Functional outcome in rats transferred to an enriched environment 15 days after focal brain ischemia

BACKGROUND AND PURPOSE: The aim was to determine whether a delayed transfer to an enriched environment improves outcome after focal brain ischemia. METHODS: Performance on a rotating pole, prehensile traction, limb placement, and postural reflexes were tested in 15 spontaneously hypertensive rats housed in standard laboratory cages for 2 weeks after middle cerebral artery ligation. Seven of the 15

Occurrence of nematodes, tardigrades and rotifers on ice-free areas in East Antarctica

Nematodes, rotifers and tardigrades were collected on three nunataks (mountain peaks penetrating the ice sheet) in Vestfjella, on six nunataks; in Heimefrontfjella and on the Schirmacher Oasis in East Antarctica in the austral summers of 1996/97 and 2001/02. Most samples were taken on the nunatak Basen in Vestfjella where the Swedish station Wasa is located. The microfauna was patchily distributed

Svensk evangelisk väckelse på Bornholm

I denna uppsats behandlas andliga förbindelser mellan Sverige och Bornholm under 1800- och 1900-talet. Den rosenianska väckelsen kom att i hög grad ge det andliga livet på Bornholm dess särprägel. Liksom den rosenianska rörelsen i Sverige kanaliserades dels i Evangeliska Fosterlandsstiftelsen (EFS), dels i Bibeltrogna Vänner (BV), har motsvarande rörelse på Bornholm förgrenats i Luthersk Missionsf

Characteristic state plasticity for granular materials Part II: Model calibration and results

A non-associated plasticity theory for granular materials has been developed in Part 1 based on the concept of a characteristic stress state of vanishing incremental dilation. The model is fully three-dimensional and is defined by six material parameters: two for elastic stiffness, one for plastic stiffness, two for the shapes of yield and plastic potential surfaces and one for the dilation at fai

Space-Time Prediction of Ocean Winds

The topic of this thesis is inspired by an experiment in which a vessel, laying a submarine cable, was provided with forecasts overlaid with satellite observations of significant wave height. During the operation, the vessel was close to an adverse weather area and the personnel on board could confirm that the forecast was not as close to the "ground truth" as the satellite observation was.

Boron neutron capture therapy for glioblastoma multiforme : Clinical studies in Sweden

A boron neutron capture therapy (BNCT) facility has been constructed at Studsvik, Sweden. It includes two filter/moderator configurations. One of the resulting neutron beams has been optimized for clinical irradiations with a filter/moderator system that allows easy variation of the neutron spectrum from the thermal to the epithermal energy range. The other beam has been designed to produce a larg

Cdc42 is involved in PKCepsilon- and delta-induced neurite outgrowth and stress fibre dismantling.

We have shown that protein kinase C (PKC)epsilon, independently of the catalytic domain, induces outgrowth of cellular processes via its regulatory domain in both neural cells and fibroblasts. This was accompanied by stress fibre loss. Here, we have examined the role of the small GTPases, Rac1, and Cdc42, in these PKC-mediated morphological and cytoskeletal changes. Both constitutively active and

Optimizing Presence–Absence Surveys For Detecting Population Trends

Presence–absence surveys are a commonly used method for monitoring broad-scale changes in wildlife distributions. However, the lack of power of these surveys for detecting population trends is problematic for their application in wildlife management. Options for improving power include increasing the sampling effort or arbitrarily relaxing the type I error rate. We present an alternative, whereby

Effect of glibenclamide on membrane response to metabolic inhibition in smooth muscle of rat portal vein

Vascular smooth muscle tone is dependent on oxidative metabolism, a phenomenon of potential importance for the metabolic regulation of blood flow to tissues. The response of the rat portal vein to inhibition of cell respiration by cyanide (0.1-1 mM) is a reduction of its spontaneous myogenic activity. The trains of action potentials triggering phasic contractions are reduced in duration, while the

Differential activation by Ca2+, ATP and caffeine of cardiac and skeletal muscle ryanodine receptors after block by Mg2+

The block of rabbit skeletal ryanodine receptors (RyR1) and dog heart RyR2 by cytosolic [Mg2+], and its reversal by agonists Ca2+, ATP and caffeine was studied in planar bilayers. Mg2+ effects were tested at submaximal activating [Ca2+] (5 microM). Approximately one third of the RyR1s had low open probability ("LA channels") in the absence of Mg2+. All other RyR1s displayed higher activity ("HA ch

An integrated analysis of ergonomics and time consumption in Swedish "craft-type' car disassembly

Car disassembly is at the edge of extensive rationalisations due to increased legislative demands for recycling. This study focused on (1) assessing Current mechanical exposures (physical work loads) for comparison with future rationalised systems, with particular emphasis on time aspects, (2) analysing disassembly work in terms of time consumption and exposures in constituent tasks as defined by
