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.

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.

"Aspergers syndrom är jag" En kvalitativ studie om hur det kan vara att leva med Aspergers syndrom

Asperger´s syndrome is a state with certain difficulties in social relations, communication and perception. People with Asperger´s syndrome often have a special interest for a certain topic. The main purpose of this study was to describe how grown people with Asperger´s syndrome make sense of living with Asperger´s syndrome. The inquiry was based on semi-structured interviews with eight persons with Asperger´s syndrome. We reached those subjects trough interest organisations for people with Asperger´s syndrome.

Technologised Parenthood: An Ethical Implacation of Human Reproductive Cloning

Science and technology has been the bedrock of human growth and dynamism. Man has over the years distinguished his existence from all other beings by his ability to champion and fashion his existence. Among his tools is biotechnology which actually attenuates the fears of aging and death.Human reproductive cloning stands out as one of the means through which biotechnology plans to achieve this perfect existence for man. Technological advancements in the field of biotechnology are now in the threshold of human procreation.Human reproductive cloning is seen as an assisted method of reproduction which creates a newborn that is genetically identical to another human being.Human reproductive cloning as a technology and as a means of reproduction is not without its pros and cons. In as much as the technology promises to mention but a few, hope for the infertile couples and single parents, as well as the hope of reproduction without passing on hereditary diseases; it at the same time beeps some flashes of worry.

Kirurgi vid Superior Canal Dehiscence Syndrome ? En beskrivande litteraturstudie om audiologiska och vestibulära resultat och komplikationer

Superior Canal Dehiscence Syndrome (SCDS) is a newly described syndrome with symptoms including sound- and pressure induced vertigo, conductive hyperacusis and autophony. SCDS is caused by absence of bone overlying the superior semicircular canal and can be surgically treated. As the syndrome and surgical technique is new, it is of importance to study possible postoperative outcomes..

Dynamic obstructions of the equine upper respiratory tract

Dysfunction of the upper respiratory tract is a common cause of impaired performance and intolerance to exercise in racehorses and include several upper airway obstructions. The ones termed dynamic obstructions are primarily seen during physical exertion and affected horses often appear to be normal during endoscope examination at rest. The correlation between diagnoses made at rest respectively exercise is low, suggesting that an examination at rest alone is likely to be insufficient. The upper respiratory tract is exposed to great differences in pressure throughout the respiratory cycle; variations that are further altered during strenuous exercise and affect the rigidity of upper airway structures. In presence of great fluctuations in pressure, stability is achieved through coordinated and synchronous neuromuscular mechanisms. Due to nerve damage or anatomical abnormalities, these functions may be disrupted and further cause a dynamic collapse of the upper respiratory tract when pressure changes become too severe. The etiology behind the neuromuscular dysfunction is not yet fully understood.

"Man kan säga att båda sänder signaler men på olika frekvenser" : en kvalitativ studie om partners upplevelse av att vara i ett parförhållande där den andra partnern har Aspergers syndrom

Being in a relationship where the partner has Asperger's syndrome makes you indirectly affected by their disability as it affects not only the disabled but also the partner. The partner may be faced with a lack of understanding from their partner with Asperger's syndrome and from its surroundings, where the syndrome including causes, limits ability in social interaction and communication.The study is a qualitative study based on six asynchronous interviews conducted via email with partners who are in a relationship with a partner who has Asperger's syndrome.The aim of the study was to increase understanding and to highlight partners experience to be in a relationship where the other partner has Asperger's syndrome and how outside support from the environment is perceived. Results of the study showed that all six partners felt that everyday life was structured around the partner with Asperger's syndrome. There was a perceived feeling of loneliness because of the partner with Asperger's syndrome not caring about the partner and of being the one taking the greatest responsibility in everyday life for it to work. There was a feeling of stress, anxiety, lost confidence and frustration but there was also a strong desire and commitment to their partner with Asperger's syndrome.

Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin

The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..

Fysisk aktivitet hos personer med metabolt syndrom

A quart of the of the adult population worldwide havemetabolic syndrome. A sedentary lifestyle, low physicalactivity, combined with wrong eating habits, stress,smoking and psychosocial factors, are the main causes ofdevelopment of the metabolic syndrome. The purpose ofthe literature review was to illuminate the physicalactivity in persons who have the metabolic syndrome, andwhat sort of advice a nurse use in the promotion ofphysical activity. The study was conducted as a literaturereview, including 15 scientific quantitative articles. In tenarticles, the focus was on physical activity at themetabolic syndrome, and five articles focused on variousforms of counselling for physical activity.

Kvinnors preventivmedelsanvändning under olika faser av det reproduktiva livet

Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal reproductive life.

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.

Primär ciliär dyskinesi som orsak till kronisk lungsjukdom hos hund : en litteraturstudie och fallpresentation

Primary ciliary dyskinesia (PCD) is an important but unusual cause of chronic respiratory disease of young dogs. The purpuse of this paper is to study and present internationally publicated papers on PCD in dogs and present three dogs, in which PCD was suspected. PCD has been reported in many dog breeds as well as in people. In dogs an humans, PCD is caused by inborn genetical defects which causes structural and functional abnormalities of cilia in the respiratory organs and other cilia in the body. Situs inversus occurs in about half the cases in people and probably in dogs as well. Respiratory signs usually predominate.

Retrospektiv studie av porcint circovirus typ 2 och postweaning multisystemic wasting syndrome i Sverige :

Porcine circovirus type 2 (PCV2) is a common virus present in most parts of the world. PCV2 has been pointed out as the major causative agent to post weaning multisystemic wasting syndrome (PMWS) that affects pigs after weaning. The clinical symptoms of PMWS are impaired growth, diarrhoea, respiratory problems and increased mortality. At autopsy enlarged lymph nodes with depletion of lymphocytes are commonly found. Since 1991 PMWS has spread all over the world and was first described among Swedish pigs in 2003. Although PCV2 is widespread, only some pigs develop PCV2-related diseases. Why this is and what other factors that are required in order for the disease to develop is yet unknown. The main theories involve other infections, for example PRRS, and management issues but also genetic differences between pigs and/or virus strains have been suggested.

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.
