  8. Forholdet mellom stat og kommune i styring av norsk utdanningspolitikk 1970 - 2008

    Directory of Open Access Journals (Sweden)

    Øystein Engeland

    2009-06-01

    Full Text Available Denne artikkelen er skrevet ut fra en antakelse om at norsk utdanningsforvaltning etter 1990 illustrerer forsøk på å styrke den statlige forvaltning innen et desentralisert system. Ikke minst er dette tydelig ved at nasjonal styring av utdanning særlig etter århundreskiftet har økt på bekostning av det lokale selvstyret. I forhold til maktfordelingen mellom staten og kommunene er vi nå nærmest tilbake til situasjonen før den politiske desentraliseringsbølgen startet mot slutten av 1970-tallet. Det nasjonale nivået er i ferd med å etablere et styringsgrep på skolesiden som er så omfattende at det mangler sidestykke i moderne tid. Det nye er at dette skjer innen et system hvor inntektssystemet (1986 gir kommunene ansvar for undervisningen, og hvor statens mulighet til å bruke økonomiske styringsmidler er redusert.

  9. Bør man tillate at norske statsborgere benytter seg av surrogati i India?

    2013-11-01

    Full Text Available I Norge er ikke surrogati tillatt, og myndighetene fraråder norske statsborgere å benytte seg av surrogati i utlandet. I denne artikkelen fokuserer vi på kommersiell gestational surrogati og stiller spørsmålet: Bør man tillate at norske statsborgere benytter seg av surrogati i India? De etiske problemstillingene rundt surrogati er mange og sammensatte og blir spesielt utfordrende når tjenesten tilbys i et land med store kulturelle og økonomiske forskjeller både internt og i forhold til Norge. Vi baserer analysen og drøftingen av dette etisk utfordrende spørsmålet på Beauchamps og Childress sin veletablerte metodiske tilnærming innen biomedisinsk etikk. Vi anvender de fire allmennmoralske prinsipper: respekt for autonomi, velgjørenhet, ikke-skade og rettferdighet på sakskomplekset for å synliggjøre spenningene involvert i dette etiske dilemmaet. Med full bevissthet om at det ikke finnes noen lettvinte og omkostningsfrie løsninger på dilemmaer generelt og dette spesielt, konkluderer vi med at interessene til de berørte parter, og spesielt surrogatmødrenes, kan bli bedre ivaretatt om surrogati tillates under omfattende reguleringer. Dersom man velger å gjøre praksisen illegal, vil man også miste mulighetene til å påvirke prosessen og sikre rettighetene til de involverte partene.Nøkkelord: surrogati, Norge–India, utnyttelse, autonomi, regulering av prosessenEnglish summary: Should Norwegian citizens be permitted to use surrogacy in India?Surrogacy is not permitted in Norway, and the government strongly advises against Norwegian citizens travelling abroad to have children through the use of the surrogacy industry. In this article, we focus on commercial gestational surrogacy and debate the question: Should Norwegian citizens be permitted to use surrogacy in India? The ethical concerns regarding surrogacy are complex and are especially challenging when the service is offered in a country with big cultural and economic

    2015-12-01

    Full Text Available The article presents findings from the qualitative study Women in Norwegian theatre, Kvinner i norsk teater (KIT. The researchers have examined the experiences of actresses on the distribution of dramatical roles/parts in Norwegian institutional theatres, in a lifespan perspective. The study is based on 20 qualitative research interviews of a strategic selection of actresses from smaller and larger institutional theatres. We discuss the data with a feministic view and six issues are highlighted in the article: 1. Repertoir, 2. Focus on looks and appearances, 3. Ageism, 4. Role characteristics, 5. Role ambitions/wishes of the actresses, 6. Nobility, 7. Prosesses of change. In the KIT study we find both active and creative innovating actresses and actresses who appear creative but yet more passive. A central discovery is that the success criterion for achieving an enriching professional life as an actress in Norwegian institutional theatres, is to dare “to take the wheel" in order to avoid marginalisation and ageism from the institution.

  12. Mellom risiko og kontroll - en studie av eksplisitte modelleringsformer i norsk grunnskolelærerutdanning

    Directory of Open Access Journals (Sweden)

    Fride Lindstøl

    2017-12-01

    Full Text Available Å være lærerutdanner skiller seg fra andre stillinger innenfor høyere utdanning: Lærerutdanneren underviser både i fagstoff og i hvordan studentene kan lære bort og adaptere fagstoffet i klasserommet. Det at lærerutdanneren underviser i det å undervise, har implikasjoner for hvordan undervisningen planlegges, gjennomføres og analyseres i lærerutdanningen – undervisningens form blir en del av budskapet. Lærerutdannerens arbeid handler derfor om å utforme, velge og sette i spill aktiviteter og oppgaver som kan adaptere fag, forskning, didaktikk og teori til klasserom og profesjonen. Utforming og montasje av de ulike delene eller episodene i et undervisningsforløp kan betegnes som undervisningsforløpets dramaturgi. I denne artikkelen har jeg gjort en dramaturgisk analyse av tre lærerutdanneres undervisning for å identifisere og beskrive hvordan de bruker eksplisitte modelleringsformer, og hva som skjer når de bruker dem. I etterkant av den dramaturgiske analysen har jeg gjort en konvensjonell innholdsanalyse av intervjudata for å undersøke hvordan lærerutdannerne selv forklarer formålet og erfaringer med å bruke eksplisitt modellering i undervisningen. Analyse av tre lærerutdanneres undervisningspraksis sammenfattes i en modelleringsstige som visualiserer hvordan enkelte former for eksplisitte modelleringsformer tilbyr en egen sirkulær dramaturgi. Studien antyder og drøfter også på hvilken måte modelleringsstigen kan fungere som en dramaturgisk modell, som kan brukes som utgangspunkt for lærerutdanneres planlegging, gjennomføring og analyse av egen undervisning. Studien er et bidrag til å utvikle og forske på hvordan eksplisitte modelleringsformer kan brukes for å skape sammenheng mellom praktisk lærerarbeid og teoretisk metarefleksjon i lærerutdannerens undervisning. Innsamling av data er gjort i profesjonsverksted, som kan forklares som en læringsarena hvor lærerutdannere fra ulike fag samarbeider om

    2017-11-01

    Full Text Available Formålet med denne studien var å undersøke elevers oppfatninger av norsklærerens tilbakemeldingspraksis i skriftlig norsk. På bakgrunn av omfattende internasjonal forskning innen feltet ‘Vurdering for læring’ (VfL er det i denne studien utviklet teoridrevne hypoteser som testes ved å analysere et datasett fra to videregående skoler. Hypotesene er at elevene oppfatter lærers tilbakemelding som mer nyttig hvis den 1 retter seg mot målet med opplæringen, 2 gir elevene informasjon via en forklaring eller instruks om hvordan de skal komme nærmere målet og 3 at lærer legger til rette for bruk av tilbakemeldingen. Strukturell likningsmodellering (SEM av resultater fra en spørreundersøkelse blant elever (N = 213 er brukt som metode til å estimere forholdet mellom de fire latente variablene kriterier, forklaring, bruk og nytte (avhengig variabel. SEM er brukt fordi metoden egner seg til å undersøke sammenhenger i komplekse datasett. Funn er at elevene oppfatter at hvis lærer forklarer hvordan de kan forbedre seg, er dette positivt statistisk assosiert med opplevd nytte. Et mer overraskende funn er at lærerens tilrettelegging for bruk av tilbakemeldinger ikke er signifikant assosiert med opplevd nytte. Resultatene blir diskutert i artikkelen.

  15. Hva vet vi (ikke om elevers opplevelser med friluftsliv i norsk skole – en gjennomgang av empiriske studier 1974–2014

    2017-09-01

    Full Text Available Artikkelen presenterer en kunnskapsoversikt basert på en systematisk gjennomgang av empiriske studier om friluftsliv i norsk skole der elevers opplevelser eller stemmer kommer til uttrykk. En slik oversikt er ikke tidligere sammenfattet, selv om det er over 40 år siden ordet friluftsliv kom inn i fagplanformuleringene med Mønsterplanen av 1974. 1974 ble derfor valgt som utgangspunkt for studiens søkeperiode, selv om det kan hevdes at opplæring og undervisning som omfatter aktivitet, læring og opphold i natur allerede fra tidlig 1900-tall har vært en del av norsk skoles oppdrag og virke. For søkeperioden fram til 2014 avdekkes 24 studier som møter inklusjonskriteriene, hvorav 18 er master- og hovedfagsoppgaver. Resultatet forteller at foreliggende empirisk basert kunnskap om elevers opplevelser med friluftsliv i skolen er begrenset og ikke tillater å trekke syntetiserte slutninger. Med den reservasjonen som hovedkonklusjon drøfter artikkelen hvilken kunnskap de inkluderte studier kan gi om friluftsliv i skolen ut fra elevers perspektiv.

    friluftsliv”pedagogy?    Key words: Educational expeditions, Adventure programming, Outdoor educa-tion and Personal growthSammendragArtikkelen handler om friluftsliv brukt pedagogisk med tanke på personlig utvikling. Bakgrunnen er en undring rundt hvorfor temaet personlig utvikling, som står så sentralt i britisk og angloamerikansk pedagogisk friluftslivs-tradisjon, ikke er viet større plass i norsk friluftslivspedagogisk tradisjon. Problemstillingen har vært: Opplever norske bachelorstudenter i friluftsliv at de lærer noe om seg selv og sine egenskaper som ledere under lange ferder i vinterfjellet? Datainnsamlingen har foregått over tre år, i etterkant av tre lange vinterferder med tjuefem 3. års studenter ved Høgskolen i Telemark. Studentene har svart skriftlig på spørsmål knyttet til personlig utvikling. Flere av dem gir uttrykk for en opplevelse av å ha gjort seg erfaringer knyttet til selvbilde/identitet som kan koples til personlige utvikling. Informantene reflekterer bl.a. over opplevelser knyttet til det å mestre og prestere, det å akseptere egne styrker og svakheter, samt det å utvikle troen på seg selv, også i lederrollen. I tillegg reflekteres det over opplevelser av læring knyttet til mellommenneskelig ferdigheter, selvkontroll og kommunikasjon, samt mellommenneskelig forhold knyttet til utøvelsen av lederskap og over omsorgsoppgaver lederskapet innebærer. Opplevelser av læring knyttet til det å ha overblikk, lese situasjoner, gjøre vurderinger og treffe nødvendig tiltak, er også gjenstand for refleksjon. I forlengelsen av dette reflekteres det over viktigheten av å ha fornemme den enkelte, det å oppmuntre, være positiv og gi omsorg. Studien har vist at lange vinterferder, i en norsk tradisjon, har et potensiale til å utløse refleksjoner knyttet til personlig utvikling og ledelse. Kanskje kan denne studien øke bevisstheten rundt de pedagogiske mulighetene som ligger i menneskers møter med andre mennesker i natur?Nøkkelord: Friluftsliv

    2017-03-01

    Full Text Available I 2014 bestemte det norske kronprinsparet seg for å ta barna ut av den offentlige skolen. Tronarvingen, prinsesse Ingrid Alexandra, begynte på Oslo International School, en privatskole med høy egenbetaling der undervisningen foregår på engelsk. Kronprinsparets begrunnelse for skolebyttet var at tronarvingen trengte «et grunnleggende nivå for å tenke, snakke og skrive på engelsk». Artikkelen tar utgangspunkt i en gruppe lærerstudenters fortolkning av kronprinsparets skolevalg og foretar en pedagogisk historisk lesning av valget. Artikkelen gjør bruk av innsikter fra nyere transnasjonale studier i pedagogisk historie og foreslår at fortolkningen av kronprinsparets skolevalg representerer et kritisk punkt i den norske kulturelle selvforståelsen. Lesningen av kronprinsparets skolevalg identifiserer kronprinsparet som den globaliserte norske elitens skolepolitiske avantgarde. Artikkelen konkluderer med at kongefamilien igjen kan synes å gripe den norske tidsånden. Denne gangen i en bevegelse mot et samfunn der det er forskjell på folk.

    Full Text Available The prevalence of sexual offences and abuse within a Norwegian youth population. The aim of this cross-sectional school-based study is to present and discuss the prevalence of sexual abuse within a Norwegian population of young people at the age of 18. Contrary to some earlier Norwegian studies the response rate is fairly high and sexually abuse is more clearly defined. The results are compared with an earlier Norwegian study. A clear gendered pattern can be seen in the data: about a quarter of the young correspondents have experienced sexual offenses, among them 77 percent are girls while 90 per cent of the offenders are males. The same pattern appears in other Nordic studies. Most of the reported sexual offenses towards girls take place when they are in their early teens and the offender is usually a boy some years older, in his teens or early twenties. A sexually offended girl reports more often the use of force or physical violence during the event than an offended boy does. The family is an arena with relatively fewer reported cases of sexually abuse or offences in this study than those of earlier research. We cannot say if this implies a decrease of sexual abuse within the family in Norway but international studies indicate such a tendency in some western countries. To be able to see how the picture of sexual abuse develops in society across time, for instance in a youth population, well prepared prevalence studies should be done within regular time-intervals

    Energieffektivisering i bygninger regnes som et av de mest kostnadseffektive tiltakene for å redusere forbruk av energi, samt bidra til reduksjon i klimagassutslipp. I følge rapporter fra blant annet Lavenergiutvalget (2009) og Klimakur 2020 (2010), vil det være mulig å frigjøre rundt 10 TWh elektrisitet fra norske bygninger i løpet av de neste ti årene. Denne masteroppgaven tar for seg følgene av en tilsvarende etterspørselsreduksjon i det norske kraftsystemet. Norge har et kraftsystem med n...

  12. Lærer- og elevmangfold i det livstolkingsplurale norske klasserommet – utfordringer og muligheter for lærerutdanningen

    Full Text Available Med denne artikkelen ønsker jeg å gi et bidrag til diskusjonen om hvordan lærerutdanningen kan møte utfordringene fra et økt kulturelt mangfold i samfunnet. Siden mitt forsknings- og interessefelt er knyttet til mangfoldet på feltet livstolking, er artikkelens forskningsspørsmål og overordnede problemstilling: Hvordan kan lærerutdanningen møte de utfordringer og muligheter som det livstolkingsplurale norske klasserommet representerer? Delspørsmål jeg utforsker for å svare på dette, er: Hvordan kommer en livstolkingsplural virkelighet til uttrykk i grunnskolens og lærerutdanningens religions- og livssynsfag? Og: Hvordan kan lærerstudenters medvirkning i forskning bidra til å øke deres forståelse for de kravene det livstolkingsplurale norske klasserommet stiller til sine lærere? De empiriske prosjektene som inngår i arbeidet med å besvare forskningsspørsmålene, er utført i norsk offentlig grunnskole og allmenlærerutdanning. Det er naturlig å holde disse prosjektene sammen fordi all norsk lærerutdanning kvalifiserer sine studenter til å arbeide i grunnskolen. Ved å se på hvordan en livstolkingsplural virkelighet kommer til uttrykk i grunnskolens religions- og livssynsfag, vil en følgelig kunne si noe om hvordan deler av den skolehverdagen som norsk lærerutdanning kvalifiserer sine studenter for, ser ut. Dessuten vil en, ved å utforske hvordan en livstolkingsplural virkelighet kommer til uttrykk i lærerutdanningen, kunne si noe om hvordan utdanningen forventes å forberede sine studenter for denne yrkesutfordringen.

    Over the past few years there has been an increase in the amount of consumers that choose to drive an electric car in their everyday lives. Economic and psychological models dominate large segments of research associated with this topic and these models are based on whether or not the choice of driving an electric car is individual. Thus, these models do not take into account social and contextual factors. In this thesis I wish to investigate how the social aspect can affect whether or not a ...

  19. Hva kan norsk skole lære av PISA-vinneren Finland?

    Directory of Open Access Journals (Sweden)

    Svein Østerud

    2016-05-01

    Full Text Available During the last two decades, we have seen an increasing globalization of the education sector, in particular expressed through the implementation of international tests organized by OECD. The use of international tests as a policy tool has been legitimized within international educational development for the purpose of measuring education quality. The normative power of high-stakes standardized testing can be understood as a global testing culture, particularly associated with the three-yearly Student Assessment (PISA in reading, mathematics and science. The testing culture permeates all aspects of school life, creating an atmosphere of competition not only between schools, but also between countries. At the top of the ranking lists of the participating countries we find Finland; their students do slightly better than the students in Singapore and Canada. Paradoxically enough, the Finnish people busy themselves less with the PISA Assessments than people in many other countries, and have kept OECD's New Public Management-oriented reform proposals at a distance. The Finns have always stuck to their locally based school: the authorities have given the highly educated teachers confidence and professional autonomy. There is no doubt that we can learn from the Finnish school system, but not by imitating it. The success of the Finnish school is due to a complex interaction of several factors. Only to the extent that we acknowledge this, can we draw inspiration and guidance from Finnish education for our own school development.

The project started in 1996 by identifying the 61,300 present and former workers on the platformson the Norwegian continental shelf. The main contributors to the crew lists were oil companies, contractingcompanies, labour unions, safety training schools, and the national archives of Norway. In 1998 a selfadministeredquestionnaire was distributed by mail to the 57,000 workers alive and living in Norway. Thequestionnaire included questions on offshore job history, other occupations, leisure activities, and life-stylefactors such as smoking, alcohol consumption and nutrition.The study design of the project is a prospective cohort study, where cancer incidence and mortalityamong the exposed (the offshore workers will be compared with the non-exposed (the general population.Factors known to cause cancer and other diseases in other industries are probably present in the offshorework environment. The offshore workers may also be exposed to harmful agents more or less specific forthe work on the platforms, such as crude oil, gas, and drilling mud. Intense work periods and long leaveperiods, a diet rich in fat and calories, cheap tobacco, a ban on alcohol consumption on the platform, andworry about helicopter flights and platform safety are also factors that may influence the workers' health.The overall response rate was 62%. The collected material will constitute a basis for research in thecoming decades. With regular intervals the cohort will be linked to the cancer database in the CancerRegistry and the Cause of Death Registry at Statistics Norway.Because they are a highly selected group, the offshore workers as a whole will probably be as healthy asthe general population, yet excesses in cancer incidence and certain causes of death among the most exposedworkers (i.e., maintenance workers, drilling personnel, welders, painters and cleaners are expected.

    Claes, Dag Harald

    1997-12-31

    This report is the first study in the research project `` Norwegian gas policy - external change and national adaptation``. The project is financed through Norges forskningsraad`s research program ``Petropol``. The main aim of the project is to understand the market, political and institutional changes in the European gas market as well as what implications they may have for the political and institutional design of the Norwegian gas sector. In this report an approach model is developed for studying the connection between changes in the European gas market and the Norwegian petroleum policy which will be central in several of the later works in the project. The report gives a historic account of Norwegian gas export policy as well, a field where altered frame conditions have given the authorities political and institutional challenges. The main focus in the report is however, connected to the empirical explanation of the connection between changed external environments and alterations in the Norwegian gas export policy. The question the study tries to answer is: To what extent and how the Norwegian gas export policy is affected by alterations in the European gas market and the EU policy towards this market. In the centre of the study of the gas export policy is the element of governmental control. The governmental control assumes ability to formulate national aims as well as the ability to produce laws and regulations which reflects the goals and counts on that the aims are reached in addition to that the authorities either implement the policies themselves or if this is left to other parties, have ability to survey and sanction these parties should they break the guidelines or oppose the national political aims. The report shows how these aspects are affected by changes in the environments surrounding the Norwegian gas export. 6 figs., 1 tab., 45 refs

    On behalf of Enova SF, Prognosesenteret AS and Entelligens AS carried out a potential and barrier study of energy efficiency of the Norwegian housing stock. The study made use of newer and known studies of the Norwegian housing stock, known and documented barriers to energy efficiency, and new and extensive studies of several topics which have only been partially or never explored before. Through unique analysis and a case-based approach, it revealed a real energy efficiency potential in Norwegian homes with known technology and revealed representativeness, relevance, strength and extent of the barriers that prevent that one can realize most of the technical energy efficiency potential in the Norwegian housing stock.

  7. ”I sangen møtes vi på felles grunn.” Om sang og sangbøker i norsk skole.

    Directory of Open Access Journals (Sweden)

    Ragnhild Elisabeth Lund

    2010-12-01

    Full Text Available Sangfaget har en lang og sterk tradisjon i den norske skolestua og sangboka har vært et sentralt læremiddel i mer enn 150 år. Formålet med denne artikkelen er å belyse de mange og ulike begrunnelser som er blitt knyttet til faget opp gjennom tidene og å vise hvilket innhold sangbøkene har søkt å formidle. Presentasjonen av sangfagets begrunnelser er basert på en undersøkelse av skolehistoriske tekster og læreplaner fra tidlig på 1800-tallet fram til vår tid. Jeg har også sett på forordene og forfatternes vektlegging av sangrepertoar og annet sang- og musikkfaglig innhold i de mest toneangivende sangbøkene fra samme periode. For å finne ut hvilke sanger elevene er blitt tilbudt og hvilke verdier sangene formidler, har jeg kartlagt repertoarvalget i tolv sangbokverk fra 1850 (Behrens’ Skolesangbog til 2008 (Amsrud & Bjørnstads Sang i Norge. Artikkelen viser at begrunnelsene for sangfaget favner vidt og at både de og innholdet i sangbøkene har endret seg i takt med utviklingen i utdanningssystemet og i samfunnet forøvrig. Videreformidling av sentrale sanger i norsk kulturarv har selvsagt stått sentralt. Men sangfaget har også befattet seg med opplæring i musikkteori, notelære og stemmepleie, og det har hatt som oppgave å utvikle kvalitetsbevissthet, samhold og fellesskap i tillegg til å bidra til læring og trivsel i andre fag. Når det gjelder repertoarvalg, har utviklingen gått fra en hovedvekt på sanger med et religiøst og oppdragende innhold via nasjonale sanger til en stadig økende andel ”blott-til-lyst-sanger” og sanger fra populærmusikkens område. Til tross for at repertoarvalget har endret seg, er det mange sanger som går igjen gjennom hele perioden. Med referanse til en definisjon av kanon som ”stabile forekomster” identifiserer artikkelen 34 sanger som kan sies å utgjøre en del av ”den norske sangskatten”.

Analysene var basert på 48 lungekrefttilfeller, og man fant atrisikoen var høyest i den gruppen som hadde lengst ansettelse i roste-, smelte- og elektrolyseavdelingene.Tilsvarende funn var tidligere gjort blant nikkelarbeidere i andre land, og undersøkelsen vakte oppsikt fordiforhøyet risiko også ble funnet blant ansatte i elektrolysen. Senere analyser med spesifikke eksponeringsdatahar vist at kreftfaren er nært knyttet til eksponering for vannløselige nikkelformer. Nye data er nå blitt samletinn i forbindelse med en pasient-kontroll-undersøkelse basert på 213 tilfeller av lungekreft og 525 kontrollpersoner.På bakgrunn av opplysningene er relativ risiko regnet ut ved hjelp av regresjonsmodeller derfølgende faktorer var inkludert: total varighet av ansettelse ved bedriften, eller varighet av ansettelse i ulikeavdelinger, tidspunkt for førsteansettelse og røykevaner. Resultatene fra pasient-kontroll-analysen bekreftetfunnene fra 1973 når disse ble regnet om til relativ risiko, og tydet på at konklusjonene fra den gang varvalide selv om analysene var basert på færre arbeidstakere, kortere observasjonstid, en forenklet inndelingav arbeidstakerene i henhold til deres avdelingshistorikk, og manglende opplysninger om røykevanene.Grimsrud TK. Lung cancer among Norwegian nickel-refinery workers: Reappraisial ofa classical study. Nor J Epidemiol 2001; 11 (2: 171-176.  ENGLISH SUMMARYIn 1973, increased risk of cancer of the lung and nasal cavities was demonstrated among Norwegian nickelworkers in a study from The Cancer Registry of Norway (Kreftregisteret.

    Full Text Available Artikkelen undersøker hva slags forståelse lærerutdannere og lærerstudenter har av estetiske arbeidsformer i undervisningen i lærerutdanningene. Studien er en kvalitativ intervjuundersøkelse blant lærerutdannere og lærerstudenter ved en norsk lærerutdanningsinstitusjon. I lys av danningsteoretisk og didaktisk teori, finner studien at lærerutdannere og lærerstudenters forståelse av estetiske arbeidsformer i undervisningen er kjennetegnet av «frihet» som fravær av tvang og fasit i arbeid med lærestoffet, «fantasi» som bruk av forestillingsevnen slik at kunnskapen blir personlig, og «utfoldelse» som sosialisering inn i et fellesskap gjennom tilbakemeldinger på egen atferd. Til sammen kan informantenes forståelse av de tre aspektene sies å fremheve viktigheten av å utvikle de lærendes autonomi. Artikkelen gir et bidrag til undervisningspraksis i lærerutdanningene, gjennom å gi eksempler på hva estetiske arbeidsformer kan være i en slik sammenheng. Avslutningsvis drøftes funnene opp mot samtidige politiske begrunnelser for bruk av estetiske arbeidsformer i utdanningene.

    AVS is a new digital audio-video coding standard established by China. AVS will be used in digital TV broadcasting and next general optical disk. AVS adopted many digital audio-video coding techniques developed by Chinese company and universities in recent years, it has very low complexity compared to H.264, and AVS will charge very low royalty fee through one-step license including all AVS tools. So AVS is a good and competitive candidate for Chinese DTV and next generation optical disk. In addition, Chinese government has published a plan for satellite TV signal directly to home(DTH) and a telecommunication satellite named as SINO 2 will be launched in 2006. AVS will be also one of the best hopeful candidates of audio-video coding standard on satellite signal transmission.

    Agnete Bueie

    2015-03-01

    Full Text Available Denne artikkelen handler om hvordan elever på ungdomstrinnet forstår og bruker skriftlige lærerkommentarer på heldagsprøvebesvarelser i norsk. Slike kommentarer gis ofte på sluttprodukter. I vurderingsforskning antas tilbakemelding på sluttprodukter å ha begrenset verdi som læring, og med denne studien ønsker jeg å se om en slik generell antakelse gjelder også i en norskfaglig kontekst. Det empiriske materiale består av elevtekster med lærerkommentarer, verbale protokoller og individuelle elevintervju for 18 elever. Verbale protokoller brukes for å studere elevenes forståelse av lærerkommentarene, og intervju brukes for å få dypere innsikt i hvordan elevene bruker kommentarene. Studien viser at elevene har liten bevissthet rundt vurderingskriterier. Men de leser vurderingene og viser i hovedsak adekvat forståelse av kommentarene de får. Når det gjelder oppfølging av kommentarene, gjør elevene det som blir forventet av dem. Noen av elevene må «rette» tekstene sine, mens andre er ikke forventet å gjøre noe med kommentarene. Dette gjør at elevene i liten grad bruker kommentarene videre i skrivearbeidet. Mens enkelte internasjonale studier rapporterer om at studenter i høyere utdanning ikke leser tilbakemeldingene (Hounsell, 1987 eller ikke forstår dem (Lea & Street, 1998, viser mitt materiale at elevene leser og forstår kommentarene, og de gjør det som forventes av dem i oppfølgingen. Ved å legge til rette for at elevene skal bruke kommentarene mer aktivt kan kommentarene få en sterkere formativ funksjon.

Formålet med implementeringsforskning er å redusere gapet mellom forskning og praksis, ved å utvikle og evaluere tiltak som kan sikre at behandlingen som pasientene mottar er kunnskapsbasert, at den er omsorgsfull og av god kvalitet.I denne artikkelen gjør vi rede for hva implementering og implementeringsforskning er. Vi belyser historikken til denne unge vitenskapen, og illustrerer mangfoldet i de faglige tilnærmingene og begrepene som brukes om det å få forskning brukt i praksis. Det finnes en rekke teorier om endring av atferd, både på individnivå og på organisatorisk nivå. Teoriene er imidlertid i liten grad testet empirisk, særlig når det gjelder å endre atferd i helsetjenesten.Systematiske oversikter over metodisk gode studier er den beste kilden til informasjon om effekt av implementeringstiltak. The Cochrane Effective Practice and Organisation of Care Group (EPOC er en viktig kilde for slike oversikter. De systematiske oversiktene som er utarbeidet på dette feltet viser at passive dissemineringstiltak har begrenset effekt, mens mer aktive tiltak kan ha liten til moderat effekt. Det er ofte betydelig variasjon i effekt på tvers av studiene. Det er derfor viktig å få bedre kunnskap om hvilke faktorer som kan forklare slike forskjeller i effekt.Vi gir eksempler på norske implementeringsstudier, og refererer bidrag fra forskere ved Kunnskapssenteret. Implementeringsforskningen kan, hvis den lykkes, sikre pasientene bedre behandling.Flottorp S, Aakhus E. Implementation research: science for improving practice.

    Full Text Available Artikkelen tar utgangspunkt i observasjoner fra et klasserom på ungdomstrinnet der elevene arbeider tverrfaglig i norsk, KRL og samfunnsfag. Temaet er blant annet jødenes situasjon før og under krigen. Læreren er faglig dyktig, erfaren og sterkt engasjert i å formidle overgrepene som ble begått mot jødene, og elevene er velvillige. Likevel er elevenes konklusjon at de i en krigssituasjon med en etisk fordring, ikke ville ha våget å gjøre noe for å hjelpe jødene.      Med utgangspunkt i diskursteori, sosiokulturell teori og nyere kognitiv teori diskuteres disse svarene som ”naturlige” svar i den konteksten som skapes i klasserommet, og gjennom det språket som elevene utfordres i, deres ”mediational means”. Et konkret didaktisk problem er at den historiske fortellingen er borte og erstattet av empatisk innlevelse. Artikkelen avslutter med å hevde at uten en narrativ ramme forsvinner muligheten for etisk erkjennelse gjennom konteksten som skapes, og gjennom materialet som foreligger. Her ligger imidlertid nye didaktiske muligheter for engasjerte lærere, ikke minst gjennom litteraturundervisning.

  7. AV dissociation, an inevitable response.

    Science.gov (United States)

    Wang, Kyuhyun; Benditt, David G

    2011-07-01

    The independent activation of the atria and ventricles, AV dissociation, is a common phenomenon that occurs during a wide variety of electrophysiologic circumstances. The clinical significance of AV dissociation is often misunderstood. This article examines the basis and clinical implications of AV dissociation. AV dissociation is often an obligatory, secondary phenomenon, and should not be construed as the primary disorder; it may be due to either the AV conduction system being completely blocked (3° AV block) or the P wave and the QRS complex being generated from separate sources (usually, the AV junction or ventricle) but occurring close together during the physiologic refractory period of each other. The latter may happen in junctional or ventricular arrhythmias including escape or accelerated rhythm, tachycardia, or premature beats. The crucial clinical point is not the AV dissociation itself, but that an underlying triggering primary disorder is present and should be identified. ©2011, Wiley Periodicals, Inc.

Svevestøvet kan deles inn i størrelsesfraksjoner som PMAmbient particulate matter (PM comprises particles from different combustion processes and a variety of mineral particles. The particles vary widely in size distribution and chemical/physical characteristics. PM is often divided into size fractions with different aerodynamic diameters: PM10 (PM ! 10 mm, PM2.5 (PM ! 2.5 mm and PM0.1 (PM ! 0.1 mm. Recent population studies have found an association between an increase in mortality and morbidity due to lung and/or cardiovascular disease and short-term increases in PM. The relative risk (RR was approximately 1.005 for an increase in 10 mg/m3 PM10, without an observed threshold even at concentrations below 10 mg/m3. Chronic exposure has been investigated to a lesser extent, but longterm exposure to PM2.5 has been found to be associated with an approximately 10-fold greater increase in RR than short-term exposures. Experimental studies with volunteers in chamber and field studies show mild lung or cardiovascular responses at concentrations of ambient particles (PM2.5/PM10: 100-200 mg/m3 that may occur during episodes of air pollution. Animal studies at higher concentrations have shown stronger responses. The experimental studies support the epidemiological evidence for an adverse health effect of PM. Both population- and experimental studies indicate the existence of vulnerable individuals. At low to average ambient concentrations there seems to exist a discrepancy between the results of population- and experimental studies that might be due to the absence of the most vulnerable individuals in the experimental studies. Together with cell culture experiments, human and animal studies indicate the importance of physical and chemical properties of the particles (size, content of metals, organics, endotoxins, etc. for

    Full Text Available In the Norwegian curriculum reform, coined ”Kunnskapsløftet,” reading is introduced as one of five basic skills to be emphasised in all subjects, including science. Due to the presence of science-related information and debate in society, competence in reading scientific texts should be considered an important aspect of scientific literacy. In this article I review literature which indicates that many students find it hard to read scientific texts, many science teachers are not aware of the importance of teaching students to read in science, and reading instruction is not common in school science. I therefore present an examination of the emphasis on reading in the new Norwegian science curriculum. Based on the analysis I conclude that, contrary to the intension in the curriculum reform, reading has not received the necessary emphasis to change this picture.

    1999-07-01

    This report examines how Norwegian petroleum investments may contribute to develop industry and a more even distribution of income in the receiving states. It also examines to what extent such investments may help to improve social development, humane rights, health, the environment and safety. The study concentrates on Norwegian investments in Angola. Offshore petroleum activities are capital-intensive and technologically demanding industry which often becomes an enclave in countries with a weakly developed industrial basis and few skilled workers. The profit from this industry accounts for a very large part of the export earnings and of the earnings of the public sector while at the same time this sector creates relatively few jobs in the local community. Thus, the income from the petroleum industry is not widely distributed. The petroleum sector tends to increase the growth of income during its development period but then causes little further development. This can be remedied by an economic policy that deliberately smoothes differences and by taking macro-economic measures which prevent overheating of the economy and which creates space for development in the private sector in the mainland economy. This is difficult, and few oil-exporting developing countries have succeeded so far. In Angola it is hardly possible under the current circumstances with civil war and the absence of institutions that work. The report emphasises that oil companies can contribute with knowledge transfer to local employees and the local state oil company. They should also help to extract Angola's resources in the most efficient and environmentally friendly way. But the social and economical development is the responsibility of the local authorities. Norwegian authorities may provide technical and economical aid, if desired, but it is stressed that there should be a clear division of roles between the authorities and the oil companies.

The authors have taught Norwegian and Swedish for many years in Teacher Education. We discuss the concept of «literary competence», attitudes to literature and reading, and what challenges teacher’s education face. The study is a result of cooperation between Teacher Education in the Nordic countries (Denmark, Sweden, Norway and Finland, financed by Norplus, in the project «Nabospråk i lærerutdannelsen» (Neighbor languages in Teacher Education. The aim of the project has been to promote Nordic student’s mutual understanding of Nordic languages and culture, reading of literature and teaching abilities. This project has made it possible to see the situation not only in a Norwegian, but also in a Nordic perspective. The study shows that the students, who specialize in teaching Norwegian or Swedish on the lower levels in school, read less books than those who qualify for higher levels. The students are positive to reading books in general, and many of them read a lot for pleasure and relaxation, but mostly crime and international bestsellers. They have less experience from other genres in literature and classic texts, and a more reflecting attitude to reading.

    1997-12-31

    The purpose of the study has been to investigate whether Norwegian low energy residences have a lower energy consumption throughout their existence than residences built according to the present practises. The building life span includes in this context production of the necessary building materials, construction and use of the house and demolition and handling of the demolition materials after the house lifetime is over. 5 versions of the building are analysed: 1) A residence built after the building practise according to the 1987 building regulations. 2) A residence built according to the expected practise using the 1997 regulations. 3) A low energy residence which satisfies the demands of U-Values in the 1997 technical regulations but with solar energy equipment and efficient heat recirculation of the exhaust air. 4) A well insulated, low energy residence aided by advanced solar and low energy systems that has a very low energy consumption when in operation. 5) A residence with alternative materials compared to what is normally used in Norwegian residences. The buildings are row houses built at Hamar. All the materials used are mapped. How a large part of the materials is used as well as what materials dominate the various building parts are investigated. The energy content values in most of the building materials have been determined. The yearly energy consumption for operating all the building versions is calculated and the energy for operating is 5 times higher in residences with the largest energy consumption than in residences with the lowest consumption. The energy reduction for all the technical installations used in the row house in the study is determined. The energy consumption for demolition after the life span and transporting the demolition waste is also considered. Finally an analysis is carried out for investigating how uncertainties in the various phases of the life span of the building versions may influence the obtained results. Both an advanced solar energy residence and a house with more traditional solar energy use have in total a lower energy consumption when both energy content and energy consumption for operation are considered than in a traditionally built house of the same type. Generally most of the buildings both use solar energy and energy conservation measures combined with materials with low energy content. 41 refs., 186 tabs., 42 figs., 5 ills.

    This study deals with the competitive relationship between the Norwegian power agreements in end user markets. As expected we find clear evidence of an exploitation of locked-in customers through expensive standard variable rate agreements. One also find evidence that the extent of this utilization have increased after power providers began to use price discrimination of customers more actively. Vendors say the exploitation of locked-in customers have held out for and utilization is often seen as the biggest problem for the market. In time to come, it is not however given that exploitation of locked-customers, through expensive standard variable rate agreements, will continue to be the biggest problem with the market. Today, 60% of households are connected to the spot price contract, and such a percentage would indicate less use of customers. Electricity suppliers uses hand spot agreements without notification to exploit uncertainty customers have about competitive premiums. Agreements without notification will not be registered in this summary power to the Competition Authority and the agreements are therefore difficult to compare for customers. Today, over half of the spot price agreements without notification, and power providers achieve much greater profit on these agreements than the spot price agreements with notification.(eb)

    The 500 or so participants in the fifth Preparation for Retirement seminar held at the end of March were unfortunately deprived of the planned session on the AVS due to the unavailability of the Director of the Caisse Cantonale Genevoise de Compensation (CCGC). We have since had formal confirmation that because of an extra workload due to important changes in the Swiss tax and social legislation and the implementation this summer of the maternity insurance in Geneva, the CCGC has suspended its participation in preparation for retirement seminars in the international organisations for the time being. Conscious of the necessity of offering a session dedicated to the AVS, it is with pleasure that we can inform you that one of our legal advisers, Mr Lorenz Stampfli, has accepted to lead this session. In order to allow for adequate preparation we have reserved the following date: Wednesday 26 September from 14.00 to 16.00 in the Main Amphitheatre The session will be open to all people already registered and any o...

  9. Kritik av den negativa uppbyggligheten

    DEFF Research Database (Denmark)

    Stjernfelt, Frederik; Thomsen, Søren Ulrik

    Under efterkrigstiden har ett märkligt fenomen fått fäste i kulturen. Ett konstverk, en handling, en utsaga bedöms inte längre efter om de är sköna, goda och sanna, utan efter om de bryter mot regler, gör uppror mot det konventionella eller angriper etablerade tänkesätt. Överskridandet av normer...... och provokationen mot inrotade uppfattningar framställs som viktigare än de positiva resultaten, avståndstagandet viktigare än ställningstagandet. Från att ha varit idéer hos ett fåtal filosofer, konstnärer och bohemer har denna negativism efterhand blivit en ideologi för den breda massan. Den...

    Full Text Available Arvelig hemokromatose fører til jernopphopning i kroppen, men gir sjelden alvorlig helseskade. Nesten alle hemokromatosepasienter i vårt land er homozygote for C282Y-mutasjonen i HFE-genet. Omtrent 7 per 1000 innbyggere har denne genotypen. Alvorlig syke blir bare omkring 5-15% av homozygote menn og nesten ingen kvinner. Likevel er det holdepunkter for at screening for hemokromatose blant friske, yngre menn kan være kostnadseffektivt. Det er relativt lett å påvise om en person er disponert for sykdommen, i god tid før den bryter ut, og forebyggende behandling er billig og effektiv. Imidlertid kan vi ikke forutsi hvilke screeningpositive personer som ubehandlet får alvorlig sykdom. Et kontrollert forsøk med screening bør gjennomføresHereditary hemochromatosis – benefits of screening. Hereditary hemochromatosis leads to iron accumulation in the body; however, serious illness due to hemochromatosis is rare. In Norway, almost all patients with hemochromatosis are homozygous for the C282Ymutation in the HFE-gene, a genotype carried by about 7 per 1000 inhabitants. Serious complications are seen in only about 5-15% of homozygous men and in very few women. Nevertheless, screening young men for hemochromatosis may be cost-effective. Detecting predisposed men is relatively straightforward, and prophylactic treatment is cheap and effective. However, we can not predict, among screen-positive men, the few who untreated will become seriously ill. A controlled screening trial should be conducted.

    Full Text Available Artikkelen presenterer to nyere studier av veiledning i praksisopplæring i allmennlærerutdannelsen. Hovedfunnene drøftes i forhold til noen tidligere nordiske forskningsstudier. Studiene redegjør for intensjoner og realiteter i praksisopplæringen med fokus på mål, innhold og form i praksisveiledningen. Materialet er ramme- og fagplaner og intervjuer og observasjoner ved tre praksisskoler. Veiledningen drøftes i forhold til teori om veiledning. De to studiene som presenteres, konkluderer med at avstanden mellom teoridel og praksisdel i lærerutdannelsen fortsatt eksisterer. Det blir konstatert både fellestrekk og forskjeller mellom skolene når det gjelder graden av individuell veiledning og gruppeveiledning og individuell studentundervisning. Innholdsfokus i veiledningen varierte. Veilederrollen varierte mellom ettergivenhet og pågåenhet. Noen forskningsstudier hevder at øvingslærere praktiserer teknologisk veiledning. Artikkelen argumenterer for at innvielse i undervisningstradisjonen er nødvendig.

    2015-08-01

    Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) absence of cardiac and ECG abnormalities; 4) absence of progression to persistent forms of AV block; 5) efficacy of cardiac pacing therapy. The patients affected by idiopathic AV block have low baseline adenosine plasma level values and show an increased susceptibility to exogenous adenosine. The APL value of the patients with idiopathic AV block is much lower than patients affected by vasovagal syncope who have high adenosine values. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Artikkelen gir et praktisk eksempel på hvordan ulike studentgrupper i forbindelse med bygging av nødbivuakk i vinterfjellet opplevde min situasjonsbestemte ledelse som veileder. Teorigrunnlaget viser til situasjonsbestemte ledelsesmodeller og hva som kjennetegner god veiledning i friluftsliv. Datainnsamlingen bygger på kvantitative data fra et spørreskjema og benyttes til å analysere studentenes opplevelse av veileders ledelse ut i fra rangeringsmetoden Visuell Analog Skala (VAS. Fra samme spørreskjema var det også et åpent spørsmål som benyttes til refleksjon over studentenes opplevelse av sikkerhet i undervisningssituasjonen. Resultatene viser at studentgruppene opplevde klare ledelsesforskjeller gjennom de ulike fasene som ledelsen ble delt opp i, men at ledelsesatferden varierte lite i forhold til gruppenes erfaringsgrunnlag. Resultatene tyder på at jeg som veileder i stor grad har blitt påvirket av mine tidligere erfaringer og den potensielle risikoen som ligger ved aktiviteten. Selv om den situasjonsbestemte ledelsen varierte lite mellom de tre gruppene, viser resultatenes store standardavvik at de ulike smågruppene opplevde at ledelsen varierte. Dette tyder på at jeg som veileder til en viss grad har evnet å benytte situasjonsbestemt ledelse i praksis. På grunn av studentgruppenes relativt like oppfatning av ledelsen i de ulike fasene, viser resultatene også noe av vanskelighetene veileder har i forhold til å gjøre en korrekt vurdering av gruppens evner og erfaring i relasjon til læringssituasjonene som oppstår. Sentralt for ledelsen er likevel at studentgruppene opplevde ledelsen som betryggende, noe som gir studentene et godt grunnlag for senere opplevelser i tilknytning til vinterfriluftsliv og bygging av nødbivuakk.

    AV-1451 is an imaging agent labeled with the positron-emitting radiolabel Fluorine-18. 18F-AV-1451 binds paired helical filament tau (PHF-tau), a pathology related to Alzheimer's disease. In our study of AV-1451 uptake in the brains of cognitively normal subjects, we noted a case of a meningioma with visually significant uptake of AV-1451. We initiated the present retrospective study to further examine cases of meningioma that underwent AV-1451 imaging. We searched the patient records of 650 patients who had undergone AV-1451 at our institution for the keyword "meningioma" to identify potential cases. PET/CT and MRI results were visually reviewed and semi-quantitative analysis of PET was performed. A paired student's t test was run between background and tumor standard uptake values. Fisher's exact test was used to examine the association between AV-1451 uptake and presence of calcifications on CT. We identified 12 cases of meningioma, 58% (7/12) of which demonstrated uptake greater than background using both visual analysis and tumor-to-normal cortex ratios (T/N + 1.90 ± 0.83). The paired student's t test revealed no statistically significant difference between background and tumor standard uptake values (p = 0.09); however, cases with a T/N ratio greater than one showed statistically higher uptake in tumor tissue (p = 0.01). A significant association was noted between AV-1451 uptake and presence of calcifications (p = 0.01). AV-1451 PET imaging should be reviewed concurrently with anatomic imaging to prevent misleading interpretations of PHF-tau distribution due to meningiomas.

    The study was designed to assess outcomes of arteriovenous (AV) accesses after interventional stent-graft deployment in haemodialysis patients. 63 haemodialysis patients with 66 AV fistulas and AV grafts were treated by interventional stent-graft deployment from 2006 to 2012 at our hospital. Data of these patients were retrospectively analysed for location of deployed stent-grafts, occurrence and location of (re-)stenosis and (re-)thrombosis. Complex stenosis was the most frequent indication for stent-graft deployment (45.5%), followed by complications of angioplasty with vessel rupture or dissection (31.8%). A high rate of procedural success was achieved (98.5%). The most frequent location of the deployed stent-graft was the draining vein (66.7%). Stent-graft deployment was more frequent in AV grafts than in AV fistulas. Primary patency was 45.5% at 6 month, 31.3% at 12 month and 19.2% at 24 month. Primary patency was significantly better for AV fistulas than for AV grafts with deployed stent-grafts. Patency of the deployed stent-graft was much better than overall AV access primary patency with deployed stent-graft. Re-stenosis with thrombosis was the most frequent indication for re-intervention. Most frequent location of re-stenosis was the draining vein (37.1%), followed by stenosis at the AV access (29.5%) and the deployed stent-graft (23.5%). Re-stenosis and re-thrombosis remain frequent in AV fistulas and AV grafts in haemodialysis patients despite stent-graft deployment. Re-stenosis of the deployed stent-graft is, only in the minority of the cases, responsible for AV access dysfunction.

    Full Text Available  SAMMENDRAGI perioden 1999-2001 vil det bli gjennomført tre kostholdsundersøkelser som til sammen skal kartlegge konsum avmatvarer med betydning for inntaket av miljøgifter i Norge, fortrinnsvis kadmium, kvikksølv, PCB og dioksiner.Disse giftene finnes hovedsakelig i krabbe, flatfisk, skjell, gjedde og abbor, lever eller nyre fra vilt og viltvoksendesopp. Fordi gjennomsnittskonsumet er lavt, spørres det ikke spesifikt om disse matvarene i landsdekkende kostholdsundersøkelsersom 'Norkost'. Hensikten med studien er å kunne gi en bedre beskrivelse av eksponeringsfordelingeni befolkningen med tanke på miljøgifter. Fordelingen er antakelig skjev, dvs. et stort antall personerventes å ha et lavt inntak og noen få personer ventes å ha et relativt høyt inntak av de undersøkte stoffene. Eventuelleukjente risikogrupper vil kunne avdekkes, og det er av stor interesse å undersøke hvor stor eksponeringen i deutsatte gruppene er.Del A av undersøkelsen er landsdekkende og omfatter en postal frekvensundersøkelse til 10 000 tilfeldig valgtepersoner mellom 18 og 79 år. Del B omfatter en postal frekvensundersøkelse til 6000 tilfeldig valgte personer i sekskommuner, der tre er kystkommuner og tre er innlandskommuner. Kommunene blir valgt ut fra kjennskap til godtilgang på de aktuelle matvarene. Vi antar at der tilgangen på matvarene er god, er konsumet høyere. Del C avundersøkelsen vil omfatte høykonsumenter av aktuelle matvarer, valgt fra del B av undersøkelsen. Dette vil være endybdestudie der analyser av miljøgifter i blod, hår og urin også skal inngå.Undersøkelsen er den første i sitt slag her til lands og vi kjenner ikke til at tilsvarende studier er gjort i andreland. Hensikten med artikkelen er å gi en beskrivelse av undersøkelsen i en tidlig fase av gjennomføringen.Meltzer HM, Bergsten C, Stene LC, Stigum H, Wiborg ML, Lund-Larsen K, Alexander J. Consumption ofcontaminated foods – Description of a dietary survey

    Full Text Available Fridtjof Nansen’s expeditions introduced polar exploration in Norway. And his stories from the North formed our image of the Arctic. For later generations of Norwegian explorers Nansen surely has been a great inspiration. Also within polar science Nansen serves as a hero. The article asks to what extent Nansen shared the general political view on Norwegian polar imperialism in the interwar period. That reminds us simultaneously that not all of today's political polar ambitions necessarily are in accordance with Nansen's vision for Arctic research.

In this work, the use of electricity credited with zero greenhouse gas emissions. The work in Climate Cure has been divided by sectors and industry groups in society. The Norwegian Public Roads Administration was responsible for all transportation work, Climate and Pollution Agency has also been responsible for industry, waste and agriculture, the NPD petroleum and NVE has been responsible for the district heating sector and energy use in residential and commercial buildings. It follows that industrial buildings are not included in this sector report, but is taken care of in Climate and Pollution Agency sector report for industry. Dwellings and commercial buildings outside the industry currently accounts for approximately 33% of Norwegian energy and a CO{sub 2} emissions of around 3% of the total Norwegian greenhouse gas emissions. The dwellings were energy consumption 45 TWh in 2007 and 29 TWh in commercial buildings except industrial buildings. Growth in energy consumption in these two building categories were respectively 9% and 23% since 1990, but growth has leveled off in the latter half of the period. In this study of greenhouse gas reduction measures for buildings in Norway are analyzed measures to reduce use of fossil energy in the operational phase of buildings. Life-cycle analysis for buildings with construction and demolition is therefore not considered. This as a result of sectoral division of tasks in Climate Cure and challenges of imports of construction materials to Norway. The use of fossil energy, fuel oil, kerosene and natural gas for heating buildings accounting for emissions. Today, fossil fuels make 7% of energy use in buildings. This can be reduced either by converting away from fossil fuels by adding to for example heat pump or biomass. Alternatively, you can also invest in energy efficiency buildings, but since the buildings will still have some heating needs, this alone does not eliminating fossil energy use altogether. A challenge for the building's long life, making that measures implemented today, the effect is far ahead. It is therefore important to do the right action now so that the 'error' path ahead is avoided. For example, you should switch to the best windows the day you replace the windows as these will be in the building 30 years ahead, or even longer. (AG)

  12. Additional costs for Norwegian power companies from the OED-proposed implementation of the Electricity Directive II; Merkostnader for norske kraftselskaper ved OEDs forslag til implementering av Eldirektiv II

    The cost-related consequences for Norwegian vertically integrated power companies caused by the proposed implementation of Electricity Directive II by OED (Norwegian Oil and Energy Department) are considered. Electricity Directive II demands a company and functional division between the network activities and the activities exposed to competition. The OED proposition aims at lowering the limit for which network companies are included by the new demands, from 100.000 to either 20.000 or 10.000 network clients. Moreover, they propose measures that ensure the network companies' independence, and these exceed by far the minimum requirements of Electricity Directive II. The additional costs may be significant in some aspects. Especially the requirement of an independent management in parent- and subsidiary company will lead to added costs of about Nok 320 million for the Norwegian power business. Further, a split-up management structure may be poorly compatible with the mind set behind the corporate model, something which potentially can lead to bad investments or a weaker utilization of potential cost synergies. The motive for proposing stricter demands on Norwegian power business is among other to limit cross-subsidies so that the competition in the market is reinforced. In light of substantial, quantified additional costs and other negative effects, the proposition's effect on the competition should be investigated further, including alternative measures that may be more cost-effective and/or more accurate (ml)

    From the preface: The Norwegian Global Change (GC) Committee is appointed by the Research Council and works to strengthen the association of Norwegian researchers and research to the international GC programs and IIASA (International Institute for Applied Systems Analysis). As part of this effort, the Committee wanted a survey of Norwegian research activities linked to these programs. CICERO was engaged to carry out survey work in dialogue with the Research and GC Committee. The results of the survey are presented in this report. The GC programs are: World Climate Research Programme (WCRP), International geosphere-biosphere program (IGBP), International program of biodiversity science (DIVERSITAS), International Human Dimension Programme Wed Global Environmental Change (IHDP). In addition to IIASA. The results of the survey will be, and is, used as a basis for further activities of the Committee in terms of incentives that can increase the internationalization of Norwegian research. Furthermore, it help to ensure good coupling to these programs in their transition to a common platform in the international Future Earth Initiative (http://www.icsu.org/future-earth).(eb)

    Full Text Available Migranter som fortsetter å oppholde seg i et land etter avslag på søknad om opphold, eller som unnlater å søke om oppholdstillatelse, utfordrer det juridiske rammeverket for nasjonalstater og statsborgerskap. I denne artikkelen diskuteres livssituasjonen til migranter uten lovlig opphold opp mot normativ kosmopolitisk teori om universelle rettigheter. Dette er belyst i internasjonal litteratur, men i mindre grad innenfor en norsk kontekst. Vi tar i denne artikkelen for oss tre empiriske eksempler: tilværelsen i såkalte ventemottak, tilværelsen utenfor ventemottakene og tilværelsen for barn uten lovlig opphold. Gjennom eksemplene diskuterer vi rettighetsspørsmål i migrantenes liv. Vi viser hvordan menneskerettighetene ikke er tilstrekkelige for å ivareta migrantenes velvære, og hvordan rettigheter migrantene faktisk har, ikke fremstår som reelle fordi det oppleves som risikabelt å benytte seg av dem. Artikkelen setter normativ kosmopolitisk teori i perspektiv ved å diskutere den konkrete situasjonen til migrantene, og spør til slutt hva som kan være konsekvensene av at rettigheter blir ulikt fordelt?Nøkkelord: rettferdighet, rettigheter, migrasjon, ulovlig opphold, kosmopolitismeEnglish summary: Without legal residency = no rights?

    Climent, A M; Guillem, M S; Zhang, Y; Millet, J; Mazgalev, T N

    2011-04-01

    Dual atrioventricular (AV) nodal pathway physiology is described as two different wave fronts that propagate from the atria to the His bundle: one with a longer effective refractory period [fast pathway (FP)] and a second with a shorter effective refractory period [slow pathway (SP)]. By using His electrogram alternance, we have developed a mathematical model of AV conduction that incorporates dual AV nodal pathway physiology. Experiments were performed on five rabbit atrial-AV nodal preparations to develop and test the presented model. His electrogram alternances from the inferior margin of the His bundle were used to identify fast and slow wave front propagations. The ability to predict AV conduction time and the interaction between FP and SP wave fronts have been analyzed during regular and irregular atrial rhythms (e.g., atrial fibrillation). In addition, the role of dual AV nodal pathway wave fronts in the generation of Wenckebach periodicities has been illustrated. Finally, AV node ablative modifications have been evaluated. The model accurately reproduced interactions between FP and SP during regular and irregular atrial pacing protocols. In all experiments, specificity and sensitivity higher than 85% were obtained in the prediction of the pathway responsible for conduction. It has been shown that, during atrial fibrillation, the SP ablation significantly increased the mean HH interval (204 ± 39 vs. 274 ± 50 ms, P AV node mechanisms and should be considered as a step forward in the studies of AV nodal conduction.

    The precise mechanism(s) governing the phenomenon of AV nodal Wenckebach periodicity is not fully elucidated. Currently 2 hypotheses, the decremental conduction and the Rosenbluethian step-delay, are most frequently used. We have provided new evidence that, in addition, dual pathway (DPW) electrophysiology is directly involved in the manifestation of AV nodal Wenckebach phenomenon. AV nodal cellular action potentials (APs) were recorded from 6 rabbit AV node preparations during standard A1A2 and incremental pacing protocols. His electrogram alternans, a validated index of DPW electrophysiology, was used to monitor fast (FP) and slow (SP) pathway conduction. The data were collected in intact AV nodes, as well as after SP ablation. In all studied hearts the Wenckebach cycle started with FP propagation, followed by transition to SP until its ultimate block. During this process complex cellular APs were observed, with decremental foot formations reflecting the fading FP and second depolarizations produced by the SP. In addition, the AV node cells exhibited a progressive loss in maximal diastolic membrane potential (MDP) due to incomplete repolarization. The pause created with the blocked Wenckebach beat was associated with restoration of MDP and reinitiation of the conduction cycle via the FP wavefront. DPW electrophysiology is dynamically involved in the development of AV nodal Wenckebach periodicity. In the intact AV node, the cycle starts with FP that is progressively weakened and then replaced by SP propagation, until block occurs. AV nodal SP modification did not eliminate Wenckebach periodicity but strongly affected its paradigm. © 2011 Wiley Periodicals, Inc.

  4. Pollen transmission of asparagus virus 2 (AV-2) may facilitate mixed infection by two AV-2 isolates in asparagus plants.

    Asparagus virus 2 (AV-2) is a member of the genus Ilarvirus and thought to induce the asparagus decline syndrome. AV-2 is known to be transmitted by seed, and the possibility of pollen transmission was proposed 25 years ago but not verified. In AV-2 sequence analyses, we have unexpectedly found mixed infection by two distinct AV-2 isolates in two asparagus plants. Because mixed infections by two related viruses are normally prevented by cross protection, we suspected that pollen transmission of AV-2 is involved in mixed infection. Immunohistochemical analyses and in situ hybridization using AV-2-infected tobacco plants revealed that AV-2 was localized in the meristem and associated with pollen grains. To experimentally produce a mixed infection via pollen transmission, two Nicotiana benthamiana plants that were infected with each of two AV-2 isolates were crossed. Derived cleaved-amplified polymorphic sequence analysis identified each AV-2 isolate in the progeny seedlings, suggesting that pollen transmission could indeed result in a mixed infection, at least in N. benthamiana.

    Full Text Available BACKGROUND: Helicobacter pylori is the etiologic agent of common gastritis and a risk factor for gastric cancer. It is also one of the richest sources of Type II restriction-modification (R-M systems in microorganisms. PRINCIPAL FINDINGS: We have cloned, expressed and purified a new restriction endonuclease HpyAV from H. pylori strain 26695. We determined the HpyAV DNA recognition sequence and cleavage site as CCTTC 6/5. In addition, we found that HpyAV has a unique metal ion requirement: its cleavage activity is higher with transition metal ions than in Mg(++. The special metal ion requirement of HpyAV can be attributed to the presence of a HNH catalytic site similar to ColE9 nuclease instead of the canonical PD-X-D/EXK catalytic site found in many other REases. Site-directed mutagenesis was carried out to verify the catalytic residues of HpyAV. Mutation of the conserved metal-binding Asn311 and His320 to alanine eliminated cleavage activity. HpyAV variant H295A displayed approximately 1% of wt activity. CONCLUSIONS/SIGNIFICANCE: Some HNH-type endonucleases have unique metal ion cofactor requirement for optimal activities. Homology modeling and site-directed mutagenesis confirmed that HpyAV is a member of the HNH nuclease family. The identification of catalytic residues in HpyAV paved the way for further engineering of the metal binding site. A survey of sequenced microbial genomes uncovered 10 putative R-M systems that show high sequence similarity to the HpyAV system, suggesting lateral transfer of a prototypic HpyAV-like R-M system among these microorganisms.

    Full Text Available Artikkelen er skriven på bakgrunn av problematikk kring utvikling av ein forskingsbasert didaktikk for tekstilundervisninga på grunnstudiet ved Institutt for folkekultur, Høgskolen i Telemark. Delar av forskingsprosjektet tek difor utgangspunkt i eksisterande undervisnings­verksemd ved dette studiet. Spørsmåla som det er søkt å få svar på her, er: Kva dialog og læri­ng er framtredande ved kopiering av ein tradisjonell tekstilgjenstand? og: Korleis har denne arbeidsmåten ein plass i ein forskingsbasert didaktikk? Kopiprosessen skjedde i ein avgrensa oppgåveperiode, utført med to studentgrupper i 2008/2009. Intervju var valt som me­to­de saman med analyse av innhald i oppgåverapportar som var skrivne samtidig med kopiverksemda. I samband med utvikling av ein forskingsbasert didaktikk der kopiverksemd inngår, er drøftingane førte på grunnlag av sosiokulturell og sløydpedagogisk teori, saman med teori i møte med folkekunst. Kopiprosessen er relatert til ein verksemdsmodell for sløydfaget. Resultata er drøfta i høve til mål for oppgåva og gjeldande fagplan. Kopiering som læringsmetode har ein plass i ein forskingsbasert didaktikk når verksemda fører til erkjenning og integrert forståing, ikkje som rekonstruksjon av tradisjonar. Målet for ein forsk­ings­­basert didaktikk er horisontsamansmelting som følgje av hermeneutiske samtaler som gjeld samspel, spatialitet, spelereglar og spelerom i tradisjonen.

    A 72-year-old man with limited cutaneous systemic scleroderma was hospitalized for two episodes of witnessed syncope. The baseline 12-lead electrocardiogram was normal but on telemetry there were numerous episodes of paroxysmal AV block with asystolic periods of up to 7.5 s duration. Analysis of the rhythm strips revealed phase 4 intra-His bundle block characterized by critical P-P intervals that triggered the AV block, and a narrow range of junctional escape to subsequent P wave intervals that were required to release the AV block. A dual chamber pacemaker was implanted. Copyright © 2013 Elsevier Inc. All rights reserved.

    A 60-year-old man presented with recurrent abdominal pain and weight loss for 6 months. Abdominal imaging showed a large vascular lesion in the head and neck of pancreas suggestive of arteriovenous malformation (AV malformation). Endoscopic ultrasound was done which showed features of AV malformation with no evidence of pancreatic malignancy. Surgery was planned for definitive treatment of malformation. Digital subtraction angiography with angioembolization was done prior to surgery to reduce vascularity of the lesion. He recovered after a pylorus preserving pancreaticoduodenectomy. Histopathology of the resected specimen confirmed the pancreatic AV malformation. There has been no recurrence at 2 years of follow-up.

    In connection with the new North Sea Agreement in 1995, Norway may propose that the addition of certain environmentally hazardous chemicals should be reduced. Norway may propose 5-10 substances or groups of substances. This report lists available information about 28 contaminants as a basis for prioritizing. The relevant data shown are physical and chemical properties, quantities produced, emissions, toxicity, decomposition and bioaccumulation. The report also suggests a rough priority. 36 refs., 3 tabs.

  9. The role of AV and VV optimization for CRT

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Cardiac resynchronization therapy is an effective therapy for patients with left ventricular systolic dysfunction and a ventricular conduction delay; however, approximately 30% of patients do not experience significant clinical improvement with this treatment. Modern devices allow individualized programming of the AV delay and VV offset, which offer the possibility of improving clinical response rates with optimized programming. AV and VV delay optimization techniques have included echocardiography, device-based algorithms, and several other novel noninvasive techniques. While an acute improvement in hemodynamic function has been clearly demonstrated with optimized device settings, long-term clinical benefit is limited. In the majority of cases, an empiric AV delay with simultaneous biventricular or left ventricular pacing is adequate. The value of optimization of these intervals in “non-responders” still requires further investigation.

  10. Brachial artery aneurysms following brachio-cephalic AV fistula ligation.

    Peripheral artery aneurysms proximal to a long-standing arteriovenous (AV) fistula can be a serious complication. It is important to be aware of this and manage it appropriately. Vascular access nurses input all data regarding patients undergoing dialysis access procedures into a securely held database prospectively. This was retrospectively reviewed to identify cases of brachial artery aneurysms over the last 3 years. In Morriston Hospital, around 200 forearm and arm AV fistulas are performed annually for vascular access in renal dialysis patients. Of these, approximately 15 (7.5%) are ligated. Three patients who had developed brachial artery aneurysms following AV fistula ligation were identified. All 3 patients had developed brachial artery aneurysms following ligation of a long-standing brachio-cephalic AV fistula. Two patients presented with pain and a pulsatile mass in the arm, and one presented with pins and needles and discoloration of fingertips. Two were managed with resection of the aneurysm and reconstruction with a reversed long saphenous vein interposition graft, the third simply required ligation of a feeding arterial branch. True aneurysm formation proximal to an AV fistula that has been ligated is a rare complication. There are several reasons for why these aneurysms develop in such patients, the most plausible one being the increase in blood flow and resistance following ligation of the AV fistula. Of note, all the patients in this study were on immunosuppressive therapy following successful renal transplantation. Vigilance by the vascular access team and nephrologists is paramount to identify those patients who may warrant further evaluation and investigation by the vascular surgeon.

  11. Lesing av delvis motstridende tekster i syvende klasse

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available I denne artikkelen ser vi på hvilken type informasjon elever i 7. klasse vektlegger for å konstruere en sammenhengende oppsummering av fire til dels motstridende tekster. Elever møter ofte flere tekster om samme tema – multiple tekster – og vi trenger økt kunnskap om hvordan de leser slike tekster. Elevene leste fire ulike tekster om en sykkelulykke. Tekstene presenterte informasjon som var delvis sammenfallende på tvers av alle tekstene, og delvis motstridende informasjon som innebar at enkelte tekster ga ulike beskrivelser av hendelsesforløpet. Vi testet elevenes ordavkodingsferdigheter, fikk dem til å fylle ut et spørreskjema om lesevaner og vi innhentet elevenes resultater på Nasjonal leseprøve. Etter lesing ba vi elevene gi en oppsummering av sykkelulykken. Elevene gjenga relativt mer sammenfallende informasjon enn motstridende informasjon. Gode resultater på Nasjonal leseprøve ser ut til å ha en sammenheng med elevenes ferdigheter i å konstruere en sammenhengende forståelse av de fire tekstene. Elever som oppga å lese mye på Internett hadde imidlertid fått med mindre av informasjonen som var felles for de fire tekstene i sine oppsummeringer. Vi fant også en negativ sammenheng mellom fritidslesing på Internett og resultatene fra Nasjonal leseprøve. Samlet sett indikerer resultatene at når elevene skal skape sammenheng mellom flere delvis motstridende tekster, så blir sammenfallende informasjon vektlagt mer enn motstridende informasjon. Dessuten ser det ut til at de elevene som bruker mest fritid til å lese på Internett, sliter mer med å sammenfatte innholdet i de fire tekstene enn de andre elevene.

  5. Norwegian Petroleum Policy; Norsk petroleumspolitikk

    Energy Technology Data Exchange (ETDEWEB)

    Froeiland, Ranveig

    1997-12-31

    This presentation discusses the environment, the petroleum fortune and future generations, licence policy, and regional issues. A principal aim for the Norwegian government is to combine the role as a major energy producer with the desire to be a leading country in environmental issues. Norway is now a major oil and gas producer that produces effectively, profitably and more environmentally friendly than other petroleum countries. The MILJOESOK process was started to strengthen the cooperation between Norwegian authorities and the industry in the environmental sector. The emissions of greenhouse gases per unit produced have been reduced. The emissions to sea of oil and chemicals are also being reduced. Another principle aim is that the oil and gas resources should give the highest possible value creation and secure welfare and employment. With the present production level the reserves of oil will last for 15 years and the reserves of gas for 110 years. The state income generated by the petroleum production is expected to peak around the turn of the millennium, then to decline gradually toward 2050. The petroleum fund is established to be a buffer till long into the future. In 2010, the yield from this fund is expected to be twice the amount of oil money used over the state budget today. Compared with the UK, Norway has chosen to exploit the resources in a step by step fashion at a moderate rate. This policy can be seen in the granting of concession. New concessions will be granted at a rate suitable for smoothing out the activity level and strengthening onshore employment. The North Sea, the Norwegian Sea and the Barents Sea are quite different as to mapping and maturity and hence require different concession policies. The new deep-sea fields in the Norwegian Sea offer technological challenges and it is important that offshore activities in this area create opportunities for regional development on land

    Full Text Available  SAMMENDRAGSvalbard er spesielt godt egnet til å vurdere påliteligheten av selvrapportert alkoholkonsum. På grunn av detlave prisnivået for alkohol er ulovlig import eller hjemmeproduksjon av alkohol ukjent på Svalbard. Dessutener samfunnet lite og oversiktlig, slik at det er praktisk mulig å undersøke hele befolkningen. I den aktuellestudien registrerte vi alt salg av alkohol til fastboende nordmenn på Svalbard i oktober og november 1988. Isamme tidsperiode ble alle nordmenn 18 år eller eldre invitert til å ta del i en helseundersøkelse der det inngikkspørsmål om alkoholbruk. Vi fant at selvrapportert alkoholkonsum utgjorde rundt 40% av salgsvolumet.På grunn av de spesielle forhold når det gjelder alkoholomsetning på Svalbard er det grunn til å anta atestimatet i denne studien er mer pålitelig sammenlignet med tilsvarende studier fra andre områder.Høyer G, Nilssen O, Brenn T, Schirmer H. The reliability of self-reported alcohol consumption.The Svalbard study 1988-89. Nor J Epidemiol 1996; 6 (1: 109-113.ENGLISH SUMMARYThe Norwegian island of Spitzbergen, Svalbard offers a unique setting for validation studies on self-reportedalcohol consumption. No counterfeit production or illegal import exists, thus making a complete registrationof all sources of alcohol possible. In this study we recorded sales from all agencies selling alcohol onSvalbard over a two month period in 1988. During the same period all adults living permanently on Svalbardwere invited to take part in a health screening. As part of the screening a self-administered questionnaire onalcohol consumption was introduced to the participants. We found that the self-reported volume accounted forapproximately 40 percent of the sales volume. Because of the unique situation applying to Svalbard, theestimate made in this study is believed to be more reliable compared to other studies using sales volume tovalidate self-reports.

    Full Text Available A whole I frame AVS real-time video encoder is designed and implemented on FPGA platform in this paper. The system uses the structure of the flow calculation, coupled with a dual-port RAM memory between/among the various functional modules. Reusable design and pipeline design are used to optimize various encoding module and to ensure the efficient operation of the pipeline. Through the simulation of ISE software and the verification of Xilinx Vritex-4 pro platform, it can be seen that the highest working frequency can be up to 110 MHz, meeting the requirements of the whole I frame real- time encoding of AVS in CIF resolution.

    2014-02-01

    Full Text Available Denne artikkelen retter fokus mot studenters læring i praksis. Gjennom beskrivelsen av et pilotprosjekt i barnevernet, ønsker vi å synliggjøre hvordan bruken av studenter som medforskere kan bidra til økt kunnskapsutbytte samt en større forståelse av samspillet mellom teori og praksis. Samtidig har feltet sosialt arbeid behov for en modernisering. Denne artikkelen søker å vise at bruk av studenter som medforskere kan bidra til den nevnte modernisering. To spørsmål reises i artikkelen: Hvordan håndterer lærere og studenter utfordringer i forskningsprosessen i prosjekter hvor studenter deltar som medforskere? På hvilken måte kan praksisnær forskning bidra til å kaste lys over studentens læring? Abstract Students as research assistants – a pilot project in child welfare services.This article concerns students’ learning outcomes. Through a description of a pilot project in child welfare services, the aim is to demonstrate how the use of students as research assistants can contribute to increased knowledge outcomes and provide a better understanding of the interaction between theory and practice. At the same time, the field of social work needs a modernization. The article argues that the use of students as research assistants can contribute to the aforementioned modernization. Two issues are raised in the article: How to deal with teachers’ and students’ challenges in the research process in projects where students participate as research assistants? In what way can survivor research shed light on students’ learning outcomes?

    Full Text Available Norges Idrettsforbund og Olympiske og Paralympiske Komité (NIF har en uttalt målsetting om en åpen og inkluderende idrett. Hvordan kommer dette til uttrykk i den praktiske virksomheten? Denne artikkelen, som bygger på data fra en undersøkelse om likestilling og mangfold i den organiserte idretten (NIF, retter søkelyset mot arbeid med inklusjon av ungdom med minoritetsbakgrunn på ulike organisasjonsnivå i NIF: særforbund, idrettskretser og idrettslag. Datamaterialet er kvalitative intervju med representanter fra ulike organisasjonsnivå. Resultatene viser at NIFs overordnede politikk i varierende grad nedfelles i særforbundenes virksomhet, i idrettskretsene og i idrettslagene. Av særforbundene skiller Fotballforbundet og Klatreforbundet seg ut som aktive pådrivere i arbeidet med inkludering. Mange idrettslag oppfattet slike spørsmål som lite aktuelle i sitt rekrutteringsområde. Representanter for lag som hadde erfaring med inkludering og rekruttering av minoritetsungdom, tilkjennega varierte erfaringer og synspunkter.

  10. Torsional changes in surgery for A-V phenomena.

    Science.gov (United States)

    Sharma, P; Halder, M; Prakash, P

    1997-03-01

    The role of torsion in the aetiopathogenesis of A-V phenomena has not been sufficiently emphasized. The success of vertical displacement of horizontal recti in correction of A or V has not been attributed to torsional changes. To evaluate this aspect, 21 cases of A or V phenomena were subjected to monocular recession-resection procedure with vertical shifting. Preoperative and postoperative torsional changes were evaluated on synoptophore (subjective torsion), and confirmed by fundus photography (objective torsion). Intorsion with A phenomenon was seen preoperatively in 5 of 8 cases which increased after surgery and was seen postoperatively in the other 3 cases also. Extorsion was observed in 5 of 13 cases pre operatively in 'V' phenomenon, but the changes in extorsion after surgery were less dramatic than those in intorsion. The oblique overactions were reduced in cases where they were present. Correction of A-V phenomena by torsion induced by vertical shifting of horizontal recti muscles is proposed, highlighting the role of torsion in A-V phenomena.

    Full Text Available Artikkelen tar utgangspunkt i tre observasjoner av en gutt på fire år som bruker iPad på fritiden. Den søker å synliggjøre de strategiene dette barnet velger for å skaffe seg tilgang til ulike medietekster, hvordan han leser og tolker dem, og den undersøker eventuelle spor av kritisk refleksjon hos barnet over disse tekstene. Teoretisk sett hviler den på en forståelse av mediekompetanse som en parallell prosess til utvikling av lese- og skrivekyndighet (literacy, og medieopplevelsene omtales som viktige møter med tekst. Artikkelen undersøker hvordan å lese medietekster kan legge et grunnlag for å utvikle en utvidet tekstkompetanse eller mediekompetanse. Konklusjonen legger vekt på motivasjon og lekenhet som barns primære inngang til medietekstene og som et grunnlag for å utvikle mediekompetanse (media literacy. The article is based on three observations of a four-year-old boy who uses the iPad in his spare time. It demonstrates the strategies that this boy applies to gain access to various media texts, and how he reads and interprets them. It also seeks to examine traces of critical reflection that he may demonstrate in relation to these texts. Theoretically, it rests on an understanding of media literacy as a parallel process to the development of literacy, and it seeks to demonstrate how reading media texts can create an important starting point for the development of media literacy. The Kindergarten practitioner’s role and opportunities to develop children's media literacy within a kindergarten context is a focus towards the end of the article. In conclusion, I argue that motivation and playfulness are important approaches to media texts and create an important foundation for the development of media literacy

    2010-01-01

    Full Text Available På et fotballag i overgangen mellom barne- og ungdomsfotballen er spilletid på fotballbanen under kamp både en knapp ressurs og en kilde til diskusjoner om fordeling. Spørsmålet som er utgangspunkt for denne artikkelen, er hvilke hensyn som bør tas når trener og lagleder skal fordele samlet spilletid på enkeltspillere. Er det viktigst å vinne fotballkampen, eller har det størst betydning å fordele spilletiden mest mulig likt mellom spillerne? Skal det tas hensyn til guttenes evner, motivasjon og preferanser? Er deres familiebakgrunn og personlighet av betydning? Diskusjonen baserer seg på en gjennomgang av ulike politiske rettferdighetsteorier for fordeling av knappe goder.Nøkkelord: rettferdighet, practice, fordelingsrettferdighet, diskursetikk, idrettsetikkEnglish summary: Minutes of justice: Distribution of time during football matches in a boys' teamDuring a football match, time for playing can be considered as a limited good. In this article the point of departure is the redistribution of time in a boys' football team in the transition phase between children and youth football. The questions are how and under which conditions time for playing should be distributed among the players. Is winning the game more important than trying to let every player play for an equal amount of time? Should the boys' talents, motivation, and preferences be considered while distributing time, or are family background and personality of importance? Different theories of political justice for the distribution of limited goods underpin the discussion of how to distribute the minutes of playing time during a football match.http://dx.doi.org/10.5324/eip.v4i1.1737

  15. Artificial vision support system (AVS(2)) for improved prosthetic vision.

    Science.gov (United States)

    Fink, Wolfgang; Tarbell, Mark A

    2014-11-01

    State-of-the-art and upcoming camera-driven, implanted artificial vision systems provide only tens to hundreds of electrodes, affording only limited visual perception for blind subjects. Therefore, real time image processing is crucial to enhance and optimize this limited perception. Since tens or hundreds of pixels/electrodes allow only for a very crude approximation of the typically megapixel optical resolution of the external camera image feed, the preservation and enhancement of contrast differences and transitions, such as edges, are especially important compared to picture details such as object texture. An Artificial Vision Support System (AVS(2)) is devised that displays the captured video stream in a pixelation conforming to the dimension of the epi-retinal implant electrode array. AVS(2), using efficient image processing modules, modifies the captured video stream in real time, enhancing 'present but hidden' objects to overcome inadequacies or extremes in the camera imagery. As a result, visual prosthesis carriers may now be able to discern such objects in their 'field-of-view', thus enabling mobility in environments that would otherwise be too hazardous to navigate. The image processing modules can be engaged repeatedly in a user-defined order, which is a unique capability. AVS(2) is directly applicable to any artificial vision system that is based on an imaging modality (video, infrared, sound, ultrasound, microwave, radar, etc.) as the first step in the stimulation/processing cascade, such as: retinal implants (i.e. epi-retinal, sub-retinal, suprachoroidal), optic nerve implants, cortical implants, electric tongue stimulators, or tactile stimulators.

  20. Minimizing ventricular pacing by a novel atrioventricular (AV) delay hysteresis algorithm in patients with intact or compromised intrinsic AV conduction and different atrial and ventricular lead locations.

    Science.gov (United States)

    Pakarinen, Sami; Toivonen, Lauri

    2013-09-01

    To investigate if an advanced AV search hysteresis (AVSH) algorithm, Ventricular Intrinsic Preference (VIP(™)), reduces the incidence of ventricular pacing (VP) in sinus node dysfunction (SND) with both intact and compromised AV conduction and with intermittent AV block regardless of the lead positions in the right atria and the ventricle. Patients were classified as having intact AV (AVi) conduction if the PR interval was ≤ 210 ms on ECG and 1:1 AV conduction during atrial pacing up to 120 bpm with PR interval ≤ 350 ms. Otherwise the AV conduction was classified as compromised (AVc). Both AVi and AVc patients were randomized to VIP ON or OFF. VIP performed an intrinsic AV conduction search every 30 s for three consecutive atrial cycles with the extension of the sensed and paced AV (SAV/PAV) delays from basic values of 150/200 ms to 300/350 ms. Extended AV intervals were allowed for three cycles when VP occurred before returning to basic AV delays. The primary end-point was %VP at 12 months. Among 389 patients, 30.1% had intact and 69.9% had compromised AV conduction. The mean %VP at 12 months was 9.6% by VIP compared to 51.8% with standard AV settings in patients with AVi (P < 0.0001) and 28.0% versus 78.9% (P < 0.0001) with AVc. With VIP, excessive %VP among most used lead positions was not seen. Conversely, when VIP was off %VP was low only in patients who had leads in the RA septal-RV septal position (23.0%). VIP feature reduces VP both in patients with SND and with intermittent heart block regardless of the lead positions in the right atria and the ventricle.

    Science.gov (United States)

    Wu, N. Eva

    2001-01-01

    UNIPASS is a general-purpose probabilistic computer program consisting of three major modules, including preprocessor, solver and postprocessor. UNIPASS contains a user-friendly Graphical User Interface (GUI), numerous state-of-the-art probabilistic analysis techniques, a large library of statistical distributions and a function module with a large library of support functions that can easily define any complex limit-state function in a scripting FORTRAN-like syntax format. Its inverse probability analysis and sensitivities analysis capabilities make it a powerful design aid in any product cycle. Its precise numerical analysis engine is accurate enough to push the failure probabilities of a design to well below 10 (exp -50). UNIPASS is equipped with advanced artificial intelligence that is designed to handle systems with an essentially unlimited number of random variables with ease and efficiency. Its modular arrangement allows you to tailor an analysis to the desired level of accuracy and efficiency. The depth and comprehensiveness of UNIPASS are built upon the decades of experience and expertise of industry leaders including Boeing Aircraft, NASA and the DoD. Its rich content also makes UNIPASS a valuable instructional tool for random processes and probabilistic mechanics. The topics include: 1) Reliability in AvSP; 2) Role of UNIPASS in AvSP; and 3) Examples. This paper is in viewgraph form.

  12. American AV: Edgar Dale and the Information Age Classroom.

    Science.gov (United States)

    Acland, Charles R

    2017-01-01

    This article demonstrates how the influential scholar Edgar Dale, alongside a generation of educational technologists, helped build an essential place for AV materials and pedagogical methods in the American classroom. It also shows that, for decades, the Payne Fund philanthropy supported multimedia research agendas that shaped ideas about teaching and technology, far beyond involvement in their famed studies on motion pictures and children in the 1930s. With his writings and research programs, Dale advanced concepts of media experience and systematicity, which came to be understood as common sense to the information society. In so doing he was a leading contributor to the discursive and ideological structure of our age of technological and informational abundance.

    2016-04-01

    Full Text Available I utdanningsvitenskapelig litteratur er ulike former for ”literacy” et vedvarende fokus både teoretisk og empirisk. I engelskspråklig naturfagdidaktisk litteratur brukes betegnelsen ”scientific literacy”. Jeg skisserer i denne artikkelen et planleggingsverktøy for undervisning som bygger på en eksplisitt teoretisk modell for deltakelse gjennom språk. Modellen er bindeledd mellom et generalisert kompetansebegrep og planlegging av undervisning ved at den knytter sammen de didaktiske spørsmålene hva, hvem, hvordan og hvorfor med en modell for funksjonell deltakelse. Modellen er spesielt relevant for et allmenndannende ”naturfag for alle”, men favner også et naturfag som fokuserer på utdanning av framtidas naturvitere. Artikkelen retter seg mot naturfag i skolen, men modellen bør kunne anvendes også i andre skolefag. Modellen peker mot et situert og transformativt kompetansebegrep.Nøkkelord: naturfag , kompetanse , diskurs , deltakelse, undervisning og læringAbstractVarious forms of literacy have long been the focus of educational discourses, not the least in science education where the term “scientific literacy” has been an enduring concern for decades. In this article I describe a tool for designing teaching based on a theoretical perspective on participation through language. The model connects a general conception of competence with the planning of teaching. To do so it drowe on the didactical questions of “what, who, how and why”. The model is particularly relevant in a “science for all” perspective but also for the educating of future science specialists. Although school science is the primary focus in this article, the model should be applicable to other school subjects as well. The model opens for a situated and transformative notion of competence.Keywords: scientific literacy, discourse, participation, teaching and learning

    Full Text Available O tornar-se avó assinala um período de transição no ciclo de vida familiar, marcado por transformações psíquicas significativas para os avós, caracterizando a quarta individuação. Este trabalho teve como objetivo investigar a experiência de tornar-se avó e sua importância no processo de individuação. Foi utilizado delineamento de estudo de caso coletivo. Onze avós maternas, com idades entre 49 e 66 anos, cujas filhas tiveram seu primeiro filho, responderam a uma entrevista semi-estruturada. Todas as avós tinham tido seus primeiros netos e a entrevista referia-se a sua experiência como avós desses netos. Os dados mostraram que o ser avó é uma fonte de renovação e renascimento. O estudo propiciou que as participantes refletissem sobre seus diferentes papéis familiares: avó, mãe, neta e filha. Os dados sugerem que tornar-se avó possibilita que antigos conflitos sejam repensados, renovando antigos vínculos e desejos, o que permite que a avó dê mais um passo rumo à sua individuação.

  18. Prevalence of E/A wave fusion and A wave truncation in DDD pacemaker patients with complete AV block under nominal AV intervals.

    2015-01-01

    Optimization of the AV-interval (AVI) in DDD pacemakers improves cardiac hemodynamics and reduces pacemaker syndromes. Manual optimization is typically not performed in clinical routine. In the present study we analyze the prevalence of E/A wave fusion and A wave truncation under resting conditions in 160 patients with complete AV block (AVB) under the pre-programmed AVI. We manually optimized sub-optimal AVI. We analyzed 160 pacemaker patients with complete AVB, both in sinus rhythm (AV-sense; n = 129) and under atrial pacing (AV-pace; n = 31). Using Doppler analyses of the transmitral inflow we classified the nominal AVI as: a) normal, b) too long (E/A wave fusion) or c) too short (A wave truncation). In patients with a sub-optimal AVI, we performed manual optimization according to the recommendations of the American Society of Echocardiography. All AVB patients with atrial pacing exhibited a normal transmitral inflow under the nominal AV-pace intervals (100%). In contrast, 25 AVB patients in sinus rhythm showed E/A wave fusion under the pre-programmed AV-sense intervals (19.4%; 95% confidence interval (CI): 12.6-26.2%). A wave truncations were not observed in any patient. All patients with a complete E/A wave fusion achieved a normal transmitral inflow after AV-sense interval reduction (mean optimized AVI: 79.4 ± 13.6 ms). Given the rate of 19.4% (CI 12.6-26.2%) of patients with a too long nominal AV-sense interval, automatic algorithms may prove useful in improving cardiac hemodynamics, especially in the subgroup of atrially triggered pacemaker patients with AV node diseases.

    The objective of this AVS testing program is to use bench-scale test equipment to produce a vitrified product at maximum waste loading from the specified AZ-101 waste simulant and conduct a TTT analysis using laboratory scale melts to show compliance with the DOE Waste Acceptance Product Specifications for Vitrified High-Level Waste Forms (WAPS). The vitrified product complies with the following WAPS. A borosilicate glass with a waste loading of 60.9-wt% was produced from a slurry feed of AZ101 simulant. Glass durability testing, glass characterization testing, and testing methodology were performed in accordance with the Department of Energy approved Test Plan. The glass has two crystalline phases and good uniformity of composition. The Product Consistency Test on the 6 location-specific samples are at least 1 to 2 orders of magnitude below the mean PCT results for the EA glass. Standard deviations were less than 10% of measured values. The glass transition temperature averaged 658 ± 9 C. A TTT diagram was produced. There was measured cesium loss of about 2%, and compliance with the Universal Treatment Standards

    NASA's Dawn spacecraft arrived at the asteroid 4 Vesta in July 2011 and is now collecting imaging and spectroscopic data during its one-year orbital mission. The maps we present are based on information obtained by the Visible and Infrared Mapping Spectrometer VIR-MS and the multi-color Framing Camera FC. VIR covers the wavelength range between 0.25 to 5.1 µm while FC covers the range 0.4 to 1.0 µm. The VIR instrument has a significant higher spectral resolution than FC but the latter achieves higher spatial resolution data. As part of the geological and mineralogical analysis of the surface, a series of 15 quadrangles have been defined covering the entire surface of Vesta. We report about the mapping results of quadrangle Av-6 (Gegania) and Av-7 (Lucaria). The Gegania quadrangle is dominated by old craters showing no ejecta blankets and rays while several small fresh craters do. The most obvious geologic features are a set of equatorial troughs, a group of three ghost craters of similar diameter (~57 km), an ejecta mantling of the Gegania crater and three smaller craters showing bright and dark ejecta rays. The quadrangle contains two main geologic units: 1) the northern cratered trough terrain and 2) the equatorial ridge and trough terrain. The quadrangle shows moderate variation in Band II center wavelength and Band II depth. FC color ratio variations of some recent craters and their ejecta are linked to the bright and dark material. The bright material is possibly excavated eucritic material while the dark material could be remnants of a CM2 impator(s) or an excavated subsurface layer of endogenic origin. The most prominent geologic features in the Lucaria quadrangle are the 40 km long hill Lucaria Tholus, a set of equatorial troughs, some relatively fresh craters with bright and dark material and mass wasting. The quadrangle contains three main geologic units: 1) the northern cratered trough terrain, 2) the equatorial ridge and trough terrain, and 3) the

    Lars Tore Ødegård

    2015-11-01

    Full Text Available Det er en utbredt oppfatning at det økende prestasjonskravet i toppfotball fører til en svekkelse av moral og fair play-holdninger. Men hvordan tenker toppfotballspillere i forhold til ulike dilemmaer som oppstår på banen, og er det forskjeller mellom toppfotballspillere og spillere på lavere nivå?  For å avklare dette gjennomførte vi en empirisk undersøkelse der vi intervjuet spillere og trener i én toppklubb og én breddeklubb. Vi var interessert i to hovedproblemstillinger:  1 Hva tenker fotballspillere på ulike prestasjonsnivå om etikk og moralske dilemmaer i fotball? 2 Hvilke faktorer påvirker spillerne, direkte og indirekte, i deres vurderinger og handlinger? Resultatene fra undersøkelsen viser at det er store forskjeller mellom de to prestasjonsnivåene. Spillerne på breddenivået føler generelt et større ansvar for å opptre ærlig på banen enn hva som er tilfelle på toppnivået. Vi fant 4 spesifikke faktorer i toppfotballen som bidrar til umoralsk opptreden. For det første opplever spillerne en forventning om at de prioriterer resultat foran fair play. For det andre bidrar tilstedeværelsen av supportere på kamper til en slik prioritering. For det tredje vil handlinger som er i strid med fair play signaliseres som akseptable internt i miljøet, selv om de ofte signaliseres som uakseptable overfor media og omverdenen. For det fjerde kan spillere oppleve det som vanskelig å gå i mot trenerens oppfordringer til en pragmatisk og resultatfokusert opptreden.Nøkkelord: moral, etikk, fair play, footballEnglish summary: How morally do football players think? – an empirical study of moral dilemmas in elite footballIt is a common view that the increasing focus on achievement and success in elite football leads to a weakening of moral and fair play attitudes.

    Atrioventricular (AV) delay optimization improves hemodynamics and clinical parameters in patients treated with cardiac resynchronization therapy and dual-chamber-pacemakers (PM). However, data on optimizing AV delay in patients treated with VDD-PMs are scarce. We, therefore, investigated the acute and chronic effects of AV delay optimization on hemodynamics in patients treated with VDD-PMs due to AV-conduction disturbances. In this prospective, single-center interventional trial, we included 64 patients (38 men, 26 women, median age: 77 (70-82) years) with implanted VDD-PM. AV-delay optimization was performed using a formula based on the surface electrocardiogram (ECG). Hemodynamic parameters (stroke volume (SV), cardiac output (CO), heart rate (HR), and blood pressure (BP)) were measured at baseline and follow-up after 3 months using impedance cardiography. Using an ECG formula for AV-delay optimization, the AV interval was decreased from 180 (180-180) to 75 (75-100) ms. At baseline, AV-delay optimization led to a significant increase of both SV (71.3 ± 15.8 vs. 55.3 ± 12.7 ml, p AV delay vs. nominal AV interval, respectively) and CO (5.1 ± 1.4 vs. 3.9 ± 1.0 l/min, p AV-delay optimization in patients treated with VDD-PMs exhibits immediate beneficial effects on hemodynamic parameters that are sustained for 3 months.

    2015-08-01

    Full Text Available Artikkelen drøfter eit sentralt problemfelt innom litteraturdidaktikken, nemleg tilhøvet mellom litterær lesing som fagleg kompetanse og litterær lesing som oppleving. Problemfeltet er særleg knytt til Louise Rosenblatts arbeid. Ho viser ved hjelp av omgrepa efferent og estetisk lesing korleis det er ei utfordring for litteraturlæraren å utvikle ei litteraturundervisning som i tilstrekkeleg grad tek omsyn til kjensler og røynsler. I ein litteraturteoretisk kontekst er subjektive responsar på litterære tekstar irrelevante, men i ein litteraturdidaktisk kontekst er subjektive responsar høgst relevante. Denne artikkelen bidrar inn i diskusjon-en mellom anna ved å trekkje inn meir empirisk basert litteraturteori som referanseramme. Artikkelen presenterer tre lesarars litterære responsar, og viser korleis kunnskap om individuelle lesarresponsar kan vere utgangspunkt for ei litteraturundervisning som balanserer ei fagleg tilnærming til litteratur opp mot ei meir opplevingsbasert tilnærming.Emneord: Litteraturundervisning, litterær kompetanse, empirisk litteraturteori, lesarresponsAbstractThe article discusses a key issue in literature didactics, namely the relation between literary reading as an academic competence, and literary reading as an experience. The discussion draws heavily on Louise Rosenblatt’s work. By using the concepts efferent and aesthetic reading, she shows how it is a challenge for the teacher of literature to develop literature teaching that adequately takes emotions and experience into account. In a literature-theoretical context, subjective responses to literary texts are irrelevant; but in a didactics context, the subjective responses are highly relevant.  This article contributes to the discussion by bringing in a more empirically based literature theory as a frame of reference. The article presents three readers’ literary responses, and shows how knowledge of individual reader responses can be the basis for

    2012-01-01

    The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) is a new structured professional judgment guide for assessing short-term risks in adolescents. The scheme may be distinguished from other youth risk assessment and treatment planning instruments by its inclusion of 23 dynamic factors that are each rated for both vulnerability and strength. In addition, START:AV is also unique in that it focuses on multiple adverse outcomes-namely, violence, self-harm, suicide, unauthorized leave, substance abuse, self-neglect, victimization, and general offending-over the short-term (i.e., weeks to months) rather than long-term (i.e., years). This paper describes a pilot implementation and preliminary evaluation of START:AV in three secure juvenile correctional facilities in the southern United States. Specifically, we examined the descriptive characteristics and psychometric properties of START:AV assessments completed by 21 case managers on 291 adolescent offenders (250 boys and 41 girls) at the time of admission. Results provide preliminary support for the feasibility of completing START:AV assessments as part of routine practice. Findings also highlight differences in the characteristics of START:AV assessments for boys and girls and differential associations between the eight START:AV risk domains. Though results are promising, further research is needed to establish the reliability and validity of START:AV assessments completed in the field.

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node.

    Apolipoprotein A-V is a potent modulator of plasma triacylglycerol levels. To investigate the molecular basis for this phenomenon we explored the ability of apolipoprotein A-V, in most experiments complexed to disks of dimyristoylphosphatidylcholine, to interact with two members of the low density...... lipoprotein receptor family, the low density lipoprotein receptor-related protein and the mosaic type-1 receptor, SorLA. Experiments using surface plasmon resonance showed specific binding of both free and lipid-bound apolipoprotein A-V to both receptors. The binding was calcium dependent and was inhibited......, apolipoprotein A-V (Arg210Glu/Lys211Gln), showed decreased binding to heparin and decreased ability to bind the low density lipoprotein receptor-related protein. Association of apolipoprotein A-V with the low density lipoprotein receptor-related protein or SorLA resulted in enhanced binding of human chylomicrons...

    To study the usefulness of 18 F-AV-1451 PET in patients with corticobasal syndrome (CBS). We recruited 8 patients with CBS, 17 controls, 31 patients with Alzheimer disease (AD), and 11 patients with progressive supranuclear palsy (PSP) from the Swedish BioFINDER study. All patients underwent clinical assessment, 18 F-AV-1451 PET, MRI, and quantification of β-amyloid pathology. A subset of participants also underwent 18 F-FDG-PET. In the 8 patients with CBS, 6 had imaging findings compatible with the corticobasal degeneration pathology and 2 with typical AD pathology. In the 6 patients with CBS without typical AD pathology, there were substantial retentions of 18 F-AV-1451 in the motor cortex, corticospinal tract, and basal ganglia contralateral to the most affected body side. These patients could be clearly distinguished from patients with AD dementia or PSP using 18 F-AV-1451. However, cortical atrophy was more widespread than the cortical retention of 18 F-AV1451 in these CBS cases, and cortical AV-1451 uptake did not correlate with cortical thickness or glucose hypometabolism. These results are in sharp contrast to AD dementia, where 18 F-AV-1451 retention was more widespread than cortical atrophy, and correlated well with cortical thickness and hypometabolism. Patients with CBS without typical AD pathology exhibited AV-1451 retention in the motor cortex, corticospinal tract, and basal ganglia contralateral to the affected body side, clearly different from controls and patients with AD dementia or PSP. However, cortical atrophy measured with MRI and decreased 18 F-fluorodeoxyglucose uptake were more widespread than 18 F-AV-1451 uptake and probably represent earlier, yet less specific, markers of CBS. This study provides Class III evidence that 18 F-AV-1451 PET distinguishes between CBS and AD or PSP. Copyright © 2017 The Author(s).

    The [ 18 F]AV-1451 positron emission tomography ligand allows the in vivo assessment of tau proteins in the brain. It shows strong binding in Alzheimer's dementia, but little is known about how it performs in progressive supranuclear palsy, a primary 4R tauopathy. The objectives of this study were to determine whether [ 18 F]AV-1451 uptake can be observed in progressive supranuclear palsy and to characterize the regional distribution when compared with controls and Alzheimer's dementia. [ 18 F]AV-1451 positron emission tomography was performed in 10 patients with probable progressive supranuclear palsy. These patients were age- and gender-matched to 50 controls and 10 Alzheimer's dementia patients who had undergone identical [ 18 F]AV-1451 imaging. Regional comparisons of [ 18 F]AV-1451 uptake were performed across the whole brain using region-of-interest and voxel-level analyses, and correlations between regional [ 18 F]AV-1451 and the progressive supranuclear palsy rating scale were assessed. An elevated [ 18 F]AV-1451 signal was observed in progressive supranuclear palsy when compared with controls in the pallidum, midbrain, dentate nucleus of the cerebellum, thalamus, caudate nucleus, and frontal regions. Signal in the cerebellar dentate and pallidum were also greater in progressive supranuclear palsy when compared with Alzheimer's dementia. Conversely, the [ 18 F]AV-1451 signal across the cortex was higher in Alzheimer's dementia when compared with progressive supranuclear palsy. The [ 18 F]AV-1451 signal in a number of regions correlated with the progressive supranuclear palsy rating scale. Progressive supranuclear palsy is associated with an elevated [ 18 F]AV-1451 signal in a characteristic and distinct regional pattern that correlates with disease severity and differs from the patterns observed in Alzheimer's dementia. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

  4. BMP2 expression in the endocardial lineage is required for AV endocardial cushion maturation and remodeling.

    Distal outgrowth, maturation and remodeling of the endocardial cushion mesenchyme in the atrioventricular (AV) canal are the essential morphogenetic events during four-chambered heart formation. Mesenchymalized AV endocardial cushions give rise to the AV valves and the membranous ventricular septum (VS). Failure of these processes results in several human congenital heart defects. Despite this clinical relevance, the mechanisms governing how mesenchymalized AV endocardial cushions mature and remodel into the membranous VS and AV valves have only begun to be elucidated. The role of BMP signaling in the myocardial and secondary heart forming lineage has been well studied; however, little is known about the role of BMP2 expression in the endocardial lineage. To fill this knowledge gap, we generated Bmp2 endocardial lineage-specific conditional knockouts (referred to as Bmp2 cKO Endo ) by crossing conditionally-targeted Bmp2 flox/flox mice with a Cre-driver line, Nfatc1 Cre , wherein Cre-mediated recombination was restricted to the endocardial cells and their mesenchymal progeny. Bmp2 cKO Endo mouse embryos did not exhibit failure or delay in the initial AV endocardial cushion formation at embryonic day (ED) 9.5-11.5; however, significant reductions in AV cushion size were detected in Bmp2 cKO Endo mouse embryos when compared to control embryos at ED13.5 and ED16.5. Moreover, deletion of Bmp2 from the endocardial lineage consistently resulted in membranous ventricular septal defects (VSDs), and mitral valve deficiencies, as evidenced by the absence of stratification of mitral valves at birth. Muscular VSDs were not found in Bmp2 cKO Endo mouse hearts. To understand the underlying morphogenetic mechanisms leading to a decrease in cushion size, cell proliferation and cell death were examined for AV endocardial cushions. Phospho-histone H3 analyses for cell proliferation and TUNEL assays for apoptotic cell death did not reveal significant differences between control and

    The genesis of complex ventricular rhythms during atrial tachyarrhythmias in humans is not fully understood. To clarify the dynamics of atrioventricular (AV) conduction in response to a regular high-rate atrial activation, 29 episodes of spontaneous or pacing-induced atrial flutter (AFL), covering a wide range of atrial rates (cycle lengths from 145 to 270 ms), were analyzed in 10 patients. AV patterns were identified by applying firing sequence and surrogate data analysis to atrial and ventricular activation series, whereas modular simulation with a difference-equation AV node model was used to correlate the patterns with specific nodal properties. AV node response at high atrial rate was characterized by 1) AV patterns of decreasing conduction ratios at the shortening of atrial cycle length (from 236.3 ± 32.4 to 172.6 ± 17.8 ms) according to a Farey sequence ordering (conduction ratio from 0.34 ± 0.12 to 0.23 ± 0.06; P AV block patterns occurring during regular atrial tachyarrhythmias. The characterization of AV nodal function during different AFL forms constitutes an intermediate step toward the understanding of complex ventricular rhythms during atrial fibrillation.

    Development of AV-block is a frequent complication associated with transcatheter aortic valve implantation (TAVI). To date little is known about the predictive value of the HV-interval prior to TAVI with respect to the risk of AV-block development. HV-interval was determined in 25 consecutive elderly patients with severe aortic valve stenosis (AS) before and immediately after TAVI. All patients subsequently underwent TAVI and 8 of these 25 patients (32%) developed complete AV-block during the TAVI procedure requiring permanent pacemaker implantation. Six of these 8 patients (75%) had marked HV prolongation (>54 ms). Pre-procedural HV-interval was significantly prolonged in the subgroup developing complete AV-block (62.1 ms±13.0 vs 49.2 ms±12.9; P=0.029). Prolongation of the HV-interval above 54 ms was associated with a higher rate of complete AV-block (sensitivity 75.0%, specificity 77.8%, P=0.01). HV-interval was prolonged in approximately one third of our elderly patients with aortic valve stenosis and associated with a high rate of complete AV-block following TAVI. HV-interval is easily obtained during TAVI screening procedures, thus facilitating identification of patients at risk for complete AV-block due to TAVI and consequently enabling bespoke risk management.

    Sediment treatment and sediment storage may alter sediment toxicity, and consequently biotic response. Purpose of our study was to combine these three aspects (treatment-toxicity-biotic response) in one integrated approach. We used Acid Volatile Sulfide (AVS) concentrations as a proxy of the disturbance of the sediment. AVS and Simultaneously Extracted Metal (SEM) concentrations were compared to bioassay responses with the freshwater benthic macroinvertebrate Asellus aquaticus. Storage conditions and sediment treatment affected AVS but not SEM levels. AVS can be used as a proxy for sediment disturbance. The best way to pretreat the sediment for use in a bioassay in order to maintain initial AVS conditions was to sample the sediment with an Ekman grab, immediately store it in a jar without headspace, and freeze it as soon as possible. In a survey using seven different sediments, bioassay responses of A. aquaticus were correlated with SEM and AVS characteristics. - Change in AVS is a good proxy for sediment disturbance and combined with SEM it can be used as a suitable predictor for biotic effects of sediment contamination.

    Accumulation of cortical and subcortical tau pathology is the primary pathological substrate for progressive supranuclear palsy (PSP). 18 F-AV-1451, a radiotracer that binds to the pathological tau protein, may be helpful for in vivo visualization and quantitation of tau pathology in PSP. The objectives of this study were to investigate cortical and subcortical 18 F-AV-1451 binding patterns in patients with PSP. We recruited 14 PSP patients and compared their cortical and subcortical binding patterns in 18 F-AV-1451 positron emission tomography (PET) studies with those of 15 Parkinson's disease (PD) patients and 15 healthy controls. In both the PD and PSP groups, subcortical 18 F-AV-1451 binding did not correlate with the severity of motor dysfunctions, and cortical binding did not differ between the controls and each patient group. However, the PSP patients showed greater 18 F-AV-1451 binding in the putamen, globus pallidus, subthalamic nucleus, and dentate nucleus when compared with the controls, whereas the PD patients showed lower 18 F-AV-1451 binding in the substantia nigra than controls. The PSP and PD patients showed distinct subcortical 18 F-AV-1451 binding patterns reflecting subcortical tau pathology in PSP and reduced nigral neuromelanin in PD. However, there was no correlation with the severity of motor dysfunction, no cortical regions with increased binding in PSP patients, and variable degrees of subcortical binding even in the controls. Therefore, the 18 F-AV-1451 PET may be less than ideal for assessing tau pathology in PSP. Further studies will be required to validate the clinical correlation and to understand the clinical utility of 18 F-AV-1451 PET for PSP patients. © 2016 International Parkinson and Movement Disorder Society. © 2016 International Parkinson and Movement Disorder Society.

    Objective To examine region and substrate-specific autoradiographic and in vitro binding patterns of PET tracer [F-18]-AV-1451 (previously known as T807), tailored to allow in vivo detection of paired helical filament tau-containing lesions, and to determine whether there is off-target binding to other amyloid/non-amyloid proteins. Methods We applied [F-18]-AV-1451 phosphor screen autoradiography, [F-18]-AV-1451 nuclear emulsion autoradiography and [H-3]-AV-1451 in vitro binding assays to the study of postmortem samples from patients with a definite pathological diagnosis of Alzheimer’s disease, frontotemporal lobar degeneration-tau, frontotemporal lobar degeneration-TDP-43, progressive supranuclear palsy, corticobasal degeneration, dementia with Lewy bodies, multiple system atrophy, cerebral amyloid angiopathy and elderly controls free of pathology. Results Our data suggest that AV-1451 strongly binds to tau lesions primarily made of paired helical filaments in Alzheimer’s brains e.g. intra and extraneuronal tangles and dystrophic neurites, but does not seem to bind to a significant extent to neuronal and glial inclusions mainly composed of straight tau filaments in non-Alzheimer tauopathy brains or to β-amyloid, α-synuclein or TDP-43-containing lesions. AV-1451 off-target binding to neuromelanin- and melanin-containing cells and, to a lesser extent, to brain hemorrhagic lesions was identified. Interpretation Our data suggest that AV-1451 holds promise as surrogate marker for the detection of brain tau pathology in the form of tangles and paired helical filament-tau-containing neurites in Alzheimer’s brains but also point to its relatively lower affinity for lesions primarily made of straight tau filaments in non-Alzheimer tauopathy cases and to the existence of some AV-1451 off-target binding. These findings provide important insights for interpreting in vivo patterns of [F-18]-AV-1451 retention. PMID:26344059

    To assess [ 18 F]AV-1451 tau-PET (positron emission tomography) uptake patterns across the primary progressive aphasia (PPA) variants (logopenic, semantic, and agrammatic), examine regional uptake patterns of [ 18 F]AV-1451 independent of clinical diagnosis, and compare the diagnostic utility of [ 18 F]AV-1451, [ 18 F]-fluorodeoxygluclose (FDG)-PET and MRI (magnetic resonance imaging) to differentiate the PPA variants. We performed statistical parametric mapping of [ 18 F]AV-1451 across 40 PPA patients (logopenic-PPA = 14, semantic-PPA = 13, and agrammatic-PPA = 13) compared to 80 cognitively normal, Pittsburgh compound B-negative controls, age and gender matched 2:1. Principal component analysis of regional [ 18 F]AV-1451 tau-PET standard uptake value ratio was performed to understand underlying patterns of [ 18 F]AV-1451 uptake independent of clinical diagnosis. Penalized multinomial regression analyses were utilized to assess diagnostic utility. Logopenic-PPA showed striking uptake throughout neocortex, particularly temporoparietal, compared to controls, semantic-PPA, and agrammatic-PPA. Semantic-PPA and agrammatic-PPA showed milder patterns of focal [ 18 F]AV-1451 uptake. Semantic-PPA showed elevated uptake (left>right) in anteromedial temporal lobes, compared to controls and agrammatic-PPA. Agrammatic-PPA showed elevated uptake (left>right) throughout prefrontal white matter and in subcortical gray matter structures, compared to controls and semantic-PPA. The principal component analysis of regional [ 18 F]AV-1451 indicated two primary dimensions, a severity dimension that distinguished logopenic-PPA from agrammatic-PPA and semantic-PPA, and a frontal versus temporal contrast that distinguishes agrammatic-PPA and semantic-PPA cases. Diagnostic utility of [ 18 F]AV-1451was superior to MRI and at least equal to FDG-PET. [ 18 F]AV-1451binding characteristics differ across the PPA variants and were excellent at distinguishing between the variants. [ 18

    Tuberous sclerosis is a neurologic disease affecting various organs with a triade: sebaceum adenoma, mental retardation and seizures. This report presents a case of a patient with tuberous sclerosis and third degree A-V block with complete invasive and non-invasive evaluation. The patient had sincope and complete A-V block with QRS complexes showing right bundle branch block morphology. The echocardiogram showed dilated cardiomyopathy with diffuse left ventricular dysfunction and had normal coronary arteriography. The eletrophysiologic evaluation showed complete infra-hisian A-V block and QRS with left bundle branch block pattern with normal sinus nodal and A-V nodal function. It was not possible to induce ventricular tachtyarrhythmias up to two extrastimuli. Histologic study showed normal myocardium under light and electronic microscopy. After permanent VVI pacemaker implant, the patient in follow-up for 16 years. This case seems to be the first in the international medical literature of tuberous sclerosis with complete heart block.

    Dammar är en viktig konstruktion i Sverige och i världen bland annat för vattenförsörjning, reglering av flöden och elproduktion. En expansion på grund av en alkalisilikareaktion (ASR) i en betongdamm kan leda till många problem. Bland annat kan det uppstå läckage av vatten och problem med öppning och stängning av luckor. Mycket forskning har lagts ner på att ta reda på hur ASR påverkar hållfastheten och bärförmågan hos betong. Detta examensarbete syftar till att genom en litteraturstudie vis...

    This study investigated binding of [ 18 F]AV-1451 to neuromelanin in the substantia nigra of patients with Parkinson's disease (PD) and progressive supranuclear palsy (PSP). [ 18 F]AV-1451 is a positron emission tomography radiotracer designed to bind pathological tau. A post-mortem study using [ 18 F]AV-1451 discovered off-target binding properties to neuromelanin in the substantia nigra. A subsequent clinical study reported a 30% decrease in [ 18 F]AV-1451 binding in the midbrain of PD patients. A total of 12 patients and 10 healthy age-matched controls were recruited. An anatomical MRI and a 90-min PET scan, using [ 18 F]AV-1451, were acquired from all participants. The standardized uptake value ratio (SUVR) from 60 to 90 min post-injection was calculated for the substantia nigra, using the cerebellar cortex as the reference region. The substantia nigra was delineated using automated region of interest software. An independent samples ANOVA and LSD post hoc testing were used to test for differences in [ 18 F]AV-1451 SUVR between groups. Substantia nigra SUVR from 60 to 90 min was significantly greater in HC compared to both PSP and PD groups. Although the PD group had the lowest SUVR, there was no significant difference in substantia nigra uptake between PD and PSP. [ 18 F]AV-1451 may be the first PET radiotracer capable of imaging neurodegeneration of the substantia nigra in parkinsonisms. Further testing must be done in PD and atypical parkinsonian disorders to support this off-target use of [ 18 F]AV-1451.

    The causal relationship between atrial and ventricular activities during human atrial fibrillation (AF) is poorly understood. This study analyzed the effects of an increase in atrial rate on the link between atrial and ventricular activities during AF. Atrial and ventricular time series were determined in 14 patients during the spontaneous acceleration of the atrial rhythm at AF onset. The dynamic relationship between atrial and ventricular activities was quantified in terms of atrioventricular (AV) coupling by AV synchrogram analysis. The technique identified n:m coupling patterns (n atrial beats in m ventricular cycles), quantifying their percentage, maximal length, and conduction ratio (= m/n). Simulations with a difference-equation AV model were performed to correlate the observed dynamics to specific atrial/nodal properties. The atrial rate increase significantly affected AV coupling and ventricular response during AF. The shortening of atrial intervals from 185 ± 32 to 165 ± 24 ms (P AV patterns with progressively decreasing m/n ratios (from conduction ratio = 0.34 ± 0.09 to 0.29 ± 0.08, P AV block and coupling instability at higher atrial rates were associated with increased ventricular interval variability (from 123 ± 52 to 133 ± 55 ms, P AV pattern transitions and coupling instability in patients were predicted, assuming the filtering of high-rate irregular atrial beats by the slow recovery of nodal excitability. These results support the role of atrial rate in determining AV coupling and ventricular response and may have implications for rate control in AF.

    [F-18]-AV-1451, a PET tracer specifically developed to detect brain neurofibrillary tau pathology, has the potential to facilitate accurate diagnosis of Alzheimer's disease (AD), staging of brain tau burden and monitoring disease progression. Recent PET studies show that patients with mild cognitive impairment and AD dementia exhibit significantly higher in vivo [F-18]-AV-1451 retention than cognitively normal controls. Importantly, PET patterns of [F-18]-AV-1451 correlate well with disease severity and seem to match the predicted topographic Braak staging of neurofibrillary tangles (NFTs) in AD, although this awaits confirmation. We studied the correlation of autoradiographic binding patterns of [F-18]-AV-1451 and the stereotypical spatiotemporal pattern of progression of NFTs using legacy postmortem brain samples representing different Braak NFT stages (I-VI). We performed [F-18]-AV-1451 phosphor-screen autoradiography and quantitative tau measurements (stereologically based NFT counts and biochemical analysis of tau pathology) in three brain regions (entorhinal cortex, superior temporal sulcus and visual cortex) in a total of 22 cases: low Braak (I-II, n = 6), intermediate Braak (III-IV, n = 7) and high Braak (V-VI, n = 9). Strong and selective [F-18]-AV-1451 binding was detected in all tangle-containing regions matching precisely the observed pattern of PHF-tau immunostaining across the different Braak stages. As expected, no signal was detected in the white matter or other non-tangle containing regions. Quantification of [F-18]-AV-1451 binding was very significantly correlated with the number of NFTs present in each brain region and with the total tau and phospho-tau content as reported by Western blot and ELISA. [F-18]-AV-1451 is a promising biomarker for in vivo quantification of brain tau burden in AD. Neuroimaging-pathologic studies conducted on postmortem material from individuals imaged while alive are now needed to confirm these observations.

    Empiric programming of the atrio-ventricular (AV) delay is commonly performed during pacemaker implantation. Transmitral flow assessment by Doppler echocardiography can be used to find the optimal AV delay by Ritter's method, but this cannot easily be performed during pacemaker implantation. We sought to determine a non-invasive surrogate for this assessment. Since electrocardiographic P-wave duration estimates atrial activation time, we hypothesized this measurement may provide a more appropriate basis for programming AV intervals. A total of 19 patients were examined at the time of dual chamber pacemaker implantation, 13 (68%) being male with a mean age of 77. Each patient had the optimal AV interval determined by Ritter's method. The P-wave duration was measured independently on electrocardiograms using MUSE® Cardiology Information System (version 7.1.1). The relationship between P-wave duration and the optimal AV interval was analyzed. The P-wave duration and optimal AV delay were related by a correlation coefficient of 0.815 and a correction factor of 1.26. The mean BMI was 27. The presence of hypertension, atrial fibrillation, and valvular heart disease was 13 (68%), 3 (16%), and 2 (11%) respectively. Mean echocardiographic parameters included an ejection fraction of 58%, left atrial index of 32 ml/m(2), and diastolic dysfunction grade 1 (out of 4). In patients with dual chamber pacemakers in AV sequentially paced mode and normal EF, electrocardiographic P-wave duration correlates to the optimal AV delay by Ritter's method by a factor of 1.26.

    Morphine-induced glial proinflammatory responses have been documented to contribute to tolerance to opioid analgesia. Here, we examined whether drugs previously shown to suppress glial proinflammatory responses can alter other clinically relevant opioid effects; namely, withdrawal or acute analgesia. AV411 (ibudilast) and minocycline, drugs with distinct mechanisms of action that result in attenuation of glial proinflammatory responses, each reduced naloxone-precipitated withdrawal. Analysis of brain nuclei associated with opioid withdrawal revealed that morphine altered expression of glial activation markers, cytokines, chemokines, and a neurotrophic factor. AV411 attenuated many of these morphine-induced effects. AV411 also protected against spontaneous withdrawal-induced hyperactivity and weight loss recorded across a 12-day timecourse. Notably, in the spontaneous withdrawal study, AV411 treatment was delayed relative to the start of the morphine regimen so to also test whether AV411 could still be effective in the face of established morphine dependence, which it was. AV411 did not simply attenuate all opioid effects, as co-administering AV411 with morphine or oxycodone caused three-to-five-fold increases in acute analgesic potency, as revealed by leftward shifts in the analgesic dose response curves. Timecourse analyses revealed that plasma morphine levels were not altered by AV411, suggestive that potentiated analgesia was not simply due to prolongation of morphine exposure or increased plasma concentrations. These data support and extend similar potentiation of acute opioid analgesia by minocycline, again providing converging lines of evidence of glial involvement. Hence, suppression of glial proinflammatory responses can significantly reduce opioid withdrawal, while improving analgesia.

    Cardio neuroablation (CNA) is a lesser-known technique for management of patients with excessive vagal activation on the basis of radiofrequency catheter ablation (RFCA) of the areas related to the three main autonomic ganglia around the heart. We investigated the effectiveness of selective and/or stepwise RFCA of these areas via right atrium (RA) and/or left atrium (LA) in the patients with recurrent syncope due to excessive vagal activity. Twenty-two patients presenting symptomatic functional bradyarrhythmias, neurally mediated reflex syncope (NMS), symptomatic atrioventricular (AV) block, and symptomatic sinus node dysfunction (SND; number = 8, 7, 7, respectively) were enrolled. The three main paracardiac ganglia were targeted via RA and LA in the patients with NMS and SND. The procedure was performed via RA in the patients with AV block, followed by RFCA of all ganglia via LA, if AV conduction disorder persists. The sites showing fragmented potentials were identified by electrical mapping and verified by high-frequency stimulation and ablated until atrial electrical potential was completely eliminated (AV block. Despite the increased heart rate, the resolution of AV block after the RFCA could not be achieved in one patient who had partial resolution with atropine infusion on admission. CNA may be an alternative and safe strategy to reduce NMS episodes, and to treat functional AV block and symptomatic SND, especially in young patients. © 2015 Wiley Periodicals, Inc.

    Distal outgrowth and maturation of mesenchymalized endocardial cushions are critical morphogenetic events during post-EMT atrioventricular (AV) valvuloseptal morphogenesis. We explored the role of BMP-2 in the regulation of valvulogenic extracellular matrix (ECM) components, versican and hyaluronan (HA), and cell migration during post-EMT AV cushion distal outgrowth/expansion. We observed intense staining of versican and HA in AV cushion mesenchyme from the early cushion expansion stage, Hamburger and Hamilton (HH) stage-17 to the cushion maturation stage, HH stage-29 in the chick. Based on this expression pattern we examined the role of BMP-2 in regulating versican and HA using 3D AV cushion mesenchymal cell (CMC) aggregate cultures on hydrated collagen gels. BMP-2 induced versican expression and HA deposition as well as mRNA expression of versican and Has2 by CMCs in a dose dependent manner. Noggin, an antagonist of BMP, abolished BMP-2-induced versican and HA as well as mRNA expression of versican and Has2. We further examined whether BMP-2-promoted cell migration was associated with expression of versican and HA. BMP-2- promoted cell migration was significantly impaired by treatments with versican siRNA and HA oligomer. In conclusion, we provide evidence that BMP-2 induces expression of versican and HA by AV CMCs and that these ECM components contribute to BMP-2-induced CMC migration, indicating critical roles for BMP-2 in distal outgrowth/expansion of mesenchymalized AV cushions.

    Device optimization is not routinely performed in patients who underwent cardiac resynchronization therapy (CRT) device implantation. Noninvasive optimization of CRT devices by measurement of cardiac output (CO) can be used as a simple method to assess ventricular systolic performance. The aim of this study was to assess whether optimization of atrioventricular (AV) and interventricular (VV) delay can improve hemodynamic response to CRT and whether this optimization should be performed for each patient individually. Twenty patients with advanced heart failure New York Heart Association (NYHA) class III/IV, left ventricular ejection fraction ≤ 35% and left bundle branch block (QRS ≥ 120 ms) in sinus rhythm were evaluated from 24 h to 48 h after implantation of a CRT device by means of impedance cardiography (ICG). CO was first measured at each patient's intrinsic rhythm. Patients then underwent adjustments of AV and VV delay from 80 ms to 140 ms and from -60 ms to +60 ms, respectively in 20 ms increment steps and CO at each setting was measured by ICG. Both AV and VV delays were programmed according to the greatest improvement in CO compared to intrinsic rhythm. There was a statistically signifi cant increase in CO measured at the intrinsic rhythm compared to different AV delay by mean of 21% (3.8 ± 1.0 vs. 4.6 ± 0.1 L/min, p AV/VV delays with left ventricle-preexcitation or simultaneous biventricular pacing caused additional increased CO from intrinsic rhythm by mean of 32.6% (3.8 ± 1.0 vs. 5.04 ± ± 1.0 L/min, p AV/VV setting delays also resulted in improved hemodynamic responses compared to VV factory setting delay. Both AV and VV delay optimization should be performed in clinical practice. Optimal AV delay improved outcome. However, combination of optimized AV/VV delays provided the best hemodynamic response. Optimized AV/VV delays with left ventricle-preexcitation or simultaneous biventricular pacing increased hemodynamic output compared to intrinsic

    A 91-year-old woman received a dual-chamber pacemaker for sick sinus syndrome and intermittently abnormal atrioventricular (AV) conduction. The pacemaker was set in DDI mode with a 350-ms AV delay to preserve intrinsic ventricular activity. She complained of palpitation during AV sequential pacing. The electrocardiogram showed a 2:1 AV rhythm from 1:1 ventriculoatrial (VA) conduction during ventricular pacing in DDI mode with a long AV interval. After reprogramming of the pacemaker in DDD mode with a 250-ms AV interval and additional 100-ms prolongation of the AV interval by the ventricular intrinsic preference function, VA conduction disappeared and the patient's symptom were alleviated without increasing unnecessary right ventricular pacing. ©2011, The Authors.

    The atrioventricular (AV) node conducts slowly and has a long refractory period. These features sustain the filtering of atrial impulses and hence are often modulated to optimize ventricular rate during supraventricular tachyarrhythmias. The AV node is also the site of a clinically common reentrant arrhythmia. Its function is assessed for a variety of purposes from its responses to a premature protocol (S1S2, test beats introduced at different cycle lengths) repeatedly performed at different basic rates and/or to an incremental pacing protocol (increasingly faster rates). Puzzlingly, resulting data and interpretation differ with protocols as well as with chosen recovery and refractory indexes, and are further complicated by the presence of built-in fast and slow pathways. This problem applies to endocavitary investigations of arrhythmias as well as to many experimental functional studies. This review supports an integrated framework of rate-dependent and dual pathway AV nodal function that can account for these puzzling characteristics. The framework was established from AV nodal responses to S1S2S3 protocols that, compared with standard S1S2 protocols, allow for an orderly quantitative dissociation of the different factors involved in changes in AV nodal conduction and refractory indexes under rate-dependent and dual pathway function. Although largely based on data from experimental studies, the proposed framework may well apply to the human AV node. In conclusion, the rate-dependent and dual pathway properties of the AV node can be integrated within a common functional framework the contribution of which to individual responses can be quantitatively determined with properly designed protocols and analytic tools.

    Accessory AV-connections capable of antegrade conduction need to be recognized because of the potential for life-threatening arrhythmias. However, the preexcited ECG pattern may be subtle, especially among left-sided AV-connections. We explored whether additional ECG criteria might help identify left-sided AV-connections. We analyzed 156 patients who underwent an electrophysiology study (EPS) and ablation for paroxysmal supraventricular tachycardias (PSVT). Patients were divided into 2 groups: those with left-sided AV-connections (Group 1) and all other PSVT (Group 2). Various ECG parameters were compared before and after ablation in both groups. The EPS identified left-sided AV-connections among 43 patients (Group 1) and excluded it among 113 (Group 2). Baseline ECG in Group 1 demonstrated obvious preexcitation among 24/43 patients (55.8%), the remaining 19/43 missing obvious preexcitation. R/S ratio > 0.5 in V1 was noted in 38/43 (88.4%) patients in Group 1 before ablation (median 1.00; IQR 0.58-2.20), including 16/19 (84.2%) patients lacking obvious left-sided AVconnections. Conversely, only 10/113 (8.8%) patients in Group 2 had R/S ratios in V1 ≥ 0.5 (0.20; 0.10-0.31), P AV-connections (sensitivity 93.0%). The negative predictive value of this combined criterion was 103/106 (97.2%). In symptomatic patients, combining the R/S ratio (≥ 0.5) in lead V1 with the classic preexcitation pattern on ECG markedly improved the sensitivity to diagnose left-sided AV-connections. This ratio may be particularly useful among patients lacking obvious preexcitation. © 2015 Wiley Periodicals, Inc.

    In this study, we designed and tested a new algorithm, which we call the 'restricted parabola', to identify the optimum atrioventricular (AV) delay in patients with biventricular pacemakers. This algorithm automatically restricts the hemodynamic data used for curve fitting to the parabolic zone in order to avoid inadvertently selecting an AV optimum that is too long.We used R, a programming language and software environment for statistical computing, to create an algorithm which applies multiple different cut-offs to partition curve fitting of a dataset into a parabolic and a plateau region and then selects the best cut-off using a least squares method. In 82 patients, AV delay was adjusted and beat-to-beat systolic blood pressure (SBP) was measured non-invasively using our multiple-repetition protocol. The novel algorithm was compared to fitting a parabola across the whole dataset to identify how many patients had a plateau region, and whether a higher hemodynamic response was achieved with one method.In 9/82 patients, the restricted parabola algorithm detected that the pattern was not parabolic at longer AV delays. For these patients, the optimal AV delay predicted by the restricted parabola algorithm increased SBP by 1.36 mmHg above that predicted by the conventional parabolic algorithm (95% confidence interval: 0.65 to 2.07 mmHg, p-value = 0.002).AV optima selected using our novel restricted parabola algorithm give a greater improvement in acute hemodynamics than fitting a parabola across all tested AV delays. Such an algorithm may assist the development of automated methods for biventricular pacemaker optimisation.

    Atrioventricular (AV) interval optimization is often deemed too time-consuming in dual-chamber pacemaker patients with maintained LV function. Thus the majority of patients are left at their default AV interval. To quantify the magnitude of hemodynamic improvement following AV interval optimization in chronically paced dual chamber pacemaker patients. A pressure volume catheter was placed in the left ventricle of 19 patients with chronic dual chamber pacing and an ejection fraction >45 % undergoing elective coronary angiography. AV interval was varied in 10 ms steps from 80 to 300 ms, and pressure volume loops were recorded during breath hold. The average optimal AV interval was 152 ± 39 ms compared to 155 ± 8 ms for the average default AV interval (range 100-240 ms). The average improvement in stroke work following AV interval optimization was 935 ± 760 mmHg/ml (range 0-2,908; p AV interval changes the average stroke work by 207 ± 162 mmHg/ml. AV interval optimization also leads to improved systolic dyssynchrony indices (17.7 ± 7.0 vs. 19.4 ± 7.1 %; p = 0.01). The overall hemodynamic effect of AV interval optimization in patients with maintained LV function is in the same range as for patients undergoing cardiac resynchronization therapy for several parameters. The positive effect of AV interval optimization also applies to patients who have been chronically paced for years.

    The ability to assess the distribution and extent of tau pathology in Alzheimer's disease and progressive supranuclear palsy in vivo would help to develop biomarkers for these tauopathies and clinical trials of disease-modifying therapies. New radioligands for positron emission tomography have generated considerable interest, and controversy, in their potential as tau biomarkers. We assessed the radiotracer 18F-AV-1451 with positron emission tomography imaging to compare the distribution and intensity of tau pathology in 15 patients with Alzheimer's pathology (including amyloid-positive mild cognitive impairment), 19 patients with progressive supranuclear palsy, and 13 age- and sex-matched controls. Regional analysis of variance and a support vector machine were used to compare and discriminate the clinical groups, respectively. We also examined the 18F-AV-1451 autoradiographic binding in post-mortem tissue from patients with Alzheimer's disease, progressive supranuclear palsy, and a control case to assess the 18F-AV-1451 binding specificity to Alzheimer's and non-Alzheimer's tau pathology. There was increased 18F-AV-1451 binding in multiple regions in living patients with Alzheimer's disease and progressive supranuclear palsy relative to controls [main effect of group, F(2,41) = 17.5, P AV-1451 binding was significantly increased in patients with Alzheimer's disease, relative to patients with progressive supranuclear palsy and with control subjects, in the hippocampus and in occipital, parietal, temporal, and frontal cortices (t's > 2.2, P's AV-1451 binding was elevated in the midbrain (t = 2.1, P AV-1451 uptake in the putamen, pallidum, thalamus, midbrain, and in the dentate nucleus of the cerebellum (t's > 2.7, P's AV-1451 strongly bound to Alzheimer-related tau pathology, but less specifically in progressive supranuclear palsy. 18F-AV-1451 binding to the basal ganglia was strong in all groups in vivo.

    The mechanism of bacterial resistance to tributyltin (TBT) is still unclear. The results herein presented contribute to clarify that mechanism in the TBT-resistant bacterium Aeromonas molluscorum Av27. We have identified and cloned a new gene that is involved in TBT resistance in this strain. The gene is highly homologous (84%) to the Aeromonas hydrophila-sugE gene belonging to the small multidrug resistance gene family (SMR), which includes genes involved in the transport of lipophilic drugs. In Av27, expression of the Av27-sugE was observed at the early logarithmic growth phase in the presence of a high TBT concentration (500 μM), thus suggesting the contribution of this gene for TBT resistance. E. coli cells transformed with Av27-sugE become resistant to ethidium bromide (EtBr), chloramphenicol (CP) and tetracycline (TE), besides TBT. According to the Moriguchi logP (miLogP) values, EtBr, CP and TE have similar properties and are substrates for the sugE-efflux system. Despite the different miLogP of TBT, E. coli cells transformed with Av27-sugE become resistant to this compound. So it seems that TBT is also a substrate for the SugE protein. The modelling studies performed also support this hypothesis. The data herein presented clearly indicate that sugE is involved in TBT resistance of this bacterium.

  5. Context-Aware UPnP-AV Services for Adaptive Home Multimedia Systems

    2008-01-01

    Full Text Available One possibility to provide mobile multimedia in domestic multimedia systems is the use of Universal Plug and Play Audio Visual (UPnP-AV devices. In a standard UPnP-AV scenario, multimedia content provided by a Media Server device is streamed to Media Renderer devices by the initiation of a Control Point. However, there is no provisioning of context-aware multimedia content customization. This paper presents an enhancement of standard UPnP-AV services for home multimedia environments regarding context awareness. It comes up with context profile definitions, shows how this context information can be queried from the Media Renderers, and illustrates how a Control Point can use this information to tailor a media stream from the Media Server to one or more Media Renderers. Moreover, since a standard Control Point implementation only queries one Media Server at a time, there is no global view on the content of all Media Servers in the UPnP-AV network. This paper also presents an approach of multimedia content integration on the Media Server side that provides fast search for content on the network. Finally, a number of performance measurements show the overhead costs of our enhancements to UPnP-AV in order to achieve the benefits.

    Topiwala, Pankaj; Dai, Wei; Krishnan, Madhu

    2017-09-01

    This paper describes a study to investigate possible ways to improve the AV1 codec, in several directions, most particularly in the context of 10-bit HDR video content, and 8/10 bit image content. Applications to SDR video, and 360 content are discussed elsewhere. For HDR content, a data adaptive grading technique in conjunction with the AV1 codec is studied. For image content, lapped biorthogonal transforms for (near) lossless compression is studied. For scalability-type applications, we introduce advanced resampling filters which outperform current ones. It is asserted that useful improvements are possible in each of these categories. In particular, substantial value is offered in the coding of HDR content, very competitive with HEVC HDR10, in a coding framework offering backwards compatibility with SDR. We also provide a rudimentary comparison of AV1 to the standard HEVC as well as the developing JVET codecs.

    Patients with probable dementia with Lewy bodies (DLB) often have Alzheimer's disease (AD)-related pathology. Our objective was to determine the pattern of positron emission tomography (PET) tau tracer AV-1451 uptake in patients with probable DLB, compared to AD, and its relationship to β-amyloid deposition on PET. Consecutive patients with clinically probable DLB (n = 19) from the Mayo Clinic Alzheimer's Disease Research Center underwent magnetic resonance imaging, AV-1451, and Pittsburgh compound-B (PiB) PET examinations. Age- and sex-matched groups of AD dementia (n = 19) patients and clinically normal controls (n = 95) from an epidemiological cohort served as a comparison groups. Atlas- and voxel-based analyses were performed. The AD dementia group had significantly higher AV-1451 uptake than the probable DLB group, and medial temporal uptake completely distinguished AD dementia from probable DLB. Patients with probable DLB had greater AV-1451 uptake in the posterior temporoparietal and occipital cortex compared to clinically normal controls, and in probable DLB, the uptake in these regions correlated with global cortical PiB uptake (Spearman rho = 0.63; p = 0.006). Medial temporal lobe AV-1451 uptake distinguishes AD dementia from probable DLB, which may be useful for differential diagnosis. Elevated posterior temporoparietal and occipital AV-1451 uptake in probable DLB and its association with global cortical PiB uptake suggest an atypical pattern of tau deposition in DLB.

    AV delay optimisation of biventricular pacing devices (cardiac resynchronisation therapy, CRT) is performed in trials and recommended by current guidelines. The Doppler echocardiographic iterative method is the most commonly recommended. Yet whether it can be executed reliably has never been tested formally. 36 multinational specialists, familiar with using the echocardiographic iterative method of CRT optimisation, were shown 20-40 sets of transmitral Doppler traces at 6-8 AV settings and asked to select the optimal AV delay. Unknown to the specialists, some Doppler datasets appeared in duplicate, allowing assessment of both inter and intra-specialist interpretation. On the Kappa scale of agreement (1 = perfect agreement, 0 = chance alone), the agreement regarding optimal AV delay between specialists was poor (kappa=0.12 ± 0.08). More importantly, agreement of specialists with themselves (i.e. viewing identical sets of traces, twice) was also poor, with Kappa=0.23 ± 0.07 and mean absolute difference in optimum AV delay of 83 ms between first and second viewing of the same traces. Iterative AV optimisation is not executed reliably by experts, even in an artificially simplified context where biological variability and variation in image acquisition are eliminated by use of identical traces. This cannot be blamed on insufficient skills of some experts or discordant methods of selecting the optimum, because operators also showed poor agreement with themselves when assessing the same trace. Instead, guidelines should retract any recommendation for this algorithm. Guideline-development processes might usefully begin with a rudimentary check on proposed algorithms, to establish at least minimal credibility. Copyright © 2012 Elsevier Ireland Ltd.

  15. The parsec-scale relationship between ICO and AV in local molecular clouds

    We measure the parsec-scale relationship between integrated CO intensity (ICO) and visual extinction (AV) in 24 local molecular clouds using maps of CO emission and dust optical depth from Planck. This relationship informs our understanding of CO emission across environments, but clean Milky Way measurements remain scarce. We find uniform ICO for a given AV, with the results bracketed by previous studies of the Pipe and Perseus clouds. Our measured ICO-AV relation broadly agrees with the standard Galactic CO-to-H2 conversion factor, the relation found for the Magellanic clouds at coarser resolution, and numerical simulations by Glover & Clark (2016). This supports the idea that CO emission primarily depends on shielding, which protects molecules from dissociating radiation. Evidence for CO saturation at high AV and a threshold for CO emission at low AV varies remains uncertain due to insufficient resolution and ambiguities in background subtraction. Resolution of order 0.1 pc may be required to measure these features. We use this ICO-AV relation to predict how the CO-to-H2 conversion factor (XCO) would change if the Solar Neighbourhood clouds had different dust-to-gas ratio (metallicity). The calculations highlight the need for improved observations of the CO emission threshold and H I shielding layer depth. They are also sensitive to the shape of the column density distribution. Because local clouds collectively show a self-similar distribution, we predict a shallow metallicity dependence for XCO down to a few tenths of solar metallicity. However, our calculations also imply dramatic variations in cloud-to-cloud XCO at subsolar metallicity.

    Physiological shortening of the atrioventricular (AV) interval with increasing heart rate is well documented in normal human beings and is an established component of dual-chamber pacing for bradycardia. To assess the effect of exercise on optimal AV delay and the impact of a patient-specific rate-adaptive AV delay (RAAVD) on exercise capacity in patients with heart failure following cardiac resynchronization therapy. Phase 1: We performed iterative AV optimization at rest and exercise in 52 cardiac resynchronization therapy patients in atrial-sensed mode (mean age 71.6 ± 9.2 years, 25% females). Phase 2: Subsequently, 20 consecutive volunteers from this group (mean age 69.2 ± 9.6 years, 15% females) underwent cardiopulmonary exercise testing with RAAVD individually programmed ON (RAAVD-ON) or OFF (RAAVD-OFF). Phase 1: In 94% of the patients, there was a marked reduction (mean 50%) in optimal AV delay with exercise. The optimal resting vs exercise AV delay was 114.2 ± 29 ms at a heart rate of 64.4 ± 7.1 beats/min vs 57 ± 31 ms at a heart rate of 103 ± 13 beats/min (P AV delay with exercise, and 3 (6%) showed no change. Phase 2: With RAAVD-ON, significantly better exercise times were achieved (8.7 ± 3.2 minutes) compared with RAAVD-OFF (7.9 ± 3.2 minutes; P = .003), and there was a significant improvement in Vo(2)max (RAAVD-ON 16.1 ± 4.0 vs RAAVD-OFF 14.9 ± 3.7 mL/(kg · min); P = .024). There was a dramatic reduction in optimal AV delay with physiological exercise in the majority of this heart failure cardiac resynchronization therapy cohort. Replicating this physiological response with a programmable RAAVD translated into a 10% improvement in exercise capacity. Copyright © 2012 Heart Rhythm Society. Published by Elsevier Inc.

  6. First-degree AV block-an entirely benign finding or a potentially curable cause of cardiac disease?

    Science.gov (United States)

    Holmqvist, Fredrik; Daubert, James P

    2013-05-01

    First-degree atrioventricular (AV) block is a delay within the AV conduction system and is defined as a prolongation of the PR interval beyond the upper limit of what is considered normal (generally 0.20 s). Up until recently, first-degree AV block was considered an entirely benign condition. In fact, some complain that it is a misnomer since there is only delay and no actual block in the AV conduction system (usually within the AV node). However, it has long been acknowledged that extreme forms of first-degree AV block (typically a PR interval exceeding 0.30 s) can cause symptoms due to inadequate timing of atrial and ventricular contractions, similar to the so-called pacemaker syndrome. Consequently, the current guidelines state that permanent pacemaker implantation is reasonable for first-degree AV block with symptoms similar to those of pacemaker syndrome or with hemodynamic compromise, but also stresses that there is little evidence to suggest that pacemakers improve survival in patients with isolated first-degree AV block. Recent reports suggest that it may be time to revisit the impact of first-degree AV block. Also, several findings in post hoc analyses of randomized device trials give important insights in possible treatment options. The present review aims to provide an update on the current knowledge concerning the impact of first-degree AV block and also to address the issue of pacing in patients with this condition. ©2013, Wiley Periodicals, Inc.

    Permanent AV-block is a recognized and feared complication of slow pathway modulation for AVNRT. We aimed to assess incidence of transient and permanent AV-block as well as consequences of transient AV-block in a large contemporary AVNRT ablation cohort. We searched our single center prospective ablation database for occurrence of transient and permanent AV-block during slow pathway modulation between January 2004 and October 2015. We analyzed patients' and procedural characteristics as well as outcome of patients in whom transient or permanent AV-block occurred. Of 9170 patients who underwent a catheter ablation at our institution between January 2004 and October 2015, 2101 patients (64% women, mean age 50±18years) underwent slow pathway modulation. In three patients, permanent AV-block occurred during RF application. Additional two patients had transient AV-block that recovered (after a few minutes and 25min), but recurred within two days of the procedure. All five patients underwent dual chamber pacemaker implantation (0.2%). Transient AV-block related to RF delivery occurred in 44 patients (2%). Transient mechanical AV-block occurred in additional 17 patients (0.8%). In 12 patients, ablation was continued despite transient AV-block. One of these patients developed permanent AV-block. Permanent AV-block following slow pathway modulation is a rare event, occurring in 0.2% of patients in a large contemporary single center cohort. Transient AV-block is more frequent (2%).

    Full Text Available Att öva för att lära sig att hantera polisiära situationer utgör ett viktigt inslag i polisstudenters utbildning. Lärandet sker genom praktiska övningar t.ex. drillövningar och övningar av specifika moment men även via simuleringar där studenter agerar som polis i mera komplexa situationer. Simuleringar är inte unika för polisutbildning utan utgör ett vanligt inslag i professionsutbildning genom sin koppling till "verkliga" situationer (Peters och Vissers, 2004; Lederman, 1984. Under de senaste årtiondena har simuleringar använts för utbildning inom så skilda professionsfält som medicin och hälsovård, flyg och blåljusverksamhet. Simuleringar kan vara av skiftande karaktär t.ex. fysiska i form av rollspel men även datorbaserade. Simuleringar kan syfta till att utveckla en specifik färdighet (se t.ex. Windsor, 2009; Stefanidis, Acker, och Heniford, 2008; Wallin, Meurling, Hedman, Hedengård, och Felländer-Tsai, 2007, som t ex att lära sig hur man avläser röntgenbilder (se t.ex. Söderström, Häll, Nilsson, och Ahlqvist 2012 eller till att lära hur man ska agera i komplexa situationer (Andersson, Carlström, och Berlin, 2013; Bauman, Gohm och Bonner, 2011, t.ex. vid svåra olyckshändelser med många personer inblandade (se t.ex. McConnell och Drennan, 2006. Simuleringar av komplexa situationer med många inblandade brukar benämnas som fullskaliga (se t.ex. Andersson, Carlström, och Berlin, 2013. Simuleringar antas träna och utveckla professionell kunskap genom att förbereda studenter på att hantera komplexa och ibland farliga situationer som de kan komma att ställas inför i en kommande yrkespraktik. Användningen av simuleringar i utbildningar bygger således på ett antagande om överföring av erfarenheter och kunskaper från ett sammanhang till ett annat (se t.ex.

    Alzheimer's disease copathology is common in PD at autopsy. In non-PD subjects with mild cognitive impairment, tau depositions can be detected using 18F-AV-1451 PET. We hypothesized that 18F-AV-1451 PET would show tau aggregation in PD with mild cognitive impairment and correlate with cognitive dysfunction. To describe tau aggregation in PD patients. Twenty-six PD patients and 23 controls had 18F-AV-1451 PET and neuropsychological assessment to detect mild cognitive impairment. Nine PD patients (35%) were identified with mild cognitive impairment. Regional analyses showed no significant differences between groups. Voxel-wise analyses showed no correlation with cognitive domain z-scores within patients. One patient with mild cognitive impairment was estimated Braak tau stage 5; all other patients were stage 0. Our results indicate that tau pathology, as detected by 18F-AV-1451, is uncommon in PD with mild cognitive impairment and shows no significant correlation with cognitive dysfunction at this stage. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    In risk assessment of aquatic sediments, much attention is paid to the difference between acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) as indicators of metal availability. Ten representative sampling sites were selected along the estuary of the Guadalete River. Surficial sediments were sampled in winter and summer to better understand SEM and AVS spatial and seasonal distributions and to establish priority risk areas. Total SEM concentration (SigmaSEM) ranged from 0.3 to 4.7 micromol g(-1). It was not significantly different between seasons, however, it showed a significant difference between sampling stations. AVS concentrations were much more variable, showing significant spatial and temporal variations. The values ranged from 0.8 to 22.4 micromol g(-1). The SEM/AVS ratio was found to be <1 at all except one station located near the mouth of the estuary. The results provided information on a potential pollution source near the mouth of the estuary, probably associated with vessel-related activities carried out in a local harbor area located near the station.

    Retinoic acid receptor-related orphan receptor-α (RORα) (NR1F1) is an orphan nuclear receptor with a potential role in metabolism. Previous studies have shown that RORα regulates transcription of the murine Apolipoprotein AI gene and human Apolipoprotein CIII genes. In the present study, we present evidence that RORα also induces transcription of the human Apolipoprotein AV gene, a recently identified apolipoprotein associated with triglyceride levels. Adenovirus-mediated overexpression of RORα increased the endogenous expression of ApoAV in HepG2 cells and RORα also enhanced the activity of an ApoAV promoter construct in transiently transfected HepG2 cells. Deletion and mutation studies identified three AGGTCA motifs in the ApoAV promoter that mediate RORα transactivation, one of which overlaps with a previously identified binding site for PPARα. Together, these results suggest a novel mechanism whereby RORα modulates lipid metabolism and implies RORα as a potential target for the treatment of dyslipidemia and atherosclerosis

    Acute excessive alcohol consumption is associated with heart rhythm disorders like atrial fibrillation but also premature ventricular contractions, collectively known as the "holiday heart syndrome". More rarely but clinically significant are reports of atrioventricular (AV) conduction disturbances in binge drinkers with no underlying heart disease or chronic alcohol consumption. To obtain better insights into common denominators and the potential underlying mechanisms we collected and compared individual case reports of AV block following acute alcohol intoxication in otherwise healthy people. By screening PubMed, Google Scholar, Scopus and JSTOR, fifteen cases were found of which eight were sufficiently documented for full analysis. Blood alcohol levels ranged from 90 to 958 mg/dl (19 to 205 mM). Second and third degree AV block was observed most (6/8) albeit that in two of these patients a vagal stimulus led to deterioration from first into higher order AV block. In all cases, patients reverted to normal sinus rhythm upon becoming sober again. Mildly lowered body temperature (35.9 ± 0.5°C) was observed but can be excluded as a major cause of conduction blockade. We hypothesize that ethanol induced partial inhibition of calcium and potentially also sodium currents in conductive tissue structures may be one of the mechanisms of conduction slowing and block that may become exaggerated upon increased vagal tone. An impairment of gap junction function cannot be excluded as a contributing factor. In conclusion, cases of documented alcohol induced AV block are very rare but events can occur at relatively low serum alcohol levels which should prompt to awareness of this phenomenon in alcohol intoxicated patients.

    Utilizing [18F]-AV-1451 tau positron emission tomography (PET) as an Alzheimer disease (AD) biomarker will require identification of brain regions that are most important in detecting elevated tau pathology in preclinical AD. Here, we utilized an unsupervised learning, data-driven approach to identify brain regions whose tau PET is most informative in discriminating low and high levels of [18F]-AV-1451 binding. 84 cognitively normal participants who had undergone AV-1451 PET imaging were used in a sparse k-means clustering with resampling analysis to identify the regions most informative in dividing a cognitively normal population into high tau and low tau groups. The highest-weighted FreeSurfer regions of interest (ROIs) separating these groups were the entorhinal cortex, amygdala, lateral occipital cortex, and inferior temporal cortex, and an average SUVR in these four ROIs was used as a summary metric for AV-1451 uptake. We propose an AV-1451 SUVR cut-off of 1.25 to define high tau as described by imaging. This spatial distribution of tau PET is a more widespread pattern than that predicted by pathological staging schemes. Our data-derived metric was validated first in this cognitively normal cohort by correlating with early measures of cognitive dysfunction, and with disease progression as measured by β-amyloid PET imaging. We additionally validated this summary metric in a cohort of 13 Alzheimer disease patients, and showed that this measure correlates with cognitive dysfunction and β-amyloid PET imaging in a diseased population.

    Full Text Available Hensikten med studiet var å belyse hvordan videodokumentasjon av praktiske handlinger i sykepleie kunne brukes som evalueringordning av studenter. Artikkelen tar utgangspunkt i et forskningsprosjekt for utprøving av nye lærings og evalueringsformer i bachelorutdanningen i sykepleie, der 13 studentgrupper gjennomførte sin praktiske eksamen ved innlevering av video av 16 utvalgte øvelser. Tradisjonell praktisk eksamen i samme studentkull ble gjennomført for 10 studentgrupper. Prosjektet er en kvalitativ kasusstudie og analyse er gjort etter inspirasjon av Giorgi‘s empiriske fenomenologi. Diskusjonen tar utgangspunkt i Vygotsky‘s sosiokulturelle syn på læring og Dewey‘s prinsipp om at all læring er basert på erfaring. Funnene er presentert i følgende deler: Første del omhandler videodokumentasjon og refleksjon. De to neste delene viser funn i forhold til mesterlæring og situert læring på vei mot forståelse av hva sykepleie er. Deretter er teknisk utfordringer belyst, og til slutt en drøfting av forhold ved oppøving av praktiske sykepleieferdigheter. Konklusjonen her er at video egner seg til å dokumentere sykepleiehandlinger. Dette har størst verdi for læring og refleksjon, i mindre grad som eksamensform.

    Defensins are frontline peptides of mucosal immunity in the animal kingdom, including birds. Their resistance to proteolysis and their ensuing ability to maintain antimicrobial potential remains questionable and was therefore investigated. We have shown by bottom-up mass spectrometry analysis of protein extracts that both avian beta-defensins AvBD2 and AvBD7 were ubiquitously distributed along the chicken gut. Cathepsin B was found by immunoblotting in jejunum, ileum, caecum, and caecal tonsils, while cathepsins K, L, and S were merely identified in caecal tonsils. Hydrolysis product of AvBD2 and AvBD7 incubated with a panel of proteases was analysed by RP-HPLC, mass spectrometry and antimicrobial assays. AvBD2 and AvBD7 were resistant to serine proteases and to cathepsins D and H. Conversely cysteine cathepsins B, K, L, and S degraded AvBD2 and abolished its antibacterial activity. Only cathepsin K cleaved AvBD7 and released Ile4-AvBD7, a N-terminal truncated natural peptidoform of AvBD7 that displayed antibacterial activity. Besides the 3-stranded antiparallel beta-sheet typical of beta-defensins, structural analysis of AvBD7 by two-dimensional NMR spectroscopy highlighted the restricted accessibility of the C-terminus embedded by the N-terminal region and gave a formal evidence of a salt bridge (Asp9-Arg12) that could account for proteolysis resistance. The differential susceptibility of avian defensins to proteolysis opens intriguing questions about a distinctive role in the mucosal immunity against pathogen invasion.

    We examined the relationship between in vivo estimates of tau deposition as measured by 18 F-AV-1451 tau positron emission tomography imaging and cross-sectional cortical thickness, as well as rates of antecedent cortical thinning measured from magnetic resonance imaging in individuals with and without evidence of cerebral amyloid in 63 participants from the Alzheimer's Disease Neuroimaging Initiative study, including 32 cognitively normal individuals (mean age 74 years), 27 patients with mild cognitive impairment (mean age 76.8 years), and 4 patients diagnosed with Alzheimer's disease (mean age 80 years). We hypothesized that structural measures would correlate with 18 F-AV-1451 in a spatially local manner and that this correlation would be stronger for longitudinal compared to cross-sectional measures of cortical thickness and in those with cerebral amyloid versus those without. Cross-sectional and longitudinal estimates of voxelwise atrophy were made from whole brain maps of cortical thickness and rates of thickness change. In amyloid-β-positive individuals, the correlation of voxelwise atrophy across the whole brain with a summary measure of medial temporal lobe (MTL) 18 F-AV-1451 uptake demonstrated strong local correlations in the MTL with longitudinal atrophy that was weaker in cross-sectional analysis. Similar effects were seen in correlations between 31 bilateral cortical regions of interest. In addition, several nonlocal correlations between atrophy and 18 F-AV-1451 uptake were observed, including association between MTL atrophy and 18 F-AV-1451 uptake in parietal lobe regions of interest such as the precuneus. Amyloid-β-negative individuals only showed weaker correlations in data uncorrected for multiple comparisons. While these data replicate previous reports of associations between 18 F-AV-1451 uptake and cross-sectional structural measures, the current results demonstrate a strong relationship with longitudinal measures of atrophy. These data

    The tau tangle ligand (18)F-AV-1451 ((18)F-T807) binds to neuromelanin in the midbrain, and may therefore be a measure of the pigmented dopaminergic neuronal count in the substantia nigra. Parkinson's disease is characterized by progressive loss of dopaminergic neurons. Extrapolation of post-mortem data predicts that a ∼30% decline of nigral dopamine neurons is necessary to cause motor symptoms in Parkinson's disease. Putamen dopamine terminal loss at disease onset most likely exceeds that of the nigral cell bodies and has been estimated to be of the order of 50-70%. We investigated the utility of (18)F-AV-1451 positron emission tomography to visualize the concentration of nigral neuromelanin in Parkinson's disease and correlated the findings to dopamine transporter density, measured by (123)I-FP-CIT single photon emission computed tomography. A total of 17 patients with idiopathic Parkinson's disease and 16 age- and sex-matched control subjects had (18)F-AV-1451 positron emission tomography using a Siemens high-resolution research tomograph. Twelve patients with Parkinson's disease also received a standardized (123)I-FP-CIT single photon emission computed tomography scan at our imaging facility. Many of the patients with Parkinson's disease displayed visually apparent decreased (18)F-AV-1451 signal in the midbrain. On quantitation, patients showed a 30% mean decrease in total nigral (18)F-AV-1451 volume of distribution compared with controls (P = 0.004), but there was an overlap of the individual ranges. We saw no significant correlation between symptom dominant side and contralateral nigral volume of distribution. There was no correlation between nigral (18)F-AV-1451 volume of distribution and age or time since diagnosis. In the subset of 12 patients, who also had a (123)I-FP-CIT scan, the mean total striatal dopamine transporter signal was decreased by 45% and the mean total (18)F-AV-1451 substantia nigra volume of distribution was decreased by 33% after

    Lönsamheten för konsultbolag är beroende av antalet timmar konsulter arbetar vad gäller leveranser i kunduppdrag. Att timmar ej levereras på grund av sjukdom eller överbeläggning påverkar resultatet för bolaget. Konsultbolag där konsulter samma vecka arbetar mot olika kunder och uppdrag, kan ha svårt att synliggöra och följa upp leveranserna vilket kan resultera i inkomstbortfall och försenade leveranser.

  19. Språkkartlegging av flerspråklige barn i barnehagen - fra kontrovers til kompromiss?

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available Språkkartlegging i barnehagen er et konfliktfylt felt som preges av enten/eller tenkning. På den ene siden ser kartleggingstilhengerne ut til å ha en positivistisk tro på at kartlegging kan bidra til løsninger på alt fra enkeltbarns behov for hjelp, til tilrettelegging for livslang læring og sosial utjevning. På den andre siden ser kartleggingsskeptikerne ut til å befinne seg innenfor den nordiske barnehagemodellen, som tradisjonelt bygger på et helhetlig syn på læring og på en sterk vektlegging av barndommens egenverdi. Spenningen kan ha store konsekvenser for praksisfeltet. I denne artikkelen drøfter jeg språkkartleggingsdiskursen i lys av teori om vitenskapelige kontroverser og konkluderer med at det er åpning for kompromisser, men også at det er tendenser i diskursen som snarere kan forsterke enn redusere uenigheten om språkkartlegging av flerspråklige barn i barnehagen. Mapping of language skills in early childhood education and care (ECEC institutions is controversial. On the one hand, there are those who support language mapping based on a belief that mapping and measuring can help language acquisition and facilitate lifelong learning and social integration. On the other hand, there are skeptics who oppose mapping and emphasize the values of childhood. This article discusses the discourses on language mapping in light of theories on scientific controversies. Based on the analysis I find that although there are openings for compromises, it seems that tendencies in the discourse may amplify rather than reduce the controversy on the language mapping of multilingual children in Norwegian ECEC institutions.

    2017-09-01

    This paper compares the coding efficiency performance on 360 videos, of three software codecs: (a) AV1 video codec from the Alliance for Open Media (AOM); (b) the HEVC Reference Software HM; and (c) the JVET JEM Reference SW. Note that 360 video is especially challenging content, in that one codes full res globally, but typically looks locally (in a viewport), which magnifies errors. These are tested in two different projection formats ERP and RSP, to check consistency. Performance is tabulated for 1-pass encoding on two fronts: (1) objective performance based on end-to-end (E2E) metrics such as SPSNR-NN, and WS-PSNR, currently developed in the JVET committee; and (2) informal subjective assessment of static viewports. Constant quality encoding is performed with all the three codecs for an unbiased comparison of the core coding tools. Our general conclusion is that under constant quality coding, AV1 underperforms HEVC, which underperforms JVET. We also test with rate control, where AV1 currently underperforms the open source X265 HEVC codec. Objective and visual evidence is provided.

  4. Characterisation of human AV-nodal properties using a network model.

    2018-02-01

    Characterisation of the AV-node is an important step in determining the optimal form of treatment for supraventricular tachycardias. To integrate and analyse patient-specific measurements, mathematical modelling has emerged as a valuable tool. Here we present a model of the human AV-node, consisting of a series of interacting nodes, each with separate dynamics in refractory time and conduction delay. The model is evaluated in several scenarios, including atrial fibrillation (AF) and clinical pacing, using simulated and measured data. The model is able to replicate signals derived from clinical ECG data as well as from invasive measurements, both under AF and pacing. To quantify the uncertainty in parameter estimation, 1000 parameter sets were sampled, showing that model output similar to data corresponds to limited regions in the model parameter space. The model is the first human AV-node model to capture both spatial and temporal dynamics while being efficient enough to allow interactive use on clinical timescales, as well as parameter estimation and uncertainty quantification. As such, it fills a new niche in the current set of published models and forms a valuable tool for both understanding and clinical research.

    Directory of Open Access Journals (Sweden)

    Natascha Reinhoff

    2002-08-01

    Full Text Available Når det gjelder romanen Naustet av Jon Fosse er det ikke tvil om at det blant annet – og kanskje hovedsaklig – er „dette noko / skrifta berettar om“. Det er derfor denne romanen også kan kalles for en metaroman. Tematiseringen av skriveren og skriveprosessen i romanen tar ikke bare mye plass på historienivå: Den gjennomsyrer romanen. Nært forbundet med denne tematikken er et fenomen jeg ville kalle for „dobbeltperspektivet i romanen“, og det er dette jeg vil se litt nærmere på her. Selv om romanen Naustet – i god postmoderne tradisjon – i siste – og kanskje allerede i første – instans unndrar seg en fast og entydig tilskrivning av betydning – og slik bevarer sin magi – skal jeg prøve å nærme meg skriveren og dobbeltperspektivet „eit stykke på veg“. Men først et par ord om begrepet skriver.

    Objective Phenylketonuria is an inherited disease caused by impaired activity of phenylalanine hydroxylase, the enzyme that converts phenylalanine to tyrosine, leading to accumulation of phenylalanine and subsequent neurocognitive dysfunction. A phenylalanine-restricted diet initiated early in life can ameliorate the toxic effects of phenylalanine. However, the diet is onerous and compliance is extremely difficult. Phenylalanine ammonia lyase (PAL) is a prokaryotic enzyme that converts phenylalanine to ammonia and trans-cinnamic acid. This Phase 1, multicenter clinical trial evaluated the safety, tolerability, pharmacokinetics and efficacy of rAvPAL-PEG (recombinant Anabaena variabilis PAL produced in E. coli conjugated with polyethylene glycol [PEG] to reduce immunogenicity) in reducing phenylalanine levels in subjects with phenylketonuria. Methods Single subcutaneous injections of rAvPAL-PEG in escalating doses (0·001, 0·003, 0·01, 0·03, and 0·1 mg/kg) were administered to 25 adults with phenylketonuria recruited from those attending metabolic clinics in North America whose blood phenylalanine concentrations were ≥600 μmol/L. Results The most frequently reported adverse events were injection-site reactions and dizziness. Reactions were self-limited without sequelae. During the trial, two subjects had adverse reactions to intramuscular (IM) medroxyprogesterone acetate, a drug containing polyethylene glycol as an excipient. Three subjects developed a generalized skin rash at the highest rAvPAL-PEG dose (0·1 mg/kg). Drug levels peaked ∼5 days after the injection. Treatment was effective in reducing blood phenylalanine in all five subjects receiving the highest dose (0·1 mg/kg, mean percent change of -58 from baseline), with a nadir ∼6 days after injection and inverse correlation between drug and phenylalanine concentrations in plasma. Phenylalanine concentrations returned to near-baseline levels ∼20 days after the single injection. Conclusions

    The study assessed the hydroalcohol extract effects of Crocus sativus L. (saffron) on (i) the basic and rate-dependent electrophysiological properties of the AV node, (ii) remodeling of the AV node during experimental atrial fibrillation (AF) and (iii) the role of nitric oxide (NO) in the effects of saffron on the AV node. Stimulation protocols in isolated AV node were used to quantify AV nodal recovery, facilitation and fatigue in four groups of rabbits (n = 8-16 per group). In addition, the nodal response to AF was evaluated at multiple cycle lengths and during AF. Saffron had a depressant effect on AV nodal rate-dependent properties; further, it increased Wenckebach block cycle length, functional refractory period, facilitation and fatigue (p AV node (p AV node during AF by saffron. Saffron increased the AV nodal refractoriness and zone of concealment. These depressant effects of saffron were mediated by endogenous NO. Copyright © 2011 John Wiley & Sons, Ltd.

    The EVOCAV(DS) trial aimed to quantify the paradoxal atrioventricular (AV) conduction time lengthening in sinus node (SD) patients (pts) paced in AAIR-based pacing mode. SD pts, implanted with dual-chamber pacemaker programmed in AAIR-based pacing mode, were randomized in two arms for a 1-month period: the low atrial pacing (LAP; basic rate at 60 bpm, dual sensor with minimal slope) and the high atrial pacing (HAP; basic rate at 70 bpm, dual sensor with optimized slope, overdrive pacing) arm. At 1 month, crossover was performed for an additional 1-month period. AV conduction time, AV block occurrence and AV conduction time adaptation during exercise were ascertained from device memories at each follow-up. Seventy-nine pts participated to the analysis (75 ± 8 years; 32 male; PR = 184 ± 38 ms; bundle branch block n = 12; AF history n = 36; antiarrhythmic treatment n = 53; beta-blockers n = 27; class III/Ic n = 18; both n = 8). The mean AV conduction time was significantly greater during the HAP (275 ± 51 ms) vs. LAP (263 ± 49 ms) period (p AV blocks occurred in 49 % of pts in the HAP vs. 19 % in the LAP period (p AV conduction time during exercise. AAIR-based pacing in SD pts may induce a significant lengthening of pts' AV conduction time, including frequent abnormal adaptation of AV conduction time during exercise.

    To examine region- and substrate-specific autoradiographic and in vitro binding patterns of positron emission tomography tracer [F-18]-AV-1451 (previously known as T807), tailored to allow in vivo detection of paired helical filament-tau-containing lesions, and to determine whether there is off-target binding to other amyloid/non-amyloid proteins. We applied [F-18]-AV-1451 phosphor screen autoradiography, [F-18]-AV-1451 nuclear emulsion autoradiography, and [H-3]-AV-1451 in vitro binding assays to the study of postmortem samples from patients with a definite pathological diagnosis of Alzheimer disease, frontotemporal lobar degeneration-tau, frontotemporal lobar degeneration-transactive response DNA binding protein 43 (TDP-43), progressive supranuclear palsy, corticobasal degeneration, dementia with Lewy bodies, multiple system atrophy, cerebral amyloid angiopathy and elderly controls free of pathology. Our data suggest that [F-18]-AV-1451 strongly binds to tau lesions primarily made of paired helical filaments in Alzheimer brains (eg, intraneuronal and extraneuronal tangles and dystrophic neurites), but does not seem to bind to a significant extent to neuronal and glial inclusions mainly composed of straight tau filaments in non-Alzheimer tauopathy brains or to lesions containing β-amyloid, α-synuclein, or TDP-43. [F-18]-AV-1451 off-target binding to neuromelanin- and melanin-containing cells and, to a lesser extent, to brain hemorrhagic lesions was identified. Our data suggest that [F-18]-AV-1451 holds promise as a surrogate marker for the detection of brain tau pathology in the form of tangles and paired helical filament-tau-containing neurites in Alzheimer brains but also point to its relatively lower affinity for lesions primarily made of straight tau filaments in non-Alzheimer tauopathy cases and to the existence of some [F-18]-AV-1451 off-target binding. These findings provide important insights for interpreting in vivo patterns of [F-18]-AV-1451 retention

    Lilly/Avid's AV-1451 is one of the most advanced tau PET tracers in the clinic. Although results obtained in Alzheimer's disease patients are compelling, discrimination of tracer uptake in healthy individuals and patients with supranuclear palsy (PSP) is less clear as there is substantial overlap of signal in multiple brain regions. Moreover, accurate quantification of [ 18 F]AV-1451 uptake in Alzheimer's disease may not be possible. The aim of the present study was to characterize the in vitro binding of AV-1451 to understand and identify potential off-target binding that could explain the poor discrimination observed in PSP patients. [ 3 H]AV-1451 and AV-1451 were characterized in in vitro binding assays using recombinant and native proteins/tissues from postmortem samples of controls and Alzheimer's disease and PSP patients. [ 3 H]AV-1451 binds to multiple sites with nanomolar affinities in brain homogenates and to tau fibrils isolated from Alzheimer's disease or PSP patients. [ 3 H]AV-1451 also binds with similarly high affinities in brain homogenates devoid of tau pathology. This unexpected binding was demonstrated to be because of nanomolar affinities of [ 3 H]AV-1451 for monoamine oxidase A and B enzymes. High affinity of AV-1451 for monoamine oxidase proteins may limit its utility as a tau PET tracer in PSP and Alzheimer's disease because of high levels of monoamine oxidase expression in brain regions also affected by tau deposition, especially if monoamine oxidase levels change over time or with a treatment intervention. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

    Cerebral glucose metabolism measured with [18F]-FDG PET is a well established marker of neuronal dysfunction in neurodegeneration. The tau-protein tracer [18F]-AV-1451 PET is currently under evaluation and shows promising results. Here, we assess the feasibility of early perfusion imaging with AV-1451 as a substite for FDG PET in assessing neuronal injury. Twenty patients with suspected neurodegeneration underwent FDG and early phase AV-1451 PET imaging. Ten one-minute timeframes were acquired after application of 200 MBq AV-1451. FDG images were acquired on a different date according to clinical protocol. Early AV-1451 timeframes were coregistered to individual FDG-scans and spatially normalized. Voxel-wise intermodal correlations were calculated on within-subject level for every possible time window. The window with highest pooled correlation was considered optimal. Z-transformed deviation maps (ZMs) were created from both FDG and early AV-1451 images, comparing against FDG images of healthy controls. Regional patterns and extent of perfusion deficits were highly comparable to metabolic deficits. Best results were observed in a time window from 60 to 360 s (r = 0.86). Correlation strength ranged from r = 0.96 (subcortical gray matter) to 0.83 (frontal lobe) in regional analysis. ZMs of early AV-1451 and FDG images were highly similar. Perfusion imaging with AV-1451 is a valid biomarker for assessment of neuronal dysfunction in neurodegenerative diseases. Radiation exposure and complexity of the diagnostic workup could be reduced significantly by routine acquisition of early AV-1451 images, sparing additional FDG PET.

    The mechanoenergetic effects of atrioventricular delay optimization during biventricular pacing ("cardiac resynchronization therapy", CRT) are unknown. Eleven patients with heart failure and left bundle branch block (LBBB) underwent invasive measurements of left ventricular (LV) developed pressure, aortic flow velocity-time-integral (VTI) and myocardial oxygen consumption (MVO2) at 4 pacing states: biventricular pacing (with VV 0 ms) at AVD 40 ms (AV-40), AVD 120 ms (AV-120, a common nominal AV delay), at their pre-identified individualised haemodynamic optimum (AV-Opt); and intrinsic conduction (LBBB). AV-120, relative to LBBB, increased LV developed pressure by a mean of 11(SEM 2)%, p=0.001, and aortic VTI by 11(SEM 3)%, p=0.002, but also increased MVO2 by 11(SEM 5)%, p=0.04. AV-Opt further increased LV developed pressure by a mean of 2(SEM 1)%, p=0.035 and aortic VTI by 4(SEM 1)%, p=0.017. MVO2 trended further up by 7(SEM 5)%, p=0.22. Mechanoenergetics at AV-40 were no different from LBBB. The 4 states lay on a straight line for Δexternal work (ΔLV developed pressure × Δaortic VTI) against ΔMVO2, with slope 1.80, significantly >1 (p=0.02). Biventricular pacing and atrioventricular delay optimization increased external cardiac work done but also myocardial oxygen consumption. Nevertheless, the increase in cardiac work was ~80% greater than the increase in oxygen consumption, signifying an improvement in cardiac mechanoenergetics. Finally, the incremental effect of optimization on external work was approximately one-third beyond that of nominal AV pacing, along the same favourable efficiency trajectory, suggesting that AV delay dominates the biventricular pacing effect - which may therefore not be mainly "resynchronization". © 2013.

  15. Norwegian resource policy: The production rate for Norwegian petroleum resources; Norsk ressurspolitikk: Utvinningstempoet for norske petroleumsressurser

    Energy Technology Data Exchange (ETDEWEB)

    Schreiner, P.

    1995-12-31

    Petroleum activities have become a large industry in Norway. This has led to extensive changes in Norwegian economy and society. In the public debate on this activity there has been little discussion of what would be the most profitable production rate. However, it is generally agreed that the great wealth implied by the petroleum resources must be managed in ways suitable to both present and coming generations. This report discusses the production rate based on the following questions: (1) How high can the production rate be before the petroleum activities and the expenditure of the income from them influence the remaining Norwegian economy too strongly? (2) How much of this wealth should reasonably be used by present generations and how much should be left for future generations? There is much to gain from a high tempo and from relocating some of the petroleum wealth. The possibilities of influencing the production rate are mainly connected with the allotments of production licences. The consequences of uncertainties in the petroleum activities for the choice of exploitation tempo are unclear. The environment is not much affected by the production rate. The contractor activity has become Norway`s largest industry. 42 refs., 14 figs., 2 tabs.

    9-[(18)F]Fluoropropyl-(+)-dihydrotetrabenazine ([(18)F]AV-133) is a new PET imaging agent targeting vesicular monoamine transporter type II (VMAT2). To shorten the preparation of [(18)F]AV-133 and to make it more widely available, a simple and rapid purification method using solid-phase extraction (SPE) instead of high-pressure liquid chromatography (HPLC) was developed. The SPE method produced doses containing the non-radioactive pseudo-carrier 9-hydroxypropyl-(+)-dihydrotetrabenazine (AV-149). The objectives of this study were to evaluate the brain uptake of AV-149 by UPLC-MS/MS and its effect on the biodistribution of [(18)F]AV-133 in the brains of mice. The mice were injected with a bolus including [(18)F]AV-133 and different doses of AV-149. Brain tissue and blood samples were harvested. The effect of different amounts of AV-149 on [(18)F]AV-133 was evaluated by quantifying the brain distribution of radiolabelled tracer [(18)F]AV-133. The concentrations of AV-149 in the brain and plasma were analyzed using a UPLC-MS/MS method. The concentrations of AV-149 in the brain and plasma exhibited a good linear relationship with the doses. The receptor occupancy curve was fit, and the calculated ED50 value was 8.165mg/kg. The brain biodistribution and regional selectivity of [(18)F]AV-133 had no obvious differences at AV-149 doses lower than 0.1mg/kg. With increasing doses of AV-149, the brain biodistribution of [(18)F]AV-133 changed significantly. The results are important to further support that the improved radiolabelling procedure of [(18)F]AV-133 using an SPE method may be suitable for routine clinical application.

    AV nodal reentrant tachycardia (AVNRT) is commonly encountered in pediatric patients. Definite treatment can be achieved by catheter ablation. The purpose of the study was to evaluate the efficacy and safety of AVNRT ablation focusing on children with a body weight ≤25 kg. Catheter ablation of AVNRT was attempted in 253 patients. Median age was 12.5 years; median body weight was 48.7 kg. 25 (9.9 %) children had a body weight ≤25 kg. Congenital heart disease was present in 6 patients (2.4 %). Procedural success was achieved in 98 % using radiofrequency, in 100 % using cryoenergy alone, and in 94 % using both energy sources. In patients with a body weight ≤25 kg, success was achieved in 96 %. In patients ≤25 kg, fluoroscopy and procedure duration did not differ from those >25 kg. The rate of major complications was significantly higher in the patients ≤25 kg (12 vs. 2.2 %, p = 0.04). Permanent AV block after RF ablation occurred in 2 patients with congenital heart disease and one infant with a body weight of 8.7 kg. Catheter ablation of AVNRT in children and adolescents was safe and effective. Infants and small children with a body weight ≤25 kg had a higher prevalence of serious complications. This should alert physicians in decision making toward catheter ablation in these patients. In patients with congenital heart disease and different anatomy of the cardiac conduction system, operators must be aware of an increased risk for AV block.

    Apraxia of speech is a motor speech disorder characterized by combinations of slow speaking rate, abnormal prosody, distorted sound substitutions, and trial-and-error articulatory movements. Apraxia of speech is due to abnormal planning and/or programming of speech production. It is referred to as primary progressive apraxia of speech (PPAOS) when it is the only symptom of a neurodegenerative condition. Past reports suggest an association of PPAOS with primary 4-repeat (4R) tau (e.g., progressive supranuclear palsy, corticobasal degeneration), rather than amyloid, pathology. The goal of the current study was to investigate the distribution of tau tracer uptake using [18F]AV-1451 positron emission tomography (PET) imaging in patients with PPAOS. Fourteen PPAOS patients underwent [18F]AV-1451 PET (tau-PET) imaging, [C11] Pittsburgh Compound B (PiB) PET and structural MRI and were matched 3:1 by age and sex to 42 cognitively normal controls. Tau-PET uptake was assessed at the region-of-interest (ROI) level and at the voxel-level. The PPAOS group (n = 14) showed increased tau-PET uptake in the precentral gyrus, supplementary motor area and Broca's area compared to controls. To examine whether tau deposition in Broca's area was related to the presence of aphasia, we examined a subgroup of the PPAOS patients who had predominant apraxia of speech, with concomitant aphasia (PPAOSa; n = 7). The PPAOSa patients showed tau-PET uptake in the same regions as the whole group. However, the remaining seven patients who did not have aphasia showed uptake only in superior premotor and precentral cortices, with no uptake observed in Broca's area. This cross-sectional study demonstrates that elevated tau tracer uptake is observed using [18F]AV-1451 in PPAOS. Further, it appears that [18F]AV-1451 is sensitive to the regional distribution of tau deposition in different stages of PPAOS, given the relationship between tau signal in Broca's area and the presence of aphasia.

    2014-05-01

    Cor triatriatum dexter (CTD) is an extremely rare cardiac anomaly in which the right atrium is divided into two distinct chambers by a membrane. The persistence of the right valve of sinus venosus results in a complete septation of the right atrium. This anomaly is frequently associated with other right-sided cardiac abnormalities. Its clinical manifestation and the need for intervention are determined by the number and the size of the fenestrations on the membrane, associated cardiac anomalies and arrhythmias. We describe a case of CTD in a patient with complete atrioventricular (A-V) block.

    Full Text Available Artikkelen tar for seg språkhistorie som norskdidaktisk emne i et faghistorisk perspektiv. På grunnlag av en lang rekke styringsdokumenter (læreplaner og studieplaner og fagdidaktisk og disiplinfaglig litteratur undersøkes hvordan språkets historiske dimensjoner har blitt tematisert som kunnskapsområde. Et hovedfunn i denne gjennomgangen er at det historiske (eller historiserende lengdesnittet har vært til stede gjennom hele 1900-tallet og fortsatt finnes i gjeldende læreplan – om enn med temmelig varierende vektlegging og detaljering. Læreplanene har i stor grad overlatt til praktikerne (lærerne og lærerutdannerne å avgrense hva de språkhistoriske emnene skal romme. Litteraturanalysen viser videre at den didaktiske refleksjonen på dette feltet bare unntaksvis har kommet på trykk, og denne begrensete språkhistorie-didaktiske debatten må forstås på bakgrunn av tilstanden i forsknings- og studiefaget.Nøkkelord: språkhistorie-didaktikk, språkdidaktikk, språkhistorie, norskdidaktikkAbstractThis article deals with language history as a didactic topic in the subject Norwegian as L1. On the basis of a wide range of documents (curricula and syllabi and didactic and disciplinary literature, the article seeks to examine how the historical dimensions of language have been treated as an area of knowledge. A main finding is that the historic (or historicizing perspective has been present through the entire 20th century and still can be found in the current curriculum – though the emphasis and itemization have varied significantly. The curricula have largely entrusted the practicians (the teachers and teacher educators with the powers to delineate the language history topics. The research review further shows that the didactic reflections within this field only sporadically have appeared in print, and this limited didactic discussion of language history must be understood on the background of the condition of the discipline

    Corticobasal syndrome (CBS) is a phenotypic manifestation of diverse pathologies, including Alzheimer's disease and 4-repeat tauopathies. Predicting pathology in CBS is unreliable and, hence, molecular neuroimaging may prove to be useful. The aim of this study was to assess regional patterns of uptake on [ 18 F] AV-1451 PET in CBS and determine whether patterns of uptake differ according to beta-amyloid deposition or differing clinical presentations. Fourteen patients meeting criteria for CBS underwent Pittsburgh Compound B (PiB) and [ 18 F] AV-1451 PET. Seven patients presented as CBS and seven presented with apraxia of speech (AOS) and later evolved into CBS. A global PiB summary was calculated and used to classify patients as PiB (-) or PiB (+). AV-1451 uptake was calculated in fourteen regions-of-interest, with values divided by uptake in cerebellar crus grey matter to generate standard uptake value ratios. AV-1451 uptake was considered elevated if it fell above the 95th percentile from a group of 476 cognitively unimpaired normal controls. Six of the 14 CBS patients (43%) were PiB (+), with three of these patients showing strikingly elevated AV-1451 uptake across many cortical regions. Of the eight PiB (-) patients, only those with AOS showed elevated AV-1451 uptake in supplementary motor area and precentral cortex compared to controls. No region of elevated AV-1451 uptake were observed in PiB (-) typical CBS patients without AOS. These results suggest that regional [ 18 F] AV-1451 is variable in CBS and depends on the presence of beta-amyloid as well as clinical presentation such as AOS. PiB (+) CBS does not necessarily reflect underlying Alzheimer's disease; however, the possibility some of these patients will evolve into Alzheimer's disease over time cannot be excluded.

  20. AV3V lesions attenuate the cardiovascular responses produced by blood-borne excitatory amino acid analogs

    Systemic injections of the excitatory amino acid (EAA) analogs, kainic acid (KA) and N-methyl-D-aspartate (NMDA), produce a pressor response in conscious rats that is caused by a centrally mediated activation of sympathetic drive and the release of arginine vasopressin (AVP). This study tested the hypothesis that the tissue surrounding the anteroventral part of the third ventricle (AV3V) plays a role in the expression of the pressor responses produced by systemically injected EAA analogs. Specifically, we examined whether prior electrolytic ablation of the AV3V region would affect the pressor responses to KA and NMDA (1 mg/kg iv) in conscious rats. The KA-induced pressor response was smaller in AV3V-lesioned than in sham-lesioned rats (11 +/- 2 vs. 29 +/- 2 mmHg; P response in sham-lesioned but not AV3V-lesioned rats (+27 +/- 3 vs. +1 +/- 2 mmHg; P response in ganglion-blocked sham-lesioned rats was abolished by a vasopressin V1-receptor antagonist. Similar results were obtained with NMDA. The pressor response to AVP (10 ng/kg iv) was slightly smaller in AV3V-lesioned than in sham-lesioned ganglion-blocked rats (45 +/- 3 vs. 57 +/- 4 mmHg; P responses to systemically injected EAA analogs are smaller in AV3V-lesioned rats. The EAA analogs may produce pressor responses by stimulation of EAA receptors in the AV3V region, or the AV3V region may play an important role in the expression of these responses.

    Advanced Vitrification System (AVS) is commissioned for vitrification of high level waste (HLW) by using Joule heated ceramic melter first time in India. The HLW is generated in fuel reprocessing plant. For radiological surveillance of plant, Health Physics Unit (HPU) had installed 37 Area Gamma Monitors (AGM), 7 Continuous Air Monitors (CAM) and all types of personal contamination monitors. Exposure control is a major concern in operating plant. Therefore in addition to installed monitors, we have developed online remote radiation monitoring system to minimize exposures to the surveyor and operator. This also helped in volume reduction of secondary waste. The reliability and accuracy of the online monitoring system is confirmed by calibrating the system by comparing TLD and DRD readings and by theoretical analysis. In addition some modifications were carried in HP instruments to make them user friendly. This paper summarizes different kinds of remote radiological monitoring systems installed for online monitoring of Melter off Gas (MOG) filter, Hood filter, three exhaust filter banks, annulus air sampling and over pack monitoring in AVS. Our online remote monitoring system has helped the plant management to plan in advance for replacement of these filters, which resulted in considerable saving of collective dose. (author)

    Slow pathway modification (SPM) is the therapy of choice for AV-nodal reentry tachycardia (AVNRT). When AVNRT is not inducible, empirical ablation can be considered, however, the outcome in patients with two AV nodal echo beats (AVNEBs) is unknown. Out of a population of 3003 patients who underwent slow pathway modification at our institution between 1993 and 2013, we retrospectively included 32 patients with a history of symptomatic tachycardia, lack of paroxysmal supraventricular tachycardia (pSVT) inducibility but occurrence of two AVNEBs. pSVT documentation by electrocardiography (ECG) was present in 20 patients. The procedural endpoint was inducibility of less than two AVNEBs. This was reached in 31 (97%) patients. Long-term success was assessed by a telephone questionnaire (follow-up time 63±9 months). A total 94% of the patients benefited from the procedure (59% freedom from symptoms; 34% improvement in symptoms). Among those patients in whom ECG documentation was not present, 100% benefited (58% freedom from symptoms, 42% improvement). This is the first collective analysis of a group of patients presenting with symptoms of pSVT and inducibility of only two AVNEBs. Procedural success and clinical long-term follow-up were in the range of the reported success rates of slow pathway modification of inducible AVNRT, independent of whether ECG documentation was present. Thus, SPM is a safe and effective therapy in patients with two AVNEBs. Copyright © 2016. Published by Elsevier Ltd.

    A prospective randomized trial was set up to evaluate contractile parameters and quality of life in patients with congestive heart failure. We describe the results from 38 patients in sinus rhythm and with chronic heart failure due to congestive cardiomyopathy, prospectively randomized to optimal medical therapy (Group 1, 19 patients) or optimal medical therapy plus dual chamber pacemaker programmed to optimal AV delay (Group 2, 19 patients). At a 6 month follow-up, 7/19 patients in Group 1 had died compared with 5/19 patients in Group 2. During follow-up, there were few significant changes in evaluated parameters except for mitral regurgitation time, which was prolonged in Group 1 and shortened in Group 2. The systolic left ventricular diameter shortened significantly only in Group 2. An energy and activity questionnaire showed that the effect of DDD pacing in the latter patient population was beneficial. From these results we may conclude that at the 6 month follow-up DDD pacing with echo-optimized AV interval programming can improve quality of life without affecting survival.

    Google started the WebM Project in 2010 to develop open source, royalty- free video codecs designed specifically for media on the Web. The second generation codec released by the WebM project, VP9, is currently served by YouTube, and enjoys billions of views per day. Realizing the need for even greater compression efficiency to cope with the growing demand for video on the web, the WebM team embarked on an ambitious project to develop a next edition codec AV1, in a consortium of major tech companies called the Alliance for Open Media, that achieves at least a generational improvement in coding efficiency over VP9. In this paper, we focus primarily on new tools in AV1 that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked. Specifically, we describe tools and coding modes that improve intra, inter and combined inter-intra prediction. Results are presented on standard test sets.

    In order to establish defined viruses for challenging plants in resistance breeding programmes, Indian cassava mosaic virus (ICMV; family Geminiviridae) DNA clones were modified to monitor viral spread in plants by replacing the coat protein gene with the green fluorescent protein (GFP) reporter gene. Comparative in situ hybridization experiments showed that ICMV was restricted to the phloem in cassava and tobacco. GFP-tagged virus spread similarly, resulting in homogeneous fluorescence within nuclei and cytoplasm of infected cells. To analyze viral intercellular transport in further detail, GFP was fused to AV2, a protein that has been implicated in viral movement. Expressed from replicating viruses or from plasmids, AV2:GFP became associated with the cell periphery in punctate spots, formed cytoplasmic as well as nuclear inclusion bodies, the latter as conspicuous paired globules. Upon particle bombardment of expression plasmids, AV2:GFP was transported into neighboring cells of epidermal tissues showing that the intercellular transport of the AV2 protein is not restricted to the phloem. The results are consistent with a redundant function of ICMV AV2 acting as a movement protein, presumably as an evolutionary relic of a monopartite geminivirus that may still increase virus fitness but is no longer necessary in a bipartite genome. The fusion of ICMV ORF AV2 to the GFP gene is the first example of a reporter construct that follows the whole track of viral DNA from inside the nucleus to the cell periphery and to the next cell

    A cryptic prokaryotic promoter, designated AV3 promoter, has been previously identified in certain begomovirus genus, including ageratum yellow vein virus isolate NT (AYVV-NT). In this study, we demonstrated that the core nucleotides in the putative -10 and -35 boxes are necessary but not sufficient for promoter activity in Escherichia coli, and showed that AYVV-NT AV3 promoter could specifically interact with single-stranded DNA-binding protein and sigma 70 of E. coli involved in transcription. Several AYVV-NT-encoded proteins were found to increase the activity of AV3 promoter. The transcription start sites downstream to AV3 promoter were mapped to nucleotide positions 803 or 805 in E. coli, and 856 in Nicotiana benthamiana. The eukaryotic activity of AV3 promoter and the translatability of a short downstream open reading frame were further confirmed by using a green fluorescent protein reporter construct in yeast (Saccharomyces cerevisiae) cells. These results suggested that AV3 promoter might be a remnant of evolution that retained cryptic activity at present.

    The need for tools that can assist in evaluating visual function is an essential and a growing requirement as lasers on the modern battlefield mature and proliferate. The requirement for rapid and sensitive vision assessment under field conditions produced the USAMRD Aidman Vision Screener (AVS), designed to be used as a field diagnostic tool for assessing laser induced retinal damage. In this paper, we describe additions to the AVS designed to provide a more sensitive assessment of laser induced retinal dysfunction. The AVS incorporates spectral LogMar Acuity targets without and with neural opponent chromatic backgrounds. Thus, it provides the capability of detecting selective photoreceptor damage and its functional consequences at the level of both the outer and inner retina. Modifications to the original achromatic AVS have been implemented to detect selective cone system dysfunction by providing LogMar acuity Landolt rings associated with the peak spectral absorption regions of the S (short), M (middle), and L (long) wavelength cone photoreceptor systems. Evaluation of inner retinal dysfunction associated with selective outer cone damage employs LogMar spectral acuity charts with backgrounds that are neurally opponent. Thus, the AVS provides the capability to assess the effect of selective cone dysfunction on the normal neural balance at the level of the inner retinal interactions. Test and opponent background spectra have been optimized by using color space metrics. A minimal number of three AVS evaluations will be utilized to provide an estimate of false alarm level.

    Off-target binding in the basal ganglia is commonly observed in the 18 F-AV-1451 PET studies of the elderly. We sought to investigate the relationship between this phenomenon in the basal ganglia and iron accumulation using iron-sensitive R 2 * MRI. Methods: Fifty-nine healthy controls and 61 patients with Alzheimer disease and mild cognitive impairment underwent 18 F-AV-1451 PET and R 2 * MRI studies. A correlation analysis was performed for age, 18 F-AV-1451 binding, and R 2 * values. Results: There was an age-related increase in both 18 F-AV-1451 binding in the basal ganglia and R 2 * values in the putamen in both the controls and the Alzheimer disease/mild cognitive impairment patients. 18 F-AV-1451 binding in the basal ganglia increased with R 2 * values. Conclusion: Off-target 18 F-AV-1451 binding in the basal ganglia is associated with the age-related increases in iron accumulation. Postmortem studies are required to further investigate the nature of this association. © 2018 by the Society of Nuclear Medicine and Molecular Imaging.

    Twin AV nodal reentrant tachycardia most commonly occurs in patients with complex congenital heart disease who have two distinct AV nodes, His bundles, and non-preexcited QRS morphologies. Catheter ablation of the weaker AV node may be hindered by anatomical complexities. In such cases, remote magnetic guidance offers a potentially effective solution.

    The ability to intercalate between DNA strands determines the cytotoxic activity of numerous anticancer drugs. Strikingly, intercalating activity was also reported for some compounds considered to be antimutagenic. The aim of this study was to determine the mode of interaction of DNA with the antimutagenic and DNA repair-stimulating dihydropyridine (DHP) AV-153. DNA and AV-153 interactions were studied by means of UV/VIS spectroscopy, fluorimetry and infrared spectroscopy. Compound AV-153 is a 1,4 dihydropyridine with ethoxycarbonyl groups in positions 3 and 5. Computer modeling of AV-153 and DNA interactions suggested an ability of the compound to dock between DNA strands at a single strand break site in the vicinity of two pyrimidines, which was confirmed in the present study. AV-153 evidently interacted with DNA, as addition of DNA to AV-153 solutions resulted in pronounced hyperchromic and bathochromic effects on the spectra. Base modification in a plasmid by peroxynitrite only minimally changed binding affinity of the compound; however, induction of single-strand breaks using Fenton's reaction greatly increased binding affinity. The affinity did not change when the ionic strength of the solution was changed from 5 to 150 mM NaCl, although it increased somewhat at 300 mM. Neither was it influenced by temperature changes from 25 to 40°C, however, it decreased when the pH of the solution was changed from 7.4 to 4.7. AV-153 competed with EBr for intercalation sites in DNA: 116 mM of the compound caused a two-fold decrease in fluorescence intensity. FT-IR spectral data analyses indicated formation of complexes between DNA and AV-153. The second derivative spectra analyses indicated interaction of AV-153 with guanine, cytosine and thymine bases, but no interaction with adenine was detected. The antimutagenic substance AV-153 appears to intercalate between the DNA strands at the site of a DNA nick in the vicinity of two pyrimidines. Copyright © 2014 Elsevier

    Little is known about Alzheimer's disease molecular proteins, beta-amyloid and paired helical filament (PHF) tau, in progressive supranuclear palsy (PSP). Recent techniques have been developed to allow for investigations of these proteins in PSP. We determined the frequency of beta-amyloid deposition in PSP, and whether beta-amyloid deposition in PSP is associated with PHF-tau deposition pattern, or clinical features. Thirty probable PSP participants underwent MRI, [ 18 F]AV-1451 PET and Pittsburgh compound B (PiB) PET. Apolipoprotein (APOE) genotyping was also performed. A global PiB standard-uptake value ratio (SUVR) was calculated. AV-1451 SUVRs were calculated for a set of Alzheimer's disease (AD)-related regions and a set of PSP-related regions. Voxel-level analyses were conducted to assess for differences in AV-1451 uptake patterns and MRI atrophy between PiB(+) and PiB(-) cases compared to 60 normal PiB(-) controls. Statistical testing for correlations and associations between variables of interest were also performed. Twelve subjects (40%) showed beta-amyloid deposition. Higher PiB SUVR correlated with older age but not with AV-1451 SUVR in the AD- or PSP-related regions. Higher AV-1451 SUVR in AD-related regions was associated with higher AV-1451 SUVR in PSP-related regions. We found little evidence for beta-amyloid related differences in clinical metrics, proportion of APOE e4 carriers, pattern of AV-1451 uptake, or pattern of atrophy. Beta-amyloid deposition occurs in a relatively high proportion of PSP subjects. Unlike in Alzheimer's disease, however, there is little evidence that beta-amyloid, and PHF-tau, play a significant role in neurodegeneration in PSP. Copyright © 2017 Elsevier Ltd.

    Recent experiments on vanadium oxide bronzes AV 2 O 5 (A=Na, Mg, Li) are reviewed. Experiments are carried out combining two triple-axis spectrometers installed at a thermal beam port and a cold neutron guide at JRR-3M. Spin-wave excitations in single crystals NaV 2 O 5 in the spin-Peierls state shows a steep intra-chain dispersion, which is consistent with estimated exchange interaction from magnetization measurement, and a weak inter-chain dispersion. In the low energy excitation measurement on powder sample of MgV 2 O 5 , we have observed energy gap of 2 meV, which indicates that this material is a ladder system with strong 1D character. Preliminary result on LiV 2 O 5 , which is expected to be a simple 1D antiferromagnet or a zig-zag chain, is also mentioned

    Full Text Available Til tross for lærerutdanningers mangeårige arbeid med å finne innovative løsninger som skaper gode sammenhenger mellom campuskonteksten og skolekonteksten, etterlyser lærerstudentene fortsatt en bedre sammenheng i studiet. Det som kjennetegner metodene i mange lærerutdanninger er at de bygger på ideen om læring for praksis. Dette innebærer i stor grad forventninger om at studentene transformerer kunnskap fra campus til undervisning og refleksjon i skolen. Mye tyder på at lærerstudentene får lite hjelp i denne prosessen. Studier om koherens – eller sammenheng – i lærerutdanningen knyttes sjelden til at lærerutdanning kan innebære et læringsproblem. Hensikten med denne artikkelen er å undersøke de læringsutfordringer studenter har når kunnskap skal transformeres mellom de to kontekstene. Tanken er at en forståelse for lærerstudenters læring på denne måten kan bidra inn i arbeidet med å videreutvikle metoder i lærerutdanningen som kan lette transformeringsprosessene.

    HPCMP CREATE-AV Conservative Field Finite Element (COFFE) is a modular, extensible, robust numerical solver for the Navier-Stokes equations that invokes modularity and extensibility from its first principles. COFFE implores a flexible, class-based hierarchy that provides a modular approach consisting of discretization, physics, parallelization, and linear algebra components. These components are developed with modern software engineering principles to ensure ease of uptake from a user's or developer's perspective. The Streamwise Upwind/Petrov-Galerkin (SU/PG) method is utilized to discretize the compressible Reynolds-Averaged Navier-Stokes (RANS) equations tightly coupled with a variety of turbulence models. The mathematics and the philosophy of the methodology that makes up COFFE are presented.

    Full Text Available Vid Pedagogiska institutionen vid Umeå universitet har nätutbildningen expanderat kraftigt under de senaste två och ett halvt åren, då institutionen började ge fristående helfartskurser i pedagogik via Internet. Vårterminen 2008 läste cirka 60 studenter och inför varje termin har sedan studenttillströmningen ökat, för att under våren 2010 uppgå till 240 studenter. Hösten 2008 infördes, med stöd av interna utvecklingsmedel, examinerande portfoliouppgifter på samtliga nätbaserade kurser med målsättningen att möta de utmaningar som både formen (nätundervisning och den utökade och heterogena studentgruppen innebar. Syftet var att stärka studenternas förmåga att synliggöra sitt eget lärande, samt att minska anonymiteten mellan lärare och student. Uppgifterna var av självreflekterande karaktär där studenterna uppmanades att relatera det egna lärandet till kursinnehållet och att exempelvis identifiera framtida tillämpningsområden inom studier och arbetsliv. Studenterna fick under terminen individuell återkoppling av en och samma lärare. Intentionen med återkopplingen var bland annat att guida och uppmuntra studenterna till att inta ett personligt förhållningssätt till kursinnehållet. I artikeln argumenteras det för att portfoliometodik i flera avseenden kan sägas harmoniera väl med ett rådande synsätt på examination där ett sociokulturellt synsätt på lärande dominerar och livslångt lärande och självständighet framhålls som eftersträvansvärt. Detta medför att, det både utifrån ett student- och ett lärarperspektiv, kan kännas naturlig och relevant att använda portfolio som examinationsform inom nätutbildning. Samtidigt är det viktigt att problematisera och kritiskt reflektera över portfoliometodik som examinationsform och de förhållningssätt och ideal som skapas, vilket görs i artikeln med hjälp av en Foucaultinspirerad tolkningsram.

    Full Text Available Alexander V. Chayanov (1888-1937 is a famous Russian economist, theorist of the organization of economy, a brilliant representative of the generation of the “golden age” of the economic science in Russia. One of the key elements of his scientific legacy is the theory of non-capitalist forms of economy, and one of its aspects - international agrarian studies of the features of the organization of agriculture in different countries. The organizational-production school developed a theory of labor economy and came close to the general theory of non-capitalist forms of economy; however, its studies were inter-rupted by the repressions of the 1920s. The article considers the international studies of A.V. Chayanov to clarify and develop some findings of the today’s scholars (I.A. Kuznetsov, A.M. Nikulin, T.A. Savinova. The author proposes a new interpretation of the organizational-production school as having a dualistic character. The works of Alexander N. Chelintsev (1874-1962, Nicholay P. Makarov (1886-1980 and other colleagues of A.V. Chayanov from the organizational-production school focused on both theoretical issues such as the fundamental laws of functioning and development of agriculture, and practical issues of scientific management of an individual farm and agriculture in general. The author considers the orga-nizational-production school as dualistic: it studies both theory and management of peasant economy at micro- and macro-levels proceeding from the analysis of the individual farm structure to the issues of the optimal production location and optimal management of ‘a mass of peasant farms’. The system approach to the organization of economy, cooperation, zoning and economic policy developed by the organizational-production school is still relevant for the contemporary use.

    Abstract The ability to assess the distribution and extent of tau pathology in Alzheimer’s disease and progressive supranuclear palsy in vivo would help to develop biomarkers for these tauopathies and clinical trials of disease-modifying therapies. New radioligands for positron emission tomography have generated considerable interest, and controversy, in their potential as tau biomarkers. We assessed the radiotracer 18F-AV-1451 with positron emission tomography imaging to compare the distribution and intensity of tau pathology in 15 patients with Alzheimer’s pathology (including amyloid-positive mild cognitive impairment), 19 patients with progressive supranuclear palsy, and 13 age- and sex-matched controls. Regional analysis of variance and a support vector machine were used to compare and discriminate the clinical groups, respectively. We also examined the 18F-AV-1451 autoradiographic binding in post-mortem tissue from patients with Alzheimer’s disease, progressive supranuclear palsy, and a control case to assess the 18F-AV-1451 binding specificity to Alzheimer’s and non-Alzheimer’s tau pathology. There was increased 18F-AV-1451 binding in multiple regions in living patients with Alzheimer’s disease and progressive supranuclear palsy relative to controls [main effect of group, F(2,41) = 17.5, P AV-1451 binding was significantly increased in patients with Alzheimer’s disease, relative to patients with progressive supranuclear palsy and with control subjects, in the hippocampus and in occipital, parietal, temporal, and frontal cortices (t’s > 2.2, P’s AV-1451 binding was elevated in the midbrain (t = 2.1, P AV-1451 uptake in the putamen, pallidum, thalamus, midbrain, and in the dentate nucleus of the cerebellum (t’s > 2.7, P’s AV-1451 strongly bound to Alzheimer-related tau pathology, but less specifically in progressive supranuclear palsy. 18F-AV-1451 binding to the basal ganglia was strong in all groups in vivo.

    Background The mechanoenergetic effects of atrioventricular delay optimization during biventricular pacing (“cardiac resynchronization therapy”, CRT) are unknown. Methods Eleven patients with heart failure and left bundle branch block (LBBB) underwent invasive measurements of left ventricular (LV) developed pressure, aortic flow velocity-time-integral (VTI) and myocardial oxygen consumption (MVO2) at 4 pacing states: biventricular pacing (with VV 0 ms) at AVD 40 ms (AV-40), AVD 120 ms (AV-120, a common nominal AV delay), at their pre-identified individualised haemodynamic optimum (AV-Opt); and intrinsic conduction (LBBB). Results AV-120, relative to LBBB, increased LV developed pressure by a mean of 11(SEM 2)%, p = 0.001, and aortic VTI by 11(SEM 3)%, p = 0.002, but also increased MVO2 by 11(SEM 5)%, p = 0.04. AV-Opt further increased LV developed pressure by a mean of 2(SEM 1)%, p = 0.035 and aortic VTI by 4(SEM 1)%, p = 0.017. MVO2 trended further up by 7(SEM 5)%, p = 0.22. Mechanoenergetics at AV-40 were no different from LBBB. The 4 states lay on a straight line for Δexternal work (ΔLV developed pressure × Δaortic VTI) against ΔMVO2, with slope 1.80, significantly > 1 (p = 0.02). Conclusions Biventricular pacing and atrioventricular delay optimization increased external cardiac work done but also myocardial oxygen consumption. Nevertheless, the increase in cardiac work was ~ 80% greater than the increase in oxygen consumption, signifying an improvement in cardiac mechanoenergetics. Finally, the incremental effect of optimization on external work was approximately one-third beyond that of nominal AV pacing, along the same favourable efficiency trajectory, suggesting that AV delay dominates the biventricular pacing effect — which may therefore not be mainly “resynchronization”.

    To compare PET imaging of tau pathology with CSF measurements (total tau [t-tau] and phosphorylated tau [p-tau]) in terms of diagnostic performance for Alzheimer disease (AD). We compared t-tau and p-tau and 18 F-AV-1451 in 30 controls, 14 patients with prodromal AD, and 39 patients with Alzheimer dementia, recruited from the Swedish BioFINDER study. All patients with AD (prodromal and dementia) were screened for amyloid positivity using CSF β-amyloid 42. Retention of 18 F-AV-1451 was measured in a priori specified regions, selected for known associations with tau pathology in AD. Retention of 18 F-AV-1451 was markedly elevated in Alzheimer dementia and moderately elevated in prodromal AD. CSF t-tau and p-tau was increased to similar levels in both AD dementia and prodromal AD. 18 F-AV-1451 had very good diagnostic performance for Alzheimer dementia (area under the receiver operating characteristic curve [AUROC] ∼1.000), and was significantly better than t-tau (0.876), p-tau (0.890), hippocampal volume (0.824), and temporal cortical thickness (0.860). For prodromal AD, there were no significant AUROC differences between CSF tau and 18 F-AV-1451 measures (0.836-0.939), but MRI measures had lower AUROCs (0.652-0.769). CSF tau and 18 F-AV-1451 have equal performance in early clinical stages of AD, but 18 F-AV-1451 is superior in the dementia stage, and exhibits close to perfect diagnostic performance for mild to moderate AD. This study provides Class III evidence that CSF tau and 18 F-AV-1451 PET have similar performance in identifying early AD, and that 18 F-AV-1451 PET is superior to CSF tau in identifying mild to moderate AD. © 2018 The Author(s).

    Full Text Available Em virtude da grande demanda por proteína de origem animal, tem-se aumentado a produção de frangos de corte e consequentemente a geração de resíduos provenientes do abate de aves, sendo necessário o desenvolvimento de técnicas que permitam o aproveitamento e reciclagem desses materiais. Objetivou-se com a execução deste trabalho avaliar a eficiência da compostagem no tratamento e reciclagem do resíduo sólido de abatedouro avícola. Utilizou-se resíduo sólido de abatedouro avícola comercial composto por fragmentos de vísceras, tecido muscular, adiposo e ósseo, sangue coagulado e penas e, como fonte de carbono, a casca de arroz. Montou-se uma leira com 1,5m3 de volume inicial, na qual foram monitorados os parâmetros: temperatura, teores de sólidos totais (ST, voláteis (SV, N, P, K, carbono orgânico (C, matéria orgânica compostável (MOC, matéria orgânica resistente à compostagem (MORC, demanda química de oxigênio (DQO, massa e volume enleirados, número mais provável (NMP de coliformes totais e termotolerantes, bem como suas reduções durante o processo. A temperatura máxima atingida no centro da leira foi de 53,3ºC (média semanal, já as reduções de massa de ST e SV e volume durante o processo de pré-compostagem foram de 36,1; 44,3 e 23,3%, respectivamente, e, durante o processo de compostagem, foram de 21,8; 23,8 e 4,4%. A baixa redução do volume das leiras pode estar associada à alta concentração de MORC (40,1% que pode ser principalmente relacionada à qualidade da fonte de carbono. O processo promoveu satisfatórias reduções totais de ST, SV e volume, sendo, respectivamente, 50,1; 57,5 e 26,7%. No entanto, foram observadas reduções de 43% na quantidade de nitrogênio presente no composto final. Apesar das reduções de nitrogênio, a compostagem demonstrou ser um método eficiente no tratamento dos resíduos sólidos de abatedouro avícola.

    During the 2010 and 2011 Icelandic volcanic eruptions, the availability of integrated, validated data sets was identified as a major challenge in the effort to gain a rapid situation assessment. These environmental crisis situations may happen again, also from other types ofairborne hazards, like big fires. Currently, the issue is not so much that data and observations do not exist, it is rather the rapid accessibility, the cross-calibration of different sensors, the integration of new platforms and the harmonization of standards and protocols that needs further work and attention. A specific activity is planned within the H-2020 project EUNADICS -AV ("European Natural Disaster Coordination and Information System for Aviation") for addressing this critical issue. In order to achieve the rapid data accessibility, work will be carried out with full consideration of the main European Research Infrastructures, projects and national/international monitoring networks that are able to provide crucial information related to the dispersion of airborne hazards. The integrated data sets are based on satellite and ground-based remote sensing as well as in situ ground-based and aircraft observations. Networks of ground based remote sensing of atmospheric profiles are particularly important, since these will provide the needed height information that cannot be obtained unambiguously from the vast majority of space borne sensors. A new aspect not treated in any project and initiative so far is the integration of special crisis measurements, for example by aircraft or UAV systems. Particularly suited for the purposes of the project are satellite data from operational sensors aboard EUMETSAT and ESA satellites. Improved retrievals are investigated, and the new generation of Sentinel satellites currently being launched under the Copernicus umbrella and their added value are considered. Especially when the ground based and space borne observations are combined, the much needed

    Scientific audiovisual media such as videos of research, interactive displays or computer animations has become an important part of scientific communication and education. Dynamic phenomena can be described better by audiovisual media than by words and pictures. For this reason, scientific videos help us to understand and discuss environmental phenomena more efficiently. Moreover, the creation of scientific videos is easier than ever, thanks to mobile devices and open source editing software. Video-clips, webinars or even the interactive part of a PICO are formats of scientific audiovisual media used in the Geosciences. This type of media translates the location-referenced Science Communication such as environmental interpretation into computed-based Science Communication. A new way of Science Communication is video abstracting. A video abstract is a three- to five-minute video statement that provides background information about a research paper. It also gives authors the opportunity to present their research activities to a wider audience. Since this kind of media have become an important part of scientific communication there is a need for reliable infrastructures which are capable of managing the digital assets researchers generate. Using the reference of the usecase of video abstracts this paper gives an overview over the activities by the German National Library of Science and Technology (TIB) regarding publishing and linking audiovisual media in a scientifically sound way. The German National Library of Science and Technology (TIB) in cooperation with the Hasso Plattner Institute (HPI) developed a web-based portal (av.tib.eu) that optimises access to scientific videos in the fields of science and technology. Videos from the realms of science and technology can easily be uploaded onto the TIB|AV Portal. Within a short period of time the videos are assigned a digital object identifier (DOI). This enables them to be referenced, cited, and linked (e.g. to the

    Both the apolipoprotein A5 and C3 genes have repeatedly been shown to play an important role in determining plasma triglyceride concentrations in humans and mice. In mice, transgenic and knockout experiments indicate that plasma triglyceride levels are negatively and positively correlated with APOA5 and APOC3 expression, respectively. In humans, common polymorphisms in both genes have also been associated with plasma triglyceride concentrations. The evolutionary relationship among these two apolipoprotein genes and their close proximity on human chromosome 11q23 have largely precluded the determination of their relative contribution to altered Both the apolipoprotein A5 and C3 genes have repeatedly been shown to play an important role in determining plasma triglyceride concentrations in humans and mice. In mice, transgenic and knockout experiments indicate that plasma triglyceride levels are negatively and positively correlated with APOA5 and APOC3 expression, respectively. In humans, common polymorphisms in both genes have also been associated with plasma triglyceride concentrations. The evolutionary relationship among these two apolipoprotein genes and their close proximity on human chromosome 11q23 have largely precluded the determination of their relative contribution to altered triglycerides. To overcome these confounding factors and address their relationship, we generated independent lines of mice that either over-expressed (''double transgenic'') or completely lacked (''double knockout'') both apolipoprotein genes. We report that both ''double transgenic'' and ''double knockout'' mice display intermedia tetriglyceride concentrations compared to over-expression or deletion of either gene alone. Furthermore, we find that human ApoAV plasma protein levels in the ''double transgenic'' mice are approximately 500-fold lower than human ApoCIII levels, supporting ApoAV

  5. A Comparison of Interaction in AV-based and Internet-based Distance Courses

    Full Text Available At the center of the debate over the viability of distance education is whether the newer electronic technologies can offer enough interaction to maintain quality learner outcomes and critical mass. Two of the most commonly used forms of distance education are 1 two-way, fully interactive audio-video classrooms and 2 on-line instruction through the Internet or Worldwide Web. This study used qualitative methods to compare and contrast the interaction that occurred in distance learning courses offered via each medium. The research process confirmed findings that there were fundamental differences in the interaction that occurred in the two environments. On-line interaction is so profoundly different than interaction in the traditional and AV-based class room that it appears instructors and students will need a substantial period of adjustment to feel comfortable with it and to fully appreciate its value. It appears that, as distance teaching and learning moves to a “mixed media” approach to teaching and learning, how interaction is handled with each of the media may be important to the success of a distance program.

    Full Text Available Å forske med kunsten innebærer ikke bare valget av visse metoder for bruk i forskningsprosessen, men også om å ha til disposisjon spesifikke måter å tenke om metode. I denne artikkelen vil jeg synliggjøre en tenkemåte fundert i arbeidet med en skjønnlitterær lesesirkel for lærerstudenter, og min egen erfaring som improvisasjonsmusiker. Jazzens begrep om jam blir løftet frem som omdreiningspunkt for tenkemåten, som ellers har sitt teoretiske utspring i den franske filosofen Gilles Deleuze’s forestilling om bliven. Denne vitale forestillingen innebærer at verden produseres kontinuerlig, noe forskeren også bidrar til. Koblingen mellom jam, litteratur og Deleuze synliggjør dessuten en måte å tenke om metode på som understreker at det å forske med kunsten ikke bare betyr å forske på kunsten, men at kunsten på ulike måter kan virke inn på selve forskningen og slik også bidra til å affirmere verden i sin bliven. I tillegg til å tilby en måte å tenke om metode for den som skal forske med kunsten, er hensikten med artikkelen å gjøre forskeren bevisst sin egen tenkning om metode, noe som er viktig siden denne skaper mulighetsbetingelser for metodevalg og -bruk.

    Dias, Tiago; Roma, Nuno; Sousa, Leonel

    2014-12-01

    A unified architecture for fast and efficient computation of the set of two-dimensional (2-D) transforms adopted by the most recent state-of-the-art digital video standards is presented in this paper. Contrasting to other designs with similar functionality, the presented architecture is supported on a scalable, modular and completely configurable processing structure. This flexible structure not only allows to easily reconfigure the architecture to support different transform kernels, but it also permits its resizing to efficiently support transforms of different orders (e.g. order-4, order-8, order-16 and order-32). Consequently, not only is it highly suitable to realize high-performance multi-standard transform cores, but it also offers highly efficient implementations of specialized processing structures addressing only a reduced subset of transforms that are used by a specific video standard. The experimental results that were obtained by prototyping several configurations of this processing structure in a Xilinx Virtex-7 FPGA show the superior performance and hardware efficiency levels provided by the proposed unified architecture for the implementation of transform cores for the Advanced Video Coding (AVC), Audio Video coding Standard (AVS), VC-1 and High Efficiency Video Coding (HEVC) standards. In addition, such results also demonstrate the ability of this processing structure to realize multi-standard transform cores supporting all the standards mentioned above and that are capable of processing the 8k Ultra High Definition Television (UHDTV) video format (7,680 × 4,320 at 30 fps) in real time.

    Aeromonas molluscorum Av27 is an estuarine bacterium highly resistant to tributyltin (TBT). Also, the strain is able to degrade TBT into the less toxic compounds dibutyltin and monobutyltin. Therefore, this bacterium has potential to be employed in bioremediation processes. In this context, defining its biological safety is crucial. With that purpose a number of intrinsic characteristics, usually present/associated with virulent strains, were investigated. Few virulence factors were detected in strain Av27. For instance, a DNase gene is present, but it is not apparently expressed in vitro. Motility, adherence factor and phospholipase activity were also detected. Additionally, cytotoxicity to Vero cells was negative. Resistance to penicillin (10 μg ml(-1)), amoxicillin/clavulanic acid (30 μg ml(-1)) and cephalothin (30 μg ml(-1)) and also to the vibriostatic agent O/129 was observed. Five plasmids (4, 7, 10, 100 kb and one greater than 100 kb) were identified. No Class I and II integrons were detected. Study of the optimal growth conditions showed that Av27 easily adapts to different environmental conditions. Overall, the results suggest that A. molluscorum Av27 can be considered safe to use to bioremediate TBT in contaminated environments.

    Abstract Tau positron emission tomography ligands provide the novel possibility to image tau pathology in vivo. However, little is known about how in vivo brain uptake of tau positron emission tomography ligands relates to tau aggregates observed post-mortem. We performed tau positron emission tomography imaging with 18F-AV-1451 in three patients harbouring a p.R406W mutation in the MAPT gene, encoding tau. This mutation results in 3- and 4-repeat tau aggregates similar to those in Alzheimer’s disease, and many of the mutation carriers initially suffer from memory impairment and temporal lobe atrophy. Two patients with short disease duration and isolated memory impairment exhibited 18F-AV-1451 uptake mainly in the hippocampus and adjacent temporal lobe regions, correlating with glucose hypometabolism in corresponding regions. One patient died after 26 years of disease duration with dementia and behavioural deficits. Pre-mortem, there was 18F-AV-1451 uptake in the temporal and frontal lobes, as well as in the basal ganglia, which strongly correlated with the regional extent and amount of tau pathology in post-mortem brain sections. Amyloid-β (18F-flutemetamol) positron emission tomography scans were negative in all cases, as were stainings of brain sections for amyloid. This provides strong evidence that 18F-AV-1451 positron emission tomography can be used to accurately quantify in vivo the regional distribution of hyperphosphorylated tau protein. PMID:27357347

    Patients with Alzheimer's disease can present with different clinical phenotypes. Individuals with late-onset Alzheimer's disease (>65 years) typically present with medial temporal lobe neurodegeneration and predominantly amnestic symptomatology, while patients with early-onset Alzheimer's disease (AV-1451 tau positron emission tomography and structural magnetic resonance imaging to explore whether early- and late-onset Alzheimer's disease exhibit differential regional tau pathology and atrophy patterns. Strong associations of lower age at symptom onset with higher 18F-AV-1451 uptake were observed in several neocortical regions, while higher age did not yield positive associations in neither patient group. Comparing patients with early-onset Alzheimer's disease with controls resulted in significantly higher 18F-AV-1451 retention throughout the neocortex, while comparing healthy controls with late-onset Alzheimer's disease patients yielded a distinct pattern of higher 18F-AV-1451 retention, predominantly confined to temporal lobe regions. When compared against each other, the early-onset Alzheimer's disease group exhibited greater uptake than the late-onset group in prefrontal and premotor, as well as in inferior parietal cortex. These preliminary findings indicate that age may constitute an important contributor to Alzheimer's disease heterogeneity highlighting the potential of tau positron emission tomography to capture phenotypic variation across patients with Alzheimer's disease. © The Author (2017).

    To determine whether specific patterns of [ 18 F]-AV-1451 tau-PET retention are observed in patients with autopsy-proven sporadic Creutzfeldt-Jakob disease (CJD). In vivo [ 18 F]-AV-1451 PET neuroimaging was performed in 5 patients with sporadic CJD (median age, 66 years [63-74]), and results were compared to cognitively normal (CN) persons (n = 44; median age, 68 years [63-74]) and to participants with very mild Alzheimer disease (AD) dementia (n = 8; median age, 77 years [63-90]). Autopsy was completed in all patients with CJD, confirming the clinical diagnosis and permitting characterization of AD neuropathologic change (ADNC). All patients with CJD presented with rapidly progressive dementia, typical magnetic resonance brain imaging changes, and elevated CSF total tau (median = 6,519; range = 1,528-13,240 pg/mL). Death occurred within 9 months of symptom onset, with a median 1 month (0.2-3.3) interval from [ 18 F]-AV-1451 PET to autopsy. No unique pattern of [ 18 F]-AV-1451 retention was observed on visual inspection. Summary standardized uptake value ratios in patients with CJD (1.17, 1.08-1.36) were indistinguishable from CN persons (1.14, 0.84-1.54; p = 0.6), and well below those of participants with AD (2.23, 1.60-3.04; p ≤ 0.01). [ 18 F]-AV-1451 retention in patients with CJD and CN persons was similar in brain areas frequently affected in AD and CJD. Neuropathologic analysis confirmed the clinical diagnosis in all patients with CJD. Four patients with CJD also had low-level ADNC (A1B1C0); one patient had intermediate-level ADNC (A2B2C1/2). Increased [ 18 F]-AV-1451 retention was not observed in patients with rapidly progressive dementia due to sporadic CJD. The [ 18 F]-AV-1451 PET tracer maintains good specificity for paired helical tau filaments associated with AD dementia. © 2018 American Academy of Neurology.

    Full Text Available Artikkelen ønsker å gi et konstruktivt bidrag til forståelsen og anvendelsen av fair play i en kroppsøvingsfaglig kontekst. Dette er et tema som er blitt aktualisert i og med at fair play er kommet inn som et sentralt element i kroppsøvingsfagets nye reviderte læreplan. Fair play omhandler regler, normer og verdier som skal gjelde ved idrettsutøvelse, og det er et etablert verdikonsept innenfor organisert idrettsliv og idrettsetisk forskning. I skolen, derimot, er fair play mindre kjent. Kroppsøvingsplanen hevder fair play omfatter aspekter ved idrettsspillet som å overholde regler, vise hverandre respekt og gjøre hverandre gode. Hva betyr så dette? Hva vil det si å gjøre hverandre gode? Rommer det bare en teknisk eller også en sosialetisk kvalitet? Dersom det siste er tilfelle, bør det diskuteres hvilke danningskvaliteter det så ligger i det å gjøre hverandre gode i faget, og om disse har noen tilknytningspunkt til Aristoteles' klassiske dyder om rettferdighet, måtehold, mot og klokskap. Dette er de sentrale spørsmålene artikkelen reiser og prøver å gi noen svar på. Artikkelen ser først på fair play i kroppsøvingsfagets planer, for deretter å gi begrepet en nærmere etymologisk og ideologisk-historisk avklaring, med utgangspunkt i begrepene «fair» og «play».

    Commercial aviation is one of the key infrastructures of our modern world. Even short interruptions can cause economic damages summing up to the Billion-Euro range. As evident from the past, aviation shows vulnerability with regard to natural hazards. Safe flight operations, air traffic management and air traffic control is a shared responsibility of EUROCONTROL, national authorities, airlines and pilots. All stakeholders have one common goal, namely to warrant and maintain the safety of flight crews and passengers. Currently, however, there is a significant gap in the Europe-wide availability of real time hazard measurement and monitoring information for airborne hazards describing "what, where, how much" in 3 dimensions, combined with a near-real-time European data analysis and assimilation system. This gap creates circumstances where various stakeholders in the system may base their decisions on different data and information. The H-2020 project EUNADICS-AV ("European Natural Disaster Coordination and Information System for Aviation"), started in October 2016, intends to close this gap in data and information availability, enabling all stakeholders in the aviation system to obtain fast, coherent and consistent information. The project intends to combine and harmonize data from satellite earth observation, ground based and airborne platforms, and to integrate them into state-of-the art data assimilation and analysis systems. Besides operational data sources, data from the research community are integrated as well. Hazards considered in the project include volcano eruptions, nuclear accidents and events, and forest fires. The availability of consistent and coherent data analysis fields based on all available measurements will greatly enhances our capability to respond to disasters effectively and efficiently, minimizing system downtimes and thus economic damage while maintaining the safety of millions of passengers.

    Full Text Available Il contributo propone una lettura delle possibili influenze della realizzazione delle reti AV sulla localizzazione/distribuzione di attività di eccellenza, quali attività direzionali, di management, di servizio alle imprese e alla pubblica amministrazione, con specifico riferimento alla tratta AV Roma-Napoli. A partire da una caratterizzazione delle attività di eccellenza, se ne evidenzia anzitutto la spiccata tendenza alla concentrazione urbana, la dipendenza da efficaci connessioni sia immateriali che materiali e la rilevanza assunta dalla variabile temporale nelle scelte localizzative (Sassen, 2001. Quindi, in riferimento ad alcune esperienze europee, si esaminano i principali effetti, in termini di attrazione/concentrazione di tali attività, connessi alla realizzazione delle reti AV (Sands 1993; Vickerman e Ulied, 2006; Gemeente Amsterdam, 2007. Sulla base di tali considerazioni e tenendo conto delle più recenti definizioni e metodi di misura dell’accessibilità (Axhausen et al. 2006; Spiekermann, Wegener, 2005, lo studio propone un indicatore di “accessibilità” finalizzato ad individuare e graduare, in ragione dei livelli di accessibilità, un sistema di luoghi urbani interconnessi mediante reti su ferro (AV e reti metropolitane e regionali dai quali le attività di eccellenza potranno massimizzare il proprio bacino di utenza. L’individuazione di un sistema di luoghi urbani a diverso grado di accessibilità consente di evidenziare le numerose opportunità per la localizzazione di attività di eccellenza che si dischiudono a seguito della riduzione dei tempi di spostamento consentita dalle reti AV. In tal senso, l’indicatore proposto può costituire un utile supporto alle decisioni sia per l’attore pubblico consentendo di governare e orientare i processi di trasformazione conseguenti alla realizzazione della rete AV, estendendone i benefici dalle aree di stazione a più ampie porzioni urbane sia per l’investitore privato

    The demand for streaming video content is on the rise and growing exponentially. Networks bandwidth is very costly and therefore there is a constant effort to improve video compression rates and enable the sending of reduced data volumes while retaining quality of experience (QoE). One basic feature that utilizes the spatial correlation of pixels for video compression is Intra-Prediction, which determines the codec's compression efficiency. Intra prediction enables significant reduction of the Intra-Frame (I frame) size and, therefore, contributes to efficient exploitation of bandwidth. In this presentation, we propose new Intra-Prediction algorithms that improve the AV1 prediction model and provide better compression ratios. Two (2) types of methods are considered: )1( New scanning order method that maximizes spatial correlation in order to reduce prediction error; and )2( New Intra-Prediction modes implementation in AVI. Modern video coding standards, including AVI codec, utilize fixed scan orders in processing blocks during intra coding. The fixed scan orders typically result in residual blocks with high prediction error mainly in blocks with edges. This means that the fixed scan orders cannot fully exploit the content-adaptive spatial correlations between adjacent blocks, thus the bitrate after compression tends to be large. To reduce the bitrate induced by inaccurate intra prediction, the proposed approach adaptively chooses the scanning order of blocks according to criteria of firstly predicting blocks with maximum number of surrounding, already Inter-Predicted blocks. Using the modified scanning order method and the new modes has reduced the MSE by up to five (5) times when compared to conventional TM mode / Raster scan and up to two (2) times when compared to conventional CALIC mode / Raster scan, depending on the image characteristics (which determines the percentage of blocks predicted with Inter-Prediction, which in turn impacts the efficiency of the new

    [F-18]-AV-1451 is a novel positron emission tomography (PET) tracer with high affinity to neurofibrillary tau pathology in Alzheimer's disease (AD). PET studies have shown increased tracer retention in patients clinically diagnosed with dementia of AD type and mild cognitive impairment in regions that are known to contain tau lesions. In vivo uptake has also consistently been observed in midbrain, basal ganglia and choroid plexus in elderly individuals regardless of their clinical diagnosis, including clinically normal whose brains are not expected to harbor tau pathology in those areas. We and others have shown that [F-18]-AV-1451 exhibits off-target binding to neuromelanin, melanin and blood products on postmortem material; and this is important for the correct interpretation of PET images. In the present study, we further investigated [F-18]-AV-1451 off-target binding in the first autopsy-confirmed Parkinson's disease (PD) subject who underwent antemortem PET imaging. The PET scan showed elevated [F-18]-AV-1451 retention predominantly in inferior temporal cortex, basal ganglia, midbrain and choroid plexus. Neuropathologic examination confirmed the PD diagnosis. Phosphor screen and high resolution autoradiography failed to show detectable [F-18]-AV-1451 binding in multiple brain regions examined with the exception of neuromelanin-containing neurons in the substantia nigra, leptomeningeal melanocytes adjacent to ventricles and midbrain, and microhemorrhages in the occipital cortex (all reflecting off-target binding), in addition to incidental age-related neurofibrillary tangles in the entorhinal cortex. Additional legacy postmortem brain samples containing basal ganglia, choroid plexus, and parenchymal hemorrhages from 20 subjects with various neuropathologic diagnoses were also included in the autoradiography experiments to better understand what [F-18]-AV-1451 in vivo positivity in those regions means. No detectable [F-18]-AV-1451 autoradiographic binding was

    Full Text Available Lärande om molekylära processer kan innebära vissa svårigheter dels för att dessa processer inte går att direkt erfara och dels för att de är dynamiska i sin natur. Ett sätt att överbrygga problematiken är att använda sig av olika representationer, vilket i sig medför ytterligare utmaningar. Studenters förkunskaper och intuitiva idéer som härstammar från vardagserfarenheter kan också ge upphov till svårigheter i meningsskapandet. Syftet med denna artikel är att diskutera erfarenhetens och reflektionens betydelse för undervisning och lärande med representationer av molekylära fenomen i högre utbildning. I artikeln presenteras empiriska resultat från forskningsstudier som ligger till grund för de idéer och resonemang som förs fram. Vi presenterar två exempel där studenter arbetar i grupp med representationer av de molekylära processerna ATP-syntes och självassociation. Grunden för grupparbetet och meningsskapandet är fokuserade frågor där egna tankar och idéer får ta plats. Reflektionen i grupparbetet ger också studenterna möjligheter att generalisera sina erfarenheter (abstrakt tänkande och underlättar förståelsen av tröskelbegrepp.

Given the increasing success of the GIFT workshops held in conjunction with the General Assemblies, since 2010 EGU has also developed a series of GIFT workshops held in conjunction with AvH conferences. Associated GIFT workshops were held in Merida, Yucatan, on the theme of Climate Change, Natural Hazards and Societies (March 2010), then in Penang, Malaysia (June 2011) on the theme of Ocean Acidification, in November 2012 in Cusco (Peru) on the theme of Natural Disasters, Global Change and the Preservation of World Heritage Sites, finally in Istanbul (March 2014) on "High Impact Natural Hazards Related to the Euro-Mediterranean Region. The next GIFT workshop is already planned for October 2015 in Adis Ababa (Ethiopia) on the theme "Water". In each case, the GIFT workshop was held on the last two days of the AvH conference and reunited 40-45 teachers from the nation where the AvH was held. Keynote speakers from AvH were speakers to the GIFT workshops which also included hands-on activities animated by sciences educators. These GIFT workshops represented the first workshops specifically aimed at teachers held in the country, and therefore represents a significant Earth Sciences contribution to secondary education in non European countries.

    Adaptive cardiac resynchronization therapy (aCRT) is a dynamic optimization algorithm which paces only the left ventricle (LV) when atrio-ventricular (AV) conduction is normal, thus reducing right ventricular (RV) pacing. However, the impact of QRS duration on aCRT efficacy remains uncertain. We examined whether QRS duration impacts aCRT effectiveness in patients with left bundle branch block (LBBB) and preserved AV conduction. Randomized patients in the Adaptive CRT trial, which enrolled NYHA III/IV patients, were used in this analysis. Patients were randomized to receive aCRT or echo-optimized bi-ventricular CRT (control arm). Endpoints for this analysis were clinical composite score (CCS) at 6months post-implant and time to first heart failure (HF) hospitalization or death. Among the 199 patients with LBBB and normal AV intervals at baseline, 80 patients (40%) had a baseline moderately wide QRS of 120-150ms. In this subgroup, a greater proportion of aCRT patients had an improved CCS (79% vs. 50%) at 6months compared to the control group (p=0.03). There was also a trend toward a lower risk of death or HF hospitalization (hazard ratio: 0.53; 95% CI: 0.24-1.15; p=0.10) in the moderately wide QRS subgroup with aCRT compared to the control arm. In the wide QRS subgroup, the efficacy was comparable in both treatment arms. Adaptive CRT was associated with improved patient outcomes over echo-optimized bi-ventricular CRT in patients with preserved AV conduction, LBBB, and moderately wide QRS. The adaptive cardiac resynchronization therapy trial (ClinicalTrials.gov Identifier: NCT00980057) was sponsored by Medtronic plc, Mounds View, MN. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Los cambios sustantivos en el sistema agroalimentario mexicano han impulsado a las empresas a aplicar estrategias que les permitan funcionar en un contexto cada vez más competitivo, complejo e incierto. En el ramo avícola, Industrias Bachoco ha logrado posicionarse como líder nacional, a pesar de las presiones de la apertura comercial y de la competencia interna de dos de los mayores consorcios avícolas transnacionales. El presente artículo destaca los resultados obtenidos por esta empresa a partir de su estrategia de desplazamiento por la república mexicana. Desde la perspectiva de la teoría de la localización y de la nueva geografía económica, se plantea la hipótesis de que tal estrategia le ha permitido a Bachoco sumar ventajas comparativas regionales y le ha conferido la capacidad de suministrar una oferta adaptada a las costumbres y tradiciones de cada mercado regional, que no ha sido igualada por ninguna de sus competidoras. Se concluye que la apertura total inminente del mercado avícola mexicano inducirá al consorcio a acelerar su actualización, para estar a tono y competir con las empresas internacionales.

    The vesicular monoamine transporter type 2 (VMAT2) is highly expressed in pancreatic {beta}-cells and thus has been proposed to be a potential target for measuring {beta}-cell mass (BCM) by molecular imaging. C-11- and F-18-labeled tetrabenazine derivatives targeting VMAT2 have shown some promising results as potential biomarkers for BCM. In the present study, we examined the binding characteristics of 9-fluoropropyl-(+)-dihydrotetrabenzazine ([{sup 18}F]AV-133), a potential PET tracer for BCM imaging, in rat pancreas and rat brain. Methods: Pancreatic exocrine cells and pancreatic islet cells were isolated and purified from Sprague-Dawley rats. Membrane homogenates, prepared from both pancreatic exocrine and islet cells as well as from brain striatum and hypothalamus regions, were used for in vitro binding studies. In vitro and ex vivo autoradiography studies with [{sup 18}F]AV-133 were performed on rat brain and rat pancreas sections. Immunohistochemistry studies were performed to confirm the distribution of VMAT2 on islet {beta}-cells. Results: Excellent binding affinities of [{sup 18}F]AV-133 were observed in rat striatum and hypothalamus homogenates with K{sub d} values of 0.19 and 0.25 nM, respectively. In contrast to single-site binding observed in rat striatum homogenates, rat islet cell homogenates showed two saturable binding sites (site A: K{sub d}=6.76 nM, B{sub max}=60 fmol/mg protein; site B: K{sub d}=241 nM, B{sub max}=1500 fmol/mg protein). Rat exocrine pancreas homogenates showed only a single low-affinity binding site (K{sub d}=209 nM), which was similar to site B in islet cells. In vitro autoradiography of [{sup 18}F]AV-133 using frozen sections of rat pancreas showed specific labeling of islets, as evidenced by co-localization with anti-insulin antibody. Ex vivo VMAT2 pancreatic autoradiography in the rat, however, was not successful, in contrast to the excellent ex vivo autoradiography of VMAT2 binding sites in the brain. In vivo/ex vivo islet

    18 F-AV-1451 is currently the most widely used of several experimental tau PET tracers. The objective of this study was to evaluate 18 F-AV-1451 binding with full kinetic analysis using a metabolite-corrected arterial input function and to compare parameters derived from kinetic analysis with SUV ratio (SUVR) calculated over different imaging time intervals. Methods: 18 F-AV-1451 PET brain imaging was completed in 16 subjects: 4 young healthy volunteers (YHV), 4 aged healthy volunteers (AHV), and 8 Alzheimer disease (AD) subjects. Subjects were imaged for 3.5 h, with arterial blood samples obtained throughout. PET data were analyzed using plasma and reference tissue-based methods to estimate the distribution volume, binding potential (BP ND ), and SUVR. BP ND and SUVR were calculated using the cerebellar cortex as a reference region and were compared across the different methods and across the 3 groups (YHV, AHV, and AD). Results: AD demonstrated increased 18 F-AV-1451 retention compared with YHV and AHV based on both invasive and noninvasive analyses in cortical regions in which paired helical filament tau accumulation is expected in AD. A correlation of R 2 > 0.93 was found between BP ND (130 min) and SUVR-1 at all time intervals. Cortical SUVR curves reached a relative plateau around 1.0-1.2 for YHV and AHV by approximately 50 min, but increased in AD by up to approximately 20% at 110-130 min and approximately 30% at 160-180 min relative to 80-100 min. Distribution volume (130 min) was lower by 30%-35% in the YHV than AHV. Conclusion: Our data suggest that although 18 F-AV-1451 SUVR curves do not reach a plateau and are still increasing in AD, an SUVR calculated over an imaging window of 80-100 min (as currently used in clinical studies) provides estimates of paired helical filament tau burden in good correlation with BP ND , whereas SUVR sensitivity to regional cerebral blood changes needs further investigation. © 2017 by the Society of Nuclear Medicine and

    We have developed an ethanol-free formulation method of [(18) F]florbetapir ([(1) (8) F]AV-45) using a commercially available automated JFE multi-purpose synthesizer. We have also evaluated the radiochemical stability in an ethanol-free solution of [(18) F]AV-45 under visible light irradiation and dark conditions by comparison with a conventional 10% ethanol solution of [(18) F]AV-45. [(18) F]AV-45 was obtained with a radiochemical yield of 55.1 ± 2.2% (decay-corrected to end of bombardment), specific activity of 591.6 ± 90.3 GBq/µmol and radiochemical purity of >99% within a total synthesis time of about 73 min. The radiochemical purity of [(18) F]AV-45 formulated by dissolving the ethanol-free solution was found to decrease as a function of the period of exposure to visible light. In contrast, the visible light photolysis could be suppressed by adding 10% ethanol to the formulation or by avoiding exposure to visible light. In the radiosynthesis of [(18) F]AV-45 formulated by dissolving the ethanol-free solution, [(18) F]AV-45 could be obtained with high radiochemical purity and high stability by avoiding exposure to visible light.

    Thrombosis of native arteriovenous (AV) fistula is an important cause of complications in hemodialysis (HD) patients. The purpose of this study was to investigate the usefulness of measuring circulating fibroblast growth factor-23 (FGF-23) level and paraoxonase-1 (PON1) lactonase activity as potential predictors of native AV fistula thrombosis in chronic HD patients. This study included 83 HD patients (48 with thrombosed and 35 with non-thrombosed native AV fistulas) and 38 healthy volunteers. Serum FGF-23 level was measured using the ELISA technique, while serum PON1 lactonase activity was measured spectrophotometrically using gamma-thiobutyrolactone as a substrate. FGF-23 was significantly increased while PON1 lactonase was markedly decreased in both thrombosed and non-thrombosed HD patients compared with controls (P AV fistulas compared with HD patients with non-thrombosed native AV fistulas (P = 0.001 and 0.002, respectively). A significant negative correlation was found between FGF-23 and PON1 lactonase in HD patients with thrombosed native AV fistulas (r = -0.342, P = 0.017). This study shows a potential value of FGF-23 and PON1 lactonase as predictors of native AV fistula thrombosis in HD patients.

    Tau accumulation is a core pathologic change in various neurodegenerative diseases including Alzheimer's disease and frontotemporal lobar degeneration-tau. Recently, tau positron emission tomography tracers such as [ 18 F] AV-1451 and [ 18 F] THK5351 have been developed to detect tau deposition in vivo. In the present study, we performed a head to head comparison of these two tracers in Alzheimer's disease and frontotemporal dementia cases and aimed to investigate which tracers are better suited to image tau in these disorders. A cross-sectional study was conducted using a hospital-based sample at a tertiary referral center. We recruited eight participants (two Alzheimer's disease, four frontotemporal dementia and two normal controls) who underwent magnetic resonance image, amyloid positron emission tomography with [ 18 F]-Florbetaben and tau positron emission tomography with both THK5351 and AV-1451. To measure regional AV1451 and THK5351 uptakes, we used the standardized uptake value ratios by dividing mean activity in target volume of interest by mean activity in the cerebellar hemispheric gray matter. Although THK5351 and AV-1451 uptakes were highly correlated, cortical uptake of AV-1451 was more striking in Alzheimer's disease, while cortical uptake of THK5351 was more prominent in frontotemporal dementia. THK5351 showed higher off-target binding than AV-1451 in the white matter, midbrain, thalamus, and basal ganglia. AV-1451 is more sensitive and specific to Alzheimer's disease type tau and shows lower off-target binding, while THK5351 may mirror non-specific neurodegeneration.

    Full Text Available Background: Posterior cortical atrophy (PCA is characterized by progressive higher-order visuoperceptual dysfunction and praxis declines. This syndrome is related to a number of underlying diseases, including, in most cases, Alzheimer's disease (AD. The aim of this study was to compare the amyloid load with 18F-AV45 positron emission tomography (PET between PCA and AD subjects. Methods: We performed 18F-AV45 PET, cerebrospinal fluid (CSF biomarker analysis and a neuropsychological assessment in 11 PCA patients and 12 AD patients. Results: The global and regional 18F-AV45 uptake was similar in the PCA and AD groups. No significant correlation was observed between global 18F-AV45 uptake and CSF biomarkers or between regional 18F-AV45 uptake and cognitive and affective symptoms. Conclusion: This 18F-AV45 PET amyloid imaging study showed no specific regional pattern of cortical 18F-AV45 binding in PCA patients. These results confirm that a distinct clinical phenotype in amnestic AD and PCA is not related to amyloid distribution.

    Cerebral glucose metabolism measured with [18F]-FDG PET is a well established marker of neuronal dysfunction in neurodegeneration. The tau-protein tracer [18F]-AV-1451 PET is currently under evaluation and shows promising results. Here, we assess the feasibility of early perfusion imaging with AV-1451 as a substite for FDG PET in assessing neuronal injury. Twenty patients with suspected neurodegeneration underwent FDG and early phase AV-1451 PET imaging. Ten one-minute timeframes were acquired after application of 200 MBq AV-1451. FDG images were acquired on a different date according to clinical protocol. Early AV-1451 timeframes were coregistered to individual FDG-scans and spatially normalized. Voxel-wise intermodal correlations were calculated on within-subject level for every possible time window. The window with highest pooled correlation was considered optimal. Z-transformed deviation maps (ZMs) were created from both FDG and early AV-1451 images, comparing against FDG images of healthy controls. Regional patterns and extent of perfusion deficits were highly comparable to metabolic deficits. Best results were observed in a time window from 60 to 360 s (r = 0.86). Correlation strength ranged from r = 0.96 (subcortical gray matter) to 0.83 (frontal lobe) in regional analysis. ZMs of early AV-1451 and FDG images were highly similar. Perfusion imaging with AV-1451 is a valid biomarker for assessment of neuronal dysfunction in neurodegenerative diseases. Radiation exposure and complexity of the diagnostic workup could be reduced significantly by routine acquisition of early AV-1451 images, sparing additional FDG PET. (orig.)

    Recently, 9-[(18)F]fluoropropyl-(+)-dihydrotetrabenazine ((18)F-AV-133) was reported as a new vesicular monoamine transporter (VMAT2) imaging agent for diagnosis of Parkinson's disease (PD). To shorten the preparation of (18)F-AV-133 and to make it more widely available, we evaluated a simple, rapid purification with a solid-phase extraction method (SPE) using an Oasis HLB cartridge instead of high pressure liquid chromatography (HPLC). The SPE method produced doses containing a pseudo-carrier, 9-hydroxypropyl-(+)-dihydrotetrabenazine (AV-149). To test the possible side effects of this pseudo-carrier, comparative dynamic PET scans of the brains of normal monkeys (2 each) and uni-laterally 6-OH-dopamine-lesioned PD monkeys (2 each) were performed using (18)F-AV-133 doses prepared by either SPE (containing pseudo-carrier) or HPLC (containing no pseudo-carrier). Autoradiographs of post mortem monkey brain sections were evaluated to confirm the relative (18)F-AV-133 uptake in the PD monkey brains and the effects of the pseudo-carrier on VMAT2 binding. The radiochemical purity of the (18)F-AV-133, whether prepared by SPE or by HPLC, was excellent (>99%). PET scans of normal and PD monkey brains showed an expected reduction of VMAT2 in the lesioned areas of the striatum. It was not affected by the presence of the pseudo-carrier, AV-149 (maximally 250 μg/dose). The reduced uptake in the striatum of the lesioned monkey brains was confirmed by autoradiography. Ex vivo inhibition studies of (18)F-AV-133 binding in rat brains, conducted with increasing amounts of AV-149, suggested that at the highest concentration (3.5mg/kg) the VMAT2 binding in the striatum was only moderately blocked (20% reduction). The pseudo-carrier, AV-149, did not affect the (18)F-AV-133/PET imaging of VMAT2 binding sites in normal or uni-laterally lesioned monkey brains. The new streamlined SPE purification method will enable (18)F-AV-133 to be widely available for routine clinical application in

    A number of studies argue in favour of an important role of microbial colonization, in particular of Staphylococcus aureus, in triggering atopic dermatitis (AD) flare-up and psoriasis, in particular through the superantigenic properties of toxins generated by S. aureus. The aim of this study was to assess the efficacy of a 3-week Avène hydrotherapy on the skin surface of patients suffering from psoriasis or atopic dermatitis. Skin samples were taken from healthy subjects or atopic (n = 18) or psoriatic patients (n = 39) undergoing hydrotherapy at Avène at the beginning (D0) and the end of treatment (D18). The severity of the dermatosis was evaluated according to SCORing Atopic Dermatitis (SCORAD) or Psoriasis Area Severity Index (PASI) scores at D0 and D18. Marker of inflammation interleukin 8 (IL-8), S. aureus colonization (protein A) and enterotoxins were assessed in skin samples using RT-PCR. At D0, significant differences were observed between healthy subjects and atopic or psoriatic patients in all the parameters evaluated (IL-8, protein A). At the end of the hydrotherapy, a significant decrease in SCORAD was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin D in patients with atopic dermatitis. Similarly, a significant decrease in PASI was associated with a significant reduction of IL-8, S. aureus colonization and enterotoxin N in patients with psoriasis. This study demonstrates the positive effects of Avène hydrotherapy on the skin of patients suffering from chronic dermatosis, with decreased inflammation and reduced colonization by S. aureus. © 2010 The Authors.

    Utgangspunktet for denne oppgaven er den amerikanske sosiologen Peter L. Bergers bok The Sacred Canopy fra 1967 og hans artikkel The Desecularization of the World fra 1999. I Del 2 av The Sacred Canopy fremmet Berger sin opprinnelige sekulariseringsteori. Dette er en forholdsvis konvensjonell teori i den forstand at den ikke ligger langt unna datidens etablerte sosiologiske kunnskap. Følgelig tilsier den at religionen svekkes kraftig i møtet med moderniteten. Ikke nødvendigvis så kraftig at...

    18 F-9-fluoropropyl-(+)-dihydrotetrabenazine ( 18 F-AV-133) is a novel positron emission tomography tracer for imaging the vesicular monoamine transporter II in dopaminergic neuron degeneration, which might be indicative for Parkinson's disease (PD) and other parkinsonism. Studies were performed to optimize the imaging time window for calculating standardized uptake value ratio (SUVR) with correlation to distribution volume ratio (DVR) and in differentiating PD from normal controls (NCs). Methods: Thirteen 18 F-AV-133 positron emission tomography studies were conducted on four NCs (age, 62.3±4.9 years) and nine PD patients (age, 60.8±6.0 years) with Hoehn and Yahr stages 2 to 3. Dynamic images were acquired within 180 min (0–30, 50–140 and 160–180 min) and were rearranged into 14 of 10-min scans. The contralateral striatum was defined as the opposite striatum to the predominantly affected limbs. Volumes of interest (VOIs) of bilateral putamen, caudate nuclei and occipital cortex (OC; as the reference region) were delineated from individual magnetic resonance imaging. SUVRs of striatum to OC were computed from 14 dynamic image sets. The DVRs were computed from Logan graphic analysis by using OC as the input. The performance of SUVR was evaluated based on the correlation of SUVR at each time window to DVR, as well as the Cohen effect size (group mean SUVR difference between PD and NC/standard deviation). Results: 18 F-AV-133 uptake decreased in PD subjects at bilateral striatum especially at contralateral side with posterior putamen predominant as compared with NC. Consistent higher correlations of SUVRs to DVR for all VOIs were observed at later time window and reached to its maximal value of 0.9917 at 90–100 min. The group mean SUVR differences between NC and PD subjects increased and reached relatively stable values after 90 min. The effect sizes for all VOIs were stable across different time window and with the largest value around 90∼120 min

    Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected heart failure patients. However, not all patients respond to CRT. We hypothesized that a novel measure of electrical dyssynchrony, sum absolute QRST integral (SAI QRST), predicts CRT response independent of QRS duration and morphology. We retrospectively analyzed baseline 12-lead electrocardiograms of SmartDelay Determined AV Optimization: A comparison to other AV delay methods used in cardiac resynchronization therapy (SMART-AV) trial study participants (N = 234; mean age 67 years; 163 (70%) men; 140 (60%) ischemic cardiomyopathy; mean left ventricular ejection fraction 25%; mean QRS duration 152 ms; 179 (77%) had left bundle branch block). Baseline pre-implant electrocardiograms were digitized, transformed into orthogonal XYZ, and analyzed automatically by customized MATLAB software. SAI QRST was measured as an averaged arithmetic sum of absolute areas under the QRST curve. Patients were followed prospectively 6 months after CRT-defibrillator implantation. Patients with a decrease in left ventricular end-systolic volume ≥15 mL after 6 months of CRT were considered responders. The logistic regression model was adjusted for age, sex, bundle branch block morphology, left ventricular ejection fraction, cardiomyopathy type, and QRS duration. Patients with the high mean SAI QRST (third tertile) had 2.5 times greater odds of response than those with the low mean SAI QRST (first tertile: odds ratio [OR] 2.5; 95% confidence interval [CI] 1.3-5.0; P = .010) and 1.9 times greater than the lower 2 tertiles combined (OR 1.9; 95% CI 1.1-3.5; P = .03). Adjustment for renal function (OR 2.33; 95% CI 1.32-4.11; P = .003) and left ventricular lead position in right anterior oblique and left anterior oblique views (OR 1.7; 95% CI 0.9-3.2; P = .087) did not attenuate association of SAI QRST with outcome. High SAI QRST independently predicts CRT response in the SMART-AV study. Copyright © 2015

    The petroleum sector is highly significant for the Norwegian economy. Its share of gross domestic product, exports and total government revenues has been substantial over the past two decades, reaching a particularly high level in 2000 and 2001. The principal reason why revenues were so high in these two years is a combination of high oil prices, a strong USD against the NOK and historically high petroleum production. The share of petroleum investment in total capital spending in the Norwegian economy was at its highest in the early 1990s. Total investment in the petroleum sector has been above NOK 40 bn every year since 1992, and peaked in 1998 at roughly NOK 80 bn. Capital spending declined to around NOK 56.9 bn in 2001. The government's most important revenue sources in recent years have been cash flow from the state's direct financial interest (SDFI) and from taxes. Production of crude oil has averaged around three mill barrels per day since 1996. The figure for 2001 was 3.1 mill barrels. Including natural gas liquids (NGL) and condensate raises the 2001 average to 3.4 mill barrels oe per day. At 53 mill scm oe, gas production was also high in 2001. Oil production is expected to remain more or less unchanged over the next few years, and then to go into a gradual decline. Gas output, on the other hand, should expand substantially over the coming decade and is expected to be increasingly significant in Norwegian petroleum output in future. The petroleum sector is also a substantial player internationally. Norway ranks as the world's sixth largest producer and third largest net exporter of oil. It is also the world's third largest exporter of pipeline gas, and Norwegian foreign sales of this commodity accounted for about two per cent of global consumption in 2001. Roughly 10 per cent of west European gas consumption is covered from Norway. Several changes were made to state participation in the petroleum sector during 2001. The government sold 15 per cent of the state's direct financial interest (SDFI) to Statoil, which was also partially privatised. A further 6.5 per cent of the SDFI portfolio was sold in 2002. In connection with the partial privatisation of Statoil, two new state owned companies were also established. Petoro will manage the SDFI portfolio, while Gassco is a transport company for natural gas.
