    June, Audrey Williams

    2006-01-01

    A key part of the compensation package for some college and university presidents is money that they do not receive in their paychecks. Formally known as deferred compensation, such payments can take many forms, including supplemental retirement pay, severance pay, or even bonuses. With large institutions leading the way, deferred compensation has…

    We introduce deferred warping, a novel approach for real-time deformation of 3D objects attached to an animated or manipulated surface. Our target application is virtual prototyping of garments where 2D pattern modeling is combined with 3D garment simulation which allows an immediate validation of the design. The technique works in two steps: First, the surface deformation of the target object is determined and the resulting transformation field is stored as a matrix texture. Then the matrix texture is used as look-up table to transform a given geometry onto a deformed surface. Splitting the process in two steps yields a large flexibility since different attachment types can be realized by simply defining specific mapping functions. Our technique can directly handle complex topology changes within the surface. We demonstrate a fast implementation in the vertex shading stage allowing the use of highly decorated surfaces with millions of triangles in real-time.

  4. DEFERRED TAXES: FEATURES OF ACCOUNTING AND ANALYSIS IN AGRICULTURAL ORGANIZATIONS

    2016-04-01

    Full Text Available The article highlights the results of the analysis of deferred taxes as indicators of the accounting financial statements, reflecting payments to the budget for income tax agricultural organizations. The importance of deferred tax assets and deferred tax liabilities as a key marker of efficiency of the tax policy of the agricultural organizations is emphasized. Its inefficiency can be judge by excess of deferred tax assets over deferred tax liabilities, which is seen as a temporary diversion of funds from the market, which has zero profitability. The conclusion was made about the improvement of financial stability and liquidity of the organization under the influence of deferred tax liabilities and the deteriorating financial situation, financial stability and liquidity under the influence of deferred tax assets. The effective income tax rate of the agricultural organizations of Krasnodar territory is determined; it does not exceed 3% and differs from general because of tax benefits, deductions and tax policy. The basic causes of appearance of temporary differences are identified by types in the account of the agricultural organizations. Typical errors in accounting for deferred taxes are described. A refined form of the report on financial results containing transcript of profit before tax from non-agricultural activities, with the aim of monitoring the relationship of accounting and taxable profit in the agricultural organizations

    The loss or mutilation of a breast as a result of surgical treatment of neoplastic disease always represents a negative impact on a woman's psyche and negatively influences the quality of the woman's remaining life. The goal of our work was to implement deferred breast reconstruction into routine practice and the objectification of the influence of reconstruction on bodily integrity, quality of life, and the feeling of satisfaction in women. Women in remission from neoplastic disease after a radical mastectomy were indicated for breast reconstruction. Between January 2002 and December 2011 deferred breast reconstruction was carried out 174 × on 163 women, with an average age of 49.2 and an age range of 29-67 years. The most frequently used reconstruction method was a simple gel augmentation of the breast or a Becker expander/implant - 51 (29.3%) and 37 (21.3%), or in combination with a lateral thoracodorsal flap (31; 17.8% and 47; 27%); reconstruction using a free DIEP flap was carried out 7 × (4%). Complications occurred in 19 operations (10.9%) with a dominance of inflammation and pericapsular fibrosis, in a subjective analysis, satisfaction with the results prevailed, along with an increased quality of life after reconstruction. A growing number of deferred breast reconstructions, women's satisfaction with the results, the positive influence of renewed bodily integrity on the feeling of life satisfaction and the quality of life have elevated breast reconstructions to a qualitatively higher level.

  10. How to avoid deferred-compensation troubles.

    Science.gov (United States)

    Freeman, Todd I

    2005-06-01

    Executive compensation packages have long included stock options and deferred compensation plans in order to compete for talent. Last year, Congress passed a law in response to the Enron debacle, in which executives were perceived to be protecting their deferred compensation at the expense of employees, creditors, and investors. The new law is designed to protect companies and their shareholders from being raided by the very executives that guided the company to financial ruin. Physicians who are part owners of medical practices need to know about the changes in the law regarding deferred compensation and how to avoid costly tax penalties. This article discusses how the changes affect medical practices as well as steps physician-owned clinics can take to avoid the risk of penalty, such as freezing deferred compensation and creating a new deferred compensation plan.

  11. HIV Rev Assembly on the Rev Response Element (RRE: A Structural Perspective

    Directory of Open Access Journals (Sweden)

    Jason W. Rausch

    2015-06-01

    Full Text Available HIV-1 Rev is an ~13 kD accessory protein expressed during the early stage of virus replication. After translation, Rev enters the nucleus and binds the Rev response element (RRE, a ~350 nucleotide, highly structured element embedded in the env gene in unspliced and singly spliced viral RNA transcripts. Rev-RNA assemblies subsequently recruit Crm1 and other cellular proteins to form larger complexes that are exported from the nucleus. Once in the cytoplasm, the complexes dissociate and unspliced and singly-spliced viral RNAs are packaged into nascent virions or translated into viral structural proteins and enzymes, respectively. Rev binding to the RRE is a complex process, as multiple copies of the protein assemble on the RNA in a coordinated fashion via a series of Rev-Rev and Rev-RNA interactions. Our understanding of the nature of these interactions has been greatly advanced by recent studies using X-ray crystallography, small angle X-ray scattering (SAXS and single particle electron microscopy as well as biochemical and genetic methodologies. These advances are discussed in detail in this review, along with perspectives on development of antiviral therapies targeting the HIV-1 RRE.

  13. Pulsed feedback defers cellular differentiation.

    Directory of Open Access Journals (Sweden)

    Joe H Levine

    2012-01-01

    Full Text Available Environmental signals induce diverse cellular differentiation programs. In certain systems, cells defer differentiation for extended time periods after the signal appears, proliferating through multiple rounds of cell division before committing to a new fate. How can cells set a deferral time much longer than the cell cycle? Here we study Bacillus subtilis cells that respond to sudden nutrient limitation with multiple rounds of growth and division before differentiating into spores. A well-characterized genetic circuit controls the concentration and phosphorylation of the master regulator Spo0A, which rises to a critical concentration to initiate sporulation. However, it remains unclear how this circuit enables cells to defer sporulation for multiple cell cycles. Using quantitative time-lapse fluorescence microscopy of Spo0A dynamics in individual cells, we observed pulses of Spo0A phosphorylation at a characteristic cell cycle phase. Pulse amplitudes grew systematically and cell-autonomously over multiple cell cycles leading up to sporulation. This pulse growth required a key positive feedback loop involving the sporulation kinases, without which the deferral of sporulation became ultrasensitive to kinase expression. Thus, deferral is controlled by a pulsed positive feedback loop in which kinase expression is activated by pulses of Spo0A phosphorylation. This pulsed positive feedback architecture provides a more robust mechanism for setting deferral times than constitutive kinase expression. Finally, using mathematical modeling, we show how pulsing and time delays together enable "polyphasic" positive feedback, in which different parts of a feedback loop are active at different times. Polyphasic feedback can enable more accurate tuning of long deferral times. Together, these results suggest that Bacillus subtilis uses a pulsed positive feedback loop to implement a "timer" that operates over timescales much longer than a cell cycle.

  15. Thermodynamics of Rev-RNA interactions in HIV-1 Rev-RRE assembly.

    Science.gov (United States)

    Jayaraman, Bhargavi; Mavor, David; Gross, John D; Frankel, Alan D

    2015-10-27

    The HIV-1 protein Rev facilitates the nuclear export of intron-containing viral mRNAs by recognizing a structured RNA site, the Rev-response-element (RRE), contained in an intron. Rev assembles as a homo-oligomer on the RRE using its α-helical arginine-rich-motif (ARM) for RNA recognition. One unique feature of this assembly is the repeated use of the ARM from individual Rev subunits to contact distinct parts of the RRE in different binding modes. How the individual interactions differ and how they contribute toward forming a functional complex is poorly understood. Here we examine the thermodynamics of Rev-ARM peptide binding to two sites, RRE stem IIB, the high-affinity site that nucleates Rev assembly, and stem IA, a potential intermediate site during assembly, using NMR spectroscopy and isothermal titration calorimetry (ITC). NMR data indicate that the Rev-IIB complex forms a stable interface, whereas the Rev-IA interface is highly dynamic. ITC studies show that both interactions are enthalpy-driven, with binding to IIB being 20-30 fold tighter than to IA. Salt-dependent decreases in affinity were similar at both sites and predominantly enthalpic in nature, reflecting the roles of electrostatic interactions with arginines. However, the two interactions display strikingly different partitioning between enthalpy and entropy components, correlating well with the NMR observations. Our results illustrate how the variation in binding modes to different RRE target sites may influence the stability or order of Rev-RRE assembly and disassembly, and consequently its function.

  8. Analysis of the virulence-associated RevSR two-component signal transduction system of Clostridium perfringens.

    Science.gov (United States)

    Cheung, Jackie K; Wisniewski, Jessica A; Adams, Vicki M; Quinsey, Noelene S; Rood, Julian I

    2016-09-01

    Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that causes human gas gangrene (clostridial myonecrosis) and food poisoning. Early studies showed that virulence was regulated by the VirSR two-component signal transduction system. However, our identification of the RevR orphan response regulator indicated that more than one system was involved in controlling virulence. To further characterize this virulence-associated regulator, gel mobility shift experiments, coupled with DNase I footprinting, were used to identify the RevR DNA binding sequence. Bioinformatics analysis suggested that an orphan sensor histidine kinase, CPE1757 (renamed RevS), was the cognate sensor of RevR. Interaction between RevS and RevR was demonstrated by use of a bacterial two-hybrid system and validated by protein-protein interaction studies using biolayer interferometry. To assess the involvement of RevS in virulence regulation, the revS gene was inactivated by Targetron insertion. When isogenic wild-type, revS and complemented revS strains were tested in a mouse myonecrosis model, the revS mutant was found to be attenuated in virulence, which was similar to the attenuation observed previously with the revR mutant. However, transcriptional analysis of selected RevR-regulated genes in the revS mutant revealed a different pattern of expression to a revR mutant, suggesting that the RevSR system is more complex than originally thought. Taken together, the results have led to the identification and characterization of the two essential parts of a new regulatory network that is involved in the regulation of virulence in C. perfringens.

  10. Nuclear Export Signal Masking Regulates HIV-1 Rev Trafficking and Viral RNA Nuclear Export.

    Science.gov (United States)

    Behrens, Ryan T; Aligeti, Mounavya; Pocock, Ginger M; Higgins, Christina A; Sherer, Nathan M

    2017-02-01

    HIV-1's Rev protein forms a homo-oligomeric adaptor complex linking viral RNAs to the cellular CRM1/Ran-GTP nuclear export machinery through the activity of Rev's prototypical leucine-rich nuclear export signal (NES). In this study, we used a functional fluorescently tagged Rev fusion protein as a platform to study the effects of modulating Rev NES identity, number, position, or strength on Rev subcellular trafficking, viral RNA nuclear export, and infectious virion production. We found that Rev activity was remarkably tolerant of diverse NES sequences, including supraphysiological NES (SNES) peptides that otherwise arrest CRM1 transport complexes at nuclear pores. Rev's ability to tolerate a SNES was both position and multimerization dependent, an observation consistent with a model wherein Rev self-association acts to transiently mask the NES peptide(s), thereby biasing Rev's trafficking into the nucleus. Combined imaging and functional assays also indicated that NES masking underpins Rev's well-known tendency to accumulate at the nucleolus, as well as Rev's capacity to activate optimal levels of late viral gene expression. We propose that Rev multimerization and NES masking regulates Rev's trafficking to and retention within the nucleus even prior to RNA binding.

  11. Deferred Executive Compensation Policies in Chinese State-owned Enterprises

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Since the commencement of industrial reform in China, most Chinese state-owned enterprises have adopted a deferred executive compensation policy to provide incentives for their management teams. However, the effectiveness of such a policy needs to be evaluated In this paper, we specify a model of deferred executive compensation policy, in which the compensation for executives is contingent on firms 'future revenue. The model suggests that under deferred executive compensation policies, managers exhibit an increasing level of effort in every period. Furthermore, the deferred compensation policy encourages managers to make long-term investments, which might generate revenue even after the termination of managerial contracts.

  14. Seduction trauma: representation, deferred action, and pathogenic development.

    Science.gov (United States)

    Blum, H P

    1996-01-01

    Seduction trauma refers to a range of phenomena currently described under the rubric of child abuse. Freud elucidated the fantasy distortion and elaboration of traumatic experience and retained the importance of actual trauma. Psychic trauma is associated with the alteration of self and object representations and ensuing new identifications, e.g., with victim and aggressor. The "deferred action" of psychic trauma is an antiquated concept and psychic trauma has immediate effects as well as far reaching developmental consequences. Prior trauma predisposes to later traumatic vulnerability and to trauma linked to phase specific unconscious conflict. The pathogenesis of child sex abuse and the enactment of oedipal incest extends before and after the oedipal phase, is often associated with other forms of abuse, and has a history of pathogenic parent-child relationship.

  15. Mixed-Precision Spectral Deferred Correction: Preprint

    2015-09-02

    Convergence of spectral deferred correction (SDC), where low-order time integration methods are used to construct higher-order methods through iterative refinement, can be accelerated in terms of computational effort by using mixed-precision methods. Using ideas from multi-level SDC (in turn based on FAS multigrid ideas), some of the SDC correction sweeps can use function values computed in reduced precision without adversely impacting the accuracy of the final solution. This is particularly beneficial for the performance of combustion solvers such as S3D [6] which require double precision accuracy but are performance limited by the cost of data motion.

    Minion, Michael L.

    2002-10-06

    A semi-implicit formulation of the method of spectral deferred corrections (SISDC) for ordinary differential equations with both stiff and non-stiff terms is presented. Several modifications and variations to the original spectral deferred corrections method by Dutt, Greengard, and Rokhlin concerning the choice of integration points and the form of the correction iteration are presented. The stability and accuracy of the resulting ODE methods are explored analytically and numerically. The SISDC methods are intended to be combined with the method of lines approach to yield a flexible framework for creating higher-order semi-implicit methods for partial differential equations. A discussion and numerical examples of the SISDC method applied to advection-diffusion type equations are included. The results suggest that higher-order SISDC methods are more efficient than semi-implicit Runge-Kutta methods for moderately stiff problems in terms of accuracy per function evaluation.

    Full Text Available Flow-through model of income tax reporting in general purpose financial statements had a long history of use in Serbia. It was only in 2004 (and 2003 for banks, when the implementation of deferred taxes model started. It was inevitable, because IAS/IFRS became mandatory basis for preparing financial statements. In this paper we examine quality of deferred taxes disclosures in the financial statements of companies in Serbia. We also documented the most common temporary differences that arise in measuring accounting and taxable income and in that way we identified the major sources of deferred tax. We analyzed the materiality of deferred taxes and their effect on company´s performance in Serbia.

    2014-08-27

    HIV replication requires nuclear export of unspliced and singly spliced viral transcripts. Although a unique RNA structure has been proposed for the Rev-response element (RRE) responsible for viral mRNA export, how it recruits multiple HIV Rev proteins to form an export complex has been unclear. We show here that initial binding of Rev to the RRE triggers RNA tertiary structural changes, enabling further Rev binding and the rapid formation of a viral export complex. Analysis of the Rev-RRE assembly pathway using SHAPE-Seq and small-angle X-ray scattering (SAXS) reveals two major steps of Rev-RRE complex formation, beginning with rapid Rev binding to a pre-organized region presenting multiple Rev binding sites. This step induces long-range remodeling of the RNA to expose a cryptic Rev binding site, enabling rapid assembly of additional Rev proteins into the RNA export complex. This kinetic pathway may help maintain the balance between viral replication and maturation.DOI: http://dx.doi.org/10.7554/eLife.03656.001.

    Although lesions deferred revascularization following fractional flow reserve (FFR) assessment have a low risk of adverse cardiac events, variability in risk for deferred lesion intervention (DLI) has not been previously evaluated. The aim of this study was to develop a prediction model to estimate 1-year risk of DLI for coronary lesions where revascularization was not performed following FFR assessment. A prediction model for DLI was developed from a cohort of 721 patients with 882 coronary lesions where revascularization was deferred based on FFR between 10/2002 and 7/2010. Deferred lesion intervention was defined as any revascularization of a lesion previously deferred following FFR. The final DLI model was developed using stepwise Cox regression and validated using bootstrapping techniques. An algorithm was constructed to predict the 1-year risk of DLI. During a mean (±SD) follow-up period of 4.0 ± 2.3 years, 18% of lesions deferred after FFR underwent DLI; the 1-year incidence of DLI was 5.3%, while the predicted risk of DLI varied from 1 to 40%. The final Cox model included the FFR value, age, current or former smoking, history of coronary artery disease (CAD) or prior percutaneous coronary intervention, multi-vessel CAD, and serum creatinine. The c statistic for the DLI prediction model was 0.66 (95% confidence interval, CI: 0.61-0.70). Patients deferred revascularization based on FFR have variation in their risk for DLI. A clinical prediction model consisting of five clinical variables and the FFR value can help predict the risk of DLI in the first year following FFR assessment.

  15. Molecular interaction between K-Ras and H-REV107 in the Ras signaling pathway.

    Science.gov (United States)

    Han, Chang Woo; Jeong, Mi Suk; Jang, Se Bok

    2017-09-16

    Ras proteins are small GTPases that serve as master moderators of a large number of signaling pathways involved in various cellular processes. Activating mutations in Ras are found in about one-third of cancers. H-REV107, a K-Ras binding protein, plays an important role in determining K-Ras function. H-REV107 is a member of the HREV107 family of class II tumor suppressor genes and a growth inhibitory Ras target gene that suppresses cellular growth, differentiation, and apoptosis. Expression of H-REV107 was strongly reduced in about 50% of human carcinoma cell lines. However, the specific molecular mechanism by which H-REV107 inhibits Ras is still unknown. In the present study, we suggest that H-REV107 forms a strong complex with activating oncogenic mutation Q61H K-Ras from various biochemical binding assays and modeled structures. In addition, the interaction sites between K-Ras and H-REV107 were predicted based on homology modeling. Here, we found that some structure-based mutants of the K-Ras disrupted the complex formation with H-REV107. Finally, a novel molecular mechanism describing K-Ras and H-REV107 binding is suggested and insights into new K-Ras effector target drugs are provided. Copyright © 2017 Elsevier Inc.

  20. Rev Variation during Persistent Lentivirus Infection

    Directory of Open Access Journals (Sweden)

    Karin S. Dorman

    2011-01-01

    Full Text Available The ability of lentiviruses to continually evolve and escape immune control is the central impediment in developing an effective vaccine for HIV-1 and other lentiviruses. Equine infectious anemia virus (EIAV is considered a useful model for immune control of lentivirus infection. Virus-specific cytotoxic T lymphocytes (CTL and broadly neutralizing antibody effectively control EIAV replication during inapparent stages of disease, but after years of low-level replication, the virus is still able to produce evasion genotypes that lead to late re-emergence of disease. There is a high rate of genetic variation in the EIAV surface envelope glycoprotein (SU and in the region of the transmembrane protein (TM overlapped by the major exon of Rev. This review examines genetic and phenotypic variation in Rev during EIAV disease and a possible role for Rev in immune evasion and virus persistence.

  3. Structural model of the Rev regulatory protein from equine infectious anemia virus.

    Directory of Open Access Journals (Sweden)

    Yungok Ihm

    Full Text Available Rev is an essential regulatory protein in the equine infectious anemia virus (EIAV and other lentiviruses, including HIV-1. It binds incompletely spliced viral mRNAs and shuttles them from the nucleus to the cytoplasm, a critical prerequisite for the production of viral structural proteins and genomic RNA. Despite its important role in production of infectious virus, the development of antiviral therapies directed against Rev has been hampered by the lack of an experimentally-determined structure of the full length protein. We have used a combined computational and biochemical approach to generate and evaluate a structural model of the Rev protein. The modeled EIAV Rev (ERev structure includes a total of 6 helices, four of which form an anti-parallel four-helix bundle. The first helix contains the leucine-rich nuclear export signal (NES. An arginine-rich RNA binding motif, RRDRW, is located in a solvent-exposed loop region. An ERLE motif required for Rev activity is predicted to be buried in the core of modeled structure where it plays an essential role in stabilization of the Rev fold. This structural model is supported by existing genetic and functional data as well as by targeted mutagenesis of residues predicted to be essential for overall structural integrity. Our predicted structure should increase understanding of structure-function relationships in Rev and may provide a basis for the design of new therapies for lentiviral diseases.

  4. Why birds with deferred sexual maturity are sedentary on islands: a systematic review.

    Directory of Open Access Journals (Sweden)

    Miguel Ferrer

    Full Text Available BACKGROUND: Island faunas have played central roles in the development of evolutionary biology and ecology. Birds are among the most studied organisms on islands, in part because of their dispersal powers linked to migration. Even so, we lack of information about differences in the movement ecology of island versus mainland populations of birds. METHODOLOGY/PRINCIPAL FINDINGS: Here we present a new general pattern indicating that large birds with deferred sexual maturity are sedentary on islands, and that they become so even when they are migratory on the mainland. Density-dependent variation in the age at first breeding affects the survivorship of insular populations and this, in turn, affects the movement ecology of large birds. Because density-dependent variation in the age of first breeding is critical to the long-term survival of small isolated populations of long-lived species, migratory forms can successfully colonize islands only if they become sedentary once there. Analyses of the movement ecology of continental and insular populations of 314 species of raptors, 113 species of Ciconiiformes and 136 species of passerines, along with individual-based population simulations confirm this prediction. CONCLUSIONS: This finding has several consequences for speciation, colonization and survival of small isolated population of species with deferred sexual maturity.

    © 2015 Mathematical Sciences Publishers. Adaptive step-size control is a critical feature for the robust and efficient numerical solution of initial-value problems in ordinary differential equations. In this paper, we show that adaptive step-size control can be incorporated within a family of parallel time integrators known as revisionist integral deferred correction (RIDC) methods. The RIDC framework allows for various strategies to implement stepsize control, and we report results from exploring a few of them.

  11. Use of deferred consent for severely ill children in a multi-centre phase III trial

    Directory of Open Access Journals (Sweden)

    Boga Mwamvua

    2011-03-01

    Full Text Available Abstract Background Voluntary participation of a subject in research respects a subject's rights, strengthens its ethical conduct, and is formalized by the informed consent process. Clinical trials of life-saving interventions for medical emergencies often necessitate enrolment of patients where prior written individual informed consent is impossible. Although there are regulations and guidelines on protecting subjects in emergency research, these have been criticised for being limited and unnecessarily restrictive. Across Europe and the United States stringent regulations have resulted in a substantial decline of clinical trials involving emergency interventions. Methods We are conducting a trial of fluid resuscitation in children with hypovolaemic shock in six hospitals across three malaria-endemic African countries. The design is pragmatic as children are enrolled on clinical criteria alone and is being conducted in hospitals with facilities typical of many district hospitals across Africa. The trial aims to inform strategy for managing children with febrile illness and features of shock. In order to develop appropriate consent processes for the trial, we conducted a narrative review of current international recommendations for emergency consent. Results Practical or specific guidance was generally sparse or confusing with few examples in the literature to direct our informed consent process. For a sub-group of children who were critically sick or where parents themselves were otherwise too distressed to consider prior written consent, we opted for a modified form of deferred consent. This included verbal assent from guardians at the point of enrolment, with full written consent obtained after stabilising the child. For children who died prior to full written consent, ethical permission was received to waiver full consent. Conclusions In light of the controversy around guidance and regulations in this area we report how and why we have used a

    2014-07-18

    The HIV-1 protein Rev oligomerizes on viral transcripts and directs their nuclear export. Previously, a Fab against Rev generated by phage display was used to crystallize and solve the structure of the Rev oligomerization domain. Here we have investigated the capability of this Fab to block Rev oligomerization and inhibit HIV-1 replication. The Fab itself did not have antiviral activity, but when a Tat-derived cell-penetrating peptide was appended, the resulting molecule (FabRev1-Tat) was strongly inhibitory of three different CCR5-tropic HIV-1 isolates (IC50 = 0.09-0.44 μg/ml), as assessed by suppression of reverse transcriptase activity in infected peripheral blood mononuclear cells, and had low cell toxicity (TC50 > 100 μg/ml). FabRev1-Tat was taken up by both peripheral blood mononuclear and HEK293T cells, appearing in both the cytoplasm and nucleus, as shown by immunofluorescence confocal laser scanning microscopy. Computational alanine scanning was used to identify key residues in the complementarity-determining regions to guide mutagenesis experiments. Residues in the light chain CDR3 (LCDR3) were assessed to be important. Residues in LCDR3 were mutated, and LCDR3-Tyr(92) was found to be critical for binding to Rev, as judged by surface plasmon resonance and electron microscopy. Peptides corresponding to all six CDR regions were synthesized and tested for Rev binding. None of the linear peptides had significant affinity for Rev, but four of the amide-cyclic forms did. Especially cyclic-LCDR3 (LGGYPAASYRTA) had high affinity for Rev and was able to effectively depolymerize Rev filaments, as shown by both surface plasmon resonance and electron microscopy.

  3. Performance of Lempel-Ziv compressors with deferred innovation

    Science.gov (United States)

    Cohn, Martin

    1989-01-01

    The noiseless data-compression algorithms introduced by Lempel and Ziv (LZ) parse an input data string into successive substrings each consisting of two parts: The citation, which is the longest prefix that has appeared earlier in the input, and the innovation, which is the symbol immediately following the citation. In extremal versions of the LZ algorithm the citation may have begun anywhere in the input; in incremental versions it must have begun at a previous parse position. Originally the citation and the innovation were encoded, either individually or jointly, into an output word to be transmitted or stored. Subsequently, it was speculated that the cost of this encoding may be excessively high because the innovation contributes roughly 1g(A) bits, where A is the size of the input alphabet, regardless of the compressibility of the source. To remedy this excess, it was suggested to store the parsed substring as usual, but encoding for output only the citation, leaving the innovation to be encoded as the first symbol of the next substring. Being thus included in the next substring, the innovation can participate in whatever compression that substring enjoys. This strategy is called deferred innovation. It is exemplified in the algorithm described by Welch and implemented in the C program compress that has widely displaced adaptive Huffman coding (compact) as a UNIX system utility. The excessive expansion is explained, an implicit warning is given against using the deferred innovation compressors on nearly incompressible data.

    The nuclear receptors for heme, REV-ERBα and REV-ERBβ, play important roles in the regulation of metabolism and inflammation. Recently it was demonstrated that reduced REV-ERBα expression in hematopoetic cells in LDL receptor null mice led to increased atherosclerosis. We sought to determine if synthetic REV-ERB agonists that we have developed might have the ability to suppress atherosclerosis in this model. A previously characterized synthetic REV-ERB agonist, SR9009, was used to determine if activation of REV-ERB activity would affect atherosclerosis in LDL receptor deficient mice. Atherosclerotic plaque size was significantly reduced (p < 0.05) in mice administered SR9009 (100 mg/kg) for seven weeks compared to control mice (n = 10 per group). SR9009 treatment of bone marrow-derived mouse macrophages (BMDM) reduced the polarization of BMDMs to proinflammatory M1 macrophage while increasing the polarization of BMDMs to anti-inflammatory M2 macrophages. Our results suggest that pharmacological targeting of REV-ERBs may be a viable therapeutic option for treatment of atherosclerosis. - Highlights: • Synthetic REV-ERB agonist treatment reduced atherosclerosis in a mouse model. • Pharmacological activation of REV-ERB decreased M1 macrophage polarization. • Pharmacological activation of REV-ERB increased M2 macrophage polarization.

    Each year, a large number of individuals in Australia are deferred from donating blood. A deferral may have a negative impact on donor satisfaction and subsequent word-of-mouth communication. The Australian Red Cross Blood Service (the Blood Service) is, therefore, investigating options for managing service interactions with deferred donors to maintain positive relationships. While public research institutes in Australia have established independent research donor registries, other countries provide programmes allowing deferred donors to donate blood for research via blood collection agencies. This study examined attitudes towards donating blood for research use in a sample of permanently deferred Australian donors. Donors permanently deferred because of a risk of variant Creutzfeldt-Jakob disease (n=449) completed a postal survey that examined attitudes towards research donation. The majority of participants were interested in donating blood for research (96%), and joining a registry of research donors (93%). Participants preferred to donate for transfusion or clinical research, and were willing to travel large distances. Results indicated that positive attitudes towards the Blood Service would be extended if the opportunity to donate blood was provided. These findings indicate a desire for continued engagement with the Blood Service despite deferral. Donating blood for research is a potential way of maintaining positive relationships with permanently deferred donors which also benefits the health research community. Through maintaining positive relationships with deferred donors, positive word-of-mouth activity can be stimulated. Further work is needed to determine the feasibility of implementing research donation through the Blood Service in Australia.

    The objective for the analysis has been to establish data for the sea at Horns Rev wind farm in the North Sea in order to assess the opportunity for using the site as test site for demonstration of wave energy devices exemplified by three different devices under development in Denmark. For comparison alternative sites like Hanstholm, Samsoe and Nissum Bredning are also assessed as well as the test centre EMEC at the Orkney Islands and the proposed test site Wave Hub at the north coast of Cornwall. The analysis shows that it is possible without major technical problems to connect 2-4 MW power generated by 3 different wave energy devices (AquaBuOY, Wave Star Energy and Wave Dragon) to the wind farm at Horns Rev (www.hornsrev.dk). The expenses for connection and regulation within the wind farm is about 200,000 DKK (30,00 EURO). On top of this comes the cost for individual sub sea cable connection to the wave devices, pull in of the sub sea cable through the existing J-tube in turbine T04 and the necessary regulation/control system in the individual wave devices to avoid damaging the power system in case of too high production. The analysis of the co-production of wind and wave power is dealt with in a separate report which shows that over a time period of half to one hour the time variation for wind generated electricity is 3 times as large as for wave energy generated power based on the actual measurement at Horns Rev. Further on the analysis shows that the wave generated power is more predictable than wind energy generated power as the power from the waves first is present about 2 hours after the wind is acting and last for 3 to 6 hours after the wind dies out; 6 to 12 hours with wind from west. The time is off course strongly depending of the direction of the wind i.e. the fetch. As this special report has a more general scope than the analysis as such it is reported in English (Annex Report II). The analysis shows that it is up to the individual device developer

  16. DNA nuclease activity of Rev-coupled transition metal chelates.

    2012-06-07

    Artificial nucleases containing Rev-coupled metal chelates based on combinations of the transition metals Fe(2+), Co(2+), Ni(2+), and Cu(2+) and the chelators DOTA, DTPA, EDTA, NTA, tripeptide GGH, and tetrapeptide KGHK have been tested for DNA nuclease activity. Originally designed to target reactive transition metal chelates (M-chelates) to the HIV-1 Rev response element mRNA, attachment to the arginine-rich Rev peptide also increases DNA-binding affinity for the attached M-chelates. Apparent K(D) values ranging from 1.7 to 3.6 µM base pairs for binding of supercoiled pUC19 plasmid DNA by Ni-chelate-Rev complexes were observed, as a result of electrostatic attraction between the positively-charged Rev peptide and negatively-charged DNA. Attachment of M-chelates to the Rev peptide resulted in enhancements of DNA nuclease activity ranging from 1-fold (no enhancement) to at least 13-fold (for Cu-DTPA-Rev), for the rate of DNA nicking, with second order rate constants for conversion of DNA(supercoiled) to DNA(nicked) up to 6 × 10(6) M(-1) min(-1), and for conversion of DNA(nicked) to DNA(linear) up to 1 × 10(5) M(-1) min(-1). Freifelder-Trumbo analysis and the ratios of linearization and nicking rate constants (k(lin)/k(nick)) revealed concerted mechanisms for nicking and subsequent linearization of plasmid DNA for all of the Rev-coupled M-chelates, consistent with higher DNA residency times for the Rev-coupled M-chelates. Observed rates for Rev-coupled M-chelates were less skewed by differing DNA-binding affinities than for M-chelates lacking Rev, as a result of the narrow range of DNA-binding affinities observed, and therefore relationships between DNA nuclease activity and other catalyst properties, such as coordination unsaturation, the ability to consume ascorbic acid and generate diffusible radicals, and the identity of the metal center, are now clearly illustrated in light of the similar DNA-binding affinities of all M-chelate-Rev complexes.

  17. Requirement of DDX3 DEAD box RNA helicase for HIV-1 Rev-RRE export function.

    A single transcript in its unspliced and spliced forms directs the synthesis of all HIV-1 proteins. Although nuclear export of intron-containing cellular transcripts is restricted in mammalian cells, HIV-1 has evolved the viral Rev protein to overcome this restriction for viral transcripts. Previously, CRM1 was identified as a cellular cofactor for Rev-dependent export of intron-containing HIV-1 RNA. Here, we present evidence that Rev/CRM1 activity utilizes the ATP-dependent DEAD box RNA helicase, DDX3. We show that DDX3 is a nucleo-cytoplasmic shuttling protein, which binds CRM1 and localizes to nuclear membrane pores. Knockdown of DDX3 using either antisense vector or dominant-negative mutants suppressed Rev-RRE-function in the export of incompletely spliced HIV-1 RNAs. Plausibly, DDX3 is the human RNA helicase which functions in the CRM1 RNA export pathway analogously to the postulated role for Dbp5p in yeast mRNA export.

  18. ‘Humblewise’: Deference and Complaint in the Court of Requests

    Directory of Open Access Journals (Sweden)

    Liam J. Meyer

    2015-03-01

    Full Text Available When servants, laborers, and apprentices sued their masters for back wages or mistreatment in the Court of Requests they took advantage of the court’s doctrine of equity. Since these plaintiffs often lacked the strict written proofs required by common law, or were bound by unfair written contracts, they badly needed an equitable jurisdiction where fairness, extenuating circumstances, and broad social mores could overrule the letter of the law. The formal tropes of their Complaints negotiate the tension between these two conceptions of justice and reveal how that tension relates to early seventeenth century economic culture, where customary ideas about patronage and hierarchical obligations coexisted with emerging notions of self-interest and contractual equality. In appealing to the court with older but still vibrant discourses of social justice and mutual obligation, plaintiffs modulated their Complaints with expressions of deference and helplessness. Their pleadings therefore take the sophisticated rhetorical form of self-assertion articulated as abject submission. The documents are highly mediated by lawyers and institutional constraints, but nevertheless reveal subordinates tactically using expressions of weakness to elicit pathos and use the ideology of paternalism against their masters.

  20. Peptides derived from HIV-1 integrase that bind Rev stimulate viral genome integration.

    Directory of Open Access Journals (Sweden)

    Aviad Levin

    Full Text Available BACKGROUND: The human immunodeficiency virus type 1 (HIV-1 integrase protein (IN, catalyzes the integration of viral DNA into the host cell genome. IN catalyzes the first step of the integration process, namely the 3'-end processing in which IN removes a pGT dinucleotide from the 3' end of each viral long terminal repeat (LTR. Following nuclear import of the viral preintegration complex, the host chromosomal DNA becomes accessible to the viral cDNA and the second step of the integration process, namely the strand-transfer step takes place. This ordered sequence of events, centered on integration, is mandatory for HIV replication. METHODOLOGY/PRINCIPAL FINDINGS: Using an integrase peptide library, we selected two peptides, designated INr-1 and INr-2, which interact with the Rev protein and probably mediate the Rev-integrase interaction. Using an in-vitro assay system, we show that INr-1 and INr-2 are able to abrogate the inhibitory effects exerted by Rev and Rev-derived peptides on integrase activity. Both INr-1 and INr-2 were found to be cell-permeable and nontoxic, allowing a study of their effect in HIV-1-infected cultured cells. Interestingly, both INr peptides stimulated virus infectivity as estimated by production of the viral P24 protein, as well as by determination of the appearance of newly formed virus particles. Furthermore, kinetics studies revealed that the cell-permeable INr peptides enhance the integration process, as was indeed confirmed by direct determination of viral DNA integration by real-time PCR. CONCLUSIONS/SIGNIFICANCE: The results of the present study raise the possibility that in HIV-infected cells, the Rev protein may be involved in the integration of proviral DNA by controlling/regulating the activity of the integrase. Release from such inhibition leads to stimulation of IN activity and multiple viral DNA integration events.

    Full Text Available Heme is a ligand for the human nuclear receptors (NR REV-ERBalpha and REV-ERBbeta, which are transcriptional repressors that play important roles in circadian rhythm, lipid and glucose metabolism, and diseases such as diabetes, atherosclerosis, inflammation, and cancer. Here we show that transcription repression mediated by heme-bound REV-ERBs is reversed by the addition of nitric oxide (NO, and that the heme and NO effects are mediated by the C-terminal ligand-binding domain (LBD. A 1.9 A crystal structure of the REV-ERBbeta LBD, in complex with the oxidized Fe(III form of heme, shows that heme binds in a prototypical NR ligand-binding pocket, where the heme iron is coordinately bound by histidine 568 and cysteine 384. Under reducing conditions, spectroscopic studies of the heme-REV-ERBbeta complex reveal that the Fe(II form of the LBD transitions between penta-coordinated and hexa-coordinated structural states, neither of which possess the Cys384 bond observed in the oxidized state. In addition, the Fe(II LBD is also able to bind either NO or CO, revealing a total of at least six structural states of the protein. The binding of known co-repressors is shown to be highly dependent upon these various liganded states. REV-ERBs are thus highly dynamic receptors that are responsive not only to heme, but also to redox and gas. Taken together, these findings suggest new mechanisms for the systemic coordination of molecular clocks and metabolism. They also raise the possibility for gas-based therapies for the many disorders associated with REV-ERB biological functions.

    Nucleic acid amplification tests (NAATs) are recommended for the diagnosis of N. gonorrhoeae infections because of their superior sensitivity. Increasing NAAT use causes a decline in crucial antimicrobial resistance (AMR) surveillance data, which rely on culture. We analyzed the suitability of the ESwab system for NAAT diagnostics and deferred targeted N. gonorrhoeae culture to allow selective and efficient culture based on NAAT results. We included patients visiting the STI Clinic Amsterdam, The Netherlands, in 2013. Patient characteristics and urogenital and rectal samples for direct N. gonorrhoeae culture, standard NAAT, and ESwab were collected. Standard NAAT and NAAT on ESwab samples were performed using the Aptima Combo 2 assay for N. gonorrhoeae and C. trachomatis. Two deferred N. gonorrhoeae cultures were performed on NAAT-positive ESwab samples after storage at 4°C for 1 to 3 days. We included 2,452 samples from 1,893 patients. In the standard NAAT, 107 samples were N. gonorrhoeae positive and 284 were C. trachomatis positive. The sensitivities of NAAT on ESwab samples were 83% (95% confidence interval [CI], 75 to 90%) and 87% (95% CI, 82 to 90%), respectively. ESwab samples were available for 98 of the gonorrhea-positive samples. Of these, 82% were positive in direct culture and 69% and 56% were positive in the 1st and 2nd deferred cultures, respectively (median storage times, 27 and 48 h, respectively). Deferred culture was more often successful in urogenital samples or when the patient had symptoms at the sampling site. Deferred N. gonorrhoeae culture of stored ESwab samples is feasible and enables AMR surveillance. To limit the loss in NAAT sensitivity, we recommend obtaining separate samples for NAAT and deferred culture.

    Current evidence supports deferral of revascularization for lesions with fractional flow reserve (FFR) values >0.80. The natural history after deferral of revascularization of lesions with borderline FFR values is unknown. This study evaluated the outcomes of patients after deferred revascularization of coronary stenoses based on a borderline FFR value. We retrospectively studied 720 patients with 881 intermediate-severity coronary stenoses who underwent FFR assessment from October 2002 to July 2010 and were deferred revascularization. Patients were divided into gray zone (0.75 to 0.80), borderline (0.81 to 0.85), and nonborderline (>0.85) FFR groups. Any subsequent percutaneous coronary intervention or coronary artery bypass grafting of a deferred stenosis during follow-up was classified as a deferred lesion intervention (DLI). Patient and/or lesion characteristics and clinical outcomes were compared between the FFR groups using univariate and propensity score-adjusted inverse probability of weighting Cox proportional hazards analyses. During a mean follow-up of 4.5 ± 2.1 years, 157 deferred lesions (18%) underwent DLI by percutaneous coronary intervention (n = 117) or coronary artery bypass grafting (n = 40). No statistically significant differences were observed in clinical outcomes between the gray zone and borderline FFR groups. Lesions with a borderline FFR were associated with a significantly higher risk of DLI compared with lesions with nonborderline FFR values (hazard ratio 1.63, 95% confidence interval 1.14 to 2.33, p = 0.007). Lesions deferred revascularization because of a borderline FFR (0.81 to 0.85) were associated with a higher risk of DLI compared with lesions with a nonborderline FFR (>0.85). Further study is needed to determine the optimal management of coronary stenoses with a borderline FFR value. Copyright © 2014 Elsevier Inc. All rights reserved.

  9. A Circular Motion Activity with Hot Wheels® Rev-Ups

    2009-02-01

    Hot Wheels® Rev-Ups provide a pedagogically engaging and inexpensive culminating activity for the application of circular motion with constant speed in introductory mechanics. The introductory Rev-Up, shown in Fig. 1, consists of a very durable car with two strong magnets built into the front and back of the car. The track is a piece of flexible plastic with a built-in metallic strip through its center that can then be formed into a circle. Pushing the car forward several times on a flat surface allows the car to move in a vertical circle when placed inside the track. What makes this toy attractive is that the gearing system allows the car to move at a relatively constant speed for about three to five seconds before slowing down appreciably.

    Both HIV infection and antiretroviral therapy (ART) are associated with lower bone mineral density (BMD) and increased fracture risk. Because the relative contributions of ART and untreated HIV to BMD loss are unclear, it is important to quantify the effect of ART on bone.

    Full Text Available This study evaluated the effect of four types of supplement on the finishing of Nellore cattle on deferred Brachiaria decumbens pasture during the dry season. Sixty-four castrated Nellore males with an age of approximately 34 months and initial body weight (BW ranging from 360 to 380 kg were divided into 16 animals per treatment in a completely randomized design. The treatments consisted of four types of pasture supplement: deferred Brachiaria decumbens pasture + energy protein mineral salt (SuEPM used as control; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + ground corn grain (SuCo; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + citrus pulp (SuCPu; deferred Brachiaria decumbens pasture + urea + cottonseed meal (28% CP + soy hull (SuSH. The pasture was deferred for 170 days and provided 3,482 kg DM/ha of forage, permitting a stocking rate of 1.56 AU/ha (DM intake of 2.25% BW and 50% pasture efficiency. The animals received the supplement ad libitum in the SuEPM treatment and as % BW in the other treatments from July to October. The animals were slaughtered at a minimum BW of 457 kg. The following variables were evaluated: final weight, weight gain during the period (WG, average daily gain (ADG, hot carcass weight (HCW, and hot carcass yield (HCY. With respect to final weight, the supplement in the SuCo, SuCPu and SuSH treatments permitted a greater supply of nutrients and the animals therefore exhibited better performance (P<0.05 compared to the SuEPM treatment (mean of 478.68 vs 412.62 kg. The same effect was observed for the other parameters studied. Analysis of WG and ADG showed that SuSH was superior to the SuCo and SuCPu treatments (P<0.05 due to the increased offer of concentrate and SuEPM was inferior to the other treatments. Higher HCW (260.05 kg and HCY (53.92% were obtained with treatment SuSH as a result of greater performance. Supplementation of cattle during the dry period on

    We study the impact of the different tax treatment of capital gains and losses on the optimal location of assets in taxable and tax-deferred accounts. The classical result of Black (1980) and Tepper (1981) suggests that investors should follow a strict pecking order asset location rule and hold...... those assets that are subject to the highest tax rate preferentially in tax-deferred accounts. We show that with the different tax treatment of realized gains and losses, only tax-efficient equity mutual funds are optimally held in taxable accounts, whereas mutual funds with average tax...

    Full Text Available Introduction: Disruption in bone homeostasis with increased osteoclastic resorption may lead to osteoporosis. HIV tat has been found to increase differentiation of precursor cells into osteoclast (OC (1. Presence of soluble HIV proteins in virally suppressed HIV patients on ART may drive a bone resorption phenotype. We investigated the role of soluble HIV proteins (tat, gp120 Mn and Bal, rev and p55-gag on osteoclastogenesis and OC resorptive capacity. Methods: Mouse monocyte RAW 264.7 cells were cultured in vitro and induced to differentiate into OCs with 50 ng/mL RANKL and 25 ng/mL mCSF. Medium was supplemented with 100 ng/mL of recombinant HIV tat, gp120 (Mn and Bal, rev, nef and p55-gag, respectively, with zolendronate as negative control. Differentiated OCs were stained for TRAP and counted. OC resorption function was examined by culturing differentiated OCs (in the presence of respective HIV proteins on dentin-coated plates and examining the following (i sealing zone formation, (ii volume of resorption pits and (iii area of resorption pits per field using confocal microscopy. Expression of OC specific genes including NFATc1 and cathepsin K was investigated by qPCR. Reactive oxygen species (ROS production is essential in RANKL-induced OC differentiation (2,3; effect of these proteins on ROS production was assessed using the fluorescent H2DCFH-DA. Mean fluorescence intensity was then measured by flow cytometry. TNFα production by OC precursors when incubated with tat and rev was measured by ELISA. Results: Tat and rev treatment was associated with increased OC formation by 70 and 26%, respectively (p<0.01, relative to control, while zolendronate significantly inhibited OC formation by 75%. Gp120 Mn and Bal, nef and p55-gag treatment had no effect on OC differentiation. Interestingly, neither tat nor rev treatment caused significant increases in sealing zone formation but increased dentin resorption pit area by 28 and 19%, respectively, and

  17. Intermolecular masking of the HIV-1 Rev NLS by the cellular protein HIC: novel insights into the regulation of Rev nuclear import.

    LENUS (Irish Health Repository)

    Gu, Lili

    2011-01-01

    The HIV-1 regulatory protein Rev, which is essential for viral replication, mediates the nuclear export of unspliced viral transcripts. Rev nuclear function requires active nucleocytoplasmic shuttling, and Rev nuclear import is mediated by the recognition of its Nuclear Localisation Signal (NLS) by multiple import factors, which include transportin and importin β. However, it remains unclear which nuclear import pathway(s) predominate in vivo, and the cellular environment that modulates Rev nucleocytoplasmic shuttling remains to be characterised.

  10. The impact of excess choice on deferment of decisions to volunteer

    Directory of Open Access Journals (Sweden)

    Lauren S. Carroll

    2011-10-01

    Full Text Available Excess choice has previously been shown to have detrimental effects on decisions about consumer products. As the number of options increases, people are more likely to put off making an active choice (i.e., defer and show less satisfaction with any purchase actually made. We extend this line of enquiry to choosing a charitable organisation to volunteer for. The issue is important because the number of voluntary organisations is enormous and the impact of such a decision may be greater than for consumer decisions in terms of time commitment and benefits to the volunteer and society. Study 1 asked students to examine a real volunteering website and record how many organisations they considered, decision difficulty and whether or not they would like to sign up for a chosen organisation or prefer to defer a decision. Study 2 presented either a relatively small (10 or large (30 choice set of hypothetical organisations and measured deferment likelihood and decision difficulty. In both studies the more options considered, the greater the likelihood to defer. This effect was mediated by decision difficulty. This research is the first to find that detrimental effects of excess choice extend to volunteering. Implications for volunteer recruitment are discussed.

    Full Text Available Abstract Objective To evaluate the feasibility of a large immediate versus deferred antiretroviral therapy (ART study in children. Methods We conducted an open-label pilot randomized clinical trial study in 43 Thai children with CD4 15 to 24% of starting generic AZT/3TC/NVP immediately (Arm 1 or deferring until CD4 Results Recruitment took 15 months. Twenty-six of 69 (37.7% were not eligible due mainly to low CD4%. Twenty four and 19 were randomized to arms 1 and 2 respectively. All accepted the randomized arm; however, 3 in arm 1 stopped ART and 1 in arm 2 refused to start ART. Ten/19 (53% in arm 2 started ART. At baseline, median age was 4.8 yrs, CDC A:B were 36:7, median CD4 was 19% and viral load was 4.8 log. All in arm 1 and 17/19 in arm 2 completed the study (median of 134 weeks. No one had AIDS or death. Four in immediate arm had tuberculosis. Once started on ART, deferred arm children achieved similar CD4 and viral load response as the immediate arm. Adverse events were similar between arms. The deferred arm had a 26% ART saving. Conclusion Almost 40% of children were not eligible due mainly to low CD4% but adherence to randomized treatment and retention in trial were excellent. A larger study to evaluate when to start ART is feasible.

  18. Overlapping cis sites used for splicing of HIV-1 env/nef and rev mRNAs.

    Science.gov (United States)

    Swanson, A K; Stoltzfus, C M

    1998-12-18

    Alternative splicing is used to generate more than 30 human immunodeficiency virus type 1 (HIV-1) spliced and unspliced mRNAs from a single primary transcript. The abundance of HIV-1 mRNAs is determined by the efficiencies with which its different 5' and 3' splice sites are used. Three splice sites (A4c, A4a, and A4b) are upstream of the rev initiator AUG. RNAs spliced at A4c, A4a, and A4b are used as mRNAs for Rev. Another 3' splice site (A5) is immediately downstream of the rev initiator. RNAs spliced at A5 are used as mRNAs for Env and Nef. In this report, primer extension analysis of splicing intermediates was used to show that there are eight branch points in this region, all of which map to adenosine residues. In addition, cis elements recognized by the cellular splicing machinery overlap; the two most 3' branch points overlap with the AG dinucleotides at rev 3' splice sites A4a and A4b. Competition of the overlapping cis sites for different splicing factors may play a role in maintaining the appropriate balance of mRNAs in HIV-1-infected cells. In support of this possibility, mutations at rev 3' splice site A4b AG dinucleotide dramatically increased splicing of the env/nef 3' splice site A5. This correlated with increased usage of the four most 3' branch points, which include those within the rev 3' splice site AG dinucleotides. Consistent with these results, analysis of a mutant in which three of the four env/nef branch points were inactivated indicated that use of splice site A5 was inhibited and splicing was shifted predominantly to the most 5' rev 3' splice site A4c with preferential use of the two most 5' branch points. Our results suggest that spliceosomes formed at rev A4a-4b, rev A4c, and env/nef A5 3' splice sites each recognize different subsets of the eight branch point sequences.

    Abstract Background The HIV-1 regulatory protein Rev, which is essential for viral replication, mediates the nuclear export of unspliced viral transcripts. Rev nuclear function requires active nucleocytoplasmic shuttling, and Rev nuclear import is mediated by the recognition of its Nuclear Localisation Signal (NLS) by multiple import factors, which include transportin and importin β. However, it remains unclear which nuclear import pathway(s) predominate in vivo, and the cellular environment that modulates Rev nucleocytoplasmic shuttling remains to be characterised. Results In our study, we have identified the cellular protein HIC (Human I-mfa domain-Containing protein) as a novel interactor of HIV-1 Rev. We demonstrate that HIC selectively interferes with Rev NLS interaction with importin β and impedes its nuclear import and function, but does not affect Rev nuclear import mediated by transportin. Hence, the molecular determinants mediating Rev-NLS recognition by importin β and transportin appear to be distinct. Furthermore, we have employed HIC and M9 M, a peptide specifically designed to inhibit the transportin-mediated nuclear import pathway, to characterise Rev nuclear import pathways within different cellular environments. Remarkably, we could show that in 293T, HeLa, COS7, Jurkat, U937, THP-1 and CEM cells, Rev nuclear import is cell type specific and alternatively mediated by transportin or importin β, in a mutually exclusive fashion. Conclusions Rev cytoplasmic sequestration by HIC may represent a novel mechanism for the control of Rev function. These studies highlight that the multivalent nature of the Rev NLS for different import receptors enables Rev to adapt its nuclear trafficking strategy.

    Science.gov (United States)

    Welch, Ryan D.; Flaveny, Colin A.

    2017-08-01

    Muscle is primarily known for its mechanical roles in locomotion, maintenance of posture, and regulation of cardiac and respiratory function. There are numerous medical conditions that adversely affect muscle, myopathies that disrupt muscle development, regeneration and protein turnover to detrimental effect. Skeletal muscle is also a vital secretory organ that regulates thermogenesis, inflammatory signaling and directs context specific global metabolic changes in energy substrate preference on a daily basis. Myopathies differ in the causative factors that drive them but share common features including severe reduction in quality of life and significantly increased mortality all due irrefutably to the loss of muscle mass. Thus far clinically viable approaches for preserving muscle proteins and stimulating new muscle growth without unwanted side effects or limited efficacy has been elusive. Over the last few decades, evidence has emerged through in vitro and in vivo studies that suggest the nuclear receptors REV-ERB and ROR might modulate pathways involved in myogenesis and mitochondrial biogenesis. Hinting that REV-ERB and ROR might be targeted to treat myopathies. However there is still a need for substantial investigation into the roles of these nuclear receptors in in vivo rodent models of degenerative muscle diseases and acute injury. Although exciting, REV-ERB and ROR have somewhat confounding roles in muscle physiology and therefore more studies utilizing in vivo models of skeletal muscle myopathies are needed. In this review we highlight the molecular forces driving some of the major degenerative muscular diseases and showcase two promising molecular targets that may have the potential to treat myopathies: ROR and REV-ERB.

    2015-01-01

    Given the increasing use of stock options in executive compensation, we examine how taxes influence the choice of compensation and document that income deferral is an important margin of adjustment in response to tax rate changes. To account for this option in the empirical analysis, we explore deferral by estimating how executives’ choice of compensation between current and deferred income depends on changes in tax policy. Our empirical results suggest a significant impact of taxes on the co...

    We explore the impact of authorization on the poverty exposure of households headed by undocumented immigrants. The identification strategy makes use of the 2012 Deferred Action for Childhood Arrivals (DACA) program, which provided a temporary work authorization and reprieve from deportation to eligible immigrants. Using a difference-in-differences approach, we compare DACA-eligible to DACA-ineligible likely unauthorized immigrants, before and after the program implementation. We find that DA...

    Human immunodeficiency virus type 1 (HIV-1) exploits multiple host factors during its replication. The REV/RRE-dependent nuclear export of unspliced/partially spliced viral transcripts needs the assistance of host proteins. Recent studies have shown that MOV10 overexpression inhibited HIV-1 replication at various steps. However, the endogenous MOV10 was required in certain step(s) of HIV-1 replication. In this report, we found that MOV10 potently enhances the nuclear export of viral mRNAs and subsequently increases the expression of Gag protein and other late products through affecting the Rev/RRE axis. The co-immunoprecipitation analysis indicated that MOV10 interacts with Rev in an RNA-independent manner. The DEAG-box of MOV10 was required for the enhancement of Rev/RRE-dependent nuclear export and the DEAG-box mutant showed a dominant-negative activity. Our data propose that HIV-1 utilizes the anti-viral factor MOV10 to function as a co-factor of Rev and demonstrate the complicated effects of MOV10 on HIV-1 life cycle. - Highlights: • MOV10 can function as a co-factor of HIV-1 Rev. • MOV10 facilitates Rev/RRE-dependent transport of viral mRNAs. • MOV10 interacts with Rev in an RNA-independent manner. • The DEAG-box of MOV10 is required for the enhancement of Rev/RRE-dependent export.

  15. Horns Rev offshore wind farm. Environmental impact assessment of sea bottom and marine biology

    2000-03-15

    An Environmental Impact Assessment (EIA) of a planned 150 MW offshore wind farm at Horns Rev has been carried out for the marine biology and sea bottom in the area, and includes vegetation and benthic fauna. The study forms part of a total EIA of the planned offshore wind farm. This EIA study has been drawn up in accordance with the guidelines laid down by the Ministry of Environment and Energy in the publication, 'Guidelines for preparation of EIAstudies for offshore wind farms. Horns Rev is situated off Blaevands Huk, which is Denmark's most westerly point. It is a shallow reef with water depths between 2 and 9 metres and is primarily composed of sand, gravel and pebbles. The area designated for the wind farm lies directly south of Horns Rev and is dominated by sand with a median particle size of 0.3 mm. Along the edges, towards areas of greater depth, the particle size increases. There are areas of fine sand in the deepest area, and in isolated pockets within the proposed wind farm site. The sediment is characterised by a very low (<1%) organic matter content. On the basis of the expected impact from the establishment of the wind farm, it is not deemed necessary to carry out special programmes during the construction phase for monitoring of the environmental-biological conditions. A monitoring and control programme is recommended during the production phase in order to follow the copper concentration in bivalves, or alternatively to initiate recovery or elimination of the copper-laden waste. A control programme is recommended during the production phase in order to follow the establishment and succession of the fouling community on the wind turbine foundations and scour-protecting revetments.

    The 12MW project with the full title '12 MW wind turbines: the scientific basis for their operation at 70 to 270 m height offshore' has the goal to experimentally investigate the wind and turbulence characteristics between 70 and 270 m above sea level and thereby establish the scientific basis relevant for the next generation of huge 12 MW wind turbines operating offshore. The report describes the experimental campaign at the Horns Rev offshore wind farm at which observations from Doppler Laser LIDAR and SODAR were collected from 3 May to 24 October 2006. The challenges for mounting and operating the instruments on the transformer platform at Horns Rev were overcome by a close collaboration between DONG energy and Risoe National Laboratory DTU. The site is presented. In particular, three tall offshore meteorological masts, up to 70 m tall, provided a useful source of meteorological data for comparison to the remotely sensed wind and turbulence observations. The comparison showed high correlation. The LIDAR and SODAR wind and turbulence observations were collected far beyond the height of the masts (up to 160 m above sea level) and the extended profiles were compared to the logarithmic wind profile. Further studies on this part of the work are on-going. Technical detail on LIDAR and SODAR are provided as well as theoretical work on turbulence and atmospheric boundary layer flow. Selected results from the experimental campaign are reported. (au)

    The Rev proteins of the related but distinct human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2) display incomplete functional reciprocity. One possible explanation for this observation is that HIV-2 Rev is unable to interact with the HIV-1 Rev-response element (RRE1). However, an analysis of the biological activity of chimeric proteins derived from HIV-1 and HIV-2 Rev reveals that this target specificity does not map to the Rev RNA binding domain but is instead primarily determined ...

    2012-09-01

    To fulfill Food and Drug Administration and Department of Health and Human Services emergency care research informed consent requirements, our burn center planned and executed a deferred consent strategy gaining Institutional Review Board (IRB) approval to proceed with the clinical study. These federal regulations dictate public disclosure and community consultation unique to acute care research. Our regional burn center developed and implemented a deferred consent public notification and community consultation paradigm appropriate for a burn study. Published accounts of deferred consent strategies focus on acute care resuscitation practices. We adapted those strategies to design and conduct a comprehensive public notification/community consultation plan to satisfy deferred consent requirements for burn center research. To implement a robust media campaign we engaged the hospital's public relations department, distributed media materials, recruited hospital staff for speaking engagements, enlisted community volunteers, and developed initiatives to inform "hard-to-reach" populations. The hospital's IRB determined we fulfilled our obligation to notify the defined community. Our communication strategy should provide a paradigm other burn centers may appropriate and adapt when planning and executing a deferred consent initiative. Copyright © 2012 Elsevier Ltd and ISBI.

    Full Text Available The objective of this study was to evaluate the effect of different levels of nitrogen on deferred pastures of Urochloa brizantha cv. Marandu, and the implications on the economic viability of production of Nellore heifers. This was a completely randomized design with four treatments (T1 = deferred pasture without nitrogen fertilization; T2 = deferred pasture fertilized with 50 kg N ha-1, T3 = deferred pasture with 100 kg N ha-1, T4 = deferred pasture with 150 kg N ha-1 and four replications (16 fertilized paddocks. First, there were used 48 Nellore heifers, average eight months of age and initial body weight of 178.69 ± 26.67 kg, with three heifers in each paddock, in all treatments, in a continuous grazing system, with variable stocking rate. Only the treatment the without nitrogen fertilization showed negative monetary values of R$ -181.96, R$ ha-1 -72.79 and R$ @-1 -32.11. The treatment with 50 kg N ha-1 achieved the highest positive monetary values of R$ 756.02, R$ ha-1 302.40 and R$ @-1 50.52. Economic viability data in beef heifer production demonstrate that the treatment with 50 kg N ha-1 is the most financially viable under the conditions of this study.

    In 2006, Dong Energy initiated the development of the Horns Rev II offshore wind farm in the North Sea. In order to evaluate and map the characteristics of the surface features of the sea bed and to characterise the subsurface in the wind farm area, the Geological Survey of Denmark and Greenland (GEUS) conducted a geophysical survey of the area. The survey utilised a variety of instruments: sparker, side-scan sonar, marine caesium magnetometer and a multibeam echo-sounder. In addition, information on the subsurface sediments was obtained by cone penetration tests (CPT) and by drilling to 30-50 m below the sea bottom. Geological correlation of the CPT results with the other survey results was extremely complicated but was required in order to understand the architecture of the ice marginal glaciotectonic complex. Information on the geology is crucial for evaluation of the geotechnical problems of the region. (au)

  3. Great apes can defer exchange: a replication with different results suggesting future oriented behavior.

    2013-01-01

    The topic of cognitive foresight in non-human animals has received considerable attention in the last decade. The main questions concern whether the animals can prepare for upcoming situations which are, to various degrees, contextually or sensorially detached from the situation in which the preparations are made. Studies on great apes have focused on tool-related tasks, e.g., the ability to select a tool which is functional only in the future. Dufour and Sterck (2008), however, investigated whether chimpanzees were also able to prepare for a future exchange with a human: an object exchanged for a food item. The study included extensive training on the exchangeable item, which is traditionally not compatible with methods for studying planning abilities, as associative learning cannot be precluded. Nevertheless, despite this training, the chimpanzees could not solve the deferred exchange task. Given that great apes can plan for tool use, these results are puzzling. In addition, claims that great ape foresight is highly limited has been based on this study (Suddendorf and Corballis, 2010). Here we partly replicated Dufour and Sterck's study to discern whether temporally deferred and spatially displaced exchange tasks are beyond the capabilities of great apes. In addition to chimpanzees we tested orangutans. One condition followed the one used by Dufour and Sterck, in which the exchange items, functional only in the future, are placed at a location that freely allows for selections by the subjects. In order to test the possibility that the choice set-up could explain the negative results in Dufour and Sterck's study, our second condition followed a method used in the planning study by Osvath and Osvath (2008), where the subjects make a forced one-item-choice from a tray. We found that it is within the capabilities of chimpanzees and orangutans to perform deferred exchange in both conditions.

    2009-01-01

    BACKGROUND Deferral for travel to malaria-endemic areas excludes many blood donors in the United States. Most transfusion-transmitted malaria is associated with lengthy residence in malaria-endemic areas rather than routine travel. This study compares the impact of existing deferral requirements to the risk that a presenting donor with malaria travel history harbors malaria parasites under current and hypothetical alternate regulations. STUDY DESIGN AND METHODS Deferred donors from six blood centers were sampled to estimate a national cohort of donors deferred annually for malaria travel to different geographic regions. Risk for malaria infection following travel to each region, and distribution of incubation periods for each malaria species were estimated for U.S. travelers. Region-specific travel risks were used to estimate the risk that a presenting blood donor with malaria travel might asymptomatically harbor malaria parasites at different intervals following return to the United States. RESULTS Travel to Africa presents risk for malaria infection >1000 times that of travel to malaria-endemic parts of Mexico, yet Mexico accounts for >10 times as many deferred donors. Shortening the deferral period from 12 to 3 months for travelers to Mexico increases the risk of collecting a contaminated unit by only 1 unit per 57 years (sensitivity analysis, 1 every 29 - 114 years), at annual gain of >56,000 donations. CONCLUSION This study provides the first systematic appraisal of the U.S. requirements for donor qualification regarding travel to malarial areas. Consideration should be given to relaxing the guidelines for travel to very low-risk areas such as Mexico. PMID:19903290

    To date, mitochondrial DNA polymerase γ (POLG) is the only polymerase known to be present in mammalian mitochondria. A dogma in the mitochondria field is that there is no other polymerase present in the mitochondria of mammalian cells. Here we demonstrate localization of REV3 DNA polymerase in the mammalian mitochondria. We demonstrate localization of REV3 in the mitochondria of mammalian tissue as well as cell lines. REV3 associates with POLG and mitochondrial DNA and protects the mitochondrial genome from DNA damage. Inactivation of Rev3 leads to reduced mitochondrial membrane potential, reduced OXPHOS activity, and increased glucose consumption. Conversely, inhibition of the OXPHOS increases expression of Rev3. Rev3 expression is increased in human primary breast tumors and breast cancer cell lines. Inactivation of Rev3 decreases cell migration and invasion, and localization of Rev3 in mitochondria increases survival and the invasive potential of cancer cells. Taken together, we demonstrate that REV3 functions in mammalian mitochondria and that mitochondrial REV3 is associated with the tumorigenic potential of cells.

    Lung cancer remains the leading cause of cancer-related mortality worldwide and non-small cell lung cancer (NSCLC) accounts for approximately 80-85% of all cases of lung cancer. Cisplatin plays a significant role in the management of human lung cancer. Translesion DNA synthesis (TLS) is involved in DNA damage repair. DNA polymerase ζ (Pol ζ) is able to mediate the DNA replication bypass of DNA damage, which is suggested to be involved in chemoresistance. REV3L is the catalytic subunit of Pol ζ. Due to its critical role in translesion DNA synthesis, whether REV3L modulates cisplatin response in NSCLC cells remains unknown. In this study, REV3L overexpression and silencing H1299 cell lines were established. The reports showed that cisplatin induced the expression of REV3L by recruiting Sp1 to its promoter. Similar results were obtained when the ability of the cells to express luciferase from a platinated plasmid was measured. Co-transfection of the reporter with the REV3L overexpression vector or REV3L plus REV7L significantly enhanced the reporter activity. Nuclear condensation and fragmentation of shRNA-REV3L H1299 cells were more pronounced than shRNA-NC H1299 cells after cisplatin exposure, indicating that REV3L overexpression abolished cisplatin-induced DNA damage. Moreover, a forced expression of REV3L conferred the resistance of H1299 cells to cisplatin, whereas the knockdown of REV3L sensitized cisplatin efficacy in H1299 cells. Taken together, we demonstrated that inhibition of REV3L sensitized lung cancer H1299 cells to cisplatin treatment. Thus, REV3L may be a novel target for the chemotherapy of NSCLC.

    This study investigates spontaneous pretend play during a parent-child free play observation, and deferred imitation observed in an experimental setting in speaking and non-speaking children with autism in comparison to children with typical development. Both groups of children with autism showed a reduced level of deferred imitation compared to the typically developing group, but only the non-speaking children with autism spent significantly less time in pretend play compared to children with typical development. Deferred imitation was related to parents' verbal interaction in both groups. An analysis of the parent-child interaction revealed that parents of children with autism used less synchronized comments compared to parents of typically developing children. Parents of the speaking group with autism used more synchronized than unsynchronized comments, while parents of the non-speaking group used the same amount of synchronized and unsynchronized comments. These findings are discussed in terms of how the developmental level affects behavior and interaction in autism.

    Data on the clinical outcomes in deferred coronary lesions according to functional severity have been limited. This study evaluated the clinical outcomes of deferred lesions according to fractional flow reserve (FFR) grade using Korean FFR registry data. Among 1,294 patients and 1,628 lesions in Korean FFR registry, 665 patients with 781 deferred lesions were included in this study. All participants were consecutively categorized into 4 groups according to FFR; group 1: ≥ 0.96 (n = 56), group 2: 0.86-0.95 (n = 330), group 3: 0.81-0.85 (n = 170), and group 4: ≤ 0.80 (n = 99). Primary endpoint was major adverse cardiac events (MACE), a composite of all-cause death, myocardial infarction, and target vessel revascularization. The median follow-up period was 2.1 years. During follow-up, the incidence of MACE in groups 1-4 was 1.8%, 7.6%, 8.8%, and 13.1%, respectively. Compared to group 1, the cumulative rate by Kaplan-Meier analysis of MACE was not different for groups 2 and 3. However, group 4 had higher cumulative rate of MACE compared to group 1 (log-rank P = 0.013). In the multivariate Cox hazard models, only FFR (hazard ratio [HR], 0.95; P = 0.005) was independently associated with MACE among all participants. In contrast, previous history of percutaneous coronary intervention (HR, 2.37; P = 0.023) and diagnosis of acute coronary syndrome (ACS) (HR, 2.35; P = 0.015), but not FFR, were independent predictors for MACE in subjects with non-ischemic (FFR ≥ 0.81) deferred coronary lesions. Compared to subjects with ischemic deferred lesions, clinical outcomes in subjects with non-ischemic deferred lesions according to functional severity are favorable. However, longer-term follow-up may be necessary.

    2003-01-01

    Subsequent to the modifications to the Rules and Regulations of the Pension Fund allowing members of the personnel having five years of affiliation to the Fund to opt for a deferred retirement pension, the Organization wishes to recall the rules relating to the affiliation of those beneficiaries to the CERN Health Insurance Scheme (CHIS). In accordance with Articles III 2.02 and VIII 4.02 of the CHIS Rules, beneficiaries of a deferred retirement pension can only be Members of the CHIS as CERN pensioners if they applied to remain Members of the Scheme upon termination of their compulsory membership as a member of the personnel and if their membership has been uninterrupted up to the moment they become CERN pensioners. The applicable contribution for this intermediate period is indicated in Articles III 5.03 and X 1.02 of the CHIS Rules. The amount is revised annually, and is set at 936 CHF/ month for 2003.

    There are about 1.8 million young immigrants in the United States who came or were brought to the country without documentation before the age of 16. These youth have been raised and educated in the United States and have aspirations and educational achievements similar to those of their native-born peers. However, their undocumented status has hindered their pursuit of higher education, especially in medical and other graduate health sciences. Under a new discretionary policy, Deferred Action for Childhood Arrivals (DACA), many of these young immigrants are eligible to receive permission to reside and work in the United States. DACA defers deportation of eligible, undocumented youth and grants lawful presence in the United States, work permits, Social Security numbers, and, in most states, driver's licenses. These privileges have diminished the barriers undocumented students traditionally have faced in obtaining higher education, specifically in pursuing medicine. With the advent of DACA, students are slowly matriculating into U.S. medical schools and residencies. However, this applicant pool remains largely untapped. In the face of a physician shortage and the implementation of the Affordable Care Act, an increase in matriculation of qualified undocumented students would be greatly beneficial. This Perspective is intended to begin discussion within the academic medicine community of the implications of DACA in reducing barriers for the selection and matriculation of undocumented medical students and residents. Moreover, this Perspective is a call to peers in the medical community to support undocumented students seeking access to medical school, residency, and other health professions.

  16. Deference and Diffèrance: Judicial Review and the Perfect Gift

    2006-01-01

    Full Text Available The highest courts in both Canada and South Africa have expressed themselves in favour of an approach of deference as respect in the review of administrative action. The notion of deference as respect derives from the thinking of David Dyzenhaus, who has developed a theory of democracy in support of this approach to judicial review. Dyzenhaus’ model of review attempts to steer clear from the problems he associates particularly with positivism and liberalism. Dyzenhaus’ model of review furthermore attempts to allow space for the administration to play a significant role in giving effect to democratic values, on the understanding that all such decisions need to be reasonably justifiable. In this article the views of Dyzenhaus are contrasted with those of Jacques Derrida, especially insofar as the latter has reflected on the relation between law and justice, as well as concepts such as the gift and democracy. The argument developed in this article is that Dyzenhaus’ model of review, despite its many positive features, needs to be rethought with reference to the perfect gift, unconditional justice and democracy to come. Such a rethinking is required because of the limited conception of justice – as simply ‘our’ justice – in Dyzenhaus’ model.

    Full Text Available There has always been and will be a relationship between accounting and taxation, and the ongoing discussions are related to intensity, interrelation and generation of reciprocal effects. Profit is the "wealth" achieved by the economic entity, the share of shareholders after paying the income tax, where applicable, which makes the profit have a major influence on the method of determination and thus of the accounting treatment incurred by the income tax depending on the accounting cultures in dispute for supremacy, namely the European accounting culture and the Anglo-Saxon accounting culture. As the users of information in the financial statements seek to assess the performance and profitability of the company in general and, academically, the income tax is the only element raising debates on the relationship between accounting and taxation, we deemed it useful to conduct a study on the accounting – taxation report in terms of deferred taxes related to assets revaluation. The record of deferred tax amount for each type of temporary difference results in elimination of tax effects from accounting, with the aim of revealing the real earnings of the economic entity and not its fiscal side, all of which is a step in disconnecting the taxation accounting

    Full Text Available Abstract Background The optimal stage for initiating antiretroviral therapies in HIV-1 bearing patients is still a matter of debate. Methods We present computer simulations of HIV-1 infection aimed at identifying the pro et contra of immediate as compared to deferred Highly Active Antiretroviral Therapy (HAART. Results Our simulations highlight that a prompt specific CD8+ cytotoxic T lymphocytes response is detected when therapy is delayed. Compared to very early initiation of HAART, in deferred treated patients CD8+ T cells manage to mediate the decline of viremia in a shorter time and, at interruption of therapy, the virus experiences a stronger immune pressure. We also observe, however, that the immunological effects of the therapy fade with time in both therapeutic regimens. Thus, within one year from discontinuation, viral burden recovers to the value at which it would level off in the absence of therapy. In summary, simulations show that immediate therapy does not prolong the disease-free period and does not confer a survival benefit when compared to treatment started during the chronic infection phase. Conclusion Our conclusion is that, since there is no therapy to date that guarantees life-long protection, deferral of therapy should be preferred in order to minimize the risk of adverse effects, the occurrence of drug resistances and the costs of treatment.

  2. DDX5 facilitates HIV-1 replication as a cellular co-factor of Rev.

    Directory of Open Access Journals (Sweden)

    Xiuxia Zhou

    Full Text Available HIV-1 Rev plays an important role in the late phase of HIV-1 replication, which facilitates export of unspliced viral mRNAs from the nucleus to cytoplasm in infected cells. Recent studies have shown that DDX1 and DDX3 are co-factors of Rev for the export of HIV-1 transcripts. In this report, we have demonstrated that DDX5 (p68, which is a multifunctional DEAD-box RNA helicase, functions as a new cellular co-factor of HIV-1 Rev. We found that DDX5 affects Rev function through the Rev-RRE axis and subsequently enhances HIV-1 replication. Confocal microscopy and co-immunoprecipitation analysis indicated that DDX5 binds to Rev and this interaction is largely dependent on RNA. If the DEAD-box motif of DDX5 is mutated, DDX5 loses almost all of its ability to bind to Rev, indicating that the DEAD-box motif of DDX5 is required for the interaction between DDX5 and Rev. Our data indicate that interference of DDX5-Rev interaction could reduce HIV-1 replication and potentially provide a new molecular target for anti-HIV-1 therapeutics.

    DNA interstrand crosslink (ICL) repair (ICLR) has been implicated in the resistance of cancer cells to ICL-inducing chemotherapeutic agents. Despite the clinical significance of ICL-inducing chemotherapy, few studies have focused on developing small-molecule inhibitors for ICLR. The mammalian DNA polymerase ζ, which comprises the catalytic subunit REV3L and the non-catalytic subunit REV7, is essential for ICLR. To identify small-molecule compounds that are mechanistically capable of inhibiting ICLR by targeting REV7, high-throughput screening and structure-activity relationship (SAR) analysis were performed. Compound 1 was identified as an inhibitor of the interaction of REV7 with the REV7-binding sequence of REV3L. Compound 7 (an optimized analog of compound 1) bound directly to REV7 in nuclear magnetic resonance analyses, and inhibited the reactivation of a reporter plasmid containing an ICL in between the promoter and reporter regions. The normalized clonogenic survival of HeLa cells treated with cisplatin and compound 7 was lower than that for cells treated with cisplatin only. These findings indicate that a small-molecule inhibitor of the REV7/REV3L interaction can chemosensitize cells by inhibiting ICLR.

    Immediate delivery of the preterm fetus with suspected compromise may decrease the risk of damage due to intrauterine hypoxia. However, it may also increase the risks of prematurity. To assess the effects of immediate versus deferred delivery of preterm babies with suspected fetal compromise on neonatal, maternal and long-term outcomes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2016) and reference lists of retrieved studies. Randomised trials comparing a policy of immediate delivery with deferred delivery or expectant management in preterm fetuses with suspected in utero compromise. Quasi-randomised trials and trials employing a cluster-randomised design were eligible for inclusion but none were identified. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. We included one trial of 548 women (588 babies) in the review. Women with pregnancies between 24 and 36 weeks' gestation took part. The study took place in 13 European countries, between 1993 and 2001. The difference in the median randomisation to delivery interval between immediate delivery and deferred delivery was four days (median: 0.9 (inter-quartile range (IQR) 0.4 to 1.3) days for immediate delivery, median: 4.9 (IQR 2.0 to 10.8) days in the delay group).There was no clear difference in the primary outcomes of extended perinatal mortality (risk ratio (RR) 1.17, 95% confidence interval (CI) 0.67 to 2.04, one trial, 587 babies, moderate-quality evidence) or the composite outcome of death or disability at or after two years of age (RR 1.22, 95% CI 0.85 to 1.75, one trial, 573 babies, moderate-quality evidence) with immediate delivery compared to deferred delivery. The results for these outcomes are consistent with both appreciable benefit and harm. More babies in the immediate delivery group were ventilated for more than 24 hours (RR 1.54, 95% CI 1.20 to 1.97, one trial, 576 babies). There

    Mutations arising in times of cell cycle arrest may provide a selective advantage for unicellular organisms adapting to environmental changes. For multicellular organisms, however, they may pose a serious threat, in that such mutations in somatic cells contribute to carcinogenesis and ageing. The budding yeast Saccharomyces cerevisiae presents a convenient model system for studying the incidence and the mechanisms of stationary-phase mutation in a eukaryotic organism. Having studied the emergence of frameshift mutants after several days of starvation-induced cell cycle arrest, we previously reported that all (potentially error-prone) translesion synthesis (TLS) enzymes identified in S. cerevisiae did not contribute to the basal level of spontaneous stationary-phase mutations. However, we observed that an increased frequency of stationary-phase frameshift mutations, brought about by a defective nucleotide excision repair (NER) pathway or by UV irradiation, was dependent on Rev3p, the catalytic subunit of the TLS polymerase zeta (Pol {zeta}). Employing the same two conditions, we now examined the effect of deletions of the genes coding for polymerase eta (Pol {eta}) (RAD30) and Rev1p (REV1). In a NER-deficient strain background, the increased incidence of stationary-phase mutations was only moderately influenced by a lack of Pol {eta} but completely reduced to wild type level by a knockout of the REV1 gene. UV-induced stationary-phase mutations were abundant in wild type and rad30{delta} strains, but substantially reduced in a rev1{delta} as well as a rev3{delta} strain. The similarity of the rev1{delta} and the rev3{delta} phenotype and an epistatic relationship evident from experiments with a double-deficient strain suggests a participation of Rev1p and Rev3p in the same mutagenic pathway. Based on these results, we propose that the response of cell cycle-arrested cells to an excess of exo- or endogenously induced DNA damage includes a novel replication

  6. Wind Farm Wake: The Horns Rev Photo Case

    2013-02-01

    Full Text Available The aim of the paper is to examine the nowadays well-known wind farm wake photographs taken on 12 February 2008 at the offshore Horns Rev 1 wind farm. The meteorological conditions are described from observations from several satellite sensors quantifying clouds, surface wind vectors and sea surface temperature as well as ground-based information at and near the wind farm, including Supervisory Control and Data Acquisition (SCADA data. The SCADA data reveal that the case of fog formation occurred 12 February 2008 on the 10:10 UTC. The fog formation is due to very special atmospheric conditions where a layer of cold humid air above a warmer sea surface re-condensates to fog in the wake of the turbines. The process is fed by warm humid air up-drafted from below in the counter-rotating swirl generated by the clock-wise rotating rotors. The condensation appears to take place primarily in the wake regions with relatively high axial velocities and high turbulent kinetic energy. The wind speed is near cut-in and most turbines produce very little power. The rotational pattern of spiraling bands produces the large-scale structure of the wake fog.

  7. H-rev107 Regulates Cytochrome P450 Reductase Activity and Increases Lipid Accumulation.

    Directory of Open Access Journals (Sweden)

    Full Text Available H-rev107 is a member of the HREV107 type II tumor suppressor gene family and acts as a phospholipase to catalyze the release of fatty acids from glycerophospholipid. H-rev107 has been shown to play an important role in fat metabolism in adipocytes through the PGE2/cAMP pathway, but the detailed molecular mechanism underlying H-rev107-mediated lipid degradation has not been studied. In this study, the interaction between H-rev107 and cytochrome P450 reductase (POR, which is involved in hepatic lipid content regulation, was determined by yeast two-hybrid screen and confirmed by using in vitro pull down assays and immunofluorescent staining. The expression of POR in H-rev107-expressing cells enhanced the H-rev107-mediated release of arachidonic acid. However, H-rev107 inhibited POR activity and relieved POR-mediated decreased triglyceride content in HtTA and HeLa cervical cells. The inhibitory effect of H-rev107 will be abolished when POR-expressing cells transfected with PLA2-lacking pH-rev107 or treated with PLA2 inhibitor. Silencing of H-rev107 using siRNA resulted in increased glycerol production and reversion of free fatty acid-mediated growth suppression in Huh7 hepatic cells. In summary, our results revealed that H-rev107 is also involved in lipid accumulation in liver cells through the POR pathway via its PLA2 activity.

  17. Pharmacological and Genetic Modulation of REV-ERB Activity and Expression Affects Orexigenic Gene Expression.

    Directory of Open Access Journals (Sweden)

    Ariadna Amador

    Full Text Available The nuclear receptors REV-ERBα and REV-ERBβ are transcription factors that play pivotal roles in the regulation of the circadian rhythm and various metabolic processes. The circadian rhythm is an endogenous mechanism, which generates entrainable biological changes that follow a 24-hour period. It regulates a number of physiological processes, including sleep/wakeful cycles and feeding behaviors. We recently demonstrated that REV-ERB-specific small molecules affect sleep and anxiety. The orexinergic system also plays a significant role in mammalian physiology and behavior, including the regulation of sleep and food intake. Importantly, orexin genes are expressed in a circadian manner. Given these overlaps in function and circadian expression, we wanted to determine whether the REV-ERBs might regulate orexin. We found that acute in vivo modulation of REV-ERB activity, with the REV-ERB-specific synthetic ligand SR9009, affects the circadian expression of orexinergic genes in mice. Long term dosing with SR9009 also suppresses orexinergic gene expression in mice. Finally, REV-ERBβ-deficient mice present with increased orexinergic transcripts. These data suggest that the REV-ERBs may be involved in the repression of orexinergic gene expression.

    Human immunodeficiency virus gene expression and replication are regulated at several levels. Incompletely spliced viral RNAs and full-length genomic RNA contain the RRE element and are bound by the viral trans-acting protein Rev to be transported out of the nucleus. Previously we found that the nuclear matrix protein MATR3 was a cofactor of Rev-mediated RNA export. Here we show that the pleiotropic protein PSF binds viral RNA and is associated with MATR3. PSF is involved in the maintenance of a pool of RNA available for Rev activity. However, while Rev and PSF bind the viral pre-mRNA at the site of viral transcription, MATR3 interacts at a subsequent step. We propose that PSF and MATR3 define a novel pathway for RRE-containing HIV-1 RNAs that is hijacked by the viral Rev protein.

  19. Deferred Action: Theoretical model of process architecture design for emergent business processes

    Directory of Open Access Journals (Sweden)

    Patel, N.V.

    2007-01-01

    Full Text Available E-Business modelling and ebusiness systems development assumes fixed company resources, structures, and business processes. Empirical and theoretical evidence suggests that company resources and structures are emergent rather than fixed. Planning business activity in emergent contexts requires flexible ebusiness models based on better management theories and models . This paper builds and proposes a theoretical model of ebusiness systems capable of catering for emergent factors that affect business processes. Drawing on development of theories of the ‘action and design’class the Theory of Deferred Action is invoked as the base theory for the theoretical model. A theoretical model of flexible process architecture is presented by identifying its core components and their relationships, and then illustrated with exemplar flexible process architectures capable of responding to emergent factors. Managerial implications of the model are considered and the model’s generic applicability is discussed.

    Malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The present study aimed for the first time, to investigate malaria in "donors deferred for malaria risk" and to determine the regional rates of malaria deferral in Turkey. Blood samples were collected from several Blood Banks of southeastern provinces where local malaria cases still exist and from Blood Bank of Ege University Medical School (EUMS) located in western Turkey where malaria is eradicated decades ago. Plasmodium spp. and specific antibodies were investigated by stained smears, antigen detection, PCR and ELISA. Among the donors deferred for malaria risk, Plasmodium spp. were not detected by microscopy, PCR or antigen detection. Seroprevalances were 2% and 3.92% in western and southeastern regions, respectively. Rate of donor deferral for malaria risk was 0.9% in EUMS and deferrals were exclusively because of travel to southeastern Turkey. In southeastern provinces, deferrals were mainly due to malaria like fever history. The present study first time assessed regional rates of donor deferral due to malaria risk in Turkey. Previously, malaria was expected to be a major problem during blood donation in Turkey due to existence of malaria cases in southeastern region of Turkey. The results of the study showed that 97% of the deferrals were unnecessary. In conclusion, to reduce unnecessary donor deferrals in Turkey, in addition to comprehensive questioning for malaria history, the usage of a malaria antibody screening method should be initiated prior to deferral decision.

    Background More than 66,000 blood donors are deferred annually in the U.S. due to travel to malaria-endemic areas of Mexico. Mexico accounts for the largest share of malaria travel deferrals, yet it has extremely low risk for malaria transmission throughout most of its national territory, suggesting a suboptimal balance between blood safety and availability. This study sought to determine whether donor deferral requirements might be relaxed for parts of Mexico without compromising blood safety. Study Design and Methods Travel destination was recorded from a representative sample of presenting blood donors deferred for malaria travel from six blood centers during 2006. We imputed to these donors reporting Mexican travel a risk for acquiring malaria equivalent to Mexican residents in the destination location, adjusted for length of stay. We extrapolated these results to the overall U.S. blood donor population. Results Risk for malaria in Mexico varies significantly across endemic areas and is greatest in areas infrequently visited by study donors. Over 70% of blood donor deferrals were triggered by travel to the state of Quintana Roo on the Yucatán Peninsula, an area of very low malaria transmission. Eliminating the travel deferral requirement for all areas except the state of Oaxaca might result in the recovery of almost 65,000 blood donors annually at risk of approximately one contaminated unit collected every 20 years. Conclusion Deferral requirements should be relaxed for presenting donors who travelled to areas within Mexico that confer exceptionally small risks for malaria, such as Quintana Roo. PMID:21564102

    Full Text Available The aim this work was to evaluate the morphogenic and structural characteristics of Brachiaria decumbens pastures to determine the most suitable nitrogen fertilization strategies, for pastures deferred for a period of 95 days. Four strategies of fertilization at the beginning and end of the summer (0-0, 100- 0, 50-50, 0-100 kg ha-1 N were studied, respectively, with four replications. The strategy of 100 kg ha-1 N applied at the end of the summer (0-100, followed the parceling strategy at the beginning and end of the summer (50-50 favored higher rates of leaf appearance and lower values of phyllochron. Greater rate of leaf elongation was observed for 0-100 strategy, resulting in 40% increase compared to pastures that were not fertilized. However, there was no effect of fertilization strategies on stem elongation rate, registering an average of 0.28 cm.dia-1. There was a higher blade:stem ratio for the stratum A (40 cm above the soil in all treatments, observing higher blade:stem ratio for strategies 0-100 and 50-50, at this stratum. There was no effect for the total number of leaves and final leaf length. However, greater stem lengths were observed in pastures with 0-100 fertilizer strategy, followed by the 50-50 strategy. The strategy of applying 100 kg ha-1 at the end of summer, followed by the strategy of 50 kg ha-1 nitrogen divided at the beginning and end of summer, promote greater influence on the morphogenic and structural traits, in pastures deferred for 95 days.

    Rev1 is a member of the Y-family of DNA polymerases and is known for its deoxycytidyl transferase activity that incorporates dCMP into DNA and its ability to function as a scaffold factor for other Y-family polymerases in translesion bypass events. Rev1 also is involved in mutagenic processes during somatic hypermutation of immunoglobulin genes. In light of the mutation pattern consistent with dCMP insertion observed earlier in mouse fibroblast cells treated with a base excision repair-inducing agent, we questioned whether Rev1 could also be involved in base excision repair (BER). Here, we uncovered a weak 5′-deoxyribose phosphate (5′-dRP) lyase activity in mouse Rev1 and demonstrated the enzyme can mediate BER in vitro. The full-length Rev1 protein and its catalytic core domain are similar in their ability to support BER in vitro. The dRP lyase activity in both of these proteins was confirmed by NaBH4 reduction of the Schiff base intermediate and kinetics studies. Limited proteolysis, mass spectrometry and deletion analysis localized the dRP lyase active site to the C-terminal segment of Rev1's catalytic core domain. These results suggest that Rev1 could serve as a backup polymerase in BER and could potentially contribute to AID-initiated antibody diversification through this activity. PMID:27683219

  4. Rev1, Rev3, or Rev7 siRNA Abolishes Ultraviolet Light-Induced Translesion Replication in HeLa Cells: A Comprehensive Study Using Alkaline Sucrose Density Gradient Sedimentation

    Full Text Available When a replicative DNA polymerase stalls upon encountering a lesion on the template strand, it is relieved by other low-processivity polymerase(s, which insert nucleotide(s opposite the lesion, extend by a few nucleotides, and dissociate from the 3′-OH. The replicative polymerase then resumes DNA synthesis. This process, termed translesion replication (TLS or replicative bypass, may involve at least five different polymerases in mammals, although the participating polymerases and their roles have not been entirely characterized. Using siRNAs originally designed and an alkaline sucrose density gradient sedimentation technique, we verified the involvement of several polymerases in ultraviolet (UV light-induced TLS in HeLa cells. First, siRNAs to Rev3 or Rev7 largely abolished UV-TLS, suggesting that these 2 gene products, which comprise Polζ, play a main role in mutagenic TLS. Second, Rev1-targeted siRNA also abrogated UV-TLS, indicating that Rev1 is also indispensable to mutagenic TLS. Third, Polη-targeted siRNA also prevented TLS to a greater extent than our expectations. Forth, although siRNA to Polι had no detectable effect, that to Polκ delayed UV-TLS. To our knowledge, this is the first study reporting apparent evidence for the participation of Polκ in UV-TLS.

    The nuclear hormone receptor, Rev-erb beta operates as a transcriptional silencer. We previously demonstrated that exogenous expression of Rev-erb{beta}{Delta}E in skeletal muscle cells increased Srebp-1c mRNA expression. We validated these in vitro observations by injection of an expression vector driving Rev-erb{beta}{Delta}E expression into mouse tibialis muscle that resulted in increased Srebp-1c mRNA expression. Paradoxically, Rev-erb{beta} siRNA expression in skeletal muscle cells repressed Srebp-1c expression, and indicated that Rev-erb{beta} expression was necessary for Srebp-1c expression. ChIP analysis demonstrated that Rev-erb{beta} was recruited to the Srebp-1c promoter. Moreover, Rev-erb{beta} trans-activated the Srebp-1c promoter, in contrast, Rev-erb{beta} efficiently repressed the Rev-erb{alpha} promoter, a previously characterized target gene. Finally, treatment with the Rev-erb agonist (hemin) (i) increased the trans-activation of the Srebp-1c promoter by Rev-erb{beta}; and (ii) increased Rev-erb{beta} and Srebp-1c mRNA expression. These data suggest that Rev-erb{beta} has the potential to activate gene expression, and is a positive regulator of Srebp-1c, a regulator of lipogenesis.

    Full Text Available The aim of this study was to examine the changes in the indicators of free radicals and antioxidant activity, represented by malondialdehyde and glutathione peroxidase in the sera of ewes vaccinated with Rev 1 vaccine. The experiment included 28 animals which were divided into four equal groups. Animals of the first and second groups were vaccinated subcutaneously with 2×109 and 2×107 colony forming units (CFU, respectively, whereas the animals of third and fourth groups were vaccinated conjunctively with 2×109 and 2×107 CFU, respectively. Sera were collected monthly for 6 months. Antibody responses were assessed by classical tests (Rose Bengal test, tube agglutination and 2-mercaptoethanol tests in comparison with competitive ELISA. The antibody titers were higher and remained for along period in the subcutaneously vaccinated groups with the two doses compared those vaccinated conjunctively. There was a significant increase in serum glutathione peroxidase activity in the 8th week post vaccination in subcutaneously vaccinated groups and during the 12th week in those vaccinated conjunctively. Significant increase of serum malondialdehyde levels occurred during the 4th week in those vaccinated conjunctively and in 8th week in those vaccinated subcutaneously. This study concluded that the route of administration of the vaccine affects glutathione peroxidase activity and malondialdehyde level, which act as indicators of oxidative stress response, more than the vaccine dose.

  11. Means And Ends In City Of Arlington v. FCC: Ignoring The Lawyer's Craft to Reshape the Scope of Chevron Deference

    Directory of Open Access Journals (Sweden)

    Michael P. Healy

    2015-07-01

    Full Text Available In last year’s term, the United States Supreme Court considered the question of the scope of Chevron deference in City of Arlington v. FCC. This article discusses how the decision is an example of the work of an activist Court. The case should have been resolved by a straight forward determination under the analysis of United States v. Mead that Chevron deference simply did not apply to the Federal Communications Commission’s (“FCC” legal determination. The Court ignored this restrained approach to the case and instead addressed the question the Justices desired to decide: the reach of Chevron deference. The article discusses and criticizes the approach of Justice Scalia writing for the majority and of Chief Justice Roberts writing for three dissenting Justices.Practitioners and scholars of administrative law can only be confused by the Court’s willingness to apply Chevron in City of Arlington, given the informal administrative action being reviewed and the fact that neither reviewing court actually applied each of the two parts of the Mead test. The Court’s flawed administrative law analysis results from the activist concerns of Justice Scalia and Chief Justice Roberts. Justice Scalia uses the case as a vehicle to undermine Mead, a decision that Justice Scalia loathes. Chief Justice Roberts uses the case as a vehicle to advocate for less judicial deference and less law defining power for increasingly powerful agencies. Neither member of the Court allowed the applicable rules of contemporary administrative law to hinder his efforts to achieve his broader goals. Administrative law would have been better served if a properly restrained Court had considered and applied the previously determined rules for judicial review of administrative agencies.

    Minjie Gao

    Full Text Available Whether patients with smoldering multiple myeloma (SMM needed to receive early interventional treatment remains controversial. Herein, we conducted a meta-analysis comparing the efficacy and safety of early treatment over deferred treatment for patients with SMM.MEDLINE and Cochrane Library were searched to May 2014 for randomized controlled trials (RCTs that assessed the effect of early treatment over deferred treatment. Primary outcome measure was mortality, and secondary outcome measures were progression, response rate, and adverse events.Overall, 5 trials including 449 patients were identified. There was a markedly reduced risk of disease progression with early treatment (Odds Ratio [OR] = 0.13, 95% confidence interval [CI] = 0.07 to 0.24. There were no significant differences in mortality and response rate (OR = 0.85, 95% CI = 0.45 to 1.60, and OR = 0.63, 95% CI = 0.32 to 1.23, respectively. More patients in the early treatment arm experienced gastrointestinal toxicities (OR = 10.02, 95%CI = 4.32 to 23.23, constipation (OR = 8.58, 95%CI = 3.20 to 23.00 and fatigue or asthenia (OR = 2.72, 95%CI = 1.30 to 5.67. No significant differences were seen with the development of acute leukemia (OR = 2.80, 95%CI = 0.42 to 18.81, hematologic cancer (OR = 2.07, 95%CI = 0.43 to 10.01, second primary tumors (OR = 3.45, 95%CI = 0.81 to 14.68, nor vertebral compression (OR = 0.18, 95%CI = 0.02 to 1.59.Early treatment delayed disease progression but increased the risk of gastrointestinal toxicities, constipation and fatigue or asthenia. The differences on vertebral compression, acute leukemia, hematological cancer and second primary tumors were not statistically significant. Based on the current evidence, early treatment didn't significantly affect mortality and response rate. However, further much larger trials were needed to provide more evidence.

    parameters and the geometric scaling parameters can really describe the gas thermal blooming effect in the axial pipe flow. These conclusions can give a good reference for the construction of the thermal blooming test system of laser system. Contrasted with the thermal blooming scaling parameters of the Bradley-Hermann distortion number ND and Fresnel number NF, which were derived based on the change of far field beam intensity distortion, the scaling parameters of pipe flow thermal blooming deduced from the optical path deference variation are very suitable for the optical system with short laser propagation distance, large Fresnel number and obviously changed optical path deference.

  20. Unperturbed posttranscriptional regulatory Rev protein function and HIV-1 replication in astrocytes.

    Directory of Open Access Journals (Sweden)

    Ashok Chauhan

    Full Text Available Astrocytes protect neurons, but also evoke proinflammatory responses to injury and viral infections, including HIV. There is a prevailing notion that HIV-1 Rev protein function in astrocytes is perturbed, leading to restricted viral replication. In earlier studies, our finding of restricted viral entry into astrocytes led us to investigate whether there are any intracellular restrictions, including crippled Rev function, in astrocytes. Despite barely detectable levels of DDX3 (Rev-supporting RNA helicase and TRBP (anti-PKR in primary astrocytes compared to astrocytic cells, Rev function was unperturbed in wild-type, but not DDX3-ablated astrocytes. As in permissive cells, after HIV-1 entry bypass in astrocytes, viral-encoded Tat and Rev proteins had robust regulatory activities, leading to efficient viral replication. Productive HIV-1 infection in astrocytes persisted for several weeks. Our findings on HIV-1 entry bypass in astrocytes demonstrated that the intracellular environment is conducive to viral replication and that Tat and Rev functions are unperturbed.

Method:A total of 74 cases with STEMI were selected, who had been given PCT thrombus aspiration surgery treatment, and were randomly divided into direct group and deferred group (n=37). Patients in direct group were given direct stent implantation surgery after PCT thrombus aspiration surgery treatment. Patients in deferred group were given deferred stent implantation surgery 14 d later after anticoagulant and anti-platelet treatment. Heart structure and function, stent release characteristics and adverse reactions) were compared 6 months after the surgery. Results:Two hours after surgery, ST segment drop amplitude in deferred group was significantly higher than that in direct group (P<0.05);TIMI frame number was obvious and no reflow/slow blood flow occurrence ratio was significantly lower than that in direct group (P<0.05);implantation stent number and stent length in deferred group were significantly less than that in direct group (P<0.05);the release characteristic indexes of implantation stent in deferred group:stent diameter and stent expansion pressure were significantly higher than that in direct group (P<0.05);6 months after surgery, LVEF improvement in deferred group was significantly higher than that in direct group (P<0.05), while LVEDD、LVEDV ventricular remodeling was significantly lower than that in direct group (P<0.05);The total adverse event occurrence rate in deferred group was 5.4%, which was significantly lower than that in direct group (18.9%) (P<0.05). Conclusions:The deferred stent implantation surgery after PCI thrombus aspiration surgery could obviously reduce the occurrence rate of no reflow/slow blood flow, obviously improve the heart function and myocardial perfusion, reduce the usage amount of stent, reduce the occurrence of

    As a result of the Danish Government's Energy Plan 21 a target of 5,500 MW wind power is to be erected in Denmark by 2030. 4,000 MW of these are to be placed offshore in special pointed areas with minimal impacts on the environment. In 1998 the Danish Ministry of Environment and Energy ordered two power companies, Elsam and Energi E2, to establish each a demonstration wind farm at one of the five pointed areas. The intention was to follow the environmental impacts from the wind farm and to evaluate the possibility of setting up about 1,500 MW in each area with as little impact on the environment as possible. In 1999 the two power companies were given approval to begin pre-studies of each of the two wind farms and the work on the site construction as well as the environmental impact assessment related hereto was initiated. The authorities made a number of requirements for the EIA surveys according to the EU-directive for preparation of EIA reports. In the summer of 2000 the EIA report with project description was submitted to the authorities and the project was approved in the spring of 2001. During the summer and autumn of 2001 orders were placed for the components for the wind farm, i.e. foundations, towers, wind turbines, cables etc. After having finalised the EIA, monitoring programmes of the wind farms were initiated on basis of the results of the surveys carried out during the EIA. This means that continuous surveys have been implemented for most of the environmental parameters from 1999 and till today. This annual status report for 2001 is to present the results from the annual environmental monitoring programme (the baseline studies) at Horns Rev, which form part of the monitoring programme set up for the Horns Rev project. To get a complete picture of the Danish monitoring programme for the national demonstration wind farm project it is necessary to see the report for Horns Rev and for Roedsand as a whole. The report comprises a description of the wind

    Full Text Available Surgical resection for well-selected patients with refractory epilepsy provides seizure freedom approximately two-thirds of the time. Despite this, many good candidates for surgery, after a presurgical workup, ultimately do not consent to a procedure. The reasons why patients decline potentially effective surgery are not completely understood. We explored the socio cultural, medical, personal, and psychological differences between candidates who chose (n = 23 and those who declined surgical intervention (n = 9. We created a novel questionnaire addressing a range of possible factors important in patient decision making. We found that patients who declined surgery were less bothered by their epilepsy (despite comparable severity, more anxious about surgery, and less likely to listen to their doctors (and others and had more comorbid psychiatric disease. Patients who chose surgery were more embarrassed by their seizures, more interested in being “seizure-free”, and less anxious about specific aspects of surgery. Patient attitudes, beliefs, and anxiety serve as barriers to ideal care. These results can provide opportunities for education, treatment, and intervention. Additionally, patients who fit a profile of someone who is likely to defer surgery may not be appropriate for risky and expensive presurgical testing.

Patients were divided into 2 groups: those with ≥1 remaining FFR-negative (>0.80) medically treated lesions [FFR(-)MT] and those with only FFR-positive lesions (≤0.80) who underwent complete revascularization [FFR(+)CR] and were followed until July 1, 2015. The primary end point was the incidence of major adverse cardiovascular events (MACE), a composite of death, myocardial infarction (MI), target lesion (FFR assessed) revascularization, and rehospitalization for acute coronary syndrome. A total of 294 patients, 205 (69.7%) versus 89 (30.3%) in FFR(-)MT and FFR(+)CR, respectively, were analyzed. At a mean follow-up of 32.6 ± 18.1 months, FFR(-)MT was associated with higher MACE rate 44.0% versus 26.6% (log-rank p = 0.02, Cox regression-adjusted hazard ratio [HR] 2.01, 95% confidence interval [CI] 1.21 to 3.33, p required to guide our treatment strategy in these patients with high-risk, fast-progressing atherosclerosis.

    A first-person-shooter video game was adapted for the study of choice between smaller sooner and larger later outcomes to compare the behavioral patterns produced by deferred gratification (DG) and delay discounting (DD) tasks. Participants played a game in which they could either fire their weapon sooner and do a small amount of damage or wait a few seconds to fire their weapon and do a larger amount of damage. For the DD task, a failure to fire within one second committed the player to waiting for the larger later outcome thus removing the opportunity to defect during the delay that is present in the DG task. The incentive structure changed multiple times during game play so that at times the optimal decision was to choose the smaller sooner outcome whereas at other times the optimal decision was to wait for the larger later outcome. Players assigned to the DD task showed a greater tendency to wait and lower sensitivity to the changing incentives.

    Surgical resection for well-selected patients with refractory epilepsy provides seizure freedom approximately two-thirds of the time. Despite this, many good candidates for surgery, after a presurgical workup, ultimately do not consent to a procedure. The reasons why patients decline potentially effective surgery are not completely understood. We explored the socio cultural, medical, personal, and psychological differences between candidates who chose (n = 23) and those who declined surgical intervention (n = 9). We created a novel questionnaire addressing a range of possible factors important in patient decision making. We found that patients who declined surgery were less bothered by their epilepsy (despite comparable severity), more anxious about surgery, and less likely to listen to their doctors (and others) and had more comorbid psychiatric disease. Patients who chose surgery were more embarrassed by their seizures, more interested in being "seizure-free", and less anxious about specific aspects of surgery. Patient attitudes, beliefs, and anxiety serve as barriers to ideal care. These results can provide opportunities for education, treatment, and intervention. Additionally, patients who fit a profile of someone who is likely to defer surgery may not be appropriate for risky and expensive presurgical testing.

  12. Direct and Indirect Suppression of Interleukin-6 Gene Expression in Murine Macrophages by Nuclear Orphan Receptor REV-ERBα

    Full Text Available It is now evident that many nuclear hormone receptors can modulate target gene expression. REV-ERBα, one of the nuclear hormone receptors with the capacity to alter clock function, is critically involved in lipid metabolism, adipogenesis, and the inflammatory response. Recent studies suggest that REV-ERBα plays a key role in the mediation between clockwork and inflammation. The purpose of the current study was to investigate the role of REV-ERBα in the regulation of interleukin-6 (il6 gene expression in murine macrophages. REV-ERBα agonists, or overexpression of rev-erbα in the murine macrophage cell line RAW264 cells, suppressed the induction of il6 mRNA following a lipopolysaccharide (LPS endotoxin challenge. Also, rev-erbα overexpression decreased LPS-stimulated nuclear factor κB (NFκB activation in RAW264 cells. We showed that REV-ERBα represses il6 expression not only indirectly through an NFκB binding motif but also directly through a REV-ERBα binding motif in the murine il6 promoter region. Furthermore, peritoneal macrophages from mice lacking rev-erbα increased il6 mRNA expression. These data suggest that REV-ERBα regulates the inflammatory response of macrophages through the suppression of il6 expression. REV-ERBα may therefore be identified as a potent anti-inflammatory receptor and be a therapeutic target receptor of inflammatory diseases.

  13. Nullbasic, a potent anti-HIV tat mutant, induces CRM1-dependent disruption of HIV rev trafficking.

    Directory of Open Access Journals (Sweden)

    Min-Hsuan Lin

    Full Text Available Nullbasic, a mutant of the HIV-1 Tat protein, has anti-HIV-1 activity through mechanisms that include inhibition of Rev function and redistribution of the HIV-1 Rev protein from the nucleolus to the nucleoplasm and cytoplasm. Here we investigate the mechanism of this effect for the first time, establishing that redistribution of Rev by Nullbasic is not due to direct interaction between the two proteins. Rather, Nullbasic affects subcellular localization of cellular proteins that regulate Rev trafficking. In particular, Nullbasic induced redistribution of exportin 1 (CRM1, nucleophosmin (B23 and nucleolin (C23 from the nucleolus to the nucleus when Rev was coexpressed, but never in its absence. Inhibition of the Rev:CRM1 interaction by leptomycin B or a non-interacting RevM10 mutant completely blocked redistribution of Rev by Nullbasic. Finally, Nullbasic did not inhibit importin β- or transportin 1-mediated nuclear import, suggesting that cytoplasmic accumulation of Rev was due to increased export by CRM1. Overall, our data support the conclusion that CRM1-dependent subcellular redistribution of Rev from the nucleolus by Nullbasic is not through general perturbation of either nuclear import or export. Rather, Nullbasic appears to interact with and disrupt specific components of a Rev trafficking complex required for its nucleocytoplasmic shuttling and, in particular, its nucleolar accumulation.

    REV-ERBα has been shown to regulate adipogenesis and lipid metabolism as well as to link the circadian timing system to whole body metabolic homeostasis. We thus tested whether polymorphisms in REV-ERBα could be associated with metabolic phenotypes in human population samples. We analyzed the associations between 5 REV-ERBα polymorphisms and anthropometric (body weight, body mass index (BMI), waist and hip circumferences), biochemical (plasma lipid, glucose and insulin levels) and clinical (systolic and diastolic blood pressure) variables in three population-based studies (MONICA Lille n=1155 adults, MONA LISA Lille n=1170 adults and HELENA n=1155 adolescents). We assessed in vitro, the potential influence of one REV-ERBα polymorphism in transient transfection assays using two different cell lines. We observed significant and consistent associations between the T minor allele of the REV-ERBα rs2071427 polymorphism (located in intron 1) and higher BMI (mean allele effect=+0.33 kg m(-2)) in the MONICA Lille (P=0.02), MONA LISA (P=0.02) and HELENA (P=0.03) studies. The odds ratios for obesity associated with this allele were 1.67 (1.00-2.79) (P=0.05) in MONICA Lille, 1.29 (1.01-1.65) (P=0.04) in MONA LISA Lille and the odds ratio for overweight was 1.48 (1.08-2.03) (P=0.01) in HELENA. In transfection experiments in human hepatocyte-derived cell lines, the REV-ERBα intron 1 directed the transcription of a luciferase reporter gene independently of the rs2071427 polymorphism. Our results suggest that the REV-ERBα rs2071427 polymorphism modulates body fat mass in both adult and young people.

  16. REV-ERBalpha participates in circadian SREBP signaling and bile acid homeostasis.

    Full Text Available In mammals, many aspects of behavior and physiology, and in particular cellular metabolism, are coordinated by the circadian timing system. Molecular clocks are thought to rely on negative feedback loops in clock gene expression that engender oscillations in the accumulation of transcriptional regulatory proteins, such as the orphan receptor REV-ERBalpha. Circadian transcription factors then drive daily rhythms in the expression of clock-controlled output genes, for example genes encoding enzymes and regulators of cellular metabolism. To gain insight into clock output functions of REV-ERBalpha, we carried out genome-wide transcriptome profiling experiments with liver RNA from wild-type mice, Rev-erbalpha knock-out mice, or REV-ERBalpha overexpressing mice. On the basis of these genetic loss- and gain-of-function experiments, we concluded that REV-ERBalpha participates in the circadian modulation of sterol regulatory element-binding protein (SREBP activity, and thereby in the daily expression of SREBP target genes involved in cholesterol and lipid metabolism. This control is exerted via the cyclic transcription of Insig2, encoding a trans-membrane protein that sequesters SREBP proteins to the endoplasmic reticulum membranes and thereby interferes with the proteolytic activation of SREBPs in Golgi membranes. REV-ERBalpha also participates in the cyclic expression of cholesterol-7alpha-hydroxylase (CYP7A1, the rate-limiting enzyme in converting cholesterol to bile acids. Our findings suggest that this control acts via the stimulation of LXR nuclear receptors by cyclically produced oxysterols. In conclusion, our study suggests that rhythmic cholesterol and bile acid metabolism is not just driven by alternating feeding-fasting cycles, but also by REV-ERBalpha, a component of the circadian clockwork circuitry.

  17. Nuclear Factor 90, a cellular dsRNA binding protein inhibits the HIV Rev-export function

    2006-11-01

    Full Text Available Abstract Background The HIV Rev protein is known to facilitate export of incompletely spliced and unspliced viral transcripts to the cytoplasm, a necessary step in virus life cycle. The Rev-mediated nucleo-cytoplasmic transport of nascent viral transcripts, dependents on interaction of Rev with the RRE RNA structural element present in the target RNAs. The C-terminal variant of dsRNA-binding nuclear protein 90 (NF90ctv has been shown to markedly attenuate viral replication in stably transduced HIV-1 target cell line. Here we examined a mechanism of interference of viral life cycle involving Rev-NF90ctv interaction. Results Since Rev:RRE complex formations depend on protein:RNA and protein:protein interactions, we investigated whether the expression of NF90ctv might interfere with Rev-mediated export of RRE-containing transcripts. When HeLa cells expressed both NF90ctv and Rev protein, we observed that NF90ctv inhibited the Rev-mediated RNA transport. In particular, three regions of NF90ctv protein are involved in blocking Rev function. Moreover, interaction of NF90ctv with the RRE RNA resulted in the expression of a reporter protein coding sequences linked to the RRE structure. Moreover, Rev influenced the subcellular localization of NF90ctv, and this process is leptomycin B sensitive. Conclusion The dsRNA binding protein, NF90ctv competes with HIV Rev function at two levels, by competitive protein:protein interaction involving Rev binding to specific domains of NF90ctv, as well as by its binding to the RRE-RNA structure. Our results are consistent with a model of Rev-mediated HIV-1 RNA export that envisions Rev-multimerization, a process interrupted by NF90ctv.

    Mass vaccination with reduced dose 1/50 Rev 1 strain live vaccine (1-2 10(9) colony forming units), administered subcutaneously, over a four and a half year period reduced the prevalence of Brucella melitensis in Kuwait's small ruminant population from 5.8% in 1993 to 2.02% in 1997. Serological test results using the Rose Bengal Plate Test, Rivanol Agglutination Test and Complement Fixation showed no evidence of persistence of positive serology in animals nine or more months after vaccination. Questionnaires and post-vaccination flock inspections found that the effects on gestation (abortions) were minimal--and not proven to be due to the vaccine. The conclusion from these findings is that mass vaccination with reduced dose Rev 1 administered by the subcutaneous route is a practical field strategy for control of Brucella melitensis.

  2. Non-social adaptation defers a tragedy of the commons in Pseudomonas aeruginosa quorum sensing.

    In a process termed quorum sensing (QS), the opportunistic bacterial pathogen Pseudomonas aeruginosa uses diffusible signaling molecules to regulate the expression of numerous secreted factors or public goods that are shared within the population. But not all cells respond to QS signals. These social cheaters typically harbor a mutation in the QS receptor gene lasR and exploit the public goods produced by cooperators. Here we show that non-social adaptation under growth conditions that require QS-dependent public goods increases tolerance to cheating and defers a tragedy of the commons. The underlying mutation is in the transcriptional repressor gene psdR. This mutation has no effect on public goods expression but instead increases individual fitness by derepressing growth-limiting intracellular metabolism. Even though psdR mutant populations remain susceptible to invasion by isogenic psdR lasR cheaters, they bear a lower cheater load than do wild-type populations, and they are completely resistant to invasion by lasR cheaters with functional psdR. Mutations in psdR also sustain growth near wild-type levels when paired with certain partial loss-of-function lasR mutations. Targeted sequencing of multiple evolved isolates revealed that mutations in psdR arise before mutations in lasR, and rapidly sweep through the population. Our results indicate that a QS-favoring environment can lead to adaptations in non-social, intracellular traits that increase the fitness of cooperating individuals and thereby contribute to population-wide maintenance of QS and associated cooperative behaviors.

  3. Ion Beam Synthesis of Ge Nanowires. rev. ed.

    2001-01-01

    The formation of Ge nanowires in V-grooves has been studied experimentally as well as theoretically. As substrate oxide covered Si V-grooves were used formed by anisotropic etching of (001)Si wafers and subsequent oxidation of their surface. Implantation of 1 x 10{sup 17} Ge{sup +}cm{sup -2} at 70 keV was carried out into the oxide layer covering the V-grooves. Ion irradiation induces shape changes of the V-grooves, which are captured in a novel continuum model of surface evolution. It describes theoretically the effects of sputtering, redeposition of sputtered atoms, and swelling. Thereby, the time evolution of the target surface is determined by a nonlinear integro-differential equation, which was solved numerically for the V-groove geometry. A very good agreement is achieved for the predicted surface shape and the shape observed in XTEM images. Surprisingly, the model predicts material (Si, O, Ge) transport into the V-groove bottom which also suggests an Ge accumulation there proven by STEM-EDX investigations. In this Ge rich bottom region, subsequent annealing in N{sub 2} atmosphere results in the formation of a nanowire by coalescence of Ge precipitates shown by XTEM images. The process of phase separation during the nanowire growth was studied by means of kinetic 3D lattice Monte-Carlo simulations. These simulations also indicate the disintegration of continuous wires into droplets mediated by thermal fluctuations. Energy considerations have identified a fragmentation threshold and a lower boundary for the droplet radii which were confirmed by the Monte Carlo simulation. The here given results indicate the possibility of achieving nanowires being several nanometers wide by further growth optimizations as well as chains of equally spaced clusters with nearly uniform diameter.

    We present a reanalysis of the data from Stanford Linear Accelerator Center (SLAC) experiments E140 [R. C. Walker et al., Phys. Rev. D 49, 5671 (1994), 10.1103/PhysRevD.49.5671] and NE11 [L. Andivahis et al., Phys. Rev. D 50, 5491 (1994), 10.1103/PhysRevD.50.5491] on elastic electron-proton scattering. This work is motivated by recent progress in calculating the corresponding radiative corrections and by the apparent discrepancy between the Rosenbluth and polarization transfer measurements of the proton electromagnetic form factors. New, corrected values for the scattering cross sections are presented, as well as a new form factor fit in the Q2 range from 1 to 8.83 GeV2. We also provide a complete set of revised formulas to account for radiative corrections in single-arm measurements of unpolarized elastic electron-proton scattering.

    Purpose: To report the outcomes of repeat stereotactic radiosurgery (SRS), deferring whole-brain radiation therapy (WBRT), for distant intracranial recurrences and identify factors associated with prolonged overall survival (OS). Patients and Methods: We retrospectively identified 652 metastases in 95 patients treated with 2 or more courses of SRS for brain metastases, deferring WBRT. Cox regression analyzed factors predictive for OS. Results: Patients had a median of 2 metastases (range, 1-14) treated per course, with a median of 2 courses (range, 2-14) of SRS per patient. With a median follow-up after first SRS of 15 months (range, 3-98 months), the median OS from the time of the first and second course of SRS was 18 (95% confidence interval [CI] 15-24) and 11 months (95% CI 6-17), respectively. On multivariate analysis, histology, graded prognostic assessment score, aggregate tumor volume (but not number of metastases), and performance status correlated with OS. The 1-year cumulative incidence, with death as a competing risk, of local failure was 5% (95% CI 4-8%). Eighteen (24%) of 75 deaths were from neurologic causes. Nineteen patients (20%) eventually received WBRT. Adverse radiation events developed in 2% of SRS sites. Conclusion: Multiple courses of SRS, deferring WBRT, for distant brain metastases after initial SRS, seem to be a safe and effective approach. The graded prognostic assessment score, updated at each course, and aggregate tumor volume may help select patients in whom the deferral of WBRT might be most beneficial.

    Perform a cost-effectiveness analysis of the treatment of diabetic macular edema (DME) with ranibizumab plus prompt or deferred laser versus triamcinolone plus prompt laser. Data for the analysis were drawn from reports of the Diabetic Retinopathy Clinical Research Network (DRCRnet) Protocol I. Computer simulation based on Protocol I data. Analyses were conducted from the payor perspective. Simulated participants assigned characteristics reflecting those seen in Protocol I. Markov models were constructed to replicate Protocol I's 104-week outcomes using a microsimulation approach to estimation. Baseline characteristics, visual acuity (VA), treatments, and complications were based on Protocol I data. Costs were identified by literature search. One-way sensitivity analysis was performed, and the results were validated against Protocol I data. Direct cost of care for 2 years, change in VA from baseline, and incremental cost-effectiveness ratio (ICER) measured as cost per additional letter gained from baseline (Early Treatment of Diabetic Retinopathy Study). For sham plus laser (S+L), ranibizumab plus prompt laser (R+pL), ranibizumab plus deferred laser (R+dL), and triamcinolone plus laser (T+L), effectiveness through 104 weeks was predicted to be 3.46, 7.07, 8.63, and 2.40 letters correct, respectively. The ICER values in terms of dollars per VA letter were $393 (S+L vs. T+L), $5943 (R+pL vs. S+L), and $20 (R+dL vs. R+pL). For pseudophakics, the ICER value for comparison triamcinolone with laser versus ranibizumab with deferred laser was $14 690 per letter gained. No clinically relevant changes in model variables altered outcomes. Internal validation demonstrated good similarity to Protocol I treatment patterns. In treatment of phakic patients with DME, ranibizumab with deferred laser provided an additional 6 letters correct compared with triamcinolone with laser at an additional cost of $19 216 over 2 years. That would indicate that if the gain in VA seen at 2 years

    2017-01-01

    Full Text Available Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its engineering application. The key to the method is to determine a representative elementary volume (REV. The FractureToKarst software, that is, discrete element software, is a main analysis tool in this paper and developed by a number of authors. According to the standard of rock classification established by ISRM, this paper aims to discuss the existence and the size of REV of fractured rock masses with medium tractility and provide a general method to determine the existence of REV. It can be gleaned from the study that the existence condition of fractured rock mass with medium tractility features average fracture spacing smaller than 0.6 m. If average fracture spacing is larger than 0.6 m, there is no existence of REV. The rationality of the model is verified by a case study. The present research provides a method for the simulation of seepage field in fissured rocks.

  4. A comparison of high-order explicit Runge–Kutta, extrapolation, and deferred correction methods in serial and parallel

    KAUST Repository

    Ketcheson, David I.

    2014-06-13

    We compare the three main types of high-order one-step initial value solvers: extrapolation, spectral deferred correction, and embedded Runge–Kutta pairs. We consider orders four through twelve, including both serial and parallel implementations. We cast extrapolation and deferred correction methods as fixed-order Runge–Kutta methods, providing a natural framework for the comparison. The stability and accuracy properties of the methods are analyzed by theoretical measures, and these are compared with the results of numerical tests. In serial, the eighth-order pair of Prince and Dormand (DOP8) is most efficient. But other high-order methods can be more efficient than DOP8 when implemented in parallel. This is demonstrated by comparing a parallelized version of the wellknown ODEX code with the (serial) DOP853 code. For an N-body problem with N = 400, the experimental extrapolation code is as fast as the tuned Runge–Kutta pair at loose tolerances, and is up to two times as fast at tight tolerances.

  5. The evolution of prestige: freely conferred deference as a mechanism for enhancing the benefits of cultural transmission.

    Science.gov (United States)

    Henrich, J; Gil-White, F J.

    2001-05-01

    This paper advances an "information goods" theory that explains prestige processes as an emergent product of psychological adaptations that evolved to improve the quality of information acquired via cultural transmission. Natural selection favored social learners who could evaluate potential models and copy the most successful among them. In order to improve the fidelity and comprehensiveness of such ranked-biased copying, social learners further evolved dispositions to sycophantically ingratiate themselves with their chosen models, so as to gain close proximity to, and prolonged interaction with, these models. Once common, these dispositions created, at the group level, distributions of deference that new entrants may adaptively exploit to decide who to begin copying. This generated a preference for models who seem generally "popular." Building on social exchange theories, we argue that a wider range of phenomena associated with prestige processes can more plausibly be explained by this simple theory than by others, and we test its predictions with data from throughout the social sciences. In addition, we distinguish carefully between dominance (force or force threat) and prestige (freely conferred deference).

  6. Accounting choices in Brazil: identifying the characteristics of publicly traded companies that opted to maintain versus derecognise deferred assets

    Directory of Open Access Journals (Sweden)

    Fernando Drago Lorencini

    2012-04-01

    Full Text Available The issuance of Brazilian Law 11.638/2007 is a critical step in the convergence of the Brazilian Generally Accepted Accounting Principles (GAAPs towards International Financial Reporting Standards. After the law was implemented and later modified by Provisional Executive Order 449/2008 (converted into Law 11.941/2009, certain accounting choices were allowed during the transition period. The Brazilian GAAPs allowed for restructuring costs and costs related to opening a new facility to be recognised as assets. As a transitional provision, companies were allowed to choose between maintaining or eliminating these values. In this paper, we attempted to identify which company characteristics were associated with this accounting choice. The final sample consisted of Brazilian companies listed on the BM & FBOVESPA, and a logistic regression identified two characteristics. Participation in one of the three different corporate governance levels of the BM & FBOVESPA was associated with the choice to derecognise the deferred assets, while companies decided to maintain the deferred asset if it was relatively large. The empirical evidence reported here contributes to the literature by explaining the manner in which a set of firm characteristics is related to a firm's accounting choices.

  7. Hard bottom substrate monitoring Horns Rev offshore wind farm. Annual status report 2003

    Leonhard, S.B.; Pedersen, John

    2004-05-15

    Elsam and Eltra built the offshore demonstration wind farm at Horns Rev in the North Sea. Elsam is the owner and is responsible for the operation of the wind farm. Eltra is responsible for the connection of the wind farm to the national onshore grid. In the summer months of 2002, Elsam constructed the world's largest offshore wind farm off the Danish west coast. The wind farm is sited 14-20 km into the North Sea, west of Blaevands Huk. The first wind turbine was erected in May 2002 and the last wind turbine tower of a total of 80 was in place by August 2002. The construction work was completed with the last connecting cables sluiced down in September 2002. All the wind turbines were in production by December 2002. The expected impact of the wind farm will primarily be an alternation of habitats due to the introduction of hard bottom substrates as wind turbine towers and scour protections. A continuous development in the epifouling communities will be expected together with an introduction of new or alien species in the area. The indigenous benthic community in the area of Horns Rev can be characterised by infauna species belonging to the Goniadella-Spisula community. This community is typical of sandbanks in the North Sea area, although communities in such areas are very variable and site-specific. Character species used as indicators for environmental changes in the Horns Rev area are the bristle worms Goniadella bobretzkii, Ophelia borealis, Psione remota and Orbinia sertulata and the mussels Goodallia triangularis and Spisula solida. In connection with the implementation of the monitoring programme concerning the ecological impact of the introduction of hard substrate related to the Horns Rev Wind Farm, surveys on hard bottom substrate was conducted in March 2003 and in September 2003. This report describes the first year results of surveys on hard substrate after the completion of the offshore wind farm at Horns Rev. (au)

    2015-12-01

    Full Text Available Most information underlying the decision to invest at the level of a company, are provided by the accountancy, this becoming today a common language with respect to the businesses on the international markets, and the accountancy normalization was extrapolated from the national level to the international level, due to the needs concerning the comparability and the transparency of the entities financial statements, without considering the geopolitical area where they were built. These issues justify the approaches for improving both accounting treatments and the procedures for elaborating and presenting data within the financial statements such that the users to benefit from credible and transparent information. One of the major issues arising with respect to the performance of an entity aims to prepare a unique situation on the company performance, namely:“the statement of the comprehensive income”, having as primordial objective the facility of forecasting the performance, within which the deferred taxes generated by the subventions for investments are an essential element with an important predictive value. In this context, starting from the main differences between the provisions of the national, Anglo-Saxon accounting regulations and those of the international reference system with respect to the predictive value of the deferred taxes and continuing with the occurrence and evolution of the deferred taxes generated by the subventions for investments, the study proposes to highlight the predictive value of the deferred taxes generated by the subventions for investments, provided o the users by the information of annual financial statements.

  16. Deferred imitation in 18-month-olds from two cultural contexts: the case of Cameroonian Nso farmer and German-middle class infants.

    2013-12-01

    Imitative learning has been described in naturalistic studies for different cultures, but lab-based research studying imitative learning across different cultural contexts is almost missing. Therefore, imitative learning was assessed with 18-month-old German middle-class and Cameroonian Nso farmer infants - representing two highly different eco-cultural contexts associated with different cultural models, the psychological autonomy and the hierarchical relatedness - by using the deferred imitation paradigm. Study 1 revealed that the infants from both cultural contexts performed a higher number of target actions in the deferred imitation than in the baseline phase. Moreover, it was found that German middle-class infants showed a higher mean imitation rate as they performed more target actions in the deferred imitation phase compared with Cameroonian Nso farmer infants. It was speculated that the opportunity to manipulate the test objects directly after the demonstration of the target actions could enhance the mean deferred imitation rate of the Cameroonian Nso farmer infants which was confirmed in Study 2. Possible explanations for the differences in the amount of imitated target actions of German middle-class and Cameroonian Nso farmer infants are discussed considering the object-related, dyadic setting of the imitation paradigm with respect to the different learning contexts underlying the different cultural models of learning.

  18. Identification of Brucella melitensis Rev.1 vaccine-strain genetic markers: Towards understanding the molecular mechanism behind virulence attenuation.

    Science.gov (United States)

    Issa, Mohammad Nouh; Ashhab, Yaqoub

    2016-09-22

    Brucella melitensis Rev.1 is an avirulent strain that is widely used as a live vaccine to control brucellosis in small ruminants. Although an assembled draft version of Rev.1 genome has been available since 2009, this genome has not been investigated to characterize this important vaccine. In the present work, we used the draft genome of Rev.1 to perform a thorough genomic comparison and sequence analysis to identify and characterize the panel of its unique genetic markers. The draft genome of Rev.1 was compared with genome sequences of 36 different Brucella melitensis strains from the Brucella project of the Broad Institute of MIT and Harvard. The comparative analyses revealed 32 genetic alterations (30 SNPs, 1 single-bp insertion and 1 single-bp deletion) that are exclusively present in the Rev.1 genome. In silico analyses showed that 9 out of the 17 non-synonymous mutations are deleterious. Three ABC transporters are among the disrupted genes that can be linked to virulence attenuation. Out of the 32 mutations, 11 Rev.1 specific markers were selected to test their potential to discriminate Rev.1 using a bi-directional allele-specific PCR assay. Six markers were able to distinguish between Rev.1 and a set of control strains. We succeeded in identifying a panel of 32 genome-specific markers of the B. melitensis Rev.1 vaccine strain. Extensive in silico analysis showed that a considerable number of these mutations could severely affect the function of the associated genes. In addition, some of the discovered markers were able to discriminate Rev.1 strain from a group of control strains using practical PCR tests that can be applied in resource-limited settings.

    2004-06-10

    Vaccination of young animals (3-6-month-old sheep and goats) with Rev-1 vaccine for 15 years in Greece, importantly decreased the abortions in sheep and goats as well as the incidence of brucellosis in humans. After the stop of vaccination in 1994, all over Greece, the prevalence of brucellosis in animals and the incidence in humans quickly increased. It was a positive rank correlation (0.90) among these variables. Once an emergency mass-vaccination programme of young and adult animals with Rev-1 vaccine was started in 1998, the human incidence again decreased. The association of the vaccination coverage of animals and incidence of brucellosis in humans was not linear; the decrease in human brucellosis incidence was observed when the vaccination coverage of animals was >30%.

    The simple fact that proteins are built from 20 amino acids while DNA only contains four different bases, means that the 'signal-to-noise ratio' in protein sequence alignments is much better than in alignments of DNA. Besides this information-theoretical advantage, protein alignments also benefit...... proteins. It is therefore preferable to align coding DNA at the amino acid level and it is for this purpose we have constructed the program RevTrans. RevTrans constructs a multiple DNA alignment by: (i) translating the DNA; (ii) aligning the resulting peptide sequences; and (iii) building a multiple DNA...... alignment by 'reverse translation' of the aligned protein sequences. In the resulting DNA alignment, gaps occur in groups of three corresponding to entire codons, and analogous codon positions are therefore always lined up. These features are useful when constructing multiple DNA alignments for phylogenetic...

    Elsam and Eltra have built the offshore demonstration wind farm at Horns Rev in the North Sea. Elsam is the owner and is responsible for the operation of the wind farm. Eltra is responsible for the connection of the wind farm to the national onshore grid. In the summer months of 2002, Elsam constructed the world's largest offshore wind farm at the Danish west coast. The wind farm is located 14-20 km into the North Sea, west of Blaevands Huk. The first wind turbine foundation was in place in March 2002 and the last mono-pile was in place in August 2002 for a total of 80. The construction work was completed with the last connecting cables sluiced down in September 2002. All the wind turbines were in production in December 2002. The expected impact from the wind farm will primarily be an alternation of habitats due to the introduction of hard bottom substrates as wind mono-piles and scour protections. A continuous development in the epifouling communities will be expected together with an introduction of new or alien species in the area. The indigenous benthic community in the area of Horn Rev can be characterised by infauna species belonging to the Goniadella-Spisula community. This community is typical of sandbanks in the North Sea area, although communities in such areas are very variable and site specific. Character species used as indicators for environmental changes in the Horns Rev area are the bristle worms Goniadella bobretzkii, Ophelia borealis, Psione remota and Orbinia sertulata and the mussels Goodallia triangularis and Spisula solida. In connection with the implementation of the monitoring programme concerning the ecological impact of the introduction of hard substrate related to the Horns Rev Wind Farm, surveys on hard bottom substrates were initialised in March 2003 with monitoring conducted in September 2003 and March and September 2004. This report describes the results from surveys on hard substrates in 2004. (au)

    While clinicians and HIV/AIDS patients anxiously watch the trend of the virus developing resistance to multiple antiretroviral therapies, the question remains whether new drug research will continue to save the day. Some suggest there will need to be multiple new classes of antiretroviral drugs developed in order to stretch further the life span of longtime HIV patients. One potential new class would target the Rev protein, an approach that has received very little attention from the research and pharmaceutical communities.

    Full Text Available Clerical masculinities, much like their lay/secular counterparts, often appear unchang¬ing because they are the products of naturalization processes. Clerical masculinities, however, are far from stable, for they live and breathe the dynamics of both their socio-religious context and their secular “others”. The BBC sitcom Rev. (BBC2, UK 2010–2014 is a refreshing take on the everyday life and problems of a vicar in the Church of England trying to avoid stereotypes that often come with clerical roles. Rev. (2010–2014 can be interpreted as an attempt to explore the negotiation processes of masculinity within an institution that is involved in the “production” of religion and gender roles. It shows that being a man in an institutional setting is as much a perfor¬mance as it is a more or less successful negotiation of other people’s expectations and one’s own worldview. In particular, the main male clerical characters in Rev. (2010– 2014 inhabit a position of power but all have their flaws. They can best be understood as losers whose clash with masculine systems renders them more human.

    Evaluate intravitreal 0.5 mg ranibizumab or 4 mg triamcinolone combined with focal/grid laser compared with focal/grid laser alone for treatment of diabetic macular edema (DME). Multicenter, randomized clinical trial. A total of 854 study eyes of 691 participants with visual acuity (approximate Snellen equivalent) of 20/32 to 20/320 and DME involving the fovea. Eyes were randomized to sham injection + prompt laser (n=293), 0.5 mg ranibizumab + prompt laser (n=187), 0.5 mg ranibizumab + deferred (> or =24 weeks) laser (n=188), or 4 mg triamcinolone + prompt laser (n=186). Retreatment followed an algorithm facilitated by a web-based, real-time data-entry system. Best-corrected visual acuity and safety at 1 year. The 1-year mean change (+/-standard deviation) in the visual acuity letter score from baseline was significantly greater in the ranibizumab + prompt laser group (+9+/-11, Peyes at baseline (n=273), visual acuity improvement in the triamcinolone + prompt laser group appeared comparable to that in the ranibizumab groups. No systemic events attributable to study treatment were apparent. Three eyes (0.8%) had injection-related endophthalmitis in the ranibizumab groups, whereas elevated intraocular pressure and cataract surgery were more frequent in the triamcinolone + prompt laser group. Two-year visual acuity outcomes were similar to 1-year outcomes. Intravitreal ranibizumab with prompt or deferred laser is more effective through at least 1 year compared with prompt laser alone for the treatment of DME involving the central macula. Ranibizumab as applied in this study, although uncommonly associated with endophthalmitis, should be considered for patients with DME and characteristics similar to those in this clinical trial. In pseudophakic eyes, intravitreal triamcinolone + prompt laser seems more effective than laser alone but frequently increases the risk of intraocular pressure elevation.

    2011-07-01

    Full Text Available Abstract Background Central to the fully competent replication cycle of the human immunodeficiency virus type 1 (HIV-1 is the nuclear export of unspliced and partially spliced RNAs mediated by the Rev posttranscriptional activator and the Rev response element (RRE. Results Here, we introduce a novel method to explore the proteome associated with the nuclear HIV-1 RNAs. At the core of the method is the generation of cell lines harboring an integrated provirus carrying RNA binding sites for the MS2 bacteriophage protein. Flag-tagged MS2 is then used for affinity purification of the viral RNA. By this approach we found that the viral RNA is associated with the host nuclear matrix component MATR3 (Matrin 3 and that its modulation affected Rev activity. Knockdown of MATR3 suppressed Rev/RRE function in the export of unspliced HIV-1 RNAs. However, MATR3 was able to associate with Rev only through the presence of RRE-containing viral RNA. Conclusions In this work, we exploited a novel proteomic method to identify MATR3 as a cellular cofactor of Rev activity. MATR3 binds viral RNA and is required for the Rev/RRE mediated nuclear export of unspliced HIV-1 RNAs.

    The present report presents the results of three bird surveys conducted in the Horns Rev area during the second half of 2001. Due to poor weather conditions in December 2001, the last survey was, however, performed on 7 January 2002. The surveys are part of the base-line investigations of birds performed in relation to the proposed construction of an offshore wind farm at Horns Rev in the Danish part of the North Sea ca 14 km southwest of Blaevandshuk. The results of the surveys during August 2001 - January 2002 are presented together with the results obtained during the period August 2000 - April 2001, and are also compared to results obtained during the period August 1999 - April 2000. Based on the distribution of the most abundant bird species recorded during 16 aerial surveys performed during August 1999 - January 2002, there were no indications that the wind farm area was of any particular importance to the birds' exploitation of the Horns Rev area. Fish-eating species like divers, gannet, terns, auks and gulls generally showed scattered and variable distributions, mainly occurring in the areas north and south of Horns Rev, and with low numbers on the reef proper and within the planned wind farm area. The distribution of benthic foraging species, eider and common Scoter, showed that they mainly exploited the coastal parts of the area off Blaevandshuk and Skallingen, although common scoter was found in relatively high numbers on the southeast slopes of the Horns Rev and within the wind farm area in the April 2001 survey. Common scoters occurred in very high numbers in January 2002. This was probably related to increased immigration of birds from the inner Danish waters during a cold period in late December 2001. Preference analyses of bird exploitation of the Horns Rev area showed that if the birds completely avoid the wind farm area after erection of the wind turbines, this will affect less than 1% of the various species, except divers where 1.58% will be

  20. Xpf and not the Fanconi anaemia proteins or Rev3 accounts for the extreme resistance to cisplatin in Dictyostelium discoideum.

    Directory of Open Access Journals (Sweden)

    Xiao-Yin Zhang

    2009-09-01

    Full Text Available Organisms like Dictyostelium discoideum, often referred to as DNA damage "extremophiles", can survive exposure to extremely high doses of radiation and DNA crosslinking agents. These agents form highly toxic DNA crosslinks that cause extensive DNA damage. However, little is known about how Dictyostelium and the other "extremophiles" can tolerate and repair such large numbers of DNA crosslinks. Here we describe a comprehensive genetic analysis of crosslink repair in Dictyostelium discoideum. We analyse three gene groups that are crucial for a replication-coupled repair process that removes DNA crosslinks in higher eukarya: The Fanconi anaemia pathway (FA, translesion synthesis (TLS, and nucleotide excision repair. Gene disruption studies unexpectedly reveal that the FA genes and the TLS enzyme Rev3 play minor roles in tolerance to crosslinks in Dictyostelium. However, disruption of the Xpf nuclease subcomponent results in striking hypersensitivity to crosslinks. Genetic interaction studies reveal that although Xpf functions with FA and TLS gene products, most Xpf mediated repair is independent of these two gene groups. These results suggest that Dictyostelium utilises a distinct Xpf nuclease-mediated repair process to remove crosslinked DNA. Other DNA damage-resistant organisms and chemoresistant cancer cells might adopt a similar strategy to develop resistance to DNA crosslinking agents.

    To characterize HIV-1 specific CTL responses to regulatory proteins Tat and Rev in HIV-B'/C vires-infected ART-naive individuals. Methods HIV-1-specific CTL responses were analyzed by IFN-γ ELISPOT assay using overlapping peptides spanning the consensus sequences of HIV-1 clade C Tat and Rev proteins. Statistical analysis and graphical presentation were performed using SIGMAPLOT 10.0 and SIGMASTAT 3.5. For samples with a positive response, the magnitude of CTL responses was compared between HIV-1 C proteins by Wilcoxon rank sum test, and the significance threshold was P<0.05. Results Tat and Rev were frequently recognized, with 23% and 52% of the tested individuals having detectable responses to these proteins, respectively. Several immunodominant regions were detected in Rev. No significant correlation was observed between the magnitude and breadth of CTL responses to regulatory proteins and the control of virus replication in this study. Conclusion Tat and Rev can serve as targets for HIV-1-specific CTL, and several immunodominant regions are detectable in Rev. Further characterization of epitopes and their role in virus control may shed light on pathogenesis of HIV-1 natural infection and also be useful for the design and testing of candidate vaccines.

  6. HIV-1 Rev protein specifies the viral RNA export pathway by suppressing TAP/NXF1 recruitment.

    2014-06-01

    Nuclear RNA export pathways in eukaryotes are often linked to the fate of a given RNA. Therefore, the choice of export pathway should be well-controlled to avoid an unfavorable effect on gene expression. Although some RNAs could be exported by more than one pathway, little is known about how the choice is regulated. This issue is highlighted when the human immunodeficiency virus type 1 (HIV-1) Rev protein induces the export of singly spliced and unspliced HIV-1 transcripts. How these RNAs are exported is not well understood because such transcripts should have the possibility of utilizing CRM1-dependent export via Rev or cellular TAP/NXF1-dependent export via the transcription/export (TREX) complex, or both. Here we found that Rev suppressed TAP/NXF1-dependent export of model RNA substrates that recapitulated viral transcripts. In this effect, Rev interacted with the cap-binding complex and inhibited the recruitment of the TREX complex. Thus, Rev controls the identity of the factor occupying the cap-proximal region that determines the RNA export pathway. This ribonucleoprotein remodeling activity of Rev may favor viral gene expression.

    Full Text Available Los sistemas pecuarios de las áreas subtropicales de la Argentina utilizan en invierno forrajes diferidos, provenientes del crecimiento acumulado en verano de gramíneas megatérmicas o pasturas naturales. El objetivo del trabajo fue determinar la producción de materia seca, porcentajes de hojas, tallos, proteína bruta, fibra detergente neutra, fibra detergente ácida, cenizas y digestibilidad del diferido de Panicum coloratum cv Verde. Se evaluaron dos periodos de diferimiento: diferido total (DT, forraje acumulado desde el rebrote en primavera y diferido parcial (DP, forraje acumulado desde un corte a fines de diciembre y ambos con tres oportunidades de defoliación: temprano (mayo; intermedio (julio y tardío (agosto. DT produjo más materia seca, pero con alta proporción de tallos, mayor cantidad de fibra y menor porcentaje de proteínas y cenizas; mientras que DP presentó menos tallos y más hojas y como consecuencia mayor porcentaje de proteínas y cenizas. Se concluye que P. coloratum es un recurso adecuado para diferir, sólo si se lo utiliza con un período corto de diferido y momentos tempranos de uso, ya que presenta un nivel mínimo de proteína suficiente para satisfacer los requerimientos de los animales sin la necesidad de realizar suplementación nitrogenada y valores superiores al 55% de digestibilidad.During winter the livestock production systems in subtropical areas of Argentina use deferred forage of native pasture or warm season grasses from the cumulative growth of the summer.

    The complete genome of Marek's disease virus (MDV) strain GX0101,which was integrated with the LTR sequences of REV,was cloned in Escherichia coli as a bacterial artificial chromosome (BAC).BAC vector sequences were introduced into the US2 locus of the MDV genome by homologous recombination.The viral DNA containing the BAC vector was used to transform Escherichia coli strain of DH10B.Then the recombinant virus was successfully rescued by transfection of the recombinant BAC DNA into primary chicken embryo fibroblast (CEF).This BAC viral clone was named bac-GX0101.When the reconstituted virus was inoculated into 1-day-old birds,visceral tumors could be detected as early as 62 d post infection.There was no difference in growth ability and pathogenicity to birds between the BAC derived virus and its parental virus.The BAC derived virus maintained its oncogenicity and immunosuppressive effects.In conclusion,the complete genome of GX0101 strain was successfully cloned into BAC and the infectious clone was rescued.With the powerful BAC manipulation system,the infectious clone will provide a useful tool for further understanding the functional roles of the inserted REV-LTR sequence in the GX0101 strain of MDV.

  14. High amplitude phase resetting in rev-erbalpha/per1 double mutant mice.

    Directory of Open Access Journals (Sweden)

    Corinne Jud

    Full Text Available Over time, organisms developed various strategies to adapt to their environment. Circadian clocks are thought to have evolved to adjust to the predictable rhythms of the light-dark cycle caused by the rotation of the Earth around its own axis. The rhythms these clocks generate persist even in the absence of environmental cues with a period of about 24 hours. To tick in time, they continuously synchronize themselves to the prevailing photoperiod by appropriate phase shifts. In this study, we disrupted two molecular components of the mammalian circadian oscillator, Rev-Erbalpha and Period1 (Per1. We found that mice lacking these genes displayed robust circadian rhythms with significantly shorter periods under constant darkness conditions. Strikingly, they showed high amplitude resetting in response to a brief light pulse at the end of their subjective night phase, which is rare in mammals. Surprisingly, Cry1, a clock component not inducible by light in mammals, became slightly inducible in these mice. Taken together, Rev-Erbalpha and Per1 may be part of a mechanism preventing drastic phase shifts in mammals.

  15. Is selective attention the basis for selective imitation in infants? An eye-tracking study of deferred imitation with 12-month-olds.

    Infants and children do not blindly copy every action they observe during imitation tasks. Research demonstrated that infants are efficient selective imitators. The impact of selective perceptual processes (selective attention) for selective deferred imitation, however, is still poorly described. The current study, therefore, analyzed 12-month-old infants' looking behavior during demonstration of two types of target actions: arbitrary versus functional actions. A fully automated remote eye tracker was used to assess infants' looking behavior during action demonstration. After a 30-min delay, infants' deferred imitation performance was assessed. Next to replicating a memory effect, results demonstrate that infants do imitate significantly more functional actions than arbitrary actions (functionality effect). Eye-tracking data show that whereas infants do not fixate significantly longer on functional actions than on arbitrary actions, amount of fixations and amount of saccades differ between functional and arbitrary actions, indicating different encoding mechanisms. In addition, item-level findings differ from overall findings, indicating that perceptual and conceptual item features influence looking behavior. Looking behavior on both the overall and item levels, however, does not relate to deferred imitation performance. Taken together, the findings demonstrate that, on the one hand, selective imitation is not explainable merely by selective attention processes. On the other hand, notwithstanding this reasoning, attention processes on the item level are important for encoding processes during target action demonstration. Limitations and future studies are discussed.

    Summary Background The optimum time to start antiretroviral therapy for children diagnosed with HIV infection after 1 year of age is unknown. We assessed whether antiretroviral therapy could be deferred until CD4 percentages declined to less than 15% without affecting AIDS-free survival. Methods In our multicentre, randomised, open-label trial at nine research sites in Thailand and Cambodia, we enrolled children aged 1–12 years who were infected with HIV and had CD4 percentages of 15–24%. Participants were randomly assigned (1:1) by a minimisation scheme to start antiretroviral therapy at study entry (early treatment group) or antiretroviral therapy to start when CD4 percentages declined to less than 15% (deferred treatment group). The primary endpoint was AIDS-free survival (based on US Centers for Disease Control and Prevention category C events) at week 144, assessed with the Kaplan-Meier analysis and the log-rank approach. This study is registered with ClinicalTrials.gov, number NCT00234091. Findings Between March 28, 2006, and Sept 10, 2008, we enrolled 300 Thai and Cambodian children infected with HIV, with a median age of 6·4 years (IQR 3·9–8·4). 150 children were randomly allocated early antiretroviral therapy (one participant was excluded from analyses after withdrawing before week 0) and 150 children were randomly allocated deferred antiretroviral therapy. Median baseline CD4 percentage was 19% (16–22%). 69 children (46%) in the deferred treatment group started antiretroviral therapy during the study. AIDS-free survival at week 144 in the deferred treatment group was 98·7% (95% CI 94·7–99·7; 148 of 150 patients) compared with 97·9% (93·7–99·3; 146 of 149 patients) in the early treatment group (p=0·6). Interpretation AIDS-free survival in both treatment groups was high. This low event rate meant that our study was underpowered to detect differences between treatment start times and thus additional follow-up of study participants or

  17. Matrin 3 is a co-factor for HIV-1 Rev in regulating post-transcriptional viral gene expression

    Directory of Open Access Journals (Sweden)

    2011-07-01

    Full Text Available Abstract Post-transcriptional regulation of HIV-1 gene expression is mediated by interactions between viral transcripts and viral/cellular proteins. For HIV-1, post-transcriptional nuclear control allows for the export of intron-containing RNAs which are normally retained in the nucleus. Specific signals on the viral RNAs, such as instability sequences (INS and Rev responsive element (RRE, are binding sites for viral and cellular factors that serve to regulate RNA-export. The HIV-1 encoded viral Rev protein binds to the RRE found on unspliced and incompletely spliced viral RNAs. Binding by Rev directs the export of these RNAs from the nucleus to the cytoplasm. Previously, Rev co-factors have been found to include cellular factors such as CRM1, DDX3, PIMT and others. In this work, the nuclear matrix protein Matrin 3 is shown to bind Rev/RRE-containing viral RNA. This binding interaction stabilizes unspliced and partially spliced HIV-1 transcripts leading to increased cytoplasmic expression of these viral RNAs.

    Based on the published Avian reticuloendotheliosis virus (REV) whole genome sequence, primers and TaqMan probes were designed and synthesized, and the TaqMan probe fluorescence real-time quantitative RT-PCR (qRT-PCR) method for detecting the REV pol gene was established by optimizing the reaction conditions. Sensitivity analysis showed that the qRT-PCR method had a sensitivity that was 1,000-fold higher than conventional PCR. Additionally, no amplification signals were obtained when we attempted to detect DNA or cDNA of ALV-A/B/J, MDV, CIAV, IBDV, ARV, NDV, AIV, or other viruses, suggesting a high specificity for our method. Various titers of REV were artificially "spiked" into the FPV and MDV vaccines to simulate REV contamination in attenuated vaccines to validate this qRT-PCR method. Our findings indicated that this qRT-PCR method could detect REV contamination at a dose of 1 TCID50/1,000 feathers, which was 10,000-fold more sensitive than the regular RT-PCR detection (10(4) TCID50/1000 feathers).

    We show that a recent claim (H.Haberzettl, Phys. Rev. Lett. 85 (2000) 3576) that one cannot extract the nucleon weak axial form factor G_A (t) from charged pion threshold electroproduction is incorrect. Thus previous calculations remain valid and threshold charged pion electroproduction experiments can indeed be used to determine G_A (t), and they should certainly be pursued.

    Ignition experiments on the National Ignition Facility will use an indirectly driven spherical implosion to assemble and ignite a mass of DT fuel. Requirements describing the specifics of the experiment and the corresponding expected performance were established several years prior. These requirements include laser features, target fabrication and characterization, and data obtained from pre-ignition experiments. Since those requirements were originally set, various NIF experiments using surrogate targets have motivated updates to the target designs and requirements. A summary of these updates will be presented. Rev6 designs for CH(Si), C(W), and Be(Cu) will be summarized. One particularly significant change regards the thickness of the tent films supporting the capsule, and the presentation will include updated thickness goals and the experimental motivation for the change.

  6. Bayesian Assessment of Accuracy Properties of Rose Bengal Test in REV-1 Vaccinated Small Ruminants

    2015-12-01

    Full Text Available The live Brucella melitensis Rev-1 strain is considered the best vaccine available for the prevention of brucellosis in small ruminants. In Albania, vaccination of small ruminants with REV-1 has been used under various regimes since 2004. The effectiveness of the vaccination campaigns is monitored through a post vaccination monitoring and surveillance system based on testing vaccinated animals with Rose Bengal Plate Test (RBPT. Regrettably the test accuracy properties such as the sensitivity and specificity have not been validated in vaccinated small ruminants. The lack of knowledge on these properties hampers the correct evaluation of the true sero-conversion rate of the post vaccination monitoring at national and at flock scale. This study addressed this issue by using a Bayesian modelling framework to estimate two serological tests the RBPT which is the standard serological test used in the post vaccination monitoring and Complement Fixation Test (CFT. Serum samples from 191 reportedly vaccinated small ruminants were tested in parallel with RBPT and CFT. The estimates of sensitivity and specificity values of RBPT were 91% (95% CrI: 82 -98 and 89% (95% CrI: 70 - 98. For CFT the sensitivity resulted 86% (95% CrI: 70 - 95 and the specificity 95% (95% CrI: 80 - 99. The good sensitivity and acceptable specificity of RBPT support its utilization as screening test for post vaccination monitoring. The interpretation of the post vaccination data with RBPT are well acceptable at national level but not well suited for flock status interpretation. In terms of disease diagnosis, especially for a latter phase of the brucellosis control strategy in Albania, both tests could justify their use in association.

    Translesion synthesis (TLS) is a DNA damage tolerance mechanism in which DNA lesions are bypassed by specific polymerases. To investigate the role of TLS activities in ultraviolet light-induced somatic mutations, we analyzed Arabidopsis (Arabidopsis thaliana) disruptants of AtREV3, AtREV1, and/or AtPOLH genes that encode TLS-type polymerases. The mutation frequency in rev3-1 or rev1-1 mutants decreased compared with that in the wild type, suggesting that AtPolζ and AtRev1 perform mutagenic bypass events, whereas the mutation frequency in the polh-1 mutant increased, suggesting that AtPolη performs nonmutagenic bypass events with respect to ultraviolet light-induced lesions. The rev3-1 rev1-1 double mutant showed almost the same mutation frequency as the rev1-1 single mutant. The increased mutation frequency found in polh-1 was completely suppressed in the rev3-1 polh-1 double mutant, indicating that AtPolζ is responsible for the increased mutations found in polh-1. In summary, these results suggest that AtPolζ and AtRev1 are involved in the same (error-prone) TLS pathway that is independent from the other (error-free) TLS pathway mediated by AtPolη.

    The protection conferred by the reduced-dose Rev 1 Brucella melitensis vaccine in goats that had been immunized 5 years previously was evaluated. Sixteen goats vaccinated 5 years before with Rev 1 (1 x 10(5) cfu) and 5 non-vaccinated goats were challenged with B. melitensis 16M (4 x 10(5) cfu) using the conjunctival route. After giving birth or aborting, the goats were sacrificed and tissue samples were taken for bacteriological study. The challenge strain was recovered in 12%, of the animals from the vaccinated group, and in (80% of the control group. It is concluded, therefore that the use of reduced-dose Rev 1 protects goats vaccinated in endemic areas for at least 5 years after immunization.

    The interaction of the human immunodeficiency virus type 1 (HIV-1) regulatory protein Rev with cellular cofactors is crucial for the viral life cycle. The HIV-1 Rev transactivation domain is functionally interchangeable with analog regions of Rev proteins of other retroviruses suggesting common folding patterns. In order to obtain experimental evidence for similar structural features mediating protein-protein contacts we investigated activation domain peptides from HIV-1, HIV-2, VISNA virus, feline immunodeficiency virus (FIV) and equine infectious anemia virus (EIAV) by CD spectroscopy, secondary structure prediction and sequence analysis. Although different in polarity and hydrophobicity, all peptides showed a similar behavior with respect to solution conformation, concentration dependence and variations in ionic strength and pH. Temperature studies revealed an unusual induction of β-structure with rising temperatures in all activation domain peptides. The high stability of β-structure in this region was demonstrated in three different peptides of the activation domain of HIV-1 Rev in solutions containing 40% hexafluoropropanol, a reagent usually known to induce α-helix into amino acid sequences. Sequence alignments revealed similarities between the polar effector domains from FIV and EIAV and the leucine rich (hydrophobic) effector domains found in HIV-1, HIV-2 and VISNA. Studies on activation domain peptides of two dominant negative HIV-1 Rev mutants, M10 and M32, pointed towards different reasons for the biological behavior. Whereas the peptide containing the M10 mutation (L 78E 79→D 78L 79) showed wild-type structure, the M32 mutant peptide (L 78L 81L 83→A 78A 81A 83) revealed a different protein fold to be the reason for the disturbed binding to cellular cofactors. From our data, we conclude, that the activation domain of Rev proteins from different viral origins adopt a similar fold and that a β-structural element is involved in binding to a

  14. Comments on Phys. Rev. D89 (2014) 097101 "Reevaluation of the parton distribution of strange quarks in the nucleon"

    2014-01-01

    The HERMES collaboration in Phys. Rev. D89 (2014) 097101 extracted information about the strange quark density in the nucleon. One of the main results is an observation that the shape of the extracted density is very different from the shapes of the strange quark density from global QCD fits and also from that of the light antiquarks. In this paper systematic studies on the HERMES published multiplicity of pion and kaon data are presented. It is shown that the conclusions concerning the strange quark distribution in the nucleon reached in Phys. Rev. D89 (2014) 097101 are at the moment premature.

    The HIV Rev protein mediates the transport of partially and unspliced HIV mRNA from the nucleus to the cytoplasm. Rev multimerizes on a secondary stem-loop structure present in the viral intron-containing mRNA species and recruits the cellular karyopherin CRM1 to export viral mRNAs from the nucleus to the cytoplasm. Previously we have identified a single-domain intrabody (Nb(190)), derived from a llama heavy-chain antibody, which efficiently inhibits Rev multimerization and suppresses the production of infectious virus. We recently mapped the epitope of this nanobody and demonstrated that Rev residues K20 and Y23 are crucial for interaction while residues V16, H53 and L60 are important to a lesser extent. Here, we generated cell lines stably expressing Nb(190) and assessed the capacity of these cell lines to suppress the replication of different HIV-1 subtypes. These cells stably expressing the single-domain antibody are protected from virus-induced cytopathogenic effect even in the context of high multiplicity of infection. In addition, the replication of different subtypes of group M and one strain of group O is significantly suppressed in these cell lines. Next, we analysed the natural variations of Rev amino acids in sequence samples from HIV-1 infected patients worldwide and assessed the effect of Nb(190) on the most prevalent polymorphisms occurring at the key epitope positions (K20 and Y23) in Rev. We found that Nb(190) was able to suppress the function of these Rev variants except for the K20N mutant, which was present in only 0.7% of HIV-1 sequence populations (n = 4632). Cells stably expressing the single-domain intrabody Nb(190) are protected against virus-induced cytopathogenic effect and display a selective survival advantage upon infection. In addition, Nb(190) suppresses the replication of a wide range of different HIV-1 subtypes. Large-scale sequence analysis reveals that the Nb(190) epitope positions in Rev are well conserved across major HIV-1

    ELSAM and ELTRA have established an offshore wind farm with an output of 160 MW in the waters of Horns Rev 1420 km off Blaevands Huk, which is the most westerly point of Denmark. The first phase of construction of the wind farm started in spring 2002. Before the construction activities took place, a baseline description of the benthos was conducted as a part of an environmental monitoring programme for the establishment of the Horns Rev Offshore Wind Farm. The baseline surveys for the present monitoring programme were conducted in the wind farm area on three occasions: spring 1999, spring 2001 and September 2001. In designated reference areas, surveys were conducted in spring 1999 and September 2001. The reference areas in 1999 and September 2001 were placed at two different geographical locations because the survey in September 2001 was planned to be a part of a fish monitoring programme. A comparison between the baseline study in spring 2001 and the baseline study in autumn 2001 clearly revealed that the biomass of most species increased considerably from spring to September. Despite the increase in biomass, the overall distribution of the species and their relative abundance did not change. In order to use the baseline data to investigate a possible impact after the construction of the wind farm, it was essential to arrange the monitoring programme either in spring or in September 2003, because the baseline studies were conducted in these periods. The monitoring programme was conducted in September 2003 after the wind farm had become operational, parallel with the survey on hard bottom substrates. The impacts of the wind farm on the benthic fauna (infauna) in the area were mainly expected to be due to the alteration of the local currents. As the changes in the currents are only minor, impacts on the water chemistry and on the benthic fauna resulting from hydrodynamic causes were expected to be limited or non-existent. The main objective of the present monitoring

    A total of 40 species were identified from the surveys in the Horns Rev area in September 2004 while 42 species were identified in 2003 and 47 species in September 2001. The decline in the number of species occurred both inside the wind farm and reference areas, which indicates that the decline could be a combination of changes in sediment characteristics and natural variation rather than an effect from the establishment of the wind farm. More species were not associated with the hard substrate at the turbine sites in 2004 compared to 2003, while in 2001, more species were associated with fine-grained sand. The median sediment grain size increased from 2001 to 2003 to 2004, which suggests that the velocity of the current increased, but modelling calculations on current speed predicted a 2% reduction in the wind farm area and up to a 15% reduction very close to the scour protection. These results agreed with the grain sizes found at the stations 5, 25 and 100 metres from the scour protection. At most stations, the medium grain size was 5 metres lower from the scour protection compared with the station 100 metres from the scour protection, which indicates that the velocity of the current was lower close to the scour protection. No significant impact on the infauna in the wind farm area was detectable concerning distance-related effects. Though general reductions in the population size of some of the character species in the surveyed areas might be related to changes in the sediment structure, the infauna community at Horns Rev showed no obvious sign of stress response as a consequence of possible impact from construction and operating activities. New species were observed in 2003 and 2004 and some of these might be a result of sediment characteristics, less predation or natural variation. The recording of other species might be a result of the introduction of hard bottom habitants in the wind farm area. The density of the most abundant bivalves and bristle worms was

    Full Text Available Abstract Background The Sydney blood bank cohort (SBBC of long-term survivors consists of multiple individuals infected with nef-deleted, attenuated strains of human immunodeficiency virus type 1 (HIV-1. Although the cohort members have experienced differing clinical courses and now comprise slow progressors (SP as well as long-term nonprogressors (LTNP, longitudinal analysis of nef/long-terminal repeat (LTR sequences demonstrated convergent nef/LTR sequence evolution in SBBC SP and LTNP. Thus, the in vivo pathogenicity of attenuated HIV-1 strains harboured by SBBC members is dictated by factors other than nef/LTR. Therefore, to determine whether defects in other viral genes contribute to attenuation of these HIV-1 strains, we characterized dominant HIV-1 rev alleles that persisted in 4 SBBC subjects; C18, C64, C98 and D36. Results The ability of Rev derived from D36 and C64 to bind the Rev responsive element (RRE in RNA binding assays was reduced by approximately 90% compared to Rev derived from HIV-1NL4-3, C18 or C98. D36 Rev also had a 50–60% reduction in ability to express Rev-dependent reporter constructs in mammalian cells. In contrast, C64 Rev had only marginally decreased Rev function despite attenuated RRE binding. In D36 and C64, attenuated RRE binding was associated with rare amino acid changes at 3 highly conserved residues; Gln to Pro at position 74 immediately N-terminal to the Rev activation domain, and Val to Leu and Ser to Pro at positions 104 and 106 at the Rev C-terminus, respectively. In D36, reduced Rev function was mapped to an unusual 13 amino acid extension at the Rev C-terminus. Conclusion These findings provide new genetic and mechanistic insights important for Rev function, and suggest that Rev function, not Rev/RRE binding may be rate limiting for HIV-1 replication. In addition, attenuated rev alleles may contribute to viral attenuation and long-term survival of HIV-1 infection in a subset of SBBC members.

    Ionizing radiation frequently causes oxidative DNA damage in cells. It has been suggested that functions of the REV1 gene are induction of mutations and prevention of cell death caused by ionizing radiation through the damage bypass DNA replication. The gene product possesses a deoxycytidyl transferase activity, which is required for translesion DNA synthesis of a variety of damaged bases and an abasic site. To elucidate molecular mechanisms of the mutagenesis and translesion DNA synthesis, it is important to characterize the enzymatic properties of the REV1 protein. Here, we describe a novel method for purifying the recombinant human REV1 protein and the anzymatic properties of the protein. We established an efficient system for induction of the recombinant human REV1 protein in Escherichia coli cells. The REV1 protein was purified to homogeneity using nickel-chelating sepharose, heparin sepharose and superdex 200 chromatography. When purified by this method, REV1 protein is free of endo-, exonuclease and DNA polymerase activities. The purified REV1 protein is suitable for enzymological studies, and we used this to biochemical characterization. The REV1 protein inserts dCMP opposite templates G, A, T, C and an abasic site and inserts dGMP and dTMP opposite template G. Kinetic analysis provided evidence for high efficiency for dCMP insertion opposite template G and an abasic site, suggesting that the REV1 protein play a role in translesion DNA synthesis of an abasic site.

    We demonstrate the formation of shape-programmed, glassy origami structures using a single-layer photopolymer with two mechanically distinct phases. The latent origami pattern consisting of rigid, high cross-link density panels and flexible, low cross-link density creases is fabricated using a series of photomask exposures. Strong optical absorption of the polymer formulation creates depth-wise gradients in the cross-link density of the creases, enforcing directed folding which enables programming of both mountain and valley folds within the same sheet. These multiple photomask patterns can be sequentially applied because the sheet remains flat until immersed into a photopolymerizable monomer solution that differentially swells the polymer to fold and form the origami structure. After folding, a uniform photoexposure polymerizes the absorbed solution, permanently fixing the shape of the folded structure while simultaneously increasing the modulus of the folds. This approach creates sharp folds by mimicking the stiff panels and flexible creases of paper origami while overcoming the traditional trade-off of self-actuated materials that require low modulus for folding and high modulus for mechanical robustness. Using this process, we demonstrate a waterbomb base capable of supporting 1500 times its own weight.

    The purpose of this papers to present the results of CB3 phase of the VVER calculational benchmark with the recent evaluated nuclear data library ENDF/B-VI Rev.5 (1999). This results are compared with the obtained from the other participants in the calculations (Czech Republic, Finland, Hungary, Slovaquia, Spain and the United Kingdom). The phase (CB3) of the VVER calculation benchmark is similar to the Phase II-A of the OECD/NEA/INSC BUC Working Group benchmark for PWR. The cases without burnup profile (BP) were performed with the WIMS/D-4 code. The rest of the cases have been carried with DOTIII discrete ordinates code. The neutron library used was the ENDF/B-VI rev. 5 (1999). The WIMS/D-4 (69 groups) is used to collapse cross sections from the ENDF/B-VI Rev. 5 (1999) to 36 groups working library for 2-D calculations. This work also comprises the results of CB1 (obtained with ENDF/B-VI rev. 5 (1999), too) and CB3 for cases with Burnup of 30 MWd/TU and cooling time of 1 and 5 years and for case with Burnup of 40 MWd/TU and cooling time of 1 year.

    REV1 is a member of the Y-family DNA polymerases, but is atypical in utilizing only dCTP with a preference for guanine (G) as the template. Crystallography of the REV1-DNA-dCTP ternary complex has revealed a unique mechanism by which template G is evicted from the DNA helix and incoming dCTP is recognized by an arginine residue in an alpha-loop, termed the N-digit. To better understand functions of its individual amino acid residues, we made a series of mutant human REV1 proteins. We found that R357 and L358 play vital roles in template binding. Furthermore, extensive mutation analysis revealed a novel function of R357 for substrate discrimination, in addition to previously proposed specific interaction with incoming dCTP. We found that the binding pocket for dCTP of REV1 has also significant but latent affinity for dGTP. The results suggest that the positive charge on R357 could prevent interaction with dGTP. We propose that both direct and indirect mechanisms mediated by R357 ensure specificity for dCTP.

    Turbine wake meandering has considerable effects on the velocity deficit and turbulence intensity in the wake. However, the mechanism for wake meandering is still not well understood and low-order models cannot take into account the wake meandering effects accurately. A recent work by Kang, Yang and Sotiropoulos showed that the nacelle has a significant effect on the wake meandering of a hydrokinetic turbine. To examine the nacelle contributions to wake meandering and wake interactions in utility-scale wind farms, we simulate the atmospheric turbulent flow over the Horns Rev wind farm using large-eddy simulation with actuator type models. In a preliminary simulation on a coarse grid using actuator line model for turbine blades without a nacelle model, the computed power shows overall good agreement with field measurements. Fine grid simulations using an actuator surface model for turbine blades with and without a nacelle model are being carried out. The corresponding results will be presented with analysis on wake meandering dynamics using the technique proposed by Horward et al. and Foti et al.. This work was supported by DOE (DE-AC04-94AL85000), Xcel Energy (Grant RD4-13) and Sandia National Laboratories.

    An approach to the modeling of ligand-RNA complexes has been developed by combining three-dimensional structure-activity relationship (3D-SAR) computations with a docking protocol. The ability of 3D-SAR to predict bound conformations of flexible ligands was first assessed by attempting to reconstruct the known, bound conformations of phenyloxazolines complexed with human rhinovirus 14 (HRV14) RNA. Subsequently, the same 3D-SAR analysis was applied to the identification of bound conformations of aminoglycosides which associate with the Rev-binding element (RBE) RNA. Bound conformations were identified by parsing ligand conformational data sets with pharmacophores determined by the 3D-SAR analysis. These "bioactive" structures were docked to the receptor RNA, and optimization of the complex was undertaken by extensive searching of ligand conformational space coupled with molecular dynamics computations. The similarity between the bound conformations of the ligand from the 3D-SAR analysis and those found in the docking protocol suggests that this methodology is valid for the prediction of bound ligand conformations and the modeling of the structure of the ligand-RNA complexes.

    This report presents data from six aerial surveys of birds in the Horns Rev wind farm area in 2003. Including 16 surveys conducted before construction of the wind farm started and three during the construction phase, a total of 25 surveys have been performed in the area since August 1999. Up until August 2002 the study area was surveyed from 26 north-south oriented, parallel transect lines. After that time four short transects were added eastwards from the previously easternmost transect. From August 2002 slight adjustments to the transect lines in the wind farm area had to be made in order to avoid collision, as survey altitude was 76 m and wind turbines are 110 m to highest wing tip. The six surveys in 2003 were performed on 13 February, 16 March, 23 April, 5 September, 4 and 30 December. The operational phase of the wind farm commenced in 2002. Hence the six surveys from 2003 are all considered post-construction data sets. A preliminary evaluation of the potential impact of the wind turbines on bird distributions has been carried out by comparison of these data to those from the 16 pre-construction surveys. (au)

    Sierra Nevada Corporation (SNC) has developed an enhanced vision system utilizing fast-scanning 94 GHz radar technology to provide three-dimensional measurements of an aircraft's forward external scene topography. This threedimensional data is rendered as terrain imagery, from the pilot's perspective, on a Head-Up Display (HUD). The image provides the requisite "enhanced vision" to continue a safe approach along the flight path below the Decision Height (DH) in Instrument Meteorological Conditions (IMC) that would otherwise be cause for a missed approach. Terrain imagery is optionally fused with digital elevation model (DEM) data of terrain outside the radar field of view, giving the pilot additional situational awareness. Flight tests conducted in 2013 show that REVS™ has sufficient resolution and sensitivity performance to allow identification of requisite visual references well above decision height in dense fog. This paper provides an overview of the Enhanced Flight Vision System (EFVS) concept, of the technology underlying REVS, and a detailed discussion of the flight test results.

    Computational analysis of feline immunodeficiency virus (FIV) RNA sequences indicated that common FIV strains contain a rev response element (RRE) defined by a long unbranched hairpin with 6 stem-loop sub-domains, termed stem-loop A (SLA). To examine the role of the RNA secondary structure of the RRE, mutational analyses were performed in both an infectious FIV molecular clone and a FIV CAT-RRE reporter system. These studies disclosed that the stems within SLA (SA1, 2, 3, 4, and 5) of the RRE were critical but SA6 was not essential for FIV replication and CAT expression. These studies also revealed that the secondary structure rather than an antisense protein (ASP) mediates virus expression and replication in vitro. In addition, a single synonymous mutation within the FIV-RRE, SA3/45, reduced viral reverse transcriptase activity and p24 expression after transfection but in addition also showed a marked reduction in viral expression and production following infection.

    Pineal melatonin is synthesized with daily and seasonal rhythms following the hypothalamic clock-driven release of norepinephrine (NE). The pineal gland of rats and mice, like the biological clock, expresses a number of clock genes. However, the role of pineal clock elements in pineal physiology is still unknown. We examined the expression and regulation of several clock genes (Per1, Cry2, Bmal1 and Rev-erb alpha) under different lighting conditions or following adrenergic treatments in the Syrian hamster, a seasonal rodent. We found that Per1 and Cry2 genes were similarly regulated by the nocturnal release of NE: levels of Per1 and Cry2 mRNA displayed a nocturnal increase that was maintained after 2 days in constant darkness (DD) but abolished after 2 days under constant light (LL), a condition that suppresses endogenous NE release, or after an early night administration of the adrenergic antagonist propranolol. In contrast, Bmal1 and Rev-erb alpha exhibited a different pattern of expression and regulation. mRNA levels of both clock genes displayed a marked daily variation, maintained in DD, with higher values at midday for Bmal1 and at day/night transition for Rev-erb alpha. Remarkably, the daily variation of both Bmal1 and Rev-erb alpha mRNA was maintained in LL conditions and was not affected by propranolol. This study confirms the daily regulation of Per1 and Cry2 gene expression by NE in the pineal gland of rodents and shows for the first time that a second set of clock genes, Bmal1 and Rev-erb alpha are expressed with a circadian rhythm independent of the hypothalamic clock-driven noradrenergic signal.

    2000-05-15

    As part of an overall Environmental Impact Assessment (EIA) undertaken in connection with a planned 150 MW offshore wind farm at Horns Rev, an assessment was made of the effects the wind farm would have on the water quality in the area. This EIA study was drawn up in accordance with the guidelines laid down by the Danish Ministry of Environment and Energy in the publication 'Guidelines for the preparation of EIA studies for offshore wind farms'. Horns Rev is situated off Blaevands Huk, which is Denmark's most westerly point. It is a shallow reef with water depths between 2 and 9 metres and is primarily composed of sand, gravel and pebbles. Only local and minor changes are anticipated in connection with the currents, sediments and wave conditions during the production phase. These will occur in the immediate vicinity of the individual foundations. For these reasons, no changes are expected in the water quality. This also includes also the pelagic primary production and the occurrence of plankton in the area. Increased local copper contamination of phytoplankton and zooplankton may be expected during the production phase, as a result of the total annual discharge of 206 kg copper from the slip-rings in the wind turbines. The contamination will potentially result in a local reduction of the pelagic primary production and changes in the species composition of the plankton. The wind turbines will be sandblasted and painted once during their lifetime, as part of the routine maintenance. The sandblasting and painting will lead to a temporary spill of paint, paint waste and sand. The impacts on water quality and plankton production are unknown. It is recommended that factors such as the toxicity of the paint be investigated, and that spills and the impact of waste be reduced as much as possible. The water quality and the plankton in the wind farm area and along the cable line's passage to shore through the international protected area, will only be

    In this paper, we design an octahedral spherical Au hohlraum for CH Rev5 ignition capsule [S. W. Haan et al., Phys. Plasmas 18, 051001 (2011)] by using the initial design method and two-dimensional (2D) simulations, and we investigate its laser entrance hole (LEH) closure and laser-plasma instabilities (LPI) by using a spherical hohlraum with two different-size LEHs via 2D simulations. The designed spherical hohlraum with RH=5 RC, RL=1.2 mm , and RL*=2 RL requires an ignition laser pulse of 1.92 MJ in energy and 670 TW in peak power, where RH, RC, RL, and RL* are radii of the spherical hohlraum, capsule, LEH, and the cylindrical LEH outer ring, respectively. From 2D simulations, the closure and opening up of LEH are clearly obtained. The LEH closure and its rate are strongly connected to the radiation pulse, while the LEH opening-up and its rate are strongly connected to the laser pulse. The smallest radius of LEH during closure is 0.6 mm before opening up, which leaves enough room for arranging the laser beams with a radius of 0.5 mm in our design. By using a post-process code for LPI, a relatively high stimulated Brillouin scattering fraction and a very low stimulated Raman scattering fraction are predicted, which may be due to the neglection of three-dimensional density gradients of the ablative flow along the laser transportation in 2D simulations. This work provides the energy and power references for the future ignition laser facility which uses octahedral spherical hohlraums as ignition targets.

  14. HRensembleHR. High resolution ensemble for Horns Rev. Final project report; Offshore wind power

    Energy Technology Data Exchange (ETDEWEB)

    2010-03-15

    The wind farm output of an offshore-farm such as Horns Rev changes between nearly constant output to highly variable power output. A balance responsible will therefore benefit from knowing the variability of a wind farm in advance. Some understanding of the observed variability and the corresponding forecast error on offshore wind farms had been gathered in the past few years, while a large fraction (about 60%) of the error still lacked understanding and required further intense research. This was the outset at the beginning of the HREnsemble project. Results from the wave study, variability study, ocean coupling, findings from the sensitivity experiments, the iEnKF short-term forecast and finally the demonstration phase have given significant synergy. The most basic research result in the project is that the two empirical mode decomposition approaches, Hilbert-Huang and later the Ensemble Empirical Mode Decomposition (EEMD). Both approaches confirmed that significant variability exists in offshore conditions. It was found that the variability of the short time-scales (24 minutes) are either not explicitly visible in the grid-scale of the NWP models or in the best case significantly smoothed out in all of the tested model configurations. If we interpret 2/3 of the variability due to vertical waves not present in the mean flow and 1/3 of the variability due to meso-scale weather, then the model results and EEMD are consistent. We can however not verify this theory. At present we do not know if EEMD counts neither the events correct nor whether the ensemble forecast suppresses variability. The existence of variability above the time-scale related to friction between ocean waves and air can in fact explain some of the inconsistent results published in the literature and set a question mark behind the correctness of the calculation of friction in wave, ocean and weather modelling.

    This paper describes the development of a wind turbine (WT) component lifetime fatigue load variation map within an offshore wind farm. A case study on the offshore wind farm Horns Rev I is conducted with this purpose, by quantifying wake effects using the Dynamic Wake Meandering (DWM) method, which has previously been validated based on CFD, Lidar and full scale load measurements. Fully coupled aeroelastic load simulations using turbulent wind conditions are conducted for all wind directions and mean wind speeds between cut-in and cut-out using site specific turbulence level measurements. Based on the mean wind speed and direction distribution, the representative 20-year lifetime fatigue loads are calculated. It is found that the heaviest loaded WT is not the same when looking at blade root, tower top or tower base components. The blade loads are mainly dominated by the wake situations above rated wind speed and the highest loaded blades are in the easternmost row as the dominating wind direction is from West. Regarding the tower components, the highest loaded WTs are also located towards the eastern central location. The turbines with highest power production are, not surprisingly, the ones facing a free sector towards west and south. The power production results of few turbines are compared with SCADA data. The results of this paper are expected to have significance for operation and maintenance planning, where the schedules for inspection and service activities can be adjusted to the requirements arising from the varying fatigue levels. Furthermore, the results can be used in the context of remaining fatigue lifetime assessment and planning of decommissioning.

    Full Text Available The live B. melitensis Rev.1 strain is considered the best vaccine available for the prophylaxis of brucellosis in small ruminants, especially when used at the standard dose by the conjunctival route. In the present study a 1´ 10(9 CFU dose for both sheep and goats conjunctivally vaccinated was tested to evaluate the duration of serological responses. Conjunctival vaccination with Rev. 1 performed in adult animals induced a rapid rise in serological titres as measured by Rose Bengal Plate Test (RBPT, Complement Fixation Test (CF and Modified Rose Bengal Plate Test (MRBPT. Titres then decreased and became negative in most animals by four months after vaccination (except MRBPT. The goats responded better to the vaccination than the sheep as one month after vaccination 100% of the goats revealed positive results to RB and RBM and 93.4% to FC test. The RBM was the one that detected more positive animals along the study.

    The continuous 1D defects of an isotropic homogeneous material in an Euclidean 3D space are classified by a construction method, the Volterra process (VP). We employ the same method to classify the continuous 2D defects (which we call \\textit{cosmic forms}) of a vacuum in a 4D maximally symmetric spacetime. These defects fall into three different classes: i)- $m$-forms, akin to 3D space disclinations, related to ordinary rotations and analogous to Kibble's global cosmic strings (except that being continuous any deficit angle is allowed); ii)- $t$-forms, related to Lorentz boosts (hyperbolic rotations); iii)- $r$-forms, never been considered so far, related to null rotations. A detailed account of their metrics is presented. Their inner structure in many cases appears as a non-singular \\textit{core} separated from the outer part by a timelike hypersurface with distributional curvature and/or torsion, yielding new types of geometrical interactions with cosmic dislocations and other cosmic disclinations.

    In the "Comments on Phys. Rev. D89, 097101 (2014)", the Author presents a number of studies to conjecture that the analysis by the HERMES Collaboration presented in Phys. Rev. D89, 097101 (2014) likely suffers from effects that invalidate the leading-order analysis used in that publication. In our opinion, the Author has drawn erroneous conclusions. We present below a discussion of his arguments and the results from a repetition of that analysis using a range of parton distribution sets. The spread in those results precludes credible conclusions and demonstrates the sensitivity of the analysis to poorly known input data (unfavored FFs, strange-quark distributions, and mixed singlet and nonsinglet quantities).

  10. A new Method to Estimate the Representative Elementary Volume (REV) for Porosity in Heterogeneous Karst Aquifers Using Geographic Information Systems

    Science.gov (United States)

    Gross, M. R.; Manda, A. K.

    2004-12-01

    Karst limestones are characterized by solution-enhanced macropores and conduits that lead to exceptional heterogeneity at the aquifer scale. The interconnected network of solution cavities often results in a conduit flow regime that bypasses the less permeable rock matrix. Efforts to manage and protect karst aquifers, which are vital water resources in many parts of the world, will benefit from meaningful characterizations of the heterogeneity inherent in these formations. To this end, we propose a new method to estimate the representative elementary volume (REV) for macroporosity within karst aquifers using techniques borrowed from remote sensing and geospatial analysis. The REV represents a sampling window in which numerous measurements of a highly-variable property (e.g., porosity, hydraulic conductivity) can be averaged into a single representative value of statistical and physical significance. High-resolution borehole images are classified into binary images consisting of pixels designated as either rock matrix or pore space. A two-dimensional porosity is calculated by summing the total area occupied by pores within a rectangular sampling window placed over the binary image. Small sampling windows quantify the heterogeneous nature of porosity distribution in the aquifer, whereas large windows provide an estimate of overall porosity. Applying this procedure to imagery taken from the Biscayne aquifer of south Florida yields a macroporosity of ~40%, considerably higher than the ~28% porosity measured from recovered core samples. Geospatial analysis may provide the more reliable estimate because it incorporates large solution cavities and conduits captured by the borehole image. The REV is estimated by varying the size of sampling windows around prominent conduits and evaluating the change in porosity as a function of window size. Average porosities decrease systematically with increasing sampling size, eventually converging to a constant value and thus

    Certain components and functions of the immune system, most notably cytokine production and immune cell migration, are under circadian regulation. Such regulation suggests that circadian rhythms may have an effect on disease onset, progression, and resolution. In the vesicular stomatitis virus (VSV)-induced encephalitis model, the replication, caudal penetration, and survivability of intranasally applied VSV depends on both innate and adaptive immune mechanisms. In the current study, we investigated the effect of circadian time of infection on the progression and outcome of VSV-induced encephalitis and demonstrated a significant decrease in the survival rate in mice infected at the start of the rest cycle, zeitgeber time 0 (ZT0). The lower survival rate in these mice was associated with higher levels of circulating chemokine (C-C motif) ligand 2 (CCL2), a greater number of peripherally derived immune cells accumulating in the olfactory bulb (OB), and increased production of proinflammatory cytokines, indicating an immune-mediated pathology. We also found that the acrophase of molecular circadian clock component REV-ERBα mRNA expression in the OB coincides with the start of the active cycle, ZT12, when VSV infection results in a more favorable outcome. This result led us to hypothesize that REV-ERBα may mediate the circadian effect on survival following VSV infection. Blocking REV-ERBα activity before VSV administration resulted in a significant increase in the expression of CCL2 and decreased survival in mice infected at the start of the active cycle. These data demonstrate that REV-ERBα-mediated inhibition of CCL2 expression during viral-induced encephalitis may have a protective effect.

    Circadian rhythms are strongly affected by drugs. In rodents, chronic methamphetamine (METH) intake changes circadian activity rhythms, mainly by altering light synchronization that generates the expression of a free-running rhythm with a period longer than 24 h and a second behavioral component that is independent of the main suprachiasmatic (SCN) clock. Although a number of clock genes do not appear to be involved in the effects of METH on circadian behavior, the molecular clockwork controlling these changes is still unclear. Therefore, we investigated the role of the clock gene Rev-Erbα in METH-induced behavioral and molecular responses using knockout mice and their wild-type littermates. Chronic intake of METH alters period circadian behavior of wild-type mice. However, in mice lacking the clock gene Rev-Erbα METH had no effect on their behavioral rhythms. Furthermore, PER2 bioluminescence rhythms in two extra-SCN brain oscillators, the dorsomedial hypothalamus and the habenula, were altered by METH in wild type but not in KO mice. Together, the present results implicate Rev-Erbα in the modulation of the circadian responses to METH and may provide a better comprehension into the mechanisms underlying circadian alterations provoked by drug addiction.

    Brucellosis is one of the most important zoonotic diseases and is a significant cause of abortion in animals. Brucella melitensis strain Rev. 1 is recommended as the most effective vaccine for small ruminants but the application of full doses in adult animals is restricted. This study was conducted to determine a proper reduced dose of vaccine which confers protection but which is not abortifacient in Iranian fat-tailed sheep. A total of 51 non-vaccinated pregnant ewes were divided into three main groups and several subgroups. Ewes in different groups were vaccinated at different stages of pregnancy and various subgroups were subcutaneously immunised with different quantities of the micro-organism (7.5 × 10(6), 10(6), 5 × 10(5)). Ewes again became pregnant a year later and were challenged with the wild-type strain to evaluate the protection conferred. Results revealed that the proportion of vaccination-induced abortions was significantly higher in ewes immunised with 7.5 × 10(6) Rev. 1 organisms than in those which received 10(6) or 5 × 10(5) bacteria. While 80% of non-vaccinated ewes aborted after challenge, none of the vaccinated ewes aborted post-challenge. This study indicated that a reduced dose of Rev. 1 vaccine containing 10(6) or 5 × 10(5) live cells could be safely used to induce protection in Iranian fat-tailed sheep at various stages of pregnancy.

    Preterm birth is the most important single determinant of adverse outcome in the United Kingdom; one in every 70 babies (1.4%) is born before 32 weeks (very preterm), yet these births account for over half of infant deaths.Deferring cord clamping allows blood flow between baby and placenta to continue for a short time. This often leads to increased neonatal blood volume at birth and may allow longer for transition to the neonatal circulation. Optimal timing for clamping the cord remains uncertain, however. The Cochrane Review suggests that deferring umbilical cord clamping for preterm births may improve outcome, but larger studies reporting substantive outcomes and with long-term follow-up are needed. Studies of the physiology of placental transfusion suggest that flow in the umbilical cord at very preterm birth may continue for several minutes. This pilot trial aims to assess the feasibility of conducting a large randomised trial comparing immediate and deferred cord clamping in the UK. Women are eligible for the trial if they are expected to have a live birth before 32 weeks gestation. Exclusion criteria are known monochorionic twins or clinical evidence of twin-twin transfusion syndrome, triplet or higher order multiple pregnancy, and known major congenital malformation. The interventions will be cord clamping within 20 seconds compared with cord clamping after at least two minutes. For births with cord clamping after at least two minutes, initial neonatal care is at the bedside. For the pilot trial, outcomes include measures of recruitment, compliance with the intervention, retention of participants and data quality for the clinical outcomes.Information about the trial is available to women during their antenatal care. Women considered likely to have a very preterm birth are approached for informed consent. Randomisation is close to the time of birth. Follow-up for the women is for one year, and for the children to two years of age (corrected for gestation

    We estimated the key molecules related to Type 2 diabetes mellitus (T2DM) in adipose, liver, and muscle tissues, from nonobese diabetic Goto-Kakizaki (GK) rats and their Wistar controls, by computationally analyzing the expression profiles in open source data. With the aid of information from previous reports, Rev-erbα in adipose tissue emerged as one of the most plausible candidates. Here, in animal models, including GK rats surgically treated to ameliorate T2DM, we examined the association of Rev-erbα in adipose tissue with T2DM progression. After analyses of the Rev-erbα mRNA expression in the adipose tissue of our animal models, we compared the Rev-erbα protein expression levels in the adipose, liver, and muscle tissues of GK and Wistar controls at the ages of 1 mo (M), 3M, and 6M. The Rev-erbα protein levels in adipose tissue showed a distinctive pattern, with the negative correlation of an increasing trend in GK rats, and a decreasing trend in Wistar rats during aging, from those in liver and muscle tissues. Moreover, dysregulation of the circadian Rev-erbα expression in the adipose tissue of 6-mo-old GK rats was also observed. In particular, we ameliorated T2DM in GK rats by gastric bypass surgery, and revealed that T2DM amelioration in diabetic GK rats was associated with improved circadian Rev-erbα expression, in a comparison between the surgically treated and untreated GK rats. The roles of Rev-erbα in adipose tissue were further investigated by observations of Rev-erbα-related molecules, with reference to previous reports.

D 50, 5491 (1994)] on elastic electron-proton scattering. This work is motivated by recent progress in calculating the corresponding radiative corrections and by the apparent discrepancy between the Rosenbluth and polarization transfer measurements of the proton electromagnetic form factors. New, corrected values for the scattering cross sections are presented, as well as a new form factor fit in the $Q^2$ range from 1 to 8.83 $\\text{GeV}^2$. We also provide a complete set of revised formulas to account for radiative corrections in single-arm measurements of unpolarized elastic electron-proton scattering.

    Undocumented immigrant young adults growing up in the United States face significant challenges. For those qualified, the Deferred Action for Childhood Arrivals (DACA) program's protections may alleviate stressors, with implications for their mental health and wellbeing (MHWB). We conducted nine focus groups with 61 DACA-eligible Latinos (ages 18-31) in California to investigate their health needs. Participants reported MHWB as their greatest health concern and viewed DACA as beneficial through increasing access to opportunities and promoting belonging and peer support. Participants found that DACA also introduced unanticipated challenges, including greater adult responsibilities and a new precarious identity. Thus, immigration policies such as DACA may influence undocumented young adults' MHWB in expected and unexpected ways. Research into the impacts of policy changes on young immigrants' MHWB can guide stakeholders to better address this population's health needs. MHWB implications include the need to reduce fear of deportation and increase access to services.

    For almost 45 years, the experience of Jewish children who were hidden during World War II was considered to be of little importance, particularly with respect to what had taken place in the concentration camps. Their very history was ignored in the many accounts of the Holocaust. It was only at the end of the 1980s that their experience began to be thought of as potentially traumatic. In this paper, the authors report on their psychoanalytical research project concerning the psychological outcomes of those experiences that had remained concealed for such an extraordinarily long latency period. The results are based on the analysis of 60 accounts and on psychoanalytically-oriented group work. The authors show that the trauma experienced by those hidden children was triggered by the retroactive effect of a deferred action [après-coup]. Copyright © 2010 Institute of Psychoanalysis.

We generalize this method to the two-party multiqubit case and the multiparty case. We also compare the local implementation of nonlocal block operations with the remote implementation of local operations [Huelga , Phys. Rev.

    The Simulation drilling system provides a good service for the enterprises and the emergency departments at present. However, it still has quite a few drawbacks. Such as the lack of modern graphic pipeline support, the excessive computation of scene rendering on the condition of multiple lights, the poor rendering effects caused by that it cannot make full use of hardware etc. In order to solve those problems, this paper is designed and implemented with a deferred shading pipeline for simulation drilling system. This pipeline is based on the Blinn-Phong lighting model, which builds a compressed G-buffer layout and uses Light volume to model the light source. The final experiment indicates that under the multiple lights circumstances, the deferred shading expressed in this paper will be more efficient than the conventional forward shading.%模拟演练系统为企业和应急部门提供了强大的服务,然而目前的模拟演练系统中存在缺乏现代图形流水线,多光源情况下存在场景渲染计算量过多,不能充分利用硬件而导致的渲染效果差等问题。为了解决这些问题,本文针对模拟演练系统,设计和实现了延迟渲染流水线,它依据Blinn-Phong光照模型,构建了一种压缩的G-Buffer布局,并使用Light Volume来对光源进行建模。最后实验表明,在多光源情况下,此文中提出的延迟渲染比传统的正向渲染有更高的效率。

    To verify pore-scale modelling approach for determination of soil saturated hydraulic conductivity properties we scanned three cylindrical soil samples taken from A, Ah and B horizons using X-ray microtomography method. Resulting 3D soil images with resolutions of 15.25-20.96 μm were segmented into pores and solids and their maximum inscribed cube subvolumes were used as input data for three major pore-scale modelling methods to simulate saturated flow - lattice-Boltzmann method, finite-difference solution of the Stokes problem, and pore-network model. Provided that imaging resolution is high enough to capture the backbone of effective porosity and the main conducting pores all three methods resulted in simulated soil permeabilities close to experimental values for Ah and B samples. The resolution of A sample was not enough for an accurate modelling and we concluded that this soil requires multi-scale imaging to cover all relevant heterogeneities. We demonstrate that popular SWV method to choose segmentation threshold resulted in oversegmentation and order of magnitude higher permeability values. Careful manual thresholding combined with local segmentation algorithm provided much more accurate results. Detailed analysis of water retention curves showed that air-filled porosity at relevant pressure stages cannot be used for verification of the segmentation results. Representativity analysis by simulating flow in increasing soil volume up to 2.8 cm3 revealed no representative elementary volume (REV) within Ah sample and non-uniqueness of REV for B sample. The latter was explained by soil structure non-stationarity. We further speculate that structures soil horizons can exhibit no REV at all. We discuss numerous advantages of coupled imaging and pore-scale modelling approach and show how it can become a successor of the conventional soil coring method to parametrize large scale continuum models.

  10. Stimulation of nuclear receptor REV-ERBs regulates tumor necrosis factor-induced expression of proinflammatory molecules in C6 astroglial cells

    Under physiological conditions, astrocytes maintain homeostasis in the CNS. Following inflammation and injury to the CNS, however, activated astrocytes produce neurotoxic molecules such as cytokines and chemokines, amplifying the initial molecular-cellular events evoked by inflammation and injury. Nuclear receptors REV-ERBα and REV-ERBβ (REV-ERBs) are crucial in the regulation of inflammation- and metabolism-related gene transcription. The current study sought to elucidate a role of REV-ERBs in rat C6 astroglial cells on the expression of inflammatory molecules following stimulation with the neuroinflammatory cytokine tumor necrosis factor (TNF). Stimulation of C6 cells with TNF (10 ng/ml) significantly increased the mRNA expression of CCL2, interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), and matrix metalloprotease (MMP)-9, but not fibroblast growth factor-2 (FGF-2), cyclooxygenase-2 (COX-2) and MMP-2. Treatment with either REV-ERB agonists GSK4112 or SR9009 significantly blocked TNF-induced upregulation of CCL2 mRNA and MMP-9 mRNA, but not IL-6 mRNA and iNOS mRNA expression. Furthermore, treatment with RGFP966, a selective histone deacetylase 3 (HDAC3) inhibitor, potently reversed the inhibitory effects of GSK4112 on TNF-induced expression of MMP-9 mRNA, but not CCL2 mRNA. Expression of Rev-erbs mRNA in C6 astroglial cells, primary cultured rat cortical and spinal astrocytes was confirmed by reverse transcription polymerase chain reaction. Together, the findings demonstrate an anti-inflammatory effect, downregulating of MMP-9 and CCL2 transcription, of astroglial REV-ERBs activation through HDAC3-dependent and HDAC3-independent mechanisms. - Highlights: • Rev-erbα mRNA and Rev-erbβ mRNA are expressed in C6 astroglial cells. • TNF increases the expression of CCL2, IL-6, MMP-9 and iNOS mRNA. • REV-ERB activation inhibits CCL2 mRNA and MMP-9 mRNA expression. • HDAC3 activity is involved in the inhibitory effect of REV-ERB on MMP-9 induction.

    The instant form and the front form of relativistic dynamics proposed by Dirac (Rev Mod Phys 21:392-399, 1949) can be linked by introducing an interpolating angle. The instant form dynamics (IFD) provides a traditional approach evolved from non-relativistic dynamics and makes a close contact with Euclidean space developing temperature-dependent quantum field theory, lattice QCD, etc. The front form dynamics, now known as the light-front dynamics (LFD), however, works strictly in Minkowski space and provides useful frameworks to study deep inelastic scattering, parton distribution functions, deeply virtual Compton scattering, generalized parton distributions, etc. We present the recent development of the interpolation between IFD and LFD and discuss ramifications from this development.

  15. Tidal Forms

    2003-04-01

    We give an overview of some recent investigations on the mechanics of the processes whereby forms develop in tidal environments. The viewpoint taken here is mechanistic. Some of the questions which deserve an answer may be summarised as follows: i) do tidal channels tend to some altimetric long term equilibrium? ii) why are they typically convergent and weakly meandering? iii) how is such equilibrium affected by the hydrodynamics and morphodynamics of tidal inlets? iv) what is the hydrodynamic and morphodynamic role played by tidal flats adjacent to the channels? Some of the above questions have received a considerable attention in the last few years. Schuttelaars and de Swart (1996), Lanzoni and Seminara (2002) and, more recently, Bolla Pittaluga (2003) have investigated the first problem. In particular, the latter two contributions have shown that a straight tidal channel connected to a tidal sea at one end and closed at the other end tends to reach a long term equilibrium profile, which is slightly concave seaward and convex landward where a beach forms. The equilibrium profile is strongly sensitive to the harmonic content of the tidal forcing as well as to the value of sediment concentration established by the coastal hydrodynamics in the far field of the inlet region. Less important are the effect of channel convergence and the role of settling lag in the transport of suspended load. Insufficient attention has been devoted to the understanding of what mechanisms control channel convergence and meandering, though some similarities and differences between tidal and fluvial channels have emerged from some recent works. In particular, free bars form in tidal channels due to an instability mechanism essentially similar to that occurring under steady conditions though the oscillatory character of the flow field makes the bar pattern non migrating (Seminara and Tubino, 2001). Similarly, forced bars in curved tidal channels are driven by the development of

    The CGV26 and CGV2631 strains are novel engineered Brucella melitensis Rev.1 mutant strains deleted for the bp26 gene or for both bp26 and omp31 genes, respectively, coding for proteins of diagnostic significance. The residual virulence and immunogenicity of both mutants were compared to the parental Rev.1 strain in sheep after subcutaneous or conjunctival vaccination. The deletion of the bp26 gene or both bp26 and omp31 genes had no significant effect on the intracellular survival of the Rev.1 strain in ovine macrophage cultures. The kinetics of infection induced by both mutants in sheep was similar to the Rev.1 strain, and inoculation by the subcutaneous route produced wider and more generalized infections than the conjunctival route. All strains were cleared from lymph nodes and organs within 3 months after inoculation. The CGV26 and CGV2631 mutants induced both specific systemic antibody response and lymphoproliferation in sheep. The kinetics of the responses induced by the mutants was quite similar to that of the parental Rev.1 strain, except for the intensity of the lymphoproliferative response, which was attenuated for the CGV2631 mutant. In conclusion, the residual virulence of both CGV26 and CGV2631 mutants in sheep was similar to that of the parental Rev.1 vaccine strain. These mutants induced also significant specific antibody and cell-mediated immunity in sheep and are suitable to be evaluated as potential vaccine candidates against B. melitensis and B. ovis infections in sheep.

    The policy of deferred-tax on commercial endowment insurance is of great importance to the establishment and im⁃provement of pension system. In this paper, two different individual consumption-saving models, which are named as non-tax deferred model and tax deferred model, are built separately to study the effect of deferred-tax policy on optimal individual choices. Through modeling process, we come to the following conclusions:If the deferred tax rate equals the working period tax rate, individual demand for annuity insurance will increase, and yet the other demand and his/her expected utility will keep sta⁃ble. In this situation, the deferred tax policy is an Pareto improvement;If it is less than the working period tax rate, individual working period consumption, demand for annuity insurance and his expected utility will increase while individual bank saving will decrease;If it is greater than the working period tax rate, individual working period consumption, demand for annuity in⁃surance and his/her expected utility will decrease but individual bank savings will increase.%商业养老保险税收递延政策对完善养老保障体系具有重要意义。文章分别在无税收递延政策和有税收递延政策情形下建立了个体消费—储蓄模型,通过对比两种情形下的个体最优行为,分析了税收递延政策对个体行为的影响。研究表明:当递延税收税率与工作期税率相等时,个体年金保险需求增加、其他行为及效用不变,此时税收递延政策是一种帕累托改进;当递延税收税率小于工作期税率时,个体当期消费、年金保险需求及效用增加,银行存款减少;当递延税收税率大于工作期税率时,个体当期消费、年金保险需求及效用减少,银行存款增加。

    The purpose of Operational Circular No. 2 (Rev. 1) is to contribute to the protection of people and property by defining the conditions of access to the Organization's fenced sites. The behaviours that cannot be tolerated under any circumstances are: use of CERN access cards by people, other than the cardholders themselves, in order to gain access to facilities without having attended the required safety course; speeding, particularly on Route Gregory and Route Weisskopf; driving in and out of the site on the wrong side of the road; parking on spaces set aside for the disabled; nuisance parking, especially in the proximity of the restaurants; dumping of wrecked vehicles. As the aforementioned instances of non-compliance can lead to dangerous situations, the Organization reserves the right to apply the penalties provided for under paragraph 26 of Operational Circular No. 2 (Rev. 1), namely to refuse access to the site to people and/or their vehicles deemed to be in infringement of the circu...

    We analyzed RNA splice site usage in three HIV-1 subtype B primary isolates through reverse transcriptase polymerase chain reaction (RT-PCR) amplification of spliced RNAs using a fluorescently labeled primer, with computerized size determination and quantification of PCR products, which were also identified by clone sequencing. In one isolate, P2149-3, unusual and unreported spliced transcripts were detected. This isolate preferentially used for rev RNA generation a 3' splice site (3'ss) located five nucleotides upstream of A4a, previously identified only in a T cell line-adapted virus and in a group O isolate, and designated A4d. P2149-3 also used an unreported 3'ss for rev RNA generation, designated A4h, located 20 nucleotides upstream of 3'ss A4c. Additionally, unusual nef RNAs using 3'ss A5a and A7a and with exon composition 1.3.7 were identified. The identification of several unusual and unreported spliced transcripts in an HIV-1 primary isolate suggests a greater diversity of splice site usage in HIV-1 than previously appreciated.

  4. Canonical form of Nambu–Poisson bracket: A pedestrian approach

    2011-12-01

    In the seventies, Nambu (Phys. Rev. D7, 2405 (1973)) proposed a new approach to classical dynamics based on an -dimensional Nambu–Poisson (NP) manifold replacing the primitive even-dimensional Poisson manifold and on –1 Hamiltonians in place of a single Hamiltonian. This approach has had many promoters including Bayen and Flato (Phys. Rev. D11, 3049 (1975)), Mukunda and Sudarshan (Phys. Rev. D13, 2846 (1976)), and Takhtajan (Comm. Math. Phys. 160, 295 (1994)) among others. While Nambu had originally considered = 3, the illustration of his ideas for = 4 and 6 was given by Chatterjee (Lett. Math. Phys. 36, 117 (1996)) who observed that the classical description of dynamical systems having dynamical symmetries is described elegantly by Nambu’s formalism of mechanics. However, his considerations do not quite yield the beautiful canonical form conjectured by Nambu himself for the -ary NP bracket. By making a judicious choice for the ‘extra constant of motion’ of namely, and , which are the orientation angles in Kepler problem and isotropic harmonic oscillator (HO) respectively, we show that the dynamical systems with dynamical symmetries can be recast in the beautiful form suggested by Nambu. We believe that the techniques used and the theorems suggested by us in this work are of general interest because of their involvement in the transition from Hamiltonian mechanics to Nambu mechanics.

  5. A numerical-statistical approach to determining the representative elementary volume (REV of cement paste for measuring diffusivity

    2010-12-01

    Full Text Available Concrete diffusivity is a function of its microstructure on many scales, ranging from nanometres to millimetres. Multi-scale techniques are therefore needed to model this parameter. Representative elementary volume (REV, in conjunction with the homogenization principle, is one of the most common multi-scale approaches. This study aimed to establish a procedure for establishing the REV required to determine cement paste diffusivity based on a three-step, numerical-statistical approach. First, several series of 3D cement paste microstructures were generated with HYMOSTRUC3D, a cement hydration and microstructure model, for different volumes of cement paste and w/c ratios ranging from 0.30 to 0.60. Second, the finite element method was used to simulate the diffusion of tritiated water through these microstructures. Effective cement paste diffusivity values for different REVs were obtained by applying Fick’s law. Finally, statistical analysis was used to find the fluctuation in effective diffusivity with cement paste volume, from which the REV was then determined. The conclusion drawn was that the REV for measuring diffusivity in cement paste is 100x100x100 μm3.

    The HIV Rev protein routes viral RNAs containing the Rev Response Element (RRE) through the Crm1 nuclear export pathway to the cytoplasm where viral proteins are expressed and genomic RNA is delivered to assembling virions. The RRE assembles a Rev oligomer that displays nuclear export sequences (NESs) for recognition by the Crm1-Ran(GTP) nuclear receptor complex. Here we provide the first view of an assembled HIV-host nuclear export complex using single-particle electron microscopy. Unexpectedly, Crm1 forms a dimer with an extensive interface that enhances association with Rev-RRE and poises NES binding sites to interact with a Rev oligomer. The interface between Crm1 monomers explains differences between Crm1 orthologs that alter nuclear export and determine cellular tropism for viral replication. The arrangement of the export complex identifies a novel binding surface to possibly target an HIV inhibitor and may point to a broader role for Crm1 dimerization in regulating host gene expression.

  8. MMW radar enhanced vision systems: the Helicopter Autonomous Landing System (HALS) and Radar-Enhanced Vision System (REVS) are rotary and fixed wing enhanced flight vision systems that enable safe flight operations in degraded visual environments

    Sierra Nevada Corporation (SNC) has developed rotary and fixed wing millimeter wave radar enhanced vision systems. The Helicopter Autonomous Landing System (HALS) is a rotary-wing enhanced vision system that enables multi-ship landing, takeoff, and enroute flight in Degraded Visual Environments (DVE). HALS has been successfully flight tested in a variety of scenarios, from brown-out DVE landings, to enroute flight over mountainous terrain, to wire/cable detection during low-level flight. The Radar Enhanced Vision Systems (REVS) is a fixed-wing Enhanced Flight Vision System (EFVS) undergoing prototype development testing. Both systems are based on a fast-scanning, threedimensional 94 GHz radar that produces real-time terrain and obstacle imagery. The radar imagery is fused with synthetic imagery of the surrounding terrain to form a long-range, wide field-of-view display. A symbology overlay is added to provide aircraft state information and, for HALS, approach and landing command guidance cuing. The combination of see-through imagery and symbology provides the key information a pilot needs to perform safe flight operations in DVE conditions. This paper discusses the HALS and REVS systems and technology, presents imagery, and summarizes the recent flight test results.

    Guanine is the most easily oxidized of the four DNA bases, and contiguous guanines (GG) in a sequence are more readily oxidized than a single guanine in a sequence. Continued oxidation of GGs results in a contiguous oxidized guanine lesion. Two contiguous 2,5-diamino-4H-imidazol-4-ones, an oxidized form of guanine that hydrolyses to 2,2,4-triamino-5(2H)-oxazolone (Oz), are detected following the oxidation of GG. In this study, we analysed translesion synthesis (TLS) across two contiguous Oz molecules (OzOz) using Klenow Fragment exo(-) (KF exo(-)) and DNA polymerases (Pols) α, β, ζ, η, ι, κ and REV1. We found that KF exo(-) and Pols α, β, ι and REV1 inserted one nucleotide opposite the 3' Oz of OzOz and stalled at the subsequent extension, and that Pol κ incorporated no nucleotide. Pol η only inefficiently elongated the primer up to full-length across OzOz; the synthesis of most DNA strands stalled at the 3' or 5' Oz of OzOz. Surprisingly, however, Pol ζ efficiently extended the primer up to full-length across OzOz, unlike the other DNA polymerases, but catalysed error-prone nucleotide incorporation. We therefore believe that Pol ζ is required for efficient TLS of OzOz. These results show that OzOz obstructs DNA synthesis by DNA polymerases except Pol ζ.

    This design-only conceptual design report (DOCDR) was prepared to support a funding request by the Department of Energy (DOE)-Office of Fissile Material Disposition (OFMD) for engineering design of the Pit Disassembly and Conversion Facility (PDCF) Project No. 99-D-141. The PDCF will be used to disassemble the nation`s inventory of surplus nuclear weapons pits and convert the plutonium recovered from those pits into a form suitable for storage, international inspection, and final disposition. The PDCF is a complex consisting of a hardened building that will contain the plutonium processes in a safe and secure manner, and conventional buildings and structures that will house support personnel, systems, and equipment. The PDCF uses the Advanced Recovery and Integrated Extraction System (ARIES), a low waste, modular pyroprocessing system to convert pits to plutonium oxide. The PDCF project consists of engineering and design, and construction of the buildings and structures, and engineering and design, procurement, installation, testing and start-up of equipment to disassemble pits and convert plutonium in pits to oxide form. The facility is planned to operate for 10 years, averaging 3.5 metric tons (3.86 tons) of plutonium metal per year. On conclusion of operations, the PDCF will be decontaminated and decommissioned.

    Full Text Available Abstract Background Recombinant gas vesicles (r-GV from Halobacterium sp. strain SD109 expressing cassettes with different SIVsm inserts, have potential utility as an effective antigen display system for immunogen testing in vivo and for initial epitope assessments in vitro. Previous mouse model studies demonstrated immunization with r-GV expressing selected exogenous sequences elicited a prolonged immune response. Here we tested segments from three SIVsm genes (tat, rev, and nef each surface displayed by r-GV. As with HIV, for SIVsm the proteins encoded by tat, rev and nef respectively serve critical and diverse functions: effects on efficient viral RNA polymerase II transcription, regulation of viral gene expression and effects on specific signaling functions through the assembly of multiprotein complexes. Humoral responses to r-GVTat, Rev or Nef1 elicited in vivo, associated changes in selected cell cytokine production following r-GV internalization, and the capacity of J774A.1 macrophage cells to degrade these internalized display/delivery particles in vitro were examined. Results The in vivo studies involving r-GV immunizations and in vitro studies of r-GV uptake by J774A.1 macrophages demonstrated: (i tests for antibody isotypes in immunized mice sera showed activation and re-stimulation of memory B cells, (ii during long term immune response to the epitopes, primarily the IgG1 isotype was produced, (iii in vitro, macrophage degradation of r-GV containing different SIVsm inserts occurred over a period of days resulting in an inherent slow breakdown and degradation of the SIVsm peptide inserts, (iv vesicle specific GvpC, a larger protein, degraded more slowly than the recombinant peptide inserts and (v in vitro uptake and degradation of the r-GV populations tested was associated with SIVsm insert specific patterns for cytokines IL-10, IL-12 and IL-18. Conclusions Together these findings provide new information underscoring r-GV potential

    Elsam Engineering AS has approved the implementation of a project concerning the registration of fish communities in Horns Rev Offshore Wind Farm with use of hydroacoustic methods. In a joint effort, Bio/consult as, Carl Bro as and SIMRAD AS have monitored the fish communities at Horns Rev Offshore Wind Farm using a new hydroacoustic methodology. The new hydroacoustic technique combines the use of scientific sonar acoustics with GPS to determine the density, diversity and location of fish. The objectives of this project were to test the possibility of using hydroacoustic techniques as alternative methods to traditional techniques to assess the fish assemblage inhabiting offshore wind farms and to investigate the possible effect from the wind farm and hard bottom substrates (turbine foundations) on fish abundance. The field study was carried out October 9-10, 2004 and consisted of four horizontal hydroacoustic survey transects each covering impact and reference areas. Transects were surveyed in order to achieve identical impact and reference transect pairs concerning environment, topography and time correspondence. The hydroacoustic equipment consisted of a SIMRAD EK60/EY60 echo sounder with a split-beam transducer (Simrad ES 120-4x10) mounted on a pan and tilt unit, a transceiver, a laptop extended with a GPS-receiver and additional large external hard discs. The raw data files from EK60 were converted to echogram files suitable for the post processing application, Sonar5-Pro. The Sonar5-Pro software makes it possible to filter out echo detections from the surface and the bottom, as well as perform cross filter detection. The validity of the results using the hydroacoustic method is high due to the cross filtering and single target tracking technique. From the hydroacoustic results, no or very little effect from the wind farm or from hard bottom substrates was found on the fish densities at Horns Rev Wind Farm at the time of the survey. The execution of the field

  15. Development of underground-mine cost-estimating equations. [Dependence of initial capital cost, deferred capital cost and annual operating cost on region, annual mine output and seam depth

    Energy Technology Data Exchange (ETDEWEB)

    1981-03-06

    Table 3.3 summarizes the initial capital, deferred capital, and operating costs (in millions of 1980 dollars) for the four regionally-based underground model mines. The initial capital is divided into two components, fixed and variable. The fixed component is just the investment cost for surface facilities, which is assumed to be independent of mine size. The rest of the initial capital cost is associated with production (primarily face-related) and is assumed to vary linearly with mine size (i.e., annual output). There exists a concern that deferred capital costs will change due to entry mode. However, the installations concerned primarily with this point are depreciated off over the mine life and are not targeted for replacement. Therefore, deferred capital costs will not change significantly with entry mode changes or seam depth. In conclusion, it is our feeling that, within the resources of this project, development of cost adjustment factors relating productivity to various supply regions and seam heights is not practical. Assuming that productivity and, therefore, cost is independent of seam height will introduce errors into the system; however, their extent should be minimized by the incorporation of multiple model mines into the RAMC. Lastly, the relationship presented in this memorandum for depth of cover should be used in the RAMC.

    The principal objectives of this work were to investigate the effects of processing simulated Hanford HLW at the estimated maximum concentrations of nitrates and oxalates and to identify strategies to mitigate any processing issues resulting from high concentrations of nitrates and oxalates. This report provides results for a series of tests that were performed on the DM10 melter system with simulated C-106/AY-102 HLW. The tests employed simulated HLW feeds containing variable amounts of nitrates and waste organic compounds corresponding to maximum concentrations proj ected for Hanford HLW streams in order to determine their effects on glass production rate, processing characteristics, glass redox conditions, melt pool foaming, and the tendency to form secondary phases. Such melter tests provide information on key process factors such as feed processing behavior, dynamic effects during processing, processing rates, off-gas amounts and compositions, foaming control, etc., that cannot be reliably obtained from crucible melts.

    The Low Activity Waste (LAW) tanks that are scheduled to provide the Hanford Tank Waste Treatment and Immobilization Plant (WTP) with waste feeds contain significant amounts of sulfate. The sulfate content in the LAW feeds is sufficiently high that a separate molten sulfate salt phase may form on top of the glass melt during the vitrification process unless suitable glass formulations are employed and sulfate levels are controlled. Since the formation of the salt phase is undesirable from many perspectives, mitigation approaches had to be developed. Considerable progress has been made and reported by the Vitreous State Laboratory (VSL) in enhancing sulfate incorporation into LAW glass melts and developing strategies to manage and mitigate the risks associated with high-sulfate feeds.

    Rex of human T-cell leukemia virus type I (HTLV-I) and Rev of human immunodeficiency virus 1 (HIV-1) are post-transcriptional regulators of viral gene expression. By means of affinity chromatography, we purified an 18-kDa cellular protein that bound to the conserved leucine-motif/activation domain of HTLV-I Rex or HIV-1 Rev. The protein that was purified through a Rev-affinity column was found to bind to Rex immunoprecipitated with anti-Rex IgG from an HTLV-I-producing cell line. We analyzed the purified approximately 18-kDa protein biochemically and identified it as prothymosin alpha. The binding activity of prothymosin alpha to Rev or Rex was completely abolished when the epsilon-amino groups of its lysine residues were chemically modified by N-succinimidyl-3-(4-hydroxy-3,5-diodo- phenyl)propionate. The functional relationship between the nuclear protein prothymosin alpha and Rex-Rev is discussed.

    In 2001, the former Ministry of the Environment and Energy granted Elsam A/S and Eltra A.m.b.A. approval to establish a wind farm capable of producing 160 MW of electric power, at Horns Rev, west of Blaevandshuk at the west coast of Jutland. According to the conditions of the approval, Elsam and Eltra were required to monitor the environmental effects of the wind farm by performing monitoring before, during and after construction of the wind farm. The environmental monitoring programme is financed through Public Service Obligation (PSO). Analogue to the Horns Rev wind farm another offshore demonstrational wind farm was established in the Baltic sea south of Lolland by Energi E2 the Nysted 165 MW offshore wind farm. To coordinate the environmental monitoring at the two demonstration wind farms at Nysted and Horns Rev within the framework of the approved budget, the Environmental Group of Danish Offshore Wind Farm Demonstration Projects was set up. The group consists of representatives from the Danish Forest and Nature Agency, the Danish Energy Authority, Elsam and Energi E2. The Environmental Group initiates, monitors and evaluates the environmental programmes continuously with respect to possible improvements and intensifications to ensure that the design of the individual programmes is optimal. After evaluation, the monitoring programmes are proposed by the Environmental Group and carried out after final approval by the Danish Energy Authority. The Environmental Group considers if there is reason to adjust the issues and priorities of the programmes based on previous experience or other inputs eg from the international expert panel, IAPEME (International Advisory Panel of Experts on Marine Ecology). IAPEME evaluates the environmental monitoring programmes and makes valuable suggestions and recommendations to the Environmental Group. The programmes have concentrated on the monitoring of possible impacts before, during and after construction to investigate and

    Plans for the treatment of high level waste (HL W) at the Hanford Tank Waste Treatment and Immobilization Plant (WTP) are based upon the inventory of the tank wastes, the anticipated performance of the pretreatment processes, and current understanding of the capability of the borosilicate glass waste form [I]. The WTP HLW melter design, unlike earlier DOE melter designs, incorporates an active glass bubbler system. The bubblers create active glass pool convection and thereby improve heat and mass transfer and increase glass melting rates. The WTP HLW melter has a glass surface area of 3.75 m{sup 2} and depth of ~ 1.1 m. The two melters in the HLW facility together are designed to produce up to 7.5 MT of glass per day at 100% availability. Further increases in HL W waste processing rates can potentially be achieved by increasing the melter operating temperature above 1150°C and by increasing the waste loading in the glass product. Increasing the waste loading also has the added benefit of decreasing the number of canisters for storage.

    The U.S. Department of Energy (DOE), Office of River Protection (ORP), has contracted with Bechtel National, Inc. (BNI) to design, construct, and commission the Hanford Tank Waste Treatment and Immobilization Plant (WTP) at the Hanford Site (DOE 2000). This plant is designed to operate for 40 years and treat roughly 50 million gallons of mixed hazardous high-level waste (HLW) stored in 177 underground tanks at the Hanford Site. The process involves separating the hight-level and low-activity waste (LAW) fractions through filtration, leaching, Cs ion exchange, and precipitation. Each fraction will be separately vitrified into borosilicate waste glass. This report documents the initial algorithm for use by Hanford WTP in batching LAW and glass-forming chemicals (GFCs) in the LAW melter feed preparation vessel (MFPV). Algorithm inputs include the chemical analyses of the pretreated LAW in the concentrate receipt vessel (CRV), the volume of the MFPV heel, and the compositions of individual GFCs. In addition to these inputs, uncertainties in the LAW composition and processing parameters are included in the algorithm.

    The Melt Attack and Coolability Experiments (MACE) program at Argonne National Laboratory addressed the issue of the ability of water to cool and thermally stabilize a molten core-concrete interaction when the reactants are flooded from above. These tests provided data regarding the nature of corium interactions with concrete, the heat transfer rates from the melt to the overlying water pool, and the role of noncondensable gases in the mixing processes that contribute to melt quenching. The Melt Coolability and Concrete Interaction (MCCI) program is pursuing separate effect tests to examine the viability of the melt coolability mechanisms identified as part of the MACE program. These mechanisms include bulk cooling, water ingression, volcanic eruptions, and crust breach. At the second PRG meeting held at ANL on 22-23 October 2002, a preliminary design1 for a separate effects test to investigate the melt eruption cooling mechanism was presented for PRG review. At this meeting, NUPEC made several recommendations on the experiment approach aimed at optimizing the chances of achieving a floating crust boundary condition in this test. The principal recommendation was to incorporate a mortar sidewall liner into the test design, since data from the COTELS experiment program indicates that corium does not form a strong mechanical bond with this material. Other recommendations included: (i) reduction of the electrode elevation to well below the melt upper surface elevation (since the crust may bond to these solid surfaces), and (ii) favorably taper the mortar liner to facilitate crust detachment and relocation during the experiment. Finally, as a precursor to implementing these modifications, the PRG recommended the development of a design for a small-scale scoping test intended to verify the ability of the mortar liner to preclude formation of an anchored bridge crust under core-concrete interaction conditions. This revised Melt Eruption Test (MET) plan is intended to

    Vaccination with the live attenuated Brucella melitensis Rev 1 vaccine is used to control ovine brucellosis caused by Brucella ovis in sheep. The objective of this study was to identify possible correlates of protective response to B. ovis infection through the characterization by microarray hybridization and real-time RT-PCR of inflammatory and immune response genes differentially expressed in rams previously immunized with B. melitensis Rev 1 and experimentally challenged with B. ovis. Gene expression profiles were compared before and after challenge with B. ovis between rams protected and those vaccinated but found infected after challenge. The TLR10, Bak and ANXI genes were expressed at higher levels in vaccinated and protected rams. These genes provide possible correlates of protective response to B. ovis infection in rams immunized with the B. melitensis Rev 1 vaccine.

    Resistance to temozolomide poses a major clinical challenge in glioblastoma multiforme treatment, and the mechanisms underlying the development of temozolomide resistance remain poorly understood. Enhanced DNA repair and mutagenesis can allow tumour cells to survive, contributing to resistance and tumour recurrence. Here, using recurrent temozolomide-refractory glioblastoma specimens, temozolomide-resistant cells, and resistant-xenograft models, we report that loss of miR-29c via c-Myc drives the acquisition of temozolomide resistance through enhancement of REV3L-mediated DNA repair and mutagenesis in glioblastoma. Importantly, disruption of c-Myc/miR-29c/REV3L signalling may have dual anticancer effects, sensitizing the resistant tumours to therapy as well as preventing the emergence of acquired temozolomide resistance. Our findings suggest a rationale for targeting the c-Myc/miR-29c/REV3L signalling pathway as a promising therapeutic approach for glioblastoma, even in recurrent, treatment-refractory settings.

    The purpose of this report is to present analogue studies and literature reviews designed to provide qualitative and quantitative information to test and provide added confidence in process models abstracted for performance assessment (PA) and model predictions pertinent to PA. This report provides updates to studies presented in the Yucca Mountain Site Description (CRWMS M&O 2000 [151945], Section 13) and new examples gleaned from the literature, along with results of quantitative studies conducted specifically for the Yucca Mountain Site Characterization Project (YMP). The intent of the natural analogue studies was to collect corroborative evidence from analogues to demonstrate additional understanding of processes expected to occur during postclosure at a potential Yucca Mountain repository. The report focuses on key processes by providing observations and analyses of natural and anthropogenic (human-induced) systems to improve understanding and confidence in the operation of these processes under conditions similar to those that could occur in a nuclear waste repository. The process models include those that represent both engineered and natural barrier processes. A second purpose of this report is to document the various applications of natural analogues to geologic repository programs, focusing primarily on the way analogues have been used by the YMP. This report is limited to providing support for PA in a confirmatory manner and to providing corroborative inputs for process modeling activities. Section 1.7 discusses additional limitations of this report. Key topics for this report are analogues to emplacement drift degradation, waste form degradation, waste package degradation, degradation of other materials proposed for the engineered barrier, seepage into drifts, radionuclide flow and transport in the unsaturated zone (UZ), analogues to coupled thermal-hydrologic-mechanical-chemical processes, saturated zone (SZ) transport, impact of radionuclide release

    Full Text Available Pinnacle Advisory Group provides an update of lodging industry performance in New England, with a focus on Boston for 2013. While the New England region was behind the nation, the story varied from state to state. Only Massachusetts and Vermont achieved RevPAR performance better than the national average. The region as a whole is improving its performance, with RevPAR lagging only 0.2 percent, compared to 1.2 percent the year before. The outlook for the future remains positive as limited supply growth coupled with moderate growth in demand will result in higher occupancy levels and higher revenues.

    This annual report presents the work related to the sociological part of the socio-economic project on the local communities' reception of the Horns Rev Offshore Wind Farm, west of Blaavands Huk in Jutland, and the Nysted Offshore Wind Farm, south of Lolland. The project is part of the monitoring programme in connection with the construction of the offshore wind farms. Unlike projects, which examine the impact of the wind farms on nature, the socio-economic project did not start until 2003. The socio-economic project examines the effects on the local communities. Among other things the environmental-economic part of the project examines the preferences of the population in relation to location of the wind farm and the willingness to pay for increasing the distance between the wind farms and the coast. The sociological survey is qualitative. The survey is divided into three phases, as the aim is to investigate the public community's attitude towards the erection of an offshore wind farm before and after the construction of the wind farm. This aim is based on the assumption that attitudes may change once the wind farm is erected and the population has experienced the visibility of the wind farm, etc. The division into phases is as follows: 1) Phase 1 treats the conditions as they were before the erection of Nysted Offshore Wind Farm. 2) Phase 2 is an investigation of the development in attitudes towards Horns Rev Offshore Wind Farm a year after erection. 3) Phase 3 comprises a follow-up investigation of the local area at Nysted Offshore Wind Farm. This annual report treats phases 1 and 2. Phase 1 was carried out in April-August 2003, and the interviews at Nysted were thus made during the erection of the first offshore wind turbines. Phase 2 was carried out in September-November 2003. The follow-up investigation of the conditions in the local area around Nysted offshore wind farm is to be carried out in August-December 2004. The results of the investigations

    In February 1998, the Ministry of the Environment gave Elsam A/S and Eltra A.m.b.a. approval to erect a wind farm, capable of producing 160 MW of electric power, at Horns Rev, west of Blaevandshuk off the west coast of Jutland. Construction activities at Horns Rev started in September 2001 and were finished in summer 2002. The entire project has been organised as a demonstration project to assess the technical, economic and environmental constraints on the future development of electric power production in Danish offshore environments. Within the framework of the environmental programme, bird investigations have been carried out in relation to the risk of collision between birds and wind turbines since 2002. To provide the latest update on the results from the bird investigations, this note presents results compiled during spring 2004 and deals with a preliminary analysis of effects on birds present at Horns Rev during commercial operation of the Horns Rev wind farm. Due to the remoteness of the area it has not been possible to obtain base-line investigation of bird occurrence and behaviour at the wind farm site. (au)

    Rev is an essential HIV-1 regulatory protein which binds to the Rev responsive element (RRE) present within the env gene of HIV-1 RNA genome. This binding facilitates the transport of the RNA to the cytoplasm, which in turn triggers the switch between viral latency and active viral replication. Essential components of this complex have been localized to a minimal arginine rich Rev peptide and stem IIB region of RRE. A synthetic peptide known as RSG-1.2 binds with high binding affinity and specificity to the RRE-IIB than the Rev peptide, however the thermodynamic basis of this specificity has not yet been addressed. The present study aims to probe the thermodynamic origin of this specificity of RSG-1.2 over Rev Peptide for RRE-IIB. The temperature dependent melting studies show that RSG-1.2 binding stabilizes the RRE structure significantly (ΔT(m) = 4.3°C), in contrast to Rev binding. Interestingly the thermodynamic signatures of the binding have also been found to be different for both the peptides. At pH 7.5, RSG-1.2 binds RRE-IIB with a K(a) = 16.2±0.6×10(7) M(-1) where enthalpic change ΔH = -13.9±0.1 kcal/mol is the main driving force with limited unfavorable contribution from entropic change TΔS = -2.8±0.1 kcal/mol. A large part of ΔH may be due to specific stacking between U72 and Arg15. In contrast binding of Rev (K(a) = 3.1±0.4×10(7) M(-1)) is driven mainly by entropy (ΔH = 0 kcal/mol and TΔS = 10.2±0.2 kcal/mol) which arises from major conformational changes in the RNA upon binding.

  4. Translational regulation of HIV-1 replication by HIV-1 Rev cellular cofactors Sam68, eIF5A, hRIP, and DDX3.

    Nuclear export and translation of HIV-1 RNA are two important posttranscriptional events for HIV-1 gene expression and replication. HIV-1 Rev functions to export unspliced and incompletely spliced HIV-1 RNA from the nucleus to the cytoplasm; it requires interaction with several cellular cofactors such as Sam68, eIF5A, hRIP, and DDX3. Meanwhile, some studies have also implicated Rev and some of its cofactors such as Sam68 in HIV-1 RNA translation. Thus, in this study, we aimed to characterize the potential function of all these four Rev cofactors in HIV-1 RNA translation. Ectopic expression, siRNA knockdown, and trans-complementation assays confirmed that all these cofactors were very important for HIV-1 gene expression and production through Rev and, accordingly, Rev-dependent reporter gene expression. Importantly, these studies revealed for the first time that each of these cofactors also regulated Rev-independent reporter gene expression. To directly determine the roles of these cofactors in HIV-1 RNA translation, we designed and synthesized a full-length capped HIV-1 RNA in vitro, transfected it into cells to bypass the RNA nuclear export step, and determined HIV-1 Gag expression from the cytoplasmic RNA in the cells that had ectopically expressed or siRNA knocked down cofactors. Gag expression was found to closely correlate with the expression levels of all these cofactors. Furthermore, we took advantage of a HIV-1 internal ribosomal entry site (IRES)-based bicistronic reporter gene assay and determined the effects of these cofactors on cap-independent IRES-mediated HIV-1 translation. The results showed that DDX3, eIF5A, and hRIP enhanced HIV-1 IRES-mediated translation, whereas Sam68 did not. Taken together, these results show that HIV-1 Rev cofactors Sam68, eIF5A, hRIP, and DDX3 also function in the translation of HIV-1 RNA and suggest that the regulatory mechanisms of HIV-1 RNA translation are likely different among these cofactors.

    Full Text Available BACKGROUND: Measures to prevent chronic calcineurin inhibitor (CNI toxicity have included limiting exposure by switching to sirolimus (SIR. SIR may favorably influence T regulator cell (T(reg population. This randomized controlled trial compares the effect of switching from CNI to SIR on glomerular filtration rate (GFR and T(reg frequency. METHODS: In this prospective open label randomized trial, primary living donor kidney transplant recipients on CNI-based immunosuppression were randomized to continue CNI or switched to sirolimus 2 months after surgery; 29 were randomized to receive CNI and 31 to SIR. All patients received mycophenolate mofetil and steroids. The main outcome parameter was estimated GFR (eGFR at 180 days. T(reg population was estimated by flowcytometry. RESULTS: Baseline characteristics in the two groups were similar. Forty-eight patients completed the trial. At six months, patients in the SIR group had significantly higher eGFR as compared to those in the CNI group (88.94 ± 11.78 vs 80.59 ± 16.51 mL/min, p = 0.038. Patients on SIR had a 12 mL/min gain of eGFR of at the end of six months. Patients in the SIR group showed significant increase in T(reg population at 30 days, which persisted till day 180. There was no difference in the adverse events in terms of number of acute rejection episodes, death, infections, proteinuria, lipid profile, blood pressure control and hematological parameters between the two groups. Four patients taking SIR developed enthesitis. No patient left the study or switched treatment because of adverse event. CONCLUSIONS: A deferred pre-emptive switch over from CNI to SIR safely improves renal function and T(reg population at 6 months in living donor kidney transplant recipients.

    An adverse intrauterine environment leads to permanent physiological changes including vascular tone regulation, potentially influencing the risk for adult vascular diseases. We therefore aimed to monitor responsive NOS3 expression in human umbilical artery endothelial cells (HUAEC) and to study the underlying epigenetic signatures involved in its regulation. NOS3 and STAT3 mRNA levels were elevated in HUAEC of patients who suffered from placental insufficiency. 5-hydroxymethylcytosine, H3K9ac and Histone 2A (H2A).Zac at the NOS3 transcription start site directly correlated with NOS3 mRNA levels. Concomitantly, we observed entangled histone acetylation patterns and NOS3 response upon hypoxic conditions in vitro. Knock-down of either NOS3 or STAT3 by RNAi provided evidence for a functional NOS3/STAT3 relationship. Moreover, we recognized massive turnover of Stat3 at a discrete binding site in the NOS3 promoter. Interestingly, induced hyperacetylation resulted in short-termed increase of NOS3 mRNA followed by deferred decrease indicating that NOS3 expression could become self-attenuated by co-expressed intronic 27 nt-ncRNA. Reporter assay results and phylogenetic analyses enabled us to propose a novel model for STAT3-3'-UTR targeting by this 27-nt-ncRNA. An adverse intrauterine environment leads to adaptive changes of NOS3 expression. Apparently, a rapid NOS3 self-limiting response upon ectopic triggers co-exists with longer termed expression changes in response to placental insufficiency involving differential epigenetic signatures. Their persistence might contribute to impaired vascular endothelial response and consequently increase the risk of cardiovascular disease later in life.

    Laboratory exercise is helpful for medical students to understand the basic principles of molecular biology and to learn about the practical applications of molecular biology. We have designed a lab course on molecular biology about the determination of single nucleotide polymorphism (SNP) in human REV3 gene, the product of which is a subunit of DNA polymerase ζ and SNPs in this gene are associated with altered susceptibility to cancer. This newly designed experiment is composed of three parts, including genomic DNA extraction, gene amplification by PCR, and genotyping by RFLP. By combining these activities, the students are not only able to learn a series of biotechniques in molecular biology, but also acquire the ability to link the learned knowledge with practical applications. This comprehensive experiment will help the medical students improve the conceptual understanding of SNP and the technical understanding of SNP detection. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):299-304, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    Cross-sectional serological surveys of 13,006 small ruminants were conducted in 2003 to establish baseline levels of seropositivity to brucellosis and of 12,102 again in 2009 to evaluate the efficacy of controls based on biannual conjunctival vaccination with Rev 1. Seroprevalence dropped by 80 per cent in five years in eight pilot programme districts where vaccination was generally well implemented, and the prevalence of households with evidence of infection in their animals dropped from 25.1 to 7.5 per cent. Seroprevalence was reduced by 40 per cent in 10 districts where vaccination was intermittent with low coverage during some seasons. There were no changes in 19 districts where no vaccinations were carried out. Sheep vaccinated one or more times were found to be 2.5 times more likely to be serotest positive than were non-vaccinated sheep, whereas vaccinated goats were 6.4 times more likely to be serotest positive than non-vaccinated goats.

    The authors of the above paper call into question recent evidence on the properties of self-interstitials, I, in Ge [Cowern et al., Phys. Rev. Lett. 110, 155501 (2013)]. We show that this judgment stems from invalid model assumptions during analysis of data on B marker-layer diffusion during proton irradiation, and that a corrected analysis fully supports the reported evidence. As previously stated, I-mediated self-diffusion in Ge exhibits two distinct regimes of temperature, T: high-T, dominated by amorphous-like mono-interstitial clusters—i-morphs—with self-diffusion entropy ≈30 k, and low-T, where transport is dominated by simple self-interstitials. In a transitional range centered on 475 °C both mechanisms contribute. The experimental I migration energy of 1.84 ± 0.26 eV reported by the Münster group based on measurements of self-diffusion during irradiation at 550 °C < T < 680 °C further establishes our proposed i-morph mechanism.

This benthic survey includes sampling in a proposed reference area for the fish surveys north east of the wind farm. This report presents the data of the baseline environmental survey of the seabed in the wind farm site and in the proposed reference site and a brief description of the weather conditions at the time of sampling.

    The resin infusion process (RIP) has developed as a low cost method for manufacturing large fibre reinforced plastic parts. However, the process still presents some challenges to industry with regards to reliability and repeatability, resulting in expensive and inefficient trial and error development. In this paper, we show the implementation of 2D numerical models for the RIP using the open source simulator DuMu{sup X}. The idea of this study is to present a model which accounts for the interfacial forces coming from the capillary pressure on the so-called representative elementary volume (REV) scale. The model is described in detail and three different test cases — a constant and a tensorial permeability as well as a preform/Balsa domain — are investigated. The results show that the developed model is very applicable for the RIP for manufacturing of composite parts. The idea behind this study is to test the developed model for later use in a real application, in which the preform medium has numerous layers with different material properties.

    Matter is made up of atoms: the atomic nucleus, protons and neutrons, and electrons. There are several other particles besides protons, neutrons, and electrons, and it has become customary to refer to these as elementary or fundamental particles. The particles make up the fine structure of matter with which this booklet deals. This field of science is often referred to as particle physics or high-energy physics because of the fact that particle beams of extremely high energy are needed in most of its pertinent experiments.

    Our whole industrial civilization depends upon cheap energy streaking out in all directions and under fingertip controls—and that would be very difficult without electric current. It would take enormous ingenuity to find substitutes. If all electricity were shut off, then all electronic devices would be dead. Electric lights would darken. Aluminum would become a rare metal. All factories would have to develop power sources on the spot and would have to switch to primitive, mechanical controls. Every house and every farm would have to give up items we have come to take for granted—not only electric lights, but electric irons, electric toasters, electric water pumps, electric control of furnaces, and so on.

  16. TRACKED VEHICLE Rev 75

    2007-05-08

    Revision 75 of the Tracked Vehicle software is a soft real-time simulation of a differentially steered, tracked mobile robot, which, because of the track flippers, resembles the iRobot PackBot (http://www.irobot.com/). Open source libraries are used for the physics engine (http://www.ode.org/), the display and user interface (http://www.mathies.com/cpw/), and the program command line and configuration file parameters (http://www.boost.org/). The simulation can be controlled by a USB joystick or the keyboard. The configuration file contains demonstration model parameters of no particular vehicle. This simulation can be used as a starting point for those doing tracked vehicle simulations. This simulation software is essentially a research tool which can be modified and adapted for certain types of tracked vehicle research. An open source license allows an individual researchers to tailor the code to their specific research needs.

    1973-01-01

    Projected energy requirements for the future suggest that we must employ atomic energy to generate electric power or face depletion of our fossil-fuel resources—coal, oil, and gas. In short, both conservation and economic considerations will require us to use nuclear energy to generate the electricity that supports our civilization. Until we reach the time when nuclear power plants are as common as fossil-fueled or hydroelectric plants, many people will wonder how the nuclear plants work, how much they cost, where they are located, and what kinds of reactors they use. The purpose of this booklet is to answer these questions. In doing so, it will consider only central station plants, which are those that provide electric power for established utility systems.

  20. Horns Rev offshore wind farm. Introducing hard bottom substrate sea bottom and marine biology. Status report 2001

    2002-08-15

    A baseline description of the benthos was carried out in spring and autumn 2001 prior to the construction of an offshore wind farm at Horns Rev, situated approximately 15 km off Blaevands Huk, which is Denmark's most westerly point. The surveys have been conducted as part of an environmental monitoring programme for the introduction of hard bottom substrates in the North Sea. The establishment of a monitoring programme is required according to some environmental guidelines set up by the Danish Energy Agency for offshore wind farms. Because no environmental criteria existed for benthic communities in connection with the construction activities, no power analysis was made prior to the design of the monitoring programme. The monitoring programme established for the benthic infauna is thus somewhat limited and only major changes in the community structure are expected to be detectable. The baseline description for the benthic infauna can also be used for comparison of the stomach contents of fish in a comparative programme. A newly defined reference area may be introduced for the fish programme why sampling in this area was carried out in the autumn 2001. Samples were recovered at a total of 18 stations at 6 wind turbine locations in the wind farm area in June 2001 and at a total of 9 stations at 3 wind turbine locations in September 2001. In September additional sampling was carried out at 5 stations in a designated reference area. At the wind turbine locations sampling was carried out at 3 stations located 5, 25 and 100 m from the edge of the planned scour protection. Samples were analysed for sediment characteristics and for benthic infauna. Only the benthos relating to the macrofauna was investigated during the surveys. (au)

  1. Making mission possible. A response to Rev. Richard A. McCormick's article on the preservation of Catholic hospitals.

    Science.gov (United States)

    O'Rourke, K D

    1995-01-01

    In "The Catholic Hospital Today: Mission Impossible?" (Origins, March 16, 1995, pp. 648-653), Rev. Richard A. McCormick, SJ, STD, questions whether Catholic hospitals can continue their missions in a society with so many factors and influences that seem to oppose efforts to perpetuate the healing ministry of Christ. As Fr. McCormick states, the matrix of good medicine is centered on the good of the individual. But too often, the patient has been considered an individual isolated from others. The rights of families, people who belong to the same insurance program, and the society funding much of healthcare must also be considered. Fr. McCormick points out that an obstacle to the healing mission arises because healthcare is often treated as a business instead of a service. If not-for-profit healthcare facilities come to exist for the well-being of the shareholders, as do for-profit healthcare facilities, then a perversion of values results. This should lead us to renounce for-profit healthcare and the behavior that some Catholic health organizations have borrowed from the for-profit sector. In addition, Fr. McCormick calls attention to our society's denial of death and tendency to call on medicine to cure personal, social, or economic problems. This denial-of-death phenomenon helps us realize the need for the mission of Catholic hospitals. Continuing the mission of Catholic hospitals will require the attention of all involved in them-physicians, trustees, nurses, administrators, and ancillary personnel. These healthcare providers must not be distracted from the mission by joint ventures and economic issues.

  2. Base-line investigations of birds in relation to an offshore wind farm at Horns Rev: results and conclusions 2000/2001

    This report presents the combined results of two years of base-line investigations of birds performed during August 1999 - April 2001 in relation to the proposed construction of an offshore wind farm at Horns Rev in the Danish part of the North Sea ca 14 km southwest of Blaevandshuk. Based on the distribution of the most abundant bird species recorded during 13 aerial surveys, there were no indications that the wind farm area was of any particular importance to the birds' exploitation of the Horns Rev area. Fish-eating species like divers, gannet, terns, auks and gulls generally showed scattered and variable distributions, occurring in the areas north and south of Horns Rev, and with low numbers occurring on the reef proper and within the planned wind farm area. The distribution of benthic foraging species, eider and common scoter, showed that they mainly exploited the coastal parts of the area off Blaevandshuk and Skallingen, although the common scoter was found in relatively high numbers on the southeast slopes of Horns Rev and within the wind farm area in the April 2001 survey. Preference analyses of bird exploitation of the Horns Rev area showed that if the birds completely avoid the wind farm area after erection of the wind turbines, this will affects less than 1% of the different species, except divers of which 1.65% will be affected. If the birds avoid the wind farm area and an adjacent 4 km zone (worst case scenario), it is estimated to affect 11% of the common scoter, 10% of the gannet, 7-9% of the divers, alcids and velvet scoter and 0-6% of the remaining species. The seasonal occurrence of the recorded species was fully comparable to the seasonal occurrence of these species recorded at Blaevandshuk since 1963. Year-to-year variation in abundance between the seasons August 1999 - April 2000 and August 2000 - April 2001 was mainly found in species that migrate through the Horns Rev area (terns, gannet, kittiwake), and with less pronounced variation in

  4. RevSex duplication-induced and sex-related differences in the SOX9 regulatory region chromatin landscape in human fibroblasts.

    It was recently shown that duplications of the RevSex element, located 0.5 Mb upstream of SOX9, cause XX-disorder of sex development (DSD), and that deletions cause XY-DSD. To explore how a 148 kb RevSex duplication could have turned on gonadal SOX9 expression in the absence of SRY in an XX-male, we examined the chromatin landscape in primary skin fibroblast cultures from the index, his RevSex duplication-carrier father and six controls. The ENCODE project supports the notion that chromatin state maps show overlap between different cell types, i.e., that our study of fibroblasts could be of biological relevance. We examined the SOX9 regulatory region by high-resolution ChIP-on-chip experiments (a kind of "chromatin-CGH") and DNA methylation investigations. The RevSex duplication was associated with chromatin changes predicting better accessibility of the SRY-responsive TESCO enhancer region 14-15 kb upstream of SOX9. Four kb downstream of the TESCO evolutionary conserved region, a peak of the enhancer/promoter-associated H3K4me3 mark was found together with a major dip of the repressive H3K9me3 chromatin mark. Similar differences were also found when three control males were compared with three control females. A marked male/female difference was a more open chromatin signature in males starting ~400 kb upstream of SOX9 and increasing toward the SOX9 promoter. In the RevSex duplication-carrier father, two positions of DNA hypomethylation were also found, one corresponding to the H3K4me3 peak mentioned above. Our results suggest that the RevSex duplication could operate by inducing long-range epigenetic changes. Furthermore, the differences in chromatin state maps between males and females suggest that the Y chromosome or X chromosome dosage may affect chromatin conformation, i.e., that sex-dependent gene regulation may take place by chromatin modification.

    Full Text Available Three groups of Shami goats were randomly vaccinated with Brucevac (Rev. 1 vaccine. Group 1 was vaccinated subcutaneously with a full dose (1.54 x 109 organisms. Group 2 was vaccinated conjunctively with one eye drop (5.2 x 108 organisms, while Group 3 was injected subcutaneously with a reduced dose (7.1 x 105 organisms of vaccine. Blood samples were collected before vaccination, two, four, eight, 15 and 24 weeks post vaccination. All samples were tested through CFT, ELISA, SAT and Rose Bengal plate test. All serological tests used detected a higher percentage of vaccinated female kids with a full dose than they did in other groups vaccinated with a reduced dose or with a conjunctival dose of Rev.1 vaccine. The overall results suggested that 100% of animals vaccinated with a conjunctival dose became positive to CFT at two, four, eight and 15 weeks post vaccination, and then the percentage of seropositive animals declined and became 20% at 24 weeks post inoculation. The conjunctival route of vaccination significantly reduced the intensity and duration of the post vaccination serological response, which makes the use of this vaccine compatible with brucellosis programmes, even when these are based on a test-and–slaughter policy. The overall results showed that Shami goats responded to Rev.1 vaccine in the expected way. The majority of animals were seropositive to the CFT by two weeks after vaccination with higher numbers of seropositive animals in the kids group vaccinated with a full dose of Rev.1 vaccine.

    2003-04-15

    This annual report, which is a baseline and/or an evaluation of the effects of construction phase, is based on extracts from our consultants' annual reports. These annual reports are individual reports, in which surveys have been made during the year 2002 and reported in the beginning of 2003. Detailed information on methods, programmes and conclusions can be found in these reports. In general it should be noted that apparently the construction phase has not had any unintended effects on the parameters surveyed. Therefore we can also conclude that the protective measures established by Elsam, especially scaring devices/ramp-ups for marine mammals, have had the intended effect. Especially interesting parameters that should be mentioned are: Birds: The seagull species 'Herring Gulls' was found to be attracted by the wind farm during the construction period. The number of Divers has decreased, however statistically this decrease is very small as very few Divers have been observed under the baseline. Porpoises: Porpoises generally stayed away from the construction area during pile driving. This effect was intended and scaring devices were deployed in order to ensure that the animals' hearing was not permanently damaged. Seals: The purpose of the programme has not been to show statistically significant effects during the construction phase. The purpose was to get an idea of their behaviour during the construction phase within the wind farm as well as on the reef. It has been concluded that Horns Rev is not used as a foraging area as much as expected. It is used as transit area for bigger foraging sites in the North Sea. Sand eels and Spisula: A baseline survey of sand eels within the wind farm area has been made. It is shown that sand eels are found in the wind farm area. Spisula have been found in the wind farm area but not in the amount expected. Hard substrate habitat: Baseline surveys on fish have been made during the spring of 2002. The

    Full Text Available Alfes, Griffin, Ono, and Rolen have shown that the harmonic Maass forms arising from Weierstrass ζ-functions associated to modular elliptic curves “encode” the vanishing and nonvanishing for central values and derivatives of twisted Hasse-Weil L-functions for elliptic curves. Previously, Martin and Ono proved that there are exactly five weight 2 newforms with complex multiplication that are eta-quotients. In this paper, we construct a canonical harmonic Maass form for these five curves with complex multiplication. The holomorphic part of this harmonic Maass form arises from the Weierstrass ζ-function and is referred to as the Weierstrass mock modular form. We prove that the Weierstrass mock modular form for these five curves is itself an eta-quotient or a twist of one. Using this construction, we also obtain p-adic formulas for the corresponding weight 2 newform using Atkin’s U-operator.

  4. High Affinity Heme Binding to a Heme Regulatory Motif on the Nuclear Receptor Rev-erbβ Leads to Its Degradation and Indirectly Regulates Its Interaction with Nuclear Receptor Corepressor.

    Rev-erbα and Rev-erbβ are heme-binding nuclear receptors (NR) that repress the transcription of genes involved in regulating metabolism, inflammation, and the circadian clock. Previous gene expression and co-immunoprecipitation studies led to a model in which heme binding to Rev-erbα recruits nuclear receptor corepressor 1 (NCoR1) into an active repressor complex. However, in contradiction, biochemical and crystallographic studies have shown that heme decreases the affinity of the ligand-binding domain of Rev-erb NRs for NCoR1 peptides. One explanation for this discrepancy is that the ligand-binding domain and NCoR1 peptides used for in vitro studies cannot replicate the key features of the full-length proteins used in cellular studies. However, the combined in vitro and cellular results described here demonstrate that heme does not directly promote interactions between full-length Rev-erbβ (FLRev-erbβ) and an NCoR1 construct encompassing all three NR interaction domains. NCoR1 tightly binds both apo- and heme-replete FLRev-erbβ·DNA complexes; furthermore, heme, at high concentrations, destabilizes the FLRev-erbβ·NCoR1 complex. The interaction between FLRev-erbβ and NCoR1 as well as Rev-erbβ repression at the Bmal1 promoter appear to be modulated by another cellular factor(s), at least one of which is related to the ubiquitin-proteasome pathway. Our studies suggest that heme is involved in regulating the degradation of Rev-erbβ in a manner consistent with its role in circadian rhythm maintenance. Finally, the very slow rate constant (10(-6) s(-1)) of heme dissociation from Rev-erbβ rules out a prior proposal that Rev-erbβ acts as an intracellular heme sensor.

    2013-01-01

    This book provides essential information on metal forming, utilizing a practical distinction between bulk and sheet metal forming. In the field of bulk forming, it examines processes of cold, warm and hot bulk forming, as well as rolling and a new addition, the process of thixoforming. As for the field of sheet metal working, on the one hand it deals with sheet metal forming processes (deep drawing, flange forming, stretch drawing, metal spinning and bending). In terms of special processes, the chapters on internal high-pressure forming and high rate forming have been revised and refined. On the other, the book elucidates and presents the state of the art in sheet metal separation processes (shearing and fineblanking). Furthermore, joining by forming has been added to the new edition as a new chapter describing mechanical methods for joining sheet metals. The new chapter “Basic Principles” addresses both sheet metal and bulk forming, in addition to metal physics, plastomechanics and computational basics; ...

    We derive an analytic form of the Wang-Govind-Carter (WGC) [Wang , Phys. Rev. B 60, 16350 (1999)] kinetic energy density functional (KEDF) with the density-dependent response kernel. A real-space aperiodic implementation of the WGC KEDF is then described and used in linear scaling orbital-free density functional theory (OF-DFT) calculations.

  10. Maass Forms and Quantum Modular Forms

    Science.gov (United States)

    Rolen, Larry

    This thesis describes several new results in the theory of harmonic Maass forms and related objects. Maass forms have recently led to a flood of applications throughout number theory and combinatorics in recent years, especially following their development by the work of Bruinier and Funke the modern understanding Ramanujan's mock theta functions due to Zwegers. The first of three main theorems discussed in this thesis concerns the integrality properties of singular moduli. These are well-known to be algebraic integers, and they play a beautiful role in complex multiplication and explicit class field theory for imaginary quadratic fields. One can also study "singular moduli" for special non-holomorphic functions, which are algebraic but are not necessarily algebraic integers. Here we will explain the phenomenon of integrality properties and provide a sharp bound on denominators of symmetric functions in singular moduli. The second main theme of the thesis concerns Zagier's recent definition of a quantum modular form. Since their definition in 2010 by Zagier, quantum modular forms have been connected to numerous different topics such as strongly unimodal sequences, ranks, cranks, and asymptotics for mock theta functions. Motivated by Zagier's example of the quantum modularity of Kontsevich's "strange" function F(q), we revisit work of Andrews, Jimenez-Urroz, and Ono to construct a natural vector-valued quantum modular form whose components. The final chapter of this thesis is devoted to a study of asymptotics of mock theta functions near roots of unity. In his famous deathbed letter, Ramanujan introduced the notion of a mock theta function, and he offered some alleged examples. The theory of mock theta functions has been brought to fruition using the framework of harmonic Maass forms, thanks to Zwegers. Despite this understanding, little attention has been given to Ramanujan's original definition. Here we prove that Ramanujan's examples do indeed satisfy his

  11. Strong couplings and form factors of charmed mesons in holographic QCD

    We extend the two-flavor hard-wall holographic model of Erlich, Katz, Son, and Stephanov [Phys. Rev. Lett. 95, 261602 (2005), 10.1103/PhysRevLett.95.261602] to four flavors to incorporate strange and charm quarks. The model incorporates chiral and flavor symmetry breaking and provides a reasonable description of masses and weak decay constants of a variety of scalar, pseudoscalar, vector, and axial-vector strange and charmed mesons. In particular, we examine flavor symmetry breaking in the strong couplings of the ρ meson to the charmed D and D* mesons. We also compute electromagnetic form factors of the π , ρ , K , K*, D and D* mesons. We compare our results for the D and D* mesons with lattice QCD data and other nonperturbative approaches.

  13. Identification of new splice sites used for generation of rev transcripts in human immunodeficiency virus type 1 subtype C primary isolates.

    Directory of Open Access Journals (Sweden)

    Elena Delgado

    Full Text Available The HIV-1 primary transcript undergoes a complex splicing process by which more than 40 different spliced RNAs are generated. One of the factors contributing to HIV-1 splicing complexity is the multiplicity of 3' splice sites (3'ss used for generation of rev RNAs, with two 3'ss, A4a and A4b, being most commonly used, a third site, A4c, used less frequently, and two additional sites, A4d and A4e, reported in only two and one isolates, respectively. HIV-1 splicing has been analyzed mostly in subtype B isolates, and data on other group M clades are lacking. Here we examine splice site usage in three primary isolates of subtype C, the most prevalent clade in the HIV-1 pandemic, by using an in vitro infection assay of peripheral blood mononuclear cells. Viral spliced RNAs were identified by RT-PCR amplification using a fluorescently-labeled primer and software analyses and by cloning and sequencing the amplified products. The results revealed that splice site usage for generation of rev transcripts in subtype C differs from that reported for subtype B, with most rev RNAs using two previously unreported 3'ss, one located 7 nucleotides upstream of 3'ss A4a, designated A4f, preferentially used by two isolates, and another located 14 nucleotides upstream of 3'ss A4c, designated A4g, preferentially used by the third isolate. A new 5' splice site, designated D2a, was also identified in one virus. Usage of the newly identified splice sites is consistent with sequence features commonly found in subtype C viruses. These results show that splice site usage may differ between HIV-1 subtypes.

  20. Base-line investigations of birds in relation to an offshore wind farm at Horns Rev, and results from the year of construction

    The present report presents the base-line investigations of birds conducted during August 1999-April 2001 in relation to construction of an offshore wind farm at Horns Rev, 14 km west-south-west of Blaevandshuk, in the Danish North Sea. The report also presents data collected during the period September 2001-April 2002, when construction of the wind farm was in progress. The wind farm will consist of 80 wind turbines, each of 2 MW, and cover an area of c. 20 km{sup 2}. The eastern part of the North Sea constitutes major staging and wintering grounds for huge numbers of water- and seabirds. The area is also known to be an important site for migrating birds, which especially in autumn pass in large numbers. As Denmark has obligations to protect and maintain the bird populations it was laid down in the approval for erection of the wind farm that the impact on birds should be investigated. According to the 1% criteria defined in the Ramsar Convention, the eastern part of the North Sea including the wind farm area is of international importance to divers, Common Tern, and Sandwich Tern. A number of other species, e.g. Common Eider, Common Scoter, Guillemot and Razorbill, are present in the area in significant numbers as well, though these numbers do not make up 1% of the populations. Detailed distributions of birds in the area around and at Horns Rev were virtually unknown until initiation of this project. Previous bird counts in this area have been carried out almost exclusively from the coast and detailed knowledge exists concerning the numbers of roosting at and migrating birds from the westernmost point of Jutland, Blaevandshuk. To describe the numbers and distributions of birds staging and wintering in the Horns Rev area, bird investigations were initiated in 1999 by using standardised transect counts from aircraft. Up to April 2002, 18 aerial counts have been carried out over an area of c. 1,700 km{sup 2} centred on the Horns Rev project area. (au)
