Popular Abstract in Swedish Inom området diagnostisk nuklearmedicin används radioaktiva läkemedel som ges (administreras) till patienterna i syfte att diagnostisera ett antal olika sjukdomstillstånd. Då man tar fram nya radioaktiva läkemedel för användning inom diagnostisk nuklearmedicin handlar det många gånger om att uppskatta mängden av ett visst upptag av radiofarmakat i olika organ och vävnadAn essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not. It is also important that the biokinetics and dos

Popular Abstract in Swedish Avhandlingen består av 5 delstudier. Fyra belyser olika aspekter av alkoholproblem hos kvinnor jämfört med män. Ett delarbete grundar sig på en studiepopulation av endast kvinnor. Undersökningsgrupperna består av såväl patienter som individer från den allmänna befolkningen. De två första studierna utgår från kvinnor och män i Malmö födda 1941, som undersöktes vid 42-årThis thesis presents data relating to gender differences of problem drinking. The aim was to increase the knowledge of characteristics of female problem drinking to enhance identification efficiency. Alcoholic patients, 214 women and 420 men, and subjects from the general population, 2939 women and 1880 men, in Malmö, Sweden were studied between 1983-1995. Lifetime prevalence rates of problem dri

Popular Abstract in Swedish Magnetresonanstomografi (MRT) är en metod för framställning av bilder av kroppen och av sjukliga förändringar i kroppen. När metoden introducerades ansågs den utomordentligt goda inbyggda vävnadskontrasten vara tillräcklig för att särskilja olika sjukliga förändringar, speciellt i hjärnan. Det har emellertid visat sig att förmågan att upptäcka sjukliga förändringar är oAims of the study The aims of this study using Gadodiamide injection were to investigate: · Whether Gadodiamide injection was comparable to Gd-DTPA for the enhancement of CNS lesions. · The contrast effect at different field strengths. · The effective time-window for the enhancement of blood-brain barrier damage. · The relations between the concentration of contrast agent and enhancement in p

Supportive legislation and improving technologies are making bioenergy an increasingly attractive energy source for Europe both economically and environmentally. However, abundant resources remain untapped across many member states in the European Union (EU). The Bioenergy Network of Excellence (NoE) entitled Overcoming Barriers to Bioenergy in Europe is charged with the task to identify critical

Cationic polymers in the form of anion-exchange membranes (AEMs) may enable a route towards low platinum or even platinum-free alkaline membrane fuel cells with the potential to oxidize more complex fuels than hydrogen and methanol [1-4]. The main challenges for the AEMs are currently to enhance the alkaline stability of the cationic group and to improve the ion conductivity. In this context, ther

How can qualitative, ethnographic and emotional aspects from probe users be mapped at the same time as they get something meaningful in return? The emphasis is here on intellectual rewards during probe work rather than future good designs that in a long term perspective can be beneficial for the probe user. This case study has elaborated the traditional use of cultural probes [1] with a selection

Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con

In this work, we present a ridged, microfabricated, force sensor that can be used to investigate mechanical interactions between cells exhibiting contact guidance and the underlying cell culture substrate, and a proof-of-function evaluation of the force sensor performance. The substrates contain arrays of vertical pillars between solid ridges that were microfabricated in silicon wafers using photo

We show that the boundary conditions entering in the definition of the self-adjoint operator Delta(A,B) describing the Laplacian plus afinite number of point interactions are local if and only if the corresponding wave equation phi = Delta(A,B)phi has finite speed of propagation.

A mathematical model for through drying of paper at constant pressure drop was developed. The model is based on physical properties; hence, basis weight, pressure drop, drying air temperature, pore size distribution, initial gas fraction, and tortuosity are important input parameters to the model. The model was solved for different combinations of the variables basis weight, drying air temperature

Membrane electrode assemblies (MEAs) with a sulfonated polysulfone (sPSU) as the proton-conducting phase were fuel cell evaluated at varying temperatures in over-humidified conditions. The sPSU was prepared by a direct polycondensation involving a commercially available sulfonated naphthalene diol monomer. The gas diffusion electrodes (GDEs) and MEAs were successfully fabricated and a thorough mor

Protein H, a molecule expressed at the surface of some strains of Streptococcus pyogenes, has affinity for the constant (IgGFc) region of immunoglobulin (Ig) G. In absorption experiments with human plasma, protein H-sepharose could absorb not only IgG but also albumin from plasma. The affinity constant for the reaction between albumin and protein H was 7.8 x 10(9) M-1, which is higher than the aff

Objective: To assess factors for progression in the Early Manifest Glaucoma Trial (EMGT), including the effect of EMGT treatment. Setting/Participants: Two hundred fifty-five open-angle glaucoma patients randomized to argon laser trabeculoplasty plus topical betaxolol or no immediate treatment (129 treated; 126 controls) and followed up every 3 months. Methods: Progression was determined by perime

We investigated whether renal function and microalbuminuria are independent predictors and whether any interaction exists between them, regarding future cardiovascular disease in hypertensive patients (n=10 881) followed for 4.5 years. The primary end points (PEs) were fatal and nonfatal myocardial infarction and stroke and other cardiovascular deaths. Creatinine and glomerular filtration rate (GF

Objective The suspect carcinogens, heterocyclic amines (HAAs), found in well-done meat require host-mediated metabolic activation before inducing DNA mutations. The role of SULT1A1 and of NAT2 on the activation of HAAs suggests that NAT2 rapid acetylator genotype and SULT1A1 allele variants can have an effect on HAA carcinogenicity. Methods Data were collected as part of a case-control study neste
