Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,

This review summarizes and discusses the use of central health registers in studies of causes of congenital malformations. The review is illustrated using data from the Swedish Medical Birth Register with adjacent registers and gives examples of different methods to identify environmental exposures. The review stresses the usefulness of this approach but also the inherent problems of which the res

Reduction of the model platinum(IV) complexes cis-[PtCl4(NH3)(2)] (1), trans-[PtCl4(NH3)(2)] (2). trans-[PtCl2(en)(2)](2+) (3), trans-[PtBr2(NH3)(4)](2+) (4), [PtCl6](2-) (5), and [PtBr6](2-) (6) with L-ascorbic acid (H(2)Asc) in 1.0 M aqueous medium at 25 degreesC in the region 1.75 less than or equal to pH less than or equal to 7.20 has been investigated using stopped-flow spectrophotometry. The

The metallation of tetrapyrroles is believed to proceed via a sitting-atop (SAT) complex, in which some of the pyrrole nitrogen atoms are protonated and the metal ion resides above the ring plane. No crystal structure of such a complex has been presented, but NMR and EXAFS (extended X-ray absorption fine structure) data has been reported for Cu2+ in acetonitrile, which have been interpreted as the

Four wastewater samples of different treatment qualities; untreated, alarm, alert and normal, from a Swedish chen-ti-thermo-mechanical pulp mill and pure water were investigated using an amperometric bioelectronic tongue in a batch cell. The aim was to explore enzymatically modified screen-printed amperometric sensors for the discrimination of wastewater quality and to counteract the inherent drif

In this paper, we consider fundamental limitations for DOA estimation with arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical vector modes and their associated equivalent circuits and Q factor approximations are employed as a general framework for the analysis. The classical broadband matching theory by Fano is extended to a general multiport S-parameter model of the

We show the implications of the commonly observed age-related decline in aboveground productivity of forests, and hence forest age structure, on the carbon dynamics of European forests in response to historical changes in environmental conditions. Size-dependent carbon allocation in trees to counteract increasing hydraulic resistance with, tree height has been hypothesized to be responsible for th

The paper presents three optimization models for designing robust two-layer networks carrying elastic traffic. The formulations correspond to different restoration mechanisms against failures. An original iterative algorithms to solve the models is given and illustrated with numerical examples. The models can be applied for designing NGI IP over DWDM core networks.

Background: Different screening procedures are becoming an important part of health care. information about screening and its consequences can be difficult to both impart and understand. This study examined women's theoretical acceptance of a new screening procedure, before its introduction. Methods: A group of women (n = 823), who had made an informed choice about the form of foetal diagnosis the

Objectives. The aims of the present study were to analyze patient- and management-related predictors for outcome after open (OR) and endovascular repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA). Design. Retrospective study. Materials. The in-hospital registry of Malmo University Hospital identified 162 patients operated on due to rAAA between 2000 and 2004. Methods. Patient- and managem

When analysing new types of sewage systems, knowledge is needed on the composition of the different wastewater fractions. The computer model URWARE, developed from the model ORWARE, is intended to analyse and compare different wastewater system structures, e.g. to compare wastewater systems where urine and/or faeces are source separated with conventional wastewater systems, where the different was

The pseudoscalar meson eta(b) has been searched for in two-photon interactions at LEP II. The data sample corresponds to a total integrated luminosity of 617 pb(-1) at centre-of-mass energies ranging from 161 to 209 GeV. Upper limits at a confidence level of 95% on the product Gamma(gamma gamma) (eta(b)) x BR(eta(b)) are 190, 470 and 660 eV/c(2) for the eta(b) decaying into 4, 6 and 8 charged part

Primers for amplification and sequencing of partial glyceraldehyde-3-phosphate dehydrogenase (gpd) gene were designed for lichenized fungi. The 5' gpd primer is most probably fungal specific, since a BLAST search in GenBank found identical sequences only from ascomycetous taxa, whereas the 3' gpd primer was more universal. Utility of the gpd primers and previously designed beta-tubulin primers was
