Human fetal cerebral circulation - Perinatal Doppler velocimetry and fetal pulse oximetry studies

Popular Abstract in Swedish En majoritet av sk förlossningsskador med tecken på syrebrist i hjärnan uppstår troligen inte i samband med förlossning utan inträffar under graviditeten, ofta av okänt ursprung. Förlossningen är dock en stressituation med ökat krav på god blod- och syretillförsel till fostret. Övervakning med kardiotokografi (CTG) under förlossningen har inte påtagligt förändrat antaleThe studies upon which this thesis is based were designed to evaluate normal fetal and neonatal adaptation and the effects of obstetrical interventions during labor and delivery on fetal and neonatal cerebral circulation. Non-invasive Doppler ultrasound was used to record blood flow velocities from the middle cerebral artery (MCA) both antenatally from the fetus, and from the newborn in the early

Some effects of maternal anxiety on the fetus and on pregnancy outcome

The aim of this thesis was to study maternal emotional impact on the fetus and on pregnancy outcome. The thesis comprises five papers, which emanate from a prospective study regarding life situation, the experience of pregnancy, anxiety (Spielberger State-Trait Anxiety),and life events in nulliparous women, conducted in Malmö during 1988-1989. Examinations of fetal hemo-dynamics, fetal movements,

Law and participation

The issue of participation is of interest to scholars in law because of its relation to new forms of governance and regulation (Black 2000, 2001; de Burca and Scott 2006). Empirical studies of participation in biotechnology licensing show however that such procedures “itself may cause serious trouble when it is embedded in a formal procedure with a relatively strong legal framework.” (Bora & H

Interacting Compact Binaries: Modeling Mass Transfer in Eccentric Systems

We discuss mass transfer in eccentric binaries containing a white dwarf and a neutron star (WD-NS binaries). We show that such binaries are produced from field binaries following a series of mass transfer episodes that allow the white dwarf to form before the neutron star. We predict the orbital properties of binaries similar to the observed WD-NS binary J1141+6545, and show that they will undergo

Contact activation on bacterial surfaces - a virulence mechanism

Popular Abstract in Swedish En bakteries förmåga att orsaka sjukdom beror till viss del på vilka molekyler, så kallade virulensfaktorer, som bakterien kan utsöndra eller har på sin yta, samt på hur effektivt värdens immunförsvar är. I människans försvar mot infektioner spelar inflammation och koagulation en stor roll. Exempelvis kan infektionen avgränsas med ett olösligt koagel och vita blodkroppaLife-threatening conditions from bacterial infections are a major clinical problem. During a severe infection, the host responds by a massive release of pro-inflammatory mediators together with a systemic activation of systems such as the coagulation, fibrinolytic, and complement systems. These events could result in the development of complications such as disseminated intravascular coagulation a

Recombinant protein purification using thermoseparating aqueous two-phase systems

The biotechnology industry has grown considerably over the past twenty years, and the revolution within the field of molecular biology has dramatically improved the possibilities of producing proteins and other important biomolecules. The product of interest will be obtained in a multi-component solution and some challenging purification work has to be performed to recover the target molecule in a

The external mycorrhizal mycelium - growth and interactions with saprophytic microorganisms

Popular Abstract in Swedish Mykorrhiza är symbiosen mellan växters rötter och olika svampar. När en symbios har etablerats i en rot växer svampens mycel ut i marken och tar där upp näring som levereras till växten. I denna avhandling studerades hur man kan mäta detta mycel i marken med hjälp av biokemiska markörer. Vidare studerades hur detta myces påverkar övriga mikroorganismer i marken.The interactions between external mycorrhizal mycelia and saprophytic microorganisms were studied in experiments with growth chambers specially designed to enable the mycelia to develop in root-free soil compartments. The growth of the mycorrhizal mycelia was estimated by use of biochemical signature compounds. It was shown possible to estimate the biomass of the external mycelium of different ar

Plagiat i samband med programmering – problem, detektering och förebyggande pedagogiska strategier

I denna artikel behandlar vi frågeställningar rörande plagiat i samband med programmering. Problematiken är relevant även för andra ämnen där man använder programmering som problemlösningsmetod eller där man använder ett begränsat formellt språk för redovisningar som t.ex. inom matematik. Vi diskuterar skillnader mellan program¬pla¬giering och uppsatsplagiering samt vilka system som finns för dete

Towards the Rational Design of Molecularly Imprinted Polymers

Popular Abstract in Swedish Gipsgjutning är ganska enkelt. Blanda gipset med vatten och rör runt lite. Häll därefter blandningen i en form om du vill ha en gipshund eller så, eller i en tallrik om du vill trycka av en kroppsdel. Om du vill ha en handavgjutning så tryck dit handen en stund och låt gipset stelna. Sedan är det klart. Bara den hand du gjutit av kommer att passa; var det högerhanden såMolecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. Monomer-template complexes are formed and subsequently fixed through polymerisation, and following removal of the template species from the resultant molecularly imprinted polymer,
