Effect of insulin during oocyte maturation in vitro on bovine early embryo development : partially evaluated by novel fluorescent staining

Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method. Bovine cumulus-oocyte-complexes (n=991) were aspirated from abattoir-derived ovaries.

Äktenskapet och det förändrade samhället : en kvalitativ studie om den förändrade giftermålsfrekvensen under 1900-talet

In the past, the meaning of marriage has been an agreement between two people to live together and have children in a legitimate manner. The marriage was not just to form a couple; it was also to merge two families together. From the early 1900s until today the allegation of marriage and its influence got a significant change compared to early societies which have aroused my interest to perform this into a research paper. My study is focused on marriage and social changes during the 1900s. Thoughts that arise now is that why there was a remarkable change in the marriage rate during the 1900s and whether there were any social changes had to do something with it.

Döden som rituellt medel

This essay consider ritual death during the ironage, and through a presentation of historical and archaeological sources. Considered ritual death I think we should study both historical and archaeological sources, to get a vider view and a new perspective. To make the essay easier to understand I have split up the early and the late Iron Age in the discussion. In order to study the ritual death I have shown archaeological examples like bogsacrifices in the early ironage, and decapitated victims in the Viking society. The victims have been considered as slaves by some archaeologist.

Priset på den svenska elmarknaden 1996-2002

Syftet med den här uppsatsen är att studera vad som har påverkat spotpriset på el i Sverige mellan åren 1996 och 2002. För att besvara syftet har de variabler som påverkar utbudet respektive efterfrågan, och därmed också spotpriset på el, identifierats med hjälp av traditionell ekonomisk teori. Därefter har en modell utformats och lösts med hjälp av Two-Stage Least Square metoden. De inkluderade variablerna i modellen är disponibel inkomst, pris på olja, teknologisk utveckling, kapacitet samt importerad kvantitet el. Förklaringsgraden på regressionen blev cirka 82 procent vilket tyder på att det kan finnas variabler som påverkar spotpriset på el som utelämnats från modellen.

Betydelsen av tidig hantering av nyanlända försökshundar till en försöksdjursavdelning :

AstraZeneca in Mölndal (AZRDM) uses beagles bred at Rååhöjdens kennel in Örkelljunga for their research purposes. The staff wishes to have mentally stable dogs to work with, sine stress can effect the research results. The purpose of this study was to put together the testresults from dogs delivered 2003 and 2004, to see if there is a connection between delivery age and testresult. We have also worked out a method to test if early planned handling of the dogs makes a difference on how the dogs later respond in a testsituation, and tried this method in a pilotstudy. The data that we have based our calculations on is 172 dogs, divided into 108 males and 64 females. We found a significant connection between the age at delivery and the testresult in contactability for female dogs delivered in 2003, where increasing age led to decreasing grades in the test at AZRDM. When looking at the difference in testresults between test number two at the kennel and the test at AZRDM we found a significant connection for female dogs delivered during 2003, ie the difference takes on a more negative value with increasing age at delivery. We found a difference between the two sexes in our calculations.

Individualiseringens dilemma : Hur uppnås ett fungerande samspel mellan individualisering och gemensam undervisning i matematik?

Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in theevent of rainfall. An increased level of radioactivity in the plants may occur due tointerception and retention of the radionuclides. If the content of the plants is above thethreshold limit value, entire yields may have to be destroyed. In order to preventcontamination or decrease the content countermeasures can be taken. The impact of thebiomass, leaf area index (LAI) and growth stage of the plant on the interception andretention is important to know in order to decide which countermeasures to use.Weather may also be an important factor.In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley andspring oil-seed rape was studied.

Tidig postoperativ övervakning av smådjur : förekomst av standardiserade rutiner

Background. Anesthetic-related death in small animal anesthesia is about ten times more common than in human anesthesia. Recent research identifies the early postoperative period as particularly risky and highlights the need for regular and careful monitoring of the veterinary patient during this period. Objective. The aims of this study were to investigate whether there are standard procedures in terms of regulated routine patient observations and record-keeping during the early postoperative period at Swedish veterinary clinics, and if there are any guidelines for monitoring the veterinary patient during recovery. Methods. A small survey including ten Swedish veterinary clinics was carried out as well as a literature review. Results.

Marcela Montgat och verkligheten

What is it that I do in my artistic work? And above all, what is it that I meet in the making? I become aware of a strong link between reality and art, for example, when I tell a fictional story on stage or compose, mirror, a human destiny in music. My compositions are, together with events before, during and after they've began to exist, an experience where I move between - sometimes I have chosen to express it - different dimensions of reality..

Information Audit en informationsgranskning vid Borås Stads äldre- och handikappomsorg inom kommundel Centrum.

An information audit identifies, among other things, organizations information resources, the information flow and the needs of the information users. The purpose of this masters thesis was to describe the management of information within a local unit of Borås municipality by putting an information audit-method in practice. The focus was on three issues: What information needs could be seen in the organization? How does the information flow through the organization? How does Sugan Henczels seven-stage model serve as a tool to map the management of information within the local unit? The study only described the situation at a certain time at the chosen organization. The seven-stage information audit model was revised and adjusted to the studied organization by only carrying out four of the seven steps: Planning, Data collection, Data analysis and Data evaluation.

Hypoadrenokorticism hos storpudel :

Hypoadrenocorticism (Addison´s disease) results from insufficient production of glucocorticoid and mineralcorticoid hormones from the adrenal glands. The disease is often difficult to diagnose in an Early stage because of the multitude of associated vague clinical signs. The standard poodle is one breed presupposed to be at higher risk of developing the disease. The purpose of this study was to give a review of canine hypoadrenocorticism as described in literature, and to characterise Addison´s disease in a population of standard poodles in Sweden. Statistics on incidenceproportions by breed for hypoadrenocorticism from the database of the Swedish insurance company Agria are presented.

Deadwood in piles or distributed : does it make any difference to saproxylic beetles?

Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
