Declines in the distribution and abundance of many farmland species during recent decades have been attributed to agricultural intensification. Agri-environment schemes are commonly used in Europe to reduce this loss of farmland biodiversity, but their effectiveness may depend on several external factors. In this thesis, I have used one such scheme, organic faming, as a landscape scale experiment
Enterostatin is a peptide formed in the stomach and intestine during the activation of pancreatic/gastric procolipase. Procolipase is a necessary cofactor for lipase. These two proteins contribute to the breakdown of dietary triglycerides in the intestine. Enterostatin has been found to act as a satiety factor, selectively inhibiting fat intake both through sites in the gastrointestinal tract and
Natural killer (NK) cells and T lymphocytes are the major effector cells that can recognize and kill tumor cells. NK cells have a constitutive cytotoxic activity and kill a wide spectrum of tumor cells while T cells recognize specific tumor antigens and need to be activated through their TCR to differentiate into cytotoxic T lymphocyte (CTL) killers or T helper cells. Interleukin-2 is the principa
Detta arbete avgränsas till att behandla energianvändning i småhus. Studien omfattar tre småhus som byggts för utställningen Bo92 i Örebro. Syftet med studien är att beräkna och ta fram kunskaper om den totala energiåtgången under en byggnads hela livscykel. Användningstiden för husen är antagen till 50 år.
The Goto-Kakizaki (GK) rat is a well-studied non-obese spontaneous type 2 diabetes (T2D) animal model characterized by impaired glucose-stimulated insulin secretion (GSIS) in the pancreatic beta cells. MicroRNAs (miRNAs) are short regulatory RNAs involved in many fundamental biological processes. We aim to identify miRNAs that are differentially-expressed in the pancreatic islets of the GK rats an
An intense, potentially tissue-damaging (noxious) stimulus may lead to enhanced pain sensation of subsequent noxious stimuli (hyperalgesia) and to the perceiving of innocuous stimuli as painful (allodynia). This is thought to result to a large extent from strengthening of synapses established by primary afferent fibers onto spinal cord dorsal horn neurons. Here we investigated, using the postembed
The reason for moving from one library system to another or from one generation of a library system to the next must be to improve the library's ability to serve its users in a better and more effective way. An integrated library system, today, is very complex and multi-moduled, which makes it difficult to distinguish one system from another. The article describes the long and bumpy road from the
In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. On the one hand, eye movements reflect human thought processes. It is easy to
Scholars within the Process school assume that cognitive and motivational aspects within the decision and integration processes may systematically effect the outcome of mergers and acquisitions. More specifically, it has been suggested that decision makers use heuristics for simplifying information processing which may introduce bias. The main aim of the present thesis is to add to the understandi
Early reperfusion in the setting of an ST-elevation myocardial infarction (STEMI) is of utmost importance. However, the effects of early versus late reperfusion in this patient group undergoing primary percutaneous coronary intervention (PCI) have so far been inconsistent in previous studies. The purpose of this study was to evaluate in a nationwide cohort the effects of delay from first medical c
The aims of this thesis were to identify microRNAs (miRNAs) with prostate cancer prognostic and diagnostic potential, to discover miRNAs with therapeutic capacity against prostate cancer, and to investigate if prostate specific antigen (PSA) is miRNA regulated. Prostate cancer is a globally spread disease with low mortality, but some patients develop an aggressive lethal form of prostate cancer w
Electricity has been regarded as a typical example of a general purpose technology and important for the surge both in energy productivity and overall productivity in the American economy in the 1920s. This view was challenged by Nicholas and Moser (2004) based on patent statistics. We argue that other methods are required for studying productivity effects and propose cointegration analyses. We de
Dwarf males occur in many unrelated groups of organisms. Among land plants they are unique to mosses. Moss dwarf males originate from male spores that land and germinate on the female where their final size is restricted to a few mm. Fertilization in mosses occur over short distances with swimming spermatozoids. Having the males growing as tiny epiphytes on the females facilitates fertilization, a
