Fluxes of methane, CH4, were measured with the eddy covariance (EC) method at a small boreal lake in Sweden. The mean CH4 flux during the growing season of 2013 was 20.1 nmol m−2 s−1 and the median flux was 16 nmol m−2 s−1 (corresponding to 1.7 mmol m−2 d−1 and 1.4 mmol m−2 d−1). Monthly mean values of CH4 flux measured with the EC method were compared with fluxes measured with floating chambers (
In this group we study how metastatic processes depend on suppression of the immune response and how the immune system actually instead promotes breast cancer metastasis. The research has a strong translational character with clinical collaborations and primary material as base in all projects. The focus is on immunosuppressive cell populations and metastatic processes in breast cancer. Understand
Our research is focused on the regulation of the complement system in health and disease. Complement is crucial part of innate immunity and thus protects host from infections and contributes to removal of dying cells. We study involvement of complement in pathology of rheumatic and inflammatory diseases as well as several types of cancer. Further, we investigate strategies developed by bacterial
This thesis examines the effect of social origins (parents’ class) on left-right orientation. By examining the preferences of the socially mobile, the thesis estimates whether their preferences are more similiar to immobile members of the origin class, or to immobile members of the destination class. To estimate this correctly, the thesis utilizes the diagonal reference model developed by Sobel. T
Osteoarthritis is a chronic degenerative joint disease, and a rapidly growing cause of musculoskeletal disability, chronic pain, and reduced quality of life in an ageing European population. Our aims are to gain novel insights into osteoarthritis - its etiology, occurrence, natural history, treatments, prediction, disease monitoring, and disease burden - to allow for better care, decision making,
Twelve years ago, eleven European countries voluntarily abandoned their home currencies and joined the Euro. The founding fathers of the Euro believed that creation of the common currency would strengthen integration among the members and catalyze economic convergence progress within the common currency area. This study examines this issue in detail. I focus on labor productivity convergence and s
The goal of this study is to investigate the applicability of asymmetrical flow field-flow fractionation (AsFlFFF)–multi angle laser light scattering (MALLS), and to develop a method for analysis of cationic potato amylopectin (CPAP) having ultrahigh molecular mass (UHMr). Use of the aqueous carrier having low salt content (3 mM NaN3) resulted in a distortion in AsFlFFF fractograms of CPAP with a
The Swedish Stroke Register (Riksstroke) was founded in 1994. Riksstroke includes registration of acute stroke, with a follow up after 3 months and 1 year. The Stroke policy and quality register research group has several ongoing projects based on data from Riksstroke, and in many studies also using data record linkage to other national registers and data bases. The thesis of Teresa Ullberg expl
Background: Malaria kills almost 1 million people every year, but the mechanisms behind protective immunity against the disease are still largely unknown. Methodology/Principal Findings: In this study, surface plasmon resonance technology was used to evaluate the affinity (measured as kd) of naturally acquired antibodies to the Plasmodium falciparum antigens MSP2 and AMA1. Antibodies in serum samp
Moraxella catarrhalis is a human-specific commensal of the respiratory tract and an opportunistic pathogen. It is one of the leading cause of otitis media in children and of acute exacerbations in patients with chronic obstructive pulmonary disease, resulting in significant morbidity and economic burden. Vaccines and new immunotherapeutic strategies to treat this emerging pathogen are needed. Comp
Streptococcus pyogenes is an exclusively human pathogen that can provoke mild skin and throat infections but can also cause fatal septicemia. This gram-positive bacterium has developed several strategies to evade the human immune system, enabling S. pyogenes to survive in the host. These strategies include recruiting several human plasma proteins, such as the complement inhibitor, C4b-binding prot
The laboratory consists of a XenX x-ray irradiator (XStrahl) for experimental radiobiology, with supporting equipment for cell culture applications, such as laminar flow cabinets, CO2 incubators, and a hypoxia workstation. The XenX unit is designed as a radiotherapy machine in miniature. It consists of a 225 kV x-ray source, mounted on a rotatable gantry allowing irradiation of specimens from all The laboratory consists of a XenX x-ray irradiator (XStrahl) for experimental radiobiology, with supporting equipment for cell culture applications, such as laminar flow cabinets, CO2 incubators, and a hypoxia workstation.

Bone morphogenetic proteins (BMPs) are expressed and secreted during fracture repair. Although they are likely to be required for this process, little is known about their physiological role in bone regeneration. Noggin is a protein that specifically binds and inactivates several BMPs, It plays fundamental roles during early embryonal development and limb morphogenesis by this BMP-inactivating act
Although carbonate-carbon (C), an integral part of biochar-C, contributes to the liming properties of that material, it also interferes with the estimation of the stable organic C fraction in biochars. In this study, four methods were compared in order to quantify the carbonate-C in biochars: two direct (a titrimetric procedure and thermogravimetric analysis, TGA), and two indirect (acid treatment
