Development of a real-time RT-PCR for quantification of bovine TLR4 mRNA and evaluation of its use during a BRSV vaccine challenge

The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

Mjölkkors behov av att ligga och att sova

The aim of this literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.

Kodväxling och intersubjektivitet  i tolkmedierade domstolsförhandligar

Reaching shared understanding during court hearings is a prerequisite to ensure a fair trial and maintaining legal certainty. Every month between 2,000 and 3,000 court hearings in Sweden make use of interpreters. Interpreter-mediated conversations involve an extra discourse compared to monolingual conversations which increases the risk of misunderstandings.Using methodology of conversation analysis the study explores how bilingualism is expressed during interpreter-mediated court hearings, at which occasions the Spanish-speaking laymen switch to Swedish and what function the codeswitching fulfills. The study identifies patterns in codeswitching and categorizes them into six different types. Furthermore the ideology of monolingualism in court is challenged and the advantages and disadvantages of codeswitching is discussed.The analysis concludes that even though certain types of codeswitching lead to delays in the conversation, the interaction is mostly favored by the Spanish-speaking party understanding some Swedish.

Proteinkvalitet och biogena aminer i ensilage ? effekt på mjölkkors hälsa & foderintag

The aim of this paper was to explain protein degradation in silage and protein quality and biogenic amines in silage and their effects on the health of the dairy cows. After harvest-ing, the plant proteases degrade the proteins in the plant. The protein degrades to different fractions with different digestibilites in the rumen. Fraction A contains non- protein nitro-gen which is peptides, free amino acids and amines. True protein is in the fraction B and is further divided into three subfractions depending on their solubility.

Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana

In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure. The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.

Blood compatibility of biomaterials made of recombinant spider silk

Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application. When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation. The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions. Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense. Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials. This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating. Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films. Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..

Att finna kärleken @ Internet : en studie om hur kommunikationen mellan åtta par utvecklats från det första mötet online till det första mötet offline

Purpose/aim: The purpose is to get increased knowledge about how the communication had developed from the first contact online to the first meeting in real life and even after when it had turned into a real relationship. I also wanted to know why the eight women I interviewed experienced that the Internet is a good venue to meet and develop a real relationship at and if there existed any differences between those four women who were a bit older and those four women who were young.Material/method: When the purpose with this survey stood clear I decided to use interviews as the method to find out more about my subject. I decided to do eight interviews and I contacted eight women who all found their partners online that were willing to help me and answer my interview questions. I did six of the total eight interviews through MSN Messenger and the other two through the telephone.Main results: I found out that three of the older women had used e-mail and telephone and sometimes SMS communication to find out more about their soon to be partner and after that decided to meet the other person in real life. One of the older women and all four of the younger ones had used a Community and Instant Messenger to communicate with their soon to be partner, they also used the telephone and SMS to communicate with each other but Instant Messenger was the medium that dominated in their wish to communicate.

Escherichia coli-mastitis in dairy cows :

Escherichia (E) coli is one of the most common udder pathogens associated with acute clinical mastitis in Swedish dairy cows. The aim of this study is to review some of the existing literature on E coli mastitis from a Swedish perspective. The bacteria, its most important characteristics, and diagnostics under field conditions is covered, as well as what happens during infection, how E coli affects the cow and which consequences this have. Clinical symptoms associated with E coli mastitis are described and information on when these cases of mastitis usually occurs is given. Risk factors in the cow?s enviroment are described as well as the importance of the cow?s immune defence.

Evaluation of a standardized platelet concentration in samples from platelet concentrates measured over time with impedance aggregometry

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

Vad är Mångfald? : En studie om lärare samt ledning i två skolor i olika delar i

The subject of this paper is to examine the view of diversity among ten teachers and three principals in the Swedish compulsory school. The purpose is to investigate how they relate to the diversity and in what ways it is involved in their work.The French sociologist Pierre Bourdieus basic ideas of habitus, capital and field are used as a theoretical starting point. The study is mainly based on interviews supported by literature in the subject area.The findings show that diversity is associated with ethnicity among all informants. The drawn conclusion is that this is partly due to the mediated picture but also since ethnicity mainly serves as a starting point in the literature..

Språkstimulerande miljöer och metoder - språkstimulering i förskolan

Syftet med min studie är att undersöka ett antal kommunala förskolors språkliga pedagogiska miljöer för att få kunskap om vilka metoder några pedagoger i förskolan arbetar med för att stimulera barns språk- och begreppsutveckling. Jag väljer att lägga fokus på en central frågeställning: Vad menar pedagoger med språkliga pedagogiska miljöer? I ett försök att få svar på mina frågor väljer jag att observera och samtala med yrkesverksamma pedagoger. Resultat visar att pedagogerna betonar att det sociala samspelet har betydelse för barns språk- och begreppsutveckling..
