Simple roles for photoreception are likely to have preceded more demanding ones such as vision. The driving force behind this evolution is the improvement and elaboration of animal behaviors using photoreceptor input. Because the basic role for all senses aimed at the external world is to guide behavior, we argue here that understanding this "behavioral drive" is essential for unraveling the evolu
For memory retrieval, pattern completion is a crucial process that restores memories from partial or degraded cues. Neurocognitive aging models suggest that the aged memory system is biased toward pattern completion, resulting in a behavioral preference for retrieval over encoding of memories. Here, we built on our previously developed behavioral recognition memory paradigm—the Memory Image Comple
Rapid and reliable observations of soil electrical conductivity are essential in order to maintain sustainable irrigated agriculture. Direct measurement of the electrical conductivity of saturated soil paste (ECe), however, is tedious andtime consuming. Therefore, there are needs to find efficient indirect methods to predict the soil salinity from other readily available observations. In this pape
The anaerobic bacterium Finegoldia magna is part of the human commensal microbiota, but is also an important opportunistic pathogen. This bacterium expresses a subtilisin-like serine-proteinase, SufA, which partially degrade the antibacterial chemokine MIG/CXCL9. Here, we show that MIG/CXCL9 is produced by human keratinocytes in response to inflammatory stimuli. In contrast to the virulent human p
The observation that neural grafts can induce dyskinesias has severely hindered the development of a transplantation therapy for Parkinson's disease (PD). We addressed the hypothesis that inflammatory responses within and around an intrastriatal graft containing dopamine neurons can trigger dyskinetic behaviors. We subjected rats to unilateral nigrostriatal lesions with 6-hydroxydopamine (6-OHDA)
This PhD thesis is made up of five independent studies and a comprehensive synthesis. The first three studies are published 2001 in the book Vem behöver en by? Kyrkheddinge, struktur och strategi under tusen år (pp. 1-95) (Who needs a village? Kyrkheddinge, Structure and Strategy During a Thousand Years). The remaining two parts and the synthesis are published in the volume Den medeltida byns soci
Aims: Respondent-driven sampling is a research technique, new to the Scandinavian setting, used in hard-to-reach populations, such as subjects at risk for HIV, including drug users. This study aimed to evaluate the use of respondent-driven sampling originating from syringe exchange clients, as a method to identify 'hidden' drug users without treatment or social service contact. Methods: Nine heroi
Wind power is seen by many observers as an important part of the transition to a sustainable energy system, since it does not contribute to the environmental problems connected with dominating energy forms such as fossil fuel, nuclear power and large-scale hydro power. At the same time wind power has some characteristics that makes it a special challenge for land use planning. In Sweden, where win
Purpose: Sick leave and unemployment are highly prevalent among people with affective disorders. Their depression severity is disabling and inversely related to having employment. No evidence-based vocational rehabilitation exists for this target group. Knowledge is therefore needed to understand the psychosocial factors that affect depression severity in order to develop new rehabilitation interv
The present thesis explores Japanese imperative constructions from a general linguistic perspective, as well as examining the imperative as a cross-linguistic object of study. On the definitional side, a terminological apparatus for the description and analysis of imperatives and directives is presented. It includes the proposal that the range of conventional directive strategies in a language be
To meet the needs of an increasing, heterogeneous, ageing population it is imperative to understand links between home and health. In Latvia, only limited research targeting the health and home situation of very old people is available. Consequently, the aim of this study was to describe how the home environment and aspects of health have changed over nine years between 2002 and 2011 for very old
A new spectrometer for studying photoinduced fragmentation has been designed and commissioned. The instrument produces a detailed view of the energy and angular emission of fragments, which in the case of small molecules can be related to their geometry at the moment of dissociation. The spectral profiles for single, double and triple ion coincidences are analyzed in terms of molecular alignment,
OBJECTIVES: The aim of this study was twofold: (i) to evaluate the air levels of N-nitrosamines in the Swedish rubber industry and (ii) to estimate the risk of symptoms and changed levels of immunologic markers in relation to these levels.METHODS: Using adsorption tubes, we collected samples of N-nitrosamines in the breathing zone of 96 rubber workers and analyzed them with liquid chromatography t
During the stress response adrenal medullary chromaffin cells release catecholamines to the bloodstream. Voltage-activated calcium channels present in the cell membrane play a crucial role in this process. Although the electrophysiological and pharmacological properties of chromaffin cell calcium channels have been studied in detail, the molecular composition of these channels has not been defined
Forest leaf area index (LAI), is an important variable in carbon balance models. However, understory vegetation is a recognized problem that limits the accuracy of sate I lite-estimated forest LAI. A canopy reflectance model was used to investigate the impact of the understory vegetation on LAI estimated from reflectance values estimated from satellite sensor data. Reflectance spectra were produce
Calbindin D-28k, a highly conserved protein with Ca2+-sensing and Ca2+-buffering capabilities, is abundant in brain and sensory neurons. This protein contains six EF-hand subdomains, four of which bind Call with high affinity. Calbindin D28k can be reconstituted from six synthetic peptides corresponding to the six EF-hands, indicating a single-domain structure with multiple interactions between th

Iceland is known for its remote location and rough beauty. In their seclusion, the Icelanders have built an independent and peaceful country. They are undeniably a very unique nation, where police officers are not allowed to carry guns, except on special occasions. The society displays a relaxed attitude towards prisons, which are built without concrete walls around. However, faced with the immens
