    2015-01-01

    This paper offers a framework for regulating internalities. Using a simple economic model, we provide four principles for designing and evaluating behaviorally-motivated policy. We then outline rules for determining which contexts reliably reflect true preferences and discuss empirical strategies for measuring internalities. As a case study, we focus on energy efficiency policy, including Corporate Average Fuel Economy (CAFE) standards and appliance and lighting energy efficiency standards.

    Ketamine is an anesthetic commonly used in low-income countries and has recently been shown to be effective for treatment-resistant depression. However, the illicit manufacturing, trafficking, and nonmedical use of ketamine are increasing globally, and its illicit use poses major public health challenges in many countries. To review the nonmedical use of ketamine in selected countries and its regulatory control. We conducted a review of literature identified from searches of the China National Knowledge Infrastructure (CNKI) (1979-2016) and PubMed databases, supplemented by additional references identified by the authors. Special attention was given to the regulation of ketamine. Illicit manufacturing, trafficking, and use of ketamine appear to have begun on a large scale in several Asian nations, and it has subsequently spread to other regions. Regulations governing availability of ketamine vary across countries, but there is a clear trend toward tighter regulations. As nonmedical use of ketamine and its harmful consequences have worsened globally, stricter controls are necessary. Appropriate regulation of ketamine is important for international efforts to control ketamine's cross-border trafficking and its nonmedical use.

    These lecture notes contain an overview of basic problems of the International Radio Regulations. Access to the existing information infrastructure, and to that of the future Information Society, depends critically on radio, especially in poor, remote and sparsely populated regions with under-developed telecommunication infrastructure. How the spectrum of radio frequencies is regulated has profound impact on the society, its security, prosperity, and culture. The radio regulations represent a very important framework for an adequate use of radio and should be known by all of those working in the field.

    We empirically investigate the responsiveness of international trade to the stringency of environmental regulation. Stringent environmental regulation may impair the export competitiveness of 'dirty' domestic industries, and as a result, 'pollution havens' emerge in countries where environmental regulation is 'over-lax.' We examine the impact of pollution abatement and control costs on net exports in order to grasp this phenomenon. Theoretically, our analysis is related to a general equilibrium model of trade and pollution nesting the pollution haven motive for trade with the factor endowment motive. We analyze data on two-digit ISIC manufacturing industries during the period 1977-1992 in Germany, the Netherlands and the US, and show that trade patterns in 'dirty' commodities are jointly determined by relative factor endowments and environmental stringency differentials.

    A review of the development of the IAEA Radiological Protection standards is given. The basic features of the latest revision recently adopted by the governing bodies of the sponsoring organizations, i.e. IAEA, WHO, ILO, NEA/OECD are discussed and some of the features of the future Agency programme for its implementation will be outlined. In particular, attention will be given to development of the basic principles for setting release limits of radioactive materials into the environment. An important aspect of this is when the release of radioactive materials into the environment crosses international boundaries. The Agency is best suited to try to reach a consensus on the minimum monetary value for the unit collective dose. (orig./RW)

    The existence of a traceable relationship between national regulatory standards and international recommendations is important especially when the national regulations have to be justified and explained to the public and their representatives. Guidance on various types of radiological levels in environmental media related to public exposure has been provided by the relevant international organizations, constituting a basis for the development of national regulations. However, international standards need to be clear and based on solid technical criteria. In their preparation, consideration should be given to the implications for different countries, and the differences that exist between them, for example, in social, economic and climatic aspects.

    Self-regulation by business is increasingly common internationally, but the effective implementation of international rules often continues to be seen as something that only states can carry out. We argue that more exclusively private forms of effective implementation can be constructed in self......-regulation. Drawing on research in private international law, public policy implementation and self-regulation, we identify four distinct implementation sequences: monitoring, compliance, adjudication, and sanctioning. These sequences are sometimes constituted in response to deliberate integrated plans, but also come...... together in a decentralized manner. Many international business actors devise ways to carry out the sequences in order to implement rules that are important for them, reflecting a functional logic of implementation that is creative and pragmatic, and together constitute an important stage in the policy...

  18. Account of internal friction when estimating recoverable creep strain

    International Nuclear Information System (INIS)

    Demidov, A.S.

    1986-01-01

    It is supposed that a difference of empirical and calculated data on the creep strain recovery for Kh18N10T steel under conditions of cyclic variations in stress is specified by the effect of internal friction. In the accepted model of creep β-flow is considered to be reversible and γ-flow- irreversible. Absorptivity is determined as a ratio of the difference between the expended work and work of strain recovery forces to the work expended in cycle. A notion of the equivalent stress acting in the period of the creep strain recovery is introduced. Results of the calculation according to the empirical formula where absorptivity was introduced into are compared with empirical data obtained for Kh18N10T steel at 750 deg C

  20. An International Model for Antibiotics Regulation.

    Science.gov (United States)

    Aguirre, Emilie

    We face a global antibiotics resistance crisis. Antibiotic drugs are rapidly losing their effectiveness, potentially propelling us toward a post-antibiotic world. The largest use of antibiotics in the world is in food-producing animals. Food producers administer these drugs in routine, low doses—the types of doses that are incidentally the most conducive to breeding antibiotic resistance. In general, individual countries have been too slow to act in regulating misuse and overuse of antibiotics in foodproducing animals. This problem will only worsen with the significant projected growth in meat consumption and production expected in emerging economies in the near future. Although individual countries regulating antibiotics can have important effects, one country alone cannot insulate itself entirely from the effects of antibiotic resistance, nor can one country solve the crisis for itself or for the world. The global nature of the food system and the urgency of the problem require immediate global solutions. Adapting a democratic experimentalist approach at the international level can help achieve this goal. Using an international democratic experimentalist framework in conjunction with the World Organization for Animal Health (OIE) would provide for increased systematized data collection and lead to heightened, scientifically informed OIE standards, enforceable by the World Trade Organization (WTO), which could have a significant impact on the reduction of subtherapeutic use of antibiotics internationally. International democratic experimentalism addresses the global intricacy, time sensitivity, context- and culture-specificity, and knowledgeintensiveness of this problem. By encouraging more countries to experiment to solve this problem, the democratic experimentalist model would help develop a larger database of solutions to enable more meaningful cross-country comparisons across a wider range of contexts. This approach maintains democratic governance and

  3. Comparison of international food allergen labeling regulations.

    Gendel, Steven M

    2012-07-01

    Food allergy is a significant public health issue worldwide. Regulatory risk management strategies for allergic consumers have focused on providing information about the presence of food allergens through label declarations. A number of countries and regulatory bodies have recognized the importance of providing this information by enacting laws, regulations or standards for food allergen labeling of "priority allergens". However, different governments and organizations have taken different approaches to identifying these "priority allergens" and to designing labeling declaration regulatory frameworks. The increasing volume of the international food trade suggests that there would be value in supporting sensitive consumers by harmonizing (to the extent possible) these regulatory frameworks. As a first step toward this goal, an inventory of allergen labeling regulations was assembled and analyzed to identify commonalities, differences, and future needs. Published by Elsevier Inc.

  4. OUTSOURCING ETHICAL DILEMMAS: REGULATING INTERNATIONAL SURROGACY ARRANGEMENTS.

    Fenton-Glynn, Claire

    2016-01-01

    This article argues that the English legislative regime is ineffective in regulating international surrogacy, particularly with regard to commercial payments. It suggests that if English law views surrogacy as exploitative, we have a responsibility to protect women both in England and abroad, and the only way to do so effectively is to create a domestic system of regulation that caters adequately for the demand in this country. This requires a system of authorisation for surrogacy before it is undertaken; ex-post facto examinations of agreements completed in other jurisdictions, after the child is already living with the commissioning parents, cannot be seen as an acceptable compromise, as authorisation will inevitably be granted in the child's best interests. © The Author 2016.

  7. Internal-strain effect on the valence band of strained silicon and its correlation with the bond angles

    2014-02-14

    By means of the first-principles density-functional theory, we investigate the effect of relative atom displacement in the crystal unit cell, namely, internal strain on the valence-band dispersion of strained silicon, and find close correlation of this effect with variation in the specific bond angles due to internal strain. We consider the [111] ([110]) band dispersion for (111) ((110)) biaxial tensility and [111] ([110]) uniaxial compression, because remarkably small values of hole effective mass m* can be obtained in this dispersion. Under the practical condition of no normal stress, biaxial tensility (uniaxial compression) involves additional normal compression (tensility) and internal strain. With an increase in the internal-strain parameter, the energy separation between the highest and second-highest valence bands becomes strikingly larger, and the highest band with conspicuously small m* extends remarkably down to a lower energy region, until it intersects or becomes admixed with the second band. This is closely correlated with the change in the specific bond angles, and this change can reasonably explain the above enlargement of the band separation.

  9. Internal strains after recovery of hardness in tempered martensitic steels for fusion reactors

    Science.gov (United States)

    Brunelli, L.; Gondi, P.; Montanari, R.; Coppola, R.

    1991-03-01

    After tempering, with recovery of hardness, MANET steels present internal strains; these residual strains increase with quenching rate prior to tempering, and they remain after prolonged tempering times. On account of their persistence, after thermal treatments which lead to low dislocation and sub-boundary densities, the possibility has been considered that the high swelling resistance of MANET is connected with these centres of strain, probably connected with the formation, in ferrite, of Cr-enriched and contiguous Cr-depleted zones which may act as sinks for interstitials. Comparative observations on the internal strain behaviour of cold worked 316L stainless steel appear consistent with this possibility.

  10. Internal residual strain mapping in carburized chrome molybdenum steel after quenching by neutron strain scanning

    2011-01-01

    A hollow circular cylinder specimen with an annular U-notch of chrome molybdenum steel with 0.20 mass% C (SCM420) was carburized in carrier gas and quenched in oil bath. In order to determine the case depth, the specimen was cut off and carbon content and Vickers hardness gradients were measured experimentally near the carburized surface. The residual strain mapping in the interior of carburized cylinder was conducted nondestructively by neutron strain scanning. In this study, the neutron diffraction from Fe-211 plane was used for strain scanning. The neutron wavelength was tuned to 0.1654nm so that diffraction angle became about 90deg. Radial, hoop and axial residual strains were measured by scanning diffracting volume along the axial direction of cylinder specimen. Each residual strain was calculated from lattice spacing change. Unstressed lattice spacing was determined experimentally using reference coupon specimens that were cut from the interior of same carburized cylinder. As a result, the diffraction peak width at half height, FWHM, near the carburized surface was about 3.7 times wider than that of coupon specimens. On the other hand, the most peak widths in the interior equaled to that of coupon specimens. Peak width broadened slightly as the diffracting volume approached the carburized case layer. From the center to the quarter of cylinder specimen, the hoop and axial strains were tensile, and the radial one was compressive in the interior. From the quarter to the edge of the cylinder specimen, the hoop tensile strain increased, radial and axial strains changed to tensile and compressive, respectively. Therefore, the interior of the cylinder specimen was found to be deformed elastically to balance the existence of compressive residual stresses in the carburized case layer. (author)

    Price regulation is an instrument between two diverging aims: The demand for low resource prices motivated by the principle of equal distribution in our day, and the desire for economical management of resources as a responsibility we have to future generations. The present publication investigates how price regulation influences intertemporal supply of resources. For the assumed cases constant resource price, constant admissible increase in resource price, expected release of resource price and deregulation of a price held constant for a period of time mathematical models are developmed.

    The development of a twinned microstructure in hexagonal close-packed rolled magnesium compressed in the in-plane direction has been monitored in situ with neutron diffraction. The continuous conversion of the parent to daughter microstructure is tracked through the variation of diffraction peak intensities corresponding to each. Approximately 80% of the parent microstructure twins by 8% compression. Elastic lattice strain measurements indicate that the stress in the newly formed twins (daughters) is relaxed relative to the stress field in the surrounding matrix. However, since the daughters are in a plastically 'hard' deformation orientation, they quickly accumulate elastic strain as surrounding grains deform plastically. Polycrystal modeling of the deformation process provides insight about the crystallographic deformation mechanism involved.

    The paper is aimed to study the dynamic accumulation regulation of curcumin (Cur), demethoxycurcumin (DMC) and bisdemethoxyeurcumin (BDMC) in three strains of Curcuma longa, and provide scientific references for formalized cultivation, timely harvesting, quality control and breeding cultivation of C. longa. The accumulation regulation of the three curcumin derivatives was basically the same in rhizome of three strains. The relative contents decreased along with plant development growing, while the accumulation per hectare increased with plant development growing. The accumulation of curcuminoids per hectare could be taken as the assessment standard for the best harvest time of C. longa. A3 was the best strain in terms of Cur and BDMC content.

    The presence of residual stress in engineering components can effect their mechanical properties and structural integrity. Neutron diffraction in the only technique that can make nondestructive measurements in the interior of components. By recording the change in crystalline lattice spacings, elastic strains can be measured for individual lattice reflections. Using a pulsed neutron source, all lattice reflections are recorded in each measurement, which allows for easy examination of heterogeneous materials such as metal matrix composites. Measurements made at the Manuel Lujan Jr. Neutron Scattering Center (LANSCE) demonstrate the potential at pulsed sources for in-situ stress measurements at ambient and elevated temperatures

    2013-01-01

    International Regulations for the transport of radioactive materials have been published by International Atomic Energy Agency (IAEA) since 1961. These Regulations have been widely adopted into national Regulations. Also adopted into different modal Regulations such as International Air Transport Association (IATA) and International Martime Organization (IMO). These Regulations provide standards for insuring a high level of safety of general public, transport workers, property and environment against radiation, contamination, criticality hazard and thermal effects associated with the transport of radioactive wastes and materials. Several reviews conducted in consultation with Member States (MS) and concerned international organizations, resulted in comprehensive revisions till now. Radioactive materials are generally transported by specialized transport companies and experts. Shippers and carriers have designed their transport operations to comply with these international Regulations. About 20 million consignments of radioactive materials take place around the world each year. These materials were used in different fields such as medicine, industry, agriculture, research, consumer product and electric power generation. After September 11,2001, the IAEA and MS have worked together to develop a new guidance document concerning the security in the transport of radioactive materials. IAEA have initiated activities to assist MS in addressing the need for transport security in a comprehensive manner. The security guidance and measures were mentioned and discussed. The transport security becomes more developed and integrated into national Regulations of many countries beside the safety Regulations. IAEA and other International organizations are working with MS to implement transport security programs such as guidance, training, security assessments and upgrade assistance in these fields.

  3. TTP specifically regulates the internalization of the transferrin receptor

    DEFF Research Database (Denmark)

    Tosoni, Daniela; Puri, Claudia; Confalonieri, Stefano

    2005-01-01

    Different plasma membrane receptors are internalized through saturable/noncompetitive pathways, suggesting cargo-specific regulation. Here, we report that TTP (SH3BP4), a SH3-containing protein, specifically regulates the internalization of the transferrin receptor (TfR). TTP interacts...... with endocytic proteins, including clathrin, dynamin, and the TfR, and localizes selectively to TfR-containing coated-pits (CCP) and -vesicles (CCV). Overexpression of TTP specifically inhibits TfR internalization, and causes the formation of morphologically aberrant CCP, which are probably fission impaired....... This effect is mediated by the SH3 of TTP, which can bind to dynamin, and it is rescued by overexpression of dynamin. Functional ablation of TTP causes a reduction in TfR internalization, and reduced cargo loading and size of TfR-CCV. Tyrosine phosphorylation of either TTP or dynamin prevents...

    In 2005, the International Health Regulations were adopted at the 58th World Health Assembly; in June 2007, they were entered into force for most countries. In 2012, the world is approaching a major 5-year milestone in the global commitment to ensure national capacities to identify, investigate, assess, and respond to public health events. In the past 5 years, existing programs have been boosted and some new activities relating to International Health Regulations provisions have been successfully established. The lessons and experience of the past 5 years need to be drawn upon to provide improved direction for the future.

  5. Coordinated Evolution of Transcriptional and Post-Transcriptional Regulation for Mitochondrial Functions in Yeast Strains.

    Directory of Open Access Journals (Sweden)

    Xuepeng Sun

    Full Text Available Evolution of gene regulation has been proposed to play an important role in environmental adaptation. Exploring mechanisms underlying coordinated evolutionary changes at various levels of gene regulation could shed new light on how organism adapt in nature. In this study, we focused on regulatory differences between a laboratory Saccharomyces cerevisiae strain BY4742 and a pathogenic S. cerevisiae strain, YJM789. The two strains diverge in many features, including growth rate, morphology, high temperature tolerance, and pathogenicity. Our RNA-Seq and ribosomal footprint profiling data showed that gene expression differences are pervasive, and genes functioning in mitochondria are mostly divergent between the two strains at both transcriptional and translational levels. Combining functional genomics data from other yeast strains, we further demonstrated that significant divergence of expression for genes functioning in the electron transport chain (ETC was likely caused by differential expression of a transcriptional factor, HAP4, and that post-transcriptional regulation mediated by an RNA-binding protein, PUF3, likely led to expression divergence for genes involved in mitochondrial translation. We also explored mito-nuclear interactions via mitochondrial DNA replacement between strains. Although the two mitochondrial genomes harbor substantial sequence divergence, neither growth nor gene expression were affected by mitochondrial DNA replacement in both fermentative and respiratory growth media, indicating compatible mitochondrial and nuclear genomes between these two strains in the tested conditions. Collectively, we used mitochondrial functions as an example to demonstrate for the first time that evolution at both transcriptional and post-transcriptional levels could lead to coordinated regulatory changes underlying strain specific functional variations.

    The abundance and significant contribution to global primary production of the marine cyanobacterium Prochlorococcus have made it one of the main models in marine ecology. Several conditions known to cause strong effects on the regulation of N-related enzymes in other cyanobacteria lacked such effect in Prochlorococcus. Prochlorococcus sp. strain MIT9313 is one of the most early-branching strains among the members of this genus. In order to further understand the C/N control system in this cyanobacterium, we studied the effect of the absence of three key elements in the ocean, namely N, P and Fe, as well as the effect of inhibitors of the N assimilation or photosynthesis on the N metabolism of this strain. Furthermore, we focused our work in the effect of ageing, as the age of cultures has clear effects on the regulation of some enzymes in Prochlorococcus. To reach this goal, expression of the main three regulators involved in N assimilation in cyanobacteria, namely ntcA, glnB and pipX, as well as that of icd (encoding for isocitrate dehydrogenase) were analysed. Our results show that the control of the main proteins involved in the C/N balance in strain MIT9313 differs from other model Prochlorococcus strains. © FEMS 2017. All rights reserved.

  11. International Safety Regulation and Standards for Space Travel and Commerce

    Science.gov (United States)

    Pelton, J. N.; Jakhu, R.

    The evolution of air travel has led to the adoption of the 1944 Chicago Convention that created the International Civil Aviation Organization (ICAO), headquartered in Montreal, Canada, and the propagation of aviation safety standards. Today, ICAO standardizes and harmonizes commercial air safety worldwide. Space travel and space safety are still at an early stage of development, and the adoption of international space safety standards and regulation still remains largely at the national level. This paper explores the international treaties and conventions that govern space travel, applications and exploration today and analyzes current efforts to create space safety standards and regulations at the national, regional and global level. Recent efforts to create a commercial space travel industry and to license commercial space ports are foreseen as means to hasten a space safety regulatory process.

  12. Efficiency analysis of energy networks: An international survey of regulators

    2009-01-01

    Incentive regulation for networks has been an important part of the reform agenda in a number of countries. As part of this regulatory process, incentives are put in place to improve the cost efficiency of network companies by rewarding good performance relative to a pre-defined benchmark. The techniques used to establish benchmarks are central to the efficiency improvements that are ultimately achieved. Much experience has been gained internationally in the application of benchmarking techniques and we now have a solid understanding of the main indicators of best practice. What we are lacking is a more complete understanding of the factors that influence choice of methods by regulators. In this paper, we present the results of an international survey of energy regulators in 40 countries conducted electronically between June and October 2008. Regulators from European, Australasian and Latin American countries are represented in the survey. Our results show that benchmarking techniques are now widespread in the regulation of gas and electricity networks. Best practice, however, is limited to a small number of regulators. We conclude by summarising existing trends and offering some recommendations on overcoming barriers to best practice efficiency analysis.

  13. Clinical research involving minors in international and serbian regulations.

    2013-07-01

    Participation in clinical trials can be useful for the health of a person, in who it is conducted, but it does not have to be - it can even be harmful. Therefore, primary motive to accept such risk is humanity and human wish to contribute to the progress of medicine; this is expressed by personal consent. The consent, however, can be an expression of personal humanity, and for this, it is not logical that someone can give consent on behalf of someone else, as it is done by a legally authorized representative on behalf of a minor. Therefore, authors raise 3 questions: What are the reasons to consider representative's consent acceptable? How should a model of regulations look like in order to provide the most complete possible protection to a minor? Is actual regulation of minors' position within international and Serbian law, analyzed here by authors for their specific solutions, acceptable? Representative's consent is acceptable only for therapeutic research, because these can bring benefits to everyone's health, including a minor in which those are conducted - this is an acceptable (secondary) motive of participation in the research. Expression of humanity on other's behalf, typical for non-therapeutic research, is not acceptable; this makes ban of minors' participation in non-therapeutic research more appropriate regulation model. International regulations are not in accordance to results presented in the paper for allowing participation of minors both in therapeutic and non-therapeutic research. Serbian regulation is closer to the most acceptable regulation model.

    Full Text Available Background: In 1930's first whole cell pertussis vaccines became available to the public heralding a dramatic success in overcoming the global burden of the disease. To date only a handful of B. pertussis strains have been used by international/local pertussis vaccine manufacturers. Inevitable well-documented genetic changes in the world population of this pathogen have prompted serious questions on suitability of traditional vaccine strains protect human against currently circulating wild isolates of Bordetella pertussis. Objective: Analyzing the genetic diversity within the most frequently-used vaccine strains of B. pertussis in the world Methods: A recently developed multi locus variable number of tandem repeats analysis (MLVA genotyping system along with a bioinforamtic piece of analysis was conducted on 11 strain / substrains of B137, B203 (10536, C393, Cs, E476, Tohama I, J445 (134, B202 and J446 (509 plus 2 sub-strains of 134 and 509 that are used at Razi institute for preparation of pertussis vaccine. In this study have used 6 individual loci of VNTR1, VNTR3a, VNTR3b, VNTR4, VNTR5 and VNTR6. Findings: Six distinct genotypes were recognized among the examined strains by comparing our data with the Dutch MLVA databank. These were all new and not reported before in the database. Conclusion: This observation reiterates on necessity for detection of predominant native strains to include in vaccine preparations suitable for different countries.

    The strain effect of REBa_2Cu_3O_y (REBCO: RE = Y, Gd, Sm)-coated conductors (CCs) on critical current (I_c) is one of the most fundamental factors for superconducting coil applications. In this study, we aim to clarify the effect of artificial pinning center shapes on the strain effect in BHO-doped GdBCO CCs. To achieve this, we fabricated a Pure-GdBCO CC, a BHO nanorod-doped GdBCO CC and a multilayered-GdBCO (ML-GdBCO) CC, and carried out bending tests. As the result, the strain dependence of I_c for each CC showed an upward convex and the peak strain of the BHO-doped GdBCO CC shifts towards the compressive strain independent of the BHO shapes. In addition, the strain sensitivity of I_c in the GdBCO CCs including BHO becomes smaller. To clarify the difference between the strain sensitivity of I_c and the peak strain among the CCs, we evaluated the residual strain and the slopes of the internal lattice strains against the applied tensile strain (β). From this measurement, the residual strains for the Pure-GdBCO CC and the ML-GdBCO CC were almost the same. In addition, there was no change in the β value between the Pure-GdBCO and ML-GdBCO CCs. These results suggest that the changes in peak strain and strain sensitivity were not related to the internal lattice strain. (author)

    The study of religion is severely handicapped by a lack of adequate cross-national data. Despite the prominence of religion in international events and recent theoretical models pointing to the consequences of regulating religion, cross-national research on religion has been lacking. We strive to fill this void by developing measurement models and indexes for government regulation, government favoritism, and social regulation of religion. The indexes rely on data from an extensive coding of the 2003 International Religious Freedom Report for 196 countries and territories. Using a series of tests to evaluate the new data and indexes, we find that the measures developed are highly reliable and valid. The three indexes will allow researchers and others to measure the government’s subsidy and regulation of religion as well as the restrictions placed on religion by social and cultural forces beyond the state.

  18. INTERNAL REGULATIONS OF INTERNATIONAL COMPANIES OPERATING IN POLAND AND TRADITIONAL FAMILY MODEL

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Most of the big companies have the internal regulations about human resources management. The bylaws in question are usually created in the reality of a particular legal system. When a company expands abroad, it starts operating in a different legal system than its own. As a result, the bylaws are not always compatible neither with laws nor the legal culture of the state of a new market. The paper touches upon the problem of the cohesion of internal regulations of some of the international companies operating in Poland with the traditional family model established in Polish law analyzing three areas such as: supporting parenting, family business, and preference for non-heterosexual persons. The conclusions are that some of the internal regulations are not coherent with Polish law, and some of the bylaws regarding, e.g., daycare or flexible working hours, can be adapted to Polish legal system. It (unclear what “it” is referring to would benefit traditional model of the family. The paper contains also the excursus about some legis-lative phenomenon regarding the reception of state law regulations issues by private companies and pos-tulates that the Polish legislator shall be open to new ideas in this matter and search for the well-tried regulations.

    Shock absorption is the most important function of the human heel pad. However, changes in heel pad elasticity, as seen in e.g. long-distance runners, diabetes patients, and victims of Falanga torture are affecting this function, often in a painful manner. Assessment of heel pad elasticity is usually based on one or a few strain measurements obtained by an external load-deformation system. The aim of this study was to develop a technique for quantitative measurements of heel pad elastic modulus based on several internal strain measures from within the heel pad by use of ultrasound images. Nine heel phantoms were manufactured featuring a combination of three heel pad stiffnesses and three heel pad thicknesses to model the normal human variation. Each phantom was tested in an indentation system comprising a 7MHz linear array ultrasound transducer, working as the indentor, and a connected load cell. Load-compression data and ultrasound B-mode images were simultaneously acquired in 19 compression steps of 0.1mm each. The internal tissue displacement was for each step calculated by a phase-based cross-correlation technique and internal strain maps were derived from these displacement maps. Elastic moduli were found from the resulting stress-strain curves. The elastic moduli made it possible to distinguish eight of nine phantoms from each other according to the manufactured stiffness and showed very little dependence of the thickness. Mean elastic moduli for the three soft, the three medium, and the three hard phantoms were 89kPa, 153kPa, and 168kPa, respectively. The combination of ultrasound images and force measurements provided an effective way of assessing the elastic properties of the heel pad due to the internal strain estimation.

  1. The international regulation of Informal Value Transfer Systems

    Directory of Open Access Journals (Sweden)

    Anand Ajay Shah

    2007-12-01

    Full Text Available After the 11th September 2001 attacks on the United States international attention quickly focused on the sources and methods of terrorist financing. Among the methods terrorists and other criminal actors use to transfer funds are Informal Value Transfer Systems (IVTS which operate either outside the formal financial sector, or through use of the formal financial sector, but without leaving a full record of the transaction. Though the vast majority of funds moved through IVTS are the earnings of migrant workers and immigrant communities, the lack of uniform worldwide regulation of IVTS provides ample opportunity for abuse and misuse. The international community primarily responded to IVTS concerns through the Financial Action Task Force on Money Laundering, which issued a series of recommendations and best practices for states in regulating IVTS operations. While these recommendations are a secure beginning to regulation of IVTS operating within ethnic communities, they fail to address the more modern forms of IVTS that have come about in the post-Cold War globalised world. Comprehensive recommendations governing all types of IVTS, as well as concerted international cooperation and coordination are necessary to address this global phenomenon.

  2. Regulation of thrombomodulin expression and release in human aortic endothelial cells by cyclic strain.

    Fiona A Martin

    Full Text Available Thrombomodulin (TM, an integral membrane glycoprotein expressed on the lumenal surface of vascular endothelial cells, promotes anti-coagulant and anti-inflammatory properties. Release of functional TM from the endothelium surface into plasma has also been reported. Much is still unknown however about how endothelial TM is regulated by physiologic hemodynamic forces (and particularly cyclic strain intrinsic to endothelial-mediated vascular homeostasis.This study employed human aortic endothelial cells (HAECs to investigate the effects of equibiaxial cyclic strain (7.5%, 60 cycles/min, 24 hrs, and to a lesser extent, laminar shear stress (10 dynes/cm2, 24 hrs, on TM expression and release. Time-, dose- and frequency-dependency studies were performed.Our initial studies demonstrated that cyclic strain strongly downregulated TM expression in a p38- and receptor tyrosine kinase-dependent manner. This was in contrast to the upregulatory effect of shear stress. Moreover, both forces significantly upregulated TM release over a 48 hr period. With continuing focus on the cyclic strain-induced TM release, we noted both dose (0-7.5% and frequency (0.5-2.0 Hz dependency, with no attenuation of strain-induced TM release observed following inhibition of MAP kinases (p38, ERK-1/2, receptor tyrosine kinase, or eNOS. The concerted impact of cyclic strain and inflammatory mediators on TM release from HAECs was also investigated. In this respect, both TNFα (100 ng/ml and ox-LDL (10-50 µg/ml appeared to potentiate strain-induced TM release. Finally, inhibition of neither MMPs (GM6001 nor rhomboids (3,4-dichloroisocoumarin had any effect on strain-induced TM release. However, significantly elevated levels (2.1 fold of TM were observed in isolated microparticle fractions following 7.5% strain for 24 hrs.A preliminary in vitro investigation into the effects of cyclic strain on TM in HAECs is presented. Physiologic cyclic strain was observed to downregulate TM

  5. Transcriptional Regulation and the Diversification of Metabolism in Wine Yeast Strains

    Rossouw, Debra; Jacobson, Dan; Bauer, Florian F.

    2012-01-01

    Transcription factors and their binding sites have been proposed as primary targets of evolutionary adaptation because changes to single transcription factors can lead to far-reaching changes in gene expression patterns. Nevertheless, there is very little concrete evidence for such evolutionary changes. Industrial wine yeast strains, of the species Saccharomyces cerevisiae, are a geno- and phenotypically diverse group of organisms that have adapted to the ecological niches of industrial winemaking environments and have been selected to produce specific styles of wine. Variation in transcriptional regulation among wine yeast strains may be responsible for many of the observed differences and specific adaptations to different fermentative conditions in the context of commercial winemaking. We analyzed gene expression profiles of wine yeast strains to assess the impact of transcription factor expression on metabolic networks. The data provide new insights into the molecular basis of variations in gene expression in industrial strains and their consequent effects on metabolic networks important to wine fermentation. We show that the metabolic phenotype of a strain can be shifted in a relatively predictable manner by changing expression levels of individual transcription factors, opening opportunities to modify transcription networks to achieve desirable outcomes.

    Optically pure D-: amino acids, like D-: hydroxyphenylglycine, are used in the semi-synthetic production of pharmaceuticals. They are synthesized industrially via the biocatalytic hydrolysis of p-hydroxyphenylhydantoin using enzymes derived from Agrobacterium tumefaciens strains. The reaction proceeds via a three-step pathway: (a) the ring-opening cleavage of the hydantoin ring by a D-: hydantoinase (encoded by hyuH), (b) conversion of the resultant D-: N-carbamylamino acid to the corresponding amino acid by a D-: N-carbamoylase (encoded by hyuC), and (c) chemical or enzymatic racemization of the un-reacted hydantoin substrate. While the structure and biochemical properties of these enzymes are well understood, little is known about their origin, their function, and their regulation in the native host. We investigated the mechanisms involved in the regulation of expression of the hydantoinase and N-carbamoylase enzyme activity in A. tumefaciens strain RU-AE01. We present evidence for a complex regulatory network that responds to the growth status of the cells, the presence of inducer, and nitrogen catabolite repression. Deletion analysis and site-directed mutagenesis were used to identify regulatory elements involved in transcriptional regulation of hyuH and hyuC expression. Finally, a comparison between the hyu gene clusters in several Agrobacterium strains provides insight into the function of D-: selective hydantoin-hydrolyzing enzyme systems in Agrobacterium species.

    As a novel tool for quantitative 3D internal deformation measurement throughout the interior of a material or tissue, digital volume correlation (DVC) has increasingly gained attention and application in the fields of experimental mechanics, material research and biomedical engineering. However, the practical implementation of DVC involves important challenges such as implementation complexity, calculation accuracy and computational efficiency. In this paper, a least-squares framework is presented for 3D internal displacement and strain field measurement using DVC. The proposed DVC combines a practical linear-intensity-change model with an easy-to-implement iterative least-squares (ILS) algorithm to retrieve 3D internal displacement vector field with sub-voxel accuracy. Because the linear-intensity-change model is capable of accounting for both the possible intensity changes and the relative geometric transform of the target subvolume, the presented DVC thus provides the highest sub-voxel registration accuracy and widest applicability. Furthermore, as the ILS algorithm uses only first-order spatial derivatives of the deformed volumetric image, the developed DVC thus significantly reduces computational complexity. To further extract 3D strain distributions from the 3D discrete displacement vectors obtained by the ILS algorithm, the presented DVC employs a pointwise least-squares algorithm to estimate the strain components for each measurement point. Computer-simulated volume images with controlled displacements are employed to investigate the performance of the proposed DVC method in terms of mean bias error and standard deviation error. Results reveal that the present technique is capable of providing accurate measurements in an easy-to-implement manner, and can be applied to practical 3D internal displacement and strain calculation.

    Full Text Available Objective to review the current situation in production and distribution of unmanned aerial vehicles further ndash UAVs in developed countries as well as the legal regulation issues. Methods abstractlogic summarizing and observation comparative analysis. Results The analysis of international trade in UAVs revealed the leading countries dominating the market Israel the USA and Canada. The leading importers are India UK and France. China and Russian Federation are important producers but are just marginally involved in international trade having rather protectionist trade policies. The characters of national regulatory frameworks vary significantly from country to country while the Czech Republic belongs to the rather liberal group of EU members. Scientific novelty So far the journal publications in regard of UAVs have addressed uniquely technical issues and economic issues have been unattended. This paper clarifies the terminology mess analyses trade policy issues trade and production statistics and regulatory concerns linked to this steeply growing segment that is subject to doubleuse items regulations. Practical value Given a lack of relevant publications focused on international trade in UAVs in particular the paper provides a complex overview of current state of play in terms of this promising yet very controversial subject.

  10. Regulation of international roaming data services within the EU

    DEFF Research Database (Denmark)

    Falch, Morten; Tadayoni, Reza

    2014-01-01

    Europe has been the first region to intervene on the market for international roaming services. The first regulation was introduced in 2007 and has since then been revised several times. The latest revision took place in the summer 2012. This paper discusses the new legislation in view of recent...... market developments from a technological, economic and a regulatory perspective. The paper concludes that roaming charges have been reduced substantially since the introduction of prices caps, but still the charges are far above a level, which can be justified by the production costs. A number...... of alternatives to tradition roaming have been developed, but so far their impact on competition have been limited, and it will take some years before the present regulation can be lifted....

  11. New International Initiatives on Enhancement of Biosafety and Biosecurity Regulations for Laboratories Handling Infectious Agents

    Before we entered the era of antibiotics, development of antiseptics rules and reliable water purification systems the infectious pathogens had played a major role in morbidity and mortality of global human population. The advances in revealing the nature of dangerous infections and studying their causative agents during the recent years have led not only to big progress in their control but also to the study of their potential as weapons. During the last fifty years, several attempts have been made to use them for criminal or terrorist purposes that demonstrated that even primitively organized terrorist attacks may lead to quite significant consequences. The October 2001 events showed that bioterrorism attacks may be prepared, probably, as a result of theft of the pathogen from a lab. All this led to the revision and radical improvement of current national rules and international recommendations in the field of handling, storage and transportation of infectious agents. As a result, during the past two years these rules have been significantly revised by both the World Health Organization and some countries. However, their harmonization of is still far from what is desired. Therefore, biosafety professionals in some countries, including those of the European Union, are establishing professional biosafety associations. In addition, new initiatives are being proposed to develop internationally harmonized biosecurity rules to govern dangerous pathogens handling and storage. The most important of them are as follows: 1. Development, under the auspices of WHO, of new recommendations concerning a set of requirements to provide physical security of both biological agents and laboratories involved in research on extremely hazardous infections; 2. Enhacement, under the auspices of WHO, of current international recommendations on inventory procedures and regulations, inventory monitoring, and transportation of specimens and strains of extremely hazardous infections; 3

  12. Sulfate as a pivotal factor in regulation of Serratia sp. strain S2B pigment biosynthesis.

    Rastegari, Banafsheh; Karbalaei-Heidari, Hamid Reza

    2016-10-01

    In the present work, we investigated the prodiginine family as secondary metabolite members. Bacterial strain S2B, with the ability to produce red pigment, was isolated from the Sarcheshmeh copper mine in Iran. 16S rDNA gene sequencing revealed that the strain was placed in the Serratia genus. Pigment production was optimized using low-cost culture medium and the effects of various physicochemical factors were studied via statistical approaches. Purification of the produced pigment by silica gel column chromatography showed a strong red pigment fraction and a weaker orange band. Mass spectrometry, FT-IR spectroscopy and (1)H NMR analysis revealed that the red pigment was prodigiosin and the orange band was a prodigiosin-like analog, with molecular weights of 323 and 317 Da, respectively. Genotoxicity and cytotoxicity studies confirmed their membership in the prodiginine family. Analysis of the production pattern of the pigments in the presence of different concentrations of ammonium salts revealed the role of sulfate as an important factor in regulation of the pigment biosynthesis pathway. Overall, the data showed that regulation of the pigment biosynthesis pathway in Serratia sp. strain S2B was affected by inorganic micronutrients, particularly the sulfate ions.

    It should be explained more to the outside modestly the Fukushima nuclear accident would be a man-made complex disaster, which might be reluctant to do but not be neglected. Utmost efforts to change inward-looking attitude and reform safety culture should be done so as to prevent superficial reflection of the Fukushima nuclear accident. Since all nuclear regulatory functions ('3S': safety, security, safeguards) were integrated in Nuclear Regulation Authority (NRA), NRA and secretariat of NRA became more responsible for international response, and strengthening of organization system and human resources development would be an urgent necessity. This article described present stage of NRA focusing on international dimension including personal views. Overseas strong concern over the Fukushima nuclear accident and international communications were reviewed. The Fukushima nuclear accident started from natural disaster and enlarged as a man-made complex disaster with many human factors (mainly inaction, wilful negligence) overlapping and safety culture flawed. Examples of overseas and Japanese action plan to learn and absorb lessons from the Fukushima accident were introduced. NRA's started activities on inviting IAEA's IRRS and OPPAS as soon as ready, strengthening nuclear security measures, safeguards to prevent nuclear proliferation, bilateral cooperation and international advisors were also presented.

  19. Global health security and the International Health Regulations

    Directory of Open Access Journals (Sweden)

    Oliva Otavio

    2010-12-01

    Full Text Available Abstract Global nuclear proliferation, bioterrorism, and emerging infections have challenged national capacities to achieve and maintain global security. Over the last century, emerging infectious disease threats resulted in the development of the preliminary versions of the International Health Regulations (IHR of the World Health Organization (WHO. The current HR(2005 contain major differences compared to earlier versions, including: substantial shifts from containment at the border to containment at the source of the event; shifts from a rather small disease list (smallpox, plague, cholera, and yellow fever required to be reported, to all public health threats; and shifts from preset measures to tailored responses with more flexibility to deal with the local situations on the ground. The new IHR(2005 call for accountability. They also call for strengthened national capacity for surveillance and control; prevention, alert, and response to international public health emergencies beyond the traditional short list of required reporting; global partnership and collaboration; and human rights, obligations, accountability, and procedures of monitoring. Under these evolved regulations, as well as other measures, such as the Revolving Fund for vaccine procurement of the Pan American Health Organization (PAHO, global health security could be maintained in the response to urban yellow fever in Paraguay in 2008 and the influenza (H1N1 pandemic of 2009-2010.

    International Nuclear Information System (INIS)

    Davis, M.W.

    1997-01-01

    Naturally Occurring Radioactive Material (NORM) was first recognized as a potential problem as long ago as 1904 in the oil fields of Canada. NORM later became an issue in the North Sea oil and gas production facilities in the early 1980's and became more widely recognized in the United States in 1986 during a routine well workover in the state of Mississippi. NORM contamination of oil and gas industry production equipment has since been identified world wide. The United States, including Alaska and the Gulf of Mexico region, the North Sea region, the United Kingdom, Canada, Australia and several Middle Eastern countries have all reported NORM contamination. The purpose of this paper is to discuss some of the international regulations or guidelines that have been promulgated concerning NORM in the oil and gas industry. Additionally, the impact of these regulations or guidelines on non-oil and gas industries will also be discussed. A comparison of these regulations or guidelines to those generally found in the United States shall be drawn

    International Nuclear Information System (INIS)

    Goodzeit, C.L.; Anerella, M.D.; Ganetis, G.L.

    1988-01-01

    An improved method has been developed for the measurement of internal forces in superconducting accelerator magnets, in particular the compressive stresses in coils and the end restraint forces on the coils. The transducers have been designed to provide improved sensitivity to purely mechanical strain by using bending mode deflections for sensing the applied loads. Strain gauge resistance measurements are made with a new system that eliminates sources of errors due to spurious resistance changes in interconnecting wiring and solder joints. The design of the transducers and their measurement system is presented along with a discussion of the method of compensation for thermal and magnetic effects, methods of calibration with typical calibration data, and measured effect in actual magnets of the thermal stress changes from cooldown and the Lorentz forces during magnet excitation. 13 figs., 1 tab

    Shock absorption is the most important function of the human heel pad. However, changes in heel pad elasticity, as seen in e.g. long-distance runners, diabetes patients, and victims of Falanga torture are affecting this function, often in a painful manner. Assessment of heel pad elasticity...... is usually based on one or a few strain measurements obtained by an external load-deformation system. The aim of this study was to develop a technique for quantitative measurements of heel pad elastic modulus based on several internal strain measures from within the heel pad by use of ultrasound images. Nine...... heel phantoms were manufactured featuring a combination of three heel pad stiffnesses and three heel pad thicknesses to model the normal human variation. Each phantom was tested in an indentation system comprising a 7MHz linear array ultrasound transducer, working as the indentor, and a connected load...

  4. Transcription and Regulation of the Bidirectional Hydrogenase in the Cyanobacterium Nostoc sp. Strain PCC 7120▿

    2007-01-01

    The filamentous, heterocystous cyanobacterium Nostoc sp. strain PCC 7120 (Anabaena sp. strain PCC 7120) possesses an uptake hydrogenase and a bidirectional enzyme, the latter being capable of catalyzing both H2 production and evolution. The completely sequenced genome of Nostoc sp. strain PCC 7120 reveals that the five structural genes encoding the bidirectional hydrogenase (hoxEFUYH) are separated in two clusters at a distance of approximately 8.8 kb. The transcription of the hox genes was examined under nitrogen-fixing conditions, and the results demonstrate that the cluster containing hoxE and hoxF can be transcribed as one polycistronic unit together with the open reading frame alr0750. The second cluster, containing hoxU, hoxY, and hoxH, is transcribed together with alr0763 and alr0765, located between the hox genes. Moreover, alr0760 and alr0761 form an additional larger operon. Nevertheless, Northern blot hybridizations revealed a rather complex transcription pattern in which the different hox genes are expressed differently. Transcriptional start points (TSPs) were identified 66 and 57 bp upstream from the start codon of alr0750 and hoxU, respectively. The transcriptions of the two clusters containing the hox genes are both induced under anaerobic conditions concomitantly with the induction of a higher level of hydrogenase activity. An additional TSP, within the annotated alr0760, 244 bp downstream from the suggested translation start codon, was identified. Electrophoretic mobility shift assays with purified LexA from Nostoc sp. strain PCC 7120 demonstrated specific interactions between the transcriptional regulator and both hox promoter regions. However, when LexA from Synechocystis sp. strain PCC 6803 was used, the purified protein interacted only with the promoter region of the alr0750-hoxE-hoxF operon. A search of the whole Nostoc sp. strain PCC 7120 genome demonstrated the presence of 216 putative LexA binding sites in total, including recA and rec

    1990-07-01

    There is an increase in international laser safety requirements as part of the emphasis on world-wide standardization of products and regulations. In particular the documents which will evolve from the 1992 consolidation efforts of the European Community (EC) will impact both laser manufacturers and users. This paper provides a discussion of the current status of the various laser radiation standards. NORTH AMERICAN REQUIREMENTS United States Requirements on manufacturers from the Food and Drug Administration (FDA) have been in effect since 1975. The Center for Devices and Radiological Health (CDRH) within that agency ensures that these mandatory requirements [1] are satisfied. The CDRH regulations include the division of products into classes depending on their potential for hazard criteria for power measurement and requirements for product features labels and manuals and records and reports. Manufacturers must test products and certify that they comply with the CDRH requirements. User requirements are found in a standard published by the American National Standards Institute (ANSI) and in requirements from several individual states. Specific ANSI standards have also been published for fiber communications systems [34] and for lasers in medical applications [35]. Please note that the Appendix includes additional information on the standards discussed in this paper including sources for obtaining the documents. Canada In the past Canada has had requirements for two specified product categories (bar code scanners and educational lasers) [26 These will be replaced

  6. Shaping the norms that regulate international commerce of embryos.

    Gard, Julie A; Stringfellow, David A

    2014-01-01

    As various embryo technologies in livestock were developed and evolved to a state of usefulness over the past 40 years, scientists with a specific interest in infectious diseases sought to determine the epidemiologic consequences of movement, especially international movement, of increasing numbers of embryos. Many of the foundational studies in this area were reported in Theriogenology, beginning in the 1970s and especially throughout the 1980s and 1990s. Unquestionably, Theriogenology has been a widely used venue for dissemination of basic information on this subject, which ultimately led to the development of the now universally accepted techniques for certification of embryo health. Today it is well-recognized that movement in commerce of embryos, especially in vivo-derived embryos, is a very low-risk method for exchange of animal germ plasm. This paper chronicles the evolution of strategies for health certification of embryos. An overview is provided of the calculated efforts of practitioners, scientists, and regulators to organize, forge necessary partnerships, stimulate needed research, provide purposeful analysis of the results, and, through these processes, guarantee the universal acceptance of efficient protocols for certifying the health of embryos intended for movement in international commerce.

  7. Altered Regulation of Escherichia coli Biotin Biosynthesis in BirA Superrepressor Mutant Strains

    Science.gov (United States)

    Chakravartty, Vandana

    2012-01-01

    Transcription of the Escherichia coli biotin (bio) operon is directly regulated by the biotin protein ligase BirA, the enzyme that covalently attaches biotin to its cognate acceptor proteins. Binding of BirA to the bio operator requires dimerization of the protein, which is triggered by BirA-catalyzed synthesis of biotinoyl-adenylate (biotinoyl-5′-AMP), the obligatory intermediate of the ligation reaction. Although several aspects of this regulatory system are well understood, no BirA superrepressor mutant strains had been isolated. Such superrepressor BirA proteins would repress the biotin operon transcription in vivo at biotin concentrations well below those needed for repression by wild-type BirA. We isolated mutant strains having this phenotype by a combined selection-screening approach and resolved multiple mutations to give several birA superrepressor alleles, each having a single mutation, all of which showed repression dominant over that of the wild-type allele. All of these mutant strains repressed bio operon transcription in vivo at biotin concentrations that gave derepression of the wild-type strain and retained sufficient ligation activity for growth when overexpressed. All of the strains except that encoding G154D BirA showed derepression of bio operon transcription upon overproduction of a biotin-accepting protein. In BirA, G154D was a lethal mutation in single copy, and the purified protein was unable to transfer biotin from enzyme-bound biotinoyl-adenylate either to the natural acceptor protein or to a biotin-accepting peptide sequence. Consistent with the transcriptional repression data, each of the purified mutant proteins showed increased affinity for the biotin operator DNA in electrophoretic mobility shift assays. Surprisingly, although most of the mutations were located in the catalytic domain, all of those tested, except G154D BirA, had normal ligase activity. Most of the mutations that gave superrepressor phenotypes altered residues

    1996-02-05

    An average internal strain in the electrodeposited Zn-Ni alloy films was in-situ measured using the resistance wire type strain gauge setup on the reverse side of the copper substrate. The Ni content of the Zn-Ni alloy coatings utilized for the steel frame of automobiles and for the plastic coated steel sheets is around at 15% and the dominant structure is the {gamma}-phase. Such Zn-Ni alloy coatings are favorable for the protection of steel against corrosion. The internal stress in these deposits is always compressive during electroplating. However, upon turning off the current, the internal stress sharply changes from compressive to tensile. The tensile stress seems to simultaneously result in many cracks on the surface of the deposits. In this study, a resistance wire type strain gauge meter was used for successive measurement of the internal strain in the deposits during electroplating and solid-state stripping voltammetry was applied for the anodic dissolution of the deposits. And the effects concerning the partial electroleaching of Zn from the deposits on the internal strain in the deposits under periodic reverse plating. 15 refs., 8 figs., 3 tabs.

    The internal strain parameter of GaAs has been measured by observing the stress-dependence of the integrated intensity of the weak 006 reflection, with the compressive stress along the [1anti 10] axis. An energy-dispersive technique was employed so that the reflection could be obtained at a photon energy close to the minimum in the structure factor, thereby approaching closely the strictly-forbidden condition that applies at any energy in the diamond structure. A value anti A=-0.138±0.005, equivalent to a bond-bending parameter ζ=0.55=0.02, has been found. This is in good agreement with recent theoretical calculations and indirect determinations related to the bandstructure of GaAs. (orig.)

    2016-01-01

    The temperature of dynamic strain aging (DSA) regime in P91 steel is between 523 K and 773 K. The activation energy (Q) for onset of DSA is 73 kJ/mol, while that for finale of DSA is 202 kJ/mol. Two main Internal friction (IF) speaks were observed, Snoek and SKK with the activation energy of 67.9 kJ/mol and 121 kJ/mol, respectively. IF shows that activation energy of 73 kJ/mol is equal to that of C atom body diffusion in α-Fe, and 202 kJ/mol is equal to binding energy between C atoms and moving dislocations. These results confirm that the mechanism of DSA can be explained by the diffusion of C atoms and pinning between C and moving dislocation. These investigations indicate that DSA in P91 steel is resulted from C atom diffusion, instead of Cr or Mo atoms.

    Directory of Open Access Journals (Sweden)

    Sritharan M

    2004-01-01

    Full Text Available BACKGROUND: Iron deficiency has been shown to induce the expression of siderophores and their receptors, the iron-regulated membrane proteins in a number of bacterial systems. In this study, the response of Leptospira biflexa serovar Patoc strain Patoc I to conditions of iron deprivation was assessed and the expression of siderophores and iron-regulated proteins is reported. MATERIALS AND METHODS: Two methods were used for establishing conditions of iron deprivation. One method consisted of addition of the iron chelators ethylenediamine-N, N′-diacetic acid (EDDA and ethylenediamine di-o-hydroxyphenylacetic acid (EDDHPA and the second method involved the addition of iron at 0.02 µg Fe/mL. Alternatively, iron sufficient conditions were achieved by omitting the chelators in the former method and adding 4 µg Fe/mL of the medium in the latter protocol. Triton X-114 extraction of the cells was done to isolate the proteins in the outer membrane (detergent phase, periplasmic space (aqueous phase and the protoplasmic cylinder (cell pellet. The proteins were subjected to SDS-PAGE for analysis. RESULTS: In the presence of the iron-chelators, four iron-regulated proteins (IRPs of apparent molecular masses of 82, 64, 60 and 33 kDa were expressed. The 82-kDa protein was seen only in the aqueous phase, while the other three proteins were seen in both the aqueous and detergent fractions. These proteins were not identified in organisms grown in the absence of the iron chelators. The 64, 60 and the 33 kDa proteins were also demonstrated in organisms grown in media with 0.02 µg Fe/mL. In addition, a 24 kDa protein was found to be down-regulated at this concentration of iron as compared to the high level of expression in organisms grown with 4 µg Fe/mL. The blue CAS agar plates with top agar containing 0.02µg Fe/mL showed a colour change to orange-red. CONCLUSION: The expression of siderophores and iron-regulated proteins under conditions of iron deprivation

    Phage T4 internal protein I(IPI), a small (ca, 10,000 MW), basic protein injected into the host with the phage DNA, is not required for infection of most hosts, but mutants defective in IPI are restricted by at least one naturally occurring strain of Escherichia coli, CT 596 (CT). Phages lacking IPI (IPI - ) appear to inject their DNA and bind it to the membrane of CT cells as well as wild-type phage T4 does, but shutoff of host protein synthesis, initiation of T4 protein synthesis, and cell killing are abnormal in the IPI - mutant infected CT host. The injection of IPI appears to be important in allowing T4 DNA to carry out early steps involved in takeover of this host. Restriction of IPI - phage growth by CT cells appears to be due, at least in part, to a defective prophage it harbors which renders the host resistant to successful infection by phage T4 which lack IPI or rII functions. Bacteria cured of this prophage can be infected by mutants defective in these functions. The resistance of CT cells to other coliphages, and the question of T-even phage internal protein diversity are discussed. (U.S.)

    Full Text Available Through the hereby study we set ourselves on an analysis over the internal control and the ways of implementation of it. The final purpose of our research is represented by the characteristics of the internal control system in the context of current accountancy regulations. The accomplishment of such goal has forced us to research the current literature in the area and also the legal regulations over internal control. Of course, the accomplishment of such a research was possible only after a pertinent analysis over the opinions expressed in specialty literature regarding this area. Our research wants to be with a theoretical and applicative character. It is based on analysing the internal control system, the methodology of internal control and the steps of internal control. We express our belief that the implementation of the internal control in a very exact manner comes as an aid to the company management and lead to the accomplishment of managerial objectives and policies. In what it regards the result of our research there can be drawn the following conclusions: from the legal regulations (OMFP nr. 3055/2009, there is no clear conclusion over the procedures and policies of implementation of internal control applicable to an economical entity; also there are not presented in a detailed way the types (forms of internal control, being presented in the legal regulations only a classification of them after the time in which they are exercised (before, during or after the finishing of the operations; also in the legal regulations there is developed a certain way of internal control, represented by the financial and accounting internal control, as if the other forms of internal control do not exist; in what regards the components of internal control, these are presented in another way, but similar to already known models of internal control (Coso and Coco; also in the legal regulations there are presented the general objectives of internal control

    2001-01-01

    We examine the optimal environmental regulation of three Norwegian power projects: energy conservation, a natural gas fired CCGT and a new hydro project. All projects reduce emissions elsewhere in the Nordic region, and the environmental costs of these emissions are not, in general, fully reflected in market prices. We develop a theory of second best optimal regulation for this case. The optimal regulation is found to deviate substantially from a purely domestic regulation. For instance, we find it optimal to grant a substantial credit to energy conservation. The credit is sensitive to the value of reduced CO 2 emissions and whether the current Norwegian end user tax should be interpreted as an environmental or a fiscal tax

  11. Conditional reverse tet-transactivator mouse strains for the efficient induction of TRE-regulated transgenes in mice.

    Directory of Open Access Journals (Sweden)

    Lukas E Dow

    Full Text Available Tetracycline or doxycycline (dox-regulated control of genetic elements allows inducible, reversible and tissue specific regulation of gene expression in mice. This approach provides a means to investigate protein function in specific cell lineages and at defined periods of development and disease. Efficient and stable regulation of cDNAs or non-coding elements (e.g. shRNAs downstream of the tetracycline-regulated element (TRE requires the robust expression of a tet-transactivator protein, commonly the reverse tet-transactivator, rtTA. Most rtTA strains rely on tissue specific promoters that often do not provide sufficient rtTA levels for optimal inducible expression. Here we describe the generation of two mouse strains that enable Cre-dependent, robust expression of rtTA3, providing tissue-restricted and consistent induction of TRE-controlled transgenes. We show that these transgenic strains can be effectively combined with established mouse models of disease, including both Cre/LoxP-based approaches and non Cre-dependent disease models. The integration of these new tools with established mouse models promises the development of more flexible genetic systems to uncover the mechanisms of development and disease pathogenesis.

    The regulation of the electric power industry is presently experiencing significative changes world-wide at an unprecedented pace. In these circumstances it is useless to attempt the preparation of a static snapshot of the current situation, because of the difficulties in capturing the exact position of each player and also because the picture would become obsolete in a very short time. This paper presents the specific features characterising power organisation, the regulatory approaches to the several services involved in supplying electricity, and alternative schemes for introduction of different levels of competition in traditionally regulated electric systems.

    2011-01-01

    To suggest a scheme of decision making on pricing for medicines that are part of Free Regulated Regime, a regulation way of the pharmaceutical pricing policy in Colombia. It includes two regulation tools: international reference prices and a cost minimization analysis methodology. Following the current pricing policy, international reference prices were built with data from five countries for selected medicines, which are under Free Regulated Regime. The cost minimization analysis methodology includes selection of those medicines under Free Regulated Regime with possible comparable medicines, selection of comparable medicines, and treatment costs evaluation. As a result of the estimate of International Reference Prices, four medicines showed in the domestic pharmaceutical market a bigger price than the Reference Price. A scheme of decision-making was design containing two possible regulation tools for medicines that are part of Free Regulated Regime: estimate of international reference prices and cost minimization analysis methodology. This diagram would be useful to assist the pricing regulation of Free Regulated Regime in Colombia. As present results shows, international reference prices make clear when domestic prices are higher than those of reference countries. In the current regulation of pharmaceutical prices in Colombia, the international reference price has been applied for four medicines. Would be suitable to extend this methodology to other medicines of high impact on the pharmaceutical expenditure, in particular those covered by public funding. The availability of primary sources about treatment costs in Colombia needs to be improved as a requirement to develop pharmaco-economic evidence. SISMED is an official database that represents an important primary source of medicines prices in Colombia. Nevertheless, having into account that SISMED represents an important advantage of transparency in medicines prices, it needs to be improved in quality and data

    Full Text Available As the result of the annexation of the Crimea and Donbass military conflict, there was an emergence of forced migration. It ought to be emphasized that today issues related to addressing problems of internally displaced persons (IDPs, are relevant and require an integrated approach. The increase in the number of IDPs in the country raises the issue of identifying the strategic priorities of the state policy. The purpose of this research is to formulate strategic priorities of the state policy of support for IDPs’. The subject of the study is theoretical and methodological principles of the state policy to support IDPs. The research methodology includes a set of scientific research methods that provide identifying the strategic priorities of the state policy for IDPs’ support, developing effective mechanisms for these priorities achievement, and conceptual vision of solving IDPs’ problems. In the course of investigations, the following methods are used: analysis while studying the main problems of internally displaced persons; logical synthesis and synthesis while drawing conclusions. Results. Scientific novelty of the article. In the article, the conceptual foundations of the IDPs support have been formed, an attention has been focused on the feasibility of using a strategic approach, which involves the formation and implementation of a set of strategically oriented measures aimed at solving the most acute issues and matters related to internal forced migration, directing the IDPs potential and internally displaced businesses to strengthen local communities and social and economic development of the resettlement territories. The main stages and conceptual foundations for the Strategy formation on the IDPs support have been proposed. The strategy is based on an integrated approach to addressing IDPs and internally displaced businesses, taking into account the interests of host communities. Practical implications.

    Diverse international organizations have evaluated the risk of lung cancer starting from epidemic studies in miners of uranium mines, where the corresponding effective dose was determined relating with the dose received by the population during Hiroshima and Nagasaki events. Alternately, the equivalent dose has been calculated by means of based models on the energy deposited by the breathable radon fractions and its decay products in the breathing ducts. A unique factor agreed by the diverse organizations that allows converting radon concentration to effective dose does not exist. Neither an agreement exists among the different countries on which duty to be the value of the maximum concentration of radon, in interiors starting from which an intervention is required and if this intervention is standardized, recommended or nonexistent. In this work study cases in Mexico are presented and their interpretation alternative based on the international agreements absence. (Author)

  5. An international comparison of the outcomes of environmental regulation

    Gouldson, Andy; Carpenter, Angela; Afionis, Stavros

    2014-01-01

    Whilst there is much discussion about the stringency of environmental regulations and the variability of industrial environmental performance in different countries, there are very few robust evaluations that allow meaningful comparisons to be made. This is partly because data scarcity restricts the ability to make ‘like for like’ comparisons across countries and over time. This paper combines data on benzene emissions from Pollution Release and Transfer Registers with data on industrial production from oil refineries to generate normalized measures of industrial environmental performance across eight Organisation for Economic Cooperation and Development countries and the EU-15. We find that normalized emissions levels are improving in nearly all countries, and that there is some convergence in emissions performance between countries, but that there are still very significant variations across countries. We find that average emissions levels are lower in Japan and Germany than in the USA and Australia, which in turn are lower than in Canada and the EU-15, but we note that average emissions in the EU-15 are significantly affected by particularly high emissions in the UK. These findings have significant implications for wider debates on the stringency of environmental regulations and the variability of industrial environmental performance in different countries.

  9. International perspective on regulation and radioactive waste management

    International Nuclear Information System (INIS)

    Brennecke, P.W.

    2001-01-01

    In recent years, within the framework of national as well as international programmes, notable advances and considerable experience have been reached, in particular in the areas of minimisation of the production of radioactive waste, conditioning and disposal of short-lived low and intermediate level waste, vitrification of fission product solution on an industrial scale and engineered storage of long-lived high level waste, i.e. vitrified waste and spent fuel. Based on such results near-surface repositories have successfully been operated in many countries. Furthermore, geological repository development programmes are now being pursued, addressing the development and application of appropriate methods for site-specific safety assessments, too. In addition to scientific-technical areas, issues regarding economical, environmental, ethical and political aspects have been considered increasingly during the last years. Hence, there is a need for the examination of such issues in more detail and, if appropriate, for introducing respective results in further radioactive waste management and disposal options and/or planning work. Taking differences in national approaches, practices and constraints into account, it is to be recognised that future developments and decisions will have to be extended in order to include further important aspects and, finally, to enhance acceptance and confidence in safety-related planning work as well as proposed radioactive waste management and disposal solutions. In particular, international expertise and peer reviews are to be integrated. (author)

  10. Involvement of Trichoderma asperellum strain T6 in regulating iron acquisition in plants.

    2014-07-01

    Iron (Fe) deficiency is a major plant nutritional disorder in many parts of the world, particularly in areas with saline soils. Among the numerous root-associated microbes that are beneficial for plant nutrient uptake, Trichoderma spp. are the most effective rhizosphere fungi for enhancing plant growth and plant resistance to biotic and abiotic stresses. To investigate the potential mechanisms of action of Trichoderma on insoluble Fe in the soil, which is difficult for plants to absorb and utilize, a high siderophore-producing strain of Trichoderma T6, was isolated from the rhizosphere of cucumber plants. The strain was identified as T. asperellum based on the morphological features and molecular phylogenetic analyses. Applying strain T6 to sterile soil could increase soil levels of Fe(2+) and siderophores, as well as increase Fe(2+) and Fe(3+)-chelate reductase (FCR) activity in cucumber tissues. Purified siderophore eluent (PSE) increased plant growth, thus confirming its role in plant growth promotion. Moreover, extracellular Fe(3+) reducing activity and three kinds of organic acids were detected in the culture filtrate of strain T6. These results indicate that strain T6 influences plant Fe absorption in several ways. Siderophore-based Fe chelation is effective in providing Fe to plants, organic acids, and Fe(3+) reducing enzymes may participate in the solubilization and reduction of insoluble Fe(3+) to Fe(2+). © 2014 WILEY-VCH Verlag GmbH & Co.

  11. Three Australian whistleblowing sagas: lessons for internal and external regulation.

    Faunce, Thomas A; Bolsin, Stephen N C

    2004-07-05

    The protracted and costly investigations into Camden and Campbelltown hospitals (New South Wales), The Canberra Hospital (Australian Capital Territory), and King Edward Memorial Hospital (Western Australia) recently uncovered significant problems with quality and safety at these institutions. Each investigation arose after whistleblowers alerted politicians directly, having failed to resolve the problems using existing intra-institutional structures. None of the substantiated problems had been uncovered or previously resolved by extensive accreditation or national safety and quality processes; in each instance, the problems were exacerbated by a poor institutional culture of self-regulation, error reporting or investigation. Even after substantiation of their allegations, the whistleblowers, who included staff specialists, administrators and nurses, received little respect and support from their institutions or professions. Increasing legislative protections indicate the role of whistleblowers must now be formally acknowledged and incorporated as a "last resort" component in clinical-governance structures. Portable digital technology, if adequately funded and institutionally supported, may help to transform the conscience-based activity of whistleblowing into a culture of self-reporting, linked to personal and professional development.

  12. International and European regulations in the energy law: selected issues

    International Nuclear Information System (INIS)

    Schwarz, F.

    2010-01-01

    This work deals with four selected legal aspects or issues in the energy sector, which are mainly located in the international, European and at the interface to national law. The first question is 'The status of the investor to the Energy Charter' and addresses issues regarding the investor position and their characteristics according to the Energy Charter Treaty. The second question is 'aspects of energy competence under the Treaty of Lisbon' and deals among others questions with the new energy expertise offense, as well as direct investment. The third issue, titled 'The admissibility of ownership unbundling' illuminates terms of a proposal, which plan a full ownership unbundling of transmission system operators, in more detail. The fourth issue is 'aspects for the implementation of directive 2006/32/EC' and deals with aspects of the implementation of this directive in Austria. This work is making an attempt to shed light on these questions and their issues in more detail by also taking into account the Austrian perspectives. In my view the energy sector is an economically important and politically embossed area that always has a current relevance to daily life and will raise more legal questions in future. (kancsar) [de

  13. Regulation of international energy markets: Economic effects of political actions

    Shcherbakova, Anastasia V.

    's participation in a regulated market results in an average decline in its stock returns of up to 50 basis points per day, and a cumulative loss of more than 3.5% of its market value. Negative shocks to securities returns persist for at least two months. Participation in a regulated market, however, is not always unfavorable, as involved firms not directly targeted by regulatory action appear to gain sizable risk premiums. Additional evidence suggests that, although there is no direct linear relationship between firm size and effect magnitude, large firms tend to be hurt more in the short term, while small firms suffer bigger declines in returns over a longer time period. The last chapter turns to global electricity sectors to examine the development of Demand Response (DR) programs, which have become popular means of addressing the sector's central market failure of pricing below marginal generation cost. DR programs incorporate demand signals into retail electricity rates, and have the potential to effectively and inexpensively improve grid reliability and increase end-use efficiency. However, DR faces many challenges, arguably the most important of which is a general lack of information among consumers regarding usage levels and existence of alternative providers and rate plans. Financial considerations, lack of access to technological infrastructure, and misaligned producer incentives also play an important role in DR's limited success.

    The aim of the worksite study is to elucidate the strain reducing impact of different forms of spending lunch breaks. With the help of the so-called silent room cabin concept, it was possible to induce a lunch-break relaxation opportunity that provided visual and territorial privacy. To evaluate the proposed effects, 14 call center agents were assigned to either 20 min progressive muscle relaxation (PMR) or small-talk (ST) break groups. We analyzed the data in a controlled trial for a period of 6 months (every 2 months four measurements a day at 12:00, 13:00, 16:00, 20:00) using independent observer and self-report ratings of emotional, mental, motivational, and physical strain. Results indicated that only the PMR break reduced postlunchtime and afternoon strain. Although further intervention research is required, our results suggest that PMR lunch break may sustainable reduce strain states in real worksite settings. Copyright 2010 APA, all rights reserved.

    Thrust sheets accumulate internal strain before they start moving along discrete fault planes. However, there are no previous studies evaluating the time difference between initiation of strain and fault displacement. In this paper we use observations from the Eastern Cordillera of Colombia to evaluate this interval. We utilize multiple thermochronometers and paleothermometers to refine the timing of deformation. Based on these new data we build time-temperature path estimates that together with geometric outcrop-based structural analysis and fluid inclusions allow us to assign relative timing to features associated with strain, such as cleavage, veins and certain types of fractures, and compare that with the timing of thrusting. We find that cleavage was only formed close to maximum paleotemperatures, almost coeval with the onset of thrust-induced denudation by the Late Oligocene. The corresponding structural level of fold-related veins suggest that they were formed later but still when the country rocks were at temperatures higher than 160 °C, mostly during the Early Miocene and still coexisted with the latest stages of cleavage formation. Our data show that the main period of strain hardening was short (probably a few million years) and occurred before first-order basement thrusting was dominant, but was associated with second-order folding.

    The potential relationship between domestic environmental regulation and international competitiveness has evoked various speculations. The common neoclassical train of thought is that strict environmental regulation is detrimental to the competitiveness of industry, and that it induces phenomena such as ecological dumping, ecological capital flight, and regulatory 'chill' in environmental standards. A different view is that strict environmental regulation triggers industry's innovation potential, and subsequently increases its competitiveness. The impact of environmental regulation on competitiveness has been analyzed in terms of international capital movements, new firm formation, and international trade. This paper focuses on a statistically rigorous analysis of international trade studies, using a technique that is known as meta-analysis. The paper presents a statistically supported evaluation of the literature, in order to assess what the main conclusions regarding the relationship between environmental regulation and competitiveness are when it comes to studies on international trade flows. The synthesis of the literature is subsequently used to present guidelines for future primary research in this area.

    The remarkable mechanical properties of biological structures, like tooth and bone, are often a consequence of their architecture. The tree ring-like layers that comprise the skeletal elements of the marine sponge Euplectella aspergillum are a quintessential example of the intricate architectures prevalent in biological structures. These skeletal elements, known as spicules, are hair-like fibers that consist of a concentric array of silica cylinders separated by thin, organic layers. Thousands of spicules act like roots to anchor the sponge to the sea floor. While spicules have been the subject of several structure-property investigations, those studies have mostly focused on the relationship between the spicule's layered architecture and toughness properties. In contrast, we hypothesize that the spicule's layered architecture enhances its bending failure strain, thereby allowing it to provide a better anchorage to the sea floor. We test our hypothesis by performing three-point bending tests on E. aspergillum spicules, measuring their bending failure strains, and comparing them to those of spicules from a related sponge, Tethya aurantia. The T. aurantia spicules have a similar chemical composition to E. aspergillum spicules but have no architecture. Thus, any difference between the bending failure strains of the two types of spicules can be attributed to the E. aspergillum spicules' layered architecture. We found that the bending failure strains of the E. aspergillum spicules were roughly 2.4 times larger than those of the T. aurantia spicules. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The characteristics of the residual stresses and their effects on the properties in continuous SiC fiber reinforced Ti-6Al-4V matrix composites (TMCs) have been extensively studied. However, to date, few experimental studies (e.g. Ti-14Al-21Nb/SCS-6) have characterized the thermal residual strain in TMCs at elevated temperatures. Therefore, the authors investigated the evolution of the thermal residual strain during heating of Ti-6Al-4V/35vol% SiC composite. In this study the authors used in situ high temperature neutron diffraction to measure strains: (1) in the matrix (α and β phases) and in the fiber, (2) for several lattice reflections in each phase and (3) from both axial and the transverse directions. One distinguishing feature is the wide temperature range (from room temperature up to 1,170K) over which the study was performed. Although the proposed application temperature is typically less than 800K, TMCs are subject to higher temperatures during fabrication and may experience high temperature excursions while in service. Therefore, the authors extended the study to the high temperature regime where the matrix starts to undergo a phase transformation between αminus and βminusTi. Measurements from this regime (800approximately1,170K) provide insights on; (1) the inelastic relaxation of the residual strains through matrix yielding and creep, (2) the effect of the phase transformation on the residual strains and (3) the effect of the presence of SiC on the matrix phase evolution

  2. Characterization of the biocontrol activity of pseudomonas fluorescens strain X reveals novel genes regulated by glucose.

    Gerasimos F Kremmydas

    Full Text Available Pseudomonas fluorescens strain X, a bacterial isolate from the rhizosphere of bean seedlings, has the ability to suppress damping-off caused by the oomycete Pythium ultimum. To determine the genes controlling the biocontrol activity of strain X, transposon mutagenesis, sequencing and complementation was performed. Results indicate that, biocontrol ability of this isolate is attributed to gcd gene encoding glucose dehydrogenase, genes encoding its co-enzyme pyrroloquinoline quinone (PQQ, and two genes (sup5 and sup6 which seem to be organized in a putative operon. This operon (named supX consists of five genes, one of which encodes a non-ribosomal peptide synthase. A unique binding site for a GntR-type transcriptional factor is localized upstream of the supX putative operon. Synteny comparison of the genes in supX revealed that they are common in the genus Pseudomonas, but with a low degree of similarity. supX shows high similarity only to the mangotoxin operon of Ps. syringae pv. syringae UMAF0158. Quantitative real-time PCR analysis indicated that transcription of supX is strongly reduced in the gcd and PQQ-minus mutants of Ps. fluorescens strain X. On the contrary, transcription of supX in the wild type is enhanced by glucose and transcription levels that appear to be higher during the stationary phase. Gcd, which uses PQQ as a cofactor, catalyses the oxidation of glucose to gluconic acid, which controls the activity of the GntR family of transcriptional factors. The genes in the supX putative operon have not been implicated before in the biocontrol of plant pathogens by pseudomonads. They are involved in the biosynthesis of an antimicrobial compound by Ps. fluorescens strain X and their transcription is controlled by glucose, possibly through the activity of a GntR-type transcriptional factor binding upstream of this putative operon.

    Mannitol has been widely used in fine chemicals, pharmaceutical industries, as well as functional foods due to its excellent characteristics, such as antioxidant protecting, regulation of osmotic pressure and non-metabolizable feature. Mannitol can be naturally produced by microorganisms. Compared with chemical manufacturing, microbial production of mannitol provides high yield and convenience in products separation; however the fermentative process has not been widely adopted yet. A major obstacle to microbial production of mannitol under industrial-scale lies in the low economical efficiency, owing to the high cost of fermentation medium, leakage of fructose, low mannitol productivity. In this review, recent advances in improving the economical efficiency of microbial production of mannitol were reviewed, including utilization of low-cost substrates, strain development for high mannitol yield and process regulation strategies for high productivity.

  4. Incentive-based regulation of CO2 emissions from international aviation

    2002-01-01

    We explore the possibilities of using incentive-based environmental regulations of CO 2 emissions from international civil aviation. In theory incentive-based instruments such as an emission charge or a tradable emission permit system are better regulations than so-called command-and-control regulations such as emission limits or technology standards. However, the implementation of these instruments is a complex issue. We therefore describe and discuss how an emission charge and a tradable emission permit system for international aviation should be designed in order to improve efficiency. We also compare these two types of regulations. In brief, we find that an emission charge and a tradable emission permit system in which the permits are auctioned have more or less the same characteristics. The main advantage of a tradable emission permit system is that the effect, in terms of emission reductions, is known. On the other hand, we show that under uncertainty an emission charge is preferred. The choice of regulation is a political decision and it does not seem likely that an environmental charge or a tradable emission permit system would be implemented without consideration of the costs of the regulation. Revenue-neutral charges or gratis distribution of permits would, for this reason, be realistic choices of regulations. However, such actions are likely to result in less stringent regulations and other negative welfare effects.(author)

    An evaluation of the internal radiation dose received by workers between 1984 and 1994 was performed, after a brief description of IPEN facility. The National and International Recommendation aims to reduce the workers' doses below 1/10 of the annual limits. The routine monitoring should be eliminated, if the individual annual dose is below 3/10 of the annual limits. In this case, only the operational monitoring should be maintained. In principle, the concept of restricted area should be reviewed, because, according to Publication 26 of ICRP, 1977, it should be a supervised area instead. The new concept of restricted area recommended by the Publication 60, ICRP 1991, should be adjusted accordingly. Thus, the classification used by the Commission-controlled areas and supervised areas will be with the foreseeable dose and not with the actual dose. When the individual annual dose is kept below 1/10 of the annual limits, the routine monitoring is not necessary, and only operational monitoring is needed. Finally, the future possible activities of the Individual Internal Dosimetry Laboratory at IPEN are discussed, after the elimination of individual monitoring. (authors). 8 refs

  10. The cochaperone BAG3 coordinates protein synthesis and autophagy under mechanical strain through spatial regulation of mTORC1.

    The cochaperone BAG3 is a central protein homeostasis factor in mechanically strained mammalian cells. It mediates the degradation of unfolded and damaged forms of the actin-crosslinker filamin through chaperone-assisted selective autophagy (CASA). In addition, BAG3 stimulates filamin transcription in order to compensate autophagic disposal and to maintain the actin cytoskeleton under strain. Here we demonstrate that BAG3 coordinates protein synthesis and autophagy through spatial regulation of the mammalian target of rapamycin complex 1 (mTORC1). The cochaperone utilizes its WW domain to contact a proline-rich motif in the tuberous sclerosis protein TSC1 that functions as an mTORC1 inhibitor in association with TSC2. Interaction with BAG3 results in a recruitment of TSC complexes to actin stress fibers, where the complexes act on a subpopulation of mTOR-positive vesicles associated with the cytoskeleton. Local inhibition of mTORC1 is essential to initiate autophagy at sites of filamin unfolding and damage. At the same time, BAG3-mediated sequestration of TSC1/TSC2 relieves mTORC1 inhibition in the remaining cytoplasm, which stimulates protein translation. In human muscle, an exercise-induced association of TSC1 with the cytoskeleton coincides with mTORC1 activation in the cytoplasm. The spatial regulation of mTORC1 exerted by BAG3 apparently provides the basis for a simultaneous induction of autophagy and protein synthesis to maintain the proteome under mechanical strain.

    2008-05-01

    Full Text Available Abstract Background A metabolic regulation study was performed, based upon measurements of enzymatic activities, fermentation performance, and RT-PCR analysis of pathways related to central carbon metabolism, in an ethanologenic Escherichia coli strain (CCE14 derived from lineage C. In comparison with previous engineered strains, this E coli derivative has a higher ethanol production rate in mineral medium, as a result of the elevated heterologous expression of the chromosomally integrated genes encoding PDCZm and ADHZm (pyruvate decarboxylase and alcohol dehydrogenase from Zymomonas mobilis. It is suggested that this behavior might be due to lineage differences between E. coli W and C. Results This study demonstrated that the glycolytic flux is controlled, in this case, by reactions outside glycolysis, i.e., the fermentative pathways. Changes in ethanol production rate in this ethanologenic strain result in low organic acid production rates, and high glycolytic and ethanologenic fluxes, that correlate with enhanced transcription and enzymatic activity levels of PDCZm and ADHZm. Furthermore, a higher ethanol yield (90% of the theoretical in glucose-mineral media was obtained with CCE14 in comparison with previous engineered E. coli strains, such as KO11, that produces a 70% yield under the same conditions. Conclusion Results suggest that a higher ethanol formation rate, caused by ahigher PDCZm and ADHZm activities induces a metabolic state that cells compensate through enhanced glucose transport, ATP synthesis, and NAD-NADH+H turnover rates. These results show that glycolytic enzymatic activities, present in E. coli W and C under fermentative conditions, are sufficient to contend with increases in glucose consumption and product formation rates.

    CIEP was strongly involved in the preparation of the discussions on the regulation of gas markets at the World Gas Conference in Amsterdam, 6-9 June 2006. CIEP's new study on gas market regulation served as the starting note for the strategic panel discussion 'The art of regulation'. It combines a theoretical foundation for the discussion on gas market regulation with the outcomes of a series of workshops, which addressed gas market regulation in various parts of the world. In particular, the authors aimed at examining whether changing circumstances in international gas markets require adaptations in current regulatory regimes.The study highlights that the regulation of gas markets, made up of elements such as international agreements, licensing and permitting procedures, competition policy, consumer protection and network access regulation, needs to take the specific regional circumstances of the gas market in question into account. There is no 'one size fits all' solution that is applicable to all gas markets in order to bring about the investments necessary

    In a closed water-tunnel circuit, the multi-component strain gauge force and moment sensor (also known as balance) are generally used to measure hydrodynamic forces and moments acting on scaled models. These balances are periodically calibrated by static loading. Their performance and accuracy depend significantly on the rig and the method of calibration. In this research, a new calibration rig was designed and constructed to calibrate multi-component internal strain gauge balances. The calibration rig has six degrees of freedom and six different component-loading structures that can be applied separately and synchronously. The system was designed based on the applicability of formal experimental design techniques, using gravity for balance loading and balance positioning and alignment relative to gravity. To evaluate the calibration rig, a six-component internal balance developed by Iran University of Science and Technology was calibrated using response surface methodology. According to the results, calibration rig met all design criteria. This rig provides the means by which various methods of formal experimental design techniques can be implemented. The simplicity of the rig saves time and money in the design of experiments and in balance calibration while simultaneously increasing the accuracy of these activities.

    A comparative study on the nature of defects and their relationship to charge trapping with enhanced photosensitivity has been investigated through magnetic resonance and internal photoemission (IPE) experiments for rapid thermal grown oxides (RTO) on strained-Si/Si 0.8 Ge 0.2 and on co-processed bulk-Si (1 0 0) substrates. Both the band and defect-related electronic states were characterized through EPR, IPE, C-V and I-V measurements under UV-illumination. Surface chemical characterization of as-grown ultrathin oxides (5-7 nm) has been performed using high-resolution XPS. Enhancement in Ge-segregation with increasing oxidation temperature is reported. Comparative studies on interface properties and leakage current behavior of rapid thermal oxides have also been studied through fabricating metal-oxide-semiconductor capacitor structures. A degraded electrical property with increasing oxidation temperature is reported. Constant voltage stressing (CVS) in the range of 5.5-7 V was used to study the breakdown characteristics of different samples. We observe a distinguishably different time-to-breakdown (t bd ) phenomenon for bulk-Si and strained-Si/SiGe samples. Whereas the oxide on bulk-Si shows a typical breakdown behavior, the RTO grown oxide on strained-Si/SiGe samples showed a quasi-or soft-breakdown with lower t bd value. It may be pointed out that quasi-breakdown may be a stronger reliability limiting factor for strained-Si/SiGe devices in the oxide thickness range studied

    2017-01-01

    ABSTRACT Objective To evaluate the composition of the Internal Regulation Committees created in hospitals of a capital city. Methods A cross-sectional descriptive study assessing the structure, processes and results of each Committee. Results The main reasons for implementing the committees were legal issues and overcrowding in the emergency department. The most monitored indicators were the occupancy rate and the mean length of stay, and the most observed results were reductions in the latter. Institutional protocols were developed in 70% of cases, and the degree of support that the Internal Regulation Committee received from the hospital managers was high, despite being only average the support received from the medical teams. Promoting the efficient use of beds seemed to be the main goal. To achieve it, the Internal Regulation Committee had to control hospital capacity at levels that allowed proper and safe bed turnover for patients. The strategies for this were varied and needed to integrate administrative and care issues. Conclusion The Internal Regulation Committees were a management tool with great potential and promising results in the experiences evaluated. PMID:29091157

    Nanotechnology offers potential in pharmaceuticals and biomedical developments for improving drug delivery systems, medical imaging, diagnosis, cancer therapy, and regenerative medicine. Although there is no international regulation or legislation specifically for nanomedicine, it is agreed worldwide that considerably more attention should be paid to the quality, safety, and efficacy of nanotechnology-based drugs. The US Food and Drug Administration and the European Medicines Agency have provided several draft regulatory guidance and reflection papers to assist the development of nanomedicines. To cope with the impact of nanotechnology and to foster its pharmaceutical applications and development in Taiwan, this article reviews the trends of regulating nanotechnology-based pharmaceuticals in the international community and proposes strategies for Taiwan's regulation harmonized with international considerations. The draft regulatory measures include a chemistry, manufacturing, and controls (CMC) review checklist and guidance for CMC review of liposomal products. These have been submitted for discussion among an expert committee, with membership comprised of multidisciplinary academia, research institutions, the pharmaceutical industry, and regulators, and are currently approaching final consensus. Once a consensus is reached, these mechanisms will be recommended to the Taiwan Food and Drug Administration for jurisdiction and may be initiated as the starting point for regulating nanotechnology-based pharmaceuticals in Taiwan.

    In contrast to other members of the EGF receptor family, ErbB3 is constitutively internalized in a clathrin-dependent manner. Previous studies have shown that ErbB3 does not interact with the coated pit localized adaptor complex 2 (AP-2), and that ErbB3 lacks two AP-2 interacting internalization signals identified in the EGF receptor. Several other clathrin-associated sorting proteins which may recruit cargo into coated pits have, however, been identified, and the study was performed to identify adaptors needed for constitutive internalization of ErbB3. A high-throughput siRNA screen was used to identify adaptor proteins needed for internalization of ErbB3. Upon knock-down of candidate proteins internalization of ErbB3 was identified using an antibody-based internalization assay combined with automatic fluorescence microscopy. Among 29 candidates only knock-down of epsin 1 turned out to inhibit ErbB3. Epsin 1 has ubiquitin interacting motifs (UIMs) and we show that ErbB3 interacts with an epsin 1 deletion mutant containing these UIMs. In support of an ErbB3-epsin 1 UIM dependent interaction, we show that ErbB3 is constitutively ubiquitinated, but that both ubiquitination and the ErbB3-epsin 1 interaction increase upon ligand binding. Altogether the results are consistent with a model whereby both constitutive and ligand-induced internalization of ErbB3 are regulated through interaction with epsin 1. Internalization is an important regulator of growth factor receptor mediated signaling and the current study identify mechanisms regulating plasma membrane turnover of ErbB3.

    Pregnant DBA/2J females built significantly larger and more completely enclosed nests than did pregnant C57BL/6J mice. This strain difference was restricted to the last half of gestation and was not observed during either the virgin state or lactation. Genotype-based differences in pregnancy-induced nest building were not related to circulating levels of progesterone (P), core temperature, or body weight. Exposure to supplemented P during pregnancy elevated nest building exhibited by pregnant C57BL females but did not induce DBA-like levels of the behavior. Also, virgin DBA females built larger nests in response to P than did C57BL females. These findings suggest that differences in the sensitivity of central neural tissue to steroid hormones may account for genotypically determined variation in patterns of pregnancy-induced nest building.

    2013-06-01

    Full Text Available This paper is a comparative analysis of the recent evolution of the French and the Anglo-Saxon profession regulations of auctioneers in terms of entry barriers and exercise of the profession. Firstly, following Stephen and Love's (1999 framework of the regulation of legal profession, we highlight the differences between regulations focussing on different levels (entry restrictions, advertising, fees, fee contracts, and organisational form. We show that French commissaire-priseurs and Anglo-Saxon auctioneers are bounded to quite opposed rules, relating to both the level of regulation (licensing against registration or certification and the scope of this regulation. Secondly, we try to assess the success of these regulations in terms of economic efficiency by comparing the international markets shares of French and Anglo-Saxon auctioneers. We further highlight how a weak regulation can disturb prices mechanisms and, in some cases, favour speculation. The discussion of some emblematic scandals highlights distortions provoked by a strong, as well as a weak regulation

  4. Regulating private human suborbital flight at the international and European level: Tendencies and suggestions

    Masson-Zwaan, Tanja; Moro-Aguilar, Rafael

    2013-12-01

    In the context of the FAST20XX project (Future High-Altitude High-Speed Transport) that started in 2009 under the 7th Framework Programme of the European Union (EU), the authors reexamined the legal status of private human suborbital flight, and researched whether it might be regulated as aviation or as spaceflight. International space law is ambiguous as to accommodating suborbital activities. While some provisions of the UN outer space treaties would seem to exclude them, generally there is not any explicit condition in terms of reaching orbit as a requirement for application. International air law presents equal difficulties in dealing with this activity. The classic definition of "aircraft" as contained in the Annexes to the Chicago Convention does not really encompass the kind of rocket-powered vehicles that are envisaged here. As a result, it is unclear whether the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), the International Civil Aviation Organization (ICAO), or both could be involved in an eventual international regulation of suborbital flight. In the absence of a uniform international regime, each state has the sovereign right to regulate human suborbital flights operating within its airspace. So far, two practical solutions have been realised or proposed, and will be analyzed. On the one hand, the USA granted power for regulation and licensing over private human suborbital flight to the Office of Commercial Space Transportation of the Federal Aviation Administration (FAA/AST). Subsequent regulations by the FAA have set out a series of requirements for companies that want to operate these flights, enabling a market to develop. On the other side of the Atlantic, both the European Space Agency (ESA) and a group of representatives of the European Aviation Safety Agency (EASA) of the European Union (EU) seem to rather regard this activity as aviation, potentially subject to the regulation and certification competences of EASA

    Growth of Synechococcus sp. strain PCC 7942 in iron-deficient media leads to the accumulation of an approximately 34-kDa protein. The gene encoding this protein, mapA (membrane-associated protein A), has been cloned and sequenced (GenBank accession number, L01621). The mapA transcript is not detectable in normally grown cultures but is stably accumulated by cells grown in iron-deficient media. However, the promoter sequence for this gene does not resemble other bacterial iron-regulated promoters described to date. The carboxyl-terminal region of the derived amino acid sequence of MapA resembles bacterial proteins involved in iron acquisition, whereas the amino-terminal end of MapA has a high degree of amino acid identity with the abundant, chloroplast envelope protein E37. An approach employing improved cellular fractionation techniques as well as electron microscopy and immunocytochemistry was essential in localizing MapA protein to the cytoplasmic membrane of Synechococcus sp. strain PCC 7942. When these cells were grown under iron-deficient conditions, a significant fraction of MapA could also be localized to the thylakoid membranes.

  6. HARMONIZATION OF NATIONAL REGULATION AND INTERNATIONAL FINANCIAL REPORTING STANDARDS – PARTICULAR CASE OF NONCURRENT ASSETS

    2013-07-01

    Full Text Available In the scientific literature, accounting harmonization is a top topic because it helps to increase the comparability of financial statements. Also in Romania in the last 10 years becames a topic that is very often debated. The harmonization is trying to reduce differences of financial reporting statements between countries or, in the other words, it is trying to bring to a common denominator of existing rules when appear conflicts of comparability between them. The purpose of this paper is to measure the harmonisation between national and international regulation for a significant element of financial position statement, such as noncurrent assets. This paper provides an empirical research of information that must be presented by entities which apply national accounting standards or international ones when financial statements are prepared, trying to measure the harmonization between the two referential. Thus, in trying to determine the harmonisation, we use the Jaccard coefficient in order to provide an overview of the degree of harmonization of accounting practice. When measuring the degree of comparability of Romanian accounting regulations with International Accounting Standards we analyzed noncurrent assets and impairment of assets using the Jaccard coefficient for accounting treatments and we calculated an average of similarities between the two regulations. Further, the results suggest that there is an average level of harmonization for the accounting treatment of noncurrent assets and for determining the impairment of the assets, the methods are the same. The study contributes to the development of accounting literature about the harmonisation between national regulation and international standards regarding the noncurrent assets and impairment of the assets, which together with the other elements define the activity of the business. In addition, the study provides an analysis of how the regulations treats noncurrent assets, during the

    Benchmarking of electricity networks has a key role in sharing the benefits of efficiency improvements with consumers and ensuring regulated companies earn a fair return on their investments. This paper analyses and contrasts the theory and practice of international benchmarking of electricity transmission by regulators. We examine the literature relevant to electricity transmission benchmarking and discuss the results of a survey of 25 national electricity regulators. While new panel data techniques aimed at dealing with unobserved heterogeneity and the validity of the comparator group look intellectually promising, our survey suggests that they are in their infancy for regulatory purposes. In electricity transmission, relative to electricity distribution, choosing variables is particularly difficult, because of the large number of potential variables to choose from. Failure to apply benchmarking appropriately may negatively affect investors’ willingness to invest in the future. While few of our surveyed regulators acknowledge that regulatory risk is currently an issue in transmission benchmarking, many more concede it might be. In the meantime new regulatory approaches – such as those based on tendering, negotiated settlements, a wider range of outputs or longer term grid planning – are emerging and will necessarily involve a reduced role for benchmarking. -- Highlights: •We discuss how to benchmark electricity transmission. •We report survey results from 25 national energy regulators. •Electricity transmission benchmarking is more challenging than benchmarking distribution. •Many regulators concede benchmarking may raise capital costs. •Many regulators are considering new regulatory approaches

    Listeria monocytogenes is a foodborne pathogen that can persist in food processing environments. Six persistent and six non-persistent strains from fish processing plants and one persistent strain from a meat plant were selected to determine if expression of genes in the regulons of two stress response regulators, σ(B) and CtsR, under salt stress conditions is associated with the ability of L. monocytogenes to persist in food processing environments. Subtype data were also used to categorize the strains into genetic lineages I or II. Quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) was used to measure transcript levels for two σ(B)-regulated genes, inlA and gadD3, and two CtsR-regulated genes, lmo1138 and clpB, before and after (t=10 min) salt shock (i.e., exposure of exponential phase cells to BHI+6% NaCl for 10 min at 37°C). Exposure to salt stress induced higher transcript levels relative to levels under non-stress conditions for all four stress and virulence genes across all wildtype strains tested. Analysis of variance (ANOVA) of induction data revealed that transcript levels for one gene (clpB) were induced at significantly higher levels in non-persistent strains compared to persistent strains (p=0.020; two-way ANOVA). Significantly higher transcript levels of gadD3 (p=0.024; two-way ANOVA) and clpB (p=0.053; two-way ANOVA) were observed after salt shock in lineage I strains compared to lineage II strains. No clear association between stress gene transcript levels and persistence was detected. Our data are consistent with an emerging model that proposes that establishment of L. monocytogenes persistence in a specific environment occurs as a random, stochastic event, rather than as a consequence of specific bacterial strain characteristics.

  9. Reporting of Outbreaks of Foodborne Illness under the International Health Regulations

    Centers for Disease Control (CDC) Podcasts

    During the past 20 years, the global food trade has increased and, with it, the potential for the spread of foodborne illnesses caused by imported foods. The World Health Organization in 2007 implemented new International Health Regulations which help guide reporting of foodborne outbreaks. In this podcast, CDC's Dr. Scott McNabb discusses a study in the September 2008 issue of the journal Emerging Infectious Diseases which analyzed foodborne outbreaks in Australia in the early part of this decade and assessed how many would have been reported under the current health regulations.

    ASBTRACT The spread of infectious disease represents a global threat and therefore remains a priority on the international public health agenda. The International Health Regulations (IHR) (2005) came into effect in June 2007 and provide a legal framework to which the 196 member states of the World Health Assembly agree to abide. 1 These regulations include implementation of protective, control and response measures at points of entry to a country (i.e. land borders, sea and airports), and of notification measures, all of which aim to prevent or limit the spread of disease while minimising disruption to international trade. The World Health Organization can apply and enforce IHR (2005) to any disease considered to pose a significant threat to international public health. This short paper focuses on 2 diseases; yellow fever and poliomyelitis, both of which have the potential to spread internationally. It will discuss the measures applied under IHR (2005) to minimize the threat, and explore the implications for both travelers and travel health advisors.

    The continuous emergence of new strains of canine parvovirus (CPV), poorly protected by current vaccination, is a concern among breeders, veterinarians, and dog owners around the world. Therefore, the understanding of the genetic variation in emerging CPV strains is crucial for the design of disease control strategies, including vaccines. In this paper, we obtained the sequences of the full-length gene encoding for the main capsid protein (VP2) of 11 canine parvovirus type 2 (CPV-2) Argentine representative field strains, selected from a total of 75 positive samples studied in our laboratory in the last 9 years. A comparative sequence analysis was performed on 9 CPV-2c, one CPV-2a, and one CPV-2b Argentine strains with respect to international strains reported in the GenBank database. In agreement with previous reports, a high degree of identity was found among CPV-2c Argentine strains (99.6-100% and 99.7-100% at nucleotide and amino acid levels, respectively). However, the appearance of a new substitution in the 440 position (T440A) in four CPV-2c Argentine strains obtained after the year 2009 gives support to the variability observed for this position located within the VP2, three-fold spike. This is the first report on the genetic characterization of the full-length VP2 gene of emerging CPV strains in South America and shows that all the Argentine CPV-2c isolates cluster together with European and North American CPV-2c strains.

    A comparative study on the effects of heat treatment, especially, the duration of the A15 reaction temperature plateau on the strain dependence of the critical current for an internal-tin processed Nb 3 Sn strand has been carried out. The strain dependence of the critical current is measured by a variable temperature Walter spiral probe that we have developed. It was shown that prolonged heat treatment can be a very effective way to improve the strain dependency. For a quantitative analysis, the measured data were analyzed with various proposed scaling laws: the scaling law based on strong-coupling theory, the modified deviatoric strain scaling law, and the interpolative scaling law. We found that there is a slight increase in the critical temperature and a substantial improvement in the maximum pinning force. The origin of improved strain dependency is further discussed.

    Internal friction in copper-0.4 to 7.6 at% nickel single crystals is measured as a function of strain amplitude at various temperatures. Analysis of the data on the amplitude-dependent internal friction yields the relation of effective stress and microplastic strain of the order of 10{sup -9}. The stress-strain responses thus obtained exhibit that the microplastic flow stress increases more rapidly on alloying than the macroscopic yield stress. The mean dislocation velocity is also evaluated from the internal-friction data, which corresponds well to the etch-pit data. It is shown that the dislocation motion is impeded by friction due to dispersed solute atoms. (orig.).

    Full Text Available Background & objectives: Hepatic scavenger receptor class B1 (SR-B1, a high-density lipoprotein (HDL receptor, is involved in the selective uptake of HDL-associated esterified cholesterol (EC, thereby regulates cholesterol homoeostasis and improves reverse cholesterol transport. Previously, we reported in euglycaemic obese rats (WNIN/Ob strain that feeding of vitamin A-enriched diet normalized hypercholesterolaemia, possibly through hepatic SR-B1-mediated pathway. This study was aimed to test whether it would be possible to normalize hypercholesterolaemia in glucose-intolerant obese rat model (WNIN/GR/Ob through similar mechanism by feeding identical vitamin A-enriched diet. Methods: In this study, 30 wk old male lean and obese rats of WNIN/GR-Ob strain were divided into two groups and received either stock diet or vitamin A-enriched diet (2.6 mg or 129 mg vitamin A/kg diet for 14 wk. Blood and other tissues were collected for various biochemical analyses. Results: Chronic vitamin A-enriched diet feeding decreased hypercholesterolaemia and normalized abnormally elevated plasma HDL-cholesterol (HDL-C levels in obese rats as compared to stock diet-fed obese groups. Further, decreased free cholesterol (FC and increased esterified cholesterol (EC contents of plasma cholesterol were observed, which were reflected in higher EC to FC ratio of vitamin A-enriched diet-fed obese rats. However, neither lecithin-cholesterol acyltransferase (LCAT activity of plasma nor its expression (both gene and protein in the liver were altered. On the contrary, hepatic cholesterol levels significantly increased in vitamin A-enriched diet fed obese rats. Hepatic SR-B1 expression (both mRNA and protein remained unaltered among groups.

    The transnational spread of communicable and non-communicable diseases has opened new vistas in the discourse of global health security. Emerging and re-emerging pathogens, according to exponents of globalization of public health, disrespect the geo-political boundaries of nation-states. Despite the global ramifications of health insecurity in a globalizing world, contemporary international law still operates as a classic inter-state law within an international system exclusively founded on a coalition of nation-states. This article argues that the dynamic process of globalization has created an opportunity for the World Health Organization to develop effective synergy with a multiplicity of actors in the exercise of its legal powers. WHO's legal and regulatory strategies must transform from traditional international legal approaches to disease governance to a "post-Westphalian public health governance": the use of formal and informal sources from state and non-state actors, hard law (treaties and regulations) and soft law (recommendations and travel advisories) in global health governance. This article assesses the potential promise and problems of WHO's new International Health Regulations (IHR) as a regulatory strategy for global health governance and global health security.

    2009-12-01

    Zoonoses have earned recognition as the source of serious problems for both public and animal health throughout the world. Emerging infectious diseases have been occurring at an unprecedented rate since the 1970s and a large proportion of these diseases are considered zoonotic. To aid in controlling zoonoses, countermeasures have been strengthened against these diseases and are maintained at both national and international levels. Atypical example of this international effort can be found in the revised International Health Regulations (2005), known as the IHR (2005), which were instituted by the World Health Organization and have been implemented since 2007. In Japan, the appropriate Ministries have established frameworks for controlling zoonoses that employ both administrative and scientific approaches to fulfill the demands of the IHR (2005). In this paper, the authors present the Japanese framework for controlling zoonoses, as a useful example for global public and animal health management in coming years.

    2009-01-01

    The present work deals with the creation, on the basis of experimental data, of the regulation maps for the 1 MW cogenerative internal combustion engine (ICE) installed at the Engineering Faculty of Perugia University. The regulation logic mapping is necessary for the development of a thermodynamic model of the engine behaviour to simulate the effects of possible malfunctions occurrence, such as deterioration or fouling not directly experienced on the engine. Such a work is carried out as a part of a more general research activity concerning the development of a diagnosis system for the cogenerative plant. Therefore, a first phase of the present work relates to the experimental data gathering campaign and the consequent data analysis to individuate the characteristic parameters of regulation. In the second phase, instead, a neural simulator of the control logic was developed on the basis of the experimental data for the engine operation at full load (initially considered at 980 kW) and during transitory. Consequently, through such a simulator the regulation maps of the engine were determined considering the variation range of all the characteristic parameters. Finally, a more accurate analysis of the experimental data relative to the dependence of the produced electric power at regimen on the fuel valve position, encouraged the authors to develop a further neural simulator able to reproduce the regulation commands for different values of the target power set for the regimen operation. Consequently, also the regulation mapping was revised obtaining a synthetic representation of the regulation logic useful for the implementation in the thermodynamic model of the engine dynamic behaviour

    Full Text Available Modern international security is a heterogeneous sphere that includes both state and nonstate actors. Legal status of some non-state actors is not always clear. This can be attributed mostly to the dynamics of the global processes. The emergence of new actors, their fast transformation and shift from old forms of activity to the new ones often outpace political and legal assessment of their nature, the impact on some other international trends and the implications of their use that may arise. States and international organizations together with business and non-governmental foundations have started to turn to private security actors more frequently. The fact that traditional methods of state violence are complemented by non-traditional forms influences the idea of violence in the society at large. The efficiency of non-state security actors and the speed they provide services with sometimes exceed the ones of civil servants' and outmaneuver state machine. However these advantages do not contribute to the legitimacy of these non-state actors. As a result during a certain period of time, sometimes a significant one, new actors perform having just a partial legitimacy and a vague accoun tability. Various approaches towards regulation of the abovementioned actors within the framework of national and regional legislation clarify their status in a way. But these measures are not enough for them to obtain legal status under the International Law so far. To address the problem a complex approach that would combine the existing International Law mechanisms with the developing self-regulation methods is needed.

  4. Comparison of German and international clearance regulations - chances and limits for harmonization

    Thierfeldt, S.; Schartmann, F.

    2005-01-01

    The regulations on clearance in the German nuclear regulatory framework (especially sect. 29 and Annexes III and IV of the Radiation Protection Ordinance) are comprehensive and well founded. Germany has developed some of its clearance levels in advance of recommendations issued by the EC. Therefore, there are differences between the German and international clearance regulations. That has been investigated by a working group on clearance of the German Commission on Radiological Protection (SSK) which has performed an analysis of differences and their reasons for clearance levels in Germany and other countries (UK, The Netherlands, Sweden, USA and others). Differences can mainly be explained by country specific approaches in scenarios. Differences especially for the most relevant nuclides are not significant from a radiological point of view. The level of radiological protection (trivial dose range, a few 10 μSv/a) is guaranteed in all countries. The international discussion on the international harmonisation of clearance levels (mainly within the scope of the OECD/NEA and IAEA) can be enlightened on the basis of these results. This discussion concentrates on the question how far a harmonisation of clearance level values is actually necessary and possible. The IAEA Safety Guide RS-G-1.7 'Application of the concepts of exclusion, exemption and clearance' is of particular importance, because it proposes a set of values which might in the long-term take the role of international unconditional clearance levels. International harmonisation is only relevant for unconditional clearance of those materials, which are traded in large quantities among countries, in particular metal scrap. Harmonisation of the values to the same order of magnitude is sufficient. (orig.)

    Constitutive and regulated internalization of cell surface proteins has been extensively investigated. The regulated internalization has been characterized as a principal mechanism for removing cell-surface receptors from the plasma membrane, and signaling to downstream targets of receptors. However, so far it is still not known whether the functional properties of remaining (non-internalized) receptor/channels may be regulated by internalization of the same class of receptor/channels. The N-methyl-D-aspartate receptor (NMDAR) is a principal subtype of glutamate-gated ion channel and plays key roles in neuronal plasticity and memory functions. NMDARs are well-known to undergo two types of regulated internalization - homologous and heterologous, which can be induced by high NMDA/glycine and DHPG, respectively. In the present work, we investigated effects of regulated NMDAR internalization on the activity of residual cell-surface NMDARs and neuronal functions. In electrophysiological experiments we discovered that the regulated internalization of NMDARs not only reduced the number of cell surface NMDARs but also caused an inhibition of the activity of remaining (non-internalized) surface NMDARs. In biochemical experiments we identified that this functional inhibition of remaining surface NMDARs was mediated by increased serine phosphorylation of surface NMDARs, resulting from the activation of protein kinase D1 (PKD1). Knockdown of PKD1 did not affect NMDAR internalization but prevented the phosphorylation and inhibition of remaining surface NMDARs and NMDAR-mediated synaptic functions. These data demonstrate a novel concept that regulated internalization of cell surface NMDARs not only reduces the number of NMDARs on the cell surface but also causes an inhibition of the activity of remaining surface NMDARs through intracellular signaling pathway(s). Furthermore, modulating the activity of remaining surface receptors may be an effective approach for treating receptor

    Full Text Available BACKGROUND: The international wildlife trade is a key threat to biodiversity. Temporal genetic marketplace monitoring can determine if wildlife trade regulation efforts such as the Convention on International Trade in Endangered Species (CITES are succeeding. Protected under CITES effective 1997, sturgeons and paddlefishes, the producers of black caviar, are flagship CITES species. METHODOLOGY/PRINCIPAL FINDINGS: We test whether CITES has limited the amount of fraudulent black caviar reaching the marketplace. Using mitochondrial DNA-based methods, we compare mislabeling in caviar and meat purchased in the New York City area pre and post CITES listing. Our recent sampling of this market reveals a decrease in mislabeled caviar (2006-2008; 10%; n = 90 compared to pre-CITES implementation (1995-1996; 19%; n = 95. Mislabeled caviar was found only in online purchase (n = 49 online/41 retail. CONCLUSIONS/SIGNIFICANCE: Stricter controls on importing and exporting as per CITES policies may be having a positive conservation effect by limiting the amount of fraudulent caviar reaching the marketplace. Sturgeons and paddlefishes remain a conservation priority, however, due to continued overfishing and habitat degradation. Other marine and aquatic species stand to benefit from the international trade regulation that can result from CITES listing.

  8. Physiological regulation of isocitrate dehydrogenase and the role of 2-oxoglutarate in Prochlorococcus sp. strain PCC 9511.

    Directory of Open Access Journals (Sweden)

    María Agustina Domínguez-Martín

    Full Text Available The enzyme isocitrate dehydrogenase (ICDH; EC 1.1.1.42 catalyzes the oxidative decarboxylation of isocitrate, to produce 2-oxoglutarate. The incompleteness of the tricarboxylic acids cycle in marine cyanobacteria confers a special importance to isocitrate dehydrogenase in the C/N balance, since 2-oxoglutarate can only be metabolized through the glutamine synthetase/glutamate synthase pathway. The physiological regulation of isocitrate dehydrogenase was studied in cultures of Prochlorococcus sp. strain PCC 9511, by measuring enzyme activity and concentration using the NADPH production assay and Western blotting, respectively. The enzyme activity showed little changes under nitrogen or phosphorus starvation, or upon addition of the inhibitors DCMU, DBMIB and MSX. Azaserine, an inhibitor of glutamate synthase, induced clear increases in the isocitrate dehydrogenase activity and icd gene expression after 24 h, and also in the 2-oxoglutarate concentration. Iron starvation had the most significant effect, inducing a complete loss of isocitrate dehydrogenase activity, possibly mediated by a process of oxidative inactivation, while its concentration was unaffected. Our results suggest that isocitrate dehydrogenase responds to changes in the intracellular concentration of 2-oxoglutarate and to the redox status of the cells in Prochlorococcus.

    During the past 20 years, the global food trade has increased and, with it, the potential for the spread of foodborne illnesses caused by imported foods. The World Health Organization in 2007 implemented new International Health Regulations which help guide reporting of foodborne outbreaks. In this podcast, CDC's Dr. Scott McNabb discusses a study in the September 2008 issue of the journal Emerging Infectious Diseases which analyzed foodborne outbreaks in Australia in the early part of this decade and assessed how many would have been reported under the current health regulations.  Created: 8/27/2008 by Emerging Infectious Diseases.   Date Released: 8/27/2008.

    Cellular microstructures within natural materials enlighten and promote the development of novel materials and structures in the industrial and engineering fields. Characterization of the microstructures and mechanical properties of these natural materials can help to understand the morphology-related mechanical properties and guide the structural optimization in industrial design. Among these natural cellular materials, pomelo peels, having a foam-like hierarchical microstructure, represent an ideal model for developing materials with high energy absorption efficiency. In this work, by combining X-ray tomographic imaging technique and digital volume correlation (DVC), in-situ stepwise uniaxial compression tests were performed to quantify the internal morphological evolution and kinematic responses of pomelo peel samples during compression. Via these experiments, the varying microstructure features and thus diverse resistance to compression from endocarp to exocarp are examined, and the evolution of both bundles bending and large strain domain from endocarp to mesocarp are explored. Based on the experimental results, the microstructure-related mechanical properties of pomelo peels in response to compressive loading that demonstrates nearly linear morphology-mechanics relationship were revealed.

  11. International experts conclude IAEA peer review of Iran's safety regulation of Bushehr NPP

    Full text: An international team of nuclear safety experts today completed an IAEA mission to review the effectiveness of Iran's safety regulation of its first nuclear power plant and to identify possible improvements before the plant begins operation. Upon invitation of the Islamic Republic of Iran, the International Atomic Energy Agency (IAEA) assembled a team of senior regulators from seven Member States for an Integrated Regulatory Review Service (IRRS) mission. The scope of the mission was limited to the safety regulation of Bushehr nuclear power plant (BNPP-1). The IRRS review took place from 20 February to 2 March at the INRA offices in Tehran and included a technical visit to the BNPP-1 site. The mission was an objective peer review based on IAEA safety standards, and was neither an inspection, nor an audit. Ms. Olena Mykolaichuk, IRRS Team Leader and Head of the State Nuclear Regulatory Committee of Ukraine, commended her INRA counterparts: 'The regulatory work performed on the Bushehr construction and in preparation for commissioning has demonstrated significant progress of INRA as a nuclear regulatory authority,' she said. Philippe Jamet, Director of the IAEA's Nuclear Installation Safety Division, added: 'Through this IRRS mission, both Iran and the international experts contribute to the enhancement of nuclear safety and worldwide experience sharing.' In the course of its review the IRRS team identified the following strengths: - INRA has a dedicated, conscientious staff, demonstrating clear commitments to further improvements. - INRA clearly recognizes the value of peer reviews and international cooperation regarding nuclear safety. - Despite a shortage of staff, INRA demonstrated strong leadership while performing both review and assessment and inspection tasks during the BNPP-1 construction and pre-commissioning. - INRA has developed an excellent computerized documentation control system. Recommendations and suggestions to improve INRA's regulatory

    Full text: Decree of Ministry of Health for the enforcement of the Act on Atomic Energy has put special emphasis on the regulation of monitoring for internal exposure in Hungary. The necessarily general prescription of the Decree 'In case of the possibility or suspicion of incorporating open radioactive substances the affected employee shall be subjected to internal contamination monitoring. The obligation of the internal monitoring shall be determined by the Radiation Hygiene Centre of the National Public Health and Medical Officer's Service' called for a guidance to assist the work of the competent authority. The guide was elaborated on the basis of the IAEA Safety Guide No. RS-G-1.2. According to the Safety Guide the decision factor shall first be determined for the potential radionuclides and practice applied. For routine monitoring the required frequency, method and MDA values, moreover for special monitoring the method and MDA values were derived for over 40 radionuclides considering the following two basic assumptions: the activity remaining in or excreted from the body could be determined by the given measurement method, the possible underestimation of intake shall be less than a factor of three within the monitoring interval. The following prescription of the Decree 'The laboratory performing the monitoring of internal exposure shall be accredited' has raised a conflict in practice. To solve the problem the Guide suggests a two-step monitoring process: a screening measurement for the possible internal contamination performed by the Radiation Protection Service of the workplace by any equipment used in daily practice for investigation of patients, radiation protection purposes, etc., if the result of screening indicates an internal contamination the radiation worker shall be monitored by an accredited laboratory. As an ISO Standard in process has several assumptions differing from the IAEA Safety Guide, e.g. the limitation of 'maximum potential

  13. γ-Aminobutyric Acid Type B (GABAB) Receptor Internalization Is Regulated by the R2 Subunit*

    γ-Aminobutyric acid type B (GABAB) receptors are important for slow synaptic inhibition in the CNS. The efficacy of inhibition is directly related to the stability of cell surface receptors. For GABAB receptors, heterodimerization between R1 and R2 subunits is critical for cell surface expression and signaling, but how this determines the rate and extent of receptor internalization is unknown. Here, we insert a high affinity α-bungarotoxin binding site into the N terminus of the R2 subunit and reveal its dominant role in regulating the internalization of GABAB receptors in live cells. To simultaneously study R1a and R2 trafficking, a new α-bungarotoxin binding site-labeling technique was used, allowing α-bungarotoxin conjugated to different fluorophores to selectively label R1a and R2 subunits. This approach demonstrated that R1a and R2 are internalized as dimers. In heterologous expression systems and neurons, the rates and extents of internalization for R1aR2 heteromers and R2 homomers are similar, suggesting a regulatory role for R2 in determining cell surface receptor stability. The fast internalization rate of R1a, which has been engineered to exit the endoplasmic reticulum, was slowed to that of R2 by truncating the R1a C-terminal tail or by removing a dileucine motif in its coiled-coil domain. Slowing the rate of internalization by co-assembly with R2 represents a novel role for GPCR heterodimerization whereby R2 subunits, via their C terminus coiled-coil domain, mask a dileucine motif on R1a subunits to determine the surface stability of the GABAB receptor.

    Multilevel models of developmental psychopathology implicate both characteristics of the individual and their rearing environment in the etiology of internalizing problems and disorders. Maladaptive regulation of fear and sadness, the core of anxiety and depression, arises from the conjoint influences of ineffective parasympathetic regulation of emotion and ineffective emotion socialization experiences. In 171 youths (84 female, M = 13.69 years, SD = 1.84), we measured changes of respiratory sinus arrhythmia (RSA) in response to sadness- and fear-inducing film clips and maternal supportive and punitive responses to youths' internalizing emotions. Youths and mothers reported on youths' internalizing problems and anxiety and depression symptoms concurrently and 2 years later at Time 2. Maternal supportive emotion socialization predicted fewer, and punitive socialization predicted more, mother-reported internalizing problems at Time 2 only for youths who showed RSA suppression to fear-inducing films. More RSA suppression to sadness-inducing films predicted more youth-reported internalizing problems at Time 2 in girls only. In addition, less supportive emotion socialization predicted more youth-reported depression symptoms at Time 2 only for girls who showed more RSA suppression to sadness. RSA suppression to sadness versus fear might reflect different patterns of atypical parasympathetic regulation of emotional arousal, both of which increase the risk for internalizing difficulties in youths, and especially girls, who lack maternal support for regulating emotions.

    Research has demonstrated the importance of early family characteristics, such as the quality of caregiving, on children's later mental health. Information is, however, needed about the role of more holistic family systems and specific child-related socioemotional mechanisms. In this study, we conceptualize families as dynamic family system types, consisting of both marital and parenting trajectories over the transition to parenthood. First, we examine how early family system types predict children's anxiety, depression, peer exclusion, and emotion regulation. Second, we test whether couples' infertility history and other family related contextual factors moderate the effects of family system types on child outcomes. Third, we test whether children's emotion regulation and peer exclusion mediate the effects of family system types on anxiety and depression. The participants were 452 families representing cohesive, distant, authoritative, enmeshed, and discrepant family types, identified on the basis of relationship autonomy and intimacy from pregnancy to the child's age of 2 and 12 months. Children's anxiety, depression, emotion regulation, and peer exclusion were assessed at the age of 7-8 years. Structural equation modeling showed that distant, enmeshed, and discrepant families similarly predicted children's heightened anxiety and depression. Infertility history, parental education, and parity moderated the associations between certain family system types and child outcomes. Finally, emotion regulation, but not peer exclusion, was a common mediating mechanism between distant and enmeshed families and children's depression. The results emphasize the importance of early family environments on children's emotion regulation development and internalizing psychopathology.

    The cell surface proteoglycan syndecan-4 has been reported to be crucial for muscle differentiation, but the molecular mechanisms still remain to be fully understood. During in vitro differentiation of bovine muscle cells immunocytochemical analyses showed strong labelling of syndecan-4 intracellularly, in close proximity with Golgi structures, in membranes of intracellular vesicles and finally, in the nuclear area including the nuclear envelope. Chase experiments showed that syndecan-4 was internalized from the plasma membrane during this process. Furthermore, when syndecan-4 was knocked down by siRNA more myotubes were formed, and the expression of myogenic transcription factors, β1-integrin and actin was influenced. However, when bovine muscle cells were treated with a cell-penetrating peptide containing the cytoplasmic region of syndecan-4, myoblast fusion and thus myotube formation was blocked, both in normal cells and in syndecan-4 knock down cells. Altogether this suggests that the cytoplasmic domain of syndecan-4 is important in regulation of myogenesis. The internalization of syndecan-4 from the plasma membrane during muscle differentiation and the nuclear localization of syndecan-4 in differentiated muscle cells may be part of this regulation, and is a novel aspect of syndecan biology which merits further studies.

    Full Text Available Synechocystis sp. strain PCC 6803 is the most widely studied model cyanobacterium, with a well-developed omics level knowledgebase. Like the lifestyles of other cyanobacteria, that of Synechocystis PCC 6803 is tuned to diurnal changes in light intensity. In this study, we analyzed the expression patterns of all of the genes of this cyanobacterium over two consecutive diurnal periods. Using stringent criteria, we determined that the transcript levels of nearly 40% of the genes in Synechocystis PCC 6803 show robust diurnal oscillating behavior, with a majority of the transcripts being upregulated during the early light period. Such transcripts corresponded to a wide array of cellular processes, such as light harvesting, photosynthetic light and dark reactions, and central carbon metabolism. In contrast, transcripts of membrane transporters for transition metals involved in the photosynthetic electron transport chain (e.g., iron, manganese, and copper were significantly upregulated during the late dark period. Thus, the pattern of global gene expression led to the development of two distinct transcriptional networks of coregulated oscillatory genes. These networks help describe how Synechocystis PCC 6803 regulates its metabolism toward the end of the dark period in anticipation of efficient photosynthesis during the early light period. Furthermore, in silico flux prediction of important cellular processes and experimental measurements of cellular ATP, NADP(H, and glycogen levels showed how this diurnal behavior influences its metabolic characteristics. In particular, NADPH/NADP+ showed a strong correlation with the majority of the genes whose expression peaks in the light. We conclude that this ratio is a key endogenous determinant of the diurnal behavior of this cyanobacterium.

The results showed the quickest biomass enhancement was induced by 50 mg·L−1 NAA, with a 6.3-fold increase over the control; the highest protein content was increased by 0.005 mg·L−1 ETH, which produced 3.5-fold over the control; total carotenoids content was induced most effectively by 1 mg·L−1 NAA with 3.6-fold higher production than the control; the most efficient elicitor for lipid production was 5 mg·L−1 GA3 at 1.9-fold of the control; 0.2 mg·L−1 ETH induced the abundant production of 1.82 ± 0.23% linoleic acid; 0.65 ± 0.01% linolenic acid was induced by 1 mg·L−1 NAA; 2.53 ± 0.15% arachidonic acid and 0.44 ± 0.05% docosahexaenoic acid were induced by 5 mg·L−1 GA3. Transcriptional expression levels of seven lipid-related genes, including ACP, BC, FAD, FATA, KAS, MCTK, and SAD, were studied by real-time RT-q-PCR. 5 mg·L−1 GA3 was the most effective regulator for transcriptional expressions of these seven genes, producing 23-fold ACP, 31-fold BC, 25-fold FAD, 6-fold KAS, 12-fold MCTK compared with the controls, respectively.

    Cyanobacteria are photoautotrophic microorganisms which fix atmospheric carbon dioxide via the Calvin-Benson cycle to produce carbon backbones for primary metabolism. Fixed carbon can also be stored as intracellular glycogen, and in some cyanobacterial species like Synechocystis sp. strain PCC 6803, polyhydroxybutyrate (PHB) accumulates when major nutrients like phosphorus or nitrogen are absent. So far only three enzymes which participate in PHB metabolism have been identified in this organism, namely, PhaA, PhaB, and the heterodimeric PHB synthase PhaEC. In this work, we describe the cyanobacterial PHA surface-coating protein (phasin), which we term PhaP, encoded by ssl2501. Translational fusion of Ssl2501 with enhanced green fluorescent protein (eGFP) showed a clear colocalization to PHB granules. A deletion of ssl2501 reduced the number of PHB granules per cell, whereas the mean PHB granule size increased as expected for a typical phasin. Although deletion of ssl2501 had almost no effect on the amount of PHB, the biosynthetic activity of PHB synthase was negatively affected. Secondary-structure prediction and circular dichroism (CD) spectroscopy of PhaP revealed that the protein consists of two α-helices, both of them associating with PHB granules. Purified PhaP forms oligomeric structures in solution, and both α-helices of PhaP contribute to oligomerization. Together, these results support the idea that Ssl2501 encodes a cyanobacterial phasin, PhaP, which regulates the surface-to-volume ratio of PHB granules. PMID:25911471

    This paper provides a summary and analysis of the regulation of ayahuasca in Brazil, from its prohibition in the mid-eighties to the recent adoption of CONAD's (Conselho Nacional de Políticas sobre Drogas) 2010 Resolution, which established a set of rules, norms and ethical principles to be applied to religious and ritual uses of ayahuasca. Brazil's regulatory process is used as a starting point to explore emerging international regulatory themes as various nations respond to the global expansion of the Santo Daime and UDV (União do Vegetal) ayahuasca religions. The text reviews the primary legislative and court documents, academic literature, as well as solicited expert opinions. Three prominent themes have emerged internationally. The first concerns the scope of international treaties regarding plant-based psychoactive substances, as well as the responsibilities of individual nations to adhere to said treaties. The second concerns the scope of religious liberty and how to determine religious legitimacy. The final theme addresses the potential dangers of ayahuasca to health and public safety. Over the past 20 years the Brazilian ayahuasca religions have established a global presence, with congregations in the USA, Canada, Japan, South Africa, Australia, and throughout Europe and Latin America. As a result, many nations are faced with the predicament of balancing the interests of these religious minorities with the international "war on drugs." The regulatory process applied in Brazil exemplifies a progressive approach, one which considered issues of anthropology and involved representatives of ayahuasca religions, and which provided a degree of deference to the principle of religious liberty. The Brazilian process has influenced judicial and administrative decisions internationally, and stands as a model worthy of further consideration. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full text: Senior nuclear regulators today concluded a Workshop on the Lessons Learned from the IAEA Integrated Regulatory Review Service (IRRS) Missions. The U.S. Nuclear Regulatory Commission (NRC) hosted the workshop, in cooperation with the International Atomic Energy Agency, in Washington, DC, from 26 to 28 October 2011. About 60 senior regulators from 22 IAEA Member States took part in this workshop. The IRRS programme is an international peer review service offered by the IAEA to its Member States to provide an objective evaluation of their nuclear safety regulatory framework. The review is based on the internationally recognized IAEA Safety Standards. ''The United States Nuclear Regulatory Commission was pleased to host the IAEA's IRRS meeting this week. The discussions over the past three days have provided an important opportunity for regulators from many countries to come together to strengthen the international peer review process,'' said U.S. NRC Chairman Gregory B. Jaczko. ''Especially after the Fukushima Daiichi accident, the global community recognizes that IRRS missions fill a vital role in strengthening nuclear safety and security programs around the world, and we are proud to be a part of this important effort.'' The IAEA Action Plan on Nuclear Safety includes actions focused towards strengthening the existing IAEA peer reviews, incorporating lessons learned and improving their effectiveness. The workshop provided a platform for the exchange of information, experience and lessons learned from the IRRS missions, as well as expectations for the IRRS programme for the near future. Further improvements in the planning and implementation of the IRRS missions in the longer term were discussed. A strong commitment of all relevant national authorities to the IRRS programme was identified as a key element of an effective regulatory framework. The conclusions of the workshop will be issued in November 2011 and the main results will be reported to the IAEA

    New regulations on the protection and rights of workers occupationally exposed to asbestos were introduced in Croatia in 2007 and 2008. They have been harmonised with the European Union (EU) and International Labour Organization (ILO) regulations, and make a step forward in safety at work, health protection, social rights, and pension schemes for Croatian workers occupationally exposed to asbestos. The 2007 Croatian regulation on the protection of workers from the risks related to exposure to asbestos at work defines and describes activities in which workers can be occupationally exposed to asbestos, defines the threshold value of asbestos in the air at work, defines valid methods for measurement of asbestos concentrations in the air, and establishes measures to reduce asbestos exposure at work or protect the exposed workers. Croatian law regulating obligatory health surveillance of workers occupationally exposed to asbestos from year 2007 defines activities and competent authorities to implement health surveillance of workers occupationally exposed to asbestos and to diagnose occupational diseases related to asbestos. This law also defines "occupational exposure to asbestos", and "occupational asbestos-related diseases", including asbestosis (pulmonary asbestos-related fibrosis), pleural asbestos-related disorders (plaques, pleural thickening, and benign effusion), lung and bronchial cancer, and malignant mesothelioma of serous membranes. These regulations have been harmonised with ILO, Directive 2003/18/EC amending Council Directive 83/477/EEC on the protection of workers from the risks related to exposure to asbestos at work, and with the Commission Recommendation 2003/670/EC concerning the European schedule of occupational diseases. The 2008 Croatian regulation on conditions of health surveillance, diagnostic procedures and criteria for confirmation of occupational asbestos-related diseases "defines the terms and the content of medical examination of workers

    In this report an international review of regulatory and industry practices is provided in the area of nuclear power plant staffing during the 1980s in Canada, France, Germany, Japan, Sweden, and the United Kingdom. The objective of this review is to highlight trends in staffing regulatory approaches, industry practices, and issues of concern in other countries that have potential relevance to nuclear power plant staffing issues in the United States. The decade of the 1980s was marked by a great deal of growth in nuclear power operations internationally; however, growth of nuclear power is not expected to continue in the 1990s except in France and Japan. A continuum of regulatory approaches to staffing was identified, ranging from prescribed regulations that are applied to all licensees (Germany is most similar to the United States in this regard), to indirect staffing regulations where the regulatory authority oversees plant operating practices that are agreed to in the plant operating license (most notably, France and the United Kingdom). Most of the changes observed in staffing regulations and practices in the early 1980s were made in response to the accident at the Three Mile Island Unit 2 nuclear power plant (TMI) in 1979. These changes included the widespread issuance of new operator and licensing requirements and the establishment of national training centers. After the post-TMI changes were implemented, a period of relative stability followed. Changes in the latter half of the 1980s have focused on continuing improvements and additions to training curricula and methods, most notably increased reliance on simulator training

    I would like to begin by thanking NRC Chairman Allison Macfarlane for hosting this first regulatory Conference on nuclear security involving regulators, law enforcement agencies and the IAEA. The United States has been a very important partner in the IAEA's nuclear security activities right from the start. It is by far the largest donor to our Nuclear Security Fund. It has actively supported our programmes and has been generous in providing funding, equipment and training to other Member States. When President Obama hosted the first Nuclear Security Summit in April 2010, he said it was important that that event should be part of a ''serious and sustained effort'' to improve nuclear security throughout the world. Since then, a growing number of governments have given high-level attention to this vitally important issue. This is very encouraging. Today, I am especially pleased to see regulators coming together to focus on this subject. I am confident that your meeting will make a valuable contribution to strengthening global nuclear security. I would like to share with you some important recent milestones in the IAEA's nuclear security work. As you know, primary responsibility for ensuring nuclear security lies with national governments. However, governments have recognized that international cooperation is vital. Terrorists and other criminals do not respect international borders and no country can respond effectively on its own to the threat which they pose. In September, our Member States - there are now 158 - reaffirmed the central role of the IAEA in e nsuring coordination of international activities in the field of nuclear security, while avoiding duplication and overlap . Our central role reflects the Agency's extensive membership, our mandate, our unique expertise and our long experience of providing technical assistance and specialist, practical guidance to countries. To put it simply, our work focuses on helping to minimize the risk of nuclear and other

    The International Health Regulations (IHR) 2005, as the overarching instrument for global health security, are designed to prevent and cope with major international public health threats. But poor implementation in countries hampers their effectiveness. In the wake of a number of major international health crises, such as the 2014 Ebola and 2016 Zika outbreaks, and the findings of a number of high-level assessments of the global response to these crises, it has become clear that there is a need for more joined-up thinking between health system strengthening activities and health security efforts for prevention, alert and response. WHO is working directly with its Member States to promote this approach, more specifically around how to better embed the IHR (2005) core capacities into the main health system functions. This paper looks at how and where the intersections between the IHR and the health system can be best leveraged towards developing greater health system resilience. This merging of approaches is a key component in pursuit of Universal Health Coverage and strengthened global health security as two mutually reinforcing agendas.

  14. Drilling in troubled waters. For an international regulation on offshore gas and oil activities

    International Nuclear Information System (INIS)

    Rochette, Julien

    2014-01-01

    Due to an increased energy demand, offshore activities are being extended to deep and ultra-deep waters: nearly one third of consumed oil and one quarter of consumed gas come from offshore drilling. This development threatens the environment and natural resources, and may have an impact on human activities which depend on the concerned ecosystems. As some accident had cross-border consequences, the relevance of the international regulatory framework is put into question again. This article first outlines the incomplete character of the legal framework for the safety of offshore activities: uncoordinated national systems, lack of an international convention, fragmented regional initiatives (some agreements exist for some specific regions: Arctic Sea, Baltic Sea, Mediterranean Sea, North-Eastern Atlantic, Persic Gulf and Oman Sea, Africa, western Indian Ocean). The author outlines that there is no international rules regarding responsibility and compensations. While highlighting the risks of a status-quo on these different issues, the author proposes and discusses a set of recommendations aimed at strengthening the regulation of offshore drilling activities

    Extended spectrum β-lactamase (ESBL)-positive Escherichia coli is a major etiological organism responsible for bovine mastitis. The autoinducer 2 (AI-2) quorum sensing system is widely present in many species of gram-negative and gram-positive bacteria and has been proposed to be involved in interspecies communication. In E. coli model strains, the functional mechanisms of AI-2 have been well studied; however, in clinical antibiotic-resistant E. coli strains, whether AI-2 affects the expression of antibiotic resistance genes has not been reported. In this study, we report that exogenous AI-2 increased the antibiotic resistance of a clinical E. coli strain isolated from a dairy cow with mastitis by upregulating the expression of TEM-type enzyme in an LsrR (LuxS regulated repressor)-dependent manner.

  17. International cooperation for the development of consistent and stable transportation regulations to promote and enhance safety and security

    International Nuclear Information System (INIS)

    Strosnider, J.

    2004-01-01

    International commerce of radioactive materials crosses national boundaries, linking separate regulatory institutions with a common purpose and making it necessary for these institutions to work together in order to achieve common safety goals in a manner that does not place an undue burden on industry and commerce. Widespread and increasing use of radioactive materials across the world has led to increases in the transport of radioactive materials. The demand for consistency in the oversight of international transport has also increased to prevent unnecessary delays and costs associated with incongruent or redundant regulatory requirements by the various countries through which radioactive material is transported. The International Atomic Energy Agency (IAEA) is the authority for international regulation of transportation of radioactive materials responsible for promulgation of regulations and guidance for the establishment of acceptable methods of transportation for the international community. As such, the IAEA is seen as the focal point for consensus building between its Member States to develop consistency in transportation regulations and reviews and to ensure the safe and secure transport of radioactive material. International cooperation is also needed to ensure stability in our regulatory processes. Changes to transportation regulations should be based on an anticipated safety benefit supported by risk information and insights gained from continuing experience, evaluation, and research studies. If we keep safety as the principle basis for regulatory changes, regulatory stability will be enhanced. Finally, as we endeavour to maintain consistency and stability in our international regulations, we must be mindful of the new security challenges that lay before the international community as a result of a changing terrorist environment. Terrorism is a problem of global concern that also requires international cooperation and support, as we look for ways to

    The One Health approach encompasses multiple themes and can be understood from many different perspectives. This paper expresses the viewpoint of those in charge of responding to public health events of international concern and, in particular, to outbreaks of zoonotic disease. Several international organisations are involved in responding to such outbreaks, including the United Nations (UN) and its technical agencies; principally, the Food and Agriculture Organization of the UN (FAO) and the World Health Organization (WHO); UN funds and programmes, such as the United Nations Development Programme, the World Food Programme, the United Nations Environment Programme, the United Nations Children's Fund; the UN-linked multilateral banking system (the World Bank and regional development banks); and partner organisations, such as the World Organisation for Animal Health (OIE). All of these organisations have benefited from the experiences gained during zoonotic disease outbreaks over the last decade, developing common approaches and mechanisms to foster good governance, promote policies that cut across different sectors, target investment more effectively and strengthen global and national capacities for dealing with emerging crises. Coordination among the various UN agencies and creating partnerships with related organisations have helped to improve disease surveillance in all countries, enabling more efficient detection of disease outbreaks and a faster response, greater transparency and stakeholder engagement and improved public health. The need to build more robust national public human and animal health systems, which are based on good governance and comply with the International Health Regulations (2005) and the international standards set by the OIE, prompted FAO, WHO and the OIE to join forces with the World Bank, to provide practical tools to help countries manage their zoonotic disease risks and develop adequate resources to prevent and control disease

    The aim of this article is to assess the role played by both individual and contextual factors in reducing the manager's levels of stress and strain within the workplace setting. This article also highlights the manager's locus of control (LOC) as an internal factor and emphasizes the social support variable as a contextual factor. We use a sample of 332 respondents belonging to Spanish manufacturing and services firms and a structural equation modeling technique (partial least squares path modeling). The results reveal that there are significant differences between managers and owners about stress-strain relationship. The study provides support for the literature on stress management, which emphasizes the importance of a LOC and social support in influencing stress and strain between managers and owners.

    Mechanical structure-property relations have been quantified for AISI 4140 steel. under different strain rates and temperatures. The structure-property relations were used. to calibrate a microstructure-based internal state variable plasticity-damage model for. monotonic tension, compression and torsion plasticity, as well as damage evolution. Strong stress state and temperature dependences were observed for the AISI 4140 steel. Tension tests on three different notched Bridgman specimens were undertaken to study. the damage-triaxiality dependence for model validation purposes. Fracture surface. analysis was performed using Scanning Electron Microscopy (SEM) to quantify the void. nucleation and void sizes in the different specimens. The stress-strain behavior exhibited. a fairly large applied stress state (tension, compression dependence, and torsion), a. moderate temperature dependence, and a relatively small strain rate dependence.

    The revised International Health Regulations [IHR(2005)], which requires the Member States of the World Health Organization (WHO) to develop core capacities to detect, assess, report, and respond to public health threats, is bringing new challenges for national and international surveillance systems. As more countries move toward implementation and/or strengthening of their infectious disease surveillance programs, the strengthening of clinical microbiology laboratories becomes increasingly important because they serve as the first line responders to detect new and emerging microbial threats, re-emerging infectious diseases, the spread of antibiotic resistance, and the possibility of bioterrorism. In fact, IHR(2005) Core Capacity #8, "Laboratory", requires that laboratory services be a part of every phase of alert and response.Public health laboratories in many resource-constrained countries require financial and technical assistance to build their capacity. In recognition of this, in 2006, the American Society for Microbiology (ASM) established an International Laboratory Capacity Building Program, LabCap, housed under the ASM International Board. ASM LabCap utilizes ASM's vast resources and its membership's expertise-40,000 microbiologists worldwide-to strengthen clinical and public health laboratory systems in low and low-middle income countries. ASM LabCap's program activities align with HR(2005) by building the capability of resource-constrained countries to develop quality-assured, laboratory-based information which is critical to disease surveillance and the rapid detection of disease outbreaks, whether they stem from natural, deliberate or accidental causes.ASM LabCap helps build laboratory capacity under a cooperative agreement with the U.S. Centers for Disease Control and Prevention (CDC) and under a sub-contract with the Program for Appropriate Technology in Health (PATH) funded by the United States Agency for International Development (USAID

    The role of the European Energy Regulators Group (ERGEG) in the realization of the internal energy market is discussed. It is concluded that the ERGEG has already achieved significant results in dealing with several complex technical and legal problems that hamper market integration in the energy sector. However, it is a fundamental problem that the ERGEG is neither an EU institution nor a national institution, resulting in a lack of its democratic accountability and in the legal protection against the actions taken by the ERGEG. Therefore, the future success of the ERGEG will depend on the ability of the European legislator to find answers to the question how to ensure that the ERGEG fulfils its tasks in a legitimate way [nl

    2009-11-01

    The regulation of khat, one of the most recent psychoactive drugs to become a globally traded commodity, remains hotly contested within different producer and consumer countries. As regimes vary, it has been possible to compare khat policies in Africa, Europe and North America from different disciplinary perspectives. Field research was conducted in East Africa and Europe, using a combination of semistructured interviews, participant observation and the analysis of trade statistics. The research established the significance of khat for rural producers, regional economies, as a tax base and source of foreign exchange. At the same time, khat as a psychoactive substance is associated with health and public safety problems that in turn are met with often ill-informed legislative responses. Bans have in turn lead to the criminalisation of users and sellers and illegal drug markets. The empirical work from Africa provides a strong argument for promoting evidence-based approaches to khat regulation, harnessing the positive aspects of the khat economy to develop a control model that incorporates the voices and respects the needs of rural producers. Ultimately, the framework for khat may provide both a model and an opportunity for revising the international treaties governing the control of other plant psychoactive-based substances.

    Cell and tissue-based products, such as autologous adult stem cells, are being prescribed by physicians across the world for diseases and illnesses that they have neither been approved for or been demonstrated as safe and effective in formal clinical trials. These doctors often form part of informal transnational networks that exploit differences and similarities in the regulatory systems across geographical contexts. In this paper, we examine the regulatory infrastructure of five geographically diverse but socio-economically comparable countries with the aim of identifying similarities and differences in how these products are regulated and governed within clinical contexts. We find that while there are many subtle technical differences in how these regulations are implemented, they are sufficiently similar that it is difficult to explain why these practices appear more prevalent in some countries and not in others. We conclude with suggestions for how international governance frameworks might be improved to discourage the exploitation of vulnerable patient populations while enabling innovation in the clinical application of cellular therapies.

    Abstract Objective To respond to the World Health Assembly call for dissemination of lessons learnt from countries that have begun implementing the International Health Regulations, 2005 revision; IHR (2005). Methods In November 2015, we conducted a systematic search of the following online databases and sources: PubMed®, Embase®, Global Health, Scopus, World Health Organization (WHO) Global Index Medicus, WHO Bulletin on IHR Implementation and the International Society for Disease Surveillance. We included identified studies and reports summarizing national experience in implementing any of the IHR (2005) core capacities or their components. We excluded studies that were theoretical or referred to IHR (1969). Qualitative systematic review methodology, including meta-ethnography, was used for qualitative synthesis. Findings We analysed 51 articles from 77 countries representing all WHO Regions. The meta-syntheses identified a total of 44 lessons learnt across the eight core capacities of IHR (2005). Major themes included the need to mobilize and sustain political commitment; to adapt global requirements based on local sociocultural, epidemiological, health system and economic contexts; and to conduct baseline and follow-up assessments to monitor the status of IHR (2005) implementation. Conclusion Although experiences of IHR (2005) implementation covered a wide global range, more documentation from Africa and Eastern Europe is needed. We did not find specific areas of weakness in monitoring IHR (2005); sustained monitoring of all core capacities is required to ensure effective systems. These lessons learnt could be adapted by countries in the process of meeting IHR (2005) requirements. PMID:29403114

    2012-01-01

    Background Traditional top-down national regulation of internationally mobile doctors and nurses is fast being rendered obsolete by the speed of globalisation and digitisation. Here we propose a bottom-up system in which responsibility for hiring and accrediting overseas staff begins to be shared by medical employers, managers, and insurers. Discussion In this model, professional Boards would retain authority for disciplinary proceedings in response to local complaints, but would lose their present power of veto over foreign practitioners recruited by employers who have independently evaluated and approved such candidates' ability. Evaluations of this kind could be facilitated by globally accessible National Registers of professional work and conduct. A decentralised system of this kind could also dispense with time-consuming national oversight of continuing professional education and license revalidation, which tasks could be replaced over time by tighter institutional audit supported by stronger powers to terminate underperforming employees. Summary Market forces based on the reputation (and, hence, financial and political viability) of employers and institutions could continue to ensure patient safety in the future, while at the same time improving both national system efficiency and international professional mobility.

    Endothelin-1 (ET-1) and ET-3 mRNA have been found in the pancreas. We investigated the ability of ET-1, ET-2, and ET-3 to interact with and alter dispersed rat pancreatic acinar cell function. Radiolabeled ETs bound in a time- and temperature-dependent fashion, which was specific and saturable. Analysis demonstrated two classes of receptors, one class (ETA receptor) had a high affinity for ET-1 but a low affinity for ET-3, and the other class (ETB receptor) had equally high affinities for ET-1 and ET-3. No specific receptor for ET-2 was identified. Pancreatic secretagogues that activate phospholipase C (PLC) inhibited binding of 125I-labeled ET-1 (125I-ET-1) or 125I-ET-3, whereas agents that act through adenosine 3',5'-cyclic monophosphate (cAMP) did not. A23187 had no effect on 125I-ET-1 or 125I-ET-3 binding, whereas the phorbol ester 12-O-tetradecanoylphorbol 13-acetate reduced binding. The effect of cholecystokinin octapeptide (CCK-8) was mediated through its own receptor. Stripping of surface bound ligand studies demonstrated that both 125I-labeled ET-1 and 125I-labeled ET-3 were rapidly internalized. CCK-8 decreased the internalization but did not change the amount of surface bound ligand. Endothelins neither stimulate nor alter changes in enzyme secretion, intracellular calcium, cAMP, or [3H]inositol trisphosphate (IP3). This study demonstrates the presence of ETA and ETB receptors on rat pancreatic acini; occupation of both receptors resulted in rapid internalization, which is regulated by PLC-activating secretagogues. Occupation of either ET receptor did not alter intracellular calcium, cAMP, IP3, or stimulate amylase release.

Regulations embody the public expectations for how buildings and facilities are expected to perform and as such represent public policy. Regulators, who develop and enforce regulations, are empowered to act in the public's interest to set this policy and are ultimately responsible to the public in this regard. Standardization contributes to the basic infrastructure that underpins society including health and environment, while promoting sustainability and good regulatory practice. The international organizations that produce International Standards are the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO), and the International Telecommunication Union (ITU). With the increasing globalization of markets, International Standards (as opposed to regional or national standards) have become critical to the trading process, ensuring a level playing field for exports, and ensuring that imports meet the internationally recognized levels of performance and safety. The development of standards is done in response to sectors and stakeholders that express a clearly established need for them. An industry sector or other stakeholder group typically communicates its requirement for standards to one of the national members. To be accepted for development, a proposed work item must receive a majority support of the participating members, who verify the global relevance of the proposed item. The regulatory authority (RA) should provide a method for the recognition of international voluntary standards and for public notification of such recognition. The process of recognition may vary from country to country. Recognition may occur by periodic publication of lists of standards that a regulatory authority has found will meet the Essential Principles. In conclusion, International standards

    Full Text Available The present study investigates the nature of the link between the staphylococcal enterotoxin A (SEA gene and the lifecycle of Siphoviridae bacteriophages, including the origin of strain variation regarding SEA production after prophage induction. Five strains representing three different genetic lines of the sea region were studied under optimal and prophage-induced growth conditions and the Siphoviridae lifecycle was followed through the phage replicative form copies and transcripts of the lysogenic repressor, cro. The role of SOS response on prophage induction was addressed through recA transcription in a recA-disruption mutant. Prophage induction was found to increase the abundance of the phage replicative form, the sea gene copies and transcripts and enhance SEA production. Sequence analysis of the sea regions revealed that observed strain variances were related to strain capacity for prophage induction, rather than sequence differences in the sea region. The impact of SOS response activation on the phage lifecycle was demonstrated by the absence of phage replicative form copies in the recA-disruption mutant after prophage induction. From this study it emerges that all aspects of SEA-producing strain, the Siphoviridae phage and the food environment must be considered when evaluating SEA-related hazards.

    Acute and reproductive toxicity tests were conducted on seven strains of Daphnia magna from six laboratories in five countries. 3,4-Dichloroaniline (DCA) and fenoxycarb were used as test chemicals. Acute toxicity tests revealed that estimated EC50 (50% effective concentration) values for DCA varied...... by a factor of 2.1 among strains (310-640 mu g/L), whereas the EC50 values for fenoxycarb varied by a factor of 4 (210-860 mu g/L). EC50 values for reproductive toxicity tests with DCA ranged from 5.9 to 38 mu g/L among strains. Fenoxycarb exposure induced the production of male neonates in all the strains...... used in the present study. Estimated EC50 values for the induction of male offspring were highly variable among strains: sensitivity to fenoxycarb differed by a factor of approximately 23 overall (0.45-10 mu g/L). The present pre-validation tests suggest that induction of male sex in neonates...

    The reasonable regulations in USA consist of a graduated approach and a risk informed approach (RIA). RIA rationalizes the regulations on the basis of data of operations etc. PSA (Probabilistic Safety Assessment), a general method of RIA, is explained in detail. The benefits of nuclear power plant using RIA are increase of the rate of operation, visualization of risk, application of design standard and design, cost down of nuclear fuel cycle, waste, production and operation, and safety. RIA is supported by the field data, code, standard, regulation and professional engineers. The effects of introduction of RIA are explained. In order to introduce RIA in Japan, all the parties concerned such as the regulation authorities, the electric power industries, makers, universities, have to understand it and work together. A part of scientific society is stated. (S.Y.)

    Thailand conducted a national laboratory assessment of core capacities related to the International Health Regulations (IHR) (2005), and thereby established a baseline to measure future progress. The assessment was limited to public laboratories found within the Thai Bureau of Quality and Safety of Food, National Institute of Health and regional medical science centres. The World Health Organization (WHO) laboratory assessment tool was adapted to Thailand through a participatory approach. This adapted version employed a specific scoring matrix and comprised 16 modules with a quantitative output. Two teams jointly performed the on-site assessments in December 2010 over a two-week period, in 17 public health laboratories in Thailand. The assessment focused on the capacity to identify and accurately detect pathogens mentioned in Annex 2 of the IHR (2005) in a timely manner, as well as other public health priority pathogens for Thailand. Performance of quality management, budget and finance, data management and communications was considered strong (>90%); premises quality, specimen collection, biosafety, public health functions, supplies management and equipment availability were judged as very good (>70% but ≤90%); while microbiological capacity, staffing, training and supervision, and information technology needed improvement (>60% but ≤70%). This assessment is a major step in Thailand towards development of an optimized and standardized national laboratory network for the detection and reporting of infectious disease that would be compliant with IHR (2005). The participatory strategy employed to adapt an international tool to the Thai context can also serve as a model for use by other countries in the Region. The participatory approach probably ensured better quality and ownership of the results, while providing critical information to help decision-makers determine where best to invest finite resources.

    This study aimed at investigating the regulatory system of bacteriocin synthesis by Lactobacillus plantarum strains in vegetables and fruits in a model system. Sterile and neutralized cell-free supernatant (CFS) from L. plantarum strains grown in MRS broth showed in vitro antimicrobial activities toward various indicator strains. The highest activity was that of L. plantarum C2. The antimicrobial activity was further assayed on vegetable and fruit agar plates (solid conditions) and in juices (liquid conditions). A regulatory mechanism of bacteriocin synthesis via quorum sensing was hypothesized. The synthesis of antimicrobial compounds seemed to be constitutive under solid conditions of growth on vegetable and fruit agar plates. In contrast, it depended on the size of the inoculum when L. plantarum C2 was grown in carrot juice. Only the inoculum of ca. 9.0 log CFU ml−1 produced detectable activity. The genes plnA, plnEF, plnG, and plnH were found in all L. plantarum strains. The genes plnJK and plnN were detected in only three or four strains. Reverse-phase high-performance liquid chromatography purification and mass spectrometry analysis revealed the presence of a mixture of eight peptides in the most active fraction of the CFS from L. plantarum C2. Active peptides were encrypted into bacteriocin precursors, such as plantaricins PlnJ/K and PlnH and PlnG, which are involved in the ABC transport system. A real-time PCR assay showed an increase in the expression of plnJK and plnG during growth of L. plantarum C2 in carrot juice. PMID:24242246

  1. Recent international regulations: low dose-low rate radiation protection and the demise of reason.

    Okkalides, Demetrios

    2008-01-01

    The radiation protection measures suggested by the International Committee for Radiation Protection (ICRP), national regulating bodies and experts, have been becoming ever more strict despite the decrease of any information supporting the existence of the Linear no Threshold model (LNT) and of any adverse effects of Low Dose Low Rate (LDLR) irradiation. This tendency arises from the disproportionate response of human society to hazards that are currently in fashion and is unreasonable. The 1 mSv/year dose limit for the public suggested by the ICRP corresponds to a 1/18,181 detriment-adjusted cancer risk and is much lower than other hazards that are faced by modern societies such as e.g. driving and smoking which carry corresponding rate risks of 1/2,100 and 1/2,000. Even worldwide deadly work accidents rate is higher at 1/ 8,065. Such excessive safety measures against minimal risks from man made radiation sources divert resources from very real and much greater hazards. In addition they undermine research and development of radiation technology and tend to subjugate science and the quest for understanding nature to phobic practices.

  2. The didactic gesture of internal regulation in the ‘genres didactic sequence’

    Full Text Available This article brings results of a doctoral research based in the studies of Sociodiscursive Interactionism (SDI, particularly, in its didactic aspect. Data was obtained in a field research carried out in a public school of Londrina, Paraná State, in a 6th grade class, focused in the didactic transposition of the genre ‘letter of complaint’, under the instrumentalization of the ‘genre didactic sequence’ (GDS procedure. The epistemological focus of the article concentrates on the analysis of a founder didactic gesture: ‘the internal regulation’ –implemented by the diagnostic evaluation of the students initial production. The objective is to show the accomplishment of this gesture in the development of this step of the SDG, highlighting both the result of the learning diagnostic process and the specific didactic gestures mobilized to set this stage of the learning project. It was found that the didactic approach of the diagnostic regulation mobilized after the writing of the first version of the genre, is essential for the GDS global development, since it shows the ‘errors’ that require the didactic intervention.

  3. Regulated and unregulated emissions from an internal combustion engine operating on ethanol-containing fuels

    Poulopoulos, S. G.; Samaras, D. P.; Philippopoulos, C. J.

    In the present work, the effect of ethanol addition to gasoline on regulated and unregulated emissions is studied. A 4-cylinder OPEL 1.6 L internal combustion engine equipped with a hydraulic brake dynamometer was used in all the experiments. For exhaust emissions treatment a typical three-way catalyst was used. Among the various compounds detected in exhaust emissions, the following ones were monitored at engine and catalyst outlet: methane, hexane, ethylene, acetaldehyde, acetone, benzene, 1,3-butadiene, toluene, acetic acid and ethanol. Addition of ethanol in the fuel up to 10% w/w had as a result an increase in the Reid vapour pressure of the fuel, which indicates indirectly increased evaporative emissions, while carbon monoxide tailpipe emissions were decreased. For ethanol-containing fuels, acetaldehyde emissions were appreciably increased (up to 100%), especially for fuel containing 3% w/w ethanol. In contrast, aromatics emissions were decreased by ethanol addition to gasoline. Methane and ethanol were the most resistant compounds to oxidation while ethylene was the most degradable compound over the catalyst. Ethylene, methane and acetaldehyde were the main compounds present at engine exhaust while methane, acetaldehyde and ethanol were the main compounds in tailpipe emissions for ethanol fuels after the catalyst operation.

  4. Space Science and the International Traffic in Arms Regulations: Summary of a Workshop

    2008-01-01

    The United States seeks to protect its security and foreign-policy interests, in part, by actively controlling the export of goods, technologies, and services that are or may be useful for military development in other nations. "Export" is defined not simply as the sending abroad of hardware but also as the communication of related technology and know-how to foreigners in the United States and overseas. The U.S. government mechanism for controlling dual-use items--items in commerce that have potential military use is the Export Administration Regulations (EAR) administered by the Department of Commerce; items defined in law as defense articles fall under the jurisdiction of the Department of State and the International Traffic in Arms Regulations (ITAR). Because of the potential military implications of the export of defense articles, the ITAR regime imposes much greater burdens (on both the applicant and the government) than does the EAR regime during the process of applying for, and implementing the provisions of, licenses and technical-assistance agreements. Until the early 1990s export control activity related to all space satellites (commercial and scientific) was handled under ITAR. Between 1992 and 1996 the George H.W. Bush and the Clinton administrations transferred jurisdiction over the licensing of civilian communications satellites to the Commerce Department under EAR. In 1999, however, in response to broad concerns about Chinese attempts to acquire U.S. high technology, the U.S. House of Representatives convened the Select Committee on U.S. National Security and Military/Commercial Concerns with the People s Republic of China, also known as the Cox Committee. One of the many consequences of the Cox Committee's report was Congress's mandate that jurisdiction over export and licensing of satellites and related equipment and services, irrespective of military utility, be transferred from the Department of Commerce to the State Department and that such

    The work activity developed on board is of great importance in our nearby environment, and it has a series of peculiarities that determine the service rendering of sea workers. On the other hand, work at sea is developed on an international basis. Nowadays such work becomes a completely globalised industrial sector in relation to the elements that make up the ship's operation, including manpower. For that reason several relevant international organisations have paid attention to this industrial sector and have adopted a broad regulation on this matter. In the case of the European Union, the Community procedure emphasises enormous interest in providing specific and comprehensive training to seafarers, as well as in regulating working time on board with the aim of minimising the safety problems caused by fatigue. In the present article a schematic presentation of regulations on workers' health and occupational safety protection derived from the European Union, the International Maritime Organisation, and the International Labour Organisation has been done. Also it shows what parts of these regulations are not applicable to the work on board, and it reveals how the workers of fishing and maritime transport sectors are under-protected with regard to the guarantee of their health and occupational safety compared to workers in other sectors.

  12. The Acinetobacter baumannii Two-Component System AdeRS Regulates Genes Required for Multidrug Efflux, Biofilm Formation, and Virulence in a Strain-Specific Manner

    Directory of Open Access Journals (Sweden)

    Grace E. Richmond

    2016-04-01

    Full Text Available The opportunistic pathogen Acinetobacter baumannii is able to persist in the environment and is often multidrug resistant (MDR, causing difficulties in the treatment of infections. Here, we show that the two-component system AdeRS, which regulates the production of the AdeABC multidrug resistance efflux pump, is required for the formation of a protective biofilm in an ex vivo porcine mucosal model, which mimics a natural infection of the human epithelium. Interestingly, deletion of adeB impacted only on the ability of strain AYE to form a biofilm on plastic and only on the virulence of strain Singapore 1 for Galleria mellonella. RNA-Seq revealed that loss of AdeRS or AdeB significantly altered the transcriptional landscape, resulting in the changed expression of many genes, notably those associated with antimicrobial resistance and virulence interactions. For example, A. baumannii lacking AdeRS displayed decreased expression of adeABC, pil genes, com genes, and a pgaC-like gene, whereas loss of AdeB resulted in increased expression of pil and com genes and decreased expression of ferric acinetobactin transport system genes. These data define the scope of AdeRS-mediated regulation, show that changes in the production of AdeABC mediate important phenotypes controlled by AdeRS, and suggest that AdeABC is a viable target for antimicrobial drug and antibiofilm discovery.

    Child maltreatment is a robust risk factor for internalizing and externalizing psychopathology in children and adolescents. We examined the role of disruptions in emotion regulation processes as a developmental mechanism linking child maltreatment to the onset of multiple forms of psychopathology in adolescents. Specifically, we examined whether child maltreatment was associated with emotional reactivity and maladaptive cognitive and behavioral responses to distress, including rumination and impulsive behaviors, in two separate samples. We additionally investigated whether each of these components of emotion regulation were associated with internalizing and externalizing psychopathology and mediated the association between child maltreatment and psychopathology. Study 1 included a sample of 167 adolescents recruited based on exposure to physical, sexual, or emotional abuse. Study 2 included a sample of 439 adolescents in a community-based cohort study followed prospectively for 5 years. In both samples, child maltreatment was associated with higher levels of internalizing psychopathology, elevated emotional reactivity, and greater habitual engagement in rumination and impulsive responses to distress. In Study 2, emotional reactivity and maladaptive responses to distress mediated the association between child maltreatment and both internalizing and externalizing psychopathology. These findings provide converging evidence for the role of emotion regulation deficits as a transdiagnostic developmental pathway linking child maltreatment with multiple forms of psychopathology.

    Nunamycin and nunapeptin are two antimicrobial cyclic lipopeptides (CLPs) produced by Pseudomonas fluorescens In5 and synthesized by nonribosomal synthetases (NRPS) located on two gene clusters designated the nun-nup regulon. Organization of the regulon is similar to clusters found in other CLP-producing pseudomonads except for the border regions where putative LuxR-type regulators are located. This study focuses on understanding the regulatory role of the LuxR-type-encoding gene nunF in CLP production of P. fluorescens In5. Functional analysis of nunF coupled with liquid chromatography-high-resolution mass spectrometry (LC-HRMS) showed that CLP biosynthesis is regulated by nunF. Quantitative real-time PCR analysis indicated that transcription of the NRPS genes catalyzing CLP production is strongly reduced when nunF is mutated indicating that nunF is part of the nun-nup regulon. Swarming and biofilm formation was reduced in a nunF knockout mutant suggesting that these CLPs may also play a role in these phenomena as observed in other pseudomonads. Fusion of the nunF promoter region to mCherry showed that nunF is strongly upregulated in response to carbon sources indicating the presence of a fungus suggesting that environmental elicitors may also influence nunF expression which upon activation regulates nunamycin and nunapeptin production required for the growth inhibition of phytopathogens. © 2017 The Authors.

  20. Child Maltreatment, Inflammation, and Internalizing Symptoms: Investigating the Roles of C-Reactive Protein, Gene Variation and Neuroendocrine Regulation

    Science.gov (United States)

    Cicchetti, Dante; Handley, Elizabeth D.; Rogosch, Fred A.

    2015-01-01

    Prior research has found inconsistent evidence regarding the association among childhood adversity, inflammation, and internalizing symptoms, perhaps because previous studies have yet to adequately integrate important factors such as the timing of the adversity, genetic variation, and other relevant processes such as neuroendocrine regulation. The aims of the present study were threefold: 1) Determine whether the effect of the timing of child maltreatment on C-reactive protein (CRP), an inflammatory marker, varies by CRP gene variation; 2) Explore whether links between salivary CRP and childhood internalizing symptoms depend on the presence and timing of maltreatment experiences; 3) Investigate the role of CRP in the relations between child neuroendocrine regulation and internalizing symptoms and examine whether these associations are moderated by the presence and timing of child maltreatment. Participants included a sample of 267 maltreated and 222 nonmaltreated children (M age= 9.72, SD=0.99; 52.4% male; 66% African-American) who attended a summer day camp research program designed for school-aged low-income children. Department of Human Services records were examined to determine the onset and recency of maltreatment for children in the maltreated group. Results indicated that among children with recent onset maltreatment, those with at least one A allele from CRP SNP rs1417938 evidenced significantly higher CRP levels compared to recently maltreated children carrying the TT genotype. Moreover, higher levels of CRP were associated with higher levels of internalizing symptoms only for recently maltreated children. Finally, we did not find support for salivary CRP as a mechanism in the relation between neuroendocrine regulation and childhood internalizing symptoms. Our findings highlight the importance of the timing of child maltreatment and have important implications for characterizing variability in inflammation and internalizing symptoms among youth. PMID

    In general, governmental regulation of insurance activity in construction area is implemented in such forms as: the formation of the legal framework, the implementation of insurance supervision and control, the registration and licensing of the insurance. The regulation of the insurance sector is diverse in its nature. Processes of the regulation of the insurance business have to consider a number of diverse interests of both insurers and insurance holders. The effectiveness of the regulation depends on the fullness of consideration of long-term market factors.

    Eggs are a major source of human infections with Salmonella. Therefore controlling egg contamination in laying hen flocks is one of the main targets for control programmes. A study was carried out to assess the effect of oral vaccination with TAD Salmonella vac E, TAD Salmonella vac T and with both vaccines TAD Salmonella vac E and TAD Salmonella vac T, on colonization of the reproductive tract and internal egg contamination of laying hens with Salmonella Enteritidis. Three groups of 30 laying hens were vaccinated at 1 day, 6 weeks and 16 weeks of age with either one of the vaccine strains, or a combination of both vaccine strains, while a fourth group was left unvaccinated. At 24 weeks of age, the birds were intravenously challenged with 0.5 ml containing 5 x 10(7)cfu Salmonella Enteritidis PT4 S1400/94. The number of oviducts from which Salmonella was isolated, was significantly lower in the vaccinated than in the non-vaccinated hens at 3 weeks post-challenge. Significantly less egg contents were Salmonella positive in the birds vaccinated with TAD Salmonella vac E or TAD Salmonella vac T (12/105 batches of eggs in both groups) than in the unvaccinated birds (28/105 batches of eggs). Internal egg contamination in the hens vaccinated with both TAD Salmonella vac E and TAD Salmonella vac T was even more reduced, as over the whole experiment, only one batch of eggs was positive. In conclusion, these data indicate that vaccination of laying hens with these live vaccines could be considered as a valuable tool in controlling internal egg contamination.

Although there is no international regulation or legislation specifically for nanomedicine, it is agreed worldwide that considerably more attention should be paid to the quality, safety, and efficacy of nanotechnology-based drugs. The US Food and Drug Administration and the European Medicines Agency have provided several draft regulatory guidance and reflection papers to assist the development of nanomedicines. To cope with the impact of nanotechnology and to foster its pharmaceutical applications and development in Taiwan, this article reviews the trends of regulating nanotechnology-based pharmaceuticals in the international community and proposes strategies for Taiwan’s regulation harmonized with international considerations. The draft regulatory measures include a chemistry, manufacturing, and controls (CMC review checklist and guidance for CMC review of liposomal products. These have been submitted for discussion among an expert committee, with membership comprised of multidisciplinary academia, research institutions, the pharmaceutical industry, and regulators, and are currently approaching final consensus.

    The somatostatin receptor 2 (sst2) is the pharmacological target of somatostatin analogs that are widely used in the diagnosis and treatment of human neuroendocrine tumors. We have recently shown that the stable somatostatin analogs octreotide and pasireotide (SOM230) stimulate distinct patterns of sst2 receptor phosphorylation and internalization. Like somatostatin, octreotide promotes the phosphorylation of at least six carboxyl-terminal serine and threonine residues namely S341, S343, T353, T354, T356 and T359, which in turn leads to a robust receptor endocytosis. Unlike somatostatin, pasireotide stimulates a selective phosphorylation of S341 and S343 of the human sst2 receptor followed by a partial receptor internalization. Here, we show that exchange of S341 and S343 by alanine is sufficient to block pasireotide-driven internalization, whereas mutation of T353, T354, T356 and T359 to alanine is required to strongly inhibited both octreotide- and somatostatin-induced internalization. Yet, combined mutation of T353, T354, T356 and T359 is not sufficient to prevent somatostatin-driven β-arrestin mobilization and receptor desensitization. Replacement of all fourteen carboxyl-terminal serine and threonine residues by alanine completely abrogates sst2 receptor internalization and β-arrestin mobilization in HEK293 cells. Together, our findings demonstrate for the first time that agonist-selective sst2 receptor internalization is regulated by multi-site phosphorylation of its carboxyl-terminal tail.

    Glyphosate is a widely used herbicide that inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) activity. Most plants and microbes are sensitive to glyphosate. However, transgenic-resistant crops that contain a modified epsps obtained from the resistant microbes have been commercially successful and therefore, new resistance genes and their adaptive regulatory mechanisms are of great interest. In this study, a soil-borne, glyphosate-resistant bacterium was selected and identified as Enterobacter. The EPSPS in this strain was found to have been altered to a resistant one. A total of 42 differentially expressed genes (DEGs) in the glyphosate were screened using microarray techniques. Under treatment, argF, sdhA, ivbL, rrfA-H were downregulated, whereas the transcripts of speA, osmY, pflB, ahpC, fusA, deoA, uxaC, rpoD and a few ribosomal protein genes were upregulated. Data were verified by quantitative real-time PCR on selected genes. All transcriptional changes appeared to protect the bacteria from glyphosate and associated osmotic, acidic and oxidative stresses. Many DEGs may have the potential to confer resistance to glyphosate alone, and some may be closely related to the shikimate pathway, reflecting the complex gene interaction network for glyphosate resistance. © 2013 Federation of European Microbiological Societies.

    Plant-growth promotion has been linked to the Pseudomonas genus since the beginning of this research field. In this work, we mined the genome of an Argentinean isolate of the recently described species P. donghuensis. Strain SVBP6, isolated from bulk soil of an agricultural plot, showed a broad antifungal activity and several other plant-probiotic activities. As this species has been recently described, and it seems like some plant-growth promoting (PGP) traits do not belong to the classical pseudomonads toolbox, we decide to explore the SVBP6 genome via an bioinformatic approach. Genome inspection confirmed our previous in vitro results about genes involved in several probiotic activities. Other genetic traits possibly involved in survival of SVBP6 in highly competitive environments, such as rhizospheres, were found. Tn5 mutagenesis revealed that the antifungal activity against the soil pathogen Macrophomina phaseolina was dependent on a functional gacS gene, from the regulatory cascade Gac-Rsm, but it was not due to volatile compounds. Altogether, our genomic analyses and in vitro tests allowed the phylogenetic assignment and provided the first insights into probiotic properties of the first P. donghuensis isolate from the Americas.

    Full Text Available In the development of international relations, hostage-taking was carried out as an insurance against fraud, not keeping obligations, or according to the rules of war law. Earlier taking hostages was more related to armed conflicts, and in modern times it is more related to terrorist acts in international terrorism. The taking of hostages is an international offense, which has its essential elements and characteristics. It is a crime punishable under the national legislation of many countries, and taking of hostages in armed conflicts is a war crime for which the International Criminal Court is responsible. International terrorism is manifested through a variety of terrorist acts, which, through fear and panic aim to achieve a political purpose. The range of these terrorist acts is wide and varied. One of these terrorist activities is the taking of hostages. As an offense established by the norms of international law, this unlawful act must be specifically investigated and clarified, which is the goal of this paper. This paper gives an overview of the features and elements of the offense in the light of international law and the laws of the Republic of Serbia.

    This document examines the optimal environmental regulation of three Norwegian power projects, energy conservation, a natural gas fired combined cycle gas turbine and a new hydro project. All projects reduce emissions elsewhere in the Nordic region, and in general the environmental costs of these emissions are not optimally reflected in market prices. A theory of second best optimal regulation is developed for this case. The optimal regulation is found to deviate considerably from a purely domestic regulation. For instance, it is found optimal to grant a substantial credit to energy conservation. The credit is sensitive to the value of reduced CO{sub 2} emissions and whether the current Norwegian end user tax should be interpreted as an environmental or a fiscal tax. 27 refs., 4 tabs.

    . Moreover, internalized EGFRvIII is recycled rather than delivered to lysosomes. EGFRvIII binds the ubiquitin ligase c-Cbl via Grb2, whereas binding via phosphorylated tyrosine residue 1045 seems to be limited. Despite c-Cbl binding, the receptor fails to become effectively ubiquitinylated. Thus, our...... results suggest that the long lifetime of EGFRvIII is caused by inefficient internalization and impaired sorting to lysosomes due to lack of effective ubiquitinylation....

  14. Characterisation of Australian MRSA strains ST75- and ST883-MRSA-IV and analysis of their accessory gene regulator locus.

    Directory of Open Access Journals (Sweden)

    Stefan Monecke

    Full Text Available BACKGROUND: Community-acquired methicillin-resistant Staphylococcus aureus have become a major problem in Australia. These strains have now been isolated throughout Australia including remote Indigenous communities that have had minimal exposure to healthcare facilities. Some of these strains, belonging to sequence types ST75 and ST883, have previously been reported to harbour highly divergent alleles of the housekeeping genes used in multilocus sequence typing. METHODOLOGY/PRINCIPAL FINDINGS: ST75-MRSA-IV and ST883-MRSA-IV isolates were characterised in detail. Morphological features as well as 16S sequences were identical to other S. aureus strains. Although a partial rnpB gene sequence was not identical to previously known S. aureus sequences, it was found to be more closely related to S. aureus than to other staphylococci. Isolates also were screened using diagnostic DNA microarrays. These isolates yielded hybridisation results atypical for S. aureus. Primer directed amplification assays failed to detect species markers (femA, katA, sbi, spa. However, arbitrarily primed amplification indicated the presence of unknown alleles of these genes. Isolates could not be assigned to capsule types 1, 5 or 8. The allelic group of the accessory gene regulator (agr locus was not determinable. Sequencing of a region of agrB, agrC and agrD (approximately 2,100 bp revealed a divergent sequence. However, this sequence is more related to S. aureus agr alleles I and IV than to agr sequences from other Staphylococcus species. The predicted auto-inducing peptide (AIP sequence of ST75 was identical to that of agr group I, while the predicted AIP sequence of ST883 was identical to agr group IV. CONCLUSIONS/SIGNIFICANCE: The genetic properties of ST75/ST883-MRSA may be due to a series of evolutionary events in ancient insulated S. aureus strains including a convergent evolution leading to agr group I- or IV-like AIP sequences and a recent acquisition of SCCmec IV

    As an international legal instrument, the International Health Regulations (IHR) is internationally binding in 196 countries, especially in all the member states of the World Health Organization (WHO). The IHR aims to prevent, protect against, control, and respond to the international spread of disease and aims to cut out unnecessary interruptions to traffic and trade. To meet IHR requirements, countries need to improve capacity construction by developing, strengthening, and maintaining core response capacities for public health risk and Public Health Emergency of International Concern (PHEIC). In addition, all the related core capacity requirements should be met before June 15, 2012. If not, then the deadline can be extended until 2016 upon request by countries. China has promoted the implementation of the IHR comprehensively, continuingly strengthening the core public health capacity and advancing in core public health emergency capacity building, points of entry capacity building, as well as risk prevention and control of biological events (infectious diseases, zoonotic diseases, and food safety), radiological, nuclear, and chemical events, and other catastrophic events. With significant progress in core capacity building, China has dealt with many public health emergencies successfully, ensuring that its core public health capacity has met the IHR requirements, which was reported to WHO in June 2014. This article describes the steps, measures, and related experiences in the implementation of IHR in China. PMID:26029897

    2017-08-01

    Full Text Available Enterotoxigenic Escherichia coli (ETEC is the most common bacterial cause of diarrhea in children in developing countries, as well as in travelers to these countries. To cause disease, ETEC needs to produce a series of virulence proteins including enterotoxins, colonization factors and secretion pathways, which enable this pathogen to colonize the human small intestine and deliver enterotoxins to epithelial cells. Previously, a number of studies have demonstrated that CfaD, an AraC-like transcriptional regulator, plays a key role in virulence gene expression by ETEC. In this study, we carried out a transcriptomic analysis of ETEC strain, H10407, grown under different conditions, and determined the complete set of genes that are regulated by CfaD. In this way, we identified a number of new target genes, including rnr-1, rnr-2, etpBAC, agn43, flu, traM and ETEC_3214, whose expression is strongly activated by CfaD. Using promoter-lacZ reporters, primer extension and electrophoretic mobility shift assays, we characterized the CfaD-mediated activation of several selected target promoters. We also showed that the gut-associated environmental signal, sodium bicarbonate, stimulates CfaD-mediated upregulation of its virulence target operons. Finally, we screened a commercial small molecule library and identified a compound (CH-1 that specifically inhibited the regulatory function of CfaD, and by 2-D analoging, we identified a second inhibitor (CH-2 with greater potency.

  19. Radioactive waste sea disposal practices and the need for international regulations

    International Nuclear Information System (INIS)

    Reyners, P.

    1975-01-01

    Radioactive waste is mainly disposed of as liquid releases in coastal waters or as solid wastes dumped in the high seas. The Geneva Convention on the high seas which lays down that Contracting States should not, by unilateral measures, pollute the seas by dumping radioactive wastes, and Article 37 of the Euratom Treaty on the Commission's control over radioactive waste disposal plans by Member States constitute the principal legal basis for such activities at international level. The competent international organisations, IAEA and the OECD Nuclear Energy Agency (NEA), have both made detailed studies on the scientific, technical and legal aspects of sea disposal of radioactive wastes. Following consideration of the possibilities of waste dumping in the Atlantic and the related hazard assessment, at its Member State's request, NEA in 1967 undertook an initial experimental packaged waste disposal operation in the high seas. This operation's technical success encouraged Member States to undertake further operations in subsequent years under NEA international control. At present, in view of the entry into force of the London Convention on prevention of marine pollution by dumping of wastes, it seems desirable that the international character of such operations be preserved and all countries concerned be encouraged to adopt an international code of practice for sea disposal of radioactive wastes [fr

    E-cadherin internalization facilitates dissolution of adherens junctions and promotes tumor cell epithelial-mesenchymal transition (EMT) and migration. Our previous results have shown that Arf6 exerts pro-migratory action in breast cancer cells after EGF stimulation. Despite the fact that EGF signaling stimulates EMT of breast cancer cells, the effect of Arf6 on internalization of E-cadherin of breast cancer cells under EGF treatment remains to be determined. Here, we showed that EGF dose-dependently stimulated E-cadherin internalization by MCF-7 cells with the maximal effect at 50 ng/ml. Meanwhile, EGF treatment markedly increased Arf6 activation. Arf6 was involved in complexes of E-cadherin, and more E-cadherin was pulled down with Arf6 when the activity of the latter was increased. Immunoblotting and immunofluorescence assays showed that transfection breast cancer cells with Arf6-T27N or Arf6 siRNA suppressed EGF-induced E-cadherin internalization. Taken together, our study demonstrated that Arf6 activation plays a potential role in EGF-induced E-cadherin internalization, providing new mechanism underlying the effect of Arf6 on promoting breast cancer cell metastasis.

  2. Molecular approaches to understand the regulation of N2O emission from denitrifying bacteria - model strains and soil communities (Invited)

    Science.gov (United States)

    Frostegard, A.; Bakken, L. R.

    2010-12-01

    Emissions of N2O from agricultural soils are largely caused by denitrifying bacteria. Field measurements of N2O fluxes show large variations and depend on several environmental factors, and possibly also on the composition of the denitrifying microbial community. The temporal and spatial variation of fluxes are not adequately captured by biogeochemical models, and few options for mitigations have been invented, which underscores the need to understand the mechanisms underlying the emissions of N2O. Analyses of denitrification genes and transcripts extracted from soils are important for describing the system, but may have limited value for prediction of N2O emissions. In contrast, phenotypic analyses are direct measures of the organisms’ responses to changing environmental conditions. Our approach is to combine phenotypic characterizations using high-resolution gas kinetics, with gene transcription analyses to study denitrification regulatory phenotypes (DRP) of bacterial strains or complex microbial communities. The rich data sets obtained provide a basis for refinement of biochemical and physiological research on this key process in the nitrogen cycle. The strength of this combined approach is illustrated by a series of experiments investigating effects of soil pH on denitrification. Soil pH emerges as a master variable determining the microbial community composition as well as its denitrification product ratio (N2O/N2), with higher ratio in acid than in alkaline soil. It is therefore likely that emissions of N2O from agro-ecosystems will increase in large parts of the world where soil pH is decreasing due to intensified management and increased use of chemical fertilizers. Considering its immense implications, surprisingly few attempts have been made to unravel the mechanisms involved in the pH-control of the product stoichiometry of denitrification. We investigated the kinetics of gas transformations (O2, NO, N2O and N2) and transcription of functional genes

  4. Flavivirus internalization is regulated by a size-dependent endocytic pathway.

    Science.gov (United States)

    Hackett, Brent A; Cherry, Sara

    2018-04-17

    Flaviviruses enter host cells through the process of clathrin-mediated endocytosis, and the spectrum of host factors required for this process are incompletely understood. Here we found that lymphocyte antigen 6 locus E (LY6E) promotes the internalization of multiple flaviviruses, including West Nile virus, Zika virus, and dengue virus. Perhaps surprisingly, LY6E is dispensable for the internalization of the endogenous cargo transferrin, which is also dependent on clathrin-mediated endocytosis for uptake. Since viruses are substantially larger than transferrin, we reasoned that LY6E may be required for uptake of larger cargoes and tested this using transferrin-coated beads of similar size as flaviviruses. LY6E was indeed required for the internalization of transferrin-coated beads, suggesting that LY6E is selectively required for large cargo. Cell biological studies found that LY6E forms tubules upon viral infection and bead internalization, and we found that tubule formation was dependent on RNASEK, which is also required for flavivirus internalization, but not transferrin uptake. Indeed, we found that RNASEK is also required for the internalization of transferrin-coated beads, suggesting it functions upstream of LY6E. These LY6E tubules resembled microtubules, and we found that microtubule assembly was required for their formation and flavivirus uptake. Since microtubule end-binding proteins link microtubules to downstream activities, we screened the three end-binding proteins and found that EB3 promotes virus uptake and LY6E tubularization. Taken together, these results highlight a specialized pathway required for the uptake of large clathrin-dependent endocytosis cargoes, including flaviviruses. Copyright © 2018 the Author(s).

    Clostridium botulinum is a heat-resistant spore-forming bacterium that causes the serious paralytic illness botulism. Heat-resistant spores may cause food sanitation hazards and sporulation plays a central role in the survival of C. botulinum. We observed morphological changes and investigated the role of the transcriptional regulator SpoIIID in the sporulation of C. botulinum type B strain 111 in order to elucidate the molecular mechanism in C. botulinum. C. botulinum type B formed heat-resistant spores through successive morphological changes corresponding to those of Bacillus subtilis, a spore-forming model organism. An analysis of the spoIIID gene knockout mutant revealed that the transcriptional regulator SpoIIID contributed to heat-resistant spore formation by C. botulinum type B and activated the transcription of the sigK gene later during sporulation. Transcription of the spoIIID gene, which differed from that in B. subtilis and Clostridium difficile, was observed in the sigE gene knockout mutant of C. botulinum type B. An analysis of the sigF gene knockout mutant showed that the sporulation-specific sigma factor SigF was essential for transcription of the spoIIID gene in C. botulinum type B. These results suggest that the regulation of sporulation in C. botulinum is not similar to that in B. subtilis and other clostridia. Copyright © 2015 Elsevier Ltd. All rights reserved.

  16. Safety at sea: oil spills, the tanker business and international regulations

    Energy Technology Data Exchange (ETDEWEB)

    Golomer, Olivier

    1994-02-01

    The tanker industry has been assailed in recent years with regulations, inspections, and many, many criticisms. The official objective of these pressures - the preservation of the environment from oil spills and oil contamination - is praiseworthy. However, many of these measures have proved inefficient or have led to ludicrous situations due in large part to them being targeted on crisis situations. Instead of emergency regulations spurred by sporadic disasters, both the tanker industry and protection of the environment need a set of economic instruments relying on a systematic assessment of risks. This paper focuses on these issues in the Very Large Crude Carrier segment of the tanker business. We start with a description of the industry and the actors in place, and then review the measures and policies adopted so far and their influence on the industry, especially in relation to freight rates. By analogy with other industries, a comprehensive approach to environmental hazards is then proposed. (Author)

    2014-01-01

    Full Text Available The emergence and expansion of the recent financial crisis has renewed the question of regulation and supervision of the financial system. Therefore, the question of managing financial risks is becoming increasingly popular and gaining more and more importance. Regulators have in recent years introduced capital standards based on specific sensitivity to risk. Based on defined issues, the starting point is the general hypothesis that the capital adequacy is a key base for measuring the resistance of the banking and insurance sector to market shocks. This paper will present the analytical, synthetic and general scientific methods. The comparative method is used in this paper to highlight the similarities and differences between Solvency II and Basel III and their operational efficiency.

  20. Internal cholinergic regulation of learning and recall in a model of olfactory processing

    Directory of Open Access Journals (Sweden)

    Licurgo Benemann Almeida

    2016-11-01

    Full Text Available In the olfactory system, cholinergic modulation has been associated with contrast modulation and changes in receptive fields in the olfactory bulb, as well the learning of odor associations in olfactory cortex. Computational modeling and behavioral studies suggest that cholinergic modulation could improve sensory processing and learning while preventing pro-active interference when task demands are high. However, how sensory inputs and/or learning regulate incoming modulation has not yet been elucidated. We here use a computational model of the olfactory bulb, piriform cortex (PC and horizontal limb of the diagonal band of Broca (HDB to explore how olfactory learning could regulate cholinergic inputs to the system in a closed feedback loop. In our model, the novelty of an odor is reflected in firing rates and sparseness of cortical neurons in response to that odor and these firing rates can directly regulate learning in the system by modifying cholinergic inputs to the system. In the model, cholinergic neurons reduce their firing in response to familiar odors – reducing plasticity in the PC, but increase their firing in response to novel odor – increasing PC plasticity. Recordings from HDB neurons in awake behaving rats reflect predictions from the model by showing that a subset of neurons decrease their firing as an odor becomes familiar.

    2008-01-01

    Integrating reduced emissions from deforestation and degradation (REDD) into a post-Kyoto intergovernmental carbon market could significantly decrease global carbon prices and the costs of mitigating climate change. We investigate this impact by simulating the impact of the supply of REDD units on the international carbon market in 2020 under unlimited and restricted exchange conditions. We find restricting supply or demand of REDD credits reduces such price impacts, but comes at the cost of ...

    Child labor is a persistent phenomenon in many developing countries. In recent years, support has been growing among rich-country governments and consumer groups for the use of trade policies, such as product boycotts and the imposition of international labor standards, to reduce child labor in poor countries. In this paper, we discuss research on the long-run implications of such policies. In particular, we demonstrate that such measures may have the unintended side effect of lowering domest...

  3. Arrestin scaffolds NHERF1 to the P2Y12 receptor to regulate receptor internalization.

    2012-07-13

    We have recently shown in a patient with mild bleeding that the PDZ-binding motif of the platelet G protein-coupled P2Y(12) receptor (P2Y(12)R) is required for effective receptor traffic in human platelets. In this study we show for the first time that the PDZ motif-binding protein NHERF1 exerts a major role in potentiating G protein-coupled receptor (GPCR) internalization. NHERF1 interacts with the C-tail of the P2Y(12)R and unlike many other GPCRs, NHERF1 interaction is required for effective P2Y(12)R internalization. In vitro and prior to agonist stimulation P2Y(12)R/NHERF1 interaction requires the intact PDZ binding motif of this receptor. Interestingly on receptor stimulation NHERF1 no longer interacts directly with the receptor but instead binds to the receptor via the endocytic scaffolding protein arrestin. These findings suggest a novel model by which arrestin can serve as an adaptor to promote NHERF1 interaction with a GPCR to facilitate effective NHERF1-dependent receptor internalization.

    2016-01-01

    The NEA provides an effective forum for international co-operation on nuclear safety and regulatory issues in its specific task groups, working parties and expert groups, as well as through joint international safety research projects. In these activities, NEA member countries work together to share and analyse data and experiences, gain consensus and develop approaches that can be applied within each country’s governmental processes. Through effective international co-operation, NEA member countries have worked together to develop actions for improving their regulatory frameworks and nuclear installation safety. As a result of these efforts, safety improvements and further harmonisation have been realized in the areas operating reactors, new reactors, human and organisational factors and nuclear safety research. At the NEA, technical and programmatic work under the Committee on Nuclear Regulatory Activities (CNRA), the Committee on the Safety of Nuclear Installations (CSNI), joint safety research projects and the Multinational Design Evaluation Programme (MDEP) have helped NEA member countries to ensure a high standard for nuclear safety and to further develop the technical knowledge base.

    Pasechnyk, Olena V; Hendel, Nataliia V

    2018-01-01

    Introduction: The development of international legal cooperation in the field of health has largely been driven by the trade interests of states. The aim: The article analyzes the legal regulation of the circulation of medicines through the prism of the law of the World Trade Organization. Materials and methods: Using the historical legal method has allowed to analyze the genesis of legal regulation of the circulation of medicines through the prism of the law of the World Trade Organization. The dialectical method is widely used, in particular, when it comes to the issue of the ratio of market regulation of medicines circulation and public health protection, the formal logic method, in particular, in formulating the general principles, principles and methods of legal regulation in the field of medicines, as well as the systemic method, in particular, in defining the institutional component of legal regulation in the field of medicines. Review: The activities of the WTO include several areas related to health protection: international control over infectious diseases, international legal regulation of food safety (food security), tobacco control, environmental protection, international legal aspects of access and treatment of medicinal and pharmaceutical products, international legal regulation of medical services provision. Conclusions: It is proved that the right to health is a right to access to medicines. However, for many developing countries, it is problematic to obtain patents for the production of necessary medicines or to pay a license fee, which creates a barrier to the realization of the right to health.

    Full Text Available The interplay of neural and hormonal mechanisms activated by entero- and exteroreceptors biases the selection of actions by decision making neuronal circuits. The reproductive behaviour of acoustically communicating grasshoppers, which is regulated by short-term neural and longer-term hormonal mechanisms, has frequently been used to study the cellular and physiological processes that select particular actions from the species-specific repertoire of behaviours. Various grasshoppers communicate with species- and situation-specific songs in order to attract and court mating partners, to signal reproductive readiness or to fend off competitors. Selection and coordination of type, intensity and timing of sound signals is mediated by the central complex, a highly structured brain neuropil known to integrate multimodal pre-processed sensory information by a large number of chemical messengers. In addition, reproductive activity including sound production critically depends on maturation, previous mating experience and oviposition cycles. In this regard, juvenile hormone released from the corpora allata has been identified as a decisive hormonal signal necessary to establish reproductive motivation in grasshopper females. Both regulatory systems, the central complex mediating short-term regulation and the corpora allata mediating longer-term regulation of reproduction related sound production mutually influence each other’s activity in order to generate a coherent state of excitation that promotes or suppresses reproductive behaviour in respective appropriate or inappropriate situations.This review summarizes our current knowledge about extrinsic and intrinsic factors that influence grasshopper reproductive motivation, their representation in the nervous system and their integrative processing that mediates the initiation or suppression of reproductive behaviors.

    Numerous strains of Aspergillus oryzae are industrially used for Japanese traditional fermentation and for the production of enzymes and heterologous proteins. In A. oryzae, deletion of the ku70 or ligD genes involved in non-homologous end joining (NHEJ) has allowed high gene targeting efficiency. However, this strategy has been mainly applied under the genetic background of the A. oryzae wild strain RIB40, and it would be laborious to delete the NHEJ genes in many A. oryzae industrial strains, probably due to their low gene targeting efficiency. In the present study, we generated ligD mutants from the A. oryzae industrial strains by employing the CRISPR/Cas9 system, which we previously developed as a genome editing method. Uridine/uracil auxotrophic strains were generated by deletion of the pyrG gene, which was subsequently used as a selective marker. We examined the gene targeting efficiency with the ecdR gene, of which deletion was reported to induce sclerotia formation under the genetic background of the strain RIB40. As expected, the deletion efficiencies were high, around 60~80%, in the ligD mutants of industrial strains. Intriguingly, the effects of the ecdR deletion on sclerotia formation varied depending on the strains, and we found sclerotia-like structures under the background of the industrial strains, which have never been reported to form sclerotia. The present study demonstrates that introducing ligD mutation by genome editing is an effective method allowing high gene targeting efficiency in A. oryzae industrial strains.

    European requirements for radiological protection, especially work on transposing the new EURATOM Directive on the basic radiological protection standards, are currently being revised. The Direction generale du travail (DGT - General Directorate of Labour) and the Autorite de Surete Nucleaire (ASN - Nuclear Safety Authority) therefore commissioned the Radiological Protection Standing Groups of experts (GPRAD and GPMED)1 to engage in a forward-looking debate on the delimitation of and access to regulated areas, within an ad hoc working group (called hereafter 'Classification of Area WG'). To fuel its debates, the 'Classification of Area WG' sought elements on international regulations and practices focusing on problem exposure situations in various areas of activity (nuclear, industrial, research, medical, transport and natural boosted). CEPN was entrusted with this study. This report presents a summary of rules applicable in seven countries in terms of delimitation of and access to regulated radiological protection areas. The countries are: Belgium, Spain, United States, Finland, United Kingdom, Sweden and Switzerland. Detailed sheets for each country can be found in the Annex. Based on these summaries, three countries have been selected to apply their rules and practices in force to a dozen or so particular cases put together by the 'Classification of Area WG' that are representative of exposure situations. The three countries are Finland, United Kingdom and Switzerland. The case studies applied to each country are presented in the second part of this report

    2013-01-01

    The role of the post-transcriptional carbon storage regulator (Csr) system in nutrient utilization and in the control of the central metabolism in E. coli reference commensal strain Nissle 1917 was investigated. Analysis of the growth capabilities of mutants altered for various components of the Csr system (csrA51, csrB, csrC and csrD mutations) showed that only the protein CsrA - the key component of the system - exerts a marked role in carbon nutrition. Attenuation of CsrA activity in the csrA51 mutant affects the growth efficiency on a broad range of physiologically relevant carbon sources, including compounds utilized by the Entner-Doudoroff (ED) pathway. Detailed investigations of the metabolomes and fluxomes of mutants and wild-type cells grown on carbon sources representative of glycolysis and of the ED pathway (glucose and gluconate, respectively), revealed significant re-adjusting of central carbon metabolism for both compounds in the csrA51 mutant. However, the metabolic re-adjusting observed on gluconate was strikingly different from that observed on glucose, indicating a nutrient-specific control of metabolism by the Csr system.

    Obtain baseline information on the status of the basic capacities of the health sector at the local, municipal, and provincial levels in order to facilitate identification of priorities and guide public policies that aim to comply with the requirements and capacities established in Annex 1A of the International Health Regulations 2005 (IHR-2005). A descriptive cross-sectional study was conducted by application of an instrument of evaluation of basic capacities referring to legal and institutional autonomy, the surveillance and research process, and the response to health emergencies in 36 entities involved in international sanitary control at the local, municipal, and provincial levels in the provinces of Havana, Cienfuegos, and Santiago de Cuba. The polyclinics and provincial centers of health and epidemiology in the three provinces had more than 75% of the basic capacities required. Twelve out of 36 units had implemented 50% of the legal and institutional framework. There was variable availability of routine surveillance and research, whereas the entities in Havana had more than 40% of the basic capacities in the area of events response. The provinces evaluated have integrated the basic capacities that will allow implementation of IHR-2005 within the period established by the World Health Organization. It is necessary to develop and establish effective action plans to consolidate surveillance as an essential activity of national and international security in terms of public health.

  19. International recommendations on scope of radiological protection regulations - ICRP Publication 104

    2011-01-01

    The system of radiological protection applies, in principle, to all exposures to ionising radiation. Nevertheless, in practice, the measures taken in order to control these exposures should be limited for pragmatic reasons. ICRP Publication 104 deals with the scope of radiological protection control measures and describes the instruments that can be used for this purpose: exclusion, exemption, clearance. This paper aims to present the ICRP recommendations on scope of regulations in all types of exposure situations: planned, emergency and existing. Also, there are discussed the instruments available to regulators in different exposure situations. Exclusion refers to the deliberate omission of exposure situations from the scope of regulatory requirements, and exemption refers to waiving regulatory requirements if their application is not warranted. A special case of exemption, termed 'clearance', refers to the relinquishing of regulatory control if such a control becomes unwarranted. Societal attitudes to the control of exposure situations are taken into account in determining what can be excluded or exempted from regulatory control. People have higher demands for controlling 'artificial' exposure situations than for dealing with 'natural' exposure situations. Therefore, account should be taken not only of the justification and optimisation of controlling measures, but also of the different expectations of those affected by the exposure situations. The recommendations in this report are intended to assist in defining what needs to be the subject of regulatory requirements for radiological protection and what does not. The application of regulatory controls should achieve a net benefit in protection; otherwise, regulatory control is not justified. Similarly, regulatory requirements should be applied in a manner that optimises protection, otherwise the application of regulatory requirements is not warranted. (authors)

  1. Regulation

    International Nuclear Information System (INIS)

    Ballereau, P.

    1999-01-01

    The different regulations relative to nuclear energy since the first of January 1999 are given here. Two points deserve to be noticed: the decree of the third august 1999 authorizing the national Agency for the radioactive waste management to install and exploit on the commune of Bures (Meuse) an underground laboratory destined to study the deep geological formations where could be stored the radioactive waste. The second point is about the uranium residues and the waste notion. The judgment of the administrative tribunal of Limoges ( 9. july 1998) forbidding the exploitation of a storage installation of depleted uranium considered as final waste and qualifying it as an industrial waste storage facility has been annulled bu the Court of Appeal. It stipulated that, according to the law number 75663 of the 15. july 1965, no criteria below can be applied to depleted uranium: production residue (possibility of an ulterior enrichment), abandonment of a personal property or simple intention to do it ( future use aimed in the authorization request made in the Prefecture). This judgment has devoted the primacy of the waste notion on this one of final waste. (N.C.)

    Full Text Available The subject of the study is the socio-economic aspects of the social responsibility of business (CSR in 4 countries. The purpose of the article is to study the experience in regulating the socio-economic responsibility of entrepreneurship in the United States, Sweden, India, and China to determine the direction of formation of the state mechanism of socio-economic responsibility of entrepreneurship (SERE in Ukraine. The methodology of the article became theoretical researches of foreign scientists, their synthesis, systematization, and analysis for the development of the application of experience in Ukrainian realities. The analysis showed how different states of CSR policy differ in each of these countries and made it possible to draw conclusions about the application in Ukraine. So, the experience of Sweden is useful in reviewing the social reporting obligation, as well as the experience of China. In the case of the USA, the role of the state in regulating CSRs in enterprises should be noted but, at the same time, the significant social consciousness of American entrepreneurs as recognized philanthropists, who are actively introducing ethical codes and key stewards from the implementation of CSR, are seen by society and aimed at improving the well-being of society. In China, the government plays an important role in the implementation of CSR for state-owned enterprises. In addition, laws are adopted to improve the rights of employees, to equalize gender differences, to increase the level of production, quality of products, which leads to an improvement in the quality of life of the country’s population. All this becomes relevant for Ukraine and can be used in our country as well. Indian experience draws attention through the adoption of a unique decision on the indifference of charity activities by Indian companies with a certain level of profit and the adoption of them by the rules of corporate social responsibility.

    Global effort and initiatives undertaken after the Fukushima Daiichi accident was the adoption of the Vienna Declaration on Nuclear Safety in February 2015. The Contracting Parties to the Convention on Nuclear Safety (CNS) collaboratively prepared the documentation of the Declaration and unanimously adopted it with the idea to prevent accidents with radiological consequences and to mitigate such consequences should they occur. The OECD/NEA has been working closely with its member and partner countries to identify lessons learnt and follow-up actions at the national and international levels so as to maintain and enhance the level of safety at nuclear facilities following the Fukushima Daiichi nuclear power plant accident. In 2013, the NEA published a report entitled The Fukushima Daiichi Nuclear Power Plant Accident: OECD/NEA Nuclear Safety Response and Lessons Learnt detailing the key immediate responses of the NEA and its member countries. Subsequent to the publish of the report and based on the lessons presented, NEA published a new report entitled Five Years after the Fukushima Daiichi Accident: Nuclear Safety Improvements and Lessons Learnt, focusing on what has been done by the Agency and its member countries to improve safety since the accident in 2011. cooperation based on the needs of technical area would further enhance effectiveness of cooperative activities and would enable to foresee future regulatory needs which can be considered when establishing a strategy. Since the establishment of NSSC in 2011, NSSC has played a major role in concluding agreements with regulatory bodies of other countries. Despite of the change, KINS, yet, is able to pursue technical-specified cooperation as a TSO under the umbrella of agreements between governments or regulatory bodies. establishment of expert pool and systematic mid- and long-term capacity building framework of relevant experts would enhance continuity and expertise.

    As reviewed by [Cooper, S. J. (2008). From Claude Bernard to Walter Cannon: emergence of the concept of homeostasis. Appetite 51, 419-27.] Claude Bernard's idea of stabilisation of bodily states, as realised in Walter B. Cannon's conception of homeostasis, took mathematical form during the 1940s in the principle that externally originating disturbance of a physiological parameter can feed an informative signal around the brain to trigger counteractive processes--a corrective mechanism known as negative feedback, in practice reliant on feedforward. Three decades later, enough was known of the physiology and psychology of eating and drinking for calculations to show how experimentally demonstrated mechanisms of feedforward that had been learnt from negative feedback combine to regulate exchanges of water and energy between the body and the surroundings. Subsequent systemic physiology, molecular neuroscience and experimental psychology, however, have been traduced by a misconception that learnt controls of intake are 'non-homeostatic', the myth of biological 'set points' and an historic failure to address evidence for the ingestion-adapting information-processing mechanisms on which an operationally integrative theory of eating and drinking relies.

    Full Text Available The current labour market has many forms of employment relations that differ from full-time employment. "Atypical," "non-standard," or even "marginal" are terms used to describe these new workers and include, amongst others, part-time work, contract work, self-employment, temporary, fixed-term, seasonal, casual, piece-rate work, employees supplied by employment agencies, home workers and those employed in the informal economy. These workers are often paid for results rather than time. Their vulnerability is linked in many instances to the absence of an employment relationship or the existence of a flimsy one. Most of these workers are unskilled or work in sectors with limited trade union organisation and limited coverage by collective bargaining, leaving them vulnerable to exploitation. They should, in theory, have the protection of current South African labour legislation, but in practice the unusual circumstances of their employment render the enforcement of their rights problematic. The majority of non-standard workers in South Africa are those previously disadvantaged by the apartheid regime, compromising women and unskilled black workers. The exclusion of these workers from labour legislation can be seen as discrimination, which is prohibited by almost all labour legislation in South Africa. This contribution illustrates how the concept of indirect discrimination can be an important tool used to provide labour protection to these workers. The purpose of this article is to explore the scope of the extension of labour rights to non-standard workers in the context of South African labour laws and the international framework.

    Full Text Available Mesenchymal stromal cells (MSCs are multipotent cells with abilities to exert immunosuppressive response promoting tissue repair. Studies have shown that MSCs can secrete extracellular vesicles (MVs-MSCs with similar regulatory functions to the parental cells. Furthermore, strong evidence suggesting that MVs-MSCs can modulate several immune cells (i.e., Th1, Th17, and Foxp3+ T cells. However, their precise effect on macrophages (Mϕs remains unexplored. We investigated the immunoregulatory effect of MVs-MSCs on activated M1-Mϕs in vitro and in vivo using differentiated bone marrow Mϕs and an acute experimental model of thioglycollate-induced peritonitis, respectively. We observed that MVs-MSCs shared surface molecules with MSCs (CD44, CD105, CD90, CD73 and expressed classical microvesicle markers (Annexin V and CD9. The in vitro treatment with MVs-MSCs exerted a regulatory-like phenotype in M1-Mϕs, which showed higher CD206 level and reduced CCR7 expression. This was associated with decreased levels of inflammatory molecules (IL-1β, IL-6, nitric oxide and increased immunoregulatory markers (IL-10 and Arginase in M1-Mϕs. In addition, we detected that MVs-MSCs promoted the downregulation of inflammatory miRNAs (miR-155 and miR-21, as well as, upregulated its predicted target gene SOCS3 in activated M1-Mϕs. In vivo MVs-MSCs treatment reduced the Mϕs infiltrate in the peritoneal cavity inducing a M2-like regulatory phenotype in peritoneal Mϕs (higher arginase activity and reduced expression of CD86, iNOS, IFN-γ, IL-1β, TNF-α, IL-1α, and IL-6 molecules. This in vivo immunomodulatory effect of MVs-MSCs on M1-Mϕs was partially associated with the upregulation of CX3CR1 in F4/80+/Ly6C+/CCR2+ Mϕs subsets. In summary, our findings indicate that MVs-MSCs can modulate an internal program in activated Mϕs establishing an alternative regulatory-like phenotype.

    Full Text Available This paper centers on some whole-istic organizational and functional aspects of hepatic Schistosoma mansoni granuloma, which is an extremely complex system. First, it structurally develops a collagenic topology, originated bidirectionally from an inward and outward assembly of growth units. Inward growth appears to be originated from myofibroblasts derived from small portal vessel around intravascular entrapped eggs, while outward growth arises from hepatic stellate cells. The auto-assembly of the growth units defines the three-dimensional scaffold of the schistosome granulomas. The granuloma surface irregularity and its border presented fractal dimension equal to 1.58. Second, it is internally regulated by intricate networks of immuneneuroendocrine stimuli orchestrated by leptin and leptin receptors, substance P and Vasoactive intestinal peptide. Third, it can reach the population of ± 40,000 cells and presents an autopoietic component evidenced by internal proliferation (Ki-67+ Cells, and by expression of c-Kit+ Cells, leptin and leptin receptor (Ob-R, granulocyte-colony stimulating factor (G-CSF-R, and erythropoietin (Epo-R receptors. Fourth, the granulomas cells are intimately connected by pan-cadherins, occludin and connexin-43, building a state of closing (granuloma closure. In conclusion, the granuloma is characterized by transitory stages in such a way that its organized structure emerges as a global property which is greater than the sum of actions of its individual cells and extracellular matrix components.

    Full Text Available Abstract Background Regulating synthesis of the Fragile X gene (FMR1 product, FMRP alters neural plasticity potentially through its role in the microRNA pathway. Cap-dependent translation of the FMR1 mRNA, a process requiring ribosomal scanning through the 5' leader, is likely impeded by the extensive secondary structure generated by the high guanosine/cytosine nucleotide content including the CGG triplet nucleotide repeats in the 5' leader. An alternative mechanism to initiate translation – internal initiation often utilizes secondary structure to recruit the translational machinery. Consequently, studies were undertaken to confirm and extend a previous observation that the FMR1 5' leader contains an internal ribosomal entry site (IRES. Results Cellular transfection of a dicistronic DNA construct containing the FMR1 5' leader inserted into the intercistronic region yielded significant translation of the second cistron, but the FMR1 5' leader was also found to contain a cryptic promoter possibly confounding interpretation of these results. However, transfection of dicistronic and monocistronic RNA ex vivo or in vitro confirmed that the FMR1 5' leader contains an IRES. Moreover, inhibiting cap-dependent translation ex vivo did not affect the expression level of endogenous FMRP indicating a role for IRES-dependent translation of FMR1 mRNA. Analysis of the FMR1 5' leader revealed that the CGG repeats and the 5' end of the leader were vital for internal initiation. Functionally, exposure to potassium chloride or intracellular acidification and addition of polyinosinic:polycytidylic acid as mimics of neural activity and double stranded RNA, respectively, differentially affected FMR1 IRES activity. Conclusion Our results indicate that multiple stimuli influence IRES-dependent translation of the FMR1 mRNA and suggest a functional role for the CGG nucleotide repeats.

    South Africa has an extensive mining industry, with total mineral sales in 2002 being R140 billion and total mineral exports being R110 billion. In this same year, the industry employed over 400 000 workers. When the International Atomic Energy Agency Regulations for the Safe Transport of Radioactive Material (TS-R-1 [ST-1 Revised]) (the Regulations), was adopted by the regulatory body, the National Nuclear Regulator (NNR), in June 2001, the Industry requested the drafting of a guide on the interpretation of these regulations for NORM. This paper has arisen from the drafting of such a guide, drafted with the end-user in mind, giving an interpretation of the application of the Regulations to NORM. The paper is more ''Qualitative'' than ''Quantitative'' and raises a number of ''peculiar'' aspects of the application of the Regulations to NORM

    Epstein-Barr virus (EBV) is a ubiquitous pathogen of humans that can cause several types of lymphoma and carcinoma. Like other herpesviruses, EBV has diversified through both coevolution with its host and genetic exchange between virus strains. Sequence analysis of the EBV genome is unusually challenging because of the large number and lengths of repeat regions within the virus. Here we describe the sequence assembly and analysis of the large internal repeat 1 of EBV (IR1; also known as the BamW repeats) for more than 70 strains. The diversity of the latency protein EBV nuclear antigen leader protein (EBNA-LP) resides predominantly within the exons downstream of IR1. The integrity of the putative BWRF1 open reading frame (ORF) is retained in over 80% of strains, and deletions truncating IR1 always spare BWRF1. Conserved regions include the IR1 latency promoter (Wp) and one zone upstream of and two within BWRF1. IR1 is heterogeneous in 70% of strains, and this heterogeneity arises from sequence exchange between strains as well as from spontaneous mutation, with interstrain recombination being more common in tumor-derived viruses. This genetic exchange often incorporates regions of Epstein-Barr virus (EBV) infects the majority of the world population but causes illness in only a small minority of people. Nevertheless, over 1% of cancers worldwide are attributable to EBV. Recent sequencing projects investigating virus diversity to see if different strains have different disease impacts have excluded regions of repeating sequence, as they are more technically challenging. Here we analyze the sequence of the largest repeat in EBV (IR1). We first characterized the variations in protein sequences encoded across IR1. In studying variations within the repeat of each strain, we identified a mutation in the main laboratory strain of EBV that impairs virus function, and we suggest that tumor-associated viruses may be more likely to contain DNA mixed from two strains.

    1989-01-01

    The International Atomic Energy Agencies (IAEA) Regulations for the Safe Transport of Radioactive Material, Safety Series No.6 (hereinafter denoted as the Regulations) have developed into the model for international modal organization and individual country regulations (and other regulatory-related documentation) controlling the packaging and transportation of radioactive materials. The Regulations were initially developed in 1961 and have been periodically revised since then. Revised editions of the Regulations, accounting for developments in technology and shipping practices, were issued in 1965, 1967, 1973 (also, an amended 1973 Edition was issued in 1979), and in 1985. The process of developing these documents has been performed on a cooperative basis utilizing inputs from various member states of the IAEA and from other interested international organizations. The latest comprehensive revision of the Regulations and its supportive documents was initiated in 1979, and culminated in the 1985 Edition of the Regulations. This was the first complete revision to be published since 1973 (except for the amended Edition thereto being issued in 1979). During the process which led to the 1985 Edition of the Regulations and its supportive documents, it became apparent that changes needed to be made in this process. Not addressing issues related to transportation regulations on a continuing basis created many difficulties in trying to efficiently and acceptably review and revise these documents in a short period of time. The purpose of this paper is to outline the review/revision process which was established, to summarize the results from that process so far (in terms of changes that have been made to the 1985 Edition through supplements thereto), and to discuss current plans for carrying on with the review/revision process with slight modifications

    Full Text Available Abstract Foodborne salmonellosis is one of the most important bacterial zoonotic diseases worldwide. Salmonella Typhimurium is the serovar most frequently isolated from persistently infected slaughter pigs in Europe. Circumvention of the host’s immune system by Salmonella might contribute to persistent infection of pigs. In the present study, we found that Salmonella Typhimurium strain 112910a specifically downregulated MHC II, but not MHC I, expression on porcine alveolar macrophages in a Salmonella pathogenicity island (SPI-1 and SPI-2 dependent way. Salmonella induced downregulation of MHC II expression and intracellular proliferation of Salmonella in macrophages were significantly impaired after opsonization with Salmonella specific antibodies prior to inoculation. Furthermore, the capacity to downregulate MHC II expression on macrophages differed significantly among Salmonella strains, independently of strain specific differences in invasion capacity, Salmonella induced cytotoxicity and altered macrophage activation status. The fact that strain specific differences in MHC II downregulation did not correlate with the extent of in vitro SPI-1 or SPI-2 gene expression indicates that other factors are involved in MHC II downregulation as well. Since Salmonella strain dependent interference with the pig’s immune response through downregulation of MHC II expression might indicate that certain Salmonella strains are more likely to escape serological detection, our findings are of major interest for Salmonella monitoring programs primarily based on serology.

    If the Ebola tragedy of West Africa has taught us anything, it should be that the 2005 International Health Regulations (IHR) Treaty, which gave unprecedented authority to the World Health Organization (WHO) to provide global public health security during public health emergencies of international concern, has fallen severely short of its original goal. After encouraging successes with the 2003 severe acute respiratory syndrome (SARS) pandemic, the intent of the legally binding Treaty to improve the capacity of all countries to detect, assess, notify, and respond to public health threats has shamefully lapsed. Despite the granting of 2-year extensions in 2012 to countries to meet core surveillance and response requirements, less than 20% of countries have complied. Today it is not realistic to expect that these gaps will be solved or narrowed in the foreseeable future by the IHR or the WHO alone under current provisions. The unfortunate failures that culminated in an inadequate response to the Ebola epidemic in West Africa are multifactorial, including funding, staffing, and poor leadership decisions, but all are reversible. A rush by the Global Health Security Agenda partners to fill critical gaps in administrative and operational areas has been crucial in the short term, but questions remain as to the real priorities of the G20 as time elapses and critical gaps in public health protections and infrastructure take precedence over the economic and security needs of the developed world. The response from the Global Outbreak Alert and Response Network and foreign medical teams to Ebola proved indispensable to global health security, but both deserve stronger strategic capacity support and institutional status under the WHO leadership granted by the IHR Treaty. Treaties are the most successful means the world has in preventing, preparing for, and controlling epidemics in an increasingly globalized world. Other options are not sustainable.

    We examined resource allocation priorities in the framework of an updated Maslow hierarchy of fundamental human needs. In Experiment 1, the participants in the food abundance priming condition viewing photos of high-calorie food allocated more money to savings than to spending. However, the participants preferred spending to savings under the condition of mating availability priming with romantic photographs. In Experiment 2, before and after drinking either water or a sugary beverage, fasting participants rated photos of a conversation between a man and a woman. Water drinking lowered the rating scores of mating intentions as well as blood glucose (BG) levels. The sugary drink buffered this decline in sexual perceptivity. Overall, the change in BG levels was positively associated with changes in the ratings of mating intentions but was not associated with other likelihood ratings. These results suggest that both external cues of food and mating resources and internal BG fluctuation regulate the cognitive priority of physiological needs vs. mate acquisition and retention.

    1989-01-01

    The Nuclear Regulatory Commission (NRC) is proposing changes to 10CFR 71 transportation regulations to achieve compatibility with the 1985 IAEA regulations. The intent of these changes is to be more compatible with the international standard on shipping containers, package requirements, and performance criteria. The NRC has, however, modified part of its regulations to restrict the packaging of LSA by limiting the total activity rather than adopting the IAEA standard. This paper addresses how the proposed regulations will affect the low-level radioactive waste transportation industry. It describes the impacts on the transportation industry in three major areas-IAEA consistency, economic impact, and risk assessment. Available transport data from the Barnwell disposal site was used in the analysis of the proposed changes. The impacts addressed include possible increased radiation exposures, transportation risks and liability, transportation and processing costs, and waste disposal costs resulting in little health and safety benefit. Although the health and safety benefits of any change to the current regulations are minimal, suggested alternatives to the proposed regulations are discussed that more closely conform with the international standards while still maintaining health and safety

  1. Nuclear Protein Sam68 Interacts with the Enterovirus 71 Internal Ribosome Entry Site and Positively Regulates Viral Protein Translation.

    Enterovirus 71 (EV71) recruits various cellular factors to assist in the replication and translation of its genome. Identification of the host factors involved in the EV71 life cycle not only will enable a better understanding of the infection mechanism but also has the potential to be of use in the development of antiviral therapeutics. In this study, we demonstrated that the cellular factor 68-kDa Src-associated protein in mitosis (Sam68) acts as an internal ribosome entry site (IRES) trans-acting factor (ITAF) that binds specifically to the EV71 5' untranslated region (5'UTR). Interaction sites in both the viral IRES (stem-loops IV and V) and the heterogeneous nuclear ribonucleoprotein K homology (KH) domain of Sam68 protein were further mapped using an electrophoretic mobility shift assay (EMSA) and biotin RNA pulldown assay. More importantly, dual-luciferase (firefly) reporter analysis suggested that overexpression of Sam68 positively regulated IRES-dependent translation of virus proteins. In contrast, both IRES activity and viral protein translation significantly decreased in Sam68 knockdown cells compared with the negative-control cells treated with short hairpin RNA (shRNA). However, downregulation of Sam68 did not have a significant inhibitory effect on the accumulation of the EV71 genome. Moreover, Sam68 was redistributed from the nucleus to the cytoplasm and interacts with cellular factors, such as poly(rC)-binding protein 2 (PCBP2) and poly(A)-binding protein (PABP), during EV71 infection. The cytoplasmic relocalization of Sam68 in EV71-infected cells may be involved in the enhancement of EV71 IRES-mediated translation. Since Sam68 is known to be a RNA-binding protein, these results provide direct evidence that Sam68 is a novel ITAF that interacts with EV71 IRES and positively regulates viral protein translation. The nuclear protein Sam68 is found as an additional new host factor that interacts with the EV71 IRES during infection and could potentially

    The human plasma membrane sialidase NEU3 is a key enzyme in the catabolism of membrane gangliosides, is crucial in the regulation of cell surface processes, and has been demonstrated to be significantly up-regulated in renal cell carcinomas (RCCs). In this report, we show that NEU3 regulates β1 integrin trafficking in RCC cells by controlling β1 integrin recycling to the plasma membrane and controlling activation of the epidermal growth factor receptor (EGFR) and focal adhesion kinase (FAK)/protein kinase B (AKT) signaling. NEU3 silencing in RCC cells increased the membrane ganglioside content, in particular the GD1a content, and changed the expression of key regulators of the integrin recycling pathway. In addition, NEU3 silencing up-regulated the Ras-related protein RAB25, which directs internalized integrins to lysosomes, and down-regulated the chloride intracellular channel protein 3 (CLIC3), which induces the recycling of internalized integrins to the plasma membrane. In this manner, NEU3 silencing enhanced the caveolar endocytosis of β1 integrin, blocked its recycling and reduced its levels at the plasma membrane, and, consequently, inhibited EGFR and FAK/AKT. These events had the following effects on the behavior of RCC cells: they (a) decreased drug resistance mediated by the block of autophagy and the induction of apoptosis; (b) decreased metastatic potential mediated by down-regulation of the metalloproteinases MMP1 and MMP7; and (c) decreased adhesion to collagen and fibronectin. Therefore, our data identify NEU3 as a key regulator of the β1 integrin-recycling pathway and FAK/AKT signaling and demonstrate its crucial role in RCC malignancy. PMID:23139422

    Full Text Available The International Health Regulations (IHR (2005 require World Health Organization Member States to notify events fulfilling two of four criteria: (1 serious public health impact; (2 unusual or unexpected event; (3 significant risk of international spread; or (4 significant risk of international travel or trade restrictions.1 In-flight transmission of infections like severe acute respiratory syndrome is well documented.2 With the enormous amount of air travel today, the risk of increasing in-flight transmission and subsequent international spread of infections are increasing. Prompt notification and information sharing under the IHR mechanism is critical for effective contact tracing and prompt control measures. We report on a case of in-flight exposure to an infection with significant public health risks that was successfully resolved using IHR (2005 guidelines.

    Circulating monocytes bind 125 I-insulin in a specific fashion and have been used to analyze the ambient receptor status in humans. When freshly isolated circulating monocytes are incubated with 125 I-insulin and examined by electron microscopic autoradiography, approximately 18% of the labeled material is internalized after 15 minutes at 37 degrees C. By 2 hours at 37 degrees C, approximately one half of the 125 I-insulin is internalized. Internalization occurs also at 15 degrees C but at a slower rate. Furthermore, the monocytes bind and internalize 125 I-insulin in a manner that mirrors that of major target tissues, such as rat hepatocytes. These data suggest that the insulin receptor of the circulating monocyte might be regulated by adsorptive endocytosis in a manner analogous to that of target tissue, such as the liver

    The strain state of stacks of GaN/AlN quantum dots (QDs) grown on (0001) and (11 anti 20) 6H-SiC has been investigated by means of Raman spectroscopy. Depending on the orientation of the wurtzite axis with respect to the growth direction it is found that the piezoelectric contribution to the electrostatic potential may either reinforce that arising from the spontaneous polarization or oppose it. The experimental results are compared with a theoretical model for the strain and polarization field in QDs of both orientations that allows the calculation of the electrostatic potential in the QDs. Both the experimental results and the theoretical model indicate that the internal electric field and electrostatic potential are strongly reduced in the QDs grown on (11 anti 20) 6H-SiC as compared to those grown along the wurtzite c-axis.

    Much data suggest that receptor-mediated endocytosis is regulated in states of hormone excess. Thus, in hyperinsulinemic states there is an accelerated loss of cell surface insulin receptors. In the present experiments we addressed this question in hypoinsulinemic states, in which insulin binding to cell surface receptors is generally increased. In hepatocytes obtained from hypoinsulinemic streptozotocin-induced diabetic rats, [ 125 I]iodoglucagon internalization was increased, while at the same time [ 125 I]iodoinsulin internalization was decreased. The defect in [ 125 I]iodoinsulin internalization was corrected by insulin treatment of the animal. In peripheral blood monocytes from patients with type I insulinopenic diabetes, internalization of [ 125 I]iodoinsulin was impaired; this defect was not present in insulin-treated patients. These data in the hypoinsulinemic rat and human diabetes suggest that receptor-mediated endocytosis is regulated in states of insulin deficiency as well as insulin excess. Delayed or reduced internalization of the insulin-receptor complex could amplify the muted signal caused by deficient hormone secretion

    Certain organizational internal and external factors have been found to influence effective construction risk management within the construction company which has contributed to massive risk occurrence on the projects. Yet, the influence of the organizational factors such as effective communication, team competency with skills, active leadership, political factor, organizational culture, technology factor and economic factor on effective construction risk management among the construction companies operating in Abuja and Lagos state Nigeria have not received considerable attention. More so, a moderating variable is proposed. This paper proposes rules and regulations as the potential moderator on the relationship between organisational internal factors, external factors and effective construction risk management.

    It has been suggested that the agonist-induced internalization of G-protein-coupled receptors from the cell surface into intracellular compartments regulates cellular responsiveness. We previously reported that G q/11 -protein-coupled human histamine H 1 receptors internalized via clathrin-dependent mechanisms upon stimulation with histamine. However, the molecular determinants of H 1 receptors responsible for agonist-induced internalization remain unclear. In this study, we evaluated the roles of the intracellular C-terminal of human histamine H 1 receptors tagged with hemagglutinin (HA) at the N-terminal in histamine-induced internalization in Chinese hamster ovary cells. The histamine-induced internalization was evaluated by the receptor binding assay with [ 3 H]mepyramine and confocal immunofluorescence microscopy with an anti-HA antibody. We found that histamine-induced internalization was inhibited under hypertonic conditions or by pitstop, a clathrin terminal domain inhibitor, but not by filipin or nystatin, disruptors of the caveolar structure and function. The histamine-induced internalization was also inhibited by truncation of a single amino acid, Ser487, located at the end of the intracellular C-terminal of H 1 receptors, but not by its mutation to alanine. In contrast, the receptor-G-protein coupling, which was evaluated by histamine-induced accumulation of [ 3 H]inositol phosphates, was potentiated by truncation of Ser487, but was lost by its mutation to alanine. These results suggest that the intracellular C-terminal of human H 1 receptors, which only comprises 17 amino acids (Cys471-Ser487), plays crucial roles in both clathrin-dependent internalization of H 1 receptors and G-protein signaling, in which truncation of Ser487 and its mutation to alanine are revealed to result in biased signaling toward activation of G-proteins and clathrin-mediated internalization, respectively. © 2016 International Society for Neurochemistry.

    Pesticide self-poisoning accounts for 14-20% of suicides worldwide. Regulation aimed at restricting access to pesticides or banning highly hazardous pesticides is one approach to reducing these deaths. We systematically reviewed the evidence of the effectiveness of pesticide regulation in reducing the incidence of pesticide suicides and overall suicides. We did a systematic review of the international evidence. We searched MEDLINE, PsycINFO, and Embase for studies published between Jan 1, 1960, and Dec 31, 2016, which investigated the effect of national or regional bans, and sales or import restrictions, on the availability of one or more pesticides and the incidence of suicide in different countries. We excluded other interventions aimed at limiting community access to pesticides. We extracted data from studies presenting pesticide suicide data and overall suicide data from before and after national sales restrictions. Two reviewers independently assessed papers for inclusion, extracted data, and assessed risk of bias. We undertook a narrative synthesis of the data in each report, and where data were available for the years before and after a ban, we pooled data for the 3 years before and the 3 years after to obtain a crude estimate of the effect of the ban. This study is registered through PROSPERO, number CRD42017053329. We identified 27 studies undertaken in 16 countries-five low-income or middle-income countries (Bangladesh, Colombia, India, Jordan and Sri Lanka), and 11 high-income countries (Denmark, Finland, Germany, Greece, Hungary, Ireland, Japan, South Korea, Taiwan, UK, and USA). Assessments largely focused on national bans of specific pesticides (12 studies of bans in six countries-Jordan, Sri Lanka, Bangladesh, Greece [Crete], South Korea, and Taiwan) or sales restrictions (eight studies of restrictions in five countries- India, Denmark, Ireland, the UK and the USA). Only five studies used optimum analytical methods. National bans on commonly ingested

    IL-33, a relatively new member of the IL-1 cytokine family, plays a crucial role in allergic inflammation and acute lung injury. Long form ST2 (ST2L), the receptor for IL-33, is expressed on immune effector cells and lung epithelia and plays a critical role in triggering inflammation. We have previously shown that ST2L stability is regulated by the ubiquitin-proteasome system; however, its upstream internalization has not been studied. In this study, we demonstrate that glycogen synthase kinase 3β (GSK3β) regulates ST2L internalization and IL-33 signaling. IL-33 treatment induced ST2L internalization, and an effect was attenuated by inhibition or downregulation of GSK3β. GSK3β was found to interact with ST2L on serine residue 446 in response to IL-33 treatment. GSK3β binding site mutant (ST2L(S446A)) and phosphorylation site mutant (ST2L(S442A)) are resistant to IL-33-induced ST2L internalization. We also found that IL-33 activated focal adhesion kinase (FAK). Inhibition of FAK impaired IL-33-induced GSK3β activation and ST2L internalization. Furthermore, inhibition of ST2L internalization enhanced IL-33-induced cytokine release in lung epithelial cells. These results suggest that modulation of the ST2L internalization by FAK/GSK3β might serve as a unique strategy to lessen pulmonary inflammation.

    Full Text Available It is always desirable to know the interior deformation pattern when a rock is subjected to mechanical load. Few experimental techniques exist that can represent full-field three-dimensional (3D strain distribution inside a rock specimen. And yet it is crucial that this information is available for fully understanding the failure mechanism of rocks or other geomaterials. In this study, by using the newly developed digital volumetric speckle photography (DVSP technique in conjunction with X-ray computed tomography (CT and taking advantage of natural 3D speckles formed inside the rock due to material impurities and voids, we can probe the interior of a rock to map its deformation pattern under load and shed light on its failure mechanism. We apply this technique to the analysis of a red sandstone specimen under increasing uniaxial compressive load applied incrementally. The full-field 3D displacement fields are obtained in the specimen as a function of the load, from which both the volumetric and the deviatoric strain fields are calculated. Strain localization zones which lead to the eventual failure of the rock are identified. The results indicate that both shear and tension are contributing factors to the failure mechanism.

    Full Text Available Abstract Background Flow cytometry based adherence assay is a potentially powerful but little used method in the study of bacterial binding to host structures. We have previously characterized a glycoprotein-binding activity in Streptococcus pyogenes called 'strepadhesin' binding to thyroglobulin, submaxillar mucin, fetuin and asialofetuin. We have identified surface-associated pullulanase (PulA and cysteine protease (SpeB as carriers of strepadhesin activity. In the present paper, we investigated the use of flow cytometry as a method to study the binding of Rgg, SpeB and PulA knock-out strains to cultured human epithelial cells. Results Streptococcal mutants were readily labelled with CFDA-SE and their binding to epithelial cells could be effectively studied by flow cytometry. A strain deficient in Rgg expression showed increased binding to the analyzed epithelial cell lines of various origin. Inactivation of SpeB had no effect on the adhesion, while PulA knock-out strains displayed decreased binding to the cell lines. Conclusion These results suggest that the flow cytometric assay is a valuable tool in the analysis of S. pyogenes adherence to host cells. It appears to be an efficient and sensitive tool for the characterization of interactions between the bacteria and the host at the molecular level. The results also suggest a role for Rgg regulated surface molecules, like PulA, in the adhesion of S. pyogenes to host cells.

    Full Text Available The financial crisis 2007-2009 will not be forgotten in a hurry because of its impact on the global financial system almost replicating the Great Depression. Major and causal factors contributed to the financial crisis, and this prompted the establishment of Basel III to contain the crisis. Basel III introduced improved capital and liquidity rules, but still could not contain the crisis. This leaves regulators with questions of how to prevent another financial crisis in the future. Evidences suggest that the financial market is evolving because of its complex and changing nature, and so are the international banking regulations (Basel I, Basel II and Basel III that support the system in terms of maintaining economic and financial stability. It is clear that Basel III will not stop the next financial crisis even though the Basel accords continue to evolve in response to maintaining economic and financial stability, with the core purpose of preventing another financial crisis. Uncertainties lies ahead, and regulators cannot be sure of what will likely cause the next crisis, but indications suggest that the financial markets and international banking regulations in the form of Basel accords will continue to evolve

    To identify lessons learned from 30 years of implementing the International Code of Marketing of Breast-milk Substitutes (‘the Code’) and identify lessons learned for the regulation of marketing foods and beverages to children. Historical analysis of 30 years of implementing the Code. Latin America and the Caribbean. None. Legislation to restrict marketing of breast-milk substitutes is necessary but not sufficient; equally important are the promulgation of implementing regulations, effective enforcement and public monitoring of compliance. A system of funding for regular monitoring of compliance with legislation should be explicitlyd eveloped and funded from the beginning. Economic sanctions, while important, are likely to be less effective than reports that affect a company’s public image negatively. Non-governmental organizations play a critical role in leveraging public opinion and galvanizing consumer pressure to ensure that governments adopt regulations and companies adhere to them. Continual clinical, epidemiological and policy research showing the link between marketing and health outcomes and between policy and better health is essential. Implementation of the Code has not come easily as it places the interests of underfinanced national governments and international and non-governmental organizations promoting breast-feeding against those of multinational corporations that make hundreds of millions of dollars annually marketing infant formulas. Efforts to protect, promote and support breast-feeding have been successful with indicators of breast-feeding practices increasing globally. The lessons learned can inform current efforts to regulate the marketing of foods and beverages to children.

    The occurrence of hypoxic conditions in plants not only represents a stress condition but is also associated with the normal development and growth of many organs, leading to adaptive changes in metabolism and growth to prevent internal anoxia. Internal oxygen concentrations decrease inside growing potato tubers, due to their active metabolism and increased resistance to gas diffusion as tubers grow. In the present work, we identified three hypoxia-responsive ERF (StHRE) genes whose expression is regulated by the gradual decrease in oxygen tensions that occur when potato tubers grow larger. Increasing the external oxygen concentration counteracted the modification of StHRE expression during tuber growth, supporting the idea that the actual oxygen levels inside the organs, rather than development itself, are responsible for the regulation of StHRE genes. We identified several sugar metabolism-related genes co-regulated with StHRE genes during tuber development and possibly involved in starch accumulation. All together, our data suggest a possible role for low oxygen in the regulation of sugar metabolism in the potato tuber, similar to what happens in storage tissues during seed development.

    This short communication presents a synthesis of a Working Group on Carbon Emission Policy and Regulation held at the University of Sao Paulo, in Brazil. The document looked at the problems with the international negotiations, the options for Brazil as it attempts to control emissions, and ways to leverage the mitigation process. Several options are currently being proposed, but these are neither clear in order to support a solid polycentric approach with adequate metrics, nor a robust international coordination and a sound scientific communication. Brazil has a central role in this process, for having successful initiatives on renewable energy and deforestation control. Its leadership can demonstrate how such policies might take shape. However, the country´s future is uncertain in terms of low carbon development. Although the country is still well positioned among BRICS to find practical solutions to the stalemate in international cooperation, several internal challenges need to be harmonized. - Highlights: • The work presents results of a recent climate change mitigation policies workshop. • It assesses Brazil's potential role in shaping future policies and negotiations. • Policies are evaluated based on domestic and international effects. • Suggests how Brazil's national effort could leverage the international processes

    A putative member of the Lrp/AsnC family of transcriptional regulators, ST1022 from S. tokodaii strain 7, has been purified and crystallized in the absence and presence of the effector l-glutamine. A molecular-replacement solution was found using the FL11 transcriptional regulator from Pyrococcus sp. OT3 as a model and structural refinement is under way. The Lrp/AsnC family of transcriptional regulators, also known as feast/famine transcriptional regulators, are widely distributed among bacteria and archaea. This family of proteins are likely to be involved in cellular metabolism, with exogenous amino acids functioning as effectors. Here, the crystallization and preliminary X-ray diffraction analysis of ST1022, a member of the Lrp/AsnC family of proteins, is reported with and without exogenous glutamine as the effector molecule. The crystals of native ST1022 and of the putative complex belong to the tetragonal space group I422, with unit-cell parameters a = b = 103.771, c = 73.297 Å and a = b = 103.846, c = 73.992 Å, respectively. Preliminary X-ray diffraction data analysis and molecular-replacement solution revealed the presence of one monomer per asymmetric unit.

    Synchrotron X-ray microbeam diffraction was used to measure the full elastic long range internal strain and stress tensors of low dislocation density regions within the submicrometer grain/subgrain structure of equal-channel angular pressed (ECAP) aluminum alloy AA1050 after 1, 2, and 8 passes using route B C . This is the first time that full tensors were measured in plastically deformed metals at this length scale. The maximum (most tensile or least compressive) principal elastic strain directions for the unloaded 1 pass sample for the grain/subgrain interiors align well with the pressing direction, and are more random for the 2 and 8 pass samples. The measurements reported here indicate that the local stresses and strains become increasingly isotropic (homogenized) with increasing ECAP passes using route B C . The average maximum (in magnitude) LRISs are −0.43 σ a for 1 pass, −0.44 σ a for 2 pass, and 0.14 σ a for the 8 pass sample. These LRISs are larger than those reported previously because those earlier measurements were unable to measure the full stress tensor. Significantly, the measured stresses are inconsistent with the two-component composite model.

    Alzheimer's disease (AD) is one of the most devastating neurodegenerative disorders. Intracellular β-amyloid protein (Aβ) is an early event in AD. It induces the formation of amyloid plaques and neuron damage. The α7 nicotinic acetylcholine receptor (α7nAChR) has been suggested to play an important role in Aβ caused cognition. It has high affinity with Aβ and could mediate Aβ internalization in vitro. However, whether in mouse brain the p38 MAPK signaling pathway is involved in the regulation of the α7nAChR mediated Aβ internalization and their role in mitochondria remains little known. Therefore, in this study, we revealed that Aβ is internalized by cholinergic and GABAergic neurons. The internalized Aβ were found deposits in lysosomes/endosomes and mitochondria. Aβ could form Aβ-α7nAChR complex with α7nAChR, activates the p38 mitogen activated protein kinase (MAPK). And the increasing of α7nAChR could in return mediate Aβ internalization in the cortex and hippocampus. In addition, by using the α7nAChR agonist PNU282987, the p38 phosphorylation level decreases, rescues the biochemical changes which are tightly associated with Aβ-induced apoptosis, such as Bcl2/Bax level, cytochrome c (Cyt c) release. Collectively, the p38 MAPK signaling pathway could regulate the α7nAChR-mediated internalization of Aβ. The activation of α7nAChR or the inhibition of p38 MAPK signaling pathway may be a beneficial therapy to AD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Prevotella intermedia is an oral bacterium implicated in a variety of oral diseases. Although internalization of this bacterium by nonphagocytic host cells is well established, the molecular players mediating the process are not well known. Here, the properties of a leucine-rich repeat (LRR) domain protein, designated AdpF, are described. This protein contains a leucine-rich region composed of 663 amino acid residues, and molecular modeling shows that it folds into a classical curved solenoid structure. The cell surface localization of recombinant AdpF (rAdpF) was confirmed by electron and confocal microscopy analyses. The recombinant form of this protein bound fibronectin in a dose-dependent manner. Furthermore, the protein was internalized by host cells, with the majority of the process accomplished within 30 min. The internalization of rAdpF was inhibited by nystatin, cytochalasin, latrunculin, nocodazole, and wortmannin, indicating that microtubules, microfilaments, and signal transduction are required for the invasion. It is noteworthy that preincubation of eukaryotic cells with AdpF increased P. intermedia 17 internalization by 5- and 10-fold for HeLa and NIH 3T3 fibroblast cell lines, respectively. The addition of the rAdpF protein was also very effective in inducing bacterial internalization into the oral epithelial cell line HN4, as well as into primary cells, including human oral keratinocytes (HOKs) and human umbilical vein endothelial cells (HUVECs). Finally, cells exposed to P. intermedia 17 internalized the bacteria more readily upon reinfection. Taken together, our data demonstrate that rAdpF plays a role in the internalization of P. intermedia 17 by a variety of host cells.

    Nontumorigenic Agrobacterium vitis strain F2/5 is able to prevent crown gall caused by tumorigenic A. vitis on grape but not on other plant species such as tobacco. Mutations in a quorum-sensing transcription factor, aviR, and in caseinolytic protease (clp) component genes clpA and clpP1 resulted in reduced or loss of biological control. All mutants were complemented; however, restoration of biological control by complemented clpA and clpP1 mutants was dependent on the copy number of vector that was used as well as timing of application of the complemented mutants to grape wounds in relation to inoculation with pathogen. Mutations in other quorum-sensing and clp genes and in a gene associated with polyketide synthesis did not affect biological control. It was determined that, although F2/5 inhibits transformation by tumorigenic A. vitis strains on grape, it does not affect growth of the pathogen in wounded grape tissue over time.

  11. Strain Identity of the Ectomycorrhizal Fungus Laccaria bicolor Is More Important than Richness in Regulating Plant and Fungal Performance under Nutrient Rich Conditions

    Full Text Available Effects of biodiversity on productivity are more likely to be expressed when there is greater potential for niche complementarity. In soil, chemically complex pools of nutrient resources should provide more opportunities for niche complementarity than chemically simple pools. Ectomycorrhizal (ECM fungal genotypes can exhibit substantial variation in nutrient acquisition traits and are key components of soil biodiversity. Here, we tested the hypothesis that increasing the chemical complexity and forms of soil nutrients would enhance the effects of intraspecific ECM diversity on host plant and fungal productivity. In pure culture, we found substantial variation in growth of strains of the ECM fungus Laccaria bicolor on a range of inorganic and organic forms of nutrients. Subsequent experiments examined the effects of intraspecific identity and richness using Scots pine (Pinus sylvestris seedlings colonized with different strains of L. bicolor growing on substrates supplemented with either inorganic or organic forms of nitrogen and phosphorus. Intraspecific identity effects on plant productivity were only found under the inorganic nutrient amendment, whereas intraspecific identity affected fungal productivity to a similar extent under both nutrient treatments. Overall, there were no significant effects of intraspecific richness on plant and fungal productivity. Our findings suggest soil nutrient composition does not interact strongly with ECM intraspecific richness, at least under experimental conditions where mineral nutrients were not limiting. Under these conditions, intraspecific identity of ECM fungi becomes more important than richness in modulating plant and fungal performance.

  12. Follicle-stimulating hormone (FSH) activates extracellular signal-regulated kinase phosphorylation independently of beta-arrestin- and dynamin-mediated FSH receptor internalization

    2006-01-01

    Background The follicle-stimulating hormone receptor (FSH-R) is a seven transmembrane spanning receptor (7TMR) which plays a crucial role in male and female reproduction. Upon FSH stimulation, the FSH-R activates the extracellular signal-regulated kinases (ERK). However, the mechanisms whereby the agonist-stimulated FSH-R activates ERK are poorly understood. In order to activate ERK, some 7 TMRs require beta-arrestin-and dynamin-dependent internalization to occur, whereas some others do not. In the present study, we examined the ability of the FSH-activated FSH-R to induce ERK phosphorylation, in conditions where its beta-arrestin- and dynamin-mediated internalization was impaired. Methods Human embryonic kidney (HEK) 293 cells were transiently transfected with the rat FSH-R. Internalization of the FSH-R was manipulated by co-expression of either a beta-arrestin (319–418) dominant negative peptide, either an inactive dynamin K44A mutant or of wild-type beta-arrestin 1 or 2. The outcomes on the FSH-R internalization were assayed by measuring 125I-FSH binding at the cell surface when compared to internalized 125I-FSH binding. The resulting ERK phosphorylation level was visualized by Western blot analysis. Results In HEK 293 cells, FSH stimulated ERK phosphorylation in a dose-dependent manner. Co-transfection of the beta- arrestin (319–418) construct, or of the dynamin K44A mutant reduced FSH-R internalization in response to FSH, without affecting ERK phosphorylation. Likewise, overexpression of wild-type beta-arrestin 1 or 2 significantly increased the FSH-R internalization level in response to FSH, without altering FSH-induced ERK phosphorylation. Conclusion From these results, we conclude that the FSH-R does not require beta-arrestin- nor dynamin-mediated internalization to initiate ERK phosphorylation in response to FSH. PMID:16787538

  13. An under-active or over-active internal world? An exploration of parallel dynamics within psyche and soma, and the difficulty of internal regulation, in patients with Chronic Fatigue Syndrome and Myalgic Encephalomyelitis.

    This paper explores the dynamics brought into analytic work when there is a symmetric fusion between psyche and soma within the patient. It will consider how such a fusion may emerge from reverberations between physical constitution and a lack of maternal attunement, containment and reflective function. I will describe the work with a patient, Jane, who was diagnosed with Myalgic Encephalomyelitis (ME) during the course of her analysis. The dynamic of her physical symptoms within the analytic work, and the impact of her internal affects and internal 'objects' within the transference and countertransference, indicated a difficulty in finding an homeostatic balance resulting in overactivity and underactivity at both somatic and psychological levels. Using the clinical work with Jane this paper will also examine the interrelationship between mother-infant attachment, an inadequate internalized maternal reflective function, affect dysregulation, unconscious fusion, the lack of psyche-soma differentiation and the impact of the latter in relation to internal regulation systems, or lack of, in patients with Chronic Fatigue Syndrome (CFS) and Myalgic Encephalomyelitis (ME). I will draw on similar work carried out by Holland (1997), Simpson (1997) and Simpson et al. (1997). The paper will also employ the concept of the reflective function (Fonagy 2001; Knox 2003), and consider Matte-Blanco's (1999) concepts of generalization and unconscious symmetry in relation to the patient's internal world. I go on to consider how analysis provides a point outside the 'fusion' that can enable the 'deadlock' to be broken.

    For the past two decades, international climate policy has been handled as a matter for State to State deliberation. Non-state actors have played at best marginal roles in making and implementing international policy. This paper argues that climate change remains an intractable transnational problem because State to State deliberations failed to acknowledge that both climate mitigation and adaptation require ongoing collaborative governance with non-State actors to shift normative behavior.

  17. The NifA-RpoN regulon of Mesorhizobium loti strain R7A and its symbiotic activation by a novel LacI/GalR-family regulator.

    Directory of Open Access Journals (Sweden)

    John T Sullivan

    Full Text Available Mesorhizobium loti is the microsymbiont of Lotus species, including the model legume L. japonicus. M. loti differs from other rhizobia in that it contains two copies of the key nitrogen fixation regulatory gene nifA, nifA1 and nifA2, both of which are located on the symbiosis island ICEMlSym(R7A. M. loti R7A also contains two rpoN genes, rpoN1 located on the chromosome outside of ICEMlSym(R7A and rpoN2 that is located on ICEMlSym(R7A. The aims of the current work were to establish how nifA expression was activated in M. loti and to characterise the NifA-RpoN regulon. The nifA2 and rpoN2 genes were essential for nitrogen fixation whereas nifA1 and rpoN1 were dispensable. Expression of nifA2 was activated, possibly in response to an inositol derivative, by a novel regulator of the LacI/GalR family encoded by the fixV gene located upstream of nifA2. Other than the well-characterized nif/fix genes, most NifA2-regulated genes were not required for nitrogen fixation although they were strongly expressed in nodules. The NifA-regulated nifZ and fixU genes, along with nifQ which was not NifA-regulated, were required in M. loti for a fully effective symbiosis although they are not present in some other rhizobia. The NifA-regulated gene msi158 that encodes a porin was also required for a fully effective symbiosis. Several metabolic genes that lacked NifA-regulated promoters were strongly expressed in nodules in a NifA2-dependent manner but again mutants did not have an overt symbiotic phenotype. In summary, many genes encoded on ICEMlSym(R7A were strongly expressed in nodules but not free-living rhizobia, but were not essential for symbiotic nitrogen fixation. It seems likely that some of these genes have functional homologues elsewhere in the genome and that bacteroid metabolism may be sufficiently plastic to adapt to loss of certain enzymatic functions.

    This paper intends to compare the Brasilian basic regulation on radiological protection with the new recommendations of ICRP through existent differences. The main difference between the publication 60 and the publication 103 of the ICRP is the changing of concept of protection based on the process by use of practice and intervention concepts, to the protection based on the exposure situation, through the concepts of planned exposure, emergency and existent situation. For adequacy to the Brazilian regulation it is necessary to change its concept of protection and the values of radiation weighing and tissues, up dating of radiation detriments, besides to make clear the concept of environmental radioprotection

    Full Text Available The article presents the results of space experiment “Pneumocard”. The investigation involved all 25 Russian members of the ISS crew. The total of 226 sessions were made including 130 aboard the ISS, 50 prior to launch and 46 on return from mission. The objective was to study effects of the spaceflight factors on autonomic regulation of blood circulation, respiration and cardiac contractility during long-duration mission. The purpose was to secure new research data that would clarify our present view of adaptation mechanisms. Registered were the following signals: electrocardiogram, impedance cardiogram, seismic cardiogram, pneumotachogram, finger photoplethysmogram. A set of hard- and software was used. Autonomic regulation of blood circulation by HRV analysis was investigated. It was shown that at the onset of a space mission parasympathetic involvement in regulation increases typically with subsequent mobilization of additional functional reserve. It guided the development of a functional states mathematical model incorporating the established types of autonomic regulation. Our data evidence that the combination of HRV analysis, pre-nosology diagnosis and probabilistic estimate of the pathology risk can reinforce the medical care program in space missions.

This study examines the immediate and long term effectiveness of advertising restrictions enacted in different countries on exposure to different forms of product marketing, and examines differences in exposure across different socioeconomic status (SES groups. Nationally representative data from the United Kingdom, Canada, Australia, and the United States, collected from adult smokers between 2002 and 2008 using the International Tobacco Control Four Country Survey (ITC-4, were used in this study (N = 21,615. In light of the specific marketing regulation changes that occurred during the course of this study period, changes in awareness of tobacco marketing via various channels were assessed for each country, and for different SES groups within countries. Tobacco marketing regulations, once implemented, were associated with significant reductions in smokers’ reported awareness of pro-smoking cues, and the observed reductions were greatest immediately following the enactment of regulations. Changes in reported awareness were generally the same across different SES groups, although some exceptions were noted. While tobacco marketing regulations have been effective in reducing exposure to certain types of product marketing there still remain gaps, especially with regard to in-store marketing and price promotions.

    Full Text Available Trigonella foenum-graecum L. (Fenugreek is an important plant of the Leguminosae family known to have medicinal properties. However, fraction based antiquorum sensing and antibiofilm activities have not been reported from this plant. In the present study T. foenum-graecum seed extract was sequentially fractionated and sub-MICs were tested for above activities. The methanol fraction of the extract demonstrated significant inhibition of AHL regulated virulence factors: protease, LasB elastase, pyocyanin production, chitinase, EPS, and swarming motility in Pseudomonas aeruginosa PAO1 and PAF79. Further, QS dependent virulence factor in the aquatic pathogen Aeromonas hydrophila WAF38 was also reduced. Application of T. foenum-graecum seed extract to PAO1, PAF79, and WAF38 decreased the biofilm forming abilities of the pathogens by significant levels. The extract also exhibited reduced AHL levels and subsequent downregulation of lasB gene. In vivo study showed an enhanced survival of PAO1-preinfected C. elegans after treatment with extract at 1 mg/mL. Further, the major compound detected by GC-MS, caffeine, reduced the production of QS regulated virulence factors and biofilm at 200 µg/mL concentration indicating its role in the activity of the methanol extract. The results of the present study reveal the potential anti-QS and antibiofilm property of T. foenum-graceum extract and caffeine.

    The Cognitive Emotion Regulation Questionnaire (CERQ) is a cognitive and emotional tool measuring how individuals deal with stressful life events. However differences exist in the results of CERQ among individuals. This study was conducted to investigate the CERQ results and depressive symptoms of students at our university (both local and international students) in order to provide further guidance for psychological interventions. 255 sophomore and junior international students (171 male and 84 female) and 262 sophomore and junior Chinese students (124 male and 138 female) were investigated using CERQ, ASLEC and SDS questionnaires. Results were analyzed using SPSS 16.0. Compared to Chinese students, international students more often used cognitive adjustment methods such as "positive refocusing","re-focus on planning" and "catastrophizing". In regression equations where depression symptoms were used as the dependent variable, "self-blaming" and "catastrophizing"positively contributed to depression symptoms in international students, while"acceptance" was negatively correlated with depression symptoms.In Chinese students, "life events score" and "catastrophizing"were positively correlated withdepression symptoms, while "positive re-evaluating" was negatively correlated with depression symptoms. Among students of different races, positive coping methods were negatively correlated with depression symptoms and could possibly prevent the occurrence of depression, while negative coping methods were positively correlated with depression.Encouraging students to use adaptive coping methods during psychological intervention is an effective way to adjust cognitions and behavior for depression prevention.

    The interface between bone and bone marrow is examined in relation to radiation effects, with attention to new concepts of hematopoiesis. Such concepts propose a functional role of stroma in regulating the commitment of pluripotent stem cells as well as in the production of colony stimulating activity (CSA) including candidate granulopoietin(s). Morphologic examples are included, underlining the concept that stroma (including bone) and hematopoietic elements respond as a functional unit to injury to marrow elements. The methylcellulose bone marrow culture system is reviewed as it may relate to a method for quantitation of hematopoietic colonies (CFU-C), humoral regulators for granulopoiesis (CSA), and potentially as a method of quantitating mesenchymal progenitor populations (PFU-C). Based on these and other observations cited, a model depicting a tentative positioning of cells at risk relative to bone-seeking radionuclides is presented

    The safety record of transporting radioactive material is remarkable; globally with tens of millions of packages transported; each year with approximately 2-3% is related to the nuclear industry. Much of this success is due to the ongoing commitment made by the IAEA and its Member States to maintain over the past 50 years the prescriptive regulations for the transport of radioactive material (TS-R-1) and its associated guidance documents. TS-R-1 is by far the most popular IAEA document in terms of downloads and sales with some Member States adopting them directly into their domestic legal framework whilst others adopt them due to all of the TS-R-1 requirements being incorporated into the UN Model Regulations

    Diverse international organizations have evaluated the risk of lung cancer starting from epidemic studies in miners of uranium mines, where the corresponding effective dose was determined relating with the dose received by the population during Hiroshima and Nagasaki events. Alternately, the equivalent dose has been calculated by means of based models on the energy deposited by the breathable radon fractions and its decay products in the breathing ducts. A unique factor agreed by the diverse organizations that allows converting radon concentration to effective dose does not exist. Neither an agreement exists among the different countries on which duty to be the value of the maximum concentration of radon, in interiors starting from which an intervention is required and if this intervention is standardized, recommended or nonexistent. In this work study cases in Mexico are presented and their interpretation alternative based on the international agreements absence. (Author)

    Full Text Available Abstract Background The use of live microorganisms to influence positively the course of intestinal disorders such as infectious diarrhea or chronic inflammatory conditions has recently gained increasing interest as a therapeutic alternative. In vitro and in vivo investigations have demonstrated that probiotic-host eukaryotic cell interactions evoke a large number of responses potentially responsible for the effects of probiotics. The aim of this study was to improve our understanding of the E. coli Nissle 1917-host interaction by analyzing the gene expression pattern initiated by this probiotic in human intestinal epithelial cells. Methods Gene expression profiles of Caco-2 cells treated with E. coli Nissle 1917 were analyzed with microarrays. A second human intestinal cell line and also pieces of small intestine from BALB/c mice were used to confirm regulatory data of selected genes by real-time RT-PCR and cytometric bead array (CBA to detect secretion of corresponding proteins. Results Whole genome expression analysis revealed 126 genes specifically regulated after treatment of confluent Caco-2 cells with E. coli Nissle 1917. Among others, expression of genes encoding the proinflammatory molecules monocyte chemoattractant protein-1 ligand 2 (MCP-1, macrophage inflammatory protein-2 alpha (MIP-2α and macrophage inflammatory protein-2 beta (MIP-2β was increased up to 10 fold. Caco-2 cells cocultured with E. coli Nissle 1917 also secreted high amounts of MCP-1 protein. Elevated levels of MCP-1 and MIP-2α mRNA could be confirmed with Lovo cells. MCP-1 gene expression was also up-regulated in mouse intestinal tissue. Conclusion Thus, probiotic E. coli Nissle 1917 specifically upregulates expression of proinflammatory genes and proteins in human and mouse intestinal epithelial cells.

    The 2014/15 Ebola virus disease (EVD) outbreak in West Africa has highlighted the inherent weaknesses associated with the implementation of the International Health Regulations (IHR). In this perspective article, the lessons learnt from the outbreak are used to review the challenges impeding effective implementation of the IHR and to propose policy and strategic options for enhancing its application. While some progress has been achieved in implementing the IHR in several countries, numerous challenges continue to impede its effectiveness, especially in developing countries, such as those affected by the West Africa EVD outbreak. Political and economic sensitivities associated with reporting public health emergencies of international concern (PHEIC), inadequate resources (human and financial), and lack of technical know-how required for implementation of the IHR are weaknesses that continue to constrain the implementation of the regulations. In view of the complex sociopolitical, cultural, and public health dimensions of PHEICs, frameworks, such as the IHR, which have legal backing, seem to be the most effective and sustainable option for assuring timely detection, notification, and response to such events. Renewed efforts to strengthen national and global institutional frameworks for implementation of the IHR are therefore required. Improvements in transparency, commitment, and accountability of parties to the IHR, mainstreaming of the IHR into national public health governance structures, use of multidisciplinary approaches, and mobilization of the required resources for the implementation of the IHR are imperative.

    In the recent past, we have seen an increase in the outsourcing of bioanalysis in pharmaceutical companies in support of their drug development pipeline. This trend is largely driven by the effort to reduce internal cost, especially in support of late-stage pipeline assets where established bioanalytical assays are used to analyze a large volume of samples. This article will highlight our perspective of how bioanalytical laboratories within pharmaceutical companies can be developed into the best partner in the advancement of drug development pipelines with high-quality support at competitive cost.

    Non-alcoholic fatty liver disease (NAFLD) is a common disease that is concomitant with obesity, resulting in increased mortality. To date, the efficiency of NAFLD treatment still needs to be improved. Therefore, we aimed to evaluate the effect of Lactobacillus mali APS1, which was isolated from sugary kefir, on hepatic steatosis in rats fed a high-fat diet (HFD). Sprague Dawley rats were fed a control diet, a HFD with saline, and a HFD with APS1 intervention by gavage daily for 12 weeks. The results showed that APS1 significantly reduced body weight and body weight gain in HFD-fed rats. APS1 reduced hepatic lipid accumulation by regulating SIRT-1/PGC-1α/SREBP-1 expression. Moreover, APS1 increased hepatic antioxidant activity by modulating Nrf-2/HO-1 expression. Notably, APS1 manipulated the gut microbiota, resulting in increasing proportions of the phylum Bacteroidetes/Firmicutes and reducing the abundance of specific NAFLD-associated bacteria. These results suggested that APS1 ameliorated hepatic steatosis by modulating lipid metabolism and antioxidant activity via manipulating specific NAFLD-associated gut microbiota in vivo. © 2018 WILEY-VCH Verlag GmbH & Co.

    We studied Cd accumulation in Cepaea nemoralis snails at low, but field-relevant Cd concentrations in the diet (Urtica dioica leaves). Six treatments of U. dioica plants were grown, resulting in leaf Cd concentrations between 0 and 2.6 μg g -1 dw. Seven snails per treatment were fed for 38 days. Leaf Cd concentrations did not affect food consumption rates, and consequently Cd intake rates increased with increasing leaf concentrations. No differences were detected among treatments in the final soft tissue Cd concentrations and body burdens in the snails. Regression analyses showed no positive relationship between either snail Cd concentrations or body burdens and total Cd intake. This suggests a regulation of internal Cd concentrations at low food Cd concentrations. Our data suggest that Cd excretion via the mucus plays a substantial role in this regulation, in addition to Cd excretion via the faeces. Snail shells were no sinks for Cd. - Cd excretion via the mucus plays a substantial role in the regulation of C. nemoralis soft tissue Cd concentrations at low, but field-relevant Cd concentrations in the food

    Founded in 1996 upon the initiative of the “Group of 8” governments (G8), the Nuclear Forensics International Technical Working Group (ITWG) is an ad hoc organization of official Nuclear Forensics practitioners (scientists, law enforcement, and regulators) that can be called upon to provide technical assistance to the global community in the event of a seizure of nuclear or radiological materials. The ITWG is supported by and is affiliated with nearly 40 countries and international partner organizations including the International Atomic Energy Agency (IAEA), EURATOM, INTERPOL, EUROPOL, and the United Nations Interregional Crime and Justice Research Institute (UNICRI) (Figure 1). Besides providing a network of nuclear forensics laboratories that are able to assist the global community during a nuclear smuggling event, the ITWG is also committed to the advancement of the science of nuclear forensic analysis, largely through participation in periodic table top and Collaborative Materials Exercises (CMXs). Exercise scenarios use “real world” samples with realistic forensics investigation time constraints and reporting requirements. These exercises are designed to promote best practices in the field and test, evaluate, and improve new technical capabilities, methods and techniques in order to advance the science of nuclear forensics. Past efforts to advance nuclear forensic science have also included scenarios that asked laboratories to adapt conventional forensics methods (e.g. DNA, fingerprints, tool marks, and document comparisons) for collecting and preserving evidence comingled with radioactive materials.

    Multidrug-resistant Acinetobacter baumannii infections are serious challenges for clinicians because of A. baumannii propensity to acquire resistance to a wide spectrum of antimicrobial agents. In this study, 91 A. baumannii isolates from patients in tertiary intensive care units of three university hospitals in the north, central, and south of Iran were selected and tested for susceptibility to 22 antimicrobials; amplified restriction fragment polymorphism and multiplex polymerase chain reaction methods were used to determine genetic relationships and International Clone (IC) of A. baumannii isolates, respectively. Twenty-four genotypes were identified in A. baumannii isolates. About 91.2% of isolates categorized into 4 distinct clusters; one was more heterogeneous and observed across the three locations. A considerable number of the isolates (27.5%) belonged to the novel IC variant, sequence group 7 (SG7), which was geographically widespread in three locations. The drug resistance pattern showed that 14.2%, 20%, and 77% of the A. baumannii isolates were resistant to colistin, tigecycline, and rifampicin, respectively. Nine percent of isolates (8) showed simultaneous resistance to colistin, rifampicin, and tigecycline. Interestingly, all of them were susceptible to ampicillin-sulbactam and/or tobramycin. According to our results, SG7 could be considered as a pan-Iranian clone.

    The European competition rules restrict governments' opportunity to differentiate terms of energy accessibility among firms and industries. This easily runs counter with regional and industrial goals of national energy policies. Norway levies a tax on use of electricity, but exempts main industrial usages. This analysis assesses alternative, internationally legal, designs of the system in terms of their effects on efficiency and distribution, including industrial objectives. Among the reforms we explore, removing the exemptions would be the most effective way of raising revenue, but it would be politically costly by deteriorating the competitiveness of today's favoured industries. An entire abolishment of the electricity tax, and replacing revenue by increased VAT, would generate a more equal distribution of standard of living and, at the same time, avoid the trade-off between efficiency and competitiveness

  14. Access to essential medicines for sexual and reproductive health care: the role of the pharmaceutical industry and international regulation.

    2011-11-01

    The range of medicines and technologies that are essential for sexual and reproductive health care is well established, but access to them is far from universally assured, particularly in less developed countries. This paper shows how the pharmaceutical industry plays a major role in the lack of access to essential medicines for sexual and reproductive health care, by a) investing in products for profit-making reasons despite their negative health impact (e.g. hormone replacement therapy), b) marketing new essential medicines at prices beyond the reach of countries that most need them (e.g. HPV vaccines), and c) failing to invest in the development of new products (e.g. microbicides and medical abortion pills). Small companies, some of them non-profit-making, struggle to fill some of that demand (e.g. for female condoms). International patent protection contributes to high prices of medicines, and while international agreements such as compulsory licensing under TRIPS and the Medicines Patent Pool allow for mechanisms to enable poorer countries to get access to essential medicines, the obstacles created by "big pharma" are daunting. All these barriers have fostered a market in sub-standard medicines (e.g. fake medical abortion pills sold over the internet). An agenda driven by sexual and reproductive health needs, based on the right to health, must focus on universal access to essential medicines at prices developing countries can afford. We call for greater public investment in essential medicines, expanded production of affordable generic drugs, and the development of broad strategic plans, that include affordable medicines and technologies, for addressing identified public health problems, such as cervical cancer.

    Despite the nutritional significance of sulfur, its influence on biosurfactants production has not been sufficiently studied. We investigated the expression of key biosurfactants production genes, rhlABC, in cultures of Pseudomonas sp. AK6U grown with inorganic or organic sulfur sources. AK6U grew with either inorganic sulfate (MgSO4), dibenzothiophene (DBT), or DBT-sulfone as a sole sulfur source in the presence of glucose as a carbon source. The AK6U cultures produced variable amounts of biosurfactants depending on the utilized sulfur source. Biosurfactants production profile of the DBT cultures was significantly different from that of the DBT-sulfone and inorganic sulfate cultures. The last two cultures were very similar in terms of biosurfactants productivity. Biosurfactants yield in the DBT cultures (1.3 g/L) was higher than that produced by the DBT-sulfone (0.5 g/L) and the inorganic sulfate (0.44 g/L) cultures. Moreover, the surface tension reduction in the DBT cultures (33 mN/m) was much stronger than that measured in the DBT-sulfone (58 mN/m) or inorganic sulfate (54 mN/m) cultures. RT-qPCR revealed variations in the expression levels of the rhlABC genes depending on the sulfur source. The DBT cultures had higher expression levels for the three genes as compared to the DBT-sulfone and inorganic sulfate cultures. There was no significant difference in the expression profiles between the DBT-sulfone and the MgSO4 cultures. The increased expression of rhlC in the DBT cultures is indicative for production of higher amounts of dirhamnolipids compared to the DBT-sulfone and inorganic sulfate cultures. The gene expression results were in good agreement with the biosurfactants production yields and surface tension measurements. The sulfur source mediates a fine-tuned mechanism of transcriptional regulation of biosurfactants production genes. Our findings can have an impact on industrial production of biosurfactants and other biotechnological processes like

The effect in vivois still limited to Indonesia. Purpose: This research was aimed to validate the activity of PMD in increasingcaspase-3 expression and apoptosis in Balb/c mice, induced by Benzo(apyrene (BaP. Methods: A posttest control group was implemented and used by 40 Balb/c mice at the age of 1-2 weeks, with the body weight of 20-30 g. The tumor induction was administered to the mice using BaP. The animals were randomized into two groups called the control group and the PMD treatment group, the latter of which was given a dosage of 50mg. Lung tumor growth was assessed through surgery at week 8, 17, and 26. The results of caspase-3expression and apoptotic index from IHC-TUNEL staining were analyzed using Kruskal-Wallis, Mann-Whitney, One-way ANOVA, and Post hoc test LSD with significant levels of p<α (0,05.This research was approved by Ethical Clearance. Results: Oral administration of 50mg PMD significantly increased caspase-3 expression and apoptotic index in the treatment group animals at weeks 8, 17, and 26. Carcinogenesis incidence in the control group were respectively found at2,32±0,26 and 3,93±0,46 at weeks 8 and 26, while those of the treatment group were 1,88±0,38 and 0,88±0,22 (p=0,001. The apoptotic index in the control group was0,00±0,00 at 8 weeksand0,92+0,22at 26 weeks, whereas the indexes of the treatment group were 1,12±0,71 and 2,02±1,05 (p=0,001. In the control group, the caspase-3 expression at weeks 8 and 26 were 0,28±0,17 and 0,56±0,16, while those in the treatment group were 0,60±0,14 at week 8 and 2,52±0,33 at week 26 (p=0,001. Conclusion: The treatment of PMD effectively induced cell apoptosis in the Balb/c mice via up- regulation of the caspase-3 expression, thereby increasing the apoptotic index. This shows that PMD has anticancer

Intentando na circulação e no uso do PISA, na Bélgica, Escócia, França, Hungria, Portugal e Roménia, procuramos demonstrar que o PISA se afirma como um KRT, provando a relação circular entre conhecimento e política, dado que, como instrumento de política, produz conhecimento e, como instrumento científico, produz política.This text focuses on the study of a KRT (Knowledgebased Regulation Tool, within the wider framework of the new modes of regulation in education, and use of instruments in public action. The world economy is gradually more knowledge-based. Knowledge emerges as a tool for policy-making and for regulating social actors, and legitimating the political decision-making. We choose the OECD's Program for International Student Assessment (PISA as an example of a KRT. The article is based on six case-studies, with interviews and document analysis. Our goal was to study the circulation and use of PISA, in Belgium, Scotland, France, Hungary, Portugal and Romania, trying to show that PISA is indeed a KRT, thus proving the circular relationship between knowledge and policy, because as a policy instrument it produces knowledge, and as a scientific tool it produces policy.

  19. Strained Compromises?

    DEFF Research Database (Denmark)

    Ibsen, Christian Lyhne

    The Danish version of flexicurity is not only about a balance between labour market flexibility and social security. Arguably, it is also series of more or less stable underlying compromises between social partners about the main mechanisms and aims of labour market regulation which – supposedly...... – should be focused on employment rather than jobs and competition on quality rather than on labour costs. However, most studies on Danish flexicurity have been carried out under favourable economic conditions with social partners almost naturally agreeing to the merits of the model – at least in principle...

    Full Text Available In view of the recent negotiations on the highly anticipated Free Trade Agreements to which the EU shall be party ('e.g.' CETA and TTIP, assessing the extent to which the EU can regulate intellectual property rights in its external relations seems relevant. Two recent cases of the Court of Justice of the EU have reversed its landmark decision in Opinion 1/94, in which intellectual property regulation was almost entirely excluded from the EU’s exclusive competence in trade matters. Firstly, in the 'Daiichi Sankyo' case, the Court elaborated upon the EU’s explicit external competence in the field of intellectual property. This explicit competence is provided for by Article 207 TFEU on the common commercial policy, which allows the EU to conclude agreements concerning the ‘commercial aspects of intellectual property’. In the 'Broadcasting Rights' case, the Court founded its decision on the EU’s implied competence to conclude international agreements, as provided for by Article 3(2 TFEU. Considering the outcome of these two judgments, the Court seems to grant the EU a wide scope of action with regard to intellectual property rights. As a consequence, questions arise with regard to the post-Lisbon era role that is left for the Member States in the field of intellectual property. Therefore, the aim of this article is to outline the scope of the EU’s exclusivity in IP matters and to highlight the borders.

    Full Text Available Background: As designated points of entry (PoEs play a critical role in preventing the transmission of international public health risks, huge efforts have been invested in Taiwan to improve the core capacities specified in the International Health Regulations 2005 (IHR 2005. This article reviews how Taiwan strengthened the core capacities at the Taoyuan International Airport (TIA and the Port of Kaohsiung (PoK by applying a new, practicable model. Design: An IHR PoE program was initiated for implementing the IHR core capacities at designated PoEs. The main methods of this program were 1 identifying the designated PoEs according to the pre-determined criteria, 2 identifying the competent authority for each health measure, 3 building a close collaborative relationship between stakeholders from the central and PoE level, 4 designing three stages of systematic assessment using the assessment tool published by the World Health Organization (WHO, and 5 undertaking action plans targeting the gaps identified by the assessments. Results: Results of the self-assessment, preliminary external assessment, and follow-up external assessment revealed a continuous progressive trend at the TIA (86, 91, and 100%, respectively, and at the PoK (77, 97, and 99.9%, respectively. The results of the follow-up external assessment indicated that both these designated PoEs already conformed to the IHR requirements. These achievements were highly associated with strong collaboration, continuous empowerment, efficient resource integration, and sustained commitments. Conclusions: Considering that many countries had requested for an extension on the deadline to fulfill the IHR 2005 core capacity requirements, Taiwan's experiences can be a source of learning for countries striving to fully implement these requirements. Further, in order to broaden the scope of public health protection into promoting global security, Taiwan will keep its commitments on multisectoral cooperation

    Full Text Available Abstract The international community continues to define common strategic themes of actions to improve global partnership and international collaborations in order to protect our populations. The International Health Regulations (IHR[2005] offer one of these strategic themes whereby World Health Organization (WHO Member States and global partners engaged in biosecurity, biosurveillance and public health can define commonalities and leverage their respective missions and resources to optimize interventions. The U.S. Defense Threat Reduction Agency’s Cooperative Biologica Engagement Program (CBEP works with partner countries across clinical, veterinary, epidemiological, and laboratory communities to enhance national disease surveillance, detection, diagnostic, and reporting capabilities. CBEP, like many other capacity building programs, has wrestled with ways to improve partner country buy-in and ownership and to develop sustainable solutions that impact integrated disease surveillance outcomes. Designing successful implementation strategies represents a complex and challenging exercise and requires robust and transparent collaboration at the country level. To address this challenge, the Laboratory Systems Development Branch of the U.S. Centers for Disease Control and Prevention (CDC and CBEP have partnered to create a set of tools that brings together key leadership of the surveillance system into a deliberate system design process. This process takes into account strengths and limitations of the existing system, how the components inter-connect and relate to one another, and how they can be systematically refined within the local context. The planning tools encourage cross-disciplinary thinking, critical evaluation and analysis of existing capabilities, and discussions across organizational and departmental lines toward a shared course of action and purpose. The underlying concepts and methodology of these tools are presented here.

  4. A novel bioassay to evaluate the potential of Beauveria bassiana strain NI8 and the insect growth regulator novaluron against Lygus lineolaris on a non-autoclaved solid artificial diet

    Abstract A non-autoclaved solid diet was used to evaluate the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) strain NI8 and the insect growth regulator novaluron (Diamond® 0.83EC insecticide) for control of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae). The diet was composed of toasted wheat germ, ground lima bean meal, soy flour, yolk of chicken eggs, inhibitor, and agar. It was prepared in one step by blending the ingredients in boiling water. The diet was used to bioassay L. lineolaris from the second instar to the adult stage. Fourth and fifth instars and adults of L. lineolaris were more susceptible than second and third instars to infection by B. bassiana , whereas second, third, and fourth instars had higher mortality than fifth instars 10 days after exposure to novaluron. No effects on longevity were observed in adults treated with novaluron when compared with the control, but longevity was significantly different from that of adults exposed to B. bassiana . Adults of L. lineolaris were maintained for over a month without changing the diet. The non-autoclaved diet is semi-liquid before it cools, which facilitates the mechanics of diet packaging similar to food packaging or lepidopteran diet preparation. This solid artificial diet for Lygus bugs provides improved research capacity for studying the ecology and susceptibility of Lygus spp. to a number of different control agents, including beneficial organisms, insect pathogens, and insecticidal toxins being developed for transgenic technologies.

    Full Text Available For more than ten years (since 2004 the Republic of Lithuania is a member of the EU and is realizing its economic and trade relations with other foreign countries, and regulating customs duties according to the requirements of the EU Common Commercial Policy. However, in the recent years foreign trade (in particular - exports of goods remained one of the main factors which increased an economic growth (recovery in the Republic of Lithuania after the global economic crisis of the world, which began in 2008. In this context, the search for new markets and expansion of trade relations with new trade partners in Asia became essential in order to diversify the structure of the national economy and avoid dependence on traditional trade partners, such as Russia. Taking into account this strategic goal, the article seeks to answer a question whether an existing foreign trade regulation system ensures the status of Lithuania as an attractive partner of foreign trade with East Asian countries (Taiwan, Hong Kong, South Korea and Singapore and what regulatory instruments (customs duty rules and procedures should be used on the national level to ensure cooperation with these countries. In order to answer this problematic question, the first chapter of the article overviews general tendencies in Lithuanian foreign trade with the countries of East Asia, while the second chapter is dedicated to describe regulatory regime for import customs duties on the national level (in line with the major provisions of the EU Common Commercial Policy. The practical problems and obstacles to international trade are presented in the third chapter and are illustrated by the examples of case law, which was formed in disputes relating to the decisions and actions of Lithuanian national customs authorities for the period from 1 May, 2004 (since entry to the EU.

    The World Health Organization (WHO) has emphasized that aging of the population is inextricably linked to many other global public health issues, such as universal health coverage, non-communicable diseases, and disability. However, Alzheimer's Disease International (ADI) estimates that 46.8 million elderly people worldwide were living with dementia in 2015. Alzheimer's disease (AD), the most common form of dementia, is one of the most common neurodegenerative diseases and is the main cause of cognitive impairment. AD will affect 5-7 out of every 100 older adults who are age 60 years or over. In response to the serious challenge posed by AD, governments are expected to play an important role in the prevention, diagnosis, and treatment of AD. As specific examples, i ) the Japanese Government has instituted and supported regulations to encourage the development of AD drugs in order to accelerate research and development of innovative drugs; ii ) the United States Government has cooperated with multiple partners such as non-governmental organizations in the response to AD; iii ) Chinese governmental measures have standardized clinical diagnosis and treatment as part of the response to AD, including eligible patients, diagnostic criteria, therapeutic schedules, drug selection, and required inspections; iv ) with political support from member governments, the European Union has issued guidelines and conducted clinical studies on medicines for the treatment of AD in order to ascertain the various stages of the disease and the relevance of biomarkers. AD is an intractable disease, so different countries need to share clinic trial information and cooperate in the conduct of those trials. International cooperation will play a key role in the response to other intractable and rare diseases.

    Laboratory is one of the core capacities that countries must develop for the implementation of the International Health Regulations (IHR[2005]) since laboratory services play a major role in all the key processes of detection, assessment, response, notification, and monitoring of events. While developed countries easily adapt their well-organized routine laboratory services, resource-limited countries need considerable capacity building as many gaps still exist. In this paper, we discuss some of the efforts made by the African Field Epidemiology Network (AFENET) in supporting laboratory capacity development in the Africa region. The efforts range from promoting graduate level training programs to building advanced technical, managerial and leadership skills to in-service short course training for peripheral laboratory staff. A number of specific projects focus on external quality assurance, basic laboratory information systems, strengthening laboratory management towards accreditation, equipment calibration, harmonization of training materials, networking and provision of pre-packaged laboratory kits to support outbreak investigation. Available evidence indicates a positive effect of these efforts on laboratory capacity in the region. However, many opportunities exist, especially to support the roll-out of these projects as well as attending to some additional critical areas such as biosafety and biosecuity. We conclude that AFENET's approach of strengthening national and sub-national systems provide a model that could be adopted in resource-limited settings such as sub-Saharan Africa.

    Full Text Available Most human Q fever infections originate from small ruminants. By contrast, highly prevalent shedding of Coxiella (C. burnetii by bovine milk rarely results in human disease. We hypothesized that primary bovine and human monocyte-derived macrophages (MDM represent a suitable in vitro model for the identification of strain-specific virulence properties at the cellular level. Twelve different C. burnetii strains were selected to represent different host species and multiple loci variable number of tandem repeat analysis (MLVA genotypes. Infection efficiency and replication of C. burnetii were monitored by cell culture re-titration and qPCR. Expression of immunoregulatory factors after MDM infection was measured by qRT-PCR and flow cytometry. Invasion, replication and MDM response differed between C. burnetii strains but not between MDMs of the two hosts. Strains isolated from ruminants were less well internalized than isolates from humans and rodents. Internalization of MLVA group I strains was lower compared to other genogroups. Replication efficacy of C. burnetii in MDM ranged from low (MLVA group III to high (MLVA group IV. Infected human and bovine MDM responded with a principal up-regulation of pro-inflammatory cytokines such as IL-1β, IL-12, and TNF-α. However, MLVA group IV strains induced a pronounced host response whereas infection with group I strains resulted in a milder response. C. burnetii infection marginally affected polarization of MDM. Only one C. burnetii strain of MLVA group IV caused a substantial up-regulation of activation markers (CD40, CD80 on the surface of bovine and human MDM. The study showed that replication of C. burnetii in MDM and the subsequent host cell response is genotype-specific rather than being determined by the host species pointing to a clear distinction in C. burnetii virulence between the genetic groups.

    Alzheimer's disease (AD) is one of the most common neurodegenerative diseases. Recently, increasing evidence suggests that intracellular β-amyloid protein (Aβ) alone plays a pivotal role in the progression of AD. Therefore, understanding the signaling pathway and proteins that control Aβ internalization may provide new insight for regulating Aβ levels. In the present study, the regulation of Aβ internalization by p38 mitogen-activated protein kinases (MAPK) through low-density lipoprotein receptor-related protein 1 (LRP1) was analyzed in vivo. The data derived from this investigation revealed that Aβ1-42 were internalized by neurons and astrocytes in mouse brain, and were largely deposited in mitochondria and lysosomes, with some also being found in the endoplasmic reticulum. Aβ1-42-LRP1 complex was formed during Aβ1-42 internalization, and the p38 MAPK signaling pathway was activated by Aβ1-42 via LRP1. Aβ1-42 and LRP1 were co- localized in the cells of parietal cortex and hippocampus. Furthermore, the level of LRP1-mRNA and LRP1 protein involved in Aβ1-42 internalization in mouse brain. The results of this investigation demonstrated that Aβ1-42 induced an LRP1-dependent pathway that related to the activation of p38 MAPK resulting in internalization of Aβ1-42. These results provide evidence supporting a key role for the p38 MAPK signaling pathway which is involved in the regulation of Aβ1-42 internalization in the parietal cortex and hippocampus of mouse through LRP1 in vivo.

    Current risk stratification of internal carotid artery plaques based on diameter-reducing percentage stenosis may be unreliable because ischemic stroke results from plaque disruption with atheroembolization. Biomechanical forces acting on the plaque may render it vulnerable to rupture. The feasibility of ultrasound-based quantification of plaque displacement and strain induced by hemodynamic forces and their relationship to high-risk plaques have not been determined. We studied the feasibility and reliability of carotid plaque strain measurement from clinical B-mode ultrasound images and the relationship of strain to high-risk plaque morphology. We analyzed carotid ultrasound B-mode cine loops obtained in patients with asymptomatic ≥50% stenosis during routine clinical scanning. Optical flow methods were used to quantify plaque motion and shear strain during the cardiac cycle. The magnitude (maximum absolute shear strain rate [MASSR]) and variability (entropy of shear strain rate [ESSR] and variance of shear strain rate [VSSR]) of strain were combined into a composite shear strain index (SSI), which was assessed for interscan repeatability and correlated with plaque echolucency. Nineteen patients (mean age, 70 years) constituting 36 plaques underwent imaging; 37% of patients (n = 7) showed high strain (SSI ≥0.5; MASSR, 2.2; ESSR, 39.7; VSSR, 0.03) in their plaques; the remaining clustered into a low-strain group (SSI routine B-mode imaging using clinical ultrasound machines. High plaque strain correlates with known high-risk echolucent morphology. Strain measurement can complement identification of patients at high risk for plaque disruption and stroke.

    In a small diameter piping, stresses are generated due to internal fluid or pump vibrations especially around the welding parts. Authors have successfully developed a pipe strain sensor which is able to measure such stresses. Unlike conventional methods using strain gages and adhesive bond, the sensor can measure the strain without putting adhesive bond on the piping surface. However, the strain sensor can provide measurements with a level of accuracy equivalent to that of conventional method using strain gages and adhesive bond. Accordingly, the strain sensor can significantly reduce the working time without any loss of the measurement accuracy. (author)

    Full Text Available The infection of Cryptococcus neoformans is acquired through the inhalation of desiccated yeast cells and basidiospores originated from the environment, particularly from bird's droppings and decaying wood. Three environmental strains of C. neoformans originated from bird droppings (H4, S48B and S68B and C. neoformans reference clinical strain (H99 were used for intranasal infection in C57BL/6 mice. We showed that the H99 strain demonstrated higher virulence compared to H4, S48B and S68B strains. To examine if gene expression contributed to the different degree of virulence among these strains, a genome-wide microarray study was performed to inspect the transcriptomic profiles of all four strains. Our results revealed that out of 7,419 genes (22,257 probes examined, 65 genes were significantly up-or down-regulated in H99 versus H4, S48B and S68B strains. The up-regulated genes in H99 strain include Hydroxymethylglutaryl-CoA synthase (MVA1, Mitochondrial matrix factor 1 (MMF1, Bud-site-selection protein 8 (BUD8, High affinity glucose transporter 3 (SNF3 and Rho GTPase-activating protein 2 (RGA2. Pathway annotation using DAVID bioinformatics resource showed that metal ion binding and sugar transmembrane transporter activity pathways were highly expressed in the H99 strain. We suggest that the genes and pathways identified may possibly play crucial roles in the fungal pathogenesis.

    This study used a 2-stage questionnaire survey to explore whether self-regulation by withholding negative emotions (SRWNE) affects mental health and examines further whether cultural fit can moderate the relationship between SRWNE and mental health. The 2-stage studies used data collected from 405 (time 1) and 313 (time 2) full-time staff employed by private and public enterprises in Taiwan. The author tested hypotheses through the use of hierarchical multiple regression. The results showed that controlled SRWNE through external regulation and introjected regulation is significantly associated positively with somatic symptoms, anxiety and insomnia, social dysfunction, and severe depression, whereas autonomous SRWNE through identified regulation is significantly associated negatively with anxiety and insomnia, and social dysfunction. In addition, this study also found that cultural fit may moderate the relationship between SRWNE or introjected regulation and identified regulation and the mental health indicators. © 2012 APJPH.

    On July 1, 2011, the Accreditation Council for Graduate Medical Education implemented further restrictions of its 2003 regulations on duty hours and supervision. It remains unclear if the 2003 regulations improved trainee well-being or patient safety. To determine the effects of the 2011 Accreditation Council for Graduate Medical Education duty hour regulations compared with the 2003 regulations concerning sleep duration, trainee education, continuity of patient care, and perceived quality of care among internal medicine trainees. Crossover study design in an academic research setting. Medical house staff. General medical teams were randomly assigned using a sealed-envelope draw to an experimental model or a control model. We randomly assigned 4 medical house staff teams (43 interns) using a 3-month crossover design to a 2003-compliant model of every fourth night overnight call (control) with 30-hour duty limits or to one of two 2011-compliant models of every fifth night overnight call (Q5) or a night float schedule (NF), both with 16-hour duty limits. We measured sleep duration using actigraphy and used admission volumes, educational opportunities, the number of handoffs, and satisfaction surveys to assess trainee education, continuity of patient care, and perceived quality of care. RESULTS The study included 560 control, 420 Q5, and 140 NF days that interns worked and 834 hospital admissions. Compared with controls, interns on NF slept longer during the on call period (mean, 5.1 vs 8.3 hours; P = .003), and interns on Q5 slept longer during the postcall period (mean, 7.5 vs 10.2 hours; P = .05). However, both the Q5 and NF models increased handoffs, decreased availability for teaching conferences, and reduced intern presence during daytime work hours.

    IgE antibody production in mice of high and low IgE responder phenotypes, respectively, can be appreciably enhanced in magnitude after low-dose whole-body x irradiation. Such enhanced responses, as well as adoptive secondary IgE responses, can be markedly suppressed by passive transfer of CFA-immune serum in low responder strains, but not in high responder strains. The studies presented here demonstrate that the suppressive activity of CFA-immune serum on IgE antibody production is strain specific. This is true even in reciprocal combinations of low IgE responder SJL and C57BL/6 mice, in which it was shown that serum capable of suppressing mice of the isologous strain was ineffective in diminishing IgE antibody production in the other low responder strain. Absence of suppressive activity in CFA-immune sera obtained from H-2 haplotypes while sharing many similarities in the background genome and, conversely, effective suppressive activity of H-2 congenic donor sera when H-2-identities between donor and recipient mice existed, strongly suggested a role, at least in part, of H-2 genes in dictating the strain specificity of such suppressive activity. Additional experiments provided evidence for a possible role of macrophages in catabolism of the active molecules in CFA-immune sera. These observations, together with those presented in the preceding paper, may provide valuable insight toward successful development of appropriate manipulations that could ultimately convert high IgE responder individuals into low responders

    Gonorrhea may become untreatable, and new treatment options are essential. We investigated the in vitro activity of the first fluoroketolide, solithromycin. Clinical Neisseria gonorrhoeae isolates and reference strains (n = 246), including the two extensively drug-resistant strains H041 and F89 and additional isolates with clinical cephalosporin resistance and multidrug resistance, were examined. The activity of solithromycin was mainly superior to that of other antimicrobials (n = 10) currently or previously recommended for gonorrhea treatment. Solithromycin might be an effective treatment option for gonorrhea. PMID:22354296

    2015-04-01

    We present a genetic characterization of 65 isolates of Saccharomyces uvarum isolated from wineries in New Zealand, along with the complete nucleotide sequence of a single sulfite-tolerant isolate. The genome of the New Zealand isolate averaged 99.85% nucleotide identity to CBS7001, the previously sequenced strain of S. uvarum. However, three genomic segments (37-87 kb) showed 10% nucleotide divergence from CBS7001 but 99% identity to Saccharomyces eubayanus. We conclude that these three segments appear to have been introgressed from that species. The nucleotide sequence of the internal transcribed spacer (ITS) region from other New Zealand isolates were also very similar to that of CBS7001, and hybrids showed complete genetic compatibility for some strains, with tetrads giving four viable progeny that showed 2:2 segregations of marker genes. Some strains showed high tolerance to sulfite, with genetic analysis indicating linkage of this trait to the transcription factor FZF1, but not to SSU1, the sulfite efflux pump that it regulates in order to confer sulfite tolerance in Saccharomyces cerevisiae. The fermentation characteristics of selected strains of S. uvarum showed exceptionally good cold fermentation characteristics, superior to the best commercially available strains of S. cerevisiae.

    2012-06-01

    Herpes simplex virus type 1 (HSV-1) strain KOS has been extensively used in many studies to examine HSV-1 replication, gene expression, and pathogenesis. Notably, strain KOS is known to be less pathogenic than the first sequenced genome of HSV-1, strain 17. To understand the genotypic differences between KOS and other phenotypically distinct strains of HSV-1, we sequenced the viral genome of strain KOS. When comparing strain KOS to strain 17, there are at least 1,024 small nucleotide polymorphisms (SNPs) and 172 insertions/deletions (indels). The polymorphisms observed in the KOS genome will likely provide insights into the genes, their protein products, and the cis elements that regulate the biology of this HSV-1 strain.

    Although increased caregiver strain is often found among family caregivers of individuals with autism spectrum disorder, it is still unclear as to how different types of strain relate to amount and types of caregiving across the lifespan. The present study examined different types of strain (i.e. subjective internalized strain, subjective externalized strain, and objective strain) and how such strain relates to the amount of caregiving responsibilities. Data was collected via online survey from a sample of 193 family caregivers of individuals with ASD from the United States, Canada, and the Republic of Ireland. Participants completed measures of strain and caregiving responsibilities, as well as coping, demographics, and services needed and received by the individual with ASD. Caregivers reported higher levels of objective strain than subjective, and caregiving responsibility was related to objective and subjective internalized strain. Coping style was strongly correlated with all types of strain, and unmet service needs were significantly related to objective and subjective internalized strain. Caregiving behaviors were only related to objective strain. The present results indicate that, although caregiving responsibility is related to objective and subjective internalized strain, the relationship is perhaps not as strong as the relationship between coping mechanisms and strain. Future research is needed to understand different types of strain and develop strategies to help caregivers. Copyright © 2017 Elsevier Ltd. All rights reserved.

  9. The Commission’s internal conditions for social re-regulation: Market efficiency and wider social goals in setting the rules for financial services in Europe

    Directory of Open Access Journals (Sweden)

    Miriam Hartlapp

    2013-06-01

    Full Text Available The European Union is often considered as a prime example of a liberal regulatory state. We argue, however, that being limited to the regulatory policy does not prevent the European Commission from pursuing political aims going beyond market efficiency. We draw up two ideal-type perspectives of market regulation – being either efficiency or equality enhancing – that differ systematically in terms of rationale, degree of intervention, patterns of stakeholder access and conflict within the regulator. We trace these aspects in three financial services initiatives on the registration and supervision of reinsurers, equal treatment in financial services and the regulation of consumer credit. Our analyses suggest that there is scope for equality-enhancing re-regulation when proactive agents proceed decidedly on the basis of social-treaty concerns and frame regulatory beneficiaries as market participants as well as when they seek the redistribution of rights instead of resources.

    Although pulmonary epithelial cells are integral to innate and adaptive immune responses during Mycobacterium tuberculosis infection, global transcriptomic changes in these cells remain largely unknown. Changes in gene expression induced in pulmonary epithelial cells infected with M. tuberculosis F15/LAM4/KZN, F11, F28, Beijing and Unique genotypes were investigated by RNA sequencing (RNA-Seq). The Illumina HiSeq 2000 platform generated 50 bp reads that were mapped to the human genome (Hg19) using Tophat (2.0.10). Differential gene expression induced by the different strains in infected relative to the uninfected cells was quantified and compared using Cufflinks (2.1.0) and MeV (4.0.9), respectively. Gene expression varied among the strains with the total number of genes as follows: F15/LAM4/KZN (1187), Beijing (1252), F11 (1639), F28 (870), Unique (886) and H37Rv (1179). A subset of 292 genes was commonly induced by all strains, where 52 genes were down-regulated while 240 genes were up-regulated. Differentially expressed genes were compared among the strains and the number of induced strain-specific gene signatures were as follows: F15/LAM4/KZN (138), Beijing (52), F11 (255), F28 (55), Unique (186) and H37Rv (125). Strain-specific molecular gene signatures associated with functional pathways were observed only for the Unique and H37Rv strains while certain biological functions may be associated with other strain signatures. This study demonstrated that strains of M. tuberculosis induce differential gene expression and strain-specific molecular signatures in pulmonary epithelial cells. Specific signatures induced by clinical strains of M. tuberculosis can be further explored for novel host-associated biomarkers and adjunctive immunotherapies. Copyright © 2016 Elsevier Ltd.

    2014-01-01

    Full Text Available Analysis and studying of the terrorism in all its facets is a complex entangled problem with less clear legal regulation that it might seem at first glance, especially after its transformation from local phenomenon into a world threat. Hitherto terrorism and actions connected to it have been criminalized by the majority of states. There are in modern criminal law whole systems of rules on criminal liability for terrorism which differs considerably from country to country. Terrorism has been criminalized in numerous international regional and universal antiterrorist legal instruments. The author notes that differences in definitions that are enshrined in them hinders international cooperation in criminal matters with respect to terrorist cases. Difficulties reside in the necessity to meet the dual criminality requirement and in the political offense exception. These difficulties can only be overcome through elaboration of a universally recognized definition of the notion of international terrorism and making it legally binding via its inclusion into a universal convention. The issue of definition of international terrorism is an important part of an efficient mutual assistance among states in fight against this crime. In this article the author accounts of actual ways of tackling by the international community of the issue of criminalization of international terrorism and of factors influencing them.

    This paper intends to compare the Brasilian basic regulation on radiological protection with the new recommendations of ICRP through existent differences. The main difference between the publication 60 and the publication 103 of the ICRP is the changing of concept of protection based on the process by use of practice and intervention concepts, to the protection based on the exposure situation, through the concepts of planned exposure, emergency and existent situation. For adequacy to the Brazilian regulation it is necessary to change its concept of protection and the values of radiation weighing and tissues, up dating of radiation detriments, besides to make clear the concept of environmental radioprotection

    The Rat Genome Database (RGD) ( http://rgd.mcw.edu/) is the premier site for comprehensive data on the different strains of the laboratory rat (Rattus norvegicus). The strain data are collected from various publications, direct submissions from individual researchers, and rat providers worldwide. Rat strain, substrain designation and nomenclature follow the Guidelines for Nomenclature of Mouse and Rat Strains, instituted by the International Committee on Standardized Genetic Nomenclature for Mice. While symbols and names aid in identifying strains correctly, the flat nature of this information prohibits easy search and retrieval, as well as other data mining functions. In order to improve these functionalities, particularly in ontology-based tools, the Rat Strain Ontology (RS) was developed. The Rat Strain Ontology (RS) reflects the breeding history, parental background, and genetic manipulation of rat strains. This controlled vocabulary organizes strains by type: inbred, outbred, chromosome altered, congenic, mutant and so on. In addition, under the chromosome altered category, strains are organized by chromosome, and further by type of manipulations, such as mutant or congenic. This allows users to easily retrieve strains of interest with modifications in specific genomic regions. The ontology was developed using the Open Biological and Biomedical Ontology (OBO) file format, and is organized on the Directed Acyclic Graph (DAG) structure. Rat Strain Ontology IDs are included as part of the strain report (RS: ######). As rat researchers are often unaware of the number of substrains or altered strains within a breeding line, this vocabulary now provides an easy way to retrieve all substrains and accompanying information. Its usefulness is particularly evident in tools such as the PhenoMiner at RGD, where users can now easily retrieve phenotype measurement data for related strains, strains with similar backgrounds or those with similar introgressed regions.

    2005-03-01

    Erwinia chrysanthemi is a phytopathogenic bacterium that causes soft-rot diseases in a broad number of crops. The PhoP-PhoQ system is a key factor in pathogenicity of several bacteria and is involved in the bacterial resistance to different factors, including acid stress. Since E. chrysanthemi is confronted by acid pH during pathogenesis, we have studied the role of this system in the virulence of this bacterium. In this work, we have isolated and characterized the phoP and phoQ mutants of E. chrysanthemi strain 3937. It was found that: (i) they were not altered in their growth at acid pH; (ii) the phoQ mutant showed diminished ability to survive at acid pH; (iii) susceptibility to the antimicrobial peptide thionin was increased; (iv) the virulence of the phoQ mutant was diminished at low and high magnesium concentrations, whereas the virulence of the phoP was diminished only at low magnesium concentrations; (v) in planta Pel activity of both mutant strains was drastically reduced; and (vi) both mutants lagged behind the wild type in their capacity to change the apoplastic pH. These results suggest that the PhoP-PhoQ system plays a role in the virulence of this bacterium in plant tissues, although it does not contribute to bacterial growth at acid pH.

  12. Instrument for measuring fuel cladding strain

    Billeter, T.R.

    1976-01-01

    Development work to provide instrumentation for the continuous measurement of strain of material specimens such as nuclear fuel cladding has shown that a microwave sensor and associated instrumentation hold promise. The cylindrical sensor body enclosing the specimen results in a coaxial resonator absorbing microwave energy at frequencies dependent upon the diameter of the specimen. Diametral changes of a microinch can be resolved with use of the instrumentation. Very reasonable values of elastic strain were measured at 75 0 F and 1000 0 F for an internally pressurized 20 percent C.W. 316 stainless steel specimen simulating nuclear fuel cladding. The instrument also indicated the creep strain of the same specimen pressurized at 6500 psi and at a temperature of 1000 0 F for a period of 700 hours. Although the indicated strain appears greater than actual, the sensor/specimen unit experienced considerable oxidation even though an inert gas purge persisted throughout the test duration. By monitoring at least two modes of resonance, the measured strain was shown to be nearly independent of sensor temperature. To prevent oxidation, a second test was performed in which the specimen/sensor units were contained in an evacuated enclosure. The strain of the two prepressurized specimens as indicated by the microwave instrumentation agreed very closely with pre- and post-test measurements obtained with use of a laser interferometer

    Strain sensors based on individual ZnO piezoelectric fine-wires (PFWs; nanowires, microwires) have been fabricated by a simple, reliable, and cost-effective technique. The electromechanical sensor device consists of a single electrically connected PFW that is placed on the outer surface of a flexible polystyrene (PS) substrate and bonded at its two ends. The entire device is fully packaged by a polydimethylsiloxane (PDMS) thin layer. The PFW has Schottky contacts at its two ends but with distinctly different barrier heights. The I- V characteristic is highly sensitive to strain mainly due to the change in Schottky barrier height (SBH), which scales linear with strain. The change in SBH is suggested owing to the strain induced band structure change and piezoelectric effect. The experimental data can be well-described by the thermionic emission-diffusion model. A gauge factor of as high as 1250 has been demonstrated, which is 25% higher than the best gauge factor demonstrated for carbon nanotubes. The strain sensor developed here has applications in strain and stress measurements in cell biology, biomedical sciences, MEMS devices, structure monitoring, and more.

    Lipid rafts, plasma membrane microdomains, are important for cell survival signaling and cholesterol is a critical lipid component for lipid raft integrity and function. DHA is known to have poor affinity for cholesterol and it influences lipid rafts. Here, we investigated a mechanism underlying the anti-cancer effects of DHA using a human breast cancer cell line, MDA-MB-231. We found that DHA decreased cell surface levels of lipid rafts via their internalization, which was partially reversed by cholesterol addition. With DHA treatment, caveolin-1, a marker for rafts, and EGFR were colocalized with LAMP-1, a lysosomal marker, in a cholesterol-dependent manner, indicating that DHA induces raft fusion with lysosomes. DHA not only displaced several raft-associated onco-proteins, including EGFR, Hsp90, Akt, and Src, from the rafts but also decreased total levels of those proteins via multiple pathways, including the proteasomal and lysosomal pathways, thereby decreasing their activities. Hsp90 overexpression maintained its client proteins, EGFR and Akt, and attenuated DHA-induced cell death. In addition, overexpression of Akt or constitutively active Akt attenuated DHA-induced apoptosis. All these data indicate that the anti-proliferative effect of DHA is mediated by targeting of lipid rafts via decreasing cell surface lipid rafts by their internalization, thereby decreasing raft-associated onco-proteins via proteasomal and lysosomal pathways and decreasing Hsp90 chaperone function. © 2013.

  15. The Cyclic Stress-Strain Curve of Polycrystals

    The internal stresses implied by the Sachs model are estimated for individual PSBs at low plastic strain amplitudes and for homogeneously sheared grains at higher plastic strain amplitudes. The analysis shows that the Sachs model can account semi-quantitatively for experimentally measured cyclic...... stress-strain curves for copper. A similar approximative analysis of the Taylor model cannot account for the data. An interesting feature of the Sachs model is that, although it is assumed that the flow condition is entirely controlled by the PSBs. the predicted cyclic stress-strain curve displays...

  16. Oenorm S 5220-1: monitoring of persons with regard to incorporated radioactive materials. Part 1: General necessity and frequency, a regulation in Austria to protect workers from occupational internal exposure

    2002-01-01

    Intake of non-sealed radioactive material (incorporation) results in people's internal exposure to radioactivity. The basic requirements for incorporation monitoring provided by Part 1 of OENORM S 5220 are intended to contain internal exposures within the limits set forth in EC-Regulation 96/29/Euratom. In particular, it enables the user to determine the internal exposure contribution to the effective dose and to prove at any time that dose limits for equivalent and effective dose have not been exceeded and conditions at the work place have not changed unexpectedly. The OENORM discussed in this paper can be used by the competent authorities as a basis for their determination of the permissibility of the work with non-sealed radioactive material in a certain work place. Based on the OENORM, they can ensure standardized physical radiation protection after incorporation of radionuclides and the calculation of the resulting equivalent and effective doses according to consistent criteria. In the case where the work with non-sealed radioactive material has previously been permitted, the competent authorities can re-evaluate the necessity, the frequency, and the optimal method for incorporation monitoring. Two different kinds of laboratories are envisioned in this standards series to perform the necessary measurements

    1995-03-01

    A murine monoclonal anti-idiotypic antibody (anti-Id), designated B1/1, was produced against an idiotope of a murine antibody (mAb91), which recognizes the epitope, site A, of allergen Lol pIV, one of the major groups of allergens in ryegrass (Lolium perenne) pollen. The ability of B1/1 to modulate the antibody responses to Lol pIV was investigated in murine model systems. In the first system, B1/1-keyhole limpet haemocyanin (KLH) conjugate was administered to treat three different strains of mice (C57BL/6, BALB/c and C3H). In the second and third model systems, a solution of B1/1 in phosphate-buffered saline (PBS) was used to treat syngeneic BALB/c mice at various doses and time intervals, respectively. The treatment with either form of B1/1, administered at doses ranging from 100 ng to 100 micrograms mouse, resulted in a reduction of the levels of the antibodies to Lol pIV. In particular, the level of IgE antibodies to Lol pIV was greatly reduced. The administration of a single intravenous (i.v.) injection of a solution of B1/1 8 weeks prior to the challenge with Lol pIV was still effective in reducing the level of antibodies to the allergen. Moreover, the level of antibodies to Lol pIV that expressed the idiotope mAb91 was also markedly decreased. By contrast, it was observed that the level of antibodies to Lol pIV in mice pretreated with B1/1 in PBS at a dose of 10 ng/mouse increased (albeit slightly) compared to that in mice treated with control mAb. These experimental models lend themselves for investigating the mechanism(s) by which an anti-Id modulates antibody responses to a grass pollen allergen.

    This work presents the strain measurement procedures applied to a compact nuclear reactor steam generator, during a hydrostatic test, using strain gage technology. The test was divided in two steps: primary side test and secondary side test. In the primary side test twelve points for strain measurement using rectangular rosettes, three points (two external and one internal) for temperature measurement using special strain gages and one point for pressure measurement using a pressure transducer were monitored. In the secondary side test 18 points for strain measurement using rectangular rosettes, four points (two external and two internal) for temperature measurement using special strain gages and one point for pressure measurement using a pressure transducer were monitored. The measurement points on both internal and external pressurizer walls were established from pre-calculated stress distribution by means of numerical approach (finite elements modeling). Strain values using a quarter Wheatstone bridge circuit were obtained. Stress values, from experimental strain were determined, and to numerical calculation results were compared. (author)

    1991-01-01

    The present methodology for analysis of structures with random stress strain behavior characterizes the uniaxial stress-strain curve in terms of (1) elastic modulus, (2) engineering stress at initial yield, (3) initial plastic-hardening slope, (4) engineering stress at point of ultimate load, and (5) engineering strain at point of ultimate load. The methodology is incorporated into the Numerical Evaluation of Stochastic Structures Under Stress code for probabilistic structural analysis. The illustrative problem of a thick cylinder under internal pressure, where both the internal pressure and the stress-strain curve are random, is addressed by means of the code. The response value is the cumulative distribution function of the equivalent plastic strain at the inner radius.

    Many foreign countries use separate criteria and regulation procedure according to the categorization of accelerators. In Korea, nuclear and radiation related facilities are divided into 4 groups: 1) Nuclear Reactor and related facilities, 2) Nuclear fuel cycle, nuclear material facilities, 3) Disposal and transport, 4) Radioisotope and radiation generating devices related facilities. All accelerator facilities are categorized as group 4 regardless of their size and type. For facilities that belong to group 1 and 2, Radiation Environmental Impact Assessment Report(REIR) and Preliminary Decommissioning Plan Report(PDPR) should be submitted in construction licensing stage, but there are no rules about above documents for large particle accelerator facilities. Facilities that belong to 4) RI and RG, only two documents of Radiation Safety Report(RSR) and Safety Control Regulation(SCR) are submitted in licensing stage. Because there is no detailed guidelines according to facilities type, properties of each facility are not considered in preparation and licensing process. If we set up the categorization of accelerator facilities, we can expect the effective and safe construction and operation of the large accelerator facilities on the licensing and operation process. Similarly to other counties' criteria, 50 MeV of particle energy could be used as energy band of large particle accelerator. According to categorization, it is necessary to adopt graded licensing stages and separated safety documents. In case of large particle accelerators, it is appropriate to divide the licensing stages to construction and operation. We currently submit PDPR in case of reactor and related facilities, nuclear fuel cycle, and nuclear material facilities. Depending on the energy of particle accelerators, it is necessary to prepare the decontamination and decommissioning for the decrease of current and future burden from radioactive waste.

  2. COEVOLUTION BETWEEN SUPERMASSIVE BLACK HOLES AND BULGES IS NOT VIA INTERNAL FEEDBACK REGULATION BUT BY RATIONED GAS SUPPLY DUE TO ANGULAR MOMENTUM DISTRIBUTION

    We reason that without physical fine-tuning, neither the supermassive black holes (SMBHs) nor the stellar bulges can self-regulate or inter-regulate by driving away already fallen cold gas to produce the observed correlation between them. We suggest an alternative scenario where the observed mass ratios of the SMBHs to bulges reflect the angular momentum distribution of infallen gas such that the mass reaching the stable accretion disk is a small fraction of that reaching the bulge region, averaged over the cosmological timescales. We test this scenario using high-resolution, large-scale cosmological hydrodynamic simulations, without active galactic nucleus (AGN) feedback, assuming the angular momentum distribution of gas landing in the bulge region yields a Mestel disk that is supported by independent simulations resolving the Bondi radii of SMBHs. A mass ratio of 0.1%–0.3% between the very low angular momentum gas that free falls to the subparsec region to accrete to the SMBH and the overall star formation rate is found. This ratio is found to increase with increasing redshift to within a factor of ∼2, suggesting that the SMBH-to-bulge ratio is nearly redshift independent, with a modest increase with redshift, which is a testable prediction. Furthermore, the duty cycle of AGNs with high Eddington ratios is expected to increase significantly with redshift. Finally, while SMBHs and bulges are found to coevolve on ∼30–150 Myr timescales or longer, there is indication that on still smaller timescales, the SMBH accretion and star formation may be less correlated.

National regulatory agencies (NRAs) have incentives to set regulated termination rates above marginal cost to extract rent from international call termination. International network ownership and deregulation are alternatives to combat the incentives of NRAs to distort termination rates.

    The article reports on a challenge to the UK electricity regulator to defend his record by the Coalition for Fair Electricity Regulation (COFFER). The challenge centres on whether the obligation for the regional electric companies (REC) to purchase power from the cheapest source is being enforced. This is related to the wider issue of whether the REC's support of combined-cycle gas turbine (CCGT) is economic. COFFER considers that uneconomic gas-fired power plants are being allowed to displace economic coal-fired stations. Aspects discussed include the background to the dispute and the costs of CCGT and coal fired power generation. 1 fig., 1 tab.

    Existing heat stress risk management guidelines recommended by international standards are not practical for the construction industry which needs site supervision staff to make instant managerial decisions to mitigate heat risks. The ability of the predicted heat strain (PHS) model [ISO 7933 (2004). Ergonomics of the thermal environment analytical determination and interpretation of heat stress using calculation of the predicted heat strain. Geneva: International Standard Organisation] to predict maximum allowable exposure time (D lim) has now enabled development of localized, action-triggering and threshold-based guidelines for implementation by lay frontline staff on construction sites. This article presents a protocol for development of two heat stress management tools by applying the PHS model to its full potential. One of the tools is developed to facilitate managerial decisions on an optimized work-rest regimen for paced work. The other tool is developed to enable workers' self-regulation during self-paced work.

    The plant pathogen Erwinia chrysanthemi produces a variety of factors that have been implicated in its ability to cause soft-rot diseases in various hosts. These include HrpN, a harpin secreted by the Hrp type III secretion system; PelE, one of several major pectate lyase isozymes secreted by the type II system; and PelL, one of several secondary Pels secreted by the type II system. We investigated these factors in E. chrysanthemi EC16 with respect to the effects of medium composition and growth phase on gene expression (as determined with uidA fusions and Northern analyses) and effects on virulence. pelE was induced by polygalacturonic acid, but pelL was not, and hrpN was expressed unexpectedly in nutrient-rich King's medium B and in minimal salts medium at neutral pH. In contrast, the effect of medium composition on hrp expression in E. chrysanthemi CUCPB1237 and 3937 was like that of many other phytopathogenic bacteria in being repressed in complex media and induced in acidic pH minimal medium. Northern blot analysis of hrpN and hrpL expression by the wild-type and hrpL::omegaCmr and hrpS::omegaCmr mutants revealed that hrpN expression was dependent on the HrpL alternative sigma factor, whose expression, in turn, was dependent on the HrpS putative sigma54 enhancer binding protein. The expression of pelE and hrpN increased strongly in late logarithmic growth phase. To test the possible role of quorum sensing in this expression pattern, the expI/expR locus was cloned in Escherichia coli on the basis of its ability to direct production of acyl-homoserine lactone and then used to construct expI mutations in pelE::uidA, pelL::uidA, and hrpN::uidA Erwinia chrysanthemi strains. Mutation of expI had no apparent effect on the growth-phase-dependent expression of hrpN and pelE, or on the virulence of E. chrysanthemi in witloof chicory leaves. Overexpression of hrpN in E. chrysanthemi resulted in approximately 50% reduction of lesion size on chicory leaves without an

At the 21st International Symposium on Microsomes and Drug Oxidations held in Davis, California, USA, in October 2–6, 2016, a number of speakers reported some new findings and ongoing studies on the regulation mechanisms behind variable drug metabolism and toxicity, and discussed potential implications to personalized medications. A considerably insightful overview was provided on genetic and epigenetic regulation of gene expression involved in drug absorption, distribution, metabolism, and excretion (ADME and drug response. Altered drug metabolism and disposition as well as molecular mechanisms among diseased and special populations were presented. In addition, the roles of gut microbiota in drug metabolism and toxicology as well as long non-coding RNAs in liver functions and diseases were discussed. These findings may offer new insights into improved understanding of ADME regulatory mechanisms and advance drug metabolism research.

    Previous genetic association studies of physical activity, in both animal and human models, have been limited in number of subjects and genetically homozygous strains used as well as number of genomic markers available for analysis. Expansion of the available mouse physical activity strain screens and the recently published dense single-nucleotide polymorphism (SNP) map of the mouse genome (approximately 8.3 million SNPs) and associated statistical methods allowed us to construct a more generalizable map of the quantitative trait loci (QTL) associated with physical activity. Specifically, we measured wheel running activity in male and female mice (average age 9 wk) in 41 inbred strains and used activity data from 38 of these strains in a haplotype association mapping analysis to determine QTL associated with activity. As seen previously, there was a large range of activity patterns among the strains, with the highest and lowest strains differing significantly in daily distance run (27.4-fold), duration of activity (23.6-fold), and speed (2.9-fold). On a daily basis, female mice ran further (24%), longer (13%), and faster (11%). Twelve QTL were identified, with three (on Chr. 12, 18, and 19) in both male and female mice, five specific to males, and four specific to females. Eight of the 12 QTL, including the 3 general QTL found for both sexes, fell into intergenic areas. The results of this study further support the findings of a moderate to high heritability of physical activity and add general genomic areas applicable to a large number of mouse strains that can be further mined for candidate genes associated with regulation of physical activity. Additionally, results suggest that potential genetic mechanisms arising from traditional noncoding regions of the genome may be involved in regulation of physical activity.

    Two methyl coenzyme M reductases (MCRs) encoded by the mcr and mrt operons of the hydrogenotrophic methanogen Methanothermobacter thermautotrophicus DeltaH are expressed in response to H(2) availability. In the present study, cis elements and trans-acting factors responsible for the gene expression of MCRs were investigated by using electrophoretic mobility shift assay (EMSA) and affinity particle purification. A survey of their operator regions by EMSA with protein extracts from mrt-expressing cultures restricted them to 46- and 41-bp-long mcr and mrt upstream regions, respectively. Affinity particle purification of DNA-binding proteins conjugated with putative operator regions resulted in the retrieval of a protein attributed to IMP dehydrogenase-related protein VII (IMPDH VII). IMPDH VII is predicted to have a winged helix-turn-helix DNA-binding motif and two cystathionine beta-synthase domains, and it has been suspected to be an energy-sensing module. EMSA with oligonucleotide probes with unusual sequences showed that the binding site of IMPDH VII mostly overlaps the factor B-responsible element-TATA box of the mcr operon. The results presented here suggest that IMPDH VII encoded by MTH126 is a plausible candidate for the transcriptional regulator of the mcr operon in this methanogen.

  14. Cells as strain-cued automata

    Science.gov (United States)

    Cox, Brian N.; Snead, Malcolm L.

    2016-02-01

    We argue in favor of representing living cells as automata and review demonstrations that autonomous cells can form patterns by responding to local variations in the strain fields that arise from their individual or collective motions. An autonomous cell's response to strain stimuli is assumed to be effected by internally-generated, internally-powered forces, which generally move the cell in directions other than those implied by external energy gradients. Evidence of cells acting as strain-cued automata have been inferred from patterns observed in nature and from experiments conducted in vitro. Simulations that mimic particular cases of pattern forming share the idealization that cells are assumed to pass information among themselves solely via mechanical boundary conditions, i.e., the tractions and displacements present at their membranes. This assumption opens three mechanisms for pattern formation in large cell populations: wavelike behavior, kinematic feedback in cell motility that can lead to sliding and rotational patterns, and directed migration during invasions. Wavelike behavior among ameloblast cells during amelogenesis (the formation of dental enamel) has been inferred from enamel microstructure, while strain waves in populations of epithelial cells have been observed in vitro. One hypothesized kinematic feedback mechanism, "enhanced shear motility", accounts successfully for the spontaneous formation of layered patterns during amelogenesis in the mouse incisor. Directed migration is exemplified by a theory of invader cells that sense and respond to the strains they themselves create in the host population as they invade it: analysis shows that the strain fields contain positional information that could aid the formation of cell network structures, stabilizing the slender geometry of branches and helping govern the frequency of branch bifurcation and branch coalescence (the formation of closed networks).

    The article explores and analyses the content of the Council of Europe's Additional Protocol to the Convention on Human Rights and Biomedicine concerning Biomedical Research regarding the standard legal instrument in biomedical research, issued by an international organization with leadership in bioethics. This implies ethics committees are mechanisms of protection of humans in biomedical research and not mere bureaucratic agencies and that a sound inescapable international regulatory framework exists for States to regulate biomedical research. The methodology used focuses on the analysis of the background, the context in which it is made and the nature and scope of the Protocol. It also identifies and analyses the characteristics and functions of ethics committees in biomedical research and, in particular, the information that should be provided to this bodies to develop their functions previously, during and at the end of research projects. This analysis will provide guidelines, suggestions and conclusions for the awareness and training of members of these committees in order to influence the daily practice. This paper may also be of interest to legal practitioners who work in different areas of biomedical research. From this practical perspective, the article examines the legal treatment of the Protocol to meet new challenges and classic issues in research: the treatment of human biological samples, the use of placebos, avoiding double standards, human vulnerability, undue influence and conflicts of interest, among others. Also, from a critical view, this work links the legal responses to develop work procedures that are required for an effective performance of the functions assigned of ethics committees in biomedical research. An existing international legal response that lacks doctrinal standards and provides little support should, however, serve as a guide and standard to develop actions that allow ethics committees -as key bodies for States- to advance in

    Anterior cruciate ligament (ACL) injuries most frequently occur under the large loads associated with a unipedal jump landing involving a cutting or pivoting maneuver. We tested the hypotheses that internal tibial torque would increase the anteromedial (AM) bundle ACL relative strain and strain rate more than would the corresponding external tibial torque under the large impulsive loads associated with such landing maneuvers. Twelve cadaveric female knees [mean (SD) age: 65.0 (10.5) years] were tested. Pretensioned quadriceps, hamstring, and gastrocnemius muscle-tendon unit forces maintained an initial knee flexion angle of 15°. A compound impulsive test load (compression, flexion moment, and internal or external tibial torque) was applied to the distal tibia while recording the 3D knee loads and tibofemoral kinematics. AM-ACL relative strain was measured using a 3 mm DVRT. In this repeated measures experiment, the Wilcoxon signed-rank test was used to test the null hypotheses with p < 0.05 considered significant. The mean (±SD) peak AM-ACL relative strains were 5.4 ± 3.7% and 3.1 ± 2.8% under internal and external tibial torque, respectively. The corresponding mean (± SD) peak AM-ACL strain rates reached 254.4 ± 160.1%/s and 179.4 ± 109.9%/s, respectively. The hypotheses were supported in that the normalized mean peak AM-ACL relative strain and strain rate were 70 and 42% greater under internal than under external tibial torque, respectively (p = 0.023, p = 0.041). We conclude that internal tibial torque is a potent stressor of the ACL because it induces a considerably (70%) larger peak strain in the AM-ACL than does a corresponding external tibial torque.

    Full Text Available Alphaherpesviruses are widespread in the human population, and include herpes simplex virus 1 (HSV-1 and 2, and varicella zoster virus (VZV. These viral pathogens cause epithelial lesions, and then infect the nervous system to cause lifelong latency, reactivation, and spread. A related veterinary herpesvirus, pseudorabies (PRV, causes similar disease in livestock that result in significant economic losses. Vaccines developed for VZV and PRV serve as useful models for the development of an HSV-1 vaccine. We present full genome sequence comparisons of the PRV vaccine strain Bartha, and two virulent PRV isolates, Kaplan and Becker. These genome sequences were determined by high-throughput sequencing and assembly, and present new insights into the attenuation of a mammalian alphaherpesvirus vaccine strain. We find many previously unknown coding differences between PRV Bartha and the virulent strains, including changes to the fusion proteins gH and gB, and over forty other viral proteins. Inter-strain variation in PRV protein sequences is much closer to levels previously observed for HSV-1 than for the highly stable VZV proteome. Almost 20% of the PRV genome contains tandem short sequence repeats (SSRs, a class of nucleic acids motifs whose length-variation has been associated with changes in DNA binding site efficiency, transcriptional regulation, and protein interactions. We find SSRs throughout the herpesvirus family, and provide the first global characterization of SSRs in viruses, both within and between strains. We find SSR length variation between different isolates of PRV and HSV-1, which may provide a new mechanism for phenotypic variation between strains. Finally, we detected a small number of polymorphic bases within each plaque-purified PRV strain, and we characterize the effect of passage and plaque-purification on these polymorphisms. These data add to growing evidence that even plaque-purified stocks of stable DNA viruses exhibit
