    Regulated polyadenylation is a broadly conserved mechanism that controls key events during oogenesis. Pivotal to that mechanism is GLD-2, a catalytic subunit of cytoplasmic poly(A) polymerase (PAP). Caenorhabditis elegans GLD-2 forms an active PAP with multiple RNA-binding partners to regulate diverse aspects of germline and early embryonic development. One GLD-2 partner, RNP-8, was previously shown to influence oocyte fate specification. Here we use a genomic approach to identify transcripts selectively associated with both GLD-2 and RNP-8. Among the 335 GLD-2/RNP-8 potential targets, most were annotated as germline mRNAs and many as maternal mRNAs. These targets include gld-2 and rnp-8 themselves, suggesting autoregulation. Removal of either GLD-2 or RNP-8 resulted in shortened poly(A) tails and lowered abundance of four target mRNAs (oma-2, egg-1, pup-2, and tra-2); GLD-2 depletion also lowered the abundance of most GLD-2/RNP-8 putative target mRNAs when assayed on microarrays. Therefore, GLD-2/RNP-8 appears to polyadenylate and stabilize its target mRNAs. We also provide evidence that rnp-8 influences oocyte development; rnp-8 null mutants have more germ cell corpses and fewer oocytes than normal. Furthermore, RNP-8 appears to work synergistically with another GLD-2binding partner, GLD-3, to ensure normal oogenesis. We propose that the GLD-2/RNP-8 enzyme is a broad-spectrum regulator of the oogenesis program that acts within an RNA regulatory network to specify and produce fully functional oocytes.

    Cytoplasmic polyadenylation is a post-transcriptional mechanism regulating mRNA stability and translation. The human p53 3'-untranslated region (3'-UTR) contains two regions similar to cytoplasmic polyadenylation elements (CPEs) just upstream of the poly(A) hexanucleotide. Evaluation of the p53 CPE......-like elements was performed by luciferase reporter assays, qPCR, and poly(A) assays. Herein, we report the down regulation of a luciferase reporter fused to the p53 3'-UTR, when human CPE-binding protein 1 (hCPEB1) is overexpressed. This inhibition is partially rescued when hCPEB1fused to hGLD-2 [a human...... cytoplasmic poly(A) polymerase] is overexpressed instead. The stability of a luciferase mRNA containing the p53 3'-UTR downstream, is decreased when hCPEB1 is overexpressed as seen by qPCR. Expression of hGLD-2 restores the mRNA stability. This is due to elongation of the poly(A) tail as seen by a PCR...

    Full Text Available The liver-specific microRNA miR-122, which has essential roles in liver development and metabolism, is a key proviral factor for hepatitis C virus (HCV. Despite its crucial role in the liver and HCV life cycle, little is known about the molecular mechanism of miR-122 expression regulation by HCV infection. Here, we show that the HCV core protein downregulates the abundance of miR-122 by promoting its destabilization via the inhibition of GLD-2, a non-canonical cytoplasmic poly(A polymerase. The decrease in miR-122 expression resulted in the dysregulation of the known functions of miR-122, including its proviral activity for HCV. By high-throughput sequencing of small RNAs from human liver biopsies, we found that the 22-nucleotide (nt prototype miR-122 is modified at its 3' end by 3'-terminal non-templated and templated nucleotide additions. Remarkably, the proportion of miR-122 isomers bearing a single nucleotide tail of any ribonucleotide decreased in liver specimens from patients with HCV. We found that these single-nucleotide-tailed miR-122 isomers display increased miRNA activity and stability over the 22-nt prototype miR-122 and that the 3'-terminal extension is catalyzed by the unique terminal nucleotidyl transferase activity of GLD-2, which is capable of adding any single ribonucleotide without preference of adenylate to the miR-122 3' end. The HCV core protein specifically inhibited GLD-2, and its interaction with GLD-2 in the cytoplasm was found to be responsible for miR-122 downregulation. Collectively, our results provide new insights into the regulatory role of the HCV core protein in controlling viral RNA abundance and miR-122 functions through miR-122 stability modulation.

    Full Text Available Parkinson's disease (PD is a progressive neurodegenerative disorder affecting approximately 1-2% of the general population over age 60. It is characterized by a rather selective loss of dopaminergic neurons in the substantia nigra and the presence of α-synuclein-enriched Lewy body inclusions. Mutations in the Parkin gene (PARK2 are the major cause of autosomal recessive early-onset parkinsonism. The Parkin protein is an E3 ubiquitin ligase with various cellular functions, including the induction of mitophagy upon mitochondrial depolarizaton, but the full repertoire of Parkin-binding proteins remains poorly defined. Here we employed tandem affinity purification interaction screens with subsequent mass spectrometry to profile binding partners of Parkin. Using this approach for two different cell types (HEK293T and SH-SY5Y neuronal cells, we identified a total of 203 candidate Parkin-binding proteins. For the candidate proteins and the proteins known to cause heritable forms of parkinsonism, protein-protein interaction data were derived from public databases, and the associated biological processes and pathways were analyzed and compared. Functional similarity between the candidates and the proteins involved in monogenic parkinsonism was investigated, and additional confirmatory evidence was obtained using published genetic interaction data from Drosophila melanogaster. Based on the results of the different analyses, a prioritization score was assigned to each candidate Parkin-binding protein. Two of the top ranking candidates were tested by co-immunoprecipitation, and interaction to Parkin was confirmed for one of them. New candidates for involvement in cell death processes, protein folding, the fission/fusion machinery, and the mitophagy pathway were identified, which provide a resource for further elucidating Parkin function.

    Insulin-like growth factor binding protein-3 (IGFBP-3) is known to inhibit cell proliferation and induce apoptosis in IGF-dependent and IGF-independent manners, but the mechanism underlying IGF-independent effects is not yet clear. In a yeast two-hybrid assay, IGFBP-3 was used as the bait to screen a human fetal liver cDNA library for it interactors that may potentially mediate IGFBP-3-regulated functions. N-Acetylgalactosaminyltransferase 14 (GalNAc-T14), a member of the GalNAc-Tases family, was identified as a novel IGFBP-3 binding partner. This interaction involved the ricin-type beta-trefoil domain of GalNAc-T14. The interaction between IGFBP-3 and GalNAc-T14 was reconfirmed in vitro and in vivo, using GST pull-down, co-immunoprecipitation and mammalian two-hybrid assays. Our findings may provide new clues for further study on the mechanism behind the IGF-independent effects of IGFBP-3 promoting apoptosis. The role of GalNAc-T14 as an intracellular mediator of the effects of IGFBP-3 need to be verified in future studies

  9. RSK2 and its binding partners in cell proliferation, transformation and cancer development.

    RSK2 is a serine/threonine kinase and a member of the p90 ribosomal S6 kinase (p90 RSK ; RSKs) family, which regulates cell proliferation and transformation induced by tumor promoters such as epithelial growth factor (EGF), 12-O-tetradecanoylphorbol-13-acetate (TPA), and ultraviolet (UV) radiation. RSKs respond to many growth factors, hormones, neurotransmitters and environmental stresses. In signaling cascades, RSK2 is regulated under the control of extracellular signal-regulated kinase 1 (ERK1) and 2 (ERK2) activities and is positioned upstream of transcription and epigenetic factors involved in cell proliferation, cell transformation and cancer development, as well as some kinases that modulate cell cycle progression. Over the last decade, our research group has studied the etiological roles of RSK2 in human cancer development, discovering that RSK2 plays a key role in cell proliferation, transformation and cancer development in humans. Based on our research, we concluded that RSK2 plays a key role as an onco-kinase by combinational protein-protein interaction with different binding partners depending on the cellular context. In this review, we discuss the function of the RSK2 signaling axis by interactions with binding partners in cancer development.

    Asymmetric cell division requires the orientation of mitotic spindles along the cell-polarity axis. In Drosophila neuroblasts, this involves the interaction of the proteins Inscuteable (Insc) and Partner of inscuteable (Pins). We report here that a human Pins-related protein, called LGN, is instead essential for the assembly and organization of the mitotic spindle. LGN is cytoplasmic in interphase cells, but associates with the spindle poles during mitosis. Ectopic expression of LGN disrupts spindle-pole organization and chromosome segregation. Silencing of LGN expression by RNA interference also disrupts spindle-pole organization and prevents normal chromosome segregation. We found that LGN binds the nuclear mitotic apparatus protein NuMA, which tethers spindles at the poles, and that this interaction is required for the LGN phenotype. Anti-LGN antibodies and the LGN-binding domain of NuMA both trigger microtubule aster formation in mitotic Xenopus egg extracts, and the NuMA-binding domain of LGN blocks aster assembly in egg extracts treated with taxol. Thus, we have identified a mammalian Pins homologue as a key regulator of spindle organization during mitosis.

  11. Izumo1 and Juno: the evolutionary origins and coevolution of essential sperm-egg binding partners.

    Reproductive proteins are among the most rapidly evolving classes of proteins. For a subset of these, rapid evolution is driven by positive Darwinian selection despite vital, well-conserved, reproductive functions. Izumo1 is the only essential sperm-egg fusion protein currently known on mammalian sperm, and its egg receptor (Juno; formerly Folr4) was recently discovered. Male knockout mice for Izumo1 and female knockout mice for Juno are both healthy but sterile. Here, both sperm-egg binding proteins are shown to be evolving under positive selection. Within mammals, coevolution of Izumo1 and Juno is also uncovered, suggesting that similar forces have shaped the evolutionary histories of these binding partners within Mammalia. Additionally, genomic analyses reveal an ancient origin for the Izumo gene family, initially reported as conserved exclusively in mammals. Newly identified Izumo1 orthologues could serve reproductive functions in birds, fish and reptiles. Surprisingly, these same analyses support Juno's presence in mammals alone, suggesting a recent mammalian-specific duplication and neofunctionalization of the ancestral folate receptor. Despite the indispensability of their reproductive interaction, and their apparent coevolution within Mammalia, this binding pair arose through strikingly different evolutionary forces.

    Small and large scale proteomic technologies are providing a wealth of potential interactions between proteins bearing phospho-recognition modules and their substrates. Resulting interaction maps reveal such a dense network of interactions that the functional dissection and understanding of these networks often require to break specific interactions while keeping the rest intact. Here, we developed a computational strategy, called STRIP, to predict the precise interaction site involved in an interaction with a phospho-recognition module. The method was validated by a two-hybrid screen carried out using the ForkHead Associated (FHA)1 domain of Rad53, a key protein of Saccharomyces cerevisiae DNA checkpoint, as a bait. In this screen we detected 11 partners, including Cdc7 and Cdc45, essential components of the DNA replication machinery. FHA domains are phospho-threonine binding modules and the threonines involved in both interactions could be predicted using the STRIP strategy. The threonines T484 and T189 in Cdc7 and Cdc45, respectively, were mutated and loss of binding could be monitored experimentally with the full-length proteins. The method was further tested for the analysis of 63 known Rad53 binding partners and provided several key insights regarding the threonines likely involved in these interactions. The STRIP method relies on a combination of conservation, phosphorylation likelihood, and binding specificity criteria and can be accessed via a web interface at http://biodev.extra.cea.fr/strip/.

    Methylation of DNA CpG sites is a major mechanism of epigenetic gene silencing and plays important roles in cell division, development and carcinogenesis. One of its regulators is the 64-residue C-terminal Transcriptional Repressor Domain (the TRD) of MBD1, which recruits several repressor proteins such as MCAF1, HDAC3 and MPG that are essential for the gene silencing. Using NMR spectroscopy, we have characterized the solution structure of the C-terminus of MBD1 (MBD1-c, residues D507 to Q605), which included the TRD (A529 to P592). Surprisingly, the MBD1-c is intrinsically disordered. Despite its lack of a tertiary folding, MBD1-c could still bind to different partner proteins in a selective manner. MPG and MCAF1Δ8 showed binding to both the N-terminal and C-terminal residues of MBD1-c but HDAC3 preferably bound to the C-terminal region. This study reveals how MBD1-c discriminates different binding partners, and thus, expands our understanding of the mechanisms of gene regulation by MBD1.

    In this study, the binding behaviour of methylmercury (MeHg(+)) towards proteins is investigated. Free sulfhydryl groups in cysteine residues are known to be the most likely binding partners, due to the high affinity of mercury to sulphur. However, detailed knowledge about discrete binding sites in living organisms has been so far scarce. A metallomics approach using different methods like size-exclusion chromatography (SEC) and liquid chromatography (LC) coupled to inductively coupled plasma-mass spectrometry (ICP-MS) as well as complementary mass spectrometric techniques (electrospray ionisation-tandem mass spectrometry, ESI-MS/MS) are combined to sequence and identify possible target proteins or peptides after enzymatic digestion. Potential targets for MeHg(+) in tuna fish muscle tissue are investigated using the certified reference material CRM464 as a model tissue. Different extraction procedures appropriate for the extraction of proteins are evaluated for their efficiency using isotope dilution analysis for the determination of total Hg in the extracts. Due to the high chemical stability of the mercury-sulphur bond, the bioconjugate can be quantitatively extracted with a combination of tris(hydroxymethyl)aminomethane (TRIS) and sodium dodecyl sulphate (SDS). Using different separation techniques such as SEC and SDS-polyacrylamide gel electrophoresis (SDS-PAGE) it can be shown that major binding occurs to a high-molecular weight protein (M(w) > 200 kDa). A potential target protein, skeletal muscle myosin heavy chain, could be identified after tryptic digestion and capillary LC-ESI-MS/MS.

  17. The chromatin remodelling factor BRG1 is a novel binding partner of the tumor suppressor p16INK4a

    2009-01-01

    Full Text Available Abstract Background CDKN2A/p16INK4a is frequently altered in human cancers and it is the most important melanoma susceptibility gene identified to date. p16INK4a inhibits pRb phosphorylation and induces cell cycle arrest, which is considered its main tumour suppressor function. Nevertheless, additional activities may contribute to the tumour suppressor role of p16INK4a and could help explain its specific association with melanoma predisposition. To identify such functions we conducted a yeast-two-hybrid screen for novel p16INK4a binding partners. Results We now report that p16INK4a interacts with the chromatin remodelling factor BRG1. We investigated the cooperative roles of p16INK4a and BRG1 using a panel of cell lines and a melanoma cell model with inducible p16INK4a expression and BRG1 silencing. We found evidence that BRG1 is not required for p16INK4a-induced cell cycle inhibition and propose that the p16INK4a-BRG1 complex regulates BRG1 chromatin remodelling activity. Importantly, we found frequent loss of BRG1 expression in primary and metastatic melanomas, implicating this novel p16INK4a binding partner as an important tumour suppressor in melanoma. Conclusion This data adds to the increasing evidence implicating the SWI/SNF chromatin remodelling complex in tumour development and the association of p16INK4a with chromatin remodelling highlights potentially new functions that may be important in melanoma predisposition and chemoresistance.

    Highlights: → A yeast two-hybrid screen revealed testin bound to the calcium-sensing receptor. → The second zinc finger of LIM domain 1 of testin is critical for interaction. → Testin bound to a region of the receptor tail important for cell signalling. → Testin and receptor interaction was confirmed in mammalian (HEK293) cells. → Overexpression of testin enhanced receptor-mediated Rho signalling in HEK293 cells. -- Abstract: The calcium-sensing receptor (CaR) plays an integral role in calcium homeostasis and the regulation of other cellular functions including cell proliferation and cytoskeletal organisation. The multifunctional nature of the CaR is manifested through ligand-dependent stimulation of different signalling pathways that are also regulated by partner binding proteins. Following a yeast two-hybrid library screen using the intracellular tail of the CaR as bait, we identified several novel binding partners including the focal adhesion protein, testin. Testin has not previously been shown to interact with cell surface receptors. The sites of interaction between the CaR and testin were mapped to the membrane proximal region of the receptor tail and the second zinc-finger of LIM domain 1 of testin, the integrity of which was found to be critical for the CaR-testin interaction. The CaR-testin association was confirmed in HEK293 cells by coimmunoprecipitation and confocal microscopy studies. Ectopic expression of testin in HEK293 cells stably expressing the CaR enhanced CaR-stimulated Rho activity but had no effect on CaR-stimulated ERK signalling. These results suggest an interplay between the CaR and testin in the regulation of CaR-mediated Rho signalling with possible effects on the cytoskeleton.

    A modular strategy for protein crystallization using split green fluorescent protein (GFP) as a crystallization partner is demonstrated. Insertion of a hairpin containing GFP β-strands 10 and 11 into a surface loop of a target protein provides two chain crossings between the target and the reconstituted GFP compared with the single connection afforded by terminal GFP fusions. This strategy was tested by inserting this hairpin into a loop of another fluorescent protein, sfCherry. The crystal structure of the sfCherry-GFP(10-11) hairpin in complex with GFP(1-9) was determined at a resolution of 2.6 Å. Analysis of the complex shows that the reconstituted GFP is attached to the target protein (sfCherry) in a structurally ordered way. This work opens the way to rapidly creating crystallization variants by reconstituting a target protein bearing the GFP(10-11) hairpin with a variety of GFP(1-9) mutants engineered for favorable crystallization.

A significant correlation was found between TIMP-1 and CD63, and the TIMP-1 and CD63 proteins were co-expressed at the cellular level and located in close molecular proximity, suggesting that TIMP-1 and CD63 could be co-players...... of this study was to assess CD63 expression in astrocytomas focusing on the prognostic potential of CD63 alone and in combination with TIMP-1. Methods: CD63 expression was investigated immunohistochemically in a cohort of 111 astrocytomas and correlated to tumor grade and overall survival by semi-quantitative...... scoring. CD63 expression in tumor-associated microglia/macrophages was examined by double-immunofluorescence with ionized calcium-binding adapter molecule 1 (Iba1). The association between CD63 and TIMP-1 was investigated using previously obtained TIMP-1 data from our astrocytoma cohort. Cellular co-expression...

  1. In-frame cDNA library combined with protein complementation assay identifies ARL11-binding partners.

    Sangkyou Lee

    Full Text Available The cDNA expression libraries that produce correct proteins are essential in facilitating the identification of protein-protein interactions. The 5'-untranslated regions (UTRs that are present in the majority of mammalian and non-mammalian genes are predicted to alter the expression of correct proteins from cDNA libraries. We developed a novel cDNA expression library from which 5'-UTRs were removed using a mixture of polymerase chain reaction primers that complement the Kozak sequences we refer to as an "in-frame cDNA library." We used this library with the protein complementation assay to identify two novel binding partners for ras-related ADP-ribosylation factor-like 11 (ARL11, cellular retinoic acid binding protein 2 (CRABP2, and phosphoglycerate mutase 1 (PGAM1. Thus, the in-frame cDNA library without 5'-UTRs we describe here increases the chance of correctly identifying protein interactions and will have wide applications in both mammalian and non-mammalian detection systems.

    Highlights: • p32 binds to Mcl-1. • p32 affects apoptosis. • p32 and Mcl-1 regulate mitochondrial Ca{sup 2+}. - Abstract: Mcl-1 is a major anti-apoptotic Bcl-2 family protein. It is well known that Mcl-1 can interact with certain pro-apoptotic Bcl-2 family proteins in normal cells to neutralize their pro-apoptotic functions, thus prevent apoptosis. In addition, it was recently found that Mcl-1 can also inhibit mitochondrial calcium uptake. The detailed mechanism, however, is still not clear. Based on Yeast Two-Hybrid screening and co-immunoprecipitation, we identified a mitochondrial protein p32 (C1qbp) as a novel binding partner of Mcl-1. We found that p32 had a number of interesting properties: (1) p32 can positively regulate UV-induced apoptosis in HeLa cells. (2) Over-expressing p32 could significantly promote mitochondrial calcium uptake, while silencing p32 by siRNA suppressed it. (3) In p32 knockdown cells, Ruthenium Red treatment (an inhibitor of mitochondrial calcium uniporter) showed no further suppressive effect on mitochondrial calcium uptake. In addition, in Ruthenium Red treated cells, Mcl-1 also failed to suppress mitochondrial calcium uptake. Taken together, our findings suggest that p32 is part of the putative mitochondrial uniporter that facilitates mitochondrial calcium uptake. By binding to p32, Mcl-1 can interfere with the uniporter function, thus inhibit the mitochondrial Ca{sup 2+} uploading. This may provide a novel mechanism to explain the anti-apoptotic function of Mcl-1.

    Muscle LIM protein (MLP) is a striated muscle-specific factor that enhances myogenic differentiation and is critical to maintaining the structural integrity of the contractile apparatus. The ability of MLP to regulate myogenesis is particularly interesting since it exhibits multiple subcellular localizations, being found in both nuclear and cytoplasmic compartments. Despite extensive biochemical analyses on MLP, the mechanism(s) by which it influences the myogenic program remains largely undefined. To further examine the role of MLP as a positive myogenic regulator, a yeast two-hybrid screen was employed to identify cytoplasmic-associated MLP binding partners. From this screen, the cytoskeletal protein betaI-spectrin was isolated. Protein interaction assays demonstrate that MLP and betaI-spectrin associate with one another in vivo as well as when tested under several in vitro binding conditions. betaI-spectrin binds specifically to MLP but not to the MLP related proteins CRP1 and CRP2 or to other LIM domain containing proteins. The MLP:beta-spectrin interaction is mediated by the second LIM motif of MLP and by repeat 7 of beta-spectrin. Confocal microscopy studies also reveal that MLP co-localizes with beta-spectrin at the sarcolemma overlying the Z- and M-lines of myofibrils in both cardiac and skeletal muscle tissue. Given that beta-spectrin is a known costamere protein, we propose that sarcolemma-associated MLP also serves as a key costamere protein, stabilizing the association of the contractile apparatus with the sarcolemma by linking the beta-spectrin network to the alpha-actinin crosslinked actin filaments of the myofibril.

  4. A single β-octyl glucoside molecule induces HIV-1 Nef dimer formation in the absence of partner protein binding.

    Full Text Available The HIV-1 Nef accessory protein is essential for viral pathogenicity and AIDS progression. Nef forms complexes with multiple host cell factors to facilitate viral replication and promote immune escape of HIV-infected cells. Previous X-ray crystal structures demonstrate that Nef forms homodimers, the orientation of which are influenced by host cell binding partners. In cell-based fluorescence complementation assays, Nef forms homodimers at the plasma membrane. However, recombinant Nef proteins often exist as monomers in solution, suggesting that membrane interaction may also trigger monomer to dimer transitions. In this study, we show that monomeric Nef core proteins can be induced to form dimers in the presence of low concentrations of the non-ionic surfactant, β-octyl glucoside (βOG. X-ray crystallography revealed that a single βOG molecule is present in the Nef dimer, with the 8-carbon acyl chain of the ligand binding to a hydrophobic pocket formed by the dimer interface. This Nef-βOG dimer interface involves helix αB, as observed in previous dimer structures, as well as a helix formed by N-terminal residues 54-66. Nef dimer formation is stabilized in solution by the addition of βOG, providing biochemical validation for the crystal structure. These observations together suggest that the interaction with host cell lipid mediators or other hydrophobic ligands may play a role in Nef dimerization, which has been previously linked to multiple Nef functions including host cell protein kinase activation, CD4 downregulation, and enhancement of HIV-1 replication.

    PspA, -B and -C regulate the bacterial phage shock protein stress response by controlling the PspF transcription factor. Here, we have developed complementary approaches to study the behaviour of these proteins at their endogenous levels in Yersinia enterocolitica. First, we observed GFP-tagged versions with an approach that resolves individual protein complexes in live cells. This revealed that PspA, -B and -C share common behaviours, including a striking contrast before and after induction. In uninduced cells, PspA, -B and -C were highly mobile and widely distributed. However, induction reduced mobility and the proteins became more organized. Combining mCherry- and GFP-tagged proteins also revealed that PspA colocalizes with PspB and PspC into large stationary foci, often located close to the pole of induced cells. In addition, co-immunoprecipitation assays provided the first direct evidence supporting the model that PspA switches binding partners from PspF to PspBC upon induction. Together, these data suggest that PspA, -B and -C do not stably interact and are highly mobile before induction, perhaps sampling the status of the membrane and each other. However, an inducing signal promotes PspABC complex formation and their relocation to discrete parts of the membrane, which might then be important for mitigating envelope stress. © 2013 Blackwell Publishing Ltd.

    Caseinolytic peptidase P (ClpP), a double-ring peptidase with 14 subunits, collaborates with ATPases associated with diverse activities (AAA+) partners to execute ATP-dependent protein degradation. Although many ClpP enzymes self-assemble into catalytically active homo-tetradecamers able to cleave small peptides, the Mycobacterium tuberculosis enzyme consists of discrete ClpP1 and ClpP2 heptamers that require a AAA+ partner and protein-substrate delivery or a peptide agonist to stabilize assembly of the active tetradecamer. Here, we show that cyclic acyldepsipeptides (ADEPs) and agonist peptides synergistically activate ClpP1P2 by mimicking AAA+ partners and substrates, respectively, and determine the structure of the activated complex. Our studies establish the basis of heteromeric ClpP1P2 assembly and function, reveal tight coupling between the conformations of each ring, show that ADEPs bind only to one ring but appear to open the axial pores of both rings, provide a foundation for rational drug development, and suggest strategies for studying the roles of individual ClpP1 and ClpP2 rings in Clp-family proteolysis.

    2011-01-01

    In the field of biotechnology, fusing recombinant proteins to highly soluble partners is a common practice for overcoming aggregation in Escherichia coli. E. coli maltose-binding protein (MBP) has been recognized as one of the most effective solubilizing agents, having frequently been observed to improve the yield, enhance the solubility, and promote the proper folding of its fusion partners. The use of a dual hexahistidine-maltose-binding protein affinity tag (His(6)-MBP) has the additional advantage of allowing the fusion protein to be purified by immobilized metal affinity chromatography (IMAC) instead of or in addition to amylose affinity chromatography. This chapter describes a generic method for the overproduction of combinatorially tagged His(6)-MBP fusion proteins in E. coli, with particular emphasis on the use of recombinational cloning to construct expression vectors. In addition, simple methods for evaluating the solubility of the fusion protein and the passenger protein after it is cleaved from the dual His(6)-MBP tag are presented.

    Insolubility of recombinant proteins in Escherichia coli is a major impediment to their production for structural and functional studies. One way to circumvent this problem is to fuse an aggregation-prone protein to a highly soluble partner. E. coli maltose-binding protein (MBP) has emerged as one of the most effective solubilizing agents. In this chapter, we describe how to construct combinatorially-tagged His(6)MBP fusion proteins by recombinational cloning and how to evaluate their yield and solubility. We also describe a procedure to determine how efficiently a His(6)MBP fusion protein is cleaved by tobacco etch virus (TEV) protease in E. coli and a method to assess the solubility of the target protein after it has been separated from His(6)MBP.

    Translationally controlled tumor protein (TCTP) is a highly conserved housekeeping protein present in eukaryotic organisms. It is involved in regulating many fundamental processes and plays a critical role in tumor reversion and tumorigenesis. Increasing evidence suggests that TCTP plays a role in the regulation of cell fate determination and is a promising therapeutic target for cancer. To decipher the exact mechanisms by which TCTP functions and how all these functions are integrated, we analyzed the interactome of TCTP in HeLa cells by coimmunoprecipitation (IP) and mass spectrometry (MS). A total of 98 proteins were identified. We confirmed the in vitro and in vivo association of TCTP with six of the identified binding proteins using reciprocal IP and bimolecular fluorescence complementation (BiFC) analysis, respectively. Moreover, TCTP interacted with Y-box-binding protein 1 (YBX1), and their interaction was localized to the N-terminal region of TCTP and the 1-129 amino acid (aa) residues of YBX1. The YBX1 protein plays an important role in cell proliferation, RNA splicing, DNA repair, drug resistance, and stress response to extracellular signals. These data suggest that the interaction of TCTP with YBX1 might cooperate or coordinate their functions in the control of diverse regulatory pathways in cancer cells. Taken together, our results not only reveal a large number of TCTP-associated proteins that possess pleiotropic functions, but also provide novel insights into the molecular mechanisms of TCTP in tumorigenesis.

    Full Text Available Maintenance of functional mitochondria is vital for optimal cell performance and survival. This is accomplished by distinct mechanisms, of which preservation of mitochondrial protein homeostasis fulfills a pivotal role. In plants, inner membrane-embedded i-AAA protease, FTSH4, contributes to the mitochondrial proteome surveillance. Owing to the limited knowledge of FTSH4’s in vivo substrates, very little is known about the pathways and mechanisms directly controlled by this protease. Here, we applied substrate trapping coupled with mass spectrometry-based peptide identification in order to extend the list of FTSH4’s physiological substrates and interaction partners. Our analyses revealed, among several putative targets of FTSH4, novel (mitochondrial pyruvate carrier 4 (MPC4 and Pam18-2 and known (Tim17-2 substrates of this protease. Furthermore, we demonstrate that FTSH4 degrades oxidatively damaged proteins in mitochondria. Our report provides new insights into the function of FTSH4 in the maintenance of plant mitochondrial proteome.

    Full Text Available Long non-coding RNA (lncRNA, a novel and effective modulator in carcinogenesis, has become a study hotspot in recent years. The imprinted oncofetal lncRNA H19 is one of the first identified imprinted lncRNAs with a high expression level in embryogenesis but is barely detectable in most tissues after birth. Aberrant alterations of H19 expression have been demonstrated in various tumors, including gastric cancer (GC, implicating a crucial role of H19 in cancer progression. As one of the top malignancies in the world, GC has already become a serious concern to public health with poor prognosis. The regulatory roles of H19 in gastric carcinogenesis have been explored by various research groups, which leads to the development of GC therapy. This review comprehensively summarizes the current knowledge of H19 in tumorigenesis, especially in GC pathogenesis, with emphasis on the underneath molecular mechanisms depicted from its functional partners. Furthermore, the accumulated knowledge of H19 will provide better understanding on targeted therapy of GC.

  12. Control of flowering and cell fate by LIF2, an RNA binding partner of the polycomb complex component LHP1.

    David Latrasse

    Full Text Available Polycomb Repressive Complexes (PRC modulate the epigenetic status of key cell fate and developmental regulators in eukaryotes. The chromo domain protein like heterochromatin protein1 (LHP1 is a subunit of a plant PRC1-like complex in Arabidopsis thaliana and recognizes histone H3 lysine 27 trimethylation, a silencing epigenetic mark deposited by the PRC2 complex. We have identified and studied an LHP1-Interacting Factor2 (LIF2. LIF2 protein has RNA recognition motifs and belongs to the large hnRNP protein family, which is involved in RNA processing. LIF2 interacts in vivo, in the cell nucleus, with the LHP1 chromo shadow domain. Expression of LIF2 was detected predominantly in vascular and meristematic tissues. Loss-of-function of LIF2 modifies flowering time, floral developmental homeostasis and gynoecium growth determination. lif2 ovaries have indeterminate growth and produce ectopic inflorescences with severely affected flowers showing proliferation of ectopic stigmatic papillae and ovules in short-day conditions. To look at how LIF2 acts relative to LHP1, we conducted transcriptome analyses in lif2 and lhp1 and identified a common set of deregulated genes, which showed significant enrichment in stress-response genes. By comparing expression of LHP1 targets in lif2, lhp1 and lif2 lhp1 mutants we showed that LIF2 can either antagonize or act with LHP1. Interestingly, repression of the FLC floral transcriptional regulator in lif2 mutant is accompanied by an increase in H3K27 trimethylation at the locus, without any change in LHP1 binding, suggesting that LHP1 is targeted independently from LIF2 and that LHP1 binding does not strictly correlate with gene expression. LIF2, involved in cell identity and cell fate decision, may modulate the activity of LHP1 at specific loci, during specific developmental windows or in response to environmental cues that control cell fate determination. These results highlight a novel link between plant RNA

  13. Identification of a tankyrase-binding motif shared by IRAP, TAB182, and human TRF1 but not mouse TRF1. NuMA contains this RXXPDG motif and is a novel tankyrase partner.

    Tankyrase-1 and -2 are closely related poly(ADP-ribose) polymerases that use an ankyrin-repeat domain to bind diverse proteins, including TRF (telomere-repeat binding factor)-1, IRAP (insulin-responsive aminopeptidase), and TAB182 (182-kDa tankyrase-binding protein). TRF1 binding allows tankyrase to regulate telomere dynamics in human cells, whereas IRAP binding presumably allows tankyrase to regulate the targeting of IRAP. The mechanism by which tankyrase binds to diverse proteins has not been investigated. Herein we describe a novel RXXPDG motif shared by IRAP, TAB182, and human TRF1 that mediates their binding to tankyrases. Interestingly, mouse TRF1 lacks this motif and thus does not bind either tankyrase-1 or -2. Using the ankyrin domain of tankyrase as a bait in a yeast two-hybrid screen, we also found the RXXPDG motif in six candidate tankyrase partners, including the nuclear/mitotic apparatus protein (NuMA). We verified NuMA as an RXXPDG-mediated partner of tankyrase and suggest that this interaction contributes to the known colocalization of tankyrase and NuMA at mitotic spindle poles.

    DOCK7 (dedicator of cytokinesis 7) is a guanidine nucleotide exchange factor (GEF) for Rac1 GTPase that is involved in neuronal polarity and axon generation as well in Schwann cell differentiation and myelination. Recently, we identified DOCK7 as the binding partner of unconventional myosin VI (MVI) in neuronal-lineage PC12 cells and postulated that this interaction could be important in vivo [Majewski et al. (2012) Biochem Cell Biol., 90:565-574]. Herein, we found that MVI-DOCK7 interaction takes also place in other cell lines and demonstrated that MVI cargo domain via its RRL motif binds to DOCK7 C-terminal M2 and DHR2 domains. In MVI knockdown cells, lower Rac1 activity and a decrease of DOCK7 phosphorylation on Tyr1118 were observed, indicating that MVI could contribute to DOCK7 activity. MVI and DOCK7 co-localization was maintained during NGF-stimulated PC12 cell differentiation and observed also in the outgrowths. Also, during differentiation an increase in phosphorylation of DOCK7 as well as of its downstream effector JNK kinase was detected. Interestingly, overexpression of GFP-tagged MVI cargo domain (GFP-GT) impaired protrusion formation indicating that full length protein is important for this process. Moreover, a transient increase in Rac activity observed at 5min of NGF-stimulated differentiation of PC12 cells (overexpressing either GFP or GFP-MVI) was not detected in cells overexpressing the cargo domain. These data indicate that MVI-DOCK7 interaction could have functional implications in the protrusion outgrowth, and full length MVI seems to be important for delivery and maintenance of DOCK7 along the protrusions, and exerting its GEF activity.

    SAP-1 is a 113 amino acid long single-chain protein which belongs to the type 2 cystatin gene family. In our previous study, we have purified SAP-1 from human seminal plasma and observed its cross-class inhibitory property. At this time, we report the interaction of SAP-1 with diverse proteases and its binding partners by CD-spectroscopic and molecular docking methods. The circular dichroism (CD) spectroscopic studies demonstrate that the conformation of SAP-1 is changed after its complexation with proteases, and the alterations in protein secondary structure are quantitatively calculated with increase of α-helices and reduction of β-strand content. To get insight into the interactions between SAP-1 and proteases, we make an effort to model the three-dimensional structure of SAP-1 by molecular modeling and verify its stability and viability through molecular dynamics simulations and finally complexed with different proteases using ClusPro 2.0 Server. A high degree of shape complementarity is examined within the complexes, stabilized by a number of hydrogen bonds (HBs) and hydrophobic interactions. Using HB analyses in different protein complexes, we have identified a series of key residues that may be involved in the interactions between SAP-1 and proteases. These findings will assist to understand the mechanism of inhibition of SAP-1 for different proteases and provide intimation for further research.

    2012-06-01

    Full Text Available Abstract Background HIV-1 Nef protein contributes to pathogenesis via multiple functions that include enhancement of viral replication and infectivity, alteration of intracellular trafficking, and modulation of cellular signaling pathways. Nef stimulates formation of tunneling nanotubes and virological synapses, and is transferred to bystander cells via these intercellular contacts and secreted microvesicles. Nef associates with and activates Pak2, a kinase that regulates T-cell signaling and actin cytoskeleton dynamics, but how Nef promotes nanotube formation is unknown. Results To identify Nef binding partners involved in Pak2-association dependent Nef functions, we employed tandem mass spectrometry analysis of Nef immunocomplexes from Jurkat cells expressing wild-type Nef or Nef mutants defective for the ability to associate with Pak2 (F85L, F89H, H191F and A72P, A75P in NL4-3. We report that wild-type, but not mutant Nef, was associated with 5 components of the exocyst complex (EXOC1, EXOC2, EXOC3, EXOC4, and EXOC6, an octameric complex that tethers vesicles at the plasma membrane, regulates polarized exocytosis, and recruits membranes and proteins required for nanotube formation. Additionally, Pak2 kinase was associated exclusively with wild-type Nef. Association of EXOC1, EXOC2, EXOC3, and EXOC4 with wild-type, but not mutant Nef, was verified by co-immunoprecipitation assays in Jurkat cells. Furthermore, shRNA-mediated depletion of EXOC2 in Jurkat cells abrogated Nef-mediated enhancement of nanotube formation. Using bioinformatic tools, we visualized protein interaction networks that reveal functional linkages between Nef, the exocyst complex, and the cellular endocytic and exocytic trafficking machinery. Conclusions Exocyst complex proteins are likely a key effector of Nef-mediated enhancement of nanotube formation, and possibly microvesicle secretion. Linkages revealed between Nef and the exocyst complex suggest a new paradigm of

    The tumor-suppressor RUNX3 has a critical role in a lineage determination, cell cycle arrest and apoptosis. Lozenge (Lz), a Drosophila homolog of mammalian RUNX family members, has integral roles in these processes and specifically in eye cell fate determination. To elucidate the genetic modifiers of Lz/RUNX3, we performed a large-scale functional screen in a fly mutant library. The screen revealed genetic interactions between the Lz, Rac and Hippo pathways. Analysis of interactions among these genes revealed that the defective phenotype resulting from activation of Yki, an end point effector of the Hippo pathway, was suppressed by Lz and enhanced by Rac-Trio. Molecular biological analysis using mammalian homologs reveled that LATS1/2-mediated YAP phosphorylation-facilitated dissociation of the YAP-TEAD4 complex and association of the YAP-RUNX3 complex. When cells were stimulated to proliferate, activated RAC-TRIO signaling inhibited LATS1/2-mediated YAP phosphorylation; consequently, YAP dissociated from RUNX3 and associated with TEAD, thereby replacing the YAP-RUNX3 complex with YAP-TEAD. RUNX3 contributed to both association and dissociation of YAP-TEAD complex, most likely through the formation of the YAP-TEAD-RUNX3 ternary complex. Ectopic expression of RUNX3 in MKN28 gastric cancer cells reduced tumorigenicity, and the tumor-suppressive activity of RUNX3 was associated with its ability to interact with YAP. These results identify a novel regulatory mechanism, mediated by the Hippo and RAC-TRIO pathways, that changes the binding partner of YAP.

  18. The Sec1/Munc18 protein Vps45 regulates cellular levels of its SNARE binding partners Tlg2 and Snc2 in Saccharomyces cerevisiae.

    Directory of Open Access Journals (Sweden)

    Scott G Shanks

    Full Text Available Intracellular membrane trafficking pathways must be tightly regulated to ensure proper functioning of all eukaryotic cells. Central to membrane trafficking is the formation of specific SNARE (soluble N-ethylmeleimide-sensitive factor attachment protein receptor complexes between proteins on opposing lipid bilayers. The Sec1/Munc18 (SM family of proteins play an essential role in SNARE-mediated membrane fusion, and like the SNAREs are conserved through evolution from yeast to humans. The SM protein Vps45 is required for the formation of yeast endosomal SNARE complexes and is thus essential for traffic through the endosomal system. Here we report that, in addition to its role in regulating SNARE complex assembly, Vps45 regulates cellular levels of its SNARE binding partners: the syntaxin Tlg2 and the v-SNARE Snc2: Cells lacking Vps45 have reduced cellular levels of Tlg2 and Snc2; and elevation of Vps45 levels results in concomitant increases in the levels of both Tlg2 and Snc2. As well as regulating traffic through the endosomal system, the Snc v-SNAREs are also required for exocytosis. Unlike most vps mutants, cells lacking Vps45 display multiple growth phenotypes. Here we report that these can be reversed by selectively restoring Snc2 levels in vps45 mutant cells. Our data indicate that as well as functioning as part of the machinery that controls SNARE complex assembly, Vps45 also plays a key role in determining the levels of its cognate SNARE proteins; another key factor in regulation of membrane traffic.

    Full Text Available Myosin VI (MVI is a unique motor protein moving towards the minus end of actin filaments unlike other known myosins. Its important role has recently been postulated for striated muscle and myogenic cells. Since MVI functions through interactions of C-terminal globular tail (GT domain with tissue specific partners, we performed a search for MVI partners in myoblasts and myotubes using affinity chromatography with GST-tagged MVI-GT domain as a bait. A kinase anchoring protein 9 (AKAP9, a regulator of PKA activity, was identified by means of mass spectrometry as a possible MVI interacting partner both in undifferentiated and differentiating myoblasts and in myotubes. Coimmunoprecipitation and proximity ligation assay confirmed that both proteins could interact. MVI and AKAP9 colocalized at Rab5 containing early endosomes. Similarly to MVI, the amount of AKAP9 decreased during myoblast differentiation. However, in MVI-depleted cells, both cAMP and PKA levels were increased and a change in the MVI motor-dependent AKAP9 distribution was observed. Moreover, we found that PKA phosphorylated MVI-GT domain, thus implying functional relevance of MVI-AKAP9 interaction. We postulate that this novel interaction linking MVI with the PKA pathway could be important for targeting AKAP9-PKA complex within cells and/or providing PKA to phosphorylate MVI tail domain.

    The xeroderma pigmentosum C protein complex (XPC) recognizes a variety of environmentally induced DNA lesions and is the key in initiating their repair by the nucleotide excision repair (NER) pathway. When bound to a lesion, XPC flips two nucleotide pairs that include the lesion out of the DNA duplex, yielding a productively bound complex that can lead to successful lesion excision. Interestingly, the efficiencies of NER vary greatly among different lesions, influencing their toxicity and mutagenicity in cells. Though differences in XPC binding may influence NER efficiency, it is not understood whether XPC utilizes different mechanisms to achieve productive binding with different lesions. Here, we investigated the well-repaired 10R-(+)-cis-anti-benzo[a]pyrene-N2-dG (cis-B[a]P-dG) DNA adduct in a duplex containing normal partner C opposite the lesion. This adduct is derived from the environmental pro-carcinogen benzo[a]pyrene and is likely to be encountered by NER in the cell. We have extensively investigated its binding to the yeast XPC orthologue, Rad4, using umbrella sampling with restrained molecular dynamics simulations and free energy calculations. The NMR solution structure of this lesion in duplex DNA has shown that the dC complementary to the adducted dG is flipped out of the DNA duplex in the absence of XPC. However, it is not known whether the “pre-flipped” base would play a role in its recognition by XPC. Our results show that Rad4 first captures the displaced dC, which is followed by a tightly coupled lesion-extruding pathway for productive binding. This binding path differs significantly from the one deduced for the small cis-syn cyclobutane pyrimidine dimer lesion opposite mismatched thymines [MuH., (2015) Biochemistry, 54(34), 5263−726270861]. The possibility of multiple paths that lead to productive binding to XPC is consistent with the versatile lesion recognition by XPC that is required for successful NER. PMID:28460163

    The bacterial phage shock protein (Psp) system is a highly conserved cell envelope stress response required for virulence in Yersinia enterocolitica and Salmonella enterica. In non-inducing conditions the transcription factor PspF is inhibited by an interaction with PspA. In contrast, PspA associates with the cytoplasmic membrane proteins PspBC during inducing conditions. This has led to the proposal that PspBC exists in an OFF state, which cannot recruit PspA, or an ON state, which can. However, nothing was known about the difference between these two states. Here, we provide evidence that it is the C-terminal domain of Y. enterocolitica PspC (PspC(CT)) that interacts directly with PspA, both in vivo and in vitro. Site-specific photocross-linking revealed that this interaction occurred only during Psp-inducing conditions in vivo. Importantly, we have also discovered that PspC(CT) can interact with the C-terminal domain of PspB (PspC(CT)·PspB(CT)). However, the PspC(CT)·PspB(CT) and PspC(CT)·PspA interactions were mutually exclusive in vitro. Furthermore, in vivo, PspC(CT) contacted PspB(CT) in the OFF state, whereas it contacted PspA in the ON state. These findings provide the first description of the previously proposed PspBC OFF and ON states and reveal that the regulatory switch is centered on a PspC(CT) partner-switching mechanism. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

  5. An inhibitory switch derepressed by pbx, hox, and Meis/Prep1 partners regulates DNA-binding by pbx1 and E2a-pbx1 and is dispensable for myeloid immortalization by E2a-pbx1.

    The Pbx/Exd family of homeodomain (HD) proteins contribute to the transcriptional and developmental roles of other Hox and Meis/Prep1/Hth HD proteins through heterodimer formation. E2a-Pbx1 is an oncogenic derrivative of Pbx1 produced by the t(1;19) translocation in pediatric pre-B cell acute lymphoblastic leukemia. E2a-Pbx1 heterodimerizes with Hox but not with Meis/Prep1 proteins, produces acute myeloid leukemia in mice, and blocks differentiation of cultured murine myeloid progenitors. Here, we characterize negative and positive regulatory sequences that flank the Pbx1 HD and determine their importance for myeloid immortalization by E2a-Pbx1. A 25 residue predicted alpha helix preceding the Pbx1 HD bound the HD and prevented both its binding to DNA and its ability to heterodimerize with Hox proteins. Addition of 39 residues N-terminal to this inhibitory helix exposed a Pbx dimerization interface that orchestrated cooperative DNA-binding of E2a-Pbx1 and all Pbx proteins as homodimers and heterdimers. Sequences inhibiting DNA-binding and mediating Pbx dimerization coincided with those reported to have nuclear export function. An additional 103 residues N-terminal to the Pbx dimerization interface restored heterodimerization with Hox and Meis1/Prep1 proteins. This negative switch domain - comprised of the inhibitory helix and N-terminal regions required for its partner-mediated derepression - was dispensable for myeloid immortalization by E2a-Pbx1. While stabilizing the heterodimer, the 310 helix C-terminal to the Pbx1 HD was also dispensable for the ability of E2a-Pbx1 to heterodimerize with Hox proteins and immortalize myeloblasts. Retention of myeloid immortalization by E2a-Pbx1 proteins lacking all Pbx1 sequences N- or C-terminal to the HD indicates that Hox proteins, or a yet undefined factor that binds the Pbx1 HD and derepresses DNA-binding by the HD, cooperate with E2a-Pbx1 in myeloid immortalization.

    2011-05-15

    Intimate partner violence is a common source of physical, psychological, and emotional morbidity. In the United States, approximately 1.5 million women and 834,700 men annually are raped and/or physically assaulted by an intimate partner. Women are more likely than men to be injured, sexually assaulted, or murdered by an intimate partner. Studies suggest that one in four women is at lifetime risk. Physicians can use therapeutic relationships with patients to identify intimate partner violence, make brief office interventions, offer continuity of care, and refer them for subspecialty and community-based evaluation, treatment, and advocacy. Primary care physicians are ideally positioned to work from a preventive framework and address at-risk behaviors. Strategies for identifying intimate partner violence include asking relevant questions in patient histories, screening during periodic health examinations, and case finding in patients with suggestive signs or symptoms. Discussion needs to occur confidentially. Physicians should be aware of increased child abuse risk and negative effects on children's health observed in families with intimate partner violence. Physicians also should be familiar with local and national resources available to these patients.

  1. Pennsylvania's partnering process

    International Nuclear Information System (INIS)

    Latham, J.W.

    1996-01-01

    Pennsylvania is committed to finding a site for a low-level radioactive waste (LLRW) disposal facility through an innovative voluntary process. The Pennsylvania Department of Environmental Protection (DEP) and Chem-Nuclear Systems, Inc. (CNSI) developed the Community Partnering Plan with extensive public participation. The Community Partnering Plan outlines a voluntary process that empowers municipalities to evaluate the advantages and disadvantages of hosting the facility. DEP and CNSI began developing the Community Partnering Plan in July 1995. Before then, CNSI was using a screening process prescribed by state law and regulations to find a location for the facility. So far, approximately 78 percent of the Commonwealth has been identified as disqualified as a site for the LLRW disposal facility. The siting effort will now focus on identifying volunteer host municipalities in the remaining 22 percent of the state. This combination of technical screening and voluntary consideration makes Pennsylvania's process unique. A volunteered site will have to meet the same tough requirements for protecting people and the environment as a site chosen through the screening process. Protection of public health and safety continues to be the foundation of the state's siting efforts. The Community Partnering Plan offers a window of opportunity. If Pennsylvania does not find volunteer municipalities with suitable sites by the end of 1997, it probably will return to a technical screening process

  3. PCNA Structure and Interactions with Partner Proteins

    KAUST Repository

    Oke, Muse

    2018-01-29

    Proliferating cell nuclear antigen (PCNA) consists of three identical monomers that topologically encircle double-stranded DNA. PCNA stimulates the processivity of DNA polymerase δ and, to a less extent, the intrinsically highly processive DNA polymerase ε. It also functions as a platform that recruits and coordinates the activities of a large number of DNA processing proteins. Emerging structural and biochemical studies suggest that the nature of PCNA-partner proteins interactions is complex. A hydrophobic groove at the front side of PCNA serves as a primary docking site for the consensus PIP box motifs present in many PCNA-binding partners. Sequences that immediately flank the PIP box motif or regions that are distant from it could also interact with the hydrophobic groove and other regions of PCNA. Posttranslational modifications on the backside of PCNA could add another dimension to its interaction with partner proteins. An encounter of PCNA with different DNA structures might also be involved in coordinating its interactions. Finally, the ability of PCNA to bind up to three proteins while topologically linked to DNA suggests that it would be a versatile toolbox in many different DNA processing reactions.

    Full Text Available Developing Partnership with the stakeholders and giving space for planning, implementing, monitoring and evaluating the project for their own development is an ideal situation of participatory development. It is the popular as well as effective way of development and leads to sustainable progress. When this partnership involves strong participation from the part of women folk, the dynamism of the developmental changes takes in a drastic form. SPED III (sustainability through participation, empowerment and decentralization is a five-year project funded by CIDA and implemented by Save A Family Plan Trust India through their 28 partner NGOs and in 520 villages across India. The methodology of the SPED III is based on the decentralized planning, implementation, monitoring and evaluation. In this process, women are taking important stand and new partnership brings about fundamental changes when it is analyzed from the point of view of stakeholders. The researcher analyses and seeks to find out the comprehensive, multilevel process by which the stakeholders or partners in the development especially women develop, leverage and manage the partnership. The researcher has taken five cases of exemplary changes occurred as part of a participatory development programme. Descriptive design using case study method is applied to do in depth analysis of the cases. The primary data has collected through interview schedule and FGD with shortlisted cases and secondary through sources such as case studies and annual and bi-annual reports of the CIDA programme. The researcher observed the development of perceived need into felt need where the people especially women get involved into the village issue and the spirit that takes them into transformative leadership and partners in development. It was also observed that the when women gets resources to overcome the binding chains, they came out of the culture of silence and they move far ahead in achieving the hierarchy

    The use of the term care partner has increased, particularly in the chronic disease literature; however, the concept has not been well defined. The purpose of this concept analysis was to define and assist nurses to better understand the concept of care partner. The method by Walker and Avant was used for this literature-based concept analysis. Care partnering includes providing assistance to an individual with a health condition to meet their self-care deficits, the commitment to a care partner relationship, and the recognition that people with self-care deficits are care partners contributing to their own care. Emphasizing the care partner dyad in nursing may contribute to improved patient care outcomes both in the acute and chronic settings. It is recommended that nurses view the person with the condition as a contributor and partner in their own care in the context of a larger care partnership. Copyright © 2016 Elsevier Inc.

    2015-01-01

    Protein-ligand binding accompanies changes in the surrounding electrostatic environments of the two binding partners and may lead to changes in protonation upon binding. In cases where the complex formation results in a net transfer of protons, the binding process is pH-dependent. However, conventional free energy computations or molecular docking protocols typically employ fixed protonation states for the titratable groups in both binding partners set a priori, which are identical for the free and bound states. In this review, we draw attention to these important yet largely ignored binding-induced protonation changes in protein-ligand association by outlining physical origins and prevalence of the protonation changes upon binding. Following a summary of various theoretical methods for pKa prediction, we discuss the theoretical framework to examine the pH dependence of protein-ligand binding processes. PMID:26202905

    Morris, E J; Dyson, N J

    2001-01-01

    Studies of the retinoblastoma gene (Rb) have shown that its protein product (pRb) acts to restrict cell proliferation, inhibit apoptosis, and promote cell differentiation. The frequent mutation of the Rb gene, and the functional inactivation of pRb in tumor cells, have spurred interest in the mechanism of pRb action. Recently, much attention has focused on pRb's role in the regulation of the E2F transcription factor. However, biochemical studies have suggested that E2F is only one of many pRb-targets and, to date, at least 110 cellular proteins have been reported to associate with pRb. The plethora of pRb-binding proteins raises several important questions. How many functions does pRb possess, which of these functions are important for development, and which contribute to tumor suppression? The goal of this review is to summarize the current literature of pRb-associated proteins.

    Evaluation of partner relationships in menopausal period. A questionnaire study was performed in a group of 67 women (age: 45-55 years) and their partners. The inclusion criteria were: presence of climacteric symptoms, stable partnership, consent to research. 40 women and their spouses were included into the final study group. The investigative tool was based on 3 scales: Marriage Bond Scale (SWM); Scale of Attractiveness (SKAT); GREEN Scale evaluating intensification of menopausal symptoms and a set of additional questions concerning socio-demographical data, marital sexuality and substitute hormonal therapy. Mean age of respondents was 52 years. Most of the women demonstrated an amenorrhea (90%). Climacteric symptoms such as: hot flush, stress, depressive moods (87.5% each), musculoarticular pain (80%) occurred in various degree. 97.5% of women did not use a substitute hormonal treatment. The mean result of SWM for women and their partners scored 237 which is 79% of the total value. A correlation between exacerbation of menopausal signs and SWM score was not found. The co-attractiveness ratio counted on the basis of SKAT scale scored 30 points on average, which constitutes 74% of the maximum. Approximately 58% of the men accepted symptoms related to menopause in their partners; they tolerated changes appearing in the climacteric period, however; 100% of men did not talk about menopausal problems with their partners and did not support them in this difficult time. Men find their partners attractive in the perimenopausal period, accepting their partners and problems related to menopause. Most of the male respondents understand changes occurring in their partners, however, they do not help them to deal with them.

  4. Discriminating binding mechanisms of an intrinsically disordered protein via a multi-state coarse-grained model

    Knott, Michael; Best, Robert B.

    Many proteins undergo a conformational transition upon binding to their cognate binding partner, with intrinsically disordered proteins (IDPs) providing an extreme example in which a folding transition occurs. However, it is often not clear whether this occurs via an “induced fit” or “conformational selection” mechanism, or via some intermediate scenario. In the first case, transient encounters with the binding partner favour transitions to the bound structure before the two proteins dissociate, while in the second the bound structure must be selected from a subset of unbound structures which are in the correct state for binding, because transient encounters of the incorrect conformation with the binding partner are most likely to result in dissociation. A particularly interesting situation involves those intrinsically disordered proteins which can bind to different binding partners in different conformations. We have devised a multi-state coarse-grained simulation model which is able to capture the binding of IDPs in alternate conformations, and by applying it to the binding of nuclear coactivator binding domain (NCBD) to either ACTR or IRF-3 we are able to determine the binding mechanism. By all measures, the binding of NCBD to either binding partner appears to occur via an induced fit mechanism. Nonetheless, we also show how a scenario closer to conformational selection could arise by choosing an alternative non-binding structure for NCBD

    ''Partnering'' is an evolving relationship that could lead to a partnership or joint ownership. Babcock and Wilcox (BW) has used a variety of forms of contracting and partnering to develop global strategy for the supply of its products, both fossil and nuclear steam generating equipment. A strategic mix of consortia, strategic alliances and joint ventures has provided the impetus for BW to lead in worldwide market share in many categories, including the supply of nuclear replacement steam generators to the USA since 1992. The implication is that continuing cooperation with BW will benefit the Canadian nuclear industry. 6 refs., 12 figs

    Full Text Available During 1983-86, 225 patients were clinically diagnosed to have genital herpes (GH at our clinic. Of these, 90 men and 55 women were currently married. All the spouses were screened clinically and through standardized techniques for isolation and typing of herpes simplex virus, serological testing and Papanicolaou smear. There were 90 couples in whom at least one spouse had GH and in 38 (42% couples both partners had GH. Clinically, 49% of wives and 75% of husbands of GH patients were diagnosed to have the disease. The spouses of recurrent GH patients had a higher frequency of the disease than spouses of primary GH patients. Among spouses who were clinically asymptomatic, 40% had high serological titres suggestive of GH. Wives generally experienced more severe symptoms, especially pain in the lesions. Majority of lesions in both the partners were vesicles and ulcers. Prodromata were more among recurrent GH patients in both the partners. The frequency of recurrences wasalso similar in spouses. Seventy percent of wives and 40% of husbands could not identify any precipitating factor. Intercourse, physical stress and rich food were cited as possible factors in the remaining. All the wives had acquired the diseases through their husbands who were promiscuous. Fifty percent of husbands had been infected before marriage. Given the fact that asymptomatic carriers exist, it is better to consider all marital partners of GH as infected. Repeated and long-term follow, - up examination, particularly of wives of GH patients is therefore essential as an important socio-preventive aspect of this disease.

    Motivations of low-income substance using heterosexual Black women in New York City for having multiple sexual partners are explored in this paper. Analysis of in-depth interviews with 50 study participants demonstrates that their relationships consisted of those who had: (1) a main sex partner and a secondary sex partner; or (2) two or more “casual” partners. Individual-level motivations for extra relational sex fell into four dominant themes: sexual pleasure, partner infidelity, sex exchange and past main partners. Using a Black feminist framework, we describe how participants displayed considerable autonomy by actively forming and withdrawing from sexual relationships with men. However, women described low rates of condom use with main partners and inconsistent use of condoms with more casual sexual partners. This contradiction becomes an important area for sexual health interventions. Women who had sexual relations with only one current mate in the past two years were recruited as a monogamous comparison group. PMID:28730162

    Full Text Available Remarkable progress has been made to date in the discovery of material binding peptides and their utilization in nanotechnology, which has brought new challenges and opportunities. Nowadays phage display is a versatile tool, important for the selection of ligands for proteins and peptides. This combinatorial approach has also been adapted over the past decade to select material-specific peptides. Screening and selection of such phage displayed material binding peptides has attracted great interest, in particular because of their use in nanotechnology. Phage display selected peptides are either synthesized independently or expressed on phage coat protein. Selected phage particles are subsequently utilized in the synthesis of nanoparticles, in the assembly of nanostructures on inorganic surfaces, and oriented protein immobilization as fusion partners of proteins. In this paper, we present an overview on the research conducted on this area. In this review we not only focus on the selection process, but also on molecular binding characterization and utilization of peptides as molecular linkers, molecular assemblers and material synthesizers.

    2002-07-01

    The semiconductor foundry took off in 1990 with an annual capacity of less than 0.1M 8-inch-equivalent wafers at the 2-mm node. In 2000, the annual capacity rose to more than 10M. Initially, the technology practiced at foundries was 1 to 2 generations behind that at integrated device manufacturers (IDMs). Presently, the progress in 0.13-mm manufacturing goes hand-in-hand with any of the IDMs. There is a two-order of magnitude rise in output and the progress of technology development outpaces IDMs. What are the reasons of the success? Is it possible to sustain the pace? This paper shows the quick rise of foundries in capacity, sales, and market share. It discusses the their uniqueness which gives rise to advantages in conjunction with challenges. It also shows the role foundries take with their customer partners and supplier partners, their mutual dependencies, as well as expectations. What role then does lithography play in the foundries? What are the lithographic challenges to sustain the pace of technology? The experience of technology development and transfer, at one of the major foundries, is used to illustrate the difficulties and progresses made. Looking into the future, as semiconductor manufacturing will become even more expensive and capital investment more prohibitive, we will make an attempt to suggest possible solutions.

    Many transcription factors (TFs) have the ability to cooperate on DNA elements as heterodimers. Despite the significance of TF heterodimerization for gene regulation, a quantitative understanding of cooperativity between various TF dimer partners and its impact on heterodimer DNA binding specificity models is still lacking. Here, we used a novel integrative approach, combining microfluidics-steered measurements of dimer-DNA assembly with mechanistic modeling of the implicated protein-protein-DNA interactions to quantitatively interrogate the cooperative DNA binding behavior of the adipogenic peroxisome proliferator-activated receptor γ (PPARγ):retinoid X receptor α (RXRα) heterodimer. Using the high throughput MITOMI (mechanically induced trapping of molecular interactions) platform, we derived equilibrium DNA binding data for PPARγ, RXRα, as well as the PPARγ:RXRα heterodimer to more than 300 target DNA sites and variants thereof. We then quantified cooperativity underlying heterodimer-DNA binding and derived an integrative heterodimer DNA binding constant. Using this cooperativity-inclusive constant, we were able to build a heterodimer-DNA binding specificity model that has superior predictive power than the one based on a regular one-site equilibrium. Our data further revealed that individual nucleotide substitutions within the target site affect the extent of cooperativity in PPARγ:RXRα-DNA binding. Our study therefore emphasizes the importance of assessing cooperativity when generating DNA binding specificity models for heterodimers. PMID:26912662

    Violence against African American women, specifically intimate partner abuse, has a significant impact on their health and well being. Intimate partner femicide and near fatal intimate partner femicide are the major causes of premature death and disabling injuries for African American women. Yet, despite this, there is a paucity of research and interventions specific and culturally relevant for these women. This article focuses on issues relevant to intimate partner violence and abuse against African American women by examining existing empirical studies of prevalence and health outcomes of intimate partner violence against women in general, plus what limited research there is about African American women, specifically. It includes a discussion of specific recommendations for research, practice, education, and policy to reduce and prevent intimate partner violence against African American women.

    Proteins need to be tightly regulated as they control biological processes in most normal cellular functions. The precise mechanisms of regulation are rarely completely understood but can involve binding of endogenous ligands and/or partner proteins at specific locations on a protein that can modulate function. Often, these additional secondary binding sites appear separate to the primary binding site, which, for example for an enzyme, may bind a substrate. In previous work, we have uncovered several examples in which secondary binding sites were discovered on proteins using fragment screening approaches. In each case, we were able to establish that the newly identified secondary binding site was biologically relevant as it was able to modulate function by the binding of a small molecule. In this study, we investigate how often secondary binding sites are located on proteins by analyzing 24 protein targets for which we have performed a fragment screen using X-ray crystallography. Our analysis shows that, surprisingly, the majority of proteins contain secondary binding sites based on their ability to bind fragments. Furthermore, sequence analysis of these previously unknown sites indicate high conservation, which suggests that they may have a biological function, perhaps via an allosteric mechanism. Comparing the physicochemical properties of the secondary sites with known primary ligand binding sites also shows broad similarities indicating that many of the secondary sites may be druggable in nature with small molecules that could provide new opportunities to modulate potential therapeutic targets.

    2016-01-01

    ABSTRACT Cells are interactive living systems where proteins movements, interactions and regulation are substantially free from centralized management. How protein physico‐chemical and geometrical properties determine who interact with whom remains far from fully understood. We show that characterizing how a protein behaves with many potential interactors in a complete cross‐docking study leads to a sharp identification of its cellular/true/native partner(s). We define a sociability index, or S‐index, reflecting whether a protein likes or not to pair with other proteins. Formally, we propose a suitable normalization function that accounts for protein sociability and we combine it with a simple interface‐based (ranking) score to discriminate partners from non‐interactors. We show that sociability is an important factor and that the normalization permits to reach a much higher discriminative power than shape complementarity docking scores. The social effect is also observed with more sophisticated docking algorithms. Docking conformations are evaluated using experimental binding sites. These latter approximate in the best possible way binding sites predictions, which have reached high accuracy in recent years. This makes our analysis helpful for a global understanding of partner identification and for suggesting discriminating strategies. These results contradict previous findings claiming the partner identification problem being solvable solely with geometrical docking. Proteins 2016; 85:137–154. © 2016 Wiley Periodicals, Inc.

  8. Teleportation with Multiple Accelerated Partners

    2015-01-01

    As the current revolution in communication is underway, quantum teleportation can increase the level of security in quantum communication applications. In this paper, we present a quantum teleportation procedure that capable to teleport either accelerated or non-accelerated information through different quantum channels. These quantum channels are based on accelerated multi-qubit states, where each qubit of each of these channels represents a partner. Namely, these states are the W state, Greenberger–Horne–Zeilinger (GHZ) state, and the GHZ-like state. Here, we show that the fidelity of teleporting accelerated information is higher than the fidelity of teleporting non-accelerated information, both through a quantum channel that is based on accelerated state. Also, the comparison among the performance of these three channels shows that the degree of fidelity depends on type of the used channel, type of the measurement, and value of the acceleration. The result of comparison concludes that teleporting information through channel that is based on the GHZ state is more robust than teleporting information through channels that are based on the other two states. For future work, the proposed procedure can be generalized later to achieve communication through a wider quantum network. (paper)

  9. Sex Differences in Attitudes toward Partner Infidelity

    2013-10-01

    Full Text Available Sex differences in reactions to partner infidelity have often been studied by comparing emotional reactions to scenarios of sexual versus emotional infidelity. Men, relative to women, tend to react with more distress to partner sexual infidelity than to emotional infidelity. Evolutionary theorists interpret this difference as evidence of sexually dimorphic selection pressures. In contrast, focusing only on the simple effects within each sex, social-cognitive theorists suggest that men and women do not differ in their reactions to partner infidelity. As evidenced by recent rival meta-analytic reports, these diverging perspectives remain largely unresolved and contentious. The present study was designed to take a new approach by measuring attitudes toward partner infidelity. Results were consistent with the evolutionary perspective: Men, to a significantly larger degree than women, evaluated partner sexual infidelity more negatively than emotional infidelity.

    Cooley, Eileen L; Adorno, Gail

    2016-01-01

    in the 21st century, as more women are employed full-time and couples increasingly share egalitarian values, more women continue employment after their partners have voluntarily retired. However, we know very little about the experiences of this growing population of women. We asked working women with retired partners to share their advice for other women who may face this developmental transition. Open-ended responses from 97 women were analyzed to identify pertinent issues and themes. Four primary content areas were identified: time management, division of household labor, financial planning, and communication. Communication between partners was both a topic of concern as well as the solution suggested to resolve conflicts or differences that may arise when women live with a retired partner. It is expected that future changes in the workforce and improvements in the gender balance within relationships will continue to impact experiences for working women with retired partners.

  12. Accurate prediction of peptide binding sites on protein surfaces.

    Directory of Open Access Journals (Sweden)

    Evangelia Petsalaki

    2009-03-01

    Full Text Available Many important protein-protein interactions are mediated by the binding of a short peptide stretch in one protein to a large globular segment in another. Recent efforts have provided hundreds of examples of new peptides binding to proteins for which a three-dimensional structure is available (either known experimentally or readily modeled but where no structure of the protein-peptide complex is known. To address this gap, we present an approach that can accurately predict peptide binding sites on protein surfaces. For peptides known to bind a particular protein, the method predicts binding sites with great accuracy, and the specificity of the approach means that it can also be used to predict whether or not a putative or predicted peptide partner will bind. We used known protein-peptide complexes to derive preferences, in the form of spatial position specific scoring matrices, which describe the binding-site environment in globular proteins for each type of amino acid in bound peptides. We then scan the surface of a putative binding protein for sites for each of the amino acids present in a peptide partner and search for combinations of high-scoring amino acid sites that satisfy constraints deduced from the peptide sequence. The method performed well in a benchmark and largely agreed with experimental data mapping binding sites for several recently discovered interactions mediated by peptides, including RG-rich proteins with SMN domains, Epstein-Barr virus LMP1 with TRADD domains, DBC1 with Sir2, and the Ago hook with Argonaute PIWI domain. The method, and associated statistics, is an excellent tool for predicting and studying binding sites for newly discovered peptides mediating critical events in biology.

    2009-11-01

    This study of a predominantly Hispanic sample of 92 male and 140 female college students examines both gender symmetry in intimate partner violence (IPV) and inconsistent relationships found in previous studies between sexist attitudes and IPV. Results indicate that although comparable numbers of men and women perpetrate and are victimized in their relationships with intimate partners, the path models suggest that women's violence tends to be in reaction to male violence, whereas men tend to initiate violence and then their partners respond with violence. Benevolent sexism was shown to have a protective effect against men's violence toward partners. Findings highlight the importance of studying women's violence not only in the context of men's violence but also within a broader sociocultural context.

This was a questionnaire-based cohort study that took place at a large tertiary hospital gynecology unit, which covered two sites. Fifty-one partners of women who had surgically diagnosed endometriosis agreed to participate in the study and returned completed surveys. Ninety-two percent (n = 46) of partners reported negative feelings about the diagnosis of endometriosis. Seventy percent (n = 35) reported that endometriosis affected their day-to-day life either moderately or severely. Over half (52%) also felt that their finances were affected. Only 34% (n = 17) of partners felt that health professionals had engaged them in decision-making processes and had been supportive of them. Eighty percent (n = 40) of partners reported that they had received no information about the impact of endometriosis on couples. Partners reported a significant affect on their sex life (74%) and their relationship as a whole (56%). Participants whose relationships had been affected by endometriosis had also more likely had their day-to-day life (P = 0.027), sex life (P = 0.001), and finances (P = 0.002) affected. Overall, our findings suggest that endometriosis can have a significant impact on partners with respect to day-to-day living, finances, sex lives, and relationships. Improvements can be made to engage partners in the treatment process, and to provide better education, support, and holistic management to women and families who suffer with endometriosis. © 2017 Japan Society of Obstetrics and Gynecology.

    Now that the public private partnerships are seen to be the way forward in solar electrification in developing countries, it is important to question who will be the private partner in the partnership? For decentralized energy technologies such as solar home systems, that are being disseminated to vast numbers of highly dispersed end-users, the private partners of today are the hundreds or thousands of often non specialized local entrepreneurs. The public private partnerships of tomorrow should be reoriented accordingly. (authors)

    Full Text Available Binding operations are primarily ascribed to cortex or similarly complex avian structures. My experiments show that the zebrafish, a lower vertebrate lacking cortex, supports visual feature binding of form and motion for the purpose of social behavior. These results challenge the notion that feature binding may require highly evolved neural structures and demonstrate that the nervous system of lower vertebrates can afford unexpectedly complex computations.

    The prevention of intimate partner violence is a desirable individual and public health goal for society. The purpose of this study is to provide a comprehensive assessment of adolescent risk factors for partner violence in order to inform the development of evidence-based prevention strategies. We utilize data from the Rochester Youth Development Study, a two decade long prospective study of a representative community sample of 1000 participants that has extensive measures of adolescent characteristics, contexts, and behaviors that are potential precursors of partner violence. Using a developmental psychopathology framework, we assess self-reported partner violence perpetration in emerging adulthood (ages 20-22) and in adulthood (ages 29-30) utilizing the Conflict Tactics Scale. Our results indicate that risk factors for intimate partner violence span several developmental domains and are substantially similar for both genders. Internalizing and externalizing problem behaviors as well as early intimate relationships are especially salient for both genders. Additionally, cumulative risk across a number of developmental domains places adolescents at particularly high risk of perpetrating partner violence. Implications for prevention include extending existing prevention programs that focus on high risk groups with multiple risks for developmental disruption, as well as focusing on preventing or mitigating identified risk factors across both genders.

    2012-01-01

    Betrayal trauma theory suggests that social and cognitive development may be affected by early trauma such that individuals develop survival strategies, particularly dissociation and lack of betrayal awareness, that may place them at risk for further victimization. Several experiences of victimization in the context of relationships predicated on trust and dependence may contribute to the development of relational schema whereby abuse is perceived as normal. The current exploratory study investigates interpersonal trauma as an early experience that might impact the traits that are desired in potential romantic partners. Participants in the current study were asked to rate the desirability of several characteristics in potential romantic partners. Although loyalty was desirable to most participants regardless of their trauma history, those who reported experiences of high betrayal trauma rated loyalty less desirable than those who reported experiences of traumas that were low and medium in betrayal. Participants who reported experiences of revictimization (defined as the experience of trauma perpetrated by a close other during 2 different developmental periods) differed from participants who only reported 1 experience of high betrayal trauma in their self-reported desire for a romantic partner who possessed the traits of sincerity and trustworthiness. Preference for a partner who uses the tactic of verbal aggression was also associated with revictimization status. These preliminary findings suggest that victimization perpetrated by close others may affect partner preferences.

  13. Probing top-partners in Higgs + jets

    Banfi, Andrea; Sanz, Veronica

    2014-01-01

    Fermionic top-partners arise in models such as Composite Higgs and Little Higgs. They modify Higgs properties, in particular how the Higgs couples to top quarks. Alas, there is a low-energy cancellation acting in the coupling of the Higgs boson to gluons and photons. As a result of this cancellation, no information about the spectrum and couplings of the top-partners can be obtained in gluon fusion to Higgs, just the overall new physics scale. In this paper we show that this is not the case when hard radiation is taken into account. Indeed, differential distributions in Higgs plus jets are sensitive to the top-partner mass and coupling to the Higgs. We exploit the transverse momentum distribution of the hard jet to obtain limits on the top-partners in the 14 TeV LHC run, finding that 300 ifb of data of 14 TeV LHC are sufficient to rule out top-sector mixing angles $\\sin^2 (\\theta_R)$ > 0.05 for top-partners with masses from 300 GeV to above 2 TeV.

  14. Identifying Coevolving Partners from Paralogous Gene Families

    Directory of Open Access Journals (Sweden)

    Chen-Hsiang Yeang

    2008-01-01

    Full Text Available Many methods have been developed to detect coevolution from aligned sequences. However, all the existing methods require a one-to-one mapping of candidate coevolving partners (nucleotides, amino acids a priori. When two families of sequences have distinct duplication and loss histories, finding the one-to-one mapping of coevolving partners can be computationally involved. We propose an algorithm to identify the coevolving partners from two families of sequences with distinct phylogenetic trees. The algorithm maps each gene tree to a reference species tree, and builds a joint state of sequence composition and assignments of coevolving partners for each species tree node. By applying dynamic programming on the joint states, the optimal assignments can be identified. Time complexity is quadratic to the size of the species tree, and space complexity is exponential to the maximum number of gene tree nodes mapped to the same species tree node. Analysis on both simulated data and Pfam protein domain sequences demonstrates that the paralog coevolution algorithm picks up the coevolving partners with 60%–88% accuracy. This algorithm extends phylogeny-based coevolutionary models and make them applicable to a wide range of problems such as predicting protein-protein, protein-DNA and DNA-RNA interactions of two distinct families of sequences.

  15. Partner Market Opportunities and Relationship Stability

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Although partner market opportunities are generally considered to be important for relationship stability, they have never been measured accurately. In order to be able to test the anticipated effects of partner market opportunities, this study conceptualises them as individual opportunities for contact and interaction in concrete social contexts, like the neighbourhood, the workplace, leisure activities, etc. Using data from the German Marriage Market Survey, we first examine the impact of individual partner market opportunities on the risk of separation. Second, we examine to what extend the most frequently studied determinants of divorce and separation depend on partner market opportunities. Our results show that the number of opposite sex contacts increases the probability of separation. Sharing the same contacts with one’s partner decreases the risk of separation. Our results indicate further that reducing opposite sex contacts in the course of the relationship is partly responsible for the higher stability of longer-lasting relationships. Having a migration background is associated with fewer opposite sex contacts. This means that having a migration background would be more destabilising if these individuals did not have less opposite sex contacts than individuals without a migration background. In contrast, joint home ownership, church attendance, higher education and residing in western Germany would generally be more stabilising if these factors were not connected with more opposite sex contacts.

    Grant writing is an essential skill necessary to secure financial support for community programs and research projects. Increasingly, funding opportunities for translational biomedical research require studies to engage community partners, patients, or other stakeholders in the research process to address their concerns. However, there is little evidence on strategies to prepare teams of academic and community partners to collaborate on grants. This paper presents the description and formative evaluation of a two-part community-academic partnered grant writing series designed to help community organizations and academic institutions build infrastructure for collaborative research projects using a partnered approach. The first phase of the series was a half-day workshop on grant readiness, which was open to all interested community partners. The second phase, open only to community-academic teams that met eligibility criteria, was a 12-week session that covered partnered grant writing for foundation grants and National Institutes of Health grants. Participants in both phases reported an increase in knowledge and self-efficacy for writing partnered proposals. At 1-year follow-up, participants in Phase 2 had secured approximately $1.87 million in funding. This community-academic partnered grant writing series helped participants obtain proposal development skills and helped community-academic teams successfully compete for funding. © 2015 Wiley Periodicals, Inc.

  1. End binding proteins are obligatory dimers.

    Directory of Open Access Journals (Sweden)

    Indrani Sen

    Full Text Available End binding (EB proteins are responsible for the recruitment of an array of microtubule plus-end tracking proteins (+TIPs to growing microtubules ends. EBs encompass an N-terminal calponin homology domain that confers microtubule tip tracking activity to the protein. The C-terminal domain of EBs contains a coiled coil that mediates the parallel dimerization of EB monomers. This part of the protein is also responsible for partner binding. While dimerization is not essential for microtubule tip tracking by EBs it is a prerequisite for +TIP partner binding. The concentration of EBs in cells has been estimated to be in the range of hundreds of nanomoles. In contrast, in in vitro single molecule experiments EB concentrations of subnanomoles are employed. From a mechanistic point of view it is important to assess the oligomerization state of EBs at physiologically and experimentally relevant protein concentrations, in particular if the goal of a study is to model the behavior of EB-dependent dynamic +TIP networks. Here we have determined the stability of the EB1 and EB3 dimers using multi-angle light scattering and fluorescence analytical ultracentrifugation. We show that these EBs form stable dimers and do not dissociate even at very low nanomolar concentrations. The dimers remained stable at both room temperature as well as at the physiologically relevant temperature of 37°C. Together, our results reveal that EBs are obligatory dimers, a conclusion that has implications for the mechanistic understanding of these key proteins involved in the orchestration of dynamic protein networks at growing microtubule ends.

  2. Consequences of Partner Incarceration for Women's Employment.

    Research has documented the limited opportunities men have to earn income while in prison and the barriers to securing employment and decent wages upon release. However, little research has considered the relationship between men's incarceration and the employment of the women in their lives. Economic theory suggests that family members of incarcerated individuals may attempt to smooth income fluctuation resulting from incarceration by increasing their labor supply. This study used data from the Fragile Families and Child Wellbeing Study ( N = 3,780) to investigate how men's incarceration is associated with the number of hours their female partners work as well as variation in this association. Results showed that, on average, women's hours of work were not significantly impacted by the incarceration of their partners. However, there was a positive relationship between partner incarceration and employment among more advantaged groups of women (e.g., married women, white women).

    Full Text Available Intimate partner violence has kept being one of the major societal issues in our country over the past year. It is absolutely necessary to intervene in this substantially psychological issue multi-directionally. In order to intervene in the problem from psychological aspect, it is important to estimate and interpret the risk factors for intimate partner violence. Therefore in the current study, ‘I-cube theory’ which is about the risk factors for intimate partner violence has been explained first. Afterwards, the findings of content analysis which was obtained from newspaper reports about femicide in 2013 have been shown and these findings have been discussed within the context of I-cube theory, respectively. Finally, solutions to prevent this violence has been suggested.

    Rosenfeld, Elian A.; Miller, Elizabeth; Zhao, Xinhua; Sileanu, Florentina E.; Mor, Maria K.; Borrero, Sonya

    2017-01-01

    Background Male partner reproductive coercion is defined as male partners' attempts to promote pregnancy through interference with women’s contraceptive behaviors and reproductive decision making. Male partners may try to promote pregnancy through birth control sabotage such as taking away or destroying their partners' contraceptives, refusing to wear condoms, and/or verbally pressuring their partners to abstain from contraceptive use. Reproductive coercion is associated with an elevated risk for unintended pregnancy. Women experiencing intimate partner violence, racial/ethnic minorities and those of lower socioeconomic status, are more likely to experience reproductive coercion. Women veterans who use Veterans Affairs (VA) for health care may be particularly vulnerable to reproductive coercion as they are disproportionally from racial/ethnic minority groups and experience high rates of intimate partner violence. Objectives We sought to examine the prevalence, correlates, and impact of reproductive coercion among women veterans served by the VA healthcare system. Study Design We analyzed data from a national telephone survey of women veterans aged 18–44, with no history of sterilization or hysterectomy, who had received care within VA in the prior 12 months. Participants who had sex with men in the last year were asked if they experienced male partner reproductive coercion. Adjusted logistic regression was used to examine the relationship between participant characteristics and male partner reproductive coercion and the relationship between reproductive coercion and the outcomes of contraceptive method used at last sex, and pregnancy and unintended pregnancy in the last year. Results Among the 1,241 women veterans in our study cohort, 11% reported experiencing male partner reproductive coercion in the past year. Black women, younger women, and single women were more likely to report reproductive coercion than their white, older, and married counterparts. Women

  10. On the benzodiazepine binding pocket in GABAA receptors.

    Berezhnoy, Dmytro; Nyfeler, Yves; Gonthier, Anne; Schwob, Hervé; Goeldner, Maurice; Sigel, Erwin

    2004-01-30

    Benzodiazepines are used for their sedative/hypnotic, anxiolytic, muscle relaxant, and anticonvulsive effects. They exert their actions through a specific high affinity binding site on the major inhibitory neurotransmitter receptor, the gamma-aminobutyric acid, type A (GABA(A)) receptor channel, where they act as positive allosteric modulators. To start to elucidate the relative positioning of benzodiazepine binding site ligands in their binding pocket, GABA(A) receptor residues thought to reside in the site were individually mutated to cysteine and combined with benzodiazepine analogs carrying substituents reactive to cysteine. Direct apposition of such reactive partners is expected to lead to an irreversible site-directed reaction. We describe here the covalent interaction of alpha(1)H101C with a reactive group attached to the C-7 position of diazepam. This interaction was studied at the level of radioactive ligand binding and at the functional level using electrophysiological methods. Covalent reaction occurs concomitantly with occupancy of the binding pocket. It stabilizes the receptor in its allosterically stimulated conformation. Covalent modification is not observed in wild type receptors or when using mutated alpha(1)H101C-containing receptors in combination with the reactive ligand pre-reacted with a sulfhydryl group, and the modification rate is reduced by the binding site ligand Ro15-1788. We present in addition evidence that gamma(2)Ala-79 is probably located in the access pathway of the ligand to its binding pocket.

  15. Strategy Guideline: Partnering for High Performance Homes

    Energy Technology Data Exchange (ETDEWEB)

    Prahl, D.

    2013-01-01

    High performance houses require a high degree of coordination and have significant interdependencies between various systems in order to perform properly, meet customer expectations, and minimize risks for the builder. Responsibility for the key performance attributes is shared across the project team and can be well coordinated through advanced partnering strategies. For high performance homes, traditional partnerships need to be matured to the next level and be expanded to all members of the project team including trades, suppliers, manufacturers, HERS raters, designers, architects, and building officials as appropriate. In an environment where the builder is the only source of communication between trades and consultants and where relationships are, in general, adversarial as opposed to cooperative, the chances of any one building system to fail are greater. Furthermore, it is much harder for the builder to identify and capitalize on synergistic opportunities. Partnering can help bridge the cross-functional aspects of the systems approach and achieve performance-based criteria. Critical success factors for partnering include support from top management, mutual trust, effective and open communication, effective coordination around common goals, team building, appropriate use of an outside facilitator, a partnering charter progress toward common goals, an effective problem-solving process, long-term commitment, continuous improvement, and a positive experience for all involved.

  16. Monotop signature from a fermionic top partner

    Gonçalves, Dorival; Kong, Kyoungchul; Sakurai, Kazuki; Takeuchi, Michihisa

    2018-01-01

    We investigate monotop signatures arising from phenomenological models of fermionic top partners, which are degenerate in mass and decay into a bosonic dark matter candidate, either spin 0 or spin 1. Such a model provides a monotop signature as a smoking gun, while conventional searches with t t ¯ + missing transverse momentum are limited. Two such scenarios, (i) a phenomenological third generation extradimensional model with excited top and electroweak sectors, and (ii) a model where only a top partner and a dark matter particle are added to the standard model, are studied in the degenerate mass regime. We find that in the case of extra dimension a number of different processes give rise to effectively the same monotop final state, and a great gain can be obtained in the sensitivity for this channel. We show that the monotop search can explore top-partner masses up to 630 and 300 GeV for the third generation extradimensional model and the minimal fermionic top-partner model, respectively, at the high luminosity LHC.

  1. Sexual partner preference in female Japanese macaques.

    Vasey, Paul L

    2002-02-01

    Whether animals ever exhibit a preference for same-sex sexual partners is a subject of debate. Japanese macaques represent excellent models for examining issues related to sexual preference in animals because females, in certain populations, routinely engage in both heterosexual and homosexual behavior over the course of their life spans. Multiple lines of evidence indicate that female homosexual behavior in Japanese macaques is a sexual behavior, not a sociosexual one. Additional evidence indicates that female Japanese macaques do not engage in homosexual behavior simply because acceptable male mates are unavailable or unmotivated to copulate. Patterns of sexual partner choice by female Japanese macaques that are the focus of intersexual competition indicate that females of this species choose same-sex sexual partners even when they are simultaneously presented with a motivated, opposite-sex alternative. Thus, in some populations of Japanese macaques, females prefer certain same-sex sexual partners relative to certain male mates, and vice versa. Taken together, this evidence suggests that female Japanese macaques are best characterized as bisexual in orientation, not preferentially homosexual or preferentially heterosexual.

    The aim of this research was to understand the characteristics that adults with intellectual disabilities look for in a partner. There have been numerous studies that have explored partner selection for people without intellectual disabilities, but no research that specifically identified the traits valued in a partner by people with intellectual disabilities. In-depth interviews were conducted with eleven participants across two UK sites. All participants were adults with an intellectual disability who had been in a relationship with a partner for over a year. The narratives were analysed utilizing hermeneutic phenomenology, guided by the theory of Van Manen (1990). The findings highlighted that, regardless of age, participant's relationships typically developed within a segregated environment for people with intellectual disabilities over the past 10 years. People with intellectual disabilities expressed a wish to be loved, to be treated kindly and to have companionship. However, they did not place high value on attributes such as financial security, social status or intelligence. The research demonstrated how poorly integrated people with intellectual disabilities are within mainstream society. Desired characteristics and expectations for participant's relationships were rooted in a shared history and culture, which was shaped by their intellectual disability and support needs. © 2016 John Wiley & Sons Ltd.

    Full Text Available Introduction: We examine the association between self-reported alcohol misuse and alcohol usewithin 2 hours of having sex and the number of sexual partners among a sample of African-Americanand Latino emergency department (ED patients.Methods: Cross-sectional data were collected prospectively from a randomized sample of all EDpatients during a 5-week period. In face-to-face interviews, subjects were asked to report their alcoholuse and number of sexual partners in the past 12 months. Data were analyzed using multiple variablenegative binomial regression models, and effect modification was assessed through inclusion ofinteraction terms.Results: The 395 study participants reported an average of 1.4 (standard error¼0.11 sexual partnersin the past 12 months, 23% reported misusing alcohol, and 28% reported consuming alcohol beforesex. There was no statistically significant association between alcohol misuse and the number ofsexual partners; however, alcohol before sex was associated with a larger number of sexual partners inthe past year. Moreover, among those who misused alcohol, participants who reported alcohol beforesex were 3 times more likely to report a higher number of sexual partners (risk ratio¼3.2; confidenceinterval [CI]¼1.9–5.6. The association between alcohol use before sex and number of sexual partnersis dependent upon whether a person has attributes of harmful drinking over the past 12 months.Overall, alcohol use before sex increases the number of sexual partners, but the magnitude of thiseffect is significantly increased among alcohol misusers.Conclusion: Alcohol misusers and those who reported having more than 1 sexual partner were morelikely to cluster in the same group, ie, those who used alcohol before sex. Efforts to reduce the burdenof sexually transmitted diseases, including human immunodeficiency virus, and other consequences ofrisky sexual behavior in the ED population should be cognizant of the interplay of alcohol and

  11. Postpartum depression and the male partner

    Directory of Open Access Journals (Sweden)

    Anna de Magistris

    2013-04-01

    Full Text Available Background: Numerous studies have shown that postpartum depression is a phenomenon that develops in a family, social and economic context capable of influencing its course. A predominant role in the onset of the pathology is played by the relationship of the couple, but up to now few studies have been carried out on the role of the partner of the depressed mother and on the interactions between the two partners, that is, on how maternal depression influences the behaviour of the male partner and is in turn influenced, and how the depression of both parents, and not only that of the mother, influences the neuropsychic development of the child and the interactions between the child and the outside world. Objectives: The objectives are to examine the literature to arrive at an understanding of how the father figure develops during the pregnancy and how postpartum depression impacts on the couple’s relationship and the care of the children by both partners. Materials and methods: This article presents a review of recent literature on the subject through a search for articles in Pubmed and Sciencedirect (keywords: men, postpartum depression, fathers, couple, prediction, detection, and by referring to classic texts in the fields of psychiatry and psychotherapy on the development of the parental figures. Conclusions: Although up to now the literature on the consequences of postpartum depression on the couple is scanty, the data collected allow us to affirm that it is not a problem that concerns only the mother, but one that has an impact on the entire family, on the child and the partner, triggering a chain reaction of maladjustment and distress that may lead to separation and destruction of the family unit with important repercussions on society as a whole.

  12. Willingness to express emotion depends upon perceiving partner care.

    2017-06-01

    Two studies document that people are more willing to express emotions that reveal vulnerabilities to partners when they perceive those partners to be more communally responsive to them. In Study 1, participants rated the communal strength they thought various partners felt toward them and their own willingness to express happiness, sadness and anxiety to each partner. Individuals who generally perceive high communal strength from their partners were also generally most willing to express emotion to partners. Independently, participants were more willing to express emotion to particular partners whom they perceived felt more communal strength toward them. In Study 2, members of romantic couples independently reported their own felt communal strength toward one another, perceptions of their partners' felt communal strength toward them, and willingness to express emotions (happiness, sadness, anxiety, disgust, anger, hurt and guilt) to each other. The communal strength partners reported feeling toward the participants predicted the participants' willingness to express emotion to those partners. This link was mediated by participants' perceptions of the partner's communal strength toward them which, itself, was a joint function of accurate perceptions of the communal strength partners had reported feeling toward them and projections of their own felt communal strength for their partners onto those partners.

    The objectives of this study were as follows: (1) to determine the extent of agreement between adolescents' perceptions of sex-partner concurrency (having a partner who has other overlapping sexual partnerships) and their partners' self-reported concurrency, and (2) to identify the relationship-level factors associated with agreement. Adolescents ages 14 to 19 years, along with their main sex partners, were recruited from a primary care clinic and a public sexually transmitted disease clinic and interviewed separately about their own concurrency status and their perception of their partner's concurrency status. Information from both participants and their partners were included in this analysis (N = 90 couples). This sample consisted of African-American, sexually experienced heterosexual couples. For males and females who perceived their partner not to have other partners, 16% and 37% of their sex partners reported having other partners, respectively. Of males and females who perceived their partner to have other partners, 80% and 39% of their sex partners reported not having other partners, respectively. Multivariate logistic regression revealed that adolescents who had been with their partners for more than 6 months and considered themselves more emotionally close were nearly twice as likely to agree on concurrency. Among adolescent couples, agreement between perceptions of sex-partner concurrency and partner-reported behavior was low. To the extent that partner self-reports are accurate, individuals who presume that they are in a mutually monogamous relationship often underestimate their own sexually transmitted disease risk. To appropriately tailor risk reduction messages, prevention efforts need to consider adolescents' perceptions of concurrent sex partners.

    In this study, we reported that small glutamine-rich TPR-containing protein (SGT) interacted with not only Hsp90α but also Hsp90β. Confocal analysis showed that treatment of cells with Hsp90-specific inhibitor geldanamycin (GA) disrupted the interaction of SGT with Hsp90β and this contributed to the increase of nuclear localization of SGT in HeLa cells. The increased nuclear localization of SGT was further confirmed by the Western blotting in GA-treated HeLa cells and H1299 cells. In our previous study, SGT was found to be a new pro-apoptotic factor, so we wondered whether the sub-cellular localization of SGT was related with cell apoptosis. By confocal analysis we found that the nuclear import of SGT was significantly increased in STS-induced apoptotic HeLa cells, which implied that the sub-cellular localization of SGT was closely associated with Hsp90β and apoptosis

  18. Ants use partner specific odors to learn to recognize a mutualistic partner.

    Directory of Open Access Journals (Sweden)

    Masaru K Hojo

    Full Text Available Regulation via interspecific communication is an important for the maintenance of many mutualisms. However, mechanisms underlying the evolution of partner communication are poorly understood for many mutualisms. Here we show, in an ant-lycaenid butterfly mutualism, that attendant ants selectively learn to recognize and interact cooperatively with a partner. Workers of the ant Pristomyrmex punctatus learn to associate cuticular hydrocarbons of mutualistic Narathura japonica caterpillars with food rewards and, as a result, are more likely to tend the caterpillars. However, the workers do not learn to associate the cuticular hydrocarbons of caterpillars of a non-ant-associated lycaenid, Lycaena phlaeas, with artificial food rewards. Chemical analysis revealed cuticular hydrocarbon profiles of the mutualistic caterpillars were complex compared with those of non-ant-associated caterpillars. Our results suggest that partner-recognition based on partner-specific chemical signals and cognitive abilities of workers are important mechanisms underlying the evolution and maintenance of mutualism with ants.

  19. Number of sexual partners and sexual assertiveness predict sexual victimization: do more partners equal more risk?

    2011-01-01

    In previous studies, number of sexual partners and sexual assertiveness were examined as independent risk factors for sexual victimization among college women. Using a sample of 335 college women, this study examined the interaction of number of sexual partners and sexual assertiveness on verbal sexual coercion and rape. Approximately 32% of the sample reported unwanted sexual intercourse, 6.9% (n = 23) experienced verbal sexual coercion, 17.9% (n = 60) experienced rape, and 7.2% (n = 24) experienced both. As number of sexual partners increased, instances of verbal sexual coercion increased for women low in relational sexual assertiveness but not for women high in relational sexual assertiveness. A similar relationship was not found for rape. Among women who experienced both verbal sexual coercion and rape, increases in number of partners in the context of low refusal and relational assertiveness were associated with increases in verbal sexual coercion and rape. Findings suggest sexual assertiveness is related to fewer experiences of sexual coercion.

    This study examined the association between relationship adjustment and discrepant alcohol use among lesbian women and their same-sex intimate partners after controlling for verbal and physical aggression. Lesbian women ( N = 819) who were members of online marketing research panels completed an online survey in which they reported both their own and same-sex intimate partner's alcohol use, their relationship adjustment, and their own and their partner's physical aggression and psychological aggression (i.e., verbal aggression and dominance/isolation). Partners' alcohol use was moderately correlated. Discrepancy in alcohol use was associated with poorer relationship adjustment after controlling for psychological aggression and physical aggression. Results are discussed in terms of the similarity and differences with previous literature primarily focused on heterosexual couples.

    2013-12-01

    There is dearth of knowledge and research about the role of empowerment, partners' behaviours and intimate partner physical violence (IPPV) among married women in Uganda. This paper examined the influence of women's empowerment and partners' behaviours on IPPV among married women in Uganda. The 2011 Uganda Demographic and Health Survey data were used, selecting a weighted sample of 1,307 women in union considered for the domestic violence module. Cross tabulations (chi-square tests) and multivariate logistic regressions were used to identify factors associated with IPPV. The prevalence of IPPV among women in union in Uganda is still high (41%). Women's occupation was the only measure of empowerment that was significantly associated with IPPV, where women in professional employment were less likely to experience IPPV. Women from wealthy households were less likely to experience IPPV. IPPV was more likely to be reported by women who had ever had children and witnessed parental IPPV. IPPV was also more likely to be reported by women whose husbands or partners: accused them of unfaithfulness, did not permit them to meet female friends, insisted on knowing their whereabouts and sometimes or often got drunk. Women who were afraid their partners were also more likely to report IPPV. In the Ugandan context, women's empowerment as assessed by the UDHS has limited mitigating effect on IPPV in the face of partners' negative behaviours and history of witnessing parental violence.

    2009-11-01

    Full Text Available Abstract ERK signaling regulates focal adhesion disassembly during cell movement, and increased ERK signaling frequently contributes to enhanced motility of human tumor cells. We previously found that the ERK scaffold MEK Partner 1 (MP1 is required for focal adhesion disassembly in fibroblasts. Here we test the hypothesis that MP1-dependent ERK signaling regulates motility of DU145 prostate cancer cells. We find that MP1 is required for motility on fibronectin, but not for motility stimulated by serum or EGF. Surprisingly, MP1 appears not to function through its known binding partners MEK1 or PAK1, suggesting the existence of a novel pathway by which MP1 can regulate motility on fibronectin. MP1 may function by regulating the stability or expression of paxillin, a key regulator of motility.

    Purpose This longitudinal investigation examined potential risk factors for intimate partner violence (IPV) among women during pregnancy and 6 weeks postpartum. Methods A sample of 180 pregnant women was collected in order to investigate 1) whether associations between partner alcohol misuse, partner jealousy, partner suspicion of infidelity, and stress were associated with IPV victimization, 2) the indirect effects of alcohol misuse on these relationships, and 3) factors related to changes in IPV victimization over time. Results At baseline, partner alcohol misuse was associated with each type of IPV victimization and the combination of partner alcohol misuse, partner jealousy, and partner suspicion of infidelity was most strongly associated with severe physical victimization. Partner alcohol misuse mediated the relationship between partner jealousy and psychological and severe physical victimization. At follow-up, partner jealousy and stress were related to women’s psychological victimization and partner alcohol misuse was related to women’s severe physical victimization. Conclusions Findings suggest that partner alcohol misuse is a risk factor for women’s IPV victimization during pregnancy and jealousy and stress may increase risk for some types of IPV. Findings also suggest that intervention should target parents early in pregnancy in order to reduce the risk for future IPV. PMID:23053216

    We describe a facile method for mapping protein:ligand binding sites and conformational epitopes. The method uses a combination of Cys scanning mutagenesis, chemical labeling, and yeast surface display. While Ala scanning is widely used for similar purposes, often mutation to Ala (or other amino acids) has little effect on binding, except at hotspot residues. Many residues in physical contact with a binding partner are insensitive to substitution with Ala. In contrast, we show that labeling of Cys residues in a binding site consistently abrogates binding. We couple this methodology to yeast surface display and deep sequencing to map conformational epitopes targeted by both monoclonal antibodies and polyclonal sera as well as a protein:ligand binding site. The method does not require purified protein, can distinguish buried and exposed residues, and can be extended to other display formats, including mammalian cells and viruses, emphasizing its wide applicability.

    Women who experience intimate partner violence (IPV) often do not perceive themselves as abused. This study sought to estimate the health effects of unperceived IPV (uIPV), taking violence-free women as the reference, and to compare the effects of uIPV with those of perceived IPV (pIPV). We performed a cross-sectional population study through telephone interviews of 2835 women aged 18 to 70 years living in the region of Madrid and having an ongoing intimate partner relationship or contact with a former partner in the preceding year. Based on 26 questions from the Conflict Tactics Scale-1 and the Enquête Nacional sur les Violences envers les Femmes en France and the question "Do you feel abused by your partner?" a variable was constructed in three categories, namely, the absence of IPV, uIPV and pIPV. Using logistic regression, we analyzed the association between health problems, medication use, health-service utilization and IPV (perceived and unperceived) vis-à-vis the absence of IPV. There were 247 cases of uIPV and 96 of pIPV (prevalences of 8.8% and 3.4%, respectively). The multivariate analysis showed that a substantial number of the outcomes explored were associated with uIPV, pIPV, or both. The highest odds ratios (ORs) were obtained for depression (Patient Health Questionnaire-9≥10) (uIPV: OR 3.4, 95% CI 2.4-3.8; and pIPV: 4.1, 95%CI 2.5-6.8). In most problems, the ORs did not significantly differ between the two types of IPV. uIPV is 2.6 times more frequent than pIPV and is associated with at least as many health problems as pIPV.

  15. On the Interpretation of Top Partners Searches

    CERN Document Server

    Matsedonskyi, Oleksii; Wulzer, Andrea

    2014-01-01

    Relatively light Top Partners are unmistakable signatures of reasonably Natural Composite Higgs models and as such they are worth searching for at the LHC. Their phenomenology is characterized by a certain amount of model-dependence, which makes the interpretation of Top Partner experimental searches not completely straightforward especially if one is willing to take also single production into account. We describe a model-independent strategy by which the interpretation is provided on the parameter space of a Simplified Model that captures the relevant features of all the explicit constructions. The Simplified Model limits are easy to interpret within explicit models, in a way that requires no recasting and no knowledge of the experimental details of the analyses. We illustrate the method by concrete examples, among which the searches for a charge 5/3 Partner in same-sign dileptons and the searches for a charge 2/3 singlet. In each case we perform a theory recasting of the available 8 TeV Run-1 results and a...

    Inter-organizational networks represent one of the most promising practice-based approaches in public health as a way to attain resources, share knowledge, and, in turn, improve population health outcomes. However, the interdependencies and effectiveness related to the structure, management, and costs of these networks represents a critical item to be addressed. The objective of this research is to identify and determine the extent to which potential partnering patterns influence the structure of collaborative networks. This study examines data collected by PARTNER, specifically public health networks (n = 162), to better understand the structured relationships and interactions among public health organizations and their partners, in relation to collaborative activities. Combined with descriptive analysis, we focus on the composition of public health collaboratives in a series of Exponential Random Graph (ERG) models to examine the partnerships between different organization types to identify the attribute-based effects promoting the formation of network ties within and across collaboratives. We found high variation within and between these collaboratives including composition, diversity, and interactions. The findings of this research suggest common and frequent types of partnerships, as well as opportunities to develop new collaborations. The result of this analysis offer additional evidence to inform and strengthen public health practice partnerships. PMID:26445053

    To investigate the effect of intimate partner violence (IPV) on companion animal welfare. Self-selected telephone survey of people meeting the criteria. Members of the Australian public with experience of IPV and concurrent companion animal ownership were invited to telephone a researcher for a semi-structured interview. In total, 26 Australian women reported one or more companion animals in the household being verbally and/or physically abused by their male partner, usually with prolonged effects on animal behaviour; 92% indicated that they had been unwilling to discuss the animal abuse with a veterinarian. Many were unaware of animal accommodation services for people fleeing violence and those who did know about these were unwilling to use them, citing their bond with the animals as the main reason. Animals targeted for abuse were most likely to be dogs and owned by women rather than men, children or both partners. Animals can be severely affected by domestic violence situations and many people experiencing violence are unwilling to confide in veterinarians or seek help from animal shelters. © 2012 The Authors.

  19. Neutrino Masses from Neutral Top Partners

    CERN Document Server

    Batell, Brian

    2015-01-01

    We present theories of `Natural Neutrinos' in which neutral fermionic top partner fields are simultaneously the right-handed neutrinos (RHN), linking seemingly disparate aspects of the Standard Model structure: a) The RHN top partners are responsible for the observed small neutrino masses, b) They help ameliorate the tuning in the weak scale and address the little hierarchy problem, and c) The factor of $3$ arising from $N_c$ in the top-loop Higgs mass corrections is countered by a factor $3$ from the number of vector-like generations of RHN. The RHN top partners may arise in pseudo-Nambu-Goldstone-Boson (pNGB) Higgs models such as the Twin Higgs, as well as more general Composite, Little, and Orbifold Higgs scenarios, and three simple example models are presented. This framework firmly predicts a TeV-scale seesaw, as the RHN masses are bounded to be below the TeV scale by naturalness. The generation of light neutrino masses relies on a collective breaking of lepton number, allowing for comparatively large ne...

    Describe gender-based violence by intimate partners against female nurses in a sample of nurses in Andalucia, Spain. Descriptive transversal study. Hospitals and primary health care districts in Andalucia. Six hundred and twenty-two female nurses that work as nurses in the eight provinces in Andalucia (Spain). Social-demographic characteristics and presence of abuse (psychological, physical and sexual). 78.5% of the nurses were married or with a regular partner and had the economic income based on both salaries; 71.1% had a child or an elderly dependent person. It was proved that there can be a statistical association between abuse and: marital status; life together; familiar economic support and children and/or dependent elderly person. The average age was 42.5±8.1 years old (22-62 years) and presented statistical age differences comparing both groups: abused (average 44 years) and non-abused (average 41.8 years). Between the married couples studied, 21.7% of them belong to the social class I and 16.9% to the social class II. Between all studied nurses, 33.0% suffered abuse, among which 75.1% were psychologically abused. Of all the abuse cases 60% were less severe and 40% more serious. It was confirmed the presence of intimate partner violence (IPV) against nurses, which was predominantly psychological abuse, but others classes of abuse were present too.

  4. Involvement of the Tyro3 receptor and its intracellular partner Fyn signaling in Schwann cell myelination.

    During early development of the peripheral nervous system, Schwann cell precursors proliferate, migrate, and differentiate into premyelinating Schwann cells. After birth, Schwann cells envelop neuronal axons with myelin sheaths. Although some molecular mechanisms underlying myelination by Schwann cells have been identified, the whole picture remains unclear. Here we show that signaling through Tyro3 receptor tyrosine kinase and its binding partner, Fyn nonreceptor cytoplasmic tyrosine kinase, is involved in myelination by Schwann cells. Impaired formation of myelin segments is observed in Schwann cell neuronal cultures established from Tyro3-knockout mouse dorsal root ganglia (DRG). Indeed, Tyro3-knockout mice exhibit reduced myelin thickness. By affinity chromatography, Fyn was identified as the binding partner of the Tyro3 intracellular domain, and activity of Fyn is down-regulated in Tyro3-knockout mice, suggesting that Tyro3, acting through Fyn, regulates myelination. Ablating Fyn in mice results in reduced myelin thickness. Decreased myelin formation is observed in cultures established from Fyn-knockout mouse DRG. Furthermore, decreased kinase activity levels and altered expression of myelination-associated transcription factors are observed in these knockout mice. These results suggest the involvement of Tyro3 receptor and its binding partner Fyn in Schwann cell myelination. This constitutes a newly recognized receptor-linked signaling mechanism that can control Schwann cell myelination. © 2015 Miyamoto et al.

    Temporal order memories are critical for everyday animal and human functioning. Experiments and our own experience show that the binding or association of various features of an event together and the maintaining of multimodality events in sequential order are the key components of any sequential memories—episodic, semantic, working, etc. We study a robustness of binding sequential dynamics based on our previously introduced model in the form of generalized Lotka-Volterra equations. In the phase space of the model, there exists a multi-dimensional binding heteroclinic network consisting of saddle equilibrium points and heteroclinic trajectories joining them. We prove here the robustness of the binding sequential dynamics, i.e., the feasibility phenomenon for coupled heteroclinic networks: for each collection of successive heteroclinic trajectories inside the unified networks, there is an open set of initial points such that the trajectory going through each of them follows the prescribed collection staying in a small neighborhood of it. We show also that the symbolic complexity function of the system restricted to this neighborhood is a polynomial of degree L - 1, where L is the number of modalities.

    Full Text Available Introduction: Despite a recent focus on intimate partner violence (IPV among men who have sex with men (MSM, the male-male couple is largely absent from the IPV literature. Specifically, research on dyadic factors shaping IPV in male-male couples is lacking.Methods: We took a subsample of 403 gay/bisexual men with main partners from a 2011 survey of approximately 1,000 gay and bisexual men from Atlanta. Logistic regression models of recent (,12 month experience and perpetration of physical and sexual IPV examined dyadic factors, including racial differences, age differences, and social network characteristics of couples as key covariates shaping the reporting of IPV.Results: Findings indicate that men were more likely to report perpetration of physical violence if they were a different race to their main partner, whereas main partner age was associated with decreased reporting of physical violence. Having social networks that contained more gay friends was associated with significant reductions in the reporting of IPV, whereas having social networks comprised of sex partners or closeted gay friends was associated with increased reporting of IPV victimization and perpetration.Conclusion: The results point to several unique factors shaping the reporting of IPV within male-male couples and highlight the need for intervention efforts and prevention programs that focus on male couples, a group largely absent from both research and prevention efforts.

    Full Text Available The most alarming type of intimate partner violence is homicide. Violence risk assessment of intimate partner violent offenders is a common topic in police and prison contexts with the aim of preventing recidivism and fatal results. The purpose of this study was to analyze whether men who kill their intimate partner (intimate partner homicide - IPH present different risk factors from those who kill women outside of a relationship (non-intimate partner homicide - non-IPH. The crime characteristics of 30 attempted or completed IPHs that were sentenced in Catalonia (Spain between 2004 and 2009 are described. Moreover, the risk factors of 21 completed IPHs and 20 non-IPHs were compared using the RisCanvi, an actuarial risk assessment tool used in the Catalan prison context to manage inmates. Results show differences between the two types of offenders in the criminal role and recklessness, more prevalent among non-IPHs, which is consistent with research indicating that IPH offenders are similar to other homicide offenders. The difficulties faced seeking to assess and manage the risk of IPH are discussed.

    Partnered tango dance can improve balance and gait in individuals with Parkinson disease (PD). Partnered dance may allow individuals with PD to challenge balance more than non-partnered dance. Alternatively, partnered practice could reduce balance gains because the patient may rely on the partner as a balance aid when challenged. We compared effects of partnered to non-partnered dance on balance and mobility in 39 people (11 females) with mild-moderate PD (Hoehn & Yahr stages I-III). Participants were randomly assigned to partnered or non-partnered tango and attended 1-hour classes twice per week, completing 20 lessons within 10 weeks. Balance and gait were evaluated in the weeks immediately before, immediately after, and one month after the intervention. Both groups significantly improved on the Berg Balance scale, comfortable and fast as possible walking velocity and cadence. Improvements were maintained at the one-month follow-up. The non-partnered class improved as much as the partnered class; however, Partner participants expressed more enjoyment and interest in continuing. PMID:20008820

    Age at sexual debut and age gap between partners at debut are modifiable characteristics that may be related to risky sexual behaviors. Understanding any such relationships is a necessary first step toward strengthening risk interventions. Age at sexual debut and partner age gap were examined for 3,154 female and 2,713 male respondents to the 2011-2013 National Survey of Family Growth who first had intercourse before age 18. Multivariable logistic regression was used to assess associations between these measures and teenage parenthood and reporting a high lifetime number of partners (i.e., a number above the sample median). Females' odds of teenage parenthood were elevated if sexual debut occurred at ages 15-17 and involved a partner age gap of 3-4 years (odds ratio, 1.8) or more (2.0); they were reduced if debut occurred before age 15 and the gap was 3-4 years (0.8). Females' likelihood of reporting a high lifetime number of partners was negatively associated with age gap (0.4-0.7, depending on age at debut and length of age gap). Males' likelihood of reporting a large number of partners was positively associated with age gap if sexual debut was before age 15 and the gap was five or more years (1.7) or if debut was at ages 15-17 and involved a 3-4-year gap (2.0). Identifying the mechanisms underlying these associations could inform program design and implementation. Copyright © 2017 by the Guttmacher Institute.

    Internet-based programs for sexually transmitted infections (STI)/HIV partner notification have generated considerable interest as public health interventions; yet data are lacking to support widespread dissemination. We report on a clinic-based and web-based evaluation of the Colorado inSPOT online partner notification program. Clinic-based surveys were conducted at a large urban STI clinic before and after the implementation of feasible clinic interventions as well as nonclinic campaigns to promote the use of inSPOT Colorado. Questions assessed recognition and use of the site. Website statistics were provided by the inSPOT service, including the number of site hits, e-cards sent, and specific STI exposures identified on the card. Recognition and use of the service among STI clinic patients remained low (<6%) despite the interventions. Site statistics demonstrated an immediate but quickly diminishing response after placement of a banner ad on a popular gay website. Newspaper advertisements and radio public service announcements showed small increases in website use. Analysis of STIs specified on the e-cards, showed scabies and pediculosis as the most-identified STIs, accounting for nearly 30% of all e-cards sent. Clinic survey data indicated that when respondents were faced with the hypothetical situation of being diagnosed with an STI, more than 90% would notify partners in person; only 5% would use e-mail or the Internet. Our data did not support the effectiveness of the inSPOT intervention among a predominantly heterosexual population in a large urban STI clinic.

    Potential protection from violence has been suggested as an explanation for women's preferences for more masculine partners. Previous studies, however, have not considered that violence may be multi-modal, and hence come from different sources. Therefore, we tested the effect of different fears of violence (i.e. vulnerability to public crime, likelihood of within-partnership violence) on masculinity preferences of women from Colombia, a country known for its high rates of violence. Eighty-three adult heterosexual women (mean age ± SD = 26.7 ± 6.01) answered a survey that included questions about health (e.g. frequency of illnesses during the last year and during childhood), access to media (e.g. time spent watching television, frequency of internet use), education (i.e. highest level achieved) and violence perceptions. Participants' masculinity preferences for Salvadoran, European and Colombian male faces were recorded. Factor analysis revealed two different factors for the answers to questions related to violence. One factor loaded mostly on questions related to public violence and the second factor related to domestic violence. We found that women with higher scores on the domestic violence factor preferred significantly less masculine Colombian male faces. Even after controlling for participant age, education, access to media (TV and internet) and health-related factors, the domestic violence factor contributed significantly to explaining masculinity preferences. The results presented here suggest that women's preferences for masculinity may be a strategy to avoid aggressive partners and that the source of violence matters in mate choice. Women who perceive higher risks of domestic violence prefer less masculine looking partners. Using an experimental approach, we show that Colombian women who feel more in danger of violence within partnership prefer the faces of less masculine males. This was true even after controlling for women's education level

    2014-02-06

    The Arizona Governor’s Office of Energy Policy, in partnership with Tucson Electric Power (TEP), Tendril, and Next Phase Energy (NPE), formed the TEP Power Partners pilot project to demonstrate how residential customers could access their energy usage data and third party applications using data obtained from an Automatic Meter Reading (AMR) network. The project applied for and was awarded a Smart Grid Data Access grant through the U.S. Department of Energy. The project participants’ goal for Phase I is to actively engage 1,700 residential customers to demonstrate sustained participation, reduction in energy usage (kWh) and cost ($), and measure related aspects of customer satisfaction. This Demonstration report presents a summary of the findings, effectiveness, and customer satisfaction with the 15-month TEP Power Partners pilot project.

    Stewart, Donna Eileen; Vigod, Simone Natalie

    2017-06-01

    Intimate partner violence (IPV) is common worldwide and occurs in more than one-third of American women and psychiatric patients. As well as physical injuries, it may cause mental health sequelae, such as depression, anxiety, posttraumatic stress disorder, psychosis, inability to trust others, self-harm, and a host of psychosomatic conditions, that may be referred to psychiatrists. It is imperative that psychiatrists know the risk factors, how to assist disclosure of IPV, and how to safely respond. Psychiatrists must know the best evidence-based management of IPV and its mental health sequelae to best assist patients who have been exposed to IPV. Copyright © 2017 Elsevier Inc.

    Findings reported by many researchers indicate that the association between marital separation and intimate partner femicide has achieved the status of a sociological empirical generalization. The primary objective of this article is to contribute toward the cumulative development of a conflict theoretic explanation of separation- associated femicide by creating and testing a deductive conflict resolution theory that explains the empirical generalization. The causal mechanism identified in the theory is the intensity of conflict that increases with participation in adversarial and separation and divorce proceedings. Interventions logically derived from the theory are presented in the penultimate segment. Limitations are identified in the concluding segment. © The Author(s) 2016.

  12. A tool for calculating binding-site residues on proteins from PDB structures

    2009-08-01

    Full Text Available Abstract Background In the research on protein functional sites, researchers often need to identify binding-site residues on a protein. A commonly used strategy is to find a complex structure from the Protein Data Bank (PDB that consists of the protein of interest and its interacting partner(s and calculate binding-site residues based on the complex structure. However, since a protein may participate in multiple interactions, the binding-site residues calculated based on one complex structure usually do not reveal all binding sites on a protein. Thus, this requires researchers to find all PDB complexes that contain the protein of interest and combine the binding-site information gleaned from them. This process is very time-consuming. Especially, combing binding-site information obtained from different PDB structures requires tedious work to align protein sequences. The process becomes overwhelmingly difficult when researchers have a large set of proteins to analyze, which is usually the case in practice. Results In this study, we have developed a tool for calculating binding-site residues on proteins, TCBRP http://yanbioinformatics.cs.usu.edu:8080/ppbindingsubmit. For an input protein, TCBRP can quickly find all binding-site residues on the protein by automatically combining the information obtained from all PDB structures that consist of the protein of interest. Additionally, TCBRP presents the binding-site residues in different categories according to the interaction type. TCBRP also allows researchers to set the definition of binding-site residues. Conclusion The developed tool is very useful for the research on protein binding site analysis and prediction.

    2011-01-01

    Peptide recognition modules (PRMs) play critical roles in cellular processes, including differentiation, proliferation and cytoskeleton organization. PRMs normally bind to short linear motifs in protein ligands, and by so doing recruit proteins into signaling complexes. Based on the binding specificity profile of a PRM, one can predict putative natural interaction partners by searching genome databases. Candidate interaction partners can in turn provide clues to assemble potential in vivo protein complexes that the PRM may be involved with. Combinatorial peptide libraries have proven to be effective tools for profiling the binding specificities of PRMs. Herein, we describe high-throughput methods for the expression and purification of PRM proteins and the use of peptide-phage libraries for PRM specificity profiling. These high-throughput methods greatly expedite the study of PRM families on a genome-wide scale.

    2014-03-01

    Full Text Available Interpersonal touch is of paramount importance in human social bonding and close relationships, allowing a unique channel for affect communication. So far the effect of touch on human physiology has been studied at an individual level. The present study aims at extending the study of affective touch from isolated individuals to truly interacting dyads. We have designed an ecological paradigm where romantic partners interact only via touch and we manipulate their empathic states. Simultaneously, we collected their autonomic activity (skin conductance, pulse, respiration. 14 couples participated to the experiment. We found that interpersonal touch increased coupling of electrodermal activity between the interacting partners, regardless the intensity and valence of the emotion felt. In addition, physical touch induced strong and reliable changes in physiological states within individuals. These results support an instrumental role of interpersonal touch for affective support in close relationships. Furthermore, they suggest that touch alone allows the emergence of a somatovisceral resonance between interacting individuals, which in turn is likely to form the prerequisites for emotional contagion and empathy.

  17. Binding matrix: a novel approach for binding site recognition.

    Kim, Jan T; Gewehr, Jan E; Martinetz, Thomas

    2004-06-01

    Recognition of protein-DNA binding sites in genomic sequences is a crucial step for discovering biological functions of genomic sequences. Explosive growth in availability of sequence information has resulted in a demand for binding site detection methods with high specificity. The motivation of the work presented here is to address this demand by a systematic approach based on Maximum Likelihood Estimation. A general framework is developed in which a large class of binding site detection methods can be described in a uniform and consistent way. Protein-DNA binding is determined by binding energy, which is an approximately linear function within the space of sequence words. All matrix based binding word detectors can be regarded as different linear classifiers which attempt to estimate the linear separation implied by the binding energy function. The standard approaches of consensus sequences and profile matrices are described using this framework. A maximum likelihood approach for determining this linear separation leads to a novel matrix type, called the binding matrix. The binding matrix is the most specific matrix based classifier which is consistent with the input set of known binding words. It achieves significant improvements in specificity compared to other matrices. This is demonstrated using 95 sets of experimentally determined binding words provided by the TRANSFAC database.

    2006-03-01

    The small heterodimer partner (SHP) is an atypical nuclear receptor lacking the N-terminal ligand-independent activation domain and the DNA binding domain. SHP acts as transcriptional inhibitor of a large set of nuclear receptors, among which ER, AR, CAR, RXR, GR, LXR and ERRgamma. The repression mechanism of SHP involves several actions including competition with coactivators binding on the AF-2 of nuclear receptors and recruitment of transcriptional inhibitors such as EID-1. The investigation of the structure and repression mechanism of SHP is a challenging task for a full understanding of nuclear receptor interaction pathways and functions. So far, mutational analyses in multiple populations identified loss of function mutants of SHP gene involved in mild obesity, increased birth weight and insulin levels. Furthermore, experimental mutagenesis has been exploited to characterize the interactions between SHP and the transcriptional inhibitor EID-1. With the aim of gaining insight into the structural basis of SHP repression mechanism, we modelled SHP and EID-1 structures. Docking experiments were carried out to identify the EID-1 binding surface on SHP structure. The results obtained in this study allow for the first time a unique interpretation of many experimental data available from the published literature. In addition, a fascinating hypothesis raises from the inspection of the proposed SHP structure: the presence of a potential unexpected ligand binding site, supported by recently available experimental data that may represent a breakthrough in the design and development of synthetic modulators of SHP functions.

    Minhas, Fayyaz ul Amir Afsar; Geiss, Brian J; Ben-Hur, Asa

    2014-07-01

    We present a novel partner-specific protein-protein interaction site prediction method called PAIRpred. Unlike most existing machine learning binding site prediction methods, PAIRpred uses information from both proteins in a protein complex to predict pairs of interacting residues from the two proteins. PAIRpred captures sequence and structure information about residue pairs through pairwise kernels that are used for training a support vector machine classifier. As a result, PAIRpred presents a more detailed model of protein binding, and offers state of the art accuracy in predicting binding sites at the protein level as well as inter-protein residue contacts at the complex level. We demonstrate PAIRpred's performance on Docking Benchmark 4.0 and recent CAPRI targets. We present a detailed performance analysis outlining the contribution of different sequence and structure features, together with a comparison to a variety of existing interface prediction techniques. We have also studied the impact of binding-associated conformational change on prediction accuracy and found PAIRpred to be more robust to such structural changes than existing schemes. As an illustration of the potential applications of PAIRpred, we provide a case study in which PAIRpred is used to analyze the nature and specificity of the interface in the interaction of human ISG15 protein with NS1 protein from influenza A virus. Python code for PAIRpred is available at http://combi.cs.colostate.edu/supplements/pairpred/. © 2013 Wiley Periodicals, Inc.

    The chemokine binding protein (CKBP) from orf virus (ORFV) binds with high affinity to chemokines from three classes, C, CC, and CXC, making it unique among poxvirus CKBPs described to date. We present its crystal structure alone and in complex with three CC chemokines, CCL2, CCL3, and CCL7. ORFV CKBP possesses a β-sandwich fold that is electrostatically and sterically complementary to its binding partners. Chemokines bind primarily through interactions involving the N-terminal loop and a hydrophobic recess on the ORFV CKBP β-sheet II surface, and largely polar interactions between the chemokine 20s loop and a negatively charged surface groove located at one end of the CKBP β-sheet II surface. ORFV CKBP interacts with leukocyte receptor and glycosaminoglycan binding sites found on the surface of bound chemokines. SEC-MALLS and chromatographic evidence is presented supporting that ORFV CKBP is a dimer in solution over a broad range of protein concentrations. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The objective of this study is to analyze the association between intimate partner violence against women and maternal educational practice directed to children at the beginning of formal education. This is a cross-sectional study, carried out between 2013 and 2014, with 631 mother/child pairs, registered in the Family Health Strategy of the Health District II of the city of Recife, State of Pernambuco, Brazil. It integrates a prospective cohort study designed to investigate the consequences of exposure to intimate partner violence in relation to the child who was born between 2005 and 2006. The maternal educational practice has been assessed by the Parent-Child Conflict Tactics Scale and the intimate partner violence by a questionnaire adapted from the Multi-Country Study on Women's Health and Domestic Violence of the World Health Organization. Intimate partner violence referred to the last 12 months and was defined by specific acts of psychological, physical, and sexual violence inflicted to women by the partner. The crude and adjusted prevalence ratios were estimated for the association studied, using log-binomial regression. The prevalence of intimate partner violence was 24.4%, and violent maternal educational practice was 93.8%. The use of non-violent discipline was mentioned by 97.6% of the women, coexisting with violent strategies of discipline. Children whose mothers reported intimate partner violence presented a higher chance of suffering psychological aggression (PR = 2.2; 95%CI 1.0-4.7). The violence suffered by the mother interferes in the parental education. The findings show high prevalence of violent maternal educational practice, pointing to the need for interventions that minimize the damage of violence in women and children.

    An X-ray crystal structure showing the binding of purely carboplatin to histidine in a model protein has finally been obtained. This required extensive crystallization trials and various novel crystal structure analyses. Carboplatin is a second-generation platinum anticancer agent used for the treatment of a variety of cancers. Previous X-ray crystallographic studies of carboplatin binding to histidine (in hen egg-white lysozyme; HEWL) showed the partial conversion of carboplatin to cisplatin owing to the high NaCl concentration used in the crystallization conditions. HEWL co-crystallizations with carboplatin in NaBr conditions have now been carried out to confirm whether carboplatin converts to the bromine form and whether this takes place in a similar way to the partial conversion of carboplatin to cisplatin observed previously in NaCl conditions. Here, it is reported that a partial chemical transformation takes place but to a transplatin form. Thus, to attempt to resolve purely carboplatin binding at histidine, this study utilized co-crystallization of HEWL with carboplatin without NaCl to eliminate the partial chemical conversion of carboplatin. Tetragonal HEWL crystals co-crystallized with carboplatin were successfully obtained in four different conditions, each at a different pH value. The structural results obtained show carboplatin bound to either one or both of the N atoms of His15 of HEWL, and this particular variation was dependent on the concentration of anions in the crystallization mixture and the elapsed time, as well as the pH used. The structural details of the bound carboplatin molecule also differed between them. Overall, the most detailed crystal structure showed the majority of the carboplatin atoms bound to the platinum centre; however, the four-carbon ring structure of the cyclobutanedicarboxylate moiety (CBDC) remained elusive. The potential impact of the results for the administration of carboplatin as an anticancer agent are described.

    Adolescent girls with older male main partners are at greater risk for adverse sexual health outcomes than other adolescent girls. One explanation for this finding is that low relationship power occurs with partner age difference. Using a cross-sectional, descriptive design, we investigated the effect of partner age difference between an adolescent girl and her male partner on sexual risk behavior through the mediators of sexual relationship power, and physical intimate partner violence (IPV), and psychological IPV severity. We chose Blanc's framework to guide this study as it depicts the links among demographic, social, economic, relationship, family and community characteristics, and reproductive health outcomes with gender-based relationship power and violence. Urban adolescent girls (N = 155) completed an anonymous computer-assisted self-interview survey to examine partner and relationship factors' effect on consistent condom use. Our sample had an average age of 16.1 years with a mean partner age of 17.8 years. Partners were predominantly African American (75%), non-Hispanic (74%), and low-income (81%); 24% of participants reported consistent condom use in the last 3 months. Descriptive, correlation, and multiple mediation analyses were conducted. Partner age difference was negatively associated with consistent condom use (-.4292, p sexual risk factors within adolescent sexual relationships. Nonetheless, for clinicians and researchers, these findings underscore the heightened risk associated with partner age differences and impact of relationship dynamics on sexual risk behavior.

    In this article, we examine perceptions about the definition of physical intimate partner violence (IPV) in northern India utilizing feminist perspectives as a framework. We interviewed 56 women and 52 men affiliated with a health services nongovernmental organization in the Udaipur district of Rajasthan. We transcribed, coded, and analyzed the interviews utilizing grounded theory. We found that perceptions regarding physical IPV were associated with both structural and ideological patriarchal beliefs and microlevel constructs such as alcohol use. We discovered multiple types of physical IPV in the study region, including rationalized violence (socially condoned violence perpetrated by a husband against his wife), unjustified violence (socially prohibited violence perpetrated by a husband against his wife), and majboori violence (violence perpetrated by a wife against her husband). Our results add to the breadth of research available about IPV in India and create a framework for future research and IPV prevention initiatives.

    Colored fermionic partners of the top quark are well-known signatures of the Composite Higgs scenario and for this reason they have been and will be subject of an intensive experimental study at the LHC. Performing an assessment of the theoretical implications of this experimental effort is the goal of the present paper. We proceed by analyzing a set of simple benchmark models, characterized by simple two-dimensional parameter spaces where the results of the searches are conveniently visualized and their impact quantified. We only draw exclusion contours, in the hypothesis of no signal, but of course our formalism could equally well be used to report discoveries in a theoretically useful format.

    Schneider, Daniel; Harknett, Kristen; McLanahan, Sara

    2016-04-01

    In the United States, the Great Recession was marked by severe negative shocks to labor market conditions. In this study, we combine longitudinal data from the Fragile Families and Child Wellbeing Study with U.S. Bureau of Labor Statistics data on local area unemployment rates to examine the relationship between adverse labor market conditions and mothers' experiences of abusive behavior between 2001 and 2010. Unemployment and economic hardship at the household level were positively related to abusive behavior. Further, rapid increases in the unemployment rate increased men's controlling behavior toward romantic partners even after we adjust for unemployment and economic distress at the household level. We interpret these findings as demonstrating that the uncertainty and anticipatory anxiety that go along with sudden macroeconomic downturns have negative effects on relationship quality, above and beyond the effects of job loss and material hardship.

    2005-01-01

    The emerging care delivery model for Neonatal Intensive Care Units (NICU) is family-focused, developmentally supportive care. The purpose of this study was to explore and describe mothers' experience of becoming a mother while their infants were receiving care in the NICU. A qualitative research design was used. Interviews with 15 mothers whose infants were in a Level III NICU were analyzed using Spradley's domain analysis approach. Mothers developed from outsider to engaged parent along four continua: (1) focus: from NICU to baby; (2) ownership: from their baby to my baby; (3) caregiving: from passive to active; and (4) voice: from silence to advocacy. Mothers entered the continua at different points and moved at different rates toward "engaged parenting." The final stage, partnering, required active participation of nurses. Mothers' development evolved in predictable patterns. The results of this study can be considered in implementation and evaluation plans for NICUs moving to family-focused developmental care.

    High performance houses require a high degree of coordination and have significant interdependencies between various systems in order to perform properly, meet customer expectations, and minimize risks for the builder. Responsibility for the key performance attributes is shared across the project team and can be well coordinated through advanced partnering strategies. For high performance homes, traditional partnerships need to be matured to the next level and be expanded to all members of the project team including trades, suppliers, manufacturers, HERS raters, designers, architects, and building officials as appropriate. This guide is intended for use by all parties associated in the design and construction of high performance homes. It serves as a starting point and features initial tools and resources for teams to collaborate to continually improve the energy efficiency and durability of new houses.

    Full Text Available This study analyzes the relationship between partner violence, depression and maternal self-efficacy in migrant women. It is thought that this type of violence brings about sinking morale and a hindrance for their development as mothers. It is a quantitative study of an explanatory correlational type, worked with 40 immigrant women with a residence of two to 25 years, with at least one reported episode of violation and at least one son in preschool. Three instruments were employed: “The Parental Involvement and Efficacy”, “The Survey-Depression Scale” and“The Revised Conflict Tactic Scale”. The results showed important relationships between the variables, namely, the more violence women suffer, the greater the depression is, and the greater the depression is, the lesser the maternal self-efficacy becomes.

    The Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) opposes laws and other policies that require nurses to report the results of screening for intimate partner violence (IPV) to law enforcement or other regulatory agencies without the consent of the woman who experiences the IPV. Nurses and other health care professionals, however, should become familiar with laws on mandatory reporting in their states and comply as applicable. Women should be universally screened for IPV in private, safe settings where health care is provided. Nurses are ideally positioned to screen for IPV for the purpose of initiating a referral for services and support when applicable. To protect the woman's safety, AWHONN supports policies that require a woman's consent before reporting occurs.

    2014-01-01

    Full Text Available This theoretical study reviews two of the most cited profiles of intimate partner batterers in the scientific literature, paying special attention to the most notable differences between them, as well as to their common criteria. The study also discusses one of the longest standing controversies in various research studies, including the particular overview with respect to Spain: it being the constant yet erroneous reference to the equivalence of psychopathy and antisocial personality disorder. Similarly, special attention is paid to the implications of considering intimate partner batterers as having either a psychopathological or psychopathic profile, while also stressing the specific role played by psychopathy in the intimate partner batterer and, concerning psychopathic intimate partner batterers, such aspects as their specific motives for perpetrating intimate partner violence and the evaluation instruments of this particular profile. Finally, a series of future directives for research concerning psychopathic intimate partner batterers are also pointed out.

    Although intimate partner aggression crosses social class boundaries, education and income are important predictors. Yet given that emerging adulthood is a transitional period, completed education and employment, as single measures, are not ideal indicators of socioeconomic status for young people. We examined associations between self-reports of gainful activity, defined as enrollment in school or full-time employment, and intimate partner aggression among young adults in dating, cohabiting, or married relationships ( N =648). Both men and women's participation in gainful activity was negatively associated with aggression. We found that when neither partner was gainfully active, individuals reported higher frequency of physical aggression. In cases of gainful activity asymmetry, the gender of the gainfully active partner did not predict intimate partner aggression. Additionally, we found no evidence that the association between gainful activity and frequency of intimate partner aggression differed by union type.

    2008-01-01

    We investigated correlates of partner abuse in male same-sex relationships in a randomly selected community sample (N = 186). We included factors associated with abuse in heterosexual relationships, as well as factors of relevance to gay relationships. We assessed perpetration and receipt of partner abuse to examine whether variables were associated independently with abuse perpetration and/or receipt. Correlates of same-sex partner abuse were largely parallel to established correlates of heterosexual abuse. Income, education, and attachment orientation were associated with bidirectional partner abuse, and family violence and substance use were uniquely associated with victimization. Further, there were factors unique to same-sex partner abuse; HIV status and public outness were associated with bidirectional partner abuse, and internalized homophobia was uniquely associated with abuse perpetration.

    Current rates of intimate partner homicide of females are approximately 4 to 5 times the rate for male victims, although the rates for both have decreased during the past 25 years. The major risk factor for intimate partner homicide, no matter if a female or male partner is killed, is prior domestic violence. This review presents and critiques the evidence supporting the other major risk factors for intimate partner homicide in general, and for intimate partner homicide of women (femicide) in particular, namely guns, estrangement, stepchild in the home, forced sex, threats to kill, and nonfatal strangulation (choking). The demographic risk factors are also examined and the related phenomena of pregnancy-related homicide, attempted femicide, and intimate partner homicide-suicide.

  4. IGF binding proteins.

    2017-12-18

    Insulin-like growth factor binding proteins (IGFBPs) 1-6 bind IGFs but not insulin with high affinity. They were initially identified as serum carriers and passive inhibitors of IGF actions. However, subsequent studies showed that, although IGFBPs inhibit IGF actions in many circumstances, they may also potentiate these actions. IGFBPs are widely expressed in most tissues, and they are flexible endocrine and autocrine/paracrine regulators of IGF activity, which is essential for this important physiological system. More recently, individual IGFBPs have been shown to have IGF-independent actions. Mechanisms underlying these actions include (i) interaction with non-IGF proteins in compartments including the extracellular space and matrix, the cell surface and intracellularly; (ii) interaction with and modulation of other growth factor pathways including EGF, TGF- and VEGF; and (iii) direct or indirect transcriptional effects following nuclear entry of IGFBPs. Through these IGF-dependent and IGF-independent actions, IGFBPs modulate essential cellular processes including proliferation, survival, migration, senescence, autophagy and angiogenesis. They have been implicated in a range of disorders including malignant, metabolic, neurological and immune diseases. A more complete understanding of their cellular roles may lead to the development of novel IGFBP-based therapeutic opportunities.

    2011-07-01

    In randomized controlled trials of expedited partner therapy (EPT), among patients in the EPT arm, the proportion of partners believed to have taken the medication ranged from 56% to 85%. Little is known about the content of successful and unsuccessful EPT negotiations between patients and their partners. The aim of this study was to describe how patients made decisions about EPT and what they did with the EPT medication packs dispensed to them. We performed a qualitative study at the Baltimore City Health Department sexually transmitted disease clinics, which instituted an EPT pilot program in 2007. In-depth interviews were conducted with 31 patients, 1 week to 3 months after they had accepted EPT to bring to their partners. Taped interviews were transcribed verbatim and coded using ATLAS.ti 6 qualitative software. Codes were further combined into more comprehensive themes that were mapped onto the study's main aim. Participants were innovative about how to get medication to their partners and indicated a deep sense of concern and responsibility for their partners' health. On the other hand, participants reported of being anxious about the interaction and sometimes felt that they lacked the words to talk with their partners about EPT. Some participants used EPT in unexpected ways, such as giving it to people other than their sex partners or taking it themselves. Enhancing the counseling that accompanies EPT may improve patients' success in delivering it to their partners.

    Social support research suggests romantic partners could play a vital role in the success of individuals' weight management (WM) efforts, but contradictory findings from previous research have impeded our understanding of how romantic partners influence weight management goal attainment. Employing a confirmation perspective, overweight participants (body mass index [BMI] greater than 25) who were actively trying to manage their weight (N = 53) were asked to respond to daily questionnaires for a period of 2 weeks regarding their interactions with their romantic partner. Diet, exercise, and general weight management goal accomplishment were assessed. HLM was employed to assess the independent and interactive effects of partner acceptance and challenge on each of these goals. Findings suggest that perceiving high levels of both acceptance and challenge from partners was associated with more general WM and diet goal accomplishment. However, greater attainment of exercise goals was associated with only challenge. Fluctuations in partner acceptance and challenge were also examined to determine whether consistency in confirmation behaviors was associated with WM goals. Hierarchical regressions revealed that fluctuations in acceptance, but not challenge, were linked with goal attainment. Specifically, fluctuations in acceptance were helpful for those whose partners were perceived to exhibit lower levels of acceptance, but fluctuations were detrimental for those whose partners exhibited greater acceptance. Implications for communication among couples in which one partner is attempting to lose weight are discussed.

    The study aimed to test if there was an association between prevalent bacterial vaginosis (BV) and women reporting that their partner had other partners at the same time (partner concurrency). This association has not been assessed in a longitudinal cohort. The Longitudinal Study of Vaginal Flora recruited a cohort of 3620 non-pregnant women aged 15-44 years who presented for routine primary healthcare at 12 clinics in Birmingham, Alabama. Behavioural questionnaires and vaginal smears were obtained quarterly for a year and BV was defined by a Nugent score 7 or higher as well as Amsel criteria. Mixed effects logistic regression was used to assess the relationship between prevalent BV and reporting that one's partner had other partners in the preceding 3-6 months time interval. Nugent score prevalent BV was associated with both reporting that one's partner definitely (adjusted OR (aOR) 1.5; 95% CI 1.2 to 1.8) and possibly (aOR 1.5; 95% CI 1.2 to 1.8) engaged in partner concurrency in the preceding 3-6 months time period. Prevalent BV diagnosed by Amsel criteria was similar. A diagnosis of prevalent BV was associated with reporting that one's partner possibly or definitely engaged in partner concurrency.

  14. Visualization of coupled protein folding and binding in bacteria and purification of the heterodimeric complex

    Wang, Haoyong; Chong, Shaorong

    2003-01-01

    During overexpression of recombinant proteins in Escherichia coli, misfolded proteins often aggregate and form inclusion bodies. If an aggregation-prone recombinant protein is fused upstream (as an N-terminal fusion) to GFP, aggregation of the recombinant protein domain also leads to misfolding of the downstream GFP domain, resulting in a decrease or loss of fluorescence. We investigated whether the GFP domain could fold correctly if aggregation of the upstream protein domain was prevented in vivo by a coupled protein folding and binding interaction. Such interaction has been previously shown to occur between the E. coli integration host factors and , and between the domains of the general transcriptional coactivator cAMP response element binding protein (CREB)-binding protein and the activator for thyroid hormone and retinoid receptors. In this study, fusion of integration host factor or the CREB-binding protein domain upstream to GFP resulted in aggregation of the fusion protein. Coexpression of their respective partners, on the other hand, allowed soluble expression of the fusion protein and a dramatic increase in fluorescence. The study demonstrated that coupled protein folding and binding could be correlated to GFP fluorescence. A modified miniintein containing an affinity tag was inserted between the upstream protein domain and GFP to allow rapid purification and identification of the heterodimeric complex. The GFP coexpression fusion system may be used to identify novel protein-protein interactions that involve coupled folding and binding or protein partners that can solubilize aggregation-prone recombinant proteins.

  15. Achieving peptide binding specificity and promiscuity by loops: case of the forkhead-associated domain.

    Science.gov (United States)

    Huang, Yu-Ming M; Chang, Chia-En A

    2014-01-01

    The regulation of a series of cellular events requires specific protein-protein interactions, which are usually mediated by modular domains to precisely select a particular sequence from diverse partners. However, most signaling domains can bind to more than one peptide sequence. How do proteins create promiscuity from precision? Moreover, these complex interactions typically occur at the interface of a well-defined secondary structure, α helix and β sheet. However, the molecular recognition primarily controlled by loop architecture is not fully understood. To gain a deep understanding of binding selectivity and promiscuity by the conformation of loops, we chose the forkhead-associated (FHA) domain as our model system. The domain can bind to diverse peptides via various loops but only interact with sequences containing phosphothreonine (pThr). We applied molecular dynamics (MD) simulations for multiple free and bound FHA domains to study the changes in conformations and dynamics. Generally, FHA domains share a similar folding structure whereby the backbone holds the overall geometry and the variety of sidechain atoms of multiple loops creates a binding surface to target a specific partner. FHA domains determine the specificity of pThr by well-organized binding loops, which are rigid to define a phospho recognition site. The broad range of peptide recognition can be attributed to different arrangements of the loop interaction network. The moderate flexibility of the loop conformation can help access or exclude binding partners. Our work provides insights into molecular recognition in terms of binding specificity and promiscuity and helpful clues for further peptide design.

  17. Miz-1 activates gene expression via a novel consensus DNA binding motif.

    Directory of Open Access Journals (Sweden)

    Bonnie L Barrilleaux

    Full Text Available The transcription factor Miz-1 can either activate or repress gene expression in concert with binding partners including the Myc oncoprotein. The genomic binding of Miz-1 includes both core promoters and more distal sites, but the preferred DNA binding motif of Miz-1 has been unclear. We used a high-throughput in vitro technique, Bind-n-Seq, to identify two Miz-1 consensus DNA binding motif sequences--ATCGGTAATC and ATCGAT (Mizm1 and Mizm2--bound by full-length Miz-1 and its zinc finger domain, respectively. We validated these sequences directly as high affinity Miz-1 binding motifs. Competition assays using mutant probes indicated that the binding affinity of Miz-1 for Mizm1 and Mizm2 is highly sequence-specific. Miz-1 strongly activates gene expression through the motifs in a Myc-independent manner. MEME-ChIP analysis of Miz-1 ChIP-seq data in two different cell types reveals a long motif with a central core sequence highly similar to the Mizm1 motif identified by Bind-n-Seq, validating the in vivo relevance of the findings. Miz-1 ChIP-seq peaks containing the long motif are predominantly located outside of proximal promoter regions, in contrast to peaks without the motif, which are highly concentrated within 1.5 kb of the nearest transcription start site. Overall, our results indicate that Miz-1 may be directed in vivo to the novel motif sequences we have identified, where it can recruit its specific binding partners to control gene expression and ultimately regulate cell fate.

  18. Binding mechanisms of intrinsically disordered proteins: theory, simulation, and experiment

    Directory of Open Access Journals (Sweden)

    Luca Mollica

    2016-09-01

    Full Text Available In recent years, protein science has been revolutionized by the discovery of intrinsically disordered proteins (IDPs. In contrast to the classical paradigm that a given protein sequence corresponds to a defined structure and an associated function, we now know that proteins can be functional in the absence of a stable three-dimensional structure. In many cases, disordered proteins or protein regions become structured, at least locally, upon interacting with their physiological partners. Many, sometimes conflicting, hypotheses have been put forward regarding the interaction mechanisms of IDPs and the potential advantages of disorder for protein-protein interactions. Whether disorder may increase, as proposed e.g. in the fly-casting hypothesis, or decrease binding rates, increase or decrease binding specificity, or what role pre-formed structure might play in interactions involving IDPs (conformational selection vs. induced fit, are subjects of intense debate. Experimentally, these questions remain difficult to address. Here, we review experimental studies of binding mechanisms of IDPs using NMR spectroscopy and transient kinetic techniques, as well as the underlying theoretical concepts and numerical methods that can be applied to describe these interactions at the atomic level. The available literature suggests that the kinetic and thermodynamic parameters characterizing interactions involving IDPs can vary widely and that there may be no single common mechanism that can explain the different binding modes observed experimentally. Rather, disordered proteins appear to make combined use of features such as pre-formed structure and flexibility, depending on the individual system and the functional context.

    2012-03-01

    Full Text Available Insulin-like growth factor binding proteins (IGFBP-1 to -6 bind insulin-like growth factors-I and -II (IGF-I and IGF-II with high affinity. These binding proteins maintain IGFs in the circulation and direct them to target tissues, where they promote cell growth, proliferation, differentiation and survival via the type 1 IGF receptor (IGF-1R. IGFBPs also interact with many other molecules, which not only influence their modulation of IGF action but also mediate IGF-independent activities that influence processes such as cell migration and apoptosis by influencing gene transcription.IGFBPs-1 to -6 are structurally similar proteins consisting of three distinct domains, N-terminal, Linker and C-terminal. There have been major advances in our understanding of IGFBP structure in the last decade and a half. While there is still no structure of an intact IGFBP to date, several structures of individual N- and C-domains have been solved. The structure of a complex of N-BP-4:IGF-I:C-BP-4 has also been solved, providing a detailed picture of the structural features of the IGF binding site and the mechanism of binding. Structural studies have also identified features important for interaction with extracellular matrix components and integrins. This review summarises structural studies reported so far and highlights features important for binding not only IGF but also other partners. It also highlights future directions in which structural studies will add to our knowledge of the role played by the IGFBP family in normal growth and development, as well as in disease.

  19. Protein Interacting with C Kinase 1 (PICK1) Reduces Reinsertion Rates of Interaction Partners Sorted to Rab11-dependent Slow Recycling Pathway*

    Madsen, Kenneth L.; Thorsen, Thor S.; Rahbek-Clemmensen, Troels; Eriksen, Jacob; Gether, Ulrik

    2012-01-01

    The scaffolding protein PICK1 (protein interacting with C kinase 1) contains an N-terminal PSD-95/Discs large/ZO-1 (PDZ) domain and a central lipid-binding Bin/amphiphysin/Rvs (BAR) domain. PICK1 is thought to regulate trafficking of its PDZ binding partners but different and even opposing functions have been suggested. Here, we apply ELISA-based assays and confocal microscopy in HEK293 cells with inducible PICK1 expression to assess in an isolated system the ability of PICK1 to regulate trafficking of natural and engineered PDZ binding partners. The dopamine transporter (DAT), which primarily sorts to degradation upon internalization, did not form perinuclear clusters with PICK1, and PICK1 did not affect DAT internalization/recycling. However, transfer of the PICK1-binding DAT C terminus to the β2-adrenergic receptor, which sorts to recycling upon internalization, led to formation of PICK1 co-clusters in Rab11-positive compartments. Furthermore, PICK1 inhibited Rab11-mediated recycling of the receptor in a BAR and PDZ domain-dependent manner. In contrast, transfer of the DAT C terminus to the δ-opioid receptor, which sorts to degradation, did not result in PICK1 co-clusters or any change in internalization/recycling. Further support for a role of PICK1 determined by its PDZ cargo was obtained for the PICK1 interaction partner prolactin-releasing peptide receptor (GPR10). GPR10 co-localized with Rab11 and clustered with PICK1 upon constitutive internalization but co-localized with the late endosomal marker Rab7 and did not cluster with PICK1 upon agonist-induced internalization. Our data suggest a selective role of PICK1 in clustering and reducing the recycling rates of PDZ domain binding partners sorted to the Rab11-dependent recycling pathway. PMID:22303009

    1991-05-01

    Just expecting more from your supplier is not what partnership is about. We have had the experience where the quality improvement and partnership banner has been waved but the tone and spirit of the meeting did not encourage or support a joint quality improvement effort. Benefits will not be achieved until the wall truly begins to come apart and the relationship is built on mutual respect and trust. Data collection and open answers to questions often reveal embarrassing errors and obvious needs for improvements. As stated before, blame and finger-pointing must be replaced with a mutual commitment to asking and answering the question, "How can we improve?" As Dr. W. Edwards Deming has stated, "End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move toward a single supplier for any one item on a long-term relationship of loyalty and trust." The structured approach of a quality improvement process and the application of quality methods and techniques has proven useful in removing emotion and helping the team focus on the process rather than the people and the issues involved. Quality improvement methods are focused on achieving both customer and supplier goals--customer satisfaction, employee satisfaction, and operational efficiency and effectiveness. Our experience with Partners in Quality as well as our experience with the quality leadership process supports a recent quote in the Harvard Business Review: "Quality is not just a slogan...(it is) the most profitable way to run a business."

  1. Trajectories of Intimate Partner Violence Victimization

    2012-08-01

    Full Text Available Introduction: The purposes of this study were to assess the extent to which latent trajectories of female intimate partner violence (IPV victimization exist; and, if so, use negative childhood experiences to predict trajectory membership.Methods: We collected data from 1,575 women at 5 time-points regarding experiences during adolescence and their 4 years of college. We used latent class growth analysis to fit a series of personcentered, longitudinal models ranging from 1 to 5 trajectories. Once the best-fitting model was selected, we used negative childhood experience variables—sexual abuse, physical abuse, and witnessing domestic violence—to predict most-likely trajectory membership via multinomial logistic regression.Results: A 5-trajectory model best fit the data both statistically and in terms of interpretability. The trajectories across time were interpreted as low or no IPV, low to moderate IPV, moderate to low IPV, high to moderate IPV, and high and increasing IPV, respectively. Negative childhood experiences differentiated trajectory membership, somewhat, with childhood sexual abuse as a consistent predictor of membership in elevated IPV trajectories.Conclusion: Our analyses show how IPV risk changes over time and in different ways. These differential patterns of IPV suggest the need for prevention strategies tailored for women that consider victimization experiences in childhood and early adulthood.

  2. Building Partner Cooperation between Teachers and Parents

    Full Text Available This paper presents the goals of teacher-parent cooperation, various potential models for establishing mutual cooperation, and the conditions required to achieve quality interactive cooperation. The partnership model is highlighted as an optimal model of interactive cooperation between teachers and parents, as it includes the distribution of expertise and control with the purpose of ensuring optimal education for children. It enables the creation of an interactive working relationship in which all of those involved are respected and recognised in their efforts to achieve common goals.The second part presents the findings of an empirical study carried out on a representative sample of Slovene primary schools. Teachers (N = 467 and parents (N = 1,690 were asked to express their pinions about the need for mutual cooperation, their view of each other when fulfilling their respective roles, and where they perceive the main obstacles to mutual cooperation. It became evident that teachers and parents have doubts about each other’s competence. This does not form a solid base on which to establish and build the necessary partner relationship, and along with it mutual cooperation. Yet both groups to a large extent agree that teacher-parent cooperation is both necessary and useful. This gives rise to the question as to how to ensure that schools adopt policies promotingopportunities for better understanding, for building quality mutualrelations and for parents to become more actively involved.

    1999-01-01

    An overview is included of experience and working relationships of the author that were established with a First Nations people. Terracon first had the opportunity of cooperating and working with a First Nations company in 1966. This relationship originated in conjunction with the reclamation activities at an oil sand operations. This working relationship developed as part of translating landscape plans into final landscapes at the oil sand mine. The work required good team efforts with employees of the Aboriginal company. The initial contacts and working relationships were reasonably satisfactory but these tasks did not bring the author and his partners into direct contact with senior First Nation staff and management. More importantly, the contacts and working relationships made the author realize that there may be opportunities to form strategic alliances and/or joint ventures with Aboriginal companies, particularly in light of the oil sand operator's commitment to employ Aboriginals and Aboriginal owned companies. Several other companies approached the Fort McKay Group, but were unsuccessful. Terracon was successful because it: identified and dealt with the decision makers, had patience and persistence with a First Nation's democratic process, already developed a personal relationship and trust with the band, and started with several verbal agreements, leading to written contracts and then to the current partnership, Terracon-McKay Ltd

    Intimate partner violence is one of the most pervasive global public health problems affecting women. It results in untold costs to the healthcare system and is positively linked to eight out of ten leading indicators for Healthy People 2010. Intimate partner violence also is one of the factors associated with adverse childhood experiences that result in negative healthcare behaviours. Intimate partner violence has been the subject of film, made for television movies and music videos. The use of film as an innovative tool to teach about common health and mental health disorders is well-documented. Film also has been used as an adjunctive therapeutic tool in counselling. This paper will provide an overview of intimate partner violence, its portrayal in popular film and ways in which educators may use film to teach intimate partner violence-related topics.

    This study examines secondary traumatization among 708 partners and 332 parents of Dutch peacekeepers (i.e., personnel who participated in military actions implemented by international organizations such as the United Nations). Partners or parents of peacekeepers with 4 levels of posttraumatic stress symptoms were compared on posttraumatic stress, health problems, the quality of the marital relationship, and social support. In comparison with partners of peacekeepers without posttraumatic stress disorder (PTSD) symptoms, partners of peacekeepers with PTSD symptoms reported more sleeping and somatic problems, reported more negative social support, and judged the marital relationship as less favorable. No significant differences were found for parents. Thus, peacekeepers' stress reactions were related to various problems of their partners. A systemic approach to the treatment of persons with PTSD appears appropriate. 2005 APA, all rights reserved

    Using data collected from people with at least one brother and one sister, and consistent with an evolutionary perspective, we find that older men and women (a) are more upset by a brother's partner's sexual infidelity than by her emotional infidelity and (b) are more upset by a sister's partner's emotional infidelity than by his sexual infidelity. There were no effects of participant sex or sex of in-law on upset over a sibling's partner's infidelities, but there was an effect of participant sex on reports of upset over one's own partner's infidelities. The results suggest that the key variable among older participants is the sex of the sibling or, correspondingly, the sex of the sibling's partner, as predicted from an evolutionary analysis of reproductive costs, and not the sex of the participant, as predicted from a socialization perspective. Discussion offers directions for future work on jealousy.

    Women Veterans are at increased risk of both housing instability and intimate partner violence compared with their non-Veteran counterparts. The objectives of the present study were (1) to assess the relationship between women Veterans' experience of intimate partner violence and various indicators of housing instability, and (2) to assess what correlates help to explain experiences of housing instability among women Veterans who experienced past-year intimate partner violence. Data were collected from U.S. Department of Veterans Affairs electronic medical records for 8,427 women Veterans who were screened for past-year intimate partner violence between April 2014 and April 2016 at 13 Veterans Affairs' facilities. Logistic regressions performed during 2017 assessed the relationship between past-year intimate partner violence and housing instability. A total of 8.4% of the sample screened positive for intimate partner violence and 11.3% for housing instability. Controlling for age and race, a positive intimate partner violence screen increased odds of housing instability by a factor of 3. Women Veterans with past-year intimate partner violence were more likely to have an indicator of housing instability if they identified as African American, had screened positive for military sexual trauma, or had a substance use disorder; receiving compensation for a disability incurred during military service and being married were protective. For women Veterans, intimate partner violence interventions should assess for both physical and psychological housing needs, and housing interventions should coordinate with intimate partner violence programs to address common barriers to resources.

    Using a large prospective cohort of women age 40 or younger diagnosed with breast cancer, we examined the relationship between perceived partner support and anxiety. Six hundred seventy-five young women with breast cancer Stages I-III, median age 36, completed a self-report baseline questionnaire. Perceived partner support was assessed using items extracted from the marital subscale of the Cancer Rehabilitation Evaluation System; generalized social support was assessed with the Medical Outcomes Study-Social Support Survey. Anxiety was measured using the anxiety subscale of the Hospital Anxiety and Depression Scale. Multivariable logistic regression analyses evaluated the association between partner support, other sociodemographic factors, and anxiety. Mean age at diagnosis was 35.4 years. Fourteen percent of the women were not partnered, and among those who were partnered or in a significant relationship, 20% were categorized as unsupported. In univariate and multivariable analysis adjusting for sociodemographic factors, women in an unsupported-partnered relationship had higher odds of anxiety symptoms compared with women in a supported-partnered relationship. Young age and being financially insecure were also both independently associated with anxiety. Our findings suggest that partner support may play a key role in a young woman's adjustment to a serious stressor such as breast cancer. In addition, younger age increases vulnerability to anxiety as does struggling with finances. Because supportive efforts of a partner have potential to protect against the impact of stress, interventions to enhance partner support and reduce anxiety might be beneficial to address challenges experienced as a couple in this setting.

  9. Mucin 1 (MUC1 is a novel partner for MAL2 in breast carcinoma cells

    Directory of Open Access Journals (Sweden)

    McGuckin Michael A

    2009-01-01

    Full Text Available Abstract Background The MAL2 gene, encoding a four-transmembrane protein of the MAL family, is amplified and overexpressed in breast and other cancers, yet the significance of this is unknown. MAL-like proteins have trafficking functions, but their molecular roles are largely obscure, partly due to a lack of known binding partners. Methods Yeast two-hybrid screening of a breast carcinoma cDNA expression library was performed using a full-length MAL2 bait, and subsequent deletion mapping experiments were performed. MAL2 interactions were confirmed by co-immunoprecipitation analyses and confocal microscopy was employed to compare protein sub-cellular distributions. Sucrose density gradient centrifugation of membranes extracted in cold Triton X-100 was employed to compare protein distributions between Triton X-100-soluble and -insoluble fractions. Results The tumor-associated protein mucin 1 (MUC1 was identified as a potential MAL2 partner, with MAL2/MUC1 interactions being confirmed in myc-tagged MAL2-expressing MCF-10A cells using co-immunoprecipitation assays. Deletion mapping experiments demonstrated a requirement for the first MAL2 transmembrane domain for MUC1 binding, whereas the MAL2 N-terminal domain was required to bind D52-like proteins. Confocal microscopy identified cytoplasmic co-localisation of MUC1 and MAL2 in breast cell lines, and centrifugation of cell lysates to equilibrium in sucrose density gradients demonstrated that MAL2 and MUC1 proteins were co-distributed between Triton X-100-soluble and -insoluble fractions. However co-immunoprecipitation analyses detected MAL2/MUC1 interactions in Triton X-100-soluble fractions only. Myc-MAL2 expression in MCF-10A cells was associated with both increased MUC1 detection within Triton X-100-soluble and -insoluble fractions, and increased MUC1 detection at the cell surface. Conclusion These results identify MUC1 as a novel MAL2 partner, and suggest a role for MAL2 in regulating MUC1

    Full Text Available The article is devoted to the classification of bindings of the 1-19th centuries with a unique and untypical book binding decoration technique (encaustic, tempera and oil paintings. Analysis of design features, materials and techniques of art decoration made it possible to identify them as a separate type - pictorial bindings and divide them into four groups. The first group consists of Coptic bindings, decorated with icon-painting images in encaustic technique. The second group is made up of leather Western bindings of the 13-14th centuries, which have the decoration and technique of ornamentation close to iconography. The third group involves parchment bindings, ornamentation technique of which is closer to the miniature. The last group comprises bindings of East Slavic origin of the 15-19th centuries, decorated with icon-painting pictures made in the technique of tempera or oil painting. The proposed classification requires further basic research as several specific kinds of bindings have not yet been investigated

    Universal screening for maternal depression and assessment of psychosocial risks has been integrated into the routine perinatal care provided in many Australian hospitals, but to date, partners/fathers have been largely excluded from the process. This study explored the ways in which clinicians in health service settings include partners who attend antenatal and postnatal visits with women. Qualitative data were collected using observations (n = 54), interviews (n = 60), and discussion groups (n = 7) with midwives and child and family health nurses who conducted the appointments. Transcripts from observations, interviews, and discussion groups underwent qualitative analysis, and key themes were identified. Results showed partners to have little or no involvement in psychosocial assessment and depression screening. Thematic analysis revealed four key themes: negotiating partner exclusion, partial inclusion, women's business or a couple concern? and they know anyway. Partner involvement appeared to be challenged particularly by mandatory interpersonal violence screening, which, according to health service policy, is to be conducted confidentially. Overall, results highlighted partner involvement in perinatal depression screening and psychosocial assessment processes and identified some of the benefits such as partner disclosure, but also the challenges and complexities of inclusion of partners. Clinical implications and directions for further education and research are discussed. © 2016 Michigan Association for Infant Mental Health.

    Specific interactions between proteins and their binding partners are fundamental to life processes. The ability to detect protein complexes, and map their sites of binding, is crucial to understanding basic biology at the molecular level. Methods that employ sensitive analytical techniques such as mass spectrometry have the potential to provide valuable insights with very little material and on short time scales. Here we present a differential protein footprinting technique employing an efficient photo-activated probe for use with mass spectrometry. Using this methodology the location of a carbohydrate substrate was accurately mapped to the binding cleft of lysozyme, and in a more complex example, the interactions between a 100 kDa, multi-domain deubiquitinating enzyme, USP5 and a diubiquitin substrate were located to different functional domains. The much improved properties of this probe make carbene footprinting a viable method for rapid and accurate identification of protein binding sites utilizing benign, near-UV photoactivation.

    Full Text Available Abstract Background Genital chlamydia is the most commonly notified sexually transmissible infection (STI in Australia and worldwide and can have serious reproductive health outcomes. Partner notification, testing and treatment are important facets of chlamydia control. Traditional methods of partner notification are not reaching enough partners to effectively control transmission of chlamydia. Patient-delivered partner therapy (PDPT has been shown to improve the treatment of sexual partners. In Australia, General Practitioners (GPs are responsible for the bulk of chlamydia testing, diagnosis, treatment and follow up. This study aimed to determine the views and practices of Australian general practitioners (GPs in relation to partner notification and PDPT for chlamydia and explored GPs' perceptions of their patients' barriers to notifying partners of a chlamydia diagnosis. Methods In-depth, semi-structured telephone interviews were conducted with 40 general practitioners (GPs from rural, regional and urban Australia from November 2006 to March 2007. Topics covered: GPs' current practice and views about partner notification, perceived barriers and useful supports, previous use of and views regarding PDPT. Transcripts were imported into NVivo7 and subjected to thematic analysis. Data saturation was reached after 32 interviews had been completed. Results Perceived barriers to patients telling partners (patient referral included: stigma; age and cultural background; casual or long-term relationship, ongoing relationship or not. Barriers to GPs undertaking partner notification (provider referral included: lack of time and staff; lack of contact details; uncertainty about the legality of contacting partners and whether this constitutes breach of patient confidentiality; and feeling both personally uncomfortable and inadequately trained to contact someone who is not their patient. GPs were divided on the use of PDPT - many felt concerned that it is not

    To describe the prevalence of intimate partner violence (IPV) in Spain in the last year and at some point during the lifetime, to determine health status in women according to whether they had experienced IPV or not, and to analyze the individual variables associated with IPV in Spain. A cross-sectional study was performed of the database, Macrosurvey on Gender Violence in Spain 2011. This database includes data on 7,898 women older than 18 years old. The dependent variables were IPV-last year, IPV-ever in life. Covariates consisted of sociodemographic characteristics, socioeconomic status, maternal experience of IPV, social support, and self-care. The measure of association used was the OR with its 95% confidence interval (95% CI). A total of 3.6% of women had experienced IPV-last year and 12.2% ever in life. Female victims of IPV had poorer health than women who had not experienced IPV. Immigrant women living in Spain for 6 years or more were more likely to experience IPV-ever in life than Spanish women [OR (95% CI): 1.95 (1.50, 2.53)]. An interaction was found between nationality and the existence of children under 18 years old. Among women with children under 18 years old, immigrant women were more likely to experience IPV-last year than Spanish women [OR (95% CI): 1.99 (1.25, 3.17)]. Other variables associated with IPV were age, low socioeconomic status, low social support and having a mother who had experienced IPV. In Spain, some women have a higher probability of experiencing IPV. The variables associated with greater vulnerability to IPV should be taken into account when implementing measures to prevent or alleviate IPV. Copyright © 2013 SESPAS. Published by Elsevier Espana.

    Full Text Available Objectives: This study assessed intimate partner violence (IPV and alcohol use in an urban population in Pune, India. The prevalence of IPV and alcohol use was assessed along with the correlation of IPV with alcohol and other variables. Materials and Methods: The study was cross-sectional, questionnaire-based. The materials used were the hurt insult threaten scream (HITS scale, the alcohol use disorders identification test, and a brief psychosocial questionnaire. Systematic random sampling was done on the target population. Regression analysis of various factors in relation to HITS score was done. Results: Sample size (n was 318 individuals. Prevalence of IPV was found to be 16% and the victims were mostly women. Prevalence of alcohol use was 44%, of which 8.9% were harmful users. No female subjects consumed alcohol, but 94% were aware of their husband's alcohol consumption. No significant correlation was found between IPV and education (P = 0.220 or income of women (P = 0.250. Alcohol consumption by males was a significant risk factor for women experiencing IPV (σ = +0.524; P< 0.001. Regression analysis also revealed that increasing marital age (P = 0.019 and financial support from in-laws (P = 0.040 were significantly protective. Conclusion: IPV prevalence was less than the national average for India, but the majority of victims was women. The most common type of IPV was verbal. Alcohol use prevalence was higher than the national average, but harmful use was lower. Alcohol use is a significant risk factor for IPV. Education and income of women were not significantly protective against IPV but increased age at marriage and support from in-laws were.

  19. Partnering with stakeholders in radioactive waste management

    Site selection for radioactive waste management (RWM) facilities draws considerable attention from implementers, government bodies, local communities and the public at large. Facility siting processes have generally tended to be marred by conflicts, disagreements and delays. In response, efforts have been made to shift from a more traditional 'decide, announce and defend' model to one of 'engage, interact and co-operate'. The essence of the new approach is co-operation or partnership between the implementer and the affected communities, involving dialogue between experts and citizens, mutual learning and public participation in the decision-making process. National ministries and authorities have also been called to and do play a more visible role. The intensity and degree of partnering can vary from country to country and in different phases of project development. Important changes have taken place in citizen participation in radioactive waste management over the past decade. These changes can be summarised as follows: - shift from information and consultation towards partnership, i.e. from token involvement to citizen influence and power; - shift from a passive to an active role of local communities: from resigned acceptance to collaboration, volunteering and veto; - development of a great variety of administrative formats for collaboration; - recognition of the need for, and legitimacy of, community empowerment measures and socio-economic benefits; - emergence of new ideals and bases for collaboration including mutual learning, adding values to the host community/region and sustainable development. Involving local actors in the design of the facility and community benefits are likely to result in solutions that will add value to the host region. In all cases, social capital is augmented as local stakeholders develop new skills and increase their knowledge about the interests and ideals of their community. Implementers and other institutional players also

    The mental and physical health consequences of intimate partner violence (IPV) have been well established, yet little is known about the impact of violence on a woman's ability to obtain and maintain housing. This cross-sectional study examines the relationship between recent IPV and housing instability among a representative sample of California women. It is expected that women who have experienced IPV will be at increased risk for housing instability as evidenced by: (1) late rent or mortgage, (2) frequent moves because of difficulty obtaining affordable housing, and/or (3) without their own housing. Data were taken from the 2003 California Women's Health Survey, a population-based, random-digit-dial, annual probability survey of adult California women (N=3619). Logistic regressions were used to predict housing instability in the past 12 months, adjusting for the following covariates; age, race/ethnicity, education, poverty status, marital status, children in the household, and past year IPV. In the multivariate model, age, race/ethnicity, marital status, poverty, and IPV were significant predictors of housing instability. After adjusting for all covariates, women who experienced IPV in the last year had almost four times the odds of reporting housing instability than women who did not experience IPV (adjusted odds ratio=3.98, 95% confidence interval: 2.94-5.39). This study found that IPV was associated with housing instability among California women. Future prospective studies are needed to learn more about the nature and direction of the relationship between IPV and housing instability and the possible associated negative health consequences.

    2005-10-01

    This study examined partner violence and perceived family functioning among a sample of 298 male veterans and their female partners. Partner violent men were higher than partner violent women on measures of partner violence severity, although differences did not reach statistical significance. Among couples experiencing unidirectional violence, female victims of partner violence reported significantly poorer family functioning than male victims of partner violence. Data appear to suggest that the effects of male-perpetrated partner violence on perceived family functioning may be larger than that of female-perpetrated partner violence.

    2015-01-01

    Background Partner services have been a mainstay of public health sexually transmitted disease (STD) prevention programs for decades. The principal goals are to interrupt transmission and reduce STD morbidity and sequelae. In this paper, we review current literature with the goal of informing STD prevention programs. Methods We searched the literature for systematic reviews. We found nine reviews published between 2005 and 2014 (covering 108 studies). The reviews varied by study inclusion criteria (e.g., study methods, geographic location, infections). We abstracted major conclusions and recommendations from the reviews. Results Conclusions and recommendations were divided into patient referral interventions and provider referral interventions. For patient referral, there was evidence supporting the use of expedited partner therapy and interactive counseling, but not purely didactic instruction. Provider referral through Disease Intervention Specialists was efficacious and particularly well-supported for HIV. For other studies, modeling data and testing outcomes showed that partner notification in general reached high-prevalence populations. Reviews also suggested more focus on using technology and population-level implementation strategies. However, partner services may not be the most efficient means to reach infected persons. Conclusions Partner services programs constitute a large proportion of program STD prevention activities. Value is maximized by balancing a portfolio of patient and provider referral interventions and by blending partner notification interventions with other STD prevention interventions in overall partner services program structure. STD prevention needs program-level research and development to generate this portfolio. PMID:26779688

    Our analyses address the question of how bisexual Latino men organize their sexual partnerships. Heteronormativity can be understood as the set of social norms and normative structures that guide sexual partnering among men and women. We provide descriptive statistics to describe bisexual Latino men's sexual partnerships. Logistic and linear regression modeling were used to explore bivariate and multivariate relationships. Of our total sample (N = 142), 41.6 % had unprotected vaginal intercourse 2 months prior to the interview; 21.8 % had unprotected anal intercourse with female partners; 37.5 % had unprotected insertive anal intercourse with male partners; and 22.5 % had unprotected receptive anal intercourse with male partners. In our multivariate model, machismo was directly associated with meeting female partners through formal spaces (workplace, school, and/or church), but inversely associated with meeting male partners in formal spaces. Machismo was positively associated with meeting male sex partners through social networks (i.e., friendship and kinship networks). The more comfortable men were with homosexuality the less likely they were to meet men online and the more likely they were to meet men through social networks of friends and kinship. Interventions to reduce sexually transmitted diseases that target bisexual behavior as an epidemiological "bridge" of transmission from homosexual to heterosexual networks might very well benefit from a more complex understanding of how Latino bisexuality is patterned. Thus, this exploratory analysis might lead to a rethinking of how to address risk and vulnerability among Latino bisexual men and their sexual networks.

    To describe the effects of communication partner training on persons with aphasia and their communication partners. Specifically the systematic review addressed 3 clinical questions regarding the impact of partner training on language, communication activity and participation, psychosocial adjustment, and quality of life for adults with aphasia and their communication partners. Twenty-three terms were used to search 12 electronic databases (eg, PubMed, CINAHL, PsychINFO, PsychArticles, CSA Linguistics and Language Behavior Abstracts, Social Sciences Citation Index [Web of Science], SUMSearch, TRIP, EMBASE, REHABDATA, National Library for Health, Cochrane Database of Systematic Reviews) and the journal "Aphasiology." References from all relevant articles were hand-searched. Two reviewers independently applied inclusion criteria to select potential relevant articles from the titles and abstracts of references retrieved by the literature search. The full text of the remaining articles was reviewed by a 5-member panel, resulting in a corpus of 31 studies that met the final inclusion criteria. Two independent reviewers extracted the descriptive data related to the participants, the intervention, the outcome measures, and the results. The 5-member review team by consensus classified the studies using the American Academy of Neurology system for classification of evidence (2004). Evidence shows that communication partner training is effective in improving communication activities and/or participation of the communication partner and is probably effective in improving communication activities and/or participation of persons with chronic aphasia when they are interacting with trained communication partners. There is insufficient evidence to make recommendations related to the impact of partner training on persons with acute aphasia or the impact of training on language impairment, psychosocial adjustment, or quality of life for either the person with aphasia or the

    Cancer diagnosis influences both patients and their closest relatives. This cross-sectional study examined psychological distress among individuals whose partners had cancer in a population-based sample. Participants in the survey were citizens residing in Ohsaki City, Miyagi, Japan. Spouse pairs were identified by information of participants' relationship to the householder and address provided by municipality, and we collected self-report information on cancer history and current pain (but not the cause of pain). Psychological distress was evaluated using the Kessler 6 scale (K6). We identified 29,410 potential participants (14,705 couples), of which 23,766 (11,690 men and 12,076 women) were included in the analyses. A total of 1,374 participants (581 male and 793 female participants) had partners with history of cancer. Logistic regression analyses revealed that these participants, regardless of sex, did not show significantly higher risk of psychological distress (K6 score ≥ 13). When stratifying the analysis by partners' current pain, men whose partners had cancer and pain showed greater odds of psychological distress (odds ratio = 1.5, p = 0.04), compared with men whose partners had no cancer and had pain. However, male subjects whose partners had cancer but no pain did not show greater odds of psychological distress compared with men whose partners had no cancer and no pain. By contrast, in women whose partners had cancer, psychological distress was not associated with pain status. In conclusion, men whose partners had cancer and pain have higher risk of psychological distress, and its screening to these individuals may reduce the risk.

    To examine the association between sociodemographic, pregnancy-related variables and psychological and verbal intimate partner abuse, as well as to determine which of these variables are predictors of psychological and verbal intimate partner abuse during pregnancy. Intimate partner violence is a significant health issue, with severe implications to both mother and foetus. However, much of the research to date focuses on the outcomes of physical abuse. This article addresses the dearth in the literature by examining the association between sociodemographic, pregnancy-related variables and psychological and verbal intimate partner abuse during pregnancy. A survey research design was used. Three hundred postnatal women were recruited by convenience, nonproportional quota sampling technique. The WHO Violence Against Women Instrument was self-administered by participants. The association between categorical variables was assessed using Pearson's chi-square test, the strength of association using Cramer's V and the phi coefficient, and the identification of predictor variables for psychological and verbal abuse using logistic regression analysis. Four predictors were identified for psychological abuse, namely low education level in women, an unplanned pregnancy, experiencing two or more pregnancy-related health problems and living with an unemployed partner. However, unemployment in women, an unplanned pregnancy, fear of partner and a low education level of partner were identified as the predictors of verbal abuse. This study identified a number of variables that strongly predict psychological and verbal intimate partner abuse during pregnancy; however, it extends the available literature by identifying a low standard of education in males, unemployment and fear of the intimate partner as the significant predictors of psychological and verbal intimate partner abuse. Healthcare professionals should be aware of the predictors predisposing pregnant women to abuse. This

    It has been estimated that roughly 25% of all Deaf women in the United States are victims of intimate partner violence (Abused Deaf Women's Advocacy Services [ADWAS]), a figure similar to annual prevalence rates of 16% to 30% for intimate partners in the general population. One goal of the present study was to ascertain the prevalence of intimate partner violence victimization in a sample of Deaf female college students. When comparing the prevalence of physical assault, psychological aggression, and sexual coercion victimization to hearing female undergraduates, the current sample was approximately two times as likely to have experienced victimization in the past year.

    Learn the perceptions of patients with sexually transmitted infections and sexual partners who are notified of the infection. A descriptive and qualitative study, based on the collective subject discourse technique, was conducted in four healthcare centers of reference in Fortaleza, Ceará, from March to July 2014. The sample comprised 21 subjects (11 index patients and 10 notified partners). The index patients reported complicity, concern about the partner's health and revelation of diagnosis aiming to preserve the relationship. The partners showed antagonistic perceptions: tranquility-betrayal, fear of death, of incurability and the diagnosis, especially of HIV. The reasons for coming to a healthcare center were: fear of being sick, attenuation of guilt of infection transmission, need for diagnosis, early start of treatment. Fear of losing trust, insecurities when dealing with a sexual infection and being responsible or co-responsible for the transmission were the predominant feelings. Various types of partner notification were reported (verbal, telephone, notification card), according to individual convenience. This study suggests the use of alternative methods of notification and an integrated system of notification.

    Full Text Available The involvement of plant immunophilins in multiple essential processes such as development, various ways of adapting to biotic and abiotic stresses, and photosynthesis has already been established. Previously, research has demonstrated the involvement of three immunophilin genes (AtCYP19-1/ROC3, AtFKBP65/ROF2, and AtCYP57 in the control of plant response to invasion by various pathogens. Current research attempts to identify host target proteins for each of the selected immunophilins. As a result, candidate interactors have been determined and confirmed using a yeast 2-hybrid (Y2H system for protein–protein interaction assays. The generation of mutant isoforms of ROC3 and AtCYP57 harboring substituted amino acids in the in silico-predicted active sites became essential to achieving significant binding to its target partners. This data shows that ROF2 targets calcium-dependent lipid-binding domain-containing protein (At1g70790; AT1 and putative protein phosphatase (At2g30020; АТ2, whereas ROC3 interacts with GTP-binding protein (At1g30580; ENGD-1 and RmlC-like cupin (At5g39120. The immunophilin AtCYP57 binds to putative pyruvate decarboxylase-1 (Pdc1 and clathrin adaptor complex-related protein (At5g05010. Identified interactors confirm our previous findings that immunophilins ROC3, ROF2, and AtCYP57 are directly involved with stress response control. Further, these findings extend our understanding of the molecular functional pathways of these immunophilins.

    Prokaryotic toxin-antitoxin modules are involved in major physiological events set in motion under stress conditions. The toxin Doc (death on curing) from the phd/doc module on phage P1 hosts the C-terminal domain of its antitoxin partner Phd (prevents host death) through fold complementation....... This Phd domain is intrinsically disordered in solution and folds into an alpha-helix upon binding to Doc. The details of the interactions reveal the molecular basis for the inhibitory action of the antitoxin. The complex resembles the Fic (filamentation induced by cAMP) proteins and suggests a possible...... evolutionary origin for the phd/doc operon. Doc induces growth arrest of Escherichia coli cells in a reversible manner, by targeting the protein synthesis machinery. Moreover, Doc activates the endogenous E. coli RelE mRNA interferase but does not require this or any other known chromosomal toxin...

    Based upon fluorescence measurements, protein binding of some psychotropic agents (chlorpromazine, promethazine, and trifluoperazine) to human IgG and HSA was studied in aqueous cacodylate buffer, PH7. The interaction parameters determined from emission quenching of the proteins. The interaction parameters determined include the equilibrium constant (K), calculated from equations derived by Borazan and coworkers, the number of binding sites (n) available to the monomer molecules on a single protein molecule. The results revealed a high level of affinity, as reflected by high values of K, and the existence of specific binding sites, since a limited number of n values are obtained. 39 tabs.; 37 figs.; 83 refs

  14. Preparing Scientists to be Community Partners

    Pandya, R. E.

    2012-12-01

    Many students, especially students from historically under-represented communities, leave science majors or avoid choosing them because scientific careers do not offer enough opportunity to contribute to their communities. Citizen science, or public participation in scientific research, may address these challenges. At its most collaborative, it means inviting communities to partner in every step of the scientific process from defining the research question to applying the results to community priorities. In addition to attracting and retaining students, this level of community engagement will help diversify science, ensure the use and usability of our science, help buttress public support of science, and encourage the application of scientific results to policy. It also offers opportunities to tackle scientific questions that can't be accomplished in other way and it is demonstrably effective at helping people learn scientific concepts and methods. In order to learn how to prepare scientists for this kind of intensive community collaboration, we examined several case studies, including a project on disease and public health in Africa and the professionally evaluated experience of two summer interns in Southern Louisiana. In these and other cases, we learned that scientific expertise in a discipline has to be accompanied by a reservoir of humility and respect for other ways of knowing, the ability to work collaboratively with a broad range of disciplines and people, patience and enough career stability to allow that patience, and a willingness to adapt research to a broader set of scientific and non-scientific priorities. To help students achieve this, we found that direct instruction in participatory methods, mentoring by community members and scientists with participatory experience, in-depth training on scientific ethics and communication, explicit articulation of the goal of working with communities, and ample opportunity for personal reflection were essential

    Ecological Momentary Assessment (EMA) was used to investigate associations between, and variations in, ejaculatory control and ejaculation latency time (ELT) over repeated measurements of sexual activities. Differences between measures recorded in partnered or non-partnered settings were also investigated. The sample consisted of 21 male Finns aged 18 years or above, contributing a total of 158 reports of partnered and non-partnered sexual activities over a six-week period. In the context of non-partnered sexual activities, after controlling for within-subjects dependence, ELTs between events were predictive of one another, but ELT did not predict ejaculatory control when measured simultaneously, nor at subsequent events. Also, ejaculatory control could not predict simultaneously measured ELT or ejaculatory control at subsequent events. During partnered sexual activities, both ejaculatory control and ELT could be accurately predicted by observing ejaculatory control at prior events. In this context, ejaculatory control could also reliably predict simultaneously measured ELT. ELT or ejaculatory control during partnered sexual activity could not be predicted by observing ELT at prior events. Between-event correlations were generally low, indicating considerable variation in ejaculatory functioning over time. EMA is a thrifty assessment method for studying variations in ejaculatory function, and is likely suitable for studying sexual dysfunctions in general.

    Nearly one-third of South African men report enacting intimate partner violence. Beyond the direct health consequences for women, intimate partner violence is also linked to varied risk behaviours among men who enact it, including alcohol abuse, risky sex, and poor healthcare uptake. Little is known about how to reduce violence perpetration among men. We conducted retrospective, in-depth interviews with men (n = 53) who participated in a rural South African programme that targeted masculinities, HIV risk, and intimate partner violence. We conducted computer-assisted thematic qualitative coding alongside a simple rubric to understand how the programme may lead to changes in men's use of intimate partner violence. Many men described new patterns of reduced alcohol intake and improved partner communication, allowing them to respond in ways that did not lead to the escalation of violence. Sexual decision-making changed via reduced sexual entitlement and increased mutuality about whether to have sex. Men articulated the intertwined nature of each of these topics, suggesting that a syndemic lens may be useful for understanding intimate partner violence. These data suggest that alcohol and sexual relationship skills may be useful levers for future violence prevention efforts, and that intimate partner violence may be a tractable issue as men learn new skills for enacting masculinities in their household and in intimate relationships.

  17. Identification and characterization of Iporin as a novel interaction partner for rab1

    2005-03-01

    Full Text Available Abstract Background The small GTPase rab1a and its isoform rab1b are essential regulating components in the vesicle transport between the ER and the Golgi apparatus. Rab1 is thought to act as a molecular switch and can change between an active GTP-bound and an inactive GDP-bound conformation. To elucidate the function of rab1, several approaches have been established to isolate effector proteins, which interact with the activated conformation of rab1. To date p115, GM130, golgin-84 and MICAL have been identified as direct interacting partners. Together with rab1, these molecules are components of a protein complex, which mediates and regulates intracellular vesicle transport. Results Here, we report the characterization of Iporin, which is similar to KIAA0375 as a novel rab1-interacting protein. It was initially identified by yeast two-hybrid screening experiments with the active mutant of rab1b (rab1b Q67R as bait. Iporin contains a SH3 domain and two polyproline stretches, which are known to play a role in protein/protein interactions. In addition, Iporin encloses a RUN domain, which seems to be a major part of the rab1binding domain (R1BD. Iporin is ubiquitously expressed and immunofluorescence staining displays a cytosolic punctual distribution. Interestingly, we also show that Iporin interacts with another rab1 interacting partner, the GM130 protein. Conclusion Our results demonstrate that Iporin is a potential new interacting partner of rab1. Iporin is different from already identified rab1 interacting proteins concerning protein structure and cellular localization. We conclude that Iporin might function as a link between the targeting of ER derived vesicles, triggered by the rab1 GTPase and a signaling pathway regulated by molecules containing SH3 and/or poly-proline regions. The characterization of this novel intermolecular relation could help to elucidate how vesicles find their way from ER to the Golgi apparatus.

    2015-06-01

    Escherichia coli maltose-binding protein (MBP) is exceptionally effective at promoting the solubility of its fusion partners. However, there are conflicting reports in the literature claiming that (1) MBP is an effective solubility enhancer only when it is joined to the N-terminus of an aggregation-prone passenger protein, and (2) MBP is equally effective when fused to either end of the passenger. Here, we endeavor to resolve this controversy by comparing the solubility of a diverse set of MBP fusion proteins that, unlike those analyzed in previous studies, are identical in every way except for the order of the two domains. The results indicate that fusion proteins with an N-terminal MBP provide an excellent solubility advantage along with more robust expression when compared to analogous fusions in which MBP is the C-terminal fusion partner. We find that only intrinsically soluble passenger proteins (i.e., those not requiring a solubility enhancer) are produced as soluble fusions when they precede MBP. We also report that even subtle differences in inter-domain linker sequences can influence the solubility of fusion proteins. Published by Elsevier Inc.

    The expression of recombinant proteins in Escherichia coli often leads to inactive aggregated proteins known as the inclusion bodies. To date, the best available tool has been the use of fusion tags, including the carbohydrate-binding protein; e.g., the maltose-binding protein (MBP) that enhances the solubility of recombinant proteins. However, none of these fusion tags work universally with every partner protein. We hypothesized that galectins, which are also carbohydrate-binding proteins, may help as fusion partners in folding the mammalian proteins in E. coli. Here we show for the first time that a small soluble lectin, human galectin-1, one member of a large galectin family, can function as a fusion partner to produce soluble folded recombinant human glycosyltransferase, {beta}-1,4-galactosyltransferase-7 ({beta}4Gal-T7), in E. coli. The enzyme {beta}4Gal-T7 transfers galactose to xylose during the synthesis of the tetrasaccharide linker sequence attached to a Ser residue of proteoglycans. Without a fusion partner, {beta}4Gal-T7 is expressed in E. coli as inclusion bodies. We have designed a new vector construct, pLgals1, from pET-23a that includes the sequence for human galectin-1, followed by the Tev protease cleavage site, a 6x His-coding sequence, and a multi-cloning site where a cloned gene is inserted. After lactose affinity column purification of galectin-1-{beta}4Gal-T7 fusion protein, the unique protease cleavage site allows the protein {beta}4Gal-T7 to be cleaved from galectin-1 that binds and elutes from UDP-agarose column. The eluted protein is enzymatically active, and shows CD spectra comparable to the folded {beta}4Gal-T1. The engineered galectin-1 vector could prove to be a valuable tool for expressing other proteins in E. coli.

    Using the energy of ATP hydrolysis, ABC transporters catalyze the trans-membrane transport of molecules. In bacteria, these transporters partner with a high-affinity substrate-binding protein (SBP) to import essential micronutrients. ATP binding by Type I ABC transporters (importers of amino acids, sugars, peptides, and small ions) stabilizes the interaction between the transporter and the SBP, thus allowing transfer of the substrate from the latter to the former. In Type II ABC transporters (importers of trace elements, e.g. vitamin B 12 , heme, and iron-siderophores) the role of ATP remains debatable. Here we studied the interaction between the Yersinia pestis ABC heme importer (HmuUV) and its partner substrate-binding protein (HmuT). Using real-time surface plasmon resonance experiments and interaction studies in membrane vesicles, we find that in the absence of ATP the transporter and the SBP tightly bind. Substrate in excess inhibits this interaction, and ATP binding by the transporter completely abolishes it. To release the stable docked SBP from the transporter hydrolysis of ATP is required. Based on these results we propose a mechanism for heme acquisition by HmuUV-T where the substrate-loaded SBP docks to the nucleotide-free outward-facing conformation of the transporter. ATP binding leads to formation of an occluded state with the substrate trapped in the trans-membrane translocation cavity. Subsequent ATP hydrolysis leads to substrate delivery to the cytoplasm, release of the SBP, and resetting of the system. We propose that other Type II ABC transporters likely share the fundamentals of this mechanism. © 2017 by The American Society for Biochemistry and Molecular Biology, Inc.

    Using the continuous Demographic and Health Surveys (2005-2012) for Peru, we employ multinomial logistic regression estimates to assess risk for intimate partner violence (IPV). Using empowerment and gender frameworks for IPV, we find that women making more household decisions jointly are less likely to experience physical violence. We also find that education is negatively associated with IPV, unless a woman's attainment exceeds her partner's. Although women earning more than their partners are more likely to experience violence, joint decision-makers have a lower risk of moderate physical violence even when their status exceeds that of a male partner. By adding measures for relationship dynamics, we highlight the ways decision-making within the household contributes to violence risk for women. While deviating from male-breadwinning norms can result in violence, risk factors are conditioned on the nature of cooperation within a partnership. Our findings suggest that shared power within the household reduces IPV risk.

    2002-02-01

    Domestic rams display a naturally occurring variation in sexual partner preference, such that 6-10% of range-bred populations prefer male sexual partners (male-oriented) in contrast to the majority of rams that prefer female sexual partners (female-oriented). Male-oriented rams exhibit hormone profiles and stress responses distinctly different from their heterosexual counterparts. These differences include reduced circulating levels of testosterone that arise after anesthetization. Lower levels of aromatase activity in the medial preoptic area and estrogen receptor in the amygdala were also measured in male-oriented versus female-oriented rams and may represent an important link to sexual behavior that should be investigated. It is anticipated that the male-oriented ram model will be useful for studies aimed at identifying both the activational and organizational components and the neuronal substrates of male sexual partner preferences.

    Homicide is an important cause of premature mortality globally, but evidence for the magnitude of homicides by intimate partners is scarce and hampered by the large amount of missing information about the victim-offender relationship. The objective of the study was to estimate global and regional prevalence of intimate partner homicide. A systematic search of five databases (Medline, Global Health, Embase, Social Policy, and Web of Science) yielded 2167 abstracts, and resulted in the inclusion of 118 full-text articles with 1122 estimates of the prevalence of intimate partner homicide after double-blind screening. All studies were included that reported the number or proportion of women or men who were murdered by an intimate partner in a country, province, or town, using an inclusive definition of an intimate partner. Additionally, a survey of official sources of 169 countries provided a further 53 estimates. We selected one estimate per country-year using a quality assessment decision algorithm. The median prevalence of intimate partner homicide was calculated by country and region overall, and for women and men separately. Data were obtained for 66 countries. Overall 13·5% (IQR 9·2-18·2) of homicides were committed by an intimate partner, and this proportion was six times higher for female homicides than for male homicides (38·6%, 30·8-45·3, vs 6·3%, 3·1-6·3). Median percentages for all (male and female) and female intimate partner homicide were highest in high-income countries (all, 14·9%, 9·2-18·2; female homicide, 41·2%, 30·8-44·5) and in southeast Asia (18·8%, 11·3-18·8; 58·8%, 58·8-58·8). Adjustments to account for unknown victim-offender relationships generally increased the prevalence, suggesting that results presented are conservative. At least one in seven homicides globally and more than a third of female homicides are perpetrated by an intimate partner. Such violence commonly represents the culmination of a long history of abuse

    Previous studies in Caenorhabditis elegans showed that RPM-1 (Regulator of Presynaptic Morphology-1) regulates axon termination and synapse formation. To understand the mechanism of how rpm-1 functions, we have used mass spectrometry to identify RPM-1 binding proteins, and have identified RAE-1 (RNA Export protein-1) as an evolutionarily conserved binding partner. We define a RAE-1 binding region in RPM-1, and show that this binding interaction is conserved and also occurs between Rae1 and the human ortholog of RPM-1 called Pam (protein associated with Myc). rae-1 loss of function causes similar axon and synapse defects, and synergizes genetically with two other RPM-1 binding proteins, GLO-4 and FSN-1. Further, we show that RAE-1 colocalizes with RPM-1 in neurons, and that rae-1 functions downstream of rpm-1. These studies establish a novel postmitotic function for rae-1 in neuronal development.

    To update a previous systematic review describing the effect of communication partner training on individuals with aphasia and their communication partners, with clinical questions addressing effects of partner training on language, communication activity/participation, psychosocial adjustment, and quality of life. Twelve electronic databases were searched using 23 search terms. References from relevant articles were hand searched. Three reviewers independently reviewed abstracts, excluding those that failed to meet inclusion criteria. Thirty-two full text articles were reviewed by 2 independent reviewers. Articles not meeting inclusion criteria were eliminated, resulting in a corpus of 25 articles for full review. For the 25 articles, 1 reviewer extracted descriptive data regarding participants, intervention, outcome measures, and results. A second reviewer verified the accuracy of the extracted data. The 3-member review team classified studies using the American Academy of Neurology levels of evidence. Two independent reviewers evaluated each article using design-specific tools to assess research quality. All 25 of the current review articles reported positive changes from partner training. Therefore, to date, 56 studies across 2 systematic reviews have reported positive outcomes from communication partner training in aphasia. The results of the current review are consistent with the previous review and necessitate no change to the earlier recommendations, suggesting that communication partner training should be conducted to improve partner skill in facilitating the communication of people with chronic aphasia. Additional high-quality research is needed to strengthen the original 2010 recommendations and expand recommendations to individuals with acute aphasia. High-quality clinical trials are also needed to demonstrate implementation of communication partner training in complex environments (eg, health care). Copyright © 2016 American Congress of

    Smartphone applications (apps) are increasingly used to facilitate casual sexual relationships, increasing the risk of sexually transmitted diseases (STDs). In STD investigations, traditional contact elicitation methods can be enhanced with smartphone technology during field interviews. In 2013, the Monroe County Department of Public Health conducted a large, multi-infection STD investigation among men who have sex with men (MSM) using both index case and cluster interviews. When patients indicated meeting sexual partners online, disease intervention specialists (DISs) had access to smartphone apps and were able to elicit partners through access to inboxes and profiles where traditional contact information was lacking. Social network mapping was used to display the extent of the investigation and the impact of access to smartphones on the investigation. A total of 14 index patient interviews and two cluster interviews were conducted; 97 individuals were identified among 117 sexual dyads. On average, eight partners were elicited per interview (range: 1-31). The seven individuals who used apps to find partners had an average of three Internet partners (range: 1-5). Thirty-six individuals either had a new STD (n=7) or were previously known to be HIV-positive (n=29). Of the 117 sexual dyads, 21 (18%) originated either online (n=8) or with a smartphone app (n=13). Of those originating online or with a smartphone app, six (29%) partners were located using the smartphone and two (10%) were notified of their exposure via a website. Three of the new STD/HIV cases were among partners who met online. Smartphone technology used by DISs in the field improved contact elicitation and resulted in successful partner notification and case finding.

    2003-07-01

    The WHO has declared that violence is a leading worldwide public health problem with intimate partner violence one of the most common forms of violence against women (2002). Health care providers are frequently among the first to see victims of intimate partner violence and must strive to provide appropriate and effective care to abused women. Violence by intimate partners can be prevented. Occupational health nurses have a unique opportunity to intervene with abused women. Routine screening for intimate partner violence increases the likelihood of violence identification, leading to early intervention that may prevent trauma and injury. Occupational health nurses can foster a caring and confidential workplace where abused women feel safe to disclose the violence in their lives and trust that the nurse will provide treatment. A safe and healthy workplace, where abused women feel comfortable disclosing intimate partner violence and seeking treatment may also protect coworkers from the stress and violence that may potentially affect them. Occupational health nurses need to add screening for and treatment of intimate partner violence to their current health promotion and prevention activities to benefit all employees.

    2013-12-01

    Full Text Available This study investigated the association between unintended pregnancy and intimate partner violence before pregnancy. A cross-sectional study was carried out with 1,054 women, aged 18 to 49, in Recife, Northeastern Brazil, from July 2005 to March 2006. Non-conditional logistic regression analysis was performed with a hierarchical strategy for entering variables into the model, according to the conceptual framework defined. Unintended pregnancy was reported by 60.3% (636 women. Intimate partner violence prior to the pregnancy was associated with unintended pregnancy (ORadj = 1.57; 95%CI: 1.17-2.11, even when adjusted for the women's sociodemographic characteristics, the partner's behaviour, and the relationship dynamic. When the association was adjusted for the use of contraception and the partner's refusal to use contraception, the association was no longer significant, suggesting that the effect of partner violence on unintended pregnancy may be mediated by these variables. The findings point to the need of screening for intimate partner violence in reproductive health services.

    Full Text Available The aim of this study is to present a psychometrically sound instrument to assess intimate partner violence offenders’ responsibility attributions: the Intimate Partner Violence Responsibility Attribution Scale. The scale was administrated to 423 adult male intimate partner violence offenders court-mandated to a community-based intervention program. A three factor structure (responsibility attribution to the legal system, responsibility attribution to the victim, and responsibility attribution to the offender personal context was supported using confirmatory factor analysis. Reliability of the scales in this study was estimated using Cronbach’s alpha, ρ and greatest lower bound. The Intimate Partner Violence Responsibility Attribution Scale correlated in theoretically expected ways with variables used to assess construct validity (system blaming, problems with partner, and responsibility assumption and with variables used to assess criterion-related validity (satisfaction with legal system, victim-blaming attitudes, alcohol consumption, hostile sexism, stressful life events, social desirability, impulsivity and household income. Results support the validity and reliability of the Intimate Partner Violence Responsibility Attribution Scale

    2005-01-01

    This study explored the importance of weight in college students' dating relationships and the expression of weight-related concerns between dating romantic partners. In a survey of 554 undergraduates, we found that overweight women were less likely to be dating than their peers, and that weight was positively correlated with relationship satisfaction in men, but negatively correlated with satisfaction in women. We also found that over 30% of students in exclusive relationships had either been told by their partner (or had told their partner) to gain or lose weight. While male partners were typically told to gain weight, female partners were as likely to be told to lose as gain weight. Women's weight-loss attempts and self-esteem were not related to being the targets of these comments, but women told to lose weight reported lower relationship satisfaction; men's self-esteem was not related to being the targets of these comments, but men told to gain weight reported lower relationship satisfaction. Although our results support prior research suggesting that weight is differentially important for men and women in romantic relationships, they challenge the hypothesis that individual romantic partners are a primary source of students' body dissatisfaction and weight concerns.

  7. The Neurobiology of Sexual Partner Preferences in Rams

    Roselli, Charles E.; Stormshak, Fred

    2009-01-01

    The question of what causes a male animal to seek out and choose a female as opposed to another male mating partner is unresolved and remains an issue of considerable debate. The most developed biologic theory is the perinatal organizational hypothesis, which states that perinatal hormone exposure mediates sexual differentiation of the brain. Numerous animal experiments have assessed the contribution of perinatal testosterone and/or estradiol exposure to the development of a male-typical mate preference, but almost all have used hormonally manipulated animals. In contrast, variations in sexual partner preferences occur spontaneously in domestic rams, with as many as 8% of the population exhibiting a preference for same-sex mating partners (male-oriented rams). Thus, the domestic ram is an excellent experimental model to study possible links between fetal neuroendocrine programming of neural mechanisms and adult sexual partner preferences. In this review, we present an overview of sexual differentiation in relation to sexual partner preferences. We then summarize results that test the relevance of the organizational hypothesis to expression of same-sex sexual partner preferences in rams. Finally, we demonstrate that the sexual differentiation of brain and behavior in sheep do not depend critically on aromatization of testosterone to estradiol. PMID:19446078

    Cyclin D3, like cyclin D1 and D2 isoforms, is a crucial component of the core cell cycle machinery in mammalian cells. It also exhibits its unique properties in many other physiological processes. In the present study, using yeast two-hybrid screening, we identified ERK3, an atypical mitogen-activated protein kinase (MAPK), as a cyclin D3 binding partner. GST pull-down assays showed that cyclin D3 interacts directly and specifically with ERK3 in vitro. The binding of cyclin D3 and ERK3 was further confirmed in vivo by co-immunoprecipitation assay and confocal microscopic analysis. Moreover, carboxy-terminal extension of ERK3 was responsible for its association with intact cyclin D3. These findings further expand distinct roles of cyclin D3 and suggest the potential activity of ERK3 in cell proliferation

    Identifying venues where women meet sexual partners, particular partners who increase women's risk of acquiring HIV, could inform prevention efforts. We categorized venues where women enrolled in HPTN 064 reported meeting their last three sex partners as: (1) Formal, (2) Public, (3) Private, and (4) Virtual spaces. We used multinomial logistic regression to assess the association between these venues and women's individual characteristics and reports of their partners' HIV risk characteristics. The 2099 women reported meeting 3991 partners, 51 % at Public, 30 % Private, 17 % Formal and 3 % at Virtual venues. Women meeting partners at Formal venues reported more education and condom use than women meeting partners at other venues. Fewer partners met through Formal venues had "high" risk characteristics for HIV than through other venues and hence may pose less risk of HIV transmission. HIV prevention interventions can help women choose partners with fewer risk characteristics across all venue types.

    Provoked vestibulodynia (PVD) is a highly prevalent vulvovaginal pain condition that results in significant sexual dysfunction, psychological distress, and reduced quality of life. Although some intra-individual psychological factors have been associated with PVD, studies to date have neglected the interpersonal context of this condition. We examined whether partner responses to women's pain experience-from the perspective of both the woman and her partner-are associated with pain intensity, sexual function, and sexual satisfaction. One hundred ninety-one couples (M age for women=33.28, standard deviation [SD]=12.07, M age for men=35.79, SD=12.44) in which the woman suffered from PVD completed the spouse response scale of the Multidimensional Pain Inventory, assessing perceptions of partners' responses to the pain. Women with PVD also completed measures of pain, sexual function, sexual satisfaction, depression, and dyadic adjustment. Dependent measures were women's responses to: (i) a horizontal analog scale assessing the intensity of their pain during intercourse; (ii) the Female Sexual Function Index; and (iii) the Global Measure of Sexual Satisfaction Scale. Controlling for depression, higher solicitous partner responses were associated with higher levels of women's vulvovaginal pain intensity. This association was significant for partner-perceived responses (β=0.29, PPVD by suggesting that partner responses to pain affect pain intensity and sexual satisfaction in affected women. © 2010 International Society for Sexual Medicine.

    In this qualitative study, we explored women's pregnancy intentions and experiences of intimate partner violence before, during and after pregnancy. Unintended pregnancies in the context of intimate partner violence can have serious health, social and economic consequences for women and their children. Feminist and phenomenological philosophies underpinned the study to gain a richer understanding of women's experiences. Eleven women who had been pregnant in the previous two years were recruited from community-based women's refuges in one region of the UK. Of the 11 women, eight had unplanned pregnancies, two reported being coerced into early motherhood, and only one woman had purposively planned her pregnancy. Multiple in-depth interviews focused on participants' accounts of living with intimate partner violence. Experiential data analysis was used to identify, analyse and highlight themes. Three major themes were identified: men's control of contraception, partner's indiscriminate response to the pregnancy and women's mixed feelings about the pregnancy. Participants reported limited influence over their sexual relationship and birth control. Feelings of vulnerability about themselves and fear for their unborn babies' safety were intensified by their partners' continued violence during pregnancy. Women experiencing intimate partner violence were more likely to have an unintended pregnancy. This could be attributed to male dominance and fear, which impacts on a woman's ability to manage her birth control options. The women's initial excitement about their pregnancy diminished in the face of uncertainty and ongoing violence within their relationship. Women experiencing violence lack choice in relation to birth control options leading to unintended pregnancies. Interpreting the findings from the victim-perpetrator interactive spin theory of intimate partner violence provides a possible framework for midwives and nurses to better understand and respond to women

    Our analyses address the question of how bisexual Latino men organize their sexual partnerships. Heteronormativity can be understood as the set of social norms and normative structures that guide sexual partnering among men and women. We provide descriptive statistics to describe bisexual Latino men’s sexual partnerships. Logistic and linear regression modeling were used to explore bivariate and multivariate relationships. Of our total sample (N = 142), 41.6% had unprotected vaginal intercourse 2 months prior to the interview; 21.8 % had unprotected anal intercourse with female partners; 37.5 % had unprotected insertive anal intercourse with male partners; and 22.5 % had unprotected receptive anal intercourse with male partners. In our multivariate model, machismo was directly associated with meeting female partners through formal spaces (workplace, school, and/or church), but inversely associated with meeting male partners in formal spaces. Machismo was positively associated with meeting male sex partners through social networks (i.e., friendship and kinship networks). The more comfortable men were with homosexuality the less likely they were to meet men online and the more likely they were to meet men through social networks of friends and kinship. Interventions to reduce sexually transmitted diseases that target bisexual behavior as an epidemiological “bridge” of transmission from homosexual to heterosexual networks might very well benefit from a more complex understanding of how Latino bisexuality is patterned. Thus, this exploratory analysis might lead to a rethinking of how to address risk and vulnerability among Latino bisexual men and their sexual networks. PMID:25128415

    Male-to-female intimate partner violence remains a worldwide public health issue with adverse physical and psychological consequences for victims, perpetrators and children. Personality disorders, addiction, trauma and mood symptoms are established risk factors for intimate partner violence perpetration and factor prominently into a recovery-oriented treatment approach. We reviewed the partner violence literature for detailed reports of traditional as well as innovative, integrated treatment approaches. Empirically based recommendations for intervention programs and the policies that guide intervention efforts are offered. Nascent research suggests that integrated treatment models utilising a holistic approach to account for psychological comorbidity and interventions that involve a motivational interviewing component appear promising in terms of significantly improving intimate partner violence treatment compliance and reducing subsequent acts of physical partner violence. Further, methodologically rigorous research is required to fully assess the benefits of traditional and integrated treatment options. We have advanced several recommendations, including the development of and exclusive reliance upon empirically supported treatments, conducting a thorough risk and needs assessment of the offender and the immediate family to facilitate appropriate treatment referrals, integrating content to foster the offender's internal motivation to change maladaptive behaviours, and attempting to minimise offender treatment burdens through the strategic use of integrated treatment models. Intimate partner violence is a complicated and nuanced problem that is perpetrated by a heterogeneous population and requires greater variability in integrated treatment options.

    We investigated the cognitive mechanisms underlying turn-taking joint action in 42-month-old children (Experiment 1) and adults (Experiment 2) using a behavioral task of dressing a virtual bear together. We aimed to investigate how participants represent a partners' behavior, i.e., in terms of specific action kinematics or of action effects. The bear was dressed by pressing a smaller and a bigger button. In the Action-response task, instructions asked participants to respond to the partner by pressing the same or opposite button; in the Action-effect task they had to respond to the partner's action effect by dressing the bear with the lacking part of the clothing, which in some cases implied pressing the same button and in other cases implied pressing the opposite button. In 50% of the trials, the partner's association between each button and the ensuing effect (dressing the bear with t-shirt or pants) was reversed, while it never changed for participants. Both children and adults showed no effect of physical congruency of actions, but showed impaired performance in the Action-effect task if their partner achieved her effect through a different action-effect association than their own. These results suggest that, when encoding their partner's actions, agents are influenced by action-effect associations that they learnt through their own experience. While interference led to overt errors in children, it caused longer reaction times in adults, suggesting that a flexible cognitive control (that is still in development in young children) is required to take on the partner's perspective.

    The interplay between the nervous and immune systems is gradually being unraveled. We previously reported in the mouse the novel soluble immune system factor ISRAA, whose activation in the spleen is central nervous system-dependent. We also showed that ISRAA plays a role in modulating anti-infection immunity. Herein, we report the genomic description of the israa locus, along with some insights into the structure-function relationship of the protein. Our findings revealed that israa is nested within intron 6 of the mouse zmiz1 gene. Protein sequence analysis revealed a typical SH2 binding motif (Y102TEV), with Fyn being the most likely binding partner. Docking simulation showed a favorable conformation for the ISRAA-Fyn complex, with a specific binding mode for the binding of the YTEV motif to the SH2 domain. Experimental studies showed that in vitro, recombinant ISRAA is phosphorylated by Fyn at tyrosine 102. Cell transfection and pull-down experiments revealed Fyn as a binding partner of ISRAA in the EL4 mouse T-cell line. Indeed, we demonstrated that ISRAA downregulates T-cell activation and the phosphorylation of an activation tyrosine (Y416) of Src-family kinases in mouse splenocytes. Our observations highlight ISRAA as a novel Fyn binding protein that is likely to be involved in a signaling pathway driven by the nervous system.

    The physical status of water in seeds has a pivotal role in determining the physiological reactions that can take place in the dry state. Using water sorption isotherms from cotyledon and axis tissue of five leguminous seeds, the strength of water binding and the numbers of binding sites have been estimated using van't Hoff analyses and the D'Arcy/Watt equation. These parameters of water sorption are calculated for each of the three regions of water binding and for a range of temperatures. Water sorption characteristics are reflective of the chemical composition of the biological materials as well as the temperature at which hydration takes place. Changes in the sorption characteristics with temperature and hydration level may suggest hydration-induced structural changes in cellular components.

    Full Text Available The paper assumes that strategic partnering, as one of the more mature forms of inter-organisational cooperation, is also an effective method of support for strategic activities of enterprises. In the light of the above, the use of strategic partnering in processes aimed at enhancing their competitiveness was proposed. The aim of the analyses is to identify and systematise the key actions in the mechanism of building competitiveness through strategic partnering of enterprises. For its implementation, a review of literature in the field of theory of organisation, theory of cooperation and partnering as well as theory of competitiveness was carried out. Empirical research to verify the initial theoretical assumptions was also conducted. Quantitative research (surveys and qualitative research (extended case studies was carried out. The study was based on the research procedure modelled on forecasting methods of searching for solutions to organisational problems, i.e. on creative (lateral thinking. As a result, the algorithm of building competitiveness through mature strategic partnering was formulated and recommendations were made as to the possibility of its practical use.

  18. Gender and perceptions of romantic partners' sexual risk.

    Research shows that in most situations, women perceive themselves to be at greater risk of harm than do men. Gustafson's gender role perspective on risk perception suggests that this is because women are socialized to feel that they need protection, especially from men. Based on Gustafson's gender role perspective on sex differences in risk perception, we predicted that in at least one context, perception of romantic partners' sexual risk, this gender difference would be reversed. Specifically, women should rate boyfriends as having lower risk for sexually transmitted infections (STIs) than boyfriends rate themselves having. In two studies, we examined heterosexual couples and compared women's perceptions of their boyfriends' sexual risk level with the boyfriend's self-perception of sexual risk. Self-reported measures of risk for STIs, perception of romantic partners' risk for STIs. On multiple measures, women rated their boyfriends as having a lower risk for STIs than the men rated themselves. Men did not show this pattern and, in some cases, showed the reverse pattern of perceiving their girlfriends to have a greater level of risk than girlfriends themselves believed they had. Consistent with Gustafson's gender role perspective on risk perception, heterosexual women perceived their romantic partners as relatively less risky in terms of STI risk than men perceived themselves. One potential implication of this finding is that women may be less likely to protect themselves against disease in close romantic relationships because they believe that their partners are low risk, regardless of the partners' actual risk levels.

    To assess factors related to partner violence against pregnant women. Data were collected from 383 pregnant women eligible attending five family medicine units of the Mexican institute of social security in Mexico City, Mexico, between September 2003 and August 2004. Data collection was carried out using a questionnaire developed for the study. Of all women interviewed, 120 (31.1%) reported that they had been exposed to psychological and/or physical and/or sexual violence perpetrated by their partners during the current pregnancy; 10% reported combined violence and 21% isolated violence. Psychological violence was most frequently reported (in 93% of the "experienced violence" group). As for their perception of violence there was not found any significant differences between those women who had experienced versus those who did not experience violence. Only about 20% of women had knowledge of centers for women victims of violence. The factors significantly associated with partner violence among pregnant women included: being single (OR=3.02; 95% CI: 1.17;7.83), being unmarried and living with a partner (OR=2.22; 95% CI: 1.11;4.42), history of violence during childhood (OR= 3.08; 95% CI: 1.62;5.85), alcohol consumption by the partner (OR=1.87; 95% CI: 1.02;3.42) and emotional distress among women (OR=4.17; 95% CI: 1.12;15.51). The study results stress other research findings that violence against pregnant Mexican women is still common.

    Full Text Available OBJECTIVE : To investigate the association between common mental disorders and intimate partner violence during pregnancy. METHODS : A cross sectional study was carried out with 1,120 pregnant women aged 18-49 years old, who were registered in the Family Health Program in the city of Recife, Northeastern Brazil, between 2005 and 2006. Common mental disorders were assessed using the Self-Reporting Questionnaire (SRQ-20. Intimate partner violence was defined as psychologically, physically and sexually abusive acts committed against women by their partners. Crude and adjusted odds ratios were estimated for the association studied utilizing logistic regression analysis. RESULTS : The most common form of partner violence was psychological. The prevalence of common mental disorders was 71.0% among women who reported all form of violence in pregnancy and 33.8% among those who did not report intimate partner violence. Common mental disorders were associated with psychological violence (OR 2.49, 95%CI 1.8;3.5, even without physical or sexual violence. When psychological violence was combined with physical or sexual violence, the risk of common mental disorders was even higher (OR 3.45; 95%CI 2.3;5.2. CONCLUSIONS : Being assaulted by someone with whom you are emotionally involved can trigger feelings of helplessness, low self-esteem and depression. The pregnancy probably increased women`s vulnerability to common mental disorders

    Approximately one in five adults engage in heavy episodic drinking (HED), a behavior with serious health and social consequences. Environmental, intrapersonal, and interpersonal factors contribute to and perpetuate HED. Prior research supports the partner influence hypothesis where partners influence each other's HED. We examined the partner influence hypothesis longitudinally over three years in heterosexual couples in serious romantic relationships, while exploring possible sex differences in the magnitude of partner influence. One-hundred-and-seventy-nine heterosexual couples in serious relationships (38.5% married at baseline) completed a measure of HED at baseline and again three years later. Using actor-partner interdependence modelling, results showed actor effects for both men and women, with HED remaining stable for each partner from baseline to follow-up. Significant partner effects were found for both men and women, who both positively influenced their partners' HED over the three-year follow-up. The partner influence hypothesis was supported. Results indicated partner influences on HED occur over the longer term and apply to partners in varying stages of serious romantic relationships (e.g., cohabiting, engaged, married). Women were found to influence their partners' HED just as much as men influence their partners' HED. Findings suggest HED should be assessed and treated as a couples' issue rather than simply as an individual risky behavior. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Humanin (HN), a 24-amino acid peptide encoded by the mitochondrial 16S rRNA gene, was discovered by screening a cDNA library from the occipital cortex of a patient with Alzheimer's disease (AD) for a protection factor against AD-relevant insults. Earlier, using the yeast two-hybrid system, we have identified the M-phase phosphoprotein 8 (MPP8) as a binding partner for HN. In the present work, we further confirmed interaction of HN with MPP8 in co-immunoprecipitation experiments and localized an MPP8-binding site in the region between 5 and 12 aa. of HN. We have also shown that an MPP8 fragment (residues 431-560) is sufficient to bind HN. Further studies on functional consequences of the interaction between the potential oncopetide and the oncoprotein may elucidate some aspects of the molecular mechanisms of carcinogenesis.

    The TATA binding protein (TBP) is the central core protein of the transcription factor II D that binds directly to the TATA box and therefore plays an integral part in eukaryotic transcription. This pivotal position of TBP is underlined by the vast number of interaction partners involved. Expression and purification of human TATA binding protein (hTBP) has remained a challenge due to protein instability and the protein loss during expression and purification involved. Here, we present a novel approach for high yield expression and purification of human TBP core (hTBPc) protein. Protein fold and activity are verified by nuclear magnetic resonance (NMR) spectroscopy and microscale thermophoresis (MST). Copyright © 2012 Elsevier Inc. All rights reserved.

    Purpose We assess the association of men's exposure to violence in childhood--witnessing physical violence against one’s mother and being hit or beaten by a parent or adult relative--with their attitudes about intimate partner violence (IPV) against women. We explore whether men’s perpetration of IPV mediates this relationship and whether men’s attitudes about IPV mediate any relationship of exposure to violence in childhood with perpetration of IPV. Methods 522 married men 18–51 years in Vietnam were interviewed. Multivariate regressions for ordinal and binary responses were estimated to assess these relationships. Results Compared to men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of reporting more reasons to hit a wife (aORs, 95%CIs: 1.43, 1.03–2.00 and 1.66, 1.05–2.64, respectively). Men’s lifetime perpetration of IPV accounted fully for these associations. Compared to men experiencing neither form of violence in childhood, men experiencing either or both had higher adjusted odds of ever perpetrating IPV (aORs, 95%CIs: 3.28, 2.15–4.99 and 4.56, 2.90–7.17, respectively). Attitudes about IPV modestly attenuated these associations. Conclusion Addressing violence in childhood is needed to change men’s risk of perpetrating IPV and greater subsequent justification of it.

    While being long in range and therefore weakly specific, electrostatic interactions are able to modulate the stability and folding landscapes of some proteins. The relevance of electrostatic forces for steering the docking of proteins to each other is widely acknowledged, however, the role of electrostatics in establishing specifically funneled landscapes and their relevance for protein structure prediction are still not clear. By introducing Debye-Hückel potentials that mimic long-range electrostatic forces into the Associative memory, Water mediated, Structure, and Energy Model (AWSEM), a transferable protein model capable of predicting tertiary structures, we assess the effects of electrostatics on the landscapes of thirteen monomeric proteins and four dimers. For the monomers, we find that adding electrostatic interactions does not improve structure prediction. Simulations of ribosomal protein S6 show, however, that folding stability depends monotonically on electrostatic strength. The trend in predicted melting temperatures of the S6 variants agrees with experimental observations. Electrostatic effects can play a range of roles in binding. The binding of the protein complex KIX-pKID is largely assisted by electrostatic interactions, which provide direct charge-charge stabilization of the native state and contribute to the funneling of the binding landscape. In contrast, for several other proteins, including the DNA-binding protein FIS, electrostatics causes frustration in the DNA-binding region, which favors its binding with DNA but not with its protein partner. This study highlights the importance of long-range electrostatics in functional responses to problems where proteins interact with their charged partners, such as DNA, RNA, as well as membranes. © 2015 The Protein Society.

    2017-08-01

    Perceived discordance of fertility desires may be more common among couples with certain sociodemographic characteristics and may lead to lower contraceptive use. Using nationally representative data from adults ages 15-49 in France in 2010, we analysed associations between sociodemographic characteristics, perceived discordance of fertility desires and contraceptive use with design-based logistic regression. Only 8% of participants perceived discordant fertility desires while 92% perceived concordance with partner fertility desire. Discordance varied by age and relationship duration and by the presence of children from previous relationships. Perceived discordance was not associated with use of a hormonal or highly effective method. Beyond own intentions, perception of a partner's fertility desires was associated with using a highly effective method among participants using any method. Engaging men and couples in family planning programmes may be important for achieving both partners' desired fertility goals.

    Accuracy of recall of the number of sexual partners individuals had over a period of one month, three months, six months and one year was studied in a group of 285 young, single, heterosexual adults. Self-reports of the number of partners were obtained on a weekly basis and then compared with recall of behavior over longer time periods that overlapped the weekly measures. For individuals who claimed abstinence or who claimed to be monogamous, accuracy of recall was relatively high, especially at the shorter time frames. Level of education was related to accuracy for claimed abstainers, such that lower levels of education were associated with lower accuracy of recall. Accuracy rates for individuals who reported having multiple sexual partners tended to be lower and were found to be related to one's propensity to engage in casual sex.

    The firms in the business environment have to choose adequate partners in order to sustain their competitive advantage and their economic performance. Plus, the creation of special communities consisting of these partners is essential for the life-long development of these latter and the firms creating them. The research project XStrat.Net aims at the identification of factors and indicators about the organizations for the modelling of intelligent agents -XStrat intelligent agents- and the engineering of a software -XStrat- to process these backbones intelligent agents. Through the use of the software, the firms will be able to select the needed partners for the creation of special communities for the purpose of learning, interest or innovation. The XStrat.Net project also intends to provide guidelines for the creation of the special communities.

    The purpose of this study was to examine alcohol use by victims and perpetrators as a risk factor for intimate partner violence and femicide. A case control design was used to describe alcohol use among Femicide/Attempted Femicide victims (n = 380), Abused Controls (n = 384) and Non-Abused Controls (n = 376), and their intimate partners. Telephone interviews of proxies (family members or friends) of femicide victims and actual survivors of attempted femicide were conducted in 10 cities. The purpose of the interviews was to gather information about relationship violence and alcohol use by femicide victims, attempted femicide survivors, and their perpetrators. Telephone interviews of controls, recruited from the same cities by random digit dialing, were also conducted. Perpetrator problem drinking was associated with an eight fold increase in partner abuse (e beta = 8.24, p femicide/attempted femicide (e beta = 2.39, p = .001), controlling for demographic differences.

  13. Polysomes of Trypanosoma brucei: Association with Initiation Factors and RNA-Binding Proteins.

    Directory of Open Access Journals (Sweden)

    Cornelia Klein

    Full Text Available We report here the results of experiments designed to identify RNA-binding proteins that might be associated with Trypanosoma brucei polysomes. After some preliminary mass spectrometry of polysomal fractions, we investigated the distributions of selected tagged proteins using sucrose gradients and immunofluorescence. As expected, the polysomal fractions contained nearly all annotated ribosomal proteins, the translation-associated protein folding complex, and many translation factors, but also many other abundant proteins. Results suggested that cap-binding proteins EIF4E3 and EIF4E4 were associated with both free and membrane-bound polysomes. The EIF4E binding partners EIF4G4 and EIF4G3 were present but the other EIF4E and EIF4G paralogues were not detected. The dominant EIF4E in the polysomal fraction is EIF4E4 and very few polysomal mRNAs are associated with EIF4G. Thirteen potential mRNA-binding proteins were detected in the polysomes, including the known polysome-associated protein RBP42. The locations of two of the other proteins were tested after epitope tagging: RBP29 was in the nucleus and ZC3H29 was in the cytoplasm. Quantitative analyses showed that specific association of an RNA-binding protein with the polysome fraction in sucrose gradients will not be detected if the protein is in more than 25-fold molar excess over its target binding sites.

    Full Text Available Transcription factors have traditionally been viewed with skepticism as viable drug targets, but they offer the potential for completely novel mechanisms of action that could more effectively address the stem cell like properties, such as self-renewal and chemo-resistance, that lead to the failure of traditional chemotherapy approaches. Core binding factor is a heterodimeric transcription factor comprised of one of 3 RUNX proteins (RUNX1-3 and a CBFβ binding partner. CBFβ enhances DNA binding of RUNX subunits by relieving auto-inhibition. Both RUNX1 and CBFβ are frequently mutated in human leukemia. More recently, RUNX proteins have been shown to be key players in epithelial cancers, suggesting the targeting of this pathway could have broad utility. In order to test this, we developed small molecules which bind to CBFβ and inhibit its binding to RUNX. Treatment with these inhibitors reduces binding of RUNX1 to target genes, alters the expression of RUNX1 target genes, and impacts cell survival and differentiation. These inhibitors show efficacy against leukemia cells as well as basal-like (triple-negative breast cancer cells. These inhibitors provide effective tools to probe the utility of targeting RUNX transcription factor function in other cancers.

    Collaboration in international nursing student placements requires equitable partnerships between global partners to address areas of shared importance, such as equity and justice in health promotion. This qualitative study was the first to use the Leffers and Mitchell Conceptual Model for Partnership and Sustainability in Global Health to elicit global host partners' perspectives regarding effective collaboration for Canadian community health nursing placements in the Dominican Republic. Focus group and semi-structured interview methodology was conducted with Dominican Republic (Dominican and Haitian) host partners (n = 23) about the engagement processes and host partner factors for effective partnership. Dominican (83%) and Haitian (17%) participants, comprised similar numbers of male and female adults aged 18-60 years (mean age = 36 years), represented the full range of the Dominican Republic host partners (e.g., teachers, health professionals). Interpretive analysis revealed themes that included (1) the unique role of the cultural broker; (2) relational collaboration in a collective society; (3) reciprocal approaches that honor local expertise; and (4) contextual socioeconomic and cultural factors that influence partnerships. Future research and implications at the individual, community, and policy levels are discussed. © 2016 Wiley Periodicals, Inc.

  16. Men who batter intimate partners: a grounded theory study of the development of male violence in intimate partner relationships.

    Tilley, Donna Scott; Brackley, Margaret

    2005-04-01

    Intimate partner violence is a serious and pervasive problem in U.S. society, with 25% of women and 7.6% of men reporting physical abuse by an intimate partner each year. Understanding the risk factors for development of violence is essential toward the development of interventions to reduce partner violence. Much of the understanding about the development of partner violence is based on research with victims rather than perpetrators. The study was conducted with men convicted of assault on an intimate female partner. Grounded theory was the method used to analyze data from interviews with 16 men participating in a batterers' intervention and prevention program. From the data, the Violent Couples Model was developed. The primary elements of the Violent Couples Model are justifying violence, minimizing violence, childhood exposure to violence, ineffective anger management, childhood experience of violence, and ineffective conflict resolution. Social and familial factors serve as moderating elements. Contextual elements of the model include power and control, social isolation, desensitization, insecure maternal relationships, the view of violence as a private problem, ambivalent intimate relationships, objectification of women, immaturity, lack of awareness about what constitutes violence, mistrust, traditional views of the roles of women, financial issues, and jealousy. Interventions indicated in the model are primary, or preventive, in nature. The model focuses on prevention efforts with the family as a whole, rather than on batterers alone.

  17. Intimate partner violence and incidence of common mental disorder

    Directory of Open Access Journals (Sweden)

    Marcela Franklin Salvador de Mendonça

    Full Text Available ABSTRACT OBJECTIVE To investigate the association of intimate partner violence against women reported in the last 12 months and seven years with the incidence of common mental disorders. METHODS A prospective cohort study with 390 women from 18 to 49 years, registered in the Family Health Program of the city of Recife, State of Pernambuco; from July 2013 to December 2014. The Self Reporting Questionnaire-20 (SRQ-20 assessed mental health. Intimate partner violence consists of concrete acts of psychological, physical or sexual violence that the partner inflicts on the woman. Poisson regression was used to estimate crude and adjusted relative risks (RR of the association between common mental disorders and intimate partner violence. RESULTS The incidence of common mental disorders was 44.6% among women who reported intimate partner violence in the last 12 months and 43.4% among those who reported in the past seven years. Mental disorders remained associated with psychological violence (RR = 3.0; 95%CI 1.9–4.7 and RR = 1.8; 95%CI 1.0–3.7 in the last 12 months, and seven years, respectively, even in the absence of physical or sexual violence. When psychological violence were related to physical or sexual violence, the risk of common mental disorders was even higher, both in the last 12 months (RR = 3.1; 95%CI 2.1–4.7 and in the last seven years (RR = 2.5; 95%CI 1.7–3.8. CONCLUSIONS Intimate partner violence is associated with the incidence of common mental disorders in women. The treatment of the consequences of IPV and support for women in seeking protection for themselves for public services is essential.

    This qualitative focuses on the personal experiences of partners to a spinal cord injured person. Using a Ricoeurian phenomenological-hermeneutic approach, we analysed seven partners' narratives 1 and 2 years after their partner's injury. The study revealed how the injury was experienced from...... the partners' perspective through the aftermath. In the acute phase after the injury, partners also felt harmed, and support was needed in relation to their own daily activities, eating, resting, and managing distress. During the institutionalized rehabilitation, partners felt torn between supporting...... the injured partner and the demanding tasks of everyday life outside the institution. After discharge, partners struggled for the injured partner to regain a well-functioning everyday life and for reestablishing life as a couple. The partner struggled to manage the overwhelming amount of everyday tasks. Some...

    Intimate partner violence is a significant health problem for women, with consequences extending to work as well as society at large. This article describes workplace interference tactics, how women cope with violence at work, and workplace supports for a sample of recently employed women with domestic violence orders (DVO; n = 518). Results indicate that violent partners used a wide range of work interference tactics, that women were more likely to tell someone at work about the victimization than they were to hide the information, and that coworkers and supervisors provided a range of supports to women who did disclose their situation. Implications for further research and practice are discussed.

    Pregnant and parenting teens suffer higher rates of intimate partner violence (IPV) than older mothers. This qualitative metasynthesis explores teen mothers' experience with IPV during pregnancy and postpartum. Organized by the metaphor of a web, findings highlight how pervasive violence during childhood contributes to teen pregnancy and the risk of IPV as violence is normalized. The web constricts through the partner's control as violence emerges or worsens with pregnancy. Young mothers become increasingly isolated, and live with the physical and psychological consequences of IPV. Trauma-informed nursing practice is needed to support teen mothers in violent intimate relationships to spin a new web.

    We examined the association between neighborhood-level factors and intimate partner femicide (IPF) using Wisconsin Violent Death Reporting System (WVDRS) data and Wisconsin Coalition Against Domestic Violence (WCADV) reports, in concert with neighborhood-level information. After controlling for individual characteristics, neighborhood-level disadvantage was associated with a decreased likelihood of IPF status, as compared with other femicides, whereas neighborhood-level residential instability was associated with an increased likelihood of IPF status. Neighborhood plays a role in differentiating IPFs from other femicides in our study area. Our findings demonstrate the importance of multilevel strategies for understanding and reducing the burden of intimate partner violence. © The Author(s) 2014.

    2013-09-01

    The present paper is an ode to a classic citation by Benet and Hoener (2002. Clin Pharm Ther 71(3):115-121). The now classic paper had a huge impact on drug development and the way the issue of protein binding is perceived and interpreted. Although the authors very clearly pointed out the limitations and underlying assumptions for their delineations, these are too often overlooked and the classic paper's message is misinterpreted by broadening to cases that were not intended. Some members of the scientific community concluded from the paper that protein binding is not important. This was clearly not intended by the authors, as they finished their paper with a paragraph entitled: "When is protein binding important?" Misinterpretation of the underlying assumptions in the classic work can result in major pitfalls in drug development. Therefore, we revisit the topic of protein binding with the intention of clarifying when clinically relevant changes should be considered during drug development.

    G protein coupled receptors (GPCRs) are key players in signal recognition and cellular communication making them important therapeutic targets. Large-scale production of these membrane proteins in their native form is crucial for understanding their mechanism of action and target-based drug design. Here we report the overexpression system for a GPCR, the cannabinoid receptor subtype 2 (CB2), in Escherichia coli C43(DE3) facilitated by two fusion partners: Mistic, an integral membrane protein expression enhancer at the N-terminal, and TarCF, a C-terminal fragment of the bacterial chemosensory transducer Tar at the C-terminal of the CB2 open reading frame region. Multiple histidine tags were added on both ends of the fusion protein to facilitate purification. Using individual and combined fusion partners, we found that CB2 fusion protein expression was maximized only when both partners were used. Variable growth and induction conditions were conducted to determine and optimize protein expression. More importantly, this fusion protein Mistic-CB2-TarCF can localize into the E. coli membrane and exhibit functional binding activities with known CB2 ligands including CP55,940, WIN55,212-2 and SR144,528. These results indicate that this novel expression and purification system provides us with a promising strategy for the preparation of biologically active GPCRs, as well as general application for the preparation of membrane-bound proteins using the two new fusion partners described.

    2013-09-01

    Alcohol use is prevalent among college students, including those who are in committed romantic relationships. Individuals' perceptions of their partner's alcohol use may have significant effects on how they view both their partner and their relationship. The current study examines the effect of one's perception of one's romantic partner's drinking as problematic on one's relationship satisfaction and commitment, and whether this varies as a function of one's partner's drinking. Both partners in romantic heterosexual relationships (N = 78 dyads) completed an online survey assessing alcohol use and problems, relationship satisfaction and commitment, and the perception that their partner's drinking was problematic. Analyses using Actor-Partner Interdependence Models (APIMs) revealed a partner-moderated actor interaction, such that partner self-reported drinking significantly moderated the association between the actor's perception of their partner's drinking as problematic and actor relationship outcomes. Results indicated that when partners drank at higher levels, perceiving their drinking as problematic did not have an effect. These individuals were less satisfied regardless of their perceptions. However, when partners drank at lower levels, perceiving their drinking as problematic was negatively associated with relationship outcomes. Furthermore, for alcohol consumption, three-way interactions with gender emerged, indicating that this effect was stronger for males. Results extend the literature on drinking in relationships and on interpersonal perception. Implications and future directions are discussed.

    2013-10-01

    Twenty-three studies identified from a previous systematic review examining the effects of communication partner training on persons with aphasia and their communication partners were evaluated for methodological quality. Two reviewers rated the studies on defined methodological quality criteria relevant to each study design. There were 11 group studies, seven single-subject participant design studies, and five qualitative studies. Quality scores were derived for each study. The mean inter-rater reliability of scores for each study design ranged from 85-93%, with Cohen's Kappa indicating substantial agreement between raters. Methodological quality of research on communication partner training in aphasia was highly varied. Overall, group studies employed the least rigorous methodology as compared to single subject and qualitative research. Only two of 11 group studies complied with more than half of the quality criteria. No group studies reported therapist blinding and only one group study reported participant blinding. Across all types of studies, the criterion of treatment fidelity was most commonly omitted. Failure to explicitly report certain methodological quality criteria may account for low ratings. Using methodological rating scales specific to the type of study design may help improve the methodological quality of aphasia treatment studies, including those on communication partner training.

    2010-01-01

    This study aims to carry out an economic evaluation of intimate partner violence in France. Using published data, institutional sources, field studies and expert opinions, the cost of intimate partner violence is estimated in terms of the overall cost to society. A range of different economic approaches are used (micro-economic, meso-economic and macro-economic approaches). The total cost of intimate partner violence in France is estimated at 2.5 billion Euros per year (between 1.7 and 3.5 billion Euros). The total cost of intimate partner violence includes healthcare costs (483 ? million), social and justice services (355 ? million), production losses as a result of deaths, imprisonments and absenteeism (1099 ? million), and the human costs of rape and prejudice (535 ? million). By increasing the budget allocated to the prevention of domestic violence by one euro, it is estimated that the state, health insurance and local authorities could make savings of up to 87 Euros of social spending, including 30 Euros of direct expenses.

Instead, they must understand--and guide--the complex emotional transformation that every "partner hopeful" must go through.…

  6. Exploring Social Markets, Partner Debt, and Mimetic Currency in Dolphins

    Directory of Open Access Journals (Sweden)

    Christine M. Johnson

    2016-11-01

    Full Text Available Dynamic models of “Biological Markets” can provide a systematic and ecologically-valid approach to studying communication and social cognition in dolphins. These market models view interacting animals as traders engaged in a negotiation for social commodities, whose values vary with the state of their current market. Across the phyla, factors like the supply and demand of social resources can impact on investment and partner choice. Such models map well to the polyadic nature of typical social interactions, generating predictions based on configurations of participants, and enabling us to use behavioral observations to address issues of cognitive organization. Plus, by positing communicative signals as social currency, these models provide tools to discern which aspects of dolphins’ vocal and gestural repertoires impact on their social relationships. Adapting these models for dolphins highlights the premise that “partnerhood is good,” wherein both players gain when they partner. When considered over time, the gains and losses of valued partners may accumulate into “wealth” or “debt” for a particular player, altering its threshold for responding to its market’s odds. For example, “Partner Debt” could motivate a player to more readily take action to destabilize its current market. In dolphins, one type of social currency that bears further investigation is the use of vocal and/or gestural mimicry. Such mimesis may promote prosociality, cooperation, and even the coordination of third party information.

  9. Friendship-based partner switching promotes cooperation in heterogeneous populations

    2016-02-01

    The forming of human social ties tends to be with similar individuals. This study concentrates on the emergence of cooperation among heterogeneous populations. A simple model is proposed by considering the impact of interplay between the evolution of strategies and that of social partnerships on cooperation dynamics. Whenever two individuals acquire the rewards by playing prisoner's dilemma game with each other, the friendship (friendship is quantified as the weight of a link) between the two individuals deepens. Individuals can switch off the social ties with the partners who are unfriendly and rewire to similar new ones. Under this partner switching mechanism, population structure is divided into several groups and cooperation can prevail. It is observed that the frequent tendency of partner switching can lead to the enhancement of cooperative behavior under the enormous temptation to defect. Moreover, the influence of discounting the relationship between different individuals is also investigated. Meanwhile, the cooperation prevails when the adjustment of friendships mainly depends on the incomes of selected individuals rather than that of their partners. Finally, it is found that too similar population fail to maximize the cooperation and there exists a moderate similarity that can optimize cooperation.

    Delaunay, Cédric; Gonzalez-Fraile, J; Lee, Seung J; Panico, Giuliano; Perez, Gilad

    2014-01-01

    We study the implications of a large degree of compositeness for the light generation quarks in composite pseudo-Nambu-Goldstone-boson Higgs models. We focus in particular on viable scenarios where the right-handed up-type quarks have a sizable mixing with the strong dynamics. For concreteness we assume the latter to be characterized by an SO(5)/SO(4) symmetry with fermionic resonances in the SO(4) singlet and fourplet representations. Singlet partners dominantly decay to a Higgs boson and jets. As no dedicated searches are currently looking for these final states, singlet partners can still be rather light. Conversely, some fourplet partners dominantly decay to an electroweak gauge boson and a jet, a signature which has been analyzed at the LHC. To constrain the parameter space of this scenario we have reinterpreted various LHC analyses. In the limit of first two generation degeneracy, as in minimal flavor violation or U(2)-symmetric flavor models, fourplet partners need to be relatively heavy, with masses a...

  19. Ravens reconcile after aggressive conflicts with valuable partners.

    Directory of Open Access Journals (Sweden)

    Orlaith N Fraser

    Full Text Available Reconciliation, a post-conflict affiliative interaction between former opponents, is an important mechanism for reducing the costs of aggressive conflict in primates and some other mammals as it may repair the opponents' relationship and reduce post-conflict distress. Opponents who share a valuable relationship are expected to be more likely to reconcile as for such partners the benefits of relationship repair should outweigh the risk of renewed aggression. In birds, however, post-conflict behavior has thus far been marked by an apparent absence of reconciliation, suggested to result either from differing avian and mammalian strategies or because birds may not share valuable relationships with partners with whom they engage in aggressive conflict. Here, we demonstrate the occurrence of reconciliation in a group of captive subadult ravens (Corvus corax and show that it is more likely to occur after conflicts between partners who share a valuable relationship. Furthermore, former opponents were less likely to engage in renewed aggression following reconciliation, suggesting that reconciliation repairs damage caused to their relationship by the preceding conflict. Our findings suggest not only that primate-like valuable relationships exist outside the pair bond in birds, but that such partners may employ the same mechanisms in birds as in primates to ensure that the benefits afforded by their relationships are maintained even when conflicts of interest escalate into aggression. These results provide further support for a convergent evolution of social strategies in avian and mammalian species.

    Valerie J. Young

    2017-02-01

    Full Text Available Background This study merges two theoretical paradigms: self-determination theory and interdependence theory. The primary objective was to examine whether people in relationships are motivated to enact healthy or unhealthy behaviors based on personal (i.e., autonomous or interpersonal (controlled motives. Participants and procedure We tested the sources of healthy and unhealthy motivation in a cross-sectional, dyadic survey, collecting data from 243 couples in romantic relationships. Survey items assessed sources of healthy and unhealthy motivational influence, including the self, partner, and relationship, in conjunction with relationship satisfaction and well-being. Data were analyzed according to the Actor Partner Interdependence Model to examine intrapersonal and interpersonal associations between variables. Results Healthy and unhealthy behavior motivation appears to be a relational, rather than individual construct. Partner healthy motivation was positively associated with individuals’ relationship satisfaction. For individuals who reported more unhealthy relationship motivations, relationship satisfaction and well-being were lower. There were no significant associations for self motivations. Conclusions The findings suggest that relational partners and the romantic relationship itself are important in understanding the dimensions of health motivation for people in relationships. We conclude that the romantic relationship context impacts health maintenance, supporting the merging of personal and interpersonal motivations for health behaviors.

    Full Text Available Introduction: Natural orifice transluminal endoscopic surgery (NOTES transvaginal cholecystectomy is being intensivelystudied. A few studies have been recently published evaluating patients’ attitude towards NOTES with its individualaccesses. However, the choice of a transvaginal access with its potential influence on sex life and fertility is notrestricted entirely to women. The sexual partner would at least give his opinion or decide together with the woman. Aim: The aim of the study was to assess the attitude of male sexual partners of potential NOTES transvaginal patientstowards the surgical access. Material and methods: Hundred males were asked for their opinion in a specially designed instrument. Results: The general attitude of male sexual partners of potential NOTES transvaginal cholecystectomy patients isnegative. With several possible problems and complications feared by the partners, they would mostly oppose or dissuadeagainst NOTES transvaginal cholecystectomy. The cosmetic benefit seems not to justify undergoing a noveltyprocedure with potential complications threatening sexual life and procreation. This attitude was especially observedin young, sexually active males with high appreciation of sexual life. Conclusions: Both scientific and educational efforts are required to prove safety and efficiency of NOTES transvaginalcholecystectomy beyond question.

  11. Partner Choice Drives the Evolution of Cooperation via Indirect Reciprocity.

    Directory of Open Access Journals (Sweden)

    Gilbert Roberts

    Full Text Available Indirect reciprocity potentially provides an important means for generating cooperation based on helping those who help others. However, the use of 'image scores' to summarize individuals' past behaviour presents a dilemma: individuals withholding help from those of low image score harm their own reputation, yet giving to defectors erodes cooperation. Explaining how indirect reciprocity could evolve has therefore remained problematic. In all previous treatments of indirect reciprocity, individuals are assigned potential recipients and decide whether to cooperate or defect based on their reputation. A second way of achieving discrimination is through partner choice, which should enable individuals to avoid defectors. Here, I develop a model in which individuals choose to donate to anyone within their group, or to none. Whereas image scoring with random pairing produces cycles of cooperation and defection, with partner choice there is almost maximal cooperation. In contrast to image scoring with random pairing, partner choice results in almost perfect contingency, producing the correlation between giving and receiving required for cooperation. In this way, partner choice facilitates much higher and more stable levels of cooperation through image scoring than previously reported and provides a simple mechanism through which systems of helping those who help others can work.

    Entem, D.R.; Fernandez, F.

    2016-05-25

    Since the discovery of the $X(3872)$ the study of heavy meson molecules has been the subject of many investigations. On the experimental side different experiments have looked for its spin partners and the bottom analogs. On the theoretical side different approaches have been used to understand this state. Some of them are EFT that impose HQSS and so they make predictions for the partners of the $X(3872)$, suggesting the existence of a $J^{PC}=2^{++}$ partner in the charm sector or $J^{PC}=1^{++}$ or $2^{++}$ analogs in the bottom. In our work, in order to understand the $X(3872)$, we use a Chiral quark model in which, due to the proximity to the $DD^*$ threshold, we include $c\\bar c$ states coupled to $DD^*$ molecular components. In this coupled channel model the relative position of the bare $c\\bar c$ states with two meson thresholds are very important. We have looked for the $X(3872)$ partners and we don't find a bound state in the $D^*D^*$ $J^{PC}=2^{++}$. In the bottom sector we find the opposite situati...

    2005-12-01

    Partner violence is a serious public health problem affecting mostly women. This qualitative study assessed the perceptions of rural Igbo women of Nigeria of intimate partner violence. Information was elicited using in-depth interviews and focus group discussion. Women of childbearing age were selected from the various women age grades in Ozubulu, Anambra State, Nigeria. Findings revealed that the women generally condone and are complacent with intimate partner violence, perceiving it as cultural and religious norms. The women felt that reprimands, beating and forced sex affecting their physical, mental and reproductive wellbeing are normal in marriage. They did not support reporting such cases to the police or divorcing the man, they would rather prefer reporting to family members. They felt that exiting the marriage would not gain the support of family members. They also expressed fear for the uncertainty in re-marrying, means of livelihood after re-marriage, social stigmatisation, and concern for their children. Socio-cultural norms and structures favour partner violence in Anambra State of Nigeria. There is a need for advocacy and concerted action that will involve the educational, health, civil and religious sectors of the society to evolve sustainable structures that will empower women and provide support to enable victims to react appropriately to violence.
