    Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is the most destructive bacterial disease of rice. The cloned rice gene Xa21 confers resistance to a broad spectrum of Xoo races. To identify genes involved in Xa21-mediated immunity, a whole-genome oligonucleotide microarray of rice was used to profile the expression of rice genes between incompatible interactions and mock treatments at 0, 4, 8, 24, 72 and 120 h post inoculation (hpi) or between incompatible and compatible interactions at 4 hpi, respectively. A total of 441 differentially expressed genes, designated as XDGs (Xa21 mediated differentially expressed genes), were identified. Based on their functional annotations, the XDGs were assigned to 14 categories, including defense-related, signaling, transcriptional regulators. Most of the defense-related genes belonged to the pathogenesis-related gene family, which was induced dramatically at 72 and 120 hpi. Interestingly, most signaling and transcriptional regulator genes were downregulated at 4 and 8 hpi, suggesting that negative regulation of cellular signaling may play a role in the Xa21-mediated defense response. Comparison of expression profiles between Xa21- and other R gene-mediated defense systems revealed interesting common responses. Representative XDGs with supporting evidences were also discussed.

    Receptor-like cytoplasmic kinases (RLCKs) represent a large family of proteins in plants. However, few RLCKs have been well characterized. Here, we report the functional characterization of four rice RLCKs - OsRLCK57, OsRLCK107, OsRLCK118 and OsRLCK176 from subfamily VII. These OsRLCKs interact with the rice brassinosteroid receptor, OsBRI1 in yeast cell, but not the XA21 immune receptor. Transgenic lines silenced for each of these genes have enlarged leaf angles and are hypersensitive to brassinolide treatment compared to wild type rice. Transgenic plants silenced for OsRLCK57 had significantly fewer tillers and reduced panicle secondary branching, and lines silenced for OsRLCK107 and OsRLCK118 produce fewer seeds. Silencing of these genes decreased Xa21 gene expression and compromised XA21-mediated immunity to Xanthomonas oryzae pv. oryzae. Our study demonstrates that these OsRLCKs negatively regulate BR signalling, while positively regulating immune responses by contributing to the expression of the immune receptor XA21. PMID:26679011

    Frankel, Christian; Galland, Jean-Pierre


    This paper focuses on the European Regulatory system which was settled both for opening the Single Market for products and ensuring the consumers' safety. It claims that the New Approach and Standardization, and the Global Approach to conformity assessment, which suppressed the last technical...... barriers to trade in Europe, realized the free movement of products by organizing progressively several orders of markets and regulation. Based on historical and institutional documents, on technical publications, and on interviews, this article relates how the European Commission and the Member States had...... alternatively recourse to markets and to regulations, at the three main levels of the New Approach Directives implementation. The article focuses also more specifically on the Medical Devices sector, not only because this New Approach sector has long been controversial in Europe, and has recently been concerned...

  4. Telomerase Regulation

    Cifuentes-Rojas, Catherine; Dorothy E Shippen


    The intimate connection between telomerase regulation and human disease is now well established. The molecular basis for telomerase regulation is highly complex and entails multiple layers of control. While the major target of enzyme regulation is the catalytic subunit TERT, the RNA subunit of telomerase is also implicated in telomerase control. In addition, alterations in gene dosage and alternative isoforms of core telomerase components have been described. Finally, telomerase localization,...

  5. Radiation regulation

    The five main areas of radiation regulation considered are radiation exposure in the mining of uranium and other minerals, exposure in the use of uranium in nuclear reactors, risks in the transport of radioactive materials and hazards associated with the disposal of used materials. In Australia these problems are regulated by mines departments, the Australian Atomic Energy Commission and radiation control branches in state health departments. Each of these instutional areas of regulation is examined

    Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government. After the watershed passage of the United States Noise Control Act of 1972, other local and state governments passed further regulations. Although the UK and Japan enacted national laws in 1960 and 1967 respectively, these laws were not at all comprehensive or fully enforceable as to address generally rising ambient noise, enforceable...

  7. NORM regulations

    Gray, P. [ed.


    The author reviews the question of regulation for naturally occuring radioactive material (NORM), and the factors that have made this a more prominent concern today. Past practices have been very relaxed, and have often involved very poor records, the involvment of contractors, and the disposition of contaminated equipment back into commercial service. The rationale behind the establishment of regulations is to provide worker protection, to exempt low risk materials, to aid in scrap recycling, to provide direction for remediation and to examine disposal options. The author reviews existing regulations at federal and state levels, impending legislation, and touches on the issue of site remediation and potential liabilities affecting the release of sites contaminated by NORM.

  8. RegulatING chromatin regulators

    Satpathy, Shankha; Nabbi, Arash; Riabowol, Karl


    The five human ING genes encode at least 15 splicing isoforms, most of which affect cell growth, differentiation and apoptosis through their ability to alter gene expression by epigenetic mechanisms. Since their discovery in 1996, ING proteins have been classified as type II tumour suppressors on...... the basis of reports describing their down-regulation and mislocalization in a variety of cancer types. In addition to their regulation by transcriptional mechanisms, understanding the range of PTMs (post-translational modifications) of INGs is important in understanding how ING functions are fine...... stresses. We also describe the ING PTMs that have been identified by several unbiased MS-based PTM enrichment techniques and subsequent proteomic analysis. Among the ING PTMs identified to date, a subset has been characterized for their biological significance and have been shown to affect processes...

  9. Nuclear regulation

    Today, 112 nuclear power plants, 22 facilities that support these plants, 54 reactors used in research, and approximately 23,000 organizations hold licenses from either the Nuclear Regulator Commission or various states to use radioactive material; other facilities are operated by various government agencies. Eventually most of these facilities will be decommissioned, which involves removing the radioactive material and terminating the license. NRC needs to ensure that licensees appropriately decontaminate their facilities because, under current regulations, NRC cannot specifically require additional cleanup once it terminates a license. This paper presents a GAO report on NRC's decommissioning procedures. In two of eight cases GAO reviewed, NRC fully or partially released sites for unrestricted use where radioactive contamination was higher than its guidelines allowed; in the other cases, NRC's information was inadequate or incomplete. Further, NRC lacks information on the types and amounts of radioactive waste buried on-site. At five sites reviewed by GAO, groundwater has been found to be contaminated by radioactive waste

  11. Regulating Rho GTPases and their regulators.

    Hodge, Richard G; Ridley, Anne J


    Rho GTPases regulate cytoskeletal and cell adhesion dynamics and thereby coordinate a wide range of cellular processes, including cell migration, cell polarity and cell cycle progression. Most Rho GTPases cycle between a GTP-bound active conformation and a GDP-bound inactive conformation to regulate their ability to activate effector proteins and to elicit cellular responses. However, it has become apparent that Rho GTPases are regulated by post-translational modifications and the formation of specific protein complexes, in addition to GTP-GDP cycling. The canonical regulators of Rho GTPases - guanine nucleotide exchange factors, GTPase-activating proteins and guanine nucleotide dissociation inhibitors - are regulated similarly, creating a complex network of interactions to determine the precise spatiotemporal activation of Rho GTPases.

  15. Activists versus Captured Regulators

    Daubanes, Julien; Rochet, Jean-Charles


    We analyze the consequences of activism in a regulated industry where the regulator has been captured by the industry. Unlike ordinary economic agents, activists are insensitive to monetary incentives. Moreover, they are less well informed than regulators and their actions generate dead-weight costs. Yet we find that activism may increase social welfare because it disciplines captured regulators and reduces the social cost of imperfect regulatory systems.

  16. Hepcidin: regulation of the master iron regulator


    Iron, an essential nutrient, is required for many diverse biological processes. The absence of a defined pathway to excrete excess iron makes it essential for the body to regulate the amount of iron absorbed; a deficiency could lead to iron deficiency and an excess to iron overload and associated disorders such as anaemia and haemochromatosis respectively. This regulation is mediated by the iron-regulatory hormone hepcidin. Hepcidin binds to the only known iron export protein, ferroportin (FP...

  17. Radiation Control Regulation 1993

    This Regulation (No. 434-1993) was made in pursuance of the Radiation Control Act 1990 and replaces the Active Substances Regulations 1959 repealed by the Act. It entered into force on 1 September 1993. The Regulation specifies that the technical radiation protection definitions have the same meaning as in the 1990 recommendations. The Regulation provides for the licensing of persons to use radioactive substances and radiation apparatus. It prescribes activities which may only be carried out by an accredited radiation expert and regulates the use of radiation apparatus and radioactive substances as well as the disposal and transport of radiation apparatus and radioactive substances.

  18. Views of the regulators

    In dealing with a challenging problem in occupational exposure the nuclear regulator in South Africa concluded that the involvement of stake holders was critical. Valuable lessons were learnt in the process. These related to co-operation amongst regulators, the involvement of regulators in addressing occupational exposure problems, the training of workers by the regulator and the need for technical training of the workers. In general, it was also learnt that regulators should establish mechanisms to measure and continuously improve the satisfaction of their stake holders. (author)

  19. Nuclear safety regulations

    The Nuclear Safety Regulations for Nuclear Installations and Nuclear Safety Codes for Nuclear Pressure Retaining Components were issued by the NNSA in 1995. The Atomic Act and Regulations on the Safety Regulation for Transportation of Radioactive Materials have been finished and submitted to the State Council in 1995. At the same time the NNSA organized a revised collection of regulations on nuclear safety in both Chinese and English, titled 'The Collection of Regulations on Nuclear Safety of the People's Republic of China'. To enhance the implementation of newly issued nuclear safety regulations, the NNSA conducted seven times of propagating activities in relation to the regulations for nuclear pressure retaining components and research reactors design and operating in 1995


    J. GRAF


    This paper proposes a model relationship between the operator engaged in a hazardous activity, the regulator of that activity, and the general public. The roles and responsibilities of each entity are described in a way that allows effective communication flow. The role of the regulator is developed using the steam boiler as an example of a hazard subject to regulation; however, the model applies to any regulated activity. In this model the safety analyst has the extremely important role of communicating sometimes difficult technical information to the regulator in a way that the regulator can provide credible assurance to the general public as to the adequacy of the control of the hazardous activity. The conclusion asserts that acceptance of the model, understanding of the roles and responsibilities and definition of who communicates what information to whom will mitigate frustration on the part of each of the three entities.

  1. The development of regulations

    In October 2002, The Act on Protection Against Ionising Radiation and Nuclear Safety which regulates all aspects of protection against ionising radiation and nuclear safety entered into force in Slovenia. The Slovenian government and its responsible ministries shall issue several governmental and ministerial regulations to support the above - mentioned act. The Slovenian Nuclear Safety Administration (SNSA) which acts within the Ministry of the Environment, Spatial Planing and Energy takes an active part in drafting the regulations which are defined in the act. Due to a very comprehensive and pretentious task, that is to be completed in a relatively short period of time, taking into consideration the involvement of stakeholders and all competent ministries, the SNSA within the Quality Management System developed a special procedure that insures the systematic approach to the preparation of regulations. The article will briefly represent the process that: defines the preparation, development, harmonisation, review, approval and issue of regulations and uniforms the format of developed regulations.

  2. Nuclear safety regulations

    The enactment of nuclear safety regulations in 1996 is mainly focused on the preparation of related regulations, and safety guides for nuclear materials control, the reprocessing installations of spent fuels, the treatment and disposal for radioactive waste. The NNSA also assists the departments concerned of the State Council for modification on the 'Atomic Energy Act' (draft) and the' Regulations on the Safety Supervision and Control of Radioactive Materials Transportation' (draft)

  3. Attention in emotion regulation

    Gelow, Stefan


    The concept of emotion and how to regulate it is a central aspect of modern psychology. Within the process model of emotion regulation (Gross, 1998), one issue is how attentional deployment affects emotion regulation and how this can be measured. In task 1, pictures of positive or negative valence were showed in two conditions, either attend or decrease emotional reaction, while participants’ eye movements were followed with an eye tracker. Ratings of arousal and valence were significantly af...

  5. Emotional regulation and friendship

    Zaccagnini, J.L.; Ruiz-Aranda, D.


    Previous literature has been shown that emotional regulation facilitates the establishment and maintenance of social relations (Dodge Garber, 1991; Saarni, 1999). The objective of the present study was to analyze the influence of emotional regulation (Gross y John, 2003) in positive friendship (Berscheid, 2003), specifically at the level of intimacy with friends. In addition, we examined the mediating role of positive emotions in the relationship between the emotional regulation and the leve...

    Agrell, Per Joakim; Bogetoft, Peter


    Benchmarking methods, and in particular Data Envelopment Analysis (DEA), have become well-established and informative tools for economic regulation. DEA is now routinely used by European regulators to set reasonable revenue caps for energy transmission and distribution system operators. The application of benchmarking in regulation, however, requires specific steps in terms of data validation, model specification and outlier detection that are not systematically documented in open publication...

  10. Reconceptualizing Civil Regulation

    Galang, Roberto Martin; Castello, Itziar


    This article re-conceptualizes the notion of civil regulation, through an analysis of 775 projects by firms located in 21 Asian countries, wherein we map the state of civil regulation initiatives in the region. We challenge two established assumptions in the Corporate Social Responsibility...... literature. First, contrary to what is commonly argued, we claim that strong states in Asia promote civil regulation in what we call the “paradox of the weak state”. Second, we not only argue that civil regulation is mainly enforced by multinational enterprises willing to promote international social and...... environmental standards; but also that local, small and medium companies play a key role in the development of Asian civil regulation. We call this second finding the “CSR importation trap”. Our findings are supported by evidence on the limitations in the interchangeable properties of business and governments...

  11. Regulation of megakaryocytopoiesis.

    Caen, J P; Han, Z C; Bellucci, S; Alemany, M


    After 35 years of research, a physiological regulator of platelet production has been identified and the recombinant protein is available. With the discovery of thrombopoietin (TPO), its potential use in a wide variety of clinical megakaryocytic and platelet disorders has been expected and clinical trials have been undertaken. To date, the reported encouraging pre-clinical studies indicate that, as with erythropoietin or G-CSF, minimal toxicity can be expected. A potential limiting side-effect of TPO could be the induction of thrombosis. Nevertheless, it is too early to know whether this cytokine will be of major therapeutic importance for patients with life-threatening thrombocytopenia, such as patients undergoing bone marrow transplantation or subjected to a high dose of chemotherapy. Several experimental and clinical studies are still needed to determine the efficacy of TPO in the prevention or the amelioration of bleeding, which is the ultimate goal for the appropriate use of cytokines with haemostatic benefit. Basic and clinical studies on regulators of megakaryocytopoiesis have rapidly progressed. Now, there is no doubt that some of these regulators are effective in correcting haematopoietic disorders of various aetiologies. Studies on negative regulators not only are important to understand the regulation of megakaryocytopoiesis in normal and pathological states but also have a potential clinical application. Some of these regulators have been shown to be effective in the treatment of essential thrombocythaemia and other myeloproliferative disorders. Platelet factor 4 (PF4) and some other chemokines are also capable of protecting progenitor cells from the cytotoxicity of chemotherapeutic drugs. However, detailed investigations are still required to determine the precise mechanism(s) of action of these regulators and to establish the optimal clinical protocols of negative regulators alone or in association with positive regulators for the treatment of various

  13. The power of regulation

    Slides accompanying a presentation at The Power of Change Conference in Vancouver, BC in April 1995 about regulations affecting the power industry were presented. Issues addressed included customer choice, incentive regulation changes (price-caps, revenue sharing and pricing flexibility), the reactions of Canadian industry to regulatory changes, and anticipated reactions of the financial markets to changes in regulations. The potential effects of competition and changes that will create competition were discussed. The level of readiness of Canadian financial, ownership and regulatory bodies was discussed. The needs and expectations of investors from a new regulatory regime were quesstimated. Possible alternatives to the present regulatory framework were suggested

    Pagano, Marco; Immordino, Giovanni


    We study regulation of the auditing profession in a model where audit quality is unobservable and enforcing regulation is costly. The optimal audit standard falls short of the first-best audit quality, and is increasing in the riskiness of firms and in the amount of funding they seek. The model can encompass collusion between clients and auditors, arising from the joint provision of auditing and consulting services: deflecting collusion requires less ambitious standards. Finally, banning the ...

    Mossman, Kenneth L.


    Nuclear regulations are a subset of social regulations (laws to control activities that may negatively impact the environment, health, and safety) that concern control of ionizing radiation from radiation-producing equipment and from radioactive materials. The impressive safety record among nuclear technologies is due, in no small part, to the work of radiation safety professionals and to a protection system that has kept pace with the rapid technologic advancements in electric power generati...

  19. Rethinking financial regulation

    Thomas M. Hoenig


    In recent years, revolutionary changes in financial markets, combined with incidents such as Barings and Daiwa, have revived concerns about the adequacy of financial regulation. Historically, financial regulatory policy has been driven by the view that to maintain the health of the financial system you must maintain the health of individual institutions.> In light of ongoing changes in financial markets, however, extending the traditional approach to financial market regulation may not work. ...

    We are interested in evaluating the impact of restrictive planning regulation on entry into the UK grocery retail industry. We estimate a model similar to Bresnahan and Reiss (1991) where we allow for multiple store formats. We find that more restrictive planning regulation reduces the number of large format supermarkets in equilibrium. However, the impact is overstated if variation in demographic characteristics across markets is not also controlled for. Our estimates suggest that restrictiv...

  1. Regulating deregulated energy markets

    The North American gas and electricity markets are fast evolving, and regulators are currently faced with a host of issues such as market-based rates, unbundling, stranded costs, open access, and incentive regulation are surfacing as a result of deregulation. The regulatory environment in Ontario was reviewed by the author. Deregulated markets rule, from commodities to gas and electricity. Additionally, there is an evolution of traditional utility regulation. A look at deregulated markets revealed that there are regulations on boundary conditions on the deregulated market. Under the Ontario Energy Board (OEB), all generators, transmitters, distributors, and retailers of electricity must be licensed. The standard supply service (SSS) offered by electricity distributors and system gas which is still being sold by natural gas distributors continues to be regulated by OEB. One issue that was addressed was separation for revenues and costs of the utility's purchase and sale of gas business, at least for accounting purposes. The next issue discussed was cost of system gas and SSS, followed by timely signals and prudent incurred costs. Historical benefits were reviewed, such as historical commitments to low-cost electricity. Pooling transportation costs, transmission pricing continued, market-based rates, unbundling, stranded costs, open access, incentive regulation/ performance based regulation (PBR) were all discussed. Price cap on PBR, both partial and comprehensive were looked at. A requirement to review guidelines on cost of capital and an application to extend blanket approval provisions for gas storage were discussed, as they are amongst some of the challenges of the future. Other challenges include revised rules and practice and procedure; practice directions for cost awards, appeals, and other functions; confidentiality guidelines; and refinements to the role of and approaches to alternative dispute resolution. The future role of regulators was examined in light

  2. Summary of the regulations

    The International Atomic Energy Agency (IAEA) prescribes regulations for the international movement of all radioactive materials among member nations. The U.S. governmental agencies regulating the transportation of radioactive materals include the Department of Transportation (DOT), which is responsible for safety in packaging, shipping, carriage, stowage, storage, and handling of all radioactive materials; the Nuclear Regulatory Commission (NRC), which is responsible for (1) safety and safeguards in receipt, possession, use, transfer of by-product, source, and special nuclear materials and (2) safety in packaging of fissile and radioactive materials in quantities exceeding Type A limits, defined in the Code of Federal Regulations; the Energy Research and Development Administration, which is responsible for safety in all aspects of radioactive material transport by its license-exempt contractors; and the Postal Service, which is responsible for safety in shipment by mail. Current regulatory actions involving NRC that may influence the transportation of radioactive materials include the examination of the regulations, legal contests, and the adoption of new regulations. The NRC published a draft of an environmental impact statement on transportation in March 1976 and will conduct a rulemaking proceeding after the final version of the statement is published in the fall. Of the new regulations, the most recent innovations in the IAEA regulations and a quality assurance program of increased rigor are foremost. The two most prominent ideas of the reguations IAEA regulations are the assignment of radiotoxicity values to each radionuclide rather than to grups of radionuclides, providing for increased flexibility in package limits for most radionuclides, and the allowance of small releases from Type B packages under hypothetical accident conditions. The DOT and NRC are in the process of adopting these IAEA revisions

  3. Financial Regulation Going Forward

    Franklin Allen; Elena Carletti


    The financial sector is heavily regulated in order to prevent financial crises. The recent crisis showed how ineffective this regulation and other types of government intervention were in achieving this aim. We argue that the crisis was primarily caused by housing price bubbles. These occurred because of too loose monetary policies and the easy availability of credit resulting from the build up of large foreign exchange reserves by Asian central banks. A number of regulatory reforms are sugge...

  4. On Globalisation of Regulation

    Bob Wessels


    Full Text Available In this article the opinion that financial regulation should be dealt with on a national, and not on a global scale is criticised. The objections against global regulation are discussed and dismissed. The greater good of a solid global system is inconsistent with maintaining the full force of national social or economic policies. Bob Wessels submits that the best way forward is to look for (a combination of the best methods of regulation on the basis of geography, the nature of regulation itself (hard law, best practices, guidelines, the function of certain rules in relation to the goals or the expectations they aim to address and the character of these rules. A parallel is drawn with the way in which cross-border insolvencies are regulated, including solutions from practitioners in the global insolvency of Lehman Brothers Group of Companies. Given the essential role courts play the presence of new rules of the international insolvency should be supported by more robust rules for the cross-border judicial coordination of cross-border cases, such as a convention. The body of financial regulation should be guided by international accepted principles and guidelines and international regulation and national implementation should reflect a balance between what is necessary in the light of the past events, while still leaving room for fair national demands and policies. The allocation of clear responsibility and authority to regulating bodies should warrant an efficient and effective answer for what, at the core, is a global problem, related to international financial markets.

  5. Corruption, Institutions and Regulation

    Breen, Michael; Gillanders, Robert


    We analyze the effects of corruption and institutional quality on the quality of business regulation. Our key findings indicate that corruption negatively affects the quality of regulation and that general institutional quality is insignificant once corruption is con- trolled for. These findings hold over a number of specifications which include additional exogenous historical and geographic controls. The findings imply that policy-makers should focus on curbing corruption to improve regulati...

  6. The regulator's viewpoint

    The speaker recalls the task of regulators in establishing criteria and standards and assessing and controlling their fulfillment, as well as the fact that there are many types of radiological regulators, depending on their targets, structures, level of independence, and others. She also stresses that regulators take the environment presently into account to protect people as far as ionising radiation is concerned, that is, environmental protection is provided by present regulations, although implicitly based on an anthropocentric focus. In this sense, there is a clear need to develop a framework for the protection of environment, on the basis of the evolution of the present system. There is a preference for a unique, coherent, timely, integrated and manageable radiological human and environment protection system, which has to be developed internationally. Such an enhanced environmental protection framework needs of clearly defined specific 'bricks' (principles/criteria/tools). Regulators will face important challenges in adapting to an integrated man/environment protection framework, and need to act nationally in the meantime to fulfill obligations, as well as actively encourage international initiatives. A proposal on a radiological environmental framework is laid down, and finally she states the overall regulators viewpoint on this process: 'The path towards pragmatism and credibility'. (author)

  7. Regulating energy industries

    The concept of sector-based regulation takes on significant importance in the context of market liberalization. The overall aim is to conciliate, in the considered sector, fair competition with the achievement of public service missions. However, the nature of the authority in charge of this regulation is not prone to harmonized clauses, even in Europe. For electricity for example, the 96/92/CE directive of 19 December 1996 concerning common rules for the inner electricity market, does not state this and Germany, which has not designed any sector-based regulator, applies the general procedure of litigation settlement by the equivalent of the competition Council. In France, the law Nr 2000-108 of 10 February 2000 defines the CRE (Electricity Regulation Commission) is article 28 as including six members, three of which are appointed by Government and the three others respectively by each of the presidents of the parliamentary assemblies. Many other countries have made the same choice. However, the scope of the missions given to these specialized authorities varies considerably according to the country. At European level, what are the different models of organisation of sector-based regulation in the energy field? How are the new regulators organised in relation with the competition authorities? Will the new models converge on the medium term or on the long term? Must we anticipate the creation of European regulation authorities to rule the problems concerning several national markets? What can we learn from the recent electricity crisis in California? To try and answer these questions, Mr Michel Matheu presented a European comparative study and before the debate started, Mr Pierre Couveinhes suggested a reflection on the practical implications of the analyses carried out.

  8. Nuclear regulation in transition

    The current state of nuclear regulations in the USA is examined. Since Three Mile Island the regulation of the nuclear power industry has been undergoing a noticeable transition. It will be argued here that the transition is characterized by two indicia. First, the primary focus of state and federal regulators has been on the financial aspects of the industry: this is best seen in the context of decisions allocating the costs of nuclear plant cancellations. Second, decisionmaking power has been decentralized: although the regulatory history of nuclear power demonstrates the tradition of centralized decisionmaking power (i.e., formerly the primary decisionmaking body was the Atomic Energy Commission), now States share decisionmaking power with the Nuclear Regulatory Commission. In Section 1 a brief legislative history of nuclear regulation is presented to establish the assertion that nuclear regulation, both de jure and de facto, was centralized. Next, Section 2 canvasses recent United States Supreme Court opinions regarding nuclear regulation. The Court frequently acts as policymaker through the consequences of its opinions, if not by its intent. In the area of nuclear policymaking, the Court has paid allegiance recently both to the tradition of centralization and to the movement toward decentralization. This dualism is reflected in other federal court decisions as well which will be briefly mentioned. Continuing the analysis of Federal regulation, Section 3 examines the current reform efforts of the NRC. Section 4 presents an examination of State responses to nuclear plant cancellations. In this section, State administrative agency and court decisions will be examined and recent State legislation will be discussed. (author)

    Full Text Available Regulating biosystems closely related to human beings are structures still difficult to understand.Numerous intimate processes taking place in these systems, even their actual constitution, are insufficiently decoded, and that they have populated the world long before man invented the first regulator, appears not to have contributed much to their knowledge. This work is intended to highlight what regulating biosystems are.There is no secret that somatic muscles perform control operations which no act of moving would be possible without. All actions are the result of dynamic controlled processes adjusted to strict control laws. By treating them very seriously may lead to knowledge of processes occurring in complex systems

  13. Environmentally regulated aerospace coatings

    Morris, Virginia L.


    Aerospace coatings represent a complex technology which must meet stringent performance requirements in the protection of aerospace vehicles. Topcoats and primers are used, primarily, to protect the structural elements of the air vehicle from exposure to and subsequent degradation by environmental elements. There are also many coatings which perform special functions, i.e., chafing resistance, rain erosion resistance, radiation and electric effects, fuel tank coatings, maskants, wire and fastener coatings. The scheduled promulgation of federal environmental regulations for aerospace manufacture and rework materials and processes will regulate the emissions of photochemically reactive precursors to smog and air toxics. Aerospace organizations will be required to identify, qualify and implement less polluting materials. The elimination of ozone depleting chemicals (ODC's) and implementation of pollution prevention requirements are added constraints which must be addressed concurrently. The broad categories of operations affected are the manufacture, operation, maintenance, and repair of military, commercial, general aviation, and space vehicles. The federal aerospace regulations were developed around the precept that technology had to be available to support the reduction of organic and air toxic emissions, i.e., the regulations cannot be technology forcing. In many cases, the regulations which are currently in effect in the South Coast Air Quality Management District (SCAQMD), located in Southern California, were used as the baseline for the federal regulations. This paper addresses strategies used by Southern California aerospace organizations to cope with these regulatory impacts on aerospace productions programs. All of these regulatory changes are scheduled for implementation in 1993 and 1994, with varying compliance dates established.

  15. Nuclear regulation and safety

    Nuclear regulation and safety are discussed from the standpoint of a hypothetical country that is in the process of introducing a nuclear power industry and setting up a regulatory system. The national policy is assumed to be in favor of nuclear power. The regulators will have responsibility for economic, reliable electric production as well as for safety. Reactor safety is divided into three parts: shut it down, keep it covered, take out the afterheat. Emergency plans also have to be provided. Ways of keeping the core covered with water are discussed

  10. Metabolic regulation of yeast

    Fiechter, A.


    Metabolic regulation which is based on endogeneous and exogeneous process variables which may act constantly or time dependently on the living cell is discussed. The observed phenomena of the regulation are the result of physical, chemical, and biological parameters. These parameters are identified. Ethanol is accumulated as an intermediate product and the synthesis of biomass is reduced. This regulatory effect of glucose is used for the aerobic production of ethanol. Very high production rates are thereby obtained. Understanding of the regulation mechanism of the glucose effect has improved. In addition to catabolite repression, several other mechanisms of enzyme regulation have been described, that are mostly governed by exogeneous factors. Glucose also affects the control of respiration in a third class of yeasts which are unable to make use of ethanol as a substrate for growth. This is due to the lack of any anaplerotic activity. As a consequence, diauxic growth behavior is reduced to a one-stage growth with a drastically reduced cell yield. The pulse chemostat technique, a systematic approach for medium design is developed and medium supplements that are essential for metabolic control are identified.

  11. Regulating emerging technologies

    Full text: The presentation is designed for individuals who are involved in therapeutic administration of radioactive material and the implementation of the radiation safety programme. The United States Nuclear Regulatory Commission (NRC) has regulatory authority over the medical use of by-product material and the radiation from by-product material. The presentation will address how the NRC regulates new medical uses (i.e. emerging technologies) used in radiation oncology that are too new to be covered in the current regulations. NRC's process that allows licensees to get approved for these emerging technologies until regulations are promulgated for the new modalities will be described. The presentation will also cover NRC's reporting requirements for medical events and other radiation safety-related incidents. Some examples of errors that have occurred for these new NRC-regulated activities will be provided. The root causes in these events will be identified to prevent similar additional incidents from occurring in other facilities performing the same type of therapy. (author)

  13. Regulating nuclear fuel waste

    When Parliament passed the Atomic Energy Control Act in 1946, it erected the framework for nuclear safety in Canada. Under the Act, the government created the Atomic Energy Control Board and gave it the authority to make and enforce regulations governing every aspect of nuclear power production and use in this country. The Act gives the Control Board the flexibility to amend its regulations to adapt to changes in technology, health and safety standards, co-operative agreements with provincial agencies and policy regarding trade in nuclear materials. This flexibility has allowed the Control Board to successfully regulate the nuclear industry for more than 40 years. Its mission statement 'to ensure that the use of nuclear energy in Canada does not pose undue risk to health, safety, security and the environment' concisely states the Control Board's primary objective. The Atomic Energy Control Board regulates all aspects of nuclear energy in Canada to ensure there is no undue risk to health, safety, security or the environment. It does this through a multi-stage licensing process

  14. Lysosomal Trafficking Regulator (LYST).

    Ji, Xiaojie; Chang, Bo; Naggert, Jürgen K; Nishina, Patsy M


    Regulation of vesicle trafficking to lysosomes and lysosome-related organelles (LROs) as well as regulation of the size of these organelles are critical to maintain their functions. Disruption of the lysosomal trafficking regulator (LYST) results in Chediak-Higashi syndrome (CHS), a rare autosomal recessive disorder characterized by oculocutaneous albinism, prolonged bleeding, severe immunodeficiency, recurrent bacterial infection, neurologic dysfunction and hemophagocytic lympohistiocytosis (HLH). The classic diagnostic feature of the syndrome is enlarged LROs in all cell types, including lysosomes, melanosomes, cytolytic granules and platelet dense bodies. The most striking CHS ocular pathology observed is an enlargement of melanosomes in the retinal pigment epithelium (RPE), which leads to aberrant distribution of eye pigmentation, and results in photophobia and decreased visual acuity. Understanding the molecular function of LYST and identification of its interacting partners may provide therapeutic targets for CHS and other diseases associated with the regulation of LRO size and/or vesicle trafficking, such as asthma, urticaria and Leishmania amazonensis infections.

  15. Inconsistent Regulators: Evidence From Banking

    Sumit Agarwal; David Lucca; Amit Seru; Francesco Trebbi


    US state chartered commercial banks are supervised alternately by state and federal regulators. Each regulator supervises a given bank for a fixed time period according to a predetermined rotation schedule. We use unique data to examine differences between federal and state regulators for these banks. Federal regulators are significantly less lenient, downgrading supervisory ratings about twice as frequently as state supervisors. Under federal regulators, banks report higher nonperforming loa...

  16. Regulating the private security industry

    Percy, Sarah


    The under-regulation of the private security industry has increasingly become a topic of media and academic interest. This Adelphi Paper enters the debate by explaining why the industry requires further regulation, and what is wrong with the current system. It begins by briefly defining the industry and explaining the need for more effective regulation, before analysing three types of regulation: domestic, international and informal (including self-regulation).

  17. Leadership and the Independent Regulator

    Jamison, Mark A.


    Being a utility regulator has perils because the independence of the regulator necessarily removes power from politicians, operators, and others. Furthermore, regulators are sometimes scapegoats for unpopular policies and unavoidably become involved in shaping the policies that they are supposed to implement. As a result of such frictions, regulators are sometimes removed from office or marginalized in some way. How can regulators not only survive in such an environment, but also thrive? Jami...

  19. Regulation of Meiotic Recombination

    Gregory p. Copenhaver


    Meiotic recombination results in the heritable rearrangement of DNA, primarily through reciprocal exchange between homologous chromosome or gene conversion. In plants these events are critical for ensuring proper chromosome segregation, facilitating DNA repair and providing a basis for genetic diversity. Understanding this fundamental biological mechanism will directly facilitate trait mapping, conventional plant breeding, and development of genetic engineering techniques that will help support the responsible production and conversion of renewable resources for fuels, chemicals, and the conservation of energy (1-3). Substantial progress has been made in understanding the basal recombination machinery, much of which is conserved in organisms as diverse as yeast, plants and mammals (4, 5). Significantly less is known about the factors that regulate how often and where that basal machinery acts on higher eukaryotic chromosomes. One important mechanism for regulating the frequency and distribution of meiotic recombination is crossover interference - or the ability of one recombination event to influence nearby events. The MUS81 gene is thought to play an important role in regulating the influence of interference on crossing over. The immediate goals of this project are to use reverse genetics to identify mutants in two putative MUS81 homologs in the model plant Arabidopsis thaliana, characterize those mutants and initiate a novel forward genetic screen for additional regulators of meiotic recombination. The long-term goal of the project is to understand how meiotic recombination is regulated in higher eukaryotes with an emphasis on the molecular basis of crossover interference. The ability to monitor recombination in all four meiotic products (tetrad analysis) has been a powerful tool in the arsenal of yeast geneticists. Previously, the qrt mutant of Arabidopsis, which causes the four pollen products of male meiosis to remain attached, was developed as a facile system

  20. Volume Regulation in Epithelia

    Larsen, Erik Hviid; Hoffmann, Else Kay


    We review studies on regulatory volume decrease (RVD) and regulatory volume increase (RVI) of major ion and water transporting vertebrate epithelia. The rate of RVD and RVI is faster in cells of high osmotic permeability like amphibian gallbladder and mammalian proximal tubule as compared to...... amphibian skin and mammalian cortical collecting tubule of low and intermediate osmotic permeability. Crosstalk between entrance and exit mechanisms interferes with volume regulation both at aniso-osmotic and iso-osmotic volume perturbations. It has been proposed that cell volume regulation is an intrinsic...... function of iso-osmotic fluid transport that depends on Na+ recirculation. The causative relationship is discussed for a fluid-absorbing and a fluid-secreting epithelium of which the Na+ recirculation mechanisms have been identified. A large number of transporters and ion channels involved in cell volume...

  3. Human telomerase activity regulation

    Wojtyla, Aneta; Gladych, Marta; Rubis, Blazej


    Telomerase has been recognized as a relevant factor distinguishing cancer cells from normal cells. Thus, it has become a very promising target for anticancer therapy. The cell proliferative potential can be limited by replication end problem, due to telomeres shortening, which is overcome in cancer cells by telomerase activity or by alternative telomeres lengthening (ALT) mechanism. However, this multisubunit enzymatic complex can be regulated at various levels, including expression control b...

  6. Gastrointestinal hormones regulating appetite

    Chaudhri, Owais; Small, Caroline; Bloom, Steve


    The role of gastrointestinal hormones in the regulation of appetite is reviewed. The gastrointestinal tract is the largest endocrine organ in the body. Gut hormones function to optimize the process of digestion and absorption of nutrients by the gut. In this capacity, their local effects on gastrointestinal motility and secretion have been well characterized. By altering the rate at which nutrients are delivered to compartments of the alimentary canal, the control of food intake arguably cons...

    Holding the news media accountable has traditionally been a task of the state in Jordan. Media laws and regulations are numerous and do not leave too much space for self-regulatory practices on a national basis. The Jordan Press Association (JPA) is the core of so-called established media accountability institutions. It conducted a law-like code of ethics in 2003 and runs ombuds committees (currently three) dealing with mishaps of the media to prevent journalists from legal liability. Thou...

  11. Improving CS regulations.

    Nesse, R.J.; Scheer, R.M.; Marasco, A.L.; Furey, R.


    President Carter issued Executive Order 12044 (3/28/78) that required all Federal agencies to distinguish between significant and insignificant regulations, and to determine whether a regulation will result in major impacts. This study gathered information on the impact of the order and the guidelines on the Office of Conservation and Solar Energy (CS) regulatory practices, investigated problems encountered by the CS staff when implementing the order and guidelines, and recommended solutions to resolve these problems. Major tasks accomplished and discussed are: (1) legislation, Executive Orders, and DOE Memoranda concerning Federal administrative procedures relevant to the development and analysis of regulations within CS reviewed; (2) relevant DOE Orders and Memoranda analyzed and key DOE and CS staff interviewed in order to accurately describe the current CS regulatory process; (3) DOE staff from the Office of the General Counsel, the Office of Policy and Evaluation, the Office of the Environment, and the Office of the Secretary interviewed to explore issues and problems encountered with current CS regulatory practices; (4) the regulatory processes at five other Federal agencies reviewed in order to see how other agencies have approached the regulatory process, dealt with specific regulatory problems, and responded to the Executive Order; and (5) based on the results of the preceding four tasks, recommendations for potential solutions to the CS regulatory problems developed.

  13. Taiwan Regulation of Biobanks.

    Fan, Chien-Te; Hung, Tzu-Hsun; Yeh, Chan-Kun


    This paper introduces legal framework and governance structure in relation to the management and development of biobanks in Taiwan. At first, we briefly describe Taiwan's population, political system and health care system. Secondly, this research introduces biobanking framework of Taiwan including 25 biobanks established with the approval of the Ministry of Health and Welfare. In those biobanks, "Taiwan Biobank" is the first and the largest government-supported biobank which comprises population-based cohort study and disease- oriented study. Since the collection of information, data, and biological specimen of biobanks often involve highly sensitive personal information, in the legal framework of Taiwan, there is a specific regulation, "Human Biobank Management Act" (HBMA), which plays an important role in regulating biobanks in Taiwan. HBMA, the Personal Information Act and other regulations constitute a comprehensive legal and regulatory privacy framework of biobanks. Through the introduction and analysis of the current legal framework applicable to biobanks, we found that there are several challenges that need to be solved appropriately that involve duplicate review systems, the obstacles in the international collaboration, and data sharing between biobanks in Taiwan.

  14. Whither tobacco product regulation?

    McNeill, Ann; Hammond, David; Gartner, Coral


    Despite decades of industry innovation and regulatory efforts, the harmfulness of conventional cigarettes has not changed. There are several pitfalls in this area, including the long time lag before health impacts of product regulatory changes become apparent, the danger of consumers deriving false reassurance of lesser harm in the interim period, the lack of relevant expertise and the lack of an internationally agreed and evidence-based strategic approach. Articles 9 and 10 of the Framework Convention on Tobacco Control provide the potential for such a global strategy, and knowledge and research has increased significantly over recent years. However, there are huge opportunity costs in implementing product disclosure and regulatory strategies: most national regulators have very limited human and financial resources, which should be focused on other evidence-based tobacco control interventions. We believe therefore that it is now time to abandon the notion of safe or safer cigarettes while moving consumers towards cleaner nicotine products as soon as possible. In parallel to this, we recommend a number of other strategies be implemented including: reducing the appeal of all tobacco products, forbidding new tobacco products or brand variants being marketed without evidence of reduced harm, appeal or addictiveness, and developing a tobacco industry resourced, but industry independent, Framework Convention on Tobacco Control global repository to assist national regulators in understanding and regulating the products on their markets.

  15. The international radioactive transportation regulations: A model for national regulations

    The International Atomic Energy Agency's (IAEA) Regulations for the Safe Transport of Radioactive Material, Safety Series No. 6 (herein after denoted as the ''International Regulations'') serve as the model for the regulations for individual countries and international modal organizations controlling the packaging and transportation of radioactive materials. The purpose of this paper is to outline the background and history of the International Regulations, the general principles behind the requirements of the International Regulations, the structure and general contents of the latest edition of the International Regulations, and the roles of various international bodies in the development and implementation of the International Regulations and the current status of regulatory and supportive document development at both the international and domestic level. This review will provide a basis for users and potential users to better understand the source and application of the International Regulations. 1 tab

  16. Nuclear regulation in 2000

    A key prerequisite to the development of a nuclear program to provide a country's electricity is that governments and the public are confident that a nuclear accident 'will not occur' over the whole life of the program. This can only be achieved by three elements being equally strong: an excellent design, a highly competent and safety conscious operator, and a strong competent regulator with appropriate legal powers. This paper will outline what is necessary to achieve the third of these prerequisites. It will outline the principles by which a Regulatory Agency ensures that licensees meet their responsibility for the safety of their nuclear plant, based on both internationally accepted ideas, the Nuclear Safety Convention, and Canadian practice. The paper will cover legislative principles -- what to include in legislation, what to include in regulations, and what to include in standards and guides. The problem of 'prescriptive requirements' versus 'general performance statements' in regulations will be addressed, and the implications of this problem on ensuring licensees retain responsibility for safety, and on licensees' desire for a high degree of certainty in what is expected of them, both to get a licence and to keep it, in today's economic climate. The paper will also address compliance and the differences between the lawyers' definition of compliance (meeting specific requirements defined by law) and the nuclear safety engineers' view of compliance, (meeting commitments made at the time a licence was given), and how these views can be reconciled. The paper will discuss how Canada's new Nuclear Safety and Control Act has addressed some of these issues, and how the Canadian Nuclear Safety Commission is implementing the new Act. The issue of transfer of regulatory programs and technology to the regulatory agencies of countries buying a nuclear plant from Canadian companies will be discussed, and examples given of how this has been accomplished to the benefit of

  9. [Regulation of terpene metabolism

    Croteau, R.


    During the last grant period, we have completed studies on the key pathways of monoterpene biosynthesis and catabolism in sage and peppermint, and have, by several lines of evidence, deciphered the rate-limiting step of each pathway. We have at least partially purified and characterized the relevant enzymes of each pathway. We have made a strong case, based on analytical, in vivo, and in vitro studies, that terpene accumulation depends upon the balance between biosynthesis and catabolism, and provided supporting evidence that these processes are developmentally-regulated and very closely associated with senescence of the oil glands. Oil gland ontogeny has been characterized at the ultrastructural level. We have exploited foliar-applied bioregulators to delay gland senescence, and have developed tissue explant and cell culture systems to study several elusive aspects of catabolism. We have isolated pure gland cell clusters and localized monoterpene biosynthesis and catabolism within these structures, and have used these preparations as starting materials for the purification to homogeneity of target regulatory'' enzymes. We have thus developed the necessary background knowledge, based on a firm understanding of enzymology, as well as the necessary experimental tools for studying the regulation of monoterpene metabolism at the molecular level. Furthermore, we are now in a position to extend our systematic approach to other terpenoid classes (C[sub 15]-C[sub 30]) produced by oil glands.

  10. Regulation of ATM induction

    Full text: ATM, the tumour suppressor protein mutated in ataxia-telangiectasia, is of pivotal importance in controlling the cells primary response to ionising radiation (IR) induced DNA damage. Mutations in ATM which reduce the level of the ATM protein and/or compromise ATM functions are known to give rise to radiosensitivity and defective cell cycle checkpoint control. In response to DNA damage ATM kinase is rapidly activated and initiates downstream signalling to cell cycle control molecules including p53. To investigate additional mechanisms of ATM control we have employed ATM antisense expression in cultured cells, western analyses and immunohistochemistry in situ. We report that ATM can be up-regulated up to 10-fold following exposure to low levels of ionising radiation. ATM radiation-induction was radiation dose dependent while the rapidity of the response indicates a post translational pathway. The concurrent time frames for the radiation-induction of ATM levels and the activation of ATM kinase activity appear to be complimentary in boosting ATM's protective response to IR induced DNA damage, especially in ATM 'low expressing' systems. We also provide the first report of ATM misregulation in 2 cancer patients, indicating that ATM is not only radio-protective but has possible implications in cancer, particularly breast cancer. These results have particular importance in defining the regulation of the ATM protein as an: adaptive radio-response; radio-prognostic market in tumours and normal tissue, and breast cancer marker

  11. Regulation as delegation

    Oren Bar-Gill


    Full Text Available Objective to consider the conception of reverse delegation when the government acts a principal and an individual ndash an agent from the point of view of behavioral PrincipalAgent Theory. Methods statistical method sociological polling. Results In diverse areas ndash from retirement savings to consumer credit to prescription drug use to fuel economy and energy efficiency rules to tobacco consumption to food and beverage consumption ndash government makes decisions for us or endeavors to help us make better decisions thus serving as our agent. From the point of view of PrincipalAgent Theory and behavioral PrincipalAgent Theory a great deal of modern regulation can be helpfully evaluated as a hypothetical delegation. Shifting from personal decisions to public goods problems the authors view the idea of reverse delegation with the government as principal and the individuals as agents. They show that the essence of delegation changes depending on the context. The article describes conditions under which various approaches will make sense. Scientific novelty the paper is devoted to the foreign experience of regulation through delegation by the example of a country with developed market economy the USA. It shows the prospects of such approach in solving both the public and the private tasks. Application of PrincipalAgent Theory and behavioral PrincipalAgent Theory is viewed to distinguish between such types of hypothetical delegation as information default rules incentives precommitments mandates and prohibitions. The article considers the benefits and costs of delegation and circumstances in which one or another approach makes sense. Practical significance PrincipalAgent Theory is widely used in economics and political science and can serve as a convenient tool to consider the optimal scale and essence of the assistance rendered to us by the government as our agent. The paper is of interest for the Russian legal science as the institution of

  13. NCAM regulates cell motility

    Prag, Søren; Lepekhin, Eugene A; Kolkova, Kateryna;


    Cell migration is required during development of the nervous system. The regulatory mechanisms for this process, however, are poorly elucidated. We show here that expression of or exposure to the neural cell adhesion molecule (NCAM) strongly affected the motile behaviour of glioma cells...... independently of homophilic NCAM interactions. Expression of the transmembrane 140 kDa isoform of NCAM (NCAM-140) caused a significant reduction in cellular motility, probably through interference with factors regulating cellular attachment, as NCAM-140-expressing cells exhibited a decreased attachment to a...... fibronectin substratum compared with NCAM-negative cells. Ectopic expression of the cytoplasmic part of NCAM-140 also inhibited cell motility, presumably via the non-receptor tyrosine kinase p59(fyn) with which NCAM-140 interacts. Furthermore, we showed that the extracellular part of NCAM acted as a paracrine...

  14. Views of the regulators

    It is important to remember what the concept and objective of optimization are and the role of dose constraints. In relation to exposures from any particular source within a practice, radiation protection shall be optimized so that the magnitude of individual doses, except for therapeutic medical exposures, the number of exposed people and the likelihood of incurring exposures will all be kept 'as low as reasonably achievable' (ALARA), economic and social factors being taken into account, within the restriction that the dose to individuals delivered by the source be subject to dose constraints. Dose constraints and dose limits to occupational exposures are necessary since the workers are not the direct beneficiaries of the exposures and the optimization procedures based on collective doses could result in inequities. The dose constraint has the secondary function of ensuring that the sum of the doses that an individual received from different practices to which the individual can be exposed does not exceed the dose limit. Before discussing co-operation, it is fundamental to provide a description of the role and responsibilities of the regulatory authority, employers and workers. The role and responsibilities of the regulatory authority in establishing regulations, granting authorizations, undertaking inspections, ensuring enforcement, and dealing with accidents and emergencies are set by the national legislation. To achieve this objective, the licensee is required to use, to the extent practicable, procedures and engineering controls that are based upon sound radiation protection and safety principles. The regulations establish that the licensees and employers of workers who are engaged in activities that involve or could involve occupational exposure shall be responsible for the protection of these workers against any occupational exposure that is not excluded from regulatory control

  15. TFEB regulates lysosomal proteostasis.

    Song, Wensi; Wang, Fan; Savini, Marzia; Ake, Ashley; di Ronza, Alberto; Sardiello, Marco; Segatori, Laura


    Loss-of-function diseases are often caused by destabilizing mutations that lead to protein misfolding and degradation. Modulating the innate protein homeostasis (proteostasis) capacity may lead to rescue of native folding of the mutated variants, thereby ameliorating the disease phenotype. In lysosomal storage disorders (LSDs), a number of highly prevalent alleles have missense mutations that do not impair the enzyme's catalytic activity but destabilize its native structure, resulting in the degradation of the misfolded protein. Enhancing the cellular folding capacity enables rescuing the native, biologically functional structure of these unstable mutated enzymes. However, proteostasis modulators specific for the lysosomal system are currently unknown. Here, we investigate the role of the transcription factor EB (TFEB), a master regulator of lysosomal biogenesis and function, in modulating lysosomal proteostasis in LSDs. We show that TFEB activation results in enhanced folding, trafficking and lysosomal activity of a severely destabilized glucocerebrosidase (GC) variant associated with the development of Gaucher disease (GD), the most common LSD. TFEB specifically induces the expression of GC and of key genes involved in folding and lysosomal trafficking, thereby enhancing both the pool of mutated enzyme and its processing through the secretory pathway. TFEB activation also rescues the activity of a β-hexosaminidase mutant associated with the development of another LSD, Tay-Sachs disease, thus suggesting general applicability of TFEB-mediated proteostasis modulation to rescue destabilizing mutations in LSDs. In summary, our findings identify TFEB as a specific regulator of lysosomal proteostasis and suggest that TFEB may be used as a therapeutic target to rescue enzyme homeostasis in LSDs. PMID:23393155

  16. [Regulation of terpene metabolism

    Croteau, R.


    Terpenoid oils, resins, and waxes from plants are important renewable resources. The objective of this project is to understand the regulation of terpenoid metabolism using the monoterpenes (C[sub 10]) as a model. The pathways of monoterpene biosynthesis and catabolism have been established, and the relevant enzymes characterized. Developmental studies relating enzyme levels to terpene accumulation within the oil gland sites of synthesis, and work with bioregulators, indicate that monoterpene production is controlled by terpene cyclases, the enzymes catalyzing the first step of the monoterpene pathway. As the leaf oil glands mature, cyclase levels decline and monoterpene biosynthesis ceases. Yield then decreases as the monoterpenes undergo catabolism by a process involving conversion to a glycoside and transport from the leaf glands to the root. At this site, the terpenoid is oxidatively degraded to acetate that is recycled into other lipid metabolites. During the transition from terpene biosynthesis to catabolism, the oil glands undergo dramatic ultrastructural modification. Degradation of the producing cells results in mixing of previously compartmentized monoterpenes with the catabolic enzymes, ultimately leading to yield decline. This regulatory model is being applied to the formation of other terpenoid classes (C[sub 15] C[sub 20], C[sub 30], C[sub 40]) within the oil glands. Preliminary investigations on the formation of sesquiterpenes (C[sub 15]) suggest that the corresponding cyclases may play a lesser role in determining yield of these products, but that compartmentation effects are important. From these studies, a comprehensive scheme for the regulation of terpene metabolism is being constructed. Results from this project wail have important consequences for the yield and composition of terpenoid natural products that can be made available for industrial exploitation.

  17. Regulation of the power sector


    Regulation of the Power Sector is a unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems. The need for generation to occur at the time of use occasioned by the impracticality of large-scale electricity storage coupled with constant and often unpredictable changes in demand make electricity-supply systems large, dynamic and complex and their regulation a daunting task. Conceptually arranged in four parts, this book addresses both traditional regulatory frameworks and also liberalized and re-regulated environments. First, an introduction gives a full characterization of power supply including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation and the third looks at the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute form the content of the fourth part. In a sector where regulatory design is the key driver...

  19. Regulation of sphingomyelin metabolism.

    Bienias, Kamil; Fiedorowicz, Anna; Sadowska, Anna; Prokopiuk, Sławomir; Car, Halina


    Sphingolipids (SFs) represent a large class of lipids playing diverse functions in a vast number of physiological and pathological processes. Sphingomyelin (SM) is the most abundant SF in the cell, with ubiquitous distribution within mammalian tissues, and particularly high levels in the Central Nervous System (CNS). SM is an essential element of plasma membrane (PM) and its levels are crucial for the cell function. SM content in a cell is strictly regulated by the enzymes of SM metabolic pathways, which activities create a balance between SM synthesis and degradation. The de novo synthesis via SM synthases (SMSs) in the last step of the multi-stage process is the most important pathway of SM formation in a cell. The SM hydrolysis by sphingomyelinases (SMases) increases the concentration of ceramide (Cer), a bioactive molecule, which is involved in cellular proliferation, growth and apoptosis. By controlling the levels of SM and Cer, SMSs and SMases maintain cellular homeostasis. Enzymes of SM cycle exhibit unique properties and diverse tissue distribution. Disturbances in their activities were observed in many CNS pathologies. This review characterizes the physiological roles of SM and enzymes controlling SM levels as well as their involvement in selected pathologies of the Central Nervous System, such as ischemia/hypoxia, Alzheimer disease (AD), Parkinson disease (PD), depression, schizophrenia and Niemann Pick disease (NPD).

  20. Self-Regulated Reionization

    Iliev, I T; Shapiro, P R; Pen, U L; Iliev, Ilian T.; Mellema, Garrelt; Shapiro, Paul R.; Pen, Ue-Li


    Recently, we have presented the first large-scale radiative transfer simulations of reionization. Here we present new simulations which extend the source halo mass range downward to 10^8M_solar, to capture the full range of halo masses thought to be primarily responsible for reionization by their star formation following atomic hydrogen radiative cooling and gravitational collapse. Haloes below about 10^9M_solar, however, are subject to Jeans-mass filtering in the ionized regions, which suppresses their baryonic content and their ability to release ionizing radiation. By including these smaller-mass haloes but accounting for their suppression, too, we find that reionization is ``self-regulating,'' as follows. As the mean ionized fraction rises, so does the fraction of the volume within which suppression occurs. Hence, the degree of suppression is related to the mean ionized fraction. Since low-mass haloes with high emissivity achieve a given mean ionized fraction earlier than do those with low efficiency, Jea...

  1. Between regulation and independence

    This article stresses, first, on the differences between electricity and gas in terms of storability and place of production before introducing the gas sector and its reorganization and re-structuration in the framework of energy markets deregulation. Then, it presents the actions carried out by the commission of energy regulation (CRE) intended to improve the operation of the gas market: improvement of transparency, incitation to invest in transportation infrastructures, organisation of the downstream market and development of regional gas markets. Since July 1, 2007, the opening of gas market is juridically and technically complete. The role of CRE is also to inform the consumers and to warrant a non-discriminatory access to infrastructures in a context of sound competition. On this point, the new situation is satisfactory but improvements are needed to increase the offer. The future objectives of CRE is to maintain a climate favorable to investments, to implement stable and efficient conditions of access to infrastructures and, finally, to regularly work at the European scale for the building up of a domestic gas market synonymous of security of supplies, sustainable development and competitiveness.

    Edward Simpson Prescott


    Auditing is introduced into a model of bank capital regulation. Deterministic and stochastic auditing strategies are studied. Contrary to intuition, auditing of bank risk should be focused on the safest banks because they hold the least amount of capital. Risky banks, which hold more capital, need to be audited less. The importance of auditing by regulators and penalties for non-compliance are discussed in light of the Basel II capital regulation proposals. Emphasis is placed on the importanc...

  9. The next restructuring: Environmental regulation

    From oil, to natural gas, and now electricity, the regulation of energy markets has been successively restructured to allow greater scope to market forces. The likely next domain for restructuring, environmental regulation, may seem far-fetched now, but it is no more so than the restructuring of electric utility regulation would have seemed to be twenty years ago. The grand experiment with emissions trading under the US acid rain program has set a propitious example by showing that markets in environmental goods can be constructed and that the explicit recognition of property rights in the use of the environment is compatible with effective and non-intrusive environmental regulation

Ripple voltage is less than 20 mV, transient recovery time is less than 50 ms. Parallel MOSFET's act as high-current dc regulator and switch. Regulator can be used wherever large direct currents must be controlled. Can be applied to inverters, industrial furnaces photovoltaic solar generators, dc motors, and electric autos.

  12. Regulation of electricity prices?

    In this paper author deals with the regulation of electricity prices in the Slovak Republic. Author contests the social policy of the government through doped prices of electricity. Two thirds of electricity is generated in nuclear power plants in Slovakia. Hence, it is necessary to focus on the solution of problem of nuclear waste. In 2004 Ministry of Economy stated, that the deficit in nuclear fund, from which the country have to fully cover the costs of liquidation and final disposal of nuclear waste, is estimated in the amount of around 89 billion Slovak crowns (≅ 3.7 billion $). From it, so called historical deficit, which originated because of late foundation of fund, represents officially 15 billion Slovak crowns (≅ 0.62 billion $). In Slovakia exists the real risk, that by maintenance of present state by creation and draw of the fund, it will be possible to ensure only 39 per cent of financial sources necessary for full financial handling of the back part of nuclear energetic. Even though the Ministry of Economy in connection with privatisation of Slovenske elektrarne designed to decrease the transfers of operators of nuclear power plants into nuclear fund. In 2006 the Parliament decreased by the law the level of gains of the fund from sale of nuclear electricity (the second from two components of the gains of the fund) from 6.8 to 5.95 per cent from annual revenues. So the tax of forced reduction of the price of nuclear electricity will be represented by loading of the further generations

  13. Views of the regulators

    The International Commission on Radiological Protection (ICRP) offers its recommendations to regulatory and advisory bodies and provides advice to help management and professional staff with responsibility for radiation protection. The ICRP has no formal power to impose its proposals. However, legislation and regulations in most countries adhere closely to ICRP recommendations. The recommendations of the ICRP are based upon the fundamental principles and quantitative bases upon which appropriate radiation protection measures can be established. The radiation protection system recommended by the ICRP in its Publication 60 is based upon: (a) Justification principle: A practice or an activity that involves ionizing radiation exposure is justified if the anticipated benefit is greater than the risk incurred. (b) Optimization principle: All exposures from justified practices shall be kept as low as reasonably achievable (ALARA), economic and social factors being taken into account. (c) Individual dose and risk limits: Individual doses resulting from all relevant practices shall be subject to dose limits and risk limits in cases where potential exposures are likely. To manage risks, three levels are usually distinguished: unacceptable risk, tolerable risk and acceptable risk. The aim of radiation protection is to reduce the radiation exposure level to below that designated as having unacceptable risk. When radiation protection is optimized, the residual risk level becomes acceptable. Any additional measure is ineffective both from economic and social points of view. Regulatory limits adopted from ICRP recommendations are set such that continued exposure at a dose just above the limit would be unacceptable on any reasonable ground. Continued exposure at a level just below the dose limit might be tolerated but would not be welcome. Acceptable doses are those that are below the limit. Individual doses are only acceptable if they are optimized

    Silencing of splicing regulators by RNA interference, combined with splicing-specific microarrays, has revealed a complex network of distinct alternative splicing events in Drosophila, while a high-throughput screen of more than 6,000 compounds has identified drugs that interfere specifically and directly with one class of splicing regulators in human cells.

  20. RNA-guided transcriptional regulation

    Church, George M.; Mali, Prashant G.; Esvelt, Kevin M.


    Methods of modulating expression of a target nucleic acid in a cell are provided including introducing into the cell a first foreign nucleic acid encoding one or more RNAs complementary to DNA, wherein the DNA includes the target nucleic acid, introducing into the cell a second foreign nucleic acid encoding a nuclease-null Cas9 protein that binds to the DNA and is guided by the one or more RNAs, introducing into the cell a third foreign nucleic acid encoding a transcriptional regulator protein or domain, wherein the one or more RNAs, the nuclease-null Cas9 protein, and the transcriptional regulator protein or domain are expressed, wherein the one or more RNAs, the nuclease-null Cas9 protein and the transcriptional regulator protein or domain co-localize to the DNA and wherein the transcriptional regulator protein or domain regulates expression of the target nucleic acid.

  1. Regulation of gas infrastructure expansion

    The topic of this dissertation is the regulation of gas infrastructure expansion in the European Union (EU). While the gas market has been liberalised, the gas infrastructure has largely remained in the regulated domain. However, not necessarily all gas infrastructure facilities - such as gas storage facilities, LNG import terminals and certain gas transmission pipelines - need to be regulated, as there may be scope for competition. In practice, the choice of regulation of gas infrastructure expansion varies among different types of gas infrastructure facilities and across EU Member States. Based on a review of economic literature and on a series of in-depth case studies, this study explains these differences in choices of regulation from differences in policy objectives, differences in local circumstances and differences in the intrinsic characteristics of the infrastructure projects. An important conclusion is that there is potential for a larger role for competition in gas infrastructure expansion.

  2. Strategic automation of emotion regulation.

    Gallo, Inge Schweiger; Keil, Andreas; McCulloch, Kathleen C; Rockstroh, Brigitte; Gollwitzer, Peter M


    As implementation intentions are a powerful self-regulation tool for thought and action (meta-analysis by P. M. Gollwitzer & P. Sheeran, 2006), the present studies were conducted to address their effectiveness in regulating emotional reactivity. Disgust- (Study 1) and fear- (Study 2) eliciting stimuli were viewed under 3 different self-regulation instructions: the goal intention to not get disgusted or frightened, respectively, this goal intention furnished with an implementation intention (i.e., an if-then plan), and a no-self-regulation control group. Only implementation-intention participants succeeded in reducing their disgust and fear reactions as compared to goal-intention and control participants. In Study 3, electrocortical correlates (using dense-array electroencephalography) revealed differential early visual activity in response to spider slides in ignore implementation-intention participants, as reflected in a smaller P1. Theoretical and applied implications of the present findings for emotion regulation via implementation intentions are discussed. PMID:19210061

  4. The regulator's view

    Spanish experience holds a relatively important position in the field of the decommissioning of nuclear and radioactive facilities. Nuclear facilities are subject to a system of prior authorization by the competent authorities before they come into service and to subsequent regulation and control during their operating life. Nuclear and radioactive facilities that stop operating, for technical or financial reasons or because they are compelled to, remain subject to this regulatory control system as long as the competent authorities consider that their residual radioactivity represents a potential source of radiological hazard to the individuals affected or entails an unacceptable environmental risk. The decommissioning of nuclear facilities is contemplated in Spain a further or an additional step of their life cycle in which, in principle, the whole regulatory framework in force during the previous stages - sitting, construction, commissioning, operation, etc. - remains applicable. The term decommissioning is used to delineate the final stage of the life of a definitely non-operational facility and also to introduce a new licensing regime and a new regulatory control scheme. In the regulatory context, the decommissioning of a facility is understood as a set of administrative and technical actions and processes whose purpose, once a facility has been withdrawn from service, is to release it from regulatory control and so to relieve the former licensee of its previous responsibilities relating to the facility's safety. With the increasing age of nuclear and radioactive facilities in service, and as the number of facilities reaching the end of their operating life rises, the administrative process required in order to decommissioning them safely has become a real challenge in all countries, especially in those like Spain with an old nuclear power programme. Let me first give you a quick overview of the Spanish regulatory decommissioning framework. Then I will try to

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

  7. Grandfather regulations, new source bias, and state air toxics regulations

    This paper uses plant-level data from the Census of Manufactures and the variation in toxic air pollution regulations across states to measure the effects of laws that are more stringent for new sources of pollution than for existing sources (so-called 'grandfather' regulations). Of particular interest is the resulting 'new source bias' and its effects on capital vintage and investment. Two industries are examined: commercial printing, which has a local product market; and paint manufacturing, which has a more national market. In general, there seem to be no statistically significant differences in capital vintage or investment between plants in states that grandfather new sources of pollution, plants in states that have no air toxics regulations, and plants in states that regulate both new and existing sources

    Argyriadis, K. [Germanisher Lloyd, Hamburg (Germany)


    Fatigue calculations are an essential part in certification of a wind turbine. Manufacturers have to fulfill recommendations of several different regulations throughout Europe with the result that the design has often to be altered to satisfy them. In general three national (D/GL, NL, DK), and two international (GL, IEC) regulations are in use, with the IEC standard getting more importance with wind energy deploying to more in regions with no yet clearly defined national standards (India, Spain). The Germanischer Lloyd made calculations for wind turbines they are certifying and in one case we compared the resulting damages for different regulations and classes on a 600 kW, three bladed, stall regulated wind turbine.

    This paper examines the regulation of trade in genetically modified organisms (GMOs) by the World Trade Organization (WTO). Despite rapid adoption of GMOs by a few exporters, many importers have developed relatively restrictive procedures for pre-market approval of GMOs, and are introducing mandatory labeling. While exporters have yet to seek a ruling from the WTO on these regulations, a trade dispute over GMOs is likely to occur before too long. Exporting countries will likely argue that imp...

    Moszoro, Marian


    Regulators face the difficult task of determining the sets of price and quality of government-regulated goods. While the profit-maximizing monopoly always produces less in quantity than under free competition, the level of quality produced by the monopoly is not unequivocal: it depends on its cost and demand functions. The social effect of quality change is not unequivocal either, because it depends, apart from the cost function change, on the shift and tilt change of the demand curve. The pr...

Furthermore, when the domestic firm's production technology is less efficient than that of the foreign fi...

  13. Precision Adjustable Liquid Regulator (ALR)

    Meinhold, R.; Parker, M.


    A passive mechanical regulator has been developed for the control of fuel or oxidizer flow to a 450N class bipropellant engine for use on commercial and interplanetary spacecraft. There are several potential benefits to the propulsion system, depending on mission requirements and spacecraft design. This system design enables more precise control of main engine mixture ratio and inlet pressure, and simplifies the pressurization system by transferring the function of main engine flow rate control from the pressurization/propellant tank assemblies, to a single component, the ALR. This design can also reduce the thermal control requirements on the propellant tanks, avoid costly Qualification testing of biprop engines for missions with more stringent requirements, and reduce the overall propulsion system mass and power usage. In order to realize these benefits, the ALR must meet stringent design requirements. The main advantage of this regulator over other units available in the market is that it can regulate about its nominal set point to within +/-0.85%, and change its regulation set point in flight +/-4% about that nominal point. The set point change is handled actively via a stepper motor driven actuator, which converts rotary into linear motion to affect the spring preload acting on the regulator. Once adjusted to a particular set point, the actuator remains in its final position unpowered, and the regulator passively maintains outlet pressure. The very precise outlet regulation pressure is possible due to new technology developed by Moog, Inc. which reduces typical regulator mechanical hysteresis to near zero. The ALR requirements specified an outlet pressure set point range from 225 to 255 psi, and equivalent water flow rates required were in the 0.17 lb/sec range. The regulation output pressure is maintained at +/-2 psi about the set point from a P (delta or differential pressure) of 20 to over 100 psid. Maximum upstream system pressure was specified at 320 psi

  14. Balancing Public and Private Regulation

    Martijn Scheltema


    Full Text Available Voluntary Sustainability Standards (VSS might develop into a viable alternative to public regulation. However, it turns on the (regulatory circumstances whether that holds true in practice. If public regulation on CSR topics is lacking, governments are unable to agree upon certain topics on a global level or diverging public regulation exists, VSS can be helpful to set global standards. Obviously, private standards will especially be helpful if they are commensurate with local public legislation (and e.g. treaties and/or are accepted by local governments. If one neglects this, numerous domestic structures might exist that frustrate VSS. Furthermore, governments have to remain vigilant as to whether these private regimes do not result in market disruption, consumer detriment or hamper trade. VSS might also compete with public arrangements which might limit the uptake of VSS. However, if public regulation exists VSS might be a viable alternative if compliance with not too compelling public norms by market participants is rather poor and the public policymaker is aiming to incentivize the better performing part of the market to embark on higher standards and thus only desires to regulate the less performing part of the market. However, of paramount importance is the effectiveness of VSS in order to be a viable alternative to public regulation. The effectiveness of VSS should be assessed using an integrated multi-disciplinary (comparative approach entailing legal, impact-assessment, legitimacy, governance and behavioural aspects. Only effective VSS in the aforementioned sense are a true alternative to public regulation.Beyond that, the legal perspective in connection with (the effectiveness of VSS is discussed, featuring FSC and UTZ Certified as an example. It is important from this perspective that VSS have a clear and sufficiently selective objective and sufficiently specific norms, are regularly evaluated, entail ‘conflict of law rules’ and

Very large spills are shown to cause large increases in the regulation level. In the event that an unlikely disastrous spill is realized, major regulatory reform may...

  19. Regulation of Autophagy by Kinases

    Autophagy is a process of self-degradation that maintains cellular viability during periods of metabolic stress. Although autophagy is considered a survival mechanism when faced with cellular stress, extensive autophagy can also lead to cell death. Aberrations in autophagy are associated with several diseases, including cancer. Therapeutic exploitation of this process requires a clear understanding of its regulation. Although the core molecular components involved in the execution of autophagy are well studied there is limited information on how cellular signaling pathways, particularly kinases, regulate this complex process. Protein kinases are integral to the autophagy process. Atg1, the first autophagy-related protein identified, is a serine/threonine kinase and it is regulated by another serine/threonine kinase mTOR. Emerging studies suggest the participation of many different kinases in regulating various components/steps of this catabolic process. This review focuses on the regulation of autophagy by several kinases with particular emphasis on serine/threonine protein kinases such as mTOR, AMP-activated protein kinase, Akt, mitogen-activated protein kinase (ERK, p38 and JNK) and protein kinase C that are often deregulated in cancer and are important therapeutic targets

  20. Progress toward risk informed regulation

    Rogers, K.C.


    For the last several years, the NRC, with encouragement from the industry, has been moving in the direction of risk informed regulation. This is consistent with the regulatory principle of efficiency, formally adopted by the Nuclear Regulatory Commission in 1991, which requires that regulatory activities be consistent with the degree of risk reduction they achieve. Probabilistic risk analysis has become the tool of choice for selecting the best of several alternatives. Closely related to risk informed regulation is the development of performance based rules. Such rules focus on the end result to be achieved. They do not specify the process, but instead establish the goals to be reached and how the achievement of those goals is to be judged. The inspection and enforcement activity is based on whether or not the goals have been met. The author goes on to offer comments on the history of the development of this process and its probable development in the future. He also addresses some issues which must be resolved or at least acknowledged. The success of risk informed regulation ultimately depends on having sufficiently reliable data to allow quantification of regulatory alternatives in terms of relative risk. Perhaps the area of human reliability and organizational performance has the greatest potential for improvement in reactor safety. The ability to model human performance is significantly less developed that the ability to model mechanical or electrical systems. The move toward risk informed, performance based regulation provides an unusual, perhaps unique, opportunity to establish a more rational, more effective basis for regulation.

  1. Molecular regulation of osteoclast activity.

    Bruzzaniti, Angela; Baron, Roland


    Osteoclasts are multinucleated cells derived from hematopoietic precursors that are primarily responsible for the degradation of mineralized bone during bone development, homeostasis and repair. In various skeletal disorders such as osteoporosis, hypercalcemia of malignancy, tumor metastases and Paget's disease, bone resorption by osteoclasts exceeds bone formation by osteoblasts leading to decreased bone mass, skeletal fragility and bone fracture. The overall rate of osteoclastic bone resorption is regulated either at the level of differentiation of osteoclasts from their monocytic/macrophage precursor pool or through the regulation of key functional proteins whose specific activities in the mature osteoclast control its attachment, migration and resorption. Thus, reducing osteoclast numbers and/or decreasing the bone resorbing activity of osteoclasts are two common therapeutic approaches for the treatment of hyper-resorptive skeletal diseases. In this review, several of the key functional players involved in the regulation of osteoclast activity will be discussed. PMID:16951988

  3. Developmental regulators in Aspergillus fumigatus.

    Park, Hee-Soo; Yu, Jae-Hyuk


    The filamentous fungus Aspergillus fumigatus is the most prevalent airborne fungal pathogen causing severe and usually fatal invasive aspergillosis in immunocompromised patients. This fungus produces a large number of small hydrophobic asexual spores called conidia as the primary means of reproduction, cell survival, propagation, and infectivity. The initiation, progression, and completion of asexual development (conidiation) is controlled by various regulators that govern expression of thousands of genes associated with formation of the asexual developmental structure conidiophore, and biogenesis of conidia. In this review, we summarize key regulators that directly or indirectly govern conidiation in this important pathogenic fungus. Better understanding these developmental regulators may provide insights into the improvement in controlling both beneficial and detrimental aspects of various Aspergillus species. PMID:26920882

  4. Decisions to regulate genotoxic substances

    Decisions to regulate genotoxic substances involve trade-offs between various incomparable factors such as risks to human health and other environmental risks, public perceptions, costs and uncertainties. Two different approaches towards these trade-offs are discussed. In one approach, all relevant factors are defined and trade-offs are considered using a general and very elaborate analysis. Cost-benefit analysis is an exponent of this approach. An illustration is given for the regulation of transboundary releases of radioactive materials. The other approach considers what is politically feasible for the time being and seeks a decision with much room for later corrections. Incrementalism is a philosophy in this vein. It is illustrated by reference to the regulation of transboundary air pollution. Weaknesses and strengths of the two approaches are discussed. (author)

  5. Epigenetic regulation in cardiac fibrosis

    Li-Ming; Yu; Yong; Xu


    Cardiac fibrosis represents an adoptive response in the heart exposed to various stress cues. While resolution of the fibrogenic response heralds normalization of heart function, persistent fibrogenesis is usually associated with progressive loss of heart function and eventually heart failure. Cardiac fibrosis is regulated by a myriad of factors that converge on the transcription of genes encoding extracellular matrix proteins, a process the epigenetic machinery plays a pivotal role. In this minireview, we summarize recent advances regarding the epigenetic regulation of cardiac fibrosis focusing on the role of histone and DNA modifications and non-coding RNAs.

  12. Endocannabinoid Signaling Regulates Sleep Stability

    Pava, Matthew J.; Alexandros Makriyannis; Lovinger, David M.


    The hypnogenic properties of cannabis have been recognized for centuries, but endogenous cannabinoid (endocannabinoid) regulation of vigilance states is poorly characterized. We report findings from a series of experiments in mice measuring sleep with polysomnography after various systemic pharmacological manipulations of the endocannabinoid system. Rapid, unbiased scoring of vigilance states was achieved using an automated algorithm that we devised and validated. Increasing endocannabinoid t...

    Durham, Ian T


    In this essay I develop quantum contextuality as a potential candidate for Wheeler's universal regulating principle, arguing -- \\textit{contrary} to Wheeler -- that this ultimately implies that `bit' comes from `it.' In the process I develop a formal definition of physical determinism in the languages of domain theory and category theory.

  15. Phytochrome-regulated Gene Expression

    Peter H. Quail


    Identification of all genes involved in the phytochrome (phy)-mediated responses of plants to their light environment is an important goal in providing an overall understanding of light-regulated growth and development. This article highlights and integrates the central findings of two recent comprehensive studies in Arabidopsis that have identified the genome-wide set of phy-regulated genes that respond rapidly to red-light signals upon first exposure of dark-grown seedlings, and have tested the functional relevance to normal seedling photomorphogenesis of an initial subset of these genes. The data: (a) reveal considerable complexity in the channeling of the light signals through the different phy-family members (phyA to phyE) to responsive genes; (b) identify a diversity of transcription-factor-encoding genes as major early, if not primary, targets of phy signaling, and, therefore, as potentially important regulators in the transcriptional-network hierarchy; and (c) identify auxin-related genes as the dominant class among rapidly-regulated, hormone-related genes. However, reverse-genetic functional profiling of a selected subset of these genes reveals that only a limited fraction are necessary for optimal phy-induced seedling deetiolation.

  19. Mechanisms of Hsp90 regulation

    Prodromou, Chrisostomos


    Heat shock protein 90 (Hsp90) is a molecular chaperone that is involved in the activation of disparate client proteins. This implicates Hsp90 in diverse biological processes that require a variety of co-ordinated regulatory mechanisms to control its activity. Perhaps the most important regulator is heat shock factor 1 (HSF1), which is primarily responsible for upregulating Hsp90 by binding heat shock elements (HSEs) within Hsp90 promoters. HSF1 is itself subject to a variety of regulatory processes and can directly respond to stress. HSF1 also interacts with a variety of transcriptional factors that help integrate biological signals, which in turn regulate Hsp90 appropriately. Because of the diverse clientele of Hsp90 a whole variety of co-chaperones also regulate its activity and some are directly responsible for delivery of client protein. Consequently, co-chaperones themselves, like Hsp90, are also subject to regulatory mechanisms such as post translational modification. This review, looks at the many different levels by which Hsp90 activity is ultimately regulated. PMID:27515256

  2. Regulation of the fungal secretome.

    McCotter, Sean W; Horianopoulos, Linda C; Kronstad, James W


    The ability of countless representatives of the Kingdom Fungi to adapt to and proliferate in diverse environments is facilitated by regulation of their secretomes to respond to changes in environmental conditions and to mediate interactions with other organisms. Secretome changes often fulfill common functions of nutrient acquisition, facilitation of host/symbiont interactions, cell wall modification, and optimization of the enzyme suite to adapt to new environmental resources. In this review, we expand on our recent work on signaling and the secretome in the pathogenic fungus Cryptococcus neoformans to consider a range of selected examples of regulation of fungal secretomes. These examples include the impact of carbon source and aspects of the response to plant and animal hosts. Additionally, the influence of key protein kinases (e.g., Pka1, Snf1) and transcription factors (e.g., Rim101/PacC) is highlighted to illustrate some underlying regulatory factors influencing the secretome. Although there is a wealth of information about fungal secretomes from both experimentation and genome sequence mining, there are also major gaps in our knowledge about the complete composition of fungal secretomes and mechanisms of dynamic change. For example, a more comprehensive understanding of the composition and regulation of the secretome will require consideration of the emerging roles of unconventional secretion and extracellular vesicles in delivering proteins outside the cell. Overall, changes in the secretome are well documented in diverse fungi and the underlying mechanisms are currently under investigation; however, there remain unknown steps in the regulation of secretory pathways and gaps in understanding the regulation of unconventional secretion, which warrant further research.

  7. Regulating the regulators: modulators of transcription factor activity.

    Everett, Logan; Hansen, Matthew; Hannenhalli, Sridhar


    Gene transcription is largely regulated by DNA-binding transcription factors (TFs). However, the TF activity itself is modulated via, among other things, post-translational modifications (PTMs) by specific modification enzymes in response to cellular stimuli. TF-PTMs thus serve as "molecular switchboards" that map upstream signaling events to the downstream transcriptional events. An important long-term goal is to obtain a genome-wide map of "regulatory triplets" consisting of a TF, target gene, and a modulator gene that specifically modulates the regulation of the target gene by the TF. A variety of genome-wide data sets can be exploited by computational methods to obtain a rough map of regulatory triplets, which can guide directed experiments. However, a prerequisite to developing such computational tools is a systematic catalog of known instances of regulatory triplets. We first describe PTM-Switchboard, a recent database that stores triplets of genes such that the ability of one gene (the TF) to regulate a target gene is dependent on one or more PTMs catalyzed by a third gene, the modifying enzyme. We also review current computational approaches to infer regulatory triplets from genome-wide data sets and conclude with a discussion of potential future research. PTM-Switchboard is accessible at / PMID:20827600

Epigenetics, gene regulatory and DNA modification mechanisms not involving a change to the primary sequence, have been implied in the regulation of a number of miRNA loci. Both epigenetic and miRNA signatures are broadly altered in cancer......, and are thought to play essential roles in cancer etiology and progression. Here, we aimed to identify epigenetic miRNA deregulation in bladder and oral carcinoma, and to develop a robust approach to epigenetic miRNA prediction and detection. In addition, non-canonical epigenetic functions directed by a nuclear...... miRNA were investigated. In summary, we report that the miR-200 family and miR-205 are coordinately epigenetically regulated in a variety of cell lines, tumors and normal tissues.

  10. The grammar of transcriptional regulation.

    Weingarten-Gabbay, Shira; Segal, Eran


    Eukaryotes employ combinatorial strategies to generate a variety of expression patterns from a relatively small set of regulatory DNA elements. As in any other language, deciphering the mapping between DNA and expression requires an understanding of the set of rules that govern basic principles in transcriptional regulation, the functional elements involved, and the ways in which they combine to orchestrate a transcriptional output. Here, we review the current understanding of various grammatical rules, including the effect on expression of the number of transcription factor binding sites, their location, orientation, affinity and activity; co-association with different factors; and intrinsic nucleosome organization. We review different methods that are used to study the grammar of transcription regulation, highlight gaps in current understanding, and discuss how recent technological advances may be utilized to bridge them.

  11. Endocrine regulation of circadian physiology.

    Tsang, Anthony H; Astiz, Mariana; Friedrichs, Maureen; Oster, Henrik


    Endogenous circadian clocks regulate 24-h rhythms of behavior and physiology to align with external time. The endocrine system serves as a major clock output to regulate various biological processes. Recent findings suggest that some of the rhythmic hormones can also provide feedback to the circadian system at various levels, thus contributing to maintaining the robustness of endogenous rhythmicity. This delicate balance of clock-hormone interaction is vulnerable to modern lifestyle factors such as shiftwork or high-calorie diets, altering physiological set points. In this review, we summarize the current knowledge on the communication between the circadian timing and endocrine systems, with a focus on adrenal glucocorticoids and metabolic peptide hormones. We explore the potential role of hormones as systemic feedback signals to adjust clock function and their relevance for the maintenance of physiological and metabolic circadian homeostasis. PMID:27106109

  12. Nongenomic Mechanisms of PTEN Regulation

    Jimmie E. Fata


    Full Text Available A large amount of data supports the view that PTEN is a bona fide tumor suppressor gene. However, recent evidence suggests that derailment of cellular localization and expression levels of functional nonmutated PTEN is a determining force in inducing abnormal cellular and tissue outcomes. As the cellular mechanisms that regulate normal PTEN enzymatic activity resolve, it is evident that deregulation of these mechanisms can alter cellular processes and tissue architecture and ultimately lead to oncogenic transformation. Here we discuss PTEN ubiquitination, PTEN complex formation with components of the adherens junction, PTEN nuclear localization, and microRNA regulation of PTEN as essential regulatory mechanisms that determine PTEN function independent of gene mutations and epigenetic events.

  13. Regulation by light in Fusarium.

    Avalos, Javier; Estrada, Alejandro F


    The genus Fusarium stands out as research model for pathogenesis and secondary metabolism. Light stimulates the production of some Fusarium metabolites, such as the carotenoids, and in many species it influences the production of asexual spores and sexual fruiting bodies. As found in other fungi with well-known photoresponses, the Fusarium genomes contain several genes for photoreceptors, among them a set of White Collar (WC) proteins, a cryptochrome, a photolyase, a phytochrome and two presumably photoactive opsins. The mutation of the opsin genes produced no apparent phenotypic alterations, but the loss of the only WC-1 orthologous protein eliminated the photoinduced expression of the photolyase and opsin genes. In contrast to other carotenogenic species, lack of the WC photoreceptor did not impede the light-induced accumulation of carotenoids, but produced alterations in conidiation, animal pathogenicity and nitrogen-regulated secondary metabolism. The regulation and functional role of other Fusarium photoreceptors is currently under investigation. PMID:20460165

  14. Culture, emotion regulation, and adjustment.

    Matsumoto, David; Yoo, Seung Hee; Nakagawa, Sanae


    This article reports differences across 23 countries on 2 processes of emotion regulation--reappraisal and suppression. Cultural dimensions were correlated with country means on both and the relationship between them. Cultures that emphasized the maintenance of social order--that is, those that were long-term oriented and valued embeddedness and hierarchy--tended to have higher scores on suppression, and reappraisal and suppression tended to be positively correlated. In contrast, cultures that minimized the maintenance of social order and valued individual Affective Autonomy and Egalitarianism tended to have lower scores on Suppression, and Reappraisal and Suppression tended to be negatively correlated. Moreover, country-level emotion regulation was significantly correlated with country-level indices of both positive and negative adjustment. PMID:18505309

  15. [Key regulators of skeletal myogenesis].

    Kopantseva, E E; Belyavsky, A V


    Skeletal myogenesis has been extensively studied at both morphological and molecular levels. This review considers the main stages of embryonic skeletal myogenesis and myogenic factors that trigger their initiation, focusing on specific protein interactions involved in somitic myogenesis, head myogenesis, and limb myogenesis. The second part of the review describes the role of noncoding RNAs (microRNAs and long noncoding RNAs) in myogenesis. This information is of particular interest, because regulation of cell processes by noncoding RNAs is an actively developing field of molecular biology. Knowledge of mechanisms of skeletal myogenesis is of applied significance. Various transcription factors, noncoding RNAs, and other myogenic regulators can be employed in the induction of myogenic reprogramming in stem cells and differentiated somatic cells. Current trends and strategies in the field of skeletal myogenic reprogramming are discussed in the last part of the review. PMID:27239841

  6. Lipid Regulation of Acrosome Exocytosis.

    Cohen, Roy; Mukai, Chinatsu; Travis, Alexander J


    Lipids are critical regulators of mammalian sperm function, first helping prevent premature acrosome exocytosis, then enabling sperm to become competent to fertilize at the right place/time through the process of capacitation, and ultimately triggering acrosome exocytosis. Yet because they do not fit neatly into the "DNA--RNA-protein" synthetic pathway, they are understudied and poorly understood. Here, we focus on three lipids or lipid classes-cholesterol, phospholipids, and the ganglioside G(M1)--in context of the modern paradigm of acrosome exocytosis. We describe how these various- species are precisely segregated into membrane macrodomains and microdomains, simultaneously preventing premature exocytosis while acting as foci for organizing regulatory and effector molecules that will enable exocytosis. Although the mechanisms responsible for these domains are poorly defined, there is substantial evidence for their composition and functions. We present diverse ways that lipids and lipid modifications regulate capacitation and acrosome exocytosis, describing in more detail how removal of cholesterol plays a master regulatory role in enabling exocytosis through at least two complementary pathways. First, cholesterol efflux leads to proteolytic activation of phospholipase B, which cleaves both phospholipid tails. The resultant changes in membrane curvature provide a mechanism for the point fusions now known to occur far before a sperm physically interacts with the zona pellucida. Cholesterol efflux also enables G(M1) to regulate the voltage-dependent cation channel, Ca(V)2.3, triggering focal calcium transients required for acrosome exocytosis in response to subsequent whole-cell calcium rises. We close with a model integrating functions for lipids in regulating acrosome exocytosis. PMID:27194352

    Lee, Samuel; Persson, Petra


    We study sex trafficking in a marriage market model of prostitution. When traffickers can coerce women to sell sex, trafficked prostitutes constitute a non-zero share of supply in any unregulated market for sex. We ask if regulation can eradicate trafficking and restore the equilibrium that would arise in an unregulated market without traffickers. While all existing approaches – criminalization of prostitutes (“the traditional model”), licensed prostitution (“the Dutch model”), and criminaliz...

  8. Tbx1 regulates brain vascularization.

    Cioffi, Sara; Martucciello, Stefania; Fulcoli, Filomena Gabriella; Bilio, Marchesa; Ferrentino, Rosa; Nusco, Edoardo; Illingworth, Elizabeth


    The transcription factor TBX1 is the major gene involved in 22q11.2 deletion syndrome (22q11.2DS). Using mouse models of these diseases, we have previously shown that TBX1 activates VEGFR3 in endothelial cells (EC), and that this interaction is critical for the development of the lymphatic vasculature. In this study, we show that TBX1 regulates brain angiogenesis. Using loss-of-function genetics and molecular approaches, we show that TBX1 regulates the VEGFR3 and DLL4 genes in brain ECs. In mice, loss of TBX1 causes global brain vascular defects, comprising brain vessel hyperplasia, enhanced angiogenic sprouting and vessel network disorganization. This phenotype is recapitulated in EC-specific Tbx1 conditional mutants and in an EC-only 3-dimensional cell culture system (matrigel), indicating that the brain vascular phenotype is cell autonomous. Furthermore, EC-specific conditional Tbx1 mutants have poorly perfused brain vessels and brain hypoxia, indicating that the expanded vascular network is functionally impaired. In EC-matrigel cultures, a Notch1 agonist is able to partially rescue microtubule hyperbranching induced by TBX1 knockdown. Thus, we have identified a novel transcriptional regulator of angiogenesis that exerts its effect in brain by negatively regulating angiogenesis through the DLL4/Notch1-VEGFR3 regulatory axis. Given the similarity of the phenotypic consequences of TBX1 mutation in humans and mice, this unexpected role of TBX1 in murine brain vascularization should stimulate clinicians to search for brain microvascular anomalies in 22q11.2DS patients and to evaluate whether some of the anatomical and functional brain anomalies in patients may have a microvascular origin.

  9. Regulation of Lipolysis in Adipocytes

    Duncan, Robin E.; Ahmadian, Maryam; Jaworski, Kathy; Sarkadi-Nagy, Eszter; Sul, Hei Sook


    Lipolysis of white adipose tissue triacylglycerol stores results in the liberation of glycerol and nonesterified fatty acids that are released into the vasculature for use by other organs as energy substrates. In response to changes in nutritional state, lipolysis rates are precisely regulated through hormonal and biochemical signals. These signals modulate the activity of lipolytic enzymes and accessory proteins, allowing for maximal responsiveness of adipose tissue to changes in energy requ...

  16. Regulation Mechanisms of Stomatal Oscillation

    Hui-Min YANG; Jian-Hua ZHANG; Xiao-Yan ZHANG


    Stomata function as the gates between the plant and the atmospheric environment. Stomatal movement, including stomatal opening and closing, controls CO2 absorption as the raw material for photosynthesis and water loss through transpiration. How to reduce water loss and maintain enough CO2 absorption has been an interesting research topic for some time. Simple stomatal opening may elevate CO2 absorption,but, in the meantime, promote the water loss, whereas simple closing of stomatal pores may reduce both water loss and CO2 absorption, resulting in impairment of plant photosynthesis. Both processes are not economical to the plant. As a special rhythmic stomatal movement that usually occurs at smaller stomatal apertures, stomatal oscillation can keep CO2 absorption at a sufficient level and reduce water loss at the same time, suggesting a potential improvement in water use efficiency. Stomatal oscillation is usually found after a sudden change in one environmental factor in relatively constant environments. Many environmental stimuli can induce stomatal oscillation. It appears that, at the physiological level, feedback controls are involved in stomatal oscillation. At the cellular level, possibly two different patterns exist: (i) a quicker responsive pattern; and (ii) a slower response. Both involve water potential changes and water channel regulation, but the mechanisms of regulation of the two patterns are different. Some evidence suggests that the regulation of water channels may play a vital and primary role in stomatal oscillation. The present review summarizes studies on stomatal oscillation and concludes with some discussion regarding the mechanisms of regulation of stomatal oscillation.

    It has been established that regulation of chromatin structure through post-translational modification of histone proteins, primarily histone H3 phosphorylation and acetylation, is an important early step in the induction of synaptic plasticity and formation of long-term memory. In this study, we investigated the contribution of another histone modification, histone methylation, to memory formation in the adult hippocampus. We found that tri-methylation of histone H3 at lysine 4 (H3K4), an ac...

  19. International comparison of taxi regulations

    Sytze Rienstra, Peter Bakker, Johan Visser


    IntroductionIn 2014, research was conducted to evaluate the changes made in 2011 to the taxi regulations contained in the national Passenger Transport Act 2000. During the course of this research, Uber’s introduction in the taxi market emerged as an increasingly important focal point. In particular, UberPOP – a service connecting customers to private drivers (operating their own vehicles) via a smartphone app – generated much debate. It is in this context that the Directorate General Accessib...

  20. Hate crimes and normative regulation

    Kovačević Milica


    Full Text Available This paper is primarily devoted to issues related to the normative regulation of hate crimes, with special reference to the regulations of the Republic of Serbia, which are indirectly related to this matter. This kind of crimes are characterized by prejudices that perpetrators have towards injured parties, as members of certain, mostly, minority groups, due to which many hate crimes could be also called crimes of prejudice. In comparative law there are two different basic directions when it comes to regulating hate crimes: separation of hate crimes in a separate category on the one hand, and punishment of perpetrators of criminal acts with the detriment of minority groups through the usual charges of a given criminal justice system, on the other. The author finds that, regardless of the formal response forms, real life suggests that hate crimes can be essentially suppressed only by promoting values such as equality, respect for diversity and tolerance, and by continuous education of public about the danger of hate crimes.

  1. Endocannabinoid Regulation of Neuroendocrine Systems.

    Tasker, Jeffrey G; Chen, Chun; Fisher, Marc O; Fu, Xin; Rainville, Jennifer R; Weiss, Grant L


    The hypothalamus is a part of the brain that is critical for sustaining life through its homeostatic control and integrative regulation of the autonomic nervous system and neuroendocrine systems. Neuroendocrine function in mammals is mediated mainly through the control of pituitary hormone secretion by diverse neuroendocrine cell groups in the hypothalamus. Cannabinoid receptors are expressed throughout the hypothalamus, and endocannabinoids have been found to exert pronounced regulatory effects on neuroendocrine function via modulation of the outputs of several neuroendocrine systems. Here, we review the physiological regulation of neuroendocrine function by endocannabinoids, focusing on the role of endocannabinoids in the neuroendocrine regulation of the stress response, food intake, fluid homeostasis, and reproductive function. Cannabis sativa (marijuana) has a long history of recreational and/or medicinal use dating back to ancient times. It was used as an analgesic, anesthetic, and antianxiety herb as early as 2600 B.C. The hedonic, anxiolytic, and mood-elevating properties of cannabis have also been cited in ancient records from different cultures. However, it was not until 1964 that the psychoactive constituent of cannabis, Δ(9)-tetrahydrocannabinol, was isolated and its chemical structure determined (Gaoni & Mechoulam, 1964). PMID:26638767

  2. The mother as hidden regulator

    Annie Panzer


    Full Text Available A human baby is born with a decidedly immature brain, and is absolutely dependent on an intense relationship with its mother (or primary caregiver for brain maturation. In the short term, maternal regulation contributes to a more joyful baby, while in the long term it leads to the internalisation and development of self-regulatory capabilities. The ability to regulate one’s own emotional states is based on the development of right orbitofrontal dominance of dual limbic circuits, i.e. the excitatory sympathetic ventral tegmental circuit, and the inhibitory parasympathetic lateral tegmental circuit. Thus the child will be able to calm down after nigh overwhelming emotions by activating the parasympathetic system, but also to bounce back after setbacks by activating the sympathetic system. The mother influences the parcellation of the two limbic systems and thus the permanent excitation-inhibition autonomic balance of its prefrontal regulatory system. Repeated unregulated emotional states in the practicing period from 12-18 months pave the way for various psychological and psychiatric disorders in adulthood. It is worrisome that many children pass through this critical time in nursery schools, where a shortage of adult staff may lead to the scenario where a child’s emotions are repeatedly not modulated, with dire consequences for the internalisation of its future self-regulating capabilities.

    Full Text Available Obesity in young people is now realised as a worldwide crisis of epidemic proportion. The aetiology of this disease suggests a disruption in regulation of energy at the population level, leading to a positive energy balance and excess adiposity. The relative contribution of food intake and physical inactivity remains to be elucidated. Treatment interventions have aimed to create a deficit in energy balance through manipulation of physical activity, behavioural components or, to a lesser extent, dietary modification. Whether such intervention is maintained in the long-term is as yet unclear, however it seems a combination of therapies is optimal. Mindful of a mismatch between energy intake and expenditure, recent work has begun to examine the acute relationship between physical activity and food intake in children. Initial findings suggest a short-term delay in compensation through energy intake for exercise- induced energy expenditure. The overarching study of energy regulation in children and adolescents is clearly multifaceted in nature and variables to be assessed or manipulated require careful consideration. The collection of paediatric physical activity, energy expenditure and food intake data is a time-consuming process, fraught with potential sources of error. Investigators should consider the validity and reliability of these and other issues, alongside the logistics of any proposed study. Despite these areas of concern, recent advances in the field should provide exciting opportunities for future research in paediatric energy regulation on a variety of levels

  4. Musical affect regulation in infancy.

    Trehub, Sandra E; Ghazban, Niusha; Corbeil, Mariève


    Adolescents and adults commonly use music for various forms of affect regulation, including relaxation, revitalization, distraction, and elicitation of pleasant memories. Mothers throughout the world also sing to their infants, with affect regulation as the principal goal. To date, the study of maternal singing has focused largely on its acoustic features and its consequences for infant attention. We describe recent laboratory research that explores the consequences of singing for infant affect regulation. Such work reveals that listening to recordings of play songs can maintain 6- to 9-month-old infants in a relatively contented or neutral state considerably longer than recordings of infant-directed or adult-directed speech. When 10-month-old infants fuss or cry and are highly aroused, mothers' multimodal singing is more effective than maternal speech at inducing recovery from such distress. Moreover, play songs are more effective than lullabies at reducing arousal in Western infants. We explore the implications of these findings along with possible practical applications. PMID:25773634

  5. Negative regulators of cell proliferation

    Johnson, T. C.; Spooner, B. S. (Principal Investigator)


    Cell proliferation is governed by the influence of both mitogens and inhibitors. Although cell contact has long been thought to play a fundamental role in cell cycling regulation, and negative regulators have long been suspected to exist, their isolation and purification has been complicated by a variety of technical difficulties. Nevertheless, over recent years an ever-expanding list of putative negative regulators have emerged. In many cases, their biological inhibitory activities are consistent with density-dependent growth inhibition. Most likely their interactions with mitogenic agents, at an intracellular level, are responsible for either mitotic arrest or continued cell cycling. A review of naturally occurring cell growth inhibitors is presented with an emphasis on those factors shown to be residents of the cell surface membrane. Particular attention is focused on a cell surface sialoglycopeptide, isolated from intact bovine cerebral cortex cells, which has been shown to inhibit the proliferation of an unusually wide range of target cells. The glycopeptide arrest cells obtained from diverse species, both fibroblasts and epithelial cells, and a broad variety of transformed cells. Signal transduction events and a limited spectrum of cells that are refractory to the sialoglycopeptide have provided insight into the molecular events mediated by this cell surface inhibitor.

  6. Detecting aquaporin function and regulation

    Madeira, Ana; Moura, Teresa; Soveral, Graça


    Water is the major component of cells and tissues throughout all forms of life. Fluxes of water and solutes through cell membranes and epithelia are essential for osmoregulation and energy homeostasis. Aquaporins are membrane channels expressed in almost every organism and involved in the bidirectional transfer of water and small solutes across cell membranes. Aquaporins have important biological roles and have been implicated in several pathophysiological conditions suggesting a great translational potential in aquaporin-based diagnostic and therapeutics. Detecting aquaporin function is critical for assessing regulation and screening for new activity modulators that can prompt the development of efficient medicines. Appropriate methods for functional analysis comprising suitable cell models and techniques to accurately evaluate water and solute membrane permeability are essential to validate aquaporin function and assess short-term regulation. The present review describes established assays commonly used to assess aquaporin function in cells and tissues, as well as the experimental biophysical strategies required to reveal functional regulation and identify modulators, the first step for aquaporin drug discovery.

  7. NRC - regulator of nuclear safety



    The U.S. Nuclear Regulatory Commission (NRC) was formed in 1975 to regulate the various commercial and institutional uses of nuclear energy, including nuclear power plants. The agency succeeded the Atomic Energy Commission, which previously had responsibility for both developing and regulating nuclear activities. Federal research and development work for all energy sources, as well as nuclear weapons production, is now conducted by the U.S. Department of Energy. Under its responsibility to protect public health and safety, the NRC has three principal regulatory functions: (1) establish standards and regulations, (2) issue licenses for nuclear facilities and users of nuclear materials, and (3) inspect facilities and users of nuclear materials to ensure compliance with the requirements. These regulatory functions relate to both nuclear power plants and to other uses of nuclear materials - like nuclear medicine programs at hospitals, academic activities at educational institutions, research work, and such industrial applications as gauges and testing equipment. The NRC places a high priority on keeping the public informed of its work. The agency recognizes the interest of citizens in what it does through such activities as maintaining public document rooms across the country and holding public hearings, public meetings in local areas, and discussions with individuals and organizations.

  8. Optical regulation of cell chain

    Liu, Xiaoshuai; Huang, Jianbin; Zhang, Yao; Li, Baojun


    Formation of cell chains is a straightforward and efficient method to study the cell interaction. By regulating the contact sequence and interaction distance, the influence of different extracellular cues on the cell interaction can be investigated. However, it faces great challenges in stable retaining and precise regulation of cell chain, especially in cell culture with relatively low cell concentration. Here we demonstrated an optical method to realize the precise regulation of cell chain, including removing or adding a single cell, adjusting interaction distance, and changing cell contact sequence. After injecting a 980-nm wavelength laser beam into a tapered optical fiber probe (FP), a cell chain of Escherichia colis (E. colis) is formed under the optical gradient force. By manipulating another FP close to the cell chain, a targeted E. coli cell can be trapped by the FP and removed from the chain. Further, the targeted cell can be added back to the chain at different positions to change the cell contact sequence. The experiments were interpreted by numerical simulations and the impact of cell sizes and shapes on this method was analyzed.

  10. Deregulation, a challenge for regulators

    Deregulation and competitiveness in the electricity market invites the plant owner/operator to reduce operating cost with a potential reduction in maintenance, degradation of investment in safety, reduction of operating staff and a downgrading in research and development. On the other side, deregulation and competitiveness brings the social and industrial benefit of reducing the electricity cost. Regulatory organisations have to watch that the safety level of the plant does not go beyond the established level, while recognising the benefits of the new situation; therefore they have the moral responsibility of regulating nuclear energy effectively and efficiently and in eliminating unnecessary regulatory burdens. Regulation has evolved with time and in accordance with the knowledge gained from research and the analysis of operating experience. The knowledge gained has made it possible to follow the path of other modern advanced technologies, where risk is quantified and the system approved when the risk becomes lower than an accepted level. The regulatory use of this advanced tool is being now developed by the most advanced regulatory organisations, under the name of risk informed regulation, where the reference level is the expected frequency of core damage. Deregulation and competitiveness will not change the basis of the already well established procedure to verify compliance. Nevertheless, the contents of Safety Analysis Reports and other regulatory documents, such as Technical Specifications for Operation, offer room for improvement in the sense of being more to the roots of the matter and becoming more efficient tools in the verification process. The contents of these documents have been evolving along the time and they have become unnecessary voluminous and rather burdensome. Much work has been done to improve the efficiency of regulatory inspections by concentrating on basic aspects. As a partial application of the already mentioned risk-informed regulation
