Genetiska studier på fågelinfluensa :
In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.
Price transmission dynamics of Chinese ADRs listed on the NYSE
Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.
Inokulmmängdens betydelse för utveckling av vetets stråbasröta orsakad Fusarium graminearum : utvärdering av ett biotest
Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.
Hund som komparativ modell för autoimmuna sjukdomar :
In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review.
Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.
Hypoadrenokorticism hos storpudel :
Hypoadrenocorticism (Addison´s disease) results from insufficient production of glucocorticoid and mineralcorticoid hormones from the adrenal glands. The disease is often difficult to diagnose in an early stage because of the multitude of associated vague clinical signs. The standard poodle is one breed presupposed to be at higher risk of developing the disease. The purpose of this study was to give a review of canine hypoadrenocorticism as described in literature, and to characterise Addison´s disease in a population of standard poodles in Sweden. Statistics on incidenceproportions by breed for hypoadrenocorticism from the database of the Swedish insurance company Agria are presented.
Histiocytära sjukdomar hos Berner Sennenhund :
The histiocytic diseases are generally rare in dogs and not much is known about
the disease. The disease complex that includes both a reactive form and a tumour
form, is however common in certain breeds, among them the Bernese Mountain
Dog. As the literature is very limited on the subject of histiocytic diseases, my aim
with this thesis has been to gather current knowledge of these diseases. I have also
attempted to estimate the frequency of the diseases among the Swedish Bernese
Mountain Dogs and investigate if they appear to be more common among certain
families..
Lungfibros hos hund : fallbeskrivningar, histopatologi samt analys av surfaktantproteiner
Idiopathic pulmonary fibrosis (IPF) is a chronic respiratory disease with an
estimated incidence of 3-6 cases per 100 000 inhabitants in Sweden. There is no
cure for the disease, which inevitably leads to death. A similar disease has been
found among terrier dogs, with an especially high prevalence in the West
Highland White Terrier (WHWT). Dogs with pulmonary fibrosis become
lethargic with exercise intolerance, and in some cases they develop cough and
respiratory distress. This thesis gives a brief review of the field of pulmonary
fibrosis and presents a method for analyzing surfactant proteins in
bronchoalveolar lavage (BAL) in the dog.
Reproduktion och reproduktionsproblem hos taxtikar
Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of Disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).
Tollarsjuka hos hund : en retrospektiv studie med journalsammanställning av 18 hundar
?Tollarsjuka? is a disease with a suspected immunopathological background seen in Nova Scotia duck tolling retrievers. Pyrexia, lameness, stiffness and joint- or musclepain are typical clinical signs.
The purpose of this study is to describe case histories from dogs with a possible evidence of ?tollarsjuka?. 18 private dogs were included in this report.
Generalised stiffness, lameness and fatigue were the most frequent manifestations of the disease.
Förekomst av Giardia i symtomfria valpkullar :
The flagellate Giardia intestinalis has been known to cause diarrhea in both man and
dog. Results from epidemiological studies have indicated that transmission of the
parasite from dog to man is plausible even though that route of infection has yet to be
shown. Several international studies have shown that the parasite frequently occurs in
asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not
known though. In this study, faecal samples were collected at two separate occasions
from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract.
The samples from each litter were pooled but the samples from the bitches were
analyzed individually.
Upplevelser av att leva med övervikt : En systematisklitteraturstudie
Background: Schizophrenia is a serious disease with potential to implicate consequences on both the family and the sick. Nurses have a fundamental responsibility to relieve suffering, and also to offer support to both the individual and the family.Aim: To illuminate experiences of being a family member to a person with schizophrenia.Method: A systematic literature review was chosen. Nine articles were included. After having analyzed the results six categories were found.Result: The family members experienced the disease as fluctuating and stressful. Some felt ashamed for their sick family member and withdrew from the rest of the society.

Partikelmängd i traktorers hydrauliksystem : en jämförande studie av två traktormärken med skilda respektive gemensamma oljor i hydraulik och transmission
Det finns studier som visar att skador i transmission och hydraulik är bland de vanligaste och dyraste skadorna på traktorer. Ytterligare studier visar att det finns mycket partiklar i oljorna hos lantbrukets traktorer. Även om inte partikelmängden som sådan är orsak till skadan kan den orsaka följdskador, ofta med stora kostnader som konsekvens.
Partiklarna kan komma från både inre och yttre källor. Partiklar som uppstår i traktorn uppkommer på grund av olika slitage på materialen i traktorn. Partiklar som kommer utifrån och genom yttre faktorer kommer från till exempel luftningen på hydrauliksystem eller från slarv vid påfyllning av olja.
Genotype by environment interactions of claw health in Swedish dairy cattle in tie stalls and loose-housing
Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.
Hur upplever kvinnor med fibromyalgi sin livssituation? - en litteraturstudie
Background: Fibromyalgia is a psychosomatic disease that emerges without any known cause. For a long time, it has been believed to be a part of the menopause. Between 0,7 and 4,8 % of the women in Scandinavia are diagnosed. The most obvious symptom is pain. Aim: The aim with the literature review was to describe how women with fibromyalgia experience their lifesituation.
