In this study, we first determined the low molecular weight dissolved organic carbon (LMW DOC) concentration-dependent kinetics of soil respiration in a temperate grassland soil sampled on successive occasions. We then used the established relationship to estimate in situ LMW DOC concentrations from basal respiration measurements. C-14-labelled glucose was used as a model substrate and was added t

The purpose of the present study was to investigate the amplifying function of the nucleus accumbens septi region (NAS) in 6-hydroxydopamine (6-OHDA)-induced rotational behaviour by implanting fetal dopamine (DA)-rich mesencephalic cell suspensions unilaterally in the NAS of rats previously subjected to combined mesostriatal (MS) and NAS 6-OHDA lesions. First, all the rats received a unilateral 6-

Recent work has uncovered a role of the microRNA (miRNA) miR-29 in remodeling of the extracellular matrix. Partial bladder outlet obstruction is a prevalent condition in older men with prostate enlargement that leads to matrix synthesis in the lower urinary tract and increases bladder stiffness. Here we tested the hypothesis that miR-29 is repressed in the bladder in outlet obstruction and that th

BACKGROUND: Arsenic in drinking water causes severe health effects. Indigenous people in the South American Andes have likely lived with arsenic-contaminated drinking water for thousands of years. Inhabitants of San Antonio de los Cobres (SAC) in the Argentinean highlands generally carry an AS3MT (the major arsenic-metabolizing gene) haplotype associated with reduced health risks due to rapid arse

In this paper, we show how studies of fracture mineral paragenesis, their orientation and Ar-40/Ar-39 geochronology can be applied in order to recognise the brittle tectonothermal evolution in an area. Samples were selected from nearly 18 km of drill cores from the upper I km of the Fennoscandian Shield obtained during the site investigation for a repository of spent nuclear fuel in Forsmark, cent

Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. The aim of this study was thus to evaluate the prevalence of allergic reactions to a mix of textile dyes consisting of 8 disperse dyes: Disperse (D) Blue 35, 10

Human trafficking is the world’s third largest organized crime after the illegal trade in arms and drugs. It is a growing problem in our increasingly globalized world and people are daily transported between countries to be exploited for different purposes. Not even Sweden is spared from this cynical business, although we may not hear much about it. The aim of this study was to investigate how Swe

With a worldwide increase in climate-related disasters and the global temperature on the rise, the effects of climate change are already being felt. Among those most at risk are the poor in developing countries, often living in informal settlements or „slums‟. In order to reduce associated risks and strengthen people‟s own coping capacities, there is an urgent need for knowledge about the factors

Freshwater of good quality is important, even necessary, for human society as well as natural ecosystems to function. However, the uneven distribution of freshwater globally together with other problems such as over-population and pollution all contribute to water stress and water scarcity in many countries. These issues are getting worse and worse. A growing number of companies and organizations

This thesis examines and analyses the relationship between the principle of complementarity and the principle of universal jurisdiction. The establishment of the International Criminal Court provides for the first time in history a permanent international criminal institution. One of the most important principles on which the ICC is built upon is the principle of complementarity. The road towards

The international character that surrounds the shipping industry has traditionally meant that rules regarding the public law of the sea or the private maritime law are internationally regulated through regulations, state practice, international conventions or international customary law. Since the 1970s, there has been an increasing concern for both the marine environment and the safety onboard sh

Context. In 2005, fusions between the androgen-regulated transmembrane protease serine 2 gene, TMPRSS2, and E twenty-six (ETS) transcription factors were discovered in prostate cancer. Objective: To review advances in our understanding of ETS gene fusions, focusing on challenges affecting translation to clinical application. Evidence acquisition: The PubMed database was searched for reports on ETS

Background: Sex pheromones are essential in moth mate communication. Information on pheromone biosynthetic genes and enzymes is needed to comprehend the mechanisms that contribute to specificity of pheromone signals. Most heliothine moths use sex pheromones with (Z)–11–hexadecenal as the major component in combination with minor fatty aldehydes and alcohols. In this study we focus on four closely

The formation of lumps during large scale wetting of spray dried powders is a common problem in the industry. The result is a large energy demand if an efficient mixing is to be achieved at the industrial scale. If more knowledge regarding the phenomena governing lump formation is obtained, the unit operation could be optimized and made more efficient. As a part of increasing the understanding of

Background: Functional and morphological changes of the heart influence blood flow patterns. Therefore, flow patterns may carry diagnostic and prognostic information. Three-dimensional, time-resolved, three-directional phase contrast cardiovascular magnetic resonance (4D PC-CMR) can image flow patterns with unique detail, and using new flow visualization methods may lead to new insights. The aim o

Since their discovery more than 70 years ago antibiotic drugs have been efficient tools for treating bacterial infections, and their use has reduced the number of fatalities and the suffering from bacterial diseases. However, the use of antibiotics may lead to resistance to the same or other antibiotics. The risk of resistance appears to be larger in veterinary medicine, since antibiotics have bee

Chromosomal instability is a known hallmark of many cancers. DNA polymerases represent a group of enzymes that are involved in the mechanism of chromosomal instability as they have a central function in DNA metabolism. We hypothesized that genetic variation in the polymerase genes may affect gene expression or protein configuration and by that cancer risk and clinical outcome. We selected four gen

The aim of this article is to offer an object lesson in how historians could make use of feature film as primary source material if they were to use the analytical tools developed in the field of film studies and by historians who started to work with film in the 1970s and 1980s. My own work on representations of maidservants in Swedish feature films in the 1930s and 1940s is used as a case in poi

Lipid bilayers are of interest in applications where a cell membrane mimicking environment is desired. The performance of the lipid bilayer is largely dependent on the physical and chemical properties of the component lipids. Lipid bilayers consisting of phytanoyl lipids have proven to be appropriate choices since they exhibit high mechanical and chemical stability. In addition, such bilayers have

Context: The insulin response to meal ingestion is more rapid in the morning than in the afternoon. Whether this is explained by a corresponding variation in the incretin hormones is not known. Objective: Assess islet and incretin hormones after meal ingestion in the morning versus afternoon. Design, Settings and Participants: Ingestion at 8am and at 5pm of a standardized meal (524 kcal) in health
