The effect of various antipsychotics during pregnancy has repeatedly been studied, but for most atypical antipsychotics, only little information is available. We identified from the Swedish Medical Birth Register 2908 women who had reported the use of any antipsychotic or lithium in early pregnancy and studied malformation rates with data also from the Register of Congenital Malformations and the

Recent research has identified promising targets for therapeutic interventions aimed at modulating the inflammatory response in sepsis. Herein, the authors describe mechanisms involved in the clearance of pathogen toxin from the circulation and potential interventions aimed at enhancing clearance mechanisms. The authors also describe advances in the understanding of the innate immune response as p

Popular Abstract in Swedish Den teoretiska beskrivningen av materians minsta beståndsdelar, den så kallade standardmodellen (SM), överenstämmer med oerhörd noggrannhet med de många och avancerade partikelfysik-experiment som utförts världen över. Trots denna överenstämmelse finns problematiska aspekter hos SM som gör att den inte kommer kunna beskriva fysikaliska fenomen vid högre energier, som änA search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb^-1 was used in the single photon analysis and 450 pb^-1 in the chargino search. Center-of-mass energies up to 209 GeV were ex

Popular Abstract in Swedish För många cancerpatienter är strålbehandling ett viktigt behandlingsalternativ. En framgångsrik behandling kräver att den absorberade dosen till patienten kan ges med stor noggrannhet. Detta eftersom en liten avvikelse i absorberad dos kan påverka behandlingens resultat. Strålbehandling sker idag med avancerad teknik och utrustning där osäkerheterna i varje led i behandThis thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm.

This paper verified the macro-to-mini-scale criterion BoRe10.5=200 because data points where BoRe10.5≤200 and BoRe10.5>200 show very different trends for the entire database (1672 data points). Boiling number at critical heat flux (Blchf) decreases greatly with heated length-to-diameter ratio (Lh/dhe) when Lh/dhe is small while a relatively smooth trend occurs with large Lh/dhe values. The paper p

The overall aim of this composite thesis, consisting of five articles, is to develop concepts for furthering the understanding of small business managers´ handling of finance. The main contribution is the development of a conceptual understanding of so-called financial bootstrapping behavior in small businesses (referring to the use of methods for minimizing and/or eliminating the need for financi

Popular Abstract in English Nanoscience and nanotechnology have existed in this world before scientists actually coined the terms. Nature around us and human beings themselves are all made of nanomaterials (1-100 nm), such as DNA, proteins, liposomes, and enzymes. These building blocks possess molecular recognition properties, resulting in their self-assembly to form various two- and three-dimensiMolecularly imprinted polymers (MIPs) are artificial receptors made by imprinting template molecules in a polymer matrix followed by their removal through washing to obtain a specific and selective template cavities. This property of the MIPs have made them a very efficient material for diverse applications such as chromatography, purification, drug sensing, etc. Recently, zero-dimensional polymer

Objective: The aim of this study was to test the feasibility and accuracy of transthoracic Doppler echocardiography measurement of coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD) territory in the clinical setting of the acute coronary syndrome. Methods: Transthoracic Doppler echocardiography measurements of CFR were made in 42 consecutive patients in the distal LA

Evaluation of various methods in clinical practice is often based on interpretations by two or more observers. Such data need to be analysed with correct statistics, or the results and conclusions may be misleading. In this study, the use of measures of agreement for ordinal data in five international nursing journals is reviewed and various methods for measuring agreement are presented and discus

Induction of altered phenotypes during development in response to environmental input involves epigenetic changes. Phenotypic traits can be passed between generations by a variety of mechanisms, including direct transmission of epigenetic states or by induction of epigenetic marks de novo in each generation. To distinguish between these possibilities we measured epigenetic marks over four generati

Popular Abstract in Swedish Hematopoes är bildandet av blodceller. Blodbildningen har sin utgångspunkt i benmärgen i stamceller vilka ger upphov till i huvudsak åtta typer av blodceller med var sina specifika uppgifter. De röda blodkropparna transporterar syre från lungorna ut i hela kroppen,blodplättar har sin främsta funktion i att initiera stopp av en blödning,granulocyter och makrofager äter uA common feature in myeloid leukemia is suppression of normal hematopoiesis, leading to infections, bleeding and anemia. It has been suggested for a long time that leukemic cells possess a growth-advantage by overproducing an inhibitor - a leukamia associated inhibitor. Such an inhibitor has been characterized in leukemic cells as well as subpopulations of normal bone marrow and blood cells, sugge

Popular Abstract in Swedish Om man betraktar ljuset fran en varm gas ser man att det har en viss färg som är beroende gasens kemiska sammansättning. Består gasen av endast ett ämne kan man genom att detaljstudera ljuset erhålla information som är specifik för just detta grundämnet. For varje grundämne finns ett mönster av spektrallinjer som bygger upp ämnets spektrum. Om spektrumen for många ämnenInvestigation of astrophysical plasmas, such as stellar atmospheres, require both knowledge of atomic structure and data. We present laboratory instruments, techniques and tools for acquisition of the data required to derive important atomic parameters such as, wavelengths, oscillator strengths and line profiles. In this thesis new atomic data for advancement of stellar atmosphere analysis are pre

To mimic the two-signal requirements for T cell activation mediated by ligands, we exposed the superantigens SEA or SEE (signal 1) to T cells incubated with HLA-DR/LFA-3 or HLA-DR/137-1-CHO transfected cells (signal 2). LFA-3 costimulation was able to induce T cell proliferation as well as IFN-gamma and IL-4 production at similar levels as in cells induced by B7-1. Analysis of the CD28RE of the IL

Evidence from wildlife and human populations indicates that conditions during early development can have marked effects on the subsequent performance of individuals and cohorts. Likewise, the effects of maternal and, more generally, parental environments can be transferred among individuals between generations. These delayed life-history effects are found consistently and suggestions have been mad

The present study had two aims: (1) to investigate potential differences in proportion of myosin heavy chain isoforms in the trapezius muscle between female cleaners with and without trapezius myalgia and healthy teachers, and (2) to elucidate if myosin heavy chain composition and surface electromyogram (EMG) during an isokinetic endurance test of shoulder flexors are significantly related. The su

The agents driving the divergence and speciation of free-living microbial populations are still largely unknown. We investigated the dinoflagellate morphospecies Scrippsiella hangoei and Peridinium aciculiferum, which abound in the Baltic Sea and in northern temperate lakes, respectively. Electron microscopy analyses showed significant interspecific differences in the external cellular morphology,

Researchers and teachers often recommend motivating exercises and use of mathematics or statistics software for the teaching of basic courses in probability and statistics. Our courses are given to large groups of engineering students at Lund Institute of Technology. We found that the mere existence of real-life data and technology in a course does not automatically increase students’ motivation o
