Ingefäras antiemetiska effekt vid cytostatikarelaterat illamående : En litteraturöversikt
Aim: The aim of this study was to determine whether or not there is evidence for the usage of ginger as an antiemetic in patients experiencing chemotherapy related nausea, based on available scientific literature.Methods: The original articles were found by using search engines PubMed and CINAHL. The selected articles were then analyzed based on their content, quality and results. Based on the results from the content analysis the articles were placed in four different themes.Results: In the first theme two of the articles found that ginger had significant effect on chemotherapy related nausea, when used in combination with regular antiemetic treatment. Two other articles said that it does not. In the second theme four studies found that different forms of ginger lessens nausea, in contrast two other articles found that it does not have any increased effect on said nausea.
Genetisk variation av betydelse för adenosinsignalering vid nydebuterad reumatoid artrit
Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.
Optimization of Lentivirus Production for Cancer Therapy
Vectors based on lentivirus backbones have revolutionized our ability to transfer genesinto many cell types. Lentiviral vectors integrate into the chromatin of target cells and do not transfer any viral genes causing vector replication. Both of these features arecommonly used in gene therapy and have been used clinically in individuals sufferingfrom cancer, infections and genetic diseases. It has been discovered that T-cells can be genetically modified to be used as effective weapons against cancer: therefore virus mustbe produced to deliver the gene of interest into the T-cells. In this project, lentiviralvectors have been produced to transfer the gene coding for a chimeric antigen receptor(CAR) which is directed to CD19 on B-cells.
Proliferativ enteropati hos gris : patogenes och patologiska förändringar
Proliferative enteropathy is a group of disease conditions in pigs where the disease may vary from subclinical to critical with bloody loose feces. The etiological agent is the obligate intracellular bacteria Lawsonia intracellularis. L. intracellularis infects enterocytes from jejunum to colon. The bacteria is taken into cells and start to replicate and cause a massive proliferation of immature enterocytes.
Trastuzumab som adjuvant behandling avbröstcancerpatienter med HER2-positivitet : Hur effektivt är det?
Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.

LigandTracer® och teknologin bakom den har studerats för att hitta de främsta styrkorna samt utvecklingsområden i jämförelse med andra detektionstekniker. Dessa tekniker är surface plasmon resonance, BioLayer Interferometry, quartz crystal microbalance samt surface acoustic wave. Främsta styrkan hos detektion med LigandTracer® är att stor mängd data som beskriver interaktionerna erhålls.
Gener som påverkar pälsens utseende och hälsan hos hästrasen American curly
American curly hästar har lockig päls och drabbas i vissa fall av hypotrikos vilket innebär håravfall. Många tappar förutom pälsen även manen och svansen när de fäller. Lockig päls förekommer även hos katt, hund, mus och tamråtta samt extremt lockigt eller ulligt hår hos människor. Flera av dessa är även drabbade av hypotrikos. Syftet med denna studie är att studera vilka gener som troligtvis styr utseendet och hälsan hos american curly.

Betydelsen av interleukin 4 receptorn (IL-4R) i stimulering av lymfom- och leukemiceller
Cytokiner eller interleukiner är signalpeptider med låg molekylär vikt som
reglerar många viktiga funktioner. De kan delas in i två grupper beroende på deras
effekt på celler. Interleukin 4 (IL-4) till exempel kan tillhöra gruppen
tillväxtfaktorer medan interleukin 6 (IL-6) kan tillhöra gruppen aktiverings- eller
differentieringsfaktorer. IgM-receptorn eller B-cellsreceptorn, BCR, finns på Bceller
och är membranbundna immunoglobuliner (mIg) som har två
huvuduppgifter; att förmedla signaler som styr B-cellens utveckling samt att binda
in antigen som sedan ska presenteras för T-celler. I studien aktiverades B-celler
med antikropp mot IgM (anti-IgM) samt rekombinant IL-4.
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.
Utvärdering av autologt konditionerat serum :
Joint injury (inflammation) or osteoarthritis is the most common cause of poor performance in the athletic horse. Osteoarthritis is the ensuing degeneration of joint cartilage due to inflammation/injury. The single most important factor in the inflammation cascade of joint injuries is interleukin-1 (IL-1). Until recently, these injuries have been treated with products like hyaluronic acid, cortisone and polysulphated glycosaminoglycans (PSGAG).
Several studies have not been able to demonstrate a significant difference in the clinical improvement of joint injuries treated with hyaluronic acid or PSGAG and saline.

4-1BB is up-regulated in human mast cells, when exposed to tumor conditioned medium
Mast cells have for a long time been known to accumulate around tumors (Maltby et al., 2009). Studies show that they may be important and sometimes essential in tumor angiogenesis, tumor growth and metastasis of tumors (Soucek, et al., 2007; Xiang et al., 2010). In an expression array study (Wensman et al, submitted manuscript) performed on mouse mast cells exposed to tumor conditioned medium, the gene 4-1BB was among the most up-regulated genes compared to control medium. 4-1BB codes for a membrane receptor protein of the tumor necrosis factor superfamily and has been shown to be important in T cell regulation in tumor diseases. This study was performed to investigate if human mast cells up-regulate 4-1BB when they get exposed to tumor conditioned medium.
