Canine S- and M/L- cone electroretinograms
Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989).
Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).
Fysiska boendemiljöns utformning för främjande av aktivitetsutförandet i dagliga aktiviteter hos personer med demenssjukdom: en litteraturöversikt
Syftet med denna studie var att genom en litteraturöversikt beskriva olika sätt att förändra den fysiska boendemiljön för att främja aktivitetsutförandet i dagliga aktiviteter hos personer med demenssjukdom. Litteratursökningen genomfördes i databaser samt manuellt i referenslistor. Analysen av de 16 valda artiklarna genomfördes med en kvalitativ analysmetod och resultatet presenterades i tre kategorier: ?Att känna igen?, ?Att arrangera? samt ?Att förtydliga?. Resultaten av studien tyder på att en mer hemlik och familjär miljö, arrangemang av rum och föremål så att överblickbarhet medges samt förtydligande av boendemiljön genom till exempel skyltar och färgkontraster främjar aktivitetsutförandet.

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar
The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

Sahlgrenska AcademyAt University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstract:Titel: Effect on muscle building associated with alcohol intake after exerciseAuthor: Frida Bond och Linnea DanielssonSupervisor: Frode SlindeExamminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDatum: May 26, 2014Background: Drinking alcohol is often used as something to spice up weekdays as well as more festive occasions. The reverse aspect of alcohol consumption is that the body sees alcohol as toxic and therefore the basis for a number of diseases. Exercise and physical activity have been proven to be good for several welfare diseases such as diabetes and cardiovascular disease. Among people in general, opinion is divided as to how exercise combined with alcohol affects muscle building, but what do science say? Objective: The purpose of this review article is to analyze and summarize the existing scientific data about how the structure of muscles is affected in relation to alcohol intake after exercise.
Visualisering och beräkning av hudkapillärer
The aim of this thesis was to develop an objective and automatic method for identifying capillaries in microscope images of the skin. Furthermore, statistical data about the identified capillaries and the capillary distribution should be computed and stored in a database. The method was implemented using the platform independent programming language Java. An analysis of microscope improvement using various polarization filter setups and wavelength filtershas also been performed, as well as a pilot study of the effect of applying a local anaesthetic cream on the skin. The method is developed and aimed at research on various pathological skin conditions affecting the capillary distribution.
BCAA-supplementering i samband med levercancerkirurgi
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: BCAA supplementation in patients undergoing resection for liver cancerAuthor: Mikael Semaan and Viktor SjölingSupervisor: Fredrik BertzExaminer: Frode SlindeProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013BackgroundLiver cancer is the fifth most common cancer worldwide and the third largest to cause death. Protein-energy malnutrition is common in patients with liver disease and they often suffer from changes in the hepatic metabolism of nutrients and other substances. There is a basis for recommending BCAA supplementation in other certain liver diseases. Given the similar clinical picture of liver cancer surgery, it is possible that supplementation of BCAA can be beneficial for these patients as well.ObjectiveThe aim was to study the scientific basis for the effect of branched chain amino acid (BCAA) supplementation in liver cancer patients. Can it improve their recovery in terms of nutritional status and albumin levels, and does it changes the duration of hospital stay, after surgery?Search strategyFive extensive searches were performed on PubMed and Cochrane after appropriate study material.
De dolda sjukdomarna : osteoporos och artros kvarteret Banken 1 i Visby
This Bachelor paper deals with skeletal diseases like osteoporosis and osteoarthritis. 24 medieval individuals from the block Banken 1 in Visby, Gotland were chosen for an osteological analysis. Osteoporosis affects the bone with low bone mineral density and can lead to possible fractures and Osteoarthritis is a degenerative joint disease. A DEXA reading was done at Dr. Roland Alvarssons Doctorial practice in Visby and the results from the DEXA reading showed that none of the individuals suffered from osteoporosis, but one suffered from osteopenia.
?Det är ju en naturlig del? : De anställdas känslor inför och arbete med uttryck för onani på gruppboenden för personer med utvecklingsstörning
The aim of this study was to investigate the emotions among the staff at the group housings when they observe the caretakers expressions of masturbation and how the staff handles these expressions in their daily and long-term work. The theoretical concepts that were used in this study are group housing as a public and private arena, occupational role, relation, humanistic effort, pedagogical effort, empowerment, care ethic and emotions. The concepts are related to each other and constitutes the foundation for the analysis of the empirical data used in this study. A qualitative study was carried out, in forms of half structured interviews with six informants, of which the majority was women. It came to light that the interviewees only had positive feelings for the caretaker?s expressions of masturbation.

METHOD: A qualitative approach was used and the date was semi-structured interviews with open-ended questions.
Estimation of heterosis and performance of crossbred Swedish dairy cows
The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases.
Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.
Use of feline TK1 as a biomarker in disease monitoring
Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis.
TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.
