  2. De-icers derived from corn steep water.

    Yang, Byung Yun; Montgomery, Rex

    2003-12-01

    Corn steep water (CSW) and other byproducts derived from fermentations and sugar productions are presently forming the base of compositions for de-icing and anti-icing materials. Since the de-icing and anti-icing values are in part a colligative property, increase in the molar concentration of ionic species has been frequently necessary to decrease further the freezing point of this byproducts stream. In the present study this has been achieved by the generation of biodegradable organic acid salts in situ, without the use of chloride or other inorganic salts, by the alkaline degradation of reducing sugars added to corn steep water, which alone is not an efficient de-icer. Reducing sugars, such as glucose, react with alkali metal hydroxides to produce principally hydroxy carboxylic acids that react with the alkali metal hydroxide to form a mixture of organic acid salts. The ionic strength of the resulting solution is increased since each sugar molecule produces nearly two acid molecules upon degradation. The ionic strength necessary to achieve the desired freezing point depression is determined by the amount and concentration of the alkali metal hydroxide used, with the necessary counter anions being derived from the degradation of the reducing sugar. The amount of the sugar used is that required to result in a near to neutral final solution. The well-known anti-corrosive property of CSW is used in the de-icer preparations, either by conducting the alkaline degradation of the sugar in this medium, or by using water for the degradation of the sugar followed by dilution of the resulting solution with CSW to adjust the viscosity of the final solution to meet the requirements for spraying. The monovalent metal hydroxides are more efficient in producing de-icer solutions than the divalent metal hydroxides.

  3. Aircraft de-icer: Recycling can cut carbon emissions in half

    International Nuclear Information System (INIS)

    Johnson, Eric P.

    2012-01-01

    Flight-safety regulations in most countries require aircraft to be ice-free upon takeoff. In icy weather, this means that the aircraft usually must be de-iced (existing ice is removed) and sometimes anti-iced (to protect against ice-reformation). For both processes, aircraft typically are sprayed with an ‘antifreeze’ solution, consisting mainly of glycol diluted with water. This de/anti-icing creates an impact on the environment, of which environmental regulators have grown increasingly conscious. The US Environmental Protection Agency (EPA), for example, recently introduced stricter rules that require airports above minimum size to collect de-icing effluents and send them to wastewater treatment. De-icer collection and treatment is already done at most major airports, but a few have gone one step further: rather than putting the effluent to wastewater, they recycle it. This study examines the carbon savings that can be achieved by recycling de-icer. There are two key findings. One, recycling, as opposed to not recycling, cuts the footprint of aircraft de-icing by 40–50% — and even more, in regions where electricity-generation is cleaner. Two, recycling petrochemical-based de-icer generates a 15–30% lower footprint than using ‘bio’ de-icer without recycling. - Highlights: ► Carbon footprint of aircraft de-icing can be measured. ► Recycling aircraft de-icer cuts the footprint of aircraft de-icing by 40–50%. ► Recycling ‘fossil’ de-icer is lower carbon than not recycling ‘bio’ de-icer.

  5. Depression, Stressful Life Events, and the Impact of Variation in the Serotonin Transporter: Findings from the National Longitudinal Study of Adolescent to Adult Health (Add Health.

    Directory of Open Access Journals (Sweden)

    Brett C Haberstick

    Full Text Available The low transcriptionally efficient short-allele of the 5HTTLPR serotonin transporter polymorphism has been implicated to moderate the relationship between the experience of stressful life events (SLEs and depression. Despite numerous attempts at replicating this observation, results remain inconclusive.We examined this relationship in young-adult Non-Hispanic white males and females between the ages of 22 and 26 (n = 4724 participating in the National Longitudinal Study of Adolescent to Adult Health (Add Health with follow-up information every six years since 1995.Linear and logistic regression models, corrected for multiple testing, indicated that carriers of one or more of the S-alleles were more sensitive to stress than those with two L-alleles and at a higher risk for depression. This relationship behaved in a dose-response manner such that the risk for depression was greatest among those who reported experiencing higher numbers of SLEs. In post-hoc analyses we were not able to replicate an interaction effect for suicide ideation but did find suggestive evidence that the effects of SLEs and 5HTTLPR on suicide ideation differed for males and females. There were no effects of childhood maltreatment.Our results provide partial support for the original hypothesis that 5-HTTLPR genotype interacts with the experience of stressful life events in the etiology of depression during young adulthood. However, even with this large sample, and a carefully constructed a priori analysis plan, the results were still not definitive. For the purposes of replication, characterizing the 5HTTLPR in other large data sets with extensive environmental and depression measures is needed.

    This paper summarizes part of the research work carried out in the Add Control project, which proposes an extension of the wastewater treatment plant (WWTP) models and modelling architectures used in traditional WWTP simulation tools, addressing, in addition to the classical mass transformations (transport, physico-chemical phenomena, biological reactions), all the instrumentation, actuation and automation & control components (sensors, actuators, controllers), considering their real behaviour (signal delays, noise, failures and power consumption of actuators). Its ultimate objective is to allow a rapid transition from the simulation of the control strategy to its implementation at full-scale plants. Thus, this paper presents the application of the Add Control simulation platform for the design and implementation of new control strategies at the WWTP of Mekolalde.

    Blom, J D; Kooij, J J S

    2012-01-01

    Two patients with a psychotic disorder who also met the diagnostic criteria for attention deficit hyperactivity disorder ADHD were treated with antipsychotics and methylphenidate. The first patient remained stable for many years with this combination treatment, whereas the second became psychotic several months after he had increased the dose of methylphenidate and had started to use cocaine. In the light of these two case studies, we have reviewed the literature on ADD psychosis, and we formulate recommendations regarding the specialised treatment needed for this uncommon disorder.

  16. Using Joint Interviews to Add Analytic Value.

    Science.gov (United States)

    Polak, Louisa; Green, Judith

    2016-10-01

    Joint interviewing has been frequently used in health research, and is the subject of a growing methodological literature. We review this literature, and build on it by drawing on a case study of how people make decisions about taking statins. This highlights two ways in which a dyadic approach to joint interviewing can add analytic value compared with individual interviewing. First, the analysis of interaction within joint interviews can help to explicate tacit knowledge and to illuminate the range of often hard-to-access resources that are drawn upon in making decisions. Second, joint interviews mitigate some of the weaknesses of interviewing as a method for studying practices; we offer a cautious defense of the often-tacit assumption that the "naturalness" of joint interviews strengthens their credibility as the basis for analytic inferences. We suggest that joint interviews are a particularly appropriate method for studying complex shared practices such as making health decisions. © The Author(s) 2015.

  17. Independents add gas reserves, forego romance

    Energy Technology Data Exchange (ETDEWEB)

    Gill, D.

    1981-08-01

    Incentive pricing for low-permeability reservoirs and tax advantages for drilling them are 2 big reasons why more independents may start making a special effort to add gas reserves to their inventories. If so, it will be a change from past practices, which saw independents build up big gas positions by circumstance rather than by intention. There are always major refiners ready and willing to buy whole crude oil reservoirs from small producers, but purchasers willing to take gas fields in a single investment are few and far between. Lower-than-normal return on equity during the first 20 years, plus the heavy front-end cost of a frac necessary to produce the tight gas might dissuade independents from drilling tight gas sands, but those liabilities are offset by the higher price tight gas gets and the peculiar tax advantages of exploring for it that make a nice fit with the small operator's way of doing business.

  19. Seasonal Drivers of Dissolved Metal Transport During Infiltration of Road Runoff in an Urban Roadside Environment

    Science.gov (United States)

    Mullins, A.; Bain, D.

    2017-12-01

    Infiltration-based green infrastructure (GI) is being increasingly applied in urban areas, systems characterized by substantial legacy contamination and complicated hydrology. However, it is not clear how the application of green infrastructure changes the geochemistry of urban roadside environments. Most current research on GI focuses on small sets of chemical parameters (e.g. road salt, nitrogen and phosphorous species) over relatively short time periods, limiting comprehensive understanding of geochemical function. This work measures changes in groundwater infiltration rate and dissolved metal concentrations in two infiltration trenches in Pittsburgh, PA to evaluate function and measure dissolved metal transport from the system over time. Two distinct geochemical regimes seem to be driven by seasonality: road de-icer exchange and microbial driven summer reducing conditions. Interactions between these geochemical regimes and variability in infiltration rate control the flux of different metals, varying with metal chemistry. These findings suggest the adoption of infiltration based green infrastructure will likely create complicated patterns of legacy contamination transport to downstream receptors.

    Teeka, Chat; Jalil, Muhammad Arif; Yupapin, Preecha P; Ali, Jalil

    2010-12-01

    We propose a novel system of the dynamic optical tweezers generated by a dark soliton in the fiber optic loop. A dark soliton known as an optical tweezer is amplified and tuned within the microring resonator system. The required tunable tweezers with different widths and powers can be controlled. The analysis of dark-bright soliton conversion using a dark soliton pulse propagating within a microring resonator system is analyzed. The dynamic behaviors of soliton conversion in add/drop filter is also analyzed. The control dark soliton is input into the system via the add port of the add/drop filter. The dynamic behavior of the dark-bright soliton conversion is observed. The required stable signal is obtained via a drop and throughput ports of the add/drop filter with some suitable parameters. In application, the trapped light/atom and transportation can be realized by using the proposed system.

    1989-01-01

    One-dimensional infrared speckle scans of Ross 614 AB were recorded at a wavelength of 2.2 microns, and the three bins corresponding to the three best seeing conditions were further processed by applying a shift-and-add algorithm to the set of images contained within each bin, generating three shift-and-add images with differing shift-and-add point-spread functions. A zero-and-add technique was used to deconvolve the three shift-and-add images in order to obtain parameters corresponding to the separation and the brightness ratio of a two-component model of Ross 614 Ab. Least-squares analysis results reveal a separation of 1.04 arcsec and a brightness ratio of 4.3 for the binary system at this wavelength. 31 refs

    2017-12-09

    Increasing evidence shows that immune-mediated mechanisms may contribute to the pathogenesis of central nervous system disorders including cerebellar ataxias, as indicated by the aberrant production of neuronal surface antibodies. We previously reported a patient with cerebellar ataxia associated with production of a new anti-neuronal antibody, anti-seizure-related 6 homolog like 2 (Sez6l2). Sez6l2 is a type 1 membrane protein that is highly expressed in the hippocampus and cerebellar cortex and mice lacking Sez6l2 protein family members develop ataxia. Here we used a proteomics-based approach to show that serum derived from this patient recognizes the extracellular domain of Sez6l2 and that Sez6l2 protein binds to both adducin (ADD) and glutamate receptor 1 (GluR1). Our results indicate that Sez6l2 is one of the auxiliary subunits of the AMPA receptor and acts as a scaffolding protein to link GluR1 to ADD. Furthermore, Sez6l2 overexpression upregulates ADD phosphorylation, whereas siRNA-mediated downregulation of Sez612 prevents ADD phosphorylation, suggesting that Sez6l2 modulates AMPA-ADD signal transduction.

    Despite adequate treatment with antipsychotics, a substantial number of patients with schizophrenia demonstrate only suboptimal clinical outcome. To overcome this challenge, various psychopharmacological combination strategies have been used, including antidepressants added to antipsychotics. To analyze the efficacy of add-on antidepressants for the treatment of negative, positive, cognitive, depressive, and antipsychotic-induced extrapyramidal symptoms in schizophrenia, published randomized controlled trials assessing the efficacy of adjunctive antidepressants in schizophrenia were reviewed using the following parameters: baseline clinical characteristics and number of patients, their on-going antipsychotic treatment, dosage of the add-on antidepressants, duration of the trial, efficacy measures, and outcomes. There were 36 randomized controlled trials reported in 41 journal publications (n=1582). The antidepressants used were the selective serotonin reuptake inhibitors, duloxetine, imipramine, mianserin, mirtazapine, nefazodone, reboxetin, trazodone, and bupropion. Mirtazapine and mianserin showed somewhat consistent efficacy for negative symptoms and both seemed to enhance neurocognition. Trazodone and nefazodone appeared to improve the antipsychotics-induced extrapyramidal symptoms. Imipramine and duloxetine tended to improve depressive symptoms. No clear evidence supporting selective serotonin reuptake inhibitors' efficacy on any clinical domain of schizophrenia was found. Add-on antidepressants did not worsen psychosis. Despite a substantial number of randomized controlled trials, the overall efficacy of add-on antidepressants in schizophrenia remains uncertain mainly due to methodological issues. Some differences in efficacy on several schizophrenia domains seem, however, to exist and to vary by the antidepressant subgroups--plausibly due to differences in the mechanisms of action. Antidepressants may not worsen the course of psychosis. Better designed

    1985-05-01

    A new method for image restoration based on the shift-and-add (SAA) algorithm is presented, the main advantages of which appear to be speed and simplicity. The SAA pattern produced by an object is given by the object correlated by a nonlinear replica of itself whose intensity distribution is strongly weighted toward the brighter pixels. A method of successive substitutions analogous to Fienup's algorithm can then be used to decorrelate the SAA pattern and recover the object. The method is applied to the case of the extended chromosphere of Betelgeuse.

    Sensory feedback systems have been of great interest in upper-limb prosthetics. Despite tremendous research, there are no commercial modality-matched feedback systems. This article aims to introduce the first detachable and feedback add-on option that can be attached to in-use prostheses. A sensory feedback system was tested on a below-elbow myoelectric prosthesis. The aim was to have the amputee grasp fragile objects without crushing while other accidental feedback sources were blocked. A total of 8 successful trials (out of 10) showed that sensory feedback system decreased the amputee's visual dependency by improving awareness of his prosthesis. Sensory feedback system can be used either as post-fabrication (prosthetic add-on option) or para-fabrication (incorporated into prosthetic design). The use of these direct feedback systems can be explored with a current prosthesis before ordering new high-tech prosthesis. Clinical relevance This technical note introduces the first attach/detach-able sensory feedback system that can simply be added to in-use (myo)electric prosthesis, with no obligation to change prosthesis design or components.

    Patient lists are project-specific sets of patients that can be queried in integrated data repositories (IDR's). By allowing a set of patients to be an addition to the qualifying conditions of a query, returned results will refer to, and only to, that set of patients. We report a variety of use cases for such lists, including: restricting retrospective chart review to a defined set of patients; following a set of patients for practice management purposes; distributing "honest-brokered" (deidentified) data; adding phenotypes to biosamples; and enhancing the content of study or registry data. Among the capabilities needed to implement patient lists in an IDR are: capture of patient identifiers from a query and feedback of these into the IDR; the existence of a permanent internal identifier in the IDR that is mappable to external identifiers; the ability to add queryable attributes to the IDR; the ability to merge data from multiple queries; and suitable control over user access and de-identification of results. We implemented patient lists in a custom IDR of our own design. We reviewed capabilities of other published IDRs for focusing on sets of patients. The widely used i2b2 IDR platform has various ways to address patient sets, and it could be modified to add the low-overhead version of patient lists that we describe. Copyright © 2014 Elsevier Inc.

    2018-01-22

    Epilepsy is a common neurologic disorder, affecting approximately 50 million people worldwide; nearly a third of these people have epilepsy that is not well controlled by a single antiepileptic drug (AED) and they usually require treatment with a combination of two or more AEDs. In recent years, many newer AEDs have been investigated as add-on therapy for focal epilepsy; losigamone is one of these drugs and is the focus of this systematic review. This is an update of a Cochrane review first published in 2012 (Cochrane Database of Systematic Reviews 2012, Issue 6) and updated in 2015. To investigate the efficacy and safety of losigamone when used as an add-on therapy for focal epilepsy. For the latest update on 9 February 2017, we searched the Cochrane Epilepsy Specialized Register, CENTRAL and MEDLINE . We searched trials registers and contacted the manufacturer of losigamone and authors of included studies for additional information. We did not impose any language restrictions. Randomized controlled, add-on trials comparing losigamone with placebo for focal epilepsy. Two review authors independently assessed trial quality and extracted data. The primary outcomes were 50% or greater reduction in seizure frequency and seizure freedom; the secondary outcomes were treatment withdrawal and adverse events. Results are presented as risk ratios (RRs) with 95% confidence intervals (CIs) or 99% CIs (for the individual listed adverse events to make an allowance for multiple testing). Two trials involving a total of 467 participants, aged over 18 years, were eligible for inclusion. Both trials assessed losigamone 1200 mg/day or 1500 mg/day as an add-on therapy for focal epilepsy. We assessed one trial as being of good methodological quality while the other was of uncertain quality. For the efficacy outcomes, results did show that participants taking losigamone were significantly more likely to achieve a 50% or greater reduction in seizure frequency (RR 1.76, 95% CI 1.14 to 2

  13. Symbolic BDD and ADD Algorithms for Energy Games

    2016-11-01

    Full Text Available Energy games, which model quantitative consumption of a limited resource, e.g., time or energy, play a central role in quantitative models for reactive systems. Reactive synthesis constructs a controller which satisfies a given specification, if one exists. For energy games a synthesized controller ensures to satisfy not only the safety constraints of the specification but also the quantitative constraints expressed in the energy game. A symbolic algorithm for energy games, recently presented by Chatterjee et al., is symbolic in its representation of quantitative values but concrete in the representation of game states and transitions. In this paper we present an algorithm that is symbolic both in the quantitative values and in the underlying game representation. We have implemented our algorithm using two different symbolic representations for reactive games, Binary Decision Diagrams (BDD and Algebraic Decision Diagrams (ADD. We investigate the commonalities and differences of the two implementations and compare their running times on specifications of energy games.

    2015-03-01

    The application of ultrasound in an Atomic Force Microscope (AFM) gives access to subsurface information. However, no commercially AFM exists that is equipped with this technique. The main problems are the electronic crosstalk in the AFM setup and the insufficiently strong excitation of the cantilever at ultrasonic (MHz) frequencies. In this paper, we describe the development of an add-on that provides a solution to these problems by using a special piezo element with a lowest resonance frequency of 2.5 MHz and by separating the electronic connection for this high frequency piezo element from all other connections. In this sense, we support researches with the possibility to perform subsurface measurements with their existing AFMs and hopefully pave also the way for the development of a commercial AFM that is capable of imaging subsurface features with nanometer resolution.

  19. Lixisenatide as add-on therapy to basal insulin

    Full Text Available Dominique Xavier Brown, Emma Louise Butler, Marc Evans Diabetes Department, University Hospital Llandough, Cardiff, UK Abstract: Many patients with type 2 diabetes mellitus do not achieve target glycosylated hemoglobin A1c levels despite optimally titrated basal insulin and satisfactory fasting plasma glucose levels. Current evidence suggests that HbA1c levels are dictated by both basal glucose and postprandial glucose levels. This has led to a consensus that postprandial glucose excursions contribute to poor glycemic control in these patients. Lixisenatide is a once-daily, prandial glucagon-like peptide 1 (GLP-1 receptor agonist with a four-fold affinity for the GLP-1 receptor compared with native GLP-1. Importantly, lixisenatide causes a significant delay in gastric emptying time, an important determinant of the once-daily dosing regimen. An exendin-4 mimetic with six lysine residues removed at the C-terminal, lixisenatide has pronounced postprandial glucose-lowering effects, making it a novel incretin agent for use in combination with optimally titrated basal insulin. Lixisenatide exerts profound effects on postprandial glucose through established mechanisms of glucose-dependent insulin secretion and glucagon suppression in combination with delayed gastric emptying. This review discusses the likely place that lixisenatide will occupy in clinical practice, given its profound effects on postprandial glucose and potential to reduce glycemic variability. Keywords: lixisenatide, add-on therapy, insulin, GLP-1 receptor agonist, postprandial glucose, pharmacodynamics

    Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change. Aquaculture can potentially enhance resilience through improved resource use efficiencies and increased diversification of farmed species, locales of production, and feeding strategies. However, aquaculture's reliance on terrestrial crops and wild fish for feeds, its dependence on freshwater and land for culture sites, and its broad array of environmental impacts diminishes its ability to add resilience. Feeds for livestock and farmed fish that are fed rely largely on the same crops, although the fraction destined for aquaculture is presently small (∼4%). As demand for high-value fed aquaculture products grows, competition for these crops will also rise, as will the demand for wild fish as feed inputs. Many of these crops and forage fish are also consumed directly by humans and provide essential nutrition for low-income households. Their rising use in aquafeeds has the potential to increase price levels and volatility, worsening food insecurity among the most vulnerable populations. Although the diversification of global food production systems that includes aquaculture offers promise for enhanced resilience, such promise will not be realized if government policies fail to provide adequate incentives for resource efficiency, equity, and environmental protection.

  1. Informatics in managed care: HIM adds value to data.

    Stratton, S D

    2001-09-01

    The third installment of the Journal of AHIMA's special series on managed care focuses on informatics--methods that add value to data, turning it into useful information. How do informatics and managed care fit together and what is HIM's role in this picture? The HIM professional's knowledge is critical to the health team responsible for the interpretation and use of statically valid information. For example, HIM professionals are well positioned in their understanding of the construct and application of coding classification systems (ICD-9-CM, CPT, etc.), and groupers (DRGs, APCs, ETGs, etc.). Their unique training positions them to understand the associated rules, principles, guidelines, and nuances associated with correct coding and grouping. And when codes or groupers change, HIM professionals work closely with the health team to ensure parity, validity and reliability of the appropriate data or data sets. Managed care organizations use value-added data, as you will see in this article, to evaluate contract pricing, develop contracts, evaluate existing services or detail benefit plans, process and in some instances pay claims, and report results to a number of interested parties. The previous article in this series ("Can You Manage Managed Care?" July/August 2001) focused on effective management of data, including data acquisition. This article takes us to the next level, where informatics creates value-added information, and discusses some important uses of this information within managed care. These articles build on two of the functional areas that form the HIM process within managed care organizations. Author Scott Stratton studied under the creators of DRGs and was involved in the development of their nursing home counterpart, RUGs. He also has worked with the creators of ETGs. As a result, he can present the perspective and context within which these systems were created and intended. and how they form the foundation for informatics as a functional area

  2. What a signature adds to the consent process.

    LENUS (Irish Health Repository)

    Neary, Peter

    2012-02-03

    BACKGROUND: "Consent is a process by which a patient is informed and becomes a participant in decisions regarding their medical management." It is argued, however, that providing a signature to a form adds little to the quality of this process. METHODS: Views regarding the consent ritual of nonselected patients undergoing endoscopy (cystoscopy or sigmoidoscopy) were prospectively studied together with those of the attending staff. Patient volunteers were randomly assigned to one of two groups and given verbal explanation before the procedure, either alone (group A) or with a request to sign a form in addition (group B). A standardized questionnaire regarding preferences then was applied. RESULTS: A total of 37 patients (22 men) were studied along with seven staff members. Most surveyed felt that signing a consent form helped to empower the patient (group A, 84%; group B, 83%; staff, 100%). Although the patients mainly believed that it functioned primarily to protect the hospital and doctor (group A, 89%; group B, 67%), only one patient (3% of total) felt that such a formality undermined the patient-doctor relationship. Most staff members favored signing a form (86%). The majority of patients either favored it (group A, 47%; group B, 78%) or expressed no strong preference (group A, 32%; group B, 11%). Interestingly, more women than men preferred signing (73 vs. 55%; p = 0.25), perhaps because more women believed that it functioned to preserve autonomy (93 vs. 77% of men). Age was no particular determinant of perspective. CONCLUSION: Although it may be viewed as primarily serving to protect the doctor and hospital, the formal process of signing written consent forms appeals to patients and staff.

    Physician requests for additional testing on an existing laboratory specimen (add-ons) are resource intensive and generally require a phone call to the laboratory. Verbal orders such as these have been noted to be associated with errors in accuracy. The aim of this study was to compare a novel computerized system for add-on requests to the prior verbal system. We compare the computerized add-on request system to the verbal system with respect to order completeness and workflow. We demonstrate that the computerized add-on system resulted in the complete in-laboratory documentation of the add-on request 100% of the time, compared to 58% with the verbal add-on system. In addition, we show that documentation of a verbal add-on request in the electronic medical record (EMR) occurred for 4% of requests, while in the computerized system EMR documentation occurred 100% of the time. We further demonstrate that the computerized add-on request process was well accepted by providers and did not significantly change the test mix of the add-on requests. In computerized physician order entry (CPOE) implementations, add-on order functionality should be considered so these orders are documented in the EMR.

  4. Embedding objects during 3D printing to add new functionalities.

    2016-07-01

    A novel method for integrating and embedding objects to add new functionalities during 3D printing based on fused deposition modeling (FDM) (also known as fused filament fabrication or molten polymer deposition) is presented. Unlike typical 3D printing, FDM-based 3D printing could allow objects to be integrated and embedded during 3D printing and the FDM-based 3D printed devices do not typically require any post-processing and finishing. Thus, various fluidic devices with integrated glass cover slips or polystyrene films with and without an embedded porous membrane, and optical devices with embedded Corning(®) Fibrance™ Light-Diffusing Fiber were 3D printed to demonstrate the versatility of the FDM-based 3D printing and embedding method. Fluid perfusion flow experiments with a blue colored food dye solution were used to visually confirm fluid flow and/or fluid perfusion through the embedded porous membrane in the 3D printed fluidic devices. Similar to typical 3D printed devices, FDM-based 3D printed devices are translucent at best unless post-polishing is performed and optical transparency is highly desirable in any fluidic devices; integrated glass cover slips or polystyrene films would provide a perfect optical transparent window for observation and visualization. In addition, they also provide a compatible flat smooth surface for biological or biomolecular applications. The 3D printed fluidic devices with an embedded porous membrane are applicable to biological or chemical applications such as continuous perfusion cell culture or biocatalytic synthesis but without the need for any post-device assembly and finishing. The 3D printed devices with embedded Corning(®) Fibrance™ Light-Diffusing Fiber would have applications in display, illumination, or optical applications. Furthermore, the FDM-based 3D printing and embedding method could also be utilized to print casting molds with an integrated glass bottom for polydimethylsiloxane (PDMS) device replication

  15. Radio Telescopes Will Add to Cassini-Huygens Discoveries

    2004-12-01

    When the European Space Agency's Huygens spacecraft makes its plunge into the atmosphere of Saturn's moon Titan on January 14, radio telescopes of the National Science Foundation's National Radio Astronomy Observatory (NRAO) will help international teams of scientists extract the maximum possible amount of irreplaceable information from an experiment unique in human history. Huygens is the 700-pound probe that has accompanied the larger Cassini spacecraft on a mission to thoroughly explore Saturn, its rings and its numerous moons. The Green Bank Telescope The Robert C. Byrd Green Bank Telescope CREDIT: NRAO/AUI/NSF (Click on image for GBT gallery) The Robert C. Byrd Green Bank Telescope (GBT) in West Virginia and eight of the ten telescopes of the continent-wide Very Long Baseline Array (VLBA), located at Pie Town and Los Alamos, NM, Fort Davis, TX, North Liberty, IA, Kitt Peak, AZ, Brewster, WA, Owens Valley, CA, and Mauna Kea, HI, will directly receive the faint signal from Huygens during its descent. Along with other radio telescopes in Australia, Japan, and China, the NRAO facilities will add significantly to the information about Titan and its atmosphere that will be gained from the Huygens mission. A European-led team will use the radio telescopes to make extremely precise measurements of the probe's position during its descent, while a U.S.-led team will concentrate on gathering measurements of the probe's descent speed and the direction of its motion. The radio-telescope measurements will provide data vital to gaining a full understanding of the winds that Huygens encounters in Titan's atmosphere. Currently, scientists know little about Titan's winds. Data from the Voyager I spacecraft's 1980 flyby indicated that east-west winds may reach 225 mph or more. North-south winds and possible vertical winds, while probably much weaker, may still be significant. There are competing theoretical models of Titan's winds, and the overall picture is best summarized as

  16. The Influence of Socioeconomic Status on Psychological Distress in Canadian Adults With ADD/ADHD.

    Pond, Emily; Fowler, Ken; Hesson, Jacqueline

    2016-06-10

    The primary purpose of this study was to examine the relationship between socioeconomic status (SES) and psychological distress in individuals self-reporting a diagnosis of attention deficit disorder (ADD)/ADHD. This correlational study encompasses cross-sectional data from 488 male and female adults (20-64 years) who reported that they have been diagnosed with ADD/ADHD. Psychological distress was measured with the Kessler Psychological Distress Scale (K10). Adults with ADD/ADHD and high incomes have significantly lower K10 scores than Canadians with ADD/ADHD and low incomes. Income, but not education, was significant in predicting psychological distress among the sample. Canadian adults with ADD/ADHD have an increased risk for developing psychological distress and comorbid psychiatric disorders. The findings suggest that negative outcomes associated with ADD/ADHD are not necessarily pervasive. High income may serve as a protective factor for psychological distress among adults with ADD/ADHD. © The Author(s) 2016.

    Martinson, Jennifer; Tang, Hsin-Yi Jean

    2010-08-01

    This study explores how family nurse practitioners (FNPs) in the state of Washington view adulthood attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD) and how these views affect the pharmacotherapy FNPs employ. A confidential survey containing 30 questions was mailed to self-selected FNPs who practice in the state of Washington (N= 126). Descriptive and Kendall's rank correlations coefficient statistical methods were used for data analysis. The majority of respondents do not hold negative views toward adults with ADD/ADHD and are aware that their personal views may affect how they treat the disorder. Most of the respondents agreed that given the likelihood of co-morbidity of adult ADD/ADHD, it can be a challenge to diagnose the disorder. The predominant prescribed medications for adult ADD/ADHD are consistent with current pediatric guidelines, with the exception of buproprion, which was identified by 40% of the respondents as either their primary or secondary drug of choice for treating adult ADD/ADHD. Research effort needs to focus on the efficacy of buproprion for treating ADD/ADHD in adults. Moreover, exploration of the effectiveness of current pediatric guidelines to treat ADD/ADHD in adults must be assessed.

    2014-01-01

    This document summarizes the content of a 402 p. study published by CEDIGAZ, the International Center for Natural Gas Information. According to this study, LNG as a fuel will capture a significant market share in the transport sector by 2035. The greatest potential is seen in road transport, were annual demand is projected to reach 96 million tons per year (mtpa) in CEDIGAZ' base scenario while demand in the marine sector could grow to an estimated 77 mtpa. The rail sector could add another 6 mtpa to global demand. However, the development of LNG as a transport fuel faces a number of challenges, and will have to go hand in hand with the development of fueling infrastructure

    The aim of this study was to estimate the prevalence and probabilities of comorbidities between self-reported ADD/ADHD and smoking, alcohol binge drinking, and substance use disorders (SUDs) from a national Canadian sample. Data were taken from the Public Use Microdata File of the 2012 Canadian Community Health Survey-Mental Health (N = 17 311). The prevalence of (a) smoking, (b) alcohol binge drinking, and (c) SUDs was estimated among those with an ADD/ADHD diagnosis versus those without an ADD/ADHD diagnosis. After controlling for potential socioeconomic and mental health covariates, self-reported ADD/ADHD acted as a significant predictor for group membership in the heaviest smoking, heaviest drinking, and heaviest drug usage categories. Individuals self-reporting a diagnosis of ADD/ADHD were found to have a significantly higher likelihood of engaging in smoking and alcohol binge drinking, and were more likely to meet criteria for SUDs than individuals not reporting an ADD/ADHD diagnosis. © The Author(s) 2016.

    Although most procedures in the endoscopy clinic are elective, emergency add-on cases in hospital-based endoscopy clinics are common, frequently consuming a great deal of time and resources relative to elective endoscopy procedures. To determine which specific factors correlate with the high volume of add-on emergency cases in a tertiary care, hospital-based endoscopy unit. A retrospective chart review of all gastrointestinal add-on, and electively booked cases of esophagastroduodenoscopy (EGD), colonoscopy(C) and flexible sigmoidoscopy(FS)procedures from September 2006 to May 2007, was conducted. The day of the week, month, type of procedure and physician were recorded. Emergency add-on procedures performed during the weekends were not assessed. These cases were then compared with elective cases during a similar time frame to determine differences in the aspects of add-on cases versus those that were elective. Seven hundred twenty-one add-on cases were reviewed (mean patient age 57.4 years; 46% women) and compared with 736 elective cases (mean age 56 years; 49% women; P not significant). Of the add-on cases, 377 (52%) were EGD, 216 C (30%) and 105 (15%) were FS, with 23 combined procedures (3.2%) versus 202 (27%) EGD, 442 (60%) C and 74 (10%) FS in the elective group. Add-on cases were more likely to be EGDs than elective cases (OR 2.7; 95% CI 1.8 to 4.3; Padd-on cases on Mondays (OR 1.7; 95% CI 1.0 to 2.28; P>0.03). Conversely, there were significantly fewer procedures added on Fridays (OR 0.31; 95% CI 0.16 to 0.57; P=0.0001). There were statistically fewer add-on cases in September compared with the other months that were evaluated (OR 0.31; 95% CI 0.11 to 0.78; P=0.0006). With the present system of performing only emergency cases on the weekend, Monday tends to have more add-on cases. Consistent with the fact that upper gastrointestinal bleeding is the most common emergency condition, EGD is more common in add-on cases than with elective cases. Although

The genetic variant of the alpha-adducin gene (ADD1) has been described as a risk factor for EH, but with controversial results.The objective of this study was to evaluate the association of ADD1 (Gly460Trp) gene polymorphism with the EH risk in a population from Madeira Island.A case-control study with 1614 individuals of Caucasian origin was performed, including 817 individuals with EH and 797 controls. Cases and controls were matched for sex and age, by frequency-matching method. All participants collected blood for biochemical and genotypic analysis for the Gly460Trp polymorphism. We further investigated which variables were independently associated to EH, and, consequently, analyzed their interactions.In our study, we found a significant association between the ADD1 gene polymorphism and EH (odds ratio 2.484, P = .01). This association remained statistically significant after the multivariate analysis (odds ratio 2.548, P = .02).The ADD1 Gly460Trp gene polymorphism is significantly and independently associated with EH risk in our population. The knowledge of genetic polymorphisms associated with EH is of paramount importance because it leads to a better understanding of the etiology and pathophysiology of this pathology.

    Full Text Available Abstract Background In the current era of scientific research, efficient communication of information is paramount. As such, the nature of scholarly and scientific communication is changing; cyberinfrastructure is now absolutely necessary and new media are allowing information and knowledge to be more interactive and immediate. One approach to making knowledge more accessible is the addition of machine-readable semantic data to scholarly articles. Results The Word add-in presented here will assist authors in this effort by automatically recognizing and highlighting words or phrases that are likely information-rich, allowing authors to associate semantic data with those words or phrases, and to embed that data in the document as XML. The add-in and source code are publicly available at http://www.codeplex.com/UCSDBioLit. Conclusions The Word add-in for ontology term recognition makes it possible for an author to add semantic data to a document as it is being written and it encodes these data using XML tags that are effectively a standard in life sciences literature. Allowing authors to mark-up their own work will help increase the amount and quality of machine-readable literature metadata.

As children build a script for each emotion, in what order do they add each subevent? Preschoolers (N = 108, three to five years), were asked to name the protagonist's emotion in…

  11. Tiotropium in the add-on treatment of asthma in adults: clinical trial evidence and experience.

    2016-12-01

    Asthma is a chronic inflammatory airway disease, and its treatment is frequently challenging despite detailed national and international guidelines. While basic anti-inflammatory therapy usually consists of inhaled corticosteroids in doses adapted to the asthma severity, add-on treatment with bronchodilators is essential in more severe asthma. Only recently, the long-acting anticholinergic tiotropium was introduced into the GINA guidelines. This review reports on the studies that have been performed with tiotropium in adult asthmatic patients. Following early proof-of-concept studies, several studies with tiotropium as an add-on therapy to inhaled corticosteroids (ICS), with or without a long-acting beta agonist (LABA), demonstrated convincing clinical benefit for patients. Important lung function parameters and quality of life scores significantly improved shortly after onset of the add-on therapy with tiotropium, and some studies even demonstrated non-inferiority against salmeterol. All studies reported an excellent safety profile of tiotropium. The still growing body of tiotropium studies, both in adults and children, will help to identify the position of tiotropium in future asthma guidelines and might also indicate which patients benefit most from an add-on therapy with tiotropium. © The Author(s), 2016.

  18. Neural biomarkers for dyslexia, ADHD and ADD in the auditory cortex of children

    2016-07-01

    Full Text Available Dyslexia, attention deficit hyperactivity disorder (ADHD, and attention deficit disorder (ADD show distinct clinical profiles that may include auditory and language-related impairments. Currently, an objective brain-based diagnosis of these developmental disorders is still unavailable. We investigated the neuro-auditory systems of dyslexic, ADHD, ADD, and age-matched control children (N=147 using neuroimaging, magnet-encephalography and psychoacoustics. All disorder subgroups exhibited an oversized left planum temporale and an abnormal interhemispheric asynchrony (10-40 ms of the primary auditory evoked P1-response. Considering right auditory cortex morphology, bilateral P1 source waveform shapes, and auditory performance, the three disorder subgroups could be reliably differentiated with outstanding accuracies of 89-98%. We therefore for the first time provide differential biomarkers for a brain-based diagnosis of dyslexia, ADHD, and ADD. The method allowed not only a clear discrimination between two subtypes of attentional disorders (ADHD and ADD, a topic controversially discussed for decades in the scientific community, but also revealed the potential for objectively identifying comorbid cases. Noteworthy, in children playing a musical instrument, after three and a half years of training the observed interhemispheric asynchronies were reduced by about 2/3, thus suggesting a strong beneficial influence of music experience on brain development. These findings might have far-reaching implications for both research and practice and enable a profound understanding of the brain-related etiology, diagnosis, and musically based therapy of common auditory-related developmental disorders and learning disabilities.

  19. ATRX ADD Domain Links an Atypical Histone Methylation Recognition Mechanism to Human Mental-Retardation Syndrome

    ATR-X (alpha-thalassemia/mental retardation, X-linked) syndrome is a human congenital disorder that causes severe intellectual disabilities. Mutations in the ATRX gene, which encodes an ATP-dependent chromatin-remodeler, are responsible for the syndrome. Approximately 50% of the missense mutations in affected persons are clustered in a cysteine-rich domain termed ADD (ATRX-DNMT3-DNMT3L, ADD{sub ATRX}), whose function has remained elusive. Here we identify ADD{sub ATRX} as a previously unknown histone H3-binding module, whose binding is promoted by lysine 9 trimethylation (H3K9me3) but inhibited by lysine 4 trimethylation (H3K4me3). The cocrystal structure of ADD{sub ATRX} bound to H3{sub 1-15}K9me3 peptide reveals an atypical composite H3K9me3-binding pocket, which is distinct from the conventional trimethyllysine-binding aromatic cage. Notably, H3K9me3-pocket mutants and ATR-X syndrome mutants are defective in both H3K9me3 binding and localization at pericentromeric heterochromatin; thus, we have discovered a unique histone-recognition mechanism underlying the ATR-X etiology.

    2017-06-01

    Perforating keratoplasty shows good morphological results with a clear cornea; however, a limiting factor is often the resulting astigmatism, which cannot be corrected with either glasses or contact lenses (CL) in up to 20% of the patients. We retrospectively investigated 15 patients after pseudophakic perforating keratoplasty, who received implantation of toric add-on intraocular lenses (IOL) to correct astigmatism. The mean preoperative astigmatism of 6.5 diopter (dpt) could be reduced to a mean postoperative value of 1.0 dpt. The mean visual acuity could be improved from a preoperative value of sc one case of a lens extension tear. Based on our good experiences we now provide toric add-on IOL to all patients with pseudophakic perforating keratoplasty when this cannot be corrected or only insufficiently corrected by conservative methods.

    2017-12-15

    We have proposed and studied a novel channel add-drop filter (ADF) based on a single Fabry-Perot resonator. The resonator consists of two mode-conversion Bragg grating reflectors separated by a wide waveguide that laterally coupled to two narrow waveguides. It behaves like a traveling-wave resonator where fields are coupled to the buses in one direction. Compact and narrowband ADFs are achieved with dropping efficiencies higher than 95%, as shown by the three-dimensional finite-difference time-domain simulations. In addition, the proposed device is applied to realize an eight-channel add-drop multiplexer in the C-band by cascading the ADFs with adjusted channel wavelengths.

  15. ADD students with and without dyslexia differ in sensitivity to rhyme and alliteration.

    Ackerman, P T; Dykman, R A; Gardner, M Y

    1990-05-01

    Children with attention deficit disorder (ADD) and dyslexia (n = 82) made significantly more errors than normally reading children with ADD (n = 83) on a simple auditory test of phonological sensitivity to rhyme and alliteration (Bradley, 1984). A subgroup of children with dyslexia who were sensitive to rhyme and alliteration had higher scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) Spatial factor than a dyslexic subgroup who were phonologically insensitive. In multiple regression analyses, age-corrected phonological sensitivity scores contributed significantly to the prediction of both reading and spelling Wide Range Achievement Test (WRAT) scores, this beyond the contribution of WISC-R variables. Of interest for dyslexia subtyping theories, Spatial factor scores had a subtractive effect in these regression analyses.

    Olson, Craig L.

    2001-01-01

    Heavy ion beam transport through the containment chamber plays a crucial role in all heavy ion fusion (HIF) scenarios. Here, several parameters are used to characterize the operating space for HIF beams; transport modes are assessed in relation to evolving target/accelerator requirements; results of recent relevant experiments and simulations of HIF transport are summarized; and relevant instabilities are reviewed. All transport options still exist, including (1) vacuum ballistic transport, (2) neutralized ballistic transport, and (3) channel-like transport. Presently, the European HIF program favors vacuum ballistic transport, while the US HIF program favors neutralized ballistic transport with channel-like transport as an alternate approach. Further transport research is needed to clearly guide selection of the most attractive, integrated HIF system

    Full Text Available This paper invested a bilateral waveform similarity overlap-and-add algorithm for voice packet lost. Since Packet lost will cause the semantic misunderstanding, it has become one of the most essential problems in speech communication. This investment is based on waveform similarity measure using overlap-and-Add algorithm and provides the bilateral information to enhance the speech signal reconstruction. Traditionally, it has been improved that waveform similarity overlap-and-add (WSOLA technique is an effective algorithm to deal with packet loss concealment (PLC for real-time time communication. WSOLA algorithm is widely applied to deal with the length adaptation and packet loss concealment of speech signal. Time scale modification of audio signal is one of the most essential research topics in data communication, especially in voice of IP (VoIP. Herein, the proposed the bilateral WSOLA (BWSOLA that is derived from WSOLA. Instead of only exploitation one direction speech data, the proposed method will reconstruct the lost voice data according to the preceding and cascading data. The related algorithms have been developed to achieve the optimal reconstructing estimation. The experimental results show that the quality of the reconstructed speech signal of the bilateral WSOLA is much better compared to the standard WSOLA and GWSOLA on different packet loss rate and length using the metrics PESQ and MOS. The significant improvement is obtained by bilateral information and proposed method. The proposed bilateral waveform similarity overlap-and-add (BWSOLA outperforms the traditional approaches especially in the long duration data loss.

    When fit with monovision, most early presbyopes (aged 40 to 50 years) accommodated to near objects by focusing the distance corrected eye, leaving the near corrected eye myopically defocused with reduced image quality. A few were able to switch focus to the near corrected eye retaining a consistently focused image in one eye over a wider range of distances. The aim of this study was to examine accommodation behavior, pupil responses, and resultant image quality of early presbyopes fit with either bilateral or unilateral (monovision) near adds. Accommodative response and pupil size of 19 subjects (27 to 60 years), including 13 early presbyopes (40 to 50 years), were measured using an aberrometer as a binocularly viewed 20/40 letter E was moved from 2 m to 20 cm. Each subject was fit with different refractive strategies: bilateral distance correction, bilateral +2 diopters (D) near add, and unilateral +2 D near add placed over the measured right eye or unmeasured left eye. Monochromatic image quality was quantified using the Visual Strehl ratio metric. With bilateral +2 D near add, all early presbyopes mostly refrained from accommodating (gain = 0.22 D/D) until the target approached closer than the 50-cm far point, and they then accommodated accurately until their maximum accommodative amplitude was reached. With monovision, most (10 of 13 early presbyopes) accommodated to focus the distance corrected eye, leaving the near corrected eye myopically defocused with reduced image quality. As stimulus distance became closer than their distance corrected eye's near point, they continued to exert maximum accommodation. Only two early presbyopes relaxed their accommodation to "switch" focus to the near corrected eye as target distance was reduced, and these two did not experience bilateral drop in image quality as stimulus distance became closer than the near point of the distance corrected eye. Our data suggest that many early presbyopes will not initially adopt an

    Full Text Available Karoline von Websky, Christoph Reichetzeder, Berthold Hocher Institute of Nutritional Science, University of Potsdam, Potsdam-Rehbrücke, Germany Abstract: Type 2 diabetes mellitus (T2DM is a highly prevalent, progressive disease that often is poorly controlled. The combination of an incretin-based therapy and insulin is a promising approach to optimize the management of glycemic control without hypoglycemia and weight gain. Linagliptin, a recently approved oral dipeptidyl peptidase-4 inhibitor, has a unique pharmacological profile. The convenient, once-daily dosing does not need adjustment in patients with hepatic and/or renal impairment. In clinical studies linagliptin shows an important reduction of blood glucose with an overall safety profile similar to that of placebo. So far, the combination of linagliptin and insulin has been tested in three major clinical studies in different populations. It has been shown that linagliptin is an effective and safe add-on therapy to insulin in patients with T2DM. The efficacy and safety of this combination was also shown in vulnerable, elderly T2DM patients and in patients with T2DM and renal impairment. Favorable effects regarding the counteraction of hypoglycemia make linagliptin especially interesting as an add-on therapy to insulin. This review aims to present the existing clinical studies on the efficacy and safety of linagliptin as add-on therapy to insulin in patients with T2DM in the context of current literature. Additionally, the possible advantages of linagliptin as an add-on therapy to insulin in relation to cardiovascular safety, patient-centered therapy and the prevention of hypoglycemia, are discussed.

    2017-03-01

    Scanning confocal microscopy is a standard choice for many fluorescence imaging applications in basic biomedical research. It is able to produce optically sectioned images and provide acquisition versatility to address many samples and application demands. However, scanning a focused point across the specimen limits the speed of image acquisition. As a result, scanning confocal microscope only works well with stationary samples. Researchers have performed parallel confocal scanning using digital-micromirror-device (DMD), which was used to project a scanning multi-point pattern across the sample. The DMD based parallel confocal systems increase the imaging speed while maintaining the optical sectioning ability. In this paper, we report the development of an add-on kit for high-speed and low-cost confocal microscopy. By adapting this add-on kit to an existing regular microscope, one can convert it into a confocal microscope without significant hardware modifications. Compared with current DMD-based implementations, the reported approach is able to recover multiple layers along the z axis simultaneously. It may find applications in wafer inspection and 3D metrology of semiconductor circuit. The dissemination of the proposed add-on kit under $1000 budget could also lead to new types of experimental designs for biological research labs, e.g., cytology analysis in cell culture experiments, genetic studies on multicellular organisms, pharmaceutical drug profiling, RNA interference studies, investigation of microbial communities in environmental systems, and etc.

  3. The Dnmt3L ADD Domain Controls Cytosine Methylation Establishment during Spermatogenesis

    Full Text Available A critical aspect of mammalian gametogenesis is the reprogramming of genomic DNA methylation. The catalytically inactive adaptor Dnmt3L is essential to ensuring this occurs correctly, but the mechanism by which it functions is unclear. Using gene targeting to engineer a single-amino-acid mutation, we show that the Dnmt3L histone H3 binding domain (ADD is necessary for spermatogenesis. Genome-wide single-base-resolution DNA methylome analysis of mutant germ cells revealed overall reductions in CG methylation at repetitive sequences and non-promoter CpG islands. Strikingly, we also observe an even more severe loss of non-CG methylation, suggesting an unexpected role for the ADD in this process. These epigenetic deficiencies were coupled with defects in spermatogonia, with mutant cells displaying marked changes in gene expression and reactivation of retrotransposons. Our results demonstrate that the Dnmt3L ADD is necessary for Dnmt3L function and full reproductive fitness.

  10. Which thiazide to choose as add-on therapy for hypertension?

    Full Text Available Vivencio Barrios,1 Carlos Escobar2 1Department of Cardiology, Hospital Ramon y Cajal, 2Department of Cardiology, Hospital La Paz, Madrid, Spain Abstract: Combined therapy is required in the majority of patients with hypertension to achieve blood pressure (BP targets. Although different antihypertensive drugs can be combined, not all combinations are equally effective and safe. In this context, the combination of a renin angiotensin system inhibitor with a diuretic, usually a thiazide, particularly hydrochlorothiazide (HCTZ or thiazide-like diuretics, such as chlorthalidone or indapamide, is recommended. However, not all diuretics are equal. Although HCTZ, chlorthalidone, and indapamide as add-on therapy effectively reduce BP levels, the majority of studies have obtained greater BP reductions with chlorthalidone or indapamide than with HCTZ. Moreover, there are data showing benefits with chlorthalidone or indapamide beyond BP. Thus, chlorthalidone seems to have pleiotropic effects beyond BP reduction. Moreover, compared with placebo, chlorthalidone has small effects on fasting glucose and total cholesterol, and compared with HCTZ, chlorthalidone achieves significantly lower total cholesterol and low-density lipoprotein cholesterol levels. Similarly, indapamide has demonstrated no negative impact on glucose or lipid metabolism. More importantly, although head-to-head clinical trials comparing the effects of indapamide or chlorthalidone with HCTZ are not available, indirect comparisons and post hoc analyses suggest that the use of chlorthalidone or indapamide is associated with a reduction in cardiovascular events. Despite this, the most frequent diuretic used in clinical practice as add-on therapy for hypertension is HCTZ. The purpose of this review is to update the published data on the efficacy and safety of HCTZ, chlorthalidone, and indapamide as add-on therapy in patients with hypertension.

    2013-06-10

    The validity of the method in which total body score (TBS) and accumulated degree-days (ADD) are used to estimate the postmortem interval (PMI) is examined. TBS and ADD were recorded for 232 days in northern South Africa, which has temperatures between 17 and 28 °C in summer and 6 and 20 °C in winter. Winter temperatures rarely go below 0°C. Thirty pig carcasses, which weighed between 38 and 91 kg, were used. TBS was scored using the modified method of Megyesi et al. [1]. Temperature was acquired from an on site data logger and the weather station bureau; differences between these two sources were not statistically significant. Using loglinear random-effects maximum likelihood regression, an r(2) value for ADD (0.6227) was produced and linear regression formulae to estimate PMI from ADD with a 95% prediction interval were developed. The data of 16 additional pigs that were placed a year later were then used to validate the accuracy of this method. The actual PMI and ADD were compared to the estimated PMI and ADD produced by the developed formulae as well as the estimated PMIs within the 95% prediction interval. A validation of the study produced poor results as only one pig of 16 fell within the 95% interval when using the formulae, showing that ADD has limited use in the prediction of PMI in a South African setting.

    The objective of this study was to examine the prevalence and correlates of self-reported attention deficit disorder (ADD)/ADHD in Canadian adults. Prevalence of self-reported ADD/ADHD was examined in a large national sample of Canadians ( n = 16,957). Demographic variables, lifetime, and current psychiatric comorbidities were then compared in a group of adults with self-reported ADD/ADHD ( n = 488) and an age- and gender-matched control group ( n = 488). The prevalence of self-reported ADD/ADHD was 2.9%. Significantly higher lifetime and current prevalence rates of major depressive disorder, bipolar I and II disorders, generalized anxiety disorder, and substance use disorders were observed in the ADD/ADHD group compared with the control group. Within the ADD/ADHD group, lifetime and 12-month prevalence rates of major depressive disorder and generalized anxiety disorder were significantly higher in women, whereas lifetime and current rates of some substance use disorders were significantly higher in men. In a national sample of Canadian adults, self-reported ADD/ADHD was associated with significant psychiatric comorbidity. Gender differences were also noted.

    Greater reductions in glycated haemoglobin (HbA1c) with saxagliptin, a dipeptidyl peptidase-4 inhibitor, versus placebo add-on in patients with type 2 diabetes who had inadequate glycaemic control with dapagliflozin 10 mg/d plus metformin were demonstrated after 24 weeks of treatment. Results over 52 weeks of treatment were assessed in this analysis. Patients (mean baseline HbA1c 7.9%) receiving open-label dapagliflozin 10 mg/d plus metformin were randomized to double-blind saxagliptin 5 mg/d or placebo add-on. The adjusted mean change from baseline to week 52 in HbA1c was greater with saxagliptin than with placebo add-on -0.38% vs 0.05%; difference -0.42% (95% confidence interval -0.64, -0.20)]. More patients achieved the HbA1c target of add-on (29% vs 13%), and fewer patients were rescued or discontinued the study for lack of glycaemic control with saxagliptin than with placebo add-on (19% vs 28%). Reductions from baseline in body weight (≤1.5 kg) occurred in both groups. Similar proportions of patients reported ≥1 adverse event with saxagliptin (58.2%) and placebo add-on (58.0%); no new safety signals were detected. Hypoglycaemia was infrequent in both treatment groups (≤2.5%), with no major episodes. The rate of urinary tract infections was similar in the saxagliptin and placebo add-on groups (7.8% vs 7.4%). The incidence of genital infections was 3.3% with saxagliptin versus 6.2% with placebo add-on. Triple therapy with saxagliptin add-on to dapagliflozin plus metformin for 52 weeks resulted in sustained improvements in glycaemic control without an increase in body weight or increased risk of hypoglycaemia. © 2016 John Wiley & Sons Ltd.

    Avoidant personality disorder (AvPD) has a high level of symptom overlap and comorbidity with generalized social anxiety disorder (GSAD). We examined whether the presence of comorbid AvPD adds significant clinically relevant information for individuals seeking treatment for GSAD. Results suggested that AvPD was significantly associated with poorer quality of life and greater disability in univariate, but not multivariate analyses. Endorsement of more AvPD symptoms was associated with increased disability, increased risk of intimacy, and lower social support, even after covariate adjustment. Specifically, AvPD item 3, hard to be "open" even with people you are close to, was most strongly correlated with quality of life and disability. A binary diagnosis of AvPD alone adds little beyond a marker of greater GSAD severity and depression among patients with GSAD, while a specific feature of AvPD not captured by the GSAD diagnosis, namely emotional guardedness, may be associated with greater impairment.

    Colonoscopy is the gold standard for colorectal cancer prevention; however, it is still an imperfect modality. Precancerous lesions can be lost during screening examinations, thus increasing the risk of interval cancer. A variety of factors either patient-, or endoscopist dependent or even the procedure itself may contribute to loss of lesions. Sophisticated modalities including advanced technology endoscopes and add-on devices have been developed in an effort to eliminate colonoscopy's drawbacks and maximize its ability to detect potentially culprit polyps. Novel colonoscopes aim to widen the field of view. They incorporate more than one cameras enabling simultaneous image transmission. In that way the field of view can expand up to 330°. On the other hand a plethora of add-on devices attachable on the standard colonoscope promise to detect lesions in the proximal aspect of colonic folds either by offering a retrograde view of the lumen or by straightening the haustral folds during withdrawal. In this minireview we discuss how these recent advances affect colonoscopy performance by improving its quality indicators (cecal intubation rate, adenoma detection rate) and other metrics (polyp detection rate, adenomas per colonoscopy, polyp/adenoma miss rate) associated with examination's outcomes.

  2. A low-complexity add-on score for protein remote homology search with COMER.

    Protein sequence alignment forms the basis for comparative modeling, the most reliable approach to protein structure prediction, among many other applications. Alignment between sequence families, or profile-profile alignment, represents one of the most, if not the most, sensitive means for homology detection but still necessitates improvement. We aim at improving the quality of profile-profile alignments and the sensitivity induced by them by refining profile-profile substitution scores. We have developed a new score that represents an additional component of profile-profile substitution scores. A comprehensive evaluation shows that the new add-on score statistically significantly improves both the sensitivity and the alignment quality of the COMER method. We discuss why the score leads to the improvement and its almost optimal computational complexity that makes it easily implementable in any profile-profile alignment method. An implementation of the add-on score in the open-source COMER software and data are available at https://sourceforge.net/projects/comer. The COMER software is also available on Github at https://github.com/minmarg/comer and as a Docker image (minmar/comer). mindaugas.margelevicius@bti.vu.lt.

    Evaluation of efficacy and tolerability of zonisamide (ZNS) used as an add-on treatment in patients with chronic focal epilepsies. Retrospective data analysis in 74 patients (38 men, 36 women), age 17-61 years (mean 35 years). Duration of epilepsy was 2-50 years (mean 23.3 years). Additional antiepileptic drugs 2-5 (mean 2.7). The ZNS daily dosage varied between 100 mg and 500 mg (mean 368 mg). Seizure frequency could be estimated in 50 patients; it decreased by at least 50% in 11 patients (22%), remained unchanged in 28 patients (56%), and increased by at least 50% in 11 patients (22%). None of the patients achieved complete seizure control. Side effects were seen in 45/74 patients (60.8%). Adverse events resulting in discontinuation of treatment with ZNS were documented in 24 patients (32.4%). Out of 70 patients, 34 (48.5%) remained on ZNS 12 months after the onset of therapy. In this study, ZNS proved to be an antiepileptic drug with a comparatively low anticonvulsant efficacy as an add-on treatment in patients with chronic focal epilepsies.

    A high-dose administration of inhaled corticosteroid is effective in the majority of patients with bronchial asthma, but is often difficult to attain sufficient control in certain subsets of patients. Omalizumab has recently emerged as a promising drug for bronchial asthma. To assess its add-on effect we administered omalizumab to patients with uncontrolled atopic asthma for more than 16 weeks and gave them questionnaires. The study population comprised 9 patients with frequent asthmatic symptoms despite the administration of high-dose inhaled corticosteroid and other disease controllers. We scored disease control using the Asthma Health Questionnaire-33-Japan and the Asthma Control Test, and evaluated the frequencies of short-acting beta2-agonist use for rescue and drip infusion of theophyllines and/or systemic steroids in a retrospective fashion. Asthmatic scores were significantly improved after 16 weeks of omalizumab therapy. The frequencies of reliever use and drip infusion were also decreased. These trends were present even in patients in whom no aeroallergen-specific IgE antibodies were detected. No statistically significant side effects were observed. Our study confirmed the add-on effect of omalizumab based on evaluation by simple questionnaires. Further studies are needed to clarify whether omalizumab therapy is suitable for patients without specific IgE antibodies.

    Silver nanoparticles (AgNPs) are of interest due to their antimicrobial attributes, which are derived from their inherent redox instability and subsequent release of silver ions. At the same time, this instability is a substantial challenge for achieving stable long-term storage for on-demand use of AgNPs. In this study, we describe and validate a "just add water" approach for achieving suspensions of principally singly dispersed AgNPs. By lyophilizing (freeze drying) the formulated AgNPs into a solid powder, or cake, water is removed thereby eliminating solution-based chemical changes. Storing under inert gas further reduces surface reactions such as oxidation. An example of how to optimize a lyophilization formulation is presented, as well as example formulations for three AgNP core sizes. This "just add water" approach enables ease of use for the researcher desiring on-demand singly dispersed AgNP suspensions from a single master batch. Implementation of this methodology will enable studies to be performed over long periods of time and across different laboratories using particles that are identical chemically and physically and available on-demand. In addition, the approach of freeze drying and on-demand reconstitution by adding water has enabled the development of AgNP reference materials with the required shelf-life stability, one of the principal objectives of this research.

    To investigate whether sodium tanshinone IIA silate (STS) as an add-on therapy to conventional treatment may provide additional benefits for patients with unstable angina pectoris (UAP) and is associated with changes in profiles of serum inflammatory factors. Eighty patients diagnosed with UAP were randomly divided into two groups for the 2-week treatment. The control group received conventional therapy, while the treatment group was given intravenous STS (0.06 mg in 250 mL, once daily) as an add-on therapy to the conventional medications. The therapeutic efficacy and changes in serum levels of several inflammatory cytokines, including monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor alpha (TNF-α), peroxisome proliferator-activated receptor (PPAR-γ), and high-sensitivity C-reactive protein (hs-CRP) from baseline were determined and compared between the two group. The clinical symptoms of all patients in both groups were improved after treatment. The overall rate of effectiveness was 97.5% in the treatment group vs. 80.0% in the control group. Serum levels of MCP-1, TNF-α, and hs-CRP levels were significantly reduced in both groups (P<0.01), whereas the reduction was greater in patients receiving additional STS (P<0.05). PPAR-γ was significantly elevated in both groups (P<0.01). STS in combination with conventional treatment may be associated with better outcomes in patients with UAP.

    Full Text Available Jonathan D Litten1, JungHun Choi2, David Drozek31Department of Mechanical Engineering; 2Department of Mechanical Engineering and Biomedical Engineering Program; 3College of Osteopathic Medicine, Department of Specialty Medicine, Ohio University, Athens, OH, USAAbstract: A colonoscopy add-on device has been developed to reduce intubation time without modification of the current colonoscope and peripheral devices. One of the main purposes of the system is to minimize trauma caused by the distal tip of the colonoscope. The detachable sensory fixture at the end of the distal tip measures the distance between the distal tip and the colon wall in three directions, and the actuation system attached at the base of the colonoscope controls the distal tip by rotating two dial knobs. The device controls the distal tip to minimize contact between the distal tip and the colon wall, and the distal tip ideally points out the next possible lumen. A compatibility test of the infrared sensory system was carried out, and the design of the actuation system was accomplished. The system is integrated and controlled by a microprocessor. The device was tested in a silicon colon and porcine intestine. The results showed that a colonoscopist successfully reached the cecum with the aid of the colonoscopy add-on device without significant contact between the colon wall and the distal tip. The colonoscopy aid device was very helpful for the novice colonoscopist.Keywords: colonoscope, infrared sensors, intubation, trauma, colonoscopy training model

  8. The Politics, Development and Problems of Small Irrigation Dams in Malawi: Experiences from Mzuzu ADD

    Directory of Open Access Journals (Sweden)

    Bryson Gwiyani Nkhoma

    2011-10-01

    Full Text Available The paper examines the progress made regarding the development of small irrigation dams in Malawi with the view of establishing their significance in improving rural livelihoods in the country. The paper adopts a political economy theory and a qualitative research approach. Evidence from Mzuzu Agricultural Development Division (ADD, where small reservoirs acquire specific relevance, shows that despite the efforts made, the development of small dams is making little progress. The paper highlights that problems of top-down planning, high investment costs, negligence of national and local interests, over-dependency on donors, and conflicts over the use of dams – which made large-scale dams unpopular in the 1990s – continue to affect the development of small irrigation dams in Malawi. The paper argues that small irrigation dams should not be simplistically seen as a panacea to the problems of large-scale irrigation dams. Like any other projects, small dams are historically and socially constructed through interests of different actors in the local settings, and can only succeed if actors, especially those from formal institutions, develop adaptive learning towards apparent conflicting relations that develop among them in the process of implementation. In the case of Mzuzu ADD, it was the failure of the government to develop this adaptive learning to the contestations and conflicts among these actors that undermined successful implementation of small irrigation dams. The paper recommends the need to consider local circumstances, politics, interests, rights and institutions when investing in small irrigation dams.

    This review is an update of a previously published review in the Cochrane Database of Systematic Reviews (Issue 7, 2014) on 'Felbamate as an add-on therapy for refractory epilepsy'. Epilepsy is a chronic and disabling neurologic disorder, affecting approximately 1% of the population. Up to 30% of people with epilepsy have seizures that are resistant to currently available drugs. Felbamate is one of the second-generation antiepileptic drugs and we have assessed its effects as an add-on therapy to standard drugs in this review. To evaluate the efficacy and tolerability of felbamate versus placebo when used as an add-on treatment for people with refractory partial-onset epilepsy. For the latest update we searched the Cochrane Epilepsy Specialized Register, CENTRAL, MEDLINE, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform, up to 20 October 2016. There were no language and time restrictions. We reviewed the reference lists of retrieved studies to search for additional reports of relevant studies. We also contacted the manufacturers of felbamate and experts in the field for information about any unpublished or ongoing studies. Randomised placebo-controlled add-on studies of people of any age with refractory partial-onset seizures. The studies could be double-blind, single-blind or unblinded and could be of parallel or cross-over design. Two review authors independently selected studies for inclusion and extracted information. We resolved disagreements by discussion. If disagreements persisted, the third review author arbitrated. We assessed the following outcomes: 50% or greater reduction in seizure frequency; absolute or percentage reduction in seizure frequency; treatment withdrawal; adverse effects; quality of life. We included four randomised controlled trials with a total of 236 participants. Two trials were parallel design, the third had a two-period cross-over design, and the fourth had a three-period cross-over design. Two studies

    To explore the potential occurrence of long-term side effects and tolerability of gonadotropin-releasing hormone agonist (GnRHa) plus 2 different add-back regimens in adolescent patients with endometriosis DESIGN: Follow-up questionnaire sent in 2016 to patients who participated in a drug trial between 2008-2012 SETTING: Tertiary care center in Boston, MA. Females with surgically confirmed endometriosis (n=51) who enrolled in a GnRHa plus add-back trial as adolescents INTERVENTIONS: Leuprolide depot 11.25 mg intramuscular injection every 3 month, plus oral norethindrone acetate 5 mg daily or oral norethindrone acetate 5 mg daily plus oral conjugated equine estrogens 0.625 mg daily. Side effects during and after treatment, irreversible side effects, changes in pain, overall satisfaction RESULTS: The response rate was 61%. Almost all (96%) reported side effects during treatment; 80% reported side effects lasting > 6 months after stopping treatment. Almost half (45%) reported side effects they considered irreversible, including memory loss, insomnia, and hot flashes. Despite side effects, subjects rated GnRHa plus add-back as the most effective hormonal medication for treating endometriosis pain; two thirds (16/25) would recommend it to others. More subjects who received a modified two drug add-back regimen versus standard one drug add-back would recommend GnRHa and felt it was the most effective hormonal medication. Subjects felt GnRHa plus add-back was effective and would recommend it to others, despite significant side effects. Those who received two drug add-back reported more success than those who received standard add-back. A subset of patients reported irreversible side effects. Copyright © 2018.

    The Psychiatric Assessment Schedule for Adult with Developmental Disability (PAS-ADD) is an international reference tool for the diagnosis and assessment of mental health problems and behavioural disorders among people with intellectual disabilities. Although the original PAS-ADD instrument has been validated in the Spanish language, the shorter PAS-ADD Checklist has yet not been validated. The aim of this study is to validate the PAS-ADD Checklist for the Spanish population. The PAS-ADD Checklist Questionnaire was administered to 208 adults with intellectual disabilities at a vocational centre in Madrid, Spain. The psychometric analyses included internal consistency, inter-rater and test-retest reliability, Varimax rotation factor analysis for construct validity, criterion validity and feasibility. The Cronbach's alpha was 0.80 for the overall questionnaire and between 0.40 and 0.79 for the subscales. The Kappa coefficients for test-retest and inter-rater reliability were between 0.66 and 0.80. Varimax rotation factor analysis showed five well-defined factors. The Kappa coefficients for criterion validity were between 0.30 and 0.70. Feasibility was also good. The PAS-ADD Checklist is a feasible and reliable instrument for carrying out initial assessment of the mental health status of adults with intellectual disabilities, referring cases to more specialised diagnosis and treatment. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

  20. Experimental re-evaluation of flunarizine as add-on antiepileptic therapy

    Full Text Available Background: Experimental studies have found several calcium channel blockers with anticonvulsant property. Flunarizine is one of the most potent calcium channel blockers, which has shown anticonvulsant effect against pentylenetetrazole (PTZ and maximal electroshock (MES-induced seizures. However, further experimental and clinical trials have shown varied results. We conducted a PTZ model experimental study to re-evaluate the potential of flunarizine for add-on therapy in the management of refractory epilepsy. Materials and Methods: Experiments were conducted in PTZ model involving Swiss strain mice. Doses producing seizures in 50% and 99% mice, i.e. CD 50 and CD 99 values of PTZ were obtained from the dose-response study. Animals received graded, single dose of sodium valproate (100-300 mg/kg, lamotrigine (3-12 mg/kg and flunarizine (5-20 mg/kg, and then each group of mice was injected with CD 99 dose of PTZ (65mg/kg i.p.. Another group of mice received single ED 50 dose (dose producing seizure protection in 50% mice of sodium valproate and flunarizine separately in left and right side of abdomen. Results were analysed by Kruskal-Wallis ANOVA on Ranks test. Results: As compared to control, sodium valproate at 250 mg/kg and 300 mg/kg produced statistical significant seizure protection. At none of the pre-treatment dose levels of lamotrigine, the seizure score with PTZ differed significantly from that observed in the vehicle-treated group. Pre-treatment with flunarizine demonstrated dose-dependent decrease in the seizure score to PTZ administration. As compared to control group, flunarizine at 20 mg/kg produced statistical significant seizure protection. Conclusion: As combined use of sodium valproate and flunarizine has shown significant seizure protection in PTZ model, flunarizine has a potential for add-on therapy in refractory cases of partial seizures. It is therefore, we conclude that further experimental studies and multicenter clinical

  2. Interaction and dynamics of add-atoms with 2-dimensional structures

    CERN Multimedia

    The interaction and dynamics of add-atoms with graphene, graphene-derivate structures and, later, MoSi$_2$, two-dimensional – single and few – atomic layers will be studied with the Perturbed Angular Correlation – PAC – technique. Graphene is also envisaged as new platform for growing semiconductor nanostructure devices, such as quantum dots and as a particularly powerful catalyst. Understanding nucleation of nanostructures and clusters on graphene and related phases in wet conditions as they are used in chemical methods in research and industry require complementary studies. These systems will therefore be studied systematically using radioactive probe atoms attaching via a transfer media (e.g., water in catalysis process) or being deposited with soft-landing techniques under vacuum and UHV conditions, as put in place at the ASPIC setup at ISOLDE. The hyperfine fields obtained under different environments are expected to reveal basic information on the rich atomic and physical mechanisms associated w...

    With the development of optical fiber communication, dense wavelength division multiplexing (DWDM) system is important for the rapid management of multi-wavelength in the core node of the optical transmission network. In this paper, a reconfigurable optical add-drop multiplexer (ROADM) based on the tunable Fabry-Perot (F-P) array is proposed. An optical switch with high isolation and low crosstalk is designed by using the characteristics of filtering and tuning for the F-P array. The principle, structure, and function of the tunable F-P array are introduced. The characteristics of filtering and tuning for the F-P filter are also calculated, and the factor for the isolation, crosstalk, response time and insertion loss are analyzed. A single physical channel ROADM with 16 signal channels, which operates in C-band, is designed and optimized by simulation.

  5. Addiction surplus: the add-on margin that makes addictive consumptions difficult to contain.

    Adams, Peter J; Livingstone, Charles

    2015-01-01

    Addictive consumptions generate financial surpluses over-and-above non-addictive consumptions because of the excessive consumption of addicted consumers. This add-on margin or 'addiction surplus' provides a powerful incentive for beneficiaries to protect their income by ensuring addicted consumers keep consuming. Not only that, addiction surplus provides the financial base that enables producers to sponsor activities which aim to prevent public health initiatives from reducing consumption. This paper examines the potency of addiction surplus to engage industry, governments and communities in an on-going reliance on addiction surplus. It then explores how neo-liberal constructions of a rational consumer disguise the ethical and exploitative dynamics of addiction surplus by examining ways in which addictive consumptions fail to conform to notions of autonomy and rationality. Four measures are identified to contain the distorting effects of addiction surplus. Copyright © 2014 Elsevier B.V. All rights reserved.

    Survival curves are frequently used for reporting survival or mortality outcomes of experimental pharmacological/toxicological studies and of clinical trials. Microsoft Excel is a simple and widely used tool for creation of numerous types of graphic presentations however it is difficult to create step-wise survival curves in Excel. Considering the familiarity of clinicians and biomedical scientists with Excel, an algorithm survival curves in Excel worksheet (SCEW) has been developed for easy creation of survival curves directly in Excel worksheets. The algorithm has been integrated in the form of Excel add-in for easy installation and usage. The program is based on modification of frequency data for binary break-up using the spreadsheet formula functions whereas a macro subroutine automates the creation of survival curves. The advantages of this program are simple data input, minimal procedural steps and the creation of survival curves in the familiar confines of Excel.

    This is an updated version of the Cochrane Review published in the Cochrane Library 2011, Issue 12.The majority of people with epilepsy have a good prognosis, but up to 30% of people continue to have seizures despite several regimens of antiepileptic drugs. In this review, we summarized the current evidence regarding eslicarbazepine acetate (ESL) when used as an add-on treatment for drug-resistant partial epilepsy. To evaluate the efficacy and tolerability of ESL when used as an add-on treatment for people with drug-resistant partial epilepsy. The searches for the original review were run in November 2011. Subsequently, we searched the Cochrane Epilepsy Group Specialized Register (6 December 2016), the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 11) and MEDLINE (1946 to 6 December 2016). There were no language restrictions. We reviewed the reference lists of retrieved studies to search for additional reports of relevant studies. We also contacted the manufacturers of ESL and experts in the field for information about any unpublished or ongoing studies. Randomized placebo controlled double-blind add-on trials of ESL in people with drug-resistant partial epilepsy. Two review authors independently selected trials for inclusion and extracted data. Outcomes investigated included 50% or greater reduction in seizure frequency, seizure freedom, treatment withdrawal, adverse effects, and drug interactions. Primary analyses were by intention to treat (ITT). The dose-response relationship was evaluated in regression models. We included five trials (1799 participants) rated at low risk of bias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% confidence interval (CI) for 50% or greater reduction in seizure frequency was 1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL reduced seizure frequency with an increase in efficacy with increasing doses of ESL. ESL was significantly associated with seizure freedom

    This study investigated the long-term efficacy and safety of empagliflozin as add-on to metformin plus sulphonylurea in patients with type 2 diabetes mellitus (T2DM). Of 666 patients treated with empagliflozin 10 mg, empagliflozin 25 mg or placebo once daily for 24 weeks, 472 patients (70.9%) were treated in a double-blind extension trial for ≥52 weeks. Pre-specified exploratory endpoints included changes from baseline in HbA(1c), weight and blood pressure at week 76. At week 76, adjusted mean differences versus placebo in change from baseline in HbA(1c) were -0.7% (-8 mmol/mol) with empagliflozin 10 mg or 25 mg (both pempagliflozin 10 mg and 25 mg, respectively (both pempagliflozin 10 mg (p=0.021) and -2.1 mmHg with empagliflozin 25 mg (p=0.029). Sensitivity analyses provided consistent results for HbA1c and weight, but showed no significant difference between empagliflozin and placebo in change from baseline in SBP. Adverse events (AEs) were reported in 81.7%, 82.0% and 81.3% of patients on empagliflozin 10 mg, 25 mg and placebo, respectively. Confirmed hypoglycaemic AEs (glucose ≤3.9 mmol/l and/or requiring assistance) were reported in 23.7%, 19.4% and 15.6% of patients on empagliflozin 10 mg, 25 mg and placebo, respectively; one patient each on empagliflozin 10mg and placebo required assistance. In conclusion, empagliflozin as add-on to metformin plus sulphonylurea for 76 weeks was well tolerated and led to sustained reductions in HbA1c and weight versus placebo.

    OBJECTIVE To investigate the efficacy and tolerability of empagliflozin as add-on to metformin and sulfonylurea in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS Patients inadequately controlled on metformin and sulfonylurea (HbA1c ≥7 to ≤10%) were randomized and treated with once-daily empagliflozin 10 mg (n = 225), empagliflozin 25 mg (n = 216), or placebo (n = 225) for 24 weeks. The primary end point was change from baseline in HbA1c at week 24. Key secondary end points were changes from baseline in weight and mean daily glucose (MDG) at week 24. RESULTS At week 24, adjusted mean (SE) changes from baseline in HbA1c were −0.17% (0.05) for placebo vs. −0.82% (0.05) and −0.77% (0.05) for empagliflozin 10 and 25 mg, respectively (both P Empagliflozin significantly reduced MDG, weight, and systolic (but not diastolic) blood pressure versus placebo. Adverse events were reported in 62.7, 67.9, and 64.1% of patients on placebo and empagliflozin 10 and 25 mg, respectively. Events consistent with urinary tract infection were reported in 8.0, 10.3, and 8.3% of patients on placebo and empagliflozin 10 and 25 mg, respectively (females: 13.3, 18.0, and 17.5%, respectively; males: 2.7, 2.7, and 0%, respectively). Events consistent with genital infection were reported in 0.9, 2.7, and 2.3% of patients on placebo and empagliflozin 10 and 25 mg, respectively (females: 0.9, 4.5, and 3.9%, respectively; males: 0.9% in each group). CONCLUSIONS Empagliflozin 10 and 25 mg for 24 weeks as add-on to metformin plus sulfonylurea improved glycemic control, weight, and systolic blood pressure and were well tolerated. PMID:23963895

    To evaluate whether template-based structured reports (SRs) add clinical value to primary CT staging in patients with diffuse large B-cell lymphoma (DLBCL) compared to free-text reports (FTRs). In this two-centre study SRs and FTRs were acquired for 16 CT examinations. Thirty-two reports were independently scored by four haematologists using a questionnaire addressing completeness of information, structure, guidance for patient management and overall quality. The questionnaire included yes-no, 10-point Likert scale and 5-point scale questions. Altogether 128 completed questionnaires were evaluated. Non-parametric Wilcoxon signed-rank test and McNemar's test were used for statistical analysis. SRs contained information on affected organs more often than FTRs (95 % vs. 66 %). More SRs commented on extranodal involvement (91 % vs. 62 %). Sufficient information for Ann-Arbor classification was included in more SRs (89 % vs. 64 %). Information extraction was quicker from SRs (median rating on 10-point Likert scale=9 vs. 6; 7-10 vs. 4-8 interquartile range). SRs had better comprehensibility (9 vs. 7; 8-10 vs. 5-8). Contribution of SRs to clinical decision-making was higher (9 vs. 6; 6-10 vs. 3-8). SRs were of higher quality (p < 0.001). All haematologists preferred SRs over FTRs. Structured reporting of CT examinations for primary staging in patients with DLBCL adds clinical value compared to FTRs by increasing completeness of reports, facilitating information extraction and improving patient management. • Structured reporting in CT helps clinicians to assess patients with lymphoma. • This two-centre study showed that structured reporting improves information content and extraction. • Patient management may be improved by structured reporting. • Clinicians preferred structured reports over free-text reports.

    In clinical trials, only about 60% of subjects report an excellent response to intranasal steroids, suggesting a need to add therapies to intranasal steroids to provide additional efficacy. To determine whether the combination of fluticasone furoate and oxymetazoline is more efficacious than either agent alone, and to determine whether rhinitis medicamentosa develops after treatment. We performed a double-blind, double-dummy, randomized, placebo-controlled parallel study. Sixty patients with perennial allergy were randomized to 4 weeks of once-a-night treatment with fluticasone furoate, oxymetazoline hydrochloride, the combination, or placebo. They were monitored during treatment and for 2 weeks posttreatment. The total nasal symptom score over the 4 weeks of treatment was lower with the combination (median, 143; range, 30-316) compared with treatment with placebo (262; 116-358) and oxymetazoline alone (219; 78-385; ANOVA, P = .04). When acoustic rhinometry was compared between the groups at the end of 4 weeks of treatment, the combination resulted in significantly higher nasal volume (mean + SEM, 15.8 + 1.1 mL; Poxymetazoline (12.4 + 0.8 mL) alone. The quality of life data showed no significant differences among the groups. Peak flow showed a nonsignificant improvement with the groups on fluticasone furoate. There was no evidence of rhinitis medicamentosa. The addition of oxymetazoline adds to the effectiveness of fluticasone furoate in the treatment of perennial allergic rhinitis. The lack of development of rhinitis medicamentosa suggests the need for a large multicenter study to develop a once-a-day combination of an intranasal steroid and a long-acting topical decongestant.

    Full Text Available Filtration in a turbo machinery system such as a gas turbine will ensure that the air entering the inlet is free from contaminants that could bring damage to the main system. Self-cleaning filter systems for gas turbines are designed for continuously efficient flow filtration. A good filter would be able to maintain its effectiveness over a longer time period, prolonging the duration between filter replacements and providing lower pressure drop over its operating lifetime. With this goal in mind, the current study is focused on the difference in pressure loss of the benchmark Salutary Avenue Self-cleaning filter in comparison to a new design with an add-on filter cap. Geometry for the add-on filter cap will be based from Salutary Avenue Manufacturing Sdn.Bhd. SOLIDWORKS software was used to model the geometry of the filter, while simulation analysis on the flow through the filter was done using Computational Fluid Dynamic (CFD software. The simulations are based on a low velocity condition, in which the parameter for the inlet velocity are set at 0.032 m/s, 0.063 m/s, 0.094 m/s and 0.126 m/s respectively. From the simulation data obtained for the inlet velocities considered, the pressure drop reduction of the modified filter compared to the benchmark was found to be between 7.59% and 30.18%. All in all, the modification of the filter cap produced a lower pressure drop in comparison with the benchmark filter; an improvement of 27.02% for the total pressure drop was obtained.

    To investigate the joint role of the 48-base pair repeat polymorphism of the dopamine receptor 4 gene (DRD4) and environmental factors in body mass variation among an ethnically diverse sample of U.S. adolescents and young adults. Approximately 2600 adolescent and young adults in the National Longitudinal Study of Adolescent Health (Add Health) who provided DNA measures and measures of height and weight were included in the analysis. Mixed regression modeling was used to investigate the effects of the 7R/7R and any5R variants in the DRD4 gene simultaneously with the effects of physical activity (PA), sedentary behavior (SB), and family socioeconomic status (SES) on body mass variation. European Americans, African Americans, and Hispanic Americans were modeled separately. Both the 7R/7R and any5R genotypes of the DRD4 gene were associated with age- and sex-specific BMI percentile score (BMI-P) based on the Centers for Disease Control and Prevention/National Center for Health Statistics 2000 reference curves among African Americans and only among African Americans (N = 413) 20 years old or younger. Neither genetic variants are associated with the BMI measure among white (N = 1386) and Hispanic-American (N = 331) adolescents. The presence of the 7R/7R genotype was associated with a reduction of 15.1 in BMI percentile (p = 0.005), and the presence of any5R was associated with an increase of 15.5 in BMI percentile (p = 0.003), after adjusting for PA, SB, and family SES. Neither PA nor SB as measured in Add Health is importantly associated with BMI-P, suggesting a complex relationship between body mass and PA/SB among adolescents and young adults. Family SES is negatively related to BMI-P in the European-American sample.

    The objective was to compare the effects of ad libitum consumption of commonly consumed meal-time beverages on energy and fluid intakes and post-meal average subjective appetite and blood glucose in healthy adults. In a randomized controlled design, 29 males and females consumed to satiation an ad libitum pizza meal with one of five beverages in unlimited amount including water (0 kcal), 1% milk (44 kcal/100 ml), regular cola (44 kcal/100 ml), orange juice (44 kcal/100 ml) and diet cola (0 kcal). Food and fluid intakes were measured at the meal. Average subjective appetite and blood glucose were measured before and for 2h after the meal. Although energy intake from pizza was similar among all beverage treatments, the amount of fluid consumed (g) varied among the beverages with intake of orange juice higher than regular and diet cola, but not different from water or milk. Meal-time ingestion of caloric beverages, milk, orange juice and regular cola, led to higher total meal-time energy intakes compared to either water or diet cola. Post-meal blood glucose area under the curve (AUC) was lower after milk than after meals with water, orange juice and regular cola and post-meal average subjective appetite AUC was lower after milk than after meals with water. Meal intakes of nutrients including protein, calcium, phosphorus, zinc, vitamins B12, A and D were higher at the meal with milk compared to the other beverages. Thus, caloric beverages consumed ad libitum during a meal add to total meal-time energy intake, but 1% milk favors a lower post-meal blood glucose and average subjective appetite score and adds to nutrient intake.

    Studies in adults and adolescents have demonstrated that tiotropium is efficacious as an add-on therapy to inhaled corticosteroids (ICSs) with or without other maintenance therapies in patients with moderate or severe symptomatic asthma. We sought to assess the efficacy and safety of once-daily tiotropium Respimat add-on therapy to high-dose ICS with 1 or more controller medications, or medium-dose ICS with 2 or more controller medications, in the first phase III trial of tiotropium in children with severe symptomatic asthma. In this 12-week, double-blind, placebo-controlled, parallel-group trial, 401 participants aged 6 to 11 years were randomized to receive once-daily tiotropium 5 μg (2 puffs of 2.5 μg) or 2.5 μg (2 puffs of 1.25 μg), or placebo (2 puffs), administered through the Respimat device as add-on to background therapy. Compared with placebo, tiotropium 5 μg, but not 2.5 μg, add-on therapy improved the primary end point, peak FEV 1 within 3 hours after dosing (5 μg, 139 mL [95% CI, 75-203; P add-on therapy to ICS with other maintenance therapies in children with severe symptomatic asthma.

    The mini LHC Lego project launched in March (see here) now has almost 6,000 supporters - well on its way to the 10,000 votes needed for it to (hopefully!) hit store shelves. This week, the project added a new feature to its line: a mini control centre! The new LEGO Control centre, featuring operators "Kerstin" and "Marco".   The mini LHC project is the brainchild of ATLAS PhD student Nathan Readioff, who designed Lego replicas of the LHC and the ALICE, ATLAS, CMS and LHCb experiments on a micro scale. Each detector model is small enough to fit in the palm of your hand but crammed with detailed internal systems revealed by cutaway walls. Every major detector component is represented by a Lego piece. Now, Nathan has created a control centre to complement the mini LHC project. This would be an add-on feature for Lego’s consideration, should they decide to develop the accelerator into a box set. “The control centre is ...

    Full Text Available In this poster the author presents the results of a study on several pieces of ashlar masonry were recently discovered in a locale called S'Iscia 'e Su Puttu, indicating the likely presence of sacred place belonging to the Nuragic - Bronze and Early Iron Age - phase. It is located very close to the site of S'Adde 'e S'Ulumu, where an important hoard of bronze objects was found, once considered to belong to a single individual for the absence of any clear archaeological context. This hoard acquires a new dimension thanks to the new data presented here: it could have reasonably been part of a set of ritual activities carried out in a sacred area formed of buildings and spaces between them, a common pattern in Sardinian communities during the Early Iron phase. This poster was presented at the Workshop Materiali e contesti dell'Età del Ferro sarda (Materials and contexts in the Sardinian Iron Age, organised by the University of Glasgow and the Comune di San Vero Milis on the 25th of May 2012, and supported for by the Royal Society of Edinburgh, the Comune di San Vero Milis, the University of Glasgow and the Carnegie Trust of the Universities of Scotland.

    In non-dialysis chronic kidney disease (CKD) patients with dyslipidemia, statin therapy is recommended to prevent cardiovascular complications. Dyslipidemia has been also shown to be an independent risk factor for the progression of CKD. However, it is still unclear whether statin therapy exerts an inhibitory effect on renal deterioration in CKD patients with dyslipidemia. The purpose of the present study was to examine possible therapeutic effects of statin add-on therapy on renal function as well as parameters of lipid and glucose metabolism, arterial stiffness and oxidative stress, in comparison to diet therapy, in CKD patients with dyslipidemia. This study was a randomized, open-label, and parallel-group trial consisted of a 12-months treatment period in non-dialysis CKD patients with alubuminuria and dyslipidemia. Twenty eight patients were randomly assigned either to receive diet counseling alone (diet therapy group) or diet counseling plus pitavastatin (diet-plus-statin therapy group), to achieve the LDL-cholesterol (LDL-C) target of dyslipidemia.

  14. How social learning adds up to a culture: from birdsong to human public opinion.

    2017-01-01

    Distributed social learning may occur at many temporal and spatial scales, but it rarely adds up to a stable culture. Cultures vary in stability and diversity (polymorphism), ranging from chaotic or drifting cultures, through cumulative polymorphic cultures, to stable monolithic cultures with high conformity levels. What features can sustain polymorphism, preventing cultures from collapsing into either chaotic or highly conforming states? We investigate this question by integrating studies across two quite separate disciplines: the emergence of song cultures in birds, and the spread of public opinion and social conventions in humans. In songbirds, the learning process has been studied in great detail, while in human studies the structure of social networks has been experimentally manipulated on large scales. In both cases, the manner in which communication signals are compressed and filtered - either during learning or while traveling through the social network - can affect culture polymorphism and stability. We suggest a simple mechanism of a shifting balance between converging and diverging social forces to explain these effects. Understanding social forces that shape cultural evolution might be useful for designing agile communication systems, which are stable and polymorphic enough to promote gradual changes in institutional behavior. © 2017.

    Obesity has been associated with kidney disease in adults. This study was designed to evaluate the association of obesity with an early marker of kidney disease, albuminuria, among young adults. Urinalysis (n = 9371), albumin-to-creatinine ratio (n = 4463), and body mass index (kg/m2) were measured in the Add Health Wave III cohort (2001 to 2002), a multiethnic sample of young adults followed for approximately 6 yr. Multivariate logistic regression modeled the association of sex-specific albuminuria with body mass index, adjusted for sample weights, sex, race, ethnicity, and glycosuria. Urinalysis revealed that 0.8% had proteinuria, 4.6% had hematuria, 0.2% had combined hematuria and proteinuria, and 1.5% had glycosuria. Albuminuria prevalence was 4.4%. Mean body mass index was higher among those with albuminuria compared with those without. There were no associations between body mass index categories of 25 to or = 35 kg/m2) was associated with albuminuria, compared with the lowest category (OR = 1.76, 95% CI: 1.02 to 3.04). Glycosuria (OR = 4.0; 95% CI: 1.5 to 11.1, p adults is particularly concerning. Obesity may be a target for primary prevention of kidney and cardiovascular disease.

    Full Text Available Adjustable compliant actuators are being designed and implemented in robotic devices because of their ability to minimize large forces due to impacts, to safely interact with the user, and to store and release energy in passive elastic elements. Conceived as a new force-controlled compliant actuator, an adjustable rigidity with embedded sensor and locking mechanism actuator (ARES-XL is presented in this paper. This compliant system is intended to be implemented in a gait exoskeleton for children with neuro muscular diseases (NMDs to exploit the intrinsic dynamics during locomotion. This paper describes the mechanics and initial evaluation of the ARES-XL, a novel variable impedance actuator (VIA that allows the implementation of an add-on locking mechanism to this system, and in combination with its zero stiffness capability and large deflection range, provides this novel joint with improved properties when compared to previous prototypes developed by the authors and other state-of-the-art (SoA devices. The evaluation of the system proves how this design exceeds the main capabilities of a previous prototype as well as providing versatile actuation that could lead to its implementation in multiple joints.

    Full Text Available Companies are always trying to differentiate themselves from the rest of the pack by applying different strategies such as improving customer service, increasing the efficiency of their operations, or reducing their costs. Most of the time, however, these goals are competing against each other for scarce resources, and managers often need to decide to concentrate on one. A small company can effectively and simultaneously accomplish these goals for a fraction of the cost by implementing communications-enabled business processes or solutions, which are a set of technology components that add real-time networking functionality to applications. One particular implementation of this framework is the one provided by Coral CEA. Coral CEA is a business ecosystem anchored around CEA functionalities that are offered as building blocks, out-of-the-box components that link the capabilities and intelligence of networks platforms with the power of current applications to provide a new set of features and functionalities. In this article, we show how a small company called Rezact, located in the ski resort town of Mont-Tremblant, Quebec, successfully implemented CEA capabilities within its own operations using Coral CEA services.

    Studies defining role of systemic steroids in routine management of cervical lymph node tuberculosis (CLNTB) are too few and inconclusive. The present study was carried out to define the role of add-on prednisolone in the management of CLNTB. Patients of CLNTB were randomized into two groups. Group I patients received DOTS Category I treatment along with prednisolone 1mg/kg for first 4 weeks and then tapered down. Group II patients received DOTS Category I treatment along with placebo. Patients were kept under close follow up for 6 months. Response to therapy and adverse drug reactions, if any, were recorded. A total of 120 patients completed the study protocol. The two groups were similar with respect to age, sex, smoking, alcoholism, and clinical profile (p>0.5). At 2 months, 54 out of 60 patients in Group I showed symptom relief when compared with 44 out of 60 patients in Group II (plymph node/s were noted in 3 and 13 patients in Group I and Group II, respectively (p0.05). All the adverse reactions were transient and amenable to symptomatic treatment. Copyright © 2015 Tuberculosis Association of India. Published by Elsevier B.V. All rights reserved.

    2011-09-01

    To examine prevalence and correlates (gender, Body Mass Index) of disordered eating in American Indian/Native American (AI/NA) and white young adults. We examined data from the 10,334 participants (mean age 21.93 years, SD = 1.8) of the National Longitudinal Study of Adolescent Health (ADD Health) Wave III for gender differences among AI/NA participants (236 women, 253 men) and ethnic group differences on measures of eating pathology. Among AI/NA groups, women were significantly more likely than men to report loss of control and embarrassment due to overeating. In gender-stratified analyses, a significantly higher prevalence of AI/NA women reported disordered eating behaviors compared with white women; there were no between group differences in prevalence for breakfast skipping or having been diagnosed with an eating disorder. Among men, disordered eating behaviors were uncommon and no comparison was statistically significant. Our study offers a first glimpse into the problem of eating pathology among AI/NA individuals. Gender differences among AI/NA participants are similar to results reported in white samples. That AI/NA women were as likely as white women to have been diagnosed with an eating disorder is striking in light of well documented under-utilization of mental health care among AI/NA individuals.

    2015-01-01

    The aim of the present observational study was to determine the effects of a delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) oromucosal spray (Sativex(®) spray), brand name Sativex(®), indicated for drug-resistant MS spasticity, on the driving ability of treated MS patients. The study was conducted over a period of 4-6 weeks. Thirty-three MS patients with moderate to severe treatment-resistant spasticity and planned to begin add-on treatment with Sativex(®) were enrolled at three specialized MS centres in Germany. A set of five driving test procedures from a validated computerized test battery was used to evaluate the driving ability of eligible patients. Tests were performed by patients at baseline and repeated after 4-6 weeks of treatment with Sativex(®) oromucosal spray. According to German normative data, the test thresholds achieved by the general population served as a reference to allow for a fitness/unfitness to drive classification. Patients showed comparable driving test results at baseline and at final visits. Only two patients changed classification shifting from 'unfit' to drive to 'fit' and vice versa. The mean severity of spasticity, as self-reported by the patients, improved with statistical significance. Sativex(®) was generally well tolerated. Treatment of MS patients with Sativex(®) does not negatively impact on driving ability and may improve moderate to severe treatment-resistant MS spasticity. © 2014 John Wiley & Sons A/S.

    van der Zee, Ymie J; Stiers, Peter; Evenhuis, Heleen M

    To determine whether the assessment of visual acuity ratios might improve the referral of children with (sub)normal visual acuity but at risk of cerebral visual impairment. In an exploratory study, we assessed visual acuity, crowding ratio and the ratios between grating acuity (Teller Acuity Cards-II) and optotype acuity (Cambridge Crowding Cards) in 60 typically developing school children (mean age 5y8m±1y1m), 21 children with ocular abnormalities only (5y7m±1y9m) and 26 children with (suspected) brain damage (5y7m±1y11m). Sensitivities and specificities were calculated for targets and controls from the perspective of different groups of diagnosticians: youth health care professionals (target: children with any visual abnormalities), ophthalmologists and low vision experts (target: children at risk of cerebral visual impairment). For youth health care professionals subnormal visual acuity had the best sensitivity (76%) and specificity (70%). For ophthalmologists and low vision experts the crowding ratio had the best sensitivity (67%) and specificity (79 and 86%). Youth health care professionals best continue applying subnormal visual acuity for screening, whereas ophthalmologists and low vision experts best add the crowding ratio to their routine diagnostics, to distinguish children at risk of visual impairment in the context of brain damage from children with ocular pathology only.

    1996-08-01

    Petreleos de Venezuela (PDVSA) and its affiliated companies, aware of the importance of the technology to sustain the viability of a successful corporation in global markets with increasing competition and stringent economies, are devoting important efforts in technology as an effective tool to add competitiveness to its core businesses. These efforts are based in the conception of the technology as a structural aspect of the corporation integrated to each one of its businesses. In this sense technology is considered in an integrated way together with markets, operations, infrastructure, resources, etc., across the value chain of the company, from the conception of its vision and mission to the formulation and execution of its operating plans. In this presentation, the conceptual and methodological aspects employed by PDVSA in the establishment of its technology strategy integrated to its business plan, and subsequent project portfolio definition, are summarized. The experience acquired through this corporative exercise conducted by PDVSA confirms that technology and its management are highly linked to the culture of the companies and of the countries where they operate. The technology management best practices are very helpful in establishing processes and specific methodologies; however, the consideration of other aspects such as leadership, management style, shared values, etc., need to be taken into account with the same emphasis, in order to accomplish the changes needed to create a technology culture fitted to a given setting and ideology.

    The aim of the present exploratory clinical study was to evaluate LD as an add-on therapy for treating nightmares. Thirty-two subjects having nightmares (ICD-10: F51.5) at least twice a week participated. Subjects were randomly assigned to group: A) Gestalt therapy group (= GTG), or B) Gestalt and lucid dreaming group therapy (= LDG). Each group lasted ten weeks. Participants kept a sleep/dream diary over the treatment. Examinations with respect to nightmare frequency and sleep quality (Pittsburgh Sleep Quality Index) were carried out at the beginning, after five and ten weeks and at a follow-up three months later. Concerning nightmare frequency, a significant reduction was found in both groups after the ten-week-study and at the follow-up (Wilcoxon test: P ≤ 0.05). Significant reduction in dream recall frequency could only be observed in the GTG (Wilcoxon test: P ≤ 0.05). For subjects having succeeded in learning lucid dreaming, reduction was sooner and higher. Sleep quality improved for both groups at the follow-up (P ≤ 0.05, Wilcoxon test). Only the LDG showed significant improvement at the end of therapy (P ≤ 0.05). Lucid dreaming, in combination with Gestalt therapy, is a potent technique to reduce nightmare frequency and improve the subjective quality of sleep. © 2015 John Wiley & Sons A/S.

    Mozart's Sonata for two pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart effect. Our previous work revealed that epileptiform discharges in children with epilepsy decreased during and immediately after listening to Mozart K.448. In this study, we evaluated the long-term effects of Mozart K.448 on children with refractory epilepsy. Eleven children with refractory epilepsy were enrolled. All of the patients were diagnosed as having had refractory epilepsy for more than 1 year (range =1 year to 6 years 4 months, mean =3 years 11 months) and had been receiving at least two antiepileptic drugs (AED). During the study period, they listened to Mozart K.448 once a day before bedtime for 6 months. Seizure frequencies were recorded 6 months before they started listening to this music and monthly during the study period. All of the patients remained on the same AEDs during the 6-month study period. Frequencies of seizures were compared before and after listening to Mozart K.448. Eight of eleven patients were seizure free (N=2) or had very good responses (N=6) after 6 months of listening to Mozart K.448. The remaining three (27.3%) showed minimal or no effect (effectiveness Mozart K.448 should be further studied as a potential add-on therapy in the treatment of children with refractory epilepsy.

    We examined whether memantine add-on to antipsychotic treatment is beneficial in schizophrenia treatment. This systematic review and meta-analysis aimed to achieve stronger evidence on the efficacy and safety of memantine add-on for treating schizophrenia. We analyzed double-blind, randomized, placebo-controlled trials of memantine add-on treatment in schizophrenia patients receiving antipsychotics. The primary outcomes were amelioration of negative symptoms and all-cause discontinuation. Dichotomous outcomes are presented as risk ratios (RRs), and continuous outcomes are presented as mean differences (MDs) or standardized mean differences (SMDs). Eight studies (n = 448) were included. Although memantine add-on treatment was superior to placebo for ameliorating negative symptoms (SMD = -0.96, p = 0.006, I 2  = 88%; N = 7, n = 367) in the Positive and Negative Syndrome Scale general subscale (MD = -1.62, p = 0.002, I 2  = 0%; N = 4, n = 151) and Mini-Mental Status Examination score (MD = -3.07, p add-on treatment remained superior to placebo (SMD = -1.29, p = 0.00001). Meta-regression analysis showed that patient age was associated with memantine-associated amelioration of negative symptoms (slope = 0.171, p = 0.0206). Memantine add-on treatment may be beneficial for treating psychopathological symptoms (especially negative symptoms) in schizophrenia patients. The negative-symptom effect size may be associated with younger adult schizophrenia patients.

    This paper investigates the performance of star-ring hybrid topology networks with optical add and drop multiplexer (OADM) in dense wavelength division multiplexing (DWDM) system with 0.8 nm channel spacing at different bit rates (5, 10 and 15 Gbps) in terms of bit error rate (BER), quality factor and optical signal-to-noise ratio (OSNR). OADM has the capability to add and drop the new channels and provides the wavelength routing between star and ring topologies. It is observed that the hybrid topology supports 128 users on upper and lower ends with 150 km distance between the nodes of ring network without dispersion compensating fiber.

  15. Value Creation in the Maritime Chain of Transportation

    DEFF Research Database (Denmark)

    Roslyng Olesen, Thomas

    This report has examined the concept of value creation in the maritime chain of transportation. A maritime transport chain can best be conceptualized as a network through which carriers (e.g. shipping companies and haulage providers) and third parties (e.g. terminal operators, freight forwarders......, brokers and agents) provide services for the movement of cargo provided by shippers. The main actors in the maritime chain of transportation are the carriers who add value to the shipper by moving goods from areas with excess supply to areas with excess demand. In this process a number of (independent...... transactions between the actors in the chain. A port agent may add value to a carrier by securing smooth port operations and thus reduce waiting time. The added value may, however, be captured by a freight forwarder who forces the carrier to lower the price or more likely be distributed among several actors...

  16. Panel presentation: LDC rate design and transportation issues

    International Nuclear Information System (INIS)

    Patrick, T.M.

    1992-01-01

    This paper covers four general views about local distributing company (LDC) sales rate design, transportation issues, and their implications for policy makers. LDC sales rates often hinder marketing to price sensitive customers. LDC rate design contributes to this problem, but there are other major causes such as add-on revenue taxes and pipeline take-or-pay charges that add to customer costs. State commissions, in varying degrees, are constrained in their ability to respond to a number of the barriers to improved gas marketing. Some problems are simply beyond the power of state commissions to remedy. These include federally imposed pipeline rate structures and take-or-pay costs, as well as various limits imposed by state legislatures (e.g., shut-off prohibitions, add-on taxes). Where they are feasible, LDC transportation services can mitigate marketing barriers that impede sales services. Customers select and pay for only their desired level of supply reliability and flexibility from sellers and pipeline transporters, as well as desired levels of standby service from the LDC. While it greatly benefits markets, the provision of transportation service by an LDC creates important new issues. One is fairness in allocating LDC resources between the sales and transportation functions and in pricing them, to avoid subsidies of one service by the other

    2012-04-01

    Intravenous urography (IVU) combined with add-on CT (IVU-CT) can help to provide more diagnostic information for determining the localization and nature of ureteral abnormalities with less irradiation dose. This study aimed to determine the value of IVU-CT for diagnosis of ureteral diseases, where IVU is insufficient to determine the diagnosis. Two hundred and eighty patients underwent IVU for suspected ureteral disorders, which identified a definite diagnosis in 184 cases and was insufficient for definite diagnosis in 96 cases designated as indeterminate diagnosis. Subsequently 90 patients (six patients declined CT) with indeterminate diagnosis consented to undergo immediate or delayed helical CT scan. The CT data were transferred to the workstation for post-processing, and the cost and mean effective dose for each imaging method were calculated and compared indirectly. Of the 90 indeterminate diagnosis cases, diagnosis was determined in 86 cases by IVU-CT with a diagnostic accordance rate of 95.6%, while 184/280 (65.7%) had diagnosis determined by IVU alone. There was a significant difference between IVU and IVU-CT in the determination of the diagnosis of ureteral diseases (c(2) = 36.4, P IVU equals to 1/8 - 1/9 of that for CT urography (CTU), and the cost of IVU-CT is as much as 1/3 of CTU. CTU results in the highest mean effective dose, approximately nine times that for IVU and three times that for IVU-CT. IVU-CT provides valuable information for the localization and diagnosis of ureteral abnormalities and may be considered as an efficient, cost-effective and low-dose diagnostic technique in this setting.

    Full text: Aim: to assess the possible incremental value of a functional perfusion/metabolism (P/M) image in epilepsy patients, as the uncoupling of perfusion and metabolism has been suggested to be useful in localising the seizure focus. (Eur J Med Mol Imaging 2008;35:579-588) Methods: Forty patients with intractable epilepsy being considered for neurosurgery had EEG telemetry, MRI, ictal and interictal ECD SPECT and FOG PET. Nuclear Medicine evaluation included ictal-interictal subtraction and 3D-SSP functional images. Final diagnosis for the purpose of this study was based on surgical outcome or a combination of seizure semiology. EEG and the results of all investigations. The P/M image was produced by spatially registering interictal ECO SPECT and resolution corrected FDG PET images to the patient's MRI. Each study was normalized using whole brain counts and then the corrected ECD count was divided by the corrected FOG count in each voxel. The functional image was scaled for viewing and P/M measured to assess its accuracy in comparison with routine assessment. Results: Eighteen patients had suspected temporal and 22 extratemporal epilepsy. The forty patients were divided into 3 groups: 8 had previous brain surgery (lobectomy in 6), 18 had lesions on MRI and 14 had non lesional epilepsy. Review of the functional P/M images in all 3 groups showed no patient with a perfusion metabolism mismatch at a site that was normal or equivocal on routine SPECT and PET assessment. Conclusion: P/M ratio functional images do not add additional information for localising the epileptic focus.

    In this study of the project DyAdd (Adult Dyslexia and Attention Deficit Disorder in Finland), classical eyeblink conditioning (EBC) was investigated in both delay and trace paradigms in adults (18-55 years) with dyslexia (n = 37), attention deficit-hyperactivity disorder (ADHD; n = 21), their comorbid combination (n = 8), and healthy controls (n = 35). In addition, the profiles of three participants with a rare autosomal dominant cerebellar disease were assessed (episodic ataxia type 2, EA-2). We found that participants with dyslexia were overall slower learners than controls in eyeblink conditioning. Further, they were the only group that had a reduced number of CRs in mediotemporal-dependent trace paradigm compared to the more cerebellum-dependent delay paradigm. Second, ADHD was found to be related to larger CR amplitude. Third, those with a comorbid condition learned faster and manifested CRs that were not well timed. Fourth, the cerebellar patients showed nearly no conditioning at all. Correlations between EBC and various neuropsychological domains (phonological processing, reading, spelling, arithmetic, executive functions, attention, and fine motor control) over all participants resulted in significant relations only for the delay paradigm: Increased amount of reading errors related with later peak latency and increased amount of self-corrections in fine motor control related with larger response magnitude. Within those who conditioned, relations emerged only for the trace paradigm: better spelling was related to larger response magnitude. These results do not lend support to the cerebellar hypothesis of dyslexia. On the contrary, dyslexia in its pure form seems to be related to a relative dysfunction of a larger hippocampal-cerebellar network. Further, larger responses in the ADHD group are suggested to result from their lowered responding threshold.

  20. Add-on effect of probucol in atherosclerotic, cholesterol-fed rabbits treated with atorvastatin.

    Directory of Open Access Journals (Sweden)

    Yuka Keyamura

    Full Text Available OBJECTIVE: Lowering the blood concentration of low-density lipoprotein (LDL cholesterol is the primary strategy employed in treating atherosclerotic disorders; however, most commonly prescribed statins prevent cardiovascular events in just 30% to 40% of treated patients. Therefore, additional treatment is required for patients in whom statins have been ineffective. In this study of atherosclerosis in rabbits, we examined the effect of probucol, a lipid-lowering drug with potent antioxidative effects, added to treatment with atorvastatin. METHODS AND RESULTS: Atherosclerosis was induced by feeding rabbits chow containing 0.5% cholesterol for 8 weeks. Probucol 0.1%, atorvastatin 0.001%, and atorvastatin 0.003% were administered solely or in combination for 6 weeks, beginning 2 weeks after the start of atherosclerosis induction. Atorvastatin decreased the plasma concentration of non-high-density lipoprotein cholesterol (non-HDLC dose-dependently; atorvastatin 0.003% decreased the plasma concentration of non-HDLC by 25% and the area of atherosclerotic lesions by 21%. Probucol decreased the plasma concentration of non-HDLC to the same extent as atorvastatin (i.e., by 22% and the area of atherosclerotic lesions by 41%. Probucol with 0.003% atorvastatin decreased the plasma concentration of non-HDLC by 38% and the area of atherosclerotic lesions by 61%. Co-administration of probucol with atorvastatin did not affect the antioxidative effects of probucol, which were not evident on treatment with atorvastatin alone, such as prevention of in vitro LDL-oxidation, increase in paraoxonase-1 activity of HDL, and decreases in plasma and plaque levels of oxidized-LDL in vivo. CONCLUSIONS: Probucol has significant add-on anti-atherosclerotic effects when combined with atorvastatin treatment; suggesting that this combination might be beneficial for treatment of atherosclerosis.

    2010-01-01

    We theoretically simulate and experimentally demonstrate ultra-large through-port extinctions in silicon-based asymmetrically-coupled add-drop microring resonators (MRs). Through-port responses in an add-drop MR are analyzed by simulations and large extinctions are found when the MR is near-critically coupled. Accurate fabrication techniques are applied in producing a series of 20 μm-radii add-drop microrings with drop-side gap-widths in slight differences. A through-port extinction of about 42.7 dB is measured in an MR with through- and drop-side gap-width to be respectively 280nm and 295nm. The large extinction suggests about a 20.5 dB improvement from the symmetrical add-drop MR of the same size and the through-side gap-width. The experimental results are finally compared with the post-fabrication simulations, which show a gap-width tolerance of > 30 am for the through-port extinction enhancement

    Full Text Available CFD simulations using ANSYS FLUENT 6.3.26 have been performed on a generic SUV design and the settings are validated using the experimental results investigated by Khalighi. Moreover, an add-on inspired by the concept presented by Englar at GTRI for drag reduction has been designed and added to the generic SUV design. CFD results of add-on model and the basic SUV model have been compared for a number of aerodynamic parameters. Also drag coefficient, drag force, mean surface pressure, mean velocities, and Cp values at different locations in the wake have been compared for both models. The main objective of the study is to present a new add-on device which may be used on SUVs for increasing the fuel efficiency of the vehicle. Mean pressure results show an increase in the total base pressure on the SUV after using the device. An overall reduction of 8% in the aerodynamic drag coefficient on the add-on SUV has been investigated analytically in this study.

Eslicarbazepine acetate (ESL) is licensed as an add-on therapy for POS and has a favorable tolerability profile. To investigate retention, utilization, reported efficacy, safety and tolerability as well as effects on health-related quality of life using ESL as an add-on treatment to an established monotherapy in a real-world adult population with POS in Germany. A subgroup analysis was performed on the data derived from the German study sites that had participated in an international, non-interventional, open-label study conducted in eight European countries (eslicarbazepine acetate in partial-onset seizures, EPOS). Adult patients with POS whose physician had decided to prescribe add-on treatment with ESL to an established monotherapy were followed over a total period of approximately six months (three visits: baseline and after periods of approximately three and six months). Data collection included patient retention, reported efficacy, safety and tolerability as well as quality of life (QOLIE-10). The subgroup analysis included 104 patients which had been enrolled at 38 German study sites. After 6 months, retention of ESL add-on therapy was 86.5 %, with 44.7 % of patients reporting seizure freedom over the 3 months prior to this visit. The overall tolerability of ESL add-on therapy was favorable: 32 adverse events (AE) were reported in 20 patients (19.2 %), while only two events in two patients were considered serious. No new safety signals were detected.

    Full Text Available The aim of this review was to identify the effectiveness of therapies added on to conventional exercise training to maximise exercise capacity in patients with chronic obstructive pulmonary disease (COPD. Electronic databases were searched, identifying trials comparing exercise training with exercise training plus “add-on” therapy. Outcomes included peak oxygen uptake (V′O2peak, work rate and incremental/endurance cycle and field walking tests. Individual trial effects on exercise capacity were extracted and collated into eight subgroups and pooled for meta-analysis. Sensitivity analyses were conducted to explore the stability of effect estimates across studies employing patient-centred designs and those deemed to be of “high” quality (PEDro score >5 out of 10. 74 studies (2506 subjects met review inclusion criteria. Interventions spanned a broad scope of clinical practice and were most commonly evaluated via the 6-min walking distance and V′O2peak. Meta-analysis revealed few clinically relevant and statistically significant benefits of “add-on” therapies on exercise performance compared with exercise training. Benefits favouring “add-on” therapies were observed across six different interventions (additional exercise training, noninvasive ventilation, bronchodilator therapy, growth hormone, vitamin D and nutritional supplementation. The sensitivity analyses included considerably fewer studies, but revealed minimal differences to the primary analysis. The lack of systematic benefits of “add-on” interventions is a probable reflection of methodological limitations, such as “one size fits all” eligibility criteria, that are inherent in many of the included studies of “add-on” therapies. Future clarification regarding the exact value of such therapies may only arise from adequately powered, multicentre clinical trials of tailored interventions for carefully selected COPD patient subgroups defined according to distinct

  13. Interfacility transports.

    Financial pressures exerted by managed care organizations toward hospitals to improve efficiencies and to lower total healthcare costs continue to force physicians and administrators to reevaluate operations and practices. This shifting of risk exposure from insurers to providers has resulted in many mergers, acquisitions, and affiliations, so as to form integrated health systems that reduce repetition and duplication of services. Therefore, as these integrated systems develop, along with the emergence of tertiary care, regional referral, and specialty hospitals, the need for patient transfers between such facilities will expand. The decision to move patients between facilities is a multicomponent process comprising health, safety, financial, and legal concerns. Interfacility transportation of patients has been performed over the past 20 to 30 years. Whereas ground transport services were prominent in the 1970s, air medical programs using helicopters and fixed-wing aircraft have recently become widespread. Both hospital-based and private agencies have continued to develop programs for efficiently and expeditiously transporting critically ill or injured patients, many requiring complex life-support devices. The Practice Management Committee of the American College of Emergency Physicians recently updated the 1990 policy statement on interfacility transfers, and two position statements are available from the National Association of EMS Physicians on criteria for air medical transport and medical direction for interfacility transport services. This review provides an overview of transportation systems and services available and assists physicians in understanding the various modes and characteristics of systems available. Personnel configurations and capabilities, physiological limitations, inherent requirements for equipment and patient preparation, and legal issues involved with transferring patients are also outlined.

  14. Global Land Transport Infrastructure Requirements

    Over the next four decades, global passenger and freight travel is expected to double over 2010 levels. In order to accommodate this growth, it is expected that the world will need to add nearly 25 million paved road lane-kilometres and 335 000 rail track kilometres. In addition, it is expected that between 45 000 square kilometres and 77 000 square kilometres of new parking spaces will be added to accommodate vehicle stock growth. These land transport infrastructure additions, when combined with operations, maintenance and repairs, are expected to cost as much as USD 45 trillion by 2050. This publication reports on the International Energy Agency’s (IEA) analysis of infrastructure requirements to support projected road and rail travel through 2050, using the IEA Mobility Model. It considers land transport infrastructure additions to support travel growth to 2050. It also considers potential savings if countries pursue “avoid and shift” policies: in this scenario, cumulative global land transport infrastructure spending could decrease as much as USD 20 trillion by 2050 over baseline projections.

    Dopamine agonists (DA) are often used as first-line monotherapy for the symptomatic control of Parkinson's disease (PD). However, DA monotherapy typically becomes inadequate within a few years, at which time the DA dosage must be increased or other antiparkinsonian medications added. Adding a monoamine oxidase-B (MAO-B) inhibitor to DA monotherapy might improve symptomatic control while maintaining good safety and tolerability. We conducted an 18-week, randomized, double-blind, placebo-controlled trial of rasagiline 1 mg/d as an add-on to DA therapy (ropinirole ≥ 6 mg/d or pramipexole ≥ 1.0 mg/d) in early PD patients whose conditions were not adequately controlled on their current treatment regimen. The primary efficacy variable was the change in total Unified Parkinson Disease Rating Scale (UPDRS) score (sum of parts I, II, and III) from baseline to week 18, comparing rasagiline and placebo groups. The modified intent-to-treat (ITT) population included 321 subjects whose mean ± SD age was 62.6 ± 9.7, and duration of PD was 2.1 ± 2.1 years. Results demonstrated a significantly greater improvement in total UPDRS scores from baseline to week 18 in the rasagiline group compared with the placebo group (least squares [LS] mean difference ± SE, -2.4 ± 0.95; 95% confidence interval [CI], -4.3, -0.5; P = 0.012). Mean improvement (LS mean ± SE) was -3.6 ± 0.68 in the rasagiline group and -1.2 ± 0.68 in the placebo group. Rasagiline was well tolerated, and the most common adverse events (AEs; rasagiline vs. placebo) were dizziness (7.4% vs. 6.1%), somnolence (6.8% vs. 6.7%), and headache (6.2% vs. 4.3%). Rasagiline 1 mg/d provided statistically significant improvement when added to dopamine agonist therapy and was well tolerated. © 2014 International Parkinson and Movement Disorder Society.

    Our clinical experience with low dose loxapine (5-15 mg/day) suggests promising efficacy and safety for irritability in autism spectrum disorders (ASD). We studied low dose loxapine prospectively in adolescents and adults with ASD and irritability. Additionally, we measured loxapine and metabolite concentrations, and brain-derived neurotrophic factor (BDNF) as a biomarker of neuromodulation. We performed a 12 week open trial of add-on loxapine in subjects, ages 13-65 years, diagnosed with ASD, and Aberrant Behavior Checklist-Irritability (ABC-I) subscale scores >14. Loxapine was dosed flexibly up to 15 mg daily, starting with 5 mg on alternate days. From weeks 1 to 6, other psychoactive medications were tapered if possible; from weeks 6 to 12, all medication doses were held stable. The primary outcome was the Clinical Global Impressions-Improvement subscale (CGI-I), ratings of Much Improved or Very Much Improved. Secondary outcomes were the ABC-I, Repetitive Behavior Scale-Revised, and Schalock Quality of Life scale. Serum BDNF and loxapine and metabolite concentrations were assayed. BDNF rs6265 was genotyped. Sixteen subjects were enrolled; 12 completed all visits. Median age was 18 years (range 13-39). Median final loxapine dose was 7.5 mg/day (2.5-15). All 14 subjects (100%) with data at week 12 were rated as Much Improved on CGI-I at 12 weeks. Mean change on ABC-I at 12 weeks was -31%, p=0.01. Mean body mass index (BMI)-Z decreased between weeks 6 and 12, p=0.03. Side effects were minimal, and prolactin elevation occurred in only one subject. BDNF concentrations measured in 11 subjects increased significantly (p=0.04). Subjects with AG genotype for BDNF rs6265 required a lower dose of loxapine at study end, but had similar behavioral and BDNF concentration changes as the GG genotype. Low dose loxapine shows promise as a repurposed drug for irritability in ASD. Loxapine effects on BDNF warrant further study.

  17. Insights from a national survey into why substance abuse treatment units add prevention and outreach services

    Full Text Available Abstract Background Previous studies have found that even limited prevention-related interventions can affect health behaviors such as substance use and risky sex. Substance abuse treatment providers are ideal candidates to provide these services, but typically have little or no financial incentive to do so. The purpose of this study was therefore to explore why some substance abuse treatment units have added new prevention and outreach services. Based on an ecological framework of organizational strategy, three categories of predictors were tested: (1 environmental, (2 unit-level, and (3 unit leadership. Results A lagged cross-sectional logistic model of 450 outpatient substance abuse treatment units revealed that local per capita income, mental health center affiliation, and clinical supervisors' graduate degrees were positively associated with likelihood of adding prevention-related education and outreach services. Managed care contracts and methadone treatment were negatively associated with addition of these services. No hospital-affiliated agencies added prevention and outreach services during the study period. Conclusion Findings supported the study's ecological perspective on organizational strategy, with factors at environmental, unit, and unit leadership levels associated with additions of prevention and outreach services. Among the significant predictors, ties to managed care payers and unit leadership graduate education emerge as potential leverage points for public policy. In the current sample, units with managed care contracts were less likely to add prevention and outreach services. This is not surprising, given managed care's emphasis on cost control. However, the association with this payment source suggests that public managed care programs might affects prevention and outreach differently through revised incentives. Specifically, government payers could explicitly compensate substance abuse treatment units in managed care

    Jasmonates are oxygenated lipids (oxylipins) that control defense gene expression in response to cell damage in plants. How mobile are these potent mediators within tissues? Exploiting a series of 13-lipoxygenase (13-lox) mutants in Arabidopsis (Arabidopsis thaliana) that displays impaired jasmonic acid (JA) synthesis in specific cell types and using JA-inducible reporters, we mapped the extent of the transport of endogenous jasmonates across the plant vegetative growth phase. In seedlings, we found that jasmonate (or JA precursors) could translocate axially from wounded shoots to unwounded roots in a LOX2-dependent manner. Grafting experiments with the wild type and JA-deficient mutants confirmed shoot-to-root oxylipin transport. Next, we used rosettes to investigate radial cell-to-cell transport of jasmonates. After finding that the LOX6 protein localized to xylem contact cells was not wound inducible, we used the lox234 triple mutant to genetically isolate LOX6 as the only JA precursor-producing LOX in the plant. When a leaf of this mutant was wounded, the JA reporter gene was expressed in distal leaves. Leaf sectioning showed that JA reporter expression extended from contact cells throughout the vascular bundle and into extravascular cells, revealing a radial movement of jasmonates. Our results add a crucial element to a growing picture of how the distal wound response is regulated in rosettes, showing that both axial (shoot-to-root) and radial (cell-to-cell) transport of oxylipins plays a major role in the wound response. The strategies developed herein provide unique tools with which to identify intercellular jasmonate transport routes. © 2015 American Society of Plant Biologists. All Rights Reserved.

    The energy, environmental and social benefits of sustainable transportation, i.e, public transit, biking and walking, have long been recognized but are now mainstream in global and local transportation policy debates. However, the economic value of sustainable transportation has always been seen as secondary, unless many external costs were included. The results of a new global study show that cities with significant sustainable transportation systems have reduced costs on road construction and maintenance; better operating cost recovery and fuel-efficiency; fewer road accidents and less air pollution. In overall terms, the percentage of city funds going to transportation is reduced. The data show that cities with the most roads have the highest transportation costs and the most rail-oriented cities have the lowest. Further, the most sprawling cities have the highest direct and indirect costs for transportation. Thus, strategies to contain sprawl, to reurbanize, to build new rail systems info car-dependent suburbs with focussed sub-centers, and to facilitate biking and walking, not only will improve energy efficiency but will reduce costs to the economy of a city. Strategies that build freeways and add to sprawl will do the opposite. Trends indicate that moves toward sustainable urban patterns are beginning. The need to operationalize sustainable transportation strategies in planning and engineering practice and in the politics of infrastructure funding remains a major challenge. Some cities are showing how this can be done. (author)

    2012, 72 of these resulted in additions to the BGS NLD and 4 in amendments to previously collected information. This raises the total number of landslides reported in 2012 from 186 to 258. Using the increased presence of landslides in the news and social media, 2012 had already resulted in the largest number of landslides for a given year being recorded by BGS in the NLD. With the additions from this current study to the NLD, we estimate that the annual total number of landslides was around six times higher in 2012 than the average annual total between 2006 and 2011. Years prior to 2012 plan to be revisited using this method, and more broadly, this method of searching newspaper archives could be applied to many other natural hazards to add richness to databases of historical events and improve our understanding of hazard occurrence and impact.

    A silicon-based on-chip reconfigurable optical add-drop multiplexer (ROADM) is presented for hybrid wavelength-division-multiplexing-mode-division-multiplexing systems. The present ROADM consists of a four-channel mode demultiplexer, four wavelength-selective thermo-optic switches based on microring resonators, and a four-channel mode multiplexer. With the present ROADM, one can add/drop one of wavelength channels of any mode to/from the multimode bus waveguide successfully with an excess loss of 2-5 dB and an extinction ratio of ∼20  dB over a wavelength range of 1525-1555 nm.

    2017-02-01

    In this paper, we introduce an idea of content-adaptive sparse reconstruction to achieve optimized magnification quality for those down sampled video frames, to which two stages of pruning are applied to select the closest correlated images for construction of an over-complete dictionary and drive the sparse representation of its enlarged frame. In this way, not only the sampling and dictionary training process is accelerated and optimized in accordance with the input frame content, but also an add-on video compression codec can be further developed by applying such scheme as a preprocessor to any standard video compression algorithm. Our extensive experiments illustrate that (i) the proposed content-adaptive sparse reconstruction outperforms the existing benchmark in terms of super-resolution quality; (ii) When applied to H.264, one of the international video compression standards, the proposed add-on video codec can achieve three times more compression while maintaining competitive decoding quality.

    The transport of discarded electronic and electrical appliances (e-waste) to developing regions has received considerable attention, but it is difficult to assess the significance of this issue without a quantitative understanding of the amounts involved. The main objective of this study is to track the global transport of e-wastes by compiling and constraining existing estimates of the amount of e-waste generated domestically in each country MGEN, exported from countries belonging to the Organization for Economic Cooperation and Development (OECD) MEXP, and imported in countries outside of the OECD MIMP. Reference year is 2005 and all estimates are given with an uncertainty range. Estimates of MGEN obtained by apportioning a global total of ∼ 35,000 kt (range 20,000-50,000 kt) based on a nation's gross domestic product agree well with independent estimates of MGEN for individual countries. Import estimates MIMP to the countries believed to be the major recipients of e-waste exports from the OECD globally (China, India, and five West African countries) suggests that ∼ 5,000 kt (3,600 kt-7,300 kt) may have been imported annually to these non-OECD countries alone, which represents ∼ 23% (17%-34%) of the amounts of e-waste generated domestically within the OECD. MEXP for each OECD country is then estimated by applying this fraction of 23% to its MGEN. By allocating each country's MGEN, MIMP, MEXP and MNET = MGEN + MIMP - MEXP, we can map the global generation and flows of e-waste from OECD to non-OECD countries. While significant uncertainties remain, we note that estimated import into seven non-OECD countries alone are often at the higher end of estimates of exports from OECD countries.

    Full Text Available Background: With the emergence of obesity as a global health issue, an increasing number of major demographic surveys are collecting measured anthropometric data. Yet little is known about the characteristics and reliability of these data. Objective: We evaluate the accuracy and reliability of anthropometric data collected in the home during Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health, compare our estimates to national standard, clinic-based estimates from the National Health and Nutrition Examination Survey (NHANES and, using both sources, provide a detailed anthropometric description of young adults in the United States. Methods: The reliability of Add Health in-home anthropometric measures was estimated from repeat examinations of a random subsample of study participants. A digit preference analysis evaluated the quality of anthropometric data recorded by field interviewers. The adjusted odds of obesity and central obesity in Add Health vs. NHANES were estimated with logistic regression. Results: Short-term reliabilities of in-home measures of height, weight, waist and arm circumference - as well as derived body mass index (BMI, kg/m2 - were excellent. Prevalence of obesity (37Š vs. 29Š and central obesity (47Š vs. 38Š was higher in Add Health than in NHANES, while socio-demographic patterns of obesity and central obesity were comparable in the two studies. Conclusions: Properly trained non-medical field interviewers can collect reliable anthropometric data in a nationwide, home visit study. This national cohort of young adults in the United States faces a high risk of early-onset chronic disease and premature mortality.

    Full Text Available Abstract Background The renin-angiotensin-aldosterone system (RAAS plays an important role in the progression of chronic kidney disease (CKD. Although dual RAAS inhibition results in worse renal outcomes than monotherapy in high risk type 2 diabetes patients, the effect of dual RAAS inhibition in patients with non-DM CKD is unclear. The aim of this study was to evaluate the potential renoprotective effect of add-on direct renin inhibitor in non-DM CKD patients. Methods We retrospectively enrolled 189 non-DM CKD patients who had been taking angiotensin II receptor blockers (ARBs for more than six months. Patients were divided into an add-on aliskiren group and an ARB monotherapy group. The primary outcomes were a decline in glomerular filtration rate (GFR and a reduction in urinary protein-to-creatinine ratio at six months. Results The baseline characteristics of the two groups were similar. Aliskiren 150 mg daily reduced the urinary protein-to-creatinine ratio by 26% (95% confidence interval, 15 to 37%; p  Conclusion Add-on direct renin inhibitor aliskiren (150 mg daily safely reduced proteinuria and attenuated the decline in GFR in the non-DM CKD patients who were receiving ARBs.

    Here we provide a detailed description of the genome-wide information available on the National Longitudinal Study of Adolescent to Adult Health (Add Health) sibling pair subsample (Harris et al. in Twin Res Hum Genet 16:391-398, 2013). A total of 2,020 samples were genotyped (including duplicates) arising from 1946 Add Health individuals from the sibling pairs subsample. After various steps for quality control (QC) and quality assurance (QA), we have high quality genome-wide data available on 1,888 individuals. In this report, we first highlight the QC and QA steps that were taken to prune the data of poorly performing samples and genetic markers. We further estimate the pairwise biological relationships using genome-wide data and compare those estimates to the assumed relationships in Add Health. Additionally, using genome-wide data from known regional reference populations from Europe, West Africa, North and South America, Japan and China, we estimate the relative genetic ancestry of the respondents. Finally, rather than conducting a traditional cross-sectional genome-wide association study (GWAS) of body mass index (BMI), we opted to utilize the extensive publicly available genome-wide information to conduct a weighted GWAS of longitudinal BMI while accounting for both family and ethnic variation.

    In adult humans, the net absorption of dietary copper is approximately 1 mg/d. Dietary copper joins some 4-5 mg of endogenous copper flowing into the gastrointestinal tract through various digestive juices. Most of this copper returns to the circulation and to the tissues (including liver) that formed them. Much lower amounts of copper flow into and out of other major parts of the body (including heart, skeletal muscle, and brain). Newly absorbed copper is transported to body tissues in two phases, borne primarily by plasma protein carriers (albumin, transcuprein, and ceruloplasmin). In the first phase, copper goes from the intestine to the liver and kidney; in the second phase, copper usually goes from the liver (and perhaps also the kidney) to other organs. Ceruloplasmin plays a role in this second phase. Alternatively, liver copper can also exit via the bile, and in a form that is less easily reabsorbed. Copper is also present in and transported by other body fluids, including those bathing the brain and central nervous system and surrounding the fetus in the amniotic sac. Ceruloplasmin is present in these fluids and may also be involved in copper transport there. The concentrations of copper and ceruloplasmin in milk vary with lactational stage. Parallel changes occur in ceruloplasmin messenger RNA expression in the mammary gland (as determined in pigs). Copper in milk ceruloplasmin appears to be particularly available for absorption, at least in rats.

    Conclusion: This exploratory observational study suggests reduction of mortality and morbidity with add-on homoeopathic medicine. Further randomized controlled trial study with comparable groups is desirable. If findings are confirmed by subsequent research, add-on Homoeopathy might have relevant implication for its management.

No local laser is needed since the wavelength- and modulation format transparent 'add' is accomplished by using optical switches, delay lines and the 'dropped' input. Applications are found in flexible,

    This paper summarizes discrete fracture network (DFN) analysis of the Tracer Retention Understanding Experiments 'TRUE-1' carried out at the Aespoe Hard Rock Laboratory in Sweden from 1995 through 2000. These studies confirmed the ability of the DFN approach, together with conventional advection-dispersion-diffusion assumptions to calibrate and predict solute transport in a single fracture at the 5 to 10 meter scale. The analysis also indicated the possibility that alternative formulations of reactive transport constitutive laws may also be useful. In addition to addressing issues of ADD transport, the 'TRUE-1' experiment raised and addressed important issues regarding solute transport pathways and the effect of fracture network connectivity on flow and transport in fractured rock

  1. Add-drop double bus microresonator array local oscillators for sharp multiple Fano resonance engineering

    Li, Jiahua; Qu, Ye; Wu, Ying

    2018-03-01

    Asymmetric resonances are currently the subject of considerable research efforts in photonic nanostructures. Here we propose a feasible method to achieve multiple Fano resonances and their control in an optical compound system consisting of an array of on-chip microresonators without mutual coupling and two parallel fiber waveguides side-coupled to the microresonator array by means of a local oscillator. We derive analytical and transparent expressions for the power transmission function summing over the two light transporting paths within the framework of quantum optics. It is clearly shown that introducing the local oscillator as an additional light propagating path plays an important role in the formation of narrow and multiple Fano resonance lineshapes. The power transmission spectrum through the combination of both the microresonator array and the local oscillator is very sensitive to the system parameters, for example, the intrinsic decay rate of the resonator, the phase shift factor of the local oscillator, the transmission coefficient of the fiber beam splitter, and the total number of the microresonators. Through detailed analysis, we identify the optimums for generating Fano resonance lineshapes. Also, we assess the experimental feasibility of the scheme using currently available technology. The proposed method is relatively straightforward as it requires only one local oscillator as one interferometer arm and it is mostly fiber-based. We believe that our work will help to understand and improve multiple Fano resonance engineering.

    Endometriosis affects over 10 million women in the United States. Depot leuprolide acetate (LA), a gonadotropin-releasing hormone agonist, has been used extensively for the treatment of women with endometriosis but is associated with hypoestrogenic symptoms and bone mineral density loss. The concomitant use of add-back therapies, specifically norethindrone acetate (NETA), can alleviate these adverse effects. To compare adherence to and persistence with LA treatment and time to endometriosis-related surgery among women treated with NETA and women treated with LA plus other add-back therapies or LA only. This retrospective analysis was conducted using Truven Health MarketScan Commercial Claims and Encounters Database. Women with a diagnosis of endometriosis (ICD-9-CM code 617.xx) who initiated LA (index date) in 2005-2011 were selected for inclusion. Additional requirements were 12 months of continuous enrollment pre- and post-index and no evidence of endometriosis-related surgeries pre-index or up to 30 days post-index; no pre-index use of estrogen or noncontraceptive hormones; and no diagnoses of uterine fibroids, malignant neoplasms, infertility, or pregnancy. Patients were characterized as using NETA; other add-back therapies (estrogens, progestins, or estrogen-progestin combinations); or no add-back therapy. Adherence to and persistence with LA were measured over the 6 months following the index date using outpatient medical and pharmacy claims. Patients were considered adherent if their proportion of days covered was greater than or equal to 0.80. Persistence was operationalized as time to discontinuation, defined as a continuous gap of > 60 days without LA on hand. Time to endometriosis-related surgery (laparotomy, laparoscopy, excision/ablation/fulguration, oophorectomy, and hysterectomy) was measured over the 12 months following the index date. Surgeries were identified from inpatient and outpatient medical claims using procedure codes. Outcomes were

    2001-01-01

    The transport of protons across membranes is an essential process for both bioenergetics of modern cells and the origins of cellular life. All living systems make use of proton gradients across cell walls to convert environmental energy into a high-energy chemical compound, adenosine triphosphate (ATP), synthesized from adenosine diphosphate. ATP, in turn, is used as a source of energy to drive many cellular reactions. The ubiquity of this process in biology suggests that even the earliest cellular systems were relying on proton gradient for harvesting environmental energy needed to support their survival and growth. In contemporary cells, proton transfer is assisted by large, complex proteins embedded in membranes. The issue addressed in this Study was: how the same process can be accomplished with the aid of similar but much simpler molecules that could have existed in the protobiological milieu? The model system used in the study contained a bilayer membrane made of phospholipid, dimyristoylphosphatidylcholine (DMPC) which is a good model of the biological membranes forming cellular boundaries. Both sides of the bilayer were surrounded by water which simulated the environment inside and outside the cell. Embedded in the membrane was a fragment of the Influenza-A M$_2$ protein and enough sodium counterions to maintain system neutrality. This protein has been shown to exhibit remarkably high rates of proton transport and, therefore, is an excellent model to study the formation of proton gradients across membranes. The Influenza M$_2$ protein is 97 amino acids in length, but a fragment 25 amino acids long. which contains a transmembrane domain of 19 amino acids flanked by three amino acids on each side. is sufficient to transport protons. Four identical protein fragments, each folded into a helix, aggregate to form small channels spanning the membrane. Protons are conducted through a narrow pore in the middle of the channel in response to applied voltage. This

    Full Text Available Despite recent advances in implantable cardioverter defibrillator (ICD technology, the long-term reliability of ICD leads remains a significant problem. Lead failures constitute a major risk for patients with an implantable cardioverter defibrillator. There is no clear consensus on treatment strategy of ICD lead failure and decision should be individualized. We report a pacing-dependent elderly male with ICD lead pacing failure secondary to insulation break resulting in recurrent syncope. We emphasize the technique of “Add-on pacing lead implantation” could be an effective and alternative to ICD lead replacement.

  6. Usage of OpenStack Virtual Machine and MATLAB HPC Add-on leads to faster turnaround

    2017-03-16

    We need to run hundreds of MATLAB® simulations while changing the parameters between each simulation. These simulations need to be run sequentially, and the parameters are defined manually from one simulation to the next. This makes this type of workload unsuitable for a shared cluster. For this reason we are using a cluster running in an OpenStack® Virtual Machine and are using the MATLAB HPC Add-on for submitting jobs to the cluster. As a result we are now able to have a turnaround time for the simulations of the order of a few hours, instead of the 24 hours needed on a local workstation.

    Gerber, F; Galli Carminati, G

    2013-08-01

    The lack of psychometric measures of psychopathology especially in intellectual disabilities (ID) population was addressed by creation of the Psychiatric Assessment Schedule for Adult with Developmental Disability (PAS-ADD-10) in Moss et al. This schedule is a structured interview designed for professionals in psychopathology. The PAS-ADD Checklist was created as a screening tool designed for non-specialists in mental illness, such as families and care staff. The Checklist includes 29 symptoms items graded on a four-point scale. When the score passes the threshold, this indicates the need for further psychiatric assessment. In a study by Moss et al. and a replication by Sturmey et al., the PAS-ADD Checklist was validated and proved reliable as a screening tool for psychiatric disorders in a population of adults with ID. In this study, the French translation of the Checklist is compared with the English version and the psychometric properties are presented for outpatients. The French version was created by translation and back translation. Acceptability, internal consistency, inter-rater reliability, factorial analysis and sensitivity/specificity were calculated. Reliability analyses for sub-scales and threshold scales showed good (Cronbach's alpha coefficient greater than 0.7) to acceptable (alpha over 0.6) internal consistency. Cronbach's alpha was over 0.8 when the total scale was considered. Spearman Rank correlations, calculated for 45 pairs of raters on threshold scores, are above 0.66, which is a good sign of accordance between non-specialist raters. Sensitivity and specificity were computed for the number of participants who did and did not cross threshold and for whom a psychiatric disorder was or was not present. The sensitivity was 55% and specificity was 70%. The confirmatory factor analysis with a three-factor solution explained only 46.1%, which suggests a mediocre fit of the data to the model. Even if items have good saturation on each factor, it does

    We investigated whether diffusion-weighted Imaging (DWI) adds diagnostic confidence in assessing focal liver lesions (FLLs). By reviewing FLLs without and with DWI at 1.5 T, two radiologists scored the confidence in diagnosing benignancy/malignancy (confidence score), and DWI usefulness (usefulness score). We showed that adding DWI significantly decreased the confidence score of the most experienced radiologist and increased his confidence in false-negative diagnoses showing atypical features on conventional magnetic resonance imaging.

    Multi-wavelength generation system using an optical spin within the modified add-drop optical filter known as a PANDA ring resonator for molecular transport network security is proposed. By using the dark-bright soliton pair control, the optical capsules can be constructed and applied to securely transport the trapped molecules within the network. The advantage is that the dark and bright soliton pair (components) can securely propagate for long distance without electromagnetic interference. In operation, the optical intensity from PANDA ring resonator is fed into gold nano-antenna, where the surface plasmon oscillation between soliton pair and metallic waveguide is established.

    The aetiology of latent autoimmune diabetes in adults (LADA), assessed by autoimmune markers, is insufficiently clarified. We cross-sectionally investigated the prevalence and prospectively the prediabetic and postdiabetic presence of antibodies to glutamic acid decarboxylase (GADA), insulinoma-associated protein 2 and zinc transporter 8 in LADA and in type 1 diabetes. We included 208 'classic' type 1, 161 LADA and 302 type 2 diabetic cases from the second (HUNT2: 1995–1997) and third (HUNT3: 2006–2008) Nord-Trøndelag health surveys. Prospective data were available for 59 type 1, 44 LADA and 302 type 2 diabetic cases followed from HUNT2 to HUNT3. From HUNT3, 24 type 1 diabetic and 31 LADA incident cases were available. Cross-sectionally, 90% of LADA cases were positive for only one antibody (10% multiple-antibodypositive). Prospectively, 59% of GADA-positive LADA patients in HUNT2 were no longer positive in HUNT3. LADA patients who became negative possessed less frequently risk HLA haplotypes and were phenotypically more akin to those with type 2 diabetes than to those who stayed positive. Still, those losing positivity differed from those with type 2 diabetes by lower C-peptide levels (p = 0.009). Of incident LADA cases in HUNT3, 64% were already antibody-positive in HUNT2, i.e. before diabetes diagnosis. These incident LADA cases were phenotypically more akin to type 1 diabetes than were those who did not display positivity in HUNT2. The pattern of antibodies, the postdiabetic loss or persistence as well as the prediabetic absence or presence of antibodies influence LADA phenotypes. Time-dependent presence or absence of antibodies adds new modalities to the heterogeneity of LADA.

    Full Text Available Abstract This is a report on a 37-patient continuation study of the open ended, Omega-3 Fatty Acid (O-3FA add-on study. Subjects consisted of the original 19 patients, along with 18 new patients recruited and followed in the same fashion as the first nineteen. Subjects carried a DSM-IV-TR diagnosis of Bipolar Disorder and were visiting a Mood Disorder Clinic regularly through the length of the study. At each visit, patients' clinical status was monitored using the Clinical Monitoring Form. Subjects reported on the frequency and severity of irritability experienced during the preceding ten days; frequency was measured by way of percentage of days in which subjects experienced irritability, while severity of that irritability was rated on a Likert scale of 1 – 4 (if present. The irritability component of Young Mania Rating Scale (YMRS was also recorded quarterly on 13 of the 39 patients consistently. Patients had persistent irritability despite their ongoing pharmacologic and psychotherapy. Omega-3 Fatty Acid intake helped with the irritability component of patients suffering from bipolar disorder with a significant presenting sign of irritability. Low dose (1 to 2 grams per day, add-on O-3FA may also help with the irritability component of different clinical conditions, such as schizophrenia, borderline personality disorder and other psychiatric conditions with a common presenting sign of irritability.

    2010-02-01

    Australians currently consume too much salt causing adverse consequences for health. The media play an important role in the provision of nutrition advice to consumers. Previous research shows that many foods advertized in consumer magazines are high in salt, but little research has examined magazine recipes in this context. The aim of this project was to summarize directions for salt use in recipes in leading Australian magazines. In August 2007 and 2008, the top 10 magazines by circulation that included at least five recipes, were examined. Standardized information was collected about directions for salt use in recipes. Three hundred and thirty recipes were identified in 2007 and 417 in 2008. About 68% of recipes included high-salt ingredients, 37% instructed to season with salt, 10% instructed to add a specific quantity of salt and 15% recommended selection of low-salt ingredients. There was substantial variability in directions for salt use in recipes between magazines, but no clear differences between 2007 and 2008. Many recipes advised to add salt in direct contradiction to national dietary guidelines. There is clear potential for editorial guidelines on salt use in recipes to play a role in advancing public health efforts in Australia and other such nations.

  17. Pubertal Stress and Nutrition and their Association with Sexual Orientation and Height in the Add Health Data.

    2017-01-01

    A number of studies have indicated that gay men tend to be shorter, on average, than heterosexual men. Less evidence exists that lesbian women are taller, on average, than heterosexual women. The most popular explanation of the association between sexual orientation and height involves prenatal factors, such that, for example, gay men may have been exposed to lower than typical androgens during fetal development, which impacts their height and sexual orientation as adults. An alternative explanation involves stress, given that stress has been associated with sexual minority identification and with lower height. Another alternative explanation involves nutrition, although its relationship is less clear with sexual minority identification. Using the Add Health data, which is a large, nationally representative and longitudinal sample of American adolescents (n = 14,786), we tested a mediation model, such that sexual orientation → pubertal stress/nutrition → height. Within men, we found that gay men (n = 126) were shorter, on average, than heterosexual men (n = 6412). None of the 24 pubertal stress-related and 15 pubertal nutrition-related variables assessed in the Add Health data mediated the relationship between sexual orientation and height in men. Within women, lesbians (n = 75) did not differ significantly in stature compared to heterosexual women (n = 6267). Thus, prenatal mechanisms (e.g., hormones, maternal immune response) are likely better candidates for explaining the height difference between gay men and heterosexual men.

    2014-01-01

    Full Text Available The occurrence of epileptic seizures in the presence of hepatic disease is not uncommon in clinical practice. Selecting an appropriate AED for patients affected by liver failure who have new-onset epileptic seizures can be challenging. We describe a 64-year-old man affected by liver cirrhosis. The patient developed partial epilepsy with secondary generalization because of an intracerebral hemorrhage in the left parieto-occipital regions. After the neurosurgery procedure, seizures reappeared and were initially managed with levetiracetam. After one month, the patient experienced clusters of seizures while on stable treatment with levetiracetam. Pregabalin as add-on was not tolerated; therefore, he received a low dose of phenobarbital as add-on treatment. The patient developed hepatic encephalopathy. Phenobarbital was immediately stopped, and oral lacosamide was added. A rapid recovery of encephalopathy with a 6-month seizure freedom was obtained. The patient died 6 months later because of progressive impairment of liver function. Lacosamide may represent an alternative to other AEDs in patients with liver failure; however, further prospective evaluation of its efficacy and safety in this clinical setting is needed.

  19. Beam transport

    International Nuclear Information System (INIS)

    1988-01-01

    Considerable experience has now been gained with the various beam transport lines, and a number of minor changes have been made to improve the ease of operation. These include: replacement of certain little-used slits by profile monitors (harps or scanners); relocation of steering magnets, closer to diagnostic harps or profile scanners; installation of a scanner inside the isocentric neutron therapy system; and conversion of a 2-doublet quadrupole telescope (on the neutron therapy beamline) to a 2-triplet telescope. The beam-swinger project has been delayed by very late delivery of the magnet iron to the manufacturer, but is now progressing smoothly. The K=600 spectrometer magnets have now been delivered and are being assembled for field mapping. The x,y-table with its associated mapping equipment is complete, together with the driver software. One of the experimental areas has been dedicated to the production of collimated neutron beams and has been equipped with a bending magnet and beam dump, together with steel collimators fixed at 4 degrees intervals from 0 degrees to 16 degrees. Changes to the target cooling and shielding system for isotope production have led to a request for much smaller beam spot sizes on target, and preparations have been made for rearrangement of the isotope beamline to permit installation of quadrupole triplets on the three beamlines after the switching magnet. A practical system of quadrupoles for matching beam properties to the spectrometer has been designed. 6 figs

    2017-05-01

    In bacteria, double-strand break (DSB) repair via homologous recombination is thought to be initiated through the bi-directional degradation and resection of DNA ends by a helicase-nuclease complex such as AddAB. The activity of AddAB has been well-studied in vitro, with translocation speeds between 400-2000 bp/s on linear DNA suggesting that a large section of DNA around a break site is processed for repair. However, the translocation rate and activity of AddAB in vivo is not known, and how AddAB is regulated to prevent excessive DNA degradation around a break site is unclear. To examine the functions and mechanistic regulation of AddAB inside bacterial cells, we developed a next-generation sequencing-based approach to assay DNA processing after a site-specific DSB was introduced on the chromosome of Caulobacter crescentus. Using this assay we determined the in vivo rates of DSB processing by AddAB and found that putative chi sites attenuate processing in a RecA-dependent manner. This RecA-mediated regulation of AddAB prevents the excessive loss of DNA around a break site, limiting the effects of DSB processing on transcription. In sum, our results, taken together with prior studies, support a mechanism for regulating AddAB that couples two key events of DSB repair-the attenuation of DNA-end processing and the initiation of homology search by RecA-thereby helping to ensure that genomic integrity is maintained during DSB repair.

In plants, transporters thus function as gatekeepers between the plant and its surrounding environment and between organs......, tissues, cells and intracellular compartments. Since plants are highly compartmentalized organisms with complex transportation infrastructures, they consequently have many transporters. However, the vast majority of predicted transporters have not yet been experimentally verified to have transport...... activity.

    Mutations in the ATRX protein are associated with the alpha-thalassemia and mental retardation X-linked syndrome (ATR-X). Almost half of the disease-causing mutations occur in its ATRX-Dnmt3-Dnmt3L (ADD) domain. By employing peptide arrays, chromatin pull-down and peptide binding assays, we show specific binding of the ADD domain to H3 histone tail peptides containing H3K9me3. Peptide binding was disrupted by the presence of the H3K4me3 and H3K4me2 modification marks indicating that the ATRX-ADD domain has a combined readout of these two important marks (absence of H3K4me2 and H3K4me3 and presence of H3K9me3). Disease-causing mutations reduced ATRX-ADD binding to H3 tail peptides. ATRX variants, which fail in the H3K9me3 interaction, show a loss of heterochromatic localization in cells, which indicates the chromatin targeting function of the ADD domain of ATRX. Disruption of H3K9me3 binding may be a general pathogenicity pathway of ATRX mutations in the ADD domain which may explain the clustering of disease mutations in this part of the ATRX protein.

    Some patients with depression do not respond to first and second line conventional antidepressants and are therefore characterised as suffering from treatment refractory depression (TRD). On-going psychosocial stress and dysfunction of the hypothalamic-pituitary-adrenal axis are both associated with an attenuated clinical response to antidepressants. Preclinical data shows that co-administration of corticosteroids leads to a reduction in the ability of selective serotonin reuptake inhibitors to increase forebrain 5-hydroxytryptamine, while co-administration of antiglucocorticoids has the opposite effect. A Cochrane review suggests that antiglucocorticoid augmentation of antidepressants may be effective in treating TRD and includes a pilot study of the cortisol synthesis inhibitor, metyrapone. The Antiglucocorticoid augmentation of anti-Depressants in Depression (The ADD Study) is a multicentre randomised placebo controlled trial of metyrapone augmentation of serotonergic antidepressants in a large population of patients with TRD in the UK National Health Service. Patients with moderate to severe treatment refractory Major Depression aged 18 to 65 will be randomised to metyrapone 500 mg twice daily or placebo for three weeks, in addition to on-going conventional serotonergic antidepressants. The primary outcome will be improvement in Montgomery-Åsberg Depression Rating Scale score five weeks after randomisation (i.e. two weeks after trial medication discontinuation). Secondary outcomes will include the degree of persistence of treatment effect for up to 6 months, improvements in quality of life and also safety and tolerability of metyrapone. The ADD Study will also include a range of sub-studies investigating the potential mechanism of action of metyrapone. Strengths of the ADD study include broad inclusion criteria meaning that the sample will be representative of patients with TRD treated within the UK National Health Service, longer follow up, which to our

    Many Free and Open Source Software (FOSS) tools have been created for the various application fields within geoscience. While FOSS allows re-implementation of functionalities in new environments by access to the original codebase, the easiest approach to build new software solutions for new problems is the combination or merging of existing software tools. Such mash-ups are implemented by embedding and encapsulating FOSS tools within each another, effectively focusing the use of the embedded software to the specific role it needs to perform in the given scenario, while ignoring all its other capabilities. GRASS GIS is a powerful and established FOSS GIS for raster, vector and volume data processing while the Generic Mapping Tools (GMT) are a suite of powerful Open Source mapping tools, which exceed the mapping capabilities of GRASS GIS. This poster reports on the new GRASS GIS add-on module r.out.polycones. It enables users to utilize non-continuous projections for map production within the GRASS production environment. This is implemented on the software level by encapsulating a subset of GMT mapping capabilities into a GRASS GIS (Version 6.x) add-on module. The module was developed at the German National Library of Science and Technology (TIB) to provide custom global maps of scientific collaboration networks, such as the DataCite consortium, the registration agency for Digital Object Identifiers (DOI) for research data. The GRASS GIS add-on module can be used for global mapping of raster data into a variety of non continuous sinosoidal projections, allowing the creation of printable biangles (gores) to be used for globe making. Due to the well structured modular nature of GRASS modules, technical follow-up work will focus on API-level Python-based integration in GRASS 7 [1]. Based on this, GMT based mapping capabilities in GRASS will be extended beyond non-continuous sinosoidal maps and advanced from raster-layers to content GRASS display monitors. References

    Surface plasmons polaritons are electromagnetic waves propagating along the surface of a conductor. Surface plasmons photonics is a promising candidate to satisfy the constraints of miniaturization of optical interconnects. This contribution reviews an experimental parametric study of dielectric loaded surface plasmon waveguides ring resonators and add-drop filters within the perspective of the recently suggested hybrid technology merging plasmonic and silicon photonics on a single board (European FP7 project PLATON "Merging Plasmonic and Silicon Photonics Technology towards Tb/s routing in optical interconnects"). Conclusions relevant for dielectric loaded surface plasmon switches to be integrated in silicon photonic circuitry will be drawn. They rely on the opportunity offered by plasmonic circuitry to carry optical signals and electric currents through the same thin metal circuitry. The heating of the dielectric loading by the electric current enables to design low foot-print thermo-optical switches driving the optical signal flow.

    Eosinophils and mast cells are among the key cells in inflammatory diseases like chronic rhinosinusitis (CRS) and asthma. Leukotriene antagonists have proven to be effective in the treatment of asthma, but data about their efficacy in CRS are scarce, whereas data on montelukast as an add-on treatment to intranasal corticosteroids (INCS) in a postoperative setting are completely lacking. Prospective, randomized, open-label trial. In this trial with long-term follow-up, we evaluated the efficacy of montelukast as an add-on treatment to INCS in postoperative CRS with nasal polyp (CRSwNP) patients. CRSwNP patients (N = 72) undergoing endoscopic sinus surgery were randomized in two arms for the postoperative treatment. One group (N = 36) received INCS in monotherapy, whereas the other group (N = 36) received INCS in association with montelukast for 1 year. The efficacy of montelukast with INCS was evaluated by assessing both subjective (total five-symptom score [T5SS]) and objective (nasal polyp score [NPS], Lund-Mackay [LMK] score, and subjective olfactometry [Barcelona Smell Test 24]) outcome parameters and compared with the gold standard of INCS in monotherapy. After 1 year of surgery, T5SS, NPS, and LMK score were significantly reduced in patients treated with either INCS or INCS plus montelukast, without significant differences between the two treatment arms. Improvement of smell loss by olfactometry was also observed with no differences between arms. Similar findings were observed at 3 and 6 months. These results suggest that the addition of montelukast to INCS should not be recommended in the treatment of postoperative CRSwNP patients. 1b Laryngoscope, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    Choledocholithiasis commonly occurs in patients with symptomatic cholelithiasis. Although the recently developed multidetector computed tomography (MDCT) scan enhances the ability to diagnose choledocholithiasis, this technique is considered to have some limitations for evaluating the common bile duct (CBD). The purpose of this study was to evaluate the necessity for performing endoscopic ultrasound (EUS) as an add-on test to detect choledocholithiasis in patients who were diagnosed with gallstone disease without choledocholithiasis based on MDCT. Three hundred twenty patients with gallstone disease and no evidence of CBD stones according to MDCT underwent EUS between March 2006 and April 2011. If CBD stones were suspected based on the EUS results or clinical symptoms, a final diagnosis was obtained by endoscopic retrograde cholangiopancreatography (ERCP). The patients' medical records were retrospectively analyzed based on clinical symptoms, biochemical findings, and results of the imaging studies. CBD stones were not detected with MDCT in 41 (12.8 %) out of 320 patients with gallstone disease. The causes for these discrepancies could be attributed to small stone size (n = 19, 46.3 %), isodensity (n = 18, 43.9 %), impacted stones (n = 1, 2.4 %), and misdiagnosis (n = 3, 7.3 %). If EUS were used as a triage tool, unnecessary diagnostic ERCP and its complications could be avoided for 245 (76.6 %) patients. MDCT may not be a primary technique for detecting CBD stones. EUS should be performed instead as an add-on test to evaluate the CBD for patients with gallstone-related disease. In particular, EUS should be routinely recommended for patients with abnormal liver enzyme levels, pancreatitis, and dilated CBD.

    Full Text Available Purpose: Patients undergoing middle ear surgery experience variable degrees of postoperative nausea and vomiting (PONV despite prophylaxis and treatment with ondansetron or other 5HT 3 receptor antagonists. Furthermore vertigo or dizziness are not well controlled perioperatively. Role of betahistine was tested as an add-on to ondansetron in control of PONV and vertigo in middle ear surgery cases. Materials and Methods: We conducted a prospective, randomized, double-blind, placebo controlled study, enrolling one hundred patients undergoing middle ear surgery under local anesthesia into two groups consisting of fifty (n = 50 patients each. Group A patients were given betahistine 16 mg plus ondansetron 8 mg and placebo plus ondansetron 8 mg were given to group B or placebo group, orally 3 hours before starting operation. The incidence of nausea, vomiting, and dizziness was noted during the intraoperative and postoperative 24 hours period. Chi-square test, unpaired ′t′ test, and Fisher′s exact tests were performed for statistical analysis using SPSS version 16 and Open Epi version 2.3.1 softwares. Results: Complete response was obtained in 90% patients in the betahistine group as compared to 66% in the placebo group. Vomiting in the intraoperative and postoperative period was noted in 4% and 8% cases, respectively, in the betahistine group as compared to 18% and 26%, respectively, in the placebo group. Overall, vertigo was 10% versus 32% in betahistine group and placebo group, respectively. Conclusion: Betahistine as an add-on to ondansetron can significantly attenuate PONV and perioperative vertigo, following middle ear surgeries.

    Allergic rhinitis (AR) with or without conjunctivitis (AR/C) is associated with a significant health and economic burden, and is often accompanied by asthma. Pharmacotherapies are the mainstay treatment options for AR and asthma, but guidelines also recommend allergy immunotherapy (AIT). Unlike pharmacotherapies, AIT has the ability to modify the underlying immunologic mechanisms of AR and asthma with the potential for long-term benefits after treatment is discontinued. Immunotherapy may also prevent progression of AR/C to asthma. Sublingual immunotherapy (SLIT)-tablets are a self-administered alternative to subcutaneous immunotherapy that provide the benefits of AIT without the cost and inconvenience of frequent office visits or the discomfort of injections. SLIT-tablets are also an option that can be utilized by primary care clinicians. Pharmacotherapies are generally effective in mild disease although a number of patients remain uncontrolled. SLIT-tablets have proven efficacy for AR in adults, children, and poly-sensitized allergic patients. Indirect comparisons indicate that SLIT-tablets have superior or comparable efficacy compared with traditional pharmacotherapies for seasonal AR, and superior efficacy for perennial AR. House dust mite (HDM) SLIT-tablets have also demonstrated clinically relevant benefits for asthma, with significant observed reductions in daily inhaled corticosteroid use, risk of asthma exacerbations, and asthma symptoms. SLIT-tablets are well tolerated, with minimal risk of systemic allergic reactions. The most common treatment-related adverse events are oral site reactions such as oral pruritus and throat irritation. Based on the favorable efficacy and safety profile, as well as the convenience of at-home oral administration and disease-modifying effects, SLIT-tablets should be considered as an alternative or add-on treatment to pharmacotherapy for AR/C, and as an add-on treatment for HDM allergic asthma.

    Quetiapine extended release (XR) and lithium are treatments with proven efficacy in acute mania. This randomized study evaluated the efficacy and safety of lithium or placebo as add-on to quetiapine XR in adult patients with manic or mixed symptoms of bipolar I disorder. In this 6-week, double-blind study (Trial D144AC00003), adult patients with DSM-IV-TR-diagnosed bipolar I disorder (current episode manic or mixed), a Young Mania Rating Scale (YMRS) total score ≥20, and score ≥4 on two of four core YMRS items were administered quetiapine XR (400 to 800 mg/day) and randomly assigned to receive add-on lithium (600 to 1,800 mg/day) or placebo. The primary efficacy end point was change in the YMRS total score from baseline to day 43, analyzed using a mixed-model for repeated measures (MMRM) approach. Secondary efficacy and safety end points were also measured. Rating scales were administered by trained staff. Three hundred fifty-six patients treated with quetiapine XR were randomized to add-on lithium (n = 173) or placebo (n = 183). Two hundred ninety-one patients (81.7%) completed the study. At day 43, least squares mean change in YMRS total score was -22.8 for add-on lithium and -20.1 for add-on placebo, a statistically significant treatment group difference of -2.69 (p add-on lithium was associated with significant improvements in response, remission, illness severity, and overall illness versus add-on placebo (p add-on lithium compared with add-on placebo. Lithium in combination with quetiapine XR was generally well tolerated, with a similar profile to quetiapine XR in combination with placebo. The addition of lithium to quetiapine XR therapy was associated with significantly greater efficacy than placebo as add-on and was generally well tolerated in patients with acute bipolar I mania. This study was registered under Clinicaltrials.gov Identifier NCT00931723.

    The aim of this study was to assess the role of add-on devices for the prevention of phlebitis and other complications associated with the use of peripheral catheters. Patients admitted to an infectious diseases ward and requiring the insertion of a peripheral catheter for at least 24h were randomly allocated to be managed with or without add-on devices. Incidence of phlebitis and all complications were the primary outcomes. Extravasation, inadvertent withdrawal, obstruction and rupture were considered to be mechanical complications, and analysis was performed using survival methods. Of 683 evaluated catheters, 351 were allocated to the add-on device arm and 332 to the control arm. Despite randomisation, patients in the add-on device group were older (P=0.048), less likely to have human immunodeficiency virus (P=0.02) and more likely to have received antibiotics (P=0.05). After adjustment for these variables, the hazard ratio for phlebitis remained non-significant (hazard ratio: 0.95; 95% confidence interval: 0.7-1.3), but the risk of mechanical complications became lower in the add-on device arm (0.68; 0.5-0.94). This translated into a trend towards a lower risk of any complication (0.83; 0.67-1.01). The beneficial effect on mechanical or all complications was noticeable after six days of catheterisation. Add-on devices do not reduce the incidence of phlebitis but may prevent mechanical complications. However, the impact of add-on devices on the incidence of all complications is at most small and only apparent after the sixth day of catheter use.

    To compare the effectiveness and cardiovascular safety of long-acting beta-agonists (LABAs) with those of leukotriene receptor antagonists (LTRAs) as add-on treatments in older adults with asthma already taking inhaled corticosteroids (ICSs). Retrospective cohort study. Medicare fee-for-service (FFS) claims (2009-10) for a 10% random sample of beneficiaries continuously enrolled in Parts A, B, and D in 2009. Medicare beneficiaries aged 66 and older continuously enrolled in FFS Medicare with Part D coverage with a diagnosis of asthma before 2009 treated exclusively with ICSs plus LABAs or ICSs plus LTRAs (N = 14,702). The augmented inverse propensity-weighted estimator was used to compare the effect of LABA add-on therapy with that of LTRA add-on therapy on asthma exacerbations requiring inpatient, emergency, or outpatient care and on cardiovascular (CV) events, adjusting for demographic characteristics, comorbidities, and county-level healthcare-access variables. The primary analysis showed that LTRA add-on treatment was associated with greater odds of asthma-related hospitalizations or emergency department visits (odds ratio (OR) = 1.4, P add-on therapy was also less effective in controlling acute symptoms, as indicated by greater use of short-acting beta agonists (rate ratio = 1.58, P add-on treatment was associated with lower odds of experiencing a CV event than LABA treatment (OR = 0.86, P = .006). This study provides new evidence specific to older adults to help healthcare providers weigh the risks and benefits of these add-on treatments. Further subgroup analysis is needed to personalize asthma treatments in this high-risk population. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    This study evaluates the cost of achieving glycemic control with three sodium glucose co-transporter 2 (SGLT2) inhibitors, canagliflozin, dapagliflozin, and empagliflozin, in patients with type 2 diabetes mellitus (T2DM) from the payer perspective in the United Arab Emirates (UAE). A systematic literature review identified randomized controlled trials of antihyperglycemic agents as add-on to metformin in patients with T2DM of 26 ± 4 weeks in duration, published by 10 September 2014. A Bayesian network-meta analysis (NMA) compared HbA1c changes with canagliflozin 100 and 300 mg versus dapagliflozin 10 mg and empagliflozin 10 and 25 mg. The cost associated with a 1% placebo-adjusted HbA1c reduction with each SGLT2 inhibitor as add-on to metformin was calculated based on NMA results and UAE drug costs. In the NMA, canagliflozin 100 and 300 mg were associated with HbA1c reductions (-0.67% and -0.79%) compared with dapagliflozin 10 mg (-0.41%) and empagliflozin 10 and 25 mg (-0.57% and -0.64%). Probabilities of canagliflozin 100 mg performing better were 79%, 60%, and 53% versus dapagliflozin 10 mg and empagliflozin 10 and 25 mg, respectively; probabilities for canagliflozin 300 mg performing better were 88%, 72%, and 65%, respectively. The cost per 1%-point reduction in HbA1c was projected to be lower with canagliflozin 100 and 300 mg ($448 and $422) compared with dapagliflozin 10 mg ($785) and empagliflozin 10 and 25 mg ($527 and $563). Canagliflozin may provide a greater glycemic response at a lower effective cost than dapagliflozin or empagliflozin for patients with T2DM inadequately controlled with metformin from the payer perspective in the UAE.

  8. Add-on Lamotrigine Treatment for Subsyndromal Depression after Manic or Mixed States in Bipolar Disorder Improved the Quality of Life

    Directory of Open Access Journals (Sweden)

    Katsumasa Muneoka

    2012-01-01

    Full Text Available Two cases of patients experienced subsyndromal depression after manic or mixed hypomanic and depressive episodes due to bipolar I (case 1 and II (case 2 disorders prior to the use of lamotrigine. Case 1 showed episodes of mood switching induced by antidepressants and seasonal mood instability. Case 2 showed hippocampal atrophy and a persistent dull headache that preceded the use of lamotrigine. Both were successfully treated with add-on lamotrigine therapy, and the dull headache was effectively treated with olanzapine. Both patients improved in social activity and work performance after these add-on treatments. Thus, add-on treatment with lamotrigine alone or in combination with olanzapine was an effective strategy to improve the quality of life in bipolar depression. Subsyndromal depression that present after the disappearance of the manic or mixed state was suggested to be practical indication for the use of lamotrigine.

  9. Energy and particle core transport in tokamaks and stellarators compared

    2016-07-01

    The paper discusses expectations for core transport in the Wendelstein 7-X stellarator (W7-X) and presents a comparison to tokamaks. In tokamaks, the neoclassical trapped-particle-driven losses are small and turbulence dominates the energy and particle transport. At reactor relevant low collisionality, the heat transport is limited by ion temperature gradient limited turbulence, clamping the temperature gradient. The particle transport is set by an anomalous inward pinch, yielding peaked profiles. A strong edge pedestal adds to the good confinement properties. In traditional stellarators the 3D geometry cause increased trapped orbit losses. At reactor relevant low collisionality and high temperatures, these neoclassical losses would be well above the turbulent transport losses. The W7-X design minimizes neoclassical losses and turbulent transport can become dominant. Moreover, the separation of regions of bad curvature and that of trapped particle orbits in W7-X may have favourable implications on the turbulent electron heat transport. The neoclassical particle thermodiffusion is outward. Without core particle sources the density profile is flat or even hollow. The presence of a turbulence driven inward anomalous particle pinch in W7-X (like in tokamaks) is an open topic of research.

  11. Modeling of radon transport in unsaturated soil

    Chen, C.; Thomas, D.M.; Green, R.

    1995-01-01

    This study applies a recently developed model, LEACHV, to simulate transport of radon through unsaturated soil and compares calculated soil radon activities against field-measured values. For volatile and gas phase transport, LEACHV is modified from LEACHP, a pesticide version of LEACHM, as well-documented one-dimensional model for water and chemical movement through unsaturated soil. LEACHV adds consideration of air temperature changes and air flow driven by barometric pressure change to the other soil variables currently used in LEACHP. It applies diurnal barometric pressure and air temperature changes to reflect more accurately the typical field conditions, Sensitivity analysis and simulated results have clearly demonstrated the relative importance of barometric pressure change, rainfall events, changes in water content, gas advection, and radon source term in radon transport process. Comparisons among simulated results illustrated that the importance of barometric pressure change and its pumping phenomenon produces both fluctuation in soil gas radon activities and an elevation of the long-term average radon activity in shallow soils of an equal magnitude to the disturbed source parameter. Comparisons between measured and simulated soil radon activities showed that LEACHV can provide realistic estimates of radon activity concentration in the soil profile. 41 refs., 10 figs., 2 tabs

    This paper explored the environmental impacts associated with Petro-Canada's project to add petroleum product storage tanks to its refinery in the east-end of Montreal. The project plan is based on a 6 year horizon from 2006-2012. The additional reservoirs would store new products destined for the petrochemical industry and for consumers, thus improving the flexibility and reliability of the refinery. The products would include low sulfur diesel and ethanol gasoline. The project does not involve any increase in refining capacity, and is estimated to cost $15 million. The main issues associated with this project are ambient air quality, the protection of groundwater and soil, as well as the security of areas inhabited by neighbouring areas in risk of a major accident. Emissions of organic compounds, including benzene, are considered minimal considering the use of sealed floating roofs. Geomembranes will be installed under the storage tanks to ensure the protection of groundwater and soil. Any consequences to the population of neighbouring areas resulting from accidents inside the industrial park will be limited since the reservoirs will be located more than 1 km away from a populated area. Quebec's Ministry of Sustainable Development, Environment and Parks recommended that this project be approved as long as the terms and measures of environmental regulations are respected, and that an emergency plan is submitted before the operation of the first reservoir. 1 tab

    The objectives of this study were to evaluate the effectiveness and tolerability of ozone therapy by rectal insufflation as add-on therapy in fibromyalgia management. Patients with fibromyalgia received 24 sessions of ozone therapy during a 12-week period. At each session, the administered dose of ozone was 8 mg (200 mL of gas, at a concentration of 40 μg/mL). Ozone sessions were given 5 days a week during the first 2 weeks, twice a week from weeks 3-6, and weekly from weeks 7-12. Fibromyalgia Impact Questionnaire (FIQ) was the main outcome measure, and was administered at baseline and at weeks 4, 8, and 12. Secondary outcome measures, administered at baseline and at endpoint, were the Pittsburgh Sleep Quality Index, the Beck Depression Inventory, the State and Trait Anxiety Inventory, and the SF-12, the abbreviated form of the Short Form Health Survey. Emergent adverse reactions to treatment were recorded. FIQ total scores decreased significantly during the study period, with the decrease being observed in the first 4 weeks of the study. Significant improvement was also seen both in depression scores and in the Physical Summary Score of the SF-12. Transient meteorism after ozone therapy sessions was the most frequently reported side-effect. At the dose and number of sessions used in this study, ozone therapy by rectal insufflation seems to be beneficial for physical symptoms and depression of fibromyalgia.

    The combination therapy of aliskiren and renin-angiotensin-aldosterone system (RAAS) blocker in chronic kidney disease (CKD) is controversial. Whether such dual blockade can effectively apply to patients with CKD irrespective of stage and amount of proteinuria remains uncertain. We added aliskiren at a dosage of 150 mg/day for six months in 103 Chinese CKD patients who had been treated with angiotensin converting enzyme inhibitors (ACEis) or angiotensin receptor blockers (ARBs) and still had significant proteinuria or uncontrolled hypertension. Blood pressure, serum creatinine, estimated glomerular filtration rate (eGFR), potassium, and spot urine protein-to-creatinine ratio (UPCR) were measured at three and six months after aliskiren add-on therapy and compared with baseline. The combination of aliskiren and ACEi or ARB significantly reduced UPCR by 23% (p=0.001) and mean arterial pressure by 7.9 ± 13.8 mmHg (pproteinuria and inadequately controlled blood pressure. © The Author(s) 2012.

    The multiracial adult population is one of the fastest growing segments of the U.S. population, yet much remains to be learned about multiracial health. Considerable research finds racial/ethnic disparities in self-rated health, however subgroups within the multiracial population have not been consistently described. We use data from the National Longitudinal Survey of Adolescent Health (Add Health) and multivariate logistic regression analyses to compare self-rated health of multiracial and monoracial young adults (n = 7880). Overall, there were no significant differences in poor self-rated health status of multiracial adults as a single group odds ratio 0.84 (95% CI: 0.52-1.36) compared to monoracial White adults. Analyses further revealed important variations in health-status by specific subgroups and show that some multiracial subgroups may not fit existing patterns of health disparities. For instance, Asian-White multiracial adults do not fit documented patterns of health disparities and report better health than monoracial Asian and monoracial White adults. This study illustrates that the inclusion of specific multiracial categories provides evidence to enhance understanding of the pathways that are linked to health outcomes and the implications for health disparities.

    To evaluate the efficacy, safety, and tolerability of lacosamide in adults with LGS in the clinical setting. The present report is a retrospective, open-label treatment study carried out from June 2013 to December 2014 at the National Institute of Colombia. Lacosamide was introduced as add-on therapy. All caregivers were instructed to initiate lacosamide at low doses (25-50 mg) and gradually increasing it every 2 weeks. The efficacy was evaluated based on the reduction in the rate of each countable type of seizure. We also evaluated the retention rate for lacosamide as the number of days with lacosamide during follow-up. The tolerability was evaluated base on account the adverse events. We found that lacosamide only improves the seizure rate in three out of 19 patients with LGS, in two of them by more than 50%. The highest seizure reduction rate was observed in the focal and tonic-clonic seizures. The most commonly reported adverse events were worsening of seizures, aggressiveness and irritability. Nine patients (47.4%) showed worsening of their behavior during the treatment with lacosamide. Lacosamide can exacerbate both, the tonic and astatic seizures, and the encephalopathy associated with this epileptic syndrome. However, it is interesting to consider the likelihood of suppression of generalized tonic-clonic and focal seizures. That is why; lacosamide could be an option after carefully balancing risks and benefits in each individual case. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd.

    Silicon photonics has gained interest for its potential to provide higher efficiency, bandwidth and reduced power consumption compared to electrical interconnects in datacenters and high performance computing environments. However, it is well known that silicon photonic devices suffer from temperature fluctuations due to silicon's high thermo-optic coefficient and therefore, temperature control in many applications is required. Here we present an athermal optical add-drop multiplexer fabricated from ring resonators. We used a sol-gel inorganic-organic hybrid material as an alternative to previously used materials such as polymers and titanium dioxide. In this work we studied the thermal curing parameters of the sol-gel and their effect on thermal wavelength shift of the rings. With this method, we were able to demonstrate a thermal shift down to -6.8 pm/°C for transverse electric (TE) polarization in ring resonators with waveguide widths of 325 nm when the sol-gel was cured at 130°C for 10.5 hours. We also achieved thermal shifts below 1 pm/°C for transverse magnetic (TM) polarization in the C band under different curing conditions. Curing time compared to curing temperature shows to be the most important factor to control sol-gel's thermo-optic value in order to obtain an athermal device in a wide temperature range.

    Open Computing Language (OpenCL) is a high-level language that enables software programmers to explore Field Programmable Gate Arrays (FPGAs) for application acceleration. The Intel FPGA software development kit (SDK) for OpenCL allows a user to specify applications at a high level and explore the performance of low-level hardware acceleration. In this report, we present the FPGA performance and power consumption results of the single-precision floating-point vector add OpenCL kernel using the Intel FPGA SDK for OpenCL on the Nallatech 385A FPGA board. The board features an Arria 10 FPGA. We evaluate the FPGA implementations using the compute unit duplication and kernel vectorization optimization techniques. On the Nallatech 385A FPGA board, the maximum compute kernel bandwidth we achieve is 25.8 GB/s, approximately 76% of the peak memory bandwidth. The power consumption of the FPGA device when running the kernels ranges from 29W to 42W.

    Reamed intramedullary nailing is the current gold standard for the treatment of diaphyseal fractures of the femur and tibia. Current concepts of orthopedic damage control surgery for patients with multiple injuries have placed an emphasis on appropriate surgical timing, limiting blood loss, and the duration of the initial operative procedure(s). Proponents of unreamed nailing have stated that reaming places polytraumatized patients "at risk," in part because it adds to the length of the surgical procedure and may exacerbate the severity of a patient's pulmonary injury. The purpose of this study was to determine how many minutes reaming actually takes and what percentage of operative time reaming comprises during intramedullary nailing of femoral and tibial shaft fractures. Intraoperative timing data were collected prospectively on a total of 52 patients with 54 fractures (21 femoral and 33 tibial) who underwent reamed intramedullary nailing of acute closed or open femoral or tibial shaft fractures over a 10-month period. Total operating room, surgical, and reaming times were collected. The average reaming time for femur and tibia fractures was 6.9 minutes and 7 minutes, respectively. On average, reaming accounted for 4.9% of the surgical time and 3.2% of the total operating room time for femur fractures and 4.9% of the surgical time and 3.4% of the total operating room for tibia fractures. Our results show that reaming comprises a small percentage of the operative time and the total time a patient spends in the operating room.

    While problem-based learning (PBL) has been widely implemented in medical education, it has been acknowledged to be resource-intensive, particularly in terms of academics' time. In some institutions, such as Bond University (Australia), casual facilitators have been employed (paid hourly) to oversee the PBL tutorials. Apart from considerable experience as PBL facilitators, they also have expertise as allied health professionals or biomedical scientists. Several facilitators have educational qualifications. Recognising that their roles have expanded beyond the PBL tutorial room, we canvassed PBL facilitators in terms of their contributions to Bond University's medical programme. We can report that our facilitators have contributed to the renewal of Bond's medical programme, from design (e.g. curriculum structure, case-writing) to PBL case reviews. They are also involved in formative and summative assessment. Facilitators identified that, because of their prolonged involvement with the students in small groups, they consider themselves more than facilitators of student learning. They are role models and personal guides. Recognising the value these casually employed facilitators have added to our medical programme, we will continue to develop their skills in, for example, reviewing cases and assessment. We recommend that if institutions do employ casual facilitators, their expertise and experience can add value to the curriculum and to students' experience.

    2012-11-01

    An algorithm for the real time synthesis of internal combustion engine noise is presented. Through the analysis of a recorded engine noise signal of continuously varying engine speed, a dataset of sound samples is extracted allowing the real time synthesis of the noise induced by arbitrary evolutions of engine speed. The sound samples are extracted from a recording spanning the entire engine speed range. Each sample is delimitated such as to contain the sound emitted during one cycle of the engine plus the necessary overlap to ensure smooth transitions during the synthesis. The proposed approach, an extension of the PSOLA method introduced for speech processing, takes advantage of the specific periodicity of engine noise signals to locate the extraction instants of the sound samples. During the synthesis stage, the sound samples corresponding to the target engine speed evolution are concatenated with an overlap and add algorithm. It is shown that this method produces high quality audio restitution with a low computational load. It is therefore well suited for real time applications.

    To explore the rate of add-on therapy with solifenacin in men with voiding and storage lower urinary tract symptoms (LUTS) after tamsulosin monotherapy and to explore predictive factors for starting solifenacin add-on therapy. Men aged ≥ 45 years with IPSS ≥ 12 and symptoms of OAB (OAB-V8 ≥ 8, micturition ≥ 8/24 h, urgency ≥ 2/24 h) were enrolled to receive tamsulosin 0.2 mg once daily. After 4 weeks, men with residual symptoms of OAB and reported 'dissatisfied' or 'a little satisfied' were received solifenacin 5 mg in combination with tamsulosin monotherapy. Subjects completed an IPSS, a Quality of life (QoL) index, OAB V8, and an International Consultation of Incontinence Questionnaire (ICIQ)-Male LUTS, and patient perception of bladder condition (PPBC) at baseline and week 4. Of a total of 305 patients, 254 patients completed 4 weeks of tamsulosin treatment. For 176 patients, solifenacin was added (69.3%). Significant predictive factors of solifenacin add-on therapy included long LUTS duration, high IPSS, number of micturitions per 24 h, more urgency episodes, high urgency severity score in a voiding diary and high OAB V8 score. Based on multivariable analysis, potential predictive factors of solifenacin add-on therapy included long LUTS duration (OR = 1.008, 95% CI: 1.001-1.014), high serum PSA (OR = 1.543, 95% CI: 1.136-2.095) and small prostate size (OR = 0.970, 95% CI: 0.947-0.994) (p tamsulosin monotherapy. Two thirds of men with voiding and storage LUTS needed to add anticholinergics after 4 weeks of tamsulosin monotherapy. Patients with longer lasting symptoms and storage symptoms with small prostate volume may require the anticholinergic add-on. © 2014 John Wiley & Sons Ltd.

    Full Text Available Transport and mobility are essential preconditions for sustainable - development. Transport affects social, economic and environmental sustainability. Environmental sustainability is affected negatively by transport through the consumption of non renewable energy, the emission of harmful pollutants and - greenhouse gases. Sustainable transport is safe, high quality and accessible to all, ecologically sound, economically viable and positive contributor to local, national and international development. Integrated urban and rural transport planning, as well as supportive fiscal and regulatory policies, combined with the development of new technologies and greater international cooperation, are key factors for achieving a transport sector that meets the requirements of sustainable development.

    To investigate the long-term efficacy and safety of empagliflozin as add-on therapy to pioglitazone with or without metformin in patients with type 2 diabetes mellitus. Of 498 patients randomized to empagliflozin 10 mg, empagliflozin 25 mg, or placebo once daily for 24 weeks in the EMPA-REG PIO™ study, 305 (61.2%) were treated in a double-blind extension trial for ≥52 weeks (total duration ≥76 weeks). Exploratory end points at week 76 included changes from baseline in glycosylated hemoglobin (HbA1c), weight, and blood pressure assessed using ANCOVA in patients who received ≥1 dose of study drug and had a baseline HbA1c measurement in the initial study. Compared with placebo, adjusted mean (95% CI) changes from baseline in HbA1c level at week 76 were -0.59% (-0.79% to -0.40%; P empagliflozin 10 mg (-6.5 [-8.6 to -4.4] mmol/mol) and -0.69% (-0.88% to -0.50%; P empagliflozin 25 mg (-7.5 [-9.6 to -5.4] mmol/mol). Compared with placebo, adjusted mean (95% CI) changes from baseline in weight at week 76 were -2.0 kg (-2.7 to -1.2 kg; P empagliflozin 10 mg and 25 mg, respectively. Compared with placebo, only empagliflozin 25 mg led to significant reductions in systolic blood pressure (adjusted mean [95% CI] change: -3.7 mmHg [-6.1 to -1.3 mmHg]; P = 0.003) and diastolic blood pressure (adjusted mean [95% CI] change: -2.2 mmHg [-3.7 to -0.7 mmHg]; P = 0.004). Sensitivity analyses were consistent with these results for HbA1c level, fasting plasma glucose concentration, and weight, but revealed no significant difference between empagliflozin and placebo in change from baseline in systolic or diastolic blood pressure at week 76. Confirmed hypoglycemic adverse events (glucose ≤3.9 mmol/L and/or requiring assistance) were reported in 4.2%, 1.8%, and 3.0% of patients treated with placebo, empagliflozin 10 mg, and empagliflozin 25 mg, respectively; 1 patient each taking placebo and empagliflozin 25 mg required assistance.

    Hospice in-person visits in the last week of life are critical to ensure quality of care. In 2016, The Centers for Medicare & Medicaid Services (CMS) introduced a Service Intensity Add-on (SIA) payment for in-person routine home care (RHC) visits by a registered nurse or social worker in the last 7 days of life. The aim of the study was to examine visit patterns in the last week of life and provide SIA payment impact estimates. Hospice data from 42 volunteer hospice programs for the 6-year period of 2005-2010 were examined. The data included information on the type and duration of visits/other care, the staff discipline, and patient demographics, diagnoses, date of death, and care setting (home, assisted living, nursing home). In their last week of life, 251,407 decedents received 2,818,695 visits during 1,352,638 RHC days. Forty-four percent of the decedents had at least one SIA-eligible visit (in-person direct care visit by a registered nurse (RN) or social worker (SW)); 6.6% had only phone contact, and 30.4% had no hospice contact. Rates of RHC days with SIA-eligible days varied considerably across hospices (31% to 60.9%). For the 86.3% decedents with any SIA-eligible visits, average SIA payment would have been $202.5 (Median = $177.2, inter quartile range [IQR] = $108.3-$275.6), which represents a 21.6% increase over the average regular RHC payments received during the last week of life. The relative size of the new SIA payment introduced by CMS has the potential to increase RN/SW visits and reduce disparities in visit patterns in the last week of life.

  13. A cost-effective add-on-value card-assisted firewall over Taiwan's NHI VPN framework.

    2007-06-01

    Besides the overall budget for building the infrastructure of a healthcare-service-based virtual private network (VPN) in Taiwan, two issues were considered critical for its acceptance by the country's 17,000 plus medical institutions. One was who was to pay for the network (ADSL or modem) connection fee; the other was who was to pay for the firewall/anti-virus software. This paper addresses the second issue by proposing an efficient freeware firewall, named card-assisted firewall (CAF), for NHI VPN edge-hosts, which is also an add-on-value application of the National Healthcare IC card that every insurant and medical professional has. The innovative concept is that any NHI VPN site (edge-host) can establish diversified secure-authenticated connections with other sites only by an authentication mechanism, which requires a NHI Java card state machine and the Access Control List of the host. It is different from two-factor authentication cards in four ways: (1) a PIN code is not a must; (2) it requires authentication with the remote IC card Data Centre; (3) the NHI cards are already available, no modification is needed, and there is no further cost for the deployment of the cards; (4) although the cards are in the reader, the communication cannot start unless the cards are in the corresponding states; i.e. the states allow communication. An implementation, on a Microsoft Windows XP platform, demonstrated the system's feasibility over an emulation of the NHI VPN framework. It maintained a high line speed, the driver took up 39 KB of disk space, installation was simple, not requiring any extra hardware or software, and the average packet processing time of the CAF driver measured was 0.3084 ms. The average overhead in comparing the Access Control List predefined routing in card, in an FTP testing experiment, was 5.7 micros (receiving) and 8 micros (sending).

    Nicotine is considered an etiologic factor for chronic inflammatory phenomena within the periodontal ligament that may result in loss of periodontal attachment. Considering that smokers account for 26% of adult and 12% of adolescent patients in orthodontic practice, we performed in vivo and in vitro studies as to whether orthodontic forces may add to the nicotine-induced loss of periodontal bone. Fourteen male rats (Fischer 344 inbred) were used. Seven of these served as controls, while the other seven received daily subcutaneous injections of 1.89 mg L-nicotine per kg body weight. Both groups were exposed to orthodontic mesialization of the first two upper left molars using a NiTi closed-coil spring, the contralateral side serving as control. Periodontal bone loss was assessed by cone-beam computed tomography (CBCT). Human periodontal fibroblasts were stressed by compression (2 g/cm(2)) and/or nicotine (3/5/7.5 µmol), and the expression of cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2), interleukin-6 (IL-6), osteoprotegerin (OPG), and receptor activator of nuclear factor κB ligand (RANKL) was determined at the transcriptional level by quantitative real-time polymerase chain reaction (qRT-PCR) and at the translational level by enzyme-linked immunosorbent assay (ELISA). In addition, differentiation of co-cultured murine RAW264.7 cells to osteoclast-like cells was quantified by tartrate-resistant acid phosphatase (TRAP) staining. Orthodontic force application in vivo led to a significant increase in nicotine-induced periodontal bone loss, and cell compression in vitro to increased COX-2, PGE2, IL-6, and RANKL expression, reduced OPG expression, and enhanced differentiation of RAW264.7 cells to osteoclast-like cells compared to nicotine alone. Additional loss of periodontal bone must be expected during orthodontic treatment of smokers. Clinicians should inform their patients of this increased risk and refrain from performing tooth movements before cessation of

The right hindlimb of three and one-half-month-old Sprague-Dawley female rats were immobilized by right hindlimb immobilization (RHLI) in which the right hindlimb was underloaded and the contralateral left limb was overloaded during ambulation. After 4 or 12 weeks of RHLI, the rats were treated with 3 or 6 mg PGE2/kg/day and RHLI for 8 or 16 weeks. Bone histomorphometry was performed on microradiographs of PTM. Immobilization (IM) induced a transient cancellous bone loss and decreased trabecular thickness, number and node density, and increased free end density that established a new steady state after 4 weeks of IM. Three or 6 mg PGE2/kg/d for 8 weeks beginning at 4 or 12 weeks of IM completely restored cancellous bone mass (+127 to +188 percent) and structure to the age-related control levels in spite of continuous IM. Another 8 weeks of treatment maintained bone mass and architecture at these levels. No differences in cancellous bone mass and architecture were found between the overloaded PTM or RHLI rats and the age-related controls. However, 3 and 6 mg/kg/d of PGE2 treatment started at 4 or 12 weeks for 8 weeks significantly increased cancellous bone mass in the overloaded PTM (+45 to +74% of untreated controls), and another 8 weeks of treatment maintained bone mass at these levels. Our findings indicate that daily 3 or 6 mg PGE2/kg/d treatment restores and maintains PTM cancellous bone mass in continuously immobilized (right) tibiae, and adds and maintains extra bone to slightly overloaded PTM cancellous bone in female rats.

    Water-level modeling is used for multiple-well aquifer tests to reliably differentiate pumping responses from natural water-level changes in wells, or “environmental fluctuations.” Synthetic water levels are created during water-level modeling and represent the summation of multiple component fluctuations, including those caused by environmental forcing and pumping. Pumping signals are modeled by transforming step-wise pumping records into water-level changes by using superimposed Theis functions. Water-levels can be modeled robustly with this Theis-transform approach because environmental fluctuations and pumping signals are simulated simultaneously. Water-level modeling with Theis transforms has been implemented in the program SeriesSEE, which is a Microsoft® Excel add-in. Moving average, Theis, pneumatic-lag, and gamma functions transform time series of measured values into water-level model components in SeriesSEE. Earth tides and step transforms are additional computed water-level model components. Water-level models are calibrated by minimizing a sum-of-squares objective function where singular value decomposition and Tikhonov regularization stabilize results. Drawdown estimates from a water-level model are the summation of all Theis transforms minus residual differences between synthetic and measured water levels. The accuracy of drawdown estimates is limited primarily by noise in the data sets, not the Theis-transform approach. Drawdowns much smaller than environmental fluctuations have been detected across major fault structures, at distances of more than 1 mile from the pumping well, and with limited pre-pumping and recovery data at sites across the United States. In addition to water-level modeling, utilities exist in SeriesSEE for viewing, cleaning, manipulating, and analyzing time-series data.

    To quantify use of high dose inhaled corticosteroids (ICS) and add-on therapy in adults, and children aged 12 and over, in the community. Cross-sectional observational survey of UK general practice prescribing records from July 2002 to June 2003 utilising the Doctors Independent Network clinical database. 30,895 patients aged 12 and over were treated for asthma with inhaled corticosteroids, with a quantifiable daily dose recommendation in 22,027 cases. Twenty-seven percent (95% Confidence Intervals 26-28%) were prescribed 'high-dose' ICS (>800 mcg/day beclomethasone or equivalent). Of these, 32% (31-33%) were not currently prescribed add-on therapy (long acting B2 agonists, leukotriene antagonists, theophylines), and most of these (84%, 82-86%) had never received a prior trial of add-on therapy. High dose ICS therapy was commonly prescribed to people with asthma, frequently without co-prescribed add-on therapy. Many adults with more severe asthma may be receiving treatment that does not accord with current evidence of best practice.

    2015-10-01

    To compare the functional outcomes of primary implantation of a monofocal intraocular lens (IOL) in the capsular bag and an add-on multifocal IOL in the sulcus with the functional results of a conventional multifocal posterior chamber IOL and to evaluate the multifocal add-on IOL as an effective alternative to a conventional multifocal IOL. Ernst von Bergmann Eye Clinic, Potsdam, Germany. Prospective nonrandomized case series. Cataract surgery patients were assigned to have bilateral implantation of a monofocal IOL (Aspira-aAY) in the capsular bag followed by a multifocal add-on IOL (Diff-sPB) in the sulcus (Group A) or with a conventional multifocal IOL (Diffractiva-s) in the capsular bag (Group B). The main study outcomes were assessed at the last follow-up visit (6 months postoperatively) and included refraction, intraocular pressure, visual acuity, reading speed, contrast sensitivity, defocus curve, and patient satisfaction. The study comprised 26 patients (52 eyes) Cataract surgery was uneventful in all cases. No severe complications were observed 6 months postoperatively. Visual performance with a multifocal diffractive add-on IOL was equivalent to that achieved with a conventional multifocal diffractive posterior chamber IOL. Similarly, there were no significant differences in patient satisfaction and reading speed for any type of letter size between groups (P > .05). Implanting a multifocal add-on IOL in the sulcus in addition to a monofocal IOL in the capsular bag produced outcomes similar to those of single implantation of a standard multifocal IOL in the capsular bag.

  5. Acute phase reactants add little to composite disease activity indices for rheumatoid arthritis: validation of a clinical activity score

    2005-01-01

    Introduction Frequent assessments of rheumatoid arthritis (RA) disease activity allow timely adaptation of therapy, which is essential in preventing disease progression. However, values of acute phase reactants (APRs) are needed to calculate current composite activity indices, such as the Disease Activity Score (DAS)28, the DAS28-CRP (i.e. the DAS28 using C-reactive protein instead of erythrocyte sedimentation rate) and the Simplified Disease Activity Index (SDAI). We hypothesized that APRs make limited contribution to the SDAI, and that an SDAI-modification eliminating APRs – termed the Clinical Disease Activity Index (CDAI; i.e. the sum of tender and swollen joint counts [28 joints] and patient and physician global assessments [in cm]) – would have comparable validity in clinical cohorts. Method Data sources comprised an observational cohort of 767 RA patients (average disease duration 8.1 ± 10.6 years), and an independent inception cohort of 106 patients (disease duration 11.5 ± 12.5 weeks) who were followed prospectively. Results Our clinically based hypothesis was statistically supported: APRs accounted only for 15% of the DAS28, and for 5% of the SDAI and the DAS28-CRP. In both cohorts the CDAI correlated strongly with DAS28 (R = 0.89–0.90) and comparably to the correlation of SDAI with DAS28 (R = 0.90–0.91). In additional analyses, the CDAI when compared to the SDAI and the DAS28 agreed with a weighted kappa of 0.70 and 0.79, respectively, and comparably to the agreement between DAS28 and DAS28-CRP. All three scores correlated similarly with Health Assessment Questionnaire (HAQ) scores (R = 0.45–0.47). The average changes in all scores were greater in patients with better American College of Rheumatology response (P < 0.0001, analysis of variance; discriminant validity). All scores exhibited similar correlations with radiological progression (construct validity) over 3 years (R = 0.54–0.58; P < 0.0001). Conclusion APRs add little information on

    2017-01-01

    To define and examine the relationship between self-reported childhood abuse and migraine among young adults. Headache and migraine have been linked to childhood abuse in numerous studies, but there is incomplete characterization of headache types, and limited assessment of abuse types and frequency. Only one population-based study has examined the relationship between emotional abuse and migraine. None have investigated the temporal relationship between onset of abuse and of migraine. We analyzed data from 14,356 adults aged 24-32 years in Wave 4, which is a cross-sectional subset of the longitudinal Add Health study. Participants were queried regarding abuse (emotional, physical and sexual) during childhood, diagnosis of migraine, depression and anxiety by healthcare providers, and symptoms of current depression. We used logistic regression to estimate the association between childhood abuse and migraine, controlling for socio-demographic factors, current depression, and lifetime diagnosis of anxiety and depression. About 14% (n = 2040) of respondents reported migraine. Participants with migraine (vs no migraine) reported significantly higher rates of childhood abuse overall (60.6% vs 48.9%), including emotional (57.8% vs 45.4%), sexual (8.4% vs 4.6%) and physical (22.4% vs 17.9%) abuse. Emotional abuse had a stronger association with migraine (odds ratio [OR] 1.62; 95% confidence interval [CI] 1.43-1.85) when compared with physical (OR 1.06; 95% CI 0.89-1.68) and sexual abuse (OR 1.06; 95% CI 0.93-1.68), adjusting for socio-demographic factors. The emotional abuse-migraine association remained even when controlling for lifetime diagnosis of depression and anxiety (OR 1.37; 95% CI 1.19-1.57) and for current depression (OR 1.47; 95% CI 1.30-1.67). The odds of migraine increased with increasing number of abuse types reported. There was a U-shaped distribution of odds of migraine associated with frequency of occurrences of emotional abuse, peaking at one time

    We discuss the signature of the anomalous breaking of the superconformal symmetry in N=1 super Yang Mills theory, mediated by the Ferrara-Zumino hypercurrent (J) with two vector (V) supercurrents (JVV) and its manifestation in the anomaly action, in the form of anomaly poles. This allows to investigate in a unified way both conformal and chiral anomalies. The analysis is performed in parallel to the Standard Model, for comparison. We investigate, in particular, massive deformations of the N=1 theory and the spectral densities of the anomaly form factors which are extracted from the components of this correlator. In this extended framework it is shown that all the anomaly form factors are characterized by spectral densities which flow with the mass deformation. In particular, the continuum contributions from the two-particle cuts of the intermediate states turn into poles in the zero mass limit, with a single sum rule satisfied by each component. Non anomalous form factors, instead, in the same anomalous correlators, are characterized by non-integrable spectral densities. These tend to uniform distributions as one moves towards the conformal point, with a clear dual behaviour. As in a previous analysis of the dilaton pole of the Standard Model, also in this case the poles can be interpreted as signaling the exchange of a composite dilaton/axion/dilatino (ADD) multiplet in the effective Lagrangian. The pole-like behaviour of the anomaly form factors is shown to be a global feature of the correlators, present at all energy scales, due to the sum rules. A similar behaviour is shown to be present in the Konishi current, which identifies additional composite states. We conclude that global anomalous currents characterized by a single flow in the perturbative picture always predict the existence of composite interpolating fields. In case of gauging of these currents, as in superconformal theories coupled to gravity, we show that the cancellation of the corresponding

  12. Theory of contributon transport

    International Nuclear Information System (INIS)

    Painter, J.W.; Gerstl, S.A.W.; Pomraning, G.C.

    1980-10-01

    A general discussion of the physics of contributon transport is presented. To facilitate this discussion, a Boltzmann-like transport equation for contributons is obtained, and special contributon cross sections are defined. However, the main goal of this study is to identify contributon transport equations and investigate possible deterministic solution techniques. Four approaches to the deterministic solution of the contributon transport problem are investigated. These approaches are an attempt to exploit certain attractive properties of the contributon flux, psi = phi phi + , where phi and phi + are the solutions to the forward and adjoint Boltzmann transport equations

    International Nuclear Information System (INIS)

    Jones, E.

    1990-01-01

    Over the past 25 years extensive federal legislation involving the handling and transport of hazardous materials/waste has been passed that has resulted in numerous overlapping regulations administered and enforced by different federal agencies. The handling and transport of hazardous materials/waste involves a significant number of workers who are subject to a varying degree of risk should an accident occur during handling or transport. Effective transportation training can help workers address these risks and mitigate them, and at the same time enable ORNL to comply with the federal regulations concerning the transport of hazardous materials/waste. This presentation will outline how the Environmental and Health Protection Division's Technical Resources and Training Section at the Oak Ridge National Laboratory, working with transportation and waste disposal personnel, have developed and implemented a comprehensive transportation safety training program to meet the needs of our workers while satisfying appropriate federal regulations. 8 refs., 3 tabs

    To evaluate the safety and efficacy of empagliflozin for 52 weeks as add-on to one other oral antidiabetes therapy in Japanese patients with type 2 diabetes mellitus (T2DM). Patients on biguanide (n = 133), thiazolidinedione (n = 273), α-glucosidase inhibitor (n = 139), dipeptidyl-peptidase-4 inhibitor (n = 139) or glinide (n = 140) were randomized 1 : 1 to receive empagliflozin 10 or 25 mg double-blind as add-on therapy for 52 weeks. Patients on sulphonylurea (SU; n = 336) were randomized 2 : 2 : 1 to receive empagliflozin 10 or 25 mg double-blind or open-label metformin as add-on therapy for 52 weeks. The primary objective was to evaluate safety. Change from baseline in glycated haemoglobin (HbA1c) at week 52 was a secondary endpoint. Adverse events (AEs) were reported in 67.6-84.6% of patients receiving empagliflozin. Confirmed hypoglycaemic AEs (plasma glucose ≤70 mg/dl and/or requiring assistance) were reported in 4.4 and 6.6%, respectively, of patients receiving empagliflozin 10 and 25 mg as add-on to SU and in 0.0 to 2.9%, respectively, of patients receiving empagliflozin 10 and 25 mg as add-on to other therapies. Baseline mean ± standard deviation HbA1c ranged from 7.51 ± 0.73 to 8.06 ± 0.76% across background therapy groups. At week 52, adjusted mean ± standard error changes from baseline in HbA1c ranged from -0.77 ± 0.06 to -1.00 ± 0.06% in patients receiving empagliflozin. In Japanese patients with T2DM, empagliflozin 10 and 25 mg as add-on to one other oral antidiabetes therapy for 52 weeks were well tolerated and were associated with clinically meaningful reductions in HbA1c. © 2015 John Wiley & Sons Ltd.

  18. Choosing Dipeptidyl Peptidase-4 Inhibitors, Sodium-glucose Cotransporter-2 Inhibitors, or Both, as Add-ons to Metformin: Patient Baseline Characteristics Are Crucial.

    2017-12-01

    Type 2 diabetes remains a poorly managed disease, with only about half of individuals with type 2 diabetes meeting guideline-recommended glycosylated hemoglobin (HbA 1C ) targets. A major proportion of those who have not met HbA 1C goals have an HbA 1C add-ons to metformin to help these individuals meet their HbA 1C goals. This commentary reviews and provides guidance on how baseline factors can assist in the decision between the 2 classes or using both as add-ons to metformin. The important clinical studies comparing the glycemic efficacy of DPP-4i versus SGLT2i or their combination as add-ons to metformin with a focus on the influence of baseline HbA 1C on glycemic efficacy will be discussed and interpreted. The impact of estimated glomerular filtration rate and age on the glycemic efficacy of DPP-4i and SGLT2i will also be put into perspective. At HbA 1C add-on to metformin; SGLT2i are associated with larger HbA 1C improvements than DPP-4i at higher HbA 1C levels. In cases of HbA 1C ≥8.0%, dual DPP-4i-SGLT2i add-on therapy to metformin should be considered to help more patients achieve glycemic targets. The glycemic efficacy of SGLT2i, but not DPP-4i, declines with progressive renal insufficiency. In older adults, DPP-4i maintain their tolerability and efficacy, while SGLT2i may become less efficacious due to reduced renal function, and may be associated with higher rates of volume-related adverse effects. Although both DPP-4i and SGLT2i are effective add-on antihyperglycemic therapies to metformin monotherapy, baseline characteristics, such as HbA 1C , renal function, and age, should be considered when choosing between the 2 classes to allow for optimal and timely diabetes management.

  1. Impact of centrifugal drifts on ion turbulent transport

    Belli, E. A.; Candy, J.

    2018-03-01

    The influence of sonic toroidal rotation on gyrokinetic stability and transport is studied, with important implications for heavy impurity dynamics. When centrifugal drifts and electrostatic trapping corrections are included, significant modifications to the calculated transport of heavy impurities are observed. These high-rotation corrections add to the standard Coriolis drift and toroidal rotation shear drive which are normally included in gyrokinetics. Yet, because of their complexity, centrifugal and electrostatic trapping terms (quadratic in the main ion Mach number) are not generally included in gyrokinetic codes. In this work, we explore the implications of using reduced descriptions of the rotational physics. For heavy impurities such as tungsten, cross terms due to the centrifugal force can dominate the rotation dynamics, and neglecting them is shown to lead to large errors in the impurity particle flux.

    Transportation demands a large and increasing share of total energy consumption in Europe. At the same time many European countries are facing difficult decisions in achieving their long term environmental goals. Therefore energy policy, environmental policy and transport policy should be seen and discussed in a common perspective. In particular the relative contribution from the transport sector and the energy sector involves a number of important and difficult issues. The aim of the conference was to bring together economists, scientists, manufactures, energy planners, transport planners, and decision makers in order to discuss the importance of the transport sector in relation to energy demand and long term environmental goals. General conference sessions covered. Trends in Transport Energy Demand and Environmental constraints, Technological Development and New Transport Systems, Lifestyle Changes and the Transport Sector, Megacities: Solutions to the Transport and Air Pollution Problems, Effectiveness of Public Policies, Transport and Energy sector, and Methods, Models and Data. The conference took place at Hotel Marienlyst, Elsinore, Denmark and attracted wide interest. The participants represented 14 different countries covering international organisations, ministries, universities, research centres, consulting firms, industry etc. (EG)

  3. Disorder Induced Transport

    Steimel, Joshua; Kachman, Tal; Aragones, Juan; Alexander-Katz, Alfredo

    Transport of active or driven particles plays a crucial role in a myriad of processes ranging from biological systems to quantum phenomena. Here we study the transport of active spinning particles in a confined substrate that contains fixed obstacles. Except for a handful of systems, a disordered environment in the form of impurities or obstacles in a material will inhibit transport, and under some circumstances lead to localization. Such phenomena has been directly seen in transport of light in disordered photonic crystals. This is an important question because many vital biological processes depend on the active transport of molecules inside cells and organisms, from molecular motors to cellular transport. In particular, it is vital to know whether disorder leads to the inhibition of transport and localization, or enhances transport. We demonstrate with experiments and simulations that, contrary to intuition, active spinning matter exhibits a disorder-induced delocalization transition dependent on the local order of the obstacles on the substrate. For the regimes studied, we always find anomalous super-diffusive transport that slowly approaches the diffusive regime in the limit of high activity. These results shed light on the effect of hydrodynamic boundary conditions and optimal transport processes in active matter in disordered environments.

    We examine the links between fossil-fuel-based transportation, greenhouse-gas emissions, and health. Transport-related carbon emissions are rising and there is increasing consensus that the growth in motorised land vehicles and aviation is incompatible with averting serious climate change. The energy intensity of land transport correlates with its adverse health effects. Adverse health effects occur through climate change, road-traffic injuries, physical inactivity, urban air pollution, energy-related conflict, and environmental degradation. For the world's poor people, walking is the main mode of transport, but such populations often experience the most from the harms of energy-intensive transport. New energy sources and improvements in vehicle design and in information technology are necessary but not sufficient to reduce transport-related carbon emissions without accompanying behavioural change. By contrast, active transport has the potential to improve health and equity, and reduce emissions. Cities require safe and pleasant environments for active transport with destinations in easy reach and, for longer journeys, public transport that is powered by renewable energy, thus providing high levels of accessibility without car use. Much investment in major road projects does not meet the transport needs of poor people, especially women whose trips are primarily local and off road. Sustainable development is better promoted through improving walking and cycling infrastructures, increasing access to cycles, and investment in transport services for essential needs. Our model of London shows how increased active transport could help achieve substantial reductions in emissions by 2030 while improving population health. There exists the potential for a global contraction and convergence in use of fossil-fuel energy for transport to benefit health and achieve sustainability.

  5. Energy policy in transport and transport policy

    Explanations for, and indirect evidence of, imperfections in the market for private passenger vehicle fuel economy suggest there is a reasonable case for combining fuel economy standards and fuel or carbon taxes to contribute to an energy policy that aims to reduce greenhouse gas emissions and improve energy security. Estimates of key elasticities, including the rebound effect, indicate that the positive and negative side-effects of fuel economy measures on transport activities and external costs are limited. However, an energy policy for transport does not replace a transport policy that aims to manage the main transport externalities including congestion and local pollution. Conventional marginal cost estimates and standard cost-benefit reasoning suggest that policies that address congestion and local pollution likely bring benefits at least as large as those from fuel economy measures. But the large uncertainty on the possible effects of greenhouse gas emissions constitutes a strong challenge for standard cost-benefit reasoning. Emerging results from methods to cope with this uncertainty suggest that policies to stimulate the widespread adoption of low-carbon technologies in transport are justified.

    Endometriosis can recur after either surgical or medical therapy. Long-term medical therapy is implemented to treat symptoms or prevent recurrence. Dienogest and gonadotropin-releasing hormone (GnRH) analogues with hormone add-back therapy seem to be equally effective for long-term treatment of pain symptoms associated with endometriosis. There is insufficient evidence to support the superiority of one therapy over the other. However, add-back hormone therapy (HT) is recommended for patients using GnRH agonists. The treatment selection depends on therapeutic effectiveness, tolerability, drug cost, the physician's experience, and expected patient compliance.

    For the first time, an optimized optical add drop filter (OADF) for dense wavelength-division-multiplexing systems is demonstrated using the Texas Instruments microelectro-mechanical-system Digital Micromirror Device (DMD™). This OADF features a polarization-insensitive fault-tolerant broadband operation, low loss, and the ability to selectively add/drop with high-wavelength-resolution multiple channels in the C telecommunications band. The proof-of-concept OADF designed for the C-band demonstrates low insertion loss, 0.15-dB polarization dependent loss, 3-dB wavelength resolution of 0.4 nm, and an average crosstalk of better than 30 dB. With the use of a reference mirror, the OADF becomes a multiwavelength 2 x 2 routing switch.

    We demonstrate highly compact third-order silicon microring add-drop filters. The microring resonator has a small radius of 2.5 mum and a very large free spectral range of 32 nm at 1.55 mum. Experimental results show a low add-drop crosstalk of around -20 dB. Box-like channel dropping response is demonstrated, and it has a passband of ~ 1 nm (125 GHz), fast rolling-off (slope ~ 0.2 dB/GHz), high out-of-band signal rejection of around 40 dB and a low drop loss. Simulation agrees well with experiments in power transmission, and the group delay is also simulated and the variation is less than 1 ps within the passband. The propagation loss in microring resonators is optimized.

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment (TSPA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data. The transport model considers advective transport and diffusive transport

    The Japan Society of Hepatology guidelines indicate that hepatitis C virus (HCV) protease inhibitor combination therapy with simeprevir (SMV), pegylated-interferon (Peg-IFN), and ribavirin (RBV) is a therapeutic option for patients who fail to respond to a direct direct-acting antiviral-containing regimen. However, treatment outcomes have room for improvement. Fluvastatin (FLV) add-on treatment in Peg-IFN and RBV combination therapy for HCV-infected patients significantly improved the sustained virologic response (SVR), but the add-on effect of FLV on SMV combination therapy is not well understood. This was a prospective, randomized, multicenter study in which a total of 61 HCV genotype 1b-infected patients were recruited and 60 eligible patients were randomly allocated to two groups that received 12 weeks of SMV/Peg-IFN/RBV followed by 12 weeks of Peg-IFN/RBV with or without 24 weeks of FLV. The SVR rate and adverse events were compared between the two groups. Thirty-one patients were allocated to the FLV add-on group and 29 patients were allocated to the control group. Baseline clinical factors, including median age, baseline platelet count, alanine aminotransferase level, HCV RNA titer, Fibrosis-4 index, and rate of IL28B minor genotype, were all similar between the two groups. The rapid virologic response, end-of-treatment response rates, SVR rates at 24 weeks after treatment, and safety profiles were also similar between the two groups. This prospective, randomized, multicenter study indicated that FLV had no add-on effect when given with SMV/Peg-IFN/RBV combination therapy for genotype 1b HCV-infected patients. © 2017 The Japan Society of Hepatology.

  16. Heat in the Barents Sea: transport, storage, and surface fluxes

    Directory of Open Access Journals (Sweden)

    L. H. Smedsrud

    2010-02-01

    Full Text Available A column model is set up for the Barents Sea to explore sensitivity of surface fluxes and heat storage from varying ocean heat transport. Mean monthly ocean transport and atmospheric forcing are synthesised and force the simulations. Results show that by using updated ocean transports of heat and freshwater the vertical mean hydrographic seasonal cycle can be reproduced fairly well.

    Our results indicate that the ~70 TW of heat transported to the Barents Sea by ocean currents is lost in the southern Barents Sea as latent, sensible, and long wave radiation, each contributing 23–39 TW to the total heat loss. Solar radiation adds 26 TW in the south, as there is no significant ice production.

    The northern Barents Sea receives little ocean heat transport. This leads to a mixed layer at the freezing point during winter and significant ice production. There is little net surface heat loss annually in the north. The balance is achieved by a heat loss through long wave radiation all year, removing most of the summer solar heating.

    During the last decade the Barents Sea has experienced an atmospheric warming and an increased ocean heat transport. The Barents Sea responds to such large changes by adjusting temperature and heat loss. Decreasing the ocean heat transport below 50 TW starts a transition towards Arctic conditions. The heat loss in the Barents Sea depend on the effective area for cooling, and an increased heat transport leads to a spreading of warm water further north.

    Transport is the sector with the highest final energy consumption and, without any significant policy changes, is forecast to remain so. In 2008, the IEA published 25 energy efficiency recommendations, among which four are for the transport sector. The recommendations focus on road transport and include policies on improving tyre energy efficiency, fuel economy standards for both light-duty vehicles and heavy-duty vehicles, and eco-driving. Implementation of the recommendations has been weaker in the transport sector than others. This paper updates the progress that has been made in implementing the transport energy efficiency recommendations in IEA countries since March 2009. Many countries have in the last year moved from 'planning to implement' to 'implementation underway', but none have fully implemented all transport energy efficiency recommendations. The IEA calls therefore for full and immediate implementation of the recommendations.

    The Transport Working Group was formed on The 10th November 1999 to study all means of transport required for the installation of the LHC machine in the existing tunnel infrastructure of the LEP. The Groups' main aim is to assess the feasibility of transport propositions offered for the handling to be carried out in the new LHC environment. The working group is composed of Mechanical Engineers, Physicists and Transport Engineers, as well as specialists who are invited to the meetings for their advice on certain aspects of the forthcoming installation. In May 2001 the group mandate was revised to include all means of transport, including surface transport as well as that required in the tunnel. The installation phase requires the handling of approximately 100,000 tonnes of delicate experimental equipment with very strict limits in terms of acceleration and shock loading. This must be installed via vertical shafts up to 140 meters deep.

Sixty-four reproductive-aged women who underwent laparoscopic surgery for endometriosis received post-operative medical treatment with either GnRH agonist plus 17β-estradiol and norethisterone acetate (n = 28) or dienogest (n = 36) for 6 months. The pre- to post-treatment changes in pain were assessed using a visual analogue scale, and changes in quality-of-life and menopausal symptoms were measured by questionnaire. Visual analogue scale pain score decreased significantly for both treatments with no significant differences between groups. Neither physical, psychological, social, and environmental components of quality-of-life nor menopausal rating scale score were significantly different between the two groups. Bone mineral density at the lumbar spine declined significantly in both treatment groups (-2.5 % for GnRH agonist plus add-back and -2.3 % for dienogest), with no significant difference between the two groups. GnRH agonist and add-back therapy using 17β-estradiol and norethisterone acetate are as effective and tolerable as dienogest for the prevention of pelvic pain recurrence after laparoscopic surgery for endometriosis.

    Full Text Available Background: Omega-3 fatty acids and 5-hydroxytryptophan have been gaining attention as promising alternative treatment for depressive illness. These agents are given as as add on treatment to conventional antidepressant drugs. The present study was carried out to evaluate efficacy of omega-3 fatty acids versus 5-hydroxytryptophan as add on therapy in controlling suicidal ideation in depressive patients on sertraline.Methods: This was a prospective, open label, randomized, parallel group study conducted in department of Psychiatry. Ninety treatment naïve patients (18-65 years age were divided into 3 groups of 30 each. Group I: Sertraline, Group II: Sertraline plus omega-3 fatty acids, Group III: Sertraline plus 5-hydroxytryptophan. Suicidal ideations were assessed with Beck’s scale for suicidal ideation (BSI at weeks 0, 4 and 8. Data were analyzed using repeated measures ANOVA (SPSS version 20.0. Post hoc analysis was done using Bonferroni test.Results: Baseline parameters in patients of all groups were comparable. Administration of sertraline resulted in reduction of Beck’s scale for suicidal ideation scores as compared to baseline. Addition of omega-3 fatty acids and 5-hydroxytryptophan also showed reduction in BSI scores. Effect of sertraline monotherapy was more as compared to omega-3 fatty acids or 5-hydroxytryptophan as add on therapy, which was statistically significant (p value < 0.05.Conclusion: Both omega-3 fatty acids and 5-hydroxytryptophan produce significant effect in controlling suicidal ideations in patients with depression.

    The hopping process, which differs substantially from conventional transport processes in crystals, is the central process in the transport phenomena discussed in this book. Throughout the book the term ``hopping'' is defined as the inelastic tunneling transfer of an electron between two localized electronic states centered at different locations. Such processes do not occur in conventional electronic transport in solids, since localized states are not compatible with the translational symmetry of crystals.The rapid growth of interest in hopping transport has followed in the footsteps of the

  11. WASTE PACKAGE TRANSPORTER DESIGN

    Energy Technology Data Exchange (ETDEWEB)

    D.C. Weddle; R. Novotny; J. Cron

    1998-09-23

    The purpose of this Design Analysis is to develop preliminary design of the waste package transporter used for waste package (WP) transport and related functions in the subsurface repository. This analysis refines the conceptual design that was started in Phase I of the Viability Assessment. This analysis supports the development of a reliable emplacement concept and a retrieval concept for license application design. The scope of this analysis includes the following activities: (1) Assess features of the transporter design and evaluate alternative design solutions for mechanical components. (2) Develop mechanical equipment details for the transporter. (3) Prepare a preliminary structural evaluation for the transporter. (4) Identify and recommend the equipment design for waste package transport and related functions. (5) Investigate transport equipment interface tolerances. This analysis supports the development of the waste package transporter for the transport, emplacement, and retrieval of packaged radioactive waste forms in the subsurface repository. Once the waste containers are closed and accepted, the packaged radioactive waste forms are termed waste packages (WP). This terminology was finalized as this analysis neared completion; therefore, the term disposal container is used in several references (i.e., the System Description Document (SDD)) (Ref. 5.6). In this analysis and the applicable reference documents, the term ''disposal container'' is synonymous with ''waste package''.

    2013-01-01

    In humans, systemic heme homeostasis is achieved via coordinated regulation of heme synthesis, transport and degradation. Although the heme biosynthesis and degradation pathways have been well characterized, the pathways for heme trafficking and incorporation into hemoproteins remains poorly understood. In the past few years, researchers have exploited genetic, cellular and biochemical tools, to identify heme transporters and, in the process, reveal unexpected functions for this elusive group of proteins. However, given the complexity of heme trafficking pathways, current knowledge of heme transporters is fragmented and sometimes contradictory. This review seeks to focus on recent studies on heme transporters with specific emphasis on their functions during erythropoiesis. PMID:23415705

    Full Text Available ABSTRACT ABC transporters form the largest of all transporter families, and their structural study has made tremendous progress over recent years. However, despite such advances, the precise mechanisms that determine the energy-coupling between ATP hydrolysis and the conformational changes following substrate binding remain to be elucidated. Here, we present our thermodynamic analysis for both ABC importers and exporters, and introduce the two new concepts of differential-binding energy and elastic conformational energy into the discussion. We hope that the structural analysis of ABC transporters will henceforth take thermodynamic aspects of transport mechanisms into account as well.

  19. Embryonic epithelial membrane transporters.

    Science.gov (United States)

    Horster, M

    2000-12-01

    Embryonic epithelial membrane transporters are organized into transporter families that are functional in several epithelial organs, namely, in kidney, lung, pancreas, intestine, and salivary gland. Family members (subtypes) are developmentally expressed in plasma membranes in temporospatial patterns that are 1) similar for one subtype within different organs, like aquaporin-1 (AQP1) in lung and kidney; 2) different between subtypes within the same organ, like the amiloride-sensitive epithelial sodium channel (ENaC) in lung; and 3) apparently matched among members of different transporter families, as alpha-ENaC with AQP1 and -4 in lung and with AQP2 in kidney. Finally, comparison of temporal expression patterns in early embryonic development of transporters from different families [e.g., cystic fibrosis transmembrane conductance regulator (CFTR), ENaC, and outer medullary potassium channel] suggests regulatory activating or inactivating interactions in defined morphogenic periods. This review focuses on embryonic patterns, at the mRNA and immunoprotein level, of the following transporter entities expressed in epithelial cell plasma membranes: ENaC; the chloride transporters CFTR, ClC-2, bumetanide-sensitive Na-K-Cl cotransporter, Cl/OH, and Cl/HCO(3); the sodium glucose transporter-glucose transporter; the sodium/hydrogen exchanger; the sodium-phosphate cotransporter; the ATPases; and AQP. The purpose of this article is to relate temporal and spatial expression patterns in embryonic and in early postnatal epithelia to developmental changes in organ structure and function.

    Information on the emissions and energy consumption of different vehicles per transported amount of goods has up to last years been minimal. The unit emissions mean the amount of harmful compounds in the flue gases of a vehicle per service, time or energy unit. National three-year MOBILE 2-research program, started in 1999, determines the unit emissions of all the traffic sectors in Finland. VTT Building and Transport mainly carry out the research, but the Institute of Transportation Engineering of the Tampere University of Technology (TTKK) is responsible for a part of the research. The objective of the project is to create common rules for the determination of unit emissions values, and to determine the best possible values for Finnish conditions. Unit emission data is mainly needed for evaluation of the environmental impacts of production plants and other activities containing transportation of commodities. At the web sites of VTT Building and Transport there are about 60 pages of text and tables (about 4000 values) on unit emissions. The URL of the pages is http://www.vtt.fi/rte/projects/lipastoe/index.htm. These web pages present data on all the transportation sectors (road, railroad, water and air transportation), most of the materials concerning road transportation. Following compounds and values are included: CO, HC, NO x , particulates, SO 2 , CO 2 and energy consumption. Methane and nitrous oxide emissions values have also been presented

    1991-01-01

    Historically, the progression of IAEA Regulation revisions has always resulted in changes mainly for the better, in the way spent fuel is transported. The more recent regulatory changes have had a more pronounced effect on the way Nuclear Transport Limited (NTL) transports spent fuel. A Transport Management System has been established which not only ensures the Regulations and Package Approval requirements are met but also demonstrates that they are complied with. The system provides documented procedures for all levels of management. They cover a wide range of disciplines from the simplest of transport administration tasks to the more complex business of transport scheduling, reactor site operations and maintenance of packagings and associated equipment. NTL's Transport Management System is self regulatory. The clearly defined boundaries of responsibilities of the personnel carrying out documented procedures ensures non-conformities are minimised. When non-conformities do arise corrective actions are put into the system to prevent recurrence. The benefits of a formal Quality Management System are easily quantified. NTL have recognised the increased efficiency in spent fuel transport activities and the snowball effect it has had on other bodies. For example, approved suppliers have responded favourably to demands for better quality and Competent Authorities have expressed satisfaction after completing their compliance checks. (author)

    Soluble sugars serve five main purposes in multicellular organisms: as sources of carbon skeletons, osmolytes, signals, and transient energy storage and as transport molecules. Most sugars are derived from photosynthetic organisms, particularly plants. In multicellular organisms, some cells specialize in providing sugars to other cells (e.g., intestinal and liver cells in animals, photosynthetic cells in plants), whereas others depend completely on an external supply (e.g., brain cells, roots and seeds). This cellular exchange of sugars requires transport proteins to mediate uptake or release from cells or subcellular compartments. Thus, not surprisingly, sugar transport is critical for plants, animals, and humans. At present, three classes of eukaryotic sugar transporters have been characterized, namely the glucose transporters (GLUTs), sodium-glucose symporters (SGLTs), and SWEETs. This review presents the history and state of the art of sugar transporter research, covering genetics, biochemistry, and physiology-from their identification and characterization to their structure, function, and physiology. In humans, understanding sugar transport has therapeutic importance (e.g., addressing diabetes or limiting access of cancer cells to sugars), and in plants, these transporters are critical for crop yield and pathogen susceptibility.

    Purpose: In a liquid-metal cooled reactor, to reduce the waiting time of fuel handling apparatuses and shorten the fuel exchange time. Constitution: A fuel transporting machine is arranged between a reactor vessel and an out-pile storage tank, thereby dividing the transportation line of the pot for contracting fuel and transporting the same. By assuming such a construction, the flow of fuel transportation which has heretofore been carried out through fuel transportation pipes is not limited to one direction but the take-out of fuels from the reactor and the take-in thereof from the storage tank can be carried out constantly, and much time is not required for fuel exchange.

    A test was performed to determine whether transporting and handling the undulators makes any changes to their properties. This note documents the test. No significant changes to the test undulator were observed. After the LCLS undulators are tuned and fiducialized in the Magnetic Measurement Facility (MMF), they must be transported to storage buildings and transported to the tunnel. It has been established that the undulators are sensitive to temperature. We wish to know whether the undulators are also sensitive to the vibrations and shocks of transportation. To study this issue, we performed a test in which an undulator was measured in the MMF, transported to the tunnel, brought back to the MMF, and re-measured. This note documents the test and the results.

  15. Reducing Transport Intensity

    Banister, D. [University College London, London (United Kingdom); Stead, D. [OTB Research Institute, Delft University of Technology, Delft (Netherlands)

    2002-07-01

    In this paper transport intensity concerns the economic or energy efficiency of transport. The focus of the paper is the measurement and use of indicators of transport intensity. Most research has concentrated on the volume and distance measures, which show continuous increases over time, normally at a rate that is higher than the growth in Gross Domestic Product (GDP). It is argued that an additional element needs to be included, namely transport efficiency, which relates to modes, technologies, organisational structures, the use of resources and prices. The measurement of GDP also needs to be extended. Measures of economic and transport energy efficiency are applied to EU countries and contrasted with similar measures for the USA and Canada. The empirical evidence is then placed in the wider context of globalisation and economic change, and the case for real decoupling is made for both the freight and passenger sectors.

    Science.gov (United States)

    Nelson, N; Lill, H

    1994-11-01

    Uptake of neurotransmitters involves multiple transporters acting in different brain locations under different physiological conditions. The vesicular transporters are driven by a proton-motive force generated by a V-ATPase and their substrates are taken up via proton/substrate exchange. The plasma membrane transporters are driven by an electrochemical gradient of sodium generated by a Na+/K(+)-ATPase. Two distinct families of transporters were identified in this group. One cotransports sodium with glutamate and other amino acids and requires additionally an outwardly directed potassium gradient. The second cotransports sodium, chloride and a variety of neurotransmitters, including gamma-aminobutyric acid (GABA), glycine and monoamines. Genes and cDNA encoding several members of the latter family have been cloned and studied in detail. The structure and function as well as the evolutionary relationships among these neurotransmitter transporters are discussed.

    To allow cells to control their pH and bicarbonate levels, cells express bicarbonate transport proteins that rapidly and selectively move bicarbonate across the plasma membrane. Physical interactions have been identified between the carbonic anhydrase isoform, CAII, and the erythrocyte membrane Cl- /HCO3(-) anion exchanger, AE1, mediated by an acidic motif in the AE1 C-terminus. We have found that the presence of CAII attached to AE1 accelerates AE1 HCO3(-) transport activity, as AE1 moves bicarbonate either into or out of the cell. In efflux mode the presence of CAII attached to AE1 will increase the local concentration of bicarbonate at the AE1 transport site. As bicarbonate is transported into the cell by AE1, the presence of CAII on the cytosolic surface accelerates transport by consumption of bicarbonate, thereby maximizing the transmembrane bicarbonate concentration gradient experienced by the AE1 molecule. Functional and physical interactions also occur between CAII and Na+/HCO3(-) co-transporter isoforms NBC1 and NBC3. All examined bicarbonate transport proteins, except the DRA (SLC26A3) Cl-/HCO3(-) exchange protein, have a consensus CAII binding site in their cytoplasmic C-terminus. Interestingly, CAII does not bind DRA. CAIV is anchored to the extracellular surface of cells via a glycosylphosphatidyl inositol linkage. We have identified extracellular regions of AE1 and NBC1 that directly interact with CAIV, to form a physical complex between the proteins. In summary, bicarbonate transporters directly interact with the CAII and CAIV carbonic anhydrases to increase the transmembrane bicarbonate flux. The complex of a bicarbonate transporter with carbonic anhydrase forms a "Bicarbonate Transport Metabolon."

Following the analysis of the issue, and on the grounds of Kaizen's and Lean's method, the concept of continuous innovations is suggested as very useful for the development of transport. The potential of clusters as the source of logistic innovations in transport is emphasised. Methods: The discussion of the issue was preceded by the author's analysis of written sources on innovativeness, the evaluation of ratings of innovativeness as well as the analysis of rewarded innovative solutions in transport subsequent to the businesses participation in the programme of innovative solutions in transport. The role of innovation practical business operations is argued following the analysis of some strategic documents such as: 2011 White Paper and the Strategy for the Development of Transport by 2020 adopted by the Polish government in 2013. Aim: The aim of the article is to present the role and significance of the issue of logistic innovations in transport and to cite instances of practical solutions implemented by shipping companies, the solutions which resulted in measurable effects. Following the author's observation of the instances of innovative solutions as well as his analysis of the ratings of innovativeness, the article aims to present the conclusions as for the specific kinds of activities which are indispensable to foster innovativeness in transport. Conclusions: The conclusions derived from the author's analyses and observations show that logistic

    This issue of the 'Sustainable Transportation Monitor', published by the Centre for Sustainable Transportation located in Mississauga, Ontario, reports on key findings from a project involving children and transportation in the Halton and Peel regions of Ontario, recently completed by the Centre. Excerpts from the report summarized in this issue include data on children's travel in Halton and Peel, and a discussion on possible contribution of transport practices to the growing incidence of obesity among Canadian children. Results of the study indicate that until about age 18, travel by children on schooldays is dominated by the journey to and from school. School bus is the choice of 28 per cent, and passenger car by 23 per cent among 11-to-14- year-olds; the share of travel by car is larger for older young people and also likely larger among 6-to-10-year-olds. Physical inactivity has been highlighted as the contributing factor to excess body weight and obesity in this, and other studies. Data collected for this study corroborates the findings of other studies by showing a positive correlation between obesity and transport energy use in 18 affluent countries, suggesting that a high level of use of motorized transport contributes to inactivity and body weight gain. Several alternate means of transportation, with the potential to combat obesity, are proposed. 46 refs.

    The relationship between globalisation and traffic volume is a complex one for many reasons. The transport sector is influenced by a variety of developments at different scales. Increasing incomes, more leisure time, new technology and a greying population are only a few examples of trends that are influencing future developments in transport and traffic. The future of transport is thus very uncertain. The project GITAGE (Globalisation, International Transport and the Global Environment) is being conducted by the Vrije Universteit Amsterdam, TRAIL (Delft University), the Netherlands Central Planning Bureau (CPB) and IVM (Institute for Environmental Studies). It was within this context that a layered assessment model was used to attempt to chart the possible influence of globalisation on the transport sector in terms of transport flows: and CO2 emissions. Four future scenarios at different scales (Global, European and Netherlands) produced virtually everywhere a (steep) rise in transport and emissions. The introduction of focused policy can change this picture. In fact, however, in most cases only a combination of stringent environmental policy and an environmentally conscious vision of the future can lead to a decline in CO2 emissions between 1995 and 2020.

    A one-dimensional tokamak transport code is described which simulates a plasma discharge using a fluid model which includes power balances for electrons and ions, conservation of mass, and Maxwell's equations. The modular structure of the code allows a user to add models of various physical processes which can modify the discharge behavior. Such physical processes treated in the version of the code described here include effects of plasma transport, neutral gas transport, impurity diffusion, and neutral beam injection. Each process can be modeled by a parameterized analytic formula or at least one detailed numerical calculation. The program logic of each module is presented, followed by detailed descriptions of each subroutine used by the module. The physics underlying the models is only briefly summarized. The transport code was written in IBM FORTRAN-IV and implemented on IBM 360/370 series computers at the Oak Ridge National Laboratory and on the CDC 7600 computers of the Magnetic Fusion Energy (MFE) Computing Center of the Lawrence Livermore Laboratory. A listing of the current reference version is provided on accompanying microfiche

    The recent announcement by the Australian Government of funding for a dramatic increase in supply infrastructure for Compressed Natural Gas (CNG) powered vehicles has shored up predictions that natural gas will achieve a thirty-fold increase in its share of the Australian transport energy market by 2015. This projection, would put sales of natural gas for transport fuel in the year 2014/15 at about 10% of current retail sales across the nation. In the general transport sector, the lower particulate and noise pollution, compared with diesel-powered vehicles, is a significant advantage

    Until recently the formal statistical mechanical approach offered no practicable method for computing the transport coefficients of liquids, and so most practitioners had to resort to empirical fitting formulas. This has now changed, as demonstrated in this innovative monograph. The author presents and applies new methods based on statistical mechanics for calculating the transport coefficients of simple and complex liquids over wide ranges of density and temperature. These molecular theories enable the transport coefficients to be calculated in terms of equilibrium thermodynamic properties, and the results are shown to account satisfactorily for experimental observations, including even the non-Newtonian behavior of fluids far from equilibrium.

    Use of gonadotropin-releasing hormone agonists (GnRHa) to treat endometriosis can cause mood and vasomotor side effects. "Add-back therapy," the combination of low-dose hormones, limits side effects but research is limited to adults. We sought to characterize quality of life (QOL) before treatment and to compare an add-back regimen of norethindrone acetate (NA) with conjugated estrogens (CEE) to NA alone for preventing side effects of GnRHa therapy in female adolescents with endometriosis. Twelve-month double-blind, placebo-controlled trial. Pediatric Gynecology clinic in Boston, Massachusetts. Fifty female adolescents (aged 15-22 years) with surgically confirmed endometriosis initiating treatment with GnRHa. Subjects were randomized to: NA (5 mg/d) with CEE (0.625 mg/d) or NA (5 mg/d) with placebo. All subjects received leuprolide acetate depot every 3 months. The Short Form-36 v2 Health Survey, Beck Depression Inventory II, and Menopause Rating Scale were completed at repeated intervals. At baseline, subjects reported impaired physical health-related QOL compared with national norms (all P endometriosis initiating GnRHa therapy have impaired QOL. Treatment with GnRHa combined with add-back therapy led to improved QOL, with no worsening of mood or menopausal side effects.

    Full Text Available ADHD is the most common and most studied neurodevelopmental problem. Recent statistics from the CDC state that 11% approximately 1 out of every 9 children in the US and 1 in 5 high school boys are diagnosed with ADHD. Lacking from treatment is an interdisciplinary knowledge-based strategy to intervention with child public health concerns addressed the educational system. This study is based on previous findings that ADHD children possess underactivity between sub-cortical and cortical regions. An imbalance of activity or arousal in one area can result in functional disconnections similar to that seen in split-brain patients. As ADD/ADHD children exhibit deficient performance on tests measuring perceptual laterality, evidence of weak laterality or failure to develop laterality has been found across various modalities (auditory, visual, tactile resulting in abnormal cerebral organization and associated dysfunctional specialization needed for lateralized processing of language and non-language function. This pilot study examines groups of ADD/ADHD and control elementary school children all of whom were administered all the subtests of the Wechsler Individual Achievement Tests, the Brown Parent Questionnaire, and given objective performance measures on tests of motor and sensory coordinative abilities. Results measured after a 12-week remediation program aimed at increasing the activity of the hypothesized underactive right hemisphere function, yielded significant improvement of greater than two years in grade level in all domains except in mathematical reasoning. The treated group also displayed a significant improvement in behavior with a reduction in Brown scale behavioral scores. Non-treated control participants did not exhibit significant differences during the same 12-week period in academic measurements, but did so when compared to the treated group. Results are discussed in the context of the concept of functional disconnectivity in ADD

    Type 2 diabetes treatment primarily focuses on reducing hyperglycemia, including postprandial glucose excursions. Hypoglycemic agents are used clinically to lower fasting and postprandial glucose. Metformin is the first-line therapy; however, if metformin is inadequate then 'add-on' hypoglycemic agents are implemented. Postmeal exercise has been shown to lower postprandial glucose. The aim of this study was to assess if postmeal exercise provides additional glucose-lowering benefit, beyond medication alone, in those on add-on hypoglycemic agents. Postprandial glucose excursions in eight participants with type 2 diabetes (Age: 60±10.7, HbA 1C : 7.9±2.3) being treated with add-on hypoglycemic agents were assessed during both drug-treated sedentary and drug-treated postmeal exercise conditions. Continuous glucose monitoring was used to assess peak and area under the glucose curve (AUC) during exercise, as well as peak within a 2-h time window, 2-h total and 2-h incremental AUC after a standardized breakfast meal. Postmeal exercise consisted of 3×10-min intervals of treadmill walking at 50% maximal oxygen uptake. Glucose peak (drug only: 13.8±3.7, drug/exercise: 9.9±2.7mmol/L; p=0.02) and AUC (drug only: 500±136, drug/exercise: 357±89mmol/L×40min; p=0.03) were reduced during postmeal exercise. Breakfast 2-h incremental AUC was also reduced (drug only: 585±291, drug/exercise: 330±294; p=0.047). Post-breakfast exercise lowered glucose during the exercise bout, although this effect was not sustained on later meals. Copyright © 2017 Elsevier B.V. All rights reserved.

    Patient-reported outcomes (PRO) such as health-related quality-of-life (HRQoL) belong to the most important criteria for the evaluation of medical therapies in clinical trials or practice-based benefit assessments. This study, therefore, revisited results of an earlier published clinical trial investigating the effects of the herbal drug preparation from the roots of Pelargonium sidoides EPs 7630, administered as add-on therapy in patients suffering from chronic obstructive pulmonary disease (COPD), with respect to HRQoL and other PRO. A total of 199 adults diagnosed with COPD stages II/III and receiving standard treatment according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) were randomly assigned to add-on therapy with EPs 7630 or placebo for 24 weeks. HRQoL (disease-specific St. George's Respiratory Questionnaire, SGRQ; current HRQoL state according to the EuroQuol visual analog scale, EQ VAS) and PRO (Integrative Medicine Outcomes Scale, IMOS; Integrative Medicine Patient Satisfaction Scale, IMPSS; symptom severity score of cough, sputum production and sternal pain while coughing; duration of inability to work) were assessed at each study visit or documented daily by the patient in a patient diary, respectively. At week 24, all HRQoL and PRO measures showed a more pronounced improvement under EPs 7630 than under placebo (EQ VAS, p Add-on therapy with EPs 7630 led to an improvement in HRQoL and other PRO in adult patients with COPD compared to placebo while showing a good long-term tolerability.

    Bone scintigraphy is usually obtained as a whole-body scan producing 2 images: an anterior view and a posterior view. Sometimes abnormal findings in the spine are difficult to distinguish on whole-body bone scans. SPECT/CT may be performed to localize and interpret a lesion correctly and to help differentiate between benign and metastatic lesions. The assessment of whether SPECT/CT is needed is usually made by a physician. The aim of this study was to evaluate our new routine for nuclear medicine technologists to determine when to add SPECT/CT to whole-body bone scintigraphy. A 3-part educational course was developed for the nuclear medicine technologists. The first part was to learn criteria for when SPECT/CT should be added to a whole-body bone scan. The second part was to review a selection of training whole-body bone scans illustrating the criteria. The third part was to pass a test of whether whole-body bone scans should be supplemented by SPECT/CT. The nuclear medicine technologists and the physicians agreed that SPECT/CT was required in 63 cases and not required in 27 cases. The resulting percentage agreement was 90%, and the κ value was 0.77. There was disagreement in 10 cases. In 6 of these cases only the nuclear medicine technologists wanted to add SPECT/CT, and in 4 of these cases only the physicians wanted to add SPECT/CT. After participating in the training course developed in this project, the nuclear medicine technologists were able to decide whether a SPECT/CT study is needed. An implication of this result is that the effectiveness of the nuclear medicine department should be improved after our new routine is implemented. The successful outcome of this project may stimulate departments to take on similar quality-improvement projects in the future.

    The automatic tendency to attend to and focus on substance-related cues in the environment (attentional bias), has been found to contribute to the persistence of addiction. Attentional bias modification (ABM) interventions might, therefore, contribute to treatment outcome and the reduction of relapse rates. Based on some promising research findings, we designed a study to test the clinical relevance of ABM as an add-on component of regular intervention for alcohol and cannabis patients. The current protocol describes a study which will investigate the effectiveness and cost-effectiveness of a newly developed home-delivered, multi-session, internet-based ABM (iABM) intervention as an add-on to treatment as usual (TAU). TAU consists of cognitive behavioural therapy-based treatment according to the Dutch guidelines for the treatment of addiction. Participants (N = 213) will be outpatients from specialized addiction care institutions diagnosed with alcohol or cannabis dependency who will be randomly assigned to one of three conditions: TAU + iABM; TAU + placebo condition; TAU-only. Primary outcome measures are substance use, craving, and rates of relapse. Changes in attentional bias will be measured to investigate whether changes in primary outcome measures can be attributed to the modification of attentional bias. Indices of cost-effectiveness and secondary physical and psychological complaints (depression, anxiety, and stress) are assessed as secondary outcome measures. This randomized control trial will be the first to investigate whether a home-delivered, multi-session iABM intervention is (cost-) effective in reducing relapse rates in alcohol and cannabis dependency as an add-on to TAU, compared with an active and a waiting list control group. If proven effective, this ABM intervention could be easily implemented as a home-delivered component of current TAU. Netherlands Trial Register, NTR5497 , registered on 18th September 2015.

    The purpose of this report is to develop and analyze the engineered barrier system (EBS) radionuclide transport abstraction model, consistent with Level I and Level II model validation, as identified in ''Technical Work Plan for: Near-Field Environment and Transport: Engineered Barrier System: Radionuclide Transport Abstraction Model Report Integration'' (BSC 2005 [DIRS 173617]). The EBS radionuclide transport abstraction (or EBS RT Abstraction) is the conceptual model used in the total system performance assessment for the license application (TSPA-LA) to determine the rate of radionuclide releases from the EBS to the unsaturated zone (UZ). The EBS RT Abstraction conceptual model consists of two main components: a flow model and a transport model. Both models are developed mathematically from first principles in order to show explicitly what assumptions, simplifications, and approximations are incorporated into the models used in the TSPA-LA. The flow model defines the pathways for water flow in the EBS and specifies how the flow rate is computed in each pathway. Input to this model includes the seepage flux into a drift. The seepage flux is potentially split by the drip shield, with some (or all) of the flux being diverted by the drip shield and some passing through breaches in the drip shield that might result from corrosion or seismic damage. The flux through drip shield breaches is potentially split by the waste package, with some (or all) of the flux being diverted by the waste package and some passing through waste package breaches that might result from corrosion or seismic damage. Neither the drip shield nor the waste package survives an igneous intrusion, so the flux splitting submodel is not used in the igneous scenario class. The flow model is validated in an independent model validation technical review. The drip shield and waste package flux splitting algorithms are developed and validated using experimental data.

    We developed a full-ring ;add-on PET; prototype which is brain-dedicated and consists of a RF-head coil with four-layer depth-of-interaction (DOI) PET detectors for integrated PET/MRI in order to evaluate performance of our previously proposed add-on PET system and to investigate the mutual influences between the individual PET and MRI modalities when they are integrated in simultaneous measurements. In this add-on PET prototype, the DOI detectors are mounted on the head coil and close to the patient head. As a result, higher sensitivity and higher spatial resolution can be achieved for the integrated PET/MRI, compared with conventional whole body PET/MRI systems. In addition, implementation cost can be reduced, tuning of the RF-coil can be optimized and PET and MRI images can be obtained simultaneously in exactly the same positions. Specifically, the full-ring prototype consists of eight DOI-PET detectors and a birdcage type head coil of a 3T MRI. The radius of the PET ring is 123.9 mm. The distance from the center to the RF-coil elements is 130.5 mm. The scintillator blocks consist of lutetium-yttrium oxyorthosilicate scintillators arranged in 19×6×4 layers with reflectors inserted between them. The size of each crystal element is 2.0 mm×2.0 mm ×5.0 mm. We evaluated performance of the full-ring prototype in simultaneous measurements of the integrated PET/MRI. We obtained spatial resolutions of 2.3 mm at the center of the field-of-view (FOV) and lower than 3.5 mm in the whole FOV. The energy resolution of 19.4% was obtained for 511 keV gamma-rays. In addition, we observed no degradation of PET performance caused by the MRI measurement. The signal-to-noise ratio (SNR) of the MRI image was 209.4 in simultaneous measurements with the PET. The maximum ΔB0 and maximum difference of the secondary magnetic field due to the eddy current effect were smaller than 0.8 ppm and ±5.0 μT, respectively. We concluded that sufficient spatial resolution and detector

    Transport contributes to several environmental problems such as climate change, air emissions and noise and is at the same time favoured by significant subsidies. An EEA report identifies European transport subsidies worth at least EUR 270 to 290 billion a year. Road transport receives EUR 125 billion in annual subsidies, most of it as infrastructure subsidies, assuming that taxes on road transport are not regarded as contributions to finance infrastructure. Aviation, as the mode with the highest specific climate impact, gets significant subsidies in the form of preferential tax treatment, in particular exemptions from fuel tax and VAT, which add up to EUR 27 to 35 billion per year. Rail is subsidised with EUR 73 billion per year and benefits the most from other on-budget subsidies. For water-borne transport, EUR 14 to 30 billion in subsidies have been identified. (orig.)

    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

    This report documents the emergency preparedness Hazards Assessment for the offsite transportation of hazardous material from the Hanford Site. The assessment is required by the US Department of Energy (DOE) Order 151.1. Offsite transportation accidents are categorized using the DOE system to assist communication within the DOE and assure that appropriate assistance is provided to the people in charge at the scene. The assistance will initially include information about the load and the potential hazards. Local authorities will use the information to protect the public following a transportation accident. This Hazards Assessment will focus on the material being transported from the Hanford Site. Shipments coming to Hanford are the responsibility of the shipper and the carrier and, therefore, are not included in this Hazards Assessment, unless the DOE elects to be the shipper of record

    The existing U.S. hub-and-spoke air transportation system is reaching saturation. Major aspects of the current system, such as capacity, safety, mobility, customer satisfaction, security, communications, and ecological effects, require improvements. The changing dynamics - increased presence of general aviation, unmanned autonomous vehicles, military aircraft in civil airspace as part of homeland defense - contributes to growing complexity of airspace. The system has proven remarkably resistant to change. NASA Langley Research Center and the National Institute of Aerospace conducted a workshop on Transportation Network Topologies on 9-10 December 2003 in Williamsburg, Virginia. The workshop aimed to examine the feasibility of traditional methods for complex system analysis and design as well as potential novel alternatives in application to transportation systems, identify state-of-the-art models and methods, conduct gap analysis, and thus to lay a foundation for establishing a focused research program in complex systems applied to air transportation.

    Transportation takes a considerable and increasing fraction of the energy use worldwide, and more than half the oil consumption. By far the largest part is used by cars powered by internal combustion engines. The advantage of using internal combustion engines is that the energy density of liquid fuels is extremely high. The disadvantage is that gasoline and diesel engines have a poor performance: 20 to 25% only. How does this compare with electric cars? What are the alternative transportation systems and their efficiencies anyway? In this lecture we analyse the efficiency of various transport systems, using elementary physics principles. We will look at cars, buses, trains and TGVs, ships and aircraft. In addition, the efficiency of human powered vehicles will be considered. New and promising developments in the field of Intelligent Transportation Systems, like Cooperative Adaptive Cruise Control, are also discussed.

    A discomforting reality has materialized on the transportation scene: our existing air and ground infrastructures will not scale to meet our nation's 21st century demands and expectations for mobility, commerce, safety, and security. The consequence of inaction is diminished quality of life and economic opportunity in the 21st century. Clearly, new thinking is required for transportation that can scale to meet to the realities of a networked, knowledge-based economy in which the value of time is a new coin of the realm. This paper proposes a framework, or topology, for thinking about the problem of scalability of the system of networks that comprise the aviation system. This framework highlights the role of integrated communication-navigation-surveillance systems in enabling scalability of future air transportation networks. Scalability, in this vein, is a goal of the recently formed Joint Planning and Development Office for the Next Generation Air Transportation System. New foundations for 21st thinking about air transportation are underpinned by several technological developments in the traditional aircraft disciplines as well as in communication, navigation, surveillance and information systems. Complexity science and modern network theory give rise to one of the technological developments of importance. Scale-free (i.e., scalable) networks represent a promising concept space for modeling airspace system architectures, and for assessing network performance in terms of scalability, efficiency, robustness, resilience, and other metrics. The paper offers an air transportation system topology as framework for transportation system innovation. Successful outcomes of innovation in air transportation could lay the foundations for new paradigms for aircraft and their operating capabilities, air transportation system architectures, and airspace architectures and procedural concepts. The topology proposed considers air transportation as a system of networks, within which

    During pregnancy, it is not always possible to identify maternal or foetal risk factors. Infants requiring specialised medical care are not always born in centres providing intensive care and will need to be transferred to a referral centre where intensive care can be provided. Therefore Neonatal Transport needs to be considered as part of the organisation of perinatal health care. The aim of Neonatal Transport is to transfer a newborn infant requiring intensive care to a centre where specialised resources and experience can be provided for the appropriate assessment and continuing treatment of a sick newborn infant. Intrauterine transfer is the ideal mode of transport when the birth of an infant with risk factors is diagnosed. Unfortunately, not all problems can be detected in advance with enough time to safely transfer a pregnant woman. Around 30- 50% of risk factors will be diagnosed during labour or soon after birth. Therefore, it is important to have the knowledge and resources to resuscitate and stabilise a newborn infant, as well as a specialised neonatal transport system. With this specialised transport it is possible to transfer newly born infants with the same level of care that they would receive if they had been born in a referral hospital, without increasing their risks or affecting the wellbeing of the newborn. The Standards Committee of the Spanish Society of Neonatology reviewed and updated recommendations for intrauterine transport and indications for neonatal transfer. They also reviewed organisational and logistic factors involved with performing neonatal transport. The Committee review included the type of personnel who should be involved; communication between referral and receiving hospitals; documentation; mode of transport; equipment to stabilise newly born infants; management during transfer, and admission at the referral hospital.

    Characterization of the cross-field energy transport in magnetic confinement experiments in a manner applicable to the accurate assessment of future machine performance continues to be a challenging goal. Experimental results from the DIII-D tokamak in the areas of dimensionless scaling and non-diffusive transport represent progress toward this goal. Dimensionless scaling shows how beneficial the increase in machine size and magnetic field is for future devices. The experiments on DIII-D are the first to determine separately the electron and ion scaling with normalized gyroradius ρ * ; the electrons scale as expected from gyro-Bohm class theories, while the ions scale consistent with the Goldston empirical scaling. This result predicts an increase in transport relative to Bohm diffusion as ρ * decreases in future devices. The existence of distinct ρ * scalings for ions and electrons cautions against a physical interpretation of one-fluid or global analysis. The second class of experiments reported here are the first to demonstrate the existence of non-diffusive energy transport. Electron cyclotron heating was applied at the half radius; the electron temperature profile remains substantially peaked. Power balance analysis indicates that heat must flow in the direction of increasing temperature, which is inconsistent with purely diffusive transport. The dynamics of electron temperature perturbations indicate the presence in the heat flux of a term dependent on temperature rather than its gradient. These two observations strongly constrain the types of models which can be applied to cross-field heat transport

    ABC transporters constitute one of the largest protein families found in all living organisms. ABC transporters are driven by ATP hydrolysis and can act as exporters as well as importers. The plant genome encodes for more than 100 ABC transporters, largely exceeding that of other organisms. In Arabidopsis, only 22 out of 130 have been functionally analyzed. They are localized in most membranes of a plant cell such as the plasma membrane, the tonoplast, chloroplasts, mitochondria and peroxisomes and fulfill a multitude of functions. Originally identified as transporters involved in detoxification processes, they have later been shown to be required for organ growth, plant nutrition, plant development, response to abiotic stresses, pathogen resistance and the interaction of the plant with its environment. To fulfill these roles they exhibit different substrate specifies by e.g. depositing surface lipids, accumulating phytate in seeds, and transporting the phytohormones auxin and abscisic acid. The aim of this review is to give an insight into the functions of plant ABC transporters and to show their importance for plant development and survival. PMID:22303277

    1977-01-01

    Twenty years of almost accident-free transport of nuclear materials is pointed to as evidence of a fundamentally correct approach to the problems involved. The increased volume and new technical problems in the future will require extension of these good practices in both regulations and packaging. The general principles of safety in the transport of radioactive materials are discussed first, followed by the transport of spent fuel and of radioactive waste. The security and physical protection of nuclear shipments is then treated. In discussing future problems, the question of public understanding and acceptance is taken first, thereafter transport safeguards and the technical bases for the safety regulations. There is also said to be a need for a new technology for spent fuel casks, while a re-examination of the IAEA transport standards for radiation doses is recommended. The IAEA regulations regarding quality assurance are said to be incomplete, and more information is required on correlations between engineering analysis, scale model testing and full scale crash testing. Transport stresses on contents need to be considered while administrative controls have been neglected. (JIW)

    2014-12-01

    Skin melanocytes and ocular pigment cells contain specialized organelles called melanosomes, which are responsible for the synthesis of melanin, the major pigment in mammals. Defects in the complex mechanisms involved in melanin synthesis and regulation result in vision and pigmentation deficits, impaired development of the visual system, and increased susceptibility to skin and eye cancers. Ion transport across cellular membranes is critical for many biological processes, including pigmentation, but the molecular mechanisms by which it regulates melanin synthesis, storage, and transfer are not understood. In this review we first discuss ion channels and transporters that function at the plasma membrane of melanocytes; in the second part we consider ion transport across the membrane of intracellular organelles, with emphasis on melanosomes. We discuss recently characterized lysosomal and endosomal ion channels and transporters associated with pigmentation phenotypes. We then review the evidence for melanosomal channels and transporters critical for pigmentation, discussing potential molecular mechanisms mediating their function. The studies investigating ion transport in pigmentation physiology open new avenues for future research and could reveal novel molecular mechanisms underlying melanogenesis.

  4. Transportation of radioactive materials in Sweden

    International Nuclear Information System (INIS)

    Ericsson, A.M.

    1979-06-01

    This report is designed to calculate the total risk due to shipping radioactive materials in Sweden. The base case developed is the shipment model that is used now or the best estimate for expected shipments. The model for the calculations and the computer program used has been developed at the Sandia Laboratories, Albuquerque, N.M., USA and is the same that was used for the NUREG-0170 study. The results from the calculations show an annual expected population dose of 30 person-rem due to normal transport conditions. The annual expected dose from accidents were calculated to be between 2.3-20.8 person rem. The higher figure represents the case where plutonium is shipped back to Sweden from reprocessing plants abroad in the form of PuO2 and the lower figure represent the case when plutonium is shipped back in the form of mixed oxide fuel. The total additional population dose in Sweden due to both normal and accident conditions in the transportation of radioactive materials will be 30 - 50 person rem/year. Compared to the natural background radiation that is 8x10 5 person rem per year in Sweden, this figure is very low. If converted to latent cancer fatalities this population dose will add approximately 3.5x10 3 cancers each year. The consequences due to accidents have been calculated and are discussed separately from their probabilities. The most severe accident that was found was an accident involving PuO 2 . This accident would give 82 400 rem as a maximum individual dose and 8.1x10 5 person rem as a population dose. (Auth.)

    Background. Documented trends in health-related risk behaviors among US adolescents have remained high over time. Studies indicate relationships among mutual friends are a major influence on adolescents' risky behaviors. Social Network Analysis (SNA) can help understand friendship ties affecting individual adolescents' engagement in these behaviors. Moreover, a systematic literature review can synthesize findings from a range of studies using SNA, as well as assess these studies' methodological quality. Review findings also can help health educators and promoters develop more effective programs. Objective. This review systematically examined studies of the influence of friendship networks on adolescents' risk behaviors, which utilized SNA and the Add Health data (a nationally representative sample). Methods. We employed the Matrix Method to synthesize and evaluate 15 published studies that met our inclusion and exclusion criteria, retrieved from the Add Health website and 3 major databases (Medline, Eric, and PsycINFO). Moreover, we assigned each study a methodological quality score (MQS). Results. In all studies, friendship networks among adolescents promoted their risky behaviors, including drinking alcohol, smoking, sexual intercourse, and marijuana use. The average MQS was 4.6, an indicator of methodological rigor (scale: 1-9). Conclusion. Better understanding of risky behaviors influenced by friends can be useful for health educators and promoters, as programs targeting friendships might be more effective. Additionally, the overall MQ of these reviewed studies was good, as average scores fell above the scale's mid-point.

    The multichannel analyzer is the heart of most experimental measurements. Today, it becomes popular and convenient. It can play a role of getting, processing data and easily interfacing to PC. Some standard-alone multichannel analysis systems can be replaced by Add-on MCA card. Especially, MCA card is necessary for application in nuclear physics research. The main aim of this sub-project is to focus on a design and construction of an 8K-MCA Add-on served for studying nuclear structure, for development of Gamma spectroscopy system, and for a production of low-cost electronics instruments as well. Some experimental results were obtained through the aforementioned card combining with other needed functional analog units. A multichannel data processing (MCD) circuit for nuclear spectroscopy application was developed using a field programmable gate arrays (FPGA) as the central processing element. In addition to the first role, A 13-bit analog-to-digital converter (8k ADC) circuit for nuclear spectroscopy application was also developed using a successive approximation ADC with a control of FPGA technology. The FPGA operates a program that builds the distributed functions of data collected by the ADC and then corrects the ADC differential non-linearity (DNL) via the sliding scale method. The acquisition routine runs in 3.7μ s. the conversion time is approximated 2.2μ s, and the integral non-linearity ≤ 0.14%. (author)

    Objective Within the social determinants of mental health framework, this article investigated whether children with ASD who have older siblings are less likely to experience depression, anxiety, behavior problems or have ADD/ADHD after controlling for standard social determinants of mental health such as household income, parental education and adverse childhood experiences (ACEs). Methods Using the National Survey of Children's Health 2011-2012, children with ASD spectrum disorders (n = 1624) were categorized into three groups: only child, oldest child and has older siblings. Design corrected cross-tabulations, univariate and multivariate logistic regressions were estimated. Results The three groups of children with ASD were comparable in demographic characteristics (except age), ACEs, and parent-reported ASD severity. Children with ASD who had older siblings were significantly less likely to experience depression, anxiety or behavior problems. They were also less likely to have been diagnosed with ADD or ADHD. Adjusted odds ratios ranged from 0.12 to 0.53 indicating robust associations. Conclusions for Practice Children with ASD who have older siblings were less likely to have comorbid mental health disorders than other children with ASD. Conversely, oldest and only children with ASD were at increased risk for these disorders. Further research is needed to understand how this protection is conferred on children with ASD, and whether it can be adapted into interventions for only and oldest children with ASD.

    Full Text Available Background. Documented trends in health-related risk behaviors among US adolescents have remained high over time. Studies indicate relationships among mutual friends are a major influence on adolescents’ risky behaviors. Social Network Analysis (SNA can help understand friendship ties affecting individual adolescents’ engagement in these behaviors. Moreover, a systematic literature review can synthesize findings from a range of studies using SNA, as well as assess these studies’ methodological quality. Review findings also can help health educators and promoters develop more effective programs.Objective. This review systematically examined studies of the influence of friendship networks on adolescents’ risk behaviors, which utilized SNA and the Add Health data (a nationally representative sample.Methods. We employed the Matrix Method to synthesize and evaluate 15 published studies that met our inclusion and exclusion criteria, retrieved from the Add Health website and 3 major databases (Medline, Eric, and PsycINFO. Moreover, we assigned each study a methodological quality score (MQS.Results. In all studies, friendship networks among adolescents promoted their risky behaviors, including drinking alcohol, smoking, sexual intercourse, and marijuana use. The average MQS was 4.6, an indicator of methodological rigor (scale: 1–9.Conclusion. Better understanding of risky behaviors influenced by friends can be useful for health educators and promoters, as programs targeting friendships might be more effective. Additionally, the overall MQ of these reviewed studies was good, as average scores fell above the scale’s mid-point.

    Monotherapy with pegylated interferon-α (Peg-IFNα) or the nucleos(t)ide analogs (NA) currently approved for treating chronic hepatitis B (CHB) has limited efficacy. Studies on the combination of Peg-IFNα/NA have shown conflicting results. We investigated whether sequentially adding on Peg-IFNα to tenofovir enhances serological response rates. Treatment-naïve, hepatitis B envelope antigen (HBeAg)-positive CHB patients with moderately elevated alanine aminotransferase (ALT; 48-200 IU/mL) were started on tenofovir (300 mg/day) and enrolled at week 12 in a 1:1 ratio to either receive Peg-IFNα2b add-on (1.5 μg/kg/week) from week 12 to 36 (n = 53) or continue tenofovir monotherapy (n = 53). Both treatment arms received tenofovir consolidation therapy until week 72. The primary end-point was HBeAg loss at week 72. At week 72, the rate of HBeAg loss was higher in the Peg-IFNα2b add-on group (35.8%) compared to the tenofovir monotherapy group (17%) (P = 0.028; odds ratio, 2.73, 95% confidence interval, 1.09-6.79), and considerably higher in patients with a baseline hepatitis B virus (HBV)-DNA level >6 log IU/mL (32.6% vs 11.4%; P = 0.021). Rates of HBV-DNA loss (77.4% vs 71.7%; P = 0.51), ALT normalization (62.3% vs 52.8%; P = 0.32), and sustained virologic response (20.8% vs 11.3%; P = 0.18) at week 72 were comparable between the two groups. Significantly more patients in the add-on group had >3 log HBV-DNA reduction at week 36 (92.5% vs 66%; P = 0.001). Four patients treated with Peg-IFNα2b add-on achieved hepatitis B surface antigen (HBsAg) loss compared with one patient receiving tenofovir monotherapy. Decline of HBV-DNA of >2 log at week 4 led to higher HBeAg loss at week 72, independent of treatment arm. No patient had treatment-related adverse effects requiring treatment discontinuation. Twenty-four weeks of Peg-IFNα2b as an add-on sequential regimen to tenofovir is safe and resulted in greater loss of HBeAg and HBs

    In this paper, problems of transportation of nuclear spent fuel to reprocessing plants are discussed. The solutions proposed are directed toward the achievement of the transportation as economic and safe as possible. The increase of the nuclear power plants number in the USSR and the great distances between these plants and the reprocessing plants involve an intensification of the spent fuel transportation. Higher burnup and holdup time reduction cause the necessity of more bulky casks. In this connection, the economic problems become still more important. One of the ways of the problem solution is the development of rational and cheap cask designs. Also, the enforcement in the world of the environmental and personnel health protection requires to increase the transportation reliability and safety. The paper summarizes safe transportation rules with clarifying the following questions: the increase of the transport unit quantity of the spent fuel; rational shipment organization that minimizes vehicle turnover cycle duration; development of the reliable calculation methods to determine strength, thermal conditions and nuclear safety of transport packaging as applied to the vehicles of high capacity; maximum unification of vehicles, calculation methods and documents; and cask testing on models and in pilot scale on specific test rigs to assure that they meet the international safe fuel shipment rules. Besides, some considerations on the choice and use of structural materials for casks are given, and problems of manufacturing such casks from uranium and lead are considered, as well as problems of the development of fireproof shells, control instrumentation, vehicles decontamination, etc. All the problems are considered from the point of view of normal and accidental shipment conditions. Conclusions are presented [ru

    This Greenpeace report shows: nuclear materials transport is an extremely hazardous business. There is no safe protection against accidents, kidnapping, or sabotage. Any moment of a day, at any place, a nuclear transport accident may bring the world to disaster, releasing plutonium or radioactive fission products to the environment. Such an event is not less probable than the MCA at Chernobyl. The author of the book in hand follows the secret track of radioactive materials around the world, from uranium mines to the nuclear power plants, from reprocessing facilities to the waste repositories. He explores the routes of transport and the risks involved, he gives the names of transport firms and discloses incidents and carelessness, tells about damaged waste drums and plutonium that 'disappeared'. He also tells about worldwide, organised resistance to such nuclear transports, explaining the Greenpeace missions on the open sea, or the 'day X' operation at the Gorleben site, informing the reader about protests and actions for a world freed from the threat of nuclear energy.

    Phosphorene, a novel elemental 2D semiconductor, possesses fascinating chemical and physical properties which are distinctively different from other 2D materials. The rapidly growing applications of phosphorene in nano/optoelectronics and thermoelectrics call for comprehensive studies of thermal transport properties. In this Review, based on the theoretical and experimental progresses, the thermal transport properties of single-layer phosphorene, multilayer phosphorene (nanofilms), and bulk black phosphorus are summarized to give a general view of the overall thermal conductivity trend from single-layer to bulk form. The mechanism underlying the discrepancy in the reported thermal conductivity of phosphorene is discussed by reviewing the effect of different functionals and cutoff distances on the thermal transport evaluations. This Review then provides fundamental insight into the thermal transport in phosphorene by reviewing the role of resonant bonding in driving giant phonon anharmonicity and long-range interactions. In addition, the extrinsic thermal conductivity of phosphorene is reviewed by discussing the effects of strain and substrate, together with phosphorene based heterostructures and nanoribbons. This Review summarizes the progress of thermal transport in phosphorene from both theoretical calculations and experimental measurements, which would be of significance to the design and development of efficient phosphorene based nanoelectronics. © 2018 WILEY-VCH Verlag GmbH & Co.

    In 2005 the Latvian transport consumed 43 PJ, which makes up 23% of the total priMary resources used in the country. On the world scale this latter figure was 17.6% in 2003. On the 1st October of 2005 in Latvia 808.6 thous. of cars, 119.9 thous. of lorries, 10,7 thous. of buses and 27.1 thous. of motorcycles were registred. The annual growth in the number of light motor cars in the last years was 5.5% on the average. In 2005 the Latvian transport consumed 335 thous. tons of petrol and 542 thous. tons of diesel fuel, which makes up 87.4% of the total resources used (in terms of the combustion heat). In the period of 2002-2005 the annual growth of energy resources consumed by transport was 4.87% on the average. According to forecasts, in 2015 the transports of our country will spend 1.64 times more energy resources as compared with 2005. If the transport of 2015 uses hydrogen, then for Latvia 270 thous. tons of this product will be needed. To obtain 270 thous. tons of hydrogen from water using the up-to-date equipment for electrolysis a considerable amount of electric energy is required. Such amount can be produced by generating stations of the total capacity of 1680 MWe(net). This figure is close to that for the total installed capacity of electric energy production already existing in Latvia. (Author)

    Full Text Available Environmental protection has become a common issue in every area, but extremely important for the domains which deal with intensive energy consumption as it is the case of the transportation. Achieving the sustainable cities on the other hand, is also focused on the protection of the environment in order to provide a higher quality of life for the population. Therefore it is considered that by improving the urban transportation planning additional benefits could be provided for both the environment and the sustainable development of the cities. One possibility is to supplement the traditionally land-use plans with the transportrelated zones analysis, where the city is divided in public transport, pedestrian and caroriented zones. Analyzing the transport-related zones of a city is important as it provides additional information in the assessment of the development trend. The process of zoning was conducted for the city of Cluj-Napoca, Romania. In this paper, the outcome of the zoning was analyzed for a more comprehensive review of the urban transport in order to attain a sustainable-oriented approach of the urban area development.

    It is generally accepted that cotransporters transport water in addition to their normal substrates, although the precise mechanism is debated; both active and passive modes of transport have been suggested. The magnitude of the water flux mediated by cotransporters may well be significant: both...... the number of cotransporters per cell and the unit water permeability are high. For example, the Na(+)-glutamate cotransporter (EAAT1) has a unit water permeability one tenth of that of aquaporin (AQP) 1. Cotransporters are widely distributed in the brain and participate in several vital functions: inorganic......(+)-lactate cotransporters. We have previously determined water transport capacities for these cotransporters in model systems (Xenopus oocytes, cell cultures, and in vitro preparations), and will discuss their role in water homeostasis of the astroglial cell under both normo- and pathophysiologal situations. Astroglia...
