Objective: To explore middle cerebral artery (MCA) and anterior cerebral artery (ACA) blood flow responses to superimposed acute hypoxemia in growth -restricted fetuses with and without established brain-sparing flow during basal conditions. Material and methods: 47 term fetuses suspected of growth restriction were exposed to an oxytocin challenge test with simultaneous cardiotocography and Dopple
Popular Abstract in Swedish Jämte korrosionsangrepp är skador på grund av saltfrostangrepp den vanligaste skadetypen hos betongkonstruktioner som utsätts för miljöer med fukt, salt och frost. Exempel på sådana miljöer är marina miljöer och tösaltade vägmiljöer. Betongens saltfrostbeständighet bestäms till stor del av betongsammansättningen, främst av förhållandet mellan mängden vatten och cement oAbstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. Specimens of ‘micro’-concrete, either with OPC alone as the binder or with silica or slag as part of the binder, were freeze/thaw tested at different ages after casting. Prior to testing, the sp
In a Northern country such as Sweden, energy use in the home may be reduced by 20% through changes in behaviour. However, little is known about how households respond to policy instruments encouraging such change or to what degree this in turn may affect the workload of women and men in such communities. The current study presents findings from interviews with 30 households in Sweden that particip
The MAX-IV storage rings are being studied at MAX-Lab. In this paper, we present the magnetic measurements of the soft bending magnet prototype. The magnet is introduced in the matching section of the 3 GeV storage ring lattice [Tarawneh, Proceedings of European Particle Accelerator Conference, July 2004, Lucerne, Switzerland] mainly to reduce the power of the synchrotron radiation hitting the ups
Objective: Glucose degradation products (GDPs) in peritoneal dialysis (PD) fluids are cytotoxic and affect the survival of the peritoneal membrane. One of the most reactive GDPs in PD fluids is 3,4-dideoxyglucosone-3-ene (3,4-DGE). 3,4-DGE has been reported as an intermediate between 3-deoxyglucosone (3-DG) and 5-hydroxymethyl furaldehyde (5-HMF) during degradation of glucose. In PD fluids, 3,4-DG
After permanent ligation of the middle cerebral artery the motor function of rats housed in an enriched environment, i.e. cages with opportunities for various activities but not forcing the rats to do any particular task, is significantly better than in rats housed in individual cages. Rats kept in an enriched environment before and after MCA ligation improved sooner and slightly more than those p
Twelve healthy women with regular menstrual cycles were examined with a combination of two-dimensional real-time ultrasound and color and spectral Doppler techniques on cycle days 4 and 8 and daily from cycle day 12 until follicular rupture, then days + 1, +2, +5, +7 and +12 after follicular rupture. The uterine and subendometrial arteries, arteries in the ovarian stroma and hilum, in the wall of
DIGITAL ANALYSIS OF CARDIAC ACOUSTIC SIGNALS IN CHILDREN Milad El-Segaier, MD Division of Paediatric Cardiology, Department of Paediatrics, Lund University Hospital, Lund, Sweden SUMMARY Despite tremendous development in cardiac imaging, use of the stethoscope and cardiac auscultation remains the primary diagnostic tool in evaluation of cardiac pathology. With the advent of miniaturized and po
Popular Abstract in Swedish Stroke (även kallat slaganfall) är den tredje vanligaste dödsorsaken efter hjärtsjukdom och cancer i stora delar av världen. Strokesjukdomen består av blodpropp (hjärninfarkt), blödning i hjärnan (intracerebral blödning) eller blödning i dess hinnor (subaraknoidal blödning). Stroke definieras enligt WHO som snabbt påkomna neurologiska symptom (t.ex. förlamning, talsvåriBackground: Stroke is a major cause of death and disability. Investigations of the epidemiological trends for stroke might result in better understanding of stroke pathogenesis and prevention. Methods: The trends of first-ever stroke incidence and survival over 3 time periods (1983-85, 1993-95 and 2001/2002) in Lund-Orup health care district were studied. The first 2 study periods were retrospect
The association behaviour of a number of glucitol amine gemini surfactants has been investigated by means of molecular dynamics and self-consistent-field calculations. We have shown that the titratable head group of the surfactant is responsible for a micelle-to-membrane transition when changing the pH. Furthermore, the association structure of this group of surfactants is shown to be very sensiti
