In the developed countries the public expect society to be prepared for, and step in, if something out of the ordinary happens. This public pressure appears to have increased the demand for crisis preparedness planning. In crisis management the local authority serves as the first line of defence and will more or less always be involved in responding to crises. It is therefore important to study ho
Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. However, in the last two decades, due to the depletion of the stratospheric ozone layer, increasing levels of ultraviolet-B radiation (280-3
Aerosol particles in the atmosphere are important in several aspects. Some major aerosol constituents that are deposited in ecosystems are acidic or fertilisers and some minor or trace constituents are toxic. Aerosol particles are also involved in the earth’s radiation balance, both directly by scattering the sunlight and indirectly by influencing the clouds. All these effects are influenced by th
Popular Abstract in Swedish Proteiner är den huvudsakliga beståndsdelen i levande celler. Proteiner består av långa kedjor av aminosyror som sitter ihop med peptidbindningar och vecklar ihop sig till komplicerade tre dimensionella strukturer. Proteiner är involverade i praktiskt taget alla mekanismer och funktioner i cellen. När man studerar hela proteinsammansättningen i t.ex. ett organ, en speciMembrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. a cell or a tissue, at a certain time point and "proteomics" is the large scale study of these prote
The four surprisingly complex visual sensory organs of cubomedusae, the rhopalia, contain each six eyes of four morphologically different types, two of which are camera-type eyes. This means that the evolutionary basal nervous system of cubomedusae must process the visual signals received from a total of 24 rhopalial eyes. Since the neuronal organization of the rhopalia is obscure, the role of the
Popular Abstract in Swedish Ett ökade förbrukningen av fossila bränslen kommer att accelerera den globala uppvärmningen med oöverskådlig inverkan på oss och vår miljö. Utvecklingen av alternativa, förnybara och miljömässigt rena energiformer är därför helt essentiell. En möjlig lösning är att skapa artificiell fotosyntes, där solenergi omvandlas till bränsle (till exempel vätgas) i en process där A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. hydrogen gas) by splitting water molecules. However, i
Climate and Trade Policies in a Post-2012 World is a collection of short forward-thinking articles by leading experts on the relationship between trade and climate change policies. The idea for developing this publication was conceived at the “International Workshop on Post-2012 Climate and Trade Policies”, jointly organized in September 2008 by the United Nations Environment Programme (UNEP) and
Treatment of Parkinson's disease is complicated by a high incidence of L-DOPA-induced dyskinesias (LID). Strategies to prevent the development of LID aim at providing more stable dopaminergic stimulation. We have previously shown that deuterium substitutions in the L-DOPA molecule (D3-L-DOPA) yield dopamine that appears more resistant to enzymatic breakdown. We here investigated the effects of D3-
Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic or episodic inflammation in many different organ systems, activation of leukocytes and production of pro-inflammatory cytokines. The heterodimer of the cytosolic calcium-binding proteins S100A8 and S100A9 (S100A8/A9) is secreted by activated polymorphonuclear neutrophils (PMNs) and monocytes and serves as a seru
In diverse and productive habitats, predaceous arthropods are expected to frequently encounter dangerous conspecifics and heterospecifics. This should make quick and accurate discriminations between species and sexes adaptive. By simultaneously sampling both visual cues and pheromones, and by utilizing stringent species- and sex-specific visual recognition templates, an individual should be able t
Objective: To study the use of major and alternative coreceptors by HIV-1 isolates obtained from paired plasma and cerebrospinal fluid (CSF) samples. Design: Paired plasma and CSF isolates from HIV-1-infected individuals with varying clinical, virologic, and immunologic parameters were assessed for the ability to infect indicator cells expressing a panel of coreceptors with documented expression i
Folate's role in breast cancer development is controversial. Not only estrogen receptor (ER) alpha status, but also ERbeta status of tumors may have confounded results from previous epidemiological studies. We aimed to examine associations between plasma folate concentration and postmenopausal breast cancer defined by ER status. This nested case-control study, within the Malmö diet and cancer coho
A sudden unilateral loss or impairment of vestibular function causes vertigo, dizziness, and impaired postural function. In most occasions, everyday activities supported or not by vestibular rehabilitation programs will promote a compensation and the symptoms subside. As the compensatory process requires sensory input, matching performed motor activity, both motor learning of exercises and matchin
Background Melanoma risk is related to sun exposure; we have investigated risk variation by tumour site and latitude. Methods We performed a pooled analysis of 15 case-control studies (5700 melanoma cases and 7216 controls), correlating patterns of sun exposure, sunburn and solar keratoses (three studies) with melanoma risk. Pooled odds ratios (pORs) and 95% Bayesian confidence intervals (CIs) wer
Background: Previous studies indicate that there may be infant gender differences in cytokine expression associated with differences in neonatal morbidity. Objective: We tested the hypothesis that umbilical cord interleukin-1 receptor antagonist (IL-1ra) correlates with infant gender and neonatal outcome in preterm infants. Study Design: IL-1ra was measured in cord blood taken from 58 preterm infa
Background: Erectile dysfunction is associated with, and may be the first sign of coronary artery disease. We aimed to assess whether men with erectile dysfunction but without cardiovascular disease have reduced coronary flow reserve, as a sign of early coronary atherosclerosis. Methods: We investigated 12 men aged 68-73 years with erectile dysfunction, and 12 age-matched controls. Erectile functi
Aim The aim of this trial was to prospectively evaluate the effect of follow-up at a nurse-led heart failure clinic on mortality, morbidity and self-care behaviour for patients hospitalised due to heart failure for 12 months after discharge. Methods A total of 106 patients were randomly assigned to either follow-up at a nurse-led heart failure clinic or to usual care. The nurse-led heart failure c
Objectives. Prospective studies have indicated that hyperinsulinaemia/insulin resistance is a risk factor for ischaemic heart disease (IHD), the risk decreasing with time of follow-up. Few studies have so far investigated the role of hyperinsulinaemia in the prediction of long-term total mortality. Setting.

Introduction. Obstructive sleep apnea is defined as repetitive (≥5/hour) partial or complete cessation of breathing during sleep. Whereas obstructive sleep apnea is often considered to be associated with sexual problems in men, studies concerning effects of obstructive sleep apnea on female sexual function and distress are sparse. Aim. To investigate sexual dysfunction and sexual distress in fem
