    In this project experiences from combustion of animal and vegetable based liquid waste products have been compiled. Legal aspects have also been taken into consideration and the potential for this type of fuel on the Swedish energy market has been evaluated. Today the supply of animal and vegetable based liquid waste products for energy production in Sweden is limited. The total production of animal based liquid fat is about 10,000 tonnes annually. The animal based liquid waste products origin mainly from the manufacturing of meat and bone meal. Since meat and bone meal has been banned from use in animal feeds it is possible that the amount of animal based liquid fat will decrease. The vegetable based liquid waste products that are produced in the processing of vegetable fats are today used mainly for internal energy production. This result in limited availability on the commercial market. The potential for import of animal and vegetable based liquid waste products is estimated to be relatively large since the production of this type of waste products is larger in many other countries compared to Sweden. Vegetable oils that are used as food or raw material in industries could also be imported for combustion, but this is not reasonable today since the energy prices are relatively low. Restrictions allow import of SRM exclusively from Denmark. This is today the only limit for increased imports of animal based liquid fat. The restrictions for handle and combustion of animal and vegetable based liquid waste products are partly unclear since this is covered in several regulations that are not easy to interpret. The new directive for combustion of waste (2000/76/EG) is valid for animal based waste products but not for cadaver or vegetable based waste products from provisions industries. This study has shown that more than 27,400 tonnes of animal based liquid waste products and about 6,000 tonnes of vegetable based liquid waste products were used for combustion in Sweden to produce energy during the year 2001/2002. The operation experiences are in general good but some problems have occurred, for example both Extraco and Karlshamns AB have had fouling problems in the boilers and high emission levels of NO{sub x}. Other operation problems are for example corrosion and wear on the fuel supply system, problems with water in the fuel, increased wear on valves and pumps, plugged nozzles and valves and a plugged economizer. The German company SAACKE has since 1993 installed 26 plants for combustion of animal fats in liquid form in several European countries. The operation experiences from these plants have been used for development of the advanced combustion technology. When it comes to logistics liquid animal and vegetable based fats need to be kept warm during transportations and storage. This does not result in any large problems suitable equipment already is in use for heavy fuel oil.

    Täby kommun har sommaren 2013 infört en för Sverige ny dagvattenreningsteknik i form av en flytande våtmark, som har anlagts i Rönningesjön. Tekniken kan förklaras som en hybrid, där de biologiska reningsprocesserna liknar en naturlig våtmark, medan anläggningen hydrologiskt fungerar mer som en sedimentationsdamm. Att våtmarken är den första i Sverige gör det extra intressant att utvärdera. I och med denna rapport har dels en specifik undersökning av anläggningen gjorts, med ...

    The aim of this project was to increase the understanding of opportunities and problems connected with combustion of sorted waste fractions containing paper, wood and plastics (PWP-fuel) in fluidized bed boilers. An evaluation of the effect of sulphur containing additives in a PWP-fuel fired boiler was also performed within the project since this is not previously reported in open literature. The experience from two boilers at different plants, Johannes (BFB) and Hoegdalen P6 (CFB) during the firing season 2003/2004 was documented. In the Johannes boiler the main fuel is bark while Hoegdalen P6 combusts 100 % PWP-fuel. Analysis of the fuels shows that there are large differences between the two boilers. At Johannes the PWP-fuel contained low amounts of elements (chlorine, alkali and other metals) that are expected to result in increased operational problems or emissions. A large proportion of these unwanted elements came from the wood and paper fractions. The plastic fraction in Johannes had very low levels of unwanted elements. The fuel at Hoegdalen contained large amounts of elements such as chlorine, alkali and other metals that can cause operational problems. First of all the plastic fraction contained large amounts of chlorine, most likely from PVC, which results in a more corrosive atmosphere in the boiler. The fraction of fines in the Hoegdalen fuel contained larger concentrations of potassium and sodium compared with the other fuel fractions, substances that also are related to the formation of deposits. The fraction of fines in the fuel probably also results in combustion taking place high up in the boiler and to some extent continuing in the cyclones. The characterisation of the combustion behaviour performed in Johannes identified a maldistribution in O{sub 2}, CO and gas temperature over a cross-section of the furnace. This was not depending on the fuel mixture but is more likely depending on uneven fuel feeding or air distribution. A comparison between the different fuel mixtures shows that addition of PWP-fuel results in locally lower O{sub 2}-levels and higher CO-levels close to the front wall. This results in an increased risk for local corrosion on the furnace walls. The measurements in Johannes showed that co-combustion with PWP increased the alkali chloride concentration in the flue gas but an increase in the amount of deposits could not be measured. However, the deposits contained more chlorine during co-combustion of PWP, which should yield increased risk for corrosion. The increase can be correlated with the wood and paper fractions of the fuel. Injection of sulphate in the furnace resulted in increased SO{sub 2} concentration and reduced alkali chloride concentration, which resulted in reduced deposit formation. Addition of sulphate also reduced the chlorine concentration in the deposits thereby reducing the corrosion risk. The sub micron particles in the flue gas before gas cleaning mainly contain KCl and K2SO{sub 4} but with sulphate addition KCl to a large extent is converted to K{sub 2}SO{sub 4}. Altogether, this shows that this kind of fuel yields an increased risk for corrosion and deposits on superheaters and furnace walls. However, these problems can to a large extent be avoided by the addition of sulphur (concerning superheater corrosion) and adjustment of the air and fuel feed equipment (concerning furnace wall corrosion). Also in the tests in Hoegdalen the SO{sub 2} concentration increased and the alkali chloride concentration decreased in the flue gas when sulphur was added, resulting in decreased deposit formation. At the same time the chlorine concentration decreased and the sulphur concentration increased in the deposits. However, the chlorine concentration of the deposits was still high and did not decrease as much as in Johannes. Using elementary sulphur or sulphate as an additive had no noticeable influence on deposit growth or on the chemical composition of the deposits. Neither did the measurements show that sulphur containing additives decrease the corrosion rate during combust

    The results from this project show that phosphorous-rich additives could be of interest to reduce fouling and high temperature corrosion without causing increase in slagging and/or bed agglomeration tendency for typical biofuels. General results in this series of experiments show that in order to achieve a good potassium-binding effect the calcium and magnesium content should be low in the phosphorous-rich fuel and additive. If the content of Ca and Mg is high in the final fuel mixture (including both P-fuel/additive and the bulk fuel) the K-binding effect is reduced and more P needs to be added. Of course, this also means that the additive of choice (fuel or chemical) should have a low content of calcium and magnesium. It is therefore probable that the best results will be obtained when using a fuel mix where the final blend has a molar ratio of P/(K+Na+2/3Ca+2/3Mg) approaching 1. For instance, using monoammonium phosphate, this would be equivalent to a cost (autumn 2009) of about 9-14, 10-15 and 30-40 SEK in P-additive cost per MWh of added fuel to achieve this molar ratio for typical logging residue, salix and wheat straw biofuels.

    District heating owners have been offered quantities of manure for combustion. Race tracks and riding schools have surplus amounts and could be the major suppliers. The question among district heating plant owners has been `is it suitable to use the manure as a fuel or not`? The conclusion is that there are in general no technical problems to burn the manure with high efficiency and low emissions if modern technology is used. There are however secondary problems which must be considered. The main problem is the risk of very low ash softening/melting temperatures. A second problem is the high sulphur and chloride levels that can be found in manure, which can give serious corrosion problems. It can therefore be concluded that one should not use pure manure in existing district heating plants designed for wood fuels. Manure is more suited for waste plants designed for sintering and corrosive fuels. There is however a risk of increased NO{sub x} emissions. Cofiring with wood fuel is however a possibility in existing wood bio fired plants, especially if the economic benefit is high. The properties of wood fuel together with minor quantities of manure could minimize the risk of sintering and corrosion. Manure is however a very heterogeneous product and it could not in general be recommended to use manure without having it analyzed and without having knowledge of the plant. 20 refs, 11 tabs

    Reduction of emissions of carbon monoxide and organic substances by injecting either ammonium sulphate or elemental sulphur and the importance of the point of injection has been investigated in full scale in a grate-fired bark boiler. The effect was monitored downstream of the economizer and air preheater, immediately upstream of the electrostatic precipitator. Concentrations determined in the comprehensive monitoring program include principally carbon monoxide, TOC and several organic substances, including PAH, PCDD/F and polychlorinated benzenes (PCBz). Additionally, the gaseous PAH were determined on-line using a novel mass spectrometer, REMPI-TOF MS, that measures specifically the 2- to 4-ring PAH's. All concentrations of substances of interest here fluctuate in concert and peak simultaneously. The relationship between the concentrations is not straightforward: there appears to be a threshold in carbon monoxide concentration. Below this threshold, the concentration of organics is low and above it concentrations increase rapidly with increasing carbon monoxide concentration. It has been confirmed that using sulphur additives not only reduces the concentration of carbon monoxide, but also that of organic substances in the flue gases. These additives do not only reduce the mean level of concentrations, but also dampen the fluctuations in these concentrations. Any measure leading to a reduction in carbon monoxide will also decrease the concentration of most organics, under the conditions prevalent in this boiler. Both additives tested are equally effective per kg of pure sulphur. The point of injection, in the fuel or above the grate, is not important. The PCDD/F concentration in the flue gases is very low even without additives, and the effect of sulphur on these emissions is therefore difficult to observe. Here, the effect is masked by the variation of data. The PAH concentration is lowered by an injection of sulphur additives. The variation in data is though rather large, which may be caused by variation in particle content in the gas samples

    The background to this project is the new EU directive 2000/76/EG regarding incineration of waste. This directive may have an effect on emission limits for Swedish plants firing waste wood. It may lead to needs of refurbishment in e.g. the area of flue gas cleaning equipment. In order to produce a basis to evaluate the need for such upgrading, measurement of metals, HCI, SO{sub 2} , CO, TOC and dioxin have been carried out on three plants firing wood waste: a grate boiler (Handeloeverket P11), one circulating fluid bed boiler (Aaterbruket in Lomma), and a bubbling fluidised bed boiler (Johannes in Gaevle, firing 50% waste wood). The measurements have mainly been carried out after boiler, equivalent to upstream flue gas cleaning. The results are that the demands of the EU directive on most points can be managed with existing equipment if this consists of electrostatic precipitator or bag filter with good performance and flue gas condensor. Without flue gas condensor, there is a need for other measures for 1-10 and for grate boilers, SO{sub 2} as well. The requirements in the directive for TOC is weaker than the demand on CO, and correspondingly, the demand on CO is driving. The level of dioxin from the boiler (upstream filter) exceeds allowed emission, and is in the range of 0,1-2 ng TE/Nm{sup 3} tg, 6 % O{sub 2} . Existing equipment will meet the emission limit for the lower levels (0,1-0,3) , but not safely for the higher levels (1,5-2). Correspondingly, there may be a need for equipment upgrading, e.g. in the form of activated carbon injection upstream flue gas filter.

    The conversion potential to replace oil in the energy intensive industries and diesel in heavy transport is estimated in the study to 6.8 TWh and 10 TWh per year, respectively. Several alternative fuels compete for this conversion potential. What fuels will take market share depends on several factors such as price, availability of fuel, availability of process technology and vehicles, technology development and possible future technological advances. For liquid methane to compete a new infrastructure is required that in a cost effective manner makes it possible to distribute the liquid methane to the regions where the need is the greatest. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. The study points out three nodes, Gaevle, Sundsvall and Luleaa, which is suitable for distribution of liquid methane to the central and northern Sweden. The three hubs are suitable for freight transfer to trucks as well as rail and shipping. A strategic nationwide network of refueling stations is also proposed, with a total of 18 new stations, in addition to the filling stations in southern and central Sweden that are already planned or in operation. Both the availability and use of liquid methane in Sweden today is limited. Liquid natural gas, LNG (liquefied natural gas), is primarily used as a backup to biogas plants, in a few industries and as supply for a few filling stations for compressed gas. The availability of LNG and also liquid biogas (LBG liquefied biogas), will increase in coming years. In 2011, two new LNG import terminals are put into operation in Nynaeshamn and Fredrikstad in Norway and two additional import terminals are planned in Gothenburg and Lysekil. Furthermore, two production plants for liquid biogas production have started, and four additional plants are planned, which together will produce around 0.5 TWh LBG annually. It is also likely that in the coming years there will be almost ten filling stations for liquid methane in operation in southern Sweden. The market analysis shows that several industries in the iron and steel industry are already interested in converting to LNG, mainly to cope with environmental demands. Also in the chemical industry there is an interest in using LNG, while many of the companies in the pulp and paper industry do not see LNG as a particularly attractive option. The latter have access to their own fuel and several companies have also adopted policies aiming at becoming fossil fuel free in the near future. The total conversion potential to replace oil with LNG industry amounted to 6.8 TWh/year, divided among 100 users. The greatest potential is in central Sweden (Dalarna, Gaevleborg, Vaermland) and along the Norrland coast. With today's distribution system, including truck delivery from import terminals in Nynaeshamn and Fredrikstad, virtually the entire southern Sweden is within reach of LNG deliveries. Transport distance is too long to be economically feasible to supply industries in central and northern Sweden. To provide these regions with LNG the intermodal freight terminals in Gaevle, Sundsvall and Luleaa would be able to function as strategic hubs. These three terminals covering the areas and industries that according to the market analysis is most interesting for LNG supplies, and are all well connected both by road, rail and seaway, allowing for transfer between different modes. All harbours also have the potential to qualify for receiving LNG deliveries by ship. There is also an interest in using liquid methane for heavy transport and coaches/intercity buses, because the distribution of liquid methane is cost effective, and the vehicles get longer range due to the high energy density of liquid methane. Yet, however, the availability of vehicles is limited and the infrastructure is not developed, but both the availability of vehicles and refueling stations will increase in coming years. In total, about 10 TWh/year of diesel needs to be replaced i n the heavy vehicle sector, among other reasons to meet environmental goals, which is assumed to correspond to the conversion potential in the heavy duty vehicle sector in the long term (2030). A rough estimate of the possible development means that the demand for biomethane, in the form of LBG, and CBG (compressed biogas), by 2020 will amount to 1.5 TWh/year for heavy duty transport applications and to about 1 TWh/year LNG for long-range heavy duty transport. Furthermore, it is estimated to be possible that the production capacity of LBG double by 2020, reaching around 1 TWh/year.

    This study has provided an initial picture of where the most interesting ports and areas available for future expansion of a maritime infrastructure for LNG. On the basis of supplying vessels with LNG as fuel, from a long term perspective, we recommend locating LNG terminals in or near major ports and around the big ship routes. Given the current age distribution of ships operating waters of the Baltic Sea, almost 20% of the vessels are 30-40 years old and likely to be replaced by 2015 - 2020. Thus, there is a potential for newly built ships will be equipped with LNG operation. Selected criteria s; Size of the LNG terminal and hence the need for the size of the fairway and the area of land. Proximity to traffic routes with much ship traffic. Proximity to the major port. Proximity to consumers on the land side. On the basis of selected criteria and analyzed for possible location of the terminal it can be noted that a number of Swedish ports are found suitable. For example, ports of Sundsvall, Gothenburg and Helsingborg has been identified as suitable, but with different starting point and different types and sizes of terminals possible.

    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.

    Different types of sludge containing organic material are produced within the pulp and paper industry (fibre sludge, sludge from production of recycled fibres, de-inking sludge, chemical sludge, bio sludge etc). The newly introduced tax on waste deposition, 250 SEK/tonne wet material, has together with the coming law against disposal of different organic material raised the interest for minimising the sludge deposition. The moisture content of the sludge depends on the type of sludge and type of dewatering equipment used. The moisture content is however normally so high that a main part of the theoretical energy content is used for evaporating the water in the sludge. The sludge is successfully destroyed and the amount of sludge being disposed is reduced but there is very little net energy contribution from the sludge firing. An increased dry substance content would considerable reduce handling problems and problems connected with combustion of wet sludge. The energy yield would also increase and instead of destroying a wet waste material useful energy would be generated. One alternative for reducing the problems with wet sludge would therefore be to dry it to a suitable moisture content and then fire the dried sludge in a grate boiler, a fluidized bed boiler, a pulverised fuel boiler or in a pellet burner. In this project the alternative to dry the sludge and produce pellets with a moisture content of about 10 % is covered. The costs for upgrading wet sludge to dry pellets have been estimated in the report. Laboratory studies have also been carried with two different sludge samples to have a first indication of the results from firing sludge pellets in a pellet burner. The results from the project together with experiences from an earlier Vaermeforsk project shows that every sludge in principal is unique meaning that the composition depends on the production situation at the different specific plants. The ash content as well as the ash composition and the moisture content going into the sludge dryer varies from case to case. If one however looks at sludge from a more general point of view one will find that the ash and moisture free substance has more or less the same elementary composition, and thereby also effective heat value, as wood pellets. The experiences from the two sludge samples tested in the project showed that there were difficulties when trying to fire only sludge in the pellet burner. The difficulties were connected to the high ash content and for one of the sludge samples also to the low sinter temperature. Good combustion conditions could however be maintained when firing 10-20 % sludge pellets together with wood pellets. Higher nitrogen and sulphur content compared to wood resulted in increased emissions of SO{sub 2} and NO{sub x} for both of the sludge samples. A reasonable mixture between sludge and wood pellets based on these emission levels will be about 5 to 10 % if no flue gas cleaning is used. More sludge would mean that flue gas cleaning would be necessary both regarding to SO{sub 2} and NO{sub x} . Dried sludge should regarded as a very good fuel but one has to be prepared to handle: More ash; Risk for sinter problems; Risk for increased emissions of SO{sub 2} and NO{sub x} (and possibly HCl)

    Full Text Available Ved planlegging av offentlige bygninger i Norge forutsettes det at brukerne medvirker i prosessen. Dette er forankret i lov- og avtaleverk og motiveres ved at brukerne innehar en kompetanse som er av betydning for byggenes funksjonalitet. I denne artikkelen vil jeg belyse brukermedvirkningsproblematikk i planleggingen av et skoleanlegg for videregående opplæring. Tilgjengelige plan- og byggesaksdokumenter i den aktuelle fylkeskommunens digitale og fysiske arkiver er blitt analysert. I referater fra brukermøtene fremmes det for eksempel ønsker fra brukerne om begrenset bruk av glass. Det ferdige skole-anlegget har imidlertid utstrakt bruk av innvendige glassvegger, men det er ikke dokumentert diskusjoner knyttet til bestemmelsen av dette. Et profesjons- og maktperspektiv er relevant for å forstå hva som blir verdsatt, og hvilke strukt-urer og mekanismer som har påvirket planleggings­prosessen. De sentrale aktørgruppene er skoleeier og representantene for lærer- og arkitekt-profesjonen. Omfattende bruk av innvendig glass i skoleanlegget tolker jeg som et kompromiss mellom skoleeiers ønske om åpenhet og kontroll, lærernes ønske om mindre støy og arkitektens ønske om å skape romfølelse og visuelle siktlinjer.AbstractWhen planning public buildings in Norway, it is expected that users are involved in the process. This is grounded in legislation and agreements, and motivated by the idea that users have an expertise which is significant for the planning of the building’s functionality. The aim of this article is to investigate user participation in planning the school facilities for a secondary school. I have analyzed planning and building documents available in government records, digital and physical. In the reports from meetings with user groups, it is for example stated that users want to limit the use of glass. However, the completed school building has extensive use of glass dividing walls, but any discussions leading to this

  17. AV dissociation, an inevitable response.

    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.

  1. Effects of kaolin-additions in combustion of wood fuels on hardening and leaching properties of ash; Paaverkan av kaolintillsats vid foerbraenning av biobraensle paa askans haerdnings- och lakningsegenskaper

    In several investigations it has been shown that kaolin works well as an anti-agglomerating and anti-ash sintering agent in combustion of bio-fuels with a potassium rich ash in fluidised bed boilers. Combustion tests have shown that the kaolin addition may result in an ash melting temperature that is a couple of hundred degrees centigrade higher than for the original ash. This way the kaolin hinders the fouling of super heater surfaces by sticky ash. Many boiler owners treat their wood fuel ash with the aim to recycle it to forest soil as a nutrient source and acid neutralising agent. Therefore it was considered important to investigate if an addition of kaolin in the boiler would have a negative influence on the ash leaching properties. Thus, the aim of the project was to investigate the hardening reactions and leaching properties of normal wood ash and wood ash produced with addition of kaolin. The ash samples were produced in the same boiler and in similar combustion conditions. It was especially interesting to study if the ash would contain soluble aluminium due to the kaolin addition since aluminium in solution may have negative effects on the eco system. The results showed that an important difference between the normal fly ash and the fly ash with kaolin was that the release of potassium i leaching was decreased due to the kaolin addition, especially at high pH levels. This is positive, since potassium normally is released very fast in the forest. In addition, the kaolin containing ash has a faster initial setting/hardening process than the normal ash. The structure of the hardened ash particles is also more durable than that of the normal ash. This is also a positive effect since it indicates that it could be possible to handle the hardened ash after a shorter storage period. However, it has not been investigated if this effect remains in large scale operation and in a longer time perspective. The acid neutralising capacity of fly ash with kaolin is, calculated per kg of ash, somewhat lower that for the usual ash. The kaolin is accumulated in the fly ash since it has such a small particle size and thus dilutes the fly ash and lowers its content of acid neutralising components. This can be compensated for by spreading more ash per hectare. The leaching of aluminium from the kaolin containing ash was low at all pH levels studied (4- 13). Consequently, spreading of such an ash is not considered to pose any risk for the environment. In addition, the leaching of trace metals from the ash was not affected negatively by kaolin addition

    During combustion of fossil fuels, SO{sub 2} is released to the atmosphere. Because of environmental concern with acid rain, the capture of SO{sub 2} is a very important process. Fluidized bed combustion (FBC) is a combustion method where limestone may be added to the furnace chamber to capture SO{sub 2} as the stable product CaSO{sub 4}. In the present work a relatively simple laboratory method has been developed for characterizing limestone reactivity with SO{sub 2}. The reactivity data from such investigations are used, together with residence time and particle size distribution, in a sulfur capture model for fluidized bed boilers that predicts the sulfur capture as a function of the Ca/S molar ratio. In addition, the model predicts the conversion of CaO to CaSO{sub 4} for all particle sizes present in a boiler. The model was developed and verified using data from two boilers, a 12 and a 40 MW circulating fluidized bed boiler, and showed reasonable agreement for both boilers. In addition to the development of a sulfur capture model, the effects of SO{sub 2} and CO{sub 2} concentrations, particle size, temperature variations, and reducing conditions on the sulfation reaction was studied using a fixed-bed quartz reactor. The sulfation reaction was also studied for long periods of time, up to 60 hours. This was done because of the long residence times of certain particle sizes that may exist in a fluidized bed boiler. From the parameter study it was found that particle size and variations between oxidizing and reducing conditions had a large effect on the sulfation behaviour. The investigation of long sulfation times showed that the reaction continued even at high degrees of conversion, although at a very slow rate. CO{sub 2} concentration had a moderate effect on the sulfation reaction while temperature variations showed no effect on the final conversion between CaO and CaSO{sub 4}. 29 refs, 25 figs, 4 tabs

    The purpose of this project was to investigate the effects of incineration of biological sludge in the recovery boiler of a Swedish Kraft pulp mill, StoraEnso Pulp AB Skutskaers Bruk, which has practiced incineration of sludge in the recovery boiler during the last two years. The following aspects of the technique were investigated: Experience from operation of incineration of biological sludge in the recovery boiler; The content of Non-Process Elements (NPE) in process flows and evaluate the risks of incrustations in the system; The build-up of NPE in the chemicals recovery system and the estimated increase in make-up lime demand; and Technical risks for mills with different process equipment. This study comprises the following NPE: aluminium, silicon, phosphorus, magnesium, calcium, chloride, iron, manganese, potassium, copper, and nitrogen. The operational experience from the system for hydrolysis of the biological sludge and evaporation/incineration in the recovery boiler is excellent. The handling of the sludge takes place in a closed system that demands little supervision and maintenance. Overall, the mill has not seen any negative effects that can be explained by increased intake of NPEs to the chemical recovery system. Aluminium can lead to troublesome incrustations of sodium-aluminium-silicates on the heat surfaces in the evaporation plant. An effective elimination of aluminium by the green liquor dreg is obtained with the double salt hydrotalcite if the quotient Mg/Al is kept higher than 4-5 in the black liquor. The need for make-up lime has increased due to the build-up of phosphorus in the lime. Depending on the level of make-up lime the need will increase 2-5 kg/ t{sub 90} at a price of 2-5 kr/t{sub 90}. If a higher level of phosphorus is accepted instead of increasing lime make-up the running costs will be somewhat higher, 0,5-1 kr/t{sub 90} due to increased ballast. NO{sub x} in the flue gases from the recovery boiler has not increased since the start-up of incineration of biological sludge in the recovery boiler. A possible explanation may be that the nitrogen in the biological sludge exists in a state that gives less formation of NO{sub x} compared to nitrogen in the black liquor. For the other NPE as silicon, magnesium, calcium, chloride, iron, manganese, potassium and copper the contribution from the sludge is low. It will not give any problems for the chemical recovery system at Skutskaer. Integrated pulp and paper mills with or without recycled paper use and coating with calcium carbonate and/or kaolin will probably have increased difficulties to incinerate biological sludge in the recovery boiler. The production of paper in addition to the pulp production will generate higher amounts of biological sludge also will contain higher content of calcium, aluminium and silica and possibly other NPE from the recycled paper.

    The aim of this project is to evaluate how the operation conditions and the combustion chemistry is changed in a Bubbling Fluidized Bed (BFB) Boiler when adding approx. 20 wt-% Biomal into the fuel mixture. The following issues were addressed in the project: 1. How does the new chemical composition of the fuel mix influence bed agglomeration, deposit growth, ash flows, flue gases and particle size distribution? 2. Is it possible to run the boiler at a reduced bed temperature of about 750 deg C due to the increased moisture content originating from the biomal fuel? The project is based on combustion tests in the two Waste to Energy boilers at 20 MWth each owned by Boraas Energy and Environment AB (BEM). Furthermore, results from the Waste Refinery Project 'Reduced bed temperature in FB-boilers burning waste - part II' has been used as reference in some cases. At normal conditions the boilers are run on a fuel mixture containing 80 % sorted industrial waste and 20 % household waste. This fuel mixture consists mainly of paper, plastics and wood. In Boraas the organic part of the household waste is sorted out and used for biogas production. With the addition of biomal, which consists of animal by-products crushed to a pumpable fuel, the chemical composition of the fuel mixture is changed to some extent. The results from the combustion tests shows that biomal influences the chemical fuel composition, but also that there are large variations in the ordinary waste fuel composition as well. The most evident changes with addition of biomal are: 1. Increased moisture. 2. Reduced heat value. 3. Increased amount nitrogen, calcium and phosphorus. 4. Decreased amount lead due to the low concentration in biomal. However, there were no changes in sodium, potassium, sulphur and chlorine, elements important for increased/reduced fuel related problems, derived from biomal. The increase of calcium and phosphorus with biomal derive from bone and the calcium-phosphates influenced to some extent the sand/ash flows were the largest change was an increase in the amount of phosphorus and calcium. In addition a decrease of the amount of lead was seen in all ash flows. The calcium-phosphates were stable during combustion and no reactions of phosphorus with other elements were detected. The results from the trials in this project show that co-combustion of biomal had the following positive effects on the boiler performance: 1. The bottom bed temperature decreased, but > 20 % biomal is needed to reach 750 deg C. 2. The risk for bed agglomeration was decreased. 3. The NO{sub x} emission was reduced at the same time as the addition of ammonia was reduced. 4. The deposition rate of the deposits collected on the test probe was reduced, thus no increased risk in deposit formation on the superheater tubes. The conclusion is that the boiler could be operated in a safe way with addition of biomal.

    The main objectives of this study were to identify and calculate the additional costs to energy plants of combustion of agro fuels instead of wood chips, and to determine the potential farmers have to influence fuel quality and thus identify parameters that could be used for pricing in the future. The overall aim is to increase the volume of agro fuels produced. Four agro fuels were considered in this study: willow, straw, husks and reed canary grass. These four were selected because data were available on their combustion at energy plants and because they are representative of different categories of agro fuels: short rotation coppice, crop by-products, seeds and grass. Data were obtained through literature surveys, telephone interviews with farmers, researchers, advisors and contractors, and visits to six energy plants. Combustion properties for each crop and data on combustion were compared. Measures that could be taken by farmers to improve fuel quality today and perhaps in the future were estimated. Although information and experience proved to be lacking in this area, it was possible to identify some potential measures, which are listed below for each fuel. To promote expansion of the agro fuel market, issues concerning business contacts and forms of organisation were examined. The choices and preferences of farmers as regards sale and delivery are influenced by a number of different factors, which were investigated here by studies of the literature and interviews with farmers. There was little documentary evidence available on combustion of agro fuels. Short-term trials have been carried out on small amounts of a number of crop species without specific documentation of emissions, maintenance costs, ash handling, etc. The additional costs to energy plants for combustion of agro fuels compared with wood chips were investigated on visits to energy plants by collecting data directly and by interviewing plant personnel. The additional costs were then calculated for each fuel and type of boiler, but the specific conditions prevailing in any individual plant will obviously affect the actual costs. General conclusions were: Additional costs for an outage caused by the agro fuel depend on whether there is an accumulator to cover some of the load, and on the other types of boilers and equipment available. Additional costs for ash handling depend on the technical system and business agreements concerning ash handling, which differed between the energy plants visited. Additional costs arising when a boiler and/or fuel is new can be reduced by hard work and experience. In one example (Saatenaes), feeding a new boiler with new straw with a moisture content of 20-22% caused problems with fuel feeding, more frequent soot blowing, etc. Through persistent efforts and feedback on straw quality to farmers, these problems have been eliminated. In two cases, 100% agro fuel was combusted during part load periods. In one case full load could not be achieved because of low bulk density and resulting limitations of the feeding system, and in the other case high load was known to cause problems with fouling and dust production. Using agro fuels during part load was not considered an additional cost. At the two combined heat and power plants (CHP-plants) visited, the upper limit for willow in the fuel mix was set at 15%, since additional costs caused by increased fouling are expected beyond this level (based on experience). This study has mainly focused on the cost for a plant to change from forestry fuels to agro fuels. However, a more common issue is to co-combust a cheaper fuel. This is especially true for larger boilers mainly due to the fact that the fuel availability is more uncertain if large quantities of agro fuels shall be used, and that problems like increased deposit or corrosion rate shall be avoided. Therefore this investigation has looked both at cases with combustion of 100 % agro crops (Jordbro, Kvaenum, Graestorp and Saatenaes) and at cases with co-combustion (Enkoeping and Eskilstuna). Co-combustion of agro fuels with another fuel can reduce the problems that might arise due to the fuel properties of the agro fuels, and has therefore an influence on the rate of extra costs. To increase the market for agro fuels, there is a need for: Information to farmers about existing crops and potential buyers. Initiatives from the energy companies are desirable. Tangible information to suppliers on the structure of the whole chain and the need to grow and deliver consistent amounts. Contract forms that give farmers an acceptable risk. A dialogue between farmers and the energy companies concerning the quality changes that can be achieved by decisions at harvest, storage, transport and price-setting, etc

    Agricultural derived solid fuels are more problematic to combust in small-scale heating plants than conventional wood fuels. Their high content of ash, chlorine and sulphur leads to increased emissions of dust, sulphur dioxide and hydrogen chloride in the flue gases. By transporting the flue gases to a flue gas well where it condenses, and separates dust and sour components, enables a cost effective flue gas purification for small-scale heating plants (50 kW - 10 MW) of agricultural derived solid fuels. This project have studied two heating plants using flue gas wells with the aim to add to the knowledge about how a flue gas wells may look like and to quantify how much emissions of dust, chlorine and sulphur in the flue gases are reduced. The project also aimed to summon regulations and laws regarding the handling of the condensate that develop in the flue gas well. In the project measures were conducted on two different heating plants with mounted flue gas wells: a 60 kW biofuels boiler combusting grains and red canary grass and a 1 MW batch fired boiler combusting wheat straw. Measurements on flue gases were conducted with and without water injection in the flue gases. The flue gas wells reduced dust emissions of up to 80 %. The best reduction was achieved at the 60 kW heating plant when firing red canary grass. Firing grains in the same plant lead to 7 % reduction of the dust emissions. In the 1 MW heating plant firing wheat straw the flue gas well accomplished 40 % reduction of dust emissions. The boiler ability to achieve complete combustion, hence minimize the content of volatile and semi-volatile components in the flue gas, is largely affecting the flue gas well ability to reduce dust emissions. This did not, however, affect the reduction of dust in the flue. Chlorine emissions was reduced by up to 88 % by a flue gas well. Water injection made a big difference on reduction of chlorine emission from grain combustion. Sulphur emissions was reduced by 50 %, from wheat straw combustion, by a flue gas well. No reduction of sulphur was achieved from grains combustion in the 60 kW heating plant and water injection had little or no effect on the reduction rate. As the condensate was very acetic and potentially erosive an ejector fan was used to cool down the flue gases enough to enable acid resilient plastic pipes to be used for the flue gas canal. The well was drained of condensate continuously and the piping must be sweeped with regular intervals to prevent blockage of the flue gas. Plants below 20 MW is excluded from national regulations on activity emission regarding flue gas condensate. The Swedish Environmental Code does however place the responsibility for preventing harm to nature upon the practicer. The possibilities of managing the condensate from the flue gas well are spillage to a manure reservoir for spreading it as fertilization on farmland, or spillage directly to receiving waters. The later method require neutralization of the pH, commonly by using sodium hydroxide, but possibly also limestone

Ultralydmåling av fosterets størrelse og biometriske referansetabeller for svangerskapet brukes til å fastsette svangerskapets alder, beregne termin og vurdere fosterets vekst. Optimal studiedesign er ulik for hvert av disse formålene. Det er stor variasjon i fysiologisk vekst og en utfordring å identifisere fostre som har dårlig tilvekst. En enkeltmåling av fosteret kan fortelle oss om det er lite eller stort i forhold til andre fostre, men ikke om størrelsen er passelig i forhold til forventet fysiologisk vekst for dette fosteret. Tilpassede referansemodeller ("customised" justerer forventet størrelse i relasjon til føtale og maternelle faktorer og har vist seg å bedre identifisere sanne veksthemmede fostre enn bare å klassifisere i henhold til 2,5, 5 eller 10 persentilen. Men et foster som i utgangspunktet er stort for alderen, men etter hvert vokser langsomt vil ikke nødvendigvis bli fanget opp ved en slik enkeltmåling.

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

    The market of forest products is expanding and thus resulting in more expensive biomass fuels. Therefore research within the combustion industry for alternative fuels is needed, for example cultivated fuels. Combustion and gasification research on these cultivated fuels are limited. The objectives of this work was to increase the general knowledge of silicon rich cultivated fuels by study the agglomeration characteristics for wheat straw, reed canary grass and industrial hemp in combination with commercial bed materials. Controlled fluidized bed agglomeration tests was conducted in a 5 kW, bench-scale, bubbling fluidized bed reactor. The tendencies of agglomeration were determined with the three cultivated fuels in combination with various minerals present in natural sand (quarts, plagioclase and potassium feldspar) and an alternative bed material (olivine). During the experiments bed samples and formed agglomerates were collected for further analyses with a scanning electron microscope (SEM) and with X-ray microanalysis (EDS). Wheat straw had the highest agglomeration tendency of the studied fuels followed by reed canary grass and industrial hemp. No significant layer formation was found around the different bed particles. Instead, the ash forming matter were found as individual ash sticky (partial melted) particles in the bed. The bed material mineralogical composition had no influence of the agglomeration process because of the non layer formation propensities of the used silicon rich fuels.

  4. Transmembrane potentials of canine AV junctional tissues.

    Science.gov (United States)

    Tse, W W

    1986-06-01

    The atrioventricular (AV) junction comprises the AV node, His bundle (HB), and specialized tissues proximal to the node called paranodal fibers (PNF). In the present study, an in vitro, dissection-exposed canine right atrial (RA), transitional fiber (TF), AV junctional preparation was used. The TF and PNF formed a pathway running along the base of the septal cusp of the tricuspid valve (SCTV). In the first experiment, impulses elicited at the RA were monitored to propagate sequentially through the TF, PNF, AV node, and then the HB. This functional evidence supports the concept that a conduction pathway connecting the RA and the AV node exists along the base of the SCTV. This internodal pathway is referred to as the septal cusp pathway. In another experiment, transmembrane potentials and Vmax were determined on each of the AV junctional tissues. Results showed that PNF had the lowest Vmax (2.5 V/sec), followed by AV node (7.0 V/sec) and HB (33 V/sec). This finding showed that PNF, and not the AV node, has the lowest Vmax, suggesting that the PNF has the lowest conductivity among the AV junctional tissues, and this study advances our understanding on the mechanism of AV conduction delay in dog hearts.

    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.

    Audio Video Coding Standard (AVS) is a second⁃generation source coding standard and the first standard for audio and video coding in China with independent intellectual property rights. Its performance has reached the international standard. Its coding efficiency is 2 to 3 times greater than that of MPEG⁃2. This technical solution is more simple, and it can greatly save channel resource. After more than ten years ’develop⁃ment, AVS has achieved great success. The latest version of the AVS audio coding standard is ongoing and mainly aims at the increasing demand for low bitrate and high quality audio services. The paper reviews the history and recent develop⁃ment of AVS audio coding standard in terms of basic fea⁃tures, key techniques and performance. Finally, the future de⁃velopment of AVS audio coding standard is discussed.

    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.

    2015-08-01

    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.

    Klimapolitikken bidrar til å fase ut termisk kraftproduksjon basert på fossile kilder. Dette kan føre til at en mindre andel av kraftproduksjonen kan respondere på prissignaler. Det er planlagt å øke andelen vindkraft i flere kraftmarkeder. Vindkraft er avhengig av været, og er karakterisert av varierende produksjon. Dette påvirker inntekten til hva produsenter av vindkraft vil tjene i kraftmarkedet. Studier har funnet at markedsverdien til vindkraft reduseres ved økte andeler vindkraft i ma...

  2. Forandring av selvoppfatning blant studenter i løpet av en bachelorutdanning i sykepleie

    Full Text Available Selvoppfatning er av betydning for faglig framgang og kreativitet. Hensikten med denne studien var å beskrive forandring av selvoppfatning hos en gruppe sykepleierstudenter i løpet av sin treårige bachelorutdanning. En studiegruppe med 127 sykepleierstudenter ved en norsk høgskole besvarte et spørreskjema i første og siste studieår. Skalaer for måling av generell selvoppfatning og regelbevissthet samt spørsmål om bakgrunnsvariabler inngikk i spørreskjemaet. Resultatene viste at selvoppfatningen økte signifikant i løpet av utdanningen i den totale studiegruppen, og viktige faktorer var barn og opplevelse av tilfredshet. For ca 45% av deltakerne var selvoppfatningen enten lavere eller uforandret. Regelbevissthet minket i løpet av utdanningen og var ikke assosiert til studentenes selvoppfatning. Fortsatt forskning behøves for å klarlegge mulige påvirkningsfaktorer og for å finne tiltak som kan fremme en positiv utvikling av selvoppfatning hos studenter.

  6. Arvelig hemokromatose - nytten av screening

    2009-10-01

    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.

    Event marketing är en marknadsföringsform som har växt ordentligt under senare delen av 90-talet och det börjar bli ett naturligt inslag i företagens marknadskommunikation. Trots denna tillväxt har event marketing under en längre tid sammankopplats med brist på utvärderingsmetoder. En avsaknad av utvärderingsmetoder leder till svårigheter att avgöra vilka effekter en event marketing-satsning resulterar i, hur genomförandet kan förbättras samt huruvida event marketing är en lämplig form av mar...

    Full Text Available Målet med artikkelen er å synliggjøre hvordan bachelorstudenter i ergoterapi kan utvikle profesjonell handlingskompetanse gjennom aktivitetsbasert pedagogikk. På bakgrunn av dette gjennomførte vi kvalitative fokusgruppeintervju med 12 ergoterapeutstudenter som hadde deltatt i undervisningsopplegget “Aktivitetsgrupper-lede og delta”. Datamaterialet ble analysert etter retningslinjer for fenomenologisk basert meningskondensering. Studentene diskuterte sine erfaringer og det kom tydelig fram at undervisningsopplegget ga dem muligheter til å bruke sitt engasjement og sin kreativitet i valg av aktiviteter for sin simulerte aktivitetsgruppe. Videre fikk de muligheter til å oppdage sider ved anvendelse av aktiviteter for ulike pasienter, som de ikke kunne forstå uten integrering av teori i praktisk ferdighetstrening. Ved planlegging, gjennomføring og refleksjon over å lede og delta i aktivitetsgrupper, oppøvet de evnen til handlingsrefleksjon. Aktivitetsbasert pedagogikk kan bidra til utvikling av profesjonell handlingskompetanse og det er behov for både teoretiske og praktiske læringsformer. Funnene ble diskutert i lys av pedagogisk handlingsteori.

    Audio Video coding Standard (AVS) is established by the AVS Working Group of China. The main goal of AVS part 7 is to provide high compression performance with relatively low complexity for mobility applications. There are 3 main low-complexity tools: deblocking filter, context-based adaptive 2D-VLC and direct intra prediction. These tools are presented and analyzed respectively. Finally, we compare the performance and the decoding speed of AVS part 7 and H.264 baseline profile. The analysis and results indicate that AVS part 7 achieves similar performance with lower cost.

    2006-01-01

    Adaptive frame/field coding techniques have been adopted in many international video standards for interlaced sequence coding. When the frame/field adaptation is applied on the picture level, the coding efficiency is improved greatly,compared with the pure frame coding or the pure field coding. The picture-level adaptive frame/field coding (PAFF) selects frame coding or field coding once for one picture. If this frame/field adaptation is extended to Macro Block (MB) level, the coding efficiency will be further increased. In this paper, a novel MB-level adaptive frame/field (MBAFF) coding scheme is proposed. In the proposed MBAFF scheme, the top field of the current picture is used as a reference. The experiments are implemented on the platforms of Audio Video coding Standard (AVS) base profile and H.264/AVC, respectively. On the AVS platform, 0.35dB gain can be achieved averagely, compared with AVS1.0 anchor. On the H.264/AVC platform, 0.16dB gain can be achieved averagely, compared with MBAFF scheme of H.264/AVC. Additionally, an extensive subjective quality enhancement can be achieved by the proposed scheme.

Det handler om abort, medisinsk teknologi og valg av barn. Det kan synes som om vi står overfor nye muligheter for fravalg og tilvalg som ikke bare setter en ny debatt, men som samtidig krever en tilbakevending og nyåpning av tidligere gjennomdiskuterte spørsmål og tema. Debattene rundt «valg av barn» berører dype, eksistensielle dimensjoner ved menneskelivet.

    Following the success of the audio video standard (AVS) for 2D video coding, in 2008, the China AVS workgroup started developing 3D video (3DV) coding techniques. In this paper, we discuss the background, technical features, and applications of AVS 3DV coding technology. We introduce two core techniques used in AVS 3DV coding: inter-view prediction and enhanced stereo packing coding. We elaborate on these techniques, which are used in the AVS real-time 3DV encoder. An application of the AVS 3DV coding system is presented to show the great practical value of this system. Simulation results show that the advanced techniques used in AVS 3DV coding provide remarkable coding gain compared with techniques used in a simulcast scheme.

  12. Functional mathematical model of dual pathway AV nodal conduction.

    Science.gov (United States)

    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.

    Full Text Available En gjennomgang av spontanrapportene fra den norske bivirkningsdatabasen viser en betydelig geografisk variasjon når det gjelder innrapportering av bivirkninger. I Norge blir disse meldingene evaluert ved RELIS (Regionale legemiddelinformasjonssentre av tverrfaglige team bestående av leger og farmasøyter. Bivirkningsarbeidet ved RELIS gjøres på oppdrag fra Statens legemiddelverk, som har det overordnede ansvar for legemiddelovervåkningen i Norge. Vurderingene baseres på kjent risikoprofil for mistenkte legemidler, indikasjon, dosering, tidsmessig sammenheng mellom reaksjon og medikamentinntak, effekt av seponering og eventuelle andre risikofaktorer. 3345 legemiddel/bivirkningskombinasjoner ble vurdert på bakgrunn av 1408 rapporter i 2006. De fleste mistenkte bivirkningene ble klassifisert som mulige, ettersom andre faktorer også kunne ha spilt en rolle. Få bivirkninger ble klassifisert som sikre. Informasjon om bivirkninger i litteratur og databaser er i flere tilfeller preget av manglende homogenitet, tilfeldige sammentreff i tid, manglende data og lite vurdering av sammenhengen mellom reaksjonen og medisinbruken. Kliniske studier har begrenset mulighet til å påvise annet enn de vanligste bivirkningene. Det kan ta år etter markedsføring å fastslå sammenhengen med mer sjeldne bivirkninger. Frekvenstabeller for bivirkninger er anslag basert på et begrenset antall pasienter, spesielt for nye legemidler. Evaluering av bivirkningsrapporter fra helsepersonell kan avdekke mangel på lett tilgjengelig informasjon og bidra til ny kunnskap om et legemiddels bivirkningsprofil

  15. Russisk oljetransport gjennom Barentshavet : En tilfellestudie av den norske responsen

    OpenAIRE

    Aasen, Kari

    2010-01-01

    Oppgaven er en tilfellestudie av den norske responsen på økningen av russisk oljetransport gjennom Barentshavet. Oljetransporten fra Nordvest-Russland tok seg plutselig dramatisk opp i 2002, noe som kom svært overraskende på norske myndigheter. Hensikten med oppgaven har derfor vært å kartlegge den norske responsen, for å finne ut hva som har preget den. På bakgrunn av kjennetegnene ved responsen har jeg deretter forsøkt å sannsynliggjøre hvilke oppfatninger av Russland som vært dominerende. ...

  16. Konsum av risiko-matvarer - Beskrivelse av en undersøkelse som skal kartlegge konsum av matvarer med betydning for inntaket av miljøgifter

    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

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

    2014-09-01

    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.

    2016-01-01

    The second generation Audio Video Coding Standard (AVS2) is the most recent video coding standard. By introducing several new coding techniques, AVS2 can provide more efficient compression for scene videos such as surveillance videos, conference videos, etc. Due to the limited scenes, scene videos have great redundancy especially in background region. The new scene video coding techniques applied in AVS2 mainly focus on reducing redundancy in order to achieve higher compression. This paper introduces several important AVS2 scene video coding techniques. Experimental results show that with scene video coding tools, AVS2 can save nearly 40%BD⁃rate (Bjøntegaard⁃Delta bit⁃rate) on scene videos.

    2013-11-01

    Full Text Available Medisinsk forskning har ført til store framskritt de siste tiårene. Det er investert mye mer ressurser på basalforskning og klinisk forskning enn på å utvikle og evaluere metoder for å sikre at pasientene får nytte av forskningen. 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.

  4. Cofactor requirement of HpyAV restriction endonuclease.

    Directory of Open Access Journals (Sweden)

    Siu-Hong Chan

    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.

    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.

  17. AV-95 Sun Devil: High-Speed Military Rotorcraft

    Science.gov (United States)

    1996-01-01

    The AV-95 Sun Devil must combine helicopter capabilities, such as vertical takeoff and landings (VTOL) and rotor-powered flight, along with long-duration cruise and high-speed dash capabilities unobtainable by conventional helicopters. To be able to perform both tasks, and perform them well, the AV-95 Sun Devil design incorporates several unconventional devices; the AV-95 uses two convertible turbofan engines, able to provide both shaft power for the main rotor and tall fan as well as jet thrust either separately or simultaneously. Other devices used for the AV-95 include a variable diameter main rotor and a blown flap. In helicopter mode, the AV-95 Sun Devil performs like a winged helicopter. The addition of wings to an attack helicopter results in two significant advantages. First, the addition of wings makes a helicopter more maneuverable than a wingless, but otherwise similar helicopter. Second, since the wings produce lift, rotor stall and compressibility effects can be significantly delayed at high tip velocities. In fixed-wing mode, the main rotor is completely off-loaded but slightly powered, and the rotor diameter has been minimized. The AV-95 Sun Devil has many advantages over other VTOL aircraft. The conversion process is simple and fast; conversion does not make the AV-95 vulnerable to enemy attack during conversion such as a tilt-wing or a tilt-rotor. Stop-rotor aircraft and a stowed rotor aircraft require heavy breaking of the rotor for conversion; this adds time for conversion and weight to the aircraft. Because the AV-95 never stops the rotor in flight, much weight is spared, and conversion is much simpler and faster.

    Full Text Available Hva menes med at noe er ”godt dokumentert”? I hvilken grad kan vi stole på forskningsresultater? Den mest brukte metoden for å vurdere kvalitet på dokumentasjon og styrke på anbefalinger er GRADE (Grading of Recommendations Assessment, Development and Evaluation. GRADE brukes i systematiske oversikter og i retningslinjer der man vurderer effekten av og gir anbefalinger om ulike behandlingsalternativer. I GRADE gjøres et klart skille mellom kvaliteten på dokumentasjonen og styrken på anbefalingene. For å vurdere kvaliteten på dokumentasjonen tar GRADE utgangspunkt i en godt utført systematisk oversikt som omfatter den aktuelle problemstillingen. Både randomiserte forsøk og observasjonsstuder kan inngå. GRADE benytter fem kriterier som vurderes for eventuell nedgradering av kvaliteten på dokumentasjonen: studiekvalitet, konsistens mellom studiene, direkthet, presisjon og rapporteringsskjevheter. I tillegg kan observasjonsstudier vurderes for oppgradering ved følgende tre kriterier: sterke assosiasjoner, dose-responseffekter og forvekslingsfaktorer. Alle vurderingene noteres og presenteres sammen med resultatene i oppsummeringstabeller.Vist GE, Sæterdal I, Vandvik PO, Flottorp SA. Grading the quality of the evidence.

    Ometto, R; Thiene, G; Corrado, D; Vincenzi, M; Rossi, L

    1992-11-01

    The basic anatomical substrate of enhanced A-V nodal conduction, manifesting or not as Lown-Ganong-Levine syndrome, is still a controversial issue. We describe the case of a 34-year-old man who presented episodes of ventricular fibrillation. Electrophysiological studies showed that the AH interval was 55 ms, and increased by only 20 ms at paced cycle lengths of 300 ms; atrial pacing induced atrial fibrillation, with a shortest RR interval of 240 ms. Despite verapamil therapy, this patient died suddenly at home. Histological study disclosed a severe A-V node hypoplasia that was evidently congenital in nature; the rest of the conduction system was normal, and no accessory A-V pathways were present. We suggest that enhanced A-V nodal conduction in this patient was due to the developmental defect in the A-V node; this abnormality caused a loss of specific impulse-delaying function, and thus allowed rapid, unfiltered atrial impulses to reach the lower A-V junction and ventricles.

    The Av-13 (Tuccia) and Av-14 (Urbinia) quadrangles are located in the south-west region of Vesta. They are characterized by a large topographic variability, from the highest (Vestalia terra highlands) to the lowest (Rheasilvia basin). Many geological units in these quadrangles are not associated with mineralogical variability, as shown by the color-composite maps. Maps of mafic absorption band-center position reveal that the principal lithology is eucrite-rich howardite, but diogenite-rich howardite areas are also present, corresponding to particular features such as Antonia and Justina craters, which are characterized by strong mafic absorptions. These quadrangles, especially Urbinia, contain many bright ejecta, such as those of Tuccia crater, which are the highest reflectance materials on Vesta (Zambon et al., 2014). Dark areas are present and correspond to regions with deeper OH-signature. The two quadrangles contain many vertical ridge crests associated with the Rheasilvia impact. These ridges do not show mineralogical differences with respect to their surroundings, but have a distinctive appearance in color-ratio composite images.

    As to the complexity process of choosing best probable encoding mode in AVS intra prediction,we proposed a fast intra predic-tion encoding algorithm.With the analysis of AVS intra prediction encoding theory and its implementation in reference software GDM2.1,we derived the threshold of zero coefficient block determination.The fast algorithm determines whether or not the current block is a zero coeffi-cient block according to its threshold discriminant condition.For zero coefficient block,it encodes cbp element directly and terminates intra prediction encoding in advance,which avoids the consequent complex process.As for the non-zero coefficient blocks,the fast selection algo-rithm associating the time domain SAD and the frequency domain SATD is used,which excludes 40% to 80% impossible prediction modes, and the rate distortion function is applied to the remained prediction modes to select the best prediction mode.It was verified through experi-ment that when PSNR (peak signal-to-noise ratio)decreased within 0.25db and bits rate increased within 2%,the time of AVS encoding de-creased over 40%,and the encoding efficiency was largely improved as well.%针对 AVS(Audio Video code Standard)帧内预测中选择最优编码模式流程复杂的问题,提出一种快速帧内预测编码的算法。通过分析 AVS 帧内预测编码的原理及其在参考软件 GDM2.1中的代码实现,推导出判定零系数块的阈值。该快速算法根据零系数块的判定阈值条件判定当前块,对于零系数块,直接编码 cbp 元素,提前中止帧内预测编码,避免了后续的复杂流程;对于非零系数块,采用时域 SAD(Sum of Absolute Difference)与频域 SATD(Sum of Absolute Transformed Difference)相联合的快速选择算法,排除了40%~80%的不可能预测模式,对余下的模式采用率失真代价函数的方法选取最佳预测模式。经实验验证,在 PSNR(Peak Sig-nal to Noise Ratio)降低0

  7. Utviklingen av Noark-standarden 1984 – 2008

    2014-11-01

    Full Text Available Artikkelen behandler utviklingen av Noark – standarden for elektronisk arkivdanning i norsk offentlig forvaltning – fra versjon 1 (1984 til versjon 5 (2008. Den beskriver omstendighetene som medførte at standarden ble til i 1984, og søker å forklare hvorfor og hvordan det lyktes å utbre standarden slik at Noark-systemer ble enerådende i offentlig forvaltning i løpet av 1990-årene. Riksarkivarens strategier i Noark-utviklingen behandles, – de som fra først av fikk Riksarkivaren til å engasjere seg i standardiseringsarbeidet, de som deretter fikk Riksarkivaren til å overta forvalteransvaret for Noark, og de som senere er endret eller justert som resultat av erfaringer med Noark-baserte systemer og av nyåpnede teknologiske muligheter. Særlig vekt legges på å belyse Riksarkivarens motiver for å overta ansvaret for Noark-standarden fra 1990. Noark plasseres også i det internasjonale bildet, og sammenholdes med andre standarder som ISO 15489 og EU-standarden MoReq. Da Noark-utviklingen startet i 1984, pågikk tilsvarende utviklingsprosjekter både i Danmark og i Sverige. Artikkelen søker forklaringer på at en journal- og sakarkivstandard bare ble en realitet i Norge.

  9. The role of AV and VV optimization for CRT

    Directory of Open Access Journals (Sweden)

    William W. Brabham, M.D.

    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.

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

    2014-01-01

    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.

  13. Lesing av delvis motstridende tekster i syvende klasse

    Directory of Open Access Journals (Sweden)

    Wenke Mork Rogne

    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.

På bakgrunn av erfaringer med to forskerskoler innenfor utdanningsvitenskap, vil vi i denne artikkelen belyse to problemstillinger: Hvordan kan man organisere læringsforløpet til ph.d.-kandidatene slik at det støtter deres progresjon? Og hva må forskerutdanningen inneholde for at ph.d.-kandidatene skal utvikle tilstrekkelig ekspertise innenfor et avgrenset kunnskapsområde?For å skape progresjon, bør utdanningsprogrammet bidra til å gi struktur og angi faglig retning. Videre må utdanningselementene være relevante for avhandlingsarbeidet. I tillegg kan progresjon fremmes gjennom seminarer, der utviklingen av tekster og artikler følges opp. Argumentet om at forskerskoler bør bygge på gode forskningsmiljøer har stått sentralt i utredningen av ulike modeller for forskerutdanning i Norge. Ett aspekt som har fått økende oppmerksomhet er betydningen av å oppnå en tilstrekkelig grad av spesialisering. Uten utvikling av en slik ekspertise, vil ph.d.-kandidatene ikke kunne publisere internasjonalt og delta i forskningsfellesskap.Ved Det utdanningsvitenskapelige fakultet har man de siste 10 årene utviklet flere typer forskerskoler. I denne artikkelen tar vi utgangspunkt i den UiO-finansierte, tematisk avgrensede forskerskolen «Læring, kommunikasjon og IKT» (2004–2008 og den NFR-finansierte nasjonale forskerskolen i utdanningsvitenskap, NATED (2008–2016, hvor ph.d.-kandidatene deltar i faglige aktiviteter organisert i fire spor.Metodene som brukes for å besvare problemstillingene omfatter intervjuer, spørreskjema og refleksjoner vedrørende de to ulike forskerskolene.Resultatene viser at man kan oppnå nødvendig spesialisering, høy kvalitet, høy tilfredshet og høy relevans ved bruk av forskerskoler som virkemiddel i forskerutdanningen. Begge forskerskolene har tilrettelagt for internasjonal

  13. 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.

    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.

    Minn, Young Guy; Choi, Hyung Ki [Yonsei University College of Medicine, Seoul (Korea, Republic of)

    1994-09-01

    Audio visual simulation penogram(AVS-penogram) is used as a screening method for evaluation of erectile dysfunction. In this study, 3000 patients were evaluated from Dec. 1986 to Dec. 1992 and finally diagnosed by comprehensive diagnostic methods. The patients were classified according to AVS-penogram curves into 4 types and correlated with the patient`s final diagnosis. For 800 patients who were evaluated with combined AVS-penogram and NPT monitoring, compatibility ratios between psychogenic and organic group were compared. After correlating each of the curve type with the patients and comparing erotic and nocturnal erection, following results were obtained. 1. The mean age of the patients was 41.25 years. 2. The overall rate of final diagnosis were 57.5%, 14.3%, 8.9% in psychogenic, arteriogenic and veogenic impotence. 3. Type I group was proved as psychogenic impotence in 87% of the patients. 4. Type IIA group was proved as organic impotence in 79% of the patients and most of them had neurogenic and arteriogenic impotence. 5. Type IIB group was proved as psychogenic impotence in 51%, organic impotence in 49% of the patients. Among the organic impotence group, most of them had arteriogenic, venogenic and neurogenic impotence. The difference of both group was statically insignificant. 6. Type IIC group was proved as psychogenic impotence in 39%, organic impotence in 61% of the patients. Further studies are needed for sub-classification of both groups. 7. The compatibility ratio of the AVS-penogram and NPTM was 85.9% in psychogenic group with normal finding in both tests and 44.7% in organic group with abnormal finding in both tests. In conclusion, AVS-penogram is a primary diagnostic method in screening impotent patients and type I is regarded as psychogenic impotence. In Type IIB and IIC, sub-classification of curve type is needed for differential diagnosis between psychogenic and organic impotence. (Abstract Truncated)

    Apolipoprotein AV (apoAV) modulates plasma triglyceride levels, which is an independent risk factor for cardiovascular disease. ApoAV is also involved in atherosclerosis lesion formation. In order to systematically evaluate the apolipoprotein-related gene profile in tree shrew, a model for its insusceptibility to atherosclerosis, we performed apoAV cloning and characterization. The full-length cDNA of apoAV was identified using SMART-RACE. ApoAV cDNA sequence revealed two transcripts, 1,948 and 1,397 base pairs, due to alternative polyadenylation. These two transcripts share the same open reading frame (ORF), which encodes a 369-amino acid protein with high identity to human apoAV (75 %), including a 23-amino acid N-terminal signal peptide. ApoAV is expressed exclusively in the liver. Mature apoAV was expressed in E. coli BL21(DE3) and purified by Ni-chelated resin. Lipoprotein lipase activity was significantly stimulated by this recombinant protein. The full-length ORF of apoAV was cloned into pDsRed-monomer-N1 vector with a red fluorescent protein tag and was primarily localized in cytoplasm of hepG2 cells. The successful cloning, expression and localization of apoAV in tree shrew has laid down the foundation for further investigation on its structure and functions.

  2. Viktigheten av fysisk aktivitet og trening blant eldre

    Full Text Available Regelmessig fysisk aktivitet er viktig for eldres helse. Sammenhengen mellom en fysisk aktiv livsstil og helsegevinster som forebygging av sykdom, opprettholdelse av uavhengighet og økt livskvalitet er godt dokumentert (ACSM's Position Stand 1998; Spirduso & Cronin, 2001; Taylor et al., 2004. Hensikten med denne oversiktsartikkelen er derfor å redegjøre for viktigheten av regelmessig fysisk aktivitet og trening i aldringsprosessen, samt utdype sammenhengen mellom en fysisk aktiv livsstil og fysisk funksjon blant eldre. Basert på en nasjonal multisenterstudie (Anderssen et al., 2009, tilfredsstilte 20% voksne og eldre (20-85 år de nasjonale anbefalinger om 30 minutter med daglig fysisk aktivitet. Kun 12% i den eldste aldersgruppen (80-85 år tilfredsstilte anbefalingene. Totalt fysisk aktivitetsnivå, målt ved hjelp av akselerometer, ble redusert med økende alder, hvor de eldste (80-85 år hadde 50% lavere aktivitetsnivå sammenlignet med de yngste (65-69 år (Lohne-Seiler et al., 2012. Fra 25-års alder reduseres utholdenhet og muskelstyrke med 10% per 10 år dersom individet er inaktiv (Heath et al., 1981; Wilmore, 1991. Systematisk utholdenhets- og styrketrening ser derimot ut til å redusere tapet med inntil halvparten, det vil si en reduksjon tilsvarende 5% per 10 år hos fysisk aktive individer (Heath et al., 1981. Eldre individer ser ut til å ha de samme treningsinduserte effekter som yngre, det vil si at man får effekt av økt aktivitet uansett alder, og da også lik prosentvis fremgang (Hagberg et al., 1989. Studier har vist at det er mulig å øke maksimalt oksygenopptak og maksimal muskelstyrke med inntil 10-20% i løpet av en 12 ukers intervensjon (Hagberg et al., 1989; Reeves et al., 2003; Lohne-Seiler et al, in press. Da muskelstyrke ser ut til å ha en sterk sammenheng med individets funksjonsevne/mobilitet, er det viktig å kunne tilrettelegge for systematisk styrketrening for eldre for på den måten å oppnå

    Full Text Available Læreres kunnskap har betydning for elevenes læring, og som et ledd i prosessen for styrking av kvaliteten i norsk skole har politikere i senere tid ytret ønske om å kartlegge læreres kunnskap. Kartlegging av læreres kunnskap er imidlertid ikke enkelt, og i denne artikkelen undersøker vi hvordan de samme lærernes undervisningskunnskap i matematikk kan se ut til å være forskjellig når den måles ved hjelp av oppgaver med ulikt format. Deltakerne i studien var 30 praktiserende lærere, og instrumentet besto av 28 flervalgsoppgaver med tilhørende åpne oppgaver. Sammenhengen mellom lærernes kunnskap slik den måles ved hjelp av flervalgsoppgavene og de åpne oppgavene er ikke alltid klar. Det er derfor nødvendig å tilnærme seg måling av læreres undervisnings-kunnskap i matematikk med stor varsomhet. Nærmere undersøkelser er nødvendig for å finne ut hva slags type kunnskap som kan måles med ulike typer oppgaver og hva slags måleinstrumenter som kan brukes til hvilke formål.Nøkkelord: Undervisningskunnskap i matematikk, kartlegging, måleinstrument-er, flervalgsoppgaver AbstractTeachers’ knowledge influence students’ learning, and as part of their attempts to increase the quality of Norwegian schools, politicians have announced their intentions to measure the knowledge of teachers. Measuring teacher knowledge is not straightforward, however, and this article investigates how a group of mathematics teachers’ knowledge might appear different when measured by items of different formats. The participants in this study were 30 in-service teachers, and the instrument consisted of 28 multiple-choice items with associated open-response items. The connection between the teachers’ know-ledge as measured by multiple-choice items and open-response items is not always straightforward. As an implication, it is necessary to approach measure-ment of teachers’ mathematical knowledge for teaching with great care. Further studies are

    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.

  4. Toward robust AV conferencing on next-generation networks

    In order to enable a truly pervasive computing environment, next generation networks (including B3G and 4G) will merge the broadband wireless and wireline networking infrastructure. However, due to the tremendous complexity in administration and the unreliability of the wireless channel, provision of hard-guarantees for services on such networks will not happen in the foreseeable future. This consequently makes it particularly challenging to offer viable AV conferencing services due to their stringent synchronization, delay and data fidelity requirements. We propose in this paper a robust application-level solution for wireless mobile AV conferencing on B3G/4G networks. Expecting no special treatment from the network, we apply a novel adaptive delay and synchronization control mechanism to maintain the synchronization and reduce the latency as much as possible. We also employ a robust video coding technique that has better error-resilience capability. We investigate the performance of the proposed solution through simulations using a three-state hidden Markov chain as the generic end-to-end transport channel model. The results show that our scheme yields tight synchronization performance, relatively low end-to-end latency and satisfactory presentation quality. The scheme successfully provides a fairly robust AV conferencing service.

    Full Text Available Yrkesutbildning skiljer sig från andra former av gymnasieutbildning genom att den innehåller praktisk kunskap som kan vara svårfångad, ofta benämnd som tyst kunskap. Tyst kunskap utgör en förutsättning för att yrkeselever ska kunna tillägna sig ett yrkes kultur, praxis och kunskapstradition. Med utgångspunkt i yrkeslärares berättelser beskrivs i artikeln med stöd av tre definierade kompetensområden, 1 yrkesfältet, 2 handlag i yrket samt 3 interaktion och social kompetens, hur yrkeslärare arbetar för att möjliggöra att ett yrkes tysta kunskaper kan läras i en skolmiljö. Resultatet visar betydelsen av att yrkeslärares tysta kunskaper blottläggs för eleverna genom att de i sin undervisning, berättar, visar och ställer frågor. Det är i dessa möten som den tysta kunskapens betydelse i yrkesutövning kan bli synlig för eleverna.

  6. Bruk av ordlæringsstrategier blant norske tyskelever

    Full Text Available Interessen for forskning på læringsstrategier er økende i Norge. Det finnes likevel ennå ingen publiserte empiriske studier som fokuserer på læringsstrategier i andre fremmedspråk. Hensikten med den foreliggende artikkelen er å gi et første innblikk i 54 norske tyskelevers bruk av ordlæringsstrategier. Studien er gjennomført som en skriftlig spørreundersøkelse hvor elevene beskrev hvordan de hadde arbeidet for å lære en liste med tysk-norske ordpar. Samlet sett ser vi at elevene behersker ordlæringsstrategier av ulik art, men at noen få strategier er hyppig forekomne hos de fleste elevene. Det viser seg at elevene i hovedsak bruker ordlæringsstrategier som inneholder element av repetisjon, altså strategier som krever lite kognitiv bearbeiding. Dernest blir metakognitive strategier som organiserer og planlegger læringen mest brukt. Artikkelens siste del sammenligner funn fra undersøkelsen med internasjonale studier og skisserer videre forskningsbehov innen feltet.

    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

En siste svakbølge fant sted vinteren 1920. De første sporadiske tilfellene av spanskesyken i Norge oppsto i militærleirei begynnelsen av april 1918. Over tre måneder senere kom de første spredte tilfellene av det som skullevise seg å være starten på en ny stor influensapandemi. De første av disse oppsto i Kristiania, mest sannsynligetter smitteimport fra Skottland over Nordsjøen. Sommeren 1918 spredte spanskesyken seg raskt frasør til nord, fra kysten til innlandet innover fjordene, og fra de største byene og industrisentra via mindrebyer og andre tettsteder til landsbygda langs de viktigste ferdselsveiene. Da spanskesyken blusset opp igjenhøsten 1918 spredte den seg langsommere og trolig fra nord til sør, fortsatt fra kysten innover fjordene,men spredning fra byene langs kommunikasjonsveiene var mindre fremtredende. Vinteren 1918/19opptrådte influensaen spredt og sporadisk, tilsynelatende uten bestemt spredningsmønster og rekkefølge.Jernbanen, hurtigruten og automobilrutene spilte trolig en viktig rolle i spredningsprosessen, spesielt andrehalvår 1918.

  14. STUDY ON EFFICIENT COMPUTATION AND PERFORMANCE OF AV-BASED REDUCED-RANK FILTERING

    Institute of Scientific and Technical Information of China (English)

    Xu Bin; Yang Chenyang; Mao Shiyi

    2005-01-01

    In this paper, the complexity and performance of the Auxiliary Vector (AV) based reduced-rank filtering are addressed. The AV filters presented in the previous papers have the general form of the sum of the signature vector of the desired signal and a set of weighted AVs,which can be classified as three categories according to the orthogonality of their AVs and the optimality of the weight coefficients of the AVs. The AV filter with orthogonal AVs and optimal weight coefficients has the best performance, but requires considerable computational complexity and suffers from the numerical unstable operation. In order to reduce its computational load while keeping the superior performance, several low complexity algorithms are proposed to efficiently calculate the AVs and their weight coefficients. The diagonal loading technique is also introduced to solve the numerical unstability problem without complexity increase. The performance of the three types of AV filters is also compared through their application to Direct Sequence Code Division Multiple Access (DS-CDM A) systems for interference suppression.

    We report the case of a 46-year old patient in whom an electrophysiology study (EP) was performed due to paroxysmal supraventricular tachycardia documented in 12-lead ECG. During the EP study, supraventricular tachycardia was induced easily and it corresponded to orthodromic AV reentry tachycardia (AVRT) using a concealed left free wall accessory pathway. However, during the study AVRT spontaneously and repeatedly converted to the typical slow-fast AV node reentry tachycardia (AVNRT). Both accessory and AV nodal slow pathways were ablated, due to the finding that both AVRT and AVNRT were independently inducible during the EP study.

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

    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.

    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

    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.

  9. Posthumanisme /nymaterialisme og nomadisme - affektive brytninger av barnehagens observasjonspraksiser

    Full Text Available This article challenges observation as a method in early childhood, justified as a mapping tool for creating knowledge about children. Observation as data material is about writing down already known categorisation about children and their development. Categories and categorisation make a foundation for correspondence and coherence   - connections that might create generalising knowledge about children in early years. The article is about a research project conducted in a child-centre over a two-year period. We had an on-going conversation with the personnel around theories about ‘child development’. In the article we experiment with observation based on posthuman/newmaterial theories. Our specific interests are to explore the complexities around observation by asking; why observations, what do we expect through observation, and what might observation as datamaterial be/become? We are inspired by the Norwegian film “Kitchen Stories” (Salmer fra Kjøkkenet, Hamer, 2003 both as affect/provocation and desire (Koro-Ljungberg & MacLure, 2013. We search for affective bending and messiness (Lather, 2007; Law, 2004 to disturb and challenge observation as dominating paradigm in the field of early years, to break some patterns around the positioning of data material. Artikkelen utfordrer observasjon i barnehagen ut fra at metoden brukes som verktøy for å kartlegge og danne grunnlaget for utvikling av kunnskap om barn.  Observasjon som datamateriale innebærer iakttagelser og nedtegnelser av allerede gitte kategoriseringer om barn og barns utvikling.  Kategorier og kategorisering legger grunnlag for mønster som har i seg ideer om korrespondanse og koherens – sammenhenger som kan bidra til generaliserende kunnskap om barna i barnehagen. Omrisset av artikkelen dreies rundt et forskningsarbeid gjort i en barnehage over en toårs-periode, der vi sammen med de ansatte diskuterer teorier om barn og barns ’utvikling’. Vi bruker posthumane

  3. Endogenous RGS proteins modulate SA and AV nodal functions in isolated heart: implications for sick sinus syndrome and AV block.

    G protein-coupled receptors play a pivotal role in regulating cardiac automaticity. Their function is controlled by regulator of G protein signaling (RGS) proteins acting as GTPase-activating proteins for Galpha subunits to suppress Galpha(i) and Galpha(q) signaling. Using knock-in mice in which Galpha(i2)-RGS binding and negative regulation are disrupted by a genomic Galpha(i2)G184S (GS) point mutation, we recently (Fu Y, Huang X, Zhong H, Mortensen RM, D'Alecy LG, Neubig RR. Circ Res 98: 659-666, 2006) showed that endogenous RGS proteins suppress muscarinic receptor-mediated bradycardia. To determine whether this was due to direct regulation of cardiac pacemakers or to alterations in the central nervous system or vascular responses, we examined isolated, perfused hearts. Isoproterenol-stimulated beating rates of heterozygote (+/GS) and homozygote (GS/GS) hearts were significantly more sensitive to inhibition by carbachol than were those of wild type (+/+). Even greater effects were seen in the absence of isoproterenol; the potency of muscarinic-mediated bradycardia was enhanced fivefold in GS/GS and twofold in +/GS hearts compared with +/+. A(1)-adenosine receptor-mediated bradycardia was unaffected. In addition to effects on the sinoatrial node, +/GS and GS/GS hearts show significantly increased carbachol-induced third-degree atrioventricular (AV) block. Atrial pacing studies demonstrated an increased PR interval and AV effective refractory period in GS/GS hearts compared with +/+. Thus loss of the inhibitory action of endogenous RGS proteins on Galpha(i2) potentiates muscarinic inhibition of cardiac automaticity and conduction. The severe carbachol-induced sinus bradycardia in Galpha(i2)G184S mice suggests a possible role for alterations of Galpha(i2) or RGS proteins in sick sinus syndrome and pathological AV block.

    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.

    Full Text Available SAMMENDRAGI første del av denne artikkelen gjennomgås en del utvalgte studier av skolebaserte tiltak mot røyking. Utviklingenhar gått gjennom tre faser der den siste generasjonen er de omfattende tiltakene som baserer seg på ensosial påvirkningsmodell. Godt planlagte tiltak som er basert på denne modellen har vist seg å føre til at færrebegynner å røyke. I artikkelens andre del presenteres et prosjekt som gjennomføres av Den NorskeKreftforening og som omfatter 4 441 elever fra 195 klasser ved 99 ungdomsskoler. Valg av undervisningstemaog pedagogiske tilnærminger er begrunnet i aktuelle sosialpsykologiske begreper og modeller ogerfaringer fra tidligere forskning. Intervensjonen bygger et stykke på vei på en sosial påvirkningsmodell.Skolene er delt i fire grupper. Gruppe A er kontrollgruppe. Elevene i gruppe B gjennomgår et undervisningsprogram,foreldrene involveres og lærerne gjennomgår kurser i hvordan de skal gjennomføre intervensjonen.I gruppe C gjør en det samme som i gruppe B, men lærerne kurses ikke. I gruppe D gjør en det samme som igruppe B, men foreldrene involveres ikke. Underveis gjennomføres det blant annet spørreskjemaundersøkelserblant elevene for å studere endringer i røykevaner, hvilke grupper av elever en lykkes best i å nå,hvordan elevene reagerer på tiltakene og hva som kan forklare eventuelle positive virkninger av intervensjonene.Foreløpige analyser av resultatene etter et halvt års oppfølging tyder på at det er færrest sombegynner å røyke i gruppe B, med andre ord at virkningene av tiltakene er best der lærerne kurses ogforeldrene involveres.Jøsendal O, Aarø LE, Bergh IH. School-based prevention of smoking among youths.Nor J Epidemiol ENGLISH SUMMARYThe first part of this article presents selected studies of school-based intervention programmes againstsmoking.

    The federal government advocates the practice of routinely providing an after-visit summary (AVS) to patients after each office-based visit as an element of stage 1 meaningful use. A significant potential benefit of the AVS is improved patient engagement achieved by enabling patients and family members to better understand and retain key health information. The methodology for this study was a mixed-methods pilot study to examine, through the perspectives of adult primary care patients, how relevant and actionable data can be better formatted in the AVS. Results of this study suggest that the goal of the AVS to serve as a communication tool to engage and support patients is frequently not being met. Further study is needed to understand, from the viewpoints of patients and providers, what barriers are keeping them from optimally providing and using the information on the AVS.

  1. Vurdering av andrespråksinnlærere - en utfordring i skolen

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Vurdering av andrespråkselevers språkkompetanse og språkutvikling er en sentral del av læreres arbeid, og forskning har vist at dette er en utfordring for skolene. Det er stor variasjon i vurderingsformer, og skolene mangler ofte vurderingskompetanse. På bakgrunn av dette utarbeidet Utdanningsdirektoratet i 2007 vurderingsverktøyet Kartleggingsmateriell. Språkkompetanse i grunnleggende norsk for språklige minoriteter. Materiellet er utarbeidet blant annet med referanse til Common European Framework of Reference for Languages (CEFR. I artikkelen redegjør vi for en undersøkelse der målet var å finne ut hvorvidt dette kartleggingsmateriellet er hensiktsmessig for å vurdere andrespråkselevers språkkompetanse. Hoveddataene er innhentet gjennom kasusstudier ved tre grunnskoler, der vi intervjuet skoleledelse og lærere samt observerte kartleggingssituasjoner og klasseromsundervisning. Kasusstudiene ble senere fulgt opp av to spørreundersøkelser, én til de samme skolene, og én til et større antall skoler for å få bredere innsikt i kartleggingspraksis og skolers oppfatninger av denne formen for vurdering. Undersøkelsen viser at flere av informantene mener verktøyet kan bidra til mer tilpasset og systematisk andrespråkopplæring og bedre vurdering av andrespråkselevenes språkkompetanse. Samtidig er det utfordringer knyttet til å bruke vurderingsverktøyet, dette skyldes blant annet mangelfull kompetanse i skolen når det gjelder andrespråkstilegnelse og vurdering av elevenes språkkompetanse. Det er ikke tidligere forsket på bruk av et slikt konkret kartleggingsverktøy i norsk grunnskole. Undersøkelsen kan gi et bidrag til økt kunnskap om vurdering av andrespråkskompetanse og tilpasset undervisning for andrespråksinnlærere.

    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.

    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).

    Objectives: This study was aimed at assessing the value of the adenosine test for noninvasive diagnosis of dual AV nodal physiology(DAVNP) in patients with AV nodal reentrant tachycardia (AVNRT). Methods: 53 patients with paroxysmal supraventricular tachycardia (PSVT) were given incremental doses of adenosine intravenously during sinus rhythm before electrophysiological study. The adenosine test was repeated on a subset of 18 patients with AVNRT after radiofrequency catheter ablation. Results: Sudden increments of PR interval of more than 60 msec between two consecutive beats were observed in 26(83.9%) of 31 patients with typical AVNRT and 2 (9.1%) of 22 patients with AVRT and AT (P<0.01). The maximal PR increment between 2 consecutive beats in the AVNRT group(105±45ms) was significantly greater than that in the AVRT and AT group (20±13ms) (P<0.01).In postablation adenosine test, DAVNP was eliminated in all 8 patients who underwent slow pathway abolition that EPS showed the slow pathway disappeared and 4 of 10 patients who underwent slow pathway modification that EPS showed the slow pathway persisted. Six of 10 patients who exhibited persistent duality showed a marked reduction in the number of beats conducted in the slow pathway after adenosine injection(P<0.01).Conclusions: Administration of adenosine during sinus rhythm may be a useful bedside test for diagnosis of DAVNP in high percentage of patients with typical AVNRT and additionally for evaluating the effects of radiofrequency ablation.

  7. 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

    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.

    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.

    Full Text Available Det pedagogiska ledarskapet inom högre utbildning fokuseras allt mer. Det understryks genom att flera lärosäten föreskriver såväl att pedagogiska ledare ska finnas på olika nivåer, som vilka övergripande uppgifter dessa ska ha. Denna artikel är ett resultat av en fallstudie av hur de tillägnade kunskaperna och färdigheterna från kursen Pedagogiskt ledarskap, en kurs för målgruppen studierektorer/pedagogiskt ansvariga eller motsvarande arrangerad av Universitetspedagogiskt centrum, har bidragit till deltagarnas professionalisering av det pedagogiska ledarskapet ett år efter kursens slut. Fallstudien genomfördes genom gruppintervjuer. Respondenterna uttryckte att de fått ett stärkt självförtroende i rollen som pedagogiska ledare samt att kursen bidrog till en professionalisering av rollen som pedagogiska ledare genom att stärka identiteten, att skapa en början till en handlingsetik bestående av delvis delade värderingar kring det pedagogiska ansvaret samt ge utbildning och träning i färdigheter som har sin grund i teoretisk kunskap.

    A new audio and video compression standard of China, known as advanced Audio Video coding Standard (AVS),is emerging. This standard provides a technical solution for many applications within the information industry such as digital broadcast, high-density laser-digital storage media, and so on. The basic part of AVS, AVS1-P2, targets standard definition (SD) and high definition (HD) format video compression, and aims to achieve similar coding efficiency as H.264/AVC but with lower computational complexity. In this paper, we first briefly describe the major coding tools in AVS1-P2, and then perform the coding efficiency comparison between AVS1-P2 Jizhun profile and H.264/AVC main profile. The experimental results show that the AVS1-P2 Jizhun profile has an average of 2.96% efficiency loss relative to H.264/AVC main profile in terms of bit-rate saving on HD progressive-scan sequences, and an average of 28.52% coding loss on interlace-scan sequences.Nevertheless, AVS1-P2 possesses a valuable feature of lower computational complexity.

  14. Developing a computational model of human hand kinetics using AVS

    1996-05-01

    As part of an ongoing effort to develop a finite element model of the human hand at the Institute for Scientific Computing Research (ISCR), this project extended existing computational tools for analyzing and visualizing hand kinetics. These tools employ a commercial, scientific visualization package called AVS. FORTRAN and C code, originally written by David Giurintano of the Gillis W. Long Hansen`s Disease Center, was ported to a different computing platform, debugged, and documented. Usability features were added and the code was made more modular and readable. When the code is used to visualize bone movement and tendon paths for the thumb, graphical output is consistent with expected results. However, numerical values for forces and moments at the thumb joints do not yet appear to be accurate enough to be included in ISCR`s finite element model. Future work includes debugging the parts of the code that calculate forces and moments and verifying the correctness of these values.

    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.

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.

Större studentgrupper och minskade resurser, parallellt med ett större utbud av distanskurser, gör att digitala lärplattformar blir än viktigare inom högre utbildning. Forskning visar dock att vi i första hand använder lärplattformar i administrativt syfte, trots möjligheter till en mer pedagogisk användning, exempelvis genom mer interaktion och ett större fokus på skrivandet.

    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.

    Recent studies have shown that positron emission tomography (PET) tracer AV-1451 exhibits high binding affinity for paired helical filament (PHF)-tau pathology in Alzheimer's brains. However, the ability of this ligand to bind to tau lesions in other tauopathies remains controversial. Our goal was to examine the correlation of in vivo and postmortem AV-1451 binding patterns in three autopsy-confirmed non-Alzheimer tauopathy cases. We quantified in vivo retention of [F-18]-AV-1451 and performed autoradiography, [H-3]-AV-1451 binding assays, and quantitative tau measurements in postmortem brain samples from two progressive supranuclear palsy (PSP) cases and a MAPT P301L mutation carrier. They all underwent [F-18]-AV-1451 PET imaging before death. The three subjects exhibited [F-18]-AV-1451 in vivo retention predominantly in basal ganglia and midbrain. Neuropathological examination confirmed the PSP diagnosis in the first two subjects; the MAPT P301L mutation carrier had an atypical tauopathy characterized by grain-like tau-containing neurites in gray and white matter with heaviest burden in basal ganglia. In all three cases, autoradiography failed to show detectable [F-18]-AV-1451 binding in multiple brain regions examined, with the exception of entorhinal cortex (reflecting incidental age-related neurofibrillary tangles) and neuromelanin-containing neurons in the substantia nigra (off-target binding). The lack of a consistent significant correlation between in vivo [F-18]-AV-1541 retention and postmortem in vitro binding and tau measures in these cases suggests that this ligand has low affinity for tau lesions primarily made of straight tau filaments. AV-1451 may have limited utility for in vivo selective and reliable detection of tau aggregates in these non-Alzheimer tauopathies.

    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.

    1980-07-15

    The functional dissociation (FD) of conduction within the AV-node is characterized by sudden prolongations and/or shortenings of the AH-time during stimulation. Examples for FD are presented during regular atrial stimulation and atrial extrastimulus technique. The appearance of FD is no proof for functional impairment of the AV-node. The blockade of the parasympathetic nervous system abolishes FD and leads to the well known continuous and regular adaptation of the AH-time with the various kinds of stimulation examined. It is recommended to replace the term "pathways" by the more comprehensive concept of functional dissociation with the AV-node.

    Full Text Available Denne artikkelen tar utgangspunkt i nyurbanismen, en amerikansk byplanleggingsbevegelse, og deres byutviklingsprosjekt Kentlands i Maryland, USA. Deres påstand er at en gjennom de rette designprinsippene vil få det ønskede samfunnet. Her argumenteres det for at den fysiske determinismen som ligger til grunn for den nyurbanistiske ideologien er for enkel. Mens nyurbanistene hevder at de skaper heterogene og lokaliserte fellesskap gjennom realiseringen av deres egne designprinsipper, hevdes det her med støtte i en sosialantropologisk studie av Kentlands at dannelsen av slike fellesskap er noe mer komplisert. Innbyggerne viste seg i praksis til og med å handle mot et slikt ideal. Sosial praksis, de nyurbanistiske designreglene, samt den felles interessen for å opprettholde eiendomsverdiene, førte til etableringen av en "eksklusiv enklave" snarere enn et inkluderende bomiljø.Nøkkelord: Nyurbanisme, byplanlegging, designregler, eksklusive enklaver

    2013-01-01

    We refine a classic relation between the hydrogen column density (NH) and optical extinction (Av) by employing 39 Galactic Supernova Remnants (SNRs) with X-rays, optical and/or infra-red data available. We find NH = (1.69+/-0.07)*10^21 Av cm^(-2) mag^(-1) . Applying this relation to three Galactic SNRs with good historical records allows us to further constrain either their progenitor's distances or magnitudes, which is independent access to their distances.

    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.

    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.

    [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.

    Full Text Available Insect-specific ascoviruses with a circular genome are distributed in the USA, France, Australia and Indonesia. Here, we report the first ascovirus isolation from Spodoptera exigua in Hunan, China. DNA-DNA hybridization to published ascoviruses demonstrated that the new China ascovirus isolate is a variant of Heliothis virescens ascovirus 3a (HvAV-3a, thus named HvAV-3h. We investigated the phylogenetic position, cell infection, vesicle production and viral DNA replication kinetics of HvAV-3h, as well as its host-ranges. The major capsid protein (MCP gene and the delta DNA polymerase (DNA po1 gene of HvAV-3h were sequenced and compared with the available ascovirus isolates for phylogenetic analysis. This shows a close relationship with HvAV-3g, originally isolated from Indonesia, HvAV-3e from Australia and HvAV-3c from United States. HvAV-3h infection induced vesicle production in the SeE1 cells derived from S. exigua and Sf9 cells derived from S. frugiperda, resulting in more vesicles generated in Sf9 than SeE1. Viral DNA replication kinetics of HvAV-3h also demonstrated a difference between the two cell lines tested. HvAV-3h could readily infect three important insect pests Helicoverpa armigera (Hübner, Spodoptera exigua (Hübner and Spodoptera litura (Fabricius from two genera in different subfamilies with high mortalities.

  13. 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%).

    Animal studies have shown that cerebral hypoperfusion may be associated with amyloid plaque accumulation. Amyloid plaque is known to be associated with dementia and [(18)F]AV-45 is a positron emission tomography (PET) ligand that binds to extracelluar plaques. We hypothesized that demented patients with cerebral hypoperfusion may have increased [(18)F]AV-45 uptake. Five demented patients with cerebral hypoperfusion due to unilateral carotid artery stenosis (CAS) were examined with [(18)F]AV-45 PET, and the results were compared with six elderly controls. The standard uptake value ratio (SUVR) of each region of interest (ROI) was created using whole cerebellum as the reference region. All subjects underwent magnetic resonance imaging (MRI) for obtaining structural information. Patients with dementia and unilateral CAS had a higher global [(18)F]AV-45 SUVR (1.34 ± 0.06) as compared with controls (1.10 ± 0.04, p=0.0043), especially over the frontal, temporal, precuneus, anterior cingulate and occipital regions. The statistical distribution maps revealed a significantly increased [(18)F]AV-45 SUVR in the medial frontal, caudate, thalamus, posterior cingulate, occipital and middle and superior temporal regions ipsilateral to the side of CAS (pAV-45 binding is increased in demented patients with CAS, and its distribution is lateralized to the CAS side, suggesting that amyloid-related dementia may occur under cerebral hypoperfusion.

    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.

Bakgrunnsopplysningene som sykepleierne reflekterte over, var kartlegging av trivsel og velvære hos pasientene innsamlet gjennom DCM-metoden, og meldt tilbake til personalet. Personalet opplevde at tilbakemeldingene førte til økt bevissthet i samhandling med pasientene. Ifølge deres utsagn medførte prosjektet flere konkrete endringer i måten de møtte pasientene på. Kartleggingen foretatt etter tre måneder viste større grad av trivsel og velvære i pasientgruppen. Dette peker i retning av at DCM kan være en nyttig metode for kvalitetsutvikling av demensomsorgen i sykehjem. Det er imidlertid behov for videre forskning med et strammere design og et større utvalg for å bekrefte funnene.

    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.

    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

    Full Text Available Universell utforming er et prinsipp hvor målsetningen er at «utforming av produkter og omgivelser [skal skje] på en slik måte at de kan brukes av alle mennesker, i så stor utstrekning som mulig, uten behov for tilpassing og en spesiell utforming.» (Aslaksen mfl, 1997, den første norske definisjonen I løpet av de siste 15 årene har dette prinsippet blitt fremmet i Norge som et utvetydig fremskritt. Det kan imidlertid være farlig å tro at en ren teknisk løsning kan bygge bro over politiske kontroverser (Imrie 2012, og i denne artikkelen vil vi vise hvordan viktige ideologiske premisser er skjult under paraplyen om universalitet. Vårt empiriske felt er norsk boligpolitikk fra etterkrigstiden og fram til i dag. Innenfor dette feltet ser vi at det har vært argumentert for ulike versjoner av «universell utforming» de siste 40 årene, selv om navnet «universell utforming» er av nyere dato. Vi vil vise hvordan prinsippet har endret seg fra å ha et sosialdemokratisk innhold – før det ble omdøpt til «universell utforming» – for å bli inkorporert i et nyliberalt boligpolitisk paradigme de siste 15 årene. De sosialdemokratiske forgjengerne til «universell utforming» ble til dels formulert som videreutviklinger av en boligpolitikk for sosial rettferdighet og økonomisk likhet. Med innføringen av begrepet «universell utforming» har denne brede sosiale rammen forsvunnet, men under dekke av universalitet og entydig framskrittsoptimisme har denne politiske endringen blitt underkommunisert.[i] [i] Prosjektet er finansiert av Husbanken.

    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.

    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.

    Progressive supranuclear palsy (PSP) is difficult to diagnose accurately. The recently developed tau PET tracers may improve the diagnostic work-up of PSP. Regional tau accumulation was studied using (18) F-AV-1451 PET in 11 patients with PSP and 11 age-matched healthy controls in the Swedish BioFinder study. (18) F-AV-1451 standard uptake volume ratios were significantly higher in the basal ganglia in PSP patients when compared with controls (globus pallidus 1.75 vs 1.50; putamen 1.51 vs 1.35). Retention in the basal ganglia was correlated with age in both groups (r = .43-.78, P AV-1451 retention was observed in the cerebral cortex or white matter of either PSP patients or controls, and autoradiography did not reveal any specific binding of AV-1451 to PSP tau aggregates. We found higher (18) F-AV-1451 retention in the basal ganglia of PSP patients when compared with healthy elderly controls, but also increases with age in both controls and patients. As a result of the overlap in retention between diagnostic groups and the age-dependent increase present also in controls, (18) F-AV-1451 PET might not reliably distinguish individual patients with PSP from controls. However, further studies are needed to evaluate whether (18) F-AV-1451 PET might be useful as a progression marker in clinical PSP trials. © 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.

    Full Text Available AV junction ablation has been proven effective to treat symptomatic atrial fibrillation refractory to antiarrhythmias or fail of pulmonary vein isolation. However, about 15% of conventional right-sided approach AV junction ablation failed to produce complete heart block. This study aimed to characterize His bundle potential at ablation site during conventional or left-sided approach of AV junction ablation. Twenty symptomatic AF patient (age of 60.5 ± 9.28 and 11 are females underwent conventional AV junction ablation. If 10 applications of radiofrequency energy are failed, then the ablation was performed by left-sided approach. Seventeen patients are successfully ablated by conventional approach. In 3 patients, conventional was failed but successfully ablated by left-sided approach. The His bundle amplitude at ablation site was significantly larger in left-sided than correspondence right-sided (16.0 ± 4.99 mm vs. 6.9 ± 4.02 mm respectively, p = 0.001, 95% CI -14.0 to -4.3. ROC analysis of His bundle potential amplitude recorded from right-sided revealed that cut off point of > 4.87 mm given the sensitivity of 81.3% and specificity of 53.8% for successful right-sided approach of AV junction ablation. In case of failed conventional approach, the left-sided approach is effective for AV junction ablation. An early switch to the left-sided approach may avoid multiple RF applications in patients with a low amplitude His-bundle potential (< 4.87 mm.

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.

    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.

    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.

    SL-AV (semi-Lagrangian, based on the absolute vorticity equation) is a global hydrostatic atmospheric model. Its latest version, SL-AV20, provides global operational medium-range weather forecast with 20 km resolution over Russia. The lower-resolution configurations of SL-AV20 are being tested for seasonal prediction and climate modeling. The article presents the model dynamical core. Its main features are a vorticity-divergence formulation at the unstaggered grid, high-order finite-difference approximations, semi-Lagrangian semi-implicit discretization and the reduced latitude-longitude grid with variable resolution in latitude. The accuracy of SL-AV20 numerical solutions using a reduced lat-lon grid and the variable resolution in latitude is tested with two idealized test cases. Accuracy and stability of SL-AV20 in the presence of the orography forcing are tested using the mountain-induced Rossby wave test case. The results of all three tests are in good agreement with other published model solutions. It is shown that the use of the reduced grid does not significantly affect the accuracy up to the 25 % reduction in the number of grid points with respect to the regular grid. Variable resolution in latitude allows us to improve the accuracy of a solution in the region of interest.

    There is a requirement for efficacious and safe medicines to treat diseases with high unmet need. The resurgence in av RGD integrin inhibitor drug discovery is poised to contribute to this requirement. However, drug discovery in the av integrin space is notoriously difficult due to the receptors being structurally very similar as well as the polar zwitterionic nature of the pharmacophore. This review aims to guide drug discovery research in this field through an av inhibitor toolbox, consisting of small molecules and antibodies. Small molecule av tool compounds with extended profiles in avb1, 3, 5, 6 and 8 cell adhesion assays, with key physicochemical properties, have been collated to assist in the selection of the right tool for the right experiment. This should also facilitate an understanding of partial selectivity profiles of compounds generated in different assays across research institutions. Prospects for further av integrin research and the critical importance of target validation are discussed, where increased knowledge of the selectivity for individual RGD v integrins is key. Insights into the design of small molecule RGD chemotypes for topical or oral administration are provided and clinical findings on advanced molecules are examined. © 2017 WILEY-VCH Verlag GmbH & Co.

    The goal of this study was to investigate the electrocardiographic and chronobio-logical features of paroxysmal atrioventricular (AV) block (PAVB) using data from ambulatory electrocardiography (AECG). The study population consisted of five men and six women aged from 47 to 82 years of age. Main presenting symptoms were pre-syncope in five patients (45.5%) and syncope in three patients (27.3%). Organic cardiovascular diseases were seen in eight patients (72.7%), and AV conduction disturbances were seen in six patients (54.5%), such as right bundle branch block, first to second degree AV block on standard 12-lead electrocardiography. Incidence of PAVB events were 1-329 (37.9 ± 98.0) episodes/patient/day, and the maximum pause during Holter recordings was 3.3-12.4 (6.39 ± 3.09) seconds. This maximum pause caused by intrinsic AV block was longer than that of vagally mediated AV block (8.4 ± 3.2 sec vs 4.7 ± 1.0 sec, p<0.05). In chronobiological analysis, episodes of PAVB exhibited a circadian rhythm characterized by a peak between 2:00 am and 4:00 am and a trough between 0:00 pm and 2:00 pm. AECG is a useful tool to detect the maximum pause occurring during sleep and provides critical data necessary to prevent the sudden cardiac death caused by PAVB.

    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.

    Full Text Available Artikkelen handler om hvordan journalføringskriteriene «gjenstand for saksbehandling» og «verdi som dokumentasjon» er ment å skulle forstås, basert på hvordan kriteriene er omtalt og definert i eksisterende teori og litteratur.Artikkelen viser at det ikke eksisterer en omforent forståelse av kriterienes innhold, det vil si at kriteriene er tillagt ulik betydning i ulike tekster. Det har tegnet seg et bilde av at de relativt få tekstene som faktisk inneholder beskrivelser av journalføringskriteriene og begrepene kriteriene er bygget opp av, i hovedsak nærmer seg kriteriene enten på en dialektisk-relasjonell eller på en semiotisk-relasjonell måte, hvilket gir to tilsynelatende ulike tolkningsresultater. Det foreligger med andre ord en viss tolkningsmotstrid, hvilket nødvendigvis innebærer at det fortsatt er vanskelig å svare entydig på spørsmålet om hvordan journalføringskriteriene er ment å skulle forstås, og samtidig gir grunn til kritikk av det etablerte systemet.

    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.

    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.

    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. PMID:27561012

    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.

    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.

    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.

  19. Betydningen av drektige reinsimlers ernæring for kalvers vekst, klimatiske toleranse og overlevelse

    Full Text Available Forsøkene (viste at tilleggsforing av underernærte simler i siste del av drektighetsperioden kun synes å ha effekt på fødselsvekten for kalvene forutsatt at simlene får høyverdig ernæring etter kalving. Den forskjellige ernæringsbakgrunn før kalving synes således ikke å innvirke på melkeproduksjon/kvalitet, da vektutviklingen for alle grupper av kalver i dette forsøket gikk parallelt i de tre første ukene etter kalving. Det ble heller ikke på noe punkt funnet signifikante forskjeller gruppene imellom når det gjelder kalvenes klimatiske toleranse. Det er dog bemerkelsesverdig at det var stor dødelighet blant de små kalvene etter unge små simler i GRUPPE L. Dette funn er interessant sett i sammenheng med resultatene fra Røros (se bidrag fra Dag Lenvik, side som viser at avkastningen fra en flokk kan økes markant om man konsentrerte slakteuttaket på små kalver og forhindrer bedekning av små, unge simler gjennom fjerning av eldre, store bukker. Med det forbehold at våre forsøk er utført på dyr i innhegning med et lavt aktivitetsnivå, kan man fra våreforsøk foreløpig konkludere med at tillegsfor ing av simler i siste halvdel av drektighetsperioden har effekt på kalvenes fødselsvekt, men at vektutviklingen for kalven er uavhengig av simlenes ernæringshistorie, om sistnevnte tilbys høyverdig ernæring etter kalving. Da små kalver etter underernærte simler viste høy dødelighet like etter fødselen, vil imidlertid tilleggsforing kunne øke avkastningen om det er mange unge simler i flokken. Resultatene fra Røros tyder imidlertid på at dette resultat normalt kan oppnås uten ekstra omkostninger gjennom et selektivt slakteuttak.

    Correlliansk wicca er en tradisjon innenfor wicca som baserer sin praksis på læren til High- Correll familien. Den correllianske wicca- tradisjonen ble grunnlagt av Caroline High- Correll. Correllianere anser seg selv for å være åpne for mange ulike livssyn og praksiser. De tror at det guddommelige kommer innenfra oss selv, og at religion eksisterer for å hjelpe oss til å finne det guddommelige i hver av oss, og ikke for å forsøke å erstatte denne guddommeligheten. Correllianere mener at alle...

    2009-01-01

    En metod för detektering och kvantifiering av gamma-hydroxysmörsyra (GHB) i urin med gaskromatografi (GC) är framtagen på Sahlgrenska universitetssjukhuset. Metoden är relativt unik då den inte kräver upparbetning i form av derivatisering, indunstning eller extraktion. Urinen surgörs med koncentrerad saltsyra och internstandard, gamma-valerolakton, tillsätts. GHB övergår då till laktonformen, gamma-butyrolakton (GBL). Därefter injiceras provet direkt på en GC-FID med en kapillärkolonn för gly...

Lærerens rolle blir ansett å være avgjørende for innlæring og styrking av denne ferdigheten, også i fag som naturfag og fysikk. Funnene fra to større forskningsprosjekter finansiert av Forskningsrådet ligger til grunn for valg av to case som vi presenterer og analyserer. I prosjektene har lesing og skriving vært undersøkt, og vi har i begge prosjekt sett på sammenhengen mellom de to ferdighetene. Den er så tett at vi derfor argumenterer for én grunnleggende ferdighet: literacy. Muntlighet inntar en viktig plass i undervisningen, og i artikkelen er det særlig lærerens rolle som modellerer og mediator som knyttes til betydningen av muntlig kommunikasjon.

    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.

  15. The role of variant histone H2AV in Drosophila melanogaster larval hematopoiesis.

    2017-04-15

    Replication-independent histone variants can replace the canonical replication-dependent histones. Vertebrates have multiple H2A variant histones, including H2AZ and H2AX that are present in most eukaryotes. H2AZ regulates transcriptional activation as well as the maintenance of gene silencing, while H2AX is important in DNA damage repair. The fruit fly Drosophila melanogaster has only one histone H2A variant (H2AV), which is a chimera of H2AZ and H2AX. In this study we found that lack of H2AV led to the formation of black melanotic masses in Drosophila third instar larvae. The formation of these masses was found in conjunction with a loss of the majority of the primary lymph gland lobes. Interestingly, the cells of the posterior signaling center were preserved in these mutants. Reduction of H2AV levels by RNAi knockdown caused a milder phenotype that preserved the lymph gland structure but that included precocious differentiation of the prohemocytes located within the medullary zone and the secondary lobes of the lymph gland. Mutant rescue experiments suggest that the H2AZ-like rather than the H2AX-like function of H2AV is primarily required for normal hematopoiesis. © 2017. Published by The Company of Biologists Ltd.

    Mitral regurgitation (MR) is associated with worse survival in those undergoing cardiac resynchronization therapy (CRT). Left ventricular (LV) lead position in CRT may ameliorate mechanisms of MR. We examine the association between a longer LV electric delay (QLV) at the LV stimulation site and MR reduction after CRT. QLV was assessed retrospectively in 426 patients enrolled in the SMART-AV study (SmartDelay Determined AV Optimization: A Comparison to Other AV Delay Methods Used in CRT). QLV was defined as the time from QRS onset to the first large peak of the LV electrogram. Linear regression and logistic regression were used to assess the association between baseline QLV and MR reduction at 6 months (absolute change in vena contracta width and odds of ≥1 grade reduction in MR). At baseline, there was no difference in MR grade, LV dyssynchrony, or LV volumes in those with QLV above versus below the median (95 ms). After multivariable adjustment, increasing QLV was an independent predictor of MR reduction at 6 months as reflected by an increased odds of MR response (odds ratio: 1.13 [1.03-1.25]/10 ms increase QLV; P=0.02) and a decrease in vena contracta width (P<0.001). At 3 months, longer QLV (≥median) was associated with significant decrease in LV end-systolic volume (ΔLV end-systolic volume -28.2±38.9 versus -4.9±33.8 mL, P<0.001). Adjustment for 3-month ΔLV end-systolic volume attenuated the association between QLV and 6-month MR reduction. In patients undergoing CRT, longer QLV was an independent predictor of MR reduction at 6 months and associated with interval 3-month LV reverse remodeling. These findings provide a mechanistic basis for using an electric-targeting LV lead strategy at the time of CRT implant. © 2016 American Heart Association, Inc.

    We present BVR photometric observations and several eclipsing times for AV Hya and DZ Cas from 2004 to 2011. Using the Wilson-Devinney method, the photometric solutions with hot spots were deduced from their asymmetric light curves. The results indicate that both stars are Algol-type binaries, whose mass ratio, q{sub ph}, and fill-out factor of the primary, f{sub 1}, are q{sub ph} = 0.255({+-} 0.002) and f{sub 1} = 81.2({+-} 0.2)% for AV Hya, and q{sub ph} = 0.093({+-} 0.003) and f{sub 1} = 98.7({+-} 0.3)% for DZ Cas. Based on all available light minimum times, it is discovered that the O - C curve of each star could be described by a light-time orbit overlying on a downward parabola. Their periods and amplitudes are P{sub 3} = 37.2({+-} 0.7) yr and A = 0fd0095({+-}0fd0006) for AV Hya, and P{sub 3} = 62.5({+-} 1.0) yr and A = 0fd0183({+-}0fd0007) for DZ Cas. Cyclic variations may result from the light-time effect due to the third body. The secular period decrease rates are dP/dt = -1.47({+-} 0.04) Multiplication-Sign 10{sup -7} days yr{sup -1} for AV Hya and dP/dt = -0.92({+-} 0.04) Multiplication-Sign 10{sup -7} days yr{sup -1} for DZ Cas. This may be interpreted using mass and angular momentum loss from the system. With decreasing period, the fill-out factor of the primary increases and it may finally fill its inner Roche lobe. Therefore, AV Hya and DZ Cas with a secular period decrease will evolve from semi-detached configurations into contact ones.

    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.

Based on all available light minimum times, it is discovered that the O - C curve of each star could be described by a light-time orbit overlying on a downward parabola. Their periods and amplitudes are P 3 = 37.2(± 0.7) yr and A = 0fd0095(±0fd0006) for AV Hya, and P 3 = 62.5(± 1.0) yr and A = 0fd0183(±0fd0007) for DZ Cas. Cyclic variations may result from the light-time effect due to the third body. The secular period decrease rates are dP/dt = -1.47(± 0.04) × 10-7 days yr-1 for AV Hya and dP/dt = -0.92(± 0.04) × 10-7 days yr-1 for DZ Cas.

    To investigate tau distribution in patients with corticobasal syndrome (CBS) using (18)F-AV-1451 PET. Six consecutively recruited patients with CBS and 20 age-matched healthy controls underwent 2 PET scans with (18)F-AV-1451 (for tau) and (18)F-florbetaben (for β-amyloid). We compared standardized uptake value ratio maps of the (18)F-AV-1451 PET images between the patients with CBS and controls. Compared to controls, patients with CBS exhibited asymmetrically increased (18)F-AV-1451 binding in the putamen, globus pallidus, and thalamus contralateral to the clinically more affected side and in the ipsilateral globus pallidus and dentate nucleus. Voxel-based comparison additionally showed asymmetrically increased (18)F-AV-1451 binding in the focal regions of the precentral gray and white matter and in the midbrain, predominantly in the contralateral side. (18)F-AV-1451 binding in the precentral white matter correlated with motor severity. (18)F-AV-1451 asymmetrically binds to motor-related subcortical gray and white matter structures in patients with CBS. This pattern corresponds to tau pathology distribution in postmortem studies, and motor deficit in patients with CBS may be associated with tau accumulation predominantly in the subcortical white matter underlying the motor cortex, leading to disruptions in motor-related networks. © 2017 American Academy of Neurology.

    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.

    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.

    Background and purpose: Combining statin and fibrate in clinical practice provides a greater reduction of triglycerides than either drug given alone, but the mechanism for this effect is poorly understood. Apolipoprotein AV (apoAV) has been implicated in triglyceride metabolism. This study was designed to investigate the effect of the combination of statin and fibrate on apoAV and the underlying mechanism(s). Experimental approach: Hypertriglyceridaemia was induced in rats by giving them 10% fructose in drinking water for 2 weeks. They were then treated with atorvastatin, fenofibrate or the two agents combined for 4 weeks, and plasma triglyceride and apoAV measured. We also tested the effects of these two agents on triglycerides and apoAV in HepG2 cells in culture. Western blot and reverse transcription polymerase chain reaction was used to measure apoAV and peroxisome proliferator-activated receptor-α (PPARα) expression. Key results: The combination of atorvastatin and fenofibrate resulted in a greater decrease in plasma triglycerides and a greater increase in plasma and hepatic apoAV than either agent given alone. Hepatic expression of the PPARα was also more extensively up-regulated in rats treated with the combination. A similar, greater increase in apoAV and a greater decrease in triglycerides were observed following treatment of HepG2 cells pre-exposed to fructose), with the combination. Adding an inhibitor of PPARα (MK886) abolished the effects of atorvastatin on HepG2 cells.

    One-third of eligible patients fail to respond to cardiac resynchronization therapy (CRT). Current methods to "optimize" the atrio-ventricular (A-V) interval are performed at rest, which may limit its efficacy during daily activities. We hypothesized that low-intensity cardiopulmonary exercise testing (CPX) could identify the most favorable physiologic combination of specific gas exchange parameters reflecting pulmonary blood flow or cardiac output, stroke volume, and left atrial pressure to guide determination of the optimal A-V interval. We assessed relative feasibility of determining the optimal A-V interval by three methods in 17 patients who underwent optimization of CRT: (1) resting echocardiographic optimization (the Ritter method), (2) resting electrical optimization (intrinsic A-V interval and QRS duration), and (3) during low-intensity, steady-state CPX. Five sequential, incremental A-V intervals were programmed in each method. Assessment of cardiopulmonary stability and potential influence on the CPX-based method were assessed. CPX and determination of a physiological optimal A-V interval was successfully completed in 94.1% of patients, slightly higher than the resting echo-based approach (88.2%). There was a wide variation in the optimal A-V delay determined by each method. There was no observed cardiopulmonary instability or impact of the implant procedure that affected determination of the CPX-based optimized A-V interval. Determining optimized A-V intervals by CPX is feasible. Proposed mechanisms explaining this finding and long-term impact require further study. ©2014 Wiley Periodicals, Inc.

    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.

  19. Apolipoprotein AV Accelerates Plasma Hydrolysis OfTriglyceride-Rich Lipoproteins By Interaction With Proteoglycan BoundLipoprotein Lipase

    Apolipoprotein A5 (APOA5) is associated with differences intriglyceride levels and familial combined hyperlipidemia. In genetically engineered mice, apoAV plasma levels are inversely correlated with plasmatriglycerides. To elucidate the mechanism by which apoAV influences plasma triglycerides, metabolic studies and in vitro assays resembling physiological conditions were performed. In hAPOA5 transgenic mice(hAPOA5tr), catabolism of chylomicrons and VLDL was accelerated due to a faster plasma hydrolysis of triglycerides by lipoprotein lipase (LPL).Hepatic VLDL and intestinal chylomicron production were not affected. The functional interplay between apoAV and LPL was further investigated by crossbreeding a human LPL transgene with the apoa5 knockout, and the hAPOA5tr to an LPL deficient background. Increased LPL activity completely normalized hypertriglyceridemia of apoa5 deficient mice,however, over expression of human apoAV modulated triglyceride levels only slightly when LPL was reduced. To reflect the physiological situation in which LPL is bound to cell surface proteoglycans, we examined hydrolysis in the presence or absence of proteoglycans. Without proteoglycans, apoAV derived either from triglyceride-rich lipoproteins, hAPOA5tr HDL, or a recombinant source did not alter the LPL hydrolysis rate. In the presence of proteoglycans, however, apoAV led to a significant and dose-dependent increase in LPL mediated hydrolysis of VLDL triglycerides. These results were confirmed in cell culture using a proteoglycan-deficient cell line.A direct interaction between LPL and apoAV was found by ligand blotting.It is proposed, that apoAV reduces triglyceride levels by guiding VLDL and chylomicrons to proteoglycans bound LPL for lipolysis.

    Litopenaeus vannamei is the most important farmed shrimp species globally, but its production is affected by several factors, including infectious disease. White spot syndrome virus (WSSV), in particular, causes significant shrimp losses. To understand the shrimp's immune response against WSSV, we cloned LvAV from L. vannamei and analyzed its expression pattern in different tissues, in addition to its expression following infection. We employed dsRNA and recombinant (r)LvAV to explore the potential role of LvAV in shrimp immunity when infected with WSSV. We find that LvAV is a C-type Lectin composed of 176 amino acids with a signal peptide and a specific C-type Lectin-type domain (CTLD). It shares 81% amino acid similarity with PmAV, an antiviral-like C-type Lectin from Penaeus monodom, and it is highly expressed in the hepatopancreas. Its expression is affected by infection with both WSSV and V. parahaemolyticus. Significantly, injection with rLvAV slowed WSSV replication, while injection with LvAV dsRNA initially led to enhanced virus propagation. Surprisingly, LvAV dsRNA subsequently led to a dramatic decrease in viral load in the later stages of infection, suggesting that LvAV may be subverted by WSSV to enhance viral replication or immune avoidance. Our results indicate that LvAV plays an important, but potentially complex role in the Pacific white shrimp's immune defense.

    The AV-reentrant tachycardia (AVRT) is a supraventricular tachycardia with an incidence of 1-3/1000. The pathophysiological basis is an accessory atrioventricular pathway (AP). Patients with AVRT typically present with palpitations, an on-off characteristic, anxiety, dyspnea, and polyuria. This type of tachycardia may often be terminated by vagal maneuvers. Although the clinical presentation of AVRT is quite similar to AV-nodal reentrant tachycardias, the correct diagnosis is often facilitated by analyzing a standard 12-lead ECG at normal heart rate showing ventricular preexcitation. Curative catheter ablation of the AP represents the therapy of choice in symptomatic patients. This article is the fourth part of a series written to improve the professional education of young electrophysiologists. It explains pathophysiology, symptoms, and electrophysiological findings of an invasive EP study. It focusses on mapping and ablation of accessory pathways.

    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

    Cerebrovascular deposition of amyloid-β, known as cerebral amyloid angiopathy (CAA), is associated with MRI findings of lobar hemorrhage, cerebral microbleeds, and cortical superficial siderosis. Although pathological studies suggest that tau may co-localize with vascular amyloid, this has not yet been investigated in CAA in vivo. Three patients with probable CAA underwent 11C-Pittsburgh Compound B (PiB) PET or 18F-florbetaben PET to evaluate amyloid burden, and 18F-AV-1451 PET to evaluate paired helical filament tau burden. Regions that had cerebral microbleeds or cortical superficial siderosis largely overlapped with those showing increased 18F-AV-1451. Our preliminary study raised the possibility that lobar cerebral microbleeds, and cortical superficial siderosis, which are characteristic markers of vascular amyloid, may be associated with local production of paired helical filament tau.

  10. Highly parallel implementation of sub-pixel interpolation for AVS HDTV decoder

    Institute of Scientific and Technical Information of China (English)

    Wan-yi LI; Lu YU

    2008-01-01

    In this paper,we propose an effective VLSI architecture of sub-pixel interpolation for motion compensation in the AVS HDTV decoder. To utilize the similar arithmetical operations of 15 luma sub-pixel positions,three types of interpolation filters are proposed. A simplified multiplier is presented due to the limited range of input in the chroma interpolation process. To improve the processing throughput,a parallel and pipelined computing architecture is adopted. The simulation results show that the proposed hardware implementation can satisfy the real-time constraint for the AVS HDTV (1 920×1 088) 30 fps decoder by operating at 108 M Hz with 38.18k logic gates. Meanwhile,it costs only 216 cycles to accomplish one macroblock,which means the B frame sub-pixel interpolation can be realized by using only one set of the proposed architecture under real-time constraints.

  11. Improved FFSBM Algorithm and Its VLSI Architecture for AVS Video Standard

    Institute of Scientific and Technical Information of China (English)

    Li Zhang; Don Xie; Di Wu

    2006-01-01

    The Video part of AVS (Audio Video Coding Standard) has been finalized recently. It has adopted variable block size motion compensation to improve its coding efficiency. This has brought heavy computation burden when it is applied to compress the HDTV (high definition television) content. Based on the original FFSBM (fast full search blocking matching),this paper proposes an improved FFSBM algorithm to adaptively reduce the complexity of motion estimation according to the actual motion intensity. The main idea of the proposed algorithm is to use the statistical distribution of MVD (motion vector difference). A VLSI (very large scale integration) architecture is also proposed to implement the improved motion estimation algorithm. Experimental results show that this algorithm-hardware co-design gives better tradeoff of gate-count and throughput than the existing ones and is a proper solution for the variable block size motion estimation in AVS.

  13. Integrating computation and visualization for biomolecular analysis: an example using python and AVS.

    Science.gov (United States)

    Sanner, M F; Duncan, B S; Carrillo, C J; Olson, A J

    1999-01-01

    One of the challenges in biocomputing is to enable the efficient use of a wide variety of fast-evolving computational methods to simulate, analyze, and understand the complex properties and interactions of molecular systems. Our laboratory investigates several areas including molecular visualization, protein-ligand docking, protein-protein docking, molecular surfaces, and the derivation of phenomenological potentials. In this paper we present an approach based on the Python programming language to achieve a high level of integration between these different computational methods and our primary visualization system AVS. This approach removes many limitations of AVS while increasing dramatically the inter-operability of our computational tools. Several examples are shown to illustrate how this approach enables a high level of integration and inter-operability between different tools, while retaining modularity and avoiding the creation of a large monolithic package that is difficult to extend and maintain.

    Backgrounds: "Off-target" binding in the basal ganglia is commonly observed in the (18)F-AV-1451 positron emission tomography (PET) studies of the elderly. We sought to investigate the relationship between this phenomenon in the basal ganglia and iron accumulation using iron-sensitive R2(*) magnetic resonance (MR) imaging. Methods: 59 healthy controls and 61 patients with Alzheimer's disease and mild cognitive impairment (AD/MCI) underwent (18)F-AV-1451 PET and R2(*) MR imaging studies. A correlation analysis was performed for age, (18)F-AV-1451 binding, and R2(*) values. Results: There was an age-related increase in both (18)F-AV-1451 binding in the basal ganglia and R2(*) values in the putamen in both the controls and AD/MCI patients. (18)F-AV-1451 binding in the basal ganglia increased with R2(*) 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. Copyright © 2017 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    To elucidate the relationship between cerebrospinal fluid (CSF) total-tau (T-tau) and phosphorylated tau (P-tau) with the tau PET ligand (18)F-AV-1451 in Alzheimer's disease (AD), we examined 30 cognitively healthy elderly (15 with preclinical AD), 14 prodromal AD, and 39 AD dementia patients. CSF T-tau and P-tau were highly correlated (R = 0.92, P AV-1451, and mainly in demented AD patients. (18)F-AV-1451, but not CSF T-tau or P-tau, was strongly associated with atrophy and cognitive impairment. CSF tau was increased in preclinical AD, despite normal (18)F-AV-1451 retention. However, not all dementia AD patients exhibited increased CSF tau, even though (18)F-AV-1451 retention was always increased at this disease stage. We conclude that CSF T-tau and P-tau mainly behave as biomarkers of "disease state", since they appear to be increased in many cases of AD at all disease stages, already before the emergence of tau aggregates. In contrast, (18)F-AV-1451 is a biomarker of "disease stage", since it is increased in clinical stages of the disease, and is associated with brain atrophy and cognitive decline. © 2017 The Authors.

    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.

    Full Text Available Artikkelen analyserer tros- og livssynsundervisning gjennomført i lærerutdanningens obligatoriske praksisopplæring ved Universitetet i Stavanger (UiS 2008-2009. Undervisningen inngikk i det ordinære valgemnet Religion, livssyn og etikk (RLE, og var samtidig integrert i FoU-prosjektet Religionsundervisning og mangfold (ROM. Målsetningen i ROM var å prøve ut en bestemt religionspedagogikk med tanke på håndtering av religiøst mangfold i skole og lærerutdanning. I lærerutdanningsdelen av prosjektet etablerte fem lærerstudenter, to praksislærere og to faglærere et praksisfellesskap som arbeidet individuelt og kollektivt i lys av aksjonsforskningsprisipper. Hver deltaker utviklet sitt didaktiske utprøvingsprosjekt med forankring i den valgte teorien, støttet av praksisfellesskapet. Praksisfellesskapets samhandling ble bl.a. dokumentert gjennom bruk av audio- og videoopptak. Spørsmålet som stilles er på hvilken måte den pedagogiske teorien som ble prøvd ut avdekket behov for bestemt fagkunnskap i undervisningen, og hvordan elevene responderte på denne RLE-undervisningen. Funn i videomaterialet som indikerer at valg av religionspedagogisk teori påvirket behovet for bestemt fagkunnskap i undervisningen, analyseres nærmere.

    Full Text Available Grunnskolelærerutdanningen har som mål å utdanne studenter med både aktør- og kommentatorkompetanse. Kommentatorkompetanse innebærer evnen til kritisk refleksjon. Planer, forskrifter og retningslinjer for grunnskolelærer-utdanningene fastslår at studentene skal ha kunnskaper om flerkultur og undervisning av minoritetsspråklige elever. Slik kompetanse er fortsatt etterspurt, også blant nyutdannede lærere.I denne undersøkelsen er “kritisk multikulturalisme” brukt som teoretisk tilnærming for å analysere gruppeintervjuer med lærerstudenter. Drøftingen inkluderer også hvordan begreper fra denne teoretiske tilnærmingen fungerer for å forstå lærerstudentenes kommentatorkompetanse. Kritisk multikulturalisme er opptatt av å gi en analyse av undertrykking og institusjonalisering av ulike maktrelasjoner innen utdanning. Begreper som er særlig framtredende, er systemmakt, definisjonsmakt og avmakt. Empirien er en del av et større forskningsprosjekt ved UiS, som studerer praksis i grunnskolelærerutdanningen.Undersøkelsen viser at lærerstudentene viser oppmerksomhet og grad av kritisk kommentatorkompetanse når det gjelder systemnivå og pedagogiske praksiser, men ikke har nødvendigvis tilstrekkelig kunnskap om lover og regler for opplæringen. De savner mer oppmerksomhet på temaet innen lærerutdanningen, særlig konkret didaktikk. Funn i materialet indikerer at det ville være av betydning med en dypere forståelse og mer faglige begreper som grunnlag for refleksjon.Analysebegrepene fra kritisk multikulturalisme kan bidra til å sette studentenes utsagn inn i en større sammenheng og peke på potensielt diskriminerende diskurser, men fanger ikke alt studentene er opptatt av. Dette er et område som det ikke er mye forskning på i Norge, artikkelen er et bidrag til økt kunnskap om flerkultur i grunnskolelærerutdanningene.Nøkkelord: lærerstudenter, flerkultur, flerspråklige elever, kritisk multikulturalisme Abstract

  3. Conserved hypothetical BB0462 protein enhances the transcription activity of oppAV promoter

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Borrelia burgdorferi BB0462 ORF encodes an unknown functional protein with 110 amino acids.A BLAST search in protein databases and the secondary structure being predicted by the program JUFO showed that the conserved hypothetical BB0462 protein was similar to the members of the YbaB protein family in both amino acid composition and protein structure.The co-transformation of BB0462 ORF and oppA upstream regulation DNA into E.coli host cells and β-galactosidase activity assay demonstrated that the BB0462 protein enhanced the transcriptional activity of the oppAV promoter,but does not affect those of oppAⅠ,Ⅱ,Ⅲ and Ⅳ promoters.Analysis of DNA retardation and competitive repression also confirmed that the BB0462 protein bound to the 409 bp upstream regulation DNA fragment close to the initiation codon of the oppAV gene.All data in our study suggested that the BB0462 protein was involved in the transcriptional regulation of the oppAV gene

    VDD pacing provides the physiological benefits of atrioventricular synchronous pacing with the convenience of a single lead system, but is hampered by uncertainty regarding long term atrial sensing and potential development of sinus node disease. To examine the long-term reliability and complication rates of VDD pacing, we compared the outcome of 112 consecutive patients (age 70 +/- 13 years, 59% men) with symptomatic AV block who received a single pass bipolar VDD system, to 80 patients (age 63 +/- 16 years, 70% men) who received DDD pacing for the same indication. All patients were judged to have intact sinus node function based on submitted ECGs and monitoring results at the time of implant. Implant time was reduced in VDD patients compared to DDD patients (63 +/- 20 vs 97 +/- 36 minutes, P DDD patients compared to 3 (3%) VDD patients (P = 0.15). The implant P wave was lower with VDD pacing compared to DDD patients (2.91 +/- 1.48 vs 4.0 +/- 1.7 mv, P DDD patients. Physiological atrioventricular activation was maintained in 94%-99% of beats throughout the follow-up period in the VDD group. VDD pacing is an excellent strategy for treatment of patients with symptomatic AV block. The lower cost, high reliability, and abbreviated implantation time suggest that VDD pacing is a viable alternative to DDD pacing in patients with high degree AV block and normal sinus node function.

    Mungbean yellow mosaic India virus (MYMIV) is a whitefly-transmitted begomovirus with a bipartite genome. We investigate the functions of the MYMIV-AV2 protein, the open reading frame present upstream of the coat protein gene in DNA A component. The ability of MYMIV-AV2 mutants to replicate, spread and cause symptoms in legume hosts, blackgram, cowpea and French bean was analysed. Plants agroinoculated with mutants K73R, C86S and the double mutant C84S, C86S showed increase in severity of symptoms compared with the wild type. However, mutants W2S and H14Q,G15E caused marked attenuation of symptoms. While the double mutants C84S,C86S caused a 50-fold increase in double-stranded supercoiled and single-stranded DNA accumulation, the mutations W2S and H14Q,G15E showed a decrease in double-stranded supercoiled and single-stranded viral DNA accumulation. Because AV2 mutants affect the ratio between open circular and supercoiled DNA forms, we hypothesize that these mutations may modulate the functions of the replication initiation protein.

    2017-07-13

    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.

  7. A CODING SCHEME USING GLOBAL MOTION ESTIMATION FOR AVS P-FRAME

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Block matching has been used for motion estimation and motion compensation in the Audio and Video Standard (AVS) for years. While having an acceptable performance in describing motion between frames, it requires quite a few bits to represent the motion vectors. In certain circumstances, the use of global motion estimation and compensation would perform equally well or even better than the block matching in terms of motion accuracy, while it results in the coding of global motion model parameters. In this letter, we modify an AVS coder by adding (1) six global motion model parameters to the frame header, and (2) mode selection among INTRA, SKIP, INTER-16×16,INTER-16×8, INTER-8×16, INTER-8×8, and Global Motion Compensation (GMC) modes by Lagrange optimal rate-distortion criteria. Simulation results demonstrate that over 0.1dB improvement in PSNR is obtained compared to the AVS coder for an average coded P-frame with the same bitrate.

  8. Coding efficiency of AVS 2.0 for CBAC and CABAC engines

    In this paper we compare the coding efficiency of AVS 2.0[1] for engines of the Context-based Binary Arithmetic Coding (CBAC)[2] in the AVS 2.0 and the Context-Adaptive Binary Arithmetic Coder (CABAC)[3] in the HEVC[4]. For fair comparison, the CABAC is embedded in the reference code RD10.1 because the CBAC is in the HEVC in our previous work[5]. The rate estimation table is employed only for RDOQ in the RD code. To reduce the computation complexity of the video encoder, therefore we modified the RD code so that the rate estimation table is employed for all RDO decision. Furthermore, we also simplify the complexity of rate estimation table by reducing the bit depth of its fractional part to 2 from 8. The simulation result shows that the CABAC has the BD-rate loss of about 0.7% compared to the CBAC. It seems that the CBAC is a little more efficient than that the CABAC in the AVS 2.0.

    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.

    Full Text Available Abstract Background Over the past two decades more than fifty thousand unique clinical and biological samples have been assayed using the Affymetrix HG-U133 and HG-U95 GeneChip microarray platforms. This substantial repository has been used extensively to characterize changes in gene expression between biological samples, but has not been previously mined en masse for changes in mRNA processing. We explored the possibility of using HG-U133 microarray data to identify changes in alternative mRNA processing in several available archival datasets. Results Data from these and other gene expression microarrays can now be mined for changes in transcript isoform abundance using a program described here, SplicerAV. Using in vivo and in vitro breast cancer microarray datasets, SplicerAV was able to perform both gene and isoform specific expression profiling within the same microarray dataset. Our reanalysis of Affymetrix U133 plus 2.0 data generated by in vitro over-expression of HRAS, E2F3, beta-catenin (CTNNB1, SRC, and MYC identified several hundred oncogene-induced mRNA isoform changes, one of which recognized a previously unknown mechanism of EGFR family activation. Using clinical data, SplicerAV predicted 241 isoform changes between low and high grade breast tumors; with changes enriched among genes coding for guanyl-nucleotide exchange factors, metalloprotease inhibitors, and mRNA processing factors. Isoform changes in 15 genes were associated with aggressive cancer across the three breast cancer datasets. Conclusions Using SplicerAV, we identified several hundred previously uncharacterized isoform changes induced by in vitro oncogene over-expression and revealed a previously unknown mechanism of EGFR activation in human mammary epithelial cells. We analyzed Affymetrix GeneChip data from over 400 human breast tumors in three independent studies, making this the largest clinical dataset analyzed for en masse changes in alternative mRNA processing

    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

    The aim of this study was to systematically review the medical literature to evaluate the impact of AV nodal ablation in patients with heart failure and coexistent atrial fibrillation (AF) receiving cardiac resynchronization therapy (CRT). CRT has a substantial evidence base in patients in sinus rhythm with significant systolic dysfunction, symptomatic heart failure, and prolonged QRS duration. The role of CRT is less well established in AF patients with coexistent heart failure. AV nodal ablation has recently been suggested to improve outcomes in this group. Electronic databases and reference lists through September 15, 2010, were searched. Two reviewers independently evaluated citation titles, abstracts, and articles. Studies reporting the outcomes after AV nodal ablation in patients with AF undergoing CRT for symptomatic heart failure and left ventricular dyssynchrony were selected. Data were extracted from 6 studies, including 768 CRT-AF patients, composed of 339 patients who underwent AV nodal ablation and 429 treated with medical therapy aimed at rate control alone. AV nodal ablation in CRT-AF patients was associated with significant reductions in all-cause mortality (risk ratio: 0.42 [95% confidence interval: 0.26 to 0.68]), cardiovascular mortality (risk ratio: 0.44 [95% confidence interval: 0.24 to 0.81]), and improvement in mean New York Heart Association functional class (risk ratio: -0.52 [95% confidence interval: -0.87 to -0.17]). AV nodal ablation was associated with a substantial reduction in all-cause mortality and cardiovascular mortality and with improvements in New York Heart Association functional class compared with medical therapy in CRT-AF patients. Randomized controlled trials are warranted to confirm the efficacy and safety of AV nodal ablation in this patient population. © 2012 American College of Cardiology Foundation.

    BACKGROUND The arteriovenous (AV) loop model enables axial vascularization to gain a functional microcirculatory system in tissue engineering constructs in vivo. These constructs might replace surgical flaps for the treatment of complex wounds in the future. Today, free flaps are often exposed to high-dose radiation after defect coverage, according to guideline-oriented treatment plans. Vascular response of AV loop-based constructs has not been evaluated after radiation, although it is of particular importance. It is further unclear whether the interposed venous AV loop graft is crucial for the induction of angiogenesis. MATERIAL AND METHODS We exposed the grafted vein to a single radiation dose of 2 Gy prior to loop construction to alter intrinsic and angio-inductive properties specifically within the graft. Vessel loops were embedded in a fibrin-filled chamber for 15 days and radiation-induced effects on flow-mediated vascularization were assessed by micro-CT and two-dimensional histological analysis. RESULTS Vessel amount was significantly impaired when an irradiated vein graft was used for AV loop construction. However, vessel growth and differentiation were still present. In contrast to vessel density, which was homogeneously diminished in constructs containing irradiated veins, vessel diameter was primarily decreased in the more peripheral regions. CONCLUSIONS Vascular luminal sprouts were significantly diminished in irradiated venous grafts, suggesting that the interposing vein constitutes a vital part of the AV loop model and is essential to initiate flow-mediate angiogenesis. These results add to the current understanding of AV loop-based neovascularization and suggest clinical implications for patients requiring combined AV loop-based tissue transfer and adjuvant radiotherapy.

    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”.
