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.

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.

In Peter Weiss debut Fra?n o? till o? (1947) the ?I? travels from island to island as a castaway. The island here can signify, or work as a synecdoche for exile and the feeling of isolation that exile often induces. But the movement from island to island also implies a restless state: Peter Weiss shifting from painting to writing to filmmaking and theatre, from German to Swedish and then back to German. The years during exile and the years that followed the exile until his breakthrough in Germany with Schatten des ko?rpers des Ku?tchens (1960), Abschied von den Eltern (1961) and Fluchtpunkt (1962), were the formative years of Peter Weiss authorship.

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.

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.

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.

Cancer is one of the most common diseases and it affects not only adults but also many adolecents and children every year. Those who are affected of disease face many challenges that will affect their lives. The aim of this literature review was to illuminate adolecents experience of cancer and how it affects them in their daily living. The result showed that the adolecents experience many physical and mental side-effects from disease and treatment. They expressed the need of information, support and understanding from their families, friends, school and care givers.

This literature study assembles current knowledge about CODD (Contagious Ovine Digital Dermatitis). The aetiology of this disease is not completely known and to obtain a manageable overview, this study aims to summarize the knowledge from published studies and shed light on the subject. Search for literature on the subject has been made in the Web of Knowledge, PubMed and Google Scholar, and has been compiled in this paper. Footrot and ovine interdigital dermatitis are differential diagnosis of CODD and they possibly have a common role in the emergence of CODD. Several studies have drawn parallels to bovine digital dermatitis.

Since long, Sweden has had exceptionally low calf mortality compared to most other countries. The tradition has been to keep calves in individual pens. With increasing number of cows per herd there is now a larger interest in more efficient and economical group systems for housing calves. However it has been noticed that bigger herds have more health problems and higher calf mortality than smaller herds. The early signs of disease are harder to detect when the animals are not fed manually.

Vid Masugn 3, SSAB Tunnplåt AB i Luleå, pågår arbete för att vidareförbättra råjärnets kvalitet genom minskad variation av Si och för att ytterligare minska förbrukningen av reduktionsmedel. För att få en ökad kunskap om tillståndet i den nedre delen av Masugn 3 utfördes i april 2004 en koksborrning ur tre av masugnens 32 formor. Försöken ingår i ett forskningsprojekt inom Jernkontorets forskningsprogram. Syftet med examensarbetet var att karaktärisera raceway och den döde mannen genom att studera borrkärnorna, processdata, koks från forma provtagen genom koksrakning, manuell mätning av racewaydjup och racewaydjupsmätning med radiometrisk utrustning. Till sist undersöktes bottentemperaturen tillsammans med andra parametrar, såsom råjärns- och slagganalyser och råjärnstemperatur, för att fastslå om den döde mannen var aktiv eller inaktiv.

AbstractThe Northern Wheatear (Oenanthe oenanthe) is a small insectivorous passerine bird living in open landscapes. Both parents feed the brood of approximately five chicks, but little is known about how each sex allocates their feeding effort. In this study I investigate feeding nest visit differences between male and female Northern Wheatears relative to the age of the chicks, the number of chicks and the quality of the territory for 17 pairs from 2008-2010. Data were collected using automated data loggers to record nest visitation rates during chick feeding, and the sex was determined from nest video cameras. I also examine if the parents? rate of feeding visits changes over the nestling period.

This paper shortly describes the coronavirus family, bovine corona viruses (BCV) properties and two diseases that BCV causes, winter dysentery and calf diarrhoea. The purpose of the study was to compare different diagnostic methods to detect BCV. Different methods are discussed, PCR, ELISA, immunofluorescense and virus isolation. Investigations were made in three different herds with winter dysentery; one dairy cattle farm with about 100 cows of different ages, one testing station for bulls with about 150 bulls and another small dairy cattle farm with 26 cows and 20 replacement heifers and calves. Faeces and nasal swabs were analysed with PCR and ELISA. The result shows that PCR seems to be a reliable method for detecting BCV but that the ELISA test can not be used as a reliable diagnostic method to analyse samples from animals with winter dysentery..
