Sample records for ranunculus adoneus implications

  1. Cytotype segregation on regional and microgeographic scales in snow buttercups (Ranunculus adoneus: Ranunculaceae). (United States)

    Baack, Eric J


    Polyploid speciation is an important source of angiosperm diversity. Insights into the origin and establishment of new polyploid species may be gained by studying the distributions of ancestral and derivative cytotypes at multiple spatial scales. Diploid (2n = 16) and tetraploid (2n = 32) snow buttercups (Ranunculus adoneus: Ranunculaceae) occur in the alpine of the central and southern Rocky Mountains. Root-tip squashes and flow cytometry were used to determine the ploidy of 1618 individuals from 35 populations. Samples from 31 of the 35 sites were entirely of one cytotype, either diploid or tetraploid. Diploid and tetraploid snow buttercups have nonoverlapping regional distributions. Where both cytotypes occur on the same site, the two are spatially segregated despite no apparent change in habitat. Triploid snow buttercups were only found at a diploid/tetraploid contact zone, while two hexaploid plants were found in tetraploid populations. Tetraploid establishment once or twice in the history of the species complex could account for the regional distribution of the two cytotypes. Habitat differentiation between cytotypes or reproductive exclusion of minority cytotypes may explain the observed segregation at both microgeographic and regional scales.

    Bhatti, Muhammad Zeeshan; Ali, Amjad; Ahmad, Ayaz; Saeed, Asma; Malik, Salman Akbar


    Ranunculus arvensis L. (R. arvensis) has long been used to treat a variety of medical conditions such as arthritis, asthma, hay fever, rheumatism, psoriasis, gut diseases and rheumatic pain. Here, we screened R. arvensis for antioxidant activity, phytochemical and high performance liquid chromatography (HPLC) analyses. The chloroform, chloroform:methanol, methanol, methanol:acetone, acetone, methanol:water and water extracts of R. arvensis were examined for DPPH (1, 1-diphenyl-2-picrylhydrazyl) free radical scavenging assay, hydrogen peroxide scavenging assay, phosphomolybdenum assay, reducing power assay, flavonoid content, phenolic content and high performance liquid chromatography analysis. Significant antioxidant activity was displayed by methanol extract (IC 50 34.71 ± 0.02) in DPPH free radical scavenging assay. Total flavonoids and phenolics ranged 0.96-6.0 mg/g of extract calculated as rutin equivalent and 0.48-1.43 mg/g of extract calculated as gallic acid equivalent respectively. Significant value of rutin and caffeic acid was observed via high performance liquid chromatography. These results showed that extracts of R. arvensis exhibited significant antioxidant activities. Moreover, R. arvensis is a rich source of rutin, flavonoids and phenolics.

    The arctic biome is a relatively young ecosystem with ~2300 species of vascular plants. We studied the genus Ranunculus as an example of the origin and evolution of the arctic flora. For this purpose we used molecular phylogenetic and clock analyses based on evaluation of nuclear ITS and chloroplast matK-trnK DNA sequences in 194 taxa of Ranunculus and closely related genera. Taxa occurring in the Arctic arose form seven phylogenetic lineages of Ranunculus and also in the genera Coptidium and Halerpestes. Two clades of Ranunculus are species-rich in the Arctic, i.e., Ranunculus sect. Ranunculus and R. sect. Auricomus (both from R. subg. Ranunculus), but this is due to a number of arctic “microtaxa” morphologically barely separate from R. acris in the former clade and the widely agamospermic species complex of R. auricomus in the latter. Lineages with species adapted to wetlands or aquatic habitats are significant groups represented in the arctic flora (R. subg. Ranunculus sectt. Flammula and Hecatonia/Xanthobatrachium, R. subg. Batrachium, genus Coptidium) but show no clear signs of radiation in the Arctic or the northern boreal zone, except for sectt. Hecatonia/Xanthobatrachium, with R. hyperboreus and R. sceleratus subsp. reptabundus. Astonishingly few of the otherwise numerous lineages of Ranunculus with distributions in the higher mountain systems of Eurasia and North America have acted as “founding sources” for the arctic flora. The only clear example is that of the arctic-alpine R. glacialis and the Beringian R. chamissonis from the lineage of subg. R. sectt. Aconitifolii/Crymodes, although there might be others in sect. Auricomus not recovered in the current molecular data. Lineages that gave rise to arctic taxa diverged from each other from the early Miocene (R. glacialis/R. chamissonis, Coptidium, lineages in Halerpestes) and continued at an even rate throughout the Tertiary. There are no signs that the intense climate changes of the late Pliocene

    The number of completely sequenced plastid genomes available is growing rapidly. This new array of sequences presents new opportunities to perform comparative analyses. In comparative studies, it is most useful to compare across wide phylogenetic spans and, within angiosperms, to include representatives from basally diverging lineages such as the new genomes reported here: Nuphar advena (from a basal-most lineage) and Ranunculus macranthus (from the basal group of eudicots). We report these two new plastid genome sequences and make comparisons (within angiosperms, seed plants, or all photosynthetic lineages) to evaluate features such as the status of ycf15 and ycf68 as protein coding genes, the distribution of simple sequence repeats (SSRs) and longer dispersed repeats (SDR), and patterns of nucleotide composition.

    Full Text Available The five native and naturalised species of Ranunculus L. and Peltocalathos Tamaru (Ranunculaceae: Ranunculeae from southern Africa are reviewed, with full descriptions and nomenclature, taxonomic history, ecological notes, and distribution data. All species are illustrated. Peltocalathos, a monotypic genus based on R. baurii MacOwan, has been overlooked in the regional literature until now. The new name R. dregei J.C.Manning & Goldblatt is proposed as a replacement name for the later homonym R. meyeri Harv., non Lowe. We conclude that the poorly known R. capensis Thunb. represents juvenile forms of the widespread and variable R. multifidus Forssk. and we synonymise the name, along with the three trivial epithets R. pinnatus var. hermannii DC., R. pubescens var. glabrescens Burtt Davy and R. pubescens var. harveyanus Burtt Davy, which have been overlooked in the recent literature. Based on number (mostly < 40 achenes per head and size (mostly 1.2–1.8 mm long of achenes, we conclude that the southern African material of the aquatic species recently re-identified as R. rionii Lagger is more appropriately treated as R. trichophyllus Chaix.

  16. Demographic variation and conservation of the narrow endemic plant Ranunculus weyleri (United States)

    Cursach, Joana; Besnard, Aurélien; Rita, Juan; Fréville, Hélène


    Ranunculus weyleri is a narrow endemic protected plant from Majorca Island. It is known from only five populations located in two mountain areas 48 km apart. Using demographic data collected from 2007 to 2010, we assessed the demographic status of two populations - font des Coloms (FC) and talaia Moreia (TM) - using Integral Projection Models (IPMs). We showed that none of the two populations were declining under a deterministic model. Population FC was stable (λ = 1.026, CI95% = 0.965-1.093), while population TM showed sign of demographic expansion (λ = 1.113, CI95% = 1.032-1.219). Plant survival, flowering probability and the mean number of seedlings per floral peduncle were lower in TM, whereas growth and the number of floral peduncles per reproductive plant were lower in FC. Elasticity analyses showed that management strategies increasing plant survival and growth would be the most efficient to increase λ for both populations. Herbivory pressure by goats has been shown to be high in TM, resulting in high predation rate on floral peduncles. Controlling goat pressure may thus represent a promising management option, provided that we can demonstrate a negative impact of herbivory by goats on survival and growth which are the most critical parts of the life cycle in this species. Meanwhile, initiating a long-term monitoring is of crucial importance to get more insights into the relationships between environmental variation, plant performance and population dynamics.

  17. Uptake of cadmium by the invasive perennial weeds Ranunculus repens and Geranium robertianum under laboratory conditions. (United States)

    O'Keeffe, Juliette; Bendell-Young, L I


    The objective of this study was to compare the accumulation and partitioning of cadmium (Cd) in a fibrous versus a tap root weed, Ranunculus repens and Geranium robertianum respectively. To meet this objective, we compared the accumulation by and the partitioning of Cd in R repens versus G. robertianum grown in soils spiked with 0.015 grams of Cd for a period of three weeks. The rate of Cd uptake was also compared by following the fate of 109Cd within the root, stem and leaf of the two weeds. Prior to Cd exposure, leaf and stem of control R. repens contained significantly greater amounts of Cd as compared to G. robertianum, whereas Cd concentrations in roots of the control plants for the two species were not significantly different (p > 0.05, student's t-test). Post Cd exposure the two species contained similar amounts of Cd in leaf and stem, however, roots of R. repens contained almost two-fold the amounts of Cd as compared to G. robertianum. Comparison of k (h(-1), rate of 109Cd uptake) for stem, leaf and root of the two species indicated that G. robertianum accumulated 109Cd over the first 24-48 h at a faster rate as compared to R. repens. For both species and all three organs, maximum accumulation of 109Cd occurred within the first 24-48 h. Our findings indicate that the fate of Cd within these two species is quite different with the fibrous root of R. repens serving to accumulate and store Cd whereas in G. robertianum, Cd is rapidly taken up and tends to be accumulated within its leaf.

  18. Out of the Alps: colonization of Northern Europe by East Alpine populations of the Glacier Buttercup Ranunculus glacialis L. (Ranunculaceae). (United States)

    Schönswetter, P; Paun, O; Tribsch, A; Niklfeld, H


    Ranunculus glacialis ssp. glacialis is an arctic-alpine plant growing in central and southern European and Scandinavian mountain ranges and the European Arctic. In order to elucidate the taxon's migration history, we applied amplified fragment length polymorphism (AFLP) to populations from the Pyrenees, Tatra mountains and Northern Europe and included data from a previous study on Alpine accessions. Populations from the Alps and the Tatra mountains were genetically highly divergent and harboured many private AFLP fragments, indicating old vicariance. Whereas nearly all Alpine populations of R. glacialis were genetically highly variable, the Tatrean population showed only little variation. Our data suggest that the Pyrenees were colonized more recently than the separation of the Tatra from the Alps. Populations in Northern Europe, by contrast, were similar to those of the Eastern Alps but showed only little genetic variation. They harboured no private AFLP fragments and only a subset of East Alpine ones, and they exhibited no phylogeographical structure. It is very likely therefore that R. glacialis colonized Northern Europe in postglacial times from source populations in the Eastern Alps.

  19. Extra petals in the buttercup (Ranunculus repens) provide a quick method to estimate the age of meadows. (United States)

    Warren, John


    There is a widely used crude method to estimate the age of hedgerows (Hooper's rule) based on species' richness. The aim of this study was to try and establish a similar field method for estimating the age of grasslands based on the accumulation of macro-somatic mutations. A countrywide survey was carried out by the British public to investigate the relationship between grassland age and the number of Ranunculus repens (creeping buttercup) plants with extra petals. In addition the relationship between grassland age and R. repens pollen viability was also investigated. Each plant with flowers with additional petals in a sample of 100 was found to equate to approx. 7 years. A higher significant correlation was observed between pollen viability and population age; however, this is not amenable to providing field estimates. The age of British grasslands can be easily and reliably estimated in the field by counting the number flowers with additional petals in R. repens in meadows up to 200 years old. An attempt to estimate the heritability of extra petals suggests that the phenotype results from the slow accumulation of somatic mutations in a species that primarily reproduces vegetatively.

  20. Historical divergence versus contemporary gene flow: evolutionary history of the calcicole Ranunculus alpestris group (Ranunculaceae) in the European Alps and the Carpathians (United States)

    Paun, O.; Schönswetter, P.; Winkler, M.; Tribsch, A.


    Although many species have similar total distributional ranges, they might be restricted to very different habitats and might have different phylogeographic histories. In the European Alps, our excellent knowledge of the evolutionary history of silicate-dwelling (silicicole) plants is contrasted by a virtual lack of data from limestone-dwelling (calcicole) plants. These two categories exhibit fundamentally different distribution patterns within the Alps and are expected to differ strongly with respect to their glacial history. The calcicole Ranunculus alpestris group comprises three diploid species of alpine habitats. Ranunculus alpestris s. str is distributed over the southern European mountain system, while R. bilobus and R. traunfellneri are Southern Alpine narrow endemics. To explore their phylogenetic relationships and phylogeographic history, we investigated the correlation between information given by nuclear and chloroplast DNA data. Analyses of AFLP fingerprints and matK sequences gave incongruent results, indicative for reticulate evolution. Our data highlight historical episodes of range fragmentation and expansion, occasional long distance dispersal and on-going gene flow as important processes shaping the genetic structure of the group. Genetic divergence, expressed as a rarity index (“frequency-down-weighted marker values”) seems a better indicator of historical processes than patterns of genetic diversity, which rather mirror contemporary processes as connectivity of populations and population sizes. Three phylogeographical subgroups have been found within the R. alpestris group, neither following taxonomy nor geography. Genetic heterogeneity in the Southern Alps contrasts with Northern Alpine uniformity. The Carpathians have been stepwise colonised from the Eastern Alpine lineage resulting in a marked diversity loss in the Southern Carpathians. The main divergence within the group, separating the ancestor of the two endemic species from R

  1. No Genetic Diversity at Molecular Markers and Strong Phenotypic Plasticity in Populations of Ranunculus nodiflorus, an Endangered Plant Species in France (United States)

    Noel, Florence; Machon, Nathalie; Porcher, Emmanuelle


    Background and Aims Although conservation biology has long focused on population dynamics and genetics, phenotypic plasticity is likely to play a significant role in population viability. Here, an investigation is made into the relative contribution of genetic diversity and phenotypic plasticity to the phenotypic variation in natural populations of Ranunculus nodiflorus, a rare annual plant inhabiting temporary puddles in the Fontainebleau forest (Paris region, France) and exhibiting metapopulation dynamics. Methods The genetic diversity and phenotypic plasticity of quantitative traits (morphological and fitness components) were measured in five populations, using a combination of field measurements, common garden experiments and genotyping at microsatellite loci. Key Results It is shown that populations exhibit almost undetectable genetic diversity at molecular markers, and that the variation in quantitative traits observed among populations is due to a high level of phenotypic plasticity. Despite the lack of genetic diversity, the natural population of R. nodiflorus exhibits large population sizes and does not appear threatened by extinction; this may be attributable to large phenotypic plasticity, enabling the production of numerous seeds under a wide range of environmental conditions. Conclusions Efficient conservation of the populations can only be based on habitat management, to favour the maintenance of microenvironmental variation and the resulting strong phenotypic plasticity. In contrast, classical actions aiming to improve genetic diversity are useless in the present case. PMID:17468109

  2. Male meiosis, morphometric analysis and distribution pattern of 2× and 4× cytotypes of Ranunculus hirtellus Royle, 1834 (Ranunculaceae from the cold regions of northwest Himalayas (India

    Puneet Kumar


    Full Text Available In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and morphological features and distribution of 2× and 4× cytotypes of Ranunculus hirtellus Royle, 1834. The majority of the populations scored now from cold regions of the northwest Himalayas showed tetraploid (n=16 meiotic chromosome count and one of the populations studied from the Manimahesh hills existed at diploid level (n=8. The individuals of diploid cytotype exhibited perfectly normal meiotic course resulting in 100% pollen fertility and pollen grains of uniform sizes. On the other hand, the plants of the tetraploid cytotype from all the populations in spite of showing normal bivalent formation and equal distribution to the opposite poles at anaphases showed various meiotic abnormalities. The most prominent among these meiotic abnormalities was the cytomixis which involved inter PMC (pollen mother cell chromatin material transfer at different stages of meiosis-I. The phenomenon of cytomixis induced various meiotic abnormalities which include chromatin stickiness, pycnotic chromatin, laggards and chromatin bridges, out of plate bivalents at metaphase-I, disoriented chromatin material at anaphase/telophase and micronuclei. Consequently, these populations exhibited varying percentages of pollen sterility (24 - 77 % and pollen grains of heterogeneous sizes. Analysis of various morphometric features including the stomata in 2× and 4× cytotypes showed that increase in ploidy level in the species is correlated with gigantism of vegetative and floral characters and the two cytotypes can be distinguished from each other on the basis of morphological characters. The distribution patterns of the 2× and 4× cytotypes now detected and 2×, 3×, 4× cytotypes detected earlier by workers from other regions of the Indian Himalayas have also been discussed.

  4. The partial sequence of RNA 1 of the ophiovirus Ranunculus white mottle virus indicates its relationship to rhabdoviruses and provides candidate primers for an ophiovirus-specific RT-PCR test. (United States)

    Vaira, A M; Accotto, G P; Costantini, A; Milne, R G


    A 4018 nucleotide sequence was obtained for RNA 1 of Ranunculus white mottle virus (RWMV), genus Ophiovirus, representing an incomplete ORF of 1339 aa. Amino acid sequence analysis revealed significant similarities with RNA polymerases of viruses in the family Rhabdoviridae and a conserved domain of 685 aa, corresponding to the RdRp domain of those in the order Mononegavirales. Phylogenetic analysis indicated that the genus Ophiovirus is not related to the genus Tenuivirus or the family Bunyaviridae, with which it has been linked, and probably deserves a special taxonomic position, within a new family. A pair of degenerate primers was designed from a consensus sequence obtained from a relatively conserved region in the RNA 1 of two members of the genus, Citrus psorosis virus (CPsV) and RWMV. The primers, used in RT-PCR experiments, amplified a 136 bp DNA fragment from all the three recognized members of the genus, i.e. CPsV, RWMV and Tulip mild mottle mosaic virus (TMMMV) and from two tentative ophioviruses from lettuce and freesia. The amplified DNAs were sequenced and compared with the corresponding sequences of CPsV and RWMV and phylogenetic relationships were evaluated. Assays using extracts from plants infected by viruses belonging to the genera Tospovirus, Tenuivirus, Rhabdovirus and Varicosavirus indicated that the primers are genus-specific.

  5. The extreme disjunction between Beringia and Europe in Ranunculus glacialis s. l. (Ranunculaceae) does not coincide with the deepest genetic split - a story of the importance of temperate mountain ranges in arctic-alpine phylogeography. (United States)

    Ronikier, M; Schneeweiss, G M; Schönswetter, P


    The arctic-alpine Ranunculus glacialis s. l. is distributed in high-mountain ranges of temperate Europe and in the North, where it displays an extreme disjunction between the North Atlantic Arctic and Beringia. Based on comprehensive sampling and employing plastid and nuclear marker systems, we (i) test whether the European/Beringian disjunction correlates with the main evolutionary diversification, (ii) reconstruct the phylogeographic history in the Arctic and in temperate mountains and (iii) assess the susceptibility of arctic and mountain populations to climate change. Both data sets revealed several well-defined lineages, mostly with a coherent geographic distribution. The deepest evolutionary split did not coincide with the European/Beringian disjunction but occurred within the Alps. The Beringian lineage and North Atlantic Arctic populations, which reached their current distribution via rapid postglacial colonization, show connections to two divergent pools of Central European populations. Thus, immigration into the Arctic probably occurred at least twice. The presence of a rare cpDNA lineage related to Beringia in the Carpathians supports the role of these mountains as a stepping stone between temperate Europe and the non-European Arctic, and as an important area of high-mountain biodiversity. The temperate and arctic ranges presented contrasting phylogeographic histories: a largely static distribution in the former and rapid latitudinal spread in the latter. The persistence of ancient lineages with a strictly regional distribution suggests that the ability of R. glacialis to survive repeated climatic changes within southern mountain ranges is greater than what recently was predicted for alpine plants from climatic envelope modelling. © 2012 Blackwell Publishing Ltd.

  12. Implications of social structure

    DEFF Research Database (Denmark)

    Brask, Josefine Bohr

    Social systems in nature are characterised by heterogeneous social structures. The pattern of social interactions or associations between individuals within populations (i.e. their social network) is typically non-random. Such structuring may have important implications for the expression...... social environment of the individual. In the last two studies, we investigate the role of social structure for cooperation in a classic natural system for behavioural research, the Trinidadian guppy (Poecilia reticulata), by means of computer simulations. Cooperation contradicts evolutionary theory...... and evolution of behaviour, and for individual fitness. In this thesis I investigated implications of social structure for fitness and behaviour, with focus on three main areas: social structure & fitness, social structure & communication, and social structure & cooperation. These areas were investigated...

  13. Epigenetics: ambiguities and implications. (United States)

    Stotz, Karola; Griffiths, Paul


    Everyone has heard of 'epigenetics', but the term means different things to different researchers. Four important contemporary meanings are outlined in this paper. Epigenetics in its various senses has implications for development, heredity, and evolution, and also for medicine. Concerning development, it cements the vision of a reactive genome strongly coupled to its environment. Concerning heredity, both narrowly epigenetic and broader 'exogenetic' systems of inheritance play important roles in the construction of phenotypes. A thoroughly epigenetic model of development and evolution was Waddington's aim when he introduced the term 'epigenetics' in the 1940s, but it has taken the modern development of molecular epigenetics to realize this aim. In the final sections of the paper we briefly outline some further implications of epigenetics for medicine and for the nature/nurture debate.

  14. Advances in fuzzy implication functions

    CERN Document Server

    Beliakov, Gleb; Sola, Humberto; Pradera, Ana


    Fuzzy implication functions are one of the main operations in fuzzy logic. They generalize the classical implication, which takes values in the set {0,1}, to fuzzy logic, where the truth values belong to the unit interval [0,1]. These functions are not only fundamental for fuzzy logic systems, fuzzy control, approximate reasoning and expert systems, but they also play a significant role in mathematical fuzzy logic, in fuzzy mathematical morphology and image processing, in defining fuzzy subsethood measures and in solving fuzzy relational equations. This volume collects 8 research papers on fuzzy implication functions. Three articles focus on the construction methods, on different ways of generating new classes and on the common properties of implications and their dependencies. Two articles discuss implications defined on lattices, in particular implication functions in interval-valued fuzzy set theories. One paper summarizes the sufficient and necessary conditions of solutions for one distributivity equation...

  15. Glycemic variability: Clinical implications

    Directory of Open Access Journals (Sweden)

    Surabhi Venkata Satya Krishna


    Full Text Available Glycemic control and its benefits in preventing microvascular diabetic complications are convincingly proved by various prospective trials. Diabetes control and complications trial (DCCT had reported variable glycated hemoglobin (HbA1C as a cause of increased microvascular complications in conventional glycemic control group versus intensive one. However, in spite of several indirect evidences, its link with cardiovascular events or macrovascular complications is still not proved. Glycemic variability (GV is one more tool to explain relation between hyperglycemia and increased cardiovascular risk in diabetic patients. In fact GV along with fasting blood sugar, postprandial blood sugar, HbA1C, and quality of life has been proposed to form glycemic pentad, which needs to be considered in diabetes management. Postprandial spikes in blood glucose as well as hypoglycemic events, both are blamed for increased cardiovascular events in Type 2 diabetics. GV includes both these events and hence minimizing GV can prevent future cardiovascular events. Modern diabetes management modalities including improved sulfonylureas, glucagon like peptide-1 (GLP-1-based therapy, newer basal insulins, and modern insulin pumps address the issue of GV effectively. This article highlights mechanism, clinical implications, and measures to control GV in clinical practice.

  16. Implications of antisocial parents. (United States)

    Torry, Zachary D; Billick, Stephen B


    Antisocial behavior is a socially maladaptive and harmful trait to possess. This can be especially injurious for a child who is raised by a parent with this personality structure. The pathology of antisocial behavior implies traits such as deceitfulness, irresponsibility, unreliability, and an incapability to feel guilt, remorse, or even love. This is damaging to a child's emotional, cognitive, and social development. Parents with this personality makeup can leave a child traumatized, empty, and incapable of forming meaningful personal relationships. Both genetic and environmental factors influence the development of antisocial behavior. Moreover, the child with a genetic predisposition to antisocial behavior who is raised with a parental style that triggers the genetic liability is at high risk for developing the same personality structure. Antisocial individuals are impulsive, irritable, and often have no concerns over their purported responsibilities. As a parent, this can lead to erratic discipline, neglectful parenting, and can undermine effective care giving. This paper will focus on the implications of parents with antisocial behavior and the impact that this behavior has on attachment as well as on the development of antisocial traits in children.

  1. Astrosociological Implications of Astrobiology (Revisited) (United States)

    Pass, Jim


    Supporters of astrobiology continue to organize the field around formalized associations and organizations under the guise of the so-called ``hard'' sciences (e.g., biology and the related physical/natural sciences). The so-called ``soft'' sciences-including sociology and the other social sciences, the behavioral sciences, and the humanities-remain largely separated from this dynamically growing field. However, as argued in this paper, space exploration involving the search for extraterrestrial life should be viewed as consisting of two interrelated parts (i.e., two sides of the same coin): astrobiology and astrosociology. Together, these two fields broadly combine the two major branches of science as they relate to the relationship between human life and alien life, as appropriate. Moreover, with a formalized system of collaboration, these two complimentary fields would also focus on the implications of their research to human beings as well as their cultures and social structures. By placing the astrosociological implications of astrobiology at a high enough priority, scientists interested in the search for alien life can augment their focus to include the social, cultural, and behavioral implications that were always associated with their work (yet previously overlooked or understated, and too often misunderstood). Recognition of the astrosociological implications expands our perception about alien life by creating a new emphasis on their ramifications to human life on Earth.

  6. Cosmological implications of Heisenberg's principle

    CERN Document Server

    Gonzalo, Julio A


    The aim of this book is to analyze the all important implications of Heisenberg's Uncertainty Principle for a finite universe with very large mass-energy content such as ours. The earlier and main contributors to the formulation of Quantum Mechanics are briefly reviewed regarding the formulation of Heisenberg's Principle. After discussing “indeterminacy” versus ”uncertainty”, the universal constants of physics are reviewed and Planck's units are given. Next, a novel set of units, Heisenberg–Lemaitre units, are defined in terms of the large finite mass of the universe. With the help of Heisenberg's principle, the time evolution of the finite zero-point energy for the universe is investigated quantitatively. Next, taking advantage of the rigorous solutions of Einstein's cosmological equation for a flat, open and mixed universe of finite mass, the most recent and accurate data on the “age” (to) and the expansion rate (Ho) of the universe and their implications are reconsidered.

    Directory of Open Access Journals (Sweden)

    Savić Mile V.


    Full Text Available The article examines the implications of the discourse about postmodernity. Postmodernity is analyzed as a complex discursive figure. Within the discourse about postmodernity three levels are distinguished: the postmodern condition, postmodernism, and reflection of the postmodern condition. Special attention is paid to globalization and the problem of the enforcement of modern projects in East-European societies, particularly Serbia. These societies are termed object-societies, while their modification of modernity is called eastmodernity. The author's answer to the complexity of the postmodern condition is a conception of the politics of subsistence.

  10. John Dewey: implications for schooling. (United States)

    Silva, D


    Propositions, whether great and lasting or insignificant and passing, reside in the "guts of the living." Each age rediscovers its Plato, Dickens, Newton, or Dewey. Each age rewrites history, redefines science, develops its own theoretical perspectives. Propositions are tentative, conditional, or relative. They depend on contemporary priorities, and on a personal space and time context. At any future moment propositions may change, perspectives alter, new choices emerge. John Dewey provided for constructive innovation in schooling and the battles about his suggested criteria continue unabated. The purpose here, however, is only to examine some of Dewey's theoretical propositions and their probable implications (1).

  13. Cosmological Implications of Electroweak Monopole

    Directory of Open Access Journals (Sweden)

    Cho Y. M.


    Full Text Available In this talk we review the basic features of the electroweak monopole, and estimate the remnant electroweak monopole density of the standard model in the present universe. We show that, although the electroweak phase transition is of the first order, the monopole production comes from the thermal fluctuations of the Higgs field after the phase transition, not the vacuum bubble collisions during the phase transition. Moreover, most of the monopoles produced initially are annihilated as soon as created, and this annihilation continues very long time, longer than the muon pair annihilation time. As the result the remnant monopole density at present universe becomes very small, of 10-11 of the critical density, too small to be the dark matter. We discuss the physical implications of our results on the ongoing monopole detection experiments.

  14. Memristor Circuitry via Material Implication (United States)

    Wright, Anna; Gergel-Hackett, Nadine

    Memristors are novel nanoelectronic devices that have advantages over traditional computer circuitry (eg., they are nonvolatile, two-terminal, and low power) and thus have potential circuit applications for both digital logic and memory. In this work, we used a simple memristor model that was designed to replicate the real-world electrical characteristics of previously fabricated and tested memristor devices. This model was developed and constructed with basic circuit elements using a free and widely available circuit simulator, LT Spice. We updated this model to more realistically simulate memristor behavior and then theoretically demonstrated that the model can be used to build memristor-based material implication gates (IMPLY gates). The development of these IMPLY gates is a critical step in the realization of memristor-based digital logic because they can be combined to act in place of any of the basic traditional logic gates (AND, NAND, etc), and thus enable efficient entirely memristor-based computing.

  15. Conflict management: importance and implications. (United States)

    McKibben, Laurie


    Conflict is a consistent and unavoidable issue within healthcare teams. Despite training of nurse leaders and managers around areas of conflict resolution, the problem of staff relations, stress, sickness and retention remain. Conflict arises from issues with interpersonal relationships, change and poor leadership. New members of staff entering an already established healthcare team should be supported and integrated, to encourage mutual role respect between all team members and establish positive working relationships, in order to maximise patient care. This paper explores the concept of conflict, the importance of addressing causes of conflict, effective management, and the relevance of positive approaches to conflict resolution. Good leadership, nurturing positive team dynamics and communication, encourages shared problem solving and acceptance of change. Furthermore mutual respect fosters a more positive working environment for those in healthcare teams. As conflict has direct implications for patients, positive resolution is essential, to promote safe and effective delivery of care, whilst encouraging therapeutic relationships between colleagues and managers.

  16. Cultural variation: considerations and implications. (United States)

    Cohen, D


    Cultural systems vary widely across the world. Partly this is due to different cultures' occupying different ecological and environmental niches. But partly it is due to similar circumstances giving rise to multiple stable equilibriums, each with a distinct cultural form. Using insights and examples from various fields, this article illustrates the way that multiple equilibriums can emerge and the forces that push a culture toward one equilibrium point or another. Considerations of game theory principles, mutual interdependence, historical circumstance, dependence on initial conditions, and crucial choice points are highlighted in discussing the ways humans create and re-create their culture. Cultural traits develop within physical, social, intracultural, and intercultural niches, and implications of this for how culture might be studied and the benefits of combining an "equilibrium" perspective and a "meaning" perspective are discussed.

  2. "Implicate order" and the good life

    DEFF Research Database (Denmark)

    Ravn, Ib

    In an attempt to formulate a coherent view of quantum reality, the theoretical physicist David Bohm has proposed a new concept of order to supplement the mechanistic Cartesian order of traditional physics. The "implicate" order is a subtler and deeper order that emphasizes "unbroken wholeness...... in flowing movement," in contrast to the coarser and more superficial, "explicate" Cartesian order of distinct phenomena. This dissertation attempts to develop a meaning for the idea of implicate order in the human world. First is offerend an account of some evolutionary episodes in terms of implicate...... and explicate order which draws on compatible work in cosmology, embryogenesis, visual perception, brain memory, decision making and phenomenology. Two important characteristics of the implicate order are then identified: in an implicate order, the whole is enfolded (or represented) in each of its parts...

  3. Mining TCGA data using Boolean implications.

    Directory of Open Access Journals (Sweden)

    Subarna Sinha

    Full Text Available Boolean implications (if-then rules provide a conceptually simple, uniform and highly scalable way to find associations between pairs of random variables. In this paper, we propose to use Boolean implications to find relationships between variables of different data types (mutation, copy number alteration, DNA methylation and gene expression from the glioblastoma (GBM and ovarian serous cystadenoma (OV data sets from The Cancer Genome Atlas (TCGA. We find hundreds of thousands of Boolean implications from these data sets. A direct comparison of the relationships found by Boolean implications and those found by commonly used methods for mining associations show that existing methods would miss relationships found by Boolean implications. Furthermore, many relationships exposed by Boolean implications reflect important aspects of cancer biology. Examples of our findings include cis relationships between copy number alteration, DNA methylation and expression of genes, a new hierarchy of mutations and recurrent copy number alterations, loss-of-heterozygosity of well-known tumor suppressors, and the hypermethylation phenotype associated with IDH1 mutations in GBM.

  4. Climatic implications of ice microphysics

    Energy Technology Data Exchange (ETDEWEB)

    Liou, K.N. [Univ. of Utah, Salt Lake City, UT (United States)


    Based on aircraft measurements of mid-latitude cirrus clouds, ice crystal size distribution and ice water content (IWC) are shown to be dependent on temperature. This dependence is also evident from the theoretical consideration of ice crystal growth. Using simple models of the diffusion and accretion growth of ice particles, the computed mean ice crystal size and IWC compare reasonably well with the measured mean values. The temperature dependence of ice crystal size and IWC has important climatic implications in that the temperature field perturbed by external radiative forcings, such as greenhouse warming, can alter the composition of ice crystal clouds. Through radiative transfer, ice microphysics can in turn affect the temperature field. Higher IWC would increase cloud solar albedo and infrared emissivity, while for a given IWC, larger crystals would reduce cloud albedo and emissivity. The competing effects produced by greenhouse temperature perturbations via ice micro-physics and radiation interactions and feedbacks are assessed by a one-dimensional radiative-convective climate model that includes an advanced radiation parameterization program. 3 figs.

  5. Implications of zero economic growth

    Energy Technology Data Exchange (ETDEWEB)

    Thurow, L.C.


    The consequences of a zero economic growth (ZEG) policy are examined to see what limits to growth, some of which already exist, are desirable and what changes in our institutions are required to impose a no-growth policy. Past periods of zero or negative growth have increased unemployment, raised employability standards, and increased income-distribution inequalities with a subsequent lowering of the living standard. Zero population growth would offset this somewhat by freeing the capital now spent on education and career training and using it to raise per capita living standards if a work-sharing and unemployment-payment system were devised. Undesirable social implications would be felt both if a lack of employment opportunities reduced competition and consumption habits or if it led to intensive competition. Advocates of ZEG propose to restrain only those areas using nonrenewable resources and causing pollution of the environment, while expanding the service areas. The service sector (e.g., transportation and utilities) is also polluting and uses nonrenewable resources, however, pointing up their failure to account for indirect consumption. Many undeveloped countries already have ZEG but would not be content for the U.S. to halt growth opportunities. ZEG would be difficult to enforce and would do nothing to promote pollution control.

  6. Venous chest anatomy: clinical implications. (United States)

    Chasen, M H; Charnsangavej, C


    This article provides a practical approach to the clinical implications and importance of understanding the collateral venous anatomy of the thorax. Routine radiography, conventional venography, computed tomography (CT), and magnetic resonance (MR) imaging studies provide correlative anatomic models for the demonstration of how interconnecting collateral vascular networks within the thorax maintain venous stability at all times. Five major systems comprise the collateral venous network of the thorax (Fig. 1). These include the paravertebral, azygos-hemiazygos, internal mammary, lateral thoracic, and anterior jugular venous systems (AJVS). The five systems are presented in the following sequence: (a) a brief introduction to the importance of catheter position and malposition in understanding access to the thoracic venous system, (b) the anatomy of the azygos-hemiazygos systems and their relationship with the paravertebral plexus, (c) the importance of the AJVS, (d) 'loop' concepts interconnecting the internal mammary and azygos-hemiazygos systems by means of the lateral thoracic and intercostal veins, and (e) the interconnecting venous networks on the thoracic side of the thoracoabdominal junction. Certain aspects of the venous anatomy of the thorax will not be discussed in this chapter and include (a) the intra-abdominal anastomoses between the superior and inferior vena cavae (IVC) via the internal mammary, lateral thoracic, and azygos-hemiazygos systems (beyond the scope of this article), (b) potential collateral vessels involving vertebral, parascapular, thyroidal, thymic, and other smaller veins that might anastomose with the major systems, and (c) anatomic variants and pitfalls that may mimic pathologic conditions (space limitations).

  7. Trace elements: implications for nursing. (United States)

    Hayter, J


    Although most were unknown a few years ago, present evidence indicates that at least 25 trace elements have some pertinence to health. Unlike vitamins, they cannot be synthesized. Some trace elements are now considered important only because of their harmful effects but traces of them may be essential. Zinc is especially important during puberty, pregnancy and menopause and is related to protein metabolism. Both fluoride and cadmium accumulate in the body year after year. Cadmium is positively correlated with several chronic diseases, especially hypertension. It is obtained from smoking and drinking soft water. Silicon, generally associated with silicosis, may be necessary for healthy bone and connective tissue. Chromium, believed to be the glucose tolerance factor, is obtained from brewer's yeast, spices, and whole wheat products. Copper deficiency may be implicated in a wide range of cardiovascular and blood related disorders. Either marginal deficiencies or slight excesses of most trace elements are harmful. Nurses should instruct patients to avoid highly refined foods, fad diets, or synthetic and fabricated foods. A well balanced and varied diet is the best safeguard against trace element excesses or deficiencies.

  8. Energy implications of bottled water (United States)

    Gleick, P. H.; Cooley, H. S.


    As bottled water use continues to expand around the world, there is growing interest in the environmental, economical, and social implications of that use, including concerns about waste generation, proper use of groundwater, hydrologic effects on local surface and groundwater, economic costs, and more. A key concern is how much energy is required to produce and use bottled water. This paper estimates the energy footprint required for various phases of bottled water production, transportation, and use. We do not develop a single comprehensive life-cycle energy estimate because of differences among water sources, bottling processes, transportation costs, and other factors, but we quantify key energy inputs necessary for site-specific assessments. We also apply these inputs to three site-specific examples of the energy required from production to the point of use: local bottled water produced and used in Los Angeles, water bottled in the South Pacific and shipped by cargo ship to Los Angeles, and water bottled in France and shipped in various ways to Los Angeles. For water transported short distances, the energy requirements of bottled water are dominated by the energy used to produce the plastic bottles. Long-distance transport, however, can lead to energy costs comparable to, or even larger than, those of producing the bottle. All other energy costs—for processing, bottling, sealing, labeling, and refrigeration—are far smaller than those for the production of the bottle and transportation. These data can be used to generate specific estimates for different sources, treatments, and delivery options.

Routine radiography, conventional venography, computed tomography (CT), and magnetic resonance (MR) imaging studies provide correlative anatomic models for the demonstration of how interconnecting collateral vascular networks within the thorax maintain venous stability at all times. Five major systems comprise the collateral venous network of the thorax ( Fig. 1 ). These include the paravertebral, azygos-hemiazygos, internal mammary, lateral thoracic, and anterior jugular venous systems (AJVS). The five systems are presented in the following sequence: (a) a brief introduction to the importance of catheter position and malposition in understanding access to the thoracic venous system, (b) the anatomy of the azygos-hemiazygos systems and their relationship with the paravertebral plexus, (c) the importance of the AJVS, (d) 'loop' concepts interconnecting the internal mammary and azygos-hemiazygos systems by means of the lateral thoracic and intercostal veins, and (e) the interconnecting venous networks on the thoracic side of the thoracoabdominal junction. Certain aspects of the venous anatomy of the thorax will not be discussed in this chapter and include (a) the intra-abdominal anastomoses between the superior and inferior vena cavae (IVC) via the internal mammary, lateral thoracic, and azygos-hemiazygos systems (beyond the scope of this article), (b) potential collateral vessels involving vertebral, parascapular, thyroidal, thymic, and other smaller veins that might anastomose with the major systems, and (c) anatomic variants and pitfalls that may mimic pathologic conditions (space limitations).

  18. Economic and policy implications of pandemic influenza.

    Energy Technology Data Exchange (ETDEWEB)

    Smith, Braeton J.; Starks, Shirley J.; Loose, Verne W.; Brown, Theresa Jean; Warren, Drake E.; Vargas, Vanessa N.


    Pandemic influenza has become a serious global health concern; in response, governments around the world have allocated increasing funds to containment of public health threats from this disease. Pandemic influenza is also recognized to have serious economic implications, causing illness and absence that reduces worker productivity and economic output and, through mortality, robs nations of their most valuable assets - human resources. This paper reports two studies that investigate both the short- and long-term economic implications of a pandemic flu outbreak. Policy makers can use the growing number of economic impact estimates to decide how much to spend to combat the pandemic influenza outbreaks. Experts recognize that pandemic influenza has serious global economic implications. The illness causes absenteeism, reduced worker productivity, and therefore reduced economic output. This, combined with the associated mortality rate, robs nations of valuable human resources. Policy makers can use economic impact estimates to decide how much to spend to combat the pandemic influenza outbreaks. In this paper economists examine two studies which investigate both the short- and long-term economic implications of a pandemic influenza outbreak. Resulting policy implications are also discussed. The research uses the Regional Economic Modeling, Inc. (REMI) Policy Insight + Model. This model provides a dynamic, regional, North America Industrial Classification System (NAICS) industry-structured framework for forecasting. It is supported by a population dynamics model that is well-adapted to investigating macro-economic implications of pandemic influenza, including possible demand side effects. The studies reported in this paper exercise all of these capabilities.

  20. Implications of the sexual revolution. (United States)

    Dominian, J


    2 sexual revolutions have occurred in the last 30 years: an immense increase in knowledge of sexual matters and the accompanying expansion of providing therapy for sexual disorders; and a radical change in sexual attitudes and behavior. Discussion focuses on the ethical implications of these changes. The standards of sexual morality in this society are derived from the Judeo Christian tradition. In the beginning of Genesis there are 2 passages which are fundamental for the origin and understanding of traditional morality. In these 2 passages sexuality is first linked with establishing a man woman permanent relationship and secondly as the means of giving rise to new life. The origins of the standard Christian mortality about sex was that it was good for procreation and procreation was confined to marriage. All sexual activity before marriage and outside marriage was condemned; fornication and adultery were both wrong. This tradition of confining sex to marriage for the purpose of procreation has continued to the present when it has been widely challenged and contravened. The advent of birth control has had a pronounced effect. For the 1st time sexual intercourse and procreation are totally and effectively separated. As a result sexual activity in previously forbidden situations is now rampant. There exists an extensive preoccupation with sex. Many lavish praise on love making, yet it all depends on what is meant by lovemaking. There are at least 3 ways of understanding lovemaking: solitary sex; transient sex between a couple; and sexual intercourse within marriage. There are single people who extol solitary sex, people who insist that they do not need other people in their life. Masturbation has a place in the life of adolescents and may reassert itself when men and women are separated, but the pleasure of mutual involvement is so much greater that masturbation readily yields to heterosexual activity in the majority of cases and homosexual activity in a small

  1. [New inflammation modulator interleukins . Therapeutic implications]. (United States)

    Lupuşoru, Catălina Elena; Tarţău, Liliana; Ghiciuc, Cristina


    A lot of different leukocyte recruit soluble factors are implicated in both acute and chronic inflammatory processes with a higher expression of the cellular adhesion and chemoattraction molecules. Soluble factors implicated in these processes include: lipid inflammatory metabolites, arachydonic acid derivatives (prostaglandines, leucotrienes, lipoxines, PAF), the three soluble proteases waterfall events/substrates (coagulation, complement, kinines), nitric oxide, as well as cytokines implicated in acute or chronic inflammatory and cellular immune reactions. Recently, new inflammation modulator cytokines were described: IL-20, IL-21, IL-22 and IL-23. The aim of this work was to present some theoretical aspects regarding the biological effects of these new cytokines implicated in inflammation and the pharmacological influence of the processes mediated by them. Particularly IL-20 is implicated in psoriasis pathology. IL-21 and IL-15 are important in NK cells differentiation. IL-22 regulates the IL-4 production from Th2T cells. IL-23 stimulates IFN gamma production and proliferation in PHA blast T cells, as well as in CD45RO (memory) T cells.

  3. Essentializing race: its implications on racial categorization. (United States)

    Chao, Melody Manchi; Hong, Ying-yi; Chiu, Chi-yue


    Racial classification has drawn increasing attention in public discourse; it intertwines with issues related to racialized perceptions. However, few social psychological studies have systematically examined racial categorization processes and their implications for interracial relations. In 5 studies, we investigated the role of racial essentialism in influencing several important psychological aspects of racial categorization. Results linked the belief in racial essentialism to an increased tendency to engage in race-based categorization (Studies 1-3) and greater sensitivity in discerning racial group membership (Studies 4-5). These results are discussed in terms of their implications for understanding and managing interracial relations in the United States.

  7. Theoretical, regulatory and practical implications of logistics

    Directory of Open Access Journals (Sweden)

    Mirosław Chaberek


    Full Text Available Background: The logistics has its practical input in creating economical strategies as well as in creating modern economic environment. Processes of planning, designing and functioning of logistic systems must be based both on the theoretical knowledge covering various areas as well as practical experiences to provide the required support.  To provide logistic services in the rational way, it is necessary to learn the complicated set of implications resulting from three areas covering the theoretical knowledge, practical ones as well as the regulation by the law. Methods: The triad of three concepts: theory, practice and regulation is the main area of consideration in relation to tasks of the logistic support provided by any organization for any production process. The aim of this paper focuses on the necessity of taking into account implications among theory, practice and regulation during the process of analyzing, designing and implementation of systems of the logistic support. The lack of awareness of differences between various implications or ignoring them must lead to irrational behaviors. Results: The implications among theory, practice and legislative regulation of logistics presented differently than usually, broaden the logistic knowledge and at the same time provide the tool of the rationalization of logistic services in all kinds of activities. Conclusions: The correct identification of tasks and functions of the logistics leads to the recognition of its subject and tasks and correct identification of implications occurring among theory, practice and regulation. This knowledge is indispensable in the process of creation of projects of logistic services of each activity, both business and non-business one.

  8. Socioeconomic implications of underdiagnosing teenagers' depression. (United States)

    Burlea, Anamaria; Chiriţă, V; Săcuiu, Irina; Chiriţă, Roxana


    The aim of our research was to demonstrate once again that teenagers' depression still remains way too much underdiagnosed, the last one having important socioeconomic implications. Thus it is absolutely necessary to implement depression screening in psychiatric clinics. The study was carried out in 2 stages, I; a group of 1126 in-patients from "Sf. Maria" Hospital, and II the analysis of the socioeconomic implications of teenagers' depression. Only 19, 11% of the depressive patients had a previous depression diagnosis, the rest of 80, 89% were new cases, recently diagnosed; the depressive teenagers are more exposed to drugs and alcohol abuse, to antisocial behavior, and to poorer results in school. Screening depression implementation would reduce very much the risk of teenagers' depression underdiagnosing.

This report provides the coral reef managers of American Samoa, as well as other coral reef managers in the Pacific region, with some management options to help enhance the capacity of local coral reefs to resist the negative effects of climate change. This report was designed to take advantage of diverse research and monitoring efforts that are ongoing in American Samoa to: analyze and compile the results of multiple research projects that focus on understanding climate-related stressors and their effects on coral reef ecosystem degradation and recovery; and assess implications for coral reef managment of the combined information, including possible response options.

  10. Proof-graphs for Minimal Implicational Logic

    Directory of Open Access Journals (Sweden)

    Marcela Quispe-Cruz


    Full Text Available It is well-known that the size of propositional classical proofs can be huge. Proof theoretical studies discovered exponential gaps between normal or cut free proofs and their respective non-normal proofs. The aim of this work is to study how to reduce the weight of propositional deductions. We present the formalism of proof-graphs for purely implicational logic, which are graphs of a specific shape that are intended to capture the logical structure of a deduction. The advantage of this formalism is that formulas can be shared in the reduced proof. In the present paper we give a precise definition of proof-graphs for the minimal implicational logic, together with a normalization procedure for these proof-graphs. In contrast to standard tree-like formalisms, our normalization does not increase the number of nodes, when applied to the corresponding minimal proof-graph representations.

  11. Pharmacogenomics and Implications for Nursing Practice. (United States)

    Cheek, Dennis J; Bashore, Lisa; Brazeau, Dan Alan


    This article aims to introduce the nurse to pharmacogenomics and its implications for clinical practice with regard to drug therapy. Pharmacogenomics is discussed with regard to the basic tenets, relationships to common health conditions, education and practice resources, and implications for nursing practice. Peer-reviewed literature, websites, and expert professional guidelines were reviewed with relation to pharmacogenomics and nursing practice. The genetic-genomic literature has grown significantly since the completion of the Human Genome Project in 2003. This information is now being translated into practice with regard to the patient's genetic profile and the impact on drug therapy, which is pharmacogenomics. The utilization of the patient genetic-genomic profile is beginning to have an impact on patient drug therapy in clinical practice. Nurses are in the position to make sure, with the increased translation of pharmacogenomics into clinical practice, that adverse drug reactions are avoided and doses are optimized. © 2015 Sigma Theta Tau International.

  12. Therapeutic implications of the modular headache theory. (United States)

    Young, William B; Piovesan, Elcio J


    A theoretical approach to understanding the primary headaches not yet classified by the International Headache Society classification system has been developed by the authors. It is proposed that groups of neurons, called modules, become activated to produce each symptom of a primary headache disorder and these modules are linked together to produce a headache. Headaches develop phenotypic stability through the process of learned stereotypy. This theory explains the huge diversity of headache phenomenology. It has implications for the classification, research and treatment of headache patients. The modular headache theory has therapeutic implications by directing us to focus on treatable modules and avoiding unnecessary treatment for less treatable symptoms. This allows for rational approaches to CNS hyperexcitability and incorporates the temporal patterns of modular activation into the patient's treatment plan.

  13. Cognitive Variables Implicated In Chronic Pain

    Directory of Open Access Journals (Sweden)

    Moretti, Luciana Sofía


    Full Text Available Since the creation of gate control theory, the importance of psychological variables in chronic pain has emerged. Thus, the cognitive variables are emphasized in between behaviors, emotions and social factors for the explanation of chronic pain. Considering the gate control theory, cognitive variables modulate the other two dimensions of the chronic pain experience: the motivational-afective dimension and the sensory-discriminative dimension (Camacho Martel & Anarte Ortiz, 2001; Gatchel, Peng, Peters, Fuchs & Turk, 2007. The aim of this work is to review the main cognitive variables implicated in the chronic pain experience. Moreover, empirical evidence that support the importance of these variables is presented. Furthermore, it is discussed the clinical implications and the importance of this area in the local context.

  14. Growth laws in cancer: implications for radiotherapy. (United States)

    Castorina, P; Deisboeck, T S; Gabriele, P; Guiot, C


    Comparing the conventional Gompertz tumor growth law (GL) with the "Universal" law (UL), which has recently been proposed and applied to cancer, we have investigated the implications of the growth laws for various radiotherapy regimens. According to the GL, the surviving tumor cell fraction could be reduced ad libitum, independent of the initial tumor mass, simply by increasing the number of treatments. In contrast, if tumor growth dynamics follows the Universal scaling law, there is a lower limit of the surviving fraction that cannot be reduced further regardless of the total number of treatments. This finding can explain the so-called tumor size effect and re-emphasizes the importance of early diagnosis because it implies that radiotherapy may be successful provided that the tumor mass at treatment onset is rather small. Taken together with our previous work, the implications of these findings include revisiting standard radiotherapy regimens and treatment protocols overall.

    The current intellectual scene in psychoanalysis is marked by vigorous theoretical controversies about gender. The ideas being debated have important implications for clinical work, which have not been thoroughly explicated or integrated into common practice. These implications include the following: gender can accrue idiosyncratic meanings; gender identity is considered fluid and rigidity of gender identity deemed problematic; gender-related conflicts are typically described as divergent; analysis of superego conflicts related to gender becomes particularly important; and, finally, gender-related biases are seen as inevitable and must be taken into account in the clinical situation. A detailed clinical example illustrates the application of these ideas. While the more dramatic cases related to gender have been more frequent subjects of study, conflicts about gender are everyday occurrences for our patients and deserve further attention.

  16. Implications of intratumour heterogeneity for treatment stratification. (United States)

    Crockford, Andrew; Jamal-Hanjani, Mariam; Hicks, James; Swanton, Charles


    Despite advances in the diagnosis and treatment of cancer, the majority of advanced metastatic solid tumours remain incurable. Differential gene expression, somatic mutational status, tumour-specific genetic signatures and micro-environmental selection pressures within individual tumours have implications for the success of predictive assays to guide therapeutic intervention. In this review we discuss the evidence for genetic and phenotypic heterogeneity and its potential implications for clinical decision making. We highlight areas of research that could be improved in order to better stratify patient treatment. We also discuss the predictive potential of patient-derived models of tumour response, including xenograft and cell line-based systems within the context of intratumour heterogeneity.

  17. Public health implications of altered puberty timing

    DEFF Research Database (Denmark)

    Golub, M.S.; Collman, G.W.; Foster, P.M.


    Changes in puberty timing have implications for the treatment of individual children, for the risk of later adult disease, and for chemical testing and risk assessment for the population. Children with early puberty are at a risk for accelerated skeletal maturation and short adult height, early...... sexual debut, potential sexual abuse, and psychosocial difficulties. Altered puberty timing is also of concern for the development of reproductive tract cancers later in life. For example, an early age of menarche is a risk factor for breast cancer. A low age at male puberty is associated....... Altered timing of puberty also has implications for behavioral disorders. For example, an early maturation is associated with a greater incidence of conduct and behavior disorders during adolescence. Finally, altered puberty timing is considered an adverse effect in reproductive toxicity risk assessment...

  18. Bioavailability: implications for science/cleanup policy

    Energy Technology Data Exchange (ETDEWEB)

    Denit, Jeffery; Planicka, J. Gregory


    This paper examines the role of bioavailability in risk assessment and cleanup decisions. Bioavailability refers to how chemicals ''behave'' and their ''availability'' to interact with living organisms. Bioavailability has significant implications for exposure risks, cleanup goals, and site costs. Risk to human health and the environment is directly tied to the bioavailability of the chemicals of concern.

In order to complement the theoretical framework of the economic implications and the circular influence of health literacy on the economy, an empirical analysis was carried out using S–TOFHLA. The results suggest that the patients’ personal characteristics and the accessibil...

  20. Disturbing Implications of a Cosmological Constant (United States)

    Dyson, Lisa; Kleban, Matthew; Susskind, Leonard


    In this paper we consider the implications of a cosmological constant for the evolution of the universe, under a set of assumptions motivated by the holographic and horizon complementarity principles. We discuss the ``causal patch'' description of spacetime required by this framework, and present some simple examples of cosmologies described this way. We argue that these assumptions inevitably lead to very deep paradoxes, which seem to require major revisions of our usual assumptions.

  3. Physician-Rating Web Sites: Ethical Implications. (United States)

    Samora, Julie Balch; Lifchez, Scott D; Blazar, Philip E


    To understand the ethical and professional implications of physician behavior changes secondary to online physician-rating Web sites (PRWs). The American Society for Surgery of the Hand (ASSH) Ethics and Professionalism Committee surveyed the ASSH membership regarding PRWs. We sent a 14-item questionnaire to 2,664 active ASSH members who practice in both private and academic settings in the United States. We received 312 responses, a 12% response incidence. More than 65% of the respondents had a slightly or highly unfavorable impression of these Web sites. Only 34% of respondents had ever updated or created a profile for PRWs, although 62% had observed inaccuracies in their profile. Almost 90% of respondents had not made any changes in their practice owing to comments or reviews. One-third of respondents had solicited favorable reviews from patients, and 3% of respondents have paid to improve their ratings. PRWs are going to become more prevalent, and more research is needed to fully understand the implications. There are several ethical implications that PRWs pose to practicing physicians. We contend that it is morally unsound to pay for good reviews. The recourse for physicians when an inaccurate and potentially libelous review has been written is unclear. Some physicians have required patients to sign a waiver preventing them from posting negative comments online. We propose the development of a task force to assess the professional, ethical, and legal implications of PRWs, including working with companies to improve accuracy of information, oversight, and feedback opportunities. It is expected that PRWs will play an increasing role in the future; it is unclear whether there will be a uniform reporting system, or whether these online ratings will influence referral patterns and/or quality improvement.

  12. The Nuremberg Code: its history and implications. (United States)

    Kious, B M


    The Nuremberg Code is a foundational document in the ethics of medical research and human experimentation; the principle its authors espoused in 1946 have provided the framework for modern codes that address the same issues, and have received little challenge and only slight modification in decades since. By analyzing the Code's tragic genesis and its normative implications, it is possible to understand some of the essence of modern experimental ethics, as well as certain outstanding controversies that still plague medical science.

    Kliber, J S; Hoa, G H; Douzou, P; Graffe, M; Grunberg-Manago, M


    Potentiometric studies of ribosomal particles 30S, 50S, and 70S, were designed to investigate possible implications of the electrostatic potentials developed by the 16S and 23S rRNA fractions. Release of protons and proton titrations of these ribosomal fractions were examined as a function of Mg2+ and K+ concentrations. The effects of these cations fit the polyelectrolyte theory remarkably well and are discussed accordingly. PMID:12498

  15. [Gut microbiota: Description, role and pathophysiologic implications]. (United States)

    Landman, C; Quévrain, E


    The human gut contains 10(14) bacteria and many other micro-organisms such as Archaea, viruses and fungi. Studying the gut microbiota showed how this entity participates to gut physiology and beyond this to human health, as a real "hidden organ". In this review, we aimed to bring information about gut microbiota, its structure, its roles and its implication in human pathology. After bacterial colonization in infant, intestinal microbial composition is unique for each individual although more than 95% can be assigned to four major phyla. The use of culture independent methods and more recently the development of high throughput sequencing allowed to depict precisely gut microbiota structure and diversity as well as its alteration in diseases. Gut microbiota is implicated in the maturation of the host immune system and in many fundamental metabolic pathways including sugars and proteins fermentation and metabolism of bile acids and xenobiotics. Imbalance of gut microbial populations or dysbiosis has important functional consequences and is implicated in many digestive diseases (inflammatory bowel diseases, colorectal cancer, etc.) but also in obesity and autism. These observations have led to a surge of studies exploring therapeutics which aims to restore gut microbiota equilibrium such as probiotics or fecal microbiota transplantation. But recent research also investigates biological activity of microbial products which could lead to interesting therapeutics leads.

  16. Energy Drinks: Implications for the Breastfeeding Mother. (United States)

    Thorlton, Janet; Ahmed, Azza; Colby, David A


    Breastfeeding women may experience disrupted sleep schedules and be tempted to turn to popular energy drinks to reduce fatigue and enhance alertness, prompting the question: What are the maternal and child health implications for breastfeeding mothers consuming energy drinks? Caffeine and vitamin-rich energy drinks contain a variety of herbal ingredients and vitamins; however, ingredient amounts may not be clearly disclosed on product labels. Interactions between herbal ingredients and caffeine are understudied and not well defined in the literature. Some infants can be sensitive to caffeine and display increased irritability and sleep disturbances when exposed to caffeine from breastmilk. Breastfeeding women who consume energy drinks may be ingesting herbal ingredients that have not undergone scientific evaluation, and if taking prenatal vitamins, may unknowingly exceed the recommended daily intake. Caffeinated products are marketed in newer ways, fueling concerns about health consequences of caffeine exposure. We present implications associated with consumption of caffeine and vitamin-rich energy drinks among breastfeeding women. Product safety, labeling, common ingredients, potential interactions, and clinical implications are discussed. Healthcare providers should encourage breastfeeding women to read product labels for ingredients, carbohydrate content, serving size, and to discourage consumption of energy drinks when breastfeeding and/or taking prenatal vitamins, to avoid potential vitamin toxicity.

  17. Investigating Variations in Gameplay: Cognitive Implications

    Directory of Open Access Journals (Sweden)

    Kamran Sedig


    Full Text Available There is increasing interest in creating computer games for learning, problem solving, and other high-level cognitive activities. When investigating whether gameplay is conducive to such activities, gameplay is often studied as a whole. As a result, cognitive implications can be linked to the game but not to its structural elements. Given that gameplay arises from interaction between the player and the game, it is the structural components of interaction that should be investigated to better understand the design of gameplay. Furthermore, minor variations in the components of interaction can have significant cognitive implications. However, such variation has not been studied yet. Thus, to gain a better understanding of how we can study the effect of interaction on the cognitive aspect of gameplay, we conducted an exploratory investigation of two computer games. These games were isomorphic at a deep level and only had one minor difference in the structure of their interaction. Volunteers played these games and discussed the cognitive processes that emerged. In one game, they primarily engaged in planning, but in the other game they primarily engaged in visualizing. This paper discusses the results of our investigation as well as its implications for the design of computer games.

  18. On the Family of Conditional Embedded Implicational Dependencies

    Directory of Open Access Journals (Sweden)

    Victor Felea


    Full Text Available Certain second-order sentences, called conditional embedded implicational dependencies, about relations in a relational database, are defined and studied. This class of dependencies includes some of previously defined dependencies as special cases. Thus, the family of implicational embedded dependencies introduced and studied by R. Fagin can be included in the family of conditional embedded implicational dependencies. The conditional-functional dependencies defined by P. De Bra and J. Paredaens are special cases of new dependencies. The family of conditional embedded implicational dependencies, also contains the family of conditional implicational dependencies, defined by the author. A characterization of a conditional embedded implicational dependency implied by a given class in this family is given. The existence of Armstrong models for a class of conditional embedded implicational dependencies with a single relational symbol is shown. CR categories: 4.33, 5.21, 5.27, 5.32

  19. Phenomenological implications of very special relativity (United States)

    Nayak, Alekha C.; Jain, Pankaj


    We discuss several phenomenological implications of very special relativity (VSR). It is assumed that there is a small violation of Lorentz invariance, and the true symmetry group of nature is a subgroup called SIM(2). This symmetry group postulates the existence of a fundamental or preferred direction in space-time. We study its implications by using an effective action which violates Lorentz invariance but respects VSR. We find that the problem of finding the masses of fundamental fermions is, in general, intractable in the presence of a VSR term. The problem can be solved only in special cases, which we pursue. We next determine the signal of VSR in a torsion pendulum experiment as well as a clock comparison experiment. We find that VSR predicts a signal which is different from other Lorentz violating theories, and hence a dedicated data analysis is needed in order to impose reliable limits. Assuming that a signal is absent in the data, we determine the limits that can be imposed on the VSR parameters. We also study the implications of VSR in particle decay experiments taking the charged pion and kaon decay as an example. The effective interaction between the charged pion and the final state leptons is related to the fundamental VSR mass terms through a loop calculation. We also predict a shift in the angular dependence of the decay products due to VSR. Specifically, we find that these no longer display azimuthal symmetry with respect to the momentum of the pion. Furthermore, the azimuthal and polar angle distributions show time dependence with a period of a sidereal day. This time dependence provides us with a novel method to test VSR in future experiments.

    Full Text Available Climate change presents a great importance in all sectors of the economy, but the agricultural sector is directly influenced by them. These changes have different causes and effects, but the agriculture is known to be a strategic and dynamic sector, which is considered also difficult and a priority of the economy. The higher crop yields guarantee prosperity, economic and financial growth for many countries in the world. The paper aims is to develop an overview on the implications of climate changes in agriculture over the last few years in Europe.

  1. Adolescent Health Implications of New Age Technology. (United States)

    Jacobson, Cara; Bailin, Alexandra; Milanaik, Ruth; Adesman, Andrew


    This article examines the health implications of new age technology use among adolescents. As Internet prevalence has increased, researchers have found evidence of potential negative health consequences on adolescents. Internet addiction has become a serious issue. Pornography is now easily accessible to youth and studies have related pornography with several negative health effects. Cyberbullying has become a large problem as new age technologies have created a new and easy outlet for adolescents to bully one another. These technologies are related to increased morbidity and mortality, such as suicides due to cyberbullying and motor vehicle deaths due to texting while driving. Copyright © 2016 Elsevier Inc.

  2. Honesty, candour, and transparency: clinical implications. (United States)

    Papanikitas, Andrew


    In advance of a medical conference on the duty of candour for medical ethics educators, this paper discusses the duty of candour as a significant development in the culture of medicine. Those who teach medical ethics need to assess its implications for their own practice. It is also a duty that needs to be critically examined in light of both patients' interests and clinical work environments if it is to be practical and not meaningless rhetoric. Two examples of ways in which that critical examination might take place are outlined.

  4. [Epigenetics in tumorigenesis: advances and clinical implications]. (United States)

    Wang, Xian huo; Zhao, Xiu juan; Qiu, Li hua; Wang, Hua qing; Wang, Xi


    Cancer is a leading cause of death worldwide and the total number of cases globally keeps increasing. For many years, cancer has been thought to be caused by a series of DNA sequence alterations and thus is thought to be a "genetic" disease. However, studies in the last decade, including the large-scale cancer genomics projects, have highlighted the rising importance of epigenetic regulation in cancer. Here, we review recent advances in understanding how chromatin-based epigenetic regulation participates in tumorigenesis and discuss the growing implications of these advances for developing novel strategies to prevent, diagnose, as well as treat cancer.

  5. Psoriasis and comorbid diseases: Implications for management. (United States)

    Takeshita, Junko; Grewal, Sungat; Langan, Sinéad M; Mehta, Nehal N; Ogdie, Alexis; Van Voorhees, Abby S; Gelfand, Joel M


    As summarized in the first article in this continuing medical education series, the currently available epidemiologic data suggest that psoriasis may be a risk factor for cardiometabolic disease. Emerging data also suggest associations between psoriasis and other comorbidities beyond psoriatic arthritis, including chronic kidney disease, inflammatory bowel disease, hepatic disease, certain malignancies, infections, and mood disorders. Recognizing the comorbid disease burden of psoriasis is essential for ensuring comprehensive care of patients with psoriasis. The clinical implications of the comorbid diseases that are associated with psoriasis and recommendations for clinical management are reviewed in this article.

  6. Child sexual abuse: consequences and implications. (United States)

    Hornor, Gail


    Sexual abuse is a problem of epidemic proportions in the United States. Given the sheer numbers of sexually abused children, it is vital for pediatric nurse practitioners to understand both short-term and long-term consequences of sexual abuse. Understanding consequences of sexual abuse can assist the pediatric nurse practitioner in anticipating the physical and mental health needs of patients and also may assist in the identification of sexual abuse victims. Sexual abuse typically does not occur in isolation. Implications for practice will be discussed. Copyright © 2010 National Association of Pediatric Nurse Practitioners. Published by Mosby, Inc.

  7. Gut microbiota: Implications in Parkinson's disease. (United States)

    Parashar, Arun; Udayabanu, Malairaman


    Gut microbiota (GM) can influence various neurological outcomes, like cognition, learning, and memory. Commensal GM modulates brain development and behavior and has been implicated in several neurological disorders like Alzheimer's disease, multiple sclerosis, amyotrophic lateral sclerosis, anxiety, stress and much more. A recent study has shown that Parkinson's disease patients suffer from GM dysbiosis, but whether it is a cause or an effect is yet to be understood. In this review, we try to connect the dots between GM and PD pathology using direct and indirect evidence. Copyright © 2017 Elsevier Ltd. All rights reserved.

  8. Preeclampsia: pathophysiology and implications for care. (United States)

    Townsend, Nancy S; Drummond, Susan B


    Nurses are increasingly encountering pregnant/postpartum women with hypertensive disorders of pregnancy, of which preeclampsia is one of the most common. The Joint Commission published a Sentinel Event Alert in 2010 on prevention of maternal death. This report notes that one of the 5 leading causes of pregnancy-related mortality between 1991 and 1997 was "hypertensive disorder." Preeclampsia presents significant risk to the health of the mother and the fetus. Clearly, nurses must understand the pathophysiology, assessment, management, recurrence risk, and long-term implications of preeclampsia to participate fully in a management plan that promotes safe patient care.

  9. Implications of Fiscal Responsibility on Economic Growth

    Directory of Open Access Journals (Sweden)

    Anca Florentina Gavriluţă (Vatamanu


    Full Text Available Governmental decisions play an important role in the critical periods of the economy and usually in base of the strategy adopted, can make an effective contribution to the budget process while preserving fiscal discipline. This study tests the implications of fiscal responsibility on economic growth with the scope to analyze and find out the major issue of responsible public finances. In base of logistic regression results, the study leads to the conclusion that may be wise to re-evaluate plans to cut net government revenue in future budgets and instead take a more strategic approach to nurturing growth in the EU economy.

    Olshansky, Brian


    The vagus nerve modulates inflammatory responses in various organ systems. Emerging evidence indicates that the vagus can have profound and complex effects on cardiovascular function, remodeling, arrhythmias, and mortality by several mechanisms. In heart failure and during ischemia, an adverse inflammatory response can occur. The vagus nerve may modulate cardiovascular disease and outcomes by affecting inflammatory responses. Here, evidence for and components of the vagus inflammatory reflex are reviewed and evidence for and implications of effects of vagus activation on inflammation in the cardiovascular system are considered.

  15. The Aeromedical Implications of Parkinson's Disease. (United States)

    Jagathesan, Tania; O'Brien, Michael D


    Parkinson's disease is a progressive neurodegenerative disorder which is encountered in the pilot population and has clinical features that can impact on the flying role. This retrospective study reviewed the United Kingdom Civil Aviation Authority (UK CAA) experience of Parkinson's disease. The aeromedical implications of the condition are discussed and the UK CAA policy for the certificatory assessment of pilots with Parkinson's disease is described. A search of the UK CAA medical records database from 1990 to 2015 identified 34 pilots with a diagnosis of Parkinson's disease. Data was extracted for the class of medical certificate, time from first symptoms to diagnosis, age at diagnosis, the time from diagnosis to loss of certification and the reasons for loss of certification. Of 15 professional (Class 1) and 19 private (Class 2) pilots, the mean time from onset of symptoms to diagnosis was 36 and 19 mo, respectively. The mean ages at diagnosis were 55 and 59 yr, respectively. The mean interval from diagnosis to loss of certification was 21 (0-93) and 37 (0-84) mo, respectively. The reasons for loss of certification are considered. In the UK, pilots diagnosed with Parkinson's disease may be granted medical certification depending on their functional ability and the side effect profile of medication. The aeromedical implications of Parkinson's disease and the UK CAA policy for the certification of pilots with Parkinson's disease are discussed.

  16. Social and ethical implications of BRCA testing. (United States)

    Surbone, A


    Oncologists are asked with increasing frequency to counsel their patients with respect to the medical, psychological and social repercussions of genetic testing for cancer susceptibility that may have been prescribed by physicians or carried out through direct-to-consumer tests. This article critically reviews the main ethical and social implications of BRCA testing, focusing on genetic responsibility and genetic discrimination. Genetic responsibility toward oneself and others is a highly debated implication of genetic testing for cancer predisposition that requires broad considerations of the boundaries between individual and community rights and a reappraisal of the notion of autonomy as relational. Physicians' duty to warn 'at risk' relatives can be an ethical quandary, yet confidentiality is key to the patient-doctor relationship. Mutation carriers may be subject to different forms and degrees of genetic discrimination and many individuals at risk have forgone BRCA testing to avoid potential discrimination. The scientific and medical community, together with patients and the public, has actively engaged against genetic discrimination. The legislation in many countries now protects against genetic discrimination by insurance companies and employers. Legal and regulatory issues are not the final answer to discrimination and profound cultural changes are required to create understanding and acceptance of all differences.

  17. Public health implications of altered puberty timing. (United States)

    Golub, Mari S; Collman, Gwen W; Foster, Paul M D; Kimmel, Carole A; Rajpert-De Meyts, Ewa; Reiter, Edward O; Sharpe, Richard M; Skakkebaek, Niels E; Toppari, Jorma


    Changes in puberty timing have implications for the treatment of individual children, for the risk of later adult disease, and for chemical testing and risk assessment for the population. Children with early puberty are at a risk for accelerated skeletal maturation and short adult height, early sexual debut, potential sexual abuse, and psychosocial difficulties. Altered puberty timing is also of concern for the development of reproductive tract cancers later in life. For example, an early age of menarche is a risk factor for breast cancer. A low age at male puberty is associated with an increased risk for testicular cancer according to several, but not all, epidemiologic studies. Girls and, possibly, boys who exhibit premature adrenarche are at a higher risk for developing features of metabolic syndrome, including obesity, type 2 diabetes, and cardiovascular disease later in adulthood. Altered timing of puberty also has implications for behavioral disorders. For example, an early maturation is associated with a greater incidence of conduct and behavior disorders during adolescence. Finally, altered puberty timing is considered an adverse effect in reproductive toxicity risk assessment for chemicals. Recent US legislation has mandated improved chemical testing approaches for protecting children's health and screening for endocrine-disrupting agents, which has led to changes in the US Environmental Protection Agency's risk assessment and toxicity testing guidelines to include puberty-related assessments and to the validation of pubertal male and female rat assays for endocrine screening.

  18. Forensic implications: adolescent sexting and cyberbullying. (United States)

    Korenis, Panagiota; Billick, Stephen Bates


    Adolescence is marked by establishing a sense of identity, core values, a sense of one's relationship to the outside world and heightened peer relationships. In addition, there is also risk taking, impulsivity, self exploration and dramatic increase in sexuality. The dramatic increase in the use of cell phones and the Internet has additional social implications of sexting and cyberbullying. Sexting refers to the practice of sending sexually explicit material including language or images to another person's cell phone. Cyberbullying refers to the use of this technology to socially exclude, threaten, insult or shame another person. Studies of cell phone use in the 21st century report well over 50% of adolescents use them and that text messaging is the communication mode of choice. Studies also show a significant percentage of adolescents send and receive sex messaging, both text and images. This paper will review this expanding literature. Various motivations for sexting will also be reviewed. This new technology presents many dangers for adolescents. The legal implications are extensive and psychiatrists may play an important role in evaluation of some of these adolescents in the legal context. This paper will also make suggestions on future remedies and preventative actions.

  19. Clinical implications of angiogenesis in cancers

    Directory of Open Access Journals (Sweden)

    Full Text Available Roberta WC Pang1, Ronnie TP Poon2 Departments of 1Medicine and 2Surgery, The University of Hong Kong, Pokfulam, Hong Kong, ChinaAbstract: Angiogenesis plays an important role in the growth and progression of cancer. The regulation of tumor angiogenesis depends on a net balance of angiogenic factors and antiangiogenic factors, which are secreted by both tumor cells and host-infiltrating cells. Numerous studies have indicated that assessment of angiogenic activity by either microvessel density or expression of angiogenic factors in cancer can provide prognostic information independent of conventional clinicopathological factors such as tumor staging. Some studies also suggested that assessment of tumor angiogenesis may predict cancer response to chemotherapy or radiotherapy. However, the most important clinical implication of tumor angiogenesis is the development of a novel strategy of anticancer therapy targeting tumor vessels instead of cancer cells. Antiangiogenic therapy aims to inhibit the growth of tumor, and current evidence suggests that it works best in combination with conventional cytotoxic chemotherapy. Recently, a monoclonal antibody against vascular endothelial growth factor, which is one of the most potent angiogenic factors, has been approved for clinical use in colorectal cancer patients after a clinical trial confirmed that combining the antibody with standard chemotherapy regimen could prolong patient survival. The clinical implications of angiogenesis in cancer are reviewed in this article.Keywords: angiogenesis, antiangiogenic therapy, cancer, prognosis

  20. Implication of Ceramide Kinase in Adipogenesis

    Directory of Open Access Journals (Sweden)

    Marta Ordoñez


    Full Text Available Ceramide kinase (CerK plays a critical role in the regulation of cell growth and survival and has been implicated in proinflammatory responses. In this work, we demonstrate that CerK regulates adipocyte differentiation, a process associated with obesity, which causes chronic low-grade inflammation. CerK was upregulated during differentiation of 3T3-L1 preadipocytes into mature adipocytes. Noteworthy, knockdown of CerK using specific siRNA to silence the gene encoding this kinase resulted in substantial decrease of lipid droplet formation and potent depletion in the content of triacylglycerols in the adipocytes. Additionally, CerK knockdown caused blockade of leptin secretion, an adipokine that is crucial for regulation of energy balance in the organism and that is increased in the obese state. Moreover, CerK gene silencing decreased the expression of peroxisome proliferator-activated receptor gamma (PPARγ, which is considered the master regulator of adipogenesis. It can be concluded that CerK is a novel regulator of adipogenesis, an action that may have potential implications in the development of obesity, and that targeting this kinase may be beneficial for treatment of obesity-associated diseases.

  2. [Mental Imagery: Neurophysiology and Implications in Psychiatry]. (United States)

    Martínez, Nathalie Tamayo


    To provide an explanation about what mental imagery is and some implications in psychiatry. This article is a narrative literature review. There are many terms in which imagery representations are described in different fields of research. They are defined as perceptions in the absence of an external stimulus, and can be created in any sensory modality. Their neurophysiological substrate is almost the same as the one activated during sensory perception. There is no unified theory about its function, but it is possibly the way that our brain uses and manipulates the information to respond to the environment. Mental imagery is an everyday phenomenon, and when it occurs in specific patterns it can be a sign of mental disorders. Copyright © 2014 Asociación Colombiana de Psiquiatría.

  3. Clinical Implications of Sarcopenic Obesity in Cancer. (United States)

    Carneiro, Isabella P; Mazurak, Vera C; Prado, Carla M


    Sarcopenia has been associated with several negative clinical outcomes in cancer. However, the consequences of sarcopenic obesity, a condition of combined sarcopenia and obesity burden, have been less extensively investigated. The aim of this paper was to review the current evidence on the prevalence and clinical implications of sarcopenic obesity in cancer. A total of 14 studies linking sarcopenic obesity to a clinical outcome in cancer were included. There is considerable inconsistency in methods used to evaluate body composition as well as in the criteria used to define sarcopenic obesity, which limits comparison among studies. Therefore, the prevalence of sarcopenic obesity varied substantially: between 1 and 29 % in studies including individuals from all body mass index categories and between 15 and 36 % for those including obese individuals only. Negative clinical outcomes reported to be associated with sarcopenic obesity included higher risk of dose-limiting toxicity, surgical complications, physical disability, and shorter survival.

  4. Implications of the Human Genome Project

    Energy Technology Data Exchange (ETDEWEB)

    Kitcher, P.


    The Human Genome Project (HGP), launched in 1991, aims to map and sequence the human genome by 2006. During the fifteen-year life of the project, it is projected that $3 billion in federal funds will be allocated to it. The ultimate aims of spending this money are to analyze the structure of human DNA, to identify all human genes, to recognize the functions of those genes, and to prepare for the biology and medicine of the twenty-first century. The following summary examines some of the implications of the program, concentrating on its scientific import and on the ethical and social problems that it raises. Its aim is to expose principles that might be used in applying the information which the HGP will generate. There is no attempt here to translate the principles into detailed proposals for legislation. Arguments and discussion can be found in the full report, but, like this summary, that report does not contain any legislative proposals.

    Magali Humeau


    Full Text Available Ce texte propose de rapprocher les autobiographies des écrits de recherche scientifique. Si notre approche n'exclut pas le point de vue sociologique avec en particulier la recherche action, il se veut resserré ici sur l'approche bio-cognitive du sujet-chercheur avec le processus d'autoréférentiation, renvoyant à une épistémologie qui prend en compte et assume l'incomplétude propre à la connaissance. Toute production de savoir, y compris dans le cadre de la recherche scientifique, est ainsi conçue comme un jeu d'implication entre le sujet et son objet, mettant en œuvre nécessairement, mais pas toujours avec conscience, la référence à soi-même, processus permis dans le cadre du discours autobiographique.

  6. Regulated necrosis and its implications in toxicology. (United States)

    Aki, Toshihiko; Funakoshi, Takeshi; Uemura, Koichi


    Recent research developments have revealed that caspase-dependent apoptosis is not the sole form of regulated cell death. Caspase-independent, but genetically regulated, forms of cell death include pyroptosis, necroptosis, parthanatos, and the recently discovered ferroptosis and autosis. Importantly, regulated necrosis can be modulated by small molecule inhibitors/activators, confirming the cell autonomous mechanism of these forms of cell death. The success of small molecule-mediated manipulation of regulated necrosis has produced great changes in the field of cell death research, and has also brought about significant changes in the fields of pharmacology as well as toxicology. In this review, we intend to summarize the modes of regulated cell death other than apoptosis, and discuss their implications in toxicology. Copyright © 2015 Elsevier Ireland Ltd.

  7. Income inequality: Implications and relevant economic policies

    Directory of Open Access Journals (Sweden)

    Arestis Philip


    Full Text Available The aim of this contribution is to discuss closely the implications of income inequality and the economic policies to tackle it, especially so in view of inequality being one of the main causes of the 2007/2008 international financial crisis and the “great recession” that subsequently emerged. Wealth inequality is also important in this respect, but the focus is on income inequality. Ever since the financial crisis and the subsequent “great recession”, inequality of income, and wealth, has increased and the demand for economic policy initiatives to produce a more equal distribution of income and wealth has become more urgent. Such reduction would help to increase the level of economic activity as has been demonstrated again more recently. A number of economic policy initiatives for this purpose will be the focus of this contribution.

  9. Prescription drug abuse: problem, policies, and implications. (United States)

    Phillips, Janice


    This article provides an overview on prescription drug abuse and highlights a number of related legislative bills introduced during the 112th Congress in response to this growing epidemic. Prescription drug abuse has emerged as the nation's fastest growing drug problem. Although prescription drugs have been used effectively and appropriately for decades, deaths from prescription pain medicine in particular have reached epidemic proportions. Bills related to prescription drug abuse introduced during the 112th Congress focus on strengthening provider and consumer education, tracking and monitoring prescription drug abuse, improving data collection on drug overdose fatalities, combating fraud and abuse in Medicare and Medicaid programs, reclassifying drugs to make them more difficult to prescribe and obtain, and enforcing stricter penalties for individuals who operate scam pain clinics and sell pain pills illegitimately. This article underscores the importance of a multifaceted approach to combating prescription drug abuse and concludes with implications for nursing. Copyright © 2013. Published by Mosby, Inc.

  10. Pharmacologic Implications of Marijuana Use During Pregnancy. (United States)

    Fantasia, Heidi Collins

    Marijuana is the most commonly used recreational drug in the United States, including among women of childbearing age and women who are pregnant. Changing legal statutes that allow for the use of medical marijuana and the decriminalization of marijuana for personal use reflect more permissive societal views on the use of this drug. Active compounds in marijuana cross the placenta rapidly and are excreted in breast milk. Results of studies of the effects of marijuana on a developing fetus and neonate are conflicting, but researchers have identified chronic marijuana exposure as a risk factor for preterm birth and small-for-gestational-age infants. This article reviews the pharmacology of marijuana and discusses implications for nurses who work with women of childbearing age. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

  11. Life Sciences Implications of Lunar Surface Operations (United States)

    Chappell, Steven P.; Norcross, Jason R.; Abercromby, Andrew F.; Gernhardt, Michael L.


    The purpose of this report is to document preliminary, predicted, life sciences implications of expected operational concepts for lunar surface extravehicular activity (EVA). Algorithms developed through simulation and testing in lunar analog environments were used to predict crew metabolic rates and ground reaction forces experienced during lunar EVA. Subsequently, the total metabolic energy consumption, the daily bone load stimulus, total oxygen needed, and other variables were calculated and provided to Human Research Program and Exploration Systems Mission Directorate stakeholders. To provide context to the modeling, the report includes an overview of some scenarios that have been considered. Concise descriptions of the analog testing and development of the algorithms are also provided. This document may be updated to remain current with evolving lunar or other planetary surface operations, assumptions and concepts, and to provide additional data and analyses collected during the ongoing analog research program.

    During 2011 the LHCb experiment at CERN collected $1.0 {\\mbox{fb}^{-1}}$ of $\\sqrt{s} = 7 {\\mathrm{\\,Te\\kern -0.1em V}}$ $pp$ collisions. Due to the large heavy quark production cross-sections, these data provide unprecedented samples of heavy flavoured hadrons. The first results from LHCb have made a significant impact on the flavour physics landscape and have definitively proved the concept of a dedicated experiment in the forward region at a hadron collider. This document discusses the implications of these first measurements on classes of extensions to the Standard Model, bearing in mind the interplay with the results of searches for on-shell production of new particles at ATLAS and CMS. The physics potential of an upgrade to the LHCb detector, which would allow an order of magnitude more data to be collected, is emphasised.

  13. Clinical Implications of Antiviral Resistance in Influenza

    Directory of Open Access Journals (Sweden)

    Timothy C. M. Li


    Full Text Available Influenza is a major cause of severe respiratory infections leading to excessive hospitalizations and deaths globally; annual epidemics, pandemics, and sporadic/endemic avian virus infections occur as a result of rapid, continuous evolution of influenza viruses. Emergence of antiviral resistance is of great clinical and public health concern. Currently available antiviral treatments include four neuraminidase inhibitors (oseltamivir, zanamivir, peramivir, laninamivir, M2-inibitors (amantadine, rimantadine, and a polymerase inhibitor (favipiravir. In this review, we focus on resistance issues related to the use of neuraminidase inhibitors (NAIs. Data on primary resistance, as well as secondary resistance related to NAI exposure will be presented. Their clinical implications, detection, and novel therapeutic options undergoing clinical trials are discussed.

  14. Tumor dedifferentiation: diagnostic and therapeutic implications

    Directory of Open Access Journals (Sweden)

    Abhimanyu Jha


    Full Text Available Some of the neoplasm especially malignant tumors are notorious in masquerading their cell of origin because of additional mutations which drives them to differentiate into unusual phenotype. This is implicated to a phenomenon of tumor dedifferentiation which can mislead into inappropriate categorization and therapy. Dedifferentiation is well recognized in sarcomas such as liposarcoma, chondrosarcoma and MPNST. However, it can also develop in carcinomas, melanomas and lymphomas at initial diagnosis, following therapy or at recurrence.  The phenomenon has been reported in both primary tumors as well as at metastatic foci. A correct and early pathological identification of this phenomenon might profoundly help in guiding appropriate therapy. Clinical and radiological findings, immunohistochemistry and genetic analysis are often required for correct lineage identification of these tumors.

In particular, we have explored the possibility that the smallness of the observed neutrino masses is naturally understood in a modified version of the Standard Model (SM) with complete extra generations of fermions, i.e., that have right-handed neutrinos, in which neutrino masses are generated at two loops. With one extra family it is not possible to fit the observed spectrum of masses and mixings. However, the radiative mass generated provides an important constraint in these kind of models, so the neutrino masses do not exceed their cosmological bound. Within the context of two extra families, we analyse the allowed parameter space and the possible phenomenological signals.

  16. Exploring Forensic Implications of the Fusion Drive

    Directory of Open Access Journals (Sweden)

    Shruti Gupta


    Full Text Available This paper explores the forensic implications of Apple's Fusion Drive. The Fusion Drive is an example of auto-tiered storage. It uses a combination of a flash drive and a magnetic drive. Data is moved between the drives automatically to maximize system performance. This is different from traditional caches because data is moved and not simply copied. The research included understanding the drive structure, populating the drive, and then accessing data in a controlled setting to observe data migration strategies. It was observed that all the data is first written to the flash drive with 4 GB of free space always maintained. If data on the magnetic drive is frequently accessed, it is promoted to the flash drive while demoting other information. Data is moved at a block-level and not a file-level. The Fusion Drive didn't alter the timestamps of files with data migration.

  17. Destination image: Origins, Developments and Implications

    Directory of Open Access Journals (Sweden)

    Sérgio Dominique Ferreira Lopes


    Full Text Available Over the last few decades, tourism has become one of the main sectors of the global economy, not only because of its contribution to the Gross Domestic Product (GDP of different countries, but also because of the employment it generates. Since 2009, however, the results of tourism have been severely affected by the economic and financial crisis and it is now essential to analyze the key elements of tourist consumer behavior. In this context, the image that a destination transmits to the market becomes one of the elements which influence tourists the most when choosing a tourist destination. The authors therefore aim to identify the main elements that characterize the image of a tourist destination, as well as their implications for the management of tourist destinations.

  18. The antecedents and implications of interracial anxiety. (United States)

    Plant, E Ashby; Devine, Patricia G


    Drawing on previous theorizing from both the prejudice and social anxiety literatures, a model of the antecedents and implications of intergroup anxiety is offered. It is argued that a lack of positive previous experiences with outgroup members creates negative expectancies about interracial interactions, which result in intergroup anxiety. This anxiety is posited to result in heightened hostility toward outgroup members and a desire to avoid interacting with outgroup members. Study 1 examined White participants' responses to interacting with Black people using a range of self-report measures; the associations between these responses supported the relationships outlined in the model. Study 2 explored White participants' responses to an anticipated interaction with a Black person or a White person. The findings revealed that high levels of anxiety about an interaction with a Black person, but not a White person, were associated with a lower likelihood of returning for the interaction.

  19. Gestalt theory: implications for radiology education. (United States)

    Koontz, Nicholas A; Gunderman, Richard B


    The Gestalt theory of modern psychology is grounded in the ideas that holistic rather than atomistic approaches are necessary to understand the mind, and that the mental whole is greater than the sum of its component parts. Although the Gestalt school fell out of favor due to its descriptive rather than explanatory nature, it permanently changed our understanding of perception. For the radiologist, such fundamental Gestalt concepts as figure-ground relationships and a variety of "grouping principles" (the laws of closure, proximity, similarity, common region, continuity, and symmetry) are ubiquitous in daily work, not to mention in art and personal life. By considering the applications of these principles and the stereotypical ways in which humans perceive visual stimuli, a radiology learner may incur fewer errors of diagnosis. This article serves to introduce several important principles of Gestalt theory, identify examples of these principles in widely recognizable fine art, and highlight their implications for radiology education.

    Taylan Akgun


    Full Text Available The QRS represents the simultaneous activation of the right and left ventricles, although mostof the QRS waveform is derived from the larger left ventricular musculature. Although normalQRS duration is <100 millisecond (ms, its duration and shape are quite variable from patient topatient in idiopathic dilated cardiomyopathy (IDCM. Prolongation of QRS occurs in 14% to 47%of heart failure (HF patients. Left bundle branch block (LBBB is far more common than rightbundle branch block (RBBB. Dyssynchronous left ventricular activation due to LBBB and otherintraventricular conduction blocks provides the rationale for the use of cardiac resynchronizationtherapy with biventricular pacing in patients with IDCM. Fragmented QRS (fQRS is a markerof depolarization abnormality and present in significant number of the patients with IDCM andnarrow QRS complexes. It is associated with arrhythmic events and intraventricular dyssynchrony.The purpose of this manuscript is to present an overview on some clinical, echocardiographic andprognostic implications of various QRS morphologies in patients with IDCM.

  1. Therapeutic Implications of PPARγ in Cardiovascular Diseases

    Directory of Open Access Journals (Sweden)

    Hiroshi Hasegawa


    Full Text Available Peroxisome proliferator-activated receptor-γ (PPARγ is the members of the nuclear receptor superfamily as a master transcriptional factor that promotes differentiation of preadipocytes by activating adipose-specific gene expression. Although PPARγ is expressed predominantly in adipose tissue and associated with adipocyte differentiation and glucose homeostasis, PPARγ is also present in a variety of cell types including vascular cells and cardiomyocytes. Activation of PPARγ suppresses production of inflammatory cytokines, and there is accumulating data that PPARγ ligands exert antihypertrophy of cardiomyocytes and anti-inflammatory, antioxidative, and antiproliferative effects on vascular wall cells and cardiomyocytes. In addition, activation of PPARγ is implicated in the regulation of endothelial function, proliferation and migration of vascular smooth muscle cells, and activation of macrophages. Many studies suggest that PPARγ ligands not only ameliorate insulin sensitivity, but also have pleiotropic effects on the pathophysiology of atherosclerosis, cardiac hypertrophy, ischemic heart, and myocarditis.

  2. Motherhood in adolescents’ lives: Implications for action

    Directory of Open Access Journals (Sweden)

    Magaly Nóblega Mayorga


    Full Text Available Based on the findings from two qualitative studies, this article analyzes motherhood’s mean­ings for those young women living in poverty. One study explored motherhood’s meanings attributed by 25 mothers from 18 to 20 years old who had a pregnancy during adolescence. The other study examined social representations about the characteristics of early mother­hood in 24 non-parents men and women teenagers, in order to understand the culture in which the young mothers live. Results suggest that motherhood represents a positive change for most young women and it structures their identity. The implications of these findings for primary and secondary prevention in this field are discussed.

  3. Racism and cardiovascular disease: implications for nursing. (United States)

    Jackson, Jennifer; McGibbon, Elizabeth; Waldron, Ingrid


    The social determinants of health (SDH) are recognized as a prominent influence on health outcomes across the lifespan. Racism is identified as a key SDH. In this article, the authors describe the concept of racism as an SDH, its impact in discriminatory actions and inactions, and the implications for cardiovascular nurses. Although research in Canada on the links among racism, stress, and cardiovascular disease is limited, there is growing evidence about the stress of racism and its long-term impact on cardiovascular health. The authors discuss how cardiovascular nursing could be enhanced through an understanding of racism-related stress, and race-based differences in cardiovascular care. The authors conclude with strategies for action to address this nursing concern.

  4. Nursing Home Regulations Redefined: Implications for Providers. (United States)

    Unroe, Kathleen T; Ouslander, Joseph G; Saliba, Debra


    The Centers for Medicare and Medicaid Services (CMS) finalized a comprehensive update to nursing home requirements of participation in October 2016. Nearly 10,000 public comments were received regarding the proposed rule, and CMS made multiple modifications based on comments from providers, advocacy organizations, and others before issuing the final rule. The final rule describing nursing home requirements of participation modernizes nursing home regulation. It is being implemented in three phases-beginning in November 2016, November 2017, and November 2019. There are multiple provisions that have implications for clinicians caring for nursing home residents, particularly in terms of management of infections, medication prescribing and monitoring, and delegation of medical orders. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

  5. Implications of Orientation in Sheared Cocoa Butter (United States)

    Guthrie, Sarah E.; Mazzanti, Gianfranco; Marangoni, Alejandro; Idziak, Stefan H. J.


    We will present x-ray and mechanical studies of oriented phases of cocoa butter. The structural elements of foods play an important role in determining such things as quality and shelf stability. The specific structure and properties of cocoa butter, however, are complicated due to the ability of the cocoa butter to form crystals in six polymorphic forms. Recent work has shown that the application of shear not only accelerates the transitions to more stable polymorphs, but also causes orientation of the crystallites[1]. The implications of orientation on the structures formed under conditions of shear and cooling will be described using x-ray diffraction and mechanical measurements. 1 G. Mazzanti, S. E. Guthrie, E.

  7. Cosmological implications of the Machian principle. (United States)

    Fahr, Hans J; Zoennchen, Jochen H


    The famous idea of Ernst Mach concerning the non-absolute but relational character of particle inertia is taken up in this paper and is reinvestigated with respect to its cosmological implications. From Thirring's general relativistic study of the old Newtonian problem of the relativity of rotations in different reference systems, it appears that the equivalence principle with respect to rotating reference systems, if at all, can only be extended to the system of the whole universe, if the mass of the universe scales with the effective radius or extent of the universe. A reanalysis of Thirring's derivations still reveals this astonishing result, and thus the general question must be posed: how serious this result has to be taken with respect to cosmological implications. As we will show, the equivalence principle is, in fact, fulfilled by a universe with vanishing curvature, i.e. with a curvature parameter k = 0, which just has the critical density rho (crit) = (3H)(2)/8piG, where H is the Hubble constant. It turns out, however, that this principle can only permanently be fulfilled in an evolving cosmos, if the cosmic mass density, different from its conventional behaviour, varies with the reciprocal of the squared cosmic scale. This, in fact, would automatically be realized, if the mass of each cosmic particle scales with the scale of the universe. The latter fact, on one hand, is a field-theoretical request from a general relativistic field theory which fulfills H. Weyl's requirement of a conformal scale invariance. On the other hand, it can perhaps also be concluded on purely physical grounds, when taking into account that as source of the cosmic metrics only an effective mass density can be taken. This mass density represents the bare mass density reduced by its mass equivalent of gravitational self-binding energy. Some interesting cosmological conclusions connected with this fact are pointed out in this paper.

  8. Wheelchair propulsion biomechanics: implications for wheelchair sports. (United States)

    Vanlandewijck, Y; Theisen, D; Daly, D


    The aim of this article is to provide the reader with a state-of-the-art review on biomechanics in hand rim wheelchair propulsion, with special attention to sport-specific implications. Biomechanical studies in wheelchair sports mainly aim at optimising sport performance or preventing sport injuries. The sports performance optimisation question has been approached from an ergonomic, as well as a skill proficiency perspective. Sports medical issues have been addressed in wheelchair sports mainly because of the extremely high prevalence of repetitive strain injuries such as shoulder impingement and carpal tunnel syndrome. Sports performance as well as sports medical reflections are made throughout the review. Insight in the underlying musculoskeletal mechanisms of hand rim wheelchair propulsion has been achieved through a combination of experimental data collection under realistic conditions, with a more fundamental mathematical modelling approach. Through a synchronised analysis of the movement pattern, force generation pattern and muscular activity pattern, insight has been gained in the hand rim wheelchair propulsion dynamics of people with a disability, varying in level of physical activity and functional potential. The limiting environment of a laboratory, however, has hampered the drawing of sound conclusions. Through mathematical modelling, simulation and optimisation (minimising injury and maximising performance), insight in the underlying musculoskeletal mechanisms during wheelchair propulsion is sought. The surplus value of inverse and forward dynamic simulation of hand rim stroke dynamics is addressed. Implications for hand rim wheelchair sports are discussed. Wheelchair racing, basketball and rugby were chosen because of the significance and differences in sport-specific movement dynamics. Conclusions can easily be transferred to other wheelchair sports where movement dynamics are fundamental.

  17. Policy implications of technologies for cognitive enhancement

    Energy Technology Data Exchange (ETDEWEB)

    Sarewitz, Daniel R. (Arizona State University, Tempe, AZ); Karas, Thomas H.


    The Advanced Concepts Group at Sandia National Laboratory and the Consortium for Science, Policy and Outcomes at Arizona State University convened a workshop in May 2006 to explore the potential policy implications of technologies that might enhance human cognitive abilities. The group's deliberations sought to identify core values and concerns raised by the prospect of cognitive enhancement. The workshop focused on the policy implications of various prospective cognitive enhancements and on the technologies/nanotechnology, biotechnology, information technology, and cognitive science--that enable them. The prospect of rapidly emerging technological capabilities to enhance human cognition makes urgent a daunting array of questions, tensions, ambitions, and concerns. The workshop elicited dilemmas and concerns in ten overlapping areas: science and democracy; equity and justice; freedom and control; intergenerational issues; ethics and competition; individual and community rights; speed and deliberations; ethical uncertainty; humanness; and sociocultural risk. We identified four different perspectives to encompass the diverse issues related to emergence of cognitive enhancement technologies: (1) Laissez-faire--emphasizes freedom of individuals to seek and employ enhancement technologies based on their own judgment; (2) Managed technological optimism--believes that while these technologies promise great benefits, such benefits cannot emerge without an active government role; (3) Managed technological skepticism--views that the quality of life arises more out of society's institutions than its technologies; and (4) Human Essentialism--starts with the notion of a human essence (whether God-given or evolutionary in origin) that should not be modified. While the perspectives differ significantly about both human nature and the role of government, each encompasses a belief in the value of transparency and reliable information that can allow public discussion and

  18. Environmental implications and applications of nanomaterials (United States)

    Bhattacharya, Priyanka

    Recent advances in material science and nanotechnology have given rise to a myriad of developments, while in the meantime call for research into the impacts of nanomaterials on the environment and human health. Although considerable progress has been made in the past decade concerning the behavior of nanomaterials in biological systems, such understanding is critically lacking with respect to the fate of nanomaterials in ecosystems. Accordingly, this dissertation addresses the interactions between nanomaterials and algae---the major constituent of the aquatic food chain (Part I, Chapter two), and exploits the physicochemistry of nanoscaled synthetic dendritic polymers for environmental applications, especially for water purification that is a focused theme of the entire dossier (Part II, Chapters two--five). This dissertation is organized as follows. Chapter one presents a general review of the physical/physicochemical properties, characterizations, implications---especially ecological implication, and applications of a host of most produced and studied nanomaterials. In addition, advances in environmental applications of nanomaterials are discussed. Chapter two examines algal responses to two major types of engineered nanomaterials---quantum dots and polystyrene. Inhibited photosynthetic activities of green algae are observed as a result of the physical adsorption of the nanomaterials. Chapter three elucidates the physicochemical properties of poly(amidoamine)-tris(hydroxymethyl)amidomethane- and amine-terminated dendrimers towards their applications in water remediation. Here, the capacities and mechanisms of the dendrimers in hosting cationic copper, anionic nitrate, polyaromatic phenanthrene, and the more heterogeneous humic acids are discussed. Based on the results of Chapter three, Chapter four presents a dendrimer-based novel optical scheme for improving the detection sensitivity and selectivity of environmental pollutants. Specifically, the surface plasmon

  19. People management implications of virtual workplace arrangements

    Directory of Open Access Journals (Sweden)

    K. Ortlepp


    Full Text Available Purpose: The purpose of this paper is to investigate the factors that led to an organisation implementing a particular form of virtual workplace arrangement, namely, home-based work. The benefits and disadvantages associated with this form of work arrangement are explored from both the managers' and home-based employees' perspectives. Design/Methodology/Approach: Given the exploratory nature of the empirical study on which this paper is based, a qualitative research design was adopted so as to ensure that the data collection process was dynamic and probing in nature. Semi-structured in-depth interviews were therefore used as instruments for data collection. Findings: The research findings indicate that virtual work arrangements such as home-based work arrangements have advantages for both employers and employees. For instance, reduction of costs associated with office space and facilities, decrease in absenteeism rates, increased employee job satisfaction and improvements in employees' general quality of life. However, a number of negative experiences related to this form of virtual work arrangement are also evident, for example, feelings of isolation as well as stress related to the inability to have firm boundaries between work and family responsibilities. Implications: Based on the insights gained from the findings in the empirical study, a number of areas that need to be given specific attention when organisations are introducing virtual workplace arrangements of this nature are identified. Recommendations made in this article are important for human resource management specialists as well as core business policy makers considering different forms of organisational design. Originality/Value: Maximising the quality of production and service provided has become the prime objective in most organisations in the 21st century. Technology has made it possible for some jobs to be performed at any place at any time and has facilitated the

  20. Alexithymia in eating disorders: therapeutic implications

    Directory of Open Access Journals (Sweden)

    Pinna F


    Full Text Available Federica Pinna, Lucia Sanna, Bernardo Carpiniello Department of Public Health, Clinical and Molecular Medicine - Unit of Psychiatry, University of Cagliari, Cagliari, Italy Abstract: A high percentage of individuals affected by eating disorders (ED achieve incomplete recovery following treatment. In an attempt to improve treatment outcome, it is crucial that predictors of outcome are identified, and personalized care approaches established in line with new treatment targets, thus facilitating patient access to evidence-based treatments. Among the psychological factors proposed as predictors of outcome in ED, alexithymia is of outstanding interest. The objective of this paper is to undertake a systematic review of the literature relating to alexithymia, specifically in terms of the implications for treatment of ED. In particular, issues concerning the role of alexithymia as a predictor of outcome and as a factor to be taken into account in the choice of treatment will be addressed. The effect of treatments on alexithymia will also be considered. A search of all relevant literature published in English using PubMed, PsycINFO, and Scopus databases was carried out on the basis of the following keywords: alexithymia, anorexia nervosa, bulimia nervosa, eating disorders, and treatment; no time limits were imposed. Despite the clinical relevance of alexithymia, the number of studies published on the above cited aspects is somewhat limited, and these studies are largely heterogeneous and feature significant methodological weaknesses. Overall, data currently available mostly correlate higher levels of alexithymia with a less favorable outcome in ED. Accordingly, alexithymia is seen as a relevant treatment target with the aim of achieving recovery of these patients. Treatments focusing on improving alexithymic traits, and specifically those targeting emotions, seem to show greater efficacy, although alexithymia levels often remain high even after specific

  1. On the normative implications of social neuroscience

    Directory of Open Access Journals (Sweden)

    Arleen Salles


    Full Text Available Within the last decades, brain science has been offering new insights into the relationship among diverse psychological processes and the neural correlates of our moral thought and behavior. Despite the distinction between the explanatory/descriptive nature of science and the normative nature of morality, some neuroethicists have claimed that neuroscientific findings have normative implications. In this paper, I identify three interpretations of the claim. The first focuses on neuroscience’s role in explaining the origin of morality and of moral values and how neurobiology is the bases of moral behavior. A second version is about the role that neuroscientific knowledge can play in showing the psychological plausibility of the moral psychology underlying some ethical approaches. Finally, a third version advances that neuroscience could play a role in determining the moral plausibility of some normative approaches. My aim is to delineate each version and highlight the issues raised to suggest that while neuroscience might provide information regarding the nature of moral reasoning, its role in the normative discussion itself is still quite limited.

  2. Language Learning Strategies: Classification and Pedagogical Implication

    Directory of Open Access Journals (Sweden)

    Ag. Bambang Setiyadi


    Full Text Available Many studies have been conducted to explore language learning strategies (Rubin, 1975, Naiman et . al ., 1978; Fillmore, 1979; O'Malley et . al ., 1985 and 1990; Politzer and Groarty, 1985; Prokop, 1989; Oxford, 1990; and Wenden, 1991. In the current study a total of 79 university students participating in a 3 month English course participated. This study attempted to explore what language learning strategies successful learners used and to what extent the strategies contributed to success in learning English in Indonesia . Factor analyses, accounting for 62.1 %, 56.0 %, 41.1 %, and 43.5 % of the varience of speaking, listening, reading and writing measures in the language learning strategy questionnaire, suggested that the questionnaire constituted three constructs. The three constructs were named metacognitive strategies, deep level cognitive and surface level cognitive strategies. Regression analyses, performed using scales based on these factors revealed significant main effects for the use of the language learning strategies in learning English, constituting 43 % of the varience in the posttest English achievement scores. An analysis of varience of the gain scores of the highest, middle, and the lowest groups of performers suggested a greater use of metacognitive strategies among successful learners and a greater use of surface level cognitive strategies among unsuccessful learners. Implications for the classroom and future research are also discussed.

  3. Biological behaviour and clinical implications of micrometastases.

    LENUS (Irish Health Repository)

    Kell, M R


    BACKGROUND: The most important prognostic determinant in cancer is the identification of disseminated tumour burden (metastases). Micrometastases are microscopic (smaller than 2 mm) deposits of malignant cells that are segregated spatially from the primary tumour and depend on neovascular formation (angiogenesis) to propagate. METHODS: The electronic literature (1966 to present) on micrometastases and their implications in malignant melanoma and epithelial cancers was reviewed. RESULTS: Immunohistochemical techniques combined with serial sectioning offer the best accuracy for detection of nodal micrometastases. Molecular techniques should be reserved for blood samples or bone marrow aspirates. Detection of micrometastases in regional lymph nodes and\\/or bone marrow confers a poor prognosis in epithelial cancers. The concept of sentinel node biopsy combined with serial sectioning and dedicated screening for micrometastases may improve staging procedures. Strategies against angiogenesis may provide novel therapies to induce and maintain micrometastatic dormancy. CONCLUSION: The concept of micrometastases has resulted in a paradigm shift in the staging of epithelial tumours and our overall understanding of malignant processes.

  4. Microbiota—implications for immunity and transplantation. (United States)

    Bromberg, Jonathan S; Fricke, W Florian; Brinkman, C Colin; Simon, Thomas; Mongodin, Emmanuel F


    Each individual harbours a unique set of commensal microorganisms, collectively referred to as the microbiota. Notably, these microorganisms exceed the number of cells in the human body by 10-fold. This finding has accelerated a shift in our understanding of human physiology, with the realization that traits necessary for health are both encoded and influenced by the human genome and the microbiota. Our understanding of the aetiology of complex diseases has, therefore, evolved with increasing awareness that the human microbiota has an active and critical role in maintaining health and inducing disease. Indeed, findings from bioinformatic studies indicate that the microbiota and microbiome have multiple effects on the innate and adaptive immune systems, with effects on infection, autoimmune disease and cancer. In this Review, we first address the important statistical and informatics aspects that should be considered when characterizing the composition of microbiota. We next highlight the effects of the microbiota on the immune system and the implications of these effects on organ failure and transplantation. Finally, we reflect on the future perspectives for studies of the microbiota, including novel diagnostic tests and therapeutics.

  5. Surgical orodental implications in ankylosing spondylitis

    Mohammad Mehdizadeh


    Full Text Available Temporomandibular joint and the pelvic complex are bidirectionally related. Ankylosing spondylitis (AS is a seronegative arthropathy with the key feature of bony fusion of lumbar vertebrae. A 39 year old known case of AS was presented to private office for left lower impacted third molar surgical removal. Previously, he was rejected to receive oral care for pulpectomy and extraction due to limited mouth opening. Prior to the surgery, lateral neck radiography was obtained to exclude any subluxation of fracture of cervical vertebrae. Neck was supported to insure neck stability during surgical forces. In addition, considering consumption of immunosuppressive medications including corticosteroids, procedure was performed with a great care, with attention to higher possibility of infection and fracture. Access to the surgical site was not desirable, though surgery accomplished without any significant event and the patient discharged with routine analgesic and antibiotics recommendation. Sometimes, impaired access to the oral cavity in patients with AS leads to receive suboptimal or minimal orodental care. Long list of dental implications in these patients may be simplified by considering of careful neck and jaw support, applying at least possible forces and great attention to the infection control rules. It is wised to be performed under patient and skilled hands.

  6. Legal implications of genetics and crime research. (United States)

    Denno, D W


    Two controversial topics dominate discussions of the legal implications of genetics and crime research; (1) the viability and politics of such research, which has sparked fervent debate in the USA; and (2) the current status of new or atypical criminal law defences, which would include a genetic-defect defence to criminal behaviour. This chapter begins by examining the scientifically discredited XYY chromosome syndrome defence, the major genetic-defect defence that defendants have attempted, albeit unsuccessfully. It then focuses on attorneys' efforts to test for evidence of genetic abnormality in the recent and highly publicized case involving convicted murderer Stephen Mobley, whose family history reveals four generations of violent, aggressive and behaviourally disordered men and women. Mobley is currently appealing his death sentence before the Georgia Supreme Court on the basis that the trial court denied his request both to have genetic testing performed and to have such testing allowed as evidence into court. This chapter concludes by emphasizing that the question is not whether genetic evidence will ever be admitted into court, but when and under what kinds of circumstances. No doubt, genetic evidence, and comparable kinds of biological evidence, will have a major impact on juries when such evidence is more fully accepted by the legal and scientific communities.

  7. The Implications of Deep Mitigation Pathways (United States)

    Calvin, K. V.


    The 21st Conference of Parties to the UNFCCC agreement called for limiting climate change to "well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C." A climate target of 1.5°C places a stringent constraint on allowable emissions over the twenty-first century. Roegli et al. (2015) set that constraint at 200-415 GtCO2 between 2011 and 2100 for a likely chance of staying below 1.5°C in 2100. Limiting emissions to these levels requires that global emissions peak and decline over the coming decades, with net negative global emissions by mid-century. This level of decarbonization requires dramatic shifts in the energy and agricultural sectors, and comes at significant economic costs. This talk explores the effect of mitigating climate change to 1.5°C on the economy, energy system, and terrestrial system. We quantify the required deployment of various low carbon technologies, as well as the amount of existing capital that is abandoned in an effort to limit emissions. We show the shifts required in the terrestrial system, including its contribution to carbon sequestration through afforestation and bioenergy. Additionally, we show the implications of deep mitigation pathways on energy, food, and carbon prices. We contrast these results with a reference, no climate policy, world and a 2°C.

  8. Japan's aging population. Implications for healthcare. (United States)

    Oliver, A J; Ikegami, N; Ikeda, S


    In the early years of the next century, the Japanese population may well become the oldest in the world. The Japanese government's concentration on post-World War II economic expansion meant that the government only fully woke up to the financial implications of having a large elderly population when oil prices were raised in the 1970s, highlighting Japan's economic dependence on global markets. This article explains the process by which policy regarding Japan's elderly developed both before and after these oil price increases. The measures of healthcare cost containment that the government introduced in response to the increased financial pressure are described, with a particular focus on pharmaceuticals. This article shows that the government has achieved a degree of success in terms of containing pharmaceutical costs, but that future effects on the quality of healthcare are uncertain. Ultimately, a wider application of a per diem fee in place of the prevalent fee-for-service system, and the realisation of plans to improve the social service infrastructure, would be the best path for policy to follow.

  9. Vesicular secretion of auxin: Evidences and implications. (United States)

    Baluska, Frantisek; Schlicht, Markus; Volkmann, Dieter; Mancuso, Stefano


    The plant hormone auxin is secreted in root apices via phospholipase Dzeta2 (PLDzeta2) activity which produces specific population of phosphatidic acid that stimulates secretion of vesicles enriched with auxin. These vesicles were reported to be localized at plant synapses which are active in auxin secretion, especially at the transition zone of the root apex. There are several implications of this vesicular secretion of auxin. In root apices, auxin emerges as plant neurotransmitter-like signal molecule which coordinates activities of adjacent cells via electric and chemical signaling. Putative quantal release of auxin after electrical stimulation, if confirmed, would be part of neuronal communication between plant cells. As auxin transport across plant synapses is tightly linked with integrated sensory perception of environment, especially of omnipresent gravity and light, this process is proposed to mediate the plant perception of environment. These neuronal features allow sessile plants to integrate multitude of sensory signals into the adaptive behavior of whole plants and the animal-like exploratory behavior of growing roots.

  10. Framework and implications of virtual neurorobotics. (United States)

    Goodman, Philip H; Zou, Quan; Dascalu, Sergiu-Mihai


    Despite decades of societal investment in artificial learning systems, truly "intelligent" systems have yet to be realized. These traditional models are based on input-output pattern optimization and/or cognitive production rule modeling. One response has been social robotics, using the interaction of human and robot to capture important cognitive dynamics such as cooperation and emotion; to date, these systems still incorporate traditional learning algorithms. More recently, investigators are focusing on the core assumptions of the brain "algorithm" itself-trying to replicate uniquely "neuromorphic" dynamics such as action potential spiking and synaptic learning. Only now are large-scale neuromorphic models becoming feasible, due to the availability of powerful supercomputers and an expanding supply of parameters derived from research into the brain's interdependent electrophysiological, metabolomic and genomic networks. Personal computer technology has also led to the acceptance of computer-generated humanoid images, or "avatars", to represent intelligent actors in virtual realities. In a recent paper, we proposed a method of virtual neurorobotics (VNR) in which the approaches above (social-emotional robotics, neuromorphic brain architectures, and virtual reality projection) are hybridized to rapidly forward-engineer and develop increasingly complex, intrinsically intelligent systems. In this paper, we synthesize our research and related work in the field and provide a framework for VNR, with wider implications for research and practical applications.

  11. Implications of conformal invariance in momentum space (United States)

    Bzowski, Adam; McFadden, Paul; Skenderis, Kostas


    We present a comprehensive analysis of the implications of conformal invariance for 3-point functions of the stress-energy tensor, conserved currents and scalar operators in general dimension and in momentum space. Our starting point is a novel and very effective decomposition of tensor correlators which reduces their computation to that of a number of scalar form factors. For example, the most general 3-point function of a conserved and traceless stress-energy tensor is determined by only five form factors. Dilatations and special conformal Ward identities then impose additional conditions on these form factors. The special conformal Ward identities become a set of first and second order differential equations, whose general solution is given in terms of integrals involving a product of three Bessel functions (`triple- K integrals'). All in all, the correlators are completely determined up to a number of constants, in agreement with well-known position space results. In odd dimensions 3-point functions are finite without renormalisation while in even dimensions non-trivial renormalisation in required. In this paper we restrict ourselves to odd dimensions. A comprehensive analysis of renormalisation will be discussed elsewhere. This paper contains two parts that can be read independently of each other. In the first part, we explain the method that leads to the solution for the correlators in terms of triple- K integrals while the second part contains a self-contained presentation of all results. Readers interested only in results may directly consult the second part of the paper.

  12. Human genetic information: the legal implications. (United States)

    Brahams, D


    This paper provides a brief summary of some of the key legal issues raised by human genetic information and research as viewed from a British common law standpoint. The law is basically reactive rather than prospective and problems posed by futuristic medico-scientific discoveries are likely to be dealt with by reference to established legal principles and analogies made with decided cases. The acquisition and research into human genetic information in the form of DNA profiling may have wide-ranging legal implications. Human genetic information may provide an evidential tool in the legal process when the identity of a specific individual or his family connections and relationships are called into question. It may also pose problems of confidentiality which could conflict with a duty of disclosure. In the future it may be possible to identify a propensity to develop a disease which may be seriously disabling or terminal long before any symptoms are detectable. This sensitive information could be of considerable interest to any prospective employer, insurer, marriage partner or family member and is of serious concern to the individual himself. How far should or could such information lawfully be made available and to whom? Legal debates are also likely to focus on ownership of human genetic information, the patenting of techniques to unravel it, and therapies and medicines developed therefrom. The law will be invoked to safeguard any intellectual property which may exist and to patent any inventive steps in the field.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. Enamel Pearls Implications on Periodontal Disease

    Directory of Open Access Journals (Sweden)

    Elton Gonçalves Zenóbio


    Full Text Available Dental anatomy is quite complex and diverse factors must be taken into account in its analysis. Teeth with anatomical variations present an increase in the rate of severity periodontal tissue destruction and therefore a higher risk of developing periodontal disease. In this context, this paper reviews the literature regarding enamel pearls and their implications in the development of severe localized periodontal disease as well as in the prognosis of periodontal therapy. Radiographic examination of a patient complaining of pain in the right side of the mandible revealed the presence of a radiopaque structure around the cervical region of lower right first premolar. Periodontal examination revealed extensive bone loss since probing depths ranged from 7.0 mm to 9.0 mm and additionally intense bleeding and suppuration. Surgical exploration detected the presence of an enamel pearl, which was removed. Assessment of the remaining supporting tissues led to the extraction of tooth 44. Local factors such as enamel pearls can lead to inadequate removal of the subgingival biofilm, thus favoring the establishment and progression of periodontal diseases.

  14. Conservation Documentation and the Implications of Digitisation

    Directory of Open Access Journals (Sweden)

    Michelle Moore


    Full Text Available Conservation documentation can be defined as the textual and visual records collected during the care and treatment of an object. It can include records of the object's condition, any treatment done to the object, any observations or conclusions made by the conservator as well as details on the object's past and present environment. The form of documentation is not universally agreed upon nor has it always been considered an important aspect of the conservation profession. Good documentation tells the complete story of an object thus far and should provide as much information as possible for the future researcher, curator, or conservator. The conservation profession will benefit from digitising its documentation using software such as databases and hardware like digital cameras and scanners. Digital technology will make conservation documentation more easily accessible, cost/time efficient, and will increase consistency and accuracy of the recorded data, and reduce physical storage space requirements. The major drawback to digitising conservation records is maintaining access to the information for the future; the notorious pace of technological change has serious implications for retrieving data from any machine- readable medium.

  15. Extremophile Diatoms: Implications to the Drake Equation (United States)

    Sterrenburg, Frithjof A. S.; Hoover, Richard B.


    Diatoms are unicellular Eukaryotes that (as a group and phylogenetically) are not strictly regarded as extremophiles , since the vast majority of diatoms are mesophilic photoautotrophs. However, among the terrestrial Eukaryotes, diatoms are by far the single group of organisms with the ability to inhabit the greatest range of hostile environments on Earth. They are the dominant eukaryotes in the polar regions; in fumaroles, hot springs and geysers; and in hypersaline and hyperalkaline lakes and pools. Cryophilic species such as Fragilaria sublinearis and Chaetoceras fragilis are able to carry out respiration at extremely low rates at low temperatures in darkness. The Drake Equation refers to the likelihood of there being intelligent life at the technological level of electromagnetic communication. However, consideration of the range of conditions suitable for the habitability of eukaryotic diatoms and prokaryotic extremophiles, the likelihood that life exists elsewhere in the cosmos becomes many orders of magnitude greater than that predicted by the classical Drake Equation. In this paper we review the characteristics of diatoms as eukaryotic extremophiles and consider the implications to adjustments needed to the Drake Equation to assess the possibility that life exists elsewhere in the Universe.

  16. Amazonian foods and implications for human biology. (United States)

    Dufour, Darna L; Piperata, Barbara A; Murrieta, Rui S S; Wilson, Warren M; Williams, Drake D


    Diets of subsistence-based Amazonian populations have been linked to local resources, but are changing with market penetration. To review the available data on traditional Amazonian foods and diets and evaluate their implications for human biology as a step toward understanding nutrition transitions in the region. This study used the Human Relations Area Files for information on the diets of Amerindian groups in the Amazon Basin from 1950 to the present, and used other published sources and the authors' own data. Data on food use was identified for only nine groups and dietary intake data for individuals in only three of the groups. A diet based on starchy staples (manioc and plantains) and fish, supplemented with a limited variety of other plant and animal foods, was found. Bitter manioc-based foods were associated with the consumption of cyanogens and fish with the consumption of mercury. Diets of adults appear to be adequate in energy and protein and low in fats. Children's diets were not well documented. Based on the limited available data, Amazonian diets are restricted in variety, but appear to be adequate in energy and protein for adults, but likely insufficiently nutrient-dense for children.

  17. The public health implications of melioidosis

    Directory of Open Access Journals (Sweden)

    Timothy J.J. Inglis

    Full Text Available Melioidosis, which is caused by the bacterium Burkholderia pseudomallei, is a potentially fatal tropical infection, little known outside its main endemic zone of Southeast Asia and northern Australia. Though it has received more attention in recent years on account of its claimed suitability as a biological weapon agent, the principal threat from melioidosis is a result of naturally occurring events. Occasional case clusters, sporadic cases outside the known endemic zone and infections in unusual demographic groups highlight a changing epidemiology. As melioidosis is the result of an environmental encounter and not person-to-person transmission, subtle changes in its epidemiology indicate a role environmental factors, such as man-made disturbances of soil and surface water. These have implications for travel, occupational and tropical medicine and in particular for risk assessment and prevention. Practical problems with definitive laboratory diagnosis, antibiotic treatment and the current lack of a vaccine underline the need for prevention through exposure avoidance and other environmental health measures. It is likely that the increasing population burden of the tropical zone and extraction of resources from the humid tropics will increase the prevalence of melioidosis. Climate change-driven extreme weather events will both increase the prevalence of infection and gradually extend its main endemic zone.

  18. Effects of Odor on Emotion, with Implications

    Directory of Open Access Journals (Sweden)

    Mikiko eKadohisa


    Full Text Available The sense of smell is found widely in the animal kingdom. Human and animal studies show that odor perception is modulated by experience and/or physiological state (such as hunger, and that some odors can arouse emotion, and can lead to the recall of emotional memories. Further, odors can influence psychological and physiological states. Individual odorants are mapped via gene-specified receptors to corresponding glomeruli in the olfactory bulb, which directly projects to the piriform cortex and the amygdala without a thalamic relay. The odors to which a glomerulus responds reflect the chemical structure of the odorant. The piriform cortex and the amygdala both project to the orbitofrontal cortex which with the amygdala is involved in emotion and associative learning, and to the entorhinal/hippocampal system which is involved in long-term memory including episodic memory. Evidence that some odors can modulate emotion and cognition is described, and the possible implications for the treatment of psychological problems, for example in reducing the effects of stress, are considered.

  20. Rehabilitation of executive functions: Implications and strategies

    Directory of Open Access Journals (Sweden)

    Bruno Kluwe-Schiavon


    Full Text Available Executive Functions (EF concern a range of abilities including problem-solving, planning, initiation, selfmonitoring,conscious attention, cope with new situations and the ability to modify plans if necessary. It’s a high cognitive function that is crucial for a person to get engaged and maintain daily activities whilst keeping a good quality of life. Problems in the EF were formerly known as Dysexecutive Syndrome (DS. There are many models concerning DS, although the literature on the subject still remains unclear. Several works appoint the effects brought by elderly life, as well as abuse of drugs and some psychopathologies. These factors are known to increase the distress of the frontal circuits and that could be associated to executive deficits. The effects of DS would compromise individuals in day-to-day routine, academic, social and labor fields. There is a growing body of studies trying to determine the causes, implications, associations and the best way to take care of these effects. This work intends to review DS, focusing on the most important fields related to this area, such as psychopathology associations, cognitive reserve, assessment and cognitive rehabilitation programs.

  1. Big Data: Implications for Health System Pharmacy. (United States)

    Stokes, Laura B; Rogers, Joseph W; Hertig, John B; Weber, Robert J


    Big Data refers to datasets that are so large and complex that traditional methods and hardware for collecting, sharing, and analyzing them are not possible. Big Data that is accurate leads to more confident decision making, improved operational efficiency, and reduced costs. The rapid growth of health care information results in Big Data around health services, treatments, and outcomes, and Big Data can be used to analyze the benefit of health system pharmacy services. The goal of this article is to provide a perspective on how Big Data can be applied to health system pharmacy. It will define Big Data, describe the impact of Big Data on population health, review specific implications of Big Data in health system pharmacy, and describe an approach for pharmacy leaders to effectively use Big Data. A few strategies involved in managing Big Data in health system pharmacy include identifying potential opportunities for Big Data, prioritizing those opportunities, protecting privacy concerns, promoting data transparency, and communicating outcomes. As health care information expands in its content and becomes more integrated, Big Data can enhance the development of patient-centered pharmacy services.

  2. Stress and eating behaviour: implications for obesity. (United States)

    Scott, Clare; Johnstone, Alexandra M


    This report outlines our strategy to examine the influence of workplace stress on eating behaviour, discussing the current literature which explores the relationship between stress and eating behaviour. This research aims to add to and develop the current understanding of the links between stress and eating behaviour. Specifically the aims are to examine the effect of workplace stress in both day workers and shift workers and their subsequent eating behaviour. The effect of healthy working environment initiatives on stress and eating behaviour will also be examined by comparing a workplace with such an initiative to one with no such initiative. The role of personality on both eating behaviour and stress susceptibility will be examined. In order to achieve this, 450 individuals from 3 public sector workplaces will be recruited. Anthropometric measurements (waist-hip ratio, BMI, visceral fat percentage) will be assessed, as well as personality, eating behaviour profiles, food intake (7-day weighed intake food diary) and both individual daily stressors as well as workplace stress assessed using the demand/control model of job strain will be assessed. Implications for policy and future research are also discussed. Copyright © 2012 S. Karger AG, Basel.

  3. Clinical implication of latent myofascial trigger point. (United States)

    Celik, Derya; Mutlu, Ebru Kaya


    Myofascial trigger points (MTrPs) are hyperirritable points located within a taut band of skeletal muscle or fascia, which cause referred pain, local tenderness and autonomic changes when compressed. There are fundamental differences between the effects produced by the two basic types of MTrPs (active and latent). Active trigger points (ATrPs) usually produce referred pain and tenderness. In contrast, latent trigger points (LTrPs) are foci of hyperirritability in a taut band of muscle, which are clinically associated with a local twitch response, tenderness and/or referred pain upon manual examination. LTrPs may be found in many pain-free skeletal muscles and may be "activated" and converted to ATrPs by continuous detrimental stimuli. ATrPs can be inactivated by different treatment strategies; however, they never fully disappear but rather convert to the latent form. Therefore, the diagnosis and treatment of LTrPs is important. This review highlights the clinical implication of LTrPs.

  4. Managed care implications in managing rheumatoid arthritis. (United States)

    Owens, Gary M


    Rheumatoid arthritis (RA) is a systemic inflammatory form of arthritis characterized by joint inflammation, pain, swelling, and stiffness. While contemporary treatment strategies based on early diagnosis, aggressive treatment, and regular monitoring have helped a significant number of patients achieve evidence-based treatment goals, RA still presents substantial management challenges to both clinicians and patients, and has the potential to lead to severe disability over time. In addition to its significant clinical consequences, RA has important economic implications. Both direct and indirect medical costs associated with RA are significant, including costs of medications, ambulatory and office-based care, and quality-of-life and productivity costs. In addition, a significant proportion of patients with prevalent RA have associated cardiovascular disease and other comorbidities, further compounding healthcare costs and complicating management of this disorder. Clinically favorable and cost-effective management must focus on prevention of disease progression and the improved patient health status and productivity than can result from optimal disease control. With the myriad of treatment options both available and emerging, managed care organizations are faced with difficult decisions surrounding the most clinically and cost-effective allocation of treatments designed to improve disease outcomes for patients with RA. It is vital that managed care clinicians and providers analyze both the overall burden and the specific costs of RA. This will allow a better understanding of how costs and issues relating to healthcare utilization affect the treatment of patients with RA and impact individualized therapy, care coordination, and outcomes.

  5. Environmental implications and applications of engineered ... (United States)

    This review focus on environmental implications and applications of engineered magnetite (Fe3O4) nanoparticles (MNPs) as a single phase or a component of a hybrid nanocomposite that take advantages of their superparamagnetism and high surface area. MNPs are synthesized via co-precipitation, thermal decomposition, hydrothermal process, emulsion, and microbial process. Aggregation/sedimentation and transport of MNPs depend on surface charge of MNPs and geochemical parameters such as pH, ionic strength, and organic matter. MNPs generally have low toxicity to humans and ecosystem. MNPs are used for making excellent anode electrode materials in lithium-ion battery, for constructing biosensors, and for catalyzing a variety of chemical reactions. MNPs are used for air cleanup and carbon sequestration. MNP nanocomposites are made as antimicrobial agent for water disinfection and flocculants for water treatment. Conjugated MNPs are widely used for adsorptive/separative removal of organics, dye, oil, arsenic, Cr(VI), heavy metals, radionuclides, and rare earth elements. MNPs can degrade organic/inorganic contaminants via chemical reduction or oxidation in water, sediment, and soil. Future studies should further explore mechanisms of MNP interactions with other nanomaterials and contaminants, economic and green approaches of MNP synthesis, and field scale demonstration of MNP utilization.

  6. Medical implications of elder abuse and neglect. (United States)

    Dong, XinQi


    Recognition of elder abuse and neglect among health care professionals has been a relatively recent phenomenon. Each year, millions of elderly persons suffer as the result of abuse and neglect. Their quality of life is severely jeopardized in the form of worsened functional status and progressive dependency, poorly rated self-health, feelings of helplessness, and from the vicious cycle of social isolation, stress and further psychologic decline. Other medical implications of abuse and neglect include higher health systems use in the form of frequent ER visits, higher hospitalization, and higher nursing home placement; most importantly, it is an independent predictor for higher mortality. Physicians are well situated in detecting and reporting suspected cases and taking care of the frail elders who are victims of abuse and neglect, but there are barriers on the individual level, and there is a broader need for system change. Through education, training, and reinforcement, there are strategies to get health care professionals more involved and provide effective management protocols and guidelines for us to advocate for our patients in the current epidemic of elder abuse and neglect.

  7. Online customer experience: Implications for digital banking

    Directory of Open Access Journals (Sweden)

    Štavljanin Velimir


    Full Text Available Banks will be facing great challenges in the coming period. Some of these challenges are a lack of differentiation, disloyal customers, new non-traditional competitors, increased interaction and expectations from digital channels. Many consulting firms, but also the academic community, propose a solution in the form of implementing the concept of customer experience management. As research shows that a large number of challenges come from the online environment, it is necessary for banks to ensure excellence in the online environment by applying the concept of online customer experience. In order to create this experience, it is up to the banks to meet all the necessary antecedents, which can involve the elements in terms of control, processes and content. This can be a very difficult job if one is unfamiliar with the basics, but it could also be a rewarding job which will reflect on the business performance. Although the focus of the paper is online customer experience, even in the developed countries 'digital' customers are rare. Most of them are multichannel oriented and an important aspect is the multichannel integration and the strategy focused on customer experience. This paper presents an overview of the literature in the field of online customer experience, with the aim of introducing the public with the concept as well as presenting the implications which this concept has for digital banking.

  8. Environmental health implications of global climate change

    Energy Technology Data Exchange (ETDEWEB)

    Watson, Robert T.; Patz, Jonathan; Gubler, Duane J.; Parson, Edward A.; Vincent, James H.


    This paper reviews the background that has led to the now almost-universally held opinion in the scientific community that global climate change is occurring and is inescapably linked with anthropogenic activity. The potential implications to human health are considerable and very diverse. These include, for example, the increased direct impacts of heat and of rises in sea level, exacerbated air and water-borne harmful agents, and - associated with all the preceding - the emergence of environmental refugees. Vector-borne diseases, in particular those associated with blood-sucking arthropods such as mosquitoes, may be significantly impacted, including redistribution of some of those diseases to areas not previously affected. Responses to possible impending environmental and public health crises must involve political and socio-economic considerations, adding even greater complexity to what is already a difficult challenge. In some areas, adjustments to national and international public health practices and policies may be effective, at least in the short and medium terms. But in others, more drastic measures will be required. Environmental monitoring, in its widest sense, will play a significant role in the future management of the problem. (Author)

  9. Psychological implications of admission to critical care. (United States)

    Pattison, Natalie

    Admission to critical care can have far-reaching psychological effects because of the distinct environment. Critical care services are being re-shaped to address long-term sequelae, including post-traumatic stress disorder, anxiety and depression. The long-term consequences of critical illness not only cost the individual, but also have implications for society, such as diminished areas of health-related quality-of-life in sleep, reduced ability to return to work and enjoy recreational activities (Audit Commission, 1999; Hayes et al, 2000). The debate around the phenomenon of intensive care unit (ICU) syndrome is discussed with reference to current thinking. After critical care, patients may experience amnesia, continued hallucinations or flashbacks, anxiety, depression, and dreams and nightmares. Nursing care for patients while in the critical care environment can have a positive effect on psychological well-being. Facilitating communication, explaining care and rationalizing interventions, ensuring patients are oriented as to time and place, reassuring patients about transfer, providing patients,where possible, with information about critical care before admission and considering anxiolytic use, are all practices that have a beneficial effect on patient care. Follow-up services can help patients come to terms with their experiences of critical illness and provide the opportunity for them to access further intervention if desired. Working towards providing optimal psychological care will have a positive effect on patients' psychological recovery and may also help physical recuperation after critical care.

  10. Environmental implications of increased biomass energy use

    Energy Technology Data Exchange (ETDEWEB)

    Miles, T.R. Sr.; Miles, T.R. Jr. (Miles (Thomas R.), Portland, OR (United States))


    This study reviews the environmental implications of continued and increased use of biomass for energy to determine what concerns have been and need to be addressed and to establish some guidelines for developing future resources and technologies. Although renewable biomass energy is perceived as environmentally desirable compared with fossil fuels, the environmental impact of increased biomass use needs to be identified and recognized. Industries and utilities evaluating the potential to convert biomass to heat, electricity, and transportation fuels must consider whether the resource is reliable and abundant, and whether biomass production and conversion is environmentally preferred. A broad range of studies and events in the United States were reviewed to assess the inventory of forest, agricultural, and urban biomass fuels; characterize biomass fuel types, their occurrence, and their suitability; describe regulatory and environmental effects on the availability and use of biomass for energy; and identify areas for further study. The following sections address resource, environmental, and policy needs. Several specific actions are recommended for utilities, nonutility power generators, and public agencies.

  11. Prostate cancer epigenetics and its clinical implications

    Directory of Open Access Journals (Sweden)

    Srinivasan Yegnasubramanian


    Full Text Available Normal cells have a level of epigenetic programming that is superimposed on the genetic code to establish and maintain their cell identity and phenotypes. This epigenetic programming can be thought as the architecture, a sort of cityscape, that is built upon the underlying genetic landscape. The epigenetic programming is encoded by a complex set of chemical marks on DNA, on histone proteins in nucleosomes, and by numerous context-specific DNA, RNA, protein interactions that all regulate the structure, organization, and function of the genome in a given cell. It is becoming increasingly evident that abnormalities in both the genetic landscape and epigenetic cityscape can cooperate to drive carcinogenesis and disease progression. Large-scale cancer genome sequencing studies have revealed that mutations in genes encoding the enzymatic machinery for shaping the epigenetic cityscape are among the most common mutations observed in human cancers, including prostate cancer. Interestingly, although the constellation of genetic mutations in a given cancer can be quite heterogeneous from person to person, there are numerous epigenetic alterations that appear to be highly recurrent, and nearly universal in a given cancer type, including in prostate cancer. The highly recurrent nature of these alterations can be exploited for development of biomarkers for cancer detection and risk stratification and as targets for therapeutic intervention. Here, we explore the basic principles of epigenetic processes in normal cells and prostate cancer cells and discuss the potential clinical implications with regards to prostate cancer biomarker development and therapy.

  12. Epigenetics and its implications for ecotoxicology. (United States)

    Vandegehuchte, Michiel B; Janssen, Colin R


    Epigenetics is the study of mitotically or meiotically heritable changes in gene function that occur without a change in the DNA sequence. Interestingly, epigenetic changes can be triggered by environmental factors. Environmental exposure to e.g. metals, persistent organic pollutants or endocrine disrupting chemicals has been shown to modulate epigenetic marks, not only in mammalian cells or rodents, but also in environmentally relevant species such as fish or water fleas. The associated changes in gene expression often lead to modifications in the affected organism's phenotype. Epigenetic changes can in some cases be transferred to subsequent generations, even when these generations are no longer exposed to the external factor which induced the epigenetic change, as observed in a study with fungicide exposed rats. The possibility of this phenomenon in other species was demonstrated in water fleas exposed to the epigenetic drug 5-azacytidine. This way, populations can experience the effects of their ancestors' exposure to chemicals, which has implications for environmental risk assessment. More basic research is needed to assess the potential phenotypic and population-level effects of epigenetic modifications in different species and to evaluate the persistence of chemical exposure-induced epigenetic effects in multiple subsequent generations. © Springer Science+Business Media, LLC 2011

  13. Environmental implications of carbon limits on market ... (United States)

    Combined heat and power (CHP) is promoted as an economical, energy-efficient option for combating climate change. To fully examine the viability of CHP as a clean-technology solution, its market potential and impacts need to be analyzed as part of scenarios of the future energy system, particularly those with policies limiting greenhouse gas (GHG) emissions. This paper develops and analyzes scenarios using a bottom-up, technology rich optimization model of the U.S. energy system. Two distinct carbon reduction goals were set up for analysis. In Target 1, carbon emission reduction goals were only included for the electric sector. In Target 2, carbon emission reduction goals were set across the entire energy system with the target patterned after the U.S.’s commitment to reducing GHG emissions as part of the Paris Agreement reached at the COP21 summit. From a system-wide carbon reduction standpoint, Target 2 is significantly more stringent. In addition, these scenarios examine the implications of various CHP capacity expansion and contraction assumptions and energy prices. The largest CHP capacity expansion are observed in scenarios that included Target 1, but investments were scaled back in scenarios that incorporated Target 2. The latter scenario spurred rapid development of zero-emissions technologies within the electric sector, and purchased electricity increased dramatically in many end-use sectors. The results suggest that CHP may play a role in a carbon-c

  14. Polycystic ovary syndrome: clinical implication in perimenopause

    Directory of Open Access Journals (Sweden)

    Monika Lenart-Lipińska


    Full Text Available Polycystic ovary syndrome (PCOS, a hyperandrogenic disorder, is the commonest endocrinopathy in premenopausal women. This syndrome is associated with fertility problems, clinical manifestations of hyperandrogenism and metabolic disturbances, particularly insulin resistance and obesity. There is a great body of evidence that patients with PCOS present multiple cardiovascular risk factors and cluster components of metabolic syndrome from early ages. The presence of comorbidities such as abdominal obesity, insulin resistance, type 2 diabetes, hypertension places these females at an increased risk of future cardiovascular events. However, the extent to which PCOS components are present in perimenopausal women and the degree to which PCOS increases various risk factors in addition to the known risk of the perimenopausal period have not been fully determined. The perimenopausal period per se is associated with weight gain and an increased cardiovascular risk, which may be additionally aggravated by the presence of metabolic disturbances connected with PCOS. The phenotype of PCOS may improve with aging and it is still uncertain whether the presence of PCOS significantly increases the cardiovascular risk later in women’s life. Most recent data suggest that the prevalence of cardiovascular diseases and the related long-term consequences in females with PCOS seem to be lower than expected. This manuscript reviews long-term consequences of PCOS and considers their clinical implications in perimenopause.

  15. Clinical implications of vitamin D deficiency

    Full Text Available Vitamin D deficiency is a common medical problem worldwide and its prevalence rises along with latitude, obesity, sedentary lifestyle, limited sunlight exposure and aging. A great body of evidence has shown that patients with vitamin D deficiency have increased cardiovascular risks and total mortality. Conversely, the presence of comorbidities progressive with age such as abdominal obesity, insulin resistance, type 2 diabetes and hypertension places the patients at an increased risk of vitamin D deficiency. The multidirectional effect of vitamin D deficiency is present in different phases of the aging process. Based on the literature review, the risk factors for vitamin D insufficiency most often found in post-menopausal women include limited sun exposure and time spent outdoors, inadequate dietary vitamin D intake, winter season and increased age. Vitamin D supplementation in this group might offer prevention of falls and fractures and may be beneficial for cardiovascular health, what may be especially important in osteoporotic and elderly populations. Prevention and treatment processes involve education regarding sunlight exposure and pharmacological cholecalciferol supplementation according to the recommendations for Central Europe. This manuscript reviews the role of vitamin D and its deficiency and considers their clinical implications, with particular regard to peri- and postmenopausal women.

  16. Serotonin and migraine: biology and clinical implications. (United States)

    Hamel, E


    Migraine is the most frequent neurological disorder in the adult population worldwide, affecting up to 12% of the general population and more frequent in women ( approximately 25%). It has a high impact on our society due to its disabling nature and, therein, reduced quality of life and increased absenteeism from work. Headache is the primary clinical manifestation and it has been associated with 'a hereditary or predisposed sensitivity of neurovascular reactions to certain stimuli or to cyclic changes in the central nervous system' (1). Amongst the many neurotransmitters in the brain, the serotonergic (serotonin, 5-HT) system from the brainstem raphe nucleus has been most convincingly implicated in migraine pathophysiology. The documented changes in 5-HT metabolism and in the processing of central 5-HT-mediated responses during and in between migraine attacks have led to the suggestion that migraine is a consequence of a central neurochemical imbalance that involves a low serotonergic disposition. Although the exact cascade of events that link abnormal serotonergic neurotransmission to the manifestation of head pain and the accompanying symptoms has yet to be fully understood, recent evidence suggests that a low 5-HT state facilitates activation of the trigeminovascular nociceptive pathway, as induced by cortical spreading depression. In this short review, we present and discuss the original and most recent findings that support a role for altered serotonergic neurotransmission in the manifestation of migraine headache.

  17. Superoxide Ion: Generation and Chemical Implications. (United States)

    Hayyan, Maan; Hashim, Mohd Ali; AlNashef, Inas M


    Superoxide ion (O2(•-)) is of great significance as a radical species implicated in diverse chemical and biological systems. However, the chemistry knowledge of O2(•-) is rather scarce. In addition, numerous studies on O2(•-) were conducted within the latter half of the 20th century. Therefore, the current advancement in technology and instrumentation will certainly provide better insights into mechanisms and products of O2(•-) reactions and thus will result in new findings. This review emphasizes the state-of-the-art research on O2(•-) so as to enable researchers to venture into future research. It comprises the main characteristics of O2(•-) followed by generation methods. The reaction types of O2(•-) are reviewed, and its potential applications including the destruction of hazardous chemicals, synthesis of organic compounds, and many other applications are highlighted. The O2(•-) environmental chemistry is also discussed. The detection methods of O2(•-) are categorized and elaborated. Special attention is given to the feasibility of using ionic liquids as media for O2(•-), addressing the latest progress of generation and applications. The effect of electrodes on the O2(•-) electrochemical generation is reviewed. Finally, some remarks and future perspectives are concluded.

  18. Prostate cancer epigenetics and its clinical implications. (United States)

    Yegnasubramanian, Srinivasan


    Normal cells have a level of epigenetic programming that is superimposed on the genetic code to establish and maintain their cell identity and phenotypes. This epigenetic programming can be thought as the architecture, a sort of cityscape, that is built upon the underlying genetic landscape. The epigenetic programming is encoded by a complex set of chemical marks on DNA, on histone proteins in nucleosomes, and by numerous context-specific DNA, RNA, protein interactions that all regulate the structure, organization, and function of the genome in a given cell. It is becoming increasingly evident that abnormalities in both the genetic landscape and epigenetic cityscape can cooperate to drive carcinogenesis and disease progression. Large-scale cancer genome sequencing studies have revealed that mutations in genes encoding the enzymatic machinery for shaping the epigenetic cityscape are among the most common mutations observed in human cancers, including prostate cancer. Interestingly, although the constellation of genetic mutations in a given cancer can be quite heterogeneous from person to person, there are numerous epigenetic alterations that appear to be highly recurrent, and nearly universal in a given cancer type, including in prostate cancer. The highly recurrent nature of these alterations can be exploited for development of biomarkers for cancer detection and risk stratification and as targets for therapeutic intervention. Here, we explore the basic principles of epigenetic processes in normal cells and prostate cancer cells and discuss the potential clinical implications with regards to prostate cancer biomarker development and therapy.

  19. Karyomorphology of Taiwanese Begonia (Begoniaceae): taxonomic implications. (United States)

    Oginuma, Kazuo; Peng, Ching-I


    The karyomorphology of all 14 species of Taiwanese Begonia was investigated to elucidate their chromosome features and chromosomal evolution. Among all species investigated, differences in chromosome features are found in: (1) chromosome number 2 n = 22, 26, 36, 38, 52, 60, 64, 82, and (2) frequencies of chromosomes with secondary, tertiary, and/or small constrictions of polyploids, ranging from 23% to 63%, which is higher than the expected value of about 9%. It is suggested that after polyploidization from the diploid species (i.e., 2 n = 22 and frequencies of chromosomes with secondary, tertiary, and/or small constrictions of polyploids of about 9%), chromosome translocations occurred, followed by a decrease in chromosome number, and subsequently stabilized genomes were formed in various species in Taiwan. The karyomorphological evidence also suggested that the chromosome morphology has evolved in parallel in the begonias belonging to different sections in Taiwan. The variation in chromosomal features is more complex than the variation in floral and fruit morphologies. Karyomorphological data also supports the recognition of five new species in Taiwan: Begonia bouffordii, B. chuyunshanensis, B. pinglinensis, B. tengchiana, and B. wutaiana. Based on detailed karyomorphological analyses, the taxonomic implications, speciation, and chromosomal evolution in Taiwanese Begoniaare discussed.

  20. Framework and implications of virtual neurorobotics

    Directory of Open Access Journals (Sweden)


    Full Text Available Despite decades of societal investment in artificial learning systems, truly “intelligent” systems have yet to be realized. These traditional models are based on input-output pattern optimization and/or cognitive production rule modeling. One response has been social robotics, using the interaction of human and robot to capture important cognitive dynamics such as cooperation and emotion; to date, these systems still incorporate traditional learning algorithms. More recently, investigators are focusing on the core assumptions of the brain “algorithm” itself—trying to replicate uniquely “neuromorphic” dynamics such as action potential spiking and synaptic learning. Only now are large-scale neuromorphic models becoming feasible, due to the availability of powerful supercomputers and an expanding supply of parameters derived from research into the brain’s interdependent electrophysiological, metabolomic and genomic networks. Personal computer technology has also led to the acceptance of computer-generated humanoid images, or “avatars”, to represent intelligent actors in virtual realities. In a recent paper, we proposed a method of virtual neurorobotics (VNR in which the approaches above (social-emotional robotics, neuromorphic brain architectures, and virtual reality projection are hybridized to rapidly forward-engineer and develop increasingly complex, intrinsically intelligent systems. In this paper, we synthesize our research and related work in the field and provide a framework for VNR, with wider implications for research and practical applications.

  1. Implications Of A Heavy Gauge Boson

    CERN Document Server

    Kang, J


    We study the implications of neutral heavy gauge bosons to electroweak (EW) baryogenesis, neutrino physics and the discovery limits at the Tevatron and LHC. For baryogenesis, we construct two anomaly free supersymmetric U(1)′ models with secluded U(1) ′-breaking sectors. In the framework of the one with E6 embedding, we study the one-loop effective potential at finite temperature, and show that there exist strong enough first order EW phase transition (EWPT) because of the large trilinear terms in the tree- level Higgs potentials. Unlike the Minimal Supersymmetric Standard Model (MSSM), the stop masses can be very heavy. We discuss possible large tree-level CP violation associated with the Higgs sector. Numerical calculations show that the contribution purely from the thin wall regime is big enough to explain the observed baryon number asymmetry for some of the parameter space. Our model is free of domain wall problems and does not introduce new contributions to electric dipole moments (...

  2. Monitoring gaseous exchange: implications for nursing care. (United States)

    Martin, Susan; Wilson, Michael


    The purpose of this study is to examine whether a relationship exists between arterial and end-tidal carbon dioxide tension (PaCO2 and PETCO2 respectively) in patients admitted to intensive care units (ICUs), and what the implications it has for nursing care. PaCO2 and PETCO2 are indicators of ventilatory adequacy which is an important aspect of respiratory function. These measures of carbon dioxide tension are obtained via invasive and non-invasive monitoring tools. Measurement of PETCO2 has only recently been introduced into ICUs and its usefulness in these environments is open to debate. A population of 30 intubated patients had 214 simultaneous measurements of PaCO2 and PETCO2 taken over a period of 10 months. The findings indicate that, despite strong significant correlations, PETCO2 cannot be used safely as a substitute for PaCO2 as the arterial/end-tidal carbon dioxide gradient is not constant, nor does capnography provide a consistently reliable indicator of PaCO2.

  3. Science and religion: implications for science educators (United States)

    Reiss, Michael J.


    A religious perspective on life shapes how and what those with such a perspective learn in science; for some students a religious perspective can hinder learning in science. For such reasons Staver's article is to be welcomed as it proposes a new way of resolving the widely perceived discord between science and religion. Staver notes that Western thinking has traditionally postulated the existence and comprehensibility of a world that is external to and independent of human consciousness. This has led to a conception of truth, truth as correspondence, in which our knowledge corresponds to the facts in this external world. Staver rejects such a conception, preferring the conception of truth as coherence in which the links are between and among independent knowledge claims themselves rather than between a knowledge claim and reality. Staver then proposes constructivism as a vehicle potentially capable of resolving the tension between religion and science. My contention is that the resolution between science and religion that Staver proposes comes at too great a cost—both to science and to religion. Instead I defend a different version of constructivism where humans are seen as capable of generating models of reality that do provide richer and more meaningful understandings of reality, over time and with respect both to science and to religion. I argue that scientific knowledge is a subset of religious knowledge and explore the implications of this for science education in general and when teaching about evolution in particular.

    Directory of Open Access Journals (Sweden)



    Full Text Available In terms of economic policy, three new aspects are important in the current context of globalization which brings forward new strategies regarding the outsourcing and offshoring of activities and functions of the value chain. These aspects refer to the instant appearance of an offshore transferable function , to the unpredictability of winning and losing functions and to the lowering of competition from the levels of sector, company or professional qualification category to an individual level. Of the three features, the most problematic for policy makers is the unpredictability of the impact of globalization. For example, in Europe we can not reasonably believe that workers in the most competitive sectors will be in a position of winners, nor that these winners will be the most prepared or trained in analytical functions. Many European workers currently work at prices fixed by the local market and not covered by productivity. But when the competition on functions will expand through globalization outside the country or area, their choices will be either a job loss or a reduction in salary. The question that will be raised ever insistently will be the following: what jobs are more exposed to this new competition? On the one hand, offshoring is on balance positive for Western economies, because it makes domestic companies more competitive. At the same time the material outsourcing is, for most developed economies, much more important than the outsourcing of services and the implications for labor market must be objectively differentiated in the two sectors. On the other hand, if we take into account the amplification of the effects that offshoring already has on the structure and distribution of labor, the socio-economic European policy of labor orientation to the coordinates of a "knowledge based" economy and to the jobs of the "information society" could be wrong.

  2. CHO Quasispecies—Implications for Manufacturing Processes

    Directory of Open Access Journals (Sweden)

    Florian M. Wurm


    Full Text Available Chinese hamster ovary (CHO cells are a source of multi-ton quantities of protein pharmaceuticals. They are, however, immortalized cells, characterized by a high degree of genetic and phenotypic diversity. As is known for any biological system, this diversity is enhanced by selective forces when laboratories (no sharing of gene pools grow cells under (diverse conditions that are practical and useful. CHO cells have been used in culture for more than 50 years, and various lines of cells are available and have been used in manufacturing. This article tries to represent, in a cursory way, the history of CHO cells, particularly the origin and subsequent fate of key cell lines. It is proposed that the name CHO represents many different cell types, based on their inherent genetic diversity and their dynamic rate of genetic change. The continuing remodeling of genomic structure in clonal or non-clonal cell populations, particularly due to the non-standardized culture conditions in hundreds of different labs renders CHO cells a typical case for “quasispecies”. This term was coined for families of related (genomic sequences exposed to high mutation rate environments where a large fraction of offspring is expected to carry one or more mutations. The implications of the quasispecies concept for CHO cells used in protein manufacturing processes are significant. CHO genomics/transcriptomics may provide only limited insights when done on one or two “old” and poorly characterized CHO strains. In contrast, screening of clonal cell lines, derived from a well-defined starting material, possibly within a given academic or industrial environment, may reveal a more narrow diversity of phenotypes with respect to physiological/metabolic activities and, thus, allow more precise and reliable predictions of the potential of a clone for high-yielding manufacturing processes.

  3. Implications of climate change for potamodromous fishes. (United States)

    Beatty, Stephen J; Morgan, David L; Lymbery, Alan J


    There is little understanding of how climate change will impact potamodromous freshwater fishes. Since the mid 1970s, a decline in annual rainfall in south-western Australia (a globally recognized biodiversity hotspot) has resulted in the rivers of the region undergoing severe reductions in surface flows (ca. 50%). There is universal agreement amongst Global Climate Models that rainfall will continue to decline in this region. Limited data are available on the movement patterns of the endemic freshwater fishes of south-western Australia or on the relationship between their life histories and hydrology. We used this region as a model to determine how dramatic hydrological change may impact potamodromous freshwater fishes. Migration patterns of fishes in the largest river in south-western Australia were quantified over a 4 year period and were related to a number of key environmental variables including discharge, temperature, pH, conductivity and dissolved oxygen. Most of the endemic freshwater fishes were potamodromous, displaying lateral seasonal spawning migrations from the main channel into tributaries, and there were significant temporal differences in movement patterns between species. Using a model averaging approach, amount of discharge was clearly the best predictor of upstream and downstream movement for most species. Given past and projected reductions in surface flow and groundwater, the findings have major implications for future recruitment rates and population viabilities of potamodromous fishes. Freshwater ecosystems in drying climatic regions can only be managed effectively if such hydro-ecological relationships are considered. Proactive management and addressing existing anthropogenic stressors on aquatic ecosystems associated with the development of surface and groundwater resources and land use is required to increase the resistance and resilience of potamodromous fishes to ongoing flow reductions. © 2013 John Wiley & Sons Ltd.

  5. Developmental implications of nonlinear phonological theory. (United States)

    Bernhardt, B


    For the past 20 years the field of linguistics has provided a basis for assessment and treatment methods for speech and language disorders. Since Goldsmiths (1976) dissertation showing tone as an independently functioning autosegment, new and robust phonological frameworks have become available, i.e. nonlinear phonological frameworks. This paper outlines major aspects of nonlinear phonology and its developmental implications. Based in generative phonology, nonlinear frameworks adhere to many of the tenets of the generative grammar tradition, such as markedness and autonomy of linguistic components. The major difference between classical and nonlinear generative phonology is the latters emphasis on representation rather than on rules or processes. This enriched representation is hierarchical and multitiered, rather than being strictly sequential as in classical generative phonology, and includes syllabic structure and segmental information. Phonological rules or processes result from, and are constrained by, principles of association between the various autonomous levels. If a child comes to the language-learning situation with a representional framework, a set of universal 'templates' are then available to utilize for decoding and encoding. The incorporation of both syllabic (prosodic level) and segmental information in representation suggests that the child will come to the language-learning process primed with expected syllable structure bases as well as with an expected segmental 'feature inventory'. The concept of autonomy implies possible independent learning for information on the various tiers, e.g. between the prosodic and segmental levels. The concept of hierarchy suggests that prominent system units in tree structure may have developmental precedence over deeply embedded units. These and other concepts are developed in the following pages.

  6. Biomechanical implications of walking with indigenous footwear. (United States)

    Willems, Catherine; Stassijns, Gaetane; Cornelis, Wim; D'Août, Kristiaan


    This study investigates biomechanical implications of walking with indigenous "Kolhapuri" footwear compared to barefoot walking among a population of South Indians. Ten healthy adults from South India walked barefoot and indigenously shod at voluntary speed on an artificial substrate. The experiment was repeated outside, on a natural substrate. Data were collected from (1) a heel-mounted 3D-accelerometer recording peak impact at heel contact, (2) an ankle-mounted 3D-goniometer (plantar/dorsiflexion and inversion/eversion), and (3) sEMG electrodes at the m. tibialis anterior and the m. gastrocnemius medialis. Data show that the effect of indigenous footwear on the measured variables, compared to barefoot walking, is relatively small and consistent between substrates (even though subjects walked faster on the natural substrate). Walking barefoot, compared to shod walking yields higher impact accelerations, but the differences are small and only significant for the artificial substrate. The main rotations of the ankle joint are mostly similar between conditions. Only the shod condition shows a faster ankle rotation over the rapid eversion motion on the natural substrate. Maximal dorsiflexion in late stance differs between the footwear conditions on an artificial substrate, with the shod condition involving a less dorsiflexed ankle, and the plantar flexion at toe-off is more extreme when shod. Overall the activity pattern of the external foot muscles is similar. The indigenous footwear studied (Kolhapuri) seems to alter foot biomechanics only in a subtle way. While offering some degree of protection, walking in this type of footwear resembles barefoot gait and this type of indigenous footwear might be considered "minimal". © 2017 The Authors American Journal of Physical Anthropology Published by Wiley Periodicals, Inc.

  7. Neuroimmunological Implications of AQP4 in Astrocytes

    Directory of Open Access Journals (Sweden)

    Hiroko Ikeshima-Kataoka


    Full Text Available The brain has high-order functions and is composed of several kinds of cells, such as neurons and glial cells. It is becoming clear that many kinds of neurodegenerative diseases are more-or-less influenced by astrocytes, which are a type of glial cell. Aquaporin-4 (AQP4, a membrane-bound protein that regulates water permeability is a member of the aquaporin family of water channel proteins that is expressed in the endfeet of astrocytes in the central nervous system (CNS. Recently, AQP4 has been shown to function, not only as a water channel protein, but also as an adhesion molecule that is involved in cell migration and neuroexcitation, synaptic plasticity, and learning/memory through mechanisms involved in long-term potentiation or long-term depression. The most extensively examined role of AQP4 is its ability to act as a neuroimmunological inducer. Previously, we showed that AQP4 plays an important role in neuroimmunological functions in injured mouse brain in concert with the proinflammatory inducer osteopontin (OPN. The aim of this review is to summarize the functional implication of AQP4, focusing especially on its neuroimmunological roles. This review is a good opportunity to compile recent knowledge and could contribute to the therapeutic treatment of autoimmune diseases through strategies targeting AQP4. Finally, the author would like to hypothesize on AQP4’s role in interaction between reactive astrocytes and reactive microglial cells, which might occur in neurodegenerative diseases. Furthermore, a therapeutic strategy for AQP4-related neurodegenerative diseases is proposed.

  8. Neurobiology and clinical implications of lucid dreaming. (United States)

    Mota-Rolim, Sérgio A; Araujo, John F


    Several lines of evidence converge to the idea that rapid eye movement sleep (REMS) is a good model to foster our understanding of psychosis. Both REMS and psychosis course with internally generated perceptions and lack of rational judgment, which is attributed to a hyperlimbic activity along with hypofrontality. Interestingly, some individuals can become aware of dreaming during REMS, a particular experience known as lucid dreaming (LD), whose neurobiological basis is still controversial. Since the frontal lobe plays a role in self-consciousness, working memory and attention, here we hypothesize that LD is associated with increased frontal activity during REMS. A possible way to test this hypothesis is to check whether transcranial magnetic or electric stimulation of the frontal region during REMS triggers LD. We further suggest that psychosis and LD are opposite phenomena: LD as a physiological awakening while dreaming due to frontal activity, and psychosis as a pathological intrusion of dream features during wake state due to hypofrontality. We further suggest that LD research may have three main clinical implications. First, LD could be important to the study of consciousness, including its pathologies and other altered states. Second, LD could be used as a therapy for recurrent nightmares, a common symptom of depression and post-traumatic stress disorder. Finally, LD may allow for motor imagery during dreaming with possible improvement of physical rehabilitation. In all, we believe that LD research may clarify multiple aspects of brain functioning in its physiological, altered and pathological states. Copyright © 2013 The Authors. Published by Elsevier Ltd..

  9. Brain microbleeds: Epidemiology and clinical implications. (United States)

    Boyano, I; Bravo, N; Miranda, J; Gil-Gregorio, P; Olazarán, J


    Brain microbleeds (BMB) are haemosiderin deposits contained within macrophages, which are displayed as hypointense images in some T2-weighted magnetic resonance imaging sequences. There are still many questions to be answered about the pathophysiology and clinical relevance of BMB. We conducted a literature review of the main epidemiological, clinical, and anatomical pathology studies of BMB performed in the general population, in patients at risk of or already suffering from a vascular disease, and in patients with cognitive impairment. We analysed the prevalence of BMB, risk factors, and potential pathophysiological mechanisms and clinical implications. The prevalence of BMB is highly variable (3%-27% in the general population, 6%-80% in patients with vascular risk factors or vascular disease, and 16%-45% in patients with cognitive impairment). BMB are associated with ageing, Alzheimer disease (AD), and in particular haemorrhagic or ischaemic cerebrovascular disease. The pathological substrate of BMB is either lipohyalinosis (subcortical BMB) or cerebral amyloid angiopathy (lobar BMB). BMB exacerbate cognitive impairment, possibly through cortical-subcortical and intracortical disconnection, and increase the risk of death, mostly due to vascular causes. BMB also increase the risk of cerebral haemorrhage, particularly in patients with multiple lobar BMB (probable erebral amyloid angiopathy). Therefore, anticoagulant treatment may be contraindicated in these patients. In patients with lower risk of bleeding, the new oral anticoagulants and the combination of clinical and magnetic resonance imaging follow-up could be helpful in the decision-making process.

  10. Ethical implications of HIV self-testing. (United States)

    Youngs, Jonathan; Hooper, Carwyn


    In April 2015, the first legally approved HIV self-testing kit went on sale in the UK-except Northern Ireland where they remain illegal. These tests allow individuals to test their HIV status and read the result in the privacy of their own home, much like a home pregnancy test. This paper explores the ethical implications of HIV self-testing. We conclude that there are no strong ethical objections to self-testing being made widely available in the UK. Pretest counselling for an HIV test is not an ethical necessity, and self-testing has the potential to increase early diagnosis of HIV infection and thus improve prognosis and reduce ongoing transmission. Self-testing kits might also empower people and promote autonomy by allowing people to dictate the terms on which they test their HIV status. We accept that there are some potential areas of concern. These include the possibility of user error with the tests, and the concern that individuals may not present to health services following a reactive result. False negatives have the potential to cause harm if the 'window period' is not understood, and false positives might produce psychological distress. There is, however, little evidence to suggest that self-testing kits will cause widespread harm, and we argue that the only way to properly evaluate whether they do cause significant harm is to carefully evaluate their use, now that they are available on the market.

  11. Synthetic Cannabinoids: Epidemiology, Pharmacodynamics, and Clinical Implications* (United States)

    Castaneto, Marisol S.; Gorelick, David A.; Desrosiers, Nathalie A.; Hartman, Rebecca L.; Pirard, Sandrine; Huestis, Marilyn A.


    Background Synthetic cannabinoids (SC) are a heterogeneous group of compounds developed to probe the endogenous cannabinoid system or as potential therapeutics. Clandestine laboratories subsequently utilized published data to develop SC variations marketed as abuseable “designer drugs.” In the early 2000’s, SC became popular as “legal highs” under brand names such as “Spice” and “K2,” in part due to their ability to escape detection by standard cannabinoid screening tests. The majority of SC detected in herbal products have greater binding affinity to the cannabinoid CB1 receptor than does Δ9-tetrahydrocannabinol (THC), the primary psychoactive compound in the cannabis plant, and greater affinity at the CB1 than the CB2 receptor. In-vitro and animal in-vivo studies show SC pharmacological effects 2-100 times more potent than THC, including analgesic, anti-seizure, weight-loss, anti-inflammatory, and anti-cancer growth effects.

  12. The endocannabinoid system and cancer: therapeutic implication. (United States)

    Guindon, Josée; Hohmann, Andrea G


    The endocannabinoid system is implicated in a variety of physiological and pathological conditions (inflammation, immunomodulation, analgesia, cancer and others). The main active ingredient of cannabis, Δ(9) -tetrahydrocannabinol (Δ(9) -THC), produces its effects through activation of CB(1) and CB(2) receptors. CB(1) receptors are expressed at high levels in the central nervous system (CNS), whereas CB(2) receptors are concentrated predominantly, although not exclusively, in cells of the immune system. Endocannabinoids are endogenous lipid-signalling molecules that are generated in the cell membrane from phospholipid precursors. The two best characterized endocannabinoids identified to date are anandamide (AEA) and 2-arachidonoylglycerol (2-AG). Here we review the relationship between the endocannabinoid system and anti-tumour actions (inhibition of cell proliferation and migration, induction of apoptosis, reduction of tumour growth) of the cannabinoids in different types of cancer. This review will focus on examining how activation of the endocannabinoid system impacts breast, prostate and bone cancers in both in vitro and in vivo systems. The therapeutic potential of cannabinoids for cancer, as identified in clinical trials, is also discussed. Identification of safe and effective treatments to manage and improve cancer therapy is critical to improve quality of life and reduce unnecessary suffering in cancer patients. In this regard, cannabis-like compounds offer therapeutic potential for the treatment of breast, prostate and bone cancer in patients. Further basic research on anti-cancer properties of cannabinoids as well as clinical trials of cannabinoid therapeutic efficacy in breast, prostate and bone cancer is therefore warranted. © 2011 The Authors.

    Synthetic cannabinoids (SC) are a heterogeneous group of compounds developed to probe the endogenous cannabinoid system or as potential therapeutics. Clandestine laboratories subsequently utilized published data to develop SC variations marketed as abusable designer drugs. In the early 2000s, SC became popular as "legal highs" under brand names such as Spice and K2, in part due to their ability to escape detection by standard cannabinoid screening tests. The majority of SC detected in herbal products have greater binding affinity to the cannabinoid CB1 receptor than does Δ(9)-tetrahydrocannabinol (THC), the primary psychoactive compound in the cannabis plant, and greater affinity at the CB1 than the CB2 receptor.

  14. Biosimilars: Implications for health-system pharmacists. (United States)

    Lucio, Steven D; Stevenson, James G; Hoffman, James M


    An update on scientific and regulatory challenges in the rapidly evolving field of biosimilar product development is presented. The U.S. market for biosimilar products (i.e., highly similar "follow-on" versions of approved biological drugs) is expected to expand with establishment of an expedited-approval pathway for biosimilars similar to that implemented in European Union countries eight years ago. In 2012, the Food and Drug Administration (FDA) published draft guidance clarifying the requirements of the biosimilars approval pathway; although no biosimilar has yet been approved via that pathway, FDA is engaged in ongoing meetings with a number of potential applicants. Due to molecular differences between innovator products and biosimilar versions, biosimilars are highly sensitive to manufacturing changes that can potentially have important safety and efficacy implications. Establishing the interchangeability of biosimilar and innovator drugs may be difficult at first, and it is possible that some biosimilars might not carry all the same indications for which the reference drug is approved. Pharmaceutical cost savings attained through the use of biosimilars are expected to average 20-30%. With several top-selling biologicals likely to lose patent exclusivity by 2020, health systems should prepare for the availability of new biosimilars by addressing formulary management and therapeutic interchange issues, pharmacovigilance and patient safety concerns, and related financial and operational issues. Over the coming years, biosimilars will present opportunities for health care organizations to manage the growth of pharmaceutical expenditures. Pharmacists can play a key role in preparing health systems for projected rapid expansion in the use of biosimilars and associated medication-use policy challenges.

  15. Discovering indigenous science: Implications for science education (United States)

    Snively, Gloria; Corsiglia, John


    Indigenous science relates to both the science knowledge of long-resident, usually oral culture peoples, as well as the science knowledge of all peoples who as participants in culture are affected by the worldview and relativist interests of their home communities. This article explores aspects of multicultural science and pedagogy and describes a rich and well-documented branch of indigenous science known to biologists and ecologists as traditional ecological knowledge (TEK). Although TEK has been generally inaccessible, educators can now use a burgeoning science-based TEK literature that documents numerous examples of time-proven, ecologically relevant, and cost effective indigenous science. Disputes regarding the universality of the standard scientific account are of critical importance for science educators because the definition of science is a de facto gatekeeping device for determining what can be included in a school science curriculum and what cannot. When Western modern science (WMS) is defined as universal it does displace revelation-based knowledge (i.e., creation science); however, it also displaces pragmatic local indigenous knowledge that does not conform with formal aspects of the standard account. Thus, in most science classrooms around the globe, Western modern science has been taught at the expense of indigenous knowledge. However, because WMS has been implicated in many of the world's ecological disasters, and because the traditional wisdom component of TEK is particularly rich in time-tested approaches that foster sustainability and environmental integrity, it is possible that the universalist gatekeeper can be seen as increasingly problematic and even counter productive. This paper describes many examples from Canada and around the world of indigenous people's contributions to science, environmental understanding, and sustainability. The authors argue the view that Western or modern science is just one of many sciences that need to be

    Toledo, Manuel; Sarria-Estrada, Silvana; Quintana, Manuel; Maldonado, Xavier; Martinez-Ricarte, Francisco; Rodon, Jordi; Auger, Cristina; Salas-Puig, Javier; Santamarina, Estevo; Martinez-Saez, Elena


    The role of seizures and antiepileptic treatments associated with glioblastoma is a current topic of discussion. The objective of this study is to characterize and establish implications of epilepsy associated with glioblastoma. We retrospectively analyzed the medical history, focused on epileptic features of 134 histologically diagnosed glioblastoma over a period of 4 years. The sample group had an average age of 56 years and 66% were male. Complete tumor resection was performed in 66% and 64.2% received further radio-oncologic treatment. The average survival rate was 12.4 months and 11.5% survived to 5 years. Epileptic seizures were the presentation symptom in 27% of cases and 51% suffered seizures during the disease, 26% become drug-resistant. Focal evolving to a bilateral convulsive seizures were the most frequent type. Epileptic seizures at presentation independently predicted longer survival (pepilepsy or seizures during disease improved survival. Late onset seizures, recurrences or status epilepticus during the course of the disease indicated tumor progression or the final stages of life. Prophylactic antiepileptic drugs did not prevent seizures. Similarly, there was no difference in survival between patients who did not use antiepileptic drugs and those using valproate or levetiracetam. Patients under 60 years, full oncologic treatment and secondary glioblastomas were factors that improved survival (pepilepsy or the onset of seizures as a presentation symptom in glioblastomas predict longer survival. Half of patients have seizures during the course of the disease. Antiepileptic drugs alone do not increase survival in glioblastoma patients. Copyright © 2015 Elsevier B.V. All rights reserved.

  17. Physiological Implications of Myocardial Scar Structure. (United States)

    Richardson, William J; Clarke, Samantha A; Quinn, T Alexander; Holmes, Jeffrey W


    Once myocardium dies during a heart attack, it is replaced by scar tissue over the course of several weeks. The size, location, composition, structure, and mechanical properties of the healing scar are all critical determinants of the fate of patients who survive the initial infarction. While the central importance of scar structure in determining pump function and remodeling has long been recognized, it has proven remarkably difficult to design therapies that improve heart function or limit remodeling by modifying scar structure. Many exciting new therapies are under development, but predicting their long-term effects requires a detailed understanding of how infarct scar forms, how its properties impact left ventricular function and remodeling, and how changes in scar structure and properties feed back to affect not only heart mechanics but also electrical conduction, reflex hemodynamic compensations, and the ongoing process of scar formation itself. In this article, we outline the scar formation process following a myocardial infarction, discuss interpretation of standard measures of heart function in the setting of a healing infarct, then present implications of infarct scar geometry and structure for both mechanical and electrical function of the heart and summarize experiences to date with therapeutic interventions that aim to modify scar geometry and structure. One important conclusion that emerges from the studies reviewed here is that computational modeling is an essential tool for integrating the wealth of information required to understand this complex system and predict the impact of novel therapies on scar healing, heart function, and remodeling following myocardial infarction.

  18. Dental implications in oral cancer patients. (United States)

    Escoda-Francolí, Jaume; Rodríguez-Rodríguez, Araceli; Pérez-García, Silvia; Gargallo-Albiol, Jordi; Gay-Escoda, Cosme


    A study is made of the dental implications of oral cancer, with a view to avoiding the complications that appear once oncological treatment is started. The study comprised a total of 22 patients diagnosed with oral cancer according to clinical and histological criteria in the Service of Maxillofacial Surgery (Dental Clinic of the University of Barcelona, Spain) during the period 1996-2005, and posteriorly treated in different hospital centers in Barcelona. Of the 22 patients diagnosed with oral cancer in our Service, the present study finally analyzed the 12 subjects who reported for the dental controls. As regards the remaining 10 patients, 5 had died and 5 could not be located; these subjects were thus excluded from the analysis. All of the smokers had abandoned the habit. The most common tumor location was the lateral margin of the tongue. None of the patients visited the dentist regularly before the diagnosis of oral cancer. T1N0M0 was the most common tumor stage. Surgery was carried out in 50% of the cases, while 8.4% of the patients received radiotherapy and 41.6% underwent surgery with postoperative radiotherapy. In turn, 66.6% of the patients reported treatment sequelae such as dysgeusia, xerostomia or speech difficulties, and one patient suffered osteoradionecrosis. Forty-one percent of the patients did not undergo regular dental controls after cancer treatment. As regards oral and dental health, 16.6% presented caries, and 50% had active periodontal disease. Protocols are available for preventing the complications of oral cancer treatment, and thus for improving patient quality of life. However, important shortcomings in the application of such protocols on the part of the public health authorities make it difficult to reach these objectives.

  3. Implications of Dual Practice among Health Workers: A Systematic Review. (United States)

    Moghri, Javad; Rashidian, Arash; Arab, Mohammad; Akbari Sari, Ali


    Mixed health care systems to work simultaneously on both public and private facilities, is common today. This phenomenon referred to as dual practice (DP), has potential implications for access, quality, cost and equity of health services. This paper aimed to review systematically studies that assess the implications of DP among health workers. MEDLINE, EMBASE, and The Cochrane library were searched for obtaining published literature between Feb 1990 and May 2014. Google and Google Scholars, organizational websites, and reference lists of relevant papers searched to get grey literature. Only studies concentrated on consequences and impacts of DP among health professionals and conducted using "randomized controlled trials", "non-randomized controlled trials", "controlled before and after studies", or "interrupted time series" were eligible for inclusion. From 3242 records, we focused on 19 studies, which aimed to assess effects and impacts of dual practice. After that, the current understanding of DP positive and negative implications was categorized and discussed based on two perspectives. There has been a propensity to over-reliance on theoretical methods in predicting the implications of this phenomenon. Almost all of the mentioned implications are based on theoretical predictions undermined in the broader literature. Furthermore, assessing the current literature showed positive and negative impacts of DP on different parts of the health system and various dimensions of service delivery. These implications are contexted specific and may vary from system to system.

  4. Implications of Water Development for Food Security (United States)

    Cai, X.; Rosegrant, M. W.


    Water development for agriculture-the major water user worldwide-is one of the most critical factors for food security in many regions of the world. The role of water withdrawals in irrigated agriculture and food security has been receiving substantial attention in recent years. This paper will address key questions regarding implications of water development for food security at both regional and global scale, including what is the current status of water availability for agriculture? How will water availability and water demand evolve over the next three decades, taking into account availability and variability in water resources, the water supply infrastructure, and irrigation and nonagricultural water demands? What is the role of irrigation in food production now and in the future? What risk will be put on regional and global food production, demand and trade if municipal and industrial water demand is high, environmental water requirement is increasing, or groundwater overdraft is phased off? What is the contribution of infrastructure investment in enhancing irrigation water supply capacity, improving water use efficiency, and increasing rainfall harvesting particularly in arid and semi-arid regions and countries? These questions are explored through a global modeling framework, IMPACT-Water, developed in the International Food Policy Research Institute. In general, the results show that, under plausible assumptions on developments in irrigation and water investment, the rapid growth in water demand, particularly for domestic and industrial purposes, coupled with the a continued slowdown in investments, could be a serious threat to future growth in food production, causing negative impacts on low-income developing countries and the poor consumers in these countries. Food production, demand and trade and food prices will be increasingly affected by declining water availibility for irrigation. Developing countries, especially those with arid climates, poor

  5. GEMAS - Soil geochemistry and health implications (United States)

    Ernstsen, Vibeke; Ladenberger, Anna; Wragg, Joanna; Gulan, Aleksandra


    The GEMAS Project resulted in a large coherent data set displaying baseline levels of elements in agricultural and grazing land soil, which has a wide variety of applications. Medical geology is an emerging new discipline providing a link between geoscience and medicine by interpreting natural geological factors in relation to human and animal health and their geographical distribution. Medical geology shows not only problems related to harmful health effects of natural geological materials and processes, but also deals with their beneficial aspects. Since the GEMAS project demonstrates the importance of geological factors in geochemical patterns in European soil, this data set can be used in improving our understanding of how the geological processes may affect human health in Europe. The main potential health problems are related to deficiency of nutrients in soil and toxic effects of potentially harmful elements. Deficiency in macro- (e.g., K, Fe, Mg, P) and micro-nutrients (e.g., Se, Zn, Cl) can be responsible for a reduction in crop productivity and certain health issues for livestock and humans. On the other hand, bioavailability of crucial elements depends on soil parameters, e.g., pH; namely, low pH in soil (in northern Europe) makes more micronutrients bioavailable, with the exception of Mo, P and Ca. Rocks underlying the soil layer have a major impact on soil composition, and soil parent material can be a main source of toxic metals, for instance, soil developed on black shale (e.g., Oslo region) shows potentially toxic levels of metals, such as As, Cd, U, Zn and Pb. High content of organic matter is another factor amplifying the toxic levels of metals in soil. Several important topics with health implications can be then addressed using the GEMAS data set, namely, soil properties and element bioavailability, arsenic toxicity, selenium deficiency, potential health effects of liming, uranium in European soil, influence of recent and historical volcanic

  6. Implications of Fast Reactor Transuranic Conversion Ratio

    Energy Technology Data Exchange (ETDEWEB)

    Steven J. Piet; Edward A. Hoffman; Samuel E. Bays


    Theoretically, the transuranic conversion ratio (CR), i.e. the transuranic production divided by transuranic destruction, in a fast reactor can range from near zero to about 1.9, which is the average neutron yield from Pu239 minus 1. In practice, the possible range will be somewhat less. We have studied the implications of transuranic conversion ratio of 0.0 to 1.7 using the fresh and discharge fuel compositions calculated elsewhere. The corresponding fissile breeding ratio ranges from 0.2 to 1.6. The cases below CR=1 (“burners”) do not have blankets; the cases above CR=1 (“breeders”) have breeding blankets. The burnup was allowed to float while holding the maximum fluence to the cladding constant. We graph the fuel burnup and composition change. As a function of transuranic conversion ratio, we calculate and graph the heat, gamma, and neutron emission of fresh fuel; whether the material is “attractive” for direct weapon use using published criteria; the uranium utilization and rate of consumption of natural uranium; and the long-term radiotoxicity after fuel discharge. For context, other cases and analyses are included, primarily once-through light water reactor (LWR) uranium oxide fuel at 51 MWth-day/kg-iHM burnup (UOX-51). For CR<1, the heat, gamma, and neutron emission increase as material is recycled. The uranium utilization is at or below 1%, just as it is in thermal reactors as both types of reactors require continuing fissile support. For CR>1, heat, gamma, and neutron emission decrease with recycling. The uranium utilization exceeds 1%, especially as all the transuranic elements are recycled. exceeds 1%, especially as all the transuranic elements are recycled. At the system equilibrium, heat and gamma vary by somewhat over an order of magnitude as a function of CR. Isotopes that dominate heat and gamma emission are scattered throughout the actinide chain, so the modest impact of CR is unsurprising. Neutron emitters are preferentially found

    O'Tousa, David; Grahame, Nicholas


    may be alleviated through the use of high-drinking rodent lines. Additionally, satiety, one common mechanism of devaluing reinforcers, is not recommended for alcohol research because the psychoactive effects of alcohol depress response rates, mimicking devaluation effects. Overall, further research of habit formation and potentially related perseverative behaviors could be invaluable in discovering genetic variance, traits that correlate with persistent alcohol seeking, implicated neural structures and processes of alcohol use, and eventually novel pharmacological treatment for alcoholism.

  8. Magmatic gas scrubbing: Implications for volcano monitoring (United States)

    Symonds, R.B.; Gerlach, T.M.; Reed, M.H.


    Despite the abundance of SO2(g) in magmatic gases, precursory increases in magmatic SO2(g) are not always observed prior to volcanic eruption, probably because many terrestrial volcanoes contain abundant groundwater or surface water that scrubs magmatic gases until a dry pathway to the atmosphere is established. To better understand scrubbing and its implications for volcano monitoring, we model thermochemically the reaction of magmatic gases with water. First, we inject a 915??C magmatic gas from Merapi volcano into 25??C air-saturated water (ASW) over a wide range of gas/water mass ratios from 0.0002 to 100 and at a total pressure of 0.1 MPa. Then we model closed-system cooling of the magmatic gas, magmatic gas-ASW mixing at 5.0 MPa, runs with varied temperature and composition of the ASW, a case with a wide range of magmatic-gas compositions, and a reaction of a magmatic gas-ASW mixture with rock. The modeling predicts gas and water compositions, and, in one case, alteration assemblages for a wide range of scrubbing conditions; these results can be compared directly with samples from degassing volcanoes. The modeling suggests that CO2(g) is the main species to monitor when scrubbing exists; another candidate is H2S(g), but it can be affected by reactions with aqueous ferrous iron. In contrast, scrubbing by water will prevent significant SO2(g) and most HCl(g) emissions until dry pathways are established, except for moderate HCl(g) degassing from pH 100 t/d (tons per day) of SO2(g) in addition to CO2(g) and H2S(g) should be taken as a criterion of magma intrusion. Finally, the modeling suggests that the interpretation of gas-ratio data requires a case-by-case evaluation since ratio changes can often be produced by several mechanisms; nevertheless, several gas ratios may provide useful indices for monitoring the drying out of gas pathways.

  10. Gastrointestinal Motility Disorders and Their Clinical Implications in Cirrhosis

    Directory of Open Access Journals (Sweden)

    Eleni Theocharidou


    Full Text Available Gastrointestinal motility is impaired in a substantial proportion of patients with cirrhosis. Cirrhosis-related autonomic neuropathy, increased nitric oxide production, and gut hormonal changes have been implicated. Oesophageal dysmotility has been associated with increased frequency of abnormal gastro-oesophageal reflux. Impaired gastric emptying and accommodation may result in early satiety and may have an impact on the nutritional status of these patients. Small intestinal dysmotility might be implicated in small intestinal bacterial overgrowth and increased bacterial translocation. The latter has been implicated in the pathophysiology of hepatic encephalopathy and spontaneous bacterial peritonitis. Enhanced colonic motility is usually associated with the use of lactulose. Pharmacological interventions aiming to alter gastrointestinal motility in cirrhosis could potentially have a beneficial effect reducing the risk of hepatic decompensation and improving prognosis.

  12. The CH/π hydrogen bond: Implication in chemistry (United States)

    Nishio, M.


    The CH/π hydrogen bond is the weakest extreme of hydrogen bonds that occurs between a soft acid CH and a soft base π-system. Implication in chemistry of the CH/π hydrogen bond includes issues of conformation, crystal packing, and specificity in host/guest complexes. The result obtained by analyzing the Cambridge Structural Database is reviewed. The peculiar axial preference of isopropyl group in α-phellandrene and folded conformation of levopimaric acid have been explained in terms of the CH/π hydrogen bond, by high-level ab initio MO calculations. Implication of the CH/π hydrogen bond in structural biology is also discussed, briefly.

    . We undertook these challenges by using an established clinical paradigm, the estrogen hypothesis of schizophrenia, as the criterion to select candidates among the numerous genes experimentally implicated in schizophrenia. Bioinformatic tools were used to build and priorities the signaling networks...... implicated by the candidate genes resulting from the estrogen selection. We identified ten candidate genes using this approach that are all active in glucose metabolism and particularly in the glycolysis. Thus, we tested the hypothesis that variants of the glycolytic genes are associated with schizophrenia...

  14. The rationalisation movement in perspective and some ergonomic implications. (United States)

    Björkman, T


    The paper gives an overview of the Rationalisation Movement from Taylor to the most recent organisation models such as 'Business Process Reengineering'. Special emphasis is put on the estimated implications of the different rationalisation strategies in terms of ergonomics/work physiology. In addition, basic terms and concepts are defined. According to the author, Taylorism, Fordism and Lean Production seem to offer an insufficient potential for good ergonomics. However, more recent organisational models such as 'Time Based Management' and 'Business Process Reengineering', may appear more promising but unfortunately almost no research has been conducted to describe the ergonomics implications of these models.

  15. Placebo effects: from the neurobiological paradigm to translational implications. (United States)

    Benedetti, Fabrizio


    Today we are witnessing a new science of placebo, a complex discipline that encompasses several experimental approaches and translational implications. Modern neurobiological tools have been used to answer important questions in placebo research, such as the top-down modulation of sensory and motor systems as well as the influence of cognition, emotions, and learning on symptoms, diseases, and responses to treatments. What we have learned is that there is not one single placebo effect, but many. This review highlights the translational implications of this new knowledge, ranging from clinical trial design to medical practice to social and ethical issues. Copyright © 2014 Elsevier Inc.
