Current understanding of microglial involvement in disease is influenced by the observation that recruited bone marrow (BM)-derived cells contribute to reactive microgliosis in BM-chimeric mice. In contrast, a similar phenomenon has not been reported for BM-chimeric rats. We investigated the recruitment and microglial transformation of BM-derived cells in radiation BM-chimeric mice and rats after
Summary Aquaporins facilitate water transport over cellular membranes and are therefore believed to play an important role in water homeostasis. In higher plants aquaporin-like proteins, also called major intrinsic proteins (MIPs), are divided into 5 subfamilies. We have previously shown that MIP transcription in Arabidopsis thaliana generally is down-regulated in leaves upon drought stress, apart
Background Microarray technology has become popular for gene expression profiling, and many analysis tools have been developed for data interpretation. Most of these tools require complete data, but measurement values are often missing A way to overcome the problem of incomplete data is to impute the missing data before analysis. Many imputation methods have been suggested, some naïve and other mo
Critical review of Lena Israel's doctoral thesis.
Medieval round churches are often seen as riddles in need of special explanation. Deviant architecture has been explained by three major theories – fortification, multi-functionality and symbolic copying. However, I claim that the round churches were normal except for their elite context and extraordinary plan. I then argue, that the elite consciously choose a “conspicuous architecture”, to use a
Under den senaste tioårsperioden har ofta förhållandena i grundskolan varit på tapeten. Ett tag var alla skoldebattörer helt enkelt tvungna att tala om "grundskolans kris". I denna debatts kölvatten kom en rad välmenande, bakåtsträvande, framåtsyftande reformförslag. Tvång, mindre klasser, normer, nivågruppering, basfärdigheter, ordning och reda och allt vad det nu var. Stundtals kom också autenti
The mean effective gain (MEG) for Rice distributed signals impinging at the terminal receiver antenna is presented. Numerical results are presented for three different angular probability distributions of impinging waves. Finally, it is shown that contrary to the Rayleigh channels in Ricean channels there is no inclination angle at which the MEG of the half-wave dipole antenna remains constant reg
The present paper concerns a performance-based fire safety analysis and design of a high-rise building. The resulting fire safety recommendations are compared with those specified by acceptable solutions in terms of the earlier prescriptive building code. The respective risk to life resulting from the analysis is compared and discussed. The benefit and need of using a risk based verification metho
Background: Several studies analyze how surgical delay affects patients with hip fracture. The aim of this study was to identify the causes of surgical delay and demographic characteristics in patients with hip fracture who had delays longer than 24 hours from admission to hospital. Methods: Quantitative retrospective register study of 484 patients was consecutively included during the period Nove
