    Human endogenous retrovirus W family (HERV-W) envelope (env) has been reported to be related to several human diseases, including autoimmune disorders, and it could activate innate immunity. However, there are no reports investigating whether human leukemia antigen (HLA)-A*0201 + restriction is involved in the immune response caused by HERV-W env in neuropsychiatric diseases. In the present study, HERV-W env-derived epitopes presented by HLA-A*0201 are described with the potential for use in adoptive immunotherapy. Five peptides displaying HLA-A*0201-binding motifs were predicted using SYFEPITHI and BIMAS, and synthesized. A CCK-8 assay showed peptides W, Q and T promoted lymphocyte proliferation. Stimulation of peripheral blood mononuclear cells from HLA-A*0201 + donors with each of these peptides induced peptide-specific CD8 + T cells. High numbers of IFN-γ-secreting T cells were also detectable after several weekly stimulations with W, Q and T. Besides lysis of HERV-W env-loaded target cells, specific apoptosis was also observed. These data demonstrate that human T cells can be sensitized toward HERV-W env peptides (W, Q and T) and, moreover, pose a high killing potential toward HERV-W env-expressing U251 cells. In conclusion, peptides W Q and T, which are HERV-W env antigenic epitopes, have both antigenicity and immunogenicity, and can cause strong T cell immune responses. Our data strengthen the view that HERV-W env should be considered as an autoantigen that can induce autoimmunity in neuropsychiatric diseases, such as multiple sclerosis and schizophrenia. These data might provide an experimental foundation for a HERV-W env peptide vaccine and new insight into the treatment of neuropsychiatric diseases.

  2. The application of strand invasion phenomenon, directed by peptide nucleic acid (PNA) and single-stranded DNA binding protein (SSB) for the recognition of specific sequences of human endogenous retroviral HERV-W family.

    The HERV-W family of human endogenous retroviruses represents a group of numerous sequences that show close similarity in genetic composition. It has been documented that some members of HERV-W-derived expression products are supposed to play significant role in humans' pathology, such as multiple sclerosis or schizophrenia. Other members of the family are necessary to orchestrate physiological processes (eg, ERVWE1 coding syncytin-1 that is engaged in syncytiotrophoblast formation). Therefore, an assay that would allow the recognition of particular form of HERV-W members is highly desirable. A peptide nucleic acid (PNA)-mediated technique for the discrimination between multiple sclerosis-associated retrovirus and ERVWE1 sequence has been developed. The assay uses a PNA probe that, being fully complementary to the ERVWE1 but not to multiple sclerosis-associated retrovirus (MSRV) template, shows high selective potential. Single-stranded DNA binding protein facilitates the PNA-mediated, sequence-specific formation of strand invasion complex and, consequently, local DNA unwinding. The target DNA may be then excluded from further analysis in any downstream process such as single-stranded DNA-specific exonuclease action. Finally, the reaction conditions have been optimized, and several PNA probes that are targeted toward distinct loci along whole HERV-W env sequences have been evaluated. We believe that PNA/single-stranded DNA binding protein-based application has the potential to selectively discriminate particular HERV-W molecules as they are at least suspected to play pathogenic role in a broad range of medical conditions, from psycho-neurologic disorders (multiple sclerosis and schizophrenia) and cancers (breast cancer) to that of an auto-immunologic background (psoriasis and lupus erythematosus).

  3. The aliens inside us: HERV-W endogenous retroviruses and multiple sclerosis.

    Dolei, Antonina


    Two human endogenous retroviruses of the HERV-W family are proposed as multiple sclerosis (MS) co-factors: MS-associated retrovirus (MSRV) and ERVWE1, whose env proteins showed several potentially neuropathogenic features, in vitro and in animal models. Phase II clinical trials against HERV-Wenv are ongoing. HERV-W/MSRV was repeatedly found in MS patients, in striking parallel with MS stages, active/remission phases, and therapy outcome. The HERV-Wenv protein is highly expressed in active MS plaques. Early MSRV presence in spinal fluids predicted worst MS progression 10 years in advance. Effective anti-MS therapies strongly reduced MSRV/Syncytin-1/HERV-W expression. The Epstein-Barr virus (EBV) activates HERV-W/MSRV in vitro and in vivo, in patients with infectious mononucleosis and controls with high anti-EBNA1-IgG titers. Thus, the two main EBV/MS links (infectious mononucleosis and high anti-EBNA1-IgG titers) are paralleled by activation of HERV-W/MSRV. It is hypothesized that EBV may act as initial trigger of future MS, years later, by activating MSRV, which would act as direct neuropathogenic effector, before and during MS.

  4. Contribution of type W human endogenous retroviruses to the human genome: characterization of HERV-W proviral insertions and processed pseudogenes.

    Grandi, Nicole; Cadeddu, Marta; Blomberg, Jonas; Tramontano, Enzo


    Human endogenous retroviruses (HERVs) are ancient sequences integrated in the germ line cells and vertically transmitted through the offspring constituting about 8 % of our genome. In time, HERVs accumulated mutations that compromised their coding capacity. A prominent exception is HERV-W locus 7q21.2, producing a functional Env protein (Syncytin-1) coopted for placental syncytiotrophoblast formation. While expression of HERV-W sequences has been investigated for their correlation to disease, an exhaustive description of the group composition and characteristics is still not available and current HERV-W group information derive from studies published a few years ago that, of course, used the rough assemblies of the human genome available at that time. This hampers the comparison and correlation with current human genome assemblies. In the present work we identified and described in detail the distribution and genetic composition of 213 HERV-W elements. The bioinformatics analysis led to the characterization of several previously unreported features and provided a phylogenetic classification of two main subgroups with different age and structural characteristics. New facts on HERV-W genomic context of insertion and co-localization with sequences putatively involved in disease development are also reported. The present work is a detailed overview of the HERV-W contribution to the human genome and provides a robust genetic background useful to clarify HERV-W role in pathologies with poorly understood etiology, representing, to our knowledge, the most complete and exhaustive HERV-W dataset up to date.

  5. HBV X Protein induces overexpression of HERV-W env through NF-κB in HepG2 cells.

    Liu, Cong; Liu, Lijuan; Wang, Xiuling; Liu, Youyi; Wang, Miao; Zhu, Fan


    Human endogenous retrovirus W family (HERV-W) envelope (env) at chromosome 7 is highly expressed in the placenta and possesses fusogenic activity in trophoblast development. HERV-W env has been found to be overexpressed in some cancers and immune diseases. Viral transactivators can induce the overexpression of HERV-W env in human cell lines. Hepatitis B virus X protein (HBx) is believed to be a multifunctional oncogenic protein. Here, we reported that HBx could increase the promoter activity of HERV-W env and upregulate the mRNA levels of non-spliced and spliced HERV-W env and also its protein in human hepatoma HepG2 cells. Interestingly, we found that the inhibition of nuclear factor κB (NF-κB) using shRNA targeting NF-κB/p65 or PDTC (an inhibitor of NF-κB) could attenuate the upregulation of HERV-W env induced by HBx. These suggested that HBx might upregulate the expression of HERV-W env through NF-κB in HepG2 cells. This study might provide a new insight in HBV-associated liver diseases including HCC.

  6. Human endogenous retrovirus type W (HERV-W) in schizophrenia: a new avenue of research at the gene-environment interface.

    Leboyer, Marion; Tamouza, Ryad; Charron, Dominique; Faucard, Raphaél; Perron, Hervé


    Provide a synthetic review of recent studies evidencing an association between human endogenous retrovirus-W (HERV-W) and schizophrenia. Bibliography analysis and contextual synthesis. Epidemiological studies suggest that the aetiology of schizophrenia is complex and involves a complex interplay of genetic and environmental factors such as infections. Eight percentof the human genome consists of human endogenous retroviruses (HERV), and this part of the genome was previously thought to be without importance, but new research has refuted this. HERVs share similarities with viruses and it is assumed that HERVs are present in the genome as a result of retroviruses infecting germ line cells many million years ago. A specific type of HERVs, called HERV-W, has through several recent studies been associated with schizophrenia. Elevated transcription of HERV-W elements has been documented, and antigens of HERV-W envelope and capsid proteins have been found in blood samples from patients. Viruses that have been implicated in pathology of schizophrenia, such as herpes and influenza, have been shown to activate HERV-W elements, and such activation has been associated with elevated biomarkers of systemic inflammation. New research indicates that HERV-W may be an important genetic factor interplaying with the environmental risk factor of infections and that, through this, HERV-W may be important for disease pathogenesis. A lifelong scenario of a detrimental interaction between infectious agents and HERV-W genes may decipher the actual development and course of schizophrenia. Further research is needed to find out if specific treatment strategies could reduce the expression of HERV-W and if this will be associated with remission.

  7. Type W Human Endogenous Retrovirus (HERV-W) Integrations and Their Mobilization by L1 Machinery: Contribution to the Human Transcriptome and Impact on the Host Physiopathology.

    Grandi, Nicole; Tramontano, Enzo


    Human Endogenous Retroviruses (HERVs) are ancient infection relics constituting ~8% of our DNA. While HERVs' genomic characterization is still ongoing, impressive amounts of data have been obtained regarding their general expression across tissues. Among HERVs, one of the most studied is the W group, which is the sole HERV group specifically mobilized by the long interspersed element-1 (LINE-1) machinery, providing a source of novel insertions by retrotransposition of HERV-W processed pseudogenes, and comprising a member encoding a functional envelope protein coopted for human placentation. The HERV-W group has been intensively investigated for its putative role in several diseases, such as cancer, inflammation, and autoimmunity. Despite major interest in the link between HERV-W expression and human pathogenesis, no conclusive correlation has been demonstrated so far. In general, (i) the absence of a proper identification of the specific HERV-W sequences expressed in a given condition, and (ii) the lack of studies attempting to connect the various observations in the same experimental conditions are the major problems preventing the definitive assessment of the HERV-W impact on human physiopathology. In this review, we summarize the current knowledge on the HERV-W group presence within the human genome and its expression in physiological tissues as well as in the main pathological contexts.

  8. GABBR1 has a HERV-W LTR in its regulatory region – a possible implication for schizophrenia

    Hegyi Hedi


    Full Text Available Abstract Schizophrenia is a complex disease with uncertain aetiology. We suggest GABBR1, GABA receptor B1 implicated in schizophrenia based on a HERV-W LTR in the regulatory region of GABBR1. Our hypothesis is supported by: (i GABBR1 is in the 6p22 genomic region most often implicated in schizophrenia; (ii microarray studies found that only presynaptic pathway-related genes, including GABA receptors, have altered expression in schizophrenic patients and (iii it explains how HERV-W elements, expressed in schizophrenia, play a role in the disease: by altering the expression of GABBR1 via a long terminal repeat that is also a regulatory element to GABBR1.

  9. HERV-W group evolutionary history in non-human primates: characterization of ERV-W orthologs in Catarrhini and related ERV groups in Platyrrhini.

    Grandi, Nicole; Cadeddu, Marta; Blomberg, Jonas; Mayer, Jens; Tramontano, Enzo


    The genomes of all vertebrates harbor remnants of ancient retroviral infections, having affected the germ line cells during the last 100 million years. These sequences, named Endogenous Retroviruses (ERVs), have been transmitted to the offspring in a Mendelian way, being relatively stable components of the host genome even long after their exogenous counterparts went extinct. Among human ERVs (HERVs), the HERV-W group is of particular interest for our physiology and pathology. A HERV-W provirus in locus 7q21.2 has been coopted during evolution to exert an essential role in placenta, and the group expression has been tentatively linked to Multiple Sclerosis and other diseases. Following up on a detailed analysis of 213 HERV-W insertions in the human genome, we now investigated the ERV-W group genomic spread within primate lineages. We analyzed HERV-W orthologous loci in the genome sequences of 12 non-human primate species belonging to Simiiformes (parvorders Catarrhini and Platyrrhini), Tarsiiformes and to the most primitive Prosimians. Analysis of HERV-W orthologous loci in non-human Catarrhini primates revealed species-specific insertions in the genomes of Chimpanzee (3), Gorilla (4), Orangutan (6), Gibbon (2) and especially Rhesus Macaque (66). Such sequences were acquired in a retroviral fashion and, in the majority of cases, by L1-mediated formation of processed pseudogenes. There were also a number of LTR-LTR homologous recombination events that occurred subsequent to separation of Catarrhini sub-lineages. Moreover, we retrieved 130 sequences in Marmoset and Squirrel Monkeys (family Cebidae, Platyrrhini parvorder), identified as ERV1-1_CJa based on RepBase annotations, which appear closely related to the ERV-W group. Such sequences were also identified in Atelidae and Pitheciidae, representative of the other Platyrrhini families. In contrast, no ERV-W-related sequences were found in genome sequence assemblies of Tarsiiformes and Prosimians. Overall, our

  10. A new therapeutic approach for type 1 diabetes: rationale for GNbAC1 an anti-HERV-W-Env monoclonal antibody.

    Curtin, Francois; Bernard, Corinne; Levet, Sandrine; Perron, Hervé; Porchet, Hervé; Médina, Julie; Malpass, Sam; Lloyd, David; Simpson, Richard


    We describe a newly identified therapeutic target for type 1 diabetes: an envelope protein of endogenous retroviral origin called Human Endogenous Retrovirus W Envelope (HERV-W-Env). HERV-W-Env was found to be detected in the blood of around 60% of type 1 diabetes (T1D) patients and is expressed in acinar pancreatic cells of 75% of T1D patients at post-mortem examination. Preclinical experiments showed that this protein displays direct cytotoxicity on human β-islet cells. In vivo HERV-W-Env impairs the insulin and glucose metabolism in transgenic mice expressing HERV-W-Env. GNbAC1, an IgG4 monoclonal antibody has been developed to specifically target HERV-W-Env and to neutralize the effect of HERV-W-Env in vitro and in vivo. GNbAC1 is currently in clinical development for multiple sclerosis and more than 300 subjects have been administered with GNbAC1 so far. GNbAC1 is now tested in T1D in the RAINBOW-T1D study: a randomized placebo controlled study with the objective of showing the safety and pharmacodynamics response of GNbAC1 in patients suffering from T1D with a maximum duration of 4 years. GNbAC1 is tested versus placebo at the dose of 6 mg/kg in 60 patients during 6 repeated administrations during 6 months, a 6-month open-label extension will follow. The primary endpoint will assess safety and secondary endpoints the pharmacodynamic responses to GNbAC1. GNbAC1 targeting HERV-W-Env is currently in clinical development in T1D with the first safety and pharmacodynamic study. If the study results are positive, this may open the door to the development of an innovative non-immunomodulatory disease modifying treatment for T1D. This article is protected by copyright.

  11. The sieve element occlusion gene family in dicotyledonous plants.

    Ernst, Antonia M; Rüping, Boris; Jekat, Stephan B; Nordzieke, Steffen; Reineke, Anna R; Müller, Boje; Bornberg-Bauer, Erich; Prüfer, Dirk; Noll, Gundula A


    Sieve element occlusion (SEO) genes encoding forisome subunits have been identified in Medicago truncatula and other legumes. Forisomes are structural phloem proteins uniquely found in Fabaceae sieve elements. They undergo a reversible conformational change after wounding, from a condensed to a dispersed state, thereby blocking sieve tube translocation and preventing the loss of photoassimilates. Recently, we identified SEO genes in several non-Fabaceae plants (lacking forisomes) and concluded that they most probably encode conventional non-forisome P-proteins. Molecular and phylogenetic analysis of the SEO gene family has identified domains that are characteristic for SEO proteins. Here, we extended our phylogenetic analysis by including additional SEO genes from several diverse species based on recently published genomic data. Our results strengthen the original assumption that SEO genes seem to be widespread in dicotyledonous angiosperms, and further underline the divergent evolution of SEO genes within the Fabaceae.

  12. ABFs, a family of ABA-responsive element binding factors.

    Choi, H; Hong, J; Ha, J; Kang, J; Kim, S Y


    Abscisic acid (ABA) plays an important role in environmental stress responses of higher plants during vegetative growth. One of the ABA-mediated responses is the induced expression of a large number of genes, which is mediated by cis-regulatory elements known as abscisic acid-responsive elements (ABREs). Although a number of ABRE binding transcription factors have been known, they are not specifically from vegetative tissues under induced conditions. Considering the tissue specificity of ABA signaling pathways, factors mediating ABA-dependent stress responses during vegetative growth phase may thus have been unidentified so far. Here, we report a family of ABRE binding factors isolated from young Arabidopsis plants under stress conditions. The factors, isolated by a yeast one-hybrid system using a prototypical ABRE and named as ABFs (ABRE binding factors) belong to a distinct subfamily of bZIP proteins. Binding site selection assay performed with one ABF showed that its preferred binding site is the strong ABRE, CACGTGGC. ABFs can transactivate an ABRE-containing reporter gene in yeast. Expression of ABFs is induced by ABA and various stress treatments, whereas their induction patterns are different from one another. Thus, a new family of ABRE binding factors indeed exists that have the potential to activate a large number of ABA/stress-responsive genes in Arabidopsis.

  14. Soap opera families: some elements of social representations

    Paulo Rogério Meira Menandro


    Full Text Available Soap operas are a cultural phenomenon of recognized importance in Brazilian society. They have come into the atention of investigators since they represent concrete social processes that are not strange to the spectator´s reality. A large variety of social themes have already been discussed in soap operas, characterizing a broad spectrum which covers from daily ordinary events up to controversial situation of rupture, forcing public debate. This investigation at empted to identify and analyze how family arrangements, as well as familial and conjugal daily routine, were portrayed in six soap opera plots exhibited between 2003 and 2008 by Rede Globo network. The data collection was performed by the analysis of the soap operas chapter synopses, and the data was organized and discussed using the classic content analysis technique. The way Brazilian family is portrayed in the weekly TV fiction incorporates new family arrangements, presenting new relationship construction possibilities originated during the last decades, in opposition to the conservative raditions

  17. Work, family, and gender: elements for a theory of work-family balance.

    Cantera, Leonor M; Cubells, Ma Eugenia; Martínez, Luz Ma; Blanch, Josep M


    Over last century, work was not only a means of economic survival, but also a very strong factor of psychological structuring and of organization of personal, family, and everyday life. The new world of work provides new challenges to the balance of work and family life. A questionnaire was administered to a sample of 453 people with the aim of analyzing the relation between variables such as family burdens and domestic responsibilities, and the appraisal of work and family, values involved in work-family balance. The results of this study show that, in the present economic and cultural context, assuming family burdens and domestic responsibilities increases the positive appraisal of work and family, both in men and women. This has theoretical and practical implications concerning the challenge of work-family balance.

  19. Profiling Fast Healthcare Interoperability Resources (FHIR) of Family Health History based on the Clinical Element Models.

    Lee, Jaehoon; Hulse, Nathan C; Wood, Grant M; Oniki, Thomas A; Huff, Stanley M


    In this study we developed a Fast Healthcare Interoperability Resources (FHIR) profile to support exchanging a full pedigree based family health history (FHH) information across multiple systems and applications used by clinicians, patients, and researchers. We used previously developed clinical element models (CEMs) that are capable of representing the FHH information, and derived essential data elements including attributes, constraints, and value sets. We analyzed gaps between the FHH CEM elements and existing FHIR resources. Based on the analysis, we developed a profile that consists of 1) FHIR resources for essential FHH data elements, 2) extensions for additional elements that were not covered by the resources, and 3) a structured definition to integrate patient and family member information in a FHIR message. We implemented the profile using an open-source based FHIR framework and validated it using patient-entered FHH data that was captured through a locally developed FHH tool.

  1. CMV induces HERV-K and HERV-W expression in kidney transplant recipients.

    Bergallo, Massimiliano; Galliano, Ilaria; Montanari, Paola; Gambarino, Stefano; Mareschi, Katia; Ferro, Francesca; Fagioli, Franca; Tovo, Pier-Angelo; Ravanini, Paolo


    Human endogenous retrovirus (HERVs) constitute approximately 8% of the human genome. Induction of HERV transcription is possible under certain circumstances, and may have a possible role in some pathological conditions. The aim of this study was to evaluate HERV-K and -W pol gene expression in kidney transplant recipients and to investigate the possible relationship between HERVs gene expression and CMV infection in these patients. Thirty-three samples of kidney transplant patients and twenty healthy blood donors were used to analyze, HERV-K and -W pol gene RNA expression by relative quantitative relative Real-Time PCR. We demonstrated that HERVs pol gene expression levels were higher in kidney transplant recipients than in healthy subjects. Moreover, HERV-K and -W pol gene expression was significantly higher in the group of kidney transplant recipients with high CMV viral load than in the groups with no or moderate CMV viral load. Our data suggest that CMV may facilitate in vivo HERV activation. Published by Elsevier B.V.

  2. BoS: a large and diverse family of short interspersed elements (SINEs) in Brassica oleracea.

    Zhang, Xiaoyu; Wessler, Susan R


    Short interspersed elements (SINEs) are nonautonomous non-LTR retrotransposons that populate eukaryotic genomes. Numerous SINE families have been identified in animals, whereas only a few have been described in plants. Here we describe a new family of SINEs, named BoS, that is widespread in Brassicaceae and present at approximately 2000 copies in Brassica oleracea. In addition to sharing a modular structure and target site preference with previously described SINEs, BoS elements have several unusual features. First, the head regions of BoS RNAs can adopt a distinct hairpin-like secondary structure. Second, with 15 distinct subfamilies, BoS represents one of the most diverse SINE families described to date. Third, several of the subfamilies have a mosaic structure that has arisen through the exchange of sequences between existing subfamilies, possibly during retrotransposition. Analysis of BoS subfamilies indicate that they were active during various time periods through the evolution of Brassicaceae and that active elements may still reside in some Brassica species. As such, BoS elements may be a valuable tool as phylogenetic makers for resolving outstanding issues in the evolution of species in the Brassicaceae family.

  3. Key Elements of a Family Intervention for Schizophrenia: A Qualitative Analysis of an RCT.

    Grácio, Jaime; Gonçalves-Pereira, Manuel; Leff, Julian


    Schizophrenia is a complex biopsychosocial condition in which expressed emotion in family members is a robust predictor of relapse. Not surprisingly, family interventions are remarkably effective and thus recommended in current treatment guidelines. Their key elements seem to be common therapeutic factors, followed by education and coping skills training. However, few studies have explored these key elements and the process of the intervention itself. We conducted a qualitative and quantitative analysis of the records from a pioneering family intervention trial addressing expressed emotion, published by Leff and colleagues four decades ago. Records were analyzed into categories and data explored using descriptive statistics. This was complemented by a narrative evaluation using an inductive approach based on emotional markers and markers of change. The most used strategies in the intervention were addressing needs, followed by coping skills enhancement, advice, and emotional support. Dealing with overinvolvement and reframing were the next most frequent. Single-family home sessions seemed to augment the therapeutic work conducted in family groups. Overall the intervention seemed to promote cognitive and emotional change in the participants, and therapists were sensitive to the emotional trajectory of each subject. On the basis of our findings, we developed a longitudinal framework for better understanding the process of this treatment approach. © 2016 Family Process Institute.

  4. Background and elements of the linkage between the Brazilian school feeding program and family farming.

    Schwartzman, Flavia; Mora, Claudia Andrea Rodriguez; Bogus, Claudia Maria; Villar, Betzabeth Slater


    Since 2009, legislation of the National School Feeding Program of Brazil (PNAE) institutionalizes its linkage with family farming as it establishes the requirement that at least 30% out of the total financial resources allocated by the federal government to the states and municipalities for school feeding must be used in the purchase of products directly from this sector. This study analyzes the process of drafting this legislation, focusing on the elements related to the procurement from family farming, through a historical contextualization, and it also presents a graphical representation with the main elements of this linkage: its objectives, target population, actions implemented and expected results. Actors involved with the drafting of the legislation were interviewed. The analyses show that the procurement from family farming is a far-reaching initiative in terms of the concept, execution and results. It has also showed that a strong articulation between the actors and institutions of the different sectors involved is critical to its success. The education, agriculture, planning, procurement and civil society sectors should work articulately at national, state and local level. The results of this study demonstrate that initiatives like this, of institutional procurement from family farming, which are currently being implemented in several countries, constitute as an important strategy of food and nutrition security, for the fulfillment of the human right to adequate food and the promotion of long-term sustainable development.

  5. Redefinition and unification of the SXT/R391 family of integrative and conjugative elements.

    Bioteau, Audrey; Durand, Romain; Burrus, Vincent


    Integrative and conjugative elements (ICEs) of the SXT/R391 family are key drivers of the spread of antibiotic resistance in Vibrio cholerae , the infectious agent of cholera, and other pathogenic bacteria. The SXT/R391 family of ICEs was defined based on the conservation of a core set of 52 genes and site-specific integration into the 5' end of the chromosomal gene prfC Hence, the integrase gene int has been intensively used as a marker to detect SXT/R391 ICEs in clinical isolates. ICEs sharing most core genes but differing by their integration site and integrase gene have been recently reported and excluded from the SXT/R391 family. Here we explored the prevalence and diversity of atypical ICEs in Genbank databases and their relationship with typical SXT/R391 ICEs. We found atypical ICEs in V. cholerae isolates that predate the emergence and expansion of typical SXT/R391 ICEs in the mid-1980s in seventh pandemic toxigenic V. cholerae O1 and O139 strains. Our analyses revealed that while atypical ICEs are not associated with antibiotic resistance genes, they often carry cation efflux pumps suggesting heavy metal resistance. Atypical ICEs constitute a polyphyletic group likely because of occasional recombination events with typical ICEs. Furthermore, we show that the alternative integration and excision genes of atypical ICEs remain under the control of SetCD, the main activator of the conjugative functions of SXT/R391 ICEs. Together these observations indicate that substitution of the integration/excision module and change of specificity of integration do not preclude atypical ICEs from inclusion into the SXT/R391 family. Importance Vibrio cholerae is the causative agent of cholera, an acute intestinal infection that remains to this day a world public health threat. Integrative and conjugative elements (ICEs) of the SXT/R391 family have played a major role in spreading antimicrobial resistance in seventh pandemic V. cholerae but also in several species of

  6. Evolutionary modes of emergence of short interspersed nuclear element (SINE) families in grasses.

    Kögler, Anja; Schmidt, Thomas; Wenke, Torsten


    Short interspersed nuclear elements (SINEs) are non-autonomous transposable elements which are propagated by retrotransposition and constitute an inherent part of the genome of most eukaryotic species. Knowledge of heterogeneous and highly abundant SINEs is crucial for de novo (or improvement of) annotation of whole genome sequences. We scanned Poaceae genome sequences of six important cereals (Oryza sativa, Triticum aestivum, Hordeum vulgare, Panicum virgatum, Sorghum bicolor, Zea mays) and Brachypodium distachyon to examine the diversity and evolution of SINE populations. We comparatively analyzed the structural features, distribution, evolutionary relation and abundance of 32 SINE families and subfamilies within grasses, comprising 11 052 individual copies. The investigation of activity profiles within the Poaceae provides insights into their species-specific diversification and amplification. We found that Poaceae SINEs (PoaS) fall into two length categories: simple SINEs of up to 180 bp and dimeric SINEs larger than 240 bp. Detailed analysis at the nucleotide level revealed that multimerization of related and unrelated SINE copies is an important evolutionary mechanism of SINE formation. We conclude that PoaS families diversify by massive reshuffling between SINE families, likely caused by insertion of truncated copies, and provide a model for this evolutionary scenario. Twenty-eight of 32 PoaS families and subfamilies show significant conservation, in particular either in the 5' or 3' regions, across Poaceae species and share large sequence stretches with one or more other PoaS families. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

    Carmo, Andrius M.J.; Paiva, Jose Daniel S. de; Magalhaes, Marcelo R.L. de; Franca, Elvis J. de; Hazin, Clovis A.; Bacchi, Marcio A.; Fernandes, Elisabete A.N.


    This study aims to evaluate the distribution of K, Rb and Cs in leaves of trees of the Atlantic Forest through studies of correlation between the chemical elements. For this, we used the Instrumental Neutron Activation Analysis for the quantification of the chemical elements. The concentration ranges found were 6700-24000 mg / kg for K, 16 to 72mg / kg for Rb and 0.08 to 0,92mg / kg for Cs. As Rb has chemical similarity to K, is easily absorbed by plants, leading to a high value (0.9) of the Pearson correlation. For the correlation between K and Cs, no significant values were detected except for some species of the Myrtaceae family. However, average correlations (0.6 < r <0.8) between Rb-Cs were obtained for seven plant species of different families. The absence of a specific pattern using of K, Rb and Cs by plants showed great complexity in the distribution of chemical elements in the ecosystem

  8. A Family of Multipoint Flux Mixed Finite Element Methods for Elliptic Problems on General Grids

    Wheeler, Mary F.


    In this paper, we discuss a family of multipoint flux mixed finite element (MFMFE) methods on simplicial, quadrilateral, hexahedral, and triangular-prismatic grids. The MFMFE methods are locally conservative with continuous normal fluxes, since they are developed within a variational framework as mixed finite element methods with special approximating spaces and quadrature rules. The latter allows for local flux elimination giving a cell-centered system for the scalar variable. We study two versions of the method: with a symmetric quadrature rule on smooth grids and a non-symmetric quadrature rule on rough grids. Theoretical and numerical results demonstrate first order convergence for problems with full-tensor coefficients. Second order superconvergence is observed on smooth grids. © 2011 Published by Elsevier Ltd.

    Vertical organizations of skeletal elements are found in various vertebrate teeth and invertebrate exoskeletons. The molecular mechanism behind the development of such structural organizations is poorly known, although it is generally held that organic matrix proteins play an essential role. While most crustacean cuticular organizations exhibit horizontal chitinous layering, a typical vertical organization is found towards the surface of the teeth in the mandibles of the crayfish Cherax quadricarinatus. Candidate genes encoding for mandible-forming structural proteins were mined in C. quadricarinatus molt-related transcriptomic libraries by using a binary patterning approach. A new protein family, termed the Mandible Alanine Rich Structural (MARS) protein family, with a modular sequence design predicted to form fibers, was found. Investigations of spatial and temporal expression of the different MARS genes suggested specific expression in the mandibular teeth-forming epithelium, particularly during the formation of the chitinous vertical organization. MARS loss-of-function RNAi experiments resulted in the collapse of the organization of the chitin fibers oriented vertically to the surface of the crayfish mandibular incisor tooth. A general search of transcriptomic libraries suggested conservation of MARS proteins across a wide array of crustaceans. Our results provide a first look into the molecular mechanism used to build the complex crustacean mandible and into the specialized vertical structural solution that has evolved in skeletal elements.

  13. Genome-wide comparative analysis of 20 miniature inverted-repeat transposable element families in Brassica rapa and B. oleracea.

    Perumal Sampath

    Full Text Available Miniature inverted-repeat transposable elements (MITEs are ubiquitous, non-autonomous class II transposable elements. Here, we conducted genome-wide comparative analysis of 20 MITE families in B. rapa, B. oleracea, and Arabidopsis thaliana. A total of 5894 and 6026 MITE members belonging to the 20 families were found in the whole genome pseudo-chromosome sequences of B. rapa and B. oleracea, respectively. Meanwhile, only four of the 20 families, comprising 573 members, were identified in the Arabidopsis genome, indicating that most of the families were activated in the Brassica genus after divergence from Arabidopsis. Copy numbers varied from 4 to 1459 for each MITE family, and there was up to 6-fold variation between B. rapa and B. oleracea. In particular, analysis of intact members showed that whereas eleven families were present in similar copy numbers in B. rapa and B. oleracea, nine families showed copy number variation ranging from 2- to 16-fold. Four of those families (BraSto-3, BraTo-3, 4, 5 were more abundant in B. rapa, and the other five (BraSto-1, BraSto-4, BraTo-1, 7 and BraHAT-1 were more abundant in B. oleracea. Overall, 54% and 51% of the MITEs resided in or within 2 kb of a gene in the B. rapa and B. oleracea genomes, respectively. Notably, 92 MITEs were found within the CDS of annotated genes, suggesting that MITEs might play roles in diversification of genes in the recently triplicated Brassica genome. MITE insertion polymorphism (MIP analysis of 289 MITE members showed that 52% and 23% were polymorphic at the inter- and intra-species levels, respectively, indicating that there has been recent MITE activity in the Brassica genome. These recently activated MITE families with abundant MIP will provide useful resources for molecular breeding and identification of novel functional genes arising from MITE insertion.

  14. Targeted identification of short interspersed nuclear element families shows their widespread existence and extreme heterogeneity in plant genomes.

    Wenke, Torsten; Döbel, Thomas; Sörensen, Thomas Rosleff; Junghans, Holger; Weisshaar, Bernd; Schmidt, Thomas


    Short interspersed nuclear elements (SINEs) are non-long terminal repeat retrotransposons that are highly abundant, heterogeneous, and mostly not annotated in eukaryotic genomes. We developed a tool designated SINE-Finder for the targeted discovery of tRNA-derived SINEs. We analyzed sequence data of 16 plant genomes, including 13 angiosperms and three gymnosperms and identified 17,829 full-length and truncated SINEs falling into 31 families showing the widespread occurrence of SINEs in higher plants. The investigation focused on potato (Solanum tuberosum), resulting in the detection of seven different SolS SINE families consisting of 1489 full-length and 870 5' truncated copies. Consensus sequences of full-length members range in size from 106 to 244 bp depending on the SINE family. SolS SINEs populated related species and evolved separately, which led to some distinct subfamilies. Solanaceae SINEs are dispersed along chromosomes and distributed without clustering but with preferred integration into short A-rich motifs. They emerged more than 23 million years ago and were species specifically amplified during the radiation of potato, tomato (Solanum lycopersicum), and tobacco (Nicotiana tabacum). We show that tobacco TS retrotransposons are composite SINEs consisting of the 3' end of a long interspersed nuclear element integrated downstream of a nonhomologous SINE family followed by successfully colonization of the genome. We propose an evolutionary scenario for the formation of TS as a spontaneous event, which could be typical for the emergence of SINE families.

  17. Is HERV-K and HERV-W expression regulated by mir-155 in Sézary syndrome?

    Bergallo, Massimiliano; Daprà, Valentina; Novelli, Mauro; Rassu, Marco; Montanari, Paola; Galliano, Ilaria; Quaglino, Pietro; Fierro, Maria T


    According to the latest update, 2578 unique mature miRNAs are currently annotated in the human genome and participate in the regulation of multiple events, such as cellular proliferation or apoptosis. A previous study analyzing global miRNA expression patterns in GH cells (high HERV-K versus low) showed that two miRNAs (miR-663 and miR-638) are differentially regulated and exhibit expression parallel to that of HERV-K. The aim of this study was to evaluate HERV-K and -W pol gene and mir-155 expression in SS patients and possible relationship between them. The comparison between SS patients and healthy donor showed a significant difference in terms of mir-155 expression p=0.0003 as previously reported by our groups. We demonstrated that HERV-K and -W pol gene expression was significantly higher in SS patients vs healthy donor as previously reported by our groups. Our correlation data suggest that miR-155 are not directly involved in regulating the HERVs. Furthermore, further studies including other cohorts of pathology with mir-155 and HERVs involvement such as inflammatory diseases are needed to investigate the role of mir-155 in the cross-activations of HERVs.

  20. Family Involvement as a Priority Element for an Educational Action Based on Dialogic Learning

    Valls, Mercè Pañellas; de Nicolás, Montserrat Alguacil; Torremorell, Maria Carme Boqué

    In our society, there is a need for a critical reflection on education and the tasks to be developed by every agent. The family and school are the two main socializing settings of children and adolescents and, therefore, their joint responsibility in their education is a commitment that should be established in an atmosphere of confidence and harmony in order to tend towards a learning community model based on dialogic learning.

  1. A novel abundant family of retroposed elements (DAS-SINEs) in the nine-banded armadillo (Dasypus novemcinctus).

    Churakov, Gennady; Smit, Arian F A; Brosius, Jürgen; Schmitz, Jürgen


    About half of the mammalian genome is composed of retroposons. Long interspersed elements (LINEs) and short interspersed elements (SINEs) are the most abundant repetitive elements and account for about 21% and 13% of the human genome, respectively. SINEs have been detected in all major mammalian lineages, except for the South American order Xenarthra, also termed Edentata (armadillos, anteaters, and sloths). Investigating this order, we discovered a novel high-copy-number family of tRNA derived SINEs in the nine-banded armadillo Dasypus novemcinctus, a species that successfully crossed the Central American land bridge to North America in the Pliocene. A specific computer algorithm was developed, and we detected and extracted 687 specific SINEs from databases. Termed DAS-SINEs, we further divided them into six distinct subfamilies. We extracted tRNA(Ala)-derived monomers, two types of dimers, and three subfamilies of chimeric fusion products of a tRNA(Ala) domain and an approximately 180-nt sequence of thus far unidentified origin. Comparisons of secondary structures of the DAS-SINEs' tRNA domains suggest selective pressure to maintain a tRNA-like D-arm structure in the respective founder RNAs, as shown by compensatory mutations. By analysis of subfamily-specific genetic variability, comparison of the proportion of direct repeats, and analysis of self-integrations as well as key events of dimerization and deletions or insertions, we were able to delineate the evolutionary history of the DAS-SINE subfamilies.

  2. Diversification, evolution and methylation of short interspersed nuclear element families in sugar beet and related Amaranthaceae species.

    Schwichtenberg, Katrin; Wenke, Torsten; Zakrzewski, Falk; Seibt, Kathrin M; Minoche, André; Dohm, Juliane C; Weisshaar, Bernd; Himmelbauer, Heinz; Schmidt, Thomas


    Short interspersed nuclear elements (SINEs) are non-autonomous non-long terminal repeat retrotransposons which are widely distributed in eukaryotic organisms. While SINEs have been intensively studied in animals, only limited information is available about plant SINEs. We analysed 22 SINE families from seven genomes of the Amaranthaceae family and identified 34 806 SINEs, including 19 549 full-length copies. With the focus on sugar beet (Beta vulgaris), we performed a comparative analysis of the diversity, genomic and chromosomal organization and the methylation of SINEs to provide a detailed insight into the evolution and age of Amaranthaceae SINEs. The lengths of consensus sequences of SINEs range from 113 nucleotides (nt) up to 224 nt. The SINEs show dispersed distribution on all chromosomes but were found with higher incidence in subterminal euchromatic chromosome regions. The methylation of SINEs is increased compared with their flanking regions, and the strongest effect is visible for cytosines in the CHH context, indicating an involvement of asymmetric methylation in the silencing of SINEs. © 2015 The Authors The Plant Journal © 2015 John Wiley & Sons Ltd.

  3. P53 family members modulate the expression of PRODH, but not PRODH2, via intronic p53 response elements.

    Ivan Raimondi

    Full Text Available The tumor suppressor p53 was previously shown to markedly up-regulate the expression of the PRODH gene, encoding the proline dehydrogenase (PRODH enzyme, which catalyzes the first step in proline degradation. Also PRODH2, which degrades 4-hydroxy-L-proline, a product of protein (e.g. collagen catabolism, was recently described as a p53 target. Here, we confirmed p53-dependent induction of endogenous PRODH in response to genotoxic damage in cell lines of different histological origin. We established that over-expression of TAp73β or TAp63β is sufficient to induce PRODH expression in p53-null cells and that PRODH expression parallels the modulation of endogenous p73 by genotoxic drugs in several cell lines. The p53, p63, and p73-dependent transcriptional activation was linked to specific intronic response elements (REs, among those predicted by bioinformatics tools and experimentally validated by a yeast-based transactivation assay. p53 occupancy measurements were validated in HCT116 and MCF7 human cell lines. Conversely, PRODH2 was not responsive to p63 nor p73 and, at best, could be considered a weak p53 target. In fact, minimal levels of PRODH2 transcript induction by genotoxic stress was observed exclusively in one of four p53 wild-type cell lines tested. Consistently, all predicted p53 REs in PRODH2 were poor matches to the p53 RE consensus and showed very weak responsiveness, only to p53, in the functional assay. Taken together, our results highlight that PRODH, but not PRODH2, expression is under the control of p53 family members, specifically p53 and p73. This supports a deeper link between proteins of the p53-family and metabolic pathways, as PRODH modulates the balance of proline and glutamate levels and those of their derivative alpha-keto-glutarate (α-KG under normal and pathological (tumor conditions.

  4. The Salmon Smai Family of Short Interspersed Repetitive Elements (Sines): Interspecific and Intraspecific Variation of the Insertion of Sines in the Genomes of Chum and Pink Salmon

    Takasaki, N.; Yamaki, T.; Hamada, M.; Park, L.; Okada, N.


    The genomes of chum salmon and pink salmon contain a family of short interspersed repetitive elements (SINEs), designated the salmon SmaI family. It is restricted to these two species, a distribution that suggests that this SINE family might have been generated in their common ancestor. When insertions of the SmaI SINEs at 10 orthologous loci of these species were analyzed, however, it was found that there were no shared insertion sites between chum and pink salmon. Furthermore, at six loci w...

  5. Primer-Independent DNA Synthesis by a Family B DNA Polymerase from Self-Replicating Mobile Genetic Elements

    Modesto Redrejo-Rodríguez


    Full Text Available Family B DNA polymerases (PolBs play a central role during replication of viral and cellular chromosomes. Here, we report the discovery of a third major group of PolBs, which we denote primer-independent PolB (piPolB, that might be a link between the previously known protein-primed and RNA/DNA-primed PolBs. PiPolBs are encoded by highly diverse mobile genetic elements, pipolins, integrated in the genomes of diverse bacteria and also present as circular plasmids in mitochondria. Biochemical characterization showed that piPolB displays efficient DNA polymerization activity that can use undamaged and damaged templates and is endowed with proofreading and strand displacement capacities. Remarkably, the protein is also capable of template-dependent de novo DNA synthesis, i.e., DNA-priming activity, thereby breaking the long-standing dogma that replicative DNA polymerases require a pre-existing primer for DNA synthesis. We suggest that piPolBs are involved in self-replication of pipolins and may also contribute to bacterial DNA damage tolerance.

  6. Variation on a theme; an overview of the Tn916 / Tn1545 family of mobile genetic elements in the oral and nasopharyngeal streptococci.

    Francesco eSantoro


    Full Text Available The oral and nasopharyngeal streptococci are a major part of the normal microbiota in humans. Most human associated streptococci are considered commensals however a small number of them are pathogenic, causing a wide range of diseases including oral infections such as dental caries and periodontitis and diseases at other body sites including sinusitis and endocarditis, and in the case of Streptococcus pneumoniae, meningitis. Both phenotypic and sequence based studies have shown that the human associated streptococci from the mouth and nasopharynx harbour a large number of antibiotic resistance genes and these are often located on mobile genetic elements known as conjugative transposons or integrative and conjugative elements of the Tn916 / Tn1545 family. These mobile genetic elements are responsible for the spread of the resistance genes between streptococci and also between streptococci and other bacteria. In this review we describe the resistances conferred by, and the genetic variations between the many different Tn916-like elements found in recent studies of oral and nasopharyngeal streptococci and show that Tn916-like elements are important mediators of antibiotic resistance genes within this genus. We will also discuss the role of the oral environment and how this is conducive to the transfer of these elements and discuss the contribution of both transformation and conjugation on the transfer and evolution of these elements in different streptococci.

  7. In silico analysis of cis-acting regulatory elements in 5' regulatory regions of sucrose transporter gene families in rice (Oryza sativa Japonica) and Arabidopsis thaliana.

    Ibraheem, Omodele; Botha, Christiaan E J; Bradley, Graeme


    The regulation of gene expression involves a multifarious regulatory system. Each gene contains a unique combination of cis-acting regulatory sequence elements in the 5' regulatory region that determines its temporal and spatial expression. Cis-acting regulatory elements are essential transcriptional gene regulatory units; they control many biological processes and stress responses. Thus a full understanding of the transcriptional gene regulation system will depend on successful functional analyses of cis-acting elements. Cis-acting regulatory elements present within the 5' regulatory region of the sucrose transporter gene families in rice (Oryza sativa Japonica cultivar-group) and Arabidopsis thaliana, were identified using a bioinformatics approach. The possible cis-acting regulatory elements were predicted by scanning 1.5kbp of 5' regulatory regions of the sucrose transporter genes translational start sites, using Plant CARE, PLACE and Genomatix Matinspector professional databases. Several cis-acting regulatory elements that are associated with plant development, plant hormonal regulation and stress response were identified, and were present in varying frequencies within the 1.5kbp of 5' regulatory region, among which are; A-box, RY, CAT, Pyrimidine-box, Sucrose-box, ABRE, ARF, ERE, GARE, Me-JA, ARE, DRE, GA-motif, GATA, GT-1, MYC, MYB, W-box, and I-box. This result reveals the probable cis-acting regulatory elements that possibly are involved in the expression and regulation of sucrose transporter gene families in rice and Arabidopsis thaliana during cellular development or environmental stress conditions.

    Nissen, Steffen; Schrøder, H D


    A family with "ant-egg" cataract in three generations is described. The cataract is congenital, probably of autosomal dominant inheritance. Light microscopy of the ant-eggs showed that they are made up of a peripheral zone of lens material and a large almost homogenous centre. Element analysis by......-ray spectrophotometry showed a high content of calcium and phosphorus in the centre. The cataract has been easy to operate on and the postoperative visual results have been good....

  9. A new psammosteid (Agnatha, Heterostraci from the Amata Regional Stage of the Main Devonian Field and morpho-histological types of discrete micromeric elements in the family Psammosteidae

    Vadim N. Glinskiy


    Full Text Available In memory of an outstanding palaeoichthyologist Elga Mark-Kurik The range of diversity of psammosteids from the family Psammosteidae is still poorly known. Here a new species, Psammosteus ramosus sp. nov. Glinskiy, from the Amata Regional Stage of the Main Devonian Field is described. Its morphology, ornamentation, histology of exoskeletal plates, and micromeric elements are compared with those of other representatives of the family Psammosteidae. The comparison shows a close relationship of the new species with Psammosteus falcatus Obruchev, P. kiaeri Halstead Tarlo and P. pectinatus Obruchev, a group of species that is significantly different from other representatives of the genus Psammosteus and constitutes a separate evolutionary lineage. On the basis of morphological and histological features we here differentiate in the fields of tesserae of Psammosteidae the discrete micromeric elements of the ‘basic type’, known in Psammosteus bergi (Obruchev, P. levis Obruchev, P. livonicus Obruchev, P. maeandrinus Agassiz, P. megalopteryx (Trautschold, P. praecursor Obruchev and Karelosteus weberi Obruchev, and micromeric elements of the ‘progressive type’, known in Psammosteus falcatus, P. cf. kiaeri and P. ramosus sp. nov. Glinskiy.

    This study aims to evaluate the distribution of K, Rb and Cs in leaves of trees of the Atlantic Forest through studies of correlation between the chemical elements. For this, we used the Instrumental Neutron Activation Analysis for the quantification of the chemical elements. The concentration ranges found were 6700-24000 mg / kg for K, 16 to 72mg / kg for Rb and 0.08 to 0,92mg / kg for Cs. As Rb has chemical similarity to K, is easily absorbed by plants, leading to a high value (0.9) of the Pearson correlation. For the correlation between K and Cs, no significant values were detected except for some species of the Myrtaceae family. However, average correlations (0.6 families. The absence of a specific pattern using of K, Rb and Cs by plants showed great complexity in the distribution of chemical elements in the ecosystem.

  11. Identification and characterization of new members of the SXT/R391 family of integrative and conjugative elements (ICEs) in Proteus mirabilis.

    Bie, Luyao; Wu, Hao; Wang, Xin-Hua; Wang, Mingyu; Xu, Hai


    Integrative and conjugative elements (ICEs) are self-transmissible chromosomal mobile elements that play significant roles in the dissemination of antimicrobial resistance genes. Identification of the structures and functions of ICEs, particularly those in pathogens, improves understanding of the dissemination of antimicrobial resistance. This study identified new members of the sulfamethoxazole-trimethoprim (SXT)/R391 family of ICEs that could confer multi-drug resistance in the opportunistic pathogen Proteus mirabilis, characterized their genetic structures, and explored their evolutionary connection with other members of this family of ICEs. Three new members of the SXT/R391 family of ICEs were detected in six of 77 P. mirabilis strains isolated in China: ICEPmiChn2 (one strain), ICEPmiChn3 (one strain) and ICEPmiChn4 (three strains). All three new ICEs harbour antimicrobial resistance genes from diverse origins, suggesting their capability in acquiring foreign genes and serving as important carriers for antimicrobial resistance genes. Structural analysis showed that ICEPmiChn3 is a particularly interesting and unique ICE that has lost core genes involved in conjugation, and could not transfer to other cells via conjugation. This finding confirmed the key roles of these missing genes in conjugation. Further phylogenetic analysis suggested that ICEs in geographically close strains are also connected evolutionarily, and ICEPmiChn3 lost its conjugation cassette from a former mobile ICE. The identification and characterization of the three new members of the SXT/R391 family of ICEs in this work leads to suggestions of core ICE genes essential for conjugation, and extends understanding on the structures of ICEs, evolutionary relationships between ICEs, and the antimicrobial resistance mechanisms of P. mirabilis.

  12. Identification of ISMyo2, a novel insertion sequence element of IS21 family and its diagnostic potential for detection of Mycobacterium yongonense.

    Kim, Byoung-Jun; Kim, Kijeong; Kim, Bo-Ram; Kook, Yoon-Hoh; Kim, Bum-Joon


    Mycobacterium yongonense, as a novel member of the M. avium complex (MAC), was recently reported to be isolated from human specimens in South Korea and Italy. Due to its close relatedness to other MAC members, particularly M. intracellulare in taxonomic aspects, the development of a novel diagnostic method for its specific detection is necessary for clinical or epidemiologic purposes. Using the Mycobacterium yongonense genome information, we have identified a novel IS-element, ISMyo2. Targeting the ISMyo2 sequence, we developed a real-time PCR method and applied the technique to Mycobacterial genomic DNA. To identify proper nucleic acid targets for the diagnosis, comparisons of all insertion sequence (IS) elements of 3 M. intracellulare and 3 M. yongonense strains, whose complete genome sequences we reported recently, led to the selection of a novel target gene, the M. yongonense-specific IS element, ISMyo2 (2,387 bp), belonging to the IS21 family. Next, we developed a real-time PCR method using SYBR green I for M. yongonense-specific detection targeting ISMyo2, producing a 338-bp amplicon. When this assay was applied to 28 Mycobacterium reference strains and 63 MAC clinical isolates, it produced amplicons in only the 6 M. yongonense strains, showing a sensitivity of 100 fg of genomic DNA, suggesting its feasibility as a diagnostic method for M. yongonense strains. We identified a novel ISMyo2 IS element belonging to the IS21 family specific to M. yongonense strains via genome analysis, and a real-time PCR method based on its sequences was developed.

  13. Identification of Relationships Between Patients Through Elements in a Data Warehouse Using the Familial, Associational, and Incidental Relationship (FAIR) Initiative: A Pilot Study.

    English, Thomas M; Kinney, Rebecca L; Davis, Michael J; Kamberi, Ariana; Chan, Wayne; Sadasivam, Rajani S; Houston, Thomas K


    Over the last several years there has been widespread development of medical data warehouses. Current data warehouses focus on individual cases, but lack the ability to identify family members that could be used for dyadic or familial research. Currently, the patient's family history in the medical record is the only documentation we have to understand the health status and social habits of their family members. Identifying familial linkages in a phenotypic data warehouse can be valuable in cohort identification and in beginning to understand the interactions of diseases among families. The goal of the Familial, Associational, & Incidental Relationships (FAIR) initiative is to identify an index set of patients' relationships through elements in a data warehouse. Using a test set of 500 children, we measured the sensitivity and specificity of available linkage algorithm identifiers (eg, insurance identification numbers and phone numbers) and validated this tool/algorithm through a manual chart audit. Of all the children, 52.4% (262/500) were male, and the mean age of the cohort was 8 years old (SD 5). Of the children, 51.6% (258/500) were identified as white in race. The identifiers used for FAIR were available for the majority of patients: insurance number (483/500, 96.6%), phone number (500/500, 100%), and address (497/500, 99.4%). When utilizing the FAIR tool and various combinations of identifiers, sensitivity ranged from 15.5% (62/401) to 83.8% (336/401), and specificity from 72% (71/99) to 100% (99/99). The preferred method was matching patients using insurance or phone number, which had a sensitivity of 72.1% (289/401) and a specificity of 94% (93/99). Using the Informatics for Integrating Biology and the Bedside (i2b2) warehouse infrastructure, we have now developed a Web app that facilitates FAIR for any index population. FAIR is a valuable research and clinical resource that extends the capabilities of existing data warehouses and lays the groundwork for

  14. Assessment of the Level of GABA and Some Trace Elements in Blood in Children who Suffer from Familial Febrile Convulsions

    Osama N. Salah


    Full Text Available Febrile seizure is one of the most common neurological problems during childhood. The etiology and pathogenesis of febrile seizure remain unknown. However, several factors such as vitamin B6 deficiency, electrolyte disturbances, and reduction in serum zinc, selenium, magnesium levels, and low gamma - aminobutyric acid (GABA levels are thought to play a role in the pathogenesis of febrile seizure. The present study included twenty children from 10 families, 11 were male and 9 were female. Each family has at least 2 members with a history of febrile convulsion. All cases were subjected to the following: Determination of serum levels of copper, zinc, magnesium, selenium level in serum, and plasma level of γ-aminobytaric acid (GABA. Serum levels of selenium and GABA were statistically significantly low in comparison with controls. Serum copper was statistically significantly higher in cases than controls, while serum zinc showed no significant changes in the cases of febrile convulsion compared with the control group. The mean Zn level in the serum of febrile convulsion was found to be at lower level than in the control group. The serum magnesium was significantly low in cases than controls. The logistic regression model in our study shows that Selenium and Magnesium have protective effects, while Copper has causative effect.

  15. Molecular and phylogenetic characterization of the sieve element occlusion gene family in Fabaceae and non-Fabaceae plants.

    Rüping, Boris; Ernst, Antonia M; Jekat, Stephan B; Nordzieke, Steffen; Reineke, Anna R; Müller, Boje; Bornberg-Bauer, Erich; Prüfer, Dirk; Noll, Gundula A


    The phloem of dicotyledonous plants contains specialized P-proteins (phloem proteins) that accumulate during sieve element differentiation and remain parietally associated with the cisternae of the endoplasmic reticulum in mature sieve elements. Wounding causes P-protein filaments to accumulate at the sieve plates and block the translocation of photosynthate. Specialized, spindle-shaped P-proteins known as forisomes that undergo reversible calcium-dependent conformational changes have evolved exclusively in the Fabaceae. Recently, the molecular characterization of three genes encoding forisome components in the model legume Medicago truncatula (MtSEO1, MtSEO2 and MtSEO3; SEO = sieve element occlusion) was reported, but little is known about the molecular characteristics of P-proteins in non-Fabaceae. We performed a comprehensive genome-wide comparative analysis by screening the M. truncatula, Glycine max, Arabidopsis thaliana, Vitis vinifera and Solanum phureja genomes, and a Malus domestica EST library for homologs of MtSEO1, MtSEO2 and MtSEO3 and identified numerous novel SEO genes in Fabaceae and even non-Fabaceae plants, which do not possess forisomes. Even in Fabaceae some SEO genes appear to not encode forisome components. All SEO genes have a similar exon-intron structure and are expressed predominantly in the phloem. Phylogenetic analysis revealed the presence of several subgroups with Fabaceae-specific subgroups containing all of the known as well as newly identified forisome component proteins. We constructed Hidden Markov Models that identified three conserved protein domains, which characterize SEO proteins when present in combination. In addition, one common and three subgroup specific protein motifs were found in the amino acid sequences of SEO proteins. SEO genes are organized in genomic clusters and the conserved synteny allowed us to identify several M. truncatula vs G. max orthologs as well as paralogs within the G. max genome. The unexpected

  16. Short interspersed nuclear elements (SINEs) are abundant in Solanaceae and have a family-specific impact on gene structure and genome organization.

    Seibt, Kathrin M; Wenke, Torsten; Muders, Katja; Truberg, Bernd; Schmidt, Thomas


    Short interspersed nuclear elements (SINEs) are highly abundant non-autonomous retrotransposons that are widespread in plants. They are short in size, non-coding, show high sequence diversity, and are therefore mostly not or not correctly annotated in plant genome sequences. Hence, comparative studies on genomic SINE populations are rare. To explore the structural organization and impact of SINEs, we comparatively investigated the genome sequences of the Solanaceae species potato (Solanum tuberosum), tomato (Solanum lycopersicum), wild tomato (Solanum pennellii), and two pepper cultivars (Capsicum annuum). Based on 8.5 Gbp sequence data, we annotated 82 983 SINE copies belonging to 10 families and subfamilies on a base pair level. Solanaceae SINEs are dispersed over all chromosomes with enrichments in distal regions. Depending on the genome assemblies and gene predictions, 30% of all SINE copies are associated with genes, particularly frequent in introns and untranslated regions (UTRs). The close association with genes is family specific. More than 10% of all genes annotated in the Solanaceae species investigated contain at least one SINE insertion, and we found genes harbouring up to 16 SINE copies. We demonstrate the involvement of SINEs in gene and genome evolution including the donation of splice sites, start and stop codons and exons to genes, enlargement of introns and UTRs, generation of tandem-like duplications and transduction of adjacent sequence regions. © 2016 The Authors The Plant Journal © 2016 John Wiley & Sons Ltd.

  17. Evolutionary Dynamics of 5S rDNA and Recurrent Association of Transposable Elements in Electric Fish of the Family Gymnotidae (Gymnotiformes): The Case of Gymnotus mamiraua.

    da Silva, Maelin; Barbosa, Patricia; Artoni, Roberto F; Feldberg, Eliana


    Gymnotidae is a family of electric fish endemic to the Neotropics consisting of 2 genera: Electrophorus and Gymnotus. The genus Gymnotus is widely distributed and is found in all of the major Brazilian river systems. Physical and molecular mapping data for the ribosomal DNA (rDNA) in this genus are still scarce, with its chromosomal location known in only 11 species. As other species of Gymnotus with 2n = 54 chromosomes from the Paraná-Paraguay basin, G. mamiraua was found to have a large number of 5S rDNA sites. Isolation and cloning of the 5S rDNA sequences from G. mamiraua identified a fragment of a transposable element similar to the Tc1/mariner transposon associated with a non-transcribed spacer. Double fluorescence in situ hybridization analysis of this element and the 5S rDNA showed that they were colocalized on several chromosomes, in addition to acting as nonsyntenic markers on others. Our data show the association between these sequences and suggest that the Tc1 retrotransposon may be the agent that drives the spread of these 5S rDNA-like sequences in the G. mamiraua genome. © 2016 S.

  18. S-phase checkpoint elements of the E2F-1 family increase radiosensitivity in fibrosarcoma cells lacking p53

    Bodis, Stephan; Pruschy, Martin; Wirbelauer, Christiane; Glanzmann, Christoph; Krek, Wilhelm


    'null' fibrosarcoma cells with E2F-1 wild-type revealed a synergistic effect at 2 and 5 Gy. The cytotoxic effect of E2F-1 mutants lacking the cyclin-A binding domain in these p53 'null' tumor cells combined with ionizing RT was at least additive. Ionizing RT alone induces massive apoptosis only in the radiosensitive p53 wild-type tumor cells in vitro and in vivo after transplantation into nude mice. The cell death mechanisms of E2F-1 wt and the E2F-1 mt alone and in combination with RT in p53 'null' tumor cells is currently investigated. Conclusion: -S-phase checkpoints elements can increase radiosensitivity in presence and absence of p53. - The cytotoxic effect of a specific E2F-1 mutant lacking the cyclin-A-binding domain is much higher and less p53 dependent compared to the cytotoxic effect of E2F-1 wild-type

  19. Identification and characterization of a new multigene family in the human MHC: A candidate autoimmune disease susceptibility element (3.8-1)

    Harris, J.M.; Venditti, C.P.; Chorney, M.J. [Pennsylvania State Univ. College of Medicine, Hershey, PA (United States)


    An association between idiopathic hemochromatosis (HFE) and the HLA-A3 locus has been previously well-established. In an attempt to identify potential HFE candidate genes, a genomic DNA fragment distal to the HLA-A9 breakpoint was used to screen a B cell cDNA library; a member (3.8-1) of a new multigene family, composed of five distinct genomic cross-reactive fragments, was identified. Clone 3.8-1 represents the 3{prime} end of 9.6 kb transcript which is expressed in multiple tissues including the spleen, thymus, lung and kidney. Sequencing and genome database analysis indicate that 3.8-1 is unique, with no homology to any known entries. The genomic residence of 3-8.1, defined by polymorphism analysis and physical mapping using YAC clones, appears to be absent from the genomes of higher primates, although four other cross-reactivities are maintained. The absence of this gene as well as other probes which map in the TNF to HLA-B interval, suggest that this portion of the human HMC, located between the Class I and Class III regions, arose in humans as the result of a post-speciation insertional event. The large size of the 3.8-1 gene and the possible categorization of 3.8-1 as a human-specific gene are significant given the genetic data that place an autoimmune susceptibility element for IDDM and myasthenia gravis in the precise region where this gene resides. In an attempt to isolate the 5{prime} end of this large transcript, we have constructed a cosmid contig which encompasses the genomic locus of this gene and are progressively isolating coding sequences by exon trapping.

    All members of the IS1248 family residing in the genome of Paracoccus denitrificans have been isolated by using a set of insertion sequence entrapment vectors. The family consists of five closely related members that integrate the entrapment vectors at distinct sites. One of these, IS1248b, was

  1. Element-topology-independent preconditioners for parallel finite element computations

    Park, K. C.; Alexander, Scott


    A family of preconditioners for the solution of finite element equations are presented, which are element-topology independent and thus can be applicable to element order-free parallel computations. A key feature of the present preconditioners is the repeated use of element connectivity matrices and their left and right inverses. The properties and performance of the present preconditioners are demonstrated via beam and two-dimensional finite element matrices for implicit time integration computations.

  3. Theoretical elements for a historical approach to the family and its relations of violence during the transition between the XXth and XXIst centuries

    Bárbara Yadira García Sánchez


    Full Text Available The objective of this article is to relect upon the history of the ield of contemporary family and its changes from the revolution of youth in 1960s until the irst decade of the XXIst century. This historical approach is linked to the study of relations of violence inside the family context. The implementation of certain theoretical and methodological concepts allowed us to establish a contrast between several time periods, starting from the present and going back to situations of the past, following the track of micro social conlicts expressed in violence toward parental igures, as well as in violence between siblings, all of which are analyzed as typologies of what has been called domestic violence. The theoretical relection is supported by some approaches of Pierre Bourdieu regarding the reproduction of symbolic violence, and more speciically, the strategies of its reproduction in the ield of family. We emphasize on the strategies of symbolic, ethicaland educational inversion. The data used to support this article is taken from the database of two research projects on school violence in Bogota between 2009 and 2015.

  6. Structural Analysis of PTM Hotspots (SAPH-ire)--A Quantitative Informatics Method Enabling the Discovery of Novel Regulatory Elements in Protein Families.

    Dewhurst, Henry M; Choudhury, Shilpa; Torres, Matthew P


    Predicting the biological function potential of post-translational modifications (PTMs) is becoming increasingly important in light of the exponential increase in available PTM data from high-throughput proteomics. We developed structural analysis of PTM hotspots (SAPH-ire)--a quantitative PTM ranking method that integrates experimental PTM observations, sequence conservation, protein structure, and interaction data to allow rank order comparisons within or between protein families. Here, we applied SAPH-ire to the study of PTMs in diverse G protein families, a conserved and ubiquitous class of proteins essential for maintenance of intracellular structure (tubulins) and signal transduction (large and small Ras-like G proteins). A total of 1728 experimentally verified PTMs from eight unique G protein families were clustered into 451 unique hotspots, 51 of which have a known and cited biological function or response. Using customized software, the hotspots were analyzed in the context of 598 unique protein structures. By comparing distributions of hotspots with known versus unknown function, we show that SAPH-ire analysis is predictive for PTM biological function. Notably, SAPH-ire revealed high-ranking hotspots for which a functional impact has not yet been determined, including phosphorylation hotspots in the N-terminal tails of G protein gamma subunits--conserved protein structures never before reported as regulators of G protein coupled receptor signaling. To validate this prediction we used the yeast model system for G protein coupled receptor signaling, revealing that gamma subunit-N-terminal tail phosphorylation is activated in response to G protein coupled receptor stimulation and regulates protein stability in vivo. These results demonstrate the utility of integrating protein structural and sequence features into PTM prioritization schemes that can improve the analysis and functional power of modification-specific proteomics data. © 2015 by The American

  9. Galvanic element. Galvanisches Element

    Sprengel, D.; Haelbig, H.


    The invention concerns a gas-tight sealed accumulator with positive and negative electrode plates and an auxillary electrode electroconductively bound to the latter for suppressing oxygen pressure. The auxillary electrode is an intermediate film electrode. The film catalysing oxygen reduction is hydrophilic in character and the other film is hydrophobic. A double coated foil has proved to be advantageous, the hydrophilic film being formed from polymer-bound activated carbon and the hydrophrobic film from porous polytetrafluoroethylene. A metallic network of silver or nickel is rolled into the outer side of the activated carbon film. This auxillary electrode can be used to advantage in all galvanic elements. Even primary cells fall within the scope of application for auxillary electrodes because many of these contain a highly oxidized electrodic material which tends to give off oxygen.

    Full Text Available The amino acid sequence of a family 6 carbohydrate binding module (CtCBM6B from Clostridium thermocellum alpha-L-arabinofuranosidase showed close evolutionary relationship with some other member of family 6 carbohydrate binding modules. The CD spectrum analysis confirmed the secondary structure prediction of CtCBM6B as both showed beta-sheets (44-48% and random coils (52-54% and no alpha-helix. The hydrogen bonding plot of CtCBM6B showed many segments of parallel and anti-parallel beta-strands which was similar to the secondary structure prediction by PSIPRED VIEW. The three dimensional structure of CtCBM6B generated by MODELLER revealed a typical beta-sandwich architecture at its core, characteristic of beta-jelly roll CBM superfamily. The Ramachandran plot analysis by PROCHECK showed that out of 134 residues, 92.9% were in most favoured region, 6.2% in additionally allowed region and only 0.9% in generously allowed region which indicated a stable conformation of 3D model of CtCBM6B. The docking analysis of CtCBM6B for finding putative ligand binding sites showed that it has high binding affinity for arabinobiose, beta-L-arabinofuranose and beta-D-xylopyranose indicated by lower ligand binding energy (-14.28 kcal mol–1, -12.5 kcal mol–1 and -11.3 kcal mol–1, respectively. CtCBM6B also showed appreciable binding affinity with alpha-D-xylopyranose (–10.8 kcal mol–1, beta-L-arabinopyranose (–10.2 kcal mol-1, alpha-L-arabinopyranose (–10.0 kcal mol–1 and alpha-L-arabinofuranose (–8.75 kcal mol–1. The results indicated that CtCBM6B has high potential for binding arabinan, xylans and substituted xylans.

  11. Retroposition of the AFC family of SINEs (short interspersed repetitive elements) before and during the adaptive radiation of cichlid fishes in Lake Malawi and related inferences about phylogeny.

    Takahashi, K; Nishida, M; Yuma, M; Okada, N


    Lake Malawi is home to more than 450 species of endemic cichlids, which provide a spectacular example of adaptive radiation. To clarify the phylogenetic relationships among these fish, we examined the presence and absence of SINEs (short interspersed repetitive elements) at orthologous loci. We identified six loci at which a SINE sequence had apparently been specifically inserted by retroposition in the common ancestor of all the investigated species of endemic cichlids in Lake Malawi. At another locus, unique sharing of a SINE sequence was evident among all the investigated species of endemic non-Mbuna cichlids with the exception of Rhamphochromis sp. The relationships were in good agreement with those deduced in previous studies with various different markers, demonstrating that the SINE method is useful for the elucidation of phylogenetic relationships among cichlids in Lake Malawi. We also characterized a locus that exhibited transspecies polymorphism with respect to the presence or absence of the SINE sequence among non-Mbuna species. This result suggests that incomplete lineage sorting and/or interspecific hybridization might have occurred or be occurring among the species in this group, which might potentially cause misinterpretation of phylogenetic data, in particular when a single-locus marker, such as a sequence in the mitochondrial DNA, is used for analysis.

  12. Cooperation with the charges’ families as a component of functionality of re-socialization institutions for minors [Współpraca z rodzinami wychowanków jako element funkcjonalności instytucji resocjalizacyjnej dla nieletnich

    Barbara JEZIERSKA


    Full Text Available Efficient functioning of a re-socialization institution is a condition of its growth and key factor of appropriate course of the community life that within its structure. Its efficiency relies on explicitly, clearly acknowledged objectives, its internal organization and division of workload as well as the independence of the professional tasks from the personal interests of the staff. Moreover, it tackles the conformity of the staff aspirations with aims and assignments for the accomplishment of which such a structure has been established, entailing high internal integrity, productive cooperation with other facilities and the external environment. It enables the achievement of the projected and socially desired outcomes as well as the accomplishment of common goals upon arrangements of various activities. Cooperation with the family environment of the charges constitutes a key element of the functionality of every re-socialization institution. It must be remembered that parents of the juvenile delinquents manifest features disabling the appropriate course of the upbringing, which consequently can lead to the children’s criminogenic lifestyle. Such features concern structural properties of the families, qualities related to the emotional attitude to their child, parental competences and last but not least – upbringing methods. Non-structural features can be subject to modification in given circumstances. Nonetheless, it is a challenging task particularly when institutions do not participate in the process of family support. Inclusion of the charges’ parents in the process of its correctional activities can condition the quality of educational measures accomplished within, becoming a key indicator of a rational organization and correction of behavior, reforming socially maladjusted behaviors of children and teenagers.

  13. The endogenous retroviral locus ERVWE1 is a bona fide gene involved in hominoid placental physiology

    Mallet, François; Bouton, Olivier; Prudhomme, Sarah; Cheynet, Valérie; Oriol, Guy; Bonnaud, Bertrand; Lucotte, Gérard; Duret, Laurent; Mandrand, Bernard


    The definitive demonstration of a role for a recently acquired gene is a difficult task, requiring exhaustive genetic investigations and functional analysis. The situation is indeed much more complicated when facing multicopy gene families, because most or portions of the gene are conserved among the hundred copies of the family. This is the case for the ERVWE1 locus of the human endogenous retrovirus W family (HERV-W), which encodes an envelope glycoprotein (syncytin) likely involved in trophoblast differentiation. Here we describe, in 155 individuals, the positional conservation of this locus and the preservation of the envelope ORF. Sequencing of the critical elements of the ERVWE1 provirus showed a striking conservation among the 48 alleles of 24 individuals, including the LTR elements involved in the transcriptional machinery, the splice sites involved in the maturation of subgenomic Env mRNA, and the Env ORF. The functionality and tissue specificity of the 5′ LTR were demonstrated, as well as the fusogenic activity of the envelope polymorphic variants. Such functions were also shown to be preserved in the orthologous loci isolated from chimpanzee, gorilla, orangutan, and gibbon. This functional preservation among humans and during evolution strongly argued for the involvement of this recently acquired retroviral envelope glycoprotein in hominoid placental physiology.

  16. Comparative Methylation of ERVWE1/Syncytin-1 and Other Human Endogenous Retrovirus LTRs in Placenta Tissues

    Gimenez, Juliette; Montgiraud, Cécile; Oriol, Guy; Pichon, Jean-Philippe; Ruel, Karine; Tsatsaris, Vassilis; Gerbaud, Pascale; Frendo, Jean-Louis; Evain-Brion, Danièle; Mallet, François


    Human endogenous retroviruses (HERVs) are globally silent in somatic cells. However, some HERVs display high transcription in physiological conditions. In particular, ERVWE1, ERVFRDE1 and ERV3, three proviruses of distinct families, are highly transcribed in placenta and produce envelope proteins associated with placenta development. As silencing of repeated elements is thought to occur mainly by DNA methylation, we compared the methylation of ERVWE1 and related HERVs to appreciate whether HERV methylation relies upon the family, the integration site, the tissue, the long terminal repeat (LTR) function or the associated gene function. CpG methylation of HERV-W LTRs in placenta-associated tissues was heterogeneous but a joint epigenetic control was found for ERVWE1 5′LTR and its juxtaposed enhancer, a mammalian apparent LTR retrotransposon. Additionally, ERVWE1, ERVFRDE1 and ERV3 5′LTRs were all essentially hypomethylated in cytotrophoblasts during pregnancy, but showed distinct and stage-dependent methylation profiles. In non-cytotrophoblastic cells, they also exhibited different methylation profiles, compatible with their respective transcriptional activities. Comparative analyses of transcriptional activity and LTR methylation in cell lines further sustained a role for methylation in the control of functional LTRs. These results suggest that HERV methylation might not be family related but copy-specific, and related to the LTR function and the tissue. In particular, ERVWE1 and ERV3 could be developmentally epigenetically regulated HERVs. PMID:19561344

    To control Peltier elements, temperature controller was used. I used TEC-1091 that was manufactured my Meerstetter Engineering. To gain control with the temperature controller, software had to be intalled on a controlling PC. There were different modes to control the Peltier: Tempererature controller to control temperature, Static current/voltage to control voltage and current and LIVE ON/OFF to auto-tune the controller respectively to the system. Also, since near the collision pipe there is much radiation, radiation-proof Peltier elements have to be used. To gain the best results, I had to find the most efficient Peltier elements and try to get their cold side to -40 degrees Celsius.

  9. Expression and activation by Epstein Barr virus of human endogenous retroviruses-W in blood cells and astrocytes: inference for multiple sclerosis.

    Giuseppe Mameli

    Full Text Available BACKGROUND: Proposed co-factors triggering the pathogenesis of multiple sclerosis (MS are the Epstein Barr virus (EBV, and the potentially neuropathogenic MSRV (MS-associated retrovirus and syncytin-1, of the W family of human endogenous retroviruses. METHODOLOGY/PRINCIPAL FINDINGS: In search of links, the expression of HERV-W/MSRV/syncytin-1, with/without exposure to EBV or to EBV glycoprotein350 (EBVgp350, was studied on peripheral blood mononuclear cells (PBMC from healthy volunteers and MS patients, and on astrocytes, by discriminatory env-specific RT-PCR assays, and by flow cytometry. Basal expression of HERV-W/MSRV/syncytin-1 occurs in astrocytes and in monocytes, NK, and B, but not in T cells. This uneven expression is amplified in untreated MS patients, and dramatically reduced during therapy. In astrocytes, EBVgp350 stimulates the expression of HERV-W/MSRV/syncytin-1, with requirement of the NF-κB pathway. In EBVgp350-treated PBMC, MSRVenv and syncytin-1 transcription is activated in B cells and monocytes, but not in T cells, nor in the highly expressing NK cells. The latter cells, but not the T cells, are activated by proinflammatory cytokines. CONCLUSIONS/SIGNIFICANCE: In vitro EBV activates the potentially immunopathogenic and neuropathogenic HERV-W/MSRV/syncytin-1, in cells deriving from blood and brain. In vivo, pathogenic outcomes would depend on abnormal situations, as in late EBV primary infection, that is often symptomatic, or/and in the presence of particular host genetic backgrounds. In the blood, HERV-Wenv activation might induce immunopathogenic phenomena linked to its superantigenic properties. In the brain, toxic mechanisms against oligodendrocytes could be established, inducing inflammation, demyelination and axonal damage. Local stimulation by proinflammatory cytokines and other factors might activate further HERV-Ws, contributing to the neuropathogenity. In MS pathogenesis, a possible model could include EBV as

    Abbott, T.I.; Jones, C.G.


    Radiographic elements are disclosed comprised of first and second silver halide emulsion layers separated by an interposed support capable of transmitting radiation to which the second image portion is responsive. At least the first imaging portion contains a silver halide emulsion in which thin tubular silver halide grains of intermediate aspect ratios (from 5:1 to 8:1) are present. Spectral sensitizing dye is adsorbed to the surface of the tubular grains. Increased photographic speeds can be realized at comparable levels of crossover. (author)

  12. Superheavy elements

    Hofmann, S


    The outstanding aim of experimental investigations of heavy nuclei is the exploration of spherical 'SuperHeavy Elements' (SHEs). On the basis of the nuclear shell model, the next double magic shell-closure beyond sup 2 sup 0 sup 8 Pb is predicted at proton numbers between Z=114 and 126 and at neutron number N=184. All experimental efforts aiming at identifying SHEs (Z>=114) were negative so far. A highly sensitive search experiment was performed in November-December 1995 at SHIP. The isotope sup 2 sup 9 sup 0 116 produced by 'radiative capture' was searched for in the course of a 33 days irradiation of a sup 2 sup 0 sup 8 Pb target with sup 8 sup 2 Se projectiles, however, only cross-section limits were measured. Positive results were obtained in experiments searching for elements from 110 to 112 using cold fusion and the 1n evaporation channel. The produced isotopes were unambiguously identified by means of alpha-alpha correlations. Not fission, but alpha emission is the dominant decay mode. The measurement ...

    The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

  15. Fuel element

    Hirose, Yasuo.


    Purpose: To increase the plenum space in a fuel element used for a liquid metal cooled reactor. Constitution: A fuel pellet is secured at one end with an end plug and at the other with a coil spring in a tubular container. A mechanism for fixing the coil spring composed of a tubular unit is mounted by friction with the inner surface of the tubular container. Accordingly, the recoiling force of the coil spring can be retained by fixing mechanism with a small volume, and since a large amount of plenum space can be obtained, the internal pressure rise in the cladding tube can be suppressed even if large quantities of fission products are discharged.

  20. Current status of family health in Mexico

    Apolinar Membrillo Luna


    Full Text Available Family Health (FH has three main elements: individual health, life material conditions and family functioning. Its main actors are the individual, the family and society. A common framework is the basis of FH, as each one of these elements is extremely important. Currently, in Mexico two aspects are considered: epidemiological studies and those inherent to the family medicine specialty. That latter has a residency and an integrated specialty curriculum, as well as certification from the corresponding board. All of this allows us to apply the HF approach to each and every family and individual that is cared for.

  1. Jamaican families.

    Miner, Dianne Cooney


    The study of the family in the Caribbean originated with European scholars who assumed the universality of the patriarchal nuclear family and the primacy of this structure to the healthy functioning of society. Matrifocal Caribbean families thus were seen as chaotic and disorganized and inadequate to perform the essential tasks of the social system. This article provides a more current discussion of the Jamaican family. It argues that its structure is the result of the agency and adaptation of its members and not the root cause of the increasing marginalization of peoples in the developing world. The article focuses on families living in poverty and how the family structure supports essential family functions, adaptations, and survival.

  10. Genome-Wide Analyses of the NAC Transcription Factor Gene Family in Pepper (Capsicum annuum L.: Chromosome Location, Phylogeny, Structure, Expression Patterns, Cis-Elements in the Promoter, and Interaction Network

    Weiping Diao


    Full Text Available The NAM, ATAF1/2, and CUC2 (NAC transcription factors form a large plant-specific gene family, which is involved in the regulation of tissue development in response to biotic and abiotic stress. To date, there have been no comprehensive studies investigating chromosomal location, gene structure, gene phylogeny, conserved motifs, or gene expression of NAC in pepper (Capsicum annuum L.. The recent release of the complete genome sequence of pepper allowed us to perform a genome-wide investigation of Capsicum annuum L. NAC (CaNAC proteins. In the present study, a comprehensive analysis of the CaNAC gene family in pepper was performed, and a total of 104 CaNAC genes were identified. Genome mapping analysis revealed that CaNAC genes were enriched on four chromosomes (chromosomes 1, 2, 3, and 6. In addition, phylogenetic analysis of the NAC domains from pepper, potato, Arabidopsis, and rice showed that CaNAC genes could be clustered into three groups (I, II, and III. Group III, which contained 24 CaNAC genes, was exclusive to the Solanaceae plant family. Gene structure and protein motif analyses showed that these genes were relatively conserved within each subgroup. The number of introns in CaNAC genes varied from 0 to 8, with 83 (78.9% of CaNAC genes containing two or less introns. Promoter analysis confirmed that CaNAC genes are involved in pepper growth, development, and biotic or abiotic stress responses. Further, the expression of 22 selected CaNAC genes in response to seven different biotic and abiotic stresses [salt, heat shock, drought, Phytophthora capsici, abscisic acid, salicylic acid (SA, and methyl jasmonate (MeJA] was evaluated by quantitative RT-PCR to determine their stress-related expression patterns. Several putative stress-responsive CaNAC genes, including CaNAC72 and CaNAC27, which are orthologs of the known stress-responsive Arabidopsis gene ANAC055 and potato gene StNAC30, respectively, were highly regulated by treatment with

  17. Family welfare.

    Sinha, N K


    Between 1901-1921, India gained 12.9 million people because mortality remained high. The death rate fell between 1921-1951, but birth rates remained the same. Therefore 110 million people were added--2 times the population increase between 1891-1921. Between 1951-1981, the population increased to 324 million. Socioeconomic development was responsible for most of the downward trend in the birth rate during the 20th century. Even though large families were the norm in early India, religious leaders encouraged small family size. The 1st government family planning clinics in the world opened in Mysore and Bangalore in 1930. Right before Independence, the Bhore Committee made recommendations to reduce population growth such as increasing the age of marriage for girls. Since 1951 there has been a change in measures and policies geared towards population growth with each of the 7 5-Year Plans because policy makers applied what they learned from each previous plan. The 1st 5-Year Plan emphasized the need to understand what factors contribute to population growth. It also integrated family planning services into health services of hospitals and health centers. The government was over zealous in its implementation of the sterilization program (2nd 5-Year Plan, 1956-1961), however, which hurt family planning programs for many years. As of early 1992, sterilization, especially tubectomy, remained the most popular family planning method, however. The 7th 5-Year Plan changed its target of reaching a Net Reproductive Rate of 1 by 2001 to 2006-2011. It set a goal of 100% immunization coverage by 1990 but it did not occur. In 1986, the Ministry of Health and Family Welfare planned to make free contraceptives available in urban and rural areas and to involve voluntary organizations. The government needs to instill measures to increase women's status, women's literacy, and age of marriage as well as to eliminate poverty, ensure old age security, and ensure child survival and

  18. Discrete Element Modeling

    Morris, J; Johnson, S


    The Distinct Element Method (also frequently referred to as the Discrete Element Method) (DEM) is a Lagrangian numerical technique where the computational domain consists of discrete solid elements which interact via compliant contacts. This can be contrasted with Finite Element Methods where the computational domain is assumed to represent a continuum (although many modern implementations of the FEM can accommodate some Distinct Element capabilities). Often the terms Discrete Element Method and Distinct Element Method are used interchangeably in the literature, although Cundall and Hart (1992) suggested that Discrete Element Methods should be a more inclusive term covering Distinct Element Methods, Displacement Discontinuity Analysis and Modal Methods. In this work, DEM specifically refers to the Distinct Element Method, where the discrete elements interact via compliant contacts, in contrast with Displacement Discontinuity Analysis where the contacts are rigid and all compliance is taken up by the adjacent intact material.

  19. Familial macrocephaly

    Tatsuno, Masaru; Hayashi, Michiko; Iwamoto, Hiroko


    We reported 63 macrocephalic children with special emphasis on 16 cases with familial macrocephaly. Of the 16 children with familial macrocephaly, 13 were boys. Foureen parents (13 fathers and 1 mother) had head sizes above 98th percentile. Three of 5 brothers and 5 of 8 sisters also had large heads. The head circumference at birth was known for 14 of the children and it was above the 98th percentile in 7 patients. Subsequent evaluations have shown the head size of these children to be following a normal growth curve. Some of the children were hypotonic as infants, but their development was generally normal. CT scans usually clearly distinguished these children from those with hydorocephalus. The familial macrocephalic children had ventricular measurements which were within the normal range, but absolute measurements of the ventricular size may be misleading, because the CT appearance was of mildly dilated ventricles in half of them.

  1. Human endogenous retroviruses and multiple sclerosis: innocent bystanders or disease determinants?

    Antony, Joseph M; Deslauriers, Andre M; Bhat, Rakesh K; Ellestad, Kristofer K; Power, Christopher


    Human endogenous retroviruses (HERVs) constitute 5-8% of human genomic DNA and are replication incompetent despite expression of individual HERV genes from different chromosomal loci depending on the specific tissue. Several HERV genes have been detected as transcripts and proteins in the central nervous system, frequently in the context of neuroinflammation. The HERV-W family has received substantial attention in large part because of associations with diverse syndromes including multiple sclerosis (MS) and several psychiatric disorders. A HERV-W-related retroelement, multiple sclerosis retrovirus (MSRV), has been reported in MS patients to be both a biomarker as well as an effector of aberrant immune responses. HERV-H and HERV-K have also been implicated in MS and other neurological diseases but await delineation of their contributions to disease. The HERV-W envelope-encoded glycosylated protein, syncytin-1, is encoded by chromosome 7q21 and exhibits increased glial expression within MS lesions. Overexpression of syncytin-1 in glia induces endoplasmic reticulum stress leading to neuroinflammation and the induction of free radicals, which damage proximate cells. Syncytin-1's receptor, ASCT1 is a neutral amino acid transporter expressed on glia and is suppressed in white matter of MS patients. Of interest, antioxidants ameliorate syncytin-1's neuropathogenic effects raising the possibility of using these agents as therapeutics for neuroinflammatory diseases. Given the multiple insertion sites of HERV genes as complete and incomplete open reading frames, together with their differing capacity to be expressed and the complexities of individual HERVs as both disease markers and bioactive effectors, HERV biology is a compelling area for understanding neuropathogenic mechanisms and developing new therapeutic strategies. 2010 Elsevier B.V.

  12. Transposable elements in the Anopheles funestus transcriptome.

    Fernández-Medina, Rita D; Carareto, Claudia M A; Struchiner, Cláudio J; Ribeiro, José M C


    Transposable elements (TEs) are present in most of the eukaryotic genomes and their impact on genome evolution is increasingly recognized. Although there is extensive information on the TEs present in several eukaryotic genomes, less is known about the expression of these elements at the transcriptome level. Here we present a detailed analysis regarding the expression of TEs in Anopheles funestus, the second most important vector of human malaria in Africa. Several transcriptionally active TE families belonging both to Class I and II were identified and characterized. Interestingly, we have identified a full-length putative active element (including the presence of full length TIRs in the genomic sequence) belonging to the hAT superfamily, which presents active members in other insect genomes. This work contributes to a comprehensive understanding of the landscape of transposable elements in A. funestus transcriptome. Our results reveal that TEs are abundant and diverse in the mosquito and that most of the TE families found in the genome are represented in the mosquito transcriptome, a fact that could indicate activity of these elements.The vast diversity of TEs expressed in A. funestus suggests that there is ongoing amplification of several families in this organism.

  13. [Family violence].

    Manoudi, F; Chagh, R; Es-soussi, M; Asri, F; Tazi, I


    Family violence is a serious public health problem, the scale of which is seriously increasing in Morocco. Although it has existed for a long time, we ignore the real characteristics of this plague in our country; our work consisted in an epidemiological approach of family violence in Marrakech during 2006. After elaborating a questionnaire, which allows the study of the demographic and social profile of the families, the study of violence exercised in the family and the evaluation of the depression in the women, we led an inquiry amongst 265 women. Analysis of the results obtained has allowed us to underline the following characteristics: 16.6% of the women in our sample had been physically beaten; the young age is a risk factor; the age range most affected by violence is in women between the ages of 30 and 40 and which represent 39% of the battered women; domestic violence touches all the social, economic and cultural classes: in our study, 63% of the women having undergone violence were housewives, 25% were managers and 3% senior executives; family problems were the most important cause of violence in our study, representing 32.32%. Requests for money was the cause in 11.3% of the cases, and imposed sexual relations were found in 6.8% of the cases; alcoholism is an aggravating factor of family violence; 27.3% of the spouses who assaulted their wives were drunk; 52% of the assaulted women were victims of violence in childhood and 36% had been witness to their father's violence; in 63.6% of the cases of violence, the children were witnesses, and in 25% of the cases the children were victims of violence at the same time as their mothers; 50% of the women victims of violence did not react, while 38.6% left home, and 9.1 filed for divorce. Thirty-two percent of the assaulted woman had been traumatised by the aggression; the association of depression and violence was very high, 343% of the battered women in our study suffered from severe depression.

    Bombyliidae is one of the largest Diptera families with more than 4,500 recognized species worldwide. Their species vary from robust to thin, and may be small to large (2-20mm) and looks like bees or wasps. They also present great variation in color. Adults can often be seen either resting and sunning themselves on trails, rocks or twigs or feeding on flowering plants as they are nectar feeders. All reared bee flies are predators or parasitoids of arthropods. The Colombian fauna of bombyliids comprises at the moment 22 species, and 12 genera, of which, six are endemic species. Nonetheless, this number may be much higher, as Colombia is a megadiverse country and there are not many specimens of this family deposited in collections all over the world.

  15. Asteroid families, dynamics and astrometry

    Williams, J.G.; Gibson, J.


    The proper elements and family assignments for the 1227 Palomar-Leiden Survey asteroids of high quality were tabulated. In addition to the large table, there are also auxiliary tables of Mars crossers and commensurate objects, histograms of the proper element distributions, and a discussion. Probably the most important part of the discussion describes the Mars crossing boundary, how the closest distances of approach to Mars and Jupiter are calculated, and why the observed population of Mars crossers should bombard that planet episodically rather than uniformly. Analytical work was done to derive velocity distributions of family forming events from proper element distributions subject to assumptions which may be appropriate for cratering events. Software was developed for a microcomputer to permit plotting of the proper elements. Three orthogonal views are generated and stereo pairs can be printed when desired. This program was created for the study of asteroid families. The astrometry task is directed toward measuring and reducing positions on faint comets and the minor planets with less common orbits. The observational material is CCD frames taken with the Palomar 1.5 m telescope. Positions of 10 comets and 16 different asteroids were published on the Minor Planet Circulars

  19. Transcriptional activity of transposable elements in coelacanth.

    Forconi, Mariko; Chalopin, Domitille; Barucca, Marco; Biscotti, Maria Assunta; De Moro, Gianluca; Galiana, Delphine; Gerdol, Marco; Pallavicini, Alberto; Canapa, Adriana; Olmo, Ettore; Volff, Jean-Nicolas


    The morphological stasis of coelacanths has long suggested a slow evolutionary rate. General genomic stasis might also imply a decrease of transposable elements activity. To evaluate the potential activity of transposable elements (TEs) in "living fossil" species, transcriptomic data of Latimeria chalumnae and its Indonesian congener Latimeria menadoensis were compared through the RNA-sequencing mapping procedures in three different organs (liver, testis, and muscle). The analysis of coelacanth transcriptomes highlights a significant percentage of transcribed TEs in both species. Major contributors are LINE retrotransposons, especially from the CR1 family. Furthermore, some particular elements such as a LF-SINE and a LINE2 sequences seem to be more expressed than other elements. The amount of TEs expressed in testis suggests possible transposition burst in incoming generations. Moreover, significant amount of TEs in liver and muscle transcriptomes were also observed. Analyses of elements displaying marked organ-specific expression gave us the opportunity to highlight exaptation cases, that is, the recruitment of TEs as new cellular genes, but also to identify a new Latimeria-specific family of Short Interspersed Nuclear Elements called CoeG-SINEs. Overall, transcriptome results do not seem to be in line with a slow-evolving genome with poor TE activity. © 2013 Wiley Periodicals, Inc.

  2. Asteroid families from cratering: Detection and models

    Milani, A.; Cellino, A.; Knežević, Z.; Novaković, B.; Spoto, F.; Paolicchi, P.


    A new asteroid families classification, more efficient in the inclusion of smaller family members, shows how relevant the cratering impacts are on large asteroids. These do not disrupt the target, but just form families with the ejecta from large craters. Of the 12 largest asteroids, 8 have cratering families: number (2), (4), (5), (10), (87), (15), (3), and (31). At least another 7 cratering families can be identified. Of the cratering families identified so far, 7 have >1000 members. This imposes a remarkable change from the focus on fragmentation families of previous classifications. Such a large dataset of asteroids believed to be crater ejecta opens a new challenge: to model the crater and family forming event(s) generating them. The first problem is to identify which cratering families, found by the similarity of proper elements, can be formed at once, with a single collision. We have identified as a likely outcome of multiple collisions the families of (4), (10), (15), and (20). Of the ejecta generated by cratering, only a fraction reaches the escape velocity from the surviving parent body. The distribution of velocities at infinity, giving to the resulting family an initial position and shape in the proper elements space, is highly asymmetric with respect to the parent body. This shape is deformed by the Yarkovsky effect and by the interaction with resonances. All the largest asteroids have been subjected to large cratering events, thus the lack of a family needs to be interpreted. The most interesting case is (1) Ceres, which is not the parent body of the nearby family of (93). Two possible interpretations of the low family forming efficiency are based on either the composition of Ceres with a significant fraction of ice, protected by a thin crust, or with the larger escape velocity of ~500 m/s.

  3. Rare (Earth Elements [score

    Camilo Méndez


    Full Text Available Rare (Earth Elements is a cycle of works for solo piano. The cycle was inspired by James Dillon’s Book of Elements (Vol. I-V. The complete cycle will consist of 14 pieces; one for each selected rare (earth element. The chosen elements are Neodymium, Erbium, Tellurium, Hafnium, Tantalum, Technetium, Indium, Dysprosium, Lanthanium, Cerium, Europium, Terbium, Yttrium and Darmstadtium. These elements were selected due to their special atomic properties that in many cases make them extremely valuable for the development of new technologies, and also because of their scarcity. To date, only 4 works have been completed Yttrium, Technetium, Indium and Tellurium.

  4. Generalized finite elements

    Wachspress, E.


    Triangles and rectangles are the ubiquitous elements in finite element studies. Only these elements admit polynomial basis functions. Rational functions provide a basis for elements having any number of straight and curved sides. Numerical complexities initially associated with rational bases precluded extensive use. Recent analysis has reduced these difficulties and programs have been written to illustrate effectiveness. Although incorporation in major finite element software requires considerable effort, there are advantages in some applications which warrant implementation. An outline of the basic theory and of recent innovations is presented here. (authors)

    History is replete with examples of spectacular ascents of family businesses. Yet there are also numerous accounts of family businesses brought down by bitter feuds among family members, disappointed expectations between generations, and tragic sagas of later generations unable to manage their wealth. A large fraction of businesses throughout the world are organized around families. Why are family firms so prevalent? What are the implications of family control for the governance, financing an...

  6. Elements beyond uranium

    Seaborg, G.T.; Loveland, W.D.


    This book is the 12th volume in a series on transuranium elements. Varied techniques for production of these elements, the methods used in the identification, and the exquisitely refined microchemical techniques required to deal wth samples sometimes involving only a few atoms are described in detail. The chapter on synthesis of the new elements is liberally laced with reminiscences of the proud progenitors as well as the criteria for the discovery of a new chemical element. The authors lament that the superheavy elements (elements in the region of atomic number 114) still elude detection even though their creation should be possible, and some, at least, should survive long enough to be detected. One chapter in the book is devoted to practical applictions of uranium, and the transuranic elements

  10. Computation of Asteroid Proper Elements: Recent Advances

    Knežević, Z.


    The recent advances in computation of asteroid proper elements are briefly reviewed. Although not representing real breakthroughs in computation and stability assessment of proper elements, these advances can still be considered as important improvements offering solutions to some practical problems encountered in the past. The problem of getting unrealistic values of perihelion frequency for very low eccentricity orbits is solved by computing frequencies using the frequency-modified Fourier transform. The synthetic resonant proper elements adjusted to a given secular resonance helped to prove the existence of Astraea asteroid family. The preliminary assessment of stability with time of proper elements computed by means of the analytical theory provides a good indication of their poorer performance with respect to their synthetic counterparts, and advocates in favor of ceasing their regular maintenance; the final decision should, however, be taken on the basis of more comprehensive and reliable direct estimate of their individual and sample average deviations from constancy.

  12. Human endogenous retroviruses in neurologic disease.

    Christensen, Tove


    Endogenous retroviruses are pathogenic - in other species than the human. Disease associations for Human Endogenous RetroViruses (HERVs) are emerging, but so far an unequivocal pathogenetic cause-effect relationship has not been established. A role for HERVs has been proposed in neurological and neuropsychiatric diseases as diverse as multiple sclerosis (MS) and schizophrenia (SCZ). Particularly for MS, many aspects of the activation and involvement of specific HERV families (HERV-H/F and HERV-W/MSRV) have been reported, both for cells in the circulation and in the central nervous system. Notably envelope genes and their gene products (Envs) appear strongly associated with the disease. For SCZ, for ALS, and for HIV-associated dementia (HAD), indications are accumulating for involvement of the HERV-K family, and also HERV-H/F and/or HERV-W. Activation is reasonably a prerequisite for causality as most HERV sequences remain quiescent in non-pathological conditions, so the importance of regulatory pathways and epigenetics involved in regulating HERV activation, derepression, and also involvement of retroviral restriction factors, is emerging. HERV-directed antiretrovirals have potential as novel therapeutic paradigms in neurologic disease, particularly in MS. The possible protective or ameliorative effects of antiretroviral therapy in MS are substantiated by reports that treatment of HIV infection may be associated with a significantly decreased risk of MS. Further studies of HERVs, their role in neurologic diseases, and their potential as therapeutic targets are essential. © 2016 APMIS. Published by John Wiley & Sons Ltd.

  13. Limitless Analytic Elements

    Strack, O. D. L.


    We present equations for new limitless analytic line elements. These elements possess a virtually unlimited number of degrees of freedom. We apply these new limitless analytic elements to head-specified boundaries and to problems with inhomogeneities in hydraulic conductivity. Applications of these new analytic elements to practical problems involving head-specified boundaries require the solution of a very large number of equations. To make the new elements useful in practice, an efficient iterative scheme is required. We present an improved version of the scheme presented by Bandilla et al. (2007), based on the application of Cauchy integrals. The limitless analytic elements are useful when modeling strings of elements, rivers for example, where local conditions are difficult to model, e.g., when a well is close to a river. The solution of such problems is facilitated by increasing the order of the elements to obtain a good solution. This makes it unnecessary to resort to dividing the element in question into many smaller elements to obtain a satisfactory solution.

  15. The solar element

    Kragh, Helge


    of the nineteenth century. In the modest form of a yellow spectral line known as D3, 'helium' was sometimes supposed to exist in the Sun's atmosphere, an idea which is traditionally ascribed to J. Norman Lockyer. Did Lockyer discover helium as a solar element? How was the suggestion received by chemists, physicists...... and astronomers in the period until the spring of 1895, when William Ramsay serendipitously found the gas in uranium minerals? The hypothetical element helium was fairly well known, yet Ramsay's discovery owed little or nothing to Lockyer's solar element. Indeed, for a brief while it was thought that the two...... elements might be different. The complex story of how helium became established as both a solar and terrestrial element involves precise observations as well as airy speculations. It is a story that is unique among the discovery histories of the chemical elements....

  16. The synthetic elements

    Hoffman, D.C.


    Prior to 1940, the heaviest element known was uranium, discovered in 1789. Since that time the elements 93 through 109 have been synthesized and identified and the elements 43, 61, 85, and 87 which were missing form the periodic tables of the 1930's have been discovered. The techniques and problems involved in these discoveries and the placement of the transuranium elements in the periodic table will be discussed. The production and positive identification of elements heavier than Md (Z=101), which have very short half-lives and can only be produced an atom-at-a-time, are very difficult and there have been controversies concerning their discovery. Some of the new methods which have been developed and used in these studies will be described. The prospects for production of still heavier elements will be considered.

  2. Analogs for transuranic elements

    Weimer, W.C.; Laul, J.C.; Kutt, J.C.


    A combined theoretical and experimental approach is being used to estimate the long-term environmental and biogeochemical behaviors of selected transuranic elements. The objective of this research is to estimate the effect that long-term (hundreds of years) environmental weathering has on the behavior of the transuranic elements americium and curium. This is achieved by investigating the actual behavior of naturally occurring rare earth elements, especially neodymium, that serve as transuranic analogs. Determination of the analog element behavior provides data that can be used to estimate the ultimate availability to man of transuranic materials released into the environment

  3. Chemistry of superheavy elements

    Schaedel, M.


    The chemistry of superheavy elements - or transactinides from their position in the Periodic Table - is summarized. After giving an overview over historical developments, nuclear aspects about synthesis of neutron-rich isotopes of these elements, produced in hot-fusion reactions, and their nuclear decay properties are briefly mentioned. Specific requirements to cope with the one-atom-at-a-time situation in automated chemical separations and recent developments in aqueous-phase and gas-phase chemistry are presented. Exciting, current developments, first applications, and future prospects of chemical separations behind physical recoil separators ('pre-separator') are discussed in detail. The status of our current knowledge about the chemistry of rutherfordium (Rf, element 104), dubnium (Db, element 105), seaborgium (Sg, element 106), bohrium (Bh, element 107), hassium (Hs, element 108), copernicium (Cn, element 112), and element 114 is discussed from an experimental point of view. Recent results are emphasized and compared with empirical extrapolations and with fully-relativistic theoretical calculations, especially also under the aspect of the architecture of the Periodic Table.

  4. Strengthening Family Practices for Latino Families.

    Chartier, Karen G; Negroni, Lirio K; Hesselbrock, Michie N


    The study examined the effectiveness of a culturally-adapted Strengthening Families Program (SFP) for Latinos to reduce risks for alcohol and drug use in children. Latino families, predominantly Puerto Rican, with a 9-12 year old child and a parent(s) with a substance abuse problem participated in the study. Pre- and post-tests were conducted with each family. Parental stress, parent-child dysfunctional relations, and child behavior problems were reduced in the families receiving the intervention; family hardiness and family attachment were improved. Findings contribute to the validation of the SFP with Latinos, and can be used to inform social work practice with Puerto Rican families.

  10. Proceedings of transuranium elements



    The identification of the first synthetic elements was established by chemical evidence. Conclusive proof of the synthesis of the first artificial element, technetium, was published in 1937 by Perrier and Segre. An essential aspect of their achievement was the prediction of the chemical properties of element 43, which had been missing from the periodic table and which was expected to have properties similar to those of manganese and rhenium. The discovery of other artificial elements, astatine and francium, was facilitated in 1939-1940 by the prediction of their chemical properties. A little more than 50 years ago, in the spring of 1940, Edwin McMillan and Philip Abelson synthesized element 93, neptunium, and confirmed its uniqueness by chemical means. On August 30, 1940, Glenn Seaborg, Arthur Wahl, and the late Joseph Kennedy began their neutron irradiations of uranium nitrate hexahydrate. A few months later they synthesized element 94, later named plutonium, by observing the alpha particles emitted from uranium oxide targets that had been bombarded with deuterons. Shortly thereafter they proved that is was the second transuranium element by establishing its unique oxidation-reduction behavior. The symposium honored the scientists and engineers whose vision and dedication led to the discovery of the transuranium elements and to the understanding of the influence of 5f electrons on their electronic structure and bonding. This volume represents a record of papers presented at the symposium

  12. Human endogenous retroviruses and chosen disease parameters in morphea

    Dańczak-Pazdrowska, Aleksandra; Szramka-Pawlak, Beata; Żaba, Ryszard; Osmola-Mańkowska, Agnieszka; Silny, Wojciech


    Introduction Morphea (localized scleroderma) is a relatively rare disease characterized by excessive skin fibrosis. Human endogenous retroviruses (HERV) are largely distributed within the human genome with hundreds of thousands of elements. The HERV have been widely studied in autoimmune disorders, yet hardly ever assessed in diseases with a good prognosis such as morphea. Aim In this study we focus on the possible relations between the expression of chosen HERV and factors influencing the pathomechanism of the disease, such as age, sex, titres of anti-nuclear antibodies, as well as duration, activity, and severity of the disease (LoSSI index). Material and methods Real-time polymerase chain reaction (PCR) targeting six HERV sequences of interest were performed on samples derived from peripheral blood mononuclear cells (PBMC) and skin biopsies. Results In PBMC we found a statistically significant negative correlation between HERV-W env expression and LoSSI index (p = 0.01). Additionally, HERV-W env was downregulated in patients with the active form of morphea. In all other cases we found no correlation whatsoever nor statistically significant differences below the p = 0.05 threshold. Conclusions Morphea seems to be an autoimmune disease where the impact of HERV is not so apparent. It seems that probing many patients for the expression of just a few sequences is not as effective as previously expected. For initial studies of HERV in other diseases we recommend high throughput techniques such as HERV-dedicated DNA microarrays or massive parallel sequencing. PMID:28261031

  14. Strategies for improving family engagement during family-centered rounds.

    Kelly, Michelle M; Xie, Anping; Carayon, Pascale; DuBenske, Lori L; Ehlenbach, Mary L; Cox, Elizabeth D


    Family-centered rounds (FCR) are recommended as standard practice in the pediatric inpatient setting; however, limited data exist on best practices promoting family engagement during rounds. To identify strategies to enhance family engagement during FCR using a recognized systems engineering approach. In this qualitative study, stimulated recall interviews using video-recorded rounding sessions were conducted with participants representing the various stakeholders on rounds (15 parents/children and 22 healthcare team [HCT] members) from 4 inpatient services at a children's hospital in Wisconsin. On video review, participants were asked to provide strategies that would increase family engagement on FCR. Qualitative content analysis of interview transcripts was performed in an iterative process. We identified 21 categories of strategies corresponding to 2 themes related to the structure and process of FCR. Strategies related to the structure of FCR were associated with all five recognized work system elements: people (HCT composition), tasks (HCT roles), organization (scheduling of rounds and HCT training), environment (location of rounds and HCT positioning), and tools and technologies (computer use). Strategies related to the FCR process were associated with three rounding phases: before (HCT and family preparation), during (eg, introductions, presentation content, communication style), and after (follow-up) FCR. We identified a range of strategies to enhance family engagement during FCR. These strategies both confirm prior work on the importance of the content and style of communication on rounds and highlight other factors within the hospital work system, like scheduling and computer use, which may affect family engagement in care.

  15. Asteroid families in the Cybele and Hungaria groups

    Vinogradova, T.; Shor, V.


    Asteroid families are fragments of some disrupted parent bodies. Planetary perturbations force the primarily close orbits to evolve. One of the main features of the orbit evolution is the long-period variation of the osculating elements, such as the inclination and eccentricity. Proper elements are computed by elimination of short- and long-period perturbations, and, practically, they do not change with time. Therefore, proper elements are important for family-identification procedures. The techniques of proper-element computation have improved over time. More and more accurate dynamical theories are developed. Contrastingly, in this work, an empirical method is proposed for proper-element calculations. The long-term variations of osculating elements manifest themselves very clearly in the distributions of pairs: inclination and longitude of ascending node; eccentricity and longitude of perihelion in the corresponding planes. Both of these dependencies have a nearly sinusoidal form for most asteroid orbits with regular motion of node and perihelion. If these angular parameters librate, then the sinusoids transform to some closed curve. Hence, it is possible to obtain forced elements, as parameters of curves specified above. The proper elements can be calculated by an elimination of the forced ones. The method allows to obtain the proper elements in any region, if there is a sufficient number of asteroids. This fact and the simplicity of the calculations are advantages of the empirical method. The derived proper elements include the short-period perturbations, but their accuracy is sufficient to search for asteroid families. The special techniques have been developed for the identification of the families, but over a long time large discrepancies took place between the lists of families derived by different authors. As late as 1980, a list of 30 reliable families was formed. And now the list by D. Nesvorny includes about 80 robust families. To date, only two

  17. Discovery of element 112

    Hofmann, S. [GSI, Darmstadt (Germany)


    The new elements 110, 111, and 112 were synthesized and unambiguously identified in experiments at SHIP. Due to strong shell effects the dominant decay mode is not fission, but emission of alpha particles. Theoretical investigations predict that maximum shell effects should exist in nuclei near proton number 114 and neutron number 184. Measurements give hope that isotopes of element 114 close to the island of spherical Superheavy Elements could be produced by fusion reactions using {sup 118}Pb as target. systematic studies of the reaction cross-sections indicate that transfer of nucleons is the important process to initiate the fusion.

  18. Nuclear fuel element

    Grossman, L.N.; Levin, H.A.


    A nuclear fuel element has disposed therein an alloy having the essential components of nickel, titanium and zirconium, and the alloy reacts with water, water vapor and reactive gases at reactor ambient temperatures. The alloy is disposed in the plenum of the fuel element in the form of particles in a hollow gas permeable container having a multiplicity of openings of size smallr than the size of the particles. The container is preferably held in the spring in the plenum of the fuel element. (E.C.B.)

  19. Elemental diffusion in stars

    Michaud, Georges; Montmerle, Thierry


    This paper is dealing with the origin of the elements in the universe. The scheme of nucleosynthesis is kept to explain the stellar generation of helium, carbon, etc... from the initial hydrogen; but a nonlinear theory is then elaborated to account for the anomalous abundances which were observed. The chemical elements would diffuse throughout the outer layers of a star under the action of the opposite forces of gravitation and radiation. This theory, with completing the nucleosynthesis, would contribute to give a consistent scheme of the elemental origin and abundances [fr

  20. Determination of trace elements of Egyptian crops by neutron activation analysis Pt. 3

    Sherif, M.K.; Awadallah, R.M.; Amrallah, A.H.


    Multielemental neutron activation analysis was used for the determination of Al, As, Au, Br, Ca, Cd, Co, Cr, Cu, Fe, La, Mn, Mo, Sb, Se, W and Zn in African tea and lady's fingers (Malvaceae Family), ginger (Zingiperanceae Family), canella bark (Laureceae Family), black pepper (Piperaceae Family), cucumber seeds and vegetable marrow seeds (Cucurbitaceae Family), tomatos seed (Solanaceae Family), safflower seeds (Compositae Family), jew's mallow seed (Tiliaceae Family) and sesame (Pedaliaceae Family). Trace elements determination was made for the analysis of destructive (using super pure nitric acid and adsorbing the metal-APDC and metal-Dz complexes on activated charcoal) and nondestructive (dry seeds) samples. The method is simple, precise and sensitive for the determination of microamounts of the elements (ppm to ppb). (author)

  2. The Reconstituted Family

    Talbot, Yves


    The reconstituted or step-family is becoming more prevalent. The physician who cares for families should be acquainted with the different aspects of such family structure and family functioning. This will enable professionals to better understand and assist their patients, by anticipating the different stresses related to the new family formation, and supporting their adaptation.

  3. Family planning costs and benefits.


    Government sponsored family planning programs have had major success in declining birth rates in Barbados, China, Cuba, Hong Kong, Indonesia, Korea, Mexico, Singapore, Sri Lanka, Taiwan, and Thailand. Non- government programs have had similar success in Brazil and Colombia. These programs have been estimated as preventing over 100 million births in China and 80 million in India. Research indicates that family planning programs can produce a 30-50% drop in fertility. Family planning information and some contraceptives can be best distributed through community organizations. Research also indicates male opposition has been a major factor in wider acceptance of family planning. Surveys indicate that 50% of the woman who want no additional children are not using any birth control. Many governments do not have the resource and money to implement programs. In the developing countries if those who were able to prevent the unwanted births had birth control, the population increases in those countries would have been 1.3% versus 2.2%. In earlier family planning programs foreign assistance paid over 80% of the cost, and national governments 20%; today this is reversed. The World Bank estimates that for major improvements in population growth and women's health, $7 billion will be needed yearly by the year 2000. The countries that have had the similar goals in development of human resources, social services, health, and education. They have attended to the status of women, female employment, and maternal and child health. Estimates are that 1.3 billion couples and individuals will need family planning services by the year 2000, and this will be a formidable task. This key elements of successful family planning programs are community participation, decentralization, and training.

  9. Transposable elements in cancer.

    Burns, Kathleen H


    Transposable elements give rise to interspersed repeats, sequences that comprise most of our genomes. These mobile DNAs have been historically underappreciated - both because they have been presumed to be unimportant, and because their high copy number and variability pose unique technical challenges. Neither impediment now seems steadfast. Interest in the human mobilome has never been greater, and methods enabling its study are maturing at a fast pace. This Review describes the activity of transposable elements in human cancers, particularly long interspersed element-1 (LINE-1). LINE-1 sequences are self-propagating, protein-coding retrotransposons, and their activity results in somatically acquired insertions in cancer genomes. Altered expression of transposable elements and animation of genomic LINE-1 sequences appear to be hallmarks of cancer, and can be responsible for driving mutations in tumorigenesis.

  10. Novel porcine repetitive elements

    Nonneman Dan J


    Full Text Available Abstract Background Repetitive elements comprise ~45% of mammalian genomes and are increasingly known to impact genomic function by contributing to the genomic architecture, by direct regulation of gene expression and by affecting genomic size, diversity and evolution. The ubiquity and increasingly understood importance of repetitive elements contribute to the need to identify and annotate them. We set out to identify previously uncharacterized repetitive DNA in the porcine genome. Once found, we characterized the prevalence of these repeats in other mammals. Results We discovered 27 repetitive elements in 220 BACs covering 1% of the porcine genome (Comparative Vertebrate Sequencing Initiative; CVSI. These repeats varied in length from 55 to 1059 nucleotides. To estimate copy numbers, we went to an independent source of data, the BAC-end sequences (Wellcome Trust Sanger Institute, covering approximately 15% of the porcine genome. Copy numbers in BAC-ends were less than one hundred for 6 repeat elements, between 100 and 1000 for 16 and between 1,000 and 10,000 for 5. Several of the repeat elements were found in the bovine genome and we have identified two with orthologous sites, indicating that these elements were present in their common ancestor. None of the repeat elements were found in primate, rodent or dog genomes. We were unable to identify any of the replication machinery common to active transposable elements in these newly identified repeats. Conclusion The presence of both orthologous and non-orthologous sites indicates that some sites existed prior to speciation and some were generated later. The identification of low to moderate copy number repetitive DNA that is specific to artiodactyls will be critical in the assembly of livestock genomes and studies of comparative genomics.

  11. Fuel element store

    Wieser, R.


    The spherical fuel elements are stored dry in cans. The cans themselves are stacked in parallel storage shafts, which are combined into a rectangular storage space. The storage space is made earthquake-proof by surrounding it with concrete. It consists of a ceiling assembled from several steel parts, which is connected to the floor by support elements. A cooling air ventilation station supplies the individual storage shaft and therefore the cans with cooling air via incoming and outgoing pipes. (DG) [de

  16. Nuclear fuel element

    Penrose, R.T.; Thompson, J.R.


    A method of protecting the cladding of a nuclear fuel element from internal attack and a nuclear fuel element for use in the core of a nuclear reactor are disclosed. The nuclear fuel element has disposed therein an additive of a barium-containing material and the barium-containing material collects reactive gases through chemical reaction or adsorption at temperatures ranging from room temperature up to fuel element plenum temperatures. The additive is located in the plenum of the fuel element and preferably in the form of particles in a hollow container having a multiplicity of gas permeable openings in one portion of the container with the openings being of a size smaller than the size of the particles. The openings permit gases and liquids entering the plenum to contact the particles. The additive is comprised of elemental barium or a barium alloy containing one or more metals in addition to barium such as aluminum, zirconium, nickel, titanium and combinations thereof. 6 claims, 3 drawing figures

  1. Transversal Dirac families in Riemannian foliations

    Glazebrook, J.F.; Kamber, F.W.


    We describe a family of differential operators parametrized by the transversal vector potentials of a Riemannian foliation relative to the Clifford algebra of the foliation. This family is non-elliptic but in certain ways behaves like a standard Dirac family in the absolute case as a result of its elliptic-like regularity properties. The analytic and topological indices of this family are defined as elements of K-theory in the parameter space. We indicate how the cohomology of the parameter space is described via suitable maps to Fredholm operators. We outline the proof of a theorem of Vafa-Witten type on uniform bounds for the eigenvalues of this family using a spectral flow argument. A determinant operator is also defined with the appropriate zeta function regularization dependent on the codimension of the foliation. With respect to a generalized coupled Dirac-Yang-Mills system, we indicate how chiral anomalies are located relative to the foliation. (orig.)

  3. Families and family therapy in Hong Kong.

    Tse, Samson; Ng, Roger M K; Tonsing, Kareen N; Ran, Maosheng


    Family therapy views humans not as separate entities, but as embedded in a network of relationships, highlighting the reciprocal influences of one's behaviours on one another. This article gives an overview of family demographics and the implementation of family therapy in Hong Kong. We start with a review of the family demographics in Hong Kong and brief notes on families in mainland China. Demographics show that the landscape has changed markedly in the past decade, with more cross-border marriages, an increased divorce rate, and an ageing overall population - all of which could mean that there is increasing demand for professional family therapy interventions. However, only a limited number of professionals are practising the systems-based approach in Hong Kong. Some possible reasons as to why family therapy is not well disseminated and practised are discussed. These reasons include a lack of mental health policy to support family therapy, a lack of systematic family therapy training, and a shortage of skilled professionals. Furthermore, challenges in applying the western model in Chinese culture are also outlined. We conclude that more future research is warranted to investigate how family therapy can be adapted for Chinese families.

  4. Family doctors' involvement with families in Estonia

    Lember Margus


    Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

  7. Mobility of hobo transposable elements in non-drosophilid insects

    Atkinson, P.W.; Whyard, S.; Mende, H.A.; Pinkerton, A.C.; Coates, C.J.; Warren, W.D.; Saville, K.J.; O'Brochta, D.A.


    We will describe the development and implementation of assays which permit the mobility of hobo elements injected into developing insects embryos to be detected and examined. These assays have enabled us to classify hobo elements as members of a transposable element family which includes the Ac element of maize and the Tam3 element of snapdragon - two plant transposable elements that have wide host ranges. We will present data that show that hobo also has a wide host range in that it can excise and transpose in a number of non-drosophilid insect species. These results have led us to use hobo as a gene vector in the tephritid, Bactrocera tryoni, and we will discuss the progress of these ongoing experiments. (author)

  8. Alphavirus replicon approach to promoterless analysis of IRES elements.

    Kamrud, K I; Custer, M; Dudek, J M; Owens, G; Alterson, K D; Lee, J S; Groebner, J L; Smith, J F


    Here we describe a system for promoterless analysis of putative internal ribosome entry site (IRES) elements using an alphavirus (family Togaviridae) replicon vector. The system uses the alphavirus subgenomic promoter to produce transcripts that, when modified to contain a spacer region upstream of an IRES element, allow analysis of cap-independent translation of genes of interest (GOI). If the IRES element is removed, translation of the subgenomic transcript can be reduced >95% compared to the same transcript containing a functional IRES element. Alphavirus replicons, used in this manner, offer an alternative to standard dicistronic DNA vectors or in vitro translation systems currently used to analyze putative IRES elements. In addition, protein expression levels varied depending on the spacer element located upstream of each IRES. The ability to modulate the level of expression from alphavirus vectors should extend the utility of these vectors in vaccine development.

Using this transport device, adjacent ponds can be served through the passage openings. (DG) [de

  10. Nuclear fuel element

    Hirayama, Satoshi; Kawada, Toshiyuki; Matsuzaki, Masayoshi.


    Purpose: To provide a fuel element for reducing the mechanical interactions between a fuel-cladding tube and the fuel element and for alleviating the limits of the operating conditions of a reactor. Constitution: A fuel element having mainly uranium dioxide consists of a cylindrical outer pellet and cylindrical inner pellet inserted into the outer pellet. The outer pellet contains two or more additives selected from aluminium oxide, beryllium oxide, magnesium oxide, silicon oxide, sodium oxide, phosphorus oxide, calcium oxide and iron oxide, and the inner pellet contains nuclear fuel substance solely or one additive selected from calcium oxide, silicon oxide, aluminium oxide, magnesium oxide, zirconium oxide and iron oxide. The outer pellet of the fuel thus constituted is reduced in mechanical strength and also in the mechanical interactions with the cladding tube, and the plastic fluidity of the entire pellet is prevented by the inner pellet increased in the mechanical strength.

  11. Creativity Management Key Elements

    Rosa María Fuchs Ángeles


    Full Text Available Organizations are constantly looking towards innovation. In order to reach it they must foment creativity. This paper analyzes a series of elements considered in the organizational creativity management and proposes a model with the indispensable factors that organizations should consider to reach it. These elements are: culture and organizational environment, strategy, structure, communication, relation with customers, human resources (recruiting, training, job design, compensation, promotion, and performance evaluation, long term orientation and the organizational life cycle. Having the analysis of those elements as a basis, the indispensable pillars on management creativity are identified. The proposed model is based on 5 pillars: the alignment between strategic, culture and organizational structure, called by the authors 'Holy Trinity'; intern publicity; customer’s voice; recognition and a look towards future. Finally, the case of an innovative Peruvian enterprise is presented from the model’s perspective and the study conclusions.

  18. Mathematical Models of the Sinusoidal Screen Family

    Tajana Koren


    Full Text Available In this paper we will define a family of sinusoidal screening elements and explore the possibilities of their application in graphic arts, securities printing and design solutions in photography and typography editing. For this purpose mathematical expressions of sinusoidal families were converted into a Postscript language. The introduction of a random variable results in a countless number of various mutations which cannot be repeated without knowing the programming code itself. The use of the family of screens in protection of securities is thus of great importance. Other possible application of modulated sinusoidal screens is related to the large format color printing. This paper will test the application of sinusoidal screens in vector graphics, pixel graphics and typography. The development of parameters in the sinusoidal screen element algorithms gives new forms defined within screening cells with strict requirements of coverage implementation. Individual solutions include stochastic algorithms, as well as the autonomy of screening forms in regard to multicolor printing channels.

  14. Family emotional expressiveness and family structure

    Čotar-Konrad Sonja


    Full Text Available The present paper scrutinizes the relationship between family emotional expressiveness (i.e., the tendency to express dominant and/or submissive positive and negative emotions and components of family structure as proposed in Olson’s Circumplex model (i.e., cohesion and flexibility, family communication, and satisfaction in families with adolescents. The study was conducted on a sample of 514 Slovenian adolescents, who filled out two questionnaires: the Slovenian version of Family Emotional Expressiveness - FEQ and FACES IV. The results revealed that all four basic dimensions of family functioning were significantly associated with higher/more frequent expressions of positive submissive emotions, as well as with lower/less frequent expressions of negative dominant emotions. Moreover, expressions of negative submissive emotions explained a small, but significant amount of variance in three out of four family functioning variables (satisfaction, flexibility, and communication. The importance of particular aspects of emotional expressiveness for family cohesion, flexibility, communication, and satisfaction is discussed, and the relevance of present findings for family counselling is outlined.

  15. Nontraditional family romance.

    Corbett, K


    Family stories lie at the heart of psychoanalytic developmental theory and psychoanalytic clinical technique, but whose family? Increasingly, lesbian and gay families, multiparent families, and single-parent families are relying on modern reproductive technologies to form families. The contemplation of these nontraditional families and the vicissitudes of contemporary reproduction lead to an unknowing of what families are, including the ways in which psychoanalysts configure the family within developmental theory. This article focuses on the stories that families tell in order to account for their formation--stories that include narratives about parental union, parental sexuality, and conception. The author addresses three constructs that inform family stories and that require rethinking in light of the category crises posed by and for the nontraditional family: (1) normative logic, (2) family reverie and the construction of a family romance, and (3) the primal scene. These constructs are examined in tandem with detailed clinical material taken from the psychotherapy of a seven-year-old boy and his two mothers.

  20. Final Report of the Project "From the finite element method to the virtual element method"

    Manzini, Gianmarco [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Gyrya, Vitaliy [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)


    The Finite Element Method (FEM) is a powerful numerical tool that is being used in a large number of engineering applications. The FEM is constructed on triangular/tetrahedral and quadrilateral/hexahedral meshes. Extending the FEM to general polygonal/polyhedral meshes in straightforward way turns out to be extremely difficult and leads to very complex and computationally expensive schemes. The reason for this failure is that the construction of the basis functions on elements with a very general shape is a non-trivial and complex task. In this project we developed a new family of numerical methods, dubbed the Virtual Element Method (VEM) for the numerical approximation of partial differential equations (PDE) of elliptic type suitable to polygonal and polyhedral unstructured meshes. We successfully formulated, implemented and tested these methods and studied both theoretically and numerically their stability, robustness and accuracy for diffusion problems, convection-reaction-diffusion problems, the Stokes equations and the biharmonic equations.

  2. Nuclear fuel element

    Armijo, J S; Coffing, L F


    The fuel element with circular cross-section for BWR and PWR consists of a core surrounded by a compound jacket container where there is a gap between the core and jacket during operation in the reactor. The core consists of U, Pu, Th compounds and mixtures of these. The compound jacket consists of zircaloy 2 or 4. In order to for example prevent the corrosion of the compound jacket, its inner surface has a metal barrier with smaller neutron absorbers than the jacket material in the form of a zirconium sponge. The zirconium of this metal barrier has impurities of various elements in the order of magnitude of 1000 to 5000 ppm. The oxygen content is in the range of 200 to 1200 ppm and the thickness of the metal barrier is 1-30% of the thickness of the jacket.

  7. Periodic table of elements

    Fluck, E.; Heumann, K.G.


    Following a recommendation by the International Union for Pure and Applied Chemistry (IUPAC), the groups of the periodic table shall be numbered from 1 to 18, instead of I to VIII as before. The recommendations has been approved of by the Committee on Nomenclature of the American Chemical Society. The new system abandons the distinction between main groups (a) and auxiliary groups (b), which in the past frequently has been the reason for misunderstandings between European and American chemists, due to different handling. The publishing house VCH Verlagsgesellschaft recently produced a new periodic table that shows the old and the new numbering system together at a glance, so that chemists will have time to get familiar with the new system. In addition the new periodic table represents an extensive data compilation arranged by elements. The front page lists the chemical properties of elements, the back page their physical properties.

  8. Nuclear fuel elements

    Kawada, Toshiyuki; Hirayama, Satoshi; Yoneya, Katsutoshi.


    Purpose: To enable load-depending operation as well as moderation for the restriction of operation conditions in the present nuclear reactors, by specifying the essential ingredients and the total weight of the additives to UO 2 fuel substances. Constitution: Two or more additives selected from Al 2 O 3 , B 2 O, CaO, MgO, SiO 2 , Na 2 O and P 2 O 5 are added by the total weight of 2 - 5% to fuel substances consisting of UO 2 or a mixture of UO 2 and PuO 2 . When the mixture is sintered, the strength of the fuel elements is decreased and the fuel-cladding interactions due to the difference in the heat expansion coefficients between the ceramic fuel elements and the metal claddings are decreased to a substantially harmless degree.

  9. Nuclear fuel elements

    Nakai, Keiichi


    Purpose: To decrease the tensile stresses resulted in a fuel can as well as prevent decladding of fuel pellets into the bore holes by decreasing the inner pressure within the nuclear fuel element. Constitution: A fuel can is filled with hollow fuel pellets, inserted with a spring for retaining the hollow fuel pellets with an appropriate force and, thereafter, closely sealed at the both ends with end plugs. A cylindrical body is disposed into the bore holes of the hollow fuel pellets. Since initial sealing gases and/or gaseous nuclear fission products can thus be excluded from the bore holes where the temperature is at the highest level, the inner pressure of the nuclear fuel element can be reduced to decrease the tensile strength resulted to the fuel can. Furthermore, decladding of fuel pellets into the bore holes can be prevented. (Moriyama, K.)

  10. Peculiarities of rare-earth-element distribution in environmental objects

    Gorbunov, A.V.; Onischenko, T.L.; Gundorina, S.F.; Frontasyeva, M.V.


    The effect of the production of phosphorus fertilizers on the pollution of the environment by rare-earth elements is reviewed. The main sources of rare-earth element pollution in the environment are described. The levels of REEs in components of the environment - atmosphere, snow, different types of soil, native and agricultural types of vegetation - that provide evidence for their participation in the biological cycle of plants are considered. The high values of the correlation coefficients lead one to think that the REE distribution in vegetation occurs under specific laws true for this family of elements.

  18. Helium the disappearing element

    Sears, Wheeler M


    The subject of the book is helium, the element, and its use in myriad applications including MRI machines, particle accelerators, space telescopes, and of course balloons and blimps. It was at the birth of our Universe, or the Big Bang, where the majority of cosmic helium was created; and stellar helium production continues. Although helium is the second most abundant element in the Universe, it is actually quite rare here on Earth and only exists because of radioactive elements deep within the Earth. This book includes a detailed history of the discovery of helium, of the commercial industry built around it, how the helium we actually encounter is produced within the Earth, and the state of the helium industry today. The gas that most people associate with birthday party balloons is running out. “Who cares?” you might ask. Well, without helium, MRI machines could not function, rockets could not go into space, particle accelerators such as those used by CERN could not operate, fiber optic cables would not...

  20. Using Finite Element Method

    M.H.R. Ghoreishy


    Full Text Available This research work is devoted to the footprint analysis of a steel-belted radial tyre (185/65R14 under vertical static load using finite element method. Two models have been developed in which in the first model the tread patterns were replaced by simple ribs while the second model was consisted of details of the tread blocks. Linear elastic and hyper elastic (Arruda-Boyce material models were selected to describe the mechanical behavior of the reinforcing and rubbery parts, respectively. The above two finite element models of the tyre were analyzed under inflation pressure and vertical static loads. The second model (with detailed tread patterns was analyzed with and without friction effect between tread and contact surfaces. In every stage of the analysis, the results were compared with the experimental data to confirm the accuracy and applicability of the model. Results showed that neglecting the tread pattern design not only reduces the computational cost and effort but also the differences between computed deformations do not show significant changes. However, more complicated variables such as shape and area of the footprint zone and contact pressure are affected considerably by the finite element model selected for the tread blocks. In addition, inclusion of friction even in static state changes these variables significantly.

  1. Study of Superheavy Elements

    Hofmann, Sigurd


    The nuclear shell model predicts that the next doubly magic shell-closure beyond 208 Pb is at a proton number Z = 114, 120, or 126 and at a neutron number N = 172 or 184. The outstanding aim of experimental investigations is the exploration of this region of spherical 'SuperHeavy Elements' (SHEs). Experimental methods are described, which allowed for the identification of elements produced on a cross-section level of about 1 pb. The decay data reveal that for the heaviest elements, the dominant decay mode is alpha emission, not fission. Decay properties as well as reaction cross-sections are compared with results of theoretical investigations. Finally, plans are presented for the further development of the experimental set-up and the application of new techniques, as for instance the precise mass measurement of the produced nuclei using ion traps. At increased sensitivity, the detailed exploration of the region of spherical SHEs will start, after first steps on the island were made in recent years. (Author)

  2. Probabilistic finite elements

    Belytschko, Ted; Wing, Kam Liu


    In the Probabilistic Finite Element Method (PFEM), finite element methods have been efficiently combined with second-order perturbation techniques to provide an effective method for informing the designer of the range of response which is likely in a given problem. The designer must provide as input the statistical character of the input variables, such as yield strength, load magnitude, and Young's modulus, by specifying their mean values and their variances. The output then consists of the mean response and the variance in the response. Thus the designer is given a much broader picture of the predicted performance than with simply a single response curve. These methods are applicable to a wide class of problems, provided that the scale of randomness is not too large and the probabilistic density functions possess decaying tails. By incorporating the computational techniques we have developed in the past 3 years for efficiency, the probabilistic finite element methods are capable of handling large systems with many sources of uncertainties. Sample results for an elastic-plastic ten-bar structure and an elastic-plastic plane continuum with a circular hole subject to cyclic loadings with the yield stress on the random field are given.

  3. New functionalities in abundant element oxides: ubiquitous element strategy

    Hosono, Hideo; Hayashi, Katsuro; Kamiya, Toshio; Atou, Toshiyuki; Susaki, Tomofumi


    While most ceramics are composed of ubiquitous elements (the ten most abundant elements within the Earth's crust), many advanced materials are based on rare elements. A 'rare-element crisis' is approaching owing to the imbalance between the limited supply of rare elements and the increasing demand. Therefore, we propose a 'ubiquitous element strategy' for materials research, which aims to apply abundant elements in a variety of innovative applications. Creation of innovative oxide materials and devices based on conventional ceramics is one specific challenge. This review describes the concept of ubiquitous element strategy and gives some highlights of our recent research on the synthesis of electronic, thermionic and structural materials using ubiquitous elements.

  4. Characterization of Transposable Elements in Laccaria bicolor

    Labbe, Jessy L [ORNL; Murat, Claude [INRA, Nancy, France; Morin, Emmanuelle [INRA, Nancy, France; Tuskan, Gerald A [ORNL; Le Tacon, F [UMR, France; Martin, Francis [INRA, Nancy, France


    Background: The publicly available Laccaria bicolor genome sequence has provided a considerable genomic resource allowing systematic identification of transposable elements (TEs) in this symbiotic ectomycorrhizal fungus. Using a TE-specific annotation pipeline we have characterized and analyzed TEs in the L. bicolor S238N-H82 genome. Methodology/Principal Findings: TEs occupy 24% of the 60 Mb L. bicolor genome and represent 25,787 full-length and partial copies elements distributed within 172 families. The most abundant elements were the Copia-like. TEs are not randomly distributed across the genome, but are tightly nested or clustered. The majority of TEs are ancient except some terminal inverted repeats (TIRS), long terminal repeats (LTRs) and a large retrotransposon derivative (LARD) element. There were three main periods of TEs expansion in L. bicolor; the first from 57 to 10 Mya, the second from 5 to 1 Mya and the most recent from 500,000 years ago until now. LTR retrotransposons are closely related to retrotransposons found in another basidiomycete, Coprinopsis cinerea. Conclusions: This analysis represents an initial characterization of TEs in the L. bicolor genome, contributes to genome assembly and to a greater understanding of the role TEs played in genome organization and evolution, and provides a valuable resource for the ongoing Laccaria Pan-Genome project supported by the U.S.-DOE Joint Genome Institute.

  5. The application of hospitality elements in hospitals.

    Wu, Ziqi; Robson, Stephani; Hollis, Brooke


    In the last decade, many hospital designs have taken inspiration from hotels, spurred by factors such as increased patient and family expectations and regulatory or financial incentives. Increasingly, research evidence suggests the value of enhancing the physical environment to foster healing and drive consumer decisions and perceptions of service quality. Although interest is increasing in the broader applicability of numerous hospitality concepts to the healthcare field, the focus of this article is design innovations, and the services that such innovations support, from the hospitality industry. To identify physical hotel design elements and associated operational features that have been used in the healthcare arena, a series of interviews with hospital and hotel design experts were conducted. Current examples and suggestions for future hospitality elements were also sought from the experts, academic journals, and news articles. Hospitality elements applied in existing hospitals that are addressed in this article include hotel-like rooms and decor; actual hotels incorporated into medical centers; hotel-quality food, room service, and dining facilities for families; welcoming lobbies and common spaces; hospitality-oriented customer service training; enhanced service offerings, including concierges; spas or therapy centers; hotel-style signage and way-finding tools; and entertainment features. Selected elements that have potential for future incorporation include executive lounges and/or communal lobbies with complimentary wireless Internet and refreshments, centralized controls for patients, and flexible furniture. Although the findings from this study underscore the need for more hospitality-like environments in hospitals, the investment decisions made by healthcare executives must be balanced with cost-effectiveness and the assurance that clinical excellence remains the top priority.

  6. The Relations of Family Members’ Unique and Shared Perspectives of Family Dysfunction to Dyad Adjustment

    Jager, Justin; Yuen, Cynthia X.; Bornstein, Marc H.; Putnick, Diane L.; Hendricks, Charlene


    Among a community sample of families (N = 128), this study examined how family members’ shared and unique perspectives of family dysfunction relate to dyad members’ shared views of dyad adjustment within adolescent-mother, adolescent-father, and mother-father dyads. Independent of a family’s family perspective (shared perspective of family dysfunction), the adolescent’s unique perspective was associated with lower security and higher conflict with both mother and father, the father’s unique perspective was associated with lower security and higher conflict with the adolescent as well as lower marital quality with mother, and the mother unique perspective was associated with lower marital quality with the father. Moreover, for adolescent-parent dyads, compared to the parent unique perspective, the adolescent unique perspective was more strongly associated with dyad adjustment. These findings indicate that both shared and unique views of the family system – the adolescent’s unique view in particular - independently relate to the health of family subsystems. They also suggest that research as well as therapeutic interventions that focus on just the shared view of the family may miss important elements of family dysfunction. PMID:24884682

  7. The transuranium elements: From neptunium and plutonium to element 112

    Hoffman, D.C.


    Beginning in the 1930's, both chemists and physicists became interested in synthesizing new artificial elements. The first transuranium element, Np, was synthesized in 1940. Over the past six decades, 20 transuranium elements have been produced. A review of the synthesis is given. The procedure of naming the heavy elements is also discussed. It appears feasible to produce elements 113 and 114. With the Berkeley Gas-filled Separator, it should be possible to reach the superheavy elements in the region of the spherical Z=114 shell, but with fewer neutrons than the N=184 spherical shell. 57 refs, 6 figs

  8. The mobile genetic element Alu in the human genome

    Novick, G.E. [Florida International Univ., Miami, FL (United States); Batzer, M.A.; Deininger, P.L. [Louisiana State Univ. Medical Center, New Orleans, LA (United States)] [and others


    Genetic material has been traditionally envisioned as relatively static with the exception of occasional, often deleterious mutations. The sequence DNA-to-RNA-to-protein represented for many years the central dogma relating gene structure and function. Recently, the field of molecular genetics has provided revolutionary information on the dynamic role of repetitive elements in the function of the genetic material and the evolution of humans and other organisms. Alu sequences represent the largest family of short interspersed repetitive elements (SINEs) in humans, being present in an excess of 500,000 copies per haploid genome. Alu elements, as well as the other repetitive elements, were once considered to be useless. Today, the biology of Alu transposable elements is being widely examined in order to determine the molecular basis of a growing number of identified diseases and to provide new directions in genome mapping and biomedical research. 66 refs., 5 figs.

  13. Resilience of refugee families

    Batić Dragana


    Full Text Available This study attempted to find a correlation between the trauma of family members of war and exile, and the characteristics of family functioning and lasted from 1992-1995. The term “family resilience” refers to the processes of adaptation and coping in the family as a functional unit. This paper presents a study of refugee families from Bosnia, who lived in refugee camps in Macedonia during the war of 1992- 1995. Data were obtained by interviews, observations, and a number of psychological instruments especially for children and parents, which measured the effects of psychological stress and family relationships.

  5. Elements of social action

    Marjanović Miloš


    Full Text Available Because of the significant analytical advantages, the author prefers social action as initial sociological concept in the relation to social phenomenon. Its basic elements are: actors, subjects and tools, needs and interests, values and norms, positions and roles. Actors set in motion and unify the rest of elements, guide to the magic triangle of sociology (movement, change, order, reaffirm actor paradigm to systemic paradigm. Subjects and tools materialize an action and its overestimate results in technological determinism or (by means of property as institutional appropriation of nature in the (unclassed historical type of society. Needs and interests are the basis of person's motivation and starting point for depth analysis of sociability. The expansion of legitimate interests circle develops techniques of normative regulation. Values and norms guide to institutional-organizational, positions to vertical and roles to horizontal structure. Values give the meaning to the action as well as to human existence, they are orientations of motivate system of personality but also basic aspect of society. As abstractions, values are latent background of norms and they tell to us what to do, and norms how to do something. Norms are specified instructions for suitable behavior Without normative order, not to be possible the satisfying of needs and the conciliation of interests. Riches, power and prestige are components of social position, and legal status is the determination of rights and obligations of the position. Roles are normative expectation of behavior. Toward kinds of sanctions roles are classified. Roles but also other elements of social action are starting point for sociological analysis of legal norms and institutes. On the other side, the observation of legal component of social actions enriches, strengths and precises sociological analysis of them.

  17. Trace elements record complex histories in diogenites

    Balta, J. B.; Beck, A. W.; McSween, H. Y.


    Diogenite meteorites are cumulate rocks composed mostly of orthopyroxene and chemically linked to eucrites (basaltic) and howardites (brecciated mixtures of diogenites and eucrites). Together, they represent the largest single family of achondrite meteorites delivered to Earth, and have been spectrally linked to the asteroid 4 Vesta, the largest remaining basaltic protoplanet. However, this spectral link is non-unique as many basaltic asteroids likely formed and were destroyed in the early solar system. Recent work suggested that Vesta may be an unlikely parent body for the diogenites based on correlations between trace elements and short-lived isotope decay products, which would be unlikely to survive on a body as large as Vesta due to its long cooling history [1]. Recent analyses of terrestrial and martian olivines have demonstrated that trace element spatial distributions can preserve evidence of their crystallization history even when major elements have been homogenized [2]. We have mapped minor elements including Cr, Al, and Ti in seemingly homogeneous diogenite orthopyroxenes and found a variety of previously unobserved textures. The pyroxenes in one sample (GRA 98108) are seemingly large grains of variable shapes and sizes, but the trace elements reveal internal grain boundaries between roughly-equal sized original subgrains, with equilibrated metamorphic triple junctions between them and trace element depletions at the boundaries. These trends suggest extraction of trace elements by a magma along those relict grain boundaries during a reheating event. Two other samples show evidence of fracturing and annealing, with trace element mobility within grains. One sample appears to have remained a closed system during annealing (MET 01084), while the other has interacted with a fluid or magma to move elements along annealed cracks (LEW 88679). These relict features establish that the history of diogenite pyroxenes is more complex than their homogeneous major

  20. Nuclear fuel element

    Iwano, Yoshihiko.


    Microfine cracks having a depth of less than 10% of a pipe thickness are disposed radially from a central axis each at an interval of less than 100 micron over the entire inner circumferential surface of a zirconium alloy fuel cladding tube. For manufacturing such a nuclear fuel element, the inside of the cladding tube is at first filled with an electrolyte solution of potassium chloride. Then, electrolysis is conducted using the cladding tube as an anode and the electrolyte solution as a cathode, and the inner surface of the cladding tube with a zirconium dioxide layer having a predetermined thickness. Subsequently, the cladding tube is laid on a smooth steel plate and lightly compressed by other smooth steel plate to form microfine cracks in the zirconium dioxide layer on the inner surface of the cladding tube. Such a compressing operation is continuously applied to the cladding tube while rotating the cladding tube. This can inhibit progress of cracks on the inner surface of the cladding tube, thereby enabling to prevent failure of the cladding tube even if a pellet/cladding tube mechanical interaction is applied. Accordingly, reliability of the nuclear fuel elements is improved. (I.N.)

  1. Heavy-element nucleosynthesis

    Mathews, G.J.


    New measurements and theoretical studies of nuclear properties, together with new astronomical data on the growth of heavy-element abundances during the early history of the Galaxy, now provide a clearer picture of where in nature the elements heavier than iron are produced by rapid (r-process) and show (s-process) neutron capture reactions. The nuclear data suggest that the r-process involves a high-neutron-density beta-flow equilibrium environment and that the s-process may have occurred at a temperature and neutron density consistent with a 13 C(α,n) 16 0 neutron source. The astronomical data, when compared with simple galactic chemical evolution modes, suggests that the r-process is associated with type II supernovae and that the neutron source must be manufactured by the star. Low-mass type II supernovae are proposed as the most important contributors to the r-process. A 13 C neutron source in intermediate-mass stars is proposed for the s-process. 64 refs., 7 figs

  2. Improved nuclear fuel element


    The invention is of a nuclear fuel element which comprises a central core of a body of nuclear fuel material selected from the group consisting of compounds of uranium, plutonium, thorium and mixtures thereof, and an elongated composite cladding container comprising a zirconium alloy tube containing constituents other than zirconium in an amount greater than about 5000 parts per million by weight and an undeformed metal barrier of moderate purity zirconium bonded to the inside surface of the alloy tube. The container encloses the core so as to leave a gap between the container and the core during use in a nuclear reactor. The metal barrier is of moderate purity zirconium with an impurity level on a weight basis of at least 1000ppm and less than 5000ppm. Impurity levels of specific elements are given. Variations of the invention are also specified. The composite cladding reduces chemical interaction, minimizes localized stress and strain corrosion and reduces the likelihood of a splitting failure in the zirconium alloy tube. Other benefits are claimed. (U.K.)

  3. Disrupted Refugee Family Life

    Fleeing civil war involves managing life threatening events and multiple disruptions of everyday life. The theoretical potentials of analysing the recreation of everyday family life among Syrian refugees in Denmark is explored based on conceptualizations that emphasize the collective agency...... of family members in social historical contexts. Studying the multiple perspectives of family members shows how social support conceptualized as care practises is conflictual in the changing everyday family practices that are transformed by policy. The purpose of studying how families manage to flee civil...... war and struggle to recreate an everyday life in exile is to contribute with contextualization and expansion of mainstream understandings of family life, suffering, and resilience in refugee family trajectories in multiple contexts....

  4. Inside the Family Firm

    Bennedsen, Morten; Nielsen, Kasper; Pérez-González, Francisco


    This paper uses a unique dataset from Denmark to investigate (1) the role of family characteristics in corporate decision making, and (2) the consequences of these decisions on firm performance. We focus on the decision to appoint either a family or an external chief executive officer (CEO). We...... show that a departing CEO's family characteristics have a strong predictive power in explaining CEO succession decisions: family CEOs are more frequently selected the larger the size of the family, the higher the ratio of male children and when the departing CEOs had only had one spouse. We...... then analyze the impact of family successions on performance. We overcome endogeneity and omitted variables problems of previous papers in the literature by using the gender of a departing CEO's first-born child as an instrumental variable (IV) for family successions. This is a plausible IV as male first...

  6. Multiplex families with epilepsy

    Afawi, Zaid; Oliver, Karen L.; Kivity, Sara; Mazarib, Aziz; Blatt, Ilan; Neufeld, Miriam Y.; Helbig, Katherine L.; Goldberg-Stern, Hadassa; Misk, Adel J.; Straussberg, Rachel; Walid, Simri; Mahajnah, Muhammad; Lerman-Sagie, Tally; Ben-Zeev, Bruria; Kahana, Esther; Masalha, Rafik; Kramer, Uri; Ekstein, Dana; Shorer, Zamir; Wallace, Robyn H.; Mangelsdorf, Marie; MacPherson, James N.; Carvill, Gemma L.; Mefford, Heather C.; Jackson, Graeme D.; Scheffer, Ingrid E.; Bahlo, Melanie; Gecz, Jozef; Heron, Sarah E.; Corbett, Mark; Mulley, John C.; Dibbens, Leanne M.; Korczyn, Amos D.


    Objective: To analyze the clinical syndromes and inheritance patterns of multiplex families with epilepsy toward the ultimate aim of uncovering the underlying molecular genetic basis. Methods: Following the referral of families with 2 or more relatives with epilepsy, individuals were classified into epilepsy syndromes. Families were classified into syndromes where at least 2 family members had a specific diagnosis. Pedigrees were analyzed and molecular genetic studies were performed as appropriate. Results: A total of 211 families were ascertained over an 11-year period in Israel. A total of 169 were classified into broad familial epilepsy syndrome groups: 61 generalized, 22 focal, 24 febrile seizure syndromes, 33 special syndromes, and 29 mixed. A total of 42 families remained unclassified. Pathogenic variants were identified in 49/211 families (23%). The majority were found in established epilepsy genes (e.g., SCN1A, KCNQ2, CSTB), but in 11 families, this cohort contributed to the initial discovery (e.g., KCNT1, PCDH19, TBC1D24). We expand the phenotypic spectrum of established epilepsy genes by reporting a familial LAMC3 homozygous variant, where the predominant phenotype was epilepsy with myoclonic-atonic seizures, and a pathogenic SCN1A variant in a family where in 5 siblings the phenotype was broadly consistent with Dravet syndrome, a disorder that usually occurs sporadically. Conclusion: A total of 80% of families were successfully classified, with pathogenic variants identified in 23%. The successful characterization of familial electroclinical and inheritance patterns has highlighted the value of studying multiplex families and their contribution towards uncovering the genetic basis of the epilepsies.

At least one of the elements may contain silicon. (author)

  8. Trace element emissions from coal



    Trace elements are emitted during coal combustion. The quantity, in general, depends on the physical and chemical properties of the element itself, the concentration of the element in the coal, the combustion conditions and the type of particulate control device used, and its collection efficiency as a function of particle size. Some trace elements become concentrated in certain particle streams following combustion such as bottom ash, fly ash, and flue gas particulate matter, while others do not. Various classification schemes have been developed to describe this partitioning behaviour. These classification schemes generally distinguish between: Class 1: elements that are approximately equally concentrated in the fly ash and bottom ash, or show little or no fine particle enrichment, examples include Mn, Be, Co and Cr; Class 2: elements that are enriched in the fly ash relative to bottom ash, or show increasing enrichment with decreasing particle size, examples include As, Cd, Pb and Sb; Class 3: elements which are emitted in the gas phase (primarily Hg (not discussed in this review), and in some cases, Se). Control of class 1 trace elements is directly related to control of total particulate matter emissions, while control of the class 2 elements depends on collection of fine particulates. Due to the variability in particulate control device efficiencies, emission rates of these elements can vary substantially. The volatility of class 3 elements means that particulate controls have only a limited impact on the emissions of these elements.

  10. Accelerator vacuum system elements

    Sivokon', V.V.; Kobets, A.F.; Shvetsov, V.A.; Sivokon', L.V.


    Some elements of vacuum systems are investigated. Considerable attention has been given to the investigation into peculiarities in pumping out of a ionoguide for transportation of an accelerated charged particles beam the spread of which often attains a considerable length. The number of pumps over the ionoguide length is experimentally determined. It is shown that as a result of ionoguide warm-up the pumping out time is considerably reduced maximum permissible pressure is decreased by two orders and lesser rate of pump pumping out is required. The investigations have shown that when operating the ionoguide there is no necessity in setting up seals between the ionoguide and magnetodischarged pump. The causes of the phenomenon in which the pressure near the pump is greater than in the end of the ionoguide, are impurities carried in by the pump into the ionoguide volume and the pumping out capacity of the pressure converter

  12. Improved nuclear fuel element


    A nuclear fuel element for use in the core of a nuclear reactor is disclosed and has a metal liner disposed between the cladding and the nuclear fuel material and a high lubricity material in the form of a coating disposed between the liner and the cladding. The liner preferably has a thickness greater than the longest fission product recoil distance and is composed of a low neutron capture cross-section material. The liner is preferably composed of zirconium, an alloy of zirconium, niobium or an alloy of niobium. The liner serves as a preferential reaction site for volatile impurities and fission products and protects the cladding from contact and reaction with such impurities and fission products. The high lubricity material acts as an interface between the liner and the cladding and reduces localized stresses on the cladding due to fuel expansion and cracking of the fuel

  13. Probabilistic fracture finite elements

    Liu, W. K.; Belytschko, T.; Lua, Y. J.


    The Probabilistic Fracture Mechanics (PFM) is a promising method for estimating the fatigue life and inspection cycles for mechanical and structural components. The Probability Finite Element Method (PFEM), which is based on second moment analysis, has proved to be a promising, practical approach to handle problems with uncertainties. As the PFEM provides a powerful computational tool to determine first and second moment of random parameters, the second moment reliability method can be easily combined with PFEM to obtain measures of the reliability of the structural system. The method is also being applied to fatigue crack growth. Uncertainties in the material properties of advanced materials such as polycrystalline alloys, ceramics, and composites are commonly observed from experimental tests. This is mainly attributed to intrinsic microcracks, which are randomly distributed as a result of the applied load and the residual stress.

    Obara, Hiroshi.


    Purpose: To suppress iodine release thereby prevent stress corrosion cracks in fuel cans by dispersing ferrous oxide at the outer periphery of sintered uranium dioxide pellets filled and sealed within zirconium alloy fuel cans of fuel elements. Constitution: Sintered uranium dioxide pellets to be filled and sealed within a zirconium alloy fuel can are prepared either by mixing ferric oxide powder in uranium dioxide powder, sintering and then reducing at low temperature or by mixing iron powder in uranium dioxide powder, sintering and then oxidizing at low temperature. In this way, ferrous oxide is dispersed on the outer periphery of the sintered uranium dioxide pellets to convert corrosive fission products iodine into iron iodide, whereby the iodine release is suppressed and the stress corrosion cracks can be prevented in the fuel can.

    Hirama, H.


    A nuclear fuel element comprises an elongated tube having upper and lower end plugs fixed to both ends thereof and nuclear fuel pellets contained within the tube. The fuel pellets are held against the lower end plug by a spring which is supported by a setting structure. The setting structure is maintained at a proper position at the middle of the tube by a wedge effect caused by spring force exerted by the spring against a set of balls coacting with a tapered member of the setting structure thereby wedging the balls against the inner wall of the tube, and the setting structure is moved free by pushing with a push bar against the spring force so as to release the wedge effect

  16. Finite element modelling

    Tonks, M.R.; Williamson, R.; Masson, R.


    The Finite Element Method (FEM) is a numerical technique for finding approximate solutions to boundary value problems. While FEM is commonly used to solve solid mechanics equations, it can be applied to a large range of BVPs from many different fields. FEM has been used for reactor fuels modelling for many years. It is most often used for fuel performance modelling at the pellet and pin scale, however, it has also been used to investigate properties of the fuel material, such as thermal conductivity and fission gas release. Recently, the United Stated Department Nuclear Energy Advanced Modelling and Simulation Program has begun using FEM as the basis of the MOOSE-BISON-MARMOT Project that is developing a multi-dimensional, multi-physics fuel performance capability that is massively parallel and will use multi-scale material models to provide a truly predictive modelling capability.

Phase studies were done on Rb 2 UO 4 , K 2 UO 4 , Li 2 UO 4 , and Es 2 U 2 O 7 . The lithium neptunate (VI) system was investigated and the existence of Li 2 NpO 4 was established. In oxidation-reduction studies it was shown that Am(III) can be electrolytically oxidized to Am(IV) in strong H 3 PO 4 , but Cf(III) and Pr(III) do not oxidize. The low-temperature absorption spectrum of thin films of NpBr 3 was investigated. (U.S.)


    Maximiliano Emanuel Korstanje


    Full Text Available Modern studies emphasized on the needs of researching the hospitality as relevant aspects of tourism and hospitality fields. Anyway, these approaches are inextricably intertwined to the industry of tourism and do not take seriously the anthropological and sociological roots of hospitality. In fact, the hotel seems to be a partial sphere of hospitality at all. Under this context, the present paper explores the issue of hospitality enrooted in the political and economic indo-European principle of free-transit which is associated to a much broader origin.  Starting from the premise etymologically hostel and hospital share similar origins, we follow the contributions of J Derrida to determine the elements that formed the hospitality up to date.

  1. [Family therapy of encopresis].

    Spitczok von Brisinski, Ingo; Lüttger, Fred


    Encopresis is a taboo symptom, which is connected with great suffering from mental pressure not only for the children concerned, but also their relatives. Family related approaches are indispensable to understand encopresis, because as a result of high symptom persistence and psychological comorbidity in many cases a purely behavior-therapeutic, symptom focused approach is not sufficient, and further psychotherapeutic interventions are necessary. There is a strong temporal correlation between family interaction and frequency of soiling and changes of interaction influence changes in soiling more than the other way round. In a literature review different family relationship patterns and approaches of family therapy are represented regarding encopresis. Meaningful differences for family therapy are represented regarding primary/secondary encopresis, encopresis with/without comorbid psychiatric disorder as well as encopresis with/without dysfunctional family interaction. Distinctions are made between symptom focused, not-symptom focused and combined family therapeutic approaches, which are illustrated with case examples of outpatient and inpatient treatment. Symptom focused family therapy like e.g. externalizing of the soiling is helpful also if no dysfunctional family interaction patterns are present, because all family members can contribute to treatment success according to their own resources.

  2. Extended family medicine training

    Slade, Steve; Ross, Shelley; Lawrence, Kathrine; Archibald, Douglas; Mackay, Maria Palacios; Oandasan, Ivy F.


    Abstract Objective To examine trends in family medicine training at a time when substantial pedagogic change is under way, focusing on factors that relate to extended family medicine training. Design Aggregate-level secondary data analysis based on the Canadian Post-MD Education Registry. Setting Canada. Participants All Canadian citizens and permanent residents who were registered in postgraduate family medicine training programs within Canadian faculties of medicine from 1995 to 2013. Main outcome measures Number and proportion of family medicine residents exiting 2-year and extended (third-year and above) family medicine training programs, as well as the types and numbers of extended training programs offered in 2015. Results The proportion of family medicine trainees pursuing extended training almost doubled during the study period, going from 10.9% in 1995 to 21.1% in 2013. Men and Canadian medical graduates were more likely to take extended family medicine training. Among the 5 most recent family medicine exit cohorts (from 2009 to 2013), 25.9% of men completed extended training programs compared with 18.3% of women, and 23.1% of Canadian medical graduates completed extended training compared with 13.6% of international medical graduates. Family medicine programs vary substantially with respect to the proportion of their trainees who undertake extended training, ranging from a low of 12.3% to a high of 35.1% among trainees exiting from 2011 to 2013. Conclusion New initiatives, such as the Triple C Competency-based Curriculum, CanMEDS–Family Medicine, and Certificates of Added Competence, have emerged as part of family medicine education and credentialing. In acknowledgment of the potential effect of these initiatives, it is important that future research examine how pedagogic change and, in particular, extended training shapes the care family physicians offer their patients. As part of that research it will be important to measure the breadth and uptake of

  3. Endogenous viral elements in animal genomes.

    Aris Katzourakis


    Full Text Available Integration into the nuclear genome of germ line cells can lead to vertical inheritance of retroviral genes as host alleles. For other viruses, germ line integration has only rarely been documented. Nonetheless, we identified endogenous viral elements (EVEs derived from ten non-retroviral families by systematic in silico screening of animal genomes, including the first endogenous representatives of double-stranded RNA, reverse-transcribing DNA, and segmented RNA viruses, and the first endogenous DNA viruses in mammalian genomes. Phylogenetic and genomic analysis of EVEs across multiple host species revealed novel information about the origin and evolution of diverse virus groups. Furthermore, several of the elements identified here encode intact open reading frames or are expressed as mRNA. For one element in the primate lineage, we provide statistically robust evidence for exaptation. Our findings establish that genetic material derived from all known viral genome types and replication strategies can enter the animal germ line, greatly broadening the scope of paleovirological studies and indicating a more significant evolutionary role for gene flow from virus to animal genomes than has previously been recognized.

  4. Molecular genetics and epigenetics of CACTA elements

    Fedoroff, Nina V.


    The CACTA transposons, so named for a highly conserved motif at element ends, comprise one of the most abundant superfamilies of Class 2 (cut-and-paste) plant transposons. CACTA transposons characteristically include subterminal sequences of several hundred nucleotides containing closely spaced direct and inverted repeats of a short, conserved sequence of 14-15 bp. The Supressor-mutator (Spm) transposon, identified and subjected to detailed genetic analysis by Barbara McClintock, remains the paradigmatic element of the CACTA family. The Spm transposon encodes two proteins required for transposition, the transposase (TnpD) and a regulatory protein (TnpA) that binds to the subterminal repeats. Spm expression is subject to both genetic and epigenetic regulation. The Spm-encoded TnpA serves as an activator of the epigenetically inactivated, methylated Spm, stimulating both transient and heritable activation of the transposon. TnpA also serves as a negative regulator of the demethylated active element promoter and is required, in addition to the TnpD, for transposition. © Springer Science+Business Media, New York 2013.

  5. The Chemistry of Superheavy Elements

    Schädel, M


    The chemistry of transactinide or superheavy elements has reached element 108. Preparations are under way to leap to element 112 and beyond. The current status of this atom-at-a-time chemical research and its future perspectives are reviewed from an experimental point of view together with some of the interesting results from n -rich nuclides near and at the N=162 neutron shell. Experimental techniques and important results enlightening typical chemical properties of elements 104 through 108 are presented in an exemplary way. From the results of these experiments it is justified to place these elements in the Periodic Table of the Elements in to groups 4 through 8, respectively. However, mainly due to the influence of relativistic effects, it is no longer possible to deduce detailed chemical properties of these superheavy elements simply from this position.

  6. Transplutonium elements - a literature survey

    Sivaramakrishnan, C.K.; Jadhav, A.V.


    The report surveys reported work on the discovery of transplutonium elements and their production through various methods like bombardment of heavy elements with charged ions, successive neutron captures on heavy elements in reactors and multiple neutron captures by heavy elements during nuclear explosions. Estimated yields of transplutonium elements in special targets irradiated in reactors, and also as byproducts from spent power reactor fuels are quoted. Various chemical procedures adopted for recovery of these elements from irradiated target and also from power reactor fuel reprocessing streams are described. A brief survey of shielded facilities available at various centres for transplutonium programmes is also included. Major uses of some of these heavy elements are described. (author)

  8. Advancing family psychology.

    Fiese, Barbara H


    To realize the broad and complex nature of the field of family psychology, I have slightly revised the mission statement of the Journal of Family Psychology (JFP) to capture contemporary scholarship in family psychology and to advance systems perspectives in this top-tier scientific journal. Over the next 6 years, I hope that authors will consider JFP as an outlet for their best work in the following areas: (1) JFP addresses societal challenges faced by families today; (2) JFP publishes important studies on what makes couple and family relationships work; (3) JFP is a leader in publishing reports that use cutting-edge sophisticated approaches to research design and data analysis; and (4) JFP imparts knowledge about effective therapy and prevention programs relevant to couples and families. The journal is also expanding its publication rate to eight issues per year. (c) 2016 APA, all rights reserved).

  9. Sharing family and household:

    Winther, Ida Wentzel

    Keynote: Family relationships are normatively assumed to be characterized by ‘sharing’, such as living together in the same home, occupying the same place, sharing stuff, blood and biology, spending special and ordinary time together, and consequently creating shared biographical experiences....... In that way, families are thrown into togetherness. At the same time, we see families in varying forms where 'sharing' is lived and contested differently. In Denmark, many children live in nuclear families, and many live in different variations of more than one household. For those who share household...... and family, 'sharing' will be a basic condition. No matter what, they should share life circumstances, more stories, more places and spaces, more households families with both kin and non-kin. This keynote addresses the particular of children’s experiences of living apart and/or living together in sharing...

Walker and Avante's method for concept analysis and the stages of the integrative review process, with a selection of publications in the PubMed, Cinahl and Lilacs databases focusing on the family conference theme in the context of palliative care. the most cited antecedents were the presence of doubts and the need to define a care plan. Family reunion and working instrument were evidenced as attributes. With respect to consequents, to promote the effective communication and to establish a plan of consensual action were the most remarkable elements. the scarcity of publications on the subject was observed, as well as and the limitation of the empirical studies to the space of intensive therapy. Thus, by analyzing the attributes, antecedents and consequents of the concept it was possible to follow their evolution and to show their efficacy and effectiveness as a therapeutic intervention.

  11. Familial Transient Global Amnesia

    R.Rhys Davies


    Full Text Available Following an episode of typical transient global amnesia (TGA, a female patient reported similar clinical attacks in 2 maternal aunts. Prior reports of familial TGA are few, and no previous account of affected relatives more distant than siblings or parents was discovered in a literature survey. The aetiology of familial TGA is unknown. A pathophysiological mechanism akin to that in migraine attacks, comorbidity reported in a number of the examples of familial TGA, is one possibility. The study of familial TGA cases might facilitate the understanding of TGA aetiology.

  13. Mantle End-Members: The Trace Element Perspective

    Willbold, M.; Stracke, A.; Hofmann, A. W.


    On the basis of their isotopic composition, ocean island basalts (OIB) have been classified into three to four end-members; HIMU with the most radiogenic Pb isotope ratios of OIB and Enriched Mantle 1 and 2 (EM1, EM2) with less radiogenic but variable Pb isotope and highly radiogenic Sr isotope signatures. It has also been argued that each of these isotopic families has common trace element characteristics that distinguish them from one another and so substantiated this classification. Here, we present new high-precision trace element data for samples from St. Helena, Tristan da Cunha and Gough in the Atlantic Ocean. The overall data-set is augmented by OIB data from the GEOROC database and includes data from all major isotopic families (HIMU: St. Helena, Mangaia, Tubuai, and Rururtu; EM1: Tristan da Cunha, Gough, Pitcairn; and EM2: Samoa, Marquesas, and Society). For each locality we use only islands defining the most extreme isotopic compositions. The entire data-set has been screened to exclude altered and highly differentiated samples. HIMU basalts have a very uniform trace element composition. Compared to HIMU-type basalts, EM-type basalts are enriched in Rb, Ba, and K, and depleted in U, Nb, and Ta, relative to La. Different EM-type OIBs from the same isotopic family (EM1 or EM2), have distinct trace element characteristics that can ultimately only be caused by different source compositions. For example, Ba/Th ratios in samples from both Tristan da Cunha (EM1) and Samoa (EM2) are similarly high (ca. 110) whereas Ba/Th ratios in samples from Pitcairn (EM1) and Society (EM2) samples are consistently lower (ca. 70). Thus on the basis of their trace element composition, EM-type OIB cannot be classified into EM1 and EM2 type basalts, nor can any other grouping be identified. The remarkably uniform isotopic and trace element composition of HIMU-type basalts suggests derivation from a single common source reservoir, most likely subduction-modified oceanic crust

  14. Semantic test of a technology management model in family business

    Guillermo Jesús Larios


    Full Text Available This paper assembles family business conceptions from the innovation and technology management perspective, and tests them in the case of a Mexican sugarcane producer. Literature indicates that non-financial objectives, risk aversion and strong controls negatively influence family firms’ innovation outcomes. Based on semantic network analysis, we collected transversal information on the firm’s technology activities, innovation values and organizational flows, which allowed for the identification of an organizational management profile that shapes an innovation style. Although we acknowledge literature consistency in aspects such as family direct influence and control, or the importance of STI partnerships and external knowledge, our findings didn’t identify any concerns about losing control in parts of the family business. This research contributes to the understanding of technology management and organizational elements in an emerging economy’s family firm from a relational perspective. Implications for theory endorsement and characterization of family business innovation and technology management in developing countries are discussed.

  15. EAF optimal managing elements

    Ioana, A.; Constantin, N.; Dragna, E. C.


    Electric Arc Furnaces (EAF) is an important and complex aggregate. We present elements of EAF operating efficiency. The reliability of the EAF is mainly determined by electric circuit reliability and especially of the transformator of the furnace. This due to the fact that, in an electric steel plant, the objective „24 tapping/day” involves. Due to the complexity of the process, the EAF operation needs a computer usage and, in his componence, it must have two independent calculation units (UC1) and (UC2). Based on these two input sets (Σi1) and ((Σi2), the calculation unit (UC1) builds the general operation procedure based on mathematical methods. For that purpose, there are used the results of the 5 mathematical methods: the mathematical model to write-off the function objective (M.F.O.); the mathematical model of calculating the charge (M.C.C.); the mathematical model of conducting the effective melt (M.C.M.); the mathematical model of reheating the charge (M.R.C.); the mathematical model of blasting the reactive dusts (M.B.R.D.).

  16. Nuclear fuel element

    Armijo, J.S.


    A nuclear fuel element for use in the core of a nuclear reactor is disclosed which has a composite cladding having a substrate, a metal barrier metallurgically bonded to the inside surface of the substrate and an inner layer metallurgically bonded to the inside surface of the metal barrier. In this composite cladding, the inner layer and the metal barrier shield the substrate from any impurities or fission products from the nuclear fuel material held within the composite cladding. The metal barrier forms about 1 to about 4 percent of the thickness of the cladding and is comprised of a metal selected from the group consisting of niobium, aluminum, copper, nickel, stainless steel, and iron. The inner layer and then the metal barrier serve as reaction sites for volatile impurities and fission products and protect the substrate from contact and reaction with such impurities and fission products. The substrate and the inner layer of the composite cladding are selected from conventional cladding materials and preferably are a zirconium alloy. Also in a preferred embodiment the substrate and the inner layer are comprised of the same material, preferably a zirconium alloy. 19 claims, 2 figures

  17. Neutron absorbing element

    Kasai, Shigeo.


    The present invention concerns a neutron absorbing element of a neutron shielding member used for an LMFBR type reactor. The inside of a fuel can sealed at both of the upper and the lower ends thereof with plugs is partitioned into an upper and a lower chambers by an intermediate plug. A discharging hole is disposed at the upper end plug, which is in communication with the outside. A communication tube is disposed at the intermediate end plug and it is in communication with the lower chamber containing B 4 C pellets. A cylindrical support member having three porous plugs connected in series is disposed at the lower surface of the discharging hole provided at the upper end plug. Further, the end of the discharging hole is sealed with high temperature solder and He atmosphere is present at the inside of the fuel can. With such a constitution, the supporting differential pressure of the porous plugs can be made greater while discharging He gases generated from B 4 C to the outside. Further, the porous plugs can be surely wetted by coolants. Accordingly, it is possible to increase life time and shorten the size. (I.N.)

The electron paramagnetic resonance spectrum of 253 Es 2+ was observed in the cubic monocrystal hosts BaF 2 and SrCl 2

  19. Chemistry of the superheavy elements.

    Schädel, Matthias


    The quest for superheavy elements (SHEs) is driven by the desire to find and explore one of the extreme limits of existence of matter. These elements exist solely due to their nuclear shell stabilization. All 15 presently 'known' SHEs (11 are officially 'discovered' and named) up to element 118 are short-lived and are man-made atom-at-a-time in heavy ion induced nuclear reactions. They are identical to the transactinide elements located in the seventh period of the periodic table beginning with rutherfordium (element 104), dubnium (element 105) and seaborgium (element 106) in groups 4, 5 and 6, respectively. Their chemical properties are often surprising and unexpected from simple extrapolations. After hassium (element 108), chemistry has now reached copernicium (element 112) and flerovium (element 114). For the later ones, the focus is on questions of their metallic or possibly noble gas-like character originating from interplay of most pronounced relativistic effects and electron-shell effects. SHEs provide unique opportunities to get insights into the influence of strong relativistic effects on the atomic electrons and to probe 'relativistically' influenced chemical properties and the architecture of the periodic table at its farthest reach. In addition, they establish a test bench to challenge the validity and predictive power of modern fully relativistic quantum chemical models. © 2015 The Author(s) Published by the Royal Society.

  20. Dynamical properties of the Watsonia asteroid family

    Tsirvoulis, G.; Novakovic, B.; Knezevic, Z.; Cellino, A.


    Introduction: In recent years, a rare class of asteroids has been discovered [1], with its distinguishing characteristic being the anomalous polarimetric properties of its members. Named Barbarians, after (234) Barbara, the prototype of the class, these asteroids show negative polarization at unusually high phase-angles compared to normal asteroids. Motivated by the fact that some of the few discovered Barbarians seemed to be related to the Watsonia asteroid family, Cellino et al. [2] performed a search for more Barbarians among its members. A positive result of this search led to the conclusion that Watsonia is indeed an important repository of Barbarian asteroids. Based on these findings, we decided to analyze this family in detail. Basic information: According to available data, Watsonia is an L-type asteroid family, located in the middle of the main asteroid belt (2.68 < a_{p} < 2.82 au), with low to moderate orbital eccentricities (0.1 < e_{p} < 0.15) and relatively high inclinations (16.5^{o} < i_{p} < 18^{o}). Methodology: The first step in our study is to derive a reliable list of Watsonia family members. To that purpose, we first calculate the synthetic proper elements [3] of an extended catalogue including numbered, as well as multi and single opposition asteroids, in a wide region around the family. To this catalogue we apply the Hierarchical Clustering Method (HCM)[4] to determine the membership of the family, coinciding with the requirement that all confirmed neighboring Barbarians are included (see figure). To detect potential interlopers and refine the membership list, additional data such as the SDSS colors and WISE albedos are used. Moreover, we identify all relevant resonances and analyze the dynamical characteristics of the region occupied by the family. Then we estimate the age of the family, and finally, we perform numerical integrations of test particles to investigate possible dynamical links to other known Barbarians and to the near

  1. Characterization of paralogous protein families in rice

    Zhu Wei


    Full Text Available Abstract Background High gene numbers in plant genomes reflect polyploidy and major gene duplication events. Oryza sativa, cultivated rice, is a diploid monocotyledonous species with a ~390 Mb genome that has undergone segmental duplication of a substantial portion of its genome. This, coupled with other genetic events such as tandem duplications, has resulted in a substantial number of its genes, and resulting proteins, occurring in paralogous families. Results Using a computational pipeline that utilizes Pfam and novel protein domains, we characterized paralogous families in rice and compared these with paralogous families in the model dicotyledonous diploid species, Arabidopsis thaliana. Arabidopsis, which has undergone genome duplication as well, has a substantially smaller genome (~120 Mb and gene complement compared to rice. Overall, 53% and 68% of the non-transposable element-related rice and Arabidopsis proteins could be classified into paralogous protein families, respectively. Singleton and paralogous family genes differed substantially in their likelihood of encoding a protein of known or putative function; 26% and 66% of singleton genes compared to 73% and 96% of the paralogous family genes encode a known or putative protein in rice and Arabidopsis, respectively. Furthermore, a major skew in the distribution of specific gene function was observed; a total of 17 Gene Ontology categories in both rice and Arabidopsis were statistically significant in their differential distribution between paralogous family and singleton proteins. In contrast to mammalian organisms, we found that duplicated genes in rice and Arabidopsis tend to have more alternative splice forms. Using data from Massively Parallel Signature Sequencing, we show that a significant portion of the duplicated genes in rice show divergent expression although a correlation between sequence divergence and correlation of expression could be seen in very young genes. Conclusion

  3. SXT/R391 Integrative and Conjugative Elements (ICEs) Encode a Novel 'Trap-Door' Strategy for Mobile Element Escape.

    Ryan, Michael P; Armshaw, Patricia; Pembroke, J Tony


    Integrative conjugative elements (ICEs) are a class of bacterial mobile elements that have the ability to mediate their own integration, excision, and transfer from one host genome to another by a mechanism of site-specific recombination, self-circularisation, and conjugative transfer. Members of the SXT/R391 ICE family of enterobacterial mobile genetic elements display an unusual UV-inducible sensitization function which results in stress induced killing of bacterial cells harboring the ICE. This sensitization has been shown to be associated with a stress induced overexpression of a mobile element encoded conjugative transfer gene, orf43, a traV homolog. This results in cell lysis and release of a circular form of the ICE. Induction of this novel system may allow transfer of an ICE, enhancing its survival potential under conditions not conducive to conjugative transfer.

  5. Éléments pour une analyse de la fraternité d’accueil dans un contexte de circulation des enfants Elements for an Analysis of Host Foster Families in a Context of Circulation of Children. An Illustration from the ‘île de La Réunion’

    Didier Le Gall


    Full Text Available Si la famille d’accueil apparaît bien comme un dispositif de protection de l’enfance, elle peut être aussi appréhendée comme une forme particulière de recomposition familiale : les enfants placés maintiennent des liens avec leur famille d’origine et tissent des liens avec l’assistante maternelle, son conjoint et ses enfants. Cette manière de “faire famille” diffère des recompositions à la suite d’une rupture d’union féconde, puisque ce sont des enfants qui s’adjoignent à une autre famille, et non un beau-parent. Il n’en reste pas moins que les enfants placés se trouvent, vis-à-vis des enfants de la famille d’accueil, dans une situation qui s’apparente à celle des quasi-frères et sœurs des familles recomposées en ce sens qu’ils ne partagent pas de sang commun. Il est dès lors possible d’analyser les liens qu’ils peuvent tisser comme relevant du fraternel, ce d’autant plus qu’ils co-résident ensemble au quotidien, ce qui est rarement le cas des quasi-frères et sœurs. S’adossant aux travaux récents sur la pluriparentalité et la fraternité recomposée, l’auteur se propose de porter un autre regard sur le placement familial en privilégiant l’angle de la fraternité d’accueil, et ce, dans un contexte qui présente la particularité d’avoir une tradition de circulation des enfants : la société réunionnaise.If the host family indeed seems to be a protective device for children, it can also be understood as a particular form of family recomposition: the children placed there maintain ties with their family of origin and establish ties with the maternal assistant, her spouse and his children. This way “of forming a family” differs from recompositions following the breakup of a fecund union, since it is the children who are joined to another family, and not an in-law. Vis-à-vis the host family, it nonetheless remains true that with respect to the host family’s children, the

  13. Family intervention for schizophrenia.

    Pharoah, F M; Mari, J J; Streiner, D


    It has been showed that people with schizophrenia from families that express high levels of criticism, hostility, or over involvement, have more frequent relapses than people with similar problems from families that tend to be less expressive of their emotions. Psychosocial interventions designed to reduce these levels of expressed emotions within families now exist for mental health workers. These interventions are proposed as adjuncts rather than alternatives to drug treatments, and their main purpose is to decrease the stress within the family and also the rate of relapse. To estimate the effects of family psychosocial interventions in community settings for the care of those with schizophrenia or schizophrenia-like conditions compared to standard care. Electronic searches of the Cochrane Library (Issue 2, 1998), the Cochrane Schizophrenia Group's Register (June 1998), EMBASE (1981-1995) and MEDLINE (1966-1995) were undertaken and supplemented with reference searching of the identified literature. Randomised or quasi-randomised studies were selected if they focused on families of people with schizophrenia or schizoaffective disorder and compared community-orientated family-based psychosocial intervention of more than five sessions to standard care. Data were reliably extracted, and, where appropriate and possible, summated. Peto odds ratios (OR), their 95% confidence intervals (CI) and number needed to treat (NNT) were estimated. The reviewers assume that people who died or dropped out had no improvement and tested the sensitivity of the final results to this assumption. Family intervention may decrease the frequency of relapse (one year OR 0.57 CI 0.4-0.8, NNT 6.5 CI 4-14). The trend over time of this main finding is towards the null and some small but negative studies may not have been identified by the search. Family intervention may decrease hospitalisation and encourage compliance with medication but data are few and equivocal. Family intervention does not

  14. Analog elements for transuranic chemistries

    Weimer, W.C.


    The analytical technique for measuring trace concentrations of the analog rare earth elements has been refined for optimal detection. The technique has been used to determine the rare earth concentrations in a series of geological and biological materials, including samples harvested from controlled lysimeter investigations. These studies have demonstrated that any of the trivalent rare earth elements may be used as analog elements for the trivalent transuranics, americium and curium

  17. Negotiating Family Tracking

    Albrechtslund, Anders; Bøge, Ask Risom; Sonne Damkjær, Maja

    This presentation explores the question: What motivates the use of tracking technologies in families, and how does the use transform the relations between parent and child? The purpose is to investigate why tracking technologies are used in families and how these technologies potentially change...... the relation between parents and children. The use of tracking technologies in families implicate negotiations about the boundaries of trust and intimacy in parent-child relations which can lead to strategies of resistance or modification (Fotel and Thomsen, 2004; Rooney, 2010; Steeves and Jones, 2010......). In the presentation, we report from a qualitative study that focuses on intergenerational relations. The study draws on empirical data from workshops with Danish families as well as individual and group interviews. We aim to gain insights about the sharing habits and negotiations in intimate family relations...

  3. Family planning education.

    Hamburg, M V


    17 days were spent devoted to the effort of learning about China's educational approach to family planning in the hope of discovering how they are achieving their remarkable success in reducing population growth. As a member of the 1981 New York University/SIECUS Colloquim in China, it was necessary to rely on the translation provided by the excellent guides. Discussions were focused on questions prepared in advance about the topics that concerned the group. These observations, based on a short and limited exposure, cover the following areas: marriage and family planning policies; the family planning program; school programs; adult education; family planning workers; and unique aspects of the program. China has an official position on marriage and family planning that continues to undergo revisions. The new marriage law sets the minimum ages of marriage at 22 for men and 20 for women. Almost everyone marries, and an unmarried person over age 28 is a rarity. The family planning program in China is carried out by an extensive organizational network at national, provincial, and local government levels. Officials termed it a "propaganda campaign." Hospitals, clinics, and factories invariably displayed posters; a popular set of four presents the advantages of the 1 child family as follows: late marriage is best, for it allows more time to work and study; 1 child is best for the health of the mother; one gets free medical care for his/her child if a family has only 1 child; and there is more time to teach 1 child. The state operated television regularly explains the 1 child policy utilizing special films. According to 1 family planning official, "before marriage there is little sex." There are few abortions for unmarried women. Education about sex is for adults, for those persons who are about to be married. There is little if any sex education in schools. Sexual teaching is not generally acceptable, especially in the rural areas. By contrast, in Shanghai the physiology

  4. Rare-earth elements

    Van Gosen, Bradley S.; Verplanck, Philip L.; Seal, Robert R.; Long, Keith R.; Gambogi, Joseph; Schulz, Klaus J.; DeYoung,, John H.; Seal, Robert R.; Bradley, Dwight C.


    The rare-earth elements (REEs) are 15 elements that range in atomic number from 57 (lanthanum) to 71 (lutetium); they are commonly referred to as the “lanthanides.” Yttrium (atomic number 39) is also commonly regarded as an REE because it shares chemical and physical similarities and has affinities with the lanthanides. Although REEs are not rare in terms of average crustal abundance, the concentrated deposits of REEs are limited in number.Because of their unusual physical and chemical properties, the REEs have diverse defense, energy, industrial, and military technology applications. The glass industry is the leading consumer of REE raw materials, which are used for glass polishing and as additives that provide color and special optical properties to the glass. Lanthanum-based catalysts are used in petroleum refining, and cerium-based catalysts are used in automotive catalytic converters. The use of REEs in magnets is a rapidly increasing application. Neodymium-iron-boron magnets, which are the strongest known type of magnets, are used when space and weight are restrictions. Nickel-metal hydride batteries use anodes made of a lanthanum-based alloys.China, which has led the world production of REEs for decades, accounted for more than 90 percent of global production and supply, on average, during the past decade. Citing a need to retain its limited REE resources to meet domestic requirements as well as concerns about the environmental effects of mining, China began placing restrictions on the supply of REEs in 2010 through the imposition of quotas, licenses, and taxes. As a result, the global rare-earth industry has increased its stockpiling of REEs; explored for deposits outside of China; and promoted new efforts to conserve, recycle, and substitute for REEs. New mine production began at Mount Weld in Western Australia, and numerous other exploration and development projects noted in this chapter are ongoing throughout the world.The REE-bearing minerals are

  5. Gender and family stability


    Full Text Available The increasing trend of partnership disruption among families with children in recent decades has been accompanied by substantial changes in traditional gender roles in industrialized countries. Yet, relatively little is known about the effects of changing gender relations on family stability in the European context. In this paper, we study such gender influences at the familial and societal level in Sweden and Hungary between the mid-1960s and the early 1990s. We focus on the disruption of the first parental union (i.e. the union in which a couple's first child was born. Our analysis is based on data extracted from the Swedish and Hungarian Fertility and Family Surveys of 1992/93. We use the method of hazard regression. The results suggest (i that the establishment of the dual-earner family model influences family stability only if it is accompanied by some changes in traditional gender relations within the family, and (ii that women's and men's labor-market behavior have different effects in spite of the relatively long history of women's (also mothers' labor-force participation in both Sweden and Hungary.

  8. Short interspersed elements (SINEs) of the Geomyoidea superfamily rodents.

    Gogolevsky, Konstantin P; Kramerov, Dmitri A


    A new short interspersed element (SINE) was isolated from the genome of desert kangaroo rat (Dipodomys deserti) using single-primer PCR. This SINE consists of two monomers: the left monomer (IDL) resembles rodent ID element and other tRNAAla(CGC)-derived SINEs, whereas the right one (Geo) shows no similarity with known SINE sequences. PCR and hybridization analyses demonstrated that IDL-Geo SINE is restricted to the rodent superfamily Geomyoidea (families Geomyidea and Heteromyidea). Isolation and analysis of IDL-Geo from California pocket mouse (Chaetodipus californicus) and Botta's pocket gopher (Thomomys bottae) revealed some species-specific features of this SINE family. The structure and evolution of known dimeric SINEs are discussed.

  9. Rack for nuclear fuel elements

    Rubinstein, H.J.; Gordon, C.B.; Robison, A.; Clark, P.M.


    Disclosed is a rack for storing spent nuclear fuel elements in which a plurality of aligned rows of upright enclosures of generally square cross-sectional areas contain vertically disposed spent fuel elements. Each fuel element is supported at the lower end thereof by a respective support that rests on the floor of the spent fuel pool for a nuclear power plant. An open rack frame is employed as an upright support for the enclosures containing the spent fuel elements. Legs at the lower corners of the frame rest on the floor of the pool to support the frame. In one exemplary embodiment, the support for the fuel element is in the form of a base on which a fuel element rests and the base is supported by legs. In another exemplary embodiment, each fuel element is supported on the pool floor by a self-adjusting support in the form of a base on which a fuel element rests and the base rests on a ball or swivel joint for self-alignment. The lower four corners of the frame are supported by legs adjustable in height for leveling the frame. Each adjustable frame leg is in the form of a base resting on the pool floor and the base supports a threaded post. The threaded post adjustably engages a threaded column on which rests the lower end of the frame. 16 claims, 14 figures

  12. Fluid element in SAP IV

    Yilmaz, C.; Akkas, N.


    In previous studies a fluid element is incorporated in the widely used general purpose finite element program SAPIV. This type of problem is of interest in the design of nuclear components involving geometric complexities and nonlinearities. The elasticity matrix of a general-purpose finite element program is modified in such a way that it becomes possible to idealize fluid as a structural finite element with zero shear modulus and a given bulk modules. Using the modified version of SAPIV, several solid-fluid interactions problems are solved. The numerical solutions are compared with the available analytical solutions. They are shown to be in reasonable aggrement. It is also shown that by solving an exterior-fluid interaction problem, the pressure wave propagation in the acoustic medium can be solved with the same approach. In this study, two of the problem not studied in the previous work will be presented. These problems are namely the effects of the link elements used at solid-fluid interfaces and of the concentrated loads on the response of the fluid medium. Truss elements are used as the link elements. After these investigations, it is decided that general purpose finite element programs with slight modifications can be used in the safety analysis of nuclear reactor plants. By this procedure it is possible to handle two-dimensional plane strain and tridimensional axisymmetric problems of this type. (orig.)

  13. Chemical experiments with superheavy elements.

    Türler, Andreas


    Unnoticed by many chemists, the Periodic Table of the Elements has been extended significantly in the last couple of years and the 7th period has very recently been completed with eka-Rn (element 118) currently being the heaviest element whose synthesis has been reported. These 'superheavy' elements (also called transactinides with atomic number > or = 104 (Rf)) have been artificially synthesized in fusion reactions at accelerators in minute quantities of a few single atoms. In addition, all isotopes of the transactinide elements are radioactive and decay with rather short half-lives. Nevertheless, it has been possible in some cases to investigate experimentally chemical properties of transactinide elements and even synthesize simple compounds. The experimental investigation of superheavy elements is especially intriguing, since theoretical calculations predict significant deviations from periodic trends due to the influence of strong relativistic effects. In this contribution first experiments with hassium (Hs, atomic number 108), copernicium (Cn, atomic number 112) and element 114 (eka-Pb) are reviewed.

    Vokrouhlicky, David; Nesvorny, David; Bottke, William F.; Morbidelli, Alessandro


    There are currently more than 1000 multi-opposition objects known in the Cybele population, adjacent and exterior to the asteroid main belt, allowing a more detailed analysis than was previously possible. Searching for collisionally born clusters in this population, we find only one statistically robust case: a family of objects about (87) Sylvia. We use a numerical model to simulate the Sylvia family long-term evolution due to gravitational attraction from planets and thermal (Yarkovsky) effects and to explain its perturbed structure in the orbital element space. This allows us to conclude that the Sylvia family must be at least several hundreds of million years old, in agreement with evolutionary timescales of Sylvia's satellite system. We find it interesting that other large Cybele-zone asteroids with known satellites-(107) Camilla and (121) Hermione-do not have detectable families of collisional fragments about them (this is because we assume that binaries with large primary and small secondary components are necessarily impact generated). Our numerical simulations of synthetic clusters about these asteroids show they would suffer a substantial dynamical depletion by a combined effect of diffusion in numerous weak mean-motion resonances and Yarkovsky forces provided their age is close to ∼4 billion years. However, we also believe that a complete effacement of these two families requires an additional component, very likely due to resonance sweeping or other perturbing effects associated with the late Jupiter's inward migration. We thus propose that both Camilla and Hermione originally had their collisional families, as in the Sylvia case, but they lost them in an evolution that lasted a billion years. Their satellites are the only witnesses of these effaced families.

  16. IDEA and Family Involvement

    Mehmet Emin Öztürk


    Full Text Available Individuals with Disabilities Education Act (IDEA gives many rights to parents with special needs in terms of involvement and participation. Given the importance of family involvement in the special education process, and federal legislation that increasingly mandated and supported such involvement over time, considerable research has focused on the multiple ways that relationships between schools and families in the special education decision making process have played out. Educational professionals should create a positive climate for CLD families so that they feel more comfortable and therefore are able to participate more authentically and meaningfully.

  17. Families of vicious walkers

    Cardy, John; Katori, Makoto


    We consider a generalization of the vicious walker problem in which N random walkers in R d are grouped into p families. Using field-theoretic renormalization group methods we calculate the asymptotic behaviour of the probability that no pairs of walkers from different families have met up to time t. For d > 2, this is constant, but for d -α , which we compute to O(ε 2 ) in an expansion in ε = 2 - d. The second-order term depends on the ratios of the diffusivities of the different families. In two dimensions, we find a logarithmic decay (ln t) -α-bar and compute α-bar exactly

  18. [Family Climate, Parental Partner Relationships and Symptom Formation in Children - Mentalisation- Based Family Therapy for Childhood Headache].

    Hantel-Quitmann, Wolfgang; Weidtmann, Katja


    The emotional family climate is considered both an effective risk and protective factor for child development. Factors such as negative experiences parents made during their childhood or adolescence, which can reoccur as intergenerational transmission, a low partnership quality and a high level of conflict seem to be particularly relevant for the quality of the emotional family climate. Consequently, the relationship between partners, as the core relation within families, is particularly important for the family climate and subsequently for the development of the child. For this reason, problems in parent relationships should receive special attention in family therapeutic interventions. Mentalisation-based family therapy (MBF-T) offers promising approaches in this context. The key principles of mentalisation are introduced and the links between family and mentalisation are presented, followed by information on the history, objectives and the procedures of MBF-T. A case study of a family therapy, in which a child suffers from chronic headache, illustrates the connection and interrelation between family climate, family conflicts and the parental relationship, and it will further show the importance of mentalisation-based elements for therapeutic treatments.

  19. Trace elements in human milk

    Parr, R M [International Atomic Energy Agency, Vienna (Austria). Div. of Life Sciences


    Trace elements are those elements having a concentration lower than 10 ppm in body fluids or tissues. A total of 24 elements, both trace and minor elements, present in human milk have been analysed in this study, employing neutron activation analysis and absorption spectroscopy. The analyses have been carried out collaboratively by several different laboratories and the Agency which has also served as a coordinating centre. Although the evaluation of the results, altogether 8500 separate values, is still in progress, enough evidence is already available, however, to show some very interesting differences between different study areas and, in some cases, between different socio-economic groups within a single country. The main value of these data will probably be to throw new light on the nutritional requirements of young babies for trace elements.

  3. Family medical leave as a resilience resource for family caregivers.

    Swanke, Jayme; Zeman, Laura Dreuth


    Case managers mobilize family networks to care for patients. Family medical leave can be a resource for case managers who seek to enhance resilience among family caregivers. The Family Medical Leave Act, passed in 1993, was the first U.S. policy to regulate employee leaves from work for family care purposes (29 CFR 825.102). This policy offers family caregivers increased flexibility and equality. Current and emerging policies also can reduce financial strain. The discussion examines how case managers can integrate family medical leave into best-practice models to support patients and family caregivers.

  5. Familial polycystic ovarian disease.

    Givens, J R


    Emphasis is placed on the heterogeneity of the phenotypic presentation of PCOD. It is the common expression of an unknown number of disorders and thus is a sign and not a specific diagnosis. Two essential features are arrested follicular maturation and atresia of follicles. Normal folliculogenesis is described, emphasizing that a large number of areas could be subject to derangement causing PCOD. Any interference of the finely balanced sequence of events can lead to PCOD. The genetic defect causing familial PCOD is unknown and the initiating event remains undefined. Three families are described that illustrate four features of familial PCOD. A number of associated disorders such as diabetes, hyperinsulinemia, obesity, and hypertension are described. The potential importance of agents that modulate the LH and FSH activity that may cause PCOD is emphasized. The theoretic means by which similar male and female gonadal abnormalities may be coupled in families through growth factors EGF and alpha TGF are presented.

  12. Status and interrelationship of toenail elements in Pacific children.

    Karatela, Shamshad; Ward, Neil I; Zeng, Irene Suilan; Paterson, Janis


    Elemental deficiencies or in excess effects growth and development. Pacific population are at a disadvantage due to food insecurity as compared to New Zealand European households. This study aims to evaluate the status and interrelationship of elements (essential, non-essential and toxic) in nine-year-old Pacific children who were part of the Pacific Island Families Study living in New Zealand. This observational study included 278 eligible nine-year-old children. Essential elements (including calcium, chromium, cobalt, copper, iodine, iron, magnesium, manganese, selenium, zinc, molybdenum), non-essential and toxic elements (arsenic, aluminum, antimony, boron, cadmium, lead, mercury, nickel,) were determined in toenails and after acid digestion, analysed using inductively coupled plasma mass spectrometry. Principal component analysis and multivariate analysis of covariance was used to identify differences in the groups of elements and the inter-correlations between elements. The mean calcium (868μg/g Ca), selenium (0.35μg/g Se) and zinc (129μg/g Zn) concentrations were lower while the mean cadmium (0.21μg/g Cd) lead (0.86μg/g Pb) and mercury (0.72μg/g Hg) concentrations were higher than the optimal health requirements. Ethnic differences in relation to toenail elemental concentrations were observed for aluminium and iron. Gender differences were observed for aluminium, antimony, arsenic and lead. Selenium and molybdenum were inversely associated with mercury. Manganese, zinc and calcium were positively associated. This research contributes to the understanding of the elemental concentrations for Pacific children by using tissue samples from toenails, which improves the completeness of sampling than other tissues and provides a longer exposure time frame. The study also reports several inter-correlations between essential, non-essential and toxic elements in Pacific Island population. Copyright © 2017 Elsevier GmbH. All rights reserved.

  14. Family support and family-centered care in the neonatal intensive care unit: origins, advances, impact.

    Gooding, Judith S; Cooper, Liza G; Blaine, Arianna I; Franck, Linda S; Howse, Jennifer L; Berns, Scott D


    Family-centered care (FCC) has been increasingly emphasized as an important and necessary element of neonatal intensive care. FCC is conceptualized as a philosophy with a set of guiding principles, as well as a cohort of programs, services, and practices that many hospitals have embraced. Several factors drive the pressing need for family-centered care and support of families of infants in NICUs, including the increase in the number of infants in NICUs; growth in diversity of the population and their concurrent needs; identification of parental and familial stress and lack of parenting confidence; and gaps in support for families, as identified by parents and NICU staff. We explore the origins of and advances in FCC in the NICU and identify various delivery methods and aspects of FCC and family support in the NICU. We examine the research and available evidence supporting FCC in the NICU and offer recommendations for increased dissemination and for future study. Copyright © 2011 Elsevier Inc.

    The role of women in family businesses is explored in the paper. Although recognized as generally very important players, the role of women is often defined as invisible in business decision-making, supportive in men’s traditional business domains and only rarelyadequately recognized and rewarded. The paper explores possible differences in the views of men and women who manage small family firms. Their attitudes opposing the traditional business roles ofwomen, different views on managerial, o...

  16. Family employees and absenteeism

    Laszlo Goerke; Jörn Block; Jose Maria Millan; Concepcion Roman


    Work effort varies greatly across employees, as evidenced by substantial differences in absence rates. Moreover, absenteeism causes sizeable output losses. Using data from the European Community Household Panel (ECHP), this paper investigates absence behavior of family employees, i.e. workers who are employed in enterprises owned by a relative. Our estimates indicate that being a family employee instead of a regular employee in the private sector significantly reduces both the probability and...

  17. The tubby family proteins

    Mukhopadhyay, Saikat; Jackson, Peter K


    The tubby mouse shows a tripartite syndrome characterized by maturity-onset obesity, blindness and deafness. The causative gene Tub is the founding member of a family of related proteins present throughout the animal and plant kingdoms, each characterized by a signature carboxy-terminal tubby domain. This domain consists of a β barrel enclosing a central α helix and binds selectively to specific membrane phosphoinositides. The vertebrate family of tubby-like proteins (TULPs) includes the foun...

  20. Platinum-group elements

    Zientek, Michael L.; Loferski, Patricia J.; Parks, Heather L.; Schulte, Ruth F.; Seal, Robert R.; Schulz, Klaus J.; DeYoung,, John H.; Seal, Robert R.; Bradley, Dwight C.


    The platinum-group elements (PGEs)—platinum, palladium, rhodium, ruthenium, iridium, and osmium—are metals that have similar physical and chemical properties and tend to occur together in nature. PGEs are indispensable to many industrial applications but are mined in only a few places. The availability and accessibility of PGEs could be disrupted by economic, environmental, political, and social events. The United States net import reliance as a percentage of apparent consumption is about 90 percent.PGEs have many industrial applications. They are used in catalytic converters to reduce carbon monoxide, hydrocarbon, and nitrous oxide emissions in automobile exhaust. The chemical industry requires platinum or platinum-rhodium alloys to manufacture nitric oxide, which is the raw material used to manufacture explosives, fertilizers, and nitric acid. In the petrochemical industry, platinum-supported catalysts are needed to refine crude oil and to produce aromatic compounds and high-octane gasoline. Alloys of PGEs are exceptionally hard and durable, making them the best known coating for industrial crucibles used in the manufacture of chemicals and synthetic materials. PGEs are used by the glass manufacturing industry in the production of fiberglass and flat-panel and liquid crystal displays. In the electronics industry, PGEs are used in computer hard disks, hybridized integrated circuits, and multilayer ceramic capacitors.Aside from their industrial applications, PGEs are used in such other fields as health, consumer goods, and finance. Platinum, for example, is used in medical implants, such as pacemakers, and PGEs are used in cancer-fighting drugs. Platinum alloys are an ideal choice for jewelry because of their white color, strength, and resistance to tarnish. Platinum, palladium, and rhodium in the form of coins and bars are also used as investment commodities, and various financial instruments based on the value of these PGEs are traded on major exchanges

  1. [Family, Suicide and Mourning].

    Garciandía Imaz, José Antonio


    Death is an event that always breaks into family life in a surprising way. Of all the deaths, suicide is the one which more strongly questions the functionality of a family and increases the risk of difficulties in the mourning process. Families in which a suicide has occurred are exposed to a greater possibility of disintegration, disorganization and pathological expressions in their members. To present a reduced and circumscribed narrative revision, restricted to examine the relationship between suicide and the mourning process in the family. The suicide of a loved one is an event that may contribute to pathological grief and mental dysfunctions in surviving relatives. Death in the family is a natural phenomenon. However, death by suicide is one of the phenomena that can generate more alterations in the structure and organization of the family, due to the difficulty related to the mourning process.

  2. Mandolin Family Instruments

    Cohen, David J.; Rossing, Thomas D.

    The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

  4. Families and educational systems in sub-Saharan Africa

    Miquel Reynés Ramón


    Full Text Available Studies and analysis of African educational systems’ performance do not pay much attention to the role of families; to the value they give to school and to how this may affect their decisions. By contrast, there are numerous researches focused on the most subjective elements of the relation between families and school: the attitudes, meanings and representations families, separately or as members of a social class or ethnic group, have of school. In this paper we will give five examples, drawn on sociological and anthropological studies, of different schooling practices and family representations of school. These are examples situated in different contexts and geographical areas that will allow us to appreciate the level of heterogeneity of family-school relationships in Africa and that may contribute to make us think otherwise the evolution of these educational systems.

  5. [Interactive patterns detection in family communication with adolescents].

    Gimeno Collado, Adelina; Anguera Argilaga, M Teresa; Berzosa Sanz, Amparo; Ramírez Ramírez, Luis


    Interactive patterns detection in family communication with adolescents. Nondistant communication is a relevant indicator for family functionality valuation. The goal of this study is to analyze this communication in order to identify specific kinds of leadership, interaction patterns and the relation between verbal and nonverbal elements in communication. The observational design exposed is an idiographic one, punctual and multidimensional, which uses field format as observation instrument. Participants were seven standardized families made up of both ancestors and an adolescent son or daughter. According to the family models analyzed, results show a predominantly democratic communication style in adults with recurrent support expressions. The sequential analysis incorporates only categories from the emitter point of view, and detects relevant sequences which show symmetric interaction between all three family members. Verbal and nonverbal channels provide complementary information. Depending on adolescents' gender different patterns in behaviour can be identified as well.

  6. New awareness campaign increases appeal of family planning.


    This article examines the impact of the campaign known as "Bringing New Marital and Reproductive Styles into Tens of Thousands of Households" on family planning in China. The awareness campaign, which started in October 1998, was established to increase the effectiveness of family planning and introduce progressive lifestyles among the population through an interactive and service-oriented approach focusing on the needs of human beings. The program emphasizes the following elements: 1) late marriage; 2) late childbirth; 3) fewer childbirth; 4) gender equality; 5) male participation in family planning; 6) dissemination of family planning and reproductive health knowledge; 7) healthier births and quality of education; 8) enhanced self-care capabilities; 9) higher quality of life; and 10) healthier lifestyles. A face-to-face approach was used to encourage public participation and increase the appeal of family planning programs to ordinary people. Efforts are also being made to expose rural residents to new ideas and lifestyles.

  7. Chemistry of the heaviest elements

    Hoffman, D.C.


    Studies of the chemical properties of the elements at the uppermost end of the periodic table are discussed. Some historical perspective is given, but major emphasis is on recent studies. Isotopes of these elements are short-lived and, therefore, must be studied near the site of production. They must be produced with charged-particle beams at accelerators rather than via neutron capture. The use of radioactive heavy actinide targets is often required and the number of atoms produced is so small that any chemistry to be performed must be done on an ''atom-at-a-time'' basis. Furthermore, a knowledge of their nuclear properties is required in order to identify and detect them. To date, both gas and aqueous phase properties of elements as heavy as element 104 (rutherfordium) and element 105 (hahnium) have been investigated, even though their longest-lived known isotopes have half-lives of only 65 and 35 seconds, respectively. The experimental results show that their chemical properties cannot be simply extrapolated from the known properties of their lighter homologs in the periodic table, emphasizing the importance of obtaining additional experimental information for the heaviest elements to compare with predictions and help assess the influence of relativistic effects. The feasibility of the extension of chemical studies to still heavier elements is also discussed. (orig.)

  8. "Not a Real Family": Microaggressions Directed toward LGBTQ Families.

    Haines, Kari M; Boyer, C Reyn; Giovanazzi, Casey; Galupo, M Paz


    The present study investigates microaggressions toward individuals in lesbian, gay, bisexual, transgender, and queer (LGBTQ) families. Microaggressions are subtle forms of discrimination experienced on a daily basis as verbal or behavioral slights against individuals in oppressed groups. LGBTQ microaggressions are often studied at an individual level and understood as being directed toward an individual based on perceived identity. The present study allows for an understanding of bias directed at the family system level. Participants included 46 adults who identified as being part of an LGBTQ family. Participants completed an online questionnaire and described their experiences of LGBTQ family microaggressions. Thematic analysis revealed that LGBTQ family microaggressions were salient to individuals across multiple family roles. Three specific themes emerged: family legitimacy, conflicts with family values, and gender violation within family. These findings highlight the way LGBTQ microaggressions are influenced by cultural notions of family and impact the family system.

    Sejnoha, R.; Manzer, A.M.; Surette, B.A.


    Unirradiated and irradiated CANDU fuel cladding was tested to compare the role of stress-corrosion cracking and of hydrogen in the development of fuel defects. The results of the tests are compared with information on fuel performance in-reactor. The role of hydriding (deuteriding) from the coolant and from the fuel element inside is discussed, and the control of 'hydrogen gas' content in the element is confirmed as essential for defect-free fuel performance. Finally, implications for fuel element design are discussed. (author)

    Tayler, R J


    The subject is discussed in relation to the composition of initially created matter and changes which have occurred during the life history of the universe, with particular reference to our galaxy and nearby galaxies. Headings are: observations of element abundances (stars, gas clouds in our own and nearby galaxies, hot gas in galaxy clusters, the solar system); the originally created matter (Big Bang theory and early nuclear reactions); processes changing observed composition (galactic evolution; nuclear fusion reactions in stellar interiors; chemical composition of a highly evolved massive star); supernovae (production of heavy elements); chemical evolution of the galaxy; production of very heavy elements (s process, r process).

    The specialists' group for fuel elements of the Kerntechnische Gesellschaft e.V. held a meeting on ''Increased Burnup of Fuel Elements'' on 9th and 10th of November 1982 at the GKSS Research Center Geesthacht. Most papers dealt with the problems of burnup increase of fuel elements for light water reactors with respect to fuel manufacturing, power plant operation and reprocessing. Review papers were given on the burnup limits for high temperature gas cooled reactors and sodium fast breeder reactors. The meeting ended with a presentation of the technical equipment of the hot laboratory of the GKSS and the programs which are in progress there. (orig.) [de

  14. Changing families, changing workplaces.

    Bianchi, Suzanne M


    American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force rate of mothers with children under age eighteen increased from 47.4 percent to 71.6 percent. Mothers today also return to work much sooner after the birth of a child than did mothers half a century ago. High divorce rates and a sharp rise in the share of births to unmarried mothers mean that more children are being raised by a single parent, usually their mother. Workplaces too have changed, observes Bianchi. Today's employees increasingly work nonstandard hours. The well-being of highly skilled workers and less-skilled workers has been diverging. For the former, work hours may be long, but income has soared. For lower-skill workers, the lack of "good jobs" disconnects fathers from family obligations. Men who cannot find work or have low earnings potential are much less likely to marry. For low-income women, many of whom are single parents, the work-family dilemma is how to care adequately for children and work enough hours to support them financially. Jobs for working-class and lower middle-class workers are relatively stable, except in economic downturns, but pay is low, and both parents must work full time to make ends meet. Family income is too high to qualify for government subsidized child care, but too low to afford high-quality care in the private market. These families struggle to have a reasonable family life and provide for their family's economic well-being. Bianchi concludes that the "work and family" problem has no one solution because it is not one problem. Some workers need more work and more money. Some need to take time off around the birth of a child

  15. Family Life and Developmental Idealism in Yazd, Iran

    Mohammad Jalal Abbasi-Shavazi


    Full Text Available BACKGROUND This paper is motivated by the theory that developmental idealism has been disseminated globally and has become an international force for family and demographic change. Developmental idealism is a set of cultural beliefs and values about development and how development relates to family and demographic behavior. It holds that modern societies are causal forces producing modern families, that modern families help to produce modern societies, and that modern family change is to be expected. OBJECTIVE We examine the extent to which developmental idealism has been disseminated in Iran. We also investigate predictors of the dissemination of developmental idealism. METHODS We use survey data collected in 2007 from a sample of women in Yazd, a city in Iran. We examine the distribution of developmental idealism in the sample and the multivariate predictors of developmental idealism. RESULTS We find considerable support for the expectation that many elements of developmental idealism have been widely disseminated. Statistically significant majorities associate development with particular family attributes, believe that development causes change in families, believe that fertility reductions and age-at-marriage increases help foster development, and perceive family trends in Iran headed toward modernity. As predicted, parental education, respondent education, and income affect adherence to developmental idealism. CONCLUSIONS Developmental idealism has been widely disseminated in Yazd, Iran and is related to social and demographic factors in predicted ways. COMMENTS Although our data come from only one city, we expect that developmental idealism has been widely distributed in Iran, with important implications for family and demographic behavior.

  16. Adaptive contact elements for three-dimensional fluid-structure interfaces

    Kulak, R.F.


    A finite element method is developed for treating the mechanics of contact between two deformable bodies which occurs, for example, at fluid-structure interfaces. The method uses a family of adaptive contact elements, which are based upon the penalty method, to handle all of the possible contact configurations that can occur between the discretized contacting bodies. The contact element's nodal connectivity is allowed to change during the computations in order to accommodate finite sliding. The infusion of these elements in the interface results in satisfying the force equilibrium condition during contact. The methodology has been implemented into the NEPTUNE code. Results are presented for an illustrative problem

  18. Interactions among tobacco sieve element occlusion (SEO) proteins.

    Jekat, Stephan B; Ernst, Antonia M; Zielonka, Sascia; Noll, Gundula A; Prüfer, Dirk


    Angiosperms transport their photoassimilates through sieve tubes, which comprise longitudinally-connected sieve elements. In dicots and also some monocots, the sieve elements contain parietal structural proteins known as phloem proteins or P-proteins. Following injury, P proteins disperse and accumulate as viscous plugs at the sieve plates to prevent the loss of valuable transport sugars. Tobacco (Nicotiana tabacum) P-proteins are multimeric complexes comprising subunits encoded by members of the SEO (sieve element occlusion) gene family. The existence of multiple subunits suggests that P-protein assembly involves interactions between SEO proteins, but this process is largely uncharacterized and it is unclear whether the different subunits perform unique roles or are redundant. We therefore extended our analysis of the tobacco P-proteins NtSEO1 and NtSEO2 to investigate potential interactions between them, and found that both proteins can form homomeric and heteromeric complexes in planta.

  19. Family First? The Costs and Benefits of Family Centrality for Adolescents with High-Conflict Families.

    Yuen, Cynthia X; Fuligni, Andrew J; Gonzales, Nancy; Telzer, Eva H


    Youth who do not identify with or value their families (i.e., low family centrality) are considered to be at risk for maladjustment. However, the current study investigated whether low family centrality may be adaptive in negative family contexts (i.e., high family conflict) because youth's self-worth should be less tied to the quality of their family relationships. Multilevel models using daily diaries and latent variable interactions using longitudinal questionnaires indicated that, among a sample of 428 Mexican American adolescents (49.8% male, M age  = 15.02 years), lower family centrality was generally detrimental to youth's well-being. However, for youth in adverse family environments, low family centrality ceased to function as a risk factor. The present findings suggest that family centrality values play a more nuanced role in youth well-being than previously believed, such that low family centrality may be an adaptive response to significant family challenges.

  20. Elemental balance in soy sauce

    Haruyama, Yoichi; Saito, Manabu; Yoshida, Koji.


    We have measured the elemental concentrations of soy sauce and its actual raw materials which are used in a certain soy sauce factory. In the present measurement, we measured de-fatted soybean, wheat and salt as raw materials and soy sauce and soy sauce waste as final products. Five kinds of elements, such as Mn, Fe, Cu, Zn and Br, were detected. We obtained elemental concentrations of them except for Mn in each materials. The measured elemental concentration in soy sauce agreed well each other with the calculated one within the experimental errors using the measured concentration in the raw materials and their weight in actual producing process. Contrary to our expectation, it was found that wheat contributes to soy sauce bromine concentration dominantly in the present case. (author)

  3. Nuclear reactor fuel element assemblies

    Krawiec, D.M.; Bevilacqua, F.


    The fuel elements of each fuel element group are separated from each other by means of a multitude of thin, intersecting plates in the from of grid strips. Flow deflectors near the surface of the fuel elements are used in order to make the coolant flow more turbulent. They are designed as vanes and arranged at a distance on the grid strips. Each deflector vane has two arms stretching in opposite directions, each one into a neighbouring channel. In outward direction, the deflector vanes are converging. The strips with the vanes can be put on the supporting grid of the fuel elements. The vane structure can be reinforced by providing distortions in the strip material near the vanes. (DG) [de

  4. Elemental ABAREX -- a user's manual

    Smith, A.B.


    ELEMENTAL ABAREX is an extended version of the spherical optical-statistical model code ABAREX, designed for the interpretation of neutron interactions with elemental targets consisting of up to ten isotopes. The contributions from each of the isotopes of the element are explicitly dealt with, and combined for comparison with the elemental observables. Calculations and statistical fitting of experimental data are considered. The code is written in FORTRAN-77 and arranged for use on the IBM-compatible personal computer (PC), but it should operate effectively on a number of other systems, particularly VAX/VMS and IBM work stations. Effort is taken to make the code user friendly. With this document a reasonably skilled individual should become fluent with the use of the code in a brief period of time

  5. The evolution of the elements

    Williams, P.M.


    It is believed that only the lightest elements, hydrogen and helium, were created during the 'Big Bang' origin of the Universe and that all heavier elements were synthesized by nuclear reactions in stars, the interstellar medium and possibly in 'little bangs' in the nuclei of galaxies. The composition of the interstellar medium has evolved through enrichment by processed material shed by evolving stars and the composition of the Solar System reflects that of the interstellar medium at the time of its formation. Differentiation processes during the evolution of the Solar System and individual planets account for the different compositions of the Sun and the planets. The measurement of the abundance distribution of the elements has become a very powerful tool in the elucidation of the evolution of the Solar System, stars and the Galaxy. This review attempts to trace the formation of the elements in stars and their subsequent evolution. (author)

  17. Who counts as family? Family typologies, family support, and family undermining among young adult gay and bisexual men.

    Soler, Jorge H; Caldwell, Cleopatra H; Córdova, David; Harper, Gary; Bauermeister, José A


    Gay and bisexual men may form chosen families in addition to or in place of families of origin. However, the characteristics of these diverse families remain largely unexamined in the quantitative literature. The purpose of this study was to develop a family typology based on responses from a racially and ethnically diverse sample of young adult gay and bisexual men (YGBM) recruited from the Detroit Metropolitan Area (N=350; 18-29 years old). To explore the role of family, we then examined family social support and social undermining in relation to YGBM psychological distress within different family types. A series of multivariate regressions were used to examine associations between family social support and social undermining with depression and anxiety outcomes. The majority (88%) of YGBM included family of origin in their definitions of family and 63% indicated having chosen families. Associations between family social processes and psychological outcomes varied by type of family, suggesting that family composition shapes how perceptions of support and undermining relate to experiencing symptoms of depression and anxiety. Chosen families play a prominent role in the lives of YGBM and should not be overlooked in family research. Findings also highlight the importance of examining co-occurring family social support and social stress processes to further address psychological distress symptoms among YGBM.

    Full Text Available Background. The number of elderly patients, i.e. people over 64 years, is growing. With longer life span the proportion of elderly people will be even higher. Elderly patients are a heterogeneous group of patients with considerable differences in health status, functional capacity, emotions, fears, beliefs and views.Health care of elderly patients in primary care is a responsibility of family doctors. One third of all family practice consultations are in the age group over 64. A consultation in the elderly is different from a consultation in younger patients. The consultation length in those patients is longer and the office visits of elderly are more frequent. If we want to deliver a quality care for the elderly, we have to care for them and manage their illness in psychological, physical, family and social context, which is a core stone of biopsychosocial model of medical practice. Besides medical knowledge and patient participation, all these elements make a foundation of the holistic approach. In elderly a special attention to their attitude towards aging, dying, loneliness and to the fears connected to those issues should be taken into account. Coordination with other services and with patients’ families is also necessary. Family physician is in the best position to recognise abuse, neglection or limitations in patient autonomy.We should be aiming to achieve a connection between the doctor and the patient through continuity between the doctor, the patient and his/her family. Good connection will make management of elderly patients more effective and the patients will accept and follow therapeutic plan.

  7. Family functioning in the families of psychiatric patients: a comparison with nonclinical families.

    Trangkasombat, Umaporn


    To examine family functioning in the families of psychiatric patients. Families of psychiatric patients and nonclinical families were compared. There were 60 families in each group. The instrument included a semistructured interview of family functioning and the Chulalongkorn Family Inventory (CFI), a self-report questionnaire designed to assess the perception of one's family. From the assessment by semistructured interview, 83.3% of psychiatric families and 45.0% of nonclinical families were found to be dysfunctional in at least one dimension. The difference was statistically significant (p dysfunctional dimensions in the psychiatric families was significantly higher than in the nonclinical control group, 3.5 +/- 1.9 and 0.98 +/- 1.5 respectively, p families were significantly lower than the control group, reflecting poor family functioning. The dysfunctions were mostly in the following dimensions: problem-solving, communication, affective responsiveness, affective involvement, and behavior control. Psychiatric families faced more psychosocial stressors and the average number of stressors was higher than the control families, 88.3% vs. 56.7% and 4.2 +/- 2.7 vs. 1.3 +/- 1.47 stressors respectively, p < 0.0001. Family functioning of psychiatric patients was less healthy than the nonclinical control. The present study underlined the significance of family assessment and family intervention in the comprehensive care of psychiatric patients.

  8. Attitudes toward family planning.

    Gille, H


    Many of the 135 countries participating in the 1974 UN World Population Conference were far from accepting the basic human right to decide freely and responsibly the number and spacing of their children and to have the information, education, and means to do so. Considerable progress has been made since then, and the number of developing countries that provide direct government support for family planning has increased to over 60%. Many have liberalized laws and regulations which restricted access to modern contraceptive methods, and a growing number provide family planning services within their health care programs. A few have recognized the practice of family planning as a constitutional right. In late 1983 at the Second African Population Conference, recognition of family as a human right was strongly contested by several governments, particularly those of West Africa. in developed countries most of the women at risk of unwanted pregnancy are using contraceptives. Of the major developing regions the highest use level is in Latin America, wherein most countries 1/3 to 1/2 of married women are users. Levels in Asian countries range from up to 10% in Afghanistan, Nepal, and Pakistan to up to 40% in the southeastern countries. China, a special case, now probably exceeds an overall use level of 2/3 of married women. Contraceptive use is lowest in Africa. There is room for improvement even among many of the successful family planning programs, as access to contraceptives usually is not sufficient to overcome limiting factors. To ensure the individual's free choice and strengthen the acceptability and practice of family planning, all available methods should be provided in service programs and inluded in information and education activities. Family planning programs should engage local community groups, including voluntary organizations, in all aspects of planning, management, and allocation of resources. At the government level a clear political commitment to family

  9. Chemistry of the transactinide elements

    Schaedel, M.


    The experimentally known chemical properties of the transactinide elements 104 and 105, and the experimental techniques used to study these properties on an atom-at-a-time base, are reviewed. The production of transactinides in heavy ion reactions and the specific aspects of chemical separations with single atoms is briefly discussed. The chemical properties of the first two transactinide elements are compared with the lighter element homologs in group 4 and 5 of the Periodic Table and with the expected behaviour obtained from most recent atomic and molecular calculations which take the increasingly strong relativistic effect into account. Elements 104 and 105 behave as transactinide elements and, in general, exhibit properties characteristic of their position in group 4 and 5 of the Periodic Table. However, surprising deviations of the chemical properties from expectations based on simple extrapolations have been observed. It is shown that the chemical properties of the heaviest elements cannot reliably be predicted by simple extrapolations. Prospects to extend our chemical knowledge at the top end of the Periodic Table are discussed. (orig.)

  10. Gender Stereotyping in Family

    Muhammad Hussain


    Full Text Available Gender stereotyping and gender role development is one of the debatable concerns to sociologists especially those who are interested in sociology of gender. This study attempts to investigate the role of family inculcating gender stereotyping in Pakhtun culture and its impact on gender role development conducted in public-sector universities of Malakand Division, Khyber Pakhtunkhwa province of Pakistan. The data were collected through in-depth interview method using interview guide as a tool of data collection. A sample size of 24 respondents consisting male and female students and teachers (8 samples from each university through purposive sampling technique was selected from three universities in the region, that is, University of Malakand, University of Swat, and Shaheed Benazir Bhutto University Sharingal (main campus. The collected information has been analyzed qualitatively where primary information has been linked with secondary data for further elaboration and attainment of grounded facts. The study reveals that gender stereotyping and gender role formation are sociocultural and relational constructs, which are developed and inculcated in the institutional network, social interaction, and social relationships especially in family. The study indicated that in family sphere, gender stereotyping and gender role formation are the outcome of gender socialization, differential familial environment, and parents’ differential role with children. The study recommends that gender-balanced familial environment, adopting the strategy of gender mainstreaming and positive role of media, can overcome gender stereotyping and reduce its impacts on gender and social role formation.

  11. Egypt boosts family planning.


    A $4 million Agency for International Development (AID) agreement was signed in Cairo September 30 which will help the Egyptian government increase family planning services. The project is in response to a request for up to $17 million of AID funds for family planning programs during the next 3 years. The funds will pay for: contract advisors to provide short-term in-country training of physicians, architectural and engineering services to renovate a hospital for family planning and obstetrics/gynecology training, and a field training site for family planning service providers. Some Egyptians will receive training in specialized areas in the U.S. and other countries. More than $1.5 million of the $4 million will finance local costs of goods and services required. In addition, it is anticipated that U.S.-owned local currencies will be obligated for direct support of U.S. technical personnel. Over the 3-year life of the project the $17 million from AID plus $664,000 of U.S.-owned local currency will cover 44% of the total costs of selected Egyptian family planning activities. The Egyptian government will contribute at least $18.4 million and the U.N. Fund for Population Activities and the International Bank for Reconstruction and Development will contribute $4.3 million.

  12. Family focused nursing education

    R. A. E. Thompson


    Full Text Available At the present time the majority of nurse education programmes are firmly tied to the perspectives of curative medicine within hospitals - they are disease and hospital oriented. This model, which indicates a 'sickness’ concept of nursing is entirely inappropriate if contemporary and future health care needs are to be met. The shift in education should be towards a health, family and whole person centered approach. The family is the most fundamental and dynamic unit in society with a profound influence upon its members. Besides performing a variety of other functions, the family has a central role in promoting and maintaining the health of its members. Because the family unit is the microcosm of society and accurately reflects the needs of society at large it is appropriate that this should be a key area of experience. Family attachments during training provide opportunities for close and committed contact with people in their everyday world and for learning what is really important to them.

  13. Designing Work, Family & Health Organizational Change Initiatives.

    Kossek, Ellen Ernst; Hammer, Leslie B; Kelly, Erin L; Moen, Phyllis


    For decades, leaders and scholars have been advocating change efforts to improve work-life relationships. Yet most initiatives have lacked rigor and not been developed using scientific principles. This has created an evidence gap for employer support of work and personal life as a win-win for productivity and employees' well-being. This paper examines the approach used by the U.S. Work Family Health Network (WFRN) to develop an innovative workplace intervention to improve employee and family health. The change initiative was designed to reduce organizationally based work-family conflict in two contrasting contexts representative of major segments of today's U.S. workforce: health care employees and informational technology professionals. The WFRN Intervention (called STAR) had three theoretically based change elements. They were: 1) increase job control over work time and schedule; 2) increase supervisor social support for family and job effectiveness; and 3) improve organizational culture and job design processes to foster results orientation. Seven practical lessons for developing work-life interventions emerged from this groundbreaking endeavor.

  14. The role of retrotransposons in gene family expansions: insights from the mouse Abp gene family.

    Janoušek, Václav; Karn, Robert C; Laukaitis, Christina M


    Retrotransposons have been suggested to provide a substrate for non-allelic homologous recombination (NAHR) and thereby promote gene family expansion. Their precise role, however, is controversial. Here we ask whether retrotransposons contributed to the recent expansions of the Androgen-binding protein (Abp) gene families that occurred independently in the mouse and rat genomes. Using dot plot analysis, we found that the most recent duplication in the Abp region of the mouse genome is flanked by L1Md_T elements. Analysis of the sequence of these elements revealed breakpoints that are the relicts of the recombination that caused the duplication, confirming that the duplication arose as a result of NAHR using L1 elements as substrates. L1 and ERVII retrotransposons are considerably denser in the Abp regions than in one Mb flanking regions, while other repeat types are depleted in the Abp regions compared to flanking regions. L1 retrotransposons preferentially accumulated in the Abp gene regions after lineage separation and roughly followed the pattern of Abp gene expansion. By contrast, the proportion of shared vs. lineage-specific ERVII repeats in the Abp region resembles the rest of the genome. We confirmed the role of L1 repeats in Abp gene duplication with the identification of recombinant L1Md_T elements at the edges of the most recent mouse Abp gene duplication. High densities of L1 and ERVII repeats were found in the Abp gene region with abrupt transitions at the region boundaries, suggesting that their higher densities are tightly associated with Abp gene duplication. We observed that the major accumulation of L1 elements occurred after the split of the mouse and rat lineages and that there is a striking overlap between the timing of L1 accumulation and expansion of the Abp gene family in the mouse genome. Establishing a link between the accumulation of L1 elements and the expansion of the Abp gene family and identification of an NAHR-related breakpoint in

  15. Conferences and Family Reunions

    Sarah Sutherland


    Full Text Available Professional associations and conferences have similarities with and differences from families and family reunions. This comparison can illustrate some ways professional associations can approach the integration of new members and the planning of conferences in order to facilitate membership development and leadership renewal. Unlike family reunions, professional conferences are not closed events that require a shared culture in order to fully participate; they are events that should show the constant change and development of practice that is representative of the profession – for both members and non-members. Some of the topics explored in the article are: making it easy for outsiders to contribute, considering the tastes of new members, making it easy to volunteer in a meaningful way, and remembering who the future of the organization is. These simple considerations will assist in opening professional associations to new participants and help them to maintain their relevance and vitality over time.

    Han, Won Jeong; Kim, Eun Kyung [Dankook Univ. School of Dentistry, Seoul (Korea, Republic of)


    Familial gigantiform cementoma is a rate fibro-cemento-osseous disease of the jaws which appears to be transmitted as an autosomal dominant trait with variable expressivity of the phenotype. A 7-year-old girl visited DKUDH complaining of the painless facial deformity. Clinically, significant facie-lingual expansion was observed at the left maxilla, left mandibular body and symphysis portion. Malposition of lower anterior teeth was found. Panoramic radiograph and CT scan showed the extensive expandile mixed lesion at maxilla and mandible. Bone scan revealed hot spot at the maxilla and left side of mandible. Histologic examination revealed moderately dense fibrous connective tissue with scattered masses resembling cementum. The patient's mother had a history of the mandibular resection due to benign tumor. Her younger brother had buccal expansion of right mandible. We report our finding of a family that has exhibited clinical, radiographic and histologic findings consistent with the familial gigantiform dementoma.

  19. Family environment patterns in families with bipolar children.

    Belardinelli, Cecilia; Hatch, John P; Olvera, Rene L; Fonseca, Manoela; Caetano, Sheila C; Nicoletti, Mark; Pliszka, Steven; Soares, Jair C


    We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Parents of bipolar children reported lower levels of family cohesion (pfamilies where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder.

  7. Incarceration in fragile families.

    Wildeman, Christopher; Western, Bruce


    Since the mid-1970s the U.S. imprisonment rate has increased roughly fivefold. As Christopher Wildeman and Bruce Western explain, the effects of this sea change in the imprisonment rate--commonly called mass imprisonment or the prison boom--have been concentrated among those most likely to form fragile families: poor and minority men with little schooling. Imprisonment diminishes the earnings of adult men, compromises their health, reduces familial resources, and contributes to family breakup. It also adds to the deficits of poor children, thus ensuring that the effects of imprisonment on inequality are transferred intergenerationally. Perversely, incarceration has its most corrosive effects on families whose fathers were involved in neither domestic violence nor violent crime before being imprisoned. Because having a parent go to prison is now so common for poor, minority children and so negatively affects them, the authors argue that mass imprisonment may increase future racial and class inequality--and may even lead to more crime in the long-term, thereby undoing any benefits of the prison boom. U.S. crime policy has thus, in the name of public safety, produced more vulnerable families and reduced the life chances of their children. Wildeman and Western advocate several policy reforms, such as limiting prison time for drug offenders and for parolees who violate the technical conditions of their parole, reconsidering sentence enhancements for repeat offenders, and expanding supports for prisoners and ex-prisoners. But Wildeman and Western argue that criminal justice reform alone will not solve the problems of school failure, joblessness, untreated addiction, and mental illness that pave the way to prison. In fact, focusing solely on criminal justice reforms would repeat the mistakes the nation made during the prison boom: trying to solve deep social problems with criminal justice policies. Addressing those broad problems, they say, requires a greater social

  8. New elements - approaching Z=114

    Hofmann, S.


    The search for new elements is part of the broader field of investigations of nuclei at the limits of stability. In two series of experiments at SHIP, six new elements (Z=107-112) were synthesized via fusion reactions using 1n-deexcitation channels and lead or bismuth targets. The isotopes were unambiguously identified by means of α-α correlations. Not fission, but alpha decay is the dominant decay mode. The collected decay data establish a means of comparison with theoretical data. This aids in the selection of appropriate models that describe the properties of known nuclei. Predictions based on these models are useful in the preparation of the next generation of experiments. Cross-sections decrease by two orders of magnitude from bohrium (Z=107) to element 112, for which a cross-section of 1 pb was measured. The development of intense beam currents and sensitive detection methods is essential for the production and identification of still heavier elements and new isotopes of already known elements, as well as the measurement of small α-, β- and fission-branching ratios. An equally sensitive set-up is needed for the measurement of excitation functions at low cross-sections. Based on our results, it is likely that the production of isotopes of element 114 close to the island of spherical super heavy elements (SHE) could be achieved by fusion reactions using 208 Pb targets. Systematic studies of the reaction cross-sections indicate that the transfer of nucleons is an important process for the initiation of fusion. The data allow for the fixing of a narrow energy window for the production of SHE using 1n-emission channels. (orig.)

  9. Family Resilience in the Military

    Meadows, Sarah O.; Beckett, Megan K.; Bowling, Kirby; Golinelli, Daniela; Fisher, Michael P.; Martin, Laurie T.; Meredith, Lisa S.; Osilla, Karen Chan


    Abstract Military life presents a variety of challenges to military families, including frequent separations and relocations as well as the risks that service members face during deployment; however, many families successfully navigate these challenges. Despite a recent emphasis on family resilience, the U.S. Department of Defense (DoD) does not have a standard and universally accepted definition of family resilience. A standard definition is a necessary for DoD to more effectively assess its efforts to sustain and improve family resilience. RAND authors reviewed the literature on family resilience and, in this study, recommend a definition that could be used DoD-wide. The authors also reviewed DoD policies related to family resilience, reviewed models that describe family resilience and identified key family resilience factors, and developed several recommendations for how family-resilience programs and policies could be managed across DoD.

  12. Finite element modeling of piezoelectric elements with complex electrode configuration

    Paradies, R; Schläpfer, B


    It is well known that the material properties of piezoelectric materials strongly depend on the state of polarization of the individual element. While an unpolarized material exhibits mechanically isotropic material properties in the absence of global piezoelectric capabilities, the piezoelectric material properties become transversally isotropic with respect to the polarization direction after polarization. Therefore, for evaluating piezoelectric elements the material properties, including the coupling between the mechanical and the electromechanical behavior, should be addressed correctly. This is of special importance for the micromechanical description of piezoelectric elements with interdigitated electrodes (IDEs). The best known representatives of this group are active fiber composites (AFCs), macro fiber composites (MFCs) and the radial field diaphragm (RFD), respectively. While the material properties are available for a piezoelectric wafer with a homogeneous polarization perpendicular to its plane as postulated in the so-called uniform field model (UFM), the same information is missing for piezoelectric elements with more complex electrode configurations like the above-mentioned ones with IDEs. This is due to the inhomogeneous field distribution which does not automatically allow for the correct assignment of the material, i.e. orientation and property. A variation of the material orientation as well as the material properties can be accomplished by including the polarization process of the piezoelectric transducer in the finite element (FE) simulation prior to the actual load case to be investigated. A corresponding procedure is presented which automatically assigns the piezoelectric material properties, e.g. elasticity matrix, permittivity, and charge vector, for finite element models (FEMs) describing piezoelectric transducers according to the electric field distribution (field orientation and strength) in the structure. A corresponding code has been

  13. Enhanced production of recombinant proteins with Corynebacterium glutamicum by deletion of insertion sequences (IS elements).

    Choi, Jae Woong; Yim, Sung Sun; Kim, Min Jeong; Jeong, Ki Jun


    In most bacteria, various jumping genetic elements including insertion sequences elements (IS elements) cause a variety of genetic rearrangements resulting in harmful effects such as genome and recombinant plasmid instability. The genetic stability of a plasmid in a host is critical for high-level production of recombinant proteins, and in this regard, the development of an IS element-free strain could be a useful strategy for the enhanced production of recombinant proteins. Corynebacterium glutamicum, which is a workhorse in the industrial-scale production of various biomolecules including recombinant proteins, also has several IS elements, and it is necessary to identify the critical IS elements and to develop IS element deleted strain. From the cultivation of C. glutamicum harboring a plasmid for green fluorescent protein (GFP) gene expression, non-fluorescent clones were isolated by FACS (fluorescent activated cell sorting). All the isolated clones had insertions of IS elements in the GFP coding region, and two major IS elements (ISCg1 and ISCg2 families) were identified. By co-cultivating cells harboring either the isolated IS element-inserted plasmid or intact plasmid, it was clearly confirmed that cells harboring the IS element-inserted plasmids became dominant during the cultivation due to their growth advantage over cells containing intact plasmids, which can cause a significant reduction in recombinant protein production during cultivation. To minimize the harmful effects of IS elements on the expression of heterologous genes in C. glutamicum, two IS element free C. glutamicum strains were developed in which each major IS element was deleted, and enhanced productivity in the engineered C. glutamicum strain was successfully demonstrated with three models: GFP, poly(3-hydroxybutyrate) [P(3HB)] and γ-aminobutyrate (GABA). Our findings clearly indicate that the hopping of IS elements could be detrimental to the production of recombinant proteins in C

  15. Brain trace elements and aging

    Hebbrecht, Geert; Maenhaut, Willy; Reuck, Jacques de


    Degenerative mechanisms involved in the aging process of the brain are to a certain extent counteracted by repair mechanisms. In both degenerative and recovery processes, trace elements are involved. The present study focused on the role of two minor (i.e., K and Ca) and six trace elements (i.e., Mn, Fe, Cu, Zn, Se and Rb) in the aging process. The elements were determined by PIXE in cerebral cortex and white matter, basal ganglia, brainstem and cerebellar cortex of 18 postmortem human brains, from persons without a history of neurologic or psychiatric disease who deceased between the age of 7 and 79. This age range allowed us to study the relationship between elemental concentrations and age. The most prominent findings were a concentration decrease for K and Rb and a concentration increase for the elements Ca, Fe, Zn and Se. The study supports recent findings that Ca and Fe are involved in brain degenerative processes initiated by oxygen free radicals, whereas Zn and Se are involved in immunological reactions counteracting the aging process

  16. Another way to teach family: family nursing game

    Carla Sílvia Neves da Nova Fernandes


    Full Text Available Current paper describes the application of an innovative strategy to teach family, within a hospital context, by sensitizing nurses on the family subject through the use of a game. Given the hospitalization of a relative, the family faces changes in its dynamics caused by the crisis it is exposed to. It is the relevance for including the family within the care process. Since nurses are expected to assume a key role for which they need specific competence to intervene in families when experiencing an eventual crisis. The in-service education becomes a strategy of generating new skills and enhances human capital to improve the quality of nursing care. Considering the importance of including family in the care context, a playful tool called Family Nursing Game has been invented for teaching the family, especially by passing a model of family intervention. The strategy is based on the belief of the existence of relationship between game and learning.

  17. Family interactions in adoptive compared to nonadoptive families.

    Rueter, Martha A; Keyes, Margaret A; Iacono, William G; McGue, Matt


    Despite the large and growing numbers of adoptive families, little research describes interactions in families with adopted adolescents. Yet, adopted adolescents' increased risk for adjustment problems, combined with the association between family interactions and adolescent adjustment in nonadoptive families, raises questions about differences in adoptive and nonadoptive family interactions. We compared observed and self-reported family interactions between 284 adoptive and 208 nonadoptive families and within 123 families with 1 adopted and 1 nonadopted adolescent. Adolescents averaged 14.9 years of age. Comparisons were made using analysis of variance incorporating hierarchical linear methods in SAS PROC MIXED to control family-related correlations in the data. Parents and children reported more conflict in adoptive families when compared with nonadoptive families. Families with 1 adopted and 1 nonadopted adolescent reported more conflict between parents and adopted adolescents. Observed parental behavior was similar across adoptive and nonadoptive children although adopted adolescents were less warm and, in families with 2 adopted children, more conflictual than nonadopted adolescents. These findings suggest a need for further investigation of the association between family interactions and adopted adolescent problem behavior. Copyright 2009 APA, all rights reserved.

  18. The involvement of family in child protection cases in Iceland

    Anni Haugen


    Full Text Available The aim of this study is to examine the involvement of families in child protection cases in Iceland, as well as to shed light on the attitudes of child protection workers on the importance of including families while working on child protection cases. The study is part of an international comparative analysis called: Social Work with Families: Social Workers’ Constructions of Family in Professional Practice. This article only addresses the Icelandic segment of the research. In the study, qualitative methods were used and three focus groups were conducted, in which the same three-step vignette about a child protection case was presented. The findings highlighted how difficult child protection workers found it to define the family. The main element is that family are those individuals closest to the child and connected to them through emotional ties, as Icelandic child protection workers seem to strive to involve family in child protection cases. However, there are signs which show that when working with more complicated cases the definition of a family becomes narrower, and involvement is restricted mostly to parents and grandparents. The findings also show that attitudes toward fathers differ from those toward mothers. The mother is expected to support and create security for the child, while the father is judged mostly on his violent behaviour and is not automatically regarded as providing support or actively taking responsibility for his child.

  19. Family caring strategies in neutropenia.

    Eggenberger, Sandra K; Krumwiede, Norma; Meiers, Sonja J; Bliesmer, Mary; Earle, Patricia


    Aggressive chemotherapy protocols result in neutropenia in approximately half of all patients receiving chemotherapy. Thus, neutropenia continues to be a significant and potentially life-threatening side effect of treatment, even with use of colony-stimulating factors. Families of patients with neutropenia often provide the primary healing environment because most chemotherapy protocols are managed on an outpatient basis. To learn about the family's experience of managing chemotherapy-induced neutropenia (CIN), a grounded-theory methodology was used to analyze data from seven families. The central theme revealed by these families was "turbulent waiting with intensified connections." This meant that when families had a sense of greater vulnerability in response to the waiting after diagnosis of CIN, they connected intensely with each other and healthcare providers. Families reported that connections with nurses became more significant when neutropenia interrupted chemotherapy. Families also developed family caring strategies to manage this period of waiting for the chemotherapy to resume. These strategies included family inquiry, family vigilance, and family balancing. Nurses need to be aware of approaches to support the family's ability to manage CIN. Interventions and approaches constructed from the perspective of a family-professional partnership will enhance the family cancer experience as well as ongoing family growth and function.
