Primary headaches (e.g. migraine and cluster headache), the symptoms of which is associated with cranial vascular activity, is likely to be dependent on a primary central nervous system dysfunction. To further our understanding of the mechanisms behind primary headaches, we investigated the central projections of sensory nerves from three cranial vessels by tract-tracing techniques. In papers I-I

Background: Airway inflammation is associated with an increased expression and release of inflammatory reactants that regulate processes of cell migration, activation and degranulation. The purpose of this study was to quantify bronchial lavage (BAL) fluid and serum levels of chemokine (IL-8), secretory leukocyte protease inhibitor (SLPI), soluble intracellular adhesion molecules-1 (sICAM-1) and s

A supramolecular complex composed of Ru(II) tris-bipyridine, tyrosine, and dipicolylamine was synthesized and characterized. This complex was attached to TiO2 nanocrystalline films via ester groups at the Ru(II) chromophore, and photoinduced multistep electron transfer was investigated by laser flash photolysis and electron paramagnetic resonance techniques. Following ultrafast electron injection

In 1999, seven dark-bellied brent geese Branta bemicla bemicla were followed during spring migration from western Europe to Arctic Russia using satellite telemetry. For six of the birds we were also able to monitor their summer stay at the Taymyr Peninsula, and for five birds part of their autumn migration was recorded. In this article, we report on site use during summer and spring/autumn migrati

De senaste åren har bjudit på en veritabel revolution beträffande tekniken i fordon. Utvecklingen av kraftfulla, billiga och pålitliga mikroprocessorer har öppnat dörren för avancerad datorbaserad styrning av en mångfald fordonsfunktioner. Mycket av den nya tekniken syns inte på utsidan av fordonen, men innebär väsentliga förbättringar för miljö, säkerhet, ekonomi och bekvämlighet.

Texas has rapidly emerged as one of the leading wind power markets in the United States. This development can be largely traced to a well-designed and carefully implemented renewables portfolio standard (RPS). The RPS is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation. Though replacing existing renewable energy policies

We introduce a novel soft antenna selection approach for multiple antenna systems through a joint design of both RF (radio frequency) and baseband signal processing. When only a limited number of frequency converters are available, conventional antenna selection schemes show severe performance degradation in most fading channels. To alleviate those degradations, we propose to adopt a transformatio

Background It is only recently that comorbidity in ADHD has come to the forefront as one of the most important aspects of the disorder. It is agreed that, often, these problems are at least as important as ADHD in contributing to the longer term outcome in the individual child. Objective To provide the reader with basic information about clinics and treatment of comorbidity in ADHD. Method Revie

Kinetics of interstitial oxygen loss and oxygen-related thermal double donor (TDD) generation upon heat treatments of Ge:O crystals at 350 degrees C have been studied. The TDD concentration (N-TDD) was derived from Hall effect measurements in the temperature range 77-400 K. The bistability of the first TDD species was taken into account. The interstitial oxygen concentration ([O-i]) in the crystal

OBJECTIVES: Long-term, low-dose macrolide therapy is effective in the treatment of chronic rhinosinusitis. It is believed that macrolide antibiotics produce this benefit through an anti-inflammatory effect. In this study, the effect of clarithromycin treatment on the expression of transforming growth factor (TGF)-beta and the key pro-inflammatory nuclear transcription factor, NF-kappa B, was exami

The personalities and qualities of nursing personnel are considered to be of great importance for their interactions and nursing relationships with patients and may also influence work satisfaction. The aim of the study was to explore the extent to which different personal qualities and personality factors, with a possible effect on motivation, professional conduct and coping with stress and anxie

Popular AbstractI denna studie står de brottslingar som befolkar amerikanska polis- och deckarserier i fokus. Två huvudgrupper urskiljs: De som begår brott på grund av de omständigheter de befinner sig i och de där brottsligheten framställs som en inre egenskap. I de olika avsnitten skildras hur de senare fördöms och exkluderas från den samhälleliga gemenskapen medan de förra förlåts för sin brottIn this study, American police- and detective-series are analysed. I focus on the portrayal of the criminals, especially the moral aspect. The series can be regarded as moral tales. The morality is embedded in the characters that populate the different episodes. There are two major categories of criminals in the series; the essentialized criminals and the ones that commit crimes due to circumstanc

The concept of perceptual defensiveness is related to subliminal perception and preconscious processing. Meta-analyses of earlier experiments, 6 in the United States and Holland and 10 in Iceland, on the Defense Mechanism Test (DMT)-ESP relationship had shown significantly higher ESP scoring by less defensive participants. In the present experiment, conducted in Freiburg, Germany, 50 participants

Experiments were conducted under growth chamber conditions in order to investigate the importance of the background light quality for the effect of UVB (280–320 nm) radiation on plants. Three week-old sugar beet (Beta vulgaris L.) plants were irradiated for three weeks with enhanced levels of UVB radiation with the following background light conditions: white light (WL) (350–700 nm), WL+UVA (suppl
