Tre metoder för diagnos av mastit i fält :
The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings.
DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations.
Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.
Tillförlitlighet i klinisk användning för två förståelighetstest på svenska för barn i åldrarna 4-10 år
Intelligibility is a central concept in speech-language pathology regarding assessment and treatment of speech. At present, there is no reliable or valid Swedish test for measuring intelligibility. The main purpose of the current study was to conduct a clinical trial of the computer-based intelligibility test ?Swedish test of intelligibility for children? and to investigate the test?s reliability. Another purpose was to investigate the reliability of the rating form ?Intelligibility in context scale?.
Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen
Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.
Kan D-vitamintillskott minska depressiva symtom?
Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized Clinical trials, be conducted on humans, written in English.

Fröodling av Raj- och rörsvingel i Sverige
Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Cow?s milk and chronic constipation in children ? A systematic reviewAuthor: Sara Palm & Anna SvenssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 27, 2014Background: Chronic functional constipation is common among children. Up to a third of all who seek a paediatrician suffer from constipation and it is a widespread problem for children in many countries. Lately it has been discussed if cow?s milk can be a cause of the constipation and if it should be considered a delayed hypersensitivity.Objective: The aim of this systematic review is to examine whether there is scientific evidence to recommend a cow?s milk-free diet as a potential treatment in chronically constipated children.Search strategy: The literature searches were performed in the databases Pubmed, Scopus and the Cochrane library, using the search terms cow?s milk, constipation, milk proteins, dairy products, milk hypersensitivity, cow milk and cows milk between March 17th and April 4th 2014.Selection criteria: Randomized controlled trials measuring stool frequency in chronically constipated children on a cow?s milk-free diet were included.
Föräldraprogrammet De otroliga åren i klinisk praxis: En utvärdering med långtidsuppföljning
The purpose of this study was to examine the impact of the parent training The Incredible Years in clinical settings. The study included 33 families in clinical practice. There were two parts to the study; a main part with a before and after measurement, and a follow-up study on 12 children one year later. On baseline the children (3-9 years) as a group were on the borderline clinical range, (M = 61.8), with 70 % of the children in the borderline or clinical range. The childrens emotional and behavioral problems were measured with Child Behavior Checklist (CBCL).
The WT1-gene ? its role in tumourigenesis and prospects for developing a vaccine
The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).
Patienters erfarenheter av att delta i forskning : En litteraturöversikt
Bakgrund: Forskning- och utvecklingsarbete är något som bedrivs på många håll inom hälso- och sjukvården. Detta innebär att många patienter som söker vård och behandling kan komma att tillfrågas om att delta i forskning. En person som är sjuk, och i behov av vård, kan uppleva att man i patientrollen hamnar i en beroendeställning i förhållande till vårdpersonalen. Patienten är den hjälpsökande och vårdpersonalen är de som på grund av kunskap och förmåga att hjälpa patienten har en starkare ställning. Att vara patient och medverka i forskning kan innebära att patienten får ökad uppmärksamhet men patienten kan också uppleva att beroendeställningen gentemot vårdpersonalen förstärks.Syfte: Syftet var att beskriva patienters erfarenheter av att delta i forskning.Metod: En litteraturöversikt har gjorts där tio vetenskapliga, kvalitativa artiklar, med begränsning vuxna patienter, har utgjort grunden till resultatet.Resultat: Resultatet presenteras i fyra kategorier, vilka är; Överväganden inför beslut om att delta i forskning, Meningsfullhet av att delta i forskning, Upplevelse av hinder i samband med forskning samt Från känslan av stöd ? till känslan av övergivenhet.Diskussion: Resultatet har diskuterats i relation till livsvärldsperspektivet enligt Dahlberg och Segesten.

Lokalisationen av osteochondrosförändringar hos svenska halvblodshästar :
The aetiology of osteochondrosis (OC) is known to be complex and multifactorial. The occurrence of bone fragments in joints and their connection to osteochondral disease are no exception. In the hock and stifle joint of the horse this type of lesion has generally been considered to be of osteochondral origin, while the process behind these fragments in the fetlock joint has been up for discussion.
The objective of this study was to determine the frequency and the localisation of OC in Swedish warmblooded horses. In order to do so all radiographs of stifle, hock and fetlock joints performed on Swedish warmblooded horses during the period of 1992-1999 at Regiondjursjukhuset in Helsingborg were examined and the material was divided into two groups.
Biologisk bekämpning av Fusarium graminearum
Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.
