The ability of electrical field stimulation in releasing transmitter from isolated blood vessels in vitro, during recordings of constrictor or dilator responses, is dependent upon an appropriate choice of stimulation parameters which avoid concomitant change in tone due to a direct effect on the vascular smooth muscle membrane. In many species, including man, small arteries such as pial arteries f

Measurements of the stopping forces for C-14, N-14 and O-16 ions in Ge and Au, for N-14 and F-19 ions in Ag, as well as for F-19 ions in Au have been made, respectively. A novel technique, reported recently, using PIN diodes coated directly with the stopping medium in a polka dot pattern was used. This provided a set of precise, self-consistent measurements on the same stopping medium. Results sho

All hematopoietic cells originate from hematopoietic stem cells (HSC) residing in the BM. The process of differentiation, through which HSCs generate progenitors and subsequently mature blood cells has been extensively studied but many of the regulatory mechanisms involved remains elusive. The classical model for hematopoiesis has been established based on the identification of common myeloid prec

An exploratory study on the prosodic signaling of ‘confirmation’ in Swedish is presented. Pairs of subjects read short dialogs, constructed around selected target words, in a conversational style. The target utterances were produced with a rising-falling intonation, lacking any typical ‘focal accent’ (FA). Qualitative observations and acoustic measurements reveal that the signaling of the word acc

The aim of this thesis is to investigate the potential of applying a community-based intervention, implemented in the Swedish city of Trelleborg 1999-2002, to reduce adolescent alcohol use. In order to do so, we had four specific aims. First, we studied the processes, both in terms of action and institu-tionalization, within the intervention. This would improve our understanding of the quantitativ

Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. Three public transport systems are focused, service route traffic, trunk route traffic and special transport service, which demand different capa

Measurements of nuclear properties of some neutron-rich asymmetric fission isotopes at an ISOL laboratory present a severe problem when a plasma ion source is used as the primary ion-source. The problem is associated with intense multi-charged symmetric fission contaminants that cannot be mass-separated from asymmetric fission products. In this work we demonstrate how this problem can be overcome

Fault detection and isolation (FDI) are important steps in the monitoring and supervision of industrial processes. Biological wastewater treatment (WWT) plants are difficult to model, and hence to monitor, because of the complexity of the biological reactions and because plant influent and disturbances are highly variable and/or unmeasured. Multivariate statistical models have been developed for a

This is a survey of acute lymphoblastic leukemia (ALL) in Swedish children from 1968 to 2001. The survival has increased from a few per cent to more than 80 per cent of children with ALL in these national complete patient materials. Changes in diagnosis and treatment are discussed as well as the importance of supportive care. The favorable results can almost certainly be ascribed to continuous coo

Model systems have shown that adenoviral vector mediated transient gene expression can potentially be applied for the treatment of brain tumours, neurodegenerative diseases and brain injuries. Most studies utilized adenovirus serotype 5 (Ad5) based vectors, which as adhesion molecules require the coxsackie adenovirus receptor (CAR) as a critical determinant for cellular infection. In this report,

Experiments were conducted to study the energy efficiency of the impulse unit in the pilot-scale research paper machine at the Swedish Pulp and Paper Research Institute (STFI) In Stockholm, Sweden. The paper produced was made of kraft softwood pulp with basis weights of 60-120 g/m(2). The roll surface temperature ranged from ambient temperature to 350 degreesC and the press loads were between 400-

Objective. Increasing survival of extremely low birth weight (ELBW; birth weight < 1000 g) infants raises a concern regarding the risks of adverse long-term outcome such as cognitive dysfunction. Few studies have reported long-term follow-up of representative regional cohorts. The objective of this study was to assess the 5-year outcome of a prospectively followed national ELBW infant cohort. Meth

Apolipoprotein ( apo) M is a novel apolipoprotein belonging to the lipocalin protein superfamily, i.e. proteins binding small lipophilic compounds. Like other apolipoproteins, it is expressed in hepatocytes and secreted into plasma where it associates with high-density lipoprotein particles. In addition, apoM is expressed at high levels in the kidney tubule cells. In this study, we show that the m
