Linking agricultural policies to population trends of Swedish farmland birds in different agricultural regions
1. The widespread declines of farmland birds have generally been linked to agricultural intensification. We tested the hypotheses that (i) changes in agricultural policy, through its effects on agricultural intensification and (ii) regional differences in agricultural intensification affect temporal and spatial population trends of farmland birds in Sweden. 2. We analysed regional bird populat
Ethnic background, labor market attachment and severe morbidity: Hospitalization among immigrants in Sweden 1990-2001
This article examines differences in health among immigrants in Sweden from 1990 to 2001. Controlling for demographic characteristics, most immigrant groups display higher rates of hospitalisation than native Swedes, but when socio-economic factors are introduced, only Nordic immigrants display rates that are significantly higher than for Swedish-born individuals. High rates of hospitalisation amo

Somatic deletions in hereditary breast cancers implicate 13q21 as a putative novel breast cancer susceptibility locus
A significant proportion of familial breast cancers cannot be explained by mutations in the BRCA1 or BRCA2 genes. We applied a strategy to identify predisposition loci for breast cancer by using mathematical models to identify early somatic genetic deletions in tumor tissues followed by targeted linkage analysis. Comparative genomic hybridization was used to study 61 breast tumors from 37 breast c
Physiological determinants of the variation in left ventricular mass from early adolescence to late adulthood in healthy subjects.
Background: The physiological determinants of left ventricular mass (LVM) measured by cardiac magnetic resonance (CMR) imaging are not well defined as prior investigators have studied either adults or adolescents in isolation or have not strictly excluded hypertension or accounted for the effects of exercise habits, haemodynamic, demographic, or body shape characteristics. Methods: A total of 102
Changes in spectral shape of tissue optical properties in conjunction with laser-induced thermotherapy
We measured the optical properties on samples of rat liver tissue before and after laser-induced thermotherapy performed in vivo with Nd:YAG laser irradiation. This made it possible to monitor not only the influence of coagulation on the scattering properties but also the influence of damages to vessels and heat-induced damage to blood on the absorption properties. An experimental integrating-sphe
A phylogenomic study of endosymbiotic bacteria
Endosymbiotic bacteria of aphids, Buchnera aphidicola, and tsetse flies, Wigglesworthia glossinidia, are descendents of free-living gamma-Proteobacteria. The acceleration of sequence evolution in the endosymbiont genomes is here estimated from a phylogenomic analysis of the gamma-Proteobacteria. The tree topologies associated with the most highly conserved genes suggest that the endosymbionts form
Lipase mediated simultaneous esterification and epoxidation of oleic acid for the production of alkylepoxystearates
Epoxy alkylstearates were synthesized by lipase catalysed esterification and perhydrolysis followed by epoxidation of oleic acid in a one-pot process. Immobilized Candida antarctica lipase (Novozym 435) was used as the catalyst. The esterification reaction occurred relatively quickly and was followed by epoxidation of the alkyl ester and the remaining fatty acid. Higher degree of esterification wa
Theoretical Study of Photodissociation of Low Lying Excited States of Hydrogen Peroxide
In order to explain recent photofragmentation experiments of hydrogen peroxide, the vertical excitation energies, potential-energy curves and surfaces, harmonic vibrational frequencies, and transition moments for a number of low lying excited states were calculated. The accessibility of different photodissociation channels for different excitation wavelengths was discussed, on the basis of the cal
Identification of a strongly activating human anti-CD40 antibody that suppresses HIV-1 infection
We characterized the functional properties of a novel set of human anti-CD40 monoclonal antibodies originating from a human phage display library and identified an antibody that strongly activates cells via the CD40 receptor for potential use in HIV therapy. The anti-CD40 antibodies were converted from a single chain antibody fragment format (scFv) to an IgG format and produced in HEK293 cells, an
On the spectral efficiency of a sphere
In many cases it is desired to have both high capacity and small antennas in wireless communication systems. Unfortunately, the antenna performance deteriorate when the antennas get electrically small. In this paper fundamental limitations from antenna theory and broadband matching are used to analyze the spectral efficiency of an arbitrary antenna inserted inside a sphere.

Propofol infusion rate does not affect local pain on injection.
BACKGROUND: Local pain at the site of an i.v. injection of propofol is a well-known problem, particularly in infants. This randomised investigator-blinded crossover study was designed to assess the effect of the i.v. bolus infusion rate on propofol-induced pain at the site of injection. METHODS: Thirty unpremedicated patients scheduled for ear-nose-throat or plastic surgery at Malmö University Hos

Proton MR spectroscopy in clinical routine
In vivo magnetic resonance spectroscopy (MRS) addresses metabolic pathways and their steady states in different tissue types. The brain has by tradition, and due to technical limitations in other organs, been one of the tissues most studied by MRS, and both 1H- and 31P-MRS have been used. Although 31P-MRS is outstanding for the evaluation of sources of metabolic energy in the brain, 1H-MRS has bec
Acculturation, self-efficacy and social support among Chinese immigrants in Northern Ireland
An opportunity sample of 108 Chinese participants (n(male) = 51 and n(female) = 57; M-age = 29.34) was compared to a second opportunity sample of 98 Northern Irish participants (n(male) = 45 and n(female) = 53; M-age = 23.67) on levels of acculturation, self-efficacy and social support. The administered questionnaire contained three scales to measure the aforementioned constructs. The first was th

Summary of the situation for women in physics in Sweden
This paper describes a general picture of efforts to provide women with equal opportunity both on a national political level, and within academia. A report of recent activities within the newly formed National Division for Women in Physics within the Swedish Physical Society is also given
The influence of wavelength and probe configuration on findings of a skin vasoconstriction test when using laser Doppler perfusion devices.
The aim of this study was to establish the degree to which a standardized test based on laser Doppler blood flow measurement is dependent on the particular equipment set-up being used. For this purpose, we examined finger skin blood flow with laser Doppler instruments in 20 healthy subjects. In laser Doppler perfusion monitoring (LDPM), we used a custom-made probe with two detecting fibers placed
