Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. Nowadays, the cement industry produces cements with increasing amounts of supplementary cementitious materials (SCMs) to

Cue-conflict experiments were performed to study the compass calibration of one predominantly diurnal migrant, the dunnock (Prunella modularis), and two species of nocturnal passerine migrants, the sedge warbler (Acrocephalus schoenobaenus), and the European robin (Erithacus rubecula) during autumn migration in South Sweden. The birds' orientation was recorded in circular cages under natural clear

Electroconvulsive therapy (ECT) is a very efficient treatment for severe depression. However, cognitive side effects have raised concern to whether ECT can cause cellular damage in vulnerable brain regions. A few recent animal studies have reported limited hippocampal cell loss, while a number of other studies have failed to find any signs of cellular damage and some even report that electroconvul

Popular Abstract in Swedish Projektet har for avsikt att vardera den elektriska overledningen mellan hjartats formak och hur forsamring av denna overledning bidrar till uppkomsten av attackvis pakommande formaks- flimmer. Studierna har anvant sig av ekg- registreringar fran kroppsytan, registreringar fran hjartats insida, anatomiska dissektionsstudier och djurexperiment. Slutsatser 1. OfiltreratThe aim of this thesis was to evaluate the role of interatrial conduction defects in the genesis of lone paroxysmal atrial fibrillation (AF) using combined approach of non-invasive signal-averaged P-wave ECG, invasive electrophysiological (EP) studies, anatomical studies and animal experiments. Non-filtered signal-averaged P-wave ECG revealed irregularities in orthogonal P-wave morphology and the

Popular Abstract in Swedish Svensk sammanfattning Slaganfall (stroke), hjärtstillestånd eller överdosering av insulin är tillstånd som leder till en minskning av syre- och/eller glukos till hjärnvävnaden. Då tillförseln av glukos och syrgas minskar, kan cellerna inte längre upprätthålla en normal energiproduktion. Eftersom en stor del av energin går åt till bevara den spänning som finns över cellIn this thesis mechanisms of neuronal damage were investigated in an experimental stroke model i.e focal ischemia. The influence of SD-induced calcium transients on neuronal damage were studied in animals with reduced energy supply. The influence of bioenergetic failure on K+e concentration and Ca2+e homeostasis were also investigated in transient focal ischemia. Moreover, the free radical formati

Popular Abstract in Swedish Det innersta cellagret i blodkärl (endotelet) kan frisätta både kontraktila (kärlsammandragande) och relaxerande (kärlvidgande) faktorer. När receptorer på endotelet stimuleras med till exempel acetylkolin så frisätts relaxerande faktorer. Dessa faktorer verkar vara åtminstone tre till antalet och två av dessa har identifierats som kväveoxid och prostacyclin. Den tredjeVasodilator responses to endothelium-derived hyperpolarizing factor (EDHF) and anandamide in isolated arteries were investigated. A combination of the potassium channel blockers charybdotoxin and apamin inhibits EDHF-mediated relaxations. Experiments in which charybdotoxin or apamin was substituted with other potassium channel inhibitors indicated that small- and intermediate-conductance calcium-a

Popular Abstract in Swedish Astma och rökarsjuka, eller mer korrekt kronisk obstruktiv lungsjukdom (KOL), är två vanliga sjukdomar som karakteriseras av att de drabbade tidvis har svårt att andas. Denna andnöd orsakas av att luftvägarna drar ihop sig. Mediciner som motverkar detta och istället vidgar luftvägarna är därför viktiga för patienter som lider av astma eller KOL. Det finns idag flera medCapsazepine and similar compounds, capsazepinoids, were shown to be general inhibitors of agonist (leukotriene D4, histamine, acetylcholine, prostaglandin D2) evoked constriction of human small airway preparations. The mechanism of action remains to be elucidated, but established bronchodilator principles, e.g. beta2-adrenoceptor agonism, as well as TRPV1 antagonism were shown to be less likely. F

OBJECTIVE - Whole-grain foods are touted for multiple health benefits including enhancing insulin sensitivity and reducing type 2 diabetes risk Recent genome-wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) associated with fasting glucose and insulin concentrations in individuals free of diabetes We tested the hypothesis that whole-grain food intake an

Objectives: To assess the contribution of out-of-home (OH) energy and nutrient intake to total dietary intake, and to compare out-versus in-home nutrient patterns among 27 centres in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Methods: Between 1995 and 2000, 36 034 participants aged between 35-74 years completed a standardized 24-h d

Aim: To evaluate the efficacy of two different Swedish screening procedures for early detection of congenital cataracts in comparison with no screening. Methods: Children born between January 1992 and December 1998 in Swedish regions with an established eye-screening routine procedure, diagnosed with congenital cataract, and operated on before 1 y of age, were included in a retrospective study. Ag

Several lines of evidence suggest that wetlands may be a major source of methylmercury (MeHg) to receiving waters, perhaps explaining the strong correlation between concentrations of waterborne MeHg and dissolved organic carbon (DOC) in regions such as northern Wisconsin. We evaluated the relative importance of wetland export in the MeHg budget of a wetland-dominated lake in northern Wisconsin usi

Questions: How will density-dependent and costly dispersal evolve in populations subject to local density regulation and environmental stochasticity? What type of density response will evolve, a strong threshold type response or a soft response gradually increasing dispersal? Method: An individual-based model including density dependence, environmental fluctuations, and population variation was us

Aims: The need to combine active employment and parenthood is a reality for many parents today. Knowing more about which work place factors are associated with better or worse health could help employers to form a work environment that provides optimal conditions to maintain or increase health and work engagement in this group. The aim of this study was to explore possible associations between dif

Nanoparticles are widely used in the pharmaceutical and food industries, but the consequences of exposure to the human body have not been thoroughly investigated. Apolipoprotein A-I (apoAI), the major protein in high-density lipoprotein (HDL), and other lipoproteins are found in the corona around many nanopartides, but data on protein structural and functional effects are lacking. Here we investig

Using ITS nrDNA sequence data, the Caloplaca cerina group (Teloschistaceae) is defined here as a monophyletic, but internally richly branched lineage. The group is also characterized by a combination of morphological and anatomical characters. Its internal lineages are supported by phenotypic characters in addition to ecology and distribution. Within the large C. cerina group, we have found at lea

Organohalogen compounds constitute one of the important groups of persistent organic pollutants (POPs). Among them, due to their long-term health effects, one should pay attention on organochlorine pesticides, polychlorinated biphenyls (PCBs) and perfluoroalkylated substances (PFASs). This paper is an attempt to answer the question about relation between the fact of cohabitation by couples expecti

The Sao Francisco Craton (SFC) is an Archaean craton that hosts a significant number of mafic intrusions. Previous attempts to date the igneous emplacement of these rocks are limited to a few dates of poor precision. Here, two dyke swarms from the Uaua Block in the northeastern portion of the craton were dated using U-Pb on baddeleyite (ID-TIMS) and zircon (SIMS). The older dyke swarm trends mainl

A prospective clinical cohort study was established to investigate the humoral immune response in middle ear fluids (MEF) and serum against bacterial surface proteins in children suffering from recurrent acute otitis media (rAOM) and chronic otitis media with effusion (COME), using Luminex xMAP technology. The association between the humoral immune response and the presence of Moraxella catarrhali
