Mycobacterium bovis bacilli Calmette-Guerin regulates leukocyte recruitment by modulating alveolar inflammatory responses.

Leukocyte migration into the epithelial compartment is an important feature in the active phase of mycobacterial infections. In this study, we used the Transwell model to investigate the mechanisms behind mycobacteria-induced leukocyte recruitment and investigated the role of TLR2 and TLR4 in this process. Infection of epithelial cells resulted in significantly increased secretion of the neutrophi

Simulated "real" worlds: Actions mediated through computer game play in science education

Over the last decade, a great variety of visionary ideas and beliefs have been brought forward, regarding the potentials of using computer games as a tool for learning and mediation in educational settings. This thesis aims at contributing to research in this field, by empirically exploring what happens when students play and reflect on their computer game play in science education. Three empirica

Exact fidelity and full fidelity statistics in regular and chaotic surroundings

For a prepared state exact expressions for the time-dependent mean fidelity as well as for the mean inverse participation ratio are obtained analytically. The prepared state is taken as an eigenstate of the unperturbed system, and the studied fidelity is identical to the survival probability. The full distribution functions of fidelity in the long-time limit and of inverse participation ratio are

Wiring of pyranose dehydrogenase with osmium polymers of different redox potentials.

In this study, five different flexible osmium based redox polymers were investigated for their ability to efficiently "wire" the oxidoreductase pyranose dehydrogenase (PDH, EC 1.1.99.29) from Agaricus meleagris, on graphite electrodes for possible applications in biofuel cells. A series of newly synthesised osmium based redox polymers covering the potential range between -270 and +160mV vs. Ag|AgC

Topological effects on capsomer-polyion co-assembly

On the basis of a T = 1 icosahedral capsid model, the capsomer-polyion co-assembly process has been investigated by molecular dynamics simulations using capsomers with different net charge and charge distribution as well as linear, branched, and hyper-branched polyions. The assembly process was characterized in terms of the time-dependent cluster size probabilities, averaged cluster size, encapsul

Identity, choice and consumer freedom - the new opiates? A psychoanalytic interrogation

Psychoanalysis opens a variety of windows into understanding contemporary consumption and consumerism. The psychoanalytic theory of defence and the unconscious enables us to understand why commodities, from fast cars to luxury chocolate, so readily stand in to offer substitute gratification for deeper repressed desires and why the meaning of such commodities is liable to become mobile and unstable

Metformin induces lactate production in peripheral blood mononuclear cells and platelets through specific mitochondrial complex I inhibition.

Metformin is a widely used antidiabetic drug associated with the rare side effect of lactic acidosis which has been proposed to be linked to drug-induced mitochondrial dysfunction. Using respirometry, the aim of this study was to evaluate mitochondrial toxicity of metformin to human blood cells in relation to that of phenformin, a biguanide analogue withdrawn in most countries due to a high incide

The proposed giant planet orbiting VB 10 does not exist

We present high-precision relative radial velocities of the very low mass star VB 10 that were obtained over a time span of 0.61 years as part of an ongoing search for planets around stars at the end of the main sequence. The radial velocities were measured from high-resolution near-infrared spectra obtained using the CRIRES instrument on the Very Large Telescope with an ammonia gas cell. The typi

The impact of dyslipidaemia on incidence of coronary heart disease in Finns and Swedes with different categories of glucose tolerance

Background: The association of dyslipidaemia with incidence of coronary heart disease (CHD) has not been well studied in people with different glucose categories. Methods: Data from six population-based prospective studies in Finland and Sweden, with 4818 men and 4269 women aged 25-89 years who were free of CHD and without a prior history of diabetes at baseline, were jointly analysed. Multivariat

Individual progression of carotid intima media thickness as a surrogate for vascular risk (PROG-IMT): Rationale and design of a meta-analysis project

Carotid intima media thickness (IMT) progression is increasingly used as a surrogate for vascular risk. This use is supported by data from a few clinical trials investigating statins, but established criteria of surrogacy are only partially fulfilled. To provide a valid basis for the use of IMT progression as a study end point, we are performing a 3-step meta-analysis project based on individual p

The Harmony in Life Scale Complements the Satisfaction with Life Scale: Expanding the Conceptualization of the Cognitive Component of Subjective Well-Being

Conceptually, the Satisfaction with Life Scale (SWLS; Diener et al. in J Pers Assess 49(1):71–75, 1985) emphasizes evaluations comparing actual and expected life circumstances. Contrastingly we developed the Harmony in Life Scale (HILS) emphasiz-ing psychological balance and flexibility in life. Study 1 (476 participants) developed the HILS. In Study 2 participants (N = 787, T1; N = 545, T2) answe

Adjusting parameters of aortic valve stenosis severity by body size

Background Adjustment of cardiac dimensions by measures of body size appears intuitively convincing and in patients with aortic stenosis, aortic valve area (AVA) is commonly adjusted by body surface area (BSA). However, there is little evidence to support such an approach. Objective To identify the adequate measure of body size for the adjustment of aortic stenosis severity. Methods Parameters of

Calorespirometry of terrestrial organisms and ecosystems.

Calorespirometry is the simultaneous measurement of heat and gas exchange from biological systems. Such measurements can be used to assess fundamental properties of many different types of systems from small ecosystems to isolated tissues. Techniques for calorespirometric measurements on terrestrial (non-aquatic) samples are described. Methods and models for evaluation of carbon conversion efficie

Surface Deposition and Phase Behavior of Oppositely Charged Polyion-Surfactant Ion Complexes. 2. A Means to Deliver Silicone Oil to Hydrophilic Surfaces

The delivery of emulsified silicone oil to hydrophilic silica surfaces by mixtures of cationic polysaccharides and SDS has been studied by in situ null ellipsometry, dynamic light scattering, and turbidity measurements. The emulsion contained silicone oil droplets with a hydrodynamic radius of 18 rim, stabilized by anionic and nonionic surfactants. The investigated polysaccharides were cat-guar an

Molecular basis of hereditary C1q deficiency-revisited: identification of several novel disease-causing mutations

C1q is the central pattern-recognition molecule in the classical pathway of the complement system and is known to have a key role in the crossroads between adaptive and innate immunity. Hereditary C1q deficiency is a rare genetic condition strongly associated with systemic lupus erythematosus and increased susceptibility to bacterial infections. However, the clinical symptoms may vary. For long, t
