Obiectives: Ventricular septal rupture is a rare but feared complication after acute myocardial infarction. Most reports about outcome after surgical treatment are single center experiences. We investigated the results after surgical repair in all patients in Sweden during a 7-year period. Methods: All patients undergoing surgical repair 1992-1998 were identified with the aid of the Swedish Heart
Time series analysis of herbivore data with weather included as covariate is commonly used as a mean to shed light on the state and ecology of the studied population. Conclusions about the herbivore population are drawn from statistical parameter values and presence/absence in the most parsimonious model. However, this procedure is only reliable if the statistical parameters have general interpret
Recent findings indicate that the interactions among CO2, temperature and water can be substantial, and that the combined effects on the biological systems of several factors may not be predicted from experiments with one or a few factors. Therefore realistic multifactorial experiments involving a larger set of main factors are needed. We describe a new Danish climate change-related field scale ex
Purpose: Single-photon emission computed tomography (SPECT) of striatal dopamine transporters (DAT) has been used to demonstrate presynaptic dopaminergic dysfunction and to monitor the progression of Parkinson's disease. In parkinsonian patients who were implanted with embryonic mesencephalic tissue in the striatum, positron emission tomography (PET) has shown an increase in striatal [F-18]dopa up
We simulate interactions between adsorbing and nonadsorbing surfaces immersed in solutions containing monodisperse semiflexible chains. Apart from the nature of the surfaces, we investigate responses to changes of the intrinsic chain stiffness, the degree of polymerization, and the bulk concentration. Our simulations display a sufficient accuracy and precision to reveal free-energy barriers that a
The ability to store energy is an important life history trait for organisms facing long periods without energy income, and in particular for capital breeders such as temperate zone amphibians, which rely on stored energy during reproduction. However, large scale comparative studies of energy stores in populations with different environmental constraints on energy allocation are scarce. We investi
The Gaia space astrometry mission (to be launched in 2012) will use a continuously spinning spacecraft to construct a global system of positions, proper motions and absolute parallaxes from relative position measurements made in an astrometric focal plane. This astrometric reduction can be cast as a classical least-squares problem, and the adopted baseline method for its solution uses a simple ite
The current and future emissions regulations and demands on internal combustion engines have increased the need for improvement of the thermal design and engine ef ciency. This paper reports an initial investigation concerning in-cylinder heat transfer. In addition, a literature review in this eld is presented. It was found that no extensive application studies have been performed on full cylinder
Critics maintain that there are a number of troublesome issues resulting from the construction sector’s way of operating and that these remain, despite widespread criticism and measures designed to change all of this. The construction sector’s and the critics’ manner of describing these problems fails to a large extent to take into consideration the way people function in connection with practical
Popular Abstract in Swedish Det är en utmaning att behandla patienter med allvarliga infektioner eftersom immunförsvaret reagerar olika på olika mikroorganismer. Immunförsvarets reaktion har i sin tur en stor betydelse för symtombild, kliniska fynd och prognos. Vid blodförgiftning (sepsis) förändras dessutom sannolikt immunsvaret under det kliniska förloppet. Man tror att det inledningsvis vid sep
The apolipoprotein E (ApoE) epsilon 4 allele is the strongest risk factor of sporadic Alzheimer's disease (AD), however, the fluid concentrations of ApoE and its different isoforms (ApoE2, ApoE3 and ApoE4) in AD patients and among APOE genotypes (APOE epsilon 2, epsilon 3, epsilon 4) remain controversial. Using a novel mass spectrometry-based method, we quantified total ApoE and specific ApoE isof
Hormone-mediated maternal effects play an important role in the formation of a differentiated phenotype. They have been shown to influence a wide array of offspring traits, both early in life and in adulthood. One important offspring trait that is under the influence of maternal androgens is the immune system. In birds, a growing number of studies show that yolk androgens modulate immune function
In Statoil, understanding and managing risk is today considered a core value. This principle has been duly integrated in the organization, and is inscribed in steering documents as well as in a booklet handed out to all employees, describing core values, corporate governance, the operating model and corporate policies. The company has developed a sophisticated approach to ERM that centers on the p
In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ec
The article investigates the notion of 'Christian Europe' by tracing some of its ideological roots. In particular, it engages with the Romantic era of German philosophy. If the idea of Europe from its very earliest stage was closely linked to Christianity, this gesture also became an important element in the attempts of a number of Romantic poets and philosophers to seek the foundations for a new
The project's main thesis is to verify the existence of local colours and colouring. The object for the research was dwellings in the rural areas of southern Sweden from the 19th century. In the rural areas of Sweden the most dominating traditional facade material is wooden panel. The colour at these facades is the traditional red-paint. It’s relevant for this project to take focus on geographical
Popular Abstract in Swedish Kroppens immunförsvar är vårt skydd mot främmande "inkräktare", såsom virus, bakterier och parasiter. Om dessa mikroorganismer tar sig förbi de fysiska barriärerna, dvs. hud, slemhinnor saliv mm, aktiveras immunsystemet. Immun-försvaret kan delas in i det nedärvda eller naturliga försvaret samt det för-värvade försvaret. Det naturliga försvaret aktiveras först och huvudInterleukin (IL)-1beta is one of the most pleiotropic and potent cytokines, produced predominantly by activated monocytes and macrophages. IL-1 plays an important role in normal immunoregulatory processes but also in pathophysiological inflammatory responses. In the present study, we developed a model for active IL-1beta secretion. A retroviral vector containing a cDNA construct encoding the matur
Popular Abstract in Swedish Riksdagen har beslutat att Sveriges energisystem ska ställas om. Målet är ett ekologiskt uthålligt samhälle där staten verkar för en säker, effektiv och miljövänlig tillförsel och användning av energi. Detta görs bland annat genom att stödja forskning om förnybara energikällor. Biogasen är här ett av flera möjliga alternativ och har också utnämnts till det mest miljöanpThe utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. There is a large unused potential of organic waste that is suitable for biogas production and the anaerobic digestion process has the potential of bec
