Evaluation of ELISA and rapid test for the analysis of fecal Calprotectin
ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.
Avel för bättre kalvningsegenskaper hos mjölkkor
Kalvningssvårigheter och dödföddhet är problem som finns hos svenska mjölkkor och som ökat under de senaste åren, speciellt bland förstagångskalvare. Problemen försämrar kornas välfärd och kostar pengar för bonden. Flera studier har gjorts för att kartlägga så kallade quantitative trait loci (QTL) kopplade till kalvningsegenskaper och många kromosomregioner har hittats som kan innehålla gener som påverkar dessa egenskaper. En viss oenighet finns i resultaten från studierna, men flera studier har hittat QTL kopplat till kalvningsegenskaper på kromosom 4, 6, 7, 10 och 18. Sverige har inkluderat kalvningssvårigheter i det traditionella avelsprogrammet sedan 1995 men inga större genetiska framsteg har gjorts.
A targeted evaluation of OpenEye?s methods for virtual ligand screens and docking
The process of drug discovery is very slow and expensive. There is a need for reliable in silico methods; however the performance of these methods differs.This work presents a targeted study on how the drug discovery methods used in OpenEye?s tools ROCS, EON and FRED perform on targets with small ligands. It was examined if 12 compounds (markers) somewhat similar to AMP could be detected by ROCS in a random data set comprised of 1000 compounds. It was also examined if EON could find any electrostatic similarities between the queries and the markers.
Kan en avreglerad sjukförsäkringsmarknad ge oss den sjukförsäkring politiker vill att vi ska ha?
Hög sjukfrånvaro är en ständigt aktuell fråga i Sverige. Förutom problemet med hög sjukfrånvaro i absoluta tal finns i Sverige även stora regionala skillnader i sjukfrånvaro som inte kan förklaras med skillnader i hälsostatus mellan olika regioner. För att sjukförsäkringen ska få mer karaktär av försäkring med mindre godtycklighet i ersättningsbedömning krävs en tydligare koppling mellan risken som ska försäkras bort och försäkringens användande. Frågan som behandlas i denna uppsats är huruvida sjukförsäkringens uppgift att hantera risk för inkomstbortfall på grund av ohälsa samt att omfördela resurser mellan högrisk ? och lågriskindivider kan utföras mer effektivt och försäkringsmässigt på en konkurrensmarknad än med en enhetlig sjukförsäkring.
Smärtskattning vid bröstsmärta en kombinerad empirisk och litteraturstudie inom prehospital sjukvård
Aim: The aim of this study was to investigate how VAS (Visual Analogue Scale) is used in the prehospital environment, and describe how patients 40 years and older with acute chest pain describe their pain with help of VAS. Further, to investigate how the literature describes other instruments to evaluate pain. Method: This was a descriptive study and used both literature and empiric material as foundation. The selection consist of the paramedics medical record from one emergency department, 100 men and 100 women with chest pain witch had been transported with ambulance to one hospital in middle of Sweden. A literature review was done in order to see what previous research recommends for pain rating scales.Results: The study showed that 71 (35 %) of 200 individuals pain were rated with VAS according to the guidelines for the ambulance department.
Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Utvärdering av digital flygbildstolkning & automatisk beståndsindelning för det praktiska skogsbruket :
To be able to plan different treatments, accurate data is required. The collection of data is often expensive and that?s why the aim is to lower the inventory costs without loosing the accuracy of the data. Holmen Skog has in its strive to lower the costs, decided to evaluate two different methods for forest delineation, computer aided forest delineation and digital stereo view. This study?s purpose is to evaluate these two methods in regard to usability for a beginner and how good the delineation gets.
En analys av Hosni Mubaraks sista tal som Egyptens president
On the 10th of February 2011 Hosni Mubarak gave his last speech as the president of Egypt, on the following day he resigned the presidency after more then two weeks of violent protests against his rule, and with that his 30-year long rule over Egypt had come to an end. This bachelor thesis aims towards examining this speech using both qualitative and quantitative research methods in order to reach a useful analysis of the speech. The conclusions of this thesis is that several methods were used in the speech in order to win the listeners acceptance and approval for the speaker, and then to use these in order to soothe, or preferably to completely stop, the current revolution. The methods that have been found to play major roles in achieving this are; portraying the speaker, defining the listener, promises of improvements and of justice/revenge, and nationalism. This thesis is written in Swedish with Arabic excerpts..
Optimala strategier för whist
Whist is one of the most played card games of the world. Though there have been many studies made in the field of game theory, whist is still somewhat of an unchartered territory. In this thesis some methods to obtain an optimal strategy for whist are discussed. Whist belongs to a group of games called logical games. For this group there exists algorithms which result in an optimal strategy.
Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :
This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality.
In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.
