Zooplankton have evolved several mechanisms to deal with environmental threats, such as ultraviolet radiation (UVR), and in order to identify strategies inherent to organisms exposed to different UVR environments, we here examine life-history traits of two lineages of Daphnia pulex. The lineages differed in the UVR dose they had received at their place of origin from extremely high UVR stress at h
Background: Whilst tall stature has been related to lower risk of vascular disease, it has been proposed as a risk factor for atrial fibrillation. Little is known about other anthropometric measures and their joint effects on risk of atrial fibrillation. Objectives: We aim to investigate associations and potential joint effects of height, weight, body surface area (BSA) and body mass index (BMI) w
To characterize type 2 diabetes (T2D)-associated variation across the allele frequency spectrum, we conducted a meta-analysis of genome-wide association data from 26,676 T2D case and 132,532 control subjects of European ancestry after imputation using the 1000 Genomes multiethnic reference panel. Promising association signals were followed up in additional data sets (of 14,545 or 7,397 T2D case an
Pathogenesis of abdominal aortic aneurysm (AAA) is unclear. The aim of this study was to evaluate inflammatory and hemodynamic plasma biomarkers as predictors for AAA in the prospective longitudinal cohort of middle-aged individuals from the cardiovascular cohort of the Malmö Diet and Cancer Study ( n=5551; 1991-94). C-reactive protein, cystatin C, copeptin, N-terminal pro-B-type natriuretic pepti
Introduction: Islets synthesise and secrete numerous peptides, some of which are known to be important regulators of islet function and glucose homeostasis. In this study, we quantified mRNAs encoding all peptide ligands of islet G protein-coupled receptors (GPCRs) in isolated human and mouse islets and carried out in vitro islet hormone secretion studies to provide functional confirmation for the
Objective: Atypical responses to sensory stimuli are common features of autism spectrum disorders (ASD). Consequently, atypical sensory reactivity (SR) is now a diagnostic feature of ASD. Quantitative genetic research on ASD has overlooked these symptoms, however. We therefore investigated the association between autistic traits and SR using twin methods. Method: Autistic traits and SR were assess
The DNA sequencing of a series of living organisms has elucidated many biological problems. But the internal atomic and electronic evolution of DNA remains to be mapped in detail. RNA and DNA now appear to be the prime determinants of biological evolution leading to the sudden appearance of novel organism structures and functions that emerge “ready made” as a surprise to the organism. This has bee
Genome-wide association analysis advanced understanding of blood pressure (BP), a major risk factor for vascular conditions such as coronary heart disease and stroke. Accounting for smoking behavior may help identify BP loci and extend our knowledge of its genetic architecture. We performed genome-wide association meta-analyses of systolic and diastolic BP incorporating gene-smoking interactions i
Abstract Author: Marie Andersson Titel: Who is listening to us? A qualitative study with assistant nurses about their work situation from their point of view. Supervisor: Helena Hansson Assessor: Håkan Johansson When I was practice at a nursing home setting, I noticed that the assistant nurses were faced with different types of ethical dilemmas. The problem with these dilemmas was that they wer
Authors: Lisa Grönlund and Jenny Jalvelius Title: Body & Mind – A discourse analysis of two participants’ constructions of transsexualism within the frame of a public investigation [translated title] Supervisor: Mats Hilte Assessor: Anna Meeuwisse Lately transsexualism and transsexuals have received increased attention in media and in the field of research and we have aimed to contribute t
Populärvetenskaplig sammanfattning: Bekämpningsmedel; bra för maten, dåligt för vattnet? Att ha tillgång till rent vatten är livsviktigt för människan. Trots detta saknar nästan hälften av jordens invånare tillgång till vatten av hög kvalitet. Eftersom mycket av det vatten vi använder tas upp ur marken, från grundvattnet, så är det viktigt att inte förorena grundvattnet med ämnen som kan vara skadThis bachelor thesis, written at the Department of Earth and Ecosystem Sciences at Lund University in 2010, discusses the movement of pesticides in the ground. The aim of the study is to examine the potential impact that the ground properties have on the movement of pesticides to and with groundwater. The ground properties that will be considered are the hydraulic conductivity and the depth of the
Am I allowed to help? – The care manager’s new dilemma Authors: Thea Nilsson Svegard and Helena Rülf Title: Am I allowed to help? – The care manager’s new dilemma Supervisor: Staffan Blomberg Assessor: Alexandru Panican The aim of this essay was to examine how care managers working with elderly look upon their own role in relation to customer-choice. The customer-choice reform is spreading rapi
The purpose of this study was to examine the collaboration between organizations that care for mentally retarded persons with added psychiatric problems when they have the need of institutional care in the psychiatry. I have both looked at which kinds of collaboration there are and then looked closer on the coordinated care plan. I’ve also looked at how the organizations adjust themselves after th
Den globala uppvärmningen orsakar stigande havsnivåer till följd av avsmältning av landis samt termisk expansion av vattnet. Allvarliga konsekvenser befaras till följd av detta, stora landarealer kan komma att svämmas över vilket bland annat kan bidra till klimatflyktingar. Om havsnivån ökar drastiskt står vi i Sverige inför väldiga utmaningar eftersom stora delar av befolkningen är bosatta längs
Utsläppen av växthusgaser, som till exempel koldioxid, i atmosfären leder till ökade temperaturer runt om på jorden. I tidningarna kan man läsa att den ökande temperaturen leder att glaciärer och polarisar smälter. Men ett annat problem med klimatförändringarna som ofta hamnar i skymundan i media är hur ekosystemen påverkas av de ökande temperaturerna. I det här arbetet försöker jag visa hur den öThe earth’s climate is undergoing vast and rapid chages due to the increased greenhouse gases in the atmosphere. These changes in the atmosphere are affecting life on earth in many different ways. This degree thesis attempts to quantify the changes in vegetation phenology in Europe during the last 23 years and link these changes to changes in temperature. The phenological parameters that were stud
