    Full Text Available Abstract Background The care and protection of the estimated 143,000,000 orphaned and abandoned children (OAC worldwide is of great importance to global policy makers and child service providers in low and middle income countries (LMICs, yet little is known about rates of child labour among OAC, what child and caregiver characteristics predict child engagement in work and labour, or when such work infers with schooling. This study examines rates and correlates of child labour among OAC and associations of child labour with schooling in a cohort of OAC in 5 LMICs. Methods The Positive Outcomes for Orphans (POFO study employed a two-stage random sampling survey methodology to identify 1480 single and double orphans and children abandoned by both parents ages 6-12 living in family settings in five LMICs: Cambodia, Ethiopia, India, Kenya, and Tanzania. Regression models examined child and caregiver associations with: any work versus no work; and with working Results The majority of OAC (60.7% engaged in work during the past week, and of those who worked, 17.8% (10.5% of the total sample worked 28 or more hours. More than one-fifth (21.9%; 13% of the total sample met UNICEF's child labour definition. Female OAC and those in good health had increased odds of working. OAC living in rural areas, lower household wealth and caregivers not earning an income were associated with increased child labour. Child labour, but not working fewer than 28 hours per week, was associated with decreased school attendance. Conclusions One in seven OAC in this study were reported to be engaged in child labour. Policy makers and social service providers need to pay close attention to the demands being placed on female OAC, particularly in rural areas and poor households with limited income sources. Programs to promote OAC school attendance may need to focus on the needs of families as well as the OAC.

    HIV counseling and testing (HCT) is critical for children in generalized epidemic settings, but significant shortfalls in coverage persist, notably among orphans and others at disproportionate risk of infection. This study investigates the impact of a home visiting program in South Africa on orphaned and vulnerable children's uptake of HCT. Using propensity score matching, survey data for children receiving home visits from trained community-based care workers were compared to data from children living in similar households that had not yet received home visits (n = 1324). Home visits by community-based care workers increased the odds of a child being tested by 97% (OR = 1.97, 95% CI = 1.34-2.92). The home visitation program had an especially pronounced effect on orphans, more than doubling their odds of being tested (OR = 2.12, 95% CI = 1.00-4.47) compared to orphans living in similar households that did not receive home visits. Orphan status alone had no effect on HCT independent of program exposure, suggesting that the program was uniquely able to increase testing in this subgroup. Results highlight the potential for increasing HCT access among children at high risk through targeted community-based initiatives. PMID:27391993

  3. The prevalence of child-specific utilities in NICE appraisals for paediatric indications: rise of the economic orphans?

    Children are not mini-adults, and thus require studies to be conducted in the population of interest to inform decisions about their care. The paucity of such studies for clinical efficacy lead them to be termed 'therapeutic orphans'. Following the introduction of the 'fourth hurdle' of reimbursement approval on the basis of cost-utility analysis, utility data is now a key requirement for patients to access treatments in England and many other countries. This special report considers whether a paucity of utility valuation studies in children may have made them 'economic orphans' as well and presents results of a review of NICE appraisals as a window on this problem over time.

  4. ORPHANED PROTOSTARS

    International Nuclear Information System (INIS)

    We explore the origin of a population of distant companions (∼1000-5000 AU) to Class I protostellar sources recently found by Connelley and coworkers, who noted that the companion fraction diminished as the sources evolved. Here, we present N-body simulations of unstable triple systems embedded in dense cloud cores. Many companions are ejected into unbound orbits and quickly escape, but others are ejected with insufficient momentum to climb out of the potential well of the cloud core and associated binary. These loosely bound companions reach distances of many thousands of AU before falling back and eventually being ejected into escapes as the cloud cores gradually disappear. We use the term orphans to denote protostellar objects that are dynamically ejected from their placental cloud cores, either escaping or for a time being tenuously bound at large separations. Half of all triple systems are found to disintegrate during the protostellar stage, so if multiple systems are a frequent outcome of the collapse of a cloud core, then orphans should be common. Bound orphans are associated with embedded close protostellar binaries, but escaping orphans can travel as far as ∼0.2 pc during the protostellar phase. The steep climb out of a potential well ensures that orphans are not kinematically distinct from young stars born with a less violent pre-history. The identification of orphans outside their heavily extincted cloud cores will allow the detailed study of protostars high up on their Hayashi tracks at near-infrared and in some cases even at optical wavelengths.

    Full Text Available Introduction. Drugs used for treatment of rare diseases are known worldwide under the term of orphan drugs because pharmaceutical companies have not been interested in ”adopting” them, that is in investing in research, developing and producing these drugs. This kind of policy has been justified by the fact that these drugs are targeted for small markets, that only a small number of patients is available for clinical trials, and that large investments are required for the development of drugs meant to treat diseases whose pathogenesis has not yet been clarified in majority of cases. The aim of this paper is to present previous and present status of orphan drugs in Serbia and other countries. The beginning of orphan drugs development. This problem was first recognized by Congress of the United States of America in January 1983, and when the ”Orphan Drug Act” was passed, it was a turning point in the development of orphan drugs. This law provides pharmaceutical companies with a series of reliefs, both financial ones that allow them to regain funds invested into the research and development and regulatory ones. Seven years of marketing exclusivity, as a type of patent monopoly, is the most important relief that enables companies to make large profits. Conclusion. There are no sufficient funds and institutions to give financial support to the patients. It is therefore necessary to make health professionals much more aware of rare diseases in order to avoid time loss in making the right diagnosis and thus to gain more time to treat rare diseases. The importance of discovery, development and production of orphan drugs lies in the number of patients whose life quality can be improved significantly by administration of these drugs as well as in the number of potential survivals resulting from the treatment with these drugs.

  9. Orphan Care in China

    2009-07-01

    Full Text Available Orphan care in China was once provided by the central government as a means of social control. The centralized welfare delivery guaranteed some of the poorest orphans to be protected by the government. Since the economic reform, the central government started to relinquish its control over social welfare delivery, new forms of orphan care were introduced into China, sharing the responsibilities and burdens for caring the orphans. Yet, many issues and problems exist in social delivery due to a lack of finances, professionals, and policy support. In this chapter, we will discuss the background of social welfare changes in China, as pertains to orphan care, focusing on the different types of orphans as a result of social issues, service delivery, barriers and solutions. It is claimed that during the reform, the burden of orphan care in China may not be reduced in the coming future, and we offer suggestions to cope with that.

    Full Text Available Current public opinion about the residential care system in contemporary Russia is extremely negative. A majority of Russians, both citizens and professionals, consider that family placement is the best arrangement for orphaned children. The year 2007 was announced as the Year of the Child in Russia. The majority of officials interpreted it as the year of de-institutionalization of the residential care system for children in Russia. De-institutionalization is mostly identified as reform focused on family placement instead of placement in institutions. Vladimir Fridlyanov, the executive director of the Ministry of Science and Education, announced in May, 2007 that the government is going to transfer 120,000 children from institutions into families every year from 2007 until 2010 and reduce the number of residential care institutions by one-third (Nesterova 2007. But the likelihood of family placement is small, with the exception of the adoption of infants without serious pathologies, and the attempts of precipitant de-institutionalization (when children’s homes are closed and children are distributed among families have failed (children were returned into children homes. According to the opinion of the Ministry, the key obstacle to effective de-institutionalization is the lack of professionals in adoption and foster care (Vazhdaeva 2006.

  11. Fomepizole (orphan medical).

    Hantson, P

    2001-06-01

    Orphan Medical has developed fomepizole as a potential treatment for both ethylene glycol and methanol poisoning. The drug was launched as Antizol in January 1998 for the treatment of ethylene glycol poisoning [273949] after US marketing approval was grantedin December 1997 [271563]. It has also received US approval for methanol poisoning [393217] and UK approval for ethylene glycol poisoning [329495]. In 1999, Orphan Medical's partner, Cambridge Laboratories, intended to pursue European approval under the mutual recognition procedure [329495]. However, by September 2000, Cambridge Laboratories had discontinued their involvement with fomepizole and IDIS World Medicines had licensed the rights to distribute the drug in the UK [412142]. In February 2000, the Canadian Therapeutic Products Programme (TPP) granted fomepizole Priority Review, provided that an NDA was submitted by March 14, 2000 [354665]. In August 2000, the TPP accepted this NDA and set a target date for approval in the fourth quarter of 2000 [379474]. The TPP granted fomepizole a Notice of Compliance permitting the sale of fomepizole in Canada in December 2000. The company's marketing partner in Canada, Paladin Labs had launched fomepizole by January 2001 [396953]. In June 2000, Tucker Anthony Cleary Gull stated that the Orphan Drug status which Orphan Medical had obtained for fomepizole would provide marketing exclusivity through December 2004. The analysts also stated that fomepizole had accounted for 40% of Orphan Medical's revenue in financial year 1999, although +/- 30% of sales were estimated to be due to stockpiling [409606].

  12. The Detectability of Orphan Afterglows

    2002-01-01

    The realization that GRBs release a rather constant amount of energy implies that the post jet-break afterglow evolution would be rather universal and for a given redshift they should be detected up to a fixed observer angle. We estimate the observed magnitude and the implied detectability of orphan afterglows. We show that orphan afterglows would be detectable only up to rather small ($\\sim 10^o$) angles away from the GRB jet axis. Thus a detection orphan afterglow would generally correspond to a "near-miss" of the GRB whose jet was pointing just slightly away from us. Both theoretical and phenomenological estimates of the rate of orphan afterglows suffer from a rather large uncertainty. With our "canonical" parameters we expect a dozen transients that would arise from orphan GRBs in the SDSS and a comparable number of transients in a dedicated 2M class telescope operating full time in an orphan afterglow search.

    The objective of this study is to analyze policies concerning orphan medicines, used to treat patients suffering from a rare disease. The decisions about orphan designation and marketing authorization of orphan medicines are taken at European level, but each Member State is responsible for decisions regarding reimbursement. The European measures to encourage the development of orphan medicines, such as market exclusivity for a period of ten years, seem to be successful. However, this market exclusivity should be revised once the profitability of such medicines has clearly been demonstrated. Our study recommends the implementation of patient registries at the European level in order to describe the natural evolution of rare diseases and the efficacy of orphan medicines, the majority of which are relatively expensive. In 2008, Belgian social security services reimbursed orphan medicines for an amount of 66 million euro, accounting for more than 5% of the hospital pharmaceutical budget. The reimbursement of an orphan medicine to an individual patient is subject to multiple conditions. Our study recommends that a unique counter within the NIHDI is created which centralizes all reimbursement requests. The reimbursement of an orphan medicine must be linked to the provision of standardized information needed for a patient register. The NIHDI administration could then, in collaboration with external experts, evaluate reimbursement requests and ensure a coherent application of reimbursement criteria. PMID:20183989

  14. Orphan regulations for orphan drug development in India

    2014-01-01

    Full Text Available Through this review article an attempt has been made to put forward the challenges faced by rare disease drug development and the current scenario of orphan drug legislations in India. An orphan drug is a pharmaceutical agent that is used to treat a rare medical condition (viz., glioblastoma multiforme, nocardiosis, Tourette syndrome, etc. Developed countries such as United States (US, Europe, Japan, and Australia have laid down legal framework for combating rare diseases. A path breaking legislation was formulated by the US government way back in 1983, known as "Orphan Drugs Act (ODA." The key purpose of ODA was to incentivize R and D initiatives for such drugs to treat millions of population suffering from "orphan diseases." Though the percentage of patients suffering from "rare diseases" in India is reportedly higher than the world average, unfortunately even today such cases get little help from our government. Indian government should also encourage its domestic pharmaceutical industry to get engaged in research for orphan drugs by putting an "ODA" in place and extending financial support, and regulatory concessions like smaller and shorter clinical trials, without further delay. Thus, India could well-demonstrate that the concept of orphan drugs for orphan diseases is really not orphan in India.

    The need and opportunity to discover therapeutics for rare or orphan diseases are enormous. Due to limited prevalence and/or commercial potential, of the approximately 6000 orphan diseases (defined by the FDA Orphan Drug Act as development is complicated, time-consuming and expensive with extremely low success rates only adds to the low rate of therapeutics available for orphan diseases. An alternative and efficient strategy to boost the discovery of orphan disease therapeutics is to find connections between an existing drug product and orphan disease. Drug Repositioning or Drug Repurposing--finding a new indication for a drug--is one way to maximize the potential of a drug. The advantages of this approach are manifold, but rational drug repositioning for orphan diseases is not trivial and poses several formidable challenges--pharmacologically and computationally. Most of the repositioned drugs currently in the market are the result of serendipity. One reason the connection between drug candidates and their potential new applications are not identified in an earlier or more systematic fashion is that the underlying mechanism 'connecting' them is either very intricate and unknown or indirect or dispersed and buried in an ever-increasing sea of information, much of which is emerging only recently and therefore is not well organized. In this study, we will review some of these issues and the current methodologies adopted or proposed to overcome them and translate chemical and biological discoveries into safe and effective orphan disease therapeutics.

    The definition of a rare disease is not universal and depends on the legislation and policies adopted by each region or country. The main objective of this article is to describe and discuss the legal framework and the regulatory environment of orphan drugs worldwide. Some reflections and discussions on the need for specific orphan drug legislation or policies are described at length. Furthermore, some aspects of the history of each region in respect of the orphan drug legislation evolution are outlined. This article describes and compares the orphan drug legislation or policies of the following countries or regions: United Sates of America (US), European Union (EU), Japan, Australia, Singapore, Taiwan and Canada. The incentives described in the orphan drug legislations or policies, the criteria for designation of orphan status and the authorisation process of an orphan drug are also described and compared. The legislations and policies are to some extent similar but not the same. It is important to understand the main differences among all available legislative systems to improve the international collaboration in the field of orphan drugs and rare diseases.

    Jurčák, J.; Bellot Rubio, L. R.; Sobotka, M.

    2014-04-01

    Aims: We investigate the properties of orphan penumbrae, which are photospheric filamentary structures observed in active regions near polarity inversion lines that resemble the penumbra of regular sunspots but are not connected to any umbra. Methods: We use Hinode data from the Solar Optical Telescope to determine the properties of orphan penumbrae. Spectropolarimetric data are employed to obtain the vector magnetic field and line-of-sight velocities in the photosphere. Magnetograms are used to study the overall evolution of these structures, and G-band and Ca ii H filtergrams are to investigate their brightness and apparent horizontal motions. Results: Orphan penumbrae form between regions of opposite polarity in places with horizontal magnetic fields. Their magnetic configuration is that of Ω-shaped flux ropes. In the two cases studied here, the opposite-polarity regions approach each other with time and the whole structure submerges as the penumbral filaments disappear. Orphan penumbrae are very similar to regular penumbrae, including the existence of strong gas flows. Therefore, they could have a similar origin. The main difference between them is the absence of a "background" magnetic field in orphan penumbrae. This could explain most of the observed differences. Conclusions: The fast flows we detect in orphan penumbrae may be caused by the siphon flow mechanism. Based on the similarities between orphan and regular penumbrae, we propose that the Evershed flow is also a manifestation of siphon flows.

    Strong gravitational lenses are uniquely suited for the study of dark matter structure and substructure within massive halos of many scales, act as gravitational telescopes for distant faint objects, and can give powerful and competitive cosmological constraints. Some 300 lenses have been identified in the literature in one form or another; many others have been found, but perhaps have not warranted dedicated publications. The Orphan Lenses project aims to be a master compilation of all strong gravitational lenses that are known, and a community repository for candidate lenses. A clear and uniform database of basic properties and gravitational lens models is being developed, which will be available online and through a smartphone interactive application. I will present the project, and scientific highlights with this dataset.

    Full Text Available Background India currently has an estimated 220,000 children infected by HIV/AIDS and is home to the largest number of AIDS Orphans only next to South Africa in the world. The pandemic not only deprives Orphans of their rights to enjoy a good or a normal childhood, but it also has deleterious effects on their chances of survival or well-being. Thus the future of these children orphaned by the AIDS epidemic addresses a key social issue. Hence this study was done with the objectives, to assess the Demographic profile, Clinical profile and psycho-social profile of HIV Orphans. Methods A Longitudinal study on 82 HIV orphans in the age group 5 to 15yrs was conducted after obtaining informed consent from their caregivers for duration of one year from at Anti retroviral therapy (ART centre KIMS, Hubli. Clinical profile was assessed by WHO staging of HIV, Child Behavior Checklist (CBCL was used to assess Psycho-Social Profile. Chi-square test, paired t test are the tests of significance for qualitative and quantitative variables respectively. Results Mother to Child was the most common mode of transmission in majority of cases i.e 97%. Among the orphans 60% of them were deprived of mother’s care i.e Double orphans and maternal orphans. Majority of subjects i.e 29 (35.4% were in stage 2 of WHO clinical staging. 27(32.9% were in mild immunosuppression at 350 to 499 Absolute lymphocytic count and CD4% in the range of 20 to 25% in 26(31.7%. A statistically significant increase of psychosocial problem in orphans was observed during the follow-up. Conclusion It can be concluded that during the follow-up Psycho-social problems increased in Orphans significantly.

    Full Text Available Abstract Background The magnitude of the AIDS-orphaned children crisis in sub-Saharan Africa has so overstretched the resource of most families that the collapse of fostering in the sub-region seems imminent (UNICEF, 2003, fueling the need for a complementary/alternative care. This paper examines the probability of the natural mentoring care to ameliorate distress mental health in children orphaned by AIDS. Methods 952 children, mean age about 14 years, from local community schools and child-care centers in Kampala (Uganda and Mafikeng/Klerksdorp (South Africa towns participated in the study. The design has AIDS-orphaned group (n = 373 and two control groups: Other-causes orphaned (n = 287 and non-orphaned (n = 290 children. We use measures of child abuse, depression, social discrimination, anxiety, parental/foster care, self-esteem, and social support to estimate mental health. Natural mentoring care is measured with the Ragins and McFarlin (1990 Mentor Role Instrument as adapted. Results AIDS-orphaned children having a natural mentor showed significant decreased distress mental health factors. Similar evidence was not observed in the control groups. Also being in a natural mentoring relationship inversely related to distress mental health factors in the AIDS-orphaned group, in particular. AIDS-orphaned children who scored high mentoring relationship showed significant lowest distress mental health factors that did those who scored moderate and low mentoring relationship. Conclusions Natural mentoring care seems more beneficial to ameliorate distress mental health in AIDS-orphaned children (many of whom are double-orphans, having no biological parents than in children in the control groups.

    The realization that gamma-ray bursts (GRBs) release a constant amount of energy implies that post-jet-break afterglow evolution is largely universal. For a given redshift, all afterglows should be detected up to a fixed observer angle. We estimate the observed magnitude and the implied detectability of orphan afterglows. We show that for reasonable limiting magnitudes (mlim=25), orphan afterglows will typically be detected from small (~10°) angles away from the GRB jet axis. A detected orphan afterglow generally corresponds to a ``near miss'' of a GRB whose jet is pointing just slightly away from us. With our most optimistic parameters, we expect that 15 orphan afterglows will be recorded in the Sloan Digital Sky Survey, and 35 transients will be recorded in a dedicated 2 m class telescope operating full time for a year in an orphan afterglow search. The rate is smaller by a factor of 15 for our ``canonical'' parameters. We show that for a given facility, an optimal survey should be shallower, covering a larger area, rather than deeper. The limiting magnitude should not be, however, lower than ~23, as in this case, more transients from on-axis GRBs will be discovered than orphan afterglows. About 15% of the transients could be discovered with a second exposure of the same area provided that it follows after 3, 4, and 8 days for mlim=23, 25, and 27, respectively.

    There is an estimated 100,000 children orphaned by AIDS in China, but data on the care arrangement of these orphans are limited. In this study, we examine the relationship between AIDS orphans' care arrangement and their psychosocial well-being among a sample of AIDS orphans in rural China. A total of 296 children who lost both parents to AIDS participated in the study, including 176 in orphanages, 90 in kinship care and 30 in community-based group homes. All participants completed a cross-sectional survey assessing their traumatic symptoms, physical health and schooling. Data reveal that the AIDS orphans in group homes reported the best outcomes in three domains of psychosocial well-being, followed by those in the orphanages and then the kinship care. The differences in psychosocial well-being among the three groups of children persist after controlling for key demographic characteristics. The findings suggest that the appropriate care arrangement for AIDS orphans should be evaluated within the specific social and cultural context where the orphans live. In resource-poor regions or areas stricken hardest by the AIDS epidemic, kinship care may not sufficiently serve the needs of AIDS orphans. Community-based care models, with appropriate government and community support preserving the family style and low child-to-caregiver ratio may constitute an effective and sustainable care model for the best interest of the AIDS orphans in developing countries.

  9. Orphan drugs: expensive yet necessary.

    2015-04-01

    Whether the prices of certain orphan treatments are justified is highly controversial. One argument is that such therapies should not be funded through the public purse or private health plans because a patient with a rare disease requires more than their 'fair share' of a limited health care budget. Orphan medications can also be denied because they fare poorly in the cost-effectiveness assessments of drugs. This paper takes the unusual line that life-saving treatments should be provided regardless of their cost. This contention is based on the Harvard philosopher John Rawls' theory of justice. We offer three rules to limit the use of cost-effectiveness approaches: efficiency assessments should not be deployed (i) when the choice is between an only treatment and no treatment, or to (ii) prioritise between different patients and patient groups. However a well considered cost efficiency calculation may have its place (iii) where a patient has a choice between two or more equally safe and effective treatments. We rebut potential objections to this analysis, and conclude that there has been a tendency to classify appeals for orphan treatments as a minority interest and in conflict with the aims of public health and society at large. Rawls' concept of societal justice shows that a distinction between the individual and society in this context is bogus. The funding of orphan therapies is as much a matter for public health as the funding of treatments for other conditions. Treatment must not be withheld on economic grounds.

    Full Text Available Background: It is generally assumed that orphan status increases the risk to children of a range of negative outcomes. In South Africa, death of parents due to HIV-related illness is contributing to a rapid increase in the prevalence of orphans. This paper presents descriptive data from two South African communities, namely Kopanong, in the Free State and Kanana in the North West province, characterising the differences between orphans (double, maternal and paternal and non-orphans on key criteria of social vulnerability.Objectives: The objective was to obtain a better understanding of how different types of orphans and non-orphans may differ in these key areas as a crucial starting point for addressing the devastating consequences the AIDS epidemic has on these children’s lives. While the study focuses on two specific areas these will provide insight into the general situation of orphans in South Africa.Methods: A cross-sectional census survey was conducted in the two communities of Kopanong, comprising n = 5254 households and Kanana, comprising n = 12 984 households.Results: In Kopanong, 8.2% of children had lost both parents, 19.1% had lost their father and 6.5% their mother only, whilst in Kanana the results were 6.5%, 28.1% and 3.7% respectively. Loss of both parents appeared to have a consistent impact on material need, including access to food, clothing and essential services, whilst loss of a single parent seems to have a more variable impact. At present, there are very few child headed households, but this constitutes a risk in the longer term. Conclusions: Orphans appear to be more vulnerable in terms of material need. Children assessed in this study as being most in need were not accessing adequately many services directed at them. There is a need to extend understanding and measurement of emotional need and abuse.

    Full Text Available Transformative experiences can happen at unexpected times, in unexpected ways. This paper tells the story of how a gift of a goat can lead to the transformation of a life. Many organisations globally are engaged in a struggle to overcome poverty and injustice by providing livestock as a means for transformation. The animals in themselves are not enough for the transformed lives; they can be a valuable starting point. In the Uluguru Mountains in Tanzania, a Tanzanian and a Norwegian together took one such initiative in order to support teen-age orphans, one of the most vulnerable groups in the community who were struggling to survive. As practitioners and researchers, the four authors had been taking part in the development of the Mgeta Orphan Education Foundation (MOEF, which had developed through action learning/action research. Selected students received a goat and training, and the opportunity to join and develop a network of orphans throughout the region. In this article, we discuss the benefits and challenges the orphaned youngsters face when joining the foundation. How do they benefit from having the goat and what are the challenges, how do they learn and how do they contribute to fellow farmers in their communities? We claim that many of the students have experienced transformation, and provide examples to give evidence of this claim. However, the students are not the only ones who are transforming; so are we who, as co-researchers, have had the opportunity to play a role in and witness their efforts.

    2016-01-01

    Orphan-drug sales are rocketing, with revenue expected to total $176 billion annually by 2020. As a share of the industry, orphan drugs now account for close to 15% of all prescription revenue globally (excluding generics) and the sector is set to grow at more than twice the rate (10.5%) of the overall prescription market (4.3%). But this success also equates to costs--borne by individual patients and cash-strapped health systems. Prices for orphan drugs can be 19 times higher than for other medications, hampering access for patients, many of whom are children. With ever more such expensive drugs reaching the market, the situation is becoming unsustainable and putting the survival of the orphan drug legislation itself at risk. Here the authors consider why there has been an increase in orphan drug designations, how orphan drug prices are set and regulated, before discussing proposals for how changes which could save the legislation.

    2014-12-01

    Full Text Available Introduction: Every year, approximately 260,000 children are infected with HIV in low- and middle-income countries. The timely initiation and high level of maintenance of antiretroviral therapy (ART are crucial to reducing the suffering of HIV-positive children. We need to develop a better understanding of the background of children's ART non-adherence because it is not well understood. The purpose of this study is to explore the background related to ART non-adherence, specifically in relation to the orphan status of children in Kigali, Rwanda. Methods: We conducted 19 focus group discussions with a total of 121 caregivers of HIV-positive children in Kigali. The primary data for analysis were verbatim transcripts and socio-demographic data. A content analysis was performed for qualitative data analysis and interpretation. Results: The study found several contextual factors that influenced non-adherence: among double orphans, there was psychological distance between the caregivers and children, whereas economic burden was the primary issue among paternal orphans. The factors promoting adherence also were unique to each orphan status, such as the positive attitude about disclosing serostatus to the child by double orphans’ caregivers, and feelings of guilt about the child's condition among non-orphaned caregivers. Conclusions: Knowledge of orphan status is essential to elucidate the factors influencing ART adherence among HIV-positive children. In this qualitative study, we identified the orphan-related contextual factors that influenced ART adherence. Understanding the social context is important in dealing with the challenges to ART adherence among HIV-positive children.

Cardiovascular diseases and cancer (5.44 of 13.43 million) are the major causes of death in developed countries, while lower respiratory tract infections, human immunodeficiency virus infection/acquired immunodeficiency syndrome, diarrhoeal disease, malaria and tuberculosis (10.88 of 27.12 million) are the major causes of death in developing countries with more than 70% of deaths occurring in children. The majority of approximately 800 million people with other rare diseases, including 100000 children born with thalassaemia annually receive no treatment. There are major ethical dilemmas in dealing with global health issues such as poverty and the treatment of orphan and rare diseases. Of approximately 50000 drugs about 10% are orphan drugs, with annual sales of the latter approaching 100 billion USD. In comparison, the annual revenue in 2009 from the top 12 pharmaceutical companies in Western countries was 445 billion USD and the top drug, atorvastatin, reached 100 billion USD. In the same year, the total government expenditure for health in the developing countries was 410 billion USD with only 6%-7% having been received as aid from developed countries. Drugs cost the National Health Service in the United Kingdom more than 20 billion USD or 10% of the annual health budget.

    International Nuclear Information System (INIS)

    Full text: The problem of orphan sources cannot be left unaddressed due high probability of accidental exposure and use of sources for terrorism. Search of objects of this kind is complex particularly when search territory is large. This requires devices capable of detecting sources, identifying their radionuclide composition, and correlating scan results to geographical coordinates and displaying results on a map. Spectral radiation scanner AT6101C can fulfill the objective of search for gamma and neutron radiation sources, radionuclide composition identification, correlation results to geographical coordinates and displaying results on a map. The scanner consists of gamma radiation scintillation detection unit based on NaI(Tl) crystal, neutron detection unit based on two He3 counters, GPS receiver and portable ruggedized computer. Built-in and application software automates entire scan process, saving all results to memory for further analysis with visual representation of results as spectral information diagrams, count rate profile and gamma radiation dose rates on a geographical map. The scanner informs operator with voice messages on detection of radiation sources, identification result and other events. Scanner detection units and accessories are packed in a backpack. Weighing 7 kg, the scanner is human portable and can be used for scan inside cars. The scanner can also be used for radiation mapping and inspections. (author)

    Full Text Available According to the Regulation (EC N. 141/2000 of the European Parliament and of the Council, rare diseases are life-threatening or chronically debilitating conditions, affecting no more than 5 in 10 000 persons in the European Community. It is estimated that between 6000 to 8000 distinct rare diseases affect up to 6% of the total EU population. Therefore, these conditions can be considered rare if taken individually but they affect a significant proportion of the European population when considered as a single group. Several initiatives have been undertaken at international, European and national level to tackle public health as well as research issues related to the prevention, diagnosis, treatment and surveillance of these diseases. The development of innovative and effective medical products for their diagnosis and treatment is frequently hampered by several factors, including the limited knowledge of their natural history, the difficulties in setting up clinical studies due to the limited numbers of patients affected by a specific disease, the weak interest of sponsors due to the restricted market opportunities. Therefore, incentives and other facilitations have been adopted in many parts of the world, including in the EU, in order to facilitate the development and commercialization of diagnostic tools and treatments devoted to rare diseases. This paper illustrates mainly the European initiatives and will discuss the problematic and controversial aspects surrounding orphan drugs. Finally, activities and measures adopted in Italy are presented.

    Using a shallow, two-color survey carried out with the Dark Energy Camera, we detect the southern, possibly trailing arm of the Orphan Stream. The stream is reliably detected to a declination of $-38^\\circ$, bringing the total known length of the Orphan stream to $108^\\circ$. We find a slight offset or "S" shape in the stream at $\\delta \\simeq -14^\\circ$ that would be consistent with the transition from leading to trailing arms. This coincides with a moderate concentration of $137 \\pm 25$ stars (to $g = 21.6$) that we consider a possible remnant of the Orphan progenitor. The position of this feature is in agreement with previous predictions.

    Full Text Available The hierarchical routing protocol LEACH (Low Energy Adaptive Clustering Hierarchy is referred to as the basic algorithm of distributed c lustering protocols. LEACH allows clusters formation. Each cluster has a leader called Cluster Head (CH. The selection of CHs is made with a probabilistic calculation. It is supposed th at each non-CH node join a cluster and becomes a cluster member. Nevertheless, some CHs ca n be concentrated in a specific part of the network. Thus several sensor nodes cannot reach any CH. As a result, the remaining part of the controlled field will not be covered; some sensor n odes will be outside the network. To solve this problem, we propose O-LEACH (Orphan Low Energy Adap tive Clustering Hierarchy a routing protocol that takes into account the orphan nodes. Indeed, a cluster member will be able to play the role of a gateway which allows the joining of o rphan nodes. If a gateway node has to connect a important number of orphan nodes, thus a sub-cluster is created and the gateway node is considered as a CH’ for connected orphans. As a result, orphan nodes become able to send their data messages to the CH which performs i n turn data aggregation and send aggregated data message to the CH. The WSN applicat ion receives data from the entire network including orphan nodes. The simulation results show that O-LEACH performs b etter than LEACH in terms of connectivity rate, energy, scalability and coverage .

  14. EU orphan regulation--ten years of application.

    2010-01-01

    In April 2000, European Regulation (EC) No 141/2000 on Orphan Medicinal Products, which, following the U.S. example, had been adopted to boost the research, development, and marketing of medicinal products for rare diseases, became effective. Ten years later, figures prove that, with an average of more than 70 orphan designations per year, the European orphan regulation is a success. To date, the key issue is no longer research and development but effective market access. Less than 10% of the orphan designated products are approved for marketing and even less products are actually placed on the European national markets due to pricing and reimbursement obstacles. The article examines the European orphan regime, focusing on its two cornerstones--orphan designation and exclusivity--and highlighting the concepts that are still unclear and the issues that have not yet been addressed. The European Orphan Regulation has been proved to work well, but it would be even more successful if orphan designation was easier and orphan incentives were more attractive. The article concludes on the changes to be made to the European orphan legal regime that would encourage even more the research and development of orphan products. PMID:24479246

    Rare (orphan) diseases are defined as diseases whose prevalence is significantly low. Many of these diseases are diagnosed at childhood by pediatricians. Rare diseases pose many obstacles for health care systems in general and patients specifically. As they are rare, they are less investigated, there is less knowledge about the disease and less professionals specializing in it. Furthermore, as for most diseases there is no specific treatment, diagnosis is not relevant. From industry perspective, as the market potential is small, there is no financial incentive to invest in developing treatments for rare diseases. All the above led patients, researchers and policymakers around the world to legislate specific laws designated to encourage and provide incentives for researchers and for the pharmaceutical industry to develop scientific and clinical knowledge as well as potential treatments for these diseases. The objective of this article is to describe the initiation and current status of public health policy concerning orphan disease and drugs.

    Ether lipids are an emerging class of lipids which have so far not been investigated and understood in every detail. They have important roles as membrane components of e.g. lens, brain and testis, and as mediators such as platelet-activating factor. The metabolic enzymes for biosynthesis and degradation have been investigated to some extent. As most involved enzymes are integral membrane proteins they are tricky to handle in biochemical protocols. The sequence of some ether lipid metabolising enzymes has only recently been reported and other sequences still remain obscure. Defined enzymes without assigned sequence are known as orphan enzymes. One of these enzymes with uncharacterised sequence is plasmanylethanolamine desaturase, a key enzyme for the biosynthesis of one of the most abundant phospholipids in our body, the plasmalogens. This review aims to briefly summarise known functions of ether lipids, give an overview on their metabolism including the most prominent members, platelet-activating factor and the plasmalogens. A special focus is set on the description of orphan enzymes in ether lipid metabolism and on the successful strategies how four previous orphans have recently been assigned a sequence. Only one of these four was characterised by classical protein purification and sequencing, whereas the other three required alternative strategies such as bioinformatic candidate gene selection and recombinant expression or development of an inhibitor and multidimensional metabolic profiling.

  19. Correlating Orphaned Windows Registry Data Structures

    Full Text Available Recently, it has been shown that deleted entries of the Microsoft Windows registry (keys may still reside in the system files once the entries have been deleted from the active database. Investigating the complete keys in context may be extremely important from both a Forensic Investigation point of view and a legal point of view where a lack of context can bring doubt to an argument. In this paper we formalise the registry behaviour and show how a retrieved value may not maintain a relation to the part of the registry it belonged to and hence lose that context. We define registry orphans and elaborate on how they can be created inadvertently during software uninstallation and other system processes. We analyse the orphans and attempt to reconstruct them automatically. We adopt a data mining approach and introduce a set of attributes that can be applied by the forensic investigator to match values to their parents. The heuristics are encoded in a Decision Tree that can discriminate between keys and select those which most likely owned a particular orphan value.

    The debate between pro- and anti-international adoption advocates relies heavily on rhetoric and little on data analysis. To better understand the state of orphans and potential adopters in this debate, we utilize the National Survey of Family Growth (NSFG) and the Demographic and Health Surveys (DHS) to study who adopts internationally and the status of orphaned children in sub-Saharan Africa. According to NSFG data adopters are church going, highly educated, stable families aware of the challenges faced by international adoption, with high rates of infertility and rates of child abuse half the population average. According to the DHS data, orphans in sub-Saharan Africa suffer from significantly higher deprivation, reduced schooling and increased levels of stunting and underweight reported than their cohort. Using this data, we estimate conservatively that that 1 50 000 orphans from our sample of sub-Saharan African countries died from their 5-year birth cohort. Given the large number of families seeking to adopt and the high number of orphan deaths, it seems counterproductive to restrict international adoptions given the significantly lower risks faced by children in adopted families compared with remaining orphaned.

    Using a shallow, two-color survey carried out with the Dark Energy Camera, we detect the southern, possibly trailing arm of the Orphan Stream. The stream is reliably detected to a decl. of ‑38°, bringing the total known length of the Orphan Stream to 108°. We find a slight offset or “S” shape in the stream at δ ≃ ‑14° that would be consistent with the transition from leading to trailing arms. This coincides with a moderate concentration of 137 ± 25 stars (to g = 21.6) that we consider a possible remnant of the Orphan progenitor. The position of this feature is in agreement with previous predictions.

    Adults caring for children in HIV-endemic communities are at risk for poor psychological outcomes. However, we still have a limited understanding of how various HIV impacts--including caregiver's own HIV illness, responsibilities of caring for a child orphaned by AIDS, or both--affect psychological outcomes among caregivers. Furthermore, few studies have explored the relationship between stigma, HIV, and psychological outcomes among caregivers of children in HIV-endemic communities. A cross-sectional survey conducted from 2009 to 2010 assessed anxiety among 2477 caregivers of children in HIV-endemic South Africa. Chi-square tested differences in anxiety among caregivers living with HIV, caregivers of a child orphaned by AIDS, and caregivers affected with both conditions. Multivariate logistic regressions identified whether the relationship between HIV impacts and anxiety remained after controlling for socio-demographic co-factors. Mediation analysis tested the relationship between stigma, HIV, and anxiety. The odds of meeting threshold criteria for clinically relevant anxiety symptoms were two and a half times greater among caregivers living with HIV compared to nonaffected caregivers. The odds of meeting threshold criteria for clinically relevant anxiety symptoms were greatest among caregivers living with HIV and caring for a child orphaned by AIDS. Exposure to AIDS-related stigma partially mediated the relationship between HIV and anxiety. Interventions are needed to address caregiver psychological health, particularly among caregivers affected with both conditions of living with HIV and caring for a child orphaned by AIDS.

  3. Does biological relatedness affect child survival?

    Directory of Open Access Journals (Sweden)

    2003-05-01

    Full Text Available Objective: We studied child survival in Rakai, Uganda where many children are fostered out or orphaned. Methods: Biological relatedness is measured as the average of the Wright's coefficients between each household member and the child. Instrumental variables for fostering include proportion of adult males in household, age and gender of household head. Control variables include SES, religion, polygyny, household size, child age, child birth size, and child HIV status. Results: Presence of both parents in the household increased the odds of survival by 28%. After controlling for the endogeneity of child placement decisions in a multivariate model we found that lower biological relatedness of a child was associated with statistically significant reductions in child survival. The effects of biological relatedness on child survival tend to be stronger for both HIV- and HIV+ children of HIV+ mothers. Conclusions: Reductions in the numbers of close relatives caring for children of HIV+ mothers reduce child survival.

  4. The Orbit of the Orphan Stream

    We use recent SEGUE spectroscopy and SDSS and SEGUE imaging data to measure the sky position, distance, and radial velocities of stars in the tidal debris stream that is commonly referred to as the 'Orphan Stream.' We fit orbital parameters to the data, and find a prograde orbit with an apogalacticon, perigalacticon, and eccentricity of 90 kpc, 16.4 kpc and e = 0.7, respectively. Neither the dwarf galaxy UMa II nor the Complex A gas cloud have velocities consistent with a kinematic association with the Orphan Stream. It is possible that Segue-1 is associated with the Orphan Stream, but no other known Galactic clusters or dwarf galaxies in the Milky Way lie along its orbit. The detected portion of the stream ranges from 19 to 47 kpc from the Sun and is an indicator of the mass interior to these distances. There is a marked increase in the density of Orphan Stream stars near (l, b) = (253{sup o}; 49{sup o}), which could indicate the presence of the progenitor at the edge of the SDSS data. If this is the progenitor, then the detected portion of the Orphan Stream is a leading tidal tail. We find blue horizontal branch (BHB) stars and F turnoff stars associated with the Orphan Stream. The turnoff color is (g-r){sub 0} = 0.22. The BHB stars have a low metallicity of [Fe/H]{sub WBG} = -2.1. The orbit is best fit to a halo potential with a halo plus disk mass of about 2.6 x 10{sup 11} M{sub {circle_dot}}, integrated to 60 kpc from the Galactic center. Our fits are done to orbits rather than full N-body simulations; we show that if N-body simulations are used, the inferred mass of the galaxy would be slightly smaller. Our best fit is found with a logarithmic halo speed of v{sub halo} = 73 {+-} 24 km s{sup -1}, a disk+bulge mass of M(R < 60 kpc) = 1.3 x 10{sup 11} M{sub {circle_dot}}, and a halo mass of M(R < 60 kpc) = 1.4 x 10{sup 11} M{sub {circle_dot}}. However, we can find similar fits to the data that use an NFW halo profile, or that have smaller disk masses

    A growing body of evidence suggests that a subset of orphan nuclear receptors are amplified and prognostic for some human cancers. However, the specific roles of these orphan nuclear receptors in tumor progression and their utility as drug targets are not fully understood. In this review, we summarize recent progress in elucidating the direct and indirect involvement of orphan nuclear receptors in cancer as well as their therapeutic potential in a variety of human cancers. Furthermore, we contrast the role of orphan nuclear receptors in cancer with the known roles of estrogen receptor and androgen receptor in hormone-dependent cancers. PMID:24215441

  7. Correlates of poor health among orphans and abandoned children in less wealthy countries: the importance of caregiver health.

    Directory of Open Access Journals (Sweden)

    Nathan Thielman

    Full Text Available BACKGROUND: More than 153 million children worldwide have been orphaned by the loss of one or both parents, and millions more have been abandoned. We investigated relationships between the health of orphaned and abandoned children (OAC and child, caregiver, and household characteristics among randomly selected OAC in five countries. METHODOLOGY: Using a two-stage random sampling strategy in 6 study areas in Cambodia, Ethiopia, India, Kenya, and Tanzania, the Positive Outcomes for Orphans (POFO study identified 1,480 community-living OAC ages 6 to 12. Detailed interviews were conducted with 1,305 primary caregivers at baseline and after 6 and 12 months. Multivariable logistic regression models describe associations between the characteristics of children, caregivers, and households and child health outcomes: fair or poor child health; fever, cough, or diarrhea within the past two weeks; illness in the past 6 months; and fair or poor health on at least two assessments. PRINCIPAL FINDINGS: Across the six study areas, 23% of OAC were reported to be in fair or poor health; 19%, 18%, and 2% had fever, cough, or diarrhea, respectively, within the past two weeks; 55% had illnesses within the past 6 months; and 23% were in fair or poor health on at least two assessments. Female gender, suspected HIV infection, experiences of potentially traumatic events, including the loss of both parents, urban residence, eating fewer than 3 meals per day, and low caregiver involvement were associated with poorer child health outcomes. Particularly strong associations were observed between child health measures and the health of their primary caregivers. CONCLUSIONS: Poor caregiver health is a strong signal for poor health of OAC. Strategies to support OAC should target the caregiver-child dyad. Steps to ensure food security, foster gender equality, and prevent and treat traumatic events are needed.

    The Orphan Drug Act has fostered drug development for patients with rare cancers and other diseases; however, current data suggest that companies are gaming the system to use the law for mainstream drugs. We identify a pattern of pharmaceutical companies submitting drugs to the Food and Drug Administration (FDA) as orphan drugs but once approved, the drugs are used broadly off-label with the lucrative orphan drug protections and exclusivity benefits. Since the law was passed, the proportion of new FDA-approved drugs that were submitted as orphan drugs has increased with a peak last year of 41% of all FDA-approved drugs approved as orphan drugs. On the basis of the current data, we suggest that patients with rare cancers and other diseases may suffer due to dilution of the incentives and benefits. We propose reform to increase submission scrutiny, decrease benefits based on off-label use, and increase price transparency. PMID:26580246

  20. Orphan Stars Found in Long Galaxy Tail

    Science.gov (United States)

    2007-09-01

    Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought. The comet-like tail was observed in X-ray light with NASA's Chandra X-ray Observatory and in optical light with the Southern Astrophysical Research (SOAR) telescope in Chile. The feature extends for more than 200,000 light years and was created as gas was stripped from a galaxy called ESO 137-001 that is plunging toward the center of Abell 3627, a giant cluster of galaxies. "This is one of the longest tails like this we have ever seen," said Ming Sun of Michigan State University, who led the study. "And, it turns out that this is a giant wake of creation, not of destruction." Chandra X-ray Image of ESO 137-001 and Tail in Abell 3627 Chandra X-ray Image of ESO 137-001 and Tail in Abell 3627 The observations indicate that the gas in the tail has formed millions of stars. Because the large amounts of gas and dust needed to form stars are typically found only within galaxies, astronomers have previously thought it unlikely that large numbers of stars would form outside a galaxy. "This isn't the first time that stars have been seen to form between galaxies," said team member Megan Donahue, also of MSU. "But the number of stars forming here is unprecedented." The evidence for star formation in this tail includes 29 regions of ionized hydrogen glowing in optical light, thought to be from newly formed stars. These regions are all downstream of the galaxy, located in or near the tail. Two Chandra X-ray sources are near these regions, another indication of star formation activity. The researchers believe the orphan stars formed within the last 10 million years or so. The stars in the tail of this fast-moving galaxy, which is some 220 million light years away, would be much more isolated than the vast majority of stars in galaxies. H-alpha Image of

    2011-01-01

    Full Text Available Abstract Background AIDS has created new vulnerabilities for rural African households due to prime-age adult mortality and is assumed to lead to impairment of the intergenerational transfer of farming knowledge. There has been scant research to date, however, on the impacts of parental death on farming knowledge of children made orphans by AIDS. The question we investigate is if there is a difference in agricultural expertise between AIDS affected and non-affected adults and children. Methods The research was carried out in rural Benin with 77 informants randomly selected according to their AIDS status: 13 affected and 13 non-affected adults; 13 paternal, 13 maternal and 13 double orphans; and 12 non-orphan children. Informants descriptions from pile sorting exercises of maize and cowpea pests were categorized and then aggregated into descriptions based form (morphology and function (utility and used to determine whether the moving from novice to expert is impaired by children orphaned by AIDS. Differences and similarities in responses were determined using the Fischer exact test and the Cochran-Mantzel-Haenszel test. Results No significant differences were found between AIDS affected and non-affected adults. Results of the study do reveal differences in the use of form and function descriptors among the children. There is a statistically significant difference in the use of form descriptors between one-parent orphans and non-orphans and in descriptors of specific damages to maize. One-parent paternal orphans were exactly like non-affected adults in their 50/50 balanced expertise in the use of both form and function descriptors. One-parent orphans also had the highest number of descriptors used by children overall and these descriptors are spread across the various aspects of the knowledge domain relative to non-orphans. Conclusions Rather than a knowledge loss for one-parent orphans, particularly paternal orphans, we believe we are witnessing

    Full Text Available Objective In Haiti, families were torn apart and children were left orphans after the 2010 earthquake. In the aftermath of this natural disaster many children were relocated to orphanages across the country and adopted internationally. Years later these children find themselves catching up in growth physically, mentally and emotionally after an extremely traumatic event during a crucial time in their health development. Another important marker of development is the primary dentition and the presence of caries.  We report estimates of early childhood caries (ECC frequency, risk factors and quality of health among Haitian children. Methods Medical and dental professionals conducted a descriptive cross sectional study through the Pittsburgh Kids Foundation and their partnership with IDADEE children’s home, EBAC orphanage and New Vision Children’s home. Vital signs were taken and recorded to create a health/growth history for each child. Brief dental screenings were conducted and topical fluoride treatments were administered. Risk factors and quality of health information was obtained from discussions with the caregivers present. The children and caregivers were given oral hygiene education and supplies (i.e. toothbrushes, toothpaste, floss.  Results Physical exams and dental screenings were conducted on the 40 children ages 3-10 years of age living in the IDADEE children’s home. Two children had cavitated teeth. Eight children had teeth that were stained. Four children had evidence of dental trauma. 26 out of the 40 children had otherwise healthy dentition. Conclusion The IDADEE children’s home and New Vision Children’s home have hopes to expand their capacity with new construction scheduled to be finished in 2016. As more children enter these homes action is needed to educate caregivers on ways to identify high-risk children to prevent ECC and ways they can be treated before irreversible damage is done to the developing permanent

    Full Text Available The aim of this study was to determine the impact of the domestic care environment on the prevalence of potentially traumatic events (PTEs and posttraumatic stress disorder (PTSD among orphaned and separated children in Uasin Gishu County, western Kenya.A total of 1565 (55.5% male orphaned and separated adolescents aged 10-18 years (mean 13.8 years, sd 2.2, were assessed for PTSD and PTEs including bullying, physical abuse and sexual abuse. In this sample, 746 lived in extended family households, 746 in Charitable Children's Institutions (CCIs, and 73 on the street. Posttraumatic stress symptom (PTSS scores and PTSD were assessed using the Child PTSD Checklist.Bullying was the commonest PTE in all domestic care environments, followed by physical and sexual abuse. All PTEs were commonest among the street youth followed by CCIs. However, sexual abuse was more prevalent in households than in CCIs. Prevalence of PTSD was highest among street youth (28.8%, then households (15.0% and CCIs (11.5%. PTSS scores were also highest among street youth, followed by CCIs and households. Bullying was associated with higher PTSS scores and PTSD odds than either sexual or physical abuse.This study demonstrated differences in distribution of trauma and PTSD among orphaned and separated children in different domestic care environments, with street youth suffering more than those in CCIs or households. Interventions are needed to address bullying and sexual abuse, especially in extended family households. Street youth, a heretofore neglected population, are urgently in need of dedicated mental health services and support.

    2013-07-01

    Full Text Available This study sought to establish the economic and psychological effects of HIV and AIDS on orphaned boys’ education in primary schools in Nairobi East District, Kenya. Adler’s theory of Individual Psychology as cited in Sherman and Dinkmeyer formed the theoretical framework for the study. Descriptive survey research design was adopted for the study. A total of 200 pupils and 40 teachers formed the study sample. Data was collected using the questionnaire and interview schedules. Data was analyzed using descriptive statistics. The study established that the guardians are not economically able to cater for all the orphans’ needs and this makes the orphans look for alternative ways of catering for their needs by being partially employed or fully employed leading to child labour. Missing their basic needs leads these orphans to be affected psychologically leading to poor performance, absenteeism, and truancy and later drop out of school and may join the street children. It was recommended that the community should be trained and educated on capacity building and reproductive health and helped to design and implement economic projects and programmes to uplift their standard.

    2013-07-01

    Full Text Available We present the study results of psychological characteristics of adolescent orphans living outside the family and having a violation of socialization at the micro level. It was assumed that children experiencing total maternal deprivation from birth, have difficulties in adapting to life. It was revealed that in this group of adolescents the level of motivational tendencies is higher, reflecting a fear of rejection, and the level of suspicion. They are more than their peers convinced that other people are plotting something evil and can cause harm to demonstrate high degree of irritability, ready to show negative feelings at the slightest excitation (short temper, rudeness, stress, anger. These features are important to understand by specialists to create an educational system that allows to correct the negative aspects, prepare the child for substitute family, provide support and maintenance for a period of adaptation, to help prospective parents.

  7. Implementation of oral health education to orphan children

    International Nuclear Information System (INIS)

    To determine the knowledge and oral hygiene status of orphange children in apune and a changes in them after health education. Study Design: Interventional study. Place and Duration of Study: Centers for Orphan Children in Pune, India, from April to June 2014. Methodology: A specially designed questionnaire was used to assess the dental problems and existing oral hygiene maintenance practice among children between 5 - 12 years of age (n=100) in an orphanage center. Pre- and post interventional intra-oral examination was carried out to check their oral hygiene status which included DMFS (Decayed Missing Filled Tooth Surfaces index (for permanent teeth)), OHIS (Simplified Oral Hygiene Index) and gingival indices. Intervention was in the form of oral health education, demonstration of correct brushing technique, diet counselling and maintenance of overall oral hygiene. Results: Present study shows that the orphans had multiple dental problems along with improper oral hygiene practices and careless attitude towards oral health. Pre- and post-interventional DMFS was compared using Wilcoxon sign rank test, which was not significant; while OHIS and gingival indices were compared by using repeat measures ANOVA(p < 0.001) which was significant for each, respectively. Conclusion: There was considerable improvement in the oral hygiene status of orphans due to educational intervention. Oral health education at right age can help to cultivate healthy oral hygiene practices in orphans which will benefit them for lifelong. Caretakers should be educated and trained about oral hygiene practices so that they can implement it and supervise the orphan children. (author)

    Marketing authorization application dossiers of 17 orphan drugs (ODs) and 51 non-ODs evaluated by the European Medicines Agency (EMA) in the period 2009-2010 were compared. We aimed to identify whether any differences existed between ODs and non-ODs in number and type of deficits brought forward during the EMA review, regarding the clinical development plan, clinical outcome and medical need and studied whether these deficits were similarly associated with marketing approval in the EU. In 71% of the ODs dossiers and 65% of the non-ODs dossiers marketing approval was granted. Differences in deficits were found, but similarities in the way ODs and non-ODs were reviewed and marketing approval decisions were taken, underline that regulatory standards are equally high.

    Low sample size and high variation within populations reduce power of statistical tests. These aspects of statistical power appear to have affected an analysis comparing overwinter survival rates of non-orphan and orphan Caribou (Rangifer tarandus) calves by an earlier study for the Porcupine Caribou Herd. A re-evaluation of the data revealed that conclusions about a lack of significant difference in the overwinter survival rates between orphan and non-orphan calves were premature.

  10. Evolution of an Orphaned Source Management Strategy: Canadian Experience

    International Nuclear Information System (INIS)

    During the course of providing regulatory control over nuclear substances, the Canadian Nuclear Safety Commission (CNSC) from time to time has identified sources without an owner or a responsible party. In 2011, after completing a review of its regulatory oversight with respect to orphan sources, the CNSC put in place a strategy that is based on promotion and communication, prevention, and response and recovery of orphan sources. The paper describes the challenges that have occurred during the development of the strategy and the lessons learned during the implementation phase. (author)

    The Orphan Drug Act of 1983 established incentives for the development of drugs that treat rare, or orphan, diseases. We used the IMS Health MIDAS database of audited biopharmaceutical sales to measure US annual spending on orphan drugs in the period 2007-13, and we estimated spending on the drugs for the period 2014-18. We identified 356 brand-name orphan drugs that were approved by the Food and Drug Administration in the period 1983-2013. While we included orphan drugs with both orphan and other indications, we adjusted spending to include only spending for orphan indications. In 2014 dollars, expenditures on orphan drugs totaled $15 billion in 2007 and $30 billion in 2013-representing 4.8 percent and 8.9 percent of total pharmaceutical expenditures, respectively. Our future trend analysis for the period 2014-18 suggests a slowing in the growth of orphan drug expenditures. The overall impact of orphan drugs on payers' drug budgets is relatively small, and spending on orphan drugs as a percentage of total pharmaceutical expenditures has remained fairly stable. Concerns that growth in orphan drug expenditures may lead to unsustainable drug expenditures do not appear to be justified. PMID:27605637

  17. The importance of HIV prevention messaging for orphaned youth in Zimbabwe.

    Haney, Erica; Singh, Kavita

    2012-01-01

    The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Female adolescent orphans are particularly in jeopardy of contracting HIV due to disadvantages including extreme poverty, low education, and the absent of parental oversight which can lead to higher risk-taking sexual behaviors. By understanding where girls receive education about HIV and who they rely on for information, organizations can effectively modify existing programs to better target this at-risk population. For this study a household survey was conducted which included 216 orphans and 324 non-orphans (n=540), aged 12-17 years, in the resource-poor setting of Hwange District, Zimbabwe. The aims of this article were to examine the differences between orphans and non-orphans in HIV prevention message exposure, level of motivation for learning about HIV, and communication with caregivers about safe sex. The household survey revealed that younger orphans, aged 12-15 years, were more motivated to learn about HIV and had greater HIV messaging exposure in school than non-orphans. These exposure and differences in the levels of motivation between groups dissipated at older ages. Our research also discovered less caregiver communication among orphans than non-orphans. Our findings suggest that HIV programs targeting orphans need to do a better job at keeping older orphans interested in HIV prevention at a time when it matters most. Furthermore, intervention strategies that provide caregiver support are instrumental in effectively delivering prevention messages to girls at home. PMID:22293040

  5. Psychological health of orphan bonobos and chimpanzees in African sanctuaries.

    Directory of Open Access Journals (Sweden)

    Victoria Wobber

    Full Text Available BACKGROUND: Facilities across Africa care for apes orphaned by the trade for "bushmeat." These facilities, called sanctuaries, provide housing for apes such as bonobos (Pan paniscus and chimpanzees (Pan troglodytes who have been illegally taken from the wild and sold as pets. Although these circumstances are undoubtedly stressful for the apes, most individuals arrive at the sanctuaries as infants and are subsequently provided with rich physical and social environments that can facilitate the expression of species-typical behaviors. METHODS AND FINDINGS: We tested whether bonobo and chimpanzee orphans living in sanctuaries show any behavioral, physiological, or cognitive abnormalities relative to other individuals in captivity as a result of the early-life stress they experience. Orphans showed lower levels of aberrant behaviors, similar levels of average cortisol, and highly similar performances on a broad battery of cognitive tests in comparisons with individuals of the same species who were either living at a zoo or were reared by their mothers at the sanctuaries. CONCLUSION: Taken together, these results support the rehabilitation strategy used by sanctuaries in the Pan-African Sanctuary Alliance (PASA and suggest that the orphans we examined did not show long-term signs of stress as a result of their capture. Our findings also show that sanctuary apes are as psychologically healthy as apes in other captive settings and thus represent a valuable resource for non-invasive research.

  9. Pricing and reimbursement of orphan drugs: the need for more transparency

    Directory of Open Access Journals (Sweden)

    Simoens Steven

    2011-06-01

    Full Text Available Abstract Pricing and reimbursement of orphan drugs are an issue of high priority for policy makers, legislators, health care professionals, industry leaders, academics and patients. This study aims to conduct a literature review to provide insight into the drivers of orphan drug pricing and reimbursement. Although orphan drug pricing follows the same economic logic as drug pricing in general, the monopolistic power of orphan drugs results in high prices: a orphan drugs benefit from a period of marketing exclusivity; b few alternative health technologies are available; c third-party payers and patients have limited negotiating power; d manufacturers attempt to maximise orphan drug prices within the constraints of domestic pricing and reimbursement policies; and e substantial R&D costs need to be recouped from a small number of patients. Although these conditions apply to some orphan drugs, they do not apply to all orphan drugs. Indeed, the small number of patients treated with an orphan drug and the limited economic viability of orphan drugs can be questioned in a number of cases. Additionally, manufacturers have an incentive to game the system by artificially creating monopolistic market conditions. Given their high price for an often modest effectiveness, orphan drugs are unlikely to provide value for money. However, additional criteria are used to inform reimbursement decisions in some countries. These criteria may include: the seriousness of the disease; the availability of other therapies to treat the disease; and the cost to the patient if the medicine is not reimbursed. Therefore, the maximum cost per unit of outcome that a health care payer is willing to pay for a drug could be set higher for orphan drugs to which society attaches a high social value. There is a need for a transparent and evidence-based approach towards orphan drug pricing and reimbursement. Such an approach should be targeted at demonstrating the relative effectiveness

  10. Orphan neuropeptides. Novel neuropeptides modulating sleep or feeding.

    Science.gov (United States)

    Chung, Shinjae; Civelli, Olivier

    2006-08-01

    Neuropeptides form the largest family of modulators of synaptic transmission. Until 1995 some 60 different neuropeptides had been found. With the recognition that all neuropeptides act by binding to G protein coupled receptors (GPCRs), a new approach relying on the use of orphan GPCRs as targets was designed to identify novel neuropeptides. Thirteen new neuropeptide families have since been discovered. In this review we will describe the orphan GPCR-based approach that led to these discoveries and present its impact on two specific physiological responses, feeding and sleep. In particular, we will discuss the modulatory roles of the hypocretins/orexins and of neuropeptide S in sleep and awakening and those of ghrelin and melanin concentrating hormone in food intake.

    We show that, under mild conditions on the underlying metric, duals of appropriately defined anisotropic Voronoi diagrams are embedded triangulations. Furthermore, they always triangulate the convex hull of the vertices, and have other properties that parallel those of ordinary Delaunay triangulations. These results apply to the duals of anisotropic Voronoi diagrams of any set of vertices, so long as the diagram is orphan-free.

    This project involves analyzing data directly off the footprint of the Sloan Digital Sky Survey in order to find the progenitor of the Orphan tidal stream. This stream of stellar debris, known to span distances 20 to 47 kpc from the Sun, is believed to be the remnants of a small dwarf galaxy that is largely disrupted. Images were obtained in the vicinity of this stream from the MOSAIC1.1 camera on the 4-meter Mayall telescope at the Kitt Peak National Observatory. The region observed covers 11 square degrees of sky, approximately 7 square degrees of which have no SDSS data. The area outside the SDSS was selected to explore the increase in density of Orphan stars in this location, discussed in Newberg et al. 2010. The positions and magnitudes of stars outside of the SDSS were calculated and calibrated with both data from the SDSS itself, as well as the USNOB-1 catalog. The resulting Orphan candidates selected from this catalog were used to explore the stellar densities along this stream, providing insight into the nature of its progenitor. This research was supported by NSF grant AST 09-37523.

    2016-05-01

    Aims: The formation and evolution of an Hα filament in active region (AR) 10953 is described. Methods: Observations from the Solar Optical Telescope (SOT) aboard the Hinode satellite starting from UT 18:09 on 27th April 2007 until UT 06:08 on 1st May 2007 were analysed. 20 scans of the 6302 Å Fe I line pair recorded by SOT/SP were inverted using the spatially coupled version of the SPINOR code. The inversions were analysed together with co-spatial SOT/BFI G-band and Ca II H and SOT/NFI Hα observations. Results: Following the disappearance of an initial Hα filament aligned along the polarity inversion line (PIL) of the AR, a new Hα filament formed in its place some 20 h later, which remained stable for, at least, another 1.5 days. The creation of the new Hα filament was driven by the ascent of horizontal magnetic fields from the photosphere into the chromosphere at three separate locations along the PIL. The magnetic fields at two of these locations were situated directly underneath the initial Hα filament and formed orphan penumbrae already aligned along the Hα filament channel. The 700 G orphan penumbrae were stable and trapped in the photosphere until the disappearance of the overlying initial Hα filament, after which they started to ascend into the chromosphere at 10 ± 5 m/s. Each ascent was associated with a simultaneous magnetic flux reduction of up to 50% in the photosphere. The ascended orphan penumbrae formed dark seed structures in Hα in parallel with the PIL, which elongated and merged to form an Hα filament. The filament channel featured horizontal magnetic fields of on average 260 G at log (τ) = -2 suspended above the nearly field-free lower photosphere. The fields took on an overall inverse configuration at log (τ) = -2 suggesting a flux rope topology for the new Hα filament. The destruction of the initial Hα filament was likely caused by the flux emergence at the third location along the PIL. Conclusions: We present a new

  17. Significant Comparative Characteristics between Orphan and Nonorphan Genes in the Rice (Oryza sativa L. Genome

    Directory of Open Access Journals (Sweden)

    Wen-Jiu Guo

    2007-01-01

    Full Text Available Microsatellites are short tandem repeats of one to six bases in genomic DNA. As microsatellites are highly polymorphic and play a vital role in gene function and recombination, they are an attractive subject for research in evolution and in the genetics and breeding of animals and plants. Orphan genes have no known homologs in existing databases. Using bioinformatic computation and statistical analysis, we identified 19,26 orphan genes in the rice (Oryza sativa ssp. Japanica cv. Nipponbare proteome. We found that a larger proportion of orphan genes are expressed after sexual maturation and under environmental pressure than nonorphan genes. Orphan genes generally have shorter protein lengths and intron size, and are faster evolving. Additionally, orphan genes have fewer PROSITE patterns with larger pattern sizes than those in nonorphan genes. The average microsatellite content and the percentage of trinucleotide repeats in orphan genes are also significantly higher than in nonorphan genes. Microsatellites are found less often in PROSITE patterns in orphan genes. Taken together, these orphan gene characteristics suggest that microsatellites play an important role in orphan gene evolution and expression.

    2010-08-01

    Full Text Available Abstract Background In the face of the HIV/AIDS epidemic that has contributed to the dramatic increase in orphans and abandoned children (OAC worldwide, caregiver attitudes about HIV, and HIV-related stigma, are two attributes that may affect caregiving. Little research has considered the relationship between caregiver attributes and caregiver-reported HIV-related stigma. In light of the paucity of this literature, this paper will describe HIV-related stigma among caregivers of OAC in five less wealthy nations. Methods Baseline data were collected between May 2006 through February 2008. The sample included 1,480 community-based and 192 institution-based caregivers. Characteristics of the community-based and institution-based caregivers are described using means and standard deviations for continuous variables or counts and percentages for categorical variables. We fit logistic regression models, both for the full sample and separately for community-based and institution-based caregivers, to explore predictors of acceptance of HIV. Results Approximately 80% of both community-based and institution-based caregivers were female; and 84% of institution-based caregivers, compared to 66% of community-based caregivers, said that they would be willing to care for a relative with HIV. Similar proportions were reported when caregivers were asked if they were willing to let their child play with an HIV-infected child. In a multivariable model predicting willingness to care for an HIV-infected relative, adjusted for site fixed effects, being an institution-based caregiver was associated with greater willingness (less stigma than community-based caregivers. Decreased willingness was reported by older respondents, while willingness increased with greater formal education. In the adjusted models predicting willingness to allow one's child to play with an HIV-infected child, female gender and older age was associated with less willingness. However, willingness

    This study was designed to test the feasibility and child clinical outcomes for group-based trauma-focused cognitive behavior therapy (TF-CBT) for orphaned children in Tanzania. There were 64 children with at least mild symptoms of grief and/or traumatic stress and their guardians who participated in this open trial. The TF-CBT for Child Traumatic Grief protocol was adapted for use with a group, resulting in 12 weekly sessions for children and guardians separately with conjoint activities and 3 individual visits with child and guardian. Using a task-sharing approach, the intervention was delivered by lay counselors with no prior mental health experience. Primary child outcomes assessed were symptoms of grief and posttraumatic stress (PTS); secondary outcomes included symptoms of depression and overall behavioral adjustment. All assessments were conducted pretreatment, posttreatment, and 3 and 12 months after the end of treatment. Results showed improved scores on all outcomes posttreatment, sustained at 3 and 12 months. Effect sizes (Cohen's d) for baseline to posttreatment were 1.36 for child reported grief symptoms, 1.87 for child-reported PTS, and 1.15 for guardian report of child PTS.

However, at least 40% of the gene products in newly sequenced genomes typically remain uncharacterised. Proteins without an annotated function are also known...... as orphan proteins since they do not belong to a functionally characterised protein family. Many sequences must, therefore, be compared using their features rather than by direct comparison in the conventional sequence space. Here we focus on one such feature — glycosylation — that is common in eukaryotic...

    One impact of incurable HIV infection is the large number of orphans and vulnerable children (OVC) who are affected by HIV. The age-based criteria used to determine support eligibility for HIV orphans, however, exclude older orphans (≥18 years of age) from support. We conducted a literature survey in order to explore possible inclusion of older orphans (ages 18-24 years) in HIV orphanhood research. We found 17 studies conducted in eight countries that met the review inclusion criteria. Findings from the review revealed that older HIV orphans are underrepresented in the OVC literature. The emerging, but limited, evidence suggests that older orphans are at risk for poorer psychosocial and reproductive outcomes. We recommend increasing inclusion of older orphans in HIV orphan research because of their complex physical, reproductive, and psychosocial needs. This inclusion is necessary to allow their experiences and needs to become clearer. PMID:26482073

In the early postwar years, financial status of children's institutions in the Kuban region in comparison with the military over the years has improved somewhat. Funding for children's homes was carried out in full, improved nutrition students. Despite the presence of local constraints on material maintenance of children's homes. In general, the existing system of social protection of orphans has fulfilled its function in the short term has been eliminated homeless children throughout the territory of Krasnodar region. The article shows the role of the party and government bodies in ensuring the conditions for the functioning of orphanages. For the opening theme used a variety of sources, some of which are introduced into scientific circulation for the first time.

    The use of biomarkers within the procedures of the Committee of Orphan Medicinal Products (COMP) of the European Medicines Agency (EMA) is discussed herein. The applications for Orphan Medicinal Product designation in the EU are evaluated at two stages. At the time of orphan designation application, the file undergoes an assessment to establish whether the proposed condition is a distinct and serious condition affecting not more than 5 in 10,000 people in the EU, and whether the product is plausible as a therapy for that condition. In cases where therapies already exist, the significant benefit of the candidate product over existing therapies is also evaluated. The orphan criteria are reassessed at the time of marketing authorisation, so that marketing exclusivity for the product in the orphan medical condition can be granted. Within this context, biomarkers have been used in submissions in order to define an orphan condition and to justify that the criteria for orphan designation are met. The current work discusses specific examples from the experience of the COMP, where biomarkers have played a decisive role. Importantly, it identifies the proposal of sub-sets of non-rare conditions based on biomarkers as a challenging issue in the evaluation of applications. In particular two specific requirements for the candidate orphan medicines in relation to the biomarker-based subsets are highlighted: the "plausible link to the condition" and the "exclusion of effects outside the subset".

    Full Text Available Background: Research has shown that orphans in sub-Saharan Africa are at increased risk for mental health problems. Exposure to maltreatment and HIV/AIDS-related stigmatization are related to orphans’ psychological distress. Yet, researchers stress the need for more research in low-income countries to identify which factors of being an orphan may lead to psychological distress. Objectives: The present study aims to systematically investigate orphans’ experiences of maltreatment and stigmatization to identify factors that relate to their psychological distress. Methods: In total, 89 Tanzanian children who had lost at least one parent were compared to 89 matched non-orphans (mean age: 11 years; 51% boys. We measured exposure to maltreatment and perceived stigmatization as an orphan. Mental health was assessed using the Strengths and Difficulties Questionnaire, the Children's Depression Inventory, the UCLA PTSD Index for Children, and the Reactive–Proactive Questionnaire. Results: Orphans reported significantly more experiences of neglect, but not of abuse. A group comparison revealed more depressive symptoms, posttraumatic stress symptoms, and aggressive behavior among orphans. Neglect, abuse, and stigmatization correlated with orphans’ internalizing and externalizing problems, yet only neglect and stigmatization were related to orphans’ depression severity. Perceived stigmatization moderated the relationship between neglect and depression. Conclusions: Our findings suggest that orphans in Tanzania are at increased risk of experiencing neglect. Maltreatment and perceived stigmatization may play a role in orphans’ psychological distress. Culturally appropriate and evidence-based interventions may help to prevent maltreatment and stigmatization of orphans.

    Full Text Available Abstract Background Streptomyces coelicolor, a model organism of antibiotic producing bacteria, has one of the largest genomes of the bacterial kingdom, including 7825 predicted protein coding genes. A large number of these genes, nearly 34%, are functionally orphan (hypothetical proteins with unknown function. However, in gene expression time course data, many of these functionally orphan genes show interesting expression patterns. Results In this paper, we analyzed all functionally orphan genes of Streptomyces coelicolor and identified a list of "high priority" orphans by combining gene expression analysis and additional phylogenetic information (i.e. the level of evolutionary conservation of each protein. Conclusions The prioritized orphan genes are promising candidates to be examined experimentally in the lab for further characterization of their function.

  4. Orphan Sources. Extending Radiological Protection outside the Regulatory Framework

    International Nuclear Information System (INIS)

    Radioactive sources that are not under appropriate regulatory control-Orphan sources- can result in a number of undesirable consequences including human health impacts, socio-psychological impacts, political and economic impacts, as well as environmental impacts. Many countries are now in the process of introducing the necessary measures to regain an appropriate level of control over them. For a variety of historical and economic reasons, there could already be sources in any specific country that are not within the usual regulatory system. Some of these may be known about, others may not. Therefore a national strategy is needed to ascertain the likelihood and magnitude of the issue of radioactive source control problem within a country and the priorities necessary to address the problems identified. A well-developed plan for improving control over all relevant radioactive sources tailored to the national situation will ensure optimum use of resources such as time, money and personnel. It will allow these limited resources to be allocated appropriately to ensure that control is first regained over those sources presenting the highest risks. This lecture shows a way to develop an appropriate national strategy for regaining control over orphan sources. The methodology described in this lecture is basically based in the IAEA Recommendations. (author)

    2015-01-01

    Gamma Ray Bursts are detectable in the gamma-ray band if their jets are oriented towards the observer. However, for each GRB with a typical theta_jet, there should be ~2/theta_jet^2 bursts whose emission cone is oriented elsewhere in space. These off-axis bursts can be eventually detected when, due to the deceleration of their relativistic jets, the beaming angle becomes comparable to the viewing angle. Orphan Afterglows (OA) should outnumber the current population of bursts detected in the gamma-ray band even if they have not been conclusively observed so far at any frequency. We compute the expected flux of the population of orphan afterglows in the mm, optical and X-ray bands through a population synthesis code of GRBs and the standard afterglow emission model. We estimate the detection rate of OA by on-going and forthcoming surveys. The average duration of OA as transients above a given limiting flux is derived and described with analytical expressions: in general OA should appear as daily transients in o...

    The formation of an Ha filament in active region (AR) 10953 is described. Observations from the Solar Optical Telescope (SOT) aboard the Hinode satellite starting on 27th April 2007 until 1st May 2007 were analysed. 20 scans of the 6302A Fe I line pair recorded by SOT/SP were inverted using the SPINOR code. The inversions were analysed together with SOT/BFI G-band and Ca II H and SOT/NFI Ha observations. Following the disappearance of an initial Ha filament aligned along the polarity inversion line (PIL) of the AR, a new Ha filament formed in its place some 20 hours later, which remained stable for at least 1.5 days. The creation of the new Ha filament was driven by the ascent of horizontal magnetic fields from the photosphere into the chromosphere at three separate locations along the PIL. The magnetic fields at two of these locations were situated directly underneath the initial Ha filament and formed orphan penumbrae already aligned along the Ha filament channel. The 700 G orphan penumbrae were stable and ...

    Aaron S Kesselheim

    Full Text Available INTRODUCTION: The Orphan Drug Act encourages drug development for rare conditions. However, some orphan drugs become top sellers for unclear reasons. We sought to evaluate the extent and cost of approved and unapproved uses of orphan drugs with the highest unit sales. METHODS: We assessed prescription patterns for four top-selling orphan drugs: lidocaine patch (Lidoderm approved for post-herpetic neuralgia, modafinil (Provigil approved for narcolepsy, cinacalcet (Sensipar approved for hypercalcemia of parathyroid carcinoma, and imatinib (Gleevec approved for chronic myelogenous leukemia and gastrointestinal stromal tumor. We pooled patient-specific diagnosis and prescription data from two large US state pharmaceutical benefit programs for the elderly. We analyzed the number of new and total patients using each drug and patterns of reimbursement for approved and unapproved uses. For lidocaine patch, we subcategorized approved prescriptions into two subtypes of unapproved uses: neuropathic pain, for which some evidence of efficacy exists, and non-neuropathic pain. RESULTS: We found that prescriptions for lidocaine patch, modafinil, and cinacalcet associated with non-orphan diagnoses rose at substantially higher rates (average monthly increases in number of patients of 14.6, 1.45, and 1.58 than prescriptions associated with their orphan diagnoses (3.12, 0.24, and 0.03, respectively (p75%. Increases in lidocaine patch use for non-neuropathic pain far exceeded neuropathic pain (10.2 vs. 3.6 patients, p<0.001. DISCUSSION: In our sample, three of four top-selling orphan drugs were used more commonly for non-orphan indications. These orphan drugs treated common clinical symptoms (pain and fatigue or laboratory abnormalities. We should continue to monitor orphan drug use after approval to identify products that come to be widely used for non-FDA approved indications, particularly those without adequate evidence of efficacy.

  9. MOTIVATION OF PERSONALITY OF FOSTER CHILD PARENT

    Full Text Available In modern society the question of social protection of orphans and children who are left without parental care is actual. Such children should be transferred to a foster family. Every year increases the number of people willing to take orphans. In the matter of adoption the study of the motivational structure of personality of adoptive parents is a distinguishing novelty and sufficient complexity in the theoretical and practical relations. Due to the increasing secondary orphanhood it becomes necessary to study this psychological component of the individual candidate who wants to take for education the orphan for prevent repeated failure of child. Psychological studies confirm that secondary orphanhood is traumatic for the child and leads to moral and psychological degradation. The article presents an actual problem of modern society – features of motivation of successful parent who has a foster child. It is revealed that in modern psychology there are no single diagnostic tools to determine the motivation of a parent. Thus, there are needs to describe the leading motives of adoptive parents: altruistic, pragmatic, normative, critical. The structure of the author's questionnaire for diagnosing these motifs has been marked. At the same time the disclosure of the individual orientation – manner and working – has been made with the help of diagnostics of the motivational structure of personality (V. D. Milman. Has been presented the results of the research of motivation of parents-women who live with adopted children longer than 1.5 years (children not over 14 years. As a result, it has been founded that successful foster parents have a manner orientation of the personality as a dominating and altruistic (and less normative motivation of the person is identified as a leading.

    Gamma-ray bursts (GRBs) are detectable in the γ-ray band if their jets are oriented toward the observer. However, for each GRB with a typical θjet, there should be ~2/θ2jet bursts whose emission cone is oriented elsewhere in space. These off-axis bursts can eventually be detected when, due to the deceleration of their relativistic jets, the beaming angle becomes comparable to the viewing angle. Orphan afterglows (OAs) should outnumber the current population of bursts detected in the γ-ray band even if they have not been conclusively observed so far at any frequency. We compute the expected flux of the population of orphan afterglows in the mm, optical, and X-ray bands through a population synthesis code of GRBs and the standard afterglow emission model. We estimate the detection rate of OAs with ongoing and forthcoming surveys. The average duration of OAs as transients above a given limiting flux is derived and described with analytical expressions: in general OAs should appear as daily transients in optical surveys and as monthly/yearly transients in the mm/radio band. We find that ~2 OA yr-1 could already be detected by Gaia and up to 20 OA yr-1 could be observed by the ZTF survey. A larger number of 50 OA yr-1 should be detected by LSST in the optical band. For the X-ray band, ~26 OA yr-1 could be detected by the eROSITA. For the large population of OA detectable by LSST, the X-ray and optical follow up of the light curve (for the brightest cases) and/or the extensive follow up of their emission in the mm and radio band could be the key to disentangling their GRB nature from other extragalactic transients of comparable flux density.

  16. They are not always a burden: older people and child fostering in Uganda during the HIV epidemic.

    This qualitative study examines the role of older people (60 years and above) in fostering decisions for orphans and non-orphans within extended families in a rural Ugandan community heavily affected by HIV. Fieldwork conducted in 2006 provided information on the influence of HIV on fostering decisions through 48 individual in-depth interviews and two group interviews with foster-children and family members to develop detailed case studies related to 13 fostered adolescents. The adolescents included five non-orphans and eight orphans (five were double orphans because they had lost both parents). Older people play a very important role in fostering decisions as potential foster-parents, advisers, mediators and gatekeepers. They have a high level of authority over the foster-children, who are regarded as important resources within the extended family. With fewer potential caregivers available because of HIV-related deaths, the responsibility for fostering orphans has often fallen to surviving older people. Fostering is used by older people and the child's extended family as a strategy to ensure the welfare of the foster-child. When the foster-parent is an older person, it is also used to ensure physical and emotional support for the older person themselves. Support from the extended family towards foster households is widely reported to have been reduced by HIV by diminishing resources that would otherwise have been made available to support foster care. New initiatives and investment are required to complement community and family resources within well-managed social protection and welfare programmes. To be effective, such programmes will require adequate investment in administrative capacity and monitoring. They must aim to strengthen families and, recognizing that resources are limited, should prioritize the community's poorest households, rather than specifically targeting households with orphans or other foster-children.

    Full Text Available Objectives: The aim of this study was to assess the prevalence of oral mucosal lesions (OMLs and dental caries and to evaluate oral health practices among institutionalized orphan-children in Sana′a city, Yemen. Subjects and Methods: A sample of 202 institutionalized male-orphan-children in the main orphanage in Sana′a city, were matched to 202 non-orphan schoolchildren. Clinical examination included assessment of OMLs based on standard international diagnostic criteria and evaluation of dental status using the Decayed/decayed, Missed/missed and Filled/filled (DMFT/dmft index according to World Health Organization recommendations. Demographic data and oral hygiene practices were obtained by interviewing each subject using special questionnaire form. Results: Majority of children were in the 12-15 year age group. Nine types of lesions were reported among orphans; the most common lesions were fissured tongue (24.3%, herpes labialis (7.9% and traumatic ulcers (2.5%. The occurrence of herpes labialis was found to be significantly higher in orphans than in controls (P < 0.01. The prevalence of dental caries was insignificantly lower among the orphans (84.7% compared with the non-orphans (89.61%; P = 0.136. The mean dmft score was significantly lower in orphans than in controls (2.28 vs. 3.82; P = 0.001. Conclusions: The institutionalized children in this orphanage had a high prevalence of OMLs but low prevalence of dental caries, though they revealed poor oral hygiene practices. Effective oral health promotion strategies need to be implemented to improve the oral health and oral health practices of children living in orphanages.

    Strategy, Management and Health Policy Large pharmaceutical companies have traditionally focused on the development of blockbuster drugs that target disease states with large patient populations. However, with large-scale patent expirations and competition from generics and biosimilars, anemic pipelines, escalating clinical trial costs, and global health-care reform, the blockbuster model has become less viable. Orphan drug initiatives and the incentives accompanied by these have fostered renewed research efforts in the area of rare diseases and have led to the approval of more than 400 orphan products. Despite targeting much smaller patient populations, the revenue-generating potential of orphan drugs has been shown to be huge, with a greater return on investment than non-orphan drugs. The success of these "niche buster" therapeutics has led to a renewed interest from "Big Pharma" in the rare disease landscape. This article reviews the key drivers for orphan drug research and development, their profitability, and issues surrounding the emergence of large pharmaceutical firms into the orphan drug space.

  7. The detection of orphan radioactive sources and the regulatory attitude

    International Nuclear Information System (INIS)

    In the last decade, the appearance of orphan control radioactive sources has been one constant restlessness in the environment of the regulatory control. Of the well-known cases in the world the more common have been the appearance of type sources or industrial use, which by control lack, by negligence or abandonment were without the due protection and receipt. It is presented in this work the detection of a radioactive source of Cs-137 pickup among the scrap that entered to an important steelworks of the country, by a detector of portal type. Starting from there, Ia Nuclear Regulatory Authority (ARN) it carried out a deep investigation to determine the origin of the radioactive source, which drove to detect and to put low control to other three radioactive sources of the same type used in level measurement, originally housed in a tank of daily consumption of gas-oil, inside a craft that it was broken up for it sale like scrap. During the execution of these tasks they took the regulatory collection, chord to what indicates the normative of the Argentine Republic, harmonized by the international requirements as for the control of radioactive material.

    2015-01-01

    It is generally accepted that the development of novel therapies to treat pregnancy-related disorders, such as preeclampsia, is hampered by the paucity of research funding. Hence, it is with great interest to become aware of at least three novel therapeutic approaches for the treatment of this disorder: exploiting either the anticoagulant activity of antithrombin, the free radical scavenging activity of alpha-1-microglobulin, or the regenerative capacity of placenta-derived mesenchymal stem cells. As these projects are being carried out by small biotech enterprises, the question arises of how they are able to fund such undertakings. A novel strategy adopted by two of these companies is that they successfully petitioned US and EU agencies in order that preeclampsia is accepted in the register of rare or orphan diseases. This provides a number of benefits including market exclusivity, assistance with clinical trials, and dedicated funding schemes. Other strategies to supplement meager research funds, especially to test novel approaches, could be crowdfunding, a venture that relies on intimate interaction with advocacy groups. In other words, preeclampsia meets Facebook. Perhaps similar strategies can be adopted to examine novel therapies targeting either the imbalance in pro- or anti-angiogenic growth factors, complement activation, reduced levels of placenta protein 13, or excessive neutrophil activation evident in preeclampsia.

    Orphan Afterglows (OA) are slow transients produced by Gamma Ray Bursts seen off-axis that become visible on timescales of days/years at optical/NIR and radio frequencies, when the prompt emission at high energies (X and gamma rays) has already ceased. Given the typically estimated jet opening angle of GRBs theta_jet ~ 3 deg, for each burst pointing to the Earth there should be a factor ~ 700 more GRBs pointing in other directions. Despite this, no secure OAs have been detected so far. Through a population synthesis code we study the emission properties of the population of OA at radio frequencies. OAs reach their emission peak on year-timescales and they last for a comparable amount of time. The typical peak fluxes (which depend on the observing frequency) are of few micro Jy in the radio band with only a few OA reaching the mJy level. These values are consistent with the upper limits on the radio flux of SN Ib/c observed at late times. We find that the OA radio number count distribution has a typical slope ...

    The Orphan Basin is a large, deep water basin to the east of Newfoundland and northwest of Flemish Cap, Canada. It contains a considerably wide series of rift basins that provides an excellent opportunity to study continental crustal deformations under varying degrees of extension. We present a 500-km-long P-wave velocity model across the complete rift system of the Orphan Basin, from Flemish Cap to the Bonavista Platform, using high-resolution refraction and wide-angle reflection data from 89 ocean-bottom seismometers (OBS). This layered model builds on a first-arrival traveltime tomography model (Watremez et al., this session) and is formed using additional constraints from a coincident multichannel seismic reflection profile, gravity data and borehole data from three wells. The layered model helps detail deep sediment and crustal variations across this wide region of extended continental crust. The sedimentary section contains post-rift Tertiary (vp~1.7-3.5 km/s) and syn-rift Cretaceous and Jurassic (vp~4-5.4 km/s) layers within both the eastern and the western sub-basins, separated by three basement highs, suggesting that the two sub-basins may have opened during a single, extended rifting event. The crust is composed of three layers with vp of 5.4-6.1, 6.1-6.5 and 6.3-7.1 km/s of highly variable combined thicknesses, from 32 km beneath Flemish Cap and the Bonavista Platform to Orphan Basin, Porcupine Bank and the East Orphan Basin, and the Central Orphan High and Porcupine Bank. Unlike the Rockall and Porcupine Basins, no evidence for partial serpentinization of the upper mantle is observed beneath the E. Orphan trough. However, hyperextension (crustal thickness Orphan trough, which might have allowed the basement to have been covered by syn-rift sediment that inhibited the flow of water down the faults.

  14. Hunting the parent of the Orphan stream. II. The first high-resolution spectroscopic study

    International Nuclear Information System (INIS)

    We present the first high-resolution spectroscopic study on the Orphan stream for five stream candidates, observed with the Magellan Inamori Kyocera Echelle spectrograph on the Magellan Clay telescope. The targets were selected from the low-resolution catalog of Casey et al.: three high-probability members, one medium, and one low-probability stream candidate were observed. Our analysis indicates that the low- and medium-probability targets are metal-rich field stars. The remaining three high-probability targets range over ∼1 dex in metallicity, and are chemically distinct compared to the other two targets and all standard stars: low [α/Fe] abundance ratios are observed, and lower limits are ascertained for [Ba/Y], which sit well above the Milky Way trend. These chemical signatures demonstrate that the undiscovered parent system is unequivocally a dwarf spheroidal galaxy, consistent with dynamical constraints inferred from the stream width and arc. As such, we firmly exclude the proposed association between NGC 2419 and the Orphan stream. A wide range in metallicities adds to the similarities between the Orphan stream and Segue 1, although the low [α/Fe] abundance ratios in the Orphan stream are in tension with the high [α/Fe] values observed in Segue 1. Open questions remain before Segue 1 could possibly be claimed as the 'parent' of the Orphan stream. The parent system could well remain undiscovered in the southern sky.

    Facing substantial obstacles to developing new therapies for rare diseases, some sponsors are looking to 'repurpose' drugs already approved for other conditions and use those therapies to treat rare diseases. In an effort to facilitate such repurposing and speed the delivery of new therapies to people who need them, we have established a new resource, the Rare Disease Repurposing Database (RDRD). The advantages of repurposed compounds include their demonstrated efficacy (in some clinical contexts), their observed toxicity profiles and their clearly described manufacturing controls. To create the RDRD, we matched the US Food and Drug Administration (FDA) orphan designation database to FDA drug and biological product approval lists. The RDRD lists 236 products that have received orphan status designation--that is, were found to be 'promising' for the treatment of a rare disease--and though not yet approved for marketing for that rare disease, they are already approved for marketing to treat some other disease or condition. The RDRD contains three tables: Orphan-designated products with at least one marketing approval for a common disease indication (N = 109); orphan-designated products with at least one marketing approval for a rare disease indication (N = 76); and orphan-designated products with marketing approvals for both common and rare disease indications (N = 51). While the data included in the database is a re-configuration/cross-indexing of information already released by the FDA, it offers sponsors a new tool for finding special opportunities to develop niche therapies for rare disease patients.

    The power of genome sequencing depends on the ability to understand what those genes and their proteins products actually do. The automated methods used to assign functions to putative proteins in newly sequenced organisms are limited by the size of our library of proteins with both known function and sequence. Unfortunately this library grows slowly, lagging well behind the rapid increase in novel protein sequences produced by modern genome sequencing methods. One potential source for rapidly expanding this functional library is the "back catalog" of enzymology--"orphan enzymes," those enzymes that have been characterized and yet lack any associated sequence. There are hundreds of orphan enzymes in the Enzyme Commission (EC) database alone. In this study, we demonstrate how this orphan enzyme "back catalog" is a fertile source for rapidly advancing the state of protein annotation. Starting from three orphan enzyme samples, we applied mass-spectrometry based analysis and computational methods (including sequence similarity networks, sequence and structural alignments, and operon context analysis) to rapidly identify the specific sequence for each orphan while avoiding the most time- and labor-intensive aspects of typical sequence identifications. We then used these three new sequences to more accurately predict the catalytic function of 385 previously uncharacterized or misannotated proteins. We expect that this kind of rapid sequence identification could be efficiently applied on a larger scale to make enzymology's "back catalog" another powerful tool to drive accurate genome annotation.

    Children comprise the largest proportion of the population in sub-Saharan Africa. Of these, millions are orphaned. Orphanhood increases the likelihood of growing up in poverty, dropping out of school, and becoming infected with HIV. Therefore, programs aimed at securing a healthy developmental trajectory for these orphaned children are desperately needed. We conducted a two-arm cluster-randomized controlled trial to evaluate the effectiveness of a family-level economic strengthening intervention with regard to school attendance, school grades, and self-esteem in AIDS-orphaned adolescents aged 12-16 years from 10 public rural primary schools in southern Uganda. Children were randomly assigned to receive usual care (counseling, school uniforms, school lunch, notebooks, and textbooks), "bolstered" with mentorship from a near-peer (control condition, n = 167), or to receive bolstered usual care plus a family-level economic strengthening intervention in the form of a matched Child Savings Account (Suubi-Maka treatment arm, n = 179). The two groups did not differ at baseline, but 24 months later, children in the Suubi-Maka treatment arm reported significantly better educational outcomes, lower levels of hopelessness, and higher levels of self-concept compared to participants in the control condition. Our study contributes to the ongoing debate on how to address the developmental impacts of the increasing numbers of orphaned and vulnerable children and adolescents in sub-Saharan Africa, especially those affected by HIV/AIDS. Our findings indicate that innovative family-level economic strengthening programs, over and above bolstered usual care that includes psychosocial interventions for young people, may have positive developmental impacts related to education, health, and psychosocial functioning.

    Orphan Afterglows (OA) are slow transients produced by Gamma Ray Bursts seen off-axis that become visible on timescales of days/years at optical/NIR and radio frequencies, when the prompt emission at high energies (X and γ rays) has already ceased. Given the typically estimated jet opening angle of GRBs θjet ~ 3°, for each burst pointing to the Earth there should be a factor ~ 700 more GRBs pointing in other directions. Despite this, no secure OAs have been detected so far. Through a population synthesis code we study the emission properties of the population of OA at radio frequencies. OAs reach their emission peak on year-timescales and they last for a comparable amount of time. The typical peak fluxes (which depend on the observing frequency) are of few μJy in the radio band with only a few OA reaching the mJy level. These values are consistent with the upper limits on the radio flux of SN Ib/c observed at late times. We find that the OA radio number count distribution has a typical slope - 1.7 at high fluxes and a flatter ( - 0.4) slope at low fluxes with a break at a frequency-dependent flux. Our predictions of the OA rates are consistent with the (upper) limits of recent radio surveys and archive searches for radio transients. Future radio surveys like VAST/ASKAP at 1.4 GHz should detect ~ 3 × 10- 3 OA deg- 2 yr- 1, MeerKAT and EVLA at 8.4 GHz should see ~ 3 × 10- 1 OA deg- 2 yr- 1. The SKA, reaching the μJy flux limit, could see up to ~ 0.2 - 1.5 OA deg- 2 yr- 1. These rates also depend on the duration of the OA above a certain flux limit and we discuss this effect with respect to the survey cadence.

  3. Hadronic-Origin orphan TeV flare from the 1ES 1959+650

    Sahu, Sarira; Sanabria, Juan Carlos

    2013-01-01

    The 1ES 1959+650 is a high-peaked BL Lacertae object. On 4th of June, 2002, it exhibited a strong TeV flare without any low energy counterpart, providing for the first time an example of an orphan flare from a blazar. Observation of this orphan flare is in striking disagreement with the predictions of the leptonic models thus challenging the conventional synchrotron self-Compton (SSC) interpretation of the TeV emission. Here we propose that, the low energy tail of the SSC photons in the blazar jet serve as the target for the Fermi-accelerated high energy protons of energy . 100 TeV, within the jet to produce the TeV photons through the decay of neutral pions from the delta resonance. Our model explains very nicely the observed TeV flux from this orphan flare and we also estimate the high energy neutrino flux from this flaring event.

    Evidence suggests that a regular and reliable transfer of cash to households with orphaned and vulnerable children has a strong and positive effect on child outcomes. However, conditional cash transfers are considered by some as particularly intrusive and the question on whether or not to apply conditions to cash transfers is an issue of controversy. Contributing to policy debates on the appropriateness of conditions, this article sets out to investigate the overall buy-in of conditions by different stakeholders and to identify pathways that contribute to an acceptability of conditions. The article draws on data from a cluster-randomized trial of a community-led cash transfer programme in Manicaland, eastern Zimbabwe. An endpoint survey distributed to 5167 households assessed community members' acceptance of conditions and 35 in-depth interviews and 3 focus groups with a total of 58 adults and 4 youth examined local perceptions of conditions. The study found a significant and widespread acceptance of conditions primarily because they were seen as fair and a proxy for good parenting or guardianship. In a socio-economic context where child grants are not considered a citizen entitlement, community members and cash transfer recipients valued the conditions associated with these grants. The community members interpreted the fulfilment of the conditions as a proxy for achievement and merit, enabling them to participate rather than sit back as passive recipients of aid. Although conditions have a paternalistic undertone and engender the sceptics' view of conditions being pernicious and even abominable, it is important to recognize that community members, when given the opportunity to participate in programme design and implementation, can take advantage of conditions and appropriate them in a way that helps them manage change and overcome the social divisiveness or conflict that otherwise may arise when some people are identified to benefit and others not.

    Parental death affects the life of children in many ways, one of which is self-esteem problems. Providing psychosocial support and equipping orphans play a vital role in their lifes. A cross-sectional study was conducted on 7-18-year-old orphans at 17 local districts of Gamo Gofa Zone, Southern Regional State of Ethiopia. From a total of 48,270 orphans in these areas, 4,368 were selected using stratified simple random sampling technique. Data were collected with a designed questionnaire based on the Rosenberg's rating scale to measure their self-esteem levels. Self-esteem with a score less than or equal to an average score was considered to be low self-esteem in the analysis. Binary logistic regression model was used to analyze the data using the SPSS software. The results of the study revealed that the probability of orphans suffering from low self-esteem was 0.59. Several risk factors were found to be significant at the level of 5%. Psychosocial support (good guidance, counseling and treatment, physical protection and amount of love shared, financial and material support, and fellowship with other children), parents living together before death, strong relationship between parents before death, high average monthly income, voluntary support, and consideration from the society are some of the factors that decrease the risk of being low in self-esteem. There are many orphans with low self-esteem in the study areas. The factors negatively affecting the self-esteem of orphans include the lack of psychosocial support, poor social life of parents, and death of parents due to AIDS. Society and parents should be aware of the consequences of these factors which can influence their children's future self-esteem. PMID:26508894

    We investigate the dynamics and magnetic properties of orphan penumbrae observed in the solar photosphere to understand the formation process of such structures. We observed two orphan penumbrae in active region NOAA 11089 during a coordinated observing campaign carried out in 2010 July, involving the Hinode/Solar Optical Telescope (SOT) and Dutch Open Telescope (DOT), benefiting also from continuous observations acquired by the SDO satellite. We follow their evolution during about three days. The two structures form in different ways: one seems to break off the penumbra of a nearby sunspot, the other is formed through the emergence of new flux. Then they fragment while evolving. The SDO Helioseismic and Magnetic Imager measurements indicate the presence of strong line-of-sight motions in the regions occupied by these orphan penumbrae, lasting for several hours and decreasing with time. This is confirmed by SOT spectro-polarimetric measurements of the Fe I 630.2 nm pair. The latter also show that Stokes parameters exhibit significant asymmetries in the orphan penumbral regions, typical of an uncombed filamentary structure. The orphan penumbrae lie above polarity inversion lines, where peculiar plasma motions take place with velocities larger than ±3 km s-1. The vector magnetic field in these regions is highly inclined, with the average magnetic field strength decreasing with time. The DOT observations in the Hα line and SDO Atmospheric Imaging Assembly measurements in the He II 30.4 nm line indicate that there is no counterpart for the orphan penumbrae at midchromospheric heights or above. Our findings suggest that in at least one of the features investigated the emerging flux may be trapped in the low atmospheric layers by the overlying pre-existing fields, forming these filamentary structures.

    The Orphan Basin is located in the deep offshore of the Newfoundland margin, and it is bounded by the continental shelf to the west, the Grand Banks to the south, and the continental blocks of Orphan Knoll and Flemish Cap to the east. The Orphan Basin formed in Mesozoic time during the opening of the North Atlantic Ocean between eastern Canada and western Iberia-Europe. This work, based on well data and regional seismic reflection profiles across the basin, indicates that the continental crust was affected by several extensional episodes between the Jurassic and the Early Cretaceous, separated by events of uplift and erosion. The preserved tectono-stratigraphic sequences in the basin reveal that deformation initiated in the eastern part of the Orphan Basin in the Jurassic and spread towards the west in the Early Cretaceous, resulting in numerous rift structures filled with a Jurassic-Lower Cretaceous syn-rift succession and overlain by thick Upper Cretaceous to Cenozoic post-rift sediments. The seismic data show an extremely thinned crust (4-16 km thick) underneath the eastern and western parts of the Orphan Basin, forming two sub-basins separated by a wide structural high with a relatively thick crust (17 km thick). Quantifying the crustal architecture in the basin highlights the large discrepancy between brittle extension localized in the upper crust and the overall crustal thinning. This suggests that continental deformation in the Orphan Basin involved, in addition to the documented Jurassic and Early Cretaceous rifting, an earlier brittle rift phase which is unidentifiable in seismic data and a depth-dependent thinning of the crust driven by localized lower crust ductile flow.

    The Early Cretaceous separation of Newfoundland from Iberia-Ireland is a classic example of a magma-poor continental margin with hyperextension and with widespread minor magmatism resulting in seamounts. This study defines the distribution of seamounts east of Orphan Knoll, and documents and interprets the geochemical character of the one recovered lava sample. Video imagery of lava outcrops, and the sample, were obtained by ROV from Orphan seamount, one of a linear series of small seamounts overlying transitional thinned continental crust on the seaward side of Orphan Knoll. New multibeam bathymetry and legacy seismic data show several seamounts that extend irregularly along the fault-bound NE margin of Orphan Knoll. Whole rock geochemistry shows the sample to be highly alkaline basanite or possibly tephrite. Diopside-hedenbergite, kaersutite and K-feldspar phenocrysts were analyzed by electron microprobe and scanning electron microscope, and alteration minerals including kaolinite were identified by X-ray diffraction. The highly alkaline character of the basanite is similar only to Early Cretaceous volcanic and sub-volcanic rocks erupted through thick continental crust of the Mesoproterozoic Grenville Orogeny. The location of the linear set of seamounts is related to margin-parallel faults on the seaward side of Orphan Knoll that provided a pathway for magma, although ENE-trending lineaments in individual seamounts or seamount groups suggest the influence of oceanic fracture zones. A lower gradient crest to Orphan seamount above 2,200 m suggests subaerial erosion, consistent with the presence of kaolinite as an alteration product and the absence of lava pillows at and above this depth.

    In Sub-Saharan Africa, 15.1 million children have been orphaned because of human immunodeficiency virus (HIV). They face significant vulnerabilities, including stigma and discrimination, trauma and stress, illness, food insecurity, poverty, and difficulty accessing education. Millions of additional children who have living parents are vulnerable because their parents or other relatives are infected. This article reviews the current situation of orphans and vulnerable children, explores the underlying determinants of vulnerability and resilience, describes the response by the global community, and highlights the challenges as the HIV pandemic progresses through its fourth decade.

    Full Text Available The aftermath of the HIV and AIDS pandemic has resulted in great suffering in terms of loss of income, poor quality of life, morbidity and mortality, with children being destitute and orphaned at an alarming rapid rate. Families and communities are currently unable to cope with the effects of HIV and AIDS with special emphasis on the care and support of the affected orphans and vulnerable children, who as a result have been compelled to look after themselves giving rise to a new type of family, the child-headed household. The emergence of this type of family requires government’s response in terms of care and support. The purpose of this study was to provide a broad picture of the location, prevalence, composition, functions, needs and challenges of child-headed households in South Africa, and explore available and required services, resources and safety nets for children in child-headed households. An exploratory and descriptive design was used for the purpose. The sample consisted of children heading households and those living in the households that are headed by children; government departments responsible for child welfare, such as, the Departments of Social Development, Health, Education and Agriculture; non-profit organisations and communities where these households are predominant. From the data collected, it was found that the rights of the affected children were compromised. Those heading the households were often not at school and were responsible for domestic chores. The households needed food, clothes, money, shelter, and education. Government in attempting to address these needs required clear policies which will provide a distinction between orphaned and vulnerable children and child-headed households.The study recommended a collaborative approach as it was shown that there was no single model of best practice to appropriately and effectively address the needs of child-headed households.

    Mark Gary Embrett

    2014-02-01

    Full Text Available The Ministry of Health’s announcement of a National Orphan Drug Framework on 3 October 2012 was the first federal public acknowledgement of orphan drugs since the 1997 Drugs Directorate (DD policy statement. The reform primarily announced an Orphan Drug Policy for Canada. This paper explains why the government decided to make this announcement now. Media and Parliamentary documents were analyzed for their use of symbols, numbers, and language in causal stories told by political actors. The initial story was that Canada’s population was too small and the cost too high for an orphan drug policy. Over the next fifteen years, a powerful interest group, the Canadian Organization for Rare Disorders (CORD, mobilized the rare disease community into a cooperative effort that generated collective action. They redefined the DD story from one of natural causes, to inadvertence, and finally to intentional causation. Their story invoked a federal response because it blamed the government directly for not acting on behalf of the 3 million Canadians with rare diseases, when patients in other countries were receiving better care.

    2010-01-01

    The HIV/AIDS epidemic has continued to pose significant challenges to countries in Sub-Saharan Africa. Millions of African children and youth have lost parents to HIV/AIDS leaving a generation of orphans to be cared for within extended family systems and communities. The experiences of youth who have lost parents to the HIV/AIDS epidemic provide an important ingress into this complex, evolving, multi-dimensional phenomenon. A fundamental qualitative descriptive study was conducted to develop a culturally relevant and comprehensive description of the experiences of orphanhood from the perspectives of Ugandan youth. A purposeful sample of 13 youth who had lost one or both parents to HIV/AIDS and who were affiliated with a non-governmental organization providing support to orphans were interviewed. Youth orphaned by HIV/AIDS described the experience of orphanhood beginning with parental illness, not death. Several losses were associated with the death of a parent including lost social capitol, educational opportunities and monetary assets. Unique findings revealed that youth experienced culturally specific stigma and conflict which was distinctly related to their HIV/AIDS orphan status. Exploitation within extended cultural family systems was also reported. Results from this study suggest that there is a pressing need to identify and provide culturally appropriate services for these Ugandan youth prior to and after the loss of a parent(s).

    Full Text Available Abstract Background An estimated 2 million children are parentally bereaved by AIDS in South Africa. Little is known about mental health outcomes for this group. Methods This study aimed to investigate mental health outcomes for urban children living in deprived settlements in Cape Town. 30 orphaned children and 30 matched controls were compared using standardised questionnaires (SDQ on emotional and behavioural problems, peer and attention difficulties, and prosocial behaviour. The orphan group completed a modified version of a standardised questionnaire (IES-8, measuring Post-Traumatic Stress symptoms. Group differences were tested using t-tests and Pearson's chi-square. Results Both groups scored highly for peer problems, emotional problems and total scores. However, orphans were more likely to view themselves as having no good friends (p = .002, to have marked concentration difficulties (p = .03, and to report frequent somatic symptoms (p = .05, but were less likely to display anger through loss of temper (p = .03. Orphans were more likely to have constant nightmares (p = .01, and 73% scored above the cut-off for Post-Traumatic Stress Disorder. Conclusion Findings suggest important areas for larger-scale research for parentally-bereaved children.

  10. Exploring emerging technologies using metaphors--a study of orphan drugs and pharmacogenomics.

    2008-05-01

    Due to uncertainties of several aspects of emerging health technologies, there is a need to anticipate these developments early. A first step would be to gather information and develop future visions about the technology. This paper introduces metaphor analysis as a novel way to do this. Specifically, we study the future of pharmacogenomics by comparing this technology with orphan drugs, which are more established and often act as a model with comparable (economic, research organisation, etc.) characteristics. The analysis consists of describing the dominant metaphors used and structurally exploring (dis)similarities between pharmacogenomics and orphan drugs developments. This comparison leads to lessons that can be learnt for the emerging pharmacogenomics future. We carried out a comprehensive literature review, extracting metaphors in a structured way from different areas of the drug research and development pipeline. The paper argues that (1) there are many similarities between orphan drugs and pharmacogenomics, especially in terms of registration, and social and economic impacts; (2) pharmacogenomics developments are regarded both as a future 'poison' and a 'chance', whereas orphan drugs are seen as a 'gift', and at the same time as a large 'problem'; and (3) metaphor analysis proves to be a tool for creating prospective images of pharmacogenomics and other emerging technologies.

    We report positions, velocities and metallicities of 50 ab-type RR Lyrae (RRab) stars observed in the vicinity of the Orphan stellar stream. Using about 30 RRab stars classified as being likely members of the Orphan stream, we study the metallicity and the spatial extent of the stream. We find that RRab stars in the Orphan stream have a wide range of metallicities, from -1.5 dex to -2.7 dex. The average metallicity of the stream is -2.1 dex, identical to the value obtained by Newberg et al. (2010) using blue horizontal branch stars. We find that the most distant parts of the stream (40-50 kpc from the Sun) are about 0.3 dex more metal-poor than the closer parts (within ~30 kpc), suggesting a possible metallicity gradient along the stream's length. We have extended the previous studies and have mapped the stream up to 55 kpc from the Sun. Even after a careful search, we did not identify any more distant RRab stars that could plausibly be members of the Orphan stream. If confirmed with other tracers, this resul...

  2. Reconsidering the orphan problem: the emergence of male caregivers in Lesotho.

    Care for AIDS orphans in southern Africa is frequently characterized as a "crisis", where kin-based networks of care are thought to be on the edge of collapse. Yet these care networks, though strained by AIDS, are still the primary mechanisms for orphan care, in large part because of the essential role grandmothers play in responding to the needs of orphans. Ongoing demographic shifts as a result of HIV/AIDS and an increasingly feminized labor market continue to disrupt and alter networks of care for orphans and vulnerable children. This paper examines the emergence of a small but growing number of male caregivers who are responding to the needs of the extended family. While these men are still few in number, the strength of gendered ideologies of female care means that this group of men is socially, if not statistically significant. Men continue to be considered caregivers of last resort, but their care will close a small but growing gap that threatens to undermine kin-based networks of care in Lesotho and across the region. The adaptation of gender roles reinforces the strength and resilience of kinship networks even when working against deeply entrenched ideas about gendered division of domestic labor. PMID:27297796

  6. A generalizable pre-clinical research approach for orphan disease therapy

    Full Text Available Abstract With the advent of next-generation DNA sequencing, the pace of inherited orphan disease gene identification has increased dramatically, a situation that will continue for at least the next several years. At present, the numbers of such identified disease genes significantly outstrips the number of laboratories available to investigate a given disorder, an asymmetry that will only increase over time. The hope for any genetic disorder is, where possible and in addition to accurate diagnostic test formulation, the development of therapeutic approaches. To this end, we propose here the development of a strategic toolbox and preclinical research pathway for inherited orphan disease. Taking much of what has been learned from rare genetic disease research over the past two decades, we propose generalizable methods utilizing transcriptomic, system-wide chemical biology datasets combined with chemical informatics and, where possible, repurposing of FDA approved drugs for pre-clinical orphan disease therapies. It is hoped that this approach may be of utility for the broader orphan disease research community and provide funding organizations and patient advocacy groups with suggestions for the optimal path forward. In addition to enabling academic pre-clinical research, strategies such as this may also aid in seeding startup companies, as well as further engaging the pharmaceutical industry in the treatment of rare genetic disease.

    Full Text Available Abstract The HIV/AIDS epidemic has continued to pose significant challenges to countries in Sub-Saharan Africa. Millions of African children and youth have lost parents to HIV/AIDS leaving a generation of orphans to be cared for within extended family systems and communities. The experiences of youth who have lost parents to the HIV/AIDS epidemic provide an important ingress into this complex, evolving, multi-dimensional phenomenon. A fundamental qualitative descriptive study was conducted to develop a culturally relevant and comprehensive description of the experiences of orphanhood from the perspectives of Ugandan youth. A purposeful sample of 13 youth who had lost one or both parents to HIV/AIDS and who were affiliated with a non-governmental organization providing support to orphans were interviewed. Youth orphaned by HIV/AIDS described the experience of orphanhood beginning with parental illness, not death. Several losses were associated with the death of a parent including lost social capitol, educational opportunities and monetary assets. Unique findings revealed that youth experienced culturally specific stigma and conflict which was distinctly related to their HIV/AIDS orphan status. Exploitation within extended cultural family systems was also reported. Results from this study suggest that there is a pressing need to identify and provide culturally appropriate services for these Ugandan youth prior to and after the loss of a parent(s.

Providing psychosocial support and equipping orphans play a vital role in their lifes. A cross-sectional study was conducted on 7–18-year-old orphans at 17 local districts of Gamo Gofa Zone, Southern Regional State of Ethiopia. From a total of 48,270 orphans in these areas, 4,368 were selected using stratified simple random sampling technique. Data were collected with a designed questionnaire based on the Rosenberg's rating scale to measure their self-esteem levels. Self-esteem with a score less than or equal to an average score was considered to be low self-esteem in the analysis. Binary logistic regression model was used to analyze the data using the SPSS software. The results of the study revealed that the probability of orphans suffering from low self-esteem was 0.59. Several risk factors were found to be significant at the level of 5%. Psychosocial support (good guidance, counseling and treatment, physical protection and amount of love shared, financial and material support, and fellowship with other children, parents living together before death, strong relationship between parents before death, high average monthly income, voluntary support, and consideration from the society are some of the factors that decrease the risk of being low in self-esteem. There are many orphans with low self-esteem in the study areas. The factors negatively affecting the self-esteem of orphans include the lack of psychosocial support, poor social life of parents, and death of parents due to AIDS. Society and parents should be aware of the consequences of these factors which can influence their children's future self

    We report positions, velocities, and metallicities of 50 ab-type RR Lyrae (RRab) stars observed in the vicinity of the Orphan stellar stream. Using about 30 RRab stars classified as being likely members of the Orphan stream, we study the metallicity and the spatial extent of the stream. We find that RRab stars in the Orphan stream have a wide range of metallicities, from –1.5 dex to –2.7 dex. The average metallicity of the stream is –2.1 dex, identical to the value obtained by Newberg et al. using blue horizontal branch stars. We find that the most distant parts of the stream (40-50 kpc from the Sun) are about 0.3 dex more metal-poor than the closer parts (within ∼30 kpc), suggesting a possible metallicity gradient along the stream's length. We have extended the previous studies and have mapped the stream up to 55 kpc from the Sun. Even after a careful search, we did not identify any more distant RRab stars that could plausibly be members of the Orphan stream. If confirmed with other tracers, this result would indicate a detection of the end of the leading arm of the stream. We have compared the distances of Orphan stream RRab stars with the best-fit orbits obtained by Newberg et al. We find that model 6 of Newberg et al. cannot explain the distances of the most remote Orphan stream RRab stars, and conclude that the best fit to distances of Orphan stream RRab stars and to the local circular velocity is provided by potentials where the total mass of the Galaxy within 60 kpc is M{sub 60} ∼ 2.7 × 10{sup 11} M{sub ☉}, or about 60% of the mass found by previous studies. More extensive modeling that would consider non-spherical potentials and the possibility of misalignment between the stream and the orbit is highly encouraged.

    Stigma and marginalization are one of the major challenges orphans face in their daily lives, particularly in developing countries, but little is known about their impacts on mental health. This study examines how orphan-related characteristics, stigma and marginalization are associated with psychosocial well-being. It further analyses the role of social support in mediating between stigma and marginalization and mental health, indicated by emotional well-being and mental distress. The participants in this study were 430 Rwandan orphans who were 10-25 years of age, and of whom 179 were females and 251 were males. Results showed that high levels of stigma and marginalization were associated with a lower level of emotional well-being and higher levels of mental distress. A mediation analysis indicated that low level of social support due to stigma and marginalization contributed significantly to low level of emotional well-being. Once stigma, marginalization and social support were fully accounted for, AIDS orphans exhibited higher levels of mental distress than those who were orphaned by genocide or other causes. Future interventions designed to reduce stigma and marginalization for orphans and actions that facilitate social support can significantly improve emotional well-being and reduce mental distress among orphans.

    Full Text Available The purpose of this study was to evaluate the extent of constitutive activity among orphan class-A G protein coupled receptors within the cAMP signaling pathway. Constitutive signaling was revealed by changes in gene expression under control of the cAMP response element. Gene expression was measured in Chinese hamster ovary cells transiently co-transfected with plasmids containing a luciferase reporter and orphan receptor. Criteria adopted for defining constitutive activation were: 1 200% elevation over baseline reporter gene expression; 2 40% inhibition of baseline expression; and 3 40% inhibition of expression stimulated by 3 μM forskolin. Five patterns of activity were noted: 1 inhibition under both baseline and forskolin stimulated expression (GPR15, GPR17, GPR18, GPR20, GPR25, GPR27, GPR31, GPR32, GPR45, GPR57, GPR68, GPR83, GPR84, GPR132, GPR150, GPR176; 2 no effect on baseline expression, but inhibition of forskolin stimulated expression (GPR4, GPR26, GPR61, GPR62, GPR78, GPR101, GPR119; 3 elevation of baseline signaling coupled with inhibition of forskolin stimulated expression (GPR6, GPR12; 4 elevation of baseline signaling without inhibition of forskolin stimulated expression (GPR3, GPR21, GPR52, GPR65; and 5 no effect on expression (GPR1, GPR19, GPR22, GPR34, GPR35, GPR39, GPR63, GPR82, GPR85, GPR87. Constitutive activity was observed in 75% of the orphan class-A receptors examined (30 of 40. This constitutive signaling cannot be explained by simple overexpression of the receptor. Inhibition of cAMP mediated expression was far more common (65% than stimulation of expression (15%. Orphan receptors that were closely related based on amino acid homology tended to have similar effects on gene expression. These results suggest that identification of inverse agonists may be a fruitful approach for categorizing these orphan receptors and targeting them for pharmacological intervention.

  17. The disposal of orphan wastes using the greater confinement disposal concept

    International Nuclear Information System (INIS)

    In the United States, radioactive wastes are conventionally classified as high-level wastes, transuranic wastes, or low-level wastes. Each of these types of wastes, by law, has a ''home'' for their final disposal; i.e., high-level wastes are destined for disposal at the proposed repository at Yucca Mountain, transuranic waste for the proposed Waste Isolation Pilot Plant, and low-level waste for shallow-land disposal sites. However, there are some radioactive wastes within the United States Department of Energy (DOE) complex that do not meet the criteria established for disposal of either high-level waste, transuranic waste, or low-level waste. The former are called ''special-case'' or ''orphan'' wastes. This paper describes an ongoing project sponsored by the DOE's Nevada Operations Office for the disposal of orphan wastes at the Radioactive Waste Management Site at Area 5 of the Nevada Test Site using the greater confinement disposal (GCD) concept. The objectives of the GCD project are to evaluate the safety of the site for disposal of orphan wastes by assessing compliance with pertinent regulations through performance assessment, and to examine the feasibility of this disposal concept as a cost-effective, safe alternative for management of orphan wastes within the DOE complex. Decisions on the use of GCD or other alternate disposal concepts for orphan wastes be expected to be addressed in a Programmatic Environmental Impact Statement being prepared by DOE. The ultimate decision to use GCD will require a Record of Decision through the National Environmental Policy Act (NEPA) process. 20 refs., 3 figs., 2 tabs

    We present the first high-resolution spectroscopic study on the Orphan stream for five stream candidates, observed with the Magellan Inamori Kyocera Echelle spectrograph on the Magellan Clay telescope. The targets were selected from the low-resolution catalog of Casey et al.: three high-probability members, one medium, and one low-probability stream candidate were observed. Our analysis indicates that the low- and medium-probability targets are metal-rich field stars. The remaining three high-probability targets range over ~1 dex in metallicity, and are chemically distinct compared to the other two targets and all standard stars: low [α/Fe] abundance ratios are observed, and lower limits are ascertained for [Ba/Y], which sit well above the Milky Way trend. These chemical signatures demonstrate that the undiscovered parent system is unequivocally a dwarf spheroidal galaxy, consistent with dynamical constraints inferred from the stream width and arc. As such, we firmly exclude the proposed association between NGC 2419 and the Orphan stream. A wide range in metallicities adds to the similarities between the Orphan stream and Segue 1, although the low [α/Fe] abundance ratios in the Orphan stream are in tension with the high [α/Fe] values observed in Segue 1. Open questions remain before Segue 1 could possibly be claimed as the "parent" of the Orphan stream. The parent system could well remain undiscovered in the southern sky. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile.

  1. Child abuse

    International Nuclear Information System (INIS)

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)

    HIV and AIDS have altered the context in which millions of children in sub-Saharan Africa are raised. Many are under the care of a widowed or ill parent, and others are residing with their extended family. Caregivers of orphans and other vulnerable children (OVC) face a variety of stressors that may adversely affect children. This study explores potential benefits of caregivers' membership in support groups on their own psychosocial wellbeing, and on the treatment and psychosocial well-being of OVC aged 8-14 under their care. A post-test study design comparing members and non-members was applied, drawing upon random samples of current and prospective beneficiaries from a rural community in Kenya. With up to two children per caregiver eligible for study inclusion, the sample comprised 766 caregivers and 1028 children. Three-quarters of children had lost at least one parent. Nearly 90% were cared for by a female, often their natural mother or grandmother. Half of the caregivers were widowed and one-fifth had a chronic illness. Over one-third of caregivers were members of support groups, more commonly female caregivers. Regression analyses assessed the effect of support group membership after controlling for household, caregiver and child characteristics. Members reported less social marginalization, better family functioning and more positive feelings towards the children in their care than nonmembers. Children with caregivers in support groups exhibited fewer behavioral problems, higher rates of prosocial behavior and reported lower incidence of abuse from adults in their household. The psychological state of caregivers, however, was not associated with support group membership. Results underscore that quality care of vulnerable children hinges on interventions that address the psychosocial challenges facing their caregivers.

    Full Text Available Abstract Background The AIDS epidemic has lead to an increase in orphaned children who need residential care. It is known that HIV leads to delayed motor development. However, the impact of place of residence on motor function has not been investigated in the South African context. The aim of the study was therefore to establish if children in institutionalised settings performed better or worse in terms of gross motor function than their counterparts in foster care. A secondary objective was to compare the performance of children with HIV in these two settings with those of children who were HIV negative. Methods Forty-four children both with and without HIV, were recruited from institutions and foster care families in Cape Town. The Peabody Development Motor Scale (PDMS II was used to calculate the total motor quotient (TMQ at baseline and six months later. Comparisons of TMQ were made between residential settings and between children with and without HIV. Results Twenty-one children were infected with HIV and were significantly delayed compared to their healthy counterparts. Antiretroviral therapy was well managed among the group but did not appear to result in restoration of TMQ to normal over the study period. HIV status and place of residence emerged as a predictor of TMQ with children in residential care performing better than their counterparts in foster care. All children showed improvement over the six months of study. Conclusions Foster parents were well supported administratively in the community by social welfare services but their children might have lacked stimulation in comparison to those in institutional settings. This could have been due to a lack of resources and knowledge regarding child development. The assumption that foster homes provide a better alternative to institutions may not be correct in a resource poor community and needs to be examined further.

An abandoned well refers to those wells that are no longer active and have been properly plugged. A total of 19 orphan wells were discovered with the help of landowners and historical maps. These wells are believed to have dated from 1860 to 1906. The locations of the wells were determined digitally using the Global Positioning System. The environmental conditions around the orphan wells were evaluated and classified according to a proposed system used by the State of Michigan. The wells were separated into three categories based on the amount of petroleum contamination of soil and water. Water contamination was further divided into contamination of groundwater and surface water. 7 refs., 34 figs

    Full Text Available Abstract Background Africa is in an orphan-care crisis. In Zimbabwe, where one-fourth of adults are HIV-positive and one-fifth of children are orphans, AIDS and economic decline are straining society's ability to care for orphans within their extended families. Lack of stable care is putting thousands of children at heightened risk of malnourishment, emotional underdevelopment, illiteracy, poverty, sexual exploitation, and HIV infection, endangering the future health of the society they are expected to sustain. Methods To explore barriers and possible incentives to orphan care, a quantitative cross-sectional survey in rural eastern Zimbabwe asked 371 adults caring for children, including 212 caring for double orphans, about their well-being, needs, resources, and perceptions and experiences of orphan care. Results Survey responses indicate that: 1 foster caregivers are disproportionately female, older, poor, and without a spouse; 2 98% of non-foster caregivers are willing to foster orphans, many from outside their kinship network; 3 poverty is the primary barrier to fostering; 4 financial, physical, and emotional stress levels are high among current and potential fosterers; 5 financial need may be greatest in single-orphan AIDS-impoverished households; and 6 struggling families lack external support. Conclusion Incentives for sustainable orphan care should focus on financial assistance, starting with free schooling, and development of community mechanisms to identify and support children in need, to evaluate and strengthen families' capacity to provide orphan care, and to initiate and support placement outside the family when necessary.

  12. 'Older women', customary obligations and orphan foster caregiving: the case of queen mothers in Manya Klo, Ghana.

    Science.gov (United States)

    Drah, Bright B

    2014-06-01

    Female orphan caregivers in countries heavily affected by HIV in sub-Saharan Africa are often presented as a homogenous group of vulnerable 'older women' that struggles to support orphans. There is a dearth of data on the different kinds of women and how their social characteristics impact their survival strategies and caregiving responsibilities. This study examines the link between the social characteristics of queen mothers in Manya Klo in Ghana and their roles as caregivers. The research findings suggest that queen mothers have become the primary caregivers of orphans, even though they do not have the wherewithal to provide for these orphans. The lack of kin support to queen mothers exacerbates their physical and economic vulnerabilities. They engage in less dignifying economic activities and pay less attention to their own needs in order to meet their customary obligations as orphan caregivers. The growing influence of queen mothers as caregivers for orphans, however, is a reflection of some of the changes that are occurring in customary foster care arrangements. Policy makers and interventionists require in depth understanding of queen mothers and their peculiar circumstances in order to strengthen their roles as leaders and caregivers. PMID:24737050

    Full Text Available The termite Coptotermes gestroi (Wasmann, 1896 (Rhinotermitidae: Coptotermitinae is an exotic species in Brazil and information concerning its reproductive developmental biology is scarce. We induced the formation of neotenics in laboratory colonies through orphaning experiments. Orphaning experiments were conducted in three-year old colonies of C. gestroi kept under laboratory conditions. After three months, eight nymphoid neotenics were observed in one colony after queen removal. Histological analysis showed that these neotenics were non-functional. The results suggest that these individuals may have arisen from the first nymphal instar (N1 or from an early N1 instar after one or two larval moults. Neotenics also were recorded on two incipient colonies of C. gestroi that lost the queen naturally.

    2008-09-01

    Huntington's disease (HD) is a rare neurodegenerative disorder that progressively destroys the mental capacity and motor control of patients. This loss of motor control results in abnormal body movements (chorea) - the hallmark of HD. Given that no disease-modifying therapy for HD exists and that available symptomatic treatments are not highly efficacious, the medical need for this 'orphan' disease remains high. The number of compounds that are undergoing discovery and development for the treatment of HD has increased significantly in recent years, spurred by legislative incentives for orphan drug development and by support from non-profit foundations. Thus, hope exists for patients with HD that efficacious medicines will become available. PMID:18763216

    2016-11-01

    We propose that {\\gamma} -rays in blazars can be produced during encounters of relativistic blobs of plasma with radiation field produced by luminous stars within (or close to) the jet. The blob is expected to contain relativistic electrons which comptonize stellar radiation to the GeV-TeV energies. Produced {\\gamma} -rays can initiate the Inverse Compton e+/- pair cascade in the stellar radiation. We propose that such a scenario can be responsible for the appearance of the so-called orphan {\\gamma} -ray flares. We show that the relativistic blob/luminous star collision model can explain the appearance of the extreme orphan {\\gamma} -ray flare observed in the GeV and sub-TeV energy range from the flat spectrum radio quasar PKS 1222+21.

    DNA gyrase is an essential topoisomerase found in all bacteria. It is encoded by gyrB and gyrA genes. These genes are organized differently in different bacteria. Direct comparison of Mycobacterium tuberculosis and Mycobacterium smegmatis genomes reveals presence of an additional gyrB in M. smegmatis flanked by novel genes. Analysis of the amino acid sequence of GyrB from different organisms suggests that the orphan GyrB in M. smegmatis may have an important cellular role.

  8. National campaign for the search and recovery of Orphan radioactive sources

    International Nuclear Information System (INIS)

    This paper aims to describe the main initial approaches of the campaign for the 'Recovery of Orphan Radioactive Sources' undertaken in Spain, in addition to the steps taken, the experience gained and the partial results obtained. The campaign began on 19th February 2007 and this paper reports the findings until 31st December 2007. The paper aims to share the experience gained with others who are considering or are already involved in similar campaigns and to enable opinions to be exchanged with those responsible for such campaigns in other countries. The campaign was initiated by the Spanish Ministry of Industry, Tourism and Trade with the expert assistance of the Nuclear Security Council. The initiative came about as a result of national legislation currently in force regarding the control of highly active and orphan radioactive source, which implements a European Directive. The campaign was commissioned to ENRESA (the Spanish National Company for Radioactive Waste Management) and the work, which began in 2007, will continue into 2008. The campaign aims to seek and recover the largest possible number of orphan radioactive sources (an Orphan radioactive source is understood to be one which is detected outside the standard control system and which, when detected, has an activity level higher than the exemption levels established in national and European regulations), and involves the collaboration of various different agents and organisations where such sources are or may be found. Finally, the paper provides details regarding the number and radiological characteristics of the sources which have already been recovered in Spain during the 2007 campaign. (author)

  9. Teachers’ Pastoral Role in Response to the Needs of Orphaned Learners

    Full Text Available This article discusses a study that explored the way teachers perceive and describe their roles in responding to the needs of orphaned learners. The participants in the study comprised three secondary and two primary school teachers. The data on the teachers’ experiences were collected through semi-structured interviews, and the findings revealed that, although some of the teachers attempted to fulfill some of the orphaned learners’ needs, most were unable to cope with the combined roles of teaching and learning and care giving. The study identified a lack of material, social, and emotional support for grieving learners. The findings indicate that there is a need for teacher development in terms of preparing teachers to provide pastoral care for orphaned learners. For the teachers’ efforts to be more fruitful, there is also an urgent need for supportive school leadership. In addition, the study highlights the need for counsellors and social workers to be appointed to work in collaboration with the teachers in providing for the needs of the learners.

  10. Could the Wein fireball be associated to the "orphan" TeV flares ?

    CERN Document Server

    Fraija, Nissim

    2015-01-01

    TeV $\\gamma$-ray detections in flaring states without activity in X-rays from blazars have attracted much attention due to the irregularity of these "orphan" flares. Although the synchrotron self-Compton model has been very successful in explaining the spectral energy distribution and spectral variability of these sources, it has not been able to describe these atypical flaring events. On the other hand, an electron-positron pair plasma at the base of the AGN jet was proposed as the mechanism of bulk acceleration of relativistic outflows. This plasma in quasi-themal equilibrium called Wein fireball emits radiation at MeV-peak energies serving as target of accelerated protons. In this work we describe the "orphan" TeV flares presented in blazars 1ES 1959+650 and Mrk421 assuming geometrical considerations in the jet and evoking the interactions of Fermi-accelerated protons and MeV-peak target photons coming from the Wein fireball. After describing successfully these "orphan" TeV flares, we correlate the TeV $\\g...

    2013-01-01

    We present candidate K-giant members in the Orphan Stream which have been identified from low-resolution data taken with the AAOmega spectrograph on the Anglo-Australian Telescope. From modest S/N spectra and independent cuts in photometry, kinematics, gravity and metallicity we yield self-consistent, highly probable stream members. We find a revised stream distance of 22.5 +/- 2.0 kpc near the celestial equator, and our kinematic signature peaks at Vgsr = 82.1 +/- 1.4 km/s. The observed velocity dispersion of our most probable members is consistent with arising from the velocity uncertainties alone. This indicates that at least along this line-of-sight, the Orphan Stream is kinematically cold. Our data indicates an overall stream metallicity of [Fe/H] = -1.63 +/- 0.19 dex which is more metal-rich than previously found and unbiased by spectral type. Furthermore, the significant metallicity dispersion displayed by our most probable members (0.56 dex) suggests that the unidentified Orphan Stream parent is a dSp...

    Full Text Available Abstract Orphans are an increasing problem in developing countries particularly in Africa; due to the HIV/AIDS pandemic; and needs collective effort in intervention processes by including all stakeholders right from the grass roots level. This paper attempts to present the role of traditional healers in psychosocial support for orphan children in Dar-es-Salaam City with special focus on those whose parents have died because of HIV/AIDS. Six traditional healers who were involved in taking care of orphans were visited at their "vilinge" (traditional clinics. In total they had 72 orphans, 31 being boys and 41 being girls with age range from 3 years to 19. It was learned that traditional healers, besides providing remedies for illnesses/diseases of orphans, they also provided other basic needs. Further, they even provided psychosocial support allowing children to cope with orphan hood life with ease. Traditional healers are living within communities at the grass roots level; and appear unnoticed hidden forces, which are involved in taking care of orphans. This role of traditional healers in taking care of orphans needs to be recognised and even scaling it up by empowering them both in financial terms and training in basic skills of psychosocial techniques in how to handle orphans, in order to reduce discrimination and stigmatisation in the communities where they live.

    2009-09-01

    Full Text Available Abstract Background This article is based on information collected about the situation of double orphans who are heading households in Rakai District, Uganda. The information will be used as justification and guidance for planning actions to improve the situation of these and similar children. This research is thus the first step in an Action Research approach leading to specific interventions. The aim of this article is to describe the situation of these orphaned children, with an emphasis on the psychosocial challenges they face. Methods The study involved interviews, focus group discussions, observations and narratives. Forty-three heads of sibling-headed households participated. Information derived from informal discussions with local leaders is also included. The responses were analyzed using a modified version of Giorgi's psychological phenomenological method as described by Malterud 1. Results Factors such as lack of material resources, including food and clothes, limited possibilities to attend school on a regular basis, vast responsibilities and reduced possibilities for social interaction all contribute to causing worries and challenges for the child heads of households. Most of the children claimed that they were stigmatized and, to a great extent, ignored and excluded from their community. The Local Council Secretary ("Chairman" seemed to be the person in the community most responsible and helpful, but some chairmen seemed not to care at all. The children requested counseling for themselves as well as for community members because they experienced lack of understanding from other children and from adult community members. Conclusion The children experienced their situation as a huge and complex problem for themselves as well as for people in their villages. However, the situation might improve if actions focused on practical and psychological issues as well as on sensitization about the children's situation could be initiated. In

  18. Excluding Orphan Drugs from the 340B Drug Discount Program: the Impact on 18 Critical Access Hospitals

    Directory of Open Access Journals (Sweden)

    Madeline Carpinelli Wallack

    2012-01-01

    Full Text Available Purpose: The 340B Drug Pricing Program is a federal program designed to reduce the amount that safety net providers spend on outpatient drugs. The Patient Protection and Affordable Health Care Act of 2010 extended eligibility for 340B to critical access hospitals (CAHs for all drugs except those designated as “orphan.” Because this policy is unprecedented, this study quantifies the gross financial impact that this exemption has on a group of CAHs. Methods: Drug spending for 2010 from 18 CAHs in Minnesota and Wisconsin are reviewed to identify the prevalence of orphan drug purchases and to calculate the price differentials between the 340B price and the hospitals’ current cost. Results: The 18 CAHs’ purchases of orphan drugs comprise an average of 44% of the total annual drug budgets, but only 5% of units purchased, thus representing a very high proportion of their expenditures. In the aggregate, the 18 hospitals would have saved $3.1 million ($171,000 average per hospital had purchases of drugs with orphan designations been made at the 340B price. Because CAH claims for Medicare are reimbursed on a cost-basis, the Federal government is losing an opportunity for savings. Conclusion: The high prevalence of orphan drug use and considerable potential for cost reduction through the 340B program demonstrate the loss of benefit to the hospitals, Federal government and the states.

  20. The Therapeutic Potential of Orphan GPCRs, GPR35 and GPR55

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available The G protein-coupled receptor (GPCR superfamily of integral proteins is the largest family of signal transducers, comprised of ~1000 members. Considering their prevalence and functional importance, it’s not surprising that ~60% of drugs target GPCRs. Regardless, there exists a subset of the GPCR superfamily that is largely uncharacterized and poorly understood; specifically, more than 140 GPCRs have unknown endogenous ligands—the so-called orphan GPCRs. Orphan GPCRs offer tremendous promise, as they may provide novel therapeutic targets that may be more selective than currently known receptors, resulting in the potential reduction in side effects. In addition, they may provide access to signal transduction pathways currently unknown, allowing for new strategies in drug design. Regardless, orphan GPCRs are an important area of inquiry, as they represent a large gap in our understanding of signal transduction at the cellular level. Here, we focus on the therapeutic potential of two recently-deorphanized GPCRs: GPR35/CXCR8 and GPR55. First, GPR35/CXCR8 has been observed in numerous tissues/organ systems, including the gastrointestinal tract, liver, immune system, central nervous system, and cardiovascular system. Not surprisingly, GPR35/CXCR8 has been implicated in numerous pathologies involving these tissues/systems. While several endogenous ligands have been identified, GPR35/CXCR8 has recently been observed to bind the chemokine CXCL17. Second, GPR55 has been observed to be expressed in the central nervous system, adrenal glands, gastrointestinal tract, lung, liver, uterus, bladder, kidney and bone, as well as, other tissues/organ systems. Likewise, it is not surprising that GPR55 has been implicated in pathologies involving these tissues/systems. GPR55 was initially deorphanized as a cannabinoid receptor and this receptor does bind many cannabinoid compounds. However, the GPR55 endogenous ligand has been found to be a non

  1. The Orphan Gene dauerless Regulates Dauer Development and Intraspecific Competition in Nematodes by Copy Number Variation.

    Mayer, Melanie G; Rödelsperger, Christian; Witte, Hanh; Riebesell, Metta; Sommer, Ralf J

    2015-06-01

    Many nematodes form dauer larvae when exposed to unfavorable conditions, representing an example of phenotypic plasticity and a major survival and dispersal strategy. In Caenorhabditis elegans, the regulation of dauer induction is a model for pheromone, insulin, and steroid-hormone signaling. Recent studies in Pristionchus pacificus revealed substantial natural variation in various aspects of dauer development, i.e. pheromone production and sensing and dauer longevity and fitness. One intriguing example is a strain from Ohio, having extremely long-lived dauers associated with very high fitness and often forming the most dauers in response to other strains' pheromones, including the reference strain from California. While such examples have been suggested to represent intraspecific competition among strains, the molecular mechanisms underlying these dauer-associated patterns are currently unknown. We generated recombinant-inbred-lines between the Californian and Ohioan strains and used quantitative-trait-loci analysis to investigate the molecular mechanism determining natural variation in dauer development. Surprisingly, we discovered that the orphan gene dauerless controls dauer formation by copy number variation. The Ohioan strain has one dauerless copy causing high dauer formation, whereas the Californian strain has two copies, resulting in strongly reduced dauer formation. Transgenic animals expressing multiple copies do not form dauers. dauerless is exclusively expressed in CAN neurons, and both CAN ablation and dauerless mutations increase dauer formation. Strikingly, dauerless underwent several duplications and acts in parallel or downstream of steroid-hormone signaling but upstream of the nuclear-hormone-receptor daf-12. We identified the novel or fast-evolving gene dauerless as inhibitor of dauer development. Our findings reveal the importance of gene duplications and copy number variations for orphan gene function and suggest daf-12 as major target for

    Orphan Basin is located on the eastern margin of Canada, offshore of Newfoundland and East of Flemish Cap. It is an aborted continental rift formed by multiple episodes of rifting. The crustal structure across the basin has been determined by an earlier refraction study using 15 instruments on a 550 km long line. It shows that the continental crust was extended over an unusually wide region but did not break apart. The crustal structure of the basin thus documents stages in the formation of a magma-poor rifted margin up to crustal breakup. The OBWAVE (Orphan Basin Wide-Angle Velocity Experiment) survey was carried out to image crustal structures across the basin and better understand the processes of formation of this margin. The spacing of the 89 recording stations varies from 3 to 5 km along this 500-km-long line, which was acquired along a pre-existing reflection line. The highest resolution section corresponds to the part of the profile where the crust was expected to be the thinnest. We present the results from a joint tomography inversion of first and Moho reflected arrival times. The high data density allows us to define crustal structures with greater detail than for typical studies and to improve the understanding of the processes leading to the extreme stretching of continental crust. The final model was computed following a detailed parametric study to determine the optimal parameters controlling the ray-tracing and the inversion processes. The final model shows very good resolution. In particular, Monte Carlo standard deviations of crustal velocities and Moho depths are generally Orphan Basin is the result of rifting of a non-homogeneous Avalon terrane where the lower crust is primarily ductile.

  4. The human orphan nuclear receptor tailless (TLX, NR2E1 is druggable.

    Directory of Open Access Journals (Sweden)

    Cindy Benod

    Full Text Available Nuclear receptors (NRs are an important group of ligand-dependent transcriptional factors. Presently, no natural or synthetic ligand has been identified for a large group of orphan NRs. Small molecules to target these orphan NRs will provide unique resources for uncovering regulatory systems that impact human health and to modulate these pathways with drugs. The orphan NR tailless (TLX, NR2E1, a transcriptional repressor, is a major player in neurogenesis and Neural Stem Cell (NSC derived brain tumors. No chemical probes that modulate TLX activity are available, and it is not clear whether TLX is druggable. To assess TLX ligand binding capacity, we created homology models of the TLX ligand binding domain (LBD. Results suggest that TLX belongs to an emerging class of NRs that lack LBD helices α1 and α2 and that it has potential to form a large open ligand binding pocket (LBP. Using a medium throughput screening strategy, we investigated direct binding of 20,000 compounds to purified human TLX protein and verified interactions with a secondary (orthogonal assay. We then assessed effects of verified binders on TLX activity using luciferase assays. As a result, we report identification of three compounds (ccrp1, ccrp2 and ccrp3 that bind to recombinant TLX protein with affinities in the high nanomolar to low micromolar range and enhance TLX transcriptional repressive activity. We conclude that TLX is druggable and propose that our lead compounds could serve as scaffolds to derive more potent ligands. While our ligands potentiate TLX repressive activity, the question of whether it is possible to develop ligands to de-repress TLX activity remains open.

    The orphan nuclear receptor hepatocyte nuclear factor 4 (HNF-4) is required for development and maintenance of the liver phenotype. HNF-4 activates several hepatocyte-specific genes, including the gene encoding apolipoprotein AI (apoAI), the major protein component of plasma high-density lipoprotein. The apoAI gene is activated by HNF-4 through a nuclear receptor binding element (site A) located in its liver-specific enhancer. To decipher the mechanism whereby HNF-4 enhances apoAI gene transc...

    Testicular receptors 2 and 4 (TR2/4) constitute a subgroup of orphan nuclear receptors that play important roles in spermatogenesis, lipid and lipoprotein regulation, and the development of the central nervous system. Currently, little is known about the structural features and the ligand regulation of these receptors. Here we report the crystal structure of the ligand-free TR4 ligand binding domain, which reveals an autorepressed conformation. The ligand binding pocket of TR4 is filled by the C-terminal half of helix 10, and the cofactor binding site is occupied by the AF-2 helix, thus preventing ligand-independent activation of the receptor. However, TR4 exhibits constitutive transcriptional activity on multiple promoters, which can be further potentiated by nuclear receptor coactivators. Mutations designed to disrupt cofactor binding, dimerization, or ligand binding substantially reduce the transcriptional activity of this receptor. Importantly, both retinol and retinoic acid are able to promote TR4 to recruit coactivators and to activate a TR4-regulated reporter. These findings demonstrate that TR4 is a ligand-regulated nuclear receptor and suggest that retinoids might have a much wider regulatory role via activation of orphan receptors such as TR4.

    2015-01-01

    We verified the off-axis jet model of X-ray flashes (XRFs) and examined a discovery of off-axis orphan gamma-ray burst (GRBs) afterglows. The XRF sample was selected on the basis of the following three factors: (1) a constraint on the lower peak energy of the prompt spectrum $E^{src}_{obs}$, (2) redshift measurements, and (3) multi-color observations of an earlier (or brightening) phase. XRF020903 was the only sample selected basis of these criteria. A complete optical multi-color afterglow light curve of XRF020903 obtained from archived data and photometric results in literature showed an achromatic brightening around 0.7 days. An off-axis jet model with a large observing angle (0.21 rad, which is twice the jet opening half-angle, $\\theta_{jet}$) can naturally describe the achromatic brightening and the prompt X-ray spectral properties. This result indicates the existence of off-axis orphan GRB afterglow light curves. Events with a larger viewing angle ($>\\sim2\\theta_{jet}$) could be discovered using an 8-m ...

    The sealed radioactive sources are widely applicable in industry. They must have a permanent control and must be registered with the Technical Office of the National Authority (OTAN). However, at times it has identified the presence of abandoned sealed sources unknown to the owner. These sources are called 'orphan sources'. Of course these sources represent a high potential risk because accidents can trigger dire consequences depending on your activity and chemical form in which it presents the radioisotope. This paper describes the process and the actions taken to characterize two orphan radioactive sources from the smelter a Aceros Arequipa. For characterization we used a gamma spectrometry system using a detector NaI(Tl) 3″ x 3″ with a multichannel analyzer Nucleus PCA-II. The radioisotope identified was cesium - 137 ({sup 137}Cs) in both cases. Fortunately, the sources maintained their integrity would otherwise have generated significant pollution considering the chemical form of the radioisotope and easy dispersion. (author)

  19. Analysis of in planta Expressed Orphan Genes in the Rice Blast Fungus Magnaporthe oryzae

    Full Text Available Genomes contain a large number of unique genes which have not been found in other species. Although the origin of such “orphan” genes remains unclear, they are thought to be involved in species-specific adaptive processes. Here, we analyzed seven orphan genes (MoSPC1 to MoSPC7 prioritized based on in planta expressed sequence tag data in the rice blast fungus, Magnaporthe oryzae. Expression analysis using qRT-PCR confirmed the expression of four genes (MoSPC1, MoSPC2, MoSPC3 and MoSPC7 during plant infection. However, individual deletion mutants of these four genes did not differ from the wild-type strain for all phenotypes examined, including pathogenicity. The length, GC contents, codon adaptation index and expression during mycelial growth of the four genes suggest that these genes formed during the evolutionary history of M. oryzae. Synteny analyses using closely related fungal species corroborated the notion that these genes evolved de novo in the M. oryzae genome. In this report, we discuss our inability to detect phenotypic changes in the four deletion mutants. Based on these results, the four orphan genes may be products of de novo gene birth processes, and their adaptive potential is in the course of being tested for retention or extinction through natural selection.

    A recurrent t(9;22) (q22;q12) chromosome translocation has been described in extraskeletal myxoid chondrosarcoma (EMC). Fluorescent in situ hybridization experiments performed on one EMC tumour indicated that the chromosome 22 breakpoint occurred in the EWS gene. Northern blot analysis revealed an aberrant EWS transcript which is cloned by a modified RT-PCR procedure. This transcript consists of an in-frame fusion of the 5' end of EWS to a previously unidentified gene, which was named TEC. This fusion transcript was detected in six of eight EMC studied, and three different junction types between the two genes were found. In all junction types, the putative translation product contained the amino-terminal transactivation domain of EWS linked to the entire TEC protein. Homology analysis showed that the predicted TEC protein contains a DNA-binding domain characteristic of nuclear receptors. The highest identity scores were observed with the NURR1 family of orphan nuclear receptors. These receptors are involved in the control of cell proliferation and differentiation by modulating the response to growth factors and retinoic acid. This work provides, after the PML/RAR alpha gene fusion, the second example of the oncogenic conversion of a nuclear receptor and the first example involving the orphan subfamily. Analysis of the disturbance induced by the EWS/TEc protein in the nuclear receptor network and their target genes may lead to new approaches for EMC treatment. PMID:8634690

    The SLC43 family is composed of only three genes coding for the plasma membrane facilitator system l amino acid transporters LAT3 (SLC43A1; TC 2.A.1.44.1) and LAT4 (SLC43A2; TC 2.A.1.44.2), and the orphan protein EEG1 (SLC43A3; TC 2.A.1.44.3). Besides the known mechanism of transport of LAT3 and LAT4, their physiological roles still remain quite obscure. Morphants suggested a role of LAT3 in renal podocyte development in zebrafish. Expression in liver and skeletal muscle, and up-regulation by starvation suggest a role of LAT3 in the flux of branched-chain amino acids (BCAAs) from liver and skeletal muscle to the bloodstream. Finally, LAT3 is up-regulated in androgen-dependent cancers, suggesting a role in mTORC1 signaling in this type of tumors. In addition, LAT4 might contribute to the transfer of BCAAs from mother to fetus. Unfortunately, the EEG1 mouse model (EEG1(Y221∗)) described here has not yet offered a clue to the physiological role of this orphan protein.

    Low- and middle-income countries have a high number of orphans, many of whom have unmet mental health needs. Effective mental health interventions are needed; however, it is necessary to understand how mental health symptoms and needs are perceived locally to tailor interventions and refine measurement of intervention effects. We used an existing rapid ethnographic assessment approach to identify mental health problems from the perspective of orphans and guardians to inform a subsequent randomized controlled trial of a Western-developed, evidence-based psychosocial intervention, Trauma-focused Cognitive Behavioral Therapy. Local Kiswahili-speaking interviewers conducted 73 free list interviews and 34 key informant interviews. Results identified both common cross-cultural experiences and symptoms as well as uniquely described symptoms (e.g., lacking peace, being discriminated against) not typically targeted by the intervention or included on standardized measures of intervention effects. We discuss implications for adapting mental health interventions in low- and middle-income countries and assessing effectiveness. PMID:26488916

    Nurr1/NR4A2 is an orphan nuclear receptor, and currently there are no known natural ligands that bind Nurr1. A recent metabolomics study identified unsaturated fatty acids, including arachidonic acid and docosahexaenoic acid (DHA), that interact with the ligand-binding domain (LBD) of a related orphan receptor, Nur77/NR4A1. However, the binding location and whether these ligands bind other NR4A receptors were not defined. Here, we show that unsaturated fatty acids also interact with the Nurr1 LBD, and solution NMR spectroscopy reveals the binding epitope of DHA at its putative ligand-binding pocket. Biochemical assays reveal that DHA-bound Nurr1 interacts with high affinity with a peptide derived from PIASγ, a protein that interacts with Nurr1 in cellular extracts, and DHA also affects cellular Nurr1 transactivation. This work is the first structural report of a natural ligand binding to a canonical NR4A ligand-binding pocket and indicates a natural ligand can bind and affect Nurr1 function. PMID:27128111

  5. X-RAY OBSERVATIONS OF DISRUPTED RECYCLED PULSARS: NO REFUGE FOR ORPHANED CENTRAL COMPACT OBJECTS

    International Nuclear Information System (INIS)

    We present a Chandra X-ray survey of the disrupted recycled pulsars (DRPs), isolated radio pulsars with P > 20 ms and Bs 10 G. These observations were motivated as a search for the immediate descendants of the ≈10 central compact objects (CCOs) in supernova remnants (SNRs), 3 of which have similar timing and magnetic properties as the DRPs, but are bright, thermal X-ray sources consistent with minimal neutron star (NS) cooling curves. Since none of the DPRs were detected in this survey, there is no evidence that they are ''orphaned'' CCOs, NSs whose SNRs has dissipated. Upper limits on their thermal X-ray luminosities are in the range of log Lx [erg s–1] = 31.8-32.8, which implies cooling ages >104-105 yr, roughly 10 times the ages of the ≈10 known CCOs in a similar volume of the Galaxy. The order of a hundred CCO descendants that could be detected by this method are thus either intrinsically radio quiet or occupy a different region of (P, Bs ) parameter space from the DRPs. This motivates a new X-ray search for orphaned CCOs among radio pulsars with larger B-fields, which could verify the theory that their fields are buried by the fall-back of supernova ejecta, but quickly regrow to join the normal pulsar population

    Brown adipocytes increase energy production in response to induction of PGC-1alpha, a dominant regulator of energy metabolism. We have found that the orphan nuclear receptor SHP (NR0B2) is a negative regulator of PGC-1alpha expression in brown adipocytes. Mice lacking SHP show increased basal expression of PGC-1alpha, increased energy expenditure, and resistance to diet-induced obesity. Increased PGC-1alpha expression in SHP null brown adipose tissue is not due to beta-adrenergic activation, since it is also observed in primary cultures of SHP(-/-) brown adipocytes that are not exposed to such stimuli. In addition, acute inhibition of SHP expression in cultured wild-type brown adipocytes increases basal PGC-1alpha expression, and SHP overexpression in SHP null brown adipocytes decreases it. The orphan nuclear receptor ERRgamma is expressed in BAT and its transactivation of the PGC-1alpha promoter is potently inhibited by SHP. We conclude that SHP functions as a negative regulator of energy production in BAT.

  7. Trends in individual reimbursement of orphan drugs in Latvia in 2008–2011

    Directory of Open Access Journals (Sweden)

    Logviss K.

    2014-01-01

    Full Text Available Orphan drugs (ODs are medicinal products intended for diagnosis, prevention or treatment of life-threatening or very serious diseases affecting less than 5 in 10 000 people in the European Union (EU. These drugs are called “orphans” because the pharmaceutical industry has little interest, under normal market conditions, in developing and marketing products intended for only a small number of patients suffering from very rare conditions. Because of the small market, ODs are often very expensive. Whereas decisions surrounding orphan designation and marketing authorization of ODs are taken at the EU level, decisions governing pricing and reimbursement of ODs are a member state responsibility. In Latvia drug reimbursement covers drugs which are included in the national reimbursement drug list or, based on the medical council's decision, drugs can also be reimbursed within the framework of individual reimbursement system with limit of 10 000 LVL (€ 14 229 per patient per year. Due to the big costs and the small number of patients ODs are often not included in the reimbursement list and therefore are reimbursed individually.

  8. The influence of orphan care and other household shocks on health status over time: a longitudinal study of children's caregivers in rural Malawi.

    2011-12-01

    In the context of rising rates of orphanhood in AIDS-affected settings, very little is understood about implications for caregiver well-being given increasing and intensifying responsibilities for the care of orphaned children. Emotional distress and self-reported health status as well as shifts in household orphan care, wealth, food security and recent illness and death among household members were measured among a panel of 1219 caregivers in rural Malawi between 2007 and 2009. Logistic regression was used to identify predictors of improved and diminished caregiver health and emotional distress. Results suggest that becoming an orphan caregiver is associated with a shift from good to poor health status (adjusted odds ratio [AOR]=2.29, 95% confidence interval [CI]=1.16-4.54), and that elevated levels of distress and poor health both persist over time in comparison with care for non-orphans only. Once engaged in orphan care, taking on additional orphans is associated with increased emotional distress in relation to not caring for orphans (AOR=3.16, 95% CI=1.30-7.73) as well as in relation to maintaining the same number of orphans in care over time (AOR=2.84, 95% CI=1.04-7.70). In addition, findings illustrate the strong influence of household wealth and food security on caregiver well-being. Food insecurity and poverty that persist or develop over time are associated with increasing distress. Conversely, maintenance or improvement in food security and household wealth are associated with decreases in distress. Providing all aspects of household maintenance and care for children, primary caregivers are key to the extended family solution for orphaned and vulnerable children. Bolstering the foundation of rural African families to ensure care and protection of these children involves targeting support to orphan caregivers but must also include addressing the issues of poverty and food insecurity that pose a wider threat to caregiving capacity.

  9. Who Owns Child Abuse?

    OpenAIRE

    Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement.

    not allow to accurately estimating those children and adolescents living with HIV and non-orphans affected by HIV/AIDS but data was available on those living with AIDS and orphans. The limitations and possibilities of these estimates obtained from surveillance systems, mathematical models and surveys are discussed. Though studies in literature are still quite scarce, there is indication of compromise of several rights such as health, education, housing, nutrition, nondiscrimination, and physical and mental integrity. Brazil still needs to advance to meet further needs of those orphaned and vulnerable children. Its response so far has been limited to providing health care to those children and adolescents living with HIV/AIDS, preventing mother-to-child HIV transmission and financing the implementation and maintenance of support homes (shelters according to Child and Adolescent Bill of Rights for those infected and affected by HIV/AIDS, either orphans or not. These actions are not enough to ensure a supportive environment for children and adolescents orphaned, infected or affected by HIV/AIDS. It is proposed ways for Brazil to develop and improve databases to respond to these challenges.

    In recent years carborne gamma spectrometry has expanded from its role as a geological survey platform to serving as a useful asset in the field of emergency response to radiological and nuclear situations. Its two main applications are searching for orphan sources and for surveying in the aftermath of an accident involving the release of radioactive materials. Despite this expansion, the opportunities for gaining practical experience in the field are limited by cost considerations and practicability. These limitations are exacerbated by the fact that data generated and displayed in the field differ significantly from gamma spectral data generated in a laboratory environment. As a means of exercising existing emergency measuring/surveying capability and introducing carborne measurements to a larger group, a virtual exercise was devised. The exercise ORPEX (Orphan Sources and Fresh Fallout Virtual Exercise in Mobile Measurement) featured two typical emergency scenarios in which carborne measuring systems might be deployed: firstly a search for multiple orphan sources and secondly surveying to delineate patchy fallout from a local release point. In the first scenario, synthetic spectral data were generated for imaginary point sources and inserted into genuine carborne measurements from in the Trondheim area of Norway. Participants were presented with a typical software tool and data in a range of typical formats and asked to report the source locations and isotopes within a time limit. In the second scenario, synthetic spectral data representing fallout from a local fire involving radioactive material were added to real carborne data from the Trondheim area. Participants were asked to produce maps that identify and characterise the regions of contamination within the same time limit. Fourteen individual organisations from seven different countries supplied results. Results from participants indicate that for strong sources of isotopes with simple spectra featuring

  20. Rates and risks for prolonged grief disorder in a sample of orphaned and widowed genocide survivors

    Full Text Available Abstract Background The concept of Prolonged Grief Disorder (PGD has been defined in recent years by Prigerson and co-workers, who have developed and empirically tested consensus and diagnostic criteria for PGD. Using these most recent criteria defining PGD, the aim of this study was to determine rates of and risks for PGD in survivors of the 1994 Rwandan genocide who had lost a parent and/or the husband before, during or after the 1994 events. Methods The PG-13 was administered to 206 orphans or half orphans and to 194 widows. A regression analysis was carried out to examine risk factors of PGD. Results 8.0% (n = 32 of the sample met criteria for PGD with an average of 12 years post-loss. All but one person had faced multiple losses and the majority indicated that their grief-related loss was due to violent death (70%. Grief was predicted mainly by time since the loss, by the violent nature of the loss, the severity of symptoms of posttraumatic stress disorder (PTSD and the importance given to religious/spiritual beliefs. By contrast, gender, age at the time of bereavement, bereavement status (widow versus orphan, the number of different types of losses reported and participation in the funeral ceremony did not impact the severity of prolonged grief reactions. Conclusions A significant portion of the interviewed sample continues to experience grief over interpersonal losses and unresolved grief may endure over time if not addressed by clinical intervention. Severity of grief reactions may be associated with a set of distinct risk factors. Subjects who lose someone through violent death seem to be at special risk as they have to deal with the loss experience as such and the traumatic aspects of the loss. Symptoms of PTSD may hinder the completion of the mourning process. Religious beliefs may facilitate the mourning process and help to find meaning in the loss. These aspects need to be considered in the treatment of PGD.

    2005-08-01

    Full Text Available Abstract Background The cell-membrane G-protein coupled receptors (GPCRs are one of the largest known superfamilies and are the main focus of intense pharmaceutical research due to their key role in cell physiology and disease. A large number of putative GPCRs are 'orphans' with no identified natural ligands. The first step in understanding the function of orphan GPCRs is to identify their ligands. Phylogenetic clustering methods were used to elucidate the chemical nature of receptor ligands, which led to the identification of natural ligands for many orphan receptors. We have clustered human and Drosophila receptors with known ligands and orphans through cross genome phylogenetic analysis and hypothesized higher relationship of co-clustered members that would ease ligand identification, as related receptors share ligands with similar structure or class. Results Cross-genome phylogenetic analyses were performed to identify eight major groups of GPCRs dividing them into 32 clusters of 371 human and 113 Drosophila proteins (excluding olfactory, taste and gustatory receptors and reveal unexpected levels of evolutionary conservation across human and Drosophila GPCRs. We also observe that members of human chemokine receptors, involved in immune response, and most of nucleotide-lipid receptors (except opsins do not have counterparts in Drosophila. Similarly, a group of Drosophila GPCRs (methuselah receptors, associated in aging, is not present in humans. Conclusion Our analysis suggests ligand class association to 52 unknown Drosophila receptors and 95 unknown human GPCRs. A higher level of phylogenetic organization was revealed in which clusters with common domain architecture or cellular localization or ligand structure or chemistry or a shared function are evident across human and Drosophila genomes. Such analyses will prove valuable for identifying the natural ligands of Drosophila and human orphan receptors that can lead to a better understanding

    Retinoic acid receptor (RAR)-related orphan receptors (RORs) regulate a variety of physiological processes, including hepatic gluconeogenesis, lipid metabolism, circadian rhythm and immune function. The RAR agonist: all-trans retinoic acid was reported to be an RORβ inverse agonist, but no information is available regarding ROR activity of its synthetic analogue Am580. Therefore, we screened Am580 and some related tetramethyltetrahydronaphthalene derivatives and carried out structural development studies, including substitution of carbon atoms with silicon, with the aim of creating a potent ROR transcriptional inhibitor. The phenyl amide disila compound 22 showed the most potent ROR-inhibitory activity among the compounds examined. Its activity towards RORα, RORβ and RORγ was increased compared to that of Am580. The IC₅₀ values for RORα, RORβ and RORγ are 1.3, >10 and 4.5 μM, respectively.

    We have constructed a unique instrument for use in the search for orphan sources. The system uses gamma-ray imaging to "see through" the natural background variations that effectively limit the search range of normal devices to ~10 m. The imager is mounted in a 4.9- m-long trailer and can be towed by a large personal vehicle. Source locations are determined both in range and along the direction of travel as the vehicle moves. A fully inertial platform coupled to a Global Positioning System receiver is used to map the gamma-ray images onto overhead geospatial imagery. The resulting images provide precise source locations, allowing rapid follow-up work. The instrument simultaneously searches both sides of the street to a distance of 50 m (100-m swath) for milliCurieclass sources with near-perfect performance.

    Orphan diseases are not a common challenge in the everyday practice of the rheumatologist. Despite their extremely rare occurrence one of the patients under our care developed one of them - neuronal ceroid lipofuscinosis, the most frequent neurodegenerative disease observed in the paediatric population. We report a case of 2-year-old girl diagnosed with oligoarticular form of juvenile idiopathic arthritis treated in our Department with steroids and methotrexate and staying in the stage of disease remission. During routine checkups at Outpatient Clinic we observed progressive deterioration of girls neurological condition resulting in ataxia, gait disturbances with no rheumatological cause behind and speech impairment. The appearance of the symptoms was accompanied by frequent episodes of epileptic seizures, with little clinical improvement on combined antiepileptic treatment. Magnetic resonance imaging that we performed showed a picture highly suggestive of neuronal ceroid lipofuscinosis - atrophy of the patients cerebrum and cerebellum. Genetic testing conducted resulted in the diagnosis of late infantile neuronal ceroid lipofuscinosis (LINCL). PMID:27504025

    We present a Chandra X-ray survey of the disrupted recycled pulsars (DRPs), isolated radio pulsars with P > 20 ms and B_s 1E4 - 1E5 yr, roughly 10 times the ages of the approximately 10 known CCOs in a similar volume of the Galaxy. The order of a hundred CCO descendants that could be detected by this method are thus either intrinsically radio quiet, or occupy a different region of (P,B_s) parameter space from the DRPs. This motivates a new X-ray search for orphaned CCOs among radio pulsars with larger B-fields, which could verify the theory that their fields are buried by fall-back of supernova ejecta, but quickly regrow to join the normal pulsar population.

    The retinoic acid-related orphan receptor {gamma} (ROR{gamma}) has important roles in development and metabolic homeostasis. Although the biological functions of ROR{gamma} have been studied extensively, no ligands for ROR{gamma} have been identified, and no structure of ROR{gamma} has been reported. In this study, we showed that hydroxycholesterols promote the recruitment of coactivators by ROR{gamma} using biochemical assays. We also report the crystal structures of the ROR{gamma} ligand-binding domain bound with hydroxycholesterols. The structures reveal the binding modes of various hydroxycholesterols in the ROR{gamma} pocket, with the receptors all adopting the canonical active conformation. Mutations that disrupt the binding of hydroxycholesterols abolish the constitutive activity of ROR{gamma}. Our observations suggest an important role for the endogenous hydroxycholesterols in modulating ROR{gamma}-dependent biological processes.

    A significant proportion of coding sequences or open reading frames discovered in the course of sequencing projects do not show any similarity with other sequences deposited with the protein databanks. In such cases the search for similarities must be performed with as many comparison algorithms as possible, so as to increase the chance of finding weak relationships. A specialised parallel hardware (SAMBA) implementing the Smith & Waterman algorithm has been developed at the 'Institut de Recherche en Informatique et Systèmes Aléatoìres' (IRISA). It makes it possible to scan protein databanks at a speed comparable with that of BLAST or FASTA. We report here a study performed with SAMBA on 814 orphan sequences from S cerevisiae and compare the results with those from BLAST and FASTA.

  12. An orphan gene is necessary for preaxial digit formation during salamander limb development

    Kumar, Anoop; Gates, Phillip B.; Czarkwiani, Anna; Brockes, Jeremy P.

    2015-01-01

    Limb development in salamanders differs from other tetrapods in that the first digits to form are the two most anterior (preaxial dominance). This has been proposed as a salamander novelty and its mechanistic basis is unknown. Salamanders are the only adult tetrapods able to regenerate the limb, and the contribution of preaxial dominance to limb regeneration is unclear. Here we show that during early outgrowth of the limb bud, a small cohort of cells express the orphan gene Prod1 together with Bmp2, a critical player in digit condensation in amniotes. Disruption of Prod1 with a gene-editing nuclease abrogates these cells, and blocks formation of the radius and ulna, and outgrowth of the anterior digits. Preaxial dominance is a notable feature of limb regeneration in the larval newt, but this changes abruptly after metamorphosis so that the formation of anterior and posterior digits occurs together within the autopodium resembling an amniote-like pattern.

    This cost-effectiveness study analyzes the cost per quality-adjusted life year (QALY) gained in a randomized controlled trial that tested school support as a structural intervention to prevent HIV risk factors among Zimbabwe orphan girl adolescents. The intervention significantly reduced early marriage, increased years of schooling completed, and increased health-related quality of life. By reducing early marriage, the literature suggests the intervention reduced HIV infection. The intervention yielded an estimated US$1,472 in societal benefits and an estimated gain of 0.36 QALYs per orphan supported. It cost an estimated US$6/QALY gained, about 1 % of annual per capita income in Zimbabwe. That is well below the maximum price that the World Health Organization (WHO) Commission on Macroeconomics and Health recommends paying for health gains in low and middle income countries. About half the girls in the intervention condition were boarded when they reached high school. For non-boarders, the intervention's financial benefits exceeded its costs, yielding an estimated net cost savings of $502 per pupil. Without boarding, the intervention would yield net savings even if it were 34 % less effective in replication. Boarding was not cost-effective. It cost an additional $1,234 per girl boarded (over the 3 years of the study, discounted to present value at a 3 % discount rate) but had no effect on any of the outcome measures relative to girls in the treatment group who did not board. For girls who did not board, the average cost of approximately 3 years of school support was US$973. PMID:23334923

    Full Text Available Eline Picavet,1 David Cassiman,2 Steven Simoens1 1Department of Pharmaceutical and Pharmacological Sciences, KU Leuven, Leuven, Belgium; 2Department of Hepatology, University Hospital Leuven, Leuven, Belgium Abstract: Ultra-orphan medicinal products (ultra-OMPs are intended for the treatment, prevention, or diagnosis of ultra-rare diseases, ie, life-threatening or chronically debilitating diseases that affect less than one per 50,000 individuals. Recently, high prices for ultra-OMPs have given rise to debate on the sustainability and justification of these prices. The aim of this article is to review the international scientific literature on the pricing of ultra-OMPs and to provide an overview of the current knowledge on the drivers of ultra-OMP pricing. The pricing process of ultra-OMPs is a complex and nontransparent issue. Evidence in the literature seems to indicate that ultra-OMPs are priced according to rarity and what the manufacturer believes the market will bear. Additionally, there appears to be a trend between the price of an ultra-OMP and the number of available alternatives. Patients, third-party payers, and pharmaceutical companies could benefit from more transparent pricing strategies. With a view to containing health care costs, it is likely that cost-sharing strategies, such as performance-based risk sharing arrangements, will become increasingly more important. However, it is vital that any measures for price control are consistent with the intended goals of the incentives to promote the development of new OMPs. Ideally, a balance must be struck between attaining affordable prices for ultra-OMPs and securing a realistic return on investment for the pharmaceutical industry.

  15. QQS orphan gene regulates carbon and nitrogen partitioning across species via NF-YC interactions.

    The allocation of carbon and nitrogen resources to the synthesis of plant proteins, carbohydrates, and lipids is complex and under the control of many genes; much remains to be understood about this process. QQS (Qua-Quine Starch; At3g30720), an orphan gene unique to Arabidopsis thaliana, regulates metabolic processes affecting carbon and nitrogen partitioning among proteins and carbohydrates, modulating leaf and seed composition in Arabidopsis and soybean. Here the universality of QQS function in modulating carbon and nitrogen allocation is exemplified by a series of transgenic experiments. We show that ectopic expression of QQS increases soybean protein independent of the genetic background and original protein content of the cultivar. Furthermore, transgenic QQS expression increases the protein content of maize, a C4 species (a species that uses 4-carbon photosynthesis), and rice, a protein-poor agronomic crop, both highly divergent from Arabidopsis. We determine that QQS protein binds to the transcriptional regulator AtNF-YC4 (Arabidopsis nuclear factor Y, subunit C4). Overexpression of AtNF-YC4 in Arabidopsis mimics the QQS-overexpression phenotype, increasing protein and decreasing starch levels. NF-YC, a component of the NF-Y complex, is conserved across eukaryotes. The NF-YC4 homologs of soybean, rice, and maize also bind to QQS, which provides an explanation of how QQS can act in species where it does not occur endogenously. These findings are, to our knowledge, the first insight into the mechanism of action of QQS in modulating carbon and nitrogen allocation across species. They have major implications for the emergence and function of orphan genes, and identify a nontransgenic strategy for modulating protein levels in crop species, a trait of great agronomic significance.

  20. Who Owns Child Abuse?

    Directory of Open Access Journals (Sweden)

    Gerald Cradock

    2014-11-01

    Full Text Available Expectations of contemporary child protection apparatuses are strongly influenced by beliefs inherited from the nineteenth century child rescue movement. In particular, the belief that child abuse determination is obvious. However, this assumption fails to make a distinction between nineteenth century’s emphasis on impoverished environments and the twentieth century introduction of the pathological child abuser. Moreover, the proliferation of kinds of child abuse, and the need to distinguish child abusers from non-abusers, means knowledge is now spread across an array of disciplines and professions, which necessarily destabilizes the definition of child abuse. The increasing exposure of alternate care systems as potentially abusive has similarly destabilized the old common sense solution to neglected children—namely removal. Finally, as uncertainty increases, and definitions become more divergent, the question of what child abuse is, and what should be done about it, becomes increasingly politicized.

    1982-09-01

    Even though Malaysia is a relatively prosperous country amongst the developing nations, it is still be set by problems of a rapidly increasing population. The economic cake is also unevenly distributed and there are pockets of poverty in the slums surrounding the towns as well as in the rural areas. Added to that is the problem of ignorance and superstition especially amongst its adult population. It is due to these problems that the Child-to-Child programme has found special application in Malaysia. The Child-to-Child has been introduced through either the government agencies or the voluntary organizations. Through the Ministry of Education, the concept has found its ways through the schools and the state department of education. The Ministry of Information and Broadcasting has also introduced the concept of Child-to-Child in the media. The voluntary organizations have also introduced the concept of Child-to-Child in their projects. The Sang Kancil project has to some extent used the idea in the running of its activities. The Health and Nutrition Education House have found that by applying the concept and using older children to help in running its activities, its over all objective which is the improvement of the health of the children in the slums could be reached more easily.

    2015-12-01

    Competence is a vital component of the informed consent process. The perceived level of a child's competence may influence their degree of participation in health decisions that affect them. It is the responsibility of the health professional to gauge a child's level of competence. Child competence, however, is not a static attribute that is linked to age. Rather, it is dynamic, changing in nature and dependent on a child's previous experiences, personal attributes, network of relationships around them and cultural and environmental context. Consequently, there is no single verified assessment tool to assist in the recognition of competence for New Zealand children. Adding to this complexity are the unclear interpretations of New Zealand health legislation and policy regarding whether or not a child can legally consent or refuse healthcare advice and treatment without the consent of a legal guardian. Under the Care of Children Act 2004 and the Code of Health and Disability Services Consumers' Rights 1996, the Health and Disability Commissioner states "a child may consent themselves [to health treatment] if and when the child achieves sufficient understanding and maturity to understand fully what is proposed". This paper poses the question: What is 'competency' and how is this decided? For the purpose of this article, 'child' pertains to those under the age of 16 years. PMID:26913912

    The fostering of an autistic child deemed to be a child at risk leads one to question one's professional practices. In a children's home, an approach guided by psychoanalysis can recognise the benefits of behavioural or cognitive approaches. The aim of the professional's particular educational position is therefore to construct a relationship with each child.

  9. From child to child: children as communicators.

    Science.gov (United States)

    Phinney, R; Evans, J

    1993-01-01

    Older children commonly care for their younger siblings while parents work to provide for the household. Through play, dance, and talk, children tend to interact with each other more intensely than do adults. In so doing, messages and awareness are exchanged more effectively. Child-to-Child is an active, child-centered learning approach which aims to capitalize on this phenomenon by training older siblings to be effective communicators. This approach has been formally practiced in over 70 countries since 1979. Child-to-Child encourages children to learn the meaning and importance of health messages on their own. Children will then be most likely to retain and communicate information throughout the family, to neighbors, and to the general community. No blueprint exists, however, on which program planners may base the design of new programs. Programs should instead be adapted by those living within the community and culture to fit local needs and circumstances. Nonetheless, the Aga Khan Foundation supported the study of 7 highly different Child-to-Child projects over 3 years in India to obtain some sense of which program elements are successful and potentially useful in other settings. The study revealed that all of the programs helped increase the health knowledge of children and teachers. Little information was obtained on the extent to which information was diffused by children within the community. Overall, the study produced the following results: planners should consider using Child-to-Child projects in schools; teacher training should be made a priority; administrative support should be provided; entire staffs should be made to feel involved in the decision making process; obstacles to changing teaching methods should not be underestimated; teaching materials should be locally made; projects should be integrated into official curricula; program topics should be relevant to local realities; respected authorities should be called upon to reinforce the validity

    Full Text Available Compared to a decade ago, nearly three times as many drugs for rare diseases are slated for development. This article addresses the market access issues associated with orphan drug status in Europe and the United States in contrast to the legislation in five Latin American (LA countries that have made strides in this regard--Mexico, Brazil, Colombia, Chile and Argentina. Based on the success of orphan drug legislation in the EU and US, LA countries should strive to adopt similar strategies with regard to rare diseases and drug development. With the implementation of new targeted regulations, reimbursement strategies, and drug approvals, accessibility to treatment will be improved for people afflicted with rare diseases in these developing countries.

    Community-based care is receiving increasing global attention as a way to support children who are orphaned or vulnerable due to the HIV/AIDS pandemic. Using both qualitative and quantitative methodology, this study assesses community-based responses to the well-being of orphans and vulnerable children (OVC) and compares these responses with the actual mental health of OVC in order to evaluate the South African government's approach of funding community-based organisations (CBOs) that support and care for OVC. The study results show that the activities of CBOs mainly extend government services and address poverty. Although this should not be seen as insignificant, the paper argues that CBOs give very little attention to the mental health of OVC.

  12. Toward finding gravitational-wave signals from progenitors of short hard gamma-ray bursts and orphaned afterglows

    2013-01-01

    With multiple observatories and missions being planned for detecting orphaned afterglows associated with gamma-ray bursts (GRBs) we emphasize the importance of developing data analysis strategies for searching their possible counterpart signals in the data of gravitational wave (GW) detectors in the advanced detector era. This is especially attractive since short hard gamma-ray bursts (SGRBs) may have compact binary coalescences involving neutron stars (CBCNSs) as their progenitors, which emit gravitational waves. Joint electromagnetic (EM) and GW observations of these objects will enrich our understanding of their beaming, energetics, galactic environment, and shed light on a host of other outstanding questions related to them. Here we recognize some of the astrophysical factors that determine what fraction of CBCNS sources can generate orphaned afterglows. Pipelines already exist that target the sky-position and time of occurrence of SGRBs, known from EM observations, to search for their counterparts in GW ...

    Structural analysis of nuclear receptor subfamily V orphan nuclear receptors suggests that ligand-independent mechanisms must regulate this subclass of receptors. Here, we report that steroidogenic factor 1 (SF-1) and liver receptor homolog 1 are repressed via posttranslational SUMO modification at conserved lysines within the hinge domain. Indeed, mutating these lysines or adding the SUMO isopeptidase SENP1 dramatically increased both native and Gal4-chimera receptor activities. The mechanis...

  5. Strengthening control over radioactive sources in authorized use and regaining control over orphan sources. National strategies

    International Nuclear Information System (INIS)

    The objective of this report is to provide practical guidance to States on the development of a national strategy for improving control over radioactive sources, particularly dangerous sources (Categories 1-3). Part of this process involves the determination of the magnitude of the potential problem with orphan and vulnerable sources and indeed, whether or not a national strategy is needed. The ultimate objective is that States will use this report to develop and then implement a plan of action that will result in all significant sources being managed in a safe and secure manner. This report attempts to provide both the background knowledge and the methodology necessary for an individual or small team of responsible persons to develop a national strategy for improving control over all radioactive sources, but especially orphan and vulnerable sources. The background knowledge given in Chapter 3 is an update of the information on practices that was given in IAEA-TECDOC-804, which focused on spent radioactive sources. After some introductory material, this report provides both the factual information and the general steps needed to develop and implement a national strategy. Part I contains background information for those who are not already familiar with the subject including the need for national strategies, the generic causes of loss of control of sources, with specific examples and the common applications of radioactive sources. Part II details the actual process for the development and implementation of a national strategy, which includes assessing the problem by first gathering specific and national information, determining the nature and magnitude of the problem, developing the national strategy by evaluating, and prioritizing possible solutions, implementing the strategy subsequent to a high level decision; and evaluating the effectiveness of the plan and making changes as a result until the desired objective is achieved.

    IODP Site U1302-U1303, on the SE flank of Orphan Knoll (Labrador Sea), has a record of detrital layers that extends through most of the Brunhes Chron. The age model is built by tandem matching of relative paleointensity (RPI) and oxygen isotope data (δ18O) from Neogloboquadrina pachyderma (sin.) to reference records, indicating a mean Brunhes sedimentation rate of 14 cm/kyr. Sedimentation back to marine isotope stage (MIS) 18 is characterized by detrital layers that are detected by higher than background gamma-ray attenuation (GRA) density, peaks in X-ray fluorescence (XRF) indicators for detrital carbonate (Ca/Sr) and detrital silicate (Si/Sr), an ice-rafted debris (IRD) proxy (>106 μm), magnetic susceptibility, and magnetic grain-size peaks. The age model enables correlation of Site U1302/03 to IODP Site U1308 (re-drill of DSDP Site 609) in the heart of the central Atlantic IRD belt where an age model and a similar set of detrital-layer proxies have already been derived. Ages of Heinrich layers H1, H2, H4, H5 and H6 are within ~2 kyr at the two sites (H0, H3 and H5a are not observed at Site U1308), and agree with previous work at Orphan Knoll within ~3 kyr. At Site U1308, Brunhes detrital layers are restricted to peak glacials and glacial terminations back to MIS16, however, these same proxies at Site U1302/03 indicate detrital layers distributed throughout the record in both glacial and most interglacial stages. At Site U1302/03, we distinguish Heinrich-type layers in glacial stages, which are associated with IRD (some of which have near-synchronous analogues at Site U1308), from detrital layers within interglacial stages manifested by multiple detrital layer proxies (including Ca/Sr) but usually not associated with IRD, that may be attributed to a distinct depositional process, namely drainage and debris-flow events funneled down the nearby NAMOC (North Atlantic Mid-Ocean Channel).

  8. Mining's toxic orphans : a plan for action on federal contaminated and unsafe mine sites

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2000-01-11

    Orphaned mines are a significant liability for the federal government and taxpayers. There are thousands of contaminated sites which are under federal jurisdiction which have been described as orphan sites where there is an abandoned mine for which the organization responsible for the contamination cannot be found or is financially unable to carry out necessary remedial measures within a satisfactory time frame. Several of these sites present immediate safety hazards and health concerns for nearby communities. This paper was prepared in an effort to make recommendations to the federal government about dealing with this responsibility. Section 1 discussed the current state of knowledge regarding the numbers, distribution and dangers of orphaned sites in Canada. Section 2 assessed the extent of federal responsibility for mine clean-up in Canada which is projected at well more than $1 billion. More research is needed to better estimate the financial extent of federal responsibility. The final section includes recommendations for a federal action plan to protect the public interest from contaminated mine sites. It was recommended that the federal action plan should include a national inventory of abandoned mine sites along with a physical and chemical assessment to determine the contamination associated with the site. Actual and potential safety hazards should also be assessed. In addition, an efficient plan should be developed to choose priority sites for clean-up and a funding mechanism should be included based on polluter-pays principles. 60 refs., 1 tab.

    Orphan nuclear receptors are potential therapeutic targets. The Orphan Nuclear Receptor Ligand Binding Database (ONRLDB) is an interactive, comprehensive and manually curated database of small molecule ligands targeting orphan nuclear receptors. Currently, ONRLDB consists of ∼11,000 ligands, of which ∼6500 are unique. All entries include information for the ligand, such as EC50 and IC50, number of aromatic rings and rotatable bonds, XlogP, hydrogen donor and acceptor count, molecular weight (MW) and structure. ONRLDB is a cross-platform database, where either the cognate small molecule modulators of a receptor or the cognate receptors to a ligand can be searched. The database can be searched using three methods: text search, advanced search or similarity search. Substructure search, cataloguing tools, and clustering tools can be used to perform advanced analysis of the ligand based on chemical similarity fingerprints, hierarchical clustering, binning partition and multidimensional scaling. These tools, together with the Tree function provided, deliver an interactive platform and a comprehensive resource for identification of common and unique scaffolds. As demonstrated, ONRLDB is designed to allow selection of ligands based on various properties and for designing novel ligands or to improve the existing ones. Database URL: http://www.onrldb.org/.

  15. An orphan chemotaxis sensor regulates virulence and antibiotic tolerance in the human pathogen Pseudomonas aeruginosa.

    Directory of Open Access Journals (Sweden)

    Heather Pearl McLaughlin

    Full Text Available The synthesis of virulence factors by pathogenic bacteria is highly regulated and occurs in response to diverse environmental cues. An array of two component systems (TCSs serves to link perception of different cues to specific changes in gene expression and/or bacterial behaviour. Those TCSs that regulate functions associated with virulence represent attractive targets for interference in anti-infective strategies for disease control. We have previously identified PA2572 as a putative response regulator required for full virulence of Pseudomonas aeruginosa, the opportunistic human pathogen, to Galleria mellonella (Wax moth larvae. Here we have investigated the involvement of candidate sensors for signal transduction involving PA2572. Mutation of PA2573, encoding a probable methyl-accepting chemotaxis protein, gave rise to alterations in motility, virulence, and antibiotic resistance, functions which are also controlled by PA2572. Comparative transcriptome profiling of mutants revealed that PA2572 and PA2573 regulate expression of a common set of 49 genes that are involved in a range of biological functions including virulence and antibiotic resistance. Bacterial two-hybrid analysis indicated a REC-dependent interaction between PA2572 and PA2573 proteins. Finally expression of PA2572 in the PA2573 mutant background restored virulence to G. mellonella towards wild-type levels. The findings indicate a role for the orphan chemotaxis sensor PA2573 in the regulation of virulence and antibiotic tolerance in P. aeruginosa and indicate that these effects are exerted in part through signal transduction involving PA2572.

    Nuclear orphan receptor TLX is an essential regulator of the growth of neural stem cells. However, its exact function in pancreatic islet cells is still unknown. In the present study, gene expression profiling analysis revealed that overexpression of TLX in beta cell line MIN6 causes suppression of 176 genes and upregulation of 49 genes, including a cadre of cell cycle, cell proliferation and cell death control genes, such as Btg2, Ddit3 and Gadd45a. We next examined the effects of TLX overexpression on proliferation, apoptosis and insulin secretion in MIN6 cells. Proliferation analysis using EdU assay showed that overexpression of TLX increased percentage of EdU-positive cells. Cell cycle and apoptosis analysis revealed that overexpression of TLX in MIN6 cells resulted in higher percentage of cells exiting G1 into S-phase, and a 58.8% decrease of cell apoptosis induced by 0.5 mM palmitate. Moreover, TLX overexpression did not cause impairment of insulin secretion. Together, we conclude that TLX is among factors capable of controlling beta cell proliferation and survival, which may serve as a target for the development of novel therapies for diabetes.

TLX is expressed in the neural stem cells (NSCs of the subventricular zone and the hippocampus subgranular zone, regions with persistent neurogenesis in the adult brain, and functions as an essential regulator of NSCs maintenance and self-renewal. Little is known about the TLX social network of interactors and only few TLX coregulators are described. To identify and characterize novel TLX-binders and possible coregulators, we performed yeast-two-hybrid (Y2H screens of a human adult brain cDNA library using different TLX constructs as baits. Our screens identified multiple clones of Atrophin-1 (ATN1, a previously described TLX interactor. In addition, we identified an interaction with the oncoprotein and zinc finger transcription factor BCL11A (CTIP1/Evi9, a key player in the hematopoietic system and in major blood-related malignancies. This interaction was validated by expression and coimmunoprecipitation in human cells. BCL11A potentiated the transrepressive function of TLX in an in vitro reporter gene assay. Our work suggests that BCL11A is a novel TLX coregulator that might be involved in TLX-dependent gene regulation in the brain.

    We present the first high-resolution spectroscopic study on the Orphan Stream for five stream candidates, observed with the Magellan Inamori Kyocera Echelle (MIKE) spectrograph on the Magellan Clay telescope. The targets were selected from the low-resolution catalog of Casey et al. (2013a): 3 high-probability members, 1 medium and 1 low-probability stream candidate were observed. Our analysis indicates the low and medium-probability target are metal-rich field stars. The remaining three high-probability targets range ~1 dex in metallicity, and are chemically distinct compared to the other 2 targets and all standard stars: low [alpha/Fe] abundances are observed, and lower limits are ascertained for [Ba/Y], which sit well above the Milky Way trend. These chemical signatures demonstrate that the undiscovered parent system is unequivocally a dwarf spheroidal galaxy, consistent with dynamical constraints inferred from the stream width and arc. As such, we firmly exclude the proposed association between NGC 2419 an...

  19. Localization of orphan receptor TR3 mRNA in early developmental follicles in rat

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    By in situ hybridization, the localization of orphan receptor TR3 mRNA has been observed in early developmental follicles. TR3 mRNA is first expressed in the ovarian interstitial cells on day 2 after birth, and then in granulosa cells (GC) in primary follicles on day 4. The expression level of TR3 mRNA in GC increases following the follicular development. Its higher expression can be observed in the outer layer of GC and inner layer of theca cells (TC) on day 6, where the cells present active proliferation and differentiation. The expression of TR3 is in an increasing manner until the large antral follicles on day 30. The mRNA is only expressed in the healthy, but not atretic follicles in adult rat ovaries. Injection of epidermal growth factor (EGF) has dramatically enhanced its expression in the early stage of developmental follicles. It is therefore suggested that TR3 may play a role in regulating growth and differentiation of ovarian somatic cells in the early stage, and its expression is regulated by EGF.

  20. Tie1: an orphan receptor provides context for angiopoietin-2/Tie2 signaling.

    Mueller, Sarah B; Kontos, Christopher D

    2016-09-01

    Angiopoietin-1/Tie2 (ANG1/Tie2) signaling is well documented as regulating angiogenesis and vessel maturation. This pathway is complicated by involvement of the orphan receptor Tie1, which has been implicated as both a positive and negative regulator of ANG1/Tie2 signaling, and ANG2, which can serve as both a Tie2 agonist and antagonist, depending on the context. Two papers in this issue of the JCI provide new insight into this complicated pathway. Korhonen et al. reveal that Tie1 acts to modulate the effects of ANG1 and ANG2 on Tie2 in vitro and in vivo. Kim et al. demonstrate that ANG2 acts as a Tie2 agonist in non-pathological conditions, whereas in the setting of inflammation, ANG2 functions as a Tie2 antagonist and promotes vascular dysfunction. Both studies indicate that inflammation promotes cleavage of the ectodomain of Tie1 and that this cleavage event corresponds with the switch of ANG2 from a Tie2 agonist to an antagonist. The results of these studies lay the groundwork for future strategies to therapeutically exploit this pathway in diseases characterized by adverse vascular remodeling and increased permeability.

    The first one started in 2012 July 16 (MJD 56124) and the second one in 2013 April 9 (MJD 56391). The multiwavelength data analysis shows that the $\\gamma$-ray flare observed in 2012 was not detected in the hard-X ray bands. This result is usually interpreted as an "orphan" flare. In 2013, the analysis of the multiwavelength light curves shows that there are two very bright states detected in the optical R-band. The first one in 2013 April 9 (R =11.74 $\\pm$ 0.04) and the second one in May 12 (R =11.62 $\\pm$ 0.04). Also, high activity states were detected in the soft and hard X-rays. A discrete correlation function analysis of this last flare shows a strong correlation between the GeV $\\gamma$-rays and the optical/hard-X ray emission. These results are discussed in terms of the more adequate standard scenarios that could explain the multiwavelength variations displayed by this blazar.

    Full Text Available Background: Treatments for adolescents affected by long-term loss in low- and middle-income countries are lacking. As school-based interventions are cost-efficient and easy to disseminate, an evaluation of this treatment setting for adolescents is worthwhile. Objective: Examining the effect of a school-based unstructured emotional writing intervention (sensu Pennebaker, group 1 about the loss of a parent to reduce adaptation problems to loss, compared to writing about a hobby (group 2, and non-writing (group 3. Method: We randomly assigned 14–18-year-old Rwandan orphans to one of the three conditions (n=23 per condition. Before and after the intervention, subjects completed the Prolonged Grief Questionnaire for Adolescents and the Mini International Neuropsychiatric Interview for Children and Adolescents, Part A, on depression as self-report measures of long-term effects of early parental loss. Results: Repeated measures analyses of variance showed no differential effect for any of the three conditions but revealed a significant effect of time at posttest regarding grief severity. Reduction of grief symptoms was significantly higher in subjects with elevated grief. Depressive symptoms showed no significant change from pre- to posttest in the emotional writing condition, whereas they significantly decreased in the control condition. Conclusions: Results imply that unstructured, brief emotional writing might not be indicated in adolescents affected by early parental loss who show severe and long-term distress; a more structured approach seems recommendable.

    Orphan diseases are not a common challenge in the everyday practice of the rheumatologist. Despite their extremely rare occurrence one of the patients under our care developed one of them – neuronal ceroid lipofuscinosis, the most frequent neurodegenerative disease observed in the paediatric population. We report a case of 2-year-old girl diagnosed with oligoarticular form of juvenile idiopathic arthritis treated in our Department with steroids and methotrexate and staying in the stage of disease remission. During routine checkups at Outpatient Clinic we observed progressive deterioration of girls neurological condition resulting in ataxia, gait disturbances with no rheumatological cause behind and speech impairment. The appearance of the symptoms was accompanied by frequent episodes of epileptic seizures, with little clinical improvement on combined antiepileptic treatment. Magnetic resonance imaging that we performed showed a picture highly suggestive of neuronal ceroid lipofuscinosis – atrophy of the patients cerebrum and cerebellum. Genetic testing conducted resulted in the diagnosis of late infantile neuronal ceroid lipofuscinosis (LINCL). PMID:27504025

    Orphans and separated children (OSC) are a vulnerable population whose numbers are increasing, particularly in sub-Saharan Africa and Asia. Over 153 million children worldwide have lost one or both parents, including 17 million orphaned by AIDS, and millions more have been separated from their parents. As younger orphans enter adolescence, their sexual health and HIV-related risk behaviors become key considerations for their overall health. Importantly, their high prevalence of exposure to potentially traumatic events (PTEs) may put OSC at additional risk for adverse sexual health outcomes. The Positive Outcomes for Orphans study followed OSC randomly sampled from institution-based care and from family-based care, as well as a convenience sample of non-OSC, at six sites in five low-and middle-income countries. This analysis focused on the 90-month follow-up, during which adolescents 16 and older were assessed for sexual health, including age at sexual debut, past-year sex, past-year condom use, and perceptions of condom use. We specifically examined the relationship between PTEs and sexual health outcomes. Of the 1258 OSC and 138 non-OSC assessed, 11% reported ever having sex. Approximately 6% of participants reported recent sex and 5% reported having recent unprotected sex. However, 70% of those who had recent sex reported that they did not use a condom every time, and perceptions of condom use tended to be unfavorable for protection against sexual risk behavior. Nearly all (90%) of participants reported experiencing at least one lifetime PTE. For those who experienced "any" PTE, we found increased prevalence of recent sex (PR = 1.39 [0.47, 4.07]) and of recent unprotected sex (PR = 3.47 [0.60, 19.91]). This study highlights the need for caregivers, program managers, and policymakers to promote condom use for sexually active OSC and identify interventions for trauma support services. Orphans living in family-based care may also be particularly vulnerable

  20. The battered child syndrome

    International Nuclear Information System (INIS)

    The recognition of a battered child represents a challenge for all groups of adults dealing with children. Radiology plays a special role in this setting. By detection typical injuries, imaging is able to confirm the suspicion of a battered child. Recognition of those injuries on films, taken for other reasons, gives the caretaker an important hint, thus maybe preventing a fatal outcome for the child. One of the most important injury types is represented by the so called ''shakin baby syndrome''. The infant is held by the thorax and shaken. Thus causing a repetitive acceleration-deceleration trauma, which leads to the typical paravertebral rib fractures, intracranial bleeding and eye injuries. After shaking the child is thrown away, with subsequent injuries. The aim of this article is the presentation of an overview regarding the radiology of the battered child. Typical examples will be shown. (orig.)

    Child prostitution is an old, global and complex phenomenon, which deprives children of their childhood, human rights and dignity. Child prostitution can be seen as the commercial sexual exploitation of children involving an element of forced labour, and thus can be considered as a contemporary form of slavery. Globally, child prostitution is reported to be a common problem in Central and South America and Asia. Of all the south-east Asian nations, the problem is most prolific in Thailand. In Thailand, there appears to be a long history of child prostitution, and this article explores the factors that underpin the Thai child sex industry and the lessons and implications that can be drawn for health care and nursing around the world.

    Focusing on the benefits of patients with rare disease the authors analysed the aspects of orphan medicines financed in the frame of the Hungarian social insurance system in 2012 in order to make the consumption more rational, transparent and predictable. Most of the orphan drugs were financed in the frame of compassionate use by the reimbursement system. Consequently, a great deal of crucial problems occurred in relation to the unconventional subsidized method, especially in the case of the highest cost enzyme replacement therapies. On the base of the findings, proposals of the authors are presented for access to orphan drugs, fitting to the specific professional, economical and ethical aspects of this unique field of the health care system. The primary goal is to provide a suitable subsidized method for the treatment of rare disease patients with unmet medical needs. The financial modification of orphans became indispensible in Hungary. Professionals from numerous fields dealing with rare disease patients' care expressed agreement on the issue. Transforming the orphan medicines' financial structure has been initiated according to internationally shared principles.

    Pulmonary surfactant levels within the alveoli are tightly regulated to maintain lung volumes and promote efficient gas exchange across the air/blood barrier. Quantitative and qualitative abnormalities in surfactant are associated with severe lung diseases in children and adults. Although the cellular and molecular mechanisms that control surfactant metabolism have been studied intensively, the critical molecular pathways that sense and regulate endogenous surfactant levels within the alveolus have not been identified and constitute a fundamental knowledge gap in the field. In this study, we demonstrate that expression of an orphan G protein-coupled receptor, GPR116, in the murine lung is developmentally regulated, reaching maximal levels 1 day after birth, and is highly expressed on the apical surface of alveolar type I and type II epithelial cells. To define the physiological role of GPR116 in vivo, mice with a targeted mutation of the Gpr116 locus, Gpr116(Δexon17), were generated. Gpr116(Δexon17) mice developed a profound accumulation of alveolar surfactant phospholipids at 4 weeks of age (12-fold) that was further increased at 20 weeks of age (30-fold). Surfactant accumulation in Gpr116(Δexon17) mice was associated with increased saturated phosphatidylcholine synthesis at 4 weeks and the presence of enlarged, lipid-laden macrophages, neutrophilia, and alveolar destruction at 20 weeks. mRNA microarray analyses indicated that P2RY2, a purinergic receptor known to mediate surfactant secretion, was induced in Gpr116(Δexon17) type II cells. Collectively, these data support the concept that GPR116 functions as a molecular sensor of alveolar surfactant lipid pool sizes by regulating surfactant secretion. PMID:23590306

    Hereditary haemorrhagic telangiectasia (HHT), or Rendu-Osler-Weber syndrome, is a dominant genetic vascular disorder. In HHT, blood vessels are weak and prone to bleeding, leading to epistaxis and anaemia, severely affecting patients' quality of life. Development of vascular malformations in HHT patients is originated mainly by mutations in ACVRL1/ALK1 (activin receptor-like kinase type I) or Endoglin (ENG) genes. These genes encode proteins of the TGF-β signalling pathway in endothelial cells, controlling angiogenesis. Haploinsufficiency of these proteins is the basis of HHT pathogenicity. It was our objective to study the efficiency of Bazedoxifene, a selective estrogen receptor modulator (SERM) in HHT, looking for a decrease in epistaxis, and understanding the underlying molecular mechanism. Plasma samples of five HHT patients were collected before, and after 1 and 3 months of Bazedoxifene treatment. ENG and ALK1 expression in activated mononuclear cells derived from blood, as well as VEGF plasma levels, were measured. Quantification of Endoglin and ALK1 mRNA was done in endothelial cells derived from HHT and healthy donors, after in vitro treatment with Bazedoxifene. Angiogenesis was also measured by tubulogenesis and wound healing assays. Upon Bazedoxifene treatment, haemoglobin levels of HHT patients increased and the quantity and frequency of epistaxis decreased. Bazedoxifene increased Endoglin and ALK1 mRNA levels, in cells derived from blood samples and in cultured endothelial cells, promoting tube formation. In conclusion, Bazedoxifene seems to decrease bleeding in HHT by partial compensation of haploinsufficiency. The results shown here are the basis of a new orphan drug designation for HHT by the European Medicine Agency (EMA). PMID:26818701

  10. Plant insecticide L-canavanine repels Drosophila via the insect orphan GPCR DmX.

    Full Text Available For all animals, the taste sense is crucial to detect and avoid ingesting toxic molecules. Many toxins are synthesized by plants as a defense mechanism against insect predation. One example of such a natural toxic molecule is L-canavanine, a nonprotein amino acid found in the seeds of many legumes. Whether and how insects are informed that some plants contain L-canavanine remains to be elucidated. In insects, the taste sense relies on gustatory receptors forming the gustatory receptor (Gr family. Gr proteins display highly divergent sequences, suggesting that they could cover the entire range of tastants. However, one cannot exclude the possibility of evolutionarily independent taste receptors. Here, we show that L-canavanine is not only toxic, but is also a repellent for Drosophila. Using a pharmacogenetic approach, we find that flies sense food containing this poison by the DmX receptor. DmXR is an insect orphan G-protein-coupled receptor that has partially diverged in its ligand binding pocket from the metabotropic glutamate receptor family. Blockade of DmXR function with an antagonist lowers the repulsive effect of L-canavanine. In addition, disruption of the DmXR encoding gene, called mangetout (mtt, suppresses the L-canavanine repellent effect. To avoid the ingestion of L-canavanine, DmXR expression is required in bitter-sensitive gustatory receptor neurons, where it triggers the premature retraction of the proboscis, thus leading to the end of food searching. These findings show that the DmX receptor, which does not belong to the Gr family, fulfills a gustatory function necessary to avoid eating a natural toxin.

    Intestinal parasitic infections can negatively impact growth and nutrition in children. The infections can induce oxidative stress, resulting in a variety of illnesses. We measured antioxidant enzyme levels in orphan children infected with intestinal parasites to investigate the influence of nutritional status on antioxidant enzymes. This cross sectional study was conducted at an orphanage in Thailand. Stool samples were obtained from each subject and examined for intestinal parasites. Anthropometric measurements, complete blood count and biochemical parameters, including serum superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels, were obtained from studied subjects. One hundred twenty-eight children were included in the study. Intestinal parasites were found on microscopic examination of the stools in 36.7% (47/128); 18% (23/128) had a mixed parasite infection. Intestinal protozoa were found in 34.4% of subjects and intestinal helminthes were found in 2.3%. The median GPx level in children infected with intestinal parasites (2.3 ng/ml) was significantly lower than in non-infected children (7.7 ng/ml) (p < 0.05). However, there was no significant difference in SOD levels between the two groups. When comparing GPx levels in children with 1) pathogenic parasites, 2) non-pathogenic parasites and 3) no intestinal parasite infection, GPx levels differed significantly among three groups (2.2 ng/ml, 2.4 ng/ml and 7.7 ng/ml, respectively) (p < 0.05). When separating children by BMI and type of infection, the median SOD level in underweight children infected with pathogenic parasites (107.2 ng/ml) was significantly higher than in underweight children infected with non-pathogenic parasites (68.6 ng/ml) and without intestinal parasite infections (72.2 ng/ml). The present study identified two key findings: low GPx levels in children with intestinal parasitic infections, and the potential impact of malnutrition on some antioxidants. PMID:26466411

  12. Molecular pathways: the role of NR4A orphan nuclear receptors in cancer.

    Nuclear receptors are of integral importance in carcinogenesis. Manipulation of classic ligand-activated nuclear receptors, such as estrogen receptor blockade in breast cancer, is an important established cancer therapy. Orphan nuclear receptors, such as nuclear family 4 subgroup A (NR4A) receptors, have no known natural ligand(s). These elusive receptors are increasingly recognized as molecular switches in cell survival and a molecular link between inflammation and cancer. NR4A receptors act as transcription factors, altering expression of downstream genes in apoptosis (Fas-ligand, TRAIL), proliferation, DNA repair, metabolism, cell migration, inflammation (interleukin-8), and angiogenesis (VEGF). NR4A receptors are modulated by multiple cell-signaling pathways, including protein kinase A\\/CREB, NF-κB, phosphoinositide 3-kinase\\/AKT, c-jun-NH(2)-kinase, Wnt, and mitogen-activated protein kinase pathways. NR4A receptor effects are context and tissue specific, influenced by their levels of expression, posttranslational modification, and interaction with other transcription factors (RXR, PPAR-Υ). The subcellular location of NR4A "nuclear receptors" is also important functionally; novel roles have been described in the cytoplasm where NR4A proteins act both indirectly and directly on the mitochondria to promote apoptosis via Bcl-2. NR4A receptors are implicated in a wide variety of malignancies, including breast, lung, colon, bladder, and prostate cancer; glioblastoma multiforme; sarcoma; and acute and\\/or chronic myeloid leukemia. NR4A receptors modulate response to conventional chemotherapy and represent an exciting frontier for chemotherapeutic intervention, as novel agents targeting NR4A receptors have now been developed. This review provides a concise clinical overview of current knowledge of NR4A signaling in cancer and the potential for therapeutic manipulation.

  13. Comparative Analysis of the Orphan CRISPR2 Locus in 242 Enterococcus faecalis Strains.

    Directory of Open Access Journals (Sweden)

    Karthik Hullahalli

    Full Text Available Clustered, Regularly Interspaced Short Palindromic Repeats and their associated Cas proteins (CRISPR-Cas provide prokaryotes with a mechanism for defense against mobile genetic elements (MGEs. A CRISPR locus is a molecular memory of MGE encounters. It contains an array of short sequences, called spacers, that generally have sequence identity to MGEs. Three different CRISPR loci have been identified among strains of the opportunistic pathogen Enterococcus faecalis. CRISPR1 and CRISPR3 are associated with the cas genes necessary for blocking MGEs, but these loci are present in only a subset of E. faecalis strains. The orphan CRISPR2 lacks cas genes and is ubiquitous in E. faecalis, although its spacer content varies from strain to strain. Because CRISPR2 is a variable locus occurring in all E. faecalis, comparative analysis of CRISPR2 sequences may provide information about the clonality of E. faecalis strains. We examined CRISPR2 sequences from 228 E. faecalis genomes in relationship to subspecies phylogenetic lineages (sequence types; STs determined by multilocus sequence typing (MLST, and to a genome phylogeny generated for a representative 71 genomes. We found that specific CRISPR2 sequences are associated with specific STs and with specific branches on the genome tree. To explore possible applications of CRISPR2 analysis, we evaluated 14 E. faecalis bloodstream isolates using CRISPR2 analysis and MLST. CRISPR2 analysis identified two groups of clonal strains among the 14 isolates, an assessment that was confirmed by MLST. CRISPR2 analysis was also used to accurately predict the ST of a subset of isolates. We conclude that CRISPR2 analysis, while not a replacement for MLST, is an inexpensive method to assess clonality among E. faecalis isolates, and can be used in conjunction with MLST to identify recombination events occurring between STs.

    We present a 500-km long, 2-D P-wave velocity model across the Orphan Basin, offshore NE Newfoundland, Canada, from Flemish Cap to the Bonavista Platform, formed using refraction and wide-angle reflection data from 89 ocean-bottom seismometers. This layered model builds on a recent traveltime tomography result using additional constraints from coincident multichannel seismic reflection and gravity data plus borehole logs from three wells. The model shows (i) post-rift Tertiary (velocities ˜1.7-3.5 km s-1) and (ii) both post-rift and syn-rift, Cretaceous and Jurassic sediments (˜4-5 km s-1), deposited within an eastern and a western sub-basin that are separated by a major basement block. The existence of Jurassic sediments indicates a pre-Cretaceous rifting phase in the eastern sub-basin, and possibly in the western sub-basin. However, there is no evidence that Triassic sediments are widespread across the Orphan Basin. Two upper crustal sublayers and one lower crustal layer are defined by differences in velocities (5.4-6.1, 6.1-6.5 and 6.3-7.1 km s-1, respectively) and vertical velocity gradients (mean = 0.14, 0.10 and 0.05 s-1, respectively). Crustal thinning is asymmetric across the Orphan Basin. Within the eastern sub-basin, continental crust beneath Flemish Cap (˜32 km thick; β ˜ 1.1) thins westward into a 35-km-wide zone of hyperextended crust ( 3.4) beneath an 11-km-deep sedimentary basin. Within the western sub-basin, the Bonavista Platform crust (˜32 km thick) thins eastward into a 116-km-wide zone of hyperextended crust. Two zones of thicker crust (β = 2-3.5) exist within the central section, with muted topography within the eastern part and large basement highs in the western part, separated by the eastward dipping White Sail Fault (WSF). The zone to the east of the WSF displays higher velocities in the lower crust than to the west. This can only be explained by a lateral ductile flow across the zone boundary. By combining the two upper crustal

    Singhi, Pratibha; Saini, Arushi Gahlot; Malhi, Prabhjot

    2013-11-01

    Child maltreatment is a global problem but is more difficult to assess and manage in developing countries such as India where one-fifth of the world's total child population resides. Certain forms of maltreatment such as feticide, infanticide, abandonment, child labour, street-begging, corporal punishment and battered babies are particularly prevalent in India. Most physicians still need to be sensitized in order to suspect child abuse on the basis of unexplained trauma, multiple fractures, parental conflict and other corroborative evidence. This article summarizes the various aspects of this major problem in resource-poor settings in the hope that it will assist in the planning of services addressing child physical and sexual abuse and neglect in India and in other developing countries. A culture of non-violence towards children needs to be built into communities in order to provide an environment conducive to the overall development of the child. Rehabilitation of abused children and their families requires a multi-disciplinary service including paediatricians, child psychologists and social workers, and the training of police forces in how to tackle the problem.

  19. Could a plasma in quasi-thermal equilibrium be associated to the "orphan" TeV flares?

    Science.gov (United States)

    Fraija, N.

    2015-12-01

    TeV γ-ray detections in flaring states without activity in X-rays from blazars have attracted much attention due to the irregularity of these "orphan" flares. Although the synchrotron self-Compton model has been very successful in explaining the spectral energy distribution and spectral variability of these sources, it has not been able to describe these atypical flaring events. On the other hand, an electron-positron pair plasma at the base of the AGN jet was proposed as the mechanism of bulk acceleration of relativistic outflows. This plasma in quasi-thermal equilibrium called Wein fireball emits radiation at MeV-peak energies serving as target of accelerated protons. In this work we describe the "orphan" TeV flares presented in blazars 1ES 1959+650 and Mrk 421 assuming geometrical considerations in the jet and evoking the interactions of Fermi-accelerated protons and MeV-peak target photons coming from the Wein fireball. After describing successfully these "orphan" TeV flares, we correlate the TeV γ-ray, neutrino and UHECR fluxes through pγ interactions and calculate the number of high-energy neutrinos and UHECRs expected in IceCube/AMANDA and TA experiment, respectively. In addition, thermal MeV neutrinos produced mainly through electron-positron annihilation at the Wein fireball will be able to propagate through it. By considering two- (solar, atmospheric and accelerator parameters) and three-neutrino mixing, we study the resonant oscillations and estimate the neutrino flavor ratios as well as the number of thermal neutrinos expected on Earth.

    2004-09-01

    An examination of the economic consequences for older-age parents of losing an adult child to AIDS in Thailand based on quantitative data derived from a key informant study and a direct interview survey with parents yielded the following main findings: (1) parents frequently paid for their children's care and treatment, but government health insurance and to a lesser extent welfare measures helped alleviate these expenses; (2) parental caregiving often disrupted economic activity, although the resulting opportunity costs were limited by the typically short duration of caregiving; (3) parents commonly paid for funeral costs but benefited from funeral society memberships and customary contributions from those attending; (4) only a minority of parents supported AIDS orphans although orphaned grandchildren often ended up with their grandparents; (5) most deceased children had contributed financially to the parental household but only a minority were main providers. Poorer parents, however, were most likely to lose a main provider and experience severe financial hardship; and (6) although poorer parents spent much less on expenses related to the illness and death of their children, they were much more likely than better-off parents to be seriously burdened by these expenses. Programs are needed to address the plight of AIDS parents but should target those who are most susceptible to resulting economic hardship. PMID:15186899

  6. The CanOE strategy: integrating genomic and metabolic contexts across multiple prokaryote genomes to find candidate genes for orphan enzymes.

    2012-05-01

    Full Text Available Of all biochemically characterized metabolic reactions formalized by the IUBMB, over one out of four have yet to be associated with a nucleic or protein sequence, i.e. are sequence-orphan enzymatic activities. Few bioinformatics annotation tools are able to propose candidate genes for such activities by exploiting context-dependent rather than sequence-dependent data, and none are readily accessible and propose result integration across multiple genomes. Here, we present CanOE (Candidate genes for Orphan Enzymes, a four-step bioinformatics strategy that proposes ranked candidate genes for sequence-orphan enzymatic activities (or orphan enzymes for short. The first step locates "genomic metabolons", i.e. groups of co-localized genes coding proteins catalyzing reactions linked by shared metabolites, in one genome at a time. These metabolons can be particularly helpful for aiding bioanalysts to visualize relevant metabolic data. In the second step, they are used to generate candidate associations between un-annotated genes and gene-less reactions. The third step integrates these gene-reaction associations over several genomes using gene families, and summarizes the strength of family-reaction associations by several scores. In the final step, these scores are used to rank members of gene families which are proposed for metabolic reactions. These associations are of particular interest when the metabolic reaction is a sequence-orphan enzymatic activity. Our strategy found over 60,000 genomic metabolons in more than 1,000 prokaryote organisms from the MicroScope platform, generating candidate genes for many metabolic reactions, of which more than 70 distinct orphan reactions. A computational validation of the approach is discussed. Finally, we present a case study on the anaerobic allantoin degradation pathway in Escherichia coli K-12.

    2016-01-01

    ABSTRACT Within Kenya, an estimated quarter of a million children live on the streets, and 1.8 million children are orphaned. In this study, we analyze how HIV contributes to the phenomenon of child-street migration. We interviewed a random community sample of caregiving women (n = 1974) in Meru County, Kenya, using a structured questionnaire in summer 2015. Items included reported HIV prevalence of respondent and her partner, social support, overall health, school enrollment of biologically related children and whether the respondent has a child currently living on the streets. Controlling for alcohol use, education, wealth, age and household size, we found a positive-graded association between the number of partners living with HIV and the probability that a child lives on the street. There was little difference in the odds of a child living on the street between maternally affected and paternally affected households. Lower maternal social support, overall health and school enrollment of biologically related children mediated 14% of the association between HIV-affected households and reporting child-street migration. Street-migration of children is strongly associated with household HIV, but the small percentage of mediated effect presents a greater need to focus on interactions between household and community factors in the context of HIV. Programs and policies responding to these findings will involve targeting parents and children in HIV-affected households, and coordinate care between clinical providers, social service providers and schools.

Music, as a therapy was shown to have positive effects in child care, such as in premature infants, children in emergency care, children receiving surgery, children in oncology departments and handicapped children. The aim of this review was to study the therapeutic effects of music in child care at hospital. The method οf this study included bibliography research from both the review and the research internatio nal literature, which was referred to the therapeutic effects of music in Children's Hospital. Results: Most studies focus on the beneficial effects of music to child. The results of the study showed that music is widely used to enhance well‐being and appears to exert direct effects to child, which are mainly related to physiology and psychology, including changes in the vital signs, reductions in anxiety and pain, distraction of attention from unpleasant sensations and better communication with the environment at hospital. Furthermore, music exerts indirect effects to child since is able to cause positive modifications in nurses' behaviour and conduces to better performance in their duties. Conclusions: Music consists a low-cost "therapeutic instrument" for nurses to apply to child-patient and is found to be effective in producing positive outcomes. The nurses' knowledge of music therapy need to be improved and the therapeutic impact of music must be a result from systematic professional application.

    Full Text Available Carlton Dampier1,2 1Emory University School of Medicine, Emory University, 2AFLAC Cancer and Blood Disorders Center, Children's Healthcare of Atlanta, Atlanta, GA, USA Abstract: While an orphan disease in the USA, sickle cell disease (SCD, a group of genetic disorders of hemoglobin structure and function, is a major public health problem in much of the rest of the world, particularly sub-Saharan Africa. The pathophysiology of SCD stems from the formation of sickle hemoglobin polymers that deform the erythrocyte into a characteristic sickle shape, the rapidity of which is regulated by its intracellular hemoglobin concentration. Subsequent vaso-occlusion is dependent on adhesion of sickled erythrocytes, and perhaps other cellular elements, including leucocytes and platelets, to abnormal vascular endothelium using a number of receptor–ligand pairs. This propensity for vaso-occlusion may be enhanced by altered vascular tone from excessive amounts of vaso-constrictive factors or diminished amounts of vasodilatory factors. Acute pain is the hallmark symptom caused by sickle polymer formation and subsequent vaso-occlusion, and is represented in the endpoints of most previous and current clinical trial designs. Numerous failures of prior investigational agents have frustrated clinicians and patients alike. Hydroxyurea is currently the only US Food and Drug Administration-approved drug for SCD and reduces the frequency of vaso-occlusive complications in many individuals. A considerable therapeutic need remains as hydroxyurea usage is currently not approved for all types of SCD, is not always clinically effective, and requires frequent monitoring. Recent improvements in our understanding of SCD pathophysiology have generated many new therapeutic targets and associated investigational agents. For example, a number of more specific fetal hemoglobin inducers and several therapies to reduce sickle polymer formation are being tested in preclinical and early

    In our previous studies, the TR4 orphan nuclear receptor (TR4) has been demonstrated to suppress retinoic acid (RA)-induced transactivation via a negative feedback control mechanism and in situ analysis showed that TR4 is extensively expressed in mouse brain, especially in regions where the cells are proliferating. To further study the potential roles of TR4 during cell differentiation, a tetracycline-inducible system with anti-sense TR4 in teratocarcinoma P19 cell lines was generated to analyze the retinoic acid-induced differentiation of these cells. The results indicated that the expression of TR4 reduced by doxycycline anti-sense TR4 would alter the retinoic acid-induced differentiation pathway that results in the changes of cell morphology and cell cycle profile. Unexpectedly, our data further indicated that the RA-induced apoptosis, judging by DNA fragmentation, could also be altered by the induction of anti-sense TR4. Together, these findings provide the first in vivo evidence that an orphan nuclear receptor, such as TR4, may play major roles in the RA-mediated apoptosis or differentiation in P19 cells

  11. Child life services.

    Science.gov (United States)

    2014-05-01

    Child life programs are an important component of pediatric hospital-based care to address the psychosocial concerns that accompany hospitalization and other health care experiences. Child life specialists focus on the optimal development and well-being of infants, children, adolescents, and young adults while promoting coping skills and minimizing the adverse effects of hospitalization, health care, and/or other potentially stressful experiences. Using therapeutic play, expressive modalities, and psychological preparation as primary tools, in collaboration with the entire health care team and family, child life interventions facilitate coping and adjustment at times and under circumstances that might otherwise prove overwhelming for the child. Play and developmentally appropriate communication are used to: (1) promote optimal development; (2) educate children and families about health conditions; (3) prepare children and families for medical events or procedures; (4) plan and rehearse useful coping and pain management strategies; (5) help children work through feelings about past or impending experiences; and (6) establish therapeutic relationships with patients, siblings, and parents to support family involvement in each child's care.

    艾滋病孤儿是社会中的弱势群体,他们不仅承担着生活重负,而且还承受着无形的心理压力.国内外多项研究显示,艾滋病孤儿存在孤独、自卑、自我封闭和偏激逆反等不良的心理问题,若不能给予足够的重视和有效的干预,该群体势必将成为严重的社会和公共卫生问题.全社会都应加大对艾滋病孤儿的关注,开展更多的心理关怀活动,促进艾滋病孤儿全面健康成长.%AIDS orphans are the most vulnerable groups in society as they bear not only the burden of life but also the intangible psychological stress. Studies have shown that AIDS orphans have solitude, low self-esteem, self-isolation,bias to the society and other psychological problems, which might become a serious social and public health issue if not given enough attention and effective intervention. The whole community, including the government should increase the care of AIDS orphans and do more psychological care activities to promote healthy growth of AIDS orphans.

    Currently in Europe, approximately 30 million people suffer from rare diseases, and a major problem is that many patients do not have access to quality healthcare for their disorders. Moreover, there is also a lack of quality information and a networking system aimed at supporting interaction among patients, clinicians, researchers, pharmaceutical industries, and governmental bodies. The purpose of this article is to inform physicians, public health care professionals, and other health care providers about EuOrphan service, the aim of which is to ensure easier access to quality information on rare diseases and their treatment. A set of web-based services is available at www.euorphan.com where information for target-users on treatments and products available worldwide for rare disease care as well as indications about healthcare centers are provided. Moreover, the service aims at providing consultancies for pharmaceutical companies to ultimately support the European legislation in bringing new drugs of a high ethical standard to the market and to exert a positive impact on the large population of patients suffering from rare diseases in Europe. The services provided by EuOrphan can facilitate concrete networking among patients, patient associations, doctors, and companies and also support the organization of clinical trials. In this perspective, EuOrphan could become a very valuable tool for globalizing the information about the availability of treatment (authorized or under development) of orphan patients.

    Dong XU; Yi-jun HUANG; Yan LI; Wei YIN; Guang-mei YAN

    2009-01-01

    Aim: To investigate a possible regulator gene involved in the cholera toxin-induced differentiation of rat C6 glioma cells. Methods: The global changes in the mRNA expression pattern induced by cholera toxin were analyzed using gene chip microarray. The selected gene was then silenced by RNA interference or overexpressed with an ORF plasmid to determine its necessity in this process. Results: Nur77, a member of the orphan nuclear receptor family (NR4A), was markedly up-regulated during the process of differentiation. Furthermore, RNAi of nur77 attenuated the induction effect of cholera toxin on C6 cells, whereas overexpression of nur77 led to similarly differentiated behavior, including morphologic and biomarker changes, as well as cell cycle arrest. Conclusion: Nur77 participated actively and essentially as an important regulator in the cholera toxin-induced differentiation of C6 cells.

    2015-01-20

    The Gram-positive bacterium Paenibacillus larvae is the causative agent of the fateful honey bee disease American Foulbrood (AFB). Sequence analysis of P. larvae genomic DNA showed the presence of numerous nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) encoding gene clusters, not correlating with secondary metabolite production. As NRPS and PKS derived metabolites are known to exhibit diverse biological activities, their identification is of particular interest for infection and drug research. Here an 11.6kb orphan NRPS gene cluster was directly cloned from the genomic DNA of P. larvae and expressed in Escherichia coli resulting in the production of sevadicin. Isolation of the metabolite was followed by structural characterization, synthesis and bioactivity studies. PMID:25529345

  12. Crystallographic Identification and Functional Characterization of Phospholipids as Ligands for the Orphan Nuclear Receptor Steroidogenic Factor-1

    2010-11-10

    The orphan nuclear receptor steroidogenic factor 1 (SF-1) regulates the differentiation and function of endocrine glands. Although SF-1 is constitutively active in cell-based assays, it is not known whether this transcriptional activity is modulated by ligands. Here, we describe the 1.5 {angstrom} crystal structure of the SF-1 ligand binding domain in complex with an LXXLL motif from a coregulator protein. The structure reveals the presence of a phospholipid ligand in a surprisingly large pocket ({approx}1600 {angstrom}{sup 3}), with the receptor adopting the canonical active conformation. The bound phospholipid is readily exchanged and modulates SF-1 interactions with coactivators. Mutations designed to reduce the size of the SF-1 pocket or to disrupt hydrogen bonds with the phospholipid abolish SF-1/coactivator interactions and significantly reduce SF-1 transcriptional activity. These findings provide evidence that SF-1 is regulated by endogenous ligands and suggest an unexpected relationship between phospholipids and endocrine development and function.

    Tie1 is a mechanistically poorly characterized endothelial cell (EC)-specific orphan receptor. Yet, Tie1 deletion is embryonic lethal and Tie1 has been implicated in critical vascular pathologies, including atherosclerosis and tumor angiogenesis. Here, we show that Tie1 does not function independently but exerts context-dependent effects on the related receptor Tie2. Tie1 was identified as an EC activation marker that is expressed during angiogenesis by a subset of angiogenic tip and remodeling stalk cells and downregulated in the adult quiescent vasculature. Functionally, Tie1 expression by angiogenic EC contributes to shaping the tip cell phenotype by negatively regulating Tie2 surface presentation. In contrast, Tie1 acts in remodeling stalk cells cooperatively to sustain Tie2 signaling. Collectively, our data support an interactive model of Tie1 and Tie2 function, in which dynamically regulated Tie1 versus Tie2 expression determines the net positive or negative effect of Tie1 on Tie2 signaling.

    2013-03-01

    We have previously reported that members of the NR4A family of orphan nuclear receptors can augment insulin's ability to stimulate glucose transport in adipocytes. In the current study, we endeavored to test for an insulin-sensitizing effect in muscle cells and to identify a potential transactivator. Lentiviral constructs were used to engineer both hyperexpression and shRNA silencing of NR4A3 in C2C12 myocytes. The NR4A3 hyper-expression construct led to a significant increase in glucose transport rates in the presence of maximal insulin while the NR4A3 knock-down exhibited a significant reduction in insulin-stimulated glucose transport rates. Consistently, insulin-mediated AKT phosphorylation was increased by NR4A3 hyperexpression and decreased following shRNA NR4A3 suppression. Then, we examined effects of prostaglandin A2 (PGA2) on insulin action and NR4A3 transactivation. PGA2 augmented insulin-stimulated glucose uptake in C2C12 myocytes and AKT phosphorylation after 12-h treatment, without significant effects on basal transport or basal AKT phosphorylation. More importantly, we demonstrated that PGA2 led to a greater improvement in insulin-stimulated glucose rates in NR4A3 overexpressing C2C12 myocytes, when compared with Lac-Z controls stimulated with insulin and PGA2. Moreover, the sensitizing effect of PGA2 was significantly diminished in NR4A3 knockdown myocytes compared to scramble controls. These results show for the first time that: (i) PGA2 augments insulin action in myocytes as manifested by enhanced stimulation of glucose transport and AKT phosphorylation; and (ii) the insulin sensitizing effect is dependent upon the orphan nuclear receptor NR4A3.

Internet is a perfect environment for children, for exploring the world, learning and having fun. However, access to illegal sites that contain violence and sexuality, and contact dangerous people are among the particular risks for children using the internet. It is a known fact that, internet and developing technology make the production and distribution of child pornography cheaper and easier. There has been consensus on the need of creating a plan and increasing the awareness in the community for the fight against child pornography. Because of the increasing internet use and the risk for children mentioned, nurses got new responsibilities. Nurses have to inform society, especially families and children, about safe internet use. In this review, legal regulations about the fight against child pornography on the internet, the reasons that lay the ground for child pornography and their negative effects on children has been addressed.

    2005-04-01

    Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

  12. Paying for the Orphan Drug System: break or bend? Is it time for a new evaluation system for payers in Europe to take account of new rare disease treatments?

    Directory of Open Access Journals (Sweden)

    Hughes-Wilson Wills

    2012-09-01

    Full Text Available Abstract Since its enactment in 2000, the European Orphan Medicinal Products Regulation has allowed the review and approval of approaching 70 treatments for some 55 different conditions in Europe. Success does not come without a price, however. Many of these so-called “orphan drugs” have higher price points than treatments for more common diseases. This has been raising debate as to whether the treatments are worth it, which, in turn risks blocking patient access to treatment. To date, orphan drugs have only accounted for a small percentage of the overall drug budget. It would appear that, with increasing numbers of orphan drugs, governments are concerned about the future budget impact and their cost-effectiveness in comparison with other healthcare interventions. Orphan drugs are under the spotlight, something that is likely to continue as the economic crisis in Europe takes hold and governments respond with austerity measures that include cuts to healthcare expenditures. Formally and informally, governments are looking at how they are going to handle orphan drugs in the future. Collaborative proposals between EU governments to better understand the value of orphan drugs are under consideration. In recent years there has been increasing criticism of behaviours in the orphan drug field, mainly centring on two key perceptions of the system: the high prices of orphan drugs and their inability to meet standard cost-effectiveness thresholds; and the construct of the system itself, which allows companies to gain the benefits that accrue from being badged as an orphan drug. The authors hypothesise that, by examining these criticisms individually, one might be able to turn these different “behaviours” into criteria for the creation of a system to evaluate new orphan drugs coming onto the market. It has been acknowledged that standard methodologies for Health Technology Assessments (HTA will need to be tailored to take into account the

  13. CHILD LABOR DISGRACE

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The Shanxi Province child labor scandal has shocked China to its core. Over 1,000 children were forced into illegal labor by morally bankrupt brick kiln businesses, throwing a depressing shroud over China’s rapid development. Uncovering these tales of abduction, death and the physical and mental abuse endured by these children has been a proud moment for China’s press. Several hundred of the kiln slave children have now been reunited with their families. Kiln owners, contractors and accomplices are being brought to justice or hunted down, some even charged with murder.However, in all this gloom some good has surfaced.Public and government attention is now focused on erasing child labor once and for all and for better protecting workers’ rights, hopefully ridding China of such disgraces in the future.

    BACKGROUND: The importance of the environment on the development of the fetus and infant throughout early life is increasingly recognised. To study such effects, biological samples and accurate data records are required. Based on multiple data collection from a healthy pregnant population......, the Odense Childhood Cohort (OCC) study aims to provide new information about the environmental impact on child health by sequential follow-up to 18 years of age among children born between 2010 and 2012. METHODS: A total of 2874 of 6707 pregnancies (43%) were recruited between January 2010 and December 2012...... provides material for in-depth analysis of environmental and genetic factors that are important for child health and disease. Registry data from non-participating women and infants are available which ensures a high degree of comparable data....

    Communication with children plays a crucial role not only for cognitive and social-emotional development but also in a more general sense for an understanding of self and self in relation to others. Research from linguistic anthropology and cultural developmental psychology have shown...... will therefore ultimately lead to different cultural developmental pathways. While traditional research in developmental psychology has focused on mother–child dyads and experimental designs there is an increasing recognition of the need for naturalistic studies of everyday communication with children including...... that there exists a great variety of cultural genres of communicating with children that are in line with the relevant broader cultural ideologies of good child care. Culture, communication, and self- development are inextricably intertwined. Culturally distinct communicative practices in which children participate...

    Immigrant and native child poverty in Denmark, Norway, and Sweden 1993–2001 is studied using large sets of panel data. While native children face yearly poverty risks of less than 10 percent in all three countries and for all years studied the increasing proportion of immigrant children...... with an origin in middle- and low-income countries have poverty risks that vary from 38 up to as much as 58 percent. At the end of the observation period, one third of the poor children in Norway and as high as about a half in Denmark and in Sweden are of immigrant origin. The strong overrepresentation...... of immigrant children from low- and middle-income countries when measured in yearly data is also found when applying a longer accounting period for poverty measurement. We find that child poverty rates are generally high shortly after arrival to the new country and typically decrease with years since...

  17. Cohabitation and Child Wellbeing.

    Manning, Wendy D

    2015-01-01

    In recent decades, writes Wendy Manning, cohabitation has become a central part of the family landscape in the United States-so much so that by age 12, 40 percent of American children will have spent at least part of their lives in a cohabiting household. Although many children are born to cohabiting parents, and cohabiting families come in other forms as well, the most common cohabiting arrangement is a biological mother and a male partner. Cohabitation, Manning notes, is associated with several factors that have the potential to reduce children's wellbeing. Cohabiting families are more likely than married families to be poor, and poverty harms children in many ways. Cohabiting parents also tend to have less formal education-a key indicator of both economic and social resources-than married parents do. And cohabiting parent families don't have the same legal protections that married parent families have. Most importantly, cohabitation is often a marker of family instability, and family instability is strongly associated with poorer outcomes for children. Children born to cohabiting parents see their parents break up more often than do children born to married parents. In this way, being born into a cohabiting family sets the stage for later instability, and children who are born to cohabiting parents appear to experience enduring deficits of psychosocial wellbeing. On the other hand, stable cohabiting families with two biological parents seem to offer many of the same health, cognitive, and behavioral benefits that stable married biological parent families provide. Turning to stepfamilies, cohabitation's effects are tied to a child's age. Among young children, living in a cohabiting stepfamily rather than a married stepfamily is associated with more negative indicators of child wellbeing, but this is not so among adolescents. Thus the link between parental cohabitation and child wellbeing depends on both the type of cohabiting parent family and the age of the

    Child care and early education subsidies are an important part of government efforts to increase economic independence and improve development of children in low-income families in the United States. This chapter describes the main subsidy programs in the U.S., discusses economic issues that arise in designing such programs and evaluating their effects, and surveys evidence on the effects of the programs. An important theme of the chapter is the tradeoff between the policy goals of increasing...

    2014-01-01

    European countries vary in the extent to which they succeed in reducing poverty using social transfers. However, we do not have good ways of understanding how these different outcomes are achieved. It is therefore very difficult to learn lessons from abroad. This paper uses micro data from the EU Statistics on Income and Living Condition (SILC), and attempts to decompose reductions in child poverty rates and gaps into the contribution made by children, old age, social exclusion, housing and w...
