    enteroantigen-presenting cells (APC) and CD4(+)CD25(+) T-regulatory cells (Tregs) in splenocyte-T cell proliferation assays. METHODS:: Splenocytes exposed to enteroantigen +/- probiotics were used to stimulate cultured CD4(+)CD25(-) T cells to which titrated numbers of Tregs were added. Cytokine assays were...... performed by use of neutralizing antibodies and ELISA. RESULTS:: Exposure of APCs to enteroantigens and the series of probiotic strains mentioned above did not influence the stimulatory capacity of APCs on proliferative enteroantigen-specific T cells. However, exposure to B. bifidum BI-98, BI-504 and L....... acidophilus NCFM consistently reduced the suppressive activity of Tregs. The suppressive activity was analyzed using fractionated components of the probiotics, and showed that a component of the cell wall is responsible for the decreased Treg activity in the system. The probiotic-induced suppression of Treg...

    Depression and generalized anxiety, separately and as comorbid states, continue to represent a significant public health challenge. Current cognitive-behavioral treatments are clearly beneficial but there remains a need for continued development of complementary interventions. This manuscript presents two proof-of-concept studies, in analog samples, of "microinterventions" derived from regulatory focus and regulatory fit theories and targeting dysphoric and anxious symptoms. In Study 1, participants with varying levels of dysphoric and/or anxious mood were exposed to a brief intervention either to increase or to reduce engagement in personal goal pursuit, under the hypothesis that dysphoria indicates under-engagement of the promotion system whereas anxiety indicates over-engagement of the prevention system. In Study 2, participants with varying levels of dysphoric and/or anxious mood received brief training in counterfactual thinking, under the hypothesis that inducing individuals in a state of promotion failure to generate subtractive counterfactuals for past failures (a non-fit) will lessen their dejection/depression-related symptoms, whereas inducing individuals in a state of prevention failure to generate additive counterfactuals for past failures (a non-fit) will lessen their agitation/anxiety-related symptoms. In both studies, we observed discriminant patterns of reduction in distress consistent with the hypothesized links between dysfunctional states of the two motivational systems and dysphoric versus anxious symptoms.

  16. Reducing nuclear power plant leadtimes: Many obstacles remain: Nuclear Regulatory Commission. Report to the Congress

    International Nuclear Information System (INIS)

    Today's large nuclear powerplants cost from $700 million to $1 billion to construct. Much of this cost--up to 40 percent, according to one study--is interest and inflation encountered during the 10 or more years of leadtime--the timespan from the date a utility decides to build a plant until the date it becomes operational. Presently, high capital costs have contributed to many utilities' decisions to defer or cancel construction of planned units. Thus, the leadtimes for constructing nuclear powerplants are important factors in the economics of nuclear power, and any reductions in the present 10-year cycle would reduce capital costs and enable a utility to more quickly begin recovering the cost of the plant. Reduced leadtimes would also provide earlier on-line electrical power to meet increased energy demands. For several years the President and the Joint Committee on Atomic Energy have been concerned about the lengthy leadtimes and the President has requested the Nuclear Regulatory Commission to take steps to reduce them. NRC has in recent years implemented certain administrative changes in an attempt to reduce nuclear powerplant leadtimes from 10 years to 7 to 8 years without compromising safety

  17. Dietary gluten reduces the number of intestinal regulatory T cells in mice

    It is well established that gluten-free diet reduces the incidence of type 1 diabetes mellitus (T1D) in non-obese diabetic (NOD) mice, though the mechanism is not known. However, regulatory T cells (Treg) are likely to play an important role. Also, it is known that dietary gluten induces an...... intestinal increase in the bacterium Lactococcus garvieae, but the importance of this phenomenon for T1D development is doubtful. Our hypothesis is that gluten is responsible for mediating its effect on T1D through the influence on Treg development independent of gluten-induced Lactococci. Four groups of...... female NOD and BALB / c mice of 3 week old were fed either a gluten-free diet or a standard diet. Lactococcus garvieae or saline water was administered per oral to one of each dietary group.

    Nitrous oxide (N2O) is an important greenhouse gas (GHG) with substantial global warming potential and also contributes to ozone depletion through photochemical nitric oxide (NO) production in the stratosphere. The negative effects of N2O on climate and stratospheric ozone make N2O mitigation an international challenge. More than 60% of global N2O emissions are emitted from agricultural soils mainly due to the application of synthetic nitrogen-containing fertilizers. Thus, mitigation strategies must be developed which increase (or at least do not negatively impact) on agricultural efficiency whilst decrease the levels of N2O released. This aim is particularly important in the context of the ever expanding population and subsequent increased burden on the food chain. More than two-thirds of N2O emissions from soils can be attributed to bacterial and fungal denitrification and nitrification processes. In ammonia-oxidizing bacteria, N2O is formed through the oxidation of hydroxylamine to nitrite. In denitrifiers, nitrate is reduced to N2 via nitrite, NO and N2O production. In addition to denitrification, respiratory nitrate ammonification (also termed dissimilatory nitrate reduction to ammonium) is another important nitrate-reducing mechanism in soil, responsible for the loss of nitrate and production of N2O from reduction of NO that is formed as a by-product of the reduction process. This review will synthesize our current understanding of the environmental, regulatory and biochemical control of N2O emissions by nitrate-reducing bacteria and point to new solutions for agricultural GHG mitigation.

  20. Chloroquine treatment enhances regulatory T cells and reduces the severity of experimental autoimmune encephalomyelitis.

    Directory of Open Access Journals (Sweden)

    Rodolfo Thomé

    Full Text Available BACKGROUND: The modulation of inflammatory processes is a necessary step, mostly orchestrated by regulatory T (Treg cells and suppressive Dendritic Cells (DCs, to prevent the development of deleterious responses and autoimmune diseases. Therapies that focused on adoptive transfer of Treg cells or their expansion in vivo achieved great success in controlling inflammation in several experimental models. Chloroquine (CQ, an anti-malarial drug, was shown to reduce inflammation, although the mechanisms are still obscure. In this context, we aimed to access whether chloroquine treatment alters the frequency of Treg cells and DCs in normal mice. In addition, the effects of the prophylactic and therapeutic treatment with CQ on Experimental Autoimmune Encephalomyelitis (EAE, an experimental model for human Multiple Sclerosis, was investigated as well. METHODOLOGY/PRINCIPAL FINDINGS: EAE was induced in C57BL/6 mice by immunization with myelin oligodendrocyte glycoprotein (MOG35-55 peptide. C57BL/6 mice were intraperitoneally treated with chloroquine. Results show that the CQ treatment provoked an increase in Treg cells frequency as well as a decrease in DCs. We next evaluated whether prophylactic CQ administration is capable of reducing the clinical and histopathological signs of EAE. Our results demonstrated that CQ-treated mice developed mild EAE compared to controls that was associated with lower infiltration of inflammatory cells in the central nervous system CNS and increased frequency of Treg cells. Also, proliferation of MOG35-55-reactive T cells was significantly inhibited by chloroquine treatment. Similar results were observed when chloroquine was administrated after disease onset. CONCLUSION: We show for the first time that CQ treatment promotes the expansion of Treg cells, corroborating previous reports indicating that chloroquine has immunomodulatory properties. Our results also show that CQ treatment suppress the inflammation in the CNS of

    Full Text Available BACKGROUND: Photo(chemotherapy is widely used to treat psoriasis, the pathogenesis of which might be caused by an imbalance of Th17 cells/regulatory T cells (Treg. In the present study, we evaluated the effects of photo(chemotherapy on the Th17/Treg balance and Treg function. METHODS: Peripheral blood was obtained from psoriasis patients treated with bath-psoralen ultraviolet A (UVA, n = 50 or narrowband ultraviolet B (UVB, n = 18, and age-matched healthy volunteers (n = 20. CD3(+CD4(+IL-17A(+ or CD4(+CD25(+Foxp3(+cells were analyzed to estimate Th17 or Treg number by fluorescence-activated cell sorting. Moreover, CD4(+ CD25(- T cells from patients treated with PUVA(n = 14 were incubated in CFSE and activated with or without CD4(+ CD25(+T cells, and the suppressive function of CD4(+ CD25(+T cells were analyzed. RESULTS: Photo(chemotherapy significantly reduced Th17 levels from 5.66 ± 3.15% to 2.96 ± 2.89% in patients with increased Th17 (Th17/CD4>3.01% [mean+SD of controls]. In contrast, photo(chemotherapy significantly increased Treg levels from 2.77 ± 0.75 to 3.40 ± 1.88% in patients with less than 4.07% Treg level, defined as the mean of controls. Furthermore, while Treg suppressed the CD4(+CD25(- T cell proliferation to a greater extent in controls (Treg Functional Ratio 94.4 ± 4.28% than in patients (70.3±25.1%, PUVA significantly increased Treg Functional Ratio to 88.1 ± 6.47%. Th17 levels in severe patients (>30 PASI were significantly higher as compared to controls. Th17 levels that were left after treatment in the patients not achieving PASI 50 (3.78 ± 4.18% were significantly higher than those in the patients achieving PASI 75 (1.83±1.87%. Treg levels in patients achieving PASI 90 (4.89 ± 1.70% were significantly higher than those in the patients not achieving PASI 90 (3.90 ± 1.66%. Treg levels prior to treatment with Th17 high decreased group (5.16 ± 2.20% was significantly higher than that with Th17 high increased group

    The avian bacterial pathogen Mycoplasma gallisepticum is a good model for systems studies due to small genome and simplicity of regulatory pathways. In this study, we used RNA-Seq and MS-based proteomics to accurately map coding sequences, transcription start sites (TSSs) and transcript 3'-ends (T3Es). We used obtained data to investigate roles of TSSs and T3Es in stress-induced transcriptional responses. We identified 1061 TSSs at a false discovery rate of 10% and showed that almost all transcription in M. gallisepticum is initiated from classic TATAAT promoters surrounded by A/T-rich sequences. Our analysis revealed the pronounced operon structure complexity: on average, each coding operon has one internal TSS and T3Es in addition to the primary ones. Our transcriptomic approach based on the intervals between the two nearest transcript ends allowed us to identify two classes of T3Es: strong, unregulated, hairpin-containing T3Es and weak, heat shock-regulated, hairpinless T3Es. Comparing gene expression levels under different conditions revealed widespread and divergent transcription regulation in M. gallisepticum. Modeling suggested that the core promoter structure plays an important role in gene expression regulation. We have shown that the heat stress activation of cryptic promoters combined with the hairpinless T3Es suppression leads to widespread, seemingly non-functional transcription. PMID:25361977

  9. Reducing regulatory and economic uncertainty in the next generation of U.S. nuclear power plants

    International Nuclear Information System (INIS)

    Nuclear Power Plants have accounted for 40% of all new electricity supplied in the last 25 years. Nuclear energy and coal fired plants together account for approximately three quarters of the current electricity supply.In addition to assuring reliability and diversity of energy supply, U.S. nuclear plants proved their value in another critical area of the national energy policy-managing environmental impacts.Since 1973, the use of nuclear energy in lieu of fossil fuels has prevented the emission of more than 2 billion tons of carbon in the form of carbon dioxide, 80 million tons of sulfur dioxide and 35 million tons of nitrogen oxides. Now looking ahead to the next 25 years, the challenge is to maintain reliability of energy supply, while meeting increasingly urgent needs to minimize environmental impacts from the electricity sector. Fossil fired power plants face increasing regulatory requirements and constraints on emissions.The response to the challenges of the future must include aggressive development of renewable energy sources and increased reliance on nuclear energy-the only non-emitting sources of electricity available for deployment in the near term.(DM)

  10. Reconciling Estimates of the Value to Firms of Reduced Regulatory Delay in the Marketing of Their New Drugs.

    Science.gov (United States)

    Wilmoth, Daniel R

    2015-12-01

    The prescription drug user fee program provides additional resources to the U.S. Food and Drug Administration at the expense of regulated firms. Those resources accelerate the review of new drugs. Faster approvals allow firms to realize profits sooner, and the program is supported politically by industry. However, published estimates of the value to firms of reduced regulatory delay vary dramatically. It is shown here that this variation is driven largely by differences in methods that correspond to differences in implicit assumptions about the effects of reduced delay. Theoretical modeling is used to derive an equation describing the relationship between estimates generated using different methods. The method likely to yield the most accurate results is identified. A reconciliation of published estimates yields a value to a firm for a one-year reduction in regulatory delay at the time of approval of about $60 million for a typical drug. Published 2015. This article is a U.S. Government work and is in the public domain in the U.S.A. PMID:25753390

    Sarcoidosis can evolve into a chronic disease with persistent granulomas accompanied by progressive fibrosis. While an unlimited inflammatory response suggests an impaired immune control in sarcoid lesions, it stands in contrast to the massive infiltration with CD4(+)CD25(high)FoxP3(+) regulatory T cells. We here revealed that those Treg cells in affected lung lesions were mainly derived from activated natural Treg cells with GARP (LRRC32)-positive phenotype but exhibited reduced repressor capacities despite high IL-10 and TGF-beta 1 levels. The repressive capacity of blood Treg cells, in contrast, was not impaired compared to age-matched healthy donors. Treg derived cells in granuloma lesions have undergone extensive rounds of amplifications indicated by shortened telomeres compared to blood Treg cells of the same patient. Lesional Treg derived cells moreover secreted pro-inflammatory cytokines including IL-4 which sustains granuloma formation through fibroblast amplification and the activation of mast cells, the latter indicated by the expression of membrane-bound oncostatin M.

    Martin Montes

    Full Text Available BACKGROUND: Human strongyloidiasis varies from a chronic but limited infection in normal hosts to hyperinfection in patients treated with corticosteroids or with HTLV-1 co-infection. Regulatory T cells dampen immune responses to infections. How human strongyloidiasis is controlled and how HTLV-1 infection affects this control are not clear. We hypothesize that HTLV-1 leads to dissemination of Strongyloides stercoralis infection by augmenting regulatory T cell numbers, which in turn down regulate the immune response to the parasite. OBJECTIVE: To measure peripheral blood T regulatory cells and Strongyloides stercoralis larval antigen-specific cytokine responses in strongyloidiasis patients with or without HTLV-1 co-infection. METHODS: Peripheral blood mononuclear cells (PBMCs were isolated from newly diagnosed strongyloidiasis patients with or without HTLV-1 co-infection. Regulatory T cells were characterized by flow cytometry using intracellular staining for CD4, CD25 and FoxP3. PBMCs were also cultured with and without Strongyloides larval antigens. Supernatants were analyzed for IL-5 production. RESULTS: Patients with HTLV-1 and Strongyloides co-infection had higher parasite burdens. Eosinophil counts were decreased in the HTLV-1 and Strongyloides co-infected subjects compared to strongyloidiasis-only patients (70.0 vs. 502.5 cells/mm(3, p = 0.09, Mann-Whitney test. The proportion of regulatory T cells was increased in HTLV-1 positive subjects co-infected with strongyloidiasis compared to patients with only strongyloidiasis or asymptomatic HTLV-1 carriers (median = 17.9% vs. 4.3% vs. 5.9 p<0.05, One-way ANOVA. Strongyloides antigen-specific IL-5 responses were reduced in strongyloidiasis/HTLV-1 co-infected patients (5.0 vs. 187.5 pg/ml, p = 0.03, Mann-Whitney test. Reduced IL-5 responses and eosinophil counts were inversely correlated to the number of CD4+CD25+FoxP3+ cells. CONCLUSIONS: Regulatory T cell counts are increased in patients with

The paper discusses some methods of solving this problem. These methods can be considered preventive and are aimed at developing and implementing an appropriate national regulatory policy in the sphere of activities with sealed sources. This policy includes a wide spectrum of measures, from political steps to the creation of a State computerized inventory system, and leads to a reduction of the quantity of radiation sources that require processing, storage and disposal in Ukraine. The content, purpose and phases of realization of each component of this policy in Ukraine are discussed. (author)

    Clinical manifestations in onchocerciasis range from generalized onchocerciasis (GEO) to the rare but severe hyperreactive (HO)/sowda form. Since disease pathogenesis is associated with host inflammatory reactions, we investigated whether Th17 responses could be related to aggravated pathology in HO. Using flow cytometry, filarial-specific cytokine responses and PCR arrays, we compared the immune cell profiles, including Th subsets, in individuals presenting the two polar forms of infection and endemic normals (EN). In addition to elevated frequencies of memory CD4+ T cells, individuals with HO showed accentuated Th17 and Th2 profiles but decreased CD4+CD25hiFoxp3+ regulatory T cells. These profiles included increased IL-17A+, IL-4+, RORC2+ and GATA3+CD4+ T cell populations. Flow cytometry data was further confirmed using a PCR array since Th17-related genes (IL-17 family members, IL-6, IL-1β and IL-22) and Th2-related (IL-4, IL-13, STAT6) genes were all significantly up-regulated in HO individuals. In addition, stronger Onchocerca volvulus-specific Th2 responses, especially IL-13, were observed in vitro in hyperreactive individuals when compared to GEO or EN groups. This study provides initial evidence that elevated frequencies of Th17 and Th2 cells form part of the immune network instigating the development of severe onchocerciasis. PMID:25569210

    Tissue inhibitor of metalloproteinase 1 (TIMP-1) controls matrix metalloproteinase activity through 1:1stoichiometric binding. Human TIMP-1 fused to a glycosylphosphatidylinositol(GPI) anchor (TIMP-1 - GPI) shifts the activity of TIMP-1 from the extracellular matrix to the cell surface. TIMP-1 - GPI treated renal cell carcinoma cells show increased apoptosis and reduced proliferation.Transcriptomic profiling and regulatory pathway mapping were used to identify the potential mechanisms driving these effects. Significant changes in the DNA binding inhibitors, TGF- β 1/SMAD and BMP pathways resulted from TIMP-1 - GPI treatment. These events were linked to reduced TGF- β 1 signaling mediated by inhibition of proteolytic processing of latent TGF- β 1 by TIMP-1 - GPI. PMID:23667903

    Bacterial β-(1,3)-glucan has more advantages in terms of cost, yield and efficiency than that derived from mushrooms, plants, yeasts and fungi. We have previously developed a novel and high-yield β-(1,3)-glucan produced by Agrobacterium sp. R259. This study aimed to elucidate the functional mechanism and therapeutic efficacy of bacterial β-(1,3)-glucan in dextran sulfate sodium (DSS)-induced inflammatory bowel disease (IBD).Mice were orally pretreated with bacterial β-(1,3)-glucan at daily doses of 2.5 or 5mg/kg for 2 weeks. After 6 days of DSS treatment, clinical assessment of IBD severity and expression of pro-inflammatory cytokines were evaluated. In vivo cell proliferation was examined by immunohistochemistry using Ki-67 and ER-TR7 antibodies. The frequency of regulatory T cells (Tregs) was analyzed by flow cytometry. Natural killer (NK) activity and IgA level were evaluated using NK cytotoxicity assay and ELISA.The deterioration of body weight gain, colonic architecture, disease score and histological score was recovered in DSS-induced IBD mice when pretreated with bacterial β-(1,3)-glucan. The recruitment of macrophages and the gene expression of proinflammatory cytokines, such as IL-1β, IL-6 and IL-17A/F, were markedly decreased in the colon of β-(1,3)-glucan-pretreated mice. β-(1,3)-Glucan induced the recovery of Tregs in terms of their frequency in DSS-induced IBD mice. Intriguingly, β-(1,3)-glucan reversed the functional defects of NK cells and excessive IgA production in DSS-induced IBD mice.We conclude that bacterial β-(1,3)-glucan prevented the progression of DSS-induced IBD by recovering the reduction of Tregs, functional defect of NK cells and excessive IgA production.

  20. Regulatory and economic instruments in order to reduce emissions of greenhouse gases by 2050: financial impacts on industry?

    International Nuclear Information System (INIS)

    Industrial groups will be exposed to increasingly stringent regulation measures against GHG emissions. Uncertainties over the form and extent of international cooperation on climate change should not begin to weaken the European voluntarism otherwise than concerning the targets level of ambition. Therefore, the degree of restraint will remain strong. Halving global emissions between 1990 and 2050 will involve a reduction by a factor of 4 of those in developed countries. However, given the difficulty of achieving such a goal in the diffuse sectors (households, agriculture, transport...), the European industry will most likely reduce its GHG emissions by a factor of 5 to 6.

    State-level statutes provide firms that engage in environmental self-audits, and that self-report their environmental violations, with a variety of different regulatory rewards, including "immunity" from penalties and "privilege" for information contained in self-audits. This paper studies a panel of State-level industries from 1989-2003, in order to determine the effects of the different statutes on toxic pollution and government inspections. We find that, by encouraging self-auditing, privi...

    Glioblastoma multiforme (GBM) is an aggressive malignancy associated with profound host immunosuppression mediated in part by FoxP3 expressing regulatory CD4+ T lymphocytes (Tregs) that down-regulate anti-tumor immunity. In order to assess whether FoxP3 was an independent driver differentially expressed in primary versus recurrent GBMs, we stained resected primary and recurrent GBM tumors for CD3, CD4, CD8 and FoxP3 expression using standard immunohistochemistry. Slides were scanned with a hi...

    ) muscles at 4 h of recovery following in vitro stimulations (either short intensive (SHO) 60 Hz, 5 min, or prolonged moderate (PRO) 20 Hz, 40 min). Stimulation induced acute regulation of the mRNA level of Ca(2+)-regulating proteins in a manner that does not follow typical fibre-type-specific transitions....... In general, stimulation decreased mRNA content of all proteins studied. Most prominent down-regulation was observed for Cacna1 (26 and 32 % after SHO and PRO, respectively, in SOL; 19 % after SHO in EDL). SERCA1, SERCA2, CASQ1, CASQ2, and RyR1 mRNA content also decreased significantly in both muscles...... relative to resting control. Of notice is that hexokinase II mRNA content was increased in EDL and unchanged in SOL underlining the specificity of the down-regulation of mRNA of Ca(2+) regulatory proteins.

  7. Freeze and Thaw of CD4+CD25+Foxp3+ Regulatory T Cells Results in Loss of CD62L Expression and a Reduced Capacity to Protect against Graft-versus-Host Disease.

    Directory of Open Access Journals (Sweden)

    Mareike Florek

    Full Text Available The adoptive transfer of CD4+CD25+Foxp3+ regulatory T cells (Tregs in murine models of allogeneic hematopoietic cell transplantation (HCT has been shown to protect recipient mice from lethal acute graft-versus-host disease (GVHD and this approach is being actively investigated in human clinical trials. Here, we examined the effects of cryopreservation on Tregs. We found that freeze and thaw of murine and human Tregs is associated with reduced expression of L-selectin (CD62L, which was previously established to be an important factor that contributes to the in vivo protective effects of Tregs. Frozen and thawed murine Tregs showed a reduced capacity to bind to the CD62L binding partner MADCAM1 in vitro as well as an impaired homing to secondary lymphoid organs in vivo. Upon adoptive transfer frozen and thawed Tregs failed to protect against lethal GVHD compared with fresh Tregs in a murine model of allogeneic HCT across major histocompatibility barriers. In summary, the direct administration of adoptively transferred frozen and thawed Tregs adversely affects their immunosuppressive potential which is an important factor to consider in the clinical implementation of Treg immunotherapies.

  8. Virginia Power's regulatory reduction program

    International Nuclear Information System (INIS)

    Virginia Power has two nuclear plants, North Anna and Surry Power Stations, which have two units each for a total of four nuclear units. In 1992, the Nuclear Regulatory Commission solicited comments from the nuclear industry to obtain their ideas for reducing the regulatory burden on nuclear facilities. Pursuant to the new regulatory climate, Virginia Power developed an internal program to evaluate and assess the regulatory and self-imposed requirements to which they were committed, and to pursue regulatory relief or internal changes where possible and appropriate. The criteria were that public safety must be maintained, and savings must be significant. Up to the date of the conference, over US$22 million of one-time saving had been effected, and US$2.75 million in annual savings

    As noted elsewhere in this report, a central goal of the Extended Duration Orbiter Medical Project (EDOMP) was to ensure that cardiovascular and muscle function were adequate to perform an emergency egress after 16 days of spaceflight. The goals of the Regulatory Physiology component of the EDOMP were to identify and subsequently ameliorate those biochemical and nutritional factors that deplete physiological reserves or increase risk for disease, and to facilitate the development of effective muscle, exercise, and cardiovascular countermeasures. The component investigations designed to meet these goals focused on biochemical and physiological aspects of nutrition and metabolism, the risk of renal (kidney) stone formation, gastrointestinal function, and sleep in space. Investigations involved both ground-based protocols to validate proposed methods and flight studies to test those methods. Two hardware tests were also completed.

  10. Accumulation of CCR4⁺CTLA-4 FOXP3⁺CD25(hi regulatory T cells in colon adenocarcinomas correlate to reduced activation of conventional T cells.

    Directory of Open Access Journals (Sweden)

    Helena Svensson

    Full Text Available BACKGROUND: Colorectal cancer usually gives rise to a specific anti-tumor immune response, but for unknown reasons the resulting immunity is not able to clear the tumor. Recruitment of activated effector lymphocytes to the tumor is important for efficient anti-tumor responses, while the presence of regulatory T cells (Treg down-modulate tumor-specific immunity. We therefore aimed to determine homing mechanisms and activation stage of Treg and effector T cell infiltrating colon tumors compared to cells from the unaffected mucosa in patients suffering from colon adenocarcinoma. METHODOLOGY/PRINCIPAL FINDINGS: Lymphocytes were isolated from unaffected and tumor mucosa from patients with colon adenocarcinoma, and flow cytometry, immunohistochemistry, and quantitative PCR was used to investigate the homing mechanisms and activation stage of infiltrating Treg and conventional lymphocytes. We detected significantly higher frequencies of CD25(highFOXP3⁺CD127(low putative Treg in tumors than unaffected mucosa, which had a complete demethylation in the FOXP3 promotor. Tumor-associated Treg had a high expression of CTLA-4, and some appeared to be antigen experienced effector/memory cells based on their expression of αEβ7 (CD103. There were also significantly fewer activated T cells and more CTLA-4⁺ conventional T cells susceptible to immune regulation in the tumor-associated mucosa. In contrast, CD8⁺granzyme B⁺ putative cytotoxic cells were efficiently recruited to the tumors. The frequencies of cells expressing α4β7 and the Th1 associated chemokine receptor CXCR3 were significantly decreased among CD4⁺ T cells in the tumor, while frequencies of CD4⁺CCR4⁺ lymphocytes were significantly increased. CONCLUSIONS/SIGNIFICANCE: This study shows that CCR4⁺CTLA4(hi Treg accumulate in colon tumors, while the frequencies of activated conventional Th1 type T cells are decreased. The altered lymphocyte composition in colon tumors will probably

  11. Regulatory strategies. Topical issue 6

    International Nuclear Information System (INIS)

    The regulatory programmes established by Member States that use radioactive materials, handle radioactive waste or have nuclear installations vary depending on the size and scope of the regulated activities, historical evolution, government and industry structures. The main changes in external factors which will further affect the regulatory programmes include stagnation in the development of nuclear power, the increased economic competition of energy suppliers, ageing plants, continued growth in the industrial and medical uses of radioactive materials, delays in high level waste facilities and the reduced availability of trained personnel. Eight areas are discussed with the objective of identifying ways in which the IAEA can assist Member States to anticipate and respond to changing external factors and facilitate beneficial harmonization of regulatory practices. (1) Regulatory approaches are continuing to evolve among Member States with a general tendency towards less prescriptive practices. (2) Key elements in enhancing safety culture are an open regulator-regulated dialogue and the use of peer reviews by external or international organizations. (3) The efficiency and effectiveness of regulatory bodies is intimately related to the implementation of modem business practices and the hiring and retention of highly qualified staff that keep abreast of developing technology. (4) While nuclear power plant safety performance has improved worldwide, political, economic and social factors combine to make regulatory decisions increasingly difficult. (5) Harmonization of national safety criteria and decisions has largely occurred through the efforts of the IAEA in developing standards, promulgating conventions and hosting peer discussions in a number of forums. (6) Regulatory bodies generally acknowledge the value of probabilistic safety assessment (PSA) methodology as a complementary tool to deterministic safety analysis methods.

  13. First update to the US Nuclear Regulatory Commission's regulatory strategy for the high-level waste repository program

    International Nuclear Information System (INIS)

    The US Nuclear Regulatory Commission (NRC) staff has updated its initial regulatory strategy for the High-Level Waste Repository Licensing Program. The update describes changes to the initial strategy and summarizes progress and future activities. This paper summarizes the first update of the regulatory strategy. In general the overall strategy of identifying and reducing uncertainties is unchanged. Identifying regulatory and institutional uncertainties is essentially complete, and therefore, the current and future emphasis is on reducing those regulatory and institutional uncertainties identified to date. The NRC staff has improved the methods of reducing regulatory uncertainties by (1) enhancing the technical basis preparation process for potential rulemakings and guidance and (2) designing a new guidance document, called a staff position, for clarifying regulatory uncertainties. For guiding the US DOE's reduction of technical uncertainties, the NRC staff will give more emphasis to prelicense application reviews and less emphasis on preparing staff technical positions

    Recently, gain-of-function (GOF) mutations in the gene encoding signal transducer and activator of transcription 1 (STAT1) have been associated with chronic mucocutaneous candidiasis (CMC). This case report describes a 10-year-old boy presenting with signs of common variable immunodeficiency (CVID), failure to thrive, impaired neurological development, and a history of recurrent mucocutaneous Candida infections. Sequencing of the STAT1 gene identified a heterozygous missense mutation in exon 7 encoding the STAT1 coiled-coil domain (c.514T>C, p.Phe172Leu). In addition to hypogammaglobulinemia with B-cell deficiency, and a low percentage of Th17 cells, immunological analysis of the patient revealed a marked depletion of forkhead-box P3(+)-expressing regulatory T cells (Tregs). In vitro stimulation of T cells from the patient with interferon-α (IFNα) and/or IFNɣ resulted in a significantly increased expression of STAT1-regulated target genes such as MIG1, IRF1, MX1, MCP1/CCL2, IFI-56K, and CXCL10 as compared to IFN-treated cells from a healthy control, while no IFNα/ɣ-mediated up-regulation of the FOXP3 gene was found. These data demonstrate that the STAT1 GOF mutation F172L, which results in impaired stability of the antiparallel STAT1 dimer conformation, is associated with inhibited Treg cell development and neurological symptoms.

    Regulatory T cells (Tregs) play an important role in the pathogenesis of HIV-1 infection and they frequently express the chemokine receptor CCR5. We therefore investigated whether antiretroviral treatment with the CCR5 antagonist Maraviroc affected Tregs in chronically HIV-1-infected individuals. HIV-1-infected patients with high viral loads had elevated frequencies of activated Tregs in the peripheral blood compared with healthy controls. In patients successfully treated with antiretroviral drugs (undetectable viral loads), the frequency and the activation status of Tregs were comparable with healthy controls without any specific effect related to the treatment with Maraviroc. These results indicate that the control of viral replication in general rather than a direct binding of Maraviroc to CCR5-positive Tregs influences Treg responses in successfully treated chronically HIV-1-infected individuals.

    The Interstate Oil and Gas Compact Commission (IOGCC) engaged in numerous projects outlined under the scope of work discussed in the United States Department of Energy (DOE) grant number DE-FC26-04NT15456 awarded to the IOGCC. Numerous projects were completed that were extremely valuable to state oil and gas agencies as a result of work performed utilizing resources provided by the grant. There are numerous areas in which state agencies still need assistance. This additional assistance will need to be addressed under future scopes of work submitted annually to DOE's Project Officer for this grant. This report discusses the progress of the projects outlined under the grant scope of work for the 2005-2006 areas of interest, which are as follows: Area of Interest No. 1--Regulatory Streamlining and Improvement: This area of interest continues to support IOGCC's regulatory streamlining efforts that include the identification and elimination of unnecessary duplications of efforts between and among state and federal programs dealing with exploration and production on public lands. Area of Interest No. 2--Technology: This area of interest seeks to improve efficiency in states through the identification of technologies that can reduce costs. Area of Interest No. 3--Training and Education: This area of interest is vital to upgrading the skills of regulators and industry alike. Within the National Energy Policy, there are many appropriate training and education opportunities. Education was strongly endorsed by the President's National Energy Policy Development group. Acting through the governors offices, states are very effective conduits for the dissemination of energy education information. While the IOGCC favors the development of a comprehensive, long-term energy education plan, states are also supportive of immediate action on important concerns, such as energy prices, availability and conservation. Area of Interest No. 4--Resource Assessment and

    Abstract Background Lysyl-tRNA synthetase (LysRS) is unique within the aminoacyl-tRNA synthetase family in that both class I (LysRS1) and class II (LysRS2) enzymes exist. LysRS1 enzymes are found in Archaebacteria and some eubacteria while all other organisms have LysRS2 enzymes. All sequenced strains of Bacillus cereus (except AH820) and Bacillus thuringiensis however encode both a class I and a class II LysRS. The lysK gene (encoding LysRS1) of B. cereus strain 14579 has an associated T box element, the first reported instance of potential T box control of LysRS expression. Results A global study of 891 completely sequenced bacterial genomes identified T box elements associated with control of LysRS expression in only four bacterial species: B. cereus, B. thuringiensis, Symbiobacterium thermophilum and Clostridium beijerinckii. Here we investigate the T box element found in the regulatory region of the lysK gene in B. cereus strain 14579. We show that this T box element is functional, responding in a canonical manner to an increased level of uncharged tRNALys but, unusually, also responding to an increased level of uncharged tRNAAsn. We also show that B. subtilis strains with T box regulated expression of the endogenous lysS or the heterologous lysK genes are viable. Conclusions The T box element controlling lysK (encoding LysRS1) expression in B. cereus strain 14579 is functional, but unusually responds to depletion of charged tRNALys and tRNAAsn. This may have the advantage of making LysRS1 expression responsive to a wider range of nutritional stresses. The viability of B. subtilis strains with a single LysRS1 or LysRS2, whose expression is controlled by this T box element, makes the rarity of the occurrence of such control of LysRS expression puzzling.

    Full Text Available Abstract Background Lysyl-tRNA synthetase (LysRS is unique within the aminoacyl-tRNA synthetase family in that both class I (LysRS1 and class II (LysRS2 enzymes exist. LysRS1 enzymes are found in Archaebacteria and some eubacteria while all other organisms have LysRS2 enzymes. All sequenced strains of Bacillus cereus (except AH820 and Bacillus thuringiensis however encode both a class I and a class II LysRS. The lysK gene (encoding LysRS1 of B. cereus strain 14579 has an associated T box element, the first reported instance of potential T box control of LysRS expression. Results A global study of 891 completely sequenced bacterial genomes identified T box elements associated with control of LysRS expression in only four bacterial species: B. cereus, B. thuringiensis, Symbiobacterium thermophilum and Clostridium beijerinckii. Here we investigate the T box element found in the regulatory region of the lysK gene in B. cereus strain 14579. We show that this T box element is functional, responding in a canonical manner to an increased level of uncharged tRNALys but, unusually, also responding to an increased level of uncharged tRNAAsn. We also show that B. subtilis strains with T box regulated expression of the endogenous lysS or the heterologous lysK genes are viable.

    The Office of Civilian Radioactive Waste Management (OCRWM) Program Management System Manual requires preparation of the OCRWM Regulatory Guidance Document (RGD) that addresses licensing, environmental compliance, and safety and health compliance. The document provides: regulatory compliance policy; guidance to OCRWM organizational elements to ensure a consistent approach when complying with regulatory requirements; strategies to achieve policy objectives; organizational responsibilities for regulatory compliance; guidance with regard to Program compliance oversight; and guidance on the contents of a project-level Regulatory Compliance Plan. The scope of the RGD includes site suitability evaluation, licensing, environmental compliance, and safety and health compliance, in accordance with the direction provided by Section 4.6.3 of the PMS Manual. Site suitability evaluation and regulatory compliance during site characterization are significant activities, particularly with regard to the YW MSA. OCRWM`s evaluation of whether the Yucca Mountain site is suitable for repository development must precede its submittal of a license application to the Nuclear Regulatory Commission (NRC). Accordingly, site suitability evaluation is discussed in Chapter 4, and the general statements of policy regarding site suitability evaluation are discussed in Section 2.1. Although much of the data and analyses may initially be similar, the licensing process is discussed separately in Chapter 5. Environmental compliance is discussed in Chapter 6. Safety and Health compliance is discussed in Chapter 7.

  11. Managing Regulatory Body Competence

    International Nuclear Information System (INIS)

    In 2001, the IAEA published TECDOC 1254, which examined the way in which the recognized functions of a regulatory body for nuclear facilities results in competence needs. Using the systematic approach to training (SAT), TECDOC 1254 provided a framework for regulatory bodies for managing training and developing and their maintaining their competence. It has been successfully used by many regulators. The IAEA has also introduced a methodology and an assessment tool - Guidelines for Systematic Assessment of Regulatory Competence Needs (SARCoN) - which provides practical guidance on analysing the training and development needs of a regulatory body and, through a gap analysis, guidance on establishing competence needs and how to meet them. In 2009, the IAEA established a steering committee (supported by a bureau) with the mission to advise the IAEA on how it could best assist Member States to develop suitable competence management systems for their regulatory bodies. The committee recommended the development of a safety report on managing staff competence as an integral part of a regulatory body's management system. This Safety Report was developed in response to this request. It supersedes TECDOC 1254, broadens its application to regulatory bodies for all facilities and activities, and builds upon the experience gained through the application of TECDOC 1254 and SARCoN and the feedback received from Member States. This Safety Report applies to the management of adequate competence as needs change, and as such is equally applicable to the needs of States 'embarking' on a nuclear power programme. It also deals with the special case of building up the competence of regulatory bodies as part of the overall process of establishing an 'embarking' State's regulatory system

    International Nuclear Information System (INIS)

    The US Nuclear Regulatory Commission has initiated a program to identify regulatory requirements associated with 10 CFR 50 that, if deleted or appropriately modified, would improve the efficiency and effectiveness of the NRC regulatory program without adversely affecting safety (October 3, 1984, ''Federal Register,'' 49 FR 39066). This report describes the results of a study conducted by Pacific Northwest Laboratory (PNL) to assist the NRC in executing the program. The report identifies 45 regulatory requirements (and associated regulatory guidance) that could potentially be relaxed or eliminated to reduce regulatory burdens without compromising public health and safety. If subsequent, more detailed studies and evaluations confirm these initial findings, NRC staff will recommend and implement appropriate regulatory changes, which may include modification or elimination of some requirements

    Mesenchymal stem cells attenuate the severity of lung injury due to their immunomodulatory properties. The effect of bone marrow-derived mesenchymal stem cells on asthma is seldom reported. We have examined the effect of BMSCs on airway inflammation in asthma. Forty female BALB/c mice were equally randomised into PBS group, BMSCs treatment group, BMSCs control group and asthmatic group. Reactivity of the airway to acetylcholine was measured by barometric plethysmography. Cytokine profiles of bronchoalveolar lavage fluid and serum were determined by enzyme-linked immunosorbent assay. Morphometric analysis was done with haematoxylin and periodic-acid Schiff staining. Engraftment of BMSCs in asthmatic mice significantly decreased the number of eosinophils and mononuclear cells in bronchoalveolar lavage fluid and the airway (P cell hyperplasia and responsiveness to acetylcholine were significantly reduced in BMSCs treatment groups. Moreover, BMSCs engraftment caused significant increases the ratio of Treg in pulmonary lymph node and interleukin-10 (IL-10) and interleukin-12 levels in BALF and serum. We conclude that BMSCs engraftment ameliorated airway inflammation and improved lung function in asthmatic mouse and the protective effect might be mediated by upregulating Treg and partly involved with increasing IL-10.

  19. Pollution prevention: A regulatory update

    International Nuclear Information System (INIS)

    Pollution prevention is the emphasis of the 1990s environmental philosophy. This new environmental era was ushered in when President Bush signed the Pollution Prevention Act in October 1990. This law, with its accompanying philosophy, was in response to the realization that end-of-the-pipe treatment, which frequently changed the media in which a pollutant or waste was discharged, was inadequate to protect the environment and human health. Pollution prevention advocates source reduction, where material substitutions and engineering solutions are sought to reduce the volume and toxicity of waste and pollutants. This proactive approach reduces environmental impacts such as those of former waste sites which have produced environmental legacies that will cost billions of dollars and take decades to remediate. This paper describes pollution prevention philosophy and summarizes regulatory pollution prevention requirements. It describes current regulatory trends in the area of pollution prevention, including voluntary programs and enforcement actions. The Pollution Prevention Act of 1990 is described, and pollution prevention initiatives embodied in other laws, including the Clean Air Act, the Clean Water Act, the Emergency Planning and Community Right-To-Know Act, the Resource Conservation and Recovery Act, and the Toxic Substances Control Act, are discussed. A historical overview of waste minimization initiatives within the Department of Energy is given, and other pollution prevention initiatives that affect federal facilities, such as Executive Order 12780, which mandates recycling and the procurement of recycled materials, are also outlined

    2007-01-01

    NASA Headquarters Environmental Management Division supports NASA's mission to pioneer the future in space exploration, scientific discovery, and aeronautics research by integrating environmental considerations into programs and projects early-on, thereby proactively reducing NASA's exposure to institutional, programmatic and operational risk. As part of this effort, NASA established the Principal Center for Regulatory Risk Analysis and Communication (RRAC PC) as a resource for detecting, analyzing, and communicating environmental regulatory risks to the NASA stakeholder community. The RRAC PC focuses on detecting emerging environmental regulations and other operational change drivers that may pose risks to NASA programs and facilities, and effectively communicating the potential risks. For example, regulatory change may restrict how and where certain activities or operations may be conducted. Regulatory change can also directly affect the ability to use certain materials by mandating a production phase-out or restricting usage applications of certain materials. Regulatory change can result in significant adverse impacts to NASA programs and facilities due to NASA's stringent performance requirements for materials and components related to human-rated space vehicles. Even if a regulation does not directly affect NASA operations, U.S. and international regulations can pose program risks indirectly through requirements levied on manufacturers and vendors of components and materials. For example, manufacturers can change their formulations to comply with new regulatory requirements. Such changes can require time-consuming and costly requalification certification for use in human spaceflight programs. The RRAC PC has implemented a system for proactively managing regulatory change to minimize potential adverse impacts to NASA programs and facilities. This presentation highlights the process utilized by the RRACPC to communicate regulatory change and the associated

  3. Balanced Integrated Regulatory Oversight

    International Nuclear Information System (INIS)

    Reactor safety, protecting the public health and safety, and protecting the environment must always be the nuclear regulator's top priorities. Enabling the use of nuclear power for the benefit of society, while protecting the public and the environment requires the regulator to balance many factors. In addition, the regulator is only one part of the overall government that must consider many factors as it carries out its societal responsibilities. Some of the factors that must be balanced and the practical impacts on how the regulator carries out its responsibilities will be addressed. The first International Conference on Effective Regulatory Systems, held in Moscow, Russian Federation, in 2006, focused on safety and security challenges with a goal of improving regulatory effectiveness through cooperation and sharing of information and best practices. The challenge of meeting both safety and security objectives is one example of potentially competing programmes that must be balanced. Other balances that must be evaluated include the benefits of safety improvements compared to the cost of implementation, the use of deterministic and probabilistic approaches, communication openness balanced with the protection of information that could be used for detrimental purposes, and timeliness of regulatory decision making balanced with the need to perform quality work in support of oversight responsibilities. A balanced and integrated approach to regulatory oversight is vital to ensuring that the regulatory body remains effective in its mission to enable the use of nuclear power while protecting the public and the environment. This concept is applicable to nations beginning a nuclear programme as well as established and experienced regulatory bodies. (author)

    1997-02-01

    The author provides an outline which touches on the types of concerns about risk evaluation which are addressed in the process of establishing regulatory guides. Broadly he says regulatory activity serves three broad constituents: (1) Paternalism (private risk); (2) Promotion of social welfare (public risks); (3) Protection of individual rights (public risks). He then discusses some of the major issues encountered in reaching a decision on what is an acceptable level of risk within each of these areas, and how one establishes such a level.

  5. Regulatory Issues Surrounding Merchant Interconnection

    International Nuclear Information System (INIS)

    We discussed various issues concerning the regulatory perspective on private investment in interconnectors. One might claim that leaving investment in transmission infrastructure to competing market parties is more efficient than relying on regulated investment only (especially in the case of long (DC) lines connecting previously unconnected parts of the grids, so that externalities from e.g. loop flows do not play a significant role). We considered that some aspects of interconnection might reduce these market benefits. In particular, the large fixed costs of interconnection construction may lead to significant under investment (due to both first mover monopoly power and the fact that part of generation cost efficiencies realised by interconnection are not captured by the investor itself, and remain external to the investment decision). Second, merchant ownership restricts future opportunities for adaptation of regulation, as would be required e.g. for introduction of potentially more sophisticated methods of congestion management or market splitting. Some of the disadvantages of merchant investment may be mitigated however by a suitable regulatory framework, and we discussed some views in this direction. The issues we discussed are not intended to give a complete framework, and detailed regulation will certainly involve many more specific requirements. Areas we did not touch upon include e.g. the treatment of deep connection costs, rules for operation and maintenance of the line, and impact on availability of capacity on other interconnections

  14. Regulatory and operating experience

    International Nuclear Information System (INIS)

    Regulatory and operating experience in the disposal of radioactive waste can be divided into three time periods, World War II and its aftermath, Post World War II till the end of the cold war, and crystal ball gazing into the future. In the first period, there was little regulatory guidance and operating practices, all conducted under wartime secrecy conditions, sometimes were not even up to the norms of the times. Environmental releases resulted in some seriously contaminated sites and high dosages to some offsite populations. Failure to consider even the storage of wastes in a systems context resulted in some stocks that were difficult to recover, treat and dispose of in a final manner. In the second period, increasing civilian uses of nuclear power and isotopes for medical, research, and industrial purposes and military pressure for increased production of Pu-239 resulted in large and more dispersed disposal of radioactive wastes. Regulatory regimes, following growing environmental consciousness, came into existence that minimized exposure to environmental contamination. Practices, in most instances, increasingly conformed to these regulatory demands. The future is unknowable. However, for high level wastes, except for thermodynamically stable forms, no technology can guarantee safety and present methodologies are calculated to produce doses orders of magnitude lower than regulatory limits. Therefore, it is possible that research will be limited to no higher technology than is reasonably achievable. Whereas for low level waste, where proof is practicably possible, as high technology as is reasonably achievable will be best in the long run. (author). 24 refs, 5 figs, 3 tabs

  19. A flexible regulatory framework

    International Nuclear Information System (INIS)

    Regulatory reform of the Finnish electricity market meant opening up potentially competitive parts of the electricity sector to competition and eliminating all unnecessary forms of regulation covering generation, wholesale supply, retail supply, and foreign trade in electricity. New types of control and regulatory mechanisms and institutions were set up for those parts of the electricity industry that were excluded from competition, such as network operations. Network activities now have to be licensed, whereas no licence is needed for generation or supply. A new sector-specific regulatory authority was established in 1995 to coincide with the implementation of the Electricity Market Act, known as the Electricity Market Authority. This is responsible for regulating network activities and retail supply to captive customers. The core function of the authority, which employs some 14 people, is to promote the smooth operation of the Finnish electricity market and to oversee the implementation of the Electricity Market Act and its provisions. Its most important duties are linked to overseeing the process by which network companies price their electricity. As price regulation no longer exists, all the companies in the electricity sector set their tariffs independently, even network companies. The job of controlling the pricing of network services is handed by the Electricity Market Authority, following the principles of competition control. Pricing control takes place ex post - after a pricing system has been adopted by a company and concentrates on individual cases and companies. There is no ex ante system of setting or approving prices and tariffs by the regulator. The tariffs and pricing of network services can be evaluated, however, by both the Electricity Market Authority and the Finnish Competition Authority, which have overlapping powers as regards the pricing of network activities. The Finnish regulatory framework can be described as a system of light

  1. The changing regulatory environment

    International Nuclear Information System (INIS)

    The role and value of regulation in the energy sector was discussed, demonstrating how, despite common perception, regulation is an essential part of Canada's strategy to find and develop new opportunities. The future vision of regulation for industry participants was presented with particular focus on issues related to streamlining the regulatory process. As far as pipelines are concerned, regulatory actions are necessary to facilitate capacity increases and to ensure the line's integrity, safety and environmental record. Furthermore, regulation provides economic solutions where market forces cannot provide them, as for example where business has elements of monopoly. It arbitrates interests of landowners, business, consumers, and environmental groups. It looks for ways to ensure conditions under which competition can flourish. It acts as the guardian of citizens' rights in a democratic society by providing citizens with an opportunity to be heard on the building or expansion of pipelines and associated facilities. As citizens become more and more concerned about their property and the land that surrounds them, citizen involvement in decision making about how industry activity affects their quality of life will become correspondingly more important. Regulatory agencies are committed to facilitate this engagement by flexible hearing procedures and by making use of evolving communication and information technology

    Nanomedicines have been in the forefront of pharmaceutical research in the last decades, creating new challenges for research community, industry, and regulators. There is a strong demand for the fast development of scientific and technological tools to address unmet medical needs, thus improving human health care and life quality. Tremendous advances in the biomaterials and nanotechnology fields have prompted their use as promising tools to overcome important drawbacks, mostly associated to the non-specific effects of conventional therapeutic approaches. However, the wide range of application of nanomedicines demands a profound knowledge and characterization of these complex products. Their properties need to be extensively understood to avoid unpredicted effects on patients, such as potential immune reactivity. Research policy and alliances have been bringing together scientists, regulators, industry, and, more frequently in recent years, patient representatives and patient advocacy institutions. In order to successfully enhance the development of new technologies, improved strategies for research-based corporate organizations, more integrated research tools dealing with appropriate translational requirements aiming at clinical development, and proactive regulatory policies are essential in the near future. This review focuses on the most important aspects currently recognized as key factors for the regulation of nanomedicines, discussing the efforts under development by industry and regulatory agencies to promote their translation into the market. Regulatory Science aspects driving a faster and safer development of nanomedicines will be a central issue for the next years. PMID:26260323

  3. Hastening the regulatory process

    International Nuclear Information System (INIS)

    The state of the Canadian oil industry was discussed during this power point presentation with particular emphasis on its production, exports, drilling, industry revenues and capital investment levels. The proposed projects in each of northern Alberta's oil sands deposits, the Athabasca, Peace River and Cold Lake were were announced, along with the inventory of major Alberta projects and the projection of oil sands capital investment. Since 1998, $9 billion has been invested and a further $33 billion has been announced for new or expanded oil sands projects. The year 2000 estimates for Canadian crude oil and natural gas production are 2.3 million barrels per day and 6.3 trillion cubic feet per year respectively. This represented a record year for production of both crude oil and natural gas. In 2000, more than 15,500 wells were drilled in Canada. A graph depicting Canadian crude oil supply forecasted a steady increase in supply from year 2000 to 2010. The Canadian Association of Petroleum Producers (CAPP) completed a review of the Alberta Energy and Utilities Board regulatory and enforcement processes. Both industry and government efforts are focusing on eliminating regulatory overlap and duplication. Some of the main areas of interest for exploration, drilling, production and pipeline facilities include the examination of regulatory processes for environmentally sensitive areas, rural municipalities with planning bylaws, aboriginal lands and additional fees. 8 figs

    Restricted access to electricity, the existence of an energy matrix based on fossil fueled electricity plants and the lack of financial means by the population living in the Northern region of Brazil to afford the costs with electricity generation, transmission and distribution in the region created the need to implement cross subsidies in the country's electric sector isolated system. The subsidy policies have aimed at allowing the access to electricity for the population and industries in the north of Brazil and at promoting the economic development of this region, but have brought a great cost to society, particularly the Fuel Consumption Account (CCC), considering the environmental impacts of the fossil fuel use. This paper evaluates the current structure and the regulatory norms of the electricity sector's subsidies granted to the Isolated Systems, and intend to propose measures to reduce emissions of greenhouse gases in the thermoelectric generation plants in the isolated systems with the implementation of governmental incentives to power plants efficiency.

  6. Schedules for Regulatory Regimes

    International Nuclear Information System (INIS)

    The idea of regulating transporters' terms of operations is that if the market itself does not produce optimal outcomes, then it can be mimicked to do so through regulatory and other public instruments. The first-best solution could be a subsidized (publicly owned) enterprise that sets tariffs according to marginal costs. This has been the tradition in many European countries in the aftermath of WW2. Due to lack of innovative pressure on and x-inefficiency in these companies, this solution is today viewed as inferior to the system of regulating independent (privately owned) firms. When the European gas market becomes liberalized, part of the process in many countries is to (partially) privatise the transport utilities. Privatised or not, in a liberalized market, the transport utilities should face an independent authority that overviews their operations not only in technical, but also in economic terms. Under regulation, a ''visible hand'' is introduced to correct the imperfect market's ''invisible hand''. By regulating the framework and conditions for how firms may operate, public authorities seek to achieve what is considered optimal for the society. The incentives and disincentives given for pricing and production should create mechanisms leading to an efficient allocation of resources and ''acceptable'' distribution of income. As part of intervening into firms' behavior, regulation may be introduced to direct the firm to behave in certain ways. The framework and regulatory mechanisms for the market must then be constructed in a way that companies voluntarily produce an amount at a price that gives maximal profits and simultaneously satisfies social goals. The regulations should lead to consistency between the company's desire to maximize profits and the society's desire for maximizing welfare, as in a perfectly competitive market. This is the core of regulatory economics

  8. The core to regulatory reform

    International Nuclear Information System (INIS)

    Federal Energy Regulatory Commission (FERC) Orders 436, 500, and 636, the Clean Air Act Amendments of 1990, Public Utility Holding Company Act reform, and the 1992 Energy Policy Act all can have significant effects on an LDC's operations. Such changes in an LDC's environments must be balanced by changes within the utility, its marketplace, and its state regulatory environment. The question is where to start. For Columbia Gas Distribution Cos., based in Columbus, OH, the new operating foundation begins with each employee. Internal strength is critical in designing initiatives that meet the needs of the marketplace and are well-received by regulators. Employees must understand not only the regulatory environment in which the LDC operates, but also how their work contributes to a positive regulatory relationship. To achieve this, Columbia initiated the COntinuing Regulatory Education program, or CORE, in 1991. CORE is a regulatory-focused, information-initiative program coordinated by Columbia's Regulatory Policy, Planning, and Government Affairs Department. The CORE programs can take many forms, such as emerging issue discussions, dialogues with regulators and key parties, updates on regulatory fillings, regulatory policy meetings, and formal training classes. The speakers and discussion facilitators can range from human resource department trainers to senior officers, from regulatory department staff members to external experts, or from state commissioners to executives from other LDCs. The goals of CORE initiatives are to: Support a professional level of regulatory expertise through employee participation in well-developed regulatory programs presented by credible experts. Encourage a constructive state regulatory environment founded on communication and cooperation. CORE achieves these goals via five program levels: introductory basics, advanced learning, professional expertise, crossfunctional dialogues, and external idea exchanges

  9. The regulatory dynamic

    International Nuclear Information System (INIS)

    An outline of the activities and efforts expanded by the National Energy Board to adjust to the changing natural gas market was provided in this presentation. The author began by defining the role of the National Energy Board in energy markets. It must ensure the adoption of rules and procedures that result in a more competitive and efficient market. Light-handed regulatory techniques are the norm, and the National Energy Board is now committed to facilitating the availability and flow of information so that all parties know where opportunities exist, the terms offered to buy or sell goods and services, their quality and costs. It will specialize in providing new participants with information on the workings of the market, who the players are, the regulatory processes in place, and how, when and where the market can be accessed. The manner in which the Board deals with information was reviewed, providing examples along the way to clarify some points. Some of the documents produced by the National Energy Board are being reviewed with the intent of making them easier to read and understand. Audio streaming over the Internet is another avenue being pursued to ensure individuals can listen in real time to hearings without having to be present in the room. The National Energy Board is also exploring alternative dispute resolution techniques. Consultation with energy market participants represents another facet of these efforts to be more accessible and responsive

  10. Visions of regulatory renewal

    International Nuclear Information System (INIS)

    The economic contribution of the CEPA (Canadian Energy Pipeline Association) member companies to Canada's trade balance was discussed. CEPA member companies transport 95 per cent of the crude oil and natural gas produced in Canada to domestic and export markets. This represents a total of 5.6 Tcf of gas annually. Half of Canada's natural gas and oil production is exported to U.S. markets. All of these exports are transported by pipeline. CEPA member companies operate 90,000 km of pipeline from British Columbia to Quebec. Expansions are needed as a result of a significant increase in demand for natural gas and crude oil since 1990. Several issues exist for regulatory renewal. They include the need to create a level playing field, the overseeing of tolls and contract renewal terms, changing risk/reward trade-offs, the right to confidentiality of information and price discovery mechanism. The drivers for regulatory reform at Westcoast Energy are the need for pricing flexibility, customers desire for toll certainty, decontracting and opposition to rolled-in expansions for gathering and processing. An overview of Westcoast Energy's negotiated toll settlement, its implications, and the components of Westcoast Energy's 'light handed regulation' (LHR) was presented

  11. Assessment of regulatory effectiveness. Peer discussions on regulatory practices

    International Nuclear Information System (INIS)

    This report arises from the seventh series of peer discussions on regulatory practices entitled 'Assessment of Regulatory Effectiveness'. The term 'regulatory effectiveness' covers the quality of the work and level of performance of a regulatory body. In this sense, regulatory effectiveness applies to regulatory body activities aimed at preventing safety degradation and ensuring that an acceptable level of safety is being maintained by the regulated operating organizations. In addition, regulatory effectiveness encompasses the promotion of safety improvements, the timely and cost effective performance of regulatory functions in a manner which ensures the confidence of the operating organizations, the general public and the government, and striving for continuous improvements to performance. Senior regulators from 22 Member States participated in two peer group discussions during March and May 1999. The discussions were focused on the elements of an effective regulatory body, possible indicators of regulatory effectiveness and its assessment. This report presents the outcome of these meetings and recommendations of good practices identified by senior regulators, which do not necessarily reflect those of the governments of the nominating Member States, the organizations they belong to, or the International Atomic Energy Agency. In order to protect people and the environment from hazards associated with nuclear facilities, the main objective of a nuclear regulatory body is to ensure that a high level of safety in the nuclear activities under its jurisdiction is achieved, maintained and within the control of operating organizations. Even if it is possible to directly judge objective safety levels at nuclear facilities, such safety levels would not provide an exclusive indicator of regulatory effectiveness. The way the regulatory body ensures the safety of workers and the public and the way it discharges its responsibilities also determine its effectiveness. Hence the

    Although many regulatory networks involved in defining definitive endoderm have been identified, the mechanisms through which these networks interact to pattern the endoderm are less well understood. To explore the mechanisms involved in midgut patterning, we dissected the transcriptional regulatory elements of nephrocan (Nepn), the earliest known midgut specific gene in mice. We observed that Nepn expression is dramatically reduced in Sox17−/− and Raldh2−/− embryos compared with wild-type em...

    This chapter is based on a work performed in distinct phases. The first phase consisted in of the analysis regulatory legislation existent in Brazil for the sugar-alcohol sector since the beginning of the X X century. This analysis allowed the identification of non existent points and legal devices related to the studied aspects, and that were considered as problematic for the sector expansion. In the second phase, related treaties and international agreements was studied and possible obstacles for the brazilian bio ethanol exportation for the international market. Initiatives were examined at European Union, United States of America, Caribbean and countries of the sub-Saharan Africa. In this phase, policies were identified related to the incentives and adoption of use of bio fuels added to the gasoline in countries or group of countries considered as key for the consolidation of bio ethanol as a world commodity.

    International Nuclear Information System (INIS)

    This is the thirty-sixth volume of issuances (1-396) of the Nuclear Regulatory Commission and its Atomic Safety and Licensing Boards, Administrative Law Judges, and Office Directors. It covers the period from July 1, 1992-December 31, 1992. Atomic Safety and Licensing Boards are authorized by Section 191 of the Atomic Energy Act of 1954. These Boards, comprised of three members conduct adjudicatory hearings on applications to construct and operate nuclear power plants and related facilities and issue initial decisions which, subject to internal review and appellate procedures, become the final Commission action with respect to those applications. Boards are drawn from the Atomic Safety and Licensing Board Panel, comprised of lawyers, nuclear physicists and engineers, environmentalists, chemists, and economists. The Atomic Energy Commission first established Licensing Boards in 1962 and the Panel in 1967

    Science.gov (United States)

    Hayne, Cheryl L; Moran, Patricia A; Ford, Mary M

    2004-01-01

    The marked increase in the prevalence of obesity appears to be attributable to environmental conditions that implicitly discourage physical activity while explicitly encouraging the consumption of greater quantities of energy-dense, low-nutrient foods. In the United States food environment, consumers are bombarded with advertising for unhealthy food, and receive inadequate nutritional information, especially at restaurants. In the US school environment children have access to sugary sodas and unhealthy a la carte foods in their cafeterias, at the same time getting inadequate physical activity and nutrition education. In the built environment, sprawl has reduced active living. We describe these environments and explore the potential effects of regulatory measures on these environments. In the United States, regulatory opportunities exist at the national, state and local levels to mandate action and to allocate funds for promising health-promoting strategies. Regulatory approaches, much like litigation, can transform the entire environment in which corporations operate. Even with incomplete enforcement of rules, they send a public message about what is acceptable behavior for corporations and individuals. Additionally, because the United States is party to many multilateral and bilateral trade agreements and is an active participant in the GATT/WTO framework, US regulatory actions promise to have a beneficial impact both domestically and globally.

    Sage, Peter T; Sharpe, Arlene H

    2016-05-01

    Pathogen exposure elicits production of high-affinity antibodies stimulated by T follicular helper (Tfh) cells in the germinal center reaction. Tfh cells provide both costimulation and stimulatory cytokines to B cells to facilitate affinity maturation, class switch recombination, and plasma cell differentiation within the germinal center. Under normal circumstances, the germinal center reaction results in antibodies that precisely target foreign pathogens while limiting autoimmunity and excessive inflammation. In order to have this degree of control, the immune system ensures Tfh-mediated B-cell help is regulated locally in the germinal center. The recently identified T follicular regulatory (Tfr) cell subset can migrate to the germinal center and inhibit Tfh-mediated B-cell activation and antibody production. Although many aspects of Tfr cell biology are still unclear, recent data have begun to delineate the specialized roles of Tfr cells in controlling the germinal center reaction. Here we discuss the current understanding of Tfr-cell differentiation and function and how this knowledge is providing new insights into the dynamic regulation of germinal centers, and suggesting more efficacious vaccine strategies and ways to treat antibody-mediated diseases.

  2. International Collaboration on Regulatory Supervision

    International Nuclear Information System (INIS)

    This paper describes the Norwegian Radiation Protection Authority's experience in regulatory cooperation projects in Russia, with special focus on legacy issues. These legacies include large waste sources, such as those used in radioisotope thermoelectric generators, and remediation of former military sites used for storage of spent nuclear fuel and radioactive waste. The objectives of the cooperation programme are to promote effective and efficient regulatory supervision, taking into account international recommendations and good practice in other countries. Specific projects in the program address specific challenges which require practical local interpretation of ICRP recommendations, the IAEA Basic Safety Standards and other IAEA requirements and guidance documents. In some cases, new regulatory documentation has been required, as well as new regulatory procedures. In the long term, the program is intended to lead to an enhanced and enduring safety culture. The positive experience in Russia has encouraged the Norwegian government in 2008 to extend the regulatory collaboration programme to countries in central Asia, using experience gained with Russian regulatory authorities as well as support from Russian Technical Support Organisations. The programmes are evolving into a regional regulatory support group. Noting this experience, the paper includes suggestions and ideas for how such regional groups can be effective in addressing common radiation safety objectives while addressing local differences in technical, geographical, economic and cultural matters in each country.

  3. Enhancing NRC's regulatory oversight by considering costs

    International Nuclear Information System (INIS)

    Nuclear power plant licensees have resource constraints in the conduct of their operations as does the U.S. Nuclear Regulatory Commission (NRC) staff in the conduct of its function of regulatory review and oversight of electrical generating nuclear power plants. Prioritization of the workload is a necessary part of managing both activities. Traditionally, the staff determines the priority for a task on the basis of the safety significance to the affected facility. Recent experience has shown that, because of the resource constraints, many of the actions requested of the NRC experience long delays in being resolved because they do not pass the NRC's threshold for short-term actions. The NRC management has decided that those actions that can reduce licensee costs without adversely affecting safety should receive a higher priority staff review and closure. The NRC is taking this action in response to information from the industry that operation and maintenance costs are increasing inordinately without a commensurate improvement in plant safety. The Office of Nuclear Reactor Regulation, which has primary licensing responsibility, has set up a task group to identify the cost-beneficial licensing actions that are awaiting regulatory review, recommend a process to conduct the review, and provide a timely safety evaluation report that can serve as the basis for licensees to proceed with their proposed actions if the staff finds the proposed action justifiable under the regulations

  4. Carbon Capture and Storage Legal and Regulatory Review. Edition 3

    Energy Technology Data Exchange (ETDEWEB)

    2012-07-01

    The International Energy Agency (IEA) considers carbon capture and storage (CCS) a crucial part of worldwide efforts to limit global warming by reducing greenhouse-gas emissions. The IEA estimates that emissions can be reduced to a level consistent with a 2°C global temperature increase through the broad deployment of low-carbon energy technologies – and that CCS would contribute about one-fifth of emission reductions in this scenario. Achieving this level of deployment will require that regulatory frameworks – or rather a lack thereof – do not unnecessarily impede environmentally safe demonstration and deployment of CCS, so in October 2010 the IEA launched the IEA Carbon Capture and Storage Legal and Regulatory Review. The CCS Review is a regular review of CCS regulatory progress worldwide. Produced annually, it collates contributions by national and regional governments, as well as leading organisations engaged in CCS regulatory activities, to provide a knowledge-sharing forum to support CCS framework development. Each two page contribution provides a short summary of recent and anticipated CCS regulatory developments and highlights a particular, pre-nominated regulatory theme. To introduce each edition, the IEA provides a brief analysis of key advances and trends, based on the contributions submitted. The theme for this third edition is stakeholder engagement in the development of CO2 storage projects. Other issues addressed include: regulating CO2-EOR, CCS and CO2-EOR for storage; CCS incentive policy; key, substantive issues being addressed by jurisdictions taking steps to finalise CCS regulatory framework development; and CCS legal and regulatory developments in the context of the Clean Energy Ministerial Carbon Capture, Use and Storage Action Group.

    International Nuclear Information System (INIS)

    The present paper discusses briefly the many factors, including capital cost, which have to be taken into account in determining whether a series of power stations based on a small nuclear plant can be competitive with a series based on traditional large unit sizes giving the guaranteed level of supply. The 320 MWe UK/US Safe Integral Reactor is described as a good example of how the factors discussed can be beneficially incorporated into a design using proven technology. Finally it goes on to illustrate how the overall costs of a generating system can indeed by reduced by use of the 320 MWe Safe Integral Reactor rather than conventional units of around 1200 MWe.

When these quality assurance publications were developed, their prime focus was on requirements against which work performed by the licensees could be measured and assessed by the regulatory bodies. In this way, they only helped to facilitate the functions of regulators. No requirements or recommendations were provided on how the regulators should ensure the effective implementation of their own activities. The present publication is a first attempt to collect, integrate and offer available experience to directly support performance of regulatory activities. It presents a comprehensive compilation on the application of quality assurance principles and methods by regulatory bodies to their activities. The aim is consistent good performance of regulatory activities through a systematic approach

    Truthful revelation mechanisms with auditing have the undesirable property that audits are not actually performed in equilibrium because all inference problems have been solved. A model is proposed in which the inference problem is preserved by separating the regulatory and auditing functions and transfers are costly. The auditor designs a Bayesian audit procedure and the regulator credibly commits to using this procedure in the regulatory mechanism. The auditor is conservative, that is, he d...

    Johnson, Branden B; Finkel, Adam M

    2016-06-01

    Public perceptions of both risks and regulatory costs shape rational regulatory choices. Despite decades of risk perception studies, this article is the first on regulatory cost perceptions. A survey of 744 U.S. residents probed: (1) How knowledgeable are laypeople about regulatory costs incurred to reduce risks? (2) Do laypeople see official estimates of cost and benefit (lives saved) as accurate? (3) (How) do preferences for hypothetical regulations change when mean-preserving spreads of uncertainty replace certain cost or benefit? and (4) (How) do preferences change when unequal interindividual distributions of hypothetical regulatory costs replace equal distributions? Respondents overestimated costs of regulatory compliance, while assuming agencies underestimate costs. Most assumed agency estimates of benefits are accurate; a third believed both cost and benefit estimates are accurate. Cost and benefit estimates presented without uncertainty were slightly preferred to those surrounded by "narrow uncertainty" (a range of costs or lives entirely within a personally-calibrated zone without clear acceptance or rejection of tradeoffs). Certain estimates were more preferred than "wide uncertainty" (a range of agency estimates extending beyond these personal bounds, thus posing a gamble between favored and unacceptable tradeoffs), particularly for costs as opposed to benefits (but even for costs a quarter of respondents preferred wide uncertainty to certainty). Agency-acknowledged uncertainty in general elicited mixed judgments of honesty and trustworthiness. People preferred egalitarian distributions of regulatory costs, despite skewed actual cost distributions, and preferred progressive cost distributions (the rich pay a greater than proportional share) to regressive ones. Efficient and socially responsive regulations require disclosure of much more information about regulatory costs and risks. PMID:26742683

    Transforming growth factor beta (TGFβ) signalling is critical for regulatory T cell development and function, and regulatory T cell dysregulation is a common observation in autoimmune diseases, including multiple sclerosis. In a comprehensive miRNA profiling study of patients with multiple sclerosis naïve CD4 T cells, 19 differentially expressed miRNAs predicted to target the TGFβ signalling pathway were identified, leading to the hypothesis that miRNAs may be responsible for the regulatory T cell defect observed in patients with multiple sclerosis. Patients with multiple sclerosis had reduced levels of TGFβ signalling components in their naïve CD4 T cells. The differentially expressed miRNAs negatively regulated the TGFβ pathway, resulting in a reduced capacity of naïve CD4 T cells to differentiate into regulatory T cells. Interestingly, the limited number of regulatory T cells, that did develop when these TGFβ-targeting miRNAs were overexpressed, were capable of suppressing effector T cells. As it has previously been demonstrated that compromising TGFβ signalling results in a reduced regulatory T cell repertoire insufficient to control autoimmunity, and patients with multiple sclerosis have a reduced regulatory T cell repertoire, these data indicate that the elevated expression of multiple TGFβ-targeting miRNAs in naïve CD4 T cells of patients with multiple sclerosis impairs TGFβ signalling, and dampens regulatory T cell development, thereby enhancing susceptibility to developing multiple sclerosis.

  6. Regulatory Expectations for Safety Culture

    International Nuclear Information System (INIS)

    The oversight of licensee's safety culture becomes an important issue that attracts great public and political concerns recently in Korea. Beginning from the intended violation of rules, a series of corruptions, documents forgery and disclosure of wrong-doings made the public think that the whole mindset of nuclear workers has been inadequate. Thus, they are demanding that safety culture shall be improved and that regulatory body shall play more roles and responsibilities for the improvements and oversight for them. This paper introduces, as an effort of regulatory side, recent changes in the role of regulators in safety culture, regulatory expectations on the desired status of licensee's safety culture, the pilot inspection program for safety culture and research activity for the development of oversight system. After the Fukushima accident in Japan 2011, many critics has searched for cultural factors that caused the unacceptable negligence pervaded in Japan nuclear society and the renewed emphasis has been placed on rebuilding safety culture by operators, regulators, and relevant institutions globally. Significant progress has been made in how to approach safety culture and led to a new perspective different from the existing normative assessment method both in operators and regulatory side. Regulatory expectations and oversight of them are based on such a new holistic concept for human, organizational and cultural elements to maintain and strengthen the integrity of defense in depth and consequently nuclear safety

  7. Regulatory physiology discipline science plan

    Science.gov (United States)

    1991-01-01

    The focus of the Regulatory Physiology discipline of the Space Physiology and Countermeasures Program is twofold. First, to determine and study how microgravity and associated factors of space flight affect the regulatory mechanisms by which humans adapt and achieve homeostasis and thereby regulate their ability to respond to internal and external signals; and, second, to study selected physiological systems that have been demonstrated to be influenced by gravity. The Regulatory Physiology discipline, as defined here, is composed of seven subdisciplines: (1) Circadian Rhythms, (2) Endocrinology, (3) Fluid and Electrolyte Regulation, (4) Hematology, (5) Immunology, (6) Metabolism and Nutrition, and (7) Temperature Regulation. The purpose of this Discipline Science Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the area of regulatory physiology. It covers the research areas critical to NASA's programmatic requirements for the Extended-Duration Orbiter, Space Station Freedom, and exploration mission science activities. These science activities include ground-based and flight; basic, applied, and operational; and animal and human research and development. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, identifies science priorities, and defines critical questions in regulatory physiology. It contains a general plan that will be used by both NASA Headquarters Program Offices and the field centers to review and plan basic, applied, and operational intramural and extramural research and development activities in this area.

    Jeong, M; Goodell, M A

    2016-01-01

    Hematopoiesis is a dynamic process in which blood cells are continuously generated from hematopoietic stem cells (HSCs). The regulatory mechanisms controlling HSC fate have been studied extensively over the past several decades. Although many protein-coding genes have been shown to regulate hematopoietic differentiation, additional levels of HSC regulation are not well studied. Advances in deep sequencing have revealed many new classes of regulatory noncoding RNAs (ncRNAs), such as enhancer RNAs and antisense ncRNAs. Functional analysis of some of these ncRNAs has provided insights into the molecular mechanisms that regulate hematopoietic development and disease. In this review, we summarize recent advances in our understanding of functional regulatory ncRNAs associated with hematopoietic self-renewal and differentiation, as well as those dysregulated ncRNAs involved in hematologic malignancies.

  10. Transparency of nuclear regulatory activities

    International Nuclear Information System (INIS)

    One of the main missions of nuclear regulators is to protect the public, and this cannot be completely achieved without public confidence. The more a regulatory process is transparent, the more such confidence will grow. Despite important cultural differences across countries, a number of common features characterise media and public expectations regarding any activity with an associated risk. A common understanding of transparency and main stakeholders' expectations in the field of nuclear safety were identified during this workshop, together with a number of conditions and practices aimed at improving the transparency of nuclear regulatory activities. These conditions and practices are described herein, and will be of particular interest to all those working in the nuclear regulatory field. Their implementation may, however, differ from one country to another depending on national context. (authors)

  11. Regulatory authority infrastructure for Namibia

    International Nuclear Information System (INIS)

    The Republic of Namibia is participating in the International Atomic Energy Agency's Model Project for the Improvement of National Regulatory Authority Infrastructures in Member States. The paper illustrates our experience in solving problems and difficulties confronted in establishing an effective regulatory authority operating within the existing national infrastructure that should be supported by the Government. An effective regulatory authority is seen as part of the wider administrative scope of our Government through ministerial mandates given by the State from time to time, guaranteeing its independence when implementing legal provisions under statutes. Sections of the report illustrate our experience in the following areas: 1. National radiation protection policy 2. Structure of our national regulatory authority 3. Laws and regulations 4. Provisions for notification, authorization and registration 5. In-depth security measures for radiation sources and radioactive material 6. Systems for the inspection of radiation sources, radioactive materials, enforcement of legal provisions 7. Extent of the applications of radiation sources and radioactive materials in the country. The paper provides information regarding existing Government policy on radiation protection; structure and legal aspects of the national regulatory, including statutes and regulations; the extent of application and uses of radiation sources and security of radioactive materials; human resources: strengths and constraints; management practices and financing of regulatory authority; and plans for emergency recovery of orphan sources. National plans for management of disused sources, recovery of orphan sources, abnormal emergencies, communication of information to affected persons on exposure effects, and the safety training of persons using these applications are discussed. the paper provides a summary and some suggestions of the way forward for Namibia.

  12. Negative cooperativity in regulatory enzymes.

    Levitzki, A; Koshland, D E

    1969-04-01

    Negative cooperativity has been observed in CTP synthetase, an allosteric enzyme which contains a regulatory site. Thus, the same enzyme exhibits negative cooperativity for GTP (an effector) and glutamine (a substrate) and positive cooperativity for ATP and UTP (both substrates). In the process of the delineation of these phenomena, diagnostic procedures for negative cooperativity were developed. Application of these procedures to other enzymes indicates that negative cooperativity is a characteristic of many of them. These findings add strong support for the sequential model of subunit interactions which postulates that ligand-induced conformational changes are responsible for regulatory and cooperative phenomena in enzymes.

  14. DOE regulatory reform initiative vitrified mixed waste

    International Nuclear Information System (INIS)

    The US Department of Energy (DOE) is charged with responsibly managing the largest volume of mixed waste in the United States. This responsibility includes managing waste in compliance with all applicable Federal and State laws and regulations, and in a cost-effective, environmentally responsible manner. Managing certain treated mixed wastes in Resource Conservation and Recovery Act (RCRA) permitted storage and disposal units (specifically those mixed wastes that pose low risks from the hazardous component) is unlikely to provide additional protection to human health and the environment beyond that afforded by managing these wastes in storage and disposal units subject to requirements for radiological control. In October, 1995, the DOE submitted a regulatory reform proposal to the Environmental Protection Agency (EPA) relating to vitrified mixed waste forms. The technical proposal supports a regulatory strategy that would allow vitrified mixed waste forms treated through a permit or other environmental compliance mechanism to be granted an exemption from RCRA hazardous waste regulation, after treatment, based upon the inherent destruction and immobilization capabilities of vitrification technology. The vitrified waste form will meet, or exceed the performance criteria of the Environmental Assessment (EA) glass that has been accepted as an international standard for immobilizing radioactive waste components and the LDR treatment standards for inorganics and metals for controlling hazardous constituents. The proposal further provides that vitrified mixed waste would be responsibly managed under the Atomic Energy Act (AEA) while reducing overall costs. Full regulatory authority by the EPA or a State would be maintained until an acceptable vitrified mixed waste form, protective of human health and the environment, is produced

  15. Regulatory concern about economic deregulation in Finland

    International Nuclear Information System (INIS)

    The deregulation of the electricity market may cause an increased pressure to reduce the costs of electricity generation. This makes a new challenge to the regulatory body to assess the impact of these changes on the safety of nuclear power plants. Accordingly, it is important to identify the risks to the nuclear power industry resulting from the economic deregulation. This paper is to discuss the current situation in Finland with regard to the economic deregulation of the electricity market and the experiences so far. A common view today is that the number of electricity generating power companies will be reduced in Europe because of tough competition in the electricity market. It is expected that only the biggest companies can stand the consequences of tough competition in electricity prices and the consequential pressure to reduce costs. In order to review the impact of deregulation of the electricity market some relevant points have been discussed in this paper, such as change of ownership of power companies due to the economic pressure, the need to cut costs of the companies by reducing the number of their activities and increasing the efficiency in the remaining activities and/or outsourcing of activities. The need to pursue reduction or delay of planned investments in safety upgrades are discussed as well. (author)

  17. Self-sustained oscillations of complex genomic regulatory networks

    International Nuclear Information System (INIS)

    Recently, self-sustained oscillations in complex networks consisting of non-oscillatory nodes have attracted great interest in diverse natural and social fields. Oscillatory genomic regulatory networks are one of the most typical examples of this kind. Given an oscillatory genomic network, it is important to reveal the central structure generating the oscillation. However, if the network consists of large numbers of genes and interactions, the oscillation generator is deeply hidden in the complicated interactions. We apply the dominant phase-advanced driving path method proposed in Qian et al. (2010) to reduce complex genomic regulatory networks to one-dimensional and unidirectionally linked network graphs where negative regulatory loops are explored to play as the central generators of the oscillations, and oscillation propagation pathways in the complex networks are clearly shown by tree branches radiating from the loops. Based on the above understanding we can control oscillations of genomic networks with high efficiency.

  19. New Medical Practices: A Challenge for Regulatory Bodies

    International Nuclear Information System (INIS)

    The Regulatory Bodies should face the regulation for new medical practices to assess the radiation protection of workers and patients, the safety of the installation and reduce subjectivity in their regulatory decisions. In many cases this could result in adapting or preparing new regulations, developing new licensing requirements and adjusting their regulatory processes. It is known the nuclear regulators difficulty regarding the radiation exposure to patients for medical purposes. So that, in this paper, those topics that could contribute positively for optimizing the radiation exposure to patients, like cooperation with professional societies in general and the medical profession in particular, are analyzed with the aim of proposing new strategies to deal with. Finally, the case of workers is analyzed considering the increase of new medical practice involving radiopharmaceuticals and a proposal for a revision of occupational exposure surveillance to assure their radiological protection is presented.

    2015-01-01

    Biological oncology products are integral to cancer treatment, but their high costs pose challenges to patients, families, providers, and insurers. The introduction of biosimilar agents—molecules that are similar in structure, function, activity, immunogenicity, and safety to the original biological drugs—provide opportunities both to improve healthcare access and outcomes, and to reduce costs. Several international regulatory pathways have been developed to expedite entry of biosimilars into global marketplaces. The first wave of oncology biosimilar use was in Europe and India in 2007. Oncology biosimilars are now widely marketed in several countries in Europe, and in Australia, Japan, China, Russia, India, and South Korea. Their use is emerging worldwide, with the notable exception of the USA, where several regulatory and cost barriers to biosimilar approval exist. In this Review, we discuss oncology biosimilars and summarise their regulatory frameworks, clinical experiences, and safety concerns. PMID:25456378

  1. Regulatory treatment of allowances and compliance costs

    Energy Technology Data Exchange (ETDEWEB)

    Rose, K. [National Regulatory Research Institute, Columbus, OH (United States)

    1993-07-01

    The Clean Air Act Amendments of 1990 (CAAA) established a national emission allowance trading system, a market-based form of environmental regulation designed to reduce and limit sulfur dioxide emissions. However, the allowance trading system is being applied primarily to an economically regulated electric utility industry. The combining of the new form of environmental regulation and economic regulation of electric utilities has raised a number of questions including what the role should be of the federal and state utility regulating commissions and how those actions will affect the decision making process of the utilities and the allowance market. There are several dimensions to the regulatory problems that commissions face. Allowances and utility compliance expenditures have implications for least-cost/IPR (integrated resource planning), prudence review procedures, holding company and multistate utility regulation and ratemaking treatment. The focus of this paper is on the ratemaking treatment. The following topics are covered: ratemaking treatment of allowances and compliance costs; Traditional cost-recovery mechanisms; limitations to the traditional approach; traditional approach and the allowance trading market; market-based cost recovery mechanisms; methods of determining the benchmark; determining the split between ratepayers and the utility; other regulatory approaches; limitations of incentive mechanisms.

  3. Regulatory perspectives of concept assessment

    International Nuclear Information System (INIS)

    The Atomic Energy Control Board is the head agency for the regulatory review of the Assessment of the Canadian Concept for Nuclear Fuel Waste Disposal being done by Atomic Energy of Canada Limited and Ontario Hydro. This paper describes the regulatory perspective of how the Concept Assessment could demonstrate the feasibility of a disposal conforming to regulatory requirements. The long-term aspects of Concept Assessment encourage the use of various predictive techniques for different time scales. Each technique will have a different potential for establishing confidence in the predictions. The predicted performance of a facility during operation should have a very high confidence, as it can be based on standard engineering calculations and the predictions can be validated later by monitoring during operation. The predictions of the transient period following closure of the facility should achieve a medium level of confidence, since they can be based on extrapolations of predictions of operational performance, using models that can be calibrated with monitoring data and with averaged input data derived from natural analog studies. Predictions based on fundamental processes will have a medium level of confidence when made to intermediate times after closure. Long-term predictions using generic or typical input data or Monte Carlo calculations of simplified models will have the least confidence and yet they can still contribute to the confidence that the disposal concept will conform to regulatory requirements

  7. Safety culture competition - expectations of a regulatory authority

    International Nuclear Information System (INIS)

    The accident at the Chernobyl nuclear power station on April 26, 1986 influenced the development of reactor safety and promulgated two basic concepts especially in Germany. On the one hand, extensive measures of in-plant accident management have greatly reduced the so-called residual risk. On the other hand, a comprehensive safety approach has been initiated which comprises the nuclear power plant as a system together with people, technology, and organization and also includes safety culture. In a modern regulatory concept based on the dynamic development of safety, the authority's classical regulatory function of controlling is supplemented by the objective of promoting safety. While preserving the division of responsibilities between the regulatory authority and plant operators, the authority uses 'constructive critical dialog' as a tool to enhance safety. Besides the regulatory assessment of safety culture on the basis of indications or indicators, also the continuous promotion of safety culture in a dialog with plant operators is seen as one of the duties of a regulatory authority. Continued efforts are necessary to maintain the high level of safety culture in German nuclear power plants. Operators are expected to establish a safety management which assigns top priority to safety issues, and which pursues the goal of supervising and promoting safety culture. Developments on the deregulated electricity markets must not lead to safety aspects ranking second to economic aspects. Moreover, also under changed boundary conditions, only the safe operation of nuclear power plants ensures economic viability. (orig.)

  8. Regulatory uncertainty and the associated business risk for emerging technologies

    International Nuclear Information System (INIS)

    An oversight system specifically concerned with nanomaterials should be flexible enough to take into account the unique aspects of individual novel materials and the settings in which they might be used, while recognizing that heretofore unrecognized safety issues may require future modifications. This article considers a question not explicitly considered by the project team: what is the risk that uncertainty over how regulatory oversight will be applied to nanomaterials will delay or block the development of this emerging technology, thereby depriving human health of potential and substantial benefits? An ambiguous regulatory environment could delay the availability of valuable new technology and therapeutics for human health by reducing access to investment capital. Venture capitalists list regulatory uncertainty as a major reason not to invest at all in certain areas. Uncertainty is far more difficult to evaluate than risk, which lends itself to quantitative models and can be factored into projections of return on possible investments. Loss of time has a large impact on investment return. An examination of regulatory case histories suggests that an increase in regulatory resting requirement, where the path is well-defined, is far less costly than a delay of a year or more in achieving product approval and market launch.

  14. Modelling Nonstationary Gene Regulatory Processes

    Directory of Open Access Journals (Sweden)

    Marco Grzegorcyzk

    2010-01-01

    Full Text Available An important objective in systems biology is to infer gene regulatory networks from postgenomic data, and dynamic Bayesian networks have been widely applied as a popular tool to this end. The standard approach for nondiscretised data is restricted to a linear model and a homogeneous Markov chain. Recently, various generalisations based on changepoint processes and free allocation mixture models have been proposed. The former aim to relax the homogeneity assumption, whereas the latter are more flexible and, in principle, more adequate for modelling nonlinear processes. In our paper, we compare both paradigms and discuss theoretical shortcomings of the latter approach. We show that a model based on the changepoint process yields systematically better results than the free allocation model when inferring nonstationary gene regulatory processes from simulated gene expression time series. We further cross-compare the performance of both models on three biological systems: macrophages challenged with viral infection, circadian regulation in Arabidopsis thaliana, and morphogenesis in Drosophila melanogaster.

  15. Compliance. Regulatory policy P-211

    International Nuclear Information System (INIS)

    This regulatory policy describes the basic principles and directives for establishing and conducting the Canadian Nuclear Safety Commission (CNSC) Compliance Program. The program is aimed at securing compliance by regulated persons with regulatory requirements made under the Nuclear Safety and Control Act ('the Act'). The policy applies to persons who are regulated by the CNSC through the Act, regulations and licences, as well as by decisions and orders made under the Act. The policy applies to officers and employees of the CNSC, and its authorized representatives or agents, who are involved in developing and carrying out compliance activities. Compliance, in the context of this policy, means conformity by regulated persons with the legally binding requirements of the Act, and the CNSC regulations, licences, decisions, and orders made under the Act. Compliance activities are CNSC measures of promotion, verification and enforcement aimed at securing compliance by regulated person with the applicable legally binding requirements. (author)

  17. Risk informed safety and regulatory decision making: An NRC perspective

    International Nuclear Information System (INIS)

    To accomplish its mission in the coming years, the United States Nuclear Regulatory Commission (NRC) has established a set of four strategic objectives or performance measures by which it can plan, budget, perform and manage its activities: to maintain safety, to increase regulatory effectiveness and efficiency, to reduce unnecessary regulatory burden, and to increase public confidence. Measures are now being developed to assess the NRC's performance in these areas to communicate with stakeholders and demonstrate accountability for its resources. One of the key strategies for accomplishing the NRC's goals is to risk inform its regulations through the use of probabilistic risk analyses, or PRAs. In making risk informed decisions on changing its regulatory framework, the NRC relies on five key principles, as discussed in NRC Regulatory Guide 1.174: (1) does the change continue to meet current regulations? (2) has defence in depth been appropriately considered? (3) is a sufficient safety margin maintained? (4) are the changes in core damage frequency and large early release frequency small? and (5) how are the impacts of the changes monitored? The NRC has undertaken a number of risk informed initiatives based on the general guidance provided in Regulatory Guide 1.174. The NRC has risk informed initiatives in technical specifications, inservice inspection and testing, the reactor oversight process, relaxation of special treatment requirements, and revisions to technical requirements. As the NRC moves forward with increased use of risk informed techniques, it must also undertake the effort to communicate with stakeholders to receive input and explain its activities. That is why the NRC is conducting mandatory PRA training for staff, holding workshops with industry and the public, and generally reaching out to ensure that its efforts in this area are both visible and understandable. The vision for the final product of this complex process is a regulatory structure or

    We examine the suggestion that if consumers in sufficient numbers are willing to pay the premium to have power generated using low-emission technologies, tax or permit policies become less necessary or stringent. While there are implementation difficulties with this proposal, our purpose is more fundamental: can economics make sense of using preferences as a regulatory instrument? If “green” preferences are exogenously given, to what extent can or should they be regarded as a substitute for o...

  3. Regulatory Office for Network Industries

    International Nuclear Information System (INIS)

    The main goal of the economic regulation of network industries is to ensure a balance between the interests of consumers and investors and to encourage providing high-quality goods and services. The task of the regulatory authority is to protect the interests of consumers against monopolistic behaviour of regulated enterprises. At the same time, the regulatory office has to protect the interests of investors by giving them an opportunity to achieve an adequate return on their investments. And last, but not least, the regulatory office has to provide regulated enterprises with appropriate incentives to make them function in an efficient and effective manner and to guarantee the security of delivery of energies and related services. All this creates an efficient regulatory framework that is capable of attracting the required amount and type of investments. This also means providing third party access to the grids, the opening of energy markets, the un-bundling of accounts according to production, distribution, transmission and other activities and the establishment of a transparent and stable legislative environment for regulated companies, investors and consumers. Otherwise, in the long run consumers may suffer from a serious deterioration of service quality, although in the short run they are protected against increased prices. Under the Act No. 276/2001 Coll. on Regulation of Network Industries and on amendment of some acts the Office for Regulation of Network Industries has been commissioned to implement the main objectives of regulation of network industries. By network industries the Act No. 276/2001 Coll. on Regulation means the following areas: (a) Production, purchase, transit and distribution of electricity; (b) Production, purchase, transit and distribution of gas; (c) Production, purchase and distribution of heat; (d) Water management activities relating to the operation of the public water supply system or the public sewerage system; (e) Water management

    2007-01-01

    Understanding the genetic and molecular mechanisms governing the evolution of morphology is a major challenge in biology. Because most animals share a conserved repertoire of body-building and -patterning genes, morphological diversity appears to evolve primarily through changes in the deployment of these genes during development. The complex expression patterns of developmentally regulated genes are typically controlled by numerous independent cis-regulatory elements (CREs). It has been prop...

  17. FORECAST: Regulatory effects cost analysis software manual -- Version 4.1. Revision 1

    International Nuclear Information System (INIS)

    The FORECAST program was developed to facilitate the preparation of the value-impact portion of NRC regulatory analyses. This PC program integrates the major cost and benefit considerations that may result from a proposed regulatory change. FORECAST automates much of the calculations typically needed in a regulatory analysis and thus reduces the time and labor required to perform these analyses. More importantly, its integrated and consistent treatment of the different value-impact considerations should help assure comprehensiveness, uniformity, and accuracy in the preparation of NRC regulatory analyses. The Current FORECAST Version 4.1 has been upgraded from the previous version and now includes an uncertainty package, an automatic cost escalation package, and other improvements. In addition, it now explicitly addresses public health impacts, occupational health impacts, onsite property damage, and government costs. Thus, FORECAST Version 4.1 can treat all attributes normally quantified in a regulatory analysis

    2013-04-18

    The Decade of Vaccines Collaboration and development of the Global Vaccine Action Plan provides a catalyst and unique opportunity for regulators worldwide to develop and propose a global regulatory science agenda for vaccines. Regulatory oversight is critical to allow access to vaccines that are safe, effective, and of assured quality. Methods used by regulators need to constantly evolve so that scientific and technological advances are applied to address challenges such as new products and technologies, and also to provide an increased understanding of benefits and risks of existing products. Regulatory science builds on high-quality basic research, and encompasses at least two broad categories. First, there is laboratory-based regulatory science. Illustrative examples include development of correlates of immunity; or correlates of safety; or of improved product characterization and potency assays. Included in such science would be tools to standardize assays used for regulatory purposes. Second, there is science to develop regulatory processes. Illustrative examples include adaptive clinical trial designs; or tools to analyze the benefit-risk decision-making process of regulators; or novel pharmacovigilance methodologies. Included in such science would be initiatives to standardize regulatory processes (e.g., definitions of terms for adverse events [AEs] following immunization). The aim of a global regulatory science agenda is to transform current national efforts, mainly by well-resourced regulatory agencies, into a coordinated action plan to support global immunization goals. This article provides examples of how regulatory science has, in the past, contributed to improved access to vaccines, and identifies gaps that could be addressed through a global regulatory science agenda. The article also identifies challenges to implementing a regulatory science agenda and proposes strategies and actions to fill these gaps. A global regulatory science agenda will enable

  19. Food irradiation--US regulatory considerations

    International Nuclear Information System (INIS)

    The use of ionizing radiation in food processing has received increased interest as a means of reducing the level of foodborne pathogens. This overview discusses the regulatory issues connected with the use of this technology in the United States. Several recent changes in the FDA's review process are discussed. These include the current policy that utilizes an expedited review process for petitions seeking approval of additives and technologies intended to reduce pathogen levels in food, and the recent USDA rule that eliminates the need for a separate rulemaking process by USDA for irradiation of meat and poultry. Recently promulgated rules and pending petitions before the FDA associated with the use of ionizing radiation for the treatment of foods are also discussed along with the current FDA labeling requirements for irradiated foods and the 1999 advanced notice of proposed rule on labeling. Another issue that is presented is the current status of the approval of packaging materials intended for food contact during irradiation treatment of foods

Design/methodology/approach – based on current regulatory framework and analysis of academic literature, author discusses problematic issues related to the needs and further perspectives of proactive regulatory regime in EU electronic communications sector. Findings – the author reviews special qualities for different regulatory regimes (ex ante, ex post and examines them in the context of sharp developments of the industry and EU regulatory policy. Research limitations/implications –the analysis aims to convey the main understanding on the regulatory specifics of the communications industry, the main features, distinguishing communications industry from the others and foreseeable regulatory perspectives Practical implications – the core aspect of the paper is to evaluate current regulatory approach of the EU electronic communications sector and assess potential regulatory approaches in the context of making self-sustaining pro-competitive market structure, technological development. Originality/Value – the paper highlights some significant changes between two regulatory approaches in the light of specific features in EU electronic communications. Author provides his insights on the status and perspectives on application for both regulatory methods. Apparently, these issues have so far been subjected too little academic analysis. As shown in this paper, regulatory policy can have the essential impact on the activities taken by other players. The decision to give an even bigger role to competition rules, do not mean to eliminate sector specifics itself. With this in mind, EU legislators are not able to eliminate proactive regulatory control, thus reducing ex ante rules progressively

  1. Probabilistic safety assessment - regulatory perspective

    International Nuclear Information System (INIS)

    Full text: Nuclear power plants (NPPs) have been designed, constructed and operated mainly based on deterministic safety analysis philosophy. In this approach, a substantial amount of safety margin is incorporated in the design and operational requirements. Additional margin is incorporated by applying the highest quality engineering codes, standards and practices, and the concept of defence-in-depth in design and operating procedures, by including conservative assumptions and acceptance criteria in plant response analysis of postulated initiating events (PIEs). However, as the probabilistic approach has been improved and refined over the years, it is possible for the designer, operator and regulator to get a more detailed and realistic picture of the safety importance of plant design features, operating procedures and operational practices by using probabilistic safety assessment (PSA) along with the deterministic methodology. At present, many countries including USA, UK and France are using PSA insights in their decision making along with deterministic basis. India has also made substantial progress in the development of methods for carrying out PSA. However, consensus on the use of PSA in regulatory decision-making has not been achieved yet. This paper emphasises on the requirements (e.g.,level of details, key modelling assumptions, data, modelling aspects, success criteria, sensitivity and uncertainty analysis) for improving the quality and consistency in performance and use of PSA that can facilitate meaningful use of the PSA insights in the regulatory decision-making in India. This paper also provides relevant information on international scenario and various application areas of PSA along with progress made in India. The PSA perspective presented in this paper may help in achieving consensus on the use of PSA for regulatory / utility decision-making in design and operation of NPPs

  2. Wetlands: The changing regulatory landscape

    International Nuclear Information System (INIS)

    Protection of wetlands became a national issue in 1988 when President George Bush pledged no net loss of wetlands in the US under his open-quotes environmental presidency.close quotes As wetlands became a national issue, the job of protecting them became an obligation for many groups, including hydro-power developers. Now, when a site selected for development includes an area that may be classified as a wetland, the developer quickly discovers the importance of recognizing and protecting these natural habitats. Federal legislation severely limits development of wetland, and most states increase the restrictions with their own wetlands regulations. The difficulty of defining wetlands complicates federal and state enforcement. Land that appears to be dry may in fact be classified as a wetland. So, even if a site appears dry, potential hydro developers must confirm whether or not any jurisdictional wetlands are present. Regulated lands include much more than marshes and swamps. Further complicating the definition of wetlands, a recent court decision found that even artificially created wetlands, such as man-made ponds, may be subject to regulation. Hydro developers must be aware of current regulatory requirements before they consider development of any site that may contain wetlands. To be certain that a site is open-quotes buildableclose quotes from the standpoint of wetlands regulation, a developer must verify (with the help of state agencies) that the property does not contain any jurisdictional wetlands. If it does, the regulatory process before development becomes much more complicated. For the short term, uncertainty abounds and extreme caution is in order. Because the regulatory process has become so complex and an agreeable definition of wetlands so elusive, the trend among the Corps and collaborating agencies is to constrict nationwide permits in favor of narrowing the jurisdictional definition of wetlands

  3. Regulatory aspects of NPP safety

    International Nuclear Information System (INIS)

    In beginning, a history of legislative process regulating industrial utilisation of nuclear energy is given, including detailed list of decrees issued by the first regulatory body supervising Czech nuclear installations - Czechoslovak Atomic Energy Commission (CSKAE). Current status of nuclear regulations and radiation protection, especially in connection with Atomic Act (Act No 18/1997 Coll.), is described. The Atomic Act transfers into the Czech legal system a number of obligations following from the Vienna Convention on Civil Liability for Nuclear Damage and Joint Protocol relating to the Application of the Vienna and Paris Convention, to which the Czech Republic had acceded. Actual duties and competence of current nuclear regulatory body - State Office for Nuclear Safety (SUJB) - are given in detail. Execution of the State supervision of peaceful utilisation of nuclear energy and ionising radiation is laid out in several articles of the Act, which comprises: control activities of the SUJB, remedial measures, penalties. Material and human resources are sufficient for fulfilment of the basic functions for which SUJB is authorised by the law. For 1998, the SUJB allotted staff of 149, approximately 2/3 of that number are nuclear safety and radiation protection inspectors. The SUJB budget for 1998 is approximately 180 million Czech crowns (roughly 6 million US dollars). Inspection activity of SUJB is carried out in three different ways: routine inspections, planned specialised inspections, inspections as a response to a certain situation (ad-hoc inspections). Approach to the licensing of major plant upgrades and backfittings are mainly illustrated on the Temelin NPP licensing. Regulatory position and practices concerning review activities are presented.

  6. Selective constraints in experimentally defined primate regulatory regions.

    Directory of Open Access Journals (Sweden)

    Daniel J Gaffney

    Full Text Available Changes in gene regulation may be important in evolution. However, the evolutionary properties of regulatory mutations are currently poorly understood. This is partly the result of an incomplete annotation of functional regulatory DNA in many species. For example, transcription factor binding sites (TFBSs, a major component of eukaryotic regulatory architecture, are typically short, degenerate, and therefore difficult to differentiate from randomly occurring, nonfunctional sequences. Furthermore, although sites such as TFBSs can be computationally predicted using evolutionary conservation as a criterion, estimates of the true level of selective constraint (defined as the fraction of strongly deleterious mutations occurring at a locus in regulatory regions will, by definition, be upwardly biased in datasets that are a priori evolutionarily conserved. Here we investigate the fitness effects of regulatory mutations using two complementary datasets of human TFBSs that are likely to be relatively free of ascertainment bias with respect to evolutionary conservation but, importantly, are supported by experimental data. The first is a collection of almost >2,100 human TFBSs drawn from the literature in the TRANSFAC database, and the second is derived from several recent high-throughput chromatin immunoprecipitation coupled with genomic microarray (ChIP-chip analyses. We also define a set of putative cis-regulatory modules (pCRMs by spatially clustering multiple TFBSs that regulate the same gene. We find that a relatively high proportion ( approximately 37% of mutations at TFBSs are strongly deleterious, similar to that at a 2-fold degenerate protein-coding site. However, constraint is significantly reduced in human and chimpanzee pCRMS and ChIP-chip sequences, relative to macaques. We estimate that the fraction of regulatory mutations that have been driven to fixation by positive selection in humans is not significantly different from zero. We also find

    1998-03-01

    This report describes a methodology to proactively and methodically assess future potential environmental legislative, regulatory, and judicial events. This is an important endeavor because new, revised, and reauthorized legislation, proposed and final regulations, and outcomes of judicial proceedings have the potential to impose new actions, directions, and costs of many organizations in the United States (related to capital investments, operating approaches, and research and development) and to affect the quality of life. The electric power industry is particularly impacted by environmental regulatory events (the term `regulatory` is used to cover all the types of legal events listed above), as the generation, transmission, and distribution of electricity affects air and water quality, require disposal of solid, hazardous, and radioactive wastes, and at times, impacts wetlands and endangered species. Numerous potential regulatory events, such as the reauthorization of the Clean Water Act and new regulations associated with global climate change, can greatly affect the power industry. Organizations poised to respond proactively to such events will improve their competitive positions, reduce their costs in the long-term, and improve their public images.

  10. Sublegislative regulatory systems and bodies

    International Nuclear Information System (INIS)

    The author discusses the character of the legal regulatory systems with a view to the relationship between risk and evaluation, puts the current regulatory instruments for control of technological risks into the context of the national constitutional law and then discusses the legal bodies authorised to make technical standards for application in the field of nuclear law. The legal requirements and obligations concerning the bodies' types of organisation and their working procedures are subsequently used to develop the criteria for an assessment of the suggested reform of the Atomic Energy Act. The author's conclusion is that the draft reform fails to comply with the standards and criteria developed by the author. In the field of law under review, which is characterized by a close concatenation of scientific-technological knowledge and legal control and thus is the crucial 'test bed' for the development of a modern law for environmental protection, there are developments to be stated leading to the right direction. But the draft does not keep what the labels sticked to it by the Government promise: The draft does not create 'a modern law for advanced safety of nuclear installations', nor does it contribute substantially to 'reaching an all party consensus about the peaceful uses of atomic energy'.

  12. Finnish regulatory experience on removal of regulatory control from materials

    International Nuclear Information System (INIS)

    The Finnish regulators and operators have a 20 years experience in the use of unconditional and conditional removal of control from the waste generated during the operation and maintenance of the NPPs. Considerable amount of resources has been saved by applying the concept. The removal of control is based on the on the Nuclear Energy Act and Decree and the regulatory guides YVL 8.2 issued by the Radiation and Nuclear Safety Authority. The Guide YVL 8.2, which application is confined only to rather moderate amount of material is planned to be updated to include also removal of control from bulk amount of very low level waste to be generated in the forthcoming decommissioning of the NPPs.

  13. Animal testing, 3R models and regulatory acceptance : Technology transition in a risk-averse context

    OpenAIRE

    Schiffelers, M.J.W.A.

    2016-01-01

    Risk avoidance has resulted in a broad range of regulations to guarantee the safety of products such as pharmaceuticals and chemicals. Many of these regulations rely on animal tests. About 3 million laboratory animals are used annually in Europe to meet such regulatory requirements.Regulatory animal testing raises concerns for scientific, ethical and economic reasons. There are many 3R initiatives to replace, reduce, or refine laboratory animal use. A broad range of 3R models is available and...

  14. The Effect of Regulatory Harmonization on Cross-border Labor Migration: Evidence from the Accounting Profession

    OpenAIRE

    Brüggemann, Ulf; Matthew J. Bloomfield; Christensen, Hans B.; Leuz, Christian

    2015-01-01

    The paper examines whether international regulatory harmonization increases cross-border labor migration. To study this question, we analyze European Union (EU) initiatives that harmonized accounting and auditing standards. Regulatory harmonization should reduce economic mobility barriers, essentially making it easier for accounting professionals to move across countries. Our research design compares the cross-border migration of accounting professionals relative to tightly-matched other prof...

    Development of the body plan is controlled by large networks of regulatory genes. A gene regulatory network that controls the specification of endoderm and mesoderm in the sea urchin embryo is summarized here. The network was derived from large-scale perturbation analyses, in combination with computational methodologies, genomic data, cis-regulatory analysis, and molecular embryology. The network contains over 40 genes at present, and each node can be directly verified at the DNA sequence level by cis-regulatory analysis. Its architecture reveals specific and general aspects of development, such as how given cells generate their ordained fates in the embryo and why the process moves inexorably forward in developmental time.

  16. Divergent allosteric patterns verify the regulatory paradigm for aspartate transcarbamylase.

    Science.gov (United States)

    Wales, M E; Madison, L L; Glaser, S S; Wild, J R

    1999-12-17

    The native Escherichia coli aspartate transcarbamoylase (ATCase, E.C. 2.1.3.2) provides a classic allosteric model for the feedback inhibition of a biosynthetic pathway by its end products. Both E. coli and Erwinia herbicola possess ATCase holoenzymes which are dodecameric (2(c3):3(r2)) with 311 amino acid residues per catalytic monomer and 153 and 154 amino acid residues per regulatory (r) monomer, respectively. While the quaternary structures of the two enzymes are identical, the primary amino acid sequences have diverged by 14 % in the catalytic polypeptide and 20 % in the regulatory polypeptide. The amino acids proposed to be directly involved in the active site and nucleotide binding site are strictly conserved between the two enzymes; nonetheless, the two enzymes differ in their catalytic and regulatory characteristics. The E. coli enzyme has sigmoidal substrate binding with activation by ATP, and inhibition by CTP, while the E. herbicola enzyme has apparent first order kinetics at low substrate concentrations in the absence of allosteric ligands, no ATP activation and only slight CTP inhibition. In an apparently important and highly conserved characteristic, CTP and UTP impose strong synergistic inhibition on both enzymes. The co-operative binding of aspartate in the E. coli enzyme is correlated with a T-to-R conformational transition which appears to be greatly reduced in the E. herbicola enzyme, although the addition of inhibitory heterotropic ligands (CTP or CTP+UTP) re-establishes co-operative saturation kinetics. Hybrid holoenzymes assembled in vivo with catalytic subunits from E. herbicola and regulatory subunits from E. coli mimick the allosteric response of the native E. coli holoenzyme and exhibit ATP activation. The reverse hybrid, regulatory subunits from E. herbicola and catalytic subunits from E. coli, exhibited no response to ATP. The conserved structure and diverged functional characteristics of the E. herbicola enzyme provides an opportunity

    The bidirectional interaction between the immune system and whole-body metabolism has been well recognized for many years. Via effects on adipocytes and hepatocytes, immune cells can modulate whole-body metabolism (in metabolic syndromes such as type 2 diabetes and obesity) and, reciprocally, host nutrition and commensal-microbiota-derived metabolites modulate immunological homeostasis. Studies demonstrating the metabolic similarities of proliferating immune cells and cancer cells have helped give birth to the new field of immunometabolism, which focuses on how the cell-intrinsic metabolic properties of lymphocytes and macrophages can themselves dictate the fate and function of the cells and eventually shape an immune response. We focus on this aspect here, particularly as it relates to regulatory T cells. PMID:27196520

  19. Regulatory aspects of clinical xenotransplantation.

    Science.gov (United States)

    Schuurman, Henk-Jan

    2015-11-01

    Xenotransplantation attracted interest from regulatory authorities, particularly after the demonstration of pig-to-human transmission of porcine endogenous retrovirus (1996). This added to the risk of a product, resulting in a Guidance of the US Food and Drug Administration (2003). This addresses the full flow chart in product manufacturing, starting with the designated pathogen-free status of the source animal; and special aspects regarding the recipient like informed consent and monitoring for infectious pathogens. Also archiving of records from the donor and recipient, as well as storage of samples is described. The European Medicines Agency issued a Guideline on xenogeneic cell therapy products (2009). Cell-based medicinal products are subject to specific regulations and directives, which apply also to xenogeneic products: the xenotransplant guidances/guidelines are an addition to these regulations. Noteworthy, acellular products like heart valves and decellularized cornea are not considered a cell therapy product, but rather a medical device with its own regulation. WHO issued relevant documents, especially about safety, and the International Xenotransplantation Association published consensus documents, a.o., addressing preclinical efficacy requirements before entering clinical trials. This manuscript presents an overview of the regulatory framework, with special focus on cell therapy products necause these are expected to reach the market first (i.e., pancreatic islets, hepatocytes and cellularized cornea); major illustrations are from the European situation. Albeit being complex, the regulation of xenotransplant products does not form a block in product development, but rather supports the introduction of efficacious and safe products to meet the medical need.

    Challenges in demonstrating interchangeability and safety, as well as the ongoing evolution of regulations governing biosimilars, have meant that the development of the biosimilars industry has not been, and will not be, a carbon copy of the generics industry. Complexity in the development process reduces the cost advantages for biosimilars that generics offer over originators. There has been a marked difference in the number of biosimilars approved by the European Medicines Agency (EMA) and US FDA due to a lack of consensus and the different rates of progress in establishing both law and stable evidence-based regulatory guidelines for biosimilars. In this review, we provide a précis of the history and status of the regulatory regimes in the USA and Europe. Included is an assessment of market and nonmarket factors that may continue to influence the development of the biosimilars industry. PMID:26620970

  1. Regulatory control of nuclear power plants

    International Nuclear Information System (INIS)

    The purpose of this book is to support IAEA training courses and workshops in the field of regulatory control of nuclear power plants as well as to support the regulatory bodies of Member States in their own training activities. The target group is the professional staff members of nuclear safety regulatory bodies supervising nuclear power plants and having duties and responsibilities in the following regulatory fields: regulatory framework; regulatory organization; regulatory guidance; licensing and licensing documents; assessment of safety; and regulatory inspection and enforcement. Important topics such as regulatory competence and quality of regulatory work as well as emergency preparedness and public communication are also covered. The book also presents the key issues of nuclear safety such as 'defence-in-depth' and safety culture and explains how these should be taken into account in regulatory work, e.g. during safety assessment and regulatory inspection. The book also reflects how nuclear safety has been developed during the years on the basis of operating experience feedback and results of safety research by giving topical examples. The examples cover development of operating procedures and accident management to cope with complicated incidents and severe accidents to stress the importance of regulatory role in nuclear safety research. The main target group is new staff members of regulatory bodies, but the book also offers good examples for more experienced inspectors to be used as comparison and discussion basis in internal workshops organized by the regulatory bodies for refreshing and continuing training. The book was originally compiled on the basis of presentations provided during the two regulatory control training courses in 1997 and 1998. The textbook was reviewed at the beginning of the years 2000 and 2002 by IAEA staff members and consistency with the latest revisions of safety standards have been ensured. The textbook was completed in the

  2. Regulatory drinking in the pigeon Columba livia.

    Kaufman, S; Peters, G

    1980-09-01

    Pigeons were subjected to stimuli known to induce regulatory drinking in mammals. Water-satiated birds drank in response to intravenous (iv) hypertonic NaCl, intraperitoneal (ip) hyperoncotic polyethylene glycol (PEG) (20 M), iv infusions of angiotensinamide, subcutaneous (sc) isoprenaline, and iv chicken kidney extract. Intravenous porcine renin failed to elicit a major drinking response. Drinking after water deprivation was reduced by an iv preload of isotonic saline. Water intake after iv hypertonic NaCl equaled the volume required for dilution to isotonicity. Water intake in response to ip PEG was larger than in rats and resulted in a parallel increase in body weight. Sensitivity to isoprenaline and angiotensinamide was less than or equal to that of rats although pigeons drank much more. Drinking responses to iv hypertonic NaCl plus ip hyperoncotic PEG were additive. Small (5 ml/kg body wt) blood losses induced delayed (after 4 h) drinking; larger blood losses were ineffective. There was no simple additive relationship between the responses to hemorrhage and hypertonic saline. In summary, the dipsogenic response of pigeons was much greater than that of mammals although sensitivity was sometimes higher and sometimes lower. PMID:7435592

  11. A new generation of vectors with increased induction ratios by overimposing a second regulatory level by attenuation

    OpenAIRE

    Royo, José Luis; Manyani, Hamid; Cebolla, Ángel; Santero, Eduardo

    2005-01-01

    A major drawback of regulated gene expression from vectors bearing strong promoters is the associated high basal expression level. Simple regulatory systems have an intrinsic limitation in the range of induction, and attempts to mutate promoters to reduce basal expression usually result in concomitant reduction of induced levels. We have explored the possibility of reducing basal levels of gene expression while keeping induced levels intact by incorporating an additional regulatory circuit co...

  19. Environment, safety, and health regulatory implementation plan

    International Nuclear Information System (INIS)

    To identify, document, and maintain the Uranium Mill Tailings Remedial Action (UMTRA) Project's environment, safety, and health (ES ampersand H) regulatory requirements, the US Department of Energy (DOE) UMTRA Project Office tasked the Technical Assistance Contractor (TAC) to develop a regulatory operating envelope for the UMTRA Project. The system selected for managing the UMTRA regulatory operating envelope data bass is based on the Integrated Project Control/Regulatory Compliance System (IPC/RCS) developed by WASTREN, Inc. (WASTREN, 1993). The IPC/RCS is a tool used for identifying regulatory and institutional requirements and indexing them to hardware, personnel, and program systems on a project. The IPC/RCS will be customized for the UMTRA Project surface remedial action and groundwater restoration programs. The purpose of this plan is to establish the process for implementing and maintaining the UMTRA Project's regulatory operating envelope, which involves identifying all applicable regulatory and institutional requirements and determining compliance status. The plan describes how the Project will identify ES ampersand H regulatory requirements, analyze applicability to the UMTRA Project, and evaluate UMTRA Project compliance status

    The International Energy Agency (IEA) considers carbon capture and storage (CCS) a crucial part of worldwide efforts to limit global warming by reducing greenhouse-gas emissions. The IEA has estimated that the broad deployment of low-carbon energy technologies could reduce projected 2050 emissions to half 2005 levels -- and that CCS could contribute about one-fifth of those reductions. Reaching that goal, however, would require around 100 CCS projects to be implemented by 2020 and over 3 000 by 2050.

  7. Adaptive Dynamics of Regulatory Networks: Size Matters

    Directory of Open Access Journals (Sweden)

    Martinetz Thomas

    2009-01-01

    Full Text Available To accomplish adaptability, all living organisms are constructed of regulatory networks on different levels which are capable to differentially respond to a variety of environmental inputs. Structure of regulatory networks determines their phenotypical plasticity, that is, the degree of detail and appropriateness of regulatory replies to environmental or developmental challenges. This regulatory network structure is encoded within the genotype. Our conceptual simulation study investigates how network structure constrains the evolution of networks and their adaptive abilities. The focus is on the structural parameter network size. We show that small regulatory networks adapt fast, but not as good as larger networks in the longer perspective. Selection leads to an optimal network size dependent on heterogeneity of the environment and time pressure of adaptation. Optimal mutation rates are higher for smaller networks. We put special emphasis on discussing our simulation results on the background of functional observations from experimental and evolutionary biology.

    Full Text Available IntroductionThank you for inviting me to share my thoughts on what the government is doing to reduce the burden on small business. I also look forward to hearing the other speakers talk about how to make the regulatory system more responsive and relevant to business needs.It is more than a year since the fall of Lehman Brothers and the beginning of the Australian Government’s response to the global financial crisis.Today, the Australian economy is showing encouraging signs of recovery. The Government’s policy responses have been largely responsible for placing Australia in a better position than most countries around the world.The Mid-Year Economic and Fiscal Outlook (MYEFO (released earlier this month showed that the economy is performing much better than was forecast in the last Budget — MYEFO shows that Australia is the only advanced economy to have recorded positive growth through the year to June 2009. MYEFO also upgraded the growth forecasts for the following two years with consequental falls in the expected peak unemployment rate.Although this is good news, the GFC has clearly affected, and is continuing to impact on, small business.A number of Australian Chamber of Commerce and Industry surveys have reported large falls in small business confidence and conditions throughout 2008 and early 2009. However, the August ACCI Small Business Survey reports that, while conditions for small business are expected to remain challenging, conditions are stabilising.This good news is supported by the most recent Commonwealth Bank – ACCI Business Expectations Survey, which shows that small, medium and large businesses are expecting business conditions to improve significantly during this quarter.It is true that small businesses succeed or fail on the creativity, ingenuity, innovation and imagination of their owners and staff. It is also true that small businesses are notoriously time poor. When considering ways to improve the regulatory

    2011-01-01

    The progressive understanding of the nature and mechanisms of T regulatory (Treg) cells in the last decade has changed the concept of immune tolerance, that is no longer considered as a mere lack of immune reactivity but as a finely regulated process that requires specific activity of cells, adhesion and secreted molecules. Tregs play a key role in maintenance of self-tolerance and induction of tolerance against ubiquitous innocuous non-self antigens, so preventing the onset of autoimmune diseases and allergies. This review will focus on the Treg response in allergy that is characterized by a down-regulation of allergen specific T cell proliferation and inhibition of both Th1 and Th2 cytokines production. Hence, Treg cells suppress allergen-specific Th1 and Th2 cell responses playing an important role in the physiological immune response to allergens. Further, Treg cells are able to suppress IgE production by B lymphocytes and directly or indirectly inhibit the activity of allergic inflammation effector cells, namely eosinophils, basophils and mastcells. Finally, increasing evidence suggests that Treg cells are also implicated in chronicity development of inflammatory diseases. This appears to happen through a fine interaction they entertain with resident tissue cells and has been particularly highlighted in the study of airways remodeling in asthma. The understanding of the mechanisms underlying allergen tolerance has brought new interest in the development of new allergy treatment, able to target Treg cells, both in allergy prevention and in the therapy of established allergy.

  16. Nuclear energy - some regulatory aspects

    International Nuclear Information System (INIS)

    The nuclear industry is often perceived by the public as being uniquely hazardous. As a consequence, the demands placed upon a nuclear regulatory agency invariably include sorting out the valid from the invalid. As the public becomes better informed, more time should become available for regulating the industry. The Canadian nuclear safety philosophy relies upon fundamental principle and basic criteria which licensees must show they are meeting at all stages in the development of a nuclear facility. In reactors, the concept of defence in depth involves the use of well-qualified personnel, compliance with national and international engineering codes and standards, the separation of process and safety systems, frequent testing of safety systems, redundancy in monitoring, control and initiation systems, multiple barriers against fission product release, and strict enforcement of compliance measurements. The Atomic Energy Control Board is writing a set of licensing guides to cover the whole nuclear fuel cycle; however, these will not lead to the impsition of a 'design by regulation' approach in Canada.

  17. A regulatory perspective on design and performance requirements for engineered systems in high-level waste

    International Nuclear Information System (INIS)

    For engineered systems, this paper gives an overview of some of the current activities at the U.S. Nuclear Regulatory Commission (NRC), with the intent of elucidating how the regulatory process works in the management of high-level waste (HLW). Throughout the waste management cycle, starting with packaging and transportation, and continuing to final closure of a repository, these activities are directed at taking advantage of the prelicensing consultation period, a period in which the NRC, DOE and others can interact in ways that will reduce regulatory, technical and institutional uncertainties, and open the path to development and construction of a deep geologic repository for permanent disposal of HLW. Needed interactions in the HLW program are highlighted. Examples of HLW regulatory activities are given in discussions of a multipurpose-cask concept and of current NRC work on the meaning of the term substantially complete containment

    A prospective field study conducted with runners training for an upcoming marathon (Marathon of Rome 2013) examined the relation between regulatory modes, locomotion and assessment, and stress. Integrating regulatory mode theory and the dualistic model of passion, we hypothesized that the relation between regulatory modes (evaluated 3 months before the race) and the experience of stress approaching the marathon, is mediated by the type of passion (harmonious vs obsessive) athletes experience with regard to marathoning. Results revealed that (a) locomotion positively predicted harmonious passion, which in turn reduced athletes' experience of stress; and (b) assessment positively predicted obsessive passion, which in turn enhanced athletes' experience of stress. Overall, the present results suggest that proximal psychological mechanisms such as basic regulatory mode orientations can predict distal outcomes such as stress indirectly through their relation with motivational phenomena such as passion.

  20. Regulatory focus and the assignment of punishment

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available Regulatory Focus has been demonstrated to influence human behavior in a number of domains, such as object valuation and readiness to commit time or money to social projects. It has also been demonstrated to influence an individual’s approach to mistakes; and a person’s preference for global or local processing of information. The present work seeks to consider how regulatory focus might interact with punitive behaviors, specifically, the assignment of legal punishment. In this study, 240 undergraduates completed a series of written instruments that assessed their regulatory focus. They read a vignette that described a target that commits a crime, is detected by the police, and is arrested due to a careless mistake. Participants were asked what level of legal punishment they deemed appropriate. Participants’ punitive evaluations show that there are significant interactions a between the regulatory focus of the participant and the regulatory focus of the target and b between the regulatory focus of the participant and the level of detail used to describe the target and her behavior. In each case, when the regulatory foci matched, causing ‘fit,’ the participant was more lenient than in the non-fit condition.

  2. Preliminary regulatory assessment of nuclear power plants vulnerabilities

    International Nuclear Information System (INIS)

    Preliminary attempts to develop models for nuclear regulatory vulnerability assessment of nuclear power plants are presented. Development of the philosophy and computer tools could be new and important insight for management of nuclear operators and nuclear regulatory bodies who face difficult questions about how to assess the vulnerability of nuclear power plants and other nuclear facilities to external and internal threats. In the situation where different and hidden threat sources are dispersed throughout the world, the assessment of security and safe operation of nuclear power plants is very important. Capability to evaluate plant vulnerability to different kinds of threats, like human and natural occurrences and terrorist attacks and preparation of emergency response plans and estimation of costs are of vital importance for assurance of national security. On the basis of such vital insights, nuclear operators and nuclear regulatory bodies could plan and optimise changes in oversight procedures, organisations, equipment, hardware and software to reduce risks taking into account security and safety of nuclear power plants operation, budget, manpower, and other limitations. Initial qualitative estimations of adapted assessments for nuclear applications are shortly presented. (author)

    International Nuclear Information System (INIS)

    The Energy Reorganization Act of 1974 which established the Nuclear Regulatory Commission required GAO to evaluate the Commission's performance by January 18, 1980. This report responds to that requirement. GAO concluded that, although improvements have been made, the Commission's nuclear regulatory performance can be characterized best as slow, indecisive, cautious - in a word, complacent. This has largely resulted from a lack of aggressive leadership as evidenced by the Commissioners' failure to establish regulatory goals, control policymaking, and most importantly, clearly define their roles in nuclear regulation

    regulatory competition are a reality in today’s global financial market, and the financial sector is different from their traditional fields of application: the ease of arbitrage, the fragility of banking and the risks involved are exceptional. Most importantly, regulatory arbitrage does not or only rarely......The decades-long discussion on the merits of regulatory competition appears in a new light on the global financial market. There are a number of strategies that market participants use to avoid the reach of regulation, in particular by virtue of shifting trading abroad or else relocating activities...

    The Gal4-UAS regulatory system of yeast is widely used to modulate gene expression in Drosophila; however, there are limitations to its usefulness in transgenic zebrafish, owing to progressive methylation and silencing of the CpG-rich multicopy upstream activation sequence. Although a modified, less repetitive UAS construct may overcome this problem, it is highly desirable to have additional transcriptional regulatory systems that can be applied independently or in combination with the Gal4/UAS system for intersectional gene expression. The Q transcriptional regulatory system of Neurospora crassa functions similarly to Gal4/UAS. QF is a transcriptional activator that binds to the QUAS upstream regulatory sequence to drive reporter gene expression. Unlike Gal4, the QF binding site does not contain essential CpG dinucleotide sequences that are subject to DNA methylation. The QS protein is a repressor of QF mediated transcriptional activation akin to Gal80. The functionality of the Q system has been demonstrated in Drosophila and C. elegans and we now report its successful application to a vertebrate model, the zebrafish, Danio rerio. Several tissue-specific promoters were used to drive QF expression in stable transgenic lines, as assessed by activation of a QUAS:GFP transgene. The QS repressor was found to dramatically reduce QF activity in injected zebrafish embryos; however, a similar repression has not yet been achieved in transgenic animals expressing QS under the control of ubiquitous promoters. A dual reporter construct containing both QUAS and UAS, each upstream of different fluorescent proteins was also generated and tested in transient assays, demonstrating that the two systems can work in parallel within the same cell. The adoption of the Q system should greatly increase the versatility and power of transgenic approaches for regulating gene expression in zebrafish. PMID:23792917

  13. Empirical studies of regulatory restructuring and incentives

    Science.gov (United States)

    Knittel, Christopher Roland

    This dissertation examines the actions of firms when faced with regulatory restructuring. Chapter I examines the equilibrium pricing behavior of local exchange telephone companies under a variety of market structures. In particular, the pricing behavior of three services are analyzed: residential local service, business local service, and intraLATA toll service. Beginning in 1984, a variety of market structure changes have taken place in the local telecommunications industry. I analyze differences in the method of price-setting regulation and the restrictions on entry. Specifically, the relative pricing behavior under rate of return and price cap regulation is analyzed, as well as the impact of entry in the local exchange and intraLATA toll service markets. In doing so, I estimate an empirical model that accounts for the stickiness of rates in regulated industries that is based on firm and regulator decision processes in the presence of adjustment costs. I find that, faced with competitive pressures that reduce rates in one service, incumbent firm rates increase in other services, thereby reducing the benefits from competition. In addition, the findings suggest that price cap regulation leads to higher rates relative to rate-of-return regulation. Chapter 2 analyzes the pricing and investment behavior of electricity firms. Electricity and natural gas markets have traditionally been serviced by one of two market structures. In some markets, electricity and natural gas are sold by a dual-product regulated monopolist, while in other markets, electricity and natural gas are sold by separate single-product regulated monopolies. This paper analyzes the relative pricing and investment decisions of electricity firms operating in the two market structures. The unique relationship between these two products imply that the relative incentives of single and dual-product firms are likely to differ. Namely electricity and natural gas are substitutes in consumption while natural

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    This paper compares the development of telecom regulation andderegulation between some typical Asian countries, and analyzes the telecom regulatory systems and industrial organizations of China. This paper also investigates the approaches and strategies of Asian countries to reduce the regulation, reinforce the competition and establish efficient telecom industries. Having examined the Asian telecommunication markets, the paper attempts to apply the lessons learned from the opening of the telecoms markets of the developed economies. Finally the paper contends that if Asian economies wish to have nationally based companies, state or private enterprises, in a competitive postion, the format of the implementation of the WTO/GATS basic telecoms agreement should be carefully examined.

  16. Regulatory control of radiation sources in Slovakia

    International Nuclear Information System (INIS)

    In Slovakia, there are two regulatory authorities. Regulatory control of the utilization of nuclear energy, based on the Slovak National Council's law No. 130/1998 on the peaceful uses of nuclear energy, is exercised by the Nuclear Regulatory Authority of the Slovak Republic. The second regulatory authority - the Ministry of Health - is empowered by law No. 72/1994 on the protection of human health to license radiation sources and is responsible for radiation protection supervision (there are nearly 3000 establishments with sealed sources, radiation generators and unsealed sources in Slovakia). Pursuant to a new radiation protection regulation based on international standards, radiation sources are to be categorized in six classes according to the associated exposure and contamination hazards. A national strategy for improving the safety of radiation sources over their life-cycle and for the management of disused and orphan sources is being prepared for governmental approval. (author)

  3. Safety culture as a matter of regulatory control and regulatory effectiveness

    International Nuclear Information System (INIS)

    More than 15 years have passed since the term 'safety culture' was introduced by the International Nuclear Safety Advisory Group (INSAG), and although the concept now is widely accepted, practical applications and characteristics have been disseminated mainly for nuclear power plant operating organizations. There is still a lack of international guidance on the use of safety culture as a regulatory matter and on the application of the concept within regulatory organizations. This work explores the meaning of safety culture in two different fields: as an element of safety management systems it shall be a matter of regulatory control; as a complementary tool for quality management it should be used to enhance regulatory effectiveness. Brazilian recent experience on regulating nuclear power reactors provide some examples on how the concept of safety culture may influence regulatory strategies and regulatory management. (author)

  1. Regulatory Authorities for Radiation Protection: A Comparison

    International Nuclear Information System (INIS)

    Full text: Concerning the law, some countries have basic legislation compatible with the BSS (Basic Safety Standard). Some countries are in the process of adopting such laws. In some countries, more than one law concerning radiation protection has been introduced, while in a few countries, the existing laws will be modified or amended soon in order to improve the position of the Regulatory Authority. In some countries the regulatory control is independent but in some cases the Ministry of Health is still in this control. There are also cases where the Regulatory Authority is located in Ministry of Health but legal mechanisms exist to ensure effective independence of the Regulatory Authority. The number of staff of the Regulatory Authority also differs from one country to another. In some cases Regulatory Authorities are actively involved in supporting services, for instance individual monitoring, which can be carried out by outside authorised laboratories. Notification, authorisation, inspection and enforcement is effective in some countries while in other countries those are in developing process. Concerning occupational exposure control, some countries have fully implemented individual monitoring and the other are partially operational. Workplace monitoring still needs some improvement.

    International Nuclear Information System (INIS)

    The integrated demonstration program at the Savannah River Site (SRS) involves demonstration, testing and evaluation of new characterization, monitoring, drilling and remediation technologies for soils and groundwater impacted by organic solvent contamination. The regulatory success of the demonstration program has developed as a result of open communications between the regulators and the technical teams involved. This open dialogue is an attempt to allow timely completion of applied environmental restoration demonstrations while meeting all applicable regulatory requirements. Simultaneous processing of multiple regulatory documents (satisfying RCRA, CERCLA, NEPA and various state regulations) has streamlined the overall permitting process. Public involvement is achieved as various regulatory documents are advertised for public comment consistent with the site's community relations plan. The SRS integrated demonstration has been permitted and endorsed by regulatory agencies, including the Environmental Protection Agency (EPA) and the South Carolina Department of Health and Environmental Control. EPA headquarters and regional offices are involved in DOE's integrated Demonstration Program. This relationship allows for rapid regulatory acceptance while reducing federal funding and time requirements. (author)

    Recent studies highlight the implication of innate and adaptive immunity in the pathophysiology of Alzheimer's disease, and foster immunotherapy as a promising strategy for its treatment. Vaccines targeting amyloid-β peptide provided encouraging results in mouse models, but severe side effects attributed to T cell responses in the first clinical trial AN1792 underlined the need for better understanding adaptive immunity in Alzheimer's disease. We previously showed that regulatory T cells critically control amyloid-β-specific CD4(+)T cell responses in both physiological and pathological settings. Here, we analysed the impact of regulatory T cells on spontaneous disease progression in a murine model of Alzheimer's disease. Early transient depletion of regulatory T cells accelerated the onset of cognitive deficits in APPPS1 mice, without altering amyloid-β deposition. Earlier cognitive impairment correlated with reduced recruitment of microglia towards amyloid deposits and altered disease-related gene expression profile. Conversely, amplification of regulatory T cells through peripheral low-dose IL-2 treatment increased numbers of plaque-associated microglia, and restored cognitive functions in APPPS1 mice. These data suggest that regulatory T cells play a beneficial role in the pathophysiology of Alzheimer's disease, by slowing disease progression and modulating microglial response to amyloid-β deposition. Our study highlights the therapeutic potential of repurposed IL-2 for innovative immunotherapy based on modulation of regulatory T cells in Alzheimer's disease. PMID:26912648

    2011-01-01

    Inferring gene regulatory networks from large-scale expression data is an important topic in both cellular systems and computational biology. The inference of regulators might be the core factor for understanding actual regulatory conditions in gene regulatory networks, especially when strong regulators do work significantly, in this paper, we propose a novel approach based on combining neuro-fuzzy network models with biological knowledge to infer strong regulators and interrelated fuzzy rules. The hybrid neuro-fuzzy architecture can not only infer the fuzzy rules, which are suitable for describing the regulatory conditions in regulatory networks, but also explain the meaning of nodes and weight value in the neural network. It can get useful rules automatically without factitious judgments. At the same time, it does not add recursive layers to the model, and the model can also strengthen the relationships among genes and reduce calculation. We use the proposed approach to reconstruct a partial gene regulatory network of yeast. The results show that this approach can work effectively.

  13. Evaluation of regulatory guides potentially useful to geologic repository development

    International Nuclear Information System (INIS)

    The US Regulatory Commission Regulatory Guide series provides a set of regulatory and technical guidelines for achieving and demonstrating regulatory compliance for various segments of the nuclear fuel cycle. Of these regulatory guides only few specifically pertain to high-level waste repository activities. The overwhelming majority pertain to other, more mature aspects of the nuclear cycle. It is believed that conscientious, reasoned application of the fundamental regulatory bases underlying the positions in these other regulatory guides could provide a solid regulatory starting point for repository development activities. This information report provides a summary screening of regulatory guides published as of September 1983 and provides an initial assessment of the potential usefulness of these regulatory guides to repository design and operation activities

  18. Regulatory aspects of criticality control in Australia

    International Nuclear Information System (INIS)

    With the creation of Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) the Australian approach to criticality safety was revisited. Consistency with international best practices is required by the Act that created ARPANSA and this was applied to practices in criticality safety adopted in other countries. This required extensive regulatory efforts both in auditing the major Australian Nuclear Operator, Australian Nuclear Science and Technology Organisation (ANSTO), and assessing the existing in Australia criticality safety practices and implementing the required changes using the new legislative power of ARPANSA. The adopted regulatory approach is formulated through both the issued by ARPANSA licenses for nuclear installations (including reactors, fuel stores and radioactive waste stores) and the string of new regulatory documents, including the Regulatory Assessment Principles and the Regulatory Assessment Guidelines for criticality safety. The main features of the adopted regulation include the requirements of independent peer-review, ongoing refresher training coupled with annual accreditation and the reliance on the safe design rather than on an administrative control.

  19. Functional characterization of variations on regulatory motifs.

    Directory of Open Access Journals (Sweden)

    Michal Lapidot

    2008-03-01

    Full Text Available Transcription factors (TFs regulate gene expression through specific interactions with short promoter elements. The same regulatory protein may recognize a variety of related sequences. Moreover, once they are detected it is hard to predict whether highly similar sequence motifs will be recognized by the same TF and regulate similar gene expression patterns, or serve as binding sites for distinct regulatory factors. We developed computational measures to assess the functional implications of variations on regulatory motifs and to compare the functions of related sites. We have developed computational means for estimating the functional outcome of substituting a single position within a binding site and applied them to a collection of putative regulatory motifs. We predict the effects of nucleotide variations within motifs on gene expression patterns. In cases where such predictions could be compared to suitable published experimental evidence, we found very good agreement. We further accumulated statistics from multiple substitutions across various binding sites in an attempt to deduce general properties that characterize nucleotide substitutions that are more likely to alter expression. We found that substitutions involving Adenine are more likely to retain the expression pattern and that substitutions involving Guanine are more likely to alter expression compared to the rest of the substitutions. Our results should facilitate the prediction of the expression outcomes of binding site variations. One typical important implication is expected to be the ability to predict the phenotypic effect of variation in regulatory motifs in promoters.

  20. Use of risk information in regulatory reviews

    International Nuclear Information System (INIS)

    The regulatory framework for licensing any high-level waste repository at Yucca Mountain in the United States, calls for appropriate use of risk information to ensure operational safety during the pre-closure period and long-term safety during the post-closure period. This paper focuses on the post-closure period. Regulations in the Code of Federal Regulations (CFR), Title 10, Part 63, apply to any repository at Yucca Mountain and envision use of probabilistic methods to develop quantitative risk information. Accumulated engineering and scientific experience at Yucca Mountain and analog sites and quantitative risk information from studies conducted by the implementer, regulator, and others are combined to formulate 'risk insights,' which are then used to plan and execute regulatory reviews. The U.S. Nuclear Regulatory Commission (NRC) and the Center for Nuclear Waste Regulatory Analyses (CNWRA) recently consolidated the knowledge gained during several g ears and developed such risk insights for the potential repository at Yucca Mountain. This paper discusses the types of risk information used to generate risk insights and how the risk insights will be used in regulatory reviews. A companion paper presents more details on sensitivity analysis methods used to generate risk information. (authors)

  1. Phylogeny based discovery of regulatory elements

    2006-05-01

    Full Text Available Abstract Background Algorithms that locate evolutionarily conserved sequences have become powerful tools for finding functional DNA elements, including transcription factor binding sites; however, most methods do not take advantage of an explicit model for the constrained evolution of functional DNA sequences. Results We developed a probabilistic framework that combines an HKY85 model, which assigns probabilities to different base substitutions between species, and weight matrix models of transcription factor binding sites, which describe the probabilities of observing particular nucleotides at specific positions in the binding site. The method incorporates the phylogenies of the species under consideration and takes into account the position specific variation of transcription factor binding sites. Using our framework we assessed the suitability of alignments of genomic sequences from commonly used species as substrates for comparative genomic approaches to regulatory motif finding. We then applied this technique to Saccharomyces cerevisiae and related species by examining all possible six base pair DNA sequences (hexamers and identifying sequences that are conserved in a significant number of promoters. By combining similar conserved hexamers we reconstructed known cis-regulatory motifs and made predictions of previously unidentified motifs. We tested one prediction experimentally, finding it to be a regulatory element involved in the transcriptional response to glucose. Conclusion The experimental validation of a regulatory element prediction missed by other large-scale motif finding studies demonstrates that our approach is a useful addition to the current suite of tools for finding regulatory motifs.

  6. Pipeline Drag Reducers

    International Nuclear Information System (INIS)

    Pipeline drag reducers have proven to be an extremely powerful tool in fluid transportation. High molecular weight polymers are used to reduce the frictional pressure loss ratio in crude oil pipelines, refined fuel and aqueous pipelines. Chemical structure of the main used pipeline drag reducers is one of the following polymers and copolymers classified according to the type of fluid to ; low density polyethylene, copolymer of I-hexane cross linked with divinyl benzene, polyacrylamide, polyalkylene oxide polymers and their copolymers, fluorocarbons, polyalkyl methacrylates and terpolymer of styrene, alkyl acrylate and acrylic acid. Drag reduction is the increase in pump ability of a fluid caused by the addition of small amounts of an additive to the fluid. The effectiveness of a drag reducer is normally expressed in terms of percent drag reduction. Frictional pressure loss in a pipeline system is a waste of energy and it costly. The drag reducing additive minimizes the flow turbulence, increases throughput and reduces the energy costs. The Flow can be increased by more than 80 % with existing assets. The effectiveness of the injected drag reducer in Mostorod to Tanta crude oil pipeline achieved 35.4 % drag reduction and 23.2 % flow increase of the actual performance The experimental application of DRA on Arab Petroleum Pipeline Company (Summed) achieved a flow increase ranging from 9-32 %

  7. Targeting regulatory T cells in cancer.

    LENUS (Irish Health Repository)

    Byrne, William L

    2012-01-31

    Infiltration of tumors by regulatory T cells confers growth and metastatic advantages by inhibiting antitumor immunity and by production of receptor activator of NF-kappaB (RANK) ligand, which may directly stimulate metastatic propagation of RANK-expressing cancer cells. Modulation of regulatory T cells can enhance the efficacy of cancer immunotherapy. Strategies include depletion, interference with function, inhibition of tumoral migration, and exploitation of T-cell plasticity. Problems with these strategies include a lack of specificity, resulting in depletion of antitumor effector T cells or global interruption of regulatory T cells, which may predispose to autoimmune diseases. Emerging technologies, such as RNA interference and tetramer-based targeting, may have the potential to improve selectivity and efficacy.

  11. Transcription regulatory networks analysis using CAGE

    KAUST Repository

    Tegnér, Jesper N.

    2009-10-01

    Mapping out cellular networks in general and transcriptional networks in particular has proved to be a bottle-neck hampering our understanding of biological processes. Integrative approaches fusing computational and experimental technologies for decoding transcriptional networks at a high level of resolution is therefore of uttermost importance. Yet, this is challenging since the control of gene expression in eukaryotes is a complex multi-level process influenced by several epigenetic factors and the fine interplay between regulatory proteins and the promoter structure governing the combinatorial regulation of gene expression. In this chapter we review how the CAGE data can be integrated with other measurements such as expression, physical interactions and computational prediction of regulatory motifs, which together can provide a genome-wide picture of eukaryotic transcriptional regulatory networks at a new level of resolution. © 2010 by Pan Stanford Publishing Pte.

    Regulatory guidelines are intended to provide recommendations on ways to achieve greater harmonization in the interpretation and application of technical procedures and requirements for product registration in order to reduce or obviate replication of the testing carried out during the research and development of new products. The objectives of such harmonization are more economical use of human, animal and material resources; the elimination of unnecessary delay in the global development and availability of new products while maintaining safeguards on quality, safety and efficacy; and the fulfillment of regulatory obligations to protect public health.

    Over the years various reduced fluid models have been obtained for modeling plasmas, with the goal of capturing important physics while maintaining computability. Such models have included the physics contained in various generalizations of Ohm's law, including Hall drift and electron inertia. In a recent publication it was shown that full 3D extended MHD is a Hamiltonian system by finding its noncanonical Poisson bracket. Subsequently, this bracket was shown to be derivable from that for Hall MHD by a series of remarkable transformations, which greatly simplifies the proof of the Jacobi identity and allows one to immediately obtain generalizations of the helicity and cross helicity. In this poster we use this structure to obtain exact reduced fluid models with the effects of full two-fluid theory. Results of numerical computations of collisionless reconnection using an exact reduced 4-field model will be presented and analytical comparisons of mode structure of previous reduced models will be made.

    Measurements of ellipticities of background galaxies are sensitive to the reduced shear, the cosmic shear divided by (1-{kappa}) where {kappa} is the projected density field. They compute the difference between shear and reduced shear both analytically and with simulations. The difference becomes more important an smaller scales, and will impact cosmological parameter estimation from upcoming experiments. A simple recipe is presented to carry out the required correction.

  2. Independence and regulatory effectiveness: The Chilean experience

    International Nuclear Information System (INIS)

    International binding documents state that Member States should provide an effectively independent Regulatory Body. There are no recommendations on how independent a Regulatory Body must be. As a result, many different regulatory structures are found worldwide. Economical development status of Member States can be easily correlated to their regulatory organizations; nuclear power programs are also decisory. Along the last fifty years, regulatory activities in Chile have gone through several changes: before 1974 radioactive facilities were controlled by the Ministry of Health. A Supreme Decree issued on June 1974, approved the 'Regulations on Licensing (of radioactive facilities)', conferring this faculty to the Chilean Nuclear Energy Commission. The CNEC had, de facto, the same faculties regarding nuclear facilities. The Nuclear Safety Law, published in 1984 stated that the Chilean Nuclear Energy Commission (CNEC) was the competent authority regarding nuclear facilities, while Regional Health Services belonging to the Ministry of Health, were competent over all radioactive facilities. In 1987 the Law No. 18.730 amended the Nuclear Safety Law, transferring the competence over 1st category radioactive facilities and associated matters to the CNEC. In 2004 the Ministry of Health went under a great reorganization: the Law No. 19.937 defined new competent authorities, providing an effective independence of the regulatory functions. In 2001, the Board of Directors of the CNEC delegated the faculty of granting authorizations to the Head of the Nuclear and Radiological Safety Department. In 2005, the Board also delegated the faculties of proposing regulations and standards and prosecuting regulation violators on the person of the Head of the Nuclear and Radiological Safety Department. Both, the Ministry of Health and the CNEC, have given decisory steps towards fulfilling the principle of regulatory independence: the first one by separating functions at the level of

  3. Communication planning by the nuclear regulatory body

    International Nuclear Information System (INIS)

    The national regulatory body, whose primary mission is to exercise regulatory control over nuclear facilities and the use of radiation sources, but not to promote their use, may be the most credible source of neutral, balanced and accurate information about issues relating to nuclear and radiation safety. It is therefore important for a regulatory body to establish and exercise an effective communication programme to acquaint the public with its oversight functions, capabilities and effectiveness. If the regulatory body is to maintain credibility and to deal promptly and effectively with nuclear or radiological accidents and any other events that may give rise to significant public concerns, and is to communicate clearly and effectively with the public, it must have adequate resources, including experts in nuclear safety. And if maintaining public confidence in the authorities and avoiding unnecessary concerns are among its principal objectives, it must be able to communicate understandably and truthfully about the known extent of any accident, the actions taken in response to it and its implications. In the past, psychological effects as a result of certain severe nuclear and radiological accidents have been compounded by a lack of candour with the public on the part of the authorities and an absence of an appropriate programme of public information. This publication describes good practices and gives practical examples of how the regulatory body can establish a systematic and structured programme for enhancing effective communication with various parties and under various circumstances. The report presupposes an adequate national infrastructure, including an independent regulatory body with sufficient authority and resources to discharge its responsibilities for the regulation of safety. This Safety Report covers the elements of a regulatory body's programme for communication with various audiences and under the different circumstances that may be encountered

  6. Needs of research for regulatory purposes

    International Nuclear Information System (INIS)

    Hans Wanner, Swiss Federal Nuclear Safety Inspectorate (ENSI), presented a general overview of regulatory research at the international level based on a preliminary input from international colleagues and observed that the question of active involvement of nuclear regulatory and supervisory bodies in R and D projects has become a topic of increasing interest in recent years even if the way in which research is included in regulatory activities varies from country to country. The range spans from countries with no regulatory R and D activities to countries with extensive activities that are often carried out by independent research organisations acting on behalf of the regulatory body. In a few countries, the regulator and implementer have their research carried out by the same research institutes. As an example H. Wanner explained the organisation of R and D work in Switzerland. He presented the potential merits of R and D work carried out by the regulator and introduced a number of questions that would gain from being addressed at an international level. He stressed that the R and D work performed by the implementer must be comprehensive and there should be, in principle, no need for complementary work by the regulatory body. Nevertheless, R and D work of the regulator has still several merits. It improves the regulator's necessary competence to review the safety case allowing it to rely on the scientific community. It provides the regulator's independence, allowing a different view on the safety case from the implementer's view. By bringing to the fore the scientific and technical ability of the regulator, R and D work by the regulator provides additional confidence to the stakeholders in the credibility of the regulator. There may exist further motivations for the regulator to carry out its own R and D projects, among which is the verification of key safety issues or the investigation of topics not addressed by the implementer, i.e., to fill scientific gaps. The

  7. Regulatory issues in merchant transmission investment

    International Nuclear Information System (INIS)

    Merchant investment in electricity transmission networks (MTI) is now legally allowed. Predominantly driven by the fear of underinvestment, regulators examine this possibility and given that MTI is a possibility, the regulators face a new set of questions. This paper raises and examines regulatory questions especially from a European institutional framework. The regulatory issues concern the competition effect, the ownership, access regime and the must-offer provision. The paper argues to leave light-handed unregulated MTI light handed and refrain from additional measures. In most cases, it is justified to refrain from sector-specific arrangements because competition,law, if necessary at all, will suffice. However, details matter. (author)

  8. Legal and Regulatory Frameworks for Decommissioning and Waste Management

    International Nuclear Information System (INIS)

    Safe and efficient decommissioning and waste management requires clear structures for allocating responsibility and funding. Organisation of decommissioning and waste management activities and the regulatory environment within which those activities are undertaken should also allow the supply chain to prosper and, wherever possible, reduce barriers to international availability of resources and waste facilities. Radioactive waste treatment and disposal in particular raises both legal and political challenges to effective international co-operation, yet options for decommissioning and waste management are maximised where international barriers can be minimised. Added to this, international nuclear liabilities issues must be managed so as to avoid unnecessary deterrents to international mobility of capability within the decommissioning market. Contractual terms and insurance arrangements for international shipments of nuclear waste and materials will also need to take into account imminent changes to liabilities conventions, ensuring compliance and management of compliance costs (of both insurance and management time). This paper explores legal and commercial structures intended to support effective decommissioning and waste management and examines regulatory and commercial factors affecting the ability of facility operators to utilise internationally available capability. It focusses on: - strategic approaches developed in the UK to address decommissioning and waste management liabilities associated with the UK's first and second generation civil nuclear sites and comparison of those approaches with other jurisdictions with significant decommissioning liabilities; - liability and compliance risks associated with navigating international nuclear liabilities regimes in context of both mobility of decommissioning capability and international waste shipment; and - regulatory issues affecting international availability of waste treatment facilities, including

  9. Leadership in Safety and Regulatory Oversight: Defining the Leadership Framework in Pakistan Nuclear Regulatory Authority

    International Nuclear Information System (INIS)

    'IAEA Safety Standards: Fundamental Safety Principles (1)' establishes the fundamental safety objectives, safety principles and concepts that provide the bases for the IAEA's safety standards and its safety related programme. The third principle relates to 'Leadership and management for safety'. It requires that effective leadership and management for safety must be established and sustained in organizations concerned with, and facilities and activities that give rise to radiation risks. . However, regulators are finding it difficult to define a framework for leadership in safety and regulatory oversight on the basis of which competency in leadership can be developed. There have been a number of literature on competency building for nuclear regulatory staff, although they do emphasis on systematic assessment of training as a preclude for development of comprehensive training program but the competency required for leadership development in safety and regulatory oversight is not covered. This paper attempts to define a competency framework for leadership in nuclear safety and regulatory oversight in Pakistan Nuclear Regulatory Authority (PNRA). It is expected that this framework can be used (adapted/adopted) by other regulatory bodies for developing leadership in their staff. We believe that new countries embarking on nuclear power programme will especially find this interesting and useful as they will also face similar challenges as faced by Pakistan Nuclear Regulatory Authority during its formative year.

  10. Categorization and selection of regulatory approaches for nuclear power plants

    International Nuclear Information System (INIS)

    Several new regulatory approaches have been introduced to Japanese nuclear safety regulations, in which a prescriptive and deterministic approach had traditionally predominated. However, the options of regulatory approaches that can possibly be applied to nuclear safety regulations as well as the methodology for selecting the options are not systematically defined. In this study, various regulatory approaches for nuclear power plants are categorized as prescriptive or nonprescriptive, outcome-based or process-based, and deterministic or risk-informed. 18 options of regulatory approaches are conceptually developed and the conditions for selecting the appropriate regulatory approaches are identified. Current issues on nuclear regulations regarding responsibilities, transparency, consensus standards and regulatory inspections are examined from the viewpoints of regulatory approaches to verify usefulness of the categorization and selection concept of regulatory approaches. Finally, some of the challenges at the transitional phase of regulatory approaches are discussed. (author)

  11. Inference of Gene Regulatory Network Based on Local Bayesian Networks

    Science.gov (United States)

    Liu, Fei; Zhang, Shao-Wu; Guo, Wei-Feng; Chen, Luonan

    2016-01-01

    The inference of gene regulatory networks (GRNs) from expression data can mine the direct regulations among genes and gain deep insights into biological processes at a network level. During past decades, numerous computational approaches have been introduced for inferring the GRNs. However, many of them still suffer from various problems, e.g., Bayesian network (BN) methods cannot handle large-scale networks due to their high computational complexity, while information theory-based methods cannot identify the directions of regulatory interactions and also suffer from false positive/negative problems. To overcome the limitations, in this work we present a novel algorithm, namely local Bayesian network (LBN), to infer GRNs from gene expression data by using the network decomposition strategy and false-positive edge elimination scheme. Specifically, LBN algorithm first uses conditional mutual information (CMI) to construct an initial network or GRN, which is decomposed into a number of local networks or GRNs. Then, BN method is employed to generate a series of local BNs by selecting the k-nearest neighbors of each gene as its candidate regulatory genes, which significantly reduces the exponential search space from all possible GRN structures.

    The inference of gene regulatory networks (GRNs) from expression data can mine the direct regulations among genes and gain deep insights into biological processes at a network level. During past decades, numerous computational approaches have been introduced for inferring the GRNs. However, many of them still suffer from various problems, e.g., Bayesian network (BN) methods cannot handle large-scale networks due to their high computational complexity, while information theory-based methods cannot identify the directions of regulatory interactions and also suffer from false positive/negative problems. To overcome the limitations, in this work we present a novel algorithm, namely local Bayesian network (LBN), to infer GRNs from gene expression data by using the network decomposition strategy and false-positive edge elimination scheme. Specifically, LBN algorithm first uses conditional mutual information (CMI) to construct an initial network or GRN, which is decomposed into a number of local networks or GRNs. Then, BN method is employed to generate a series of local BNs by selecting the k-nearest neighbors of each gene as its candidate regulatory genes, which significantly reduces the exponential search space from all possible GRN structures. Integrating these local BNs forms a tentative network or GRN by performing CMI, which reduces redundant regulations in the GRN and thus alleviates the false positive problem. The final network or GRN can be obtained by iteratively performing CMI and local BN on the tentative network. In the iterative process, the false or redundant regulations are gradually removed. When tested on the benchmark GRN datasets from DREAM challenge as well as the SOS DNA repair network in E.coli, our results suggest that LBN outperforms other state-of-the-art methods (ARACNE, GENIE3 and NARROMI) significantly, with more accurate and robust performance.

    Improved diagnostic tests for tuberculosis case detection are urgently needed that are affordable, robust, and easy to use so that they can be implemented widely. The mandate of national regulatory authorities is to ensure the safety and effectiveness of diagnostics, protecting the population against unsafe products while expediting access to beneficial new devices. However, regulatory approval processes in the developing world are often complex, lengthy, and not transparent. Recent progress in building regulatory capacity using harmonized approaches will reduce duplication in clinical performance studies and manufacturing audits, facilitate information sharing through trust and mutual confidence building, and ultimately improve efficiency. These savings can be passed onto the consumers in the form of more affordable pricing and allowing new high-quality tests for tuberculosis to be introduced more quickly and without delay.

  16. Generic Use of Uncertainties in Endpoint Predictions for Regulatory Purposes (invited paper)

    International Nuclear Information System (INIS)

    Deterministic and probabilistic analyses are used to support applications to regulatory bodies in radiation protection and nuclear safety. The analyses contain uncertainties due to statistical parameter estimations, elements of expert judgement and modelling inaccuracies and incompleteness. It is important that these uncertainties are adequately addressed or analysed in the application. Especially for emergency planning purposes, which are affected by the results of level 3 type probabilistic safety analyses, efforts to assess the uncertainty and its main contributions are useful. Regulatory decision making is an administrative act and cannot be reduced to comparing an outcome of an analysis to given criteria. Though probabilistic analyses are accepted more and more in the nuclear field they unfold their power in regulatory matters in many cases if combined properly with traditional deterministic considerations.

  17. Regulatory T cells in immune-mediated renal disease.

    Science.gov (United States)

    Ghali, Joanna R; Wang, Yuan Min; Holdsworth, Stephen R; Kitching, A Richard

    2016-02-01

    Regulatory T cells (Tregs) are CD4+ T cells that can suppress immune responses by effector T cells, B cells and innate immune cells. This review discusses the role that Tregs play in murine models of immune-mediated renal diseases and acute kidney injury and in human autoimmune kidney disease (such as systemic lupus erythematosus, anti-glomerular basement membrane disease, anti-neutrophil cytoplasmic antibody-associated vasculitis). Current research suggests that Tregs may be reduced in number and/or have impaired regulatory function in these diseases. Tregs possess several mechanisms by which they can limit renal and systemic inflammatory immune responses. Potential therapeutic applications involving Tregs include in vivo induction of Tregs or inducing Tregs from naïve CD4+ T cells or expanding natural Tregs ex vivo, to use as a cellular therapy. At present, the optimal method of generating a phenotypically stable pool of Tregs with long-lasting suppressive effects is not established, but human studies in renal transplantation are underway exploring the therapeutic potential of Tregs as a cellular therapy, and if successful may have a role as a novel therapy in immune-mediated renal diseases.

    Full Text Available OBJECTIVE Analyze the implementation of drug price regulation policy by the Drug Market Regulation Chamber. METHODS This is an interview-based study, which was undertaken in 2012, using semi-structured questionnaires with social actors from the pharmaceutical market, the pharmaceuticals industry, consumers and the regulatory agency. In addition, drug prices were compiled based on surveys conducted in the state of Sao Paulo, at the point of sale, between February 2009 and May 2012. RESULTS The mean drug prices charged at the point of sale (pharmacies were well below the maximum price to the consumer, compared with many drugs sold in Brazil. Between 2009 and 2012, 44 of the 129 prices, corresponding to 99 drugs listed in the database of compiled prices, showed a variation of more than 20.0% in the mean prices at the point of sale and the maximum price to the consumer. In addition, many laboratories have refused to apply the price adequacy coefficient in their sales to government agencies. CONCLUSIONS The regulation implemented by the pharmaceutical market regulator was unable to significantly control prices of marketed drugs, without succeeding to push them to levels lower than those determined by the pharmaceutical industry and failing, therefore, in its objective to promote pharmaceutical support for the public. It is necessary reconstruct the regulatory law to allow market prices to be reduced by the regulator as well as institutional strengthen this government body.

  19. Overview of NRC's human factors regulatory research program

    International Nuclear Information System (INIS)

    The human factors research program is divided into distinct and interrelated program activities: (1) Personnel Performance measurement, (2) Personnel Subsystem, (3) Human-System Interface, (4) Organization and Management, and (5) a group of Reliability Assessment activities. The purpose of the Personnel Performance Measurement activity is to improve the Agency's understanding of the factors influencing personnel performance and the effects on the safety of nuclear operations and maintenance by developing improvements to methods for collecting and managing personnel performance data. Personnel Subsystem research will broaden the understanding of such factors as staffing, qualifications, and training that influence human performance in the nuclear system and will develop the technical basis for regulatory guidance to reduce any adverse impact of these influences on nuclear safety. Research in the Human-System Interface activity will provide the technical basis for ensuring that the interface between the system and the human user supports safe operations and maintenance. Organization and Management research will result in the development of tools for evaluating organization and management issues within the nuclear industry. And finally, the Reliability Assessment group of activities includes multidisciplinary research that will integrate human and hardware considerations for evaluating reliability and risk in NRC licensing, inspection, and regulatory decisions

  7. Regulatory Promotion of Emergent CCS Technology

    Davies, Lincoln; Uchitel, Kirsten; Johnson, David

    2014-01-01

    Despite the growing inevitability of climate change and the attendant need for mitigation strategies, carbon capture and sequestration (CCS) has yet to gain much traction in the United States. Recent regulatory proposals by the U.S. Environmental Protection Agency (EPA), limited in scope to new-build power plants, represent the only significant policy initiative intended to mandate diffusion of CCS technology. Phase I of this Project assessed barriers to CCS deployment as prioritized by the CCS community. That research concluded that there were four primary barriers: (1) cost, (2) lack of a carbon price, (3) liability, and (4) lack of a comprehensive regulatory regime. Phase II of this Project, as presented in this Report, assesses potential regulatory models for CCS and examines where those models address the hurdles to diffusing CCS technology identified in Phase I. It concludes (1) that a CCS-specific but flexible standard, such as a technology performance standard or a very particular type of market-based regulation, likely will promote CCS diffusion, and (2) that these policies cannot work alone, but rather, should be combined with other measures, such as liability limits and a comprehensive CCS regulatory regime.

  8. Regulatory T-cells and autoimmunity.

    LENUS (Irish Health Repository)

    Ni Choileain, Niamh

    2012-02-03

    Approximately 20% of the population is affected by autoimmune or inflammatory diseases mediated by an abnormal immune response. A characteristic feature of autoimmune disease is the selective targeting of a single cell type, organ or tissue by certain populations of autoreactive T-cells. Examples of such diseases include rheumatoid arthritis, insulin-dependent diabetes mellitus, and systemic lupus erythematosus (SLE), all of which are characterized by chronic inflammation, tissue destruction and target organ malfunction. Although strong evidence links most autoimmune diseases to specific genes, considerable controversy prevails regarding the role of regulatory T-cell populations in the disease process. These cells are now also believed to play a key role in mediating transplantation tolerance and inhibiting the induction of tumor immunity. Though the concept of therapeutic immune regulation aimed at treating autoimmune pathology has been validated in many animal models, the development of strategies for the treatment of human autoimmune disorders remains in its infancy. The main obstacles to this include the conflicting findings of different model systems, as well as the contrasting functions of regulatory T-cells and cytokines involved in the development of such disorders. This review examines the role of regulatory T-cells in the pathogenesis of autoimmunity and describes the therapeutic potential of these cells for the prevention of immune-mediated pathologies in the future. Although much remains to be learned about such pathologies, a clearer understanding of the mechanisms by which regulatory T-cells function will undoubtedly lead to exciting new possibilities for immunotherapeutics.

    Science.gov (United States)

    Mendelson, Nina A

    2007-03-01

    Administrative agencies frequently use guidance documents to set policy broadly and prospectively in areas ranging from Department of Education Title IX enforcement to Food and Drug Administration regulation of direct-to- consumer pharmaceutical advertising. In form, these guidances often closely resemble the policies agencies issue in ordinary notice-and-comment rulemaking. However, guidances are generally developed with little public participation and are often immune from judicial review. Nonetheless, guidances can prompt significant changes in behavior from those the agencies regulate. A number of commentators have guardedly defended the current state of affairs. Though guidances lack some important procedural safeguards, they can help agencies supervise low-level employees and supply valuable information to regulated entities regarding how an agency will implement a program. Thus far, however, the debate has largely ignored the distinct and substantial interests of regulatory beneficiaries--those who expect to benefit from government regulation of others. Regulatory beneficiaries include, among others, pharmaceutical consumers, environmental users, and workers seeking safe workplaces. When agencies make policy informally, regulatory beneficiaries suffer distinctive losses to their ability to participate in the agency's decision and to invoke judicial review. This Article argues that considering the interests of regulatory beneficiaries strengthens the case for procedural reform. The Article then assesses some possible solutions. PMID:17410678

    McGowan, Kevin B; Stiegman, Glenn

    2013-01-01

    In the United States, few Food and Drug Administration (FDA)-approved options exist for the treatment of focal cartilage and osteochondral lesions. Developers of products for cartilage repair face many challenges to obtain marketing approval from the FDA. The objective of this review is to discuss the necessary steps for FDA application and approval for a new cartilage repair product. FDA Guidance Documents, FDA Panel Meetings, scientific organization recommendations, and clinicaltrials.gov were reviewed to demonstrate the current thinking of FDA and the scientific community on the regulatory process for cartilage repair therapies. Cartilage repair therapies can receive market approval from FDA as medical devices, drugs, or biologics, and the specific classification of product can affect the nonclinical, clinical, and regulatory strategy to bring the product to market. Recent FDA guidance gives an outline of the required elements to bring a cartilage repair product to market, although these standards are often very general. As a result, companies have to carefully craft their study patient population, comparator group, and clinical endpoint to best showcase their product's attributes. In addition, regulatory strategy and manufacturing process validation need to be considered early in the clinical study process to allow for timely product approval following the completion of clinical study. Although the path to regulatory approval for a cartilage repair therapy is challenging and time-consuming, proper clinical trial planning and attention to the details can eventually save companies time and money by bringing a product to the market in the most expeditious process possible.

  5. Mutational robustness of gene regulatory networks.

    Directory of Open Access Journals (Sweden)

    Aalt D J van Dijk

    Full Text Available Mutational robustness of gene regulatory networks refers to their ability to generate constant biological output upon mutations that change network structure. Such networks contain regulatory interactions (transcription factor-target gene interactions but often also protein-protein interactions between transcription factors. Using computational modeling, we study factors that influence robustness and we infer several network properties governing it. These include the type of mutation, i.e. whether a regulatory interaction or a protein-protein interaction is mutated, and in the case of mutation of a regulatory interaction, the sign of the interaction (activating vs. repressive. In addition, we analyze the effect of combinations of mutations and we compare networks containing monomeric with those containing dimeric transcription factors. Our results are consistent with available data on biological networks, for example based on evolutionary conservation of network features. As a novel and remarkable property, we predict that networks are more robust against mutations in monomer than in dimer transcription factors, a prediction for which analysis of conservation of DNA binding residues in monomeric vs. dimeric transcription factors provides indirect evidence.

    2012-09-01

    Full Text Available Abstract Background Transcription factors regulate numerous cellular processes by controlling the rate of production of each gene. The regulatory relations are modeled using transcriptional regulatory networks. Recent studies have shown that such networks have an underlying hierarchical organization. We consider the problem of discovering the underlying hierarchy in transcriptional regulatory networks. Results We first transform this problem to a mixed integer programming problem. We then use existing tools to solve the resulting problem. For larger networks this strategy does not work due to rapid increase in running time and space usage. We use divide and conquer strategy for such networks. We use our method to analyze the transcriptional regulatory networks of E. coli, H. sapiens and S. cerevisiae. Conclusions Our experiments demonstrate that: (i Our method gives statistically better results than three existing state of the art methods; (ii Our method is robust against errors in the data and (iii Our method’s performance is not affected by the different topologies in the data.

    An increasing number of cis-regulatory RNA elements have been found to regulate gene expression post-transcriptionally in various biological processes in bacterial systems. Effective computational tools for large-scale identification of novel regulatory RNAs are strongly desired to facilitate our exploration of gene regulation mechanisms and regulatory networks. We present a new computational program named RSSVM (RNA Sampler+Support Vector Machine), which employs Support Vector Machines (SVMs) for efficient identification of functional RNA motifs from random RNA secondary structures. RSSVM uses a set of distinctive features to represent the common RNA secondary structure and structural alignment predicted by RNA Sampler, a tool for accurate common RNA secondary structure prediction, and is trained with functional RNAs from a variety of bacterial RNA motif/gene families covering a wide range of sequence identities. When tested on a large number of known and random RNA motifs, RSSVM shows a significantly higher sensitivity than other leading RNA identification programs while maintaining the same false positive rate. RSSVM performs particularly well on sets with low sequence identities. The combination of RNA Sampler and RSSVM provides a new, fast, and efficient pipeline for large-scale discovery of regulatory RNA motifs. We applied RSSVM to multiple Shewanella genomes and identified putative regulatory RNA motifs in the 5' untranslated regions (UTRs) in S. oneidensis, an important bacterial organism with extraordinary respiratory and metal reducing abilities and great potential for bioremediation and alternative energy generation. From 1002 sets of 5'-UTRs of orthologous operons, we identified 166 putative regulatory RNA motifs, including 17 of the 19 known RNA motifs from Rfam, an additional 21 RNA motifs that are supported by literature evidence, 72 RNA motifs overlapping predicted transcription terminators or attenuators, and other candidate regulatory RNA motifs

  15. The impact of measurement errors in the identification of regulatory networks

    2009-12-01

    Full Text Available Abstract Background There are several studies in the literature depicting measurement error in gene expression data and also, several others about regulatory network models. However, only a little fraction describes a combination of measurement error in mathematical regulatory networks and shows how to identify these networks under different rates of noise. Results This article investigates the effects of measurement error on the estimation of the parameters in regulatory networks. Simulation studies indicate that, in both time series (dependent and non-time series (independent data, the measurement error strongly affects the estimated parameters of the regulatory network models, biasing them as predicted by the theory. Moreover, when testing the parameters of the regulatory network models, p-values computed by ignoring the measurement error are not reliable, since the rate of false positives are not controlled under the null hypothesis. In order to overcome these problems, we present an improved version of the Ordinary Least Square estimator in independent (regression models and dependent (autoregressive models data when the variables are subject to noises. Moreover, measurement error estimation procedures for microarrays are also described. Simulation results also show that both corrected methods perform better than the standard ones (i.e., ignoring measurement error. The proposed methodologies are illustrated using microarray data from lung cancer patients and mouse liver time series data. Conclusions Measurement error dangerously affects the identification of regulatory network models, thus, they must be reduced or taken into account in order to avoid erroneous conclusions. This could be one of the reasons for high biological false positive rates identified in actual regulatory network models.

  16. Tank closure reducing grout

    Caldwell, T.B.

    1997-04-18

    A reducing grout has been developed for closing high level waste tanks at the Savannah River Site in Aiken, South Carolina. The grout has a low redox potential, which minimizes the mobility of Sr{sup 90}, the radionuclide with the highest dose potential after closure. The grout also has a high pH which reduces the solubility of the plutonium isotopes. The grout has a high compressive strength and low permeability, which enhances its ability to limit the migration of contaminants after closure. The grout was designed and tested by Construction Technology Laboratories, Inc. Placement methods were developed by the Savannah River Site personnel.

  18. Improving regulatory oversight of maintenance programs

    International Nuclear Information System (INIS)

    Safe nuclear power plant operation requires that risks due to failure or unavailability of Structures, Systems and Components (SSCs) be minimized. Implementation of an effective maintenance program is a key means for achieving this goal. In its regulatory framework, the important relationship between maintenance and safety is acknowledged by the CNSC. A high level maintenance program requirement is included in the Class I Facilities Regulations. In addition, the operating licence contains a condition based on the principle that the design function and performance of SSCs needs to remain consistent with the plant's design and analysis documents. Nuclear power plant licensees have the primary responsibility for safe operation of their facilities and consequently for implementation of a successful maintenance program. The oversight role of the Canadian Nuclear Safety Commission (CNSC) is to ensure that the licensee carries out that responsibility. The challenge for the CNSC is how to do this consistently and efficiently. Three opportunities for improvement to regulatory maintenance oversight are being pursued. These are related to the regulatory framework, compliance verification inspection activities and monitoring of self-reporting. The regulatory framework has been improved by clarifying expectations through the issuance of S-210 'Maintenance Programs for Nuclear Power Plants'. Inspection activities have been improved by introducing new maintenance inspections into the baseline program. Monitoring is being improved by making better use of self-reported and industry produced maintenance related performance indicators. As with any type of program change, the challenge is to ensure the consistent and optimal application of regulatory activities and resources. This paper is a summary of the CNSC's approach to improving its maintenance oversight strategy. (author)

  19. An Analysis of Regulatory Strategies for Recycling and Re-Use of Metals in Australia

    Directory of Open Access Journals (Sweden)

    Wayne Gumley

    2014-04-01

    Full Text Available This article considers regulatory strategies that promote more efficient use of material inputs within the Australian economy, with particular focus on recycling and recovery of metals, drawing upon the concept of a “circular economy”. It briefly reviews the nature of regulation and trends in regulatory strategies within changing policy contexts, and then examines the regulatory framework applicable to the various phases in the life cycle of metals, ranging from extraction of minerals to processing and assimilation of metals into finished products, through to eventual disposal of products as waste. Discussion focuses upon the regulatory strategies applied in each phase and the changing roles of government and business operators within global distribution networks. It is concluded that the prevailing political agenda favoring deregulation and reduced taxation may be a major barrier to development of new styles of regulation and more effective use of taxation powers that is needed to support a more circular economy in metals. The implication for future research is the need to substantiate the outcomes of reflexive regulatory strategies with well-designed empirical studies.

    This correlation study investigated the relationship between nurses' regulatory focus and burnout, as mediated by their perceptions of transformational leadership, using a cross-sectional research design with anonymous questionnaires. In July-August 2012, data were collected from 378 nurses from three hospitals in Shaanxi Province, China, using self-report questionnaires for measuring the nurses' regulatory focus, their level of burnout and their perception of whether the leadership of their supervisor was transformational. Structural equation modelling and bootstrapping procedures were used to identify the mediating effect of their perceptions of transformational leadership. The results supported our hypothesized model. The type of regulatory focus emerged as a significant predictor of burnout. Having a perception of transformational leadership partially mediated the relationship between regulatory focus and burnout. Having a promotion focus reduced burnout when the participants perceived transformational leadership, whereas having a prevention focus exhibited the opposite pattern. The mediating effect of the perception of transformational leadership suggests that a promotion focus may help diminish burnout, directly and indirectly. Nurse managers must be aware of the role of a regulatory focus and cultivate promotion focus in their followers. PMID:24724736

  2. NRC regulatory practices in reactor physics code reviews

    International Nuclear Information System (INIS)

    This paper discusses the process taken by the U.S. Nuclear Regulatory Commission (NRC) in reviewing physics codes and methods. In recent years, because of increased computing storage capability, enhanced computation times, and general progress in analytical techniques and methods, applicants (licensee and vendors), have sought to take advantage of these improvements by asking the NRC staff to review these analytical physics codes and methods. These requests reflect a desire to exploit better methods to provide enhanced computational accuracy and reduce uncertainties, leading to overall improved fuel management core designs and, usually, increased safety margin. This paper describes the review process and gives examples of typical requests for reviews of code improvements and new codes by nuclear power plant licensees and vendors. In addition, it provides examples of the NRC staff technical requirements in evaluating and approving these enhanced codes and methods. Finally, this paper also includes a brief overview of the review process for non-light-water reactors. (authors)

  3. The U.S. Nuclear Regulatory Commission's decommissioning process

    International Nuclear Information System (INIS)

    The term 'Decommission' is defined in the U.S.. Nuclear Regulatory Commission's (USNRC's) regulations at 10 CFR 20.1003 as to remove a facility or site safely from service and reduce residual radioactivity to a level that permits 1) release of the property for unrestricted use and termination of the license; or, 2) release of the property under restricted conditions and the termination of the license. USNRC's decommissioning program encompasses the decommissioning of all NRC licensed facilities, ranging from routine license terminations for sealed source users, to the oversight of complex sites and those on the Site Decommissioning Management Plan (SDMP), as well as power and non-power reactors. This paper describes the USNRC's decommissioning process for materials and reactor facilities and presents an overview of USNRC's decommissioning program activities. (author)

  8. Quality management of the nuclear regulatory body. Peer discussions on regulatory practices

    International Nuclear Information System (INIS)

    This report is the outcome of the ninth series of peer discussions on regulatory practices entitled Nuclear Regulatory Body Quality Management, held in March and May 2001, and which involved the participation of senior nuclear regulators from 23 IAEA Member States. This report conveys the essence of two peer group discussions and highlights some good practices identified by the participating senior regulators. The objective of the discussions was to share experiences of regulatory bodies in implementing QM systems in their own work so as to ensure that the regulatory control over the licensees is effective and efficient and is commensurate with the mandate assigned by their governments. The shared experiences and good practices presented in the report, however, do not necessarily reflect the views of and good practices endorsed by the governments of the nominating Member States, the organizations to which the regulators belong, or the IAEA. The report sets down the peer group's experience in developing, implementing and evaluating QM within their regulatory bodies and identifies points to bear in mind when introducing such a system. This report is structured so that it covers the subject matter under the main headings of: application of quality management to regulatory work; development and implementation of quality management; assessment and improvement of performance; and good practices

    Stereotype threat often incurs the cost of reducing the amount of information that older adults accurately recall. In the current research we tested whether stereotype threat can also benefit memory. According to the regulatory focus account of stereotype threat, threat induces a prevention focus in which people become concerned with avoiding errors of commission and are sensitive to the presence or absence of losses within their environment (Seibt & Förster, 2004). Because of this, we predic...

  12. Regulatory control of radiopharmaceuticals in Tanzania

    International Nuclear Information System (INIS)

    Full text: Millions of nuclear medicine procedures are performed each year worldwide and the demand for radioisotopes is increasing rapidly.The use of radiopharmaceuticals in Tanzania like in many other countries has also been increasing in recent years that necessitates the need for close regulatory control. Their applications in the country started in 1980's in the areas of medical diagnosis and therapy and at present only one center provides such services. This paper describes how radiopharmaceuticals are regulated (radiological point of view) from importation, their use and the management of the resulting radioactive waste. The regulatory framework for nuclear safety, radiation protection and security of radioactive materials was established following the national interest in the area of peaceful applications of nuclear technology. The regulations require that any person intending to import, export or transport any apparatus, article, plant, installation or other material or substance which is a source or intended to be used for the purposes of an undertaking involving the emission of radiation, must apply for a license from the regulatory authority.Radiopharmaceuticals are not produced in the country therefore whoever intends to import, possess and use has to obtain an authorization from the regulatory authority. Licensing requirements include the presence of: Qualified personnel to administer radiopharmaceuticals; Quality Assuarance and Quality Control Programs; Radiation protection measures including emergency planning, preparedness and response; Radioactive waste management program; Written laboratory procedures and safety guidelines. With regard to radioactive waste generated, it is a requirement that waste be managed properly for the protection of personnel, general public and the environment. While liquid wastes are diluted and disposed in a normal sewage system after reaching the respective exemption levels, solids and biological materials are

    Somatic mutations drive cancer and there are established ways to study those in coding sequences. It has been shown that some regulatory mutations are over-represented in cancer. We develop a new strategy to find putative regulatory mutations based on experimentally established motifs for transcription factors (TFs). In total, we find 1,552 candidate regulatory mutations predicted to significantly reduce binding affinity of many TFs in hepatocellular carcinoma and affecting binding of CTCF also in esophagus, gastric, and pancreatic cancers. Near mutated motifs, there is a significant enrichment of (1) genes mutated in cancer, (2) tumor-suppressor genes, (3) genes in KEGG cancer pathways, and (4) sets of genes previously associated to cancer. Experimental and functional validations support the findings. The strategy can be applied to identify regulatory mutations in any cell type with established TF motifs and will aid identifications of genes contributing to cancer. PMID:27174533

  15. Regulatory requirements for the management of radioactive wastes in Argentina

    International Nuclear Information System (INIS)

    Nuclear activity started in Argentina in the early fifties and since then all the peaceful applications of nuclear energy have been developed including nucleo electricity production. In 1994 the organization in charge of the regulatory control of nuclear activities, now the Nuclear Regulatory Authority (ARN), became independent from the organizations related with nuclear promotion (mainly National Atomic Energy Commission, CNEA). Concerning regulatory activities, the regulatory system applied by ARN in Argentina is based on the IAEA's and ICRP's recommendations, adapted to the needs of the country and its own experience gained through more than thirty years of regulatory activities. Besides, specialists from the regulatory organization from Argentina contributed to the development of the recommendations of such organizations. In order to contribute to the understanding of the application of the nuclear regulatory system in Argentina, an overview of the legal and regulatory framework is provided. (author)

One hundred and sixty participants answered an online questionnaire. Three groups were used. The control group did not read any text prior to answering whereas the two experimental groups read either only debunking information or information about the motives of the conspiracists and the fallacy in their reasoning in addition to the debunking paragraph. The second experimental manipulation was effective in reducing medical conspiracy theories beliefs, but not belief in conspiracy theories in general. Neither intervention was effective in increasing the likelihood to have a fictitious child vaccinated. Those not intending to vaccinate a fictitious child endorsed conspiracy theories to a greater degree. A positive correlation between beliefs in conspiracy theories and the experiential/intuitive information processing system was found.

  1. Reducing rotor weight

    1997-12-31

    The cost of energy for renewables has gained greater significance in recent years due to the drop in price in some competing energy sources, particularly natural gas. In pursuit of lower manufacturing costs for wind turbine systems, work was conducted to explore an innovative rotor designed to reduce weight and cost over conventional rotor systems. Trade-off studies were conducted to measure the influence of number of blades, stiffness, and manufacturing method on COE. The study showed that increasing number of blades at constant solidity significantly reduced rotor weight and that manufacturing the blades using pultrusion technology produced the lowest cost per pound. Under contracts with the National Renewable Energy Laboratory and the California Energy Commission, a 400 kW (33m diameter) turbine was designed employing this technology. The project included tests of an 80 kW (15.5m diameter) dynamically scaled rotor which demonstrated the viability of the design.

    2016-10-01

    Mastectomy rates have significantly increased over the last decades, likely due to the rising trend of risk-reducing mastectomies (RRM) in the treatment and prevention of breast cancer. Growing evidence suggests that aggressive risk-reducing surgical strategies are only justified in high-risk breast cancer situations. Notably, in this selected cohort of women, prophylactic mastectomies offer evident benefit for local and contralateral disease control, and may also provide a survival benefit. Nevertheless, the extent of the increasing frequency of this operation is not explained by the broadening of the medical indications alone. Here we analyze the current evidence regarding RRM, its clinical practice, and possible explanations for the rising phenomenon of aggressive surgical locoregional control strategies. PMID:26785281

    We demonstrate how coupling nonlinear dynamical systems can reduce the effects of noise. For simplicity we investigate noisy coupled map lattices. Noise from different lattice nodes can diffuse across the lattice and lower the noise level of individual nodes. We develop a theoretical model that explains this observed noise evolution and show how the coupled dynamics can naturally function as an averaging filter. Our numerical simulations are in excellent agreement with the model predictions.

    Full Text Available The current study investigated whether gradually reducing the frequency of aversive stimuli during extinction can prevent the return of fear. Thirty-one participants of a three-stage procedure (acquisition, extinction and a reinstatement test on day two were randomly assigned to a standard extinction (SE and gradual extinction (GE procedure. The two groups differed only in the extinction procedure. While the SE group ran through a regular extinction process without any negative events, the frequency of the aversive stimuli during the extinction phase was gradually reduced for the GE group. The unconditioned stimulus was an air blast (5 bar, 10 ms. A spider and a scorpion were used as conditioned stimuli. The outcome variables were contingency ratings and physiological measures (skin conductance response and startle response. There were no differences found between the two groups for the acquisition and extinction phases concerning contingency ratings, SCR, or startle response. Gradual extinction compared to standard extinction significantly reduced the return of fear in the reinstatement test for the startle response but not for skin conductance response or contingency ratings. This study was successful in translating the findings in rodent to humans. The results suggest that the gradual extinction process is suitable for increasing the efficacy of fear extinction.

    Practically all medications contain excipients, which are added for the purpose of production enhancement, patient acceptability, improving stability, controlling release etc. Typically excipients are the major components of a drug product, with the active molecule only present in relatively small amounts. Historically, excipients were termed inactive components. However, as highlighted in the present paper; excipients can have an impact on the absorption, distribution, metabolism and elimination (ADME) processes of the co-administered drug, which is important information when selecting excipients for any new formulation. Further, this review also provides a description of the regulatory processes to get new excipients approved in different regions and a discussion of the recent regulatory initiatives, e.g. excipients for paediatric formulations, thereby providing points to consider for the pharmaceutical scientist when selecting excipients for a new drug formulation.

  14. Methodologies for evaluation of AECB regulatory program

    International Nuclear Information System (INIS)

    AECB (Atomic Energy Control Board) commissioned this report to obtain information about methods of planning and conducting evaluation of its regulatory program. The report begins with a bibliography consisting of 280 abstracts assembled from an extensive search of international literature. Each cited publication describes or uses methods applicable to the evaluation of regulatory programs. The report continues with a review of the methodologies found in the literature. It identifies the most relevant references for each step in program evaluation: the commissioning of evaluation; the identification of evaluation issues; the defining of questions; the answering of questions; the reporting of reslts, and the implementation of recommendations. Finally, the report examines the applicability, advantages and disadvantages of the different evaluation methods and makes recommendations about the selection of methods and their application to the AECB program

  15. Regulatory mechanisms link phenotypic plasticity to evolvability.

    Organisms have a remarkable capacity to respond to environmental change. They can either respond directly, by means of phenotypic plasticity, or they can slowly adapt through evolution. Yet, how phenotypic plasticity links to evolutionary adaptability is largely unknown. Current studies of plasticity tend to adopt a phenomenological reaction norm (RN) approach, which neglects the mechanisms underlying plasticity. Focusing on a concrete question - the optimal timing of bacterial sporulation - we here also consider a mechanistic approach, the evolution of a gene regulatory network (GRN) underlying plasticity. Using individual-based simulations, we compare the RN and GRN approach and find a number of striking differences. Most importantly, the GRN model results in a much higher diversity of responsive strategies than the RN model. We show that each of the evolved strategies is pre-adapted to a unique set of unseen environmental conditions. The regulatory mechanisms that control plasticity therefore critically link phenotypic plasticity to the adaptive potential of biological populations. PMID:27087393

  16. Nuclear energy's future: lifting the regulatory cloud

    International Nuclear Information System (INIS)

    Nuclear energy provides 13% of US and 10% of world electricity, with an exemplary safety record and less insult to the environment than any other power source. Walske argues that nuclear power is 15% cheaper than coal despite the high capital and regulatory costs, but regulatory delays in the construction and licensing periods have increased 70% to 10 to 14 years, more than twice the lead time in France and Japan. The long lead time exaggerates the difficulty in forecasting demand, and allows interruptions for fundamental design changes after construction has begun. Walske outlines new legislation for site pre-approval, plant standardization, combined construction and operating licenses, and hybrid procedures for public hearings that would make regulation less uncertain

  17. Considering public confidence in developing regulatory programs

    International Nuclear Information System (INIS)

    In the area of public trust and in any investment, planning and strategy are important. While it is accepted in the United States that an essential part of our mission is to leverage our resources to improving Public Confidence this performance goal must be planned for, managed and measured. Similar to our premier performance goal of Maintaining Safety, a strategy must be developed and integrated with our external stake holders but with internal regulatory staff as well. In order to do that, business is to be conducted in an open environment, the basis for regulatory decisions has to be available through public documents and public meetings, communication must be done in clear and consistent terms.

  19. Regulatory aspects of reactor shutdown systems

    International Nuclear Information System (INIS)

    Provision of shutdown system is primary and essential requirement for ensuring safety of a nuclear reactor. The shutdown function has to be performed reliably and adequately as and when called for. The reactor design must establish and provide the shutdown system with required reactivity worth, the required reactivity insertion rate and assure adequate shutdown margin. Reliability of the shutdown system must be assured by proper system design and by provision of redundancy and diversity. For reliable operation of shutdown system it is essential that the quality assurance requirements are identified and met during all the stages of design, fabrication, commissioning and operation. This paper highlights relevant regulatory requirements laid down by Atomic Energy Regulatory Board (AERB) in its safety codes on design, operation as well as on quality assurance of nuclear power plants. The paper also elaborates some of the activities which should be performed for effective compliance of the requirements. (author)

    The use of predictive modeling in the analysis of gene expression data can greatly accelerate the pace of scientific discovery in biomedical research by enabling in silico experimentation to test disease triggers and potential drug therapies. Techniques that focus on modeling emergence, such as agent-based modeling and multi-agent simulations, are of particular interest as they support the discovery of pathways that may have never been observed in the past. Thus far, these techniques have been primarily applied at the multi-cellular level, or have focused on signaling and metabolic networks. We present an approach where emergence modeling is extended to regulatory networks and demonstrate its application to the discovery of neuroprotective pathways. An initial evaluation of the approach indicates that emergence modeling provides novel insights for the analysis of regulatory networks that can advance the discovery of acute treatments for stroke and other diseases.

    Canada's National Energy Board promotes safety, environmental protection and economic efficiency in the regulation of pipelines, energy development and trade. The Board regulates the design, construction, operation and abandonment of interprovincial and international pipelines within Canada. It also holds regulatory control over tolls and tariffs of interprovincial and international pipelines as well as the export, exploration and development of natural gas and oil resources. Regulatory authorities are required to consult with stakeholders whenever new regulations or amendments to existing regulations are proposed. The Board has launched new initiatives for compliance with Damage Prevention Regulations. Stakeholders were advised through consultative processes such as plain language drafts, open houses, focus meetings and newsletters. The proposed Damage Prevention Regulation will govern activities that have the potential to damage a pipeline. The regulations will apply to pipeline operators, excavators, landowners, municipal planners, emergency responders, and utility companies dealing with federally regulated pipelines. 7 refs., 1 tab.

    Maldonado-Duran, M; Sauceda-Garcia, J M

    1996-01-01

    The authors point out a correlation between regulatory disorders in infants and the problem of excessive crying. The literature describes other behavioral problems involving excessive crying in very young children, but with little emphasis on this association. The recognition and diagnosis of regulatory disorders in infants who cry excessively can help practitioners design appropriate treatment interventions. Understanding these conditions can also help parents tailor their caretaking style, so that they provide appropriate soothing and stimulation to their child. In so doing, they will be better able to develop and preserve a satisfactory parent-child relationship, as well as to maintain their own sense of competence and self-esteem as parents. PMID:8742673

The program main task is the knowledge transfer in the area of nuclear and radiation safety regulations. The lectures of the Program cover the full set of regulatory competencies in compliance with the corresponding IAEA safety standards and they comply with the objectives of the IAEA 'Strategic Approach to Education and Training in Nuclear Safety 2013 - 2022'

  5. Sparsity in Model Gene Regulatory Networks

    International Nuclear Information System (INIS)

    We propose a gene regulatory network model which incorporates the microscopic interactions between genes and transcription factors. In particular the gene's expression level is determined by deterministic synchronous dynamics with contribution from excitatory interactions. We study the structure of networks that have a particular '' function '' and are subject to the natural selection pressure. The question of network robustness against point mutations is addressed, and we conclude that only a small part of connections defined as '' essential '' for cell's existence is fragile. Additionally, the obtained networks are sparse with narrow in-degree and broad out-degree, properties well known from experimental study of biological regulatory networks. Furthermore, during sampling procedure we observe that significantly different genotypes can emerge under mutation-selection balance. All the preceding features hold for the model parameters which lay in the experimentally relevant range. (author)

  7. Attribute Exploration of Gene Regulatory Processes

    CERN Document Server

    Wollbold, Johannes

    2012-01-01

    This thesis aims at the logical analysis of discrete processes, in particular of such generated by gene regulatory networks. States, transitions and operators from temporal logics are expressed in the language of Formal Concept Analysis. By the attribute exploration algorithm, an expert or a computer program is enabled to validate a minimal and complete set of implications, e.g. by comparison of predictions derived from literature with observed data. Here, these rules represent temporal dependencies within gene regulatory networks including coexpression of genes, reachability of states, invariants or possible causal relationships. This new approach is embedded into the theory of universal coalgebras, particularly automata, Kripke structures and Labelled Transition Systems. A comparison with the temporal expressivity of Description Logics is made. The main theoretical results concern the integration of background knowledge into the successive exploration of the defined data structures (formal contexts). Applyi...

  14. Adaptation by Plasticity of Genetic Regulatory Networks

    Science.gov (United States)

    2007-03-01

    Genetic regulatory networks have an essential role in adaptation and evolution of cell populations. This role is strongly related to their dynamic properties over intermediate-to-long time scales. We have used the budding yeast as a model Eukaryote to study the long-term dynamics of the genetic regulatory system and its significance in evolution. A continuous cell growth technique (chemostat) allows us to monitor these systems over long times under controlled condition, enabling a quantitative characterization of dynamics: steady states and their stability, transients and relaxation. First, we have demonstrated adaptive dynamics in the GAL system, a classic model for a Eukaryotic genetic switch, induced and repressed by different carbon sources in the environment. We found that both induction and repression are only transient responses; over several generations, the system converges to a single robust steady state, independent of external conditions. Second, we explored the functional significance of such plasticity of the genetic regulatory network in evolution. We used genetic engineering to mimic the natural process of gene recruitment, placing the gene HIS3 under the regulation of the GAL system. Such genetic rewiring events are important in the evolution of gene regulation, but little is known about the physiological processes supporting them and the dynamics of their assimilation in a cell population. We have shown that cells carrying the rewired genome adapted to a demanding change of environment and stabilized a population, maintaining the adaptive state for hundreds of generations. Using genome-wide expression arrays we showed that underlying the observed adaptation is a global transcriptional programming that allowed tuning expression of the recruited gene to demands. Our results suggest that non-specific properties reflecting the natural plasticity of the regulatory network support adaptation of cells to novel challenges and enhance their evolvability.

  1. Evolution of evolvability in gene regulatory networks.

    Directory of Open Access Journals (Sweden)

    Anton Crombach

    Full Text Available Gene regulatory networks are perhaps the most important organizational level in the cell where signals from the cell state and the outside environment are integrated in terms of activation and inhibition of genes. For the last decade, the study of such networks has been fueled by large-scale experiments and renewed attention from the theoretical field. Different models have been proposed to, for instance, investigate expression dynamics, explain the network topology we observe in bacteria and yeast, and for the analysis of evolvability and robustness of such networks. Yet how these gene regulatory networks evolve and become evolvable remains an open question. An individual-oriented evolutionary model is used to shed light on this matter. Each individual has a genome from which its gene regulatory network is derived. Mutations, such as gene duplications and deletions, alter the genome, while the resulting network determines the gene expression pattern and hence fitness. With this protocol we let a population of individuals evolve under Darwinian selection in an environment that changes through time. Our work demonstrates that long-term evolution of complex gene regulatory networks in a changing environment can lead to a striking increase in the efficiency of generating beneficial mutations. We show that the population evolves towards genotype-phenotype mappings that allow for an orchestrated network-wide change in the gene expression pattern, requiring only a few specific gene indels. The genes involved are hubs of the networks, or directly influencing the hubs. Moreover, throughout the evolutionary trajectory the networks maintain their mutational robustness. In other words, evolution in an alternating environment leads to a network that is sensitive to a small class of beneficial mutations, while the majority of mutations remain neutral: an example of evolution of evolvability.

    Recent regulatory reform has gradually relaxed the constraints on vertical and horizontal diversification of public utilities. After earlier strategies of conglomerate diversification utilities more recently started to expand into domestic and international activities more closely related to their core business. Sound diversification may improve corporate performance, but raises complicated policy issues in firms operating in both regulated and unregulated markets. The paper studies the probl...

    Full Text Available Abstract Background Modeling of cis-elements or regulatory motifs in promoter (upstream regions of genes is a challenging computational problem. In this work, set of regulatory motifs simultaneously present in the promoters of a set of genes is modeled as a biclique in a suitably defined bipartite graph. A biologically meaningful co-occurrence of multiple cis-elements in a gene promoter is assessed by the combined analysis of genomic and gene expression data. Greater statistical significance is associated with a set of genes that shares a common set of regulatory motifs, while simultaneously exhibiting highly correlated gene expression under given experimental conditions. Methods XcisClique, the system developed in this work, is a comprehensive infrastructure that associates annotated genome and gene expression data, models known cis-elements as regular expressions, identifies maximal bicliques in a bipartite gene-motif graph; and ranks bicliques based on their computed statistical significance. Significance is a function of the probability of occurrence of those motifs in a biclique (a hypergeometric distribution, and on the new sum of absolute values statistic (SAV that uses Spearman correlations of gene expression vectors. SAV is a statistic well-suited for this purpose as described in the discussion. Results XcisClique identifies new motif and gene combinations that might indicate as yet unidentified involvement of sets of genes in biological functions and processes. It currently supports Arabidopsis thaliana and can be adapted to other organisms, assuming the existence of annotated genomic sequences, suitable gene expression data, and identified regulatory motifs.
