Popular Abstract in Swedish Stamceller är unika celler som har möjlighet att både förnya sig själva och ge upphov till en mängd mogna celler. Den ultimata stamcellen är det befruktade ägget, som är den cell som efter omfattande celldelning kommer att ge upphov till alla vävnader och celler i den färdigutvecklade kroppen. Dessa celler kallas därför pluripotenta. Även i den färdigutvecklade kroppen Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. Because of these features, HSCs are also the basis for bone marrow transplantation regimens for tr

Systems based on bag-of-words models from image features collected at maxima of sparse interest point operators have been used successfully for both computer visual object and action recognition tasks. While the sparse, interest-point based approach to recognition is not inconsistent with visual processing in biological systems that operate in 'saccade and fixate' regimes, the methodology and emph

EU anses av många ha en av världens strängaste regleringar för dataskydd. Unionen och dess medlemsstater har dock, likt resten av världen, i och med den globala och tekniska utvecklingen ett intresse av att kunna överföra personuppgifter till tredjeländer. I syfte att balansera det höga integritetsskyddet mot intresset av att överföra personuppgifter till tredjeland, finns i dataskyddsförordningenThe EU is by many considered to have one of the world's strictest regulations for data protection. However, the Union and its Member States, like the rest of the world, have an interest in being able to transfer personal data to third countries due to global and technological developments. In order to balance the high level of privacy protection against the interest in transferring personal da

The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. Despite restoration projects already being i

The three works analyzed here were published at the culmination of Swedish romanticism. The strange mixture of the high and the low, the sacred and the profane that is typical for them has been an interesting challenge for literary scholars. For instance, in older research one sometimes spoke of poor handwork, or bad taste of the writers or it was explained that these works were a stage between th

År 2000 satte den Europeiska Unionen ett strategiskt mål att bli en större, mer konkurrenskraftig ekonomisk region med stark tillväxt för ekonomi och arbetskraft. En viktig komponent i att nå detta mål är att utveckla den inre marknaden och stödja den fria rörligheten för varor, kapital, tjänster och personer inom den Europeiska Unionen. Kommissionen har identifierat skillnader i Medlemsstaternas In 2000, the European Union set out the strategic goal to become a more competitive, stronger economic region with sustainable growth in terms of economy and jobs. An important part in achieving this goal is the complete establishment of the internal market to fully promote freedom of movement of goods, capital, services and people within the European Union. The Commission has identified diversity

It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. The goal of the present project was to investigate attractiveness of different species of flowers to the silver Y moth, to identify constituents of vola

Popular Abstract in Swedish Järn har den kemiska beteckningen Fe från latinskans ferrum. Det är det fjärde vanligaste ämnet i världen och utgör ca en femtedel av jordskorpan. Trots det kan både djur och växter ha järnbrist. Hur kan detta vara möjligt? Problemet är egentligen inte förekomsten av järn utan att järnet som vi och alla andra organismer behöver har oxidationstillståndet Fe(II) medan detIt is of vital importance to understand the systems for iron metabolism and this thesis contributes to this by providing insights into the structure and function of the acquisition and homeostasis of iron. The two proteins that have been primarily investigated are a ferric reductase from Arabidopsis thaliana called FRO2 and a mitochondrial iron chaperone from Saccharomyces cerevisiae called fratax

Popular Abstract in Swedish Så gott som alla metaller reagerar vid normala omständigheter med syret i luften och oxideras, vilket förändrar materialets egenskaper. T.ex. rostar järn efter hand, något som alla bilägare är bittert medvetna om. Oxider behöver dock inte vara negativa, utan kan även fungera som barriärer mot fortsatt korrosion, isolerande skikt i mikroelektronikkomponenter m.m. FöljaktThe oxidation of Rh, Pd and Pt is studied under conditions ranging from ultra high vacuum to ambient pressures, with emphasis on a complete understanding of the geometry of the various oxide structures found. The investigations use a combination of various experimental methods, including high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction and scannin

BACKGROUND: The Emergency Department (ED) is a common route to hospitalization for critically ill and older adults. Older patients are admitted to hospital at a higher rate and have longer length of stay (LOS) when hospitalized. To be able to confront an increasing aging population, meet their medical needs and influence rising costs of health care, there is a need to focus on the older population

Den globala jordbruksproduktionen har de senaste fem decennierna nästan tredubblats. Produktionsökningen beror på ett allt intensivare jordbruk samt konvertering av naturliga ekosystem till jordbruksmark. Intensifieringen av jordbruket har skett genom ökad användning av högavkastande grödor, mekanisering, bevattning, konstgödsel och bekämpningsmedel. Både intensivare jordbruk och expansionen av joGlobal agricultural production almost tripled within the last five decades. The production increase wasbased on expanding cropland and pastures, as well as the intensification of agriculture, including increased use ofhigh yielding crop varieties, machinery, irrigation, artificial fertilisers, and pesticides. Both, agriculturalintensification and the expansion of agricultural land-use lead to envi

Avhandlingen, som består av fyra delstudier, är en femårsuppföljning av kvinnliga missbrukare, som var tvångsomhändertagna på Lunden mellan januari 1997 och december 2000, och som genomgick en omfattande utredning. Klienterna har systematiskt utretts med psykologiska och neuropsykologiska test i samarbete med personal och Lundens psykiater. Test och skattningsskalor som använts är standardiserade The study focus is a sample of women with drug dependence admitted to compulsory treatment according to the Swedish act of care for drug abusers (LVM, 1988:870) and according to the act of care for young persons (LVU, 1990:52). From a cohort consecutively admitted to residential treatment at Lunden between 1997 and 2000, a sample of 132 women was selected for a five year follow-up. They were evalu

Starch is a common ingredient in many products, influencing properties such as viscosity, stability, sensory properties and appearance. These properties and how they change with time in the process called retrogradation are dependent on the structure of starch and its interaction with other components such as lipids and proteins. Lipids, which are present in many starches and products, play an imp

Geographic accessibility to services is important. Having a grocery store and a school nearby are important living conditions and having a rescue station close by could be a life-saver. Costs for transportation are high and are predicted to increase, new environmental demands are being imposed on transportation and rationalizations are centralizing public and commercial services. These facts make

We have shown recently that PrkC, which is involved in developmental processes in Bacillus subtilis, is a Ser/Thr kinase with features of the receptor kinase family of eukaryotic Hanks kinases. In this study, we expressed and purified from Escherichia coli the cytoplasmic domain of PrkC containing the kinase and a short juxtamembrane region. This fragment, which we designate PrkCc, undergoes autop

We describe a method and device (< 1.2 g) for recording, processing and storing data about activity and location of individuals of free-living songbirds throughout the annual cycle. Activity level was determined every five minutes from five 100 ms samples of accelerometer data with 5 s between the sampling events. Activity levels were stored on an hourly basis throughout the annual cycle, allowing

Since the invention of the first car available to masses, the 1908 Ford Model T, technology has advanced towards making car travel safer for occupants and bystanders. In recent years, wireless communication has been introduced in the vehicular industry as a means to avoid accidents and save lives.Wireless communication may sometimes be challenging due to obstacles in the physical world that intera

We discuss the properties of Hα emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely belonging to stars in young open clusters. Automated fits using two independent Gaussian profiles and a third component that accounts for the nebular emission allow us to discern distinct morphological types of Hα line pr

Continuous exposure of DDT1 MF-2 smooth muscle cells to 10-100 μM norepinephrine results in a dramatic attenuation of the ability of norepinephrine to stimulate inositol phospholipid hydrolysis via α1-adrenergic receptors (α1-AR). In addition to the functional desensitization, norepinephrine exposure also reduces the number of accessible cell surface α1-AR as assayed by [3H]prazosin binding at 4°

The aim of the study was to examine the role culture plays in caregiver’s pain-related parent behaviors. This study used a cross-cultural survey design with a convenience sample of caregivers of 6-12-year-old children (N = 547) living in Canada (n = 183), Iceland (n = 184), or Thailand (n = 180). A team-translation approach included psychometric assessment and confirmatory factor analysis, ensurin
