Objectives Nuchal translucency (NT) screening increases antenatal detection of Down syndrome (DS) compared to maternal age-based screening. We wanted to determine if a change in policy for prenatal diagnosis would result in fewer babies born with DS. Methods A total of 39572 pregnant women were randomized to a scan at 12-14 gestational weeks including NT screening for DS (12-week group) or to a sc

Popular Abstract in Swedish Som en följd av de senaste årens förtätningstrend har stadens täthet blivit en aktuell stadsbyggnadsfråga. Förtätning är ett komplext fenomen som berör en rad centrala egenskaper hos staden. Förtätning är också en kontroversiell stadsbyggnadsstrategi. Det är motsättningen mellan förtätning och friytor som den här avhandlingen tar sin utgångspunkt i. Krymper mellanrummenThe new interest in density displayed by professional town planners and town-planning researchers is related to the present densification of the urban environment in many towns and cities. Research on densification is primarily concerned with the link between urban form and sustainable development. The point of departure of this thesis is to consider what a denser housing environment will mean to

Popular Abstract in Swedish Vi har de senaste decennierna sett stora förändringar vad gäller kontroll och tillgänglighet i det offentliga rummet. Både forskning och planering är i starkt behov av begrepp och teori för att klargöra den byggda miljöns roll i detta sammanhang. I avhandlingen utvecklas redskap för att beskriva och belysa arkitekturens roll i upprättandet av olika slags territorier inoThe point of departure of this dissertation is a consideration of the problems in the field of architecture, of conceptualizing and addressing aspects of the complex relationship between architectural form and use. The aim of the thesis is to create conditions for a discussion on architectural design and territorial power relations within the context of everyday life, and more specifically to inve

Popular Abstract in Swedish Den offentliga sektorn har vuxit drastiskt under det senaste århundradet och utgör idag en stor del av ekonomin i många västländer. Givet storleken på den offentliga sektorn och dess potentiella inflytande över såväl enskilda individer som samhälle är studier som dokumenterar effekterna av den offentliga sektorn värdefulla. Denna avhandling "Den Offentliga Sektorns BegrThe size of government has increased dramatically over the last century. Given the magnitude of government involvement in the economy and the potential influence it has on individuals as well as the economy, studies documenting the effects of government size may offer particularly timely insights. This thesis addresses some of these issues. Chapter two and three deal with welfare reform. Welfare

We report the application of mid-infrared polarization spectroscopy (IRPS) for detection of nascent CO2 and H2O in atmospheric pressure flames. The recorded IRPS spectra demonstrated both the quantitative nature of the method and the suppression of strong infrared emission from flames. In spite of the high line-density of the hot polyatomic ro-vibrational spectrum, lines belonging to different CO2

Bacillus subtilis YtlP is a protein that is predicted to belong to the bacterial and archael 2'-5' RNA-ligase family. It contains 183 residues and two copies of the HXTX sequence motif conserved among proteins belonging to this family. In order to determine the structure of YtlP and to compare it with the paralogue YjcG and identified 2'-5' RNA ligases, the gene ytlP was amplified from B. subtilis

PURPOSE: To investigate retrobulbar blood flow velocities and the effects of topical timolol treatment in eyes with newly detected, previously untreated open angle glaucoma or ocular hypertension. METHODS: Fifteen eyes with open angle glaucoma (OAG) and 12 eyes with ocular hypertension (OH), in the same number of patients, all untreated and newly detected, were examined with colour Doppler imaging

We examined the structure of the affinity-labeled insulin receptors in rat brain, rat liver, and human IM-9 lymphocytes using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In gels run under reducing conditions, the alpha-subunit of the insulin receptor in brain had an apparent Mr of 127,000 distinctly lower than that seen in both rat liver and human lymphocytes (apparent Mr = 136,000)

Cost-of-illness studies have shown diabetes to be associated with substantial direct and indirect costs, accounting for 5-6 percent of total health care expenditure. In a Swedish study, where total costs were divided into costs due to management of diabetes and costs due to complications, the total annual cost to the community was estimated to be SEK 5.7 billion in 1994, costs due to complications

Twenty-eight haemodialysis patients were randomized to L-carnitine, 2 g i.v. three times a week, and saline over a 6-week period. No obvious deficiency of carnitine was found in vastus lateralis with a median value of 12.9 mmol/kg dry weight; range 6.2-21.4. Female patients had lower total plasma carnitine compared to female controls, p less than 0.002, whereas no decrease was found in males. No r

The quality of test is highly related to the number of faults that can be detected during the testing (fault coverage) and the defect probability of each testable unit. High test quality is reached by applying an excessive number of good test vectors, however, such a high test data volume can be problematic to fit in the ATE's (automatic test equipment) limited memory. We therefore propose, for co

In 1996, national guidelines for the care and treatment of patients with diabetes mellitus were drawn up by specialists, in collaboration with representatives of the patient organisation, diabetes nurses, the professional associations of various medical specialties and central authorities. The national programme is divides into three parts: summarised information for decision-makers, clinical guid

Popular Abstract in Swedish I hjärnan finns många olika typer av nervceller. De använder sig av olika signalsubstanser, kallade neurotransmittorer, för att kommunicera med andra nervceller. En viss typ av nervceller använder neurotransmittorn dopamin. Dopaminceller finns på många ställen i hjärnan men de flesta ligger i mellanhjärnan i ett par olika cellgrupper som var och en skickar signaler tillParkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. Clinical trials have shown that cell replacement therapy, where dopaminergic neuroblasts derived from fetal vent

This paper argues that expected utility theory for actions in chancy environments should be formulated in terms of centered chances. The subjective expected utility of an option A may be seen as a weighted sum of the utilities of A in different possible worlds, with weights being the credences that the agent assigns to these worlds. The utility of A in a given world is then definable as a weighted

Changes in agricultural management have been identified as the most probable cause for the decline of Skylark (Alauda arvensis) populations in Europe. However, parasitic infections have not been considered as a possible factor influencing this process. Four hundred and thirty-four Skylarks from the Southern Italy and the Netherlands were screened for haemosporidian parasites (Haemosporida) using t
