BACKGROUND AND OBJECTIVES: Transfusion of blood products in particular older products is associated with patient morbidity. Previously, we demonstrated a higher incidence of acute lung injury in lipopolysaccharide-treated sheep transfused with stored blood products. As transfusion following haemorrhage is more common, we aimed to determine whether a 'first hit' of isolated haemorrhage would prec
Purpose – Cassava production surged noticeably in Southeastern Africa beginning in the 1990s. The purpose of this paper is to examine the commercial responses and food security consequences of cassava production growth in the region. Design/methodology/approach – The paper incorporates a mix of quantitative analysis, based primarily on original analysis of national farm household survey data, toge
Establishing a technically practical method to generate representative model catalysts for the use in characterizations and testing prior to catalyst implementation in chemical process units would allow for a more sophisticated understanding of the underlying catalytic mechanisms. As a step towards establishing such a method, generating non-agglomerated, spherical NiMo nanoparticles, with diameter
Oleaginous microorganisms provide an opportunity to produce oils without the use of arable land for cultivation of oil-containing plants. Oleaginous microorganisms are also capable of storing products of pharmaceutical interest alongside storing polymers, which could open new opportunities in the bioplastic industry. Oily yeasts have several advantages in comparison to alternatives; their doubling
In the area of physical activity recognition, there is a great demand for better understanding data and building useful models for data analysis. Many studies have focused on using machine learning algorithms, which provide high accuracy but are computationally expensive. However, few studies have tried to approach this problem with statistical methods. The purpose of this study is to investigate
The purpose of this thesis is to develop a blind spot detection system for increased safety and comfort for a biker. The solution is based on power-efficient small A111 radars, developed by Acconeer AB, which have a range up to seven meters while consuming only a few milliwatts. Sensor evaluation is performed for the intended use and from this, concepts are generated. These are tested to obtain t
Quantitative PCR (qPCR) is a commonly used method today in the fields of molecular diagnostics, forensic and food analysis. The real-time measurements of amplification and quantification of specific DNA molecules is one of many reasons why qPCR is the method of choice. However, presence of inhibitory compounds limit this method for example by interacting with either the DNA polymerase or the DNA t
Politiken har genom i historien ansetts vara manligt territorium. Fenomenet är även idag påtagligt i många delar av världen. När kvinnor därmed inte ges tillträde till det offentliga rummet tar sig deras samhällspåverkan till största del uttryck i den privata sfären. Synen på kvinnan som politisk har däremot lett till att dessa handlingar inte erkänts till fullo. Det finns även dem som menar att sThroughout history, politics has been dominated by men and the phenomenon still exists today in many parts of the world. When women are not given access to the public sphere, their social impact inevitably takes place in the private. Nevertheless, the view of the woman as non-political has led to these actions not being entirely recognized. There are also those who argue that this approach also ex
PURPOSE: To correlate quantification of collateral flow in aortic coarctation with the morphological visualization of the collateral vessels and to compare different approaches to measurement of collateral flow. MATERIALS AND METHODS: Thirteen children with coarctation were examined with T1-weighted spin-echo (T1-W SE) imaging and 3D contrast-enhanced magnetic resonance angiography (MRA). MR veloc
Background: In COPD, the balance between matrix metalloproteinases (MMPs) and their natural inhibitors [tissue inhibitors of metalloproteinases (TIMPs)] is shifted towards excessive degradation, reflected in bronchoalveolar lavage (BAL) as increased MMP concentrations. Because of their critical role in lung homeostasis, MMP activity is tightly regulated, but to what extent this regulation occurs t
The introduction suggests a model for defining and categorising different types of graffiti, and the term TTP (Tags/Throw-ups/Pieces) is presented. Chapter I relates the body of research up to the present day and proposes a comprehensive interpretation, based partly on English and German subculture- and socialisation theories. Chapter 2 presents the social background and internal social pattern o
Detection and removal sentinel lymph nodes (SLN) is important in the diagnosis and treatment of breast cancer and malignant melanoma. The SLN is the first regional lymph node draining the cancer tumor and if the cancer has spread it is most likely to find cancer cells in the SLN. In this study we have been able to detect multimodal superparamagnetic iron oxide nanoparticles (SPIO-NP) in rat SLNs i
During the past decade, production of products has increasingly been relocated to countries outside the western industrialised area, while consumption of the same products in the west has increased to a considerable extent. Implementation of national policies for limiting the environmental and health impacts of production has encountered a number of difficulties as a result. Policy instruments, no
Isolated exposures of basalt in a 1000 km 2 area in the central northern part of Skane have long been known to the local people. A volcanic origin for these rocks was finally resolved by geologists during the early 1800s. Until 1965 the volcanic activity was considered to have occurred during the Cenozoic i.e. not older than 65 Ma. In the 1970s attempts were made to directly date the volcanic acti
Background: In obese patients, jejunoileal bypass (JIB) has been used to induce weight reduction. Changes in the neuroendocrine system may be affected by the JIB-operation, because the proximal small intestinal mucosa has a rich supply of endocrine cells and peptidergic nerves. Materials and Methods: In 37 obese patients operated with JIB 1-30 years ago, small intestinal biopsies were taken at the
BACKGROUND: Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS: Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify eosi
We have investigated the regulation of hormone secretion from rat pancreatic islets by the GABAB receptors (GABABRs). Inclusion of the specific GABABR antagonist CGP 55845 in the extracellular medium increased glucose-stimulated insulin secretion 1.6-fold but did not affect the release of glucagon and somatostatin. Conversely, addition of the GABABR agonist baclofen inhibited glucose-stimulated in
Bioelectrocatalytic reduction of H2O2 catalysed by lignin peroxidase from Phanerochaete chrysosporium (LiP) was studied with LiP-modified graphite electrodes to elucidate the ability of UP to electro-enzymatically oxidise phenols, catechols, as well as veratryl alcohol (VA) and some other high-redox-potential lignin model compounds (LMC). Flow-through amperometric experiments performed at +0.1 V v
Leaching of dissolved organic carbon (DOC) from the forest floor and transport in soil solution into the mineral soil are important for carbon cycling in boreal forest ecosystems. We examined DOC concentrations in bulk deposition, throughfall and in soil solutions collected under the O and B horizons in three Norway spruce stands along a climatic gradient in Sweden. Mean annual temperature for the
