Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

ECG-Screening for young elite athletesAbstractBackgroundSudden cardiac death (SCD) during physical activity is a frightening and emotional tragedy that draws huge media attentions when it occurs. Fortunately it is a relatively uncommon occurrence but happens nonetheless to young athletes who often seems to be in perfect health. SCD is used as a term for sudden unexpected complications on the cardiovascular system that leads to a deadly outcome normally within the first hour of onset of symptoms and the cause is some sort of underlying cardiovascular disease that gets triggered by physical activity.Normally athletes gets divided into two groups dependent on age, over and under 35 years, and this studies focus is on the younger group since it is often during this period athletes are at the elite level. It is also in this category the most unexpected sudden deaths occur that is not due to coronary atherosclerosis, which is the dominant cause of death, and drastically increases, for people over 35 years old.AimThe aim of this study was to scientific and unbiased analyze peer-reviewed clinical articles todescribe the pros, cons and cost to implement an ECG-screening as a standard before physicalactivities for specifically defined elite athletes.MethodA systematic review was performed and after all data collection 21 articles was chosen to beused as a base for both background and analyze. At the end 10 articles was fulfilling the criteria to be used at the analyze and later the results.ResultsThe implementation of ECG-screening has reduced SCD in Italy by 89 % between the years 1979-2004.

The writing style of a particular author can be divided into many subfeatures, for example use of words, language and syntax. Focusing on the latter, this study aims to show how well syntactic information alone can attribute the correct author to a document. Syntactic information is defined as overlapping syntactic subtrees of height one (1) for all sentences of all included documents. The performance is compared to that of the previously very successful method of comparing stop word frequencies. These are words normally excluded from search engine queries, because they are present in all sorts of texts regardless of topic.

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Borrelios är den vanligaste vektorburna infektionssjukdomen i Europa och orsakas av bakteriekomplexet Borrelia burgdorferi sensu lato. Bakterien har en livscykel som involverar olika reservoarer och den överförs mellan dessa med hjälp av fästingar. Bakterien förekommer främst i fästingens mag-tarmkanal men kan också sprida sig systemiskt vilket kan påverka smittöverföringen. Fästingens utbredning i Sverige har ökat sedan början av 1990-talet, vilket tycks bero på ett varmare klimat i kombination med ökad tillgång till värddjur. Den här litteraturstudien syftar till att undersöka sambanden mellan ett varmare klimat och förekomsten av borrelios i Sverige. Klimatet har stor påverkan på fästingen och den har visat sig känslig för uttorkning och kräver en hög relativ luftfuktighet för att överleva.

Causes of thrombocytopenia in dogs ? a retrospective study of 123 cases The purpose of this retrospective case study was to determine which diseases are associated with thrombocytopenia in Swedish dogs. Records of 123 dogs with thrombocytopenia were evaluated. The most common cause was neoplasia-associated thrombocytopenia (32%). The largest proportion within this group was unspecified neoplasia.

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

Touch that is performed in a sensitive and gentle way can be a good complement in caring. To be stricken with illness can involve that the individual feels powerlessness and to have no control over the own body. This could lead to both psychical and physical suffering. To strength health is one of the nurses' responsibilities and to touch can be one way. The aim of the study was to describe patients' experience of the effects of touch.

Interaktioner mellan vilda herbivorer och nötboskap är väldigt komplexa. Bland nackdelarna väger överföring av sjukdomar tyngst. Uppskattningsvis har cirka 70 % av alla sjukdomar hos boskap (inklusive zoonoser) som uppkommit på senare tid sitt ursprung hos vilda djur. Sjukdomar kan spridas via direkta kontakter eller indirekta interaktioner (luft, kroppsvätskor, avföring, kött eller mjölk) mellan vilda djur och boskap. Några exempel på sådana sjukdomar är: East Coast Fever, Corridor disease, January disease, katarralfeber, trypanosomos samt mul- och klövsjuka.

Aphasia is a disease that brings on disability. The purpose of the study is to describe the daily life when afflicted with aphasia and gain a deeper understanding of persons with aphasia in working ages. The study was made with a qualitative approach with a combination of data sources; literature, internet lectures, live lectures, interviews with personnel in medical and educational services and three persons with aphasia. More research in aphasiology is welcome. This may be aimed at developing knowledge about the importance of communication, of active participation in the social environment, and the achievement of improved attitudes towards people with disabilities. The study should give rehabilitation actors and close relations knowledge and support in their action when they meet people with aphasia..

Malt lymphoma is a malignant disease that can arise in a variety of extra nodal sites. Previous studies indicate that tumour arise from more mature B-cells.Our purpose was to examine the presence of clonality and somatic hypermutation of immunoglobulin (IgV?) of MALT lymphomas.Paraffin-embedded tumour samples from13 MALT lymphoma were subjected to rearrangement analysis, by using PCR, heteroduplex gels and sequence analysis.Successful amplification was seen in 10/13 cases and sequences of IgV? genes were obtained in 6/13, all of them were mutated. The percentage of mutation compared to germline sequences was 1,1% to 8,6% monoclonal rearrangemang. It was demonstrated that 5 of 7 clones were derived from the V?3 family, 2 from V?1 and 1 from the V? 4 family..
