BACKGROUND: Is cancer related to hypertension and blood pressure? Do antihypertensive drugs promote cancer? Do antihypertensive drugs protect against cancer? We previously analysed the frequency of cardiovascular mortality and morbidity in elderly people who participated in the Swedish Trial in Old Patients with Hypertension 2 (STOP-Hypertension-2). We have also looked at the frequency of cancer i

The problem of continuous-time process parameter identification is considered. Filtered input-output process signals are used to create a linear differential equation governed by the same continuous-time process parameters. The estimation scheme is implemented by sampling the filtered signals and using a recursive least squares algorithm (RLS). The choice of filter leads to different parameter con

Sustainable agriculture requires nutrient management options that lead to a profitable crop yield with relatively low nitrogen (N) losses to the environment. We studied whether the addition of contrasting organic amendments together with inorganic fertilizer can promote both requirements simultaneously. In particular we studied how the chemical composition of organic amendments affects the biomass

Migratory connectivity describes to which degree different breeding populations have distinct (non-overlapping) non-breeding sites. Uncovering the level of migratory connectivity is crucial for effective conservation actions and for understanding of the evolution of local adaptations and migratory routes. Here we investigate migration patterns in a passerine bird, the great reed warbler Acrocephal

Background: The production of ethanol and other fuels and chemicals from lignocellulosic materials is dependent of efficient xylose conversion. Xylose fermentation capacity in yeasts is usually linked to xylose reductase (XR) accepting NADH as cofactor. The XR from Scheffersomyces stipitis, which is able to use NADH as cofactor but still prefers NADPH, has been used to generate recombinant xylose-

The urokinase-type plasminogen activator receptor (uPAR) is a non-integrin vitronectin (VN) cell adhesion receptor linked to the plasma membrane by a glycolipid anchor. Through structure-function analyses of uPAR, VN and integrins, we document that uPAR-mediated cell adhesion to VN triggers a novel type of integrin signalling that is independent of integrin-matrix engagement. The signalling is ful

Quantification and mapping possibilities of lithium in geological material, by Nuclear Reaction Analysis (NRA), was evaluated at the Lund Ion Beam Analysis Facility (LIBAF). LiF and two Standard Reference Materials, (SRM 610 and SRM 612) were used in the investigation. The main part of the data was obtained at the beam energy 635keV studying the high Q-value reaction 7Li(p, α)4He, but reaction yie

MicroRNAs are able to modulate gene expression in a range of diseases. We focused on microRNAs as potential contributors to the pathogenesis of ascending aorta (AA) dilatation in patients with stenotic tricuspid (TAV) or bicuspid aortic valve (BAV). Aortic specimens were collected from the ‘concavity’ and the ‘convexity’ of mildly dilated AAs and of normal AAs from heart transplant donors. Aortic

Nutrigenetics considers the influence of individual genetic variation on differences in response to dietary components, nutrient requirements and predisposition to disease. Nutrigenomics involves the study of interactions between the genome and diet, including how nutrients affect the transcription and translation process plus subsequent proteomic and metabolomic changes, and also differences in r

Adult neural stem/progenitor cells (NSPs) are multipotent and self-renew over an extensive period of time. Transformation events in such cells, such as genetic or epigenetic alterations can result in brain tumors. One goal of research on brain tumors is to identify which regulators are impaired during tumor initiation, development and maintenance in order to understand the origin of brain tumors a

Barns internetanvändning äger i stor utsträckning rum i en kommersiell miljö där reklam och försäljning av virtuella föremål är ständigt närvarande. Genom att kombinera publikforskning, produktionsforskning samt textanalys (observationer online och dokumentanalys) bidrar denna avhandling till en kritisk förståelse av internet som en plats för barns vardagliga aktiviteter och deltagande, och som enChildren’s daily internet usage takes place to a large extent in a commercial environment, where advertising and the sale of virtual goods are ever-present parts of the online experience. The overall goal of this thesis is to contribute to a critical understanding of children’s commercial online environment as spaces for children’s everyday life activities and participation, and as spaces for comm

Aim: Pseudomyxoma peritonei (PMP) is a rare disease characterized by the abundance of mucus in the abdomen without extra-peritoneal growth. Methods: Our patients with PMP have been treated with cytoreduction and hyperthermic intraperitoneal chemotherapy since 1996. The clinical and histopathological features of PMP and the relation of these features with disease-free interval and survival were ass

OBJECTIVE: The late revelation of ovarian cancer ensures it as the leading cause of death among gynecologic cancers. Cytoreductive surgery (CRS) and intravenous (i.v.) chemotherapy have been the cornerstone for a long time to treat this disease. More recently, the modality of intraperitoneal administration of chemotherapy under hyperthermic conditions (HIPEC) has been added. This review surveys th

Introduction Simulation-based studies indicate that crisis checklist use improves management of patients with critical conditions in the emergency department (ED). An interview-based study suggests that use of an emergency manual (EM) - a collection of crisis checklists - improves management of clinical perioperative crises. There is a need for in-depth prospective studies of EM use during clinica

Background: Obsessive-compulsive disorder (OCD) has been associated with a broad range of health-related issues. Unhealthy lifestyle habits such as physical inactivity, an unhealthy diet, smoking, and alcohol consumption are hypothesized to contribute to this association. However, the lifestyle habits of individuals with OCD have been scarcely investigated. In this international survey, we explore

In the course of 2000s, the region of Campania in southern Italy and its capital city Naples became global icons of waste mismanagement after the images of piles of rubbish occluding their urban areas hit the headlines. Conventional explanations, in Italy and elsewhere, pointed to administrative failure, cultural backwardness and mafia infiltration as the main causes of waste mishandling. In the s

Background: Intracerebral transplantation of human induced pluripotent stem cells (iPSCs) can ameliorate behavioral deficits in animal models of stroke. How the ischemic lesion affects the survival of the transplanted cells, their proliferation, migration, differentiation, and function is only partly understood. Methods: Here we have assessed the influence of the stroke-induced injury on grafts of

5-Fluorouracil (5FU) is a fluoropyrimidine used for the treatment of solid tumors. 5FU is a precursor of dTTP and UTP during biogenesis, and it interferes with both DNA and RNA metabolism. The RNA exosome, a multisubunit complex with ribonucleolytic activity, has been identified as one of the targets of 5FU in yeast. Studies in human cells have shown that the catalytic subunit of the nuclear exoso
