    In order to achieve more accurate disease prevention, diagnosis, and treatment, clinical and genetic data need extensive and systematically associated study. As one way to achieve precision medicine, a laboratory information management system (LIMS) can effectively associate clinical data in a macrocosmic aspect and genomic data in a microcosmic aspect. This chapter summarizes the application of the LIMS in a clinical data management and implementation mode. It also discusses the principles of a LIMS in clinical data management, as well as the opportunities and challenges in the context of medical informatics.

  2. LIMS strategy review

    1995-01-01

    The evaluation team found that the LABCORE program has a viable Laboratory Information Management System (LIMS) that will handle the sample tracking and reporting necessary to accomplish the requirements established by the system specifications. The team also found that the LABCORE program has made real accomplishments and that it has been moving in the right direction, for example the phased implementation at the 222-S laboratory. The LABCORE program has many strengths but it also has short comings that need to be addressed. The strengths are that the hardware, software, staff, and the computer and training facilities are all first rate. The shortcomings are that it is missing a strategy outlining the goals which would clearly define when the project implementation has been successfully completed. It also had excessive cost during its acquisition. Specific recommendations are made. As a whole, the evaluation team believes that LABCORE is the system that was specified and will meet the needs of both laboratories, 222-S and the Waste Sampling and Characterization Facility. LABCORE has experienced all the challenges of a new computer system but with continued effort on the part of the LABCORE team and laboratory personnel the system will operate as needed

    2017-01-01

    A Laboratory Information Management System (LIMS) is a databasing software with many built-in tools ideal for handling and documenting most laboratory processes in an accurate and consistent manner, making it an indispensable tool for the modern laboratory. However, a lot of LIMS end users will find that in the performance of analyses that have unique considerations such as standard curves, multiple stages incubations, or logical considerations, a base LIMS distribution may not ideally suit their needs. These considerations bring about the need for extension languages, which can extend the functionality of a LIMS. While these languages do provide the implementation team the functionality required to accommodate these special laboratory analyses, they are usually too complex for the end user to modify to compensate for natural changes in laboratory operations. The LIMS utilized by our laboratory offers a unique and easy-to-use choice for an extension language, one that is already heavily relied upon not only in science but also in most academic and business pursuits: Microsoft Excel. The validity of Microsoft Excel as a pseudo programming language and its usability and versatility as a LIMS extension language will be discussed. The NELAC implications and overall drawbacks of this LIMS configuration will also be discussed.

  6. Balassa-Samuelson Effect in Won/Dollar and Won/Yen Exchange Rates

    Full Text Available This paper examines, using various models including a non-linear one, that the Balassa-Samuelson (BS effect can account for the persistence of deviations from PPP in the long-run movements of won/dollar and won/yen real exchange rates. In test for PPP hypothesis that incorporates the BS effect, using the generalized Johansen' cointegration method, it is found that a cointegration relationship exists between each of won/dollar and won/yen real exchange rate and the productivity variables of two countries. And in test for PPP hypothesis that incorporates other fundamentals such as cumulative current account balance, foreign exchange reserve, terms of trade as well as productivity differentials, using a behavioral equilibrium exchange rate approach, it is found that a cointegration relationship exists between each of won/dollar and won/yen real exchange rate and all of these fundamentals. However, the plus sign of the estimated coefficient of the productivity differentials variable, which means that domestic productivity improvement produces increase in each of won/dollar and won/yen real exchange rate is not coincident with the result that the BS effect expects theoretically. Finally, in test for PPP hypothesis that incorporates the BS effect, using a non-linear STAR model, it is found that the adjustment process in case of won/dollar real exchange rate from the long-run equilibrium level can be adequately explained by a non-linear LSTAR model. But, the evidence of diagnostic statistics, which shows the existence of autocorrelation of the residuals in most of lags, might suggest the inadequacy of LSTAR model specification.

    Short stator linear induction motors, with an iron-backed aluminum sheet reaction rail and powered by a controlled inverter, have been selected as the propulsion system for transit vehicles in an intermediate capacity system (12-20,000 pphpd). The linear induction motor is capable of adhesion independent braking and acceleration levels which permit safe, close headways. In addition, simple control is possible allowing moving block automatic train control. This paper presents a slip frequency control scheme for the LIM. Experimental results for motoring and braking obtained from a test vehicle are also presented. These values are compared with theoretical predictions.

    1987-01-01

    In the late 70's, a refurbishment of the analytical laboratories serving the Materials Division at NASA Lewis Research Center was undertaken. As part of the modernization efforts, a Laboratory Information Management System (LIMS) was to be included. Preliminary studies indicated a custom-designed system as the best choice in order to satisfy all of the requirements. A scaled down version of the original design has been in operation since 1984. The LIMS, a combination of computer hardware, provides the chemical characterization laboratory with an information data base, a report generator, a user interface, and networking capabilities. This paper is an account of the processes involved in designing and implementing that LIMS.

The Ca-2LIM belongs to PLIM and GLIM (XLIM was found highly expressed in floral tissue. Others showed ubiquitous expression pattern with their dominance in stem. Under hormonal and pathogenic conditions these LIMs were found to up-regulate during salicylic acid, abscisic acid and Ascochyta rabiei treatment or infection; and down-regulated in response to jasmonic acid treatment. The findings of this work, particularly in terms of modulation of LIM genes under biotic stress will open up the way to further explore and establish the role of chickpea LIMs in plant defense response.

    This presentation focuses on the steps taken by the Westinghouse Hanford Company to meet an accelerated schedule for configuration and implementation of the MULTI LIMS in a multiple laboratory environment. The Westinghouse Hanford Company purchased the MULTI LIMS Laboratory Information Management System in August, 1993. Hardware delivery began in October, 1993. Less than four months later, the initial configuration was released for use in two Westinghouse Hanford Company laboratories. Several major obstacles were overcome during implementation. These include information gathering for base table loading, user training, acceptance of the new system by users of a legacy system, and hardware configuration issues. In summary, steps needed to be taken to meet the accelerated implementation schedule of the MULTI LIMS at the Hanford Site. The obstacles faced were overcome through the in-depth knowledge and help of the vendor and the dedication and drive of the technical staff

    Changes in the world and United Kingdom markets for nuclear fuels during the 1990s have prompted British Nuclear Fuels (BNFL) to maximise cost effectiveness in its Chemical and Metallurgical Services department. A laboratory information management system (LIMS) was introduced in order to keep records of analytical techniques and equipment up to date by coordinating various computer systems. Wherever possible automated systems have replaced traditional, labour intensive techniques. So successful has the LIMS system been, that the team now hopes to expand into expert systems. (UK)

    Laboratory Information Management Systems (LIMS) are an increasingly important part of modern laboratory infrastructure. As typically very sophisticated software products, LIMS often require considerable resources to select, deploy and maintain. Larger organisations may have access to specialist IT support to assist with requirements elicitation and software customisation, however smaller groups will often have limited IT support to perform the kind of iterative development that can resolve the difficulties that biologists often have when specifying requirements. Translational medicine aims to accelerate the process of treatment discovery by bringing together multiple disciplines to discover new approaches to treating disease, or novel applications of existing treatments. The diverse set of disciplines and complexity of processing procedures involved, especially with the use of high throughput technologies, bring difficulties in customizing a generic LIMS to provide a single system for managing sample related data within a translational medicine research setting, especially where limited IT support is available. We have designed and developed a LIMS, BonsaiLIMS, around a very simple data model that can be easily implemented using a variety of technologies, and can be easily extended as specific requirements dictate. A reference implementation using Oracle 11 g database and the Python framework, Django is presented. By focusing on a minimal feature set and a modular design we have been able to deploy the BonsaiLIMS system very quickly. The benefits to our institute have been the avoidance of the prolonged implementation timescales, budget overruns, scope creep, off-specifications and user fatigue issues that typify many enterprise software implementations.

    Maternal dietary restriction during pregnancy impairs nephron development and results in offspring with fewer nephrons. Cell turnover in the early developing kidney is altered by exposure to maternal dietary restriction and may be regulated by the LIM-kinase family of enzymes. We set out to establish whether disturbance of LIM-kinase activity might play a role in the impairment of nephron formation. E12.5 metanephric kidneys and HK2 cells were grown in culture with the pharmacological LIM-kinase inhibitor BMS5. Organs were injected with DiI, imaged and cell numbers measured over 48h to assess growth. Cells undergoing mitosis were visualised by pH3 labelling. Growth of cultured kidneys reduced to 83% of controls after exposure to BMS5 and final cell number to 25% of control levels after 48h. Whilst control and BMS5 treated organs showed cells undergoing mitosis (100±11 cells/field vs 113±18 cells/field respectively) the proportion in anaphase was considerably diminished with BMS5 treatment (7.8±0.8% vs 0.8±0.6% respectively; Plabelled cells migrated in 100% of control cultures vs 0% BMS5 treated organs. The number of nephrogenic precursor cells appeared depleted in whole organs and formation of new nephrons was blocked by exposure to BMS5. Pharmacological blockade of LIM-kinase function in the early developing kidney results in failure of renal development. This is likely due to prevention of dividing cells from completion of mitosis with their resultant loss. Copyright © 2017 Elsevier Inc. All rights reserved.

    In the cross-border belt between Serbia and Montenegro are located more than one hundred torrential water flows that belong to the Lim River Basin. Under extreme climate events they turned into floods of destructive power and great energy causing enormous damage on the environment and socio-economic development in the wider region of the Western Balkans. In addition, anthropogenic factors influence the land instability, erosion of river beds and loss of topsoil. Consequently, this whole area is affected by pluvial and fluvial erosion of various types and intensity. Terrain on the slopes over 5% is affected by intensive degree of erosion, while strong to medium degree covers 70% of the area. Moreover, in the Lim River Basin were built several hydro-energetic systems and accumulations which may to a certain extent successfully regulate the water regime downstream and to reduce the negative impact on the processes of water erosion. However, siltation of accumulation reduces their useful volume and threatens the basic functions (water reservoirs), especially those ones for water supply, irrigation and energy production that have lost a significant part of the usable volume due to accumulated sediments. Facing the negative impacts of climate change and human activities on the process of land degradation in the Lim River basin imposes urgent need of adequate preventive and protective measures at the local and regional level, which can be effectively applied only through enhanced cross-border cooperation among affected communities in the region. The following set of activities were analyzed to improve the actual management of river catchment: Identifying priorities in the spatial planning, land use and water resources management while respecting the needs of local people and the communities in the cross border region; development of cooperation and partnership between the local population, owners and users of real estate (pastures, agricultural land, forests, fisheries

    As the cost of sequencing continues to fall, smaller groups increasingly initiate and manage larger sequencing projects and take on the complexity of data storage for high volumes of samples. This has created a need for low-cost laboratory information management systems (LIMS) that contain flexible fields to accommodate the unique nature of individual labs. Many labs do not have a dedicated information technology position, so LIMS must also be easy to setup and maintain with minimal technical proficiency. MetaLIMS is a free and open-source web-based application available via GitHub. The focus of MetaLIMS is to store sample metadata prior to sequencing and analysis pipelines. Initially designed for environmental metagenomics labs, in addition to storing generic sample collection information and DNA/RNA processing information, the user can also add fields specific to the user's lab. MetaLIMS can also produce a basic sequencing submission form compatible with the proprietary Clarity LIMS system used by some sequencing facilities. To help ease the technical burden associated with web deployment, MetaLIMS options the use of commercial web hosting combined with MetaLIMS bash scripts for ease of setup. MetaLIMS overcomes key challenges common in LIMS by giving labs access to a low-cost and open-source tool that also has the flexibility to meet individual lab needs and an option for easy deployment. By making the web application open source and hosting it on GitHub, we hope to encourage the community to build upon MetaLIMS, making it more robust and tailored to the needs of more researchers. © The Authors 2017.

    LIM homeobox (Lhx) transcription factors are unique to the animal lineage and have patterning roles during embryonic development in flies, nematodes and vertebrates, with a conserved role in specifying neuronal identity. Though genes of this family have been reported in a sponge and a cnidarian, the expression patterns and functions of the Lhx family during development in non-bilaterian phyla are not known. We identified Lhx genes in two cnidarians and a placozoan and report the expression of Lhx genes during embryonic development in Nematostella and the demosponge Amphimedon. Members of the six major LIM homeobox subfamilies are represented in the genomes of the starlet sea anemone, Nematostella vectensis, and the placozoan Trichoplax adhaerens. The hydrozoan cnidarian, Hydra magnipapillata, has retained four of the six Lhx subfamilies, but apparently lost two others. Only three subfamilies are represented in the haplosclerid demosponge Amphimedon queenslandica. A tandem cluster of three Lhx genes of different subfamilies and a gene containing two LIM domains in the genome of T. adhaerens (an animal without any neurons) indicates that Lhx subfamilies were generated by tandem duplication. This tandem cluster in Trichoplax is likely a remnant of the original chromosomal context in which Lhx subfamilies first appeared. Three of the six Trichoplax Lhx genes are expressed in animals in laboratory culture, as are all Lhx genes in Hydra. Expression patterns of Nematostella Lhx genes correlate with neural territories in larval and juvenile polyp stages. In the aneural demosponge, A. queenslandica, the three Lhx genes are expressed widely during development, including in cells that are associated with the larval photosensory ring. The Lhx family expanded and diversified early in animal evolution, with all six subfamilies already diverged prior to the cnidarian-placozoan-bilaterian last common ancestor.

    The Limb Infrared Monitor of the Stratospheric water vapor channel data analysis has been extended from the 1. mb level (about 48 km) to the .3 mb level (about 60 km) through a radiance averaging procedure and better understanding of systematic errors. The data show H2O mixing ratio peaks near the .5 mb level varying from 4 to 7 ppmv with latitude and season. Above this level the mixing ratio drops off quickly with altitude, but, due to experimental uncertainties, at an uncertain rate. The stratospheric results are virtually the same as determined from the archived LIMS results with a tropical hygropause and enhanced H2O concentration in the lower levels at high winter latitudes.

    This paper presents Leaf LIMS, a flexible laboratory information management system (LIMS) designed to address the complexity of synthetic biology workflows. At the project's inception there was a lack of a LIMS designed specifically to address synthetic biology processes, with most systems focused on either next generation sequencing or biobanks and clinical sample handling. Leaf LIMS implements integrated project, item, and laboratory stock tracking, offering complete sample and construct genealogy, materials and lot tracking, and modular assay data capture. Hence, it enables highly configurable task-based workflows and supports data capture from project inception to completion. As such, in addition to it supporting synthetic biology it is ideal for many laboratory environments with multiple projects and users. The system is deployed as a web application through Docker and is provided under a permissive MIT license. It is freely available for download at https://leaflims.github.io .

    Muscle lim protein (MLP) has long been regarded as a cytosolic and nuclear muscular protein. Here, we show that MLP is also expressed in a subpopulation of adult rat dorsal root ganglia (DRG) neurons in response to axonal injury, while the protein was not detectable in naïve cells. Detailed immunohistochemical analysis of L4/L5 DRG revealed ~3% of MLP-positive neurons 2 days after complete sciatic nerve crush and maximum ~10% after 4-14 days. Similarly, in mixed cultures from cervical, thoracic, lumbar and sacral DRG ~6% of neurons were MLP-positive after 2 days and maximal 17% after 3 days. In both, histological sections and cell cultures, the protein was detected in the cytosol and axons of small diameter cells, while the nucleus remained devoid. Moreover, the vast majority could not be assigned to any of the well characterized canonical DRG subpopulations at 7 days after nerve injury. However, further analysis in cell culture revealed that the largest population of MLP expressing cells originated from non-peptidergic IB4-positive nociceptive neurons, which lose their ability to bind the lectin upon axotomy. Thus, MLP is mostly expressed in a subset of axotomized nociceptive neurons and can be used as a novel marker for this population of cells.

  10. The diversification of the LIM superclass at the base of the metazoa increased subcellular complexity and promoted multicellular specialization.

    Full Text Available Throughout evolution, the LIM domain has been deployed in many different domain configurations, which has led to the formation of a large and distinct group of proteins. LIM proteins are involved in relaying stimuli received at the cell surface to the nucleus in order to regulate cell structure, motility, and division. Despite their fundamental roles in cellular processes and human disease, little is known about the evolution of the LIM superclass.We have identified and characterized all known LIM domain-containing proteins in six metazoans and three non-metazoans. In addition, we performed a phylogenetic analysis on all LIM domains and, in the process, have identified a number of novel non-LIM domains and motifs in each of these proteins. Based on these results, we have formalized a classification system for LIM proteins, provided reasonable timing for class and family origin events; and identified lineage-specific loss events. Our analysis is the first detailed description of the full set of LIM proteins from the non-bilaterian species examined in this study.Six of the 14 LIM classes originated in the stem lineage of the Metazoa. The expansion of the LIM superclass at the base of the Metazoa undoubtedly contributed to the increase in subcellular complexity required for the transition from a unicellular to multicellular lifestyle and, as such, was a critically important event in the history of animal multicellularity.

    Full Text Available In this paper, we have examined the short-run movement of the won/dollar exchange rate using information obtained from the inter-bank market in Korea. First, we constructed the hourly measure of excess demand for dollar and used it as a proxy for the trading pattern of market participants. To construct this time series, we relied on the bid and ask won/dollar exchange rates collected on the two-minute interval. We then estimated the structural VAR model consisting of the actually observed won/dollar exchange rate and the proxied trading pattern of market participants to see if private information, as opposed to public information, is relevant for explaining the hourly movement of the won/dollar exchange rate. Private information is found to account for more 30% of hourly variations of the won/dollar exchange rate. Next, we constructed the trading pattern of market participants on a daily basis using the same data set employed to build the hourly measure. We then examined whether private information is useful for predicting the daily won/dollar exchange rate movement. We found that the forecast model using both private and public information reduces out-of-sample forecast errors of an alternative model relying only on public information by 20~25%. Also, the out-of-sample forecast of the model using both private and public information is found to be more accurate than the random walk model.

    In this paper, the magnetic properties of LiM n2O4 nanorods with an average diameter of ˜100 nm and length of ˜1 μ m are investigated. The temperature dependences of dc and ac susceptibility measurements show that LiM n2O4 nanorods experience multiple magnetic phase transitions upon cooling, i.e., paramagnetic (PM), antiferromagnetic (AFM), canted antiferromagnetic (CAFM), and cluster spin glass (SG). The coexistence between a long-range ordered AFM phase due to a M n4 +-M n4 + interaction and a cluster SG phase originating from frozen AFM clusters at low temperature in LiM n2O4 nanorods is elucidated. Field-cooled hysteresis loops (FC loops) and magnetic training effect (TE) measurements confirm the presence of an exchange-bias (EB) effect in LiM n2O4 nanorods below the Néel temperature (TN˜60 K ) . Furthermore, by analyzing the TE, we conclude that the observed EB effect originates completely from an exchange coupling interaction at the interface between the AFM and cluster SG states. A phenomenological model based on phase coexistence is proposed to interpret the origin of the EB effect below 60 K in the present compound. In turn, the appearance of the EB effect further supports the coexistence of AFM order along with a cluster SG state in LiM n2O4 nanorods.

    In this study, we compared the Tang repair technique with the 6-strand modified Lim-Tsai repair technique under cyclic testing conditions. Twenty fresh-frozen porcine flexor tendons were randomized into 2 groups for repair with either the modified Lim-Tsai or the Tang technique using Supramid 4-0 core sutures and Ethilon 6-0 epitendinous running suture. The repaired tendons were subjected to 2 stage cyclic loading. The survival rate and gap formation at the repair site were recorded. Tendons repaired by the Tang technique achieved an 80% survival rate. None of the modified Lim-Tsai repairs survived. The mean gap formed at the end of 1000 cycles was 1.09 mm in the Tang repairs compared with 4.15 mm in the modified Lim-Tsai repairs. The Tang repair is biomechanically stronger than the modified Lim-Tsai repair under cyclic loading. The Tang repair technique may exhibit a higher tolerance for active mobilization after surgery with less propensity for gap formation. Copyright © 2018 American Society for Surgery of the Hand.

    Life-science laboratories make increasing use of Next Generation Sequencing (NGS) for studying bio-macromolecules and their interactions. Array-based methods for measuring gene expression or protein-DNA interactions are being replaced by RNA-Seq and ChIP-Seq. Sequencing is generally performed by specialized facilities that have to keep track of sequencing requests, trace samples, ensure quality and make data available according to predefined privileges. An integrated tool helps to troubleshoot problems, to maintain a high quality standard, to reduce time and costs. Commercial and non-commercial tools called LIMS (Laboratory Information Management Systems) are available for this purpose. However, they often come at prohibitive cost and/or lack the flexibility and scalability needed to adjust seamlessly to the frequently changing protocols employed. In order to manage the flow of sequencing data produced at the Genomic Unit of the Italian Institute of Technology (IIT), we developed SMITH (Sequencing Machine Information Tracking and Handling). SMITH is a web application with a MySQL server at the backend. Wet-lab scientists of the Centre for Genomic Science and database experts from the Politecnico of Milan in the context of a Genomic Data Model Project developed SMITH. The data base schema stores all the information of an NGS experiment, including the descriptions of all protocols and algorithms used in the process. Notably, an attribute-value table allows associating an unconstrained textual description to each sample and all the data produced afterwards. This method permits the creation of metadata that can be used to search the database for specific files as well as for statistical analyses. SMITH runs automatically and limits direct human interaction mainly to administrative tasks.

    Changes in the world and United Kingdom markets for nuclear fuels during the 1990s have prompted British Nuclear Fuels (BNFL) to maximise cost effectiveness in its Chemical and Metallurgical Services department. A laboratory information management system (LIMS) was introduced in order to keep records of analytical techniques and equipment up to date by coordinating various computer systems. Wherever possible automated systems have replaced traditional, labour intensive techniques. So successful has the LIMS system been, that the team now hopes to expand into expert systems. (UK).

    2009-01-01

    This report describes the quality of the Nimbus 7 Limb Infrared Monitor of the Stratosphere (LIMS) water vapor (H2O) profiles of 1978/79 that were processed with a Version 6 (V6) algorithm and archived in 2002. The V6 profiles incorporate a better knowledge of the instrument attitude for the LIMS measurements along its orbits, leading to improvements for its temperature profiles and for the registration of its water vapor radiances with pressure. As a result, the LIMS V6 zonal-mean distributions of H2O exhibit better hemispheric symmetry than was the case from the original Version 5 (V5) dataset that was archived in 1982. Estimates of the precision and accuracy of the V6 H2O profiles are developed and provided. Individual profiles have a precision of order 5% and an estimated accuracy of about 19% at 3 hPa, 14% at 10 hPa, and 26% at 50 hPa. Profile segments within about 2 km of the tropopause are often affected by emissions from clouds that appear in the finite field-of-view of the detector for the LIMS H2O channel. Zonally-averaged distributions of the LIMS V6 H2O are compared with those from the more recent Microwave Limb Sounder (MLS) satellite experiment for November, February, and May of 2004/2005. The patterns and values of their respective distributions are similar in many respects. Effects of a strengthened Brewer-Dobson circulation are indicated in the MLS distributions of the recent decade versus those of LIMS from 1978/79. A tropical tape recorder signal is present in the 7-month time series of LIMS V6 H2O with lowest values in February 1979, and the estimated, annually-averaged "entry-level" H2O is 3.5 to 3.8 ppmv. It is judged that this historic LIMS water vapor dataset is of good quality for studies of the near global-scale chemistry and transport for pressure levels from 3 hPa to about 70 to 100 hPa.

    2014-08-27

    Large clinical genomics studies using next generation DNA sequencing require the ability to select and track samples from a large population of patients through many experimental steps. With the number of clinical genome sequencing studies increasing, it is critical to maintain adequate laboratory information management systems to manage the thousands of patient samples that are subject to this type of genetic analysis. To meet the needs of clinical population studies using genome sequencing, we developed a web-based laboratory information management system (LIMS) with a flexible configuration that is adaptable to continuously evolving experimental protocols of next generation DNA sequencing technologies. Our system is referred to as MendeLIMS, is easily implemented with open source tools and is also highly configurable and extensible. MendeLIMS has been invaluable in the management of our clinical genome sequencing studies. We maintain a publicly available demonstration version of the application for evaluation purposes at http://mendelims.stanford.edu. MendeLIMS is programmed in Ruby on Rails (RoR) and accesses data stored in SQL-compliant relational databases. Software is freely available for non-commercial use at http://dna-discovery.stanford.edu/software/mendelims/.

  20. Mutation in LIM2 Is Responsible for Autosomal Recessive Congenital Cataracts.

    Bushra Irum

    Full Text Available To identify the molecular basis of non-syndromic autosomal recessive congenital cataracts (arCC in a consanguineous family.All family members participating in the study received a comprehensive ophthalmic examination to determine their ocular phenotype and contributed a blood sample, from which genomic DNA was extracted. Available medical records and interviews with the family were used to compile the medical history of the family. The symptomatic history of the individuals exhibiting cataracts was confirmed by slit-lamp biomicroscopy. A genome-wide linkage analysis was performed to localize the disease interval. The candidate gene, LIM2 (lens intrinsic membrane protein 2, was sequenced bi-directionally to identify the disease-causing mutation. The physical changes caused by the mutation were analyzed in silico through homology modeling, mutation and bioinformatic algorithms, and evolutionary conservation databases. The physiological importance of LIM2 to ocular development was assessed in vivo by real-time expression analysis of Lim2 in a mouse model.Ophthalmic examination confirmed the diagnosis of nuclear cataracts in the affected members of the family; the inheritance pattern and cataract development in early infancy indicated arCC. Genome-wide linkage analysis localized the critical interval to chromosome 19q with a two-point logarithm of odds (LOD score of 3.25. Bidirectional sequencing identified a novel missense mutation, c.233G>A (p.G78D in LIM2. This mutation segregated with the disease phenotype and was absent in 192 ethnically matched control chromosomes. In silico analysis predicted lower hydropathicity and hydrophobicity but higher polarity of the mutant LIM2-encoded protein (MP19 compared to the wild-type. Moreover, these analyses predicted that the mutation would disrupt the secondary structure of a transmembrane domain of MP19.

    The objectives of this case report are as follows: to describe the process of establishing a national laboratory information management system (LIMS) program for clinical and public health laboratories in Vietnam; to evaluate the outcomes and lessons learned; and to present a model for sustainability based on the program outcomes that could be applied to diverse laboratory programs. This case report comprises a review of program documentation and records, including planning and budgetary records of the donor, monthly reports from the implementer, direct observation, and ad-hoc field reports from technical advisors and governmental agencies. Additional data on program efficacy and user acceptance were collected from routine monitoring of laboratory policies and operational practices. LIMS software was implemented at 38 hospital, public health and HIV testing laboratories in Vietnam. This LIMS was accepted by users and program managers as a useful tool to support laboratory processes. Implementation cost per laboratory and average duration of deployment decreased over time, and project stakeholders initiated transition of financing (from the donor to local institutions) and of system maintenance functions (from the implementer to governmental and site-level staff). Collaboration between the implementer in Vietnam and the global LIMS user community was strongly established, and knowledge was successfully transferred to staff within Vietnam. Implementing open-sourced LIMS with local development and support was a feasible approach towards establishing a sustainable laboratory informatics program that met the needs of health laboratories in Vietnam. Further effort to institutionalize IT support capacity within key government agencies is ongoing. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  3. Characterization of upstream sequences of the LIM2 gene that bind developmentally regulated and lens-specific proteins

    2004-01-01

    During lens development, lens epithelial cells differentiate into fiber cells. To date, four major lens fiber cell intrinsic membrane proteins (MIP) ranging in size from 70 kD to 19 kD have been characterized. The second most abundant lens fiber cell intrinsic membrane protein is MP19. This protein probably is involved with lens cell communication and relates with cataractogenesis. The aim of this research is to characterize upstream sequences of the MP19 (also called LIM2) gene that bind developmentally regulated and lens-specific proteins. We have used the gel mobility assays and corresponding competition experiments to identify and characterize cis elements within approximately 500 bases of LIM2 upstream sequences. Our studies locate the positions of some cis elements, including a "CA" repeat, a methylation Hha I island, an FnuD II site, an Ap1 and an Ap2 consensus sequences, and identify some specific cis elements which relate to lens-specific transcription of LIM2. Our experiments also preliminarily identify trans factors which bind to specific cis elements of the LIM2 promoter and/or regulate transcription of LIM2. We conclude that developmental regulation and coordination of the MP 19 gene in ocular lens fiber cells is controlled by the presence of specific cis elements that bind regulatory trans factors that affect LIM2 gene expression. DNA methylation is one mechanism of controlling LIM2 gene expression during lens development.

  5. Won-Buddhism and a Great Turning in Civilization: The Role of Religion

    Directory of Open Access Journals (Sweden)

    Paik Nak-chung

    2017-03-01

    Full Text Available Addressing the theme of a great turning in civilization, this essay focuses on the Korean religion Won-Buddhism with its founding motto, “With this Great Opening of matter, let there be a Great Opening of spirit.” Both its doctrine and practice arguably possess great potential. Unlike the traditional Buddhist view of enlightenment, Won-Buddhism’s “Great Opening of spirit” starts from a specific diagnosis of the current time as an age of “Great Opening of matter” and proposes a double project of at once adapting to and overcoming modernity. In this way, it carries on the tradition of Korea’s indigenous religious movements since the mid-nineteenth century, but by combining that strain with Buddhism as its core doctrine, it achieves a fuller global significance than its predecessors. The essay examines Roberto Unger’s The Religion of the Future for both parallels and divergences, sympathizing with Unger’s emphasis on a religious revolution, but finding his thought essentially confined within the limits of Western metaphysics. Martin Heidegger is brought in to elucidate this point, as is Karl Marx, for comparison and contrast with Won-Buddhism’s diagnosis of and response to modernity. In closing, the essay takes up two Won-Buddhist agendas that are also of global concern: gender equality and the “church and state” relation.

    2004-06-01

    This work describes a comprehensive characterization of the factors controlling the floatability of free gold from flotation test using reagents (collectors) at plant concentration levels. A relationship between the collectors loadings on gold particles and their surface composition has been established. The findings of this study show that silver activates gold flotation and there is a strong correlation between the surface concentration of silver and the loading of certain collectors. The organic surface analysis was done by ToF-SIMS while the inorganic surface analysis was carried out by time-of-flight laser ionization mass spectrometry (ToF-LIMS). The developed testing protocol based on ToF-LIMS and ToF-SIMS complementary surface analysis allows for optimization of the flotation scheme and hence improved gold recovery.

    An increasing number of research laboratories and core analytical facilities around the world are developing high throughput metabolomic analytical and data processing pipelines that are capable of handling hundreds to thousands of individual samples per year, often over multiple projects, collaborations and sample types. At present, there are no Laboratory Information Management Systems (LIMS) that are specifically tailored for metabolomics laboratories that are capable of tracking samples and associated metadata from the beginning to the end of an experiment, including data processing and archiving, and which are also suitable for use in large institutional core facilities or multi-laboratory consortia as well as single laboratory environments. Here we present MASTR-MS, a downloadable and installable LIMS solution that can be deployed either within a single laboratory or used to link workflows across a multisite network. It comprises a Node Management System that can be used to link and manage projects across one or multiple collaborating laboratories; a User Management System which defines different user groups and privileges of users; a Quote Management System where client quotes are managed; a Project Management System in which metadata is stored and all aspects of project management, including experimental setup, sample tracking and instrument analysis, are defined, and a Data Management System that allows the automatic capture and storage of raw and processed data from the analytical instruments to the LIMS. MASTR-MS is a comprehensive LIMS solution specifically designed for metabolomics. It captures the entire lifecycle of a sample starting from project and experiment design to sample analysis, data capture and storage. It acts as an electronic notebook, facilitating project management within a single laboratory or a multi-node collaborative environment. This software is being developed in close consultation with members of the metabolomics research

  11. Insights into the molecular evolution of the PDZ/LIM family and identification of a novel conserved protein motif.

    Directory of Open Access Journals (Sweden)

    Aartjan J W Te Velthuis

    Full Text Available The PDZ and LIM domain-containing protein family is encoded by a diverse group of genes whose phylogeny has currently not been analyzed. In mammals, ten genes are found that encode both a PDZ- and one or several LIM-domains. These genes are: ALP, RIL, Elfin (CLP36, Mystique, Enigma (LMP-1, Enigma homologue (ENH, ZASP (Cypher, Oracle, LMO7 and the two LIM domain kinases (LIMK1 and LIMK2. As conventional alignment and phylogenetic procedures of full-length sequences fell short of elucidating the evolutionary history of these genes, we started to analyze the PDZ and LIM domain sequences themselves. Using information from most sequenced eukaryotic lineages, our phylogenetic analysis is based on full-length cDNA-, EST-derived- and genomic- PDZ and LIM domain sequences of over 25 species, ranging from yeast to humans. Plant and protozoan homologs were not found. Our phylogenetic analysis identifies a number of domain duplication and rearrangement events, and shows a single convergent event during evolution of the PDZ/LIM family. Further, we describe the separation of the ALP and Enigma subfamilies in lower vertebrates and identify a novel consensus motif, which we call 'ALP-like motif' (AM. This motif is highly-conserved between ALP subfamily proteins of diverse organisms. We used here a combinatorial approach to define the relation of the PDZ and LIM domain encoding genes and to reconstruct their phylogeny. This analysis allowed us to classify the PDZ/LIM family and to suggest a meaningful model for the molecular evolution of the diverse gene architectures found in this multi-domain family.

    Reversion-induced LIM protein (RIL) is a member of the ALP (actinin-associated LIM protein) subfamily of the PDZ/LIM protein family. RIL serves as an adaptor protein and seems to regulate cytoskeletons. Immunoblotting suggested that RIL is concentrated in the astrocytes in the central nervous system. We then examined the expression and localization of RIL in the rat central nervous system and compared it with that of water channel aquaporin 4 (AQP4). RIL was concentrated in the cells of ependyma lining the ventricles in the brain and the central canal in the spinal cord. In most parts of the central nervous system, RIL was expressed in the astrocytes that expressed AQP4. Double-labeling studies showed that RIL was concentrated in the cytoplasm of astrocytes where glial fibrillary acidic protein was enriched as well as in the AQP4-enriched regions such as the endfeet or glia limitans. RIL was also present in some neurons such as Purkinje cells in the cerebellum and some neurons in the brain stem. Differential expression of RIL suggests that it may be involved in the regulation of the central nervous system

    In order to identify novel genes enriched in adult heart, we performed a subtractive hybridization for genes expressed in mouse heart but not in skeletal muscle. We identified two alternative splicing variants of a novel PDZ-LIM domain protein, which we named Oracle. Both variants contain a PDZ domain at the amino-terminus and three LIM domains at the carboxy-terminus. Highest homology of Oracle was found with the human and rat enigma proteins in the PDZ domain (62 and 61%, respectively) and in the LIM domains (60 and 69%, respectively). By Northern hybridization analysis, we showed that expression is highest in adult mouse heart, low in skeletal muscle and undetectable in other adult mouse tissues. In situ hybridization in mouse embryos confirmed and extended these data by showing high expression of Oracle mRNA in atrial and ventricular myocardial cells from E8.5. From E9.5 low expression of Oracle mRNA was detectable in myotomes. These data suggest a role for Oracle in the early development and function of heart and skeletal muscle.

    The Hippo pathway controls organ growth and is implicated in cancer development. Whether and how Hippo pathway activity is limited to sustain or initiate cell growth when needed is not understood. The members of the AJUBA family of LIM proteins are negative regulators of the Hippo pathway. In mammalian epithelial cells, we found that AJUBA LIM proteins limit Hippo regulation of YAP, in proliferating cells only, by sequestering a cytosolic Hippo kinase complex in which LATS kinase is inhibited. At the plasma membranes of growth-arrested cells, AJUBA LIM proteins do not inhibit or associate with the Hippo kinase complex. The ability of AJUBA LIM proteins to inhibit YAP regulation by Hippo and to associate with the kinase complex directly correlate with their capacity to limit Hippo signaling during Drosophila wing development. AJUBA LIM proteins did not influence YAP activity in response to cell-extrinsic or cell-intrinsic mechanical signals. Thus, AJUBA LIM proteins limit Hippo pathway activity in contexts where cell proliferation is needed. Copyright © 2016 Jagannathan et al.

    A Laboratory Information Management System (LIMS) was used to manage the laboratory data and support planning and field activities as part of the response to the equine influenza outbreak in Australia in 2007. The database structure of the LIMS and the system configurations that were made to best handle the laboratory implications of the disease response are discussed. The operational aspects of the LIMS and the related procedures used at the laboratory to process the increased sample throughput are reviewed, as is the interaction of the LIMS with other corporate systems used in the management of the response. Outcomes from this tailored configuration and operation of the LIMS resulted in effective provision and control of the laboratory and laboratory information aspects of the response. The extent and immediate availability of the information provided from the LIMS was critical to some of the activities of key operatives involved in controlling the response. © 2011 The Authors.

    Many biological laboratories that deal with genomic samples are facing the problem of sample tracking, both for pure laboratory management and for efficiency. Our laboratory exploits PCR techniques and Next Generation Sequencing (NGS) methods to perform high-throughput integration site monitoring in different clinical trials and scientific projects. Because of the huge amount of samples that we process every year, which result in hundreds of millions of sequencing reads, we need to standardize data management and tracking systems, building up a scalable and flexible structure with web-based interfaces, which are usually called Laboratory Information Management System (LIMS). We started collecting end-users' requirements, composed of desired functionalities of the system and Graphical User Interfaces (GUI), and then we evaluated available tools that could address our requirements, spanning from pure LIMS to Content Management Systems (CMS) up to enterprise information systems. Our analysis identified ADempiere ERP, an open source Enterprise Resource Planning written in Java J2EE, as the best software that also natively implements some highly desirable technological advances, such as the high usability and modularity that grants high use-case flexibility and software scalability for custom solutions. We extended and customized ADempiere ERP to fulfil LIMS requirements and we developed adLIMS. It has been validated by our end-users verifying functionalities and GUIs through test cases for PCRs samples and pre-sequencing data and it is currently in use in our laboratories. adLIMS implements authorization and authentication policies, allowing multiple users management and roles definition that enables specific permissions, operations and data views to each user. For example, adLIMS allows creating sample sheets from stored data using available exporting operations. This simplicity and process standardization may avoid manual errors and information backtracking, features

    Full Text Available A microarray is a principal technology in molecular biology. It generates thousands of expressions of genotypes at once. Typically, a microarray experiment contains many kinds of information, such as gene names, sequences, expression profiles, scanned images, and annotation. So, the organization and analysis of vast amounts of data are required. Microarray LIMS (Laboratory Information Management System provides data management, search, and basic analysis. Recently, microarray joint researches, such as the skeletal system disease and anti-cancer medicine have been widely conducted. This research requires data sharing among laboratories within the joint research group. In this paper, we introduce a web based microarray LIMS, SMILE (Small and solid MIcroarray Lims for Experimenters, especially for shared data management. The data sharing function of SMILE is based on Friend-to-Friend (F2F, which is based on anonymous P2P (Peer-to-Peer, in which people connect directly with their “friends”. It only allows its friends to exchange data directly using IP addresses or digital signatures you trust. In SMILE, there are two types of friends: “service provider”, which provides data, and “client”, which is provided with data. So, the service provider provides shared data only to its clients. SMILE provides useful functions for microarray experiments, such as variant data management, image analysis, normalization, system management, project schedule management, and shared data management. Moreover, it connections with two systems: ArrayMall for analyzing microarray images and GENAW for constructing a genetic network. SMILE is available on http://neobio.cs.pusan.ac.kr:8080/smile.

    Full Text Available This thesis analyzed the feature and different points of the changing of the exchange rate of Korea won against US dollar, then discussed the direction of the completion of Korea exchange rate system. The prediction result of the model GARCH which vividly shows the phenomenon of the auto-regression of the exchange rate has indicated the level of the exchange rate yesterday could explain the circumstance of the change of exchange rate today. Meanwhile, the policy of the US exchange rate will affect the exchange rate of Korea won against US dollar and the volatility of foreign exchange rate. In the present situation of Korean economy in which the liberalization of capital and the independence of the central bank has been established, the choosing range of the exchange system could only be completely changeable exchange rate system or exchange rate system of multilateral arrangement like Europe. However, in terms of the condition of the world economy, the introduction of the latter system is too early. There is an idea that under the changeable exchange rate system which is the only choice, it is the right time to activate the main body of private economy, the financial derivatives market in which the exchange risk could be trade-off. Government should work on and create a policy that would be able to satisfy the expectations of the market participants.

    PCNA is a multi-functional protein that is involved in various nuclear events. Here we show that PCNA participates in events occurring during early meiotic prophase. Analysis of protein-protein interactions using surface plasmon resonance indicates that Coprinus cinereus PCNA (CoPCNA) specifically interacts with a meiotic specific RecA-like factor, C. cinereus Lim15/Dmc1 (CoLim15) in vitro. The binding efficiency increases with addition of Mg 2+ ions, while ATP inhibits the interaction. Co-immunoprecipitation experiments indicate that the CoLim15 protein interacts with the CoPCNA protein in vitro and in the cell extracts. Despite the interaction between these two factors, no enhancement of CoLim15-dependent strand transfer activity by CoPCNA was found in vitro. We propose that the interaction between Lim15/Dmc1 and PCNA mediates the recombination-associated DNA synthesis during meiosis

    Full Text Available Open loop VVVF control has the disadvantage of low output torque when working at low frequency and poor speed precision at different load conditions.Various performance-improving schemes have been proposed for the basic VVVF control by compensating slips occurring in the low frequency range and slips caused by changing loads. Numerous papers have been published on the close loop speed control of rotary induction motor. In this paper a close loop speed control with VVVF control and slip regulation has been implemented for LIM based conveyor belt test Rig which compensates the disadvantages of traditional Volts/Hz control. SIMULINK results are presented to validate the effectiveness of proposed scheme.

    Nutrient profiling aims to classify or rank foods according to their nutritional composition to assist policies aimed at improving the nutritional quality of foods and diets. The present paper reviews a French approach of nutrient profiling by describing the SAIN,LIM system and its evolution from its early draft to the simplified nutrition labelling system (SENS) algorithm. Considered in 2010 by WHO as the 'French model' of nutrient profiling, SAIN,LIM classifies foods into four classes based on two scores: a nutrient density score (NDS) called SAIN and a score of nutrients to limit called LIM, and one threshold on each score. The system was first developed by the French Food Standard Agency in 2008 in response to the European regulation on nutrition and health claims (European Commission (EC) 1924/2006) to determine foods that may be eligible for bearing claims. Recently, the European regulation (EC 1169/2011) on the provision of food information to consumers allowed simplified nutrition labelling to facilitate consumer information and help them make fully informed choices. In that context, the SAIN,LIM was adapted to obtain the SENS algorithm, a system able to rank foods for simplified nutrition labelling. The implementation of the algorithm followed a step-by-step, systematic, transparent and logical process where shortcomings of the SAIN,LIM were addressed by integrating specificities of food categories in the SENS, reducing the number of nutrients, ordering the four classes and introducing European reference intakes. Through the French example, this review shows how an existing nutrient profiling system can be specifically adapted to support public health nutrition policies.

    Hiroyuki Nakagawa

    Full Text Available Lasp-2 binds to actin filaments and concentrates in the actin bundles of filopodia and lamellipodia in neural cells and focal adhesions in fibroblastic cells. Lasp-2 has three structural regions: a LIM domain, a nebulin-repeat region, and an SH3 domain; however, the region(s responsible for its interactions with actin filaments and focal adhesions are still unclear. In this study, we revealed that the N-terminal fragment from the LIM domain to the first nebulin-repeat module (LIM-n1 retained actin-binding activity and showed a similar subcellular localization to full-length lasp-2 in neural cells. The LIM domain fragment did not interact with actin filaments or localize to actin filament bundles. In contrast, LIM-n1 showed a clear subcellular localization to filopodial actin bundles. Although truncation of the LIM domain caused the loss of F-actin binding activity and the accumulation of filopodial actin bundles, these truncated fragments localized to focal adhesions. These results suggest that lasp-2 interactions with actin filaments are mediated through the cooperation of the LIM domain and the first nebulin-repeat module in vitro and in vivo. Actin filament binding activity may be a major contributor to the subcellular localization of lasp-2 to filopodia but is not crucial for lasp-2 recruitment to focal adhesions.

    Full Text Available It has been proposed that a novel maglev transport system uses both of the attractive force and thrust force of the Linear Induction Motor (LIM. In our proposal, these two forces will be controlled by two different frequency components. One of the frequency components is synchronous with the motor speed (fm. Another frequency component is drive frequency (fd. Our proposed system enables the independent and simultaneous control of the attractive and thrust force of LIM. Each value of the attractive and the thrust force generated by fm and fd must be identified in order to design that LIM control system. For these purpose, a disc-shaped LIM has been developed as an experimental equipment. The force profiles, especially around zero slip, have been analyzed under experimental conditions.

The writers concerned in this paper are K.S Maniam, Shirley Lim and Jhumpa Lahiri. All these writers have nationalities not of their motherland, but somehow, their writings are usually immersed with the thoughts and culture of their motherland.

    Arash Shaban-Nejad

    2009-01-01

    Full Text Available Requirement volatility is an issue in software engineering in general, and in Web-based clinical applications in particular, which often originates from an incomplete knowledge of the domain of interest. With advances in the health science, many features and functionalities need to be added to, or removed from, existing software applications in the biomedical domain. At the same time, the increasing complexity of biomedical systems makes them more difficult to understand, and consequently it is more difficult to define their requirements, which contributes considerably to their volatility. In this paper, we present a novel agent-based approach for analyzing and managing volatile and dynamic requirements in an ontology-driven laboratory information management system (LIMS designed for Web-based case reporting in medical mycology. The proposed framework is empowered with ontologies and formalized using category theory to provide a deep and common understanding of the functional and nonfunctional requirement hierarchies and their interrelations, and to trace the effects of a change on the conceptual framework.

    LIM kinase 1 (LIMK1) activity is essential for cell migration and cell cycle progression. Little is known about LIMK1 expression and function in mammalian oocytes. In the present study we assessed LIMK1 protein expression, subcellular distribution and function during mouse oocyte meiosis. Western blot analysis revealed high and stable expression of LIMK1 from the germinal vesicle (GV) to MII stage. In contrast, activated LIMK1 (i.e. LIMK1 phosphorylated at threonine 508 (pLIMK1 Thr508 )) was only detected after GV breakdown, with levels increasing gradually to peak at MI and MII. Immunofluorescence showed pLIMK1 Thr508 was colocalised with the microtubule organising centre (MTOC) components pericentrin and γ-tubulin at the spindle poles. A direct interaction between γ-tubulin and pLIMK1 Thr508 was confirmed by co-immunoprecipitation. LIMK inhibition with 1μM BMS3 damaged MTOC protein localisation to spindle poles, undermined the formation and positioning of functional MTOC and thus disrupted spindle formation and chromosome alignment. These effects were phenocopied by microinjection of LIMK1 antibody into mouse oocytes. In summary, the data demonstrate that LIMK activity is essential for MTOC organisation and distribution and so bipolar spindle formation and maintenance in mouse oocytes.

  15. The LIM-only protein FHL2 attenuates lung inflammation during bleomycin-induced fibrosis.

    Directory of Open Access Journals (Sweden)

    Abdulaleem Alnajar

    Full Text Available Fibrogenesis is usually initiated when regenerative processes have failed and/or chronic inflammation occurs. It is characterised by the activation of tissue fibroblasts and dysregulated synthesis of extracellular matrix proteins. FHL2 (four-and-a-half LIM domain protein 2 is a scaffolding protein that interacts with numerous cellular proteins, regulating signalling cascades and gene transcription. It is involved in tissue remodelling and tumour progression. Recent data suggest that FHL2 might support fibrogenesis by maintaining the transcriptional expression of alpha smooth muscle actin and the excessive synthesis and assembly of matrix proteins in activated fibroblasts. Here, we present evidence that FHL2 does not promote bleomycin-induced lung fibrosis, but rather suppresses this process by attenuating lung inflammation. Loss of FHL2 results in increased expression of the pro-inflammatory matrix protein tenascin C and downregulation of the macrophage activating C-type lectin receptor DC-SIGN. Consequently, FHL2 knockout mice developed a severe and long-lasting lung pathology following bleomycin administration due to enhanced expression of tenascin C and impaired activation of inflammation-resolving macrophages.

    The reliability and accuracy of isotopic data can be improved by utilizing database software to (i) store information about samples, (ii) store the results of mass spectrometric isotope-ratio analyses of samples, (iii) calculate analytical results using standardized algorithms stored in a database, (iv) normalize stable isotopic data to international scales using isotopic reference materials, and (v) generate multi-sheet paper templates for convenient sample loading of automated mass-spectrometer sample preparation manifolds. Such a database program is presented herein. Major benefits of this system include (i) an increase in laboratory efficiency, (ii) reduction in the use of paper, (iii) reduction in workload due to the elimination or reduction of retyping of data by laboratory personnel, and (iv) decreased errors in data reported to sample submitters. Such a database provides a complete record of when and how often laboratory reference materials have been analyzed and provides a record of what correction factors have been used through time. It provides an audit trail for stable isotope laboratories. Since the original publication of the manual for LIMS for Light Stable Isotopes, the isotopes 3 H, 3 He, and 14 C, and the chlorofluorocarbons (CFCs), CFC-11, CFC-12, and CFC-113, have been added to this program.

    In Canada, three objectives are identified that must be met in order to improve the climate of public opinion in favor of nuclear energy. They are: to establish credibility and trust in the industry; to establish acceptance and confidence in products and, increase the level of public support for the nuclear industry. A specific target group was also identified: men and women leaders of opinion in and 18 years old. A lot of research was conducted that led to establishing of four major strategies which could help achieving general objective over a time of 3 years: to open an on-going dialogue with the Canadian public; to introduce and familiarize the Canadian public with specific applications of nuclear energy; to present specific facts about nuclear energy; to monitor the results. Advertising is only one of the tools of this program. In all advertising efforts one should ensure that the public understands that this is the process of information not advocacy. This is considered as extremely important. It is believed that public confidence and acceptance can be won by advertising. Because of the actual Energy Dependency of Canada, ranking second in the world in electricity consumption per capita, and because Canada can no longer, rely on traditional great degree on damming large rivers to produce electricity, it is the duty of nuclear industry to provide information to the Canadian public in order for them to know all the facts when they are asked to choose between different forms of energy to produce electricity

    Preparation of two-dimensional (2D) heterostructures is important not only fundamentally, but also technologically for applications in electronics and optoelectronics. Herein, we report a facile colloidal method for the synthesis of WOn -WX2 (n=2.7, 2.9; X=S, Se) heterostructures by sulfurization or selenization of WOn nanomaterials. The WOn -WX2 heterostructures are composed of WO2.9 nanoparticles (NPs) or WO2.7 nanowires (NWs) grown together with single- or few-layer WX2 nanosheets (NSs). As a proof-of-concept application, the WOn -WX2 heterostructures are used as the anode interfacial buffer layer for green quantum dot light-emitting diodes (QLEDs). The QLED prepared with WO2.9 NP-WSe2 NS heterostructures achieves external quantum efficiency (EQE) of 8.53 %. To our knowledge, this is the highest efficiency in the reported green QLEDs using inorganic materials as the hole injection layer.

    Full Text Available Abstract Background Biodiversity databases serve the important role of highlighting species-level diversity from defined geographical regions. Databases that are specially designed to accommodate the types of data gathered during regional surveys are valuable in allowing full data access and display to researchers not directly involved with the project, while serving as a Laboratory Information Management System (LIMS. The Hawaiian Freshwater Algal Database, or HfwADB, was modified from the Hawaiian Algal Database to showcase non-marine algal specimens collected from the Hawaiian Archipelago by accommodating the additional level of organization required for samples including multiple species. Description The Hawaiian Freshwater Algal Database is a comprehensive and searchable database containing photographs and micrographs of samples and collection sites, geo-referenced collecting information, taxonomic data and standardized DNA sequence data. All data for individual samples are linked through unique 10-digit accession numbers (“Isolate Accession”, the first five of which correspond to the collection site (“Environmental Accession”. Users can search online for sample information by accession number, various levels of taxonomy, habitat or collection site. HfwADB is hosted at the University of Hawaii, and was made publicly accessible in October 2011. At the present time the database houses data for over 2,825 samples of non-marine algae from 1,786 collection sites from the Hawaiian Archipelago. These samples include cyanobacteria, red and green algae and diatoms, as well as lesser representation from some other algal lineages. Conclusions HfwADB is a digital repository that acts as a Laboratory Information Management System for Hawaiian non-marine algal data. Users can interact with the repository through the web to view relevant habitat data (including geo-referenced collection locations and download images of collection sites, specimen

    Malignant mesothelioma (MM) is one of the most aggressive neoplasms usually associated with asbestos exposure and is highly refractory to current therapeutic modalities. MMs show frequent activation of a transcriptional coactivator Yes-associated protein (YAP), which is attributed to the neurofibromatosis type 2 (NF2)-Hippo pathway dysfunction, leading to deregulated cell proliferation and acquisition of a malignant phenotype. However, the whole mechanism of disordered YAP activation in MMs has not yet been well clarified. In the present study, we investigated various components of the NF2-Hippo pathway, and eventually found that MM cells frequently showed downregulation of LIM-domain protein AJUBA, a binding partner of large tumor suppressor type 2 (LATS2), which is one of the last-step kinases of the NF2-Hippo pathway. Although loss of AJUBA expression was independent of the alteration status of other Hippo pathway components, MM cell lines with AJUBA inactivation showed a more dephosphorylated (activated) level of YAP. Immunohistochemical analysis showed frequent downregulation of AJUBA in primary MMs, which was associated with YAP constitutive activation. We found that AJUBA transduction into MM cells significantly suppressed promoter activities of YAP-target genes, and the suppression of YAP activity by AJUBA was remarkably canceled by knockdown of LATS2. In connection with these results, transduction of AJUBA-expressing lentivirus significantly inhibited the proliferation and anchorage-independent growth of the MM cells that harbored ordinary LATS family expression. Taken together, our findings indicate that AJUBA negatively regulates YAP activity through the LATS family, and inactivation of AJUBA is a novel key mechanism in MM cell proliferation.

    A considerable effort has been devoted to retrieve systematically information for genes and proteins as well as relationships between them. Despite the importance of chemical compounds and drugs as a central bio-entity in pharmacological and biological research, only a limited number of freely available chemical text-mining/search engine technologies are currently accessible. Here we present LimTox (Literature Mining for Toxicology), a web-based online biomedical search tool with special focus on adverse hepatobiliary reactions. It integrates a range of text mining, named entity recognition and information extraction components. LimTox relies on machine-learning, rule-based, pattern-based and term lookup strategies. This system processes scientific abstracts, a set of full text articles and medical agency assessment reports. Although the main focus of LimTox is on adverse liver events, it enables also basic searches for other organ level toxicity associations (nephrotoxicity, cardiotoxicity, thyrotoxicity and phospholipidosis). This tool supports specialized search queries for: chemical compounds/drugs, genes (with additional emphasis on key enzymes in drug metabolism, namely P450 cytochromes-CYPs) and biochemical liver markers. The LimTox website is free and open to all users and there is no login requirement. LimTox can be accessed at: http://limtox.bioinfo.cnio.es. © The Author(s) 2017.

  7. Lim homeobox genes in the Ctenophore Mnemiopsis leidyi: the evolution of neural cell type specification

    2012-01-01

    Full Text Available Abstract Background Nervous systems are thought to be important to the evolutionary success and diversification of metazoans, yet little is known about the origin of simple nervous systems at the base of the animal tree. Recent data suggest that ctenophores, a group of macroscopic pelagic marine invertebrates, are the most ancient group of animals that possess a definitive nervous system consisting of a distributed nerve net and an apical statocyst. This study reports on details of the evolution of the neural cell type specifying transcription factor family of LIM homeobox containing genes (Lhx, which have highly conserved functions in neural specification in bilaterian animals. Results Using next generation sequencing, the first draft of the genome of the ctenophore Mnemiopsis leidyi has been generated. The Lhx genes in all animals are represented by seven subfamilies (Lhx1/5, Lhx3/4, Lmx, Islet, Lhx2/9, Lhx6/8, and LMO of which four were found to be represented in the ctenophore lineage (Lhx1/5, Lhx3/4, Lmx, and Islet. Interestingly, the ctenophore Lhx gene complement is more similar to the sponge complement (sponges do not possess neurons than to either the cnidarian-bilaterian or placozoan Lhx complements. Using whole mount in situ hybridization, the Lhx gene expression patterns were examined and found to be expressed around the blastopore and in cells that give rise to the apical organ and putative neural sensory cells. Conclusion This research gives us a first look at neural cell type specification in the ctenophore M. leidyi. Within M. leidyi, Lhx genes are expressed in overlapping domains within proposed neural cellular and sensory cell territories. These data suggest that Lhx genes likely played a conserved role in the patterning of sensory cells in the ancestor of sponges and ctenophores, and may provide a link to the expression of Lhx orthologs in sponge larval photoreceptive cells. Lhx genes were later co-opted into patterning more

    The reliability and accuracy of isotopic data can be improved by utilizing database software to (i) store information about samples, (ii) store the results of mass spectrometric isotope-ratio analyses of samples, (iii) calculate analytical results using standardized algorithms stored in a database, (iv) normalize stable isotopic data to international scales using isotopic reference materials, and (v) generate multi-sheet paper templates for convenient sample loading of automated mass-spectrometer sample preparation manifolds. Such a database program, the Laboratory Information Management System (LIMS) for Light Stable Isotopes, is presented herein. Major benefits of this system include (i) a dramatic improvement in quality assurance, (ii) an increase in laboratory efficiency, (iii) a reduction in workload due to the elimination or reduction of retyping of data by laboratory personnel, and (iv) a decrease in errors in data reported to sample submitters. Such a database provides a complete record of when and how often laboratory reference materials have been analyzed and provides a record of what correction factors have been used through time. It provides an audit trail for laboratories. LIMS for Light Stable Isotopes is available for both Microsoft Office 97 Professional and Microsoft Office 2000 Professional as versions 7 and 8, respectively. Both source code (mdb file) and precompiled executable files (mde) are available. Numerous improvements have been made for continuous flow isotopic analysis in this version (specifically 7.13 for Microsoft Access 97 and 8.13 for Microsoft Access 2000). It is much easier to import isotopic results from Finnigan ISODAT worksheets, even worksheets on which corrections for amount of sample (linearity corrections) have been added. The capability to determine blank corrections using isotope mass balance from analyses of elemental analyzer samples has been added. It is now possible to calculate and apply drift corrections to isotopic

  9. The IMF’s High Interest Rate Policy and Its Effects on the Stabilization of the Korean Won

    2000-03-01

    Full Text Available There has been a lively debate whether high interest rates were effective in stabilizing the exchange rate in the wake of the Asian currency crisis. Many economists insist that high interest rates not only failed to stabilize the Korean won, but also exacerbated the crisis itself. This paper tries to shed light on this problem by providing empirical evidence from the high interest rate period. (1997. 12. 3 ? 1998. 4. 8 If possible channels whereby interest rates may affect exchange rates are examined, the high interest rate policy scores well. It accommodated net capital inflow by satisfying the interest rate parity condition. Also it helped rebuild credibility of the policy stance. While the negative impact of high interest rates on the private sector cannot be denied, the role of credit crunch needs to be recognized together. Next, the dynamic interaction between interest rates and exchange rates is analyzed using a vector error correction model composed of interest rate differential, spot and forward exchange rates, and country risk premium. The estimation result shows that a 10% point rise in domestic interest rate appreciates the Korean won by 25%. In addition, the country risk premium considerably falls down. In sum, it may be concluded that the high interest rate policy was effective in achieving its goal of stabilizing exchange rates.

    Sea ice is a highly dynamical environment characterized by a dense mesh of fractures or leads, constantly opening and closing over short time scales. This characteristic geomorphology is linked to the existence of linear kinematic features, which consist of quasi-linear patterns emerging from the observed strain rate field of sea ice. Standard rheologies used in most state-of-the-art sea ice models, like the well-known elastic-viscous-plastic rheology, are thought to misrepresent those linear kinematic features and the observed statistical distribution of deformation rates. Dedicated rheologies built to catch the processes known to be at the origin of the formation of leads are developed but still need evaluations on the global scale. One of them, based on a Maxwell elasto-brittle formulation, is being integrated in the NEMO-LIM3 global ocean-sea ice model (www.nemo-ocean.eu; www.elic.ucl.ac.be/lim). In the present study, we compare the results of the sea ice model LIM3 obtained with two different rheologies: the elastic-viscous-plastic rheology commonly used in LIM3 and a Maxwell elasto-brittle rheology. This comparison is focused on the statistical characteristics of the simulated deformation rate and on the ability of the model to reproduce the existence of leads within the ice pack. The impact of the lead representation on fluxes between ice, atmosphere and ocean is also assessed.

  13. Investigations of impurity control in JET using fuelling, and interpretation of experiments using the LIM impurity code

    1994-01-01

    Inhibition of contamination of the plasma core in JET by edge impurities during high power heating of deuterium plasmas in limiter configuration using fuelling is demonstrated. By injecting deuterium gas during heating, in the presence of a much larger recycling deuterium flux, a reduction of more than a factor of 2 was effected in n z (0)/Φ z , the ratio of central impurity density to impurity influx at the plasma edge. The reduction in n z (0) was obtained without much effect on peak electron temperature and density. Reduction of plasma contamination by gas fuelling was observed also when hot spots formed on the limiter, a condition that without simultaneous gas fuelling culminated in runaway plasma contamination. Detailed analysis of the experiments is undertaken with the purpose of identifying the processes by which plasma contamination was inhibited, employing standard limiter plasma contamination modelling. Processes which might produce the observed impurity inhibiting effects of gas injection include: (a) reduction in impurity production at the limiter; (b) increase in impurity screening in the scrape-off layer; (c) increase in radial impurity transport at the plasma edge; (d) increase in average deuteron flow velocity to the limiter along the scrape-off layer. These are examined in detail using the Monte Carlo limiter impurity transport code LIM. Bearing in mind that uncertainties exist both in the choice of appropriate modelling assumptions to be used and in the measurement of required edge plasma parameters, changes in n z (0)/Φ z by a factor of 2 are at the limit of the present modelling capability. However, comparison between LIM code simulations and measurements of plasma impurity content indicate that the standard limiter plasma contamination model may not be adequate and that other processes need to be added in order to be able to describe the experiments in JET.

    We previously demonstrated that hematopoietic stem cell (HSC)-like cells are robustly expanded from mouse embryonic stem cells (ESCs) by enforced expression of Lhx2, a LIM-homeobox domain (LIM-HD) transcription factor. In this study, we analyzed the functions of Lhx2 in that process using an ESC line harboring an inducible Lhx2 gene cassette. When ESCs are cultured on OP9 stromal cells, hematopoietic progenitor cells (HPCs) are differentiated and these HPCs are prone to undergo rapid differentiation into mature hematopoietic cells. Lhx2 inhibited differentiation of HPCs into mature hematopoietic cells and this effect would lead to accumulation of HSC-like cells. LIM-HD factors interact with LIM domain binding (Ldb) protein and this interaction abrogates binding of LIM-only (Lmo) protein to Ldb. We found that one of Lmo protein, Lmo2, was unstable due to dissociation of Lmo2 from Ldb1 in the presence of Lhx2. This effect of Lhx2 on the amount of Lmo2 contributed into accumulation of HSC-like cells, since enforced expression of Lmo2 into HSC-like cells inhibited their self-renewal. Expression of Gata3 and Tal1/Scl was increased in HSC-like cells and enforced expression of Lmo2 reduced expression of Gata3 but not Tal1/Scl. Enforced expression of Gata3 into HPCs inhibited mature hematopoietic cell differentiation, whereas Gata3-knockdown abrogated the Lhx2-mediated expansion of HPCs. We propose that multiple transcription factors/cofactors are involved in the Lhx2-mediated expansion of HSC-like cells from ESCs. Lhx2 appears to fine-tune the balance between self-renewal and differentiation of HSC-like cells. © AlphaMed Press.

    Kwang Hye Won(Je Joong Won), the first western hospital in Korea, was founded in 1885. The first western Medical School in Korea was open in 1886 under the hospital management. Dr. O. R. Avison, who came to Korea in 1893, resumed the medical education there, which was interrupted for some time before his arrival in Korea. He inaugurated translating and publishing medical textbooks with the help of Kim Pil Soon who later became one of the first seven graduates in Severance Hospital Medical School. The first western medical textbook translated into Korean was Henry Gray's Anatomy. However, these twice-translated manuscripts were never to be published on account of being lost and burnt down. The existing early anatomy textbooks, the editions of 1906 and 1909, are not the translation of Gray's Anatomy, but that of Japanese anatomy textbook of Gonda. The remaining oldest medical textbook in Korean is Inorganic Materia Medica published in 1905. This book is unique among its kind that O. R. Avison is the only translator of the book and it contains the prefaces of O. R. Avison and Kim Pil Soon. The publication of medical textbook was animated by the participation of other medical students, such as Hong Suk Hoo and Hong Jong Eun. The list of medical textbooks published includes almost all the field of medicine. The medical textbooks in actual existence are as follows: Inorganic Materia Medica (1905), Inorganic Chemistry (1906), Anatomy I (1906), Physiology (1906), Diagnostics I (1906), Diagnostics II (1907), Obstetrics (1908), Organic Chemistry (1909), Anatomy (1909), and Surgery (1910).

  16. The terminal basal mitosis of chicken retinal Lim1 horizontal cells is not sensitive to cisplatin-induced cell cycle arrest.

    For proper development, cells need to coordinate proliferation and cell cycle-exit. This is mediated by a cascade of proteins making sure that each phase of the cell cycle is controlled before the initiation of the next. Retinal progenitor cells divide during the process of interkinetic nuclear migration, where they undergo S-phase on the basal side, followed by mitoses on the apical side of the neuroepithelium. The final cell cycle of chicken retinal horizontal cells (HCs) is an exception to this general cell cycle behavior. Lim1 expressing (+) horizontal progenitor cells (HPCs) have a heterogenic final cell cycle, with some cells undergoing a terminal mitosis on the basal side of the retina. The results in this study show that this terminal basal mitosis of Lim1+ HPCs is not dependent on Chk1/2 for its regulation compared to retinal cells undergoing interkinetic nuclear migration. Neither activating nor blocking Chk1 had an effect on the basal mitosis of Lim1+ HPCs. Furthermore, the Lim1+ HPCs were not sensitive to cisplatin-induced DNA damage and were able to continue into mitosis in the presence of γ-H2AX without activation of caspase-3. However, Nutlin3a-induced expression of p21 did reduce the mitoses, suggesting the presence of a functional p53/p21 response in HPCs. In contrast, the apical mitoses were blocked upon activation of either Chk1/2 or p21, indicating the importance of these proteins during the process of interkinetic nuclear migration. Inhibiting Cdk1 blocked M-phase transition both for apical and basal mitoses. This confirmed that the cyclin B1-Cdk1 complex was active and functional during the basal mitosis of Lim1+ HPCs. The regulation of the final cell cycle of Lim1+ HPCs is of particular interest since it has been shown that the HCs are able to sustain persistent DNA damage, remain in the cell cycle for an extended period of time and, consequently, survive for months.

    Members of the cysteine-rich protein (CRP) family are actin cytoskeleton-interacting LIM-domain proteins known to act in muscle cell differentiation. We have earlier found that CRP1, a founding member of this family, is transcriptionally induced by UV radiation in human diploid fibroblasts [M. Gentile, L. Latonen, M. Laiho, Cell cycle arrest and apoptosis provoked by UV radiation-induced DNA damage are transcriptionally highly divergent responses, Nucleic Acids Res. 31 (2003) 4779-4790]. Here we show that CRP1 is induced by growth-inhibitory signals, such as increased cellular density, and cytotoxic stress induced by UV radiation or staurosporine. We found that high levels of CRP1 correlate with differentiation-associated morphology towards the myofibroblast lineage and that expression of ectopic CRP1 suppresses cell proliferation. Following UV- and staurosporine-induced stresses, expression of CRP1 provides a survival advantage evidenced by decreased cellular death and increased cellular metabolic activity and attachment. Our studies identify that CRP1 is a novel stress response factor, and provide evidence for its growth-inhibitory and cytoprotective functions

    Full Text Available This paper explores the understanding of tarbawi (education hadith from one of the major influential clerics in the Islamic educational system, especially in pesantren. He is Burhan al Islam al Zarnuji with his landmark book Ta’lim al Muta’allim. The conclusion that can be drawn is that al Zarnuji has shades of sufistical view in understanding tarbawi hadith. This can be seen in his understanding of hadith on obligation to seek knowledge (thalab al ilmi faridhatun ‘ala kulli muslimin wa muslimatin, which is interpreted as ilm al hal, the science concerning the condition of the human religious or simplistically said as the religious sciences; and the hadith of intention of studying (innama al a’malu bi al niyyat with the intention for the sake of the hereafter and religion, not mundane. Such an understanding is not something taken for granted, but it can be reinterpreted and perfected in accordance with the spirit of the times of context.

    Full Text Available Abstract Background LIM kinase 1 (LIMK1 is an actin and microtubule cytoskeleton modulatory protein that is overexpressed in a number of cancerous tissues and cells and also promotes invasion and metastasis of prostate and breast cancer cells. Membrane type matrix metalloproteinase 1 (MT1-MMP is a critical modulator of extracellular matrix (ECM turnover through pericellular proteolysis and thus plays crucial roles in neoplastic cell invasion and metastasis. MT1-MMP and its substrates pro-MMP-2 and pro-MMP-9 are often overexpressed in a variety of cancers including prostate cancer and the expression levels correlate with the grade of malignancy in prostate cancer cells. The purpose of this study is to determine any functional relation between LIMK1 and MT1-MMP and its implication in cell invasion. Results Our results showed that treatment with the hydroxamate inhibitor of MT1-MMP, MMP-2 and MMP-9 ilomastat inhibited LIMK1-induced invasion of benign prostate epithelial cells. Over expression of LIMK1 resulted in increased collagenolytic activity of MMP-2, and secretion of pro-MMP2 and pro-MMP-9. Cells over expressing LIMK1 also exhibited increased expression of MT1-MMP, transcriptional activation and its localization to the plasma membrane. LIMK1 physically associates with MT1-MMP and is colocalized with it to the Golgi vesicles. We also noted increased expression of both MT1-MMP and LIMK1 in prostate tumor tissues. Conclusion Our results provide new information on regulation of MT1-MMP function by LIMK1 and showed for the first time, involvement of MMPs in LIMK1 induced cell invasion.

    Sea ice thickness evolution within the Canadian Arctic Archipelago (CAA) is of great interest to science, as well as local communities and their economy. In this study, based on the NEMO numerical framework including the LIM2 sea ice module, simulations at both 1/4 and 1/12° horizontal resolution were conducted from 2002 to 2016. The model captures well the general spatial distribution of ice thickness in the CAA region, with very thick sea ice (˜ 4 m and thicker) in the northern CAA, thick sea ice (2.5 to 3 m) in the west-central Parry Channel and M'Clintock Channel, and thin ( Program data at first-year landfast ice sites except at the northern sites with high concentration of old ice. At 1/4 to 1/12° scale, model resolution does not play a significant role in the sea ice simulation except to improve local dynamics because of better coastline representation. Sea ice growth is decomposed into thermodynamic and dynamic (including all non-thermodynamic processes in the model) contributions to study the ice thickness evolution. Relatively smaller thermodynamic contribution to ice growth between December and the following April is found in the thick and very thick ice regions, with larger contributions in the thin ice-covered region. No significant trend in winter maximum ice volume is found in the northern CAA and Baffin Bay while a decline (r2 ≈ 0.6, p < 0.01) is simulated in Parry Channel region. The two main contributors (thermodynamic growth and lateral transport) have high interannual variabilities which largely balance each other, so that maximum ice volume can vary interannually by ±12 % in the northern CAA, ±15 % in Parry Channel, and ±9 % in Baffin Bay. Further quantitative evaluation is required.

  4. The US won the global currency war against Europe and Japan: Their retaliation likely helped elect Trump

    Full Text Available The United States financial community, lax regulations and the Fed started a global currency war in 2002. The inadvertent cheapening of the US dollar was a by-product of what became the US subprime lending crisis and the financial collapse in 2008. From 2002-2008, the Fed created so much liquidity that the dollar fell 33% relative to the yen and 40% relative to the euro. In response to the 2008 crash, the Fed had to ramp up US money creation again, generating $4 trillion in money creation by 2014. World interest rates fell and raw materials and commodity producers in emerging markets borrowed nearly $5 trillion. Overproduction and the slowdown of China caused a Third World oil and commodity market collapse around 2015. Beginning in 2014, other advanced countries retaliated and declared a global currency war of their own against United States. They created their money with a vengeance. Just as the US had done, this made the currencies of Europe, Japan and Britain 20 to 25% cheaper and their goods became more competitive relative to US goods. As a result, the US became the importer of last resort for cheap foreign goods from 2014 until the election in November of 2016. Only time will tell whether the US currency war that we won from 2002-2014 and the retaliation war we lost from 2014-2016 helped Trump get elected. The parallel is inescapable that the US also started the world tariff and trade war in 1930 with the passage of the Smoot Hawley tariff, which extended the length of the Great Depression. The US currency war pushed Japan even further into recession and weakened Europe. US quantitative easing became a beggar-thy-neighbor policy against our trading partners.

  5. The Ras suppressor Rsu-1 binds to the LIM 5 domain of the adaptor protein PINCH1 and participates in adhesion-related functions

    2005-01-01

    Rsu-1 is a highly conserved leucine rich repeat (LRR) protein that is expressed ubiquitously in mammalian cells. Rsu-1 was identified based on its ability to inhibit transformation by Ras, and previous studies demonstrated that ectopic expression of Rsu-1 inhibited anchorage-independent growth of Ras-transformed cells and human tumor cell lines. Using GAL4-based yeast two-hybrid screening, the LIM domain protein, PINCH1, was identified as the binding partner of Rsu-1. PINCH1 is an adaptor protein that localizes to focal adhesions and it has been implicated in the regulation of adhesion functions. Subdomain mapping in yeast revealed that Rsu-1 binds to the LIM 5 domain of PINCH1, a region not previously identified as a specific binding domain for any other protein. Additional testing demonstrated that PINCH2, which is highly homologous to PINCH1, except in the LIM 5 domain, does not interact with Rsu-1. Glutathione transferase fusion protein binding studies determined that the LRR region of Rsu-1 interacts with PINCH1. Transient expression studies using epitope-tagged Rsu-1 and PINCH1 revealed that Rsu-1 co-immunoprecipitated with PINCH1 and colocalized with vinculin at sites of focal adhesions in mammalian cells. In addition, endogenous P33 Rsu-1 from 293T cells co-immunoprecipitated with transiently expressed myc-tagged PINCH1. Furthermore, RNAi-induced reduction in Rsu-1 RNA and protein inhibited cell attachment, and while previous studies demonstrated that ectopic expression of Rsu-1 inhibited Jun kinase activation, the depletion of Rsu-1 resulted in activation of Jun and p38 stress kinases. These studies demonstrate that Rsu-1 interacts with PINCH1 in mammalian cells and functions, in part, by altering cell adhesion

  6. The structure of an LIM-only protein 4 (LMO4 and Deformed epidermal autoregulatory factor-1 (DEAF1 complex reveals a common mode of binding to LMO4.

    Directory of Open Access Journals (Sweden)

    Soumya Joseph

    Full Text Available LIM-domain only protein 4 (LMO4 is a widely expressed protein with important roles in embryonic development and breast cancer. It has been reported to bind many partners, including the transcription factor Deformed epidermal autoregulatory factor-1 (DEAF1, with which LMO4 shares many biological parallels. We used yeast two-hybrid assays to show that DEAF1 binds both LIM domains of LMO4 and that DEAF1 binds the same face on LMO4 as two other LMO4-binding partners, namely LIM domain binding protein 1 (LDB1 and C-terminal binding protein interacting protein (CtIP/RBBP8. Mutagenic screening analysed by the same method, indicates that the key residues in the interaction lie in LMO4LIM2 and the N-terminal half of the LMO4-binding domain in DEAF1. We generated a stable LMO4LIM2-DEAF1 complex and determined the solution structure of that complex. Although the LMO4-binding domain from DEAF1 is intrinsically disordered, it becomes structured on binding. The structure confirms that LDB1, CtIP and DEAF1 all bind to the same face on LMO4. LMO4 appears to form a hub in protein-protein interaction networks, linking numerous pathways within cells. Competitive binding for LMO4 therefore most likely provides a level of regulation between those different pathways.

  9. Heterogenic final cell cycle by chicken retinal Lim1 horizontal progenitor cells leads to heteroploid cells with a remaining replicated genome.

    Directory of Open Access Journals (Sweden)

    Shahrzad Shirazi Fard

    Full Text Available Retinal progenitor cells undergo apical mitoses during the process of interkinetic nuclear migration and newly generated post-mitotic neurons migrate to their prospective retinal layer. Whereas this is valid for most types of retinal neurons, chicken horizontal cells are generated by delayed non-apical mitoses from dedicated progenitors. The regulation of such final cell cycle is not well understood and we have studied how Lim1 expressing horizontal progenitor cells (HPCs exit the cell cycle. We have used markers for S- and G2/M-phase in combination with markers for cell cycle regulators Rb1, cyclin B1, cdc25C and p27Kip1 to characterise the final cell cycle of HPCs. The results show that Lim1+ HPCs are heterogenic with regards to when and during what phase they leave the final cell cycle. Not all horizontal cells were generated by a non-apical (basal mitosis; instead, the HPCs exhibited three different behaviours during the final cell cycle. Thirty-five percent of the Lim1+ horizontal cells was estimated to be generated by non-apical mitoses. The other horizontal cells were either generated by an interkinetic nuclear migration with an apical mitosis or by a cell cycle with an S-phase that was not followed by any mitosis. Such cells remain with replicated DNA and may be regarded as somatic heteroploids. The observed heterogeneity of the final cell cycle was also seen in the expression of Rb1, cyclin B1, cdc25C and p27Kip1. Phosphorylated Rb1-Ser608 was restricted to the Lim1+ cells that entered S-phase while cyclin B1 and cdc25C were exclusively expressed in HPCs having a basal mitosis. Only HPCs that leave the cell cycle after an apical mitosis expressed p27Kip1. We speculate that the cell cycle heterogeneity with formation of heteroploid cells may present a cellular context that contributes to the suggested propensity of these cells to generate cancer when the retinoblastoma gene is mutated.

  17. Effects of different agricultural systems on soil quality in Northern Limón province, Costa Rica

    Directory of Open Access Journals (Sweden)

    Emma Cornwell

    2014-09-01

    Full Text Available Conversion of native rainforest ecosystems in Limón Province of Costa Rica to banana and pineapple monoculture has led to reductions in biodiversity and soil quality. Agroforestry management of cacao (Theobroma cacao is an alternative system that may maintain the agricultural livelihood of the region while more closely mimicking native ecosystems. This study compared physical, biological and chemical soil quality indicators of a cacao plantation under organic agroforestry management with banana, pineapple, and pasture systems; a native forest nearby served as a control. For bulk density and earthworm analysis, 18 samples were collected between March and April 2012 from each ecosystem paired with 18 samples from the cacao. Cacao had a lower bulk density than banana and pineapple monocultures, but greater than the forest (p<0.05. Cacao also hosted a greater number and mass of earthworms than banana and pineapple (p<0.05, but similar to forest and pasture. For soil chemical characteristics, three composite samples were collected in March 2012 from each agroecosystem paired with three samples from the cacao plantation. Forest and pineapple ecosystems had the lowest pH, cation exchange capacity, and exchangeable nutrient cations, while cacao had the greatest (p<0.05. Total nutrient levels of P and N were slightly greater in banana, pineapple and pasture than in cacao; probably related to addition of chemical fertilizer and manure from cattle grazing. Forest and cacao also had greater %C, than other ecosystems, which is directly related to soil organic matter content (p<0.0001. Overall, cacao had more favorable physical, biological and chemical soil characteristics than banana and pineapple monocultures, while trends were less conclusive compared to the pastureland. While organic cacao was inferior to native forest in some soil characteristics such as bulk density and organic carbon, its soil quality did best mimic that of the native forest. This

  18. Mouse transgenesis identifies conserved functional enhancers and cis-regulatory motif in the vertebrate LIM homeobox gene Lhx2 locus.

    Directory of Open Access Journals (Sweden)

    Alison P Lee

    Full Text Available The vertebrate Lhx2 is a member of the LIM homeobox family of transcription factors. It is essential for the normal development of the forebrain, eye, olfactory system and liver as well for the differentiation of lymphoid cells. However, despite the highly restricted spatio-temporal expression pattern of Lhx2, nothing is known about its transcriptional regulation. In mammals and chicken, Crb2, Dennd1a and Lhx2 constitute a conserved linkage block, while the intervening Dennd1a is lost in the fugu Lhx2 locus. To identify functional enhancers of Lhx2, we predicted conserved noncoding elements (CNEs in the human, mouse and fugu Crb2-Lhx2 loci and assayed their function in transgenic mouse at E11.5. Four of the eight CNE constructs tested functioned as tissue-specific enhancers in specific regions of the central nervous system and the dorsal root ganglia (DRG, recapitulating partial and overlapping expression patterns of Lhx2 and Crb2 genes. There was considerable overlap in the expression domains of the CNEs, which suggests that the CNEs are either redundant enhancers or regulating different genes in the locus. Using a large set of CNEs (810 CNEs associated with transcription factor-encoding genes that express predominantly in the central nervous system, we predicted four over-represented 8-mer motifs that are likely to be associated with expression in the central nervous system. Mutation of one of them in a CNE that drove reporter expression in the neural tube and DRG abolished expression in both domains indicating that this motif is essential for expression in these domains. The failure of the four functional enhancers to recapitulate the complete expression pattern of Lhx2 at E11.5 indicates that there must be other Lhx2 enhancers that are either located outside the region investigated or divergent in mammals and fishes. Other approaches such as sequence comparison between multiple mammals are required to identify and characterize such enhancers.

Aunque con ligeras diferencias la dinámica de daños del MHC fue muy similar en los tres sitios. El insecto estuvo presente durante todo el año, pero la mayor intensidad de daños se presenta de octubre a diciembre y de mayo a julio cuando se alcanza hasta un 90 % de hojas afectadas. Se obtuvieron altos valores de correlación entre las variables: porcentaje de hojas minadas (PHM, promedio de minas por hoja (NMH, porcentaje de área foliar minada (PAFM y porcentaje de enrollamiento de la lamina foliar (PEF. Las temperaturas mínimas por debajo de 15 °C registradas durante los meses de invierno (enero, febrero y marzo estuvieron asociadas con los niveles de daño más bajos. Durante la época de lluvias (julio a septiembre, la reducción en los valores de daños coincidió con la alta incidencia antracnosis (Colletotrichum acutatum así como con un incremento en la población de depredadores del MHC. No se detectó un impacto significativo del daño al follaje causado por el MHC sobre el rendimiento de los árboles de limón mexicano

Con el fin de evaluar esta relación, se analizó la presencia de parásitos en los intestinos de esta especie. El estudio se realizó en la Estación Biológica La Suerte (EBLS, Limón, Costa Rica. El grupo de monos capuchinos cariblancos (Cebus capucinus fue observado entre marzo y diciembre de 2006. Se recolectaron 75 muestras de heces a las que se les identificó las plantas ingeridas, y se procesaron en el laboratorio para evaluar la prevalencia de parásitos. Moraceae fue la familia de plantas más reportada. Strongyloides spp. y acantocéfalos fueron los más comunes. La distribución positiva de las mismas fue similar independientemente del sexo y la edad. Microsporidios se reportaron mayoritariamente en heces asociadas con la familia Piperaceae. Fue encontrada una baja existencia de éstos parásitos en muestras asociadas con Myrtaceae en cuyo género Psidium, se han reportado compuestos activos antiparasitarios. La aparición de parásitos fue relativamente mayor en la EBLS, comparado con muestras de otras regiones más secas de Costa Rica. Por lo tanto, esa expresión parasitaria puede deberse al hecho de ser la EBLS una selva lluviosa, además de estar rodeada por zonas con actividades antrópicas. Se sugiere incrementar las investigaciones de parasitología de campo en primates neotropicales con el fin de entender plenamente las relaciones parásitos-hospederos, para en un largo plazo poder comprender los ecosistemas donde conviven, y en consecuencia, preservar la diversidad biológica.Intestinal parasites in white-faced capuchin monkeys Cebus capucinus Primates: Cebidae inhabiting a protected area in the Limón province of Northeastern Costa Rica.

    Full Text Available Abstract Background The cysteine and glycine rich protein 2 (CRP2 encoded by the Csrp2 gene is a LIM domain protein expressed in the vascular system, particularly in smooth muscle cells. It exhibits a bimodal subcellular distribution, accumulating at actin-based filaments in the cytosol and in the nucleus. In order to analyze the function of CRP2 in vivo, we disrupted the Csrp2 gene in mice and analysed the resulting phenotype. Results A ~17.3 kbp fragment of the murine Csrp2 gene containing exon 3 through 6 was isolated. Using this construct we confirmed the recently determined chromosomal localization (Chromosome 10, best fit location between markers D10Mit203 proximal and D10Mit150 central. A gene disruption cassette was cloned into exon 4 and a mouse strain lacking functional Csrp2 was generated. Mice lacking CRP2 are viable and fertile and have no obvious deficits in reproduction and survival. However, detailed histological and electron microscopic studies reveal that CRP2-deficient mice have subtle alterations in their cardiac ultrastructure. In these mice, the cardiomyocytes display a slight increase in their thickness, indicating moderate hypertrophy at the cellular level. Although the expression of several intercalated disc-associated proteins such as β-catenin, N-RAP and connexin-43 were not affected in these mice, the distribution of respective proteins was changed within heart tissue. Conclusion We conclude that the lack of CRP2 is associated with alterations in cardiomyocyte thickness and hypertrophy.

    Transcription factors that drive neuron type-specific terminal differentiation programs in the developing nervous system are often expressed in several distinct neuronal cell types, but to what extent they have similar or distinct activities in individual neuronal cell types is generally not well explored. We investigate this problem using, as a starting point, the C. elegans LIM homeodomain transcription factor ttx-3, which acts as a terminal selector to drive the terminal differentiation program of the cholinergic AIY interneuron class. Using a panel of different terminal differentiation markers, including neurotransmitter synthesizing enzymes, neurotransmitter receptors and neuropeptides, we show that ttx-3 also controls the terminal differentiation program of two additional, distinct neuron types, namely the cholinergic AIA interneurons and the serotonergic NSM neurons. We show that the type of differentiation program that is controlled by ttx-3 in different neuron types is specified by a distinct set of collaborating transcription factors. One of the collaborating transcription factors is the POU homeobox gene unc-86, which collaborates with ttx-3 to determine the identity of the serotonergic NSM neurons. unc-86 in turn operates independently of ttx-3 in the anterior ganglion where it collaborates with the ARID-type transcription factor cfi-1 to determine the cholinergic identity of the IL2 sensory and URA motor neurons. In conclusion, transcription factors operate as terminal selectors in distinct combinations in different neuron types, defining neuron type-specific identity features.

    Highlights: Black-Right-Pointing-Pointer Lmo2 expression is elevated in Lck-transformed cells. Black-Right-Pointing-Pointer Both endogenous and exogenous Lck localize in the nucleus. Black-Right-Pointing-Pointer Nuclear Lck is active in Lck-transformed cells. Black-Right-Pointing-Pointer Lck binds to the promoter region of Lmo2 gene in vivo. Black-Right-Pointing-Pointer In contrast to JAK2, Lck does not increase histone H3 phosphorylation on Tyr 41. -- Abstract: LIM domain only protein 2 (Lmo2) is a transcription factor that plays a critical role in the development of T-acute lymphoblastic leukemia (T-ALL). A previous report established a link between Lmo2 expression and the nuclear presence of oncogenic Janus kinase 2 (JAK2), a non-receptor protein tyrosine kinase. The oncogenic JAK2 kinase phosphorylates histone H3 on Tyr 41 that leads to the relief of Lmo2 promoter repression and subsequent gene expression. Similar to JAK2, constitutive activation of lymphocyte-specific protein tyrosine kinase (Lck) has been implicated in lymphoid malignancies. However, it is not known whether oncogenic Lck regulates Lmo2 expression through a similar mechanism. We show here that Lmo2 expression is significantly elevated in T cell leukemia LSTRA overexpressing active Lck kinase and in HEK 293 cells expressing oncogenic Y505FLck kinase. Nuclear localization of active Lck kinase was confirmed in both Lck-transformed cells by subcellular fractionation and immunofluorescence microscopy. More importantly, in contrast to oncogenic JAK2, oncogenic Lck kinase does not result in significant increase in histone H3 phosphorylation on Tyr 41. Instead, chromatin immunoprecipitation experiment shows that oncogenic Y505FLck kinase binds to the Lmo2 promoter in vivo. This result raises the possibility that oncogenic Lck may activate Lmo2 promoter through direct interaction.

    LIM and SH3 domain protein 1 (LASP1) has been implicated in several human malignancies and has been shown to predict PSA recurrence in prostate cancer. However, the anti-tumor effect of LASP1 knockdown and the association between LASP1 and the androgen receptor (AR) remains unclear. The aim of this study is to clarify the significance of LASP1 as a target for prostate cancer, and to test the effect of silencing LASP1 in vivo using antisense oligonucleotides (ASO). A tissue microarray (TMA) was performed to characterize the differences in LASP1 expression in prostate cancer treated after hormone deprivation therapy. Flow cytometry was used to analyze cell cycle. We designed LASP1 ASO for knockdown of LASP1 in vivo studies. The expression of LASP1 in TMA was increased after androgen ablation and persisted in castration resistant prostate cancer (CRPC). Also in TMA, compared with LNCaP cell, LASP1 expression is elevated in CRPC cell lines (C4-2 and VehA cells). Interestingly, suppression of AR elevated LASP1 expression conversely, AR activation decreased LASP1 expression. Silencing of LASP1 reduced cell growth through G1 arrest which was accompanied by a decrease of cyclin D1. Forced overexpression of LASP1 promoted cell cycle and induced cell growth which was accompanied by an increase of cyclin D1. Systemic administration of LASP1 ASO with athymic mice significantly inhibited tumor growth in CRPC xenografts. These results indicate that LASP1 is negatively regulated by AR at the transcriptional level and promotes tumor growth through induction of cell cycle, ultimately suggesting that LASP1 may be a potential target in prostate cancer treatment.

    Endothelial cell (EC) inflammation is a central event in the pathogenesis of many pulmonary diseases such as acute lung injury and its more severe form acute respiratory distress syndrome. Alterations in actin cytoskeleton are shown to be crucial for NF-κB regulation and EC inflammation. Previously, we have described a role of actin binding protein cofilin in mediating cytoskeletal alterations essential for NF-κB activation and EC inflammation. The present study describes a dynamic mechanism in which LIM kinase 1 (LIMK1), a cofilin kinase, and slingshot-1Long (SSH-1L), a cofilin phosphatase, are engaged by procoagulant and proinflammatory mediator thrombin to regulate these responses. Our data show that knockdown of LIMK1 destabilizes whereas knockdown of SSH-1L stabilizes the actin filaments through modulation of cofilin phosphorylation; however, in either case thrombin-induced NF-κB activity and expression of its target genes (ICAM-1 and VCAM-1) is inhibited. Further mechanistic analyses reveal that knockdown of LIMK1 or SSH-1L each attenuates nuclear translocation and thereby DNA binding of RelA/p65. In addition, LIMK1 or SSH-1L depletion inhibited RelA/p65 phosphorylation at Ser(536), a critical event conferring transcriptional competency to the bound NF-κB. However, unlike SSH-1L, LIMK1 knockdown also impairs the release of RelA/p65 by blocking IKKβ-dependent phosphorylation/degradation of IκBα. Interestingly, LIMK1 or SSH-1L depletion failed to inhibit TNF-α-induced RelA/p65 nuclear translocation and proinflammatory gene expression. Thus this study provides evidence for a novel role of LIMK1 and SSH-1L in selectively regulating EC inflammation associated with intravascular coagulation.

    Myofibrillar myopathies (MFMs) are genetically heterogeneous dystrophies characterized by the disintegration of Z-disks and myofibrils and are associated with mutations in genes encoding Z-disk or Z-disk-related proteins. The c.626 C > T (p.P209L) mutation in the BAG3 gene has been described as causative of a subtype of MFM. We report a sporadic case of a 26-year-old Italian woman, affected by MFM with axonal neuropathy, cardiomyopathy, rigid spine, who carries the c.626 C > T mutation in the BAG3 gene. The patient and her non-consanguineous healthy parents and brother were studied with whole exome sequencing (WES) to further investigate the genetic basis of this complex phenotype. In the patient, we found that the BAG3 mutation is associated with variants in the NRAP and FHL1 genes that encode muscle-specific, LIM domain containing proteins. Quantitative real time PCR, immunohistochemistry and Western blot analysis of the patient's muscular biopsy showed the absence of NRAP expression and FHL1 accumulation in aggregates in the affected skeletal muscle tissue. Molecular dynamic analysis of the mutated FHL1 domain showed a modification in its surface charge, which could affect its capability to bind its target proteins. To our knowledge this is the first study reporting, in a BAG3 MFM, the simultaneous presence of genetic variants in the BAG3 and FHL1 genes (previously described as independently associated with MFMs) and linking the NRAP gene to MFM for the first time.

    As the Human Genome and Drosophila Genome Projects were completed, it became clear that functions of human disease-associated genes may be elucidated by studying the phenotypic expression of mutations affecting their structural or functional homologs in Drosophila. Genomic diseases were identified as a new class of human disorders. Their cause is recombination, which takes place at gene-flanking duplicons to generate chromosome aberrations such as deletions, duplications, inversions, and translocations. The resulting imbalance of the dosage of developmentally important genes arises at a frequency of 10(-3) (higher than the mutation rate of individual genes) and leads to syndromes with multiple manifestations, including cognitive defects. Genomic DNA fragments were cloned from the Drosophila melanogaster agnostic locus, whose mutations impair learning ability and memory. As a result, the locus was exactly localized in X-chromosome region 11A containing the LIM kinase 1 (LIMK1) gene (CG1848), which is conserved among many species. Hemizygosity for the LIMK1 gene, which is caused by recombination at neighboring extended repeats, underlies cognitive disorders in human Williams syndrome. LIMK1 is a component of the integrin signaling cascade, which regulates the functions of the actin cytoskeleton, synaptogenesis, and morphogenesis in the developing brain. Immunofluorescence analysis revealed LIMK1 in all subdomains of the central complex and the visual system of Drosophila melanogaster. Like in the human genome, the D. melanogaster region is flanked by numerous repeats, which were detected by molecular genetic methods and analysis of ectopic chromosome pairing. The repeats determined a higher rate of spontaneous and induced recombination. including unequal crossing over, in the agnostic gene region. Hence, the agnostic locus was considered as the first D. melanogaster model suitable for studying the genetic defect associated with Williams syndrome in human.

    Dramatic declines and extinctions of amphibian populations throughout the world have been associated with chytridiomycosis, an infectious disease caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd). Previous studies indicated that Bd prevalence correlates with cooler temperatures in the field, and laboratory experiments have demonstrated that Bd ceases growth at temperatures above 28°C. Here we investigate how small-scale variations in water temperature correlate with Bd prevalence in the wild. We sampled 221 amphibians, including 201 lowland leopard frogs (Rana [Lithobates] yavapaiensis), from 12 sites in Arizona, USA, and tested them for Bd. Amphibians were encountered in microhabitats that exhibited a wide range of water temperatures (10-50°C), including several geothermal water sources. There was a strong inverse correlation between the water temperature in which lowland leopard frogs were captured and Bd prevalence, even after taking into account the influence of year, season, and host size. In locations where Bd was known to be present, the prevalence of Bd infections dropped from 75-100% in water 30°C. A strong inverse correlation between Bd infection status and water temperature was also observed within sites. Our findings suggest that microhabitats where water temperatures exceed 30°C provide lowland leopard frogs with significant protection from Bd, which could have important implications for disease dynamics, as well as management applications.There must be quite a few things a hot bath won't cure, but I don't know many of them--Sylvia Plath, "The Bell Jar" (1963).

    Full Text Available En el presente estudio, se realizaron visitas mensuales a la comunidad de Mata de Limón (diciembre 2011 a noviembre 2012 localizada en el Pacífico central de Costa Rica para evaluar una serie de aspectos pesqueros relativos a la extracción del camarón excavador Callichirus seilacheri. Esta especie llamada comúnmente coloncho por los recolectores locales es intensamente capturada y comercializada como carnada para la pesca deportiva en la costa del Pacífico de América Central. Los resultados indican que el esfuerzo pesquero varió entre 4 y 14 recolectores día-1 con un alto porcentaje de ellos procedentes de la misma comunidad (70-100%. Las capturas diarias variaron entre 76 y 1120 camarones dependiendo principalmente del esfuerzo pesquero realizado por recolectores locales (R² = 0,88. La densidad de colonchos fue de 1,2 ± 0,88 ind m-2 y su abundancia total en el Estero de Mata de Limón fue estimada en 49.607 ± 3.638 individuos. Las hembras ovígeras estuvieron presentes de mayo a noviembre, con un máximo en septiembre. Los resultados de este estudio indican que la población de colonchos puede estar en grave riesgo de sobre-explotación si las capturas diarias superan los 800 individuos. Por ello, se recomienda la implementación de una veda total durante el pico de reproducción de C. seilacheri de manera de que este recurso local sea protegido y conservado para su uso sostenible. Se sugiere además la implementación de un plan de manejo entre la comunidad de Mata de Limón y el Instituto Costarricense de Pesca y Acuicultura (INCOPESCA de manera de optimizar y legalizar la extracción de este recurso.

    Nuclear receptor transcriptional activity is enhanced by interaction with coactivators. The highly related nuclear receptor 5A (NR5A) subfamily members liver receptor homolog 1 and steroidogenic factor 1 bind to and activate several of the same genes, many of which are important for reproductive function. To better understand transcriptional activation by these nuclear receptors, we sought to identify interacting proteins that might function as coactivators. The LIM domain protein four and a half LIM domain 2 (FHL2) was identified as interacting with the NR5A receptors in a yeast two-hybrid screen of a human ovary cDNA library. FHL2, and the closely related FHL1, are both expressed in the rodent ovary and in granulosa cells. Small interfering RNA-mediated knockdown of FHL1 and FHL2 in primary mouse granulosa cells reduced expression of the NR5A target genes encoding inhibin-α and P450scc. In vitro assays confirmed the interaction between the FHL and NR5A proteins and revealed that a single LIM domain of FHL2 is sufficient for this interaction, whereas determinants in both the ligand binding domain and DNA binding domain of NR5A proteins are important. FHL2 enhances the ability of both liver receptor homolog 1 and steroidogenic factor 1 to activate the inhibin-α subunit gene promoter in granulosa cells and thus functions as a transcriptional coactivator. FHL2 also interacts with cAMP response element-binding protein and substantially augments activation of inhibin gene expression by the combination of NR5A receptors and forskolin, suggesting that FHL2 may facilitate integration of these two signals. Collectively these results identify FHL2 as a novel coactivator of NR5A nuclear receptors in ovarian granulosa cells and suggest its involvement in regulating target genes important for mammalian reproduction.

    2016-08-01

    Full Text Available Abstract The role of sea ice in the carbon cycle is minimally represented in current Earth System Models (ESMs. Among potentially important flaws, mentioned by several authors and generally overlooked during ESM design, is the link between sea-ice growth and melt and oceanic dissolved inorganic carbon (DIC and total alkalinity (TA. Here we investigate whether this link is indeed an important feature of the marine carbon cycle misrepresented in ESMs. We use an ocean general circulation model (NEMO-LIM-PISCES with sea-ice and marine carbon cycle components, forced by atmospheric reanalyses, adding a first-order representation of DIC and TA storage and release in/from sea ice. Our results suggest that DIC rejection during sea-ice growth releases several hundred Tg C yr−1 to the surface ocean, of which < 2% is exported to depth, leading to a notable but weak redistribution of DIC towards deep polar basins. Active carbon processes (mainly CaCO3 precipitation but also ice-atmosphere CO2 fluxes and net community production increasing the TA/DIC ratio in sea-ice modified ocean-atmosphere CO2 fluxes by a few Tg C yr−1 in the sea-ice zone, with specific hemispheric effects: DIC content of the Arctic basin decreased but DIC content of the Southern Ocean increased. For the global ocean, DIC content increased by 4 Tg C yr−1 or 2 Pg C after 500 years of model run. The simulated numbers are generally small compared to the present-day global ocean annual CO2 sink (2.6 ± 0.5 Pg C yr−1. However, sea-ice carbon processes seem important at regional scales as they act significantly on DIC redistribution within and outside polar basins. The efficiency of carbon export to depth depends on the representation of surface-subsurface exchanges and their relationship with sea ice, and could differ substantially if a higher resolution or different ocean model were used.

    Full Text Available El presente estudio se llevó a cabo en dos huertas de limón 'Persa' cada una en diferente tipo de suelo, con la finalidad de conocer la distribución de materia seca y nutrimentos en los órganos de cítricos y determinar su estado nutrimental. La huerta 1 de 12 años de edad estaba creciendo en suelo arcillo-migajón arenoso y la huerta 2, de 9 años de edad, en suelo arcilloso. El método de estudio consistió en extraer completamente cuatro árboles por huerta y fraccionarlos en sus diferentes órganos: hoja, flor, fruto, ramas, tronco y raíces. Las variables determinadas fueron: peso fresco y peso seco de cada órgano. Se determinó la concentración de nutrimentos por análisis químicos: N, P, K, Ca, Mg, B, Cu, Fe, Mn y Zn. Los datos de ambas huertas fueron sometidos a análisis de varianza y prueba de comparación de medias por separado. Las raíces fibrosas (< 1 mm de diámetro para ambas huertas presentaron concentraciones altas de micronutrimentos destacando Fe y Mn. Para ambas huertas los nutrimentos extraídos en mayor cantidad por el fruto fueron K y Ca; y en menor cantidad Zn y Cu. Con relación a la distribución de biomasa, el tronco y ramas aportaron el 60.32 %; el conjunto de raíces el 26.93 % y las hojas el 9.41 % de la materia seca total del árbol, mientras que el N en hojas representó el 17.5 % del total de la planta, en la huerta1. Esto representó 1.85 veces más de nitrógeno, con relación al peso seco de las hojas. Datos similares se tuvieron en la huerta 2. Para ambas huertas el Cu y el N fueron los nutrimentos más requeridos.

    Full Text Available Los desechos agroindustriales son uno de los principales problemas ambientales a nivel mundial. Debido a las altas exigencias de calidad, la comercialización de limones de exportación genera grandes cantidades de desechos. Los descartes de limón contienen fibra, pectina, potasio, calcio y vitamina C. Por lo tanto, es importante desarrollar alternativas de procesamiento de estos sub-productos para agregarles valor y aumentar su vida útil. El objetivo de la presente investigación fue la aplicación del secado asistido por infrarrojos, como tecnología emergente, para estudiar el efecto de la temperatura de proceso sobre las cinéticas de secado de descartes de limón a 30, 40 y 50°C. Se utilizaron seis modelos matemáticos de capa fina encontrados en literatura para representar la cinética experimental. Basándose en análisis estadístico, el modelo Logarítmico presentó el mejor ajuste. Los valores de la difusividad efectiva del agua se estimaron en el rango de 9.45× 10-10 – 3.71× 10-9 m/s2. El valor de la energía de activación fue 55.90 kJ/mol.

    Full Text Available A morte súbita dos citros é uma doença que afeta cultivares de laranjas e tangerinas enxertadas nos limões-Cravo e Volkameriano. Ela foi observada em plantas com dois a seis anos de idade que, após mostrarem sintomas gerais de declínio, entraram em colapso e morreram. A retirada da casca dos porta-enxertos suscetíveis revela o amarelecimento na região cambial, sendo esse o sintoma-diagnóstico da doença e que precede os sintomas da copa. As plantas enxertadas nas tangerinas Cleópatra e Sunki, no trifoliata e no citrumelo Swingle, não mostram sintomas da doença. A transmissão por borbulha e a evolução espacial sugerem que a morte súbita dos citros seja causada por patógeno transmitido por vetor alado. Com o objetivo de selecionar porta-enxertos tolerantes à doença, laranjeiras Valência enxertadas em 254 porta-enxertos foram plantadas em maio de 2003 e 2004 em solos onde foram erradicados pomares afetados pela morte súbita dos citros e próximos a pomares afetados pela doença. Em novembro de 2006, o sintoma-diagnóstico da doença estava presente em dez seleções de limão-Cravo: Santa Barbara red lime, Borneo red lime, Limão-Cravo Taquaritinga, Rangpur India C-26-1, Rangpur rose lemon, Rangpur Kusaie lime, Rangpur red lime D-33-40, Rangpur Egyptian lime, Rangpur lemon India e Japanshe citroen.

    Full Text Available This study describes the ultrastructural differences between the compound eyes of ch li/ch li and Ch/ch li honeybee queens. Heterozygous "limão" bees had an almost normal ultrastructural organization of the ommatidia, but there were some alterations, including small vacuoles in the crystalline cones and a loss of pigment by primary pigmentary cells. In homozygous bees many ommatidia had very deformed crystalline cones and there were some bipartite rhabdoma. There was a reduction in the amount of pigment in the primary and secondary pigmentary cells and receptor cells (retinulae of mutant eyes. However, the eyes of both heterozygous and homozygous queens had the same type of pigment granules. Certain membrane-limited structures containing pigment granules and electron-dense material appeared to be of lysosomal nature. Since these structures occurred in the retinular cells of mutant eyes, they were considered to be multivesicular bodies responsible for the reduction in rhabdom volume in the presence of light, as a type of adaptation to brightness. The reduction of pigment in the pigmentary and retinular cells and the morphological changes seen in the rhabdom of the ommatidia may originate visual deficiencies, which could explain the behavioral modifications reported for Apis mellifera queens with mutant eye color.Este estudo descreve as diferenças ultra-estruturais entre os olhos compostos de rainhas de abelhas de genótipo ch li/ch li e Ch/ch li. Foram registradas diferenças na organização do omatídeo e na pigmentação geral dos dois tipos de olhos.

    RationaleAlthough laser absorption spectrometry (LAS) instrumentation is easy to use, its incorporation into laboratory operations is not easy, owing to extensive offline manipulation of comma-separated-values files for outlier detection, between-sample memory correction, nonlinearity (δ-variation with water amount) correction, drift correction, normalization to VSMOW-SLAP scales, and difficulty in performing long-term QA/QC audits.MethodsA Microsoft Access relational-database application, LIMS (Laboratory Information Management System) for Lasers 2015, was developed. It automates LAS data corrections and manages clients, projects, samples, instrument-sample lists, and triple-isotope (δ17O, δ18O, and δ2H values) instrumental data for liquid-water samples. It enables users to (1) graphically evaluate sample injections for variable water yields and high isotope-delta variance; (2) correct for between-sample carryover, instrumental drift, and δ nonlinearity; and (3) normalize final results to VSMOW-SLAP scales.ResultsCost-free LIMS for Lasers 2015 enables users to obtain improved δ17O, δ18O, and δ2H values with liquid-water LAS instruments, even those with under-performing syringes. For example, LAS δ2HVSMOW measurements of USGS50 Lake Kyoga (Uganda) water using an under-performing syringe having ±10 % variation in water concentration gave +31.7 ± 1.6 ‰ (2-σ standard deviation), compared with the reference value of +32.8 ± 0.4 ‰, after correction for variation in δ value with water concentration, between-sample memory, and normalization to the VSMOW-SLAP scale.ConclusionsLIMS for Lasers 2015 enables users to create systematic, well-founded instrument templates, import δ2H, δ17O, and δ18O results, evaluate performance with automatic graphical plots, correct for δ nonlinearity due to variable water concentration, correct for between-sample memory, adjust for drift, perform VSMOW-SLAP normalization, and perform long-term QA/QC audits

    Full Text Available Human T-cell leukemia virus type I (HTLV-I is the etiological agent of adult T-cell leukemia (ATL. Our recent studies have shown that one important mechanism of HTLV-I-Mediated tumorigenesis is through PDZ-LIM domain-containing protein 2 (PDLIM2 repression, although the involved mechanism remains unknown. Here, we further report that HTLV-I-Mediated PDLIM2 repression was a pathophysiological event and the PDLIM2 repression involved DNA methylation. Whereas DNA methyltransferases 1 and 3b but not 3a were upregulated in HTLV-I-transformed T cells, the hypomethylating agent 5-aza-2′-deoxycytidine (5-aza-dC restored PDLIM2 expression and induced death of these malignant cells. Notably, the PDLIM2 repression was independent of the viral regulatory protein Tax because neither short-term induction nor long-term stable expression of Tax could downregulate PDLIM2 expression. These studies provide important insights into PDLIM2 regulation, HTLV-I leukemogenicity, long latency, and cancer health disparities. Given the efficient antitumor activity with no obvious toxicity of 5-aza-dC, these studies also suggest potential therapeutic strategies for ATL.

    The Baltic Sea is a seasonally ice-covered marginal sea in northern Europe with intense wintertime ship traffic and a sensitive ecosystem. Understanding and modeling the evolution of the sea-ice pack is important for climate effect studies and forecasting purposes. Here we present and evaluate the sea-ice component of a new NEMO-LIM3.6-based ocean-sea-ice setup for the North Sea and Baltic Sea region (NEMO-Nordic). The setup includes a new depth-based fast-ice parametrization for the Baltic Sea. The evaluation focuses on long-term statistics, from a 45-year long hindcast, although short-term daily performance is also briefly evaluated. We show that NEMO-Nordic is well suited for simulating the mean sea-ice extent, concentration, and thickness as compared to the best available observational data set. The variability of the annual maximum Baltic Sea ice extent is well in line with the observations, but the 1961-2006 trend is underestimated. Capturing the correct ice thickness distribution is more challenging. Based on the simulated ice thickness distribution we estimate the undeformed and deformed ice thickness and concentration in the Baltic Sea, which compares reasonably well with observations.

OBJETIVO: O objetivo do presente artigo é revisar evidências atuais acerca da efetividade das diversas abordagens farmacológicas empregadas como parte do plano de tratamento produzido para indivíduos que enfrentam essa doença. MÉTODOS: Para esse propósito, os autores revisaram o banco de dados MEDLINE em busca de ensaios clínicos publicados entre 1986 e 2003. Borderline personality disorder e clinical trials foram usados com descritores. RESULTADOS: Numerosos trabalhos foram encontrados, mas poucos estudos controlados estavam disponíveis. Notável é o fato de que virtualmente todas as classes de psicofármacos foram testadas nesse grupo de pacientes, comumente com desfechos modestos ou variáveis. Devido a limitações metodológicas na vasta maioria dos ensaios clínicos envolvendo drogas específicas nesse grupo de pacientes, foi difícil estimar o benefício real dos vários agentes testados. A evidência mais forte existe para os inibidores seletivos de serotonina, antipsicóticos e divalproato. DISCUSSÃO: Claramente, mais ensaios clínicos bem delineados são necessários, mas os dados revisados sugerem que psicofármacos são efetivos para tratar sintomas-alvo nesses pacientes. Conclui-se que psicotrópicos são adjuntos úteis às abordagens psicoterapêuticas usualmente empregadas para tratar pacientes limítrofes.INTRODUCCÍON: El trastorno de personalidad limítrofe (TPL es un síndrome psiquiátrico que causa significativa morbididad y mortalidad a pacientes internados y ambulatoriales tratados por profesionales de salud mental.

    Full Text Available El Caribe costarricense es importante como sitio de alimentación, copulación, anidación y desove de las tortugas marinas, por lo que el presente trabajo pretendió actualizar el patrón de anidación en las tortugas marinas Dermochelys coriacea y Eretmochelys imbricata en el sector Gandoca, del Refugio Nacional de Vida Silvestre Gandoca Manzanillo, Limón, Costa Rica, para proponer medidas de manejo. Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011, y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525. Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

    Full Text Available A área total irrigada em pomares cítricos no Brasil tem aumentado ao longo das décadas. A principal causa desse aumento deve-se ao uso de porta-enxertos tolerantes à Morte Súbita dos Citros, porém menos tolerantes à seca que o limão Cravo. Este trabalho tem como objetivo estudar a influência do porta-enxerto e do tipo de solo na transpiração de plantas jovens de laranjeira Valência. O experimento foi conduzido em estufa, nas dependências do Departamento de Engenharia de Biossistemas da ESALQ/USP. Mudas de laranjeira foram plantadas em caixas de 500 L. Determinou-se, simultaneamente, a transpiração de 20 plantas por meio de sondas de dissipação térmica (fluxo de seiva. Foram medidas a radiação solar global, a umidade relativa e a temperatura do ar com sensores instalados a 2 m de altura no centro da estufa. A evapotranspiração de referência (EToPM foi calculada pelo método de Penman-Monteith proposto pela FAO. De acordo com os resultados encontrados, conclui-se que a transpiração das plantas de laranjeira Valência é influenciada não só pelo tipo de porta-enxerto utilizado, como também pelo crescimento em área foliar e estádio fenológico, sendo que sua relação com a EToPM não é linear em toda a faixa de demanda evaporativa da atmosfera.

  5. Drosophila Model for the Analysis of Genesis of LIM-kinase 1-Dependent Williams-Beuren Syndrome Cognitive Phenotypes: INDELs, Transposable Elements of the Tc1/Mariner Superfamily and MicroRNAs

    Full Text Available Genomic disorders, the syndromes with multiple manifestations, may occur sporadically due to unequal recombination in chromosomal regions with specific architecture. Therefore, each patient may carry an individual structural variant of DNA sequence (SV with small insertions and deletions (INDELs sometimes less than 10 bp. The transposable elements of the Tc1/mariner superfamily are often associated with hotspots for homologous recombination involved in human genetic disorders, such as Williams Beuren Syndromes (WBS with LIM-kinase 1-dependent cognitive defects. The Drosophila melanogaster mutant agnts3 has unusual architecture of the agnostic locus harboring LIMK1: it is a hotspot of chromosome breaks, ectopic contacts, underreplication, and recombination. Here, we present the analysis of LIMK1-containing locus sequencing data in agnts3 and three D. melanogaster wild-type strains—Canton-S, Berlin, and Oregon-R. We found multiple strain-specific SVs, namely, single base changes and small INDEls. The specific feature of agnts3 is 28 bp A/T-rich insertion in intron 1 of LIMK1 and the insertion of mobile S-element from Tc1/mariner superfamily residing ~460 bp downstream LIMK1 3′UTR. Neither of SVs leads to amino acid substitutions in agnts3 LIMK1. However, they apparently affect the nucleosome distribution, non-canonical DNA structure formation and transcriptional factors binding. Interestingly, the overall expression of miRNAs including the biomarkers for human neurological diseases, is drastically reduced in agnts3 relative to the wild-type strains. Thus, LIMK1 DNA structure per se, as well as the pronounced changes in total miRNAs profile, probably lead to LIMK1 dysregulation and complex behavioral dysfunctions observed in agnts3 making this mutant a simple plausible Drosophila model for WBS.

    Environmental exposures filtered through the genetic make-up of each individual alter the transcriptional repertoire in organs central to metabolic homeostasis, thereby affecting arterial lipid accumulation, inflammation, and the development of coronary artery disease (CAD). The primary aim of the Stockholm Atherosclerosis Gene Expression (STAGE) study was to determine whether there are functionally associated genes (rather than individual genes) important for CAD development. To this end, two-way clustering was used on 278 transcriptional profiles of liver, skeletal muscle, and visceral fat (n =66/tissue) and atherosclerotic and unaffected arterial wall (n =40/tissue) isolated from CAD patients during coronary artery bypass surgery. The first step, across all mRNA signals (n =15,042/12,621 RefSeqs/genes) in each tissue, resulted in a total of 60 tissue clusters (n= 3958 genes). In the second step (performed within tissue clusters), one atherosclerotic lesion (n =49/48) and one visceral fat (n =59) cluster segregated the patients into two groups that differed in the extent of coronary stenosis (P=0.008 and P=0.00015). The associations of these clusters with coronary atherosclerosis were validated by analyzing carotid atherosclerosis expression profiles. Remarkably, in one cluster (n =55/54) relating to carotid stenosis (P =0.04), 27 genes in the two clusters relating to coronary stenosis were confirmed (n= 16/17, P<10 -27and-30). Genes in the transendothelial migration of leukocytes (TEML) pathway were overrepresented in all three clusters, referred to as the atherosclerosis module (A-module). In a second validation step, using three independent cohorts, the Amodule was found to be genetically enriched with CAD risk by 1.8-fold (P<0.004). The transcription co-factor LIM domain binding 2 (LDB2) was identified as a potential high-hierarchy regulator of the A-module, a notion supported by subnetwork analysis, by cellular and lesion expression of LDB2, and by the

    Full Text Available A atratividade da polpa do fruto de jatobá para saúva-limão foi avaliada tendo como parâmetro comparativo a polpa cítrica desidratada, utilizada como veículo por diversas marcas comerciais. O experimento foi conduzido em quatro formigueiros de saúva-limão em canteiros gramados com espécies arbóreas. As iscas de jatobá e de polpa cítrica desidratada, ambas sem princípio ativo, foram confeccionadas em grânulos com formato e diâmetro semelhantes aos das iscas granuladas comerciais. As iscas de jatobá foram mais atrativas para as operárias de saúva-limão, que fizeram o primeiro contato aos 17s, em contraste com os 29s gastos para o primeiro contato com as iscas de polpa cítrica. As iscas de jatobá também começaram a ser carregadas mais cedo, aos 26s, sendo que as iscas de polpa cítrica foram carregadas 48s mais tarde. A grande aceitação do jatobá foi reforçada pelo menor tempo para o encerramento dos testes, 5min 39s, contrastando com os 11min 17s necessários para o encerramento do teste com a polpa cítrica. A polpa do fruto do jatobá foi mais atrativa para saúva-limão do que a polpa cítrica desidratada.Attractiveness of the leaf-cutting ant, Atta sexdens rubropilosa to jatobá's fruit pulp was evaluated, having the dehydrated citrus pulp as comparative parameter, used as vehicle by several commercial brands. The experiment was conducted on four nests of leaf-cutting ants on lawns with arboreal species. Jatobá baits and dehydrated citric pulp both without active principle were made into granules with form and diameter similar to the commercial granulated baits. Jatobá baits were more attractive to the laborers of leaf-cutting ants which made the first contact after 17s, contrasting with 29s before the first contact with citric pulp baits. Jatobá baits were also carried earlier, after 26s, while citric pulp baits were carried 48s later. The great acceptance of jatobá baits was strengthened by the short time to

    Full Text Available Em época de escassez de néctar, pode-se fornecer ao enxame uma suplementação alimentar utilizando "açúcar invertido" que é obtido pela hidrólise da sacarose em meio ácido por aquecimento, formando uma mistura de glicose e frutose. O ácido normalmente utilizado em tal reação é o ácido cítrico, no entanto, diante da dificuldade de pequenos produtores apícolas em obterem tal produto comercialmente, uma alternativa seria substituí-lo pela utilização de suco de limões. Sendo assim, o objetivo deste trabalho foi quantificar a inversão da sacarose em dietas para operárias de Apis mellifera, empregando-se o ácido cítrico e sucos de limões. Prepararam-se 21 soluções aquosas de açúcar cristal na proporção de 100 g/100 mL, colocando-se em cada uma 1,0; 2,0; 3,0; 5,0; 10,0; 15,0 ou 20,0 mL de suco dos limões Galego [Citrus aurantifolia (C. Swingle], Tahiti [Citrus latifolia Tanaka] ou Cravo [Citrus limonia (L. Osbeck]. Além dessas, outras seis soluções aquosas de açúcar na mesma proporção foram preparadas adicionando-se 0,1; 0,16; 0,3; 0,5 e 0,7 g de ácido cítrico e uma para testemunha. Quantificou-se a inversão pelo método de Somogyi-Nelson. Para o limão Cravo foi encontrada a menor porcentagem de inversão. Em relação a adição de ácido cítrico, constatou-se que ao colocar 0,1 g, a inversão foi estimada em 12,2% enquanto que, com a adição de 0,16 g, a inversão seria de 18,8%. A quantidade máxima de ácido cítrico a ser adicionada foi estimada em 0,18 g adotando como critério o pH médio de 3,3 dos méis de abelhas africanizadas. Para os sucos dos limões Galego, Tahiti e Cravo, quando utilizados como substitutos do ácido cítrico, estimou-se a quantidade máxima a ser adicionada sendo igual a 2,1; 3,6 e 5,3 mL, respectivamente, para cada 100 g de açúcar em 100 mL de água, para o pH fixado em 3,3. Considerando-se a inversão e o pH, o suco do limão Tahiti forneceu melhores resultados.In times of

    Despite the financial crisis and the revisited 2007 prospects, the 2008 edition of the 'World Energy Outlook' (WEO-2008) of the International Energy Agency (OECD/IEA) foresees a regular increase of oil and gas demand. WEO-2008 draws on the experience of another turbulent year in energy markets to provide new energy projections to 2030, region by region and fuel by fuel. It incorporates the latest data and policies. WEO-2008 focuses on two pressing issues facing the energy sector today: - Prospects for oil and gas production: How much oil and gas exists and how much can be produced? Will investment be adequate? Through field-by-field analysis of production trends at 800 of the world's largest oil fields, an assessment of the potential for finding and developing new reserves and a bottom-up analysis of upstream costs and investment, WEO-2008 takes a hard look at future global oil and gas supply. - Post-2012 climate scenarios: What emissions limits might emerge from current international negotiations on climate change? What role could cap-and-trade and sectoral approaches play in moving to a low-carbon energy future? Two different scenarios are assessed, one in which the atmospheric concentration of emissions is stabilised at 550 parts per million (ppm) in CO 2 equivalent terms and the second at the still more ambitious level of 450 ppm. The implications for energy demand, prices, investment, air pollution and energy security are fully spelt out. This ground-breaking analysis will enable policy makers to distill the key choices as they strive to agree in Copenhagen in 2009 on a post-Kyoto climate framework. The good news in this energy outlook is that renewable energies will become in 2020 the second source of power generation

A sign of learning organisations are the many successful enterprises, and the abundance of new products and services that keeps emerging. The question about organisational learning...... made with reference to ideas of education, i.e. intentional processes of the production of knowledge. In this paper, I argue that learning and organisational learning does not primarily appear as a result of intended processes but often as the opposite, i.e. as a struggle to maintain the old and create...... new. The field of organisational learning has always reflected the current and contemporary understandings of the management of enterprises. This is the background for providing first a brief historic account of the organisational learning literature. I will introduce the most important trends...

    1999-01-01

    The problem of shutdown reactors is growing steadily. As of the beginning of 1999, 94 reactors have been shutdown, only 429 were in operation, meaning that one out of 5.5 reactors ever built was permanently closed. Yet only a handful of these have actually been dismantled. Some countries as Japan and USA, have announced their policies that hey plan to dismantle their reactors in a decade or two after closure. Other countries like Canada or France intend to wait several decades. At the extreme United Kingdom decided to wait more than 100 years. This old shutdown reactors could become a near permanent fixture in some countries. The problem is that, the longer the reactors run, the more radioactive their interiors become, the more difficult, dangerous and expensive is to dismantle the plants, to store and bury the residual radioactive waste. Despite some early real experience with the cost of decommissioning plants, it still remains uncertain just what those costs will be and who will pay. Estimates of the dismantling cost have ranged from 10% of the initial capital investment up to 40% and even 100%. Thus, decommissioning could become the largest remaining expense facing the nuclear industry and the governments who have supported it, particularly if efforts to confine radioactive waste fail. The challenge facing the human societies is to keep nuclear waste including the shuttered plants in isolation for the many millennia that make up the hazardous life of these materials. In this light, no matter what becomes of nuclear power, the nuclear age will continue for a very long time

    1984-01-01

    The book surveys the experience of the past decade concerning current international efforts to tackle the growing scarcity of wood to cook the food and warm the homes of the rural poor of the Third World. It draws a number of conclusions about firewood, soil-loss, population pressure and poverty: (1) firewood demand is not the main cause of tropical deforestation and soil erosion; (2) community forestry rarely provides fuel for the really poor, and may even make them worse off; (3) local participation is no guarantee that firewood will reach those who need it most, but without community support the woodlots will die; (4) even when fuel is scarce, people often prefer to plant trees for shade, timber, fruit or livestock fodder rather than for firewood; (5) improved cookstoves can make cooking more pleasant, healthier and safer, but they will not save forests and do not as yet save much fuel. The poor of the Third World need far more fuel than village woodlots can ever provide. Much more must be done to plant trees on farms, to get more wood from existing forests, and to promote energy alternatives, including coal and oil. It is concluded that, in the end, people are short of firewood because they are poor, and without development they will find no escape.

    Full Text Available Em função do grande volume de produção e comercialização do capim-limão, estima-se que uma contaminação microbiológica deste produto possa representar importante risco para a saúde pública. Esta pesquisa visou avaliar marcas de chá de capimlimão, em relação às qualidades microbiológica e físico-química, tendo como base alegislação brasileira do Ministério da Saúde. Nenhuma das amostras apresentou Salmonella sp., porém em 50% delas, houve presença de coliformes a 35ºC. Em três amostras, evidenciaram-se coliformes a 45ºC, com presença de Escherichia coli em uma destas. 81,25%das amostras apresentaram bolores e leveduras, porém sem relação direta com os teores de umidade observados. Dentre os fungos presentes, identificou-se Aspergillus niger, no entanto sem produção de aflatoxinas. Todos infusos analisados negativaram a contaminação evidenciada nos testes com o produto seco. Os resultados indicaram possíveis falhas nos procedimentos pós-colheita e de comercialização. A implementação do Sistema APPCC (HACCP poderia substancialmente minimizar esta contaminação.Considering the great volume of lemongrass production andcommercialization, it is estimated that a potential microbiological contamination of this product could represent an important hazard to public health.

Total dry weight, shoot P concentration and specific P uptake by roots increased in mycorrhizal plants with the doses of 25 and 200 mg kg-1 P at 90 DAT. With 1,000 mg kg-1 P, mycorrhizal plants had a transient growth depression at 90 and 120 DAT, and nonmycorrhizal effects on P uptake at any harvesting period. Root colonization and total external mycelium correlated positively with shoot P concentration and total dry weight at the two lowest P levels.

    On March 23, 2010, President Barack Obama signed the Patient Protection and Affordable Care Act (ACA) into law. As it went through Congress, the legislation faced forceful resistance. Individuals and organizations opposing the ACA circulated propaganda that varied from photographs of fresh graves or coffins with the caption "Result of ObamaCare" to portrayals of President Obama as the Joker from the Batman movies, captioned with the single word "socialism." The arguments embedded in these images have striking parallels to cartoons circulated by physicians to their patients in earlier fights against national health care. Examining cartoons used in the formative health care reform debates of the 1940s provides a means for tracing the lineage of emotional arguments employed against health care reform.

    Full Text Available This article assesses whether the antimajoritarian outcome in the 2012 US congressional elections was due more to deliberate partisan gerrymandering or asymmetric geographic distribution of partisans. The article first estimates an expected seats–votes slope by fitting past election results to a probit curve, and then measures how well parties performed in 2012 compared to this expectation in each state under various redistricting institutions. I find that while both parties exceeded expectations when controlling the redistricting process, a persistent pro-Republican bias is also present even when maps are drawn by courts or bipartisan agreement. This persistent bias is a greater factor in the nationwide disparity between seats and votes than intentional gerrymandering.

    2017-03-01

    In psychotherapy, therapist and patient influence each other constantly. We aimed to investigate how therapists respond to patient impression management and influence tactics. For 60 videotaped intake interviews, judges rated therapist responses to patient tactics as neutral, desired, or undesired from the patient perspective. Judges rated the therapist responses in 57% as neutral, in 40% as desired, and in 2% as undesired by the patients. The proportions of response outcomes varied across tactics. Therapist responses were unrelated to therapist and patient sex. Therapist experience was related to their responses to the tactic Supplication. Overall, some patient tactics seem to be more challenging for therapists than others. Awareness of such response tendencies can help therapists prepare their reactions to certain patient impression management and influence tactics. Implications for training and research are presented.

  6. Who decides who has won the bet? Total and Anthropogenic Warming Indices

    2016-12-01

    An extension of the idea of betting markets as a means of revealing opinions about future climate are climate policies indexed to geophysical indicators: for example, to ensure net zero global carbon dioxide emissions by the time anthropogenic warming reaches 1.5 degrees above pre-industrial, given about 1 degree of warming already, emissions must fall, on average, by 20% of their current value for every tenth of a degree of anthropogenic warming from now on. In principle, policies conditioned on some measure of attributable warming are robust to uncertainty in the global climate response: the risk of a higher or lower response than expected is borne by those affected by climate change mitigation policy rather than those affected by climate change impacts, as is the case with emission targets for specific years based on "current understanding" of the response. To implement any indexed policy, or to agree payout terms for any bet on future climate, requires consensus on the definition of the index: how is it calculated, and who is responsible for releasing it? The global mean surface temperature of the current decade relative to pre-industrial may vary by 0.1 degree or more depending on precisely what is measured, what is defined as pre-industrial, and the treatment of regions with sparse data coverage in earlier years. Indices defined using different conventions, however, are all expected to evolve very similarly over the coming decades, so agreeing on a conservative, traceable index such as HadCRUT is more important than debating the "true" global temperature. A more important question is whether indexed policies and betting markets should focus on total warming, including natural and anthropogenic drivers and internal variability, or an Anthropogenic Warming Index (AWI) representing an unbiased estimate of warming attributable to human influence to date. We propose a simple AWI based solely on observed temperatures and global natural and anthropogenic forcing estimates. It is much less volatile than total observed warming, which might discourage participation in betting markets, but would be a substantial advantage for indexed policies. It is also much more relevant to the UNFCCC goal of limiting anthropogenic warming to "well below" 2 degrees. The 2016 value for the AWI will be announced at AGU.

    New health information technology (HIT) increasingly plays a role in health care as technology becomes cheaper and more widespread. However, there is a danger that those who do not use or have access to technology will not benefit from HIT innovations, thus creating a "digital divide". To assess the extent to which mental health service users have access to, skills in using and appetite for various technologies. A cross-sectional survey was used to assess technology use and access patterns of 121 people from community mental health services. Data were analysed using logistic regression. Technology use and access were very similar to that of the general population with older individuals reporting less familiarity, access and confidence across a range of technologies. Black, minority and ethnic (BME) groups were more likely to access computers outside of their own homes than white individuals. Older participants experiencing psychosis indicated a desire to increase their computer use. The findings reported here contrast with recent evidence suggesting that those who do not engage with technology are "self-excluders". Furthermore, BME groups may need extra support regarding provision of technology in order to engage with HIT.

    Our objective was to investigate the hypothesis that women on adjuvant aromatase inhibitors (AIs) for treatment of breast cancer have a higher prevalence of dry eye syndrome (DES) compared with controls. Exposure and control groups were recruited. A cross sectional questionnaire-based study was performed. Demographic data and medical histories were collected. The presence of dry eye syndrome was determined by the ocular surface disease index (OSDI). The Functional Assessment of Cancer Treatment - Endocrine Subscale (FACT-ES) was performed to investigate correlations with other side effects of AIs. 93 exposure group and 100 control group questionnaires were included. The groups were similar in all demographic variables. The prevalence of dry eye syndrome was 35% (exposure) and 18% (control) (p dry eyes. The OSDI score was negatively correlated with the total FACT-ES score and positively correlated with duration of treatment. Our study is the first to use a validated questionnaire to assess for DES in this population. DES is significantly more prevalent in women on AIs compared with controls. This is a newly emerging, and easily treated side effect of AIs. Self-reporting of dry eye symptoms underestimates the prevalence of DES with AIs. We recommend routine screening of patients on AIs with the OSDI with the aim of improving patient quality of life and possibly adherence. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2011-06-01

    Full Text Available This paper explores the issue of structural breaks and long memory property in the conditional variance process of the Korean exchange rates. To analyze the above in detail, this paper examines the dynamics of the structural breaks and the long memory in the conditional variance process of the Korean exchange returns by using the daily KRW-USD and KRW-JPY exchange rates for the period from 2000 through 2007. In particular, this paper employs the Adaptive FIGARCH model of Baillie and Morana (2009 which account for the structural breaks and the long memory property together. This paper also finds that the new Adaptive FIGARCH model outperforms the usual FIGARCH model of Baillie et al. (1996 when the structural breaks are present and that the long memory property in the conditional variance process of the Korean exchange returns is significantly reduced after the structural breaks are accounted for. Thus, these results suggest that the upward biased long memory property observed in the conditional variance process of the Korean exchange returns could partially have been imparted as a result of neglecting the structural breaks.

    Group loyalty is highly valued. However, little is known about young children's loyal behavior. This study tested whether 4- and 5-year-olds (N=96) remain loyal to their group even when betraying it would be materially advantageous. Children and four puppets were allocated to novel groups. Two of these puppets (either in-group or out-group members) then told children a group secret and urged them not to disclose the secret. Another puppet (not assigned to either group) then bribed children with stickers to tell the secret. Across ages, children were significantly less likely to reveal the secret in the in-group condition than in the out-group condition. Thus, even young children are willing to pay a cost to be loyal to their group. Copyright © 2015 Elsevier Inc. All rights reserved.

    Environmentalists worry that hazardous wastes produced in industrialized nations are being dumped in cash-starved developing countries--the countries with the least political or economic clout to resist and the fewest resources for managing these toxic imports. Imported waste can pose a serious threat to the health of human populations and ecosystems if not managed appropriately. In 1989, the international community initiated efforts to reduce the flow of hazardous wastes from industrialized countries to developing countries by drafting a treaty known as the Basel Convention on the Control of Transboundary Wastes and their Disposal. The convention's mission is to strictly regulate the international transfer of hazardous wastes and to ensure that wastes are managed and disposed of in an environmentally sound manner. Although the United States supports the convention in theory, it remains the only industrialized country within the Organization for Economic Cooperation and Development yet to ratify it. However, legislation drafted by the Clinton administration that is soon to go before the 106th Congress could make the United States a party to the convention.

  14. There is no free won't: antecedent brain activity predicts decisions to inhibit.

    Directory of Open Access Journals (Sweden)

    Elisa Filevich

    Full Text Available Inhibition of prepotent action is an important aspect of self-control, particularly in social contexts. Action inhibition and its neural bases have been extensively studied. However, the neural precursors of free decisions to inhibit have hardly been studied. We asked participants to freely choose to either make a rapid key press in response to a visual cue, or to transiently inhibit action, and briefly delay responding. The task required a behavioural response on each trial, so trials involving inhibition could be distinguished from those without inhibition as those showing slower reaction times. We used this criterion to classify free-choice trials as either rapid or inhibited/delayed. For 13 participants, we measured the mean amplitude of the ERP activity at electrode Cz in three subsequent 50 ms time windows prior to the onset of the signal that either instructed to respond or inhibit, or gave participants a free choice. In two of these 50 ms time windows (-150 to -100, and -100 to -50 ms relative to action onset, the amplitude of prestimulus ERP differed between trials where participants "freely" chose whether to inhibit or to respond rapidly. Larger prestimulus ERP amplitudes were associated with trials in which participants decided to act rapidly as compared to trials in which they decided to delay their responses. Last-moment decisions to inhibit or delay may depend on unconscious preparatory neural activity.

    2009-03-01

    We present a case study of a child's psychological assessment using the methods of Therapeutic Assessment (TA). The case illustrates how TA can help assessors understand the process and structure of a family by highlighting how maladaptive family processes and interactions impact a child's development. It also illustrates how TA with a child can serve as a family intervention. In this case, it became apparent that the child's social difficulties were significant, not minor as initially reported by the parents, and were rooted in an insecure attachment, underlying depression, an idiosyncratic view of the world, and longing for attention, all of which were hidden or expressed in grandiose, expansive, and off-putting behaviors. In addition, the familial hierarchy was inverted; the parents felt ineffective and the child felt too powerful, leading to enhanced anxiety for the child. Intervention throughout, punctuated by the family session and feedback sessions, allowed the parents to develop a new "story" about their child and for the child to experience a new sense of safety. Following the TA, the parents and child indicated high satisfaction, enhanced family functioning, and decreased child symptomatology. Subsequent family therapy sessions allowed the family to further implement the interventions introduced in the TA.

    The British National Health Service (NHS) is undergoing possibly the most far-reaching set of changes in its sixty-five-year history. While some commentators (like Rudolf Klein) insist that little of substance is likely to change, others consider that the politics of reform may prove quite different on this occasion. The coalition government is committed to restructuring the welfare state and public services and to rolling back the state. The NHS as a popular monopoly public service runs counter to its neoliberal ideology. While (for now) remaining committed to a publicly funded system of health care that is largely free at point of use, the government wishes to encourage much greater diversity in the provision of care, including a much larger role for the for-profit private sector. Despite significant opposition to its proposals, few concessions have been forthcoming, and the legislation that passed onto the statute book in March 2012 remained essentially unchanged. Notwithstanding the lack of convincing evidence, the government is wedded to encouraging greater competition and choice. Thosewho believe the changes will amount to far less than its architects hope for are being too complacent and overlooking the strength of the government's ideological convictions. These threaten to dismantle the NHS and replace it with a more costly, fragmented, and less effective system of care that is driven by profit in place of the public interest.

    Roemer, R

    1968-09-12

    Family planning in Malaysia is discussed. Family planning began in Malaysia about 15 years ago through the efforts of voluntary family Planning Associations in the various Malay states. In 1966 the Malaysian Parliament passed the National Family Planning Act setting up the National FAmily Planning Board to formulate policies and methods for the promotion and spread of family planning knowledge and practice on the grounds of health of mothers and children and welfare of the family. In 1967, the board set a target of 40,000 new acceptors of family planning and 90% of the target was reached. This represents 3% of the child-bearing married women aged 15-49. The target for 1968 of 65,000 new acceptors is being achieved. A survey of acceptors is to be carried out from December 1968 to April 1969 to ascertain how many women who accepted family planning continue to practice it. Malaysia's crude birth rate declined from 46.2 in 1957 to 37.3 in 1966 before the government program was instituted. Abortion attempts have been frequent. The main method of contraception used is oral contraceptives. According to a 1957 survey, 31% of the married women in the metropolitan areas and 2% of rural women were using contraception. Presently, in Malaysia there is a need to: 1) train personnel to provide services, 2) inform and motivate families to accept family planning, 3) continue a broad educational program, 4) reform Malaysia's antiquated abortion law, and 5) integrate family planning services more fully into the general health services of the country.

    In this article we summarize benefits of delayed chest closure strategy in lung transplantation, addressing indications, different surgical techniques, and additional perioperative treatment. Delayed chest closure seems to be a valuable and safe strategy in managing patients with various conditions after lung transplantation, such as instable hemodynamics, need for high respiratory pressures, coagulopathy, and size mismatch. Therefore, this approach should be considered in lung transplant centers to give patients time to recover before the chest is closed.

    Energy Technology Data Exchange (ETDEWEB)

    Eckholm, E; Foley, G; Barnard, G; Timberlake, L

    1987-01-01

    The fuelwood crisis has seriously increased in gravity since the 1979s. In many developing countries firewood contributes to 90% of the total energy consumption. By the year 2000, 2.4 milliard people will be using firewood more quickly than the trees can grow to supply it. It is people stricken with poverty that will suffer most under this situation. Although since 1978-80, 500 million US dollars have been spent on community forest projects, many of them have not been succesful, and it is only recently that connections between the firewood crisis and deforestation, between supply and demand, have become clear. In most countries the forests disappear because the people need arable land to grow food from. Different methods of supporting tree planting projects are described, as well as ways of helping communal forestry to function satisfacorily. Ovens where much less fuel wood is needed to produce the correct heat temperatures, have been introduced in Africa, Asia and Latin America. Yet many of these ovens break down. When planning for the future, village tree plantations, the possibility of planting more trees on private gorunds, the more rationalised use of manure and farm wastes as fertilizers for trees, stricter price control and social reform, should all be kept in mind.

    Fawley, W M

    2001-01-01

    ICOOL is a Fortran77 macroparticle transport code widely used by researchers to study the front end of a neutrino factory/muon collider. In part due to the desire that ICOOL be usable over multiple computer platforms and operating systems, the code uses simple text files for input/output services. This choice together with user-driven requests for greater and greater choice of lattice element type and configuration has led to ICOOL input decks becoming rather difficult to compose and modify easily. Moreover, the lack of a standard graphical postprocessor has prevented many ICOOL users from extracting all but the most simple results from the output files. Here I present two attempts to improve this situation: First, a simple but quite general graphical pre-processor (NIME) written in the Tcl/TK to permit users to write and maintain ASCII-formatted input files by use of simple macro definitions and expansions. Second, an interactive postprocessor written in Fortran90 and NCAR graphics, which allows users to def...

  15. Applying the Helmholtz Illusion to Fashion: Horizontal Stripes Won't Make You Look Fatter

    Directory of Open Access Journals (Sweden)

    Peter Thompson

    2011-01-01

    Full Text Available A square composed of horizontal lines appears taller and narrower than an identical square made up of vertical lines. Reporting this illusion, Hermann von Helmholtz noted that such illusions, in which filled space seems to be larger than unfilled space, were common in everyday life, adding the observation that ladies' frocks with horizontal stripes make the figure look taller. As this assertion runs counter to modern popular belief, we have investigated whether vertical or horizontal stripes on clothing should make the wearer appear taller or fatter. We find that a rectangle of vertical stripes needs to be extended by 7.1% vertically to match the height of a square of horizontal stripes and that a rectangle of horizontal stripes must be made 4.5% wider than a square of vertical stripes to match its perceived width. This illusion holds when the horizontal or vertical lines are on the dress of a line drawing of a woman. We have examined the claim that these effects apply only for 2-dimensional figures in an experiment with 3-D cylinders and find no support for the notion that horizontal lines would be ‘fattening’ on clothes. Significantly, the illusion persists when the horizontal or vertical lines are on pictures of a real half-body mannequin viewed stereoscopically. All the evidence supports Helmholtz's original assertion.

    Today's case managers need far more than on-the-job training to understand the complexities of the job and all of the tasks they must do on a daily basis. The length and content of the training must be geared to individual case managers and take into account their knowledge, skill set and experience. New case managers should be able to pass competencies and should meet with the case manager director and the person doing the training at the end of the week to discuss how the training is going. Hospital case managers must develop their own case management training programs that are based on hospital procedures and policies, specific job descriptions, and goals of the department, some experts say. In many cases, rather than hiring an experienced case manager who may not fit well into your department, it's better to hire someone with the characteristics you are looking for and teach him or her case management.

    Directory of Open Access Journals (Sweden)

    Alexander Vaninsky

    2013-07-01

    Full Text Available This paper introduces a simplified version of Data Envelopment Analysis - a conventional approach to evaluating the performance and ranking of competitive objects characterized by two groups of factors acting in opposite directions: inputs and outputs. Examples of DEA applications discussed in this paper include the London 2012 Olympic Games and the dynamics of the United States’ environmental performance. In the first example, we find a team winner and rank the teams; in the second, we analyze the dynamics of CO2 emissions adjusted to the gross domestic product, population, and energy consumption. Adding a virtual Perfect Object – one having the greatest outputs and smallest inputs - we greatly simplify the DEA computational procedure by eliminating the Linear Programming algorithm. Simplicity of computations makes the suggested approach attractive for educational purposes, in particular, for use in Quantitative Reasoning courses.

  4. Out-of-sample Forecasting Performance of Won/Dollar Exchange Rate Return Volatility Model

    Directory of Open Access Journals (Sweden)

    Hojin Lee

    2009-06-01

    Full Text Available We compare the out-of-sample forecasting performance of volatility models using daily exchange rate for the KRW/USD during the period from 1992 to 2008. For various forecasting horizons, historical volatility models with a long memory tend to make more accurate forecasts. Especially, we carefully observe the difference between the EWMA and the GARCH(1,1 model. Our empirical finding that the GARCH model puts too much weight on recent observations relative to those in the past is consistent with prior evidence showing that asset market volatility has a long memory, such as Ding and Granger (1996. The forecasting model with the lowest MSFE and VaR forecast error among the models we consider is the EWMA model in which the forecast volatility for the coming period is a weighted average of recent squared return with exponentially declining weights. In terms of forecast accuracy, it clearly dominates the widely accepted GARCH and rolling window GARCH models. We also present a multiple comparison of the out-of-sample forecasting performance of volatility using the stationary bootstrap of Politis and Romano (1994. We find that the White's reality check for the GARCH(1,1 expanding window model and the FIGARCH(1,1 expanding window model clearly reject the null hypothesis and there exists a better model than the two benchmark models. On the other hand, when the EWMA model is the benchmark, the White's for all forecasting horizons are very high, which indicates the null hypothesis may not be rejected. The Hansen's report the same results. The GARCH(1,1 expanding window model and the FIGARCH(1,1 expanding window model are dominated by the best competing model in most of the forecasting horizons. In contrast, the RiskMetrics model seems to be the most preferred. We also consider combining the forecasts generated by averaging the six raw forecasts and a trimmed set of forecasts which calculate the mean of the four forecasts after disregarding the highest and lowest forecasts from the six models. This experiment confirms that the forecast combinations always outperform forecasts from a single model.

    2000-01-01

    The current mission of the Savannah River Site is focused primarily on cleanup and disposal of waste associated with more than 40 years of nuclear material production. However, SRS continues to provide tritium processing for the Department of Energy. Tritium, a radioactive isotope of hydrogen gas, is used to boost the explosive power of nuclear weapons. The tritium container, processed by SRS, is known as a reservoir. Part of the SRS tritium mission is to assure the safety and reliability of tritium reservoirs by conducting a series of thorough surveillance tests on a sampling of fielded reservoirs. Data from these tests have historically been stored in a database archive and reporting system known as QUADSTAR. This system was developed at the Mound Facility in the mid-1980s when Mound performed the reservoir surveillance mission for DOE. The surveillance mission and the QUADSTAR database were transferred to SRS during the downsizing of the Nuclear Weapon Complex in the mid-1990s

    Machina, Hari K; Wild, David J

    2013-04-01

    There are technologies on the horizon that could dramatically change how informatics organizations design, develop, deliver, and support applications and data infrastructures to deliver maximum value to drug discovery organizations. Effective integration of data and laboratory informatics tools promises the ability of organizations to make better informed decisions about resource allocation during the drug discovery and development process and for more informed decisions to be made with respect to the market opportunity for compounds. We propose in this article a new integration model called ELN-centric laboratory informatics tools integration.

    Four sampling stations were set 200-500 m off Limon Port, Costa Rica, at an average depth of 20 m. From October 1996 to May 1997 horizontal subsuperficial trawls were done for 12 minutes at a speed of about 2 Km/h, with a 1,000 microns plancton net. A total of 28 samples were processed and 104 physical-chemistry parameter measurements were taken. Average salinity was 30.1 +/- 3.7 and dissolved oxygen 6.9 +/- 0.6 mg l-1 reflecting good aeration throughout the sampling period. This suggests good mixture and a highly dynamic hydrography. Temperature showed no drastic variations (28.0 +/- 1.7 degrees C), possibly because of the constant mixing with shallow water. The highest larval counts were for November and early January and include families common to reefs and estuaries (Balistidae, Lutjanidae) and to coastal areas (Centropomidae, Gerreidae, Haemulidae, Carangidae, Engraulidae, Hemiramphidae, and representative Pleuronectiformes) existing in a common area.

    Full Text Available The spread of Islam in Indonesia is closely related to the activity of Arabic language learning. As a code of linguistic expressions in learning Islam, the first aim in learning Arabic language in Indonesia is to fulfill people’s need in praying. In the second phase, Arabic language learning developed at many Islamic Boarding Schools. There was awareness that Arabic language was not only a tool in understanding a text, but also a tool for communication. It makes many people, especially those who studied abroad in the Middle East, motivated to innovate in the education development such as finding new concept and new teaching method especially in Arabic language teaching. In the third phase, Arabic language learning is nowadays used in a formal education and it is still in the process of completion of its curriculum, learning objective, learning material, teaching method, and its teaching media used in the teaching and learning process.

  16. Problems in the study of the medieval heritage in the Lim valley

    Directory of Open Access Journals (Sweden)

    Popović Marko

    2005-01-01

    Full Text Available Discussing the results of archaeological investigation at two important medieval sites - remains of the monastery of St George at Mažići near Priboj and of the church at Drenova near Prijepolje - the author puts forward his critical observations that make significant revisions to the conclusions suggested by excavators. The remains of a monastery at Mažići have long ago been identified with the monastery of St George in the župa (district of Dabar known from early 13th-century records. In the 1310s a monastery of St George is referred to in association with the toponym of Orahovica. After a long gap, the monastery is referred to again several times in the 1600s until its final destruction in 1743, as St George’s at Orahovica or simply Mažić(i. The report following systematic archaeological excavations suggests the unacceptable and unfounded conclusion, with dating and interpretation that the monastery church was built in the 13th century, received additions in the 14th, and was renovated in the 16th-17th centuries when there was a hospital attached to it. Careful analysis of the structural remains and the site’s stratigraphy clearly shows that the monastery was built on the site of a medieval cemetery of a 14th-15th-century date, which means that the church and its buildings cannot be older than the 16th century. The author also argues against the assumed presence of a monastic hospital, the assumption being based upon metal artifacts misinterpreted as "medical instruments" (parchment edge trimmer, compasses, fork!!!. The author’s inference is that the ruins at Mažići are not the remains of the monastery of St George, which should be searched for elsewhere, but possibly the legacy of a 14th-century monastic establishment which was moved there from an as yet unknown location most likely about the middle of the 16th century. The site at Drenova, with remains of a church destroyed by land slide, has been known since the late 19th century when a stone block was found there bearing the opening part of an inscription: "+ Te Criste auctore pontifex...", long believed to date from the 9th-10th century. Following the excavations, but based on this dating the church remains were interpreted as pre- Romanesque, and the interpretation entailed some major historical conclusions. From a more recent and careful analysis, the inscription has been correctly dated to the 6th century. With this dating as his starting-point, the author examines the fieldwork results and suggests that the block is an early-Byzantine spolium probably from the late-antique site of Kolovrat near Prijepolje, reused in the medieval period as a tombstone in the churchyard, where such examples are not lonely. It follows that the inscribed block is not directly relatable to the church remains and that it cannot be used as dating evidence. On the other hand, the church remains show features of the Romanesque-Gothic style of architecture typical of the Pomorje, the Serbian Adriatic coast. According to close analogies found for some elements of its stone decoration, the date of the church could not precede the middle of the 13th century. The question remains open as to who had the church built and what its original function was, that is whether a monastic community center round it. Its founder may be sought for among members of the ruling Nemanjić house, but a church dignitary cannot be ruled out. Anumber of complex issues raised by this site are yet to be resolved, but the study should be relieved of earlier misconceptions. Fresh information about this ruined medieval church should be provided by revision excavations in the future.

    Increasingly, the experiences and perceptions of parents who decline vaccination are the subject of investigation. However, the experiences of clinicians who encounter these parents in the course of their work has received little academic attention to date. This study aimed to understand the challenges faced and strategies used when general practitioners and immunising nurses encounter parents who choose not to vaccinate their children. Primary care providers were recruited from regions identified through the Australian Childhood Immunisation Register (ACIR) as having higher than national average rates of registered objection to childhood vaccination. Interviews began with an exploration of provider experiences with parents who accept, are hesitant towards, and who decline vaccination. Participants were asked specifically about how they addressed any difficulties they encountered in their interactions. Thematic analysis focused on encounters with parents - challenges and strategies. Twenty-six general practitioners (GPs), community and practice nurses (PNs) were interviewed across two regions in NSW, Australia. Providers' sense of professional identity as health advocates and experts became conflicted in their encounters with vaccine objecting parents. Providers were dissatisfied when such consultations resulted in a 'therapeutic roadblock' whereby provider-parent communication came to a standstill. There were mixed views about being asked to sign forms exempting parents from vaccinating their children. These ranged from a belief that completing the forms rewarded parents for non-conformity to seeing it as a positive opportunity for engagement. Three common strategies were employed by providers to navigate through these challenges; 1) to explore and inform, 2) to mobilise clinical rapport and 3) to adopt a general principle to first do no harm to the therapeutic relationship. Many healthcare providers find consultations with vaccine objecting parents challenging and some, particularly more experienced providers, employ successful strategies to address this. Primary care providers, especially those more junior, could benefit from additional communication guidance to better the outcome and increase the efficiency of their interactions with such parents.

  2. There's More to Groove than Bass in Electronic Dance Music: Why Some People Won't Dance to Techno.

    Brian C Wesolowski

    Full Text Available The purpose of this study was to explore the relationship between audio descriptors for groove-based electronic dance music (EDM and raters' perceived cognitive, affective, and psychomotor responses. From 198 musical excerpts (length: 15 sec. representing 11 subgenres of EDM, 19 low-level audio feature descriptors were extracted. A principal component analysis of the feature vectors indicated that the musical excerpts could effectively be classified using five complex measures, describing the rhythmical properties of: (a the high-frequency band, (b the mid-frequency band, and (c the low-frequency band, as well as overall fluctuations in (d dynamics, and (e timbres. Using these five complex audio measures, four meaningful clusters of the EDM excerpts emerged with distinct musical attributes comprising music with: (a isochronous bass and static timbres, (b isochronous bass with fluctuating dynamics and rhythmical variations in the mid-frequency range, (c non-isochronous bass and fluctuating timbres, and (d non-isochronous bass with rhythmical variations in the high frequencies. Raters (N = 99 were each asked to respond to four musical excerpts using a four point Likert-Type scale consisting of items representing cognitive (n = 9, affective (n = 9, and psychomotor (n = 3 domains. Musical excerpts falling under the cluster of "non-isochronous bass with rhythmical variations in the high frequencies" demonstrated the overall highest composite scores as evaluated by the raters. Musical samples falling under the cluster of "isochronous bass with static timbres" demonstrated the overall lowest composite scores as evaluated by the raters. Moreover, music preference was shown to significantly affect the systematic patterning of raters' responses for those with a musical preference for "contemporary" music, "sophisticated" music, and "intense" music.

    In October 1990, the Massachusetts Department of Public Health released their Southeastern Massachusetts health study. This is a study of leukemia incidence in 22 towns around Pilgrim NPP, for the period 1978 through 1986. Pilgrim Station had been returned to operation following a 3 year outage, from 1986-1989. During this period, some $300 million in capital outlay was invested by Boston Edison in upgrading safety systems and installing the so-Called Three Mile Island upgrades. A copy of the peer review panel report is attached to this paper. Because of the interest in the Southeastern Massachusetts Health Study in Europe. There are three major points the Panel made which can summarized: 1. No excess of leukemia was found around Pilgrim Station. 2. The Southeastern Massachusetts Health Study over-predicted by a factor of 90 the number of leukemia cases attributable to plant operation. 3. The Southeastern Massachusetts Health Study failed to account for exposure to natural background radiation, which represents far larger biological exposure than plant Operation. Given All Of This, One Might Ask Why Didn't Common Sense Prevail In The Beginning? One Answer Might Be The Energy Of The Media In Pursuing The Story And Playing It Up No Matter What.

  5. I Want to but I Won't: Pluralistic Ignorance Inhibits Intentions to Take Paternity Leave in Japan

    Full Text Available The number of male employees who take paternity leave in Japan has been low in past decades. However, the majority of male employees actually wish to take paternity leave if they were to have a child. Previous studies have demonstrated that the organizational climate in workplaces is the major determinant of male employees' use of family-friendly policies, because males are often stigmatized and fear receiving negative evaluation from others. While such normative pressure might be derived from prevailing social practices relevant to people's expectation of social roles (e.g., “Men make houses, women make homes”, these social practices are often perpetuated even after the majority of group members have ceased to support them. The perpetuation of this unpopular norm could be caused by the social psychological phenomenon of pluralistic ignorance. While researches have explored people's beliefs about gender roles from various perspectives, profound understanding of these beliefs regarding gender role norms, and the accuracy of others' beliefs remains to be attained. The current research examined the association between pluralistic ignorance and the perpetually low rates of taking paternity leave in Japan. Specifically, Study 1 (n = 299 examined Japanese male employees' (ages ranging from the 20 s to the 40 s attitudes toward paternity leave and to estimate attitudes of other men of the same age, as well as behavioral intentions (i.e., desire and willingness to take paternity leave if they had a child in the future. The results demonstrated that male employees overestimated other men's negative attitudes toward paternity leave. Moreover, those who had positive attitudes toward taking leave and attributed negative attitudes to others were less willing to take paternity leave than were those who had positive attitudes and believed others shared those attitudes, although there was no significant difference between their desires to take paternity leave. Study 2 (n = 425 replicated these results and further indicated that they could not be explained by the participants' needs to be socially desirable. Together, our findings suggest that pluralistic ignorance occurs in the context of taking paternity leave in Japanese men, and this leads to the low use of available paternity leave.

    2016-12-01

    Full Text Available Sir Geoffrey Hill, long hailed as Britain’s greatest living poet, was devoted to remembering the deceased, those forgotten in the debased din of mass culture—some of them worthy of our emulation, others edifying by their “folly” or “criminality” (Paris Review interview. Hill’s recent death, on 30 June 2016, presents an apt time to remember his own life-work. In its act of memorial as homage, The Mystery of the Charity of Charles Péguy marks a departure for Hill: whereas his earlier work often rests in ambiguity, Péguy labors through the ambiguity—through characteristically antiphonal tones of voice, rhythms, and images—and concludes in affirmation, a note of hope, which points in the direction of some of his later work. Through all of his complexity, Péguy’s life—like Hill’s poem—conforms to a kenotic, Christological pattern and is thus worthy of our emulation.

    Secretion is widespread in all eukaryotic cells: all of us experience this in the course of daily life--saliva, mucus, sweat, tears, bile juice, adrenalin, etc.--the list is extremely long. How does a cell manage to repeatedly spit out some stuff without losing the rest? The answer is: through regulated vesicle trafficking within the cell. The Nobel Prize in Physiology or Medicine 2013 was awarded to Drs Randy Schekman, James E Rothman and Thomas C Südhof for their 'discoveries of machinery regulating vesicle traffic, a major transport system in our cells'. Dr Randy Schekman and his colleagues discovered a number of genes required for vesicle trafficking from the endoplasmic reticulum (ER) and Golgi; the James E Rothman group unravelled the protein machinery that allows vesicles to bud off from the membrane and fuse to their targets; and Dr Thomas C Südhof along with his colleagues revealed how calcium ions could instruct vesicles to fuse and discharge their contents with precision. These enabled the biotechnology industry to produce a variety of pharmaceutical and industrial products like insulin and hepatitis B vaccines, in a cost-efficient manner, using yeast and tissue cultured cells.

  10. Simulation Suggests that medical group mergers won't undermine the potential utility of health information exchanges.

    Federal and state agencies are investing substantial resources in the creation of community health information exchanges, which are consortia that enable independent health care organizations to exchange clinical data. However, under pressure to form accountable care organizations, medical groups may merge and support private health information exchanges. Such activity could reduce the potential utility of community exchanges-that is, the exchanges' capacity to share patient data across hospitals and physician practices that are independent. Simulations of care transitions based on data from ten Massachusetts communities suggest that there would have to be many such mergers to undermine the potential utility of health information exchanges. At the same time, because hospitals and the largest medical groups account for only 10-20 percent of care transitions in a community, information exchanges will still need to recruit a large proportion of the medical groups in a given community for the exchanges to maintain their usefulness in fostering information exchange across independent providers.

    2018-05-01

    The question of whether tools erase cognitive and physical interindividual differences has been surprisingly overlooked in the literature. Yet if technology is profusely available in a near or far future, will we be equal in our capacity to use it? We sought to address this unexplored, fundamental issue, asking 200 participants to perform 3 physical (e.g., fine manipulation) and 3 cognitive tasks (e.g., calculation) in both non-tool-use and tool-use conditions. Here we show that tools do not erase but rather extend our intrinsic physical and cognitive skills. Moreover, this phenomenon of extension is task specific because we found no evidence for superusers, benefitting from the use of a tool irrespective of the task concerned. These results challenge the possibility that technical solutions could always be found to make people equal. Rather, technical innovation might be systematically limited by the user's initial degree of knowledge or skills for a given task. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

  12. Marooned no more : Newfoundland company hopes new technology means discovery won't be left high and dry

    Stranded gas currently makes up between 30 and 80 per cent of proven and potential natural gas reserves. Stranded gas is too remote from markets to be transported via pipeline, and is too small to justify costly liquefied natural gas (LNG) or gas-to-liquids infrastructure. However, emerging gas-to-wire technology may monetize an oil and gas discovery owned by Canadian Imperial Venture Corporation that is secluded on the west side of Newfoundland. Gas-to-wire technology involves generating power at the point of extraction to eliminate transportation costs. The wellsite is located within half a kilometre of the electricity grid. The gas-to-wire solution was proposed by ENEGI, a company that has developed software capable of analyzing multiple development options for stranded gas fields; probabilisitically estimating the risks and returns of a potential investment; and selecting the development plan that maximizes the value of a project. Factors such as recoverable reserves, gas flow rate, price of electricity, the distance to the nearest grid entry-point and the type of generating technology are considered to assess whether a field or group of fields may be suitable for gas-to-wire technology. The software provides detailed analysis of the key economic decision-making criteria through cash-flow analysis and the effect of different financing strategies on future balance sheets. The ENEGI knowledge base has a number of associated models consisting of a collection of algorithms with associated sets of data. ENEGI intends to use its scoping capability to identify suitable stranded gas assets and to demonstrate the value that may be added through a gas-to-wire solution. A recent detailed study conducted by the company has suggested that gas-to-wire may be a profitable option for many stranded gas fields. 2 figs

    In this paper, we extend the concept of the contrast sensitivity function - used to evaluate video projectors - to the evaluation of haptic devices. We propose using human observers to determine if vibrations rendered using a given haptic device are accompanied by artifacts detectable to humans. This determination produces a performance measure that carries particular relevance to applications involving texture rendering. For cases in which a device produces detectable artifacts, we have developed a protocol that localizes deficiencies in device design and/or hardware implementation. In this paper, we present results from human vibration detection experiments carried out using three commercial haptic devices and one high performance voice coil motor. We found that all three commercial devices produced perceptible artifacts when rendering vibrations near human detection thresholds. Our protocol allowed us to pinpoint the deficiencies, however, and we were able to show that minor modifications to the haptic hardware were sufficient to make these devices well suited for rendering vibrations, and by extension, the vibratory components of textures. We generalize our findings to provide quantitative design guidelines that ensure the ability of haptic devices to proficiently render the vibratory components of textures.

    Three misconceptions about working women are (1) they have lower self-confidence and organizational commitment; (2) they choose family over career; and (3) they do not have the same leadership skills as men. Changes that will not work to alter sex segregation are affirmative action, gender training, and seeding. (SK)

    Absract OBJECTIVES: To evaluate the relationship between Emergency Physician (EP) productivity and patient satisfaction with Emergency Department (ED) care. This retrospective observational study linked administrative and patient experience databases to measure correlations between the patient experience and EP productivity. The study was performed across three Calgary EDs (from June 2010 to July 2013). Patients>16 years old with completed Health Quality Council of Alberta (HQCA) ED Patient Experience Surveys were included. EP productivity was measured at the individual physician level and defined as the average number of patients seen per hour. The association between physician productivity and patient experience scores from six composite domains of the HQCA ED Patient Experience Survey were examined using Pearson correlation coefficients, linear regression modelling, and a path analysis. We correlated 3,794 patient experience surveys with productivity data for 130 EPs. Very weak non-significant negative correlations existed between productivity and survey composites: "Staff Care and Communication" (r=-0.057, p=0.521), "Discharge Communication" (r=-0.144, p=0.102), and "Respect" (r=-0.027, p=0.760). Very weak, non-significant positive correlations existed between productivity and the composite domains: "Medication Communication" (r=0.003, p=0.974) and "Pain management" (r=0.020, p=0.824). A univariate general linear model yielded no statistically significant correlations between EP productivity and patient experience, and the path analysis failed to show a relationship between the variables. We found no correlation between EP productivity and the patient experience.

    Involvement in creating antialcohol advertisements generates enthusiasm among adolescents; however, little is known about the messages adolescents develop for these activities. In this article, we present a content analysis of 72 print alcohol counteradvertisements created by high school (age 14-17 years old) and college (18-25 years old) students. The posters were content analyzed for poster message content, persuasion strategies, and production components, and we compared high school and college student posters. All of the posters used a slogan to highlight the main point/message of the ad and counterarguments/consequences to support the slogans. The most frequently depicted consequences were negative consequences of alcohol use, followed by negative-positive consequence comparison. Persuasion strategies were sparingly used in advertisements and included having fun/one of the gang, humor/unexpected, glamour/sex appeal, and endorsement. Finally, posters displayed a number of production techniques including depicting people, clear setting, multiple colors, different font sizes, and object placement. College and high school student-constructed posters were similar on many features (e.g., posters displayed similar frequency of utilization of slogans, negative consequences, and positive-negative consequence comparisons), but were different on the use of positive consequences of not using alcohol and before-after comparisons. Implications for teaching media literacy and involving adolescents and youth in developing alcohol prevention messages are discussed.

    Familiar items are found faster than unfamiliar ones in visual search tasks. This effect has important implications for cognitive theory, because it may reveal how mental representations of commonly encountered items are changed by experience to optimize performance. It remains unknown, however, whether everyday items with moderate levels of exposure would show benefits in visual search, and if so, what kind of experience would be required to produce them. Here, we tested whether familiar product logos were searched for faster than unfamiliar ones, and also familiarized subjects with previously unfamiliar logos. Subjects searched for preexperimentally familiar and unfamiliar logos, half of which were familiarized in the laboratory, amongst other, unfamiliar distractor logos. In three experiments, we used an N-back-like familiarization task, and in four others we used a task that asked detailed questions about the perceptual aspects of the logos. The number of familiarization exposures ranged from 30 to 84 per logo across experiments, with two experiments involving across-day familiarization. Preexperimentally familiar target logos were searched for faster than were unfamiliar, nonfamiliarized logos, by 8 % on average. This difference was reliable in all seven experiments. However, familiarization had little or no effect on search speeds; its average effect was to improve search times by 0.7 %, and its effect was significant in only one of the seven experiments. If priming, mere exposure, episodic memory, or relatively modest familiarity were responsible for familiarity's effects on search, then performance should have improved following familiarization. Our results suggest that the search-related advantage of familiar logos does not develop easily or rapidly.

    Dourley, John P

    2007-06-01

    White's Thomism and its Aristotelian foundation were at the heart of his differences with Jung over the fifteen years of their dialogue. The paper examines the precedents and consequences of the imposition of Thomism on the Catholic Church in 1879 in order to clarify the presuppositions White carried into his dialogue with Jung. It then selects two of Jung's major letters to White to show how their dialogue influenced Jung's later substantial work, especially his Answer to Job. The dialogue with White contributed to foundational elements in the older Jung's development of his myth which simply outstripped White's theological imagination and continues to challenge the worlds of contemporary monotheistic orthodoxy in all their variants.

    2016-06-01

    This paper reports on a quasi-experiment in which quantitative methods (QM) are embedded within a substantive sociology module. Through measuring student attitudes before and after the intervention alongside control group comparisons, we illustrate the impact that embedding has on the student experience. Our findings are complex and even contradictory. Whilst the experimental group were less likely to be distrustful of statistics and appreciate how QM inform social research, they were also less confident about their statistical abilities, suggesting that through 'doing' quantitative sociology the experimental group are exposed to the intricacies of method and their optimism about their own abilities is challenged. We conclude that embedding QM in a single substantive module is not a 'magic bullet' and that a wider programme of content and assessment diversification across the curriculum is preferential.

    Queue scheduled observations were carried out on 2015 April 1 and November 24 with the multi-object high resolution echelle spectrograph Hectochelle attached to the 6.5m telescope of the MMT observatory. The resolving power of the spectrograph (R~34,000) is high enough to detect the LiI λ6708 resonance doublet with little blending from adjacent metallic lines. The multi-object capability allowed us to simultaneously obtain 240 target and sky spectra in a single observation. The OB 26 filter transmits the wavelength range 6530-6715Å, and therefore the useful spectral features Hα λ6563 and HeI λ6678 could also be observed along with the LiI λ6708 line. The spectra of a total of 134 PMS stars were taken in two sets of exposure times -8 minutes x3 for bright stars (V<13.6mag) and 30 minutes x3 for fainter stars. Offset sky spectra were also obtained to correct for the contributions of locally variable nebula emission lines to the spectra of the faint stars. Calibration frames, such as dome flat and comparison spectra, were also acquired, just before and after the target exposure. (1 data file).

  18. Argonaute Utilization for miRNA Silencing Is Determined by Phosphorylation-Dependent Recruitment of LIM-Domain-Containing Proteins

    Directory of Open Access Journals (Sweden)

    Katherine S. Bridge

    2017-07-01

    Full Text Available As core components of the microRNA-induced silencing complex (miRISC, Argonaute (AGO proteins interact with TNRC6 proteins, recruiting other effectors of translational repression/mRNA destabilization. Here, we show that LIMD1 coordinates the assembly of an AGO-TNRC6 containing miRISC complex by binding both proteins simultaneously at distinct interfaces. Phosphorylation of AGO2 at Ser 387 by Akt3 induces LIMD1 binding, which in turn enables AGO2 to interact with TNRC6A and downstream effector DDX6. Conservation of this serine in AGO1 and 4 indicates this mechanism may be a fundamental requirement for AGO function and miRISC assembly. Upon CRISPR-Cas9-mediated knockout of LIMD1, AGO2 miRNA-silencing function is lost and miRNA silencing becomes dependent on a complex formed by AGO3 and the LIMD1 family member WTIP. The switch to AGO3 utilization occurs due to the presence of a glutamic acid residue (E390 on the interaction interface, which allows AGO3 to bind to LIMD1, AJUBA, and WTIP irrespective of Akt signaling.

    Full Text Available El uso de plaguicidas en los países en desarrollo es extenso en cantidad y en tiempo. Un gran porcentaje de lo que se aplica queda en el entorno y en los organismos que ahí habitan, lo que acarrea problemas de contaminación ambiental y deterioro de la salud de las personas que están en contacto con ellos. Los efectos se pueden manifestar a corto o a largo plazo y los síntomas varían desde un dolor de cabeza hasta el desarrollo de cáncer. La mayoría de los estudios en esta área se han orientado hacia los efectos agudos o crónicos y recientemente se inicia el estudio del efecto genotóxico de los plaguicidas. En e1 presente trabajo se evaluó el efecto genotóxico de los plaguicidas utilizados en las empacadoras de banano, usando como marcador biológico la electroforesis de células únicas (conocido como ensayo cometa en linfocitos aislados de sangre periférica. La población en estudio correspondió a 30 trabajadoras expuestas a plaguicidas, procedentes de 15 fincas bananeras y 28 mujeres sin antecedentes de exposición ocupacional a plaguicidas, de la misma área geográfica. Las trabajadoras que tenían entre cinco y quince años de trabajo presentaron mayor daño en la hebra sencilla del ADN (R² =0.12. Se desconoce si este efecto se debe a los plaguicidas que se utilizan actualmente o a plaguicidas empleados en el pasado. Tampoco fue posible correlacionar las dosis y las frecuencias de exposición a los plaguicidas con el daño al ADN, debido a que no existe un registro histórico sobre los productos empleados en el cultivo de banano, no se sabe por cuánto tiempo y las épocas en que fueron utilizados. Se recomienda el ensayo cometa para monitoreo genético en poblaciones expuestas a plaguicidasPesticide use in Costa Rica is very high and all year round. A high percentage of what is sprayed remains in the environment and in the living organisms around. This situation brings contamination and health problems to people in contact with them. The onset of adverse effects may be in the short or the long term, and symptoms vary widely, from headaches to cancer. Much research in this area has been devoted to acute or chronic effects, and not until recently to the genotoxic effect of pesticides. This study evaluated the genotoxic effect of pesticides used in banana packing activities, using the comet assay (single cell electrophoresis as the biological marker in lymphocytes. This was a case-control double blind study of 30 exposed women from 15 banana farms and 28 women not occupationally exposed to pesticides from the same geographic area. Results show damage to single stranded DNA after working from 5 to 15 years (R 2 =0.12. In Costa Rica we do not have an historical record of the kind of pesticides used in banana farms, the period of time and for how long were they used. This prevented further analysis concerning dose, frequency of exposure and use of new or old kind of pesticides in the farms in relation to DNA damage. The comet assay is of value in the genetic monitoring of pesticide exposed populations

  4. We Made Your Bed, Why Won't You Lie in It? Food Availability and Disease May Affect Reproductive Output of Reintroduced Frogs.

    Directory of Open Access Journals (Sweden)

    Kaya Klop-Toker

    Full Text Available Mitigation to offset the impacts of land development is becoming increasingly common, with reintroductions and created habitat programs used as key actions. However, numerous reviews cite high rates of poor success from these programs, and a need for improved monitoring and scientific testing to evaluate outcomes and improve management actions. We conducted extensive monitoring of a released population of endangered green and golden bell frogs, Litoria aurea, within a created habitat, as well as complementary surveys of a surrounding wild population. We then compared differences between the created habitat and natural ponds where extant frogs either bred or didn't breed in order to determine factors that contributed to the breeding failure within the created habitat. We evaluated differences of L. aurea abundance, abundance of other fauna, vegetation, water quality, habitat structure, invasive fish, and disease between the three pond types (created habitat, breeding ponds, non-breeding ponds. We discovered that vegetation and invertebrate diversity were low within the created habitat, potentially reducing energy and nutritional resources required for breeding. Also, a greater proportion of frogs in the created habitat were carrying the chytrid fungal pathogen, Batrachochytrium dendrobatidis, compared to the wild populations. In addition to causing the potentially fatal disease, chytridiomycosis, this pathogen has been shown to reduce reproductive functioning in male L. aurea, and subsequently may have reduced reproductive activities in the created habitat. Conspecific attraction, pond hydrology, and aquatic vegetation may also have had some influence on breeding behaviours, whilst the presence of the invasive mosquitofish, Gambusia holbrooki, and heterospecific tadpoles were unlikely to have deterred L. aurea from breeding within the created habitat. Through the use of scientific testing and monitoring, this study is able to make recommendations for future amphibian breed and release programs, and suggests planting a diversity of plant species to attract invertebrates, creating some permanent ponds, connecting habitat with existing populations, trialling artificial mating calls, and following recommendations to reduce the prevalence of disease within the population.

    Full Text Available Abstract Background Little is known about the use of bush medicine and traditional healing among Aboriginal Australians for their treatment of cancer and the meanings attached to it. A qualitative study that explored Aboriginal Australians' perspectives and experiences of cancer and cancer services in Western Australia provided an opportunity to analyse the contemporary meanings attached and use of bush medicine by Aboriginal people with cancer in Western Australia Methods Data collection occurred in Perth, both rural and remote areas and included individual in-depth interviews, observations and field notes. Of the thirty-seven interviews with Aboriginal cancer patients, family members of people who died from cancer and some Aboriginal health care providers, 11 participants whose responses included substantial mention on the issue of bush medicine and traditional healing were selected for the analysis for this paper. Results The study findings have shown that as part of their healing some Aboriginal Australians use traditional medicine for treating their cancer. Such healing processes and medicines were preferred by some because it helped reconnect them with their heritage, land, culture and the spirits of their ancestors, bringing peace of mind during their illness. Spiritual beliefs and holistic health approaches and practices play an important role in the treatment choices for some patients. Conclusions Service providers need to acknowledge and understand the existence of Aboriginal knowledge (epistemology and accept that traditional healing can be an important addition to an Aboriginal person's healing complementing Western medical treatment regimes. Allowing and supporting traditional approaches to treatment reflects a commitment by modern medical services to adopting an Aboriginal-friendly approach that is not only culturally appropriate but assists with the cultural security of the service.

    Sismondo, Sergio

    2013-01-01

    The pharmaceutical industry, in its marketing efforts, often turns to "key opinion leaders" or "KOLs" to disseminate scientific information. Drawing on the author's fieldwork, this article documents and examines the use of KOLs in pharmaceutical companies' marketing efforts. Partly due to the use of KOLs, a small number of companies with well-defined and narrow interests have inordinate influence over how medical knowledge is produced, circulated, and consumed. The issue here, as in many other cases of institutional corruption, is that a few actors have accumulated the power to shape the information on which many others base their decisions. Efforts to address this corruption should focus on correcting large imbalances in the current political economy of medical knowledge. A sequestration of pharmaceutical research and development on one hand from pharmaceutical marketing on the other, though difficult to achieve, would address this and many other problems. © 2013 American Society of Law, Medicine & Ethics, Inc.

  10. Commentary on community-led total sanitation and human rights: should the right to community-wide health be won at the cost of individual rights?

    The Millennium Development Goals (MDGs) set out to halve the proportion of the population without access to basic sanitation between 1990 and 2015. The slow pace of progress has lead to a search for innovative responses, including social motivation approaches. One example of this type of approach is 'Community-led Total Sanitation' (CLTS). CLTS represents a major shift for sanitation projects and programmes in recognising the value of stopping open-defecation across the whole community, even when the individual toilets built are not necessarily wholly hygienic. However, recent publications on CLTS document a number of examples of practices which fail to meet basic ethical criteria and infringe human rights. There is a general theme in the CLTS literature encouraging the use of 'shame' or 'social stigma' as a tool for promoting behaviours. There are reported cases where monetary benefits to which individuals are otherwise entitled or the means to practice a livelihood are withheld to create pressures to conform. At the very extreme end of the scale, the investigation and punishment of violence has reportedly been denied if the crime occurred while defecating in the open, violating rights to a remedy and related access to justice. While social mobilisation in general, and CLTS in particular, have drastically and positively changed the way we think about sanitation, they neither need nor benefit from an association with any infringements of human rights.

  12. I won't let you down... or will I? Core self-evaluations, other-orientation, anticipated guilt and gratitude, and job performance.

    Although core self-evaluations have been linked to higher job performance, research has shown variability in the strength of this relationship. We propose that high core self-evaluations are more likely to increase job performance for other-oriented employees, who tend to anticipate feelings of guilt and gratitude. We tested these hypotheses across 3 field studies using different operationalizations of both performance and other-orientation (prosocial motivation, agreeableness, and duty). In Study 1, prosocial motivation strengthened the association between core self-evaluations and the performance of professional university fundraisers. In Study 2, agreeableness strengthened the association between core self-evaluations and supervisor ratings of initiative among public service employees. In Study 3, duty strengthened the association between core self-evaluations and the objective productivity of call center employees, and this moderating relationship was mediated by feelings of anticipated guilt and gratitude. We discuss implications for theory and research on personality and job performance. Copyright 2009 APA, all rights reserved.

    Productivity is a measure of how efficiently a company uses its resources. The productivity budgeting model (PBM) is one tool that can aid management in the transition from cost-plus, rate-of-return regulation to the market-oriented, cost-control environment of incentive regulation. Most, if not all, utilities use some type of budgeting/forecasting process that provides the blueprint for future company activity. The PBM reveals the growth in total factor productivity (TFP) implied by a budget and, thus, provides a forecast of the company's future efficiency. The PBM can be used to guide resource usage, because it analyzes investment, labor force, and operating decisions from an economic efficiency perspective. In general, the model makes the budgeting process more relevant to the kind of decisions utility management must make for long-term success under incentive regulation. Furthermore, under many incentive regulation. Furthermore, under many incentive regulation plans (such as the FCC's price-cap plan), a company must meet or beat the productivity offset to increase its profitability. With PBM, the company can determine whether its proposed budget is on track and devise a plan to meet any offset. The PBM can also be used to track productivity using financial data from the period in question

    In Vancouver, Canada, there has been a continuous shift in the policing of sex work away from arresting sex workers, which led to the implementation of a policing strategy that explicitly prioritised the safety of sex workers and continued to target sex workers' clients. We conducted semi-structured interviews with 26 cisgender and five transgender women street-based sex workers about their working conditions. Data were analysed thematically and by drawing on concepts of structural stigma and vulnerability. Our results indicated that despite police rhetoric of prioritising the safety of sex workers, participants were denied their citizenship rights for police protection by virtue of their 'risky' occupation and were thus responsiblised for sex work related violence. Our findings further suggest that sex workers' interactions with neighbourhood residents were predominantly shaped by a discourse of sex workers as a 'risky' presence in the urban landscape and police took swift action in removing sex workers in the case of complaints. This study highlights that intersecting regimes of stigmatisation and criminalisation continued to undermine sex workers citizenship rights to police protection and legal recourse and perpetuated labour conditions that render sex workers at increased risk for violence and poor health. © 2016 Foundation for the Sociology of Health & Illness.

    Page, Arnaud

    2016-12-01

    This paper analyses the rise of synthetic nitrogen in Great Britain and its empire, from the First World War to the aftermath of the Second World War. Rather than focus solely on technological innovations and consumption statistics, it seeks to explain how nitrogen was a central element in the expansion of a form of agricultural governance, which needed simplified, stable, and seemingly universal input/output formulae. In the first half of the twentieth century, nitrogen was thus gradually constructed as a global indicator of development, as it was particularly adapted to scientific and political regimes increasingly relying upon abstraction and quantification. Yet, the history of nitrogenous fertilizers in the interwar years also shows that this cannot be reduced to a simple story of triumphant modernity, as their development and globalization was imperfect, unstable, accompanied by resistance and the resilience or emergence of other models. Rather than assuming an all-powerful "state" project, the paper thus seeks to recover the multiplicity of actors, and attempts to account for the rise of nitrogenous fertilizers; not just as the progressive application of a technological breakthrough, but as a difficult process embedded in technological, financial, and military constraints, corporate strategies, political imperatives, and the changing institutional framework of agricultural research.

    2014-12-01

    Full Text Available This article examines the careers of the first two art conservators in North America active outside the north-eastern United States: Charles Muskavitch (1904–2001 and James Roth (1910–1990. Both men trained at the Fogg Art Museum at Harvard University during the 1930s as part of the initial cohort of modern, ‘scientific’ conservators, and remained professionally active into the 1970s. Muskavitch worked initially in Dallas, Texas, and then, from 1939 onward, in Sacramento, California; Roth spent his entire career in Kansas City, Missouri. It is argued that despite their pioneering contributions, they became peripheral to dominant narratives of conservation history because their modest social backgrounds and geographic distance from major institutions led them to be excluded from the powerful networks that developed among their Ivy League-educated contemporaries in the northeast, which continue to shape U.S. conservation up to the present.

    Sexual and gender minority (SGM) adolescents under age 18 are underrepresented in sexual health research. Exclusion of SGM minors from these studies has resulted in a lack of knowledge about the risks and benefits youth experience from sexual health research participation. Institutional Review Boards' (IRB) overprotective stances toward research risks and requirements for guardian consent for SGM research are significant barriers to participation, though few have investigated SGM youth's perspectives on these topics. This study aimed to empirically inform decisions about guardian consent for sexuality survey studies involving SGM youth. A total of 74 SGM youth aged 14-17 completed an online survey of sexual behavior and SGM identity, and a new measure that compared the discomfort of sexual health survey completion to everyday events and exemplars of minimal risk research (e.g., behavioral observation). Youth described survey benefits and drawbacks and perspectives on guardian permission during an online focus group. Participants felt about the same as or more comfortable completing the survey compared to other research procedures, and indicated that direct and indirect participation benefits outweighed concerns about privacy and emotional discomfort. Most would not have participated if guardian permission was required, citing negative parental attitudes about adolescent sexuality and SGM issues and not being "out" about their SGM identity. Findings suggest that sexual health survey studies meet minimal risk criteria, are appropriate for SGM youth, and that recruitment would not be possible without waivers of guardian consent. Decreasing barriers to research participation would dramatically improve our understanding of sexual health among SGM youth.

    2016-03-01

    Do print media significantly impact political attitudes and party identification? To examine this question, we draw on a rare quasi-natural experiment that occurred when The Sun, a right-leaning UK tabloid, shifted its support to the Labour party in 1997 and back to the Conservative party in 2010. We compared changes in party identification and political attitudes among Sun readers with non-readers and other newspaper readerships. We find that The Sun's endorsements were associated with a significant increase in readers' support for Labour in 1997, approximately 525,000 votes, and its switch back was associated with about 550,000 extra votes for the Conservatives in 2010. Although we observed changes in readers' party preference, there was no effect on underlying political preferences. The magnitude of these changes, about 2% of the popular vote, would have been unable to alter the outcome of the 1997 General Election, but may have affected the 2010 Election. Copyright © 2015.

    2016-12-01

    The paper introduces the Baanashada Dumarka, a Somali fertility therapy carried out by a spirit medium, known locally as 'Alaqad. Baanashada is aimed at women whose fertility issues are believed to be caused by spirits. The study also explores a component of the Baanashada, namely, the use of tiire (Rotheca myricoides), or the butterfly bush. Although Rotheca myricoides is known to possess a number of medicinal components as confirmed by studies of modern science, so far, there exist no studies on its potential (or lack of) fertility effects. Hence, the alleged fertility benefits of the butterfly bush need examining. In 2008 a British Somali woman died of herbs placed in her cervix by a traditional healer in Somaliland. This piece of information indicated not only the role of herbal medicine in fertility practices, but also the popularity of traditional reproductive medicine beyond border, class or educational background. Yet, current research into Somali women's health focuses mainly on Female Genital Mutilation (FGM), examined often without the context of wider cultural practices. This paper, however, suggests that rituals, beliefs and material culture play a paramount role in women's practices. For example, as explored elsewhere, the wagar, a wooden and sacred object made of the African olive, is critical for fertility practices. The current paper illuminates further the significance of reproduction practices in Somali society and the potential continuity of traditions associated with the perpetuation of kinship. It concludes that fertility rituals are part of a wider context of interaction with sacred landscapes, objects and archaeological sites, often associated with past legends in the Horn of Africa.

    Rates of Human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs) continue to increase among African-American youth. Adolescents who have a stronger identity in relation to others (relational identity) rather than to themselves (self-identity) may view intimate relationships as imperative to a positive self-concept, which may lead to risky sexual behavior and abuse. Therefore, the present study assessed the associations among a relationship imperative and HIV/STI-related risk factors and behaviors. Participants were 715 African-American adolescent females, aged 15 to 21 years. They completed measures that assessed how important a relationship was to them and HIV-related risk factors and behaviors. Participants also provided vaginal swab specimens for STI testing. Multivariate logistic regression analyses, controlling for covariates, were conducted. Females who endorsed a relationship imperative (29%), compared to those who did not, were more likely to report: unprotected sex, less power in their relationships, perceived inability to refuse sex, anal sex, sex while their partner was high on alcohol/drugs, and partner abuse. Furthermore, participants with less power, recent partner abuse, and a perceived ability to refuse sex were more likely to test STI positive. These results indicate that if African-American adolescent females believe a relationship is imperative, they are more likely to engage in riskier sexual behaviors. Additionally, less perceived power and partner abuse increases their risk for STIs. HIV/STI prevention programs should target males and females and address healthy relationships, sense of self-worth, self-esteem and the gender power imbalance that may persist in the community along with HIV/STI risk.

    2016-02-01

    The role of schools in preventing violence among teenagers has been highlighted, as has the development of youth-led prevention initiatives. This article explores how young people's views on violence influence their perceptions of its preventability, drawing on focus group discussions with 14- to 16-year-olds from six schools across the north of England. Young people view violence as a highly individualized phenomenon, and gender norms play an important role in shaping young people's perceptions of the preventability of violence. The findings presented here suggest that school-based violence prevention must fundamentally address gender norms and expectations to challenge young people's acceptance and tolerance of violence. © The Author(s) 2014.

    Despite the financial crisis and the revisited 2007 prospects, the 2008 edition of the 'World Energy Outlook' (WEO-2008) of the International Energy Agency (OECD/IEA) foresees a regular increase of oil and gas demand. WEO-2008 draws on the experience of another turbulent year in energy markets to provide new energy projections to 2030, region by region and fuel by fuel. It incorporates the latest data and policies. WEO-2008 focuses on two pressing issues facing the energy sector today: - Prospects for oil and gas production: How much oil and gas exists and how much can be produced? Will investment be adequate? Through field-by-field analysis of production trends at 800 of the world's largest oil fields, an assessment of the potential for finding and developing new reserves and a bottom-up analysis of upstream costs and investment, WEO-2008 takes a hard look at future global oil and gas supply. - Post-2012 climate scenarios: What emissions limits might emerge from current international negotiations on climate change? What role could cap-and-trade and sectoral approaches play in moving to a low-carbon energy future? Two different scenarios are assessed, one in which the atmospheric concentration of emissions is stabilised at 550 parts per million (ppm) in CO{sub 2} equivalent terms and the second at the still more ambitious level of 450 ppm. The implications for energy demand, prices, investment, air pollution and energy security are fully spelt out. This ground-breaking analysis will enable policy makers to distill the key choices as they strive to agree in Copenhagen in 2009 on a post-Kyoto climate framework. The good news in this energy outlook is that renewable energies will become in 2020 the second source of power generation.

    On March 23, 2010, President Barack Obama signed the Patient Protection and Affordable Care Act (ACA) into law. As it went through Congress, the legislation faced forceful resistance. Individuals and organizations opposing the ACA circulated propaganda that varied from photographs of fresh graves or coffins with the caption “Result of ObamaCare” to portrayals of President Obama as the Joker from the Batman movies, captioned with the single word “socialism.” The arguments embedded in these images have striking parallels to cartoons circulated by physicians to their patients in earlier fights against national health care. Examining cartoons used in the formative health care reform debates of the 1940s provides a means for tracing the lineage of emotional arguments employed against health care reform. PMID:24328659

    Intervention toolkits are common products of grant-funded research in public health and primary care settings. Toolkits are designed to address the knowledge translation gap by speeding implementation and dissemination of research into practice. However, few studies describe characteristics of effective intervention toolkits and their implementation. Therefore, we conducted this study to explore what clinic and community-based users want in intervention toolkits and to identify the factors that support application in practice. In this qualitative descriptive study we conducted focus groups and interviews with a purposive sample of community health coalition members, public health experts, and primary care professionals between November 2010 and January 2012. The transdisciplinary research team used thematic analysis to identify themes and a cross-case comparative analysis to explore variation by participant role and toolkit experience. Ninety six participants representing primary care (n = 54, 56%) and community settings (n = 42, 44%) participated in 18 sessions (13 focus groups, five key informant interviews). Participants ranged from those naïve through expert in toolkit development; many reported limited application of toolkits in actual practice. Participants wanted toolkits targeted at the right audience and demonstrated to be effective. Well organized toolkits, often with a quick start guide, with tools that were easy to tailor and apply were desired. Irrespective of perceived quality, participants experienced with practice change emphasized that leadership, staff buy-in, and facilitative support was essential for intervention toolkits to be translated into changes in clinic or public -health practice. Given the emphasis on toolkits in supporting implementation and dissemination of research and clinical guidelines, studies are warranted to determine when and how toolkits are used. Funders, policy makers, researchers, and leaders in primary care and public health are encouraged to allocate resources to foster both toolkit development and implementation. Support, through practice facilitation and organizational leadership, are critical for translating knowledge from intervention toolkits into practice.

    2012-01-01

    Full Text Available Multipotent mesenchymal stem cells with extensive self-renewal properties can be easily isolated and rapidly expanded in culture from small volumes of amniotic fluid. These cells, namely, amniotic fluid-stromal cells (AFSCs, can be regarded as an attractive source for tissue engineering purposes, being phenotypically and genetically stable, plus overcoming all the safety and ethical issues related to the use of embryonic/fetal cells. LMP3 is a novel osteoinductive molecule acting upstream to the main osteogenic pathways. This study is aimed at delineating the basic molecular events underlying LMP3-induced osteogenesis, using AFSCs as a cellular model to focus on the molecular features underlying the multipotency/differentiation switch. For this purpose, AFSCs were isolated and characterized in vitro and transfected with a defective adenoviral vector expressing the human LMP3. LMP3 induced the successful osteogenic differentiation of AFSC by inducing the expression of osteogenic markers and osteospecific transcription factors. Moreover, LMP3 induced an early repression of the kruppel-like factor-4, implicated in MSC stemness maintenance. KLF4 repression was released upon LMP3 silencing, indicating that this event could be reasonably considered among the basic molecular events that govern the proliferation/differentiation switch during LMP3-induced osteogenic differentiation of AFSC.

    2000-10-01

    Full Text Available El artículo aborda algunos fenómenos de violencia en ciudades brasileñas, desde un punto de vista comunicacional; la autora logra identificar intersecciones entre ellos, particularmente frente a aspectos de visibilidad, construcción de identidad y sociabilidad que involucran a jóvenes urbanos.Buscando sintetizar reflexiones acerca de ciertas ocurrencias de la violencia –acto social y simbólico- en tal contexto, centra su preocupación en la experimentación de una “cultura do risco” – desafiante, personalista y a veces letal.Propone, además, que la violencia se manifiesta y puede ser percibida bajo un proceso dinámico y dialógico fundado en originales ordenaciones sociales y visuales. Postula, finalmente, que la violencia hoy constituye un poderoso lenguaje, una pedagogía percibida e “incorporada” por diversos sectores juveniles.Este por demás inquietante componente de la comunicación urbana, termina poniendo en evidencia lugares de construcción identitaria a veces tensionados y explosivos, a veces estetizados, poéticos, demarcados por la creciente simbiosis media/sociedad, por la vivencia de los media en cuanto nuevo espacio público y de las ciudades en cuanto peculiares escenarios y focos preferenciales de la visibilidadmediatizada.The article approaches the phenomena of violence in Brazilian cities from a communicational perspective; the author is able to identify intersections between these phenomena, particularly what they have to do with aspects of visibility and construction of identity and sociability as these concepts relate to urban youth.Looking to summarize reflections about certain occurences of violence — a social and symbolic act –- in that context, the author focuses her concern on the experimentation of a “culture of risk,” which is challenging, personalist, and sometimes lethal.In addition, she proposes that violence manifests itself and can be perceived in a dynamic and dialogic process founded on original social and visual orderings. Finally, she postulates that violence today constitutes a powerful language, a pedagogy perceived and “incorporated” by diverse sectors of youth.This very perturbing component of urban communication shows places of construction of identity that are sometimes tense and explosive, sometimes aesthetized, poetic, delimited by the growing media-society symbiosis, by personal experience with the media as a new public space and the cities as peculiar scenarios and preferential focuses of mass media visibility.

    2016-07-01

    Full Text Available This paper presents the complete analysis of Linear Induction Motor (LIM under VVVF. The complete variation of LIM air gap flux under ‘blocked Linor’ condition and starting force is analyzed and presented when LIM is given VVVF supply. The analysis of this data is important in further understanding of the equivalent circuit parameters of LIM and to study the magnetic circuit of LIM. The variation of these parameters is important to know the LIM response at different frequencies. The simulation and application of different control strategies such as vector control thus becomes quite easy to apply and understand motor’s response under such strategy of control.

  4. The Family Smoking Prevention and Tobacco Control Act and the First Amendment: why a substantial interest in protecting public health won't save some new restrictions on tobacco advertising.

    Science.gov (United States)

    Stoll, Elaine

    2010-01-01

    Congress passed the Family Smoking Prevention and Tobacco Control Act in 2009 with the aim of reducing tobacco-related illnesses and deaths by curbing tobacco's appeal to and use by children and adolescents. Legislators considered provisions of the FSPTCA restricting tobacco advertising and labeling key to realizing the law's intended health benefits. But a lawsuit now before the U.S. Court of Appeals for the Sixth Circuit challenges the tobacco marketing restrictions as impermissible restraints on tobacco companies' commercial speech rights under the First Amendment. This article analyzes the constitutionality of each FSPTCA tobacco advertising and labeling restriction in light of U.S. Supreme Court decisions defining the extent of First Amendment protection for commercial speech, prior efforts to restrict tobacco marketing, and the outcomes of legal challenges to some of the prior marketing restrictions. Several of the FSPTCA tobacco advertising and labeling restrictions were drafted with insufficient accommodations for tobacco companies' First Amendment right to convey and consumers' First Amendment right to receive truthful information about lawful tobacco products and are therefore unconstitutional as currently written.

    During World War II, black women migrated largely out of the South to take advantage of the growing defense industries in California. Black women flocked to the shipbuilding industry in Richmond for the great economic opportunities industrial jobs offered. What they found when they arrived and attempted to secure jobs in the shipyards hardly lived up to their dreams and expectations. Black women found themselves faced with dual discrimination due to their race and gender. The shortage of a...

  6. When whole-genome alignments just won't work: kSNP v2 software for alignment-free SNP discovery and phylogenetics of hundreds of microbial genomes.

    Science.gov (United States)

    Gardner, Shea N; Hall, Barry G

    2013-01-01

    Effective use of rapid and inexpensive whole genome sequencing for microbes requires fast, memory efficient bioinformatics tools for sequence comparison. The kSNP v2 software finds single nucleotide polymorphisms (SNPs) in whole genome data. kSNP v2 has numerous improvements over kSNP v1 including SNP gene annotation; better scaling for draft genomes available as assembled contigs or raw, unassembled reads; a tool to identify the optimal value of k; distribution of packages of executables for Linux and Mac OS X for ease of installation and user-friendly use; and a detailed User Guide. SNP discovery is based on k-mer analysis, and requires no multiple sequence alignment or the selection of a single reference genome. Most target sets with hundreds of genomes complete in minutes to hours. SNP phylogenies are built by maximum likelihood, parsimony, and distance, based on all SNPs, only core SNPs, or SNPs present in some intermediate user-specified fraction of targets. The SNP-based trees that result are consistent with known taxonomy. kSNP v2 can handle many gigabases of sequence in a single run, and if one or more annotated genomes are included in the target set, SNPs are annotated with protein coding and other information (UTRs, etc.) from Genbank file(s). We demonstrate application of kSNP v2 on sets of viral and bacterial genomes, and discuss in detail analysis of a set of 68 finished E. coli and Shigella genomes and a set of the same genomes to which have been added 47 assemblies and four "raw read" genomes of H104:H4 strains from the recent European E. coli outbreak that resulted in both bloody diarrhea and hemolytic uremic syndrome (HUS), and caused at least 50 deaths.

    Consumers value word-of-mouth communications in large part because customer reviews are more likely to include negative information about a product or service than are communications originating from the marketer. Despite the fact that negative information is frequently valued by those receiving it, baldly declaring negative information may come with social costs to both communicator and receiver. For this reason, communicators sometimes soften pronouncements of bad news by couching them in d...

  9. 'One sip won't do any harm . . .': temptation among women with inflammatory bowel disease/irritable bowel syndrome to engage in negative dietary behaviours, despite the consequences to their health.

    Science.gov (United States)

    Schneider, Margaret A; Jamieson, Anne; Fletcher, Paula C

    2009-04-01

    The purpose of this research was to explore the dietary lived experiences of university-aged women suffering from inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). This paper will address the decision-making process used by these women when contemplating the consumption of dietary temptations, despite the associated negative consequences. This phenomenological study was guided by heuristic inquiry. A purposive sample of eight women, between the ages of 18 and 23 years, who were living with IBD or IBS were recruited via postings and word-of-mouth. The findings indicate that these women occasionally felt compelled to give into dietary temptations, despite the consequences to their health. The decision-making process they used when considering these negative health behaviours involved three personally controlled parameters. These three parameters included: assessing the cost-benefit relationship before engaging in these behaviours; having a physical and/or psychological reliance on medications to treat resulting symptoms; and through controlling the timing and surroundings in which they indulged in these negative dietary behaviours. The practical implications for health-care professionals treating patients with IBD or IBS are discussed.

Previous studies of AD patients have identified deformations in the brain stem, which may play an important role in the regulation of sleep. The aim of this study was to further investigate the relationship between sleep disturbances and alterations in brain stem morphology in AD.Materials and methods: In 44 patients with AD and 40 healthy elderly controls, sleep disturbances were measured using the Neuropsychiatry Inventory sleep subscale. We employed magnetic resonance imaging-based automated segmentation tools to examine the relationship between sleep disturbances and changes in brain stem morphology.Results: Analyses of the data from AD subjects revealed significant correlations between the Neuropsychiatry Inventory sleep-subscale scores and structural alterations in the left posterior lateral region of the brain stem, as well as normalized brain stem volumes. In addition, significant group differences in posterior brain stem morphology were observed between the AD group and the control group.Conclusion: This study is the first to analyze an association between sleep disturbances and brain stem morphology in AD. In line with previous findings, this study lends support to the possibility that brain stem structural abnormalities might be important neurobiological mechanisms underlying sleep disturbances associated with AD. Further longitudinal research is needed to confirm these findings. Keywords: Alzheimer’s disease, sleep, brain stem, MRI, shape analysis

    Experiments using an electrically biased limiter have been performed on the Texas Experimental Tokamak (TEXT). A small movable limiter is inserted past the main poloidal ring limiter (which is electrically connected to the vacuum vessel) and biased at V Lim with respect to it. The floating potential, plasma potential and shear layer position can be controlled. With vertical strokeV Lim vertical stroke ≥ 50 V the plasma density increases. For V Lim Lim > 0 the results obtained are inconclusive. Variation of V Lim changes the electrostatic turbulence which may explain the observed total flux changes. (orig.)

    A laboratory information management system (LIMS) is central to the informatics infrastructure that underlies biobanking activities. To date, a wide range of commercial and open-source LIMSs are available and the decision to opt for one LIMS over another is often influenced by the needs of the biobank clients and researchers, as well as available financial resources. The Baobab LIMS was developed by customizing the Bika LIMS software ( www.bikalims.org ) to meet the requirements of biobanking best practices. The need to implement biobank standard operation procedures as well as stimulate the use of standards for biobank data representation motivated the implementation of Baobab LIMS, an open-source LIMS for Biobanking. Baobab LIMS comprises modules for biospecimen kit assembly, shipping of biospecimen kits, storage management, analysis requests, reporting, and invoicing. The Baobab LIMS is based on the Plone web-content management framework. All the system requirements for Plone are applicable to Baobab LIMS, including the need for a server with at least 8 GB RAM and 120 GB hard disk space. Baobab LIMS is a server-client-based system, whereby the end user is able to access the system securely through the internet on a standard web browser, thereby eliminating the need for standalone installations on all machines.

    One type of braking system for railway vehicles is the eddy current brake. Because this type of brake has the problem of rail heating, it has not been used for practical applications in Japan. Therefore, we proposed the use of a linear induction motor (LIM) for dynamic braking in eddy current brake systems. The LIM reduces rail heating and uses an inverter for self excitation. In this paper, we estimated the performance of an LIM from experimental results of a fundamental test machine and confirmed that the LIM generates an approximately constant braking force under constant current excitation. At relatively low frequencies, this braking force remains unaffected by frequency changes. The reduction ratio of rail heating is also approximately proportional to the frequency. We also confirmed that dynamic braking resulting in no electrical output can be used for drive control of the LIM. These characteristics are convenient for the realization of the LIM rail brake system.

    Full Text Available The car access time is a key parameter, especially in a huge stereo-garage, where this one should be decreased as much as possible. This paper proposes a novel stereo-garage. Adopting the linear induction motors (LIMs, the system has a simple structure and rapid response capability. In the stereo-garage, several LIMs are installed below the crossbeam on a lifting platform, and several LIMs are fixed on the top of a moving frame. During the operation of LIMs, the moving frame moves forward and backward to reach the required parking place, whereas the crossbeam moves horizontally in order to take or store the vehicle rapidly. All these LIMs are the same and should be designed at a low frequency. The influences of key structure parameters and dynamic performances are investigated, based on FEM. The predicted results are validated by a prototype. Finally, the designed LIMs are successfully applied in two 8-layer stereo-garages.

    Although Linear Inverse Modeling (LIM) provides skillful forecasts of tropical ocean sea surface temperatures, LIM's diagnostic properties are at least as useful as its prognostic properties. In this presentation, we discuss an updated method for using LIM to obtain time series representing stochastic forcing of El Niño and to quantify particular unpredictable contributions to LIM forecast error. Attention is paid to the proper stochastic calculus and to the time scale separation between the stochastic forcing and El Niño's signal. The method yields seldom-considered sources of El Niño's stochastic forcing.

    To explore the understandings of and engagement with e-cigarettes, of young adults from disadvantaged backgrounds, and how these may be impacting upon existing smoking identities. Twenty-two small group and 11 individual qualitative interviews conducted in Central Scotland with 72 16-24 year olds between September 2015 and April 2016. Participants were mostly smokers and ex-smokers from socio-economically disadvantaged backgrounds. While most participants had tried e-cigarettes, they generally held ambivalent views about e-cigarettes and vaping. Two overarching themes were identified which helped understand this. Firstly, e-cigarettes were understood by the participants in relation to their existing smoking identities. Vaping was viewed as less controllable and more addictive than smoking, which did not fit with their self-identity as controlled smokers. Secondly, they felt that vaping could not replace the social and cultural importance that smoking had in their lives. This study suggests that while young adults from disadvantaged areas are trying e-cigarettes for various reasons, vaping is rarely sustained. Through their own experiences of vaping and their observations of others vaping, the participants perceive the behaviour as endangering an existing acceptable and controlled smoking identity. Additionally, e-cigarettes were considered to be a jarring presence in existing social situations were smoking was valued. This study therefore provides insights into how young adults may be rationalising their continued smoking in the face of potentially less harmful alternatives. As new and novel nicotine delivery devices, and due to their similarity to smoking, e-cigarettes have the potential to help smokers in their quit attempts. However, the findings from this study raise questions about whether e-cigarettes are regarded as having this potential by young adult smokers from disadvantaged socio-economic environments where smoking is more commonplace and acceptable. © The Author 2017.

    Although the kidney is a primary organ for vitamin D metabolism, the association between vitamin D and renal cell cancer (RCC) remains unclear. We prospectively evaluated the association between predicted plasma 25-hydroxyvitamin D [25(OH)D] and RCC risk among 72,051 women and 46,380 men in the period from 1986 to 2008. Predicted plasma 25(OH)D scores were computed using validated regression models that included major determinants of vitamin D status (race, ultraviolet B flux, physical activity, body mass index, estimated vitamin D intake, alcohol consumption, and postmenopausal hormone use in women). Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. All statistical tests were two-sided. During 22 years of follow-up, we documented 201 cases of incident RCC in women and 207 cases in men. The multivariable hazard ratios between extreme quintiles of predicted 25(OH)D score were 0.50 (95% CI = 0.32 to 0.80) in women, 0.59 (95% CI = 0.37 to 0.94) in men, and 0.54 (95% CI = 0.39 to 0.75; P trend<.001) in the pooled cohorts. An increment of 10 ng/mL in predicted 25(OH)D score was associated with a 44% lower incidence of RCC (pooled HR = 0.56, 95% CI = 0.42 to 0.74). We found no statistically significant association between vitamin D intake estimated from food-frequency questionnaires and RCC incidence. Higher predicted plasma 25(OH)D levels were associated with a statistically significantly lower risk of RCC in men and women. Our findings need to be confirmed by other prospective studies using valid markers of long-term vitamin D status. Copyright © 2014 Elsevier Inc. All rights reserved.

Such works added to literature thanks to efforts byresearchers give us the opportunity of close acquaintance with religiousworks that are considered as the most significant and the most prolificproducts of Divan Poetry, and of more accurate interpretationsregarding the genre of such works. Apart from works such as aqâid, fiqhand catechism (ilm-i hal in verse, siyer (life of Muhammad in verse,exegeses (tafsir and hadithes in verse that are generally written inpoetic structure for these disciplines, there are also some poetic piecesabout a subdivision or important question of abovementioned Islamicsciences. Faraiz, Hegira of Muhammad, miraj-name, rules of hajj,miracles of Prophet, all in verse, can be mentioned among suchexamples. In the wake of our researches, we found out that thesecatechisms in verse constitute a notable part of our religious literature.Tokatlı İshâk Efendi was an important poet and writer who lived in 17th century. Biographic sources dores not mention him alot. The poetryin rhymed couplets, Nazmu’l-Ulûm, which we are working on shows ushow important poet he is. At his Nazmu’l-Ulûm İshâk Efendi givesinformation about different sciences and wants them to learn. Becauseof these properties Nazmu’l-Ulûm is a written verse advice. Nazmu’l-Ulûm have got strong rhymes. That is possible to say poetry in rhymedcouplets have fascinating expressions rather than bare tellings. Somany telling arts and describtions were given place in that book. Tokatlı İshâk Efendi on yedinci yüzyılda yaşamış önemli bir şâir ve yazardır. Biyografik kaynaklar kendisinden fazla bahsetmez. Ama eserlerinden yola çıktığımızda Tokatlı İshâk Efendi’nin yetenekli bir şâir olduğunu rahatlıkla söyleyebiliriz. İncelediğimiz Nazmu’l-Ulûm adlı mesnevîsinde şâir, çeşitli ilimler hakkında bilgi verdikten sonra bunların öğrenilmesi gerektiğini vurgulamıştır. Mesnevî, arûz vezninin “Mefāīlün Mefāīlün Faūlün” kalıbıyla yazılmış olup 1098/1687 yılında Tokat’ta telif edilmiştir. Mesnevî toplam 422 beyittir. Araştırmalarımız neticesinde yirmi iki nüshasını tespit ettiğimiz mesnevîde çeşitli ilimler hakkında bilgi verildikten sonra bunların öğrenilmesi gereği vurgulanmaktadır. Nazmu’l-Ulûm bu yönüyle manzûm bir nasihatnâme olup öğrenilmesinin öğütlendiği ilimlerin bazıları şunlardır: 1. İlm-i tecvîd, 2. İlm-i Kelâm, 3. İlm-i Fıkıh, 4. İlm-i Tasavvuf ve Ahlâk, 5.

Mesnevîyi oluşturan kelimler dikkate alındığında Arapça ve Farsça kelimelerin çokluğu dikkat çekmektedir. Ama eserin bu özelliği onun akıcılığından bir şey kaybettirmemiştir. Mesnevîde her türlü kafiyeye rastlanmakla birlikte; en çok zengin ve tam kafiyelere yer verilmiş, az sayıda yarım kafiye kullanılmıştır. Mesnevîde, bolca söz sanatlarına ve tasvirlere yer verilmiştir. Gereksiz ifadelerden kaçınılmaya çalışılmıştır. İshâk Efendi arûz veznine ve dile hâkim bir şâirdir. Nazmu’l-Ulûm’da şâirin vezin kusuruna düşmeden dili rahatlıkla kullanması dikkat çekicidir. Bu özellik İshâk Efendi’nin şâirlik gücüne, çok sayıda şiir yazmasına ve yaşadığı dönem olan on yedinci yüzyıla değin Türkçe anlatımdaki gelişmeye de bağlıdır.

Many ADHD patients reportedly have cognitive dysfunction and sleep problems, including longer sleep latency, lower sleep efficiency, and shorter total sleep time. The purpose of this study was to examine neurocognitive functions and nocturnal sleep parameters in patients with ADHD, using a cognitive function test and actigraphy.Methods: Subjects included 37 male patients with ADHD and 32 controls (7–12 years of age. For each participant, we determined intelligence quotient (IQ and administered the Matching Familiar Figures Test (MFFT and 72-hour actigraphy. The relationships between sleep parameters and cognitive functions were assessed.Results: ADHD patients significantly differed from controls in several cognitive functions and sleep variables. In the MFFT, response error rate (P<0.001 and error counts (P=0.003 were significantly increased in ADHD patients compared with control children. MFFT response latency was significantly shorter in ADHD patients than in controls (P<0.001. In addition, sleep latency (P=0.01, wake after sleep onset (WASO (P<0.001, and fragmentation index (P<0.001 were evaluated by actigraphy and found to be significantly increased in patients with ADHD compared with controls. However, no significant differences in total sleep time or sleep efficiency were observed. WASO and response error rates were positively correlated in patients with ADHD (rho =0.52, P=0.012. Furthermore, fragmentation index sleep variables were significantly positively correlated with response error (rho =0.44, P=0.008 and response latency rates (rho =0.4, P=0.018 in the MFFT.

Thus, the aim of this study was to compare the detailed in vivo toxicity of Cu NPs and cupric ions (CuCl2; Cu ions after a single oral dose. We determined the physicochemical characteristics of Cu NPs, including morphology, hydrodynamic size, zeta potential, and dissolution in gastric (pH 1.5, vehicle (pH 6.5, and intestinal (pH 7.8 conditions. We also evaluated the kinetics of Cu following a single equivalent dose (500 mg/kg of Cu NPs and Cu ions. Cu NPs had highest dissolution (84.5% only in gastric conditions when compared with complete dissolution of Cu ions under various physiological milieus. Kinetic analysis revealed that highest Cu levels in blood and tested organs of Cu NP-treated rats were 15%–25% lower than that of Cu ions. Similar to the case of Cu ions, Cu levels in the tested organs (especially liver, kidney, and spleen of Cu NP-treated rats increased significantly when compared with the vehicle control. However, delay in reaching the highest level and biopersistence of Cu were observed in the blood and tested organs of Cu NP-treated rats compared with Cu ions. Extremely high levels of Cu in feces indicated that unabsorbed Cu NPs or absorbed Cu ions were predominantly eliminated through liver/feces. Cu NPs exerted apparent toxicological effects at higher dose levels compared with Cu ions and showed sex-dependent differences in mortality, biochemistry, and

Since CM may be involved in widespread cortico-subcortical networks, identification of the cortical sub-networks specific to the target stimuli may provide further understanding on the underlying mechanisms of CM DBS. Several brain structures have distinguishing brain connections that may be related to the pivotal propagation and subsequent clinical effect of DBS.Methods: To explore core structures and their connections relevant to CM DBS, we applied electroencephalogram (EEG and diffusion tensor imaging (DTI to 10 medically intractable patients – three generalized epilepsy (GE and seven multifocal epilepsy (MFE patients unsuitable for resective surgery. Spatiotemporal activation pattern was mapped from scalp EEG by delivering low-frequency stimuli (5 Hz. Structural connections between the CM and the cortical activation spots were assessed using DTI.Results: We confirmed an average 72% seizure reduction after CM DBS and its clinical efficiency remained consistent during the observation period (mean 21 months. EEG data revealed sequential source propagation from the anterior cingulate, followed by the frontotemporal regions bilaterally. In addition, maximal activation was found in the left cingulate gyrus and the right medial frontal cortex during the right and left CM stimulation, respectively

Methods: Vorinostat and poly(DL-lactide-co-glycolide dissolved in an organic solvent was sprayed onto a GI stent to make a nanofiber-coated stent using an electro-spinning machine. Intact vorinostat and vorinostat released from nanofibers was used to assess anticancer activity in vitro against various CCA cells. The antitumor activity of the vorinostat-eluting nanofiber membrane-coated stent was evaluated using HuCC-T1 bearing mice. Results: A vorinostat-incorporated polymer nanofiber membrane was formed on the surface of the GI stent. Vorinostat was continuously released from the nanofiber membrane over 10 days, and its release rate was higher in cell culture media than in phosphate-buffered saline. Released vorinostat showed similar anticancer activity against various CCA cells in vitro compared to that of vorinostat. Like vorinostat, vorinostat released from nanofibers induced acetylation of histone H4 and inhibited histone deacetylases 1·3·4/5/7 expression in vitro and in vivo. Furthermore, vorinostat nanofibers showed a higher tumor growth inhibition rate in HuCC-T1 bearing mice than vorinostat injections. Conclusion: Vorinostat-eluting nanofiber membranes showed significant antitumor

    According to a high temperature superconducting (HTS) linear induction motor (LIM) designed for rail systems, the influence of electromagnetic parameters and mechanical structure parameters on the electromagnetic horizontal thrust, vertical force of HTS LIM and the maximum vertical magnetic field of HTS windings are analyzed. Through the research on the vertical field of HTS windings, the development regularity of the HTS LIM maximum input current with different stator frequency and different thickness value of the secondary conductive plate is obtained. The theoretical results are of great significance to analyze the stability of HTS LIM. Finally, based on theory analysis, HTS LIM test platform was built and the experiment was carried out with load. The experimental results show that the theoretical analysis is correct and reasonable. (paper)

    The predictability of seasonal anomalies worldwide rests largely on the predictability of tropical sea surface temperature (SST) anomalies. Tropical forecast skill is also a key metric of climate models. We find, however, that despite extensive model development, the tropical SST forecast skill of the operational North American Multi-Model Ensemble (NMME) of eight coupled atmosphere-ocean models remains close both regionally and temporally to that of a vastly simpler linear inverse model (LIM) derived from observed covariances of SST, sea surface height, and wind fields. The LIM clearly captures the essence of the predictable SST dynamics. The NMME and LIM skills also closely track and are only slightly lower than the potential skill estimated using the LIM's forecast signal-to-noise ratios. This suggests that the scope for further skill improvement is small in most regions, except in the western equatorial Pacific where the NMME skill is currently much lower than the LIM skill.

    In T-10 experiments, attempts were made to significantly exceed the Greenwald limit n-bar Gr during high-power (P ab = 750 kW) electron-cyclotron resonance heating (ECRH) and gas puffing. Formally, the density limit (n-bar e ) lim exceeding the Greenwald limit ((n-bar) e ) lim /n-bar Gr = 1.8) was achieved for q L = 8.2. However, as q L decreased, the ratio (n-bar e ) lim /n-bar Gr also decreased, approaching unity at q L ≅ 3. It was suggested that the 'current radius' (i.e., the radius of the magnetic surface enclosing the bulk of the plasma current I p ), rather than the limiter radius, was the parameter governing the value of (n-bar e ) lim . In the ECRH experiments, no substantial degradation of plasma confinement was observed up to n-bar e ∼ 0.9(n-bar e ) lim regardless of the ratio (n(bar sign) e ) lim /n-bar Gr . In different scenarios of the density growth up to (n-bar e ) lim , two types of disruptions related to the density limit were observed

    To observe changes of the partial oxygen pressure in the deep tissues along the Large Intestine Meridian (LIM) during acupuncture stimulation, so as to reveal the characteristics of energy metabolism in the tissues along the LIM. Thirty-one healthy volunteer subjects were enlisted in the present study. Partial oxygen pressure (POP) in the tissues (at a depth of about 1.5 cm) of acupoints Binao (LI 14), Shouwuli (LI 13), Shousanli (LI 10), 2 non-acupoints [the midpoints between Quchi (LI 11) and LI 14, and between Yangxi (LI 5) and LI 11) of the LIM, and 10 non-meridian points, 1.5-2.0 cm lateral and medial to each of the tested points of the LIM was detected before, during and after electroacupuncture (EA) stimulation of Hegu (LI 4) by using a tissue oxygen tension needle-like sensor. In normal condition, the POP values in the deep tissues along the LIM were significantly higher than those of the non-meridian control points on its bilateral sides. During and after EA of Hegu (LI 4), the POP levels decreased significantly in the deep tissues along the LIM in comparison with pre-EA (P 0.05). POP is significantly higher in the deep tissues along the LIM of healthy subjects under normal conditions, which can be downregulated by EA of Hegu (LI 4), suggesting an increase of both the utilization rate of oxygen and energy metabolism after EA.

    Full Text Available The mathematical model of cylindrical linear induction motor (C-LIM fed via frequency converter is presented in the paper. The model was developed in order to analyze numerically the transient states. Problems concerning dynamics of ac-machines especially linear induction motor are presented in [1 – 7]. Development of C-LIM mathematical model is based on circuit method and analogy to rotary induction motor. The analogy between both: (a stator and rotor windings of rotary induction motor and (b winding of primary part of C-LIM (inductor and closed current circuits in external secondary part of C-LIM (race is taken into consideration. The equations of C-LIM mathematical model are presented as matrix together with equations expressing each vector separately. A computational analysis of selected transient states of C-LIM fed via frequency converter is presented in the paper. Two typical examples of C-LIM operation are considered for the analysis: (a starting the motor at various static loads and various synchronous velocities and (b reverse of the motor at the same operation conditions. Results of simulation are presented as transient responses including transient electromagnetic force, transient linear velocity and transient phase current.

    The reducing coal market has been enforcing the coal industry to make exceptional rationalization and restructuring efforts since the end of the eighties. To the competition from crude oil and natural gas has been added the growing pressure from rising wages and rising production cost as the workings get deeper. To improve the competitive position of the coal mines against oil and gas through cost reduction, studies to improve mining system have been carried out. The production of 1995 amounted to 5,719 thousand tons which is less than the last year`s production by 1,719 thousand tons. The investment put for the coal mining mechanization totaled 7,478 million won consisting of 4,176 million won of government subsidy and 3,302 million won of company`s own capital. By increasing mechanization rate from 72 % of the previous year to 75 % and overall O.M.S. from 1.63 ton/man{center_dot}shift to 1.68 ton/man{center_dot} shift the mechanization program got 218.0 billion won of returns compared to the base year 1980 which can be broken down as follows : 1) 89.3 billion won from increase in productivity, 2) 22.0 billion won from increase in calorific value, 3) 5.4 billion won from increase in recovery rate, 4) 101.3 billion won from reduction in accident rate.

    1984-09-01

    The linear induction motor (LIM), as an urban transit drive, can provide good grade-climbing capabilities and propulsion/braking performance that is independent of steel wheel-rail adhesion. In view of its 10-12 mm airgap, the LIM is characterized by a low power factor-efficiency product of order 0.4. A synchronous machine offers high efficiency and controllable power factor. An assessment of the linear homopolar configuration of this machine is presented as an alternative to the LIM. Computer-aided design studies using the finite element technique have been conducted to identify a suitable machine design for urban transit propulsion.

    Singapore is in the process of rolling out a number of national e-health initiatives, including the National Electronic Health Record (NEHR). A critical enabler in the journey towards semantic interoperability is a Logical Information Model (LIM) that harmonises the semantics of the information structure with the terminology. The Singapore LIM uses a combination of international standards, including ISO 13606-1 (a reference model for electronic health record communication), ISO 21090 (healthcare datatypes), and SNOMED CT (healthcare terminology). The LIM is accompanied by a logical design approach, used to generate interoperability artifacts, and incorporates mechanisms for achieving unidirectional and bidirectional semantic interoperability.

  10. Notch-dependent epithelial fold determines boundary formation between developmental fields in the Drosophila antenna.

    Science.gov (United States)

    Ku, Hui-Yu; Sun, Y Henry

    2017-07-01

    Compartment boundary formation plays an important role in development by separating adjacent developmental fields. Drosophila imaginal discs have proven valuable for studying the mechanisms of boundary formation. We studied the boundary separating the proximal A1 segment and the distal segments, defined respectively by Lim1 and Dll expression in the eye-antenna disc. Sharp segregation of the Lim1 and Dll expression domains precedes activation of Notch at the Dll/Lim1 interface. By repressing bantam miRNA and elevating the actin regulator Enable, Notch signaling then induces actomyosin-dependent apical constriction and epithelial fold. Disruption of Notch signaling or the actomyosin network reduces apical constriction and epithelial fold, so that Dll and Lim1 cells become intermingled. Our results demonstrate a new mechanism of boundary formation by actomyosin-dependent tissue folding, which provides a physical barrier to prevent mixing of cells from adjacent developmental fields.

    A model is developed to analyze numerically the electrical properties and the steady-state (limiting) position of the Fermi level (F lim ) in tetrahedral semiconductors irradiated with high-energy particles. It is shown that an irradiated semiconductor represents a highly compensated material, in which F lim is identical to G >/2, where G > is the average energy gap between the conduction band and valence band within the entire Brillouin zone of the crystal. The experimental values of F lim , the calculated values of G >/2, and the data on the electrical properties of irradiated semiconductors are presented. The chemical trends controlling the variation in the quantity F lim in groups of semiconductors with the similar types of chemical bonding are analyzed

    We investigated whether maternal exposure during pregnancy to cow's milk containing endogenous estrogens and insulin like growth factor 1 (IGF-1) and either high or low levels of isoflavones from dietary legumes (HIM and LIM, respectively) affected carcinogen-induced mammary carcinogenesis....... No differences in maternal serum estradiol (P = 0.19) and IGF-1 levels (P = 0.15) at GD 19 or birth weight among the milk and water groups were seen, but estradiol, and IGF-1 levels and birth weight were numerically higher in the LIM than in the HIM group. Puberty onset occurred earlier in the LIM offspring than...... in controls (P = 0.03). Although the high isoflavone content seemed to prevent the effect on circulating estradiol and IGF-1 levels and advanced puberty onset seen in the LIM group, HIM increased DMBA-DNA adducts in the mammary gland and tended to increase mammary tumorigenesis. In contrast, offspring exposed...

    2017-10-01

    This study evaluated the ingestion of sodium bicarbonate (NaHCO 3 ) on postexercise acid-base balance recovery kinetics and subsequent high-intensity cycling time to exhaustion. In a counterbalanced, crossover design, nine healthy and active males (age: 23 ± 2 years, height: 179 ± 5 cm, body mass: 74 ± 9 kg, peak mean minute power (W peak ) 256 ± 45 W, peak oxygen uptake (V̇O 2peak ) 46 ± 8 ml.kg -1 .min -1 ) performed a graded incremental exercise test, two familiarization and two experimental trials. Experimental trials consisted of cycling to volitional exhaustion (T LIM1 ) at 100% W PEAK on two occasions (T LIM1 and T LIM2 ) interspersed by a 90 min passive recovery period. Using a double-blind approach, 30 min into a 90 min recovery period participants ingested either 0.3 g.kg -1 body mass sodium bicarbonate (NaHCO 3 ) or a placebo (PLA) containing 0.1 g.kg -1 body mass sodium chloride (NaCl) mixed with 4 ml.kg -1 tap water and 1 ml.kg -1 orange squash. The mean differences between T LIM2 and T LIM1 was larger for PLA compared with NaHCO 3 (-53 ± 53 vs. -20 ± 48 s; p = .008, d = 0.7, CI =-0.3, 1.6), indicating superior subsequent exercise time to exhaustion following NaHCO 3 . Blood lactate [Bla - ] was similar between treatments post T LIM1 , but greater for NaHCO 3 post T LIM2 and 5 min post T LIM2 . Ingestion of NaHCO 3 induced marked increases (p < .01) in both blood pH (+0.07 ± 0.02, d = 2.6, CI = 1.2, 3.7) and bicarbonate ion concentration [HCO 3 - ] (+6.8 ± 1.6 mmo.l -1 , d = 3.4, CI = 1.8, 4.7) compared with the PLA treatment, before T LIM2 . It is likely both the acceleration of recovery, and the marked increases of acid-base after T LIM1 contributed to greater T LIM2 performance compared with the PLA condition.

    A hybrid standards-based approach has been adopted in Singapore to develop a Logical Information Model (LIM) for healthcare information exchange. The Singapore LIM uses a combination of international standards, including ISO13606-1 (a reference model for electronic health record communication), ISO21090 (healthcare datatypes), SNOMED CT (healthcare terminology) and HL7 v2 (healthcare messaging). This logic-based design approach also incorporates mechanisms for achieving bi-directional semantic interoperability.

  20. The Diversity of the Limnohabitans Genus, an Important Group of Freshwater Bacterioplankton, by Characterization of 35 Isolated Strains

    Bacteria of the genus Limnohabitans, more precisely the R-BT lineage, have a prominent role in freshwater bacterioplankton communities due to their high rates of substrate uptake and growth, growth on algal-derived substrates and high mortality rates from bacterivory. Moreover, due to their generally larger mean cell volume, compared to typical bacterioplankton cells, they contribute over-proportionally to total bacterioplankton biomass. Here we present genetic, morphological and ecophysiological properties of 35 bacterial strains affiliated with the Limnohabitans genus newly isolated from 11 non-acidic European freshwater habitats. The low genetic diversity indicated by the previous studies using the ribosomal SSU gene highly contrasted with the surprisingly rich morphologies and different patterns in substrate utilization of isolated strains. Therefore, the intergenic spacer between 16S and 23S rRNA genes was successfully tested as a fine-scale marker to delineate individual lineages and even genotypes. For further studies, we propose the division of the Limnohabitans genus into five lineages (provisionally named as LimA, LimB, LimC, LimD and LimE) and also additional sublineages within the most diversified lineage LimC. Such a delineation is supported by the morphology of isolated strains which predetermine large differences in their ecology. PMID:23505469

  1. Model-Based Assessment of the CO2 Sequestration Potential of Coastal Ocean Alkalinization

    2017-12-01

    The potential of coastal ocean alkalinization (COA), a carbon dioxide removal (CDR) climate engineering strategy that chemically increases ocean carbon uptake and storage, is investigated with an Earth system model of intermediate complexity. The CDR potential and possible environmental side effects are estimated for various COA deployment scenarios, assuming olivine as the alkalinity source in ice-free coastal waters (about 8.6% of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH. Our results indicate that for a large-enough olivine deployment of small-enough grain sizes (10 µm), atmospheric CO2 could be reduced by more than 800 GtC by the year 2100. However, COA with coarse olivine grains (1000 µm) has little CO2 sequestration potential on this time scale. Ambitious CDR with fine olivine grains would increase coastal aragonite saturation Ω to levels well beyond those that are currently observed. When imposing upper limits for aragonite saturation levels (Ωlim) in the grid boxes subject to COA (Ωlim = 3.4 and 9 chosen as examples), COA still has the potential to reduce atmospheric CO2 by 265 GtC (Ωlim = 3.4) to 790 GtC (Ωlim = 9) and increase ocean carbon storage by 290 Gt (Ωlim = 3.4) to 913 Gt (Ωlim = 9) by year 2100.

    Full Text Available The genus Citrus (Rutaceae includes several species of plants that produce some of the most cultivated fruits in the world, providing an appreciable content of essential oil. In folk medicine, they are used as a cholagogue, antipyretic, anti-inflammatory, sedative, and antitoxic effects. Lemon essential oil has been used since ancient times for its antiseptic, carminative, diuretic, and eupeptic effects. In this study, we investigated the anti-inflammatory activity of Citrus latifolia Tanaka essential oil (CLEO and its main constituent LIM. In the cell viability assay, CLEO and LIM (3, 10, 30, and 90 μg/mL had low cytotoxicity. In zymosan-induced peritonitis, LIM (500 mg/kg decreased the infiltration of peritoneal exudate leukocytes and decreased the number of polymorphonuclear leukocytes. In vitro chemotaxis revealed that CLEO and LIM (1, 3, and 10 µg/mL promoted a significant reduction of neutrophil migration toward fMLP and LTB4. LIM (500 mg/kg also reduced TNF-α levels but did not alter IL-10 levels in the peritoneal exudate. In conclusion, this study showed that LIM isolated from CLEO had potential anti-inflammatory effects, likely by inhibiting proinflammatory mediators present in inflammatory exudate and leukocyte chemotaxis.

    Full Text Available Abstract Background In the post-genome era, most research scientists working in the field of proteomics are confronted with difficulties in management of large volumes of data, which they are required to keep in formats suitable for subsequent data mining. Therefore, a well-developed open source laboratory information management system (LIMS should be available for their proteomics research studies. Results We developed an open source LIMS appropriately customized for 2-D gel electrophoresis-based proteomics workflow. The main features of its design are compactness, flexibility and connectivity to public databases. It supports the handling of data imported from mass spectrometry software and 2-D gel image analysis software. The LIMS is equipped with the same input interface for 2-D gel information as a clickable map on public 2DPAGE databases. The LIMS allows researchers to follow their own experimental procedures by reviewing the illustrations of 2-D gel maps and well layouts on the digestion plates and MS sample plates. Conclusion Our new open source LIMS is now available as a basic model for proteome informatics, and is accessible for further improvement. We hope that many research scientists working in the field of proteomics will evaluate our LIMS and suggest ways in which it can be improved.

    The primary purpose of this study was to investigate the effects of gender difference and caffeine supplementation to maximal voluntary isometric contractions (MVIC) and submaximal voluntary isometric contractions (T(lim)). 10 male (age: 20.10 ± 2.18 years, BMI: 22.23±1.96 kg/m(2)) and 10 female (age: 19.90±0.99 years, BMI: 21.76±2.65 kg/m(2)) elite collegiate athletes were recruited. Subjects ingested caffeine (6 mg/kg) or a placebo in a randomized, double-blind, placebo-control, and counter-balanced fashion. MVIC and T(lim) were measured after supplementations. T(lim) result was calculated based on the time to exhaustion of isometric contraction with 50% MVIC. Fatigue index (FI%) referred to the MVIC tested 20 s after the cessation of T(lim) test, and was indexed by the percentage of MVIC decline. No significant interaction effect was found between the gender factor and the supplementation factor for all dependent variables. Compared to the placebo, caffeine supplementation significantly increased MVIC (5.9%) and T(lim) (15.5%) (pcaffeine supplementation at a 6 mg/kg dosage facilitates performances in MVIC and T(lim). The ergogenic effect of caffeine on muscle power and muscle endurance does not show a gender bias. © Georg Thieme Verlag KG Stuttgart · New York.

    Modern, forensics laboratories need Laboratory Information Management Systems (LIMS) implementations that allow the lab to track evidentiary items through their examination lifecycle and also serve all pertinent laboratory personnel. The research presented here presents LIMS core requirements as viewed by respondents serving in different forensic laboratory capacities as well as different forensic laboratory environments. A product-development methodology was employed to evaluate the relative value of the key features that constitute a LIMS, in order to develop a set of relative values for these features and the specifics of their implementation. In addition to the results of the product development analysis, this paper also provides an extensive review of LIMS and provides an overview of the preparation and planning process for the successful upgrade or implementation of a LIMS. Analysis of the data indicate that the relative value of LIMS components are viewed differently depending upon respondents' job roles (i.e., evidence technicians, scientists, and lab management), as well as by laboratory size. Specifically, the data show that: (1) Evidence technicians place the most value on chain of evidence capabilities and on chain of custody tracking; (2) Scientists generally place greatest value on report writing and generation, and on tracking daughter evidence that develops during their analyses; (3) Lab. Managers place the greatest value on chain of custody, daughter evidence, and not surprisingly, management reporting capabilities; and (4) Lab size affects LIMS preference in that, while all labs place daughter evidence tracking, chain of custody, and management and analyst report generation as their top three priorities, the order of this prioritization is size dependent.
