The molecular conservation of a surface-exposed lipoprotein, protein D, of Haemophilus influenzae was studied by cloning and sequencing of the gene encoding protein D from three encapsulated type b strains and three nontypeable strains of H. influenzae. These nucleotide sequences were analyzed with previously reported sequences from one type b strain and one nontypeable strain. The nucleotide sequ

Background. Several clinical studies have suggested possible increase in cardiovascular risk during and in the first weeks after an acute inflammatory disease. Using influenza vaccine as inflammatory stimulus, we investigated whether arterial endothelial dysfunction could persist beyond the inflammatory state, and whether amplified oxidative modification of low-density lipoprotein (LDL) accompanie

Analysing the variation in flight speed among bird species is important in understanding flight. We tested if the cruising speed of different migrating bird species in flapping flight scales with body mass and wing loading according to predictions from aerodynamic theory and to what extent phylogeny provides an additional explanation for variation in speed. Flight speeds were measured by tracking

Lysosomal cysteine proteases from mammalian cells and plants are regulated by endogenous tight-binding inhibitors from the cystatin superfamily. The presence of cystatin-like inhibitors in lower eukaryotes such as protozoan parasites has not yet been demonstrated, although these cells express large quantities of cysteine proteases and may also count on endogenous inhibitors to regulate cellular pr

Wetlands can modify and control nutrient fluxes between terrestrial and aquatic ecosystems, yet little is known of their potential as biological buffers and sinks in the biogeochemical silica cycle. We investigated the storage of amorphous silica (ASi) in a central-European riparian wetland. The variation in storage of ASi in the soil of an undisturbed wetland was significantly controlled by two f

Patellofemoral problems are relatively common sequelae of total knee arthroplasty (TKA), and many factors contribute to these complications. Vascular compromise has been identified as a possible contributing factor, and was selected for further investigation in the present study. Laser Doppler Flowmetry was used to quantify patella intraosseous blood flow in vivo during TKA surgery without the use

The FRR (Friendly Rest Room) project creates and evaluates prototypes of a more user friendly intelligent toilet for old persons and for persons with disabilities. Additionally, applicable knowledge regarding needs and wishes of old and/or disabled persons and their care persons are documented. In this paper the user driven research approach, ethical aspects and the iterative user centred design p

This paper presents findings from a qualitative study of young adults living in a relatively deprived metropolitan area in Sweden. The analysis of interview data yielded four separate types of neighbourhood discourses, each related to a major hegemonic ‘discourse of the problematic area’. The discursive model was used to disclose different patterns of vulnerability, at both the individual and the

In this talk I first present a short review of fluctuations in e (+) e(-) -annihilations. I then describe some new results on FD correlations. Experimental analyses of pp and Lambda Lambda correlations indicate a very small production radius. This result relies very strongly on comparisons with MC simulations. A study of the approximations and uncertainties in these simulations implies that it is

A three-dimensional numerical study was conducted to assess the hydraulic and heat transfer performance of primary surface type heat exchanger surfaces, called cross wavy (CW) ducts aimed for recuperators. The governing equations, i.e., the mass conservation equation, Navier-Stokes equations and the energy equation, are solved numerically by a finite volume method for boundary fitted coordinates.

The specific identity of neuronal precursors within the embryonic brain is, at present, not clear. Here we show that cultures with glial characteristics derived from the embryonic mouse or human lateral ganglionic eminence (LGE) can be expanded over many passages and maintain their glial identity. Interestingly, removal of serum and EGF from the culture medium results in the generation of large nu

Objective: It has earlier been demonstrated that capsaicin-induced desensitization improves insulin sensitivity in normal rats. However, whether increased capsaicin-sensitive nerve activity precedes the onset of insulin resistance in diet-induced obesity - and therefore might be involved in the pathophysiology - is not known. Further, it is of relevance to investigate whether capsaicin desensitiza
