Interaction of bovine coagulation factor X and its glutamic-acid-containing fragments with phospholipid membranes. A surface plasmon resonance study.

The interaction of blood coagulation factor X and its Gla-containing fragments with negatively charged phospholipid membranes composed of 25 mol% phosphatidylserine (PtdSer) and 75 mol% phosphatidylcholine (PtdCho) was studied by surface plasmon resonance. The binding to 100 mol% PtdCho membranes was negligible. The calcium dependence in the membrane binding was evaluated for intact bovine factor

Breeding synchrony does not affect extra-pair paternity in great reed warblers

Breeding synchrony is hypothesised to influence the occurrence and frequency of extra-pair fertilisations (EPFs) in birds irrespective of the social mating system. The two proposed hypotheses make opposite predictions. (1) Synchronous breeding leads to a lower frequency of EPFs because males face a trade-off between mate guarding and obtaining additional matings via extra-pair copulations (EPCs) (

Preoperative vestibular ablation with gentamicin and vestibular 'prehab' enhance postoperative recovery after surgery for pontine angle tumours - first report

Conclusions. Preoperative gentamicin in combination with vestibular 'prehab' offers a possibility to reduce postoperative malaise and speed up recovery and may be used for patients undergoing such surgery when there is remaining vestibular function. Objectives. Removal of pontine angle tumours in a patient with remaining vestibular function causes symptoms of acute vestibular loss. A simultaneous

De hjälper oss till rätta : normaliseringsarbete, självbestämmande och människor med psykisk utvecklingsstörning

For people with learning disabilities care in institutions has been replaced by a life in community settings e.g. group homes, where a number of persons (4-5) are living with staff support. My case-studies cover three elderly and three more lately produced such units as well as a ward in a nursing home. Data were gathered through participant observations and semistructured interviews with staff an

Continued transmission of hepatitis B and C viruses, but no transmission of human immunodeficiency virus among intravenous drug users participating in a syringe/needle exchange program

The virological efficacy of a syringe/needle exchange program was evaluated in a cohort incidence study. Of 698 intravenous drug users (IVDUs) initially recruited, 15 (2.1%) were HIV-positive at baseline. Adequate follow-up was possible in 515 (74%) and showed no new cases of HIV infection during a median of 31 months. Most IVDUs had been previously exposed to HBV (anti-HBc-positive 70.1%) and HCV

Influence of street characteristics, driver category and car performance on urban driving patterns

Driving patterns (i.e., speed, acceleration and choice of gears) influence exhaust emissions and fuel consumption. The aim here is to obtain a better understanding of the variables that affect driving patterns, by determining the extent they are influenced by street characteristics and/or driver-car categories. A data set of over 14,000 driving patterns registered in actual traffic is used. The re

Impact on Economic Growth of Investing in Maternal-Newborn Health

The aim of this paper is to provide a systematic review of the evidence of the impact on economic growth of investments in maternal--newborn health (MNH). The methodology used for the review includes a systematic search for published literature in relevant electronic databases. In the paper, we review five studies: four empirical and one theoretical. One of the empirical papers measures health by

What makes some persons more prejudiced than others? Modeling the role of social dominance, empathy, social desirability, and gender

Structural equation modeling on questionnaire data showed that different kinds of prejudice (concerning sexual orientation, ethnicity, gender, and impaired develop­ment) can be represented as a general prejudice factor. Specific variability related to classical and modern prejudice only increased model fit marginally. Several causal models of the relation between key individual difference variable

Exciton fine structure splitting in InP quantum dots in GaInP

We have investigated the electronic structure of excitons in InP quantum dots in GaInP. The exciton is theoretically expected to have four states. Two of the states are allowed to optically decay to the ground ( vacuum) state in the dipole approximation. We see these two lines in photoluminescence (PL) experiments and find that the splitting between the lines ( the fine structure splitting) is 150

Modified stainless steel surfaces targeted to reduce fouling - Evaluation of fouling by milk components

Several stainless steel based surfaces with different properties were evaluated according to their fouling behaviour for different dairy products under different conditions. Surface properties were obtained by the following modification techniques: SiF3+, MoS22+ and TiC ion implantation; diamond-like carbon (DLC) sputtering; DLC, DLC-Si-O and SiOx, plasma enhanced chemical vapor Deposition (PECVD)

The Substituted Judgment Standard. Studies on the Ethics of Surrogate Decision Making

Popular Abstract in Swedish Beslutsinkompetenta patienter behöver en ställföreträdande beslutsfattare som kan fatta vårdbeslut för deras räkning. En av de etiska frågor som aktualiseras i detta sammanhang är vilka riktlinjer som bör gälla för sådant beslutsfattande. Enligt ?the Substituted Judgment Standard? (SJS) bör en ställföreträdare fatta det beslut som patienten själv hade fattat, om denne hPatients who are incompetent need a surrogate decision maker to make treatment decisons on their behalf. One of the main ethical questions that arise in this context is what standard ought to govern such decision making. According to the Substituted Judgment Standard (SJS), a surrogate ought to make the decision that the patient would have made, had he or she been competent. Although this standard

Lidar Techniques for Environmental Monitoring

Popular Abstract in Swedish Ljus kan beskrivas som en elektromagnetisk våg och har då en viss våglängd. Färgen på ljuset förändras beroende på våglängden. Av det synliga ljuset har violett ljus den kortaste våglängden och rött ljus den längsta. Det finns även elektromagnetisk strålning utanför det synliga området, från Röntgenstrålning till radiovågor. Det vi kallar det optiska området sträcker siAtoms and molecules absorb and emit light at certain, welldefined wavelengths, and this forms the basis of spectroscopy. The wavelengths are given by the discrete energy levels of the atoms/molecules. When illuminated by light of a suitable wavelength, the light will be absorbed, making it possible to deduce information on the presence and concentration of various elements and compounds. When ato

Shaping variables in service level agreements at application level

In a web service environment, such as Parlay X, contracts are agreed between the involved participants to guarantee a reasonable measure of Quality of Service (QoS). A common policy adopted is for contracts to involve only one parameter which places a limit on the number of incoming operation calls. This constraint is expressed as the maximum number of operation calls per second that a source is a
