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.

Det förändrade underlivet : En undersökning om kosmetisk intimkirurgi borde omfattas av lagen mot könsstympning

The swedish law against female genital mutilation (FGM) prohibits procedures that removes parts of the female genitalia and thereby makes permanent changes in the body. The problem with the wording of the law is that it may also apply to the western phenomenon cosmetic genital surgery. This paper therefore examines if cosmetic genital surgery should be covered by the swedish law against FGM, by making a critical comparing analysis. The paper begins with comparing FGM with cosmetic genital surgery to prove that there are more similarities than differences between the procedures. By using the theoretical perspectives universalism and postcolonialism, the paper then examines why, particularly in the West, there is a different approach to FGM than to cosmetic genital surgery, regardless of the similarities of the procedures.

Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

Traditionella institutioner i Afrika - Ett hot mot den moderna staten?

The function of traditional leaders in the modern states of Africa has been under debate for decades. The dominant research discourse suggests that these institutions should be integrated into the state in order to minimize the amount of parallel political spheres, since the latters are considered to affect state legitimacy negatively. But are the states in a situation where they need to compete with the traditional institutions in order to gain more legitimacy? If so, is the struggle for legitimacy a zero-sum game where there can only be one winner? Or is it possible for these institutions to co-exist or even benefit from each other? The aim of this bachelor?s thesis is to research if, and to what extent, African citizens? confidence in traditional institutions has an effect on state legitimacy. This has been done by statistically analyzing the data from the latest completed round of the Afrobarometer survey, a study that has been conducted in 20 different countries across West- and Northeast Africa.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Den gömda kyrkklockan : en studie om en kyrkklockas sägen

There is a legend about a church on the island of Orust in the small village of Tegneby. The legend tells a story about a hidden church bell in the mysterious hole in the creek.?During a war long time ago, people were afraid that the King Gustav Vasa would take their church bell to use as material for cannons. So the people in Tegneby hid their beloved church bell in a hole in the creek below the church and there it remained for seven years?  (main legend)The aim of this paper was to find out if this legend still is alive in the area of Tegneby.

Vårtor på mjölkkornas spenar :

The reason why I choose the subject ?Warts on teats of Dairy Cows? was because the herd I work with has big problems with skin-complaint on teats and udder. So I found it interesting to try to find the reason why the cows look like they do and even to find a way to relieve the trouble. The examine work included both a literature research, an experimental test, concerning a comparison of different teat sprays and also an inquiry-research about the occurrence of warts in practical herds in order to collect as much facts as possible. Three companies, selling different types of teat disinfectants, were willing to sponsor the teat dipping experiment. The aim of the experiment was to see if any special disinfectant had more pronounced healing effects on teat warts. The date for the experiment was 18th December 2004 to 22nd January 2005, which was going to be 5 weeks.The experiment was carried out in the herd of Ola and Eskil Carlsson in Fjärlöv, Hässleholm. The three compared teat spray chemicals were; Nova Viri Sun, Nardosept, and BlockadeTM. These chemicals were compared to one control group, which teats were treated with the ordinary chemical normally used in the herd, i.e.

Rotavirus zoonotiska potential : kan infekterade föl smitta människa?

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Det postkoloniala resandet i Egypten : En diskursanalys av resebroschyrer

During the colonial period Europeans travelled to Egypt. The French had explored Egypt through the mapping and this was published in a collection of books called Déscription de l?Égypte. Exhibitions and publications like Déscription de l?Égypte, which aimed at giving a view of Egypt, raised public interest for journeys to the Orient.

Den demokratiska antipatrioten och den rasande förtryckaren: En diskursanalys av representationen av svenska och icke-svenska aktörer i historiska läroböcker

This study analyzes the discursive content of four history textbooks in order to demonstrate how national identities are formed and how they differ from each other. This was done through discourse analysis guided by social constructivism and John M. Hobson?s dichotomy of East and West. The study shows that textbooks mainly construct national identities in three ways; first by making a clear distinction between ?The Self? and ?The Other?, second by preserving a world order based on the notions of the invariant hegemony of the nation-state, and third by utilizing stereotype based dissimilarities in order to accentuate existing differences between nationalities. Implicit ideals and values in the historical discourse play an important part in the construction of identities; however sends a contradictory and ambiguous message.

Behöver man förbättra omhändertagandet av personal som blivit utsatta för stickskador?: En studie av sjuksköterskor och undersköterskor på akutmottagningen och infektionskliniken vid Centralsjukhuset i Kristianstad

Stick- och skärskador utgör den största risken för överföring av blodsmitta i sjukvården. De vanligaste smittämnena är hepatit B-virus, hepatit C-virus och HIV, som kan åstadkomma kronisk sjukdom och t o m vara letala. Därför måste förebyggande arbete för att undvika sådana skador prioriteras. Åtgärder vid tillbud eller skada finns beskrivna i arbetarskyddsstyrelsens regelverk. Riskbedömningar är gjorda för dessa virus och rutiner är utarbetade för upp-följning efter stickskada med provtagning och i vissa fall profylaktisk behandling.

Seroprevalence of Japanese encephalitis virus in pigs and dogs in the Mekong Delta

Japanese encephalitis virus (JEV) is one of the leading causes of acute encephalitis in humans. The virus is spread by mosquitoes, mainly belonging to the Culex species. The main reservoirs are considered to be birds and pigs, with pigs constituting the most important reservoir in regard to human infection. During the last few decades the production of pork has increased significantly in Vietnam. With 90% of pigs being kept in households owning 10 pigs or less, pigs are widely spread across most parts of the country.

Dromedarens roll vid spridning av Middle East respiratory syndrome coronavirus

Middle East respiratory syndrome coronavirus (MERS-CoV) är ett virus som först observerades hos en patient år 2012 på ett sjukhus i Saudiarabien. Viruset orsakar luftvägssymptom och ibland gastrointestinala symptom. Dödligheten hos människa är över 30%. Eftersom tidigare erfarenhet har visat att nya coronavirus ofta har sitt ursprung i en djurpopulation har många studier gjorts för att undersöka spridningen av MERS-CoV och förekomsten av en eller flera reservoirer. Denna litteraturstudie har som mål att undersöka vilka bevis det finns för dromedarens roll i smittspridningen av MERS-CoV. Då flera seroepidemiologiska studier gjorts som visar att MERS-CoV eller ett nära besläktat virus har cirkulerat i dromedarpopulationen i över 20 år har man gått vidare och undersökt bl.a.

Ett amerikanskt korståg? En jämförelse mellan katolska kyrkans korståg under medeltiden och USA:s politik under kalla kriget.

The Catholic Church launched several crusades during the medieval ages in order to regainthe holy lands and spread the word of God. Their main enemy, the Muslims had grownstronger and needed to be suppressed. This common enemy united Europe under the banner ofthe Catholic Church. In order to fund these crusades the church turned to the wealthyEuropean kings and lords and asked for funding. In return the kings received an indulgenceletter, and also greater respect from their subjects because of their new appreciation from thepope.
