Arterial remodeling and plasma volume expansion in caveolin-1 deficient mice.

Caveolin- 1 ( Cav- 1) is essential for the morphology of membrane caveolae and exerts a negative influence on a number of signaling systems, including nitric oxide ( NO) production and activity of the MAP kinase cascade. In the vascular system, ablation of caveolin- 1 may thus be expected to cause arterial dilatation and increased vessel wall mass ( remodeling). This was tested in Cav- 1 knockout

Thermal properties of three sets of garments measured with a heated sweating mannequin

The choice of proper insulation for cold protection is important. However, “proper insulation” depends on activity and at lots of jobs the activity varies along the working day. The choice of low insulation for high metabolic rate makes people feel cold during low activity levels and the choice of high insulation for low metabolic rate makes them feel hot and sweat during high activity levels. The

Abstract in French Cet article est basé sur l’analyse de deux corpus de français écrit langue étrangère par des apprenants suédois ; l’un transversal et l’autre longitudinal. Les deux corpus permettent des approches différentes, l’une de caractère linguistique mettant l’accent sur le profil développemental de l’accord en nombre ; l’autre plus cognitive analysant les aspects des connaissances expliThis article is based on an analysis of two corpora in French as a foreign language by Swedish learners; one cross-sectional and the other longitudinal. These two corpora lent themselves to different approaches: a linguistic approach which stressed the developmental profile of agreement in number; and a more cognitive approach which analyzed various aspects of explicit and implicit knowledge in th

In vitro sliding of actin filaments labelled with single quantum dots

We recently refined the in vitro motility assay for studies of actomyosin function to achieve rectified myosin induced sliding of actin filaments. This paves the way, both for detailed functional studies of actomyosin and for nanotechnological applications. In the latter applications it would be desirable to use actin filaments for transportation of cargoes (e.g., enzymes) between different predet

ForSAFE - an integrated process-oriented forest model for long-term sustainability assessments

Planning management activities for a long-term sustainable forestry requires predictive tools designed for this kind of management. Many tools available today are either designed for planning periods that are too short to consider long-term sustainability, omit important parts of the forest ecosystem or are not capable of considering environmental changes. A long-term potential growth-limiting fac

Patterns of Value : Essays on Formal Axiology and Value Analysis, vol. 1

Discussions about values are common in many contexts. Often, what is debated is the choice of means to realize or protect various values, but sometimes the discussion concerns the very values that ought to be realized or protected. Philosophical debate in this area has mainly been focused on two kinds of issues. Philosophers have tried to identify the set of fundamental values, i.e., to provide wh

Transcranial cerebral oximetry related to transcranial Doppler after aneurysmal subarachnoid haemorrhage

Noninvasive methods for detecting cerebral artery vasospasm, still a serious complication following aneurysmal subarachnoid haemorrhage, are of vital interest. Up-to-date transcranial Doppler ultrasound (TCD) has proved to be sensitive in detecting vasospasm in the middle cerebral artery, but has less accuracy for other cerebral arteries. Transcranial cerebral oximetry (TCCO) is a new non-invasive

The Kaposi's sarcoma-associated herpesvirus complement control protein (KCP) binds to heparin and cell surfaces via positively charged amino acids in CCP1-2.

The Kaposi's, sarcoma-associated herpesvirus (KSHV) complement control protein (KCP) inhibits the human complement system, and is similar in structure and function to endogenous complement inhibitors. Other inhibitors such as C4d-binding protein and factor H, as well as the viral homologue vaccinia virus complement control protein are known to bind heparin and, for the two latter, also to glycosam

Effects of topical formoterol alone and in combination with budesonide in a pollen season model of allergic rhinitis.

Background: beta(2)-Agonists may exert mast cell stabilizing and anti-plasma exudation effects. White available data suggest no or only marginal effects of beta(2)-agonists on symptoms of allergic rhinitis, little is known about whether these drugs may add to the efficacy of anti-rhinitis drugs. Objective: To examine effects of a beta(2)-agonist, alone and in combination with an intranasal glucoco

On methods for pattern recognition with application to epileptic electroencephalograms

Popular Abstract in Swedish Elektroencefalogrammet (EEG), dvs mätning av potentialer på skalpen, är en relativt enkel och gammal teknik för att studera hjärnans aktivitet. Trots de stora framstegen inom s k brain-mapping-tekniker på senare år (magnetröntgen, PET, SPECT), är EEG fortfarande ett viktigt verktyg för diagnos. En av dess fördelar gentemot andra tekniker är dess fina tidsupplösning. EtThe thesis treats methods for pattern recognition in multichannel electroencephalogram (EEG) signals, for application to diagnostics of epilepsy. Parts I-IV treat methods for feature extraction and clustering of EEG spikes, occurring between epileptic seizures, and part V presents a method for filtering seizure onset EEG signals. In part I, Hermite functions are used for parametric description of

Purification of IgD from human serum - A novel application of recombinant M. catarrhalis IgD-binding protein (MID).

Moraxella catarrhalis IgD-binding protein (MID) is a multimeric outer membrane protein belonging to the family of autotransporters. The IgD-binding domain of MID is located between amino acids MID 962-1200 and binds to amino acids 198-224 of the IgD C(H)1 region. In the present study, we describe a method to purify IgD from serum with high levels of IgD using a two-step affinity chromatography pro
