The purpose of this study was to investigate the effect of enriched environment on motor function after experimental stroke in mice, and to determine whether time in enriched environment affects functional recovery. Earlier investigations have shown that rats placed in an enriched environment after focal ischemia, remarkably improve motor function, but similar observations in mice have not been re

Popular Abstract in Swedish Den fysiska grunden för fysiska aktionsverbThis work is a study of verbal semantics with a focus on the discussion and illustration of the role of body parts and the semantic incorporation into verbal roots of the actions that involve various body parts. Following a general discussion of the basic issues of language construction and human body actions with the image schemas of force-dynamics presented in line with the framework of cognitiv

Previously, time/temperature treatments of starch have been performed mainly on starch/water systems. In this study the same time/temperature treatments were applied to starch/water systems and to potato starch in situ. Two potato varieties (Solanum tuberosum cultivars Asterix and Bintje) were used. The effect of time/temperature treatments on gelatinisation behaviour was evaluated using different

The use of intranasal steroids for the treatment of allergic and vasomotor rhinitis has doubled during the past 5 years. The number of reported cases of nasal septum perforation has increased correspondingly. The mechanism behind this is unknown, and steroid-induced septum perforation is rarely described in the literature. In order to describe the course of events and to form an idea of the extent

Boken bygger på en doktorsavhandling från Mannheim 1998 och innehåller en intressant undersökning av den svenska kyrkliga verksamheten i Berlin (den officiella Victoriaförsamlingen) och Wien (den frivilliga Israelsmissionen) under den nationalsocialistiska tiden. Deras hjälpverksamhet för judar eller judekristna markerade distans till regimen och beskrivs som motstånd. Underrubriken lovar dock mer

Prostate specific antigen (PSA) in serum has recently been shown to occur in complex with alpha 1-antichymotrypsin and as an approximately 30 kDa. noncomplexed molecular form. We characterized PSA by 3 different assays in samples from 144 patients with benign prostatic hyperplasia (BPH) and 121 with carcinoma of the prostate. One of these noncompetitive assays measured total PSA by detecting PSA c

The purpose of this investigation was to evaluate the bone turnover by using bone metabolic markers in relation to previous fracture history and independent of bone mass. Patients and controls were recruited from a population-based study of 193 women, all living in the same city and aged 60, 70, and 80 years. The bone mineral content (BMC) was measured bilaterally in the distal forearm by single-p

Macroporous hydrogels (MHs) have been prepared by cross-linking polymerization of hydroxyethyl methacrylate (HEMA) or cross-linking co-polymerization of HEMA with dimethylacrylamide (DMAA) in semi-frozen state. The MHs are elastic and have a unique structure of large interconnected pores with pore sizes up to 100 µm and total porosity of 94–97%, as demonstrated by micro-computed tomography. The st

Adaptive estimation of the linear coefficient vector in truncated expansions is considered for the purpose of modeling noisy, recurrent signals. Two different criteria are studied for block-wise processing of the signal: the mean square error (MSE) and the least squares (LS) error. The block LMS (BLMS) algorithm, being the solution of the steepest descent strategy for minimizing the MSE, is shown

It is widely accepted that alkaline phosphatase activity (APA) is an efficient indicator of phosphate limitation in freshwater phytoplankton communities. In this study, we investigated whether the response in APA to phosphate limitation differs among the taxa in a mixed phytoplankton assemblage. We used the new enzyme-labeled fluorescence (ELF) technique, which allows microscopic detection of phos

A biofilm is a complex and diverse aggregation of microorganisms at surface comprised of among different things a protective adhesive matrix of extracellular polymeric substance. Biofilm research represents a broad range of sciences joining efforts within an interdisciplinary field of research. This thesis deals with the modeling of biofilms using the most fundamental laws of physics; the conserva

The agricultural intensification strategies represented by the Green Revolution have since the mid-1960s had a very positive impact on food-grain production in Asia. Presently, however, a post-Green Revolution phase of declining growth in output and productivity is experienced in many of the areas where intensification took place. Partly, this can be explained by a number of environmental problems

I denna skrift visas ett antal beräkningsexempel på hur fuktinnehållet i en gotländsk sandsten kan variera med varierande randvillkor. Teorin och numerisk metod för beräkningarna beskrivs i detalj.

We have investigated the C-60 monolayer on Al(l 10) with angle-dependent photoelectron spectroscopy. We find that orbital components have different angular distributions. Calculations of cross sections of the highest occupied molecular orbital components for free, oriented C-60 are found to describe the experimental data quite well. The observed band splitting is attributed to intramolecular elect

The reaction mechanism for the selective catalytic oxidation of ammonia to give nitrogen on CuO/Al2O3, Pt/Al2O3 and Pt/CuO/Al2O3 was investigated using transient experiments. Temperature-programmed desorption and reaction of adsorbed ammonia indicated the formation of NHx species at the surface, and that this species is the precursor for the formation of nitrogen and nitrogen oxides. Pt/CuO/Al2O3
