    As one member of ADAR family, ADAR1 (adenosine deaminase acting on RNA 1) can convert adenosine to inosine within dsRNA. There are many ADAR1 splicing isoforms in mammals, including an interferon (IFN) inducible ∼150 kD protein (ADAR1-p150) and a constitutively expressed ∼110 kD protein (ADAR1-p110). The structural diversity of ADAR1 splicing isoforms may reflect their multiple functions. ADAR1 splicing isoforms were also found in fish. In our previous study, we have cloned and identified two different grass carp ADAR1 splicing isoforms, i.e. CiADAR1 and CiADAR1-like, both of them are IFN-inducible proteins. In this paper, we identified a novel CiADAR1 splicing isoform gene (named CiADAR1a). CiADAR1a gene contains 15 exons and 14 introns. Its full-length cDNA is comprised of a 5' UTR (359 bp), a 3' UTR (229 bp) and a 2952 bp ORF encoding a polypeptide of 983 amino acids with one Z-DNA binding domain, three dsRNA binding motifs and a highly conserved hydrolytic deamination domain. CiADAR1a was constitutively expressed in Ctenopharyngodon idella kidney (CIK) cells regardless of Poly I:C stimulation by Western blot assay. In normal condition, CiADAR1a was found to be present mainly in the nucleus. After treatment with Poly I:C, it gradually shifted to cytoplasm. To further investigate the mechanism of transcriptional regulation of CiADAR1a, we cloned and identified its promoter sequence. The transcriptional start site of CiADAR1a is mapped within the truncated exon 2. CiADAR1a promoter is 1303 bp in length containing 4 IRF-Es. In the present study, we constructed pcDNA3.1 eukaryotic expression vectors with IRF1 and IRF3 and co-transfected them with pGL3-CiADAR1a promoter into CIK cells. The results showed that neither the over-expression of IRF1 or IRF3 nor Poly I:C stimulation significantly impacted CiADAR1a promoter activity in CIK cells. Together, according to the molecular and expression characteristics, subcellular localization and transcriptional

    RNA editing catalyzed by ADAR1 and ADAR2 involves the site-specific conversion of adenosine to inosine within imperfectly duplexed RNA. ADAR1- and ADAR2-mediated editing occurs within transcripts of glutamate receptors (GluR) in the brain and in hepatitis delta virus (HDV) RNA in the liver. Although the Q/R site within the GluR-B premessage is edited more efficiently by ADAR2 than it is by ADAR1, the converse is true for the +60 site within this same transcript. ADAR1 and ADAR2 are homologs having two common functional regions, an N-terminal double-stranded RNA-binding domain and a C-terminal deaminase domain. It is neither understood why only certain adenosines within a substrate molecule serve as targets for ADARs, nor is it known which domain of an ADAR confers its specificity for particular editing sites. To assess the importance of several aspects of RNA sequence and structure on editing, we evaluated 20 different mutated substrates, derived from four editing sites, for their ability to be edited by either ADAR1 or ADAR2. We found that when these derivatives contained an A:C mismatch at the editing site, editing by both ADARs was enhanced compared to when A:A or A:G mismatches or A:U base pairs occurred at the same site. Hence substrate recognition and/or catalysis by ADARs could involve the base that opposes the edited adenosine. In addition, by using protein chimeras in which the deaminase domains were exchanged between ADAR1 and ADAR2, we found that this domain played a dominant role in defining the substrate specificity of the resulting enzyme.

    Adenosine deaminases that act on dsRNA (ADARs) are enzymes that target double-stranded regions of RNA converting adenosines into inosines (A-to-I editing) thus contributing to genome complexity and fine regulation of gene expression. It has been described that a member of the ADAR family, ADAR1, can target viruses and affect their replication process. Here we report evidence showing that ADAR1 stimulates human immuno deficiency virus type 1 (HIV-1) replication by using both editing-dependent and editing-independent mechanisms. We show that over-expression of ADAR1 in HIV-1 producer cells increases viral protein accumulation in an editing-independent manner. Moreover, HIV-1 virions generated in the presence of over-expressed ADAR1 but not an editing-inactive ADAR1 mutant are released more efficiently and display enhanced infectivity, as demonstrated by challenge assays performed with T cell lines and primary CD4+ T lymphocytes. Finally, we report that ADAR1 associates with HIV-1 RNAs and edits adenosines in the 5′ untranslated region (UTR) and the Rev and Tat coding sequence. Overall these results suggest that HIV-1 has evolved mechanisms to take advantage of specific RNA editing activity of the host cell and disclose a stimulatory function of ADAR1 in the spread of HIV-1.

    Flies with mutations in the single Drosophila Adar gene encoding an RNA editing enzyme involved in editing 4% of all transcripts have severe locomotion defects and develop age-dependent neurodegeneration. Vertebrates have two ADAR-editing enzymes that are catalytically active; ADAR1 and ADAR2. We show that human ADAR2 rescues Drosophila Adar mutant phenotypes. Neither the short nuclear ADAR1p110 isoform nor the longer interferon-inducible cytoplasmic ADAR1p150 isoform rescue walking defects efficiently, nor do they correctly edit specific sites in Drosophila transcripts. Surprisingly, human ADAR1p110 does suppress age-dependent neurodegeneration in Drosophila Adar mutants whereas ADAR1p150 does not. The single Drosophila Adar gene was previously assumed to represent an evolutionary ancestor of the multiple vertebrate ADARs. The strong functional similarity of human ADAR2 and Drosophila Adar suggests rather that these are true orthologs. By a combination of direct cloning and searching new invertebrate genome sequences we show that distinct ADAR1 and ADAR2 genes were present very early in the Metazoan lineage, both occurring before the split between the Bilateria and Cnidarians. The ADAR1 gene has been lost several times, including during the evolution of insects and crustacea. These data complement our rescue results, supporting the idea that ADAR1 and ADAR2 have evolved highly conserved, distinct functions. PMID:21622951

    Adenosine deaminase acting on RNA 1 (ADAR1) is an essential protein for embryonic liver development. ADAR1 loss is embryonically lethal because of severe liver damage. Although ADAR1 is required in adult livers to prevent liver cell death, as demonstrated by liver-specific conditional knockout (Alb-ADAR1(KO)) mice, the mechanism remains elusive. We systematically analyzed Alb-ADAR1(KO) mice for liver damage. Differentiation genes and inflammatory pathways were examined in hepatic tissues from Alb-ADAR1(KO) and littermate controls. Inducible ADAR1 KO mice were used to validate regulatory effects of ADAR1 on inflammatory cytokines. We found that Alb-ADAR1(KO) mice showed dramatic growth retardation and high mortality because of severe structural and functional damage to the liver, which showed overwhelming inflammation, cell death, fibrosis, fatty change, and compensatory regeneration. Simultaneously, Alb-ADAR1(KO) showed altered expression of key differentiation genes and significantly higher levels of hepatic inflammatory cytokines, especially type I interferons, which was also verified by inducible ADAR1 knockdown in primary hepatocyte cultures. We conclude that ADAR1 is an essential molecule for maintaining adult liver homeostasis and, in turn, morphological and functional integrity. It inhibits the production of type I interferons and other inflammatory cytokines. Our findings may provide novel insight in the pathogenesis of liver diseases caused by excessive inflammatory responses, including autoimmune hepatitis.

    Post-transcriptional adenosine-to-inosine RNA editing mediated by adenosine deaminase acting on RNA1 (ADAR1) promotes cancer progression and therapeutic resistance. However, ADAR1 editase-dependent mechanisms governing leukemia stem cell (LSC) generation have not been elucidated. In blast crisis chronic myeloid leukemia (BC CML), we show that increased JAK2 signaling and BCR-ABL1 amplification activate ADAR1. In a humanized BC CML mouse model, combined JAK2 and BCR-ABL1 inhibition prevents LSC self-renewal commensurate with ADAR1 downregulation. Lentiviral ADAR1 wild-type, but not an editing-defective ADAR1(E912A) mutant, induces self-renewal gene expression and impairs biogenesis of stem cell regulatory let-7 microRNAs. Combined RNA sequencing, qRT-PCR, CLIP-ADAR1, and pri-let-7 mutagenesis data suggest that ADAR1 promotes LSC generation via let-7 pri-microRNA editing and LIN28B upregulation. A small-molecule tool compound antagonizes ADAR1's effect on LSC self-renewal in stromal co-cultures and restores let-7 biogenesis. Thus, ADAR1 activation represents a unique therapeutic vulnerability in LSCs with active JAK2 signaling. PMID:27292188

    While exploring the effects of aerosol IFN-γ treatment in HIV-1/tuberculosis co-infected patients, we observed A to G mutations in HIV-1 envelope sequences derived from bronchoalveolar lavage (BAL) of aerosol IFN-γ-treated patients and induction of adenosine deaminase acting on RNA 1 (ADAR1) in the BAL cells. IFN-γ induced ADAR1 expression in monocyte-derived macrophages (MDM) but not T cells. ADAR1 siRNA knockdown induced HIV-1 expression in BAL cells of four HIV-1 infected patients on antiretroviral therapy. Similar results were obtained in MDM that were HIV-1 infected in vitro. Over-expression of ADAR1 in transformed macrophages inhibited HIV-1 viral replication but not viral transcription measured by nuclear run-on, suggesting that ADAR1 acts post-transcriptionally. The A to G hyper-mutation pattern observed in ADAR1 over-expressing cells in vitro was similar to that found in the lungs of HIV-1 infected patients treated with aerosol IFN-γ suggesting the model accurately represented alveolar macrophages. Together, these results indicate that ADAR1 restricts HIV-1 replication post-transcriptionally in macrophages harboring HIV-1 provirus. ADAR1 may therefore contribute to viral latency in macrophages.

    Summary The ADAR RNA-editing enzymes deaminate adenosine bases to inosines in cellular RNAs. Aberrant interferon expression occurs in patients in whom ADAR1 mutations cause Aicardi-Goutières syndrome (AGS) or dystonia arising from striatal neurodegeneration. Adar1 mutant mouse embryos show aberrant interferon induction and die by embryonic day E12.5. We demonstrate that Adar1 embryonic lethality is rescued to live birth in Adar1; Mavs double mutants in which the antiviral interferon induction response to cytoplasmic double-stranded RNA (dsRNA) is prevented. Aberrant immune responses in Adar1 mutant mouse embryo fibroblasts are dramatically reduced by restoring the expression of editing-active cytoplasmic ADARs. We propose that inosine in cellular RNA inhibits antiviral inflammatory and interferon responses by altering RLR interactions. Transfecting dsRNA oligonucleotides containing inosine-uracil base pairs into Adar1 mutant mouse embryo fibroblasts reduces the aberrant innate immune response. ADAR1 mutations causing AGS affect the activity of the interferon-inducible cytoplasmic isoform more severely than the nuclear isoform. PMID:25456137

    Unlike resting CD4+ T cells, activated CD4+T cells are highly susceptible to infection of human immunodeficiency virus 1 (HIV-1). HIV-1 infects T cells and macrophages without activating the nucleic acid sensors and the anti-viral type I interferon response. Adenosine deaminase acting on RNA 1 (ADAR1) is an RNA editing enzyme that displays antiviral activity against several RNA viruses. Mutations in ADAR1 cause the autoimmune disorder Aicardi-Goutieères syndrome (AGS). This disease is characterized by an inappropriate activation of the interferon-stimulated gene response. Here we show that HIV-1 replication, in ADAR1-deficient CD4+T lymphocytes from AGS patients, is blocked at the level of protein translation. Furthermore, viral protein synthesis block is accompanied by an activation of interferon-stimulated genes. RNA silencing of ADAR1 in Jurkat cells also inhibited HIV-1 protein synthesis. Our data support that HIV-1 requires ADAR1 for efficient replication in human CD4+T cells. PMID:26629815

    The blossom of immunotherapy in melanoma highlights the need to delineate mechanisms of immune resistance. Recently, we have demonstrated that the RNA editing protein, adenosine deaminase acting on RNA-1 (ADAR1) is down-regulated during metastatic transition of melanoma, which enhances melanoma cell proliferation and tumorigenicity. Here we investigate the role of ADAR1 in melanoma immune resistance. Importantly, knockdown of ADAR1 in human melanoma cells induces resistance to tumor infiltrating lymphocytes in a cell contact-dependent mechanism. We show that ADAR1, in an editing-independent manner, regulates the biogenesis of miR-222 at the transcription level and thereby Intercellular Adhesion Molecule 1 (ICAM1) expression, which consequently affects melanoma immune resistance. ADAR1 thus has a novel, pivotal, role in cancer immune resistance. Corroborating with these results, the expression of miR-222 in melanoma tissue specimens was significantly higher in patients who had no clinical benefit from treatment with ipilimumab as compared to patients that responded clinically, suggesting that miR-222 could function as a biomarker for the prediction of response to ipilimumab. These results provide not only novel insights on melanoma immune resistance, but also pave the way to the development of innovative personalized tools to enable optimal drug selection and treatment.

    The introduction of new therapies against particular genetic mutations in non-small-cell lung cancer is a promising avenue for improving patient survival, but the target population is small. There is a need to discover new potential actionable genetic lesions, to which end, non-conventional cancer pathways, such as RNA editing, are worth exploring. Herein we show that the adenosine-to-inosine editing enzyme ADAR1 undergoes gene amplification in non-small cancer cell lines and primary tumors in association with higher levels of the corresponding mRNA and protein. From a growth and invasion standpoint, the depletion of ADAR1 expression in amplified cells reduces their tumorigenic potential in cell culture and mouse models, whereas its overexpression has the opposite effects. From a functional perspective, ADAR1 overexpression enhances the editing frequencies of target transcripts such as NEIL1 and miR-381. In the clinical setting, patients with early-stage lung cancer, but harboring ADAR1 gene amplification, have poor outcomes. Overall, our results indicate a role for ADAR1 as a lung cancer oncogene undergoing gene amplification-associated activation that affects downstream RNA editing patterns and patient prognosis.

    Adenosine deaminases acting on RNA (ADARs) catalyze the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) and thereby potentially alter the information content and structure of cellular RNAs. Notably, although the overwhelming majority of such editing events occur in transcripts derived from Alu repeat elements, the biological function of non-coding RNA editing remains uncertain. Here, we show that mutations in ADAR1 (also known as ADAR) cause the autoimmune disorder Aicardi-Goutières syndrome (AGS). As in Adar1-null mice, the human disease state is associated with upregulation of interferon-stimulated genes, indicating a possible role for ADAR1 as a suppressor of type I interferon signaling. Considering recent insights derived from the study of other AGS-related proteins, we speculate that ADAR1 may limit the cytoplasmic accumulation of the dsRNA generated from genomic repetitive elements.

    It has been reported that social isolation stress could be a key factor that leads to cognitive deficit for both humans and rodent models. However, detailed mechanisms are not yet clear. ADAR1 (Adenosine deaminase acting on RNA) is an enzyme involved in RNA editing that has a close relation to cognitive function. We have hypothesized that social isolation stress may impact the expression of ADAR1 in the brain of mice with cognitive deficit. To test our hypothesis, we evaluated the cognition ability of mice isolated for different durations (2, 4, and 8 weeks) using object recognition and object location tests; we also measured ADAR1 expression in hippocampus and cortex using immunohistochemistry and western blot. Our study showed that social isolation stress induced spatial and non-spatial cognition deficits of the tested mice. In addition, social isolation significantly increased both the immunoreactivity and protein expression of ADAR1 (p110) in the hippocampus and frontal cortex. Furthermore, re-socialization could not only recover the cognition deficits, but also bring ADAR1 (p110) immunoreactivity of hippocampus and frontal cortex, as well as ADAR1 (p110) protein expression of hippocampus back to the normal level for the isolated mice in adolescence. In conclusion, social isolation stress significantly increases ADAR1 (p110) expression in the hippocampus and frontal cortex of the mice with cognitive deficit. This finding may open a window to better understand the reasons (e.g., epigenetic change) that are responsible for social isolation-induced cognitive deficit and help the development of novel therapies for the resulted diseases.

    It has been reported that social isolation stress could be a key factor that leads to cognitive deficit for both humans and rodent models. However, detailed mechanisms are not yet clear. ADAR1 (Adenosine deaminase acting on RNA) is an enzyme involved in RNA editing that has a close relation to cognitive function. We have hypothesized that social isolation stress may impact the expression of ADAR1 in the brain of mice with cognitive deficit. To test our hypothesis, we evaluated the cognition ability of mice isolated for different durations (2, 4, and 8 weeks) using object recognition and object location tests; we also measured ADAR1 expression in hippocampus and cortex using immunohistochemistry and western blot. Our study showed that social isolation stress induced spatial and non-spatial cognition deficits of the tested mice. In addition, social isolation significantly increased both the immunoreactivity and protein expression of ADAR1 (p110) in the hippocampus and frontal cortex. Furthermore, re-socialization could not only recover the cognition deficits, but also bring ADAR1 (p110) immunoreactivity of hippocampus and frontal cortex, as well as ADAR1 (p110) protein expression of hippocampus back to the normal level for the isolated mice in adolescence. In conclusion, social isolation stress significantly increases ADAR1 (p110) expression in the hippocampus and frontal cortex of the mice with cognitive deficit. This finding may open a window to better understand the reasons (e.g., epigenetic change) that are responsible for social isolation-induced cognitive deficit and help the development of novel therapies for the resulted diseases.

    Zalpha is a peptide motif that binds to Z-DNA with high affinity. This motif binds to alternating dC-dG sequences stabilized in the Z-conformation by means of bromination or supercoiling, but not to B-DNA. Zalpha is part of the N-terminal region of double-stranded RNA adenosine deaminase (ADAR1), a candidate enzyme for nuclear pre-mRNA editing in mammals. Zalpha is conserved in ADAR1 from many species; in each case, there is a second similar motif, Zbeta, separated from Zalpha by a more divergent linker. To investigate the structure-function relationship of Zalpha, its domain structure was studied by limited proteolysis. Proteolytic profiles indicated that Zalpha is part of a domain, Zab, of 229 amino acids (residues 133-361 in human ADAR1). This domain contains both Zalpha and Zbeta as well as a tandem repeat of a 49-amino acid linker module. Prolonged proteolysis revealed a minimal core domain of 77 amino acids (positions 133-209), containing only Zalpha, which is sufficient to bind left-handed Z-DNA; however, the substrate binding is strikingly different from that of Zab. The second motif, Zbeta, retains its structural integrity only in the context of Zab and does not bind Z-DNA as a separate entity. These results suggest that Zalpha and Zbeta act as a single bipartite domain. In the presence of substrate DNA, Zab becomes more resistant to proteases, suggesting that it adopts a more rigid structure when bound to its substrate, possibly with conformational changes in parts of the protein.

    RNA editing changes the read-out of genetic information, increasing the number of different protein products that can be made from a single gene. One form involves the deamination of adenosine to form inosine, which is subsequently translated as guanosine. The reaction requires a double-stranded RNA (dsRNA) substrate and is catalyzed by the adenosine deaminase that act on dsRNA (ADAR) family of enzymes. These enzymes possess dsRNA-binding domains (DRBM) and a catalytic domain. ADAR1 so far has been found only in vertebrates and is characterized by two Z-DNA-binding motifs, the biological function of which remains unknown. Here the role of the various functional domains of ADAR1 in determining the editing efficiency and specificity of ADAR1 is examined in cell-based assays. A variety of dsRNA substrates was tested. It was found that a 15-bp dsRNA stem with a single base mismatch was sufficient for editing. The particular adenosine modified could be varied by changing the position of the mismatch. Editing efficiency could be increased by placing multiple pyrimidines 5′ to the edited adenosine. With longer substrates, editing efficiency also increased and was partly due to the use of DRBMs. Additional editing sites were also observed that clustered on the complementary strand 11–15 bp from the first. An unexpected finding was that the DRBMs are not necessary for the editing of the shorter 15-bp substrates. However, mutation of the Z-DNA-binding domains of ADAR1 decreased the efficiency with which such a substrate was edited. PMID:11593027

    Internal ribosomal entry site (IRES)-mediated translation initiation is constitutively activated during stress conditions such as tumorigenesis and hypoxia. The RNA editing enzyme ADAR1 plays an important role in physiology and pathology. Initially, we found that the ADAR1 p150 or p110 transcript levels were decreased in glioma cells compared with normal astrocyte cells. In contrast, protein levels of ADAR1 p110 were significantly upregulated in glioma tissues and cells. This expression pattern indicated translationally controlled regulation. We identified an 885-nt sequence that was located between AUG1 and AUG2 within the ADAR1 mRNA that exhibited IRES-like activity. Furthermore, we confirmed that the translational mode of ADAR1 p110 was mediated by PTBP1 in glioma cells. The protein levels of PTBP1 and ADAR1 were cooperatively expressed in glioma tissues and cells. Knocking down ADAR1 p110 significantly decreased cell proliferation in three types of glioma cells (T98G, U87MG and A172). The removal of a minimal IRES-like sequence in a p150-overexpression construct could effectively abolish p110 induction and resulted in the slight suppression of cell proliferation compared with ADAR1-p150 overexpression in siPTBP1-treated T98G cells. In summary, our study revealed a mechanism whereby ADAR1 p110 can be activated by PTBP1 through an IRES-like element in glioma cells, and ADAR1 is essential for the maintenance of gliomagenesis.

    Transcripts encoding ADAR1, a double-stranded, RNA-specific adenosine deaminase involved in the adenosine-to-inosine (A-to-I) editing of mammalian RNAs, can be alternatively spliced to produce an interferon-inducible protein isoform (p150) that is up-regulated in both cell culture and in vivo model systems in response to pathogen or interferon stimulation. In contrast to other tissues, p150 is expressed at extremely low levels in the brain and it is unclear what role, if any, this isoform may play in the innate immune response of the central nervous system (CNS) or whether the extent of editing for RNA substrates critical for CNS function is affected by its induction. To investigate the expression of ADAR1 isoforms in response to viral infection and subsequent alterations in A-to-I editing profiles for endogenous ADAR targets, we used a neuro-tropic strain of reovirus to infect neonatal mice and quantify A-to-I editing in discrete brain regions using a multiplexed, high-throughput sequencing strategy. While intracranial injection of reovirus resulted in a widespread increase in the expression of ADAR1 (p150) in multiple brain regions and peripheral organs, significant changes in site-specific A-to-I conversion were quite limited, suggesting that steady-state levels of p150 expression are not a primary determinant for modulating the extent of editing for numerous ADAR targets in vivo.

    Equine infectious anemia virus (EIAV) is a member of the genus Lentivirus of the family Retroviridae. Horses are the most susceptible equids to EIAV infection and are therefore the primary hosts of this virus. In contrast, infected donkeys do not develop clinically active equine infectious anemia (EIA). This phenomenon is similar to what has been observed with HIV-1, which fails to induce AIDS in non-human primates. Interestingly, Shen et al. developed a donkey-tropic pathogenic virus strain (EIAVDV117, DV117) by serially passaging a horse-tropic pathogenic strain, EIAVLN40 (LN40), in donkeys. LN40, which was generated by passaging a field isolate in horses, displayed enhanced virulence in horses but caused no clinical symptoms in donkeys. Infection with DV117 induced acute EIA in nearly 100 % of donkeys. Genomic analysis of DV117 revealed a significantly higher frequency of A-to-G substitutions when compared to LN40. Furthermore, detailed analysis of dinucleotide editing showed that A-to-G mutations had a preference for 5'TpA and 5'ApA. These results strongly implicated the activity of the adenosine deaminase, ADAR1, in this type of mutation. Further investigation demonstrated that overexpression of donkey ADAR1 increased A-to-G mutations within the genome of EIAV. Together with our previous finding that multiple mutations in multiple genes are generated in DV117 during its adaptation from horses to donkeys, the present study suggests that ADAR1-induced A-to-G mutations occur during virus adaption to related new hosts contributing to the alteration of EIAV host tropism.

    The p150 form of the RNA-specific adenosine deaminase ADAR1 is interferon-inducible and catalyzes A-to-I editing of viral and cellular RNAs. We have characterized mouse genomic clones containing the promoter regions required for Adar1 gene transcription and analyzed interferon induction of the p150 protein using mutant mouse cell lines. Transient transfection analyses using reporter constructs led to the identification of three promoters, one interferon-inducible (PA) and two constitutively active (PB and PC). The TATA-less PA promoter, characterized by the presence of a consensus ISRE element and a PKR kinase KCS-like element, directed interferon-inducible reporter expression in rodent and human cells. Interferon induction of p150 was impaired in mouse cells deficient in IFNAR receptor, JAK1 kinase or STAT2 but not STAT1. Whereas Adar1 gene organization involving multiple promoters and alternative exon 1 structures was highly preserved, sequences of the promoters and exon 1 structures were not well conserved between human and mouse.

    Members of the double-stranded RNA- (dsRNA) specific adenosine deaminase gene family convert adenosine residues into inosines in dsRNA and are involved in A-to-I RNA editing of transcripts of glutamate receptor (GluR) subunits and serotonin receptor subtype 2C (5-HT(2C)R). We have isolated hADAR3, the third member of this class of human enzyme and investigated its editing site selectivity using in vitro RNA editing assay systems. As originally reported for rat ADAR3 or RED2, purified ADAR3 proteins could not edit GluR-B RNA at the "Q/R" site, the "R/G" site, and the intronic "hot spot" site. In addition, ADAR3 did not edit any of five sites discovered recently within the intracellular loop II region of 5-HT(2C)R RNAs, confirming its total lack of editing activity for currently known substrate RNAs. Filter-binding analyses revealed that ADAR3 is capable of binding not only to dsRNA but also to single-stranded RNA (ssRNA). Deletion mutagenesis identified a region rich in arginine residues located in the N-terminus that is responsible for binding of ADAR3 to ssRNA. The presence of this ssRNA-binding domain as well as its expression in restricted brain regions and postmitotic neurons make ADAR3 distinct from the other two ADAR gene family members, editing competent ADAR1 and ADAR2. ADAR3 inhibited in vitro the activities of RNA editing enzymes of the ADAR gene family, raising the possibility of a regulatory role in RNA editing. PMID:10836796

    The adenosine deaminases acting on RNA (ADAR) enzymes catalyse conversion of adenosine to inosine in dsRNA. A positive effect of ADAR1 on human immunodeficiency virus type 1 (HIV-1) replication has recently been reported. Here, we show that another ADAR enzyme, ADAR2, positively affects the replication process of HIV-1. We found that, analogously to ADAR1, ADAR2 enhances the release of progeny virions by an editing-dependent mechanism. However, differently from the ADAR1 enzyme, ADAR2 does not increase the infectious potential of the virus. Importantly, downregulation of ADAR2 in Jurkat cells significantly impairs viral replication. Therefore, ADAR2 shares some but not all proviral functions of ADAR1. These results suggest a novel role of ADAR2 as a viral regulator. PMID:21289159

    Adenosine deaminases acting on RNA (ADARs) are best known for altering the coding sequences of mRNA through RNA editing, as in the GluR-B Q/R site. ADARs have also been shown to affect RNA interference (RNAi) and microRNA processing by deamination of specific adenosines to inosine. Here, we show that ADAR proteins can affect RNA processing independently of their enzymatic activity. We show that ADAR2 can modulate the processing of mir-376a2 independently of catalytic RNA editing activity. In addition, in a Drosophila assay for RNAi deaminase-inactive ADAR1 inhibits RNAi through the siRNA pathway. These results imply that ADAR1 and ADAR2 have biological functions as RNA-binding proteins that extend beyond editing per se and that even genomically encoded ADARs that are catalytically inactive may have such functions.

    Adenosine deaminases acting on RNA (ADARs) convert adenosine to inosine in double-stranded RNA. This A-to-I editing occurs not only in protein-coding regions of mRNAs, but also frequently in non-coding regions that contain inverted Alu repeats. Editing of coding sequences can result in the expression of functionally altered proteins that are not encoded in the genome, whereas the significance of Alu editing remains largely unknown. Certain microRNA (miRNA) precursors are also edited, leading to reduced expression or altered function of mature miRNAs. Conversely, recent studies indicate that ADAR1 forms a complex with Dicer to promote miRNA processing, revealing a new function of ADAR1 in the regulation of RNA interference. PMID:26648264

    Urodele amphibians possess an amazing regenerative capacity that requires the activation of cellular plasticity in differentiated cells and progenitor/stem cells. Many aspects of regeneration in Urodele amphibians recapitulate development, making it unlikely that gene regulatory pathways which are essential for development are mutually exclusive from those necessary for regeneration. One such post-transcriptional gene regulatory pathway, which has been previously shown to be essential for functional metazoan development, is RNA editing. RNA editing catalyses discrete nucleotide changes in RNA transcripts, creating a molecular diversity that could create an enticing connection to the activated cellular plasticity found in newts during regeneration. To assess whether RNA editing occurs during regeneration, we demonstrated that GABRA3 and ADAR2 mRNA transcripts are edited in uninjured and regenerating tissues. Full open-reading frame sequences for ADAR1 and ADAR2, two enzymes responsible for adenosine-to-inosine RNA editing, were cloned from newt brain cDNA and exhibited a strong resemblance to ADAR (adenosine deaminase, RNA-specific) enzymes discovered in mammals. We demonstrated that ADAR1 and ADAR2 mRNA expression levels are differentially expressed during different phases of regeneration in multiple tissues, whereas protein expression levels remain unaltered. In addition, we have characterized a fascinating nucleocytoplasmic shuttling of ADAR1 in a variety of different cell types during regeneration, which could provide a mechanism for controlling RNA editing, without altering translational output of the editing enzyme. The link between RNA editing and regeneration provides further insights into how lower organisms, such as the newt, can activate essential molecular pathways via the discrete alteration of RNA sequences.

    Adenosine deaminases that act on RNA (ADARs) deaminate adenosines to inosines in double-stranded RNAs including miRNA precursors. A to I editing is widespread and required for normal life. By comparing deep sequencing data of brain miRNAs from wild-type and ADAR2 deficient mouse strains, we detect editing sites and altered miRNA processing at high sensitivity. We detect 48 novel editing events in miRNAs. Some editing events reach frequencies of up to 80%. About half of all editing events depend on ADAR2 while some miRNAs are preferentially edited by ADAR1. Sixty-four percent of all editing events are located within the seed region of mature miRNAs. For the highly edited miR-3099, we experimentally prove retargeting of the edited miRNA to novel 3′ UTRs. We show further that an abundant editing event in miR-497 promotes processing by Drosha of the corresponding pri-miRNA. We also detect reproducible changes in the abundance of specific miRNAs in ADAR2-deficient mice that occur independent of adjacent A to I editing events. This indicates that ADAR2 binding but not editing of miRNA precursors may influence their processing. Correlating with changes in miRNA abundance we find misregulation of putative targets of these miRNAs in the presence or absence of ADAR2. PMID:25260591

    To date, two structurally related RNA-editing enzymes with adenosine deaminase activity have been identified in mammalian tissue: ADAR1 and ADAR2 [Bass B. I. et al. (1997) RNA 3, 947-949]. In rodents, ADAR2 undergoes alternative RNA splicing, giving rise to two splice variants that differ by the presence or absence of a 10-amino-acid insert in the carboxy-terminal catalytic domain. However, the physiological significance of the splicing and its regional and developmental regulation are as yet unknown. The present study examined spatial and temporal patterns of ADAR2 gene transcripts within specific neuronal populations of rat brain. The two rodent ADAR2 isoforms were expressed at comparable levels at all ages examined. rADAR2 messenger RNA expression was first detectable in the thalamic nuclei formation at embryonic day E19. The rADAR2b insert and rADAR2a splice probes produced images similar to that of the rADAR2 pan probe. At birth, rADAR2a messenger RNA splice variants were abundantly expressed in the thalamic nuclei. No signal for any probe was detectable in other brain regions, including neocortex, hippocampus, striatum and cerebellum at this stage of development. During the first week of postnatal life, rADAR2 messenger RNA expression (detected with the pan probe) increased gradually in several brain regions, with low expression detected at postnatal day P7 in the olfactory bulb, inferior colliculus, and within the pyramidal and granule cell layers of the hippocampus. Hybridization patterns of the rADAR2a variant probe reached peak expression at about the second week of life, while peak expression of the rADAR2b probe was reached at about the third week of life. At the end of the first week of life (P7), expression of both splice variants was strongest in the thalamic nuclei. By P14, rADAR2 messenger RNA expression was more consolidated in the deeper structures, including the thalamic nuclei and the granule cell layer of the cerebellum. By P21, maximal levels

    A-to-I RNA editing operated by ADAR enzymes is extremely common in mammals. Several editing events in coding regions have pivotal physiological roles and affect protein sequence (recoding events) or function. We analyzed the evolutionary history of the 3 ADAR family genes and of their coding targets. Evolutionary analysis indicated that ADAR evolved adaptively in primates, with the strongest selection in the unique N-terminal domain of the interferon-inducible isoform. Positively selected residues in the human lineage were also detected in the ADAR deaminase domain and in the RNA binding domains of ADARB1 and ADARB2. During the recent history of human populations distinct variants in the 3 genes increased in frequency as a result of local selective pressures. Most selected variants are located within regulatory regions and some are in linkage disequilibrium with eQTLs in monocytes. Finally, analysis of conservation scores of coding editing sites indicated that editing events are counter-selected within regions that are poorly tolerant to change. Nevertheless, a minority of recoding events occurs at highly conserved positions and possibly represents the functional fraction. These events are enriched in pathways related to HIV-1 infection and to epidermis/hair development. Thus, both ADAR genes and their targets evolved under variable selective regimes, including purifying and positive selection. Pressures related to immune response likely represented major drivers of evolution for ADAR genes. As for their coding targets, we suggest that most editing events are slightly deleterious, although a minority may be beneficial and contribute to antiviral response and skin homeostasis.

    The ADAR proteins deaminate adenosine to inosine in double-stranded RNA which is one of the most abundant modifications present in mammalian RNA. Inosine can have a profound effect on the RNAs that are edited, not only changing the base-pairing properties, but can also result in recoding, as inosine behaves as if it were guanosine. In mammals there are three ADAR proteins and two ADAR-related proteins (ADAD) expressed. All have a very similar modular structure; however, both their expression and biological function differ significantly. Only two of the ADAR proteins have enzymatic activity. However, both ADAR and ADAD proteins possess the ability to bind double-strand RNA. Mutations in ADARs have been associated with many diseases ranging from cancer, innate immunity to neurological disorders. Here, we will discuss in detail the domain structure of mammalian ADARs, the effects of RNA editing, and the role of ADARs in human diseases. PMID:26437436

    The ADAR proteins deaminate adenosine to inosine in double-stranded RNA which is one of the most abundant modifications present in mammalian RNA. Inosine can have a profound effect on the RNAs that are edited, not only changing the base-pairing properties, but can also result in recoding, as inosine behaves as if it were guanosine. In mammals there are three ADAR proteins and two ADAR-related proteins (ADAD) expressed. All have a very similar modular structure; however, both their expression and biological function differ significantly. Only two of the ADAR proteins have enzymatic activity. However, both ADAR and ADAD proteins possess the ability to bind double-strand RNA. Mutations in ADARs have been associated with many diseases ranging from cancer, innate immunity to neurological disorders. Here, we will discuss in detail the domain structure of mammalian ADARs, the effects of RNA editing, and the role of ADARs in human diseases. PMID:26437436

    Nuclear factors 90 and 45 (NF90 and NF45) form a protein complex involved in the post-transcriptional control of many genes in vertebrates. NF90 is a member of the dsRNA binding domain (dsRBD) family of proteins. RNA binding partners identified so far include elements in 3' untranslated regions of specific mRNAs and several non-coding RNAs. In NF90, a tandem pair of dsRBDs separated by a natively unstructured segment confers dsRNA binding activity. We determined a crystal structure of the tandem dsRBDs of NF90 in complex with a synthetic dsRNA. This complex shows surprising similarity to the tandem dsRBDs from an adenosine-to-inosine editing enzyme, ADAR2 in complex with a substrate RNA. Residues involved in unusual base-specific recognition in the minor groove of dsRNA are conserved between NF90 and ADAR2. These data suggest that, like ADAR2, underlying sequences in dsRNA may influence how NF90 recognizes its target RNAs.

    Cape Adare stretches some 40km beyond the Antarctic Continent across the Continental Shelf. It is flanked to the east by the northern Ross Sea and to the West by Robertson Bay. The following characteristics make it an ideal monitoring and observation point to understand the impact of warm ocean and climate propogating into Antarctica from the Southern Ocean: 1) Robertson Bay is some 500m deep and has the potential to record deep water inflow which is predicted as climate warms and is also indicated as the biggest risk for melting Antarctic ice shelves. 2) Cape Adare also lies between the Antarctic continental high pressure and the Southern Ocean low pressure 3) Ridley Beach at the tip of the Peninsula is home to Antarctica's largest Adelie Penguin Colony In November 2015 we will conduct a pilot survey of the marine and terrestrial ecology and physical setting, with a view to determining what opportunities exist for a long term monitoring system. Cape Adare and the Ridley Beach Penguin Colony also offers the advantage of being on the edge of the proposed Ross Sea marine protected area and may represent an opportunity to monitor the associated ecosystem.

    Fragile X syndrome (FXS) is the most frequent inherited form of mental retardation. The cause for this X-linked disorder is the silencing of the fragile X mental retardation 1 (fmr1) gene and the absence of the fragile X mental retardation protein (Fmrp). The RNA-binding protein Fmrp represses protein translation, particularly in synapses. In Drosophila, Fmrp interacts with the adenosine deaminase acting on RNA (Adar) enzymes. Adar enzymes convert adenosine to inosine (A-to-I) and modify the sequence of RNA transcripts. Utilizing the fmr1 zebrafish mutant (fmr1-/-), we studied Fmrp-dependent neuronal circuit formation, behavior, and Adar-mediated RNA editing. By combining behavior analyses and live imaging of single axons and synapses, we showed hyperlocomotor activity, as well as increased axonal branching and synaptic density, in fmr1-/- larvae. We identified thousands of clustered RNA editing sites in the zebrafish transcriptome and showed that Fmrp biochemically interacts with the Adar2a protein. The expression levels of the adar genes and Adar2 protein increased in fmr1-/- zebrafish. Microfluidic-based multiplex PCR coupled with deep sequencing showed a mild increase in A-to-I RNA editing levels in evolutionarily conserved neuronal and synaptic Adar-targets in fmr1-/- larvae. These findings suggest that loss of Fmrp results in increased Adar-mediated RNA editing activity on target-specific RNAs, which, in turn, might alter neuronal circuit formation and behavior in FXS.

    ADAR2, an RNA editing enzyme that converts specific adenosines to inosines in certain pre-mRNAs, often leading to amino acid substitutions in the encoded proteins, is mainly expressed in brain. Of all ADAR2-mediated edits, a single one in the pre-mRNA of the AMPA receptor subunit GluA2 is essential for survival. Hence, early postnatal death of mice lacking ADAR2 is averted when the critical edit is engineered into both GluA2 encoding Gria2 alleles. Adar2−/−/Gria2R/R mice display normal appearance and life span, but the general phenotypic effects of global lack of ADAR2 have remained unexplored. Here we have employed the Adar2−/−/Gria2R/R mouse line, and Gria2R/R mice as controls, to study the phenotypic consequences of loss of all ADAR2-mediated edits except the critical one in GluA2. Our extended phenotypic analysis covering ∼320 parameters identified significant changes related to absence of ADAR2 in behavior, hearing ability, allergy parameters and transcript profiles of brain.

    An aeromagnetic survey was flown over the offshore region northeast of Cape Adare and the magnetic anomalies compared to onshore structures between Pennell Coast and Tucker Glacier. The magnetic anomalies show two nearly orthogonal major trends. NNW-SSE trending anomalies northeast of Cape Adare represent seafloor spreading within the Adare Trough. A connection of these anomalies to the Northern Basin of the Ross Sea is not clear. Onshore faults are closely aligned to offshore anomalies. Main trends are NW-SE to NNW-SSE and NE-SW to NNESSW. NNW-SSE oriented dextral-transtensional to extensional faults parallel the Adare Peninsula and Adare Trough anomalies. NE-SW trending normal faults appear to segment the main Hallett volcanic bodies.

    A reduction in adenosine deaminase acting on RNA 2 (ADAR2) activity causes the death of spinal motor neurons specifically via the GluA2 Q/R site-RNA editing failure in sporadic amyotrophic lateral sclerosis (ALS). We studied, over time, the spinal cords of ADAR2-knockout mice, which are the mechanistic model mice for sporadic ALS, using homozygous ADAR2(flox/flox)/VAChT-Cre.Fast (AR2), homozygous ADAR2(flox/flox)/VAChT-Cre.Slow (AR2Slow), and heterozygous ADAR2(flox/+)/VAChT-Cre.Fast (AR2H) mice. The conditional ADAR2-knockout mice were divided into 3 groups by stage: presymptomatic (AR2H mice), early symptomatic (AR2 mice, AR2H mice) and late symptomatic (AR2Slow mice). Light-microscopically, some motor neurons in AR2 and AR2H mice (presymptomatic) showed simple neuronal atrophy and astrogliosis, and AR2H (early symptomatic) and AR2Slow mice often showed vacuoles predominantly in motor neurons. The number of vacuole-bearing anterior horn neurons decreased with the loss of anterior horn neurons in AR2H mice after 40 weeks of age. Electron-microscopically, in AR2 mice, while the cytoplasm of normal-looking motor neurons was almost always normal-appearing, the interior of dendrites was frequently loose and disorganized. In AR2H and AR2Slow mice, large vacuoles without a limiting membrane were observed in the anterior horns, preferentially in the nuclei of motor neurons, astrocytes and oligodendrocytes. Nuclear vacuoles were not observed in AR2res (ADAR2(flox/flox)/VAChT-Cre.Fast/GluR-B(R/R)) mice, in which motor neurons express edited GluA2 in the absence of ADAR2. These findings suggest that ADAR2-reduction is associated with progressive deterioration of nuclear architecture, resulting in vacuolated nuclei due to a Ca(2+)-permeable AMPA receptor-mediated mechanism.

  6. A role of ADAR2 and RNA editing of glutamate receptors in mood disorders and schizophrenia

    PubMed Central

    2014-01-01

    Background Pre-mRNAs of 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)-propanoic acid (AMPA)/kainate glutamate receptors undergo post-transcriptional modification known as RNA editing that is mediated by adenosine deaminase acting on RNA type 2 (ADAR2). This modification alters the amino acid sequence and function of the receptor. Glutamatergic signaling has been suggested to have a role in mood disorders and schizophrenia, but it is unknown whether altered RNA editing of AMPA/kainate receptors has pathophysiological significance in these mental disorders. In this study, we found that ADAR2 expression tended to be decreased in the postmortem brains of patients with schizophrenia and bipolar disorder. Results Decreased ADAR2 expression was significantly correlated with decreased editing of the R/G sites of AMPA receptors. In heterozygous Adar2 knockout mice (Adar2+/− mice), editing of the R/G sites of AMPA receptors was decreased. Adar2+/− mice showed a tendency of increased activity in the open-field test and a tendency of resistance to immobility in the forced swimming test. They also showed enhanced amphetamine-induced hyperactivity. There was no significant difference in amphetamine-induced hyperactivity between Adar2+/− and wild type mice after the treatment with an AMPA/kainate receptor antagonist, 2,3-dihydroxy-6-nitro-7-sulfamoyl-benzo[f]quinoxaline. Conclusions These findings collectively suggest that altered RNA editing efficiency of AMPA receptors due to down-regulation of ADAR2 has a possible role in the pathophysiology of mental disorders.

    Misediting of the serotonin (5HT) 2C receptor (5HT2CR) has been implicated in both depression and anxiety. The adenosine deaminases that act on double stranded RNAs (ADARs) are reported to modify the 5HT2CR by RNA editing. Transgenic mice misexpressing the RNA editing enzyme ADAR2 show an adult onset obese phenotype due to chronic hyperphagia, but little more than this is known about the behavior of these animals. The present experiments examined whether affect-associated behaviors are also altered in ADAR2 transgenic mice. Age- and weight-matched transgenic mice misexpressing ADAR2 were tested for signs of behavioral despair with the forced swim (FST) and tail suspension (TST) tests, and for anxiety by evaluating spontaneous exploration in a novel environment and by elevated plus maze performance. Plasma corticosterone was also determined by radioimmunoassay. Transgenic mice of both sexes displayed indications of increased behavioral despair on first exposures to the TST and the FST. Behavioral despair persisted in ADAR2 mice in that it was also observed in the FST in tests administered 24 hr and 1 week following the initial TST and FST. ADAR2 transgenic mice also displayed behaviors associated with anxiety as indicated by decreased entry into the open arms in an elevated plus maze test. Both sexes of ADAR2 transgenic mice displayed elevated plasma corticosterone. Taken together, the results suggest that ADAR2 transgenic mice represent a novel rodent model of endogenous behavioral despair and anxiety accompanied by elevated hypothalamo-pituitary adrenal axis activity.

    Many biochemical and biophysical analyses of enzymes require quantities of protein that are difficult to obtain from expression in an endogenous system. To further complicate matters, native adenosine deaminases that act on RNA (ADARs) are expressed at very low levels, and overexpression of active protein has been unsuccessful in common bacterial systems. Here we describe the plasmid construction, expression, and purification procedures for ADARs overexpressed in the yeast Saccharomyces cerevisiae. ADAR expression is controlled by the Gal promoter, which allows for rapid induction of transcription when the yeast are grown in media containing galactose. The ADAR is translated with an N-terminal histidine tag that is cleaved by the tobacco etch virus protease, generating one nonnative glycine residue at the N-terminus of the ADAR protein. ADARs expressed using this system can be purified to homogeneity, are highly active in deaminating RNA, and are produced in quantities (from 3 to 10mg of pure protein per liter of yeast culture) that are sufficient for most biophysical studies.

    The Modulation Transfer Function (MTF) of an imaging system is one parameter that can be used to describe the spatial resolution or the image quality of an imaging system. MTF is the system's frequency response to an input. The MTF at a specific frequency normally ranges from 0-1, where 0 indicates no frequency response and 1 indicates perfect frequency response. The MTF value at Nyquist frequency is calculated because the Nyquist frequency is the maximum sampling frequency of the system. MTF analysis was performed on data acquired with an ADAR 5500 flown by Positive Systems on September 13-14, 2000 over Brookings, SD. Four edges from ground targets were used as inputs to the system. The system's MTF was calculated using a Matlab-based algorithm, which applied edge detection, numerical differentiation, and Fourier transformation methods to the target images.

    It has been postulated that synaptic potentiation during waking is offset by a homoeostatic reduction in net synaptic strength during sleep. However, molecular mechanisms to support such a process are lacking. Here we demonstrate that deficiencies in the RNA-editing gene Adar increase sleep due to synaptic dysfunction in glutamatergic neurons in Drosophila. Specifically, the vesicular glutamate transporter is upregulated, leading to over-activation of NMDA receptors, and the reserve pool of glutamatergic synaptic vesicles is selectively expanded in Adar mutants. Collectively these changes lead to sustained neurotransmitter release under conditions that would otherwise result in synaptic depression. We propose that a shift in the balance from synaptic depression towards synaptic potentiation in sleep-promoting neurons underlies the increased sleep pressure of Adar-deficient animals. Our findings provide a plausible molecular mechanism linking sleep and synaptic plasticity. PMID:26813350

    Alternative mRNA splicing is a major mechanism for gene regulation and transcriptome diversity. Despite the extent of the phenomenon, the regulation and specificity of the splicing machinery are only partially understood. Adenosine-to-inosine (A-to-I) RNA editing of pre-mRNA by ADAR enzymes has been linked to splicing regulation in several cases. Here we used bioinformatics approaches, RNA-seq and exon-specific microarray of ADAR knockdown cells to globally examine how ADAR and its A-to-I RNA editing activity influence alternative mRNA splicing. Although A-to-I RNA editing only rarely targets canonical splicing acceptor, donor, and branch sites, it was found to affect splicing regulatory elements (SREs) within exons. Cassette exons were found to be significantly enriched with A-to-I RNA editing sites compared with constitutive exons. RNA-seq and exon-specific microarray revealed that ADAR knockdown in hepatocarcinoma and myelogenous leukemia cell lines leads to global changes in gene expression, with hundreds of genes changing their splicing patterns in both cell lines. This global change in splicing pattern cannot be explained by putative editing sites alone. Genes showing significant changes in their splicing pattern are frequently involved in RNA processing and splicing activity. Analysis of recently published RNA-seq data from glioblastoma cell lines showed similar results. Our global analysis reveals that ADAR plays a major role in splicing regulation. Although direct editing of the splicing motifs does occur, we suggest it is not likely to be the primary mechanism for ADAR-mediated regulation of alternative splicing. Rather, this regulation is achieved by modulating trans-acting factors involved in the splicing machinery. PMID:23474544

    Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional process that amplifies the repertoire of protein production. Recently, the induction of this process through up-regulation of the editing enzyme RNA-specific adenosine deaminase 1 (ADAR1) was documented during acute inflammation. Here we report that the inflammation-induced up-regulation of ADAR1 involves differential production and intracellular localization of several isoforms with distinct RNA-binding domains and localization signals. These include the full-length ADAR1 (p150) and two functionally active short isoforms (p80 and p110). ADAR1 p80 starts at a methionine 519 (M519) due to alternative splicing in exon 2, which deletes the putative nuclear localization signal, the Z-DNA binding domain, and the entire RNA binding domain I. ADAR1 p110 is the mouse homologue of the human ADAR1 110-kDa variant (M246), which retains the second half of the Z-DNA binding domain, all RNA binding domains, and the deaminase domain. Additional variations are found in the third RNA binding domain of ADAR1; they are differentially regulated during inflammation, generating isoforms with different levels of activities. Studies in several cell types transfected with ADAR1-EGFP chimeras demonstrated that the p150 and p80 variants are localized in the cytoplasm and nucleolus, respectively. In agreement with this observation, endogenous ADAR1 was identified in the cytoplasm and nucleolus of mouse splenocytes and HeLa cells. Since the ADAR1 variants are differentially regulated during acute inflammation, it suggests that the localization of these variants and of A-to-I RNA editing in the cytoplasm, nucleus, and nucleolus is intracellularly reorganized in response to inflammatory stimulation.

    ADARs are found in Metazoans but are not present in yeasts. We have found that the methanol-utilizing yeast Pichia pastoris can be used to efficiently express enzymatically active epitope-tagged ADARs. We describe plasmid construction and protein expression procedures for producing Drosophila ADAR in this system.ADAR expression in Pichia pastoris uses the methanol-inducible alcohol oxidase AOX1 promoter for induction. A Zeocin resistance gene on the plasmid is used to select high copy number tandem integrations of the plasmid constructs. Preparation of extracts by grinding cultures in liquid nitrogen and purification protocols using 6 x HIS and FLAG epitope tags are described. Procedures for preparing radiolabeled dsRNA and for assaying the non-specific RNA editing activity of ADARs are described.ADARs produced in Escherichia coli are not enzymatically active. We describe expression of the ADAR dsRNA binding domains in E. coli using current versions of the T7 promoter based Studier vectors as well as the purification of the domains.

    Activation of AMPA receptors (AMPARs) in the nucleus accumbens is necessary for the reinstatement of cocaine-seeking behavior, an animal model of drug craving and relapse. AMPARs are tetrameric protein complexes that consist of GluA1-4 subunits, of which GluA2 imparts calcium permeability. Adenosine deaminase acting on RNA 2 (ADAR2) is a nuclear enzyme that is essential for editing GluA2 pre-mRNA at Q/R site 607. Unedited GluA2(Q) subunits form calcium-permeable AMPARs (CP-AMPARs), whereas edited GluA2(R) subunits form calcium-impermeable channels (CI-AMPARs). Emerging evidence suggests that the reinstatement of cocaine seeking is associated with increased synaptic expression of CP-AMPARs in the nucleus accumbens. However, the role of GluA2 Q/R site editing and ADAR2 in cocaine seeking is unclear. In the present study, we investigated the effects of forced cocaine abstinence on GluA2 Q/R site editing and ADAR2 expression in the nucleus accumbens. Our results demonstrate that 7 days of cocaine abstinence is associated with decreased GluA2 Q/R site editing and reduced ADAR2 expression in the accumbens shell, but not core, of cocaine-experienced rats compared with yoked saline controls. To examine the functional significance of ADAR2 and GluA2 Q/R site editing in cocaine seeking, we used viral-mediated gene delivery to overexpress ADAR2b in the accumbens shell. Increased ADAR2b expression in the shell attenuated cocaine priming-induced reinstatement of drug seeking and was associated with increased GluA2 Q/R site editing and surface expression of GluA2-containing AMPARs. Taken together, these findings support the novel hypothesis that an increased contribution of accumbens shell CP-AMPARs containing unedited GluA2(Q) promotes cocaine seeking. Therefore, CP-AMPARs containing unedited GluA2(Q) represent a novel target for cocaine addiction pharmacotherapies.

    We report the crystal structure of the catalytic domain of human ADAR2, an RNA editing enzyme, at 1.7 angstrom resolution. The structure reveals a zinc ion in the active site and suggests how the substrate adenosine is recognized. Unexpectedly, inositol hexakisphosphate (IP6) is buried within the enzyme core, contributing to the protein fold. Although there are no reports that adenosine deaminases that act on RNA (ADARs) require a cofactor, we show that IP6 is required for activity. Amino acids that coordinate IP6 in the crystal structure are conserved in some adenosine deaminases that act on transfer RNA (tRNA) (ADATs), related enzymes that edit tRNA. Indeed, IP6 is also essential for in vivo and in vitro deamination of adenosine 37 of tRNAala by ADAT1.

    Late Cenozoic lavas and associated hyaloclastite breccias of the Adare volcanics (Hallett volcanic province) in Robertson Bay, North Victoria Land rest unconformably on Paleozoic greywackes. Abundant hyaloclastite breccias are confined to a paleovalley; their primary geological features, and the stable isotope ratios of secondary minerals, are consistent with eruption in a subaqueous environment with calcite formation probably involving seawater. In contrast, the lavas which stratigraphically overlie the hyaloclastites on Mayr Spur probably were erupted subaerially. K-Ar dating of eight samples from this basal sequence confirms the known older age limit (Late Miocene) of the Hallett volcanic province. Geochemical data reveal an ocean island basalt-like affinity, similar to other Cenozoic igneous rocks of the Hallett volcanic province. If a submarine eruptive paleoenvironment is accepted then there has been net tectonic or isostatic post-Late Miocene uplift of a few hundred metres in the Robertson Bay-Adare Peninsula area

    Yeasts and filamentous fungi do not have adenosine deaminase acting on RNA (ADAR) orthologs and are believed to lack A-to-I RNA editing, which is the most prevalent editing of mRNA in animals. However, during this study with the PUK1 (FGRRES_01058) pseudokinase gene important for sexual reproduction in Fusarium graminearum, we found that two tandem stop codons, UA1831GUA1834G, in its kinase domain were changed to UG1831GUG1834G by RNA editing in perithecia. To confirm A-to-I editing of PUK1 transcripts, strand-specific RNA-seq data were generated with RNA isolated from conidia, hyphae, and perithecia. PUK1 was almost specifically expressed in perithecia, and 90% of transcripts were edited to UG1831GUG1834G. Genome-wide analysis identified 26,056 perithecium-specific A-to-I editing sites. Unlike those in animals, 70.5% of A-to-I editing sites in F. graminearum occur in coding regions, and more than two-thirds of them result in amino acid changes, including editing of 69 PUK1-like pseudogenes with stop codons in ORFs. PUK1 orthologs and other pseudogenes also displayed stage-specific expression and editing in Neurospora crassa and F. verticillioides. Furthermore, F. graminearum differs from animals in the sequence preference and structure selectivity of A-to-I editing sites. Whereas A's embedded in RNA stems are targeted by ADARs, RNA editing in F. graminearum preferentially targets A's in hairpin loops, which is similar to the anticodon loop of tRNA targeted by adenosine deaminases acting on tRNA (ADATs). Overall, our results showed that A-to-I RNA editing occurs specifically during sexual reproduction and mainly in the coding regions in filamentous ascomycetes, involving adenosine deamination mechanisms distinct from metazoan ADARs.

    ADAR (adenosine deaminases acting on RNA)-mediated adenosine-to-inosine (A-to-I) editing to double-stranded RNA (dsRNA) is a critical arm of the antiviral response. The present study focused on the structural and functional characterizations of grass carp (Ctenopharyngodon idella) ADAR2 (CiADAR2) gene. The complete genomic sequence of CiADAR2 is 150,458 bp in length, containing 12 exons and 11 introns. The open reading frame (ORF) of 2100 bp encodes a polypeptide of 699 amino acids (aa) which contains three highly conservative domains - two N-terminal dsRNA binding domains (dsRBDs) and one C-terminal deaminase domain. The predicted crystal structure of CiADAR2 deaminase domain suggested a catalytic center form in the enzyme active site. CiADAR2 mRNA was ubiquitously expressed in the fifteen tested tissues, and was induced post GCRV challenge in spleen and head kidney and C. idella kidney (CIK) cells. The ex vivo expression of CiADAR2 protein was verified by the Flag (tag)-based western blot assay. Antiviral activity assay of CiADAR2 was manifested by the delayed appearance of cytopathic effect (CPE) and inhibition of GCRV yield at 48 h post infection. Furthermore, in CiADAR2 overexpression cells, mRNA expression levels of CiIFN1, CiTLR7 and CiTLR8 were facilitated at different time points after GCRV infection, comparing to those in control group. Taken together, it was indicated that ADAR2 was an antiviral cytokine against GCRV and anti-GCRV function mechanism might involve in the TLR7/8-regulated IFN-signaling. These findings suggested that CiADAR2 was a novel member engaging in antiviral innate immune defense in C. idella, which laid a foundation for the further mechanism research of ADAR2 in fishes.

  20. Evidence for auto-inhibition by the N terminus of hADAR2 and activation by dsRNA binding.

    Adenosine deaminases that act on RNA (ADARs) catalyze adenosine to inosine conversion in RNA that is largely double stranded. Human ADAR2 (hADAR2) contains two double-stranded RNA binding motifs (dsRBMs), separated by a 90-amino acid linker, and these are followed by the C-terminal catalytic domain. We assayed enzymatic activity of N-terminal deletion constructs of hADAR2 to determine the role of the dsRBMs and the intervening linker peptide. We found that a truncated protein consisting of one dsRBM and the deaminase domain was capable of deaminating a short 15-bp substrate. In contrast, full-length hADAR2 was inactive on this short substrate. In addition, we observed that the N terminus, which was deleted from the truncated protein, inhibits editing activity when added in trans. We propose that the N-terminal domain of hADAR2 contains sequences that cause auto-inhibition of the enzyme. Our results suggest activation requires binding to an RNA substrate long enough to accommodate interactions with both dsRBMs.

    TDP-43 pathology in spinal motor neurons is a neuropathological hallmark of sporadic amyotrophic lateral sclerosis (ALS) and has recently been shown to be closely associated with the downregulation of an RNA editing enzyme called adenosine deaminase acting on RNA 2 (ADAR2) in the motor neurons of sporadic ALS patients. Because TDP-43 pathology is found more frequently in the brains of elderly patients, we investigated the age-related changes in the TDP-43 localization and ADAR2 activity in mouse motor neurons. We found that ADAR2 was developmentally upregulated, and its mRNA expression level was progressively decreased in the spinal cords of aged mice. Motor neurons normally exhibit nuclear ADAR2 and TDP-43 immunoreactivity, whereas fast fatigable motor neurons in aged mice demonstrated a loss of ADAR2 and abnormal TDP-43 localization. Importantly, these motor neurons expressed significant amounts of the Q/R site-unedited AMPA receptor subunit 2 (GluA2) mRNA. Because expression of unedited GluA2 has been demonstrated as a lethality-causing molecular abnormality observed in the motor neurons, these results suggest that age-related decreases in ADAR2 activity play a mechanistic role in aging and serve as one of risk factors for ALS.

    Mutations in the fused in sarcoma (FUS) gene can cause amyotrophic lateral sclerosis (ALS), and FUS gene mutations have been reported in sporadic ALS patients with basophilic cytoplasmic inclusions. Deficiency of adenosine deaminase acting on RNA 2 (ADAR2), an enzyme that specifically catalyzes GluA2 Q/R site-editing, has been reported in considerable proportions of spinal motor neurons of the majority of sporadic ALS patients. We describe the relationship between GluA2 Q/R site-editing efficiency and FUS-positive inclusions in a patient with FUS(P525L). A 24-year-old woman with ALS presented with basophilic cytoplasmic inclusions, significantly reduced GluA2 Q/R site-editing efficiency in the spinal motor neurons, and markedly decreased ADAR2 mRNA levels. Neuropathologic examination showed that not all spinal motor neurons expressed ADAR2 and revealed FUS-positive cytoplasmic inclusions in motor neurons irrespective of ADAR2 immunoreactivity. There were no phosphorylated transactive response (TAR) DNA-binding protein 43 kDa (TDP-43)-positive inclusions, indicating that there was no tight correlation between ADAR2 deficiency and TDP-43 deposition. ADAR2 deficiency can occur in ALS patients with a FUS(P525L) mutation and is unrelated to the presence of FUS-positive inclusions. FUS-associated ALS may share neurodegenerative characteristics with classical sporadic ALS.

    Post-transcriptional events play an important role in human development. The question arises as to whether Adenosine to Inosine RNA editing, catalyzed by the ADAR (Adenosine Deaminase acting on RNA) enzymes, differs in human embryogenesis and in adulthood. We tested the editing of various target genes in coding (FLNA, BLCAP, CYFIP2) and non-coding sequences at their Alu elements (BRCA1, CARD11, RBBP9, MDM4, FNACC), as well as the transcriptional levels of the ADAR1 enzymes. This analysis was performed on five fetal and adult human tissues: brain, heart, liver, kidney, and spleen, as well as on human embryonic stem cells (hESCs), which represent the blastocyst stage in early human development. Our results show substantially greater editing activity for most adult tissue samples relative to fetal ones, in six of the eight genes tested. To test the effect of reduced A-to-I RNA editing activity in early human development we used human embryonic stem cells (hESCs) as a model and tried to generate hESC clones that overexpress the ADAR1–p110 isoform. We were unable to achieve overexpression of ADAR1–p110 by either transfection or lentiviral infection, though we easily generated hESC clones that expressed the GFP transgene and overexpressed ADAR1-p110 in 293T cells and in primary human foreskin fibroblast (HFF) cells. Moreover, in contrast to the expected overexpression of ADAR1-p110 protein following its introduction into hESCs, the expression levels of this protein decreased dramatically 24–48 hr post infection. Similar results were obtained when we tried to overexpress ADAR1-p110 in pluripotent embryonal carcinoma cells. This suggests that ADAR1 protein is substantially regulated in undifferentiated pluripotent hESCs. Overall, our data suggest that A-to-I RNA editing plays a critical role during early human development. PMID:22859999

    Aicardi–Goutières syndrome is an inflammatory disease occurring due to mutations in any of TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR or IFIH1. We report on 374 patients from 299 families with mutations in these seven genes. Most patients conformed to one of two fairly stereotyped clinical profiles; either exhibiting an in utero disease-onset (74 patients; 22.8% of all patients where data were available), or a post-natal presentation, usually within the first year of life (223 patients; 68.6%), characterized by a sub-acute encephalopathy and a loss of previously acquired skills. Other clinically distinct phenotypes were also observed; particularly, bilateral striatal necrosis (13 patients; 3.6%) and non-syndromic spastic paraparesis (12 patients; 3.4%). We recorded 69 deaths (19.3% of patients with follow-up data). Of 285 patients for whom data were available, 210 (73.7%) were profoundly disabled, with no useful motor, speech and intellectual function. Chilblains, glaucoma, hypothyroidism, cardiomyopathy, intracerebral vasculitis, peripheral neuropathy, bowel inflammation and systemic lupus erythematosus were seen frequently enough to be confirmed as real associations with the Aicardi-Goutieres syndrome phenotype. We observed a robust relationship between mutations in all seven genes with increased type I interferon activity in cerebrospinal fluid and serum, and the increased expression of interferon-stimulated gene transcripts in peripheral blood. We recorded a positive correlation between the level of cerebrospinal fluid interferon activity assayed within one year of disease presentation and the degree of subsequent disability. Interferon-stimulated gene transcripts remained high in most patients, indicating an ongoing disease process. On the basis of substantial morbidity and mortality, our data highlight the urgent need to define coherent treatment strategies for the phenotypes associated with mutations in the Aicardi–Goutières syndrome

    RNA editing by adenosine deaminases that act on RNA (ADARs) diversifies the transcriptome by changing adenosines to inosines. In mammals, editing levels vary in different tissues, during development, and also in pathogenic conditions. From a screen for repressors of editing we have isolated three proteins that repress ADAR2-mediated RNA editing. The three proteins RPS14, SFRS9 and DDX15 interact with RNA. Overexpression or depletion of these proteins can decrease or increase editing levels by 15%, thus allowing a modulation of RNA editing up to 30%. Interestingly, the three proteins alter RNA editing in a substrate-specific manner that correlates with their RNA binding preferences. In mammalian cells, SFRS9 significantly affects editing of the two substrates CFLAR and cyFIP2, while the ribosomal protein RPS14 mostly inhibits editing of cyFIP2 messenger RNA. The helicase DDX15, in turn, has a strong effect on editing in Caenorhabditis elegans. Expression of the three factors decreases during mouse brain development. Moreover, expression levels of SFRS9 and DDX15 respond strongly to neuronal stimulation or repression, showing an inverse correlation with editing levels. Colocalization and immunoprecipitation studies demonstrate a direct interaction of SFRS9 and RPS14 with ADAR2, while DDX15 associates with other helicases and splicing factors. Our data show that different editing sites can be specifically altered in their editing pattern by changing the local RNP landscape. PMID:23275536

    Adenosine to Inosine (A-to-I) RNA editing is a site-specific modification of RNA transcripts, catalyzed by members of the ADAR (Adenosine Deaminase Acting on RNA) protein family. RNA editing occurs in human RNA in thousands of different sites. Some of the sites are located in protein-coding regions but the majority is found in non-coding regions, such as 3′UTRs, 5′UTRs and introns - mainly in Alu elements. While editing is found in all tissues, the highest levels of editing are found in the brain. It was shown that editing levels within protein-coding regions are increased during embryogenesis and after birth and that RNA editing is crucial for organism viability as well as for normal development. In this study we characterized the A-to-I RNA editing phenomenon during neuronal and spontaneous differentiation of human embryonic stem cells (hESCs). We identified high editing levels of Alu repetitive elements in hESCs and demonstrated a global decrease in editing levels of non-coding Alu sites when hESCs are differentiating, particularly into the neural lineage. Using RNA interference, we showed that the elevated editing levels of Alu elements in undifferentiated hESCs are highly dependent on ADAR1. DNA microarray analysis showed that ADAR1 knockdown has a global effect on gene expression in hESCs and leads to a significant increase in RNA expression levels of genes involved in differentiation and development processes, including neurogenesis. Taken together, we speculate that A-to-I editing of Alu sequences plays a role in the regulation of hESC early differentiation decisions. PMID:20574523

    Chordoma is a rare, slow-growing primary malignant neoplasm of the axial skeleton, which arises from the remnants of the notochord. Emerging evidence suggests that microRNAs (miRs) are dysregulated in chordoma tissues and crucially involved in chordoma pathogenesis. In the present study, the expression of 11 candidate miRs were analyzed in chordoma tissues and miR-10a and miR-125a were found to be significantly downregulated compared with controls. Notably, the expression of the primary transcripts, pri-miR-125a and pri-miR-10a was unaltered, suggesting that disturbed microRNA expression may be induced by altered pri-miRNA processing. Previous studies have indicated that disturbed adenosine deaminase acting on RNA (ADAR) expression is able to alter mRNA and miRNA adenosine to inosine (A-to-I) levels associated with cancer pathogenesis. Therefore, the expression of ADAR1 and ADAR2 was analyzed in chordoma tissues. It was found that ADAR1 was significantly overexpressed, which was accompanied by enhanced pre-miR-10a and pri-miR-125a A-to-I editing. These findings suggest that ADAR2 overexpression causes enhanced pre-miR-10a and pri-miR-125a A-to-I editing, which alters mature miR-10a and miR-125a expression and may contribute to chordoma pathogenesis.

    Z-DNA is a high energy conformer of B-DNA that forms in vivo during transcription as a result of torsional strain generated by a moving polymerase. An understanding of the biological role of Z-DNA has advanced with the discovery that the RNA editing enzyme double-stranded RNA adenosine deaminase type I (ADAR1) has motifs specific for the Z-DNA conformation. Editing by ADAR1 requires a double-stranded RNA substrate. In the cases known, the substrate is formed by folding an intron back onto the exon that is targeted for modification. The use of introns to direct processing of exons requires that editing occurs before splicing. Recognition of Z-DNA by ADAR1 may allow editing of nascent transcripts to be initiated immediately after transcription, ensuring that editing and splicing are performed in the correct sequence. Structural characterization of the Z-DNA binding domain indicates that it belongs to the winged helix-turn-helix class of proteins and is similar to the globular domain of histone-H5.

    ABSTRACT Defective interfering RNAs (DI-RNAs) of the viral genome can form during infections of negative-strand RNA viruses and outgrow full-length viral genomes, thereby modulating the severity and duration of infection. Here we document the frequent de novo generation of copy-back DI-RNAs from independent rescue events both for a vaccine measles virus (vac2) and for a wild-type measles virus (IC323) as early as passage 1 after virus rescue. Moreover, vaccine and wild-type C-protein-deficient (C-protein-knockout [CKO]) measles viruses generated about 10 times more DI-RNAs than parental virus, suggesting that C enhances the processivity of the viral polymerase. We obtained the nucleotide sequences of 65 individual DI-RNAs, identified breakpoints and reinitiation sites, and predicted their structural features. Several DI-RNAs possessed clusters of A-to-G or U-to-C transitions. Sequences flanking these mutation sites were characteristic of those favored by adenosine deaminase acting on RNA-1 (ADAR1), which catalyzes in double-stranded RNA the C-6 deamination of adenosine to produce inosine, which is recognized as guanosine, a process known as A-to-I RNA editing. In individual DI-RNAs the transitions were of the same type and occurred on both sides of the breakpoint. These patterns of mutations suggest that ADAR1 edits unencapsidated DI-RNAs that form double-strand RNA structures. Encapsidated DI-RNAs were incorporated into virus particles, which reduced the infectivity of virus stocks. The CKO phenotype was dominant: DI-RNAs derived from vac2 with a CKO suppressed the replication of vac2, as shown by coinfections of interferon-incompetent lymphatic cells with viruses expressing different fluorescent reporter proteins. In contrast, coinfection with a C-protein-expressing virus did not counteract the suppressive phenotype of DI-RNAs. IMPORTANCE Recombinant measles viruses (MVs) are in clinical trials as cancer therapeutics and as vectored vaccines for HIV-AIDS and

    RNA editing by the host RNA adenosine deaminase ADAR1 at the amber/W site of hepatitis delta virus RNA plays a central role in the viral replication cycle by affecting the balance between viral RNA synthesis and packaging. Previously, we found that HDV genotype III (HDV-3) RNA can form two secondary structures following transcription: an unbranched rod structure, which is characteristic of HDV, and a metastable branched structure that serves as the substrate for editing. The unstable nature of the branched editing substrate structure raised the possibility that structural dynamics of the RNA following transcription could determine the rate at which editing occurs. Here, editing and its control are examined in two HDV-3 isolates, from Peru and Ecuador. Analysis of editing in vitro by ADAR1 indicated that the branched structure formed by RNA derived from the Peruvian isolate is edited more efficiently than that from the Ecuadorian isolate. In contrast, in the context of replication, Peruvian RNA is edited less efficiently than RNA containing Ecuadorian sequences. Computational analyses of RNA folding using the massively parallel genetic algorithm (MPGAfold) indicated that the Peruvian RNA is less likely to form the branched structure required for editing than the Ecuadorian isolate. This difference was confirmed by in vitro transcription of these RNAs. Overall, our data indicate that HDV-3 controls RNA editing levels via (1) the fraction of the RNA that folds, during transcription, into the metastable branched structure required for editing and (2) the efficiency with which ADAR1 edits this branched substrate RNA.

    RNA editing plays a critical role in the life cycle of hepatitis delta virus (HDV). The host editing enzyme ADAR1 recognizes specific RNA secondary structure features around the amber/W site in the HDV antigenome and deaminates the amber/W adenosine. A previous report suggested that a branched secondary structure is necessary for editing in HDV genotype III. This branched structure, which is distinct from the characteristic unbranched rod structure required for HDV replication, was only partially characterized, and knowledge concerning its formation and stability was limited. Here, we examine the secondary structures, conformational dynamics, and amber/W site editing of HDV genotype III RNA using a miniaturized HDV genotype III RNA in vitro. Computational analysis of this RNA using the MPGAfold algorithm indicated that the RNA has a tendency to form both metastable and stable unbranched secondary structures. Moreover, native polyacrylamide gel electrophoresis demonstrated that this RNA forms both branched and unbranched rod structures when transcribed in vitro. As predicted, the branched structure is a metastable structure that converts readily to the unbranched rod structure. Only branched RNA was edited at the amber/W site by ADAR1 in vitro. The structural heterogeneity of HDV genotype III RNA is significant because not only are both conformations of the RNA functionally important for viral replication, but the ratio of the two forms could modulate editing by determining the amount of substrate RNA available for modification.

    Aicardi-Goutières syndrome (AGS) is a monogenic inflammatory encephalopathy caused by mutations in TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR1, or MDA5. Mutations in those genes affect normal RNA/DNA intracellular metabolism and detection, triggering an autoimmune response with an increase in cerebral IFN-α production by astrocytes. Microangiopathy and vascular disease also contribute to the neuropathology in AGS. In this study, we report that AGS gene silencing of TREX1, SAMHD1, RNASEH2A, and ADAR1 by short hairpin RNAs in human neural stem cell-derived astrocytes, human primary astrocytes, and brain-derived endothelial cells leads to an antiviral status of these cells compared with nontarget short hairpin RNA-treated cells. We observed a distinct activation of the IFN-stimulated gene signature with a substantial increase in the release of proinflammatory cytokines (IL-6) and chemokines (CXCL10 and CCL5). A differential impact of AGS gene silencing was noted; silencing TREX1 gave rise to the most dramatic in both cell types. Our findings fit well with the observation that patients carrying mutations in TREX1 experience an earlier onset and fatal outcome. We provide in the present study, to our knowledge for the first time, insight into how astrocytic and endothelial activation of antiviral status may differentially lead to cerebral pathology, suggesting a rational link between proinflammatory mediators and disease severity in AGS.

    Ribonuclease H2 (RNase H2) belongs to the family of RNase H enzymes, which process RNA/DNA hybrids. Apart from cleaving the RNA moiety of a plain RNA/DNA hybrid, RNase H2 participates in the removal of single ribonucleotides embedded in a DNA duplex. Mutations in RNase H2 lead to the chronic inflammatory disorder Aicardi-Goutières syndrome (AGS), which has significant phenotypic overlaps with the autoimmune disease systemic lupus erythematosus. RNase H2 knock-out mice are embryonic lethal. Mouse embryos lacking RNase H2 accumulate DNA damage and exhibit a p53-mediated growth arrest commencing at gastrulation. On a molecular level, the knock-out mice reveal that RNase H2 represents an essential DNA repair enzyme, whose main cellular function is the removal of accidentally misincorporated ribonucleotides from genomic DNA. Ribonucleotides strongly accumulate within the genomic DNA of RNase H2-deficient cells, in turn resulting in a massive build-up of DNA damage in these cells. The DNA lesions that arise from misincorporated ribonucleotides constitute the by far most frequent type of naturally occurring DNA damage. AGS-causing mutations have also been found in the genes of the 3'-exonuclease TREX1, the dNTP triphosphatase SAMHD1, as well as the RNA-editing enzyme ADAR1, defining defects in nucleic acid metabolism pathways as a common hallmark of AGS pathology. However, recent evidence gathered from RNase H2 knock-out mice might provide additional insight into the molecular mechanisms underlying AGS development and a potential role of DNA damage as a trigger of autoimmunity is discussed.

    2015-02-01

    Familial leukemia has been described for more than 50 years but only recently have modern genetic techniques allowed for the investigation of the genome. Genome-wide association studies have identified a number of genetic sites that appear to relate to susceptibility to leukemia in certain families and occasionally to susceptibility to a specific leukemia in general. Many questions remain, including susceptibility to what? An oncogenic virus? An environmental chemical? Mutation of another gene induced by a heritable mutation-promoting gene?.Clinically important facts have been learned. Chronic lymphocytic leukemia (CLL) is by far the most common familial leukemia. Patients with CLL have approximately a 10% chance of a first-degree relative developing CLL, and even a greater chance of one developing monoclonal B-cell lymphocytosis which may be an asymptomatic forme fruste of the neoplasm. Furthermore, there may be an increased incidence of breast cancer in familial CLL pedigrees which raises the question of a common etiology for neoplasms in general, or at least a previously unrecognized relationship among them.

  16. FAMILY BOMBYLIIDAE.

    PubMed

    Lamas, Carlos José Einicker; Evenhuis, Neal L

    2016-01-01

    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. PMID:27395279

    Familial hypercholesterolemia is a common, inherited disorder of cholesterol metabolism that leads to early cardiovascular morbidity and mortality. It is underdiagnosed and undertreated. Statins, ezetimibe, bile acid sequestrants, niacin, lomitapide, mipomersen and LDL apheresis are treatments that can lower LDL cholesterol levels. Early treatment can lead to substantial reduction of cardiovascular events and death in patients with FH. It is important to increase awareness of this disorder in physicians and patients in order to reduce the burden of this disorder. PMID:25939291

  18. Familial hypercholesterolemia

    PubMed Central

    Turgeon, Ricky D.; Barry, Arden R.; Pearson, Glen J.

    2016-01-01

    Objective To summarize the pathophysiology, epidemiology, screening, diagnosis, and treatment of familial hypercholesterolemia (FH). Quality of evidence A PubMed search was conducted (inception to July 2014) for articles on pathophysiology, screening, diagnosis, and management of FH, supplemented with hand searches of bibliographies of guidelines and reviews. A supporting level of evidence for each recommendation was categorized as level I (randomized controlled trial or systematic review of randomized controlled trials), level II (observational study), or level III (expert opinion). The best available evidence is mostly level II or III. Main message Familial hypercholesterolemia affects 1 in 500 Canadians. Risk of a coronary event is high in these patients and is underestimated by risk calculators (eg, Framingham). Clinicians should screen patients according to guidelines and suspect FH in any patient with a premature cardiovascular event, physical stigmata of hypercholesterolemia, or an elevated plasma lipid level. Physicians should diagnose FH using either the Simon Broome or Dutch Lipid Network criteria. Management of heterozygous FH includes reducing low-density lipoprotein levels by 50% or more from baseline with high-dose statins and other lipid-lowering agents. Clinicians should refer any patient with homozygous FH to a specialized centre. Conclusion Familial hypercholesterolemia represents an important cause of premature cardiovascular disease in Canadians. Early identification and aggressive treatment of individuals with FH reduces cardiovascular morbidity and mortality. PMID:26796832

  20. Family and family therapy in the Netherlands.

    PubMed

    Wagenaar, Karin; Baars, Jan

    2012-04-01

    This article describes how families are functioning in the Netherlands, and how family therapy is used in mental healthcare. In the open Dutch society, new ideas are easily incorporated, as exemplified by the rapid introduction and growth of family therapy in the 1980s. In recent decades, however, family therapy has lost ground to other treatment models that are more individually orientated, and adhere to stricter protocols. This decline of family therapy has been exacerbated by recent budget cuts in mental healthcare. In regular healthcare institutes family therapy now has a marginal position at best, although family treatment models are used in specific areas such as forensic treatments. In addition, the higher trained family therapists have found their own niches to work with couples and families. We argue that a stronger position of family therapy would be beneficial for patients and for families, in order to counteract the strong individualization of Dutch society. PMID:22515464

    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.

  5. Familial Ebstein's anomaly.

    1976-01-01

    A family is described in which both a father and son are affected with Ebstein's anomaly, while several other family members manifest different cardiac malformations. Five additional instances of familial Ebstein's anomaly were found in the literature and compared with our family. Inspection of possible modes of inheritance in this group of families suggests that Ebstein's anomaly is probably inherited as a polygenic character with a threshold phenomenon. PMID:1018315

    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.

    PubMed

    Breunlin, Douglas C; Jacobsen, Elizabeth

    2014-09-01

    In this article, we examine the field of family therapy by drawing a distinction between two forms of practice: Whole Family Therapy (WFT), defined as treating the whole family, and Relational Family Therapy (RFT), defined as working with a subsystem of the family or an individual while retaining a systemic lens. Our thesis is that the practice of WFT has been in decline for some time and steps must be taken to keep it from becoming a defunct practice. We consider the trajectory of WFT and RFT throughout the development of family therapy through reference to the people, the literature, training, and practice patterns associated with family therapy. We remind the reader of the many benefits of WFT and suggest that today WFT is likely to be practiced in conjunction with RFT and individual therapy. Since training of family therapists today is largely located in degree-granting programs, we identify constraints to including WFT in such programs. We conclude by offering suggestions that can enhance a program's ability to train students in WFT.

    The family is an integral part of one's life. It is very essential that every individual employed or unemployed invests time therein. The family is a source of support and growth for an individual, and the lack of family support or loneliness may be a causative factor in the genesis of psychiatric disorders, especially depression. In India, family plays a paramount role when it comes to mental health of the individual. Tips on how one should invest time in one's family along with the role of a family in one's personal and social structure are discussed. PMID:25838732

  12. Familial myeloproliferative disease.

    PubMed

    Gilbert, H S

    1998-12-01

    The occurrence of one or more myeloproliferative disease (MPD) syndromes in 42 families is described. MPD appeared in a single generation in 10 families, two generations in 30 families and three generations in two families. In contrast to sparse case reports of familial polycythaemia vera, familial essential thrombocythaemia, or familial agnogenic myeloid metaplasia, in which all the involved members presented with the same MPD, 21 of the 42 families in the present series had members who presented with different MPD variants. The occurrence of multiple disease phenotypes in 'MPD families' is entirely consistent with the accepted theory of MPD as a disease arising from clonal expansion of a pluripotential haematopoietic precursor cell (PHPC) that retains its pluripotentiality and produces an array of inter-related syndromes, each named for the predominant haematic cell type involved in the proliferation. Changes in disease phenotype during the course of MPD and 'hybrid' phenotypes at the time of diagnosis are common. This report challenges the previously accepted belief that PV and other MPD variants are sporadic and randomly-occurring, and that familial occurrence of MPD is rare. The ability to identify 'MPD families' by surveying a large population of patients with MPD through the Internet, as was done in this study, and heightened awareness of familial occurrence and its phenotypic heterogeneity, should facilitate further characterization of the mode of inheritance in familial MPD and the nature of the gene mutations responsible for the dysregulation of haematopoiesis.

    2006-01-01

    Because children of mentally disordered parents have an increased risk of becoming subjects of mental disorder and psychological problems, adult psychiatry has increasingly paid attention to the patients' parental skills. This study includes 31 families with children younger than 18 years of age where the parents were admitted to family therapy in an open psychiatric ward. The average number of sessions was seven, and the diagnoses of severe stress and of adjustment disorder were the most common. The aim of the study was to measure changes in the family climate during the period of therapy. The instrument used was the Family Environment Scale (FES), a self-rating questionnaire that measures the parents' experience of family environment. The change of family environment is related to its influence on children's well-being and development. The study finds that family therapy has resulted in positive changes of the parents' experience of the family climate.

    1993-01-01

    Family planning programs since their beginnings have focused exclusively on women. The importance of male participation in family planning has not been recognized. Today's society demands greater understanding and empathy between spouses, if they are to meet the new and difficult challenges of modern life. Incorporation of men into family planning programs is needed because of the deteriorating live conditions of a large segment of the population and the accelerating decomposition of social structures. Persuading men to participate in family planning should strengthen the couple and increase the probability that decisions about family size will be responsible. Strategies should be designed to interest men in family planning and increase their awareness of their role in fathering happy children who enter the world in more just and humane conditions. Such strategies must combat sex role socialization that begins in infancy. The assignment of responsibility for family planning to the woman excludes men from what should be a fundamental role.

    Familial pituitary tumors are relatively rare. Most commonly, they occur as a part of multiple endocrine neoplasia type 1 (MEN 1). However, familial pituitary adenomas unrelated MEN 1 (familial pituitary adenomas) are extremely rare. In review of MEN 1 in Japan, 60% of the patients with MEN 1 had pituitary tumors. Only 45 cases of familial pituitary adenomas have been reported from 20 families. In our review of familial pituitary adenomas, 30 (67%) of 45 reported cases are acromegaly or gigantism. This incidence is much higher than 28% in MEN 1 patients with pituitary tumors. Allelic deletions at 11q13 were identified in MEN 1 associated pituitary adenomas and familial pituitary adenomas in two gigantism brothers. PMID:8538028

  7. Rethinking family power.

    PubMed

    Kranichfeld, M L

    1987-03-01

    The family power literature, in its macrolevel focus on marital decision-making, has emphasized the kind of family power that is generally conferred on men and is based on extrafamilial roles and performances. Kranichfeld argues that for the last 2 decades, reviews of family power literature have been fundamentally shaped by the abiding interest in the relative power of men and women, rather than in power in the family per se. Researchers have continued to assume that family power is generated by acquiring skills, resources, and status outside the family rather than by acquiring skills for relating to others within the family. Much of the family power literature has focused on marriage and marital decision-making, but Kranichfeld argues that it is power within the parent-child relationship that is more complex, enduring, and significant. An understanding of the depth and reach of the kind of power that women hold, taken together without knowledge of how men's relationships to families are changing in our society, allows the possibility that women's positions are more secure than they sometimes seem. Many of the painful life situations that women experience because their powerlessness at a more macro level of society (desertion, physical abuse, teenage pregnancy) occur within the context of the romantic tie, and women's investment and power in vertical bonds are a source of support that reduces women's dependence on and vulnerability to the horizontal tie. Women occupy positions at the very center of the family, in contrast to men, who are becoming increasingly isolated from the family. From this perspective, the normally male power to make the decision about what kind of car to buy or where to spend the family vacation is nearly reduced to insignificance. The message seems to be that when it comes to securing family power, nothing can substitute for investment, attention, connection, and care.

  9. Reprogramming of microRNAs by adenosine-to-inosine editing and the selective elimination of edited microRNA precursors in mouse oocytes and preimplantation embryos.

    PubMed

    2013-05-01

    Adenosine deaminases-acting-on-RNA (ADAR) proteins induce adenosine-to-inosine editing in double-stranded RNA molecules. This editing generates RNA diversity at the post-transcriptional level, and it has been implicated in the control of cell differentiation and development. The editing of microRNA (miRNA) precursors, along with Tudor-SN (Snd1) activity, could lead to the elimination of selected miRNAs and reprogram miRNA activity. Here, we report the dynamics of adenosine-to-inosine editing in miRNA precursors and their selected elimination during mouse preimplantation development. Adar1p110 and Snd1 were found to be strongly but differentially expressed in oocytes and zygotes with respect to later pre-implantation stages. When the biogenesis of miR-151 was assessed, the majority of miR-151 precursors was edited and subsequently eliminated during early development. Deep sequencing of this and other miRNAs confirmed that, in general, edited precursors were selectively eliminated at early post-zygotic stages. Moreover, in oocytes and throughout the zygote-to-blastocyst stages, Tudor-SN accumulated in newly discovered aggregates termed 'T bodies'. These results provide new insight into how editing and Tudor-SN-mediated elimination of miRNA precursors is regulated during early development.

  10. Crystallization and X-ray diffraction analysis of the Trp/amber editing site of hepatitis delta virus (+)RNA: a case of rational design

    SciTech Connect

    MacElrevey, Celeste; Wedekind, Joseph E.

    2005-12-01

    Well diffracting decamer crystals of the hepatitis delta virus RNA-editing site were prepared, but exhibited merohedral twinning and base averaging owing to duplex symmetry. A longer asymmetric construct that includes additional flanking RNA sequences has been crystallized that does not appear to exhibit these defects. RNA editing by mammalian ADAR1 (Adenosine Deaminase Acting on RNA) is required for the life cycle of the hepatitis delta virus (HDV). Editing extends the single viral open reading frame to yield two protein products of alternate length. ADARs are believed to recognize double-stranded RNA substrates via a ‘structure-based’ readout mechanism. Crystals of 10-mer duplexes representing the HDV RNA-editing site diffracted to 1.35 Å resolution, but suffered from merohedral twinning and averaging of the base registry. Expansion of the construct to include two flanking 3 × 1 internal loops yielded crystals in the primitive tetragonal space group P4{sub 1}2{sub 1}2 or P4{sub 3}2{sub 1}2. X-ray diffraction data were collected to 2.8 Å resolution, revealing a unit cell with parameters a = 62.5, c = 63.5 Å. The crystallization and X-ray analysis of multiple forms of the HDV RNA-editing substrate, encounters with common RNA crystal-growth defects and a strategy to overcome these problems are reported.

    Our knowledge of the variety and abundances of RNA base modifications is rapidly increasing. Modified bases have critical roles in tRNAs, rRNAs, translation, splicing, RNA interference, and other RNA processes, and are now increasingly detected in all types of transcripts. Can new biological principles associated with this diversity of RNA modifications, particularly in mRNAs and long non-coding RNAs, be identified? This review will explore this question by focusing primarily on adenosine to inosine (A-to-I) RNA editing by the adenine deaminase acting on RNA (ADAR) enzymes that have been intensively studied for the past 20 years and have a wide range of effects. Over 100 million adenosine to inosine editing sites have been identified in the human transcriptome, mostly in embedded Alu sequences that form potentially innate immune-stimulating dsRNA hairpins in transcripts. Recent research has demonstrated that inosine in the epitranscriptome and ADAR1 protein establish innate immune tolerance for host dsRNA formed by endogenous sequences. Innate immune sensors that detect viral nucleic acids are among the readers of epitranscriptome RNA modifications, though this does preclude a wide range of other modification effects. PMID:26658668

    Caring for a family during pregnancy and birth is an ideal opportunity for family physicians to assess family functioning and help the family adjust to the birth of a new child. Stress and support systems can influence the course of pregnancy, including obstetric and perinatal outcomes. A family-centered approach can help patients during this critical stage of family development. PMID:21229107

  13. Strengthening family systems.

    Starn, J

    1993-01-01

    The childbearing year is a psychosocial transition that involves changes in roles and status for each member of the family. This change is perhaps most significant in the transition that occurs with the birth of the first child. Thus, childbirth education can be looked upon as an opportunity to strengthen family systems through anticipatory guidance and skill building that family members may use throughout the life cycle.

    Family planning and reproductive health services are uniquely impacted by policy and politics in the United States. Recent years have witnessed an unprecedented number of abortion restrictions, and research funding has decreased in related areas. Despite this, both the science and the implementation of improved family planning and abortion methods have progressed in the past decade. This article reviews the current state of family planning, as well as technologies and patient care opportunities for the future. PMID:25860324

    2015-09-01

    A new family classification, based on a catalog of proper elements with ∼384,000 numbered asteroids and on new methods is available. For the 45 dynamical families with >250 members identified in this classification, we present an attempt to obtain statistically significant ages: we succeeded in computing ages for 37 collisional families. We used a rigorous method, including a least squares fit of the two sides of a V-shape plot in the proper semimajor axis, inverse diameter plane to determine the corresponding slopes, an advanced error model for the uncertainties of asteroid diameters, an iterative outlier rejection scheme and quality control. The best available Yarkovsky measurement was used to estimate a calibration of the Yarkovsky effect for each family. The results are presented separately for the families originated in fragmentation or cratering events, for the young, compact families and for the truncated, one-sided families. For all the computed ages the corresponding uncertainties are provided, and the results are discussed and compared with the literature. The ages of several families have been estimated for the first time, in other cases the accuracy has been improved. We have been quite successful in computing ages for old families, we have significant results for both young and ancient, while we have little, if any, evidence for primordial families. We found 2 cases where two separate dynamical families form together a single V-shape with compatible slopes, thus indicating a single collisional event. We have also found 3 examples of dynamical families containing multiple collisional families, plus a dubious case: for these we have obtained discordant slopes for the two sides of the V-shape, resulting in distinct ages. We have found 2 cases of families containing a conspicuous subfamily, such that it is possible to measure the slope of a distinct V-shape, thus the age of the secondary collision. We also provide data on the central gaps appearing in

  1. Feminism and family therapy.

    PubMed

    Goldner, V

    1985-03-01

    Feminism has had a profound effect on contemporary culture and on thinking in most academic fields, including psychoanalysis. Interestingly, until very recently it had made virtually no impact on the theory and practice of family therapy. This paper proposes an explanation for this peculiar phenomenon and argues that family therapy has been considerably handicapped by its insularity from the feminist critique. Utilizing feminist scholarship in psychoanalysis, history, and sociology, the paper analyzes the structural contradictions in family life that family therapists have essentially ignored and then outlines their clinical implications. Key points in the discussion include the argument that systems theory is an inadequate explanatory matrix from which to build a theory of the family, that the archetypal "family case" of the overinvolved mother and peripheral father is best understood, not as a clinical problem, but as the product of a historical process two hundred years in the making, and that power relations between men and women in families function in terms of paradoxical, incongruous hierarchies that reflect the complex interpenetration between the structure of family relations and the world of work. This conceptual model then provides the basis for an analysis and critique of sexual politics as they emerge in the prototypical clinical situation.

    The author agrees with the United Teheran Declaration of Human Rights which declared the right of each couple to choose the size of their own family. Government policies must preserve and increase informed choice for all couples. The Supreme Court recognized the right of all married couples to practice birth control in a 1965 decision; the Court extended this right to all persons in 1972. The 1970 Family Planning Services and Population Research Act involved the United States government in family planning support here and abroad. By 1973 organized family planning programs were serving more than 3.2 million women. They had been extended geographically too. Fertility research is being conducted. Before 1980 family planning programs will be integrated into general health care systems with comprehensive health care insurance covering the bills.

    2014-01-01

    Background 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 emotions. Forms of psychosocial intervention, designed to reduce these levels of expressed emotions within families, are now widely used. Objectives To estimate the effects of family psychosocial interventions in community settings for people with schizophrenia or schizophrenia-like conditions compared with standard care. Search strategy We updated previous searches by searching the Cochrane Schizophrenia Group Trials Register (September 2008). Selection criteria We selected randomised or quasi-randomised studies focusing primarily on families of people with schizophrenia or schizoaffective disorder that compared community-orientated family-based psychosocial intervention with standard care. Data collection and analysis We independently extracted data and calculated fixed-effect relative risk (RR), the 95% confidence intervals (CI) for binary data, and, where appropriate, the number needed to treat (NNT) on an intention-to-treat basis. For continuous data, we calculated mean differences (MD). Main results This 2009-10 update adds 21 additional studies, with a total of 53 randomised controlled trials included. Family intervention may decrease the frequency of relapse (n = 2981, 32 RCTs, RR 0.55 CI 0.5 to 0.6, NNT 7 CI 6 to 8), although some small but negative studies might not have been identified by the search. Family intervention may also reduce hospital admission (n = 481, 8 RCTs, RR 0.78 CI 0.6 to 1.0, NNT 8 CI 6 to 13) and encourage compliance with medication (n = 695, 10 RCTs, RR 0.60 CI 0.5 to 0.7, NNT 6 CI 5 to 9) but it does not obviously affect the tendency of individuals/families to leave care (n = 733, 10 RCTs, RR 0.74 CI 0.5 to 1.0). Family intervention also seems to improve general social impairment and the levels of

    PubMed Central

    Plank, S J

    1978-01-01

    Family allowances designed to promote maternal and child health and welfare could be self-defeating if they stimulated otherwise unwanted births, as often assumed. That assumption, with its public health and demographic implications, needs testing. An attempt to test it was made in Chile in 1969--1970 through interviews with 945 wives receiving an allowance and 690 non-recipients. Recipients practiced contraception significantly more than did non-recipients. This was not explained by wives' educational attainment or employment, the couples' earnings, or number of living children, but was associated with a 50 per cent greater utilization of professional prenatal care by recipients during the most recent pregnancy; women with such care (regardless of allowance status) were 75 per cent more likely than others to control their fertility. Prenatal care was probably sought more by recipients in part because an additional stipend was provided as soon as pregnancy was confirmed, usually at clinics with integrated family planning. Greater family income, attributable to the allowance, probably also contributed to the recipients' better prenatal attention and to contraceptive practice. Noteworthy, too, was the finding that with the number of living children controlled, contraceptive practice was significantly greater amoung couples who had never lost a child. PMID:717610

    Current practices of obstetrical care tend to hinder rather than facilitate family development and maturation. A program of family centred maternity care is described. Husbands are invited to prenatal visits, and are involved in intensive preparation for labor and delivery. Their presence and active participation in labor, delivery, and postpartum course are encouraged. This, along with a rooming-in policy for the baby, and the utilization of the postpartum period for an intensive training in parenthood, appears to produce a safe and satisfying obstetrical experience for the family.

    PubMed Central

    Polson, Andrew G.; Ley, Herbert L.; Bass, Brenda L.; Casey, John L.

    1998-01-01

    RNA editing at adenosine 1012 (amber/W site) in the antigenomic RNA of hepatitis delta virus (HDV) allows two essential forms of the viral protein, hepatitis delta antigen (HDAg), to be synthesized from a single open reading frame. Editing at the amber/W site is thought to be catalyzed by one of the cellular enzymes known as adenosine deaminases that act on RNA (ADARs). In vitro, the enzymes ADAR1 and ADAR2 deaminate adenosines within many different sequences of base-paired RNA. Since promiscuous deamination could compromise the viability of HDV, we wondered if additional deamination events occurred within the highly base paired HDV RNA. By sequencing cDNAs derived from HDV RNA from transfected Huh-7 cells, we determined that the RNA was not extensively modified at other adenosines. Approximately 0.16 to 0.32 adenosines were modified per antigenome during 6 to 13 days posttransfection. Interestingly, all observed non-amber/W adenosine modifications, which occurred mostly at positions that are highly conserved among naturally occurring HDV isolates, were found in RNAs that were also modified at the amber/W site. Such coordinate modification likely limits potential deleterious effects of promiscuous editing. Neither viral replication nor HDAg was required for the highly specific editing observed in cells. However, HDAg was found to suppress editing at the amber/W site when expressed at levels similar to those found during HDV replication. These data suggest HDAg may regulate amber/W site editing during virus replication. PMID:9528763

    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.

    This article summarizes and illustrates the collaboration strategies used by several family therapies. The strategies used within multisystemic therapy (MST) are emphasized because it has demonstrated high rates of treatment completion and favorable outcomes in multiple clinical trials. Many of the collaboration strategies in family work are common to other forms of evidence-based psychotherapy (e.g., reflective listening, empathy, reframing, and displays of authenticity and flexibility); however, some strategies are unique to family systems treatments, such as the identification of strengths across multiple systems in the youth’s social ecology and the maintenance of a family (versus a child) focus during treatment. A case example illustrates collaboration and engagement in the context of MST. PMID:23616297

    This Bulletin documents recent changes in American family patterns resulting both from longterm trends in urbanization, industrialization, and economic growth and the disruption of the Great Depression and World War 2, as well as changed attitudes toward marriage, parenthood, divorce, and the roles of women. Following a postwar boom in the 1950s and 1960s, marriage rates have now fallen to levels observed in the early 20th century. Since 1970, the number of unmarried couples living together has more than tripled to 1.9 million in 1983. The divorce rate has now stabilized after more than doubling since 1960, but at the current level, 1/2 of all recent marriages will end in divorce. Most divorced persons remarry fairly quickly, often creating complex families of "step-relatives." With 19% of households with minor children now headed by a women with no husband present, up to 1/2 of all children will live for sometime in a fatherless family before age 18. Over 1/2 of all married women, including 49% of married mothers of preschool children, now hold a paid job outside the home. Working wives boost a family's income by an average 40% but still are expected to shoulder most responsiblility for home and childcare. White women now in their 20s say they expect to have an average of 2 children, but are delaying childbearing to such an extent that 29% could end up childless. Most of the elderly live on their own but usually near children whom they see frequently. Despite changes in traditional family patterns, Americans consistently report that a happy marriage and good family are the most important aspects of life. And though most Americans now live with few or no family members, they maintain active contact with a large network of family.

    The quality and efficiency in the process of psychological counseling with migrant families depends on the counselor's insight in the constellations of migration and culture. Both have a special influence on the way of coping with problems and the relation between client and counselor during the therapy. It is therefore necessary to adapt the own therapeutical approach to the migrant's experiences and abilities of comprehension. The author presents one example of intercultural family counseling by three short case explorations. PMID:11382173

    PubMed

    1980-12-01

    Until 1958, when the World Bank Economic Mission reported that Thailand's high rate of population growth was adversely affecting its development efforts, Thailand had a pronatalist policy. Government concern led to a formal declaration of voluntary family planning support in 1970. The National Family Planning Program (NFPP) under the auspices of the Ministry of Public Health has the following objectives: reduce the population growth rate to 2.5% per annum by the end of 1976; inform and motivate women about family planning, using methods of mass communication; increase availability of family planning services throughout the country; and to integrate family planning activities with maternal and child health services. Activities include training and supervision of NFPP personnel, research and evaluation, and the coordination of public and private family planning organizations. The NFPP has been successful in reducing the growth rate to 2.55% in 1976 and in surpassing its target contraceptive acceptor level of 1,975,000 to a level of 2,490,850. Future concerns of NFPP include its dependence on foreign financial support, and its need to encourage local funding.

  12. Familial pituitary tumors.

    Alband, Neda; Korbonits, Márta

    2014-01-01

    Pituitary adenomas are benign intracranial neoplasms that present a major clinical concern due to hormone overproduction and/or tumor mass effects. The majority of pituitary adenomas occur sporadically; however, familial cases are increasingly being recognized, such as multiple endocrine neoplasia type 1 (MEN1), Carney complex (CNC), and familial isolated pituitary adenoma (FIPA). Familial pituitary tumors appear to differ from their sporadic counterparts both in their genetic basis and in clinical characteristics. Evidence suggests that, especially in MEN1 and FIPA, tumors are more aggressive and affect patients at a younger age, therefore justifying the importance of early diagnosis, while in Carney complex pituitary hyperplasia is common. The genetic alterations responsible for the formation of familial pituitary syndromes include the MEN1 gene, responsible for about 80% of MEN1 cases, the regulatory subunit of the protein kinase A, PRKAR1A, responsible for about 70% of Carney complex cases, and AIP, the gene coding the aryl hydrocarbon receptor interacting protein, responsible for about 20% of FIPA cases. Rarely other genes have also been found responsible for familial pituitary adenoma cases. McCune-Albright syndrome (MAS) also has a genetic origin due to mosaic mutations in the G protein-coupled α subunit coded by the GNAS1 gene. In this chapter, we summarize the genetic and clinical characteristics of these familial pituitary syndromes and MAS. PMID:25248598

  13. Mandolin Family Instruments

    NASA Astrophysics Data System (ADS)

    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.

    Family-centered rehabilitation programs are derived from a philosophy of heath care delivery known as family-centered care. The principles of family-centered care are presented with clinical examples. Its origins are reviewed, and the 10-year process of implementation of family-centered care practice and policy at a children's rehabilitation center are described. Profound changes in behavior are required of the health care professionals as meaningful collaboration with families develops. Key elements of a family-centered rehabilitation program include meaningful participation by families in medical decision making and an institutional culture flexible enough to respond to the ongoing collaboration between families and practitioners.

  15. Changing families, changing workplaces.

    2011-01-01

    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

    We present clinical, pathological and molecular features of the first Austrian family with fatal familial insomnia. Detailed clinical data are available in five patients and autopsy in four patients. Age at onset of disease ranged between 20 and 60 years, and disease duration between 8 and 20 months. Severe loss of weight was an early symptom in all five patients. Four patients developed insomnia and/or autonomic dysfunction, and all five patients developed motor abnormalities. Analysis of the prion protein (PrP) gene revealed the codon 178 point mutation and methionine homozygosity at position 129. In all brains, neuropathology showed widespread cortical astrogliosis, widespread brainstem nuclei and tract degeneration, and olivary 'pseudohypertrophy' with vacuolated neurons, in addition to neuropathological features described previously, such as thalamic and olivary degeneration. Western blotting of one brain and immunocytochemistry in four brains revealed quantitative and regional dissociation between PrP(res)(the protease resistant form of PrP) deposition and histopathology. In the cerebellar cortex of one patient, PrP(res) deposits were prominent in the molecular layer and displayed a peculiar patchy and strip-like pattern with perpendicular orientation to the surface. In another patient, a single vacuolated neuron in the inferior olivary nuclei contained prominent intravacuolar granular PrP(res) deposits, resembling changes of brainstem neurons in bovine spongiform encephalopathy.

  18. Familial pancreatic cancer.

    PubMed

    2001-01-01

    Pancreatic cancer is the fourth leading cause of cancer death in both men and women in the United States and will be responsible for an estimated 28,900 deaths in 2001. Relatively little is known of its etiology, and the only well-established risk factor is cigarette smoking. Studies over the past 3 decades have shown that 4%-16% of patients with pancreatic cancer have a family history of the disease. A small fraction of this aggregation can be accounted for in inherited cancer syndromes, including familial atypical multiple-mole melanoma, Peutz-Jeghers syndrome, hereditary breast-ovarian cancer, hereditary pancreatitis, and hereditary nonpolyposis colorectal cancer. These syndromes arise as a result of germline mutations in the BRCA2, pl6 (familial atypical multiple-mole melanoma), mismatch repair (hereditary nonpolyposis colorectal cancer), and STK11 (Peutz-Jeghers syndrome) genes. In addition, hereditary plays a role in predisposing certain patients with apparently sporadic pancreatic cancer. Many patients with pancreatic cancers caused by a germline mutation in a cancer-causing gene do not have a pedigree that is suggestive of a familial cancer syndrome. A recent prospective analysis of the pedigrees in the National Familial Pancreatic Tumor Registry found that individuals with a family history of pancreatic cancer in multiple first-degree relatives have a high risk of pancreatic cancer themselves. The identification of such high-risk individuals will help clinicians target screening programs and develop preventive interventions with the hope of reducing the mortality of pancreatic cancer in these families.

  19. Family planning Indonesia.

    PubMed

    Singarimbun, M

    1968-06-01

    The growth of family planning activities in Indonesia in the Postwar period is traced; and future prospects for family planning are assessed. Transmigration projects initiated by the Dutch and supported by President Sukarno after Indonesian independence as a means of decreasing population pressure on the island of Java, are identified as the only official response to the population problem until 1965. In the face of the government's opposition to the idea of birth control as a population control measure, the activities of the Indonesian Planned Parenthood Association (IPPA) after its founding in 1957 were limited to advising mothers on spacing of their children for health reasons. Statements made in support of a national family planning program by government officials at a 1967 IPPA Congress and on other occasions are noted. The major components of an approved national family planning program to start in 1969 are described. However, the government's policy as of late 1967 and early 1968 is characterized as one of mainly benevolent encouragement and help to voluntary organizations. The chief impediment to family planning in Indonesia is said to be a lack of motivation and the force of traditional values that favor large families. On the positive side are: 1) Studies showing considerable interest in birth control by the rural population; 2) A long history of traditional birth control practices; 3) The absence of outright opposition by religious groups to the principle of family planning. However, financial costs, the need for the training of personnel, and a general unawareness of the magnitude of the task lying ahead constitute other formidable obstacles.

    1968-01-01

    Since the initial voluntary efforts of the Singapore Family Planning Association in 1949, family planning in Singapore has made important progress. This effort extended over the years until the end of 1965 when the government accepted full responsibility for family planning on a national scale. In September 1965, the government announced a 5-year National Family Planning Program with the goal of reducing the birthrate from 32/1000 in 1964 to below 20/1000 by 1970. This would result in a growth rate of not more than 1.5%. The government program aims at reaching 60% of married women in the reproductive age range of 15-45. It is estimated that out of 450,000 in this age range, some 300,000 are married. The target is 180,000 in 5 years. The Singapore Family Planning & Population Board was established by an Act of Parliament and charged with responsibility for the implementation of the 5-year plan. The national program offers a menu card of all family planning methods except abortion. Initial focus was on the IUD as the method of choice for 80%. Oral contraception (OC) was the preferred alternative for the remaining 20%. Other conventonal methods also were available. A few months after the plan began in 1966, the IUD became unacceptable to Singapore women. Its side effects of bleeding, cramps, perforation, and pregnancy were exaggerated by rumors. By the middle of 1966, attendance and acceptors in the national program had declined. Emphasis in the national program was changed to OCs, which now are the mainstay of family planning. Currently, nearly 65% of the acceptors use OCs. The program also demonstrates the importance, especially in urban areas, of the tremendous impact of a postpartum family planning service. Over 70% of the births in Singapore take place at the Kandang Kerbau Maternity Hospitals. Government midwives deliver another 5%. All these women are contacted by a team of family planning workers in the postpartum period and are offered family planning. Nearly

    Families have existed for thousands of years and are the most enduring form of small social group. This article discusses the family of Jacob as described in the Bible, and analyses the dynamics of the family system, the relationships between family members and the ways in which they interact and respond to stressful events. Such events disrupted the equilibrium of the family and led to a severe crisis, but this was eventually resolved peacefully and family members were reconciled. The story of Joseph, Jacob's son, unfolds as possibly the earliest description of a psychotherapeutic intervention to resolve a long-standing family crisis.

    Organizational and content features of various national family planning programs are reviewed. The Thai program is cited as an example of a family planning program organized on a massive unipurpose compaign basis. The Korean and Taiwan programs have utilized special field workers while upgrading the general health care network. 3 major problems with family planning programs are: 1) the lack of experience with such programs; 2) lack of commitment at the highest political levels; and 3) medical conservatism. Utilization of all available contraceptive methods instead of reliance on 1 method would improve most programs. Nursing and auxiliary personnel could be trained to take over the work of physicians in family planning programs. This is already being done with IUD insertion and pill prescription in several programs. The postpartum tubal ligation approach has proven effective and should be extended. There is a place in all national programs for both the private and the commercial sectors. Incentives for clinics, personnel, and acceptors might spread family planning more rapidly.

    Pituitary adenomas are benign intracranial neoplasms that present a major clinical concern because of hormonal overproduction or compression symptoms of adjacent structures. Most arise in a sporadic setting with a small percentage developing as a part of familial syndromes such as multiple endocrine neoplasia type 1 (MEN1), Carney complex (CNC), and the recently described familial isolated pituitary adenomas (FIPA) and MEN-4. While the genetic alterations responsible for the formation of sporadic adenomas remain largely unknown, considerable advances have been made in defining culprit genes in these familial syndromes. Mutations in MEN1 and PRKAR1A genes are found in the majority of MEN1 and CNC patients, respectively. About 15% of FIPA kindreds present with mutations of the aryl hydrocarbon receptor-interacting protein (AIP) gene. Mutations in the CDKN1B gene, encoding p27(Kip)¹ were identified in MEN4 cases. Familial tumours appear to differ from their sporadic counterparts not only in genetic basis but also in clinical characteristics. Evidence suggests that, especially in MEN1 and FIPA, they are more aggressive and affect patients at younger age, therefore justifying the importance of early diagnosis. In this review, we summarize the genetic and clinical characteristics of these familial pituitary adenomas. PMID:20961530

    We present a family study of multiple cavernomatosis which affected a boy of six, his mother and two brothers. It was seen clinically as epileptic crises, focal neurological defects and frequent headaches. In our case, the condition started as a syndrome of intracranial hypertension with progressive headache and vomiting. During the illness, localizing neurological signs due to bleeding were seen. Amongst these were acute left hemiparesia and paralysis of vertical gaze. Other members of the family remain symptom-free. In a search for angiomas at other sites none were found in the patient or his family. Recently the gene giving rise to the familial cerebral cavernosa malformation has been found to be a locus on chromosome 7. We discuss the findings on neuro-imaging, emphasizing the importance of magnetic resonance (MR) both in diagnosis and finding affected asymptomatic family members, because of its great sensitivity and specificity. Angiography is not a suitable technique for this since they behave as hidden malformations. We also point out its importance as a way of following-up the illness and for evaluation of possible complications due to progressive growth or sudden haemorrhage, which may indicate the need for treatment. Finally we emphasize the different characteristics of MR signals in this type of lesion since cavernomatasa malformations are dynamic lesions. PMID:9172920

    This qualitative study explores the dynamic changes that occur in family interaction patterns when Alzheimer's disease is present. Semi-structured interviews were conducted with 15 participants who have a family member with the disease. Using modified analytic induction, guided by the dimensions of the Family Fundamental Interpersonal Relations Orientation (FIRO) Model, participants shared how Alzheimer's disease affected family structure, control dynamics, and intimacy among family members. Findings demonstrate that (a) families reorganize and restructure based on geographic proximity and shifting roles, act out of filial responsibility, and strive to preserve shared meanings and rituals; (b) decision making increases around care of the person with Alzheimer's disease and shifts to the primary caregiver or other family members based on their abilities; and (c) expressions of intimacy intensify while personality is preserved in the person with the disease. The Family FIRO model can inform practitioners using family-centered care with families with Alzheimer's disease.

    Because of support groups and studies on death, a new type of care for bereaved parents has been crafted over the past several decades. Support groups and medical professionals are key to this type of care. For medical professionals this job is difficult at times since individual needs may differ. But by following some basic guidelines, medical professionals can help the parents start the recovery process for they are the ones in contact with the parents at the time of death. The guidelines include giving the families complete medical information, reassurance and a chance to talk. Also, importantly, this care includes treating the baby and family with dignity and acknowledging the magnitude of the loss. In Japan most bereaved parents still go completely unassisted at the time of their baby's death. Formation of support groups and a greater awareness by medical professionals on how to care for these families will solve this problem.

    1992-01-01

    In 1991, an HIV prevention program advisor and a research/evaluation specialist for family planning programs discussed problems that affected HIV prevention and family planning services in Haiti before and after the coup of the Aristide government. Population activities began aimlessly in 1974 and HIV prevention efforts only began in 1988. After the coup, Haitians lost their newly found hope for meaningful development. All foreign assistance ended and they did not trust the army. In fact, other than essential child survival activities, no health and family planning services operated for several weeks. The situation grew worse after the economic embargo. 3 months after the coup, the US considered adding family planning assistance. Still little movement of condom, family planning, and health supplies left Port-au-Prince for the provinces which adversely affected all health related efforts. Condoms could no longer be distributed easily either in the socially marketed or US supplied condom distribution programs. Before the coup, HIV prevention and family planning programs depended on peer educators to educate the public (this approach made these programs quite successful), but the 2 experts feared that they would not return to those roles and that these programs would need to completely rebuild. Another concern was the large scale urban-rural migration making it difficult for them to continue care. Early in the AIDS epidemic, the Haitian government was on the defensive because the US considered Haitians as a high risk group so it did little to prevent HIV transmission. After 1988, HIV prevention activities in Haiti centered on raising awareness and personalizing the epidemic. The AIDS specialist noted, however, that a major obstacle to increasing knowledge is that AIDS is just 1 of many fatal diseases in Haiti. Moreover few health professionals in Haiti have ever had public health training. PMID:12159262

    2011-01-01

    There are now three known causative genes for familial hemiplegic migraine and increasing evidence to support a genetic predisposition to the more common types of migraine with and without aura, and for cluster headache. We present the first reported case of familial hemicrania continua. A mother and daughter developed hemicrania continua at the same time of life. Both showed an absolute response to indometacin and at similar doses. Both also suffered from migraine with aura. We discuss the increasing support for a genetic predisposition to dysfunction of the pain system within the brain manifesting as primary headache.

  4. Family-witnessed resuscitation.

    PubMed

    Boucher, Melanie

    2010-09-01

    Family-witnessed resuscitation is a controversial subject for healthcare professionals and support for the practice is not universal (Albarran and Stafford 1999, Kissoon 2006). Research suggests, however, that the advantages of this form of resuscitation for relatives far outweigh the disadvantages, and that hospital staff can support the practice without hindering the clinical care of patients. This article explores the ethical issues raised, as well as the views of patients, families and staff on the subject, and suggests that there should be guidelines on the practice in all emergency departments where it is likely to take place.

    SciTech Connect

    Siraganian, P.A.; Mulvihill, J.J.; Mulivor, R.A.; Miller, R.W. )

    1989-03-03

    Elevated alkaline phosphatase activity in serum suggests bone or liver disease or a neoplasm but can also indicate pregnancy or another benign condition. A family with benign hyperphosphatasemia was studied to elucidate the genetics and enzyme defect. Serum total alkaline phosphatase activity was greater than the population mean in all six family members, and more than 7 SDs above the mean in two of four offspring. Monoclonal antibodies to three alkaline phosphatase isoenzymes, intestinal, placental, and tissue nonspecific demonstrated markedly increased intestinal alkaline phosphatase levels in all family members and significantly elevated liver/bone/kidney activity in the two offspring. Guanidine hydrochloride denaturation of the liver/bone/kidney component showed high alkaline phosphatase activity from liver in both siblings and from bone in one. The mode of inheritance in this family is obscure, but a complex regulation of the products of two different alkaline phosphatase genes seems likely. Steps toward diagnosis are suggested. Early recognition of this benign biochemical abnormality should help to avoid unnecessary diagnostic tests.

    PubMed

    Hansson, Johan

    2010-01-01

    Approximately 5-10 % of all cutaneous melanomas occur in families with hereditary melanoma predisposition. Worldwide, approximately 20-40% of kindreds with familial elanoma harbor germline mutations in the CDKN2A gene, located on chromosome 9p21, which encodes two different proteins, p16INK4 and p14ARF, both involved in regulation of cell cycle progression and induction of senescence. In different populations several recurring CDKN2A founder mutations have been described. The risk of melanoma in CDKN2A mutations carriers varies between populations and is higher in regions with high sun exposure and high incidence of melanoma in the general population. Some CDKN2A mutations have been associated not only with melanoma but also with increased risk of other malignancies--most notably pancreatic carcinoma. A much smaller number of families have germline mutations in the CDK4 gene on chromosome 12q14, encoding a cyclin dependent kinase which normally interacts with p16INK4A. The management of families with hereditary melanoma is discussed. PMID:20687502

    2016-01-01

    Abstract Familial gigantiform cementoma is an exceedingly rare but distinct subtype of cemento-osseous-fibrous lesion. Undocumented radiographic changes and related bone metabolism disorder are herein hypothesized and discussed. We present an adolescent case with recurrent familial gigantiform cementoma who received surgical intervention in our hospital. Apart from typical multiquadrant and expansile abnormalies involving both jaws, he also suffered from several times of fractures in lower extremity. Furthermore, radiographic examinations of calvaria, pelvis, femoris, tibia, and fibula all revealed radiolucent areas signifying diffuse osteopenic bone losses. Some of his consanguineous relatives bore the same burden of fractures during pubertal period. Considering these polyostotic conditions, a correlation of congenital bone metabolism disorder in cases with familial gigantiform cementoma, named “calcium steal disorder,” was thus proposed. Familial gigantiform cementoma is closely associated with “calcium steal disorder.” Whole-body dual-energy absorptiometry should be considered as a routine examination for fracture-related risk prediction.

    This special issue contains a section on the family in Brazil with two articles. The first, by Ana M. Goldani, examines how family characteristics in Brazil have changed since 1981 in response to the economic crises that have affected the country. The author uses census and survey data to analyze the relations between demographic trends and family characteristics. Particular attention is given to the growth of non-nuclear families, such as one-parent families. The second, by Dominique Fougeyrollas-Schwebel, also looks at changes in the family in Brazil, with particular reference to changes in women's work both within the family and in the work force.

  1. India's misconceived family plan.

    PubMed

    Jacobson, J L

    1991-01-01

    India's goal of reducing the national birth rate by 50% by the year 2000 is destined to failure in the absence of attention to poverty, social inequality, and women's subordination--the factors that serve to perpetuate high fertility. There is a need to shift the emphasis of the population control effort from the obligation of individual women to curtail childbearing to the provision of the resources required for poor women to meet their basic needs. Female children are less likely to be educated or taken for medical care than their male counterparts and receive a lower proportion of the family's food supply. This discrimination stems, in large part, from parents' view that daughters will not be able to remunerate their families in later life for such investments. The myth of female nonproductivity that leads to the biased allocation of family resources overlooks the contribution of adult women's unpaid domestic labor and household production. Although government statistics state that women comprise 46% of India's agricultural labor force (and up to 90% of rural women participate in this sector on some basis), women have been excluded systematically from agricultural development schemes such as irrigation projects, credit, and mechanization. In the field of family planning, the Government's virtually exclusive focus on sterilization has excluded younger women who are not ready to terminate childbearing but would like methods such as condoms, diaphragms, IUDs, and oral contraceptives to space births. More general maternal-child health services are out of reach of the majority of poor rural women due to long distances that must be travelled to clinics India's birth rate could be reduced by 25% by 2000 just by filling the demand for quality voluntary family planning services. Without a sustained political commitment to improve the status of women in India, however, such gains will not be sustainable.

  2. [Return to the family].

    PubMed

    Ouaidou, N G

    1993-08-01

    Sahelian countries occupy an inglorious place in the global list of human development. The human development index is superior to the gross national product (GNP) at measuring the progress of a country in terms of development, because it includes income, longevity, and educational level. The highest ranked Sahelian country holds the 114th position out of a 173 countries. The low human development index scores for the Sahel reflects the socioeconomic crisis which has overcome these countries. In 1991, only 3 of 9 Sahelian countries had a mean GP equal or superior to US$500. Just 2 countries had a life expectancy greater than 50 years. In fact, the Sahel had a lower life expectancy than all of Africa (50 years) and much lower than Asia (64 years) and Latin America (67 years). The economic crisis is worse than the cold statistics show. It destabilizes the most disadvantaged populations. The pressure it exerts often leads public authorities to adopt unpopular measures. It depreciates some sociocultural values and disintegrates traditional social structures. It is accentuated by the effects of war and drought. Internal and external migration increases even as urban hope is uncertain. For most people, the family (the traditional framework of individual development) is ready to break apart, leaving only a disincarnate nuclear entity to subsist. Yet, African history is built around the extended family: the place of reproduction, production, distribution, formation, management, perpetuation of demographic behavior, and social control. Senegal and Mali have created ministries which invest in families. The Third African Conference on Population, in 1992, chose its theme to be the relationship between family, population, and sustainable development. It is important to return to the natural or primordial framework--family--as a refuge against the economic crisis. PMID:12318645

    Psychological distress, marital satisfaction, family adaptability, and cohesion are explored in 31 families with mentally retarded (MR) institutionalized offspring (late adolescence and young adulthood) and 38 comparison families. Multivariate analyses indicate no differences between the groups, although univariate analyses point to higher levels of cohesion in the families with MR offspring and the importance of the construct of adaptability in understanding family functioning. The results are discussed in terms of the adaptive coping mechanisms of the families with MR offspring and the implications of this for intervention, research, and policy.

  5. The family and family medicine: should this marriage be saved?

    PubMed

    Merkel, W T

    1983-11-01

    Although there have been many noteworthy attempts to integrate a family focus into family medicine, there is little evidence that this integration has occurred in either residency education or community practice. When the specialty was founded, a family emphasis may have been politically useful as a way to differentiate the new family physician from the old general practitioner. Now, however, it is unclear what specific family-related material should be taught or who should teach it since few family practice faculty are trained in understanding families. If a practicing family physician actually wants to see a family, practical problems concerning time, space, and money arise. Furthermore, the medicolegal system is structured to protect the confidential relationship between one patient and one physician. Other obstacles to the integration include the difficult epistemological shift required to apply systems theory, the current chaos in the family field, and family medicine's need to gain professional stature by being proficient in traditional medicine. It may be time for the family and family medicine to reconsider their well-intended but ill-advised relationship. PMID:6631349

    PubMed

    2013-09-01

    We draw upon family resilience and narrative theory to describe an evidence-based method for intervening with military families who are impacted by multiple wartime deployments and psychological, stress-related, or physical parental injuries. Conceptual models of familial resilience provide a guide for understanding the mechanics of how families respond and recover from exposure to extreme events, and underscore the role of specific family processes and interaction patterns in promoting resilient capabilities. Leading family theorists propose that the family's ability to make meaning of stressful and traumatic events and nurture protective beliefs are critical aspects of resilient adaptation. We first review general theoretical and empirical research contributions to understanding family resilience, giving special attention to the circumstances, challenges, needs, and strengths of American military families. Therapeutic narrative studies illustrate the processes through which family members acquire meaning-making capacities, and point to the essential role of parents' in facilitating discussions of stressful experiences and co-constructing coherent and meaningful narratives. This helps children to make sense of these experiences and develop capacities for emotion regulation and coping. Family-based narrative approaches provide a structured opportunity to elicit parents' and children's individual narratives, assemble divergent storylines into a shared family narrative, and thereby enhance members' capacity to make meaning of stressful experiences and adopt beliefs that support adaptation and growth. We discuss how family narratives can help to bridge intra-familial estrangements and re-engage communication and support processes that have been undermined by stress, trauma, or loss. We conclude by describing a family-based narrative intervention currently in use with thousands of military children and families across the USA.

    Microrchidia (MORC) is a highly conserved nuclear protein superfamily with widespread domain architectures that intimately link MORCs with signaling-dependent chromatin remodeling and epigenetic regulation. Accumulating structural and biochemical evidence has shed new light on the mechanistic action and emerging role of MORCs as epigenetic regulators in diverse nuclear processes. In this Point of View, we focus on discussing recent advances in our understanding of the unique domain architectures of MORC family of chromatin remodelers and their potential contribution to epigenetic control of DNA template-dependent processes such as transcription and DNA damage response. Given that the deregulation of MORCs has been linked with human cancer and other diseases, further efforts to uncover the structure and function of MORCs may ultimately lead to the development of new approaches to intersect with the functionality of MORC family of chromatin remodeling proteins to correct associated pathogenesis.

  8. Balancing Family and Career

    In essentially all countries, responsibilities for child care, cooking, cleaning, and other homemaking tasks fall predominantly on the wife and mother. In addition, the childbearing years come during the period when a physicist must study hard, work long hours on research, and take temporary positions, often abroad. Thus, balancing family and career has long been one of the major barriers to women's participation in science and engineering fields, including physics. While many young women believe that they must choose between having children and having a science career, the fact is that the majority of women physicists in both developing and developed countries have successfully done both. This paper summarizes some ideas and recommendations raised in discussions, especially focused on easing the challenges of having children while in temporary jobs, returning to physics after a career break, the need for "family-friendly" working conditions, and the dual-career problem facing couples where both are scientists.

    Cleidocranial dysplasia or mutational dysostosis or cleidocranial dysostosis is a generalized skeletodental dysplastic disorder, inherited in an autosomal dominant pattern. The expression of this disorder can vary widely in severity, even within the same family. This is a relatively rare disease and has no standard effective treatment option as of yet. Here we present a case report of affected mother and son with classical manifestations of the disease.

  12. Family planning: where now?

    PubMed

    Saunders, L

    1977-01-01

    The focus is in terms of family planning as an exercise in induced social change; the objective is to alter the reproductive patterns of societies sufficiently to bring about a significant reduction in fertility. The year 1974 emerges as the year in which family planning as a social movement achieved maturity and was confirmed as a legitimate area for national policy and programming, a year of determined and varied efforts to reduce population growth. In affirming the rights and responsibilities of people and the obligations of governments in population concerns, the Bucharest Conference conferred its seal of approval on a movement that had made considerable progress since it began early in the 19th century. The evolution of birth control as a social movement which began with Francis Place's printing and distributing contraceptive bills in 1820 was encouraged by other writings in England and the U.S. over the next 50 years. Several overlapping phases can be distinguished in the global response to a new sense of urgence regarding population concerns following World War 2. Moving from a global perspective to consideration of family planning as it exists in the programs of individual countries, the achievement is not so great and the prospects are less hopeful. Although it has had success as a social movement and is now accepted as a government responsibility, family planning programs still have a long way to go before they develop the scope, vigor, and versatility that is required for there to be widespread demographic change. 1 change that is needed is for a stronger and more visible political commitment and commitment on the basis of demographic rather than health or welfare reasons.

  14. Sibling similarity in family formation.

    Raab, Marcel; Fasang, Anette Eva; Karhula, Aleksi; Erola, Jani

    2014-12-01

    Sibling studies have been widely used to analyze the impact of family background on socioeconomic and, to a lesser extent, demographic outcomes. We contribute to this literature with a novel research design that combines sibling comparisons and sequence analysis to analyze longitudinal family-formation trajectories of siblings and unrelated persons. This allows us to scrutinize in a more rigorous way whether sibling similarity exists in family-formation trajectories and whether siblings' shared background characteristics, such as parental education and early childhood family structure, can account for similarity in family formation. We use Finnish register data from 1987 through 2007 to construct longitudinal family-formation trajectories in young adulthood for siblings and unrelated dyads (N = 14,257 dyads). Findings show that family formation is moderately but significantly more similar for siblings than for unrelated dyads, also after controlling for crucial parental background characteristics. Shared parental background characteristics add surprisingly little to account for sibling similarity in family formation. Instead, gender and the respondents' own education are more decisive forces in the stratification of family formation. Yet, family internal dynamics seem to reinforce this stratification such that siblings have a higher probability to experience similar family-formation patterns. In particular, patterns that correspond with economic disadvantage are concentrated within families. This is in line with a growing body of research highlighting the importance of family structure in the reproduction of social inequality.

  12. Family planning for travellers.

    PubMed

    Rustom, A

    1990-11-01

    A public health nurse from London describes the customs of nomadic people in the British Isles, known as "travellers," as they affect provision of family planning services. Most are of British or Irish stock, some migrate and others live in caravan sites all year. Their traditions dictate that men work and women are housewives. Early, often arranged, marriage, early childbearing and large families are the norm. Sex and contraception are not considered appropriate for discussion between the sexes, or in the presence of children. Large families and financial hardship force many women to space pregnancies. Women often have to hide contraceptives from their husbands, difficult in conditions without privacy. Therefore they prefer IUDs, but some use oral contraceptives, although sometimes erratically because most are illiterate. Traveller women are usually unwilling to do self-examination, as needed with IUDs. They often have difficulty attending regular Pap smear clinics. Cervical cancer rates are high. They experience discrimination in clinics, and need extra care about modesty. It is worth while to take time to develop trust in the clinical relationship, to deal with the traveller woman's uneasy among outsiders.

  13. Nonclinical family planning programs.

    PubMed

    Bair, W D

    1978-01-01

    Reasons commonly advanced for providing family planning are the need for it as a health measure, as part of the basic human right of parents to plan their families, and as a measure to slow demographic growth. Provision of access to all couples desiring birth control, not just to the wealthy and educated, is a less frequently discussed reason. All these reasons require broad coverage in order to be effective. The author argues, using data on the relative health risks of contraceptive usage vs. pregnancy, that nonclinic distribution of contraceptives is consistent with responsible health considerations. The argument is buttressed by ethical considerations. The demand for family planning services is next considered, with the author arguing that availability of contraceptives is an important factor in increasing demand for them. The characteristics and users of nonclinic delivery systems are then discussed. Commercial distribution systems may provide services for up to 5% of women of fertile age, thus providing a useful supplement to organized and more highly subsidized programs. Noncommercial distribution -- household or community based systems -- has allowed contraceptive use to expand to levels of 20 or 25% and sometimes as high as 50%, in periods as short as a year and a half, at low cost. Community leaders have often proven to be more effective than clinic personnel in providing instruction and support to contraceptive users.

    1998-01-01

    The discussion opens with an account of the author's mother's bizarre family in which a strong, charismatic grandmother maintained absolute control over her large family by encouraging a neurotic dependence in them through daily reports of their complaints. Getting interested in psychoanalysis in an effort to understand the dynamics of this dysfunctional family, the author, a biographer, turned to the study of Melanie Klein, becoming entranced by her ideas. Her research also revealed how Klein had discouraged her followers from developing ideas that diverged in any way from her own. Her portrait of the pioneer analyst provoked intense indignation. A similar pattern of absolute loyalty to his person and theories was to be found in Freud's Secret Committee, formed primarily as a means of getting rid of Jung who had been showing disturbing signs of independence. When Ferenczi and Rank began to pursue independent lines of enquiry in their work, they too were though to be undermining the foundations of classical psychoanalysis. Finally, the author concludes that though there have been sorry incidents in psychoanalysis, we should be mature enough to accept both the contributions of the early pioneers and the realizations that new ideas must be permitted to evolve.

    A set of proposals to rationalize and extend the taxonomy of the family Parvoviridae is currently under review by the International Committee on Taxonomy of Viruses (ICTV). Viruses in this family infect a wide range of hosts, as reflected by the longstanding division into two subfamilies: the Parvovirinae, which contains viruses that infect vertebrate hosts, and the Densovirinae, encompassing viruses that infect arthropod hosts. Using a modified definition for classification into the family that no longer demands isolation as long as the biological context is strong, but does require a near-complete DNA sequence, 134 new viruses and virus variants were identified. The proposals introduce new species and genera into both subfamilies, resolve one misclassified species, and improve taxonomic clarity by employing a series of systematic changes. These include identifying a precise level of sequence similarity required for viruses to belong to the same genus and decreasing the level of sequence similarity required for viruses to belong to the same species. These steps will facilitate recognition of the major phylogenetic branches within genera and eliminate the confusion caused by the near-identity of species and viruses. Changes to taxon nomenclature will establish numbered, non-Latinized binomial names for species, indicating genus affiliation and host range rather than recapitulating virus names. Also, affixes will be included in the names of genera to clarify subfamily affiliation and reduce the ambiguity that results from the vernacular use of "parvovirus" and "densovirus" to denote multiple taxon levels.

    Family oriented innovative programs extend the reach of many traditional out-of-school venues to involve the entire family in learning in comfortable and fun environments. Research shows that parental involvement is key to increasing student achievement outcomes, and family-oriented programs have a direct impact on student performance. Because families have the greatest influence on children's attitudes towards education and career choices, we have developed a Family Science program that provides families a venue where they can explore the importance of science and technology in our daily lives by engaging in learning activities that change their perception and understanding of science. NASA Family Science Night strives to change the way that students and their families participate in science, within the program and beyond. After three years of pilot implementation and assessment, our evaluation data shows that Family Science Night participants have positive change in their attitudes and involvement in science.  Even after a single session, families are more likely to engage in external science-related activities and are increasingly excited about science in their everyday lives.  As we enter our dissemination phase, NASA Family Science Night will be compiling and releasing initial evaluation results, and providing facilitator training and online support resources. Support for NASA Family Science Nights is provided in part through NASA ROSES grant NNH06ZDA001N.

  7. Gender effects in familial cancer.

    Hemminki, Kari; Li, Xinjun

    2002-11-10

    Very limited data are available on sex ratios in familial cancer. Such data would be valuable in the assessment of sex chromosome effects and of interactions between background and familial rates. We used the nationwide Swedish Family-Cancer Database on 10.2 million individuals and over 1 million neoplasms to analyze familial risks for male and female offspring by paternal and maternal concordant cancer. Sex ratios for familial cancer were derived for cancer at 15 sites shared by men and women. At 14 sites the sex ratio (male/female) for familial relative risk ranged between 0.78 and 1.41, with no evidence of sex preference, suggesting that sex chromosomes do not contribute to a noticeable extent to familial risks. Furthermore, in cancers where the background incidence varied extensively by sex, such as bladder cancer (sex ratio 2.82) and nonthyroid endocrine tumors (0.65), the familial effect was proportionate to the background incidence and the familial sex ratio was close to unity. In thyroid cancer, the familial sex ratio was 2.48 (1.54-3.98) and the background incidence ratio was 0.31. This was the first evidence of an inverse sex ratio in primary cancer, i.e., higher familial risk in the gender of low background risk. The high familial ratio, 2.85 (95% CI: 1.35-6.03), was due to thyroid adenocarcinoma, encompassing both papillary and follicular types.

    2001-06-01

    We studied 15 families with autistics, 15 with Down's syndrome and 15 asymptomatic children. Patients' age ranged from 5 to 15 years-old. The parents of these three families' groups were appraised in regard to their family dynamics, to relate those symptoms to the functioning of an autistic family, in a comparative study. Details were provided of the families, the overall autistic features, the autistic's family, the family and the mental health, their limitations and difficulties throughout the vital cycle. An attempt was made to locate the factors that aid the family in hindering the healthy emotional development of its members. The field research was achieved by use of the instruments of the Family Dynamics Evaluation, (Carneiro, 1983). The data gathered were statistically compared. Considering the family population studied (n = 45), we found that the autistics' families and victims of Down's syndrome made it difficult to sustain the emotional health of group members. We conclude that the autistic's family dynamics caused difficulties to the emotional health of the group's members. PMID:11400032

  18. Family identity: black-white interracial family health experience.

    PubMed

    Byrd, Marcia Marie; Garwick, Ann Williams

    2006-02-01

    The purpose of this interpretive descriptive study was to describe how eight Black-White couples with school-aged children constructed their interracial family identity through developmental transitions and interpreted race to their children. Within and across-case data analytic strategies were used to identify commonalities and variations in how Black men and White women in couple relationships formed their family identities over time. Coming together was the core theme described by the Black-White couples as they negotiated the process of forming a family identity. Four major tasks in the construction of interracial family identity emerged: (a) understanding and resolving family of origin chaos and turmoil, (b) transcending Black-White racial history, (c) articulating the interracial family's racial standpoint, and (d) explaining race to biracial children across the developmental stages. The findings guide family nurses in promoting family identity formation as a component of family health within the nurse-family partnership with Black-White mixed-race families.

    Twenty years ago, the National Institute of Child Health and Human Development (NICHD) issued a request for proposals that resulted in the National Survey of Families and Households (NSFH), a unique survey valuable to a wide range of family scholars. This paper describes the efforts of an interdisciplinary group of family demographers to build on the progress enabled by the NSFH and many other theoretical and methodological innovations. Our work, also supported by NICHD, will develop plans for research and data collection to address the central question of what causes family change and variation. We outline the group's initial assessments of orienting frameworks, key aspects of family life to study, and theoretical and methodological challenges for research on family change. Finally, we invite family scholars to follow our progress and to help develop this shared public good. PMID:20376277

    1996-04-01

    Women in Thailand are increasingly finding themselves responsible for caring for the physical and mental health of HIV-infected men. The author gained such experience caring for her husband, while her suffering since youth of a series of chronic illnesses helped her to understand that life is full of surprises. Moreover, meditation also helps her to squarely confront problems as they arise, such as when she learned that she contracted HIV from her husband 5 years ago. The author then learned about AIDS and attended, together with her husband, conferences on HIV/AIDS to learn how to care for them both. She also enrolled in a Red Cross program on in-home care. In 1994, the husband returned home from the hospital in poor health, with little time left to live. However, surrounded by the warmth and affection of home, friends, and family, the man¿s health status improved to the extent that his opportunistic diseases disappeared. Since that experience, the author visits other households where people are living with AIDS in an attempt to bring them moral support, to teach about in-home care, and to coordinate hospital care when needed. The author now knows that HIV-seropositive people can contribute considerably to help the lives of both others living with AIDS and the general community. She is determined to show that families working together can reduce the level of suffering experienced by HIV-infected individuals and that such people will survive longer through families¿ efforts.

  2. The Hedgehog protein family.

    PubMed

    Bürglin, Thomas R

    2008-01-01

    The Hedgehog (Hh) pathway is one of the fundamental signal transduction pathways in animal development and is also involved in stem-cell maintenance and carcinogenesis. The hedgehog (hh) gene was first discovered in Drosophila, and members of the family have since been found in most metazoa. Hh proteins are composed of two domains, an amino-terminal domain HhN, which has the biological signal activity, and a carboxy-terminal autocatalytic domain HhC, which cleaves Hh into two parts in an intramolecular reaction and adds a cholesterol moiety to HhN. HhC has sequence similarity to the self-splicing inteins, and the shared region is termed Hint. New classes of proteins containing the Hint domain have been discovered recently in bacteria and eukaryotes, and the Hog class, of which Hh proteins comprise one family, is widespread throughout eukaryotes. The non-Hh Hog proteins have carboxy-terminal domains (the Hog domain) highly similar to HhC, although they lack the HhN domain, and instead have other amino-terminal domains. Hog proteins are found in many protists, but the Hh family emerged only in early metazoan evolution. HhN is modified by cholesterol at its carboxyl terminus and by palmitate at its amino terminus in both flies and mammals. The modified HhN is released from the cell and travels through the extracellular space. On binding its receptor Patched, it relieves the inhibition that Patched exerts on Smoothened, a G-protein-coupled receptor. The resulting signaling cascade converges on the transcription factor Cubitus interruptus (Ci), or its mammalian counterparts, the Gli proteins, which activate or repress target genes.

    More than 45% of women scientists at top universities in the United States have indicated that their careers have kept them from having as many children as they want, according to an 8 August study, “Scientists want more children,” which appears in the journal PLoS ONE. The study, by sociologists Elaine Howard Ecklund of Rice University and Anne Lincoln of Southern Methodist University, indicates that 24.5% of male scientists surveyed indicated the same concerns. The study also found that among junior scientists, 29% of women indicated concern that a science career would prevent them from having a family; 7% of men indicated the same concern.

    Since its introduction in 1994, SEQUEST has gained many important new capabilities, and a host of successor algorithms have built upon its successes. This Account and Perspective maps the evolution of this important tool and charts the relationships among contributions to the SEQUEST legacy. Many of the changes represented improvements in computing speed by clusters and graphics cards. Mass spectrometry innovations in mass accuracy and activation methods led to shifts in fragment modeling and scoring strategies. These changes, as well as the movement of laboratories and lab members, have led to great diversity among the members of the SEQUEST family.

    Nine members of a family spanning three generations showed bilateral calcifications of the basal ganglia with autosomal dominant inheritance. Two members developed chorea, dementia, and a characteristic speech disturbance (palialalia) in the third or fourth decade. A third member possibly shows the initial stage of a similar syndrome. Six members with calcifications but without neurological signs are younger than 25 years. All nine patients had normal calcium and phosphorus, and no evidence of endocrinological or somatic abnormalities. Thie 'isiopathic' picture must be differentiated from hypoparathyroidism and pseudohypoparathyroidism. Images PMID:886353

    Pediatric illnesses are always a family problem. Hospitalization, treatments and their long term consequences constitute a challenge for the family. In this paper, we describe the structural, procedural and emotional alterations that affect the family dynamic. We argue that the child should be treated within the family context and propose a multi-dimensional intervention model centered on the family's singularities and specific needs, the support available in their environment, the development of capacities and resilience, and also the organization of user-centered services that are coordinated with all the services provided by the community.

    1989-01-01

    The relationship between caregiver and elder is a unique one. It cannot be compared to a mother-infant dyad; there is no role reversal. Family caregiving is undertaken out of a sense of filial obligation on the family's part coupled with the needs of the elderly person. The relationship that emerges is based on the dependency of one adult on another and is functional for the family and for society at large. We need families to continue to care for their elderly members at home and families need us to insure their survival. We must constantly be aware that care needs increase over the years, whereas family resources do not. Nursing by its very nature is tied to insuring that families are given the guidance and assistance with which to meet these needs. PMID:2789693

    Asteroid families are clusters of asteroids in proper element space which are thought to be fragments from former collisions. Studies of families promise to improve understanding of large collision events and a large event can open up the interior of a former parent body to view. While a variety of searches for families have found the same heavily populated families, and some searches have found the same families of lower population, there is much apparent disagreement between proposed families of lower population of different investigations. Indicators of reliability, factors compromising reliability, an illustration of the influence of different data samples, and a discussion of how several investigations perceived families in the same region of proper element space are given.

    Alcatel Space has developed a new SADM family driven by cost, modularity, mass and performances. The modularity concept is based on separating the rotation drive function from the electrical transfer function. The drive actuator has been designed for various applications where pointing and reliability is needed. It can be associated with high dissipative rotary devices (SA collectors, RF joints..). The design goal was to minimize the number of parts in order to reach the most simple and compact mechanism. Mass reduction was achieved by reducing as much as possible the load path between the Solar Array interface and the spacecraft interface. Following these guidelines, the drive actuator was developed and qualified on ATV SADM (part od Alcatel Space Solar Array Drive Sub System for ATV). Further more a high power integrated collector was qualified inside the SADM for Geo-stationary telecom satellite (SPACEBUS platforms). Fine thermal and mechanical modeling was necessary to predict SADM behaviors for the numerous thermal environments over the missions (steady and transient cases). These modeling were well correlated through mechanical and thermal balances qualification tests. The challenging approach of thermal dissipation in a compact design leads to a family of 3 SADM capabilities form 2kW up to 15kW per SADM weighing less than 4.5 kg each.

    PubMed Central

    2014-01-01

    Familial hypercholesterolemia (FH) is a genetic disorder of lipoprotein metabolism resulting in elevated serum low-density lipoprotein (LDL) cholesterol levels leading to increased risk for premature cardiovascular diseases (CVDs). The diagnosis of this condition is based on clinical features, family history, and elevated LDL-cholesterol levels aided more recently by genetic testing. As the atherosclerotic burden is dependent on the degree and duration of exposure to raised LDL-cholesterol levels, early diagnosis and initiation of treatment is paramount. Statins are presently the mainstay in the management of these patients, although newer drugs, LDL apheresis, and other investigational therapies may play a role in certain subsets of FH, which are challenging to treat. Together these novel treatments have notably improved the prognosis of FH, especially that of the heterozygous patients. Despite these achievements, a majority of children fail to attain targeted lipid goals owing to persistent shortcomings in diagnosis, monitoring, and treatment. This review aims to highlight the screening, diagnosis, goals of therapy, and management options in patients with FH. PMID:24987256

    1993-01-01

    The Nigerian Family Health services project teamed up with the Johns Hopkins University's Population Communication Services to produce songs called "Choices" and "Wait for Me." The songs, which were about sexual responsibility, were performed by popular music stars King Sunny Ade and Onyeka Onwenu and appeared under King Sonny Ade's long playing albums in 1989. Teaching sexual responsibility through song was suggested in focus group discussions. Findings indicated that young people were responsive to messages about sexual responsibility, postponing sex or saying "no," male sexual responsibility, and children by informed choice and not chance among married couples. An impact assessment of the songs was conducted in February, 1991. Survey findings revealed that 64% of urban and 22% of rural respondents recalled having heard the songs and seen the videos. 48% of urban youth discussed the songs with friends, and 27% discussed the songs with sexual partners. 90% of respondents reported agreement with the message that couples should have only the number of children that they can care for, and that couples should practice family planning. The target population that was affected most by the songs was aged less than 35 years. The strategy of using songs to teach youth responsible parenting appears to be a reliable strategy for mass education and mobilization. There is mass support from among members of the National Council for Women's Societies, the Planned Parenthood Federation of Nigeria, and Coca Cola Corporation, as well as the public at large.

    A unique kindred with premature cardiovascular disease, tubo-eruptive xanthomas, and type III hyperlipoproteinemia (HLP) associated with familial apolipoprotein (apo) E deficiency was examined. Homozygotes (n = 4) had marked increases in cholesterol-rich very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL), which could be effectively lowered with diet and medication (niacin, clofibrate). Homozygotes had only trace amounts of plasma apoE, and accumulations of apoB-48 and apoA-IV in VLDL, IDL, and low density lipoproteins. Radioiodinated VLDL apoB and apoE kinetic studies revealed that the homozygous proband had markedly retarded fractional catabolism of VLDL apoB-100, apoB-48 and plasma apoE, as well as an extremely low apoE synthesis rate as compared to normals. Obligate heterozygotes (n = 10) generally had normal plasma lipids and mean plasma apoE concentrations that were 42% of normal. The data indicate that homozygous familial apoE deficiency is a cause of type III HLP, is associated with markedly decreased apoE production, and that apoE is essential for the normal catabolism of triglyceride-rich lipoprotein constituents.

    2015-01-01

    Familial exudative vitreoretinopathy (FEVR) is a hereditary disease associated with visual loss, particularly in the pediatric group. Mutations in the NDP, FZD4, LRP5, and TSPAN12 genes have been shown to contribute to FEVR. FEVR has been reported to have X-linked recessive, autosomal dominant, and autosomal recessive inheritances. However, both the genotypic and phenotypic features are variable. Novel mutations contributing to the disease have been reported. The earliest and the most prominent finding of the disease is avascularity in the peripheral retina. As the disease progresses, retinal neovascularization, subretinal exudation, partial and total retinal detachment may occur, which may be associated with certain mutations. With early diagnosis and prompt management visual loss can be prevented with laser photocoagulation and anti-VEGF injections. In case of retinal detachment, pars plana vitrectomy alone or combined with scleral buckling should be considered. Identifying asymptomatic family members with various degrees of insidious findings is of certain importance. Wide-field imaging with fluorescein angiography is crucial in the management of this disease. The differential diagnosis includes other pediatric vitreoretinopathies such as Norrie disease, retinopathy of prematurity, and Coats’ disease. PMID:27800225

    During the NASA-Mir program of the 1990s and due to the challenges inherent in the International Space Station training schedule and operations tempo, it was clear that a special focus on supporting families was a key to overall mission success for the ISS crewmembers pre-, in- and post-flight. To that end, in January 2001 the first Family Services Coordinator was hired by the Behavioral Health and Performance group at NASA JSC and matrixed from Medical Operations into the Astronaut Office's organization. The initial roles and responsibilities were driven by critical needs, including facilitating family communication during training deployments, providing mission-specific and other relevant trainings for spouses, serving as liaison for families with NASA organizations such as Medical Operations, NASA management and the Astronaut Office, and providing assistance to ensure success of an Astronaut Spouses Group. The role of the Family Support Office (FSO) has modified as the ISS Program matured and the needs of families changed. The FSO is currently an integral part of the Astronaut Office's ISS Operations Branch. It still serves the critical function of providing information to families, as well as being the primary contact for US and international partner families with resources at JSC. Since crews launch and return on Russian vehicles, the FSO has the added responsibility for coordinating with Flight Crew Operations, the families, and their guests for Soyuz launches, landings, and Direct Return to Houston post-flight. This presentation will provide a summary of the family support services provided for astronauts, and how they have changed with the Program and families the FSO serves. Considerations for future FSO services will be discussed briefly as NASA proposes one year missions and beyond ISS missions. Learning Objective: 1) Obtain an understanding of the reasons a Family Support Office was important for NASA. 2) Become familiar with the services provided for

  20. Familial adenomatous polyposis.

    Half, Elizabeth; Bercovich, Dani; Rozen, Paul

    2009-01-01

    Familial adenomatous polyposis (FAP) is characterized by the development of many tens to thousands of adenomas in the rectum and colon during the second decade of life. FAP has an incidence at birth of about 1/8,300, it manifests equally in both sexes, and accounts for less than 1% of colorectal cancer (CRC) cases. In the European Union, prevalence has been estimated at 1/11,300-37,600. Most patients are asymptomatic for years until the adenomas are large and numerous, and cause rectal bleeding or even anemia, or cancer develops. Generally, cancers start to develop a decade after the appearance of the polyps. Nonspecific symptoms may include constipation or diarrhea, abdominal pain, palpable abdominal masses and weight loss. FAP may present with some extraintestinal manifestations such as osteomas, dental abnormalities (unerupted teeth, congenital absence of one or more teeth, supernumerary teeth, dentigerous cysts and odontomas), congenital hypertrophy of the retinal pigment epithelium (CHRPE), desmoid tumors, and extracolonic cancers (thyroid, liver, bile ducts and central nervous system). A less aggressive variant of FAP, attenuated FAP (AFAP), is characterized by fewer colorectal adenomatous polyps (usually 10 to 100), later age of adenoma appearance and a lower cancer risk. Some lesions (skull and mandible osteomas, dental abnormalities, and fibromas on the scalp, shoulders, arms and back) are indicative of the Gardner variant of FAP. Classic FAP is inherited in an autosomal dominant manner and results from a germline mutation in the adenomatous polyposis (APC) gene. Most patients (~70%) have a family history of colorectal polyps and cancer. In a subset of individuals, a MUTYH mutation causes a recessively inherited polyposis condition, MUTYH-associated polyposis (MAP), which is characterized by a slightly increased risk of developing CRC and polyps/adenomas in both the upper and lower gastrointestinal tract. Diagnosis is based on a suggestive family history

The practice of pediatrics is unique among medical specialties in many ways, among which is the nearly certain presence of a parent when health care services are provided for the patient. Regardless of whether parents or other family members are physically present, their influence is pervasive. Families are the most central and enduring influence in children's lives. Parents are also central in pediatric care. The health and well-being of children are inextricably linked to their parents' physical, emotional and social health, social circumstances, and child-rearing practices. The rising incidence of behavior problems among children attests to some families' inability to cope with the increasing stresses they are experiencing and their need for assistance. When a family's distress finds its voice in a child's symptoms, pediatricians are often parents' first source for help. There is enormous diversity among families-diversity in the composition of families, in their ethnic and racial heritage, in their religious and spiritual orientation, in how they communicate, in the time they spend together, in their commitment to individual family members, in their connections to their community, in their experiences, and in their ability to adapt to stress. Within families, individuals are different from one another as well. Pediatricians are especially sensitive to differences among children-in their temperaments and personalities, in their innate and learned abilities, and in how they view themselves and respond to the world around them.

    Familial spontaneous pneumothorax is one of the phenotypes of Birt-Hogg-Dubé syndrome (BHDS), an autosomal dominant condition associated with folliculin (FLCN). We investigated clinical and genetic data of an Indian family having two patients suffering from spontaneous pneumothorax in the absence of skin lesions or renal tumors. HRCT scan of patient's lung revealed paracardiac cysts, and DNA sequencing of all 14 exons of FLCN from patients showed the presence of heterozygous "C allele" deletion in the poly-cytosine (poly-C) tract of exon 11 leading to truncated folliculin. This mutation was also observed in four asymptomatic members of the family. Our results confirmed the presence of deletion mutation in poly-C tract of FLCN in members of BHDS family. This is the first report of genetic insight in a BHDS family from India but in-depth studies with a larger sample set are necessary to understand mechanism of familial pneumothorax.

    Vietnamese immigrants in the United States face acculturation challenges involving the individual, family, and community. Experts suggest that immigrant family members acculturate at different rates resulting in an acculturation gap, which negatively influences family adjustment. In this study we examined the degree and patterns of acculturation differences between 104 first generation immigrant Vietnamese adolescents and their parents, and whether acculturation gap affected family relationships. Operationalizing the “gap” as both absolute value of differences in acculturation and interactions of parent and adolescent acculturation levels, we examined the impact of such gaps in Vietnamese and American language, identity, and behavioral acculturation on family relationships. Results revealed that family cohesion and satisfaction were predicted by gaps in Vietnamese identity acculturation, but not by gaps in other acculturation domains. PMID:20161537

    2016-01-01

    Family health history about cancer is an important prevention and health promotion tool. Yet few studies have identified family context factors that promote such discussions. We explored relations among family context (cohesion, flexibility, and openness), self-efficacy, and cancer communication (gathering family history, sharing cancer risk information, and frequency) in a diverse group of women enrolled in a randomized control trial. Baseline survey data for 472 women were analyzed. The women's average age was 34 years, 59% identified as Black, 31% had graduated high school, and 75% reported a family history of any cancer. Results showed that greater family cohesion and flexibility were related to higher communication frequency and sharing cancer information. Women who reported greater self-efficacy were more likely to have gathered family history, shared cancer risk information, and communicated more frequently with relatives. Openness was not associated with communication but was related to greater family cohesion and flexibility. Adjusting for demographic variables, self-efficacy, and family cohesion significantly predicted communication frequency. Women with higher self-efficacy were also more likely to have gathered family health history about cancer and shared cancer risk information. Future research may benefit from considering family organization and self-efficacy when developing psychosocial theories that in turn inform cancer prevention interventions.

Of the families evaluated we found 26 patients with ovarian cancer and twenty two with different cancers in other sites. In ovarian cancer the familial aspect, despite its relatively low frequency, is one of the few factors for identifying "high risk" patients, thus allowing effective secondary prevention.

    The diagnosis of cancer is a family experience that changes the lives of all its members, bringing an immense amount of stress and many challenging situations. The daily routine, common activities and distribution of duties all have to change. Family members follow the phases of the disease, very often suffering comparable or greater distress than the patient. They use various coping methods which aim at helping both the sick relative and themselves. These methods, together with emotional responses, change over time according to the phase of the disease. Cancer puts the family at risk since it imposes an alternation in the relations among family members. It affects the couple's relationship, their sex life, and it can also be a cause of major trauma among their children and adolescents. The diagnosis of cancer brings also individual risks for the family members in terms of psychological and physical health impairment. Family caregivers often feel overloaded with the additional obligations and roles they have to pick up. They find it increasingly burdening to care full-time for the household and provide emotional support for the patient. The family's problems and the way family members regard the disease may be also a result of the family system they are in. This article describes the nature of caregiving to a patient with cancer and the biggest concerns for the family. PMID:26327863

    Abstract Objective To explore patients’ perceptions of primary care (PC) in the early development of academic family health teams (aFHTs)—interprofessional PC teams delivering care where family medicine and other health professional learners are trained—focusing on patients’ perceptions of access and patients’ satisfaction with services. Design Self-administered survey. Setting Six aFHTs in Ontario. Participants Adult patients attending appointments and administrators at each of the aFHTs. Main outcome measures Answers to questions about access from the Primary Care Assessment Tool Adult Expanded Version, the Primary Care Assessment Survey, and research team questions. Results The response rate was 47.3% (1026 of 2167). The mean (SD) Primary Care Assessment Tool first-contact accessibility score was 2.28 (0.36) out of 4, with 96.5% of patients rating access less than 3, which was the minimum expected level of care. Two-thirds (66.6%) indicated someone from their aFHTs would definitely or probably see them the same day if they were sick, 56.8% could definitely or probably get advice quickly by telephone, and 14.5% indicated it was definitely or probably difficult to be seen by their primary health care provider (HCP). Additionally, 46.9% indicated they would like to get medical advice by e-mail. For a routine or follow-up visit, 73.4% would be willing to see another aFHT physician if their regular provider were unavailable, while only 48.3% would see a nonphysician HCP. If sick, 88.2% would see another aFHT physician and 55.2% would see a nonphysician HCP. Most (75.3%) were satisfied with access to their regular HCP. Conclusion Although patients are generally satisfied with care, there is room for improvement in access. Strategies are needed to enhance access to care, including addressing appropriate roles and scopes of practice for nonphysician HCPs. The accessibility challenges for aFHTs will likely affect new family physicians and other HCPs training in

    Using data from the 1972-1973 Consumer Expenditure Survey, this article examines the effect of variations in family size on such measures of family economic well-being as levels and patterns of spending, earnings and employment, public assistance and the quantity and quality of housing. In general, although overall income rises somewhat with family size, an increase in the number of children appears to reduce the family's standard of living, especially in young families with small children. Current consumption increases as the number of children increases: families with 4 or more children in which the household head is under the age of 35 and has had more than 12 years of education tend to spend 40% more than childless couples of similar age and educational level. Despite the increased spending, per capita consumption falls for all age and education categories. Larger families devote more of their income to necessities and less to luxuries. Among young couples in which the household head has had 9 to 12 years of education, the proportion of income used to buy food rises from 15% if there are no children present to 25% if there are 4 or more. The proportion of food expenditures devoted to meals eaten out also falls steadily as the number of children rises. Although husband's earnings rise with increase in family size, there is a pronounced decline in wife's earnings, particularly in young families that have children under the age of 4. Overall, as the number of children grows, families spend a larger share of their income on current consumption, and per capita income declines. The % of families receiving welfare or food stamps tends to go up as the number of children increases, particularly among younger couples with less education. When the quantity and quality of housing are examined, the average number of rooms in the family dwelling is found to increase with family size.

  12. Why family planning matters.

    Family planning is one of the principle tools of human development. Ensuring that all babies are wanted and planned reduces health care and social costs. Human numbers will increase to 11 billion by the end of this century, and human activities are the leading cause of environmental change that threaten our health and happiness. Therefore, the provision of highly effective contraceptive methods represents an important priority of primary medical care. Since women and men with complicated medical problems remain interested in sex, medical and surgical specialists need to understand how contraception and pregnancy will interact with the underlying condition. This paper discusses the interaction between population growth and the environment, and reviews modern methods of contraception.

    The diverse biological effects of somatostatin (SST) are mediated through a family of G protein coupled receptors of which 5 members have been recently identified by molecular cloning. This review focuses on the molecular biology, pharmacology, expression, and function of these receptors with particular emphasis on the human (h) homologs. hSSTRs are encoded by a family of 5 genes which map to separate chromosomes and which, with one exception, are intronless. SSTR2 gives rise to spliced variants, SSTR2A and 2B. hSSTR1-4 display weak selectivity for SST-14 binding whereas hSSTR5 is SST-28 selective. Based on structural similarity and reactivity for octapeptide and hexapeptide SST analogs, hSSTR2,3, and 5 belong to a similar SSTR subclass. hSSTR1 and 4 react poorly with these analogs and belong to a separate subclass. All 5 hSSTRs are functionally coupled to inhibition of adenylyl cyclase via pertussis toxin sensitive GTP binding proteins. Some of the subtypes are also coupled to tyrosine phosphatase (SSTR1,2), Ca2+ channels (SSTR2), Na+/H+ exchanger (SSTR1), PLA-2 (SSTR4), and MAP kinase (SSTR4). mRNA for SSTR1-5 is widely expressed in brain and peripheral organs and displays an overlapping but characteristic pattern that is subtype-selective, and tissue- and species-specific. Pituitary and islet tumors express several SSTR genes suggesting that multiple SSTR subtypes are coexpressed in the same cell. Structure-function studies indicate that the core residues in SST-14 ligand Phe6-Phe11 dock within a ligand binding pocket located in TMDs 3-7 which is lined by hydrophobic and charged amino acid residues.

    Abstract Familial Mediterranean fever (FMF) is an autoinflammatory disease caused by MEditerranean FeVer gene (MEFV) mutations. In Japan, patients with FMF have been previously reported, including a mild or incomplete form. Several factors are presumed to contribute to the variable penetrance and to the phenotypic variability of FMF. We conducted the current study to investigate the correlation of variable clinical presentations and MEFV genotypic distributions in Japanese FMF patients. We analyzed demographic, clinical, and genetic data for 311 FMF patients enrolled in the study. Clinically, we classified FMF into 2 phenotypes: 1) the “typical” form of FMF, and 2) the “atypical” form of FMF according to the Tel Hashomer criteria. Patients with the typical FMF phenotype had a higher frequency of febrile episodes, a shorter duration of febrile attacks, more frequent thoracic pain, abdominal pain, a family history of FMF, and MEFV exon 10 mutations. Conversely, patients with the atypical FMF phenotype had a lower frequency of fever episodes and more frequent arthritis in atypical distribution, myalgia, and MEFV exon 3 mutations. Multivariate analysis showed that the variable associated with typical FMF presentation was the presence of MEFV exon 10 mutations. Typical FMF phenotype frequencies were decreased in patients carrying 2 or a single low-penetrance mutations compared with those carrying 2 or a single high-penetrance mutations (M694I), with an opposite trend for the atypical FMF phenotype. In addition, patients having more than 2 MEFV mutations had a younger disease onset and a higher prevalence of thoracic pain than those carrying a single or no mutations. Thus, MEFV exon 10 mutations are associated with the more typical FMF phenotype. In contrast, more than half of the Japanese FMF patients without MEFV exon 10 mutations presented with an atypical FMF phenotype, indicating that Japanese FMF patients tend to be divided into 2 phenotypes by a variation

  15. Familial hemiplegic migraine.

    PubMed

    Hansen, Jakob Møller

    2010-09-01

    Familial hemiplegic migraine (FHM) is a rare, dominantly inherited subtype of migraine with aura, where hemiplegia occurs during the aura phase. Mutation screening of families with FHM has revealed a range of different mutations. The mutated FHM genes code for ion transport proteins. Animal and cellular studies have associated the mutated FHM genes with disturbed ion homeostasis, altered cellular excitability and altered neurotransmitter release. Abnormal cortical excitability due to dysfunctional ion-channels might facilitate cortical spreading depression (CSD) and thereby migraine aura and migraine headache. Genotyped FHM patients offer us the chance to study the interplay between genotype and phenotype and may be regarded as a genetic migraine model. FHM studies might open for a better understanding of the molecular migraine pathology, and potentially help to unravel the pathogenesis of the more common migraine forms. We have therefore studied genotyped FHM patients to understand the effect of genotype on the response to migraine provoking substances. We show here that two known migraine triggers failed to induce more migraine aura or migraine headache in FHM-patients than in healthy controls, thus indicating that the FHM genotype does not confer hypersensitivity to these migraine triggers. This has implications for our understanding of the headache mechanisms and raises the question whether FHM share neurobiological background with the common types of migraine. The aims of the present thesis were to test the hypothesis that FHM mutations might be associated with hypersensitivity to known migraine triggers and, thereby, share pathophysiological pathways with the common types of migraine, but our results disprove this hypothesis. Thus, FHM seems very different from MO and MA, both genetically and pathophysiologically. The fact that FHM genes regulate ion homeostasis cannot be extrapolated to the common types of migraine.

    Chiari malformations (Types I-IV) are abnormalities of the posterior fossa that affect the cerebellum, brainstem, and the spinal cord with prevalence rates of 0.1%-0.5%. Case reports of familial aggregation of Chiari malformation, twin studies, cosegregation of Chiari malformation with known genetic conditions, and recent gene and genome-wide association studies provide strong evidence of the genetic underpinnings of familial Chiari malformation. The authors report on a series of 3 family pairs with Chiari malformation Type I: 2 mother-daughter pairs and 1 father-daughter pair. The specific genetic causes of familial Chiari malformation have yet to be fully elucidated. The authors review the literature and discuss several candidate genes. Recent advances in the understanding of the genetic influences and pathogenesis of familial Chiari malformation are expected to improve management of affected patients and monitoring of at-risk family members.

    2011-01-01

    In the United States, several states have made policy decisions regarding whether and how to use familial searching of the Combined DNA Index System (CODIS) database in criminal investigations. Familial searching pushes DNA typing beyond merely identifying individuals to detecting genetic relatedness, an application previously reserved for missing persons identifications and custody battles. The intentional search of CODIS for partial matches to an item of evidence offers law enforcement agencies a powerful tool for developing investigative leads, apprehending criminals, revitalizing cold cases and exonerating wrongfully convicted individuals. As familial searching involves a range of logistical, social, ethical and legal considerations, states are now grappling with policy options for implementing familial searching to balance crime fighting with its potential impact on society. When developing policies for familial searching, legislators should take into account the impact of familial searching on select populations and the need to minimize personal intrusion on relatives of individuals in the DNA database. This review describes the approaches used to narrow a suspect pool from a partial match search of CODIS and summarizes the economic, ethical, logistical and political challenges of implementing familial searching. We examine particular US state policies and the policy options adopted to address these issues. The aim of this review is to provide objective background information on the controversial approach of familial searching to inform policy decisions in this area. Herein we highlight key policy options and recommendations regarding effective utilization of familial searching that minimize harm to and afford maximum protection of US citizens. PMID:22040348

    Family Medicine in Singapore has its roots in a generalist ethos and found its origin as a counter culture movement to the increasing sub-specialisation of medicine which resulted in a complex healthcare system where that patients are often cared for by multiple specialists potentially resulting in fragmentation of care. The aim of the discipline of Family Medicine was to train and develop more generalist physicians so as to promote holistic care.

    2013-01-01

    Narrative medicine has become a prominent method of developing more empathetic relationships between medical clinicians and patients, on the basis of a deeper understanding of the patient experience. Beyond its usefulness during clinical encounters, patient storytelling can inform processes and procedures in Advisory Councils, Committee Meetings, and Family as Faculty settings, leading to improved quality and safety in health care. Armed with a better understanding of the patient experience, clinicians and administrators can make decisions, hopefully in collaboration with patients, that will enrich the patient experience and increase satisfaction among patients, families, and staff. Patient and family storytelling is a key component of the collaboration that is ideal when an organization seeks to deliver patient- and family-centered care. Providing patients and families with training will make the narratives they share more powerful. Health care organizations will find that purposeful storytelling can be an invaluable aspect of a patient- and family-centered culture. Well-delivered storytelling will support quality- and safety-improvement efforts and contribute to improved patient satisfaction. This article provides instruction for teaching patients and families how to tell stories with purpose and offers advice about how to support patients, families, and clinicians participating in this effort.

  2. Family psychology and family law--a family court judge's perspective: comment on the special issue.

    PubMed

    Kreeger, Judith L

    2003-06-01

    This comment presents the responses of an experienced family court judge to the eight articles published in this special issue. The value of these scholarly articles to family court judges is enormous. Judges have little, if any, formal training in family dynamics and child development, yet are called upon to make rulings in complex cases that have life-long ramifications for all family members. The changing demographics and current realities of traditional and nontraditional family structures in our society as well as the increasing divorce rates have widened the gap between legal precedence and current social science research. It is essential that the material covered in this issue can be accessible to family law personnel in language that they can understand and learn from.

  3. Multigene families in African swine fever virus: family 505.

    PubMed Central

    Rodriguez, J M; Yañez, R J; Pan, R; Rodriguez, J F; Salas, M L; Viñuela, E

    1994-01-01

    Sequencing of restriction fragment EcoRI A-SalI C of African swine fever virus has revealed the existence of a multigene family, designated family 505 because of the average number of amino acids in the proteins, composed of seven homologous and tandemly arranged genes. All the genes of family 505 are expressed during infection. Primer extension analysis showed that transcription is initiated a short distance (3 to 62 nucleotides) from the start codon of the corresponding open reading frame. The proteins of family 505 showed similarity to those of family 360 from African swine fever virus. In particular, a striking conservation of three regions at the amino terminus of the polypeptides was observed. Images PMID:8139051

    Abstract Objective To explore patients’ perceptions of primary care (PC) in the early development of academic family health teams (aFHTs)—interprofessional PC teams delivering care where family medicine and other health professional learners are trained—focusing on the 4 core domains of PC. Design Self-administered survey using the Primary Care Assessment Tool Adult Expanded Version (PCAT), which addresses 4 core domains of PC (first contact, continuity, comprehensiveness, and coordination). The PCAT uses a 4-point Likert scale (from definitely not to definitely) to capture patients’ responses about the occurrence of components of care. Setting Six aFHTs in Ontario. Participants Adult patients attending appointments and administrators at each of the aFHTs. Main outcome measures Mean PCAT domain scores, with a score of 3 chosen as the minimum expected level of care. Multivariate log binomial regression models were used to estimate the adjusted relative risks of PCAT score levels as functions of patient- and clinic-level characteristics. Results The response rate was 47.3% (1026 of 2167). The mean age of respondents was 49.6 years, and most respondents were female (71.6%). The overall PC score (2.92) was just below the minimum expected care level. Scores for first contact (2.28 [accessibility]), coordination of information systems (2.67), and comprehensiveness of care (2.83 [service available] and 2.36 [service provided]) were below the minimum. Findings suggest some patient groups might not be optimally served by aFHTs, particularly recent immigrants. Characteristics of aFHTs, including a large number of physicians, were not associated with high performance on PC domains. Distributed practices across multiple sites were negatively associated with high performance for some domains. The presence of electronic medical records was not associated with improved performance on coordination of information systems. Conclusion Patients of these aFHTs rated several

  5. The fibrillar collagen family.

    PubMed

    Exposito, Jean-Yves; Valcourt, Ulrich; Cluzel, Caroline; Lethias, Claire

    2010-01-01

    Collagens, or more precisely collagen-based extracellular matrices, are often considered as a metazoan hallmark. Among the collagens, fibrillar collagens are present from sponges to humans, and are involved in the formation of the well-known striated fibrils. In this review we discuss the different steps in the evolution of this protein family, from the formation of an ancestral fibrillar collagen gene to the formation of different clades. Genomic data from the choanoflagellate (sister group of Metazoa) Monosiga brevicollis, and from diploblast animals, have suggested that the formation of an ancestral alpha chain occurred before the metazoan radiation. Phylogenetic studies have suggested an early emergence of the three clades that were first described in mammals. Hence the duplication events leading to the formation of the A, B and C clades occurred before the eumetazoan radiation. Another important event has been the two rounds of "whole genome duplication" leading to the amplification of fibrillar collagen gene numbers, and the importance of this diversification in developmental processes. We will also discuss some other aspects of fibrillar collagen evolution such as the development of the molecular mechanisms involved in the formation of procollagen molecules and of striated fibrils.

  2. The biology of family psychotherapy.

    PubMed

    Kramer, D A

    2001-07-01

    This article has presented a view of biologic psychiatry consistent with that described by Bowlby, discussed hypotheses concerning the biologic purpose of the primate brain and the human brain, and challenged standard beliefs about the identity of the patient entity in a true biologically based psychiatry. Ideas developed by Whitaker, Malone, and their colleagues almost 50 years ago are consistent with a modern biologic basis of family psychotherapy. The treatment of an anorexic family was used to illustrate possible mechanisms of psychotherapeutic treatment requiring the presence of the whole family. The role of the psychiatrist who treats a family is to understand the biologic or medical importance of treating the family as a whole, communicate this to the family, continually work toward that level of participation, suggest relevant topics for discussion, and catalyze interactions within the family. Psychotherapy with families as a whole is effective because of the power of kin selection and inclusive fitness, biologic processes not usually considered in the practice of medicine or psychiatry.

  8. Family transitions and juvenile delinquency.

    PubMed

    Schroeder, Ryan D; Osgood, Aurea K; Oghia, Michael J

    2010-01-01

    There is a large body of research that shows children from non-intact homes show higher rates of juvenile delinquency than children from intact homes, partially due to weaker parental control and supervision in non-intact homes. What has not been adequately addressed in the research is the influence of changes in family structure among individual adolescents over time on delinquent offending. Using the first and third waves of the National Youth Study, we assess the effect of family structure changes on changes in delinquent offending between waves through the intermediate process of changes in family time and parental attachment. Although prior research has documented adolescents in broken homes are more delinquent than youth in intact homes, the process of family dissolution is not associated with concurrent increases in offending. In contrast, family formation through marriage or cohabitation is associated with simultaneous increases in offending. Changes in family time and parental attachment account for a portion of the family formation effect on delinquency, and prior parental attachment and juvenile offending significantly condition the effect of family formation on offending.

    PubMed Central

    Hennen, B K

    1993-01-01

    Fifty years ago family practice in Canada had no academic presence. Stimulated by a number of general practitioners and with the support of the Canadian Medical Association, the College of General Practitioners of Canada (CGPC) was founded in 1954. In 1962, conferences on education for general practice attended by the Association of Canadian Medical Colleges and the CGPC led to pilot postgraduate residencies in family practice supported by Department of National Health and Welfare. The first certification examination was held in 1969 and, by 1974, all Canadian medical schools had a family medicine residency program. Today departments of family medicine contribute substantially to undergraduate education in all 16 schools. In Canada, the medical profession, governments and the medical schools have demonstrated the importance they place on appropriate education for family physicians. PMID:8477381

    PubMed

    Niederhofer, H; Hackenberg, B; Lanzendörfer, K

    2004-04-01

    A lack of perseverance, poor attention, and poorly modulated behaviour are important criteria of Attention Deficit Hyperactive Disorder (ADHD). Instructions often have to be repeated, sometimes even by different family members before a child with ADHD attends and complies. We hypothesised that a child with ADHD might cause less disagreement in families with almost no conflicts. Responses to the Mannheim Parents Interview and teacher's form of the Conners scale completed by families of 15 boys (ages 6 to 12 years), diagnosed with ADHD were compared with those of a matched, healthy control group of 15 boys. Parents completed a form assessing the family's cooperation and child-rearing practices. Having few family conflicts, i.e., almost no Verbal Disagreement may reduce Physical Punishment and Anger and Disregard and augment the Openness to another's needs and, for that reason, have protective effects on children's behaviour modulation.

  7. On family secrets and -K.

    PubMed

    Orgad, Yariv

    2014-08-01

    In this paper I present a novel interpretation of family secrets. Leaning on Bion's concept of -K, the constitution of secrecy is interpreted in terms of family dynamics that actively prevent knowledge formation and mental growth. Family secrets are interpreted as a destructive process that attacks the family's truth-generating-space - the shared semiotic space within which meanings are constituted through family relationships. The paper explores the microstructure interpersonal process of -K through the analysis of Mike Leigh's movie, Secrets and Lies. Two scenes in the movie are used to demonstrate how -K is worked out in the form of a specific intersubjective semiotic endeavor that unconsciously blocks the process of meaning-making.

Leaning on Bion's concept of -K, the constitution of secrecy is interpreted in terms of family dynamics that actively prevent knowledge formation and mental growth. Family secrets are interpreted as a destructive process that attacks the family's truth-generating-space - the shared semiotic space within which meanings are constituted through family relationships. The paper explores the microstructure interpersonal process of -K through the analysis of Mike Leigh's movie, Secrets and Lies. Two scenes in the movie are used to demonstrate how -K is worked out in the form of a specific intersubjective semiotic endeavor that unconsciously blocks the process of meaning-making.

    A group of cross-hybridizing DNA segments contained within the restriction fragments RK', RL, RJ, and RD' of African swine fever virus DNA were mapped and sequenced. Analysis of these sequences revealed the presence of a family of homologous open reading frames in regions close to the DNA ends. The whole family is composed of six open reading frames with an average length of 360 coding triplets (multigene family 360), four of which are located in the left part of the genome and two of which are in the right terminal EcoRI fragment. In close proximity to the right terminal inverted repeat, we found an additional small open reading frame which was homologous to the 5'-terminal portion of the other open reading frames, suggesting that most of that open reading frame has been deleted. These repeated sequences account for the previously described inverted internal repetitions (J.M. Sogo, J.M. Almendral, A. Talavera, and E. Viñuela, Virology 133:271-275, 1984). Most of the genes of multigene family 360 are transcribed in African swine fever virus-infected cells. A comparison of the predicted protein sequences of family 360 indicated that several residues are conserved, suggesting that an overall structure is maintained for every member of the family. The transcription direction of each open reading frame, as well as the evolutionary relationships among the genes, suggests that the family originated by gene duplication and translocation of sequences between the DNA ends.

  10. Connectedness versus separateness: applicability of family therapy to Japanese families.

    This article, a product of the two authors' multicultural experiences, contrasts British and Japanese families in order to examine the applicability of the Western model of family therapy to Japanese families and therapists. Areas where the Western model is incompatible are identified, and modifications to fit the Japanese indigenous model are suggested. The most significant difference in value systems between the two cultures is the Japanese preference for connectedness. The Japanese person is seen as a part of the embedded interconnectedness of relationships, whereas British norms prioritize separateness and clear boundaries in relationships, individuality, and autonomy. This value orientation is manifested in the Japanese language, hierarchical nature of the family structure, the family life cycle, and the implicit communication style. Systemic thinking, which deals with the pattern of relationships, is valid for all families regardless of cultural differences. But therapists should note that the preferred direction of change for Japanese families in therapy, is toward a process of integration--how a person can be effectively integrated into the given system--rather than a process of differentiation. An authoritative therapist style, the use of individual sessions, silence, and other nonverbal techniques are relevant to bringing about the desired change toward better integration of the individual with his or her networks.

    Caring for dying patients and their families presents unique opportunities and challenges for the family physician. The family FIRO model provides a simple way of assessing families and providing appropriate, individualized care. This article outlines the model, discusses the care of dying patients and their families from the FIRO perspective, and provides a guideline for the family physician. A framework is suggested for teaching residents to support families. PMID:21228989

  12. Familial Sinistrals Avoid Exact Numbers

    We report data from an internet questionnaire of sixty number trivia. Participants were asked for the number of cups in their house, the number of cities they know and 58 other quantities. We compare the answers of familial sinistrals – individuals who are left-handed themselves or have a left-handed close blood-relative – with those of pure familial dextrals – right-handed individuals who reported only having right-handed close blood-relatives. We show that familial sinistrals use rounder numbers than pure familial dextrals in the survey responses. Round numbers in the decimal system are those that are multiples of powers of 10 or of half or a quarter of a power of 10. Roundness is a gradient concept, e.g. 100 is rounder than 50 or 200. We show that very round number like 100 and 1000 are used with 25% greater likelihood by familial sinistrals than by pure familial dextrals, while pure familial dextrals are more likely to use less round numbers such as 25, 60, and 200. We then use Sigurd’s (1988, Language in Society) index of the roundness of a number and report that familial sinistrals’ responses are significantly rounder on average than those of pure familial dextrals. To explain the difference, we propose that the cognitive effort of using exact numbers is greater for the familial sinistral group because their language and number systems tend to be more distributed over both hemispheres of the brain. Our data support the view that exact and approximate quantities are processed by two separate cognitive systems. Specifically, our behavioral data corroborates the view that the evolutionarily older, approximate number system is present in both hemispheres of the brain, while the exact number system tends to be localized in only one hemisphere.

    Familiar hypercholesterolemia (FH) is genetic disease characterized with extremely high levels of cholesterol leading to cholesterol deposition in skin and tissues and premature atherosclerosis due to defective LDL receptors. In homozygous individuals (HoFH) premature cardiovascular (CV) events and aortic stenosis could develop at very early ages due to the exposure of the vessels including aorta to high lipid levels since birth. Patients with HoFH do not respond to conventional antilipid agents including statins due to defective LDL receptors. Therefore,LDL apheresis is still the only choice of treatment in HoFH. However, in order to prevent both the development of CV events and aortic stenosis, regular apheresis should be initiated before the age of 10 years. With the knowledge of the 21.2% consanguineous marriages in Turkey, it could be suggested that the prevalence of FH is high in our country. However, the frequency of HoFH in Turkey is not known and there is limited data on prognosis in long term studies. This limited data denotes an extremely high mortality and morbidity in patients with HoFH. The main problem in these patients is late diagnosis leading to a delayed treatment. However, early diagnosis is the key factor for the prevention of premature atherosclerosis and for ensuring long-term survival in HoFH. Moreover, FH is a genetic disease that could be easily diagnosed with a detailed family history, physical examination, and assessment of lipid levels. In order to commence early diagnosis and early treatment, awareness of the physicians should be increased. Particularly raising the awareness among primary care physicians regarding high cholesterol levels in children and adolescents would be a substantial step. Public should realize that FH is a common disease with high mortality, and that the harms of high cholesterol begin in childhood. In order to achieve all these goals, National policy for the diagnosis and management of AH is warranted. PMID

    An emergent grounded theory was used to examine Professionalizing Familial Care, the processes by which registered nurses enact professional care work within the familial care domain. A sample of registered nurses (n = 32) were interviewed by telephone at multiple time points over a 6- to 12-month period. The findings revealed that the professionalization of care work was often reinforced by societal, familial, and self-expectations. Setting Limits and Making Connections were the dialectical overarching processes shaping the professionalizing of care while 6 interdependent substrategies emerged: assessing, advising, advocating, collaborating, coordinating, and consulting. These findings will help inform refinement of policies and practices for nurses who provide care for an older relative.

    We report eight patients with familial tropical spastic paraparesis belonging to four families. The diagnosis was reached by clinical, radiological and electrophysiological studies. Human lymphotropic virus type I infection was confirmed by ELISA, immunofluorescence essays. Western blot and polymerase chain reaction in DNA of peripheral blood mononuclear cells, using primers for tax and 5'ltr genes. In all these families there was a vertical transmission of the disease from the first to the second generation. All patients improved their spastic gait after prednisone treatment. Among patients of the second generation, all had dacrysialoadenitis, three had leukemia like lymphocytes in the blood smear, two had mycosis fungoides and one had hepatic cirrhosis.

  20. Fragile families and child wellbeing.

    Jane Waldfogel, Terry-Ann Craigie, and Jeanne Brooks-Gunn review recent studies that use data from the Fragile Families and Child Wellbeing Study (FFCWS) to examine why children who grow up in single-mother and cohabiting families fare worse than children born into married-couple households. They also present findings from their own new research. Analysts have investigated five key pathways through which family structure might influence child well-being: parental resources, parental mental health, parental relationship quality, parenting quality, and father involvement. It is also important to consider the role of the selection of different types of men and women into different family types, as well as family stability. But analysts remain uncertain how each of these elements shapes children's outcomes. In addition to providing an overview of findings from other studies using FFCWS, Waldfogel, Craigie, and Brooks-Gunn report their own estimates of the effect of a consistently defined set of family structure and stability categories on cognitive, behavioral, and health outcomes of children in the FFCWS study at age five. The authors find that the links between fragile families and child outcomes are not uniform. Family instability, for example, seems to matter more than family structure for cognitive and health outcomes, whereas growing up with a single mother (whether that family structure is stable or unstable over time) seems to matter more than instability for behavior problems. Overall, their results are consistent with other research findings that children raised by stable single or cohabiting parents are at less risk than those raised by unstable single or cohabiting parents. The authors conclude by pointing to three types of policy reforms that could improve outcomes for children. The first is to reduce the share of children growing up in fragile families (for example, through reducing the rate of unwed births or promoting family stability among unwed
