Estrogen and progesterone receptor analysis results were compared within and between six laboratories in Sweden using frozen breast cancer cytosol samples, and the same technique (enzyme immunoassay, Abbott Laboratories). The concordance in receptor status (positive vs. negative) was excellent (98.4% (571/580)). The discordant results were attributable to values near cut-off (n = 4) or outliers (n
Thirty-one children with mediastinal abnormalities--14 malignant lymphomas, 4 other primary malignancies, one metastatic and 12 benign lesions--were examined one or several times using CT, which proved to be effective especially for cysts (5 patients), ductus arteriosus aneurysm (2 patients), and intrathoracic liver (one patient). It also supplied important diagnostic information regarding the ext
An in-car observation method with human observers in the car was studied to establish whether observers could be trained to observe safety variables and register driver's behaviour in a correct and coherent way, and whether the drivers drove in their normal driving style, despite the presence of the observers. The study further discussed the observed variables from a safety perspective. First thre
Popular Abstract in Swedish Tarmväggen har till uppgift att både absorbera vatten och näringsämnen till kroppen, och samtidigt utgöra en barriär mot alla de bakterier, gifter och skadliga ämnen som vi får i oss. Tarmväggen innehåller också kroppens största förråd av immunologisk vävnad, dvs de celler och ämnen som utgörs kroppens försvar. I mag-tarmkanalen, ffa i tjocktarmen, finns 100 biljoner (1The gastrointestinal tract harbours a huge load of bacteria which exerts important biological functions to maintain health. In certain conditions the relation between commensal bacteria and pathogens may be set off balance, with an increase in number of pathogens and risk of bacterial translocation (BT). Disease and trauma may also render the intestinal barrier dysfunctional, inducing BT and incre
Many children with cerebral palsy have feeding difficulties. The aim of this study was to investigate if trunk and neck positioning influenced oral and pharyngeal swallow. Five children with feeding problem aged 3-10 years with cerebral palsy were examined using videofluoroscopy. All children had tetraplegia with dystonia, i.e. poor head control and poor trunk stability. All children had gross asp
In vivo photoactivation of Photosystem II was studied in the FUD39 mutant strain of the green alga Chlamydomonas reinhardtii which lacks the 23 kDa protein subunit involved in water oxidation. Dark grown cells, devoid of oxygen evolution, were illuminated at 0.8 μE m-2&#;s-1 light intensity which promotes optimal activation of oxygen evolution, or at 17 μE m-2&#;s-1, where photoactivation
The throughput performance of incremental redundancy (INR) schemes, based on short constraint length convolutional codes, is evaluated for the block-fading Gaussian collision channel. Results based on simulations and union bound computations are compared to estimates of the achievable throughput performance with random binary and Gaussian coding in the limit of large block lengths, obtained throug
Purpose: We measured concentrations of human glandular kallikrein 2 (hK2), total prostate specific antigen (tPSA), free PSA (fPSA) and percent fPSA to evaluate their relationship to total prostate gland volume, benign prostatic hyperplasia (BPH) volume, total prostate cancer (PCa) volume (CaVol) and the volume of Gleason grades 4/5 cancer (CaVolG14) in the serum of 256 patients with PCa undergoing
Deep-inelastic ep scattering data taken with the H1 detector at HERA and corresponding to an integrated luminosity of 106 pb(-1) are used to study the differential distributions of event shape variables. These include thrust, jet broadening, jet mass and the C-parameter. The four-momentum transfer Q is taken to be the relevant energy scale and ranges between 14 GeV and 200 GeV. The event shape dis
Popular Abstract in Swedish Denna avhandling bygger på en kritisk granskning av spänningen mellan etablerade och alternativa perspektiv på hållbarhetsproblematiken, med utgångspunkt i fyra olika diskurser: miljöekonomi, ekologisk ekonomi, adaptive management och bioregionalism. De fyra diskurserna representerar olika försök att i tilltagande grad utmana etablerade, modernistiska perspektiv på sociThis dissertation critically examines the tension between mainstream and counterpoint perspectives on sustainability on the basis of analyses of four approaches to this issue: environmental economics, ecological economics, adaptive management, and bioregionalism, which are presented as successive attempts to challenge mainstream, modernist perspectives on socio-ecological relationships. The differ
A photon echo experiment in Tm3+:YAG is reported that shows, for the first time to the authors’ knowledge, the time-domain equivalent of the transition from near- to far-field diffraction, including Talbot self-imaging effects. The experiment demonstrates the huge dispersion capability of photon echoes and opens the way to further exploration of space–time duality.
From a detailed elemental abundance analysis of 102 F and G dwarf starswe present abundance trends in the Galactic thin and thick disks for 14elements (O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Zn, Y, Ba, and Eu).Stellar parameters and elemental abundances (except for Y, Ba and Eu)for 66 of the 102 stars were presented in our previous studies (Bensbyet al. 2003, 2004a). The 36 stars that are new in t
STUDY DESIGN: A prospective observational study of visual analog scale (VAS) scores for pain in patients operated at one institution within the framework of a national registry. OBJECTIVE: To describe the use of recording VAS for pain intensity in patients operated on for lumbar spine problems. SUMMARY OF BACKGROUND DATA: There is no consensus regarding pain outcomes assessment in spine patients.
The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. These systems are realized by computationally complex algorithms, r
We study the function $L(t) = inf_{0 < x < 1}(x^p + t(1-x)^q)$ and related functions which arise in the theory of interpolation spaces.
During the last 30 years, the promise of neural transplantation as a therapeutic strategy for neurodegenerative disease has been slowly recognised. Across the world, clinical transplants of embryonic primary dopamine neurones have been shown to ameliorate some of the motor deficits in Parkinson s disease (PD) patients, and more recently, systematic clinical trials have been initiated for the repla
