Vitrification in sealed containers : Evaluation of a new technique (Rapid-i?) for cleavage stage embryos and blastocysts

Ovarian stimulation in assisted reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

Background: In small animal healthcare fluid therapy is an important area. To get an adequate treatment there are several factors that may play important roles in this matter. One of these factors is the correct use of the administration technique. Aim: The aim was to investigate how correct the amount of prescribed fluid was given when different people set up a fluid administration set. Method: An experimental study was performed to compare two different infusion techniques.

Är korta spenar ett problem i samband med mjölkning? :

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

Smal, smalare, smalast: en jämförande studie mellan Pro-ana och det "normala" smalhetsidealet

Syftet med studien är att undersöka Pro-anorexia (Pro-ana) bilders påverkan på kvinnor jämfört med vedertagna modellbilders påverkan. Blir kvinnor mer påverkade av att titta på extremt smala kvinnor än av att titta på "normala" smala modeller? En experimentell mellangruppsdesign, med 42 kvinnor från Lunds universitet användes. Den påverkan som mättes var matproblematik, tjockkänsla, idealkropp, självförtroende och affekter. Pro-anafilmer, modellfilmer och kontrollfilmer användes som stimulimaterial.

Meningen bakom det anorektiska beteendet: en kvalitativ studie av sju kvinnors upplevelser av anorexia nervosa

Denna kvalitativa studie undersöker vilken funktion det anorektiska beteendet fyller och huruvida det finns en koppling till hantering av adolescensens utvecklingsuppgifter. Sju semistrukturerade intervjuer genomfördes med kvinnor från en icke-klinisk population som hade haft en ätstörning i tonåren. Studien visar att ätstörningen används för att hantera känslor, få en känsla av självkontroll, identitet, trygghet och självförtroende, kommunicera att man inte mår bra, få uppmärksamhet, skapa gränser samt frigöra sig eller undvika att frigöra sig från föräldrarna. Resultatet pekar på att flera av dessa sjukdomsvinster kan användas för att hantera adolescensens utvecklingsuppgifter. I studien ingår även en screeningundersökning bland universitetsstuderande (n= 406), som fann en prevalens på 6.5 % hos kvinnor respektive 2.8 % hos män för anorexia nervosa i tonåren..

Kateterrelaterade urinvägsinfektioner ? brist på effektiva preventioner ? En litteratursammanställning

Background: Urinary tract infections caused by indwelling urinary catheters causes unneccesay suffering among those it affects. These infections are also financially straining on the health care services. It is therefore of importance to gain knowledge about which evidence based preventive interventions that have the possibility to reduce the risk for bacteriuria and urinary tract infections among patients with indwelling urinary catheters. Aim: This study aimed to compile available knowledge concerning i) if silver alloy catheters does reduce bacteriuria in this patient group, ii) if aseptic catheterization does reduce bacteriuria in this patientgroup, iii) which routines for changing the urinary drainage bag reduces the risk of bacteriuria, iv) which routine genital hygenic care reduces the risk of bacteriuria? Method: Litterature was searched for in the data bases Cinahl, Medline and The Cochrane Library using the data bases? thesaurius combined with OR/AND.

Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

Botulism hos svenska hästar :

Botulism is a serious disease with high mortality that can affect horses. Due to this about 20-30 percent of the horses in Sweden are vaccinated against botulism. The purpose of this study was to see how common botulism is in the Swedish horse population and to se if a connection between feeding with haylage and botulism could be seen. In addition to this, the study aimed to find how common vaccination against botulism is among Swedish horses and on what grounds the diagnosis botulism is made. Medical records of horses being diagnosed with botulism at all the major large animal hospitals in Sweden between 1995-2005 were searched. In addition to this the database where general practitioners report their cases as well as the cases with botulism reported to the insurance companies were included. The results of this study show that only 0,03 percent of the Swedish horse population has been diagnosed with botulism during the time period this study covers. In all the cases included in this study the diagnosis was made based on clinical signs and in none of the cases verification by isolating the toxin was possible. In all cases where forage is noted in the journals the horse has been feed haylage which indicate that there is a connection between the use of haylage and botulism. Three horses died despite being partially vaccinated against botulism type B which indicate that a correct vaccination has to be done before the horse get any protection or that the correct diagnosis was not botulism type B..

Förekomst av Giardia i symtomfria valpkullar :

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

Läsförmåga hos elever i årkurs 4 och 6 : med avseende på fakta- och inferensfrågor samt lässätt

The aim of the present study was to examine students' text comprehension in grades 4 and 6. Participants were 61 students without documented or suspected reading and writing difficulties, in grades 4 and 6. The focus was on texts designed by Bishop and Adams (1992), containing two types of questions: literal and inference questions, and three different ways of presenting the text; listening, silent reading and silent reading with the text available when responding to the questions. The texts have been previously used in research and as a tool for clinical, qualitative estimate of reading comprehension in speech and language pathologists? assessments.

Kvalitetssäkring av bendensitometri

Osteoporos eller benskörhet, är en folksjukdom som vanligen inträffar i samband med åldrandet. För att kunna diagnostisera, upptäcka och följa frakturrisk i god tid är det bra om en bentäthetsmätning görs. Bentäthetsmätning eller bendensitometri utnyttjar metoden Dual energy x-ray absorptiometry (DXA). För att kunna bedöma metodens reproducerbarhet rekommenderas att periodvis genomföra en kvalitetssäkring vid bentäthetsmätning, eftersom det är en kvantitativ mätning. Syftet med studien var att kvalitetssäkra metoden för bentäthetsmätning.

Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

Validation of KIDScore? D3 Basic, a morphokinetic model for improved embryo selection

ABSTRACT Infertility is a medical condition that affects approximately 16 % of Swedish couples in childbearing age and is a condition found in both men and women. When a couple has been trying to conceive for more than 12 months without success they need to see a health care provider. Infertility can be treated with medicine, insemination or assisted reproductive technology such as in-vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). The aim of this study was to validate a morphokinetic selection model, KIDScore? D3 Basic, against morphological selection model that is currently in use at the Fertility unit at University hospital in Orebro.

Egyptiernas föreställningar om döden : en diskursiv analys av Dödsbokens formler

The Egyptian religion viewed the whole world as divine and inhabited by both gods and men. Concepts such as death was therefore explained through myths. The ancient society feared death but desired an eternal life. The Egyptians saw death as a physical dismemberment of the body as had happened in the myth of Osiris when death was first introduced to the world. Osiris functioned as a prototype for all men as he had overcome death by finding a new existence in the netherworld.
