The pseudo-Thellier technique was applied to recover relative palaeointensity (PT-RPI) estimates from four piston cores retrieved from a Holocene lake sediment sequence in the province of Smaland, central southern Sweden. A time-depth model between 11,000 and 450 cal BP was based on a combination of calibrated radiocarbon ages and the ages of established palaeomagnetic secular variation (PSV) feat
Purpose. Patients with soft tissue sarcomas (STS) are at increased risk of second primary malignancies, including a second STS, but distinction between metastases and a second primary STS is difficult. Patients and Methods. Array-based comparative genomic hybridization (aCGH) was applied to 30 multiple STS of the extremities and the trunk wall from 13 patients. Different histotypes were present wi
Experiments were performed on the central body rich-pilotlean (RPL) burner of a Siemens Industrial Turbomachinary 4th generation DLE combustor to observe the combustion changes that may occur when using fuels other than natural gas. Measurements were taken of temperatures at multiple points along the RPL body while hydroxyl (OH) radical distribution extending from the dump plane of the burner was

This article is dealing with the work of a Catholic St Joseph Sisters in the Nordic countries, particularly in Denmark and Sweden, from the sisters’ arrival in 1856 to the 1920:ies. These Catholic sisters belonged to a French congregation called La Congregation des Sœurs de Saint-Joseph de Chambéry, which was founded at the beginning of the nineteenth century and whose motherhouse was in Chambéry
Popular Abstract in Swedish En populärvetenskaplig sammanfattning Det faktum att vårt minne förändra's med åldern är ett välkänt och väldokumenterat fenomen. Vilka faktorer som bidrar till denna förändring och hur de samverkar för att påverka vårt minne är däremot till stora delar forfarande ett mysterium. Minnesforskare delar vanligtvi's upp vårt minne i flera olika minnessystem. Dessa dela's upThe aim of this thesis was to examine the importance of environmental, non-cognitive, and person-based variables for memory performance in old adults. Study I was conducted in cooperation with the Gerontology Research Centre and the Department of Psychology in Lund. The investigation included 69 people with an age-range from 55-94 years and examined if certain personality factors could explain th
Popular Abstract in Swedish Grupp A streptokocker (Streptococcus pyogenes) är bakterier som orsakar många vanliga infektioner som halsfluss och svinkoppor (impetigo). De kan också orsaka allvarliga infektioner som under 1900-talet blev alltmer ovanliga. I slutet av 1980-talet började dock allvarliga streptokockinfektioner bli vanligare igen. Det är oklart varför det har skett en ökning av aCell wall-attached proteins (CWPs) are important for the virulence of Gram-positive bacteria, but are also targets for the host immune system. CWPs have a conserved COOH-terminal region, responsible for cell wall-sorting. A pattern based on this conserved region was developed. The pattern identifies genes encoding CWPs, with high sensitivity and specificity, in whole genomes of Gram-positive bacte
Popular Abstract in Chinese 北极和亚北极地区对全球气候变化影响尤为重要。目前，北极地区正面临着变暖速度高于全球平均的现状。全球大约有50%的土壤碳储存在高纬度地区的土壤里，这些土壤碳主要分布于冻土层和泥炭层中。冻土层的解冻会使原先被冻结的土壤碳加速分解，产生温室气体，从而对全球变暖形成一个强烈的正反馈。与此同时，气温的增加可能会很大程度地影响植被在这些地区的生长和分布。动态生态系统模型是一种非常强大的工具，被用来研究气候变化对生态系统的影响，并且可以量化生态系统对大气的反馈信息。然而这些模型通常只关注大气、地表植被和土壤之间的水和碳的纵向转移，从而忽略了其在模型空间单元中的横向移动。这样可能会导致模型对于水和碳平衡的计算不够准确和全面，尤其在气候敏感的高纬度极地地区，这种偏差可能会更大。 本论文旨在解决动态生态系统模型中的这个局限性问题。基于目前最先进的动态生态The Arctic and Subarctic regions are of particular importance to the global climate change and are now experiencing a climate warming that is higher than the global average. Around 50% of the global soil carbon is stored in high latitude soils, especially in permafrost and peatland soils. Permafrost thawing, speeding up the decomposition of previously frozen soil carbon, is expected to result in s
Offenders who target children are a negative phenomenon in our society. These offenders are often seen as the worst of the worst of criminals and are therefore a priority for investigators trying to solve these crimes as fast as possible. The purpose of this thesis is to see if there are common denominators among these offenders in their modus operandi (MO) and their spatial patterns. If similar p
Filamentous fungi produce asexual dispersive spores (conidia), when conditions are not suitable for apical extension growth. Conidiation (the process by which conidia produced) in genus Penicillium has attracted considerable interest because of its wide usage in different areas. In addition, several Penicillium species are pathogenic toward humans and plants, causing crop spoilage as well as decay
Popular Abstract in Swedish En cell är den minsta beståndsdelen av det som vi definierar som liv. Cellen avgränsas av ett cellmembran som gör att rätt miljö, dvs rätt koncentration av alla nödvändiga molekyler, upprätthålls inuti cellen. Cellmembranet består bl a av olika slags fett, sk lipider. Många små molekyler kan fritt passera igenom membranet medan andra kräver specifika transportkanaler i The aquaporins (AQPs) belong to a family of water permeable membrane channels found in virtually all living organisms. Thirteen isoforms of mammalian AQPs are found, whereas in Arabidopsis thaliana 35 genes encoding AQPs are found. The AQPs are distributed in different organs, cell types and in different subcellular membranes. The aquaporins form homotetramers where each monomer functions as an in
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
Popular Abstract in Swedish Artrit karakteriseras av svullnad och värk i leder, ledförstöring och bindvävsförstoring. Denna binvävsförstoring kallas för Pannus och är en förtjockning av det normalt förekommande synovial membranet i en led. Normalt är synovial membranets uppgift att ge näring åt det intilliggande brosket som inte självt har någon blodförsörjning. Synovial membranet innehåller ocksåRheumatoid arthritis is a chronic, inflammatory and systemic disease characterised by joint destruction and pannus formation. To enlarge the understanding how pannus and granulation tissue are formed two animal models were used; one using cartilage wrapped in cotton and implanted into a rat air pouch (AP) and one where mBSA induced arthritis (AIA) was performed.

Popular Abstract in Swedish Höftfraktur är en vanlig skada, som huvudsakligen drabbar äldre kvinnor, och oftast orsakas av ett ringa våld. Det är vanlig orsak till funktionsnedsättning, sjuklighet och dödlighet hos de äldre. Både incidensen (antal nya fall per antal innevånare och år) av höftfrakturer och det totala antalet har ökat de senaste årtiondena. Höftfrakturer medför stora kostnader för sHip fractures are a common cause of morbidity and mortality in elderly patients, with a high risk of functional impairment and institutionalization. The incidence and number of hip fractures have increased during the recent decades and hip fractures consume considerable health-care resources. The incidence of hip fractures in Malmö, Sweden, 1992–95, is described in Paper I. The annual incidence pe
The electroenzymatic reactions of Trametes hirsuta laccase in the pure organic solvent dimethyl sulfoxide (DMSO) have been investigated within the framework for potential use as a catalytic reaction scheme for oxygen reduction. The bioelectrochemical characteristics of laccase were investigated in two different ways: (i) by studying the electroreduction of oxygen in anhydrous DMSO via a direct ele
Papanicolaou-stained cervicovaginal smears (Pap smears) are used to screen for cervical cancer. Since there is a lack of consensus in published reports respecting the efficacy of Pap-stained smears in BV diagnostics, there is a need to validate their use for diagnosis of BV. Slides from the international BV00 workshop were Pap stained and independently analyzed by four investigators under a phase-
BACKGROUND: Stroke after cardiac surgery is a clinical problem with often fatal or disabling outcome. To assess severity and probable outcome in affected patients only from clinical and radiological examinations is difficult. The glial-derived protein S100B has been suggested to be a marker of cerebral ischemia, and increased blood concentrations of S100B have been shown to correlate with size of
Purpose To collect data for the development of a more universally useful logistic regression model to distinguish between a malignant and benign adnexal tumor before surgery. Patients and Methods Patients had at least one persistent mass. More than 50 clinical and sonographic end points were defined and recorded for analysis. The outcome measure was the histologic classification of excised tissues
We hypothesized that voluntary wheel running results in increased secretion of oxytocin, a peptide involved in the stress response. An additional hypothesis was that prolonged exercise affects oxytocin levels in the heart, which is in line with the potential role of oxytocin in cardiovascular functions. Voluntary wheel running lasted 3 weeks and daily running distances increased progressively reac
Previous studies on the occurrence of catecholamines and serotonin in pancreatic islets using various histochemical and chemical methods have given widely different results. We therefore performed a comparative analysis of these amines in whole pancreas and islet tissue from hamster, guinea pig, rat, and mouse by the use of high performance liquid chromatography. Whole pancreas of guinea pig, hams
