Neurite outgrowth (e.g. axonal or dendrite outgrowth) of neurons is necessary for the development and functioning of the central nervous system. It is well accepted that the differentiation of neurons and neurite outgrowth involve alterations in gene expression. Furthermore, mitochondria play a role in different aspects of neurite outgrowth. Here we show that the expression of Ndufb11, a gene enco

A critical review is presented on the state of knowledge and calculation capability for coastal overwash. Overwash and overwash deposits (washover) accompanying hurricanes and severe storms can devastate coastal communities and habitat, but in many areas these processes are essential for maintaining the integrity of barrier islands while creating new habitat. This review covers general studies of
The aim of this study was characterization of a family carrying two mutations known to cause monogenic forms of diabetes, the M626K mutation in the HNF1α gene (MODY3) and the A3243G in mtDNA. β-Cell function and insulin sensitivity were assessed with the Botnia clamp. Heteroplasmy of the A3243G mutation and variants in type 2 diabetes susceptibility genes were determined, and transcriptional activ
A prototype of the Transition Radiation Tracker (TRT) for the ATLAS experiment at the CERN LHC has been built and tested at the CERN SPS. Detailed studies of the drift-time measurements, alignment technique, hit registration efficiency, track and momentum accuracy were performed. A coordinate measurement accuracy of 150 Pin for a single TRT drift tube and momentum resolution of 0.8% for 20 GeV pio
Ethanol can be produced from lignocellulosic biomass using steam pretreatment followed by enzymatic hydrolysis and fermentation. The sugar yields, from both hemicellulose and cellulose are critical parameters for an economically-feasible ethanol production process. This study shows that a hear-theoretical glucose yield (96-104%) from acid-catalysed steam pretreated corn stover can be obtained if x

The nuclear microprobe (NMP) technique using PIXE for elemental analysis and STIM on/off axis for parallel mass density normalization has proven successful to investigate possible interactions between minerals and ectomycorrhizal (EM) mycelia that form symbiotic associations with forest trees. The ability for the EM to make elements biologically available from minerals and soil were compared in fi
A new pre-injector has been designed for the MAX-laboratory. It consists of an RF-gun and a magnetic energy filter. The newly designed RF-gun geometry will be operated at 3 GHz in the thermionic mode using a BaO cathode. The pre-injector will provide a 2.3 MeV electron beam in 3 ps micro pulses to a new injector system currently under construction. (C) 2002 Elsevier Science B.V. All rights reserve
Primary systemic vasculitis is associated with a high mortality if left untreated and it is essential to make the diagnosis before permanent organ damage has occurred. In this thesis the diagnostic and prognostic significance of anti-neutrophil cytoplasmic antibodies (ANCA) in systemic vasculitis is investigated. The clinical significance of a capture enzyme-linked immunosorbent assay (ELISA) bas
We have shown in a previous study that leukotriene D-4 (LTD4) signalling increases cell survival and proliferation in intestinal epithelial cells [ohd, Wikstrom and Sjolander (2000) Gastroenterology 119, 1007-1018]. This is highly interesting since inflammatory conditions of the bowel are associated with an increased risk of developing colon cancer. The enzyme cyclooxygenase 2 (COX-2) is important
Scatter correction in SPECT is important for improving image quality, boundary detection and the quantification of activity in different regions. This paper presents a comparison of four scatter correction methods, three using more than one energy window and one convolution-subtraction correction method using spatial variant scatter line-spread functions. METHODS: The comparison is based on Monte
Aim: The study investigated clinical and social changes during an 18-month follow-up period in a group (n = 76) of schizophrenic outpatients admitted to a newly implemented outpatient psychosis team. Changes related to level of contact with the psychosis team were also examined as well as aspects of the content of the treatment interventions and work situation from a staff perspective. Methods: St
To increase our knowledge about mating-system evolution, we need to understand the relationship between specific floral traits and mating system. Species of Collinsia (Plantaginaceae) vary extensively in mating system; this variation is associated with variation in floral morphology and development and with the timing of self-pollination. Counterintuitively, large-flowered, more outcrossing specie
In the light of a brief review of the theories of power — in which the definitions of power are asked when, where and how is power executed? — the article defines power as the ability of an individual or a collective actor to cause, effect and prevent action in others and to achieve the desired results. The article then concentrates on a kind of power which is called acculturation. This appears in

Maternally Inherited Diabetes and Deafness (MIDD) and Maturity Onset Diabetes of the Young (MODY) are monogenic forms, whereas Latent Autoimmune Diabetes in Adults (LADA) is thought to be a polygenic subtype similar to T1D.

Background. Exercise is an important part of many women's lives. Women are often advised to refrain from physical exercise during pregnancy. The reason given is mainly safety, i.e. fear of maternal hyperthermia, which is known to be related to neural tube defects. However, exercise during pregnancy has not been shown to be related to hyperthermia. Objective. To study temperature and oxygen satura
The main stimulus for insulin secretion is elevated blood glucose levels. In this thesis the aim was to study less well-known systems involved in the complex regulation of glucose-stimulated insulin release, emphasizing the role of the lysosomal/vacuolar system and the associated glycogenolytic acid alpha-glucoside hydrolases, but also the HO-CO and NOS-NO systems. We performed studies both in hea
In this paper we study harmonic morphisms emptyv :U sub CopfP m rarrN 2 from open subsets of complex projective spaces to Riemann surfaces. We construct many new examples of such maps which are not holomorphic with respect to the standard Kähler structure on CopfP m.
