Inclusion Body Disease hos boa- och pytonorm : diagnostiska metoder
Inclusion body disease (IBD) affecting boas and pythons is a serious and common disease. Boas can be clinically healthy carriers, which makes control of the disease difficult. The causative agent has not yet been confidently identified, and therefore there are no serodiagnostic tests available. Today, histopathologic examination of tissue biopsies is the recommended antemortem diagnostic method, but there are several disadvantages. The objective of this study was to compare the sensitivity of two diagnostic methods ? liver biopsies and blood smears, and to evaluate ultrasoundguided needle biopsy of the liver.
The possible role of transmissible gastroenteritis virus (TGE) and porcine respiratory corona virus (PRCV) in the mortality of Ugandan back-yard piglets
In Uganda, small scale pig production plays a major role for households to earn a living and to secure their access to meat. Piglet mortality due to diar-rhoea-related dieseases is high. In an attempt to understand the underlying causes for this high mortality this study aims to investigate the role of trans-missible gastroenteritis virus (TGEV) and is a part of a larger project con-ducted at Makerere university in Uganda.
A complicating factor in this investigation is the porcine respiratory corona-virus (PRCV), a stabile mutant form of the TGE virus. The occurrence of this virus had shown to alter the impact of TGEV in e.g. Europe and North Amer-ica.
Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.
Early immune responses to an adjuvant (AbISCO-100) tested in porcine peripheral blood mononuclear cell
Immune stimulating complex (iscom) matrix is a formulation that is used as anadjuvant within research. The capability of the iscom matrix to elicit an immuneresponse when not present together with an antigen has not been extensivelyinvestigated. One way to evaluate the status of the immune system is to measure theamount of cytokines that usually are produced by various cell types during an immuneresponse. The aim of the present study was to evaluate the early immune responses inporcine peripheral blood mononuclear cells (PBMC) after stimulation in vitro with theiscom matrix, AbISCO®-100. The immune response was evaluated by measuring themRNA expression for various cytokines, a chemokine receptor (CXCR4) andregulator of G-protein signaling (RGS16) in porcine PBMC after stimulation withAbISCO®-100 or other inducers like a lipopolysaccharide (LPS) and a CpGoligodeoxynucleotide (ODN 2216) used as controls.
Etiologi för sporadisk hepatit E i industriländer
Det finns många olika typer av bromerade flamskyddsmedel. De är alla stabila i miljön men graden av toxicitet och bioackumulering varierar. Att bromerade flamskyddsmedel är
endokrinstörande är känt men min hypotes är att de även är neurotoxiska och att de kan orsaka neurologiska störningar hos människa.
Människor exponeras för bromerade flamskyddsmedel via damm och föda. Barn och foster som är känsligare än vuxna kan även exponeras via modersmjölk respektive placenta. Barn
har högre serumkoncentrationer av bromerade flamskyddsmedel än vuxna.
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.
Perfluoroalkyl substances in Arctic birds : a comparison between glaucous gulls and black guillemots from Svalbard
Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.
Studier av alkaliskt fosfatas och kollagen samt deras betydelse för skelettets mineralisering
There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.
Tungmetaller i metabolismen hos värphöns och slaktkycklingar
Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.
Spelar tarmcellernas interna fettförbränning en roll i regleringen av födointag?
Since several lifestyle diseases are associated with obesity much research is carried out within the area. Researchers have found that oxidation of fatty acids within the body?s cells may give rise to peripheral signals which regulate food intake, but it is still unclear where such a mechanism takes place. Although much evidence suggests that it is the hepatocytes in the liver that send signals regulating food intake, some researchers have begun to question this theory. Instead they argue that the mechanism takes place within the enterocytes since they are well localised in the gut for such assignment.
African swine fever in Uganda : description of a recent outbreak and possible differential diagnoses
This study had two different aims. The main aim was to investigate the dynamics and impact of African swine fever (ASF) on a farm in Uganda during a recent outbreak through a case study. The second aim was to estimate the presence of two important differential diagnoses of ASF: Classical swine fever (CSF) and Porcine Reproduction and Respiratory syndrome (PRRS).The field and laboratory based case study of the farm level dynamics of ASF virus during a recent outbreak (October-December 2010) on a farm in the district of Mityana, Uganda, was conducted, using interviews, ELISA and RT-PCR. The financial impact on the farm was also estimated. The impact of the outbreak was profound.

Syfte: Syftet med studien är att beskriva patientens upplevelser och livskvalitet i väntan på en levertransplantation. Metod: En litteraturöversikt valdes där 9 vetenskapliga artiklar granskades och analyserades enligt Fribergs modell (2006). Resultat: Beskedet om att bli uppsatt på väntelista präglades av både positiva och negativa känslor; glädje, lättnad, oro samt tveksamhet.
Förekomst av Helicobacter spp. hos hund : samband med hepatit/pankreatit?
To date, the genus Helicobacter consist of 26 different species and even more species are yet to be characterized. Helicobacter has been detected in connection with diseases in the liver and pancreas in humans and animals.
Helicobacter spp. are gram negative, curved, S-shaped or spiral shaped bacteria. They are microaerophilic and have flagella that make them motile. Helicobacter, present in the gastric mucosa neutralize the gastric acid through production of urease that hydrolyses urea to ammonia and bicarbonate.
The pig as an animal model for type 1 Diabetes Mellitus ? with focus on carbohydrate and fat metabolism
Diabetes mellitus is an endocrine disorder affecting a range of different mammals, including dogs, cats, horses and humans. Worldwide, 347 million people have diabetes, and the disease is an increasing burden on the world?s poorest countries. The disease is characterised by chronic hyperglycaemia and afflicted individuals experience increased thirst, polyuria and weight loss, sometimes despite increased appetite. Diabetes mellitus is either insulin dependent or non-insulin dependent.
Fumonisin B1 : toxiska effekter och verkningsmekanismer för toxicitet
Mykotoxinet fumonisin B1 som förekommer i hela världen på framförallt majs, har visats ge upphov till flera olika toxiska effekter hos en mängd olika djurslag. De mest specifika är leukoencefalomalaci hos häst (ELEM) och lungödem hos gris (PPE), men även skador i lever, njurar och hjärt-kärlsystemet samt carcinogenicitet har observerats. Effekterna skiljer sig en hel del mellan olika djurslag, vilket den här uppsatsen syftade att hitta möjliga anledningar till. Dessutom var syftet att sammanställa information om fumonisins verkningsmekanismer ? både bekräftade och mer osäkra sådana, samt beskriva de toxiska effekterna hos olika djur och i olika organ och även ta upp diagnosticering, vilken dos som krävs för att orsaka sjukdom samt jämföra de rekommenderade gränsvärden som har satts upp för fumonisiner i foder med forskningsresultat.
