Effects of treatment with PiNO (Pulsed Inhaled Nitric-Oxide) on the metabolism in colic horses undergoing abdominal surgery.

The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.

Jämförelse av resultat mellan manuell gelkortsanalys och automatisk immunohematologisk gelkortsanalys vid utförande av blodgruppskontroll och antikroppsscreening (BAS-test)

Incompatibility between donors and recipients can cause fatal hemolytic transfusion reactions (HTR), kidney damage and death and immunization of the recipient. Antigens on the surface of erythrocytes in the ABO blood group system and regular natural antibodies against these in the patient?s plasma must be considered. An individual always has a corresponding antibody of IgM in their plasma. Irregular antibodies acquired by transfusion or pregnancy and active in body temperature also cause the HTR incompatibility.

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.

El Niño Southern Oscillation och dess atmosfäriska fjärrpåverkan.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

The purpose of this bachelor's thesis is to examine how public libraries in Sweden handles their weeding procedures. A series of questions are asked: How does libraries in Sweden motivate weeding? What principles constitutes the procedure of weeding? Which aspects are given most importance when weeding is decided. How does views on weeding differ between libraries of different sizes? How does longer or shorter professional experience influence the view on weeding? The study was done through an online questionnaire which was sent to a number of staff members on different libraries via e-mail.

Kokosfetts påverkan på blodfetterna ? En systematisk översiktsartikel

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Coconut fat?s effect on blood lipids - A systematic overviewAuthor: Linnéa Hult and Sandra WestlingSupervisor: Fredrik BertzExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2013-04-11Background: Coconut fat has recently been praised in the media. Amongst other things,coconut oil has been said to lower cholesterol (1, 2). This despite the fact that coconut oilcontains of 92 % saturated fat, which strong scientific evidence support raises the blood lipidsand thus increases the risk of cardiovascular disease (3).Objective: To examine the scientific evidence for how blood lipids in adults are affected byan intake of coconut fat compared to an intake of other kind of fats.Search strategy: PubMed and Scopus have been used in the literary search. Keywords usedwere "coconut fat", "coconut oil", "plasma lipids" and cholesterol [MeSH].Selection criteria: Human studies of RCT or cohort type, published since 1983.

Seroprevalence of Rift Valley fever in sheep and goats in Zambezia, Mozambique and preparations for a metagenomic study of arboviruses in ticks

The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-epidemic/epizootic periods. The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.

The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Att mäta ankeltryck i primärvården : Distriktssköterskors och distriktsläkares uppfattningar om en undersökningsmetod och dess användning

Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.

När en roman blir teveserie: Om Jane Austens aktualisering i och med 1995 års teveinspelning av Pride and Prejudice

The aim of this Masters thesis is to examine how Jane Austens Pride and Prejudice, first published in 1813, was established in different literary orbits after the transformation to the television medium in 1995. I also want to find out what this adaptation meant for the popularity of Jane Austen, the circulation of her works and the rebirth of her authorship. It has furthermore been of interest to discuss the reasons why Jane Austen and her works became so popular. Questions posed in the study are: What has the 1995 production of Pride and Prejudice meant for the spreading of Jane Austens literary work and for the rebirth of her authorship? How has Pride and Prejudice moved between the literary orbits after it became a television-serial in 1995? Why did the circulation get the character it got in the 1990s? In order to find feasible answers to these questions I have used Hans Hertels model of the five literary orbits as theoretical starting point.

When and what determines the death of an animal? A study investigating the heart activity during slaughter of farm animals

Slaughter of animals should consist of two steps in order to be considered humane. The first step of the slaughter process is stunning, with the purpose of inducing unconsciousness and insensibility in the animal. The second step is exsanguination, which causes bleeding and eventually death. What death really means in these situations has been discussed intensively, but still no agreed definition has been accepted. Nonetheless, it is conceded that animals are declared dead when consciousness is irreversibly lost, and absence of respiration and Blood circulation are observed.

Stabilitetsberäkningar och åtgärdsförslag vid islast på Skålandammen

Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.
