Irish context, yet they receive much political and public attention. At the same time however, this paper aims to challenge the labels assigned to non-EU migrants and the terminology that is used to define their identity so concretely. In the Irish context there is much confusion in relation to the multiple “faces” of non-EU migration, as a range of terminology is used to refer to them. This terminology is often used in an interchangeable manner, in an array of societal contexts. There is a consistent (whether this happens intentionally or unintentionally is debatable misuse of categories and migration terminology in Irish institutional discourses. Quite often those seeking asylum are referred to as illegal immigrants and vice versa

  12. Emergency mental health nursing for self-harming refugees and asylum seekers.

    Science.gov (United States)

    Procter, Nicholas G

    2005-09-01

    This article describes the structure and function of emergency mental health nursing practice for self-harming refugees and asylum seekers on Temporary Protection Visas. Emergency nurses working in accident and emergency departments or as part of crisis intervention teams will see self-harming refugees and asylum seekers at the very point of their distress. This clinical paper is intended to support nurses in their practice should they encounter an adult asylum seeker needing emergency mental health care. Practical strategies are highlighted to help mental health nurses assess, care, and comfort refugees and asylum seekers in this predicament. Mental health nurses should, where possible, work closely with asylum seekers, their support workers, and accredited interpreters and translators to ensure the appropriate use of language when dealing with mental and emotional health issues without further isolating the asylum seeker from appropriate services. To help strengthen continuity and integration of mental health supports for refugees and asylum seekers, well-resourced care must be experienced as coherent and connected. A coherent, interdisciplinary and team-orientated approach will synthesize different viewpoints to shape clinical practice and create workable solutions in local situations.

  13. Rediscovering the Concept of Asylum for Persons with Serious Mental Illness.

    Lamb, H Richard; Weinberger, Linda E

    2016-03-01

    Treating persons with serious mental illness is a complex and challenging endeavor. One intervention that has received little attention in recent years is the need for asylum. Asylum means a sanctuary, a place that lowers levels of stress and provides protection, safety, security, and social support, as well as an array of treatment services. The concept of "asylum" may have lost favor because it was equated with the abysmal conditions found in the state psychiatric hospitals of the past. Among the reasons persons with serious mental illness have been arrested and incarcerated is society's failure to provide adequate levels of asylum. With the release of tens of thousands of mentally ill inmates from state and federal jails and prisons, it is time to revisit this concept, not only for these persons but for those who have not been criminalized. Asylum can be found in various settings, including with family in the patient's home, in a board-and-care facility, or in a psychiatric hospital if necessary. Not all persons with a major mental illness are capable of achieving high levels of social and vocational functioning; however, living in a place that provides asylum can promote a higher quality of life. The value of asylum for many persons with serious mental illness should not be underestimated.

    2011-03-01

    Dress was integral to the ideals and practice of Staffordshire County Lunatic Asylum, an institution catering for all social classes. Lunatics' appearance was used to gauge the standard of care inside the asylum and beyond. Clothing was essential for moral treatment and physical health. It helped to denote social and institutional class: clothes were integral to paupers' admission; rich patients spent time and money dressing; for disturbed inmates and those who destroyed asylum attire, the consequence could be'secure dress', which was fundamental to therapeutics. Later, when an ethos of non-restraint was introduced, the superintendent used patients' appearance to propagate an image of his enlightened care.

    The Hungarian health care system faces new challenges with the unprecedented increased rate of migration. Asylum-seekers arriving are a heterogeneous group. Their health care needs vary depending on their country of origin and the quality of the health care they received prior to arrival, not to mention the impact of the migration process on their health. Described within this paper are the challenges an asylum seeker might face in obtaining care on arrival into the host country and the challenges clinicians face in providing that care. This review is designed to give health professionals the necessary knowledge to care for asylum-seekers in a culturally aware and clinically informed manner.

    2016-03-01

    The phenomenon of African asylum seekers in Israel is relatively new. The purpose of the study was twofold: (a) to investigate how the asylum seekers construct their life stories and (b) to discover which aspects of the constructed life stories can be taken into consideration by various mental health professionals when providing help to asylum seekers. In this study, we interviewed 16 asylum seekers residing in Israel using the narrative method. Based on holistic analysis, we collected three groups of stories: "Then see what course life takes in the future," "I'm not yet free," and "Open prison." In the discussion of the findings, we focus on the similarities and differences among the groups of stories, with reference to the role of the sociopolitical context and to the private and social self as part of the participants' well-being. We make implementation suggestions for mental health interventions.

    2014-12-01

    Hundreds of clinicians in the US conduct asylum evaluations, to document evidence of torture and persecution of people fleeing their home countries. Participating in these encounters puts clinicians at risk for vicarious trauma (VT). Little research addressed VT in physicians. Even less is known about VT among asylum evaluators. A survey was distributed to members of the asylum network of Physicians for Human Rights in Spring 2012. The majority (65%) of survey participants denied having experienced VT. However, being female, being a mental health professional and having performed a greater number of evaluations was associated with a higher likelihood of reporting VT. We present preliminary data about VT in asylum evaluators. Recruiters and trainers should make every effort to address the issue and educate their volunteers about means of identifying and managing symptoms. Formal and informal support services and resources should be developed and shared with volunteers.

    2013-01-01

    A significant number of asylum seekers who largely survived torture live in the United States. Asylum seekers have complex social and medical problems with significant barriers to health care access. When evaluating and providing care for survivors, health providers face important challenges regarding medical ethics and professional codes. We review ethical concerns in regard to accountability, the patient-physician relationship, and moral responsibilities to offer health care irrespective of patient legal status; competing professional responsibility toward society and the judiciary system; concerns about the consistency of asylum seekers' claims; ethical concerns surrounding involving trainees and researching within the evaluation setting; and the implication of broader societal views towards rights and social justice. We discuss contributing factors, including inadequate and insufficient provider training, varying and inadequate institutional commitment, asylum seekers' significant medical and social problems, and the broader health and social system issues. We review existing resources to address these concerns and offer suggestions.

    Full Text Available In this paper I would like to present Serbian migration policy concerning irregular migration and asylum in the context of the attempts of the Serbian state to become a member of the European Union. I would describe the history of the asylum system prior and after the implementation of the independent asylum system in Serbia in 2008. My presentation of the Serbian migration policy would be channelled by the analysis of some particular political issues, such as the externalization of the EU borders’ control, as well as some relevant elements of the European integration process, like visa liberalization. The second, more culturally specific dimension of the issue would be accessed through the demonstration of both legislative and public conceptualizations of the irregular migrants, asylum seekers and refugees in Serbia.

    Fauvel, Aude

    2015-07-01

    If one thinks medicine, madness and the past, one image immediately pops into mind: that of the mental asylum. Following the famous work by Michel Foucault, Madness and Civilization: A History of Insanity in the Age of Reason, many historians have thus considered that the medicalization of insanity in the modern age had mostly led to a "great confinement" and a greater segregation of all individuals deemed mentally unfit during the "asylum era': However, new research demonstrates that this classic narrative of the psychiatric past needs to be revised. It discloses that, ever since the 191h century, a whole other medical culture existed as a challenge to asylums, a culture that advocated the integration of the mad and fought to disassociate psychiatry from the dominant model of confinement all throughout the occidental world. This article aims at presenting the results of these historical works that depict another aspect of the psychiatric history, exploring "boarding out" practices, instead of asylum ones.

    Refugees seeking asylum are a particularly vulnerable population. It has been observed that among the most commonly-occurring disorders exhibited in this population, there is a high incidence of post-traumatic stress disorder, generalized anxiety disorder, and depression. These disorders may be linked to the difficult paths that refugees are forced to undertake, as well as to different traumatic events which are particularly destructive psychologically (deliberate physical, sexual and/or psychological violence, traumatic bereavements in the context of war, or social and political instability, socio-economic, familial or administrative difficulties), which compromise their view of their short-term futures. In the face of the weight of these life events, the question of the psychological resources of the individual is at the forefront of our understanding of mental health and the capacity to adjust to trauma. Our study aims to apprehend in a dynamic way, the different strategies used by asylum seekers in our western countries to adjust psychologically to traumatic and stressful events. The aim of this research is to study the links between mental health and anxious and depressive psychopathologies as well as the defensive modalities of these subjects. One hundred and twenty adult asylum seekers, living in refugee centres in Slovakia, France and Norway have agreed to participate in this study. We tried to assess the psychopathological disorders manifesting in these populations, notably PTSD, major depression and generalized anxiety disorder. Using the DSQ-60 we also tried to establish the links between the psychopathologies observed in this population and the defence mechanisms employed. Our results reveal that 60% of subjects do indeed suffer from psychopathological disorders with an important comorbidity of PTSB and depression (64.2%). Furthermore, the seriousness of the symptoms is correlated with less adaptive defence mechanisms (a higher incidence of defence

    Full Text Available Objective:This study aimed to determine prevalence of hepatitis B, C and HIV/AIDS in asylum seekers in Istanbul, Turkey. Methods: The data about asylum seekers who applied in Istanbul between March 2008 and March 2010 were evaluated retrospectively. Demographic features and markers of blood borne infections (HBsAg, anti-HCV and anti-HIV results of asylum seekers were reviewed. Results: In total 3043 asylum seekers were included into the study. The leading origin countries of the refugees were from Afghanistan, Turkmenistan and Azerbaijan and majority of them (2328 people, 77% were male. The young adults between 25 and 45 years constituted the most crowded group. Overall prevalence of HCV, HBsAg and HIV/AIDS were 12.2%, 5.9% and 0.7%, respectively. The highest seropositivity rate for anti-HCV, HBsAg and anti-HIV were found in Georgian males (47.1%; in Moldovan males (13.2% and in Somali males (3.1%, respectively. Conclusion:Mostly asylum seekers who have migrated to our country were young adult males from Asia. The highest prevalence rate of HCV was found in Georgian males. Therefore, the increased potential of migration to our country along the recent years necessitates development of an appropriate health approach concerning asylum seekers.

    Employees and volunteers often feel insecure about the potential transmission of infectious diseases when taking care of asylum seekers. It could be shown that overall only a minor risk of infection emanates from asylum seekers. However, aspects of occupational health and vaccination should be kept in mind.Besides the standard vaccination the Standing Committee on Vaccination (STIKO) recommends for occupational indication, which is given for employees and volunteers in asylum facilities, vaccination against hepatitis A, hepatitis B, polio (if the last vaccination was more than 10 years before) as well as influenza (seasonal).According to the German Occupational Safety and Health Act taking care of the employer has to determine which exposures might occur at the workplace (risk assessment) and define necessary protection measures. Depending on task and exposure when taking care of asylum seekers different acts (e. g. biological agents regulation) and technical guidelines for the handling biological agents (e. g. TRBA 250 or TRBA 500) have to be applied.The Bavarian Health and Food Safety Authority (LGL) has published several information sheets regarding "asylum seekers and health management" for employees and volunteers from the non-medical as well as the medical area (www.lgl.bayern.de search term "Asylbewerber"). With theses publications insecurities in taking care of asylum seekers should be prevented. Furthermore the employer gets support in the implementation of legal obligations to ensure occupational safety for the employees.

On the other side, Macedonia is struggling with an influx of refugees, finding itself in a status quo position, even looking as it does not know how to solve the situation. Migrants were killed on railways every day not being able to use any kind of public transportation; their smuggling became a normal business for organized crime groups; Macedonian citizens started to earn money on refugees’ misfortune. The paper using the comparative method and document analysis, gives an overview of the EU’s legislation in the area, its improvement and current impact on things, all of it concluded with the Macedonian legal solutions regarding asylum and authors’ recommendations.

  10. Narrative survival: personal and institutional accounts of asylum confinement.

    Science.gov (United States)

    Hanganu-Bresch, Cristina; Berkenkotter, Carol

    2012-01-01

    This essay has been conceptually eclectic in that we have integrated concepts from genre theory and discourse analysis. In our interpretation of Merivale and Marshall's narratives, we have also drawn upon Frye's Anatomy of criticism, a canonical text in literary genre theory. Such an eclectic approach seems warranted by both the contextual and textual features of Merivale's and Marshall's narratives, and in particular by Merivale's use of Mennipean satire with its encyclopedic detail. In our discussion of Merivale and Marshall's Admissions Records we have drawn on speech act theory to suggest that the Order (to admit a patient), the two medical certificates that follow, and finally, the notice to admit a patient constitute a constellation of texts, a genre suite, with a powerful illocutionary force. These texts are the prelude to and the means of confinement; they are both act and process. At the heart of our comparison of the asylum records of Merivale and Marshall with their "survivor narratives" is our analytic conclusion that the Ticehurst case histories can be said to constitute a linear "chronicle" of what Hayes Newington, the writer of the two case histories observed and inferred about his two patients. As chronicles, the Ticehurst Asylum case histories are linear representations or realistic accounts. As such, these archival documents provide a genuine insight into the "ways that that reality offers itself to perception". The institutional accounts exist in--and mark a--"flat time," equalized by each dated entry depicting the writer's mechanical act of observing/noting in brief, stereotypical sentences, e.g., "Patient is better [or, conversely, no] better today." We dubbed this metronomic time: beating regularly and evenly, flattening out the individual trajectories of each patient's illness. Metronomic time is normative. Each beat is calculated precisely to be the same as next. The dispassionate nature of clinical observations and the metronymic rhythms of

    Reuber, M

    1995-09-01

    250 years ago, the satirical writer and clergyman Jonathan Swift from Dublin (1667-1745) founded the first Irish lunatic asylum. Rejecting the theories put forward by the English philosopher Thomas Hobbes and the doctor Thomas Willis, he was influenced by the ideas of the Scottish doctor and the "enlightened" thinker John Locke. Swift's St. Patrick's Hospital did not, however, realise a new philosophical concept: architecture and therapeutic approach of the new institution were clearly modelled on the much older Hospital of St. Mary of Bethlehem ( = Bedlam). Despite its conservative conceptual basis, the first institution dedicated to the mentally ill and intellectually subnormal in Ireland became a starting point for the apparantly unstoppable expansion of the, at one time, most comprehensive asylum system in the world. After Swift's Hospital had been enlarged twice at the tax-payers' expense (1778, 1793), the administration decided to relieve the institution by erecting the Richmond Asylum (1810), the first public asylum in Ireland. When this establishment also became overcrowded, in 1817, legislation was passed which led to the establishment of the oldest system of public asylums in Europe.

    The number of asylum seekers arriving in Germany has increased rapidly since 2014 and cases of vaccine-preventable diseases at reception centres were reported. Asylum seekers 12 years and older arriving in Lower Saxony were serologically screened for antibodies against measles, rubella and varicella between November 2014 and October 2015. We calculated the seroprevalence from the screening data by disease, country of origin and age group and compared them to literature-based herd immunity thresholds in order to identify immunisation gaps. In total, 23,647 specimens were included in our study. Although the vast majority of asylum seekers tested positive for antibodies against measles, rubella and varicella, the seroprevalences were not sufficient to ensure herd immunity. The seroprevalences varied substantially between countries of origin and increased with age. Immunisation of asylum seekers against measles, rubella and varicella is needed and the detailed information on seroprevalences among subgroups of asylum seekers can be used for targeted immunisations at reception centres.

  1. Credibility Assessments as 'Normative Leakage': Asylum Applications, Gender and Class

    Directory of Open Access Journals (Sweden)

    Hanna Wikström

    2013-10-01

    Full Text Available Based on the assumption that credibility assessments function as 'normative leakage' within the asylum process, we analyse how narratives of gender and class are articulated, rendered meaningful, or silenced in credibility assessments. Two cases concerning male applicants are selected in order to illustrate these processes. In relation to the existing concepts of internal/external credibility, we wish to introduce the concept of social credibility, which focuses on how the assessors read different socio-cultural narratives. While previous research has shown that the postcolonial will to protect women favours women as victims of patriarchal cultures, we wish to point out the continuity of this line of argumentation in relation to male and female applicants by adopting a theoretical generalization: male applicants instead become situated at the other end of the spectrum of postcolonial notions of modernity as non-victims, victims of other circumstances or perpetrators. We argue that these processes are accentuated in relation to credibility assessments. In order to prevent processes of social exclusion and to enhance inclusive practice, authorities need to acknowledge the 'normative leakage' associated with the assessment process.

  2. Do supranational EU institutions make a difference? EU asylum law before and after 'communitarization'.

    Science.gov (United States)

    Ripoll Servent, Ariadna; Trauner, Florian

    2014-09-14

    This article examines whether the empowerment of the European Union's (EU) supranational institutions has had an impact on the development of EU asylum. By systematically investigating EU asylum law before and after 'communitarization', it argues that its 'policy core' has maintained a high degree of continuity. An advocacy coalition under the leadership of the interior ministers managed to co-opt pivotal actors in the newly empowered European Commission and European Parliament. By contenting themselves with changes of secondary order, these EU institutions accepted and institutionalized the restrictive and weakly integrated core of EU asylum set by the Council in the first negotiation round. Their role and decisions were driven not only by the negotiation dynamics and political expediency, but also by new inter- and intra-institutional norms fostering consensual practices.

  3. Mental health and legal representation for asylum seekers in the ‘legacy caseload’

    Full Text Available This article examines processes and challenges attendant upon an asylum seekers arriving by boat to Australia obtaining legal assistance for their claims. The authors set about explaining the experiences of asylum seekers in the ‘legacy caseload’ who have been waiting for around 4 years to have their protection claims assessed. The provision of legal assistance for this group will be essential to ensuring that the refugee status determination process is fair and allows asylum seekers to understand and participate more fully in the process.  It describes the complex interplay between legal assistance to support refugee claims and the way those making claims inevitably struggle to understand, engage and participate in the process. Recent changes to the assessment of claims combined with a reduction in funding for legal assistance create significant hurdles and combine to compound existing stress and adversity.

  4. Postpartum depression in refugee and asylum-seeking women in Canada: A critical health psychology perspective.

    2015-05-01

    Canada has one of the world's largest refugee resettlement programs in the world. Just over 48 percent of Canadian refugees are women, with many of them of childbearing age and pregnant. Refugee and asylum-seeking women in Canada face a five times greater risk of developing postpartum depression than Canadian-born women. Mainstream psychological approaches to postpartum depression emphasize individual-level risk factors (e.g. hormones, thoughts, emotions) and individualized treatments (e.g. psychotherapy, medication). This conceptualization is problematic when applied to refugee and asylum-seeking women because it fails to acknowledge the migrant experience and the unique set of circumstances from which these women have come. The present theoretical article explores some of the consequences of applying this psychiatric label to the distress experienced by refugee and asylum-seeking women and presents an alternative way of conceptualizing and alleviating this distress.

    2012-07-01

    The objective of this study was to determine the barriers to effective practice that health visitors experience when working with refugees and asylum seekers. This was a qualitative study based on the analysis of in-depth interviews with a purposive sample of 14 health visitors describing their experiences working with refugees and asylum seekers. These were analysed using the Framework process, a thematic matrix-based analytical method. The findings identified that the barriers to effectiveness for health visitors when working with refugees and asylum seekers were underpinned by ineffective use of services and stretched resources. The results imply that commissioners of services need to have an understanding of these barriers to commission effectively.

  6. The Moral Economy of Lying: Subjectcraft, Narrative Capital, and Uncertainty in the Politics of Asylum.

    Science.gov (United States)

    Beneduce, Roberto

    2015-01-01

    Based on narratives of asylum-seekers from sub-Saharan Africa in northern Italy, in this article I analyze the narrative strategies used by immigrants to meet the eligibility criteria established by asylum law. For many of them, this means "arranging" biographical details within what I call "a moral economy of lying." The first question I discuss is what types of experience and 'subject positions' these narrative strategies reveal or generate. I then examine the arbitrariness and the bureaucratic violence of the asylum evaluation process, and the role of these procedures in the making of nation-language and current technologies of citizenship. Finally, I consider the politics of testification, recognition, and memory these discourses and practices combine to shape. I analyze these issues from an historical point of view of the politics of identity, truth, and falsehood as imposed in a recent past by colonizers onto the colonized.

  7. The Relationship Between Post-Migration Stress and Psychological Disorders in Refugees and Asylum Seekers.

    Li, Susan S Y; Liddell, Belinda J; Nickerson, Angela

    2016-09-01

    Refugees demonstrate high rates of post-traumatic stress disorder (PTSD) and other psychological disorders. The recent increase in forcible displacement internationally necessitates the understanding of factors associated with refugee mental health. While pre-migration trauma is recognized as a key predictor of mental health outcomes in refugees and asylum seekers, research has increasingly focused on the psychological effects of post-migration stressors in the settlement environment. This article reviews the research evidence linking post-migration factors and mental health outcomes in refugees and asylum seekers. Findings indicate that socioeconomic, social, and interpersonal factors, as well as factors relating to the asylum process and immigration policy affect the psychological functioning of refugees. Limitations of the existing literature and future directions for research are discussed, along with implications for treatment and policy.

    Asylum seekers constitute a particularly vulnerable group. Not only is their physical and mental health exposed to multiple stresses, but also their access to health care in Germany is legally restricted. Up to now, there is very limited scientific literature investigating the health-outcomes of asylum seekers in Germany. The aim of this study was to provide prevalence data on the morbidity and vaccination status of asylum seekers in a medium-sized German city. We used a structured questionnaire in a cross-sectional study on 214 adult asylum seekers (182 males, 24 females, 8 unknown) in Halle, Germany, 2015. The questionnaire inquired about the respondent's self-reported physical health and vaccination status and assessed their mental health using the Hopkins-Symptom-Checklist-25 and the Harvard Trauma Questionnaire. Pain (37.9 %) and psychological illness (depression: 54.7 %, anxiety disorder: 40.2 %; post-traumatic stress disorder: 18.2 %) were the most prevalent complaints. Among asylum seekers with psychological complaints, co-morbidity was high (64.2 % had more than one psychological disease). 5.6 % of the respondents mentioned suicidal thoughts. The prevalence of chronic diseases was low. We suggest interventions to improve asylum seekers' health on two levels: first, the obligatory initial medical examination after the refugees' arrival at the reception centre should be complemented with questions related to the vaccination status and the most common complaints including pain and psychological diseases. Second, medical infrastructure should be expanded to better serve the needs of culturally and linguistically diverse patient populations, so that those screened positive can be referred for early diagnosis and treatment.

    2017-03-01

    This paper uses the unique collection of Scottish outsider art, labelled Art Extraordinary, as a window into the often neglected small spaces of asylum care in the early twentieth century. By drawing upon materials from the Art Extraordinary collection and its associated archives, this paper demonstrates the importance of incorporating small and everyday spaces of care - such as gardens, paths, studios and boats - into the broader historical narratives of psychiatric care in Scotland. Examples of experiential memorialization and counterpoints to asylum surveillance culture will be illuminated. The significance of using 'outsider' art collections as a valuable source in tracing geographical histories will be highlighted.

    While feminist arts-based projects have gained legitimacy, theory guiding the use of visual images in field research has lagged. Drawing on psychoanalytic-feminist theory and participatory action research methods, the article presents a study carried out with women refugee and asylum seekers that focuses on their experiences in seeking a place of safety in the United Kingdom. The aim was to produce through photography and videography a collective account of asylum as a daily process. In discussing the study, the authors provide a psychoanalytic framework for working through ethical, political, and methodological dilemmas in the use of visual imagery in feminist research.

  12. The laboratory and the asylum: Francis Walker Mott and the pathological laboratory at London County Council Lunatic Asylum, Claybury, Essex (1895-1916).

    Science.gov (United States)

    Buklijas, Tatjana

    2017-03-01

    London County Council's pathological laboratory in the LCC asylum at Claybury, Essex, was established in 1895 to study the pathology of mental illness. Historians of psychiatry have understood the Claybury laboratory as a predecessor of the Maudsley Hospital in London: not only was this laboratory closed when the Maudsley was opened in 1916, but its director, Frederick Walker Mott, a champion of the 'German' model in psychiatry, was instrumental in the establishment of this institution. Yet, as I argue in this essay, for all the continuities with the Maudsley, the Claybury laboratory should not be seen solely as its predecessor - or as a British answer to continental laboratories such as Theodor Meynert's in Vienna. Rather, as I show using the examples of general paralysis of the insane and 'asylum colitis', the Claybury laboratory is best understood as an attempt to prevent mental illness using a microbiological model.

    The aim was to assess change in activities of daily living (ADL) ability amongst asylum seekers and if there were any difference between tortured and non-torture following a 10 months post-arrival period, and if self-reported health and exposure to torture were factors related to change in ADL-ability. The study was a combined baseline, follow-up correlational study amongst individuals from Afghanistan, Iran and Syria, living in Danish asylum centers. Forty-three persons aged 20-50, were invited and participated in the baseline study. Twenty-two were still in asylum center at the follow-up and 17 of them participated. ADL-ability was measured using Assessment of Motor and Process Skills and questionnaires about exposure to torture, self-reported mental health and pain. ADL motor and process measures, well-being and self-rated health declined from baseline to follow-up. Measures of pain and depression increased. Exposure to physical torture and change in ADL motor (r = 0.525) measures were associated, as well as change in current pain and change in ADL process (r = 0.525) measures. Due to preponderance of torture survivors analysis of group difference was not applicable. Health care workers should be aware of ADL concerns and exposure to torture in this population to best address their needs within rehabilitation settings.

  17. U.S. grants political asylum to woman who fled female genital mutilation.

    Science.gov (United States)

    1996-06-28

    Fauziya Kasinga fled to the US from Togo in 1994 at the age of 17 years after an aunt forced her to marry a 45-year-old man with three wives. From the time of her arrival to the US in December 1994 to April 24, 1996, Kasinga was detained at two correctional facilities awaiting a decision by the US Board of Immigration Appeals (BIA) on her request for political asylum. That asylum was granted in a 11-1 decision issued on June 13 on the grounds of Kasinga's fear of being forced to undergo female genital mutilation (FGM) if sent back to Togo. This is the first time that the BIA has ruled that FGM can be grounds for asylum. 50% of women in Togo are estimated to have undergone FGM. The BIA decided that the young woman met the criteria for receiving refuge because she is a member of a particular social group, the unmutilated women of the Tchamba-Kunsuntu tribe who face but oppose FGM, which has a well-founded fear of persecution which is country wide. Moreover, Kasinga's husband has influence with the police in Togo, a rather small country. This decision not only sets precedent with regard to FGM, but also is the first gender-based asylum claim to be considered since the Immigration and Naturalization Service revised its guidelines in May 1995 to cover such persecution.

  7. People Seeking Asylum in Australia and their Access to Employment: Just What Do We Know?

    Directory of Open Access Journals (Sweden)

    Caroline Fleay

    2016-07-01

    Full Text Available Public and political claims about the employment of people from a refugee background in Australia do not always reflect the research findings in this area. For example, recent claims by a senior Coalition Government Minister about people seeking asylum who arrived to Australia by boat during the previous Labor Government’s terms in office (2007-13 posit that many have limited employment prospects. However, given there is little research or government reporting on the experiences of asylum seekers who arrived during this time, and none that focuses specifically on their employment, there is no evidence to support this. A review of research on the employment experiences of people from a refugee background, and Australian policies, suggests a more nuanced picture. This includes research that found while initially people from a refugee background are more likely to be unemployed, have temporary jobs and lower incomes than other newly arrived immigrants, second-generation refugees have higher levels of labour market participation than the general population. Research also highlights that refugees may experience a range of barriers to accessing employment, including discrimination, and a review of Australian policies indicates these are likely to have exacerbated some of these barriers for asylum seekers who arrived to Australia by boat. In addition, given previous findings that public attitudes can be influenced by representations made in public and political discourses, the public statements of senior Ministers may be further deepening barriers to accessing employment faced by asylum seekers who arrived by boat.

    Science.gov (United States)

    Sacristán, Cristina

    2011-01-01

    The present article analyzes a campaign by the Mexican government, among the public and the medical profession, to disseminate a health care reform that culminated with the opening of thirteen Farms for the mentally ill and the ideological abolition of the insane asylum in the sixties of the twentieth century. To do this, renowned psychiatrists who held public positions built a black legend over the most emblematic insane asylum of the country, pointing out as the main cause of failure the constraint to which patients were subjected. In doing so, they resembled the mental hospital to a prison and the insane to a social threat, because they reduced that institution's function and denied the many experiences that would ?t in it: a place of confinement and refuge, a therapeutic and knowledge production space. Even though Mexican psychiatry was professionalized in the space of the asylum, the State wanted to erase the memory of that past to suggest the establishment of a new era in mental health, where the patients would no longer be subject to any restrictions which could curtail their freedom. Overcoming the asylum model meant creating "open door" therapeutic alternatives, but the decision was to distort the past to exalt the future.

  9. Sovereign Borders: The Militarisation of Asylum Seeker Discourses in Australian Television News Media

    Directory of Open Access Journals (Sweden)

    Leicha Stewart

    2016-07-01

    Full Text Available While the democratic paradigm of governance and its constituent political processes are well established in Australia, consistently negative media representations of people seeking asylum may be viewed as justification for institutional decisions allowing continued punitive treatment of people seeking asylum on Australian shores. Historically, notions of Australian sovereignty exist as a changing discourse with reference to land claims and the Australian Indigenous population (O’Dowd 2011; Due 2008. However, in terms of contemporary political claims about Australia’s need to enforce border protection policies, notions of sovereignty are consistently framed through the themes, images and language of military discourses. Media scholar, John Street suggests that although there is disagreement about whether specific political outcomes can be attributed to press influence, the role of television in politics has been more comprehensively established as shaping broader world views in regards to ideas, values and practices that are considered ‘common-sense’ (Street 2011; Craig 2013. This paper argues that the increasing role of the military in the treatment and processing of people seeking asylum may be justified, through repetitive negative media representations of asylum seekers which secures public support for such practices, thereby undermining the very principles of the democratic paradigm, and indeed the role of the media or ‘fourth estate’(Schultz 1998 in a functioning democracy.

  10. Asylum Seekers and Resettled Refugees in Australia: Predicting Social Policy Attitude From Prejudice Versus Emotion

    Directory of Open Access Journals (Sweden)

    Lisa K. Hartley

    2015-07-01

    Full Text Available While most of the world's refugees reside in developing countries, their arrival to western countries is highly politicised, giving rise to questions about the types of entitlements and rights that should, or should not, be granted. In this study, using a mixed-methods community questionnaire (N = 185, we examined attitudes towards social policies aimed at providing assistance to two categories of new arrivals to Australia: resettled refugees (who arrive via its official refugee resettlement program and asylum seekers (who arrive via boat and then seek refugee status. Social policy attitude was examined as a consequence of feelings of anger, fear, and threat, as well as levels of prejudice. Participants felt significantly higher levels of anger, fear, threat, and prejudice towards asylum seekers compared to resettled refugees. For both resettled refugees and asylum seekers, prejudice was an independent predictor of more restrictive social policy attitudes. For resettled refugees, fear and perceived threat were independent predictors for more restrictive social policy whereas for asylum seekers anger was an independent predictor of restrictive social policy. The qualitative data reinforced the quantitative findings and extended understanding on the appraisals that underpin negative attitudes and emotional responses. Practical implications relating to challenging community attitudes are discussed.

    Assessing the skin of asylum seekers, immigrants, migrant workers, tourists or even locals who return from abroad, can be a confronting task due to the possibility of such people having non-autochthonous diseases. Primary-care physicians and dermatologists need to have a systematic approach in the assessment of such dermatoses. This article describes an interesting case of possible kerosene-induced and diesel-induced skin injury in an asylum seeker arriving on a boat. Dermatological conditions in asylum seekers and a suggested template for skin assessment are discussed.

    BACKGROUND: Adult refugees and asylum seekers living in Western countries experience a high prevalence of mental health problems, especially post traumatic stress disorder (PTSD), depression and anxiety. This study compares and contrasts the prevalence of health problems, and potential risk factors as well as the utilisation of health services by asylum seekers and refugees in the Irish context. METHODS: Cross sectional study using validated self reported health status questionnaires of adult asylum seekers (n = 60) and refugees (n = 28) from 30 countries, living in Ireland. Outcome measures included: general health status (SF-36), presence of PTSD symptoms and anxiety\\/depression symptoms. Data on chronic conditions and pre or post migration stressors are also reported. The two groups are compared for utilisation of the health care system and the use of over the counter medications. RESULTS: Asylum seekers were significantly more likely than refugees to report symptoms of PTSD (OR 6.3, 95% CI: 2.2-17.9) and depression\\/anxiety (OR 5.8, 95% CI: 2.2-15.4), while no significant difference was found in self-reported general health. When adjusted by multivariable regression, the presence of more than one chronic disease (OR 4.0, 95%CI: 1.3-12.7; OR 3.4, 95% CI: 1.2-10.1), high levels of pre migration stressors (OR 3.6, 95% CI: 1.1-11.9; OR 3.3, 95% CI: 1.0-10.4) or post migration stressors (OR 17.3, 95% CI: 4.9-60.8; OR 3.9, 95% CI: 1.2-12.3) were independent predictors of self reported PTSD or depression\\/anxiety symptoms respectively, however, residence status was no longer significantly associated with PTSD or depression\\/anxiety. Residence status may act as a marker for other explanatory variables; our results show it has a strong relationship with post migration stressors (chi2 = 19.74, df = 1, P < 0.001).In terms of health care utilisation, asylum seekers use GP services more often than refugees, while no significant difference was found between these groups

    Many clinicians perform asylum evaluations yet no studies describe the motivation to perform them or their perceived rewards. The number of asylum seekers in the US is increasing and more clinicians are needed as evaluators. A survey to an asylum evaluators' network asked participants to qualitatively reflect on their experience and motivation. Answers were analyzed for themes and sentiment. Respondents cited commitment to humanistic and moral values, noted personal and family experiences, having skills, expertise, and career interests as drivers. They found the experience very rewarding personally and professionally, and in their perceived benefit to asylees. Negative sentiment was less frequent and centered on emotions related to client narratives. Process-oriented frustrations were also noted. This is the first published study describing clinicians' motivation and experience with asylum evaluations. It may illuminate clinicians' drive to volunteer, and serve as a resource for organizations for recruitment and education.

  2. Asylum migration and the construction of the European Common Foreign and Security Policy: evidence from the Greek case

    Full Text Available This article examines how the recent evolution of asylum migration has affected the construction of the European Common Foreign and Security Policy (EU-CFSP, taking the Greek case during the 2001-2012 period as a starting point. With this in mind, the normative progress of the EU-CFSP facing the reception of asylum seekers in Greece is analyzed, under the scope of what Barry Buzan and Ole Waever would call Securitization Process. Both legal and political frameworks on asylum migration in Greece and in the European Union are approached, in the context of the evolution of the EU-CFSP in three main areas: Neighborhood Policy, Development and Cooperation Policy, and Human Rights Protection. The conclusión points toward the partial influence of asylum migration in the configuration of the UE-CFSP during the studied period.

  3. Hydrology of Hunters Lake, Hernando County, Florida

    The size and shape of Hunters Lake, Florida has been significantly altered by development of the surrounding Spring Hill residential community. The lake is the largest in Hernando County, enlarged by lakeshore excavation and connection to nearby ponds to an area of 360 acres at an average stage of 17.2 ft above sea level. Hunters Lake is naturally a closed lake, but development of Spring Hill has resulted in a surface water outflow from the lake in its southwest corner. Inflow to the lake could occur on the east side during extreme high-water periods. The karst terrain of the Hunters Lake area is internally drained through permeable soils, depressions, and sinkholes, and natural surface drainage is absent. The underlying Floridan aquifer system is unconfined except locally near coastal springs. Flow in the groundwater system is to the west regionally and to the southwest in the immediate area of Hunters Lake. Water level gradients in the groundwater system increase from 1.4 ft/mi east of the lake to about 8 ft/mi southwest of the lake. Hunters Lake is hydraulically connected to the groundwater system, receiving groundwater on the northeast side and losing water to the groundwater system on the southwest side. This close relationship with the groundwater system is demonstrated by graphical and numerical comparison of Hunters Lake stage with water levels in nearby groundwater sites. During 1965-84, the stage of Hunters Lake fluctuated between 12.48 and 20.7 ft above sea level. Because area lakes are all directly affected by groundwater levels, they also show a close relationship with water levels in Hunters Lake. Analysis of water quality data for Hunters Lake indicates that the water of the lake is a soft calcium bicarbonate type with ionic concentrations higher than in water from nearby shallow wells and lower than in water from the Upper Floridan aquifer. Samples collected in 1981-1983 indicate slightly higher levels of ionic concentration than in 1965

  4. The Principle of Non-Refoulement and Access to Asylum System: Two Sides of the Same Coin

    Full Text Available The European Union and other countries on the Balkan route for migrants have recorded a large increase in the number of asylum seekers. In parallel with the increased number of refugees trying to enter the territory of the EU, measures for migration management have tightened, and the right to asylum at the level of the Member States has been interpreted more and more restrictive. Search for protection from persecution has become a reason for closing borders and disabling access to territory and asylum system. However, access to asylum system is the first step in the realization of the right to asylum as guaranteed by international, European and national law. In addition to allowing access to territory and asylum system, which implies an obligation of states to accept refugees in order to confirm the need for international protection in a fair and efficient procedure, the states are obliged to respect the principle of non-refoulement. The aim of this paper is to clarify the connection between providing access to asylum system and respect for the principle of non-refoulement. Analysis in the paper was done by legal-dogmatic method of research and interpretation of legal acts and other authorities, as well as of UNHCR relevant recommendations and documents. The assumption is that without the provision of access to territory and asylum system the principle of non-refoulement cannot be respected. Apart from the international refugee law and doctrinal interpretations, it derives from the practice of the European Court of Human Rights regarding the prohibition of torture or other inhuman treatment or punishment guaranteed by the Convention for the Protection of Human Rights and Fundamental Freedoms. The conclusion is that the states must take into account international and European standards regarding the protection of the principle of non-refoulement when considering the introduction of new measures to manage migration movements.

  8. Asylum-seeking children's experiences of detention in Canada: A qualitative study.

    Kronick, Rachel; Rousseau, Cécile; Cleveland, Janet

    2015-05-01

    Children and parents seeking asylum are regularly detained in Canada, however little is known about the experiences of detained families. International literature suggests that the detention of children is associated with significant morbidity. Our study aims to understand the experiences of detained children and families who have sought asylum in Canada by using a qualitative methodology that includes semistructured interviews and ethnographic participant observation. Detention appears to be a frightening experience of deprivation that leaves children feeling criminalized and helpless. Family separation further shatters children's sense of well-being. Children's emotional and behavioral responses to separation and to detention suggest that the experience is acutely stressful and, in some cases, traumatic--even when detention is brief. Distress and impairment may persist months after release. Given the burden of psychological suffering and the harmful consequences of separating families, children should not be detained for immigration reasons and parents should not be detained without children.

  9. Making Sense of Pain: Delusions, Syphilis, and Somatic Pain in London County Council Asylums, c. 1900

    Full Text Available During the late nineteenth century, a high percentage of male deaths in asylums was attributed to various forms of tertiary syphilis, most notably General Paralysis of the Insane (GPI and tabes dorsalis. It was not unusual for patients to present symptoms of both conditions, the latter of which could be agonizingly painful. Some patients also suffered from persecutory delusions, believing that electricity was running through them or that their limbs were gnawed by lions and wolves at night. Drawing on a theory advanced by a number of key alienists and pathologists of the period, I suggest that these delusions were misinterpretations of felt sensations and, as such, illusions rather than delusions. Despite the well-known problems around using these historical sources, I contend that recorded delusions in asylum case notes can be treated as narratives of pain that provide invaluable insights into patients' subjective experiences.

    years ago. Within that record is a quasi-periodic rise and fall of about 160 ? 40 years in duration and a shorter fluctuation of 32 ? 6 years that is superimposed on the 160-year fluctuation. Recorded lake-level history from 1860 to the present falls within the longer-term pattern and appears to be a single 160-year quasi-periodic fluctuation. Independent investigations of past climate change in the basin over the long-term period of record confirm that most of these changes in lake level were responses to climatically driven changes in water balance, including lake-level highstands commonly associated with cooler climatic conditions and lows with warm climate periods. The mechanisms underlying these large hydroclimatic anomalies are not clear, but they may be related to internal dynamics of the ocean-atmosphere system or dynamical responses of the ocean-atmosphere system to variability in solar radiation or volcanic activity. The large capacities of the Great Lakes allow them to store great volumes of water. As calculated at chart datum, Lake Superior stores more water (2,900 mi3) than all the other lakes combined (2,539 mi3). Lake Michigan's storage is 1,180 mi3; Lake Huron's, 850 mi3; Lake Ontario's, 393 mi3; and Lake Erie's, 116 mi3. Seasonal lake-level changes alter storage by as much as 6 mi3 in Lake Superior and as little as 2.1 mi3 in Lake Erie. The extreme high and low lake levels measured in recorded lake-level history have altered storage by as much as 31 mi3 in Lake Michigan-Huron and as little as 9 mi3 in Lake Ontario. Diversions of water into and out of the lakes are very small compared to the total volume of water stored in the lakes. The water level of Lake Superior has been regulated since about 1914 and levels of Lake Ontario since about 1960. The range of Lake Superior water-level fluctuations and storage has not been altered greatly by regulation. However, fluctuations on Lake Ontario have been reduced from 6.6 ft preregulation

    Full Text Available Abstract Background Asylum procedures are known to be protracted, stretching to over ten years in many host countries. International research shows high levels of distress for asylum seekers. Little is known about actual psychiatric morbidity in this population, especially during the first few years postmigration. Methods The mental health status of two groups of asylum seekers was assessed: Group 1 (n = 43 had arrived in Switzerland 2.9 (SD 1.1 months prior to assessment, while Group 2 (n = 43 had arrived 15.5 (SD 3.2 months prior to assessment. Psychiatric disorders were diagnosed using the Mini International Neuropsychiatric Interview (MINI. Symptom severity of posttraumatic stress disorder (Posttraumatic Diagnostic Scale, anxiety (Hopkins Symptom Checklist, depression (Hopkins Symptom Checklist, and pain (Verbal Rating Scale were assessed using self-report questionnaires. Postmigratory factors such as German language proficiency and social contacts were also assessed. Interviews were conducted with the assistance of trained interpreters. Results Four out of ten participants met diagnostic criteria for at least one DSM-IV disorder. Groups did not differ with respect to psychiatric morbidity or symptom levels. Major depression (31.4% and PTSD (23.3% were diagnosed most frequently. The number of experienced traumatic event types was highly correlated with psychiatric morbidity. Conclusions Psychiatric morbidity in asylum seekers in the first two years after arrival is high, with no indication of a decrease in mental distress over time. Traumatic experiences seem to play a major role in morbidity during this time. Considering the magnitude of clinically relevant distress, a short psychological screening upon arrival with a focus on traumatic experiences may be warranted.

    2016-08-01

    European governments are struggling with the biggest refugee crisis since World War II, but there exists little evidence regarding how the management of the asylum process affects the subsequent integration of refugees in the host country. We provide new causal evidence about how one central policy parameter, the length of time that refugees wait in limbo for a decision on their asylum claim, affects their subsequent economic integration. Exploiting exogenous variation in wait times and registry panel data covering refugees who applied in Switzerland between 1994 and 2004, we find that one additional year of waiting reduces the subsequent employment rate by 4 to 5 percentage points, a 16 to 23% drop compared to the average rate. This deleterious effect is remarkably stable across different subgroups of refugees stratified by gender, origin, age at arrival, and assigned language region, a pattern consistent with the idea that waiting in limbo dampens refugee employment through psychological discouragement, rather than a skill atrophy mechanism. Overall, our results suggest that marginally reducing the asylum waiting period can help reduce public expenditures and unlock the economic potential of refugees by increasing employment among this vulnerable population.

    Background In the summer of 2015, the exodus of Syrian war refugees and saturation of refugee camps in neighbouring countries led to the influx of asylum-seekers in European countries, including Belgium. This study aims to describe the demographic and clinical characteristics of asylum seekers who arrived in a huddled refugee camp, in the centre of a well-developed country with all medical facilities. Methods Using a descriptive cross-sectional study design, physicians of Médecins du Monde prospectively registered age, gender, origin, medical symptoms and diagnoses of all patients presenting to an erected field hospital in Brussels in September 2015. Diagnoses were post hoc categorised according to the International Classification of Diseases. Results Of 4037 patients examined in the field hospital, 3907 were included and analysed for this study. Over 11% of patients suffered from injuries, but these were outnumbered by the proportion of patients with respiratory (36%), dental (9%), skin (9%) and digestive (8%) diagnoses. More than 49% had features of infections at the time of the consultation. Conclusions Asylum seekers arriving in a refugee camp in Brussels after a long and hazardous journey suffer mostly from respiratory, dental, skin and digestive diseases. Still, one in seven suffers from injury. These findings, consistent with other reports, should be anticipated when composing emergency medical teams and interagency emergency health or similar kits to be used in a field hospital, even in a Western European country.

    2013-09-01

    Current literature has indicated a concern about standards of maternity care experienced by pregnant women who are seeking asylum. As the next generation of midwives, it is important that students are educated in a way that prepares them to effectively care for these women. To understand how this can be achieved, it is important to explore what asylum seeking means to midwifery students. This article is the first of three parts and reports on one objective from a wider doctorate study. It identifies dominant discourses that influenced the perceptions of a group of midwifery students' about the pregnant asylum seeking woman. The study was designed from a social constructivist perspective, with contextual knowledge being constructed by groups of people, influenced by underpinning dominant discourses, depending on their social, cultural and historical positions in the world. In a United Kingdom University setting, during year two of a pre-registration midwifery programme, eleven midwifery students participated in the study. Two focus group interviews using a problem based learning scenario as a trigger for discussion were conducted. In addition, three students were individually interviewed to explore issues in more depth and two students' written reflections on practice were used to generate data. Following a critical discourse analysis, dominant discourses were identified which appeared to influence the way in which asylum seekers were perceived. The findings suggested an underpinning ideology around the asylum seeker being different and of a criminal persuasion. Although the pregnant woman seeking asylum was considered as deserving of care, the same discourses appeared to influence the way in which she was constructed. However, as the study progressed, through reading alternative sources of literature, some students appeared to question these discourses. These findings have implications for midwifery education in encouraging students to challenge negative discourses

    Full Text Available Abstract Background About 80% of new tuberculosis cases in Norway occur among immigrants from high incidence countries. On arrival to the country all asylum seekers are screened with Mantoux test and chest x-ray aimed to identify cases of active tuberculosis and, in the case of latent tuberculosis, to offer follow-up or prophylactic treatment. We assessed a national programme for screening, treatment and follow-up of tuberculosis infection and disease in a cohort of asylum seekers. Methods Asylum seekers ≥ 18 years who arrived at the National Reception Centre from January 2005 to June 2006, were included as the total cohort. Those with a Mantoux test ≥ 6 mm or positive x-ray findings were included in a study group for follow-up. Data were collected from public health authorities in the municipality to where the asylum seekers had moved, and from hospital based internists in case they had been referred to specialist care. Individual subjects included in the study group were matched with the Norwegian National Tuberculosis Register which receive reports of everybody diagnosed with active tuberculosis, or who had started treatment for latent tuberculosis. Results The total cohort included 4643 adult asylum seekers and 97.5% had a valid Mantoux test. At least one inclusion criterion was fulfilled by 2237 persons. By end 2007 municipal public health authorities had assessed 758 (34% of them. Altogether 328 persons had been seen by an internist. Of 314 individuals with positive x-rays, 194 (62% had seen an internist, while 86 of 568 with Mantoux ≥ 15, but negative x-rays (16% were also seen by an internist. By December 31st 2006, 23 patients were diagnosed with tuberculosis (prevalence 1028/100 000 and another 11 were treated for latent infection. Conclusion The coverage of screening was satisfactory, but fewer subjects than could have been expected from the national guidelines were followed up in the community and referred to an internist.

    2016-04-01

    Full Text Available Croatia’s accession to the EU has brought new challenges and issues in researching and analysing migration flows and trends as well as attitudes and perceptions of real and potential newcomers. The aim of this paper is to explore attitudes of the residents of the two most easterly Croatian counties towards two distinct categories of newcomers: immigrant workers and asylum seekers. The research was conducted shortly after Croatia’s entry into the EU, in September 2013, and the presented data are a part of a larger survey that included various migration and ethnicity issues. The survey was applied on a convenience sample of 1 110 adult respondents in two counties: Osijek-Baranja and Vukovar-Srijem. Data were analysed in a series of multivariate procedures. Results indicated significant perceptions of immigrant workers within the dimension of cultural threat, along with the expression of a considerable degree of social distance towards them. Asylum seekers were further perceived as a security and economic threat. Within two analysed regression models, the effects on attitudes towards immigrant workers and asylum seekers were similar. Among the spectrum of socio-demographic variables, a statistically significant effect on both dependent variables came from age and political orientation, indicating that older and politically right-oriented respondents expressed more negative attitudes towards both groups. Among other socio-demographic variables, education was significant in predicting attitudes towards immigrant workers, while ethnicity was significant in predicting the attitudes towards asylum seekers. The second model analysed the effect of selected political attitudes and value orientations resulting in significant prediction of negative attitudes towards both groups by pronounced conservativism, support of aggression and submission, social-dominance, dominant submissive authoritarianism and social alienation, rejecting socially oriented

  1. The Impact of Externalization of Migration Controls on the Rights of Asylum Seekers and Other Migrants

    Full Text Available Wars, conflict, and persecution have forced more people to flee their homes and seek refuge and safety elsewhere than at any time since the end of World War II. As displaced people and other migrants increasingly move out of the conflict-ridden and less developed regions of their displacement and into relatively rich and stable regions of the world, the countries of destination are increasingly working to contain and even stem the migration flow before it reaches their shores. Perversely, countries that have developed generally rights-sensitive standards and procedures for assessing protection claims of asylum seekers within their jurisdictions have simultaneously established barriers that prevent migrants, including asylum seekers, from setting foot on their territories or otherwise triggering protection obligations. Consequently, those who would otherwise have been able to avail themselves of asylum procedures, social support, and decent reception conditions are often relegated to countries of first arrival or transit that have comparatively less capacity to ensure protection of human rights in accordance with international standards.This paper seeks to develop a working definition of the externalization of migration controls and how such externalization of the border implicates the human rights of migrants, and asylum seekers in particular. Although the majority of those migrants seeking legal protections stay in countries neighboring their own, hundreds of thousands continue their journeys in search of protection and stability in more distant states, including in the European Union, the United States, and Australia. In response to the significant increase in asylum seekers arriving at their borders, all three entities have significantly increased deterrence measures with the hopes of keeping new arrivals from entering. This paper will thus highlight a number of the most troubling externalization strategies used by the European Union, the

    Full Text Available Abstract Background Several suicide and suicidal behaviour risk factors are highly prevalent in asylum seekers, but there is little insight into the suicide death rate and the suicidal behaviour incidence in this population. The main objective of this study is to assess the burden of suicide and hospital-treated non-fatal suicidal behaviour in asylum seekers in the Netherlands and to identify factors that could guide prevention. Methods We obtained data on cases of suicide and suicidal behaviour from all asylum seeker reception centres in the Netherlands (period 2002-2007, age 15+. The suicide death rates in this population and in subgroups by sex, age and region of origin were compared with the rate in the Dutch population; the rates of hospital-treated suicidal behaviour were compared with that in the population of The Hague using indirect age group standardization. Results The study included 35 suicide deaths and 290 cases of hospital-treated suicidal behaviour. The suicide death rate and the incidence of hospital-treated suicidal behaviour differed between subgroups by sex and region of origin. For male asylum seekers, the suicide death rate was higher than that of the Dutch population (N = 32; RR = 2.0, 95%CI 1.37-2.83. No difference was found between suicide mortality in female asylum seekers and in the female general population of the Netherlands (N = 3; RR = 0.73; 95%CI 0.15-2.07. The incidence of hospital-treated suicidal behaviour was high in comparison with the population of The Hague for males and females from Europe and the Middle East/South West Asia, and low for males and females from Africa. Health professionals knew about mental health problems prior to the suicidal behaviour for 80% of the hospital-treated suicidal behaviour cases in asylum seekers. Conclusions In this study the suicide death rate was higher in male asylum seekers than in males in the reference population. The incidence of hospital-treated suicidal behaviour

    Full Text Available Limnology is a border discipline between geography, hydrology and biology, and is also closely connected with other sciences, from it borrows research methods. Physical limnology (the geography of lakes, studies lake biotopes, and biological limnology (the biology of lakes, studies lake biocoenoses. The father of limnology is the Swiss scientist F.A. Forel, the author of a three-volume entitled Le Leman: monographie limnologique (1892-1904, which focuses on the geology physics, chemistry and biology of lakes. He was also author of the first textbook of limnology, Handbuch der Seenkunde: allgemeine Limnologie,(1901. Since both the lake biotope and its biohydrocoenosis make up a single whole, the lake and lakes, respectively, represent the most typical systems in nature. They could be called limnosystems (lacustrine ecosystems, a microcosm in itself, as the American biologist St.A. Forbes put it (1887.

  7. Emaciated, Exhausted and Excited: The Bodies and Minds of the Irish in Nineteenth-Century Lancashire Asylums.

    Cox, Catherine; Marland, Hilary; York, Sarah

    2012-01-01

    Drawing on asylum reception orders, casebooks and annual reports, as well as County Council notebooks recording the settlement of Irish patients, this article examines a deeply traumatic and enduring aspect of the Irish migration experience, the confinement of large numbers of Irish migrants in the Lancashire asylum system between the 1850s and the 1880s. This period saw a massive influx of impoverished Irish into the county, particularly in the post-Famine years. Asylum superintendents commented on the impact of Irish patients in terms of resulting management problems in what became, soon after their establishment, overcrowded and overstretched asylums. The article examines descriptions of Irish patients, many of whom were admitted in a poor state of health. They were also depicted as violent and difficult to manage, though reporting of this may have been swayed by anti-Irish sentiment. The article suggests that a hardening of attitudes took place in the 1870s and 1880s, when theories of degeneration took hold and the Irish in Ireland exhibited exceptionally high rates of institutionalization. It points to continuities across this period: the ongoing association between mental illness and migration long after the massive Famine influx had abated, and claims that the Irish, at one and the same time referred to as volatile and vulnerable, were particularly susceptible to the challenges of urban life, marked by their intemperance, liability to general paralysis, turbulence and immorality. Asylum superintendents also noted the relative isolation of the Irish, which led to their long-term incarceration. The article suggests that commentary about Irish asylum patients provides traction in considering broader perceptions of the Irish body, mobility and Irishness in nineteenth-century England, and a deeper understanding of institutionalization.

    Background QuantiFERON®TB Gold (QFT) is a promising blood test for tuberculosis infection but with few data so far from immigrant screening. The aim of this study was to compare results of QFT and tuberculin skin test (TST) among newly arrived asylum seekers in Norway and to assess the role of QFT in routine diagnostic screening for latent tuberculosis infection. Methods The 1000 asylum seekers (age ≥ 18 years) enrolled in the study were voluntarily recruited from 2813 consecutive asylum seekers arriving at the national reception centre from September 2005 to June 2006. Participation included a QFT test and a questionnaire in addition to the mandatory TST and chest X-ray. Results Among 912 asylum seekers with valid test results, 29% (264) had a positive QFT test whereas 50% (460) tested positive with TST (indurations ≥ 6 mm), indicating a high proportion of latent infection within this group. Among the TST positive participants 50% were QFT negative, whereas 7% of the TST negative participants were QFT positive. There was a significant association between increase in size of TST result and the likelihood of being QFT positive. Agreement between the tests was 71–79% depending on the chosen TST cut-off and it was higher for non-vaccinated individuals. Conclusion By using QFT in routine screening, further follow-up could be avoided in 43% of the asylum seekers who would have been referred if based only on a positive TST (≥ 6 mm). The proportion of individuals referred will be the same whether QFT replaces TST or is used as a supplement to confirm a positive TST, but the number tested will vary greatly. All three screening approaches would identify the same proportion (88–89%) of asylum seekers with a positive QFT and/or a TST ≥ 15 mm, but different groups will be missed. PMID:18479508

  9. Non-clinicians’ judgments about asylum seekers’ mental health: how do legal representatives of asylum seekers decide when to request medico-legal reports?

    2012-10-01

    Full Text Available Background : Procedures for determining refugee status across Europe are being speeded up, despite the high prevalence of mental health difficulties among asylum seekers. An assurance given is that ‘‘vulnerable applicants’’ will be identified and excluded from accelerated procedures. Although experts have recommended assessments to be undertaken by experienced clinicians, this is unlikely to happen for political and financial reasons. Understanding how non-clinically qualified personnel perform assessments of mental health issues is timely and crucial. Misrecognition of refugees due to the inappropriate use of accelerated procedures involves the risk of returning the very people who have the right to protection from further persecution. Objective : To examine the decision making of immigration lawyers, who are an example of a group of nonclinicians who decide when and whether to refer asylum-seekers for psychiatric assessment. Method : Semi-structured interviews were conducted with 12 legal representatives working with people seeking refugee or human rights protection in the United Kingdom. The resultant material was analysed using Framework Analysis. Results : Themes clustered around the legal case, the client, the representative and the systems, all with sub-themes. A mapping exercise integrated these themes to show how representatives brought together questions of (1 evidential reasons for a report, influenced by their legal, psychological and case law knowledge, and (2 perceived evidence of mental distress, influenced by professional and personal experiences and expectations. Conclusions : The legal representatives interviewed were well-informed and trained in psychological issues as well as clearly dedicated to their clients. This helped them to attempt quasi-diagnoses of common mental health problems. They nonetheless demonstrated stereotypical understanding of post-traumatic stress disorder and other possible diagnoses and the

    Full Text Available This paper examines the rise of an asylum seeker and refugee advocacy movement in Australia in recent years. It situates this phenomenon within Alberto Melucci's understanding of social movements as variable and diffuse forms of social action involved in challenging the logic of a system. Following this theoretical framework, it explores the empirical features of this particular collective action, as well as the struggle to redefine the nature of the relationship between citizens of a sovereign state and 'the other' in the personage of asylum seekers and refugees.

  11. What do language barriers cost? An exploratory study among asylum seekers in Switzerland

    Full Text Available Abstract Background Language barriers have a major impact on both the quality and the costs of health care. While there is a growing body of evidence demonstrating the detrimental effects of language barriers on the quality of health care provision, less is known about their impact on costs. This purpose of this study was to investigate the association between language barriers and the costs of health care. Methods The data source was a representative set of asylum seekers whose health care was provided by a Swiss Health Maintenance Organisation (HMO. A cross-sectional survey was conducted: data was collected on all the asylum seekers' health care costs including consultations, diagnostic examinations, medical interventions, stays in the clinic, medication, and interpreter services. The data were analysed using path analysis. Results Asylum seekers showed higher health care costs if there were language barriers between them and the health professionals. Most of these increased costs were attributable to those patients who received interpreter services: they used more health care services and more material. However, these patients also had a lower number of visits to the HMO than patients who faced language barriers but did not receive interpreter services. Conclusion Language barriers impact health care costs. In line with the limited literature, the results of this study seem to show that interpreter services lead to more targeted health care, concentrating higher health care utilisation into a smaller number of visits. Although the initial costs are higher, it can be posited that the use of interpreter services prevents the escalation of long-term costs. A future study specially designed to examine this presumption is needed.

  12. School and community-based interventions for refugee and asylum seeking children: a systematic review.

    Rebecca A Tyrer

    Full Text Available Research for effective psychological interventions for refugee and asylum-seeking children has intensified. The need for interventions in environments more easily accessed by children and families is especially relevant for newly arrived populations. This paper reviews the literature on school and community-based interventions aimed at reducing psychological disorders in refugee and asylum-seeking children.Comprehensive searches were conducted in seven databases and further information was obtained through searching reference lists, grey literature, and contacting experts in the field. Studies were included if they reported on the efficacy of a school or community-based mental health intervention for refugee or asylum-seeking children. Two independent reviewers made the final study selection, extracted data, and reached consensus on study quality. Results were summarized descriptively. The marked heterogeneity of studies excluded conducting a meta-analysis but study effect-sizes were calculated where possible. Twenty one studies met inclusion criteria for the review reporting on interventions for approximately 1800 refugee children. Fourteen studies were carried out in high-income countries in either a school (n = 11 or community (n = 3 setting and seven studies were carried out in refugee camps. Interventions were either primarily focused on the verbal processing of past experiences (n = 9, or on an array of creative art techniques (n = 7 and others used a combination of these interventions (n = 5. While both intervention types reported significant changes in symptomatology, effect sizes ranged from 0.31 to 0.93 and could mainly be calculated for interventions focusing on the verbal processing of past experiences.Only a small number of studies fulfilled inclusion criteria and the majority of these were in the school setting. The findings suggest that interventions delivered within the school setting can be successful in

    Full Text Available Abstract Background There has been much debate regarding the refugee health situation in the UK. However most of the existing literature fails to take account of the opinions of refugees themselves. This study was established to determine the views of asylum seekers and refugees on their overall experiences in primary care and to suggest improvements to their care. Methods Qualitative study of adult asylum seekers and refugees who had entered the UK in the last 10 years. The study was set in Barnet Refugee Walk in Service, London. 11 Semi structured interviews were conducted and analysed using framework analysis. Results Access to GPs may be more difficult for failed asylum seekers and those without support from refugee agencies or family. There may be concerns amongst some in the refugee community regarding the access to and confidentiality of professional interpreters. Most participants stated their preference for GPs who offered advice rather than prescriptions. The stigma associated with refugee status in the UK may have led to some refugees altering their help seeking behaviour. Conclusion The problem of poor access for those with inadequate support may be improved by better education and support for GPs in how to provide for refugees. Primary Care Trusts could also supply information to newly arrived refugees on how to access services. GPs should be aware that, in some situations, professional interpreters may not always be desired and that instead, it may be advisable to reach a consensus as to who should be used as an interpreter. A better doctor-patient experience resulting from improvements in access and communication may help to reduce the stigma associated with refugee status and lead to more appropriate help seeking behaviour. Given the small nature of our investigation, larger studies need to be conducted to confirm and to quantify these results.

    The levels of exposure to conflict-related trauma and the high rates of mental health impairment amongst asylum seekers pose specific challenges for refugee decision makers who lack mental health training. We examined the use of psychological evidence amongst asylum decision makers in New South Wales, Australia, drawing on the archives of a representative cohort of 52 asylum seekers. A mixed-method approach was used to examine key mental health issues presented in psychological reports accompanying each asylum application, including key documents submitted for consideration of asylum at the primary and review levels. The findings indicated that the majority of decision makers at both levels did not refer to psychological evidence in their decision records. Those who did, particularly in the context of negative decisions, challenged the expert findings and rejected the value of such evidence. Asylum seekers exhibiting traumatic stress symptoms such as intrusive thoughts and avoidance, as well as memory impairment, experienced a lower acceptance rate than those who did not across the primary and review levels. The findings raise concern that trauma-affected asylum seekers may be consistently disadvantaged in the refugee decision-making process and underscore the need to improve the understanding and use of mental health evidence in the refugee decision-making setting. The study findings have been used to develop a set of guidelines to assist refugee decision makers, mental health professionals and legal advisers in improving the quality and use of psychological evidence within the refugee decision-making context.

    The impact of industrialised host nations' deterrent immigration policies on the mental health of forced migrants has not been well characterised. The present study investigated the impact of Australia's refugee determination process (RDP) on psychiatric morbidity in community-based asylum-seekers (AS) and refugees. Psychiatric morbidity was predicted to be greater in AS than refugees, and to persist or increase as a function of time in the RDP. The effect on mental health of demographic and socio-political factors such as health cover and work rights were also investigated. Psychiatric morbidity was measured prospectively on five mental health indices at baseline (T1, n=131) and an average of 15.7 months later (T2, n=56). Psychiatric morbidity in AS significantly decreased between time points such that it was no longer greater than that of refugees at T2. Caseness of PTSD and demoralisation reduced in AS who gained protection; however, those who maintained asylum-seeker status at T2 also had a significant reduction in PTS and depression symptom severity. Reduced PTS and demoralisation symptoms were associated with securing work rights and health cover. Living in the community with work rights and access to health cover significantly improves psychiatric symptoms in forced migrants irrespective of their protection status.

    2014-05-01

    Full Text Available Southern European countries have come to constitute the most vulnerable external border of the European Union (EU over the last decade. Irregular migration pressures have been acutely felt on the EU’s southern sea borders, and particularly on four sets of islands: Canary Islands (Spain, Lampedusa and Linosa (Italy, Malta, and Aegean Islands (Greece. This quartet is, to a large extent, used as stepping stones by irregular migrants and asylum seekers to reach the European continent. This paper studies the role of these islands as ‘outposts’ of a framework of externalization. It starts by discussing the notion of externalization and its different facets. It considers how externalization is linked to both fencing and gate-keeping strategies of migration and asylum control. The second part of the paper focuses on the special role of the island quartet with respect to the externalization web cast by national and EU-wide migration policies. It concludes with a critical reflection on the multi-level character of externalization policies and practices that occur both within the EU and between the EU and third countries.

  20. Sleeping patterns of Afghan unaccompanied asylum-seeking adolescents: a large observational study.

    Directory of Open Access Journals (Sweden)

    Israel Bronstein

    Full Text Available Unaccompanied asylum-seeking children (UASC have experienced multiple traumas and are a high-risk group for posttraumatic stress disorder (PTSD. The effects of trauma are known to be associated with sleep problems; indeed sleeping problems are core features of PTSD. However, there has been no systematic research examining the sleep of this high risk group of children. This study presents the first evidence on the sleeping patterns of Afghan UASC living in the UK. A total of 222 male Afghan children, aged 13-18, were interviewed using validated self-report questionnaires measuring sleeping patterns and PTSD. Overall, UASC patterns for bed time and rise time appear acculturated to the country of asylum. Mean UASC sleep onset latency scores were approximately 20 minutes greater compared with normative scores, which may be a reflection of UASC pre-migration and post-migration experiences. As expected, UASC who screened above the clinical cut-off for PTSD reported significantly greater sleep onset latency, increased nightmares, and less total sleep time compared to the non-PTSD group. The results may be of particular interest to clinicians given that, compared to screening for PTSD, screening for sleep problems may be a less culturally disputed form of initial assessment indicating distress in UASC. Similarly, the field of UASC and refugee child interventions is largely focused on trauma, yet sleep may provide a novel avenue for equally or more effective treatment.

    Full Text Available Background: Current knowledge is limited regarding patient characteristics related to treatment outcome of posttraumatic stress disorders (PTSD in refugees and asylum seekers. Objective: Gender, torture status, offender status, level of anger, and level of depression were investigated for possible effects on the treatment outcome. Method: Patient characteristics were explored in 54 refugees and asylum seekers who had completed a treatment program for PTSD. Non-responders (10, those who had the same or higher levels of symptom severity after treatment, were compared with responders, those who had lower symptom severity after treatment (44. Symptom severity was measured by Clinician-Administered PTSD Scale. The non-responders and responders constituted the dichotomous, dependent variable. The independent variables were gender, torture status, offender status, level of anger, and level of depression. T-tests and Exact Unconditional Homogeneity/Independence Tests for 2X2 Tables were used to study the relationship to treatment outcome. Results: Being male and reporting to have been a violent offender were significantly more frequent characteristics among the non-responders compared to the responders. The levels of pretreatment anger, depression and torture status did not affect the treatment outcome. Conclusions: The study adds support to findings that females benefit more from treatment of PTSD than males and that violent offenders are difficult to treat within the standard treatment programs.

    2014-04-01

    Recent scholarship has explored the dynamics between families and colonial lunatic asylums in the late nineteenth century, where families actively participated in the processes of custodial care, committal, treatment and release of their relatives. This paper works in this historical field, but with some methodological and theoretical differences. The Foucauldian study is anchored to a single case and family as an illness narrative that moves cross-referentially between bureaucratic state archival material, psychiatric case records, and intergenerational family-storytelling and family photographs. Following headaches and seizures, Harry Walter Wilbraham was medically boarded from his position as Postmaster in the Cape of Good Hope Colony of South Africa with a 'permanent disease of the brain', and was committed to the Grahamstown Asylum in 1910, where he died the following year, aged 40 years. In contrast to writings about colonial asylums that usually describe several patient cases and thematic patterns in archival material over time and place, this study's genealogical lens examines one white settler male patient's experiences within mental health care in South Africa between 1908 and 1911. The construction of Harry's 'case' interweaves archival sources and reminiscences inside and outside the asylum, and places it within psychiatric discourse of the time, and family dynamics in the years that followed. Thus, this case study maps the constitution of 'patient' and 'family' in colonial life, c.1888-1918, and considers the calamity, uncertainty, stigma and silences of mental illness.

    Interest in the integration of refugees has grown with the increase in numbers of asylum seekers dispersed across the UK. The ability to communicate effectively in English is seen as the key priority in facilitating integration, while a lack of English language is seen as one of the major barriers to refugee employment. Some 267 million British…

    Past research has documented the role acculturation plays in the process of adjustment to new cultures among migrants. Yet little attention has been paid thus far to the role of acculturation in the context of forced migration. In this study we examined the association between acculturation patterns and mental health symptoms among a convenience sample of Eritrean and Sudanese asylum seekers (n = 118) who accessed health services at the Physicians for Human Rights Open-Clinic in Israel. Participants completed measures on sociodemographic information as well as detention history, mental health symptoms, exposure to traumatic events, and acculturation pattern, in their native language upon accessing services. Consistent with our predictions, findings showed that acculturation predicted depressive symptoms among asylum seekers beyond the effect of history of detention and reports of experiences of traumatic events. Assimilated compared with integrated asylum seekers reported higher depressive symptoms. Findings draw attention to the paradox of assimilation, and the mental health risks it poses among those wishing to integrate into the new culture at the expanse of their original culture. Asylum seekers may be particularly vulnerable to the risks of assimilation in the restrictive policies that characterize many industrial countries in recent years.

    2012-04-01

    The period 1820-60 marked an era of transition and diversity in Ireland that rapidly transformed the face of Irish society. Inextricably linked with these processes was the expansion of Ireland's private asylum system. This system diverged from its British counterpart both in the socioeconomic cohort it served and in the role it played within the mental health-care system as a whole. The implementation of the 1842 Private Asylums (Ireland) Act, the first legislative measure geared exclusively toward the system, highlighted the growing importance of private care in Ireland as well as providing for the licensing and regulation of these institutions for the first time. To date, historians of Irish medicine have focused almost exclusively on the pauper insane. This article aims to shift this emphasis toward other categories of the Irish insane through exploration of the Irish private asylum system, its growth throughout the period, and the social profile of private patients. I shall also interrogate the trade in lunacy model through exploration of financial considerations, discharge and recovery rates, and conditions of care and argue that while Irish private institutions were a lucrative business venture, the quality of care upheld was apparently high. Finally, I shall argue that Irish private asylums catered primarily for the upper classes and briefly explore alternative provisional measures for other non-pauper sectors of society.

    Information on miRNA targeting genes is growing rapidly. For high-throughput experiments, but also for targeted analyses of few genes or miRNAs, easy analysis with concise representation of results facilitates the work of life scientists. We developed miRTargetLink, a tool for automating respective analysis procedures that are frequently applied. Input of the web-based solution is either a single gene or single miRNA, but also sets of genes or miRNAs, can be entered. Validated and predicted targets are extracted from databases and an interaction network is presented. Users can select whether predicted targets, experimentally validated targets with strong or weak evidence, or combinations of those are considered. Central genes or miRNAs are highlighted and users can navigate through the network interactively. To discover the most relevant biochemical processes influenced by the target network, gene set analysis and miRNA set analysis are integrated. As a showcase for miRTargetLink, we analyze targets of five cardiac miRNAs. miRTargetLink is freely available without restrictions at www.ccb.uni-saarland.de/mirtargetlink.

    Full Text Available Abstract Background Hypovitaminosis D is well known in different populations, but may be under diagnosed in certain populations. We aim to determine the first diagnosis considered, the duration and resolution of symptoms, and the predictors of response to treatment in female asylum seekers suffering from hypovitaminosis D. Methods Design: A pre- and post-intervention observational study. Setting: A network comprising an academic primary care centre and nurse practitioners. Participants: Consecutive records of 33 female asylum seekers with complaints compatible with osteomalacia and with hypovitaminosis D (serum 25-(OH vitamin D Treatment intervention: The patients received either two doses of 300,000 IU intramuscular cholecalciferol as well as 800 IU of cholecalciferol with 1000 mg of calcium orally, or the oral treatment only. Main outcome measures: We recorded the first diagnosis made by the physicians before the correct diagnosis of hypovitaminosis D, the duration of symptoms before diagnosis, the responders and non-responders to treatment, the duration of symptoms after treatment, and the number of medical visits and analgesic drugs prescribed 6 months before and 6 months after diagnosis. Tests: Two-sample t-tests, chi-squared tests, and logistic regression analyses were performed. Analyses were performed using SPSS 10.0. Results Prior to the discovery of hypovitaminosis D, diagnoses related to somatisation were evoked in 30 patients (90.9%. The mean duration of symptoms before diagnosis was 2.53 years (SD 3.20. Twenty-two patients (66.7% responded completely to treatment; the remaining patients were considered to be non-responders. After treatment was initiated, the responders' symptoms disappeared completely after 2.84 months. The mean number of emergency medical visits fell from 0.88 (SD 1.08 six months before diagnosis to 0.39 (SD 0.83 after (P = 0.027.

    Lead isotope ratios and lead (Pb) levels were analyzed in 33 individuals from a forgotten cemetery at the Colorado Mental Health Institute at Pueblo, Colorado dating to 1879-1899. Isotopic ratios from healing bone fractures, cortical bone, and tooth dentine provide information about sources of Pb exposures over a range of time that illuminates individual's life histories and migration patterns. Historical records and Pb production data from the 19th century were used to create a database for interpreting Pb exposures for these African, Hispanic and European Americans. The analysis of these individuals suggests that Pb exposure noticeably impacted the mental health of 5-10% of the asylum patients in this frontier population, a high number by standards today, and that differences exist in the three ancestral groups' exposure histories.

  9. Representation of Refugees, Asylum-Seekers and Refugee Affairs In Hungarian Dailies

    Lilla VICSEK

    2008-11-01

    Full Text Available How does the press in Hungary write about refugees, asylum-seekers and refugee affairs? We sought to answer this question. Articles appearing in 2005 and 2006 in two leading national Hungarian dailies were examined with quantitative content analysis. The results show that the articles analyzed often treat refugee affairs as an “official” political matter. The high proportion of legislation and political positions conveys the image that refugee affairs are a state or intergovernmental matter, an “official”, legal, political issue rather than for example a humanitarian question. Most of the articles published in both papers write about problems and conflicts in connection with refugee affairs. The negative media image has different significance for different topics. We argue that the question of refugee affairs is a topic where the image shown by the media is of great relevance: the media can be a more important source of information on this subject than personal contacts.

    Full Text Available This photographic essay presents images from the City of London Asylum archive as a example of how the visual can be used to expand our investigations of social histories of Victorian London, particularly the multi-cultural nature of the city. The essay argues that images are an essential part of the research process, but also discusses some of the disadvantages and ethical tensions encountered through the use of such portraits for historical recovery. Despite these caveats, the paper concludes that we have much to learn from the images that present images of the city that would otherwise be difficult, if not impossible, for twenty-first-century researchers to access.

    Full Text Available Forced displacement related to persecution and violent conflict has reached a new peak in recent years. The primary aim of this study is to provide an initial overview of the acute and chronic health care problems of asylum seekers from the Middle East, with special emphasis on asylum seekers from Syria.Our retrospective data analysis comprised adult patients presenting to our emergency department between 01.11.2011 and 30.06.2014 with the official resident status of an "asylum seeker" or "refugee" from the Middle East.In total, 880 patients were included in the study. Of these, 625 (71.0% were male and 255 (29.0% female. The median age was 34 (range 16-84. 222 (25.2% of our patients were from Syria. The most common reason for presentation was surgical (381, 43.3%, followed by medical (321, 36.5% and psychiatric (137, 15.6%. In patients with surgical presentations, trauma-related problems were most common (n = 196, 50.6%. Within the group of patients with medical presentation, acute infectious diseases were most common (n = 141, 43.9%, followed by neurological problems (n = 70, 21.8% and gastrointestinal problems (n = 47, 14.6%. There were no differences between Syrian and non-Syrian refugees concerning surgical or medical admissions. The most common chronic disorder of unclear significance was chronic gastrointestinal problems (n = 132, 15%, followed by chronic musculoskeletal problems (n = 108, 12.3% and chronic headaches (n = 78, 8.9%. Patients from Syria were significantly younger and more often suffered from a post-traumatic stress disorder than patients of other nationalities (p<0.0001, and p = 0.05, respectively.Overall a remarkable number of our very young group of patients suffered from psychiatric disorders and unspecified somatic symptoms. Asylum seekers should be carefully evaluated when presenting to a medical facility and physicians should be aware of the high incidence of unspecified somatic symptoms in this patient population

    In the populations of refugees and asylum seekers hosted in high-income countries, access to mental health care and psychotropic drugs, is a major challenge. A recent Swedish cross-sectional register study has explored this phenomenon in a national cohort of 43 403 young refugees and their families from Iraq, Iran, Eritrea, Ethiopia, Somalia and Afghanistan. This register study found lower rates of dispensed psychotropic drugs among recently settled refugees, as compared with Swedish-born residents, with an increase in the use with duration of residence. In this commentary, the results of this survey are discussed in view of their global policy implications for high-income countries hosting populations of refugees and asylum seekers.

    BACKGROUND: Refugees and asylum seekers experience language barriers in general practice. Qualitative studies have found that responses to language barriers in general practice are ad hoc with use of both professional interpreters and informal interpreters (patients\\' relatives or friends). However, the scale of the issues involved is unknown. This study quantifies the need for language assistance in general practice consultations and examines the experience of, and satisfaction with, methods of language assistance utilized. METHODS: Data were collected by telephone survey with general practitioners in a regional health authority in Ireland between July-August 2004. Each respondent was asked a series of questions about consulting with refugees and asylum seekers, the need for language assistance and the kind of language assistance used. RESULTS: There was a 70% (n = 56\\/80) response rate to the telephone survey. The majority of respondents (77%) said that they had experienced consultations with refugees and asylum seekers in which language assistance was required. Despite this, general practitioners in the majority of cases managed without an interpreter or used informal methods of interpretation. In fact, when given a choice general practitioners would more often choose informal over professional methods of interpretation despite the fact that confidentiality was a significant concern. CONCLUSION: The need for language assistance in consultations with refugees and asylum seekers in Irish general practice is high. General practitioners rely on informal responses. It is necessary to improve knowledge about the organisational contexts that shape general practitioners responses. We also recommend dialogue between general practitioners, patients and interpreters about the relative merits of informal and professional methods of interpretation so that general practitioners\\' choices are responsive to the needs of patients with limited English.

    Since 2004, a profound transformation of the asylum care model, characterized by overcrowding, lack of discharge and absence of rehabilitation programs, and social reinsertion, has been developed at National Colony "Dr. Manuel A. Montes de Oca". During this period, a plan that contemplates several programs and projects aimed at restoring the rights of institutionalized people with mental disabilities and promoting opportunities for social inclusion has been implemented.

  2. Turning Asylum Seekers into ‘Dangerous Criminals’: Experiences of the Criminal Justice System of those Seeking Sanctuary

    2015-10-01

    Full Text Available Since the events of 9/11 in the US in 2001 and, four years later, the 7/7 London bombings in the UK, warnings of terrorist attacks are high on the public agenda in many western countries. Politicians and tabloid press in the UK have continued to make direct and indirect connections between asylum seekers, terrorism and crime. This has increasingly resulted in harsh policy responses to restrict the movement of ‘third-world’ nationals, criminalisation of immigration and asylum policy, and making the violation of immigration laws punishable through criminal courts. This paper largely highlights the narratives of five asylum seekers who committed ‘crime’ by breaching immigration laws and were consequently treated as ‘dangerous criminals’ by the state authorities. More importantly it shows how these individuals experienced this treatment. The aim of this paper is to give voice to the victims of state abuse, claim space for victim agency, gather victim testimonies, challenge official explanations and in the process confront criminal and racist state practices.

    Full Text Available Object of this article is the destiny of psychiatric inmates in Wuerttemberg asylums, 1940-1945. These patients from Italian regions of Vicenza, Udine, Trento, Alto Adige and various locations more were delegated and, to a substantial number, illegally deported to the German asylums Zwiefalten, Schussenried and Weissenau, all in South Wuerttemberg, in 1940 and 1943. Attention is focused on the pioneering state pre-negotiations, and the so-called option treaties between the German Reich and Fascist Italy as part of the general aspect of National Socialist bio-Politics. The treatment of these South Tyrol patients in the asylums themselves, as well as their fate will be put into the context of the resettlement actions at the margins of the Third Reich, which started in 1939 and widely affected the European continent. It is referred to other sub-groups of migrating population from Italy to the German Reich as well, as a contrasting aspect of this contribution

Methods/Design The study will include random samples of adult asylum seekers and refugees from Afghanistan, Iran and Somali (total planned sample of 600, as these are among the largest groups within the reception centres and municipalities in the Netherlands. The questionnaire that will be used will include questions on physical health (chronic and acute diseases and somatization, mental health (Hopkins Symptoms Checklist-25 and Harvard Trauma Questionnaire, utilisation of health care services, pre- and post-migratory traumatic experiences, life-style, acculturation, social support and socio-demographic background. The questionnaire has gone through a translation process (translation and back-translation, several checks and a pilot-study and cross-cultural adaptation. Respondents will be interviewed by bilingual and bicultural interviewers who will be specifically trained for this purpose. This article discusses the selection of the study population, the chosen outcome measures, the translation and cross-cultural adaptation of the measurement instrument, the training of the interviewers and the practical execution of the study. The information provided may be useful for other researchers in this relatively new field of epidemiological research among various groups of asylum seekers and refugees.

  5. 'No "Sane" Person Would Have Any Idea': Patients' Involvement in Late Nineteenth-century British Asylum Psychiatry.

    2016-01-01

    In his 1895 textbook, Mental Physiology, Bethlem Royal Hospital physician Theo Hyslop acknowledged the assistance of three fellow hospital residents. One was a junior colleague. The other two were both patients: Walter Abraham Haigh and Henry Francis Harding. Haigh was also thanked in former superintendent George Savage's book Insanity and Allied Neuroses (1884). In neither instance were the patients identified as such. This begs the question: what role did Haigh and Harding play in asylum theory and practice? And how did these two men interpret their experiences, both within and outside the asylum? By focusing on Haigh and Harding's unusual status, this paper argues that the notion of nineteenth-century 'asylum patient' needs to be investigated by paying close attention to specific national and institutional circumstances. Exploring Haigh and Harding's active engagement with their physicians provides insight into this lesser-known aspect of psychiatry's history. Their experience suggests that, in some instances, representations of madness at that period were the product of a two-way process of negotiation between alienist and patient. Patients, in other words, were not always mere victims of 'psychiatric power'; they participated in the construction and circulation of medical notions by serving as active intermediaries between medical and lay perceptions of madness.

    Full Text Available William W BostockSchool of Government, University of Tasmania, Hobart, Tasmania, AustraliaAbstract: Psychiatrists have long had involvement with the political process, both individually and as a profession. They have made valuable contributions to debate over such issues as war, conflict, terrorism, torture, human rights abuse, drug abuse, suicide and other public health issues. However, they have also been complicit in some gross atrocities. Over several years there has been debate over the Australian Government’s treatment of asylum seekers, and the Royal Australian and New Zealand College of Psychiatrists took the unusual step of publicly criticizing the Australian Government’s policy on grounds of its toxicity leading to a diagnosis of collective depression syndrome, particularly among child detainees, but also adult detainees. The official Ministerial response was to deny that collective depression exists and to assert that the concept is meaningless. Can this intervention by psychiatrists be interpreted as a product of earlier political behaviors by psychiatrists? The willingness of psychiatrists to cooperate with other professions, notably psychologists, pediatricians, physicians and lawyers, is noted, as is presence of minority voices within the Australian psychiatric profession. The significance of the debate over the mental condition of asylum-seeking detainees is that its outcome has implications for how Australia sees itself and is seen by the rest of the world, that is, its national identity.Keywords: collective depression syndrome, psychiatric profession, political intervention, asylum seeker, Australian national identity

    MicroRNAs (miRNAs) regulate gene expression in a variety of biological pathways such as development and tumourigenesis. miRNAs are initially expressed as long primary transcripts (pri-miRNAs) that undergo sequential processing by Drosha and then Dicer to yield mature miRNAs. miR-17~92 is a miRNA cluster that encodes 6 miRNAs and while it is essential for development it also has reported oncogenic activity. To date, the role of RNA structure in miRNA biogenesis has only been considered in terms of the secondary structural elements required for processing of pri-miRNAs by Drosha. Here we report that the miR-17~92 cluster has a compact globular tertiary structure where miRNAs internalized within the core of the folded structure are processed less efficiently than miRNAs on the surface of the structure. Increased miR-92 expression resulting from disruption of the compact miR-17~92 structure results in increased repression of integrin α5 mRNA, a known target of miR-92a. In summary, we describe the first example of pri-miRNA structure modulating differential expression of constituent miRNAs.

A teoria dos movimentos sociais é aqui considerada como importante chave analítica para se compreender esta ação coletiva, na medida em que possibilita a avaliação deste tipo de ação social a partir de suas múltiplas configurações, atestando o grau de complexidade do mundo contemporâneo. O movimento antimanicomial constitui-se como um conjunto (plural de atores, cujas lutas e conflitos vêm sendo travadas a partir de diferentes dimensões sócio-político-institucionais. Trata-se de um movimento que articula, em diferentes momentos e graus, relações de solidariedade, conflito e de denúncias sociais tendo em vista as transformações das relações e concepções pautadas na discriminação e no controle do "louco" e da "loucura" em nosso país.This study reviews the history of the national anti-asylum struggle in Brazil. It analyzes some of the movement's difficulties, achievements and challenges. The theory of social movements is used here as an important analytical tool to understand this collective action, to the degree in which theory allows an appraisal of this type of social action rooted in its many configurations, evidencing the complexity of the contemporary world. The anti-asylum movement is composed of many stakeholders whose struggles and conflicts have been developed through different social-political-institutional dimensions. It encompasses at different moments and to different degrees, a movement which articulates solidarity and conflict relations and social denunciations in an attempt to transform relations and conceptions that are discriminatory and which are intended to control the "insane" and "insanity" in our country.

    Full Text Available The number of asylum seekers arriving in Germany has increased rapidly since 2014 and cases of vaccine-preventable diseases at reception centres were reported. Asylum seekers 12 years and older arriving in Lower Saxony were serologically screened for antibodies against measles, rubella and varicella between November 2014 and October 2015. We calculated the seroprevalence from the screening data by disease, country of origin and age group and compared them to literature-based herd immunity thresholds in order to identify immunisation gaps. In total, 23,647 specimens were included in our study. Although the vast majority of asylum seekers tested positive for antibodies against measles, rubella and varicella, the seroprevalences were not sufficient to ensure herd immunity. The seroprevalences varied substantially between countries of origin and increased with age. Immunisation of asylum seekers against measles, rubella and varicella is needed and the detailed information on seroprevalences among subgroups of asylum seekers can be used for targeted immunisations at reception centres.

Diet and lifestyle factors have been hypothesized to be involved in the regulation of miRNA expression. In this study it was hypothesized that diet and lifestyle factors are associated with miRNA expression. Data from 1,447 cases of colorectal cancer to evaluate 34 diet and lifestyle variables using miRNA expression in normal colorectal mucosa as well as for differential expression between paired carcinoma and normal tissue were used. miRNA data were obtained using an Agilent platform. Multiple comparisons were adjusted for using the false discovery rate q-value. There were 250 miRNAs differentially expressed between carcinoma and normal colonic tissue by level of carbohydrate intake and 198 miRNAs differentially expressed by the level of sucrose intake. Of these miRNAs, 166 miRNAs were differentially expressed for both carbohydrate intake and sucrose intake. Ninety-nine miRNAs were differentially expressed by the level of whole grain intake in normal colonic mucosa. Level of oxidative balance score was associated with 137 differentially expressed miRNAs between carcinoma and paired normal rectal mucosa. Additionally, 135 miRNAs were differentially expressed in colon tissue based on recent NSAID use. Other dietary factors, body mass index, waist and hip circumference, and long-term physical activity levels did not alter miRNA expression after adjustment for multiple comparisons. These results suggest that diet and lifestyle factors regulate miRNA level. They provide additional support for the influence of carbohydrate, sucrose, whole grains, NSAIDs, and oxidative balance score on colorectal cancer risk

  14. Toxaphene in Great Lakes biota and air

    Glassmeyer, Susan Theresa

    1998-11-01

    Toxaphene is a complex mixture of at least 600 hexa- through decachlorinated bornanes and bornenes, which was used as an insecticide in the United States from the 1950's until 1982, when it was banned. Toxaphene is ubiquitous in the environment, probably because of its atmospheric transport away from areas of use. Toxaphene's complex nature makes accurate quantitation difficult. I have developed a computer program to automate quantitation, thus decreasing the time required for analysis while maintaining precise quantitation. I have shown that toxaphene in lake trout (Salvelinus namaycush) and rainbow smelt (Osmerus mordax) taken from Lake Superior have not decreased as they have in the four other Great Lakes from the time of the ban though 1992. This result could be due to three possibilities: ( a) There had been a food chain perturbation that made the 1982 concentrations unusually low. (b) The physical properties of Lake Superior make the loss rate significantly lower than the other Great Lakes. (c) There are current sources of toxaphene entering the Lake Superior basin. I analyzed an extended time series of lake trout from Lake Superior and from northern Lake Michigan to test the first two hypotheses. The concentrations of toxaphene have been constant in trout from Lake Superior since the late 1970's, so hypothesis a can be negated. The northern Lake Michigan samples did not decline as greatly as the southern basin samples, so hypothesis b can not be disproved. To determine the atmospheric deposition of toxaphene to Lake Superior, I analyzed air samples collected every twelve days for sixteen months at Eagle Harbor, Michigan. The concentrations of toxaphene in these samples are similar to those found in recent studies of air collected at Traverse City, MI., but significantly lower than samples taken at a land based site in southern Ontario in 1988 and 1989. This difference in concentration may (or may not) be due to differences in sampling times or locations or

    Sociologist Erving Goffman based his seminal work Asylums (1961) on a year of field research at St. Elizabeths Hospital in Washington, DC. Goffman described the mental hospital as a "total institution," in which regimentation dominated every aspect of daily life and patients were denied even the most basic means of self-expression; rather than promote recovery, such conditions produced the sorts of disordered behavior for which men and women were ostensibly admitted. A closer look at the changes transforming St. Elizabeths around the time of Goffman's research reveals a far richer portrait of institutional culture. Group therapy, psychodrama, art and dance therapy, patient newspapers, and patient self-government-each of which debuted at the hospital in the 1940s and 1950s-provided novel opportunities for men and women to make themselves heard and to take their fate into their own hands. While these initiatives did not reach all of the patients at St. Elizabeths, surviving documentation suggests that those who participated found their involvement rewarding and empowering. Goffman explicitly set out to describe "the social world of the hospital inmate." His failure to appreciate fully the capacities of his subjects, however, appears to have led him to underestimate the importance of these developments.

    There is a lack of knowledge about psychosocial resources that may sustain post-resettlement psychological adjustment among unaccompanied minor asylum-seekers. The aim of this study is to investigate the impact of social support from family abroad and friends on acculturation, discrimination, and mental health among these vulnerable children and youth. Questionnaire data were collected from a population-based multi-ethnic sample involving 895 unaccompanied minors resettled in municipalities in all regions of the country. They met in groups in their local communities. The informants were on average 18.6 years, and had an average length of stay in Norway of 3.5 years. The findings showed that the participants suffered from high levels of ongoing war related intrusive symptoms and depression. Still, at the same time they engaged in adaptation processes that are normative to youth with immigrant backgrounds, in terms of constructing supportive networks and developing culture competence. In accordance with the main effect hypothesis, social support had direct effects on depression and indirect effects by increasing culture competence that may aid the young refugees in dealing with discrimination. However, there were no effects of social support on symptoms of PTSD. The findings give direction to areas of interventions, beyond dealing with the sequel of the traumas the unaccompanied minors have been exposed to, not only for clinicians, but also social workers and school personnel.

    The negative psychological impacts of working with traumatised people are well documented and include vicarious traumatisation (VT): the cumulative effect of identifying with clients' trauma stories that negatively impacts on service providers' memory, emotions, thoughts, and worldviews. More recently, the concept of vicarious resilience (VR) has been also identified: the strength, growth, and empowerment experienced by trauma workers as a consequence of their work. VR includes service providers' awareness and appreciation of their clients' capacity to grow, maintaining hope for change, as well as learning from and reassessing personal problems in the light of clients' stories of perseverance, strength, and growth. This study aimed at exploring the experiences of mental health, physical healthcare, and settlement workers caring for refugees and asylum seekers in South Australia. Using a qualitative method (data-based thematic analysis) to collect and analyse 26 semi-structured face-to-face interviews, we identified four prominent and recurring themes emanating from the data: VT, VR, work satisfaction, and cultural flexibility. These findings-among the first to describe both VT and VR in Australians working with refugee people-have important implications for policy, service quality, service providers' wellbeing, and refugee clients' lives.

    Atomic force microscopy (AFM) has become one of the most widely used techniques for measuring and manipulating various characteristics of materials at the nanoscale. However, there are very limited option for the characterization of field dependence properties. In this work, we demonstrate a versatile variable field module (VFM) with magnetic field up to 1800 Oe for the Asylum Research Cypher system. The magnetic field is changed by adjusting the distance between a rare earth magnet and the AFM probe. A built-in Hall sensor makes it possible to perform in-situ measurements of the field. Rotating the magnet makes it possible to do angular field dependent measurements. The capability of the VFM system is demonstrated by degaussing a floppy disk media with increasing magnetic field. The written bits are erased at about 800 Oe. Angular dependence measurements clearly show the evolution of magnetic domain structures. A completely reversible magnetic force microscopy (MFM) phase contrast is observed when the magnetic field is rotated by 180°. Further demonstration of successful magnetic switching of CoFe2O4 pillars in CoFe2O4-BiFeO3 nanocomposites will be presented and field dependent MFM and piezoresponse force microscopy (PFM) will be discussed. The work at University of Virginia was supported by DARPA under contract no. HR-0011-10-1-0072.

    The current practice of non-consensual medical treatment of hunger-striking asylum seekers in detention needs closer inquiry. An Australian Government regulation empowers the Department of Immigration and Multicultural and Indigenous Affairs (DIMIA) to authorise non-consensual medical treatment for a person in immigration detention if they are at risk of physical harm, but there are doubts about whether the regulation would withstand legal challenge. Authorisation by DIMIA does not compel medical practitioners to enforce treatment if such action is contrary to their "ethical, moral or religious convictions". The World Medical Association has established guidelines for doctors involved in managing people on hunger strikes. The Declaration of Tokyo (1975) and the Declaration of Malta (1991) both prohibit the use of non-consensual force-feeding of hunger strikers who are mentally competent. If called upon to treat hunger strikers, medical practitioners should be aware of their ethical and legal responsibilities, and that they should act independently of government or institutional interests.

    Full Text Available Members of Congress have introduced numerous pieces of legislation in recent years related to refugees, asylum seekers, and other populations of migrants seeking protection in the United States. These bills were drafted in reaction to dramatic events within the United States, at its borders, and around the world. For example, roughly 400,000 children traveling alone and mothers with children have arrived at the southern US border since 2013, many seeking protection from organized crime, gang violence, and threats of human trafficking. Similarly, more than a million refugees from the Middle East, North Africa, and Asia sought to reach safety on the European continent in 2015 alone. Terrorist attacks fueled attempts to curtail the US commitment to offer protection to those fleeing persecution, even when those attacks had no connection to refugees or only tenuous links. And yet existing US law has been left virtually unchanged throughout this tumultuous period. This article describes the significant attempts to enact legislation related to refugees and international migrants since 2013 and examines the reasons why those attempts have not succeeded. It also describes American attitudes toward refugees and assesses whether those attitudes affected the fate of legislation.

    Although women, young people and refugees are vulnerable to sexual and gender-based violence (SGBV) worldwide, little evidence exists concerning SGBV against refugees in Europe. Using community-based participatory research, 223 in-depth interviews were conducted with refugees, asylum seekers and undocumented migrants in Belgium and the Netherlands. Responses were analysed using framework analysis. The majority of the respondents were either personally victimised or knew of a close peer being victimised since their arrival in the European Union. A total of 332 experiences of SGBV were reported, mostly afflicted on them by (ex-)partners or asylum professionals. More than half of the reported violent experiences comprised sexual violence, including rape and sexual exploitation. Results suggest that refugees, asylum seekers and undocumented migrants in Belgium and the Netherlands are extremely vulnerable to violence and, specifically, to sexual violence. Future SGBV preventive measures should consist of rights-based, desirable and participatory interventions, focusing on several socio-ecological levels concurrently.

    Full Text Available Abstract Background Glioblastoma multiforme (GBM is the most common and aggressive brain tumor with poor clinical outcome. Identification and development of new markers could be beneficial for the diagnosis and prognosis of GBM patients. Deregulation of microRNAs (miRNAs or miRs is involved in GBM. Therefore, we attempted to identify and develop specific miRNAs as prognostic and predictive markers for GBM patient survival. Methods Expression profiles of miRNAs and genes and the corresponding clinical information of 480 GBM samples from The Cancer Genome Atlas (TCGA dataset were downloaded and interested miRNAs were identified. Patients’ overall survival (OS and progression-free survival (PFS associated with interested miRNAs and miRNA-interactions were performed by Kaplan-Meier survival analysis. The impacts of miRNA expressions and miRNA-interactions on survival were evaluated by Cox proportional hazard regression model. Biological processes and network of putative and validated targets of miRNAs were analyzed by bioinformatics. Results In this study, 6 interested miRNAs were identified. Survival analysis showed that high levels of miR-326/miR-130a and low levels of miR-323/miR-329/miR-155/miR-210 were significantly associated with long OS of GBM patients, and also showed that high miR-326/miR-130a and low miR-155/miR-210 were related with extended PFS. Moreover, miRNA-323 and miRNA-329 were found to be increased in patients with no-recurrence or long time to progression (TTP. More notably, our analysis revealed miRNA-interactions were more specific and accurate to discriminate and predict OS and PFS. This interaction stratified OS and PFS related with different miRNA levels more detailed, and could obtain longer span of mean survival in comparison to that of one single miRNA. Moreover, miR-326, miR-130a, miR-155, miR-210 and 4 miRNA-interactions were confirmed for the first time as independent predictors for survival by Cox regression model

    Full Text Available Abstract Background MircoRNAs(miRNAs are short, endogenously non-coding RNAs. The abnormal expression of miRNAs may be valuable for the diagnosis and treatment of tumors. Methods To screening the special miRNAs in gastric carcinoma, expression level of miRNAs in gastric carcinoma and normal gaster samples were detected by miRNA gene chip. Then, the expressions of miR-9 and miR-433 in gastric carcinoma tissue and SGC7901 cell line were validated by qRT-PCR. GRB2 and RAB34, targets of miR-433 and miR-9 respectively, were detected by Western blot. Results We found 19 miRNAs and 7 miRNAs were down-regulated and up-regulated respectively. Compared with normal gaster samples, our data showed that miR-9 and miR-433 were down-regulated in gastric carcinoma. Meanwhile, we also found that miR-433 and miR-9 regulated the expression levels of GRB2 and RAB34 respectively. Conclusion Our data show miR-9 and miR-433 was down-regulated in gastric carcinoma. The targets of miR-433 and miR-9 were tumor-associated proteins GRB2 and RAB34 respectively. This result provided the related information of miRNAs in gastric carcinoma.

    2007-10-01

    Full Text Available Abstract Background Medical care for asylum seekers is a complex and critical issue worldwide. It is influenced by social, political, and economic pressures, as well as premigration conditions, the process of migration, and postmigration conditions in the host country. Increasing needs and healthcare costs have led public health authorities to put nurse practitioners in charge of the management of a gatekeeping system for asylum seekers. The quality of this system has never been evaluated. We assessed the competencies of nurses and physicians in identifying the medical needs of asylum seekers and providing them with appropriate treatment that reflects good clinical practice. Methods This cross-sectional descriptive study evaluated the appropriateness of care provided to asylum seekers by trained nurse practitioners in nursing healthcare centers and by physicians in private practices, an academic medical outpatient clinic, and the emergency unit of the university hospital in Lausanne, Switzerland. From 1687 asylum seeking patients who had consulted each setting between June and December 2003, 450 were randomly selected to participate. A panel of experts reviewed their medical records and assessed the appropriateness of medical care received according to three parameters: 1 use of appropriate procedures to identify medical needs (medical history, clinical examination, complementary investigations, and referral, 2 provision of access to treatment meeting medical needs, and 3 absence of unnecessary medical procedures. Results In the nurse practitioner group, the procedures used to identify medical needs were less often appropriate (79% of reports vs. 92.4% of reports; p Conclusion Although the nursing gatekeeping system provides appropriate treatment to asylum seekers, it might be improved with further training in recording medical history and performing targeted clinical examination.

    miRNAs as non-coding, short, double-stranded RNA segments are important for cellular biological functions, such as proliferation, differentiation, and apoptosis. miRNAs mainly contribute to the inhibition of important protein translations through their cleavage or direct repression of target messenger RNAs expressions. In the last decade, miRNAs got in the focus of interest with new publications on miRNAs in the context of different diseases. For many types of cancer or myocardial damage, typical signatures of local or systemically circulating miRNAs have already been described. However, little is known about miRNA expressions and their molecular effect in skeletal diseases. An overview of published studies reporting miRNAs detection linked with skeletal diseases was conducted. All regulated miRNAs were summarized and their molecular interactions were illustrated. This review summarizes the involvement and interaction of miRNAs in different skeletal diseases. Thereby, 59 miRNAs were described to be deregulated in tissue, cells, or in the circulation of osteoarthritis (OA), 23 miRNAs deregulated in osteoporosis, and 107 miRNAs deregulated in osteosarcoma (OS). The molecular influences of miRNAs regarding OA, osteoporosis, and OS were illustrated. Specific miRNA signatures for skeletal diseases are described in the literature. Some overlapped, but also unique ones for each disease exist. These miRNAs may present useful targets for the development of new therapeutic approaches and are candidates for diagnostic evaluations.

    As the number of refugees rises, medical care for refugees, asylum seekers and people with unclear residence status becomes a priority task for our health system. While access to health care is restricted for these groups of people in many German states, Hamburg provides unrestricted access to healthcare for refugees by handing out health insurance cards on arrival. Daily practice shows, however, that adequate medical care is still not always easy to achieve. In this case series we demonstrate that barriers to health care still exist on many levels. We discuss these barriers and further propose strategies to improve and to secure access to adequate health care.

    In 1897 Hamburg was in search of an Oberarzt for the asylum Friedrichsberg who should function as the acting head of the head Wilhelm Reye (1833-1912). This search was part of the intended reformation of the outmoded psychiatric care in Hamburg. During this application procedure the Hamburg Physikus John Wahncau examined all possible candidates and applicants. The article explores the election process by using some sociological categories developed by Pierre Bourdieu (habitus, capital, field). The author argues that not only meritocratic attributes led to the choice of one candidate, but also his functional "fitting" into the field in Hamburg.

    Full Text Available The performance of circulating biomarkers for the diagnosis of hepatocellular carcinoma (HCC is sub-optimal. In this study we tested circulating microRNAs as biomarkers for HCC in cirrhotic patients by performing a two stage study: a discovery phase conducted by microarray and a validation phase performed by qRT-PCR in an independent series of 118 patients. Beside miRNAs emerged from the discovery phase, miR-21, miR-221, miR-519d were also tested in the validation setting on the basis of literary and tissue findings. Deregulated microRNAs were assayed in HCC-derived cells in the intracellular compartment, cell culture supernatant and exosomal fraction. Serum and tissue microRNA levels were compared in 14 patients surgically treated for HCC. From the discovery study, it emerged that seven circulating microRNAs were differentially expressed in cirrhotic patients with and without HCC. In the validation set, miR-939, miR-595 and miR-519d were shown to differentiate cirrhotic patients with and without HCC. MiR-939 and miR-595 are independent factors for HCC. ROC curves of miR-939, miR-595 and miR-519d displayed that AUC was higher than AFP. An exosomal secretion of miR-519d, miR-21, miR-221 and miR-1228 and a correlation between circulating and tissue levels of miR-519d, miR-494 and miR-21 were found in HCC patients. Therefore, we show that circulating microRNAs deserve attention as non-invasive biomarkers in the diagnostic setting of HCC and that exosomal secretion contributes to discharging a subset of microRNAs into the extracellular compartment.

  1. Reference miRNAs for miRNAome analysis of urothelial carcinomas.

    Directory of Open Access Journals (Sweden)

    Nadine Ratert

    Full Text Available BACKGROUND/OBJECTIVE: Reverse transcription quantitative real-time PCR (RT-qPCR is widely used in microRNA (miRNA expression studies on cancer. To compensate for the analytical variability produced by the multiple steps of the method, relative quantification of the measured miRNAs is required, which is based on normalization to endogenous reference genes. No study has been performed so far on reference miRNAs for normalization of miRNA expression in urothelial carcinoma. The aim of this study was to identify suitable reference miRNAs for miRNA expression studies by RT-qPCR in urothelial carcinoma. METHODS: Candidate reference miRNAs were selected from 24 urothelial carcinoma and normal bladder tissue samples by miRNA microarrays. The usefulness of these candidate reference miRNAs together with the commonly for normalization purposes used small nuclear RNAs RNU6B, RNU48, and Z30 were thereafter validated by RT-qPCR in 58 tissue samples and analyzed by the algorithms geNorm, NormFinder, and BestKeeper. PRINCIPAL FINDINGS: Based on the miRNA microarray data, a total of 16 miRNAs were identified as putative reference genes. After validation by RT-qPCR, miR-101, miR-125a-5p, miR-148b, miR-151-5p, miR-181a, miR-181b, miR-29c, miR-324-3p, miR-424, miR-874, RNU6B, RNU48, and Z30 were used for geNorm, NormFinder, and BestKeeper analyses that gave different combinations of recommended reference genes for normalization. CONCLUSIONS: The present study provided the first systematic analysis for identifying suitable reference miRNAs for miRNA expression studies of urothelial carcinoma by RT-qPCR. Different combinations of reference genes resulted in reliable expression data for both strongly and less strongly altered miRNAs. Notably, RNU6B, which is the most frequently used reference gene for miRNA studies, gave inaccurate normalization. The combination of four (miR-101, miR-125a-5p, miR-148b, and miR-151-5p or three (miR-148b, miR-181b, and miR-874

    2015-01-01

    Full Text Available The focus of this review is to provide an update on the progress of microRNAs (miRNAs as potential biomarkers for lung cancer. miRNAs are single-stranded, small noncoding RNAs that regulate gene expression and show tissue-specific signatures. Accumulating evidence indicates that miRNA expression patterns represent the in vivo status in physiology and disease. Moreover, miRNAs are stable in serum and other clinically convenient and available tissue sources, so they are being developed as biomarkers for cancer and other diseases. Cancer is currently the primary driver of the field, but miRNA biomarkers are being developed for many other diseases such as cardiovascular and central nervous system diseases. Here we examine the framework and scope of the miRNA landscape as it specifically relates to the translation of miRNA expression patterns/signatures into biomarkers for developing diagnostics for lung cancer. We focus on examining tumor cytosol miRNAs, fluid miRNAs, and exosome miRNAs in lung cancer, the connections among these miRNAs, and the potential of miRNA biomarkers for the development of diagnostics. In lung cancer, miRNAs have been studied in both cell populations and in the circulation. However, a major challenge is to develop biomarkers to monitor cancer development and to identify circulating miRNAs that are linked to cancer stage. Importantly, the fact that miRNAs can be successfully harvested from biological fluids allows for the development of biofluid biopsies, in which miRNAs as circulating biomarkers can be captured and analyzed ex vivo. Our hope is that these minimally invasive entities provide a window to the in vivo milieu of the patients without the need for costly, complex invasive procedures, rapidly moving miRNAs from research to the clinic.

    have generated custom data sets containing expression information of 54 miRNA families sharing the same seed match. We have developed a novel strategy for correlating miRNAs with individual genes based on a summed Pearson Correlation Coefficient (sPCC) that mimics an in silico titration experiment......micro(mi)RNAs are small non-coding RNAs that negatively regulate expression of most mRNAs. They are powerful regulators of various differentiation stages, and the expression of genes that either negatively or positively correlate with expressed miRNAs is expected to hold information....... By focusing on the genes that correlate with the expression of miRNAs without necessarily being direct targets of miRNAs, we have clustered miRNAs into different functional groups. This has resulted in the identification of three novel miRNAs that are linked to the epithelial-to-mesenchymal transition (EMT...

    Plant microRNAs (miRNAs) post-transcriptionally regulate target gene expression to modulate growth and development and biotic and abiotic stress responses. By analyzing small RNA deep sequencing data in combination with the genome sequence, we identified 75 conserved miRNAs and 11 novel miRNAs. Their target genes were also predicted. For most conserved miRNAs, the miRNA-target pairs were conserved across plant species. In addition to these conserved miRNA-target pairs, we also identified some papaya-specific miRNA-target regulatory pathways. Both miR168 and miR530 target the Argonaute 1 gene, indicating a second autoregulatory mechanism for miRNA regulation. A non-conserved miRNA was mapped within an intron of Dicer-like 1 (DCL1), suggesting a conserved homeostatic autoregulatory mechanism for DCL1 expression. A 21-nt miRNA triggers secondary siRNA production from its target genes, nucleotide-binding site leucine-rich repeat protein genes. Certain phased-miRNAs were processed from their conserved miRNA precursors, indicating a putative miRNA evolution mechanism. In addition, we identified a Carica papaya-specific miRNA that targets an ethylene receptor gene, implying its function in the ethylene signaling pathway. This work will also advance our understanding of miRNA functions and evolution in plants.

    Full Text Available Abstract Background MicroRNAs (miRNAs are a novel class of gene expression regulators implicated in cancer biology. Neuroblastoma (NB is an embryonal tumour consisting of neural crest-derived undifferentiated cells and is characterised by variable clinical courses ranging from spontaneous regression to therapy-resistant progression. Recent advances identified a subset of miRNAs with putative function in NB biology. However, the full repertoire of miRNAs expressed in NBs is not available. Results We describe miRNA profiles of 13 NB specimens and 2 NB cell lines as determined by miRNA cloning. A total of 3153 sequences were sequenced and analysed by a miRNA prediction tool (miRpredict. Our library covered 27% miRNAs known to date. 39 reads corresponding to 25 individual sequences were classified as novel miRNAs, including miRNA* species of 10 known miRNAs. Expression of 5 new miRNA* forms and 8 individual sequences was supported by Northern blotting. Most of the novel miRNA genes are not related to each other and do not share homology with the annotated sequences in the public miRNA database, but they are conserved within mammals or have close homologues in primates genomes. Conclusion We provide evidence for 29 new miRNA and miRNA-like sequences (24 novel sequences and 5 miRNAs discovered initially in other species. Some of these newly identified sequences reside within frequently altered chromosomal regions in NB tumours and may play a role in NB biology.

    Full Text Available Se reitera el incremento que en los últimos años ha tenido la población de adultos mayores, hecho que repercute en el número también cada vez más alto de personas residentes en asilos para ancianos, lugares que por lo regular dependen del estado y cuyas características tanto materiales como su infraestructura en cuanto a personal especializado para atender a las personas que ahí viven, deja mucho que desear. Este último aspecto es el punto cardinal de este trabajo, ya que los cuidadores, trátese de enfermeras, psicólogo, médicos, trabajadoras sociales, entre otros, realizan un papel crucial en el funcionamiento de tales instituciones. El cuidador, al igual que los residentes, es un ser humano, con una carga inherente a la labor que realiza y que, además, transita por todas las emociones o conflictos que implica desempeñar su puesto, al igual que los que cuida, necesita ser cuidado y atendido para el logro del bienestar de ambos.This article underlines the increase in the population of elderly persons that has occurred in recent years and has resulted in ever-increasing numbers of residents living in asylums for the aged, or old people’s homes. Such institutions are generally dependent on the state, and their material characteristics as well as their infrastructure in regard to the specialized personnel for attending to the people residing there leave much to be desired. This last aspect is the central point of this work since the caretakers, be they nurses, psychologists, doctors, social workers or others, perform a crucial role in the functioning of such institutions. The caretaker, like the residents, is a human being with a duty that is inherent in his/her work and who, in addition, is subject to all the emotions or conflicts that the job implies. Just like the persons under his care, he requires care and attention in order to maintain the well-being of all those concerned.

  12. EMDR versus stabilisation in traumatised asylum seekers and refugees: results of a pilot study

    2011-08-01

    Full Text Available Traumatised asylum seekers and refugees are clinically considered a complex population. Discussion exists on whether with this population treatment guidelines for post-traumatic stress disorder (PTSD should be followed and Trauma-Focused Cognitive-Behavioural Therapy (TF-CBT or Eye Movement Desensitisation and Reprocessing (EMDR should be applied, or whether a phased model starting with stabilisation is preferable. Some clinicians fear that trauma-focused interventions may lead to unmanageable distress or may be ineffective. While cognitive-behavioural interventions have been found to be effective with traumatised refugees, no studies concerning the efficacy of EMDR with this population have been conducted as yet.In preparation for a randomised trial comparing EMDR and stabilisation with traumatised refugees, a pilot study with 20 participants was conducted. The objective was to examine feasibility of participation in a randomised trial for this complex population and to examine acceptability and preliminary efficacy of EMDR.Participants were randomly allocated to 11 sessions of either EMDR or stabilisation. Symptoms of PTSD (SCID-I, HTQ, depression and anxiety (HSCL-25, and quality of life (WHOQOL-BREF were assessed at pre- and post-treatment and 3-month follow-up.Participation of traumatised refugees in the study was found feasible, although issues associated with complex traumatisation led to a high pre-treatment attrition and challenges in assessments. Acceptability of EMDR was found equal to that of stabilisation with a high drop-out for both conditions. No participants dropped out of the EMDR condition because of unmanageable distress. While improvement for EMDR participants was small, EMDR was found to be no less efficacious than stabilisation. Different symptom courses between the two conditions, with EMDR showing some improvement and stabilisation showing some deterioration between pre-treatment and post-treatment, justify the conduct

    MicroRNAs (miRNAs) are small, non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. In the brain, a large number of miRNAs are expressed and there is a growing body of evidence demonstrating that miRNAs are essential for brain development and neuronal function. Conditional knockout studies of the core components in the miRNA biogenesis pathway, such as Dicer and DGCR8, have demonstrated a crucial role for miRNAs during the development of the central nervous system. Furthermore, mice deleted for specific miRNAs and miRNA-clusters demonstrate diverse functional roles for different miRNAs during the development of different brain structures. miRNAs have been proposed to regulate cellular functions such as differentiation, proliferation and fate-determination of neural progenitors. In this review we summarise the findings from recent studies that highlight the importance of miRNAs in brain development with a focus on the mouse model. We also discuss the technical limitations of current miRNA studies that still limit our understanding of this family of non-coding RNAs and propose the use of novel and refined technologies that are needed in order to fully determine the impact of specific miRNAs in brain development. - Highlights: • miRNAs are essential for brain development and neuronal function. • KO of Dicer is embryonically lethal. • Conditional Dicer KO results in defective proliferation or increased apoptosis. • KO of individual miRNAs or miRNA families is necessary to determine function.

    The right to health care is significant for asylum seekers, particularly as many of them have experienced traumatic life events in their home country, during flight or in their host country. Post-migration living conditions have more impact than pre-migration conditions on ill health among asylum seekers, which underscores the importance of health care-related refugee reception policies. The purpose of this article is to explore the perceived meaning of comprehensive health information provided by a nurse to Arabic- and Somali-speaking adult asylum seekers, in a Swedish context, during its introduction at the Migration Board. In our study, the endpoint was whether asylum seekers found such health information relevant, understandable and respectful. Following an oral presentation, participants filled in a questionnaire consisting of three close-ended questions. A total of 39 groups of presentation attendees included 626 asylum seekers (415 Arabic- and 211 Somali-speaking). Data were analysed with descriptive statistics. Comments underwent content analysis. We also present some socio-demographic data on these asylum seekers. Independently of gender and language, the participants expressed their gratitude for and the meaningfulness of receiving professional, fact-based information, as well as being treated with concern and respect. They indicated a great need for this and felt relieved by being listened to. They liked the pedagogic group method, the opportunity for dialogue and to practice exercising their rights. These promising results indicate that exercising the asylum-seekers' right to receive such health information would improve future reception policies not only in Sweden, but throughout the EU. A renewed focus on communication and pedagogic skills, instead of just cultural training, should be considered for health care professionals assisting asylum seekers.

    N = 63 refugees and asylum seekers, 27 women and 36 men with a mean age of 33.08 years (SD = 10.3) from Chechnya and Afghanistan were granted sponsorships for six months and were randomized to an intervention and a waiting-list control group. Only participants with a history of traumatization benefited from the intervention. For the traumatized sub-sample, sponsorships led to a significant and stable decrease in anxiety, depression, and psychological problems as compared to the control group, with effect sizes comparable to those of psychotherapy. The effects being rather palliative than instrumental, however, sponsorships did not instigate improvements in acculturation, societal contact, or coping capability. Women benefited more from the intervention than men, and Afghans more than Chechen.

    2012-05-01

    Full Text Available This paper, based on broader discussions surrounding gender violence and immigration in the U.S., provides critical information on the historical context of extreme violence against women and femicide plaguing Central American societies today. Drawing on experiences of precedent setting cases of Guatemalan women, the authors offer suggestions for culturally specific treatment of and support for women who seek asylum in the U.S. out of justified fear for their and their family members’ lives should they return to their country of origin. The arguments presented are predicated on the belief that women worldwide share experiences of myriad forms of male domination and gender inequality which, however, play out differently on their bodies and lives in ways that must be accounted for in our attempt to offer them appropriate care and assist them in creating the tools they need to change their circumstances.

    Attempts to maintain the native lake trout (Salvelinus namaycush) population in Lake Ontario by stocking fry failed and the species was extirpated by the 1950s. Hatchery fish stocked in the 1960s did not live to maturity because of sea lamprey (Petromyzon marinus) predation and incidental commercial harvest. Suppression of sea lampreys began with larvicide treatments of Lake Ontario tributaries in 1971 and was enhanced when the tributaries of Oneida Lake and Lake Erie were treated in the 1980s. Annual stocking of hatchery fish was resumed with the 1972 year class and peaked at about 1.8 million yearlings and 0.3 million fingerlings from the 1985–1990 year classes. Survival of stocked yearlings declined over 50% in the 1980 s and was negatively correlated with the abundance of lake trout > 550 mm long (r = −0.91, P < 0.01, n = 12). A slot length limit imposed by the State of New York for the 1988 fishing season reduced angler harvest. Angler harvest in Canadian waters was 3 times higher in eastern Lake Ontario than in western Lake Ontario. For the 1977–1984 year classes, mean annual survival rate of lake trout age 6 and older was 0.45 (range: 0.35–0.56). In U.S. waters during 1985–1992, the total number of lake trout harvested by anglers was about 2.4 times greater than that killed by sea lampreys. The number of unmarked lake trout < 250 mm long in trawl catches in 1978–1992 was not different from that expected due to loss of marks and failure to apply marks at the hatchery, and suggested that recruitment of naturally-produced fish was nil. However, many of the obstacles which may have impeded lake trout rehabilitation in Lake Ontario during the 1980s are slowly being removed, and there are signs of a general ecosystem recovery. Significant recruitment of naturally produced lake trout by the year 2000, one interim objective of the rehabilitation plan for the Lake, may be achieved.

    miRNAs are small non-coding RNAs with average length of ∼21 bp. miRNA formation seems to be dependent upon multiple factors besides Drosha and Dicer, in a tissue/stage-specific manner, with interplay of several specific binding factors. In the present study, we have investigated transcription factor binding sites in and around the genomic sequences of precursor miRNAs and RNA-binding protein (RBP) sites in miRNA precursor sequences, analysed and tested in comprehensive manner. Here, we report that miRNA precursor regions are positionally enriched for binding of transcription factors as well as RBPs around the 3′ end of mature miRNA region in 5′ arm. The pattern and distribution of such regulatory sites appears to be a characteristic of precursor miRNA sequences when compared with non-miRNA sequences as negative dataset and tested statistically. When compared with 1 kb upstreamregions, a sudden sharp peak for binding sites arises in the enriched zone near the mature miRNA region. An expression-data-based correlation analysis was performed between such miRNAs and their corresponding transcription factors and RBPs for this region. Some specific groups of binding factors and associated miRNAs were identified. We also identified some of the overrepresented transcription factors and associated miRNAs with high expression correlation values which could be useful in cancer-related studies. The highly correlated groups were found to host experimentally validated composite regulatory modules, in which Lmo2-GATA1 appeared as the predominant one. For many of RBP–miRNAs associations, co-expression similarity was also evident among the associated miRNA common to given RBPs, supporting the Regulon model, suggesting a common role and common control of these miRNAs by the associated RBPs. Based on our findings, we propose that the observed characteristic distribution of regulatory sites in precursor miRNA sequence regions could be critical inmiRNA transcription, processing

    MicroRNAs (miRNAs) are a class of small non-coding regulatory RNAs that regulate gene expression by guiding target mRNA cleavage or translational inhibition. Drought is a common environmental stress influencing crop growth and development. To date, it has been reported that a number of plant miRNA are involved in drought stress response. In this study, we comparatively investigated drought stress-responsive miRNAs in the root and leaf of bread wheat (Triticum aestivum cv. Sivas 111/33) by miRNA microarray screening. miRNA microarray analysis showed that 285 miRNAs (207 upregulated and 78 downregulated) and 244 miRNAs (115 upregulated and 129 downregulated) were differentially expressed in leaf and root tissues, respectively. Among the differentially expressed miRNAs, 23 miRNAs were only expressed in the leaf and 26 miRNAs were only expressed in the root of wheat growth under drought stress. Upon drought treatment, expression of miR159, miR160, miR166, miR169, miR172, miR395, miR396, miR408, miR472, miR477, miR482, miR1858, miR2118, and miR5049 were found to be significantly differentiated in bread wheat. The regulatory network analysis showed that miR395 has connections with a number of target transcripts, and miR159 and miR319 share a number of target genes. Drought-tolerant and drought-sensitive wheat cultivars showed altered expression pattern upon drought stress in terms of investigated miRNA and their target transcript expression level.

    Full Text Available Cardiovascular diseases and cancers are the leading causes of morbidity and mortality in the world. MicroRNAs (miRNAs are short non-coding RNAs that primarily repress target mRNAs. Here, miR-24, miR-125b, miR-195 and miR-214 were selected as representative cardio-miRs that are upregulated in human heart failure. To bridge the gap between miRNA studies in cardiology and oncology, the targets and functions of these miRNAs in cardiovascular diseases and cancers will be reviewed. ACVR1B, BCL2, BIM, eNOS, FGFR3, JPH2, MEN1, MYC, p16 and ST7L are miR-24 targets that have been experimentally validated in human cells. ARID3B, BAK1, BCL2, BMPR1B, ERBB2, FGFR2, IL6R, MUC1, SITR7, Smoothened, STAT3, TET2 and TP53 are representative miR-125b targets. ACVR2A, BCL2, CCND1, E2F3, GLUT3, MYB, RAF1, VEGF, WEE1 and WNT7A are representative miR-195 targets. BCL2L2, ß-catenin, BIM, CADM1, EZH2, FGFR1, NRAS, PTEN, TP53 and TWIST1 are representative miR-214 targets. miR-125b is a good cardio-miR that protects cardiomyocytes; miR-195 is a bad cardio-miR that elicits cardiomyopathy and heart failure; miR-24 and miR-214 are bi-functional cardio-miRs. By contrast, miR-24, miR-125b, miR-195 and miR-214 function as oncogenic or tumor suppressor miRNAs in a cancer (subtype-dependent manner. Circulating miR-24 is elevated in diabetes, breast cancer and lung cancer. Circulating miR-195 is elevated in acute myocardial infarction, breast cancer, prostate cancer and colorectal adenoma. Circulating miR-125b and miR-214 are elevated in some cancers. Cardio-miRs and onco-miRs bear some similarities in functions and circulation profiles. Because circulating miRNA profiles are modulated by genetic and environmental factors and are dysregulated by genetic and epigenetic alterations in somatic cells, circulating miRNA association studies (CMASs within several thousands of cases each for common non-cancerous diseases and major cancers are necessary for miRNA-based diagnostics.

  5. Estimation of a Trophic State Index for selected inland lakes in Michigan, 1999–2013

    Fuller, Lori M.; Jodoin, Richard S.

    2016-03-11

    A 15-year estimated Trophic State Index (eTSI) for Michigan inland lakes is available, and it spans seven datasets, each representing 1 to 3 years of data from 1999 to 2013. On average, 3,000 inland lake eTSI values are represented in each of the datasets by a process that relates field-measured Secchi-disk transparency (SDT) to Landsat satellite imagery to provide eTSI values for unsampled inland lakes. The correlation between eTSI values and field-measured Trophic State Index (TSI) values from SDT was strong as shown by R2 values from 0.71 to 0.83. Mean eTSI values ranged from 42.7 to 46.8 units, which when converted to estimated SDT (eSDT) ranged from 8.9 to 12.5 feet for the datasets. Most eTSI values for Michigan inland lakes are in the mesotrophic TSI class. The Environmental Protection Agency (EPA) Level III Ecoregions were used to illustrate and compare the spatial distribution of eTSI classes for Michigan inland lakes. Lakes in the Northern Lakes and Forests, North Central Hardwood Forests, and Southern Michigan/Northern Indiana Drift Plains ecoregions are predominantly in the mesotrophic TSI class. The Huron/Erie Lake Plains and Eastern Corn Belt Plains ecoregions, had predominantly eutrophic class lakes and also the highest percent of hypereutrophic lakes than other ecoregions in the State. Data from multiple sampling programs—including data collected by volunteers with the Cooperative Lakes Monitoring Program (CLMP) through the Michigan Department of Environmental Quality (MDEQ), and the 2007 National Lakes Assessment (NLA)—were compiled to compare the distribution of lake TSI classes between each program. The seven eTSI datasets are available for viewing and download with eSDT from the Michigan Lake Water Clarity Interactive Map Viewer at http://mi.water.usgs.gov/projects/RemoteSensing/index.html.

    This paper deals with two examples of a particular patient's activity at the Friedrichsberg Asylum in Hamburg in the beginning of the 20th century. Two multilingual patients assumed the function of interpreters in each case for a foreign fellow patient. They were involved to a great extent in the documentation of the medical histories. Conversations and interrogations carried out by them and recorded by their own hand are passed down in the medical files of their foreign-language fellow patients. After some preliminary remarks about the Friedrichsberg Asylum and its patients, the various activities of patients in the psychiatric institution and the importance of the patients' manner of speaking for the psychiatric diagnosis, the two cases are described in detail. The patient-interpreters were perceived as border-crossers, as "Figures of the Third".

    The objective of this work is to analyze the daily life of 'tubercular children'" coming from the city of Buenos Aires. They were hospitalized in the Maritime Asylum located in the seaside city of Mar del Plata, 400 kilometers from the capital. In 1893, in the Charitable Society of the Federal Capital, the idea arose of founding a hospital and maritime asylum for children ill with osseous tuberculosis in general, weak and convalescing children and the treatment of patients with extra-pulmonary tuberculosis. This paper attempts to advance the understanding of two inter-related topics: on the one hand, the characteristics of the institutionalized meddling of the Charitable Society, and, on the other, the experience that these tubercular children had in this institution.

    2014-01-01

    The understanding of RNA in regulating gene expression has exploded over the past 15 years. MicroRNAs (miRNAs) have vastly expanded the role of RNA in gene regulation beyond spliceosomal, ribosomal, and messenger RNAs. Approximately one half of miRNAs are polycistronic, where two or more miRNAs are encoded on a single pri-miRNA transcript, termed a miRNA cluster. The six miRNAs of the miR-17~92 cluster are contained within a ~800 nucleotide region within intron 3 of the cl13orf25 ~7 kb pri-miRNA transcript. We recently reported on the tertiary structured domain of miR-17~92 and its role in modulating miRNA biogenesis. The key finding was that the cluster structure explained the differential processing of the miRNA hairpins by Drosha. This work demonstrated the need to consider pri-miRNA tertiary structure in miRNA biogenesis. Since biochemical structure probing is typically performed on relatively short RNAs (≤200 nucleotides), we had to adapt these methodologies for application on large RNAs (~800 nucleotide miR-17~92 pri-miRNA). We present here our adaptation of a protection footprinting method using ribonucleases to probe the structure of the ~800 nucleotide miR-17~92 pri-miRNA. We outline the technical difficulties involved in probing large RNAs and data visualization using denaturing polyacrylamide gel electrophoresis and how we adapted the existing approaches to probe large RNAs. The methodology outlined here is generally applicable to large RNAs including long noncoding RNAs (lncRNA).

  12. Circulating miRNA and cancer diagnosis

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    miRNAs are a class of small RNA molecules with regulatory function, and play an important role in tumor development and progression. It has been demonstrated that tumor-derived miRNAs exist in the circulating nucleic acids of cancer patients. This phenomenon implies that detection of the circulating miRNA may be an effective method for non-invasive diagnosis of cancer. In this review, we summarize the applications of the circulating miRNA as biomarkers in cancer diagnosis, as well as the latest research progress in this area.

    MicroRNAs (miRNAs) regulate a wide range of cellular and developmental processes through gene expression suppression or mRNA degradation. Experimentally validated miRNA gene targets are often reported in the literature. In this paper, we describe miRTex, a text mining system that extracts miRNA-target relations, as well as miRNA-gene and gene-miRNA regulation relations. The system achieves good precision and recall when evaluated on a literature corpus of 150 abstracts with F-scores close to 0.90 on the three different types of relations. We conducted full-scale text mining using miRTex to process all the Medline abstracts and all the full-length articles in the PubMed Central Open Access Subset. The results for all the Medline abstracts are stored in a database for interactive query and file download via the website at http://proteininformationresource.org/mirtex. Using miRTex, we identified genes potentially regulated by miRNAs in Triple Negative Breast Cancer, as well as miRNA-gene relations that, in conjunction with kinase-substrate relations, regulate the response to abiotic stress in Arabidopsis thaliana. These two use cases demonstrate the usefulness of miRTex text mining in the analysis of miRNA-regulated biological processes.

    Full Text Available Abstract Background Human rights violations have adverse consequences for health. However, to date, there remains little empirical evidence documenting this association, beyond the obvious physical and psychological effects of torture. The primary aim of this study was to investigate whether Australian asylum policies and practices, which arguably violate human rights, are associated with adverse health outcomes. Methods We designed a mixed methods study to address the study aim. A cross-sectional survey was conducted with 71 Iraqi Temporary Protection Visa (TPV refugees and 60 Iraqi Permanent Humanitarian Visa (PHV refugees, residing in Melbourne, Australia. Prior to a recent policy amendment, TPV refugees were only given temporary residency status and had restricted access to a range of government funded benefits and services that permanent refugees are automatically entitled to. The quantitative results were triangulated with semi-structured interviews with TPV refugees and service providers. The main outcome measures were self-reported physical and psychological health. Standardised self-report instruments, validated in an Arabic population, were used to measure health and wellbeing outcomes. Results Forty-six percent of TPV refugees compared with 25% of PHV refugees reported symptoms consistent with a diagnosis of clinical depression (p = 0.003. After controlling for the effects of age, gender and marital status, TPV status made a statistically significant contribution to psychological distress (B = 0.5, 95% CI 0.3 to 0.71, p ≤ 0.001 amongst Iraqi refugees. Qualitative data revealed that TPV refugees generally felt socially isolated and lacking in control over their life circumstances, because of their experiences in detention and on a temporary visa. This sense of powerlessness and, for some, an implicit awareness they were being denied basic human rights, culminated in a strong sense of injustice. Conclusion Government asylum policies

    2011-01-01

    Multiple myeloma (MM) is an incurable plasma cell malignancy and is the second most common hematological cancer. It is characterized by complex, recurrent genetic and epigenetic abnormalities. Recent publications have linked miRNAs, a novel class of gene regulators to cancer including MM. miRNAs are about 20 nucleotide, single strand, non-coding RNAs that repress gene expression by mRNA degradation or translational repression. Aberrant miRNA expression profiles have been described in MM, and their functional roles in MM pathogenesis are being increasingly recognized. This review summarizes the current literature on the role of miRNAs in MM and offers perspectives on future research and utilization of miRNAs in MM management.

  20. MiRNA Biogenesis and Intersecting Pathways

    DEFF Research Database (Denmark)

    Ben Chaabane, Samir

    MicroRNAs (miRNAs) are small non-coding RNAs that function as guide molecules in RNA silencing. Plant miRNAs are critical for plant growth, development and stress response, and are processed in Arabidopsis from primary miRNA transcripts (pri-miRNAs) by the endonuclease activity of the DICER-LIKE1...... of action and turnover. During my PhD period we have shown that the STA1 protein, a factor for pre-mRNA splicing and mRNA stability, is specifically involved in the splicing of pri-miRNAs and in the modulation of DCL1 transcript levels. Also, we established a novel and essential regulatory network in which...

    Lerner, Astrid; Steinberg, Holger

    2011-08-01

    On the basis of archival sources and primary literature the study exemplifies the history of one form of extramural social psychiatric care on the example of one particular institution, the town asylum of Leipzig-Dösen. Family care was introduced in Leipzig in 1904 by Georg Lehmann, primarily as an alternative treatment option. After initial opposition among the local population had been defeated, this form of treatment was soon quite accepted. Due to the socioeconomic changes as a result of World War I, the extent of family care was downsized. From 1940 family care in Dösen was abolished, due to a change in ideology. Part of the patients previously in family care fell victim to the National socialist T-4 programme to murder chronically mental ill. However, this study could also prove that at least one third of these patients survived. It can only be presumed to which extent this was due to their physical work being needed as a result of war shortages.

    Full Text Available Background: Traumatised asylum seekers and refugees may present with significant and complex mental health problems as a result of prolonged, extreme, and multiple traumatic events. This is further complicated by ongoing complex social circumstances. Concepts: In our work at the Traumatic Stress Clinic (TSC, the understanding afforded by the concept of complex posttraumatic stress disorder (PTSD together with the related notion of a phased treatment model, provides a useful framework for organising our work with this population. Clinical Applications: An explication of complex PTSD as it applies to our client group is presented, followed by a description of our phased treatment model and an outline of the core principles, which guide our clinical approach. Our symptom management and stabilisation groups have been developed and refined over time and draw on techniques from a variety of cognitive behavioural therapies. These are described in some detail with illustrative clinical case vignettes. Conclusion: This paper concludes with some reflections on the challenges inherent to working with this complex client group.

  4. Political representation for social justice in nursing: lessons learned from participant research with destitute asylum seekers in the UK.

    2016-09-01

    The concept of social justice is making a revival in nursing scholarship, in part in response to widening health inequalities and inequities in high-income countries. In particular, critical nurse scholars have sought to develop participatory research methods using peer researchers to represent the 'voice' of people who are living in marginalized spaces in society. The aim of this paper is to report on the experiences of nurse and peer researchers as part of a project to explore the experiences of people who find themselves destitute following the asylum process in the UK. In seeking to explore social injustice, three challenges are identified: lack of a robust political theory, institutional/professional constraints and an absence of skills to engage with the politics of social (in)justice. Each challenge is presented, opposing voices outlined and some possible solutions are suggested. The work of political theorist Nancy Fraser is used as a conceptual framework, in particular her focus on mis/framing and political representation for social justice. In addition, it is suggested that social justice needs to be further embedded in nursing policy and curriculum. Finally, nurses are encouraged to develop practical political skills to engage with both politics and the media in a neoliberal globalizing world.

    Literature highlights the potential for refugees to contribute to the labour force of receiving countries. Such a contribution may be welcomed in sectors, such as social care, where demand for labour is increasing and high vacancy rates exist. This article reports on empirical data examining the potential of refugee communities to work in social care in England. The analysis is based primarily on 20 interviews with refugees and asylum seekers and five representatives of refugee support groups, conducted in 2008-2009. The findings of this sub-study are set within results obtained from other interviews as part of a multi-methods study examining the contribution of migrants to the English care sector. In-depth interviews were analysed thematically, guided by a theoretical framework linking employment, migration and the nature of care work. The findings highlight a general willingness of refugee participants to join the care workforce. Individual and structural barriers to increased employability were identified, as well as possible strategies to overcome them. Although the findings and discussions presented are based on data collected in England and are specific to the care sector, most are more generalisable and may inform strategies aiming at maximising refugees' employability in other sectors and in other developed states.

    This article analyzes the complex political environment of US immigration and refugee policies in which tensions exist, especially with regard to Central America and the Caribbean. Recommendations for managing it more effectively in the future are discussed. Several western countries, including the US, have implemented stricter restriction policies as a result of the perceived threats to their economies and cultural homogeneity. In general, US immigration policy has addressed both economic concerns and domestic pressures, whereas US refugee policy has reflected foreign policy concerns. As a result of these policies, there has been an increasing number of immigrants from Mexico, as well as huge numbers of refugees from Cuba and Nicaragua. Yet, there has been limited acceptance of asylum seekers from Haiti, El Salvador and Guatemala. Among the policies passed by the US Congress to reduce illegal immigration and limit assistance to legal immigrants were the Welfare Reform Act, Illegal Immigration Reform, Immigration Responsibility Act of 1996, and the Proposition 187 movement. Revisions in the procedures of the Immigration and Naturalization Service were also made.

    The levels of expression of O6-methylguanine-DNA methyltransferase (MGMT) are relevant in predicting the response to the alkylating chemotherapy in patients affected by glioblastoma. MGMT promoter methylation and the published MGMT regulating microRNAs (miRNAs) do not completely explain the expression pattern of MGMT in clinical glioblastoma specimens. Here we used a genome-wide microarray-based approach to identify MGMT regulating miRNAs. Our screen unveiled three novel MGMT regulating miRNAs, miR-127-3p, miR-409-3p, and miR-124-3p, in addition to the previously identified miR-181d-5p. Transfection of these three novel miRNAs into the T98G glioblastoma cell line suppressed MGMT mRNA and protein expression. However, their MGMT- suppressive effects are 30-50% relative that seen with miR-181d-5p transfection. In silico analyses of The Cancer Genome Atlas (TCGA) and Chinese Glioma Genome Atlas (CGGA) revealed that miR-181d-5p is the only miRNA that consistently exhibited inverse correlation with MGMT mRNA expression. However, statistical models incorporating both miR-181d-5p and miR-409-3p expression better predict MGMT expression relative to models involving either miRNA alone. Our results confirmed miR-181d-5p as the key MGMT-regulating miRNA. Other MGMT regulating miRNAs, including the miR-409-3p identified in this report, modify the effect of miR-181d-5p on MGMT expression. MGMT expression is, thus, regulated by cooperative interaction between key MGMT-regulating miRNAs.

    Purpose Insufficient sensitivity and specificity prevent the use of most existing biomarkers for early detection of breast cancer. Recently, it was reported that serum microRNAs (miRNAs) may be potential biomarkers in many cancer diseases. In this study, we investigated whether serum levels of 5 miRNAs including miR-21, miR-125b, miR-145, miR-155, and miR-365 could discriminate breast cancer patients and healthy controls. Methods Serum levels of miRNAs were measured by using quantitative real-time polymerase chain reaction in 99 breast cancer patients and 21 healthy controls. The abundance change of serum miRNAs were also evaluated following surgical resection in 20 breast cancer patients. Receiver operating characteristic (ROC) curve analysis was performed to assess the sensitivity and specificity of miRNAs as diagnostic biomarkers. Results Serum levels of miR-21 and miR-155 was significantly higher, while miR-365 was significantly lower in breast cancer as compared with healthy controls. The serum levels of miR-21 and miR-155 significantly decreased following surgical resection. Additionally, the serum level of miR-155 at stages I and II was significantly higher compared to stage III. The serum miR-145 level was remarkably higher in progesterone receptor (PR)-positive patients than PR-negative. The positivity of miR-21, miR-155, and miR-365 was high compared to CA 153 and CEA in breast cancer. ROC curve analyses of a combination of miR-21, miR-155, and miR-365 yielded much higher area under curve and enhanced sensitivity and specificity in comparison to each miRNA alone. Conclusion The combination of serum miR-21/miR-155/miR-365 may potentially serve as a sensitive and specific biomarker that enables differentiation of breast cancer from healthy controls.

    Full Text Available Epithelial-mesenchymal interactions play a crucial role in branching morphogenesis, but very little is known about how endothelial cells contribute to this process. Here, we examined how anti-angiogenic miR-221 and pro-angiogenic miR-130a affect airway and vascular development in the fetal lungs. Lung-specific effects of miR-130a and miR-221 were studied in mouse E14 whole lungs cultured for 48 hours with anti-miRs or mimics to miR-130a and miR-221. Anti-miR 221 treated lungs had more distal branch generations with increased Hoxb5 and VEGFR2 around airways. Conversely, mimic 221 treated lungs had reduced airway branching, dilated airway tips and decreased Hoxb5 and VEGFR2 in mesenchyme. Anti-miR 130a treatment led to reduced airway branching with increased Hoxa5 and decreased VEGFR2 in the mesenchyme. Conversely, mimic 130a treated lungs had numerous finely arborized branches extending into central lung regions with diffusely localized Hoxa5 and increased VEGFR2 in the mesenchyme. Vascular morphology was analyzed by GSL-B4 (endothelial cell-specific lectin immunofluorescence. Observed changes in airway morphology following miR-221 inhibition and miR-130a enhancement were mirrored by changes in vascular plexus formation around the terminal airways. Mouse fetal lung endothelial cells (MFLM-91U were used to study microvascular cell behavior. Mimic 221 treatment resulted in reduced tube formation and cell migration, where as the reverse was observed with mimic 130a treatment. From these data, we conclude that miR-221 and miR-130a have opposing effects on airway and vascular morphogenesis of the developing lung.

    Recent observations of spawning lake trout Salvelinus namaycush near Drummond Island in northern Lake Huron indicate that lake trout use drumlins, landforms created in subglacial environments by the action of ice sheets, as a primary spawning habitat. From these observations, we generated a hypothesis that may in part explain locations chosen by lake trout for spawning. Most salmonines spawn in streams where they rely on streamflows to sort and clean sediments to create good spawning habitat. Flows sufficient to sort larger sediment sizes are generally lacking in lakes, but some glacial bedforms contain large pockets of sorted sediments that can provide the interstitial spaces necessary for lake trout egg incubation, particularly if these bedforms are situated such that lake currents can penetrate these sediments. We hypothesize that sediment inclusions from glacial scavenging and sediment sorting that occurred during the creation of bedforms such as drumlins, end moraines, and eskers create suitable conditions for lake trout egg incubation, particularly where these bedforms interact with lake currents to remove fine sediments. Further, these bedforms may provide high-quality lake trout spawning habitat at many locations in the Great Lakes and may be especially important along the southern edge of the range of the species. A better understanding of the role of glacially-derived bedforms in the creation of lake trout spawning habitat may help develop powerful predictors of lake trout spawning locations, provide insight into the evolution of unique spawning behaviors by lake trout, and aid in lake trout restoration in the Great Lakes.

    Treatment of post-traumatic stress disorder (PTSD) in refugees and asylum seekers resettled in high-income countries presents specific challenges. This systematic review examined the effectiveness of psychosocial interventions for this group. We searched the Cochrane Central Register of randomised trials, CINAHL, EMBASE, PILOTS, PsycINFO, PubMed and Web of Science up to July 2016. Studies included randomised and controlled clinical trials comparing psychosocial interventions with waiting list or treatment as usual in adult refugees and asylum seekers with PTSD resettled in high-income countries. PTSD symptoms post-intervention was the primary outcome. We computed standardized mean differences (SMD) with 95% confidence intervals (CI). This study is registered with PROSPERO: CRD42015027843. Twelve studies were included in the meta-analysis. Psychosocial interventions were effective in decreasing PTSD symptoms relative to control groups (SMD -1·03, 95% CI -1·55 to -0·51; number needed to treat 4·4; I2 86%; 95% CI 77 to 91). Narrative exposure therapy, a manualized short-term variant of cognitive behavioural therapy with a trauma focus, was the best-supported intervention (5 RCTs, 187 participants, SMD -0·78, 95% CI -1·18 to -0·38, I2 37%; 95% CI 0 to 77).

    Pregnant women seeking asylum in the United Kingdom appear particularly vulnerable, having complex health and social care needs and could benefit from a woman centred approach to midwifery care. This article is the second of three parts and reports on the findings from one objective of a wider doctorate study. It focuses on exploring midwifery students' perceptions of how to approach the care of pregnant women seeking asylum. Although the design of the study is explored in article one, in this context, the data was subject to critical discourse analysis to meet this objective. Key words and phrases were highlighted which appeared to reveal power and ideology implicit in the language used when discussing midwifery care of the pregnant woman seeking asylum. Dominant discourses were identified which appeared to influence the way in which care was approached and the possible sources of these discourses critically analysed. The findings suggest an underpinning ideology around following policies and guidelines to meet the physical needs of the woman at the expense of her other holistic needs. Despite learning to adopt a woman centred approach in theory, once in practice some students appear to be socialised into (re)producing these dominant medical and managerial discourses with "midwifery discourse" being marginalised. In addition, some students appeared to have difficulty understanding how to adopt a woman centred approach and the importance of considering the woman's context and its impact on care. These findings have implications for midwifery educators and this article identifies that the recent Nursing and Midwifery Council requirement for students to undertake a caseloading activity could provide the opportunity for them to adopt a consistent woman centred approach in practice, rejecting dominant medical and managerial discourses. However, these discourses appear to influence midwives caring for women more widely and will be difficult to challenge.

  20. The Impact of Direct Provision Accommodation for Asylum Seekers on Organisation and Delivery of Local Primary Care and Social Care Services: A Case Study

    Abstract Background Many western countries have policies of dispersal and direct provision accommodation (state-funded accommodation in an institutional centre) for asylum seekers. Most research focuses on its effect on the asylum seeking population. Little is known about the impact of direct provision accommodation on organisation and delivery of local primary care and social care services in the community. The aim of this research is to explore this issue. Methods In 2005 a direct provision accommodation centre was opened in a rural area in Ireland. A retrospective qualitative case study was designed comprising in-depth interviews with 37 relevant stakeholders. Thematic analysis following the principles of framework analysis was applied. Results There was lack of advance notification to primary care and social care professionals and the community about the new accommodation centre. This caused anxiety and stress among relevant stakeholders. There was insufficient time to plan and prepare appropriate primary care and social care for the residents, causing a significant strain on service delivery. There was lack of clarity about how primary care and social care needs of the incoming residents were to be addressed. Interdisciplinary support systems developed informally between healthcare professionals. This ensured that residents of the accommodation centre were appropriately cared for. Conclusions Direct provision accommodation impacts on the organisation and delivery of local primary care and social care services. There needs to be sufficient advance notification and inter-agency, inter-professional dialogue to manage this. Primary care and social care professionals working with asylum seekers should have access to training to enhance their skills for working in cross-cultural consultations.

    Treatment of post-traumatic stress disorder (PTSD) in refugees and asylum seekers resettled in high-income countries presents specific challenges. This systematic review examined the effectiveness of psychosocial interventions for this group. We searched the Cochrane Central Register of randomised trials, CINAHL, EMBASE, PILOTS, PsycINFO, PubMed and Web of Science up to July 2016. Studies included randomised and controlled clinical trials comparing psychosocial interventions with waiting list or treatment as usual in adult refugees and asylum seekers with PTSD resettled in high-income countries. PTSD symptoms post-intervention was the primary outcome. We computed standardized mean differences (SMD) with 95% confidence intervals (CI). This study is registered with PROSPERO: CRD42015027843. Twelve studies were included in the meta-analysis. Psychosocial interventions were effective in decreasing PTSD symptoms relative to control groups (SMD -1·03, 95% CI -1·55 to -0·51; number needed to treat 4·4; I2 86%; 95% CI 77 to 91). Narrative exposure therapy, a manualized short-term variant of cognitive behavioural therapy with a trauma focus, was the best-supported intervention (5 RCTs, 187 participants, SMD -0·78, 95% CI -1·18 to -0·38, I2 37%; 95% CI 0 to 77). Methodological quality of the included studies was limited. Overall, psychosocial interventions for asylum seekers and refugees with PTSD resettled in high-income countries were found to provide significant benefits in reducing PTSD symptoms. Yet, the number of studies is small and their methodological quality limited, so that more rigorous trials should be conducted in the future. PMID:28151992

    MicroRNAs (miRNAs) are small biological molecules that play an important role during the mechanisms of protein formation. Recent findings have demonstrated that they act as both positive and negative regulators of protein formation. Thus, the investigation of miRNAs, i.e., the determination of their level of expression, has developed a huge interest in the scientific community. One of the leading technologies for extracting miRNA data from biological samples is the miRNA Affymetrix platform. It provides the quantification of the level of expression of the miRNA in a sample, thus enabling the accumulation of data and allowing the determination of relationships among miRNA, genes, and diseases. Unfortunately, there is a lack of a comprehensive platform able to provide all the functions needed for the extraction of information from miRNA data. We here present miRNA-Analyzer, a complete software tool providing primary functionalities for miRNA data analysis. The current version of miRNA-Analyzer wraps the Affymetrix QCTool for the preprocessing of binary data files, and then provides feature selection (the filtering by species and by the associated p-value of preprocessed files). Finally, preprocessed and filtered data are analyzed by the Multiple Experiment Viewer (T-MEV) and Short Time Series Expression Miner (STEM) tools, which are also wrapped into miRNA-Analyzer, thus providing a unique environment for miRNA data analysis. The tool offers a plug-in interface so it is easily extensible by adding other algorithms as plug-ins. Users may download the tool freely for academic use at https://sites.google.com/site/mirnaanalyserproject/d. PMID:27983673

    Considerable Nanoarchaeota novelty and diversity were encountered in Yellowstone Lake, Yellowstone National Park (YNP), where sampling targeted lake floor hydrothermal vent fluids, streamers and sediments associated with these vents, and in planktonic photic zones in three different regions of the lake. Significant homonucleotide repeats (HR) were observed in pyrosequence reads and in near full-length Sanger sequences, averaging 112 HR per 1349 bp clone and could confound diversity estimates derived from pyrosequencing, resulting in false nucleotide insertions or deletions (indels). However, Sanger sequencing of two different sets of PCR clones (110 bp, 1349 bp) demonstrated that at least some of these indels are real. The majority of the Nanoarchaeota PCR amplicons were vent associated; however, curiously, one relatively small Nanoarchaeota OTU (71 pyrosequencing reads) was only found in photic zone water samples obtained from a region of the lake furthest removed from the hydrothermal regions of the lake. Extensive pyrosequencing failed to demonstrate the presence of an Ignicoccus lineage in this lake, suggesting the Nanoarchaeota in this environment are associated with novel Archaea hosts. Defined phylogroups based on near full-length PCR clones document the significant Nanoarchaeota 16S rRNA gene diversity in this lake and firmly establish a terrestrial clade distinct from the marine Nanoarcheota as well as from other geographical locations.

    Fry mortality which was first observed in the late 1960s in Great Lakes salmonines and in Baltic Sea salmon in 1974 has now been linked to thiamine deficiency (historically referred to as Early Mortality Syndrome, or EMS and M74, respectively). Over the past 14 years significant strides have been made in our understanding of this perplexing problem. It is now known that thiamine deficiency causes embryonic mortality in these salmonids. Both overt mortality and secondary effects of thiamine deficiency are observed in juvenile and adult animals. Collectively the morbidity and mortality (fry and adult mortality, secondary metabolic and behavior affects in juveniles and adult fish) are referred to as Thiamine Deficiency Complex (TDC). A workshop was held in Ann Arbor, MI on 6-7 November 2008 that brought together 38 federal, state, provincial, tribal and university scientists to share information, present data and discuss the latest observations on thiamine status of aquatic animals with thiamine deficiency and the causative agent, thiaminase. Twenty presentations (13 oral and 7 posters) detailed current knowledge. In Lake Huron, low alewife Alosa pseudoharengus abundance has persisted and egg thiamine concentrations in salmonines continue to increase, along with evidence of natural reproduction in lake trout Salvelinus namaycush. Lake Michigan Chinook salmon Oncorhynchus tshawytscha appear to have a lower thiamine requirement than other salmonids in the lake. Lake Ontario American eel Anguilla rostrata foraging on alewife have approximately one third the muscle thiamine compared to eels not feeding on alewife, suggesting that eels may be suffering from thiamine deficiency. Secondary effects of low thiamine exist in Great Lakes salmonines and should not be ignored. Thiaminase activity in dreissenid mussels is extremely high but a connection to TDC has not been made. Thiaminase in net plankton was found more consistently in lakes Michigan and Ontario than other lakes

    Between 25,000 and 30,000 playa lakes are in the playa lakes region of the southern high plains (Fig. 1). Most playas are in west Texas (about 20,000), and fewer, in New Mexico, Oklahoma, Kansas, and Colorado. The playa lakes region is one of the most intensively cultivated areas of North America. Dominant crops range from cotton in southern areas to cereal grains in the north. Therefore, most of the native short-grass prairie is gone, replaced by crops and, recently, grasses of the Conservation Reserve Program. Playas are the predominant wetlands and major wildlife habitat of the region.More than 115 bird species, including 20 species of waterfowl, and 10 mammal species have been documented in playas. Waterfowl nest in the area, producing up to 250,000 ducklings in wetter years. Dominant breeding and nesting species are mallards and blue-winged teals. During the very protracted breeding season, birds hatch from April through August. Several million shorebirds and waterfowl migrate through the area each spring and fall. More than 400,000 sandhill cranes migrate through and winter in the region, concentrating primarily on the larger saline lakes in the southern portion of the playa lakes region.The primary importance of the playa lakes region to waterfowl is as a wintering area. Wintering waterfowl populations in the playa lakes region range from 1 to 3 million birds, depending on fall precipitation patterns that determine the number of flooded playas. The most common wintering ducks are mallards, northern pintails, green-winged teals, and American wigeons. About 500,000 Canada geese and 100,000 lesser snow geese winter in the playa lakes region, and numbers of geese have increased annually since the early 1980’s. This chapter describes the physiography and ecology of playa lakes and their attributes that benefit waterfowl.

    Full Text Available OBJETIVO: verificar se as condições referentes à estrutura geral dos asilos, recursos humanos e rotinas diárias de alimentação em instituições asilares, podem potencializar alterações da dinâmica da deglutição em idosos. MÉTODOS: foi aplicado questionário aos dirigentes de cinco instituições asilares do município do Rio de Janeiro, no qual constavam perguntas em relação aos recursos materiais, humanos e rotina alimentar. RESULTADOS: o asilo do sistema privado foi o único a aproximar-se das condições ideais da estrutura geral para o atendimento do idoso. Em relação aos recursos humanos existentes, nenhum dos asilos possuía todos os profissionais exigidos pela portaria nº810/89. Em relação às rotinas diárias de alimentação, em uma das instituições pesquisadas, cuja maioria dos residentes não faziam uso de próteses dentárias, não havia restrição na consistência alimentar oferecida. Outro fator significativo diz respeito à negligência referente à higiene bucal, favorecendo a colonização de bactérias na cavidade oral, podendo agravar infecções pulmonares no caso de microaspirações. O fato dos idosos deitarem para dormir logo após o término das refeições, como ocorrido em três das instituições pesquisadas, tem grande importância na medida em que favorece a ocorrência de episódios de refluxo gastroesofágico. CONCLUSÃO: foram observados que em todas as instituições pesquisadas há fatores que podem potencializar um distúrbio de deglutição, como problemas em relação à estrutura geral e ou aos recursos humanos e ou relativos à rotina alimentar estabelecida.PURPOSE: to check if the conditions related to general structure, human resources and daily routine of feeding in asylums can increase the chances for an alteration in the deglutition process of the elderlies.

    Full Text Available Aim Recent research results in clinical psychology, health psychology and neurobiology underline the relationship between dissociative states, complex posttraumatic syndromes and borderline functioning [11]. Our study is meant to investigate the traumatic hypothesis of borderline functioning and to develop appropriate psychotherapeutic measures based on artistic mediations.Material and Methods.To estimate the effect of traumatic events, from the beginning of life up to recent stressors, linked to natural catastrophes, war, political persecution and migration, we undertook an integrated clinical and experimental study with a sample of 73 refugees and asylum seekers. In a second stage, those who suffered from PTSD or complex post-traumatic states were offered to attend arts psychotherapeutic sessions.To investigate the personality functioning at the structural level, we used a mixed quantitative and qualitative methodology, combining a semi-structured biographical interview, a projective test, i.e. the Sentences Completion Test, for which we developed a new manner of interpretation, and psychometric scales, i.e. the HADS and the Index of Wellbeing . Furthermore, we analysed the artistic production (pictures, stories written under musical induction with the help of rating scales constructed in the phenomenological and structural tradition.Results. With the help of non parametric multidimensional statistics, we extracted two profiles of personality functioning, linked either to repeated breaks, negligence and maltreatment from the beginningof life, or either to a recent external catastrophe, interrupting a continuous life course. Through the evaluation of the arts therapeutic sessions, we could note the first signs of resumption of the blocked process of subjectivation.Discussion.The results of the study support the traumatogenic hypothesis of borderline functioning, as well as current clinical considerations concerning the defensive role of

    Full Text Available Each month hundreds of men, women, and children flee Eritrea as a result of grave violations of human rights committed by the Eritrean government. Travelling across borders, an estimated 36,000 Eritreans have been smuggled to Israel over the past seven years. For 31 per cent of those interviewed for this research, their migration involved abduction and forced movement for extortion among other abuses. Migrants have been abducted in Eastern Sudan near the border with Eritrea and then sold to criminal gangs along the Sudan-Egypt border. The gangs forcibly hold the migrants captive in the Northern Sinai desert. Many who made the journey reported being held hostage and subjected to brutal treatment in Eastern Sudan and the Northern Sinai desert, including gang rape of men and women, whipping, and various other methods of physical and psychological torture. Although not a traditional trafficking scenario, this paper explores the phenomenon in relation to borders. Intricate trafficking networks have exploited refugee outflows from Eritrea, turning the area around the Sudanese side of the Eritrea-Sudan border into a breeding ground for abductions, aggravated smuggling, and trafficking. While crossing borders to claim asylum may facilitate some protection from abuses perpetrated by the Eritrean government, it has created a new set of challenges for Eritrean migrants who now must find protection and safety from kidnappers. While refugees must cross borders to find safety, those same borders create the circumstances for trafficking networks to operate. Unless the dynamics of those involved changes, human rights abuses such as extortion, torture and human trafficking in Eastern Sudan and Sinai are expected to continue.

    Full Text Available Abstract Background Ischemic postconditioning (IPost has aroused much attention since 2003 when it was firstly reported. The role of microRNAs (miRNAs or miRs in IPost has rarely been reported. The present study was undertaken to investigate whether miRNAs were involved in the protective effect of IPost against myocardial ischemia-reperfusion (IR injury and the probable mechanisms involved. Methods Thirty SD rats weighing 250-300 g were equally randomized to three groups: Control group, where the rats were treated with thoracotomy only; IR group, where the rats were treated with ischemia for 60 min and reperfusion for 180 min; and IPost group, where the rats were treated with 3 cycles of transient IR just before reperfusion. The extent of myocardial infarction, LDH and CK activities were measured immediately after treatment. Myocardial apoptosis was detected by TUNEL assay. The myocardial tissue was collected after IR or IPost stimulation to evaluate the miRNAs expression level by miRNA-microarray and quantitative real-time RT-PCR. Real-time PCR was conducted to identify changes in mRNA expression of apoptosis-related genes such as Bcl-2, Bax and Caspase-9 (CASP9, and Western blot was used to compare the protein expression level of CASP9 in the three groups. The miRNA mimics and anti-miRNA oligonucleotides (AMO were transferred into the cultured neonatal cardiomyocytes and myocardium before they were treated with IR. The effect of miRNAs on apoptosis was determined by flow cytometry and TUNEL assay. CASP9, as one of the candidate target of miR-133a, was compared during IR after the miR-133a mimic or AMO-133a was transferred into the myocardium. Results IPost reduced the IR-induced infarct size of the left ventricle, and decreased CK and LDH levels. TUNEL assay showed that myocardial apoptosis was attenuated by IPost compared with IR. MiRNA-microarray and RT-PCR showed that myocardial-specific miR-1 and miR-133a were down-regulated by IR, and up

    Declining lake levels (Aral Sea syndrome) can be caused by changes in climate, increased water use or changed regulation patterns. This paper introduces a novel lake geometry index (LGI) to quantify lake hydrological characteristics. The index was developed using a large representative dataset of lake hypsographic characteristics from 152 lakes and man-made reservoirs. Using the LGI index, lakes can be classified into five groups: groups 1-4 when LGI is 0.5-2.5, 2.5-4.5, 4.5-6.5 and 6.5-8.5, respectively, and group 5 when LGI is >8.5. Naturally shallow and vast lakes and wetlands fall into the first group and deep man-made reservoirs in narrow valleys are in group 5. The response of three different lake systems (LGI 0.75, 2.75 and 6.5) to different water flow scenarios was then simulated using the water balance equation. From this, the index 'potential lake area' (Apot) was developed to show lake responses to changed hydro-climatological conditions. Apot and LGI can be used to classify lakes into open or closed systems. Simulations showed that lakes with low LGI have a shorter response time to flow and climate changes. As a result, the impact of water balance restoration is faster for lakes with low LGI than for lakes with high LGI. The latter are also more vulnerable to climate variation and change.

  8. Haplotype distribution and evolutionary pattern of miR-17 and miR-124 families based on population analysis.

    Directory of Open Access Journals (Sweden)

    Li Guo

    Full Text Available BACKGROUND: MicroRNAs (miRNAs are small, endogenously expressed non-coding RNAs that regulate mRNAs post-transcriptionally. Previous studies have explored miRNA evolutionary trend, but evolutionary history and pattern in the miRNA world are still not fully clear. In the paper, we intended to analyze miRNA haplotype distribution and evolutionary network by analyzing miRNA sequences of miR-17 and miR-124 families across animal species as special populations. PRINCIPAL FINDINGS: 31 haplotypes were detected in miR-17 family while only 9 haplotypes were defined in miR-124 family. The complex miR-17 family was mainly distributed in vertebrates, but miR-124 was shared by more animal species from Caenorhabditis to Homo and had a wide distribution spectrum. Some haplotypes of the two miRNA families appeared discontinuous distributions across animals. Compared with a simple phylogenetic network in miR-124 family, miR-17 family indicated a complex network with some median vectors that might be lost ancestral or potential miRNA haplotypes. By analyzing different miRNAs across 12 animal species, we found these small RNAs showed different haplotype diversities, haplotype distributions and phylogenetic networks. CONCLUSIONS: Different miRNAs had quite different haplotype distributions and evolutionary patterns. Discontinuous distributions of miRNAs and median vectors in phylogenetic networks implied more members in the miRNA world. miRNA may be an excellent phylogenetic marker to discover its evolutionary history and pattern across the animal kingdom.

    The purpose of this study was to identify and validate circulating microRNAs (miRNAs) in human plasma for use as breast cancer (BC) biomarkers and to analyze their relationship to clinicopathologic features and its preliminary biological function.Genome-wide expression profiling of miRNAs in BC was investigated by microarray analysis.nmiR-155 was up-regulated greater than two-fold in BC compared with Normal Adjacent Tissue (NAT),whereas let-7b,miR-381,miR-10b,miR-125a-Sp,miR-335,miR-205 and miR-145 were down-regulated greater than two-fold.Our hypothesis was that circulating miRNAs are also present and differentially expressed in the serum of BC patients compared to controls.Using real-time PCR (RT-PCR),we analyzed miR-205 and miR-155 in archived serum from 30 participants,20 with breast cancer and 10 healthy people.miR-205 was down-regulated in BC patient serum while miR-155 was up-regulated.Furthermore,we analyzed the relationship between the expression levels of these two miRNAs and the clinicopathologic parameters of BC patients.High expression of miR155 was associated with clinical stage,molecular type,Ki-67 and p53 in BC patients (P<0.05).By contrast,we found no significant correlation between miR-205 and BC patient clinicopathologic parameters.Functional analysis showed that ectopic expression of miR-205 significantly inhibits cell proliferation and promotes apoptosis.miR-205 was down-regulated and miR-155 was up-regulated in BC patient serum.miR-155 was positive correlated with clinical stage and ki-67 and negatively correlated with p53 status.

    Lake Tahoe, an iconic ultra-oligotrophic lake in the central Sierra Nevada, has been studied intensively since 1968, with the goal of understanding and ultimately controlling its eutrophication and loss of clarity. Research on the lake has included a) periodic profiles of primary productivity, nutrients, temperature, and plankton; b) Secchi depth; c) nutrient limitation experiments; d) analysis of sediment cores; e) radiocarbon dating of underwater in-place tree stumps; g) analysis of long-term temperature trends. Work in its watershed has included a) monitoring of stream discharge, sediment and nutrients at up to 20 stream gaging stations; b) monitoring of urban runoff water quality at selected sites; c) development of a GIS data base, including soils, vegetation, and land use. Based on these studies, we know that a) primary productivity in the lake is limited by phosphorus, and continues to increase; b) the loss of clarity continues, but at a declining rate; c) the lake has been warming since 1970, and its resistance to deep mixing is increasing; d) historically the lake level drops below the outlet elevation about one year in seven; e) 6300 to 4300 yrs BP lake level was below the present outlet elevation long enough for large trees to grow; f) the date of the peak snowmelt runoff is shifting toward earlier dates; g) after accounting for annual runoff, loads of nutrients and suspended sediment have declined significantly in some basin streams since 1980. Downscaled outputs from GCM climatic models have recently been used to drive hydrologic models and a lake clarity model, projecting future trends in the lake and watersheds. Results show a) the temperature and thermal stability will likely continue to increase, with deep mixing shutting down in the latter half of this century; b) the lake may drop below the outlet for an extended period beginning about 2085; c) the annual snowpack will continue to decline, with earlier snowmelt and shift from snowfall to rain; d

    PURPOSE: Therapeutic decisions in breast cancer are increasingly guided by prognostic and predictive biomarkers. Non-protein-coding microRNAs (miRNAs) have recently been found to be deregulated in breast cancers and, in addition, to be correlated with several clinico-pathological features. One...... of the most consistently up-regulated miRNAs is miR-21. Here, we specifically searched for differentially expressed miRNAs in high-risk breast cancer patients as compared to low-risk breast cancer patients. In the same patients, we also compared miR-21 expression with the expression of its presumed target...... PTEN. METHODS: Both microarray and RT-qPCR techniques were used to assess miRNA expression levels in lymph node-positive and -negative human invasive ductal carcinoma tissues. Simultaneously, PTEN protein expression levels were assessed using immunohistochemistry. RESULTS: miR-486-5p and miR-139-5p...

    We studied miRNA profiles in 4419 human samples (3312 neoplastic, 1107 nonmalignant), corresponding to 50 normal tissues and 51 cancer types. The complexity of our database enabled us to perform a detailed analysis of microRNA (miRNA) activities. We inferred genetic networks from miRNA expression in normal tissues and cancer. We also built, for the first time, specialized miRNA networks for solid tumors and leukemias. Nonmalignant tissues and cancer networks displayed a change in hubs, the most connected miRNAs. hsa-miR-103/106 were downgraded in cancer, whereas hsa-miR-30 became most prominent. Cancer networks appeared as built from disjointed subnetworks, as opposed to normal tissues. A comparison of these nets allowed us to identify key miRNA cliques in cancer. We also investigated miRNA copy number alterations in 744 cancer samples, at a resolution of 150 kb. Members of miRNA families should be similarly deleted or amplified, since they repress the same cellular targets and are thus expected to have similar impacts on oncogenesis. We correctly identified hsa-miR-17/92 family as amplified and the hsa-miR-143/145 cluster as deleted. Other miRNAs, such as hsa-miR-30 and hsa-miR-204, were found to be physically altered at the DNA copy number level as well. By combining differential expression, genetic networks, and DNA copy number alterations, we confirmed, or discovered, miRNAs with comprehensive roles in cancer. Finally, we experimentally validated the miRNA network with acute lymphocytic leukemia originated in Mir155 transgenic mice. Most of miRNAs deregulated in these transgenic mice were located close to hsa-miR-155 in the cancer network. PMID:20439436

  15. miR-29b, miR-205 and miR-221 enhance chemosensitivity to gemcitabine in HuH28 human cholangiocarcinoma cells.

    Kinya Okamoto

    Full Text Available BACKGROUND AND AIMS: Cholangiocarcinoma (CCA is highly resistant to chemotherapy, including gemcitabine (Gem treatment. MicroRNAs (miRNAs are endogenous, non-coding, short RNAs that can regulate multiple genes expression. Some miRNAs play important roles in the chemosensitivity of tumors. Here, we examined the relationship between miRNA expression and the sensitivity of CCA cells to Gem. METHODS: Microarray analysis was used to determine the miRNA expression profiles of two CCA cell lines, HuH28 and HuCCT1. To determine the effect of candidate miRNAs on Gem sensitivity, expression of each candidate miRNA was modified via either transfection of a miRNA mimic or transfection of an anti-oligonucleotide. Ontology-based programs were used to identify potential target genes of candidate miRNAs that were confirmed to affect the Gem sensitivity of CCA cells. RESULTS: HuCCT1 cells were more sensitive to Gem than were HuH28 cells, and 18 miRNAs were differentially expressed whose ratios over ± 2log2 between HuH28 and HuCCT1. Among these 18 miRNAs, ectopic overexpression of each of three downregulated miRNAs in HuH28 (miR-29b, miR-205, miR-221 restored Gem sensitivity to HuH28. Suppression of one upregulated miRNA in HuH28, miR-125a-5p, inhibited HuH28 cell proliferation independently to Gem treatment. Selective siRNA-mediated downregulation of either of two software-predicted targets, PIK3R1 (target of miR-29b and miR-221 or MMP-2 (target of miR-29b, also conferred Gem sensitivity to HuH28. CONCLUSIONS: miRNA expression profiling was used to identify key miRNAs that regulate Gem sensitivity in CCA cells, and software that predicts miRNA targets was used to identify promising target genes for anti-tumor therapies.

  16. miReader: Discovering Novel miRNAs in Species without Sequenced Genome.

    Ashwani Jha

    Full Text Available Along with computational approaches, NGS led technologies have caused a major impact upon the discoveries made in the area of miRNA biology, including novel miRNAs identification. However, to this date all microRNA discovery tools compulsorily depend upon the availability of reference or genomic sequences. Here, for the first time a novel approach, miReader, has been introduced which could discover novel miRNAs without any dependence upon genomic/reference sequences. The approach used NGS read data to build highly accurate miRNA models, molded through a Multi-boosting algorithm with Best-First Tree as its base classifier. It was comprehensively tested over large amount of experimental data from wide range of species including human, plants, nematode, zebrafish and fruit fly, performing consistently with >90% accuracy. Using the same tool over Illumina read data for Miscanthus, a plant whose genome is not sequenced; the study reported 21 novel mature miRNA duplex candidates. Considering the fact that miRNA discovery requires handling of high throughput data, the entire approach has been implemented in a standalone parallel architecture. This work is expected to cause a positive impact over the area of miRNA discovery in majority of species, where genomic sequence availability would not be a compulsion any more.

  17. Resilience and Restoration of Lakes

    Directory of Open Access Journals (Sweden)

    Kathryn L. Cottingham

    1997-06-01

    Full Text Available Lake water quality and ecosystem services are normally maintained by several feedbacks. Among these are nutrient retention and humic production by wetlands, nutrient retention and woody habitat production by riparian forests, food web structures that cha nnel phosphorus to consumers rather than phytoplankton, and biogeochemical mechanisms that inhibit phosphorus recycling from sediments. In degraded lakes, these resilience mechanisms are replaced by new ones that connect lakes to larger, regional economi c and social systems. New controls that maintain degraded lakes include runoff from agricultural and urban areas, absence of wetlands and riparian forests, and changes in lake food webs and biogeochemistry that channel phosphorus to blooms of nuisance al gae. Economic analyses show that degraded lakes are significantly less valuable than normal lakes. Because of this difference in value, the economic benefits of restoring lakes could be used to create incentives for lake restoration.

    Full Text Available Male fertility requires the continuous production of high quality motile spermatozoa in abundance. Alterations in all three metrics cause oligoasthenoteratozoospermia, the leading cause of human sub/infertility. Post-mitotic spermatogenesis inclusive of several meiotic stages and spermiogenesis (terminal spermatozoa differentiation are transcriptionally inert, indicating the potential importance for the post-transcriptional microRNA (miRNA gene-silencing pathway therein. We found the expression of miRNA generating enzyme Dicer within spermatogenesis peaks in meiosis with critical functions in spermatogenesis. In an expression screen we identified two miRNA loci of the miR-34 family (miR-34b/c and miR-449 that are specifically and highly expressed in post-mitotic male germ cells. A reduction in several miRNAs inclusive of miR-34b/c in spermatozoa has been causally associated with reduced fertility in humans. We found that deletion of both miR34b/c and miR-449 loci resulted in oligoasthenoteratozoospermia in mice. MiR-34bc/449-deficiency impairs both meiosis and the final stages of spermatozoa maturation. Analysis of miR-34bc-/-;449-/- pachytene spermatocytes revealed a small cohort of genes deregulated that were highly enriched for miR-34 family target genes. Our results identify the miR-34 family as the first functionally important miRNAs for spermatogenesis whose deregulation is causal to oligoasthenoteratozoospermia and infertility.

    2009-01-01

    Full Text Available Based on a research project with migrants from Iran this paper focuses on the influence of a strictly regulated German asylum life situation on autobiographical telling in research contexts. Regardless of the specific research topic the interview situation and the relationship between interviewer and interviewee always influence shape, form and fashion of the biographical narration. As a result of the strict regimentation of the asylum procedures and their far-reaching impact on biographies in the "total refugee space," an intensification of the hierarchical structure in the interview situation can be observed. Considering the empirical results this paper calls for a reflexive biographical research. This approach has to analyze the power relations in the transnational space and their consequences on the research process. It also has to recognize that researchers and interviewees are not only confined to their culture differences, but that the setting comprises all intersectional localizations, which are defined by social and economic status, nationality, gender, sexuality etc. URN: urn:nbn:de:0114-fqs0901393

    ABSTRACT Despite the search for new therapeutic strategies for gastric cancer (GC), there is much evidence of progression due to resistance to chemotherapy. Multidrug resistance (MDR) is the ability of cancer cells to survive after exposure to chemotherapeutic agents. The involvement of miRNAs in the development of MDR has been well described but miRNAs able to modulate the sensitivity to chemotherapy by regulating hypoxia signaling pathways have not yet been fully addressed in GC. Our aim was to analyze miR-20b, miR-27a and miR-181a expression with respect to (epirubicin/oxaliplatin/capecitabine (EOX)) chemotherapy regimen in a set of GC patients, in order to investigate whether miRNAs deregulation may influence GC MDR also via hypoxia signaling modulation. Cancer biopsy were obtained from 21 untreated HER2 negative advanced GC patients, retrospectively analyzed. All patients received a first-line chemotherapy (EOX) regimen. MirWalk database was used to identify miR-27a, miR-181a and miR-20b target genes. The expression of miRNAs and of HIPK2, HIF1A and MDR1 genes were detected by real-time PCR. HIPK2 localization was assessed by immunohistochemistry. Our data showed the down-regulation of miR-20b, miR-27a, miR-181a concomitantly to higher levels of MDR1, HIF1A and HIPK2 genes in GC patients with a progressive disease respect to those with a disease control rate. Moreover, immunohistochemistry assay highlighted a higher cytoplasmic HIPK2 staining, suggesting a different role for it. We showed that aberrant expression of miR-20b, miR27a and miR-181a was associated with chemotherapeutic response in GC through HIF1A, MDR1 and HIPK2 genes modulation, suggesting a possible novel therapeutic strategy.

    Full Text Available Johan Turi (1854–1936, Nils Nilsson Skum (1872–1951 and John Savio (1902–1938 were among the first Sámi visual artists. The production of their art work occurred between the 1910s and the early 1950s. Sámi aesthetics had its basis in folklore, i.e., handicraft or duodji, which did not follow the principle of art for art’s sake but combined beauty and practicality. Art was part of community life. Not until the 1970s was the word daidda, which is Finnish in origin and which means “art”, adopted into the Sámi language. Turi and Skum became famous through their books. They drew and wrote in order to pass the traditional knowledge of their people on to succeeding generations. They also wanted to introduce Sámi life and culture to non-Sámi people. One typical feature of their work is that they depicted Sáminess in a realistic way and sought to strengthen and preserve the Sámi identity through their art. In Turi and Skum’s work, both the documentation of community life and their own personal expression were strongly present and equally important; for this reason their pictures and texts have both practical and aesthetic dimensions. They did not attend school and were self-taught artists. The third pioneer of Sámi visual arts was John Savio, who, unlike the other two, attended secondary school and studied visual arts both independently and under the guidance of a mentor. He expressively combined Western ways of depiction with Sámi subjects. My article examines what made these early Sámi artists change over from Sámi handicraft, duodji, to Western visual arts, how they used Western pictorial conventions in dealing with their Sámi subjects, and the significance of their art for Sámi identity and culture. They lived and worked under cross pressure: the first few decades of the 20th century were characterized by racial theories that denigrated Sámi people, and the period following World War II was marked by demands for

    MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression via posttranscriptional inhibition of protein synthesis. They play a vital role in tumorigenesis. To characterize the diagnostic potential of miRNAs in prostate cancer, a leading cause of cancer mortality, we performed.......6% with an area under the receiver–operator characteristic curve of 0.810. Our data extend the knowledge about the deregulation of miRNAs in prostate cancer. The differential expression of several miRNAs is highly consistent using independent cohorts of tumor samples, different tissue preservation methods...... and different experimental methods. Our results indicate that combinations of miRNAs are promising biomarkers for the diagnosis of prostate cancer....

  5. Is Lake Chabot Eutrophic?

    Science.gov (United States)

    Introduction/Abstract: Lake Chabot is an integral part of the East Bay watershed that provides habitats for animals and recreation for humans year-round. Lake Chabot has been in danger of eutrophication due to excessive dumping of phosphorous and nitrogen into the water from the fertilizers of nearby golf courses and neighboring houses. If the lake turned out to be eutrophified, it could seriously impact what is currently the standby emergency water supply for many Castro Valley residents. Eutrophication is the excessive richness of nutrients such as nitrogen and phosphorus in a lake, usually as a result of runoff. This buildup of nutrients causes algal blooms. The algae uses up most of the oxygen in the water, and when it dies, it causes the lake to hypoxify. The fish in the lake can't breathe, and consequently suffocate. Other oxygen-dependant aquatic creatures die off as well. Needless to say, the eutrophication of a lake is bad news for the wildlife that lives in or around it. The level of eutrophication in our area in Northern California tends to increase during the late spring/early summer months, so our crew went out and took samples of Lake Chabot on June 2. We focused on the area of the lake where the water enters, known on the map as Honker Bay. We also took readings a ways down in deeper water for comparison's sake. Visually, the lake looked in bad shape. The water was a murky green that glimmered with particulate matter that swirled around the boat as we went by. In the Honker Bay region where we focused our testing, there were reeds bathed in algae that coated the surface of the lake in thick, swirling patterns. Surprisingly enough, however, our test results didn't reveal any extreme levels of phosphorous or nitrogen. They were slightly higher than usual, but not by any significant amount. The levels we found were high enough to stimulate plant and algae growth and promote eutrophication, but not enough to do any severe damage. After a briefing with a

    This is the first in a two-part series of papers examining mental health issues for refugees and asylum seekers. Beginning with the suicide of an asylum seeker in Scotland, the paper emphasizes mental health issues for adult and child asylum seekers, stress and memory, suicide, self-harm, risk and protective factors, compulsory health treatments and the prevention of mental illness. It sets the scene for the second paper by drawing implications for nursing practice in the community. Although most literature on refugee and asylum seeker mental health exists outside of nursing scholarship, a majority of the issues reviewed in this paper are mutual challenges for all in the health and helping professions. Nurses interested in refugee and migration issues face two intertwined challenges: that of how to assist migrants with their diverse mental health needs and how, at the same time, to contribute to a society that can promote mental health for all by taking on both the difficulties and opportunities posed by cultural diversity.

    Regulation of the cell cycle is complex but critical for proper development, reproduction and stress resistance. To survive unfavourable environmental conditions, the crustacean Artemia produces diapause embryos whose metabolism is maintained at extremely low levels. In the present study, the expression profiles of miRNAs during Artemia diapause entry and termination were characterized using high-throughput sequencing. A total of 13 unclassified miRNAs and 370 miRNAs belonging to 87 families were identified; among them, 107 were differentially expressed during diapause entry and termination. We focused on the roles of two of these miRNAs, miR-100 and miR-34, in regulating cell cycle progression; during the various stages of diapause entry, these miRNAs displayed opposing patterns of expression. A functional analysis revealed that miR-100 and miR-34 regulate the cell cycle during diapause entry by targeting polo-like kinase 1 (PLK1), leading to activation of the mitogen-activated protein kinase kinase-extracellular signal-regulated kinase-ribosomal S6 kinase 2 (MEK-ERK-RSK2) pathway and cyclin K, leading to suppression of RNA polymerase II (RNAP II) activity respectively. The findings presented in the present study provide insights into the functions of miR-100 and miR-34 and suggest that the expression profiles of miRNAs in Artemia can be used to characterize their functions in cell cycle regulation.

  11. Discovery of miRNAs and Their Corresponding miRNA Genes in Atlantic Cod (Gadus morhua: Use of Stable miRNAs as Reference Genes Reveals Subgroups of miRNAs That Are Highly Expressed in Particular Organs.

    Full Text Available Atlantic cod (Gadus morhua is among the economically most important species in the northern Atlantic Ocean and a model species for studying development of the immune system in vertebrates. MicroRNAs (miRNAs are an abundant class of small RNA molecules that regulate fundamental biological processes at the post-transcriptional level. Detailed knowledge about a species miRNA repertoire is necessary to study how the miRNA transcriptome modulate gene expression. We have therefore discovered and characterized mature miRNAs and their corresponding miRNA genes in Atlantic cod. We have also performed a validation study to identify suitable reference genes for RT-qPCR analysis of miRNA expression in Atlantic cod. Finally, we utilized the newly characterized miRNA repertoire and the dedicated RT-qPCR method to reveal miRNAs that are highly expressed in certain organs.The discovery analysis revealed 490 mature miRNAs (401 unique sequences along with precursor sequences and genomic location of the miRNA genes. Twenty six of these were novel miRNA genes. Validation studies ranked gmo-miR-17-1-5p or the two-gene combination gmo-miR25-3p and gmo-miR210-5p as most suitable qPCR reference genes. Analysis by RT-qPCR revealed 45 miRNAs with significantly higher expression in tissues from one or a few organs. Comparisons to other vertebrates indicate that some of these miRNAs may regulate processes like growth, lipid metabolism, immune response to microbial infections and scar damage repair. Three teleost-specific and three novel Atlantic cod miRNAs were among the differentially expressed miRNAs.The number of known mature miRNAs was considerably increased by our identification of miRNAs and miRNA genes in Atlantic cod. This will benefit further functional studies of miRNA expression using deep sequencing methods. The validation study showed that stable miRNAs are suitable reference genes for RT-qPCR analysis of miRNA expression. Applying RT-qPCR we have identified

  12. MI Gap Clearing Kicker Magnet Design Review

    Energy Technology Data Exchange (ETDEWEB)

    Jensen, Chris; /Fermilab

    2008-10-01

    The kicker system requirements were originally conceived for the NOvA project. NOvA is a neutrino experiment located in Minnesota. To achieve the desired neutrino flux several upgrades are required to the accelerator complex. The Recycler will be used as a proton pre-injector for the Main Injector (MI). As the Recycler is the same size as the MI, it is possible to do a single turn fill ({approx}11 {micro}sec), minimizing the proton injection time in the MI cycle and maximizing the protons on target. The Recycler can then be filled with beam while the MI is ramping to extract beam to the target. To do this requires two new transfer lines. The existing Recycler injection line was designed for 10{pi} pbar beams, not the 20{pi} proton beams we anticipate from the Booster. The existing Recycler extraction line allows for proton injection through the MI, while we want direct injection from the Booster. These two lines will be decommissioned. The new injection line from the MI8 line into the Recycler will start at 848 and end with injection kickers at RR104. The new extraction line in the RR30 straight section will start with a new extraction kicker at RR232 and end with new MI injection kickers at MI308. Finally, to reduce beam loss activation in the enclosure, a new gap clearing kicker will be used to extract uncaptured beam created during the slip stack injection process down the existing dump line. It was suggested that the MI could benefit from this type of system immediately. This led to the early installation of the gap clearing system in the MI, followed by moving the system to Recycler during NOvA. The specifications also changed during this process. Initially the rise and fall time requirements were 38 ns and the field stability was {+-}1%. The 38 ns is based on having a gap of 2 RF buckets between injections. (There are 84 RF buckets that can be filled from the Booster for each injection, but 82 would be filled with beam. MI and Recycler contain 588 RF buckets

    Full Text Available Long noncoding RNAs (lncRNAs are emerging as new players in gene regulation, but whether lncRNAs operate in the processing of miRNA primary transcript is unclear. Also, whether lncRNAs are involved in the regulation of the mitochondrial network remains to be elucidated. Here, we report that a long noncoding RNA, named mitochondrial dynamic related lncRNA (MDRL, affects the processing of miR-484 primary transcript in nucleus and regulates the mitochondrial network by targeting miR-361 and miR-484. The results showed that miR-361 that predominantly located in nucleus can directly bind to primary transcript of miR-484 (pri-miR-484 and prevent its processing by Drosha into pre-miR-484. miR-361 is able to regulate mitochondrial fission and apoptosis by regulating miR-484 levels. In exploring the underlying molecular mechanism by which miR-361 is regulated, we identified MDRL and demonstrated that it could directly bind to miR-361 and downregulate its expression levels, which promotes the processing of pri-miR-484. MDRL inhibits mitochondrial fission and apoptosis by downregulating miR-361, which in turn relieves inhibition of miR-484 processing by miR-361. Our present study reveals a novel regulating model of mitochondrial fission program which is composed of MDRL, miR-361 and miR-484. Our work not only expands the function of the lncRNA pathway in gene regulation but also establishes a new mechanism for controlling miRNA expression.

    Concentrations, stable chlorine and oxygen isotopic compositions, and 36Cl abundances of perchlorate were investigated in the five Laurentian Great Lakes. Samples were collected during monitoring cruises in 2007 and 2008 of the U.S. EPA's RV Lake Guardian and in 2010 at the water supply intake of Marquette, MI on the southern shore of Lake Superior. Concentrations of perchlorate were measured by IC/MS/MS at 24 locations, including one or two depth profiles in each lake. Mean concentrations (μg/L) are: Superior, 0.06 × 0.01; Michigan, 0.10 × 0.01; Huron, 0.11 × 0.01; Erie, 0.08 × 0.01, and Ontario, 0.09 × 0.01. Concentration vs. depth is nearly constant in each lake, indicating well-mixed conditions. Perchlorate was extracted from near-surface water by passing 15,000 to 80,000 L of water through 1-L cartridges containing Purolite A530E bifunctional anion-exchange resin. In the laboratory, perchlorate was eluted from the resin, purified, and precipitated as a >99% pure crystalline phase. Milligram amounts were recovered from each lake. Chlorine and oxygen isotopic analyses were performed at Caltech using the Cameca 7f-GEO SIMS instrument, following validation of the SIMS method with analyses of USGS-37 and USGS-38 isotopic reference materials. Results indicate a relatively narrow range in δ37Cl values (+2.9 to +3.9 ‰) and a wider range in δ18O values (-4.0 to +4.1 ‰), with a general geographic trend of increasing δ18O from west to east. Oxygen-17 was measured at UIC using dual-inlet IRMS of O2 produced by decomposition of KClO4. Great Lakes perchlorate has mass-independent oxygen isotopic variations with positive Δ17O values (+1.6 ‰ to +2.7 ‰) divided into two distinct groups: Lake Superior (+2.7 ‰) and the other four lakes (~ +1.7 ‰). The isotopic data indicate that perchlorate is dominantly of natural origin, having stable isotopic compositions resembling those of perchlorate from pre-industrial groundwaters in the western USA.

    MicroRNAs (miRNAs) are small non-coding RNAs composed of 18-25 nucleotides that can post-transcriptionally regulate gene expression and have key regulatory roles in cancer, acting as both oncogenes and tumor suppressors. About 1000 genes in humans encode miRNAs, which account for approximately 3% of the human genome, and up to 30% of human protein coding genes may be regulated by miRNAs. The objective of this article is to evaluate the expression profile of four miRNAs previously implicated in triple negative breast cancer: miR-10b, miR-26a, miR-146a and miR-153, and to determine their possible interaction in triple negative and non triple negative breast cancer based on clinical outcome and the expression of BRCA1. 24 triple-negative and 13 non triple negative breast cancer cases, were studied by q-RT-PCR and immunohistochemistry to determine the expression of the four studied miRNAs and the BRCA1 protein, respectively. We observed that the BRCA1 protein was absent in 62.5% of the triple negative cases. Besides, the miR-146a and miR-26a were over expressed in triple negative breast cancer. These two miRNAs, miR-10b and miR-153 were significantly associated to lymph node metastases occurrence in triple negative breast carcinoma. All the analyzed microRNAs were not associated with the expression of BRCA1 in our conditions. Our work provides evidence that miR-146a, miR-26a, miR-10b and miR-153 could be defined as biomarkers in triple negative breast cancer to predict lymph node metastases (LNM).

    The Mid-Lake Reef Complex (MLRC), a large area of deep (> 40 m) reefs, was a major site where indigenous lake trout (Salvelinus namaycush) in Lake Michigan aggregated during spawning. As part of an effort to restore Lake Michigan's lake trout, which were extirpated in the 1950s, yearling lake trout have been released over the MLRC since the mid-1980s and fall gill net censuses began to show large numbers of lake trout in spawning condition beginning about 1999. We report the first evidence of viable egg deposition and successful lake trout fry production at these deep reefs. Because the area's existing bathymetry and habitat were too poorly known for a priori selection of sampling sites, we used hydroacoustics to locate concentrations of large fish in the fall; fish were congregating around slopes and ridges. Subsequent observations via unmanned submersible confirmed the large fish to be lake trout. Our technological objectives were driven by biological objectives of locating where lake trout spawn, where lake trout fry were produced, and what fishes ate lake trout eggs and fry. The unmanned submersibles were equipped with a suction sampler and electroshocker to sample eggs deposited on the reef, draw out and occasionally catch emergent fry, and collect egg predators (slimy sculpin Cottus cognatus). We observed slimy sculpin to eat unusually high numbers of lake trout eggs. Our qualitative approaches are a first step toward quantitative assessments of the importance of lake trout spawning on the MLRC.

    miRNAs are non-coding RNA molecules typically 18-22 nucleotides long that can suppress the expression of their target genes. Several laboratories have attempted to identify miRNAs from the pig that are involved in Salmonella infection. These bioinformatics strategies using the newly available genomic sequence are generally successful. Here, we report an in silico identification of miRNAs in pig focusing on the Salmonella infection pathway, and further investigated the differential expression of those miRNAs by quantitative real-time PCR during pre- and post-natal stage of Salmonella inoculation from the peripheral blood of commercially breed pigs. We identified 29 miRNAs that have predicted targets in the Salmonella infection pathway and nine of them were not yet described in pig. In addition, the expression of nine selected miRNAs was validated in the peripheral blood by northern blotting. Through expression analyses, differences were found between pre- and post-natal stages of Salmonella inoculation for miR-221, miR-125b and miR-27b-all of them were suppressed 2 days after Salmonella inoculation. The predicted targets of those three miRNAs were validated by luciferase reporter assays. We show that FOS is a direct target of miR-221, miR-125b can suppress MAPK14, and miR-27b can target IFNG. These findings will be helpful in understanding the function and processing of these miRNAs in Salmonella infection. The miRNA differentially expressed in the peripheral blood of commercial breed pigs suggest that it can be used as genetic markers for salmonella infection resistance in pigs.

    We present a human miRNA tissue atlas by determining the abundance of 1997 miRNAs in 61 tissue biopsies of different organs from two individuals collected post-mortem. One thousand three hundred sixty-four miRNAs were discovered in at least one tissue, 143 were present in each tissue. To define the distribution of miRNAs, we utilized a tissue specificity index (TSI). The majority of miRNAs (82.9%) fell in a middle TSI range i.e. were neither specific for single tissues (TSI > 0.85) nor housekeeping miRNAs (TSI saarland.de/tissueatlas).

    Evidence suggests neuroprotective effects of fluoxetine, a selective serotonin reuptake inhibitor (SSRI), on the developed neurons in the adult brain. In contrast, the drug may be deleterious to immature or undifferentiated neural cells, although the mechanism is unclear. Recent investigations have suggested that microRNAs (miRNA) may be critical for effectiveness of psychotropic drugs including SSRI. We investigated whether fluoxetine could modulate expressions of neurologically relevant miRNAs in two neuroblastoma SK-N-SH and SH-SY5Y cell lines. Initial screening results revealed that three (miR-489, miR-572 and miR-663a) and four (miR-320a, miR-489, miR-572 and miR-663a) miRNAs were up-regulated in SK-N-SH cells and SH-SY5Y cells, respectively, after 24 hours treatment of fluoxetine (1–25 μM). Cell viability was reduced according to the dose of fluoxetine. The upregulation of miR-572 and miR-663a was consistent in both the SH-SY5Y and SK-N-SH cells, confirmed by a larger scale culture condition. Our data is the first in vitro evidence that fluoxetine could increase the expression of miRNAs in undifferentiated neural cells, and that putative target genes of those miRNAs have been shown to be involved in fundamental neurodevelopmental processes.

    Full Text Available Aberrant miRNA expression is well recognized as a cancer hallmark, nevertheless miRNA function and expression does not always correlate in patients tissues and cell lines studies. In addition to this issue, miRNA strand usage conduces to increased cell signaling pathways modulation diversifying cellular processes regulation. In cervical cancer, 20 miRNA families are involved in carcinogenesis induction and development to this moment. These families have 5p and 3p strands with different nucleotide (nt chain sizes. In general, mature 5p strands are larger: two miRNAs of 24 nt, 24 miRNAs of 23 nt, 35 miRNAs of 22 nt and three miRNAs of 21 nt. On the other hand, the 3p strands lengths observed are: seven miRNAs of 23 nt, 50 miRNAs of 22 nt, six miRNAs of 21 nt and four miRNAs of 20 nt. Based on the analysis of the 20 miRNA families associated with cervical cancer, 67 3p strands and 65 5p strands are selected suggesting selectivity and specificity mechanisms regulating cell processes like proliferation, apoptosis, migration, invasion, metabolism and Warburg effect. The insight reviewed here could be used in the miRNA based therapy, diagnosis and prognosis approaches.

    MicroRNAs (miRNAs) usually contain 19-24 nucleotides and have been identified as important eukaryotic gene regulators. Applications of various computational approaches have simplified the task by predicting miRNAs from available sequence data sources. In this study, we identified a conserved miR414 from a computational analysis of EST sequence data available from Stevia rebaudiana. In addition, we also identified six conserved miRNAs namely miR169, miR319, miR414, miR164, miR167 and miR398 using stem-loop RT-PCR analysis. Hence, miR414 was commonly identified using both methods. The expression analysis of these miRNAs documented their roles in growth and development of Stevia. Furthermore, the detected miRNAs were found to target genes involved in plant growth, development, metabolism and signal transduction. This is the first study reporting these conserved miRNAs and their expression in Stevia.

  6. "Seed-Milarity" confers to hsa-miR-210 and hsa-miR-147b similar functional activity.

    Directory of Open Access Journals (Sweden)

    Thomas Bertero

    Full Text Available Specificity of interaction between a microRNA (miRNA and its targets crucially depends on the seed region located in its 5'-end. It is often implicitly considered that two miRNAs sharing the same biological activity should display similarity beyond the strict six nucleotide region that forms the seed, in order to form specific complexes with the same mRNA targets. We have found that expression of hsa-miR-147b and hsa-miR-210, though triggered by different stimuli (i.e. lipopolysaccharides and hypoxia, respectively, induce very similar cellular effects in term of proliferation, migration and apoptosis. Hsa-miR-147b only shares a "minimal" 6-nucleotides seed sequence with hsa-miR-210, but is identical with hsa-miR-147a over 20 nucleotides, except for one base located in the seed region. Phenotypic changes induced after heterologous expression of miR-147a strikingly differ from those induced by miR-147b or miR-210. In particular, miR-147a behaves as a potent inhibitor of cell proliferation and migration. These data fit well with the gene expression profiles observed for miR-147b and miR-210, which are very similar, and the gene expression profile of miR-147a, which is distinct from the two others. Bioinformatics analysis of all human miRNA sequences indicates multiple cases of miRNAs from distinct families exhibiting the same kind of similarity that would need to be further characterized in terms of putative functional redundancy. Besides, it implies that functional impact of some miRNAs can be masked by robust expression of miRNAs belonging to distinct families.

    Compared with the sequence and expression similarity, miRNA functional similarity is so important for biology researches and many applications such as miRNA clustering, miRNA function prediction, miRNA synergism identification and disease miRNA prioritization. However, the existing methods always utilized the predicted miRNA target which has high false positive and false negative to calculate the miRNA functional similarity. Meanwhile, it is difficult to achieve high reliability of miRNA functional similarity with miRNA-disease associations. Therefore, it is increasingly needed to improve the measurement of miRNA functional similarity. In this study, we develop a novel path-based calculation method of miRNA functional similarity based on miRNA-disease associations, called MFSP. Compared with other methods, our method obtains higher average functional similarity of intra-family and intra-cluster selected groups. Meanwhile, the lower average functional similarity of inter-family and inter-cluster miRNA pair is obtained. In addition, the smaller p-value is achieved, while applying Wilcoxon rank-sum test and Kruskal-Wallis test to different miRNA groups. The relationship between miRNA functional similarity and other information sources is exhibited. Furthermore, the constructed miRNA functional network based on MFSP is a scale-free and small-world network. Moreover, the higher AUC for miRNA-disease prediction indicates the ability of MFSP uncovering miRNA functional similarity.

    MicroRNAs (miRNAs) control gene expression mostly post-transcriptionally by guiding transcript cleavage and/or translational repression of complementary mRNA targets, thereby regulating developmental processes and stress responses. Despite the remarkable expansion of the field, the mechanisms underlying miRNA activity are not fully understood. In this article, we describe a transient expression system in Arabidopsis mesophyll protoplasts, which is highly amenable for the dissection of miRNA pathways. We show that by transiently overexpressing primary miRNAs and target mimics, we can manipulate miRNA levels and consequently impact on their targets. Furthermore, we developed a set of luciferase-based sensors for quantifying miRNA activity that respond specifically to both endogenous and overexpressed miRNAs and target mimics. We demonstrate that these miRNA sensors can be used to test the impact of putative components of the miRNA pathway on miRNA activity, as well as the impact of specific mutations, by either overexpression or the use of protoplasts from the corresponding mutants. We further show that our miRNA sensors can be used for investigating the effect of chemicals on miRNA activity. Our cell-based transient expression system is fast and easy to set up, and generates quantitative results, being a powerful tool for assaying miRNA activity in vivo.

    Similar to the development of gene set enrichment and gene regulatory network analysis tools over a decade ago, microRNA enrichment tools are currently gaining importance. Building on our experience with the gene set analysis toolkit GeneTrail, we implemented the miRNA Enrichment Analysis and Annotation tool (miEAA). MiEAA is a web-based application that offers a variety of commonly applied statistical tests such as over-representation analysis and miRNA set enrichment analysis, which is similar to Gene Set Enrichment Analysis. Besides the different statistical tests, miEAA also provides rich functionality in terms of miRNA categories. Altogether, over 14 000 miRNA sets have been added, including pathways, diseases, organs and target genes. Importantly, our tool can be applied for miRNA precursors as well as mature miRNAs. To make the tool as useful as possible we additionally implemented supporting tools such as converters between different miRBase versions and converters from miRNA names to precursor names. We evaluated the performance of miEAA on two sets of miRNAs that are affected in lung adenocarcinomas and have been detected by array analysis. The web-based application is freely accessible at: http://www.ccb.uni-saarland.de/mieaa_tool/.

    miRNAs are a class of small non-coding RNAs that regulate gene expression. They are involved in the control of many developmental processes, including fruit development. The increasing amount of information on miRNAs, on their expression, abundance, and conservation between various species, provides a new opportunity to study the role of miRNAs in non-model plant species. In this work, we used a combination of Northern blot and tissue print hybridization analysis to identify conserved miRNAs expressed during prickly pear cactus (Opuntia ficus indica) fruit development. Comparative profiling detected the expression of 34 miRNAs, which were clustered in three different groups that were associated with the different phases of fruit development. Variation in the level of miRNA expression was observed. Gradual expression increase of several miRNAs was observed during fruit development, including miR164. miR164 was selected for stem-loop RT-PCR and for a detailed spatial-temporal expression analysis. At early floral stages, miR164 was mainly localized in meristematic tissues, boundaries and fusion zones, while it was more homogenously expressed in fruit tissues. Our results provide the first evidence of miRNA expression in the prickly pear cactus and provide the basis for future research on miRNAs in Opuntia. Moreover, our analyses suggest that miR164 plays different roles during prickly pear cactus fruit development.

    Rivers and effluents have been identified as major pathways for microplastics of terrestrial sources. Moreover, lakes of different dimensions and even in remote locations contain microplastics in striking abundances. This study investigates concentrations of microplastic particles at two lakes in central Italy (Lake Bolsena, Lake Chiusi). A total number of six Manta Trawls have been carried out, two of them one day after heavy winds occurred on Lake Bolsena showing effects on particle distribution of fragments and fibers of varying size categories. Additionally, 36 sediment samples from lakeshores were analyzed for microplastic content. In the surface waters 2.68 to 3.36 particles/m(3) (Lake Chiusi) and 0.82 to 4.42 particles/m(3) (Lake Bolsena) were detected, respectively. Main differences between the lakes are attributed to lake characteristics such as surface and catchment area, depth and the presence of local wind patterns and tide range at Lake Bolsena. An event of heavy winds and moderate rainfall prior to one sampling led to an increase of concentrations at Lake Bolsena which is most probable related to lateral land-based and sewage effluent inputs. The abundances of microplastic particles in sediments vary from mean values of 112 (Lake Bolsena) to 234 particles/kg dry weight (Lake Chiusi). Lake Chiusi results reveal elevated fiber concentrations compared to those of Lake Bolsena what might be a result of higher organic content and a shift in grain size distribution towards the silt and clay fraction at the shallow and highly eutrophic Lake Chiusi. The distribution of particles along different beach levels revealed no significant differences.

Results High expression of miR-21 was observed in cervical cancer and Hela cell, while low expression was observed in normal cervical tissue. The relative quantification of miR-21 in cerveical cancer was 11.3196 times that of miR-21 in normal cervical tissue (P0. 05). Conclusion miRNAs are closely related to the occurrence and regulation of cervical cancer. The high expression of miR-21 in cervical cancer and Hela cell indicate that it may play a possible role of oncogenes, while miR-143 and miR-373 with low expression may play the role of tumor suppressor genes.

    The author has identified the following significant results. Computer techniques developed for mapping water quality parameters from LANDSAT data were demonstrated, using ground truth collected in an ongoing survey of water quality in Saginaw Bay (Lake Huron), Michigan. Regression correlation coefficients varied from 0.99 for total phosphorus to 0.72 for chlorophyll-a corrected. Five water quality parameters are best correlated with LANDSAT band 6 alone. Temperature relates to band 5 alone and only two bands are justified for mapping the remaining six parameters. LANDSAT CCTs were used as a basis for inventorying land use within each of the Ohio-Kentucky-Indiana regional commissions, 225 drainage areas, and nine counties. Sixteen categories were merged into ten categories and mapped at a scale of 1 in. = 5,000 ft, with detail to 0.44 hectares for the 2,700 sq mi region. These products were produced in less than 90 days at a cost of one cent an acre. LANDSAT CCTS were also used as a basis for inventorying land cover within the Triangle J council of governments 1,750 sq mi study area. The complete inventory was accomplished within a period of 60 days at a cost of about one half cent per acre.

    Water samples collected from four perennially ice-covered Antarctic lakes during the austral summer of 1996-1997 contained high densities of extracellular viruses. Many of these viruses were found to be morphologically similar to double-stranded DNA viruses that are known to infect algae and protozoa. These constitute the first observations of viruses in perennially ice-covered polar lakes. The abundance of planktonic viruses and data suggesting substantial production potential (relative to bacteria] secondary and photosynthetic primary production) indicate that viral lysis may be a major factor in the regulation of microbial populations in these extreme environments. Furthermore, we suggest that Antarctic lakes may be a reservoir of previously undescribed viruses that possess novel biological and biochemical characteristics.

    A screen of microRNA (miRNA) expression following differentiation in human foreskin keratinocytes (HFKs) identified changes in several miRNAs, including miR-24 and miR-205. We investigated how expression of Human Papilloma Virus Type-16 (HPV16) onco-proteins E6 and E7 affected expression of miR-24 and miR-205 during proliferation and differentiation of HFKs. We show that the induction of both miR-24 and miR-205 observed during differentiation of HFKs is lost in HFKs expressing E6 and E7. We demonstrate that the effect on miR-205 is due to E7 activity, as miR-205 expression is dependent on pRb expression. Finally, we provide evidence that miR-24 effects in the cell may be due to targeting of cyclin dependent kinase inhibitor p27. In summary, these results indicate that expression of both miR-24 and miR-205 are impacted by E6 and/or E7 expression, which may be one mechanism by which HPV onco-proteins can disrupt the balance between proliferation and differentiation in keratinocytes. - Highlights: • miR-24 and miR-205 are induced during keratinocyte differentiation. • This induction is lost in keratinocytes expressing HPV onco-proteins E6 and E7. • miR-205 is dependent upon pRb expression. • miR-24 targets p27 in cycling keratinocytes.

    2017-01-01

    BACKGROUND Dengue is considered one of the world’s most important mosquito-borne diseases. MicroRNAs (miRNAs) are small non-coding single-stranded RNAs that play an important role in the regulation of gene expression in eukaryotes. Although miRNAs possess antiviral activity against many mammalian-infecting viruses, their involvement in Dengue virus (DENV) replication remains poorly understood. OBJECTIVE To determine the role of miR-484 and miR-744 in DENV infection and to examine whether DENV infection alters the expression of both miRNAs. METHODS We used bioinformatics tools to explore the relationship between DENV and cellular miRNAs. We then overexpressed miR-484 or miR-744 in Vero cells to examine their role in DENV replication using flow cytometry, reverse transcriptase quantitative polymerase chain reaction (RT-qPCR), and western blotting. FINDINGS We found several cellular miRNAs that target a conserved region within the 3′ untranslated region (3′ UTR) of the genome of the four DENV serotypes and found that overexpression of miR-484 or miR-744 inhibits infection by DENV-1 to DENV-4. Furthermore, we observed that DENV RNA might be involved in the downregulation of endogenous miR-484 and miR-744. CONCLUSION Our study identifies miR-484 and miR-744 as two possible restriction host factors against DENV infection. However, further studies are needed to directly verify whether miR-484 and miR-744 both have an anti-DENV effect in vivo. PMID:28327787

    Research highlights: {yields} The expression of miR-132 and miR-212 are significantly increased in pancreatic cancer. {yields} miR-132 and miR-212 target the tumor suppressor pRb, resulting in enhanced proliferation. {yields} miR-132 and miR-212 expression is increased by a {beta}2 adrenergic receptor agonist, suggesting a novel mechanism for pancreatic cancer progression. -- Abstract: Numerous microRNAs (miRNAs) are reported as differentially expressed in cancer, however the consequence of miRNA deregulation in cancer is unknown for many miRNAs. We report that two miRNAs located on chromosome 17p13, miR-132 and miR-212, are over-expressed in pancreatic adenocarcinoma (PDAC) tissues. Both miRNAs are predicted to target the retinoblastoma tumor suppressor, Rb1. Validation of this interaction was confirmed by luciferase reporter assay and western blot in a pancreatic cancer cell line transfected with pre-miR-212 and pre-miR-132 oligos. Cell proliferation was enhanced in Panc-1 cells transfected with pre-miR-132/-212 oligos. Conversely, antisense oligos to miR-132/-212 reduced cell proliferation and caused a G{sub 2}/M cell cycle arrest. The mRNA of a number of E2F transcriptional targets were increased in cells over expressing miR-132/-212. Exposing Panc-1 cells to the {beta}2 adrenergic receptor agonist, terbutaline, increased the miR-132 and miR-212 expression by 2- to 4-fold. We report that over-expression of miR-132 and miR-212 result in reduced pRb protein in pancreatic cancer cells and that the increase in cell proliferation from over-expression of these miRNAs is likely due to increased expression of several E2F target genes. The {beta}2 adrenergic pathway may play an important role in this novel mechanism.

    Full Text Available Lakes are suffering from different stress factors and need to be restored using different approaches. The eutrophication remains as the main water quality management problem for inland waters: both lakes and reservoirs. The way to curb the degradation is to stop the nutrient sources and to accelerate the restoration with help of in-lake technologies. Especially lakes with a long retention time need (eco- technological help to decrease the nutrient content in the free water. The microbial and other organic matter from sewage and other autochthonous biomasses, causes oxygen depletion, which has many adverse effects. In less developed countries big reservoirs function as sewage treatment plants. Natural aeration solves problems only partly and many pollutants tend to accumulate in the sediments. The acidification by acid rain and by pyrite oxidation has to be controlled by acid neutralizing technologies. Addition of alkaline chemicals is useful only for soft waters, and technologies for (microbial alkalinization of very acidic hardwater mining lakes are in development. The corrective measures differ from those in use for eutrophication control. The salinization and water shortage mostly occurs if more water is used than available. L. Aral, L. Tschad, the Dead Sea or L. Nasser belong to waters with most severe environmental problems on a global scale. Their hydrologic regime needs to be evaluated. The inflow of salt water at the bottom of some mining lakes adds to stability of stratification, and thus accumulation of hydrogen sulphide in the monimolimnion of the meromictic lakes. Destratification, which is the most used technology, is only restricted applicable because of the dangerous concentrations of the byproducts of biological degradation. The contamination of lakes with hazardous substances from industry and agriculture require different restoration technologies, including subhydric isolation and storage, addition of nutrients for better self

    On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critic

    Exosomes, which are one of the smallest extracellular vesicles released from cells, have been shown to carry different nucleic acids, including microRNAs (miRNAs). miRNAs significantly regulate cell growth and metabolism by posttranscriptional inhibition of gene expression. The rapidly changing understanding of exosomes' formation and function in delivering miRNAs from cell to cell has prompted us to review current knowledge in exosomal miRNA secretion mechanisms as well as possible therapeutic applications for personalized medicine.

  13. Reevaluation of lake trout and lake whitefish bioenergetics models

    2013-01-01

    Using a corrected algorithm for balancing the energy budget, we reevaluated the Wisconsin bioenergetics model for lake trout (Salvelinus namaycush) in the laboratory and for lake whitefish (Coregonus clupeaformis) in the laboratory and in the field. For lake trout, results showed that the bioenergetics model slightly overestimated food consumption by the lake trout when they were fed low and intermediate rations, whereas the model predicted food consumption by lake trout fed ad libitum without any detectable bias. The slight bias in model predictions for lake trout on restricted rations may have been an artifact of the feeding schedule for these fish, and we would therefore recommend application of the Wisconsin lake trout bioenergetics model to lake trout populations in the field without any revisions to the model. Use of the Wisconsin bioenergetics model for coregonids resulted in overestimation of food consumption by lake whitefish both in the laboratory and in the field by between 20 and 30%, on average. This overestimation of food consumption was most likely due to overestimation of respiration rate. We therefore adjusted the respiration component of the bioenergetics model to obtain a good fit to the observed consumption in our laboratory tanks. The adjusted model predicted the consumption in the laboratory and the field without any detectable bias. Until a detailed lake whitefish respiration study can be conducted, we recommend application of our adjusted version of the Wisconsin generalized coregonid bioenergetics model to lake whitefish populations in the field.

  15. miRNAting control of DNA methylation

    Indian Academy of Sciences (India)

    Ashwani Jha; Ravi Shankar

    2014-06-01

    DNA methylation is a type of epigenetic modification where a methyl group is added to the cytosine or adenine residue of a given DNA sequence. It has been observed that DNA methylation is achieved by some collaborative agglomeration of certain proteins and non-coding RNAs. The assembly of IDN2 and its homologous proteins with siRNAs recruits the enzyme DRM2, which adds a methyl group at certain cytosine residues within the DNA sequence. In this study, it was found that de novo DNA methylation might be regulated by miRNAs through systematic targeting of the genes involved in DNA methylation. A comprehensive genome-wide and system-level study of miRNA targeting, transcription factors, DNA-methylation-causing genes and their target genes has provided a clear picture of an interconnected relationship of all these factors which regulate DNA methylation in Arabidopsis. The study has identified a DNA methylation system that is controlled by four different genes: IDN2, IDNl1, IDNl2 and DRM2. These four genes along with various critical transcription factors appear to be controlled by five different miRNAs. Altogether, DNA methylation appears to be a finely tuned process of opposite control systems of DNA-methylation-causing genes and certain miRNAs pitted against each other.

    Brucellosis is a zoonotic disease that is still endemic in developing countries. Despite early diagnosis and treatment of patients, chronic infections are seen in 10-30% of patients. In this study, we aimed to investigate the immunological factors that play roles in the transition of brucellosis from acute infection into chronic infection. Here, more than 2000 miRNAs were screened in peripheral blood mononuclear cells (PBMCs) of patients with acute or chronic brucellosis and healthy controls by using miRNA array, and the results of the miRNA array were validated through qRT-PCR. Findings were evaluated using GeneSpring GX (Agilent) 13.0 software and KEGG pathway analysis. Four miRNAs were expressed in the chronic group but were not expressed in acute and control groups. Among these miRNAs, the expression level of miR-1238-3p was increased while miR-494, miR-6069, and miR-139-3p were decreased (p 2). These miRNAs have the potential to be markers for chronic cases. The differentially expressed miRNAs and their predicted target genes involved in endocytosis, regulation of actin cytoskeleton, MAPK signaling pathway, and cytokine-cytokine receptor interaction and its chemokine signaling pathway indicate their potential roles in chronic brucellosis and its progression. It is the first study of miRNA expression analysis of human PBMC to clarify the mechanism of inveteracy in brucellosis.

    The porcine brain closely resembles the human brain in aspects such as development and morphology. Temporal miRNA profiling in the developing embryonic porcine cortex revealed a distinct set of miRNAs, including miR-34c and miR-204, which exhibited a highly specific expression profile across the time of cortical folding. These miRNAs were found to target Doublecortin (DCX), known to be involved in neuron migration during cortical folding of gyrencephalic brains. In vivo modulation of miRNA expression in mouse embryos confirmed that miR-34c and miR-204 can control neuronal migration and cortical morphogenesis, presumably by posttranscriptional regulation of DCX.

    Acid soils limit agricultural production worldwide. Major reason of crop losses in acid soils is the toxicity of aluminum (Al). In the present work, we investigated expression alterations of microRNAs in flax (Linum usitatissimum L.) plants under Al stress. Flax seedlings of resistant (TMP1919 and G1071/4_k) and sensitive (Lira and G1071/4_o) to Al cultivars and lines were exposed to AlCl3 solution for 4 and 24 hours. Twelve small RNA libraries were constructed and sequenced using Illumina platform. In total, 97 microRNAs from 18 conserved families were identified. miR319, miR390, and miR393 revealed expression alterations associated with Al treatment of flax plants. Moreover, for miR390 and miR393, the alterations were distinct in sensitive and resistant to Al genotypes. Expression level changes of miR319 and miR390 were confirmed using qPCR analysis. In flax, potential targets of miR319 are TCPs, miR390–TAS3 and GRF5, and miR393–AFB2-coding transcripts. TCPs, TAS3, GRF5, and AFB2 participate in regulation of plant growth and development. The involvement of miR319, miR390, and miR393 in response to Al stress in flax was shown here for the first time. We speculate that these microRNAs play an important role in Al response via regulation of growth processes in flax plants.

    Objective: To study the expression of miR-126 and miR-223 in platelet of rabbit arterial plaque models, and explore its correlation with plaque morphology. Methods: Rabbit arterial plaque models were established, peripheral blood of models and control animals was collected. Plaque morphologies were divided into type Ⅰ, type Ⅱ and type Ⅲ based on angiography plaque morphology and Ambrose method. Platelet isolation kit was applied to isolate and purify peripheral blood platelets, CD45 immunomagnetic beads were used to remove the residual white blood cells. The miRNAs of platelets was extracted by miRNA Isolation Kit, and expressions of miR-126 and miR-223 of the platelets samples were detected by Real-time PCR. The correlation between plaque morphology and platelet-associated miR-126 and miR-223 expressions were analyzed. Expressions of target gene VCAM-1 and P2Y12 receptors of miR-126 and miR-223 in the atherosclerosis plaque of rabbit model were detected by Western blot. Results: Relative expression levels of miR-126 and miR-223 in the model group were 0.27±0.10 and 0.71±0.14, respectively. Plaque morphology was divided into types Ⅰ, Ⅱ and Ⅲ;and miR-126 and miR-223 expression levels were detected in each type. Expression levels of miR-126 in each type were 0.42±0.07, 0.17±0.11 and 0.22±0.15, respectively; and expression levels of miR-223 in each type are 0.68±0.02, 0.57±0.06 and 0.88±0.10, respectively. Relative to the control group, miR-126 and miR-223 known target genes in VCAM-1 and P2Y12 receptors increased platelets in rabbit atherosclerotic plaque models (P<0.05). Conclusions:Relative to normal control animals, miR-126 and miR-223 platelets were reduced in the rabbit atherosclerotic plaque model group (P<0.05). In the type Ⅱ plaque morphology group, miR-126 was greatly reduced; and there is no significant correlation between miR-223 and plaque morphology.

    Lake Whitefish Coregonus clupeaformis support some of the most valuable commercial freshwater fisheries in North America. Recent growth and condition decreases in Lake Whitefish populations in the Great Lakes have been attributed to the invasion of the dreissenid mussels, zebra mussels Dreissena polymorpha and quagga mussels D. bugensis, and the subsequent collapse of the amphipod, Diporeia, a once-abundant high energy prey source. Since 1993, Lake Champlain has also experienced the invasion and proliferation of zebra mussels, but in contrast to the Great Lakes, Diporeia were not historically abundant. We compared the diet, condition, and energy density of Lake Whitefish from Lake Champlain after the dreissenid mussel invasion to values for those of Lake Whitefish from Lakes Michigan, Huron, Erie, and Ontario. Lake Whitefish were collected using gill nets and bottom trawls, and their diets were quantified seasonally. Condition was estimated using Fulton's condition factor (K) and by determining energy density. In contrast to Lake Whitefish from some of the Great Lakes, those from Lake Champlain Lake Whitefish did not show a dietary shift towards dreissenid mussels, but instead fed primarily on fish eggs in spring, Mysis diluviana in summer, and gastropods and sphaeriids in fall and winter. Along with these dietary differences, the condition and energy density of Lake Whitefish from Lake Champlain were high compared with those of Lake Whitefish from Lakes Michigan, Huron, and Ontario after the dreissenid invasion, and were similar to Lake Whitefish from Lake Erie; fish from Lakes Michigan, Huron, and Ontario consumed dreissenids, whereas fish from Lake Erie did not. Our comparisons of Lake Whitefish populations in Lake Champlain to those in the Great Lakes indicate that diet and condition of Lake Champlain Lake Whitefish were not negatively affected by the dreissenid mussel invasion.

    Ifedinma Dimbo currently lives in Dublin, where she works and researches for her PhD in Medical Sociology. The Nigerian-born, Irish-based writer was kind enough to answer my questions via e-mail between the months of August and October 2014, with some final elaboration in January 2015. Ifedinma Dimbo’s writing, as well as her answers in this interview, are an invaluable testimony to a reality that is currently taking place in Ireland and has often been silenced. Now that Irish society is beginning to be aware of the unfair treatment that refugees and asylum seekers receive at the hands of the Irish system, it is high time to let people who, like Ifedinma Dimbo, have made Ireland their home, have their voices heard in the field of Irish Studies. In this interview, Ifedinma Dimbo very sharply shares her views on writing, immigration, religion and Irish society.

    1996-07-01

    Above-normal precipitation and surface-water runoff, which have been generally related to the cyclic recurrence of the El Nino-Southern Oscillation, have produced modern ephemeral lakes in the closed-basin Death Valley watershed. This study evaluates the regional hydroclimatic relations between precipitation, runoff, and lake transgressions in the Death Valley watershed. Recorded precipitation, runoff, and spring discharge data for the region are used in conjunction with a closed-basin, lake-water-budget equation to assess the relative contributions of water from these sources to modern lakes in Death Valley and to identify the requisite hydroclimatic changes for a late Holocene perennial lake in the valley. As part of the Yucca Mountain Site Characterization Program, an evaluation of the Quaternary regional paleoflood hydrology of the potential nuclear-waste repository site at Yucca Mountain, Nevada, was planned. The objectives of the evaluation were (1) to identify the locations and investigate the hydraulic characteristics of paleofloods and compare these with the locations and characteristics of modern floods, and (2) to evaluate the character and severity of past floods and debris flows to ascertain the potential future hazards to the potential repository during the pre-closure period (US Department of Energy, 1988). This study addresses the first of these objectives, and the second in part, by assessing and comparing the sizes, locations, and recurrence rates of modern, recorded (1962--83) floods and late Holocene paleofloods for the 8,533-mi{sup 2}, closed-basin, Death Valley watershed with its contributing drainage basins in the Yucca Mountain site area.

    Full Text Available MicroRNAs (miRNAs present diverse regulatory functions in a wide range of biological activities. Studies on miRNA functions generally depend on determining miRNA expression profiles between libraries by using a next-generation sequencing (NGS platform. Currently, several online web services are developed to provide small RNA NGS data analysis. However, the submission of large amounts of NGS data, conversion of data format, and limited availability of species bring problems. In this study, we developed miRSeq to provide alternatives. To test the performance, we had small RNA NGS data from four species, including human, rat, fly, and nematode, analyzed with miRSeq. The alignments results indicate that miRSeq can precisely evaluate the sequencing quality of samples regarding percentage of self-ligation read, read length distribution, and read category. miRSeq is a user-friendly standalone toolkit featuring a graphical user interface (GUI. After a simple installation, users can easily operate miRSeq on a PC or laptop by using a mouse. Within minutes, miRSeq yields useful miRNA data, including miRNA expression profiles, 3′ end modification patterns, and isomiR forms. Moreover, miRSeq supports the analysis of up to 105 animal species, providing higher flexibility.

    Soda lakes are saline and alkaline ecosystems that are believed to have existed throughout the geological record of Earth. They are widely distributed across the globe, but are highly abundant in terrestrial biomes such as deserts and steppes and in geologically interesting regions such as the East African Rift valley. The unusual geochemistry of these lakes supports the growth of an impressive array of microorganisms that are of ecological and economic importance. Haloalkaliphilic Bacteria and Archaea belonging to all major trophic groups have been described from many soda lakes, including lakes with exceptionally high levels of heavy metals. Lonar Lake is a soda lake that is centered at an unusual meteorite impact structure in the Deccan basalts in India and its key physicochemical and microbiological characteristics are highlighted in this article. The occurrence of diverse functional groups of microbes, such as methanogens, methanotrophs, phototrophs, denitrifiers, sulfur oxidizers, sulfate reducers and syntrophs in soda lakes, suggests that these habitats harbor complex microbial food webs that (a) interconnect various biological cycles via redox coupling and (b) impact on the production and consumption of greenhouse gases. Soda lake microorganisms harbor several biotechnologically relevant enzymes and biomolecules (for example, cellulases, amylases, ectoine) and there is the need to augment bioprospecting efforts in soda lake environments with new integrated approaches. Importantly, some saline and alkaline lake ecosystems around the world need to be protected from anthropogenic pressures that threaten their long-term existence.

  16. Lake trout rehabilitation in Lake Erie: a case history

    Native lake trout (Salvelinus namaycush) once thrived in the deep waters of eastern Lake Erie. The impact of nearly 70 years of unregulated exploitation and over 100 years of progressively severe cultural eutrophication resulted in the elimination of lake trout stocks by 1950. Early attempts to restore lake trout by stocking were unsuccessful in establishing a self-sustaining population. In the early 1980s, New York's Department of Environmental Conservation, Pennsylvania's Fish and Boat Commission, and the U.S. Fish and Wildlife Service entered into a cooperative program to rehabilitate lake trout in the eastern basin of Lake Erie. After 11 years of stocking selected strains of lake trout in U.S. waters, followed by effective sea lamprey control, lake trout appear to be successfully recolonizing their native habitat. Adult stocks have built up significantly and are expanding their range in the lake. Preliminary investigations suggest that lake trout reproductive habitat is still adequate for natural reproduction, but natural recruitment has not been documented. Future assessments will be directed toward evaluation of spawning success and tracking age-class cohorts as they move through the fishery.

    MiRNA remain stable for detection and PCR-based amplification in FFPE tissue samples. Several miRNA extraction kits are available, however miRNA fraction, as part of total RNA can be isolated using total RNA purification methods, as well. Our primary aim was to compare four different miRNA and total RNA isolation methods from FFPE tissues. Further purposes were to evaluate quantitatively and qualitatively the yield of the isolated miRNA. MiRNAs were isolated from normal colorectal cancer FFPE specimens from the same patients. Two miRNA isolation kits (High Pure miRNA Isolation Kit, miRCURY™ RNA Isolation Kit) and two total RNA isolation kits were compared (High Pure RNA Paraffin Kit, MagNA Pure 96 Cellular RNA LV Kit). Quantity and quality were determined, expression analysis was performed by real-time PCR using qPCR Human Panel I + II (Exiqon) method detecting 742 human miRNAs in parallel. The yield of total RNA was found to be higher than miRNA purification protocols (in CRC: Ex: 0203 ± 0021 μg; HPm: 1,45 ± 0,8 μg; HPp: 21,36 ± 4,98 μg; MP: 8,6 ± 5,1 μg). MiRNAs were detected in lower relative quantity of total RNA compared to the miRNA kits. Higher number of miRNAs could be detected by the miRNA isolation kits in comparison to the total RNA isolation methods. (Ex: 497 ± 16; HPm: 542 ± 11; HPp: 332 ± 36; MP: 295 ± 74). Colon specific miRNAs (miR-21-5p;-34-5p) give satisfying results by miRNA isolation kits. Although miRNA can be detected also after total RNA isolation methods, for reliable and reproducible miRNA expression profiling the use of miRNA isolation kits are more suitable.

    Conclusions: Based on the initial miRNA findings, this study elucidates the dys-regulation of four miRNAs in three separate NB chemoresistant cell line models, spanning two cell lines (SH-SY5Y and UKF-NB-3 and two chemotherapeutic agents (doxorubicin and etoposide. These miRNAs may thus be possibly linked to chemoresistance induction in NB. Such miRNAs are good candidates to be novel drug targets for future miRNA based therapies against aggressive tumours that are not responding to conventional chemotherapy.

    Recent evidence shows that certain microRNAs (miRNAs) play a role in both obesity and prostate cancer recurrence,but the association between the expression of these miRNAs and obesity in prostate cancer recurrence is unknown.In this study,we examined the effect of the interaction between obesity and miR-21,miR-221 or miR-222 expression on prostate cancer recurrence among 28 recurrent and 37 non-recurrent prostate cancer cases,miRNA expression was determined using quantitative real-time polymerase chain reaction.Cox proportional hazard models adjusting for age at diagnosis,clinical stage and Gleason score were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for recurrence free survival.A significantly (P=0.014) higher proportion of recurrent cases (78.6%) than non-recurrent cases (48.6%) had a low expression of miR-21 and the difference was more prominent in obese than non-obese patients.Multivariate analysis showed that the expression of miR-21 was an independent risk factor for recurrence in obese (HR=6.15,95% CI=1.04-36.48,P=0.045),but not in non-obese (HR=1.28,95% CI=0.30-5.49,P=0.74) cases.A significant association with recurrence was not observed for the expression of miR-221 and miR-222.In summary,our findings show that miR-21 is associated with prostate cancer recurrence after radical prostatectomy and suggest that the differential expression of miR-21 is more prominent in obese than in non-obese cases.Future larger studies are warranted to confirm these initial findings and to elucidate the mechanisms involved.

    In miRNA biogenesis, pri-miRNA transcripts are converted into pre-miRNA hairpins. The in vivo properties of this process remain enigmatic. Here, we determine in vivo transcriptome-wide pri-miRNA processing using next-generation sequencing of chromatin-associated pri-miRNAs. We identify a distinctive Microprocessor signature in the transcriptome profile from which efficiency of the endogenous processing event can be accurately quantified. This analysis reveals differential susceptibility to Microprocessor cleavage as a key regulatory step in miRNA biogenesis. Processing is highly variable among pri-miRNAs and a better predictor of miRNA abundance than primary transcription itself. Processing is also largely stable across three cell lines, suggesting a major contribution of sequence determinants. On the basis of differential processing efficiencies, we define functionality for short sequence features adjacent to the pre-miRNA hairpin. In conclusion, we identify Microprocessor as the main hub for diversified miRNA output and suggest a role for uncoupling miRNA biogenesis from host gene expression.

    Neuronal activity regulates a broad range of processes in the hippocampus, including the precise regulation of translation. Disruptions in proper translational control in the nervous system are associated with a variety of disorders that fall in the autistic spectrum. MicroRNA (miRNA) represent a relatively recently discovered player in the regulation of translation in the nervous system. We have conducted an in depth analysis of how neuronal activity regulates miRNA expression in the hippocampus. Using deep sequencing we exhaustively identify all miRNAs, including 15 novel miRNAs, expressed in hippocampus of the adult mouse. We identified 119 miRNAs documented in miRBase but less than half of these miRNA were expressed at a level greater than 0.1% of total miRNA. Expression profiling following induction of neuronal activity by electroconvulsive shock demonstrates that most miRNA show a biphasic pattern of expression: rapid induction of specific mature miRNA expression followed by a decline in expression. These results have important implications into how miRNAs influence activity-dependent translational control. PMID:21984899

    2013-10-15

    Technological improvements have resulted in increased discovery of new microRNAs (miRNAs) and refinement and enrichment of existing miRNA families. miRNA families are important because they suggest a common sequence or structure configuration in sets of genes that hint to a shared function. Exploratory tools to enhance investigation of characteristics of miRNA families and the functions of family-specific miRNA genes are lacking. We have developed, miRNAVISA, a user-friendly web-based tool that allows customized interrogation and comparisons of miRNA families for hypotheses generation, and comparison of per-species chromosomal distribution of miRNA genes in different families. This study illustrates hypothesis generation using miRNAVISA in seven species. Our results unveil a subclass of miRNAs that may be regulated by genomic imprinting, and also suggest that some miRNA families may be species-specific, as well as chromosome- and/or strand-specific.

  5. Entropy-based model for miRNA isoform analysis.

    Shengqin Wang

    Full Text Available MiRNAs have been widely studied due to their important post-transcriptional regulatory roles in gene expression. Many reports have demonstrated the evidence of miRNA isoform products (isomiRs in high-throughput small RNA sequencing data. However, the biological function involved in these molecules is still not well investigated. Here, we developed a Shannon entropy-based model to estimate isomiR expression profiles of high-throughput small RNA sequencing data extracted from miRBase webserver. By using the Kolmogorov-Smirnov statistical test (KS test, we demonstrated that the 5p and 3p miRNAs present more variants than the single arm miRNAs. We also found that the isomiR variant, except the 3' isomiR variant, is strongly correlated with Minimum Free Energy (MFE of pre-miRNA, suggesting the intrinsic feature of pre-miRNA should be one of the important factors for the miRNA regulation. The functional enrichment analysis showed that the miRNAs with high variation, particularly the 5' end variation, are enriched in a set of critical functions, supporting these molecules should not be randomly produced. Our results provide a probabilistic framework for miRNA isoforms analysis, and give functional insights into pre-miRNA processing.

    Tissue repair and regeneration rely on the function of miRNA, molecular silencers that enact post-transcriptional gene silencing of coding genes. Disruption of miRNA homeostasis is developmentally lethal, indicating that fetal tissue development is tightly controlled by miRNAs. Multiple critical facets of adult tissue repair are subject to control by miRNAs, as well. Sources of cell pool for tissue repair and regeneration are diverse and provided by processes including cellular dedifferentiation, transdifferentiation, and reprogramming. Each of these processes is regulated by miRNAs. Furthermore, induced pluripotency may be achieved by miRNA-based strategies independent of transcription factor manipulation. The observation that miRNA does not integrate into the genome makes miRNA-based therapeutic strategies translationally valuable. Tools to manipulate cellular and tissue miRNA levels include mimics and inhibitors that may be specifically targeted to cells of interest at the injury site. Here, we discuss the extraordinary importance of miRNAs in tissue repair and regeneration based on emergent reports and rapid advances in miRNA-based therapeutics.

  7. Exosomal miRNAs as cancer biomarkers and therapeutic targets

    2016-07-01

    Full Text Available Intercommunication between cancer cells and with their surrounding and distant environments is key to the survival, progression and metastasis of the tumour. Exosomes play a role in this communication process. MicroRNA (miRNA expression is frequently dysregulated in tumour cells and can be reflected by distinct exosomal miRNA (ex-miRNA profiles isolated from the bodily fluids of cancer patients. Here, the potential of ex-miRNA as a cancer biomarker and therapeutic target is critically analysed. Exosomes are a stable source of miRNA in bodily fluids but, despite a number of methods for exosome extraction and miRNA quantification, their suitability for diagnostics in a clinical setting is questionable. Furthermore, exosomally transferred miRNAs can alter the behaviour of recipient tumour and stromal cells to promote oncogenesis, highlighting a role in cell communication in cancer. However, our incomplete understanding of exosome biogenesis and miRNA loading mechanisms means that strategies to target exosomes or their transferred miRNAs are limited and not specific to tumour cells. Therefore, if ex-miRNA is to be employed in novel non-invasive diagnostic approaches and as a therapeutic target in cancer, two further advances are necessary: in methods to isolate and detect ex-miRNA, and a better understanding of their biogenesis and functions in tumour-cell communication.

  11. Prognostic significance of miR-205 in endometrial cancer.

    Directory of Open Access Journals (Sweden)

    Mihriban Karaayvaz

    Full Text Available PURPOSE: microRNAs have emerged as key regulators of gene expression, and their altered expression has been associated with tumorigenesis and tumor progression. Thus, microRNAs have potential as both cancer biomarkers and/or potential novel therapeutic targets. Although accumulating evidence suggests the role of aberrant microRNA expression in endometrial carcinogenesis, there are still limited data available about the prognostic significance of microRNAs in endometrial cancer. The goal of this study is to investigate the prognostic value of selected key microRNAs in endometrial cancer by the analysis of archival formalin-fixed paraffin-embedded tissues. EXPERIMENTAL DESIGN: Total RNAs were extracted from 48 paired normal and endometrial tumor specimens using Trizol based approach. The expression of miR-26a, let-7g, miR-21, miR-181b, miR-200c, miR-192, miR-215, miR-200c, and miR-205 were quantified by real time qRT-PCR expression analysis. Targets of the differentially expressed miRNAs were quantified using immunohistochemistry. Statistical analysis was performed by GraphPad Prism 5.0. RESULTS: The expression levels of miR-200c (P<0.0001 and miR-205 (P<0.0001 were significantly increased in endometrial tumors compared to normal tissues. Kaplan-Meier survival analysis revealed that high levels of miR-205 expression were associated with poor patient overall survival (hazard ratio, 0.377; Logrank test, P = 0.028. Furthermore, decreased expression of a miR-205 target PTEN was detected in endometrial cancer tissues compared to normal tissues. CONCLUSION: miR-205 holds a unique potential as a prognostic biomarker in endometrial cancer.

  12. Role of miRNA-9 in Brain Development

    2016-01-01

    MicroRNAs (miRNAs) are a class of small regulatory RNAs involved in gene regulation. The regulation is effected by either translational inhibition or transcriptional silencing. In vertebrates, the importance of miRNA in development was discovered from mice and zebrafish dicer knockouts. The miRNA-9 (miR-9) is one of the most highly expressed miRNAs in the early and adult vertebrate brain. It has diverse functions within the developing vertebrate brain. In this article, the role of miR-9 in the developing forebrain (telencephalon and diencephalon), midbrain, hindbrain, and spinal cord of vertebrate species is highlighted. In the forebrain, miR-9 is necessary for the proper development of dorsoventral telencephalon by targeting marker genes expressed in the telencephalon. It regulates proliferation in telencephalon by regulating Foxg1, Pax6, Gsh2, and Meis2 genes. The feedback loop regulation between miR-9 and Nr2e1/Tlx helps in neuronal migration and differentiation. Targeting Foxp1 and Foxp2, and Map1b by miR-9 regulates the radial migration of neurons and axonal development. In the organizers, miR-9 is inversely regulated by hairy1 and Fgf8 to maintain zona limitans interthalamica and midbrain–hindbrain boundary (MHB). It maintains the MHB by inhibiting Fgf signaling genes and is involved in the neurogenesis of the midbrain–hindbrain by regulating Her genes. In the hindbrain, miR-9 modulates progenitor proliferation and differentiation by regulating Her genes and Elav3. In the spinal cord, miR-9 modulates the regulation of Foxp1 and Onecut1 for motor neuron development. In the forebrain, midbrain, and hindbrain, miR-9 is necessary for proper neuronal progenitor maintenance, neurogenesis, and differentiation. In vertebrate brain development, miR-9 is involved in regulating several region-specific genes in a spatiotemporal pattern. PMID:27721656

    In this study, we describe miRSponge, a manually curated database, which aims at providing an experimentally supported resource for microRNA (miRNA) sponges. Recent evidence suggests that miRNAs are themselves regulated by competing endogenous RNAs (ceRNAs) or 'miRNA sponges' that contain miRNA binding sites. These competitive molecules can sequester miRNAs to prevent them interacting with their natural targets to play critical roles in various biological and pathological processes. It has become increasingly important to develop a high quality database to record and store ceRNA data to support future studies. To this end, we have established the experimentally supported miRSponge database that contains data on 599 miRNA-sponge interactions and 463 ceRNA relationships from 11 species following manual curating from nearly 1200 published articles. Database classes include endogenously generated molecules including coding genes, pseudogenes, long non-coding RNAs and circular RNAs, along with exogenously introduced molecules including viral RNAs and artificial engineered sponges. Approximately 70% of the interactions were identified experimentally in disease states. miRSponge provides a user-friendly interface for convenient browsing, retrieval and downloading of dataset. A submission page is also included to allow researchers to submit newly validated miRNA sponge data. Database URL: http://www.bio-bigdata.net/miRSponge.

    2015-08-13

    The precise control of miR-17∼92 microRNA (miRNA) is essential for normal development, and overexpression of certain miRNAs from this cluster is oncogenic. Here, we find that the relative expression of the six miRNAs processed from the primary (pri-miR-17∼92) transcript is dynamically regulated during embryonic stem cell (ESC) differentiation. Pri-miR-17∼92 is processed to a biogenesis intermediate, termed "progenitor-miRNA" (pro-miRNA). Pro-miRNA is an efficient substrate for Microprocessor and is required to selectively license production of pre-miR-17, pre-miR-18a, pre-miR-19a, pre-miR-20a, and pre-miR-19b from this cluster. Two complementary cis-regulatory repression domains within pri-miR-17∼92 are required for the blockade of miRNA processing through the formation of an autoinhibitory RNA conformation. The endonuclease CPSF3 (CPSF73) and the spliceosome-associated ISY1 are responsible for pro-miRNA biogenesis and expression of all miRNAs within the cluster except miR-92. Thus, developmentally regulated pro-miRNA processing is a key step controlling miRNA expression and explains the posttranscriptional control of miR-17∼92 expression in development.

    The involvement of microRNA (miRNAs), a new class of small RNA molecules, in governing angiogenesis has been well described. Our aim was to investigate miRNA-mediated regulation of angiogenesis in a series of familial breast cancers stratified by BRCA1/2 mutational status in BRCA carriers and BRCA non-carriers (BRCAX). Affymetrix GeneChip miRNA Arrays were used to perform miRNA expression analysis on 43 formalin-fixed paraffin-embedded (FFPE) tumour tissue familial breast cancers (22 BRCA 1/2-related and 21 BRCAX). Pathway enrichment analysis was carried out with the DIANA miRPath v2.0 web-based computational tool, and the miRWalk database was used to identify target genes of deregulated miRNAs. An independent set of 8 BRCA 1/2-related and 11 BRCAX breast tumors was used for validation by Real-Time PCR. In vitro analysis on HEK293, MCF-7 and SUM149PT cells were performed to best-clarify miR-573 and miR-578 role. A set of 16 miRNAs differentially expressed between BRCA 1/2-related and BRCAX breast tumors emerged from the profile analysis. Among these, miR-578 and miR-573 were found to be down-regulated in BRCA 1/2-related breast cancer and associated to the Focal adhesion, Vascular Endothelial Growth Factor (VEGF) and Hypoxia Inducible Factor-1 (HIF-1) signaling pathways. Our data highlight the role of miR-578 and miR-573 in controlling BRCA 1/2-related angiogenesis by targeting key regulators of Focal adhesion, VEGF and HIF-1 signaling pathways.

    Sediment cores from Lakes Zurich, Constance, from the Sea of Marmara and from southern Turkey, northern Cyprus and eastern Spain were dated using natural {sup 210}Pb, fallout {sup 137}Cs and cosmic-ray produced {sup 7}Be radionuclides. Constant activity regions in the uppermost sections of sediments from Lake Zurich and the Sea of Marmara were attributed to post-depositional mobility of {sup 210}Pb in the former case and to bioturbation in the latter. A serious discrepancy exists between the {sup 210}Pb dating of Sea of Marmara sediments and those obtained by organic carbon based methods. The elements Zn, Cu, P and Pb were enriched in the upper sections of the sediment cores corresponding to the last 200 years. The increased metallurgical activities as a result of reforms in the Ottoman Army during the 18th century could be the most likely cause. (Author).

    Full Text Available Abstract Background MicroRNAs (miRNAs are ~22 nt long integral elements responsible for post-transcriptional control of gene expressions. After the identification of thousands of miRNAs, the challenge is now to explore their specific biological functions. To this end, it will be greatly helpful to construct a reasonable organization of these miRNAs according to their homologous relationships. Given an established miRNA family system (e.g. the miRBase family organization, this paper addresses the problem of automatically and accurately classifying newly found miRNAs to their corresponding families by supervised learning techniques. Concretely, we propose an effective method, miRFam, which uses only primary information of pre-miRNAs or mature miRNAs and a multiclass SVM, to automatically classify miRNA genes. Results An existing miRNA family system prepared by miRBase was downloaded online. We first employed n-grams to extract features from known precursor sequences, and then trained a multiclass SVM classifier to classify new miRNAs (i.e. their families are unknown. Comparing with miRBase's sequence alignment and manual modification, our study shows that the application of machine learning techniques to miRNA family classification is a general and more effective approach. When the testing dataset contains more than 300 families (each of which holds no less than 5 members, the classification accuracy is around 98%. Even with the entire miRBase15 (1056 families and more than 650 of them hold less than 5 samples, the accuracy surprisingly reaches 90%. Conclusions Based on experimental results, we argue that miRFam is suitable for application as an automated method of family classification, and it is an important supplementary tool to the existing alignment-based small non-coding RNA (sncRNA classification methods, since it only requires primary sequence information. Availability The source code of miRFam, written in C++, is freely and publicly

    The Yellowstone geothermal complex has yielded foundational discoveries that have significantly enhanced our understanding of the Archaea. This study continues on this theme, examining Yellowstone Lake and its lake floor hydrothermal vents. Significant Archaea novelty and diversity were found associated with two near-surface photic zone environments and two vents that varied in their depth, temperature and geochemical profile. Phylogenetic diversity was assessed using 454-FLX sequencing (~51,000 pyrosequencing reads; V1 and V2 regions) and Sanger sequencing of 200 near-full-length polymerase chain reaction (PCR) clones. Automated classifiers (Ribosomal Database Project (RDP) and Greengenes) were problematic for the 454-FLX reads (wrong domain or phylum), although BLAST analysis of the 454-FLX reads against the phylogenetically placed full-length Sanger sequenced PCR clones proved reliable. Most of the archaeal diversity was associated with vents, and as expected there were differences between the vents and the near-surface photic zone samples. Thaumarchaeota dominated all samples: vent-associated organisms corresponded to the largely uncharacterized Marine Group I, and in surface waters, ~69-84% of the 454-FLX reads matched archaeal clones representing organisms that are Nitrosopumilus maritimus-like (96-97% identity). Importance of the lake nitrogen cycling was also suggested by >5% of the alkaline vent phylotypes being closely related to the nitrifier Candidatus Nitrosocaldus yellowstonii. The Euryarchaeota were primarily related to the uncharacterized environmental clones that make up the Deep Sea Euryarchaeal Group or Deep Sea Hydrothermal Vent Group-6. The phylogenetic parallels of Yellowstone Lake archaea to marine microorganisms provide opportunities to examine interesting evolutionary tracks between freshwater and marine lineages.

    Objective To explore the levels of plasma miR⁃205, miR⁃212 and miR⁃429 in ovarian cancer and analyze the re⁃lationship between the above indicators and clinical pathology parameters of ovarian cancer. Methods Plasma samples from 71 ovarian cancer patients before treatment were collected. The real⁃time quantitative RT⁃PCR ( qRT⁃PCR) was used to detect the levels of miR⁃205, miR⁃212 and miR⁃429, and the clinical pathology parameters of ovarian cancer ( age, clinical stage, degree of differentiation, histological type and lymph node metastasis) were collected. The clinical pathology parameters of patients with different levels of miR⁃205, miR⁃212 and miR⁃429 were compared. The receiver operating characteristic curve ( ROC) was employed to analyze the clinical value of plasma miR⁃205, miR⁃212 and miR⁃429 in the diagnosis of ovarian cancer. Meanwhile, the plasma samples from 68 healthy volunteers (healthy control group) and 66 patients with benign ovarian tumor (benign group) were collected as control. Results There were higher levels of miR⁃205 and but lower miR⁃212 and miR⁃429 in ovarian cancer group versus other two groups with signifi⁃cant difference ( P all<0�05) . In ovarian cancer, the level of miR⁃205 was related with age, clinical stage, degree of differentiation and lymph node metastasis, and miR⁃212 was related with clinical stage and degree of differentiation, and miR⁃429 was related with clinical stage and lymph node metastasis ( P all<0�05) . The plasma level of miR⁃205 was negatively correlated with miR⁃212 and miR⁃429 ( r=-0�572、-0�325) , and miR⁃212 was positively correlated with miR⁃429 with statistically significance ( r=0�473,P<0�05) . The AUC, sensitivity and specificity of plasma miR⁃205, miR⁃212 and miR⁃429 in the diagnosis of ovarian cancer were 0�915, 92�1%and 86�2%, 0�944,87�3% and 91�0%, and 0�905, 88�5% and 83�6%.

    Full Text Available Abstract Background Viral hemorrhagic septicemia virus (VHSV is a highly contagious viral disease of fresh and saltwater fish worldwide. VHSV caused several large scale fish kills in the Great Lakes area and has been found in 28 different host species. The emergence of VHS in the Great Lakes began with the isolation of VHSV from a diseased muskellunge (Esox masquinongy caught from Lake St. Clair in 2003. VHSV is a member of the genus Novirhabdovirus, within the family Rhabdoviridae. It has a linear single-stranded, negative-sense RNA genome of approximately 11 kbp, with six genes. VHSV replicates in the cytoplasm and produces six monocistronic mRNAs. The gene order of VHSV is 3'-N-P-M-G-NV-L-5'. This study describes molecular characterization of the Great Lakes VHSV strain (MI03GL, and its phylogenetic relationships with selected European and North American isolates. Results The complete genomic sequences of VHSV-MI03GL strain was determined from cloned cDNA of six overlapping fragments, obtained by RT-PCR amplification of genomic RNA. The complete genome sequence of MI03GL comprises 11,184 nucleotides (GenBank GQ385941 with the gene order of 3'-N-P-M-G-NV-L-5'. These genes are separated by conserved gene junctions, with di-nucleotide gene spacers. The first 4 nucleotides at the termini of the VHSV genome are complementary and identical to other novirhadoviruses genomic termini. Sequence homology and phylogenetic analysis show that the Great Lakes virus is closely related to the Japanese strains JF00Ehi1 (96% and KRRV9822 (95%. Among other novirhabdoviruses, VHSV shares highest sequence homology (62% with snakehead rhabdovirus. Conclusion Phylogenetic tree obtained by comparing 48 glycoprotein gene sequences of different VHSV strains demonstrate that the Great Lakes VHSV is closely related to the North American and Japanese genotype IVa, but forms a distinct genotype IVb, which is clearly different from the three European genotypes.

    MicroRNAs (miRNAs) are a class of non-coding RNAs that regulate gene expression. Identification of total number of miRNAs even in completely sequenced organisms is still an open problem. However, researchers have been using techniques that can predict limited number of miRNA in an organism. In this paper, we have used homology based approach for comparative analysis of miRNA of hexapoda group .We have used Apis mellifera, Bombyx mori, Anopholes gambiae and Drosophila melanogaster miRNA datasets from miRBase repository. We have done pair wise as well as multiple alignments for the available miRNAs in the repository to identify and analyse conserved regions among related species. Unfortunately, to the best of our knowledge, miRNA related literature does not provide in depth analysis of hexapods. We have made an attempt to derive the commonality among the miRNAs and to identify the conserved regions which are still not available in miRNA repositories. The results are good approximation with a small number of mis...

    Full Text Available Myeloid leukemias are highly diverse diseases and have been shown to be associated with microRNA (miRNA expression aberrations. The present study involved an in-depth miRNome analysis of two human acute myeloid leukemia (AML cell lines, HL-60 and THP-1, and one human chronic myeloid leukemia (CML cell line, K562, via massively parallel signature sequencing. mRNA expression profiles of these cell lines that were established previously in our lab facilitated an integrative analysis of miRNA and mRNA expression patterns. miRNA expression profiling followed by differential expression analysis and target prediction suggested numerous miRNA signatures in AML and CML cell lines. Some miRNAs may act as either tumor suppressors or oncomiRs in AML and CML by targeting key genes in AML and CML pathways. Expression patterns of cell type-specific miRNAs could partially reflect the characteristics of K562, HL-60 and THP-1 cell lines, such as actin filament-based processes, responsiveness to stimulus and phagocytic activity. miRNAs may also regulate myeloid differentiation, since they usually suppress differentiation regulators. Our study provides a resource to further investigate the employment of miRNAs in human leukemia subtyping, leukemogenesis and myeloid development. In addition, the distinctive miRNA signatures may be potential candidates for the clinical diagnosis, prognosis and treatment of myeloid leukemias.

    MicroRNAs (miRNAs) are a subtype of small regulatory RNAs that are involved in numerous biological processes through small RNA-induced silencing networks. In an attempt to explore the phylogeny of miRNAs across five platyhelminths, we integrated annotated miRNAs and their full genomes. We identified conserved miRNA clusters and, in particular, miR-71/2 was conserved from planarian to parasitic flatworms and was expanded in free-living Schmidtea mediterranea. Analysis of 22 miRNA loci provided compelling evidence that most known miRNAs are conserved across platyhelminths. Meanwhile, we also observed alterations of known protein-coding genes flanking miRNA(s), such as transcriptional direction conversion and locus relocation, in around ~ 41% of 22 known miRNA loci. Compared with Echinococcus multilocularis, the majority of these events occurred in evolution-distant Hymenolepis microstoma, Schistosoma japonicum or/and S. mediterranea. These results imply rearrangement events occurred near the known miRNA loci.

  11. miR-148 regulates Mitf in melanoma cells.

    Directory of Open Access Journals (Sweden)

    Benedikta S Haflidadóttir

    Full Text Available The Microphthalmia associated transcription factor (Mitf is an important regulator in melanocyte development and has been shown to be involved in melanoma progression. The current model for the role of Mitf in melanoma assumes that the total activity of the protein is tightly regulated in order to secure cell proliferation. Previous research has shown that regulation of Mitf is complex and involves regulation of expression, splicing, protein stability and post-translational modifications. Here we show that microRNAs (miRNAs are also involved in regulating Mitf in melanoma cells. Sequence analysis revealed conserved binding sites for several miRNAs in the Mitf 3'UTR sequence. Furthermore, miR-148 was shown to affect Mitf mRNA expression in melanoma cells through a conserved binding site in the 3'UTR sequence of mouse and human Mitf. In addition we confirm the previously reported effects of miR-137 on Mitf. Other miRNAs, miR-27a, miR-32 and miR-124 which all have conserved binding sites in the Mitf 3'UTR sequence did not have effects on Mitf. Our data show that miR-148 and miR-137 present an additional level of regulating Mitf expression in melanocytes and melanoma cells. Loss of this regulation, either by mutations or by shortening of the 3'UTR sequence, is therefore a likely factor in melanoma formation and/or progression.

    Full Text Available In China, TianMai Xiaoke tablet (TM is used to treat type 2 diabetes. However, the exact mechanism of TM is not clear. This study is to investigate the effect of TM on glucose metabolism in diabetic rats and to identify whether TM takes a direct action through microRNAs on islet. Rats were divided into control group, diabetic group, low dose of TM group (TML, and high dose of TM group (TMH. Pancreas samples were analyzed using microRNA array and Q-PCR. Eight-week treatment with TM significantly decreased fasting blood glucose. The blood glucose was significantly reduced in TM-treated groups before and after oral glucose administration. Fasting insulin and HOMA-IR were suppressed in TM-treated groups. miR-448, let-7b, miR-540, miR-296, miR-880, miR-200a, miR-500, miR-10b, miR-336, miR-30d, miR-208, let-7e, miR-142-5p, miR-874, miR-375, miR-879, miR-501, and miR-188 were upregulated, while miR-301b, miR-134, and miR-652 were downregulated in TMH group. Through target gene analysis and real-time PCR verification, we found that these miRNAs, especially miR-375 and miR-30d, can stimulate insulin secretion in islet. Our data suggest that TM can improve blood glucose in diabetic rats which involved increasing the expression of miR-375 and miR-30d to activate insulin synthesis in islet.

    2016-04-01

    We simulate the seasonal cycle of the Great Lakes' water temperature and lake ice using an idealized coupled lake-atmosphere-ice model. Under identical seasonally varying boundary conditions, this model exhibits more than one seasonally varying equilibrium solutions, which we associate with distinct regional climate regimes. Colder/warmer regimes are characterized by abundant/scarce amounts of wintertime ice and cooler/warmer summer temperatures, respectively. These regimes are also evident in the observations of the Great Lakes' climate variability over recent few decades, and are found to be most pronounced for Lake Superior, the deepest of the Great Lakes, consistent with model predictions. Multiple climate regimes of the Great Lakes also play a crucial role in the accelerated warming of the lakes relative to the surrounding land regions in response to larger-scale global warming. We discuss the physical origin and characteristics of multiple climate regimes over the lakes, as well as their implications for a longer-term regional climate variability.

    Full Text Available The objective of this paper is to determine the likelihood of an algae bloom in a particular lake located in upstate New York. The growth of algae in this lake is caused by a high concentration of phosphorous that diffuses to the surface of the lake. Our calculations, based on Fick's Law, are used to create a mathematical model of the driving force of diffusion for phosphorous. Empirical observations are also used to predict whether the concentration of phosphorous will diffuse to the surface of this lake within a specified time and under specified conditions.

    The epigenetic marks located throughout the genome exhibit great variation between normal and transformed cancer cells. While normal cells contain hypomethylated CpG islands near gene promoters and hypermethylated repetitive DNA, the opposite pattern is observed in cancer cells. Recently, it has been reported that alteration in the microenvironment of melanocyte cells, such as substrate adhesion blockade, results in the selection of anoikis-resistant cells, which have tumorigenic characteristics. Melanoma cells obtained through this model show an altered epigenetic pattern, which represents one of the first events during the melanocytes malignant transformation. Because microRNAs are involved in controlling components of the epigenetic machinery, the aim of this work was to evaluate the potential association between the expression of miR-203, miR-26, and miR-29 family members and the genes Dnmt3a, Dnmt3b, Mecp2, and Ezh2 during cells transformation. Our results show that microRNAs and their validated or predicted targets are inversely expressed, indicating that these molecules are involved in epigenetic reprogramming. We also show that miR-203 downregulates Dnmt3b in mouse melanocyte cells. In addition, treatment with 5-aza-CdR promotes the expression of miR-26 and miR-29 in a nonmetastatic melanoma cell line. Considering the occurrence of CpG islands near the miR-26 and miR-29 promoters, these data suggest that they might be epigenetically regulated in cancer.

    MicroRNAs (miRNA) are noncoding RNAs that regulate multiple cellular processes, including proliferation and apoptosis. We used microarray technology to identify miRNAs that were upregulated by non-small cell lung cancer (NSCLC) A549 cells in response to cisplatin (CDDP). The corresponding synthetic miRNA precursors (pre-miRNAs) per se were not lethal when transfected into A549 cells yet affected cell death induction by CDDP, C2-ceramide, cadmium, etoposide, and mitoxantrone in an inducer-specific fashion. Whereas synthetic miRNA inhibitors (anti-miRNAs) targeting miR-181a and miR-630 failed to modulate the response of A549 to CDDP, pre-miR-181a and pre-miR-630 enhanced and reduced CDDP-triggered cell death, respectively. Pre-miR-181a and pre-miR-630 consistently modulated mitochondrial/postmitochondrial steps of the intrinsic pathway of apoptosis, including Bax oligomerization, mitochondrial transmembrane potential dissipation, and the proteolytic maturation of caspase-9 and caspase-3. In addition, pre-miR-630 blocked early manifestations of the DNA damage response, including the phosphorylation of the ataxia-telangiectasia mutated (ATM) kinase and of two ATM substrates, histone H2AX and p53. Pharmacologic and genetic inhibition of p53 corroborated the hypothesis that pre-miR-630 (but not pre-miR-181a) blocks the upstream signaling pathways that are ignited by DNA damage and converge on p53 activation. Pre-miR-630 arrested A549 cells in the G0-G1 phase of the cell cycle, correlating with increased levels of the cell cycle inhibitor p27(Kip1) as well as with reduced proliferation rates and resulting in greatly diminished sensitivity of A549 cells to the late S-G2-M cell cycle arrest mediated by CDDP. Altogether, these results identify miR-181a and miR-630 as novel modulators of the CDDP response in NSCLC.
