Popular Abstract in Swedish Kroppens immunförsvar består av röda och vita blodceller som alla härstammar från blodbildande stamceller i benmärgen. Stamcellerna har den unika egenskapen att kunna producera alla typer av blodceller och upprätthålla produktionen hela livet ut. I princip all blodbildning (hematopoes) sker i benmärgen, förutom för T celler. Dessa är vita blodceller som produceras i thyhe hematopoietic development is a highly dynamic but tightly regulated process. The flexibility to produce blood cells through more than one route will allow the blood system to respond rapidly in stress situations such as infections. On the other hand, regulation of the blood system is required to prevent blood cells from uncontrolled proliferation that could result in leukemia or bone marrow fai

To investigate the genotype and phenotype in families with adenosine triphosphate-binding cassette, sub-family A, member 4 (ABCA4)-associated retinal degeneration.

Developing new and useful methods in asymmetric catalysis is of continuous importance. A current challenge is to address the imperatives of green chemistry, such that processes maximize resource-efficiency and minimize the generation of waste. To this end, this article discloses the potential of alpha-amino acids in the development of entropy-controlled and enantiodivergent Lewis acid catalysis. I

Cigarette smoke exposure increases the risk of stroke. However, the underlying molecular mechanisms are poorly understood. Endothelin system plays key roles in the pathogenesis of stroke. The present study was designed to examine if lipid-soluble (dimethyl sulfoxide-soluble) cigarette smoke particles (DSP) induces upregulation of contractile endothelin type B (ETB) receptors in rat cerebral arteri

We have studied the (110) GaAs surface of a structure containing ortho twins by cross-sectional scanning tunnelling microscopy and we have compared the experimental results with ab initio density functional theory calculations and STM simulations. Both experimentally and theoretically we find that the surface of different twin crystallites are significantly displaced with respect to each other, pa

Objectives. Objective signs of autonomic dysfunction (AD) have been reported in patients with primary SS (pSS) while the presence of associated symptoms has not been systematically studied. Therefore, the aims of this study were (i) to assess the presence and severity of various AD symptoms in pSS patients and (ii) to relate AD symptoms to other clinical features of pSS. Methods. Thirty-eight pSS

Abstract in Undetermined Heimann, M., Nordqvist, E., Rudner, M., Johansson, M. & Lindgren M. (2013). Associative learning measured with ERP predicts deferred imitation using a strict observation only design in 14 to15 month old children. Scandinavian Journal of Psychology 54, 33-40. Deferred imitation (DI) is an established procedure for behavioral measurement of early declarative-like memorie

A highly efficient anode for glucose biofuel cells has been developed by a combination of pyranose dehydrogenase from Agaricus meleagris (AmPDH) and cellobiose dehydrogenase from Myriococcum thermophilum (MtCDH). These two enzymes differ in how they oxidize glucose. AmPDH oxidizes glucose at the C(2) and C(3) carbon, whereas MtCDH at the C(1) carbon. Both enzymes oxidize efficiently a number of ot

Sepsis and invasive bacterial infection is a major cause of human disease and death worldwide. Streptococcus pyogenes is one of the major pathogens responsible for bacterial infections, which range from mild to severe and life threatening conditions. S. pyogenes contains a cell wall anchored M protein, which is an important virulence factor that can interact with many cells of the immune system. O

Popular Abstract in Swedish Introduktion Aggressivt antisocialt beteende utgör en stor utmaning för dagens samhälle, och undersökningar av vad som ligger bakom ett återkommande sådant beteende behövs för utvecklingen av våldspreventiva insatser. Syften & Metod Syftet med avhandlingen var att identifiera faktorer som samvarierar med återkommande aggressivt antisocialt beteende. De specifika måIntroduction Aggressive antisocial behavior is a major challenge to society, and studies on the determinants of its persistence are essential to the development of strategies to prevent violence. Aims & Methods The overall aim of the thesis was to establish covariates of persistent aggressive antisocial behavior in a population-based cohort and in clinically evaluated, prospectively followed,

Background: Reliable, valid, and easy-to-administer instruments to identify possible caseness and to provide proxies for clinical diagnoses are needed in epidemiological research on child and adolescent mental health. The aim of this study is to provide further validity data for a parent telephone interview focused on Autism - Tics, Attention-deficit/hyperactivity disorder (AD/HD), and other Comor

The expansion of wind power in Sweden has brought increasing conflicts between the wind power industry and the interests of the military forces. This paper analyses the reasons for these perceived conflicts and suggests solutions for mitigating at least some of the problems. The analysis is based on literature studies, several semistructured interviews and workshops with stakeholders in Sweden, De

The molecular mechanisms by which the black eumelanin biopolymers exert their photoprotective action on human skin and eyes are still poorly understood, owing to critical insolubility and structural heterogeneity issues hindering direct investigation of excitation and emission behavior. Recently, we set up strategies to obtain water-soluble 5,6-dihydroxyindole (DHI)-based polymers as useful models

We have studied the growth of doped InAsyP1-y (InAsP) NWs and InAsP-InP core-shell NWs. Using hydrogen chloride (HCl) we were able to prevent radial growth on the InAsP NWs. Undoped and H2S-doped InAsP NWs had almost pure wurtzite crystal structure, while DEZn-doped NWs showed wurtzite periodically separated by short sections of pure zincblende with rotational twins. Electrical measurements confir

It has been a common practice both in Sweden and worldwide to enclose nuclear reactors with prestressed concrete structures. The prestress level decreases with time from its initial value due to various degradation mechanisms. To ensure that the prestress level is sufficient the tendon force is measured at regular in-service inspections. The intention with this paper is to present a reliability-ba

The analysis of annual extremes of hydrological and meteorological variables is frequently complicated by the presence of gaps in record, and when records are not only fragmented but also short, it is necessary to utilize to the full the information contained in them. One method is to abstract for statistical analysis all extreme events whose peaks exceed a pre-selected threshold value, but the th
